Description

[Detailed Description of the Invention] [Industrial Technical Field] The present invention provides a card that has a function to take in a second card, has a simple structure, can be made thinner, and can prevent forgetting of the card. It relates to a processing device.

[Conventional technology]

Among various devices that provide services using cards, a magnetic card public telephone is a typical example of a device that has a card insertion slot and a card return slot. First, we will discuss the necessity of two card slots and the configuration of a conventional card processing device for magnetic card public telephones.

The magnetic card used in this telephone initially stores the number of call possibilities corresponding to the purchase price. When a user inserts this card into a telephone, the telephone reads the information on the card's callable power, and if there is a callable power, this number is displayed on the display on the telephone panel and a call is permitted. When a call begins, the exchange issues a billing signal for each unit of time. Each time the telephone receives this signal, it subtracts the number of possible calls. When the user goes on-hook, the call is disconnected, the number of possible calls is rewritten on the card, and the card is returned to the user. On the other hand, when the number of available calls reaches zero during a call, the used card is returned to the user or stored in the phone.
The call will be forcibly disconnected at the next billing signal. Therefore, if you want to continue talking even after the number of available calls reaches zero, you must insert the next card with remaining available number of calls before the next billing signal arrives. However, the interval between billing signals varies depending on the time of day the phone is used and the distance to the other party.
The shortest time is a few seconds, so if there is only one card slot, the next card must be inserted within this short time, resulting in extremely poor service. Therefore, magnetic card public telephones are equipped with a card insertion slot and a card return slot, and these are connected by a card transport passage, so that even if the previous card is being processed in this transport passage, another card can be stored in the card insertion slot as a backup. It is necessary to be able to insert it as a card.

Figure 1 shows an example of a conventional card processing device, in which 1 is a card insertion slot, 2 is a card return slot, and 3 is a card return slot.
6 is a card taking mechanism which takes in a magnetic card 4 inserted into the card insertion slot 1 and guides it to a card processing conveyance path 5; 6 normally prevents insertion of the magnetic card 4, and is activated by a magnet 7 when the card is taken in; 8 is a card transport mechanism that moves the taken magnetic card 4 along the card processing and transport path 5; 9 is a reader disposed in the card processing and transport path 5; , a card return mechanism 12 for returning the magnetic card 4 punched by the card punch mechanism 11 to the card return slot 2 after the charge settlement process by the writing device 10; This is a switching lever that guides the installed and usable magnetic card 4 toward the card return slot 2 and guides the used card toward the card storage box 13. Further, FIG. 1A shows the card conveyance path of FIG. 1. In the figure, the card conveyance passage 15 is composed of a card take-in passage 16, the card processing conveyance passage, a card return passage 17, and a card storage passage 18, and 19 is a card processing section. The operation of this device will now be described. When the user inserts a card into the card insertion slot 1 and takes the receiver off-hook, the card take-in mechanism 3 and the shutter mechanism 6 are driven by the magnet 7 and change from the state shown by the broken line to the state shown by the solid line. Further, the card transport mechanism 8 is also driven by the drive motor. For this reason,
The magnetic card 4 is taken in by the card taking mechanism 3 and reaches the card processing section 19. At this time, the card take-in mechanism 3 and the shutter mechanism 6 return to their original state as indicated by the broken lines, allowing the insertion of a spare card.
When the reading/writing device 10 reads the call availability number, the call is permitted. During a call, when the user turns on-hook, the number of possible calls on the magnetic card 4 is rewritten by the reading/writing device 10, and a card punching mechanism 11 is inserted into the magnetic card 4 to show this number to the user. A hole is punched and the card is returned through the card return slot 2.
Furthermore, during a call, when the number of possible calls becomes zero, the card taking mechanism 3, shutter mechanism 6, and card transport mechanism 8 are driven again, so the spare card is drawn into the card processing section 19, and accordingly, Used cards are returned or stored. This switching is performed by a switching lever 1 driven by a solenoid 20.
This is done by 2. As described above, although the conventional card processing device satisfies the basic functions necessary for a magnetic card public telephone, it has the following problems.

First of all, it is desired that magnetic card public telephones be made smaller. In addition, there is a strong demand for card communication terminals such as magnetic card facsimiles to be smaller, thinner, and more flexible in design. However, in the conventional card processing apparatus, as shown in FIG. 1A, the conveyance path 15 is long and vertical, so it is difficult to satisfy these requirements.

In the conventional device, the card insertion slot 1 and the card return slot 2 are provided at a considerable distance, so the user tends to forget the returned magnetic card, resulting in poor service quality. It is desirable that the structure be such that returned magnetic cards are visible.

Since there is not a sufficient mechanism to prevent fraudulent cards such as folded cards from entering, the transport device is required to have a large transport force in order to guide such cards to the return slot. This makes the mechanism complicated, large, and expensive.

The conventional second sheet take-in mechanism is designed with a long transport path and therefore a large mechanical space, and lacks consideration for miniaturization, especially thinness.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and has a mechanism for taking in a second card, and by providing a card insertion slot and a card return slot in close proximity, it is possible to reduce the thickness of the card. Another object of the present invention is to provide a card processing device that allows card insertion and removal at approximately the same position and prevents forgetting the card.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

First, FIG. 2 shows the basic configuration of the present invention. In the figure, S1 is an insertion detection element consisting of a light emitting element and a light receiving element, S2 is a return detection element also consisting of a light emitting element and a light receiving element, 25 is a card pressing mechanism as a card taking mechanism, and P is a card punch. R is a card reading device, W is a card writing device, and although the card transport mechanism and card return mechanism are not shown, they are assumed to be arranged in the same way as the conventional device shown in FIG. Further, the card insertion slot 1 and the card return slot 2 are provided close to each other vertically. The back ends of the card waiting passage 16 and the card return passage 17 are adjacent to one end of the card processing passage 5. One end of the card return passage 17 communicates with the card return slot 2, and the other end can be connected to one end of the card processing passage 5 at the far end position of the card waiting passage 16, and together with the card processing passage 5, card processing and return are possible. forming a passage. The magnetic card 4 has flexibility and elasticity. Shock mechanism 6
is provided near the end of the card standby passage 6 to enable insertion of a second card from the card insertion slot 1. Note that the thighs with the same reference numerals as in FIG. 1 have the same structure, and the explanation thereof will be omitted.

