DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic ticket vending machine that automatically sells boarding tickets, coupon tickets, etc.

Generally, automatic ticket vending machines use a roll of paper, which is cut into appropriate lengths to create a ticket 'I'.
Published. In this case, the final edge of the paper cannot be issued as a ticket due to restrictions such as the positional relationship of the printing mechanism that prints on the paper and the cutting mechanism that cuts the paper and their respective sizes. , the remaining paper remains in the paper conveyance path. Therefore, before loading new paper into the automatic ticket vending machine, it is necessary to remove the remaining paper from the conveyance path.

Here, the operation for removing remaining paper from a conventional automatic ticket vending machine will be explained. Figure 1 (The conventional self [I!h
What is the configuration of the main parts of the ticket vending machine (hereinafter referred to as the ticket issuing unit)? In the figure, 1 is a sheet of paper wound in a four-circle shape. After the leading edge of the ITJ paper 1 is pulled out from the roll, it is stretched around a roller 2 and passed through paper guides 3a, 3.
b, is further held between conveyance rollers 4.5, passes through the cutting mechanism 6, and reaches between the thermal head 7 and the platen roller 8. The conveyance roller 4 and the platen roller 8 are each provided with a pulley 10.11 having a common axis, and the driving force of a motor (generally a stepping motor) 12 is transmitted to this pulley 10.11 via a belt 13. Then, [■Paper 1 is conveyed to the right side of the drawing. One end of a head spring 16 , which is a fulcrum of the shaft 151 , is in contact with the upper surface of the thermal head 7 , and the other end of the head spring 16 is locked to a locking pin 17 . This locking bottle 1
7 is provided on a plate-shaped frame 19 that is rotatable around a shaft 18, and the other end of the head spring 16 is engaged with the frame 19! When locked to the E bin 17, it rotates clockwise. Further, when the frame 19 rotates clockwise, the limit switch 20 is turned on, and it is possible to detect that the thermal head 7 is in pressure contact with the platen roller 8. In this case, if the limit switch 20 is not turned on, The motor 12 is not driven. On the other hand, the conveyance roller 5 is provided at one end of a V-shaped frame 22 that is rotatable around a shaft 21Tr.
The other end of the transport roller 2 is urged upward by a spring 23, so that the transport roller 5 is brought into pressure contact with the transport p-roller 4. A lever 24 is provided on the upper surface of the other end of the frame 22, and when the operator pushes this lever 24 downward, the pressure contact of the conveyance roller 5 is released. 25～
27 indicates whether the paper 1 is present or not at a predetermined position on the paper transport path. These are limit switches for detection, and are in the ON state when each paper 1 is detected. In this case, when the limit switch 25 is turned OFF, the device determines that the paper is too large and stops selling it, and the limit switches 25 to 27
Unless all of the limit switches 20 and 20 are turned on, the device will not be ready for sale. Reference numeral 30 denotes a main frame on which the above-mentioned components are placed, and can be pulled out by the operator in the direction of the arrow (towards the back of the apparatus) when loading paper.

In the conventional automatic ticket vending machine configured as described above, when the remaining amount of paper 1 becomes extremely small and the trailing edge of the paper 1 falls downward and leaves the detection point B of the limit switch 25, the device displays "no paper". As a result, the sale of the paper is discontinued, and the portion from the rear end of the paper 1 to the thermal head 7 is left in the conveyance path as residual paper. In this state, the operator pulls out the main frame 30 in the direction of the arrow, removes the head spring 16 from the locking pin 17 to release the thermal head 7 from pressure contact, and then pushes the lever 24 downward to cause the conveyance roller 5 to come into pressure contact. ? unlock. As a result, the paper conveyance path becomes open a', allowing the sweeper to pull out the remaining paper from the rear side of the apparatus. After removing the remaining paper, the lever 24 is returned to its original position, and the other end of the head spring 16 is locked to the locking bin 17. In this state, a new sheet of paper is loaded and the leading edge of this new sheet is inserted between the guide plates 5asab. As a result, the limit switch 25 is turned on and the limit switch 26 is also turned on, and this limit switch 26 is turned on.
When this happens, the motor 12 rotates and transports the leading edge of the paper to the position of the thermal head 7. Then, the leading edge of the paper is transported to the position of the thermal head 7, and the limit switch 27
By sending a predetermined size after turning ON, the device becomes ready for sale.

By the way, in the above-mentioned conventional automatic ticket vending machine, manual operation is required to open the paper conveyance path when removing residual paper, and furthermore, when setting new paper, the head spring 16 must be engaged. If you forget, the switch 20 will not turn on and the motor 12 will not turn on.
The problem is that the device is never ready for sale. That is, conventional automatic ticket vending machines have the disadvantage that they are troublesome to handle when loading paper and are prone to operational errors.

In view of the above-mentioned circumstances, the present invention provides an automatic ticket vending machine that is easy to handle when loading paper and is less likely to cause operational errors. a detection section that outputs a detection signal; a reverse conveyance section that conveys and discharges the paper in a direction opposite to that when issuing a ticket; and a reverse conveyance section that enables operation based on the detection signal of the detection section. a determination unit; and a discharge start command unit that causes the reverse transport unit to start operating when the reverse transport unit is in an operable state? It is characterized by the following:
