ABSTRACT:
Apparatus for infrared communication between a first electronic device (10, FIG. 7) such as a notebook computer which has a slot (84) for receiving an IC card, and a second electronic device (104) such as a computer, printer, etc. that has an infrared transmit/detect unit (100) (or another notebook computer with a slot). The apparatus includes an IC card (82) with a rigid frame (112, FIG. 8) having a front portion (114) that holds a connector (88), the frame having a rear portion (116) that projects rearwardly from the slot and that holds an infrared emitter (120) and an infrared detector (122). As a result, the first electronic device fixes the position and orientation of the emitter and detector. The IC card with the emitter and detector preferably has a width (W) and thickness (T) as prescribed by JEIDA and PC CARD standards. The emitter preferably includes a plurality of emitter elements (141-144) spaced laterally along the rear end portion of the card to provide increased power in a small thickness.
