Abstract

PURPOSE: To surely prevent a phenomenon that a hit ball is discharged into a play area again and becomes an out ball when it is caught by a movable element and guided into a prize winning space, by forming an obstruct part for changing a flow- down state of a hit ball on the guide plane of a movable element. CONSTITUTION: A hit ball P1 flowing down along a guide plane 72a tries to pass through a flow-down direction variable projecting element part 74a at a high speed but its flow-down speed is decelerated by the flow-down direction variable projecting element part 74a. Besides, when the hit ball falls at low speed, its flow-down is stopped by the flow-down direction variable projecting element part 74a and with the changes of opening/closing wing elements 53a into closed state, that ball naturally falls into a prize winning space 87. As the other execution example of the obstruct part, plural recessed parts 75a-75c are formed on the guide plane 72a, the hit ball flowing down along the guide plane 72a touches these recessed faces 75a-75c and its flow-down speed is decelerated so that the hit ball can be surely guided into the prize winning space 87. Further, even when projecting parts are formed on the guide plane 72a in place of recessed parts for decelerating the flow-down speed of the hit ball, the similar effect can be provided as well.

Description

Detailed Description of the Invention "Industrial Application Field" The present invention provides a variable winning ball device that partitions a gaming area and a winning space and is provided with a pair of movable pieces that are mounted on opposing shafts with a predetermined interval. In particular, the present invention relates to a variable winning ball device for a pinball game machine, which is characterized by the structure of the movable piece.

"Conventional technology" Conventionally, in pinball game machines such as pachinko machines and arrangement-type pachinko machines that play by shooting pachinko balls,
Many variable winning ball devices are provided that include a pair of movable pieces that partition a gaming area and a winning space. As a typical example of such a variable winning ball device, a pair of opening/closing wings are provided as a pair of movable pieces, and winning balls guided by the opening/closing wings change the falling direction within a relatively wide winning space. An example is a variable winning ball device that flows down and enters any one of a plurality of winning holes provided below a winning space and which gives different values.

The variable winning ball device as described above has a first state in which the pair of opening/closing wings are opened in a substantially horizontal direction to receive and receive a hit ball, and a first state in which the pair of opening and closing wings are opened in a substantially vertical direction to receive and receive a hit ball, and a first state in which the pair of opening and closing wings are erected and closed in a substantially vertical direction to receive and receive a hit ball. It is designed to open and close repeatedly at relatively short time intervals, and when the opening and closing blades are in the first state, the winning balls placed in the receiver will be distributed among the above-mentioned multiple winnings. In your mouth,
When a prize is won in a preset specific winning slot, a specific game state is entered, and the opening/closing wing is operated under predetermined conditions (generally, until the opening/closing wing is opened/closed 18 times or until there are 10 winning balls: hereinafter referred to as the opening/closing cycle). ) is established, and this state can be repeated several times (e.g., 8 times) as long as there are winning balls in a specific winning slot, so that a large amount of prize balls can be won. I was trying to give them a chance to win.

"Problems to be solved by the invention" By the way, in the above-mentioned conventional variable winning ball device,
Since the guiding surface for guiding the ball on one of the opening/closing wings is composed of a substantially linear flat surface, when the opening/closing wing is in the first state, the ball that falls onto one of the opening/closing wings The ball quickly jumps over the winning space and onto the other opening/closing wing, and then jumps out from the other opening/closing wing into the gaming area, and the ball that should have been the winning ball passes laterally through the winning space. There were many cases where the ball was out.

In particular, in the case of a device that can be repeated a predetermined number of times, such as the above-mentioned variable winning ball device, the 18 opening and closing movements of the opening and closing wings are performed at the end of the opening and closing cycle until 10 winning balls are generated. If a hit ball that should have won a prize passes through, the possibility that the ball that should have won a prize is guided to a specific winning hole and the opening/closing cycle continues is eliminated, resulting in extremely disadvantageous results for the player. There was a case.

This invention was made in order to eliminate the above-mentioned inconvenience, and its purpose is to provide a variable winning ball device equipped with a pair of movable pieces, in which a ball that is once received by the movable piece is To provide a variable prize winning ball device which is surely guided to a winning space and does not cause balls to jump out to a game area again.

"Means for Solving the Problems" In order to achieve the above-mentioned object, the present invention is provided with a pair of movable pieces that partition a gaming area and a winning space, and that are mounted on opposite shafts with a predetermined interval. The variable winning ball device is characterized in that a guide surface of the movable piece that guides the hit ball from the gaming area to the winning space is provided with an obstacle portion that changes the falling state of the hit ball.

