A 3-digit PIN number of 0 is stored. Address “9A03
~9A14" stores data on the number of copies executed by the electronic copying machine 10. Address "9AO3~
9A05°1 stores data on the total number of copies, and addresses '9A06 to 9A14' store data on the number of copies for each size by 3 hides. Addresses '9A15 to 9A28'9 store: Data for one copy unit price for each size is stored in 4-byte units.

The copy unit price for each paper size can be set up to a maximum of 4 digits of 99.99 yen, and one digit is stored in correspondence with one byte. Addresses “9A29 to 9A3C” contain multiple ICs.
Data regarding the total number of copies that have been made with the card 110, the number of copies for each paper size, and the number of copies that have been made with the IC card 116 are stored.

As shown in FIG. 7B, the addresses '8AOO to 8BA3' of the RAM 140 built into the IC card 116 contain the data of the passwords of 20 electronic copying machines, and
Data on the number of copies for each electronic copying machine is stored.

That is, one IC card 116 can be used to use 20 electronic copying machines 10 with different passwords registered.

In this case, for example, the address "9A0" shown in FIG.
If the PIN data stored in addresses 0 to 9A02" match the PIN data stored in addresses 8B7A to 887C, then the IC card 116
This means that 19 usable electronic copying machines 10 have been registered. Each time copying is executed, data at addresses "9A03-9A14" of the RAM 124 is transferred and stored at addresses "8B?D-8B8E"'.

Next, referring to FIG. 4, the operation or operation of the electronic copying machine 10 in the copy mode will be described based on the flowchart shown in FIG.

In FIG. 8, in the first step Sll, it is determined whether the IC card 116 is attached to the card receiving section 118. That is, the MPU 120 is an IC
When the card 116 is installed in the card receiving part 118, the connectors 136 and 138 are connected, and the RAM 14
0 is read directly through the Hass line to MPU 120. If the attachment of the IC car 1116 is not confirmed, the card attachment indicator 112j lights up in step 513. This prompts the operator to install the IC card 116, or warns the operator that even if the IC card 116 is installed but is incomplete, it must be installed securely.

When the attachment of the IC card 116 is confirmed in step Sll, the process advances to step S15. In step 515, the password registered in the addresses "9A00 to 9A02" of the RAM 124 and the attached IC card 11 are input.
It is determined whether the password matches any of the passwords registered in the RAM 140 of No. 6. As described above, the password numbers of 20 electronic copying machines 10 can be registered in the IC card 116. Therefore, in this step 515, the MPU 120 uses the address "9A00~9A00".
It is determined whether there is data of the same password at any address in the RAM 140 as the password data of "A O2".

If the matching of the PIN numbers is not confirmed, the process proceeds to step 813, and if the PIN numbers are confirmed to match, the process proceeds to step S17. Therefore, even if the IC card 116 is properly inserted into the card receiving section 118, if the PIN number of the electronic copying machine 10 is not registered in the IC card 116, the card insertion table 112 will light up. . Then, the operation after step S17, that is, the operation cannot be executed.

When it is confirmed in step S15 that the password numbers match, the card unit display 112J turns off in step S17. Then, the process advances to step S19, and the process enters a standby state in which the start key 1128 is operated.

When the operation of the start key 1128 is confirmed in step S19, that is, the operation of the star 1 key 112a is confirmed to be the key matrix 130 and the I10 ink face 1
26 into MPU 122, the process proceeds to step 321. In step S21, M
The drive device 134 is driven by the PU 120, and one copy is executed. When one sheet of copying is completed, the process advances to the next step S23.

In this step S23, the data of the total number of copies of the IC card 116 and the electronic copying machine 10 and the data of the number of copies by paper size are each incremented by "1". In this way, the address "8BA4"
~8 B B 5 ” and “9A03 ~ 9A14” are updated. After that, the updated address “9
The data of "A03~9A14°" is transferred to a predetermined address of the RAM 140 of the IC card 116 through the pass line.For example, the recitation number registered at the address "9A00~9A02" of the RAM 124,
If the lock number registered in the address "8B7A-887C" of the RAM 140 matches the data of the updated address "9A03-9A14",
It is transferred to addresses "8B7D to 8B8E"'. In this way, each time a copy is executed, RAM 1 of the main unit is
24 address "9A03-9A14"' data and I
Address “8B7” of RAM 140 of C card 116
D~8B8E” data is updated in the same way,
The latest copy data is retained for both.

