Abstract

PURPOSE:To facilitate supplementing operation and to prevent a toner from scattering to the environment by filling an elastic bag body with the toner, and providing a draw-out cord to this bag body and storing it in the cartridge of a cartridge case. CONSTITUTION:The toner cartridge 1 constituted by filling the elastic bag body 2 with a toner is stored in the toner cartridge storage part 6, and the draw-out cord 3 is led out of the cartridge storage part 6 at this time. Then, a cover body 7 is closed and a pointed member 10 provided in the cover body 7 strikes the bag body 2 constituting the toner cartridge 1 to break the bag body. Consequently, the charged toner is supplied to a toner bottle 4 and the broken bag body 11 is prevented by the draw-out cord 3 to fall in the toner bottle 4. Thus, the toner supplementing operation is facilitated and the toner is prevented from scattering to the environment.

Description

[Detailed Description of the Invention] The present invention relates to an electrophotographic copying machine, etc. (hereinafter simply referred to as a copying machine).
This is a toner cartridge for supplying toner to the developing device installed in the main body of the machine, and in particular, a toner cartridge that can easily supply toner to the developing device without staining the operator's hands or the copying machine when replenishing toner. It concerns cartridges.

Since the toner in the developing device decreases with the copying operation, it is necessary to replenish the toner.

Conventionally, toner is filled in a container whose opening is sealed with adhesive tape or the like to form a toner cartridge, and when replenishing toner into a developing device, the adhesive tape is peeled off to open the opening. Toner is supplied and replenished into the developing device through the opening.

However, when conventional toner cartridges are used, toner spills from the opening of the toner cartridge when replenishing toner, staining the operator's hands and the area around the copying machine, and when removing a used toner cartridge, the opening There were problems such as residual toner spilling out.

The present invention eliminates and improves these drawbacks of the prior art. By filling a stretchable bag with toner and providing a pull-out string to the bag, the operator's hand and copying machine can be easily used when replenishing toner. To provide a toner cartridge which can easily supply toner into a developing device without staining the surrounding area and can simplify the removal of a used toner cartridge.

The present invention will be described below based on an illustrated embodiment. The toner cartridge (1) of the present invention has elasticity as shown in FIG. A bag body (2) made of rubber, for example, which can be accommodated in a cartridge accommodating part of a cartridge case provided in the section, toner filled in this bag body (2), and an opening of this bag body (2). It consists of a drawer string (3) that is closed and has a certain length.

Then, the toner cartridge (1) is housed in the cartridge accommodating part (6) of the cartridge case (5) provided on the top of the toner bottle (4) of a copying machine as shown in FIG. Close the toner cartridge above (
By bursting the bag (2) constituting the toner cartridge (11), the toner in the toner cartridge (1) is transferred to the toner bottle (
4).

To explain in more detail, the above cartridge case (5
As shown in Figures 2 and 8, the cartridge accommodating part (6) of ) has one end fixed to the upper part with a hinge or the like for sealing the cartridge case (5), and the other end is provided so that it can be opened and closed in the vertical direction. a lid body (7), and a funnel-shaped slope formed at the bottom for supplying toner to the toner bottle (4) when the bag body (2) constituting the toner cartridge (1) is ruptured. The wall part (8) (91) is composed of a wall part (8) (91), and a lid part (7
) is provided with a sharp member α0 for hitting and bursting the bag (2) constituting the toner cartridge (1) when the toner cartridge (1) is closed.

Therefore, the toner cartridge (1) is accommodated in the cartridge accommodating section (6), and at that time, the pull-out string (8) is pulled out to the outside of the cartridge accommodating section (6), or any part of the lid body (7) is After fixing the pull-out string (8) to the lid body (wa), the sharp member 0Q attached to the inside of the lid body (7) is removed from the bag body (2) constituting the toner cartridge (1). hit it and burst it,
The toner filled in the toner cartridge (11) is supplied to the toner bottle (4), and the drawer string (8)
) prevents the ruptured bag αυ from falling into the toner bottle (4) as shown in FIG.

In this embodiment, the sharp member is provided inside the lid, but the invention is not limited to this. For example, a small hole may be formed in the side wall of the cartridge accommodating portion, and a sharp object such as a needle may be inserted through the hole. A similar effect can be obtained even if the toner cartridge is ruptured by a member.

Furthermore, the attachment of the drawer string (3) is not limited to the opening of the bag body (2) in terms of the position, but can be attached at any position.

The present invention has the following two configurations, and toner can be supplied into the toner bottle simply by storing the toner cartridge in the cartridge housing portion and closing the lid, so that the toner replenishment operation is extremely simplified. Moreover, after the lid is closed, the bag that makes up the toner cartridge is torn inside the cartridge accommodating section to supply toner. The operator's hands and the area around the copier do not get dirty.

In addition, the removal of the cartridge accommodating part of the torn bag is easy due to the action of the pull-out string, which eliminates the contamination caused by residual toner that tends to occur when removing a used toner cartridge as in the past. The practical effects of the present invention are significant.
