PURPOSE:To control easily and accurately the position of a head, by holding rotatably the 1st head substrate containing a fixed head at the 2nd head substrate having a controllable control part and at the same time energizing the 1st head substrate toward the control part. CONSTITUTION:When a tape is loaded, the guide posts 7, 8, 10 and 11 move to the position of a solid line from the position of a 2-dot chain line. While an audio head 14 and postrecording erasion head 13 move to the positions of solid lines to the positions of 2-dot chain lines respectively. The heads 13 and 14 are fixed at a substrate 26, and the substrate 26 is attached to a rotary lever with screws 23 and 24 and a set screw 25. A rotary lever 22 can turn round a shaft 29 fixed at a rotary lever 21 and is energized toward the lever 21 by a torsion coil spring 27. The heads 13 and 14 are turned round the shaft 29 by turning a set screw 28 having its tip touching the lever 22. Thus the position of the head can be easily controlled. |
