Description

Wireless modem for information terminals {Wireless modem for personal Digital Assistant}

The present invention relates to a wireless data modem for an information terminal, and more particularly, by installing a wireless modem inside a terminal case in which a personal digital assistant (PDA) is mounted, thereby enabling wireless data communication. It can transmit / receive various data such as stock quote, sales management automation, transportation and inventory management, convenience facilities and public safety management, and financial insurance, and it is equipped with wireless modem so that the cable connecting information terminal and terminal case is external. The present invention relates to a wireless data modem for an information terminal that is not exposed to the network and is simplified in configuration.

In general, the information terminal is abbreviated as PDA and is referred to as a portable information terminal. The information terminal is a smaller computer, much smaller than a notebook, and has significantly more computer power than an electronic notebook. Since the overall size is small, the size of the display device (LCD) is limited, and it is based on a pen input for writing by using a pen to recognize characters.

Personal information management programs such as schedule management, address book, notepad, etc. are provided as standard, and you can exchange data freely through a connection with a PC. In addition to the built-in programs, you can install and use a new program. Recently, with the development of wireless communication, Internet access through PDA is possible, and PDA is newly pioneering wireless internet field.

Such information terminal improves inefficient method of personal information management through basically provided programs and additional applications, and also provides personal information management program for PC corresponding to personal information management programs of PDA. By connecting PC and PC, it supports modification, addition and backup of inputted information, suggesting a new level of personal information management plan.

PDAs also allow you to connect to your mobile phone on the go regardless of location. The main functions of the Internet, such as web page search, e-mail transmission, PC communication, and stock trading, are available on PDAs.

However, in the related art, the information terminal and the mobile phone have to be connected by a separate cable, which is cumbersome to use. Cell phones serve as a kind of terminal for wireless data communication, but since the cell phones and the information terminals are sold separately from each other, there is a need to connect them with cables. Also, in order to perform wireless data communication with an information terminal, a cell phone is required, so an expensive cell phone must be purchased, and the use of the information terminal is fixed by holding the cell phone in a separate place and holding the information terminal by hand. There was this.

The present invention was developed in view of the conventional problems, and an object of the present invention is to provide a wireless terminal with a built-in wireless modem to enable wireless data communication using a personal digital assistant (PDA). When the terminal is mounted in the terminal case, the information terminal is automatically connected to the wireless modem without a separate cable, so wireless data communication is possible. Also, the cable is not exposed to the outside and the wireless modem and the information terminal are integrated. To provide a data modem.

In order to achieve the above object, the present invention is provided in a wireless data modem for an information terminal for wireless data communication using an information terminal, comprising a terminal case provided with guides on both sides of the front side for supporting the information terminal. The wireless modem is built in for wireless communication, and the lower part of the terminal case is connected to the wireless modem with a cable and is configured to be provided with a terminal connected to the terminal of the information terminal.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a wireless data modem of the present invention, and FIG. 2 is a side cross-sectional view of the wireless data modem of the present invention. The present invention is provided with a terminal case (4) is provided with an information terminal (1) is equipped with an information terminal (1). The information terminal 1 is provided with a display unit 2 for displaying information such as letters, pictures, and numbers on the front side, and a terminal 3 for connecting a communication line on the bottom thereof, respectively. And the side of the information terminal is provided with a control panel such as ON / OFF button, display lamp, battery lamp, earphone jack.

The terminal case 4 has a wireless modem 6 therein. This wireless modem is a modularized communication function of a mobile phone, enabling wireless communication. And the front of the terminal case (4) is formed with a guide piece (5) for holding the information terminal 1 protruding and the terminal (7) connected to the terminal 3 of the information terminal (1) in the lower front of the terminal case Is formed. The terminal 7 and the wireless modem 6 are connected via a cable 8, and when the information terminal 1 is mounted on the terminal case 4, these terminals 3 and 7 are connected to each other and the information terminal ( 1) is connected to the wireless modem 6 via a cable (8).
