Prior art

The invention relates to a device for ejection of a fluid medium, and more particularly to a flexible connecting printed circuit intended for a device for ejection of droplets of fluid. In the following description, considered the link connecting printed circuits and generators droplets of fluid.

An inkjet printer forms a printed image by printing a pattern of individual dots in a certain area of the matrix defined for the print media information. These places are visualized as small dots in a rectilinear matrix. Sometimes these places are called "places points", "points" or "picture elements (pixels). Thus, a printing operation can be viewed as filling in the picture of the locations of dots dots of ink.

Inkjet printers print dots, throwing very small droplets of ink on the print media information, and typically include a movable carriage for printing, which serves to support one or more cartridges for printing, each of which has nozzles for ejection of ink. Carriage print makes a reciprocating movement over the surface of the carrier printed information, and control of the nozzles is carried out with the software eject drops of ink at appropriate moments, vremeni team microcomputer or other control device, when this synchronization points causing droplets of the ink must correspond to the picture elements of the image in the printed image. Usually for each transition or passage of the carriage for printing prints multiple image elements. The specific mechanism of ejection of the ink inside the printhead may take many different forms, known to experts in the art, in particular, those forms, which uses a print head for a thermal or piezoelectric technology. For example, two previously known mechanism of ejection of ink under pressure is shown to belong to the owner of the rights to this application is the U.S. patent nos 5278584 and 4683481. In thermal system between the Board of nozzle holes and thin-film substrate is a layer of barrier for the ink containing the ink channels and the camera evaporation of the ink. Thin-film substrate typically includes a matrix of heating elements, such as thin-film resistors which are selectively powered to heat the ink inside the chambers evaporation. When heated from a nozzle associated with powered heating element, ejected ink droplet. Due to the electoral zapisywania heating elements while moving the printhead across the print media information droplets of ink release is conducted on the media being printed information in the form of a drawing, forming a desired image.

In some inkjet printers utilize a replaceable ink cartridge, remanufactured after the devastation, and due to the presence of such printers, there is a need for reliable electric device pairing between the print cartridge and the printer in which the cartridge is installed.

Detailed description

In the following detailed description and on the several drawings, the same elements are denoted by the same reference numbers.

Referring now to figure 1, note that here shown symbolically inkjet printer 114 to partially cut and removed from the door for front loading. This printer includes a casing or housing 115 and the motor 116 of the actuator carriage mounted on the chassis. An electric motor drives the belt 118 in the reciprocating movement when the drive motor reverses direction of rotation. Drive belt 118 is connected to the carriage 119 to print, which makes a reciprocating scanning in the transverse direction along the axis SA of the scan carriage from left to right and right to left. The carriage 119 to print contains one or more outwardly similar cartridges 11 for thermal inkjet located side by side. For example, one print cartridge contains black ink and the other has three chambers, containing the s bright red (Magenta), yellow and light blue (cyan) ink. Horizontal movement of the scanning carriage 119 to print is sent to guide 121 slip. At the rear of the carriage 119 is an encoder, not shown, the sensing strip 122 encoder position and outputs information about the location of the carriage 119 to print along the axis SA of the carriage.

The carriage 119 for printing includes a clamping carriage, which smoothly and accurately positions the cartridges 11 for printing on the system of rectangular coordinates, shown in figure 2 and 10. The X-axis parallel to the axis of the scanning carriage. The Y-axis parallel and opposite direction to the path of advancement of the paper, which appears, for example, horizontally from the printer 114, so that the X-axis and Y define the horizontal plane. The Z axis runs vertically and perpendicular to the XY plane.

Referring now to figure 2-4, we note specifically that the cartridge 11 includes the body of the print cartridge containing a back wall 24, a left side wall 25, a right side wall 26, front wall 27 and bottom wall 28, which includes a protruding section 28a which serves as the backbone of the print head 15 for inkjet printing. To the upper edges of the front, side and rear walls connected to the top wall or cover 31, which includes a marginal ledges or edges 29, which extend beyond the lane the days and the side walls. On the cover 31 is close to the top of the rear wall 24 is a locking latch or part 50. The locking part 50 passes upward from the upper wall 31 and includes a front locking surface 50A and going back surface 50C, which crosses the top of the front fixing surface 50A of the edge surface 50b. As an illustrative example, the front fixing surface 50A is shown perpendicular to the cover 31, while extending back surface 50 C is an inclined surface, passes downwards and backwards from the top of the front fixing surface 50A. In an alternative embodiment of the invention, as shown in figure 3, passing back surface of the fixing part may include a horizontal surface 50C'. As described below, on the upper part of the fixing part 50 hits the latch. Depending on the application, this upper part is the edge surface 50b or horizontal surface 50C'.

