The variable prize ball device 20 and the electric accessory 6 provided on the game board 1 are controlled by a game control circuit comprising a microcomputer 60 shown in FIG.
FIG. 4 is a circuit diagram showing the game control circuit in a block configuration. In the figure, the game control circuit includes a microcomputer 60 as a control center. The microcomputer 60 includes an MPU 61 capable of executing a control operation in a predetermined procedure, a ROM 62 storing operation program data of the MPU 61, , A RAM 63 capable of writing and reading necessary data, and an input / output circuit 64. The input / output circuit 64 is connected with a start winning ball detection switch 8, an electric accessory switch 5a, 5b, a specific winning ball detection switch 50, and a winning ball detection switch 51 via a switch circuit 65, and a solenoid circuit 66.
The ball receiving member solenoids 28a and 28b, the arm solenoids 32a and 32b, the body solenoid 39, the eyeglass solenoid 36, and the electric accessory solenoid 7 are connected to each other through the The LED 44, the decoration LED-A, and the decoration LED-B are connected, and the game effect lamp 18,
Windmill lamps 12a and 12b, rail decoration lamps 17, side lamps 15a and 15b, shoulder lamps 13a and 13b,
Sleeve lamps 14a and 14b and accessory lamps 54a and 54b are connected. Although not shown, a speaker is also connected via a sound circuit. Further, various voltages are supplied from the power supply circuit to the above-described game control circuit.

An example of a specific operation of the game control circuit described above will be described with reference to timing charts and explanatory diagrams shown in FIGS. FIG. 5 shows a state in which one of the operating ports 4a and 4b for the electric accessory is won and the electric accessory switch 5 is activated.
This shows the operating state of the electric accessory solenoid 7 when one of the a and 5b is turned ON. Then, one of the electric accessory switches 5a and 5b is turned on and the start signal S1
Is derived, the electric accessory solenoid 7 performs the ON state for the time t1 (for example, 0.600 seconds) twice with an interval of time t2 (for example, 1.000 seconds). Therefore, the opening / closing wing piece of the electric accessory 6 is opened twice.

FIG. 6 shows an operation when a hit ball is received by the electric accessory 6 (start winning) when the electric accessory 6 is opened twice by the above operation. In the figure, a hit ball wins the electric accessory 6 and the start winning ball detection switch 8 is turned on.
Then, the start signal S2 is derived. After the start signal S2 is derived, first, at time t6 (for example, 1.000
Seconds), the ball receiving member solenoids 28a, 28b
Changes the ON state for a time t7 (for example, 0.512 seconds) to a time t8.
It is performed twice at intervals of time (for example, 0.500 seconds). Therefore, the ball receiving members 27a and 27b open and close twice. The opening and closing operations of the distribution members 31a and 31b are performed in conjunction with the opening and closing operations of the ball receiving members 27a and 27b. That is, after the start signal S2 is derived, when the arm solenoids 32a and 32b elapse the time t3 (for example, 1.256 seconds), which is a time longer than the time t6, the time t
The ON state for 4 hours (for example, 0.256 seconds) is performed twice at intervals of t5 time (for example, 0.756 seconds). Therefore, the movement of the distribution members 31a and 31b in the horizontal direction is two times.
Times. In this case, the distribution member 31
The start of the movement of the a and 31b starts slightly later than the start of the opening of the ball receiving members 27a and 27b, and the end of the movement is performed simultaneously with the completion of the opening of the ball receiving members 27a and 27b.

In FIG. 6, the ball receiving members 27a, 27
During the time t9 until the two opening / closing operations of the ball 7b are completed, even if the next hit ball turns on the start winning ball detection switch 8, the ON is invalidated, and the ball receiving members 27a, 27b are processed twice. After the opening / closing operation is completed, a predetermined time t10 (for example,
Until the elapse of 3.000 seconds), the effective operation time of the specific winning ball detection switch 50 is set in consideration of a margin until the winning ball turns on the specific winning ball detecting switch 50.

The ball receiving member 27 based on the winning start described above.
FIG. 7 shows the opening / closing cycle operation in the case where the winning prize ball received during the opening / closing operation of a and 27b wins the specific winning opening 47, that is, in the big hit game state. In the figure, when a winning prize ball received by the variable prize ball device 20 at the time of starting prize winning or opening / closing cycle is guided to the specific prize opening 47 and the specific prize ball detecting switch 50 is turned on, the continuation signal Rn
(1 ≦ n ≦ 15) is derived. Even if the continuation signal Rn is derived, the ball receiving members 27a and 27b are not immediately opened and closed, but until the opening and closing operation is started, first,
The fuselage solenoid 39 is operated for t13 hours (for example, 0.30 hours).
0 second) and the time t14 (for example, 0.300)
After repeating the OFF state for a second) a plurality of times (three times in the illustrated example), the state changes to the ON state. Therefore, when viewed from the front of the game board 1, the horizontal body portion 38 is viewed, and the stationary projection 40 has entered the communication opening.

