Description

[Detailed Description of the Invention] This invention relates to a self-propelled record cleaner that travels and rotates on a record while collecting dust on the record by rotating a roll brush.

Conventionally, when cleaning a record, the user had to hold the record with one hand, which could leave marks on the record or cause the record to be accidentally dropped and damaged. In addition, since cleaning was performed while changing the gripping position of the record during the cleaning process, 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 had a glossy finish, the drive wheel would slip and the cleaner itself would not run or rotate. In addition, if the record is deformed or warped due to temperature changes or other external forces, the warp cannot be corrected by the cleaner's own weight alone, and if you continue cleaning, the tip of the roll brush will come into contact with it. There is a part that does not occur, and this is because
Dust adhering to that area 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. By providing a self-propelled record cleaner equipped with a drive mechanism for rotation, the above-mentioned drawbacks are solved and the performance of the record cleaner is improved.

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

In Figures 1, 2, and 3, 1 is the cleaner body made of synthetic resin, T is the turntable of the player, R is the record set on the turntable T, and S is the spindle of the turntable T. It is. Reference numeral 51 denotes a disk-shaped stabilizer which is placed on the label portion _R1 of the record R and presses down the record R. A spindle portion 53 is protruded from the center of the upper surface 52 of the stabilizer. The stabilizer 51 is configured to be separable from the cleaner main body 1, and the stabilizer 51 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, which is pivotally attached to the spindle portion 53 of the stabilizer 51, is bored in the lower surface of the base portion 1a of the cleaner main body 1, and the cleaner is set when the shaft hole 7 is pivotally attached to the spindle portion 53. The bottom surface of the base 1a of the cleaner body 1 is the top surface 52 of the stabilizer 51, and the bottom surface of the tip 1b is the sound part of the record R.
Each corresponds to R ₂ .

A motor 5 is housed in the drive chamber 3 of the cleaner body 1, and the rotational force of the motor output shaft 6, which rotates using a built-in dry cell battery 8 as a power source, is transmitted to the drive wheels 10 via a reduction gear system 9. The drive wheel 10 is set to have a rotational speed of 200 to 300 R.PM, and is arranged so that its outer periphery protrudes from the lower surface of the cleaner base 1a and rolls on the upper surface 52 of the stabilizer 51.

Reference numeral 11 denotes a roll brush supported in the brush storage chamber 4, which is heated at 2500 to 3000 R.PM by the motor 5.
The drive wheel 10 is connected to rotate in the opposite direction to the drive wheel 10. The dust on the record R that has been scraped up by the roll brush 11 is introduced into the dust collecting chamber 12 by the air flow generated by the high speed rotation of the brush, and the filter section 13 removes only the dust. The dust is stored in the dust collection chamber 12. 14 is a start/stop switch, and 15 is an openable/closeable lid for replacing the dry battery 8.

Here, the weight of the stabilizer 51 is 500~
About 1000g, and the top surface of the stabilizer 5
2 is provided with an anti-slip knurl 54 at the drive wheel running position to prevent the drive wheel 10 from slipping.
Efforts have been made to increase the coefficient of friction between the drive wheel 10 by providing a rough surface or by providing a rough surface. The anti-slip knurl 54 may also serve as a stroboscope for measuring the number of rotations of the turntable T of the player.

In the above configuration, FIGS. 2, 3, and 4
In the figure, the stabilizer 51 is placed on the label part R ₁ of the record R set on the turntable T of the player, and the shaft hole 7 of the cleaner body 1 is inserted into the spindle part 53 erected on the upper surface 52 of the stabilizer 51. After fitting and setting the cleaner body 1, turn on the switch 14 to turn on the motor 5.
When activated, the roll brush 11 rotates on the sound part _R2 of the record R, for example, in the direction of arrow a, and at the same time, the drive wheel 10 rotates on the upper surface 52 of the stabilizer 51 in the opposite direction, in the direction of arrow b. , the cleaner body runs on the record R in the circumferential direction C with the spindle portion 53 as the center. 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 the above embodiment, the drive wheels 10 are arranged so as to roll on the upper surface 52 of the stabilizer 51, but they may also be arranged to roll on the circumferential surface of the stabilizer 51. The spindle part 53 may be detachable, and the center of rotation of the cleaner body 1 is set at the center of the stabilizer 51 as a concave part.
A convex portion that fits into the concave portion may be formed on the lower surface of the convex portion, and the convex portion may be rotated around this convex portion.

Here, since the drive wheel 10 contacts and rolls against the stabilizer 51, the label portion of the record R
It is possible to prevent the inconvenience of dirt adhering to R ₁ , and to ensure stable running regardless of the surface finish of the label portion R ₁ .
Since the cleaning can be performed while correcting the warpage that has occurred on the record R due to its own weight, the outer periphery of the roll brush 11 is always in constant contact with the surface of the record R, completely removing dust attached to the record. The cleaning effect can be improved.

By the way, by removing only the main body of the cleaner when playing, the weight of the stabilizer allows the record to be played with warpage and distortion corrected, so that normal reproduced sound can be obtained.
