A reading device for reading data from an optical card having a unit reading column in which a plurality of data pits are arranged in a row, comprising: a light source that generates a reading light beam; an objective lens for condensing light onto the optical card; supporting means for supporting the optical card substantially on the front focal plane of the objective lens; a rotating mirror that is rotatable about a rotating axis passing through a point located away from the optical axis of the objective lens and oriented in a direction perpendicular to the column direction of the unit reading column on the optical card; Scanning means for rotating the rotating mirror so that the light beam reflected by the rotating mirror scans data pits on the unit reading row on the optical card via the objective lens. and a light receiving means for detecting light from a data pit scanned by the light beam. 2. Utility model registration claim 1, characterized in that the light-receiving means includes a light-receiving element and an optical system that is provided beside an objective lens and focuses light from a data pit onto the light-receiving element. data reader for optical cards. 3. The optical card data reading device according to claim 2, wherein the optical system is a convex lens that shares a central plane with the objective lens. 4. The optical card data reading device according to any one of claims 1 to 3, wherein the light source emits a laser beam.
