JPS5832202A - Cleaning device of record disk - Google Patents

Abstract

PURPOSE:To clean a record disk without damaging the label surface, by setting the record disk between a rotating plate at an edge of an exclusive table and a rotary driving plate of a cleaner and turning the record disk while detaining the cleaner with a detaining frame provided at the other edge of the exclusive table. CONSTITUTION:The center hole 10a of a record disk 10 is fitted to a guide pin 2 of an exclusive table 1, and the disk 10 is put on the table 1. A record cleaner main body 6 is set by fitting a hole 31 of a rotation driving plate 7 to the pin 2 and at the same time detaining the free and of the main body 6 to a detaining frame 4 of the table 1. A motor 11 conducts with push of a switch button 8, and the motive power of the motor 11 is transmitted to a rotating brush 18 via a belt 17 and a rotating shaft 14 as well as to the plate 7 through a pulley 28 provided to an end of the shaft 14. The disk 10 is turned with the rotation of the plate 7. Thus the dust stored in the sound groove of the disk 10 is moved up with the rotation of the brush 18 and sucked into a dust case. In such way, the even cleaning of a disk 10 is possible without damaging the lebel surface of the disk 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a record cleaning device.

Conventional record cleaning devices clean the record by keeping the record stationary and rotating a record cleaner body equipped with a rotating brush. The amount of contact between the tip of the bristles of the rotating brush and the sound groove of the record is unstable due to the warping of the disc, and as a result, the cleaning performance varies markedly depending on the record. If the record cleaner itself runs above the record,
It also had the disadvantage of causing scratches on the label surface.

In view of the above-mentioned conventional drawbacks, the present invention positions a record disc between a rotary plate that is freely rotatable through a guide pin provided at one end of a dedicated table and a rotary drive plate of a record cleaner main body, and that a record disc is positioned between a rotary plate that is freely rotatable through a guide pin provided at one end of a dedicated table, and By locking the free end of the record cleaner main body with a locking frame provided at the end, the rotary drive plate is rotated, the record is rotated, and the rotary brush cleans the record. This allows for uniform cleaning of record discs without damaging the label surface of the disc.

Hereinafter, the present invention will be explained based on drawings showing one embodiment thereof. Fig. 1 shows the dedicated table and the record cleaner body separated, and 1 is the dedicated table, and one end of this dedicated table 1 is provided with a guide pin 2 into which the center hole of the record disc, which will be described later, is fitted. , and a rotatable rotary plate 3 is provided around the guide pin 2. Further, the other end of the dedicated table 1 is provided with a locking frame 4 and a rotatable roller 5. 6 is a record cleaner body, and this record cleaner body 6 has a rotary drive plate 7.
, a switch button 8 and a dust cover 9 are provided.

Figure 2 shows a record 1° placed on a special table 1.
The figure also shows a state in which the free end of the record cleaner main body 6 is locked to the locking frame 4 of the dedicated table 1.

Figure 3 shows the record cleaner body 6 and dedicated table 1.
11 is a motor installed in the record cleaner main body 6, and a pulley 13 is attached to a motor shaft 12 protruding from one end of the motor 11. Reference numeral 14 denotes a rotating shaft located below the motor 11 and rotatably supported by a support frame 16 within the record cleaner main body 6. A pulley 16 is attached to one end of this rotating shaft 14.
A belt 17 is stretched between this pulley 16 and the pulley 13 of the motor 11. Reference numeral 18 denotes a rotary brush rotatably provided within the record cleaner main body 6, and one end shaft portion 19 of this rotary brush 18 is connected to a brush bearing 20 VC.
! The rotating brush 18 is rotatably supported, and the other end shaft portion 21 of the rotating brush 18 is connected to the other end of the rotating shaft 14 via a connector 22.

A battery 23 is located above the rotating brush 18 and housed in the record cleaner main body 6. Further, the rotary plate 3 provided at one end of the dedicated table 1 is rotatably supported by a plurality of poles 24. Pads 25 and 26 are provided on the surfaces of the rotary drive plate 7 and the rotary plate 3 that are in contact with the record 10, and the pads 25 and 26 are made of a material with high frictional resistance such as rubber.

FIG. 4 shows the structure for transmitting power to the rotary drive plate 7. Reference numerals 27a, 27b, and 27c are a reduction gear group consisting of one pulley and a plurality of gears, and this reduction gear group 27a
, 27b, 27c, %1 goo! 7-27a
are a pulley 28 and a belt 29 provided at one end of the rotating shaft 14.
The final stage gear 27c meshes with an internal gear 3o provided on the inner periphery of the rotary drive plate 7. As shown in FIG. 4 and FIG.
has been established.

FIG. 5 shows a record disc in one embodiment of the present invention.

Fig. 3 shows a side sectional view of the cleaning device.

In the above configuration, the record disc 1.0 (7) cleaning operation will be explained. First, the center hole 1oa of the record 1o is fitted into the guide pin 2 of the dedicated table 1, and the record 1o is placed on the dedicated table 1. After that, the record cleaner body 6 is positioned above the record disc 10.
In this case, the record cleaner main body 6 is fitted with the guide pin 2 through the hole 31 of the rotary drive plate 7, and the free end of the record cleaner main body 6 is locked into the locking frame 4 of the dedicated table 1. and set it. In this state,
When the switch button 8 is pressed, the motor 11 is energized, and the power of the motor 11 is transferred to the Boo+J-13° belt 17. Pulley 162 is transmitted to the rotating brush 18 via the rotating shaft 14, and the pulley 2 provided at one end of the rotating shaft 14
Belt 29 from 8. Pulley 27a, reduction gear group 27b
, 27c and the internal gear 3o.

Then, the record disc 1° rotates around the guide pin 2 by rotating the rotary drive plate 70 times. As the record disc 1o rotates, dust accumulated in the sound grooves of the record disc 10 is stirred up by the rotation of the rotating brush 18 and sucked into the dust case.

Thereby, cleaning of the record disc 10 is automatically performed. In addition, the amount of contact between the bristles of the rotating brush 18 and the sound groove of the record 10 during this cleaning is 0.5
The thickness can be maintained within an appropriate range of 11 to 1.0 inches. In addition, when the amount of contact becomes 1, Ovrvi or more, the current consumption increases rapidly, and when the amount of contact becomes less than 0.511,
Cleaning performance deteriorates rapidly.

As described above, according to the present invention, a record is positioned between a rotary plate that is freely rotatable through a guide pin provided at one end of the dedicated table and a rotary drive plate of the record cleaner main body, and the record is placed in a position other than the dedicated table. 1 with the locking frame provided at the end
/:IT)" The free end of the main body is locked, and the record is rotated by the rotation of the rotary drive plate, and the record is cleaned with a rotating brush. Since the periphery of the record is pressed against the dedicated table and the ends of the record cleaner body, the warp of the record is corrected and the record is kept flat, resulting in uniform leaning and the record cleaning. Since the cleaner body is stationary and the record disc rotates to perform cleaning/guwing, the conventional record cleaner body does not scratch the label surface of the record like a self-propelled cleaner. It will also disappear.
