Means that the continuous opening and closing operation of the variable prize device (40) is repeatedly executed with a predetermined maximum continuous number as an upper limit.

When the ball has won the starting winning opening (21, 22), the main control unit (400) executes a lottery, displays the result of the lottery on the lottery display unit (60), and displays the result of the lottery. In response to changing the open state of the variable prize device (40) or the time of the open state to open and close the variable prize device (40), the open state and the open state of the variable prize device (40) are changed. It is possible to prevent the game from becoming monotonous without the time being constant.

When the game condition change detecting section (30) detects the passage of the ball, the main control section (400) re-executes the lottery after the opening and closing operation of the variable winning device (40), and the lottery is executed. The result is displayed on the lottery display section, and the opening or closing time of the variable prize device (40) is changed according to the result of the lottery to open and close the variable prize device (40). Depending on the result of the lottery, there is a possibility that the state advantageous to the player may be continued, and the player may perform the lottery such that the open state of the variable winning device (40) or the time of the open state is further advantageous to the player. Will be expected for the result.

If the game condition change detection unit (30) detects the passage of the ball during the opening / closing operation of the variable winning device (40), the right to re-lottery may be reserved.

When a ball is won in the variable winning device (40), and when the number of winning balls is within a predetermined maximum number,
A predetermined number of prize balls are awarded per winning ball, and when the number of winning balls exceeds the maximum number, a predetermined number of prize balls or less are awarded per winning ball, and the predetermined number is randomly selected. With the result of the lottery, the pattern of the number of prize balls to be awarded varies greatly depending on the result of the lottery, and the player becomes more interested in the result of the lottery. Can be enhanced.

When a predetermined lottery result is displayed on the lottery display unit and at least one of the balls that have won the variable prize device (40) wins in the specific area (44), the lottery is executed again. You may do so. According to the result of the re-lottery, the open state and the time of the open state of the variable winning device (40) are changed again.

For example, the variable winning device (40) has a pair of movable pieces (41) rotatably supported on each other, and the movable pieces (41) are opened and closed to open and close. When each movable piece (41) is opened and opened, the ball flowing down on the game board (11) is picked up by each movable piece (41). The ball can be guided to the variable winning device (40) with the winning probability.

Here, the closing condition is established, for example, when a predetermined number of balls (10 or the like) wins after opening the variable winning device (40), or when a predetermined time elapses.

During the initial opening / closing operation of the variable winning device (40), the firing control means (422) changes the upper limit value of the number of firing balls per unit time to a value higher than usual. This increases the probability that the ball wins in the specific area (44) during the initial opening / closing operation, and thus increases the probability of the continuous opening / closing operation occurring, thereby increasing the profit of the player.

[0033] Also, during the continuous opening and closing operation of the variable winning device (40) by the firing control means (422),
If the upper limit value of the number of firing balls per unit time is changed to a value higher than usual, the possibility that such a continuous opening / closing operation is repeated up to the maximum number of times is naturally increased, thereby increasing the profit of the player. Becomes possible.

Further, the launch control means (422) controls the upper limit of the number of shot balls per unit time during the initial opening / closing operation of the variable winning device (40) and the continuous opening / closing operation of the variable winning device (40). If the upper limit value of the number of shot balls per unit time in the medium is set to different values from each other, it is possible to enhance interest in ball shot.

If the upper limit of the number of shot balls per unit time within a predetermined time is limited to within a predetermined regulation value by the launch control means (422), such a regulation value is set to the maximum value of the current laws and regulations. By adjusting to the number of launch balls, it can be considered that business in the interpretation of this law is also possible.

As the ball launching device (800) capable of coping with the gaming machine (10) as described above, the electromagnet portions (801, 80) in which magnetic poles of different polarities are opposed to each other at a predetermined interval.
2) and a launch path (803) provided between the magnetic poles
And a ball supply device (80) for supplying a ball to a standby position (803a) at one end of a firing path (803), and a driving circuit (804) for driving an electromagnet. You may. In this device, when a ball launch instruction is received, power is supplied to the electromagnet until the ball at the standby position (803a) reaches the approximate center between the magnetic poles, and then the power supply is cut off. As a result, the ball at the standby position (803a) is vigorously attracted to the substantially central position between the magnetic poles by the magnetic force, and thereafter released from the magnetic force and vigorously launched onto the game board (11).

