As shown in FIG. 5B, the user peels off the seal 5A including the print portion 5 formed of a facial image from the print 1A along the half-cut line 7, and the seal 5A is attached to the object ( It is used by adhering on (not shown).

Next, the printing paper 1 will be described with reference to FIG. The printing paper 1 includes a plurality of half-cut lines 7 formed in advance so as to surround the printing portion 5 on the print 1A as described above. Further, the printing paper 1 is provided with a plurality of detection holes 8 formed in advance, and the detection holes 8 are formed at intervals l corresponding to one print 1A.

Have. In this way, the print paper 1 is provided with the half-cut line 7 in advance.

In the present embodiment, the half-cut line 7 provided on the printing paper 1 reaches from the PET layer 4 to the adhesive layer 3, whereby the seal 5A including the printing portion 5 is peeled from the print 1A along the half-cut line 7. In that case, the adhesive layer 3 moves to the seal 5A side.

In addition, when the half-cut line 7 is formed only on the PET layer 4 and the seal 5A including the printing portion 5 is peeled from the print 1A along the half-cut line 7, the adhesive layer 3 may be left on the print 1A side. Good. In this case, an adhesive layer may be provided on the surface of the target object to which the seal 5A is bonded, and the seal 5A can be bonded onto the surface of the target object.

The printing paper 1 having the above-mentioned configuration has the half-cut line 7 formed in advance, and may have curl habit. The printing paper 1 having such a curl is skewed in the printer device 10, and as a result, the detection hole 8 cannot be correctly detected, which makes it impossible to cut the printing paper 1 accurately. There is a nature.

The printer device 10 according to the present embodiment has a function of appropriately correcting the skew of the printing paper 1 and accurately cutting the printing paper 1 by having the following configuration.

Such a printer device 10 includes a printing paper supply unit 11 that supplies the printing paper 1 described above, and a printing unit 15A that performs printing on the printing paper using the ink ribbon 20. A pair of guide rollers 12a and 12b for guiding the print sheet 1 are provided between the print sheet supply unit 11 and the printing unit 15A, and the print sheet is conveyed in the downstream side of the pair of guide rollers 12a and 12b. A pair of grip rollers 13a and 13b for transporting to L1 are provided.

A detection hole sensor (also simply referred to as a detection sensor) 18 that detects the detection hole 8 of the printing paper 1 is provided on the downstream side of the printing unit 15A, and the printing paper 1 is printed on the downstream side of the detection hole sensor 18. A cutter 19 is provided that cuts at intervals l corresponding to one sheet of 1A to produce each print 1A.

Of these, the printing paper supply unit 11 has a supply unit main body 11A made of a cylindrical reel and a pair of flanges 11a provided at both ends of the supply unit main body 11A, and a drive gear 11b is provided on the outer periphery of each flange 11a. Are formed (see FIGS. 2A and 2B).

The printing unit 15A includes a thermal head 15 that prints on the printing paper 1 by using the ink ribbon 20, and a platen roller 16 that is provided to face the thermal head 15.

The printing unit 15A also includes an ink ribbon supply unit 21 that supplies the ink ribbon 20 in the transport direction L2, and an ink ribbon winding unit 22 that winds the ink ribbon 20.

Of these, the ink ribbon 20 has an ink layer arranged on one surface and a support layer arranged on the other surface.

Further, the printer device 10 has a control unit 30 for driving and controlling the printing paper supply unit 11, the pair of grip rollers 13a and 13b, the printing unit 15A, and the cutter 19, and this control unit 30 detects by the detection hole sensor 18. A detection signal is sent.

The printing paper supply unit 11 has a supply unit main body 11A and a pair of flanges 11a that are provided at both ends of the supply unit main body 11A and that include a drive gear 11b. In this case, the pair of flanges 11a of the printing paper supply unit 11 and the pair of grip rollers 13a and 13b are connected via a connection gear (not shown).

Further, of the pair of grip rollers 13a and 13b, one grip roller 13a is driven by a pulse motor 13A, and the pulse motor 13A accurately moves the pair of grip rollers 13a and 13b by a desired carry amount. It can be transported well.

The one grip roller 13a is driven by the pulse motor 13A, while the other grip roller 13b is rotated by the one grip roller 13a via the printing paper 1.

Further, the guide rollers 12a, 12a also rotate along with the movement of the printing paper 1 being conveyed.

Next, the operation of the present embodiment having such a configuration will be described with reference to the flowchart shown in FIG.

