Description

The present invention relates to a cutting device.

Conventionally, a cutting device for cutting a medium made of paper, a resin sheet, or the like has been known. Further, a cutting device having a function of printing on a medium is known. For example, Patent Document 1 discloses such a cutting device. In such a cutting device, for example, after printing a plurality of images on a medium, a process of cutting the periphery of each image on the medium with a cutter is performed. The position of the cut line with respect to each image is predetermined, and in order to perform high-precision cutting, it is necessary to minimize the positional deviation between the trajectory followed by the cutter and the predetermined cut line.

Patent Document 1 discloses that when an image is printed on a medium, a plurality of crop marks are printed around each image. Then, at the time of cutting, the positions of the crop marks are detected, and the cutting head is positioned based on the positions of the crop marks. By using the crop marks printed around each image in this way, the positioning of the cutting head can be performed with high accuracy. As a result, the cutting accuracy can be improved.

Japanese Unexamined Patent Publication No. 2001-260443

By the way, if a plurality of crop marks are printed around each image and the position of the crop mark is detected for each image during cutting, the accuracy of cutting is improved, but it takes a lot of time for cutting. It takes.

Therefore, as shown in FIG. 10, instead of printing the crop marks on the outside of the four corners of each image 211, it is conceivable to print the crop marks C on the four corners of the rectangular area 216 including all the images 211. As a result, the time required to detect the position of the crop mark C can be shortened. However, if the number of crop marks C used for positioning the cutting head is small, the accuracy of positioning with respect to each image 211 may be lowered when the cutting head is cut, and an error may occur in the cutting position.

The following items can be considered as causes of such an error. In the cutting device, the correction amount for the theoretical position of the crop mark C is calculated based on the detection of the position of the crop mark C. Positioning of the cutting head with respect to each image 211 is performed based on the above correction amount. However, when the medium moves on the platen, the positional relationship between the medium and the platen may shift, and the positional shift may occur between the cutting head and each image 211 on the medium. Reasons for the misalignment of the medium moving on the platen include friction between the platen and the medium, slippage of the pinch roller in contact with the medium, expansion and contraction of the medium due to temperature and humidity, and the like. As the number of images 211 increases, the area of the entire image becomes large, so that an error in the cutting position is likely to occur.

The present invention has been made in view of the above points, and an object of the present invention is to provide a cutting device capable of achieving both a reduction in cutting time and an improvement in cutting accuracy in a well-balanced manner.

The cutting device according to the present invention includes a support base, a cutting head, a first moving mechanism, a second moving mechanism, a cropmark detecting device, and a control device. The support base supports a printed image having a plurality of images and a medium on which a plurality of crop marks are printed. The cutting head cuts the medium supported by the support base. The first moving mechanism moves the cutting head in the main scanning direction. The second moving mechanism moves the medium supported by the support base relative to the cutting head in the sub-scanning direction. The cropmark detection device detects the position of the cropmark. In the plurality of images, in the first rectangular region and the second rectangular region located side by side in a predetermined direction, the first image located in the first rectangular region and the second rectangular region are located in the second rectangular region. At least a second image is included. The plurality of cropmarks are located at the four corners of the first rectangular region and the four corners of the second rectangular region, respectively. The control device includes a storage unit, a selection unit, a detection unit, a correction amount calculation unit, a determination unit, a determination unit, and a cutting control unit. In the storage unit, the theoretical position, which is the theoretical position of each of the plurality of cropmarks with respect to the support base, is stored in advance. The selection unit sets the first rectangular area as the selection area, and sets the plurality of crop marks located at the four corners of the selection area as the selection crop marks. The detection unit detects the position of the selected crop mark by the crop mark detection device. The correction amount calculation unit calculates a correction amount with respect to the theoretical position at the position of the selection crop mark detected by the detection unit. The determination unit determines whether or not the correction amount calculated by the correction amount calculation unit is equal to or less than a predetermined allowable correction amount. When the determination unit determines that the correction amount is equal to or less than the allowable correction amount, the selection unit sets a region in which the first rectangular region and the second rectangular region are combined as the selection region. The plurality of crop marks located at the four corners of the selected area are set as the selected crop marks. In the storage unit, the previous area, which is the selected area set last time, is stored. When the determination unit determines that the correction amount is larger than the allowable correction amount, the determination unit sets the previous area stored in the storage unit as the determination area and is located at the four corners of the previous area. The crop mark is set as the determination crop mark. The cutting control unit positions the cutting head based on the determination crop mark, and cuts the medium in the determination region.

