[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ticket issuing device for station service.

[0002]

2. Description of the Related Art In this type of ticket issuing apparatus, a long sheet of paper wound on a roll, that is, a so-called roll paper is fed out and its tip is cut into a ticket-sized rectangular shape, and the cut ticket paper is conveyed by a conveying means. However, the data is magnetically recorded while forming the data track along the conveying direction on the paper sheet being conveyed.

The longitudinal length of the cut paper sheet corresponds to the width of the roll paper, and the data tracks formed on the paper sheet are formed along the longitudinal direction of the paper sheet. If the rolled-out rolled-out paper is cut, the short-side direction of the paper sheet corresponds to the conveying direction, and it is impossible to form the data track along the longitudinal direction of the paper sheet as it is.

Therefore, a mechanism for rotating the paper sheets by 90 degrees is provided in the conveying path. With this mechanism, the longitudinal direction of the paper sheet is in a state of being along the transport direction, and thus it is possible to form the data track along the longitudinal direction of the paper sheet.

A so-called jitter check is also performed on the magnetic recording on the ticket. This jitter check is for reading a data signal from a ticket and confirming whether the period of the data signal is within a certain range, and is used for device management such as speed adjustment of a transport system.

[0006]

The paper sheet cut from the roll paper may be conveyed in a state of being exactly rotated by 90 degrees. However, in actuality, the rotation is caused by misalignment between the conveying system and the paper sheet. There is a case where the paper sheet is tilted, that is, skewed, such as not reaching 90 degrees or exceeding 90 degrees. Fluctuations in temperature and humidity are also causes of skew.

When the magnetic recording is performed on the ticket as it is, the data tracks formed on the ticket cannot be kept parallel to the longitudinal direction of the ticket. In this case, a reading error will occur when using the ticket after it is issued.

Further, the conventional jitter check is a simple process for determining whether or not the period of the data signal is within a certain range, and is insufficient as a device management.

Has been. The discarding transport path 19 is provided with a punching portion 21 for punching a waste ticket.
A scrap ticket box 22 is provided on the discharge side of 9.

Further, first and second drive motors 31, 32 are arranged in the apparatus main body 1. The first drive motor 31 rotationally drives the feed roller 4 and the first transport roller pair 5, and the second drive motor 32 drives the second transport roller pair 5 and the platen roller 9 in the thermal head 9.
a, the third to fifth conveying roller pairs 13a to 13c, and the conveying belt 18 in each of the writing and reading magnetic heads 15 and 16 are rotationally driven.

The drive of the first and second drive motors 31, 32 is controlled by the control unit 40.
That is, the leading end of the roll paper 2 conveyed by the rotation of the first and second conveying roller pairs 5 and 6 is located at the thermal head 9
When the sensor 10 passes through and is detected by the sensor 10, the driving is stopped.

Here, the ticket issuing operation will be described.
First, the roll paper 2 is set in the loading unit 2A, the leading end of the roll paper 2 is pulled out, the feed roller 4 is stretched, and the feed roller 4 is rotated to feed it. This rolled-out roll paper 2 is sent along the transport path 3 by the rotation of the first and second transport roller pairs 5 and 6, and when the leading end portion is detected by the sensor 10, the feed roller 4 and the first roll paper are fed. And the second
The rotation of the pair of transport rollers 5 and 6 is stopped. With this stop, the roll paper 2 is stopped at the fixed position.

The stopped roll paper 2 is cut at its leading end (the leading end has a great variation in shape so that a paper sheet cannot be formed) by the operation of the second cutter unit 8, and the transport path 3 and the waste paper are discarded. Waste ticket box 2 via the transport path 19
Discarded in 2. At this time, the paper edge of the roller paper 2 is
It is conveyed and stopped so as to be positioned between the thermal head 9 and the platen roller 9a facing the thermal head 9. When issuing a ticket, the roll paper 2 stopped at this position is cut with a ticket length of 30 mm by the second cutting unit 8, and the commuter ticket (85 mm) or the green ticket (12
0 mm) or the like is cut by the first cutting portion 7 as described later.