By using the sphere launching device (800) having such a configuration, the upper limit number of spheres launched per unit time can be easily adjusted by adjusting the cycle of outputting the launch instruction to the drive circuit (804). Can be changed. Since the ball is fired by magnetic force, the number of balls that can be fired per unit time is large and the ball is excellent in quietness.

In the case where the distance between the magnetic poles is narrow on the side of the standby position (803a), and is tapered in the vicinity of the tip of the magnetic pole so as to increase as the distance from the standby position (803a) increases, the position where the magnetic flux density is highest becomes the standby position. Position (803a)
Since the distance is closer, the distance between the portion having the highest magnetic flux density and the standby position (803a) can be shortened, and the energization time to the electromagnet is shortened. As a result, the maximum number of firings per unit time can be increased.

If the ball is energized so as to generate a gradually attenuating alternating magnetic field instead of shutting off the current after the ball reaches the center between the magnetic poles, the ball can be demagnetized at the time of firing.

As the ball launching device (70), a hammer member (7)
5) A rotary solenoid (71) for driving, and a pulse oscillator (72) for outputting a pulse signal of a predetermined frequency.

, The gaming machine 10 and the game ball lending device 701 are connected. Table controller 700, the corresponding gaming machine 1
It detects, monitors, and controls various operations such as 0 and transmission and reception of signals.

Various information is directly input to the stand controller 700 from the external information output terminal A 435 (see FIG. 1) of the gaming machine 10. Each controller 700 is HALL

Next, the operation of the gaming machine 10 will be described. In FIG. 4, the player rotates the handle 12 so that
The game is played by launching a ball on the game board 11 by the ball launching device 70. In the sphere launching device 70 shown in FIG.
Supplies power to the rotary solenoid 71 that drives the hammer member 75 intermittently for a certain period of time in accordance with the pulse widths a to c of the pulse signal during the predetermined period T. Then, as shown in FIGS. 8 and 9, a magnetic circuit α is formed, and a magnetomotive force is generated.

As a result, the rotor 71c and the shaft 71d
As shown in FIG. 10, a torque F is applied by the magnetomotive force of the coil 71b to rotate in the direction of a stable point D ₀ (minimum magnetic resistance), and stops at a position balanced with the load. Subsequently, when the coil 71b current is eliminated, the holder 75a by the urging force of the spring 75f is returned to the starting position _{A 0,} hammer member 75 come up sphere.

Here, the frequency adjuster 72a arbitrarily adjusts the predetermined period T of the pulse signal output from the pulse oscillator 72, thereby arbitrarily setting the number of shot spheres at which the hammer member 75 hits a ball per minute. be able to. At the time of a normal game, a normal drive signal is output to the frequency adjuster 72a of the ball firing device 70 under the control of the firing control means 422 in the main control unit 400, and the period T of the pulse signal output from the pulse oscillator 72 is set. The period is set to a period T1 (see FIG. 11) whose length corresponds to the number of shooting balls of 100 pieces per minute.

Further, the operation of the hammer member 75 by the rotary solenoid 71 is performed electrically without using a gear mechanism or the like, so that the controllability is good, and accordingly, the firing per unit time is performed according to the game state. The number of balls can be adjusted accurately and easily. In addition, there is no noise of gears or the like meshing, and the sense of quality can be enhanced quietly.

Further, the emission intensity (speed) of the ball can be arbitrarily adjusted easily and easily electrically by the current adjuster 74 for adjusting the output of the output amplifier 73. That is, when the player grips the handle 12 or rotates it by a certain angle or more, the power switch 74a is turned on to turn on the power, and the ball is periodically launched with a firing intensity (speed) according to the rotation angle of the handle 12. It is.

Further, the pulse width adjuster 72b
Since the pulse width of the pulse signal output from the pulse oscillator 72 in a predetermined cycle can be arbitrarily adjusted, when operating at a certain frequency, the ratio of the current energizing time to the current non-energizing time in one cycle can be set arbitrarily. Can be adjusted. Thereby, it is possible to produce a light hitting method (the operation time until the ball is fired) and a heavy hitting method (the operation time until the ball is fired) in the operation of the handle 12.