Next, referring to FIG. 4, the operation or operation of the service mode of the electronic copying machine 10 will be described based on the flowcharts shown in FIGS. 9A to 9G.

In the first step S25 in FIG. 9A, after the power is turned on, it is checked whether the recent key 112b and the interrupt key 112d are turned on at the same time. If it is not confirmed that they are turned on at the same time, the copy mode shown in FIG. 8 is entered, and the process executes a copy mode routine.

When the electronic copier 10 is confirmed to be turned on at the same time,
switches to service mode. In this case, as described above, the various operation keys and display on the operation panel 110 perform functions different from those in the copy mode.

Immediately after switching to service mode, step S2
7, the first (IA) command number "01" is displayed on the magnification display 112r. This command number "01" indicates the initial state of the service mode. In the initial state, the number display 112
All other indicators on the operation panel 110, such as f, are turned off.

Note that since the magnification display 112r is a 3-digit number display for segments, the command number is not displayed and is performed by partially lighting the segments.

In the next step S29, it is determined whether the zoom up key 112p has been operated. Zoom up key 1
When the operation of 12p is confirmed, the process advances to step S31.
In step S31, the command number at that time is "C93".
”. When the command number “393” is confirmed, the process returns to the previous step 329. Therefore, in step S31, when the command number “C93” is confirmed, the zoom key 112
Even if p is manipulated, the command number no longer changes.

When it is confirmed in step S31 that the command number is not "C93", the process advances to step S33. For example, after the command number "C1" is displayed on the magnification display 112r in the previous step S27, the command number determined in step 831 is naturally "C1", and therefore, it does not return to 329 at this time. The process then proceeds to step S33.

In step S33, the command number is incremented by one. For example, if the command number is "C1" in the previous step S31, the command number is updated to C2" in this step S33. However, the command number is updated to "C5" in the previous step S31. If so, the command number is C1l" in this step S33.
will be updated. This is because, as shown in the table above, there are 15 types of command numbers from "C1" to "C93" including missing numbers, and the command after "C5" is "C1l".
This is because it is °′.

In the next step S35, the command number updated in step S33 of n"li is displayed on the magnification display 112r. Therefore, when the zoom up key 112p on which the command number "C1" is displayed is operated on the magnification display 112ri, If so, in this step S35, the magnification display 1
]2r displays the command number "C2"°.

In the previous step 829, press the zoom up key 112p.
5. Make sure the operation is correct. If the zoom down key 112q has not been pressed, the process advances to step S37, where it is determined whether the zoom down key 112q has been operated. And zoom down key 112
If the operation of q is confirmed, the process advances to step S39.

In step S39, the command number at that time is "C1".
It is determined whether or not. Command number is “01”
If it is confirmed that °' is true, the process returns to the previous step 329. Therefore, if the command number is already C1°, the command number will not change even if the zoom down key 112Q is operated.

If it is not confirmed in step 339 that the command number is "C1", the process advances to step S41. In step S41, the current command number is decremented by one. For example, if the current command number is "C1l"
”, in this step S41 the command number is “
Updated to 05".

After that, the process proceeds to step S35, and the magnification display 112r
t' The updated command number "C5°" is displayed.

If operation of the zoom down key 112q is not confirmed at step knob S37, the process advances to step/343.

In step 543, it is determined whether the current command number of the electronic copying machine 10 is "C1". If the command number "01" is confirmed, the process advances to step S45.

In step 845, it is determined whether the start key 1123 has been operated. In this way, when the command number is "C1" and the operation of the star key 1128 is confirmed, the process proceeds to step S47.

