装置。 A pulley and a drive gear are rotatably supported axially apart on a support shaft provided on the deck, and an arm member provided with an idler gear that meshes with the drive gear is connected to the pulley and drive gear using the support shaft. A spring is installed between the arm member and the pulley or drive gear so as to be able to swing around the support shaft, and a spring is compressed between the arm member and the pulley or drive gear to bias the arm member toward the other of the pulley or drive gear. The idler gear is brought into frictional contact with the other side of the drive gear, and the arm member is swung according to the direction of rotation by the rotation of the drive gear, so that the idler gear meshes with the driven gear provided on the supply reel stand or the driven gear provided on the take-up reel stand. let me,
A tape running device that selectively drives a supply reel stand or a take-up reel stand depending on the rotational direction of a drive gear.
