Abstract

PURPOSE:To raise operability at the time of manufacturing and assembling a cleaning device and at the time of its check by connecting a lever for applying a force by a pin, etc. in plural parts, and also to prevent a cleaning member from being rolled in at the time of an abnormal load by engaging the pin to a side plate of the device in an idle-fitted state. CONSTITUTION:A pressure lever 15 and the second supporting member 12 are connected by a connecting pin 16 and a rotating shaft 13 in two parts, therefore, they become rotatable as one body around it within a range of a center angle D centering around the rotating shaft 13 defined by a caliber C of an inserting hole 14a. Accordingly, a setting angle of the pressure lever 15 for determining the magnitude of elastic force of a pressure spring 17, to the second supporting member 12 is determined by a shape of the pressure lever 15, and it becomes unnecessary to adjust it at every time of disassembly and assembly. The connecting pin 16 is engaged so as to be rotatable and movable by the angle D in the circumference of the rotating shaft 13 by the inserting hole 14a of the side plate 14 of the connecting pin 16, therefore, such an inconvenience as a blade 8 is rolled into a rotation of a photosensitive drum 7 is prevented.

で連結される構成となる。Insertion holes 10a and 15a having the same diameter are formed in one end of the pressure lever 15 and in the distal end surface of the intermediate shaft 10 facing the side plate 14 so that their centers coincide with each other. . Similarly, the diameter of the side plate 14 located in the middle of these holes is set so that the center of the side plate 14 is aligned with the center.
A larger insertion hole 14a is bored. As shown in FIG. 4, the diameter C of this insertion hole 14a is ensured to be about 2 to 3 times larger than the diameter of other insertion holes, and the opening position is such that the blade 8 is on the photoreceptor. It is set so as to come into contact with a desired position on the circumferential surface of the drum 7. One connecting pin 16 is provided so as to communicate with the two insertion holes 10a, 15a and the insertion hole 14a, and is connected to one end of the second support member 12 which is externally inserted into the intermediate shaft 10. Pressure lever 15-1
The end is a connecting pin 16 that is loosely fitted into the insertion hole 14a of the side plate 14.
The configuration is such that they are connected.

体１８に固着されている。Further, a locking hole 15b is formed at the other end of the pressure lever 15, and one end of a pressure spring 17 is locked in this hole.
The other end of this pressure spring is secured to a suitable base 18 of the unit device.

Then, this moment M is the second moment. This is transmitted to the blade 8 via the first support member 12°9, and becomes a contact force F2 when the blade 8 contacts the surface of the photoreceptor drum 7 in the direction of the arrow. Further, on the left side of the locking hole 15b in the drawing, an appropriate number of other locking holes are arranged in parallel. In this embodiment, two locking holes 15c and 15d are bored at positions I12°13 apart from the center of the rotating shaft 13, and therefore lock one end of the pressure spring 17. Locking hole 15b
, 15c, and 15d, the magnitude of the moment M is changed in three stages,
In accordance with this, the magnitude of the contact force F2 of the blade 8 can also be changed in three stages.

回転可能となる。By configuring the support mechanism for the blade 8 as described above, the pressure lever 15 and the second support member 12 are connected to the connecting bin 16.
Since the rotation shaft 13 is connected at two places by the rotation shaft 13, the rotation shaft 1 defined by the diameter C of the insertion hole 14a as shown in FIG.
It becomes possible to integrally rotate around the center angle within the range of the central angle around 3.

簡単となる。Therefore, as mentioned above, the pressing spring 17 of the pressing means
The mounting angle of the pressure lever 15 relative to the second support member 12, which determines the magnitude of the elastic force of the pressure lever 15, is determined by the shape of the pressure lever 1\-15, which eliminates the need for adjustment each time it is disassembled and reassembled as in the prior art. The assembly work for this part becomes much easier and simpler.

By configuring the blade 4a to be engaged so as to be rotationally movable by an angle around the rotating shaft 13, the inconvenience of the blade 8 being caught in the rotation of the photoreceptor drum 7 when an abnormal load is applied to the blade 8 can be prevented. be done.

好なりリーニング効果が安定して発揮される。In the above-mentioned embodiment having such a configuration, when the residual toner on the circumferential surface of the photosensitive drum 7 is conveyed to the contact position of the blade 8 as it rotates, the blade 8 resists when scraping off this toner. As a result, a pressing force F3 along the rotational direction of the photosensitive drum 7 is applied. As a result, the above-mentioned 1. The blade 8 is also moved in substantially the same direction as the floating fulcrum Q defined by the intermediate shaft 10 connecting the second support member 9.12, but due to the elastic force of the coil spring 11 and the pressure spring 17,
The tip of the blade 8 is kept in contact with the surface of the photoreceptor drum 7 with appropriate pressure. That is, the floating fulcrum Q is moved and the angle B formed by both support members 9.12 becomes smaller.
Correspondingly, the elastic force F4 of the coil spring 11 also increases to resist the pressing force F3, and the pressure spring 17 brings the moved blade 8 into contact with the circumferential surface of the photoreceptor drum 7 with an appropriate pressure. . As described above, the blade 8 flexibly responds to the applied load by the pressing means made of two elastic members and is always pressed against the surface of the photoreceptor drum 7 with an appropriate pressure. It can be removed easily and the leaning effect is stably exhibited.
