Claims (1)

[Claims for Utility Model Registration] 1. A tape loading device configured to pull out the tape in a tape cassette by a loading means and load it onto a tape running path, a tape guide arm having a tape guide at its tip. is rotatably attached to a movable member, the tape guide is configured to be movable by the movable member in a direction substantially perpendicular to the loading direction of the tape by the loading means, and the tape guide is rotatably driven by a motor to A driving side partially toothed gear that drives the moving member, and a driven side partially toothed gear that is driven by the driving side partially toothed gear and rotationally drives the tape guide arm with respect to the moving member, and the loading means After loading the tape, the movable member is driven by rotation of the partially toothed gear on the driving side to insert the tape guide inside the loop of the loaded tape, and the subsequent driving The continuous rotation of the side partially toothed gear drives the driven side partially toothed gear to rotationally drive the tape guide arm, so that the tape guide stretches a part of the tape to a predetermined position. A tape loading device characterized by: 2. The tape guide arm is rotatably attached to the movable member by a rotating shaft, a part of the rotating shaft is configured as a non-circular shaft, and the tape guide arm is disposed on the driven side from the driven side partially toothed gear and held in a fixed position. A non-circular hole is provided in the center of the driven rotary body that is rotated by the rotation, and the non-circular shaft is slidably inserted into the non-circular hole, so that the rotational force of the driven rotary body is transmitted to the non-circular shaft. 2. The tape loading device according to claim 1, wherein the non-circular shaft is configured to be able to slide in the axial direction with respect to the driven rotating body in a state where the tape loading device is in a state where the non-circular shaft is slidable relative to the driven rotating body.