According to the cutting device, the correction amount calculated by the correction amount calculation unit is calculated based on the actual position of the selected crop mark, and thus can be said to be an accurate value. The range to be cut at one time is determined based on this correction amount. If the correction amount is less than or equal to the allowable correction amount, the selection area is set again so as to widen the cutting range. On the other hand, when the correction amount is larger than the allowable correction amount, the cutting accuracy is lowered, so that the cutting is performed in the range corresponding to the previous crop mark, which is the previously selected crop mark. Therefore, the cutting time can be shortened within the range of acceptable cutting accuracy. Therefore, it is possible to achieve both a reduction in cutting time and an improvement in cutting accuracy in a well-balanced manner.

According to the present invention, it is possible to provide a cutting device capable of achieving both a reduction in cutting time and an improvement in cutting accuracy in a well-balanced manner.

The cutting head 40 is supported by the guide rail 18 via the carriage 41. The carriage 31 and the carriage 41 are movably engaged with the guide rail 18 in the main scanning direction Y.

As shown in FIG. 2A, a cutter 43 is attached to the carriage 41 via a solenoid 42. When the solenoid 42 is turned ON / OFF, the cutter 43 moves in the vertical direction and comes into contact with the medium 5 or separates from the medium 5. The cutting head 40 is provided with a sensor 45, which is an example of a crop mark detecting device for detecting crop marks C1 to C4 (see FIG. 4) described later. The type of the sensor 45 is not particularly limited. For example, as the sensor 45, various sensors conventionally used such as an optical sensor can be preferably used. A connecting member 44 composed of magnets is fixed to the right side portion of the carriage 41.

In the present embodiment, a belt 19 extending in the main scanning direction Y is fixed to the upper part of the back surface of the carriage 41. The belt 19 is connected to the scan motor 62 (see FIG. 3). As the scan motor 62 rotates, the belt 19 travels in the main scanning direction Y. As a result, the carriage 41 moves in the main scanning direction Y. In the present embodiment, the carriage 41, the guide rail 18, the belt 19, and the scan motor 62 form a first moving mechanism that moves the printing head 30 and the cutting head 40 in the main scanning direction Y.

The carriage 31 of the print head 30 supports a recording head 32 having a plurality of nozzles (not shown) for ejecting ink. Here, five recording heads 32 are supported by the carriage 31. The five recording heads 32 eject five different colors, such as yellow ink, magenta ink, cyan ink, black ink, and white ink. However, the number of recording heads 32 is not limited to five. Further, the color of the ink ejected by the recording head 32 is not limited at all.

A connecting member 34 made of a magnet is provided on the left side portion of the carriage 31. The connecting member 34 is detachably connected to the connecting member 44 of the cutting head 40.

FIG. 4 is a plan view of the medium 5 on which the plurality of images 111 and the plurality of crop marks C1 to C4 are printed. Here, as shown in FIG. 4, an operation in which the cutting device 100 prints a plurality of images 111 and a plurality of crop marks C1 to C4 on the medium 5 and further cuts the periphery of each image 111 will be described. In the following description, the plurality of images 111 are collectively referred to as a printed image 110. The printed image 110 has a plurality of images 111. In the present embodiment, the "image" is an image formed on the medium 5 by the print head 30, and the content thereof is not particularly limited. Further, the "image" includes characters, symbols, figures, photographs and the like. Here, the contour lines of the plurality of images 111 indicate the cut lines 113 cut by the cutting head 40. However, the cut line 113 is not limited to the contour line of the image 111.

Here, for one medium 5, three rectangular regions 115 are set along the main scanning direction Y, and three rectangular regions 115 are set along the sub-scanning direction X. Therefore, a total of nine rectangular regions 115 are set in the medium 5 of FIG. The image 111 is located within these nine rectangular regions 115. Here, the area in which all the rectangular areas 115 are combined is referred to as the total area 116. The entire area 116 is a rectangular area including the printed image 110. In the present embodiment, three images 111 are printed in the main scanning direction Y and three images 111 are printed in the sub scanning direction X on one medium 5. The number of rectangular regions 115 and the number of images 111 are not particularly limited. The plurality of images 111 may be the same type of image or may be different types of images. In the following description, the main scanning direction Y of the medium 5 is referred to as a “row”, and the sub-scanning direction X is referred to as a “column”.

Here, for convenience of explanation, the lines from the front to the back of the medium 5 are referred to as the first line, the second line, and the third line in order. In the plurality of rectangular regions 115, the regions 115A1, 115A2, 115A3 are designated in order from the right of the first row, the regions 115B1, 115B2, 115B3 are designated in order from the right of the second row, and the regions 115C1 and are ordered from the right of the third row. Let it be 115C2 and 115C3. In the present embodiment, the region including the regions 115A1 and 115A2 is an example of the first rectangular region of the present invention, and the image 111 in the region 115A1 is an example of the first image of the present invention. The region 115A3 is an example of the second rectangular region of the present invention, and the image 111 in the region 115A3 is an example of the second image of the present invention. Further, the region including the regions 115B1 and 115B2 is an example of the third rectangular region of the present invention, and the image 111 in the region 115B1 is an example of the third image of the present invention. The region 115B3 is an example of the fourth rectangular region of the present invention, and the image 111 in the region 115B3 is an example of the fourth image of the present invention.

