Description

The present invention relates to reservation control of a power supply or the like of an image reproducing device.

Conventionally, the power of the copying machine is turned on / off by a user's manual operation. In the office, the user turns on the power switch at the beginning of the morning, and at the end of the day, the end user or a dedicated administrator turns off the power. Was there. Therefore, the switch is often forgotten to be turned on and forgotten to be turned off, and when power is wasted and copying is attempted in a regular work, the power is turned off and time is lost. In order to solve these problems, in the past, the invention was devised to eliminate the wait time by using an auto-shut-off function that automatically turns off the power after a certain period of time after the end of the copying process, or by using a pressure fixing device. In case (2), the auto shut-off time is fixed, so that it is difficult for the user to use, and in the case of the latter, there is a drawback in that fixing to a high-speed copying apparatus has a problem in fixing property.

Therefore, a copying machine that reserves the power-on time and power-off time has been considered.

However, if the time when the operator turns on the power switch for image reproduction is immediately before the reserved off time, the following inconvenience occurs.

The temperature of the fixing device of the copying machine has dropped, and the power is turned off before the temperature reaches a level at which copying is possible.

If it takes time to select a document to be copied or place the document on the document table, the power is turned off before the copy button is pressed.

Before the copying is started, the user temporarily leaves the copying machine by calling a telephone or the like, and then when returning to the copying machine, the power is off.

In this way, depending on the time when the power switch is turned on,
The power supply to the apparatus is turned off before the image reproduction is started, and the operability deteriorates.

The present invention has been made in view of the above points, and an object of the present invention is to provide an image reproducing apparatus capable of eliminating the inconvenience when the power supply is turned off by the timer and improving the operability.

That is, according to the present invention, a power switch that is turned on and off to supply power to the device, power supply means for supplying power to the device, time measuring means for outputting time information, and power supply to the device are turned off. Setting means for setting a desired off time, storage means for storing the off time set by the setting means, and the power switch in the on state,
The off time stored in the storage means is compared with the time information output from the time counting means, and when the time information is the same, a control means for turning off the power supply to the apparatus by the power supply means and an image forming means are provided. If the off time stored in the storage means reaches the off time within a predetermined time after the power switch is turned on, the control means keeps the off time stored in the storage means and sends the data to the device. After stopping the turning off of the power supply, the power supply to the apparatus is maintained regardless of whether or not the image forming means is performing the image forming operation thereafter, and after a predetermined time has elapsed since the power switch was turned on. It is an object of the present invention to provide an image reproducing device that turns off the power supply to the device when the off time stored in the storage means comes.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a copying machine apparatus to which the present invention can be applied, and the structure and operation will be described.

The surface of the drum 1 is composed of a three-layer seamless photosensitive member using a CDS photoconductor, is rotatably supported on the shaft, and is operated by turning on a copy key.
Starts rotating in the direction of the arrow.

When the drum 1 is rotated for a predetermined time and the potential control process (pre-process) is completed, the document placed on the platen glass 36 is illuminated by the illumination lamp 23 integrated with the first scanning mirror 24, and its reflected light is reflected. Are scanned by the first scanning mirror 24 and the second scanning mirror 25. The first scanning mirror 24 and the second scanning mirror 25 move at a speed ratio of 1: 1/2 to allow the lens 3 to move.
The original is scanned while the optical path length in front of 0 is always kept constant.

The reflected light image passes through the lens 30, the third mirror 26, and the fourth mirror 27, and then forms an image on the drum 1 in the exposure unit.

The drum 1 is simultaneously neutralized by the pre-exposure lamp 8 and the pre-charger 2 and then corona-charged (for example, +) by the primary charger 3. Thereafter, the drum 1 is subjected to the slit exposure of the image irradiated by the illumination lamp 23 in the exposure section.

At the same time, AC or primary corona neutralization (for example, negative polarity) is performed by the secondary charger 4, and then the surface is uniformly exposed by the overall exposure lamp 9 to form a high-contrast electrostatic latent image on the drum 1. To do. The electrostatic latent image on the photosensitive drum 1 is then developed by the developing roller of the developing device 7 to be visualized as a toner image, and the toner image is transferred by the transfer charger 5.

The transfer paper in the upper cassette 13 or the lower cassette 14 is fed into the machine by the paper feed roller 11 or 12, and the register roller 15 takes accurate timing.
The image is sent toward the photosensitive drum 1, and the leading edge of the latent image and the leading edge of the paper can be matched at the transfer portion.

