[0002]

2. Description of the Related Art In recent years, automatic ticket gates have been installed at entrances and exits of facilities such as stations for the purpose of labor saving in railways. This automatic ticket gate device takes in and inspects the ticket carried by the user when entering or exiting the facility or when changing trains at the facility, and the result of this inspection indicates that the ticket is appropriate. For example, it allows the passage of users, and blocks the passage of users if inappropriate.

This automatic ticket gate device reads magnetic information (for example, an entrance station and a valid fare) recorded on one side (back side) of a ticket inserted by a user at the time of entrance, exit or transfer. Based on this read information, the permission or blocking of the passage of the user is determined.

In recent years, ticket gates of various sizes have been handled by automatic ticket gates. For example, a narrow one (normal ticket size) or a wide one (commuter pass size) is used. As a commuter pass of this commuter pass size, a stored fair (SF) type train ticket (SF card) that reduces the value every time it is used in advance with a monetary value is used. Is a processing unit that sorts out various tickets and processes each of them, for example, an SF processing unit that performs printing and reduction punching processing on an SF card such as an entrance station, and scissors punching processing such as a coupon ticket and an ordinary ticket. A scissors punch section is provided. The SF processing unit is provided with a printing mechanism for performing printing processing on the SF card conveyed on the conveyance path. By passing the SF card through the printing mechanism at a constant speed, the printing quality such as the name of the entrance station can be improved. Are to be retained.

This printing mechanism includes a thermal head and an SF provided at a predetermined distance from the thermal head.
It consists of a platen roller for card feeding, and when an SF card is loaded between them, the platen roller is rotated while the SF card is sandwiched between the thermal heads by the platen roller, and the frictional force causes the SF card to rotate.
The card is sent and the entrance station name etc. is printed on the printing surface of the SF card. In this printing mechanism, S
In order to keep the print quality of characters such as the name of the entrance station on the F card at a predetermined level, the platen roller is rotated so that the force that presses the SF card against the thermal head becomes constant, and the SF card is rotated at a constant speed by the frictional force.

In addition to the cost reduction effect, the overall size of the device can be reduced.

The normal ticket processing operation by this automatic ticket gate apparatus will now be described.

In this automatic ticket gate apparatus, when the ticket 2 is inserted through the slot 3, usually the detectors 6 and 7 detect the size in the width direction, and the detection result is passed through the ticket detection circuit 54. It is taken in by the CPU 42. The ticket 2 as it is is conveyed through the conveying path 5 regardless of the front and back, and magnetic information is read by either one of the reading heads 10 and 11 provided one by one, and the magnetic information is read by the reading circuit 50 to the CPU 42. It is captured.
At this time, the CPU 42 obtains information on which side of the inserted ticket 2 is up by the read head 10 or the read head 11 that has read the magnetic information. C
The PU 42 allows the boarding ticket 2 to pass as it is or performs magnetic processing based on the captured information. For example, when magnetic processing is performed, the magnetic information is written on the back surface of the ticket 2 by either one of the write heads 12 and 13 provided one by one, and the write results are provided by the read head 1 provided one by one.
Read and confirm with either one of 4 and 15. Then, the CPU 42 reduces the value of the ticket 2 each time it is used by prepayment having a monetary value and makes a standard punch /
When it is determined that the printing is performed, that is, the SF card, the sorting unit 22 is controlled to transfer the ticket 2 to the SF processing unit 24.
Distribute to the side. The other tickets 2 are passed through the sorting unit 22 as they are, subjected to scissors punching, and then returned to the exit 4 or collected in the bill collecting box 40.

On the other hand, the ticket 2 distributed to the SF processing section 24 has its surfaces aligned in one direction by the reversing mechanism section 67 in accordance with the front and back sides thereof, and is directed to the standard punch 68 side in the next step by the belt 78. Be transported. A reference hole is opened according to the frequency of use of the boarding ticket 2 here, and other than that is passed through as it is.

When the ticket 2 passes the standard punch 68,
The ticket 2 is carried into the printing unit 69 by the belt 78.

