Description

[Detailed description of the invention] This invention relates to a record cleaner. More specifically, this invention relates to a record cleaner that can reliably remove small dust particles adhering to a record disc through a simple operation without applying direct force to the record disc.

Conventionally, light and small dust particles adhering to records are removed from the record by moving a piece of very soft cloth such as velvet along the grooves of the record and collecting it around the record. It had been. However, with this removal method, it is necessary to move a piece of cloth such as velvet by directly contacting the record with a certain pressing force, so if the pressing force is too strong, it will easily damage the record, and if the pressing force is too small, it will easily damage the record. If it is too long, the removal of dust etc. from the record becomes insufficient, and there is a drawback that sufficient skill is required to completely remove the dust etc. collected in the peripheral area from the record surface.

This idea was made in view of the above circumstances, and by generating static electricity on a synthetic resin sheet facing the record surface, small dust particles that adhere to the record can be removed without applying direct force to the record. To provide a record cleaner capable of adsorbing and removing.

This invention will be explained in detail below based on the embodiments shown in the figures. Note that this invention is not limited to this.

Figures 1 to 3 show an embodiment of this invention, in which a cleaner body 1 is constructed such that a rectangular synthetic resin sheet 2 can be bent in the same direction on both sides of a central portion m by a certain length h. ing. As the synthetic resin sheet 2, for example, a transparent polystyrene sheet or a laminated sheet formed by adhering polystyrene films to both sides of a polystyrene foam may be used. When the bending slope 1 is bent in the same direction, either one of the first substrate 3 and the second substrate 4 facing each other, for example, the inner side of the first substrate 3 has a surface from the central portion m. LP with record distance
A space piece 5 made of the same material as the synthetic resin sheet 2 is fixed at a position slightly larger than the diameter of the board. The height n of the spacer piece 5 is the central portion m
The constant length h is set to be approximately the same as the constant length h.

The first substrate 3 closer to the center part m than the spacer piece 5
A disk-shaped record holding member 6 made of a resilient synthetic resin foam such as urethane foam is fixedly installed in the center of the record holding member 6 . Reference numeral 7 denotes another record holding member fixed in exactly the same manner at a corresponding position on the second substrate 4, and these record holding members 6 and 7 are designed to prevent the record from coming into contact with the inner surfaces of the substrates 3 and 4. In addition to the height dimension necessary for holding between the substrates 3 and 4, a circular hole 8 is provided in the center of the opposing surfaces of the record holding members 6 and 7 to be used for alignment with the record. , 8 are formed. At the corresponding positions of the first and second substrates 3 and 4 outward from the spacer piece 5, there is a cleaner body 1.
Openings 9, 9 are provided for convenient holding.

FIG. 3 shows a flat synthetic resin case 10 that slidably houses the cleaner body 1.
This case 10 has the first and second parts of the cleaner main body 1.
each inner surface 12 facing the outer surface of the substrates 3, 4;
An electrical conductor 11 having a different electrification series from the synthetic resin material of the cleaner body 1, such as fur, flannel, silk, rubber, etc., is fixed to 13.

Next, the effects of the record cleaner having the above configuration will be explained.

A record R from which dust is to be removed is placed on one of the record holding members 6 and 7 of the opened cleaner main body 1, for example, on the upper surface of the record holding member 6, as shown in FIG. At this time, by aligning the hole provided in the center of the record R with the circular hole 8 of the record holding member 6, the record R is placed in the center of the record holding member 6. Next, when the second substrate 4 is bent as shown by the arrow P in FIG.
The second substrate 4 is held elastically by the first substrate 4.
The first substrate 3 is maintained at a predetermined distance by a spacer piece 5 fixed to the first substrate 3.

In this state, when the outer surface of the second substrate 4 is rubbed with a poor conductor of electricity, such as fur, which has a different electrification series from that of the synthetic resin sheet 2, the synthetic resin substrates 3 and 4 charged by the friction will become To surely and efficiently adsorb light and small dust particles adhering to a record disc R to the inner surface of a substrate by the action of static electricity and remove them. Moreover, in this embodiment, since the record R is held by the record holding member 6 provided at the center of the first and second substrates 3 and 4, the size of the record R does not depend on the size of the record R. It is possible to remove dust adhering to the record R without any problem.

At this time, if the synthetic resin sheet 2 is made of a transparent material, there is an advantage that the state of adsorption of dust to the inner surfaces of the substrates 3 and 4 can be accurately grasped. Also, if you use a material with non-foamed films laminated on both sides of the foam,
It has the advantage of being lightweight and durable.

The synthetic resin sheet 2 may be rubbed by a poor electric conductor 11 such as fur by holding it directly in your hand, but it is possible to rub the synthetic resin sheet 2 by holding it directly in your hand. Insert the cleaner main body 1, hold the openings 9, 9 in your hand, and move it back and forth in the left and right directions as shown by the arrows to connect the first and second Both outer surfaces of the two substrates 3 and 4 may be rubbed simultaneously. If there is no defective electrical conductor 11 such as fur or the case 10, dust can be removed by directly rubbing the outer surface of the cleaner body 1 with the palm of the hand.

The record cleaner of this invention can also be used as a simple and attractive bag for carrying records by inserting it so that the openings 9, 9 of the cleaner body 1 come out from one end of the case 10. Become.

FIG. 4 shows another embodiment of this invention (the same components as in FIG. 1 are indicated by the same reference numerals with the addition of "a"), which shows a disc-shaped record holding member of the first embodiment. In place of 6 and 7, first and second substrates 3a,
Rectangular parallelepiped record holding members 14 are fixed at corresponding positions around the periphery of the record holding member 4a. In this case, it is desirable that the record holding member 14 be provided at a position corresponding to the peripheral part of the record R.
When the record holding member 14 covers the groove portion of the record R, it is preferable that each length of the record holding member 14 is short only in the central portion.

When the record holding member 14 is configured in this way, it holds the peripheral part of the record R, so even when the record R is large like an LP size, dust can be removed in a stable holding state. It is convenient to use as a dedicated record cleaner for each size of LP, EP, etc.

In the above embodiment, if the disk-shaped record holding members 6 and 7 shown in the first embodiment are installed together as shown by the two-dot chain line, dust can be kept in a stable state regardless of the size of the record R. can be removed.

As is clear from the above explanation, the record cleaner of this invention generates static electricity on the first and second substrates held at an appropriate distance from the record to remove dust attached to the record. Because it removes light and small dust particles, it is possible for anyone to remove light and small dust particles reliably and efficiently using simple operations without applying any direct force to the record disc. can.
