Patent ID: 8348366

Claim:
A wiring board comprising: a board; a plurality of ICs mounted on the board and specifications of the ICs being the same; a plurality of wires provided on the board and transmitting respectively, to the ICs, a plurality of mode selection signals respectively corresponding to a plurality kinds of process modes whose contents of a process differ from each other; and a signal selection part provided on the board, selecting one from the plurality of mode selection signals transmitted through the plurality of wires and then outputting the selected mode selection signal to each IC, wherein each IC has a processing part selecting one from the plurality kinds of process modes according to the mode selection signal inputted from the signal selection part, and then performing the selected one kind of process mode, each IC includes a plurality of first input terminals connected respectively to the plurality of wires and a second input terminal provided apart from the plurality of first input terminals and outputting to the processing part the mode selection signal inputted from the signal selection part, the plurality of mode selection signals respectively corresponding to the plurality kinds of process modes are inputted from the plurality of wires to the plurality of first input terminals, respectively, and the signal selection part connects one of the plurality of first input terminals provided in each IC, to the second input terminal, according to a position in which the IC is mounted on the board.
