<p>To detect an incomplete connection between printed boards. A monitor signal output means (1a), which is formed on a printed board (1), outputs a monitor signal. A monitor signal receiving means (1b), which is formed on the printed board (1) or a printed board (2) connected to the printed board (1), determines whether the monitor signal outputted by the monitor signal output means (1a) has successfully been received with a desired logical value. A wire (1d,2b,1e), which strides a border between the printed board (1) and the printed board (2) at least once, conveys the monitor signal outputted by the monitor signal output means (1a) to the monitor signal receiving means (1b).</p> |
