JPS54141130A - Electrophotographic copier - Google Patents

Abstract

PURPOSE:To obtain always stable picture images by a simple operation and facilitate maintenance, by operating the control mechanism wth the detection signal of sensitive paper detector, and successively performing each process of copying by operating plural switch means sequentially. CONSTITUTION:When a print button is depressed with the original placed on an original platen 1, an automatic feed roller 6 rotates as specified to send out the top sheet of sensitive paper 5-1 in a container 5. When a sensitive paper detector SW8 detects the end of the sensitive paper, an optical box 12 s shifted to the right. The sensitive paper is further sent by a first paper feed roller 39 and is charged by a charger 10 to be forwarded into a transfer section 11. When the rear end of the sensitive papper is detected by SW8, the control mechanism begins to act, of which first signal stops a transfer belt 11-1. The second signal therof completes the preparation for development, the third signal causes the optical box 12 to light up an exposure lamp 12-3, and the fourth signal shifts the optical box 12 to the left, thereby performing exposure. After the completion of exposure, the transfer belt 11-1 moves to send the sensitive paper to a development section 17, thereby discharging into a tray 24 by way of squeeze roller 18 and drying section 22.
