(Media printing method, cutting method)
FIG. 10 is a block diagram for explaining the configuration of the cutting device 1 shown in FIG. 1. As shown in FIG.

In the cutting device 1 of the present embodiment, when the medium 2 is printed by the printing mechanism 3, the medium 2 is cut by the cutting mechanism 7 and the second cutting mechanism 8, and the part to be cut 2a is cut off. In this embodiment, the medium 2 that has passed through the after-platen 25 after printing moves toward the tension bar 9 as indicated by the solid line in FIG. When the part to be cut 2a is cut, the second medium transport mechanism 30 transports the medium 2 on the cutting platen 31, so that the second cutting mechanism 8 forms cut lines CL11 to CL14 along the medium transport direction on the medium 2. do. Further, by moving the carriage 34 in the left-right direction while the medium 2 on the cutting platen 31 is stopped, the cutting mechanism 7 forms a cut line CL1 parallel to the medium width direction (left-right direction).

If the cutting position in the medium transport direction (that is, the position where the cut line CL1 is formed in the medium transport direction) of the medium 2 that is linearly cut in the horizontal direction by the cutting mechanism 7 after printing is defined as the medium cutting position, then the printing mechanism As shown in FIG. 2, 3 prints an image on the medium 2 and prints on the medium 2 a cut position mark (register mark) M1 for specifying the medium cut position. The printing mechanism 3 prints a cut position mark M1 on one end of the medium 2 in the horizontal direction.

The cut position mark M1 is a straight line (line segment) parallel to the left-right direction, and is printed on the portion of the medium 2 that will become the second margin 2c. Also, the cut position mark M1 is printed at a position a fixed distance away from the medium cut position downstream in the transport direction. That is, the printing mechanism 3 prints a plurality of cut position marks M1 at positions separated from each of the plurality of medium cut positions by a certain distance downstream in the transport direction. A plurality of cut position marks M1 are printed at the same position in the horizontal direction.

In addition, the cutting range in the medium width direction (horizontal direction) of the medium 2 at the medium cutting position (that is, the range in which the cutting line CL1 is formed in the horizontal direction) is defined as the medium cutting range, and the medium is cut by the second cutting mechanism 8 after printing. If the cut position in the left-right direction (that is, the position where the cut lines CL11 to CL14 are formed in the left-right direction) of the medium 2 that is cut linearly in the conveying direction of the medium 2 is defined as a second medium cut position, then the cutting device 1 In an electrically connected personal computer (PC) 61, image data, which is data of an image to be printed on the medium 2 (specifically, an image to be printed on the portion to be cut 2a), and the medium cut position are specified. mark printing data for printing the cut position mark M1; cut range data for specifying the medium cut range; and the second medium cut. Second cut position data, which is data for specifying the position, is created.

In this embodiment, the cutting device 1 and the PC 61 constitute a printing system. When these data are created in the PC 61, the operator can adjust the position of the second cutting mechanism 8 in the horizontal direction while confirming the second medium cutting position displayed on the display of the PC 61, for example. A second cutting mechanism 8 is fixed to the frame 35 .

When the operator performs a predetermined operation on the PC 61 , the PC 61 transmits the created image data, cut position data, mark printing data and cut range data to the print control section 62 which is the control section of the printing mechanism 3 . Then, the print control unit 62 receives these data. That is, the printing mechanism 3 receives these data. The mark printing data includes mark position data for specifying the position of the cut position mark M1 in the horizontal direction.

The print control unit 62 receives the image data, the cut position data, the mark printing data, and the cut range data. Data and mark position data are corrected, and the corrected cut position data, cut range data, and mark position data are sent to the cutting control section 63, which is the control section of the cutting mechanism 7, and the cutting control section 63 transmits these data. receive. That is, the cutting mechanism 7 receives these data.

After receiving the cut position data, the cut range data, and the mark position data, the cutting control unit 63 moves the carriage 34 to a position where the sensor 56 can detect the cut position mark M1 based on the mark position data. That is, the carriage drive mechanism 36 moves the carriage 34 to a position where the sensor 56 can detect the cut position mark M1 based on the mark position data. When the cutting mechanism 7 cuts the medium 2, this position becomes the reference position of the carriage 34, and the carriage 34 starts to move from this position. In this state, the printing mechanism 3 prints an image on the medium 2 based on the image data, and prints the cut position mark M1 on the medium 2 based on the mark printing data.

Also, the cutting mechanism 7 cuts the medium 2 based on the cut range data. When the cutting mechanism 7 cuts the medium 2, the medium 2 on the cutting platen 31 is stopped. The stop position of the medium 2 is controlled based on the detection result of the sensor 56 and cutting position data. Specifically, after the sensor 56 detects the cut position mark M1, when the medium 2 is conveyed by a predetermined amount by the second medium conveying mechanism 30, the medium 2 stops and the cutting mechanism 7 cuts the medium 2. do.

