2. Description of the Related Art In a conventional typical slot machine, three symbol display windows are formed side by side on a front panel on the front side, and three symbol display windows are formed inside the fuselage so as to correspond to the formation positions of the respective symbol display windows. Reels are arranged. Generally, each reel is formed by attaching a band-like sheet on which the symbols of a plurality of pieces such as numbers and symbols are stuck on an outer peripheral portion of a reel frame, and after starting rotation all at once according to a starting operation of a player, It stops sequentially by each individual stop operation.
On the symbol display window on the front panel, five winning lines are set: upper, middle, lower, rising right, and lower right.
By stopping each reel, 3 reels per reel are displayed on each winning line.
The symbols for the pieces are displayed in an aligned state.

Also, in recent slot machines, prior to the start of a game, a large number of medals are inserted into a medal slot and stored in the body, and a bet button switch provided on the front of the body is pressed. Accordingly, a “credit” method is adopted in which a predetermined number of medals are consumed from the stored medals (hereinafter, referred to as “reserved medals”) and inserted into the game. The credit-type stored medals are held in an electronic data format in the control unit. When the number of stored medals to be inserted in one game is set by operating a bet button switch, the stored medals are stored. While the set number of medals is withdrawn, a predetermined number of winning lines are activated.

Is done. When the starting lever 14 is operated after two consecutive betting operations, two medals are inserted from the stored medals, and a game in which three winning lines L1, L2, and L3 are activated is started. You.
Further, when the start lever 14 is operated after three consecutive betting operations, one medal is inserted from the stored medals, and the game starts in a state where only the central pay line L1 is activated. Become like

As described above, the management of the stored medals is performed by counting the stored medals by the control circuit, and the number of the stored medals is reduced by three by the first betting operation. Then, for the second and third betting operations, the number of stored medals is increased by one in order to return the medal once set as the inserted medal to the stored medal again.

As described above, in response to the betting operation, the medal actually stored does not move, but only the number of stored medals held in the control circuit in the electronic data format is changed. There is no need to provide a processing mechanism, and control associated with the operation of changing the set number of inserted medals can be simplified.

FIG. 4 shows an electrical configuration of the slot machine. In the figure, reference numeral 25 denotes a control circuit comprising a microcomputer, which controls the CPU 26,
R for storing a program and a table for the lottery
It includes an OM 27, a RAM 28 used for reading and writing data, and the like.

Various input / output units are connected to the CPU 26 via a bus 29. The CPU 26 recognizes various input signals based on a program in the ROM 27, and supplies a drive signal to an output unit to play a game. Executes a series of processes related to. The input section includes the start lever 14, the stop button switches 15a, 15b, 15c, the bet button switch 17, the settlement switch 18, the changeover switch 19, and a medal detection for detecting a medal inserted through the medal slot 16. The sensor 30 and the like are connected. The output unit includes a medal payout machine 6, the stepping motor 9
In addition to a reel drive unit 31 for driving the a, 9b, 9c, a stored number display 23, a hit number display 24, an audio circuit 32 for outputting a sound effect and the like are connected.

FIG. 5 shows a game control procedure when a credit-type game is executed in the slot machine. The steps of each procedure in the figure are indicated by “ST”. N indicates the number of inserted medals set by the betting operation, and M indicates the number of stored medals.

When the game mode of the credit system is selected by the changeover switch 19 and a bet operation is performed in a state where a predetermined number of medals are stored, ST1 becomes "YES". In response to this, in the next ST2, the CPU 26 subtracts three medals from the stored medals and sets them as inserted medals, and activates the five winning lines L1 to L5 in the subsequent ST3.

When the starting lever 14 is operated in this state, ST4 becomes "YES" and the process proceeds to ST11 to start the game. On the other hand, if the bet operation is performed again before the start lever 14 is operated, ST4 returns to “N”.
O ", ST5 becomes" YES ", and further proceeds to ST7 via ST6. In ST7, the number of inserted medals N
By counting down and counting up the number M of stored medals, three inserted medals are reduced to two and one deducted medal is returned to the stored medals. Next ST8
Then, out of the five activated pay lines L1 to L5, the oblique lines L4 and L5 are invalidated, so that
Effective winning lines are reduced to three lines.

When the third betting operation is performed,
Similarly, by the process of ST7, one more medal is returned to the stored medal, and only one medal is set. Further, by the process of ST8, the upper and lower horizontal pay lines L2 and L3 are invalidated, and only the central pay line L1 remains valid.

