Description

[Detailed description of the invention] [Industrial application field] The invention relates to a card processing device that performs processing such as reading information recorded on a card or writing information to a card. The present invention relates to an improvement in a card transport device for guiding a card to the card processing device and for taking out the card from the card processing device.

[Conventional technology]

In general, a card-shaped optical card (hereinafter simply referred to as a card) is used as a recording medium of an optical information recording / reproducing apparatus for writing information using a light beam (laser beam) and reading recorded information using the light beam. Has been proposed.

On the other hand, read the information recorded on such a card,
Alternatively, in a card processing device that performs processing such as writing information to a card, it is necessary to move the card relative to an optical head that reads and writes information recorded on the card. For example, a card processing apparatus 1 having a card holder as shown in a conceptual perspective view of FIG. 7 and reciprocating the card holder has been proposed.

The card processing apparatus 1 includes a pair of guide shafts 2 and 3 arranged at predetermined intervals in parallel with each other and in the same direction, and a pair of guide shafts 2 and 3 on the pair of guide shafts 2 and 3. And a card holder 4 that slides in the direction of extension of the card holder 3 and reciprocates. The card 5 is delivered to the card holder 4 by a card transport device, which will be described later. The card is received and discharged to the outside of the card processing device 1.

On the other hand, a pair of bearing members 6 and 7 are fixed to the lower surface of the card holder 4 in parallel with each other, and the bearing members 6 and 7 have bearing holes 6a into which the guide shafts 2 and 3 are inserted. , 7a are formed one by one.

And, the card holder 4 is used for the card holder 4.
The guide shaft 2 is moved by a card holder moving means 14 including a rack 11 fixed to the lower surface, a pinion 12 meshing with the rack 11, and a motor 13 for driving the pinion 12.
3 reciprocate along the extension direction (direction of arrow A).

On the other hand, the optical head 8 is supported by a guide shaft 9 which is disposed parallel to and perpendicular to the pair of guide shafts 2 and 3 of the card holder 4. The card travels along the guide shaft 9 in a direction perpendicular to the moving direction of the card holder 4 (the direction of arrow B).

The optical head 8 is formed on the upper surface of the card 5 due to the relative position change between the reciprocating travel of the card holder 4 and the optical head 8 traveling in a direction perpendicular to the moving direction of the card holder 4. The information is read by scanning the surface of the storage area 5a, and the information is written into the storage area 5a by the optical head 8.

Note that the recording width (track pitch) of an information unit (hereinafter, referred to as a pit) recorded in the storage area 5a of the card 5 is extremely narrow (about 10 to 12 μm). An extremely high relative positioning accuracy between the optical head 4 and the optical head 8 is required.

On the other hand, the conventional card transport device 20 for delivering the card 5 to the card holder 4 of the card processing apparatus 1 and receiving and discharging the card 5 from the card holder 4 is, as shown in a conceptual partial sectional view of FIG. , A card guide 23 having an insertion slot 21 and a discharge slot 22 for the card 5, and a feed roller mechanism disposed immediately after the discharge slot 22 of the card guide 23.
24.

The feed roller mechanism 24 is a driving roller that is rotated at a predetermined timing by driving means such as a motor (not shown).
The driving roller 25 and the driven roller 26 are configured to be opened and closed by a solenoid plunger 27 that operates at a predetermined timing and a link mechanism 28.

The link mechanism 28 described above has a substantially T
The upper link 29 is rotatably supported by a shaft 31 and the lower link 30 is supported by a shaft 32. The upper link 29 is rotatably supported by a shaft 31 and the lower link 30 is supported by a shaft 32. Have been. A guide groove 29 is provided at a predetermined position of these upper and lower links 29, 30.
a (the other is not shown) is formed, and a pin 3 implanted in an operating shaft 27a of the solenoid plunger 27 is provided in the guide groove.
3 are engaged.

When the solenoid plunger 27 is not energized, the operating shaft 27a moves leftward in the drawing by the urging force of a coil spring (not shown) as shown in FIG. The space between the drive roller 25 and the driven roller 26 is maintained in an expanded state.

Next, the operation of the above-described conventional card transport device 20 will be described.

