The tray 16 and a light-emitting device that emits light at the time of winning, a numerical display or a switch necessary for the progress of the game are provided.

In the window of the rotating drum 11, five pay lines 11b are displayed, and a bet counting display 13
When a bet count 1 is displayed on a, a win is made when a specific pattern is aligned on the center line in the horizontal direction. In the case of bet count 2, the upper and lower lines are also win lines. In the case of bet count 3, 2 The diagonal lines of the book are also added.

[0008] In addition to the coin insertion slot 1, a coin return lever 2 and a coin receiver 3 are provided on the front panel of the housing 9. Further, according to the present invention, a time interval selection switch 31 for setting a time interval for automatically stopping the rotation of each rotary drum 11 in order to a plurality of stages, for example, four stages of 1, 2, 3, and 4 seconds; A motor automatic control switch 30 is arranged to start the rotation of the game instead of the manual operation of the game start switch 14 and to automatically stop the rotation instead of the manual operation of the stop switch 15. Further, as shown in FIG. 2, the medals overflowing in the medal tray 16 or arbitrarily medals can be stored in the upper portion, as shown in FIG.
The medal mounting surface 7 has a horizontal plane and has oblique side walls 8.

The slot machine body 10 has a built-in circuit device using a microcomputer for advancing a game in response to a player's operation. That is, as shown in FIG. 3, the microcomputer in which the CPU performs the arithmetic processing according to the program stored in the memory includes the motor control means 20 for controlling the step motors 25 belonging to the rotary drum 11 and the step motors 25.
In addition to the role judging means 26 for judging the winning combination from the respective stop states, the present invention automatically stops the stepping motors 25 in sequence at time intervals according to the position selected by the time interval selection switch 31. The stop motor control means 32 and the like are configured.

The motor control means 20 rotates the three step motors 25 in response to the game start signal of the game start switch 14 and stops the motors in response to the rotation stop signal of the associated stop switch 15. At that time, a so-called pressing operation of the stop switch 15 aiming at a picture is performed by performing random number processing to generate a stop signal so as to deviate from the pressed picture in a predetermined number of picture ranges with a predetermined probability. It can also give a so-called slip. During this time, the number of drive pulses from the original position of the associated step motor 25 is counted, and the count value at the time of stop is supplied to the combination determining means 25.

The winning combination determining means 26 collates a table defining a winning combination with respect to a set of three count values in accordance with a bet signal indicating a winning line corresponding to the setting of the bet button 13, thereby obtaining a winning line 11b. It is determined whether or not any of the combinations of the above three count values has been won, and a role instruction signal is output which indicates any of the following roles: loss, big bonus, big regular, regular, and child. . At this time, the hand determination unit 26 determines that the bet button 1
If the bet count set by 3 is 2 or 3,
A determination is made for the plurality of winning lines 11b. In response to this role instruction signal, the big regular, regular and child roles are reduced in number in order to win medals, and for the big bonus, a bonus game is executed instead of immediate medal winning. In the meantime, necessary processing such as competing for the number of obtained medals is further performed.

Although the function of such a slot machine is well known, according to the present invention, the motor automatic control switch 30 is operated by the motor control means 20 by the step motor 25 while the credit is being set. Is started and restarted after the stepping motor 25 is stopped until it is operated again. Automatic stop motor control means 32
When the motor automatic control switch 30 is operated, the timer signal of the time interval set by the time interval selection switch 31 is fetched from the timer 33, and after the rotation of the step motor 25 starts, the step motor 2
5 stop signals are sequentially generated. At this time, a random number process is performed to generate a stop signal for the step motor 25 so that one of the plurality of types of patterns on the rotating drum is randomly selected and stopped at the pay line 11b with a certain probability.

The operation of the slot machine thus configured is as follows. When a medal is inserted into the medal insertion slot 12, the number of pay lines is bet by the bet button 13, and the game start switch 14 is operated, the three rotating drums 11 rotate simultaneously. When the stop switch 15 is operated in order,
The associated rotating drums 11 stop in order. When the three symbols on the winning line 11b corresponding to the bet count of the bet counting display 13a at the time of stoppage are arranged in a specific combination, a number of medals corresponding to the combination are paid out and a big bonus is obtained. Have a special game played.

When the bet button 13 is used to set a bet count and the motor automatic control switch 30 is operated instead of operating the game start switch 14 and the stop switch 15 while the credits are being set, the rotating drum 11 Start rotation automatically. At this time, if the time interval selection switch 31 is set to, for example, 2 seconds, the first rotating drum 11 stops after 2 seconds, and then the remaining 2 rotating drums 11 stop every 2 seconds. At this time, the stop position of the rotary drum 11 changes each time the rotary drum 11 rotates, even if the selected position of the time interval selection switch 31 is the same.

The time interval selection switch 31 can be switched to another time interval on the way, and when the credit runs short or the motor automatic control switch 30 is operated again,
Return to normal operating state.
