PURPOSE:To eliminate the need of repeating useless original size detection and simultaneously, to show an advantage that the original size detection is carried out by resetting an original size detection state when an original cover is opened, and the original is removed from an original platen. CONSTITUTION:This image forming device is composed of an original scale 32, the original platen 34, a first carriage 38a, first and second sensors 60a and 60b, a mode selecting key 31d, etc. Even if the original cover is opened after the first copying is carried out, the original size detection is not released when the original is placed on the original platen 34. Thus, when the same original is copied, again, the copying is quickly carried out. |
