Abstract

PURPOSE:To prevent decrease in image density owing to imperfect mounting of a cartridge by providing a projection to be superposed on the projection of a toner cartridge which has completed insertion into a toner box and roration to the inside of a door of a developing device. CONSTITUTION:A flat plate-shaped projection 10 of a cartridge 6 is positioned horizontally when the cartridge 6 is inserted into a toner box 5 and is rotated after the toner cartridge is exchanged for the purposed of replenishing a toner. On the other hand, a flat plate-shaped projection 11 is also provided to the inside of the door provided to the main unit of a copying machine. When the door is closed, the projections 10, 11 are horizontally superposed on each other and the slit 8 of the cartridge 6 coincides with the slit 9 of the toner box 5. The copying operation cannot be made unless the slits 8, 9 coincide thoroughly with each other and therefore the decrease in the image density of the copy owing to imperfect mounting of the cartridge 6 is thoroughly prevented.

低下するきいう欠点があった。The developing device of the prior art electrophotographic copying machine has a magnetic roll 1. as shown in FIG. It consists of a housing 4 that houses a blender 2, a mixer 6, etc., and a toner distributor 5 that supplies toner into this housing from above by gravity. A toner cartridge 6 is installed, and toner falling downward from a slit 8 of the toner cartridge is supplied to the nousing 4 via a dispense roll 7. Toner-2
When installing a toner cartridge into the round hole of the Tuxus round hole, remove the cover from the slit 8 of the toner cartridge filled with toner, insert it into the round hole with the slit facing upward to prevent toner from spilling, and then Next, the toner cartridge is rotated from the protrusion 10 to the end point (not shown), and the toner is caused to fall down the slit onto the dispense roll. However, some users may continue copying work without rotating the toner cartridge sufficiently until the toner cartridge stops rotating, and in such cases, the slit 8 of the toner cartridge does not face completely downward, so The slit in the toner cartridge and the slit 9 in the toner 2x round hole do not match perfectly, and the toner is completely drained from the toner cartridge. There was a drawback that the image density of the copy was reduced because it did not fall into the box.

An object of the present invention is to provide an electronic copying machine.

The present invention will be explained in more detail with reference to the drawings below. According to the present invention, when a toner cartridge is replaced in order to replenish toner in a copying operation using an electronic copying machine, and the toner cartridge is inserted into the toner mix 5 and rotated, as shown in FIG. , the flat protrusion 10 of the toner cartridge is in a horizontal state. On the other hand, a flat plate-like protrusion 11 is also provided inside the door on the developing device side of the copying machine main body, so that when the door is closed, the protrusion on the toner cartridge and the protrusion on the inside of the door are horizontally overlapped. ing.

0 and the protrusion 11 are superimposed in parallel, and the slit 8 of the toner cartridge faces directly below and coincides with the slit 10 of the toner mix (see FIG. 1). FIG. 60 is a cross-sectional view taken along the line X-X' in FIG. Therefore, even if an attempt is made to close the door, the door collides with the protrusion 11 on the inside of the door, making it impossible to close the door.Therefore, the user of the copying machine must be aware of the incomplete installation of the toner cartridge before starting copying again. , the protrusion of the toner cartridge can be rotated sufficiently until it becomes horizontal, and the slit of the toner cartridge can be perfectly aligned with the slit of the toner mix.
