Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ticket issuing apparatus that prints data and magnetically records data on a ticket such as a ticket, and more particularly to a device that can record magnetic data at a correct pitch.
[0002]
[Prior art]
In recent years, automated ticket gates have been advanced on railways, and data on printed and magnetic data is recorded on tickets and express tickets in order to enable automatic ticket checking.
Even if a ticket or limited express ticket is issued to a passenger whose conductor has overtaken a train or other vehicle, unless the data is printed and magnetically recorded on the ticket, the passenger may pass through the automatic ticket gate when getting off. Can not. For this reason, development of a portable ticket issuing device capable of printing and magnetic recording has been conventionally promoted.
[0003]
The group of the inventors of the present invention has previously proposed a ticket issuing device capable of issuing a large refill ticket of 85 mm.
As shown in FIG. 14, this apparatus has a size that can be held by one hand, a ticket storage cassette 10 for stacking and storing large 85 mm tickets, and magnetic data on a ticket pulled out from the ticket storage cassette 10. , A printing unit 12 having a print head for printing on a note paper and a print feed roller for feeding a note being printed, a stepping motor 13 as a drive source, a DC A motor 14 and a transmission mechanism such as a gear for transmitting the driving force of the driving source to each unit are provided.
As shown in FIG. 15, the magnetic recording section 11 includes a magnetic head 21 for recording magnetic data and a magnetic recording feed roller 22 for conveying a note (see Patent Document 1 below).
[0004]
The magnetic recording feed roller 22 and the print feed roller of the printing unit 12 need to precisely control the rotation angle in order to accurately set the position of magnetic recording and printing. The stepping motor 13 that rotates at a constant angle by an excitation pulse is used as a drive source of the print feed roller 22 and the print feed roller. On the other hand, the DC motor 14 is used as a drive source of a mechanism that does not require much precision and that feeds out the bills from the bill storage cassette 10 and switches the passage of the bills.
[0005]
The printing unit 12 prints items such as a ticket type, a fare, and a date of issuance on the surface of the ticket while conveying the ticket with the printing feed roller. Since the printing unit 12 must write the printing data for each line at a constant pitch, the printing data is written for each line in synchronization with the excitation pulse of the stepping motor 13. Further, in order to improve the printing quality, when the number of printing dots per line is large, the stepping motor 13 is controlled so as to reduce the transport speed of the bill, and the rotation amount of the printing feed roller is adjusted. I have.
[0006]
Similarly, when magnetic data is written on a note, each bit of the magnetic data must be written at a predetermined fixed pitch. Therefore, the stepping motor is rotated while rotating the magnetic recording feed roller 22 to convey the note. The magnetic data is written in synchronization with the excitation pulse to the T.13.
[0007]

[Problems to be solved by the invention]
However, in this conventional ticket issuing apparatus, when each bit of magnetic data is written on a ticket in synchronization with the excitation pulse timing of the stepping motor, the rotation angle error of the stepping motor and the driving force of the stepping motor are magnetically recorded. Due to the rotation angle error of the transmission mechanism that transmits to the paper feed roller, the writing pitch of magnetic data on the paper sheet becomes uneven, and as a result, when this paper sheet is passed through an automatic ticket gate, it is rarely read. The problem that an error occurred was found.
[0009]
Even if the printing position is slightly shifted, the human eyes can identify the printed content, but an automatic ticket gate that reads the magnetic data mechanically will identify the data content if the magnetic data writing pitch is not accurate. I can't.
To reduce the rotation angle error, the accuracy of the transport system including the motor must be improved, and the cost increases.
[0010]
In addition, when a motor other than the stepping motor is used, it is difficult to control the transport speed to change the transport speed according to the number of print dots per line during printing. However, providing a stepping motor for printing and another motor for magnetic recording leads to an increase in the size and cost of the apparatus.
[0011]
An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a ticket issuing device capable of improving the accuracy of a magnetic writing pitch while using a stepping motor.
