The present invention relates to a drive transmission mechanism, which uses a planetary gear mechanism. The present invention also relates to an inkjet recording device, which delivers the ink to a medium for recording, thereby performing recording by using such a drive transmission mechanism.

Up to the present time were known recording device, which includes a feed mechanism for feeding a sheet as a medium for recording in its inner part, a gear mechanism for moving the submitted sheet, a recording mechanism for recording data or image on a fed sheet and excretory mechanism for issuing a recorded sheet on the outer side of the recording device. The recording device also includes a source of motion for the propulsion of appropriate mechanisms and the drive transmission mechanism.

Among such recording devices inkjet recording device includes a recording head as a recording mechanism and serves the ink on the sheet, thereby recording data or images. Many ink-jet recording device equipped with a mechanism for recovery of the head, containing the suction pump to maintain the normal condition of the ink supply is opisyvayuscii head or restore the normal condition of the ink supply in case of clogging of the holes for the ink supply.

As described above, many different mechanisms are installed in the recording device, and sources of traffic, such as electric motors, installed to actuate the appropriate mechanisms when necessary. In many cases, the recording device includes a switching mechanism of transmission for selective transmission of the driving force single source traffic to multiple mechanisms. Known for the design of the switching mechanism of transmission uses a planetary gear mechanism. The use of the planetary gear mechanism makes it possible to reduce the number of sources of traffic or the number of drive elements. In the inkjet recording device can be manufactured at low cost and small size, and its reliability can be improved by simplifying mechanisms.

For example, the well-known design, which uses a planetary gear mechanism, so that one of the two different destinations of transmission is selected between the right rotation and left rotation (reference should be made, for example, Japanese patent No. 2628686). However, this design cannot properly perform the transmission of the movement, if you have more than two destinations motion. In addition, the above structure of the rotating driving force in one direction can be transmitted in one destination of transmission. However, torque is the driving force in two directions, as in right and left directions of rotation cannot be transmitted in one destination motion.

In addition, a well-known design, which uses a planetary gear mechanism, which rotates in the direction of rotation, providing rotation of the planetary gear and which rotates in the left direction of rotation, passing the driving force in the destination of transmission, so that the driving force can be transmitted in two or more of the destination of transmission (reference should be made, for example, in Japanese laid patent application No. 2002-310260). However, the above structure only torque driving force in one direction can be transmitted in one destination motion.

In addition, a well-known design, which uses an additional source of motion, such as a solenoid, solely for the switching mechanism of transmission (reference should be made, for example, Japanese patent No. 2855580). The design provides the state in which the planetary gear can rotate freely, and the state in which the rotational movement is limited to switch between them, so that the driving force in right and left directions can be transmitted in more than h is m two destination motion. However, for the specified design you must have a source of motion only for the switching mechanism of transmission and detector, such as a sensor for angular position of the planetary gear.

In addition, if the number of destinations of transmission is increased, the angle of rotation of the planetary gear when installed in the initial state angular position of the planetary gear increases. As a result, it takes time for the rotation of the planetary gears, and thus the time required to complete the operation, the gear shift movement increases.

The aim of the present invention is to provide a drive transmission mechanism and ink jet recording device for fast switching operation and improving the reliability of the operation of the switching mechanism, the gear shift movement.

In accordance with an aspect of the present invention described drive gear, which includes the drive source capable of generating rotational driving force, and drive the top gear host, is capable of transmitting torque driving force of the drive source. Drive transmission device additionally includes a switching mechanism transmitting motion, comprising a solar gear, planetarysystem and the planetary lever, capable of supporting the planetary gear to freely rotate around the sun gear, and a switching mechanism of transmission is capable of selectively switching the rotating driving force from the drive transmission node to the many destinations transfer movement. In addition, the drive transmission device includes many of the leading input gears, capable of transmitting rotational driving force transmitted from the switching mechanism of transmission in the destination of transmission; a clamping device capable of switching the state of rotation of the planetary gears between the state of free rotation, in which the rotating driving force of the sun gear is transmitted to the planetary lever, so that the planetary lever is able to rotate, and the condition of limited rotation, in which the rotating driving force of the sun gear is not transmitted to the planetary lever, so that the planetary lever is not able to rotate; and a node of the switching state of rotation, capable of clamping action the device by moving the planetary gear in the axial direction of the center of rotation, thus switching between the state of limited rotation and the state of free rotation. In the condition of a limited rotation of the planetary pole is nya engages with the leading of the input gear, and clamping device is not capable of transmitting torque driving force. In a state of free rotation of the planetary gear unlinked with the leading of the input gear, and a clamping device capable of transmitting torque driving force. The switching mechanism of transmission includes first and second support parts, which are made with the possibility of entering into contact with the planetary lever is pivoted in a state of free rotation, for installation in the initial state angular position of the planetary gear. The switching mechanism of transmission is able to select one of the first and second support parts, which will come into contact with the planetary lever in accordance with the leading position of the input gear, the transmission torque of the driving force, among many leading input gears.

