The control circuit mainly includes a CPU 401 for controlling the operation of the copying machine main body. The CPU 401 includes a CPU 491 that controls movement of the scanner and adjustment of the lens position of the optical system 101, and
C that individually controls ON / OFF of each LED element of LED array 1040
PU492 is connected and these control while communicating with each other.

The CPU 401 has a ROM 402 and a battery backup.
The RAM 403, the parallel I / O 404, and the IC card I / F 481 are connected via a bus.

The ROM 402 stores a control program of the CPU 401, and the RAM 403 is used for working.

Also, signals from the respective key switches on the operation panel 400 and the respective sensors (sensors such as the reed switch 210 for detecting the positions of the levers 201 and 202) are input to the parallel I / O 404. . In addition, the operations of the motor, clutch, solenoid and the like in the copying machine are controlled via the parallel I / O 404. In addition, switching of the developing devices 3a and 3b
This is performed via the parallel I / O 404.

The IC card I / F 481 is an interface with an IC card inserted into the card set unit 480.

** Explanation of Simultaneous Mode ** (a) Outline of Simultaneous Mode Simultaneous (simultaneous multicolor) mode is an operation in which the operation timing and operation time of a plurality of developing units that store toners of different colors are imaged once. This is a mode in which an image is formed in a different color for each designated area on a single copy sheet by controlling each process.

For example, as shown in FIG. 3 as simultaneous mode displays 441a to 441d, the simultaneous mode that can be set in the copying machine includes a three-region division mode (mode C: 441c, mode D: 4).
41d) and two-region division mode (mode A: 441a, mode B: 44
1b), and each mode includes: Mode A (division into two areas): color black Mode B (division into two areas): black color Mode C (division into three areas): color black color Mode D (division into three areas) Divided): Defined as black color black.

That is, the image formed in the simultaneous mode is divided into regions having different development colors by a boundary line in a direction orthogonal to the scanning direction (the moving direction of the first moving body 215).

In order to form such a copied image, the operation timing of the developing units 3a and 3b must be controlled during one image forming process.

The timing control is performed by: i) loading the mode data from the IC card 600 based on the timing when the reed switch 210 is turned on when the first moving body 215 passes the position of the levers 201 and 202; In this case, the mode switching coordinates are registered together with the simultaneous mode in the data (FIG. 24; S13
63, refer to the simultaneous coordinate data (FIG. 15; S303 to S311, see later).

In the case of the above i), in the two-region division mode, ON of the reed switch 210 by the lever 202 is ignored.

(B) Regarding the levers 201 and 202 Next, a method of specifying the area division by the levers 201 and 202 and the mechanism of the timing detection will be described with reference to FIGS. 5 and 6. FIG.

As shown in FIG. 5, a guide groove 203 is formed between the original platen glass 16 and the operation panel 400 along the moving direction of the scanner (the horizontal direction in the figure). The lever 201, so that it can slide along
202 are installed.

By positioning such levers 201 and 202 on the extension of the boundary line of each area as shown in FIG.
16a is divided into three areas A, B, and C as shown.

 Here, the areas A, B, and C are as follows: Area A: Document first leading edge to first lever 201 Area B: First lever 201 to second lever 202 Area C: Second lever 202 to original trailing end

As described above, in the case of the two-region division mode,
The designation by the second lever arm 202 is invalidated.

As shown in FIG. 6, magnets 201a and 202a are integrally formed below the levers 201 and 202, respectively, and the time when the reed switch 210 passes through the positions of the magnets 201a and 202a. The reed switch 210
When turned ON, the signal is input to the CPU 401. Thereby, the above-described operation timing is calculated. In FIG. 6, b
Is the moving (scanning) direction of the first moving body 215.

(C) Operation Timing of Developing Unit FIG. 4 is an explanatory diagram of the relationship between the exposure position and the position of each developing unit.

As shown in FIG. 4, the original reflected light guided from the optical system is exposed to the exposure position W of the photosensitive drum 2 (in FIG. 2, the exposure position is not a position directly above, but is drawn slightly to the left. However, in FIG. 4, it is incident on the surface of the photosensitive drum 2 for easy explanation, and an electrostatic latent image is written on the surface of the photosensitive drum 2.

Now, the developing position of the developing device 3a (the position where the spike-shaped toner formed on the surface of the developing sleeve is transferred to the photosensitive drum 2) is "X1", and the developing position of the developing device 3b is "X1".
2 ", these two development positions are expressed as X1: angle α, time t _1. X2: angle α + β, time t ₁ + t _{2. With} respect to the light position W, respectively. . Note that the time t ₁ is an arbitrary point on the surface of the photosensitive drum 2 rotating at a predetermined speed.
It means the time required from the exposure position W to the development position X1. The time t ₂ is also the same.