The paper sheets cut by the first or second cutting portions 7 and 8 are the thermal head 9 and the platen roller 9a.
And various information such as a station name, a section, and a fee are printed on the front side (printed portion). After being printed in this manner, the ticket paper is sent to the write magnetic head 15 and information is magnetically recorded on the back side (magnetically recorded portion) thereof, and then sent to the read magnetic head 16 for magnetic recording. The information is read and the content is confirmed.

If the result of the confirmation by the magnetic reading head 16 is correct, the paper sheet is conveyed to the paper sheet outlet 11 and discharged. If the result of the confirmation by the magnetic reading head 8 is incorrect, the ticket passes through the gate 20 and the waste transport path 1
After being sent to the printer 9 and punched by the punching unit 21, the bills are collected as scrapped bills in the scrap ticket box 22.

In the case of processing an old ticket for refund or cancellation, the old ticket is inserted through the slot 23, the magnetic information is read by the read magnetic head 16, and then the write magnetic head is read if necessary. Rewriting (or demagnetization) of magnetism by 15
After that, it is perforated by the perforation unit 21 through the discarding conveyance path 19 and collected in the scrap ticket box 22.

By the way, the paper sheets cut by the cutters 7, 8 are rectangular and the length in the longitudinal direction corresponds to the width of the roll paper 2, and the writing magnetic head 15 forms the paper sheets on the paper sheets. The data track is formed along the longitudinal direction of the ticket. If the rolled-out roll paper 2 that has been fed out is cut, the short side direction of the paper sheet corresponds to the conveyance direction, and it is impossible to form a data track along the longitudinal direction of the paper sheet as it is.

Therefore, a mechanism for rotating the paper sheet by 90 degrees is constituted mainly by the conveying roller pairs 13a to 13c on the downstream side of the thermal head 9. A specific example of this is shown in FIG. An L-shaped rotating action plate 50 is provided on the downstream side of the roller pair 13a. The rotation acting plate 50 includes a short side wall having a length of about half the width of the conveying path 3 and a long side wall longer than the short side wall, and the short side wall is in the conveying direction of the conveying path 3. Is arranged so that the long side wall is orthogonal to the direction of the conveyance path 3 along the conveyance direction.

The main part of the control circuit is shown in FIG. ROM 6 for storing programs in CPU 60 that controls the entire apparatus
1, a RAM 62 for temporary storage, a mechanical control unit 63 that controls a mechanical unit such as a transport system, a demodulation circuit 64, a skew detection circuit 65, and a jitter measurement circuit 66 are connected.

The data signal read by the read magnetic head 16 is amplified to a sufficient level by the amplifier 67 and supplied to the demodulation circuit 64. The demodulation circuit 64 restores "1" and "0" data from the data signal. The restored data is stored in the RAM 62 and subjected to appropriate processing.

The output of the amplifier 67 is the skew detection circuit 65.
And a jitter measuring circuit 66. The skew detection circuit 65 detects the skew of the paper sheet after being rotated by 90 degrees based on the phase difference between the signals corresponding to the edge portions of the paper among the data signals read from each data track by the read magnetic head 16. The detection result is sent to the CPU 60 and appropriate processing is executed.

The jitter measuring circuit 66 detects the period of the data signal read by the read magnetic head 16. The detection result is stored in the RAM 62 as device management data.

As shown in FIG. 4, the jitter measuring circuit 66 comprises a control section 71, a counter 72, an oscillator 73 and a register 74. The control unit 71 detects the rise of the output of the amplifier 67, loads the count value of the counter 72 into the register 74 at the detection timing, and the counter 7
The count value of 2 is initialized to zero. The counter 72 counts the reference clock signal emitted from the oscillator 73. The value of the register 74 corresponds to the cycle of the data signal. Note that the value of the register 74 loaded first is invalid, and the actual measurement starts from the second rising edge of the data signal.

Next, the operation of the above configuration will be described with reference to the flowchart of FIG. The length of the ticket paper 2a cut from the roll paper 2 in the longitudinal direction corresponds to the width of the roll paper 2, and as shown in FIG. 1, the ticket paper 2a is conveyed in the cut state and fed by the roller pair 13a. Is brought into contact with the short side wall of the rotating action plate 50. The paper sheet 2a, which is in contact with the short side wall of the rotation action plate 50, is rotated by 90 degrees in the direction of the arrow in the figure by the feeding action of the roller pair 13b, and the longitudinal direction is in the state of being along the conveying direction. . When the ticket is rotated, the roller pair 13a moves downward at a predetermined timing, and the roller pair 13a is hidden from the transport surface of the transport path 3. This is to prevent the presence of the roller pair 13a from interfering with the transportation of the rolled paper sheet.