In this embodiment, the sizes of the plurality of images 111 are the same. In other words, the length of the main scanning direction Y is the same in the plurality of images 111, and the length of the sub scanning direction X is the same. However, a part of the plurality of images 111 may be different in size from the other part. For example, in a plurality of images 111 arranged in the same row, the length of the main scanning direction Y may be different, and the length of the sub scanning direction X may be the same. Further, for example, in a plurality of images 111 arranged in the same row, the length of the main scanning direction Y may be the same, and the length of the sub-scanning direction X may be different. Similarly, in this embodiment, the sizes of the plurality of rectangular regions 115 are the same. In other words, the length of the main scanning direction Y is the same in the plurality of rectangular regions 115, and the length of the sub scanning direction X is the same. However, a portion of the plurality of rectangular regions 115 may be different in size from the other portion. In this case, for example, in a plurality of rectangular regions 115 arranged in the same row, the length of the main scanning direction Y may be different, and the length of the sub scanning direction X may be the same. Further, for example, in a plurality of rectangular regions 115 arranged in the same row, the length of the main scanning direction Y may be the same, and the length of the sub scanning direction X may be different.

In the present embodiment, image data (not shown) is transmitted to the control device 60 from a computer (not shown) communicatively connected to the control device 60. This image data includes data relating to the printed image 110, that is, data relating to the plurality of images 111, but does not include data relating to the crop marks C1 to C4. The crop marks C1 to C4 are given by the control device 60 at the time of printing. When the image data is transmitted from the computer to the control device 60 in this way, the image print control unit 73 prints the print image 110, and the crop mark print control unit 75 prints a plurality of crop marks C1 to C4. To. The upper and lower parts of FIG. 4 represent the front side and the rear side, respectively. In the cutting device 100, printing is performed while transporting the medium 5 forward. Therefore, printing is performed from the upper side to the lower side of FIG.

When printing, the scan motor 62 is driven to move the print head 30 in the main scanning direction Y, and ink is ejected from each recording head 32 of the print head 30. As a result, the printed image 110 and the crop marks C1 to C4 are printed on one scanning line. When the movement of the print head 30 in the main scanning direction Y is completed, the feed motor 61 is driven to convey the medium 5 to the position of the next scanning line in front of the sub-scanning direction X. When the sub-scanning direction X of the medium 5 is conveyed, the scan motor 62 is driven again and the print head 30 is driven to print the print image 110 and the crop marks C1 to C4 of the next scan line. Hereinafter, the same operation is repeated until the print image 110 and the crop mark are completed.

Here, the printing performed when the medium 5 is conveyed in front of the sub-scanning direction X once is referred to as one printing. In the present embodiment, the printing of the plurality of images 111 and the printing of the plurality of crop marks C1 to C4 are performed in one printing. However, the printing of the plurality of images 111 and the printing of the plurality of crop marks C1 to C4 may be performed by different printing. For example, the printing of the plurality of crop marks C1 to C4 may be performed after the printing of the plurality of images 111, or the printing of the plurality of images 111 may be performed after the printing of the plurality of crop marks C1 to C4. Good.

In this embodiment, as shown in FIG. 4, a plurality of crop marks C1 to C4 are printed at the four corners of each rectangular region 115 on the medium 5. Specifically, in one rectangular region 115, the crop marks C1, C2, C3, and C4 are located at the right front corner, the left front corner, the right rear corner, and the left rear corner, respectively, when viewed from the front of the medium 5. In one rectangular region 115, the crop mark C2 is separated from the crop mark C1 in the main scanning direction Y. The crop mark C3 is separated from the crop mark C1 in the sub-scanning direction X. The crop mark C4 is separated from the crop mark C2 in the sub-scanning direction X, and is separated from the crop mark C3 in the main scanning direction Y.

The cropmarks C1 to C4 are all formed by black circles. However, the shapes of the crop marks C1 to C4 are not limited to circles, and their colors are not limited to black. Here, the dimensions of the crop marks C1 to C4 are the same. However, some of the cropmarks C1 to C4 may be different in shape or size from the other parts.

In the present embodiment, the crop mark printing control unit 75 may print the rectangular mark M1 in addition to the crop marks C1 to C4 in each rectangular area 115 on the medium 5. The rectangular mark M1 has a rectangular shape and is a mark located between the crop mark C1 and the crop mark C2. The rectangular mark M1 is aligned with the crop marks C1 and C2 in the main scanning direction Y. The rectangular mark M1 is formed of black, but its color is not limited to black. The rectangular mark M1 can be omitted.

