Claims

[Scope of utility model registration request]

In a full-width erasing head located between two tape guides and arranged so that the necessary tape wrapping angle is obtained by these two tape guides, a shaft fixed on the base and a shaft fixed to this shaft are connected. a first arm which is swingably inserted and carries the full-width erasing head thereon; a spring means for biasing the first arm in one direction; and a required clearance between the first arm and the first arm. a second arm connected with
comprising a drive source for swinging the second arm and a stopper means for the first arm, when the first arm is rotated by the spring means when the drive source is not operating; The tape is stopped by the stopper means, and at this time, the tape is wound around the full-width erasing head by a necessary wrapping angle, and when the drive source is in operation, the full-width erasing head is configured to rotate to a position where it does not come into contact with the tape. Full-width erase head drive.
