Title: Cleaning mechanism for copying machine
Inventor: AIKAWA MISAO
IPC: G03G21/00
Filed: 1990-07-18
Abstract: PURPOSE:To effectively prevent toner from adhering to a photosensitive drum form a cleaning brush by bringing the fur of a cleaning brush into contact with the outer periphery of a sweeping body so that the contact position may be consecutively changed and sweeping the toner adhering to the fur. CONSTITUTION:A part of toner adheres to the fur 5 of the cleaning brush 2 from the photosensitive drum 1 and is swept by beating the fur 5 against a rotary shaft 8. Since the rotary shaft 8 receives driving force from the brush 2 and consecutively rotates around a shaft center line in the middle of copying actions, the fur 5 of the brush 2 is brought into contact with the outer periphery of the shaft 8 so that contact position may be consecutively changed. //As a result, the temperatures of the shaft 8, the fur 5 of the brush 2 and the toner adhering to the brush 5 hardly rise even when the copying actions are consecutively performed for a long time. Thus, the toner is effectively prevented from being fused and stuck to the photosensitive drum 1 from the brush 2 and a maintenance and inspecting operation for a copying machine is facilitated.

Abstract: PURPOSE:To prevent mulfunctioning of an oxygen starvation detecting circuit due to combustion instability occurring when the temperature of the air for combustion is decreased, by a method wherein, when a room temperature is extremely decreased, the output of the oxygen starvation detecting circuit is locked. CONSTITUTION:A device is provided with an AND circuit 12. The output of an oxygen starvation detecting circuit 10 set to a level higher than that of a detecting circuit 11 for failure in ignition operated when a combustion condition is extremely worsened, and the outputs of timer circuits 13-17, which are operated for a given time after the starting of combustion, are caused to produce an input by said AND circuit. Further, an AND circuit 54 is provided for connecting the output of said AND circuit 12 to the input of a reset circuit formed with an OR circuit 37. Further, the latter AND circuit causes the output of the timer circuit 17 and the output of a detector 53, operated when a room temperature is extremely decreased, to produce an input, and inputs the outputs to the AND circuit 12. With this, under a room temperature condition down to the minus input level of the detector 53, the output of the oxygen starvation detecting circuit 10 is locked by the timer circuit 17 which is operated for a given time of the primary stage of combustion. However, when a room temperature is increased and exceeds a given level, the output is released from the locking condition, and the oxygen starvation detecting circuit is operated at a normal set level.
