Abstract

PURPOSE: To reduce vibrations and enable stable optical scanning to be done by constituting support members for supporting a scanning lighting means and support members supporting a scanning mirror means to separate bodies.
CONSTITUTION: The 1st mirror 4 is mounted to a mirror base 34 and one side of the mirror base 34 is slidably fitted to a guide rail 27 and the other side is supported and guided by a roller 35 on a guide rail 28. The mirror base 34 is so arranged that is makes scanning and returning by being driven by wires 36, 37. On the other hand, on original lighting lamp 3 is supported by the sockets 321, 322 mounted to a lamp base 38 and a reflecting shade 33 is also mounted to the lamp base 38. The lamp base 38 is also guided by guide rails 27, 28 similarly to the mirror base 38 and is driven by wires 40, 41. The wires 40, 41 and wires 36, 37 are connected to the same drive source and are driven at the same speed in the same direction.
