The copy number display automatically displays 1 immediately after the power of the copying machine is turned on, or after a predetermined period of time has elapsed after copying is completed or the final key is selected. (Hereinafter referred to as auto clear) Also, when the clear key is pressed, 1 is similarly displayed.

When the interrupt key 102 is pressed, the copy number display displays 1 instead of the number that was displayed up until then, and then displays the set number of copies by manual key operation during the interrupt mode. Figures 4-a, 4-b, and 4-a are general flowcharts of the microcopy:x--1 (D program) in the timepiece controller 56.

FIG. 5 shows a list of flag setting and reset conditions used in the general flowcharts shown in FIGS. 4-a to 4-a.

Next, with reference to Figures 2, 3, and 5, see Section 4-a.
The general flowcharts shown in Figures 4-C will be explained. When the plug 51 is inserted into a power outlet or when the backup power supply 53 is connected to the clock controller 56, the microcomputer (hereinafter referred to as "microcomputer") in the clock controller 56 starts operating, and as shown in FIG. The program is executed as shown in the flowchart of Figure 4-a. First, in step l of Figure 4-a,
Initialize H and AM in the clock controller 56, change the display of the operation unit (A2B) to the CLOCK mode display, and output data to the display driver 57 through line L2 in order to display OO:00 on the clock display.

Furthermore, the count number of the internal timer of the microcomputer in the clock controller 56 is set in the RAM and the clock timer is started. After the internal timer counts up, it interrupts the microcomputer program of the clock controller 56 and repeatedly updates the clock timer data every minute.

At this stage, the power relay (Kl) 61 of the copying machine has not yet been turned on, so all the displays on the operation section (kl 67) remain off.

Next, the operation when the main switch 127 is turned on and off by manual operation will be described.

fl) When the main switch 127 is turned on by manual operation Step 2. Step 4. In step 7, it is determined whether the time is a timer-controlled power-on time, power-off time, or electric power off notice start time. In this case, since the plug 51 has just been inserted, no time has been set for any mode, so proceed to step 9 and check the state of the switch on the operating section (5) 58 and the operating section (13) 6.
105 on the numeric keypad above 7. The state of the clear key 106 is input to the clock controller 56 through line L4, and the state is stored in the RAM.
Set to . Next, in step 10, FLAG(MAIN
ON), but since it has not been set yet at this stage, the process advances to step 12. In step 12, the key data in the RAM is checked and it is determined that the main switch 1270"l" (ON) has been pressed, and the process proceeds to step 13, but at this stage the FLAG (MAINO)
N) has not been set, so proceed to step 17, immediately turn on the power relay (Kl) 61, and record the ON time R.
Store in AM. Also, set FLAG (MAIN ON) to remember that the main switch 127 has been turned on. Reset FLAG (ONTIMIii) on the sail. FLAG (ON TIMg) will be explained in section (6) below. Next, in step 18, RA
By checking the key data in M, it is determined that 10'' (OFF) of the main switch 127 is not pressed, and the process proceeds to step 20, where it is determined whether FLAG (OFF TIMg) is set. Since it is not set, proceed to step 25.Step 25
Then, the state of the switch 128 is determined, and if it is the time set mode, the process advances to step 26, and if it is copy mode, the process returns to step 2. First, let me explain what happens when copy mode is selected.〇Step 2. Step 4. The judgment is still N in step 7.
Since it remains 0, in step 9 you can again check the state of the switch on the operation section (6) 58 and the numeric keypad 10 on the operation section (direction 67).
5. The state of the clear key 106 is read and RAMK data is set, but at this stage it is assumed that no switch is pressed. Next, the process proceeds to step 10, but at this stage, since FLAG (MAIN ON) is set, it is determined that the power relay (Kl) 61 of the copying machine is turned on, and the process proceeds to step 11, where the apparatus controller 6
Data is exchanged with 5. To explain the data here, data from the clock controller 56 to the device controller 65 is transmitted from the numeric keypad 105. The clock controller 56 sends the status of the clear key 106 and receives data on various statuses of the copying machine from the device controller 65. When the copying device is in the process of copying, or within a predetermined period of time after the copying operation is completed (for example, during 1111 during auto clear)
If you are requesting prohibition of turning off the power,
Set F'LAG (OFf"I NHI B I T ) and reset it when the prohibition is released. Next, proceed to step 12 again, but in this case main switch 127
Since there is no 'l'' (on) input, the process proceeds to step 16, where the state of F' LAG (ON 'I'IME) is determined, but since it has yet to be set, the process proceeds to step 18.

