ABSTRACT:
A camera comprising a film winder manually rotatable in a film winding direction about an axis and having a continuous alternating series of teeth and spaces concentric about the axis, and an anti-backup device having a tooth that can be received in any one of the spaces to bottom out in the space in order to prevent reverse rotation of the film winder in a film unwinding direction, is characterized in that the film winder is constructed to be tilted from being perpendicular to the axis in order to only partially retract any one of the spaces that has received the tooth from the tooth, when one manually rotates the film winder in the film winding direction, whereby as long as the film winder is tilted the tooth cannot bottom out in any one of the spaces that has received the tooth. This results in a film winder and anti-backup device that are quietly operating.
