Abstract

PURPOSE:To simplify setting time of turning on and off a main electric power supply, by providing time setting means both attachable and detachable capable of optionally setting a time for turning on and off the power supply. CONSTITUTION:Digital switches A, B and C, D are used for turning on and off a power supply, time is divided into a.m. and p.m., and selected with toggle switches MSA, MSB. Each o'clock and each 5min are selected in accordance with times of depression of microswitches MS1, MS2, each o'clock for switches A, C and each 5min for switch B. When the watch in a copying apparatus coincides with the time of the power supply to be turned on, an H level signal is transmitted from the terminal 1 of the output port PC of CPU to turn on a main power supply switch SW1. On the contrary, when it coincides with the set value of the power supply to be turned off, SW1 is turned off by providing an H level signal from the terminal 2. When the time setting device is detached from the main body, remote control of the main power supply is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying machine that automatically turns on and off the machine power at a desired installation time. There are some that have power saving functions. For example, there is an auto-shutoff function that automatically turns off the power after a predetermined period of time has passed after the copying operation is completed. However, the conventional auto-shutoff function turns off the power after a predetermined period of time after the copying operation is completed, and the power is turned off at the user's desired time.
Processing to turn on or turn off FiO was rarely performed.

To solve this problem, a device has been devised in which the desired power control time is set using operation s on the copying machine, but f! The configuration of the device is complicated, the settings are complicated, and power supply control is not required - the user also has to make complicated installations.

The object of the present invention has been achieved in view of the above points.

Used on a removable time setting device.When time control is required, the time can be set with a simple operation by loading it into the device.Furthermore, when the time setting is not required, this time setting can be done. By removing the device, the time control function is eliminated, making it easy to operate.

The electrostatic latent image on the photosensitive drum 1 is then developed by the developing roller of the developing device 7 and visualized as a toner image, and the toner image is transferred to the transfer paper by transfer charging.

The transfer paper in the upper cassette 13 or the lower cassette 14 is fed into the transfer machine by the paper feed roller lit or 12, and is sent in the direction of the photosensitive drum 1 with accurate timing by the registration roller 15, and is then transferred onto the drum 1. The leading edge of the latent image can be aligned with the leading edge of the transfer paper at the transfer section.

Next, while the transfer paper passes between the transfer charger 5 and the photosensitive drum l, the toner image on the photosensitive drum l is transferred onto the transfer paper.

After the transfer is completed, the transfer paper is separated from the photosensitive drum l by a separation belt and conveyed via a paper detection sensor 16 to a conveyor belt) 17
At the end of the day, the foot is guided by rollers 19.

The paper is fixed by pressure and heating, and is then ejected to the tray 31 by the ejection roller 42 via the paper detection sensor 18. In addition, if the sorter 46 is installed, each tray KtlF is outputted from the sorter 46C via the line paper detection sensor 47'l.

Further, numeral 29 is a good conveyance fan that reliably conveys the transfer paper. 20 is a nib for cleaning after fixing. After the transfer, the photosensitive drum 1 continues to rotate, and is cleaned and collected by a cleaning device 6 consisting of a cleaning roller and an elastic blade.Good toner is discharged through a pipe 45 to a toner container 43.

Furthermore, in FIG. 4i, digital switches A and B are used to set the power ON time, and switch CD is used to set the power OFF time. The times are 11 a.m. and p.m.
Select the toggle switch M8 and MSB separately, and use the digital switch to select 1 o'clock in 1 hour increments from Cao to 11 o'clock, and switch B and D to select in 5 minute increments from 0 to 55 minutes. Select "@minute".

A circuit having a clock function is incorporated in the copying machine to turn on and off the main power of the copying machine at the 9th hour specified by the time setting device 8. Returning to Figure 3, based on the minute-by-minute O signal that is frequency-divided from the basic clock in the CPU, it is calculated to display the entire current time, and the time data is sent from the output capo-PI to the display T. As shown in Figure 1, it is displayed at 1:00 and "1 minute". In the initial state WI of the copying machine, the operation of setting the time of this clock circuit is performed by the microswitches MSI and M82. In other words, when the switch MSI is pressed for the first time, the TO@hour display on the evening display blinks. Thereafter, each time the switch M82 is pressed, the "hour" can be changed by t+1. 1 o'clock" is displayed from 0 to
It appears to be rounded by 23. Next switch MSI
By pressing , the @ minute “O1!” indicator will blink.

