Then, the CPU 201 sends a transmission command of the image data to the left camera 210L (FIG. 14: Step S112), and if the image data is sent from the left camera 210L in response to the transmission command (YES in step S113), the memory M5 is used. The count value Y is set to 1 (step S114), the count value X in the memory M6 is set to 1 (step S115), and the image data from the left camera 210L at the pixel position specified by the count values X and Y is written.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (Yes in step S119), the count value Y in the memory M5 is incremented by 1 (step S120), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S121) repeats the processing operations of steps S115 to S122 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S122.

Thereby, in the memory M7, the image data of the a×b pixel from the left camera 210L of the first mark position PM1 is memorized. Here, as shown in FIG. 66A, the image data of the first registration mark RM1 _L1 including the printed matter 4A is stored in the memory M7 as image data of a × b pixels.

Furthermore, in the memory M16, as shown in FIG. 66A, the first registration standard The pixel data of c × d of RM1 is recorded and stored as pattern matching data. Further, the vertical direction of the camera is the same as the vertical direction of the to-be-printed object 4A, and the left-right direction of the camera is the same direction as the left-right direction of the to-be-printed object 4A.

Next, the CPU 201 sends a transmission command of the image data to the right camera 210R (FIG. 15: Step S123), and if the image data is sent from the right camera 210R in response to the transmission command (YES in step S124), the memory M5 is used. The count value Y is set to 1 (step S125), the count value X in the memory M6 is set to 1 (step S126), and the image data from the right camera 210R at the pixel position specified by the count values X and Y is written.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (YES in step S130), the count value Y in the memory M5 is incremented by one (step S131), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S132) repeats the processing operations of steps S126 to S133 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S133.

Thereby, in the memory M11, the image data of the a×b pixel from the right camera 210R of the first mark position PM1 is memorized. Here, as shown in FIG. 67A, the image data of the first registration mark RM1 _R1 including the to-be-printed object 4A is stored in the memory M11 as image data of the a×b pixel.

Next, the CPU 201 loads the rotational speed Vc of the camera moving motor from the memory M1 (FIG. 16: Step S134), and passes the reverse rotation command and the rotational speed Vc of the camera moving motor to the camera moving motor driver 212 via D/. The A converter 215 outputs (step S135). Thereby, the camera movement motor 211 is reversed at the rotation speed Vc, and the left camera 210L and the right camera 210R stopped at the first mark position PM1 in FIG. 1 (FIG. 2), and simultaneously moved to the printing table 3 to the right.

The CPU 201 loads the count value of the camera position detecting counter 214 during the movement of the left camera 210L and the right camera 210R (step S136), and calculates the left camera 210L and the right camera 210R from the count value of the camera position detecting counter 214.

When the CPU 201 confirms that the current position PCM _{R of the} left camera 210L and the right camera 210R has reached the second mark position PM2 (YES in step S139), the CPU 201 outputs an imaging command to the left camera 210L and the right camera 210R (step S140), and takes a picture with the left camera 210L. The area including the first registration mark RM1 _L2 on the printed matter 4A is photographed by the right camera 210R, and the area including the first registration mark RM1 _R2 on the printed matter 4A is imaged.

Then, the CPU 201 sends a transmission command of the imaging data to the left camera 210L (step S141), and if the imaging data is sent from the left camera 210L in response to the transmission command (YES in step S142), the count value Y in the memory M5 is obtained. Set to 1 (step S143), set the count value X in the memory M6 to 1 (FIG. 17, step S144), the image data from the left camera 210L at the pixel position specified by the count values X and Y is written in the address position of (X, Y) of the memory M12 (step S145). .

Then, the CU 201 adds 1 to the count value X in the memory M6 (step S146), loads the number of pixels a in the left-right direction of the camera in the memory M8 (step S147), and repeats the processing operations of steps S145 to S148 until In step S148, the count value X exceeds the pixel value a in the left and right direction of the camera.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (YES in step S148), the count value Y in the memory M5 is incremented by 1 (step S149), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S150) repeats the processing operations of steps S144 to S151 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S151.

Thereby, in the memory M12, the image data of the a×b pixel from the left camera 210L at the second mark position PM2 is memorized. Here, as shown in FIG. 68A, the image data of the first registration mark RM1 _L2 including the printed matter 4A is stored in the memory M12 as image data of the a×b pixel.

Next, the CPU 201 sends a transmission command of the image data to the right camera 210R (step S152), and if the image data is sent from the right camera 210R in response to the transmission command (YES in step S153), the count value Y in the memory M5 is obtained. 1 (FIG. 18: Step S154), the count value X in the memory M6 is set to 1 (step S155), and the image data from the right camera 210R at the pixel position specified by the count values X and Y is written.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (YES in step S159), the count value Y in the memory M5 is incremented by 1 (step S160), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S161) repeats the processing operations of steps S155 to S162 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S162.

Thereby, in the memory M13, the image data of the a×b pixel from the right camera 210R of the second mark position PM2 is memorized. Here, as shown in FIG. 69A, the image data of the first registration mark RM1 _R2 including the printed matter 4A is stored in the memory M13 as image data of a × b pixels.

Then, the CPU 201 continues the movement of the left camera 210L and the right camera 210R, and if the origin position detector 216 of the camera detects that the left camera 210L and the right camera 210R have returned to the origin position (initial position) (step S163, YES) The camera movement motor driver 212 sends a stop command (step S164) to stop the movement of the left camera 210L and the right camera 210R.

[Detecting the position of the first registration mark by pattern matching]

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 19: step S165), sets the count value X in the memory M6 to 1 (step S166), and sets the count value N in the memory M14. 1 (step S167), the memory M15 The count value M in the middle is set to 1 (step S168).

Then, the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M7 is loaded (step S169), and the (M, N) in the memory M16 is loaded. The pixel data of the first registration mark of the address position (step S170), confirming the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the loaded memory M7 Whether or not the pixel data of the address position of (M, N) in the memory M16 coincides (step S171, refer to FIG. 66A).

Here, since the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M7 and the address position of (M, N) in the memory M16 are The pixel data of the first registration mark is inconsistent (step S169, No), from the address of the (X, Y) address at the time to the address of the left camera 210L of the address of (X+c-1, Y+d-1) Any of the image data of the image data at the mark position is different from the pixel data of the first registration mark, and the range from the address of (X, Y) is the left first registration mark RM1 of the first mark position PM1. _L1 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 20: Step S172), and loads the number of pixels a in the left-right direction of the camera in the memory M8 and the first registration mark in the memory M17. The number of pixels c in the left-right direction (steps S173 and S174) is repeated until the processing of steps S167 to S175 is performed until the count value X exceeds "a-c+1" in step S175.

In this processing operation, if the count value X exceeds "a-c+1" (YES in step S175), the left-right direction end of the image data of the first mark position of the left camera 210L is exceeded, so the CPU 201 pairs the memory M5. The count value Y in the middle is incremented by 1 (step S176), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the image in the vertical direction of the first registration mark in the memory M18 The prime number d (steps S177 and S178) repeats the processing operations of steps S166 to S179 until the count value Y exceeds "b-d+1" in step S179.

In this processing operation, the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M7 and the bit of (M, N) in the memory M16 are confirmed. The pixel data of the first registration mark of the address position coincides (FIG. 19: YES in step S171), and the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 21: step S181), and loads the first from the memory M17. The number of pixels c in the left-right direction of one set of marks is set (step S182), and the processing operations of steps S169 to S183 are repeated until the count value M exceeds the number of pixels c in the left-right direction of the first registration mark in step S183.

