。[Claims for Utility Model Registration] A first arm member having a pinch roller attached thereto and configured to be freely rotatable, and a driven member that engages with and is driven by a cam plate that is driven during tape loading. and an engaging portion that engages with the first arm member, the second arm member being rotationally displaced via the driven portion as the cam plate is displaced; A spring member is disposed between the second arm members and biases the first arm member and the second arm member to rotate in opposite directions, and the tape roller When the engaging portion engages with the first arm member during the dewing operation, the spring means restricts the rotation of the first arm member, and the first and second arm members engage with the first arm member. The first arm member is configured to integrally rotate due to displacement, and when the pinch roller comes into contact with the capstan shaft, the first arm member is separated from the engagement portion, and the spring member is configured to rotate the second arm member. A pinch roller drive mechanism configured to press the pinch roller onto the capstan shaft by a rotationally biasing force.
