Description

DETAILED DESCRIPTION OF THE INVENTION <Field of the Invention> The present invention relates to a method of processing a discarded ticket or commuter pass made into a magnetic card.

<< Summary of the Invention >> The present invention provides a method of discarding a ticket or a commuter pass that has been converted into a magnetic card by the NRZ-I system, by removing only the clock pulse track and erasing other data tracks, thereby disposing of the discarded ticket. The processing is performed.

《Prior art and its problems》 Conventionally, in a ticket issuing device that issues a magnetically recorded commuter pass or ticket, if a clerk mistakenly inputs the boarding section, expiration date or fare, etc., to prevent unauthorized use in the future ,
The commuter pass and the like have been discarded (cancelled).

By the way, the discarded ticket processing is performed by erasing all the magnetic recording contents input to the commuter pass or the ticket.

This also applies to the case where after the used ticket is collected by an automatic ticket gate, the ticket is disposed of to prevent unauthorized use in the future. It has been done.

However, in the processing method as described above, all the input magnetic recording contents are erased at the time of scrap ticket processing, so that an unencoded ticket (blank paper ticket) in which nothing is magnetically recorded from the beginning or a customer uses a magnet or the like It is not possible to distinguish between a ticket whose recorded contents have been deleted and a ticket that has been discarded,
When the ticket is inserted into an automatic ticket gate, all of the ticket is treated as a reading error as an abnormal ticket, and there is a problem that the illegal act of using a discarded ticket cannot be particularly prevented.

<< Object of the Invention >> In view of the above problems, an object of the present invention is to provide a magnetic card waste ticket processing method capable of preventing illegal use of used tickets such as used tickets.

<< Structure and Effect of the Invention >> In order to achieve the above object, the present invention is characterized in that, when erasing magnetic information encoded on a magnetic card, only a clock pulse track is left and other data tracks are erased. Is what you do.

According to such a configuration, when erasing the input magnetic information, only the clock pulse track is left and the others are erased, so that it can be distinguished from other abnormal tickets, and the illegal use of discarded tickets can be effectively prevented. It has effects such as being able to.

<< Description of Embodiment >> Next, an embodiment in which the present invention is applied to a magnetic card recorded by the NRZ-I system will be described with reference to the drawings.

FIG. 1 is a block diagram showing an electric system configuration in a case where a waste ticket processing method according to the present invention is applied to a commuter ticket or ticket issuing machine. As shown in FIG. The write data stored in the write data buffer 3 is stored in the write data buffer 3 when the date 4 is opened under the control of the I / O control 7.
, Whereby the writing operation by the writing head 6 is performed.

On the other hand, FIG. 3 is a front view of a commuter pass or a train ticket magnetically recorded in the NRZ-I system. As shown in FIG. 3, data tracks corresponding to the output of the magnetic head are provided on each card. 20 and a clock pulse track 30 are arranged.

That is, the commuter pass card A is provided with two data tracks 20 with the clock pulse track 30 interposed therebetween (FIG. 3 (a)).

The large-sized ticket card B is provided with three data tracks 20 with two clock pulse tracks 30, 30 interposed therebetween (FIG. 3 (b)).

Further, the small-sized ticket card C is provided with one clock pulse track 30 and one data track (FIG. 3 (c)).

By the way, cards recorded magnetically by the NRZ-I method are:
The recorded contents of the data track 20 are reproduced in synchronization with the clock of the clock pulse track 30.

Therefore, no data is reproduced unless a clock is input.

On the other hand, even when the clock of the clock pulse track 30 is input and the recorded content of the data track 20 is reproduced, if the recorded content of the data track is 0, the reproduced data is also 0.

Therefore, if a card that has been magnetically recorded by the NRZ-I system and is inserted into an automatic ticket gate by an unencoded ticket or a ticket that has been accidentally erased by a magnet or the like is not clocked, a reading error will occur, while data will be read. Only the recorded contents of the track are 0
When a ticket is inserted, a reading error does not occur simply because the recorded content of the data is 0, and both can be distinguished by an automatic ticket gate.

