Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning means for an information recording / reproducing apparatus for optically recording / reproducing information using a card-shaped recording medium (optical card).

[0002]

2. Description of the Related Art An optical card has a storage capacity several thousand to 10,000 times larger than a magnetic card and cannot be rewritten like an optical disk, but the storage capacity is as large as 1 to 2 Mbytes. A wide range of applications is conceivable as a bankbook, a map for mobile phones, a prepaid card used for shopping, etc. An information recording / reproducing apparatus using this optical card generally adopts a roller driving system in which an optical card is conveyed by a driving roller which is a conveying means having an elastic roller to record / reproduce information.

In this roller drive type information recording / reproducing apparatus, when the surface of the optical card is inserted into the apparatus with dirt such as oil or dust on the user's hand attached and the driving roller is driven, the dirt is driven. Transferred to the roller. If dirt accumulates on the surface of the drive roller due to long-term use, the drive roller slips on the optical card, and the optical card cannot be conveyed properly.

In order to solve such a problem, a cleaning card for cleaning the optical card carrying means has been proposed. For example, JP-A-20539
In Japanese Patent Laid-Open No. 1-2003, the main body of the device is turned off, the electric motor is unlocked, and the cleaning card is manually inserted into and removed from the device repeatedly. The content of cleaning by attaching dust that is present is disclosed.

Further, the information recording / reproducing apparatus is provided with an optical head which operates when optically recording / reproducing information, but this optical head is generally apt to cause trouble due to adhesion of dust. In particular, dust is likely to adhere to the objective lens arranged opposite to the optical card inserted from the outside of the apparatus, and this adhesion causes a problem that proper recording / reproduction of information cannot be performed.

To solve these problems, a cleaning card for cleaning the objective lens has been proposed. For example, in Japanese Utility Model Laid-Open No. 5211/1982, a member having a function of cleaning an optical head by a polishing action and a wiping action is provided on the surface of a base sheet inserted from a card insertion port of the apparatus, and this cleaning member is It is disclosed that the optical head portion is cleaned while being brought into contact therewith.

[0007]

In the conventional cleaning card described above, it is necessary to separately prepare a cleaning card for cleaning the optical card conveying means and for cleaning the objective lens, which causes a problem of increasing cost. is there. In addition, there is a risk that the two types of cleaning cards may be mistakenly used. Further, since the cleaning card for cleaning the objective lens is configured to be cleaned by moving in contact with the portion of the objective lens, the cleaning card and the objective lens may be hooked and come into contact with each other. Then, an unexpected force may be applied to the objective lens movably supported by the optical head by a wire or the like, and the objective lens and the lens support may be damaged.

The present invention is proposed in order to solve the above-mentioned problems, and it is possible to clean the optical card conveying means and the objective lens with a single cleaning card and record information without damaging the object to be cleaned. The purpose of the present invention is to provide a cleaning device for a reproducing device.

[0009]

In order to achieve the above object, the present invention provides a means for conveying an information recording card in an information recording / reproducing apparatus and an optical head for optically recording / reproducing information on / from the information recording card. In a method of cleaning an information recording / reproducing apparatus for cleaning an objective lens provided opposite to a card conveying surface, a cleaning card is inserted into the information recording / reproducing apparatus after the objective lens is retracted from the card conveying path surface. The cleaning card is stopped at a predetermined position, and then the transportation means is cleaned while sliding at least one surface of the cleaning card and the transportation means. The retracted state is released and the objective lens and at least one surface of the cleaning card are brought into sliding contact, and a slight vibration force is applied to the objective lens in the required direction. It was Cleaning of the information recording and reproducing apparatus designed to clean the objective lens by the. In addition, at least the objective lens cleaning member is provided on one surface of the card-shaped card body, and at least the information recording card conveying means cleaning member is provided on the other surface of the card body, and information is provided near the rear end of the card body in the insertion direction. A cleaning card for use in a method for cleaning an information recording / reproducing apparatus, which is provided with a stopper portion for stopping excessive insertion into the recording / reproducing apparatus.

Next, the cleaning of the drive rollers 7 and 14 and the objective lens 24 of the apparatus thus constructed will be described. The cleaning card used in this embodiment is shown in FIG.
It is configured as shown in. Cleaning card 25
Projecting portions 26 are formed on both sides of the rear end portion in the insertion direction (arrow) of the main body so as to project in the card width direction. In addition, the surface of the cleaning card 25 that remains in the vicinity of the protrusion 26 is divided into three parts in parallel with both sides of the card, and a first cleaning member 27 is provided in the center. Second cleaning members 28 are provided on the strip-shaped portions on both sides of the first cleaning material 27. The width of the first cleaning member 27 is at least the objective lens 24.
Is larger than the diameter of the drive roller 7, 14 and the width of the second cleaning member 28 is larger than the width of each of the drive rollers 7 and 14.

The first cleaning member 27 is for cleaning the objective lens 24 of the optical head 23, and the second cleaning member 28 is the dust attached to the first and second driving rollers 7, 14. It is for removing oil and oil. Such a cleaning member is similarly provided on the back surface of the cleaning card 25.

FIG. 4 shows a state in which the vicinity of the optical card transport path is cleaned using the cleaning card 25.
For cleaning, a cleaning mode as shown in FIG. 5 is set. First, when the cleaning card 25 is inserted through the insertion port 3, the first sensor 5 detects the front end portion 25 a of the cleaning card 25 in the insertion direction. Then, the motor 6 is driven, and at the same time, the objective lens actuator (not shown) in the optical head 23 is driven to retract the objective lens 24 in the direction away from the cleaning card transport path. Then, the first drive roller 7 and the second drive roller 14 rotate in the clockwise direction, and the cleaning card 25 causes the first drive roller 7 and the first pressure roller 1 to move.
It is sandwiched by 0 and transported inside the apparatus (FIG. 5A).

