Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-vibration device for a disc player that performs anti-vibration of a reproducing mechanism for reading a disc signal.

[0002]

[Prior Art]

 In a disc player such as a CD player, a drive mechanism for driving the pickup, a turntable for placing the disc, and the like are provided in order to prevent reproduction from being impossible due to external vibration being transmitted to the pickup or the disc. An anti-vibration device for isolating the reproduction mechanism is provided. Such a vibration isolator is constructed by attaching a chassis to which a reproduction mechanism is attached to a cabinet body with a vibration isolator made of an elastic material such as rubber interposed therebetween. External vibration is damped by internal loss, and the playback mechanism is isolated.

In the case of a portable CD player, the cabinet body is generally made of synthetic resin. Therefore, such a vibration isolator for a CD player has a projection such as a boss integrally formed on the bottom surface inside the cabinet body, and the vibration isolator is inserted through the projection to mount the vibration isolator on a cabinet. It is generally performed to support the main body.

[0004]

[Problems to be solved by the device]

 As the above-mentioned vibration isolator, conventionally, as disclosed in, for example, Japanese Utility Model Laid-Open No. 3-23885, a vibration isolator is fixed to a protrusion that is planted on the bottom surface of the inside of the cabinet body by using an attachment fitting such as a screw. However, there was a problem in workability.

[0007] Although the protrusions are usually open ends, they may be thick if they are thick, but for reasons such as securing a large space inside the vibration isolator due to the vibration isolation performance. Therefore, if the projections are made thinner, there is a possibility that the projections may be deformed by heat or aging, or may be damaged by a shock, which is a problem. Therefore, in order to secure the strength of the protrusion and to secure a necessary range of space inside the vibration isolator, it is necessary to make the outer shape of the vibration isolator large, and the degree of freedom in design is lost.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned points, and is constructed by forming an elastic material into a hollow structure and integrally forming it on one cabinet and a vibration isolator for elastically supporting the chassis. And a pin that penetrates the vibration isolator to support the vibration isolator, and a boss that is integrally formed in the other cabinet and that has a hole into which the tip of the pin is fitted. The boss is inserted into one end of the vibration isolator.

[0007]

[Action]

 The present invention is a disk player in which a cabinet body is formed by stacking upper and lower cabinets made of synthetic resin, and a vibration isolator for elastically supporting a reproducing mechanism is provided to support the vibration isolator. The workability is improved by integrally forming the penetrating pin in one cabinet and by forming the boss having the hole into which the tip of the pin is fitted into the other cabinet integrally. By increasing the strength of the pin so that both ends of the pin become fixed ends, a thin pin can be used, and the boss is inserted into one end of the vibration isolator. By increasing the lateral support force of the vibrating body, a highly flexible vibrating body can be used.

【Example】

FIG. 2 is a side view of a portable CD player according to the present invention, in which 1 is a cabinet body composed of an upper cabinet 2 and a lower cabinet 3 made of synthetic resin, and 4 is for opening and closing a space for mounting a disk. The lid body is rotatably supported by the cabinet body 1 .

FIG. 1 is a partial sectional view showing a main part inside the CD player of FIG. In the figure, 5 is a chassis to which a reproducing mechanism (not shown) for reading the signal of the disc is attached, and 6 is a rubber protector for elastically supporting the chassis 5 inside the cabinet body 1. It is a swing body.

The vibration isolator 6 has a central portion fitted in a hole of the chassis 5, and an upper end and a lower end thereof are supported by the upper cabinet 2 and the lower cabinet 3, respectively, and the upper cabinet 2 and the lower cabinet 2 are supported. It is interposed between the cabinets 3. Although not shown, a plurality of the vibration isolator 6 are provided so as to be arranged on each of the four sides of the chassis 5.

FIG. 3 is a development view showing a state where FIG. 1 is developed. As shown in the figure, the vibration isolator 6 has a hollow structure in which a cavity 7 extending vertically is formed. A pin 8 is erected on the inner side of the lower cabinet 3, and a ring-shaped projection 9 having a height lower than that of the pin 8 is formed around the pin 8. The pin 8 and the protrusion 9 are coaxially integrally formed with the lower cabinet 3.

On the other hand, in the upper cabinet 2, a boss 11 having a hole 10 into which the tip of the pin 8 is fitted is integrally formed toward the inside.

When assembling, first, the pin 8 is passed through the cavity 7 of the vibration isolator 6. After that, the tip of the pin 8 may be fitted into the hole 10, and this fitting is performed at the same time when the cabinet main body 1 is assembled when the upper cabinet 2 is mounted to overlap the lower cabinet 3.

In the assembled state, as shown in FIG. 1, the vibration isolator 6 is supported in a state of being installed on the protrusion 9. In the vibration isolator 6, a boss 11 is inserted into the upper end opening of the cavity 7, a pin 8 is inserted into the lower end opening of the cavity 7, and an air chamber is formed inside the vibration isolator 6. .. Therefore, the vibration or shock applied to the cabinet body 1 is attenuated by the internal loss of the elastic material (rubber) that constitutes the vibration isolator 6 and the braking by the air pressure inside the vibration isolator 6 and is transmitted to the chassis 5. Will be done. In this case, since the thickness of the pin 8 is made sufficiently smaller than that of the vibration isolator 6, the air chamber inside the vibration isolator 6 can be sufficiently secured and the vibration isolator By increasing the degree of freedom of the shape of 6, the vibration proof body 6 can be easily formed into a shape in which vibration proof performance is pursued. Since the tip of the pin 8 is fitted into the hole 10 of the boss 11, the strength of the pin 8 is increased by fixing both ends of the pin 8 to prevent the pin 8 from being damaged. You can Moreover, by inserting the boss 11 into the upper end opening of the cavity 7 of the vibration isolator 6, the lateral supporting force of the vibration isolator 6 can be increased, and the vibration isolation performance of the vibration isolator 6 can be improved. Can be done.

[0015]

[Effect of the device]

 As described above, according to the present invention, since the pin that penetrates the vibration isolator can be made thin, the vibration isolator can be easily formed into a shape pursuing anti-vibration performance. can get. Further, according to the present invention, since the boss that supports the tip of the pin is inserted into one end of the vibration isolator, it is possible to increase the lateral support force of the vibration isolator. The advantage is that the vibration damping performance of the body can be improved.
