Abstract: An automatic vending machine comprises a plurality of electric lamps arranged geometrically on a front panel of a housing and a lamp control circuit for lighting the lamps successively and repeatedly in response to a signal which is generated in accordance with a vending operation of the machine. The lamps are arranged equidistantly along a circle and thus a light spot appears to rotate along the circle. In a preferred embodiment the lamp control circuit comprises a lottery circuit which produces a winning signal for discharging an extra article as a free addition and at the same time the light spot is stopped at a predetermined lamp having a lucky number applied thereto.