Then, the toner image on the drum 1 is transferred onto the transfer paper while the transfer paper passes between the transfer charger 5 and the drum 1.

After the transfer is completed, the transfer paper is separated from the drum 1 by the separation belt, guided to the fixing rollers 32 and 33 by the conveyance belt 17 via the paper detection sensor 16, and fixed by heating, and then the discharge roller 42 detects the paper detection sensor. It is discharged to the tray 47 via 18.

Further, 29 is a carrying fan for surely carrying the transfer paper. After the fixing is completed, the fixing roller is cleaned by the web 20.

After the transfer, the drum 1 continues to rotate, and the cleaning device 6 including a cleaning roller and an elastic blade cleans the surface of the drum 1 and collects the collected toner into the discharged toner container 43 through the pipe 45, and proceeds to the next cycle. .

The drum 1, charging device 2, 3, 4, developing device 7, exposure lamp 23, mirrors 23 to 27 lens 30, etc. in FIG. 1 correspond to the image forming means of the present invention.

FIGS. 4-a, 4-b, and 4-c are general flow charts of the program of the microcomputer in the timepiece controller 56.

FIG. 5 is a list of flag setting and reset conditions used in the general flow charts of FIGS. 4-a to 4-c.

Next, referring to FIG. 2, FIG. 3 and FIG.
The general flow chart of FIG. 4-c will be described.
When the program 51 is inserted into a power outlet or the back-up power source 53 is connected to the timepiece controller 56, a microcomputer (hereinafter referred to as a microcomputer) in the timepiece controller 56 starts its operation, and FIGS. Execute the program as shown in the flow chart of Figure 4-c. First, in step 1 of FIG. 4-a, the RAM in the timepiece controller 56 is initialized and the operation unit (A) 5
The display of 8 is set to the CLOCK mode display and 00:
In order to display 00, the data is output to the display driver 57 through the line L2.

Further, the count number of the internal timer of the microcomputer in the timepiece controller 56 is set in the RAM and the timepiece timer is started. Internal timer is clock controller 5 after counting up
The program of the microcomputer 6 is interrupted, and the data of the clock timer is updated every minute.

At this stage, since the power relay (K1) 61 of the copying machine is still turned on, all the indicators of the operation unit (B) 67 remain off.

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

(1) When the main switch 127 is turned on by a manual operation: Continuing from step 1 above, it is determined in step 2, step 4, and step 7 whether the power on time, power off time, or power off advance warning start time is controlled by the time timer. To do. In this case, since the plug 51 has just been inserted and no mode has been set for any time, the operation proceeds to step 9 and the operation section.
The state of the switch on (A) 58 and the states of the numeric keypad 105 and the clear key 106 on the operation section (B) 67 are input to the timepiece controller 56 through the line L4 and set in the RAM. Next, at step 10, the state of FLAG (MAIN ON) is judged, but since it has not been set at this stage, the routine proceeds to step 12. At step 12, the key input data in the RAM is checked and the main switch 127 is set to "1".
It is judged that (ON) has been inserted and the process proceeds to step 13, but at this stage FLAG (MAIN ON) is not set, so the process proceeds to step 17 and immediately turns on the power relay (K1) 61, Store in RAM. FLAG
(MAIN ON) is set and the fact that the main switch 127 is turned on is stored. Furthermore, the FLAG (ON TIME) is reset. FLAG (ON TIME) will be explained in section (6) below. Next, at step 18, the main switch 127 is set to "0" (off) by checking the key input data in the RAM.
If it is judged that is not pressed, proceed to step 20 and FLAG
It is determined whether or not (OFF TIME) has been set, but since it has not been set at this stage, the process proceeds to step 25. At step 25, the state of the switch 128 is judged, and if the time set mode, the process proceeds to step 26, and if it is the copy mode, the process returns to step 2. First, the case where the copy mode is selected will be described.