When the count value M exceeds the number of pixels c in the left-right direction of the first registration mark (YES in step S183), the CPU 201 adds 1 to the count value N in the memory M14 (step S184), and loads the first set from the memory M18. The number of pixels d in the vertical direction of the quasi mark (step S185), the processing operations of steps S168 to S186 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first registration mark in step S186.

In this manner, the CPU 201 performs pattern matching on the pixel data of the first registration mark of c×d in the memory M16 for the image data of the a×b pixel in the memory M7 (the image data of the left first mark position). The count value N exceeds the number d of pixels in the vertical direction of the first registration mark (YES in step S186), and the (X, Y) address of the image data of the a×b pixel in the memory M7 is determined to (X+c). The range of the address of -1, Y+d-1) includes the pixel data of the first registration mark of c × d in the memory M16. That is, it is determined that the first registration mark RM1 (RM1 _L1 ) is included in the image of the first mark position PM1 captured by the left camera 210L.

In the case where the count value Y exceeds "b-d+1" (YES in step S179), the upper and lower ends of the image data of the first mark position of the left camera 210L are exceeded, and the CPU 201 determines that the camera is left. The image of the first mark position PM1 taken at 210L does not include the first registration mark RM1 (RM1 _L1 ), and the display 205 is erroneously displayed (step S180).

When the CPU 201 determines that the first registration mark RM1 _{L1 is} included in the image of the first mark position PM1 captured by the left camera 210L (YES in step S186), the CPU 201 loads the count value X in the memory M6 at that time (step S187). From the count value X loaded, the measurement position M1x1 _L in the X direction of the first registration mark RM1 _L1 is calculated and written in the address position in the X direction in the memory M19 (step S188). Further, the count value Y in the memory M5 at the time is loaded (step S189), and the measurement position M1y1 _L in the Y direction of the first registration mark RM1 _L1 is calculated from the loaded count value Y, and written in the memory. The address position of the Y direction in M19 (step S190, refer to FIG. 66B).

Further, the measurement position M1x1 _L in the X direction of the registration mark RM1 _L1 is obtained from the position in the left-right direction in which the left camera 210L is provided and the count value X, and the measurement position M1y1 _{L in the} Y direction is from the first mark position PM1. And the count value Y is obtained.

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 22: step S191), sets the count value X in the memory M6 to 1 (step S192), and sets the count value N in the memory M14. If it is 1 (step S193), the count value M in the memory M15 is set to 1 (step S194).

Then, the bit of (X+M-1, Y+N-1) in the memory M12 is loaded. The pixel data of the left camera at the address position (step S195), the pixel data of the first registration mark of the address position of (M, N) in the memory M16 is loaded (step S196), and the loaded memory is confirmed. Whether the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in M12 coincides with the pixel data of the address position of (M, N) in the memory M16 (step S197) , refer to Figure 68A).

Here, the pixel data of the left camera and the address position of (M, N) in the memory M16 are located at the address position of (X+M-1, Y+N-1) in the memory M12. The pixel data of the first registration mark is inconsistent (step S197, No), from the address of (X, Y) at the time to the address of the left camera 210L of the address of (X+c-1, Y+d-1) 2 The camera data of the mark position is different from the pixel data of the first registration mark, and the range from the (X, Y) address, the left first registration mark RM1 without the second mark position PM2 _L2 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 23: step S198), and loads the number of pixels a in the left-right direction of the camera in the memory M8 and the first registration mark in the memory M17. The number of pixels c in the left-right direction (steps S199 and S200) is repeated until the processing operation in steps S193 to S201 is repeated until the count value X exceeds "a-c+1" in step S201.

In this processing operation, if the count value X exceeds "a-c+1" (YES in step S201), the left-right direction end of the image data of the second mark position of the left camera 210L is exceeded, so the CPU 201 pairs the memory M5. The count value Y in the middle is incremented by 1 (step S202), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the number d of pixels in the vertical direction of the first registration mark in the memory M18 (steps S203, S204) The processing operations of steps S192 to S205 are repeated until the count value Y exceeds "b-d+1" in step S205.

In this processing operation, the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M12 and the bit of (M, N) in the memory M16 are confirmed. The pixel data of the first registration mark of the address position coincides (FIG. 22: YES in step S197), and the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 24: step S207), and loads the first from the memory M17. The number of pixels c in the left-right direction of one set of marks is set (step S208), and the processing operations of steps S195 to S209 are repeated until the count value M exceeds the number of pixels c in the left-right direction of the first registration mark in step S209.

When the count value M exceeds the number of pixels c in the left-right direction of the first registration mark (YES in step S209), the CPU 201 adds 1 to the count value N in the memory M14 (step S210), and loads the first set from the memory M18. The number of pixels d in the vertical direction of the quasi mark (step S211), the processing operations of steps S194 to S212 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first registration mark in step S212.

In this manner, the CPU 201 performs pattern matching on the pixel data of the first registration mark of c×d in the memory M16 for the image data of the a×b pixel in the memory M12 (the image data of the left second mark position). The count value N exceeds the number d of pixels in the vertical direction of the first registration mark (YES in step S212), and the (X, Y) address of the image data of the a×b pixel in the memory M12 is determined to (X+c). The range of the address of -1, Y+d-1) includes the pixel data of the first registration mark of c × d in the memory M16. That is, it is determined that the image of the second mark position PM2 captured by the left camera 210L includes the first registration mark RM1 (RM1 _L2 ).

In step S205, if the count value Y exceeds "b-d+1" (YES in step S205), the upper and lower ends of the image data of the second mark position of the left camera 210L are exceeded, and the CPU 201 determines the left camera. The image of the second mark position PM2 captured at 210L does not include the first registration mark RM1 (RM1 _L2 ), and the display 205 is erroneously displayed (step S206).

When the CPU 201 determines that the first registration mark RM1 _{L2 is} included in the image of the second mark position PM2 captured by the left camera 210L (YES in step S212), the CPU 201 loads the count value X in the memory M6 at that time (step S213). From the count value X loaded, the measurement position M1x2 _L in the X direction of the first registration mark RM1 _L2 is calculated and written in the address position in the X direction in the memory M20 (step S214). Further, the count value Y in the memory M5 at the time is loaded (step S215), and the measurement position M1y2 _L in the Y direction of the first registration mark RM1 _L2 is calculated from the loaded count value Y, and written in the memory. The address position of the Y direction in M20 (step S216, refer to FIG. 68B).

Further, the measurement position M1x2 _L in the X direction of the registration mark RM1 _L2 is obtained from the position in the left-right direction in which the left camera 210L is provided and the count value X, and the measurement position M1y2 _{L in the} Y direction is from the second mark position PM2. And the count value Y is obtained.

Then, the CPU 201 loads the measurement position M1y1 _L in the Y direction of the first registration mark RM1 _L1 of the first mark position PM1 from the address position in the Y direction of the memory M19 (FIG. 25: Step S217), and the memory from the memory M21, the reference position M1y1r in the Y direction of the first registration mark RM1 at the first mark position PM1 is loaded (step S218), and the measurement position M1y1 _L in the Y direction from the first registration mark RM1 _L1 of the first mark position PM1 The reference position M1y1r in the Y direction of the first registration mark RM1 of the first mark position PM1 is calculated, and the deviation amount ΔM1y1 _L of the first registration mark RM1 _L1 of the first mark position PM1 in the Y direction is obtained (refer to FIG. 66B). The amount of deviation ΔM1y1 _L in the Y direction of the first registration mark RM1 _L1 obtained is written in the memory M22 (step S219).

