Abstract

PROBLEM TO BE SOLVED: To eliminate the need of a strong and large-sized carrying drive source, to perform miniaturization and to improve operability at the time of manual insertion of a recording medium. SOLUTION: Cleaning rollers 22 and 23 bisected in a direction transversal to the card carrying direction are arranged in series in the card carrying direction, carrying rollers 24 and 25 are arranged opposite to the respective cleaning rollers 22 and 23 so as to clamp the surface of a card C, and the surface of the card C is energized by the pressure F of a pressurizing spring 26. In such a manner, by dividing the cleaning rollers 22 and 23 into plural parts in the direction transversal to the card carrying direction and arranging them in series in the card carrying direction, maximum load resistance at the time of card insertion is reduced and the carrying drive source is reduced. Also, by dividing the cleaning rollers 22 and 23 and distributing load resistance force, a load is not applied at once at the time of the manual insertion, and hence the operability at the time of the insertion is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] 1. Field of the Invention [0002] The present invention relates to an information recording medium cleaning apparatus for optically or magnetically recording and reproducing information.

2. Description of the Related Art Conventionally, information recording media have been in the form of tapes, disks, cards, and the like, and are properly used depending on the purpose. Among them, cards are excellent in storage and portability. Therefore, it is widely used mainly for applications such as cash cards. In particular, the amount of information handled by optical cards reflects the recent information age, and the amount of information that can be handled is large, and existing magnetic cards cannot handle card systems that handle large-capacity information. It has become a problem and has attracted widespread attention because a card with high security is desired. The optical card has a large capacity of several megabytes compared to other cards, and is advantageous in that mass production is easy and inexpensive.
Furthermore, the optical card is a write-once recording medium, and since it is not possible to rewrite information that has been recorded once, it is difficult to falsify and a history remains, so that it is a recording medium with high security. Tracks are formed at intervals of several μm on this optical card, and information is recorded and reproduced by forming spots of several μm with a light beam between the tracks, and the optical card and the optical head are moved in a direction orthogonal to each other. There is known an information recording / reproducing apparatus which performs recording / reproducing by irradiating a light beam onto an optical card while following the track in parallel with a track. FIG. 5 shows a side view of a conventional optical card recording / reproducing apparatus. A card insertion slot 2 is opened on a side surface of the device housing 1, and inside the device main body 1, a transport unit for feeding an optical card C from the vicinity of the card insertion slot 2 and an optical card C are mounted. A card mounting table 3 which is a carriage that reciprocates linearly is arranged. An optical head 4 on which an optical pickup is mounted is disposed above the card mounting table 3 on the recording surface side of the optical card C. The transporting means for the optical card C includes a cleaning roller 5 and a transporting roller 6 which are arranged vertically opposite each other with a card insertion path therebetween, and a pair of transporting rollers 7. On the other hand, the mounting table 3 is connected to a belt 8, and the belt 8 is stretched on pulleys 9 arranged at predetermined intervals in parallel with the card insertion direction, and the pulley 9 is connected to a drive motor (not shown). The mounting table 3 has a light shielding plate 1
0 is attached, and the mounting table 3 moves between two locations detected by the optical means 11 and 12 fixed to the apparatus housing 1.
The linear reciprocating drive is performed in a direction parallel to the card insertion direction. When the card C is fed into the apparatus from the insertion slot 2 at the time of card insertion / ejection, the optical card C is sandwiched between the pair of the cleaning roller 5 and the conveying roller 6 and the pair of conveying rollers 7. The transport roller 6 is driven by the rotational force of the drive motor.
Is driven to rotate in the forward direction with respect to the insertion / ejection direction in conjunction with the transport roller pair 7, and the transport force causes the card C to be transported and mounted on the mounting table 3. As a result, the optical card C is held in a planar manner with respect to the mounting table 3, and is positioned and set so that the track direction is exactly parallel to the moving direction of the mounting table 3. Here, the laser light is focused on the optical card C while the optical head 4 moves linearly in a direction perpendicular to the moving direction of the card mounting table 3. As described above, by moving the mounting table 3 and the optical head 4 relatively, a predetermined recording / reproducing process is performed. When performing optical recording / reproducing of the card C, dirt such as dust adhering to the surface of the card C may cause performance degradation. For this reason, the cleaning roller 5 and the transport roller 6 pinch the card C with a predetermined pressing force, and when the card C is transported, the cleaning roller 5 stops rotating and the cloth wound around the roller surface is stopped. Slides on the surface of the card to wipe off the attached dust D.

