PROBLEM TO BE SOLVED: To improve operability of a touch sensor type button in the increase in size of a display part.SOLUTION: An operation display part 120 is constituted in such a manner that a square cylinder-shaped rib 131 extends toward a back surface side from a rectangular opening 133 provided at substantially a center part of a step part 132 of an operation display part housing 130, on the outer peripheral side of the square cylinder-shaped rib 131, a circuit board 150 is disposed which has a touch sensor type button conductive surface 151 in a gap formed between a rear surface side of the step part 132 and a device non-display part 142 of a display device 140, and a conductivity capacitance circuit is formed by the conductive surface 151 and a grounding wire by coming into contact with an operation unit 162, and selection, setting and display of a mode such as an operation course and the like and each function are performed. Thus, an interval between the touch sensor type operation unit 162 for performing selecting, setting of the mode such as the operation course and the like and each function and a display window 161 for displaying the setting content can be reduced, so that operability of the button can be improved even when the size of the display window 161 is increased.SELECTED DRAWING: Figure 1 |