Further, the CPU 201 loads the measurement position M1y1 _L in the Y direction of the first registration mark RM1 _L1 of the first mark position PM1 from the address position in the Y direction of the memory M19 (step S220), and from the Y of the memory M20. The address position of the direction is the measurement position M1y2 _L in the Y direction of the first registration mark RM1 _L2 at the second mark position PM2 (step S221), and the Y of the first registration mark RM1 _L1 from the first mark position PM1. measurement position M1y1 direction _L, Save Operators second mark position PM2 first register mark in the Y direction RM1 _L2 of the measurement position M1y2 _L, obtains the distance between the left first registration mark LM1 _L (refer to FIG. 70 (a) The distance LM1 _L between the first registration marks thus obtained is written in the memory M23 (step S222).

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 26: step S223), sets the count value X in the memory M6 to 1 (step S224), and sets the count value N in the memory M14. If it is 1 (step S225), the count value M in the memory M15 is set to 1 (step S226).

Then, the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M11 is loaded (step S227), and the (M, N) in the memory M16 is loaded. The pixel data of the first registration mark of the address position (step S228), confirming the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the loaded memory M11 Whether or not the pixel data of the address position of (M, N) in the memory M16 coincides (step S229, refer to FIG. 67A).

Here, since the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M11 and the address position of (M, N) in the memory M16 are The pixel data of the first registration mark is inconsistent (step S229, No), from the address of the (X, Y) address at the time to the address of the right camera 210R of the address of (X+c-1, Y+d-1) The image data of any of the image data at the mark position is different from the pixel data of the first registration mark. The range from the address of (X, Y) is the right first registration mark RM1 without the first mark position PM1. _R1 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 27: Step S230), and loads the number of pixels a in the left-right direction of the camera in the memory M8 and the first registration mark in the memory M17. The number of pixels c in the left-right direction (steps S231 and S232) is repeated until the processing of steps S225 to S233 is performed until the count value X exceeds "a-c+1" in step S231.

In this processing operation, if the count value X exceeds "a-c+1" (YES in step S233), the left-right direction end of the image data of the first mark position of the right camera 210R is exceeded, so the CPU 201 pairs the memory M5. The count value Y in the middle is incremented by 1 (step S234), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the number of pixels d in the vertical direction of the first registration mark in the memory M18 (steps S235, S236) The processing operations of steps S224 to S237 are repeated until the count value Y exceeds "b-d+1" in step S237.

In this processing operation, the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M11 and the bit of (M, N) in the memory M16 are confirmed. The pixel data of the first registration mark of the address position coincides (FIG. 26: YES in step S229), and the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 28: step S239), and loads the first from the memory M17. The number of pixels c in the left-right direction of one set of marks is set (step S240), and the processing operations of steps S227 to S241 are repeated until the count value M exceeds the first register in step S241. The number of pixels in the left and right direction of the mark is up to c.

When the count value M exceeds the number c of pixels in the left-right direction of the first registration mark (YES in step S241), the CPU 201 adds 1 to the count value N in the memory M14 (step S242), and loads the first set from the memory M18. The number of pixels d in the vertical direction of the quasi mark (step S243), the processing operations of steps S226 to S244 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first registration mark in step S244.

In this manner, the CPU 201 performs pattern matching on the pixel data of the first registration mark of c×d in the memory M16 with respect to the image data of the a×b pixel in the memory M11 (the image data of the right first mark position). The count value N exceeds the number of pixels d in the vertical direction of the first registration mark (YES in step S244), and the (X, Y) address of the image data of the a×b pixel in the memory M11 is determined to (X+c). The range of the address of -1, Y+d-1) includes the pixel data of the first registration mark of c × d in the memory M16. In other words, it is determined that the first registration mark RM1 (RM1 _R1 ) is included in the image of the first mark position PM1 captured by the right camera 210R.

In addition, if the count value Y exceeds "b-d+1" (YES in step S237), the upper and lower ends of the image data of the first mark position of the right camera 210R are exceeded, and the CPU 201 determines that the right camera is in step S237. The image of the first mark position PM1 captured by 210R does not include the first registration mark RM1 (RM1 _R1 ), and the display 205 is erroneously displayed (step S238).

When the CPU 201 determines that the image of the first mark position PM1 imaged by the right camera 210R includes the first registration mark RM1 _R1 (YES in step S244), the CPU 201 loads the count value X in the memory M6 at that time (step S245). The measurement position M1x1 _R in the X direction of the first registration mark RM1 _R1 is calculated from the count value X loaded, and is written in the address position in the X direction in the memory M24 (step S246). Further, the count value Y in the memory M5 at the time is loaded (step S247), and the measurement position M1y1 _R in the Y direction of the first registration mark RM1 _R1 is calculated from the loaded count value Y, and is written in the memory. The address position of the Y direction in M24 (step S248, refer to FIG. 67B).

And the count value Y is obtained.

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 29: step S249), sets the count value X in the memory M6 to 1 (step S250), and sets the count value N in the memory M14. If it is 1 (step S251), the count value M in the memory M15 is set to 1 (step S252).

Then, the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M13 is loaded (step S253), and the (M, N) in the memory M16 is loaded. The pixel data of the first registration mark of the address position (step S254), confirming the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the loaded memory M13 Whether or not the pixel data of the address position of (M, N) in the memory M16 coincides (step S255, refer to FIG. 69A).

Here, since the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M13 and the address position of (M, N) in the memory M16 are The pixel data of the first registration mark is inconsistent (step S255, No), from the address of (X, Y) at the time to the address of the right camera 210R of the address of (X+c-1, Y+d-1) 2 The image data of the image data at the mark position is different from the pixel data of the first registration mark, and the range from the (X, Y) address, the right first registration mark RM1 without the second mark position PM2 _R2 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 30: Step S256), loads the number of pixels a in the left-right direction of the camera in the memory M8, and the first registration mark in the memory M17. The number of pixels c in the left-right direction (steps S257 and S258) is repeated until the processing of steps S251 to S259 is performed until the count value X exceeds "a-c+1" in step S259.

In this processing operation, if the count value X exceeds "a-c+1" (YES in step S259), the left-right direction end of the image data of the second mark position of the right camera 210R is exceeded, so the CPU 201 pairs the memory M5. The count value Y in the middle is incremented by 1 (step S260), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the number of pixels d in the vertical direction of the first registration mark in the memory M18 (steps S261, S262) The processing operations of steps S250 to S263 are repeated until the count value Y exceeds "b-d+1" in step S263.

In this processing operation, the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M13 and the bit of (M, N) in the memory M16 are confirmed. The pixel data of the first registration mark of the address position coincides (FIG. 29: YES in step S255), and the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 31: step S265), and loads the first from the memory M17. The number of pixels c in the left-right direction of one set of marks is set (step S266), and the processing operations of steps S253 to S267 are repeated until the count value M exceeds the number of pixels c in the left-right direction of the first registration mark in step S267.