Next, a variable prize winning ball device according to an embodiment will be explained based on FIGS. 1 to 9. First, the overall configuration of the variable winning ball device will be explained with reference mainly to FIGS. 1 and 4. FIG. 1 is a front view of the variable winning ball device 50, and FIG. 4 is an exploded perspective view of the entire device. In the figure, a mounting board 51 attached to the game board 6 has a rectangular window opening 54 formed therein. An upside-down U-shaped winning restriction portion 55 is formed protrudingly along the upper opening edge of the window opening 54, and the winning restriction portion 55 is formed by an upper front decorative plate 56 screwed onto the front surface thereof. The normal winning opening 52 is formed on the upper side. In addition, at the lower ends of both left and right sides of the winning regulation part 55, there are opening and closing wings 53.
Current transformation protrusions 55a and '55 projecting outward from a and 53b

A U-shaped winning ball receiving frame 58 that covers both side edges and the lower edge of the window opening 54 is formed protruding from the lower front surface of the mounting board 51 . On the front of this winning ball receiving frame 58,
A lower front decorative plate 59 is screwed onto the mounting board 51 with screws. The lower front plate 59 has a ball insertion hole 6 for inserting pachinko balls from the front into a specific winning opening 63a, which will be described later.
0 and a rotation shaft 68a of the opening/closing wing pieces 53a and 53b, which will be described later.

Shaft covers 59a and 59b covering the front surface of 68b are integrally formed. When testing the variable winning ball device 50, the ball insertion hole 60 described above is artificially inserted into the specific winning hole 6.
Used when throwing pachinko balls into 3a. Also,
An upper ball transfer plate 61 extending rearward is screwed and fixed to the upper part of the lower front decorative plate 59 with screws. This upper ball transfer plate 61 transfers the winning balls guided by the opening/closing wings 53a and 53b toward the rear of the winning space 87.

A pair of standing walls 62a and 62b are erected in the front and back direction on the lower side of the entered prize ball receiving frame 58, and the three areas partitioned by the standing walls 62a and 62b are a specific winning slot 63a in the center and a general winning slot 63b on the left and right sides. .

It is 63c. And, the specific winning opening forming member 64 that defines the size of the specific winning opening 63a is the standing wall 62a, 6
It is designed to be detachably attached to the tip projections 65a, 65b of 2b. That is, the engagement holes 64a and 64b drilled in the specific winning opening forming member 64 are connected to the vertical wall 6.
After fitting into the tip projections 65a, 65b of 2a, 62b, the lower front decorative plate 59 is screwed onto the mounting board 51, thereby fixing the specific winning opening forming member 64. Thereby, the specific winning a prize opening forming member 64 can be replaced extremely easily.

The vertical walls 62a and 62b are erected up to a rear circumferential wall 66 that is formed to protrude rearward along the opening edge of the window opening 54 of the mounting board 51, and a specific prize opening 63 is provided at the rear end.
A winning ball flow path regulating plate 67 that causes the winning balls to flow downward is fitted. Further, the rear peripheral wall 66 constitutes a side wall of a winning space 87, which will be described later, but a portion is cut out, and that portion is filled with other members to constitute a side wall of the winning space 87 as a whole. It's like that.

Above the entered prize ball receiving frame 58, opening/closing wing pieces 53a, 53
b is rotatably supported. Opening/closing wing pieces 53a, 53
b, the rotation shafts 68a and 68b are screwed in from the front.
9a and 69b, and the rotation shaft 68a
, 68b are inserted into and supported by rotation bearing sleeves 70a and 70b integrally formed with the mounting board 51. Note that plastic bearing members 71a to 71d (71a and 71b are not shown) are fitted into the front and rear of the rotational bearing sleeves 70a and 70b to stably support the rotational shafts 68a and 68b.

In addition, guiding surfaces 72a, 72b are formed on the opening/closing wings 53a, 53b to catch and stop the balls falling in the game area 8, and a locking protrusion 73a is formed at the tip of the guiding surfaces 72a, 72b.
, 73b are provided protrudingly, and a downward direction variable projecting piece 74 is provided at the base end.
a and 74b are provided in a protruding manner. This locking protrusion 73a,
73b and the downward direction variable projecting pieces 74a, 74b have a function as an obstacle that changes the downward flow state of the ball flowing down the guide surfaces 72a, 72b, and are shown in FIGS. 2A and 2B.
The operation will be explained with reference to the drawings.