After step 18, the same steps as described above are performed until step 20. Proceed to step 25 and switch 128
Step 2. until switches to time set mode.
Step 4. While determining the time match in step 7,
Read the switch status in step 9, and step 11
The clock controller 56 continues to communicate data with the device controller 8. Of course, the internal timer of the microcomputer continues to count in parallel with the progress of the above steps, and the clock controller 56 continues to communicate with the device controller 8. The time continues to be counted and the clock display 139'c is updated every minute.

(2) When the main switch 127 is turned off by manual operation When the main switch 1270 "0" (off) is input in step 9 in the progress of the steps described in section 11 above,
1-LAM, the data is determined in step 18, the process proceeds to step 19, and the power relay (Kl) is set.
61 is turned off, fi''LAG (MAINON) is reset, the fact that the power of the copying apparatus is turned off is memorized, and data communication with the apparatus controller 5 is prohibited in step IO and step 11.

Next, the time set mode will be explained.

When setting the time in the f31cLOcK mode, first switch the switch 128 from the copy mode to the time set mode, and in step 9 the state is read and R
Data is set in AM, then the program progresses,
When step 25 is reached, the mode is determined, and since it is the time set mode, the process proceeds to step 26. If there is no input from the switch on the operation unit (5) 58 or the numeric keypad 105 or clear key 106 on the operation unit (c) 67, step 26. Step 28. Step 30. Step 32. All judgments in step 33 are NO and step 3
Since 4 is YES, proceed to step 39 and set FLAG(
C) (ECK) is determined, but since it has not been set yet at this stage, the process returns to step 2 and repeats from the start of the above (3). Also, to explain the case where the user inputs 12:30 using the numeric keypad 105 in order to set the time at this stage, when the user presses 1 first, the input is read in step 9, and the data input in step 28 is read. It is determined that the numeric keypad is human-powered, and step 2
Proceed to 9 and display 00:01 on the display 139. Similarly to 0, 2°3.0 is read and 00:1 is displayed on the display 139.
2゜01:23, 12:30 are displayed sequentially 0 Next, when the user presses the 5TART key 135, R is displayed in step 9.
The data set in A ivi is determined in step 33, and the process further advances to step 43. In this case, since the mode is CLOCK mode, the process advances to step 44. And display 13
Since the numerical value displayed on the screen 9, that is, the numerical value set by the user, has already reached 4 digits, the process proceeds to step 45, and it is determined whether or not the ONTIME mode is selected, but if the answer is NO, the process proceeds to step 47. . In step 47, OF FT
It is determined whether or not it is the IME mode, but since the answer is NO, the process advances to step 49 and is indicated by the display counter of the CLOCK mode. ,CLOCK
In the case of the CLOCK mode, there cannot be multiple time sets, so the display counter always remains at 00, and the time data in the RAM address represented by the display counter 0 in the CLOCK mode always represents the current time, and this data is The microcomputer's internal timer continues to add time every minute. Next, the process advances to step 50, where the numerical data on the temporary memory for manual numeric keypad operation is cleared, and the display 139 is cleared.
The time set in will start counting as a clock display.

Furthermore, FLAG (CHgCK) is reset, but C
i, FLAG (CHECK) in case of OCK mode
is never set, so it will be explained in section (5). In the explanation so far, we have talked about the case where 4 digits of numerical data were input, but if only 3 digits were input and 5 digits were input.
If the TART key 135 is pressed, in step 44, since 4 digits of numerical data have not been input, the process proceeds to step 51, and in this case, 5 TAI (T key 1350 manpower is available, so the process proceeds to step 50. In this case, Step 49
Since the time is skipped, no new time data is set in step 50, and the old time at which counting was continued is displayed on the display 139.

