セットする作業も容易になるという効果が期待できる。The cable outer diameter measuring device of the present invention described above comprises an air wiper for blowing air onto the outer peripheral surface of the cable and an outer diameter measuring device for optically measuring the outer diameter facing the side surface of the tube. Since the multiple nozzles are placed close to each other so as to sandwich the outer diameter measuring device when viewed in the traveling direction of the cable, the outer diameter can be measured at the same time as the dust particles that have adhered to the outer peripheral surface of the cable are blown away. No measurement error occurs. In addition, the air wiper can also remove the floating dust and the like adhering to the front of the outer diameter measuring instrument.
The sensitivity of the device can be kept high. Further, since the air wiper and the outer diameter measuring device are incorporated in one supporting frame, it is possible to expect an effect that the appearance is simple and that the work of setting the cable for the preparation for manufacturing becomes easy.