If the count value M exceeds the pixel in the left and right direction of the first registration mark The number c (YES in step S267), the CPU 201 adds 1 to the count value N in the memory M14 (step S268), and loads the number d of pixels in the vertical direction of the first registration mark from the memory M18 (step S269), and repeats The processing operations of steps S252 to S270 are continued until the count value N exceeds the number of pixels d in the vertical direction of the first registration mark in step S270.

In this manner, the CPU 201 performs pattern matching on the pixel data of the first registration mark of c×d in the memory M16 with respect to the image data of the a×b pixel in the memory M13 (the image data of the right second mark position). The count value N exceeds the number of pixels d in the vertical direction of the first registration mark (YES in step S270), and the (X, Y) address of the image data of the a×b pixel in the memory M13 is determined to (X+c). The range of the address of -1, Y+d-1) includes the pixel data of the first registration mark of c × d in the memory M16. In other words, it is determined that the image of the second mark position PM2 captured by the right camera 210R includes the first registration mark RM1 (RM1 _R2 ).

In addition, if the count value Y exceeds "b-d+1" (YES in step S263), the upper and lower ends of the image data of the second mark position of the right camera 210R are exceeded, and the CPU 201 determines that the right camera is in step S263. The image of the second mark position PM2 captured by 210R does not include the first registration mark RM1 (RM1 _R2 ), and the display 205 is erroneously displayed (step S264).

When the CPU 201 determines that the first registration mark RM1 _{R2 is} included in the image of the second mark position PM2 captured by the right camera 210R (YES in step S270), the CPU 201 loads the count value X in the memory M6 at that time (step S271). From the count value X loaded, the measurement position M1x2 _R in the X direction of the first registration mark RM1 _R2 is calculated and written in the address position in the X direction in the memory M25 (step S272). Further, the count value Y in the memory M5 at the time is loaded (step S273), and the measurement position M1y2 _R in the Y direction of the first registration mark RM1 _R2 is calculated from the loaded count value Y, and written in the memory.

Then, when the CPU 201 confirms the current rotation phase ψ _{R of the} blanket cylinder, it reaches the printing start position ψ _{ST of the} blanket cylinder (YES in step S320), and outputs a loading command to the drum loading and unloading device 236 (step S321) to make the blanket. The drum 2 contacts the plate cylinder 1. Then, the CPU 201 loads the reference rotational speed VPr of the plate cylinder from the memory M39 (step S322), and presses the reference rotational speed VPr of the loaded plate cylinder to the plate cylinder drive motor driver 218 via D/A. The converter 221 outputs (step S323). Thereby, the plate cylinder 1 starts to rotate at the reference rotation speed VPr, and the ink from the plate cylinder 1 starts to be transferred to the blanket cylinder 2.

While the ink is being transferred from the plate cylinder 1 to the blanket cylinder 2, the CPU 201 rotates the phase detecting counter 225 from the blanket cylinder to load the count value (FIG. 38: step S324), and the blanket cylinder rotation phase detection loaded therefrom. The current rotation phase ψ _{R of the} blanket cylinder is calculated by the count value of the counter 225 (step S325), and the printing end position _{END END of the} blanket cylinder is loaded from the memory M47 (step S326), and the current rotation of the blanket cylinder is confirmed. The phase ψ _R is reached at the printing end position ψ _{END of the} blanket cylinder (step S327).

When the CPU 201 confirms the current rotation phase ψ _R of the blanket cylinder, it reaches the printing end position _{END END of the} blanket cylinder (YES in step S327), and outputs a removal command to the drum loading and unloading device 236 (step S328) to make the blanket cylinder. 2 Leave the plate cylinder 1. That is, the drum is removed. Thereby, the ink from the plate cylinder 1 is transferred from the printing start position ψ _{ST of the} blanket cylinder 2 to the printing end position _{END END} .

[Down of blanket roller]

When the ink transfer from the plate cylinder 1 to the blanket cylinder 2 is completed, the CPU 201 outputs a stop command to the plate cylinder drive motor driver 218 (step S329) to stop the rotation of the plate cylinder 1. Then, the phase detecting counter 225 is rotated from the blanket cylinder, and the count value is loaded (FIG. 39: step S330), and the blanket cylinder loaded from here rotates the count value of the phase detecting counter 225 to calculate the current rotational phase of the blanket cylinder. ψ _R (step S331), from the memory M48, the movement start position ψ _{MST of the} blanket cylinder is loaded (step S332), and the current rotation phase ψ _{R of the} blanket cylinder is confirmed, and whether or not the movement start position of the blanket cylinder is reached ψ _MST (Step S333).

When the CPU 201 confirms the current rotation phase ψ _R of the blanket cylinder, it reaches the movement start position ψ _MST of the blanket cylinder (YES in step S333), and outputs a lowering command to the blanket cylinder lift cylinder valve 234 (step S334). . Thereby, the blanket cylinder lifting pneumatic cylinder 233 operates, and the blanket cylinder 2 descends to the printing table 3 (refer to FIG. 72).

[Motion roller moving up and down]

Next, the CPU 201 loads the vertical direction moving speed vB _{M of the} blanket cylinder from the memory M49 (step S335), moves the blanket motor for the vertical direction of the blanket cylinder, and moves the forward rotation command and the blanket roller in the vertical direction. vB _M is output via the D/A converter 231 (step S336). As a result, the blanket cylinder 2 rotates and moves in the vertical direction on the downstream side in the vertical direction, that is, in the direction of the printed matter 4A on the printing table 4, in the vertical direction moving speed vB _M .

Next, the CPU 201 writes the position of the blanket cylinder in the vertical direction in the memory M50, and indicates that the uncompleted value "2" is corrected based on the phase deviation of the rotational phase (FIG. 40: Step S337). Then, in the movement of the blanket cylinder 2 on the downstream side in the up-and-down direction, the position detecting counter 230 is loaded from the vertical direction of the blanket cylinder, and the count value is loaded (step S338), and the position of the blanket cylinder loaded in the up-and-down direction is loaded. The count value of the detection counter 230 is calculated, the current vertical position PBM _{R of the} blanket cylinder is calculated, written in the memory M52 (step S339), and the corrected print start position PRT _ST ' is loaded from the memory M33 (step S340). It is confirmed whether or not the current vertical position position PBM _R of the blanket cylinder calculated in step S339 has reached the corrected printing start position PRT _ST ' (step S341).

[Rotary phase adjustment of blanket cylinder]

The CPU 201 repeats the processing operations of steps S342 (FIG. 41) to S362 (FIG. 42) until the step S341 confirms the current vertical position PBM _{R of the} blanket cylinder and reaches the corrected printing start position PRT _ST '. In the processing of steps S342 to S362, the rotation phase of the blanket cylinder is adjusted. The adjustment of the rotational phase of this blanket cylinder is performed as follows.

The CPU 201 loads the current vertical position PBM _{R of the} blanket cylinder from the memory M52 (FIG. 41: Step S342), and loads the deviation amount of the first registration mark in the Y direction from the memory M27 to the Y direction. Y1 (step S343), the amount of deviation ΔY2 in the Y direction of the second registration mark at the first mark position is loaded from the memory M74 (step S344), and the vertical position PBM _R of the blanket cylinder is added. The amount of deviation ΔY1 in the Y direction of the first registration mark at the mark position and the deviation amount ΔY2 in the Y direction of the second registration mark at the first mark position are used to obtain the current up and down position of the corrected blanket cylinder. PBM _R ', the current vertical direction position PBM _R ' of the corrected blanket cylinder obtained in the above is written in the memory M53 (step S345).

