ABSTRACT:
A camera comprising a backframe opening for exposing successive sections of a filmstrip, a rigid deflector pivotally supported at one end of the backframe opening to permit a leading edge of the filmstrip which is advanced against the deflector to pivot the deflector away from the backframe opening to allow the leading edge to be advanced over the deflector rather than become trapped in the backframe opening, and a return spring which is weaker than the force of the leading edge against the deflector for returning the deflector to an original position, is characterized in that the deflector and the return spring are an integrally formed single piece.
