Abstract
A film initial-advance apparatus for a camera which enables the initial advance of a film by a reciprocating feeding claw, and in which a gear train for film feeding and driving members are disposed on the same side of a spool. A feeding member is disposed on a reciprocating driving member which reciprocates in the direction of film feeding. A gear train for feeding the film is connected to the driving gear on the side of the reciprocating driving member, and the rotational driving force of the driving gear is transduced to the reciprocating movement for reciprocating the reciprocating driving member. A cam groove is formed in the reciprocating driving member, and the feeding claw is advanced toward and withdrawn from a perforation of the film. The speed of the reciprocating movement of the reciprocating driving member is set to be lower than the film feeding speed.
