).

In addition, when the information to be communicated with each other is two-way, such as communication between a company and an outside sales representative, the salesperson carries a small personal computer, a so-called mobile gear, as a terminal. There are known technologies that allow mobile gear and company computers to exchange data with each other (for example,
).

In recent years, the performance of mobile phones has improved, the transmission speed has been significantly increased, the liquid crystal display surface for displaying information has also increased in size, and there are also flat-rate mobile phone usage fees. An environment where a large amount of information can be transmitted inexpensively is being prepared. Therefore, if a personal computer as an operation target can be operated using a mobile phone, bidirectional information transmission can be performed by the mobile phone, as is conventionally done with a mobile gear.

However, if an attempt is made to give such a function to a mobile phone, the mobile phone also requires an input / output device similar to a personal computer, but the operation panel provided in the mobile phone has a small area and the number of operation buttons. Therefore, there was a structural problem in making it function as a personal computer terminal as it is.

As an improvement, attempts have been made to expand the keyboard by mechanical means (for example,
On the other hand, there is a problem that the portability of the mobile phone is impaired, or that the structure that is already commonly used of the mobile phone has to be significantly changed. JP 2001-338237 A JP 2002-85916 A JP 2001-338237 A
