Claims

[Scope of utility model registration request]

A first rotating body that has a cam part and a release part and is rotated independently of the tape running, a second rotating body that is rotated in conjunction with the tape running, and the rotational force of the second rotating body It is biased in one direction, slides into contact with the cam portion of the first rotary body and swings, and when the second rotary body stops rotating, the rocking is stopped and the release portion of the first rotary body A detection member that is engaged and moved, a release member that is moved in conjunction with the detection member, and a tape running operator that can be locked in an operating position and that the tape is run while the release member is moved. a locking mechanism for unlocking the tape running operator in the operating position; and a locking mechanism for releasing the lock when the tape running operator is in the non-operating position, and the detecting member is connected to the cam portion of the first rotating body with respect to the release member when the tape running operator is in the non-operating position. A tape characterized by comprising: a φ biasing member that applies a biasing force in a direction in which the tape is pressed, and a control member that separates the release member from the detection member in conjunction with the operation of the tape running operator. Termination detection mechanism.
