CONSTITUTION: A dial board 16 to be an operation member 15 set up on the mounting face 26a of a mounting board 26. The mounting face 26a is provided with three-dimensional inclination inclined from a corner part A most separated from an operator's left hand for operating a dial 14 to a corner part C most close to the left hand downward in both the vertical and horizontal directions. Since the surfaces of the operation parts of respective dials 14 on the dial board 16 are formed along the inclination, the operation parts of the dials 14 can be operated by comfort posture and fatigue due to long work can be reduced.</p> |