For example, when 100 balls are fired per minute, the energization time of the rotary solenoid 71 is digitally set to 1: 9, 2: 8, 3: 7, ..., 8: 2, 9: 1. From a theoretical point of view, in the case of 1: 9, the ball is hit very lightly, and in the case of 9: 1, the ball is hit very heavy.

Is performed (S104). Subsequently, the pair of movable pieces 41, 41 of the variable winning device 40 is opened from the closed state once returned to the opened state again (S10).
5).

At this time, the continuous opening / closing operation executing means 421 determines whether at least one ball has won in the specific area 44 of the variable winning device 40 based on a signal from the specific area winning ball detection switch 432. (S10

107).

It is also determined whether or not a predetermined number of ten balls have been won in the entire winning area 43 of the variable winning device 40 while the variable winning device 40 is open (S108). Here, when there are 10 winnings (S1
08: Y), the solenoid 434 is driven based on a command from the continuous opening / closing operation execution means 421, and the pair of movable pieces 41,
41 is closed (S110).

If no winning of 10 balls is made (S108: N), it is determined whether or not a timeout of 10 seconds has occurred (S109). Here, in the case of timeout (S109: Y), the variable winning device 40 is closed (S109).
110). If it is not time-out (S10
9: N), the process returns to the determination of whether or not ten winnings have been made (S108).

If the continuation flag is set at the time when the variable winning device 40 is closed (S111: Y), that is, if the ball has won the specific area 44 when the variable winning device 40 was opened last time, the continuation is continued. By the opening / closing operation execution means 421, the continuous opening / closing operation of the variable prize device 40 is repeatedly executed with the maximum continuous number of times being 16 times as an upper limit (S112, S113).

Next, the lottery execution process of the lottery execution means 424 will be described with reference to the flowchart shown in FIG.

The lottery executing means 424 determines whether to execute the lottery or re-execute the lottery (step S2801). If the lottery is executed or the lottery is re-executed (step S28)
01: Y), the lottery is executed, and the result of the lottery is displayed on the lottery display section 6
0 is displayed (step S2802).

If the result of the lottery is the number “7” (step S2803: Y), the opening angle of the movable piece 41 is set to a large value, or the open state of the movable piece 41 is set to 2.0 seconds. (Step S2804).

On the other hand, if the result of the lottery is not the number “7” and the result of the lottery is the number “3” (step S2803:
N, 2806: Y), the opening angle of the movable piece 41 is set to medium, or the open state of the movable piece 41 is set to 1.2 seconds (step S2807).

Further, if the result of the lottery is not the numbers "7" and "3" (step S2803: N, 280)
6: N), whether the opening angle of the movable piece 41 is set to be small,
Alternatively, the open state of the movable piece 41 is set to 0.8 seconds (step S2808).

Next, after the end of the opening / closing operation (initial opening / closing operation or continuous opening / closing operation) of the variable winning device 40, if the game condition change detecting section 30 detects the passage of a ball (step S2).
805: Y), and returns to step S2801 to determine whether the lottery executing means 424 executes the lottery again.

The flowchart shown in FIG. 22 shows the control of the launch of the ball by the launch device 70 by the launch control means 422. During a normal game, a normal drive signal is output to the frequency adjuster 72a of the ball firing device 70 under the control of the firing control means 422 in the main control unit 400, and the period T of the pulse signal output from the pulse oscillator 72 A first cycle T1 whose length corresponds to the number of launch balls of 100 pieces per minute (FIG. 11)
(See S121).

When the initial opening / closing operation of the variable prize device 40 is started (S122: Y), the firing control means 42 at that time based on the signal from the initial opening / closing operation executing means 420.
2 outputs the number-of-launched-balls increase signal 1 to the frequency adjuster 72a of the sphere launching device 70. Then, the pulse oscillator 72
Is automatically changed to a second period T2 (see FIG. 11) corresponding to the number of shooting spheres of about 200 per minute (S123).

As a result, the probability that the ball will win in the specific area 44 during the initial opening / closing operation increases, so that the probability that the continuous opening / closing operation will subsequently occur increases, and the profit of the player can be increased.