If the fourth bet operation is performed when the number of inserted medals becomes one, ST6 becomes "NO" and the process proceeds to ST9. The number M is returned to the value set in ST2, and the five pay lines L1 to L5 are activated again in ST10. Thereafter, even if the betting operation is continued, the same processing as described above is executed, so that the number N of inserted medals is 3 to 2, 2 to 1, and 1
It is sequentially updated from three to three.

After the player has set the desired number of inserted medals by the predetermined number of betting operations by operating the start lever 14, the process proceeds from ST4 to ST11.
Each of the reels 8a, 8b, 8c starts simultaneously. Thereafter, each time the player presses the stop button switches 15a, 15b, 15c, ST12 becomes "YES" and the next ST1 is executed.
At 3, the corresponding reel stops. Although illustration is omitted in this embodiment, the CPU 26 performs an internal lottery to determine whether or not a winning is established in accordance with the operation of the starting lever 14, and when stopping each reel, the CPU 26 performs the lottery in accordance with the lottery result. A “pull-in control” is executed to pull in and stop symbols as much as possible.

Thus, all the reels 8a, 8b, 8c
Stops, ST14 becomes "YES" and ST15
Proceed to the winning determination of. If a winning symbol combination is established on any of the activated five winning lines L1 to L5, ST16 becomes "YES" and a predetermined number of medals are paid out in ST17.

According to the above procedure, the player can perform the most frequently performed setting operation for inserting three medals by one bet operation, so that the number of bet button switches is reduced to one, and Operation can be simplified. In addition, since the setting operation of two or one inserted medal is realized by repeating the betting operation, any one to three setting operations can be performed without any problem.

The process of reducing the number of inserted medals is not limited to the operation of the bet button switch 17, but may be performed by operating another switch, for example, the settlement switch 18. FIG. 6 shows that in a credit-type game, after the betting operation is activated only once and three inserted medals are set, the number of inserted medals is sequentially reduced by operating the settlement switch 18 (hereinafter, referred to as “adjustment operation”). The control procedure in the case of the above is shown. Here, each procedure is indicated by "st", and the number of inserted medals and the number of stored medals are indicated by N and M as in FIG.

In this embodiment, the inserted medals set by the first bet operation are sequentially reduced by the settlement operation, and the settlement operation is performed when the set number of inserted medals becomes zero, and the accumulated medals are stored. The medals are collectively settled, and medals corresponding to the number of stored medals are paid out to the medal tray 22 from the medal payout exit 21.

First, in the same manner as the procedure of FIG.
Medals are deducted and set as throw-in medals, 5
The winning lines L1 to L5 of the book are activated. Thereafter, when the player performs the settlement operation without operating the starting lever 14,
st4 becomes "NO", st5 becomes "YES", and the CPU
26, the inserted medals are reduced one by one to return to the stored medals, and a predetermined number of winning lines are invalidated (st
7, 8).

Therefore, if the settlement operation is performed once after the bet operation, the number N of inserted medals is reduced to two and the number of effective pay lines is reduced to three. Further, when the second payment operation is performed, the number N of inserted medals is reduced to one, and the number of valid pay lines is reduced to one. When the starting lever 14 is operated in a state where a predetermined number of inserted medals have been set in this way, st4 and 13 are both set to "YES".
Game control is executed in the same procedure as in T11 to ST17.

On the other hand, if the settlement operation is performed three consecutive times after the betting operation, the number N of inserted medals becomes zero and the number M of stored medals returns to the value before the betting operation by the processing of st7. . In addition, by the processing in st8, the central remaining pay line L1 remaining last is also invalidated, and the state returns to the state before the bet operation.

When the player performs the settlement operation again in this state, st5 becomes "YES", st6 becomes "NO", and C
The PU 26 proceeds to st9, discharges M medals from the hopper 6a, and pays out the medals to the medal tray 22 from the medal payout exit 21. In the subsequent st10, the process is terminated after the stored medal number M is cleared to zero.

When the number N of inserted medals is reduced to 0 by the three settlement operations, if the betting operation is performed again, st11 becomes "YES", st12 becomes "NO", and the process returns to st2. Again, three inserted medals are set. If the start lever 14 is operated even when the number N of inserted medals becomes zero, the determination of st13 is “NO”.
As a result, the operation of the starting lever 14 is invalidated.

