<p>An automatic liquid soap supply apparatus comprises a plurality of sub-units (10,11,12,40,41,42) each having a use detection circuit (20,21,22,50,51,52) for detecting the use of a liquid soap supply tap (2,3,4,31,32,33) and a pump driving circuit (23,24,25,56,57,58) connected with the use detection circuit, pumps (5,6,7) each disposed to each of the sub-units, connected to each of the pump driving circuits for supplying a liquid soap to each of the supply taps and a main unit (13,43) having a single power source circuit connected with each of the use detection circuits. As an alterative to individual pumps a single pump (38) may be connected with each of the pump driving circuits for supplying the liquid soap to each of the supply taps. <IMAGE></p> |
