Abstract

PURPOSE:To make possible extremely easy and delicate adjustment by providing an adjusting means which adjusts the fixing position of a revolving shaft of a cleaning brush and a means for storing the fixing position of the revolving shaft which stores the fixing position. CONSTITUTION:Screws 10, 10' are thoroughly screwed to fix a plate 9 for storing the fixing position to a supporting plate 5 and to determine the fixing position of the free revolving shaft 12 in the position where the cleaning brush 1 and a photosensitive body are in suitable contact with each other. The screws 6, 7 are then thoroughly screwed to fix the plate 5. Even if the plate 5 is thereafter removed from a front face frame 3 by exchanging the cleaning brush 1, etc. the length of the contact between the brush 1 and the photosensitive body is similar to the length prior to the removal as far as the screws 6, 7 are again inserted into screw holes 5a, 9b(5b) to attach said plate to the frame 3.

る。The upper and lower ends of the support plate 5 are provided with screw holes 5a and 5b through which screws 6.7 pass. A screw 6 passes through the screw hole 5a. This screw 6 is screwed into a nut portion 3a bored in the front frame. The screw hole 5b is an elongated hole having a width that allows the screw 7 to pass through, and is formed by a part of the circumference around the screw hole 5a. Nut portions 5c and 5d are bored on the circumference near both ends of this screw hole 5b. Screws 10.10' are screwed into the nut portions 5c and 5d. The fixed position memory plate 9 is fixed to the support plate 5 by this screw. The fixed position memory plate 9 is for storing the fixed position of the support plate 5 adjusted by the elongated hole 5b.

る。The fixed position memory plate 9 has a screw hole 9b through which the screw 7 passes, and screw holes 9C and 9d through which the screws 10 and 10' pass. The screw hole 9b is a hole of the same size as the screw hole 5a of the support plate 5, and is large enough to allow the screw 7 to pass through it without moving. Both screw holes 9C and 9d are long. When the fixed position memory plate 9 is attached to the support plate 5 by passing the screws 10' and 10' through the screw holes 9c and 9d and then screwing them into the nut parts 5c and 5d, It is bored so as to constitute a part of the circumference around the screw hole 5a. This allows the screw hole 9b to move within the range of the support plate 5o'' long hole 5b.

感光体１４との接触の長さが変化する。In FIG. 3(A), the screws 6.7 are screwed into the NAND parts 3a and 3b of the front frame, but are not completely screwed into them. Similarly, the screws 10 and 10' are connected to the nut portion 5c of the support plate 5.
, 5d, but not completely screwed together. In this state, the support plate 5 swings around the screw 6 within a range where the screw hole 5b moves through the screw 7. This is because the screw hole 5b is formed so as to form part of the circumference around the screw hole 5a. Fixed position memory board 9
are penetrated by the screw 7 and do not move freely, so the screws 10 and 10' screwed into the support plate 5 move within the screw holes 9c and 9d. Along with this swing, the free rotation shaft 12 also swings around the screw 6. Since the cleaning device is fixed in the copying machine, the length of contact between the cleaning brush 1 and the photoreceptor 14 changes due to this swinging.