From then on, each time the switch MS2 is pressed, @minute'' can be changed by +1.The display Fio of ``minute'' can be changed by +1.Finally, when the switch M81 is pressed, the control unit Q
detects this as the end of time setting, and at the same time the clock starts one.

By controlling the time control of the main power supply as described above, the clock in the copying machine is turned ON when the power in the time setting device S is turned ON.
If it matches the setting value of CPU t! After determining this, the control unit 1sQ outputs a HI level signal through terminal 1 of the PC and turns on the main power switch 5WIt-ON. Conversely, if it matches the power OFF setting value, the output boat PC

Furthermore, the time setting device St is removed from the main body, the signal B appearing on PH, the pull-up resistor group Rn connected to VecK, and the HI level at eclipse from K. control!
By inputting this signal, the IQ determines that the user desires time control of the power source to be 1 kvh, and prohibits the remote control of the main power source.

Hereinafter, further explanation will be given according to the o, 1st 1st flowchart. °The first time to plug in the power supply of the device/
When the clock is inserted into the set/set, it is initialized by the control 1s QU power-on reset signal, and the clock is first started in step S1. Determine whether or not O is present.

A flag indicating that the evening hour hand is being set is set by the first MSI input, and the process proceeds to step 813 to determine whether the clock setting has been completed.If the setting is not completed, the process proceeds to step 814.
The display blinks and the process returns to step S2. During the time setting in step 82, from step S9 to step 81
Proceed to G and determine whether switch M82 is powered by human power. Flow is 1 o'clock" Switch MS2 for setting the numerical value When human power is detected, the following steps 811 to 8
Advance by 12K and set the displayed value 'j-+1 at @hour'.Then, step Ssg8@eSl.~8xsk are repeated to complete the setting to the desired number.

Furthermore, in step S9, when the input of the step Ma1 is detected again, the setting of "minutes" begins. In this case as well, set "1 minute" at 70-, which is the same as the "hour" setting. Then, in step S9, when all the last 0M5I inputs are detected, the clock setting flag is reset, and step 813
1: It is determined that the time setting is completed, and the process returns to step 81. In step 81, the nine clock meeting is restarted according to the standard time. As the time setting is completed in the following step S2, the process proceeds to step 83 and the main power is turned on.
- Query the time setting device S via the output port (PGt) for the OFF power setting time, and read the return signal from the input port (PH). In step S4, it is determined whether the levels of the return signals are all HI. If all the levels are HI and 1 kff, it is determined in step S5 whether or not the clock time is within the main power ON setting period. If the main power ON time is met, the main power switch 5WIION is turned on in step 87 and the process proceeds to step 811. If the condition is not satisfied, step S
6, turn off the main power switch 5W1t, and step B9
Go forward fC. Furthermore, if the level of all the return signals is HI in the determination in step 84, it is determined that the power supply O time control is prohibited, and l! <Step 85, 8

Bypass 87.絖〈〈〈70〉Since no operation has been performed, the process advances from steps 89 and 810 to step 15, and the main power supply of the copying machine is turned on and off.
- Discrimination is made using the divided voltage potential -1 from the human cover PD. If the main power is OFF, the process returns to step 2; if the main power is ON, the process proceeds to step 816. In step 16, it is determined whether or not a copy operation key has been input. If there is an input, one service corresponding to the key human power is performed in step 817, and the process returns to step S2.

If the microswitch MS2' is operated without passing through the normal operator l1lIt-, the process returns from step 811 to step 82.

As described above, according to the present invention, the main power ON/OFF time control of the copying machine can be performed by a simple time setting operation, and furthermore, since this time setting device is removable, when one time control is not performed, Therefore, it is possible to provide a copying apparatus that is easy to operate by simply removing the power installation device.
