Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device having excellent portability (generally, a paper size B5 and a mass of about 800 g or less), which is provided with liquid crystal display devices at two locations within the same main body.

[0002]

2. Description of the Related Art In a conventional portable information processing device, it is a general use method to carry the portable information processing device while the liquid crystal portion is closed. Therefore, all the simple confirmation items, such as confirmation of the schedule and confirmation of the number of incoming e-mails, from the information processing work involving complicated calculations are performed after the liquid crystal unit of the information processing device is opened and the system of the device is started up. .

[0003]

According to the above-mentioned prior art, it is necessary to start up the system of the device even for the above-mentioned simple confirmation items while carrying the device, for which a troublesome operation of opening the liquid crystal display unit is required. Will be needed. Further, displaying these simple confirmation items on the liquid crystal causes a problem that power consumption is advanced and battery life is shortened.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems and provide a portable information processing device with improved usability.

[0005]

In order to solve the above-mentioned problems in the prior art, a sub liquid crystal and a display switch are provided on the back side of the main liquid crystal. A predetermined function can be displayed on the sub liquid crystal. Specifically, an internal switch unit is provided which is interlocked with the opening and closing of the liquid crystal unit, and the sub liquid crystal has a sub liquid crystal display switch which operates according to the open / closed state of the liquid crystal unit and is arranged in the vicinity of the sub liquid crystal. Further, the sub liquid crystal display control unit is provided with an O sub liquid crystal display unit.
By performing N, the information of the information processing control unit is displayed. The information processing control unit is connected to the main liquid crystal display control unit, the information input unit, the information output unit, and the battery control unit.

That is, in the portable information processing apparatus of this type, the liquid crystal portion is normally closed when being carried, which causes a problem due to the prior art. However, according to the above-mentioned means, even if the liquid crystal part is closed, the sub-liquid crystal display switch becomes effective by turning on the internal switch linked to the opening and closing of the liquid crystal part, and the information of the predetermined information processing control part (mere confirmation items Etc.) can be displayed on the sub liquid crystal.

When the liquid crystal portion is opened, the internal switch is turned off, so that the display is forcibly interrupted if the sub liquid crystal is being displayed. Therefore, even if the user accidentally touches the sub liquid crystal display switch during information processing work, it is not necessary to display the sub liquid crystal in a position that is difficult to confirm during normal use.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS.

The portable information processing device 1 comprises a liquid crystal part 2 and an input part 3, and in the input part 3, the LCD case 4,
Tablet 5, main liquid crystal 6, holding material 7 on the back side thereof,
The sub liquid crystal 8 and the LCD case 9 are provided in this order. The input unit 3 is provided with a keyboard 10, and the liquid crystal unit 2 and the input unit 3 are rotatably connected by a hinge 11 at the rear of the device. Further, a sub liquid crystal display button 12 is provided near the sub liquid crystal 8 display portion of the LCD case 9. Further, the input section 3 has a structure in which an operation pen 13 for instructing the content to be displayed on the liquid crystal section 2 via the tablet 5 is housed on the front side.

The internal system configuration includes an information processing control unit 21, an input unit 22, an output unit 23, and a main liquid crystal control unit 2.
4, the battery control unit 25 and the sub liquid crystal display switch 26 are connected to each other. A main switch control unit 27 and a liquid crystal unit opening / closing switch unit 28 are connected to the battery control unit 25. Further, the liquid crystal unit opening / closing switch unit 28, the sub liquid crystal display switch unit 26, and the sub liquid crystal display control unit 2
9 is connected to form the entire system of the portable information processing device 1.

Next, the usability of the present invention will be described in detail.

FIG. 5 shows the information displayed on the sub liquid crystal 8 before the liquid crystal unit 2 is opened or closed, that is, when the user takes out the portable information processing device 1 while carrying it. The user presses the sub liquid crystal display button 12 as shown in FIG. As internal information processing at this time, since the liquid crystal unit 2 of the portable information processing device 1 is closed, the liquid crystal unit opening / closing switch unit 28 is turned on, the sub liquid crystal display switch unit 26 becomes effective, and the user operates it. Information is displayed on the sub liquid crystal 8. At this time, the information displayed on the sub liquid crystal 8 side is predetermined information.

In FIG. 5, the user has performed a series of operations to see the number of incoming e-mails, but if he wants to see different information as shown in FIG. 7, he can change the time when the sub liquid crystal display button 12 is pressed. The battery charge amount of the portable information processing device 1 can be confirmed without opening the system by opening the liquid crystal part 2 and turning on the main switch of the device.

Needless to say, the entire system and flow chart shown in FIGS. 4 and 6 are examples of the embodiment, and the display means on the sub liquid crystal 8 according to other system configurations and flow charts are not limited.

Further, as shown in FIGS. 8 and 9, even if the shapes of the LCD cases 33 and 34 are changed, the sub-liquid crystal can be provided, so that it is possible to provide a portable information processing device having excellent design according to each application. Becomes

As described above, according to the present invention, if the means for displaying the predetermined information on the sub-liquid crystal 8 provided on the back side of the main liquid crystal 6 is provided, the user does not have to bother opening and closing the liquid crystal unit 2. Without, you can easily check the information.

Further, if the amount of charge of the battery is easily known in advance, there is an effect that it is possible for the user to determine whether or not the battery needs to be charged before carrying it by considering the usage time.

Further, even when the liquid crystal unit 2 is opened or closed even while the sub liquid crystal 8 is being displayed, the liquid crystal unit open / close switch unit 2
In the state shown in FIG. 7, even if the user mistakenly presses the sub liquid crystal display button 12, the sub liquid crystal 8 is not displayed and power consumption can be prevented from being reduced by unnecessary display.

[0019]

As described above, according to the present invention, by displaying predetermined information on the sub liquid crystal, the user can improve the usability without the trouble of opening and closing the liquid crystal portion. Further, since the information can be viewed without starting up the entire system of the portable information processing device, there is an effect that the power consumption of the battery is small and the life of the battery can be extended.
