Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card processing device for receiving an IC card having a memory circuit or the like provided therein and performing a reading / writing process for the IC card.

[0002]

2. Description of the Related Art Unlike a magnetic recording card, an IC card electrically stores various kinds of information in a memory IC and communicates with an external device connected via a terminal provided on an outer surface. It is formed so that information may be transmitted and received by the user.

FIG. 9 shows an example of an IC card 1. A plurality of external terminals 2, 2,..., 2 are provided at a predetermined position near the front end on one surface 1a side of the resin card 1. Each external terminal is connected to a memory IC or the like built in the vicinity of the terminal.

[0004] Unless predetermined information is electrically exchanged via an external terminal, such an IC card cannot know the unique information and the amount information of the card owner. It has the advantage that it is hard to be used illegally and that the contents are not changed by external magnetism, and it has been used instead of a magnetic card.

An IC card processing device for reading / writing information from / to such an IC card does not need to read magnetic information while carrying the card like a magnetic card, and therefore generally has an internal pull-in mechanism. First, the IC card inserted into the card insertion slot is received until at least the external terminal portion thereof enters the inside of the device, the contact terminal is brought into contact with the external terminal of the card in the device, and the information is transferred via the contact terminal. The IC card is configured to be exchanged, and is used by pulling out the read / write processed IC card by hand.

However, in such a system in which the user pulls out the card by himself / herself, it is easy for the user to forget to pull out the card after using the device, and the forgotten card may be illegally used by another person.

In order to solve this, FIG.
Like the IC card processing device 10 shown in (c), it is conceivable that the IC card is automatically ejected from the card insertion slot when the use of the device is finished, prompting the user not to forget the card. .

That is, in this IC card processing device 10,
A bulging portion 12 bulging in the card ejecting direction is provided on a part of the front surface 10a provided with the card insertion opening 11. A solenoid 13 is arranged in the bulging portion 12 and is inserted from the card insertion opening 11. The slide member 16 that is pushed by the tip of the IC card and slides inward and urges the IC card 1 toward the card insertion port 11 by the tension of the spring 15.
Is provided.

Then, the card insertion port 11 of the IC card 1
When the insertion into the card is detected by a sensor or the like, the solenoid 13 is energized to drive the pin 13a out of the card passage, and as shown in FIG. 10 (c), the external terminal becomes a contact terminal in the device. When the IC card 1 reaches the contact position, the energization of the solenoid 13 is stopped and the pin 13a
Is introduced into the card passage by its own weight and brought into contact with the rear end 1b of the IC card 1 to restrict the return of the IC card 1.

Then, when the use of the device is finished, the solenoid 13 is energized to drive the pin 13a out of the passage of the card, and the slide member 16 is returned to the card insertion port 11 by the tension of the spring 15. IC card 1
Is discharged.

Thus, if the IC card is ejected from the card insertion slot 11 after using the device, the user will not forget to remove the IC card.

[0012]

However, in the above-described IC card processing device, the device body side (for example, a public telephone) breaks down while the IC card is being used, and the pin 13a of the solenoid 13 becomes If the user keeps entering the passage, even if the user tries to pull out the IC card, the IC card 1 is damaged by the pin 13a and cannot be pulled out. , Destroys the device.

Also, during normal operation, the solenoid 1
There has been a problem that the IC card cannot be ejected unless an operation for energizing the device 3, for example, an on-hook operation of the handset is performed.

An object of the present invention is to solve this problem and to provide an IC card processing device which can cope with automatic card ejection and a user's forcible card withdrawal operation.

[0015]

In order to solve the above-mentioned problems, an IC card processing device of the present invention has a card insertion port for receiving an IC card on one surface side, and the card ejection direction is provided on the one surface side.

And a lock member that is supported by the frame and that engages with the second slide member when the IC card enters the predetermined position to restrict the return of the second slide member toward the card insertion opening. Supported by the frame, and an electromagnetic driving body that releases the engagement between the lock member and the second slide member by energization drive and returns the second slide member in the card insertion port direction,
The card stopper formed to be movable back and forth in the card passage between the card insertion opening on the bulging portion side of the card slot and the frame, and at least the first spring member have a force to return the IC card toward the card insertion opening. A third spring member for urging the card stopper in the card passage direction with a large urging force, and a restricting portion for restricting the movement of the card stopper in the card passage direction by the third spring member are provided. The second slide member and the card stopper are connected to each other via a section, and when the second slide member moves to the back side, the restriction section is moved in a direction in which the card stopper enters the card passage. , When the second slide member moves to the card insertion slot side, the card stopper moves in the direction in which the card stopper exits from the card passage. A connecting mechanism for moving the card stopper following the second slide member, wherein the card stopper is configured such that when the IC card enters the predetermined position and the slide member reaches a position for engaging the lock member. The third spring member is brought into contact with the rear end of the IC card to restrict the return of the IC card by the urging force of the third spring member, and to receive an external force in the direction of pulling out the IC card at the predetermined position. Against the urging force of the second
The slide member is configured to move in the exit direction independently of the slide member.