FIGS. 9 and 10 show the first mode in the simultaneous mode.
9 is a time chart showing operation timings of the developing device 3a and the second developing device 3b. FIG. 9 shows a case using the levers 201 and 202, and FIG. 10 shows a case using the simultaneous coordinate data of the IC card 600. . FIG. 11 is a diagram for explaining a change in image density in the simultaneous mode, centering on a boundary portion of each region.

First, based on FIG. 9 and FIG.
The case where control is performed by 1, 202 will be described.

When the power of the copying machine is turned on, the solenoid of the first developing device 3a containing the color toner is turned on. As a result, the first developing device 3a is placed in a retracted state. Since the solenoid of the second developing device 3b containing the black toner is OFF, the second developing device 3b is located at the developable position.

In this state, it is assumed that the mode D (division into three areas: black color black) is set by the simul mode key 441. This is shown in FIG.
Is represented as ON.

Next, when the start of the copy operation is commanded by turning on the start key 445, the second edge is generated at the falling edge.
The motor of the developing device is turned on. This sets a state in which development with the black toner is possible (a state in which an electrostatic latent image formed on the surface of the photoconductor 2 can be developed).

After a predetermined time has elapsed since the start key 445 was turned on, exposure scanning of the developed image is started. Further, the development by the second developing device 3b is started after a lapse of t ₁ + t ₂ hours from the exposure start time of the front end of the developed image.

When the reed switch 210 reaches the position of the lever 201 by performing the exposure scanning, the reed switch 210 is turned on.

After the falling edge from t ₁ hour course of the reed switch 210, the first developing device 3a which houses a color toner
Is started. That is, the first developing device solenoid is turned off, and the motor of the first developing device is turned on. The development by the second developing device 3b is continued at this point.

Further, the time from the development start time of the first developing device 3a is
When t ₂ has elapsed, the developing operation by the second developing device 3b is stopped. That is, the solenoid of the second developing device 3b is turned on, and the motor is turned off. However, actually, in order to adjust the development density at the boundary part in consideration of the rise of the color image density and the fall of the black image density (see FIG. 11),
After elapse of t ₂ + t ₃ , the second developing device 3b is stopped. It will be described later t _3.

After a further time, the reed switch 210
When the lever reaches the position of the lever 202, the reed switch 210
Turns on again.

The principle of the timing control of the operation / stop of the developing device thereafter is substantially the same as described above.

That is, t ₁ from the falling edge of the reed switch 210
+ T _two hours after, the developing operation by the second developing device 3b is resumed.

Also, t ₁ from the falling edge of reed switch 210
(In fact, like the above, in order to adjust the development density of the boundary portion, t ₁ + t ₂₎ after a lapse of time, the color toner development is stopped by the first developing device 3a.

In the above, as shown in FIG. 11, the time t ₃ is set so that the image at the boundary can be completely reproduced in consideration of the fall and rise of the development density at the boundary. Is done.

Next, a case where the timing of the operation of each developing unit is controlled based on the simul coordinate data loaded from the IC card 600 will be described with reference to FIG.

That is, in FIG. 10, the control is performed not by turning on the reed switch 210 but by turning on / off the switching timer.

The set value of the switching timer is calculated based on the simul coordinate data (S1363: see FIG. 24).

** Description of Processing in CPU ** Hereinafter, the operation of the copying machine will be described in accordance with the processing in the CPU 401 and the like.

(A) Main Routine of CPU 401 FIG. 12 is a flowchart showing a main routine of processing in CPU 401 for controlling the operation of the copying machine.

The control CPU 401, for example, starts processing by turning on a power supply or the like, and then performs an initial setting in step S11.

Next, in step S13, an internal timer that defines the execution time of one routine is started.

Thereafter, an operation input process (S15), an IC card reading process (S17), a copy operation process (S19), and other processes other than the above (S21) are executed, and in step S23, the end of the internal timer is awaited. After that, the process returns to step S13, and the process is repeatedly executed.

Operation input processing (S15), IC card reading processing (S17),
The copy operation processing (S19) will be described below.

(B) Operation input processing (S15) FIG. 13 is a flowchart showing the operation input processing.

In step S101, the state of each key switch on the operation panel 400 is input.

As a result, any key switch is operated (S1
03; YES), and if the key processing flag is not set (S105; NO), the key processing flag is set (S10).
7).

Further, it is determined whether or not copying is being performed (S109). If copying is not being performed (S109; NO), a copy mode corresponding to the operated key switch is set (S111). If the key turned on is the start key 455 (S113; YES), the copying operation is started (S115).

