Title: Fixing device
Inventor: ISHIKAKE SATORU
IPC: G03G15/20
Filed: 1992-04-17
Abstract: PURPOSE:To uniformly execute cleaning by making the magnitude of load by component force for moving the center of a gear which acts on a cleaning roller and an elastic member on the gear side equal to the magnitude of the load by an elastic member on an opposite side to the gear side. CONSTITUTION:The magnitude of the load obtained by adding the pressuring force of a spring 34 on the gear 33 side to the component force F2 is made equal to the magnitude by the pressuring force of a spring 35 on the opposite side. Supposing that the pressuring force on the gear 33 side of the cleaning roller 30 is P, P=P1-F2 holds, and the pressuring force on the opposite side of the roller 30 is still P2, then the magnitude of the pressuring force P1 and P2 of the springs 34 and 35 are set so that P1+(-F2) P2 may hold to obtain P P2. Namely, the pressuring force P1 of the spring 34 is set to be larger than the press force P2 of the spring 35 by F2. By such constitution, the difference of the pressuring force between the gear 33 side of the roller 30 and the opposite side is hardly found.

Filed: 1990-04-13
Abstract: PURPOSE:To enable high-resolution detection over a wide detection range by inputting the output of a field effect transistor(FET) to plural amplifying circuits which differ in amplification gain by the semiconductor sensor, and obtaining plural detection outputs. CONSTITUTION:When the FET 2 is stressed, the drain current ID of the FET 2 varies and this variation is applied to a current-voltage converting circuit 3 to generate a voltage output 3e, which is sent to 1st and 2nd amplifying circuits 4 and 5. The circuit 5 is set in voltage gain lower than the circuit 4. The output 4b of the circuit 4 is supplied by a switch circuit 9 to a selection output terminal 6c in a range wherein the stress applied to the FET 2 is weak. When the stress is large, the output 7a of a comparator 7 which monitors the output level of the circuit 5 goes up to an H level and the circuit 9 is switched to a dotted-line side through a timer circuit 8 to supply the output 5b of the circuit 5 to the terminal 6c. Consequently, a high-resolution detection output is obtained over a wide range from a fine input to a large input.
