Abstract

PROBLEM TO BE SOLVED: To prevent occurrence of jam by conveying card with a mobile unit composed of a conveyer roller, intermediate roller and mobile roller. SOLUTION: A mobile unit 13 is constituted integrally with a frame body and provided freely movably in the direction of a card passage 23. Simultaneously with the insertion of card between a conveyer roller, the mobile unit moves in the direction of arrow (t) but when returning the card, the mobile unit moves in the direction of arrow (s). Three rollers 3, 2 and 1 are formed so as to be oppositely interlocked one and another and when any one of them is driven, the card can be conveyed. When the intermediate roller 2 is driven counterclockwise, the roller 3 sends the card just behind a shutter 26 to the deep end and the roller 1 moves a frame 16 in the direction of arrow (t). Therefore, a card 8 getting out of the shutter 26 is conveyed while being held between the conveyer roller 3 and the pad roller and during the conveyance, information signals are exchanged with the card.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card carrier for a card reader using a magnetic card, an IC card or an optical card. More specifically, the present invention relates to a transport mechanism in which the transport mechanism itself is movable.

[0002]

2. Description of the Related Art There are card readers for reading optical information and magnetic information recorded on cards such as magnetic cards, IC cards and optical cards. This card reader is used as an automatic reading device for telephone cards and various tickets in addition to automatically and efficiently issuing and processing prepaid cards, creating payment cards, and processing deposit and savings cards. A card carrying mechanism for carrying a card is attached to such a card reader.

FIG. 5 is a side view showing a carrying mechanism of a conventional card reader.

In the figure, a frame 21 is formed with a card passage 23 extending from a card insertion port 22 toward a card entrance direction. A pre-head 24 and a pad roller 25 are provided at a predetermined distance from the card insertion slot. The pad roller is rotatably supported, and a card is inserted into this gap through the card insertion port 22 and is transported. The pre-head discriminates the presence or absence of a card and the success or failure of the card. When the pre-head detects that the card is legitimate, a current is passed through a solenoid (not shown) to open the shutter 26.

The card is conveyed through the card path 23 in the direction of the arrow between the three pairs of conveying rollers consisting of the first, second and third conveying roller pairs 27, 28 and 29. Each of the pair of conveying rollers is composed of a driving roller and a driven roller and is arranged to face each other. In the transport mechanism shown in the figure, the drive rollers provided below the card passage are fixed to the rotary shafts pivotally supported by the side plates, and the rotary shafts are moved by a sensor that detects that a card has been inserted from the card insertion slot. The belt 3 is driven by a driving source 10, eg, a motor.
It is rotated through 0. On the other hand, each driven roller located above the card passage is supported by a pad block (not shown).

The card contact portion of the drive roller is set so as to slightly project to the card passage side from the lower virtual surface position of the card passage through which the lower surface 8-1 of the card will pass, and the first and second The gap formed by the third drive roller and the driven roller is about half the thickness of the card and is wider than the gap formed by the second drive roller and the driven roller, which facilitates the insertion of the inserted card.

When a regular card is inserted from the card insertion slot 22, the shutter 26 is opened and the card is placed in the first position.
The roller pair 27 is inserted into the gap, and the gap is closed by a card. Further, the drive source 10 is rotated by the sensor that detects the insertion of the card, and the drive roller is rotated. With the rotation of the driving roller, the driven roller rotates by receiving the contact resistance of the card, and the driving roller and the driven roller move the card to the second roller pair 28 while holding the card on the peripheral surface thereof.

When the leading edge of the card reaches the second roller pair 28 and is sandwiched in the gap formed by the driving roller and the driven roller, as described above, the gap between the second driving roller and the driven roller becomes larger. Since the gap between the first and third driving rollers and the driven roller is formed wider,
The contact resistance of the card received by the first driven roller disappears, and the card is substantially released from the pinch, and the card is conveyed in the card passage toward the third roller pair 29 by the rotational driving force of the second roller pair 28. It

The third roller pair 29 is the second roller pair 28.
Since the gap is wider than that of the third roller pair 29, when the leading edge of the card reaches the third roller pair 29, the rotation driving force of the second roller pair 28 facilitates the third roller pair 29. Is caught in the gap. When the trailing end of the card passes through the gap between the second roller pair 28, the rotational driving force becomes the third
The card is conveyed by being received from the roller pair 29. Then, in the course of this conveyance, the information of the card 8 is exchanged by the head 9 provided in the vicinity of the second conveyance roller pair 28.

When the drive roller is a rubber roller, it absorbs the difference in speed between the respective drive rollers, and also prevents the card from entering the roller pair and jumping away from the card roller pair. In order to prevent a speed difference from occurring at this time, the card is always driven by one roller as described above. In this case, the card is delivered from the roller that actually has the driving force to the roller that does not have the driving force. When the card plunges into the pair of rollers that do not have the driving force, the plunging load increases and the driving force decreases, which may cause a jam near the rollers that do not have the driving force. For this reason, there is a countermeasure using the platen transfer method (tray method), but in this case, the apparatus becomes complicated and large.

