The control unit 60 includes a transport control unit 65, a suction control unit 66, a print control unit 67, and a stamping control unit 68.
, A first correction unit 69, and a second correction unit 70.

The transport control unit 65 drives the transport motor 52 to transport the label paper 5 by the transport mechanism 10. The suction control unit 66 drives the printing unit side suction pump 15 and the processing unit side suction pump 30 to perform suction through the printing unit side platen 13 and the processing unit side platen 28.

Here, the transport control unit 65 performs a cueing operation for matching the print start position on the label 4 with the print position A based on the output from the label position detector 24 and the print data. In the cueing operation, the transport control unit 65 transports the label paper 5 until the label position detector 24 detects the black mark BM.

The print control unit 67 drives the print head 12 and the print unit side carriage motor 23 based on the print data, and prints the print data on the label paper 5 on the transport path 9. More specifically, the print control unit 67 drives the print head 12 while driving the print unit side carriage motor 23 to move the print head 12 in the main scanning direction Y, and directs the ink toward the label 4. Discharge. Thus, the print control unit 67 prints the print data at the print position A.

The stamping control unit 68 includes a stamping data generation unit 71 and a drive control unit 72. The die-cut data generation unit 71 generates die-cut data based on the print data. In the present example, the stamping control unit 68 first obtains the print area P on the label 4 based on the print data. Next, the stamping data generation unit 71 gives a margin of the first dimension L1 to the acquired print area P on the upstream side and the downstream side in the transport direction X, and on both left and right sides in the main scanning direction Y. An area provided with a margin of the second dimension L2 is defined as a stamped area C (see FIG. 1). After that, the cutout data generation unit 71 generates the cutout data based on the defined contour of the cutout area C. The die-cut data is the same data as the print data when the outline of the die-cut area C is printed.

The drive control unit 72 drives the wire dot head 27 (wire pin moving mechanism 42) and the processing unit side carriage motor 38 based on the punching data, and hits the wire pins 41 on the label paper 5 on the transport path 9 to drive the wire pins 41. Then, the label paper 5 is die-cut. More specifically,
The drive control section 72 drives the processing section side carriage motor 38 to drive the wire dot head 2.
While moving 7 in the main scanning direction Y, the wire dot head 27 is driven to project the wire pins 41 toward the label paper 5. As a result, the drive control unit 72 cuts the label sheet 5 at the cutting position B.

Here, the transport control unit 65 transports the label sheet 5 from the printing position A to the stamping position B based on the stamping data. More specifically, as shown in FIG. 4, when the die-cut data generation unit 71 generates the die-cut data, the conveyance control unit 65 sets the separation distance D between the print position A and the die-cut position B. , The specified transport amount M of the label paper 5 is calculated based on the dimension E between the black mark BM and the printing start position and the first dimension L1 which is the width of the margin in the transport direction X with respect to the print area P. The label paper 5 is transported by the specified transport amount M. The specified transport amount M is obtained by the following equation (1).
M = DE + L1 (1)

When the label paper 5 is transported from the printing position A toward the die-cutting position B by the specified transport amount M, the first correction unit 69 performs a driving position U1 on the label paper 5 where the wire pins 41 are driven, The deviation in the transport direction X from the target hitting position U2 set in advance on the label paper 5 is corrected.

In the present example, the first correction unit 69 controls the transport mechanism 10 based on the transport direction deviation amount α1 between the hitting position U1 and the target hitting position U2 of the label paper 5 in the transport direction X, and The transport amount of the label paper 5 between A and the die-cutting position B is corrected. That is, the driving position U
If the print area P and the die-cut area C on the label sheet 5 are shifted in the transport direction X due to the shift of the print position A from the target hitting position U2, the first correction unit 69 sets the print position A and the die-cut position. By adjusting the amount of conveyance between B and B, the die-cut area C is moved in the conveyance direction X, and the deviation is corrected.

More specifically, the correction amount M1 is obtained by adding the shift amount α1 in the transfer direction between the hitting position U1 and the target hitting position U2 in the transfer direction X to Expression (1), and the printing by the transfer control unit 65 is performed. The transport amount of the label paper 5 between the position A and the die-cutting position B is defined as a corrected transport amount M1. That is, the first correction unit 69 corrects the specified transport amount M by the transport control unit 65 to a corrected transport amount M1 calculated by the following equation (2). The transport direction deviation amount α1 is a negative value when the driving position U1 is located downstream of the target driving position U2 in the transport direction X, and is negative when the driving position U1 is located upstream. , A positive value.
M1 = DE−L1 + α1 (2)

Here, the first correction unit 69 includes an input unit 69a that receives an input of the transport direction deviation amount α1. The input unit 69a receives the transport direction deviation amount α1 input to the control unit 60 from the external device via the communication unit 61. Note that an input unit 69a of the first correction unit 69 may be provided on the operation panel of the printer 1, and an input of the transport direction deviation amount α1 from the input unit 69a may be received.

