Abstract

PURPOSE:To enable good quality copying to be performed by so constituting the apparatus that the position of an original platen or exposure lamp to be accurately detected and controlled. CONSTITUTION:Either of a lead switch 8 or a permanent magnet 9 is mounted to an original platen, and the remaining one is fixed and is used. In the central part of the reed switch 8, the lead switches makes OFF operation, and ON operation exists at both ends away several mm. from the central part of the reed switch. From this, the reed switch makes ON operation if the position of a permanent magnet 9 is selected at the point A which is Y=Q, Z=P. Next, if said magnet 9 is moved by maintaining Z=P, Y=Q in the section Z=P, the switch 8 goes ON over >=40mm.. From this, the switch 8 operates always in the same position, and the ON operation distance or ON operation time of the switch 8 of the original platen is prolonged more than the length in the moving direction of the magnet 9. Hence, the copying of good quality is accomplished.
