リード線処理を行な″う方法が知られている。Conventionally, in this type of device, the lead wire that transmits signals from the magnetic head is inserted through a hollow part of the rotating shaft and pulled out to the outside of the back surface, or the lead wire is wound around a rotating member that rotates together with the rotating shaft or the head. There is a known method of processing the lead wires by attaching them and pulling them out to the outside of the side.

半田付部の寿命に課題があった。Problems to be Solved by the Invention However, in the above-mentioned conventional method, as the number of rotations of the head increases, wear occurs at the location where the head 20 of the FPC 19 contacts the FPC end surface 19c inside the FPC wrapping portion 19a. Since the exit from the FPC is pulled only from the direction of the FPC wrapping part 19&, torsional stress is generated at the exit, which poses a problem in the lifespan of the FPC and head soldering part.

巻付けられている。Further, the FPC 29 connected to the head 20 is bent 90 degrees at the exit of the head mount 21, passed through the opening 23a of the rotating body 23, and the wrapped portion 29a of the FPC is rotated 180 degrees to the drum portion 23b of the rotating body 23. It is wrapped with the necessary margin.

７に固定する構成となっている。At the exit from the head mount 21, the FPC 29 is attached to the winding part 2.
A protrusion 29c is provided on the side opposite to 9a, and the inner side of the wrapped portion 29a presses the surface of the protrusion 29c when it is wound. Furthermore, the FPC end 29b is attached to the head base 2.
It is configured to be fixed at 7.

状態のトラノク位置となる。When the button is pressed in FIG. 2, the drive gear 28 assumes the position (A) due to the elasticity of the FPC 29 in its initial state.
(not shown), rotates at position 1 (b), and in conjunction with this, the rotating body 23 rotates 180 degrees while winding up the PFC 29, and reaches the position shown in FIG. 2. At this time, the head tracks rotates from point to point with respect to the center of rotation, and changes from a normal rotation state to an inverted state.

半田付部の寿命を長くすることができる。As described above, by providing the projection 29a on the FPC as in this embodiment, the winding portion of the FPC can be formed as shown in FIG. 4, 19c.
Since it does not contact the FPC end face but contacts the surface of the protrusion 29c, the inner side of the wrapped portion 29a does not wear out even if the number of rotations increases. Further, at the exit from the head mount 21 of the FPC 29, stress is applied in the direction of the FPC wrapping part 29a as the head 20 rotates, but at the same time, the protrusion 29c also receives stress from the wrapping part 29.
Since the stress is applied from inside a, torsional stress is not applied at the exit portion, so the life of the FPC 29 and the soldered portion to the head terminal can be extended.
