Exposure apparatus for photoengraving stamps

Abstract

An exposure apparatus for photoengraving stamps includes a light-proof cabinet having a flash light therein and a drawer adapted to be drawn out therefrom. A clamp is carried on the drawer for holding the stamp. The clamp includes a base fixed to the drawer and formed with a pair of parallel rails, a pair of opposed holders movable on the base along the parallel rails, and means for moving the holders along the parallel rails in opposite directions synchronously. Each of the holders is also provided with a lifter for lifting up the middle plank between the bars and a handle for operating the lifter. Therefore the stamp may be held between the planks just under the flash light when the holders are moved closer together and the middle planks are lifted by turning the handles.
