Claims

[Scope of utility model registration request]

A reel chassis equipped with a supply reel stand and a take-up reel stand is slidably disposed on a main chassis equipped with a cylinder device equipped with a rotating head and a capstan for running the magnetic tape,
In the tape loading mechanism of the signal recording and reproducing apparatus, the reel chassis can be stopped at a standby mode position where a cassette is loaded and a play mode position where a signal is recorded or reproduced.
A pinch roller lever provided with a pinch roller and a driving lever provided with a cam follower are rotatably supported on the same axis on the reel chassis, and at positions eccentric from the center of rotation of the pinch roller lever, A tape pull-out lever with a tape pull-out pin projecting thereon is rotatably supported, the pinch roller lever and the drive lever are connected to be rotatable in the same direction via biasing means, and the cam follower is mounted on the main chassis. The pinch roller lever and the tape pull-out lever are connected to each other by a link member, and as the reel chassis moves from the standby mode position to the play mode position, the drive lever A tape loading mechanism characterized in that a pinch roller lever and a tape pull-out lever rotate in the same direction.
