JPS63298762A - Cleaner for disk carrier roller - Google Patents

Abstract

PURPOSE:To attain simple and sure cleaning to the surface of a loading roller by providing a sending kill means having a shape corresponding to the shape of the loading roller and not functioning a disk sensing pin of a player to its tip. CONSTITUTION:A flange 23 being of the shape and size able to be interposed between loading rollers 11 and 12 and having a wider width than that of a loading throat 2 of a player 1 is provided to one end and a cleaning tongue 20 is formed, which is provided with a sensing function kill (recessed part) 21A to be escaped from a disk sensing mechanism 3 of the player 1 at the tip 21. Then the loading rollers 11, 12 are cleaned by loading the cleaning tongue 20. Thus, a foreign or dust adhered to the loading rollers is removed by a simple operation.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a cleaner for disk transport rollers, and more particularly to a cleaning device suitable for a loading device equipped with a pair of loading rollers. rPrior Art A disc player, typically a CD player, is equipped with a loading device that automatically loads discs.
In this loading device, a pair of loading rollers sandwich a disk and the loading rollers are driven and rotated to load the disk into a player.

[Problems to be solved by the invention]

The above-mentioned loading device for a disc player uses a pair of loading rollers to sandwich and feed the disc with a constant pressure, so if there is hard dust on the loading roller, it may cause the disc to be pressed against the disc during loading. There was a problem that it would leave marks. Particularly, in in-vehicle CD players, etc., not only dirt and dust but also foreign matter from the outside often adhere to the loading roller, which may cause the disc to drop out.

[Means to solve the problem]

Therefore, this invention aims to make it possible to remove foreign matter and dust attached to the loading rollers of a disc player, as well as static electricity, with a simple operation. A cleaning tongue is formed at one end with a flange wider than the player's loading throat, and the tip has a detection function killer to avoid the player's disc detection mechanism. □It is characterized by leaning.

【Example】

Hereinafter, in Figure 0, an embodiment of the present invention will be explained along with the accompanying drawings, reference numeral 11.12 indicates a pair of loading rollers, both of which have a minimum diameter at the center and a diameter at both ends. It has a laterally symmetrical tapered shape with a maximum diameter, and has a disk feeding function, and is provided inside the disk loading throat 2 of the disk player 1. A cleaning tongue 20 that can pass between the loading rollers 11.12 is prepared, and the tip 21 of this cleaning tongue 20 is semicircular.
It has a rectangular main body portion 22 with a width slightly smaller than the full width of the disc loading throat 2, and a flange 23 larger than the width of the disc loading throat 2 at the end of the main body portion 22. The main body 22 of the cleaning tongue 20 has a sloped surface 22A that is thick at the center and gradually decreases in thickness toward both flanges, and this sloped surface 22A corresponds to the taper of the loading rollers 11 and 12. It has a shape that allows it to be inserted between both rollers. Furthermore, the tip 21 of the cleaning tongue 20 has a recess 21 that avoids the disc detection bin 3 provided in the player 1.
^ is provided to prevent the disc detection bin 3 from performing the same operation as loading the disc, and unless the disc comes into contact with this disc detection bin 3, the clamper 4 of the clamp arm 4A will not operate. The loading rollers 11 and 12 continue to rotate while slipping on the surface of the cleaning tongue 20 due to the loading action. At least the surface of the cleaning tongue 20 is made of an elastic and soft material such as cloth or foam, and can be impregnated with a cleaning liquid. When the cleaning tongue 20 is to be removed, an ejecting action is performed, or a microcomputer-controlled mechanism is provided in the player 1 itself to automatically eject it after a few seconds. Therefore, when cleaning the loading roller 11.12, simply insert the cleaning tongue 20 into the disc loading throat 2, and the loading roller 11.12 of the player 1, which has the function of automatically loading the disc, will clean the cleaning tongue 20. Loading is applied in the same way as disc loading. At this time, since the cleaning tongue 20 has a recess 21^ that prevents it from coming into contact with the disk detection bin 3, the loading rollers 11, 12 rotate while slipping on the surface of the cleaning tongue 20, and foreign matter on the surface or , dust is removed. Further, by forming the loading rollers 11 and 12 from a conductive material, static electricity can be removed from the surfaces of the loading rollers 11 and 12. Note that the above is a type in which the disc comes into contact with a detection bin in order to detect the loading state of the disc, but in the case of a player that uses a photo sensor, the position corresponding to the photo sensor should be made transparent or transparent. Making holes is done. Furthermore, if the loading roller is straight, the sloped surface of the main body is not necessary.

【Effect of the invention】

As is clear from the above description, the disc pickup/feed roller cleaner of the present invention has a shape that corresponds to the shape of the loading roller, and has a detection killer that disables the disc detection pin of the player at the tip. Since the means is provided, the surface of the loading roller can be easily and reliably cleaned by simply loading the cleaning tongue in the same way as when loading a disk, and it is possible to prevent marks from being made on the disk.