In step 2, step 4 and step 7, the judgment is still NO.
Since it remains as it is, in step 9, the state of the switch on the operation unit (A) 58 and the ten key 105 on the operation unit (B) 67,
The state of the clear key 106 is read and data is set in the RAM, but at this stage it is assumed that no switch has been pressed. Then proceed to step 10, but at this stage,
Since FLAG (MAIN ON) is set, it is judged that the power relay (K1) 61 of the copying machine is turned on, and the process proceeds to step 11 to communicate data with the device controller 65. Explaining the data here,
From the clock controller 56 to the device controller 65,
The state of the ten key 105 and the clear key 106 is sent, and the clock controller 56 receives data of various states of the copying machine from the apparatus controller 65. If the copying machine is in the process of copying, or within a predetermined time after the copying is completed (for example, during the auto clear time), or if prohibition of power-off is requested, set FLAG (OFF INHIBIT). And reset when the ban is lifted. Next, the process proceeds to step 12 again, but in this case, since there is no "1" (ON) input to the main switch 127, the process proceeds to step 16.
The state of FLAG (ON TIME) is judged, but since it is still set, the process proceeds to step 18. After step 18, the same steps as described above are performed to proceed to step 20 and step 25, and until the switch 128 is switched to the time set mode, step 2, step 4, and step 7 judge the coincidence of time. On the other hand, at step 9, the state of the switch is read, and at step 11, the clock controller 56 continues data communication with the device controller. Of course, the count of the internal timer of the microcomputer progresses in parallel with the progress of the step, the time counting is continued from the initial state of the clock set in step 1, and the clock display 139 is updated every minute.

(2) When the main switch 127 is turned off by the manual operation, the “0” (off) input of the main switch 127 is turned to R at step 9 in the progress of the step described in the above (1).
Set to AM, judge the data in step 18, proceed to step 19, turn off the power relay (K1) 61, reset FLAG (MAIN ON), and judge that the power of the copying machine is turned off. Then, in steps 10 and 11, data communication with the device controller 15 is prohibited.

Next, the time set mode will be described.

(3) When setting the time in the CLOCK mode, first, when the switch 128 is switched from the copy mode to the time set mode, the data is set in the RAM whose state is read in step 9, and then the program proceeds. When reaching step 25, the mode is determined here, and the process proceeds to step 26 because it is the time set mode. When there is no input from the switch on the operation unit (A) 58 and the numeric keypad 105 and the clear key 106 on the operation unit (B) 67, all the judgments of Step 26, Step 28, Step 30, Step 32, Step 33 are NO. Then, since step 34 is YES, the process proceeds to step 39, and FLAG (CHEC
Since it is not yet set at this stage to judge K), return to step 2 and repeat from the start of the above (3). At this stage, the case where the user inputs 12:30 with the ten keys 105 to set the time will be explained. First, when 1 is pressed, the input is read in step 9, and the data input in step 28 is read. Is determined to be a ten-key input, the process proceeds to step 29, and the display 13
9: 00: 01 is displayed. Similarly, 2, 3, 0 are read, and 00:12, 01:23, 12:30 are sequentially displayed on the display device 139. Next, when the user presses the START key 135,
The data set in the RAM in step 9 is judged in step 33 and further proceeds to step 43. In this case, CLOC
Since the mode is K mode, the operation proceeds to step 44. Then, since the numerical value displayed on the display unit 139, that is, the numerical value set by the user has already reached four digits, the process proceeds to step 45, and it is judged whether or not the mode is the ON TIME mode. However, since it is NO, the process proceeds to step 47. . In step 47, it is judged whether or not it is the OFF TIME mode, but since it is NO, the process proceeds to step 49 and CLOC.
Stores a 4-digit numerical value to the RAM address indicated by the display counter in K mode. The display counter will be explained in section (4). However, in the CLOCK mode, since there can be no multiple time sets, the display counter will always remain 0.
The time data in the RAM address represented by the display counter 0 in OCK mode always represents the current time, and this data is
The internal timer of the microcomputer keeps adding time every minute. Next, in step 50, the numerical data on the temporary memory for ten-key input is cleared, and the time displayed on the display 139 starts counting as a clock display. Furthermore, FLAG (CHECK) is reset, but in CLOCK mode, FLAG (CHECK) is not set, so (5)
The explanation is given in section. In the above description, the case where four-digit numerical data was input was described, but when the START key 135 is pressed with only three-digit input, the four-digit numerical data is input in step 44. If not, the program proceeds to step 51. Since the START key 135 is input here, the program proceeds to step 50. In this case, since the step 49 is skipped, the time data is not newly set at the step 50, and the old time when the counting is continued is displayed on the display 139.

