Abstract

PURPOSE:To prevent a battery from being wasted unwittingly because a power supply is left ON at the time of closing a display part when an information processor, especially a note type or lap top type personal computer or a ward processor e.g. whose display can be opened/closed is not used or carried as a portable device. CONSTITUTION:The lap top type or note type information processor whose display part can be opened/closed is provided with a sensor switch 10 capable of sensing the opening/closing of the display part from a body part and a power supply control part 13 having a program operation means 12 for receiving an open/close signal from the switch 10 and confirming the presence of program operation and capable of controlling power supply ON/OFF and driving a buzzer. Consequently the power supply for the device can be prevented from being left ON and the disconnection of the power supply during the operation of a program can be also prevented.

2. Description of the Related Art FIG. 4 is a block diagram of an example of a conventional information processing apparatus of this type, and FIG. 5 is an external view. In the figure, 1 is a lid-type display part of a liquid crystal display, 2 is a main body part that closes with the display part 1, and 3 is a manual power switch.

The operation of this conventional example is to open the display section 1 and turn on the manual power switch 3 during use. When not in use or when carrying the device, close the display section 1 and main body section 2 and turn off the power switch 3.

0004

[Problems to be Solved by the Invention] In this conventional information processing device whose display section opens and closes, the operator has to consciously turn the power on and off, and when the display section is closed when not in use or when carrying a mobile phone. There was a problem of forgetting to turn off the power and wasting the battery.

[0005] Also, when the display part is closed, the power is forcibly turned off.
For those with F mechanism, power is turned off while the program is running.
F or the power is turned off while accessing the disk device.
Therefore, there were problems such as destruction of the recording medium.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to prevent the operator from forgetting to turn off the power without making him/her aware of turning the power on/off, and to prevent wasted battery consumption. To provide an information processing device that can prevent a recording medium from being destroyed by turning off the power at any time.

[0007]

[Means for Solving the Problems] The information processing device of the present invention includes a sensor switch whose display section and main body detect opening/closing and transmits an opening/closing signal, and a sensor switch which receives the opening/closing signal of the sensor switch and controls the operation of a program. It has a program operation confirmation means for confirming the presence or absence of the program, and a power supply control section that controls on/off of the power supply and issues an alarm with a buzzer when the program is in operation.

[0008]

[Operation] In the information processing device of the present invention, the sensor switch senses the opening/closing of the display section and the main body and transmits an opening/closing signal, and the program operation confirmation means that receives this opening/closing signal confirms whether or not the program is operating. The power control unit turns on and off the power.
In addition to controlling the power off, a buzzer sounds an alarm when the program is running, so the power can be turned on and off automatically and safely.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be explained below with reference to the drawings.

FIG. 1 is a block diagram of an information processing apparatus which is an embodiment of the present invention. 10 is a pressure-sensitive sensor switch that sends a signal when the state of whether pressure is applied or released changes; 12
13 is a program operation check means for checking whether there is a program running when the display section 1 is closed; 13 is a power control section that has a program operation check means 12 and turns on/off the power according to a signal from the sensor switch 10; , 14
15 is a buzzer that emits an alarm when the program operation confirmation means 12 confirms the program in operation; 15 is a switch that is turned on and off by the power control section 13;

FIG. 2 is an external view of the information processing apparatus according to the present invention. Reference numeral 11 indicates a claw for applying pressure to the pressure-sensitive sensor switch 10, and other symbols are the same as in the conventional example.

FIG. 3 is a flowchart of the power supply control section of the present invention.

Next, the operation of the information processing apparatus of the present invention will be explained.

First, when the display section 3 changes from the closed state to the open state, the claw 11 sends an open signal from the sensor switch 10 which is remote from the pressure-sensitive sensor switch 10.
The program operation confirmation means 12 of the power supply control section 13 receives the signal and confirms that the sensor switch 10 is open (step ST50). Next, the power supply control section 13 confirms whether the power of the main body section 2 is ON (step ST51). ), if it is OFF, turn on the power switch 15 (step ST5
2).

Next, when the display section 1 is closed from this state, the claw 11 applies pressure to the pressure-sensitive sensor switch 10, and the sensor switch 10 sends a press-down close signal, and the power supply control section 1
3 receives the signal (step ST50), checks whether there is a running program by the program operation checking means 12 (step ST53), and if there is no program (step ST54), turns off the power switch 15 (step ST55). ).

Further, if there is a program in operation (step ST54), the buzzer 14 will sound and the power will not be turned off (step ST56).

Then, the operator opens the display section 1 again with the buzzer's warning sound, performs the program termination process, and closes the display section 1 again, so that the claw 11 is activated by the pressure-sensitive sensor switch 1.
Apply pressure to 0 and send a press-down close signal,
performs the above-mentioned processing and the power is turned off. When you close the display in this way, the device will automatically turn off.
Also, interruption of running programs can be avoided.

[0018] In the above explanation, as an example, the claw 11 and the pressure-sensitive sensor switch 10 are used as the sensor switch that detects the opening and closing of the display section 1 and the main body section 2, but the present invention is not limited to this. , a similar effect can be obtained if it is possible to recognize whether the opening or closing is detected by light, and the object of the present invention can be achieved.

[0019] Also, as a program operation confirmation means, the OS
A similar effect can be obtained and the object of the present invention can be achieved by any means that can confirm whether or not a program is running using job management information.

[0020]

[Effects of the Invention] As is clear from the above explanation, according to the information processing device of the present invention, in a device whose display section opens and closes, the operator does not have to be conscious of turning the power ON/OFF, and the information processing device can be used easily when not in use or when being carried. When the display section is closed during transportation, it is possible to prevent forgetting to turn off the power, prevent wasteful consumption of the battery, and prevent destruction of the recording medium by turning off the power during program operation.