At the initial position of the card transport device 20 shown in FIG. 8, the card holder 4 is waiting at a position close to the outlet 23 of the guide 23, and the drive of the card transport device 20 and the driven rollers 25, 26 It is maintained in a stand-by state separated by a solenoid plunger 27.

At the initial position shown in FIG. 8, when the card 5 is inserted into the insertion slot 21 in the direction of the arrow, based on a detection signal of a sensor (not shown) for detecting the presence or absence of the card, as shown in FIG. The drive current is supplied to the solenoid plunger 27, and the operating shaft 27a moves to the right in the drawing, and the link mechanism 28
The drive roller 25 and the driven roller 26 are brought into close contact with each other via a motor, and a motor (not shown) is operated to drive the drive roller 25 forward (clockwise).

As shown in FIG. 9, when a drive current is supplied to the solenoid plunger 27 and the above-described drive roller 25 rotates forward, as shown in FIG. 10, the card 5 applies the transport force of the drive roller 25 and the driven roller 26 as shown in FIG. Is drawn into a predetermined position in the card holder 4. When the card 5 is positioned and stored in a predetermined position in the card holder 4, the operation of the motor for driving the drive roller 25 is stopped by the detection signal of a sensor (not shown) for detecting the fact, and the solenoid plunger is stopped. Power supply to 27 is also stopped.

When the rotation of the drive roller 25 is stopped and the power supply to the solenoid plunger 27 is stopped, the space between the drive roller 25 and the driven roller 26 is expanded as shown in FIG. The transfer of the card 5 to 4 is completed.

Thereafter, the card holder 4 reciprocates while holding the card 5 as shown in FIG. 12, and the information stored in the card 5 is read by the optical head 8 of the card processing apparatus 1 shown in FIG. Information is written in the storage area 5a.

During the process of writing information to the card 5 or the like, that is, while holding the card 5, the card holder 4
12, the drive roller 25 and the driven roller 26 of the card transport device 20 are kept in an expanded state as shown in FIG. 12, and the card 5 and the driven roller 25 or the card 5 and the driven roller 26 and not to collide.

When the reading and writing processes of the information of the card 5 are completed, the card holder 5 returns to the initial position close to the outlet 22 of the guide 23 again as shown in FIG. 13, and stops at that position. Then, a drive current is supplied to the solenoid plunger 27 as shown in FIG. 14 based on a detection signal of a sensor (not shown) for detecting the fact, the operating shaft 27a moves to the left side of the drawing, and Drive roller
The drive roller 25 rotates in the reverse direction (counterclockwise) based on the detection signal, and moves the card 5 backward to receive the card 5 from the card holder 4 while bringing the card 5 into close proximity to the driven roller 26. . Then, as shown in FIG. 15, when the card 5 is ejected to the outside of the guide 23, the driving roller 25 and the driven roller 26 of the card transport device 20 are driven based on a detection signal of a sensor (not shown) for detecting the fact. Are separated from each other and stopped, and return to the initial position similar to FIG.

[Problems to be solved by the invention]

By the way, according to the above-described conventional card transport device 20, when the card 5 is delivered to the card holder 4 and the card 5 is received from the card holder 4, the solenoid plunger 27 causes the drive roller 25 and the driven roller 24 to be moved each time. Since the operation of opening and closing the card is performed, the process of receiving and transferring the card to and from the card holder is delayed, so that the processing speed of the entire card processing apparatus cannot be improved.

In addition, in order to solve the above-mentioned problem,
As in 3975 Publication, the medium is gripped and transported by a feed roller having a notch and a pinch roller having no notch,
There is also a device in which the conveyance of the medium is released by a gap formed between the rollers when the notched portion of the feed roller faces the medium, but the card described in Japanese Patent Publication No. 51-13975 discloses a card. When applied to a transport device, because of the structure in which only one of the pair of rollers has a notch, even after releasing the transport of the card, a part of the card always contacts the roller without the notch, For this reason, after the card is positioned and stored in the holder, when the holder is reciprocated, a part of the card contacts or abuts the pinch roller side without the notch, so that the card is accurately positioned and stored in the holder. This makes it impossible to receive accurate information and write accurate information.

Also, when receiving the card positioned and stored in the holder, if the holder approaches the roller with no notch, the card abuts on the peripheral surface of the pinch roller, etc., and therefore only damages the card and the pinch roller. In addition, there is a possibility that the card cannot be smoothly received from the holder.

