Claims

[Scope of utility model registration request]

In a cassette type tape recorder having a playback function in a first direction, a playback function in a second direction opposite to the first direction, and a review function, a capstan shaft whose rotational direction is switched in accordance with the playback direction. and a rotary board which is rotatably attached to the fixed board by a rotation center shaft and which is displaced from the stop position to the playback operation position during the playback operation and from the playback operation position to the review operation position during the review operation. , is rotatably attached to a rotation center shaft fixed to the rotary base plate, is pressed against the capstan shaft when the rotary base plate is in the playback operation position, and is spaced apart from the capstan shaft when the rotary baseplate is in the review operation position. a head board which is rotatably mounted on the central axis of rotation and is rotatably displaced to each operating position in response to the playback direction; and a pinch roller on the head board. A first magnetic head and a second magnetic head are arranged on both sides and are fixed at positions far from and near the rotation center axis, and the head substrate is rotatably displaced by the reproduction direction switching operation. a head switching member that controls the displacement operation of the head;
a rotary board control member that is displaced during a review operation and displaces the rotary board to a review operation position, and when a review operation is performed while the first magnetic head is in a reproducing operation state, the rotary board control member When the first magnetic head is moved to the review position by displacing the rotary board to the review operation position, and when the review operation is performed while the second magnetic head is in the reproducing operation state, the rotary board control member causes the rotation board to move. 1. A magnetic head switching device for a cassette type tape recorder, characterized in that the second magnetic head is moved to the review position by a control operation of the head switching member while the moving board is moved to the review operation position.