In other words, the method shown in the present embodiment can be distinguished from other abnormal tickets (unencoded tickets or tickets mistakenly erased by magnets or the like) by erasing only the data track when discarding the magnetic card. It was made.

FIG. 5 is a flowchart showing the processing procedure of the present embodiment. When a magnetic card such as a commuter pass or a ticket to be discarded is inserted into a discarded ticket insertion slot (not shown) of the ticket issuing machine, the write head is started. By the operation of 6, the data track is written with 0, and only the clock pulse track is left (step 100).

The tickets that have been discarded as described above are collected to prevent unauthorized use in the future (step 102).

FIG. 4 is a front view of the magnetic card which has been discarded by the above-mentioned method. The clock pulse track is provided on the commuter pass A, the large ticket B and the small ticket C.
Only 30 remains, and all data tracks 20 are erased (see FIG. 3).

For this reason, when a card that has been discarded as described above is inserted into an automatic ticket gate, the clock is turned on and it is not treated as a reading error, so it can be distinguished from an unencoded ticket or a ticket whose recorded contents have been accidentally erased by a magnet etc. become.

Next, a case where the waste ticket processing method according to the present invention is applied to an automatic ticket gate will be described.

FIG. 7 is a perspective view of an automatic ticket gate 40 to which the method of the present embodiment is applied.
B is provided, and an entrance card slot 47 is provided in the entrance direction, and an exit card slot 48 is provided in the exit direction.

In the automatic ticket gate 40, the card inserted into any one of the card insertion slots is read, so that the normal ticket lamp 46 for children, the normal ticket lamp 45 for adults, the waste ticket lamp 44 Either the error lamp 43 or the section / date over lamp 42 is turned on.

Next, FIG. 2 is a block diagram showing the electrical system configuration of the method of the present embodiment. Like the method of the first embodiment, this system also has a CUP11 comprising a microprocessor and a memory.
It is composed of 12 microcomputers.

That is, a card inserted into any one of the card insertion slots has its recorded content read via the read head 15, amplified by the read amplifier 14, and stored in the read data buffer 13, and the stored data is As in the first embodiment, the write buffer 16, I / O control 21, gate 17
Is sent to the write driver 18 via the interface, and the writing process (erasing of the data track) is performed by the operation of the write head 19.

On the other hand, in this system, the opening / closing operation of the gates 41A, 41B and the operation of each lamp 42, 41 are controlled by the control of the I / O control 21.
Lighting control of 43,44,45,46 is performed.

The system of the second embodiment is constructed as described above. Next, the processing procedure of the system when a ticket is inserted into the automatic ticket gate 40 will be described in detail with reference to the flowchart of FIG. I do.

First, when a program is started by inserting a ticket into one of the card slots waiting for card insertion (step 200), it is determined whether the inserted ticket is for entry or exit. (Step 202).

If the ticket is for entry into the card slot 47 on the entrance side (YES in step 202), the following processing is performed.

That is, first, the recorded contents of the ticket are read (step 236), and it is confirmed whether or not the ticket is a normal ticket (step 238) and whether or not the ticket is within the boarding section and within the validity period (step 236). Step 242).

Here, a normal ticket is an abnormal ticket, that is, a ticket that has already been scrapped by a ticket issuing machine (cancelled ticket), a used ticket that has been scrapped (a ticket collected by a ticket gate), an unencoded ticket ( A blank ticket), a ticket other than a ticket whose recorded contents have been erased by approaching a magnet or the like.

If the ticket is not a normal ticket (NO in step 238), it is checked whether the ticket is a revoked ticket (step 240).

This is for discriminating whether an abnormal ticket is a discarded ticket or a ticket whose recorded content has been erased by approaching another unencoded ticket or a magnet.

Here, as described above, tickets that have already been discarded (cancelled tickets) and used tickets that have been discarded (tickets collected by automatic ticket gates) are treated as discarded tickets. Become.

That is, if the ticket is discarded, only the clock pulse is left and the other data tracks are erased, so that it can be distinguished from other abnormal tickets without pulses.

In this manner, when it is determined that the ticket is a revoked ticket in step 240 (YES in step 240), the gates 41A and 41B are closed, the revoked ticket lamp 44 is turned on, and at the same time, the revoked ticket is collected and an alarm is issued. (Steps 228, 23
0,232,234).

