Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a launching device capable of launching one ball to a game section of a game board provided with an electric gaming device, and a launch control of the launching device. And a game control means for controlling the electric game machine.

<Related Art> A launching device in a ball game machine requires a stable firing operation for playing a ball game, and various driving sources have been proposed.

For example, in a launching device using a synchronous motor as a drive source, the number of launches per unit time is mechanically fixed by a rotational speed of the synchronous motor with respect to a frequency of a power supply and a gear ratio of a reduction gear. In a launching device using a pulse motor, a rotary solenoid, or the like as a drive source, the number of balls that can be fired per unit time is fixed by adjusting the pulse interval of a drive pulse supplied to the drive source. Is configured.

<Problems to be Solved by the Invention> However, in a game using a ball-and-ball game machine, it is not always effective to fire a ball at a constant cycle, and the game is performed by changing the number of fired balls according to a game mode. In some cases, it is possible to increase profits or reduce disadvantages.

For example, in a game mode such as a state in which the variable prize device is open, by increasing the number of balls to be fired per unit time, the possibility that the ball will win in the open variable prize device is increased, and the normal state is established. It is possible to obtain more game profits.

In addition, a predetermined upper limit number is provided in the prize memory in the start winning prize port to which a variable display start condition of the variable display device can be provided, and a variable display start condition is provided for a start prize of more than this upper limit number. Because only the game profit as a prize ball is given without performing, in the state where the number of starting memories is large,
If the number of firing balls per unit time is large, there is a possibility that a start winning prize exceeding the upper limit number of the winning memory may occur, and in such a case, it is better to suppress the number of firing balls per unit time. It is.

Note that a skilled player may stop the firing operation when such a game mode occurs, and perform a game so that the start winning is not wasted as a start condition of the variable display, and depending on the skill of the player, The disadvantage could increase or decrease.

<Means for Solving the Problems> In order to solve the above problems, the invention according to claim 1 includes:

The invention according to claim 2 is the game device according to claim 1, wherein the game control means is configured to be able to generate a special game state in which the electric game device is advantageously controlled by a player, and the firing number change control means is provided. Calculates the number of launch balls per unit time based on the special game state signal as the game mode signal output from the game control means, as the first number of launch balls as a normal number of launch balls (for example, (100 shots per minute) is automatically changed to a second shot ball number (for example, 120 shots per minute) having a larger number of shot balls than the normal shot ball number.

<Operation> Accordingly, in the ball-and-ball game machine according to claim 1, the firing drive means for controlling the driving of the firing device to fire the ball is controlled by the firing number control means of the firing control means by a predetermined number per unit time. The number of fired balls per unit time controlled by the number-of-fired control means is controlled by the number-of-fired change control based on a game mode signal related to the control of the electric gaming apparatus from the game control means. By means, the number of shooting spheres per unit time is automatically changed and controlled.

Further, in the ball game machine according to claim 2, a special game state signal is the game mode signal output from the game control means, and based on the input of the signal, the firing number change control means, Since the number of fired balls per time is automatically changed from the first fired ball count as the normal fired ball count to the second fired ball count larger than the normal fired ball count, the The number of balls that can be fired per unit time in the special game mode in which the winning device is opened automatically increases.

A rear grip portion 27 having a handle shaft 26 is protruded, and a front grip portion 28 is provided with a space in front of the rear grip portion 27.
And a pivoting operation unit 29 attached to the distal end of the handle shaft 26 is rotatably disposed within a space between the rear gripping unit 27 and the front gripping unit 28 so that a finger hook of the pivoting operation unit 29 is provided. The first pulley 31 and the pressing portion 33 acting on the starting switch 32 of the firing device 12 are provided at the rear end portion of the handle shaft 26 protruding into the interior of the covering decorative member 25. A linear transmission member 34, such as a wire, which is wound around one end, is hung on the second pulley 35, and the other end of the linear transmission member 34 is wound around the third pulley 36 and fastened.

The turning operation unit 29 and the handle shaft 26 are made conductive and connected to a touch switch circuit via a lead wire 37, and it is electrically determined that the player touches the turning operation unit 29 and the like. To be detected.

Further, the third pulley 36 is connected to the connecting portion of the above-described firing device 12.
19 has a hole 38 that can be engaged and disengaged, and has one end connected to one end of a biasing member 39 such as a coil spring, and a stopper piece 41 that comes into contact with a stop projection 40 protruding from the back surface of the covering decorative member 25. is there.

