生じ易いといった欠点がある。Conventionally, there have been methods for detecting whether a developer collection box of a cleaning device is full, such as by optical use or by weight detection. However, 1. In the case of the former optical method, malfunctions may occur due to variations in the accumulated state of the collected developer and dirt on the light emitting part and light receiving part, and the latter method, which uses weight detection, can be adjusted due to the light weight of the developer. It has the disadvantages of being difficult to operate and prone to malfunctions.

。On the other hand, the rotation of the photoreceptor drum J, which rotates once per copying operation, is transmitted to the input shaft 13 of the switch operating mechanism IO, and the photoreceptor drum 1 is rotated a predetermined number of times, that is, the developer collection box 7 is rotated to remove the collected developer a. ' When it is full, the output shaft 15 rotates approximately once after rotating a predetermined number of times. Then, the eccentric protrusion 9a of the eccentric cam 9 as an actuator attached to this output m15 via the one-way rotation clutch 16 pushes the operating lever IJh of the detection switch 11 to operate the detection switch 1, and the cleaning device 2 Display section 1 indicates that it is time to clean the permanent agent collection box 7.
2 is lit and the subsequent copying operation is stopped.

回転させられ検知スイッチ１１が復帰した状態となる。When the display section 12 lights up, the operator pulls out the developer collection box 7 and cleans it. At this time, the eccentric cam 9 is forcibly rotated to the reset position by the reset member 20 mounted on the lower surface of the developer recovery box 7, and the detection switch 11 is returned to its original state.
そして、現像剤回収ボックス７を清掃して装着すること
により再び複写可能状態とすることになる。Then, by cleaning and installing the developer recovery box 7, it becomes possible to make copies again.

部に連動させるようにしてもよいことは勿論でおる。Further, although the switch actuation mechanism 10 is configured to decelerate the rotation of the photoreceptor drum and transmit it to the actuator, it may be linked not only to the photoreceptor drum but also to other rotating parts that rotate with the copying operation. Of course.

せることができればどのようなものでろってもよい。In addition, although a gear box containing a worm, a worm gear, and a group of gears is used as the deceleration mechanism 14 of the switch actuation mechanism 10, the structure is not limited to this, and for example, a configuration in which a plurality of Geneva mechanisms are combined may be used. In short, any type of actuator may be used as long as it can rotate the actuator by a predetermined amount to operate the detection switch when the copying operation is performed a number of times corresponding to the maintenance timing of the detected object.
その他、本発明は本発明の要旨を変えない範囲で種々変
形実施可能なことは勿論である。In addition, it goes without saying that the present invention can be modified in various ways without departing from the gist of the invention.

有用であるといった効果を秦する。As explained above, according to the present invention, when the copying operation has been performed a number of times corresponding to the maintenance time of the detected object, the detection switch is mechanically operated to detect the maintenance time. It can be detected that the accumulated state of the collected developer is uneven, especially when the developer is collected in a cleaning device that accommodates the recovered developer that is light in weight. This has the effect of being useful for detecting when the box is full.
