Abstract

PURPOSE:To perform control so as to keep the off state of a power source in spite of the execution of key input in a state where a protective panel is closed. CONSTITUTION:A system controller 6 regulates an operation to control a power source controller 5 in an on-state while a protective panel opening/closing detection switch 3 detects the closed state of the protective panel 1 by providing the protective panel opening/closing detection switch 3 which detects the opening/closing state of the protective panel 1 to protect information equipment by covering a keyboard 9 when it is not used, and inputting the detection output of the protective panel opening/closing detection switch 3 to the system controller 6. Therefore, in a state where the protective panel 1 is closed, it is possible to prevent the power source from being applied even when the protective panel 1 is warped by an external force and accidental key input due to the depression of a key is performed, which prevents power from being consumed wastefully.

However, when a strong external force is applied to the protection panel in a non-use state in which the power switch is turned off and the protection panel is closed,
Due to the bending of the protective panel, the keyboard is pressed and key input occurs, causing the device to turn on and wasteful battery consumption. In order to prevent such an unexpected key input, it is conceivable to increase the strength of the protection panel, but problems such as an increase in the overall thickness of the device and an increase in weight occur as the thickness of the protection panel increases. . The present invention has been made in view of the above problems, and when the protection panel is closed,
An object of the present invention is to provide a power supply control device for information equipment, which can be controlled to maintain a power-off state regardless of the presence or absence of key input.

FIG. 3 is a flowchart showing the procedure of power control of the information equipment according to the embodiment. In the power control of the information equipment in the present embodiment, by turning off the power switch, the power supply is turned off except for the constantly operating unit that operates with a small amount of power, and the power is turned off. It is configured so that the power can be turned on and the operation can be started by an operation. Further, the information equipment according to the present embodiment is provided with a keyboard on the surface of the equipment and is provided with a protective panel for covering the keyboard when not in use, as in the case shown in FIG. 4 in the prior art. The opening / closing hinge portion of the protective panel of the device in this embodiment is configured as shown in FIG. In FIG. 2, a hinge portion 2 of a protection panel 1 is formed at a rear end portion of a main body 4, and the protection panel 1 is openably and closably attached with the hinge portion 2 as a rotation axis. A protective panel open / close detection switch 3 is provided near the hinge portion 2 of the main body 4, and the protective panel open / close detection switch 3 is configured to be turned off when the protective panel 1 is closed. The protection panel open / close detection switch 3 is connected to a system control device 6 for controlling the entire equipment system as shown in FIG. The equipment system includes a central processing unit 7 for performing information processing, a power supply control device 5 for controlling on / off of a power supply, an output device 8 such as a display, a key input device 9 for a keyboard, and the above system control. And a device 6. Along with this equipment system, the protection panel open / close detection switch 3
The power supply control of the embodiment information equipment provided with is executed according to the procedure of the flowchart shown in FIG. In FIG. 3, when the power switch provided in the information device is operated to be turned off (step 1), the system control device 6 turns off the power supply to the central processing unit 7 and the output device 8 by the power supply control device 5. Since the command is output, the power control device 8
Performs the control corresponding to the command to put the device in the power saving state (step 2). Next, the system control device 6 checks whether or not there is a key input from the key input device 9 (step 3), and when there is a key input, checks the state of the protection panel open / close detection switch 3 (step 4). When the protection panel open / close detection switch 3 is off, that is, when the protection panel 1 is closed, the power saving state is maintained. When the protection panel opening / closing detection switch 3 is on, that is, when the protection panel 1 is open, the system control device 6 turns on the power supply to the central processing unit 7 and the output device 8 whose power supply is controlled to be off. The command is output to the power supply controller 5 (step 5), and the power supply controller 5 turns on the equipment. The system control device 6 transfers the operation control of the device to the central processing unit 7, so that the device is in the use state (step 6). When the protection panel 1 is closed by the power control by the protection panel open / close detection switch 3 as described above, when the keyboard 2 is pressed by the bending of the protection panel 1 due to a strong external force. In addition, the power is not controlled to be turned on, which avoids wasteful power consumption. In the present embodiment, the input means controlled to turn on the power is an arbitrary key input of the keyboard, but it may be controlled by other input such as input from the communication device.