In order to attach the firing operation unit 9 having the above-described configuration to the front frame 2, the positioning projections 42 projecting from the rear surface of the covering decorative member 25 so as to cover the opening of the front frame 2 from the front surface.
Are inserted into the positioning holes 43 on the front surface of the front frame 2 to determine the mounting position, and fastening members 44 such as bolts projecting from the back surface of the covering decorative member 25 are attached to the through holes of the front frame 2 and the firing substrate 13. A nut is screwed into a male screw portion that penetrates into the mounting hole and protrudes from the firing substrate 13 to integrally tighten the covering decorative member 25, the front frame 2, and the firing substrate 13. When the firing operation unit 9 is mounted at a predetermined position in this way, the connection portion 19 of the firing device 13 engages with the hole 38 of the third pulley 36 of the firing operation unit 9.

Therefore, when the player touches the rotation operation unit 29 of the firing operation unit 9, the touch switch circuit 45 is turned on, and when the rotation operation unit 29 is turned, the start switch 32 of the firing device 12 is turned on.
And the stepping motor 22 of the firing device 12 starts, the firing rod 16 reciprocates, and the firing position 46 at the lower end of the firing rail is inclined.
Bounce off the ball.

Next, a mechanism for adjusting the number of shots of the firing device 12 will be described.

The number-of-firing-balls setting means 48 as the number-of-firing-change control means provided in the electric control device 47 controls the number of firing spheres per unit time in the firing device 12 in accordance with the game state, and controls the number of the firing spheres. The number of launch balls per unit time in the launch device 12 is changed by the launch control device 49 that has received the instruction from the number setting means 48.

That is, the number-of-launched balls setting means 48 and the launch control device 49
Thus, it functions as a launch control unit that performs launch control of the launch device 12. Note that the launch ball number setting means 48 is not provided in the electric control device 47, and the launch control value 49 is not provided.
It may be provided inside.

The launch control device 49 basically includes an oscillation circuit 50, time interval setting means for receiving an output from the oscillation circuit 50 and outputting a signal at a preset rate (set time interval), and time interval setting means. From the number-of-launched signals set by the number-of-launched-balls setting means 48. In the basic embodiment shown in FIG.
The frequency divider 51 is used as time interval setting means, and the first AND gate 52 and the second AND gate 53 are used as emission number signal alternative control means.
The touch switch circuit 45 and the start switch
A third AND gate 54, a fourth AND gate 55, and a fifth AND gate to operate the firing device 12 when the switch 32 is ON.
There are 56 etc.

In the embodiment of the drawing, the output shaft 23 of the stepping motor 22 is
The firing rod 16 is actuated one time each time the motor rotates once to fire one ball at the firing position. The stepping motor 22 receives 200 pulses and rotates the output shaft 23 once (one pulse). An output shaft that rotates 1.8 degrees is used. The oscillation circuit 50 oscillates at a frequency of 4433619 Hz. Therefore, the frequency divider 51 sets the frequency division ratio to 11091,13312 in advance, receives the signal from the oscillation circuit 50, and sets the number of emissions to 10
A signal of 99.92 pulses per minute (first firing number control signal) as a signal for 0 signals and a signal of 120 firings per minute as a signal for 120 signals per minute
A 9.92 pulse signal (second firing number control signal) is output. If the frequency division ratio of the frequency divider 51 is set appropriately, the rotation speed of the stepping motor 22 can be set appropriately, and is not limited to the above numerical value.

When the number of shots per minute is set by a command from the number of shot balls setting means 48 during the progress of the normal game, an "H" signal from the first flip-flop 57 is output to the first AND gate 52.
Enter one input side of. The first AND gate 52 is a frequency divider
Since the signal from the first flip-flop 52 is used as the other input, when "H" from the first flip-flop 52 is input, the signal is opened each time "H" and "H" from the frequency divider 51 are input.
A firing number control signal is output and sent to one input of the third AND gate 54.

The third AND gate 54 uses the output of the fifth AND gate 56 as the other input. Therefore, the fifth AND gate
If the input side from 56 is "H", that is, if the player touches the firing operation unit 9 to turn on the start switch 32 of the firing device 12, the third AND gate 54 is opened and Peripheral
The first firing number control signal from 51 is sent to a motor drive circuit 58 as firing driving means.

The motor drive circuit 58 sends a pulse signal to the stepping motor 22 according to a signal from the third AND gate 54. Therefore, the stepping motor 22 operates at a speed of 100 revolutions per minute, whereby the firing rod 16 fires 100 balls per minute (the first number of fired balls).

