BRIEF SUMMARY
DESCRIPTION
1. Technical Field of the Invention
The present invention relates to a slot machine wherein a game medium is inserted into a slot and wherein the changing patterns of pattern indication means are stopped by manipulating stop switches.
2. Background of the Prior Art
A conventional slot machine of the specified type is such that, after a game medium such as a gaming medal or coin has been inserted into a slot, a game initiation lever is manipulated to rotate three drums bearing the indications of pictures. Push-button stop switches mounted on the body of the slot machine are successively depressed to stop the rotations of the drums, and a predetermined number of game media are awarded as a prize in accordance with the combination of the stopped indications (refer to the official gazette of Japanese Utility Model Registration Application Laid-open No. 130590/1979).
The prior art, however, has the problem that, since means for stopping the rotations of the drums is the system of depressing the stop switches aligned on the body of the slot machine, the stopping operation holds little interest, so game players become tired of the slot machine game easily.
The present invention has been made in order to solve the above problem, has for its object to provide a slot machine which can increase the interest in a game owing to an interesting method of operation.
DISCLOSURE OF THE INVENTION
To the accomplishment of such an object, according to the present invention, there is provided a slot machine wherein a plurality of patterns are changed by inserting a game medium into a slot and manipulating a game initiation switch, and the respective patterns are stopped at stop timings selected by manipulating a stop switch. The slot machine is characterized by comprising a handle which includes the game initiation switch and the stop switch.
Such a slot machine may well be so constructed that the game medium includes at least two sorts consisting of a minimum medium unit, and a multiple medium unit which has a value corresponding to a plurality of such minimum medium units. Also, identification devices are comprised for the game medium units inserted into the slot, wherein games which conform to, at least, the values of the game medium units identified by the identification devices can be played.
Further, according to the present invention, there is provided a slot machine wherein indications of a plurality of pattern indication means are changed by inserting a game medium into a slot and manipulating a game initiation switch, and the changes of the respective indications are stopped at stop timings selected by manipulating the stop switches. This slot machine is characterized by comprising identification devices for units of the game medium inserted into the slot, sum value storage means for summing value numbers of the game medium units identified by the identification devices, and for storing the sum value number and means for setting the value number of the game medium unit to be spent on one game. The machine also comprises a stake selection value display portion which displays the value number set by the setting means, value subtraction means for subtracting the value number set by the setting means, from the value number stored in the sum value storage means, in response to the manipulation of the game initiation switch and start means for bringing the game initiation switch into a manipulatable state on condition that the game medium unit has been identified by the identification device and that the value number has been set by the setting means. The machine further comprises reward judgment means for judging whether or not a combination of the respective indications after the stop of the changes is a prize awarding combination, prize value storage means for storing value numbers of prizes beforehand, prize value selection means for selecting any of the value numbers of the prizes stored in the prize value storage means, in conformity with the prize awarding combination judged by the reward judgment mea