If it is determined in step S109 that a copy operation is being performed (S109; YES), it is determined whether the operated key is the stop key 91. If the operated key is the stop key 91, the copy key is determined. The operation is interrupted (S121).

If no key switch has been operated in step S103 (S103; NO), the key processing flag is reset (S131), and the process returns to the main routine. Also, even if any key switch is operated (S103; YES), if the processing for the ON edge has already been executed (S105; YES), the process returns to the main routine.

(C) IC Card Reading Process (S17) FIG. 14 is a flowchart showing the IC card reading process.

In step S201, it is determined whether or not the IC card 600 is set in the copying machine.

(I) At the time of setting the IC card If the IC card 600 is set (S201; YES) and the copying operation is not being performed (S203; NO), the card insertion flag is determined at step S205.

As a result, if the card insertion flag is not set (S205; NO), it is checked whether or not the card is appropriate (S207). If the card is appropriate (S209; YES), the operation panel 40 is checked.
The card display 486 on 0 is turned on (S211). Further, a card insertion flag is set (S213), and "0" is substituted for the program number (S215).

Then, the contents of the substituted program No. are read out (S217), and provided that the contents have been registered (S219; N
O), the registered mode is set in the copying machine (S22).
1).

On the other hand, if it is determined in step S205 that the card insertion flag is set (S205; YES = the process at the time of card insertion has been completed), the operation waits for the operation of the load key 485 (S231). .

When the load key 485 is operated (S231; YES), the value of the program number is sequentially incremented for each operation (S233). When the value of the program number becomes “10” as a result of the increment (S235; YES), the value of the program number is reset to “0” (S237).

Thereafter, the contents of the corresponding program No. are read, and the read mode is set in the copying machine (S217).
To S221) are the same as when a card is inserted.

ii) When the IC card is not set In step S201, if it is determined that the IC card 600 is not set (S201; NO), or if the IC card 600 is set, the IC card is If the card is not a proper card (S209; NO), the card insertion flag is reset (S241), and the card display is turned off (S243).

(D) Copy Operation Process (S19) FIG. 15 is a flowchart showing the copy operation process.

In step S301, it is determined whether or not a copy operation is being performed. If the copy operation is being performed (S301; YES), it is further determined whether or not the simultaneous mode is set (S303).

As a result, if the simultaneous mode is set (S303; YES), it is determined whether or not the mode data loaded from the IC card 600 has registered therein coordinate data for giving a timing of switching the developing color. (S305).
The registration of the coordinate data in the IC card 600 is performed in step S1363 (FIG. 24) as described above.

If it is determined in step S305 that the coordinate data is registered (S305; YES), the timing of developing device switching is controlled by a timer based on the data, as shown in FIG. 10 (S307). ; YES.S311).

On the other hand, if the coordinate data is not registered (S30
5; NO), when passing through the lever 201 (and 202; in the three-split mode), the ninth
As shown in the figure, switching of the developing device is controlled (S309; Y
ES, S311).

Step S313 is a step which collectively shows the copy operation processing other than the above.

(E) Main Routine of CPU 492 FIG. 16 is a flowchart showing processing in the CPU 492 for controlling the LED array 1040.

The control CPU 492, for example, starts processing by turning on a power supply or the like, and then performs an initial setting in step S31.

In step S33, the process waits for a copy start. During the standby (S33; NO), when data for editing copy is transmitted from the CPU 401 (S45; YES), the data is set to L.
The data is converted into bitmap data for controlling ON / OFF of each LED element of the ED array 1040 (S47).

Further, when a copy operation start command from the CPU 401 is detected (S33; YES), it is determined whether or not the edit copy mode is set, and according to the result, the LED array 104 is determined.
Controls ON / OFF of each LED element of 0.

That is, when the edit copy mode is set (S35; YES), each LED element of the LED array 1040 is turned ON / OFF based on the bitmap data developed in step S47 (S37).

If the edit copy mode is not set (S35; NO), the LED array 1040 is used for normal inter-image erase (S41).

This copying machine is configured as described above, and is controlled as described above according to the mode input from the operation panel 400 or the mode loaded from the IC card 600.

〔The invention's effect〕

In the present invention, the operator sets the size reception mode, and the predetermined position where the size index (such as “A4 portrait” or “B5 landscape”) on the tablet is drawn is, for example, the upper left corner of the size. (In the size receiving mode, each predetermined position defines a corresponding size), and the size of the copying machine can be input by pressing any of the predetermined positions. That is, the copy paper size can be input by a simple operation, similarly to the case where the input is made by the key switch of the operation panel.

That is, the operator can easily recognize what size the size is actually, and what the setting direction is “vertical” or “horizontal”.
Even if the user does not know the size and the setting direction, the user can easily specify the copy paper size.
