Abstract

PURPOSE: To reduce the consumption quantity of an ink ribbon while reducing operation cost by unwinding the ink film by the length corresponding to one raw ticket after usual printing is applied to the raw ticket and applying reversal printing to journal paper. CONSTITUTION: At a time of note issuing, at first, a raw ticket is sent out of a hopper 1 to be fed to the gap between a thermal head 7 and a platen by a feed roller 3. At this time, the thermal head 7 is allowed to fall through a cam 6 by the rotation of a motor 20 to bring the raw ticket 2 into close contact with an ink film 25. Next, the rotation of the platen 8 is started by rotating motors 9, 20 and, at the same time, printing is applied to the raw ticket by the thermal head 7 while the ink film 25 is taken up. When the discharge of the raw ticket (customer delivery ticket) 2 is completed, journal paper is sent out of the hopper 21 and the so-called reversal printing wherein the characters printed on the raw ticket 2 by the previous operation are extracted white is performed to discharge the journal paper after printing.

2. Description of the Related Art Ticket issuing printers used to issue various tickets such as boarding tickets, airline tickets, and reservation tickets are handled by a thermal transfer printing mechanism which is difficult to forge because the issued tickets are handled as cash vouchers. It is configured to print.
In such a conventional ticket issuing printer, after printing a ticket to be passed to a customer (passing ticket), the issued content is recorded as a record. Therefore, the same content is printed again on the journal paper by the thermal transfer printing mechanism unit. Alternatively, another printing mechanism is provided so that the same content is printed on the journal paper.

[0003]

In the case of the conventional ticket issuing printer as described above, in the former case, since one ticket is printed on the ticket and the journal paper by one printing mechanism, the consumption amount of the ink ribbon is reduced. It has many drawbacks, that is, operating costs are high, and the number of times the ink ribbon is replaced is large, which is troublesome.

Further, in the latter case, since two printing mechanism parts, a printing mechanism part for issuing a ticket and a printing mechanism part for journal printing, are required, the structure becomes complicated and the manufacturing cost becomes high, and the issuing ticket is issued. There is a problem in that the size of the entire printer becomes large.

[0005]

In the ticket issuing printer of the present invention, a first hopper for loading original sheets cut into a predetermined length and sending the sheets one by one, and a journal cut into the same length as the original sheets. A second hopper for stacking sheets and feeding them one by one, an ink film provided with an equal interval transparent portion outside the print area, which is a little longer than the length of the original ticket, and the transparent portion of the ink film is detected. An ink film sensor, a motor that drives the ink film in both forward and reverse directions, a thermal head that alternately prints on the original ticket and the journal sheet via the ink film, and a thermal head that is provided to face the thermal head. The platen and the original ticket or the journal are lowered by lowering the thermal head when printing on the original ticket or the journal paper. A thermal head elevating mechanism that presses the paper against the platen via the ink film is provided, and after printing the original ticket through the ink film by the thermal head to issue a ticket, before the portion used for the printing When the ink film is rewound by the motor until the transparent part of the part is detected by the ink film sensor, and then printing is performed on the journal paper, the voltage is applied to the entire heating element of the thermal head and the previously printed characters are printed. In this case, reverse printing is performed in a state of white.

In FIG. 1, a hopper 1 stacks original sheets cut into a predetermined length and sends them out one by one. Hopper 21
Is a stack of journal paper cut to the same length as the original ticket and sent out sheet by sheet. The transport roller 3 transports the original ticket from the hopper 1 or the journal paper from the hopper 21 toward the thermal head 7. The sensor 4 detects the original ticket or the journal sheet conveyed by the conveying roller 3. The head holding roller 5 is provided on the thermal head 7, and cooperates with the cam 6 to participate in the vertical movement of the thermal head 7. The platen 8 is provided below the thermal head 7, and is placed between the platen 8 and the thermal head 7 during the printing operation (see FIG. 2) or the journal paper 2.
2 (see FIG. 7). The motor 9 drives the ink film 25 in both forward and reverse directions. Pulleys 10 and 1
1 is attached to each of the two shafts that respectively hold the ink film 25, and has a built-in one-way clutch. Motor 9 shaft and pulleys 10 and 11
A belt 26 is wound around and the rotation of the motor 9 is transmitted to the shaft holding the ink film 25. Torque limiters 12 and 13 are provided between the pulleys 10 and 11 and the shaft to which they are respectively attached. The head position sensor 14 is provided so as to face the side surface of the thermal head 7, and the sensing plate 15 provided on the side surface of the thermal head 7.
To detect. The ink film sensor 16 has a transparent portion 29 provided on the edge of the ink film 25 (see FIG. 6).
To detect. The sensor 17 detects the original ticket printed by the thermal head 7, that is, the customer ticket or the journal paper. The transport path 18 is a path for passing the original ticket from the hopper 1 to the discharge stacker 19 via the thermal head 7. The motor 20 includes a pulley 23 and a pulley 2 having a one-way clutch built in by a belt 27.
4, the pulley 23 rotates the platen 8 in a predetermined direction to cause a line feed operation of the original ticket or the journal sheet, and the pulley 24 rotates the cam 6 in a predetermined direction to rotate the thermal head 7 Drive the lifting movement of.

Next, the operation of the embodiment configured as described above will be described with reference to FIGS.

