Abstract

PURPOSE:To surely prevent contamination in the vicinity of a place where toner is used, by providing a fixing member which can be fitted to the surrounding wall of the toner cartridge inserting port of the main body of a copying machine at the opening section of a bag made of a flexible thin film. CONSTITUTION:In order to set a toner cartridge 1 above a hopper 3 through the inserting port 10 of a machine body 9, the side edges 11 of a cartridge vessel 13 are inserted along guide grooves 12 and a fixing member 18 fitted to the opening section of a containing member 17 is then fixed to the machine body 9. Fixation of the fixing member 18 to the surrounding wall of the inserting port 10 is made by means of the pressure-fitting between a pin 19 provided on the machine body 9 and a hole 20 provided in the fixing member 18. After the toner cartridge 1 is fixed above the hopper 3 in such a way, a sealing member 16 covering the opening section is removed and the toner in the vessel 13 is dropped onto the hopper 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cartridge for replenishing toner used to develop a latent image, and more specifically, a technique for disposing a replenishing toner cartridge in an electrophotographic copying machine, etc. It is related to.

Prior Art Conventionally, replenishment toner cartridges have been used to replenish consumed toner in copying machines.
At this time, if the cartridge is configured to be placed on the copier hopper with its opening facing down, and then the opening seal is peeled off to allow the toner to fall into the hopper, pull the cartridge out of the copier for replacement. At times, there was a risk that residual toner adhering to the inner wall of the cartridge would fall and contaminate the surrounding area. In addition, we have improved this and made the cartridge 18
Even if the cartridge is rotatable by 0 degrees and the opening is directed upward when the cartridge is pulled out, there is a risk that the opening may be inadvertently turned downward and the toner may fall while the cartridge is being carried to be discarded.

The present invention is intended to eliminate the inconvenience caused by the stains generated around the device due to toner falling due to various reasons when toner cartridges are replaced.

U. In order to achieve the above object, the present invention attaches the bottom part of a flexible thin film bag large enough to accommodate a toner cartridge to the toner cartridge drawer handle attachment wall, and the opening at the other end is provided with a bag for a copying machine. The toner cartridge is characterized in that it is provided with a fixing member that can be attached to the peripheral wall of the toner cartridge insertion opening of the main body.

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 1 is a cross-sectional view of the developing section schematically showing a state where the toner cartridge 1 is set on the toner hopper 3 of the developing device 2 with the opening 4 facing downward, where 5 is an agitator, 6 is a developing roller, and 7 is a developing section. 8 is a doctor blade, and 8 is a photosensitive drum.

FIG. 2 shows that the toner cartridge 1 according to the present invention is inserted into the cartridge insertion slot 10 of the main body 9 of the copying machine, and
This is a perspective view showing a state in which the cartridge 1 is about to be positioned on the hopper 3 as shown, and the cartridge 1 is configured so that the side edge 11 of the cartridge is slidably guided in the guide groove 12 on the hopper and the cartridge 1 is stopped at a fixed position. ing.

By the way, the conventional cartridge has a container 13 for storing toner, a drawer handle 15 provided on the end wall 14 of the container, and an opening 4.
, and a sealing member 16 for sealing the opening 4. However, in the present invention, as shown in the figure, a flexible thin film packaging having a size that can accommodate the toner cartridge 1 is attached to the end wall 14 of the cartridge container 13. In addition to attaching the bottom of the housing member 17, two fixing members 18 and 18 are provided in the opening at the other end of the housing member, which can be attached to the peripheral wall of the toner cartridge insertion opening 10 of the copying machine body 9. There is.

The role of this fixing member 18.18 is to secure the opening of the flexible thin film housing member 17 and secure the toner cartridge 1 to the copying machine body 9.
This is to keep the used toner cartridge container 13 fixed to the machine body when it is pulled out, so that the used toner cartridge container 13 is wrapped in the flexible thin film packaging member 17, as shown in FIG. It does not have to be this, and may be any suitable one.

To set the toner cartridge 1 onto the hopper 3 from the insertion port 10 of the machine body 9, after inserting the side edge 11 of the cartridge container 13 along the guide groove 12,
The fixing member 18 attached to the opening part of the containing member 17 is fixed to the fuselage 9. In the embodiment shown in FIG. The pin 19 is press-fitted into a hole 20 provided in the fixing member 18.

After the toner cartridge 1 is fixed on the hopper in this manner, the seal member 16 covering the opening is peeled off, and the toner inside the container 13 is allowed to fall into the hopper 3.

Since the toner cartridge of the present invention is constructed as described above, when replacing the used toner cartridge 1, as shown in FIG. Therefore, the container 13 is taken out while being wrapped in the enclosing member 17. Furthermore, after the cartridge container 13 is completely extracted from the insertion port 10 and accommodated in the flexible thin film containing member 17 such as polyethylene, the fixing member 18
By removing the cartridge container 13 from the body 9 and tying the bottom of the fixing member 18 with a string or the like as shown in FIG. 4, the cartridge container 13 can be disposed of without fear of toner contamination.

In this embodiment, thin polyethylene is used for the packaging member 17, but other materials such as paper may also be used, and as shown in FIG. desirable.

As explained above, according to one aspect of the present invention, when replacing a toner cartridge, the used cartridge container 13 is automatically wrapped in the containing member 17 whose bottom portion is attached to the end wall of the container. It is possible to reliably prevent surrounding contamination due to falling toner remaining on the
Further, by tying the opening of the containing member 17 with a string or the like, it is possible to dispose of the containing member 17 without worrying about contamination with toner.