Next, when a special game that is more advantageous for the player than the normal game starts, and the number of shots per second (the second number of shots) is set by an instruction from the number of fired balls setting means 48, , The “H” signal from the second flip-flop 59
Enter one input side of the AND gate 53. Since the second AND gate 53 receives the signal from the frequency divider 51 as the other input, when “H” from the second flip-flop 59 is input, this “H” and “H” from the frequency divider 51 are input. Is opened each time, the second firing number control signal is output and sent to one input side of the fourth AND gate 55.

The fourth AND gate 55 receives the output of the fifth AND gate 56 as the other input. Therefore, if the player touches the firing operation unit 9, the fourth AND gate 55 opens and sends the second firing number control signal from the frequency divider 51 to the motor driving circuit 58, and the motor driving circuit 58 Circuit 58 sends a pulse signal to stepper motor 22 in response to the second firing rate control signal.
Accordingly, the stepping motor 22 operates at a speed of 120 revolutions per minute, whereby the firing rod 16 fires the balls at a rate of 120 balls per minute.

As described above, the launch control device 49 includes a launch ball number setting unit.
The rotation speed of the stepping motor 22 is changed according to the signal from 48, and the firing device 12 is controlled so as to fire balls at time intervals corresponding to the number of shots set by the shot ball number setting means 48. That is, in the present embodiment, the oscillation circuit 50, the frequency divider 51, the first and second AND gates 52, 53, and the like cooperate to function as a firing number control unit.

As described above, in the present invention, since the number of shot balls is controlled using the signal from the oscillation circuit 50, stable and reliable control can be performed. Therefore, even when the number of shooting balls is regulated by law, it is possible not only to set the number of shooting balls reliably within the range of regulation, but also to set an arbitrary number of shooting balls (for example, from 100 It is also possible to set a smaller number of firing spheres.

The hit balls fired at the time intervals selected by the number-of-fired-balls setting means 48 as described above enter the game unit 4 on the surface of the game board 3 from the firing rail via the guide rail. In addition, the flight distance of the hit ball can be adjusted according to the amount of rotation of the rotation operation unit 29 operated by the player. That is, when the rotation angle of the rotation operation section 29 is small, the rotation angle of the third pulley 36 is small, so that the rotation amount of the gear 20 of the firing device 12 connected to the third pulley 36 is also small, so that the fan-shaped The force applied to the urging member 17 by the rotation of the gear 18 is also small. Therefore, after the cam 24 of the stepping motor 22 presses the arm 21 to rotate the rotary plate 15, when the cam 24 comes off the arm 21, the rotary plate 15 is biased by the biasing member 17. The force of turning back,
That is, the force by which the firing rod 16 rotates toward the firing position 46 is weak,
For this reason, the flight distance of the hit ball is shortened. On the other hand, when the rotation amount of the rotation operation unit 29 of the firing operation unit 9 is increased, the sector gear 18
Is increased, and the force applied to the urging member 17 increases, so that the force for rotating the firing rod 16 increases in accordance with the amount of rotation of the rotation operation unit 29. For this reason, the flight distance of the hit ball is
It expands according to the amount of rotation of.

 Next, the variable winning device 5 will be described.