[0012]
[Means for Solving the Problems]
Therefore, in the present invention, a ticket issuing device includes a magnetic recording unit that performs magnetic recording on a ticket, a magnetic recording transport roller that transports the ticket on which magnetic recording is performed by the magnetic recording unit, and a ticket. A printing means for printing on the paper, a printing transport roller for transporting a note on which printing is performed by the printing means, a stepping motor for driving both the magnetic recording transport roller and the printing transport roller, and a magnetic recording apparatus. Rotation amount detection means for detecting the rotation amount of the conveying roller for printing, the printing means sets the timing of printing on the note based on the excitation pulse of the stepping motor, and the magnetic recording means, the rotation amount detection means The timing of magnetic recording on a note is set based on the detected rotation amount of the magnetic recording transport roller.
[0013]
In this ticket issuing device, the rotation amount of the magnetic recording transport roller is detected, and the magnetic data is written on the bill in synchronization with the rotation amount, so that a uniform writing pitch can be obtained. Further, in this apparatus, it is not necessary to use a motor having a high rotation angle accuracy, and it is not necessary to share the paper transport for magnetic writing and printing with separate motors, so that the apparatus can be downsized and the cost can be reduced. It can be kept low.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
As shown in a perspective view of FIG. 1, a ticket issuing device according to an embodiment of the present invention includes a rotating disk 31 having a large number of holes on a circumference and supported by a rotating shaft of a magnetic recording feed roller 22; And an optical sensor 32 that detects a hole in the rotating disk 31 and outputs a pulse waveform signal, which is fixed to the frame body. The encoder 30 rotates the feed roller 22 for magnetic recording. Detect the amount. The perspective view of FIG. 2 shows the device of FIG. 1 as viewed from the back (the same side as FIG. 14). The magnetic recording feed roller 22 is driven by a stepping motor 13 as in the conventional apparatus (FIG. 14), but the rotation amount of the magnetic recording feed roller 22 is detected by the encoder 30 and output from the encoder 30. The magnetic head performs magnetic writing on the ticket in synchronization with the rotation timing of the magnetic recording feed roller 22. Other configurations are the same as the conventional device.
[0015]
This device includes a DC motor as a driving source, as in the conventional device (FIG. 14), but is not shown in FIG.
FIG. 3 is a cross-sectional view taken along a dashed line in FIG. Large-diameter 85 mm tickets are stacked and stored in the paper note storage cassette 10. The magnetic recording feed roller 22 is disposed so as to be in contact with the magnetic head 21. The printing unit 12 includes a print feed roller 41 driven by the stepping motor 13 and a print head 42 that prints on a note paper. Further, the passage toward the printing unit 12 is opened when the conveyance direction switch 43 for switching the conveyance direction rotates clockwise in FIG. 3 around the support shaft. The transport direction switch 43 is driven by a DC motor.
[0016]
4 shows the positional relationship between the magnetic recording unit 11, the stepping motor 13 and the printing unit 12, and FIG. 5 shows the magnetic recording feed roller 22 of the magnetic recording unit 11 and the printing unit 12 from the stepping motor 13. The transmission mechanism of the driving force to the printing feed roller 41 is shown.
[0017]
Next, the operation of this device will be described. FIG. 6 shows an operation sequence of this device.
When the DC motor rotates forward (A in FIG. 6), the bills stored in the bill cassette 10 are fed out of the bill cassette 10 by a feeding claw (not shown) as shown in FIG. When the leading end of the paper sheet approaches the magnetic recording feed roller 22, the stepping motor starts normal rotation (B in FIG. 6), and accordingly, the magnetic recording feed roller 22 starts normal rotation. The bill is held between the magnetic recording feed roller 22 and the magnetic head 21 and is completely pulled out from the bill cassette 10 and transported as shown in FIG. When the paper sheet moves to the standby position where it is disengaged from the magnetic recording feed roller 22, the stepping motor stops normal rotation and starts reverse rotation (FIG. 6E), and accordingly, the magnetic recording feed roller 22 starts reverse rotation. The paper note is pushed back to the magnetic recording feed roller 22 side by the paper sheet return mechanism 51, and is conveyed in the reverse direction by the magnetic recording feed roller 22 that rotates in the reverse direction, as shown in FIG. At this time, the magnetic head 21 writes the magnetic data on the ticket transported in the reverse direction (FIG. 6E).