First, the control unit 30 controls the printer device 10 in the initial operation mode.

Specifically, the control unit 30 controls the pair of grip rollers 13a and 13b to convey the print sheet 1 in the conveying direction L1 (see FIG. 1A). In this case, the pair of grip rollers 13a and 13b send the printing paper 1 to the cutter 19 side, and the cutter 19 initially cuts the printing paper 1 from the front end by a predetermined length.

When the printing paper 1 is initially cut by the cutter 19, the desired initial cutting length is the length necessary to correct the skew of the printing paper 1 and is the length determined in advance by experiments. In the embodiment, for example, the length is equivalent to 2 to 6 prints 1A, for example, (2 to 6)×1 (see FIG. 6).

2A to FIG. 2B and FIG. 3A to FIG. 3B, when the print sheet 1 skews, the behavior of the print sheet when correcting this skew will be described.

FIG. 2A shows a state in which the printing paper 1 is conveyed in the correct direction. As described above, the detection holes 8 are formed in the printing paper 1 at predetermined intervals l in advance, and the half cut lines 7 surrounding the printing portion 5 are formed in advance. For this reason, the curl habit is generated due to the manufacturing and storage conditions of the printing paper 1, and the printing paper 1 skews when the printing paper 1 set in the printing paper supply unit 11 is conveyed (see FIG. 2B). ..

By the way, in the printer device 10, the peripheral speed D of the pair of grip rollers 13a and 13b is slightly higher than the peripheral speed d of the printing paper supply unit 11. As described above, the grip roller 13a and the supply unit main body 11A are connected via the connecting gear, but the connecting gear includes the torque limit. Therefore, when the print sheet 1 is conveyed along the conveyance direction L1 by the pair of grip rollers 13a and 13b, the force from the print sheet 1 is conveyed when the grip rollers 13a and 13b and the print sheet 1 are not loosened. As a result, the supply unit main body 11A rotates. At this time, tension is generated on the printing paper 1 between the printing paper supply unit 11 and the pair of grip rollers 13a and 13b.

On the other hand, when the printing paper 1 is returned in the direction opposite to the transport direction L1, the pair of grip rollers 13a and 13b and the printing paper are not printed due to the difference in peripheral speed between the pair of grip rollers 13a and 13b and the printing paper supply unit 11. The slack of the printing paper 1 occurs between the supply unit 11.

In addition, when a new printing paper 1 is set in the printing paper supply unit 11 and the printing paper 1 is conveyed in the conveyance direction L1 in the initial operation mode, the printing paper 1 may be skewed. The slack of the printing paper 1 occurs between the grip rollers 13a and 13b and the printing paper supply unit 11 (see FIG. 3A).

In FIG. 3A, the printing paper 1 is skewed toward the upper right direction, and the printing paper 1 is loosened below the guide rollers 12a and 12b.

When the print sheet 1 is conveyed in the L1 direction in this state, the pair of grip rollers 13a and 13b and the print sheet supply unit 11 are separated from each other due to the difference in peripheral speed between the pair of grip rollers 13a and 13b and the print sheet supply unit 11. Among the printing papers 1 in between, the printing paper 1 is pulled especially in the lower left part of the printing paper 1, and the slack of the printing paper 1 is eliminated.

When the looseness of the printing paper 1 is eliminated in the lower left portion of the printing paper 1 in this way, downward tension F is applied to the printing paper 1 in the lower left portion of the printing paper 1 (see FIG. 3B).

When the tension F is applied to the lower left portion of the printing paper 1 that is transported along the transportation direction L1, the printing paper 1 as a whole moves in the M direction in FIG. 3B.

When the print sheet 1 is conveyed along the conveyance direction L1 in this state for a while, the print sheet 1 obliquely moving to the upper right gradually comes to face right above (correct direction), and at the same time, the pair of grip rollers 13a, The slack generated in the printing paper 1 between the printing paper supply unit 11 and 13b is eliminated not only in the lower left portion of the printing paper 1 but also in the lower right portion.

The extent to which the printing paper 1 is conveyed from the skew of the printing paper 1 to the right direction has been previously determined by experiments.

The result of the experiment is shown in FIG. FIG. 4 is a diagram showing the degree of skew when the print sheet 1 is continuously conveyed from the skewed state of the print sheet 1 shown in FIG. 3A.

