Abstract: A slot machine of the type having a number of drums, an actuating lever, a kicker, a drum rotating mechanism, detecting mechanism for detecting any hit mode and a coin discharging mechanism. An actuating frame and a kicker engaging with the hook of the actuating lever are formed as different bodies. When the kick projections of the kicker hit the ridge of an index notched disk provided on the drum, it is allowed to escape in the reverse direction at once. The kicker is adapted for energizing operation when each kick projection enters a notch of a corresponding notched disk, whereby the kick projections are protected from excessive loading. Moreover, when the rotary drums are stopped, the hit mode according to the permutations displayed on the rotary drums is automatically detected.
