It is discriminated whether the current time is a time T2 before all set power-off times or not; and if the current time coincides with a set power-off time, a POWER OFF ALARM indication 140 is turned on, and a FLAG (OFF ALARM) is set.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to reservation control of power supply, etc. of a post-playback device.

Conventionally, the power of a copying machine has been turned on and off manually by the user; in an office, etc., the user turns on the power switch first thing in the morning, and the final user or full-time administrator turns it off at the end of the day. was. Therefore, people often forget to turn on or turn off the switch, which leads to inconveniences such as wasting power, and when attempting to make copies during regular work, the power is turned off and time is lost. In order to solve these problems, conventional methods have been developed such as an auto-shut-off function that automatically turns off the power after a certain period of time after the copy process is completed, or a pressure fixing device to eliminate wait time. In the latter case, the auto-shutoff time is fixed, making it difficult to use for some types of copying machines, and in the latter case, problems with fixing properties have been a problem for use in high-speed copying devices.

Therefore, a copying machine has been proposed in which a power-on time and power-off time can be reserved.

However, if the operator sets a reservation while waiting to start the next image playback after performing one image playback, and the power supply off time arrives, the next image playback cannot be performed. This is inconvenient and causes poor operability.

The present invention has been made in view of the above points, and eliminates the inconvenience of turning off the power supply using a timer, notifying the operator that the time to turn off the power is approaching, and continuing image reproduction. It is an object of the present invention to provide an image reproducing apparatus which can prohibit turning off of the power supply set in advance if desired, and which can improve operability.

That is, the present invention provides a power supply means for supplying power to the device, a clock means for outputting time information, a setting means for setting a desired off time at which the power supply to the device is turned off, and a method determined by the setting means. a storage means for storing an off time at which the device is set; and a storage means for storing an off time stored in the storage means and time information outputted from the timekeeping means, and when they match, the power supply to the device by the power supply means is turned off. A control means, when the difference between the off time stored in the storage means and the time information output from the time measurement means becomes less than a predetermined time, notifies that the time to turn off the power supply to the device is approaching. and an operating means for inputting a signal for prohibiting the power supply from being turned off only once by the control means, and the control means is stored in the storage means after being notified by the notification means. If there is an input from the operating means before the first OFF time in terms of time, power is supplied to the device at the first OFF time in terms of time while the OFF time stored in the storage unit is maintained. To provide an image reproducing device characterized in that the turning-off operation of the image reproducing device is prohibited only once, and the power supply to the device is not prohibited from being turned off even if an input is received from the operating means before the notification is given by the notifying device. The purpose is to

FIG. 5 shows a set of flags used in the general flow chart of FIGS. 4-a to 4-c,
This is a list of reset conditions.

Next, with reference to Figures 2, 3, and 5,
The general flowcharts shown in Figures -a to 4-c will be explained. When the plug 51 is inserted into a power outlet or the backup power supply 53 is connected to the clock controller 56, the clock controller 5
The microcomputer (hereinafter referred to as microcomputer) in 6 starts operating and executes a program as shown in the flowcharts of FIGS. 4-a to 4-c. First, in step 1 of Fig. 4-a, the RAM in the clock controller 56 is initialized, the display on the operation section (A) 58 is set to the CLOCK mode display, and the line is set to display 00:00 on the clock display. Data is output to the display driver 57 through L2.

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 repeats the clock timer data up every minute.

At this stage, the copying machine's power relay (K1) 6
1 has not yet been turned on, all the indicators of the operation section (B) 67 remain off.

Next, the main switch 12 is turned on by manual operation.
The operation when 7 is turned on and off will be explained.

(1) When the main switch 127 is turned on by manual operation Following Step 1 above, in Step 2, Step 4, and Step 7, it is determined whether the time is the timer-controlled power-on time, power-off time, or power-off notice start time. to decide. In this case, since the plug 51 has just been inserted, the time has not been set for any mode, so proceed to step 9 and proceed to the operation section.
The status of the switch on (A) 58 and the status of the numeric keypad 105 and clear key 106 on the operation unit (B) 67 are input to the timepiece controller 56 through line L4 and set in the RAM. Then in step 10
The status of FLAG (MAIN ON) is determined, but it has not been set yet at this stage, so we will skip the steps.
Proceed to 12. In step 12, check the key input data in the RAM and turn on the main switch 127.
It is determined that 1” (ON) has been pressed, and the process proceeds to step 13, but at this stage FLAG (MAIN
ON) has not been set, so proceed to step 17 and immediately turn on the power relay (K1) 61.
Stores the on time in RAM. Also FLAG
(MAIN ON) and turn main switch 1.
27 is turned on. Furthermore, FLAG
(ON TAME). FLAG(ON
TIME) will be explained in Section 6 below. Next, in step 18, the main switch 127 is turned on by checking the key input data in the RAM.
It is determined that "0" (OFF) is not pressed, and the process proceeds to step 20, where it is determined whether FLAG (OFF TIME) is set, but since it is not set at this stage, the process proceeds to step 25.Step 25 Next, 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 the copy mode, the process returns to step 2. First, the case where the copy mode has been selected will be explained.

