Next, the operation of the above embodiment will be described with reference to the flow charts shown in FIGS. In step S1 of FIG. 7, initial setting is performed. Here, for example, the memory 71 is initialized. At step S2, the film 7 on which the identification code 10 is recorded is inserted into the insertion opening 8
It is determined from the output of the film detection sensor 23 whether or not it has been inserted into the. Wait until the film 7 is inserted, and if it is determined that the film 7 is inserted, the process proceeds to step S3. In step S3, the carry motor 16 is rotationally driven. As a result, the film 7 is conveyed in the reverse x direction and enters the inside of the apparatus. In step S4, it waits for the leading edge detection sensor 24 to detect the leading edge of the film 7. Film 7
When the tip of is detected, the process proceeds to step S5. In step S5, the counter 72 is cleared and the encoder 16a
The counting of the pulses output from is started.

In step S6, the bar code reader 25 reads the identification code 10 recorded on the edge of the film 7. In step S7, the read identification code 1
Based on 0, the count values of the cutting position and punch position of the film 7 are calculated and stored in the memory 71. When the film 7 shown in FIG. 2 is conveyed here, there are two sets of a document set with simultaneous output of four colors and a document set with simultaneous output of two colors.
The data for one original set is recorded.

For example, as shown in FIG. 12, the length of the film 7 in the x direction is "580", the distance from the tip detection sensor 24 to the disc blade 30 of the Y cutter 3 is "200", and X is X. The distance to the knife 40 of the cutter 4 is "600", and the distance to the punch 50 is "10".
00 ". When the punched holes 11 are formed at the position of the distance "20" from the end of the film, respectively, K _P1 = 1000 + 20 = 1020 K _P2 = 1000 + 180 + 20 = 1200 K _P3 = 1000 + 360 + 20 = 1380 is calculated. Here, the cutting in the x and y directions is carried out while the film 7 is once carried into the inside of the apparatus and punch holes are formed, and then the film 7 is conveyed from the back side of the apparatus to the insertion port 8 side. Therefore, as the count value indicating the cutting start position of the X cutter 4, K _Xs1 = 600 + 580 = 1180 (the rear end of the film 7 is at the position of the knife 40) K _XS2 = 600 + 180 = 780 (the position x of the film 7 x
₍₁ is in the position of the knife 40) is calculated. Further, K _XE = 600 + 0 = 600 (a state in which the leading edge of the film 7 is at the position of the knife 40) is calculated as a count value indicating the cutting end position of the X cutter 4. Further, as a count value indicating the cutting position of the Y cutter 3, K _Y1 = 200 + 540 = 740 (position x _{2 of the} film 7
Is in the position of the disc blade 30) K _Y2 = 200 + 360 = 560 (the position x _{2 of the} film 7 is in the position of the disc blade 30) K _Y3 = 200 + 180 = 380 (the position x _{1 of the} film 7)
Is in the position of the disk blade 30).

The x-coordinate of the cutting position of the film 7 is previously recorded in the identification code 10 by the simultaneous output of two colors and the simultaneous output of four colors as described above. Step S8
Then, based on the count value indicating the punch position obtained by the calculation, the punch mechanism 5 punches holes 11 in the film 7.
Open. When all punching is completed, step S9
Move to. In step S9, the switching claw 17 is moved to the position shown in FIG.
At, turn in the counterclockwise direction and switch to the position indicated by the chain double-dashed line. As a result, the transport path is switched to the storage section 6 side. In step S10, the motor 16 is rotated in the reverse direction to convey the film 7 in the x direction. In step S11, the film 7 is cut by the X cutter 4 and the Y cutter 3 and discharged to the storage unit 6, and is discharged to the tray unit 61 in document set units.

In the punching operation of step S8, the count value of the counter 72 reaches K _P in step S21 of FIG.
Wait for the film 7 to reach the punching position.
When the film 7 reaches the punch position, the process proceeds to step S22. In step S22, the motor 16 is stopped. In step S23, fine adjustment processing for positioning the film 7 in units of 10 μm is performed. Step S24
Then, after fine adjustment, the punches 50 and 51 are lowered to open punch holes. At this time, both punches 50 and 51 are lowered in the case of simultaneous output of four colors, and only punch 50 is lowered in the case of simultaneous output of two colors or output of only one color.

In step S25, the punches 50 and 51 are waited for ascending. This determination is made by the outputs of the sensors 59a and 59b. In step S26, it is determined whether or not all punch holes have been opened. This judgment is made based on whether or not the punching operation has been completed for all the calculated count values K _p . If all punch holes have not been processed, the process proceeds to step S26, the motor 16 is rotated in the normal direction, the film 7 is re-conveyed, and the process returns to step S21. If it is determined that all punching is completed, step S25
To step S27. In step S27,
It is determined whether the trailing edge detection sensor 26 has detected the trailing edge of the film 7. If not detected, step S28
, The motor 16 is rotated in the normal direction for a predetermined time, and then the process returns to step S27. The trailing edge of the film 7 is the trailing edge detection sensor 2
Step S27 and step S28 are repeatedly executed until 6 is detected, and when the trailing edge passage is detected, the process returns to the main routine.