Further, when the rubber roller is used to convey the card, the drive roller, which is originally a perfect circle, also conveys the card while the diameter of the drive roller is apparently partially distorted when the card is clamped. Then, even if the first, second, and third pairs of conveying rollers are driven at the same number of rotations, a partial difference occurs in the conveying speed of the card. In addition, when the card is dirty with dust, oil, etc., the card may slip. these,
Fluctuations in the transport speed are undesirable for the transfer of prints in the head.

[0012]

Therefore, in the card conveying device of the present invention, when a card is transferred between rollers, a card conveying roller, an intermediate roller and a moving roller are provided in order to prevent occurrence of a jam or the like due to a reduction in driving force. The moving unit is configured to be linked with each roller, and by applying a driving force to one of the rollers, the moving unit is moved with respect to the fixed portion, and the card transport roller rotates. It is intended to solve the above-mentioned problems by transporting a card.

[0013]

A card carrier according to claim 1 of the present invention is a card carrier mechanism for transferring an information signal to and from a card while carrying a card inserted from a card insertion slot, and a moving unit. Is configured integrally so that the card transport roller, the intermediate roller, and the moving roller are interlocked with each other, and a driving force is applied to any one of the rollers to carry the card, and the moving unit is configured to move through the moving roller. The card is moved in the card path direction with respect to the fixed portion, and the card is carried by the card carrying roller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic view of a card carrying mechanism according to the present invention, which is contrasted with FIG. The members having the same functions as those of the conventional example will be described with the same reference numerals.

The moving unit 13 for carrying the card has a width m together with the carrying roller 3, the intermediate roller 2 and the moving roller 1 at the rear position of the pre-head 24 for discriminating the presence / absence of the card and the shutter 26 opened / closed by the information of the pre-head.
Is integrally formed with the frame body and is provided so as to be movable in the card passage 23 direction. Then, at least while the card 8 is waiting for insertion, it is moved to the position immediately after the shutter 26 by a control device (not shown) and moves in the direction of arrow t with the insertion of the card between the transport roller 3 and the pad roller 7. When returning the card, it moves in the direction of the arrow s. That is, the mobile unit 13 can move between s and t. By providing a distance n corresponding to the length of the card as this moving distance, it is possible to exchange information even if the information is recorded in the entire longitudinal direction of the card.

The conveying roller 3, the intermediate roller 2 and the moving roller 1 are formed so as to interlock with each other. Also,
It moves as a moving unit by driving any one roller. For example, when the intermediate roller 2 is rotated in the counterclockwise direction, the transport roller 3 feeds the card immediately behind the shutter 26 to the rear end, and the moving roller 1 causes the frame 1 to move.
6 is moved in the direction of arrow t. Therefore, the shutter 26
The card 8 exiting is conveyed while being held by the conveying roller 3 and the pad roller 7, and at the same time, the heads 9 and 9 fixed to an arbitrary frame between the distances n exchange information signals with the card. Be seen.

FIG. 2 shows the essential parts of an embodiment of the card carrier of the present invention. 2A is a cross-sectional view seen from the card passage direction, and FIG. 2B is a side view seen from the arrow A, A ′ direction of FIG. 2A.

In the figure, 10 is a drive source such as a motor, through which a drive shaft 11 for transmitting the power of the drive source is inserted through bearings 12, 12. Reference numeral 13 denotes a moving unit that constitutes a card transport unit, and the moving unit includes a shaft 4 and a shaft 5.
A shaft 6 is rotatably supported, and a G ₁ roller 1 serving as a moving roller, a G ′ roller 2 serving as an intermediate roller, and a G ₀ roller 3 serving as a card conveying roller are fixed to each of the shafts. Has been done. The moving unit is provided with moving holes 14, 14 in the card advancing direction, and movably holds a slide shaft 15 fixed to a frame 16 serving as a fixed portion,
It can be moved in the direction of the card passage. Reference numeral 17 is a putt spring that applies a biasing force to the putt roller 7 that holds the card.

The head 9 comes into contact with the card 8 to read the input information recorded in the stripe, or to record the information in the stripe, and is fixed to the frame 16 so that the stripe can be recorded. They are arranged opposite to each other through the card passage.

The drive source 10 is rotated as shown by the arrow in FIG. 2B when the card is taken in, and is rotated in the reverse direction when the card 9 is read or recorded by the head 9. Not controlled by the control means.

In FIG. 2, the drive source 10 to the drive shaft 11
When the G ′ roller 2 is driven via the G ′ roller 2, the G ₁ roller 1 and the G ₀ roller 3 whose outer circumference is in contact with the G ′ roller 2 are rim-driven to rotate in the arrow direction. In the above description, each drive has shown the configuration of rim drive, but when the gears are fixed to the shaft 4, the shaft 5 and the shaft 6, respectively, and when the shaft 5 is driven by the meshing of the gears, the shaft 4 and the shaft 5 rotate. Alternatively, the respective rollers may be driven accordingly.

