Description

[Detailed description of the invention] The invention is based on a first
The present invention relates to an improved structure of a turntable sheet to be placed on a record turntable, which has a turntable and a second turntable held to the first turntable via an elastic or viscoelastic substance.

The turntable for records as described above is conventionally known as disclosed in, for example, Japanese Utility Model Publication No. 31-2342.

The structure of the turntable described in this publication is as shown in FIG.
The first turntable 2 is loosely fitted to the turntable shaft 1, and the second turntable 6 is fixed to the first turntable 2 via an elastic or viscoelastic substance. This is what I did.

In this case, as can be seen in the drawings, since the diameter of the first turntable 2 is smaller than the diameter of the second turntable 6, it is possible to play an arbitrary piece of music such as a record placed on the second turntable 6. For cue selection, use elastic body 5.
When the second turntable placed on the table is rotated by hand, a downward force is applied to the elastic or viscoelastic material 5, causing the second turntable to tilt and rotate the record in a horizontal state. However, it has the disadvantage of producing abnormal sounds from speakers, etc.

A second turntable device that eliminates the above-mentioned drawbacks.
The applicant previously proposed a device as shown in the figure.

That is, the first turntable 2 is loosely fitted to the turntable shaft 1 as one unit with a bearing 3, for example, and the second turntable 6 is connected to the first turntable via an O-ring 4 and an elastic body or a viscoelastic substance 5. The second turntable is fixed to a turntable, the turntable sheet γ and the record 8 are placed on the second turntable, and the second turntable is placed inside the first turntable. The first turntable was rotated by hand so that the outer circumference 9 of the second turntable was larger than the diameter of the second turntable and rose to the top of the second turntable. When cuing up the record, the second turntable can be rotated without touching it, so the record can be rotated horizontally.

Furthermore, the frictional vibrations caused by the hands are attenuated by the elastic or viscoelastic body interposed between the first and second turntables, making this structure extremely useful for cueing, etc.
This configuration has the disadvantage that vibrations generated when turning the turntable by hand are transmitted to the second turntable 6 through the turntable sheet 7 during cueing.

The present invention is a turntable sheet 7 that eliminates the above-mentioned drawbacks.
The present invention will be explained with reference to FIG.

As is clear from the figure, the first turntable sheet 10 is placed on the outer periphery 9 of the first turntable full 2, the second turntable sheet 11 is placed on the second turntable full, and the first and second This is a structure in which a gap 12 is formed between the turntable sheets.

In this way, even if the outer circumference of the first turntable 9 is turned by hand, the vibrations transmitted to the second turntable 6 via the turntable sheet are completely blocked because the turntable sheets are separate and not integrated. You can.

The first turntable sheet in the above structure has little vibration effect, but as mentioned above, operations such as cueing are performed on the upper surface of the first turntable 9, that is, on the first turntable sheet. For this reason, conventional turntables that use aluminum-based materials are anodized or coated with paint, but when anodized, there are many uneven colors. Also, it is easy to get fingerprints, etc., which will turn into rust over a long period of time.

Furthermore, in the case of painting, it has the disadvantage of peeling off over a long period of time, which impairs the aesthetic appearance of the product.

Since the present invention has the first turntable sheet adhered to the first turntable, it has the same structure as the conventionally used rubber sheet, and does not rust or peel. There is little sense of discomfort, and as mentioned above, unnecessary vibrations can be eliminated, and the practical effect is good for dogs.