(4) When setting the power-on time or the power-off time in the ON TIME mode or the OFF TIME mode, the method of setting is the same for both the power-on time and the power-off time, so only the power-on time will be described. When the user presses the ON TIME mode key 133, the state is read in step 9 and set in the RAM. Then, it is determined in step 30 that the mode is the ON TIME mode, and the process proceeds to step 31. In step 31, the display device 130 in the ON TIME mode is turned on, and the shared time is displayed on the display device 139. This is for clearing the data on the temporary memory for ten-key input, which was in the middle of the set, during the other time set, so that the power on time can be set. Next, as in (3), step 9
Numerical data input to the RAM at step 28 is judged at step 28, four digits are displayed on the clock display 139 at step 29, and then the SET key 138 is pressed.
Then, it is judged and the process proceeds to step 44 and step 45. In step 45, it is judged whether or not the mode is the ON TIME mode. In this case, since it is the ON TIME mode, the process proceeds to step 46, and there is a difference of T ₂ or more between the power off time already set and the power on time data registered this time. Determine whether or not
If T ₂ or more, the process proceeds to step 49, where the power-on time on the temporary memory for numeric keypad input and designated data are turned on.
Store to the RAM address indicated by the display counter in E mode. However, if there is no power-off time that has already been set, the process proceeds unconditionally to step 49. In the OFF TIME mode, the above judgment is changed to step 47 and step 48. Similarly, the power-on time already set and the power-off time data on the temporary memory for numeric keypad input at this time are stored. Determine if the difference is more than T ₂ . Due to the above, the time between power-on time and power-off time by timer control does not become less than a certain time T _2, and after the copying machine is turned on due to a mistake in setting the power-on time or power-off time by timer control. The inconvenience of being turned off immediately can be avoided.

To explain the display counter, when the power-on time and the power-on time are stored in the power-on time or power-off time storage area in the RAM in the order set by the user, the display counter is assigned to that address. . That is, assuming that the three power-on times have been set, the display counters 1, 2, ...
3, the set power-on time is sequentially displayed on the display 139 in accordance with the number of times the CHECK key 136 is input. Therefore, when the fourth power-on time is set, RA corresponding to 4 of the display counter is set.
It is stored at the M address.

Next, in step 50, the numerical data on the temporary memory for ten-key input is cleared, the mode is set to the CLOCK mode, the display 130 is turned off, and the display 129 is turned on. Also, the current time is displayed on the time display 139. Up to this point, the case has been described in which four digits of numerical data have been input, but if the SET key 138 is pressed while three digits have been input, the SET key 138 is pressed in steps 44 and 51.
Is invalidated. However, in this case, the 3-digit numerical data that has been input up to that point is retained as is, and 4
The digit can be entered. After entering 3 digits, the previous 3
If you want to clear the digit input, enter the clear key 106 to make a determination in step 26. In step 27, the numeric data on the temporary memory for numeric keypad input up to that point is cleared, and the mode is set to CLOCK mode. The display 130 is turned off and the display 129 is turned on.

If the difference between the power-on time and the power-off time is less than the fixed time T ₂ , the numerical data in the temporary memory for numeric keypad input is not cleared and the mode does not change to the CLOCK mode, so the display unit 130 lights up. Remains as it was.

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

(5) Set power on time (or power off time)
ON TI mode and OFF TIME mode are the same when confirming and canceling.
Only ME mode will be explained.