With the above construction, in the IC card processing apparatus of the present invention, when the IC card is inserted from the card insertion slot, the first slide member is pushed by the tip of the card and the first spring member moves. It moves to the back side against the biasing force,
The second slide member moves inward together with the first slide member against the biasing force of the second spring member. And
When the IC card reaches the specified position, the lock member
The second slide member is restricted from returning toward the card insertion opening by being engaged with the slide member of the second slide member, and the card stopper moved to the card passage side by the second slide member moves to the rear end of the IC card. And the return of the IC card due to the urging force of the first spring member is restricted. When the electromagnetic drive body is energized from this state, the engagement between the lock member and the slide member is released, and the second slide member returns toward the card insertion slot by the urging force of the second spring member, and is driven accordingly. The card stopper exits the card passage and the IC card returns to the card insertion slot side. When an external force is applied to the IC card whose rear end is in contact with the card stopper in the pull-out direction, the card stopper withdraws independently of the second slide member against the biasing force of the third spring member. Moving in the direction, the rear end of the IC card is passed to the card insertion slot side.

As shown in FIG. 2, a switch 120 is fixed to the rear portion of the substrate 34 as a sensor for detecting that the external terminal of the IC card has reached a predetermined position where it comes into contact with the contact terminal 42. There is. This switch 12
0 is the first when the IC card has reached the specified position.
The slide member 47 is pushed and closed by the rear portion.

In the vicinity of the switch operating piece 108 of the drive lever 105, whether the drive lever 105 is on the second slide member 55 side or is pulled in by the solenoid 115, that is, the lock member 100 is the second slide member. The switch 121 is fixed as a sensor for detecting whether or not the member 55 is engaged.

Incidentally, each contact terminal 42 and the solenoid 115
The switches 120 and 121 are connected to a control unit (not shown) of the public telephone. In addition to the normal call control of public telephones, this control unit determines the card insertion / ejection state from the on / off states of the switches 120 and 121,
Information is read from and written to the inserted card through each contact terminal 42, and the solenoid 115 is energized to eject the card at the end of a call or the like to prevent the card from being inserted when an abnormality occurs.

Next, the operation of the card processing device 20 will be described. When the IC card 1 is inserted from the card insertion slot 25 of the card slot 22 and the tip of the IC card 1 comes into contact with the card receivers 49, 49 of the first slide member 47, the first slide member 47 receives the card receiver. The front end of the card is received in the recesses 49a, 49a of the 49, 49, and the IC card 1 is pushed horizontally by the IC card as shown in FIG. Slide to move.

Then, when the card enters further,
The rear end of the first slide member 47 is the second slide member 5
5 abuts on the abutment piece 58, and the first piece as shown in FIG.
The slide member 47 and the second slide member 55 slide inward. At this time, since the first connecting lever 70 moves to the back side together with the second slide member 55, the second connecting lever 80 rotates counterclockwise in FIG. 6, and the third connecting lever 85 moves the card. Slide to the insertion port 25 side. Therefore, the card stopper 90 is shown in FIG.
As shown in (a) of FIG.
It rotates counterclockwise so as to enter into the card passage between the card 5 and the card storage portion 38.

Then, when the IC card 1 is inserted to a predetermined position where each external terminal comes into contact with the contact terminal 42, the tip 102a of the engaging piece 102 of the lock member 100 is moved as shown in FIG. 6C. By engaging with the step portion 60 of the second slide member 55, the return of the second slide member 55 toward the card insertion slot is restricted.

At this time, the rear end of the IC card 1 is in contact with the rear portion of the claw portion 93 at a position where it passes through the claw portion 93 of the card stopper 90, as shown in FIG. 7B. . Here, the second slide member 55 by the spring 68
Is smaller than the engaging force between the lock member 100 and the second slide member 55, and the spring 51 moves the first slide member 47 into the card insertion slot 2.
The force of returning in the five directions is smaller than the connecting force of the spring 79 between the second slide member 55 and the first connecting lever 70 (the force for urging the card stopper 90 toward the card passage side). Therefore, if the user releases his hand from the IC card 1, I
The C card 1 tries to move in the direction to be ejected from the card insertion opening by receiving the return force of the first slide member 47, but the movement is restricted by the card stopper 90, and the IC card is moved to the card insertion opening side. I can't go back.