Here, for example, only during the initial opening / closing operation of the variable winning device 40 based on the winning of the ball into the second starting winning opening 22 of the starting winning openings 21 and 22, the unit time is set. The upper limit of the number of shot balls per hit may be changed to a value higher than usual.

If the operation has not shifted to the continuous opening / closing operation following the initial opening / closing operation (S124: N), at that time the firing control means 422 increases the number of spheres fired by the sphere firing device 70 to a normal value of 100 per minute. The control for returning to the number of pieces is executed.
1).

On the other hand, in the case of shifting to the continuous opening / closing operation after the initial opening / closing operation (S124: Y), at the start of the first continuous opening / closing operation, the firing control means 422 operates the frequency adjuster of the ball firing device 70. A different number-of-launched-balls signal 2 is output to 72a, and the length of the cycle T of the pulse signal output from the pulse oscillator 72 is set to a cycle (not shown) corresponding to the number of launched spheres of 150 per minute. It is changed (S125).

As a result, even during the continuous opening / closing operation of the variable winning device 40, the upper limit value of the number of shot balls per unit time is changed to a value higher than usual, and such a continuous opening / closing operation becomes the maximum. Naturally, the possibility of repetition up to the continuation number is also increased, so that the profit of the player can be increased.

As in the present embodiment, the upper limit value of the number of shot balls per unit time during the initial opening / closing operation and the upper limit value of the number of shot balls per unit time during the continuous opening / closing operation are different from each other. By setting the values to different values, it is possible to enhance interest in ball launching. It should be noted that even when the number of spheres fired by the ball launching device 70 increases, the sphere launching device 70 shown in FIG.
Can be quickly and accurately supplied one by one to the launching ball standby position at.

When the continuous opening / closing operation is completed (S1
26: Y), the launch control means 422 executes control for returning the number of launch balls by the ball launch device 70 to the normal number of launch balls of 100 per minute (S121). Further, if the upper limit of the number of fired balls per unit time is limited within a predetermined regulation value within a predetermined time by the launch control means 422, the regulation value is adjusted to the maximum number of fired balls in the current law and regulation. Therefore, it can be considered that business in the interpretation of this regulation is also possible.

Next, the payout operation of the prize ball by the ball payout device 600 will be specifically described. First, in the stopped state where the main solenoid 650 and the sub solenoid 660 are not driven, as shown in FIG.
The main stopper 630 is in a state of being engaged with the ratchet wheel 620 by the urging force of 32, whereby the sprocket 610 is kept stopped and the ball is not ejected.

When the payout of N balls is instructed by the prize ball management means 423 of the game control CPU 411, the payout circuit 437 controls the ball payout device 600 as shown in FIG. That is, first, the number of shot balls fired by the ball shooting device 70 for one minute is determined (S2110). Here, when the number of launched balls is 100 or less per minute (S2111: Y), only one of the two ball payout units 601 of the ball payout device 600 is set to the active state (S2112). . On the other hand, the number of shot balls is 200 per minute.
If the number is (S2111: N), the ball payout device 600
Are set to the operating state (S2113).

Next, the ball payout unit 601 in the operating state
Main solenoid 650 and sub solenoid 660
Is driven (S2114). However, if the number of payouts is equal to or less than the predetermined amount, one of the ball payout units 601 from the beginning.
Only the main solenoid 650 is started.

When the main solenoid 650 and the like are driven, the main stopper 630 also moves to the sub-stopper 640.
Is held off the ratchet wheel 620 as shown in FIG. Accordingly, the sprocket 610 continuously rotates at a high speed due to the weight of the ball, and the balls are successively discharged at a high speed.

During the high-speed payout, the prize ball managing means 423 receives the signal of the detection sensor 683 output each time a ball is paid out one by one, counts the number of payouts H, and further calculates this as the command value. N minus this difference N-
It is determined whether or not H has become a minute value (preferably about 4 to 8) (S2115). Here, when the two ball payout units 601 are operating, the number of payouts paid out by each ball payout unit 601 is, of course, summed and calculated as the number of payouts H.

