摘要：
本发明的课题为以高SN比检查电梯等的钢丝绳的劣化。本发明的绳索检查装置(1100)具有产生互为反向的交流磁场的振荡线圈(1)和振荡线圈(2)、在它们的中间或其附近在检查对象即钢丝绳的周向上错开地配置的多个接收线圈(1)～(16)和切换多个接收线圈(1)～(16)的动作的切换部。
摘要（英）：

The object of the present invention is to check the deterioration of a steel wire rope such as an elevator with a high SN ratio. The rope inspection device (1100) of the present invention has an oscillation coil (1) and an oscillation coil (2) for generating an alternating magnetic field which is opposite to each other, a plurality of receiving coils (1) to (16) arranged in the middle or the vicinity of the oscillation coil (1) and the oscillation coil (2) in a staggered manner in the circumferential direction of the inspection object, and a switching section for switching the operation of the plurality of receiving coils (1) to (16).