In the immediate vicinity of the intersection of the left side wall 25, a back wall 24 and protrusion 28a are base RH the X-axis of the cartridge with the print head, the first base PY1 Y-axis of the cartridge with the print head and the first base PZ1 Z-axis of the cartridge with the print head. In the immediate vicinity of the intersection of the right side wall 26, rear wall 24 and the high energy of the UPA 28a are second base PY2 Y-axis of the cartridge with the print head and the second base PZ2 Z-axis of the cartridge with the print head. Third base PY3 Y-axis of the cartridge with the print head is in the upper part of the rear wall 24. Base Y-axis of the cartridge with the print head in General are a site whose configuration is such that they are essentially perpendicular to the Y-axis when the carriage 119 print cartridge. Base Z-axis of the cartridge with the print head are ground, the configuration of which is such that they are essentially perpendicular to the Z-axis when the carriage 119 to print set the print cartridge. The base of the X-axis of the cartridge is a site whose configuration is such that the base is essentially perpendicular to the axis X, when the carriage 119 to print set the print cartridge. As described below, the base of the cartridge interacts with the corresponding bases in the carriage.

On the rear wall 24 and the protruding section 28a of the lower wall 28 is a flexible printed circuit 33, which is wrapped around the intersection of these walls and provides the electrical connection between the printer and the print head 15.

Figure 5 presents a schematic detailed image of the flexible printed circuit 33, which includes a matrix of 70 pads 71, which give a possibility of contact interaction of the proximal side of the flexible printed circuit 33, which is the side facing the body of the cartridge. The hundred and the ONU flexible printed circuits 33, located at the base of the cartridge, called the far side. Pads 71 are located on the part of the flexible circuit 33, which is located on the rear wall 24, and contain conductive pads, which are made with the possibility of contact with the corresponding contact bar pins 139 on the elastic contact scheme 137 (Fig)located on the carriage 119 to print (figure 1). As an illustrative example, we note that the flexible printed circuit includes a flexible substrate, such as polyimide, on the far side of which is formed the conductive structure, the substrate has holes, so that the parts of the conductive patterns possible contact with the proximal side of the flexible printed circuit. In this embodiment, contact pads 71 are conductive pad, the open holes in the flexible substrate. Pads 71 may be round, octagonal, square with rounded or beveled corners, or may have any other shape.

In particular, pads 71 are many located side by side and separated in the transverse direction of the matrix-column 73 of the pads 71. Each matrix column 73 includes a lower contact pad which is closest to the bottom wall of the cartridge for printing, and that is also denoted by reference number 71' to facilitate reference to it. As an illustrative example, we note that the matrix-columns 73 may be essentially linear. In turn, the matrix-columns 73 are located side by side in pairs or groups 75A, 75b, 75s matrix-columns 73. As shown in the drawing, there are three pairs 75A, 75b, 75s matrix-columns 73 that allows you to have six matrix-columns 73 pads. Pair 75A, 75s matrix-columns 73 are external pairs, then as a pair 75b matrix-column 73 is a domestic couple. Each pair of matrices-includes two columns of the matrix column-73, which diverge toward the bottom wall of the cartridge.

Matrix-columns at the outside and the most remote from each other in the transverse direction, also denoted by reference number 73' for ease of reference. Such extreme outside and the most remote from each other in the transverse direction of the matrix-columns 73' may have fewer pads 71 than matrix-columns 73 located between the most remote from each other in the transverse direction of the matrix columns. As an illustrative example, we note that each of the extreme outside of the matrix-column 73' includes five pads 71, and each of the other matrix-columns 73 includes at least six pads 71. In the specific example shown in figure 5, the matrix-column 7, near one extreme outside the matrix-column 73'includes six pads, whereas each of the other matrix-columns 73 between the extreme outside matrices 73' includes seven pads. In addition, the extreme outside and the most remote from each other in the transverse direction of the matrix-columns 73' may have more contact pads 71 than matrix-columns 73 located between such extreme outside and the most remote from each other in the transverse direction of the matrix columns. In addition, the extreme outside and the most remote from each other in the transverse direction of the matrix columns 73' may have the same number of pads 71, as matrix-columns 73 located between such extreme outside and the most remote from each other in the transverse direction of the matrix columns.

