The overall operation in this complex configuration will be briefly explained using the flowchart shown in FIG. Now BTEP15
When the power switch 21 is turned on at 5GC, power is supplied from the power supply circuit 85 to each part. With this, 8TE
Initial reset circuit 8 as shown in pJsr
7 works.

As a result, my credit score is 6, Su9 J Ha5TEP 159
The initial state 111 is set in . The microprocessor 91 receives the clock signal from the oscillator 89.

The microcontroller 6, 91 executes the commands one by one using the pulses, and first raises the output through the output interface circuit 119 in step 161. The temperature of the fixing device 135 is detected by the fixing temperature detection device 113, and the detection signal is input to the microprocessor 91 via the input interface circuit 103. At this point, the microprocessor 91' determines whether the detected temperature has reached the fixing temperature at 8TEP I g J. As a result, if the detected temperature reaches the fixing temperature, step 165 lights up the copy ready 27 flag 23 through the output interface circuit 119, thereby changing to the copy ready state 111 and displaying the number 9. In step 161, operations on the double meric key s1, the copy key, etc. are enabled. On the other hand, if the detected temperature has not reached the fixing temperature of 1 degree, the process returns to step 161 and the fixing device 135 heats the heater again. Further, when the copy key 29 is turned on in the accepting state, the microprocessor 91 receives the signal and the expansion drive device 12
1. Operate the cassette selection device 129, paper feed device 131, etc. This is it, System! At 111, paper is supplied from first and second copy paper cassettes 17119 and is transported by a transport path. When the paper detection device 11 detects that the transported paper has reached a predetermined position, the microprocessor 91 receives the signal and in step 173, the automatic document feeder 5, the optical system moving device 123, and the exposure control device 125, operating the charging device 127; That is, first, a document is fed by the automatic document feeder 5, and at this time, a detection signal from the document detection device 109 is read by the microprocessor 91 via the input interface circuit 103, and the microprocessor 91 determines whether or not the document is fed. When it is determined that the optical movement device 1
23, the exposure control device 125 and the charging device 127 operate to start exposing the photosensitive drum. Thereafter, well-known development, transfer, and fixing cycles are sequentially executed. At this time, when the transferred paper is conveyed to the fixing device 136, the paper detection device 11 outputs a paper discharge signal, which is input to the microprocessor 91 via the signal line input interface circuit 103. Then the microprocessor 91
In step 115, data in the user memory area 153 of the RAM IJ 9 is referred to, and in step 119, the paper output destination is specified to the sorter control device 131. However, if the data does not exist in the user memory area 153 at this time, the processing is entrusted to the Ji-tance control of the sorter control device 137/ in step 181. Thereafter, the process returns to step 163 and the same procedure is repeated.

Next, a detailed explanation will be given of the means by which the groggle grading using the RAM 139, which is a feature of the present invention, is utilized in an electronic copying machine. According to the present invention, the copying machine can be set to key counter operation using the magnification mode P selection switch 11'/, so that the copying operation will not start unless the user inputs a unique code. This will be explained below with reference to the flowchart shown in FIG. First, in step 183, it is determined whether the mode selection switch 111 has selected the key counter operation.

If key counter operation is not selected, step 18
Returning to step 3, the key code 55 is selected and the process proceeds to step 185, where it is determined whether or not the key code 55 is set.Next, in step 187, the 4-digit key code Checks whether or not has been input. If not, returns to step 183; if it has, returns to step 18#.
At this point, the key code is displayed on the data display 49.

Next, in step 191, it is checked whether the memory switch 53 is turned on. If the memory switch 53 is not turned on, step 191 is performed.

Return to program 181, turn on the microlog,
Su91 is ST, key code in at Gu J51j! ,
Tosui, clear Chi 55 and get RA in step 195
The key code stored in advance in the key code area 149 of M 13 # and the content displayed on the display 49 are compared.

If they do not match as a result of the comparison, the process returns to step 183; if they match, step 197 clears the display contents of the data display 49 while keeping the key code secret. And the microprocessor, Su91 is Stella f1991
/C, the copying machine is set to a state ready for copying operation. Then, in step 201, it is possible to accept the Niemeri cookie 31 tocobi switch 29. If the copy switch 29 is pressed at this time, suppression of the copy switch 29 is detected at step fz o H, and step XO
A copying operation is performed at S. On the other hand, Step 203
If it is determined in step 207 that the copy switch 29 has not been pressed, the mode selection switch is selected in step 207.

Check whether key counter operation is selected in key 111. If the key counter operation is selected, the correction key 33 is pressed in step 209 to check whether the user is a friend.In this embodiment, if the key counter operation is to be returned to its initial state, the correction key 33 is turned on It is done by doing. If the correction key 33 is not pressed, the process returns to step 183, and if the correction←33 is not pressed, step 211 prohibits reception of the second merrick key 31 and copy switch 29, and turns off the copy permission rung 7s. do. Then, in step 213, the microprocessor 91 uses the key code to calculate the number of required sheets of paper that have been used so far, and calculates the number of sheets of paper that have been used so far,
Key code area 149 of RAM 139 corresponds to
write to. As a result, until a new key code is input, the copy permission rung 73 remains in the off state, and no operation of the copy key 29 is accepted.

