Description

Character input keyboard {Key board}

The present invention relates to a character input keyboard used in a desktop computer or a personal digital assistant (PDA), and more particularly, a key group of keys arranged on the front and rear surfaces of the keyboard body by wrapping the sides of the keyboard body. By preventing the strain on the wrist muscles to smoothly perform long-term character input work, the character input operation can be performed on the non-table, thereby increasing the space utilization of the table, and even in standing position while carrying The present invention relates to a new type of text input keyboard that enables a user to perform a text input operation smoothly without depending on the structure.

A commonly used desktop computer uses a text input keyboard on the upper surface of the table. The currently known text input keyboard is a horizontal keyboard body in which a plurality of keys are arranged on a plate keyboard body. A plurality of keys are arranged in the structure, or a plurality of keys are arranged on an inclined surface inclined toward the user.

However, the desktop computer keyboard described above was inconvenient to use because it caused a strain on the muscles of the wrist because the user's wrist was twisted inward and the character was input because the keys were arranged in a plane. In the case of long periods of time, muscle fatigue increases, which not only hurts health, but in severe cases, it can not be ruled out to develop occupational diseases.

In addition, due to the large size and volume of the keyboard for inputting characters, the keyboard occupies a large area on the table, and thus has the disadvantage of preventing other work on the table while using the desktop computer. There was a hassle to put on another object such as a monitor or computer body.

On the other hand, in recent years, the PDA (Personal Information Terminal), which has an electronic organizer function and some functions of a personal computer (PC), has been in the spotlight due to the development of the Internet information industry, and is connected to a mobile phone terminal or an external modem. Although the function is improved enough to send or receive fax or e-mail, the character input device is implemented only on the front of the limited-size body of the media, so you can use the software to input one letter by pressing the number key several times. Or, using the software associated with a separate watch screen, or using the software associated with the handwriting input device.

However, the conventional PD has a disadvantage in that it takes a long time to input a long sentence, and in addition, in the case of a touch screen or a handwriting input device, a part of the screen may be used as a character input space to display more information. The space was significantly reduced and there was inconvenience in use.

In addition, by using only one or two fingers or only one pen to enter characters, the character input speed is significantly lower than that of a desktop keyboard using all ten fingers. There are various problems such as an increase in manufacturing cost.

The main object of the present invention is to provide a new type of character input keyboard that can prevent the strain of the wrist muscle to smoothly perform a long time character input operation.

Another object of the present invention is to provide a character input keyboard that can increase the space utilization of the table by enabling the character input operation even on a non-table.

It is still another object of the present invention to provide a character input keyboard capable of smoothly performing a character input operation without depending on other structures even in a standing posture while carrying.

It is still another object of the present invention to provide a character input keyboard which can be applied to a PDA more usefully to perform character input operations more quickly and reduce manufacturing costs without reducing the character input space. .
