JPS5818658A - Developer supplementing device - Google Patents

Abstract

PURPOSE:To open a supplementation hole of the developer in a developing device, and to improve the operability of a developer supplementing device, by cutting a rail for a cover body covering the supplementation hole, and moving the cover body and thus opening the supplementation hole. CONSTITUTION:A cover body 3 covering a supplementation hole 2 is fixed to a cylindrical cartridge body 1 through a rail 4. This body is inserted into the cylindrical cartridge insertion opening of a developing body with the supplementation hole 2 up, and consequently a circumference of the coupling part of the rail part 4 with the cover body 3 is cut with a cutter at the insertion part. In this state, when the body 1 is rotated at 180 deg. by operating a knob 11, the cover body 3 is moved to the body 1 through the stopper of the cartridge insertion part and the cutter cuts the remaining rail 4 to from the supplementation hole 2 downwardly, thereby supplementing a developer into the developing device. This supplementation opening is carried out in the developing device to improve the operability of the developer supplementing device.

Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, Hinohashi's developer replenishment device has a bag-shaped, cylindrical or bottle-shaped container, and the toner used is fine powder.

Since moisture is averse, it is essential that the container is sufficiently sealed from the outside for storage and transportation. Since it folds freely, it is difficult to handle (<, and there is a risk of spilling the toner outside when the seal is removed and the toner is supplied to the developer IIKI).

For a typical cylindrical container (hereinafter referred to as ``car''), remove the seal that covers the refill port in the direction of the generatrix.

After inserting it into the insertion tube marked ***, use the knob at one end to
0 (B) Since the toner T is dropped and refilled with the replenishment port facing downward, it is easy to operate. Because it is glued, there is a risk that it will not come off until the final part when it is removed and may break in the middle.

Then, there is a problem in that the remaining part of the sticker has to be removed by pinching the part with toner on the back side with your fingers. In addition, since the seal is removed by holding the cartridge by hand, even if the seal is successfully removed, the toner inside may spill out to the outside. This was improved in response to the poor quality of the cartridge, especially by inserting the cartridge into the insertion section of the IA imager with the seal attached and automatically opening the replenishment port.

This solves all the problems mentioned above.

As a means of solving the above problems of the present vAFi, a part of the circumferential surface of the cylindrical cartridge main body 10 is cut away in the direction of the generatrix, and the toner supply port 2 is removed.
The lid plate 3 is fixed to the cartridge body 1 with seals 4, and the seals 4 are attached to the second to third portions around the four circumferences of the iI plate 3. This developer replenishing device is characterized in that the replenishing port 2 is opened by cutting the lid plate 6 with cutters 5 and 6 and moving the lid plate 6 along the circumferential direction of the cartridge main body 10.

Outside the developing device, open the replenishing port 2 as described above and insert the cartridge into the cartridge insertion portions 7 and 8 of the developing device with the refilling port 2 facing upward. You can replenish the toner T by turning it.

However, if the above-mentioned opening operation is performed externally, there is a risk of smearing the toner, so the seal must be cut as described above.

It would be more convenient if the cover plate was moved automatically within the developing device.

Therefore, the above-mentioned cartridge is directly inserted into the cartridge insertion portions 7 and 8 of the developing device with the replenishment port 2 facing upward, and at this time, the cutters 5 and 5a provided near the entrance of the insertion portion are inserted inward in the generatrix direction of the lid plate 4. The seal 4 is cut along the circumference in the generatrix direction.

After the cartridge 1 has been inserted to the set position, the cartridge is rotated in the direction a using the knob 11, and at this time, the seal 4 is cut at both front and rear ends of the cover plate 3 in the generatrix direction with cutters 6 provided in the push-in part. Then, the cover plate 3 is stopped by the stopper 81 provided on the insertion part 8 on the traveling side in the rotation direction (C Fig. 4), and only the cartridge main body is continued to be rotated to replenish the cartridge as shown in Fig. 5. By configuring the opening 2 to be positioned approximately downward, the opening of the replenishing port is performed inside the container, resulting in a developer replenishing device that is extremely easy to operate. 〇When depositing the cartridge from the developing device 1 in the opposite direction from the front, the cover plate 6 also returns from the position shown in Figure 85, and in that figure, the right end is the cutter 51 on the right.
When the cartridge is completely closed, only the cartridge body turns until the positioning protrusion 10 is on the left end of the cover plate 3, closing the supply port 2. In this state, the cartridge is taken out from the developing device 1.
Note that the cover plate 3 is provided with frame-shaped projections 5a and 3b to ensure that the seal 4 can hold the seal 4 and the cutter can cut the seal 09.
0 indicates the opening/closing guide rail of the cover plate 6 provided on the cartridge body 1;