In step S47, the installed IC card 116
The data at addresses "8BA4 to 88B5" in the RAM 140 is the paper size selection key 112o and the same size key 11.
2n, a total of six digits are displayed on the magnification display 112r and the sheet number display 112f.

For example, if the user wants to know the total number of copies made by the installed IC card 116, the user operates the start key 1128 with the command number "C1".

Then, for example, if the total number of copies is 23,456, the magnification display 1
The upper three digits "23" are fully displayed on the display 12r, and the lower number "456" is displayed on the sheet number display 112f. Then, all the LEDs of the paper size display 112Q light up.

When the user wants to know the number of copies for each paper size, the user operates the paper size selection key 1120 to specify the paper size. Then, the paper size display does not indicate the specified paper size in episode 112, and only the LED lights up, and the magnification display 1
12r and the number of copies display 112f display the number of copies of the specified paper size.

The data on the total number of copies executed using the IC card 116 can be stored in three hides at addresses "8 BA4 to 8BB5" of the RAM 140 shown in FIG. 7B, and the data on the number of copies for each paper size can also be stored. is stored in the address of

In step 349, for confirmation by the operator,
The display as shown in FIG. 10F displayed in the previous step S47 is maintained for 5 seconds. Thereafter, when 5 seconds have passed, the process proceeds to step S51, where the display on the sheet number display 112f and the paper size display 112f disappears, and the command number "C1" is displayed on the magnification display 112r as shown in FIG. 10A. be done. Then, the process returns to step S29.

If the operation of the start key 112a is not confirmed in the previous step S45, the process advances to step S53.

In step S53, it is determined whether the reset +-112b and the clear/strike/out key 112e have been operated simultaneously. If simultaneous operations are not confirmed, the process returns to the previous step S29, and if simultaneous operations are confirmed, the process proceeds to step 355.

In step S55, RAM 1 of the IC card 116
40 addresses "8BA4 to 88B5" are cleared. This data is selectively displayed in the previous step S47, and is data indicating the total number of copies used by the IC card 116 and the number of copies by size.

In the next step S57, as shown in FIG. 10B, "oooooo" 1 is displayed in a total of six digits on the magnification display 112r and the sheet number display 112f. Step S5
At step 9, the - display is maintained for 2 seconds. After that, the process proceeds to step S51, and from step S49 to step S5.

B B 5 ”, each data is multiplied, and the copying cost for each specified paper size is calculated.

Note that when calculating the total copying cost using the same size key 112n, the total copying cost is calculated by calculating the copying cost for each paper size and then adding them together.

In the next step S67, the six digits of the copying cost calculated in the previous step 365 are displayed. In this embodiment, the magnification display 112r; and the number of copies display 112f have fewer digits than the number of digits required to display the number of copies, copying cost, etc., so numbers with large numbers of digits such as copying cost etc. I am trying to display it in time division. For example, the maximum unit price for copying costs that can be set is 99.
It costs 99 yen, and the maximum total number of copies is 99.
There are 9999 pieces. Therefore, the maximum value of the copying cost that can be calculated is 10 digits of 99,989,900 yen.01. Therefore, the magnification display 112r and the number display 112

If not confirmed, the process advances to step S215, where it is determined whether the command number is "C55". When the command number “C55” is confirmed, step 521
7, it is determined whether the start key 112a has been operated. When the operation of the start key 1128 is confirmed, the process advances to step 5219 and the paper size selection key 11 is pressed.
2o, the data at addresses 9A15 to 9A28' of the main body RAM 124, that is, the copy unit price for each paper size, is displayed on the magnification display 112r and the number of sheets display 1.
It is displayed on 12f.

For example, if the unit price for an A3 size copy is 12.34 yen, the paper size display 112 will be displayed as shown in FIG. 10E.
The LED indicating "A3" of Q lights up, "12"' is displayed on the double'$ display 112r, and the number of sheets display 1 is displayed.
"-34" is displayed on 12f. Number of sheets display 112
The (-) displayed in f indicates the value of "money". Note that if you do not operate the paper size selection key 112o in
When the start key 112a is operated in step 7, the unit copy price shown is for A3 size.