Each matrix column 73 extends at least 70% of the height H of the smallest rectangle R, which covers the matrix of pads 71 and limits the area occupied by contact pads 71. Height H is essentially vertical. As a concrete example, note that the smallest rectangle R has a height H in the range from about 10 to 14 millimeters and a width W in the range from about 15 to 18 millimeters. The ratio of height to width may be in the range of the Colo 0.6 to about 0.9.

Pads 71 extreme outside and most distant from each other in the transverse direction of the matrix-column 73' may have a center-to-center distance, for example, about 2 mm from the adjacent pads in their matrix-column. Pads 71 extreme outside and most distant from each other in the transverse direction of the matrix-column 73' may also have center-to-center distance less than or greater than approximately 2 mm from the adjacent pads in their matrix-column. Pads 71 of the rest of the matrix-column 73 may have a center-to-center distance, for example, not less than about 1.7 mm from the other pads in their matrix-column. Alternatively, contact pads 71 of the rest of the matrix-column 73 may have a center-to-center distance, less than about 1.7 mm from the other pads in their matrix-column. Contact pad 71 in any matrix, the column may have a center-to-center distance, for example, not less than about 1.7 mm from the other sites in the adjacent matrix column. In addition, the contact area 71 in any matrix, the column may have a center-to-center distance that is less than about 1.7 mm from the other sites in the adjacent matrix column. The bottom contact pads 71' mosenifar matrix-columns 73 can be separated center-to-center distance, at least about 2.8 mm. In an alternative embodiment, the bottom contact pads 71' adjacent pairs of matrix columns 73 can be separated center-to-center distance that is less than about 2.8 mm. The bottom contact pads 71' matrix-columns 73 located between the extreme outside and the most remote from each other in the transverse direction matrix columns 73'may be located further from the bottom wall than the bottom contact pads 71' extreme outside and most distant from each other in the transverse direction of the matrix-column 73'. In an alternative embodiment, the bottom contact pads 71' can be at the same distance from the bottom wall or they can be at different distances from the bottom wall.

Depending on implementation, some or all of the contact pads 71, 71' are electrically connected to the printhead conductive paths, indicated in General by the reference number 77. Conductive paths are preferably located on the far side of the flexible printed circuit 33, which is a party held by a housing of the cartridge, and lead to the bar conclusions 74 on the print head 15 (figure 4).

Figure 5 shows that the contact pads include contact pads P1-P16 choice elementary group, pads A1-A13 addressing, contact super the E1-E2 permissions the contact area of the TSR thermistor, the contact area ID bit identification and contact pads TG1, TG2, BG1, BG2 ground bus.

Each of the extreme outside and most distant from each other matrix-columns 73' may include a contact pad (TG1, TG2) ground, whereas each of the matrix columns 73 internal pair 75b may include a contact pad (G1, G2) grounding. Pad G1 grounding in the matrix-column 73 of the inner pair 75b may be electrically connected to the contact pad TG1 ground in a near-far outside the matrix-column 73' through the grounding conductive paths 79, which runs close to the matrix columns, so it passes only the part of the flexible printed circuit, which is located on the rear wall of the housing of the cartridge for printing. Similarly, pad G2 grounding in the other matrix-column 73 of the inner pair 75b may be electrically connected to the contact pad TG2 ground in a near-far outside the matrix-column 73' through the grounding conductive paths 79, which runs close to the matrix columns, so it passes only the part of the flexible printed circuit, which is located on the rear wall of the housing of the cartridge for printing.

On figa shows a matrix of pads, analogues of the Naya fact, which are shown in figure 5, but with another strip of conductive paths 77 and pads TG1, TG2, G1, G2 ground connected to ground paths 79, located on the flexible printed circuit. More specifically, such a ground track may be laid close to the matrix columns, so that will be held only on the part of the flexible printed circuit, which is located on the rear wall of the housing of the cartridge for printing.

