Card processing apparatus and automatic transaction machine

Abstract

A card processing apparatus includes a card insertion opening, and a card insertion detection sensor. A magnetic card is to be inserted in the card insertion opening. The card insertion detection sensor is configured to detect the magnetic card inserted in the card insertion opening. A magnetic head is provided near the card insertion opening and is configured to detect a change in an electromagnetic field and output a magnetic signal. A control unit is configured to: receive the magnetic signal from the magnetic head when the card insertion detection sensor detects the magnetic card; receive magnetic signal from the magnetic head when the card insertion detection sensor does not detect the magnetic card; acquire the magnetic signal when the magnetic signal includes a predetermined pattern; and discard the magnetic signal when the magnetic signal does not include the predetermined pattern.
