PROBLEM TO BE SOLVED: To permit easy detachment of an indication panel, attached to an operation panel frame with an adhesive agent, by providing a notch, deeper than a bonding surface, at least not less than one place on the end part of the bonding surface between parts. SOLUTION: A display panel 16 is a plate type panel made of a resin and is provided with switch buttons and display units on the surface of the same. An operation panel 15 for fitting the display panel 16 is provided with a rectangular parallelepiped configuration and a recessed part 25 is provided at the central part of the same so as to permit the fitting of the display panel 16. The bottom area of the recessed part 25 is designed so as to be wider than the surface area of the display panel 16. The depth of the recessed part 25 is deeper than the thickness of the display panel 16 while the rear surface of the display panel 16 is attached to the recessed part 25 of the operation panel frame 15 through a bonding surface 16a, on which the adhesive agent is applied. In this case, fixing can be effected through screwing or simple fitting method. The outer peripheral guide frame 15a of recessed part 25 of the operation panel frame 15 is provided with a notch 15b, whose depthαis deeper than that of the bonding surface 16a of the display panel 1b.