By setting the mode selection switch 117 to the normal copy mode, the operation of the copy key 29 is enabled as long as the copy permission rung 73 is lit. As shown in FIG. 5, this mode selection switch 117Fi generates a 3-bit binary code, and five control modes of the copying machine can be selected using the binary code. In FIG. 5, when the ``1'' mode is selected, a binary code of @000m is generated and the normal copy mode is entered. This normal copying mode is a mode in which the above-mentioned normal copying operation is performed. When the mode 12' is selected, a pinary code of "001" is generated and the key counter mode is entered.The key counter mode is a mode in which the 9-key counter operation is performed as described above.Moreover, the mode 131 is selected. When the binary code of ``010'' is generated and the RAM read mode ■ selects the 14# mode, the binary code of ``011.'' is generated and the RAM read mode ■ is further selected as @51 mode. The binary code "ioo" is issued, and the RAM write mode is selected respectively.
Read mode ■ and RAM write mode are RAM I J
Each area 143 other than the user memory area 150 of 9
Read and write mode for 151 to 151, RA
The M read mode (2) is a mode for successive reading only to the user memory area 150.

Next, the user writes program 2 (
The procedure for writing (copy conditions) will be explained with reference to FIG. When the mode selection switch 117 is set to the normal copy mode or the key counter mode, the user of the copying machine can write a desired program and execute the program. However, in the case of normal copy mode, from the time the power switch 27 is turned on,
Also, in the key counter mode, each log message can be written from the time the key code is accepted. First, in step 215, it is determined whether or not it is a key color/removal operation, and if it is a key counter operation, further step 2 is performed.
Check whether the key code has been input in step 11,
I will If the key code is input, and if the normal copy mode is selected, a check is made in step 219 to see if the write switch 5 has been turned on. When the write switch 5I is turned on, the contents of the program (copy conditions) are entered from the ten key 3 in the step 221.

The input contents are displayed on the data display 49 in step 223.In step 225, it is checked whether the memory switch 53 is turned on.
When the memory switch 53 is turned on, the microprocessor 91 in step 231 writes the contents displayed on the display 49 into the user memory area XSS of the Oboro '139.

Next, in step zssk, the manual input of the command code F is accepted, and in step 235, the said command code is displayed, and when it is determined that the memory switch 53 is turned on in step z, 5vyc, the said command code is inputted in step 239. The code is written to the second memory, area 153. In this case, each glodarum consists of a maximum three-digit copy number expressed in decimal numbers and a four-digit decimal instruction code.

Further, when the write switch 51 is turned on in the step 247, the steps 221, 223, 2, 5, 211, 23
3,235,131,239 are repeated to write another program. On the other hand, if the number of copies is entered incorrectly and the key is pressed manually, it is determined by the correction key 31 that the correction key 3S has been turned on, and in step 229 the display contents of the data display 49 are reset, and the process returns to step 221. As a result, it becomes possible to key in the number of copies again. Similarly, when the instruction code is keyed in by mistake, pressing the correction key 33 will confirm that the correction key S3 has been turned on at step 24.
In 5, it is determined that ste is determined, and in g z4v', r-ta e
The contents displayed on the indicator 49 are cleared, and the process returns to step 233, allowing the instruction code to be keyed in again. Note that the number of copies is the content displayed on the number of copies display 39. This display 39 indicates how many copies of the set number of copies have been completed, and is counted at the time the paper is fed. However, before the paper is supplied, that is, at the stage of supplying selection information to the cassette selection device 129, the next copy, that is, the display content of the copy number display 39 at that time, is changed to "
11, the command for the number of copies has already been executed.

Furthermore, a glogram name code can be added to the above-mentioned lrodallum. That is, in the flowchart shown in FIG. 12, the key code input switch 5 is
Step 5 is turned on, and the memory switch 53 is turned on in step 251.Next, in step 253, the program name code and start address are input. Then, if you turn on the write switch 51, Stella! At 255, it is detected whether the write switch 61 is in the on state. As a result, in step 257, the program name code is written to the program name code dedicated storage area of the user memory 97153. Then, in step 259, the key code input switch 55, memory switch 5S, and write switch 51 are cleared.

On the other hand, the program is read by inputting the program name code using the Niemeric key 31 and the key code input switch 55. That is, in the flowchart shown in FIG.
It is checked in step 261 whether the key code input switch 55 is on or not. If the key code input switch 55 is on, the next step 263 accepts input of a program name code from the niche key 31. Furthermore, step 2
65tf: Key code input switch 5, where it is checked whether the key code input key and +55 are continuously turned on during the program name code input.
If 5 is on continuously, next step: l61
Check whether the program name code input in V'C is in the program name code exclusive area, and if there is a program name code input in the program name code exclusive area IIi, <In step 269, check the start address of the program. Read out.

