Abstract: Automatic ball-starting device of football game table, including multiple ball-guiding tubes and a controlling box. Two ball-guiding tubes respectively extend from two goals on two sides of the football game table to the controlling box disposed at the center thereof. The ball-guiding tubes are communicated with a ball-striking chamber of the controlling box. A ball-striking tube is connected with the ball-striking chamber and extends to a middle portion of the face of the football game table. Two controlling buttons extend from the controlling box to two sides of the football game table. A controlling circuit is disposed in the controlling box for detecting whether there is a ball in the ball-striking chamber. If so, a speaker is driven to emit a message to remind the players. After either of the controlling buttons is pressed, after a delay of several seconds, the controlling circuit is closed to power on the driving coil.
