ABSTRACT:
A film pressing device for use in an electrophotographic apparatus and adapted for pressing an electrophotographic film onto a processing head in the apparatus. The device includes a pressing plate for pressing the electrophotographic film onto the processing head and having a through-hole formed in the pressing plate for allowing a projecting light to pass therethrough. A light-shielding plate is provided on the pressing plate at one side of the through-hole so as to prevent any portion of the projecting light failing to pass through the through-hole from impinging upon portions of the electrophotographic film which are to be kept away from the projecting light. Thus, any portion of the light scattered from the light path between the projecting light source and the through-hole is prevented from reaching such portions of the electrophotographic film.