In step 2, step 4, and step 7, the judgment is still NO, so in step 9, the state of the switch on the operation section (A) 58 and the operation section (B) are checked again.
The state of the numeric keypad 105 and clear key 106 on the 67 is read and the data is set in the RAM, but at this stage it is assumed that none of the switches are pressed. The process moves to step 10 belatedly, but at this stage, since FLAG (MAIN ON) has been set, it is determined that the power relay (K1) 61 of the copying device is turned on, and the process proceeds to step 11, where the communication with the device controller 65 is established. Data is exchanged between the two. Regarding the data here,
From the clock controller 56 to the device controller 6
5, the status of the numeric keypad 105 and clear key 106 is sent to the clock controller 56, and the clock controller 56 receives data on various statuses of the copying machine from the device controller 65. If the copying device is in the process of copying, or within a predetermined period of time after the copying operation has ended (for example, during the auto clear time), the FLAG
(OFF INHIBIT) and reset when the inhibition is lifted. Next, proceed to step 12 again, but in this case, switch the main switch 127 to 1".
(On) is not input, so proceed to step 16.
The state of FLAG (ON TIME) is determined, but since it has not been set yet, proceed to step 18. After step 18, the process proceeds to step 20 and step 25 in the same manner as described above, and until the switch 128 switches to the time set mode, the process continues by determining whether the times match in step 2, step 4, and step 7. , the state of the switch is read in step 9, and in step 11 the clock controller 56 continues to communicate data with the device controller. Of course, the microcomputer's internal timer continues counting in parallel with the above steps, continues counting time from the initial state of the clock set in step 1, and updates the clock display 139 every minute.

(2) When the main switch 127 is turned off by manual operation, the main switch 127 is
0” (off) input is set in RAM, the data is determined in step 18, and the data is determined in step 19.
Go to , turn off power relay (K1) 61,
FLAG (MAIN ON) is reset to remember that the copying machine's power has been turned off, and in steps 10 and 11, data communication with the machine controller 15 is prohibited.

Next, the time set mode will be explained.

(3) When setting the time in CLOCK mode, first switch the switch 128 from copy mode to time set mode, then in step 9 the state is read and data is set in RAM, and then the program proceeds. step 25
When the mode is reached, the mode is determined here, 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 (A) 58 and the numeric keypad 105 and clear key 106 on the operation unit (B) 67, the determinations in step 26, step 28, step 30, step 32, and step 33 are all ON. Step 34 is YES, so step
Proceed to step 39 and judge FLAG (CHECK), but since it has not been set yet at this stage, return to step 2 and repeat from the start of the above 3. Also, to explain the case in which the user inputs 12:30 using the numeric keypad 105 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. is determined to be input using the numeric keypad, the process advances to step 29, and the display 139 shows 00:01.
Display. In the same way, 2, 3, 0 are read and the display 139 shows 00:12, 01:23, 12:30.
are displayed sequentially. Next, when the user presses the START key 135, the data set in the RAM in step 9 is determined in step 33, and the process proceeds to step 43. In this case, since the mode is CLOCK mode, the process proceeds to step 44. And display 13
Since the numerical value displayed above 9, that is, the numerical value set by the user, has already reached 4 digits, the process proceeds to step 45, where it is determined whether or not it is ON TIME mode, but since it is NO, the process proceeds to step 47.
In step 47, it is determined whether or not it is OFF TIME mode, but since it is NO, proceed to step 49.
Indicated by display counter in CLOCK mode
Store a 4-digit number to a RAM address. The display counter will be explained in Section 4, but
In CLOCK mode, since multiple time sets are not possible, the display count always remains 0, and the time data in the RAM address represented by display counter 0 in CLOCK mode always represents the current time. The internal timer continues to add the time every minute. Next, the process advances to step 50, where the numerical data on the temporary memory for numeric key input is cleared, and the time set on the display 139 starts counting as a clock display. Furthermore, FLAG
(CHECK) is reset, but in the CLOCK mode, FLAG (CHECK) is never set, so this 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 up to 3 digits were input.
If the START key 135 is pressed, the process goes to step 51 because 4 digits of numerical data have not been entered in step 4.
Since there is an input from the key 135, the process advances to step 50. In this case, step 49 was skipped, so new time data is not set in step 50, and the old time that was being counted is displayed on the display.
It appears in 39.

