Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus provided for, for example, a computer and its application equipment such as a terminal device, a word processor, and an electronic notebook.

[0002]

2. Description of the Related Art Conventionally, an information processing apparatus with a display panel such as a personal computer and a word processor has generally been provided with a main body including a power supply unit and a circuit board, a keyboard as an input section, and a display unit including a display panel. By inputting document data such as characters and figures by operating the keyboard,
A document is created by displaying this document data on the display panel.

An example of the above information processing apparatus is shown in FIG.
There is a laptop type as shown in. In this laptop type device, a display unit 32 having a display panel 33 is configured to be an opening / closing type that also serves as a cover of a keyboard 34, and the display unit 3 is used when the device is used.
The device 2 is used in a vertical direction with respect to the device main body 31 or is tilted slightly rearward from the vertical direction.

Some information processing apparatuses allow handwriting of document data from a display panel. Such an apparatus has a display input unit 4 as shown in FIG.
The display panel displaying the document data by manually inputting the document data with a stylus pen or the like to the liquid crystal display panel 42 having the touch input function provided in the display input unit 41. 42
The document data can be input from above.

Incidentally, such a device is provided with a display angle adjusting function, and the operability of handwriting input is improved by adjusting the display panel 42 to a horizontal position or a position tilted slightly forward from the horizontal. ing.

Further, it has been proposed that the laptop type device of the key input type as shown in FIG. 9 has a liquid crystal display panel having a touch input function, thereby having a handwriting input function. As such a device, a display panel 51 as shown in FIGS. 11A and 11B can be horizontally tilted at a rear position, and a display panel 61 as shown in FIGS. Some of them can be placed horizontally, and such movement of the display panel improves operability in handwriting input.

[0007]

However, the above-mentioned conventional information processing apparatus having both the key input function and the handwriting input function has the following problems.

First, in a device of the type shown in FIGS. 11 (a) and 11 (b), when handwriting input, the horizontally tilted display panel 51 is arranged at the back of the device, so that the operability is slightly poor. Also, there is a possibility that the keyboard on the front side may be erroneously pressed when inputting on the display panel 51.

Next, in a device of the type shown in FIGS. 12 (a) and 12 (b), the display panel 61 uses the keyboard 6 when inputting by handwriting.
Since it is placed right above 2, it is not possible to perform key input from the keyboard 62, and it is impossible to use both key input and handwriting input in consideration of operability.

In the handwriting input operation on the display panel having the touch input function, the handwriting on the display panel at an angle nearly vertical is easily performed because the display panel is substantially at the eye level of the user. Only in case. Further, when a laptop type device as shown in FIG. 9 is used, it is generally operated at a position below the eye level of the user (approximately chest height). Therefore, when the display panel capable of handwriting input is applied to the device of FIG. 9 as it is, the operability of handwriting input becomes very poor.

[0011]

In order to solve the above-mentioned problems, an information processing apparatus according to a first aspect of the present invention has a character,
The display input means includes a keyboard input means for key-inputting document data such as figures and the like, and a display input means for displaying the document data on the display screen and enabling handwriting input of the document data from the display screen. The following means are taken in the information processing device mounted in the direction of opening and closing the keyboard input means.

That is, both ends are rotatably attached to the keyboard input means and the display input means, respectively, so that the display input means can open and close the keyboard input means and the display input means can be inverted. An arm,
A slide mechanism for sliding the display input means is provided to adjust the front-back position of the display screen.

In order to solve the above-mentioned problems, an information processing apparatus according to a second aspect displays a keyboard input means for key-inputting document data such as characters and figures, and displays the document data on a display screen. In the information processing apparatus provided with a display input unit capable of handwriting document data from the display screen, and the display input unit is attached in the direction of opening and closing the keyboard input unit, the following means are taken. .

That is, in the display input means, an input portion for inputting handwriting and a display portion rotatably attached to the keyboard input means for displaying document data are vertically divided into two stages. , A movable support arm having one end attached to a coaxial keyboard input means having a display unit pivotally attached, and the other end pivotably attached to the input unit, the input unit and the display unit being integrated. In order to enable the opening / closing operation of the keyboard input means by the display input means and the inversion operation of only the input section, a lock mechanism for locking and unlocking the movable support arm between the input section and the display section is provided.

[0015]

According to the structure of the first aspect, the display input means is rotationally moved from the unused state of the device whose display screen is closed around the rotation axis of the keyboard input means and the movable support arm. Then, the set state can be obtained by normal key input with the display screen opened. Then, from this set state, the display input means is rotated (reversed) by 180 ° about the rotation axis of the display input means and the movable support arm, and then the rotation axis of the keyboard input means and the movable support arm is moved. When the display input means is rotationally moved in the closing direction around the center, a set state in which the display screen of the display input means is arranged in front of the keyboard input means is obtained. Further, when the display input means is slid rearward from the set state by the slide mechanism, the set state is obtained in which the display input means is arranged directly above the keyboard input means with the display screen opened.

According to the second aspect of the invention, the lock mechanism is used to lock the input section and the display section of the display input means to the movable support arm, and the display screen is closed. When the display input means, which is a combination of the input part and the display part, is rotationally moved around the rotary shafts of the movable support arm and the display part with respect to the keyboard input means, the set state is obtained by normal key input with the display screen opened. Is obtained. Then, from this set state, the respective locked states of the input section and the display section are released, the input section is rotated (reversed) 180 ° about the rotation axis of the input section and the movable support arm, and then keyboard input is performed. When the input section is rotationally moved in the closing direction around the rotation axis of the means and the movable support arm, a set state in which the display screen of the input section is arranged in front of the keyboard input means is obtained.