At this time, the switch 120 is pushed by the first slide member 47 to be closed, and the switch 121 is pushed by the switch operation piece 108 of the drive lever 105 to be closed.

The above-mentioned control unit uses the two switches 1
When the IC cards 20 and 121 are closed, it is detected that the IC card is inserted and that the IC card is held at a predetermined position (a position where the external terminal comes into contact with the contact terminal 42) in the card housing portion. The information on the IC card is read through the card, the information can be read correctly, and if the IC card has frequency information, the public telephone is used when the frequency information remains as much as necessary for communication use. To be available.

Then, for example, the control unit which has detected the end of the use of the call by the on-hook operation of the handset writes the necessary information to the IC card at the end of the use, and then temporarily energizes the solenoid 115. .

By this energization, the drive lever 105 is
As shown in FIG. 8A, the solenoid 115 is moved to the main body side, the lock member 100 is rotated counterclockwise, and the tip 102a of the locking piece 102 is moved to the second slide member 55.
It is separated from the stepped portion 60.

Therefore, the second slide member 55 returns to the card insertion slot 25 side together with the first connecting lever 70 by the action of the spring 68, and accordingly, the second connecting lever 80 rotates clockwise. Then, the third connecting lever 8
5 slides inward and the card stopper 90 is shown in FIG.
As indicated by (c), the claw portion 93 at the tip of the pivot portion retreats upward from the card passage.

As a result, the return regulation for the IC card 1 is released, and the IC card 1 has the first slide member 4
Along with 7, the spring 51 moves to the card insertion slot 25 side, and the rear part of the card that has entered the bulged portion 23 side is projected from the card insertion slot 25.

The user notices the ejection of the IC card and pulls out the IC card 1 from the card insertion slot 25.

The energization of the solenoid 115 by the control unit is similarly performed when the information on the card cannot be correctly read due to a failure of the IC card or an error in the front and back of the card, or when there is no remaining frequency of the card. Then, the IC card is ejected. The card stopper 90 retracted from the card passage by the energization of the solenoid 115 maintains the retracted state and does not prevent the next card from entering.

In addition, when the public telephone is used with a magnetic card, coins, etc. after the IC card is once inserted to a predetermined position, when the use of the telephone call itself is stopped, or when the public telephone itself breaks down, the user is It is possible to manually pull out the IC card 1 having the rear portion projected from the card insertion opening 25 of the insertion / removal operation portion 24 of the card slot 22.

That is, when a force is applied to the IC card 1 from the outside in the ejecting direction, the force acts in the direction of rotating the card stopper 90 in the clockwise direction (in FIG. 7). 8 is transmitted to the first connecting lever 70 via the connecting lever 85 and the second connecting lever 80, and the first connecting lever 70 resists the tension of the spring 79 as shown in FIG. 8B. And slides on the second slide member 55 toward the card insertion slot 25 side.

Therefore, in the card stopper 90, the claw portion 93 is pushed to the rear end of the IC card 1 and is rotated clockwise in the same manner as in FIG. The contact with the claw portion 93 is released, and the IC card 1 can be forcibly pulled out. At this time, the card stopper 90
Rotates independently of the second slide member 55 that is engaged with the lock member 100 and its movement is restricted, and the engagement state between the second slide member 55 and the lock member 100 is maintained. ing.

When such a compulsory card withdrawal operation is performed, the first slide member 47 returns to the card insertion slot 25 side together with the card. By opening the switch 120, it is possible to know that the card has been removed.

Then, when the control section determines that the forced pulling operation is due to the user's convenience, the solenoid 115 is temporarily energized, and the second slide member 55 is turned on.
And the lock member 100 are disengaged, and the card stopper 90 is withdrawn from the card passage so as not to interfere with the insertion of the next card.

Further, when a failure occurs on the public telephone side including the IC card processing device 20 and the above-mentioned forced card withdrawal operation is performed, the control unit causes the card to be withdrawn after the card is withdrawn. Does not energize the solenoid 115, and keeps the claw portion 93 of the card stopper 90 in the card path, and prevents the next card from being inserted.
Prevent abnormal writing to the C card. Further, even when a failure occurs in which the energizing function itself stops, the state in which the claw portion 93 of the card stopper 90 has advanced to the card passage is maintained, so that the insertion of the next card can be prevented.