(41 ON TIME mode or OFF TIVi
When setting the power on time or power off time in E mode, the setting method is the same for both the power on time and the power off time, so only the power on time will be explained. When the user presses the ON TIME mode key 133, the state is read and set in RAM in step 9. Then, in step 30, it is determined that it is the ON TIM13 mode key, and the process advances to step 31. Step 3
In step 1, the ON TIME3 mode display 130 is turned on, and the - carrying time is displayed on the display 139. this is,
If the time is being set for another time, the data on the temporary memory for the numeric keypad that was being set is cleared and the power-on time can be set.
Similarly to item 3), the numerical data input to the RAM in step 9 is judged in step 28, and after 4 digits are displayed on the clock display 139 in step 29, the SET key 13 is pressed.
If 8 is input, it is determined in step 32 and step 44. Proceed to step 45.

In step 45, it is determined whether or not it is oNTIME mode, but in this case, it is ON TlMg mode, so step 46
Proceed to step 49, and judge whether the difference between the power off time that has already been set and the power on time data set this time is T3 or more. The power on time and specified data are displayed on the ONTIME mode display counter.
Store to AM address. However, if there is no power off time that has already been set, the process advances to step 49 unconditionally. In addition, in OFF TIME mode, the above judgment is
Step 47. Change to step 48.

Similarly, it is determined whether or not there is a difference of T2 or more between the power-on time that has already been set and the power-off time data set this time on the temporary memory for manual numeric keypad operation. From the above button, the time between the power on time and the power off time under timer control will never be less than the fixed time T3, and due to an error in setting the power on time or power off time under timer control, the copying machine will be turned on. This avoids the inconvenience of being turned off immediately. Note that the predetermined time T2 may be set to, for example, the time required to make a copy of the minimum size (1 copy cycle).

To explain the display counter here, when storing the power-on time and power-off time in the power-on time or power-off time storage area in RAM in the order set by the user, the display color/color for that address is changed. Allocate.

In other words, if three power-on times are set, 1°2.3 of the display counter will be assigned in the order in which they are set, and the set power-on times will be displayed on the display 139 according to the number of times the CHECK key 136 is pressed. The time is displayed sequentially.

Therefore, when the fourth power-on time is set, it is stored at the RAM address corresponding to 4 on the display counter. The value of this display counter, that is, the number of power-on times or gap-off times to be set, may be determined depending on the capacity of the RAM.

Return to the explanation of the rehi flowchart.

Next, proceed to step 50, clear the numerical data on the temporary memory for manual numeric keypad operation, and CLOCK the 1 mode.
mode, the display 130 is turned off, and the display 129 is turned on. The current time is also displayed on the clock display 139. Up to this point, we have described the case where 4 digits of numerical data have been input, but if up to 3 digits have been input, press the 5IFT key 13.
If 8 is pressed, step 44. SE at step 51
The input of the T key 138 is invalidated. However, in this case, the 3-digit numerical data that has been input up to that point is retained as is, and it is possible to continue inputting the 4th digit. After entering 3 digits again,
If you want to clear the previous 3-digit input, press the clear key 106, which is determined in step 26, and in step 27, the numeric data input so far on the temporary memory for the numeric keypad is cleared, and the mode is changed. C
Set to LOCK mode, turn off the display 130, and turn off the display 1.
Turn on 29.

Note that the difference between the power on time and the power off time is a certain time 'I
If it is less than 7, the numerical data on the temporary memory for manual numeric keypad operation will not be cleared, and the mode will also be set to Ci or OCK.
Since the mode is not set, the display 130 remains lit.

Therefore, when setting the power on time or power off time, the user can determine whether he or she has set the timer at the correct time by looking at the CLOCK mode display 129 or the clock display.

(5) When confirming and canceling the set power on time (or power off time) ON TIME mode and OFF TIMt (Since both modes are the same, only the ON'rIMg mode will be explained.