When the difference between the payout number H and the command value N becomes a very small value (S2115: Y), the two ball payout units 60
1 is activated, one of the sub-solenoids is stopped first, then the remaining one sub-solenoid 660 is turned off, and a periodic pulse signal is sent only to the main solenoid 650. Main solenoid 6 until they match
Only 50 is operated intermittently (S2116).

Then, the main stopper 630 and the sub-stopper 640 are alternately engaged with the sprocket 610, so that the sub-stopper 640 is engaged.
Each time the main stopper 630 is disengaged from the sprocket 610, the main stopper 630 allows the sprocket 610 to rotate corresponding to half of the recess 610a and engages with the sprocket 610. From the same relationship, when the sub-stopper 640 is disengaged from the sprocket 610, the concave portion 610
The main stopper 630 engages with the sprocket 610 by allowing the rotation of the sprocket 610 corresponding to half a.

Therefore, each time the intermittent operation is performed for one cycle, the sprocket 610 is consequently one recess 610a.
As a result, one ball is ejected every time the intermittent operation is performed for one cycle. When the number of payouts matches the command value (S2117: Y), the prize ball management unit 423
Returns the main solenoid 650 to the stopped state via the payout circuit 437 (S2118).

As described above, according to the ball dispensing apparatus 600, the sprocket 610 is continuously rotated according to the weight of the ball to continuously discharge the ball until the number of dispensed approaches the command value. When the number approaches the command value, the sprocket 6
Since the rotation of 10 is switched to intermittent rotation and balls are paid out one by one, there is no possibility of delaying the stop of the rotation of the sprocket 610 and paying out extra balls. Can be put out.

Most of the balls are sprockets 610
Since the paper is discharged at the high rotation speed, the payout speed can be increased as a whole. Moreover, the ball payout unit 601
Are provided, it is possible to sufficiently cope with an increase in the number of shot balls per unit time by the ball shooting device 70.

Also, the ball hit on the game board 11 is
After being collected in the ball collecting case 8, FIG.
Is introduced into the intake stage 91 of the ball discharge device 90 shown in FIG.
Each of the plurality of alignment rails 93 is sent to the end side in a state of being aligned in a line. When the balls flow into each of the alignment rails 93 in a multi-stage manner, the balls in the second and higher layers contact the rocking body 96 and are prevented from proceeding. At this time, even if the advancement of the ball in the upper layer is prevented, the ball in the upper layer can move slightly due to the swing of the rocking body 96, so that the movement of the ball in the lower layer (first stage) is not hindered. Instead, the ball is smoothly advanced to the end.

The sphere has a plurality of detection sensors 94 provided corresponding to the end of each alignment rail 93.
, A plurality is counted at a time. Since a large number of balls can be counted in a short time by the plurality of detection sensors 94 in this way, even if a large number of balls are hit on the game board 11 in accordance with the increase in the number of shot balls by the ball shooting device 70, a prize is won. The player can play the game smoothly without hindering the counting of balls and out-balls. The counted balls are discharged through the payout stage 95 to the collecting gutter in the gaming machine island.

Note that the gaming machine according to the present invention is not limited to the above-described embodiment. For example, the upper limit of the number of shooting balls per unit time during occurrence of a special prize is 15
The number is not limited to 0 and 200, and may be set to another numerical value. Further, when the continuous opening / closing operation is performed, the upper limit of the number of shot balls may be set to the normal value without changing the upper limit value.

As another embodiment, a case where the variable winning device 40 is in the initial opening / closing operation based on the winning of a ball into the predetermined second starting winning port 22 of the starting winning ports 21 and 22 is described. May be set so that the upper limit value of the number of shot balls per unit time is changed to a value higher than usual.

Further, in the ball launching device shown in FIG. 25, a Zener diode is connected in parallel to both ends of a variable resistor, and a Zener voltage Vz generated in the Zener diode is divided by the variable resistor, and is proportional to the divided voltage Vd. The charging voltage is
The voltage is generated at both ends of an electrolytic capacitor (not shown) of the drive circuit, and a divided voltage Vd corresponding to the operation amount of the firing dial is generated at the movable contact of the variable resistor.

When a ball is detected, a discharge current is supplied from the electrolytic capacitor to the exciting coil, and a movable yoke (not shown) operates to strike the ball by the magnetic force generated in the exciting coil. That is, since the charging voltage according to the operation amount of the firing dial is applied to the excitation coil, the ball can be launched at a firing speed according to the operation amount of the firing dial.

