Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for recording and reproducing information on a card-shaped information recording medium, and particularly to dust, dust, fingerprints, and oils attached to the information recording medium. The present invention relates to a removal recording / reproducing apparatus having a cleaning function for removing a recording medium.

[Conventional technology]

Conventionally, as a means for cleaning dust, dust, fingerprints, oil, etc. attached to an information recording medium used in a card-shaped information recording / reproducing apparatus, for example, as shown in FIG.
A cylindrical cleaning roller as described in JP 7487
19 removes oil, fingerprints, relatively small dust, etc. attached to the recording surface by rotating as the recording medium 20 moves, and incorporates a conductive brush 21 into the information recording medium transport path. It has been proposed to remove relatively large dust attached to the recording medium. These cleaning operations are performed both when the recording medium is inserted and when the recording medium is ejected.

[Problems to be solved by the invention]

However, as a matter of course, the ability of the cleaning means to remove dirt decreases as the number of times of cleaning increases.

Therefore, an object of the present invention is to provide an information recording / reproducing apparatus having a cleaning means having a long life by reducing the cleaning operation as compared with the conventional apparatus.

[Means and actions for solving the problem]

The present invention relates to an information recording / reproducing apparatus for recording / reproducing information on / from a card-shaped information recording medium, wherein cleaning means for removing stain on the surface of the medium in contact with the card-shaped recording medium prior to recording / reproducing the information And a moving means for moving the cleaning means so as to be separated from the card-shaped recording medium after the recording or reproduction of the information is completed.

With such a configuration, after recording or reproduction, the cleaning unit is separated from the recording medium and cleaning is not performed. This is because, even if cleaning is performed after recording or reproduction, the discharged medium is eventually stained, so that cleaning is not necessarily required.

Further, the cleaning unit and the moving unit are housed in a single housing, and the housing can be detached from the apparatus main body of the information recording / reproducing apparatus.

〔Example〕

FIG. 1 is a side view showing the internal configuration of an information recording / reproducing apparatus using the first embodiment of the present invention.

Reference numeral 1 denotes a main body, and an insertion slot 3 into which a card-shaped information recording medium 2 is inserted is provided on one side surface of the main body 1. Reference numeral 4 denotes a brush for removing dirt and dust adhering to the surface 2 of the card-shaped information recording medium near the insertion slot 3. It is installed vertically up and down so as to sandwich it. 5
Denotes a cleaning medium, and 6-1 and 6-2 denote pulleys A and B around which the belt-shaped cleaning medium 5 is wound. Reference numeral 7 denotes a drive roller provided along the transport path for transporting the card-shaped recording medium 2. 8-1 is the drive roller 7
A pad member 8-2 presses the cleaning medium 5 and presses it against the card-shaped recording medium. Reference numeral 8-2 denotes a spring for pressing the pad member 8-1.

Reference numeral 9 denotes a lever A for pushing up the cleaning medium after coming into contact with the card-shaped information recording medium 2 when the card-shaped information recording medium 2 is taken out. 10 is a card-shaped recording medium 2
The lever B is used to rotate when the pulley C11 rotates by rotating the pulley C11 by rotating the pulley C11. The gear 12 is
It is designed to work with A6-1. Reference numeral 13 denotes a shutter provided near the insertion slot 3 and opened and closed by a reaction of a sensor 14 for detecting insertion of the card-shaped information recording medium 2.

Since the information recording / reproducing apparatus according to the present invention is configured as described above, the card-shaped information recording medium 2 is inserted into the insertion slot 3
When it is inserted into the brush 4, it passes through the shutter 13 opened by the sensor 14 which has reacted, and comes into contact with the brush 4. The brush 4 first removes dust and dirt attached to the surface of the card-shaped information recording medium 2. Depending on the configuration of the brush 4, static electricity can be removed. In this case, brush 4
The brushes 4 are provided vertically above and below the card-shaped information recording medium 2 in the conveyance path of the card-shaped information recording medium 2 so as to sandwich both sides of the card-shaped information recording medium 2 so that the brushes 4 are card-shaped as shown in FIG. At the moment when they are pushed away from the information recording medium 2, they come into contact with each other, and dust and dirt attached to the brush 4 are removed by each other's brush.

The drive roller 7 rotates (rotates clockwise) by the reaction of the sensor 14, and conveys the card-shaped information recording medium 2 along the conveyance path of the card-shaped information recording medium 2. At that time, the card-shaped recording medium 2 first contacts the lever B10, and the lever B10
1 is rotated so that gear 12 and pulley A6-
1 rotates, and the cleaning medium 5 is rotated by the pulley A6-1.
And a unused portion of the cleaning medium 5 appears on the transport path of the card-shaped information recording medium 2. When the card-shaped information recording medium 2 passes between the drive roller 7 and the cleaning medium 5, fingerprints and oils on the surface of the card-shaped information recording medium are removed. The card-shaped information recording medium 2 is transported inside the main body while the surface is cleaned,
Recording or reproduction of information is performed.

When the card-shaped information recording medium 2 is ejected, first,
Abutting on A9, the lever A9 is pushed up to the upper left, and the cleaning medium 5 is pushed up together with the pad member 8-1.
When the card-shaped information recording medium 2 is inserted, the lever A9 comes into contact with the card-shaped information recording medium 2, but in this case, the lever A9 is pushed up to the upper right and is free, and the card-shaped recording medium 2 passes through as it is it can.

With the cleaning medium 5 and the pad member 8-1 pushed up, the card-shaped information recording medium 2 is carried by the drive roller 7 in a direction to be taken out. At this time, the lever B10 comes into contact with the card-shaped information recording medium 2, but the lever B10 is tilted to the upper left to become free and the card-shaped information recording medium 2 is ejected.

In this manner, cleaning can be performed only when the card-shaped information recording medium 2 is inserted. In addition, the cleaning medium 5 is used one after another (including the same portion only once, including a plurality of times).
Since it can be fed out, it is possible to prevent the same portion of the cleaning medium 5 from being excessively used. After the cleaning medium 5 has been used up, only the portion related to the cleaning medium 5 needs to be replaced. Therefore, it is convenient to replace the cassette by using the portion A within the dotted line shown in FIG. 1 as a cassette.

〔The invention's effect〕

As described above, the present invention provides a cleaning means for removing stains on the surface of a medium in contact with a card-shaped recording medium prior to recording or reproduction of information, and separating from the card-shaped recording medium after completion of recording or reproduction of information. And a moving means for moving the cleaning means. In other words, before recording or reproducing information, the medium is cleaned, so that a good recording or reproducing result is obtained. However, after recording or reproducing, the cleaning means is released, so that cleaning is not performed.
Therefore, the number of times of cleaning is reduced as compared with the related art, and the life of the cleaning unit is prolonged.
