Claims

[Scope of utility model registration request]

(1) In a device for moving a composite magnetic head composed of a magnetic reproducing head and a magnetic recording head used in a magnetic recording/reproducing device, A. The composite magnetic head and the erasing head are mounted and moved toward and away from the magnetic tape surface. B. two pairs of heads mounted on the chassis so that the head substrate can select two consecutive left and right positions when the composite magnetic head and erasing head mentioned above come into contact with the magnetic tape; A substrate guide member and C are provided so as to be movable approximately parallel to the running direction of the magnetic tape in contact with the above-mentioned composite magnetic head and erasing head, and are engaged with the head substrate at one end to select the head substrate left or right. a selection drive plate to be moved; D a spring for the selection drive plate that elastically biases the selection drive plate so that it is always moved in one direction when no external force is applied to the selection drive plate; E an engaged member provided on the selection drive plate. Gobe and F
The magnetic recording/reproduction switching lever is actuated by a magnetic recording operation and engages or comes into contact with the above-mentioned secured portion to move the selection drive plate against the elastic force of the selection drive plate spring. A head substrate moving device characterized by:

(2) A head substrate moving device according to the utility model registration claim set forth in item (1), characterized in that the magnetic recording/reproducing switching lever described above is linked to a recording operation button and can be manually switched.

(3) The utility model registration claim set forth in paragraph (1) is characterized in that the magnetic recording/reproduction switching lever described above is switched by a recording operation button or by driving an electromagnetic solenoid for recording operation operated by a recording operation signal. head substrate moving device.

(4) In the scope of the utility model registration claim set forth in paragraph (1), the above-mentioned magnetic recording/reproduction switching lever is triggered via a drive member such as an electromagnetic solenoid by the edge operation button or edge operation signal to drive the flywheel. A head substrate moving device characterized in that the recording operation lever is operated stepwise or by the rotation of a cam plate using the power of a dedicated drive motor and a rotation angle indicating device using a potentiometer.
