  By the way, when installing electronic devices such as emergency stop switches, safety switches, light curtains, and indicator lights in industrial machine systems, the safety fence frame can be drilled or a mounting bracket can be attached separately. Have to do. For this reason, it takes time to mount the electronic device, and there is a demand for a technique that allows the electronic device to be easily disposed in an industrial machine system. In addition, when the electronic device is attached to the frame, the electronic device may protrude from the frame by the size of the electronic device and get in the way of work, such as being caught by an operator's clothes.

  Also, in order to attach an electronic device to the frame, the frame must be drilled or a mounting bracket must be provided on the frame, so the mounting position of the electronic device is limited to the processing position or the mounting bracket position. There is also the inconvenience of being.

  In particular, for light curtains, various standards corresponding to safety categories are legally determined, and the dimensions and the like of the light curtain must be determined at the stage of designing an industrial machine system. Therefore, it has been difficult to cope with a sudden design change of the industrial machine system.

  The present invention has been made in view of the above problems, and includes an electronic device mounting structure and an electronic device mounting structure capable of easily and compactly arranging an electronic device in an industrial machine system. An object of the present invention is to provide an industrial machine system that can easily cope with a design change or the like.

  Moreover, the structure which the said electronic device exposes and attaches from the predetermined position of the said frame material may be sufficient (Claim 4). With such a configuration, when the electronic device is an emergency stop switch, for example, only the push button portion can be disposed so as to be exposed from the frame material, and thus the electronic device protrudes from the frame material. Can be minimized. When the electronic device is an indicator lamp or a light curtain, the indicator lamp, the light emitting element, and the light receiving element main body are housed inside the frame material, and only the light emitting part of the indicator lamp and the light emitting element and the light receiving part of the light receiving element are accommodated.
