[Detailed description of the invention]

[0001]

INVENTION The present invention relates to a vibration mechanism of the device such as a disk pre-over ya.

[0002]

BACKGROUND ART Figure 5 Dimensions of the in-vehicle disk pre chromatography Ya (figure and in which: FIG.), And the disk such as a compact disc (CD) is the disc tray 1
01, and the disc trays 101 are magazine magazines
The magazines are stacked and stored in
Over scan 102 is inserted into the insertion opening 104 of the disk pre over ya 103.

[0003] In the disk pre chromatography Layer 103, the disc tray 101 is pulled out to the play position by one, recording is reproduced by the optical pickup or the like.

[0004] The disk pre over ya 103 is capable of two ways when the vertical installation of the insertion port 104 is directed upward, which is horizontally disposed as in FIG. 5, one is selected on account of the vehicle structure You.

Meanwhile, the disk pre over ya 103 to receive the vibration of the vehicle, it is a vibration Organization, generally the instrument housing, the internal mechanism portion is a suspended state by a spring (not shown).

FIGS. 6 (a) and 6 (b) are diagrams showing the principle of a conventional vibration-proof mechanism , and FIG.
The internal mechanism 105 is suspended from above by springs 107 and 108. Also, FIG. 6 (b) shows the disk pre chromatography Ya 103 vertically installed, the internal mechanism portion 105 is also suspended above to the spring 108 and 109.

[0007] FIG 6 (a), the disk pre chromatography <br/> Ya 103 (b) is the same article, the horizontal installation and vertical installation 6
The structure is such that the spring 107 shown by the imaginary line in FIG.

[0008]

However, the work of re-engaging the spring is generally performed by the left lid 103a and the right lid 103b shown in FIG.
6A, the spring 107 in FIG. 6A is removed, and the spring 107 is re-hung to the position of the spring 109 in FIG.
Will be fitted with 03b, this troublesome work since the be made the vehicle menu over mosquitoes and di over La or vehicle purchaser is an accepted side, it will be forced to unnecessary work burden.

[0009] In order work is troublesome, without thorough a set replacement of the spring, while the spring sets of horizontal installation, vertical installation (or vice versa) is, the bad the internal mechanism of the disk pre over ya It can also give a page . Therefore, an object of the present invention is to provide a vibration-proof mechanism that can change a horizontal specification to a vertical specification (or vice versa) with a simple operation.

[0010]

In order to achieve the above object, the present invention provides first, second, third and fourth arrangements arranged in a substantially X-shape.
A pivoting lever having one end locked to the internal mechanism and the other end pivotally attached to the housing by approximately 90 °, with a spring and a vertically oriented fifth spring connecting the internal mechanism to the housing; It is characterized by being attached to.

[0011]

In accordance with the direction of the housing, the turning lever is turned by about 90 ° to make the fifth spring vertical.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings should be viewed in the direction of reference numerals.

FIG. 1 is an exploded perspective view of a disc player according to the present invention. The apparatus of the present invention will be described by taking a disc player as an example. The disc player 1 has side plates at both ends of a bottom plate 2 via corner members 3. 4 and 4 (the members on the left side are omitted for convenience of the drawing space; the same applies hereinafter). The top plate 6 is further passed through the corner members 5 and 5, and the back plate 7 is closed. a housing 8, resistance of the present invention in the interior of the casing 8
And an internal mechanism 9 held in a suspended state through the vibration mechanisms 10 and 10. The anti-vibration mechanism 10 includes an arc groove 11 of the side plate 4, a turning lever 12 inside the side plate 4, a fixed plate 13 inside the same, a moving plate 14 inside the same and supporting the internal mechanism section 9, the fixed plate 13 and the moving plate 14 and a fifth spring 19 connecting the fixed plate 13 and the movable plate 14 via the turning lever 12. First to fifth springs 15
19 will be described in detail with reference to FIG. The movable plate 14 is movable with respect to the housing 8, and the fixed plate 13 is substantially fixed to the housing 8.

FIG. 2 is an exploded view of an anti-vibration mechanism of the device according to the present invention.
The front ends of the fixing members 17 and 18 pass behind the fixing plate 13 and are locked at four corners of the fixing plate 13. In the center of the fixed plate 13, the swivel lever 12 is screwed so as to be able to swivel, and a fan-shaped hole 13b corresponding to a fan shape drawn with a divergence angle of about 90 ° around a tap 13a for the screw is punched out. ing.
The revolving lever 12 is a substantially semicircular plate, and one end of the fifth spring 19 is hooked on the upper part when the elliptical hole 12a is viewed from the tap 13a and the semicircular chord is horizontal. This fifth spring 19
Extends downward behind the swivel lever 12 and extends through the sector hole 13b.
And is locked to a spring locking piece 14a substantially at the center of the moving plate 14. The turning lever 12 is also provided with a tap 12b, and a stop bolt 20 screwed into the tap 12b moves in the arc groove 11 of the side plate 4.

The operation of the anti-vibration mechanism of the device having the above configuration will be described. FIG. 3 is a state diagram when the anti-vibration mechanism of the present invention is set to the horizontal specification, and corresponds to a configuration in which the configuration of FIG. 2 is assembled as it is. The movable plate 14 is suspended by first to fourth springs 15 to 18 on a fixed plate 13 which is substantially fixed to the housing 8. In this state, only the upper first spring 15 and the fourth spring 18 carry out the lifting action, and the movable plate 14 is free to move down.
4 is always raised. Thus, the moving plate 14 supporting the internal mechanism 9 is held at a predetermined position,
Even if the housing 8 vibrates, the internal mechanism 9 is well protected by the damping (damping) action of the first to fifth springs 15 to 19.

FIG. 4 is a state diagram when the anti-vibration mechanism of the present invention is of a vertical type. First, the housing 8 is raised as shown by the arrow, and then the locking bolt 20 is loosened, and the bolt 20 is moved by about 90 ° as shown by the arrow. Specifically, the arc groove 11 of FIG.
From one end to the other. FIG. 4 shows a state in which the fixing bolt 20 is fixed at that position. In FIG. 4, the movable plate 14 is pulled up by the third spring 17 and the fourth spring 18,
In addition, the movable plate 14 is lifted by the fifth spring 19.
Is held in place.

H (horizontal meaning) and V (vertical meaning) are specified in the arc groove 11 of the side plate 4 in FIG.
The position of 0 can be confirmed from outside.

[0018] Incidentally, although this embodiment describes the disk pre chromatography Ya as an example, device 1 is not limited to this, widely present invention the vibration mechanism in an electronic device such as the mechanism portion in the interior of the housing is supported by a spring Can be applied. Also, stop bolt 2
0 includes screws and small screws with + or-cut in the head, and the shape is arbitrary.

[0019]

[Effects of the invention] As described above, the present invention
The vibration mechanism of a device, such as over Ya, constituted by first, second, third, fourth fifth spring spring and vertical orientation which are arranged in a substantially X-shaped,
Since the fifth spring can be redesigned, it is easy to change the spring setting from horizontal installation to vertical installation (or vice versa).

[0020] Therefore, according to the present invention, the work load of the receiving party of the equipment such as a disk pre chromatography <br/> ya is very light, it can be prevented damage to the disk pre-over Layer due to setting errors of the spring .
