PURPOSE:To increase the reliability by simplifying the circuit through the provision of the interlock function between a pair of drive lines and its drive circuit. CONSTITUTION:The matrix circuit cinsists of the X drive lines X1-Xm, interlock circuit 3 connected to m lines of drive lines, drive lines X1'-Xm' connecting the circuit 3 to the circuit 1, Y drive lines Y1-Yn, drive circuit 1, loads L1,1-Lm,n and reverse block diodes D1,1-Dm,n. The interlock circuit 3 has the constitution that interlocking contacts ry1-rym operated with the relay coil is connected between the drive lines X1'-Xm' and the X drive lines X1-Xm. |
