[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ticket issuing machine suitable for use in a ticket vending machine, etc., and in particular, paper feeding in a printing section and a conveying section (discharging means) is carried out by the same motor. The present invention relates to a ticket issuing machine which is designed to reduce the size and cost of the entire device by doing so.

[Conventional technology]

FIG. 4 is a side view showing the configuration of a conventional ticket issuing machine. In this figure, 1 is a sheet of paper wound into a roll. The paper 1 is guided to a platen roll 6 via a guide roll 2, a paper out detection switch 3, a feed roll 4, and a cutter 5. A timing belt 8 driven by a stepping motor 7 is stretched between the feed roll 4 and the platen roll 6, and pulls the paper 1 toward the cutter 5, and the cutter 5 cuts the paper to the length of the ticket. The paper (ticket) 1a cut into
It is conveyed between a thermal head 9 provided opposite to this. Note that the cutter 5 and the thermal head 9 constitute a printing section 10.

The ticket 1a printed by the thermal head 9 is discharged to the outside by a conveying section 11.
The conveyance unit 11 includes a pair of exit rolls 12 and 13,
A conveyance belt 14 stretched between the exit rolls 12 and 13, a conveyance motor 15 that drives the conveyance belt 14, and a photoelectric element 1 that detects passage of the ticket 1a.
6, and the ticket 1a is discharged from the ticket exit 17 to the outside.

In such a configuration, when a ticket issue command is issued, the stepping motor 7 and the conveyance motor 15 start rotating as shown in FIG. 5 (step S1 in FIG. 6), and paper feeding and printing are performed ( step
S2, S3). That is, when the stepping motor 7 rotates, the feed roll 4 and platen roll 6 rotate via the timing belt 8 to feed the paper 1 and the ticket 1a little by little, and the thermal head 9 prints on the ticket 1a. (Step S3). Note that this ticket 1a had been conveyed between the platen roll 6 and the thermal head 9 and was in a waiting state at the end of the previous ticket issue, and had already been cut into a predetermined length by the cutter 5. .

When printing by the thermal head 9 is completed, the leading edge of the ticket 1a reaches the exit roll 12, and the stepping motor 7 is stopped (step S4 and FIG. 5). Then, the paper 1 is cut by the cutter 5 to produce the next printed ticket 1a (step S5), while the previously printed ticket 1a is cut by the conveyor belt 14 driven by the conveyor motor 15. was transported (step S6),
The ticket is discharged from the ticket exit 17 to the outside. in this case,
After the passage of the ticket 1a is confirmed by the photoelectric element 16, the conveyance motor 15 is stopped (step
S7, S8 and Figure 5).

[Problem to be solved by the invention]

By the way, in the conventional ticket issuing machine mentioned above,
A stepping motor 7 is provided to feed the paper 1 wound into a roll to the printing section 10, and to send out the paper (ticket) 1a cut and printed by the printing section 10, and also to send it out from the printing section 10. Since a separate transport motor 15 was provided to eject the paper 1a to the outside, two motors, the stepping motor 7 and the transport motor 15, were required, which made the entire ticket issuing machine more compact and inexpensive. This was a hindering factor.

This invention was made in view of the above-mentioned circumstances, and uses a single motor as a drive source to feed paper into a printing unit and discharge paper (tickets) that have been cut and printed in this printing unit to the outside. By doing so, we aim to reduce the number of parts and downsize the machine, and furthermore, by using a single motor, we reduce the drive circuit, thereby reducing the cost of the entire device. purpose.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention includes a printing section having a printing head and a cutter, and a paper wound in a roll is sent to the printing section, and the printing section cuts the paper and sends out the printed paper. In a ticket issuing machine having a paper feed means and a discharge means for discharging the paper sent out from the printing section to the outside, a single motor rotates in the forward direction when driving the paper feed means and rotates in the reverse direction when driving the discharge means. a first transmission means that transmits the rotation of the motor to the paper feeding means only when the motor rotates in the normal direction; and a first transmission means that reverses the rotation of the motor and transmits it to the ejecting means only when the motor rotates in the reverse direction. It is characterized by comprising two transmission means.