Next, at the moment when the front end portion 25a of the cleaning card 25 in the insertion direction passes the third sensor 13, T =
A timer (not shown) starts counting the elapsed time T (FIG. 5B). When the front end portion 25a of the cleaning card 25 in the insertion direction is sandwiched between the second driving roller 14 and the second pressing roller 21, these rollers try to further convey the cleaning card 25 into the apparatus. In this case, after a certain point when T = t ′,
The protruding portion 26 of the cleaning card 25 contacts the insertion opening 4 to prevent the cleaning card 25 from being inserted further. However, since the motor 6 tries to further convey the cleaning card 25 to the inside of the apparatus, the first driving roller 7 and the second driving roller 14 serve as the second cleaning member 28 provided on the back surface of the cleaning card 25. By sliding, the stains on the rollers are removed.

On the other hand, the first cleaning member 27 provided on the surface of the cleaning card 25 is the optical head 23.
It is located just below the objective lens 24 of FIG. Therefore, after a preset time t ₀ when T = t ₀ (t ₀ > t ′) has passed, an unillustrated objective lens actuator in the optical head 23 is energized to convey the cleaning card of the objective lens 24. The withdrawal from the road is released to bring it into contact with the first cleaning member 27. In this state, by driving the objective lens 24 so as to slightly vibrate in the T _r direction and the F _o direction, the objective lens 24 and the first cleaning member 27 slide, and the dirt of the objective lens 24 is removed. (FIG. 5C).

Next, after a preset predetermined time such that T = t ₁ (t ₁ > t ₀ ), the objective lens actuator (not shown) in the optical head 23 is re-energized to obtain the objective. After the lens 24 is retracted in the direction away from the cleaning card transport path, the motor 6 is rotated in the opposite direction to eject the cleaning card 25 (FIG. 5D). Then, when the rear end portion 25a of the cleaning card 25 in the ejection direction is detected by the first sensor 5, the first sensor 5 stops the driving of the motor 6 (FIG. 5E). At this time, since the cleaning card 25 is partially projected to the outside of the insertion opening 4, the user can grab and remove the protruding cleaning card, and the cleaning of the drive roller and the objective lens is completed. is there. Since the back surface of the cleaning card 25 has the same structure, the cleaning card can be replaced many times and inserted into the apparatus, so that cleaning can be performed many times with one card.

FIG. 6 and FIG. 7 show a second embodiment of the present invention. Parts corresponding to those of the first embodiment are designated by the same reference numerals (the same applies to the following embodiments). In this embodiment, the cleaning card 29 is constructed as shown in FIG. Card main bodies are provided on both sides of the vicinity of the protruding portion 30, and a first cleaning member 27 and a second cleaning member 28 are provided on the card main bodies on both sides, respectively, as in the first embodiment. As shown in FIG. 7, the cleaning card 29 configured as described above is used by inserting it into the apparatus. In this embodiment, since both sides of the card body can be used for cleaning, the cleaning card 29 of the first embodiment can be used. 2 compared to things
Can withstand double use. Further, since the portion protruding to the outside of the device is large, insertion into and removal from the device can be easily performed.

8 and 9 show a third embodiment of the present invention. In this embodiment, the cleaning card 31 is constructed as shown in FIG. This embodiment is the first
This is a modification of the embodiment, and a plurality of protrusions are provided near the rear end in the cleaning card insertion direction. As shown in FIG. 9, the cleaning card 31 configured as described above is used by inserting it into the apparatus. In this embodiment, the first drive roller 7 and the second drive roller 1 to be cleaned are used.
The protrusions 32 to 35 can be selectively used according to the distance from the protrusion 4. That is, when the distance between the first drive roller 7 and the second drive roller 14 is short as shown in FIG. 9, the first protrusion 32 near the front end in the insertion direction of the cleaning card 31 may be used. When the distance is the next longest, the first protrusion 32 is separated at the first separation portion 32a, and the second protrusion 33 is used. Similarly, when the fourth projecting portion 35 is used, the first projecting portion 32 to the third projecting portion 34 may be separated through the respective separating portions 32a to 34a.

The present invention is not limited to the above embodiment, but various changes and modifications can be made. For example, the present invention may be applied to an information recording / reproducing apparatus of a system in which an optical card is placed on an optical card mounting table to record / reproduce information. Further, in this embodiment, the drive rollers 7 and 14 for conveying the optical card 2 are arranged on the opposite side of the objective lens 24 with respect to the card (the back side of the card), but the same as the objective lens 24. It is obvious that the cleaning card 25 can be configured so as to obtain the same effect even if it is arranged on the side, that is, on the card surface side. Furthermore,
If the roller cleaning and the objective lens cleaning are performed at the same time, the cleaning time can be shortened, and the time can be greatly reduced compared to the case where two cleaning cards were used conventionally.

[0027]

As described above, according to the present invention, by driving a single cleaning card and an information recording / reproducing apparatus, both the card conveying means such as a driving roller and the objective lens of the optical head can be cleaned. Therefore, unlike the conventional case, it is not necessary to properly use the cleaning card depending on the cleaning location, the cost can be reduced, and the cleaning card is not mixed up. Also, when cleaning the objective lens, the cleaning card side is always stopped and the objective lens side is finely moved with an extremely small force, so that no unreasonable force is exerted on the objective lens, and tentative force is not applied. The addition does not damage the objective lens or the lens support.
