Claims

[Scope of utility model registration request]

In order to record information on a card-shaped recording medium and/or to reproduce recorded information using an optical head or a magnetic head, the recording medium is moved relative to the head. In a card drive device that moves, a flywheel is attached to the rotating shaft of a motor, and a rotation transmitting member is provided with a drive section that transmits rotation to the flywheel, a brake section that stops the rotation, and a rotation transmission member that is pressed into contact with the drive section. In this case, there is a pair of friction wheels driven to rotate in opposite directions, a rotatable shaft to which these friction wheels are attached, and a rocking or reciprocating shaft attached to the shaft with this axis as the central axis of rotation. A card drive device comprising a mounting frame into which the recording medium can be mounted.
