Controller of copying machine

Abstract

Abstract PURPOSE:To carry out copying on various kinds of application paper uniformly, by controlling outputs of transfer, separation, and fixing means in accordance with thicknesses of the sheets to be copied on. CONSTITUTION:Driving force is transmitted to a resist roller 1, and a roller 3 is raised upward by a length corresponding to the thickness of a sheet P. This lift length is detected with a minute displacement detector 7, and a voltage corresponding to the thickness is fed to a control circuit through an amplifier 10. The circuit 11 controls each current and voltage to be fed to a transfer charger, a separation charger, and a fixing device, and allows them to carry out operations corresponding to the paper thickness.