FIG. 2A shows the action of the variable flow direction projecting piece 74a, in which (a) shows a state where the opening/closing wing pieces 53a, 53b are opened almost horizontally (open state), and (b) shows an opening/closing state. The blades 53a and 53b are shown in the process of transitioning from the closed state to the open state or from the open state to the closed state. First, to explain the case where a hit ball falls forcefully onto the guiding surface 72a, the hit ball P flowing down the guiding surface 72a, (second
The pachinko ball (indicated by the - dotted chain line in Fig. A) attempts to pass through the variable flow direction protrusion part 74a with great force, but the flow direction variable protrusion part 74a slows down the flow rate and the momentum is reduced. Since the ball P1 is weakened and the direction of flow is changed from horizontal to diagonally upward, the ball P1 will surely fall into the winning space 87 without reaching the guiding surface 72b of the other opening/closing wing 53b. . Furthermore, when the ball falls on the guide surface 72a at a slow speed, the ball P2 (the pachinko ball shown by the solid line in FIG. 2A (a)) flowing down the guide surface 72a is 74a to stop the flow, and the flow direction variable projecting piece 7
4a, as the opening/closing wing piece 53a transitions to the closed state, the downward direction variable projecting piece part 74a
It will fall naturally into the winning space 87. Furthermore, if a hit ball falls onto the guiding surface 72a of the opening/closing blade 53a during opening/closing, regardless of whether the speed is fast or slow, the hit ball p3 (pachinko ball shown by the solid line in FIG. 2A(b)) ) will be flowed diagonally downward into the winning space 87, and in this case as well, it will surely fall into the winning space 87.

On the other hand, FIG. 2B shows the action of the locking projecting piece 73a, which shows that the locking protrusion 73a flows down the guide surface 72b of the other opening/closing wing 53b and jumps over the winning space 87.
The ball P4 that has reached the guiding surface 72a hits the locking protrusion 73a protruding from the tip of the guiding surface 72a, and its flowing direction is changed to the opposite direction, and the ball P4 enters the winning space 87 from the guiding surface 72a. The player will not be guided into the game area 8 again. Therefore, also in this case, the hit ball P4 can be reliably guided to the winning space 87.

In this embodiment, both the locking protrusion 73a and the variable flow direction protrusion 74a are formed on the guiding surface 72a, but the above effect can still be obtained even if only one of them is formed. In particular, in the case of this embodiment, since the downward direction variable projecting piece 74a is provided at the base end,
The majority of hit balls are guided to the winning space 87 almost reliably, and the number of hit balls that are guided from the guiding surface 72a to the winning space 87 is determined by the falling speed of the balls riding on the guiding surface 72a. The falling state of each ball is different, and it is possible to realize a more interesting flowing state of the ball.

FIG. 3 is a partial front view of the variable winning ball device showing another example of the obstacle portion formed on the guiding surface 72a. In this embodiment, the guiding surface 72a has a plurality of concave portions 75a to 75a.
75c is formed, and the balls flowing down the guiding surface 72a come into contact with the concave surfaces 75a to 75c, and their falling speed is reduced, thereby ensuring that they are guided into the winning space 87. Note that at least one concave portion 75a to 75c is sufficient, and the same effect can also be obtained by forming a convex portion on the guiding surface 72a instead of the concave portion to reduce the falling speed of the ball. Obtainable.

The winning regulating part 55, the winning ball receiving frame 58, and the opening/closing wing pieces 53a and 53b described above partition the winning space 87, which will be described later, of the variable winning ball device 50 and the gaming area 8. In order for the ball to win, open and close wings 5
3a and 53b must perform opening and closing operations.

The rear peripheral wall 66 is cut out on the left and right sides of the center of the mounting board 51, and the cutouts include decorative space forming inner members 76a, 76b and decorative space forming outer members 77a, 77b.

The foot decoration part 117 supported in this manner is configured such that the engagement pin 119 formed in the foot decoration part is engaged with the foot engagement hole 114 formed in the vertical sliding plate 110, and the foot decoration part 117 is vertically slidable. By vertically moving the moving plate 110, the legs are folded (see FIG. 5) and the legs are extended (see FIG. 6). In addition, when the upper part of the foot decoration part 117 rotates, it affects the flowing state of the winning prize which moves toward the center of the winning space 87, and the above distribution is made by the member 115.
a and 115b, they change the flow of balls in the winning space 87 to make the game more interesting.

Next, the drive mechanism for sliding the vertical sliding plate 110 will be explained. A motor 120 is screwed onto the rear surface of the decorative member mounting plate 90, and a rotating cam 122 is attached to the motor shaft 121 of the motor 120. Fixed. An eccentric engagement pin 123 is protruded from the rotating cam 122 at a position eccentric from the shaft 121, and the eccentric engagement pin 123 engages with an engagement groove 112 formed on the back surface of the vertical sliding plate 110. It looks like this. Therefore, when the motor 120 rotates,
The engagement between the eccentric engagement pin 123 and the engagement groove 112 allows the vertical sliding plate 110 to slide in the vertical direction. Then, when the vertical sliding plate 110 slides in the vertical direction,
The above-mentioned sliding spherical portion 101b1 arm decoration portion 106a, 1
06b, the members 115a, 115b, and the foot part 117 are arranged to operate. The rotary cam 122 also has a thin semicircular plate 124 on half of its outer circumference.
are integrally formed, and the semicircular plate 124 rotates and passes through the groove of a photosensor 125 fixed to the upper part of the decorative member mounting plate 90.