Next, Ste! Check whether the copy key 29 is turned on in 2rl and turn it on, dste!
2731C. To stop the Df program, either turn on the correction key 33 or reach the set number of copies.

The program answers set by the user are, for example, multiple types of copy conditions corresponding to multiple sheets of originals. This includes specifying the ejection light.

Note that when a copying operation is performed while a program is being executed, the instruction code to be executed in the next copying cycle is displayed on the data display 4911C.

Next, the state of writing a program into the user memory area 153 of the RAM Jsy will be explained with reference to FIG. The user memory area 153 is composed of a program area 215 and a program address area 211. The program area 276 can store a plurality of programs, and one program is stored between the glogram star F code xvs and the program end code 281.

In other words, as mentioned above, the number of copies XaS and the instruction code 2
#5 constitutes one instruction system, and this instruction system collects together to constitute one program.
79 and the end code 281. In the program address area 277, each program name code P281 and the start address of that program (address where the start code is stored) 289 are arranged in a pair IK.
are stored correspondingly. This program address area 277
Each address (), ノ+1. J+3) is determined in advance, and in order to call a desired program, the program name is searched from the program address area 277 and the start address 289 of the program is specified.

The program is written in this state,
An example of the writing procedure is shown in Figure 7.8For example, when making b copies on A4 paper size, the number of copies (h)'
z 9J and A4 size selection command code) When copying one sheet with secondary KB5 paper size to write P293, number of copies (s) x s s and B5 size selection command code 297
AD about copying j copies at 0th order! or 5DIP
When specifying the number of copies (j) z s y and ADF
Or write the SDF specification instruction code 301. Next, if the same document is to be copied twice, SOS (to the number of copies) and the twice copy command code SOS are written in the number of copies.

Finally, when specifying the sorter ejection light for one copy, write the number of copies (As or r) and the sorter ejection light specification command code SOS. must be in the order in which the instruction codes are written.

In this manner, a desired program is written into the user memory area 153 of the RAM IJ9.

Next, regarding the control of the microprocessor 91 that is configured as described above and executes the nine programs, the microprocessor 70 shown in FIG.
-Explain with reference to Tayat. In step 311, the start address of the program is stored in the working register WR99. Next, in step 313, the counter q is automatically reset to ``Om''.Then, in step 315, the access logical address is calculated from the start address given and the contents of the counter q.Initially, the counter qO is 101. Therefore!I+1
The address is calculated as address p. The primary stage is incremented by 2 addresses and always calculates the address where the number of copies is stored.
In llC, check whether the contents of address p is an end code.If it is not an end code, then step! 319
The contents of the address p are displayed one after another at the set number of sheets display 31.
Set to . Then, in step 321, the content of address p+1, that is, the instruction code, is read out and decoded, and based on the result, copying conditions are set in the external device via the output twin of the microprocessor 91.

Then, at step JJJ', the contents of counter q are set to 1.
Increment by 0 Step 5 Check whether the content of the set number display 37 is zero at step 5zsyc, and if it is not zero, copy operation is performed at step 327 and step 3
At step 29, the contents of the set number of sheets display S1 are subtracted by 1, and the process returns to step 325, where the copying operation is repeated until the contents of the set number of sheets display 37 becomes zero. When the content of the set number display J1 becomes zero, the program returns to Stella f315, the address p is calculated again, and the program 2 process is performed in the same manner.

An example of actual execution of the log system shown in FIG. 7 is shown in FIG. 8. In other words, the first h sheets are A4 size paper, the next one is B5 size paper, the next j sheets are made using SDF, the next two sheets are each made by copying the original twice, and the last one is made using a sorter. Each copying operation is performed so that the paper is ejected to the designated tray.

On the other hand, when the power is turned on or the key code is activated, copy it! After a series of copies such as log 2 copy, continuous copy, and single copy are completed, the state becomes the initial state at the 9th point in time. In this initial state, the paper size is A4, the document feed tray is 13, the number of copies is 1 each, and the paper feed destination of the sorter is in the order of the trays of the sorter, that is, in the order of 1 to 11.
The second ejection tray 11 is used for the ejection light of the original.

The above-mentioned initial state is set when a copying operation is not performed for a certain period of time or more even if there is another designation by a switch on the operation panel or an instruction code.

Note that when interrupting copying during a copying operation based on the copying conditions, the ADF is temporarily stopped and the original to be interrupted is fed to the SDF and discharged onto the tray 1). It is also possible to discharge the copied sheets to an unused section of the sorter. If there is no unused portion, the sheet is discharged to the first sorter.

As detailed above, according to the present invention, different copying conditions are set in advance for each number of copies and stored in the storage means, and each time a desired number of copies is reached, the preset copying conditions are transferred from the storage means. For example, when performing continuous automatic copying of a number of originals by reading the originals and sequentially executing the copying operation, it is possible to select copying conditions for each original and automatically specify the copying conditions. A copying machine control device that can significantly improve efficiency can be provided.
