The engine 500 housing is installed in the casing 100 of the housing. The engine 500 body can produce a driving force and transmit it to block 440 of filing, if the container 400 for manifesting substances placed in the fixture 110 to the container. The engine 500 housing includes a source 510 of motion, which produces a driving force, and a gear housing 520, which transmits driving force from a source 510 of the movement. The configuration of the engine 500 housing may be variously modified, provided that it performs its function.

Gear housing 520 may have a configuration such as a gear, Cam, connecting rod, etc. for transmitting the driving force from the source 510 motion to the container 400 for manifesting substances. For example, Chester what I 520 chassis can be installed in one part of the device 110 to the container. When the container 400 for manifesting substances placed in the fixture 110 to the container gear 520 of the housing and the gear 441 container interlock with each other. Thus, the driving force from the source 510 motion is transmitted to the gear 441 container through the gear housing 520. The configuration of the gear housing 520 may be variously modified, provided that it performs its function.

Element 600 detection is preferably installed in the container 400 for manifesting substances. Element 600 detection can generate the detection signal by determining the remaining amount of the developer T matter in the container 400 for manifesting substances and to transmit the detection signal to the controller 700. Element 600 discovery may have different technologies for detecting the remaining quantity of the developer substances T.

For example, the element 600 detection can be performed as piezocrystal element mounted in the lower part of the casing 410 of the container, to determine the load manifesting substance T element 600 discovery. Alternatively, the element 600 detection can be performed as an optocoupler, which applies the principle of emission and reception of light for detecting the remaining quantity of the developer substances T.

Element 600 discovery may have another con is Horatio, which determines the electrostatic capacity. Two electrodes can be separately installed in the casing 410 of the container where it is stored manifesting substance T, and electrically connected to each other outside of the casing 410 of the container. In accordance with this manifesting substance T of a dielectric material is placed between the two electrodes, which are made in the form of capacity. When the amount of the developer T matter in the casing 410 of the container is changed, the total amount of electric charge from the capacitance also changes and can be detected element 600 detection and converted into a load manifesting substances T.

Element 600 discovery may have another configuration in which the upper part of the casing 410 of the container set point counter for calculating the number of manifesting substance T using the specified algorithm. Element 600 detection may have a different configuration inside or outside of the container 400 for manifesting substances, provided that it performs a function for detecting the remaining quantity of the developer substances T.

Element 600 detection preferably transmits a detection signal to the controller 700. Element 600 of detecting electrically connected with the contact part 430 of the container and transmits the detection signal to the controller 700, when the container DS manifesting substance is set on showing the device 300. Element 600 detection can detect the remaining amount of the developer T matter in a specified time (for example, when the device is turned on, periodically, pereodicheski, on the basis of commands or actions of the user) or in real time, without restriction.

The controller 700 may control the actuation of at least one element from a set consisting of block 440 supply and engine 500 of the housing, thereby ultimately controlling the actuation unit 440 feed. The controller 700 may control block 440 feed in various ways. For example, is switched on and off source 510 motion or blocked or permitted the transfer of driving force between the source 510 movement and the gear housing 520 to control unit 440 submission.

However, since the remaining amount of the developer T matter stored in the container 400 for manifesting substance, continuously decreases, the quantity supplied manifesting substance T respectively decreases gradually over time, based on the fact that the controller 700 operates block 440 feed during this same period of time and at the same speed. When manifesting substance T unevenly served in the displaying device 300, in the printed media may be formed of a defective image. Thus, the counter is ller 700 preferably controls the actuation unit 440 submission, in accordance with the remaining amount of the developer T matter in the container 400 for manifesting substances, in order to apply a uniform amount of manifesting substance T per unit time.

The controller 700 may receive the detection signal, which contains the information about the remaining amount of the developer T matter in the container 400 for manifesting substances from element 600 discovery. The controller 700 may increase the intensity of the work process in the unit of time to unit 440 filing, if the remaining amount of the developer substance T is less than the specified level. For example, the controller 700 can increase the intensity of the work process block 440 feed speed, slowly, gradually, etc. as reduced the remaining amount of the developer T matter in the container 400 for manifesting substance to the amount of the developer T matter per unit of time was uniform.

The intensity of the work process block 440 supply can be increased in various ways in accordance with various embodiments of the present General inventive concept.

For example, if the controller 700 turns unit 440 supply within a given unit of time for a single filing manifesting substance T, the ratio of time steps per unit time for a block 440, the feed may be increased in accordance with the remaining amount of the developer T matter in the container 400 for manifesting substances, is about as remaining amount decreases.

Alternatively, the speed of the block 440 supply can be increased while maintaining a constant relationship of time steps per unit time to block 440 feed. In this case, the speed of the block 440 supply is increased in accordance with the remaining amount of the developer T matter in the container 400 for manifesting substance, as the remaining amount of the developer T matter decreases.

