CONTROL PANEL

PROBLEM TO BE SOLVED: To provide a control panel wherein its depth is made reducible and its manufacturing processes can be simplified and the dimensions and shapes of the respective units used in it are unified and its areal utilization factor are improved. SOLUTION: A control panel 21 comprises a panel main body 38 and a protective cover mounted on the rear side of the panel main body 38. In the panel main body 38, there are combined with each other in a planar way a variety of units U comprising dummy units 36, 37 in addition to such necessary units for the controls, etc., of the external apparatuses of the controlled system of the control panel 21 as a display input unit 23, a plurality of input units 25, 27, 29, 31, 33, and a communication unit 35. While the respective units U are so made into blocks that they can be combined with each other via their mutual engagement grooves, their planar shapes observed from the front side of the panel main body 38 are made rectangular to make substantially the dimensions of the two sides of each rectangular unit integral times as large as its predetermined reference dimensions. Also, the electrically connective portions of the respective units U are provided on the rear side of the panel main body 38.