In accordance with another aspect of the present invention described drive gear device that includes the drive source capable of generating rotational driving force, and drive the top gear host, is capable of transmitting torque driving force of the drive source. Drive transmission device additionally includes a switching mechanism of transmission that contains a sun gear, planetary gear and the planetary lever capable of supporting PLA is eternal gear for free rotation around the sun gear, moreover, the switching mechanism of transmission is capable of selectively switching the rotating driving force from the drive transmission node to the many destinations transfer movement. In addition, the drive transmission device includes many of the leading input gears, capable of transmitting rotational driving force transmitted from the switching mechanism of transmission in the destination of transmission; a clamping device capable of switching the state of rotation of the planetary gears between the state of free rotation, in which the rotating driving force of the sun gear is transmitted to the planetary lever, so that the planetary lever is able to rotate, and the condition of limited rotation, in which the rotating driving force of the sun gear is not transmitted to the planetary lever, so that the planetary lever is not able to rotate; and a node of the switching state of rotation, capable of clamping action the device by moving the planetary gear in the axial direction of the center of rotation, thus switching between the state of limited rotation and the state of free rotation. In a state of free rotation of the planetary gear is disengaged from the sun gear and the leading of the input gear, the clamping mechanism is capable of re is avati torque driving force, and node toggle the state of rotation is moved to the first position, in which it comes in contact with the switching mechanism of transmission. In the condition of a limited rotation of the planetary gear engages with the sun gear and the leading of the input gear, respectively, a clamping device is not capable of transmitting torque driving force, and the node toggle the state of rotation is moved to the second position, in which it is detached from the mechanism, the gear shift movement. The planetary gear has a ready state of rotation, in which the planetary gear engages with the sun gear of the leading input gear, respectively, a clamping device is not capable of transmitting torque driving force, and the node toggle the state of rotation is moved to a third position located between the first position and the second position.

In accordance with aspects of the present invention, since the first and second support parts are designed for installation in the initial state angular position of the planetary gear, a supporting part which is in contact with the planetary lever, thus setting in the initial state angular position can be selected from the two bearing parts in accordance with the leading position of the input gear, the transmission DV the driving force.

The pickup roller 44 is located on the opposite side of the pressure plate 43, and the pressure plate 43 is tightened in the direction of the feed roller 44 with neprolongirovannogo spring pressure plate. Listootdelki roller 45 also tightened in the direction of the feed roller 44 with neprolongirovannogo spring listootdelki roller. The trajectory of the sheet downstream from listootdelki roller 45 in the direction of movement converges in the following channel 64 of the cassette to move the sheet, which is connected with the following recording mechanism 7.

The recording mechanism 7 of the recording head 71 is installed on the carriage 73, and neprogruntovannye hole for supplying ink is formed on the lower surface of the recording head 71. On the opposite side of the hole to supply ink bumagoopornogo roller 77 is located with a specified gap between them. The left front roller 78 is located upstream to buyhoodia roller 77 in the direction of movement of the sheet 42, and the left front pressure roller 79 is tightened toward the left front roller 78 neprolongirovannogo spring.

In addition, the discharge tray 83 is located further downstream from the outlet roller 81 in the direction of movement.

Capacity for 72 ink also mounted on the carriage 73 together with the recording head 71, so that the ink is fed from the tank 72 to the ink in the recording head 71. The driving force of the motor 75 of the carriage is transmitted to the recording head 71 through a belt 76 of the carriage, which is a toothed belt drive. Thanks to such design, the carriage 73 can perform the reciprocating movement along the guide 74 of the carriage in the main scanning direction (i.e. the direction vertically intersecting the direction of movement of the sheet 42).

The mechanism 9 for the recovery head is outside the range of the main scan for recording data or images on the sheet 42, and the cover 91 is located on the mechanism 9 to restore the head parallel buyhoodia roller 77. The suction pump 92 is connected to the cover 91 through neprolongirovannogo tube. The cleaning device 93 is located near the cover 91.

In this embodiment, an inkjet recording device that contains additional feed slot other than the holes 41 for submission, will be described as an example. Mechanism 5 feed cassette is located in the lower part of the inkjet recording condition the device 1. Mechanism 5 feed cassettes made with the possibility of the contents of the cartridge 51, the pickup roller 52 of the cassette and part 53 to separate cassettes. The sheets 42 are formed on the cartridge 51, the part 53 for separating cartridge and transfer roller 52 of the cartridge are located in the vicinity of the front end of the sheet 42 in the direction of its movement, and gear mechanism 6 of the cassette is located downstream of the direction of movement. The transfer roller 61 of the cassette is located in the channel 64 of the cassette to move the sheet transfer mechanism 6 cassettes, and the transfer pressure roller 62 is tightened in the direction of the transfer roller 61 of the cassette neprolongirovannogo spring gear pressure roller cassette. In addition, the channel 64 of the cassette to move the sheet is connected so that the sheet 42 is moved in an arc between the part 53 to separate cassettes and recording mechanism 7. Gear motor 63 of the cassette is located in the vicinity of the side surface of the feed mechanism 6 of the cassette, so that the rotating driving force of the transfer motor 63 of the cassette is transferred to the transfer roller 61 of the cassette through neprolongirovannogo drive circuit.

Fig.9 depicts a perspective view illustrating the state in which the planetary lever comes in contact with the second rotary abutment edge in the switching mechanism of transmission. Fig depicts a view illustrating a state of free rotation of the switching mechanism of transmission, and Fig depicts a view illustrating the state of a limited rotation of the switching mechanism of transmission.

3 and 4 illustrate a state in which torque is the driving force of the transfer motor 63 of the cassette is transmitted to the sun gear 21 through neprolongirovannogo drive circuit. The sun gear 21 forms a plan of the container gear with the planetary gear 22. The planetary gear 22 is supported by the planetary lever 23, which is the supporting member. The planetary arm 23 is supported in such a way as to freely rotate around the center of rotation of the sun gear 21, causing the planetary gear 22 is supported by the planetary lever 23 in such a way as to engage with the sun gear 21 to rotate around the sun gear 21.

