Abstract: An idler mechanism for a magnetic tape device. An idler gear is swingingly displaced between first and second positions to selectively transmit rotation to one of a pair of reels. One end of an arm-like swinging member is coupled in a relatively rotatable manner to a center shaft of an input gear which always meshes with the idler gear and which is rotated forwardly and reversely. A shaft which is disposed on the other end of the swinging member is inserted in a relatively rotatable manner into a bearing hole of the idler gear. A surface of a flange which is disposed on the input gear is formed as a friction force applying face which extends radially outwardly so as to be inclined downwardly. An outer peripheral portion of the idler gear slidably comes into contact with the friction force applying face.

Abstract: A rotational driving apparatus of a magnetic device, a clutch mechanism or a speed change clutch mechanism is provided selectively in a path for transmitting a rotation from a capstan motor to a feed reel or a take-up reel.

The speed change intermediate gear and speed change movable gear are mounted on a second transmission shaft provided close to a first transmission shaft, and transmit the rotation of the pulley gear to the speed change output gear via a constant torque transmission member, or directly with the speed of the rotation changed.
