ABSTRACT:
A box type contact printer for photographic plate making is disclosed. A lower frame and an upper frame positioned thereon, the latter being made of a transparent material, are pivotally connected to each other at their rear ends so that a photosensitive material and an original picture put thereon may be positioned between the two frames, and a shield box having a front opening for covering the frames includes an exposure light source in its inside top. The front opening is adapted to be covered by a roll-up curtain. At least one lower front corner portion of the side walls of the shield box is diagonally cut off, and the upper frame is provided with a shield plate which is disposed so as to shield the cut-off portion of the cut off side wall when the lower and the upper frames are closed.
