Abstract

PURPOSE: To eliminate the misoperation of a key and reduce the fatigue of an operator by forming a palm rest space in front of an input key group. CONSTITUTION: The palm rest space 5 is formed in front of the input key group 4 arranged on the keyboard 3 so that the palms can be placed at the time of key operation. The keyboard itself has the palm rest space 5, so operation can be done more comfortably as compared with a case wherein the palms are put on a desk top without feeling the step between the keyboard 3 and desk top and even when there is not a space margin on the desk top and the palm rest space 5 projects from the top of the desk, the hands operating the keys can be placed on the palm rest space 5, so stable operation is done. Namely, the palm rest space for key operation is secured, so the hands operating the keys become stable, keys are prevented from being misoperated, and the fatigue of the operator is reducible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard which is an input means of an electronic calculator or the like, or an electronic device equipped with a keyboard portion, which is designed to reduce erroneous operation of keys and fatigue of a keyboard operator. Related to the improvement of.

[0002]

2. Description of the Related Art As an input device for electronic equipment such as an electronic calculator, a keyboard 2 provided with a large number of input keys 1 in a predetermined arrangement is widely used as shown in FIG.

[0003]

The shape of the conventional keyboard is almost the same as the shape in which the input keys 1 are arranged, and there is no space for placing the keys when operating the keys on the desk itself. If there is not enough room, the usage will be as shown in FIG. 9, and there will be no space to fix the hand on the desk surface. For this reason, the working hand becomes unstable, the key is erroneously operated, or the operator's fatigue cannot be avoided. This situation was the same in the small electronic device 16 such as the notebook personal computer shown in FIG.

In view of the above situation, the present invention aims to eliminate erroneous key operation and reduce operator fatigue.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a keyboard having a manual placement space formed on the front side of an input key group, a keyboard provided with a pull-down manual placement board at the lower portion of the keyboard, and a keyboard portion. In an electronic device having a keyboard part provided with a hand-placing board that can be pulled out to the front in the lower part, and an electronic device having a cover for covering the keyboard part,
The present invention relates to an electronic device having a keyboard section configured to divide a cover into a display section and an auxiliary cover section, allow the auxiliary cover section to rotate forward, and form a manual placement space in a rotated state. .

[0006]

[Operation] Since a space for placing the key when operating the key is secured, the working hand is stable and erroneous operation of the key is prevented,
Moreover, the fatigue of the operator is reduced.

[0007]

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

FIG. 1 shows a first embodiment of the present invention. In front of the input key group 4 arranged on the keyboard 3,
The hand placing space 5 is formed so that the palm can be placed when the keys are operated.

Since the keyboard 3 itself has the hand placing space 5, as shown in FIG. 2, compared to the case where the palm is placed on the desk top surface 15, the step between the keyboard 3 and the desk top surface 15 is not felt. The work can be performed comfortably, and even when the hand placing space 5 is out of the desk because there is no space on the desk as shown in FIG. 3, the working hand can be placed in the hand placing space 5, so that stable work can be performed.

In FIG. 4, a manual placement board 7 forming a manual placement space 5 is provided slidably below the keyboard body 6 and can be stored when not needed. When the hand placement board 7 is retractable, the hand placement board 7 is used when not in use.
Since the keyboard can be stored in the lower front part of the keyboard body 6, the handleability and storage of the keyboard 3 are improved.

FIG. 5 shows a case in which the present invention is applied to a notebook type or laptop type personal computer 8 or the like. As shown in FIG. 4, the manual placement board 7 is slidable and the keyboard portion 9 is used. It can be stored underneath. In the figure, 10 is a cover having a display screen 11.

[0012] Thus, by pulling out the manual placement board 7 at the time of use, a manual placement space can be easily secured.

FIGS. 6 and 7 show another embodiment. In the other embodiment, the cover 10 is divided into a display portion 12 including a display screen 11 and an auxiliary cover portion 13 serving as a manual placement space 5. The display unit 12 rotates in the opposite direction,
Further, the auxiliary cover portion 13 is adapted to rotate toward the front side, and the auxiliary cover portion 13 is rotatably connected to the keyboard portion 9 side by a link 14 so as to assist when the auxiliary cover portion 13 is rotated toward the front side. The manual placement space 5 which is the upper surface of the cover 13 is flush with the keyboard 9 (see FIG. 7).

[0014]

As described above, according to the present invention, a space for placing a hand at the time of operating a key is secured, so that the working hand is stable, erroneous operation of the key is prevented, and fatigue of the operator is reduced. To be done.
