IPC: G03G21/06
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To easily and surely perform a discharging operation by starting the discharging operation based on a detection signal. SOLUTION: An electrostatic charging AC bias is switched to OFF state after continuing an ON state (discharging) at least by the amount of one rotation of a drum after an electrostatic charging DC off timing. By discharging by the amount of one rotation of the drum, a history such as a memory and toner sticking accompanying an image forming operation are eliminated from the photoreceptor drum 2. And also, a vibration voltage is not impressed longer than required, so that the deterioration of the surface of the photoreceptor drum 2 is suppressed. By such the operation, a transfer material is guided to a paper ejecting part by a paper ejecting roller 15, or 16 by way of a fixing device. When the leading end of the transfer material reaches a paper ejection sensor 11 after passing through the fixing device 8, a paper election sensor signal is switched from ON to OFF.  And, when the transfer material passes through the paper ejection sensor 11, the signal is switched from OFF to ON. Just before the stopping of the device, discharging is performed by the amount of one rotation of the drum, and after the photoreceptor memory, etc., are removed, the device comes to a standstill.

IPC: H04B1/06
Filed: 1987-09-24
Abstract: PURPOSE:To attain cost reduction and to realize small size by providing an action of an RDS interruption function switching means to an ARI interrupt function switching means. CONSTITUTION:When a detection output A obtained by an FM broadcast recep tion means 2 has neither a TA signal nor a DK signal, no detection signal DK is outputted from a DK signal detection means 4 and the ARI interrupt function changeover means 6 outputs an external audio signal B from a tape reproducer 11 as an audio signal C. When the TA signal is received and the detection signal TA is outputted, a freerun frequency F of a free-run frequency output means 13 is given to the DK signal input means 12 via an interrupt operation changeover means 20 to output the detection signal DK. Thus, the changeover means 6 goes to the interrupt state and the detection signal A becomes the audio signal C. Similarly, the DK signal is detected as the detection signal A, then the detection signal A becomes the audio signal C.
