ABSTRACT:
An instant type camera is provided with an imbibition chamber having (1) a window in one wall thereof through which an exposed and developed film unit may be viewed and (2) an egress through which an exposed and developed film unit may be manually advanced to the exterior of the camera by actuation of a film pusher assembly. An opaque shade is mounted for movement between an operative position, in which it prevents entry of light into the imbibition chamber during a time period when an image in the film unit is being developed, and an inoperative position in which the window is uncovered. The shade includes means which prohibits operation of the film pusher assembly when the shade is in its operative light blocking position.