As described above, after printing the printed image 110 (in other words, a plurality of images 111), the plurality of crop marks C1 to C4, and the plurality of rectangular marks M1 on the medium 5, the cutting head 40 prints the printed images 110 (in other words, a plurality of images 111). The printed image 110 printed on the medium 5 is cut off.

By the way, conventionally, when a plurality of images 111 are printed on the medium 5, the cutting head 40 is positioned for each image 111 by sequentially detecting the crop marks C1 to C4 of each rectangular area 115. .. Then, the image 111 of the medium 5 was cut by the cutting head 40 for each image 111. In this way, when a plurality of images 111 are cut in order using all the crop marks C1 to C4, it takes a lot of time to cut because the positions of all the crop marks C1 to C4 are detected.

However, depending on the type of image 111 to be cut, the cutting accuracy may not be so high. For example, when the cut line 113 is not represented by printing on the medium 5 and the image 111 is formed by cutting the medium 5 (for example, in FIG. 4, the contour line of the image 111 is not represented by printing). In this case), even if the theoretical cut position and the actual cut position deviate from each other, it is considered that the quality is not so affected. In such a case, by keeping the cutting accuracy within an allowable range, it is possible to shorten the cutting time while maintaining the quality.

Therefore, in the present embodiment, when cutting the plurality of images 111 printed on the medium 5, the plurality of images 111 are cut together while maintaining a certain degree of cutting accuracy. By cutting the plurality of images 111 together, the number of crop marks C1 to C4 detected by the sensor 45 (see FIG. 2A) can be reduced. As a result, the cutting time is shortened.

Hereinafter, among the plurality of crop marks C1 to C4 printed on the medium 5, the procedure for determining the crop marks C1 to C4 used in cutting is described in the flowchart of FIG. 5 and the plane of the medium 5 of FIGS. 6 to 9. This will be described with reference to the figure. Here, in FIGS. 6 to 9, for convenience of explanation, some of the plurality of cropmarks C1 to C4 are not shown. Actually, in FIGS. 6 to 9, the crop marks C1 to C4 are located in the respective rectangular regions 115 as in FIG. 4.

In the present embodiment, of the plurality of rectangular regions 115 and the plurality of images 111, the reference rectangular region 115 and the image 111 are preset. Here, the area 115A1 located in the front right and the image 111 in the area 115A1 are used as a reference, and cutting is started from the image 111 in the area 115A1. However, the reference rectangular region 115 and the image 111 are not limited to the image 111 in the region 115A1 and the region 115A1.

First, in the first step S101 of FIG. 5, the selection unit 81 sets the region 115A1 as a reference for starting cutting to the selection region 125, as shown in FIG. Further, the selection unit 81 sets the crop marks C1 to C4 located at the four corners of the area 115A1 to the selection crop marks SC1 to SC4, respectively. In the present embodiment, the rectangular mark M1 is located in the area 115A1. Therefore, the selection unit 81 sets the rectangular mark M1 located in the area 115A1 to the selection rectangular mark SM1. Information about the selection area 125, the selection crop marks SC1 to SC4, and the selection rectangle mark SM1 is stored in the storage unit 71.

Next, in step S103, the detection unit 83 detects the positions of the selection crop marks SC1 to SC4 and the selection rectangle mark SM1 selected by the selection unit 81 by the sensor 45 (see FIG. 2A). Here, the positions of the selection crop marks SC1 to SC4 and the selection rectangle mark SM1 detected by the sensor 45 are the actual positions with respect to the platen 16. Since the method of detecting the positions of the selection crop marks SC1 to SC4 and the selection rectangle mark SM1 is well known, the specific description thereof will be omitted here. In the present embodiment, the detection unit 83 controls the drive of the feed motor 61 and the scan motor 62, and changes the relative positions of the medium 5 supported by the platen 16 and the sensor 45 provided on the cutting head 40. As a result, the positions of the selection crop marks SC1 to SC4 and the selection rectangle mark SM1 are detected. Information regarding the positions of the selection crop marks SC1 to SC4 detected by the detection unit 83 and the positions of the selection rectangle mark SM1 is stored in the storage unit 71.

As described above, after detecting the positions of the selected crop marks SC1 to SC4 and the selected rectangular mark SM1, in step S105, the correction amount calculation unit 85 performs the selected crop marks SC1 to SC4 and the selected rectangular mark detected by the sensor 45. The correction amount is calculated based on the position of SM1. In the present embodiment, the theoretical positions P11 (see FIG. 3), which are the theoretical positions of the plurality of crop marks C1 to C4 and the plurality of rectangular marks M1 with respect to the platen 16, are preset. This theoretical position P11 is, in other words, the theoretical position of the plurality of crop marks C1 to C4 and the plurality of rectangular marks M1 with respect to the cutting head 40. Here, the "theoretical position" is an appropriate position on the data, the medium 5 is not arranged diagonally with respect to the platen 16, and the left and right ends of the medium 5 are along the sub-scanning direction X. It is the position of a plurality of crop marks C1 to C4 and a plurality of rectangular marks M1 when they are arranged. The theoretical positions P11 of the plurality of crop marks C1 to C4 and the plurality of rectangular marks M1 are stored in the storage unit 71.

