Description

Keyboard for smart devices {Keyboard for smart devices}

The present invention relates to a keyboard for a smart device for inputting various information by connecting to a smart device such as a smart phone or a tablet PC. More particularly, the present invention relates to a keyboard for a smart device, The present invention relates to a keyboard for a smart device which can be used by switching numeric keys.

With the advancement of computer and wireless communication technologies, portable smart devices such as mobile phones, smart phones, tablet PCs have been improved in performance and functions become richer. Therefore, even in such smart devices, The same function is performed without difficulty, and a more effective and quick character input means is required.

Generally, in a smart phone, there is a character input function using a numeric keypad. However, there is a disadvantage that it is inconvenient to use a key several times in order to input a character. In addition, a general keyboard type Qwerty keyboard There are a lot of keyboards of smart devices that implement small. In recent years, in a smart device having a touch input device, a keyboard is drawn on a screen, and a touch screen on which a character is input is often used when a picture of the corresponding button is pressed. However, it is true that the character input of these methods is much slower than the keyboard input device used in a typical desktop computer, and is inconvenient for a long time.

In order to solve this inconvenience, there are many keyboards which have a general keyboard shape, which is reduced in size or folded and connected to a portable smart device in case of need, but these keyboard devices use a smart device It can not be used on the lap, and there is a tendency that the function of the smart device is faded.

Prior art related to a keyboard that can be used in connection with a smart device such as the above-mentioned smart phone or tablet PC is disclosed in Korean Patent Publication No. 10-1204151 (character input device of a portable terminal) 10-1511778 (non-interlocked numeric input and character input method and apparatus using numeric keypad for computer), Korean Patent Registration No. 10-1522631 (wireless keyboard apparatus for smart phone), and the like.

However, when the number of keys is reduced, it is troublesome to operate one key several times in order to input a number or various characters. In the case where a numeric key or a letter key is separately configured, There is a problem in that it is inconvenient to store and carry.

Korean Registered Patent No. 10-1204151 (issued Nov. 22, 2012) Korean Registered Patent No. 10-1511778 (Announced on May 13, 2015) Korean Registered Patent No. 10-1522631 (Bulletin of May 26, 2015)
