Description

[Detailed Description of the Invention] This invention relates to a self-propelled record cleaner that collects dust on a record while self-propelled and turns in the circumferential direction on the record.

Conventionally, when cleaning a record, the record was held while being held with one hand, which resulted in the risk of staining the record or accidentally dropping the record and damaging it. In addition, since cleaning was performed while changing the gripping position of the record during cleaning, uneven cleaning was likely to occur.

Therefore, one end of the cleaner body is rotatably attached to a spindle of a turntable, etc., and the cleaner is run over the record centering around the spindle.
A self-propelled record cleaner is provided that collects dust adhering to a record using a roll brush supported on the cleaner body.

However, in the above-mentioned record cleaner, the drive wheel, which is the means for rotating the cleaner body above the record, runs on the label part of the record.
Dirt from carbon black, vulcanizing agents, etc. added to the drive wheels adheres to the label part while it is rolling, spoiling the aesthetic appearance of the record, making it difficult to read the characters written on it, and causing damage to the label part. Since the surface finish differs depending on the record, if the label part has a glossy finish, the drive wheel may slip and the cleaner body may not run or rotate. In addition, if the record is deformed or warped due to temperature changes or other external forces, the cleaner itself cannot correct the warp by itself, and if you continue cleaning, the tip of the roll brush will be on the disc surface. There were parts that did not come into contact with each other, and as a result, dust adhering to those parts could not be collected, significantly impairing the cleaning effect.

In view of the above drawbacks, this idea includes a stabilizer placed on the label section _R1 of the record R,
A cleaner body that rotates around this stabilizer, a drive wheel that contacts and rolls on the stabilizer, a roll brush that removes dust attached to a record, and a drive wheel and roll brush that are attached to the cleaner body. The stabilizer is equipped with a drive mechanism for rotation, and a dry battery that serves as a power source for the drive mechanism is built into the stabilizer, and the drive mechanism side and the dry battery side are electrically connected when the cleaner body is attached to the stabilizer. By providing a self-propelled record cleaner, it is an object of the present invention to eliminate the above-mentioned drawbacks, reduce the size and weight of the cleaner body, facilitate battery replacement, and improve operability.

Hereinafter, embodiments of this invention will be described based on the drawings.

In FIGS. 1, 2, and 3, 1 is a synthetic resin cleaner body, T is a turntable of a player, R is a record set on the turntable T, and S is a spindle of the turntable T.

Reference numeral 51 denotes a disc-shaped stabilizer that is placed on the label part R ₁ of the record R and applies an appropriate load to the record R. The stabilizer 51 can be divided into a main body case 52 and an upper lid part 53, and is attached to the top surface of the upper lid part 53. A spindle portion 54 is provided protruding from the center. The stabilizer 51 is configured to be separable from the cleaner main body 1, and the stabilizer alone is made of a weight body suitable for correcting warping and distortion of the record R.

The base 1a and the tip 1b of the cleaner main body 1 are formed at different levels, and the inside thereof is divided by a partition wall 2 into a drive chamber 3 on the base 1a side and a brush storage chamber 4 on the tip 1b side. has been done. A shaft hole 7 is bored in the lower surface of the base portion 1a of the cleaner body 1, and the shaft hole 7 is pivotally connected to the upper surface spindle portion 54 of the stabilizer 51.
4, and when the cleaner body 1 is set on the stabilizer 51 placed on the label part _R1 of the record R, the lower surface of the base 1a of the cleaner body 1 is connected to the upper surface 55 of the stabilizer 51, and the tip The lower surface of 1b corresponds to the sound part _R2 of the record R, respectively.

A motor 5 is housed in the drive chamber 3 of the cleaner main body 1, and the rotational force of the output shaft 6 of the motor 5 is transmitted to the drive wheels 10 via a reduction gear system 9.
This driving wheel 10 is set to have a rotational speed of 200 to 300 R, P, M, and a part of its outer periphery protrudes outward from the lower surface of the cleaner base 1a and rolls on the upper surface 55 of the stabilizer 51. It is arranged so that

Reference numeral 11 denotes a roll brush supported in the brush storage chamber 4, which is driven by the motor 5 at 2500 to 3000R.
They are given rotational speeds of approximately P and M, and are connected to rotate in the opposite direction to the drive wheels 10. The dust on the record R that has been scraped up by the roll brush 11 is introduced into the dust collection chamber 12 on the airflow generated by the high speed rotation of the brush, and the dust collection chamber 12 is removably covered. Only dust is collected by the filter section 13. 14 is a start/stop switch.

