PURPOSE:To enable skew angle correction by a simple mechanism by providing a circular recessed part at the central part of one side parallel to the track of an optical card and finely rotating the card while sliding and contacting the recessed part to a cylindrical member having the same diameter as a recessed part provided on an optical card loading stand. CONSTITUTION:At the central part of one side parallel to a track 7 of an optical card 1, a recessed part 3 forming one part of a circle is formed. Then, this recessed part 3 of the card 1 is slid and contacted to the cylindrical member having the diameter equal to the recessed part 3 provided on the optical card loading stand. By finely rotating the card 1 forward and back ward, the central point of the cylindrical member is turned to the center of skew angle correction. Thus, without increasing the volume or weight of th skew angle correcting mechanism, the skew angle of the optical card can be corrected while taking the central part of the recessed part as the central point of the skew angle. |