Further, a configuration may be adopted in which a resistor having an allowable error smaller than the allowable error is connected in parallel to the variable resistor. This reduces the variation between the manipulated variable and the voltage generated on the variable resistor, and reduces the variation between the manipulated variable and the ball's firing speed and flight distance.

Further, a new variable resistor is connected between each movable contact of the variable resistor and the resistor having the small tolerance, and the ball is moved based on the firing voltage generated at the movable contact of the new variable resistor. You may make it fire. As a result, the voltage generated at the movable contact of each resistor can be finely adjusted to further reduce the variation between the operation amount and the launch speed and flight distance of the ball.

As shown in FIG. 26, when the ball that has entered below the rocking member pushes up the rocking member, the rocking member is displaced from the restrained position to the release position. When the hook of the swinging member is disengaged from the striking rod, the striking rod is retracted by the urging force of the return spring, and then the striking rod is driven forward, so that the entering ball can be struck. That is, if the ball has not entered below the swinging member, the striking rod does not recede, thereby preventing the occurrence of air strike.

Further, as shown in FIG. 27, the ball launching device may be of an electromagnetic type. This ball launching device 800
A yoke 801 having different magnetic poles opposed to each other at a slightly wider interval than the diameter of the sphere, a coil 802 wound around the yoke 801, and a launch path 803 provided to penetrate between the magnetic poles of the yoke 801. And a drive pulse generating circuit 804 for supplying a pulse-like current to the coil 802. One end of the firing path 803 is at a shooting ball standby position 803a, and balls are successively supplied from the above-described ball supply device.

When the ball is fired, the shooting ball standby position 80
The coil 802 is energized until the ball located at 3a reaches the opposing magnetic pole position 803b, and the sphere just moves to the magnetic pole position 8
When reaching 03b, energization is stopped. The ball at the firing ball standby position 803a is attracted by the magnetic force generated by the start of energization of the coil 802, and vigorously violates the magnetic pole position 80.
By moving to the side of 3b and arriving at the position 803b between the magnetic poles, the energization is stopped, so that it is fired onto the gaming surface 11 through the guide rail 11a with the same momentum.

In the normal firing mode, the driving pulse 810
Is a maximum of 10 per second as shown by a waveform 820 in the figure.
0 pulse is output, and in the high-speed firing mode, the waveform 82
As shown in FIG. 1, the pulse interval becomes approximately half, and a maximum of 200 pulses are output per second.

By using such an electromagnetic ball launching device 800, the upper limit number of balls launched per unit time can be easily changed only by adjusting the pulse period, and the ball is launched by magnetic force. Therefore, it is possible to further increase the quiet and upper limit of the number of firings per unit time. Also, the distance between the magnetic poles is narrower on the side of the firing standby position 803a, and is tapered near the tip of the magnetic pole so as to increase as the distance from the firing standby position 803a increases. become.
That is, the distance between the point where the magnetic flux density is highest between the magnetic poles and the emission standby position 803a is shortened, and the energization time to the coil 802 is shortened. As a result, the maximum number of firings per unit time can be further increased.

The above-described current regulator 74 turns on / off the power supply with the power switch 74a and adjusts the output of the output amplifier 73. Current regulator 7
The volume 4 (variable resistance machine) is provided integrally with a handle 12 provided on the game board 11 side. Handle 12
The power switch 74a is turned on by the operation described above, and the firing intensity (speed) of the hit ball can be freely adjusted by the amount of rotation of the handle 12.

That is, when the rotation angle of the handle 12 is small, the output of the output amplifier 73 is small, and the launching strength of the hit ball is small. On the other hand, handle 1
When the rotation angle of 2 is large, the output of the output amplifier 73 increases, and the launching strength of the hit ball increases. In addition,
By providing means for applying a frictional force between a side surface of the handle 12 distant from the rotation axis of the handle 12 and a side surface of the main body of the gaming machine 10 on which the handle 12 is supported, the handle 12 can be rotated freely. You may comprise so that it can be fixed at a position. Needless to say, the holding state of the handle 12 due to the frictional force can be easily released by a predetermined operation of the player.