[0018]
The write timing of each bit of the magnetic data is not synchronized with the excitation pulse of the stepping motor, but is synchronized with the number of pulses output from the rotating encoder 30. Therefore, regardless of the rotation angle accuracy of the stepping motor, the timing of reversing the magnetic data is set according to the rotation angle of the magnetic recording feed roller 22 (that is, according to the transport distance of the paper sheet). Magnetic data can be written on paper at a uniform pitch.
[0019]
As shown in FIG. 10, when the note on which the magnetic data is written is conveyed in the reverse direction and moves to the standby position where it is separated from the magnetic recording feed roller 22, the writing of the magnetic data is stopped, and the stepping motor rotates in the reverse direction. Is stopped, and the reverse rotation of the magnetic recording feed roller 22 ends (FIG. 6F). In addition, the DC motor activates the transport direction switch 43 to open a passage for guiding the bill to the printing unit 12 (FIG. 6F).
The paper note return mechanism 51 pushes the paper sheet back to the magnetic recording feed roller 22, and when the leading end of the paper sheet approaches the magnetic recording feed roller 22, the stepping motor resumes normal rotation (G in FIG. 6). Accordingly, the magnetic recording feed roller 22 starts to rotate forward, and conveys the bill in the forward direction as shown in FIG. At this time, the magnetic head 21 reads the magnetic data recorded on the ticket, and checks whether the magnetic data has been correctly recorded (FIG. 6G).
[0020]
If the magnetic data recorded on the bill is correct, the bill is guided by the transport direction switch 43 and transported in the direction of the printing unit 12, as shown in FIG. When the leading end of the note paper approaches the printing unit 12, the DC motor starts and moves the print head 42 to the printing position (FIG. 6I). The stepping motor rotates forward to rotate the print feed roller 41 (FIG. 6J), and the note is discharged while being printed. When the printing of the bill is completed, the DC motor returns the feeding claw to the original position, and returns the transport direction switch 43 and the print head 42 to their original positions (FIG. 6K).
As described above, in the ticket issuing device of this embodiment, the rotation of the magnetic recording feed roller 22 for feeding the ticket is detected by the encoder, and the magnetic writing is performed in accordance with the rotation. The write pitch of the magnetic data can be made uniform without being affected.
[0021]
FIG. 13 schematically shows the difference between the case where the timing of writing magnetic data on the ticket is adjusted to the excitation pulse of the stepping motor and the case where the timing is adjusted to the pulse of the encoder attached to the magnetic recording feed roller 22. ing. As shown in FIG. 13A, when the magnetic data writing timing is managed by the excitation pulse of the stepping motor, the rotation angle error of the stepping motor and the driving force of the stepping motor are transmitted to the magnetic recording feed roller. Due to the rotation angle error of the transmission mechanism, the rotation angle of the magnetic recording feed roller 22 per one pulse varies, so that the lengths of the magnetic data written on the bills become uneven.
[0022]
On the other hand, in the case of the pulse of the encoder attached to the magnetic recording feed roller 22, the rotation angle of the magnetic recording feed roller 22 per pulse is constant even when the rotation speed of the magnetic recording feed roller 22 changes. Therefore, the moving amount of the bill per pulse is constant, and the magnetic data can be written at a uniform pitch in accordance with the movement of the bill. Therefore, the magnetic recording accuracy can be improved.
Here, an optical encoder is illustrated as an encoder, but another encoder such as a magnetic encoder may be used.
[0023]
【The invention's effect】
As is clear from the above description, the ticket issuing apparatus of the present invention can make the write pitch of magnetic data uniform without being affected by the rotation angle error and the speed fluctuation of the stepping motor, thereby improving the recording accuracy. Can be achieved.
In addition, the conveyance in magnetic recording and printing can be performed by one motor instead of separate motors, and the device can be reduced in size and weight, and the cost can be reduced. Can be provided.