This photosensor 125 is of a light emitting/receiving type, and while the semicircular plate 124 is passing through the photosensor 125, the
It is in the FF state, and the others are in the ON state.

The rotation of the motor 120 is stopped by detecting that the photo sensor 125 changes from ON to OFF or from OFF to ON.

The above-described dynamic decorative member 100, as described later, is configured such that when the variable winning ball device 50 enters a specific gaming state, the specific winning hole 63
It is set to operate every time there is a winning pressure in a, during that interval and in the middle of the opening/closing operation of the opening/closing blades 53a, 53b.

Note that V reception valid display LEDs 95a and 95b are screwed onto the decorative member mounting plate 90 at the lower left and right sides thereof. These ■ reception valid display LEDs 95a and 95b indicate that the opening/closing wing pieces 53

Furthermore, a wiring relay board 99 is fixed to the upper part of the decorative member mounting plate 90. This wiring relay board 99 includes the decorative LED 57, the motor 120, and the photosensor 125.
, and wiring for solenoids 128a and 128b, which will be described later.

Behind the decorative member mounting plate 90 is a drive source mounting plate 12.
6 is screwed on. A solenoid 128a is attached to the rear surface of this drive source mounting plate 126 via a metal mounting plate 127.

Engagement members 129a, 12 fixed to plunger b
9b engages with engagement pins 130a, 130b fixed to the rear ends of the rotating shafts 68a, 68b, thereby causing the opening/closing wings 53a, 53b to open/close. That is, when the solenoids 128a and 128b are excited, the engaging members 129a and 129b rise, thereby rotating the rotation shafts 68a and 68b, so that the opening and closing blades 53a,
53b is in an almost horizontal position and opened, solenoid 12
When 8a and 128b become de-energized, the engaging member 129a
, 129b are lowered, thereby rotating the rotation shafts 68a, 68b.
rotates in the opposite direction to raise the opening/closing blades 53a and 53b into a closed state.

The drive source mounting plate 126 is provided with decorative lamps 131a and 131b that decorate the rear surface of the decoration space and decorative LEDs that decorate the rear surface of the distribution members 115a and 115b.
A wiring relay board 1 that connects the wiring of the lamp 132, the LED lamps 80a and 80b, and the decorative LED lamp 132.
33 etc. is attached.

As is clear from the above, the variable winning ball device 5
The opening/closing wing pieces 53a, 53b of 0 have their guiding surfaces 72a, 7
Since the locking protrusions 73a, 73b and the downward direction variable protrusions 74a, 74b or concave portions 75a to 75c are formed on the 2b, the winning pressure induced into the winning space 87 by the opening/closing wings 53a, 53b is reduced. is reliably prevented from jumping out into the game area 8 again, and the possibility of continuation of the opening/closing cycle allowed for the variable prize winning ball device 50 is reliably guaranteed.

13 to 15 are flowcharts showing the operation of the control circuit shown in FIG. 12.

Next, the specific operation of this embodiment will be explained with reference to FIGS. 1 to 15.

When the control circuit is powered on, the microcomputer 150 initializes the contents of the RAM 153 (step Sl) and waits for the next signal. Pachinko machine 1
When the game is started and a pachinko ball is hit into the game area 8 of the game board 6, the microcomputer 150
First, it is determined whether or not the driven pachinko ball has entered the starting winning hole 11 (step S2). This is the starting winning ball detection switch 31 (
This is accomplished by sending a detection signal from the starting winning ball detection switch 2 (hereinafter referred to as starting winning ball detection switch 2 in this flowchart) to the microcomputer 150.

