Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for carrying a card and recording processing by reducing the value information used for the card when the card is used, and more particularly to a card carrying for ejecting the recorded card. Regarding the device.

[0002]

2. Description of the Related Art Conventionally, value information is previously recorded as magnetic data on a card used in a public telephone or the like. Here, when a card is inserted to make a call using the card, the inserted card is conveyed to the position of the reading head and the value information is read. Is acceptable. Then, when a call is made and this is finished, the value information corresponding to this call is subtracted from the above-mentioned value information and recorded as remaining value information by the write head. After that, the card is conveyed to the position of the punch unit for punching, punched by the punch unit to a position according to the residual value information, and then conveyed to the discharge port and discharged.

[0003]

The conventional card transport device attempts to transport the card to the discharge port after using the card, but the card may not be transported for some reason, and the card is jammed in the card transport path. There was a problem that it occurred.

Therefore, an object of the present invention is to reliably eject the card to the ejection port when the card is conveyed to the ejection port after the card is used, and to prevent the card from being jammed in the card conveyance path.

[0005]

In order to solve such a problem, the present invention provides a sensor for detecting the completion of card ejection, and when the sensor does not detect card ejection, the card is set in the card ejection direction. There is provided a card reverse carrying means for carrying the card backward to a predetermined position in the reverse direction, and a card discharging means for carrying the card backward carried to the predetermined position by the card reverse carrying means in the card discharging direction.

[0006]

When the sensor does not detect the completion of card ejection, the card reverse conveyance operation by the card reverse conveyance means and the card ejection operation by the card ejection means are executed a predetermined number of times. Therefore, the card can be surely discharged to the discharge port by the card reverse transport operation and the card discharge operation of the predetermined number of times.

[0007]

The present invention will be described below with reference to the drawings. FIG. 4 is a sectional view of a card reader / writer device to which the card carrying device according to the present invention is applied. In the figure,
Reference numeral 1 is a magnetic card, and 2 is a card reader / writer device for recording / reproducing and punching magnetic data on / from the magnetic card 1. The card reader / writer device 2 is configured as follows. That is, 21 is an insertion / ejecting port through which the magnetic card 1 is inserted and ejected, 22 is a card transport path, 23 is a head section for performing magnetic recording / reproducing on the magnetic card 1, and 24 is a punch section for punching on the magnetic card. , 25 are sensors for detecting the position of the magnetic card. Also, 26A,
26B is a roller, 27 and 29 are belts, 28 is a pulley,
M is a motor. Here, when the motor M rotates, this rotational force is transmitted to the pulley 28 via the belt 29, and the pulley 28 rotates. The rotation of the pulley 28 causes the rollers 26A and 26B which are interlocked therewith to rotate, and as a result, the magnetic card 1 on the belt 27 is conveyed.

Next, FIG. 1 is a block diagram of a control system of this card reader / writer device, and a CP for controlling this device.
A control circuit 31 such as U is connected via a transmission / reception circuit 32 to a control unit 30 that controls a public telephone, which is a higher-level device of this device. The control circuit 31 is connected to the punch unit 24, the sensor unit 25, and the motor M described above, an EEPROM 33 for storing and holding various parameters necessary for control, and a ROM for storing programs.
34, RAM 35, the contents of which are stored and held by the backup power supply from the control unit 30, the shutter unit 3
6, an optical sensor 37 for detecting a bar code attached to the card 1, and an encoder 30 for detecting the rotation speed of the motor M, that is, the transport speed of the magnetic card 1 are connected.

By the way, when the magnetic card 1 is inserted into the insertion / ejection port shown in FIG. 4, the control circuit 31 rotates the motor M to rotate the pulley 28 and the roller 26A interlocked therewith. As a result, the roller 26B connected to the roller 26A by the belt 27 also rotates and is inserted into the belt 2
The magnetic card 1 above 7 is conveyed to the position where the head portion 23 is arranged.

After that, the control circuit 31 instructs the head unit 23 to read the magnetic data indicating the value information of the magnetic card 1 by the reading head. Then, for example, during a call, certain value information is subtracted from the magnetic data read every time a billing signal arrives, and when the call ends, the head unit 2
3, the value information remaining on the magnetic card 1 is magnetically recorded by the recording head. Then the control circuit 31
Rotates the magnetic card 1 so as to be conveyed toward the insertion / ejection port 21 to convey the magnetic card 1 to the position of the punch section 24, and drives the punch section 24 according to the residual value information of the magnetic card 1. Punch to the punch position.
After that, while monitoring the output of the sensor unit 21 that detects the position of the magnetic card 1, the magnetic card 1 is conveyed to the insertion / ejection port 21 and ejected.

