BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic ticket used for, for example, an automatic ticket gate, and more particularly to a magnetic ticket for accurately matching magnetic data of the magnetic ticket with a magnetic data processing section of the automatic ticket gate. The present invention relates to a redundant bit setting device for a ticket.

[0002]

2. Description of the Related Art Tickets generally used in automatic ticket gates,
As shown in FIG. 5, a magnetic ticket such as a coupon ticket or a commuter ticket has redundant bits 53 recorded at regular intervals in front of the ticket data recording section 52 of the magnetic ticket 51, and the number of redundant bits 53 is used as a start detection sensor. Based on the detection by 54 to obtain the start timer value, the ticket data recording unit 52 recorded on the magnetic ticket 51 is made to correspond to the transportation speed of the ticket to correspond to the magnetic data processing unit provided on the ticket transportation path. Then, the magnetic data is processed.

However, in order to accurately correspond the ticket data recording section to the magnetic data processing section, the redundant bit number for testing is recorded when the redundant bit number is initially set, and this is used as a reference. However, in order to make this ticket data processing unit correspond to the magnetic data processing unit with high accuracy, it is unreliable and uncertain with just one correction. However, it is necessary to repeat the correction operation of the redundant bit number several times to perform the initial setting, and as a result, there is a problem that it takes time to initialize the redundant bit number.

Therefore, an object of the present invention is to provide a redundant bit setting device for a magnetic ticket, in which the number of redundant bits for setting data positioning recorded on a magnetic ticket can be corrected and initialized in a short time.

SUMMARY OF THE INVENTION The present invention is a magnetic data processing system in which ticket data recorded on a magnetic ticket is placed on a ticket conveying path, based on counting the number of redundant bits recorded on the magnetic ticket. A redundant bit setting device for a magnetic ticket for magnetic data processing corresponding to a unit, and a high density redundant bit recording control means for recording redundant bits for testing at a high density interval narrower than a regular bit interval of the redundant bits. And, based on counting the number of high density redundant bits recorded by the high density redundant bit recording control means, a redundant bit correction value for correcting to a normal redundant bit number is obtained and corrected output to a normal redundant bit. And a control means for controlling the operation.

[0006]

According to the present invention, when the number of redundant bits is initialized, the high density redundant bit recording control means records the redundant bits for testing at a high density interval narrower than the regular bit interval of the redundant bits, and further, Based on counting the number of high-density redundant bits recorded by the control means, the control means obtains a redundant bit correction value for correcting to the regular redundant bit number and correctively outputs the redundant bit.

[0007]

As described above, at the time of initial setting of the number of redundant bits, the redundant bits for testing are recorded by using the fine and high-density redundant bits which are narrower than the regular bit interval as the correction reference, which facilitates the recording. Can be handled with high accuracy, and highly reliable and reliable initial setting can be performed with one correction, and therefore initial setting can be performed in a short time.

A predetermined magnetic data as a ticket is written and processed. The read head 13 is also provided to read redundant bits and ticket data, and reads predetermined magnetic data written by the write head 12 as a magnetic ticket. Magnetic tickets such as tickets, coupon tickets, commuter tickets, etc. are used as the tickets handled by this transportation processing system, and when the position of the ticket data recording section recorded on this magnetic ticket is initialized, it is shown in FIG. As described above, in front of the ticket data recording unit 22 of the boarding ticket 21, the high-density redundant bits 23 for testing having a high-density interval which is considerably narrower than the regular bit interval are recorded, and the fine high-density redundant bits 23 are recorded. Used as a correction standard. As a result, it is possible to easily take a highly accurate correspondence due to the high-density bit interval, and the initial setting can be performed with one correction.

FIG. 3 is a block diagram of a control circuit of a redundant bit setting device for a magnetic ticket. The CPU 31 controls each circuit device according to a program stored in the ROM 32, and the control data is readablely stored in the RAM 33. To do. C
The PU 31 counts the number of the high-density redundant bits 23 recorded on the test magnetic ticket 21 at the time of initializing the redundant bits, and based on this, the redundant bit correction value for correcting to the regular redundant bit number. Based on this redundant bit correction value, correction output is performed so as to obtain a regular redundant bit, and the writing head 12 rewrites.

When the start detection sensor S detects the number of high-density redundant bits 23, the PCT timer (positive characteristic thermistor timer) T measures the start timer value according to the detection signal.

The processing operation of the thus configured redundant bit setting device for a magnetic ticket will be described with reference to the flowchart of FIG. Now, the redundant bit number of the magnetic ticket initially set at the time of ticket processing adjustment of the automatic ticket gate is to first guide the test magnetic ticket 21 to the main transport path 11, and in this transport process, by the writing head 12 on the ticket surface, For example, a high-density redundant bit 23 having a magnetic density four times is recorded (step n1). Further, the read head 13 reads the number of recorded high-density redundant bits 23, and the CPU 31 counts the number of redundant high-density bits 23 to obtain a redundant bit correction value for correcting the number of normal redundant bits (steps n2 to n3).