If it is determined that the starting winning ball detection switch 2 is not turned on, it is determined whether or not a prize has been won in another starting winning hole 12a, 12b, that is, starting winning ball detection switch 32a, 3.
It is determined whether or not 2b (starting winning ball detection switch 1; hereinafter referred to as starting winning ball detection switch 1 in this flowchart) is turned on (step S3). In step S3, if it is determined that the starting winning ball detection switch 1 is not activated, the process returns to step S2. On the other hand, if it is determined that the starting winning ball detection switches 2 and 1 are ON in step S2 and step S3, the microcomputer 150 drives the solenoids 128a and 128b via the solenoid circuit 165 to , 53b to open and close twice or once at relatively short time intervals, and furthermore, the RAM
153 is cleared, and the display contents of the digital display 81 and the digital display 82 are initialized via the digital display drive circuit 169 (step S4).
and step S5). Next, the opening/closing wing pieces 53a, 53
It is determined whether or not a pachinko ball is guided to the opening/closing wings 53a, 53b while V is opening/closing, and the winning ball enters the specific winning hole 63a and activates the V winning ball detection switch 34 (step S8). ■If it is determined that the winning ball detection switch 34 is turned on, the opening/closing wing piece 53a
, 53b is in progress, the contents of the opening/closing process are cleared (step S7) and the process proceeds to the process shown in FIG.

On the other hand, in step S6, the opening/closing wing pieces 53a, 5
If it is determined that the winning ball guided by 3b is not turned on, the winning ball detection switch 34 is not turned on, the starting winning holes fl, 12a, 12b of the opening/closing wing pieces 53a, 53b.
It is determined whether one or two opening/closing processes have been completed (step S8), and if it is determined that they have not been completed, the process returns to step S8 and the V detection process is performed. On the other hand, if it is determined that the opening/closing process has been completed, the measurement of the reception valid time (approximately 2 seconds) will start, which guarantees the validity of the V winning after the opening/closing process is completed.
In order to notify players of this, ■ Reception valid display LED
95a and 95b are turned on via the LED circuit 168 (step S).

). The microcomputer 150 performs the following processing even within this effective time. That is, it is determined whether or not the starting winning ball detection switch 2 is turned on (step 5IO), and if it is determined that it is turned on, the process proceeds to step S to turn off the reception valid display LEDs 95a and 95b.
++), then return to step S4. If it is determined that the starting winning ball detection switch 2 is not turned on, it is determined whether the starting winning ball detection switch 1 is turned on (step Sl□). In this step s12, if it is determined that the starting winning ball detection switch 1 is turned on, ■ reception valid display LED 95a, 95
bfP-Turn off the light (step 5I3), and then return to step S5. In addition, the starting winning ball detection switch 1 is OFF.
If it is determined that the winning ball detection switch 34 has not been turned on, it is determined whether or not the winning ball detection switch 34 has been turned on (step S!4). If it is determined in step SI4 that the V winning ball detection switch 34 is ON, ■ the reception valid display LEDs 95a and 95b are turned off (step SI4).
s), proceed to the process shown in FIG.

On the other hand, in step S14, if it is determined that the winning ball detection switch 34 is not turned on, it is determined whether or not the reception valid time has elapsed (step S51).
6) If the time has not elapsed, the process returns to step S1 and repeats the processes from step 0 to step S16. In addition, when ■ the reception valid time has passed, ■ the reception valid display LEDs 95a and 95b are turned off (step 81).
7)% Then -, return to step S2 and repeat the subsequent processing.

First regarding the process when the V winning ball detection switch 34 is activated in step S and step SI5.
This will be explained based on FIG. First, when the 1 winning ball detection switch 34 is activated, a so-called specific game state is entered, and the starting winning ball detection circuit 161 is disabled (step s,
6). This means that even if the batted ball in the game area 8 enters the starting prize openings 11, 12a, 12b in a specific game state,
This means that the winnings are treated as invalid and priority is given to the specific gaming state. Next, "1" is added to the value of the continuation number counter in the RAM 153 (step 51).
9) A number corresponding to the value is lit on the digital display 81 for displaying the number of continuations via the digital display drive circuit 169. Thereafter, in order to accurately drive and control the predetermined game value or to process the interrupt routine shown in FIG. 15, counting is started for a predetermined preparation period (about 2 to 5 seconds) (step S2 ).

Then, after the predetermined preparation period in step S20 has elapsed, the memory contents of the 10 count counter are cleared again (step 521). After each of the above processes is completed, the microcomputer 150 sends a drive signal to the solenoid circuit 165, so that the solenoid 128a,
128b is driven (step 522). Since this drive signal is given as a pulse signal having a minute time width, the solenoids 128a and 128b alternately repeat energization and de-excitation. For this reason, the opening/closing wing piece 53a.

53b repeats opening and closing operations at minute time intervals, but the number of opening and closing operations is limited to a maximum of 18 times. The opening/closing time interval of the opening/closing wings 53a, 53b may be different from the opening/closing time interval of one or two openings/closings due to winning of the starting prize openings 11, 12a, 12b. , may be the same. Furthermore, the time interval between the first half and the second half of the 18 opening/closing operations may be changed.

