Summary1,413 words

#The present invention generally relates to a data transfer control unit and method therefor, and more particularly to a method and data transfer control unit for transmitting data using infrared (IR) rays or the like.

#Hitherto the invention, a data transfer control unit using IR rays has been employed in small electronic equipment such as an electronic notebook, a pocket computer, a radio selective calling receiver and the like. Generally, the input buttons and the display screen of such small electronic equipment are small in proportion to the main chassis/body of the equipment, and it is cumbersome to input thereto a large quantity of data, especially if the user's fingers are large in comparison with the input buttons.

#Therefore, users typically input data to other electronic equipment such as a personal computer or the like, and then transfer the data to the small electronic equipment from the personal computer by infrared rays.

Brief description of the drawings16 figures

#The foregoing and other objects, aspects and advantages will be better understood from the following detailed description of a preferred embodiment of the invention with reference to the drawings, in which:

#FIG. 1 illustrates an example of electronic equipment to which a data transfer control unit according to the present invention is preferably applied;

#FIG. 2 is a functional block diagram showing the data transfer control unit according to the present invention;

Detailed description5,740 words

#Referring now to the drawings, and more particularly to FIG. 1, which illustrates exemplary electronic equipment to which a data transfer control unit and method according to the present invention is applied, an infrared (IR) ray sending/receiving window 3 is provided in first and second electronic devices 1, 2. It is noted while IR rays are used for the data transfer medium, electromagnetic waves (e.g., radio frequency) and wire communications also may be employed (alternatively or additionally).

#An infrared ray emitter (not illustrated) and an infrared ray receiver (not illustrated) are provided inside the infrared ray sending/receiving window 3 of each of the electronic devices 1, 2, the circuitry of which is known by one ordinarily skilled in the art. In FIG. 1, the first electronic device 1 and the second electronic device 2 are, for example, a radio selective calling receiver and a mobile telephone, respectively.

#An infrared signal generated by the emitter of the first electronic device 1 is received by the receiver of the second electronic device 2. Conversely, an infrared signal generated by the emitter of the second electronic device 2 is received by the receiver of the first electronic device 1. Thus, communication therebetween is achieved.