The variable winning device 5 shown in the drawing has an opening 61 substantially at the center of a substrate 60 mounted on the surface of the game board 3, and the opening 61
A horizontally long box-shaped armor portion 62 is projected from the surface of the substrate 60 above, and a natural prize opening 63 is formed on the upper surface of the armor portion 62, and stands upright on the left and right sides of the opening 61. A pair of movable pieces 64, 64 that can be converted into a first state that is disadvantageous for the player by preventing the inflow of the ball and a second state that is advantageous for the player by receiving the ball by tilting the upper end outward. Are rotatably supported by the support shafts 65, 65, and a blocking wall 66 functioning as a blocking member is provided below each movable piece 64. At the lower edge of the opening 61, the lower end portions of both blocking walls 66, 66 are provided. The front decorative plate 67 is provided so as to be connected. And the case on the back side of the substrate 60
68, a concave chamber 69 is formed, and the bottom of the concave chamber 69 is formed.
A plate-like first partition member 71 and a second partition member 72 which are long in the front-rear direction are disposed below the 70 at intervals slightly larger than the diameter of the sphere. The first partition member 71 and the second partition 72 are pivotally mounted on the lower surface of the bottom surface 70 of the recessed chamber 69 by a shaft 73 in the middle of the length of 72, respectively, between the lower end portions of both blocking walls 66, 66. The first general winning opening 74 is formed between the lower end portion of the one blocking wall 66 and the front end portion of the first partition member 71 by facing each front end portion of the member 72, and the first general winning opening 74 is formed between the front end portion of the first partition member 71 and the first A special winning opening 75 is formed between the front end of the second partitioning member 72 and a second general winning opening 76 is formed between the front end of the second partitioning member 72 and the lower end of the other blocking wall 66. A special prize detector 77 is placed in the flow path where the ball entering the mouth 75 flows down,
A counting detector 78 is provided in a flow path in which a ball entering the first general winning opening 74 and the second general winning opening 76 and a ball entering the special winning opening 75 and acting on the special winning detector 77 flow down. In addition, the first partition member
A small decorative plate 7 is provided at the tip of the first partition member 71 and the tip of the second partition member 72, respectively.
The small decorative plates 79, 79 are exposed in the cutouts of the front decorative plate 67. Accordingly, when the first partitioning member 71 and the second partitioning member 72 swing, the small decorative plates 79, 79 at the distal end move in the left and right directions different from each other in the cutout portion to approach or separate from each other.

Further, on the back side of the substrate 60, as described above, a concave chamber 69 whose bottom surface 70 is slightly inclined downward toward the opening 61 is formed, and a doll is provided on a front wall portion in the concave chamber 69 by support shafts 80, 80. The doll 81 is provided so as to be vertically movable, and a shelf-shaped ball guide plate 82 is provided in front of the doll 81 so as to be slightly inclined downward toward the interior of the concave chamber 69. A movable piece drive mechanism for driving the movable piece 64, a partition member drive mechanism for driving the first partition member 71 and the second partition member 72, and a doll for driving the doll 81 are provided behind the concave chamber 69. A drive mechanism and the like are provided.

As shown in FIG. 9, the movable piece driving mechanism mounts two first solenoids 84, 84 as electric driving sources on a driving source mounting plate 83 provided on the back side of the concave chamber 69, and The connecting rod 85 is fixed to the plunger, and one end of a spring 86 is connected to the connecting rod 85 to urge it.
A crank-shaped rotating rod 87 is fixed to the other end of the support shaft 65 to which the shaft is attached, and a pin 88 of the rotating rod 87 is loosely fitted into the hole 89 of the connecting rod 85 described above. Therefore, when the first solenoids 84 are demagnetized, the movable pieces 64 are erected by the bias of the springs 86 to prevent the ball from entering the recessed chamber 69, that is, flow down the gaming section 4. This is the first state in which the sphere that does not enter the concave chamber 69. Thus, in the first state, each movable piece 64 has a portion that protrudes downward from the left and right sides of the armor portion 62,
In addition, it also functions as a blocking member in connection with the blocking wall 66. On the other hand, when each of the first solenoids 84 is excited, the plunger is raised against the bias of the spring 86, and the rotating rod 87, the support shaft 65, and the movable piece 64 are rotated substantially 90 degrees. Each movable piece in this way
When the ball 64 rotates in the direction in which the upper end is tilted outward, the ball that has flowed down in the game section 4 is received on the movable piece 64 and is guided to the ball guide plate 82, that is, the ball is converted into the second state in which the ball can be easily received. . In the second state, the ball received by each movable piece 64 rolls on the ball guide plate 82 toward the depth of the concave chamber 69,
It falls on the bottom surface 70 of the concave chamber 69 through the gap between the lower end of the ball guide plate 82 and the front wall of the concave chamber 69, and rolls toward the opening 61 due to the downward inclination of the bottom surface 70, 1,2nd general winning opening 74,7
Enter either 6 or the special winning opening 75. Thus, in the second state, each movable piece 64 functions as a sphere introduction unit that introduces a sphere into the concave chamber 69. And each first solenoid
When the magnet 84 is demagnetized, the plunger is lowered by the bias of the spring 86 and the support shaft 65 is returned and rotated. Therefore, the movable piece 64 is rotated back and does not receive the ball from the sideways second state in which the ball is easily received. It returns to the upright first state.

