Abstract

PURPOSE:To restore a magnetic card reader to an operating state again by providing a reset mechanism to reset an abnormal operation such as the stall of a microprocessor. CONSTITUTION:A host device interface circuit 26 performs control and data transmission/reception between the host device and a magnetic card reader. A magnetic card reader control circuit 24 incorporates the microprocessor and performs the editing processing such as the code conversion of the recognition result of a magnetic card recognizing circuit 23. A hardware HW reset mechanism 28 is added to the magnetic card reader constituted in this manner to reset the abnormal operation such as the stall of the microprocessor. Thus, when the circuit 24 enters into the stall state because of an external noise or the like and input from an operator to the magnetic card reader is impossible, the magnetic card reader is restored to the operating state again before the operator finds this stall state.