When the ON TlMg mode key 133 is pressed, its state is read in step 9 and set in the RAM, similar to item (4). Next, it is determined in step 3o and step 3
1, the ON 'irM, g mode display 130 is lit and the time is displayed on the hand clock display 139. Subsequently, when the CHgCK key 136 is pressed, step 3
It is determined in step 5 and the process proceeds to step 36. In step 36,
Set FLAG (CHECK). From now on, the ON TIME mode check is stored until F'LAG (C1'ECK) is reset. At the same time, clear the numerical data in the temporary memory for manual numeric keypad operation, and turn on the same mode (in this case, ON).
Clears the numerical data when the time is in the middle of setting in TIME mode). Increment the display counter. Since the display counter is 0 in the reset state when the CHECK key 136 is pressed for the first time, it becomes 1 here. Next, in step 37, if the data in the address I (A M) corresponding to the display counter l is set, the process proceeds to step 39, and
Whether or not K) is set is completely ON.
Determine whether the check is in ME mode or not, and
If G (CHEcK) is in the reset state and the ON TIME mode is not checked, return to step 2, but in this case, immediately after the CHECK key 136 is pressed, FLAG (
Since CHECK) is being set, the process advances to step 40 and the I(, AM address data, t#, corresponding to the display counter l) is set.
7. The set power-on time is displayed on the clock display 139, and the process proceeds to step 41. In step 41, CANCB
It is determined whether the L key 137 has been pressed, but since it is not pressed at this stage, the process returns to step 2 and the next CHnC is pressed.
K key reads human power. And CHEC by user
If you do not have the K key manually, determine NO in step 35, proceed to steps 39 and 40, and display 1 on the display counter.
The data in the RAM address corresponding to is continued to be displayed on the clock display 139. Next, if the user inputs the CI (ECK key 136) again, the process advances to step 35 and step 36, and the display counter is incremented to [7.2]. In step 37, data is set in the RAM address corresponding to display counter 2. If it is set, the process proceeds to step 39 and step 40, and the data in the RAM address corresponding to the display counter 2, that is, the second set power-on time, is displayed on the clock display 139.
Display above. The user repeats the same action N times, and
If you want to cancel the set power-on time, press the CANCEL key 137 to cancel step 4.
1, the input of the CANCBL key 137 is determined, and the process proceeds to step 42, where the data at the RAM address corresponding to the display counter (N+1) is shifted to the RAM address corresponding to the display counter N, and similarly, the data at the RAM address corresponding to the display counter (N+1) is shifted to the RAM address corresponding to the display counter N. Shift the data sequentially and cancel the set power-on time in the RAM address (corresponding to the display counter N). Furthermore, the mode is set to CLOCK mode, the display 130 is turned off,
The display 129 is turned on and the current time is displayed on the clock display 139. At the same time, reset the display counter)
Reset L FLAG (CH13CK),
Return to step 2 and read the next switch input.

In the above explanation, if it is determined in step 37 that no data is set in the RAM address corresponding to the display counter M, the process proceeds to step 38, sets the display counter to 1, and proceeds to step 39. This allows the user to
Each time the ECK key 136 is pressed, the set power-on time can be checked repeatedly on the clock display 139. Further, at the first time, that is, when f-night is not set at the ELAM address corresponding to the display counter l, that is, when no power-on time is set, the display becomes blank.

Also, during the operation of either (4) or (5) above, 5TAJ
By inputting the 'tT key 135, the mode being executed as determined in step 33 or step 51 is terminated.
It enters the CLOCK mode, turns on the display 129, displays the current time on the clock display, and prepares for reading the next switch input. Next, the operation of each mode set as described above will be explained.

(6) When the current time is the set power-on time.

It is determined whether all the power-on times set in step 2 match the current time, and if they match, proceed to step 3 and set FLAG (ONTIMEi). Then, in step 16, FLAG(ON T

When the power-off prohibition request from the device controller 65 is released, the process proceeds to step 22. In step 22, it is determined whether or not a certain predetermined time has elapsed since the power was turned on, and if it is within 15, step 24 is performed. Go to the power relay (

TIMW) and cancels power off by timer control.

This is done by comparing the current time with the power-on time data stored in the RAM in step 17. This allows the user to manually turn off the power to the copying machine.
Furthermore, the inconvenience that the power is turned off by timer control after turning on the device and before the user starts using it can be solved.