3 and 4 are control circuits and operation timing diagrams of the card processing device having the configuration shown in FIG. 2. FIG.

A series of operations of the card processing device will be briefly explained based on these figures. When the user inserts the magnetic card 4 from the card insertion slot 1, the magnetic card 4 is stopped from entering at a certain length by the shutter mechanism 6. Next, when the card pressing mechanism 25 moves downward in the direction of the arrow in response to a command from the microprocessor 30, the leading end of the magnetic card 4 is bent into the card waiting passage 16 due to its flexibility. . Next, when the card transport mechanism takes in the magnetic card 4, the magnetic card 4 is elastic, so it restores its original shape and is guided to the card processing path 5. The card pressing mechanism 25 is restored after the magnetic card 4 is taken in, and when the card pressing mechanism 25 is restored, the card standby passage 16 becomes empty, so that a spare card can be inserted. The card processing passage 5 is moved from the card waiting passage 16 by the card transport mechanism.
The serviceability number of the magnetic card 4 transported to the card processing unit 19 is read by the reader R and stored in the memory 31 of the microprocessor 30.
is memorized. If there is a service availability number, first the number in the memory 31 is reduced by one number (corresponding to the charge being preempted by one number).
Service is started. When the service time corresponding to one degree has elapsed, the number of degrees is decremented again and the service is continued. If a spare card (second card) is inserted during the service, S1
is detected and the memory 31 stores this state. As the service progresses, the power decreases to 0, and the card writing device W writes the power 0 to the magnetic card.After a punch indicating that there is no power remaining, the card is transferred to the card transport mechanism. The card is then transported to the card return path 17 and returned from the card return slot 2 by a card return mechanism (not shown).
When the return operation is completed, the return detection element S2 detects this. If a spare card is not inserted into card slot 1, the service will be forcibly disconnected when the last service time has elapsed, but if a spare card is inserted, The card pressing mechanism 25, the card transport mechanism, and the transport device perform the card loading operation again, so that the service is continued. Note that the transport mechanism drive motor, card punch device, etc. shown in FIG.
controlled by

FIG. 5 shows another embodiment in which the card waiting passage 16 and the card processing passage 5 are set at almost the same height, the card pressing mechanism of FIG. 3 is removed, and the card waiting passage 16 and the card processing passage 5 are The only difference from the above embodiment is that a switching lever 12 is provided in the branch channel of the card return channel 17. The operating timing in this case is shown in Figure 4 for the shutter mechanism 6 and the switching lever 1.
Since it is sufficient to add the second operation, it will be omitted. The inserted magnetic card 4 is first stopped by the shutter device 6. When the loading operation is started in response to a command from the microprocessor, the shutter mechanism 6 moves upward as shown by the dashed line and enters the card waiting path 1.
Open 6. Next, the leading end of the magnetic card 4 is taken into the card processing path 5 by the card taking mechanism. At this time, the switching lever 12 rotates downward as shown by the broken line, and the card processing path 5 is opened. When the end (left end in the figure) of the magnetic card 4 passes through the shutter mechanism 6, the shutter mechanism 6 and the switching lever 12 are restored as shown by the solid line again. With this operation, communication between the card waiting passage 16 and the card processing passage 5 is cut off by the shutter mechanism 6.
A spare card can be inserted. After the call ends,
When the magnetic card 4 is moved in the opposite direction through the card processing path 5, its tip (left end) is bent downward by the switching lever 12, guided into the card return path 17, and returned from the card return slot 2.

FIG. 6 is an embodiment that combines the embodiments of FIGS. 2 and 5. The inserted magnetic card 4 is bent upward by the card pressing mechanism 25 and taken into the card processing passage 5. The processed magnetic card 4 is moved in the opposite direction within the card processing path 5, guided into the card return path 17 by the switching lever 12, and returned from the card return slot 2.

Next, specific structural examples of each component, mechanism, etc. of the card processing device according to the present invention will be described in detail based on FIGS. 7 to 66.

FIG. 7 shows an embodiment of the present invention, in which 1 is a card insertion slot, 2 is a card return slot provided close to the card insertion slot 1, and the section from 1 to 62 indicated by 16 is the card insertion slot 1. In the card waiting passageway, one end of which is connected to the card, there is a gap at least equal to the thickness of the card, and the structure is such that the card can be placed on standby. Rollers 54, 41, 65, 4 from card return path 2
The passage on the belt 44 wrapped around the
Among the return passages, the section from the card return passage 2 to the belt of the roller 41, ie, the section indicated by 51, is the card return passage, and the section on the belt 40, ie, the section indicated by 5, is the card processing passage. Card processing/
A on the return path corresponds to the section from rollers 41 to 65 on the belt. The rollers 41 and 47 are card take-in roller mechanisms provided above and below the card standby path so as to face each other with a gap at least equal to the thickness of the card.

6 is a shutter mechanism provided near the end of the card waiting path 16.

The motorized roller 42, the rollers 56, 65, the belt 44 connecting them, and the roller/belt mechanism of the rollers 55, 45 opposing these are card transport mechanisms for moving cards along the card processing/return path. be.

Further, the motorized roller 42 and the belt 44 are also a driving force transmission mechanism for transmitting a part of the driving force of the card transport mechanism to the roller 41 provided at the lower part of the card waiting passage 16. That is, in this embodiment, the card transport mechanism also functions as a driving force transmission mechanism.

Reference numeral 48 denotes a roller pressing drive mechanism for changing the card standby path 16 into a card receiving path by pressing the roller 47 that is not being driven against the roller 41 that is being driven. The pressing drive mechanism is driven and controlled after confirming that no card is present in the card processing path 5. Furthermore, 57
A, 57B is a read/write magnetic head, 58
A and 58B are card punch mechanisms, 59 and 60 are photocouplers, 61 is a light source, 62 is a light shielding length detection sensor, 63 is a piezoelectric element whose electrical characteristics change when pressurized, and 64 is a shutter to prevent reverse card insertion. be. Note that the roller 65 may be omitted. Furthermore, since the card take-in roller 41 and the rotational force unidirectional transmission mechanism 52 are shown overlapping each other, FIG.
The three-dimensional configuration is shown in detail in b.