The shaft 25, which is common shaft passing, is located in the center of rotation of the sun gear 21 and the center of rotation of the planetary arm 23, that is at the center of rotation of the planetary gears 22. The sun gear 21 and the shaft 25 are made as one unit with each other. The planetary arm 23 is supported rotatably by the shaft 25 in such a way as to freely rotate around the center of rotation of the sun gear 21. Additionally, there are output coupler 26a as including a mechanism for transmitting torque driving force of the sun gear 21 through a shaft 25. The input coupler 26b as the clamping device is located in a position opposite to the output coupling 26a. The output coupler 26a has a gear shape, made with external teeth. Input clutch 26b is made with internal teeth that engage with the outer teeth of the output coupling 26a. The input coupler 26b and the planetary lever 23 is designed as one is aloe with each other. The planetary lever 23, the planetary gear 22 and the input clutch 26b are supported in such a manner as to move in the axial direction of the shaft 25 and, consequently, to move in the axial direction of the center of rotation of the planetary gears 22. In addition, the compressed spring 24 of the planetary lever is located between the body 27 of the clutch input and clutch 26b, and the wall of the housing 27 of the coupling is located between the planetary lever 23 and the spring 24 of the planetary lever. The spring 24 of the planetary lever causes the planetary lever 23 to contact firmly with the body 27 of the coupling. The input coupler 26b and the output coupler 26a positioned within a housing 27 of the coupling. Part of the planetary arm 23 and the part of the shaft 25 are placed in the housing 27 of the coupling. The body 27 of the coupling is tightened in the same direction as the axial direction of the center of rotation of the planetary gears 22 under the action of buoyancy force of the spring 28 and the clutch housing.

As shown in Fig and 9, the lever 27a the clutch housing is made as one piece with the outer circumference of the housing 27 of the coupling so that is from him. The lever 27a the clutch housing is located in a position in which it comes in contact with the carriage 73, when the carriage 73 as a node for switching the state of rotation makes reciprocating motion in the main scanning direction. The main scanning direction of the carriage 73 is identical to sevosa direction of the shaft 25. When the carriage 73 presses the lever 27a the clutch housing in the right direction in figure 3 against the buoyancy force of the spring 28 housing clutch housing clutch 27 is moved along the shaft 25 together with the input clutch 26b. Therefore, when the carriage 73 is detached from the lever 27a the clutch housing, the carriage 73 moves the body 27 of the coupling in the axial direction of the shaft 25. When the planetary gear 22 is moved to the position in which it engages with the sun gear 21 under the action of the spring 28 the clutch housing and the spring 24 of the planetary lever. In addition, the output coupler 26a and the input clutch 26b are detached from each other in the axial direction of the shaft 25. This condition will be called a state a limited rotation (see Fig).

On the other hand, when the carriage 73 presses the lever 27a of the housing of the coupling against the buoyancy force of the spring 28 housing clutch housing clutch 27 is moved in the axial direction of the shaft 25. When the planetary gear 22 is installed in the position in which it is not engaged with a sun gear 21, and the output coupler 26a and the input clutch 26b are in positions in which they are meshed with each other. This state is called a state of free rotation (see Fig). Thus, by moving the planetary gear 22 in the axial direction of the center of rotation of the mechanism of inclusion is in action is selected.

As shown in figure 4-9, around the zone of rotation of the planetary gears 22 are many leading input gear (driven gear) for transmitting torque of the driving force corresponding mechanisms. As leading input gear provided by the leading of the input gear 40 for supplying to the transmission torque of the driving force of the feed mechanism 4 through a chain drive (not illustrated) and the leading of the input gear 90 to restore the head to transmit torque of the driving force mechanism 9 recovery head using a chain drive. In addition, as leading input gears, provided by the leading of the input gear 50 for feeding the tape to the transmission torque of the driving force mechanism 5 feed cassette using a chain drive.

In addition, the shafts 32b, 32c and 32d for fixing the planetary arm to limit rotation of the planetary arm 23 is located in the zone of rotation of the planetary arm 23 in the relevant provisions, in which the planetary gear 22 engages with the respective lead of the input couplers 40, 50 and 90. In addition, the shaft 32a for fixing the planetary arm to limit rotation of the planetary arm 23 is located in the zone of rotation of the planetary arm 23 in the position in which the planetary gear 22 is not engaged with any of the leading input gears 40, 50 and 90. The shaft 32a of desacralize planetary lever is arranged to limit the rotation of the planetary arm 23 in a state of limited rotation, so the planetary arm 23 is not able to rotate. Hole 23a formed in the planetary lever 23 and the rotating shaft of the planetary gear 22, which is made as one unit with the planetary lever 23, so that the rotation of the planetary arm 23 is limited when the shafts 32a, 32b, 32c and 32d for fixing the planetary lever pass through the hole 23a. In a state of free rotation of the planetary arm 23 is disconnected from the shafts 32a, 32b, 32c and 32d for fixing the planetary lever in the axial direction of the center of rotation. Thanks to such design, in a state of free rotation, the rotation of the planetary arm 23 is not limited to the shafts 32a, 32b, 32c and 32d for fixing the planetary lever, and, therefore, the planetary gear 22 is able to rotate.

In the following description, for convenience, the position where the planetary gear 22 engages with the leading of the input gear 40 for filing in a state of limited rotation, will be called the supply position B, and the position in which the planetary gear 22 engages with the leading input gear 90 to repair the head is called the recovery position C of the head. In addition, the position where the planetary gear 22 engages with the leading input gear 50 for filing in the cassette, will be called a regulation D filing in the cartridge, and the position in catalonia.nearly gear 22 is not engaged with any of the leading input gears 40, 50 and 90, will be called a neutral position.

In this example implementation is illustrated a construction in which there are four shaft 32a, 32b, 32c and 32d for fixing the planetary lever so that rotation of the planetary arm 23 is limited in four positions A, B, C, and D. However, this embodiment is not limited to this design, and the number of positions in which the rotation of the planetary arm 23 is limited, can be increased additionally provided, which may be provided with sufficient space for the placement of the elements. Thus, a number of mechanisms, which are the destination of transmission of the driving force, in which the rotating driving force is transmitted by the mechanism 2, the gear shift motion can be increased if necessary.

