In addition, referring to FIG. 1, at the end position of the 7-segment display portion 9, each display of "m / m" and "%" is individually lighted. Further, there is a print button 11 for instructing copy start.

Next, the main routine of the copy process in the variable magnification copying machine according to the present invention will be described with reference to FIG.

When the power is turned on, "CPU initialization" in the main control unit 1 is performed by the process of step. That is, the RAM in the CPU is cleared and the conditions are set.

Next, the process goes to the "dimension scaling input" subroutine. Details of the steps are shown in FIG.

Next, the process goes to the "numeric key reception" subroutine of step. Details of the steps are shown in FIG.

Next, go to the "7SEG display" subroutine of step. Details of the steps are shown in FIG.

Next, it goes to the "other control" subroutine of the step. In this step, in addition to various controls for performing a predetermined variable magnification function, fixing temperature control, exposure lamp control, scanner control, paper feed conveyance control, various controls around the photosensitive drum, and other key reception in the operation unit 2 Etc. are performed, a copy is performed on a desired sheet at a specified scaling ratio, and the cycle of returning to the step before the step is repeated.

Therefore, during the processing of the step, there is a print button on / off determination step, and the copy process proceeds by turning on the print button.

Hereinafter, the contents of each of the above subroutines will be described in order.

When the power is turned on, the process goes through the steps in FIG. Then, in FIG. 3, first, the step "WT mode check" is reached. Here, it is determined whether or not the key is in a mode in which the key can be accepted. If the mode is not the acceptance mode, the process proceeds to the steps of FIGS. 2 and 5, and if it is the acceptance mode, the dimension scaling key 6 is checked in the step. Here, it is checked whether or not the size scaling key 6 is turned on. If it is not turned on, the process proceeds to the step. If it is turned on, the document size display section 7 is turned on via step ,, and the next cycle is performed via RET. Go to the document size display check.

In this step, it is checked whether or not the document size display section 7 is on. If it is on, the document size display section 7 is checked in step.
Turn off. If it is not on, go to the step. In the step, it is checked whether or not the copy size display portion 8 is turned on. If it is turned on, the process goes to the step. If not, the process goes to the step.

In this step, the document size display section 7 is turned on to set the size change acceptance mode, the contents of DBORG (original size data buffer) are reset, and the "%" display on the 7-segment display section 9 is turned off. After turning on the "m / m" display, go to the step.

After going through the steps, go to the steps. In the step, check whether DBORG is zero, and if it is zero, turn on the "%" display in step 1 and turn off the "m / m" display at the same time, reset the dimension scaling acceptance mode, and then go to the step. .

If DBORG is not zero in step, go to step 11. In step 11, the copy size display section 8 is turned on, the contents of DBCOPY (copy size data buffer) are reset, and the process proceeds to step.

In step, the copy size display portion 8 is turned off and the process goes to step. In step, it is checked whether the content of DBCOPY is zero, and if it is zero, go to step.
If it is not zero, the contents of DBCOPY are divided by the contents of DBORG in the step, 100 times that is stored in DBRED (magnification data buffer), and the process proceeds to the step.

In FIG. 5, in the subroutine of the step of accepting the ten-key pad, the procedure first goes to the step.

In the step, it is checked whether or not the key acceptance mode is the WT mode. If it is not the WT mode, the process goes to the step, and if it is the WT mode, the process goes to the step.

In the step, it is checked whether or not the “0” key in the numeric keypad 5 is turned on.
If on, go to step.

In the step, it is checked whether or not the "1" key in the numeric keypad 5 is on, and if it is on, go to the step,
If it is not on, it is the same as the "0" and "1" keys.
Check and process the "8" key, and go to the step.

In the step, it is checked whether or not the "9" key is turned on, and if it is not turned on, the process proceeds to the step (see FIG. 4). If it is on, go to the step. At step S9, "9" is stored in A (data buffer) and the process goes to step S6.

At the step, "zero" is stored in A and the process proceeds to the step. At the step, "1" is stored in A and the process goes to the step. In step, it is checked whether or not the document size display portion 7 is turned on. If it is turned on, the process goes to step, and if not, the process goes to step. In step, it is checked whether or not the copy size display section is on. If it is on, the process proceeds to step. If it is not on, the process proceeds to step. In the step, the set number processing relating to the key reception of the number of copies in the normal copy mode other than the variable magnification mode is performed, and the process proceeds to step (see FIG. 4).

In the step, it is checked whether or not the first digit of the contents of DBCOPY has been entered. If it has been entered, go to the step. If it has not been entered, go to the step.

In step, enter the contents of A in the first digit of DBCOPY and go to step. In the step, it is checked whether the second digit of the contents of DBCOPY has been entered. If it has been entered, go to the step. If it has not been entered, go to the step.

In the step, enter the contents of A in the second digit of DBCOPY and go to the step. In the step, it is checked whether or not the third digit of the contents of DBCOPY has been input. If it has been input, go to step (see FIG. 4), and if it has not been input, go to step.

In step, enter the contents of A in the third digit of DBCOPY and go to step (see Fig. 4).

In the subroutine of the step for performing 7SEG display in FIG. 4, it is checked in step whether or not the document size display section 7 is on. If it is on, the procedure goes to step, and if not, the procedure goes to step.

In step, it is checked whether or not the copy size display section 8 is on. If it is on, the process proceeds to step, and if not, the process proceeds to step. In the step, the contents of DBRED (magnification data buffer) are stored in A and the process proceeds to the step.

At the step, the contents of DBCOPY are stored in A, and the process goes to the step. In step, store the contents of DBORG in A and go to step. At the step, the contents of A are stored in 7SEG and displayed on the 7-segment display section 9, and the process goes to step (see FIG. 2).

In step, the other control described above is performed and the process returns to step.

By programming the algorithm shown in FIGS. 2 to 4 in the main control unit 1 shown in FIG. 5, the scaling factor can be designated by the following procedure.

(1) By pressing the dimension scaling key 6, the dimension scaling accepting mode is set, and at the same time, the document dimension display section 7 indicating the input of the document dimension is turned on.

(2) The size of the original is input to the main controller 1 using the ten keys 5. Along with this, the document size is displayed on the 7-segment display unit 9 together with the character "mm".

(3) By pressing the size scaling key 6, the main control unit 1 is switched to a state in which the desired copy size input can be accepted,
At the same time, the copy size display section 8 indicating the waiting for input of the desired copy size is turned on.

(4) Input a desired copy size to the main controller 1 using the ten keys 5. Along with this, the designated copy size is displayed on the 7-segment display section 9 together with the character "mm".

(5) When the size scaling key 6 is pressed, the scaling ratio is calculated from the previously input original size and copy size, and the value is displayed on the 7-segment display section 9 together with the character "%".

At that time, although not shown in the flow chart,
When the ratio is less than 50% or 200% or more, the variable scale display is 50.
It would be convenient to blink as% or 200% to call attention.

In this way, when the designation of the scaling factor is completed, the print button (see FIG. 1) is pressed to execute the copy process at the designated scaling factor.

To reset the size change acceptance mode, the size change key 6 may be pressed with the original size input “0” or the copy size input “0”.

(Effect) According to the present invention, a single key can be used for a plurality of functions, so that the number of keys can be reduced as much as possible to improve space efficiency and operability, which is advantageous.
