A control signal from a control unit (not shown) in the IC card 8
The data processing is performed by sending to 0.

Next, the processing operation of a card in a public telephone having such a configuration will be described. First, when the handset 6 is detached from the hook portion 5 of the hanger arm 4 for making a call, as shown in FIG. 3, the hanger arm 4 is rotated clockwise about the shaft 14 by the tension coil spring 16 around the shaft 14 as shown in FIG. To rotate. Following this rotation, the lever 17 moves in the direction opposite to the arrow C, so that the pressing lever 2
0 rotates counterclockwise around the pin 19, and the roller 24 is separated from the arm 65 b of the holding lever 65.

At this time, the pin 69 of the holding lever 65 of the card reader 35 and the step 60c of the operating lever 60 are
The non-engaged state is maintained as shown in FIG.
The operating lever 60 is moved in the direction of arrow A by the urging force of the extension coil spring 62. Therefore, the operating lever 6
The shutter 71 connected to the 0 operating portion 60d rotates clockwise about the pin 72 as shown in FIG. 2B, and the shutter portion 71a opens the card insertion slot 3. Further, the pin 57 of the relay lever 55 is
0 is pushed in the direction of arrow A by the projection 60b, so that the relay lever 55 pivots clockwise in FIG.
Facing the back.

In this state, when the IC card 80 is inserted from the card insertion slot 3 into the card insertion path 45, the IC card 8
The leading end of the abutment 0 contacts the front end of the projection 50b of the moving element 50.
When the IC card 80 is further inserted, the movable element 50 descends in the direction of arrow A against the tensile force of the extension coil spring 52 while the dowel 50a of the movable element 50 is guided by the guide groove 47a of the guide wall 47. While moving. As shown in FIG. 7, when the IC card 80 is completely inserted, the rear end of the convex portion 50b of the moving member 50 comes into contact with one end 55a of the relay lever 55, and the relay lever 55 is turned around the pin 56 as a rotation center. Rotate clockwise. By this rotation, the pin 57 comes into contact with the projection 60b of the operation lever 60, and moves the operation lever 60 in the direction of arrow B in the drawing against the pulling force of the tension coil spring 62. Rotates counterclockwise in the figure around the pin 72 as a rotation center, and the shutter 71 a closes the card insertion slot 3.

At this time, since the holding lever 65 is urged clockwise in the figure around the pin 66 by the tension coil spring 68, the pin 69 of the holding lever 65 is engaged with the step portion 60 c of the operating lever 60. Combined, tension coil spring 6
The movement of the operating lever 60 in the direction of arrow A due to the pulling force of 2 is prevented. Therefore, the shutter section 7 of the shutter 71
Since the closed state of the card insertion slot 3 due to 1a is also maintained, the IC card 80 inserted into the card insertion slot 45 is retained.
Tries to move in the direction of arrow B by the tensile force of the tension coil spring 52 of the moving element 50, but since the rear end is locked by the shutter portion 71a, the card insertion slot 3
And is held in the card insertion path 45. In this state, data processing of the IC card 80 corresponding to the number of calls is performed via the contacts 51 of the contact unit 49 that contacts the electrode section 80a of the IC card 80.

When the call is finished and the handset 6 is hooked on the hook 5 of the hanger arm 4, the hanger arm 4 resists the tension of the tension coil spring 16, as shown in FIG.
Since it rotates counterclockwise around the rotation center 4, a hook switch (not shown) is turned off and the communication line is disconnected. When the hook switch is turned off, the solenoid 67 operates and the rod 67a moves backward against the extension coil spring 68, so that the holding lever 65 rotates counterclockwise in FIG. And the stepped portion 60c of the operating lever 60 is disengaged. Therefore,
Since the operating lever 60 moves in the direction of arrow A by the pulling force of the pulling coil spring 62, the shutter 71 turns clockwise about the pin 72 as shown in FIG. Open the insertion slot 3. When the card insertion slot 3 is opened, the projection 50b of the moving element 50 urged in the direction of arrow B by the tension coil spring 52.
The IC card 80 whose leading end is engaged with the card insertion slot 3
Will be returned from. The time from when the hook switch is turned off to when the solenoid 67 operates is set slightly longer than the time for processing the data of the IC card 80 by the contact unit 49 described above.

When the hanger arm 4 rotates counterclockwise about the shaft 14 as shown in FIG. 4, the lever 17 moves in the direction of arrow C and pulls between the lever 17 and the pin 18. Pin 22 connected via coil spring 23
Also tries to move in the direction of arrow C by the tensile force of the tension coil spring 23. However, since the delay means 26 is connected to the pressing lever 20 on which the pin 22 is implanted, the delay lever 26 causes the pressing lever 20 to rotate in the direction in which the pressing lever 20 is about to rotate, Braking in the opposite direction to the middle clockwise direction is applied. Therefore, pin 2
2 does not move against the tensile force of the extension coil spring 23 despite the movement of the pin 18 in the direction of arrow C,
As shown in the same figure, the lever 17 is located at the upper end side of the long hole 17a.