FIG. 7 and FIGS. 9 to 11 show in detail the changes in the state of the magnetic card with respect to the operation of this device. I will explain step by step. FIG. 7 shows the state in which the magnetic card 4 is inserted. The magnetic card 4 is inserted into a card waiting path 1 formed by card insertion support mechanisms 49A, 49B and a card support plate 50.
6 until it is stopped by the shaft mechanism 6. When taking in a card, the magnetic card 4 is pushed onto the card taking part of the belt 44 which is wrapped around the card taking roller 41 by a card pushing roller 47 driven by a roller pushing drive mechanism 48. It will be done. Here rollers 42, 41, 6
5 rotates and moves the belt surface in the card-taking direction, the magnetic card 4 is taken into the card processing path 5 along the card waiting path 16. After taking in the magnetic card 4, the roller pressing drive mechanism 48 is restored. The situation at this time is shown in FIG. Since the card standby passage 16 becomes empty, a spare card can be inserted. The magnetic card 4 is moved back and forth within the card processing path 5, and processes such as reading, writing, and punching are performed. Note that FIG. 12 shows a magnetic card with a punch hole 73 punched therein. After the predetermined processing, if the magnetic card 4 is to be stored in the card processing device as it is, it is moved to the right. When returning the card, the card is moved in the opposite direction and guided to the card return path 17. This situation is shown in FIG. Regarding the operation of the card return mechanism 51, please refer to Section 8.
This will be explained using figures. In the figure, 70 is a wheel with pawls 71, which rotates left and right in conjunction with the movement of the rollers 41. However, as is clear from the figure, this pawl 71 transmits rotational force to the wheel 70 only when it rotates in the counter-intake direction, that is, to the left. Therefore, only when the belt 44 moves in the card receiving direction,
The belt 56 moves in the opposite direction, and the magnetic card 4
is transported to the card return slot 2. After the magnetic card 4 has been conveyed to the card return slot 2, the device may move on to the operation of taking in the spare card 4' (Fig. 11), but the above operation may cause the device to move to the card taking part A (Fig. 7). )
is in an empty state, and even if the roller 41 rotates in the take-in direction, that is, in the right direction, the return card 4'' (FIG. 11) will not return due to the rotational force one-way mechanism 52. It is possible to take in the spare card 4' without being obstructed by the card 4''.

FIG. 13 shows another embodiment of the card return mechanism. The difference from FIGS. 7 and 8 is that the rotational force unidirectional transmission mechanism 52 has a smaller diameter than the roller 41. In FIG. 8, since the diameters are the same, the diameter of the rotational force unidirectional transmission mechanism 52 of the magnetic card 4 is smaller than that of the roller 41 when the card is taken in. In Figure 8, since the diameters are the same, when loading the card,
The magnetic card 4 is conveyed while sliding on the belt surface on the rotational force unidirectional transmission mechanism 52. At this time, since a frictional force is generated, the roller 42 requires a correspondingly large driving force. On the other hand, in FIG. 13, this problem is solved by making the rotational force unidirectional transmission mechanism 52 smaller than the roller 41. In order to make the conveyance speed of the roller 41 and the roller 54 the same when returning, a small wheel 54A that interlocks with the roller 54 is provided, and the rollers 54 and 54A are connected by a belt 56.

FIG. 14 shows yet another embodiment of the card return mechanism. FIG. 15 is a three-dimensional view of this. In these figures, 77 is a wheel that rotates in conjunction with the roller 41, and 78 is a tension control mechanism that is normally in the restored state and applies tension to the belt 56 as necessary. When guiding the magnetic card to the return slot 2, the tension control mechanism 78 is driven to apply tension to the belt 56 and rotate the roller 54. On the other hand, when taking in a magnetic card, the tension control mechanism 78 is restored and the belt 5
6 in the direction of loosening (direction of arrow B in FIG. 15) so that no conveying force is generated. The purpose of this mechanism is the same as that of the card return mechanism 51 shown in FIG.

FIG. 16 shows another embodiment of the card taking mechanism. In the figure, reference numeral 80 denotes a lever mechanism with C as a fulcrum, which is located behind or in front of the card processing and conveyance mechanism 45. The operating principle will be clear from the diagram. By using this lever mechanism 80, the present device can be made even thinner. That is, as point C approaches the roller pressing drive mechanism 48, the amount of displacement of the movable element 81 required to move the card pressing roller 47 a predetermined distance becomes smaller when directly driven as shown in FIG. It takes less than that. Therefore, the roller drive mechanism 48 can be designed to be small and consume less power. In the above embodiments, the roller drive mechanism 48 may be an electromagnet, or a mechanism using a piezoelectric element that generates force and displaces when a voltage is applied. Further, a rotary motor is suitable for driving the driving force transmission roller 42 (see FIG. 7).

Next, the function of the card reverse insertion prevention shutter 64 will be described. When the card insertion slot 1 and the card return slot 2 are arranged side by side as in the embodiment shown in FIG.
The user may try to insert the magnetic card 4 through the card return slot 2. Of course, as shown in the figure, the card insertion slot 1 has an expanded shape that makes it easy to insert the magnetic card 4 by cutting the edges, etc., and the card return slot 2 has a shape that makes it difficult to insert it, and the usage instructions are displayed on the panel surface 85. Although it is possible to reduce the number of mistakes by doing so, there are still cases where mistakes are made or insertions are made intentionally. Therefore, a mechanism is required that prevents the insertion of magnetic cards from the card return slot 2. The card reverse insertion prevention shutter 6
4 is attached to the card insertion support mechanism 49B, and when the tip is pushed with the magnetic card 4 from the right, it rotates to the left and opens the card return passage 17. After the magnetic card 4 has passed, the stopper 86 is closed by the spring force. The mechanism is such that it returns to its original position and does not rotate to the right from this position. This mechanism prevents insertion of the magnetic card 4 from the card return slot 2.

Next, we will discuss countermeasures against fraudulent cards. The purpose of the present invention is to shorten the card conveyance path, use inexpensive parts, and reduce the conveyance force. It is preferable to detect this before all the magnetic cards 4 are taken in or at least into the card processing path 5, and to eliminate this by applying a reverse conveyance force to the card waiting path 16. The method for detecting and removing fraudulent cards will be described below.

