The toner cartridge has a side opening, where the side cover is disposed, and a transmission device passing through the side opening. The toner cartridge is disposed in an electronic imaging device which is provided therein with a sliding rail, a moving piece, and an elastic member disposed between the sliding rail and the moving piece. The toner cartridge is installed into or unloaded from the electronic imaging device by sliding along the sliding rail. The side cover has a pushing portion located above the sliding rail for pushing the moving piece to move toward the elastic member in the process that the toner cartridge is unloaded from the electronic imaging device, so as to prevent the transmission device from being damaged by the moving piece, thereby extending the life time of the transmission device.

Abstract: A driving unit for a photo conductor drum cartridge is assembled with a shaft of the photo conductor drum cartridge, including a gear and a conducting plate mounted on the gear. The conducting plate is provided with an elastic arm and defines an imaginary axis parallel to the shaft. When the elastic arm of the conducting plate is perpendicular to the imaginary axis, a distance L is defined between a distal end of the elastic arm and the imaginary axis. The distance L is longer than or equal to a radius d of an annular groove portion of the shaft and shorter than a radius D of the shaft. By means of this design, the driving unit can be reusable and provide a convenient detachment of a photo conductor drum.

Abstract: A transmission device for a photo conductor drum includes a shell, a limiting apparatus mounted in the shell and having a through hole, and a transmission shaft which is coaxial with the through hole at a beginning position. When the transmission shaft is moved axially by an external force to a pressed position, the transmission shaft is inclinable relative to the through hole, and when the external force is released, an elastic member will force the transmission shaft to move back to the beginning position. As a result, while the photo conductor drum is put into a housing of a printer, the transmission shaft can connect a driving shaft without a help of a guider for enabling the photo conductor drum to rotate steady and smoothly.