Thereafter, the pin 22 moves in the elongated hole 17a in the direction of arrow C at a low speed by the tensile force of the extension coil spring 23 against the braking of the delay means 26, as shown in FIG. Since it is located at the lower end, the pressing lever 20 rotates clockwise in the drawing, and the roller 24 comes into contact with the other arm 65 b of the holding lever 65. The moving time of the pin 22 in the long hole 17a, that is, the delay time until the roller 24 comes into contact with the arm 65b is longer than the time until the hanger arm 4 is pushed down by the transmitter / receiver 6 and the above-described solenoid 67 is operated. It is set to be long. In other words, after the call is finished and the hanger arm 4 is pushed down by the handset 6 and the hook switch is turned off, the processing of the data of the IC card 80 by the contact unit 49 is finished, the solenoid 67 is operated and the IC card 80 is turned off. The roller 24 is set so as to come into contact with the arm 65b after returning from the card insertion slot 3.

Therefore, the roller 24 does not come into contact with the arm 65b before the processing of the data of the IC card 80 by the contact unit 49 is completed after the call is completed. For this reason, when the roller 24 comes into contact with the arm portion 65b, the holding lever 65 is rotated counterclockwise in the drawing about the pin 66 as a rotation center, and the engagement between the pin 69 and the stepped portion 60c is released. The opening operation of the card insertion slot 3 of the shutter 71 by the movement of the shutter 60 in the direction of the arrow A is not erroneously performed before the data of the IC card 80 is processed.

If a power failure occurs during a call, the solenoid 67 does not operate.
Card 80 cannot be returned, but hanger arm 4
Is provided, the IC card 80 is returned when the handset 6 is hooked on the hook 5 of the hanger arm 4.
In addition, since the delay means 26 is provided between the initial state return means 25 and the shutter 71, the data is erroneously returned from the card insertion slot 3 before the data of the IC card 80 is processed as described above. There is no such thing.

When the handset 6 is hooked on the hook 5 of the hanger arm 4, the roller 24 of the pressing lever 20 presses the other arm 65b of the holding lever 65 as described above. As shown in FIG. 6A, the holding lever 65 is rotated counterclockwise around the pin 66 against the pulling force of the tension coil spring 68. Accordingly, the state in which the pin 69 of the holding lever 65 is disengaged from the stepped portion 60c of the operating lever 60, that is, the disengaged state is maintained, the operating lever 60 moves in the direction of arrow A, and the card is inserted by the shutter 71. The opening of the mouth 3 is open. Therefore, even if the IC card 80 is inserted from the card insertion slot 3 into the card insertion path 45, the moving member 50
Is urged in the direction of arrow B by the tension coil spring 52, so that the IC card 80 is not returned from the card insertion slot 3 by the mover 50 and is erroneously inserted into the card insertion path 45.

During a call, a part of the IC card 80 held in the card insertion path 45 is exposed from the concave portion 76a provided in the insertion port member 76 as shown in FIG. When the user grips and strongly pulls in the direction of arrow B, the shutter 71 tries to rotate clockwise in the figure by the rear end of the IC card 80. This rotation attempts to move the operating lever 60 in the direction of arrow A, and the pin 69 is disengaged by the obtuse angle at the tip of the stepped portion 60c. The blockage of the insertion slot 3 is released, and the IC card can be forcibly pulled out.
Therefore, since the handset 6 has a discharging means other than the on-hook operation, even if the balance of the IC card runs out during a power outage, the card with no balance is removed without disconnecting the call, and the second card is inserted to carry out the call. You can continue.

In this embodiment, an IC card is used as an example. However, a magnetic card may be used. In that case, a contact unit is not required, and the relay lever 55 is directly rotated by the card. Is also good. In addition, the card-type public telephone is not limited to a card-only machine using only a card, but may be a combination machine used in combination with a coin. In addition, the initial state returning means 25 is linked to the operation of the hanger arm 4 with the handset 6 mounted thereon.
A push button, a rotatable lever, or the like may be provided so as to be linked with the pressing operation of the push button or the rotating operation of the lever, and various design changes are possible.

[0031]

As described above, according to the present invention, even if a power failure occurs during a call, the user activates the initial state return means to activate the delay means, during which the processing of the card is performed. When the processing is completed and the processing is completed, the card is returned, so that the service for the user can be prevented from lowering. Further, in normal times, the operation of releasing the holding means by the initial state returning means is performed after the operation of the solenoid by the delay means, so that the operation of returning the card by the solenoid is not affected.

According to the second aspect of the invention, it is not necessary to add a new part such as a push button or a lever to return to the initial state. In addition, since the operation can be performed by the weight of the handset, the service for the user is improved.

According to the third aspect of the present invention, since the card is not erroneously inserted into the insertion path, the service for the user is improved, and the failure of the apparatus due to the erroneous insertion is prevented. it can.