The rotated paper sheet is in a state where its longitudinal direction is along the conveying direction, and is sent to the write magnetic head 15 as it is under the feeding action of the roller pairs 13b and 13c. And
The write magnetic head 15 magnetically records data while forming a plurality of data tracks on the paper sheet along the transport direction.

However, the paper sheet cut from the roll paper 2 may be conveyed in a state of being exactly rotated by 90 degrees, but in reality, the rotation becomes 90 degrees due to the engagement deviation between the conveying system and the paper sheet. It does not reach, or it exceeds 90 degrees,
There is a case in which a so-called skew occurs on the paper sheet.

If the magnetic recording is performed on the ticket as it is, the data tracks formed on the ticket cannot be kept parallel to the longitudinal direction of the ticket. In this case, a reading error will occur when using the ticket after it is issued.

Therefore, ticket issuing is started by feeding the roll paper 2 and cutting the leading end of the roll paper 2 (step 101).
) Then, skew detection is performed on the paper sheet after being rotated by 90 degrees (step 102).

In this skew detection, as shown in FIG. 6, among the data signals read from the data tracks Atr, Btr, Ctr on the ticket 2a, the lowest data track A is selected.
The data signal of tr and the data signal of the uppermost data track Ctr are selected. Then, the rising edge signal corresponding to the ticket edge portion of the data signal of the data track Atr and the rising edge signal corresponding to the ticket edge portion of the data signal of the data track Ctr are slices for skew detection lower than the normal slice level. Each is detected by the level, and the phase difference Tac of both signals is measured. This phase difference Tac directly corresponds to the skew of the ticket 2a.

If the phase difference Tac, that is, the skew is equal to or larger than the predetermined value (NO in step 104), the ticket paper 2a is sent to the punching section 21 to form punch holes as error notes (step 105). At the same time, the transport system is controlled so that the skew is eliminated. This is so-called skew adjustment (step 107). For example, the roller pair 13a when rotating the ticket
Adjustments such as advancing or delaying the evacuation timing from the ticket transport surface are made. Alternatively, adjustment is made such that the rotation speed of the roller pair 13b, which is the driving force for rotation, is increased or decreased. Alternatively, the ticket 2a may be the rotating action plate 50.
The conveyance speed until it comes into contact with is adjusted.

Despite the adjustment, the ticket issuing process may continue without the skew being eliminated. When the number of times the ticketing process is retried reaches a predetermined value or more, it is determined that there is an abnormality and the apparatus is stopped (step 108).

Thus, by detecting the skew caused by the rotation of the paper sheet 2a and adjusting the skew when the skew is not more than the predetermined value, the magnetic recording on the paper sheet 2a can be properly maintained. . Therefore, it is possible to prevent a reading error when using the ticket after issuing the ticket.

By the way, along with the skew detection, the jitter measurement is performed (step 103). That is,
As shown in FIG. 7, the waveform of the data signal output from the amplifier 67 has two types: a long period T and a short period T / 2. Actually, the cycle T and the cycle T / 2 vary due to variations in machines, variations in transport speed, and the like, resulting in jitter.

The variation degree of the period T and the period T / 2 is measured by the jitter measuring circuit 66. Since this measurement result is not a range determination but an absolute value measurement, it can be appropriately used for device management by appropriately confirming the cycle condition of the data signal, stored in the RAM 62, and stored as necessary. Used. For example, it can contribute to confirmation of the reading margin of ticket data and facilitation of machine adjustment. On the other hand, the stable operation of the carrier system is indispensable as a requirement for properly performing magnetic recording on the ticket paper 2a while being able to properly confirm the cycle condition of the data signal and being highly applicable to device management. . If an error occurs when the belt is wound around each roller at the manufacturing stage, stable operation of the transport system becomes impossible and the accuracy of magnetic recording is impaired.

In order to prevent such a problem, the belt is colored, and the belt is managed by different colors. Also, if necessary, the roller on which the belt is hung has the same color as the belt, which greatly reduces the chance of error.