The partition member drive mechanism shown in FIGS.
It drives not only the first and second partition members 72 but also the decorative members 90, 90 provided on the left and right sides of the substrate 60. The base plate 91 provided immediately behind the concave chamber 69 serves as an electric drive source. A motor 94 with a reduction gear is mounted, and a cam 94 is attached to an output shaft 93 of the motor 92. Drive pins 95, 95 protruding from the rear ends of the first partitioning member 71 and the second partitioning member 72 are connected to the cam 94, respectively. It is loosely fitted in a substantially elliptical groove 96 at a position shifted by about 180 degrees around the output shaft 93. In the vicinity of the cam 94, a first photosensor 97 and a second photosensor 98 are provided as first and second detecting means with a phase change of substantially 90 degrees, and projecting from the outer peripheral surface of the cam 94. The piece 99 acts on the first photosensor 97 and the second photosensor 98. As shown by the dotted line in FIG. 11, the above-mentioned substantially elliptical cam 94 always stops with the short diameter portion of the groove 96 directed in the vertical direction and the long diameter portion in the horizontal direction. Acts on the sensor 97. In the first state, since the drive pins 95 of the first partition member 71 and the second partition member 72 are fitted in the long diameter portion of the groove 96, the leading end portion of the first partition member 71 and the second partition member 72 And the width of the special winning opening 75 is minimized, and the width of the first general winning opening 74 and the second general winning opening 76 is maximized. Note that the special winning opening 75 is slightly wider than the ball diameter even if the width is minimum, so that the ball can be sufficiently won. When the motor 92 is operated by a signal from the electric control device 47 and the cam 94 is rotated substantially 90 degrees clockwise in FIG. 11, the drive pin 95 of the first partition member 71 and the second partition member 72 are rotated. The groove 96 into which the drive pin 95 fits moves, and the two drive pins 95, 95 are fitted while relatively moving to the short diameter portion of the groove 96, and the protrusion 99
Acts on the second photo sensor 98 to send a signal to the electric control device 47, and based on this signal, the electric control device 47 stops the operation of the motor 92 and stops the rotation of the cam 94. Therefore, the distance between the two drive pins 95, 95 is reduced, whereby the first partition member 71 and the second partition member 72 rotate in different directions about the shafts 73, 73, respectively. The interval between the portion and the distal end portion of the second partition member 72 is gradually enlarged, and the above-mentioned interval, that is, the width of the special winning opening 75 is maximized when the cam 94 is rotated approximately 90 degrees. The width of the first general winning opening 74 and the second general winning opening 76 is reduced to a minimum. When the cam 94 is rotated by approximately 90 degrees in this manner, the state is changed to the second state in which the width of the special winning opening 75 is maximum and the width of the first general winning opening 74 and the second general winning opening 76 is minimum. . Therefore, the probability of winning a ball to the special winning opening 75 increases, and the probability of winning a ball to the first general winning opening 74 or the second general winning opening 76 decreases.

When the cam 94 is rotated in reverse by rotating the motor 92 in reverse according to a signal from the electric control device 47, the width of the special winning opening 75 between the first partition member 71 and the second partition member 72 gradually decreases. . Then, when the projecting piece 99 acts on the first photosensor 97 and sends a signal to the electric control device 47, the electric control device 47 stops the operation of the motor 92 based on this signal,
The state returns to the first state where the width of the special winning opening 75 is minimized.

As described above, when the cam 94 is rotated by the operation of the motor 92 of the partition member drive mechanism, the first and second partition members 71 and 72 move to change the width of the special winning opening 75.

Note that the partition member drive mechanism moves the first partition member 71 and the second partition member 72 constituting the special winning opening 75, and moves the special winning opening.
The configuration is not limited to the driving of the cam 94 as long as the effective width of 75 can be changed, and any configuration may be used. For example, the driving may be performed by a solenoid via a link mechanism.

As shown in FIG. 10, the doll drive mechanism has a second solenoid 100 provided as an electric drive source on the back side of the base plate 91, and swings in the middle of the length by the shaft 101 while penetrating the base plate 91. The moving rod 102 is pivotably mounted on the shaft, and the
One end of the support shaft 80 faces the plunger of the second solenoid 100, and the tip of the support shaft 80 projecting backward from the doll 81 is engaged with the other end of the swinging rod 102. Therefore, the second
When the solenoid 100 is intermittently excited, the plunger reciprocates up and down and reciprocally swings the swinging rod 102.
The swing of 02 moves the doll 81 up and down. As described above, when the doll 81 can be moved up and down by driving the second solenoid 100, when the game state is changed in the game, the doll 81 can be moved up and down so that the player can visually display the fact. Not only that, the decoration effect can be enhanced.

