Abstract
A contact printer includes a printing table for mounting of photosensitive material thereon, a framework for supporting a light-transmitting plate, a packing, a conveyor belt for movement of an original in X and Y-directions, and an air-blowing nozzle and drive means for open and close operation of the framework. The framework is held at a position where it is in a slightly opened state during movement of the original, supported by the blown air in order to prevent the photosensitive material from being damaged and to insure accurate positioning of the original.