As shown in FIG. 3, transmission of the driving force from the driving source 10 such as a motor to the moving unit 13 can be performed by fixing the driving source 10 to the moving unit 13 itself to be a direct drive. A drive source can be placed on the fixed part as shown in FIG. FIG. 4A is a side view showing the relationship between the drive source and the moving unit, and FIG. 4B is a sectional view seen from the direction perpendicular to the plane of the drawing.

In the figure, the drive source 10 is fixedly placed on a frame 16-1 which is a fixed portion, and is installed on a pulley 19 attached to the end of the drive shaft 11-1 of the moving unit 13-1 with a belt 18. Has been done. Mobile unit 13-1
From the above, tension rollers 20 and 20 are provided in a protruding manner to apply tension to the belt. When the drive source 10 is driven in this state, the pulley 19 rotates via the belt 18, so that the moving unit 13-1 can be driven in the same manner as shown in FIG.

With this configuration, when the drive source 10 rotates upon receiving a trigger signal indicating that a card has been inserted through the card insertion slot, the G ₁ roller 1 and the G ₀ roller 3
Rotate in the same direction. Since the moving unit 13 provided with these rollers is movable with respect to the frame 16 with the slide shaft 15, when the outer peripheral portion of the G ₁ roller 1 contacts the frame 16, the moving unit 13 moves in the card passage direction with the contact point P. On the other hand, since the G ₀ roller 3 is also rotating in the same direction, the card is held between the pad roller 7 and conveyed. As described above, when a driving force is applied to the G'roller 2, the card transport unit itself moves and the transport roller rotates, so that the card can be transported. The card sandwiched between the driving roller and the driven roller in this manner is conveyed to the far end of the card passage, and information signals are transferred to and from the card during that time.

Although the driving force is applied to the G'roller 2 in the above description, it may be applied not only to the G'roller 2 but also to the G ₀ roller 3 and the G ₁ roller 1.

When the G ₁ roller 1 is rotated, the outer periphery of the roller is S ₀ = πφD ₀ × V _0, and the frame serving as the fixed portion is moved S ₀ . Here, D _{2 is the} diameter of the rubber roller V _{0 is the} number of rotations of the rubber roller. Therefore, the amount of movement per one rotation of the rubber roller is S = πφD ₀ . Since the amount of movement of the card is the sum of the amount of movement S ₁ of the G ₀ roller 3 and the amount of movement S ₀ of the G ₁ roller 1 relative to the fixed portion, the card is 2 times the moving speed of the roller relative to the fixed portion.
Move in double. In other words, it is possible to convey the fixed portion a distance twice as long as the conventional roller conveyance in the same time.

If the head 6 is attached to the frame 16 which is the fixed portion, the card passes over the head 6 at a speed twice that of the conventional roller conveyance. Moreover, since the moving speed of the card itself with respect to the roller is the same as that of the conventional structure, the card can pass over the head 6 without being displaced or displaced from the roller.

In the above, the transport unit drive roller G
_In FIG. ₁ , a rubber roller is used in the figure, but a pinion gear can be used if the fixing part is a rack.

Even if one rubber roller slips, the amount corresponding to the moving amount of the other rubber roller is not increased by the driving of the moving roller with respect to the fixed portion and the driving of the card with respect to the driving of the card conveying roller. Since the card moves, jams are less likely to occur. Further, even if one rubber roller slips, the amount corresponding to the moving amount of the other rubber roller is always returned to the hand, so that the jam can be taken out easily. With such a configuration, the pad roller gap mechanism for delivering and receiving the card, which is considered in the mechanism of the conventional example, is unnecessary. In addition, there is no loss of driving force when the card is delivered. Since only one rubber roller is required to transmit the torque, not only the number of parts of the drive system can be reduced, but also the delivery roller need only be supported, so that the number of parts can be reduced also from this aspect.

[0031]

In the card carrying device of the present invention, a moving unit composed of a card carrying roller, an intermediate roller and a moving roller is integrally formed, and a driving force is applied to any of the above rollers to rotate the respective rollers. Moreover, since the moving roller is moved with respect to the fixed portion, and the card is carried by the card carrying roller and the pad roller, the card is carried by three roller pairs like the conventional card carrying section. There is no need to hand over. As a result, it is possible to prevent the occurrence of jams and slips during transportation. Moreover, since the card transport section is formed with a simple structure, it is highly economical.

Since the head is attached to the fixed portion and the card conveying roller conveys the fixed portion and the moving roller conveys the card, the card passes over the head at a speed twice that of the conventional roller conveying. For this reason, the exchange of information signals with the card becomes faster. Moreover, since the moving speed of the card itself with respect to the roller is the same as that of the conventional configuration, the card does not come off the roller or is not displaced, and the card stripe surely passes over the head, thus ensuring the reliability of the card information. improves.

While the head is provided at an arbitrary position of the fixed portion across the card passage, a distance n corresponding to the length of the card is provided in the fixed portion as a moving distance of the moving unit, so that the entire length of the card is extended. Information can be exchanged even if the information is recorded in. Therefore,
The degree of freedom of the position where the head is provided can be increased.
