Abstract

PURPOSE:To execute simultaneously uniform cleaning and elimination of charging by cleaning a record disk with a rotary brush and also neutralizing and eliminating an electrostatically charged object of the record disk by corona discharge from a discharge terminal of an electrostatic eliminator. CONSTITUTION:As a record disk 8 rotates, dust which collects in a sound groove of the record disk 8 is scraped up by a rotation of a rotary brush 16, and is absorbed into a dust case. Accordingly, a cleaning work of the record disk 8 is executed automatically. Also, an earth plate 51 is provided in a cover 50 for protecting a discharge terminal 30 of an electrostatic eliminator 29, and this earth plate 51 serves for generating a strong electric field area on the lower face of the record disk 8. Accordingly, in this state, when power supply voltage supplied to the electrostatic eliminator 29 is boosted by a boosting transformer, and its high voltage is impressed to a discharge terminal 30, the discharge terminal 30 starts corona discharge, ionizes air, and draws a different polarity molecule in a weak electric field area of the upper face of the record disk 8 and neutralizes it.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a record cleaning device capable of simultaneously cleaning a record and neutralizing and removing charged objects on the record.

Structure of conventional examples and their problems Some conventional record cleaning devices clean the record by keeping the record in a stationary state and rotating a record cleaner body having a rotating brush. However, in this case,
It has the disadvantage that the amount of contact between the bristles of the rotating brush and the sound groove of the record is unstable with respect to the edge of the record, and as a result, the cleaning performance varies significantly depending on the record. Since the record cleaner itself runs on top of the record, there is also the problem that the label surface of the record is scratched.

Furthermore, in the past, when neutralizing and removing charged objects from records, a separate static eliminator was used and the process was carried out separately from the record cleaning process.
This requires a lot of effort and is very inconvenient for users.

Purpose of the Invention In view of the above-mentioned conventional problems, the present invention is capable of uniformly cleaning a record disc without damaging the label surface of the record disc, and also removes the charge from a charged object on the record disc by cleaning the record disc. The object of the present invention is to provide an easy-to-use record cleaning device that can be used at the same time as cleaning work.

Structure of the Invention In order to achieve the above-mentioned object, the present invention positions a record disc between a rotary plate that is freely rotatable through a guide bin provided at one end of a dedicated table and a rotary drive plate of a record cleaner main body, and The free end of the record cleaner body is locked with a locking frame provided at the other end of the dedicated table, and as the rotary drive plate rotates, the record is rotated (1) and the rotating brush is used to clean the record. At the same time, the charged object on the record is neutralized and removed by corona discharge from the discharge terminal of the static eliminator provided on the dedicated table. According to this configuration, the periphery of the record is Since the edges of the table and record cleaner body are pressed against each other, the warp of the record is corrected and kept flat, resulting in uniform leaning and the record cleaner body being stationary. Since the cleaner cleans the record by rotating the record, it eliminates the possibility of scratching the label surface of the record, which is the case with conventional record cleaners that run on their own. Since the removal of the charged object can be carried out at the same time as cleaning the record, it is very easy to use.

It is also supplied to the static eliminator 29. In this case, since the static eliminator 29 is located below the record 8 and protrudes beyond the dedicated table 1, the user is prevented from touching the discharge terminal 30 of the static eliminator 29 and getting an electric shock. It is something that can be prevented. The motor 9 is rotated by the supply of power, and the power is supplied from the motor boot 9-11, the belt 15,

As the record 8 rotates, the dust accumulated in the sound groove of the record 8 is scraped up by the rotation of the rotating brush 16 and sucked into the dust case.
The cleaning work is done automatically.

Further, the removal of the charged object from the record disc 8 by the static eliminator 29 is performed in the following manner. That is, as shown in FIG. 8, a grounding plate 61 is provided inside the cover 6Q that protects the discharge terminal 30 of the static eliminator 29. It plays the role of creating an area. Therefore, in this state, when the power supply voltage supplied to the static eliminator 29 is boosted by the step-up transformer 43 shown in FIG. 6 and the high voltage is applied to the discharge terminal 30, the discharge terminal 3o starts corona discharge. This ionizes the air and attracts and neutralizes molecules of different polarity in the weak electric field region on the upper surface of the record 8, so that the charged object on the upper surface of the record 8 is neutralized and removed.

Effects of the Invention As described above, according to the present invention, a record disc is positioned between a rotary plate that is freely rotatable through a guide bin provided at one end of a dedicated table and a rotary drive plate of a record cleaner main body, and The free end of the record cleaner main body is locked by a locking frame provided at the other end of the dedicated table, and the record is rotated by the rotation of the rotary drive plate, so that the rotating brush cleans the record. Because of this, the periphery of the record is pressed into contact with the dedicated table and the ends of the record cleaner body, so the warp of the record is corrected and the record is kept flat, resulting in uniform leaning. In addition, since the record cleaner itself is stationary and the record rotates, there is no chance of scratches on the label surface of the record unlike with conventional record cleaners that move on their own. Moreover, since the charged object on the record can be removed at the same time as the cleaning of the record, it is very easy to use, and has various excellent effects.