(a) Technique for detecting a card with incorrect dimensions In FIG. 7, photocouplers 59 and 60 are paired and placed across the length of the card.
As shown in FIG. 9, if the photocoupler 60 detects the tip of the magnetic card 4 at the time when the photocoupler 59 detects the end of the magnetic card 4, the length of the magnetic card 4 is determined to be correct; otherwise, it is considered a fraudulent card. Process. As the photocouplers 59 and 60, photocouplers each consisting of an LED and a phototransistor are inexpensive and suitable, but an image sensor may be used instead of the phototransistor. For example, when an image sensor is used to detect the leading edge of a magnetic card, after measuring the length of the magnetic card 4 in combination with the photocoupler 59 as described above,
It is also possible to detect the size of the punch holes 73 (FIG. 12) and the spacing between the holes when the card is taken into the card processing passage 5, which is even more effective in detecting fraudulent cards. This embodiment is shown in FIG. 12, where 60A is an image sensor. Although not shown in the figure, a light source is installed on the surface of the magnetic card 4 facing the image sensor 60A. When the magnetic card 4 passes through the image sensor 60A, the punch hole 7
The position, shape, and spacing of 3 can be detected.
The interval can be determined by converting the distance that the magnetic card 4 travels from the first punch hole to the next punch hole from the rotational speed of the motor. The length of the magnetic card 4 can also be measured by placing the photocoupler 60 further to the left in FIG. 9, for example at point D. To do this, after the tip of the magnetic card 4 passes the photocoupler at the D point position, the photocoupler 5
The distance that the magnetic card 4 travels until 9 detects the end of the magnetic card 4 is determined by converting it from the detection of the rotational speed of the motor, etc., and the value obtained by adding this distance (length) to the spacing between the photocouplers is, It is sufficient to detect whether the length matches the length of the correct magnetic card.

(b) Technology for detecting cards with incorrect shapes Folded cards are the most important card with incorrect shapes for transportation. Therefore, we will discuss the detection of cards that have been plastically deformed due to bending.

FIG. 17 shows an example using an optical system. A light source 61 attached to the tip of the card insertion support mechanism 49A illuminates the light receiving surface of the shading length detection sensor 62. The magnetic card 4 is inserted along the card standby path 16, and when it reaches the sensor 62, the lower part of its light-receiving surface is shielded from light. Therefore, a deformed card can be detected by measuring this light-shielding length l using the sensor 62 and comparing whether this value is within the permissible range. In this case, when the magnetic card 4 is deformed upward, the light-shielding length l becomes longer than when the magnetic card 4 is a normal card, and when it is deformed downward, it becomes shorter. An LED can be used as the light source 61, and a phototransistor, an image sensor, etc. can be used as the light shielding length detection sensor 62.

FIG. 18 shows an embodiment using a pressure detection element. The pressure detection element 63 is mounted on the tip of the card support plate 50. Since the card support plate 50 has elasticity, pressure is applied to the pressure detection element 63 when the magnetic card 4 is taken in. It is possible to detect a deformed card by sequentially detecting the magnitude of this pressure while the magnetic card 4 is being conveyed and comparing the output pattern with that of a correct card. In the case of a deformed card whose tip is bent in the shape of a square as shown by the chain line 89, the pressure is smaller than in the case of a correct magnetic card. Note that the pressure detection element 63 may be installed at a location where the pressure of the magnetic card 4 can be detected while the magnetic card 4 is being transported, and may be, for example, the position of point E.

(c) Unauthorized card removal method FIG. 19 shows a method in which, when an abnormality in the shape or size of a magnetic card is detected, the card transport mechanism 40 is driven in the opposite direction, that is, the return direction, and the card is removed from the card insertion slot 1. The figure shows how long cards are eliminated.

FIG. 20 shows a method for removing from the card return slot 2 an unauthorized card that has entered the card processing passage 5 for some reason. The card transport mechanism 40 is used as in the case of a correct card, but if this mechanism alone does not have sufficient transport force, the roller pressing drive mechanism 48 of the card taking mechanism 46 is driven as shown in the figure to move the card pressing roller. 47 may be pressed against the card to increase the return conveyance force. As another method of removal, the fraudulent card may be moved to the right side of the card processing passage 5 as indicated by the broken line in FIG. 20 and removed into the card storage box 13.

FIG. 21 shows another embodiment of the present invention. 22nd
The figure shows a three-dimensional configuration diagram. In comparison with FIG.
The difference is that the interval between them is widened in order to distinguish them from the card return slot 2 and the card return slot 2. In the figure, the card support plate 50 is attached to the card insertion support mechanism 49B so that the tip thereof faces slightly upward, and 90 is a spring mechanism for pushing the roller 55 in the direction of the roller 54. FIG. 21 shows how the card is returned with the spare card 4' inserted. Also the second
Figure 3 shows how the card is loaded. The effect of making the card support plate 50 face upward and elongated will be described. The card support plate 50 attached to the card insertion support mechanism 49B not only supports the bottom surface of the inserted magnetic card 4, but also has the function of guiding the return card 4'' to the card return passage 17. The latter function becomes greater as the length increases.If the guide functions sufficiently, the return card 4'' will not accidentally enter the card waiting passage 16, so the lower surface of the inserted card and the card handling passage 5 It is possible to shorten the distance to the closing part A. As a result, the moving distance of the card pressing roller 47 can be reduced, and the pressing roller drive mechanism 48 can be small and inexpensive.

FIG. 24 shows a fraudulent card detection section. Although the card support plate 50 is facing upward,
The principle is the same as that shown in FIGS. 17 and 18.
Note that by preventing bent cards from entering, the load on the transport mechanism can be reduced and the strength can be reduced.

FIG. 25 shows the card support plate 5 in FIG. 21.
This is an embodiment in which the card standby passage 16 and the card processing passage 5 are placed on the same plane by further oriented upward.

