Description

Description: TECHNICAL FIELD The present invention relates to a toll road toll collection system, and in particular, to increase the magnetic recording capacity of a magnetic card type toll ticket even when existing magnetic card type terminals are mixed. The present invention relates to a magnetic recording conversion method for making it possible.

<Prior Art> On long-distance toll roads and the like in which an entrance gate and an exit gate are scattered at a plurality of places, a toll system that collects a toll according to a use section and a use vehicle type is adopted. Therefore, at such an entrance gate on a toll road, etc., in addition to printing the type of the vehicle, the date and time of use, or the entrance gate information such as the name of the entrance gate, a toll ticket magnetically recorded and issued to the user is passed to the user. A toll collection system is adopted in which a toll collection member collects the toll ticket from the user at a gate, reads information magnetically recorded on the toll ticket, and adjusts the usage fee.

For this reason, terminals for processing cards such as a highway card which is a toll ticket or a prepaid card and a credit card called a separate payment plate are installed at the entrance gate and the exit gate of the above-mentioned toll road. ing.

FIG. 11 shows an example of a magnetic card-type pass ticket MC. In the figure, MS is a magnetic stripe, on which magnetic recording is performed with one wide track. In current terminals, the recording density is 100 BPI (bits per inch), and the recording method is the FM method. In addition, in the terminal at the entrance gate, one track is divided into three areas MS1, MS2, and MS3 in the track length direction to back up the recorded contents, and the same entrance gate information is recorded in each area. Then, at the terminal of the exit gate, after reading the entrance gate information, in addition to the entrance gate information, a fee,
The exit gate information such as the exit gate name and the date and time is overwritten and recorded in any area, and the recorded information is read to confirm whether or not the information was correctly recorded.

<Problems to be Solved by the Invention> In the future, the amount of information to be recorded at the exit gate tends to increase, for example, due to the possibility that the payment by credit card will be settled.
With the PI recording method, the capacity becomes insufficient.

Therefore, it is necessary to increase the recording capacity, but it is not practical to replace all the terminals at all gates of a certain toll road with a new model having a large recording capacity at one time because it stops traffic temporarily. . Therefore, the terminal will be gradually replaced with a new terminal from the exit gate side. In this case, it is acceptable to mix the existing magnetic card type terminal (hereinafter referred to as the current terminal) with the new terminal. There is a need for a magnetic recording conversion method that can.

An object of the present invention is to provide a magnetic recording conversion method for a toll road ticket that meets such a demand.

<Means for Solving the Problems> A method according to the first invention uses a read head and a write head for one track for a magnetic stripe of a toll ticket,
Read the low bit density information already recorded on the passport with the read head, and write back the information on the same passport with the write head at a higher bit density than the recorded information,
It is characterized in that the recorded content of the rewritten information is read by a reading head and confirmed.

The method according to the second invention uses a plurality of tracks of read heads and write heads for a magnetic stripe of a pass ticket, reads information of one track already recorded on the pass ticket with at least one read head, and reads the same information. The information is written back over a plurality of tracks by a plurality of write heads on the toll ticket, and the recorded content of the rewritten information is read by a plurality of read heads for confirmation.

The method according to the third invention is characterized in that, in the second invention, the recording density of the recorded information is low bit density, and the information is written back at a higher bit density than the recorded information. .

The method according to the fourth invention is the method according to the first or second or third aspect.
The present invention is characterized in that, while the recorded information is recorded by the FM method, the information is written back by the MFM method.

<Operation> In the first invention, one track is formed on the magnetic stripe of the toll ticket as in the current machine, but information recorded in advance at a low bit density is read and the same To write back information. Therefore, the writing bit density is higher than that of the current device, and the recording capacity is increased accordingly. In this case, even if the entrance gate information is recorded at a low bit density of 100 BPI by the current machine at the entrance gate,
Since the reading can be directly performed by the reading head, there is no problem in the reading process at the exit gate.

In the second invention, unlike the current machine, two or more tracks are formed on the magnetic stripe of the pass ticket. Then, the information recorded in one track is read in advance, and the information is written back to the same passport over a plurality of tracks. Therefore, even if the write bit density is the same as that of the current device, the recording capacity increases due to the large number of tracks. Further, in this case, even if the entrance gate information is recorded on one track by the current machine at the entrance gate, it can be read by any of a plurality of read heads, so that there is no problem in the reading process at the exit gate. .

