向切換装置。[Scope of Claim for Utility Model Registration] (1) A supply side where a pair of left and right capstans are driven to rotate in opposite directions by a travel motor and engage with the supply side reel and take-up side reel of the tape cassette, respectively. with a hub on the winding side and a hub on the winding side, one on the left and one on the left.
In a tape recorder configured such that a selected one of the pair of pinch rollers contacts the capstan and a take-up reel is driven, a pair of left and right rotating arms are provided to be swingable to the chassis; an intermediate gear that rotates in conjunction with the capstan and is pivotally supported by each rotating arm;
A pair of left and right pinch roller arms that pivotally support the pinch roller and are swingably provided to the chassis;
A running direction switching plate that is slidably provided to the chassis, and a running cam mechanism that is installed on the running direction switching plate and the rotating arm to move the rotating arm so that the intermediate gear meshes with the hub gear on the winding side. and an engagement member that engages with the running direction switching plate to move the pinch roller arm to the pinch roller contact position. (2) The moving operation of the pinch roller arm by the engaging member is configured to be performed in conjunction with the positioning arm on the side that is not meshed with the intermediate gear. Tape running direction switching device.
