<p>PURPOSE:To remove the generation of a trouble due to defective contact by transmittng/receiving information between a card and terminal equipment on the basis of photocoupling. CONSTITUTION:When an memory card device 101 is inserted from an inlet A of terminal equipment, the card 101 is coupled with the terminal equipment on the basis of the operation of an idler 302. Light emitting systems 310-312 and photodetecting systems 307-309 to transmit/receiver information between the card device 101 and the terminal equipment are descended on the surface of the card device 101 by idlers 305, 306. Simultaneously, laser light is irradiated from a laser light source 304 to a solar battery part on the card device 101 through a lens system 303. Consequently, powe is supplied and information is transmitted/received between the card device 101 and the terminal equipment on the basis of photocoupling.</p> |