When the above-described opening/closing operations of the opening/closing wings 53a, 53b are performed, the hit ball falling in the game area 8 is directed to the opening/closing wings 53a.
, 53b, and the guided winning pressure enters the winning space 87. Then, it is determined whether the winning pachinko ball passes from the upper work transfer board 61 to the lower work transfer board 85 and enters the specific winning opening 63a, that is, whether or not the V winning ball detection switch 34 is turned on. (Step 523). And V winning ball detection switch 3
If it is determined that 4 is ON, it is determined whether the value of the continuation number counter is "8" or not.
24), if the value is not "8", the opening/closing operation of the opening/closing blades 53a, 53b is immediately cleared (step 52S), and then the process returns to step 5l11,
The processing from step S19 onwards is repeated again.

On the other hand, if it is determined in step S24 that the value of the continuation number counter is "8", the V winning is treated as invalid (step 328), and the process proceeds to the next step S27. In step S27, if it is determined in step S23 that the V winning ball detection switch 34 is not turned on, and if the process in step S26 is finished, all the winning balls in the variable player prize ball device 50 are It is determined whether the number of winning balls is 10 or less. This determination is also made based on whether the value of the 10 count counter included in the RAM 153 is "10" or not.

If the value of the 10 count counter is not "10", it is determined whether the number of opening/closing operations of the opening/closing blades 53a, 53b is 18 (step 528);
If it is determined that the number of times has not reached 8, the process returns to step S23 and the processes of steps 323 to 5211 are repeated. On the other hand, if it is determined in step S27 that the value of the 10 count counter is "10", or in step S28, the opening/closing blades 53a, 5
If it is determined that the number of times the opening/closing blade 3b has reached 18, the opening/closing operation of the opening/closing blades 53a, 53b for that time is terminated as a predetermined condition is satisfied (step 52).
9), then proceed to the next process.

In step S29, when the opening/closing operation of the opening/closing wings 53a, 53b is completed, the starting winning ball detection circuit 161, which was disabled in step 5l11, is activated again, and each starting winning ball detecting switch 2 and 1 is activated. Then, in step 53o), the validity of the V winning is guaranteed after the opening and closing of the opening/closing wings 53a and 53b is completed.■Starting the measurement of the reception valid time (approximately 2 seconds), and notifying the player to that effect.

, 95b are turned on via the LED circuit 168 (step S3□). The microcomputer 150 performs the following processing even within this effective time. That is, it is determined whether the starting winning ball detection switch 2 is turned on or not (step S3), and if it is determined that it is turned on, ■ reception is enabled is displayed and the ED95a, 95b is turned off in step S3), and then , return to step S4.

In addition, if it is determined that the starting winning ball detection switch 2 is not turned on, the starting winning ball detection switch 1 is turned on.
It is determined whether or not (step 534). In this step S34, if it is determined that the starting winning ball detection switch 1 is turned on, the ■ reception valid display LED 9
5a and 95b (step 535), and then returns to step S5. Further, if it is determined that the starting winning ball detection switch 1 is not turned on, it is determined whether or not the 7 winning ball detection switch 34 is turned on (step 336). If it is determined in step S36 that the V winning ball detection switch 34 is ON, it is determined whether the value of the continuation number counter is "8" (step S36).
37) If it is determined that the value of the continuation number counter is not "8", ■ Turn off the reception valid display LEDs 95a, 95b (step 538), return to step S16, and open/close the opening/closing blades 53a, 53b again. Repeat the opening and closing operations. Further, if it is determined that the value of the continuation number counter is "8", the ■ winning prize is treated as invalid (step 539).

On the other hand, if it is determined in step 33B that the 7 winning ball detection switch 34 is not turned on, and if the winning is invalidated in step 539, it is determined whether or not the reception valid time has elapsed. is determined (step 54o), and if it has not elapsed, the process returns to step S32. □ to step S4° are repeated. In addition, ■When the reception valid time has passed,
(2) Turn off the reception valid display LEDs 95a and 95b (step S4), then return to step S2, end the so-called specific gaming state, and repeat the subsequent processing.

