Card processing apparatus and data reading device

摘要

A card processing apparatus (100) is provided with a card insertion detecting unit (7) arranged in a magnetic head (70). The card insertion detecting unit (7) includes a reading unit (71) for reading magnetic data recorded on a magnetic card (160), an output unit (74) for outputting a signal read by the reading unit (71), and an output control unit (73) for controlling whether or not to output the signal read by the reading unit (71) from the output unit (74). When the magnetic card (160) is inserted, since only a reproduction signal for the preamble part of the magnetic data is output from the output unit (74), a body part of the magnetic data is prevented from being illegally acquired.