Further, the one described in Japanese Patent Publication No. 51-13975 discloses a configuration in which a transport medium is intermittently transported only by a feed roller having a notch and a pinch roller having no notch, so that the card is placed in a holder. There is also a problem that the card cannot be quickly and accurately stored, and the card can be quickly removed from the holder to improve the processing speed of the card processing device.

In view of the above circumstances, this invention allows the card to be accurately and quickly stored in the holder, allows the card to be quickly removed from the holder, and accurately positions the card in the holder even if the holder reciprocates. It is an object of the present invention to provide a card transport device that can be stored.

[Means for solving the problem]

In order to solve the above-mentioned problem, in the present invention, a card holder that positions and stores a card and reciprocates when performing processing such as reading information recorded on the stored card and writing information to the card. And, in a card processing device having at least a card transfer device for transferring a card to the card holder and receiving a card from the card holder, the card processing device is disposed to face each other so as to grip and transfer the card from upper and lower surfaces, And a pair of rollers each having a notch formed on the peripheral surface, when positioning and storing the card in the card holder and delivering the card, or when receiving the card positioned and stored in the card holder. , The notches are opposed to each other, and the card holder is positioned between the opposed notches,
The card accommodated in the card holder forms a gap at an interval where the card does not contact any of the pair of rollers, and the notch is intermittent with respect to the card due to the notch during the conveyance of the card due to the rotation of the pair of rollers. A main feed roller mechanism for providing a high card transfer force, and an intermittent card transfer force during the card transfer of the main feed roller mechanism, which is disposed adjacent to an upstream side of a card transfer path formed by the main feed roller mechanism. In order to compensate for this, a sub-feed roller mechanism comprising a pair of rollers, which are provided opposite to each other and have no cutouts, which are always gripped and transported from above and below, is provided.

[Action]

According to the card transport device described above, the card has a main feed roller mechanism including a pair of upper and lower rollers formed with a notch, and a sub feed roller mechanism including a pair of non-notched rollers disposed upstream of the main feed roller mechanism. And the card is conveyed while being held between them, so that the card is continuously conveyed in the card conveying path, quickly and accurately stored in the holder, and quickly taken out of the holder. Further, a notch is formed on each of the peripheral surfaces of a pair of rollers constituting the main feed roller mechanism, and when the notches are opposed to each other, the card stored in the card holder does not contact any of the notches. Since the gap is formed, even if the card is positioned and stored in the holder and then the holder is reciprocated, a part of the card does not contact or contact the pair of rollers.

〔Example〕

Hereinafter, an embodiment of the card transport device according to the present invention will be described in detail.

FIG. 1 is a conceptual partial cross-sectional view showing a card transport device 40 according to the present invention, and the same parts as those in FIGS. 7 to 15 are denoted by the same reference numerals.

The card transport device 40 is provided with a card guide 43 forming an insertion port 41 and a discharge port 42 of the card 5 and disposed immediately after the discharge port 42 of the card guide 43, and is driven at a predetermined timing by a driving unit described later. Main feed roller mechanism
44.

The main feed roller mechanism 44 includes a drive roller 45
And a driven roller 46 which is interlocked with the driving roller 45 via a gear mechanism and rotates at the same rotational speed and in opposite directions. Also, this main feed roller mechanism
Cutouts 45a and 46a are respectively formed along the axial direction on the peripheral surfaces of the drive roller 45 and the driven roller 46 that constitute 44, and the shapes of the cutouts 45a and 46a are as shown in FIG. When the notches 45a and 46a face each other on the card transport path, a gap t is formed at least between the thickness of the card 5 and the card holder 4 to be transported therebetween.
Is configured so that the card 5 stored therein does not contact any of the cutouts 45a and 46a.

In order to transport the card 5 in one direction, the driving roller 45 and the driven roller 46 rotate at the same rotational speed through the gear mechanism and in opposite directions to each other, but the notches 45a and 46a When the driving roller 45 and the driven roller 46 rotate in the opposite direction to convey the card 5, the driving roller 45 and the driven roller 46 are formed on the peripheral surfaces of the driving roller 45 and the driven roller 46 at positions always facing each other on the card conveying path. .

