Claim of US Patent No. 10,251,275

1. A control circuit board which is to be incorporated in a robot control device, comprising:a board member; and
a first element and a second element, the first and second elements provided on opposite surfaces of the board member to thereby sandwich the board member, wherein a pin arrangement of the first element is the same as a pin arrangement of the second element,
wherein the first element and the second element respectively have a first edge portion and a third edge portion which are opposite to each other and a second edge portion and a fourth edge portion which are opposite to each other,
wherein, for each of the first and second elements, a plurality of signal input pins configured to receive signals are provided to the first edge portion, a plurality of signal output pins configured to transmit signals are provided to the third edge portion, a plurality of between-element communication input pins are provided to the second edge portion, and a plurality of between-element communication output pins are provided to the fourth edge portion, such that locations of the plurality of signal input pins, signal output pins, between-element communication input pins, and between-element communication output pins on the first element are the same as locations on the second element,
wherein, while the first element and second element are sandwiching the board member, the first edge portion of the first element is arranged directly opposite to the first edge portion of the second element, the third edge portion of the first element is arranged directly opposite to the third edge portion of the second element, the second edge portion of the first element is arranged directly opposite to the fourth edge portion of the second element, and the fourth edge portion of the first element is arranged directly opposite to the second edge portion of the second element,
wherein a common external signal is input to the first element and the second element, respectively, via the plurality of signal input pins of the first element and the plurality of signal input pins of the second element,
wherein the plurality of between-element communication input pins of one of the first element and the second element are electrically connected through the board member to the plurality of between-element communication output pins of another of the first element and the second element so that the between-element communication output pins transmit signals to the between-element communication input pins,
wherein the plurality of between-element communication output pins of the one of the first element and the second element are electrically connected through the board member to the plurality of between-element communication input pins of the other of the first element and the second element, so that the between-element communication output pins transmit signals to the between-element communication input pins, and
wherein the common external signal is output from the first element and the second element, respectively, via the plurality of signal output pins of the first element and the plurality of signal output pins of the second element.