When the SF card is carried in between the thermal head 89 and the platen roller 87, the platen roller 87 is pressed against the thermal head 87 by the platen roller 87, and the platen roller 87 is rotated. The ticket 2 is sent while being sandwiched between each other,
The surface in contact with the thermal head 89 (recording portion on the back surface)
For example, the boarding date, time, boarding station name, deduction balance, etc. are printed at a predetermined position. After that, the ticket 2 is SF
It is carried out from the processing unit 24 and finally discharged from the outlet 4.

Now, with reference to the timing chart of FIG. 5, the transport control operation of the ticket 2 in the vicinity of the printing unit 69 (printing section) of the SF processing section 24 will be described.

As shown in the figure, in this automatic ticket gate, the ticket 2 is normally conveyed at a high conveying speed of about 2000 mm / sec. However, in order to maintain the print quality of the ticket 2, the ticket is printed. In front of the unit 69, the transportation speed of the ticket 2 is reduced to a low transportation speed of about 30 mm / sec. When the ticket 2 is punched with the standard punch 68 as shown in the example in the figure, it is about 1000 mm / sec to 30 mm / se.
Decelerate to about c.

Actually, the ticket 2 transported on the transport path is detected by the sensor 84 arranged in front of the printing unit 69, the timing of deceleration is measured, and the transport speed is reduced. Just before the thermal head 89
The conveyance speed is about 30 mm / sec, and the platen roller 87 of the printing unit 69 is also rotationally controlled so as to have a feed speed that matches the speed, that is, 30 mm / sec. When the print position is reached, the ticket 2 is smoothly fed at 30 mm / sec, and printing is performed line by line on a dot-by-dot basis on the surface of the ticket 2. Character length) and width are printed.

By the way, the rubber roller 87a portion of the platen roller 87 expands and contracts due to changes in temperature and changes with time, so that the outer shape of the platen roller 87 as a whole changes.

Therefore, in this embodiment, when the operation inspection of the automatic ticket gate (in the test mode) is performed, the first ticket 2
To perform a test print.

In this case, after the character is printed on the ticket 2 by the printing unit 69, the contact line sensor 100 arranged behind it reads the character on the printed surface of the ticket 2 after printing, and the CPU 42 reads the character data. The height of the character is calculated based on the above, and the feed speed at which the ticket 2 is actually sent is calculated from the character height to determine what the roller diameter is.

After the determination, the CPU 42 obtains the correction value of the feed speed in order to obtain the normal feed speed, and the data of the next rotation speed of the platen roller 87 corresponding to the correction value is stored in the RAM4.
Remember in 6.

As a result, when the boarding ticket 2 is next conveyed to the printing unit 69 side, the CPU 42 makes the RAM.
The data stored in 46 is taken out, the motor speed control circuit 91 is controlled based on this data, and the platen roller 87 is rotated at an appropriate rotation speed to cause thermal head 89.
To print.

Now, the control operation will be described with reference to the flowchart of FIG.

First, after the ticket 2 conveyed into the SF processing section 24 passes through the standard punch 68, the printing unit 69
When it reaches the position of the pre-printing detector in front of and passes through this detector, its detection changes from dark to bright (step 601).
), The print position detection timer T11 starts counting time (step 602). Along with this, the transportation speed of the ticket 2 is switched to a low speed (step 603), and the belt 78 is decelerated from 2000 mm / sec to 30 mm / sec. As shown in Fig. 5, when the standard punching process is performed,
Decelerate from about 1000 mm / sec.

When the printing position detection timer T11 expires when the ticket 2 is conveyed to immediately before the printing unit 69 (step 604), the printing unit 69
The printing operation is turned on (step 605), and the printing operation on-time timer T12 starts counting time (step 606).

After printing, the print operation ON time timer T
When 12 has timed out (step 607), the printing operation of the printing unit 69 is turned off (step 608), and at the same time, the line sensor reading start timer T13 starts counting time (step 609).

Then, the line sensor reading start timer T13 is reached when the reading position of the contact line sensor 100 is reached.
When the time runs out (step 610), the contact line sensor 100 reads the characters on the ticket 2 (step 61).
1). After reading, the transportation speed of the ticket 2 is switched to a high speed (step 612), and the transportation speed of the belt 78 is 30 mm.
/ Sec to 2000mm / sec.

