Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer device that processes information manually input from human power means, and particularly to a computer device having a flat display device.

[Conventional technology]

Due to recent advances in electronic technology, computer equipment has become smaller and lighter, and from desktop type to portable laptop type, it is rapidly becoming lighter and lighter. Instead of display devices, the development of flat-type display devices, such as plasma displays, liquid crystal displays, and backlight type liquid crystal displays, is largely due to the commercialization of various displays.

Such a display device is usually configured so that its position and angle can be changed between when it is stored in a computer device and when it is used, so that it can be adjusted to suit the viewing angle of the user. There is.

[Problem to be solved by the invention]

In addition, when performing power setting to move the flat display device using electric power, when the power is turned off regardless of the operating position of the flat display device,
Since the position is fixed midway, there is a high risk that the device will come into contact with other items when being carried, forcing the user to be extremely careful when handling it, which greatly reduces operational efficiency. Deteriorate. Therefore, when transporting the flat display device, it is necessary for the user to return it from the operating position to the storage position, such as manually returning it to the storage position or turning on the power and returning it to the storage position. However, there was a problem in that it increased the burden on the user.

The present invention was made in order to solve the above-mentioned problems. In a computer device having a mechanism for driving a flat display device, the present invention monitors the power on/off state and arranges the flat display device. It is an object of the present invention to provide a computer device that can automatically return its position to a predetermined storage position.

(Means for Solving the i1m! Problem) A computer device according to the present invention includes a drive means for moving the flat display section and placing it in a predetermined position, and a drive means for controlling the drive means based on a human power that instructs to turn on and off the power. A return control means is provided for returning the flat display section to a predetermined storage position.

[Effect]

In this invention, when a power on/off instruction is given manually,
The return control means controls the drive means to return the flat display section to a predetermined storage position, and then turns off the power.

(Embodiment) FIG. 1 is a block diagram illustrating the configuration of a computer device showing an embodiment of the present invention. Reference numeral 1 denotes a CPU, and a control program (flowchart shown in FIG. 3) stored in an internal memory (not shown) is shown in FIG. (including the interrupt processing procedure shown in FIG. 1).

2 is a flat display section (flat display), and the CPU
The processing results and data entered manually from the keyboard 3 are displayed.

Reference numeral 4 denotes a drive circuit, which is composed of a driver (not shown) and a stepping motor, and drives the stepping motor so as to move the flat display section 2 from the home position to a predetermined operating position. Note that the stepping motor is provided with a plurality of reduction gears so that appropriate rotational force is transmitted to a gear fixed to a rotating shaft that rotates the flat display section 2.

5 is a power supply control circuit, which includes a power supply 6 and a power switch 7.
It supplies power to each part while the power switch 7 is on, and when the power switch 7 is turned off, it does not immediately stop supplying the power 6 but generates an interrupt command IRQ to the CPUI.

Note that the CPU also serves as a return control means of the present invention, and when the power switch 7 is switched from on to off, an interrupt command IRQ, which is an instruction to turn on and off the power, is output to the interrupt input of the CPU 1, and serves as a driving means. The stepping motor is controlled to return the flat display section 2 to a predetermined storage position (home position), and then the power supply control circuit 5 turns off the power supply 6.

FIGS. 2(a) and 2(b) show the flat display section 2 shown in FIG.
FIG. 2 is a diagram illustrating the moving state of the vehicle, in which the same parts as in FIG. 1 are denoted by the same reference numerals.

In the figure, 8 is the main body of the device.

Note that FIG. 2(a) corresponds to the state before the start of operation after the power is turned on, and FIG. 2(b) corresponds to the state before the power switch 7 is pressed (ON state) or immediately after the power switch 7 is turned OFF. .

FIG. 3 is a flowchart illustrating an example of an interrupt processing procedure according to the present invention. Note that (1) and (2) indicate each step.

When the power switch 7 is turned on, for example, as shown in FIG. 2(a), the flat display section 2 opens outward with the upper part of the device main body 8 as an axis, and stops at a predetermined angle. In this state, when the operator turns off the power switch 7, c
This flow starts when an interrupt command IRQ is input to pui.

The CPU 1 outputs a command to the drive circuit 4 to pull in the flat display section 2 and return it to the home position (the position where the flat display section 2 is on the side surface of the device main body 8 as shown in FIG. 2(b)). After the process is completed, the power supply from the power source 6 is cut off 2), and the process is ended.

In addition, in the above embodiment, a computer device in which the flat display section 2 can be placed at a predetermined position when the power source 6 is turned on is explained as an example, but the flat display section 2 is returned to the home position only when the power source 6 is turned off. An automatic return process may be executed.

〔Effect of the invention〕

As explained above, the present invention includes a driving means for moving the flat display section and placing it in a predetermined position, and a driving means for controlling the driving means based on a human power instruction to turn on and off the power to move the flat display section to a predetermined storage position. Since the return control means is provided, the flat display section returns to the predetermined storage position depending on whether the power of the computer device is turned on or off, so that the burden on the operator in storing the computer device can be reduced. Therefore, even if the power is cut off, the flat display unit will not be placed in the position it was in use, but will return to the specified storage position, which provides advantages such as preventing damage when carrying the device. It has a great effect.
