PURPOSE:To prevent the occurrence of a down time and to prevent unnecessary copying by selecting another transfer form feeding device to continue copying with a variable power ratio suitable for the transfer form size of this transfer form feeding device if transfer forms in one transfer form feeding device run out. CONSTITUTION:Transfer forms to which original images are transferred are fed out from form supply trays 2003 and 2004 arranged in a copying machine 100 or form supply trays 2001 and 2002 in a form feeding bank 400 provided independently of the copying machine 100. An optical system which exposes a photosensitivity body 116 to the reflected light from a lamp 109 is not only capable of unmagnification copying but also provided with a variable power copying function. The variable power ratio is changed by changing positions of mirrors 110, 111, 112, etc., the position of a lens 113, and the mirror moving speed. The variable power ratio is determined by the command from a controller which controls the whole of the copying device. |