Figure 6 shows a matrix of pads similar to those shown in figure 5, but here are four pads, denoted by NC, are not used. In addition, the matrix pads, shown in Fig.6, includes twelve located in other places of the pads P1-R choice elementary group instead of sixteen. Pads TG1, TG2, BG1, BG2 grounding is electrically connected to the grounding paths 79, which lie close to the matrix columns, so are only on the part of the flexible printed circuit, which is located on the rear wall of the housing of the cartridge for printing.

Pads TG1, TG2, BG1, BG2 grounding flexible connecting printed circuits, shown in figure 5, 5A, 6, can be in different locations and can be connected to the conductive ground paths passing, for example, only the part of the flexible printing the schema, which is located on the rear wall of the housing of the cartridge for printing.

Referring now to Fig.7, we note that here the schematic view in plan of the print head 15, which you can use with flexible printed circuits shown in figure 5 and 5A. The printhead includes multiple generators 40 drops of ink, made in the form of a set of matrices column 61. Each matrix column consists of a number of elementary groups, so that all matrices are, for example, in the form of elementary groups PG1-PG16. Each generator of droplets of the ink is, for example, thermogenerator droplets of ink, consisting of a nozzle, the ink chamber, the heating resistor and the driving circuits. As an illustrative example, we note that the generators 40 of the ink droplets receive ink through slots 71 of the ink supply located next to the matrix columns 61 generators droplets of ink.

Generators droplets of ink in one of the elementary groups connected with the ability to switch in parallel to the corresponding select signal elementary group (Fig. 8, P(1-16)via an associated contact pad (P1-P16) selection of an elementary group of flexible printed circuits. One external matrix-column 61 contains basic groups PG1, PG3, PG5, PG7, while the other external matrix-column 61 contains a basic group PG10, PG2, PG14, PG16. One internal matrix-column includes elementary PG2, PG4, PG6, PG8, while the other inner matrix-column 61 contains a basic group, PG9, PG11, PG13, PG15.

On Fig presents, in particular, a simplified electrical block diagram illustrating the electrical connection provided by a flexible printed circuit 33 between the printer and the printhead. The printer includes a device 43 print management, with a current source excitation signal generator addressing and generator permissive signals. The current source excitation signal generator addressing and generator permissive signals serves the excitation current, the addressing signals and enable signals to the printhead via the contact bar conclusions 139 elastic contact circuit 137 (Fig), interacting with pads 71 of the flexible printed circuit 33.

In a specific example, the printhead having sixteen elementary groups PG1-PG16, sixteen denoted by the symbol P(1-16) separate excitation signals or signals of the choice of elementary groups, respectively, are issued through the pads P1-P16 in elementary PG1-PG16. Thirteen separate signals A(1-13) addressing are issued through the pads A1-A13 addressing, and two permissive signal E(1-2) are issued through the pads E1-E2 allowed the I.

More specifically, regarding the electrical connections between the flexible printed circuit, shown in figure 5 or 5A, and the printhead shown in Fig.7, it can be noted that the pads P1, P3, P7, P5 selection of basic groups in internal pair of 75s matrix-column electrically connected to an external elementary groups G1, G3, G7, G5. Pads P10, R, R, P16 choice of elementary groups in the outer pair 75A matrix-column electrically connected to an external elementary groups G10, G12, G14, G16. Pads P2, P4, P9, P11 in the outer pair 75A are connected to the internal elementary groups PG2, PG4, PG9, PG11. Pads P6, P8, P13, R selection of basic groups in internal pair 75b matrix-columns electrically connected to the internal elementary groups G6, G8, G13, G15.

Referring now to figure 9, note that here presents a schematic top view of the print head 15, which you can use with flexible printed circuit shown in Fig. 6. The printhead includes multiple generators 40 drops of ink, made in the form of three matrices-column 61. Each matrix column consists of a number of elementary groups, so that all matrices are, for example, in the form of elementary groups PG1-PG12. Each generator of droplets of the ink is, for example, thermogenerator Capel is to ink, consisting of a nozzle, the ink chamber, the heating resistor and the driving circuits. As an illustrative example, we note that the generators 40 of the ink droplets receive ink through slots 71 of the ink supply located next to the matrix columns 61 generators droplets of ink.

