Claims

[Scope of utility model registration request]

a pair of reel stands that drive tape reels;
A pair of gears that rotate together with the reel stand, a drive gear located between the two gears, and a swinging arm that is swingably supported by the same shaft as the drive gear.
In a tape player drive device that is provided with an idle gear that is attached to a swing arm and meshes with the drive gear, the idle gear is supported without providing a rotational load applying mechanism to the swing arm. 1. A drive device for a tape player, further comprising a switching member for moving the idle gear to a position where the tips of the teeth are in contact with the gear on the reel stand side.
