Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a device for removing dirt and dust (hereinafter referred to as dust, etc.) adhering to records, etc., and is particularly suitable for removing dust, etc. , relates to a base on which an object to be wiped is placed.

[Prior Art] In recent years, large quantities of records, compact disks, etc. have been used not only in general households but also in the rental industry, second-hand record industry, and the like. Also, CDs are used in the computer-related industry.
(compact disk), VD (video disk),
LDs (laser disks) etc. came into use. However, dust and the like tend to adhere to these recorded materials, and these dust and the like cause noise when the recording is reproduced.

Therefore, the conventional methods for removing such dust include wiping with a velvet wiper, removing the adhesion of dust using adhesive tape, and removing static electricity from PVC (polyvinyl chloride) boards using antistatic liquid. There are methods to prevent dust and remove dirt, oil, etc. from the surface using a cleaning solution. In all of these methods, the object to be wiped is held with one hand and the wiping operation is performed.

[Problem that the invention aims to solve] However, most of the dust that adheres to PVC panels is fine dirt and hand marks (oil and fat), and once these dust adheres, it cannot be removed simply by wiping with a velvet wiper etc. It is extremely difficult to do so. Therefore, if you apply spray-type record cleaning liquid etc. without removing the dust,
The adhesion of record cleaning liquid to dust particles can also cause more noise than before. Furthermore, fine dust that has entered the sound groove is thoroughly rubbed with a fine-fiber velvet wiper to generate fine dust and wiped away, but due to the static electricity generated by rubbing, new dust particles may adhere to the back side. The drawback was that it caused noise.

Therefore, the inventors of the present invention conducted extensive studies to solve the above problem, and found that when a record is placed on an electret sheet, new dust particles will adhere to the back surface even if the record is wiped with a wiper. We discovered that this is not the case and arrived at this invention.

Therefore, an object of the present invention is to provide a cleaner base that can efficiently remove dirt adhering to records and the like.

[Means for solving the problem] The above-mentioned object of the present invention is to provide a base for a cleaner characterized by stacking electret sheets on a base for placing an object to be wiped. achieved.

Here, the electret sheet is a sheet-like material that permanently maintains electric polarization even in the absence of an external electric field and forms an electric field with respect to the surroundings.

Examples of the electret sheet include highly oriented and polarized "electret nonwoven fabric" developed by Toray Industries, Inc.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a base on which the object to be wiped is placed when removing dirt from the object. In terms of operation, it is preferable that a center spindle 2 is provided in the center of the base, and that a hole bored in the center of the object to be wiped is fitted into the center spindle 2. Further, in order to facilitate the wiping operation, it is preferable to lower the upper surface of the base except for the part where the object to be wiped is placed and provide a step, and to install a sheet presser 3 for pressing the electret sheet. The base at the bottom of the electret sheet may be cut into removable rings so that the size of the base can be changed according to the size of records, etc. The base can be made of any material such as plastic, metal, wood, paper, etc., but if it is made of a conductive material, it is desirable to attach an electrically insulating material such as a rubber pushpiece 4 to the bottom of the base.

Reference numeral 5 indicates an electret sheet superimposed on the base. Known materials can be used for the electric sheet.

[Function] With the above configuration, when the object to be wiped is placed on the base on which the electret sheets are stacked and the dirt adhering to the object to be wiped is wiped by the wiper, the object to be wiped is placed on the base on which the electret sheets are stacked, and when the wiper wipes away the dirt attached to the object to be wiped, the object to be wiped is Due to the electret effect, the electret sheet not only does not move even when wiped with sufficient force with the wiper and has good workability, but also prevents dust from adhering to the back side of the object being wiped due to static electricity generated during wiping. This can be prevented by the electric field effect.

A wiper 8 covered with velvet fiber is used to wipe off PVC records, etc.
When cleaning VD, etc., attach the adapter 7 to the center spindle, and use a wiping cloth made of ultrafine fibers with a fiber diameter of 1 denyl or less (for example, Teijin Ltd. product name: Microstar,
A wiper 9 or the like equipped with a wiper (manufactured by Kanebo Co., Ltd. under the trade name Sabina Mini Maxx, manufactured by Toray Industries, Inc. under the trade name Miraclestion, etc.) may be used. This is PVC
This is because unlike discs, CDs, VDs, etc. do not have sound grooves and have a mirror surface.

[Effects of the invention] As detailed above, according to the invention, it is possible to prevent the harmful effects caused by wiping the object with sufficient force, so that it is possible to remove fine dust that could not be removed conventionally. becomes possible. This reduces unpleasant crackling noises and noises caused by oil stains when playing records, and also dramatically reduces dirt and dust adhering to the stylus, increasing stylus trackability and improving sound quality. This is a significant improvement and at the same time can extend the life of expensive styli.
