Abstract

PURPOSE:To enable to perform matrix distribution to the matrix used by other similar frames, for the drive circuit corresponding to the matrix section not used, when a part of the matrix sections given to a frame is used. CONSTITUTION:The jumper connections 11, 12 are provided for the frames A and B respectively. In the conection 12, the direct connection shown in dotted lines for normal eight lines is changed to the connection shown in solid lines which connect the upper and lower two lines. With this connection, the drive line which is branched into two via the connections 11, 12 is connected for one to the matrix circuit 3o and for another to 3o'. Further, the matrix 4o' and 4o are vacant lines and the units corresponding to those can be extended. That is, when only a part of the matrix given to a frame is used, the drive circuit corresponding to the matrix not used is changed for the connection with the jumper to the matrix used for other similar frames, allowing to distributematrix.
