Abstract
Abstract A reader/writer apparatus for an optical memory card (C) for reading and/or writing data with respect to the optical memory card (C) having a data storing face, which apparatus comprises a card holder including a carriage (20) carrying and holding the card (C) inserted and transporting the card to a reading or writing position and a feeding mechanism (10) for driving the carriage (20). The reader/writer of the present invention may further comprise an optical waveguide holder (33) holding an optical waveguide (32), which is connected, at a base end thereof, to the light emitting and receiving section (31) of a reading head, so that another end of the optical waveguide may oppose a data recording face of the optical memory card (C). The waveguide holder (33) is moved independetly of the movement of the card holder. The reader/writer apparatus of the present invention may further comprise a regulating member (50) for regulating the angular position of the card (C). With the arrangement, the reading and writing can be effected accurately with respect to an optical memory card (C) of a high density storage. The apparatus may further include a dust removing device (70, 80).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
54 words
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 carriage carrying and holding the card inserted and transporting the card to a reading and/or writing position; and a feeding mechanism for driving the carriage.
Claim 2
Dependent Claim
54 words
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 carriage carrying and holding the card inserted and transporting the card to a reading and/or writing position; and a feeding mechanism for driving the carriage.
Claim 3
Dependent Claim
115 words
A reader/writer apparatus for an optical memory card 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
61 words
A reader/writer apparatus for an optical memory card according to claim 1, which further comprises a card holder including a regulating member provided so as to extend from the reading and/or writing position to a card inserting opening and to abut against one side of the card carried and held by the carriage for regulating the angular position of the card.
Claim 5
Dependent Claim
111 words
A reader/writer apparatus for an optical memory card 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 card so that the data storing face of the card may face downwardly; an air blowing nozzle provided within the housing so as to face the data storing face of the 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 card held by the carriage.
