Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a ticket issuing device for an automatic ticket vending machine that sells train tickets, horse racing tickets, etc. by machine, and in particular, the present invention relates to a ticket issuing device for an automatic ticket vending machine that sells train tickets, horse racing tickets, etc. This invention relates to a ticket conveyance system that can send out tickets.

(2) Conventional technology and problems This type of conventional ticket issuing device drives a conveyance pulse motor by a predetermined number of conveyance pulses to convey a roll of paper, cuts a ticket from the leading edge of the roll, and sends it out. was. However, in this case, the number of conveyance pulses of the pulse motor is always constant, so if the rubber feed roller of the conveyance system that feeds out the roll paper deteriorates due to use, its outer circumference changes and the number of conveyance pulses is constant. The conveyance distance varied due to rotation. Therefore, the length of the ticket sent out was not constant and sometimes varied.

(3) Purpose of the Invention The present invention was made to solve the above-mentioned problems, and its purpose is to provide a ticket issuing device that can send out tickets of a certain length even if the ticket conveyance system deteriorates. do.

(4) Structure of the Invention According to the present invention, the above-mentioned object is to drive a conveyance pulse motor by a predetermined number of conveyance pulses to convey a roll paper, and to print a ticket of a certain length from the leading end of the roll paper. A ticket issuing device that cuts tickets with a cutter after being sent out, comprising a first detection section and a second detection section, which are provided at a certain distance upstream from the cutter in the middle of the conveyance path, and an initial detection section. a counter that counts the number of reference pulses required to pass between the first detection section and the second detection section during operation; and the above-mentioned transport pulses required to send out a ticket of a certain length based on the count by the counter. This is achieved by providing a ticket issuing device having a control section that calculates the number of tickets.

(5) Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an explanatory diagram showing a conveyance system of a ticket issuing device according to the present invention. This conveyance system consists of a roll paper 1, a pulse motor 2 for conveyance, and a rubber feed roller 3.
, a first detection section 4 , a second detection section 5 , and a cutter 6 . The roll paper 1 is sequentially fed out in the direction of arrow A from the leading end side by driving the pulse motor 2 by a predetermined number of transport pulses. Note that an appropriate guide 7 is provided on the path from the roll paper 1 to the feed roller 3. Further, reference numeral 8 is a pressing roller that presses the roll paper 1 against the feed roller 3.

The leading end of the roll paper 1 fed out as described above advances along the conveyance path as indicated by arrow B, and passes through the first detection section 4 provided along the way. The first detection section 4 detects passage of the leading end of the roll paper 1, and is composed of, for example, a photo sensor.
A second detection section 5 is provided at a certain distance _l1 from the first detection section 4. This second detection section 5 detects the passage of the leading end of the roll paper 1 after passing through the first detection section 4, and is composed of a photo sensor as described above.

The detection signals from the first detection section 4 and the second detection section 5 are input to the counter 9, as shown in FIG. This counter 9 starts counting in response to a detection signal from the first detection section 4 and stops counting in response to a detection signal from the second detection section 5. The number of reference pulses required for the roll paper 1 to pass a certain distance l ₁ to the second detection unit 5 is counted. Note that the above-described constant distance l ₁ has a specific relationship with the length l of a fixed-length ticket, which will be described later, such as l=nl ₁ , for example.

A cutter 6 is provided behind the second detection section 5. This cutter 6 cuts the leading end of the roll paper 1 sent out as described above to a certain length l, thereby sending out tickets such as train tickets, horse racing tickets, etc. of a certain length l. Note that in FIG. 1, reference numerals 11 and 12 are rubber rollers provided on the conveyance path of the roll paper 1.

Next, the operation of the ticket conveyance system according to the present invention will be explained. First, at the initial stage of operation, a ticket issue button (not shown) is pressed to drive the pulse motor 2, and the roll paper 1 is fed out along the conveyance path as indicated by arrows A and B by the feed roller 3. When the leading edge of the roll paper 1 reaches the position of the first detection section 4, the first detection section 4 detects the passage of the roll paper 1 and sends a detection signal _S1 to the counter 9. When this detection signal _S1 is input, the control section 10 sends the counter 9
A reset signal S3 is sent to the counter ₉ , and the count value of the counter 9 is reset to "0". At the same time, a count signal _S4 is sent from the control section 10 to the counter 9, whereby the counter 9 counts the number of pulses of the pulse motor 2 pulse by pulse. When the roll paper 1 is fed out by the drive of the pulse motor 2 and its leading end reaches the position of the second detection unit 5, the second detection unit 5 detects the passage of the roll paper 1 and sends a detection signal S. ₂ to counter 9. When this detection signal _S2 is input to the counter 9, the counter 9 stops counting, and the reference pulse required for the roll paper 1 to pass a certain distance _l1 from the first detection section 4 to the second detection section 5 is generated. This means that the number N ₁ has been counted. The reference pulse number N ₁ counted in this manner is sent to the control unit 10 as a reference pulse number signal S ₅ . The control unit 10 calculates the reference pulse number N ₁ from the above relational expression l=nl ₁ .
is multiplied by n to calculate how many pulses are required to send out a ticket of constant length l, and the number N ₂ of transport pulses required to issue an actual ticket is determined and stored in the storage area. In this way, the number N ₂ of transport pulses for sending out a ticket of a certain length l is determined, and when actually issuing a ticket next time, the number N ₂ of transport pulses is called from the storage area of the control unit 10 and the number of pulses is An instruction signal _S6 is sent to the pulse motor 2, and the pulse motor 2 is driven by a predetermined number of transport pulses _N2 . Then, a ticket of a certain length l is sent out from the end of the conveyance path.

When the power is turned off after being used for an appropriate period of time and the power is turned on again for use, at the initial stage of operation, the reference pulse number N ₁ is counted in the same manner as described above, and the new number of carrier pulses N ₂ is determined from this. Then, a ticket of a certain length l is sent out. Thereafter, in the same manner, after turning off the power, a new number of transport pulses _N2 is determined at the initial stage of operation to be used again. Therefore, even if the feed roller 3 deteriorates due to use and its outer circumference changes, the number of conveyance pulses will change accordingly.
N ₂ can be determined to send out tickets of constant length l.

(6) Effects of the Invention Since the present invention is configured as described above, even if the feed roller 3 of the conveyance system deteriorates due to use and its outer circumferential length changes, the first detection unit 4 detects the 2. Count the number of reference pulses required for the roll paper 1 to pass a certain distance l ₁ to the detection unit 5,
It is possible to calculate the number of transport pulses required to send out a ticket of a certain length. Therefore, the length of the ticket sent out can always be kept constant. Further, by changing the relationship between the reference pulse number and the transport pulse number, the length l of the ticket to be sent out can be changed as appropriate.
