Abstract

PURPOSE:To provide the vibration proof device having excellent workability and performance by solving the problem of the poor mounting workability and performance of the vibration proof device to be interposed between the body part and external chassis part of an information reproducing apparatus. CONSTITUTION:This vibration proof device is constituted by interposing the vibration proof elastic member 8 molded internally and integrally with a coil spring 7 in a gravity direction between the external chassis part 1 and the body part 2. The assembly workability of the vibration proof device is improved in this way and the excellent performance to absorb and attenuate disturbing vibrations is obtd.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration isolator for an information device equipped with a recording / reproducing pickup drive such as a compact disc player and a magneto-optical recording device.

[0002]

2. Description of the Related Art In recent years, vibration resistance of an information reproducing apparatus equipped with a recording / reproducing pickup drive has been required.

A conventional vibration damping device will be described below.
2 and 3 show a conventional vibration damping device. In the figure, a main body 2 having an information reproducing drive built therein is formed inside an external chassis 1. A vibration-proof elastic member 4 having a coil spring 3 mounted on the outer circumference is interposed between the outer chassis 1 and the main body 2. The outer peripheral portion of the vibration-proof elastic member 4 is fitted into the concave groove portion 5 of the outer chassis portion 1, and the lower portion is attached with the main body portion 2 on the screw 6.

The operation of the vibration-proof mechanism having the above-described structure will be described below. Vibration received from the outside by the external chassis portion 1 is absorbed and damped by the coil spring 3 and the vibration-proof elastic member 4, and when the main body portion 2 reproduces information, the influence of the external vibration is reduced and stabilized.

[0005]

However, in the above structure, since the coil spring 3 and the vibration-proof elastic member 4 are separate members, workability is poor when the external chassis 1 is attached to the main body 2, and the coil spring 3 is not provided. There is a problem in that if the is installed in a tilted position, there will be variations in performance, and vibrations from the outside will not be absorbed or dampened sufficiently, resulting in an adverse effect on the accuracy of reading information.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a vibration isolator having good workability.

[0007]

To achieve this object, a vibration isolator of the present invention has a structure in which a coil spring and a vibration isolating elastic member are integrally molded.

[0008]

With this structure, since the coil spring and the vibration-proof elastic member are integrated, the workability of incorporating the external chassis portion into the main body portion is facilitated, and the quality control can be performed as an integrally molded member. ， The damping performance can be stabilized.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 1, the coil spring 7 is integrally formed inside the vibration-proof elastic member 8. The lower end portion of the vibration-proof elastic member 8 is fitted into the hole 9 of the main body portion 2, and the upper end portion thereof is fitted into the annular protrusion 10 of the outer chassis portion 1, and then attached to the outer chassis portion 1 with the screw 11. The vibration-proof elastic member 8 is arranged between the outer chassis 1 and the main body 2 in the direction of gravity.

The operation of the vibration isolator constructed as above will be described. External chassis 1 and body 2
The anti-vibration elastic member 8 interposed in the direction of gravity mainly absorbs the disturbance vibration in the direction of arrow A, which is the direction of gravity, by the coil spring 7 and attenuates the vibration by the other elastic portions. The disturbance vibration in the direction of arrow B, which is the direction perpendicular to the direction of gravity, is mainly absorbed and damped by elastic portions other than the coil spring 7.

[0012]

As described above, according to the present invention, the vibration-proof elastic member interposed between the external chassis portion and the main body portion in the direction of gravity is provided.
Since it is molded integrally with the coil spring, the workability of incorporating the external chassis into the main body is good, and since it is possible to control the quality as an integral part, there is no variation when incorporating and the vibration isolation performance is stable and information is reproduced. Stable performance with little influence of external vibration.