Then, from the memory M54, the up-and-down direction of the blanket cylinder is loaded - the rotation phase conversion table of the blanket cylinder (step S346), and the position of the blanket cylinder loaded in the up-and-down direction - the rubber that should be present The rotation phase conversion table of the cloth cylinder determines the rotation phase ψm of the blanket cylinder from the current vertical position PBM _R ' of the corrected blanket cylinder (step S347).

Then, the CPU 201 rotates the phase detecting counter 225 from the blanket cylinder to load the count value (step S348), and the blanket cylinder rotated from the phase of the phase detecting counter 225 is loaded to determine the current rotational phase of the blanket cylinder. _R (step S349). Then, from the rotational phase ψm of the blanket cylinder obtained in step S347, the current rotational phase ψ _{R of the} blanket cylinder is subtracted, and the current rotational phase difference Δψ _{R is} obtained, and the current rotational phase difference Δψ obtained therefrom is obtained. _{R is} written in the memory M56 (step S350).

Next, the CPU 201 obtains the absolute value of the rotational phase difference Δψ _R of the blanket cylinder from the current rotational phase difference Δψ _R of the blanket cylinder obtained in step S350 (step S351), and loads the eraser from the memory M58. The allowable value α of the rotational phase difference of the cloth cylinder (step S352), and confirm whether the absolute value of the current rotational phase difference Δψ _R of the blanket cylinder is equal to or less than the allowable value α of the rotational phase difference of the blanket cylinder (FIG. 42: Step S353).

Here, if the absolute value of the rotational phase difference Δψ _R of the blanket cylinder is not equal to or less than the allowable value α of the rotational phase difference of the blanket cylinder (NO in step S353), the CPU 201 loads the blanket cylinder from the memory M59. The current rotation phase difference-rotation speed correction value conversion table (step S354), and from the memory M56, the current rotation phase difference Δψ _{R of the} blanket cylinder is loaded (step S355), and the current rotation phase of the blanket cylinder is utilized. The correction value conversion table of the difference-rotation speed obtains the correction value ΔV of the rotation speed from the current rotational phase difference Δψ _{R of the} blanket cylinder (step S356).

Then, the CPU 201 loads the reference rotation speed VBr of the blanket cylinder from the memory M37 (step S357), adds the correction value ΔV of the rotation speed to the reference rotation speed VBr of the blanket cylinder, and obtains the corrected blanket cylinder. The rotation speed VBr' (step S358), the obtained rotation speed VBr' of the blanket blanket is output to the blanket cylinder drive motor driver 223 via the D/A converter 226 (step S359), and the process returns to the step S338 (Figure 40), Repeat the same action.

Thereby, the rotational speed of the blanket cylinder 2 is adjusted so that the absolute value of the rotational phase difference Δψ _R of the blanket cylinder now satisfies the allowable value α of the rotational phase difference of the blanket cylinder.

Then, if the absolute value of the rotational phase difference Δψ _R of the blanket cylinder is equal to or less than the allowable value α of the rotational phase difference of the blanket cylinder (FIG. 42: YES in step S353), the CPU 201 loads the eraser from the memory M37. The reference rotation speed VBr of the cloth drum (step S360), and the reference rotation speed VBr of the loaded blanket cylinder is output to the blanket cylinder drive motor driver 223 via the D/A converter 226 (step S361). The memory M50 is written as "1" as a value indicating that the phase deviation correction is completed in accordance with the vertical position and the rotational phase of the blanket cylinder (step S362).

The CPU 201 repeats the processing operations of steps S342 to S362 until the current vertical position PBM _{R of the} blanket cylinder reaches the corrected printing start position PRT _ST ', and the absolute rotation phase difference Δψ _R of the blanket cylinder is now in step S353. When the value does not become the allowable value α of the rotational phase difference of the blanket cylinder, the processing of steps S360 to S362 is not advanced. At this time, in the memory M50, the uncompleted value is corrected as the phase deviation correction based on the vertical position and the rotational phase of the blanket cylinder, and "2" is maintained.

When the CPU 201 confirms the current vertical position PBM _{R of the} blanket cylinder, it reaches the corrected print start position PRT _ST ' (FIG. 40: Yes in step S341), loads the value written in the memory M50 (step S363), and confirms writing. Whether the value entered in the memory M50 is "1" (FIG. 43: Step S364). Here, if the value written in the memory M50 is not "1" (NO in step S364), an error is displayed on the display 205 (step S377), and the value written in the memory M50 is "1" (YES in step S364) It is judged that the phase deviation correction in accordance with the vertical position and the rotational phase of the blanket cylinder is completed.

When the CPU 201 determines that the phase deviation correction in accordance with the vertical position and the rotational phase of the blanket cylinder is completed (YES in step S364), the rotation speed VBp of the blanket cylinder being loaded is loaded from the memory M38 (step S365). The rotational speed VBp of the blanket cylinder in the loaded printing is output to the blanket cylinder drive motor driver 223 via the D/A converter 226 (step S366). Thereby, the blanket cylinder 2 starts to rotate at the rotational speed VBp of the blanket cylinder in printing (refer to FIG. 73). In other words, from the corrected printing start position PRT _ST ', while rotating at the rotation speed VBp of the blanket cylinder, the blanket cylinder 2 moves to the downstream side in the vertical direction, and the printed matter 4A on the printing table 3 is The circuit (the second circuit) is printed.

Then, the CPU 201 loads the count value from the up-and-down position detecting counter 230 of the blanket cylinder (step S367), and counts the count value of the up-and-down direction position detecting counter 230 of the blanket cylinder loaded therefrom, and calculates the current blanket cylinder. In the up-and-down direction position PBM _R (step S368), the print end position PRT _{END is} loaded from the memory M36 (step S369), and the current vertical position PBM _{R of the} blanket cylinder is checked to see whether or not the print end position PRT _END has been reached (step S370). ).

When the CPU 201 confirms the current vertical position PBM _{R of the} blanket cylinder, it reaches the printing end position PRT _END (YES in step S370), and outputs a stop command to the blanket cylinder drive motor driver 223 (FIG. 41: Step S371) to make the eraser. The rotation of the cloth drum 2 is stopped (refer to Fig. 74). Then, the air cylinder 233 for the blanket cylinder lifting and lowering outputs a rising command (step S372), and the blanket cylinder 2 is lifted from the printing table 3 (refer to FIG. 75).

Then, the CPU 201 loads the upper and lower direction moving speed vB _{M of the} blanket cylinder from the memory M49 (step S373), and moves the motor driver 228 to the blanket cylinder up and down direction, and moves the reverse rotation command and the blanket cylinder in the vertical direction by the speed vB. _M is output via the D/A converter 231 (step S374). As a result, in the state where the blanket cylinder 2 stops rotating, the upstream side in the vertical direction, that is, the side where the plate cylinder 1 is located, the upper and lower direction moving speed vB _M starts to move.

When the blanket cylinder 2 moves to the upstream side in the up-and-down direction, the origin position detector 232 in the vertical direction of the blanket cylinder is opened (YES in step S375), that is, the first before returning to the blanket cylinder 1 to start moving. At the position (original position), the motor driver 228 for moving the blanket cylinder up and down direction outputs a stop command (step S376). Thereby, the movement of the blanket cylinder 2 in the up and down direction is stopped (refer to FIG. 76).