Incidentally, the processes described above do not include the process for operating the dynamic decorative member 100, but the process for operating the dynamic decorative member 100 is performed by the interrupt routine process shown in FIG. Ru. The interrupt routine process shown in FIG. 15 is a process for operating the dynamic decorative member 100, and is processed so that it is always interrupted by a pulse signal from the interrupt pulse generation circuit 159 from the time the power is turned on. FIG. 15(a) shows a process for starting the rotation of the motor 120, and FIG. 15(b) shows a process for stopping the rotation of the motor 120. First, as a process for starting the rotation of the motor 120, it is determined whether or not the drive control preparation period elapse process in step 320 is in progress (step S42). If it is determined that the drive control preparation period elapsed process is not in progress, the opening/closing blades 53a, 53b
has been opened and closed 18 times or the number of prizes is 10
It is determined whether or not the opening/closing process has been completed since the opening/closing process has been completed (step 543). If it is determined that the opening/closing process of the opening/closing wings 53a, 53b in the specific game state has not been completed, it is determined whether the value of the 10 count counter in the RAM 153 has reached "5" ( Step 544), furthermore, the value of the 10 count counter is “5”.
”, if it is determined that the opening/closing blade 53 has not been reached.
It is determined whether the opening/closing operations of a and 53b have reached 10 times (step S4). If it is determined in step S4S that the number of openings and closings has not reached 10, the interrupt routine process ends.If all determinations are No in steps S42 to S45, the so-called specific game state is reached. In this case, it can be said that this is an interrupt IA filling performed during a normal game.

Further, if it is determined YES in step S42,
In other words, if there is a valid V winning, step S
If it is determined YES in step S43, that is, 18 opening/closing processes have been completed, and if it is determined YES in either step S44 or step S4S, that is, the predetermined operation cycle of the opening and closing blades 53a and 53b is completed. When the predetermined condition (5 winnings or 10 opening/closing operations) is satisfied, the microcomputer 150 sends a rotation start signal to the motor 120 via the motor circuit 166. In other words, the dynamic decorative member 100 operates in each of the above cases.

On the other hand, as the process of stopping the rotation of the motor 120, the processes of steps S47 to SKI shown in FIG. The relationship with the semicircular plate 124 is such that the photosensor 125 is turned on, that is, the semicircular plate 124 is not in the groove of the photosensor 125, and even if the motor 120 starts rotating, the motor 120 Since the rotation direction is clockwise rotation (counterclockwise rotation when viewed from the front of the variable winning ball device 50), the ON state of the photo sensor 125 continues until the motor 120 rotates 1/2. It has become. Under the above premise, first, it is determined whether the output from the photosensor 125 has changed from OFF to ON (step 547). If it is determined that there has been no change, it is further determined whether the photosensor 125 has changed from ON to OFF (step 548). Here too, if it is determined that there is no change, the interrupt ends. In step S48, the motor 120
If it is determined that the semicircular plate 124 has entered the groove of the photosensor 125 and turned off after rotating /2, it is determined whether the value of the 10 count counter has reached "5" (step 549), if it is determined that the opening/closing operation of the opening/closing blades 53a, 53b has not reached 10.
It is determined whether the number of times has been reached (step Sgo), and if it is determined that the number of times has not been reached, the interruption ends.

Further, if it is determined YES in step Sat, that is, if the motor 120 rotates once, step 3
49 or step S. Either of these has been achieved and YE
If it is determined to be S, that is, the opening/closing wing pieces 5'3a, 5
The output from the photosensor 125 changes from ON to OFF while the motor 120 is rotating due to the fulfillment of a predetermined condition (5 wins or 10 opening/closing operations) in the predetermined operation cycle of 3b. In this case, the microcomputer 150 sends a rotation stop signal to the motor 120 via the motor circuit 166. That is, in each of the above cases, the operation of the dynamic decorative member 100 is stopped.

The operation start and stop of the dynamic decorative member 100 described above will be further classified and explained in detail for each case as follows.

◎ Normal time Normal time is when there is no so-called specific gaming state,
In that case, a series of processing is performed: (a) start->S42->S43->S44->545-end (b) start-S4f->S48->end. Note that (a) represents the process shown in FIG. 15(a), and (b) represents the process shown in FIG. 15(b), respectively. The same information will be displayed below. Therefore, in normal times,
The dynamic decorative member 100 does not operate at all.

◎ Interval time Interval time means that the dynamic decorative member 100 operates as a demonstration when winning a prize.
In that case, (,) Start-S42→S46→End is processed and the motor 20 starts rotating.

On the other hand, in the process of stopping the rotation of the motor 20, the rotating cam 122 that rotates with the rotation of the motor 20 is halved.
When it rotates, a YES determination is made at 348 and S49
However, since the determination of No is made in both S49 and Sho, the motor 20 continues to rotate as follows: (b) Start - S4 f -> S48 -> S49 -> s5o -> End. Then, when the rotary cam 122 rotates once, a YES determination is made in S47, and the process proceeds to Sol. That is, (b) Start-S
4A→S51→End, and the motor 20 stops rotating.

In other words, during the interval, the dynamic decorative member 1o.

will operate once.

