Amendment July 1, 1986 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] A motor capable of forward or reverse rotation; a pair of reel mechanisms rotated by the drive of the motor; a pair of capstan shafts rotated by the drive of the motor; A head base that engages with the pinch rollers and forcibly separates them from the capstan shaft; and a holding mechanism that moves the head base forward and holds the head base ; When entering the operation of rotating in the opposite direction, the holding mechanism is released and the head base is retreated;
A sound reproducing device characterized in that the pinch roller is separated from a capstan shaft.