When the ON TIME mode key 133 is pressed, it is read in step 9 and set in the RAM as in the case of item (4). Next, in step 31 judged in step 30, the display device 130 in the ON TIME mode is turned on and the time display appears on the shared clock display device 139. Then, when the CHECK key 136 is pressed, the determination is made in step 35, and the process proceeds to step 36.
At step 36, FLAG (CHECK) is set. After that, the check in ON TIME mode is memorized until FLAG (CHECK) is reset. At the same time, the numeric data in the temporary memory for numeric keypad input is cleared, and the numeric data is cleared when the time is being set in the same mode (in this case, ON TIME mode). Further, the display counter is incremented. Display counter is CHEC
When the K key 136 is pressed first, the value after reset is 0, so it becomes 1. Next, if the data in the RAM address corresponding to the display counter 1 has been set in step 37, the process proceeds to step 39 and FLAG (CHECK)
Is set or not, that is, whether it is a check in ON TIME mode. If FLAG (CHECK) is in reset state and not in ON TIME mode, return to step 2 but check in this case. Since FLAG (CHECK) is being set immediately after the key 136 is pressed, the process proceeds to step 40, the data of the RAM address corresponding to the display counter 1, that is, the set power-on time is displayed on the clock display 139, and the process proceeds to step 41. . In step 41, it is judged whether or not the CANCEL key 137 has been input, but since it has not been pressed at this stage, the process returns to step 2 and the next CHECK key input is read. If the CHECK key is not input by the user, NO is determined in step 35, and the data in the RAM address corresponding to 1 of the display counter is continuously displayed on the clock display 139 in step 39 and step 40. Next, when the user again inputs the CHECK key 136, the display counter is incremented by advancing to step 35 and step 36, and the data is set to 2 in the RAM address corresponding to the display counter 2 at step 37. If it is set, the process proceeds to step 39 and step 40 to display the data in the RAM address corresponding to the display counter 2, that is, the second set power-on time on the clock display 139. The user repeats the same operation N times to cancel the Nth set power-on time. By pressing the CANCEL key 137, the input of the CANCEL key 137 is judged at step 41 and the process proceeds to step 42, where the display counter N RAM corresponding to
The data of the RAM address corresponding to the display counter (N + 1) is shifted to the address, the data of (N + 2) is sequentially shifted to the (N + 1), and the set power in the RAM address corresponding to the display counter N is turned on. Cancel time. Further, the mode is set to the 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, the display counter is reset and FLAG (CHECK) is reset, and the process returns to step 2 to read the next step input.

In the above description, if the data is not set in the RAM address corresponding to the display counter M in the judgment of step 37, the process proceeds to step 38 and the display counter is set to 1 and proceeds to step 39. This allows the user to
Each time the K key 136 is pressed, the set power-on time can be repeated successively to check on the clock display 139. In the first time, that is, when no data is set in the RAM address corresponding to the display counter 1, that is, when no power-on time is set, the display is blank.

In addition, the START key 13 is activated during either operation of (4) and (5) above.
By entering 5, step 33, or step 5
It is judged in step 1 that the mode being executed is terminated, the mode becomes the CLOCK mode, the display unit 129 is turned on, the current time is displayed on the clock display unit, and the next step input is read. Next, the operation of each mode set as described above will be described.

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

It is judged that all of the power-on times set in step 2 match the present time, and if they match, the process proceeds to step 3 to set FLAG (ON TIME). Then, the state of FLAG (ON TIME) is judged in step 16 and it is in the process of setting. Therefore, the process proceeds to step 17 to perform the same operation as the main switch 127 ON by the manual shown in the item (1), and the FLAG (ON TIME) ) Is reset.

(7) When the current time is the set power off time.

If all of the power-off times set in step 4 are judged to be the same as the current one, and if they match, the process proceeds to step 5. In step 5, the state of FLAG (OFF ALARM) is judged, and if the power-off by the timer control is not prohibited by the user during the setting, that is, the operation of item (8) (described later), proceed to step 6 and set FLAG (OFF TIME). Then, at step 20, FLAG (OFF TI
The state of ME) is judged and it is in the process of setting.
Go to 1. In step 21, the state of FLAG (OFF INHIBIT) is judged, and if it is in the process of setting, the process returns from step 25 to step 2 to delay the judgment OFF until FLAG (OFF INHIBIT) is reset. That is, in the data communication with the device controller 65 in the step 11 described in the item (1), the power-off by the timer control is delayed while the device controller 65 prohibits the power-off. When the power-off prohibition request from the device controller 65 is released, the process proceeds to step 22, which is a feature of the present invention. In step 22, it is determined whether the power is on within a predetermined time T ₁ and then T ₁ If less than 24
To FLAG without turning off the power relay (K1) 61.
Resets only (OFF TIME) and cancels power off by timer control. This is R at the current time and step 17
This is performed by comparing the time data stored in the AM when the power is turned on. This solves the inconvenience that the user manually turns off the power of the copying machine, and after the user turns on the power, the power is turned off by timer control before the user starts using the copying machine. If it is not within the time T ₁ , step 2
Proceed to step 3 and turn off the power relay (K1) 61 in the same way as when the main switch 127 was turned off by the manual operation, and the FLAG (MAIN
N) is reset and FLAG (OFF TIM
E) is reset and the operation is completed.

(8) To stop the power-off by the timer and the operation to display that the power-off time is approaching.