The transport direction shift amount α1 is obtained from the printing result and the die-cutting result of actually performing the printing operation and the die-cutting operation on the label paper 5. That is, the transport direction deviation amount α1 between the print area P and the die-cut area C is visually measured and acquired from the print result and the die-cut result of the label sheet 5, and this is obtained as a result of the hitting position U1 and the target hitting position U2. This is the amount of displacement in the transport direction. A scanner or the like can be used to obtain the transport direction deviation amount α1.

When the label sheet 5 is conveyed from the printing position A toward the die-cutting position B by the specified carry amount M or the corrected carry amount M1, the second correction unit 70 urges the wire pins 41 on the label paper 5 A deviation in the main scanning direction Y between the setting position U1 and a target setting position U2 set in advance on the label sheet 5 is corrected.

In the present example, the second correction unit 70 performs the wire pin movement by the die removal control unit 68 based on the shift amount α2 between the hitting position U1 of the label sheet 5 in the main scanning direction Y and the target hitting position U2 in the main scanning direction. The drive timing of the mechanism 42 is corrected. That is, if the printing area P and the die-cut area C on the recording paper are shifted in the main scanning direction Y due to the shifting of the hitting position U1 from the target hitting position U2, the wire dot moving in the main scanning direction Y The stamping area C is moved in the main scanning direction Y by shifting the driving timing of the wire pins in the head 27.

For example, as shown in FIG. 5, when the hitting position U1 is located on one side Y1 in the main scanning direction Y with respect to the target hitting position U2, the wire dot head 27 is moved to the other side in the main scanning direction Y. While moving to the side Y2, the timing of driving the wire pin moving mechanism 42 (the timing of energizing the drive coil 48) is delayed. Then, when the wire dot head 27 is moving to one side Y1 in the main scanning direction Y, the drive timing of the wire pin moving mechanism 42 (the timing of energizing the drive coil 48) is advanced. Thereby, the driving position U1 of the wire pin 41 on the label paper 5 is moved to the other side Y2 in the main scanning direction Y, and the stamping area C is moved.
Is moved to the other side Y2 in the main scanning direction Y.

Further, for example, the hitting position U1 is different from the target hitting position U2 in the other side Y in the main scanning direction Y.
2, the timing of driving the wire pin moving mechanism 42 (the timing of energizing the drive coil 48) when the wire dot head 27 is moving to the other side Y <b> 2 in the main scanning direction Y. Hasten. When the wire dot head 27 is moving to one side Y1 in the main scanning direction Y, the drive timing of the wire pin moving mechanism 42 (the drive coil 4
8 is energized). Thereby, the wire pins 4 on the label paper 5
By moving the hitting position U1 to one side Y1 in the main scanning direction Y, the stamping area C is moved to one side Y1 in the main scanning direction Y. The time for shifting the drive timing of the wire pin moving mechanism 42 is a time corresponding to the amount of deviation α2 in the main scanning direction.

Here, the second correction unit 70 includes an input unit 70a that receives an input of the deviation amount α2 in the main scanning direction. The input unit 70a receives a main scanning direction shift amount α2 input to the control unit 60 from an external device via the communication unit 61. Note that an input unit 70a of the second correction unit 70 may be provided on the operation panel of the printer 1, and an input of the transport direction deviation amount α2 from the input unit 70a may be received.

In the main scanning direction shift amount α2, the printing operation and the die cutting operation on the label paper 5 are actually performed,
It is obtained from the printing result and the die cutting result. That is, the shift amount α2 in the main scanning direction between the print area P and the die cut area C is visually measured and obtained from the print result and the die cut result of the label paper 5, and this is obtained by hitting the target position U1 and the target hit position U2. In the main scanning direction. A scanner or the like can be used to obtain the main scanning direction shift amount α2.

(Printing, stamping operation)
FIG. 6 is a flowchart of the printing and die cutting operations by the printer 1. In the example shown in FIG. 6, a printing operation and a die-cutting operation on the label paper 5 are performed in advance, and the transport direction deviation amount α1 and the main scanning direction deviation amount α2 are obtained. Also, the acquired transport direction deviation amount α1 and main scanning direction deviation amount α2 are input to the printer 1 from an external device (step ST).
1).

When print data is supplied from an external device to the printer 1 (step ST2), the printer 1 drives the transport motor 52 to transport the label paper 5 intermittently along the transport path 9. In addition, the printer 1 drives the printing unit side suction pump 15 and the processing unit side suction pump 30 to perform suction through the printing unit side platen 13 and the processing unit side platen 28 (step ST3).

