BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card processing device for processing a card having a data track and a timing track.

[Prior Art] In a conventional card processing device, a so-called card reader / writer having both a function of reading a remaining number recorded on a card and a function of rewriting the remaining number is used, and in particular, a magnetic card reader that handles a magnetic card. -Writers (hereinafter referred to as card readers) are often used. However, since this card reader has a writing function, the card can be tampered with illegally. Therefore, an erasable card reader having a function of only erasing the residual number written in advance on the card is considered. ing.

In addition, the first erasing means for erasing the corresponding valid value mark information from the data track according to the address based on the read valid value mark information by the charging signal generated at the start of the service, and the service from the start of the service. Storage means for accumulating and storing charge signals generated one by one in response to the provision of each service until the end of the service, and for the storage means based on the effective value mark information erased at the start of the service at the end of the service. The valid value mark information corresponding to the stored value is shared by the previous data tracks according to the address. A second erasing means for erasing is provided.

In the second invention, the mark information obtained by subtracting "1" from the effective value mark information is erased at the start of the service, and only one timing track is erased, and the service is permitted when the erase is confirmed by the reading sensor. It is a thing.

In the third invention, the address determining means for determining the address of the valid value mark information recorded on each data track is configured to count the timing pulse read from the timing track.

The fourth invention is configured such that the address is determined by the address data read from a plurality of address tracks recorded on the card.

In a fifth aspect of the invention, the above-mentioned address is a pattern of address data read from each of a plurality of address tracks recorded on a card, and an output of a counting means for counting the repetition of this address data pattern. It is configured to be decided based on the above.

The sixth aspect of the invention is configured to check the valid value mark information erased at the end of the service on all data tracks.

In addition, a seventh aspect of the present invention determines that the sum of the address number indicating the above address and the effective value mark information number indicating the address of the effective value mark information is a constant value. When obtaining one of the numbers, a means for subtracting the other of the address number and the valid value mark information number from the above-mentioned fixed value is provided.

[Operation] The service is permitted when the valid value mark information read out from each data track at the start of the service is matched, and the charging signal generated at the start of the service provides a response based on the read valid value mark information. The valid value mark information is erased from the data track according to the address, and the charging signal that occurs one by one from the start of the service to the provision of this service is added up and stored as the value of the service until the service ends. When the service ends, the effective value mark information corresponding to the value stored in the storage means is erased in common to all data tracks based on the mark information of the effective value erased at the start of the service.

Further, the mark information obtained by subtracting "1" from the valid value mark information is erased from one timing track at the start of the service, and the service is permitted when the erase is confirmed.

The address of the effective value mark information recorded on each data track is determined by the timing pulse read from the timing track.

The address of the valid value mark information is determined by the address data read from the plurality of address tracks recorded on the card.

The address of the valid value mark information is determined based on the pattern of the address data read from each of the plurality of address tracks and the output of the counting means for counting the repetition of the pattern of the address data.

Also, the valid value mark information erased at the end of the service is checked on all data tracks.

Further, the sum of the address number indicating the above address and the effective value mark information number indicating the address of the effective value mark information is determined to be a constant value, and one of the address number and the effective value mark information number is set. When obtaining, the other one of the address number and the valid value mark information number is subtracted from the fixed value.

EXAMPLES Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment in which the card processing device of the present invention is applied to a card-type public telephone. In the figure, 21 is a CPU that controls this card processing device, and 22 is a CPU.
Is a reading / erasing unit for reading and erasing the frequencies recorded on the card, 23 is a thermal head driver for driving the reading / erasing unit 22 to erase the frequencies recorded on the card,
24 is a card transport mechanism for transporting cards, and a is a billing signal coming from a line (not shown). And read
The erasing section 22 is configured as follows. That is, SA1,
SA2, SB1, SB2, SC1, SC2, SD are sensors for reading the card, and H1, H2 are heads for erasing the card frequency.

Next, FIG. 2 is a configuration diagram showing a configuration of a card used in this card processing apparatus. In the figure, 25 is a card, T1 and T2 are data tracks on which data, that is, frequencies are recorded, T3 and T4 are address tracks, and T5 is a timing track. Then, the card 25 is conveyed in the direction of the arrow and returned in the opposite direction.

The sensors SA1 and SA2 among the above-mentioned heads and sensors are linearly arranged in the direction perpendicular to the card conveying direction, and the heads H1 and H2 and the sensors SC1, SC2, and SD are similarly arranged in the card conveying direction. Is linearly arranged in the direction perpendicular to (the head axis), and the sensors SB1 and SB2 are also linearly arranged in the direction perpendicular to the same. Among these heads and sensors, the sensor SA1, the head H1, and the sensor SB1 are linearly arranged in the card transport direction, that is, in the horizontal direction, and the sensor SA2, the head H2, and the sensor SB2 are also linear in the horizontal direction. It is arranged in a way.