However, in the above-mentioned conventional cleaning method using a cleaning member,
In order to apply a pressing force to the surface of the card between the cleaning roller 5 and the opposing transport roller 6, a load resistance acts when the card C is inserted. FIG. 6 shows a graph of the load resistance at this time, in which the horizontal axis represents the card C to be inserted.
The vertical axis represents the load resistance R applied to the card tip. At the position A when the leading edge of the card enters between the cleaning roller 5 and the transport roller 6, the riding resistance ROa acts, and thereafter, the sliding resistance R1a acts. Since the transport drive source needs to be selected in consideration of the riding resistance ROa, which is the maximum load, the transport drive source becomes large and the apparatus becomes large. There is also a method in which the card C is manually inserted until the card C passes through the cleaning roller 5 and then automatically conveyed by the conveying roller 6 provided at the back. In this case, the riding resistance ROa and the sliding resistance R1a are used. Have a problem that the operability at the time of inserting the card C becomes very poor. SUMMARY OF THE INVENTION It is an object of the present invention to provide an information recording medium cleaning apparatus which solves the above-mentioned problems, realizes downsizing without requiring a powerful and large-sized transport drive source, and further improves operability at the time of manual insertion. Is to do.

According to a first aspect of the present invention, there is provided an information recording medium cleaning apparatus for cleaning a surface of a card by sliding a cleaning member provided in a card transport path. The cleaning member is divided into a plurality of members in a direction transverse to the card conveying direction, and the cleaning members are arranged in front of and behind the card conveying direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a side view of the information recording / reproducing apparatus, FIG. 2 is a side view of the cleaning mechanism, and FIG. 3 is a plan view. An insertion slot 21 for inserting the card C is opened in the front surface 20a of the device housing 20. Insertion port 2
Cleaning rollers 22 and 23 divided into two parts in a direction transverse to the card conveying direction
Are arranged one after the other in the card transport direction. Each of the cleaning rollers 22 and 23 is opposed to the transport roller 24 so as to sandwich the surface of the card C,
The card C is urged by a pressing force F of a pressing spring 26. A ratchet gear 27 is provided coaxially with the cleaning rollers 22 and 23, and a ratchet claw 28 is provided near the ratchet gear 27.
Is attached. When the card C is inserted for cleaning, the ratchet pawl 28 comes into contact with the ratchet gear 27 so that the cleaning rollers 22 and 23 do not rotate. When the card C is ejected, the ratchet pawl 28 separates from the ratchet gear 27, and the cleaning rollers 22, 23 rotate in the card ejection direction. On the back side of the apparatus, a pair of transport roller pairs 29 for taking in the card C is provided. Further, a card mounting table 30, which is a carriage on which the card C is mounted and driven linearly reciprocally, is provided in the back of the apparatus. The mounting table 30 is connected to a belt 31, and the belt 31 is parallel to the card insertion direction. Pulleys 3 arranged at predetermined intervals
The pulley 32 is connected to a drive motor (not shown). A light-shielding plate 33 is attached to the mounting table 30, and the mounting table 30 extends between two locations detected by optical means 34 and 35 fixed to the apparatus housing 20 in parallel with the card insertion direction. It is designed to reciprocate linearly in the direction. Further, the mounting table 30 on the recording surface side of the card C
Above the optical head 36 equipped with an optical pickup.
Are arranged, and are linearly movable in a direction orthogonal to the moving direction of the card mounting table 30. With such a configuration, the card C is mounted on the mounting table 30 by the transport roller pair 29. A predetermined recording process is performed by condensing a laser beam from the optical head 36 onto the card C and moving the mounting table 30 and the optical head 36 relatively. FIG. 4 is a graph showing the load resistance when the card C passes through the cleaning member. The horizontal axis indicates that the card C is inserted through the insertion slot 21 and the cleaning rollers 22 and 23 are inserted.