After the derivation of the continuation signal Rn, when the time t11 (for example, 2.4 seconds) elapses before the opening / closing operation starts, the eyeglass solenoid 36 is turned on. As a result, the spectacle member 34 rises and becomes invisible,
The cloak member 35 is opened. Note that the eyeglass solenoid 36 is turned on at time t12 (for example, 0.600 seconds) before the opening / closing operation of the ball receiving members 27a and 27b is started.
Thus, before the time t15 (for example, 0.900 seconds), the body solenoid 39 is turned on continuously. Therefore, since the form of the character looks completely different to the player, the game state can be known by the change of the character. In the present embodiment, when the character changes to a state of flying in the sky with glasses, it is possible to know that the opening / closing cycle will be started soon and that the winning ball can be stopped.

Thus, after the continuation signal Rn is derived,
When the time t16 (for example, 3.000 seconds) has elapsed, the ball receiving member solenoids 28a and 28b and the arm solenoids 32a and 32b perform opening and closing operations in synchronization. In this case, the ON time and OFF time of each solenoid are
They are t17 and t18, respectively. However, OF
The time t18, which is the time F, is set so as to be variable according to the number of continuations of the open / close cycle, as described below. When the number of winning balls received during the opening / closing operation of the ball receiving members 27a and 27b becomes six, or when the sixteen opening / closing operations are completed before winning six, the eyeglass solenoid 36 and the body Solenoid 39 for OF
F. For this reason, the character also returns to the original state, and the stationary projection 40 also retreats, so that the winning ball suspended in the communication opening flows down the lower passage 41b. In this case, since the lower passage 41b mainly faces the specific winning opening 47, there is a high possibility that the lower right passage 41b will be guided to the specific winning opening 47 and the continuation right will be established. FIG. 7 shows a timing chart in a case where the winning ball received during the opening / closing operation of the ball receiving members 27a and 27b is not guided to the specific winning opening 47, and the specific winning opening 47 is won on the way. In this case, the driving of all the solenoids is stopped, and the same operation as that immediately after the continuation signal Rn is derived is started. Also, when the 18 opening / closing cycles have been completed, the effective operation time t10 of the specific winning ball detection switch 50 is measured in the same manner as described above.

In this embodiment, as described above, the time t18, which is the closing time of the open / close cycle, can be changed according to the number of continuations. FIG. 8 shows four types of opening / closing cycle patterns having different t18 times.
The opening / closing cycle of t17 = t18 (0.8 s) is shown, and the pattern B is t17 (0.6 s) ≦ t18 (0.8 s)
The pattern C shows t17 (0.4
s) ≦ t18 (0.8 s), and an opening / closing cycle of t17 (0.2 s) ≦ t18 (0.8 s).

The four types of opening / closing cycle patterns shown above are arbitrarily selected and set by the method shown in FIG. That is, in FIG.
When the specific winning ball detection switch 50 is turned on (hereinafter referred to as V winning) from among the random numbers in which the numerical values 0 to 3 are updated, one value is extracted. Then, when the extracted value is “0”, the pattern A is set, and the opening / closing cycle based on the V winning is the pattern A
Will be executed. Similarly, when the value extracted at the time of the V winning is "1", the pattern B is set, and the opening / closing cycle based on the V winning is executed in the pattern B, and the value extracted at the time of the V winning is " 2 ", the pattern C is set, and the opening / closing cycle based on the V prize is
When the value extracted at the time of the V winning is "3", the pattern D is set. The opening / closing cycle based on the V winning is executed by the pattern D. The numerical value extracted at that time is displayed on the opening / closing pattern display LED 26.

As described above, in the present embodiment, in the opening / closing cycle in which the variable winning prize device 20 repeats the first state and the second state, the continuation right is established during the second state. Since one of the four types of opening / closing patterns A to D is selected and set for each opening / closing operation pattern, it is possible to change the opening / closing operation pattern for each opening / closing cycle, thereby attracting the interest of the player. Further, since the time in the first state is not changed, the winning rate at which the hit ball wins the variable winning ball device 20 by each opening / closing cycle does not decrease, and the player is not disadvantaged. In particular, since the closing time of the opening / closing patterns BD is shorter than the closing time of the opening / closing pattern A which is a standard opening / closing pattern, the time of one entire opening / closing cycle is shortened. Since the number of hit balls fired by the player decreases, there is an advantage that the payout rate increases as a result through the big hit game state.

In the above-described embodiment, the opening / closing patterns in all the opening / closing patterns have the same closing time. However, as shown in FIG. Any of H may be selected and set. Also in this case, a change can be given to the opening / closing operation pattern for each opening / closing cycle, which can attract the interest of the player. Further, since there is no change in the time in the first state, the winning rate at which the ball hits the variable prize ball device 20 by each opening / closing cycle does not decrease, and not only does it not become disadvantageous to the player. , One of the opening and closing patterns E to H
Since the time of the entire opening / closing cycle is shortened, the number of hit balls shot by the player during that time is reduced, and the advantage that the payout rate is eventually increased through the big hit game state can be exhibited.

Further, in the embodiment shown in FIGS. 8 and 10,
One of four predetermined opening / closing patterns is V
The selection and setting for each prize are shown. However, four or more or less than four types may be used as long as the number of continuations is predetermined. You may make it select and carry out in order or at random. Further, in the above-described embodiment, the opening and closing pattern in which the closing time is predetermined is prepared.
Every time the opening operation is completed, the closing time may be randomly selected from a plurality of prepared closing times and set.

In the above-described embodiment, the ball receiving members 27a and 27b of the variable winning ball device 20 that open and close are shown.