Further, in the embodiment of the drawings, the hanging of a curtain 103 as a variable display member in the concave chamber 69 can also inform the player of the change of the game state. The mechanism for driving the curtain 103 is a long lower plate 1 on the upper surface of the concave chamber 69.
04 and an upper plate 105 shorter than the lower plate 104.
A guide member having a guide groove formed in the lower plate 104 is provided in the front-rear direction, and a slide plate 106 is provided in the guide groove so as to be movable in the front-rear direction.
Is connected to one end of a curtain 103, and a pinion gear is attached to an output shaft of a motor 107, and the pinion gear 108 meshes with a rack gear 109 on the upper surface of the slide plate 106. And
Photosensor 11 for detecting the position of slide plate 106
0 and 111 are provided at the rear end of the upper plate 105 and the rear end of the lower plate 104, and the light shielding pieces 112 and 113 are provided in the middle and at the rear end of the slide plate 106. Therefore, the vertical curtain 103 can be lowered or raised by moving the slide plate 106 back and forth by rotating the motor 107 forward and backward.

Next, an electric control device 47 constituting a game control means for controlling the variable winning device 5 having the above-described configuration will be described.

The electric control device 47 includes an electric control device such as a microcomputer as shown in FIG.

Next, a game in the pachinko machine 1 provided with the variable winning device 5 having the above configuration will be described. In a normal state, both movable pieces 64, 64 of the variable winning device 5 are stopped in an upright state and the ball is not accepted, and a special game right generation and continuation winning hole (a so-called V hole). It is assumed that the special winning opening 75 functioning as is in the first state having the narrowest width.

In the state where the ball fired in the game section 4 does not win any of the prize devices and the normal game is performed, the number of the launch devices is set to 100 per minute by the command from the launch ball number setting / writing means 48. 12 fires a ball. Then, the ball fired by the firing device 12 flows down in the game section 4, and this ball is luckily
Upon entering the starting port 6, the first starting detector 119 detects this ball and sends a signal to the electric control device 47. Electrical control device 47
Receives the signal from the first start detector 119, rotates the motor 92 of the variable winning device 5 in the normal rotation direction. Motor 92
Is rotated in the forward direction, the cam 94 rotates and the protruding piece 99 comes off the first photo sensor 97, so that the first photo sensor
When the cam 97 is turned off and the cam 94 is further rotated and the protruding piece 99 acts on the second photosensor 98, the second photosensor 98 is turned on and sends a signal to the electric control device 47. The motor
The speed and the like of the motor 92 are set in advance so that the time required from the start of rotation of the 92 to the stop by the action of the second photosensor 98 is 0.75 seconds. In this way the cam 94
Is rotated approximately 90 degrees, the first partition member 71 and the second partition member
72 swings to convert the special winning opening 75 from the first state in which the ball winning probability is low to the second state in which the width is wide and the ball winning probability is high. The time required from the start of rotation of the motor 92 to the stop by the action of the second photo sensor 98 is set to 0.75 in advance.
The speed and the like of the motor 92 are set to be seconds. When the cam 94 stops, that is, the second photo sensor 98
When the electric control device 47 sends a signal to the first solenoid 84 of the variable winning device 5 for a predetermined short time (for example, 0.
Excitation is performed only once (for 5 seconds), and the movable pieces 64, 64 change from the first state, which is disadvantageous to the player, to the second state, which is advantageous to the player. In this manner, the movable pieces 64, 64 of the variable winning device 5
Is changed from the first state to the second state, the ball flowing down in the game section 4 does not flow down on the movable pieces 64, 64, or the ball flowing down in the game section 4 is a movable piece 64, 64, the ball rolls on the ball guide plate 82, and then rolls on the bottom surface 70 of the concave chamber 69 toward the opening 61, and the first and second general winning openings
If the ball enters any one of 74 and 76 and does not enter the special winning opening 75, the movable pieces 64 and 64 return by the demagnetization of the first solenoid 84 and rotate to receive the ball from the second state where the ball is easily received. Return to the first state. In addition, the motor 92 of the variable winning device 5 is operated after a predetermined time elapses according to a signal from the electric control device 47 to return the special winning opening 75 from the wide second state to the narrow first state. In the embodiment shown in the drawings,
After a lapse of a predetermined time from demagnetization of the first solenoid 84 (for example, 2.8 which is preset in the timer 118 of the electric control device 47).
(After a lapse of two seconds), the motor 92 is rotated in the reverse direction to rotate the cam 94 back, and the cam 94 is sufficiently rotated to return the special winning opening 75 to the first state in which the width is narrow. It is configured to act on the first photosensor 97 and stop when the first photosensor 97 is turned on. In this manner, the special winning opening 75 is widened for a while not only while the movable pieces 64, 64 are changing from the first state to the second state, but also until the movable pieces 64, 64 return to the first state. The second state is that the movable pieces 64, 64
This is because the time it takes for the ball received by the player to flow down in the recessed chamber 69 and win the special prize port 75 or the general prize ports 74 and 76 is added so as not to be disadvantageous to the player.

