PROBLEM TO BE SOLVED: To surely evade a dangerous state by entirely inhibiting the operation of a sewing machine in the dangerous state that a child approaches the sewing machine freely when an adult is not near the sewing machine. SOLUTION: The identification information of a radio IC tag provided in portable terminal device approaching the sewing machine is read by an RFID reader (S11), and in the case that the read identification information is accurately received (S12:Yes) and in the case that it is the identification information for permitting the operation of the sewing machine (S13:Yes), an operation permission mode is set (S14). However, when a mother leaves the sewing machine (S12:No) or when it is the identification information for inhibiting the operation of the sewing machine (S13:No), an operation inhibition mode is set (S15).