The vertical axis represents the load resistance R applied to the card tip when cleaning the card at the tip of the card. Curve a is the load resistance when the cleaning roller 5 is not divided in the conventional example, curve b is the load resistance when the cleaning is performed by the cleaning rollers 22 and 23 divided in the width direction as in the embodiment, and curve c is the width. 6 shows load resistance when cleaning is performed with a cleaning roller divided into three in the direction. The position S1 on the horizontal axis is the position where the leading end of the card C enters between the cleaning roller 22 closest to the insertion port 21 and the transport roller 24 facing the position, and the position S2 is the second divided cleaning roller. The position when the leading end of the card C enters between the transfer roller 23 and the opposing conveying roller 25, and the position S3 is the position when the leading end of the card C enters between the third cleaning roller (not shown) and the opposing conveying roller. Each position is shown. As shown in the upper part of FIG. 4, the load resistance R0 at each of the positions S1, S2, S3 is such that the outer diameters of the cleaning rollers 22, 23 and the conveying rollers 24, 25 are equal,
Assuming that the angle at which each of the rollers 22 and 23 comes into contact with the tip of the card C is θ, and the pressing force applied to the card C is F,
R0 ≒ 2 · F · tan θ. After passing through the respective positions S1, S2, S3, the cleaning roller 2
Assuming that the friction coefficient of the cleaning rollers 22 and 23 is μ, the load resistance R1 when sliding the sliding rollers 2 and 23 is R1 ≒
It can be represented by μ · F. The pressing force F per unit length of the cleaning rollers 22 and 23 irrespective of the presence or absence of division
Are equal, one pressing force F when divided into two
Is 1/2 of the value before the division, and from the above equation, the load resistance R0 when the roller enters and the load resistance R1 when the roller slides.
Are also halved. In the case of two divisions, as shown by the curve b in FIG. 4, the load resistance R0 at the position S1 is 1/2 of the load resistance ROa before the division, and the load resistance R1 after passing through the position S1. Also becomes 1/2 of the load resistance R1a before the division. The maximum load resistance Rob at the position S2 is 1
The load resistance of sliding of the first-stage roller = R1a / 2 and the load resistance of entry of the first-stage roller = ROa / 2, which are smaller than the maximum load resistance ROa in the case of no division. . Further, in the case of three divisions, the load resistance R0 when entering one roller and the load resistance R1 during sliding both become １ ／ as shown by the curve c. And the position S
The maximum load resistance ROc at 3 is the addition of the first- and second-stage roller sliding load resistance = 2 · R1a / 3 and the third-stage roller entering load resistance = ROa / 3. It is possible to further reduce the maximum load resistance Rob at the time of division. Even if the card C is greatly deformed in the width direction, the pressing force F on the card surface is set to be somewhat high so that no wiping residue is left over the entire width of the card.
Since the card C only needs to cover the deformation amount corresponding to the width of the division by dividing as shown in 2, 23, the pressing force F may be smaller by that amount. Although the cleaning rollers 22 and 23 have the same pressing force F per unit length regardless of the division, the pressing force F per unit length can be set smaller by dividing. it can. As described above, the cleaning member is divided into a plurality of members in a direction transverse to the card conveyance direction, and the divided cleaning members are arranged before and after the card conveyance direction, so that the maximum load resistance at the time of card insertion is reduced. As a result, the transport drive source can be reduced.
Further, since the cleaning member is divided and the load resistance is dispersed, no load is applied at the time of manual insertion, so that the operability at the time of insertion is improved. Further, by the division, it is also possible to manually insert the cleaning roller 22 of the preceding stage and connect the transport roller 25 facing the cleaning roller 23 of the subsequent stage to the transport driving source to perform automatic transport. As a result, the insertion load is smaller than when performing all the manual cleaning, so that the operability of manual insertion is improved, and the load resistance can be reduced as compared with the case of performing the full automatic cleaning. A drive source can be used. In this embodiment, the cleaning member is divided into two parts. However, dividing the cleaning member into three or more parts is more effective as described above. Further, although the cleaning member is divided evenly, the cleaning member may not be divided equally.