FIG. 26 shows still another embodiment of the present invention.
In the present invention, a card insertion slot 1 and a card return slot 2 are essential. Therefore, it is important to ensure that the user does not mix up these cards and to make sure that the returned card is visible to the user. This embodiment is for this purpose. In the figure, F is the user's eye, P1 is the card insertion surface, P2 is the card return surface, 64 is a card reverse insertion prevention shutter that rotates around point G, 92 is a return guide plate forming the card return surface, 93 is a spring mechanism that presses the shutter 64 against the return surface of the return guide plate 92. Further, 94 may be omitted with a return port cover.
The magnetic card 4 is placed in a downwardly curved card return path 17.
The card is transported to the card return slot 2 along the route. At this time, the reverse card insertion prevention shutter 64 and the return slot cover 94 are pushed open by the tip of the magnetic card 4, so that the magnetic card 4 becomes as shown in FIG. 27 at the end of the return operation. In this embodiment, the card return slot 2 is located further back than the panel surface 85, so that it is not normally visible to the user. Therefore, card return slot 2
Misuse of the card slot 1 and the card insertion slot 1 can be prevented.
Further, although a pattern is normally drawn on the top surface of the magnetic card 4, in this embodiment, since P2 has an appropriate angle θ with respect to P1, this pattern is easily seen, and therefore the return card You can prevent forgetting to take it. Incidentally, FIG. 27 shows how the spare card 4' is taken in after the card is returned.

FIG. 28 shows another embodiment of the present invention. In the figure, 95 is a return card storage box. In the case of magnetic card public telephones, a number of cards with few remaining callable points may be used. In this case, used cards are returned one after another from the card return slot 2. In this embodiment, since the return card 4'' is accumulated in the return card storage box 95,
The user can make a call without worrying about the return card 4''.

FIG. 29 shows another embodiment of the shifter mechanism. In the same figure, reference numeral 97 denotes a shutter that rotates about point H as a fulcrum by the roller pressing drive mechanism 48;
is a pawl that rotates when pushed from the right as shown in Figures 30a and b. The shutter 97 is normally in the state shown by the broken line in FIG. 29, and the inserted magnetic card 4 is stopped by the pawl 98. When taking in a card, when the card pressing roller 47 is driven by the pressing roller drive mechanism 48, the shutter 97 moves as shown by the solid line in conjunction with this and moves into the card processing path 5.
open. Also, when returning the card, the claw 98 is the third
It rotates to the right as shown in Figure b, allowing the magnetic card 4 to pass and be returned.

FIG. 31 shows another embodiment of the shutter mechanism.
Figure 32 shows the three-dimensional structure. In these figures, the shutter 99 is rotated in the vertical direction about a point by the roller pressing suspension mechanism 48, and 100 is a stop plate attached to the shutter 99. When loading, the roller pressing drive mechanism 4
When the card pressing roller 47 is pressed down by the shutter 8, the shutter 99 rotates clockwise in conjunction with this, and releases the restraint on the magnetic card 4. This situation is shown in FIG. After the magnetic card 4 is taken into the card processing path 5, the shutter 99 is restored in conjunction with the restoration operation of the roller pressing drive mechanism 48.

FIG. 34 shows another embodiment of the present invention in which the card processing passage 5 is vertical. In the figure, reference numeral 101 is a roller provided opposite the card taking-in roller 41, but it may be omitted. Further, the belt mechanism for driving the roller 54 may have a small diameter as in the embodiment shown in FIG. 13. In this embodiment, the seventh
Since it is the same as the figure, the explanation of the operation will be omitted.

FIGS. 35a and 35b show still another embodiment of the present invention. The card return mechanism is different from the embodiments shown in FIGS. 7, 21, 26, and 34. Only the different points will be explained. In the same figure, 11
0 indicates rollers 54 and 55, a roller 111 that rotates in conjunction with the card take-in roller 41, and a belt 56 that transmits the rotation of the roller 111 to the roller 54.
112 is a card separation lever that separates the magnetic card 4 from the rollers 54 and 55 when returning the card; 113 is the lever 112;
114 is a stopper that prevents the lever 112 from rotating beyond a certain level; 115 and 116 are magnetic card 4;
This is a return port guide that guides the user to the card return port 2. FIG. 36 shows an enlarged view of the vicinity of the card return slot. Third
In Figure 5, the magnetic card 4 is connected to the card return mechanism 11.
0, the card is moved through the card return path 17, but the card conveying force is due to the fact that the right end of the magnetic card 4 is moved by the roller 54,
It disappears when it passes through the two-dot chain line DT1 connecting each of the rotation axes of 56. Here, if the card retrieval mechanism starts retrieving the spare card, the card return mechanism 110 is driven in the direction opposite to the card return direction, so there is a risk that the magnetic card 4 that should have been returned may enter the card return path 17 again. be. Therefore, the card separation lever 12 is provided to separate the magnetic card 4 by a certain distance when the right end of the magnetic card passes the two-dot chain line DT1, and to prevent reverse insertion. Third about the function of the card separation lever 112
This will be explained using FIGS. 6 to 38. FIG. 36 shows that the returned magnetic card 4 is attached to the card separation lever 112.
This shows how to press the J side. Since the card separation lever 112 rotates clockwise about point K as a fulcrum against the force of the spring 113, the card return passage 17 is opened and the magnetic card 4 is moved to the return slot guides 115, 111 as shown in FIG. Proceed to. When the right end of the magnetic card 4 passes through the L portion of the card separation lever 112, the card separation lever 112 attempts to recover due to the spring force. At this time, the M side of the card separation lever 112 moves the magnetic card 4 from the card return path 17 to the return slot guide 1 as shown in FIG.
In order to extrude to 15, 116, the double-dashed line DT
1, a distance ΔX1 (FIG. 36) occurs. The state of the magnetic card 4 at this time is shown by the dashed line in FIG. 36. At the end of the push-out operation, the J surface of the card separation lever 112 blocks the card return path 17, so that reverse insertion of the magnetic card 4 is prevented.

FIG. 39 shows another embodiment of the card separating mechanism. In this embodiment, the return guide 1 is separated from the card return passage 17 by at least the thickness of one card.
It is characterized by the provision of 15 and 116 passages 118. When the right end of the magnetic card 4 passes the two-dot chain line DT1, the magnetic card 4 deforms as shown in FIG. 40 and pushes the roller 54 in the direction F1 due to its elastic force. At this time, a force F3 acts on the magnetic card 4 in the return direction as a reaction from the roller 54, so that the magnetic card 4 is pushed toward the card return slot. The separation distance when the card separation operation is completed is shown in FIG. 39 ΔX2. In FIG. 39, the card separation lever 112 is also used to enhance the separation effect, but the M-plane function of the lever 112 may be omitted. In addition, in this embodiment, the return port guides 115, 116
A separate shutter for preventing reverse card insertion may be provided.

