Claims

[Scope of utility model registration request]

(1) In a tape recorder device equipped with a forward/reverse switching mechanism for switching the tape between forward and reverse constant speed running states,
A head slider that slides in a predetermined direction in conjunction with the switching operation of the forward/reverse switching mechanism, and a single recording/reproducing head, a recording head, a playback head, and an erasing head supported by the head slider, respectively, for each tape. A head support that supports a protruding contact surface, and
The RAD support is rotated in conjunction with the switching operation of the forward/reverse switching mechanism, with the tape contact surfaces of the pre-recording/re-recording head, the recording head, the reproducing head, and the erasing head facing the tape. A head rotation mechanism including a mechanism for rotationally moving a pre-recording/reproducing head or a recording head, a reproducing head, and an erasing head is provided at two positions corresponding to constant speed traveling in the reverse direction, and is protruded from the head support body. A tape recorder apparatus characterized in that the height of the erasing head is lower than the height of the previous recording/reproducing head, the recording head, and the reproducing head.

(2) The upper recording/rewriting head and the erasing head are arranged in parallel on the head support along the tape running direction, and at least the tape contacting surface of the former recording/rewriting head is curved along the tape running direction, and the The tape contacting surface of the erasing head is located closer to the tape than the tangent of the tape contacting surface of the recording/reproducing head on the side adjacent to the erasing head. The tape recorder device according to item 1.
