Abstract

(57) [Abstract] [Purpose] In the past, the portable computer, the word processor, and the electronic notebook had a small screen of the display device and were difficult to see because they were portable. Therefore, the area of the display screen was increased without losing the portability to improve the visibility and workability of the display. [Structure] Separately from a conventional open-close type display device (main display device) such as a portable computer, a sub-display device is attached to the main display device so as to be openable and closable, and the sub-display device is provided above or to the side of the main display device. I made it so that I could expand it and see both screens together. Also, portability was secured by folding the sub-display together with the main display.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a portable computer, a word processor, and an electronic notebook (hereinafter, referred to as a portable computer, etc.) in which a plurality of display devices are installed to increase the area of a display screen and improve visibility and workability.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 11, in a portable computer or the like, a display device F having a display screen G is installed by attaching one end to a main body E so that the hinge EE can be opened and closed.

[0003]

[Problems to be solved by the device]

 The screen G of the conventional display device F is composed of, for example, a set of 640 dots in the horizontal direction × 400 dots in the vertical direction, and the characters and figures are displayed by controlling the brightness of the points. There is a limit to the number of characters that can be displayed on the screen due to the above, and so-called full-width characters such as Japanese can display up to 40 characters on the left and right and up to 25 lines on the top and bottom. There was a problem such as inconvenience when trying to edit or refer to before or after a long sentence. For this reason, the size of displayed characters may be reduced to increase the number of displayed characters, but it is not practical because it becomes difficult to see. Also, when using so-called spreadsheet software, creating a long table horizontally or vertically has poor visibility due to the restriction of the display range due to the space of the display screen, and there is a problem that editing is inconvenient. .. Alternatively, when a plurality of software programs are started simultaneously and one screen is divided and displayed, there is a problem that it is very difficult to see because the display range is narrow. For this reason, it has been attempted to increase the screen area of the display device to increase the number of dots, for example, 640 horizontal dots x 480 vertical dots, or increase the number of vertical and horizontal dots to increase the number of display characters and display range. There is a restriction that the area of the display screen is increased due to the demand for compactness, or there is a drawback that the display character size becomes smaller if the number of dots is increased without increasing the area of the display screen. Therefore, it was not possible to solve the problem all at once because of the conflicting visibility.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in a portable computer or the like, in addition to the conventional openable display device (main display device) attached to the main body, an openable display device (sub display device) can be opened and closed on the main display device. By installing it, the screen of the sub-display device can be expanded near or above the screen of the main display device, expanding the area of the display screen and making it possible to see both screens together. In addition, portability was ensured by folding the sub-display together with the main display.

[0005]

[Action]

 According to the present invention, by opening and closing the sub display device above the main display device and displaying it together with the main display device in a vertically long integrated screen, long texts can be edited and long and vertically long screens can be displayed. When creating, the visibility on the screen will be improved, and if the sub display device is opened or closed to the left or right of the main display device so that the main display device and the main display device are displayed as a long integrated screen on the left and right, one line The visibility on the screen is improved when editing a sentence with a large number of characters, or when creating a table with long left and right sides, and it is possible to solve the various problems that existed in the past. If multiple software programs are activated and displayed, or if other parts of the text are displayed together, if they are displayed on the screens of the main, sub, and separate display devices, one screen will be displayed. The visibility is improved as compared with the conventional case where the display is divided, and the above-mentioned problems are eliminated.

FIG. 5 shows a state in which the main display device 11 is opened via the hinge CC of another portable computer C of the present invention. A hinge 13 provided above the main display device 11 is provided with an L-shaped member 15 which is pivotable in the vertical direction, and a hinge 14 provided on the side of the L-shaped member 15 is attached with a sub-display device 12 which is pivotable laterally. There is. FIG. 6 shows a state in which the sub display device 12 of FIG. 5 is opened upward together with the L-shaped member 15 via the hinge 13, and the main and sub display devices are vertically arranged to display the display screens 16 and 17 in a large size vertically. You can do it. FIG. 7 shows a state in which the sub display device 12 of FIG. 5 is opened laterally via the hinge 14, and the main and sub display devices are arranged on the left and right sides so that the display screens 16 and 17 can be displayed large on the left and right sides. .. The same operation can be achieved even if the mounting positions of the hinges 13 and 14 of the main display device and the sub-display device are changed as shown in the next embodiment. Further, the L-shaped member 15 can be made into a mouth shape as in the following embodiment to increase the strength.

An embodiment of the present invention is constructed with reference to FIGS. 8, 9 and 10. FIG. 8 shows a state in which the main display device 18 is opened via the hinge DD of another portable computer D of the present invention. A hinge 20 provided on the side of the main display device 18 provides a mouthpiece member 22 so as to be able to turn sideways, and a hinge 21 provided above the mouthpiece member 22 allows the auxiliary display device 19 to turn vertically. It is installed. FIG. 9 shows a state in which the sub display device 19 of FIG. 8 is opened upward via the hinge 21. The main and sub display devices are vertically arranged so that the display screens 23 and 24 can be displayed large vertically. it can.

[Effects of the Invention] According to the present invention, in a portable computer or the like, the area of the display screen can be expanded while ensuring portability, and the visibility and the efficiency of work such as a computer can be significantly improved. By setting the sub display device above the main display device, it can be displayed as a long vertical screen together with the main display device, improving work efficiency when editing long sentences or creating long vertical tables. You can do it. Also, by setting the sub display device to the left or right of the main display device, it becomes possible to display it as a long integrated screen on the left and right together with the main display device, and edit sentences with many characters in one line and It is possible to improve work efficiency when creating a very long table. Furthermore, if multiple software programs were started or other texts were referenced, and if they were displayed on the screens of the main, sub, and separate display devices, one screen would be displayed separately. The visibility is significantly improved compared to the past. It also has a wide range of applications, such as editing on one screen and displaying the layout on the other screen, or plotting on one screen and displaying graphs and graphics on the other screen.
