Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard, and particularly to a keyboard used in an information processing device, which is equipped with function keys and general keys (character keys) having extended functions.

[Conventional technology]

FIG. 2 is a plan view showing the key arrangement of an example of a conventional keyboard of this type. This keyboard includes general keys (character keys) 2, function keys 3, function expansion keys 4, cursor keys 5, numeric keys 6, and special keys 7 on a main body 1.

-i key (character key) 2, as shown in FIG. 3, is a key for inputting letters, numbers, and symbols, and has two to three functions per key. The function key 3 is a control key that displays certain registered words and has special functions. This also has two or three functions in one key, and these two or three functions included in one key are called extended functions.

The function expansion key 4 is a key for selecting these expansion functions.

There are 5 extended functions.When the extended function key 4 is pressed, the second and third functions are enabled, and when the function key 3 or general key (letter key) is pressed at the same time, the second and third functions are enabled. It has become.

[Problem to be solved by the invention]

In the conventional keyboard mentioned above, in order to use an extended function, you have to press two keys at the same time, so you have to do it with both hands or with one hand in an awkward position. , you can't do it with one hand, and you have to press them at the same time, so if you don't make sure to press the function expansion key, the expansion function will not be selected.

If you do not have a place to put the original and type while holding it in one hand, or if you are forced to type with only one hand, you will not be able to use the extended functions. Another drawback is that even if you can input with one hand, you cannot input reliably.

Therefore, an object of the present invention is to provide a keyboard that allows extended functions to be used even with one hand and allows reliable input.

[Means to solve the problem]

According to the present invention, there is obtained a "keyboard comprising function keys and general keys with extended functions, characterized in that the keyboard is provided with a lock-type function expansion key for selecting the extended function".

〔Example〕

Next, the present invention will be described in more detail with reference to the drawings showing one embodiment of the present invention.

Referring to FIG. 1, the difference between the embodiment of the present invention and the conventional keyboard shown in FIG. 2 is that a lock-type function expansion key 8 is provided. Pressing it a second time locks the key in the down position, and pressing it again unlocks it in the up position.

At this time, the key becomes valid when it is in the down position.

When you want to use an extended function, in addition to the conventional method, you can enter the extended function by first pressing the lock-type function expansion key 8, making sure it is locked, and then pressing the key you want to use the extended function. , by pressing the degree-lock type extended function key 8. This allows you to easily use extended functions with one hand. In addition, since the state of the key can be checked, input can be performed reliably. [Effects of the Invention] As explained above, according to the present invention, by providing a lock-type expansion function key, expansion can be performed with one hand. Function input is possible. You can also check the status of the function extension key.
You can enter extensions accurately.
