Abstract
A reader-writer apparatus for an optical memory card for reading and/or writing data with respect to the optical memory card having a data storing face, which apparatus includes a card holder including a carriage for carrying and holding the card inserted thereon and transporting the card to a reading or writing position and a feeding mechanism for driving the carriage. The reader/writer in another aspect of the present invention includes an optical waveguide holder holding an optical waveguide, which is connected at a base end thereof to the light emitting and receiving section of a reading head, so that another end of the optical waveguide may oppose a data recording face of the optical memory card. The waveguide holder is moved independently of the movement of the card holder. The reader/writer apparatus of the present invention has a regulating member mounted to a stationary portion of the apparatus for regulating the angular position of the card so that reading and writing can be effected accurately with respect to an optical memory card of a high density storage. The apparatus may also include a dust removing device.