In this embodiment, if the light shielding portion 53a of the light shielding member 53 shields the light emitting portion and the light receiving portion of the first sensor 48 and the light shielding portion 53b shields the light emitting portion and the light receiving portion of the second sensor 49, , the carriage 34 can be moved in the horizontal direction. That is, when the cutting mechanism 7 forms the cut line CL1, the light blocking portion 53a blocks the space between the light emitting portion and the light receiving portion of the first sensor 48, and the light blocking portion 53b blocks the light emitting portion and the light receiving portion of the second sensor 49. A tension bar 9 is arranged at a position that blocks the gap between the Further, in this embodiment, even if the tension bar 9 moves in a predetermined range in the front-rear direction, the light blocking portion 53a blocks the space between the light emitting portion and the light receiving portion of the first sensor 48, and the light blocking portion 53b blocks the second sensor 49. The state of blocking the space between the light emitting portion and the light receiving portion is maintained.

It is possible to appropriately cut the medium 2 by the cutting mechanism 7 by preventing interference with the widthwise end of the medium 1 .

Further, in this embodiment, since the portion to be cut 2a and the first blank portion 2b are guided to the lower front side by the guide member 29 arranged below the cutting mechanism 7, the width direction of the first medium portion is reduced. In this embodiment, the lower end of the inclined surface forming portion 44g of the medium pressing member 44 moves upward toward the first direction. It becomes 44 h of inclined surfaces which incline.

A line CL2 is formed. When the medium 2 is half-cut, the medium 2 is transported to both sides in the medium transport direction, that is, the transport of the medium 2 to the downstream side in the transport direction and the transport of the medium 2 to the upstream side in the transport direction.

If the medium 2 is sandwiched between the transport roller 32 and the pad roller 33 in the stopped state, the medium transport mechanism 5 cannot transport the medium 2 upstream in the transport direction by a predetermined amount or more. Further, even if it were possible to retract the pad roller 33 and create a situation in which the medium 2 was not sandwiched between the transport roller 32 and the pad roller 33, the medium transport direction When the medium 2 is cut by the cutting mechanism 7 and the second cutting mechanism 8 in a situation where the medium 2 is conveyed to both sides of the medium width direction and the medium conveyance direction There is a possibility that the medium 2 may not be cut properly.

In addition, the medium 2 that has been wound into a roll after being printed and half-cut is fed again from the medium feeding unit 14 and cut by the cutting mechanism 7 and the second cutting mechanism 8 . That is, if the medium 2 after being printed by the printing mechanism 3 and removed from the medium take-up unit 17 is the medium after printing, then the medium after printing wound in a roll is the medium after printing. It is attached to the extraction part 14 . Further, the cutting mechanism 7 and the second cutting mechanism 8 cut the medium after printing.

In this embodiment, the downstream end in the transport direction of the medium 2 when printing and half-cutting is performed is the upstream end in the transporting direction of the medium 2 when cutting is performed by the cutting mechanism 7 and the second cutting mechanism 8. The upstream end in the transport direction of the medium 2 during cutting is the downstream end in the transport direction of the medium 2 during cutting by the cutting mechanism 7 and the second cutting mechanism 8 . The right edge of the medium 2 when printing and half-cutting is the left edge of the medium 2 when it is cut by the cutting mechanism 7 and the second cutting mechanism 8, and the left edge of the medium 2 when printing and half-cutting is , the right edge of the medium 2 when cutting is performed by the cutting mechanism 7 and the second cutting mechanism 8 .

The sensor 67 is a reflective optical sensor similar to the sensor 56 , and includes a light-emitting portion and a light-receiving portion that receives light emitted from the light-emitting portion and reflected by the medium 2 . The light emitting portion of the sensor 67 emits light downward. The sensor 67 is electrically connected to the print control section 62 .

As in Embodiment 1, if the cutting range in the left-right direction of the medium 2 at the medium-cutting position (that is, the range in which the cutting line CL1 is formed in the left-right direction) is defined as the medium cutting range, the printing mechanism 3 of the present embodiment , an image and a cutting position mark M1 are printed on the medium 2, and a first cutting range mark M11 is arranged at a position corresponding to one end of the medium cutting range in the horizontal direction, and the other end of the medium cutting range in the horizontal direction. , and an origin specifying mark M2 for specifying the origin are printed on the medium 2 .

As in the first embodiment, the cut position mark M1 is a straight line (segment) parallel to the left-right direction, and the printing mechanism 3 cuts at one end in the left-right direction of the medium 2 that becomes the second margin 2c. A position mark M1 is printed. In addition, the cut position mark M1 of the present embodiment is printed at a position separated from the medium cut position by a certain distance upstream in the transport direction (see FIG. 11A). That is, the printing mechanism 3 prints a plurality of cut position marks M1 at positions separated by a certain distance upstream in the transport direction from each of the plurality of medium cut positions.

