Abstract

PURPOSE:To obtain a specified signal transmitting device with which no increment is required for the number of the specified signal detecting parts regardless of an increment of the number of slave stations, by providing a specified signal selective scanning parts having a scanning means to the transmission lines connecting the master station to plural slave stations. CONSTITUTION:The state of designation is detected at slave stations 11-1n, and the specified signal is transmitted through transmission lines 21-2n. These lines are connected to each input terminal of a specified signal selective scanning part 7, and the part 7 works independently from a station selective scanning part 4 to give a successive and periodic switching to each transmission line to connect the transmission line to a specified signal detecting part 6. The part 6 detects whether or not the specified signal is transmitted via a connected transmission line. Accordingly the specified signals sent from all slave stations are detected through just a single detecting part 6.