When the ball that has flowed down in the game section 4 luckily enters the second starting port 7, the second starting detector 120 detects this ball and sends a signal to the electric control device 47. The electric control device 47
Upon receiving the signal from the second start detector 120, the motor 92 of the variable winning device 5 is rotated in the normal rotation direction, and
The special winning opening 75 is converted from the first state in which the ball winning probability is low to the second state in which the ball is wide and the ball winning probability is high. The speed and the like of the motor 92 are set in advance so that the time required from the start of rotation of the motor 92 to the stop by the action of the second photo sensor 98 is 0.75 seconds. And cam 94
Is stopped, that is, when a signal is sent from the second photo sensor 98, the electric control device 47 causes the first
Apply the solenoid 84 to a predetermined short time (for example, 0.8 seconds) 2
Excitation is performed only once, so that the movable piece 64, 64 changes only twice from the first state, which is disadvantageous to the player, to the second state, which is advantageous to the player. Thus, even if the movable pieces 64, 64 of the variable winning device 5 are changed from the first state to the second state, the gaming unit 4
If the ball flowing down does not flow down on the movable pieces 64, 64, or the ball flowing down in the game section 4 becomes movable pieces 64, 64
If the movable piece 64, 64 flows down and is introduced into the recessed chamber 69 and does not enter the special winning opening 75 due to winning in the general winning opening 74, 76, the movable piece 64, 64 returns due to the demagnetization of the first solenoid 84. The first state in which the ball is not accepted from the second state in which it is easy to accept the ball by moving
Returns to the state. In addition, the motor 92 of the variable winning device 5 is operated after a predetermined time elapses according to a signal from the electric control device 47 to return the special winning opening 75 from the wide second state to the narrow first state. In the embodiment shown in the drawing, similarly to the above, after a predetermined 2.8 seconds elapses after the demagnetization of the first solenoid 84, the motor 92 is reversely rotated to return the cam 94 to rotate. Then, the cam 94 is sufficiently rotated so that the special winning opening 75 has a narrow width.
The state returns to the state, and the protrusion 99
And stops when the first photosensor 97 is turned on.

On the other hand, when the movable pieces 64, 64 of the variable winning device 5 change from the first state to the second state, the sphere that has flowed down in the game section 4 flows down onto the movable pieces 64, 64, and this ball is guided by the ball. After rolling on the plate 82, it rolls on the bottom surface 70 of the concave chamber 69 toward the opening 61, and when luckily entering the special winning opening 75, the special winning detector 77 detects this ball and electrically A signal to the effect that a special game right has been generated is sent to the control device 47.

When the electric control device 47 receives the signal from the special prize detector 77, the launch ball number setting means 48 sets the number of launch balls in the special game state and sends a command to the launch control device 49, and the launch device 12 Fire a ball at 120 shots per minute. That is, in the present embodiment, by setting a signal indicating that a special game right has been generated in the game mode signal, during the execution of the special game, the set value of the number of balls that can be bounced is 120 shots per minute. The settings are changed.

In addition, the second solenoid 100 is intermittently excited so that the doll 81
Is moved up and down, and the geared motor 107 is operated to drop the curtain 103 into the recessed chamber 69, thereby visually displaying the start of the special game to the player. Note that the doll 81 continues to move up and down during the special game, but the curtain 103 is
Immediately after being hung in 9 is raised.

In the special game in this embodiment, the movable pieces 64, 64 of the variable winning device 5 are
1), the cycle is changed from the first state to the second state, and the cycle is updated on condition that the ball enters the special winning opening 75 during this cycle, and the cycle is updated up to eight times. If the ball does not enter the special winning opening 75 even after the movable pieces 64, 64 have been changed from the first state to the second state up to the 18th time in the cycle, regardless of the number of remaining cycles, The special game is set to end. Even if the number of winning balls to the variable winning device 5 reaches a predetermined number (for example, 10), no ball enters the special winning opening 75, or the movable pieces 64, 64 are moved a predetermined number of times (for example, 18).
If the ball does not enter the special winning opening 75 after only opening and closing operations, the special game is terminated at the end of the cycle.