Thereafter, the printer 1 drives the print head 12 and the printing unit side carriage motor 23 based on the print data, and performs a printing operation of printing the print data on the label paper 5 on the transport path 9 at the print position A (step). ST4). In addition, the printer 1 generates the die-cut data based on the print data and performs a transport operation of transporting the label paper 5 toward the die-cut position B.

In the transport operation, the printer 1 transports the label paper 5 by the corrected transport amount M1 obtained by correcting the specified transport amount M based on the transport direction deviation amount α1 (step ST5). Thereby, the driving position U1 on the label sheet 5 where the wire pin 41 is driven is moved in the transport direction X.
The target hitting position U2 is made to coincide.

Thereafter, the printer performs a die-cutting operation of die-cutting the label paper 5. That is, the printer 1 uses the wire dot head 27 (the wire pin moving mechanism 4) based on the die-cut data.
2) and drive the processing section side carriage motor 38 to strike the wire pins 41 on the label paper 5 on the transport path 9. (Step ST6).

In the stamping operation (strike operation), the printer shifts the drive timing of the wire pin moving mechanism 42 in the wire dot head 27 by a time corresponding to the deviation amount α2 in the main scanning direction. Thereby, the striking position U1 on the label sheet 5 where the wire pins 41 are struck is matched with the target striking position U2 in the main scanning direction Y (step ST61).
.

According to this embodiment, the wire pins 41 of the wire dot head 27 are punched on the label paper 5 on the transport path 9 and the label paper 5 is die-cut. Further, the label dot 5 is cut out by controlling the wire dot head 27 based on the cut-out data generated based on the print data. Therefore, according to the printer 1 of the present embodiment, the label paper 5 can be cut out in a shape corresponding to the print area P based on the print data. Further, in this example, since the wire dot head 27 is used for cutting the label paper 5, the wire pin moving mechanism 42 can be easily controlled based on the cutting data based on the print data.

Further, in this example, the printing area P and the stamping area C on the label sheet 5 are shifted in the transport direction X by the shift of the hitting position U1 at which the wire dot head 27 hits the wire pin 41 with respect to the target hitting position U2. In the case of deviation, the transport amount of the label sheet 5 from the printing position A to the die-cutting position B is corrected from the specified transport amount M to the corrected transport amount M1. Thereby, the transport direction X
In, the hitting position U1 can be matched with the target hitting position U2.

Further, in this example, the printing area P and the stamping area C on the label paper 5 are shifted in the main scanning direction Y by the shift of the hitting position U1 at which the wire dot head 27 hits the wire pin 41 with respect to the target hitting position U2. In the case of deviation, the drive timing of the wire pin moving mechanism 42 in the wire dot head 27 that moves in the main scanning direction Y is shifted to move the die-cut area C in the main scanning direction Y. Thereby, the hitting position U1 in the main scanning direction Y can be matched with the target hitting position U2.

(Other embodiments)
The first correction unit 69 controls the transport mechanism 10 based on the amount of deviation between the hitting position U1 and the target hitting position U2 in the transport direction X of the label paper 5, and the The printing start position may be moved in the transport direction X.

That is, if the printing area P and the die-cut area C on the label sheet 5 are shifted in the transport direction X due to the shift of the hitting position U1 from the target hitting position U2, Can be moved in the transport direction X to adjust the positional relationship between the print area P and the die-cut area C. This makes it possible to correct the misalignment between the printing area P and the stamping area C.

Further, the second correction unit 70 corrects the drive timing of the print head 12 to the print control unit 67 based on the deviation amount between the hitting position U1 and the target hitting position U2 of the label paper 5 in the main scanning direction Y. It is good also as what makes it.

That is, when the printing area P and the stamping area C on the label paper 5 are shifted in the main scanning direction Y due to the shift of the hitting position U1 from the target hitting position U2, the movement is performed in the main scanning direction Y. The print area P is moved in the main scanning direction Y by shifting the drive timing of the print head 12. This makes it possible to correct a deviation between the hitting position U1 and the target hitting position U2.

Further, in the above example, the stamping data generation unit 71 determines the stamping area C based on the print data.
However, predetermined die-cutting data may be registered in advance, and the die-cutting operation may be performed based on the registered die-cutting data during the die-cutting operation. Furthermore, the die cutting section 8 punches the wire pins 41 onto the label paper 5 while moving the wire dot head 27 in the main scanning direction Y to die-cut the label paper 5. 9 in the main scanning direction Y. That is, the wire dot head 27 may be a line head.
