Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable winning device for a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, as a variable winning device for a pachinko machine, a special member is provided with a movable member capable of converting a winning area (large winning hole) into a first state in which a game ball is difficult or unacceptable and a second state in which it is easily accepted. It is well known that a movable member is converted into a second state for a predetermined period when a game condition is satisfied so that a special game with a high winning rate is played.

[0003]

By the way, such a variable winning device is mounted by fitting a back constituent portion of the board rearward from the front into a mounting hole of the game board and screwing the board outer edge portion on the board surface. Therefore, the front side of the board (the surface part including the entrance of the winning area) will be exposed in the game area, but the board is made of synthetic resin that is easy to mold like many other components, The problem that some parts (areas that are likely to violently collide with a falling ball, such as the outer edge of the board and the entrance of the winning area) are likely to be worn or damaged due to collision with a ball that rolls violently in the game area was there. In particular, since the outer edge portion of the substrate forms a step (plate thickness) with the game board surface into a gentle taper surface, the plate thickness is thin like a cutting edge, so it is fragile and easily chipped by a collision with a game ball.

The present invention aims to solve such problems.

[0005]

Therefore, the present invention provides a variable winning device for a pachinko machine, which includes a movable member capable of converting a winning area into a first state in which a game ball is difficult or unacceptable and a second state in which it is easily accepted, As a mounting board on the surface of the game board that constitutes the surface portion of the entire device, a surface area that is likely to collide with the game ball vigorously is formed by a metal plating member.

Here, the metal-plated member is formed in a frame shape that covers at least the outer peripheral portion of the substrate and the surface area of the game ball, which is likely to collide with the game ball, including the entrance portion of the winning area.
Further, the metal plating member is configured to be separable from the constituent members forming other surface areas. Further, a hole for mounting a screw to the game board surface is formed in the frame-shaped metal plated member.

The guide member for supporting the movable member of the substrate is also integrally formed with a metal plated member.

[0008]

According to this, since the substrate is reinforced with the metal plating member in the surface area where the game balls are likely to collide with each other, it is possible to effectively prevent partial premature wear or damage due to the collision of the balls. The overall durability will be greatly improved.

In this case, if the metal-plated member is formed in a frame shape that covers at least the outer surface of the substrate and the entrance area of the winning area, which covers the entire surface area of the game ball that is likely to collide vigorously, this is a sturdy skeleton of the outer shape of the board. Thus, the rigidity of the entire substrate can be increased.

Further, if the metal plated member is configured to be separable from the constituent member forming the other surface area, not only the plating process of the member becomes easy, but also the advantage that the component can be replaced separately from the other constituent member is obtained. Be done.

Further, by forming the hole for the mounting screw with the game board surface in the frame-shaped metal plating member, it is possible to secure sufficient strength to withstand the tightening of the screw, and it may be chipped due to collision with the game ball. There is no need to do it. If the guide member that supports the movable member of the substrate is also integrally formed of a metal plated member, it is possible to easily secure the abrasion resistance and the like required for the member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, on a game board surface of a pachinko machine, a variable display device 3 for variably displaying symbols in a plurality of rows is provided in the center of a game area 2 surrounded by a guide rail 1, and a game ball is provided below it. When the variable winning device 4 that can be converted into an open state that is easy to receive is provided, and when the combination of the stop symbols of the variable display device 3 that operates based on the winning of the game balls starting openings 5a to 5c is a specific jackpot mode. The variable winning device 4 is converted into an open state so that a special game with a high winning rate can be played.

The starting ports 5a to 5c are formed at the upper center and the lower left and right of the center of the variable winning device 4. 6 is a winning entrance (general winning entrance) provided in the upper center of the game area 3, 7a, 7b
And 8a and 8b are sleeve winning openings (general winning openings) arranged on the left and right of the variable display device 3 and the variable winning device 4, 9a to.
9f is a windmill as a rolling guide member for the game ball, 10a,
10b is a variable display lamp that blinks brightly during the operation (display change) of the variable display device 3, 11 is an out port of the game ball, and 1
2 is a jackpot indicator lamp (which also serves as a failure indicator lamp) that blinks brightly when the right to play a special game occurs.
A decorative lamp (not shown) is housed inside each of a, 7b and 8a, 8b and the wind turbines 9a, 9b.

The variable display device 3 is composed of a liquid crystal display 15 and a protective frame 16 thereof, and is attached to the game board surface through the protective frame 16. A large number of decorative LEDs 17 and a storage indicator 18 for displaying the number of winning prizes stored in the starting openings 5a to 5b are arranged on the front upper portion of the protective frame 16 and are variable inside the cover portion 19 which surrounds these in an arc shape. During the operation of the display device 3, a plurality of variable display LEDs (not shown) that blinks brightly together with the decorative LED 17 are housed.