As described above, the apparatus for cleaning an information recording medium according to the present invention comprises a cleaning member divided into a plurality of members in a direction transverse to a card conveying direction.
By arranging them one after the other in the card transport direction, a low-power transport drive source can be used, and operability can be improved.

In this case, the riding resistance ROa and the sliding Since both the resistances R1a increase, there is a problem that the operability when inserting the card C is extremely deteriorated.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide an information recording medium cleaning apparatus which realizes downsizing without requiring a powerful and large transport driving source and further improves operability at the time of manual insertion.

[0012]

According to a first aspect of the present invention, there is provided an information recording medium cleaning apparatus for cleaning a surface of a card by sliding a cleaning member provided in a card transport path. The cleaning member is divided into a plurality of members in a direction transverse to the card conveying direction, and the cleaning members are arranged in front of and behind the card conveying direction.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a side view of the information recording / reproducing apparatus, FIG. 2 is a side view of the cleaning mechanism, and FIG. 3 is a plan view. An insertion slot 21 for inserting the card C is opened in the front surface 20a of the device housing 20. Insertion port 2
Cleaning rollers 22 and 23 divided into two parts in a direction transverse to the card conveying direction
Are arranged one after the other in the card transport direction. Each of the cleaning rollers 22 and 23 is opposed to the transport roller 24 so as to sandwich the surface of the card C,
The card C is urged by a pressing force F of a pressing spring 26.

A ratchet gear 27 is provided coaxially with the cleaning rollers 22 and 23.
A ratchet claw 28 is attached in the vicinity of. When inserting and cleaning the card C, the ratchet pawl 28
Abuts on the ratchet gear 27 so that the cleaning rollers 22 and 23 do not rotate. When the card C is ejected, the ratchet pawl 28 separates from the ratchet gear 27, and the cleaning rollers 22, 23
Are rotated in the card ejection direction.

At the back of the apparatus, a pair of transport rollers 29 for taking in the card C is provided. Further, a card mounting table 30, which is a carriage on which the card C is mounted and which is driven in a linear reciprocating manner, is provided in the back of the apparatus.
Reference numeral 0 is connected to a belt 31. The belt 31 is stretched on pulleys 32 arranged at predetermined intervals in parallel with the card insertion direction, and the pulleys 32 are connected to a drive motor (not shown). A light-shielding plate 33 is attached to the mounting table 30, and the mounting table 30 extends between two locations detected by optical means 34 and 35 fixed to the apparatus housing 20 in parallel with the card insertion direction. It is designed to reciprocate linearly in the direction. Further, an optical head 36 equipped with an optical pickup is arranged above the mounting table 30 on the recording surface side of the card C, and can move linearly in a direction orthogonal to the moving direction of the card mounting table 30. Have been.

With such a configuration, the card C is mounted on the mounting table 30 by the transport roller pair 29. The laser beam is condensed from the optical head 36 onto the card C, and
A predetermined recording / reproducing process is performed by relatively moving the optical head 36 with the optical head 36.

