Description

[Detailed Description of the Invention] The present invention relates to a wire bundling device for a magnetic head, and more specifically, the spring for adjusting the thrust of a magnetic head is improved so that it can also be used as a wire bundling device for a magnetic head. be.

FIG. 1 shows the area around the magnetic head of a conventional tape recorder. The magnetic head 2 is placed on a magnetic head support plate 3, and one end of the support plate 3 is attached to a movable chassis 1 with a screw 5 through a spacer 4. The other end is attached to the movable chassis 1 with a screw 7 via a spring 8 and a spring receiver 6 so as to be vertically adjustable.

However, since the movable chassis 1 normally moves between a stopped state and, for example, a recording or playback state, if the wires 12a, 12b connected to the terminals 2a, 2b, 2c, 2d of the magnetic head 2 are left as they are, the movable chassis 1 Each time the magnetic head 2 is moved, the connecting portion between the magnetic head 2 and the wires 12a and 12b is bent or bent, which poses a risk of a disconnection accident. Therefore, a commonly used countermeasure is to bundle the wires 12a, 12b, etc. connected to the magnetic head 2 with a bundle band 9, and then fix them on the movable chassis 1 with a screw 11 via a spacer 10 so that the wires can be moved. Even if the chassis 1 moves, no unnecessary force is applied to the wires 12a, 12b, etc. Therefore, with these devices, a member for independently bundling wires and screws and spacers for fixing the wire bundle member on the movable chassis are required, which not only increases cost but also requires a mounting spacer. Therefore, the movable chassis becomes large, which is particularly disadvantageous for small equipment.

The present invention has been made to eliminate the above-mentioned drawbacks, and is a novel magnetic head in which the thrust adjustment spring disposed between the magnetic head support and the movable chassis is also used as the wire bundle member of the magnetic head. The present invention will be described below in detail with reference to an embodiment shown in FIG. 2. In FIG. 2, the same parts as in the conventional example shown in FIG. The other end is attached to the movable chassis 1 using a spring 13, a spring receiver 6, and a screw 7 so as to be vertically adjustable.One end of the spring 13 is extended to form a ring-shaped wire. A wire bundle portion 13a is formed, and this wire bundle portion 13a connects the terminal 2 of the magnetic head 2.
It is possible to elastically and effectively bundle the wires 12a, 12b, etc. connected to wires 12a, 2b, 2c, 2d. Therefore, even if the movable chassis 1 moves, the connecting portions between the magnetic head 2 and the wires 12a, 12b do not move, and accidents such as disconnection can be prevented.

As described above, the magnetic head bundle device of the present invention improves the thrust adjustment spring disposed between the magnetic head support plate and the movable chassis to form a wire bundle portion, so it is different from the conventional wire bundle device. This eliminates the need for wire bundle bands, screws, spacers, etc. for fixing them, which is not only advantageous in terms of cost, but also makes it possible to downsize as there is no need to provide mounting spacers on the movable chassis. Furthermore, since the wires can be elastically bundled and supported, there is no risk of damaging the wires, and so on.

In the above embodiment, a ring-shaped wire bundle part 13a was formed at one end of the spring 13, but as shown in FIG. A spring 14 having a wire portion 14a may be used, and wire bundle portions 15a and 15b may be formed at both ends of the spring 15 depending on the number of wires to be bundled, as shown in FIG. Needless to say, it is fine to do so.
