Abstract

PURPOSE:To remove automatically the seal which closes the supply hole formed on the circumferential face of a cylindrical cartridge, by inserting the cartridge to the insertion part of a developing equipment with the seal stuck to the cartridge and peeling off the seal by the engagement between the seal and the peeling member in the insertion part side when the cartridge is rotated. CONSTITUTION:A cartridge main body 1 is inserted to an insertion part 5 of a developing equipment 4 with a supply hole 2 directed upward and is brought to a home position where the cartridge is brought into abutment on a stopper; and when the cartridge main body 1 is turned in the direction of an arrow (a) by a knob 11, an end part 31 of a seal 3 is engaged with an edge 61 of a peeling member 6 of the insertion part 5. When the cartridge main body 1 is turned furthermore, the seal 3 is peeled off gradually from an end part 5; and when the cartridge main body 1 is turned up to the last end part of the seal 3, the seal 3 is detached from the cartridge main body 1 and is recovered into a recorvering vessel 7. The cartridge main body 1 is turned at about 180 deg. continuously, and an internal toner T is dropped into the developing equipment by its own weight and is supplied.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for replenishing toner to a developing unit of an electronic copying machine.

Conventionally, this type of container has been in the shape of a bag, a cylinder, or a bottle. The toner is a fine powder and costs 69. Since it is necessary to keep out moisture and to be sufficiently protected from the outside for storage and transportation, the supply port is sufficiently sealed.

The bag-shaped thing is easy to handle because it can be bent freely.
Also, when removing the seal and replenishing toner into the developing device,
There is a risk of ζ being exposed to the outside.

A cylindrical container (hereinafter referred to as a cartridge) 1 is removed by peeling off a seal 3 at its supply port 2 in the generatrix direction.

After being pushed into the insertion part 8 of the developing device 7 as shown in FIG.

The toner is refilled by turning it approximately 180 degrees using the knob 4 at one end so that the replenishing port 2 faces downward and dropping the toner, which provides excellent operability.

However, since the seal is completely adhered with adhesive to keep the replenishment port airtight, there is a risk that when it is removed, the final part may not come off and may break.

Then, the remaining part of the sticker has to be removed by pinching the part of the prosthesis with toner on it with a pusher. Additionally, since the cartridge is held in the hand and the seal is removed, even if the seal is successfully removed, there is the inconvenience that the toner inside spills onto the outside.

This invention was modified in view of the poor operability of the cylindrical car (cylindrical car) of the 9th type, and the cartridge is inserted into the insertion part of the m imager until the seal is attached.

By automatically removing the seal, all of the above drawbacks are resolved.

The present invention is a means to achieve the above objectives.

The cartridge, which has a replenishment port formed by cutting a part of its peripheral surface in one direction, is inserted into the insertion part of the developing device with the replenishment port facing upward, and then rotated approximately 180 degrees to replenish toner with the supplementary f110 facing downward. In the developer supply device.

The developer replenishing device is characterized in that the seal sealing the replenishment port is peeled off and removed by engagement with a peeling member on the insertion portion side during the rotational operation.

The embodiment shown in the drawings will be explained in detail.

1 is a cylindrical cartridge body, 2 is a cartridge body 1
Supply port formed by cutting a part of the 0 peripheral surface in the generatrix direction, 6
is the supply port 2t - a seal to seal, 4 is the jAIll device, 5
6 is the cartridge insertion part provided for the development amount 4, and the pusher W5
A peeling member is attached to a part of the seal. Reference numeral 61 denotes an auxiliary attachment member added to one end of the seal 5 to ensure attachment to the peeling member 6, and 7 is a collection container for the peeled off seal 60, which can be freely inserted into and removed from the developing unit 4.

Insert the cartridge body 1 into the developing device 40 insertion section 5 through the replenishment port 2t.
- After inserting the cartridge with it facing upward as shown in FIG. 6
1 engages with the edge 61 of the peeling member 6 of the insertion portion 5. m
K1gI & then edge 61 causes 7-rule 6 to end s5
The seal 6 is gradually peeled off (see FIG. 114), and when it reaches the final end S of the seal 6 L9i1m, the seal 6 is removed from the cartridge body 1 and collected in the collection container 7 as shown in FIG.

Continue to move the cartridge body 1 to the predetermined position by approximately 180 degrees.
The toner is rotated and allowed to fall under its own weight into the toner Tt-a imager in the P3 section to be supplemented. The container 7 is pulled out at any time and the collected seals 6 are crushed.

As explained above, the present invention eliminates the trouble of manually removing the cartridge outside the A/L imager as in the past.
11 Just by inserting the needle into the imager and turning it, the seal is automatically pressed and the toner is replenished, so all the disadvantages of conventional replenishment, such as cocoon weight, are eliminated, and the 8L imager is replenished. is performed functionally and quickly.

Claims (1)

[Claims] (1) Insert the cartridge, which has a supply port formed by cutting a part of its circumferential surface in the generatrix direction, into the insertion section of the developing device with the supply port facing upward, and then rotate it approximately 180 degrees so that the supply port faces downward. In a developer replenishing device for replenishing toner, the seal sealing the replenishing port is peeled off and removed by engagement with a peeling member on the push-in part side during the rotation operation.