Note that, in the case where the settlement operation is performed by mistake, a message or other appropriate notification is performed to accept the player's confirmation operation before performing the settlement processing of the stored medals in st9 and st. You may. The confirmation operation in this case is realized by a predetermined switch operation such as a settlement operation again. If a bet operation is performed instead of the confirmation operation, the process returns to st2 by the same determination processing as in st11 and st12. Then, three inserted medals are set again.

In the procedure of FIGS. 5 and 6, the medals subtracted from the inserted medals are returned to the stored medals in response to the betting operation or the settlement operation after the setting of the three inserted medals. The processing relating to medals is not limited to this, and the hopper 6a is driven each time an operation is performed,
The deducted medals may be refunded. Also, the set number of inserted medals after the subtraction processing is two or one.
Only in the case of coins, it may be set so that the direct insertion of medals from the medal insertion slot 16 is accepted and the set value of the inserted medals is returned to the original state.

FIGS. 5 and 6 show the flow of the game under normal control. In this type of slot machine, a special “7” is displayed on the activated pay line. When three winning symbols are arranged, a special winning is achieved, and a special control state called a “bonus game” may be set in which a game in which a winning occurs with a high probability frequently occurs. In this bonus game, generally, only a central winning line L1 is activated by inserting one medal, and a predetermined winning symbol is drawn on this line L1 and stopped.

Therefore, the slot machine 1 of this embodiment
However, if the game shifts to a bonus game due to the formation of a special prize, only the first one bet operation is activated,
It is desirable to perform a special medal setting process for setting one medal as an inserted medal. With this configuration, the player can set the inserted medal for the bonus game by performing only one bet operation as in the case of the normal game, and the operation becomes complicated by changing the control mode. Can be avoided.

Here, the present slot machine in which a maximum of three medals are inserted by a bet operation has been described as an example. However, when four or more inserted medals are set, the same applies to the case where a single medal is set. The configuration can be made so that the setting operation of all inserted medals can be performed by one bet button switch.

In the above embodiment, the set number of inserted medals is changed according to the number of setting operations by the player. However, when the switch is kept pressed for a predetermined time, it is regarded as one operation. It is also possible to change the set number of inserted medals by converting the length of the pressing time into the number of operations.

[0062]

According to the first and third aspects of the present invention, by operating the setting switch once, it is possible to set the n medals from the stored medals as the inserted medals. The setting operation can be easily performed, and a complicated operation for setting the medal can be avoided. Moreover, by continuously operating the setting switch or the settlement switch, the set number of inserted medals is reduced one by one, so that a different number of medals can be inserted by one or two switches, The configuration of the operation unit can be simplified.

According to the second aspect of the present invention, after the set number of inserted medals is reduced to one by operating the setting switch a plurality of times, the set number of inserted medals is reduced to the original n by operating the setting switch again. Since the number of sheets is restored, it is possible to start over if the setting operation is incorrect.

According to the fourth aspect of the present invention, after the settling switch is operated a predetermined number of times and the number of set medals becomes zero, the settling switch is operated again to perform the settling process of the stored medals in the body. Therefore, it is possible to perform the settlement process in the middle of the game operation together with the process of canceling the insertion medal setting process, and it is possible to provide a highly convenient slot machine.

According to the fifth aspect of the present invention, the medals subtracted from the inserted medals by operating the setting switch or the settlement switch are returned to the stored medals, so that the stored medals can be prevented from being lost. On the other hand, according to the invention of claim 6, since the deducted medals are paid out of the body, there is an advantage that it is easy to recognize that the inserted medals have been reduced.

According to the seventh aspect of the present invention, when a medal is directly inserted from outside the machine after the set number of inserted medals is reduced by operating the setting switch or the settlement switch, the medal is accepted and inserted. Is returned to the value before the reduction processing, so that the medal setting processing can be restarted in the middle as in the second aspect of the invention.

According to the eighth aspect of the present invention, when a special control state different from the normal state is entered due to establishment of a special prize or the like, the setting operation by the setting switch is made effective only once, and a certain number of sheets (for example, Since one (1) medal insertion is set, even if the set number of medals changes between the normal game and the special game, it is possible to cope with the same setting operation.

According to the ninth aspect of the present invention, since the stored medals are held in the electronic data format, there is no need to manage the actual medals in the machine as the stored medals, and the configuration and control of the medal storing section can be simplified.

In the tenth aspect, the setting switch is set to 1
By performing this operation, the medals of the maximum number of inserted medals can be set as the inserted medals from the stored medals, so that the most frequent setting operation can be performed easily, and the setting operation is repeated thereafter. Thereby, all the medal shooting operations can be executed without any problem.