The correction amount calculated in step S105 is the correction amount with respect to the theoretical position P11 at each position of the selection crop marks SC1 to SC4 and the selection rectangle mark SM1 detected by the detection unit 83. The correction amount calculated in step S105 is based on the amount calculated when the cutting head 40 is actually positioned at the time of cutting. This correction amount is the first correction amount, which is the correction amount of the main scanning direction Y with respect to the theoretical position P11, and the sub-scanning direction X with respect to the theoretical position P11 at the respective positions of the selected crop marks SC1 to SC4 and the selected rectangular mark SM1. It is calculated based on at least a second correction amount, which is a correction amount. In the present embodiment, this correction amount is calculated by adding so-called trapezoidal correction and rhombus correction in addition to the first correction amount and the second correction amount. The keystone correction and the rhombus correction are corrections for the case where the medium 5 expands and contracts due to temperature and humidity. The specific calculation method of the correction amount can be calculated by a conventional method. Therefore, the description of the specific calculation method of the correction amount will be omitted. The correction amount calculated in step S105 is stored in the storage unit 71.

Next, in step S107, the determination unit 87 determines whether or not the correction amount calculated by the correction amount calculation unit 85 is equal to or less than the allowable correction amount CV1 (see FIG. 3). The permissible correction amount CV1 is a lower limit value of the permissible cutting accuracy, in other words, a value representing the lowest precision that can maintain the quality. In the present embodiment, the larger the value of the correction amount calculated in step S105, the larger the deviation from the theoretical position P11. Therefore, the larger the value of the correction amount, the higher the possibility that the cutting accuracy will be lower. From the above, when the correction amount is larger than the allowable correction amount CV1, it means that the cutting accuracy is not the allowable accuracy. The permissible correction amount CV1 is appropriately set according to the type of the cutting device 100, the type of the medium 5, the deliverable produced by the cutting device 100, and the like. The permissible correction amount CV1 is stored in advance in the storage unit 71.

When the determination unit 87 determines in step S107 that the correction amount is equal to or less than the allowable correction amount CV1, the cutting accuracy can be improved even if the range of the selection area 125 is expanded and the number of images 111 to be cut together is increased. It is determined that it may be possible to keep it. In this case, the process returns to step S101, and the process of resetting the selection area 125, the selection crop marks SC1 to SC4, and the selection rectangle mark SM1 is performed.

In the second and subsequent steps S101, the selection unit 81 sets a new selection area 125 in which a plurality of rectangular areas 115 are combined so that the range is wider than that of the previous selection area 125. In the second and subsequent steps S101, which rectangular region 115 is used as the new selection region 125 is not particularly limited. In this embodiment, a new selection region 125 is set so that at least the reference region 115A1 is included. Here, a new selection area 125 is set so as to extend the range of the selection area 125 to the rectangular area 115 located in the main scanning direction Y rather than the sub scanning direction X.

For example, in the first step S101, as shown in FIG. 6, the area 115A1 is set as the selection area 125. In this case, the regions 115A2 and 115A3 are located in the main scanning direction Y (here, to the left) of the selection region 125. Therefore, in the second step S101, although not shown, the selection unit 81 may set, for example, a region including the regions 115A1 and 115A2 as the new selection region 125.

Further, in the second step S101, as shown in FIG. 7, the selection unit 81 is a region in which the regions 115A1, 115A2, and 115A3 are combined, that is, regions 115A1, 115A2, and 115A3 arranged in the main scanning direction Y of the first row. May be set in the new selection area 125. In this case, the selected crop marks SC1, SC2, SC3, and SC4 are the crop mark C1 of the region 115A1, the crop mark C2 of the region 115A3, the crop mark C3 of the region 115A1, and the crop mark C4 of the region 115A3, respectively. Further, the selected rectangular mark SM1 becomes the rectangular mark M1 in the area 115A1. When a new selection area 125 is set in the second and subsequent steps S101, the previous (first time) selection area 125 (see FIG. 6) is stored as the previous area 135 (see FIG. 7). It is stored in 71. Further, the previous selection crop marks SC1 to SC4 (see FIG. 6) are stored in the storage unit 71 as the previous crop marks PC1 to PC4 (see FIG. 7), and the previous selection rectangular mark SM1 (see FIG. 6) is stored in the storage unit 71. It is stored in the storage unit 71 as a rectangular mark PM1 (see FIG. 7).