In the present embodiment, the distance between the sensors SA1 and SA2 and the head axis corresponds to 3P of a timing pulse (described later) recorded on the timing track T5, that is, 3 pulses, and the head axis and the sensor SB1. , The distance from SB2 corresponds to two timing pulses, but the distance between them may be any number of pulses.

Next, FIG. 3 is a timing chart showing the timing of patterns recorded on each track of the unused card 25. Figures (a) and (b) show the pulse waveforms of the frequency part recorded on the data tracks T1 and T2, respectively.
10 pulses for each, that is, the frequency part showing 10 frequencies ~
(Effective value mark information) is recorded. And the frequency part recorded on this data track T1, T2 is
When this public telephone is used, the heads H1 and H2 provided correspondingly erase only the part corresponding to the frequency used in the direction from the frequency part to the frequency part shown in the figure, and this erased part It is detected by the sensors SA1 and SA2 or the sensors SB1 and SB2 provided correspondingly.

Further, FIGS. 3C and 3D show the waveforms of the address pulse recorded on the address tracks T3 and T4, respectively, and 1 to 17 in the figure represent the address values. Further, 1 is a start address value and 17 is an end address value, both of which have the value of the address pulse on the address tracks T3 and T4 being "1". Then, if the number of address tracks is n, 2 ⁿ address patterns are recorded. Since the number of address tracks is 2 in this embodiment, the address pattern is 2 ² = 4.
Becomes

That is, 1001 ... in series on the address track T3.
.. The address pulse pattern of 1010 ... Is recorded in series on the address track T4.
When read in parallel by SC1 and SC2, four patterns of 11,00,01,10 can be read as one cycle. Further, in the case of the present embodiment, the number of address patterns is four, whereas the frequency part is 10 and the number of frequency parts exceeds the number, so the period of the address pattern is counted,
An address value is obtained from the counted result and the value of the address pattern at this time.

When the number of address tracks is large and therefore the number of address patterns is large, the value read in parallel by a sensor provided corresponding thereto may be used as the address value. Further, a count value obtained by detecting a timing pulse on a timing track T5 which will be described later and counting it may be used as an address value. And this address track
The value of the address pulse recorded on T3 and T4 is detected by the sensors SC1 and SC2 provided corresponding to each. Note that the positional relationship between the address values 1 to 17 and the frequency part is complementary, and for example, the sum of the address of a certain frequency part and the address value located in the vertical direction is all.
The number is 14, and the address value can be calculated if the position of a certain frequency part is known in advance.

Further, FIG. 6E shows the waveform of the timing pulse recorded on the timing track T5, and as shown in the figure, the timing pulse by the "1" and "0" signals at a constant time interval is recorded. This timing pulse is detected by the sensor SD.

Next, FIGS. 4 to 6 are timing charts showing the outline of the operation of this card processing apparatus. In addition, from FIG.
Each of FIGS. 6A to 6E is a data track.
6 is a timing chart corresponding to T1 to timing track T5. The outline of the operation of this device will be described with reference to FIGS.

When the card 25 is inserted into the insertion slot for carrying out a call, the CPU 21 carries the card 25 to the card carrying mechanism 24 and controls the scanning of the sensor SD to generate a timing pulse on the timing track T5 of the card 25. When scanning is performed and the "1" portion of the timing pulse is detected, the sensors SC1 and SC2 are scan-controlled to detect the respective address pulses on the address tracks T3 and T4. Then, when both the address pulses become "1", this address is recognized as the start address 1.

Next, the sensors SB1 and SB2 are used to further control the conveyance of the card in order to detect the frequency section on the data tracks T1 and T2, and as shown in FIGS. It is conveyed to a position where both the frequency parts recorded in T1 and T2 are "0", that is, the frequency part in the example of this figure. This frequency part is the maximum erased value of the card 25. The position of the head axis at this time, that is, the address value is calculated by the following equation.

Address value = 2AT3 + AT4 + 4N-2 Here, AT3 and AT4 are the values of the address pattern read by the sensors SC1 and SC2 at this time, respectively, and N is the number of pattern cycles counted until the address value is reached. However, that is counted as one at the start address AT _S point in time. At this time, both AT3 and AT4 are "1" and N is 1, so that the address value = 2 × 1 + 1 + 4 × 1-2 = 5.

Further, FIG. 5A shows an example in which the frequency part on the data track T1 is not erased for some reason. In such a case, the CPU 21 performs error processing.

