Claims

[Scope of utility model registration request]

A take-up reel stand and a supply reel stand to which the tape reel is engaged, a pair of pad arms that press the pads that apply tape tension to both reel stands, and separate them, and rotation to the supply reel stand in normal play mode. In a tape tension applying device for a tape player that is provided with a play tension lever that applies tape tension by applying resistance, a first switching lever that switches power between a take-up reel stand and a supply reel stand. and a second switching lever that moves to one side when switching to the normal play mode, and the press-contact/separation operation of the pad arm to each reel stand is switched by the first switching lever. is,
Further, the play tension lever is driven in the tension release direction by the second switching lever in the stop mode and the fast forward mode, and is driven in the tension release direction by the first switching lever in the reverse play mode. Features: Tape tensioning device for tape players.