[Effect]

According to the above configuration, when the motor rotates in the normal direction, the rotation of the motor is transmitted to the paper feeding means via the first transmission means, whereby the paper is sent to the printing section and printed. When the motor rotates in reverse, the rotation of the motor is transmitted to the ejection means via the second transmission means, thereby ejecting the printed paper. Therefore, the paper feeding means and the ejection means can be driven by a single motor.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing the configuration of a ticket issuing machine according to an embodiment of the present invention. This embodiment differs from the conventional ticket issuing machine shown in FIG. 4 in the following points.

(1) There is no transport motor 15 and a drive circuit (not shown) for electrically driving it.

(2) There is no exit roll 13. Also, the exit roll 12
is adapted to be rotationally driven by a belt 21 driven by a stepping motor 7.

In this case, the output shaft 7 of the stepping motor 7
As shown in FIG. 2, a one-way clutch 22 is inserted between the timing belt 8 and the timing belt 8, so that the timing belt 8 is driven only when the stepping motor 7 rotates in the normal direction. Also, a belt 21 that transmits the driving force of the stepping motor 7 to the exit roll 12, and a belt 21 that transmits the driving force of the stepping motor 7 to the exit roll 12,
A one-way clutch 23 is also interposed between the two shafts, so that the exit roll 12 is rotationally driven only when the stepping motor 7 is in reverse rotation. Note that the belt 21 is stretched in a cross-legged manner.

(3) A one-way clutch is also attached to the presser roll 25 (FIG. 1) located opposite the feed roll 4 to prevent the waiting tickets 1a from flowing backward while the stepping motor 7 is rotating in reverse. I have to.

Here, to explain the correspondence between each component of the above-mentioned embodiment and each element of the means for solving the problem, the cutter 5 and the thermal head 9 constitute the printing section 10, and the feed roll 4 and the platen. The roll 6 constitutes a paper feeding means, the timing belt 8 and one-way clutch 22 constitute a first transmission means, the belt 21 and one-way clutch 23 constitute a second transmission means, and the exit roll 12 constitutes a discharge means. Correspondingly, the stepping motor 7 corresponds to a single motor, and the thermal head 9 corresponds to a printing head.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

Steps SP1 to SP5 in FIG. 3 correspond to steps S1 to S5 in FIG. 6, so their explanation will be omitted. At step SP6, when the stepping motor 7 is rotated in the opposite direction to that during printing, the output roll 12 is rotated and the printed ticket 1a is conveyed to the outside (step SP7). And photoelectric element 16
When the passage of the ticket 1a is confirmed (step SP8), the stepping motor 7 is stopped (step SP9), and the ticket issuing operation is completed.

In this way, since the stepping motor 7 is used to feed the paper during and after printing, only one motor is required, and the apparatus can be made smaller and less expensive.

Furthermore, in the conventional ticket issuing machine, an AC motor is used as the conveyance motor 15 in consideration of cost reduction and maintainability. Therefore, two power sources were required: a power source for the transport motor 15 (AC100V) and a DC power source for the stepping motor 7 (DC24V), but according to this embodiment, the DC power source for the stepping motor 7 is You can get the advantage of only needing

〔Effect of the invention〕

As explained above, in the present invention, since the paper feeding means and the ejection means are configured to be driven by a single motor, the following effects can be obtained.

Unlike conventional devices in which the paper feeding means and ejecting means are driven by separate motors, the present invention uses a single motor to drive the paper feeding means and ejection means, so the overall structure of the device can be downsized.

Since there is only one motor, naturally only one motor drive circuit is required.

Although the number of transmission means is increased compared to the conventional method, since this is inexpensive, the effect of lowering the price by reducing the number of motors by one is greater, and the cost becomes lower than the conventional method.
