Abstract

PURPOSE:To recover collected toner easily by providing a lid body to the rear surface release part of a box-type container containing a cleaning blade so that the lid body freely slants, and taking a toner collection box out of the box-type container by releasing the lid body. CONSTITUTION:The box-type container 4 which contains the cleaning blade 5 fixed to an oscillatory shaft 6 is covered with the rear surface lid 1 which slants around a fulcrum shaft 10 as a fulcrum. When the toner collection box 16 is taken out of the box-type container 4, the rear surface lid 11 is opened by operating a manual lever to draw the collection box 16 out. Therefore, it is unnecessary to detach the whole cleaning device, so that collected toner is recovered easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for cleaning the circumferential surface of a photosensitive drum of, for example, an electrophotographic copying machine, and more particularly to a blade cleaning device having a cleaning blade that is pressed against the surface of a rotating body.

As is well known, when maintaining and managing a blade cleaning device, it is necessary to remove the collected toner scraped by the cleaning blade from the main body of the cleaning device. The main body of the cleaning device, including the cleaning blade, is removed from the main body of the copying machine, and the collected toner in the main body of the cleaning device is removed.

An object of the present invention is to obtain a structure in which collected toner can be easily collected without removing the entire cleaning device from the machine body. The present invention proposes a structure in which a lid pivotally supported on a container is tiltably attached, and a collection box for collecting foreign matter scraped off by the cleaning blade is mounted on the lid.

Hereinafter, details of embodiments of the present invention will be explained with reference to embodiments shown in the drawings.

The illustrated embodiment is a cleaning device A attached to a photoconductor drum 1, and this cleaning device has a front opening 2 and a rear opening 3 facing the circumferential surface of the photoconductor drum 1. A box-like container 4 is provided, and four sets of containers 4 are provided.
A cleaning blade 5 whose tip end is pressed against the circumferential surface 1a of the photoreceptor drum 1 is positioned in the front open portion 2 of the photoreceptor drum 1. That is, this cleaning blade 5 is attached to a support arm 7 fixed to a swing shaft 6 with a fixing screw 8, and a counterweight 9 is provided at the tip of the support arm 7 to apply a pressing force to the cleaning blade 5. (It is fixed.

On the other hand, the rear facing D bottom portion 3 of the box-like container 4 is tilted 1 with the fulcrum axis lO at the lower part of the box-like container 4 parallel to the photoreceptor drum 1 as a fulcrum.
It is rolled on the rear surface M l '' which can be produced at ω1.This rear surface lid 11
As shown in FIG.
A manual operation lever 12 that can be operated with a fingertip is attached to the upper part of b.

That is, the manual operation lever 12 attached to the rear lid 11 with a shaft 13 is rotated clockwise with a spring 14.
The hook 12a is locked to the bottle 15 planted in the garden.

Further, on the rear lid 11, there is a collection box 6 for collecting the toner taken into the box-shaped container 4. The collection box 16 has a front opening 16a facing a guide plate 18 guided from Mylar paper 17 directly below the cleaning blade 5, and the toner taken into the box-shaped container 4 is 1
8 into the collection box 16.

Since the cleaning device according to the present invention has the structure described above, in order to take out the collection box 16 from the box-shaped container 4, the manual operating lever 12 is operated with a fingertip, and the rear cover 11 is moved as shown in the third figure. You can open it like this. When the rear lid 11 is in the open state, the collection box 16 remains on the rear surface H1x,
Since the front opening 16a is oriented on one side with the front opening 16a facing upward, the collected toner can be collected by simply pinching the upper part of the collection box 16 and lifting it upward. Of course, the cleaning device input pressure collection box 1
6, open the rear ill and open the rear cover l.
It is sufficient to simply place the collection box 16 on top of the container and close the rear lid 11.

In the end, according to the present invention, the collected toner can be collected by simply opening the rear cover without removing the entire cleaning device from the machine body as in the conventional case, allowing for quick maintenance without getting your hands dirty. become.