Will now be described by way of the control device to form the image in accordance with a variant embodiment of the present General inventive concept. As shown in figure 4, a variant embodiment of the control method can be used in the device 1 to form the image shown in Fig.1-3, and will be described with its use. However, it does not mean that the variants of embodiment of a control method for a device for forming an image and present the General idea of the invention are limited in this way. In the control method in accordance with an illustrative alternative embodiment, shown in figure 4, the speed of the block 440 supply is constant.

The controller 700 turns unit 440 feed at a specified time during the unit of time for the filing of manifests substances T in the container 400 for manifesting substances to showing the device 300. About the circle of filing manifesting substance T can be performed within the unit of time and repeated, while device 1 is used to form the image.

If the loop feed manifesting substance T is started (step S100), the controller 700 may be powered unit 440 filing within the time specified for the filing of manifests substance T to manifesting device 300 (step S110). At this point can be determined remaining amount of the developer T matter in the container 400 for manifesting substances (for example, by element 600 detection) and transmitted to the controller device for forming an image, for example, the controller 700 (step S120).

The controller 700 may determine whether the remaining amount of the developer T matter transferred from element 600 of detection lower than the specified level, which is pre-installed in the controller 700 (step S130). If the remaining amount of the developer substance T is less than the predetermined level, the controller 700 may increase and save time actions unit 440 of feed per unit time (step S140). If the remaining amount of the developer substance T is not less than the predetermined level, the controller 700 does not change the ratio of time steps per unit time block 440 submission (step S150).

Thus, one cycle of the supply manifesting substance T terminates (step S160). When a specified condition is satisfied, for example, passes a specified time, can begin the next cycle supply manifesting substance T (step S100).

The controller 700 is preferably checks the assigned value of the ratio of time to time unit for unit 440 supply before powering unit 440 feed. For example, if in the previous cycle supply manifesting substance T time steps to block 440 feed was increased, the controller 700 operates block 440 submission, in accordance with the assigned (e.g., increased) by the value in the current loop supply manifesting substance T (for example, step S110).

Accordingly, the ratio of time steps per unit time for a block 440, the feed can be increased, when the remaining amount of the developer T matter in the container 400 for manifesting substance is reduced, and thereby the amount of the developer T matter during one cycle of the supply homogeneous manifesting substance T is maintained uniform (for example, essentially uniform) in each cycle.

If the duration of block 440 supply has not been changed in the previous cycle supply manifesting substance T, the controller 700 operates block 440 filing in the current loop supply manifesting substance T with the same time steps as in the previous cycle (for example, step S110).

Will detail ways embodiment with reference to experimental data, illustrating the improved or ravnomerno the th supply manifesting substance T within the time unit in the apparatus for forming an image in accordance with this General idea of the invention.

The unit of time, which is one cycle of the supply manifesting substance T, for example, is assumed to be four seconds. Block 440 supply is switched on and off to supply manifesting substance T within the unit of time (e.g., four seconds). The initial remaining amount of the developer T matter in the container 400 for manifesting substances set to 80,

However, in the apparatus for forming an image, the efficiency of feed manifesting substance from the container with developing substance to showing the device decreases over time. Since the apparatus for forming an image is repeatedly formed image on a printing medium, the remaining amount of the developer substance in the container for the developer substance is constantly decreasing. The number of exhibiting substances submitted to manifesting device, continuously decreases gradually when the engine is in the container for the developer substance is driven for a specified time.

Apparatus for forming an image of the prior art can detect the amount of developer substances in manifesting the device and powering the engine of the container for the developer substances within the specified time, if the number is outside the allowable p is edely. In accordance with this manifests the substance stored in the container for the developer substance is supplied to the displaying device.

Figure 5 is a graph for illustrating the dependency of the supplied amount of the developer T matter per unit time from the remaining amount of the developer T matter in the container 400 for manifesting substance as the cycle repeats feed apparatus for forming an image of the prior art. In this example, the block 440 feeder is driven with the same speed and for the same time steps per unit of time. As illustrated in figure 5, as the remaining amount of the developer substance T is reduced, the amount of the developer T matter supplied to the displaying device 300 is reduced.

Thus, for supplying a uniform amount of manifesting substance T within a unit time, the ratio of time to time unit for unit 440 filing may be stepwise increased in accordance with decrease of the remaining amount of the developer T matter in the container 400 for manifesting substances. The increase in time steps of block 440 feed and the amount of the developer T matter in accordance with decrease of the remaining amount of the developer substances T prolost iravani in the following table.

6 and 7 illustrate the data in the table in the form of a graph. 6 illustrates the change of the time unit 440 submission, in accordance with the change in the remaining amount of the developer T matter in the container 400 for manifesting substances. 7 is a graph to illustrate the changes in the number of exhibiting substance T supplied from the container 400 for manifesting substances to manifesting device 300, when the ratio of time to time unit for unit 440 supply changes, as illustrated in Fig.6.