In this IC card processing device 20,
A spring 79 for urging the card stopper 90 toward the card passage side is hooked between the first connecting lever 70 and the second slide member of the connecting mechanism, and the tension of this spring 79 causes the second slide member 55 to have a tension. Since the load for moving the IC card to the back side is not applied, the IC card can be inserted to the back even with a weak force.

[Other Embodiments] In the above embodiment, the connecting mechanism is the first,
Although the second and third connecting levers 70, 80, 85 are used, this connecting mechanism includes a card stopper and a second slide member in a state where movement of the card stopper in the card passage direction by a spring is restricted. The card stopper is moved by the second slide member so as to move forward and backward in the card passage, and the card stopper is provided with a spring against the forced card withdrawal operation. It suffices if it can be moved in the direction of exiting from the card passage independently of the second slide member against the power.

For example, the connecting mechanism can be constructed only by a rotatable connecting lever such as the second connecting lever 70. In this case, one end of the connecting lever is engaged with the card stopper, and the other end of the connecting lever is used as a regulating portion to abut against the second slide member by the urging force of the spring, so that the card stopper can be moved to move the second slide member. When the card is driven so as to be driven, the other end of the connecting lever pivots independently so as to separate from the second slide member against the urging force of the spring when the card is forcibly pulled out. The stopper may be configured to exit the card passage.

Further, the second slide member and the card stopper may be directly connected. For example,
A regulation portion that can come into contact with the card stopper is provided at an end portion of the second slide member, and the regulation portion and the card stopper are brought into abutment with each other by the tension of the spring to move the second slide member. Are connected so that they are driven by the card stopper, and in response to a forced card withdrawal operation, the card stopper pivots independently from the second slide member against the biasing force of the spring and withdraws from the card passage. To configure.

Further, in the above embodiment, the third spring member (spring 79) for urging the card stopper toward the card passage is hooked between the connecting mechanism and the second slide member. The spring member of 3 is hung between the frame and the connecting mechanism or between the frame and the card stopper so that the second slide member and the card stopper are connected while the card stopper is biased toward the card passage side. May be.

Further, in the above embodiment, the lock member 10
Although the solenoid 115 is used as an electromagnetic driving body for rotating 0 to release the engagement with the second slide member, an electromagnet is used instead of the solenoid, and one end side of the lock member is directly electromagnetically attracted. Then, the engagement with the second slide member may be released.

Further, in the above-mentioned embodiment, the card slot 22 having the card insertion opening and the frame 31 are formed separately, but they may be integrally formed. Moreover, various modifications can be made to these shapes. Also,
The bulging portion of the card slot of the above-described embodiment is formed so that one side of the rear portion of the card is exposed from the card insertion opening, but only the central portion of the rear portion of the card is exposed from the card insertion opening. In addition, a card slot having a concave shape on both sides may be used.

In the above embodiment, the present invention is applied to an IC card processing device for manually inserting a card. However, an IC card having a mechanism for pulling the card inserted into the card insertion slot inside The present invention can also be applied to a processing device.

[0077]

As described above, according to the IC card processing apparatus of the present invention, when the first slide member is moved to the back side by being pushed by the tip of the IC card which has entered the card storage portion from the card insertion slot, The second slide member is pushed by the first slide member to move to the back side together with the first slide member, and when the IC card enters to a predetermined position where the external terminal is connected to the contact terminal, the second slide member is moved. The lock member is engaged with the member to restrict the return of the second slide member in the card insertion opening direction, and the card stopper connected to the second slide member via the connecting mechanism is expanded. When the electromagnetic drive is energized from this state, the return of the IC card is regulated by entering the card passage to a position where it abuts the rear end of the IC card that has entered the exit portion. The engagement between the id member is configured to be released.

Therefore, it is possible to automatically discharge an IC card, which has entered a predetermined position and whose return is restricted, from the card insertion slot by energizing the electromagnetic drive, and if this energization is performed at the end of use of the device, etc. The user does not have to forget the IC card.

When an external force is applied to the IC card in the predetermined position in the direction of pulling it out, the card stopper that receives the external force from the rear end of the IC card resists the urging force of the third spring member to generate the second force. Since it is configured to move in the retreat direction independently of the slide member, the device main body side has a failure while the IC card is in the predetermined position, and the electromagnetic drive cannot be energized. Also, when the user pulls the exposed card from the card insertion slot, the card stopper moves in the exit direction, and the card can be easily pulled out without damaging the IC card or causing the card processing device to malfunction. it can. Further, the card can be easily pulled out without performing a special operation for energizing the electromagnetic drive during normal operation, and both automatic ejection and forced withdrawal operation can be achieved.