Here, as shown in FIG. 7, when the length L1 of the main scanning direction Y of the selection region 125 is the same as the length L2 of the main scanning direction Y of the entire region 116 including all the rectangular regions 115, the selection unit 81 sets a new selection area 125 so as to extend the range of the selection area 125 to the rectangular area 115 located in the sub-scanning direction X. In other words, in the case where the rectangular area 115 does not exist on the Y side of the main scanning direction of the selected area 125 and the selected area 125 is a combination of all the rectangular areas 115 arranged in one line, the selection unit 81 performs the sub-scanning. A new selection area 125 is set so as to extend the range of the selection area 125 to the rectangular area 115 located in the direction X.

For example, in the second step S101, as shown in FIG. 7, it is assumed that a region including regions 115A1, 115A2, and 115A3 arranged in the main scanning direction Y is set as the selection region 125. In this case, the other rectangular region 115 is not located in the main scanning direction Y of the selection region 125. Therefore, in the third step S101, as shown in FIG. 8, the selection unit 81 combines the regions 115A1, 115A2, 115A3 located in the first row and the regions 115B1, 115B2, 115B3 located in the second row. The new area is set to the new selection area 125. In this case, the selected crop marks SC1, SC2, SC3, and SC4 are set as the crop mark C1 in the area 115A1, the crop mark C2 in the area 115A3, the crop mark C3 in the area 115B1, and the crop mark C4 in the area 115B3, respectively. Further, the selection rectangle mark SM1 is set to the rectangle mark M1 in the area 115A1.

In step S107, when the determination unit 87 determines that the correction amount is larger than the allowable correction amount CV1, it is determined that the cutting accuracy is lower than the allowable accuracy when cutting is performed in the selection area 125. In this case, the next step is step S109.

In step S109, the determination unit 89 sets the determination region 145, the determination crop marks DC1 to DC4, and the determination rectangle mark DM1 which are the reference for cutting. For example, in the second step S101, as shown in FIG. 7, a region combining the three regions 115A to 115A3 is set in the selection region 125, and in the third step S101, as shown in FIG. 8, the region is set. It is assumed that a region combining the six regions 115A1 to 115A3 and 115B1 to 115B3 is set as the selection region 125. In this case, in the third step S101, the previous region 135 is a region including the regions 115A1 to 115A3 which are the second selection regions 125. The previous crop marks PC1, PC2, PC3, and PC4 are the second selection crop marks SC1, SC2, SC3, and SC4 (see FIG. 7), respectively, and the crop marks C1 in the area 115A1 and the crop marks C2 in the area 115A3, respectively. The crop mark C3 of 115A1 and the crop mark C4 of the area 115A3. Further, the previous rectangular mark PM1 is the rectangular mark M1 in the area 115A1.

When the determination result becomes NO in the third step S107 and the process proceeds to step S109, the determination unit 89 sets the area including the areas 115A1 to 115A3 which are the previous areas 135 (see FIG. 8) as shown in FIG. Set to the determination area 145. Further, the determination unit 89 uses the determination crop marks DC1, DC2, DC3, and DC4 as the crop marks C1 in the region 115A1 and the crop marks C2 in the region 115A3, which are the previous crop marks PC1, PC2, PC3, and PC4 (see FIG. 8), respectively. , The crop mark C3 in the area 115A1 and the crop mark C4 in the area 115A3 are set. Further, the determination unit 89 sets the rectangle mark M1 of the region 115A1 which is the previous rectangle mark PM1 (see FIG. 8) to the determination rectangle mark DM1.

If the determination result is NO in the first step S107 and the process proceeds to step S109, the previous region 135 and the previous crop marks PC1 to PC4 are not set. In this way, when the previous region 135 and the previous crop marks PC1 to PC4 are not set, cutting may be performed for each rectangular region 115, which is the smallest region. However, in this case, since the correction amount is larger than the allowable correction amount CV1, the cutting accuracy may be lower than the allowable accuracy, and the quality may not be maintained. Therefore, if the determination result is NO in the first step S107, a warning may be notified to the user, for example. This warning notification notifies a warning that the cutting accuracy is low. Here, the warning notification causes the user to select whether or not to start cutting after notifying the above warning. Then, when the user selects to "start cutting", cutting is executed for each rectangular area 115. On the other hand, when the user chooses not to start cutting, an error notification such as an error message is sent. The method of warning notification is not particularly limited, but for example, a warning message and a selection item for whether or not to start cutting may be displayed on the operation panel 55 (see FIG. 1). In this case, the user may select whether or not to start cutting by operating an operation unit (not shown) such as a button on the operation panel 55.