Then discusses the swivel support ribs as the first and second contact sections, which are brought into contact with the planetary lever 23, with reference to Fig and 9. Swivel support ribs 31a and 31b are in contact with the planetary lever 23 in a state of free rotation, thus limiting the range of rotation of the planetary arm 23. In this embodiment, the first rotary abutment rib 31a comes into contact with the planetary lever 23 during right rotation of the gear of the electric motor is El 63 of the cassette, and second swivel support rib 31b is in contact with the planetary lever 23 during left rotation of the gear motor 63 of the cartridge. That is, the planetary arm 23 is made to rotate between the first rotary abutment rib 31a and the second rotary support rib 31b. In addition, within the range of rotation of the planetary arm 23, the first rotary abutment rib 31a and the second rotary support rib 31b, the neutral position A, position B to the filing, the position C of the recovery head and regulation D filing in the cartridge are located in this order. Mechanism 2, the gear shift movement is controlled by the circuit 100 controls (figure 10) so that the planetary arm 23 is in contact with the rotary support rib positioned close to the leading of the input gear that transmits driving force between the first and second swivel support ribs 31a and 31b.

When the rotation goes from a state of free rotation in the condition of limited rotation in a state in which the planetary arm 23 is in contact with the first rotary abutment rib 31a, the planetary arm 23 is fixed in the neutral position A. similarly, when the rotation goes from a state of free rotation in the condition of limited rotation in a state in which the plan is ary lever 23 is in contact with the second rotary support rib 31b, the planetary arm 23 is fixed in position In the feed cassette.

Then management description number of write operations in accordance with the first embodiment will be given with reference to figure 10 and 11. Figure 10 depicts a block diagram of the control and 11 depicts the precedence diagram for describing a write operation.

Figure 10 circuit 100 controls the recording device is configured to enable the Central processor 101, is responsible for controlling a recording device, a ROM 102 that stores programs, various tables and data, such as integers, and RAM 103 for temporarily storing information. The circuit 100 also contains a device for driving the recording head 71 and a device for the propulsion of motor 73 of the carriage, a gear motor 63 of the cassette and the front left of the motor 104.

The encoder 105 position is able to determine the position of the carriage. The encoder 106 provisions can detect the rotation angle of the gear on the motor 63 of the cartridge. The encoder 106 may be configured to determine the angle of rotation on the output shaft of the gear motor 63 of the cassette and can be performed with the indirect determination of the rotation angle determined by the value of the angle of rotation of the intermediate gear, transmitting the driving force from the gear motor 63 of the cassette to the sun gear 21.

Figure 11 when starting the write operation, first, determines whether the selected normal feed or supply in the cassette (step S11). When issuing commands normal feed operation is performed, the gear shift movement in the feeding position (S21), whereas when issuing commands feed cassette is executed, the operation of switching the transmission of motion to the feeding position in the cassette (S21). A detailed description of the operation of switching the transmission of motion will be given below. When using this operation, the rotating driving force of the transfer motor 63 of the cassette can be transferred to the feed mechanism 4 or mechanism 5 feed cassette mechanism 2, the gear shift movement and neprolongirovannogo chain drive.

First will be described a case of receiving the command with the normal flow. The feed mechanism 2 transmits the rotational driving force of the transfer motor 63 of the cassette feed roller 44. Then the operation of the feed is performed by separating a single sheet from a stack of sheets 42, located in the hole 41 for feeding, using the pressure plate 43 and listootdelki roller 45. Then the feed mechanism 4 moves the separated one sheet 42 in the clamping between the left front roller 78 and the left plumage is it the pressure roller 79 in part of the channel 64 of the cassette to move the sheet, thus completing the operation of the feeder (step S22).

Then will be described a case of receiving the command feed cassette. Mechanism 5 feed cassette transmits rotational driving force of the transfer motor 63 of the cassette feed roller 62 of the cassette using neprolongirovannogo chain drive. Then the operation of the feed cassette is performed by separating a single sheet from a stack of sheets 42, located in the cassette 51, using cassette 51, the pickup roller 52 of the cassette and part 53 to separate cassettes. Then the mechanism 5 feed cassette moves the separated one sheet 42 in the clamping between the transfer roller 61 of the cassette and transfer the pressure roller 62 of the cassette through the channel 64 of the cassette to move the sheet, thus completing the operation of the feed cassette (step S32).

The pickup roller 52 of the cassette does not need to operate after the front end of the sheet 42 reaches the position of the clamp between the transfer roller 61 of the cassette and transfer the pressure roller 62 of the cartridge. The reason is that the next sheet 42 may be useless filed, if the pickup roller cassette 52 is continuously driven. Therefore, when the operation of the feed cassette is completed, the planetary gear 22 is switched to the neutral position A (step S33).

After that the front end of the sheet 42 plumage is asaeda in the position of the clamp between the left front roller 78 and the left front pressure roller 79 in the channel 64 of the cassette to move the sheet due to the movement of the transfer roller 61 of the cassette (step S34).

After this time the normal operation of the feeder and feed cassette follow the same procedures. The left front roller 78 rotates due to the rotation of the front left of the motor 104. Left front pressure roller 79 is rotated in such a way as to follow the rotation of the front left roller 78 under the action of buoyancy efforts neprolongirovannogo spring-left front pressure roller. When the sheet 42 reaches the position of the clamp between the left front roller 78 and the left front pressure roller 79, the front end of the sheet 42 is installed in the position of the clip so that the sheet 42 is clamped between the left front roller 78 and the left front pressure roller 79, resulting starts moving sheet 42. The left front roller 78 moves the sheet 42 to until the front end of the sheet 42 reaches the position between the recording head 71 and boomgaarden roller 77 (step S12).

Then you write operation by the ink on the sheet 42 with successive repetition of the main scan of the carriage 73 and move the sheet of the front left roller 78 (step S13).