The memory indicator 18 is in this case four LEDs 1.
8a is provided, and when the winning in the starting ports 5a to 5b continues, the number of LEDs 18a corresponding to the number of times of storing (up to 4) is turned on. The variable display device 3 not only variably displays symbols in a plurality of lines on the liquid crystal screen 15, but also displays various characters and messages according to the game situation.

The variable winning device 4 is attached to the game board surface via the substrate 20 as shown in FIGS.
A special winning opening 21 is provided in the upper center of the front surface of the substrate 20.
The special winning opening 21 is formed in an upward gate shape (both ends are formed in a hook shape with guide surfaces that incline inward), and the entrance portions are formed at both skirts of the upper starting opening 5a. Each entrance 21a,
21b is provided with an opening / closing door 22 that can be converted into a closed state in which a game ball is not received and an open state in which it is easily received. A semi-cylindrical case (makeup lens) behind the special winning opening 21
A concave chamber 24 is formed by 25, and a pair of opening / closing blades 27 that partition the central continuous winning area A and the left and right general winning areas B are housed therein.

The opening / closing door 22 is provided on both sides of the starting opening 5a on the substrate 20.
It is composed of a pair of left and right door plates 22a that are freely slidable in the front-rear direction, and a connecting plate 22b that integrates these on the back side of the board 20. Both door plates 22a receive the game ball in the closed state and start left and right respectively. A gentle curved surface is formed so as to guide the rolling of the sphere toward the mouths 5b and 5c. The front end of each door plate 22a is formed into an inclined surface such as a cutting edge, and prevents the game ball from being caught and restrained between itself and the front glass of the game board when converting to the closed state.

A solenoid 30 drives the opening / closing door 22.
Thus, a joint 31 with the solenoid 30 is formed at the center of the rear end of the connecting plate 22b. The joint portion 31 has a locking hole 32 that opens upward (a vertically elongated U-shaped insertion groove 32
(comprising a) is formed, and the flange portion 26 at the tip of the plunger 33 is engaged with this. Joint part 31 and plunger 3
The engagement state with 3 is not rigid, and in order to prevent the drop impact of the game ball from being transmitted from the opening / closing door 22 to the solenoid 30 side, there is play between the tip of the plunger 33 and the locking hole 32 (with play). Is provided.

As shown in FIGS. 7 and 8, when the solenoid 30 is turned on, the opening / closing door 22 is converted into an open state by its exciting force, and when the solenoid 30 is turned off, it is returned to the closed state by the urging force of the return spring 34. Yes, the winning balls that flow into the special winning opening 21 while the opening / closing door 22 is open fall on the road surface of either the continuous winning area A in the center or the general winning areas B on the left and right, and slowly roll to form the concave chamber 24. Guided to the back.

In this case, since the opening / closing door 22 slides in the front-back direction of the substrate 20, there is no influence on the rolling of the game ball by playing the game ball along with the opening / closing. Also, the substrate 20
Since it requires almost no operating space on the surface, the degree of freedom in layout around the special winning opening 21 can be increased.

Further, the open / close door 22 and the solenoid 30 are in a connected state, but since they are connected directly without using a link, the solenoid 30 is required to have the same stroke as the open / close door 22. The operating force of the solenoid 30 is directly transmitted to the open / close door 22 (the loss of force is extremely small).
Therefore, the opening / closing door 22 can be advanced and retracted integrally with the driving of the solenoid 30 with good response.

Further, since the engaging hole 32 of the joint portion 31 and the flange portion 26 of the plunger 33 are simply engaged with each other from above in the front-rear positional relationship, the opening / closing door 22 and the solenoid 30 can be easily assembled. Moreover, as the link becomes unnecessary, the space on the back side of the substrate 20 can be effectively used and the solenoid 30 (coil portion) can be downsized.

In order to ensure good operability of the opening / closing door 22, in addition to the guide edge portion 40 which will be described later, the makeup lens 2 is also provided.
A guide wall 35 that horizontally supports the connecting plate 22b is provided on both sides of the upper part of the guide 5, and a guide groove 36 that guides the sliding of the connecting plate 22b in the front-rear direction is provided at the center thereof (see FIG. 5).