In the third invention, when new information is recorded on a plurality of tracks in the second invention, the write bit density is higher than that of the current machine, and the recording capacity is further increased.

In the fourth invention, by performing writing using the MFM (Modified FM) method, the bit density is doubled even if the fci (flux change per inch) is the same as in the case of 100 BPI using the current FM method. 200 BPI, and the recording capacity increases accordingly. If the fci is the same, the write head of the current machine can be used.

If an abnormality is detected in step B19, the process proceeds to step B19, where it is determined that recording is abnormal.In step B20, the switching flapper 142 is switched to the hopper stacker 102 side, and in step B21, the abnormal traffic is performed. The ticket 104 is collected in the hopper stacker 102. After the optical sensor 147 detects the passing of the abnormal passport 104, the process returns to the step B3.

As described above, by temporarily holding the normal passport 104 in the standby unit 117 in advance, the passport 104 can be issued in a very short time after the push button for selecting the vehicle type is operated.

The processing mode of the passport processing unit 100 is one of an entrance gate, an exit gate, a check barrier, and a transit ticket issuance gate. This is achieved by a command to the control unit 3.

As shown in FIG. 10 showing the schematic structure of the card processing unit 200, the card processing unit 200 may be a prepaid card other than the above-mentioned toll ticket 104, a highway card, a credit card, a separate payment plate or an IC card. The card processing is performed collectively.

In the card processing unit 200, a transfer line is formed in a straight line from the entrance 201 to the rear end of the housing 202. Inside the housing 202, a card type sensor 203 for detecting the type of the card in order from the entrance 201 along the transport line, and a thermal printing head for recording necessary information for a printable card such as a highway card. 204
A reproducing head 205 that reads magnetic information of a magnetic recording unit (not shown) formed on a card such as a credit card,
Recording head for writing new magnetic information to this magnetic recording unit
206 and a reading electrode 207 for reading information recorded on a card such as an IC card are provided.

A plurality of drive rollers 208 to 215 for reciprocating the card along the transport line are rotatably attached to the housing 202 at intervals shorter than the length of the card. A pressing roller 216 is in contact with the thermal print head 207, and the drive rollers 213 and 214 are opposed to the reproducing head 205 and the recording head 206 with a transport line interposed therebetween. A holding member 217 opposed to the holding member 217 is disposed therebetween. Doorway 2
Drive roller 20 located between 01 and thermal print head 204
In FIG. 8, 209 and in FIG. 6, pinch rollers 218 rotatably mounted on the housing 202 are in contact with drive rollers 212 and 215 located on both sides of the drive rollers 213 and 214, respectively, with the conveyance line interposed therebetween.

The drive rollers 208 to 215 are configured to rotate synchronously via timing belts 220 to 222 by a forward / reverse rotatable pulse motor 219 installed below the reproducing head 205 and the recording head 206, respectively. These pulse motor 219, thermal printing head 204 or reproducing head 205
The operation of the recording head 206, the reading electrode 207, and the like is controlled by the processing control unit 3 based on a detection signal from the card type sensor 203 and the like.

 Note that reference numeral 224 in the drawing denotes a tension roller.

Therefore, when the collection staff inserts the card received from the road user into the entrance 201 at the time of toll settlement, the pulse motor 219
Rotates forward and pulls the card into the housing 202, and when the card type sensor 203 detects this as a highway card, reads the current balance with the reproducing head 205,
After outputting this to the processing control unit 3 incorporated in the main body 2, the current usage fee is settled, and the balance and the like are written on the highway card by the recording head 206. Thereafter, the pulse motor 219 rotates in a reverse direction to send out the highway card to the entrance 201, and in the middle thereof, the above-described processing is confirmed by the reproducing head 205 as necessary, and the above-described balance and the like are printed by the thermal printing head 204 as necessary.

If the card type sensor 203 detects that the card is a credit card such as a separate payment plate, the reproducing head 2
At 05, the information recorded on the credit card is read and output to the processing control section 3, after which the pulse motor 219 rotates in the reverse direction and sends the highway card to the entrance 201. In addition, in the case of an IC card, I
Transport the C card and read the information recorded here,
After outputting this to the processing control unit 3, the pulse motor 21
9 is reversed and the IC card is sent out to the entrance 201.

<Effects of the Invention> According to the present invention, it is possible to increase the recording capacity of a toll ticket even when a current terminal and a new terminal are mixed.