◎ During the 18th opening/closing operation The 18th opening/closing operation is when the processes from Steps 522 to S28 are performed, and in this case, whether 5 winning balls are generated in the variable winning ball device 50 or not. , or until the opening/closing blades 53a, 53b open/close 10 times, the same processing as in the normal time is performed. That is, (a) Start 4S42″S43″S44″S45″ End (b) Start-S4F → 548-End Then, when 5 pieces are won or it is opened and closed 10 times, (a) Start-34,- 1-543-* 544-+
(or S4, →) S46-End is processed and the motor 120 starts rotating.

On the other hand, when the rotary cam 122 has rotated 1/2, a YES determination is made in S48 and the process advances to S49, and further, S4. or S50, (b) Start-347→S4a→S49→(or S50).
5o→)Ss+→end, and the rotation of the motor 120 is stopped.

In other words, during the 18th opening/closing operation, the dynamic decorative member 1
00, the motor 120 starts rotating when 5 prizes are won or the opening/closing operation is performed 10 times, and the rotation is stopped when the motor 120 rotates by 1/2. Therefore, the dynamic decorative member 100 is in an activated state (stops at the position where the vertical sliding plate 110 is lowered, and the sliding spherical part 101b1, the arm parts 106a, 106b).
, the members 115a, 115b, and the foot decoration part 1
17 is in operation).

018th opening/closing end The 18th opening/closing end is when the process of step S29 is completed, and in this case, (a) start → S
4□→S43→546-end and motor 12
0 rotation begins.

On the other hand, when the motor 120 starts rotating, it is in a state where it has already made 1/2 rotation from the normal state (the dynamic decorative member 10
Motor 1 is stopped because motor 0 is in operation).
As a process for stopping the rotation of the rotary cam 122, when the rotary cam 122 has made another 1/2 rotation (when it returns to the normal state), YES is determined in S47 and the process proceeds to Sol.

That is, (b) Start-547=S! It is processed as +-end, and the rotation of the ♀-ta 120 is stopped.

That is, when the 18th opening/closing is completed, the dynamic decorative member ioo, which has been kept in the operating state, is returned to its original state.

In addition, the imperial decorative member 1 at the above-mentioned interval
Although it has been explained that the operation of 00 is performed once, this is the case where the opening/closing process is cleared 18 times in step S2S and there are 5 winnings, or the interval after the opening/closing operation is performed 10 times. As is clear from the explanation in each of the above cases, (a) Start-S4□→S46→End is processed and the motor 120 starts rotating, and (b) Start-347=
SS1→End is processed, and the rotation of the motor 120 is stopped.

In other words, it can be said that the movement of the dynamic decorative member 100 during the interval in this case is not once but 1/2 times until it is restored to its original state.

In the variable winning ball device 50 of the embodiment described above, when the hit ball drops forcefully onto the guiding surfaces 72a, 72b, the ball flowing down the guiding surfaces 72a, 72b is moved by the downward direction variable protrusion. Section 74a.

74b with great force, but the downward speed of the variable projecting pieces 74a and 74b reduces the velocity and weakens the force, and the downward direction changes from horizontal to diagonally upward. The ball can be reliably dropped into the winning space 87 without reaching the guide surfaces 72b, 72a of the other opening/closing wing pieces 53b, 53a.

On the other hand, the ball that flows down the guiding surface of the other opening/closing wing, jumps over the winning space 87, and reaches the guiding surface of one of the opening/closing wings is caught by the hooks protruding from the tips of the guiding surfaces 72a, 72b. When it hits the stop protrusions 73a and 73b, the flow direction is changed to the opposite direction, and the winning space 8 is flown from the guiding surfaces 72a and 72b.
7 and will not jump out to the game area 8 again.

Therefore, even in this case, the ball can be reliably guided to the winning space 87.

In particular, in the case of this embodiment, since the downward direction variable protrusions 74a and 74b are provided at the base end, the majority of the balls are almost certainly guided to the winning space 87, and the guiding surface 7
Depending on the falling speed of the balls riding on the balls 2a and 72b, the falling state of the balls when guided from the guide surfaces 72a and 72b to the winning space 87 differs, and it is possible to realize a more interesting flowing state of the balls. can.

In addition, in the above-mentioned embodiment, a pair of opening/closing wings 53a, 53b are illustrated as movable pieces, but the invention is not limited to this. good.

"Effects of the Invention" This invention provides a winning ball device equipped with a pair of movable pieces, in which an obstacle part is formed on the guide surface of the movable piece to change the falling state of the ball, so that the ball falls down the game area. When the ball is caught by the movable piece and guided to the winning space, the falling speed of the ball is reduced by the obstacle formed in the movable piece.
To surely prevent a phenomenon that is disadvantageous to a player, such as by changing the direction of flow and guiding the ball into a winning space, and then ejecting a ball that has once won a prize into the game area again and turning it into an out ball. be able to.
