Abstract

PURPOSE:To discriminate the quality of a switch easily by simple operation such as mode switching operation during the fabrication of a machine device, and its repair, inspection, etc., by checking the switch by the mode switching of a controller. CONSTITUTION:An original platen 11 moves to right to project an original image on a photosensitive drum 2 through an optical system which consists of a lamp 12, mirrors 13a and 13b, a lens 14, etc. According to the movement of the original platen 11, a magnetic 11a provided under it operates a constant position switch SW1 made of a reed switch, a timing switch SW2, and a return switch SW3. A pulse signal generator 22 generates a pulse train by utilizing the rotation of a disk 21. Signals from said switches SW1, SW2, and SW3, a pulse signal generator 22, etc., are discriminated by a controller 41 provided with, e.g., a microcomputer.