Then, as shown in FIG. 4, the card 25 is conveyed to the position of the frequency part, and it is detected that both of the frequency parts on the data tracks T1 and T2 have been erased to become "0". When the billing signal a indicating the start of the call is received, the CPU 21 causes the thermal head driver 23 to drive the head H1 to erase the frequency part indicated by the dotted line portion, as shown in FIG. 6 (a). . That is, an address obtained by subtracting one degree from the maximum erase value of the card 25 is calculated, the card 25 is conveyed to this position, the head H1 is made to face the frequency portion on the data track T1, and only this frequency portion is erased.

At this time, the address value of the head H1 facing the frequency part is 8 because the address of the frequency part is 8.
14-8 = 6. In addition, the frequency part on the data track T2 is not erased as a countermeasure in case the used frequency is not erased for some reason.

Then, after that, the card 25 is conveyed again and the sensor SA1 and this frequency part are made to face each other. In this case, if the maximum address value is 17, the address of the frequency part is 8, 17-8 = 9. Then, the card 25 is conveyed so that the position of the address value 9 reaches the head shaft, and the sensor SA1 is made to detect whether or not this frequency part has been erased.

After that, when the call ends, the CPU 21 conveys the card 25 to a position corresponding to this call frequency, and erases the predetermined frequency portion on the data tracks T1, T2 by the heads H1, H2.

If two calls are used in this call, the maximum delete count is 7, so the delete count is 7.
+ 2 = 9, and the frequency part is deleted. After the part corresponding to the call frequency is deleted in this way, CPU2
1 carries the card 25 for returning, but the frequency part erased at this time is checked by the sensors SB1 and SB2.

The positions of the sensors SB1 and SB2 are at a distance of 2 addresses from the head axis, and the position of the frequency part in the vertical direction of the point where the sensor is located and the position of the head axis are in a complementary relationship. The sum of these positions, or addresses, is
It is always 12 and is constant. Therefore, the sensors SB1, SB
The address value when 2 corresponds to this erased frequency part is 12-9 = 3, and the card 25 is conveyed so that the position of this address value 3 reaches the head axis, and the sensor SB1,
Let SB2 check for this erasure.

Next, the detailed operation of the card processing device of the present invention will be described with reference to the flowchart of FIG.

When the card 25 is inserted, the CPU 21 controls the transportation of this card. After that, in step 50, the output of the sensor SD facing the timing track T5 changes from "0" to "1".
It is determined whether or not it has changed to. If it is "N", wait until it changes to "1". If it is "Y", step 51
Scan all sensors at step 52
In order to detect the start position of 25, it is particularly determined from the sensors whether or not the outputs of the sensors SC1 and SC2 are both "1".

And when this is "N", it returns to step 50,
If the result is "Y", it means that the start position has been detected, and it is determined in step 53 whether the output of the sensor SD has changed from "0" to "1". Then, when it is "N", it waits until it changes to "1", and when it is "Y", step 54
At step 55, all the sensors are scanned, and it is determined at step 55 whether or not the output of the sensor SB1 or the sensor SC2 is "0". And "N"
If so, the process returns to step 53, and if "Y", then at step 56, it is determined whether or not the sensors SB1 and SB2 both become "0".

When the result is "N" in step 56, as will be described later, it means that the card 25 has not been erased even though it has been used, so that error processing is executed in step 57. If the answer is "Y" in step 56, it means that the card 25 is normal. Therefore, in step 60, the remaining frequency of the card 25 is calculated, and in step 61, the frequency part obtained by subtracting 1 from the remaining frequency of the card 25 is deleted. The position of the head H1 for this purpose is calculated, and the card 25 is stopped in step 62.

After that, when the calling party dials, the arrival of the billing signal a due to the called party's response is judged in step 63, and when "N", that is, if the billing signal a cannot be received, wait until it can be received. If "Y", that is, if reception is possible, the card 25 is re-conveyed in step 64. Then, in step 65, it is determined whether or not the output of the sensor SD has changed from "0" to "1". Then, when it is "N", it waits until it changes to "1", and when it is "Y", all the sensors are scanned in step 66, and in step 67, the portion of the card 25 that is erased once is the position of the head H1. To see if you came to. And when "N", step
Return to 65.

When the result is "Y" in step 67, it means that the card has been conveyed to a predetermined position, so in step 70 the head H1 erases a predetermined number of times of the data track T1 in the card 25. Then, in step 71, the position of the sensor SA1 for detecting the erased portion is calculated, and in step 72, it is determined whether or not the output of the sensor SD has changed from "0" to "1". Then, when it is "N", it waits until it changes to "1", and when it is "Y", all the sensors are scanned in step 73, and in step 74, the erased portion of the card 25 is the sensor.
Determine whether you have come to the position of SA1. When it is "N", the process returns to step 72.

