Abstract

PURPOSE:To prevent contamination of an operator's hand and clothing at the time of replenishment by providing a replenishing cap which slides and opens on the replenishing port of a toner cartridge, aligning the replenishing cap to the guide pin of a developing part and operating a replenishing lever of the developing part to replenish the toner. CONSTITUTION:The slidable cap 2 is provided on the replenishing port of the toner cartridge, while the rotary type lever 6 for toner replenishment to open the cap 2 is provided on a device body side. The operator mounts the cartridge 1 by aligning the same to the insertion guide 4 of the developing part 3 and operates the lever 6 of the part 3 by aligning the cap 2 of the cartridge 1 to the guide pin 5 of the part 3. The cap 2 is then slid and opened and the toner in the cartridge 1 is replenished in the part 3. The cartridge 1 is correctly set in the replenishing port of the tank by the guide 4. The replenishment of the toner from the replenishing port is thus executed by a lever operation without contaminating the operator's hand and clothing.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to toner replenishment for printers and copying machines that use toner, and particularly to the structure of a toner cartridge that does not stain hands or generate powder smoke.

[Conventional technology]

Conventionally, in this type of toner cartridge, toner is filled into the cartridge, the replenishment port is sealed with a nylon film, etc., and the toner is supplied to the developing section by pulling out the seal.

[Problem that the invention seeks to solve]

Therefore, in the conventional toner cartridge described above, when replenishing toner, the seal from the replenishment port of the cough toner cartridge is pulled out to replenish the toner. This has the disadvantage that the operator's hands and clothes may be soiled), and the toner powder fumes may contaminate the equipment, etc.

[Means for solving problems]

The toner cartridge replenishment method of the present invention includes a lid that slides into the replenishment port, an insertion guide that can be set correctly in the tank replenishment port that stores toner, a ninth guide pin that opens the replenishment port, and a rotation that opens the replenishment port. It has a toner replenishment lever.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a toner cartridge 1 and a supply lid 2 of the toner cartridge L. Developing section 3 and insertion guide 4 for the toner cartridge 1. It is composed of a guide bin 5 and a toner replenishment lever 6.

Install the toner cartridge 1 in alignment with the insertion guide 4 of the developing section 3, align the replenishment lid 2 of the toner cartridge 1 with the guide bin 5 of the developing section 3, and operate the replenishment lever 6t of the developing section 3. , 6, toner cartridge 1 and developing section 3 are supplied with toner.

〔Effect of the invention〕

As explained above, the present invention allows toner to be supplied from the toner replenishing port to the developing section without staining the operator's hands or clothes by installing a toner cartridge in the apparatus and operating a lever on the apparatus main body when replenishing toner. It has the effect of sending it to the