When the flow of ink to form images in accordance with the write commands is completed, the sheet 42 is clamped by the outlet roller 81 and the spur gear 82 is moved to the I to the discharge tray 83 on the outer side of the inkjet recording device 1, thus performing the unloading operation (step S14).

This description is governance (procedures) number of recording devices. On the other hand, if you want to perform a restore operation head before, during or after recording to maintain the normal condition of the ink supply ports of the recording head 71 executes the switching operation of the transmission in position C of the recovery head. A detailed description of the operation of switching the transmission of motion will be given below. After that, the rotating driving force of the transfer motor 63 of the cassette is transferred to the recovery mechanism 9 of the head, and a restore operation is running head using a cap 91, the suction pump 92 and purifying device 93.

Then a detailed description of the operation of switching the transmission of motion will be given with reference to Fig and 13. Fig depicts the precedence diagram for describing the operation of switching the transmission of motion to the feeding position in accordance with the first embodiment, and Fig depicts the precedence diagram for describing the operation of switching the transmission of motion in the recovery position of the head in accordance with the first example.

After receiving the command to perform the operation of switching the transmission and the position B of the feed motor 75 of the first carriage is driven to move the carriage 73 over mechanism 9 recovery head in the neighborhood of the mechanism 2, the gear shift movement. The carriage 73 moves continuously, so that the carriage 73 is in contact with the lever 27a the clutch housing. The carriage 73 is moved further, so that the casing 27 of the clutch is moved in the axial direction of the center of rotation against the buoyancy force of the spring 28 and the clutch housing. When moving the enclosure 27 of the coupling of the planetary gear 22, the planetary arm 23 and the input clutch 26b is moved under the action of buoyancy force of the spring 24 of the planetary lever. The motor 75 of the carriage is driven up until the encoder 105, the position of the carriage is determined that the carriage 73 is moved to the position denoted by the reference position 73a on Fig.

When the planetary gear 22 is moved to the position illustrated in Fig, the planetary gear is disconnected from the sun gear 21, and the output coupler 26a engages with the input clutch 26b (step S41). This state is called a state of free rotation.

In free rotation when the gear motor 63 of the cassette is driven to rotate the sun gear 21, the output coupler 26a and the input clutch 26b rotate with the shaft 25, so that the planetary gear 22 and the planetary lever 23 can rotate (step S42).

In free rotation of the gear motor 63 of the cassette rotates in the right direction the rotation. Then the planetary lever 23 comes in contact with the first rotary abutment rib 31a during the rotation, as illustrated in Fig (step S43).

When the planetary arm 23 is in contact with the first rotary abutment rib 31a, gear motor 63 of the cassette becomes unable to rotate in the direction of rotation. When the encoder 106 of the provisions of the chain drive determines that the planetary arm 23 has come in contact with the first rotary abutment rib 31a, and gear motor 63 of the cassette is stopped, the gear motor 63 of the cartridge stops. This operation is an operation in the initial state of the position of rotation of the planetary arm 23, that is, the rotation position of the planetary gear 22 through the first swivel support ribs 31a (step S44).

Then the gear motor 63 of the cassette is rotated at a given angle in the left direction of rotation when the control encoder 106 provisions of the chain drive. The given angle is the rotation angle, which is calculated on the basis of the angle of rotation required to achieve the planetary lever 23 to the position B of the feed from the first rotary abutment rib 31a (step S45).

Then the carriage 73, which presses the lever 27a of the housing of the clutch is moved to its original position. Then the body 27 of the coupling and returns to the initial position under the action of buoyancy force of the spring 28 and the clutch housing. In addition, the planetary gear 22, the planetary arm 23 and the input clutch 26b also return to their original position under the action of buoyancy force of the spring 24 of the planetary lever. When the planetary gear 22 engages with the sun gear 21 and the leading of the input gear 40 to supply, and the output coupler 26a and the input clutch 26b are detached from each other (step S46). This state is called a state a limited rotation (step S47).

This description represents the operation for switching the transmission of motion to position B supply. Then, description will be given of the operation of switching the transmission into the neutral position.

Since the switching operation of the transmission in the neutral position A is essentially the same as the operation of switching the transmission of motion to position B to the filing, it will be described only other operation.

By changing the angle of rotation during the rotation of the gear motor 63 of the cassette in the left direction of rotation in step S45, the planetary arm 23 is rotated to move to the neutral position A. Operation different from the operation in step S45 are the same as the operation of switching the transmission of motion to position B supply. As described above in the first embodiment, since the neutral position and A first turning parts, all specifications is Noah abutment rib 31a are in the same relative position, in fact, may be excluded even the operation of step S45.

Then will be described the operation of switching the transmission of motion in the recovery position C of the head with reference to Fig. The operation of switching the transmission of motion to the position C of the recovery head is essentially the same as the operation of switching the transmission of motion to position B to the filing, and the only difference is that the rotation direction and the rotation angle gear motor 63 of the cassette is changed. Only the operation different from the operation of switching the transmission of motion to position B to the filing, to be described below. Although the gear motor 63 of the cassette is rotated in the direction of rotation in step S43, gear motor 63 of the cassette rotates in the left direction of rotation in step S53. At step S53, when the encoder 106 of the provisions of the chain drive determines that the planetary arm 23 is in contact with the second rotary support rib 31b, and gear motor 63 of the cassette is stopped, the gear motor 63 of the cartridge stops. This operation is an operation in the initial state of the position of rotation of the planetary arm 23, that is, the rotation position of the planetary gear 22, the second swivel support ribs 31b.

Although the gear motor 63 ka the sets was rotated at a certain angle in the left direction of rotation in step S45, gear motor 63 of the cassette is rotated at a given angle in the direction of rotation in step S55. The given angle is the rotation angle, which is calculated on the basis of the angle of rotation required to achieve the planetary lever 23 to the position C of the recovery head from the second swivel support ribs 31b.

