Title: Position correcting device for original
Inventor: KAMIBAYASHI HIDEYUKI
IPC: G03G21/00
Filed: 1988-04-12
Abstract: PURPOSE:To automatically correct the position of an original and to prevent miscopying when the dislocation of the original occurs by switching from scanning movement to returning movement at high speed. CONSTITUTION:A detecting means 18 detects the dislocation of the original placed on an original platen 16. Detection by the detecting means 18 is performed by, for instance, optically reading an original image with the scanning movement of the original platen 16 and comparing the read position of an image with the initial position of the image or with the previous position of the image. When the dislocation of the image is detected, the original platen 16 is switched from the scanning movement to the returning movement at high speed, thereby rapidly inverting the moving direction. Thus, position correction can be automatically achieved and miscopying can be prevented.
