Description

[Detailed description of the invention] This invention relates to a record player in which an insulator is attached to the cabinet, bottom plate, motor board, etc. that constitute the record player body, and in particular, to simplify the attachment of the insulator to the record player body. The purpose is to

Generally, when attaching an insulator to the main body of a record player, as shown in FIG.
As shown in FIG. was fixed to the boss 5 with a mounting screw 4.

However, the above-mentioned structure has the disadvantage that the number of parts for installing the insulator 3 increases, and the number of installation steps also increases, resulting in high costs.

The present invention is intended to eliminate such conventional drawbacks, and the record player of the present invention will be described below with reference to drawings of embodiments.

Fig. 3 shows an example of the structure of the record player of the present invention, and in the figure, 11 is a cabinet that constitutes the main body of the record player, and a bottom plate 12 is provided at the opening on the bottom side of the cabinet so as to close this opening. It is being

The bottom plate 12 has a protrusion 1 having an enlarged portion 13 a at its tip.
3 is installed protrudingly.

Although not shown, the turntable, pickup arm, and other components of the record player are mounted on the upper surface of the cabinet 11, and it goes without saying that the turntable is driven by a motor.

Reference numeral 14 denotes an insulator made of a viscoelastic material such as rubber, and a vibration damper 15 made of felt or the like is provided on the bottom surface of the insulator.

The insulator 14 has a concave hole 16 into which the protrusion 13 provided on the record player body is inserted, and at the tip of the concave hole 16 there is a bulge 13 provided at the tip of the protrusion 13.
An enlarged portion 16a into which a is fitted is provided.

Here, the insulator 14 inserts the protrusion 13 on the record player main body side into the recess 16, and
The enlarged part 13a provided at the end of the protrusion 13 is fitted into the enlarged part 16a provided at the end of the protrusion 13, thereby fixing it to the bottom surface of the record player main body.

In addition to the bottom plate 12 that constitutes the record player body, the insulator 14 may be fitted onto a motor board 17 as shown in FIG. 5, or may be fitted onto a cabinet 11 as shown in FIG. Alternatively, as shown in FIG. 7, a recess 18 for fitting the insulator may be provided when the insulator is fitted and fixed to the bottom plate 12.

Further, when the insulator 14 is fitted and fixed to the record player body side such as the cabinet 11, the bottom plate 12, the motor board 17, etc., a spring 19 may be interposed as shown in FIG. 8, or as shown in FIGS. As shown in the figure, the spring 19 may be interposed in the insulator 14 in advance.

As described above, according to the present invention, a protrusion having an enlarged portion at the tip is provided protrudingly on the side of the record player main body, and this protrusion is inserted into a recess provided in the insulator to form the enlarged portion at the tip of the protrusion. Since the insulator is fitted into the enlarged part provided at the tip of the recessed hole, the insulator can be fitted and fixed to the record player body, reducing assembly man-hours, and also reducing the number of mounting parts such as screws and washers. This can significantly reduce costs.

In addition, since the enlarged part at the tip of the protrusion and the enlarged part at the end of the concave hole are mated together, the insulator can be securely attached to the record player body, and it also prevents the insulator from coming off due to loosening of the screws. Its practical value is extremely great.

Particularly, in the present invention, the ampullae is made into a spherical shape, and when the ampullae is fitted into the enlarged part provided on the insulator, substantially the entire ampullae is surrounded by the enlarged part.

Therefore, the elasticity of the insulator is applied to the entire enlarged portion, and this provides a sufficient buffering effect, so that sufficient performance can be obtained as a vibration isolator for a record player.
