Description

A keyboard to support a data input onto personal data terminal}

The present invention relates to the provision of a keyboard having an auxiliary device for key input of a personal digital assistant (aka mobile phone and Internet phone), a hands-free function for convenient communication, and a complex function for charging a terminal.

At present, the personal portable information communication terminal provides a variety of additional services beyond the step of providing only conventional voice communication. Typical functions include text sending / receiving service, stock information sending / receiving, internet access, and chat function. This indicates that personal portable information and communication terminals are becoming the next generation communication means, and the number of users is ahead of 1 PC (Personal Computer) level. In addition, service providers also offer a variety of additional services. Among various service sectors, in particular, functions that cope with existing personal computers (chat), e-commerce, etc. are becoming mainstream, and demand groups utilizing them are increasing exponentially.

However, the current information input device key panel provided by the personal portable communication terminal is very small due to the structural characteristics of the portable and has an inconvenience in use due to the limited configuration of the input key. Chargers for hands-free and personal handheld telecommunications terminals are widely available for cars, but it is difficult to find an all-in-one product suitable for general office and home use.

As described above, in the related art, the key panel provided by the personal portable communication terminal itself is too small and has a lot of inconveniences because it provides implied functions. To solve this problem, methods using a PC have been invented. It has an inconvenient factor that requires the use of intermediate media. In addition, when a personal portable information communication terminal is used for a long time for data communication and voice communication, power consumption of the terminal increases, which is inconvenient.

Accordingly, an object of the present invention is to provide a method in which a user can input data more easily by utilizing a multipurpose keyboard, which is an additional device, in addition to a key panel provided by a personal portable information communication terminal. And, to provide a charging function to increase its utilization. In particular, the keyboard uses its own Micro Processor Unit (MPU), so it can be used independently and includes the functionality of a regular PC keyboard.