After the determination region 145, the determination crop marks DC1 to DC4 and the determination rectangle mark DM1 are set in step S109, in step S111, the cutting control unit 77 is based on the determination crop marks DC1 to DC4 and the determination rectangle mark DM1. The cutting head 40 is aligned and the medium 5 in the determination region 145 is cut. As a result, the image 111 located in the determination region 145 is cut. Since the positioning of the cutting head 40 here can be performed by a conventional method, detailed description thereof will be omitted.

In the present embodiment, the cutting control unit 77 divides the area of the printed image 110 other than the determination area 145 into a plurality of division areas 155 so as to be an area having the same size as the determination area 145. Then, the cutting control unit 77 cuts the medium 5 for each division region 155. As shown in FIG. 9, for example, in the case of the regions 115A1, 115A2, 115A3 in which the determination region 145 is arranged in the main scanning direction Y of the first row, the region 115B1 is arranged as the division region 155 in the main scanning direction Y of the second row. , 115B2, 115B3 are combined, and the first division area 155A is divided into a second division area 155B, which is a combination of regions 115C1, 115C2, and 115C3 arranged in the main scanning direction Y of the third row. .. The determination region 145, the first division region 155A, and the second division region 155B are regions arranged in the sub-scanning direction X.

The cutting control unit 77 aligns the cutting head 40 based on the determination crop marks DC1 to DC4 and the determination rectangle mark DM1 located at the four corners of the determination region 145. Then, the cutting control unit 77 cuts the medium 5 along the cut line 113 in the determination region 145. Next, the cutting control unit 77 cuts the medium 5 in the first partition region 155A. In this case, the crop mark C1 of the region 115B1, the crop mark C2 of the region 115B3, the crop mark C3 of the region 115B1, the crop mark C4 of the region 115B3, and the crop mark C4 of the region 115B1, which are crop marks located at the four corners of the first division region 155A. The cutting head 40 is positioned based on the rectangular mark M1 of the above. After that, the cutting control unit 77 cuts the medium 5 along the cut line 113 in the first division region 155A. Next, the cutting control unit 77 cuts the medium 5 in the second division region 155B. In this case, the crop mark C1 of the region 115C1, the crop mark C2 of the region 115C3, the crop mark C3 of the region 115C1, the crop mark C4 of the region 115C3, and the crop mark C1 of the region 115C1 which are the crop marks located at the four corners of the second division region 155B The cutting head 40 is positioned based on the rectangular mark M1 of the above. After that, the cutting control unit 77 cuts the medium 5 along the cut line 113 in the second division region 155B. As described above, the printed image 110 printed on the medium 5 can be cut.

As described above, in the present embodiment, the correction amount calculated by the correction amount calculation unit 85 is based on the actual position of the selection crop marks SC1 to SC4 (see, for example, FIG. 6) detected by the sensor 45 (see FIG. 2A). Since it is calculated, it can be said that it is an accurate value. The range to be cut at one time is determined based on this correction amount. For example, when the correction amount is equal to or less than the allowable correction amount CV1 (see FIG. 3), the selection area 125 is set again so as to widen the cutting range. On the other hand, when the correction amount is larger than the allowable correction amount CV1, the cutting accuracy is lowered, so that the cutting is performed in the range corresponding to the previous crop marks PC1 to PC4 which are the previously selected crop marks SC1 to SC4. Therefore, the cutting time can be shortened within the range of acceptable cutting accuracy. Therefore, it is possible to achieve both a reduction in cutting time and an improvement in cutting accuracy in a well-balanced manner.

In the present embodiment, when a new selection area 125 is set by the selection unit 81, as shown in FIGS. 6 and 7, the selection area 125 is moved to the rectangular area 115 located in the main scanning direction Y rather than the sub scanning direction X. A new selection area 125 is set to expand the range of. For example, in the first step S101, as shown in FIG. 6, the area 115A1 is set as the selection area 125. In this case, the regions 115A2 and 115A3 are located in the main scanning direction Y (here, to the right) of the selection region 125. Therefore, in the second step S101, for example, the selection unit 81 sets a region including the regions 115A1, 115A2, and 115A3 in the selection region 125, as shown in FIG. 7. In the present embodiment, since the medium 5 is conveyed in the sub-scanning direction X, if the length of the sub-scanning direction X of the selection region 125 is increased, it is easily affected by the misalignment of the medium 5 with respect to the platen 16, and the cutting accuracy. Is likely to be low. Therefore, when setting a new selection area 125, the range of the selection area 125 is expanded to the rectangular area 115 located in the main scanning direction Y rather than the sub-scanning direction X, so that the cutting accuracy is maintained. It is easy to expand the range of the selection area 125.

