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 comprises a card holder including a carriage carrying and holding the card inserted and transporting the card to a reading or writing position and a feeding mechanism for driving the carriage. The reader/writer of the present invention may further comprise 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 car holder. The reader/writer apparatus of the present invention may further comprise a regulating member for regulating the angular position of the card. With the arrangement, the reading and writing can be effected accurately with respect to an optical memory card of a high density storage. The apparatus may further include a dust removing device.