This will reveal the fraudulent behavior of the user of the waste ticket.

On the other hand, if the ticket detected as an abnormal ticket is other than a discarded ticket (NO in step 240), the processing of steps 220 to 226 is performed, the gates 41A and 41B are closed, and the detected abnormal ticket is Is released, and the reading error lamp 43 is turned on.

As described above, in this embodiment, even if the same act of using an abnormal ticket is used, an unencoded ticket (blank note) not magnetically recorded, a ticket erased by bringing a magnet or the like close thereto, and a used ticket The use of discarded tickets is particularly effectively prohibited.

By the way, when it is determined in step 238 that the taken ticket is a normal ticket (YES in step 238), it is confirmed that the ticket is in the section and within the validity period ( (YES in step 242), the departure station code is written, and gates 41A and 41B are opened (steps 244 and 246).
The entrance of the ticket submitter is permitted, and either the adult normal ticket lamp 45 or the child normal ticket lamp 46 is turned on.

Then, when the passenger passes, the gate is closed again and the system waits for visitors (steps 254, 256, 258).

On the other hand, if it is determined in step 242 that the captured ticket is not within the section or within the validity period (NO in step 242), the gate is immediately closed (step 21).
0), the section / date overlamp 42 is turned on, the ticket is released, and a warning such as section over is issued (steps 212, 214, 216).

Thus, the boarding of a ticket holder outside the boarding section or a ticket holder whose validity period has expired is rejected.

Next, a case where a person who has entered through the automatic ticket gate 40 as described above leaves at the arrival station will be described.

In this case, the passenger inserts the ticket into the exit-side card insertion slot 48, so the determination result in step 202 is NO, and then it is determined whether the captured ticket is a normal ticket (step 20).
4,206).

Here, in the case of a normal ticket (YES in step 206), it is further checked whether the ticket is within the boarding section or within the validity period (step 208). And the gate is opened (step 24).
8), the ticket is scrapped and collected (steps 250 and 252).

In this scrap ticket processing, as in the first embodiment method,
This is done by leaving only the clock pulse track magnetically recorded on the ticket and erasing all other data tracks (see FIG. 4 (a)).

As described above, in this embodiment, all used tickets are discarded, so that subsequent unauthorized use can be reliably prevented.

Then, after the passenger passes, the date is closed and the next time is prepared (steps 254, 256, 258).

On the other hand, when the inspection at step 208 determines that the ticket is not within the section or within the validity period (step 20).
(NO at 8), the gate is closed (step 210), and the exit of the passenger is denied.

Then, the period / date overlamp 42 is turned on, the ticket is released, and a warning such as a section over is issued (steps 212, 214, 216).

On the other hand, if it is determined in step 206 that the captured ticket is not a normal ticket (NO in step 206), subsequently, it is determined whether the ticket is a discarded ticket or another abnormal ticket (step 206). 218).

If it is determined that the ticket is abandoned (YE
S), Steps 228 to 234 are performed, the gate is closed, the waste ticket lamp is turned on, and the ticket is collected.

If it is determined that the ticket is an abnormal ticket other than a discarded ticket (NO in step 218), the processing in steps 220 to 226 is performed, the gate is closed, the reading error lamp 43 is turned on, and the ticket is released. become.

In the second embodiment, as described above, first, it is determined whether or not the captured ticket is a normal ticket. If the ticket is determined to be normal at the entrance side, the departure station is written and the passenger enters as it is. At the same time, if the exit side determines that the ticket is a normal ticket, a scrap ticket process is performed in which only the clock pulse track of the entrance ticket is left and other data tracks are deleted.

Therefore, the subsequent use of the used ticket can be reliably prevented.

On the other hand, if it is determined that the taken ticket is not a normal ticket, a check is made as to whether the ticket is a discarded ticket or another abnormal ticket.

For this reason, unauthorized use of a used ticket or the like can be reliably prevented.

On the other hand, in the case of an abnormal ticket other than a discarded ticket, the reading error lamp is turned on and the ticket is released, so that the use of an unencoded ticket or the like can be prevented.
