Title: Image forming device
Inventor: OGASAWARA MASATO
IPC: G03G21/10
Filed: 1989-02-13
Abstract: PURPOSE:To stabilize image quality and to prolong the life of a photosensitive body by forming a cleaning means in plural stages, changing the behavior of constituent elements of the cleaning means, and eliminating the influence of residual toner on the photosensitive body at the time of exposure. CONSTITUTION:A cleaning member 109 consists of brushes 135a and 135b and the brush 135a can be slid by a pulse motor 150 laterally in the generating line direction of the outer periphery of the photosensitive body 101. Then lumps of toner remaining on the photosensitive body 101 are stirred up by the lateral movement of the brush 135a and smoothed, and attracted to the brush 135b temporarily. The attracted toner is pushed out to behind the brush 135b and stuck dispersedly on the surface of the photosensitive body 101. Therefore, a memory phenomenon due to the residual toner at the time of the exposure can be precluded. Further, the brushes 135a and 135b are formed of soft members to eliminated the flawing of the photosensitive body.

Filed: 1982-03-01
Abstract: PURPOSE:To perform the maintenance in each device without having influence upon operations of other devices, by providing one bus use request signal line connected in common to plural devices having a common bus and assigning priority levels to respective devices. CONSTITUTION:When a bus use request is generated in a bus access circuit BAS, a signal REQi is activated. At this time, if a signal line L is in an inactive state, the signal REQi passes through a gate NAND and sets an FF 1. If the signal line L is in an active state, the gate NAND is closed, and the FF 1 is not set. When the FF 1 is set, the output of the FF 1 activates the signal line L through an inverter INV1, and a signal DATAi is outputted to activate a signal line (i) assigned to a device A out of signal lines constituting a bus B. If the contention is caused by request signals from other devices, a priority level discriminating circuit PRIC makes a signal PRI high-level and outputs a bus activation confirming signal ACKi through an FF 2 after a prescribed time only when the device A among devices corresponding to activated signal lines has the highest priority level.
