〔産業上の利用分野〕
本発明は画像形成装置に用いられるトナーを搬送する際
に、それ以上の搬送が不可能な状態になったことを検知
するトナー検知装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a toner detection device used in an image forming apparatus that detects when toner cannot be further transported when being transported. It is something.
静電複写機等の画像形成装置において、現像・転写され
た後感光体上に未転写像として残留したトナーは、ブレ
ード等による清掃装置にてかき落し、このかき落された
トナーを搬送手段により搬送して回収容器に回収する。In an image forming apparatus such as an electrostatic copying machine, toner remaining as an untransferred image on a photoreceptor after development and transfer is scraped off by a cleaning device such as a blade, and the scraped toner is removed by a conveying means. Transport and collect in a collection container.
通常、このようにして回収されたトナーは再度現像部に
供給されることなく容器が満杯になった時点で容器ごと
機外に取り出し廃棄され、機内には新しい容器が装着さ
れる。Normally, the toner thus collected is not supplied to the developing section again, but when the container is full, the entire container is taken out of the machine and discarded, and a new container is installed inside the machine.
しかし、容器が満杯になっているにもかかわらす装Mを
作動させたり、回収容器の装着が不完全あるいは装着を
忘れた場合、以下に示す状態が生ずると行った欠点があ
った。However, if the device M is activated even though the container is full, or if the collection container is not properly installed or is forgotten, the following conditions occur.
■ トナー搬送のためのスクリュー装置が清掃袋により
飛び出して感光体表面を傷付ける。■ The screw device for conveying toner is thrown out by the cleaning bag and damages the surface of the photoreceptor.
■ トナー飛散が生じ機内を汚す。■ Toner scatters and makes the inside of the machine dirty.
■ トナーが搬送装面部に固着し再使用不能となる。■ Toner sticks to the conveyor surface and cannot be reused.
■ トナー搬送装置の駆動部に過大な負荷がかかり破損
する。■ Excessive load is applied to the drive section of the toner transport device, resulting in damage.
このため従来では該回収トナーを検知する手段として、
光センサー等が多く用いられているが、この光センサー
を用いた検知手段ではトナー回収容器の光透過部がトナ
ー等で汚れた場合誤検知が生じ確実な回収トナーの満杯
検知ができないと言った欠点があった。For this reason, conventionally, as a means for detecting the collected toner,
Optical sensors are often used, but if the light-transmitting part of the toner collection container becomes dirty with toner, the detection means using this optical sensor may cause false detection, making it impossible to reliably detect that the collected toner is full. There were drawbacks.
(発明の目的〕
本発明は上述した従来技術の欠点を解消し、確実な検知
動作を行なえるトナー検知装置を提供することを目的と
する。(Objects of the Invention) It is an object of the present invention to provide a toner detection device that eliminates the above-described drawbacks of the prior art and can perform reliable detection operations.

れている。(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention.
1 shows a transport case 2 extending between a cleaning device (not shown) and the mounting position of the toner collection container 8, and a transport case 2 for transporting untransferred toner on the photoreceptor scraped off by the cleaning device from the cleaning device. Untransferred toner (hereinafter referred to as waste toner) on the photoreceptor that has been carried out by the screw 3 and conveyance 1 creu 3
A shutter member 4.9 is provided to slide in the insertion/removal direction of the toner collection container 8 to open and close the opening 2a for carrying out the toner collection container 8. A slide seat 5 is provided on the inner side of the end of the transport case 2 so that it can move eight times, a sensor (for example, a micro switch, a pressure sensor, etc.) 6 that outputs a signal by the B shift of the slide seat 5, and a shutter member 4 is connected to a toner collection container. It is composed of a spring 7 that slides in the insertion/removal direction of 8.

送を停止する。When the toner collection container 8 is full, the opening 2 of the transport case 2
The waste toner 9, which can no longer be carried out from point a, exerts a force in the direction A (toner conveyance direction), which is not shown in FIG. Due to the force of the toner, which does not reach the same level as above, the slide seat 5 and the detection lever 6a of the sensor 6 move, and the detection part 6 of the sensor 6 moves.
b is pressed, the sensor 6 issues a detection signal and stops toner conveyance.