In the present embodiment, as shown in FIG. 7, when the length L1 of the main scanning direction Y of the selected region 125 is the same as the length L2 of the main scanning direction Y of the entire region 116 including all the rectangular regions 115, The selection unit 81 sets a new selection area 125 so as to extend the range of the selection area 125 to the rectangular area 115 located in the sub-scanning direction X. For example, in the second step S101, as shown in FIG. 7, it is assumed that a region including regions 115A1, 115A2, and 115A3 arranged in the main scanning direction Y is set as the selection region 125. In this case, the other rectangular region 115 is not located in the main scanning direction Y of the selection region 125. Therefore, in the third step S101, as shown in FIG. 8, the selection unit 81 combines the regions 115A1, 115A2, 115A3 located in the first row and the regions 115B1, 115B2, 115B3 located in the second row. The new area is set to the new selection area 125. This makes it possible to expand the selection area 125 in the sub-scanning direction X while maintaining the cutting accuracy. Therefore, it is possible to further shorten the cutting time while maintaining the cutting accuracy.

In the present embodiment, as shown in FIG. 9, the cutting control unit 77 divides the area of the printed image 110 other than the determination area 145 into a plurality of division areas 155 so as to be an area having the same size as the determination area 145. Then, the medium 5 is cut for each division region 155. Here, since the size of the determination region 145 and the size of the division region 155 are the same, the accuracy of cutting in the determination region 145 and the accuracy of cutting in the division region 155 are substantially the same. Therefore, by setting the division area 155 having the same size as the determination area 145, the processing of steps S101 to S107 in FIG. 5 can be omitted when setting the division area 155. Therefore, the processing time can be shortened.

In the present embodiment, for example, the division region 155 has a first division region 155A and a second division region 155B located side by side in the sub-scanning direction X. The determination region 145, the first division region 155A, and the second division region 155B are located side by side in the sub-scanning direction X. As a result, when cutting the determination region 145, the first division region 155A, and the second division region 155B, the same processing is likely to be performed. Therefore, the complexity of control can be suppressed.

In the present embodiment, the correction amount calculation unit 85 determines the first correction amount in the main scanning direction Y with respect to the theoretical position P11 (see FIG. 3) at the positions of the selection crop marks SC1 to SC4 detected by the detection unit 83, and the theory. The correction amount is calculated at least based on the second correction amount in the sub-scanning direction X with respect to the position P11. In the present embodiment, as a factor of lowering the cutting accuracy, it is considered that the medium 5 is obliquely displaced with respect to the platen 16 when the medium 5 is conveyed. When the medium 5 is obliquely displaced, the medium 5 is displaced with respect to both the main scanning direction Y and the sub-scanning direction X. Therefore, by calculating the correction amount based on the first correction amount and the second correction amount as described above, it is possible to calculate the correction amount in consideration of the oblique deviation of the medium 5.

The cutting device 100 according to the present embodiment includes a print head 30, and is a device capable of printing and cutting on the medium 5. The image print control unit 73 prints the print image 110 on the medium 5 supported by the platen 16. The crop mark printing control unit 75 prints a plurality of crop marks C1 to C4 on the medium 5 supported by the platen 16. As a result, the printing image 110 can be printed on the medium 5 and the medium 5 can be cut by one cutting device 100. For example, when the cutting device is not provided with the printing function, the operator needs to set the medium 5 on which the printed image 110 is printed on the platen of the cutting device. At this time, the position may be displaced with respect to the platen. However, in the present embodiment, the work of setting the medium 5 on the platen 16 after printing does not occur. Therefore, the risk of misalignment of the medium 5 with respect to the platen 16 can be reduced.

In the above embodiment, the cutting device 100 has a printing function and includes a printing head 30. However, the print head 30 may be omitted, and the cutting device 100 may not have a printing function. In this case, the print image 110 and the plurality of crop marks C1 to C4 are printed on the medium 5 by another printer. Then, when the user sets the printed medium 5 on the platen 16, the medium 5 is cut.

In the above embodiment, as shown in FIG. 2A, the printing head 30 and the cutting head 40 are connected by connecting members 34 and 44 composed of magnets. For example, at the time of cutting, only the cutting head 40 was moved in the main scanning direction Y in a state where the printing head 30 and the cutting head 40 were disconnected by the connecting members 34 and 44. For example, at the time of printing, the print head 30 was moved in the main scanning direction Y together with the cutting head 40 in a state where the print head 30 and the cutting head 40 were connected. However, the configuration for moving the print head 30 and the cutting head 40 in the main scanning direction Y is not particularly limited. For example, a connecting carriage engaged with the guide rail 18 may be provided between the printing head 30 and the cutting head 40. The connecting carriage is configured to move along the guide rail 18 in the main scanning direction Y, and is configured so that the print head 30 and the cutting head 40 can be selectively connected. In this case, for example, at the time of cutting, the cutting head 40 moves in the main scanning direction Y together with the connecting carriage with the cutting head 40 connected to the connecting carriage. For example, at the time of printing, the print head 30 moves in the main scanning direction Y together with the connected carriage in a state where the print head 30 is connected to the connected carriage.
