Abstract
A copying area display device for a copier and allowing the operator to easily position a document on a glass platen. The device displays an effective image reading area which is easy to see. When a cover plate is opened, a carriage included in a scanner is moved to one of four sides of the effective image reading area. Scales, lamps or movable marks are arranged around the glass platen and on the carriage. Alternatively, a liquid crystal display may be built in or superposed on the glass platen to display the contour of an effective image reading area. When the cover plate is closed, the scanner is returned to a home position thereof.