As described above, in this embodiment based on the structure shown in FIG. 7, the card passage is Y-shaped, that is, the upper part of the bifurcation forms the card waiting passage 16, and the lower part forms the card return passage 17. Further, the portion where the two forks are closed constitutes a card processing passage 5. Card waiting aisle 1
6 is converted into a card intake path by a set of roller mechanisms. The card transport mechanism also acts as a driving force transmission mechanism for the rollers. Further, a part of the card return passage (near the belt 41) also serves as a part of the card waiting passage 16. Therefore, the roller 47
Due to the operation of FIG.
It changes into an intake path as shown by the dashed line at the top. In this way, the card waiting passage 16 and the card return passage 17 form an extremely organic connection.
Since these components are used redundantly for each of the loading and returning operations, the number of components can be reduced. Therefore, it is suitable for miniaturization.

Further, the gap between the card standby passages 16 is usually larger than the thickness of the card, and since the shutter 6 is located near the end of the card standby passage 16, the card can be freely inserted up to this position. Therefore, the user can have the second card waiting here. Whether or not to import this is determined by checking the remaining power status of the first card and the return processing of the used card.

FIG. 41 shows an embodiment described in claim 2 of the present invention, in which 1 is a card insertion slot, 2 is a card return slot provided adjacent to the card insertion slot, and 1 to 1 are shown as 16. The section up to 6 is a card waiting passage connected at one end to the card insertion slot, and has a gap at least equal to the thickness of the card, so that the card can be placed on standby. The passage from the card return slot 2 on the belt 44 wrapped around the rollers 54, 41, and 42 is the card processing/return passage, and the section from belt 2 to 41 is the card return passage 17, 41 to 42. The section 5 on the belt is the card processing path 5. A on the card processing/return path corresponds to the section from the card blocking portion of the shutter mechanism 6 to the belt 41. roller 4
Reference numerals 7 and 121 designate card take-in roller mechanisms that are provided above and below the card standby path 16 so as to face each other with a gap that is at least the thickness of the card. The shutter mechanism 6 is provided near the end of the card waiting path. rollers 54, 52,
41, a motorized roller 42 and a belt 44 connecting these; furthermore, a roller 55, rollers 122, 123, and a belt 124 provided opposite to this belt are used to move cards along the card processing/return path. This is a card transport mechanism.

The rollers 122, 123 and the belt 124 are also a driving force transmission mechanism for transmitting part of the driving force of the card transport mechanism to the roller 121 provided above the card waiting path 16. That is, in this embodiment, a portion of the card transport mechanism also functions as a driving force transmission mechanism.

Reference numeral 48 denotes a roller pressing drive mechanism for changing the card waiting passage 16 into a card taking passage by pressing the undriven roller 47 against the driven roller 121. The pushing mechanism is driven and controlled after confirming that no card is present in the card processing path 5. The shutter mechanism 6 opens and closes in conjunction with the pressing mechanism 48.

Further, as a modification of the figure, the card taking-in roller mechanism 121 may be a pressing roller, and 47 may be a rotationally driven roller. That is, the driving force of 42 may be transmitted to 47 by a pulley or the like, and the roller 121 may be driven to be pushed down by the roller pressing drive mechanism 48. In this case, the shutter mechanism 6 has the structure 97 in FIG. 29, or the structure 99, 1 in FIG. 31.
00 structure is used.

Here, when the shutter 6 and the pressing roller 47 are moved upward by the pressing roller drive mechanism 48, a conveying force is applied to the magnetic card 4 in the take-in direction, and the restraint by the shutter 6 is also released.
moves along the card waiting path 16. When the tip of the magnetic card 4 pushes the switching lever 12, the lever 1
2 rotates clockwise around the support shaft 130 to open the card processing passage 5. The magnetic card 4 is taken into the card processing path 5 by being further moved to the right. At the point when the card has been taken into the card processing path 5, the roller pressing drive mechanism 48 is restored, and the shutter mechanism 6 and the pressing roller 47 are moved to the fourth position.
Return to the state shown in Figure 1. The switching lever 12 also rotates upward and returns to its original position. Next, the card return operation will be described. When the roller 42 moves in the return direction (counterclockwise), the belts 44, 124, rollers 121, 122, 123, 41, rotational force unidirectional transmission mechanism 52, and roller 54 also move, so
The magnetic card 4 moves along the card return path 17 along the card return trajectory formed by the belt 56, the switching lever 12, and the return path forming plate 126, and reaches the card return slot 2.
will be returned from. Note that the card pressing roller 47 in FIG. 41 may also function as the roller 55. That is, the card pressing roller 47 may normally press the roller 54 to form a card return mechanism, and may move upward as shown in the figure only when the card is taken in.

In such a configuration, as in the above embodiment,
Since the card waiting passage 16 can be changed into a card receiving passage, the configuration is simple, the number of parts can be reduced, the diameter can be reduced, and the second card can be placed on standby. is card return slot 2 near card insertion slot 1.
Since the card is returned face up and at an angle, it is easy for the user to check and there is less chance of forgetting to take it.