FIG. 4 is a graph showing the load resistance when the card C passes through the cleaning member. The horizontal axis shows the card C inserted through the insertion slot 21 and the cleaning roller 22,
The position of the leading end of the card when cleaning at 23, and the vertical axis is the load resistance R applied to the leading end of the card. Curve a represents the load resistance in the case of the conventional undivided cleaning roller 5,
A curve b indicates the load resistance when cleaning is performed by the cleaning rollers 22 and 23 divided in the width direction as in the embodiment, and a curve c indicates the load resistance when cleaning is performed by the cleaning roller divided into three in the width direction. I have.

The position S1 on the horizontal axis is the position of the transport roller 2 opposed to the cleaning roller 22 closest to the insertion port 21.
4, the position at which the leading end of the card C enters, the position S2 is the second divided cleaning roller 23
And position S3 when the leading end of the card C enters between the third cleaning roller (not shown) and the facing conveying roller. Are respectively shown.

The load resistance R0 at each of the positions S1, S2, S3 is, as shown in the upper part of FIG.
Assuming that the outer diameters of the rollers 2 and 23 and the conveying rollers 24 and 25 are equal, the angle at which the rollers 22 and 23 contact the leading end of the card C is θ, and the pressing force applied to the card C is F, R0
≒ 2 · F · tan θ. Further, after passing through the respective positions S1, S2, S3, the cleaning roller 22,
When the frictional coefficient of the cleaning rollers 22 and 23 is μ, the load resistance force R1 when sliding the sliding roller 23 is R1 ≒ μ ·
It can be represented by F.

Assuming that the pressing force F per unit length of the cleaning rollers 22 and 23 is the same regardless of the presence or absence of division, one pressing force F in the case of dividing into two is に 対 し て of that before the division. From the above equation, both the load resistance R0 when entering the roller and the load resistance R1 during sliding are halved.

In the case of two divisions, as shown by the curve b in FIG. 4, the load resistance R0 at the position S1 is の of the load resistance ROa before division, and the load resistance after the position S1 has passed. The resistance R1 is also １ ／ of the load resistance R1a before the division. The maximum load resistance Rob at the position S2 is the sum of the load resistance of the first-stage roller sliding = R1a / 2 and the load resistance of the first-stage roller entering = ROa / 2, It is smaller than the maximum load resistance ROa when not divided.

Further, in the case of three divisions, the load resistance R0 when entering one roller and the load resistance R1 during sliding both become １ ／ as shown by the curve c. Then, the maximum load resistance ROc at the position S3 is the sum of the first-stage and second-stage roller sliding load resistance = 2 · R1a / 3 and the third-stage roller entry load resistance = ROa / 3. Thus, it is possible to further reduce the maximum load resistance Rob at the time of division into two.

Even if the card C is greatly deformed in the width direction, the pressing force F on the card surface is set to be somewhat high so that there is no wiping residue over the entire width of the card. By dividing as described above, the card C only needs to cover the deformation amount corresponding to the width of the division, so that the pressing force F may be smaller by that amount. In addition,
The cleaning rollers 22 and 23 are irrespective of whether they are divided or not.
Although the pressing force F per unit length is set to be equal, the pressing force F per unit length can be set smaller by dividing.

As described above, the cleaning member is divided into a plurality in the direction transverse to the card conveying direction, and the divided cleaning members are arranged one after the other in the card conveying direction. The resistance can be reduced, and as a result, the transport driving source can be reduced. In addition, since the load resistance is distributed by dividing the cleaning member, no load is applied at the time of manual insertion, so that the operability at the time of insertion is improved.

Further, by dividing, it is also possible to manually insert the cleaning roller 22 of the preceding stage and to connect the transport roller 25 facing the cleaning roller 23 of the subsequent stage to the transport driving source to perform automatic transport. is there. As a result, the insertion load is smaller than when performing all manual cleaning, so that the operability of manual insertion is improved, and the load resistance can be made smaller than when fully automatic insertion, so that a smaller transport A drive source can be used.

In this embodiment, the cleaning member is divided into two parts. However, dividing the cleaning member into three or more parts is more effective as described above. Further, although the cleaning member is divided evenly, the cleaning member may not be divided equally.
