<p>PCT No. PCT/JP85/00669 Sec. 371 Date Aug. 4, 1986 Sec. 102(e) Date Aug. 4, 1986 PCT Filed Dec. 5, 1985 PCT Pub. No. WO86/03611 PCT Pub. Date Jun. 19, 1986.An optical type record card reader according to the present invention is provided with a line sensor (10) for reading an information by a reflected light from a track of an optical type record card (1) irradiated by a light source (4) and in which optical type record card an information is recorded on a record medium (1A) as a plurality of parallel tracks which can be read out optically, a cylindrical lens (11) located rotatably between the optical type record card (1) and the line sensor (10) and an azimuth error detecting circuit for detecting an azimuth error generated between the track and the line sensor (10), wherein the cylindrical lens (11) is rotated by the detected output of the azimuth error detecting circuit to thereby correct the azimuth error. Thus, it becomes possible to correct the azimuth error of the projected image a sub-track of the optical type record card onto the line sensor smoothly, highly precisely and rapidly by the rotation of the cylindrical lens.</p> |