Printhead shown in Fig.9, electrically connected to the printer via a flexible printed circuit, shown in Fig.6, the same as that shown and described in connection with Fig.7, but in the presence of the twelve signals R(1-12) select elementary groups for elementary groups G1-PG12.

Thus, the generators of the droplets of ink in one of the elementary groups (PG1-PG12) is connected with the ability to switch in parallel to the corresponding signal R(1-12) select elementary group through an associated contact pad (P1-12) selection of elementary group flexible printed circuit shown in Fig.6. One external matrix-column 61 of the printhead shown in Fig.9, contains basic groups PG1-PG4, while the other external matrix-column 61 contains a basic group PG9-PG12. Internal matrix-column includes elementary group PG5-PG8.

More specifically, regarding the electrical connections between the flexible printed circuit, shown in Fig.6, and the printhead shown in Fig.9, it can be noted that the contact area is ADCI P1-P4 choice of elementary groups in the outer pair of 75s matrix-column electrically connected to an external elementary groups G1-G4. Pads P9-R choice of elementary groups in the outer pair 75A matrix-column electrically connected to an external elementary groups G9-G12. Pads P5, P6 selection of basic groups in the outer pair 75A are connected to the internal elementary groups G5, G6, while the pads P7, P8 selection of basic groups in internal pair 75b are connected to the internal elementary groups G7, G8.

Thus, in relation to flexible printed circuits, shown in figure 5, 5A and 6, and the print heads shown in Fig and 9, it is possible to draw a General conclusion that the first outer pair of matrix-columns of pads include pads choice of elementary groups, electrically connected with the first external set of elementary groups, the second outer pair of matrix-columns of pads include pads choice of elementary groups, electrically connected with the second set of external elementary groups and with a set of internal elementary groups, and the inner pair of matrix columns pads include pads of choice elementary groups electrically connected with another set of internal elementary groups.

Referring now to figure 10-17, note that, specifically, the carriage 119 for printing includes a base 126 serving time oparanozie, and two C-shaped supports 128 located at the ends of the base 126. These C-shaped bearing support 128 slidable carriage 119 to print located on the guide 121 slip. The carriage 119 to print also includes two tray 131, each of which is held and aligned the cartridge 11 for inkjet printing. Both trays are designed and work the same way. Each tray includes a back wall 135, which contains, for example, of the base 126, the left side wall 133 which projects from the rear wall 135, and the right side wall 134 which projects from the rear wall 135 and essentially parallel to the left side wall 133.

At the bottom of the tray 131 in the immediate vicinity of the intersection of the left side wall 133 and the rear wall 135 are base CY1, CZ1 and SH made, for example, in the form of the base 126, while at the bottom of the tray 131 in the immediate vicinity of the intersection of the right side wall 134 and the rear wall 135 are base CY2 and CZ2, made for example in the form of the base 126. On the back wall 135 is base CY3 carriage.

An elastic contact circuit 137 is located on the rear wall 135 of the tray and contains electrical contacts that rest against corresponding contacts on the flexible printed circuit 33 of the cartridge 11 to be printed. An elastic contact circuit 137 also functions as an elastic ale is NT which makes base PY1, PY2 the print cartridge to abut the base CY1, CY2 carriage when installing the cartridge 11. As an illustrative example, we note that the elastic contact circuit 137 includes a flexible printed circuit and a resilient cushion located between the flexible printed circuit and a back wall 135.

Near the right side wall 134 is moving spring 146, which are to offset the print cartridge from the right side wall 134 along the X-axis to the base RH cartridge to print conveniently engaged with the base SH carriage (as shown in Fig).

In each side wall 133, 134 has a profiled conduit 140. The guide channels 140 interact with the jaws 29 of the cover 31 of the cartridge 11 to print and send the cartridge with a suitable raising and tilting (or rotation) of the cartridge relative to the X-axis at the insertion of the cartridge to move the cartridge in common at the bases of the carriage. As an illustrative example, we note that each guide channel includes upper and lower rails 140A, 140b, or represents a profound gap with the appropriate parties.