The rotation stop position of the driving roller 45 and the driven roller 46 is set at a timing plate 48 having a notch 47 fixed to one end of the driven roller 46 and rotating with the driven roller 46, and a notch of the timing plate 48. When the rotation of the driving roller 45 and the driven roller 46 is stopped by the sensor 49 (for example, a photo sensor) that detects the position of the position 47, the cutouts 45a and 46a always face each other on the card conveyance path, that is, Notch of timing plate 48
Stops at the position where 47 is detected.

On the other hand, immediately after the insertion slot of the card guide 43, the card 5
A sub-feed roller mechanism 50 for transporting the paper is provided.

The sub-feed roller mechanism 50 includes a driving roller 51 and a driven roller 52 disposed so as to be always in close contact with the peripheral surface of the driving roller 51 by the urging force of a spring or the like.

On the other hand, the drive roller of the main feed roller mechanism 44 described above
Driving means for driving the driving roller 51 and the driving roller 51 of the sub-feed roller mechanism 50 includes a motor 60 that is operated at a predetermined timing by a control device (not shown), and a belt 61 that transmits the driving force of the motor 60. The belt 61 includes a pulley 62 fixed to a drive shaft of a motor 60, a pulley 63 fixed to one end of a drive roller 45 of a main feed roller mechanism 44,
And is wound around a pulley 64 fixed to one end of the drive roller 51 of the sub feed roller mechanism 50.

Therefore, when the motor 60 of the drive means rotates, the drive rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 rotate via the belt 61 and the pulleys 62, 63, 64.

In FIG. 1, reference numeral 70 denotes a pair of plates provided at predetermined intervals for supporting the above-described elements (the other is omitted), and 71 denotes the presence or absence of the card 5 in the card guide 43. Is a sensor that detects

Next, the operation of the above-described card transport device 40 will be described, and the configuration will be described in more detail.

In the initial position of the card transport device 40 shown in FIG.
The card holder 4 is on standby at a position close to the outlet 43 of the guide 43 immediately after.

Further, the motor 60 of the driving means stops its operation, and in the stopped position, the driving roller of the main feed roller mechanism 44 is stopped.
The cutouts 45a and 46a of the driven roller 46 and the driven roller 46 face each other on the card transport path, and stop at a position where a gap t is formed therebetween. The driving roller 51 and the driven roller 52 of the sub-feed roller mechanism 50 also stop their operations.

When the card 5 is inserted into the insertion slot 41 of the card guide 43 at such an initial position of the card transport device 40,
Based on the detection signal of the sensor 71 for detecting the presence or absence of the card 5, the motor 60 operates to drive the drive rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 via the belt 61 in the clockwise direction as shown in FIG. To rotate. The driven roller 46 of the main feed roller mechanism 44 rotates counterclockwise in conjunction with the drive roller 45 via a gear mechanism (not shown).

As described above, when the drive rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 rotate clockwise, the card 5 is guided by the card guide 43, is pulled in, and the card holder 4 is pulled.
It is conveyed continuously inside.

The reason for providing the above-mentioned sub-feed roller mechanism 50 is that the card 5 can be delivered to the card holder 4 and the card 5 can be received from the card holder 4 by the main feed roller mechanism 44 alone. The drive roller 45 and the driven roller 46 have cutouts 45a and 46a, respectively.
At the position where 6a is opposed to each other, the card 5 cannot be transported, so that the transport of the card 5 is intermittent. Therefore, such unnatural running behavior of the card 5 is prevented and the transport of the card 5 is performed smoothly. This is to ensure.

Next, the card 5 is continuously conveyed into the card holder 4 by the drive rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 as shown in FIG. When it is positioned and stored in a predetermined position in the card holder 4, the fact is detected by a sensor (not shown) provided in the card holder 4.

Then, as shown in FIG. 3, the sensor 49 detects the notch 47 of the timing plate 48, and drives the driving means to stop the driving rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 at the detected position. The operation of the constituent motor 60 is stopped. Accordingly, as shown in FIG. 3, at the position where the drive rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 are stopped, the drive roller 45 of the main feed roller mechanism 44 is stopped.
And the notches 45a and 46a of the driven roller 46 are opposed to each other on the card transport path, and at the position where the card 5 stored in the card holder 4 forms a gap t that does not contact any of the notches 45a and 46a. It will stop.