As shown in FIG. 4, when the leading edge of the printing paper 1 is skewed to the left or right by a maximum of +1.5 mm or a maximum of −1.5 mm with respect to the reference position facing the correct direction, the printing paper 1 is conveyed. It can be seen that, by continuing to carry out, the skew of the printing paper 1 is corrected to the range of approximately ±0.25 mm from the reference position at the leading edge position of the third sheet, which is advanced by two sheets of the print 1A.

Further, it can be seen that by continuing to convey the print sheet 1, the print sheet 1 approaches the substantially reference position after the six sheets of the print 1A have been conveyed from the cutter 19.

Therefore, according to the present embodiment, the pair of grip rollers 13a and 13b are drive-controlled by the control unit 30, and the skewed printing paper 1 is continuously transported to transport the printing paper 1 to the cutter 19. Next, the printing paper 1 equivalent to 2 to 6 sheets in terms of the length of the print 1A in the conveying direction from the cutter 19 is initially cut by the cutter 19 which is drive-controlled by the control unit 30. After that, the detection hole sensor 18 detects the detection hole 8 of the printing paper 1, cuts the printing paper 1 by one print at a predetermined position, and ends the initial operation mode.

As a result, in the normal operation mode described later, the printing unit 15A performs printing on the printing paper 1 after the skewed printing paper 1 has been corrected in the correct direction, and the printing paper 1 that has already been printed is printed. With the cutter 19, the print 1A can be produced by cutting the print 1A one by one.

In the initial operation mode, the control unit 30 continues to convey the printing paper 1 by the pair of grip rollers 13a and 13b, but during this period, the printing by the printing unit 15A is stopped and the detection hole sensor 18 detects the initial cutting position. Stop except for the detection hole 8 for the last print 1A.

Next, the control unit 30 executes the normal operation mode. In the normal operation mode, first, the printing paper 1 cut in the initial operation mode by the cutter 19 is returned by the pair of grip rollers 13a and 13b whose drive is controlled by the control unit 30. Next, the leading edge of the initially cut printing paper 1 reaches the printing unit 15A.

After that, the control unit 30 controls the printing unit 15A, printing is performed on the printing paper 1 by the printing unit 15A, and the printed printing paper 1 is detected by the pair of grip rollers 13a and 13b on the detection hole sensor 18 side. Be transported to.

When the detection hole sensor 18 detects the detection hole 8 of the printing paper 1, a signal from the detection hole sensor 18 is sent to the control unit 30. Next, the control unit 30 drives and controls the cutter 19 based on the signal from the detection hole sensor 18 and cuts the printing paper 1 for each one of the prints 1A. In this way, the prints 1A can be produced one by one from the printed printing paper 1.

As described above, according to the present embodiment, in the initial operation mode, the cutter 19 initially sets a desired length from the leading edge of the skewed printing paper 1, for example, a length corresponding to 2 to 6 prints 1A. Disconnect. As a result, the printing unit 15A prints on the printing paper 1 after the skewed printing paper 1 is corrected in the correct direction, and the cutter 19 cuts the print 1A one by one to print the print 1A. Create. In this case, printing can be performed on the printing paper 1 that has been corrected in the correct direction, and the detection hole 8 of the printing paper 1 can be detected by the detection hole sensor 18. Therefore, the detection hole 8 of the printing paper 1 after being corrected in the correct direction can be accurately detected by the detection hole sensor 18, and the wrong position of the printing paper 1 can be detected by the cutter 19 due to the malfunction of the detection hole sensor 18. Without cutting, the printing paper 1 can be cut accurately by the cutter 19 to obtain a high-quality print 1A.

In the above embodiment, the example in which the control unit 30 initially cuts the printing paper 1 from the leading end thereof by a length corresponding to 2 to 6 sheets of the print 1A in the initial operation mode has been described. The length is not limited to the length corresponding to 2 to 6 prints 1A, and can be determined by performing various experiments in advance.

Further, the length of the initial cutting does not necessarily need to be based on the length of the print 1A. For example, the skewed printing paper 1 is corrected in the correct direction based on the results of experiments performed in advance, such as 10 cm or 30 cm. It can be set as the required length.

Further, an example in which the detection hole 8 is provided as the detection unit on the printing paper 1 and the detection hole sensor 18 is provided as the detection sensor for detecting the detection hole 8 is shown, but the present invention is not limited to this, and the detection unit is provided instead of the detection hole 8. As the detection sensor, a detection sensor that optically detects the detection mark may be used as the detection sensor.
