ABSTRACT:
In an electric motor drive device for a camera having first and second one-way clutches arranged to transmit a driving force either to a film winding transmission member or to a film rewinding transmission member by a change-over operation on the rotation of a driving motor between normal and reverse rotating directions, a charge cam provided between the first one-way clutch which transmits a driving force of the rotation of the motor in the normal direction to the film winding transmission member and the winding transmission member is arranged to rotate together therewith. The charge of a charge mechanism disposed within the motor drive device resulting from the rotation of the charge cam is arranged to be effected approximately in phase with the charge of a charge mechanism which is disposed within the camera and is arranged to be driven by the winding transmission member.
