Description

[Detailed Description of the Invention] The present invention relates to a player in which a record disc or the like is attracted to a turntable.

Conventionally, instead of a stabilizer, there are stabilizers that allow the record to be sucked onto the turntable.For example, there are stabilizers that allow the record to be sucked by pressing it against a plurality of suction cups on the turntable, and stabilizers that allow the record to be sucked by pressing the record against a plurality of suction cups on the turntable. There are known devices in which the record is sucked onto the turntable by vacuuming it through a suction hole provided in the rotary shaft.

However, the former has problems with the suction holding power and the stability of the record, and the latter not only has a complicated structure, but also has difficulty in suction holding power, and it is necessary to increase the suction holding power. If the vacuum pump is used with an electric pump, it has the disadvantage that air noise is generated even during play, giving an unpleasant feeling.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to provide a player that can accurately attract a disc to a turntable with a simple structure and has excellent suction and holding power.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 indicates a turntable, and 2 indicates a record disc. Reference numeral 3 denotes a bellows-shaped suction pump, which is attached to the outer peripheral wall of the turntable 1 in a ring shape. A suction hole 5 is formed so as to penetrate from the empty chamber 4 of the suction pump 3 to the disk mounting surface of the turntable 1, and the record 2 can be set on the turntable with the suction hole pump 3 compressed. By releasing the compressed state of the suction pump 3, the self-restoring force of the bellows causes the record 2 to be attracted.
Reference numerals 6 and 7 are inner and outer suction valves provided in a ring shape on the disk mounting surface of the turntable 1, and mounting grooves 8 and 9 are provided on the inner and outer circumferences of the turntable 1.
is formed into a ring shape, and suction valves 6 and 7 made of ring-shaped rubber or the like with a thinned outer circumferential tip are installed in the mounting grooves 8 and 9 to seal the turntable surface and the record surface. It is. Since a small gap a is formed between the turntable 1 and the record sound groove surface, the suction hole 5 may be provided at one location, but a plurality of suction holes 5 may be provided at intervals.

Reference numeral 10 denotes a pressing member which is disposed on the side of the turntable 1 and is movable toward the center of the turntable 1, and which compresses the suction pump 3 by moving forward. An arcuate pressing plate 12 is provided at the tip of the shaft 11 that moves forward and backward, and is provided in three directions.

Although the illustrated example shows an electromagnetic plunger 13 as a mechanism for advancing and retracting the pressing member 10,
It goes without saying that this may be a fluid pressure pump, and it may also be configured such that each of the pressing members 10 is moved forward and backward by an operating lever.

According to the player of the present invention, a bellows-shaped suction pump is attached to the outer peripheral side wall of the turntable, and after compressing the pump, the disc is attracted to the turntable through the suction hole, so the construction is extremely simple. Unlike turntables that have suction holes in their rotating shafts, D and D motors can be used, and the system uses the self-restoring force of the bellows of the suction pump, so there is no air noise when playing. Especially since the suction pump is bellows-shaped,
Moreover, since it is attached to the outer peripheral side wall of the turntable, a large vacuum space can be created.
Great adsorption power can be obtained.

The pressing member that compresses the suction pump is placed on the side of the turntable so that it can move forward and backward, and when it moves forward, it compresses the suction pump, and when it moves backward, it retreats from the turntable, so of course it does not cause any trouble during play. After playing, it can also be used as a brake device for the turntable by moving it forward.
