Claims

[Claims for Utility Model Registration] Optical fiber cables 35, 3 that enter light from light sources 46, 53 from the proximal end and transmit it in the longitudinal direction
6, 54; and radiation surfaces 32, 33 provided at the distal ends of the optical fiber cables 35, 36, 54 and emitting light to the object 13 to be exposed. In order to change the light emission area from the light sources 46, 53, shielding means 48, 55 are provided in the middle of the optical path between the light sources 46, 53 and the emission surfaces 32, 33, and are movable back and forth in a direction intersecting the optical path. An exposure device characterized by:
