Referring to Figures 3 to 8 the operation of the receipt machine according to the present invention configured as described above is as follows.

First, the receipt issuing machine 20 is electrically connected to the billing computerized management system or the point-of-sale management system through the connection port and the cable, respectively, and then the power of the management system and the receipt machine 20 is turned on. Then, the receipt issuing machine 20 is in a ready state capable of issuing a receipt under the control of the management system.

Here, when the receipt machine 20 is connected to the toll gate computer management system of the highway toll gate, the receipt machine is operated by the driver and when the receipt machine 20 is connected to the point of sale management system such as a discount store, the customer or a clerk operates. It can be understood that.

As a result, the toll collector receives the toll, or the clerk has received the payment for the goods and has finished entering data into the management system, so that the object (e.g., toward the proximity sensor 29 of the receipt issuer 20). For example, when a driver or a customer's hand approaches, the control unit of the management system (not shown) receives a receipt issuance signal from the proximity sensor 29.

Then, the control unit of the management system as shown in Figure 8, the thermal paper sheet 23a from the thermal paper roll 23 of the thermal paper roll storage unit 24 by the feeding unit 26 of the printer unit 27 ), A predetermined printing is performed on one surface of the thermal paper 23a through the thermal printer head 25 of the printer unit 27 (S800).

Subsequently, the feeding unit 26 of the printer unit 27 cuts the printed thermal paper 23a according to the printing speed of the thermal paper 23a through the thermal printer head 25. Transferring to the entrance port 41b of the feeding presenter 40 through the space (S802).

Subsequently, the feeding roller unit 50 which is driven by the driving motor 44 of the feeding presenter 40 is printed when the printed thermal paper 23a reaches the entrance opening 41b of the feeding presenter 40. The thermal paper 23a is transferred to the discharge port 41c of the feeding presenter 40 (S804).

Subsequently, the cut portion 28 prints the thermal print before the printed thermal paper 23a protrudes out of the outlet 21b of the receipt machine 20 such that the printed thermal paper 23a can be pulled by a driver or a customer. The rear end of the sheet 23a is cut (S806).

Meanwhile, in S804, when the printed thermal paper 23a approaches the entrance 41b of the feeding presenter 40, the feeding start detecting sensor 46 detects the entry of the thermal paper 23a to manage the corresponding paper. A thermal paper entry signal is generated to the controller of the system, and the controller of the management system that senses the signal applies a current to the driving motor 44 in the feeding presenter 40.

Accordingly, the output side of the drive motor 44 is rotated so that the input side pulley 60 of the feeding roller unit 50 connected to the output side pulley 60a is driven via the driving belt 61, As a result, the feeding roller 52 of the first roller shaft 51 of the feeding roller unit 50 rotates to transfer the printed thermal paper 23a from the inlet 41b toward the outlet 41c.

At this time, the idle roller 55 of the second roller shaft 54 facing the first roller shaft 51 is rotated together with the feeding roller 52 through the printed thermal paper (23a). The idle roller 55 is elastically supported by the leaf spring 56 via the second roller shaft 54 to give an adhesive force between the idle roller 55 and the feeding roller 52 to print the printed roller. It is easy to discharge the thermal paper (23a).

Subsequently, when the thermal paper 23a is transferred to the discharge port 41c, the feeding completion sensor 47 in the feeding presenter 40 detects the arrival of the thermal paper 23a to generate a thermal paper arrival signal. The control unit of the management system that senses the signal cuts off the current applied to the drive motor 44 after a predetermined time so that the front end portion of the printed thermal paper 23a is sufficiently discharged to the outside.

At this time, the printed thermal paper 23a passing through the discharge port 41c of the feeding presenter 40 may be discharged larger than the length that can be pulled by the hand of the driver or the customer. In addition, the protruding length of the printed thermal paper 23a protruding out of the outlet 21b of the receipt issuing machine 20 is determined by the rotation speed of the drive motor 44.

Thus, a substantial portion of the printed thermal paper 23a is exposed out of the outlet 41c of the feeding presenter 40, and the remaining rear portion of the leaf spring 56 supporting the second roller shaft 54. The elastic force is fixed between the feeding roller 52 and the idle roller 55 of the feeding roller unit 50 in the feeding presenter 40 with a predetermined holding force.

As described above, a portion of the printed thermal paper 23a is discharged out of the outlet 21b of the receipt machine 20, using a checkout counter such as a driver of a vehicle passing through a toll gate of a paid road, or a discount store. The customer can pull out the printed thermal paper 23a from the outlet 21b of the receipt issuer 20 by himself or herself according to the need of the receipt.

As described above, the present invention allows a person who needs a receipt (or thermal paper) to receive a receipt by themselves.

In addition, the present invention allows a person who needs a receipt to receive a receipt more conveniently through the proximity sensor.

In addition, the present invention allows the thermal paper is smoothly discharged to the outer outlet side of the case from the thermal paper roll of the thermal paper roll receiving portion.

Furthermore, the present invention allows the rear end of the thermal paper to be neatly cut before reaching the state where the thermal paper can be pulled out from the outlet of the receipt machine by the hand of the driver or the customer (or the clerk).
