PURPOSE:To express display contents indicting the operation state or the like of a copying machine more understandably and to enable an operator of a copying machine to recognize many information in detail and concretely by displaying plural films optically recording information such as an alarm and an indication to the operator as a selective projection image. CONSTITUTION:A braking part 24 is driven through a driving circuit 21 on the basis of an output signal from a film selecting part 20 and an electromagnetic solenoid 7 is driven to project a pin 8. When the pin 8 is projected, the pin 8 is engaged with a claw 9 to stop a disc 5 at its position and an output signal is sent from the driving part 21 to an illuminating part 25 to light up a hologen lamp 1. The light is irradiated upon a selected display film 6 on the disc 5 through a heat-resistant glass 2, a condensor lens 3 and a light shielding plate 4 and the transmitted light through a display film 6 is projected upon a transmission type screen 14 through a projection lens 13. Thus, the transmitted light through the display film 6 is formed on the screen 14 as an analog image such as pictures or characters or color display. |
