Abstract: PURPOSE:To perform sequence control and process control according to the kind of a sheet material which is used actually by detecting the transmissivity of a loaded sheet material and controlling the condition of an image forming process on the basis of the detection signal. CONSTITUTION:When the insertion of the sheet material S is detected with a lever 7, a photosensor 5 receives light from a light emitting part 6 to discriminate whether the sheet material is a film or a paper. When the output of the photodetecting element 5 is inputted to a CPU through an I/O port, an LED1 or LED2 turns on according to the kind of the sheet material to confirm the kind of the sheet. An output port 119 or 120, on the other hand, is turned on and a motor speed is increased or reduced. When an output port 121 is held at L and 122 is held at H, the current value of a high voltage unit HCU1 increases. Thus, the sequence control and process control are performed according to the kind of the sheet.

Abstract: PURPOSE:To make the titled switch easily usable, by mounting a switch lever revolving by the setting provided to a dial rotating at a constant cycle, a switch contact opened and closed by said lever and a manual operation piece freely movable in cooperation with said lever and also used in displaying a contact state. CONSTITUTION:Because a spring member 53 is planned so that the force thereof is weaker than that of a contact spring 59, when a contact mechanism part 60 is turned OFF, a switch lever 55 moves to an A-direction and, therefore, a manual operation piece 50 moves to a B-direction while a knob 51 comes to an OFF-side 52a in a guide slot 52 to shown an OFF-state. In an ON-state, because the lever 55 moves to the direction opposite to the A-direction, the operation piece 50 moves to the direction opposite to the B-direction and the knob 51 comes to an ON-side 52b to show an ON-state. By this method, the ON/OFF states of switch contacts 57, 58 can be visually confirmed.