The first cut range mark M11 and the second cut range mark M12 are straight lines (line segments) parallel to the medium transport direction. The printing mechanism 3 prints the first cut range mark M11 and the second cut range mark M12 on the upstream end in the transport direction of the medium 2 wound by the medium winding unit 17 . For example, as shown in FIG. 11, when two cut portions 2a are arranged side by side in the width direction of the medium 2, the printing mechanism 3 sets the two first cut range marks M11 and 2 A mark M12 for the second cut range of the book is printed.

In this embodiment, the printing mechanism 3 prints the first cutting range mark M11 inside the left-right direction from one end of the medium cutting range in the left-right direction, and prints the first cutting range mark M11 inside the left-right direction from the other end of the medium cutting range in the left-right direction. A second cut range mark M12 is printed on the inner side. Further, as in the first embodiment, the cutting position in the left-right direction (that is, the cut lines CL11 to CL14 are formed in the left-right direction) of the medium 2 that is linearly cut in the medium conveying direction by the second cutting mechanism 8. position) is the second medium cut position, the printing mechanism 3 prints the first cut range mark M11 and the second cut range mark M12 at the same position as the second medium cut position in the horizontal direction.

Note that the printing mechanism 3 prints the first cut range mark M11 and the second cut range mark M12 printed on the upstream end in the transport direction of the medium 2 wound by the medium winding unit 17. In addition, the first cut range mark M11 and the second cut range mark M12 may be printed in the first margin 2b at a predetermined pitch in the medium transport direction.

The origin specifying mark M2 is a straight line (line segment) parallel to the medium transport direction. The printing mechanism 3 prints the origin mark M<b>2 on the upstream end in the transport direction of the medium 2 wound by the medium winding unit 17 . Further, for example, the downstream end in the transport direction of the origin specifying mark M2 is connected to the inner end in the left-right direction of the cut position mark M1 that is printed furthest upstream in the transport direction. 2 Printed on one end in the left-right direction of the medium 2, which serves as the margin 2c.

In this embodiment, before the printing and half-cutting of the medium 2 are performed, the PC 61 stores image data, which is data of an image to be printed on the medium 2 (specifically, an image to be printed on the portion to be cut 2a). , half-cut data for half-cutting the medium 2, cut position data for specifying the medium cut position, and data for printing the cut position mark M1 on the medium 2. First mark printing data, cut range data for specifying a medium cut range, and second cut position data for specifying a second medium cut position are created. In addition, before the medium 2 is printed and half-cut, the PC 61 performs the second mark printing data for printing the first cut range mark M11 and the second cut range mark M12 on the medium 2. Data and third mark printing data for printing the origin specifying mark M2 on the medium 2 are created.

For example, the operator of the cutting device 1 creates these data on the display of the PC 61. FIG. After these data are created in the PC 61, when the operator performs a predetermined operation on the PC 61, the PC 61 stores the created image data, half-cut data, cut position data, first mark printing data, second mark The print data, the third mark print data, and the cut range data are sent to the print control unit 62, and the print control unit 62 receives these data. That is, the printing mechanism 3 receives these data.

The printing mechanism 3 that has received the data prints an image on the medium 2 based on the image data, prints a plurality of cut position marks M1 on the medium 2 based on the data for printing the first marks, and prints the marks M1 for printing the second marks. The first cut range mark M11 and the second cut range mark M12 are printed based on the data, and the origin specifying mark M2 is printed based on the third mark print data. Further, the printing mechanism 3 half-cuts the medium 2 based on the half-cutting data after printing the medium 2 . As described above, when the medium 2 is printed and half-cut, the medium 2 that has passed through the after-platen 25 after printing and half-cutting passes through the front side of the cutting mechanism 7, the second cutting mechanism 8, and the tensioning mechanism 10, and the cutting mechanism. The medium 2 is set so as to be wound up by the medium winding mechanism 26 after passing under the medium 7 .

After being printed and half-cut, the medium 2 is wound into a roll by the medium winding mechanism 26 and removed from the medium winding section 17 by the operator. The roll-shaped medium 2 after printing and half-cutting removed from the medium winding section 17 is attached to the medium feeding section 14 by the operator. The roll-shaped medium 2 attached to the medium delivery unit 14 is pulled out by the operator, and the downstream end of the medium 2 in the transport direction is placed on the print platen 24 .

After that, the sensor 67 detects the origin specifying mark M2, and also detects the cut position mark M1 (that is, the cut position mark printed on the most downstream side in the transport direction) to which the upstream end of the origin specifying mark M2 is connected. M1) is detected. The print control unit 62 identifies the origin position based on the detection result of the sensor 67 . In this embodiment, for example, the origin position of the medium 2 is the position of the connection point between the origin specifying mark M2 and the cut position mark M1. After that, the sensor 67 detects the first cut range mark M11 and the second cut range mark M12.

