Abstract

PURPOSE:To prevent the operator's misoperation of a power supply switch and to improve the operating efficiency by turning off the power supply of an information processor by only selecting the icon displayed on a display device. CONSTITUTION:An MPU 3 has no operation and is reset to a state set before an interruption even in case the switch of a PSW is turned on and off and the signal inversion NMi is produced at the MPU 3 via an edge detecting circuit and an FF 14. Thus the power supply is not turned off despite the push of the switch of the PSW. Then the power supply is turned off in such a case where a mouse 6 is shifted when the power-off icon PiCON is selected to shift a cursorup to the PiCON and a switch K of the mouse 6 is pushed. When the PiCON is not selected, the hitherto document processes are continued. Then an open file is closed through a disk 7 to complete the access to the disk 7 when the PiCON is selected. Then a command signal is supplied to a decoder 11 and the power supply is turned off.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device that is configured with an input device, a display device, an MPU, etc. and performs information processing, and particularly relates to a device that controls power on/off of the device by a program. This relates to an information processing device that can.

[Conventional technology]

Conventionally, the power of information processing equipment is managed by the MPU using software, and in order to prevent the power from being turned off immediately even when an operator turns off the power switch of the information processing equipment, the MPU detects that the power switch is turned off. The power was turned off after the device had finished processing.

[Problem that the invention seeks to solve]

However, even in this case, the power is turned off after the operation is completed under the control of the MPU, so for the operator, the power is turned off even when information processing is in progress, and the operator may accidentally turn off the power switch. If you turned it off, you had to turn it back on and redo the process.

[Means for solving problems]

A display means for displaying an icon for instructing to turn off the power; a cursor displayed on the display means and movable on the display screen; a cursor moving means for moving the cursor; The problem lies in the instructing means for instructing the output of a signal instructing to turn off the power when the icon displayed on the display means is located at the position of the icon instructing to turn off the power. It is a means to solve a problem.

[For production]

Power the cursor by means of cursor movement.

When the icon is moved to an icon for instructing to turn off and the instruction means outputs a signal to turn off the power, the control means receives this signal and turns off the power. The present invention will be described in detail based on the following.

FIG. 1 is a block diagram of a document processing apparatus according to an embodiment of the present invention. In the figure, the reference numeral 1 is a high-resolution bitmap display device, which displays V under the control of an MPU 3.
The image information developed in the RAM 2 is displayed. Reference numeral 4 denotes a keyboard, and by operating the keys on the keyboard, various operations, ie, document processing such as inputting a single sentence and editing a document, are performed. Furthermore, by pressing the mouse switch K, the user can instruct selection of a process. In addition, RAM5 consisting of volatile memory is provided, and this RAM
On the M5, document data displayed on the CRTI or document data read from the storage device Disk7 is developed.

Reference numeral 8 denotes a ROM, which includes a program area PE that stores a program for executing document processing under the MPU 3 and a control program according to the flowcharts shown in FIGS. It has a menu screen area ME in which menu screens to be displayed are stored.

Reference numeral 9 denotes a power supply device whose power on/off is controlled by the MPU 3.

Next, FIG. 2 is a configuration diagram of hardware related to power on/off according to an embodiment of the present invention. first(
A) is the hardware for the MPU3 to detect the on/off state of the power on/off switch PSW.When the PSW is turned on/off, the rising edge is detected by the edge detection circuit, and the flip-flop circuit 14 is used to detect the rising edge at J-. Generates non-maskable interacted N1γ go and MPU3
interrupt.

When MPU 3 receives N]J]-, FCO.

FCl, FC2, and 7V''g become high, an interlaced ACK rττ is generated, and Tv is cleared.

When an interrupt is applied to MPU3, the MP
Control of U3 is transferred. In addition, (8) is the hardware for turning off the power from the MPU 3. When the MPU 3 writes specific data to a specific address, the specific data is recognized by the decoder, and the COMMAND address selected by the specific address is is latched by the D flip-flop R circuit and turns FPOFF.
A signal is generated. This FPOFF signal is the driver 13
is applied to the power supply device 9 via the power source 9, thereby turning off the power.

Next, the operation of this embodiment will be explained with reference to the flowcharts in FIGS. 3(a) and 3(b). In this embodiment, as shown in step S1, the PSW is turned on and off. .

N to MPU3 via the hardware shown in Figure 2 (A).
Even if an MI occurs, the MPU 3 does nothing and returns to the state before being interrupted.

In other words, the power is turned on even if the PSW switch is pressed, and the switch K of the mouse 6 is pressed.

If no selection is made in S10, the document processing up to that point is continued in step Sll.

If selected, in step S12 all open files from the disk 7 are closed, access to the disk 7 is terminated, in step 513 the CRT 1 screen is cleared, and in step S14 the second CRT screen is cleared. The document processing apparatus is powered off via the hardware shown in FIG. 3B, that is, by setting an address in the decoder and inputting a command signal.

In the above description, the information processing apparatus is a document processing apparatus, but it goes without saying that the present invention is also applicable to information processing apparatuses that process image information and other information.

〔effect〕

As explained above, according to the present invention, by turning off the power of the device only by selecting the icon displayed on the display device, it is possible to prevent the operator from erroneously operating the power switch, thereby improving operational efficiency. An information processing device capable of achieving this can be provided.
