FIG. 3 is a block diagram of the control section of the composite copying machine.

On-data such as a composite copy key 12, a trimming key 13, a masking key 14, etc. are input to the CPUI from the operation panel control section 5 via the I10 interface 4. The composite copy key 12 is operated when images of two original documents are to be copied onto a single paper surface. Further, the trimming key 13 instructs to turn on the blank lamp 23a so as not to copy the image on the outer periphery of the preset area. The masking key 13 instructs to turn on the blank lamp 23a so that the image within the set area is not copied. Note that the area is set by operating the numeric keypad 15 or the like.

The area set by operating the numeric keypad 15 etc. is RAM3.
is stored in the memory area M4. A ROM 2 connected to the CPU 1 stores a program that defines the operation of each device of the composite copying machine, and the CPU 1 transmits control data from the I10 interface 4 to the solenoid driver 7, blank lamp driver 6, etc. based on this program. Output. Based on this control data, the solenoid driver 7 controls the solenoids SQL 1 and 5QL2 to swing the flappers 59 and 60. The blank lamp driver 6 turns on the blank lamp 23a depending on whether trimming or masking is selected and the time and range depending on the set area. This memory area M4 constitutes the area storage means of the present invention, and the trimming key 13 and the masking key 14 are the same (mode selection means of the present invention).

FIG. 1 is a flowchart showing the operation of the composite copying machine.

When the composite copy key 12 is operated when inputting copy data and setting a mode, a flag F2 assigned to the memory area M3 of the RAM 3 is set (nl, n2).
- This flag F2 stores the state of whether composite copying has been selected or not, and is set when composite copying is selected. Next, a check is made to see if the masking key 14 has been operated, and if the masking key 14 has been operated, the R button is pressed.
Flag F1 assigned to memory area M2 of AM3
and perform masking mode processing (
n, 3-n5). Flag F1 stores the state a of whether trimming mode or masking mode is selected,
Sent when masking mode is selected. In the masking mode, control is performed to turn on a portion of the blank lamp 23a that corresponds to a region to be set later for a time corresponding to the region.

When the masking key 14 has not been operated, a check is made to see if the trimming key 13 has been operated. When the trimming key 13 is operated, the trimming mode is controlled (n8→n9). In this trimming mode, blank lamps 23a corresponding to portions other than the area to be set later are turned on for a predetermined period of time. Note that if neither the masking key 14 nor the trimming key 13 is operated, other processing is performed (n3→n8→n10).

When the operator inputs area data by operating the numeric keypad 15, this area data is stored in the memory area M41 of the RAM 3 (n6).

In this state, please wait for the print switch operation.)
Copying operation is started by operating the print switch. That is, the content of the flag F2 is checked to see if the composite copying operation is selected, and during the composite copying operation, paper is fed from the paper feed section 31, and solenoids SQL1 and 5QL2 are turned on. Furthermore, clear the contents of counter N (n11→n12 to n14)
. This counter N is allocated to the memory area M1 of the RAM 3, and counts the number of originals on which images are copied during the composite copying operation. Also, solenoid SQL
Since 1 and 5QL2 are turned on, the paper ejection section 37
The sub-transport path 62 and the intermediate tray 72 are open from the side, and the paper on which the image has been copied is stored in the intermediate tray 72.

Next, the document is fed, the contents of the counter N are incremented (n15), and the process of copying the set number of sheets is executed (n16, n17). All sheets on which images have been copied in this copying process are temporarily stored in the intermediate tray 72.

When the process of copying the set number of bones is completed, the contents of the counter N are checked (n 1 B). If the content of the counter N is not 2, the content of the flag F1 is checked, and if the flag F1 is in the cent state, the trimming mode is controlled (n19-=).

n20), if in the reset state, controls the masking mode (n19-"n21). Next, reads the area data stored in the memory area M4 n22),
The paper is fed from the intermediate tray 72, and the solenoids 5QL1 and 5QL2 are turned off to replace the original (n22 to n24→n15). In this way, the next original is fed from the intermediate tray 72, Since the solenoid SQL 1 is turned off, the paper that has completed the copying process is ejected to the outside. When this copying process is completed for the set number of copies, the contents of the counter N are checked, and if the contents are 2 at this time, the start of the next copying operation is waited (n18-nl). Note that if the flag F2 is in the reset state after the print switch is operated, other processing is performed (n25).

In the above, n3 to n5. n8. n9. n13. n19
-n21 and n24 correspond to mode changing means of the present invention. In this way, when the masking mode is selected, the masking mode is performed in the copying process for the first original, and the trimming mode is performed for the second original. Conversely, if the trimming mode is selected, the trimming mode is performed during the copying process for the first original, and the masking mode is performed during the copying process for the second original. For example, using the manuscript shown in Figure 4 and (B),
), the trimming key 13 is operated after setting the area aw d for the first document shown in the figure. As a result, only the image in the area a to d of the original shown in the figure is formed on the paper. After this, the masking mode is performed on the second document shown in FIG. 10(B), and an image in a range other than the area a"-d is formed on the same sheet of paper. As a result, as shown in FIG. You can get the image.

(11) Effects of the Invention According to the present invention, whether the trimming mode or the masking mode is selected for the previous original is stored in the mode storage means, and the set area is stored in the area storage means. 0 During composite copying work, the paper is guided to the copying process unit twice by the circulating conveyance means, and during the first copying process, the mode stored in the mode storage means is set for the range stored in the area storage means. The mode which is not stored in the mode storage means can be executed for the range stored in the area storage means during the second copying process. As a result, the trimming mode and the masking mode can be performed on the same image area for the images of two original documents, and both images can be constructed as one. At this time, it is only necessary to input the setting area and select the mode once, and once the copying operation is started, there is no need to manually move the paper, and the composite copying work can be easily performed.
