To provide an operation control system for game house store equipment with which the game house store equipment is efficiently operated with reduced waste power consumption to save electric power charge.

When the operations of store equipment 5, 6 arranged in a game house 1 with a plurality of game machines 2 arranged therein are controlled, the number of machines 2 under operation at the point of present time is detected and the operations of the equipment 5, 6 are automatically controlled based on the number of detected machines. Thus, the house equipment 5, 6 are efficiently operated resulting in suppression of waste power consumption. Consequently, energy is saved and electric power charge is reduced in the game house.