The above is the difference between the switching operation of the transmission in position B supply and the switching operation of the transmission traffic in the recovery position C of the head, which is in the direction of rotation and angle of rotation of the gear motor 63 of the cartridge. Then will be described switching operation of the transmission to position D supply in the cassette. The switching operation of the transmission to position D feed cassette is essentially the same as the operation of switching the transmission of motion in the recovery position C of the head, and only the different operation will be described.

By changing the angle of rotation during the rotation of the gear motor 63 of the cassette in the direction of rotation in step S55, the planetary arm 23 is rotated to move in a regulation D filing in the cassette. Operations other than the operation at the step S55 are the same as the operation of switching the transmission of motion to position C recovery goals is I. As described above, since the position D of the feed cassette is identical to the position in which the planetary arm 23 is moved to enter into contact with the second rotary support rib 31b, in fact, may be excluded even the operation of step S55.

As described above, when the operation of switching the transmission into the neutral position A or position B of the filing of the planetary arm 23 is moved to enter into contact with the first rotary abutment rib 31a, thus setting in the initial state, the position of rotation of the planetary arm 23. On the other hand, when the operation of switching the transmission of motion to the position C of the recovery head or the position B of the feed cassette of the planetary arm 23 is moved to enter into contact with the second rotary support rib 31b, thus setting in the initial state, the position of rotation of the planetary arm 23.

As shown in figure 5, the arrow 34a shows the path of the planetary lever 23, when the position of rotation of the planetary arm 23 was established in its original state using only the first rotary abutment rib 31a during operation, the gear shift movement from position B supply in regulation D filing in the cassette. On the other hand, the arrow 34b shows the movement trajectory, when was the imp is changed to the setting to its original state using the second swivel support ribs 31b. Comparing the magnitude of the movement indicated by the arrows 34a and 34b, each other, the amount of movement indicated by arrow 34a, leads to a rotational movement corresponding to the four positions, while the amount of movement indicated by the arrow 34b, leads to a rotational movement corresponding to only two positions. Similarly, arrows 35a and 35b figure 6 indicate the corresponding values of the movement. Comparing corresponding values move with each other, it can be understood that in operation, the gear shift movement from position C recovery head in neutral position, A rotational movement can be reduced to a minimum by means of forced entry into contact of the planetary arm 23 with the first rotary abutment rib 31a.

As you can see from above, through the operation of switching the transmission of motion by using a second swivel support ribs 31b, the amount of movement required to rotate the planetary lever 23 in operation, the gear shift movement, can be reduced in comparison with the switching operation of transmission using only the first swivel support ribs 31a. In addition, through the operation of switching the transmission of motion using the second rotary is about supporting ribs 31b switching operation of the transmission in position C of the recovery head can be simplified, and the time used to perform the operation of switching the transmission of motion to the position C of the recovery head may be reduced.

As described in the steps S43 and S53, the contact state of the planetary arm 23 during rotation is determined based on the stop gear motor 63 of the cassette, which is the source of movement. Thanks to such design, the angular position of the planetary arm 23 can be precisely defined, and therefore do not need to install an additional sensor for detecting the position of rotation of the planetary arm 23. In addition, the number of operations of the switching movement can be accomplished by determining the angle of rotation of the gear motor 63 of the tape and stop the gear motor 63 of the cassette in the contact state.

If the position of the planetary gear 22 before performing the operation, the gear shift movement is certain, the time required to complete the operation, the gear shift motion can be further reduced by actuation as follows. In the case of the operation of switching the transmission of motion from the neutral position A to the position C of the recovery head, the second swivel support rib 31b is located closer to the position C to reset the setting head, which is the position of the destination than to the first rotary abutment rib 31a. However, in this case, the time can be reduced by running setup in the initial state of the position of rotation of the planetary arm 23 with the first swivel support ribs 31a.

As shown by the arrow 33a in figure 4, it is necessary that the planetary arm 23 performed a rotational movement corresponding to the four positions when installation has been performed in its original state through forced entry into contact of the planetary arm 23 with the second swivel support rib 31b. On the other hand, as indicated by the arrow 33b, it is necessary that the planetary arm 23 performed a rotational movement corresponding to only two positions when installation has been performed in its original state through forced entry into contact of the planetary arm 23 with the first rotary abutment rib 31a. In addition, as indicated by the arrows 36a and 36b figure 7, the time can be reduced similarly in the case of the operation of switching the transmission of motion from position D feed cassette in position B supply. That is, in this case, the angle of rotation of the planetary arm 23 can be reduced by forced entry into contact of the planetary arm 23 with the second swivel support child who Ohm 31b.

In addition, the planetary lever 23 is rotated in the right direction and the left direction while maintaining the state of free rotation of the planetary arm 23. That is, the operation of rotation of the planetary arm 23 in the right direction for entering into contact with the first rotary abutment rib 31a and the operation of the rotation of the planetary arm 23 in the left direction of rotation for entering into contact with the second rotary support rib 31b are executed sequentially.

As described above, the mechanism 2, the gear shift movement is controlled by the circuit 100 controls to force sequential occurrences in contact with the planetary arm 23 with the first and second swivel support ribs 31a and 31b. The circuit 100 control determines the angle of rotation of the planetary arm 23, pivoted from the first rotary abutment rib 31a to the second swivel support rib 31b, through the use of encoder 106 provisions of the chain drive. Then the angle defined by the code sensor 106 provisions of the chain drive is compared with the angle of rotation required to rotate, which is determined by the structural layout elements and is stored in ROM. Based on the results of the comparison, the determination may be made in respect of what is correctly set in motion IU is aNISM 2, the gear shift movement, properly, there are two swivel support ribs 31a and 31b and correctly set in motion the carriage 73.