Along with this, the CPU 42 determines, based on the character data read this time, the roller diameter depending on the height (length per character) of the character printed on the ticket 2. To be judged.

That is, one character should be composed of, for example, 8 dots, but if it is, for example, 10 dots, it is determined that the height of the printed character is high, and if it is, for example, 7 dots, it is printed. It is judged that the height of the letters is low.

If the height of the printed characters is high, the roller diameter is large. Since the conveyance speed is too fast, the rotation speed should be corrected to be slow when printing next time, and vice versa. If the character height is low, the roller diameter is small, and the conveyance speed is low. Therefore, the correction is performed so that the conveyance speed at the next printing is increased.

In this way, the CPU 42 calculates the value of the deceleration speed at the time of the next printing, and the rotation speed of the platen roller 87 corresponding to the speed value is set (stored) in the RAM 46.

When the next ticket 2 is conveyed to the printing unit 69, the CPU 42 takes out the rotation speed which is the calculation result from the RAM 46 and controls the motor speed control circuit 91 so that it becomes the rotation speed. Accordingly, the motor rotation speed control circuit 91 rotates the platen roller 87 at the corrected rotation speed, and the thermal head 89 prints characters on the ticket 2.

Therefore, even if the outer dimensions of the platen roller 87 change, the printing height of the character is displaced at the first time, but from then on, the rotation speed is corrected based on the previous data each time. The speed at which the ticket 2 is sent while being in contact with the head surface of the thermal head 89 is constant, and printing quality can be obtained.

As described above, according to the present embodiment, in the SF processing section 24, the test print of the ticket 2 is executed in the test mode, the character of the ticket 2 is read by the contact line sensor 100 after the printing, and the CPU 42 Judges the external change of the platen roller 87 and corrects the rotation speed from the next time.

For example, if the print height is high, the roller diameter is large, and the rotation speed is corrected so as to be slow when printing next time. In this way, the rotation speed of the platen roller 87 is corrected to the optimum feed speed for the next ticket 2.

Therefore, even if the outer shape of the platen roller 87 changes, a constant print quality can be obtained.

Further, by disposing the contact line sensor 100 at the rear of the printing unit 69, it is possible to insert the ticket 2 in the maintenance program (test mode) and obtain an appropriate transport speed, and to print at the time of actual operation. Quality can be stabilized.

Further, even during the normal operation (operation) of the automatic ticket gate, it is possible to obtain an appropriate rotation speed of the roller for the next printing each time the SF card is conveyed.

[0067]

As described above, according to the first aspect of the invention, the feeding speed of the feeding means is controlled at the next printing on the basis of the print information of the recording medium printed by the printing means. That is, the feeding speed of the ticket can be made appropriate, and the printing quality of the ticket can be kept constant.

According to the second aspect of the invention, the feed speed when the recording medium is sent to the printing means is calculated based on the print information of the recording medium printed by the printing means, and the feed speed is used as the basis. Then, next time, the feeding speed of the feeding means when printing a new recording medium is corrected and the feeding means is controlled.
The feeding speed of the recording medium, that is, the ticket, can be made appropriate, and the printing quality of the ticket can be kept constant.

According to the third aspect of the present invention, the character reading means reads the characters on the recording medium printed by the printing means, and based on the data, the length in the feeding direction of the characters at the time of printing is calculated. Based on this, the feed speed at which the recording medium is sent is calculated, the feed speed of the feed means when printing a new recording medium is corrected next time, and the feed means is controlled so that the corrected feed speed is obtained. Further, the feeding speed of the recording medium, that is, the ticket, can be made appropriate, and the printing quality of the characters printed on the ticket can be kept constant.

According to the fourth aspect of the invention, even if the feeding speed of the feeding means changes due to temperature change, temporal change, etc., the information of the recording medium first printed by the printing means is read by the line sensor, and the information is read. Based on the above, the feeding speed at the time of the next printing is controlled, so that the feeding speed can be made appropriate and the printing quality on the recording medium, that is, the ticket can be kept constant.