Thereby, the deviation amount ΔY2 in the Y direction of the second registration mark of the first mark position PM1 is ΔY2=0, and the expansion ratio η2 between the second registration marks is η2=1, and the printing is performed. The printed matter 4A of the first circuit performs printing of the circuit (secondary circuit), and the first printed matter 4B in which four second registration marks RM2 are simultaneously printed as shown in FIG. 3 is obtained.

[teaching after printing]

The operator is thus obtained with the 4th registration mark RM2 printed at the same time. After the print 4AB, the teaching switch 209 after the end of printing is turned on.

When the CPU 201 of the platform print control device 200 turns on the teaching switch 209 after the end of printing (FIG. 45: YES in step S377), the rotation speed Vc of the camera moving motor is loaded from the memory M1 (step S378), and the camera moves for the camera. The motor driver 212 outputs the forward rotation command and the rotational speed Vc of the camera moving motor via the D/A converter 215 (step S379). Thereby, the camera moving motor 211 is rotated forward at the rotational speed Vc, and the first position shown in FIG. 3 is used as the origin position, and the left camera 210L and the right camera 210R are simultaneously moved to the left side of the printing table 3.

The CPU 201 loads the count value of the camera position detecting counter 214 during the movement of the left camera 210L and the right camera 210R (step S380), and calculates the left camera 210L and the right camera 210R from the count value of the camera position detecting counter 214. The current position PCM _R (step S381), the first mark position PM1 is loaded from the memory M4 (step S382), and it is confirmed whether the current position PCM _{R of the} left camera 210L and the right camera 210R has reached the first mark position PM1 (step S383). ).

When the CPU 201 confirms that the current position PCM _{R of the} left camera 210L and the right camera 210R has reached the first mark position PM1 (YES in step S383), the CPU 201 outputs a stop command to the camera movement motor driver 212 (step S384), and stops the left camera 210L and the right camera. The movement of the 210R. Then, an imaging command is output to the left camera 210L and the right camera 210R (step S385), and the left camera 210L captures the area including the second registration mark RM2 _R1 mounted on the to-be-printed object 4B of the printing table 3 to the right camera. 210R, an area including the second registration mark RM2 _R1 mounted on the to-be-printed object 4B of the printing table 3 is taken.

Then, the CPU 201 sends a transmission command of the image data to the left camera 210L (FIG. 46: Step S386), and if the image data is sent from the left camera 210L in response to the transmission command (YES in step S387), the memory M5 is used. The count value Y is set to 1 (step S388), the count value X in the memory M6 is set to 1 (step S389), and the image data from the left camera 210L at the pixel position specified by the count values X and Y is written.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (Yes in step S393), the count value Y in the memory M5 is incremented by 1 (step S394), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S395) repeats the processing operations of steps S389 to S396 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S396.

Thereby, in the memory M7, the image data of the a×b pixel from the left camera 210L of the first mark position PM1 is memorized. Here, as shown in FIG. 77A, the image data of the second registration mark RM2 _L1 including the to-be-printed object 4B is stored in the memory M7 as image data of a × b pixels. Further, in the memory M62, as shown in Fig. 77A, the pixel data of e × f of the second registration mark RM2 is stored as pattern matching data.

Next, the CPU 201 sends the image data to the right camera 210R. If the transmission command is sent from the right camera 210R (YES in step S398), the count command Y in the memory M5 is set to 1 (step S399), The count value X in the memory M6 is set to 1 (step S400), and the image data from the right camera 210R at the pixel position specified by the count values X and Y is written in the (X, Y) of the memory M11.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (YES in step S404), the count value Y in the memory M5 is incremented by one (step S405), and the vertical direction of the camera in the memory M9 is loaded. The pixel value b (step S406) repeats the processing operations of steps S400 to S407 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S407.

Thereby, in the memory M11, the image data of the a×b pixel from the right camera 210R of the first mark position PM1 is memorized. Here, as shown in FIG. 78A, the image data of the second registration mark RM2 _R1 including the to-be-printed object 4B is stored in the memory M11 as image data of the a×b pixel.

Next, the CPU 201 loads the rotational speed Vc of the camera moving motor from the memory M1 (FIG. 48: Step S408), and passes the reverse rotation command and the rotational speed Vc of the camera moving motor to the camera moving motor driver 212 via D/. The A converter 215 outputs (step S409). Thereby, the camera moves The motor 211 is reversed at the rotational speed Vc, and is stopped by the left camera 210L and the right camera 210R at the first mark position PM1 in FIG. 3, and simultaneously moved to the printing table 3 to the right.

The CPU 201 loads the count value of the camera position detecting counter 214 during the movement of the left camera 210L and the right camera 210R (step S410), and calculates the left camera 210L and the right camera 210R from the count value of the camera position detecting counter 214. The current position PCM _R (step S411), the second mark position PM2 is loaded from the memory M10 (step S412), and it is confirmed whether the current position PCM _{R of the} left camera 210L and the right camera 210R has reached the second mark position PM2 (step S413). ).

When the CPU 201 confirms that the current position PCM _{R of the} left camera 210L and the right camera 210R has reached the second mark position PM2 (YES in step S413), the CPU 201 outputs an imaging command to the left camera 210L and the right camera 210R (step S414), and takes a picture with the left camera 210L. The area including the second registration mark RM2 _L2 on the to-be-printed object 4B is imaged by the right camera 210R, and the area including the second registration mark RM2 _R2 on the printed matter 4B is imaged.

Then, the CPU 201 sends a transmission command of the image data to the left camera 210L (step S415), and if the image data is sent from the left camera 210L in response to the transmission command (YES in step S416), the count value Y in the memory M5 is obtained. 1 is set (step S417), the count value X in the memory M6 is set to 1 (FIG. 49: step S418), and the image data from the left camera 210L at the pixel position specified by the count values X and Y is written. The address position of (X, Y) of the memory M12 (step S419).

Then, the CPU 201 adds the count value X in the memory M6. 1 (step S420), the number of pixels a in the left-right direction of the camera in the memory M8 is loaded (step S421), and the processing operations of steps S419 to S422 are repeated until the count value X exceeds the pixel in the left-right direction of the camera in step S422. The value is a.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (YES in step S422), the count value Y in the memory M5 is incremented by 1 (step S423), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S424) repeats the processing operations of steps S418 to S425 until the count value Y exceeds the pixel value b of the vertical direction of the camera in step S425.

Thereby, in the memory M12, the image data of the a×b pixel from the left camera 210L at the second mark position PM2 is memorized. Here, as shown in FIG. 79A, the image data of the second registration mark RM2 _L2 including the printed matter 4B is stored in the memory M12 as image data of a × b pixels.

Then, if the count value X exceeds the pixel value a in the left-right direction of the camera (YES in step S433), the count value Y in the memory M5 is incremented by one (step S434), and is loaded in the vertical direction of the camera in the memory M9. The pixel value b (step S435) repeats the processing operations of steps S429 to S436 until the count value Y exceeds the pixel value b in the vertical direction of the camera in step S436.

Thereby, in the memory M13, the image data of the a×b pixel from the right camera 210R of the second mark position PM2 is memorized. Here, as shown in FIG. 80A, the image data of the second registration mark RM2 _R2 including the to-be-printed object 4B is stored in the memory M13 as image data of a × b pixels.

