Driven shaft a connected to the drive shaft 110A of the housing 111 of the developer cartridge (for example, through the engagement of one or more toothed wheels), thereby element 122 transportation of the toner receives the driving force.

According to a variant implementation of the element 122 transportation of the toner can receive the driving force, for example, from the developing roller 113 and/or roller 114 submission, formed in the housing 111 of the developing cartridge, through the transmission gear (not shown).

The storage device 130 is installed in the toner cartridge 120 for use in determining the status of the toner cartridge 120. The storage device 130 allows the transmission and/or reception of signals to and/or from the device 1 imaging to provide the capability to detect, for example, whether the toner cartridge 120 in the developing cartridge 110, toner, information and, associated with printing, etc.

Storage device 130 may be placed in such location as to be accessible from the surface of the toner cartridge 120, which is open outward from the housing 111 of the developing cartridge when the toner cartridge 120 is installed in the recess 117, so that the exchange of signals could be installed between the storage device 130 and the device 1 imaging.

For example, according to a variant implementation of the storage device 130 (or its implications for access) may be located on the surface of the rear end 120b of the toner cartridge 120, which is behind the front end 120A when installed in relation to the direction indicated by the arrow B1, while the rear end 120b is open inside the housing 111 of the developing cartridge when the toner cartridge 120 is properly installed in the recess 117.

Storage device 130 may include any number of conclusions 131, 132, 133 and 134, which can be configured, each with a specified length along the direction parallel to the direction of the arrow A1, and can be contacted with the contact (for example, number of contacts, each of which corresponds to one of the conclusions 131, 132, 133, 134, for brevity, together referred to as the pin 13)formed in the housing 10 of the device 1 imaging. The pin 13 may be formed along the direction parallel to the direction of the Oia, in which you are installing the developer cartridge 110, and may be, for example, a plate spring of a given length, which is in the casing 12.

According to a variant implementation of at least one of the many conclusions 131, 132, 133 and 134 can be made longer than the other. The longest output can be, for example, the grounding terminal.

Many conclusions 131, 132, 133 and 134 on figa and 3B are referred to below as the first-fourth conclusions. The first conclusion 131 can be used as the output voltage common collector (Vcc)to supply power, the second output 132 may be used as output data and/or control, the third conclusion 133 may be used as the output clock signal, to receive the clock signal and the fourth output 134 may be used as a grounding terminal. The fourth conclusion 134 may be longer than the other conclusions 131, 132 and 133 and can be placed under other conclusions 131, 132 and 133. The fourth conclusion 134 acts on the remaining conclusions 131, 132 and 133 in the direction indicated by the arrow A1, so that the first contact with the contact 13 which is fixed to the housing 10 of the device 1 imaging, when the developing cartridge 110 is installed.

According to a variant implementation of the inclined surface 135 may be performed by tilt in the direction is shown by arrows A1, to absorb the collision between the storage device 130 and the pin 13, when the developing cartridge 110 is installed in the housing 10 of the device 1 imaging, as shown in figv. Inclined surface 135 may act to reduce the collision between terminals 131, 132, 133, 134 and pin 13, when the developing cartridge 110 is installed.

When the developing cartridge 110 is installed in the housing 10 in the direction indicated by the arrow A1, the inclined surface 135 presses the contact 13, which may be, for example, a plate spring acting in the direction of the casing 12, so that the pin 13 is gradually retracted due to the slope of the inclined surface 135 before contacting with the pins 131, 132, 133 and 134.

Thus, the inclined surface 135 can be used to gradually push the pin 13 as the developing cartridge 110 is mounted in the housing 10 of the device 1 imaging. To this end inclined surface 135 can be placed to the storage device 130 relative to the direction of the arrow A1, so that the inclined surface 135 can press the contact 13 to the entry of findings 131, 132, 133 and 134 in contact with the contact 13.

When the developer cartridge 110 containing the toner cartridge 120 is inserted into the housing 10, in accordance with the above components is ukami storage device 130, located on the toner cartridge 120, generates an electrical connection with contact 13 and may transmit signals and/or receive signals from the device 1 imaging.

The process of replacing the developing device in the device 1 forming images according to a variant implementation of the present invention is illustrated with reference to figures 1-4.

When the toner cartridge 120 must be replaced, for example, when the toner is consumed, the user pulls out the developer cartridge 110 from the housing 12 in the direction indicated by the arrow A2, as shown in figure 1.

Then, the user pulls out the empty toner cartridge 120 in the direction indicated by the arrow B2, as shown in figa, and inserts a new toner cartridge 120 is filled with a supply of toner into the housing 111 of the developing cartridge along the recess 117 in the direction indicated by the arrow B1.

When the toner cartridge 120 is fully seated in the recess 117, the storage device 130 located on the rear end 120b of the toner cartridge 120, opens outwards from the housing 111 of the toner cartridge through the notch 117, as shown in figv. As shown in figure 4, the driven shaft a engages with the drive shaft 110A, thereby causing the element 122 transportation of toner.

The developer cartridge 110 installed a new toner cartridge Assembly 120 includes a housing 10 in the direction indicated by the your arrow A1 in figure 1, and installed in the casing 12 of the housing 10. Many conclusions 131, 132, 133 and 134 are parallel to the arrow A1, and are formed having a predetermined length, so that the storage device 130 establishes contact with the housing 10.

Many conclusions 131, 132, 133 and 134 are in contact with the contact 13, so that information relating to, for example, whether the toner cartridge 120, the amount of remaining toner or print information can be transmitted into the body 10 of the device 1 imaging.

According to a variant implementation of the replacement toner cartridge may be installed with the possibility of replacement in the developer cartridge when the removable toner cartridge includes a storage device that is accessible through the conclusion or conclusions that are on the surface of the open end of the toner cartridge, which remains open when the toner cartridge is installed in the developing device.