(4) When setting the power on time or power off time in ON TIME mode or OFF TIME mode, the setting method is the same for both power on time and 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 TIME mode key, and the process proceeds to step 31. In step 31, the ON TIME mode indicator 130 is lit,
The time of day is displayed on the display 139. This is to clear the data on the temporary memory for numeric key input that was in the middle of setting when another time was being set, and to enable the power-on time to be set. Next, as in Section 3,
The numerical data input to the RAM in step 9 is judged in step 28, and in step 29 the 4-digit data is displayed on the clock display 139, and then the SET key 1 is pressed.
38 is input, it is determined in step 32 and the process proceeds to steps 44 and 45. In step 45, it is determined whether the ON TIME mode is enabled or not. In this case, it is the ON TIME mode, so proceed to step 46.
Determine whether there is T ₂ or more, and if it is T ₂ or more, proceed to step 49 and turn on the power on time and specified data on the temporary memory for numeric key input.
RAM indicated by display counter in TIME mode
Store to address. However, if there is no power off time that has already been set, proceed to step 49 unconditionally.
Proceed to. In the OFF TIME mode, the above judgment changes to step 47 and step 48, and similarly, the power-on time at the time of setting and the power-off time data in the temporary memory for numeric key input entered this time are used. It is determined whether there is a difference of T ₂ or more. As a result of the above, the time between the power on time and power off time due to time control is a certain amount of time.
This avoids the inconvenience of the copying machine being turned off immediately after _being turned on due to an error in setting the power on time or power off time under timer control.

To explain the display counter here, when storing the power on time and power off time in the order set by the user in the power on time or power off time storage area in RAM, the display counter is assigned to that address. .
In other words, if three power-on times are set, display counters 1, 2, and 3 are assigned in the order in which they are set, and the CHECK key 13 is assigned.
The set power-on times are sequentially displayed on the display 139 according to the number of inputs in step 6. Therefore, if a fourth power-on time is set, it will correspond to 4 on the display counter.
It is stored at a RAMT address.

Next, the process proceeds to step 50, where the numerical data on the temporary memory for numeric key input is cleared, the mode is set to CLOCK 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.When up to 3 digits are input, press the SET key
If is pressed, step 44, step 51
The input of the SET key 138 is invalidated. However, in this case, the three-digit numerical data that has been input up to that point is retained as is, and it is possible to continue inputting the fourth digit. After entering 3 digits again, the previous 3
If you want to clear the digit input, press clear key 10.
By inputting 6, it will be judged in step 26,
In step 27, the numerical data entered up to that point on the temporary memory for numeric keypad input is cleared, the mode is set to CLOCK mode, and display 1 is cleared.
30 is turned off and the display 129 is turned on.

Furthermore, if the difference between the power on time and the power off time is less than a certain time _T2 , the numerical data on the temporary memory for numeric keypad input will not be cleared.
Since the mode is not set to CLOCK mode, 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) Since the ON TIME mode and OFF TIME mode are the same when confirming and canceling the set power on time (or power off time), only the ON TIME 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 item 4. Next, it is determined in step 30, and in step 31, the display 13 of the ON TIME mode is selected.
0 is lit and the time is displayed on the clock display 139. Next, when the CHECK key 136 is pressed, it is determined in step 35 and the process proceeds to step 36.
Proceed to. In step 36, FLAG(CHECK)
Set. From now on, the check in ON TIME mode will be stored until FLAG(CHECK) is reset. At the same time, the numerical data in the temporary memory for numeric keypad input is cleared, and the same mode (in this case, ON) is cleared.
Clears the numerical data when the time is in the middle of setting in TIME mode). Furthermore, the display counter is incremented. The display counter is
If the CHECK key 136 is pressed for the first time,
Since it is 0 in the state after reset, it becomes 1 here. Next, in step 37, if the data in the RAM address corresponding to display counter 1 has been set, proceed to step 39, and press FLAG (CHECK).
is set or not, that is, ON
Determine whether or not the check is in TIME mode, and turn ON when FLAG (CHECK) is reset.
If it is not a TIME mode check, return to step 2, but in this case, immediately after the CHECK key 136 is pressed, FLAG (CHECK) is being set, so proceed to step 40 and check the data at the RAM address corresponding to display counter 1, that is, set. The completed power-on time is displayed on the clock display 139, and the process advances to step 41. In step 41, it is determined whether or not the CANCEL key 137 has been pressed, but since it has not been pressed at this stage, the process returns to step 2 and reads the next CHECK key input. If there is no CHECK key input by the user, NO is determined in step 35, and the process proceeds to step 39 and step 40, where the RAM corresponding to 1 on the display counter is displayed.
The data within the address continues to be displayed on the clock display 139. Next, the user presses the CHECK key 1 again.
If 36 is input, proceed to step 35 and step 36, increment the display counter, and
2, it is determined in step 37 whether or not data is set in the RAM address corresponding to display counter 2. If data is set, the process proceeds to step 39 and step 40, and the data is set in the RAM address corresponding to display counter 2. The data within, that is, the second set power-on time is displayed on the clock display 139. If the user repeats the same operation N times and wants to cancel the Nth set power-on time, press the CANCEL key 137.
The input of is judged, and the process advances 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 (N+2) is sequentially shifted to (N+1). Then, the set power-on time in the RAM address corresponding to the display counter N is canceled. 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, the display counter is reset.
Reset FLAG (CHECK) and step 2
Return to 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 press the CHECK key 136
Each time the button is pressed, the set power-on time can be checked repeatedly on the clock display 139. Also, the first time, that is, display counter 1
If no data has been set in the RAM address corresponding to , that is, if no power-on time has been set, the display will be blank.