Then, the number-of-launched balls setting means 48 sets the number of launched balls in the normal game state, sends a command to the launch control device 49, and causes the launch device 12 to launch 100 hits per minute.

In the present embodiment, in order to increase the continuation probability of the special game, it is set so that the ease with which the ball enters the special winning opening 75 during the special game is changed. That is, as shown in the timing chart of FIG. 14, when the ball wins the special winning opening 75, the special winning opening 75 is in the wide second state in which the ball can easily enter. The special winning opening is once returned from the wide second state to the narrow first state by reversing the motor 92 in response to the signal. Then, the number of winning balls to the variable winning device 5 is a predetermined number (for example, 4
), Or the number of times of opening and closing operations of the movable pieces 64, 64 reaches a predetermined number (for example, nine times).
Is changed from the narrow first state to the wide second state. 14th
In the timing chart shown in the figure, when the number of winning balls reaches a predetermined number of four, the state in which the motor 92 rotates forward and the width of the special winning opening 75 is widened is indicated by a solid line, and the number of times the movable pieces 64, 64 are opened and closed is nine. The state in which the motor 92 rotates forward and the width of the special winning opening 75 is widened is indicated by a dotted line. As described above, in the special game in which the number of shots is 100 per minute, it is set so that the ball is hard to enter the special winning opening 75 in the first half of one cycle and is easy to enter in the second half.

Either the number of winning balls to the variable winning device 5 reaches a predetermined number of ten, or the movable piece 64, 64 performs the opening and closing operation a predetermined number of 18 times, whichever one of the end conditions is satisfied. The special game ends when the ball does not enter the special winning opening, or when a predetermined number of continuations (eight cycles) are executed and the end condition in the final cycle is satisfied. In this case, when a continuation detection effective time (for example, 2.8 seconds) preset in the timer 118 elapses, the motor 92 of the variable winning device 5 reversely rotates the cam 94 by the signal from the electric control device 47 and rotates. Then, the special winning opening 75 is returned from the wide second state to the narrow first state. Then, the number-of-firing-balls setting means 48 sets the number of firing spheres in the normal game state and sends a command to the firing control device 49.
Fire a hit ball. That is, in the present embodiment, the end of the special game is also considered to correspond to the special mode, and with the end of the special game, the number of resilient balls increases to 100 per minute.
It is set to change from the start.

It should be noted that the number of launch balls per unit time in the launch device 12 is not limited to the above, and can be changed as appropriate by changing the frequency division ratio of the frequency divider. The driving source of the launching device may be any driving source as long as it can electrically drive the launching device.
A rotary solenoid or the like can also be used.

Further, the present invention can be applied to any pachinko machine capable of performing a special game that is more advantageous to a player than a normal game.

<Effect of the Invention> As described above, according to the bullet game machine of the first aspect, the firing drive means for controlling the driving of the firing device to fire the ball is controlled by the firing number control means of the firing control means. ,
A predetermined number of balls are controlled so as to be able to be fired per unit time, and the number of fired balls per unit time controlled by the number-of-fired control means is based on a game mode signal relating to control of the electric game machine from the game control means. Therefore, the number of shot balls per unit time is automatically changed and controlled by the shot number change control means, so that the number of shot balls is changed to an appropriate number of shot balls according to the game mode, A satisfying game can be provided irrespective of the skill of the player.

For example, in a game mode in which a variable prize device, which is an electric game device, is open, a player obtains more game profit by changing the setting so as to increase the number of fireable balls per unit time. In a game mode in which the prize memory for the starting port is already full, the number of shot balls per unit time is reduced, so that the game profit in a state where the game profit that can be acquired is smaller than in the normal state is reduced. Loss of the player can be suppressed, and it can be prevented that the winning in the starting opening becomes invalid and the player is dissatisfied.

Further, according to the ball game machine according to claim 2, the special game state signal is the game mode signal output from the game control means, based on the input of the signal, the firing number change control means, Since the number of fired balls per unit time is automatically changed from the first fired ball count as the normal fired ball count to the second fired ball count larger than the normal fired ball count, The number of balls that can be fired per unit time in the special game mode in which the changed prize device is opened is automatically increased, and the variable prize device in the special game state is not greatly affected by the player's playing skill. , It is possible to increase the amount of profit obtained by the player based on the winning ball.