As illustrated in the table, and 6 and 7, as the remaining amount of the developer T matter in the container 400 for manifesting substance is reduced, the time steps per time unit DL is a block 440, the feed speed is increased from 3.0 seconds to 3.5 seconds and 4.0 seconds. The amount of the developer T matter per unit time is kept constant at a level of approximately 0,33, the Graph of figure 5, which does not apply this General idea of the invention, illustrates a significant difference from chart 7, which uses this General idea of the invention.

Similarly, the remaining amount of the developer T matter in the container 400 for manifesting substances can be determined for each cycle of the supply (or each prescribed (for example, every third) cycle supply) manifesting substance T, and accordingly the intensity of the work process block 440 supply per unit time is gradually increased. Thus, the cycle of submission manifesting substance T or the amount of the developer T matter to manifesting device 300 per unit time can be maintained essentially uniform.

Meanwhile, if the new container for the developer substance is set on showing the device 300, as manifesting substance T in the container 400 for manifesting substances consumed, the controller 700 initializes the block 440 feed. For example, the spent container 400 for manifesting substances can be replaced by a new container 400 for manifesting substances, while 4.0 seconds appointed as a researcher is as valid time unit 440 supply to the spent container 400 for manifesting substances in accordance with the remaining amount of the developer T matter, as illustrated in the table. Replaced the container 400 for manifesting substance stores 80 g manifesting substance T, and in accordance with this, the controller 700 can initialize the block 440 submission time is 3.0 seconds. Then, the controller 700 operates block 440 filing for 3,0 seconds in the first round submission after replacing the container 400 for manifesting substance.

In the previous illustrative embodiment, the embodiment has been described by way of stepwise increase of the duration of the time unit for unit 440 feed. However, the remaining amount of the developer T matter in the container 400 for manifesting substances can be determined in real time for a gradual increase in time steps of block 440 submission, which will be described with reference to the above-mentioned experimental data.

Figure 5 illustrates that the amount of the developer T matter to showing the device 300 is significantly reduced, as decreases, the remaining amount of the developer T. substances, provided that the initial duration of block 440 supply is assumed equal to 3.0 seconds and the initial amount of the developer T matter in the container 400 for manifesting substance is assumed to be 80 g, the amount of manifesting substance T is started in order to decrease the time when the remaining amount of the developer substance T is less than 70,

As illustrated in Fig, the block 440 supply can be maintained equal to 3.0 seconds from the time when the remaining amount of the developer substance T is a full 80 g, until the time when the amount of the developer T matter begins to decrease. In this case, the element 600 of detecting continuously detects the remaining amount of the developer T matter, and duration of block 440 supply gradually increases in accordance with decrease of the remaining amount of the developer substances T. When the block 440 supply reaches of 4.0 seconds and becomes equal to the time unit, time unit 440 feed no longer increases. Thus, the block 440 supply per unit time is gradually increased, as illustrated in Fig, and accordingly the amount of the developer T matter to manifesting device 300 per unit time is maintained approximately uniform.

When the container 400 for manifesting substance, manifesting substance T which consumed is replaced by a new container 400 for manifesting substances, the controller 700 can initialize the block 440 feed per unit of time and control element 600 detect the Oia for detecting the remaining quantity of the developer substances T.

Element 600 detection preferably continuously detects the remaining amount of the developer substance T and transmits the result of detection to the controller 700. The controller 700 gradually increases the duration of block 440 submission, in accordance with the remaining amount of the developer T. substances Such intensity increasing time steps by the controller 700 is not limited, but may have a different design/configuration, provided that it performs its function. In one variant embodiment throughput serve to manifest the device can be operated with the control (for example, changing bandwidth/number of manifesting substances to the soil stack over time) to maintain essentially uniform rate of flow from the supply container to the developer substance to manifesting device, as the number expressing the substance in the container for the developer substance is reduced.

Illustrative devices and methods in accordance with this General idea of the invention, as described above, the number of exhibiting substance supplied from the container for the developer substance to showing the device per unit time is adjusted so that it was essentially uniform. In accordance with this fo is the formation of a defective image on a printing medium can be reduced or prevented. In addition, can be improved product reliability.

The moving section of the source side moves when the cartridge for supplying developer enters the main unit of the device in a position where the primary colour cartridge is installed in the main unit of the device for interrelated movement of the valve section for the source side from the position for prohibited supply of developer to the position for allowed supply of developer as a result of linkage with the working section of the receiving side of the moving section of the receiving side, whose movement is controlled by the control element in a state in which the working section of the receiving side lies in the working position.

EFFECT: design of a cartridge for supplying developer, a primary colour cartridge and an electrophotographic image formation device in which when the cartridge for supplying developer is extracted from the main unit of the device in a position where both the primary colour cartridge and the cartridge for supplying developer are installed in the main unit of the electrophotographic image formation device, loss of developer through holes for feeding the developer or through holes for receiving the developer can be prevented.
