ABSTRACT:
A film gate formed as one integral unit by molding a black synthetic resin material includes a film gate portion, a recess for receiving a film driving member for reciprocal movement therein, film guide walls, positioning means and protective walls to protect resilient side pressure members from damage from careless loading of a film magazine. The positioning means may be used as reference position to secure the gate unit to a fixed frame of a motion picture apparatus. The side pressure members are formed as extensions of a holding member that also applies resilient force to the film driving member near the root of its film-advancing pawl.