FIG. 43 shows another embodiment of the present invention, a specific example in which the system shown in FIG. 2 is realized using a linear motor, and FIG. 44 is a three-dimensional configuration diagram thereof. In these figures,
Reference numeral 140 is a linear motor that is composed of a movable element 141 and a stator 142, and moves the movable element 141 along the stator 142 due to their magnetic interaction. It functions as a card return mechanism. 143 is a movable element drive control device, 144 is a card holding mechanism, 145 is a piezoelectric drive element, 146 is a piezoelectric element drive circuit, and 147A and 147B are magnetic detection elements. 148 is a card transport support mechanism whose card transport surface is on the same plane as the upper surface 0 of the movable member 141, which is not shown in FIG. 43 for simplicity. Note that the other configurations are almost the same as those of the embodiment shown in FIG. 7, and therefore are designated by the same reference numerals. In these figures, a magnetic card 4 inserted from a card insertion slot 1 advances along a card waiting path 16 and is stopped at its leading end by a shutter mechanism 6. When the pressing pin drive mechanism 150 drives the pin 151 to press the magnetic card 4 against the card receiving section A of the card processing path 5, the piezoelectric element drive circuit 1
The movable element 141 controlled by 46 moves to the left and inserts the magnetic card 4 into the card holding groove 152 formed by the upper surface 0 and the piezoelectric drive element 145. Here, when the piezoelectric element drive circuit 146 drives the piezoelectric drive element 145, the magnetic card 4 is held. This situation is shown in FIG. Next, when the pin 151 returns to its original state as shown by the broken line and the movable element 141 is driven to the right, the magnetic card 4 is taken into the card processing path 5. Since the magnetic card 4 that has been taken in is elastic, it returns to its original stretched state. This situation is shown in FIG. As can be seen from the figure, since the card insertion slot 1 is empty, it is possible to insert a spare card 4'. After predetermined processing, the magnetic card 4 is moved by the mover 141.
It is moved to the left end along the card return path 17.
This situation is shown in FIG. When the piezoelectric driving element 145 is restored, the magnetic card 4 is returned from the card return slot 2. In the above operation, the position of the movable element 141 is detected by detecting the magnetic fields of the N and S magnetic poles of the stator 142 using the magnetic detection elements 147A and 147B, and calculating the number of times this magnetic field changes. Note that the magnetic detection elements 147A, 14
A Hall element or the like can be applied to 7B. Further, a card take-in roller 47 as shown in FIG. 7 may be used for the pin 151.

Next, the piezoelectric drive element 1 is attached to the card holding mechanism 144.
The effect of using 45 will be described below. The piezoelectric drive element 145 is an element that generates stress and is displaced when a voltage is applied. Specifically, it is a bimomorph or an element made by laminating and integrating piezoelectric ceramic plates. This piezoelectric drive element 145 is small, easy to reduce weight, is made of cheap materials, and consumes little power.
Since the laminated structure has excellent advantages such as the ability to obtain large stresses, various applications as actuators have been considered in recent years. However, since the amount of displacement is small, there are very few specific examples. The present invention is characterized in that this element is mounted on the movable member 141 of the linear motor 140, and the magnetic card 4 is held by driving the element after the magnetic card 4 is inserted. Since the element is light, even if it is mounted on the movable element 141, the load on the movable element 141 will not become large. Furthermore, the magnetic card 4 can be inserted easily by providing a suitable guide.
The amount of displacement needed to hold the card after it has been inserted may be small. In our study, a thickness of several to 10 μm or more is sufficient. For these reasons, the piezoelectric drive element 145 is suitable for the card holding mechanism 144 of the present invention.

FIGS. 48 and 49 show still other embodiments of the present invention. 155 is a card insertion support mechanism, 1
Reference numeral 56 indicates a shutter mechanism that rotates about P as a fulcrum and applies a restraining force in the clockwise direction; 157 indicates a pin that prevents the shutter mechanism 156 from rotating clockwise beyond a certain level; and 158 rotates about Q as a fulcrum. death,
A switching lever to which a restraining force is applied in the direction of the arrow, 1
59 is a pin that prevents the switching lever 158 from rotating counterclockwise beyond a certain level; 160 is a return trajectory forming plate; and 161 is a pin that prevents the returned magnetic card from going to the right, that is, to the back. The protrusion 162 is a card transport support mechanism that supports the magnetic card 4 so that the magnetic card 4 moves along the card waiting path 16 and the card processing path 5. Note that FIG. 48 shows a state in which the magnetic card 4 is inserted. Other components have substantially the same functions as those in FIGS. 7, 26, and 43, and are therefore designated by the same reference numerals. Further, FIGS. 50 and 51 show a control circuit and operation timing diagram of the card processing device having the above configuration.

To explain the take-in operation, the mover 141
is normally located within the card processing passage 5 and moves within the card intake passage 16 and the card processing passage 5. When the magnetic card 4 is inserted, its leading end is stopped by a shutter mechanism 156. When the movable element 141 is controlled by the movable element drive control device 143 and moves to the left, the shutter mechanism 156 moves the projecting part 1 of the movable element 141, which constitutes a transport path opening mechanism.
65 in the clockwise direction, the card insertion inhibiting function is released. When the mover 141 moves further to the left, the magnetic card 4 moves into the card holding groove 152.
caught in the middle. This state is shown in FIG. Here, when a voltage is applied to the piezoelectric drive element 145 by a drive device (not shown), the element 154
is displaced upward as shown by the broken line in FIG. 53, so the card holding groove 152 is narrowed and the magnetic card 4 is held. If the mover 141 moves to the right in this state,
The tip of the magnetic card 4 rotates the tip of the switching lever 158 clockwise to open the card waiting passage 16, so that the magnetic card 4 is taken into the card processing passage 5. This situation is shown in FIG. When the card loading into the card processing passage 5 is completed, the shutter mechanism 156 and the switching lever 158 are moved to the fourth position.
Since the state returns to the state shown in Figure 8, it becomes possible to insert a spare card. In the card processing path 5, card reading and writing are performed by card reading and writing devices 57A and 57B, and card punching mechanism 58
Punching is performed by A and 58B. Next, the operation of returning the magnetic card will be described. The switching lever 158 is connected to the card waiting passage 16 and the card return passage 1.
Since the magnetic card 4 is located between the magnetic card 4 and the magnetic card 7 and the tip thereof is within the card processing passage 5, the magnetic card 4 moved to the left by the mover 141 is guided to the card return passage 17 by the switching lever 158. This state is shown in FIG. When the card holding by the piezoelectric driving element 145 is released and the movable element 141 is moved to the right, the returned card 4'' becomes like a broken line due to the elastic force, and it becomes possible to take in the spare card 4'. A bimolov type piezoelectric drive element is suitable for the drive element 145 as in the case of FIG. 43, but a piezoelectric drive element of other structure may be used as long as force and displacement can be obtained.

Figures 56a and 56b show another embodiment in which the card return slot 2 is directed downward and a reverse card insertion prevention shutter 64 is provided on the return track forming plate 160 side and biased clockwise by a spring (not shown). .