Above the upper part of the front of the tray 131 posted by cross bar 179 (figure 10), which is located above the guide channels 140. This cross member prevents the insertion of the cartridge top,and prevents the expansion of the side walls in the case of attempts to push the cartridge is too low in the tray.

At the top of each tray 131 is a loop node 150 of the clamp (figure 10 and 14), including fixing the support arm 151 attached can be rotated by means of a hinge 153 to the top of the rear wall 135 with capability of hinge rotation about the axis of the hinge, which is parallel to the axis X. Locking the support arm 151 is essentially L-shaped, having a first shoulder a, which runs from the hinge 153, and the second arm 151b, which is essentially downward from the distal end of the first shoulder a. At the ends of the second arm 151b are locking hooks 155 to interact with locking straps 157 located on the front side walls 133, 134.

Turning deny the clamping lever 159 is attached to the lower side of the locking lever 151 by means of the hinge 161 pivoting of the clamping lever, which is offset from the hinge 153 locking lever and parallel to it, so it can be rotated about the axis of the hinge pivoting of the clamping lever, which is parallel to the axis X. the Clamping lever 159 passes essentially to the rear wall 135 of the tray when the latch is closed, and forms an acute angle with an imaginary line, which passes between the axis of the hinge locking lever and the axis of the hinge pivoting of the clamping lever. The clamping lever 159 is rejected by the spring 163, turning away from the locking lever is 151. Stops 165 located on each side of the clamping lever 159, limit the rotation of the guide arm in the direction from the locking lever 151.

At the distal part of the rotary clamping lever 159 is Playground 167 to push down the upper part (50b, 50C') of the fixing part 50 of the cartridge 11 to be printed. The site goes 167 continued 169, which prevents the jamming clamp 159 on the front locking surface 50 a of the fixing part 50.

Pivoting the clamping lever 159 also includes tracks 171, which are slidable sliding the clamping lever 173, moving essentially perpendicular to the axis of the hinge pivoting of the clamping lever. Sliding the clamping lever 173 is rejected by the spring 175, gliding along the pivoting of the clamping lever 159 in the direction of the hinge 161 swivel clip. The displacement of the sliding clamp 173 limit stops 175. At the distal end of the sliding clamp 173 is near the ground 167 pivoting of the clamping lever is Playground 177 moving the clamping lever.

In operation, the cartridge 11 is inserted essentially horizontally in the tray 131. The guide channels 140 regulate the elevation and tilt of the cartridge 11 relative to the X-axis as it is inserted into the tray 131, so that the base PY1, PY2 the print cartridge is moved in the appropriate databases SW, 2ND coaches is I. Then turn the locking lever 151 down, causing eventually the interaction site 177 moving the clamping lever and pad 167 pivoting of the clamping lever from the front fixing surface 50A and the upper part (50b, 50C') of the fixing part 50 on top of the cartridge. Continued movement of the locking lever 151 causes the sliding clamp 173 elastically pushed by the locking part being along the Y axis, and also to the fact that the rotary clip 159 is pushed by the locking part being along the z axis, Pushing, taking place essentially along the axis Y, does not depend on push taking place essentially along the z-axis Pushing occurring along the Z-axis, causing a comfortable fit bases PZ1, PZ2 cartridge for printing on base Z1, Z2 carriage. Pushing occurring along the Y axis causes rotation of the cartridge for printing with respect to an axis X, so that the base PY3 cartridge to print conveniently sits on the SS3 base of the carriage. An elastic contact circuit 137 is located, so that is a comfortable fit bases PY1, PY2 cartridge for printing on base SW, 2ND carriage when the PZ1, PZ2 cartridge for printing interact with databases Z1, Z2 carriage and base PY3 the print cartridge interacts with the SS3 base table.

The locking lever 151 is also shifted, bringing together the locking hooks 155 spikerushes straps 157, that ensures the provision of Playground 177 moving the clamping lever and pad 167 fixing of the clamping lever continuous pressure on the front surface 50A and the upper part (50b, 50C') of the fixing part 50 along the axes Y and Z, so that the base PY1, PY2, PY3, PZ1, PZ2 cartridge to print continuously interact with databases SW, 2ND, SS3, Z1, Z2 carriage.
