<p>PURPOSE:To avoid the trouble of signal line wiring work by automatically connecting a signal line to a terminal circuit in a printed board package mounted on the final position out of plural printed board packages of the same kind for duplexly connecting signal lines. CONSTITUTION:Each of plural printed board packages 2a to 2n of the same kind for duplexly connecting signal lines identifies whether the package itself is mounted on the final position or not by receiving information outputted from a mounting display circuit 8 in the succeeding package by a mounting position identification circuit 7, and only when the package is mounted on the final position, automatically connects a signal line 4 to a terminal circuit 3. Even when the number of mounted printed board packages 2a to 2n is not defined, the signal line 4 can be automatically connected to the terminal circuit 3 in the printed board package mounted on the final position without a worker executes specific wiring work at the time of setting up or increasing an electronic equipment. Consequently, the trouble of signal line wiring work can be removed.</p> |