Then, the CPU 201 continues the movement of the left camera 210L and the right camera 210R, and if the origin position detector 216 of the camera detects that the left camera 210L and the right camera 210R are returned to the origin position (initial position) (step S437, yes) The camera movement motor driver 212 sends a stop command (step S438) to stop the movement of the left camera 210L and the right camera 210R.

[Detecting the position of the second registration mark by pattern matching]

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 51: step S439), sets the count value X in the memory M6 to 1 (step S440), and sets the count value N in the memory M14. If it is 1 (step S441), the count value M in the memory M15 is set to 1 (step S442).

Then, the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M7 is loaded (step S443), and the (M, N) in the memory M62 is loaded. Pixel data for the second registration mark of the address location (step S444), confirm the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the loaded memory M7, and the bit of (M, N) in the memory M62. Whether the pixel data of the address location is identical (step S445, refer to FIG. 77A).

Here, the pixel data of the left camera and the address position of (M, N) in the memory M62 are located at the address position of (X+M-1, Y+N-1) in the memory M7. The pixel data of the second registration mark is inconsistent (step S445, No), from the address of the (X, Y) address at the time to the address of the left camera 210L of the address of (X+e-1, Y+f-1) The image data of any of the image data at the mark position is different from the pixel data of the second registration mark, and the range from the address of (X, Y) is the left second registration mark RM2 of the first mark position PM1. _L1 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 52: step S446), and loads the number of pixels a in the left-right direction of the camera in the memory M8 and the second registration mark in the memory M63. The number of pixels e in the left-right direction (steps S447 and S448) is repeated until the processing of steps S441 to S449 is performed until the count value X exceeds "a-e+1" in step S449.

In this processing operation, if the count value X exceeds "a-e+1" (YES in step S449), the left-right direction end of the image data of the first mark position of the left camera 210L is exceeded, so the CPU 201 pairs the memory M5. The count value Y in the middle is incremented by 1 (step S450), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the number of pixels f in the vertical direction of the second registration mark in the memory M64 (steps S451, S452) The processing operations of steps S440 to S453 are repeated until the count value Y exceeds "b-f+1" in step S453.

In this processing operation, if the address information of the left camera of (X+M-1, Y+N-1) in the memory M7 is confirmed, and the memory is confirmed. The pixel data of the second registration mark of the address position of (M, N) in the body M62 coincides (FIG. 51: YES in step S445), and the CPU 201 adds 1 to the count value M in the memory M15 (FIG. 53: Step S455), the number of pixels e in the left-right direction of the second registration mark is loaded from the memory M63 (step S456), and the processing operations of steps S443 to S457 are repeated until the count value M exceeds the second registration mark in step S457. The number of pixels e in the left and right direction is up.

When the count value M exceeds the number of pixels e in the left-right direction of the second registration mark (YES in step S457), the CPU 201 adds 1 to the count value N in the memory M14 (step S458), and loads the second set from the memory M64. The number of pixels f in the vertical direction of the quasi mark (step S459), the processing operations of steps S442 to S460 are repeated until the count value N exceeds the number f of pixels in the vertical direction of the second registration mark in step S460.

In this manner, the CPU 201 performs pattern matching on the pixel data of the second registration mark of e×f in the memory M62 for the image data of the a×b pixel in the memory M7 (the image data of the left first mark position). The count value N exceeds the number f of pixels in the vertical direction of the second registration mark (YES in step S460), and the (X, Y) address of the image data of the a×b pixel in the memory M7 is determined to (X+e). The range of the address of -1, Y+f-1) includes the pixel data of the second registration mark of e × f in the memory M62. That is, it is determined that the image of the first mark position PM1 captured by the left camera 210L includes the second registration mark RM2 (RM2 _L1 ).

In addition, if the count value Y exceeds "b-f+1" in step S453 (YES in step S453), the upper and lower ends of the image data of the first mark position of the left camera 210L are exceeded, and the CPU 201 determines that the camera is left. The image of the first mark position PM1 taken at 210L does not include the second registration mark RM2 (RM2 _L1 ), and the display 205 is erroneously displayed (step S454).

When the CPU 201 determines that the image of the first mark position PM1 captured by the left camera 210L includes the second registration mark RM2 _L1 (YES in step S460), the CPU 201 loads the count value X in the memory M6 at that time (step S461). From the count value X loaded, the measurement position M2x1 _L in the X direction of the second registration mark RM2 _L1 is calculated and written in the address position in the X direction in the memory M65 (step S462). Further, the count value Y in the memory M5 at the time is loaded (step S463), and the measurement position M2y1 _L in the Y direction of the second registration mark RM2 _L1 is calculated from the loaded count value Y, and written in the memory. The address position in the Y direction in M65 (step S464, refer to FIG. 77B).

Further, the measurement position M2x1 _L in the X direction of the registration mark RM2 _L1 is obtained from the position in the left-right direction in which the left camera 210L is provided and the count value X, and the measurement position M2y1 _{L in the} Y direction is from the first mark position PM1. And the count value Y is obtained.

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 54: step S465), sets the count value X in the memory M6 to 1 (step S466), and sets the count value N in the memory M14. If it is 1 (step S467), the count value M in the memory M15 is set to 1 (step S468).

Then, the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M12 is loaded (step S469), and the (M, N) in the memory M62 is loaded. The pixel data of the second registration mark of the address position (step S470), confirming the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the loaded memory M12 And (M,N) in memory M62 Whether the pixel data of the address position is identical (step S471, refer to Fig. 79A).

Here, since the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M12 and the address position of (M, N) in the memory M62 are The pixel data of the second registration mark is inconsistent (step S471, No), from the address of the (X, Y) address at the time to the address of the left camera 210L of the address of (X+e-1, Y+f-1) 2 The camera data of the marked position is different from the pixel data of the second registration mark. The range from the (X, Y) address, the left second registration mark RM2 without the second mark position PM2 _L2 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 55: Step S472), loads the number of pixels a in the left-right direction of the camera in the memory M8, and the second registration mark in the memory M63. The number of pixels e in the left-right direction (steps S473 and S474) is repeated until the processing of steps S467 to S475 is performed until the count value X exceeds "a-e+1" in step S475.

In this processing operation, if the count value X exceeds "a-e+1" (YES in step S475), the left-right direction end of the image data of the second mark position of the left camera 210L is exceeded, so the CPU 201 pairs the memory M5. The count value Y in the middle is incremented by 1 (step S476), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the number of pixels f in the vertical direction of the second registration mark in the memory M64 (steps S477, S478) The processing operations of steps S466 to S479 are repeated until the count value Y exceeds "b-f+1" in step S479.

In this processing operation, the pixel data of the left camera of the address position of (X+M-1, Y+N-1) in the memory M12 and the bit of (M, N) in the memory M62 are confirmed. The pixel data of the second registration mark of the address position is identical (FIG. 54: Step S471, YES), and the CPU 201 counts the memory M15. The value M is incremented by one (FIG. 56: step S481), and the number of pixels e in the left-right direction of the second registration mark is loaded from the memory M63 (step S482), and the processing operations of steps S469 to S483 are repeated until step S483. The count value M exceeds the number of pixels e in the left-right direction of the second registration mark.

When the count value M exceeds the number of pixels e in the left-right direction of the second registration mark (YES in step S483), the CPU 201 adds 1 to the count value N in the memory M14 (step S484), and loads the second set from the memory M64. The number of pixels f in the vertical direction of the quasi mark (step S485), the processing operations of steps S468 to S486 are repeated until the count value N exceeds the number of pixels f in the vertical direction of the second registration mark in step S486.

