Since the monitor for displaying images is arranged at a position where it can be seen from the operation position of the operation unit, the operator can confirm the visual confirmation corresponding place where visual confirmation is required by the monitor. It is not necessary to move from the operating position of the operation unit, and it is not necessary to move from the operation position of the operation unit at any place where frequent visual confirmation is required. In addition to being reduced, the imaging device can be placed inside the machine cover. It can be, there is an advantage that it is possible to improve the workability.

  Furthermore, since the image pickup device for picking up the place corresponding to the visual confirmation is arranged, there is an advantage that even if the place is difficult to see, if there is a space for placing the image pickup device, it can be confirmed without any trouble.

  In addition, if the location where visual confirmation is required is a place where visual confirmation is required during setup adjustment, setup adjustment can be performed by operating the operation unit while looking at the monitor screen during setup adjustment. There are advantages.

  Furthermore, if the location where visual confirmation is required is the location where visual confirmation of the processed wire is required when the wire processing machine stops in error, the error status can be confirmed on the monitor screen when the error stops, and the countermeasures There is an advantage that can be done quickly.

  In addition, if the imaging device has a CCD camera structure, the CCD camera is small, so even if the installation space is quite small, it can be arranged so that it can be imaged from a desired direction, and more accurate images can be obtained. There are advantages.
