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. moving the composite magnetic head and erasing head to approach and separate from the magnetic tape surface; B. an auxiliary head provided on the main head substrate, on which the above-described composite magnetic head is placed, and which is movable in parallel to the magnetic tape running direction of the above-described magnetic tape surface; a substrate; C1; an auxiliary head substrate spring for resiliently repelling the gap between the auxiliary head substrate and the main head substrate ii1 to bias the composite magnetic head described in ii1 in the magnetic tape running direction and move it in one direction; D. E. A contact portion provided on the auxiliary head substrate; A composite magnetic head moving device comprising a magnetic recording/reproduction switching lever for moving the composite magnetic head.

(2) A composite magnetic head 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) In the utility model registration claim set forth in paragraph (1), the magnetic recording/reproduction switching lever described above is switched by a recording operation button or an electromagnetic solenoid for recording operation activated by a recording operation signal. Composite magnetic head moving device.

(4) In the scope of the utility model registration claim set forth in paragraph (1), the previously struck magnetic recording/reproduction switching lever is triggered by a recording operation button or a recording operation signal via a driving member such as an electromagnetic solenoid to drive the flywheel. What is claimed is: 1. A composite magnetic head moving device characterized in that the recording operation lever is operated stepwise or by rotation of a cam plate using the power of a dedicated drive motor.