In this manner, the CPU 201 performs pattern matching on the pixel data of the second registration mark of e×f in the memory M62 for the image data of the a×b pixel in the memory M12 (the image data of the left second mark position). The count value N exceeds the number f of pixels in the vertical direction of the second registration mark (YES in step S486), and the (X, Y) address of the image data of the a×b pixel in the memory M12 is determined to (X+e). The range of the address of -1, Y+f-1) includes the pixel data of the second registration mark of e × f in the memory M62. In other words, it is determined that the image of the second mark position PM2 captured by the left camera 210L includes the second registration mark RM2 (RM2 _L2 ).

In addition, if the count value Y exceeds "b-f+1" in step S479 (YES in step S479), the upper and lower ends of the image data of the second mark position of the left camera 210L are exceeded, and the CPU 201 determines that the left camera is The image of the second mark position PM2 captured at 210L does not include the second registration mark RM2 (RM2 _L2 ), and the display 205 is erroneously displayed (step S480).

When the CPU 201 determines that the image of the second mark position PM2 captured by the left camera 210L includes the second registration mark RM2 _L2 (YES in step S486), the CPU 201 loads the count value X in the memory M6 at that time (step S487). From the count value X loaded, the measurement position M2x2 _L in the X direction of the second registration mark RM2 _L2 is calculated and written in the address position in the X direction in the memory M66 (step S488). Further, the count value Y in the memory M5 at the time is loaded (step S489), and the measurement position M2y2 _L in the Y direction of the second registration mark RM2 _L2 is calculated from the loaded count value Y, and written in the memory. The address position of the Y direction in M66 (step S490, refer to FIG. 79B).

Further, the measurement position M2x2 _L in the X direction of the registration mark RM2 _L2 is obtained from the position in the left-right direction in which the left camera 210L is provided and the count value X, and the measurement position M2y2 _{L in the} Y direction is from the second mark position PM2. And the count value Y is obtained.

Then, the CPU 201 loads the measurement position M2y1 _L in the Y direction of the second registration mark RM2 _L1 of the first mark position PM1 from the address position in the Y direction of the memory M65 (FIG. 57: Step S491), and the memory from the memory M67, the reference position M2y1r in the Y direction of the second registration mark RM2 of the first mark position PM1 is loaded (step S492), and the measurement position M2y1 _L in the Y direction of the second registration mark RM2 _L1 from the first mark position PM1 The reference position M2y1r in the Y direction of the second registration mark RM2 of the first mark position PM1 is subtracted, and the deviation amount ΔM2y1 _L of the second registration mark RM2 _L1 of the first mark position PM1 in the Y direction is obtained (refer to FIG. 77B). The amount of deviation ΔM2y1 _L in the Y direction of the obtained second register mark RM2 _L1 is written in the memory M68 (step S493).

Further, the CPU 201 loads the measurement position M2y1 _L in the Y direction of the second registration mark RM2 _L1 of the first mark position PM1 from the address position in the Y direction of the memory M65 (step S494), and from the Y of the memory M66. The address position of the direction is the measurement position M2y2 _L in the Y direction of the second registration mark RM2 _L2 at the second mark position PM2 (step S495), and the Y of the second registration mark RM2 _L1 from the first mark position PM1. measurement position M2y1 direction _L, Save Operators second mark position PM2 of the second register mark in the Y direction RM2 _L2 of the measurement position M2y2 _L, obtains the distance between the left and the second registration mark LM2 _L (refer to FIG. 81 (a) The distance LM2 _L between the obtained left second registration marks is written in the memory M69 (step S496).

Next, the CPU 201 sets the count value Y in the memory M5 to 1 (FIG. 58: step S497), sets the count value X in the memory M6 to 1 (step S498), and sets the count value N in the memory M14. If it is 1 (step S499), the count value M in the memory M15 is set to 1 (step S500).

Then, the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M11 is loaded (step S501), and the (M, N) in the memory M62 is loaded. The pixel data of the second registration mark of the address position (step S502), confirming the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the loaded memory M11 Whether or not the pixel data of the address position of (M, N) in the memory M62 coincides (step S503, refer to FIG. 78A).

Here, since the pixel data of the right camera of the address position of (X+M-1, Y+N-1) in the memory M11 and the address position of (M, N) in the memory M62 are The pixel data of the second registration mark is inconsistent (step S503, No), from the address of (X, Y) at the time to the address of the right camera 210R of the address of (X+e-1, Y+f-1) 1 The camera data of the mark position is different from the pixel data of the 2nd registration mark, and the range from the (X, Y) address is the right first registration mark RM2 without the first mark position PM1. _R1 , the CPU 201 adds 1 to the count value X in the memory M6 (FIG. 59: Step S504), loads the number of pixels a in the left-right direction of the camera in the memory M8, and the second registration mark in the memory M63. The number of pixels e in the left-right direction (steps S505 and S506) is repeated until the processing of steps S499 to S507 is performed until the count value X exceeds "a-e+1" in step S507.

In this processing operation, if the count value X exceeds "a-e+1" (YES in step S507), the left-right direction end of the image data of the first mark position of the right camera 210R is exceeded, so the PU 201 is connected to the memory M5. The count value Y in the middle is incremented by 1 (step S508), and the number of pixels b in the vertical direction of the camera loaded in the memory M9 and the number of pixels f in the vertical direction of the second registration mark in the memory M64 (steps S509, S510) The processing operations of steps S498 to S511 are repeated until the count value Y exceeds "b-f+1" in step S511.

The count value N exceeds the number f of pixels in the vertical direction of the second registration mark (YES in step S518), and the (X, Y) address of the image data of the a×b pixel in the memory M11 is determined to (X+e). The range of the address of -1, Y+f-1) includes the pixel data of the second registration mark of e × f in the memory M62. That is, it is determined that the image of the first mark position PM1 captured by the right camera 210R includes the second registration mark RM2 (RM2 _R1 ).

In addition, if the count value Y exceeds "b-f+1" (YES in step S511), the upper and lower ends of the image data of the first mark position of the right camera 210R are exceeded, and the CPU 201 determines that the right camera is in step S511. The image of the first mark position PM1 captured by 210R does not include the second registration mark RM2 (RM2 _R1 ), and the display 205 is erroneously displayed (step S512).

When the CPU 201 determines that the image of the first mark position PM1 captured by the right camera 210R includes the second registration mark RM2 _R1 (YES in step S518), the CPU 201 loads the count value X in the memory M6 at that time (step S519). The measurement position M2x1 _R in the X direction of the second registration mark RM2 _R1 is calculated from the count value X loaded, and is written in the address position in the X direction in the memory M70 (step S520). Further, the count value Y in the memory M5 at the time is loaded (step S521), and the measurement position M2y1 _R in the Y direction of the second registration mark RM2 _R1 is calculated from the loaded count value Y, and written in the memory.

The rotation speed VBp (VBp = VBr × 1 / η1 × 1 / η2) of the blanket cylinder during printing is added to the first position of the blanket cylinder in the vertical position PBM _R in step S345 (Fig. 41). The amount of deviation ΔY1 in the Y direction of the first registration mark and the deviation amount ΔY2 in the Y direction of the second registration mark at the first mark position determine the current vertical position PBM _R ' of the corrected blanket cylinder.
