Abstract

PURPOSE:To prevent the damaging of a recording media surface and to effectively execute a cleaning by winding a cleaning member having a spiral groove to a cleaning roller and cleaning the shifting card-shaped information recording media. CONSTITUTION:At the freely rotatable cleaning roller 5, the cleaning member 6 having the spiral groove 66 is fitted, and the shifting card-shaped recording medium to record and reproduce the information are cleaned. The cleaned dust, etc., are shifted along the groove 66 and removed to the outside of the recording media. Consequently, without damaging by the dust, etc., where the recording media surface is cleaned, the effective cleaning is executed.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to an information recording and reproducing device that records or reproduces information on a card-shaped information recording medium, and particularly relates to an information recording and reproducing apparatus that records or reproduces information on a card-shaped information recording medium, and particularly relates to an information recording and reproducing apparatus that records or reproduces information on a card-shaped information recording medium. The present invention relates to an information recording/reproducing device having a cleaning mechanism for removing oil and the like.

(Prior Art) Conventionally, in this type of information recording/reproducing device, a cleaning mechanism for completely removing dust, fingerprints, oil, etc. adhering to an information recording medium has, for example, alternately provided convex portions and concave portions in the card insertion path. There is a method of cleaning in which cleaners made of a soft material arranged on the sides are placed opposite each other, and the card is sandwiched between the convex and concave portions of the cleaner.
No. 902.

However, in the cleaning mechanism described above, since the cleaner that cleans the card is fixed, cleaning is performed only at the tip of the cleaner that comes into contact with the card, so the cleaner gets dirty quickly and has a short lifespan. Additionally, if there was a relatively large amount of dirt between the cleaner and the card, the cart could be damaged during cleaning.

(Problems to be Solved by the Invention) The present invention has been made for the purpose of solving the problems of the above-mentioned conventional example,
It is an object of the present invention to provide an information recording and reproducing device that can effectively perform cleaning and IJ-ning of an information recording medium without damaging the card surface with dust.

(Means for Solving the Problems) As a means for solving all of the above problems, the present invention records or reproduces information by moving a card-shaped information recording medium relative to a recording or reproducing head. In the information recording and reproducing device, a rotatable cleaning roller is provided in the information recording medium transport path, and a cleaning member having a spiral groove for completely cleaning the information recording medium is attached to the cleaning roller. It is something to do.

(Example) Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In the first embodiment shown in FIGS. 1 to 3, 1 is a main body, and one side of the main body 1 is provided with an insertion slot 3 into which a card-shaped information recording medium 2 is inserted. Reference numeral 4 denotes a brush arranged on the information recording medium transport path. Reference numeral 5 denotes a rotatable cylindrical cleaning roller disposed on the information recording medium transport path behind the brush 4. The cleaning member 6 (l″i,
It is attached to the surface of the cleaning roller 5 with a spiral gap Th6 such that a spiral groove 6a is formed (see FIG. 2). Reference numerals 7, 7a, 7b, and 7c are drive rollers for conveying the information recording medium 2, 8.8a is a driven roller, the cleaning roller 5, the drive roller 7, and the drive roller 7a.

7c and the driven rollers 8, 8a are arranged in pairs, one above the other. Reference numeral 9 denotes a recording or reproducing head that records or reproduces information on the information recording medium 2. 10
．． 10a is a photosensor that detects the presence or absence of the information recording medium 2 and controls the rotation direction of the drive rollers 7+7a, 7b, and 7c.

The information recording and reproducing apparatus according to the present invention is configured as described above, and when the information recording medium 2 is inserted into the insertion slot 3, relatively large dust etc. attached to the surface of the information recording medium 2 is removed by the brush 4. Ru.

When the photo sensor 10 fully detects that the information recording medium 2 has been inserted, the drive roller 7 rotates (clockwise) and the information recording medium 2 is conveyed to the information recording medium conveyance path. At this time, the cleaning roller 5 is rotated in the opposite direction (clockwise rotation) of the drive roller 7 (clockwise rotation) and faster than the rotational speed of the drive roller 7.

Then, the cleaning member 6 attached to the surface is brought into contact with the information recording medium 2, and cleaning is performed by wiping off dust, fingerprints, oil, etc. adhering to the information recording medium 2. Further, relatively small dirt not removed by the brush 4 is removed by a spiral groove 6a formed in the cleaning member 6.
be removed from the information recording medium 2 along the lines. Next, the information recording medium 2 is conveyed under the recording or reproducing head 9 by the drive rollers 7.7a, 7b+7c and the driven rollers 8, 8a, and information is recorded or reproduced. When the recording or reproduction of the information is completed, the photo sensor 108 detects this, and the drive rollers 7.7a, 7b, 7c are rotated in the opposite direction (rotated counterclockwise) to remove the information recording medium 2 from the insertion slot 3. It can be taken out.

The cleaning member 6 is attached to the cleaning roller 5 with a spiral gap therebetween to form a spiral groove 6a, but as shown in FIG. The spiral grooves 6bi may be formed by attaching the grooves so that their end surfaces overlap in a spiral manner.

Further, the rotational direction and rotational speed of the cleaning roller 5 are not limited to those in the above embodiments, and as long as the rotational speed is different from the rotational speed in the rotational direction (clockwise rotation) in which the drive roller 7 conveys the information recording medium 2, The direction of rotation may be the same. Furthermore, if the rotation directions are different, the information recording medium 2 can be cleaned effectively even if the rotation speed is the same or slow.

FIG. 4 shows the entire second embodiment of the present invention, and the same members as those in the first embodiment are denoted by the same reference numerals and their explanations will be omitted. In this embodiment, instead of attaching the cleaning member 6 having a spiral groove 6ai to the cleaning roller 5, a spiral groove 6a is provided between the opposing cleaning rollers 5. A belt-shaped cleaning member 11 made of elastic material such as leather is attached. In this case as well, the same effect as that of the cleaning member 6 described above is performed.

(Effects of the Invention) As explained above, the information recording/reproducing apparatus according to the present invention has a spiral groove attached to a rotatable cleaning roller disposed in an information recording medium transport path. Since the cleaning member is configured to completely clean dust, fingerprints, oil, etc. adhering to the surface of the information recording medium, the cleaning member does not get dirty only in the part that comes into contact with the information recording medium, unlike a fixed type cleaner. Therefore, the service life can be significantly extended, and furthermore, the information recording medium can be cleaned effectively and easily.

In addition, dirt and other debris enters the spiral gap and is sequentially sent outward as the cleaning roller rotates, causing it to get caught between the card surface and the cleaning member and cause scratches on the card surface. I no longer have to worry about it.
