| Zusammenfassung: | A card reader may include a main body part having a conveyance path; a first card detection mechanism disposed upstream of the main body part; a second card detection mechanism disposed in the main body part at a distance less than a length of the card from the first card detection mechanism; a shutter member disposed between the first and second card detection mechanisms; a shutter state detector; and a control unit. The control unit may be structured to close the shutter member when an object is detected by the second card detection mechanism after being detected by the first card detection mechanism, and then the inserted object is not detected by the second card detection mechanism while the inserted object is not detected by the first card detection mechanism; and detect that an object other than the card has been inserted when the shutter member close after the control. |