When the sensor 67 detects the origin specifying mark M2, the first cut range mark M11, and the second cut range mark M12, the carriage 21 moves in the horizontal direction. Further, when the sensor 67 detects the cut position mark M1, the medium transport mechanism 5 transports the medium 2. As shown in FIG. Before the sensor 67 detects the origin specifying mark M2 and the cutting position mark M1, the position of the carriage 21 in the left-right direction and the downstream end of the medium 2 in the medium-conveying direction are position is adjusted by the operator. Specifically, the carriage 21 is equipped with a laser pointer that emits a laser beam downward. and the position of the downstream end of the medium 2 in the transport direction.

Based on the detection result of the cut position mark M1 by the sensor 67, the print control unit 62 generates mark position data, which is data for specifying the position of the cut position mark M1 in the left-right direction. The cut range data is corrected based on the detection result of the first cut range mark M11 and the second cut range mark M12 in , and the corrected cut range data is generated. The print control unit 62 also transmits the cut position data, the mark position data, and the corrected cut range data to the cut control unit 63, and the cut control unit 63 receives these data. That is, the cutting mechanism 7 receives these data.

After receiving the cut position data, the cut range data, and the mark position data, the cutting control unit 63 moves the carriage 34 to a position where the sensor 56 can detect the cut position mark M1 based on the mark position data. That is, the carriage drive mechanism 36 moves the carriage 34 to a position where the sensor 56 can detect the cut position mark M1 based on the mark position data received by the cutting mechanism 7 . When the cutting mechanism 7 cuts the medium 2, this position becomes the reference position of the carriage 34, and the carriage 34 starts to move from this position.

In addition, the operator uses, for example, the first cutting range mark M11 and the second cutting range mark M12 printed at the same position as the second medium cutting position in the horizontal direction as a guide, and moves the second cutting mechanism 8 in the horizontal direction. position is adjusted to fix the second cutting mechanism 8 to the support frame 35 . Thereafter, the cutting of the medium 2 by the second cutting mechanism 8 and the cutting of the medium 2 by the cutting mechanism 7 are performed.

As in the first embodiment, the medium 2 is cut by the second cutting mechanism 8 as the medium 2 is conveyed by the second medium conveying mechanism 30 . A cutting mechanism 7 cuts the medium 2 based on the cut range data. When the cutting mechanism 7 cuts the medium 2, the medium 2 on the cutting platen 31 is stopped. As in the first embodiment, the stop position of the medium 2 is also controlled based on the detection result of the sensor 56 and cut position data in this embodiment. Specifically, after the sensor 56 detects the cut position mark M1, when the medium 2 is conveyed by a predetermined amount by the second medium conveying mechanism 30, the medium 2 stops and the cutting mechanism 7 cuts the medium 2. do. When the medium 2 is cut by the cutting mechanism 7, the cut position mark M1 is arranged at a certain distance downstream in the transport direction from the medium cut position (see FIG. 11B).

As described above, in the present embodiment, the cutting mechanism 7 uses the cut range data (that is, the cutting mechanism 7 cuts the medium 2 in the horizontal direction based on the cut range data received from the print control unit 62 and the detection result of the sensor 56 . That is, the cutting mechanism 7 cuts the medium 2 horizontally based on the detection results of the sensors 56 and 67 .

When the first cut range mark M11 and the second cut range mark M12 are printed in the first margin 2b, the cutting of the medium 2 by the cutting mechanism 7 and the second cutting mechanism 8 is started. Later, the sensor 67 may again detect the origin specifying mark M2, the cutting position mark M1, the first cutting range mark M11, and the second cutting range mark M12. In this case, the print control unit 62 generates mark position data again, corrects the cut range data, and transmits the cut position data, the mark position data, and the corrected cut range data to the cut control unit 63. do.

In the second embodiment, instead of half-cutting the medium 2, perforations having a predetermined shape corresponding to the image printed on the medium 2 may be formed on the medium 2 after printing. In this case, for example, medium 2 is made of paper, and cutting head 66 forms perforations in medium 2 after printing. Also, in this case, for example, a perforation cut line having the same shape as the half cut line CL2 is formed on the medium 2 . Further, in the second embodiment, instead of half-cutting the medium 2, the medium 2 may be cut out for decoration by cutting out part of the medium 2 after printing. Furthermore, in the second embodiment, instead of half-cutting the medium 2, forming perforations in the medium 2, or cutting out the medium 2, predetermined processing may be performed on the medium 2. FIG. Even in this case, the medium 2 is transported to both sides in the medium transport direction when a predetermined process is performed on the medium 2 .