As described above, in this embodiment, the first and second rotary abutment rib 31a and 31b are provided for the installation to its original state, the rotation position of the planetary gear 22, and the ribs 31a and 31b are used selectively for contact with the planetary lever 23. Specifically, the planetary arm 23 can be rotated in the two types of operations, one operation, in which the planetary arm 23 is first moved from the existing provisions for entering into contact with the first rotary abutment rib 31a and then rotated to the target position, another operation, in which the planetary arm 23 is first moved to enter into contact with the second rotary support rib 31b and then rotated to the target position. The circuit 100 management selects and performs one of the actions listed above to move the planetary arm 23, which is rotated from an existing position to the target position, so that the selected operation requires that the planetary arm 23 is turned to a smaller angle. By management, thus, the time required to complete mechanism 2, the gear shift movement operation, the gear shift motion can be reduced is prohibited, and reliability of the mechanism 2, the gear shift motion can be improved.

The second example implementation

Then will be described a second embodiment with reference to Fig and 17. Fig depicts the precedence diagram for describing the operation of the gear shift movement in the position B of the submission, in accordance with the second exemplary embodiment, and Fig depicts a view illustrating a state in which the movement of the planetary gear 22 is excluded in mechanism 2, the gear shift movement.

The design of the inkjet recording device 1 and mechanism 2, the gear shift movement is similar to the construction of the first embodiment. Operations in steps S41-S45, illustrated in Fig similar to the operations in the steps S61-S65, illustrated in Fig. The difference between the first embodiment and the second embodiment lies in the operations in the steps S71-S79 on Fig, therefore, only different operations will be described, and descriptions of the same operations will be omitted.

As illustrated in step S71 on Fig, the carriage 73 is first moved to the ready position. The ready position is located between the first position 73a carriage 73 in a state of free rotation, as illustrated in Fig, and a second position 73c carriage 73 in the state is limited to the first rotation as illustrated in Fig, and corresponds to the third position 73b, as illustrated in Fig and 17. The state in which the carriage 73 is located in the third position 73b, will be called the state of readiness of rotation. As illustrated in Fig, when the carriage 73 is in the position 73b readiness, movement of the lever 27a the clutch housing is limited in the state in which the planetary gear 22 and sun gear 21 is not able to hold on to each other, and engage partially in the thickness direction of the gears.

The carriage 73 performs the function node for switching the state of rotation, as described above, and the lever 27a casing couplings tightened position, in which it comes in contact with the carriage 73 under the action of buoyancy force of the spring 28 and the clutch housing. When the planetary gear 22 is moved in the axial direction to enter in contact with sun gear 21, and the output coupler 26a and the input clutch 26b are detached from each other and are not able to take the torque of the driving force (step S71).

Two States can occur in the result of the operation at the step S71. As described above, when the planetary gear 22 was able to engage with the sun gear 21 as a result of moving in the axial direction at the step S71, the lever 27a the clutch housing will follow the movement of the carriage 73, as proil utrirovanno on Fig. When the pushing force of the spring 28 of the housing of the clutch causes the lever 27a the clutch housing to come into contact with the supporting part of the carriage 73 which is movable element (step S73).

If the planetary gear 22 is not able to engage with the sun gear 21, and the side surfaces of the teeth of the planetary gears 22 are in engagement with the side surfaces of the teeth of the sun gear 21 at the step S71, the lever 27a the clutch housing does not follow the movement of the carriage 73, as illustrated in Fig. Then the lever 27a the clutch housing is detached from the supporting parts of the carriage 73. When the pushing force of the spring 28 and the clutch housing is attached to the supporting portions of the inclined side surfaces of the respective teeth of the planetary gear 22 and sun gear 21. Since the frictional resistance between the inclined surfaces is large enough, the buoyancy force and the friction force are balanced state (step S75).

In the state in which the planetary gear 22 moves around the sun gear 21, a dead stroke chain drive extending from the gear motor 63 of the cassette to the sun gear 21, the planetary gear 22, the leading input gear 30 and the respective mechanisms appointments motion, equal to zero, as illustrated in Fig. The reason the state is t, what planetary gear 22 may have a dead stroke during the rotation, if dead stroke is not equal to zero, and, therefore, the mutual influence of teeth during its movement in the axial direction can be excluded due to the dead turn in the rotation. The state in which the planetary gear 22 moves around the sun gear 21 so that the dead stroke becomes zero, can occur in the case in which the drive circuit is locked in the right direction of rotation, and the dead stroke becomes zero, and the case in which the drive circuit is locked in the left direction of rotation, and the dead stroke becomes zero. Fig illustrates the state in which the drive circuit is locked in the right direction.

After step S75 gear motor 63 of the cassette rotates in the left direction of rotation (phase set s76). The reason for rotation of the gear motor 63 of the cassette in the left rotation direction at this stage is the following. To perform the operation after the operation is complete, the gear shift movement in the position B of the feed gear motor 63 of the cassette rotates in the direction of rotation so that the pickup roller rotates. In this case, when the planetary gear 22 moves around the sun gear 21 in a state locked by the left rotation direction, dead stroke during rotation may occur in the circuit of the drive torque of the driving force in the direction of rotation during the next operation of the feeder. Therefore, the mutual influence between the teeth of the planetary gear 22 is eliminated, and the planetary gear 22 is moved in the axial direction for engagement with a sun gear 21.

On the other hand, as illustrated in Fig, when the planetary gear 22 moves around the sun gear 21 in a state locked in the right direction of rotation, the mutual influence between the teeth will not be excluded due to the torque of the driving force in the direction of rotation during the next operation of the feeder. The reason is that the state of movement of the planetary gear 22 and the sun gear 21 is due to the contact between the inclined side surfaces of the teeth. Therefore, even when the rotary motion in the direction of rotation was performed in this state, the leading input gear 30 can be rotated in a state in which the planetary gear 22 moves around the sun gear 21. Otherwise, the planetary gear 22 may be moved on the inclined lateral surfaces of the teeth against the buoyancy force of the spring 28 and the clutch housing, causing the planetary gear 22 can push the I back in the axial direction of the center of rotation. That is, when a rotational movement in the direction of rotation is performed in this state, may be any of the above conditions.

