Abstract: An improved motion picture film projector (100) comprises a Geneva Mechanism (120), which intermittently drives a film (114). A light source (116) projects light through the film (114) and a shutter (106) periodically interrupts the light source (116). The shutter (106) has a blade with a shaped edge, which matches the frame shape on the film (114) thus, increasing the amount of light that is transmitted through the film (114). A second edge of the blade also matches the frame shape on the film (114) further increasing the amount of light transmitted through the film (114).

Abstract: A method and mechanism for adjusting the timing of a camera in the reverse mode while allowing for separate adjustment of the timing in the forward mode. In a preferred embodiment, an external switch is provided which when actuated switches the camera between the timing setting for the forward direction and the timing setting for the reverse direction. A helical driven gear which engages a drive gear driven by the motor is axially translatable between a first position corresponding to the forward direction and a second position corresponding to the reverse direction. Since it is a helical gear, the amount of axial translation adjusts the relative angular position of the shutter with respect to the frame advance mechanism.