Therefore, at the stop position of the drive roller 45 and the driven roller 46 of the main feed roller mechanism 44 shown in FIG. 3, the cutouts 45a and 46a of the drive roller 45 and the driven roller 46 face each other on the card transport path, and a gap t is formed. As a result, the grip of the card 5 is released, and the delivery of the card 5 to the card holder 4 is completed. Therefore, the card holder 4 is immediately held from the position shown in FIG. 4, the information stored in the card 5 is read by the optical head 8 of the card processing apparatus 1 shown in FIG. 7, and the information is written in the storage area 5a.

During the process of writing information to the card 5 and the like, the drive roller 45 of the main feed roller mechanism 44 constituting the card transport device 40 as shown in FIG.
And the driven roller 46 are connected to the card 5 stored in the card holder 4 on the card conveying path by the notches 45a and 46a facing each other.
Stops at a position where a gap t is formed that does not contact either of the cutouts 45a, 46a.

Therefore, even if the card holder 4 reciprocates, the card 5 does not collide with any of the notches 45a and 46a.
Maintains the state accurately positioned and accommodated in the card holder 4, and performs accurate information reading and accurate information writing processing on the card 5.

Then, when the reciprocation of the card holder 4 shown in FIG. 4 is stopped and the reading and writing processes of the information of the card 5 are completed, the card holder 4 is again placed immediately after the discharge port 42 of the guide 43 as shown in FIG. It returns to the initial position close to and stops at that position.

When the sensor (not shown) returns to the initial position where the card holder 4 has approached immediately after the discharge port 42 of the guide 43 and detects that the card holder 4 has stopped at that position, based on the detection signal, FIG. As shown by the driving means motor 60
Are rotated in reverse to rotate the respective drive rollers 45, 51 of the main and sub feed roller mechanisms 44, 50 in a counterclockwise direction to receive the card 5 from the card holder 4 and to insert the card 5 from the insertion opening 41 of the card guide 43 into the outside. Discharge to

In addition, as shown in FIG.
When the card is ejected from the insertion opening 41 of the card 43, the card 5
That is detected by the sensor 71 that detects the presence or absence of the, after that, the sensor 49 detects the notch 47 of the timing plate 48, and at the detected position, the drive rollers 45 of the main and sub feed roller mechanisms 44, 50, The operation of the motor 60 constituting the driving means is stopped to stop the operation of the motor 51. That is,
The card carrier 40 returns to the initial position shown in FIG.

Therefore, according to the above-described card conveying device 40, when the card 5 is transferred to and received from the card holder 4, the notches 45a and 46a of the driving roller 45 and the driven roller 46 constituting the main feed roller mechanism 44 are always conveyed. Since the state of stopping at the position where the gap t is formed oppositely on the road is maintained, when carrying out the work of transferring and receiving the card 5 to and from the card holder 4 as in the related art, the drive roller and the driven roller There is no operation for opening and closing the space, so that the card 5 can be quickly delivered to and received from the card holder 4.

In the above embodiment, the main feed roller mechanism 44 is configured by the drive roller 45 and the driven roller 46 that is driven by the drive roller 44 via a gear mechanism.However, the present invention is limited to the above embodiment. Notches are formed in the peripheral surface of the main feed roller mechanism 44, and synchronized with each other,
Further, it may be constituted by a pair of drive rollers which rotate in opposite directions at the same rotation speed to convey the card.

[Effect of the invention]

As described above, according to the card transport device of the present invention, the card has a main feed roller mechanism composed of a pair of upper and lower rollers each having a notch, and a card having no notch disposed upstream of the card transport path. The card is gripped and conveyed between the sub-feed roller mechanism consisting of a pair of rollers, so that the card is smoothly and continuously conveyed, is quickly and accurately stored in the holder, and is quickly taken out of the holder. Therefore, the card processing speed of the card processing device can be further improved. A notch is formed on each of the peripheral surfaces of the pair of rollers of the main feed roller mechanism, and when the notches are opposed to each other, an interval in which the card stored in the card holder does not contact any of the notches. Since the gap is formed, even after the card is positioned and stored in the holder, even if the holder is reciprocated, a part of the card does not contact or abut on any of the pair of rollers, For this reason, the card is accurately positioned and stored in the holder,
It is possible to provide a card processing device that receives accurate information and writes accurate information.