Here, a dry battery 8 that serves as a power source for the built-in motor 5 is housed on the stabilizer side. To describe a specific example, as shown in FIGS. 2 and 5, a predetermined dry battery 8 is housed in a battery housing part 56 formed on the main body case 52 side of the stabilizer 51, and the top cover part 53 is screwed from above. If so, wear business clothes. Here, a conductive member 5 is provided on the rolling surface of the driving wheel 10 of the cleaner on the upper surface 55 of the upper lid portion 53 over the entire circumference.
7, and the spindle part 54 protruding from the center of the upper cover part 53 is also formed of a conductive material. With the upper cover part 53 screwed onto the main body case 52, the conductive member 57 is connected to one side of the dry battery 8. The other electrode is connected to the spindle portion 54.

Further, on the cleaner body 1 side, a conductive plate 15 is disposed on the inner wall of the shaft hole 7 bored in the lower surface thereof, and the outer periphery 10a of the drive wheel 10 is made of metal or a conductive member is attached. The drive chamber 3 is formed with a contact brush 16 that is always in contact with a part of the drive wheel outer periphery 10a. and is connected to the motor 5.

Therefore, if the shaft hole 7 of the cleaner body 1 is pivotally connected to the spindle portion 54 of the stabilizer 51 and the cleaner body 1 is set on the stabilizer 51,
No matter what position the cleaner body 1 rotates around the spindle part 54, the conductive member 57 always rotates with the outer periphery 10a of the drive wheel 10 and the spindle part 54 with the conductive plate 15.
Stabilizer 5 via these and switch 14
Electric power from a dry battery 8 housed in the motor 5 is supplied to the motor 5 .

Next, an example of how to use the above record cleaner is as follows.
As shown in FIGS. 2, 3, and 4, a stabilizer that also serves as a battery case is placed on the label portion R ₁ of the record R, and the cleaner body 1 is mounted on the spindle portion 54 provided upright on the stabilizer 51. Shaft hole 7
After fitting and setting the cleaner body 1,
When the switch 14 is turned on and the motor 5 is started, the roll brush 11 moves to the sound part of the record R.
_R2 , for example, in the direction of arrow a, and at the same time the drive wheel 10 rotates on a conductive member 57 formed on the stabilizer 51 in the opposite direction, in the direction of arrow b, the cleaner main body 1 is rotated around the spindle part to record the record. Travels on R in circumferential direction C. Along with this running, the roll brush 11 rotates in the opposite direction to scrape up the dust on the record R and automatically collect it in the dust collection chamber 12.

In another embodiment, the contact brush 16 provided in the cleaner body 1 and the conductive plate 15 on the inner wall of the shaft hole 7 are connected directly to the motor 5 without going through the switch 14, and the cleaner body 1 is simply set on the stabilizer 51. Then, power from the dry cell battery 8 housed in the stabilizer 51 may be supplied to the motor 5, and the motor 5 may start to start.

As described above, according to the present invention, when cleaning a record disc, the drive wheel 10 contacts the stabilizer 51 and rolls, so that the label part of the record disc R is not removed as in the conventional case.
This prevents the inconvenience of getting dirt or scratches on R ₁ , and also prevents the stabilizer 5 from getting dirty or being scratched.
1 and the own weight of the cleaner body 1, it is possible to clean the record R while correcting the warping and distortion caused by the roll brush 11, so that the roll brush 11 is always in even contact with the sound part R ₂ of the record. Since the machine rotates around the entire circumference of the sounding part while doing so, there is no dust left uncollected, making it possible to clean very efficiently. Moreover, since the dry battery 8 serving as a power source is housed in the stabilizer 51 in a freely insertable and removable manner, the cleaner body 1 can be made smaller and lighter, and the dry battery can be easily replaced, thereby improving operability. It is possible to provide a record cleaner according to the purpose.

Furthermore, when playing, by removing only the cleaner body, the weight of the stabilizer allows the record to be played in a state in which warping and distortion are corrected, so that normal reproduced sound can be obtained.
