An elevator cage control apparatus includes a brake coil energized and deenergized by start and stop command signals to move and restrain the cage, respectively. A current detector detects current flowing through the brake coil. A counter counts a time interval beginning at generation of the stop command signal and ending when current in the brake control gradually decreasing increases instantaneously and a time interval beginning at generation of the start command signal and ending when current in the brake coil gradually increasing decreases instantaneously. A memory stores the counted time intervals. A drive command issuer commands a motor driving circuit to stop and start the cage, after the counted time intervals stored in the memory have lapsed, respectively.
