摘要

Electromechanical apparatus simulator of the game of tennis, essentially characterized in that it comprises an optical screen in which the limits of a tennis court are represented, an optical device producing the image of a ball on said screen, operated in such a way that the aforementioned image moves alternately from one end to the other, exceeding the limits of these; producing optical devices on the screen of representative images of two tennis rackets, each device being associated with mechanisms operable by respective players to move said images within corresponding areas of the field; end of stroke means that detect when the image of the ball detects the extreme limits of the field, generating in response an electrical signal of step by step advance of a counter of many corresponding to the player of the opposite extreme limit; devices comparators of the transverse position of the image of the ball in the field with the transverse position of each one of the rackets, and electrical connection means that inhibit the excitation of the counters so many devices when there is coincidence of position between the images of the ball and the racket corresponding to the area of opposite field.
