Abstract

PURPOSE:To avoid the cut-off of a power supply in an unfinished state by cutting off no power supply instantaneously when a power supply switch is turned off but after a working job is through. CONSTITUTION:A power supply cut-off control system consists of a power supply main control part 1, a power supply monitor part 2 for a power supply switch 21, a function key monitor part 3 for a function key 23, a monitor part 4 for power supply cut-off command, a job control setting part 5, a job action monitor part 6, a display part 7 for busy mode of a CRT, and a power supply part 8. The part 1 includes various tables 11-15 and a power supply control part 16. Thus, a power supply switch table 11 stores the ON/OFF state of the switch 21, a function key table 12 stores the push state of the key 23, and a power supply cut-off command table 13 stores the presence or absence of reception of a power supply cut-off command. Other tables 14 and 15 also work for storage respectively. The part 16 monitors the states of those tables and judges the cut-off of the power supply.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Use] The present invention relates to a power-off control method, and particularly to a method for controlling power-off in an information processing device by program control.

[Conventional technology]

Conventionally, power-off control methods for information processing equipment, especially medium-sized to small-sized information processing equipment and terminal devices, have been used to check whether the processing (job) in this device has been completed by turning off the power switch of the device that has been powered on. The mainstream method was to be able to turn off the power regardless of whether or not the power was turned off.

[Problem that the invention seeks to solve]

In the conventional power-off control method described above, when the power switch is turned off, the power is cut off regardless of the operating state of the device. If so, its processing (job)
The problem is that the process is interrupted in a half-finished state (the process is not completed), and subsequent repair processing cannot be performed or that it takes a long time. In particular, with devices that can run multiple processes (jobs) simultaneously on a single gW, which is now becoming mainstream, it is difficult to judge whether all processes (jobs) have finished when the power switch is turned off. Since it is difficult, the above-mentioned drawbacks become noticeable.

In view of the above-mentioned points, an object of the present invention is to provide a power cut-off control method that does not immediately cut off the power when the power switch is turned off, but allows the power to be turned off after waiting for the completion of the operation of the currently running job. Our goal is to provide the following.

[Means for solving problems]

The power cut-off control method of the present invention includes a power switch state storage means that stores the on/off state of the power switch, and a pressed state of a function key that enables the power to be cut off by being pressed at the same time as the power switch is turned off. function key state storage means for storing, power-off command reception/non-reception storage means for storing whether or not a power-off command has been received, and job monitoring state storage means for storing whether or not a running job is to be forcibly terminated. , job operation state storage means for storing the operation state of jobs in the apparatus, and a power supply control section for monitoring the states of these means and determining whether to turn off the power.

[Effect]

In the power cut-off control method of the present invention, the power switch state storage means stores the on/off state of the power switch, and the function key state storage means is pressed at the same time as the TL power switch is turned off, thereby making it possible to turn off the power. The pressed state of the function key is memorized, the power off command reception/non-reception storage means memorizes the presence or absence of the TL power off command reception, and the job monitoring state storage means memorizes whether or not to forcibly terminate the running job. , the job operation state storage means stores the operation state of the job in the apparatus, and the power supply if, II
The controller monitors the states of these storage means and determines whether to turn off the power.
