Abstract

PURPOSE:To rapidly and surely feed toner to a developing part from a toner replenishing port without soiling the hands and the clothes of an operator by loading a toner cartridge in a device at the time of supplying the toner and operating a lever on a device main body side. CONSTITUTION:This device is provided with a replenishing cover opening/closing part 2 functioning as a rotary cover which opens/closes a replenishing cover for supplying the toner in the toner cartridge 1, a developing part 3 for printing on paper, an insertion guide 4 in the case of loading the toner cartridge, and a lever for supplying toner 5 which presses the part 2 at the time of loading the toner cartridge and opens the replenishing cover for supplying the toner. By pushing down the lever 5 in a state where the toner cartridge 1 is loaded so that the toner cartridge 1 is adjusted to the guide of the insertion guide 4, the part 2 is rotated at 90 deg. and becomes vertical, and the replenishing cover for supplying the toner, which is incorporated in the toner cartridge 1, is also rotated at 90 deg., whereby the replenishing cover is opened to supply the toner to the developing part 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toner replenishing device for a printer, and more particularly to a toner cartridge type toner replenishing device for a printer which is detachably mounted.

[0002]

2. Description of the Related Art Conventionally, a toner cartridge in a printer using toner has a toner filled in the cartridge, a replenishing port is sealed with a nylon film, and the toner is pulled out to replenish the toner to a developing section. It was supposed to do.

[0003]

Therefore, when the toner cartridge is replenished with the toner cartridge of the conventional printer apparatus as described above, the seal of the replenishing port of the toner cartridge is pulled out to replenish the toner. Toner adheres to a later seal, and the seal stains the operator's hands and clothes, and the dust and smoke of the toner rises to contaminate the device and the like.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a toner replenishing device for a printer, which is capable of improving the disadvantages of the conventional example and, in particular, capable of performing a toner replenishing work quickly and smoothly.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a printer having a cartridge for replenishing toner, which is detachably mounted on a developing portion of the printer body, and an insertion guide for guiding the mounting of the cartridge is provided in the printer body. In the toner replenishing device for toner, a replenishing lid of the cartridge is a rotary opening / closing type rotary lid, and a replenishing lever for urging a rotational force to the rotary lid is provided in the printer body. This aims to achieve the above-mentioned object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a side view showing a state before mounting a toner cartridge in a main part of an embodiment of the present invention, and FIG. 2 is a side view showing a state after mounting a toner cartridge in a main part of the embodiment. Is.

FIG. 1 shows a toner cartridge 1 having a replenishing lid for supplying toner, a replenishing lid opening / closing portion 2 as a rotary lid for opening and closing the replenishing lid for supplying toner in the cartridge 1, and printing on a sheet. The developing unit 3 and the insertion guide 4 for mounting the toner cartridge 1 are provided. Further, it is configured to include a toner replenishing lever 5 that opens the replenishing lid that supplies toner by pressing the replenishing lid opening / closing portion 2 when mounted. Then, the printer device configured as described above supplies toner as follows.

That is, as shown in FIG. 1, before the toner cartridge 1 is mounted, when the replenishing lid opening / closing section 2 is horizontal, the replenishing lid for supplying the toner to the developing section 3 is closed. And toner cartridge 1
The toner cartridge 1 is attached according to the guide of the insertion guide 4. In this state, since the replenishment lid built in the toner cartridge 1 for supplying toner is still in the closed state, the toner is not supplied to the developing unit 3 and printing cannot be performed.

Next, as shown in FIG. 2, the toner replenishing lever 5 is pushed downward while the toner cartridge 1 is mounted with the toner cartridge 1 aligned with the guide of the insertion guide 4. Rotates 90 degrees and becomes vertical, and the replenishing lid built in the toner cartridge 1 for supplying toner also rotates 90 degrees and the replenishing lid opens,
By supplying the toner to the developing unit 3, printing is performed on the paper.

[0011]

As described above, according to the present invention,
Attach the toner cartridge to the device when replenishing toner,
To provide an unprecedented excellent toner replenishing device for a printer in which toner can be quickly and reliably fed to a developing unit from a toner replenishing port without operating an operator's hand or clothing by operating a lever on a main body of the device. You can
