CONTROL CIRCUIT BOARD AND ROBOT CONTROL DEVICE

A control circuit board 1 includes a first and second elements 5, 6 on each surface of a board member 4. The first and the second elements 5, 6 respectively have first and third edge portions 9, 11 which are opposite to each other and second and fourth edge portions 10, 12 which are opposite to each other. A plurality of signal input pins I1 to I5 are provided to the first edge portion 9, a plurality of signal output pins O1 to 05 are provided to the third edge portion 11, a plurality of between-element communication input pins A1 ˆ¼ to A5 are provided to the second edge portion 10, and a plurality of between-element communication output pins B1 to B5 are provided to the fourth edge portion 12, respectively. A common signal is input to the first and second elements 5, 6 and a communication is performed between the first element 5 and the-second element 6. Loss of control function can be surely prevented while suppressing enlargement of the board and increase of development/production cost.
