Abstract

PURPOSE:To simplify the wiring work and to decrease the number of connection circuits, by connecting the series circuit between the diodes and loads at the cross points of matrix and controlling the load through the selection of row and column. CONSTITUTION:The series circuits of 16 sets in which 16 sets of diodes D and display lamps PL are connected in series one by one, are connected between the address line AL at row side and the address line DL at column side at each cross point of the matrix by one circuit. When the controller 4 selects the address lines AL and DL, the display lamp PL at the cross point only is illuminated and others are kept distinguished. The controller 4 has 16 sets of the sensors S at the input and the pilot lamp corresponding to each sensor depending on the output of each sensor S is lighted by sequentially scanning the sensor S in circulation.
