Abstract

PURPOSE: To automatically erase the unnecessary image on a sheet by a simple operation by comprising an erasing roller for erasing an image and an operation key for indication which drives the erasing roller to erase a single page or continuous pages. CONSTITUTION: When the erasing of the image is needed after the electronic blackboard has been used, an erasing key on an operation part 16 is pressed, whereby the erasing solenoid 40 is switched on, an erasing motor as a driving source of an erasing roller 41 is rotated, and an outer peripheral part of the erasing roller 41 is closely brought into contact with a take-up guide roller 42 through a sheet 1. The sheet 1 is fed by the rotation of an SM 24, an image on the surface is erased by the erasing roller 41, the sheet is stopped when a sensor 8 detects a page mark of the sheet, and the erasing motor and the erasing solenoid are switched off. Then the erasing roller 41 is drawn by a spring 43 to be separated from the sheet. When a repeat key on the operation part is pressed, the erasing operation is continued by the time when the last page of the page mark of the sheet is detected.