When a ticket is to be issued, first, the original ticket is sent out from the hopper 1, and the original ticket 2 is conveyed to the thermal head 7 and the platen 8 by the conveying roller 3, as shown in FIG. At this time, when the sensor 4 detects the original ticket 2, the signal causes the motor 20 to start rotating in the direction of arrow A, and the pulley 24 is rotated via the belt 27. As a result, the cam 6 rotates and the head holding roller 5
The thermal head 7 descends and comes into close contact with the platen 8 via the original ticket 2 and the ink film 25. At this time, the pulley 23 also rotates, but the pulley 2
Since the lock direction of the one-way clutch of No. 3 is opposite to the lock direction of the one-way clutch of the pulley 24, the platen 8 does not rotate.

Subsequently, the motor 9 is rotated in the direction of arrow B,
When the motor 20 is rotated in the direction of arrow C opposite to the direction of arrow A, the platen 8 starts to rotate, and at the same time, the ink film 25 is also wound around the shaft on which the pulley 10 is mounted. At this time, since the torque limiters 12 and 13 are provided on the shafts on which the pulleys 10 and 11 are mounted, respectively, even if the winding diameter of the ink film 25 of each shaft changes, the ink film at the position of the platen 8 is also changed. The traveling speed of 25 is the same as the peripheral speed of the platen 8. Further, the one-way clutch of the pulley 10 transmits the rotation of the motor 9 to its shaft, but the one-way clutch of the pulley 11 has a locking direction opposite to the locking direction of the one-way clutch of the pulley 10, so that the rotation of the motor 9 is rotated. Is not transmitted to that axis.

When the original ticket 2 reaches between the thermal head 7 and the platen 8, as shown in FIG. 3, a voltage is supplied to a portion of the heating element array of the thermal head 7 which is necessary for printing characters. Print.

Subsequently, as shown in FIG. 4, when the rear end of the printed original ticket (passenger ticket) 2 is detected by the sensor 17, the operation of the motor 9 and the motor 20 is stopped, and the motor is further stopped. 20 is rotated in the direction of arrow A. As a result, the cam 6 also rotates, so that the head holding roller 5 is pushed up by the cam 6, so that the thermal head 7 rises and separates from the platen 8. The sensing plate 15 also rises due to the upward movement of the thermal head 7, and the head position sensor 14 causes the sensing plate 1 to move.
5 is detected. When the head position sensor 14 detects the sensing plate 15, the operation of the motor 20 is stopped. The original ticket (passenger ticket) 2 is subsequently conveyed by the conveying path 18 and discharged to the discharge stacker 19 (see FIG. 1).

As shown in FIG. 5, the ink film 25 is provided with transparent portions 29 at equal intervals on the outer edge of the printing area 28 which is an area used for printing. The interval P between the transparent portions 29 is set to be slightly larger than the length D of the original ticket 2 (and the Jojour paper). The transparent portion 29 is detected by the ink film sensor 16.

When the discharge of the original ticket (passing ticket) 2 is completed,
As shown in FIG. 6, the motor 9 is rotated in the arrow E direction opposite to the arrow B direction. As a result, the ink film 25 is directed toward the shaft on which the pulley 11 is attached (arrow F
Direction), and stops when the ink film sensor 16 detects the previous transparent portion 29.

Next, the journal paper is sent out from the hopper 21. The journal paper is transported to the thermal head 7 and the platen 8 by the transport roller 3 similarly to the original ticket, and when the sensor 4 detects the journal paper, the motor 20 starts rotating in the direction of arrow A and passes through the belt 27. To rotate the pulley 24. As a result, the cam 6 rotates and separates from the head holding roller 5, so that the thermal head 7 descends and comes into close contact with the platen 8 via the journal paper and the ink film 25. Further, the motor 9 is rotated in the arrow B direction, the motor 20 is rotated in the arrow C direction, and the platen 8 and the ink film 25 are driven.

When the printing position of the journal paper reaches between the thermal head 7 and the platen 8, as shown in FIG. 7, voltage is supplied to the entire heating element array of the thermal head 7 to perform printing. As a result, so-called reverse printing is performed on the journal paper 22 in which the characters printed on the original ticket (passenger ticket) 2 by the previous operation are blank.

Then, similarly to the case of the original ticket (passenger ticket) 2, when the sensor 17 detects the trailing edge of the printed journal sheet 22, the motor 9 and the motor 20 are driven.
Is stopped, and the motor 20 is further rotated in the direction of arrow A. As a result, the head position sensor 14
The thermal head 7 ascends and separates from the platen 8 until the sensing plate 15 is detected. The printed journal paper 22 is ejected to a reject stacker (not shown).

[0019]

As described above, in the ticket issuing printer of the present invention, one thermal head is used to carry out normal printing on an original ticket, and then a length corresponding to one original ticket. Only by rewinding the ink film and performing reverse printing by supplying a voltage to the entire heating element array of the thermal head 7 for the journal paper, the same content as that printed on the original ticket is printed on the journal paper. Since it is possible to perform reverse printing, it is possible to print both the original ticket and the journal paper with an ink film having a simple structure and having a length corresponding to one original ticket. There is an effect. Therefore, there is an effect that the consumption amount of the ink ribbon can be reduced and the operating cost can be reduced, and the number of times of exchanging the ink ribbon can be reduced to save the labor for the exchange work.
