る。(Example) The present invention will be explained below according to the example shown in FIGS. 2 and 3. First, a shaft 11 is fixed to the chassis 10 as in the conventional case. A substantially L-shaped mounting base 12 is attached to the shaft 11, and a coil spring 13 is fixed with a mounting nut 14. The mounting base 12 is made up of a cylindrical part 15 that is fitted with the shaft 11 and a plate-like part 16, and a magnetic head 18 is attached to a screw 1 on the upper side of the plate-like part 16 via a plurality of fixing bases 17, 17.
9, 19... On the other hand, a convex portion 20 and a pin 21 are provided on the lower side, and this pin 21 is inserted into a through hole 22 formed in an arc shape in the chassis 10 to restrict the rotation range. . Further, the chassis 10 is provided with a protrusion 23 corresponding to the protrusion 20 described above. Then, when the mounting base 12 is rotated to the position shown in FIG. Convex portion 2 provided
3, the mounting base 12 is pushed slightly upward against the force of the spring 13 and positioned. Incidentally, positioning in the horizontal direction is performed by a spring (not shown) as in the conventional device.
