Abstract

PURPOSE: To achieve the improvement in the cooling effect of original setting glass by providing an openable screen along the lower side of the glass on which originals are to be placed and sending cooling wind between the screen and the glass.
CONSTITUTION: A screen 5 is provided along the bottom side of original setting glass 1 and this screen 5 is connected at one end to the holder of a lamp 4 and is provided at the other end with a weight 6. It is so arranged that it is supported parallel to the original setting glass 1 by a screen roller 7. Further, the cooling wind produced by a cooling fan 2 is guided to a guide plate 8 so that it is flowed between the screen 5 and the glass 1. Thereby, the glass 1 may be effectively cooled. In addition, the screen 5 does not hinder the exposure because it is pulled by the weight 6 while mirrors 3, 3a and lamp 4 are moving in the arrow direction for the purpose of exposure until it comes back the home position upon ending the exposure.
