Portable computer for infrared data communication

Abstract

A portable computer with infrared data communication capabilities is disclosed. The computer has an infrared transceiver capable of enlarging the data sending / receiving angle and reliably performing radio data communication with another electronic appliance. The computer also has a selection circuit capable of activating all light elements during a data sending operation or selecting one active light receiving element from a plurality of light receiving elements during a data receiving operation, thus performing a reliable infrared data communication. In the computer, an opening is formed on an outside edge of the display body. Both an infrared data sending unit, consisting of at least one light element, and an infrared data receiving unit, consisting of at least one light receiving element, are commonly carried on a circuit board set in the opening of the display body.

Description

CLAIM OF PRIORITY[0001] This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. .sctn. 119 from an application entitled portable Computer For Infrared Data Communication earlier filed in the Korean Industrial Property Office on Oct. 17, 1997, and there duly assigned Serial No. 97-53475, a copy of which is annexed hereto.[0002] 1. Technical Field[0003] The present invention relates to a portable computer with infrared data communication capabilities, and more particularly to a portable computer provided with an infrared transceiver capable of reliably performing radio data communication with other electronic devices.[0004] 2. Related Art[0005] As well known to those skilled in the art, several techniques have been developed and proposed to allow users to more effectively use electronic devices. Particularly, developments in radio communication techniques allow a variety of electronic devices to perform radio data communicati...

Benefits of technology

[0015] Another object of the present invention is to provide a portable computer, which is provided with a selection circuit capable of activating all light elements during a data sending operation of the computer or selecting one active light receiving element from a plurality of light receiving elements during a data receiving operation of the computer, thus performing a reliable infrared data communication.

Problems solved by technology

However, when the modules of the infrared transceivers are placed on positions remarkably diverged from reference positions to the left or right, it is almost impossible to match the data sending / receiving modules of electronic appliances within an effective data communication region.

Therefore, the known infrared transceivers are not effectively used with electronic appliances used in offices where it is almost impossible to match the direction of the data sending / receiving modules of the appliances or limit the distance between the modules.

Particularly, due to the above problems experienced in known infrared transceivers, it is very difficult to match the direction of the data sending / receiving modules of electronic appliances or set the distance between the modules in the case of desktop or portable computers.

Therefore, when it is necessary to send or receive data between a main computer and a plurality of desktop or portable computers, the desktop or portable computers, laid on tables or desks arranged along several rows, may fail to effectively perform infrared data communication with the main computer.

While these recent efforts provide advantages, I note that they fail to adequately address how a portable computer can be provided with an infrared transceiver capable of efficiently and reliably performing radio data communication with other electronic devices.
