Abstract

PURPOSE:To make a light regulation level of illumination loads modifiable with simple composition and manipulation by equipping an information changing means in which information of light regulation levels is changed every illumination loads in memory means. CONSTITUTION:When data of light regulation levels memorized in a memory means 18 are modified, a modification command switch 25 is first turned on so that a memory means 18 related with illumination loads 14 corresponding to input/output lines ei and fi in a level memory part 13 is interrupted from a light regulation level setting part 11. Next an operation changeover switch 24 is turned on or off so as to select either addition or subtraction of a counter 23, and a load command switch 21 is turned on so that the counter 23 starts an operational action selected. A counting result of this counter 23 is fetched to the memory means 18 at the timing when the load command switch 21 is turned off. Accordingly data of the light regulation levels can be easily modified in this way every illumination loads 14.
