Abstract
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.

Claim 3
Dependent Claim
110 words
A reader/writer apparatus according to claim 1, which further comprises: a reading/writing head having a light emitting and receiving section; an optical waveguide holder holding an optical waveguide, which has a base end connected to the light emitting and receiving section of the reading/writing head, so that another end of the optical waveguide may oppose the data storing face of the optical memory card; and an optical waveguide moving/guiding mechanism for moving the optical waveguide holder in a direction perpendicular to the driving direction of the carriage, while guiding the same; said light emitting and receiving section of the reading/writing head being provided on a non-movable portion of the apparatus.
Claim 4
Dependent Claim
114 words
A reader/writer apparatus according to claim 1 which further comprises: a housing for encasing components of the reader/writer apparatus including the carriage; said carriage being adapted to hold the optical memory card so that the data storing face of the optical memory card may face downwardly; an air blowing nozzle provided within the housing so as to face the data storing face of the optical memory card held by the carriage; an air flow generating source coupled to the air blowing nozzle; a fan provided under the carriage for discharging the air in the housing; thereby to remove dust adhering to the data storing face of the optical memory card held by the carriage.
Claim 5
Dependent Claim
35 words
A reader/writer apparatus according to claim 2, wherein: said carriage is provided with a window, through which data reading or writing is carried out with respect to the optical memory card held by the carriage.
Claim 6
Dependent Claim
35 words
A reader/writer apparatus according to claim 1, wherein: said carriage is provided with a window, through which data reading or writing is carried out with respect to the optical memory card held by the carriage.
