イクロスイツチを使用することができなかつた。 Traditionally, residual toner removed from the photoreceptor during the cleaning process is stored in a collection container installed inside the copying machine, and when the container is filled with toner, the container is removed to be collected and disposed of. Ta. In this case, the amount of toner in the container must be detected by a detection means to notify when to replace the container.
Conventionally, the container was made of a transparent material, and the limit of the amount was detected by photoelectrically detecting the amount of toner inside the container, which could cause malfunctions if the inside of the container became dirty due to toner scattering. There was a problem. Furthermore, since this container was connected in a sealed manner to a collection pipe connected to a cleaning device, a normal micro switch could not be used.
本発明は上記従来の不具合を解消して確実にト

提供しようとするものである。 The present invention aims to solve the above-mentioned conventional problems and provide a toner collection device that can reliably detect the amount of toner.
以下その構成を図面に示した実施例に基づいて

ａよりボトル４内へ突出させてある。 In the figure, 1 is a photoreceptor of an electrophotographic copying machine, 2 is a cleaning device for removing residual toner adhering to the surface of the photoreceptor 1, and 3 is a collection pipe connected to the bottom of the cleaning device 2. The tip of this recovery pipe 3 is opened above the bolt 4. A bag 5 is inserted into the bolt 4 and has its opening removably connected to the collection pipe 3, and the bag 5 is made of a flexible material such as vinyl. A micro switch 6 is attached to the machine frame (not shown) of the copying machine near the opening end of the bolt 4, and its actuator 6a connects to a notch 4 formed in the opening edge of the bottle 4.
It is made to protrude into the bottle 4 from a.

で密閉し、移動する。 The collected toner from the cleaning device 2 is collected through the collection pipe 3 into the bag 5, and when this becomes full and the upper part of the bag 5 bulges, the actuator 6a of the micro switch 6 is activated at this part. Notifies that bag 5 is full of toner. After that, the bag 5 is removed from the recovery pipe 3 and its opening is closed, and the bottle 4 is taken out and the opening is placed on the underside of the bottle 4 and the lid 7 is closed.
Seal and move.

価なマイクロスイツチを使用できる。 The present invention is as described above, and includes a bag 5 which can be detachably attached to the tip of the collection pipe 3 connected to the cleaning device 2 and is made of a flexible material, and a detection means for detecting deformation of the bag 5. Since the toner recovery device for an electrophotographic copying machine is constructed, malfunction of the detection means due to toner scattering is eliminated, the amount of toner can be reliably detected, and an inexpensive micro switch can be used as the detection means.