Here, when changing the registered copy unit price, a new engraving price is set on the magnification display 112r and the number of copies display 112f by operating the numeric keypad 112c and the clear/stop key 112e.

Next, in step S221, the start key 112
It is determined whether or not a has been operated. If the operation is not confirmed, the process advances to step 5223, where the copy unit price is displayed, and it is determined whether 15 seconds have elapsed since -C. When 15 seconds have elapsed, the process advances to step 5227,
The copy unit price display disappears and the magnification display 112r
The original command number "C55"' is displayed and the process returns to step 529.

In the previous step 5215, the command number “C55
” is not confirmed, the process proceeds to step 5229, and it is determined whether the command number is “C91”. If the command number “C91” is confirmed, the process proceeds to step 523.
1, it is determined whether the start key 1128 has been operated. If the operation of the start key 1128 is not confirmed, the process returns to step S29, and if the operation is confirmed, the process proceeds to step 5233.

In step 5233, the total number of copies made by the electronic copying machine with the specified password υ is displayed using the numeric keypad 112c. Note that such input of the PIN number is performed before step 5231. The total number of copies is displayed in six digits on a magnification display 112rJ'j and a number display 112f. Then, after the display is held for 5 seconds in STETSU/5235, the display disappears at step 5237 and the original command number is displayed on the magnification display 112r.
C91° is displayed and the process returns to step 329.

If the command number "C91" cannot be confirmed in the previous step 5229, the process advances to step 5239 and it is determined whether the command number is "C92°". If the command number "C92" is confirmed, the process proceeds to step 524.
1, it is determined whether the reset key 112b and the 1° key in the numeric keypad 112c have been operated at the same time.If it is not confirmed that the reset key 112b and the 1° key in the numeric keypad 112c have been operated at the same time, the process returns to step S29 and is confirmed. The process proceeds to step 5243. In step 5243, the RA of the IC card 116 is
Address of M 140 “8AOO~8 BA 3
”, address 9A of main body RAM 124
The address “9A03” is placed in the area with the password that matches the data “OO~9A02”, that is, the password.
~9A14°9 data will be transferred. Therefore, in the data of the IC card 116 completely inserted into the electronic copying machine 1o, the data in the part C where the same password as the electronic copying machine 1O is registered has been updated.

In step 5239, if the command number is not confirmed to be “C92′′, the remaining command number is “
C93". At this point, step 524
Proceed to step 5, reset key 112b and numeric keypad 112c
The test is whether or not the "7" keys in the ``7'' keys can be operated at the same time! fI is done. If simultaneous operations are not confirmed, the process returns to step S29, and if confirmed, step 5247i:
Proceed, step/fu 5247 tech, rc card 11 ano R
A M 140 (7) Address "8AOO~8BA3'
Address “9A” of main body RAM 124 in the data of
00 to 9A O2” data in the area with the same password is stored in the main unit RA from the IC card 116.
M 124 (7) 7 dresses = 9AO3~9A14''
will be forwarded to. This is useful when replacing the control board, etc.
If there is a risk that the data stored in the RAM 124 of the electronic copying machine 1o may be lost, first transfer the data in the RAM 124 to the IC card 116, and then reinstall it after the control board has been replaced. RAMI24
This is the operation when transferring i data.

(g.) Effects of the Invention In the present invention, data is mutually transferred between the memory of the copying machine and the memory card, so even if the data stored in the memory of the copying machine disappears, , the data can be reproduced by a memory card.

Therefore, the inconvenience that the copy data becomes unknown does not occur.

Furthermore, according to the present invention, not only the data stored in the memory of the copying machine main body disappears during a warm-up period, but also when replacing the memory of the copying machine main body or the printed circuit board on which this memory is mounted. ,It is valid. That is, the data stored in the memory of the copying machine is first transferred and stored on a memory card, then the memory and printed circuit board of the copying machine are replaced, and then the data is stored (stored) in the memory card. If you transfer the existing data to a new memory, the initial data will always be 'A' even if you replace the memory in the copier itself! It is extremely convenient because it is stored in the memo 1; and the initial state is reproduced.