Next, FIG. 2 is a flow chart showing the main part of the operation of this apparatus, which is a control circuit 3 when the magnetic card 1 is ejected.
1 shows the operation of No. 1. As described above, even if the magnetic card 1 is controlled to be conveyed to the insertion / ejection port, there is a problem that the magnetic card 1 cannot be ejected from the insertion / ejection port for some reason. In order to solve this problem, the control circuit 3
1 performs the following card ejection processing. That is, in step ST1, after card processing such as reproduction / recording of magnetic data of the inserted magnetic card 1 and punching processing is performed,
In step ST2, card ejection processing is performed in which the motor M is rotated so that the processed magnetic card 1 is conveyed toward the insertion / ejection port 21.

Thereafter, in step ST3, the sensor unit 25
Is detected to determine "completion of ejection" of the magnetic card 1. If the discharge completion is determined to be "N", it is determined in step ST4 "whether it is executed a prescribed number of times". The specified number of times indicates the specified number of transport operations for ejecting a card, which are executed in steps ST5 and ST6 described later. That is, if the ejection of the magnetic card 1 cannot be detected and the card conveying operation for ejecting the card does not reach the specified number of times, the control circuit 31 determines the motor M in step ST5.
Is reversely rotated to reversely convey the magnetic card 1 by, for example, 2 mm in a direction opposite to the ejection direction of the magnetic card 1 (card reverse conveyance means), and then in step ST6, the motor M is normally rotated in the ejection direction of the magnetic card 1. Magnetic card 1 for example 4
The card is ejected for a mm (card ejection means), and the process returns to step ST3 to determine the completion of ejection of the magnetic card 1.

If the completion of ejection of the magnetic card 1 is detected and the determination in step ST3 is "Y", the magnetic card 1
The process ends as is normally discharged. Further, if it is determined that the "card ejection completion" in step ST3 is "N", the process proceeds to step ST4 and the prescribed number of times of the reverse conveyance indicating the ejection trial of the magnetic card 1 and the normal conveyance after the reverse conveyance is determined again. . If this discharge trial operation is less than the specified number of times, the discharge operation is tried again in steps ST5 and ST6, and even if the discharge trial operation reaches the specified number of times, the discharge of the magnetic card 1 is not detected yet, and the step ST4 If the determination is "Y", it is determined that the magnetic card 1 cannot be ejected because an abnormality has occurred in another part of the apparatus, and an abnormality process is performed to notify the fact, and the process ends.

As described above, when the ejection of the magnetic card 1 is not detected when the magnetic card 1 is conveyed to the insertion / ejection port and ejected, the ejecting operation of conveying the magnetic card 1 in the reverse direction and then again is tried a prescribed number of times. It is something that is done. As a result, the magnetic card 1 can be reliably ejected to the insertion / ejection port 21.

Next, FIG. 3 is a flow chart showing the operation of another embodiment of the present apparatus, showing the operation of the control circuit 31 for controlling the ejection of the magnetic card 1. That is, in this case, the control circuit 31 executes the card processing similar to step ST1 of FIG. 2 in step ST11. Thereafter, in step ST12, card ejection processing is executed, but when the magnetic card 1 is ejected, the motor M is rotationally controlled so that the conveyance speed becomes a normal conveyance speed.

Thereafter, in step ST13, the sensor unit 2
The output of No. 5 is detected to determine "completion of ejection" of the magnetic card 1. If the completion of ejection is determined to be "N", the control circuit 31 determines in step ST14 that the magnetic card 1 has been ejected.
Is reversely conveyed and returned to a predetermined position, and step ST15
Then, the rotation of the motor M is controlled so that the transfer speed of the magnetic card 1 becomes slower than the normal transfer speed.

Then, in step ST16, the sensor unit 25
Is detected to determine "completion of ejection" of the magnetic card 1, and if the completion of ejection is determined to be "Y", the magnetic card 1 is considered to have been normally ejected, and the process ends. When the completion of ejection in step ST16 is determined to be "N", the magnetic card 1 is again reversely conveyed in step ST17 and returned to a predetermined position, and in step ST18, the conveyance speed of the magnetic card 1 is the normal conveyance speed. The rotation of the motor M is controlled to be faster. Then, step ST19
Then, the completion of ejection of the magnetic card 1 is judged again, and this is "Y".
If it is determined that the card is normally discharged, the process ends. In addition, when the “ejection completed” in step ST19 is determined to be “N”, the ejection of the magnetic card 1 is still impossible even if the delivery speed of the magnetic card 1 is changed and the ejection is attempted. Since the magnetic card 1 cannot be ejected due to an abnormality in another part of the device, the processing is ended as it is.

As described above, when the ejection of the magnetic card 1 is not detected when the magnetic card 1 is conveyed to the insertion / ejection port and ejected, the conveyance speed of the magnetic card 1 is changed to perform the ejection trial. is there.
