<p>A control strip holder having a light interrupting door opened and closed by the instruction of an external open-and-close instruction means is installed on the exposure table of an automatic printing and developing machine, which is provided with the open-and-close instruction means. The control strip is automatically drawn out from the holder, held onto the exposure table by air-suction and transferred to the developing unit. The control strip is drawn out by the holding force of the exposure table. As a structure for concentrating the holding force on the driving of the control strip, a mask plate is provided on the control strip holder to cover almost all the holding zone of the exposure table. The leading end of the control strip remaining outside the control strip holder is held on the exposure table by a force which is stronger than that exerted on normal paper. Thus, the control strip is transferred to the developing unit through the outlet by the paper conveying belt of the exposure table.</p> |
