Photosensitive material holder for an upright printing machine

In an apparatus of the type for exposing a photosensitive material comprising a holder for holding photosensitive material in an operative position for exposure and means to facilitate loading and unloading photosensitive material the improvement comprising;

• a substantially flat holder having transport guide means located near its top edge and its bottom edge, said holder being adapted to be transported between a first position for exposure of photosensitive material mounted thereon and a second position for loading and unloading of photosensitive material,
• a support structure having a lower guide supporting means which extends laterally between the first position and the second position and an upper guide supporting means spaced from the lower guide supporting means which extends from the first position at an angle to the lower guide supporting means rearwardly of the lower guide supporting means to the second position,
• the holder being moveably mounted between the first and second positions by the bottom edge guide means being transportable along the lower guide supporting means and the top edge guide means being transportable along the upper guide supporting means,
• whereby upon moving the holder from the first position to the second position, the bottom edge is transposed laterally while the top edge is transported simultaneously laterally and rearwardly to rotate the top edge relative to the bottom edge causing the material holder to be rearwardly inclined when in the second position.
