ABSTRACT:
In a film cassette, a film stripper is located relative to a film egress passageway to be received between the film leader and the next inward convolution of a film roll to direct the film leader into the passageway responsive to rotation of the film roll in an unwinding direction. According to the invention, the stripper is united with a light blocking device for movement, when the light blocking device is moved to a light blocking position relative to the passageway, to a non-stripping position out of reach of the film roll to prevent receipt of the stripper between the film leader and the next inward convolution and for movement, when the light blocking device is moved to a non-blocking position relative to the passageway, to a stripping position within reach of the film roll to allow receipt of the stripper between the film leader and the next inward convolution.
