Description

Adapter for information terminal with Bluetooth chip {Ad apartment for data processor having Bluetooth chip}

The present invention relates to a wireless communication device, and more particularly to an adapter that can be used by applying a short-range wireless communication technology to a mobile phone, PDA or notebook computer.

With the rapid development of information and communication technology, infrared wireless communication IrDA and wireless LAN (IEEE 802) have been used as a means for enabling wireless information communication between electronic devices located in a short distance. Recently, Bluetooth, an innovative technology, has been widely used. Bluetooth is a technology specification that wirelessly connects portable devices such as notebook computers, mobile phones or PDAs at a low cost within a narrow range, and solves the limitations of distance and interference problems of the existing IrDA. Have The concept of Bluetooth could be employed in all digital devices such as printers, fax machines, mice or joysticks.

Bluetooth was launched as an open standard in 1998, when five companies, Ericsson, Nokia, Intel, Toshiba and IBM, formed a consortium called the Bluetooth Special Interest Group (SIG). As of August 2000, 1883 member companies employ it.

Therefore, the newly released digital communication equipment is in the trend of embedded Bluetooth chip itself. That is, the reality is that various digital communication equipments distributed at least before 1998 cannot use the above technology.

The purpose of the present invention for this problem is to provide an adapter for allowing existing digital equipment that does not use Bluetooth technology to use the technology. That is, an object of the present invention is to enable a user to use Bluetooth technology by connecting an adapter including a Bluetooth chip to various digital devices.

The above object has a connection terminal that can be connected to a data input / output terminal provided on the side of an information device such as a computer, a mobile phone, a credit card inquiry machine or a PDA for data communication with an external device, and has a built-in Bluetooth chip. By doing so, it is achieved by an adapter for an information terminal incorporating a Bluetooth chip, which enables the information device to perform wireless data communication with the external device using Bluetooth technology.

Hereinafter, with reference to the accompanying drawings will be described in more detail.

1 is a perspective view of an adapter according to an embodiment of the present invention, showing a format particularly used for wireless mobile phones. 2 is a perspective view showing a state of use thereof.

A terminal unit 2 is provided to allow terminal connection with a data input / output terminal provided on the bottom of a wireless mobile phone for data communication with an external device. In addition, fixing means (not shown) are provided on the terminal part so as not to be arbitrarily spaced apart in the state where the terminal is connected. The main body 4 of the adapter 1 incorporates a Bluetooth chip (circuit) which is a short range wireless communication module. After connecting the adapter 1 to the mobile telephone 6 as shown in Fig. 2, the user can perform wireless data communication with an external device such as a notebook computer or a PDA.

3 is a perspective view of an adapter connected to a PDA (Personal Digital Assistant) as another embodiment of the present invention. The illustrated adapter 1 'is a card type, and the main body 4' has the same form as a PC card conforming to the standard of the conventional CF or PCMCIA (Personal Computer Memory Card International Association). A terminal portion 2 ', which can also be connected to a data input / output terminal portion of a PDA (not shown), is provided at one side, and a Bluetooth chip is embedded therein. As a result, the information of the PDA can transmit and receive data to and from other remote systems using a mobile telephone as a relay. The adapter in this embodiment is provided in a card form.

Another embodiment of the present invention is shown in FIG. 4. 4 is a perspective view of an adapter 1 'for a notebook computer (not shown). The main body 4 'is also in the form of a card according to the PCMCIA standard as described above. The adapter has a built-in Bluetooth chip, the handle portion 10 is provided on one side for easy detachment, and the terminal portion 2 'for the terminal connection in the front. The handle portion 10 is an extension of the main body, and can incorporate a predetermined circuit.

As a result, users of information devices such as mobile phones, PDAs, and notebook computers having conventional specifications can perform data communication with peripheral devices without having a terminal cable, and furthermore, a new technology Bluetooth can be used. will be.

As such, the concept of the present invention may be implemented in various types of adapters, but the basic configuration thereof is the same.

According to the above configuration, the user can utilize the technology by simply inserting the adapter even in the old model without the Bluetooth chip, which is a newly developed short-range wireless data communication module, so that a user does not have to purchase a mobile phone, a notebook computer, a PDA, or the like. Become economically beneficial.
