OPERATION DISPLAY AND PANEL FACE UNIT

PROBLEM TO BE SOLVED: To provide an operation display having consistency among panel face apparatuses and the utilizing efficiency of its area is excellent. SOLUTION: Each of surfaces S of respective panel face units 24a-24d constituting an operation display panel 20 is formed in a rectangular shape the lengths of whose two sides are made m1.L×m2.L (L is a reference dimension, and m1 and m2 are positive integers). Arranging the respective panel face units 24a-24d so that their surfaces S are made adjacent to each other, a whole surface AS of the operation display panel 20 uniting the surfaces S of the respective panel face units 24a-24d is formed in a retangular shape the lengths of whose two sides are made n1.L×n2.L (n1 and n2 are positive integers). Normalizing the shapes and dimensions of the panel face units, a plurality of panel face units 24a-24d can be arranged regularly without any clearance to improve their operabilities and visibilities. Also, being integrated designedly too, the panel face units 24a-24d become beautiful visibly.