57a and 57b similarly show the card return opening 2 facing downward and the reverse card insertion prevention shutter 64 being closed.

FIG. 58 shows an embodiment in which the tip of the switching lever 158 is arranged so as to face the card waiting passage 16. The principle is the same as that in FIG. 49, so the explanation will be omitted. 170 is a reverse card insertion prevention shutter 64 connected to the card return passage 17.
It is a spring that presses inside.

FIG. 59 shows an embodiment in which the card holding mechanism is not directly mounted on the movable element of the linear motor, but is moved via a support rod. This is also an embodiment using a piezoelectric driving element having a laminated structure. 171 is a support rod, 172 is a card holding mechanism,
173 is a piezoelectric driving element having a laminated structure, 174 is a holder for the piezoelectric driving element 173, and 175 is a card holding plate. Figure 60 shows the card holding mechanism 172.
The cross-sectional structure of is shown. The magnetic card inserted into the card holding groove 152 is held by the downward movement of the piezoelectric drive element 173. Piezoelectric drive element 1
To operate 73, simply apply a voltage.
The advantage of using a piezoelectric driving element having a laminated structure is that a large force can be obtained, so that the magnetic card 4 can be held securely.

FIG. 61 shows an example of the structure of the piezoelectric driving element 173,
180 is a piezoelectric ceramic plate, 181 is an internal electrode,
182 indicates an external electrode. Since it contracts when a negative voltage is applied and expands when a positive voltage is applied, it is possible to obtain twice the displacement if a negative voltage is applied as a bias. For an element with this shape, the amount of displacement is the voltage
A voltage of about 100V, a voltage of about 100 to 200μm, and a force of several kilograms are possible. The amount of displacement and force required to hold the card are several to 10 μm or more and about 1 kg, respectively, so the element with the above structure can be used satisfactorily.

FIG. 62 shows another embodiment of the card holding mechanism 172. Reference numeral 184 denotes a movable card holding plate that rotates around R as a fulcrum, and its end is attached to the piezoelectric drive element 173. The movable card holding plate 1 185 extends downward when holding the card.
This is a piezoelectric driving element having a laminated and integrated structure for raising the tip of the holder 84 and lowering the tip by contracting when the holding is released.

FIG. 63 is a perspective view showing another embodiment, and FIG. 64 is a side view. In these figures, 190 is a belt, and 191 and 192 are rollers, which are driven by a drive device not shown in the figures. These machines constitute a mover moving mechanism. Further, the card holding mechanism 172 formed by the laminated piezoelectric drive element 173, the card holding plate 175, and the holder 174 constitutes a movable element, and is attached to the belt 190 and moves together. 165 rotates the shutter mechanism 156 clockwise to open the card waiting passage 1.
193 is a return card push-out plate for pushing out the returned magnetic card from the card return slot 2 when taking in a spare card;
195 is a magnetic head, and 195 is a roller mechanism for pressing the magnetic card against the magnetic head 194. The principle of conveyance of the magnetic card is the same as that shown in FIG. 49, so the description thereof will be omitted.

FIG. 65 shows an embodiment in which a movable element moving mechanism using a roller belt mechanism is provided on the return conveyance path side. This figure shows a case where the magnetic card is returned when a spare card is inserted. In the figure, when the card holding mechanism 172 is released and moved to the right, the return card 4'' is moved onto the return track forming plate 160 as shown by the broken line due to elastic force and is returned.Next, the spare card 4' card retention mechanism 172 for capturing
When the return card 4'' is moved to the left, the return card 4'' is pushed out to the left as shown in FIG. 66. Therefore, the return card pushing plate 193 shown in FIG. 63 can be omitted.

It goes without saying that the mechanisms in each of the above embodiments can be applied to each other.

In addition, although the above embodiments have all been described using the magnetic card 4, it is of course possible to use an optical card, and it is said that the use of a linear motor is particularly effective in preventing the influence of magnetic fields. .

〔Effect of the invention〕

As explained above, the card processing device according to the present invention is configured such that the card insertion slot and the card return slot are provided close to each other, and one end of the card waiting passage and the card return passage is located close to one end of the card processing passage. The length of the transport path can be shortened to less than half that of the conventional device, and it can also be made extremely thin and compact, and the volume ratio can be reduced to less than 1/3 compared to the conventional device.
Furthermore, since the card processing path can be bent, there is a large degree of freedom in designing the device, and both horizontal and vertical types can be easily realized. Furthermore, since the card insertion slot and the card return slot can be arranged side by side so that the front and back of the card will not be reversed when returning the card, the card can be returned to a location not far from the position where it was inserted. The card can also be returned by rotating it horizontally relative to the panel surface, and the card does not turn over when returned, making it easier for users to recognize the returned card and improving operability. Sexuality improves.

Furthermore, the present invention reads the information on the card to start the service, and when the information that changes during use no longer satisfies a certain condition, the information on the card is rewritten, the card is returned or stored, and the next step is to card and continue the service. Furthermore, if the service ends before the information no longer satisfies certain conditions, the present invention can be applied to all card-based devices that rewrite the information on the card and return it. Specifically, it is most suitable for card public telephones, television terminals, data terminals, etc. where services are received by paying with a card public facsimile card. When applied to these, the information is the number of available telephone calls or the amount of money equivalent thereto, and it goes without saying that the certain condition is that the number of telephone calls is 1 or more. Further, the card used does not have to be a magnetic card, but may be an optical card, a hologram card, an IC card, etc. as long as it has flexibility and elasticity.

Furthermore, since the present invention allows a second card to be kept on standby during a card-standby call, it is also suitable for systems in which service cannot be received unless a plurality of cards are inserted in succession. As an example, a vending machine can be considered in which a card has the value of a cash voucher and a product is purchased. Further, since the card standby call is changed to a card receiving passage, the number of parts is reduced, and the device can be further downsized. Furthermore, by using this device, even if the amount remaining on the card is less than the price of the desired product, if a second card is inserted in advance, the second card can be inserted and used to purchase the product. Examples of systems include ticket vending machines and time lending machines. Another example would be a system that starts service after inserting two ID cards in succession and verifying each one.
