[SUMMARY OF THE INVENTION] However, the ticket data recording unit to correspond exactly to the magnetic data processing unit, the order is processed, the time of initial setting of the number of redundant bits, to record the number of redundant bits for the test However, although the correction is based on this and the initial setting is made to the optimum number of redundant bits, in order to make this ticket data processing unit correspond to the magnetic data processing unit with high accuracy, the reliability is required only by one correction. Since it is low and uncertain, it is necessary to repeat the operation of correcting the number of redundant bits several times to perform initial setting. As a result, there is a problem that it takes time to initialize the number of redundant bits.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a magnetic ticket redundant bit setting apparatus which can correct the number of redundant bits for data positioning setting recorded on a magnetic ticket in a short period of time and can initialize it.

According to the present invention, when the number of redundant bits is initialized, the high-density redundant bit recording control means records the test redundant bits at a high-density interval smaller than the normal bit interval of the redundant bits. The number of high-density redundant bits recorded by the control means is counted to obtain the normal number of redundant bits.
It is determined whether or not the number of corresponding normal high-density redundant bits.
When the normal high-density redundant bit number is not the normal high-density redundant bit number, a redundant bit correction value to be corrected to the normal high-density redundant bit number is obtained, and the normal redundant bit is corrected and output.

[0007]

As described above, at the time of initial setting of the number of redundant bits, it is easy to record the redundant bits for testing by using fine and high-density redundant bits narrower than the regular bit interval as correction standards. , High-precision correspondence can be taken, a reliable and reliable initial setting can be performed with a single correction, and therefore initial setting can be performed in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawing shows a magnetic ticket redundant bit setting device for initially setting the number of redundant bits of a magnetic ticket used in an automatic ticket gate. In FIG. A start detection sensor S disposed on the start end side of the main transport path 11
, A read head 13, a main transport path 11, and a discharge transport path 14 and a recovery transport path 15 branched and connected to the end side of the main transport path 11. Each of the transport paths 11, 1 described above
The transport members 4 and 15 are driven by a transport motor M such as transport rollers 16 for nipping and transporting the tickets, and transport the tickets guided in a predetermined direction. Also, the discharge conveyance path 1
A flapper f is provided at a branch position between the collecting path 4 and the collecting and conveying path 15, and the ticket conveyed from the main conveying path 11 is sorted to the discharging side or the collecting side by the sorting action of the flapper f. The write head 12 is provided for writing redundant bits and ticket data, and a high-density redundant bit or a regular redundant bit with a reduced bit interval is provided on a magnetic surface of the ticket guided to the main transport path 11. A predetermined magnetic data as a ticket is written. The read head 13 is also provided for reading redundant bits and ticket data, and reads predetermined magnetic data as a magnetic ticket written by the write head 12. Magnetic tickets such as tickets, coupons, and commuter passes are used as tickets handled in this transport processing system, and FIG. 2 shows a case where the position of a ticket data recording unit recorded on the magnetic ticket is initially set. As described above, before the ticket data recording section 22 of the ticket 21, the test high-density redundant bits 23 are recorded at a high-density interval considerably smaller than the regular bit interval, and the fine high-density redundant bits 23 are recorded. Used as a correction standard. As a result, high-precision correspondence can be easily achieved with a high-density bit interval, and initial setting can be performed by one correction.

FIG. 3 is a block diagram showing a control circuit of a redundant bit setting device for a magnetic ticket. A CPU 31 controls each circuit device according to a program stored in a ROM 32, and its control data is stored in a RAM 33 in a readable manner. I do. C
The PU 31 counts the number of high-density redundant bits 23 recorded on the test magnetic ticket 21 at the time of initial setting of the redundant bits, and determines a normal number of bits corresponding to the normal number of redundant bits.
Judge whether or not the number of high-density redundant bits
If the number of bits is not long, a redundant bit correction value for correcting to a normal high-density redundant bit number is obtained. cure.

As a result, the ticket data recording section 22 recorded on the magnetic ticket 21 accurately corresponds to the write head 12 and the read head 13 facing the fixed position on the main transport path 11 for constant-speed transport. When the start detection sensor S detects the number of high-density redundant bits 23, the PCT timer (positive characteristic thermistor timer) T counts a start timer value according to the detection signal.

The processing operation of the magnetic ticket redundant bit setting device thus constructed will be described with reference to the flowchart of FIG. Now, the number of redundant bits of the magnetic ticket initially set at the time of ticket processing adjustment of the automatic ticket gate is determined by first guiding the test magnetic ticket 21 to the main transport path 11, and writing the ticket on the ticket surface by the write head 12 in this transport process. For example, high-density redundant bits 23 having a magnetic density of four times are recorded (step n1). Further, reading the number of bits of the recorded high density redundant bit 23 in the read head 13, which more that CPU31 counts the number of high density redundant bits of the normal to be a reference and the ratio
Comparison and determination to determine a redundant bit correction value for correcting to the normal number of high density redundant bits (steps n2 to n3).
). Based on the obtained redundant bit correction value, the magnetic ticket 21 is reversely conveyed, then forwarded again, and rewritten on the surface of the ticket at regular redundant bit intervals by the write head 12, so that one ticket can be used. High-precision redundant bits can be written, and the written redundant bits are read and confirmed by the read head 13 to complete the initial setting (steps n4 to n6).
).

As described above, at the time of initial setting of the number of redundant bits, the test redundant bits can be easily written by using fine and high-density redundant bits narrower than the regular bit interval as correction standards. High-precision correspondence can be taken, and reliable initial settings can be made with a single correction.
Therefore, it can be set in a short time.

In the correspondence between the present invention and the configuration of the above-described embodiment, the ticket transport path of the present invention corresponds to the main transport path 11 of the embodiment, and similarly, the magnetic data processing section includes a write head. Corresponding to 12 and read head 13, the magnetic ticket is
The magnetic ticket 21 corresponds to the ticket data, the ticket data corresponds to the ticket data recording section 22, and the high-density redundant bit recording control means and control means correspond to the CPU 31. However, the present invention is not limited to this.