As rotational movement during operation of the feeder, which is performed after the operation is completed, the gear shift movement is in the direction of rotation, rotational movement on the stage set s76 during the switching of the transmission traffic set in the left direction of rotation. Through actuation thereby, when the planetary gear 22 is locked in the right direction of rotation, so that the dead stroke is equal to zero, dead stroke when rotation occurs in the planetary gear 22 due to the rotational motion in the left direction of rotation, which is performed during the operation of the switching movement. Therefore, as illustrated in Fig, the mutual influence between the teeth, when the planetary gear 22 is moved in the axial direction, can be excluded. The optimum angle of rotation necessary to eliminate the mutual influence equal to at least half of one gear tooth. The reason is that the mutual influence between the teeth may not occur at an angle corresponding to half of one gear tooth, or more.

On the other hand, when the planetary gear 22 for the lock in the left direction of rotation, so dead stroke becomes zero, since the operation of the feeder, which is performed after the operation is completed, the gear shift movement, is due to turn in the right direction of rotation, the mutual influence between the teeth of the planetary gear 22 can be excluded due to a turn in the right direction. In addition, in this case, since the rotation angle in the rotation direction corresponds to half of one tooth of the gear, it does not affect the drive chain on the back steps or mechanisms destination of transmission in which torque is transmitted driving force leading the input gear (stage set S74).

In addition, in a state in which the planetary gear 22 is moved along the side surfaces of the sun gear 21, as illustrated in step S75, the lever 27a the clutch housing and the carriage 73 disconnected from each other, as illustrated in Fig. After that, when the movement of the planetary gear 22 and the sun gear 21 is excluded at the stage set s76, the lever 27a the clutch housing comes in contact with the supporting parts of the carriage 73 under the action of buoyancy force of the spring 28 and the clutch housing, as illustrated in Fig. In this case, however, the body 27 of the clutch and the planetary gear 22 increase the speed under the action of buoyancy force of the spring 28 and the clutch housing, as is Areca 73 is in the position 73b readiness, the magnitude of the displacement is small enough. Therefore, the housing 27 of the coupling will be faced with the carriage 73 before accelerating to high speeds, so that the noise of the collision can be reduced. In addition, since the carriage 73 is stopped in the ready position by means of a belt 76, which is an elastic member, even when the Overdrive lever 27a the clutch housing facing the carriage 73, the impact of a crash can be amortized by the belt 76 of the carriage, thereby reducing the noise in the collision. On the other hand, when the planetary gear 22, which is made from a relatively hard material, is faced with a sun gear 21, as illustrated in Fig can easily be created relatively strong noise of the collision because they are both made of solid materials.

As described above, the direction of rotation of the rotational motion, which is performed during the operation of switching the transmission of motion is opposite to the direction of rotation of the rotational motion, which is performed after the operation of the switching movement. In addition, the rotation angle in the left direction of rotation is set to half of one tooth of the planetary gear 22. Thus, the impact on the destination of transmission can be reduced as much as possible, and the state of movement of the planetary gear 22 and the sun gear 21 can be reliably excluded. In addition, as illustrated in Fig and 17, because the mechanism 2, the gear shift movement geared against the carriage 73, located in the ready position, can be prevented the formation of noise in the collision.

As described above, in accordance with this embodiment, the sun gear 21 is rotated at a very small angle during the operation of switching the transmission of motion and then rotated in the direction opposite to the rotation direction of movement, which is performed after the operation of the switching movement. Therefore, the planetary gear 22 and sun gear 21 can completely hooked with each other, and mechanism 2, the gear shift of traffic moving during operation, the gear shift motion, may hold against the carriage 73. Therefore, in accordance with this example implementation noiseless switching operation of the transmission mechanism 2, the gear shift driving force and increase the reliability of operation of the switching movement can be ensured.

At step S72, the flow diagrams on Fig is determined, moves or not the planetary gear 22 and the sun gear 21. The transition can actually be defined through the use of Dutch is ka, drive motor 63 of the cassette can be controlled in different ways depending on the result of the determination. For example, the stage set S74 may be excluded, unless there is a state of movement.

At step S71, the flow diagrams on Fig carriage 73 is moved to the ready position. At this time, the planetary gear 22 engages with the sun gear 21 and the leading of the input gear 40 sheet feeder or lateral side of the planetary gear is in contact with the side of the sun gear 21 and the side of the leading input gear 40 of the planetary gear 22 rolling on the sun gear 21. On the stage set S74 gear motor 63 of the cassette is provided in such a rotation, the sun gear 21 rotates to transmit drive force through the planetary gear 22 on the leading of the input gear 40. At this time, if the planetary gear rolls on the sun gear 21, the rolling motion is obtained by rotating the sun gear 21, and the planetary gear 22 is moved for engagement with a sun gear 21. The lever 27A of the housing of the clutch, shifting together with the planetary gear 22, is again in contact with the carriage 73 (step S77). At step S78, the carriage 73 is moved so that the carriage 73 is separated from the lever 27A the clutch housing. As a result, the process is switched is it a stage of restriction of rotation and the feeding position of the sheet.

On the stage set S74 gear motor 63 of the tape is driven in the left direction in all cases without definitions, moves do the planetary gear 22 and the sun gear 21. If there is no sensor for detecting the state of movement, transition, if it occurs, can be eliminated by bringing the rotation of the gear motor 63 of the cassette in the left direction of rotation.
