Abstract

PURPOSE:To eliminate the danger that the operator receives exposure by providing a safety means of intercepting higher energy beam from the optical path of the information recorder which combines a copying device having an original platen and a laser beam printer. CONSTITUTION:A plunger 30 is connected to the support member 8S of the reflecting mirror 8 of the copying device and when the plunger is energized, the reflecting mirror 8 is moved to the solid line position and closes an opening 28P so that a shield box 28 is tightly closed. A select circuit 33 for the copying machine and laser beam printer is provided to the copying device and is so constituted as to be selectable by the external signal or control panel 35 by way of an interface 34. Hence, the reflecting mirror 8 acts as a sealing member to tightly close the laser exposure part to the shield part 28. The tight closure of the exposure part in this way obviates the danger upon the operator despite the emission of laser beam.