If "Y" in step 74, ie card 25
When the erased portion of is located at the position of the sensor SA1, it is judged at step 75 whether the output of the sensor SA1 is "0". If this is "N", it means that the head H1 could not erase the portion of the data track T1 of the card 25, so that error processing is performed in step 57. If step "Y", the card 25 is stopped in step 76,
In step 77, the end of the call is judged. When it is "N", it waits until the end of the call, but during this period, the billing signal a arrives at every predetermined call time, and the call frequency corresponding to this billing signal a is built in the CPU 21. It is accumulated and stored in memory one by one.

When the answer is "Y" in step 77, that is, when the call ends, the remaining frequency is calculated based on the frequency used in step 80, and in step 81, return transportation for returning the card 25 is performed. Then, in step 82, it is determined whether or not the output of the sensor SD has changed from "0" to "1".
And when it is "N", wait until it changes to "1",
If "Y", all the sensors are scanned in step 83, and it is determined in step 84 whether the card 25 has reached the position to be erased. When it is "N", the process returns to step 82.

If "Y" is determined in the step 84, that is, if the card 25 is conveyed to the position to be erased, the heads H1, H2 are determined in a step 85
By erasing a predetermined frequency portion of the data tracks T1, T2, the output of the sensor SD is changed from "0" to "1" in step 86 in order to confirm whether or not the erased portion is erased.
It is determined whether or not has changed. If it is "N", wait until it changes to "1", and if it is "Y", step 87
Scan all sensors at step 88
It is determined whether or not the erased portion of 25 has been conveyed to the positions of the sensors SB1 and SB2. When it is "N", the process returns to step 86.

In step 88, when "Y", that is, the card
When 25 is conveyed to the positions of the sensors SB1 and SB2, it is determined in step 89 whether the outputs of the sensors SB1 and SB2 are both "0". And when this is "N", head H
Since it could not be erased by 1, H2, step 57
Error handling with. If “Y” is determined in step 89, that is, if the data can be erased normally, in step 90 the sensor
It is determined whether the output of SD does not change, that is, whether the card 25 has been returned, and when it is "N", it waits until it is returned, and when it is "Y", that is, when it is returned, it ends.

In the present embodiment, the thermal head was used as the erasing head and the magnetic sensor was used as the reading head. However, a puncher for punching a card is used as the erasing head, and the reading head is composed of a light emitting element and a light receiving element. You may make it use the optical sensor mentioned above.

Further, an element for changing the reflectance of the card may be used for the erasing head, for example, a thermal head using a thermal card or an ink stamp stamp element, and an optical sensor such as a light receiving element may be used for the reading head.

Further, in the present embodiment, an example in which the card processing device is applied to the card type public telephone has been described, but the present invention is not limited to the card type public telephone, and may be applied to other card systems.

[Effects of the Invention] As described above, the card processing device of the present invention permits the service when the valid value mark information read from each data track at the start of the service coincides with the charging signal generated at the start of the service. The corresponding valid value mark information is erased from the data track according to the address based on the read valid value mark information, and the charging signal generated one by one in response to the provision of this service from the start of the service is divided into the value of the service. As a result, when the service ends, the values are accumulated and stored one by one, and when the service ends, the effective value erased when the service starts is based on the mark information and the effective value mark information corresponding to the value stored in the storage means All data tracks are erased so that you can erase and erase each time. Therefore, there is an effect that it is not necessary to perform the confirmation, and therefore the consumption of mechanical and electrical energy can be suppressed, and a device with low power consumption can be configured.

Also, the mark information obtained by subtracting "1" from the valid value mark information is erased from one timing track when the service is started, and the service is configured to be permitted when the deletion is confirmed. There is an effect that the quality of can be judged.

Further, since the address of the effective value mark information recorded on each data track is configured to be determined by the timing pulse read from the timing track, it is possible to detect the address without providing the address track. is there.

Further, since the address of the valid value mark information is configured to be determined by the address data read from the plurality of address tracks recorded on the card, there is an effect that reliable address detection can be performed.

Further, since the address of the effective value mark information is determined by calculating the address data and the value obtained by counting the repetition of the address pattern, it is possible to have more effective value mark information in a smaller number of address tracks. is there.

Further, since the valid value mark information erased at the end of the service is configured to be checked on all the data tracks, there is an effect that the erasure of the card can be surely detected.

Further, the address number is assigned in a complementary relationship to the number indicating the effective value mark information, and the other number is calculated from the obtained one number, so that the address can be easily calculated. There is.
