Title: Electrophotographic device
Inventor: HIRAI HIDEJI
IPC: G03G15/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent a toner image on a photoreceptor from being transferred on a transferring/transporting belt itself, in the image forming system transferring the toner image on the photoreceptor to a recording medium being statically attracted on the transfer-transporting belt. SOLUTION: The image forming operation is started, on making the detection of recording medium 1 as a trigger by a resist sensor 20 arranged in the medium transporting path 4 on the upstream side of the transfer position TP of the toner image. After the recording medium is detected by the resist sensor 20, even if the transporting defect occurs on the upstream side of the detecting position PDP on the medium transporting path 4, the image forming operation is continued by forcibly transporting the recording medium 1 detected by the resist sensor 20. Therefore, the toner image is prevented from being transferred on the transferring/transporting belt 7, and the recording medium 1 itself is also discharged without staying on the transferring/transporting belt 7 part.

Title: Driver output circuit
Inventor: SHIMIZU NOBUO
IPC: H03K19/0175
Filed: 1990-01-31
Abstract: PURPOSE:To shape an output waveform by providing a synchronous pulse generating section and a periodic feedback section and feeding back the output signal of a final stage of a driver output section to the input terminal of an inverter of a final stage. CONSTITUTION:The waveform of an input signal S1 is calculated by the logic circuit of the synchronous pulse generating section 1 and a pulse whose pulse width is T is outputted as a pulse gate signal SP at a point of time t1 when the input level is changed from H to L or changed from L to H. Then the signal SP turns on the transmission gate TG of a periodic feedback circuit 2 to feed back the output signal SOA of a final stage of a driver output section 3 to the input terminal of an inverter 3 at the final stage. That is, while the signal SOA overshoots, an H signal is fed back and while undershooting, an L signal is fed back to obtain the signal SOA with a waveform having a small pulse noise. Thus, the output waveform is shaped and malfunction is prevented.
