Abstract

PURPOSE:To easily execute operation even when it is necessary to execute an input only with one hand by generating information, which are generated by pushing a key to be arranged in a right half part or a left half part on a keyboard, with a key to be arranged in the left half part or right half part in an opposite side. CONSTITUTION:When any one key of a right character key group 5 is pushed while a light shift key 3 is pushed, the information, which are generated when the key in the symmetrical position of a left character key group 4 is pushed, are inputted. Namely, for the pushed key and inputted information, the respective keys to be mutually in the linear symmetrical position to a dividing line CL, which is vertically drawn between the right character group 5 and left character group 4, are correspondent. For example, when a key 5a is pushed while the left shift key 3, the information are converted to the information which are generated when a key 4a to be the symmetrical position in the left character key group 4 is pushed to the key 5a. Thus, even when it is necessary to execute the input only by one hand, the operation can be easily executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard input device used as an information input means in an information processing device.

[Conventional technology]

Conventional keyboard input devices used as a means of inputting information in information processing devices are mainly those with a key arrangement similar to the one in which character keys 11 are arranged in four rows as shown in FIG. For the purpose of simplifying and speeding up the operation, character keys 21A and 21 as shown in FIG.
A special key arrangement in which the keys B are arranged symmetrically on the left and right and allows input using both hands equally has also been put into practical use.

[Problem to be solved by the invention]

Among conventional keyboard input devices with the above-mentioned key layouts, keyboard input devices with a symmetrical character key layout as shown in Figure 3 in particular have character keys arranged so that efficient input operations can be performed using both hands. Because the keys are arranged in such a way that when you try to type with only one hand, the keys closer to your hand are easier to press, but the keys farther away on the opposite hand are harder to press. There is.

An object of the present invention is to solve the drawbacks of the conventional keyboard input device having a symmetrical character key arrangement as described above. An object of the present invention is to provide a keyboard input device that is easy to operate without losing μs.

[Means to solve the problem]

The keyboard input device of the present invention is a keyboard input device comprising a left character key group and a right character key group arranged symmetrically, each of the left character key group and the right character key group having a right shift key and a left shift key. However, when the right shift key or the left shift key is pressed and any key in the left character key group or right character key group is pressed, the right character located at a symmetrical position to the pressed key is displayed.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing one embodiment of the present invention.

It has a numeric key group 6 arranged to the right of a right character key group 5. The left character key group 4 and the right character key group 5 are separated by the dividing line C.
They are arranged symmetrically with L as the axis of symmetry.

A right shift key 2 and a left shift key 3 are provided at the bottom of the inside of the left character key group 4 and right character key group 5, respectively. By pressing these keys, a signal indicating that the key information should not be converted is sent. Sent out.

Inputting information using the keyboard input device configured in this way is performed by scanning the input command from the central processing unit of the information processing device and converting information regarding the pressed keys into JIS code or the like using software. . Right shift key 2 or left shift key 3
When is pressed, a key information exchange routine is added in the conversion software based on the information from these keys, allowing the following inputs. That is, when any key in the right character key group is pressed while holding down the left shift key 3, the information when the key at the symmetrical position in the left character key group 4 is pressed is input. In other words, the keys to be pressed and the information to be input correspond to the keys located in line-symmetrical positions with respect to the dividing line CL drawn virtually between the right character key group 5 and the left character key group 8. For example, if the key 5a is pressed while holding down the left shift key 3, the information is converted to information generated when the key 4a located in the symmetrical position in the right character key group 4 is pressed with respect to the key 5a.

〔Effect of the invention〕

As explained above, the keyboard input device of the present invention includes:
Information generated by pressing a key placed on the right or left half of the keyboard can also be generated by pressing a key placed on the opposite left or right half, so information can be generated on the keyboard with only one hand. This has the effect that the same operations as operating the keys on both the left and right sides of the computer can be performed easily. Therefore, it is possible to easily perform operations such as turning the pages of a document with one hand, or pressing the key with the other hand while following the letters written on the document with one's fingers.

Claims (1)

[Claims] In a keyboard input device including a left character key group and a right character key group arranged symmetrically, each of the left character key group and the right character key group has a right shift key and a left shift key, and the right shift key or the left When you press the shift key and press any key in the left character key group or right character key group, when you press a key in the right character key group or left character key group that is in a symmetrical position to the pressed key. A keyboard input device characterized by outputting information converted into generated information.