In step 7, it is judged whether or not the present time is before the set power-off time of each T ₂ and if they match, the process proceeds to step 8 and POWER OFF ALARM display 14
Turn on and set FLAG (OFF ALARM). This allows the user to know that the power-off time by the timer control is approaching. In this case, if the user wishes to continue the copy process, he / she presses "1" (ON) of the main switch 127 by a manual operation, and the step 12,
The program progresses with step 13 and the state of FLAG (OFF ALARM) is judged by step 14, and in this case, POWER
OFF ALARM is being displayed and the flag is set, so proceed to step 15. In step 15, the FLAG (OFF
ALARM) and then POWER OFF ALARM display 140
Turn off. As a result, even if the next set power-off time matches the current time and YES is determined in step 4, the FLAG (OFF ALARM) state is determined to be in reset in step 5 and the process proceeds to step 6. Without FLAG
(OFF TIME) is not set. Therefore, POWER OFF ALAR
By pressing the main switch 127 even when M is displayed, the power is not turned off by the timer.

In the present embodiment, the POWER OFF ALARM display 140 may be displayed by sound.

Further, although the time when the power is on and the time when the power is off are the same in the item (4), it is not necessary to make them the same. Also, in item (8), the setting time for displaying POWER OFF ALARM is set to T ₂ as in (4), but the setting time is not limited to this.

In this embodiment, the power on / off time or time set is described, but the present invention can be applied to the time or time set required for the automatic clearing of the number of sheets.

As described above, according to this embodiment, reservation control such as on / off of the power source can be easily performed on the operation panel of the copying machine. Further, since the number of copies input means can set the time or the time when the power source is turned on or off, no extra input means is required.

Further, since the power-off time or the like controlled by the timer can be delayed during the copy operation of the copying apparatus or within a predetermined time after the copy operation is completed (for example, during automatic clear), the power is suddenly turned off by the timer control during the copy operation. Can be prevented. Therefore, the user can avoid the trouble of making a copy again. Further, since the power supply is not turned off within a predetermined time after the copying operation is completed, the user can replace the original document and make a new copy. In addition, after turning on the power etc. by the manual operation, turning off the power etc. by the timer is stopped within a predetermined time.
It is possible to prevent the inconvenience that the power is turned off by the timer before the user manually turns on the main switch to perform copying.

Furthermore, according to the present embodiment, not only can the user be notified that the power-off time by the timer is approaching, but also when the user wants to continue using the copying apparatus, the main switch is turned on while displaying a notice such as power-off. By doing so, it is possible to prohibit the power off by the timer. Therefore, the user can continue to use the copying machine with a simple operation even when the power-off time is approaching.

Further, according to the present embodiment, when the time when the power source or the like is on or the power source or the like is off is shorter than the predetermined time,
Since the power on time etc. or the power off time etc. are prohibited, the user made a mistake in the time to set.
It is possible to prevent troubles by turning off the power immediately after the power is turned on.

Furthermore, according to the present embodiment, the power-on time by the timer,
Since a plurality of sets such as the power-off time can be set, the use time of the copying machine can be freely set according to the work. Moreover, since the set power-on time and the power-off time can be sequentially checked by a simple key operation, the time set by another person can be easily confirmed.
Further, since the power on time or the power off time can be displayed on the clock display, no extra space is required.

Therefore, the user has various troubles due to reservations such as turning on / off of the power supply (for example, the power is turned on during copying).
Since you can use the image reproducing device without being confused with
It is possible to eliminate waste of time due to miscopying or resetting of reservation time.

As described above, according to the present invention, when the off time stored in the storage means reaches the off time within a predetermined time after the power switch is turned on, the off time stored in the storage means is retained and the device is operated. The power supply to the apparatus is stopped to stop the power supply to the apparatus regardless of whether the image forming operation is being performed by the image forming unit thereafter, so that the operator can turn on the power switch for image reproduction. Even if the ON time is just before the reserved OFF time, for example, the power is turned off before the temperature of the fixing device of the copying machine has dropped and the temperature becomes copyable. If it takes time to select the originals or place the originals on the original placing table, the power will be turned off before pressing the copy button. , Power when returning to the copier where it is possible to prevent the occurrence of various inconveniences that are turned off after.

That is, the power supply is automatically turned off in a short time after turning on the power switch, and it is possible to prevent the troublesome operation of having to turn on the power switch again, thus improving the operability. it can.