Here, since punching is performed before cutting, the positional accuracy of punch holes is higher than in the case where punching is performed after cutting, and the registration of each color separation plate can be performed accurately. In the fine adjustment process of step S23, the output of the reference position sensor 27 is read in step S31 of FIG. Here, the reference position sensor 27 includes a light emitting element and a light receiving element having a light receiving surface divided into four, and whether or not the reference position mark 28 (FIG. 2) formed on the film 7 is located at the center of the light receiving surface. Can be detected. Step S3
At 2, it is determined whether the reference position mark 28 is detected. If it is determined that the reference position mark 28 is not detected, the process proceeds to step S33. In step S33, the motor 16 is normally rotated to move the film 7 by 100 μm, and the process returns to step S31. Here, it is moved to a rough punch position by the count value of the counter 72, and is roughly driven in 100 μm units until the reference position mark 28 is detected.

If it is determined in step S32 that the reference position mark 28 is detected, the process proceeds to step S34. In step S34, the output of the sensor 27 is read again. In step S35, it is determined from the outputs from the four light receiving surfaces whether or not the reference position mark 28 is located at the center of the light receiving surfaces. When it is determined that the reference position mark 28 is not located at the center of the light receiving surface, the process proceeds to step S36. In step S36, the motor 16 is driven to move the film 7 to 10
It is moved in μm units and the process returns to step S34. Step S
If it is determined at 35 that the reference position mark 28 is located at the center of the light receiving surface, it means that the reference position mark 28 has been accurately positioned at the punch position, and the process returns to the punch operation subroutine.

Here, positioning in units of 10 μm is possible
As a result, each disassembled version can be accurately registered. Figure 7

When the operation of step S44 or step S45 is completed, or when it is determined that the _count value is not K _XS in step S41, the process proceeds to step S48. In step S48, it is determined whether or not the _count value has reached K _XE , that is, whether or not the cutting end position of the film 7 in the x direction has been reached. If it is determined that the arrival has been reached, the process proceeds to step S49. In step S49, the motor 16 is stopped, the transport of the film 7 is temporarily stopped, and then step S50 is performed.
Move to. In step S50, it is determined whether two-color simultaneous output or four-color simultaneous output is performed as in step S43.
If it is determined that two colors are output simultaneously, the process proceeds to step S51.
In step S51, the motor 43 is reversed and the knife 42 is raised. If it is judged that four colors are output simultaneously, step S
Move to 52. In step S52, the motors 43 and 44 are
Is reversed and the knives 42, 40 and 41 are raised.

When the processing in step S51 or step S52 is completed, or when it is determined in step S48 that the count value is not K _XE , step S in FIG.
Move to 61. In step S61, whether or not the count value of the counter 72 has reached K _Y , that is, the film 7 is y
It is determined whether the cutting position in the direction has been reached. If it is determined that it has been reached, the process proceeds to step S62. Step S6
In 2, the motor 16 is stopped to stop the transport of the film 7 and the process proceeds to step S63. In step S63,
Lower the disc blade 30 and then move the disc blade 30 to y.
In the y-direction to perform cutting processing in the y-direction. When the cutting in the y direction is completed, the disc blade 30 is raised to return to the original position and the process proceeds to step S64.

In step S64, the clutch 74 is turned off so that the rotational force of the motor 16 is not transmitted to the rollers 13-15. As a result, the rotational driving force of the motor 16 is transmitted only to the first roller 12. In step S65, the motor 16 is reversely rotated to start the transport of the film 7. When the transport motor 16 is driven in this state, only the film separated in step S63 is transported in the x direction and discharged to the bin 62 in the tray portion 61. In step S66, it is determined whether a predetermined time has elapsed. This predetermined time is sufficient for the film to be carried out to the bin 62. In step S67, the carry motor 16 is stopped. In step S68, the clutch 74 is turned on. Note that step S
In 64 to 68, even if the conveyance motor 16 rotates while the drive of the rollers 13 to 15 is cut off, the counter 72
The counting operation by is prohibited.

In step S69, it is determined whether or not all the discharges of one original set have been completed. When it is determined that the delivery of all the cut films in one original set is completed, the process proceeds to step S70. In step S70, the tray portion 61 is moved to the left side in FIG. 3 by one bin. When it is determined in step S69 that the cutting of the film 7 is not completed in one original set, when the movement of the bin 62 is completed in step S70, or FIG.
When it is determined that the film 7 has not reached the cutting position in the y direction in step S61 of 0, the process proceeds to step S46.

In step S46, the motor 16 is rotated in the reverse direction to convey the film 7 in the x direction. In step S47, it is determined whether the cutting in the x direction is completed. The determination of this end is made based on whether or not the processing with the last count value stored in the memory 71 has been completed. If not completed, the process returns to step S41, and if completed, the process shown in FIG.
Return to the main routine of.

Since the cutting operation is performed by reading the identification code 10 recorded on the film 7, it is possible to prevent a cutting error.
