PROBLEM TO BE SOLVED: To remotely and accurately control opening-closing of an opening-closing door of a plurality of unit lockers without causing a malfunction, in an electronic locker opening-closing control device. SOLUTION: A converting part 19 is arranged between the main control part 23 side and the two-wire type signal line 31 side, and converts a signal between a serial control signal and a differential control signal. A terminal control part 9 arranged in an individual unit locker 3 and electronically storing an identification number for identifying this locker, is connected in parallel to a two-wire type signal line 31. The respective terminal control parts 9 identify an opening-closing control signal including the identification number, transmitted in a differential control signal form via the signal line 31 from the main control part 23 side. The respective terminal control parts 9 output the opening-closing control signal to an opening-closing solenoid 11 of the opening-closing door 5 arranged in the unit locker 3 when the unit locker 3 receives the opening-closing control signal including one's own identification number.