Also, during the operation of either item 4 or 5 above,
By inputting the START key 135, the mode that is being executed as judged in step 33 or step 51 ends, and the mode changes to CLOCK mode.
29 is turned on and the current time is displayed on the clock display in preparation for reading the next switch input. Next, the operation of each mode set as described above will be explained.

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

In step 4, it is determined that all of the power off times set coincide with the current time, and if they match, the process proceeds to step 5. In step 5, the state of FLAG (OFF ALARM) is determined, and if the user has not prohibited the power off by timer control during setup, that is, by the operation in item 8 (described later), the process proceeds to step 6.
Set FLAG (OFF TIME). Then, in step 20, the state of FLAG (OFF TIME) is determined, and since setting is in progress, the process advances to step 21. In step 21, FLAG (OFF

(8) An operation that indicates that the timer-based power-off time is approaching, and when the timer-based power-off is canceled.

In step 7, it is determined whether the current time is before _T2 of all the set power off times, and if they match, proceed to step 8.
Go to , turn on the POWER OFF ALARM display 140, and set FLAG (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, he/she can manually switch the main switch 12.
Step 12 by pressing 〓1'' (ON) in 7.
The program progresses to step 13, and the status of FLAG (OFF ALARM) is determined at step 14. In this case, the POWER OFF ALARM is displayed and the flag is set, so the step is stopped.
Proceed to step 15. In step 15, in order to skip the data of the next scheduled power off time,
Reset FLAG (OFF ALARM) and
Turn off the POWER OFF ALARM display 140. This will ensure that the next set power off time matches the current time and will be turned off in step 4.
Even if the answer is YES, at step 5
The state of FLAG (OFF ALARM) is judged to be resetting, and the FLAG is reset without proceeding to step 6.

By pressing the main switch 127 even while the POWER OFF ALARM is displayed, the power supply will not be turned off by the timer.

In addition, in this example, POWER OFF
The ALARM display 140 may be displayed with sound.

Furthermore, in Section 4, the time when the power is on and the time when the power is off are made the same, but it is not necessary to make them the same. Also, in Section 8,
The setting time when performing the POWER OFF ALARM display is set to T ₂ as in Section 4, but there is no need to limit it to this.

Although the present 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 automatic clearing of the number of sheets.

As described above, according to the present 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 number of copies input means allows the time or time of turning on/off the power source, etc. to be set, no extra input means is required.

Furthermore, while the copying device is in the process of copying or within a predetermined period of time after the completion of the copying operation (for example, during auto-clearing), the power-off time can be delayed by timer control. can be prevented. Therefore, the user does not have to make copies 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 the power is turned on by manual operation, the timer is prohibited from turning off the power, etc. within a predetermined period of time after the power is turned on by manual operation. It is possible to prevent inconveniences such as the occurrence of turning off.

Furthermore, according to this embodiment, not only can the timer notify the user that the power-off time is approaching, but if 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 a predetermined time, setting of the power on time, etc. or power off time, etc. is prohibited. Therefore, it is possible to prevent troubles such as when the power is turned off immediately after being turned on due to the user setting the wrong time.

Furthermore, according to this embodiment, it is possible to set a plurality of power on times, power off times, etc. using a timer, so 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 easy to 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). It is possible to avoid wasting time due to resetting.

As explained above, according to the present invention, in the middle of image reproduction, the operator can know that the power off time is approaching, and if he wants to continue image reproduction, he is prohibited from turning off the power supply according to the reservation setting. It is possible,
Operability can be improved. Therefore, for example, if the operator has performed one image reproduction and is taking time to start the next image reproduction, and the scheduled power supply off time has come, the next image reproduction cannot be started. This will prevent the inconvenience of not being able to do so.

Furthermore, even if a signal for prohibiting turning off the power supply is input before the power supply off time approaches, it is possible to prevent the power supply from being inadvertently prohibited.

Further, even if turning off the power supply is prohibited, the off time stored in the storage means is retained, so that the power supply can be easily turned off at the same time the next day.
