Apparatus for detecting inclination of an optical card |
摘要 |
The present invention relates to an optical card reader that detects any relative inclination of the card by measuring the relative motion of the optical tracks themselves. The optical card reader comprises a card holding portion, an optical head having the ability follow data tracks on the optical card, and a detector that measures the angle of inclination of the optical card from a tracking signal generated from a one-dimensional relative movement of the card holder and the optical card.
