Abstract

(57) [Summary] [Purpose] The power is turned on / off in response to the opening / closing operation of the display unit to reduce the number of operations of the power switch and prevent forgetting to operate the power switch. [Configuration] By storing a condition in a register that enables power on / off in response to opening / closing of a display unit by an opening / closing mechanism unit, a power control unit turns on power based on a detection result of a detection switch. Alternatively, it is possible to control the shutoff so that the power supply operation can be performed in one step and the power switch operation can be prevented from being forgotten.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic device having a display unit including a flat display, and more particularly to an electronic device that turns on / off a power source according to opening / closing operation of the display unit.

[0002]

[Prior Art]

 In recent years, electronic devices such as laptop computers and Japanese word processors equipped with a flat display called a clamshell type or a lunch box type have become popular. Since such electronic devices use flat displays consisting of plasma displays and liquid crystal displays, they can be made smaller and lighter and are easier to carry and handle.

FIG. 2 shows a laptop computer as an example of such an electronic device, which includes a main body 2 including a keyboard 1 and an arithmetic processing unit (not shown), and a low power consumption type display device such as a liquid crystal display. The display unit 3 is supported by the main body unit 2 via an opening / closing mechanism unit 4 such as a hinge mechanism so as to be freely openable / closable in the vertical direction in the arrow direction.

By the way, in an electronic device in which the display unit 3 as described above is openably and closably supported via the opening / closing mechanism unit 4, the procedure for turning on the power of the electronic device is as follows: Raise part 3 to open. (2) Turn on the power switch and turn on the power. Is generally required, and the opening / closing operation of the display unit 3 is an indispensable operation procedure for using electronic devices.

[0005]

[Problems to be solved by the device]

 However, in order to use the above electronic equipment, it is necessary to operate the display unit 3 in two steps: opening and closing the display 3 and turning the power switch on and off, and turn off the power switch when the electronic equipment is not in use. If you forget to perform this operation, the battery, which is the driving power source, will be wasted and the battery life will be shortened.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electronic device that turns on / off a power source in response to opening / closing operation of a display unit.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an opening / closing mechanism part for supporting the display part to the main body part so as to be openable and closable in an electronic device having a main body part and a display part, and the opening / closing mechanism part. The detection unit that detects the opening and closing of the display unit by the, the storage unit that stores the input / shutdown condition of the power input in advance, the condition stored in this storage unit and the detection result by the detection unit. It is characterized by comprising a power supply control unit for controlling power on / off based on the power supply.

[0008]

[Action]

 Since the present invention is configured as described above, the detection result of the detection unit is stored in the storage unit by storing the condition that enables the power to be turned on or off in response to the opening or closing of the display unit by the opening / closing mechanism. The power is turned on or off based on the above, and a one-step operation is sufficient and forgetting to operate the power switch can be prevented.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an electronic device according to an embodiment of the present invention. The same parts as those in FIG. 2 are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 1, reference numeral 10 denotes, for example, a mechanical detection switch provided in an opening / closing mechanism unit 4 that supports the display unit 3 so as to be opened and closed, and detects the open / closed state of the display unit 3. That is, when the display unit 3 is opened, that is, when the display unit 3 is raised from the keyboard 1, the detection switch 10 is turned on, and the display unit 3 is closed, that is, the display unit 3 is closed to the keyboard 1 side. Then, the detection switch 10 is turned off. The output of the detection switch 10 is output to the power supply control unit 11 including a microcomputer.

Further, 12 is a power switch conventionally provided on a side surface portion of an electronic device or the like, which turns on / off the power via a power control circuit 11.

Reference numeral 13 is a method of turning on / off the power input from the keyboard 1 as an input unit, that is, whether or not the power can be turned on / off in response to opening / closing of the display unit 3. The register 13 stores and holds the condition of, for example, "1" when enabling / disabling the power supply corresponding to the opening / closing of the display unit 3, and "0" when not enabling the power supply. Are stored respectively. The conditions stored in the register 13 are output to the power supply control unit 11 similarly to the output of the detection switch 10.

Further, the power supply control unit 11 turns on and off the power supply when the power supply switch 12 is opened and closed, and also controls the power supply so that the power supply is turned on and off based on the outputs of the detection switch 10 and the register 13. Do.

The power supply controller 11 and the register 13 are stored in the main body 2.

Next, the operation of the embodiment of the present invention having the above configuration will be described.

First, when the power switch 12 is opened / closed, the power control unit 11 gives priority to the opening / closing of the power switch 12 and controls the turning on / off of the power.

On the other hand, when the condition for turning on / off the power supply corresponding to the opening / closing of the display unit 3 from the keyboard 1 is input to the register 13 and “1” is stored, the opening / closing of the display unit 3 is performed. Corresponding power supply can be turned on / off, and the power supply control unit 11 controls the power supply on / off based on the on / off output of the detection switch 10 regardless of the opening / closing operation of the power switch 12. However, if the power switch 12 is closed while the power is turned on by opening the display unit 3, the power switch 12 has priority over the open / close operation of the power switch 12. Take control.

If the condition for turning on / off the power supply corresponding to the opening / closing of the display unit 3 from the keyboard 1 is not input to the register 13 and “0” is stored, the power supply control unit 11 determines The power on / off control is performed by opening / closing the power switch 12 without controlling the power on / off corresponding to the opening / closing of the display unit 3.

In the above embodiment, the power supply can be turned on / off corresponding to the opening / closing of the display unit 3, but the present invention is not limited to this, and the power supply can be turned on / off in response to the opening operation or the closing operation of the display unit 3. The power supply may be controlled by either turning on or off.

Further, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