If it is not within time T1, proceed to step 23, turn off the power relay (Kl) 61 in the same way as turning off the main switch 127 manually, and turn F LAG (MAIN ON
), and then proceed to step 24 to reset FLAG(OF
F_TIME) and completes the operation.

(8) Operation to indicate that the timer-based power-off time is approaching, and when canceling the timer-based power-off.

In step 7, it is determined whether the current time is before T2 of all the set power off times, and if they match, the process goes to S'1rEP 8 and POWffl-
Turn on the L OFF ALABJM display 140 and
Set G (OFF ALARM). This allows the user to know that the timer-controlled power off time is approaching. In this case, if the user wishes to continue the copy process, manually switch the main switch 1.
Step 12 by pressing 270""l" (ON).
The program proceeds to step 13, and the state of FIAG (OFF ALAFLM) is determined in step 14. In this case, since POWER OFF ALAFLM is being displayed and the flag is set, the program proceeds to step 15. In step 15, K F'LAG (OFF AT, A

) is not set. Therefore POWI OFF' AL
By pressing the main switch 127 even while ARM is being displayed, the power supply is not turned off by the timer.

In addition, in this embodiment, POWEROFF ALA II,
The M display 140 may be displayed by sound.

Furthermore, although the time during which the power is on and the time during which the power is off are made the same in section (4), there is no particular need to make them the same. Also in paragraph (8).

Although the setting time when performing the POWEROFF ALARM display is set to <Tt, which is the same as in section (4), there is no need to limit it to this. Further, if the program is such that the power is turned on by a timer within a predetermined time after the power is turned off by manual operation, turning on the power by the timer may be prohibited.

Although this embodiment has been described with respect to setting the power on/off time or time, the present invention can also be applied to setting the time or time required for auto-clearing the number of sheets. can be used not only for copying machines but also for other image reproduction devices such as facsimiles, printers, etc.

Effects As explained above, according to this embodiment, reservation control such as turning on/off the power supply etc. can be easily performed on the operation panel of the copying apparatus. Further, since the time or time for turning on/off the power supply, etc. can be set using the number-of-copies input means, an extra input means is not required.

Historically, while the copying device is copying, or within a predetermined period of time after the copying operation has finished (for example, during auto clear), the power off time can be delayed by timer control, so it is possible to delay the power off time by timer control during the copying operation. etc. can be prevented. Therefore, the user is saved from having to make a copy again. Further, since the power is not turned off or the like within a predetermined time after the copying operation is completed, the user can easily replace the original and make a new copy. In addition, after turning on the power manually, the timer prohibits the stain source from being turned off within a predetermined time.
It is possible to prevent the inconvenience that the power supply, etc. is turned off by a timer before the user manually turns on the main switch to perform copying.

Furthermore, according to this embodiment, not only can the timer notify the user that the power-off time is approaching, but when the user wants to continue using the copying machine, the user can turn on the main switch while the power-off notice is displayed. By doing so, it is possible to prohibit power off, etc. using a timer. Therefore, the user can continue using the copying apparatus by simple operations even when the power-off time approaches.

Furthermore, according to this embodiment, if the time that the power source, etc. is on or the time that the power source, etc. is turned off is shorter than the predetermined time, setting of the power on time, etc. or power off time, etc. is prohibited. This prevents troubles such as the power being turned off immediately after being turned on due to the user setting the wrong time.

Furthermore, according to this embodiment, the power-on time etc. by a timer, etc.
Since it is possible to set a plurality of power off times, etc., the usage time of the copying machine can be freely set according to the work. Moreover, since the set power-on time, power-off time, etc. can be sequentially checked by simple key operations, it is also possible to easily check the times set by others. Further, since the power on time, power off time, etc. can be displayed on the clock display, no extra space is required.

Therefore, the user can use the image reproduction device without being confused by various troubles associated with reservations such as turning on/off the power, etc. (for example, the power turns off during copying). This saves time wasted due to resetting.

As described above, according to the present invention, various troubles associated with reservations for turning on or off the power source, etc. can be solved.
