[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device such as a compact disk player.

[0002]

2. Description of the Related Art The general structure of a portable compact disc player will be briefly described with reference to FIGS. In the figure, reference numeral 1 denotes a cabinet (outer case) of a compact disk player, and this cabinet 1 is configured by combining an upper cabinet 2 and a lower cabinet 3. A lid 4 is attached to the upper cabinet 2 side, and the disk mounting portion 5 is opened and closed by the lid 4. A turntable 6 and an optical pickup 7 are exposed on the disc mounting portion 5. A disc is mounted on the turntable 6 and is driven to rotate.
Reads the signal recorded on the disk.

The turntable 6 and the optical pickup 7 are disposed in one unit as a disk drive mechanism (mechanical deck) 8, that is, the disk drive mechanism 8 includes a drive motor for the turntable 6,
A feed mechanism of the optical pickup 7 and the like are configured. The disk drive mechanism 8 is swingably supported on the lower cabinet 3 at a plurality of locations via elastic bodies 9, thereby absorbing external vibration.

A circuit board 10 on which a signal reproducing circuit and other electronic circuits are mounted is fixed and supported in the lower cabinet 3. The circuit board 10 and the disk drive mechanism 8 are electrically connected by a flexible printed wiring board 11. It is connected. That is, the flexible printed wiring board 11 is led out from the disk drive mechanism 8, and the leading end thereof is connected to the connector 12 fixed to the circuit board 10, and is read by the optical pickup 7 via the flexible printed wiring board 11. Is sent to the circuit board 10,
Alternatively, a control signal is supplied to the optical pickup 7 from the circuit board 10 side.

[0005]

[Problems to be Solved by the Invention] In the conventional general portable compact disc player as described above,
The disk drive mechanism 8 is swingably supported on the lower cabinet 3 via an elastic body 9 so as to absorb vibration, that is, to secure required vibration resistance. However, as shown in FIG. An intermediate portion of the flexible printed wiring board 11 connecting the part 8 and the circuit board 10 may come into contact with an edge of the disk drive mechanism part 8, and in this case, the elastic swing of the disk drive mechanism part 8 is hindered. Vibration resistance deteriorates.

As means for preventing this, as shown in FIG. 6, a special connector 12 in which the connection direction of the flexible printed wiring board 11 is oblique is used. There is also a structure that bends so as not to interfere with the drive mechanism 8, but in this case, the connector 12 requires a special shape, so that a general-purpose connector cannot be used. That is, a special connector is manufactured as a new part. The disadvantage is that the cost is high.

[0007] The present invention has been made in view of such a point,
It is an object of the present invention to provide a disk device that does not require special parts and has a simple structure and prevents deterioration of vibration resistance of a disk drive mechanism.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, according to the present invention, a disk drive mechanism is resiliently supported by a cabinet in a swingable manner, and the disk drive mechanism and a circuit board are connected to a flexible printed wiring board. In the disk device electrically connected by the above, the cabinet is provided with a projection for pressing an intermediate portion of the flexible printed wiring board so as not to enter the swing range of the disk drive mechanism.

[0009]

According to the above construction, it is possible to prevent the flexible printed wiring board from interfering with the disk drive mechanism with a very simple construction in which only the projections are provided on the cabinet. It is possible to prevent deterioration of the vibration resistance of the disk drive mechanism without using it and without increasing the number of parts.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a first embodiment of the present invention; FIG.

In this embodiment, a plate-shaped projection 13 is provided on the inner surface of the upper cabinet 2 near the disk drive mechanism 8 so as to project downward. When the cover 2 is put on the lower cabinet 3 and united, the protrusion 13 pushes the middle part of the flexible printed wiring board 11 downward, whereby the flexible printed wiring board 11 It is structured to be held down in a greatly bent state so as to escape from the movement range.

Therefore, even if the disk drive mechanism 8 swings, the intermediate portion of the flexible printed wiring board 11 does not abut against the edge of the disk drive mechanism 8, so that when the vibration is applied, the disk drive mechanism The portion 8 swings smoothly without any hindrance and can effectively absorb the vibration, that is, the vibration resistance is kept good.

As described above, in the present embodiment, it is possible to prevent the flexible printed wiring board 11 from interfering with the disk drive mechanism 8 with an extremely simple configuration in which the projections 13 are formed on the upper cabinet 2 only. Therefore, unlike the conventional connector, it is not necessary to use a connector having a special shape, a general-purpose connector can be used, and the vibration resistance of the disk drive mechanism 8 can be prevented from deteriorating without increasing the number of components. The vibration resistance of the stable disk drive mechanism section 8 can be secured without changing the cost substantially from the compact disk player.

Particularly, in this embodiment, a structure in which the upper cabinet 2 and the lower cabinet 3 are united at the time of assembling the compact disk player so that the projection 13 automatically presses the flexible printed wiring board 11 so as not to interfere with the disk drive mechanism 8. Therefore, no special work is required to hold down the flexible printed wiring board 11, that is, stable vibration resistance can be secured without changing the number of assembling steps from a general compact disk player.

[0015]

[Effect of the Invention] As is apparent from the above description, the present invention provides a cabinet with a projection for holding down a middle portion of a flexible wiring, thereby eliminating the need for special parts and increasing the number of parts. Deterioration of vibration resistance can be prevented, and therefore, it is possible to provide a disk device having stable vibration resistance without substantially increasing cost.
