Then, cutting position data indicating where the sheet material 8 is to be cut is set. It should be noted that, based on the printing position data used at the time of printing, the cutting position data is set in advance, and the cutting position data is corrected and set according to the calculated printing position of the image N1. May be. With this configuration, even when the shape of the image N1 is slightly deformed as the ink is dried, the cutting process can be performed at a position corresponding to the deformed shape. It becomes possible. For example, even when the rear part of the image N1 is deformed so as to spread with respect to the front part (deformed into a trapezoidal shape), the keystone correction for matching the cut position with the image N1 can be performed.
- step S104 based on the set cutting position data, the cutting unit 50 is moved left and right, and the sheet material 8 is fed back and forth while the cutter blade 53 is bitten into the sheet material 8 to thereby draw the contour of the image N1. Cut along.
- the cutting apparatus 1 has a configuration in which after the printing is completed, the sheet material 8 is cut back from the image N1 printed at the rear end without back-feeding the sheet material 8 backward as in the related art. ing. Therefore, by reducing the feeding amount of the sheet material 8 in the front-rear direction and the frequency of feeding the sheet material 8, the positional deviation of the sheet material 8 that easily occurs during feeding is reduced, and the sheet material 8 and the cutter blade 53 Position accuracy can be ensured. Conventionally, a large displacement occurs when backfeeding backward, and this causes a detection error in which a registration mark cannot be detected because the registration mark is not positioned below the registration mark detection unit 54, and a series of operations is interrupted. There was a thing. On the other hand, in the cutting apparatus 1 according to the present invention, since the occurrence of misalignment can be reduced as described above, a series of operations can be executed efficiently without causing such a detection error.
- the cutting apparatus 1 is configured to perform cutting in order from the image printed at the rear end (last), the work time required for the back feed can be shortened, and printing and cutting processing can be performed. It is possible to improve the work efficiency by shortening the time required for a series of work.
- step S105 the process proceeds to step S105, and after the cutting process on the image N1 is completed, the cutting unit 50 is moved to the right, and in the same manner as the image N1, the first reference positions t1 to t4 of the registration marks T1 to T4 corresponding to the image N2. 4 Reference position t4 is calculated. Cut position data is set based on the calculated first reference position t1 to fourth reference position t4, and cut processing is performed along the contour of the image N2.
- step S106 the image A1 printed on the front end is cut, and then the process proceeds to step S107, where the image A2 printed on the right side of the image A1 is cut. finish.

- the position closest to the completion position among the plurality of registration marks corresponding to the adjacent images according to the completion position where the cutting process has been completed (the position where the feed amount of the sheet material 8 forward and backward can be reduced).
- Position detection is performed in order from the registration mark. By doing so, the feed amount of the sheet material 8 in the front-rear direction can be reduced, the positional deviation of the sheet material 8 can be reduced, and the positional accuracy of the sheet material 8 and the cutter blade 53 can be maintained.
- the case where the present invention is applied to the cutting apparatus 1 that includes the printer head 62 and can perform printing is exemplified.
- the cutting that does not include the printer head 62 and can only perform the cutting process is also applicable to the device.
- the configuration in which the four L-shaped registration marks T1 to T4 are printed for one image has been described as an example, but the present invention is not limited to this configuration.
- three registration marks may be printed for one image, and the shape of the registration marks is not limited to an L shape.
- a configuration has been described in which four registration marks T1 to T4 are printed for one image, and the positions of the registration marks T1 to T4 are detected to calculate the print positions of the images. It is not limited to this configuration.
- a configuration is possible in which the position of an arbitrary detected first registration mark among the four registration marks T1 to T4 is set as the origin.
- a method of detecting a second registration mark that is printed in the left-right direction with respect to the detected first registration mark, and performing correction in the left-right direction and inclination correction, or for the detected first registration mark It is also possible to detect the second registration marks printed in the front-rear direction and perform front-rear direction correction and tilt correction. Further, by detecting a second registration mark printed diagonally with respect to the detected first registration mark, or by detecting the first to third registration marks, correction in the horizontal direction, correction in the front-rear direction, and A method of performing tilt correction is also possible.
