PROBLEM TO BE SOLVED: To provide a card position detection method and a card reader for detecting a position of an inserted card without installing a component (mechanical sensor) leading to cost up even if inconvenience to detect the position of the inserted card on the basis of a light emitting and light receiving element is generated, and consequently performing appropriate transmission and reception of data. SOLUTION: The card reader detects the position of the card by suing magnetic circuit noise based on the electric noise generated when the card in a card conveying path 2 contacts or separates with and from a magnetic head 7, without depending on a card position detection sensor such as a photosensor composed of a light emitting and receiving element 6d.