As shown in FIG. 4, the substrate 20 is a frame body 38 that forms a skeleton of an outer shape including the special winning opening 21 and the starting openings 5a to 5c (a region portion that is likely to collide with the game ball vigorously),
A guide edge portion 40 (a slit for inserting the door plate of the frame body 38) configured to include a front surface lens 39 (hard flat lens) fitted inside the lower portion thereof and supporting the sliding of the opening / closing door 22 on the back surface of the frame body 38. 41 is formed wide toward the rear),
A side wall 43 that surrounds internal lenses 48 and 49 described below is formed. The entire frame 38 is metal-plated (for example, chrome-plated) in order to ensure the strength to withstand the collision of game balls.

The outer edge of the frame 38 is formed as a gentle taper surface 38a from the upper edge to the side edge so as not to make a step with the game board surface. 38b is a hole portion of a screw for mounting on the game board surface.

The surface lens 39 is provided with bulging portions 44 and 45 at the central portion corresponding to the special winning opening 21 and both side portions corresponding to the left and right starting openings 5b and 5c, and a convex window at the center of the bulging portion 44. The portion 46 (enlarges the image of the cover lens 47 described later) is formed. On the back side of the surface lens 38, left and right general winning paths 51 are formed with a gentle downward slope toward the rear, and the opening / closing blades 27 are swingably supported via shafts 53 in the vicinity of the inside thereof.

A back plate 55 facing the front surface lens 39 is provided on the back surface of the frame body 38, and as shown in FIG.
The inner lenses 48 and 49 (the inner surface of which is not flat but forms a pattern with a large number of irregularities) are housed between the back plate 55 and the back plate 55.
The internal lenses 48 and 49 are provided with ridges 56 and 57 that fit inside the bulges 44 and 45 of the surface lens 39, respectively, and through the surface lens 38, a depth feeling is expressed on the front surface of the substrate 20. The inner lenses 48 and 49 are attached to the back plate 55 via the positioning pins 58 and 59 and the locking hooks 60 and 61, respectively.
The back plate 55 is screwed to the boss portion 62 on the back surface of the frame body 38 at the periphery.

A notch 65 having the same shape as the window portion 46 of the surface lens 39 is formed in the central lens 48, and a continuous lamp 66 that is brightly lit when the player continuously wins while the opening / closing door 22 is open while facing the notch 65. Back plate 55 with cover lens 47
Fixed to. The upper part of the lens 48 is formed in a shelf shape, and the center thereof is used as the continuous winning path 50, and the support surface 67 on which the general winning path 51 of the surface lens 39 is placed is provided on the left and right. On the surface of the continuous winning path 50, three guide protrusions 68 that guide two winning balls are formed in a gentle downward slope toward the rear.

The winning paths 70 of the starting openings 5b and 5c are provided above the left and right lenses 49, respectively.
The guide protrusion 71 of the strip is formed in a downward slope toward the rear. As shown in FIG. 9, the guide protrusion 71 is composed of a steep slope portion 71a immediately below the starting ports 5b and 5c and a gentle slope portion 71b following the steep slope portion 71a so that the winning ball is received by the steep slope portion 71a and quickly introduced. ..

As for the upper starting opening 5a, the whole including the winning path is integrally molded in the frame body, and as a winning path, a single guide projection 72 from the center immediately below the starting opening 5a is behind a gentle slope portion 72b continuing to the steep slope portion 72a. (The winning ball assembly gutter side on the back of the game board)
Is formed to extend to. A start winning switch (indicated by 74 in FIG. 13) for detecting a winning ball to the starting opening 5a is installed on the winning ball collecting trough side.

A pair of partition walls 77 are provided in the center of the back surface of the back plate 55 to divide the lead-out path (not shown) of the continuous winning area A and the general winning area B in the concave chamber 24. In order to support the continuous winning switch 80, a gutter wall 78 facing the partition wall 77 in the same direction and a continuous engagement groove 79 extending from the inner surfaces of the gutter walls 78 to the back surface of the back plate 55 are formed inside.

On the outer right and left sides of the partition wall 77, a support surface 82 of the general winning switch 81, a notch 83 corresponding to the detection hole of the switch 81, and a continuous locking from the outer surface of the partition wall 77 and the back surface of the back plate 55. Grooves 84 are formed respectively.
Reference numeral 85 denotes a window portion for illumination which is opened to the left and right inside the central lens 48.

Starting ports 5b and 5c are provided on the left and right sides of the back plate 55.
An approximately arc-shaped lead-out path 89 that is continuous with the prize-winning path 70 through the opening 88 is formed, and each lead-out path 89 is provided with a switch 90 for detecting a start winning ball. Starting prize switch 90
Is mounted on the flat portions on both sides of the lead-out path 89, and is detachably supported on the back plate 55 by the left and right locking hooks 91. There is some play between the locking hooks 91 in the left-right direction with respect to the switch 90.
Even if there is a slight deviation in the mounting position, the winning ball from the starting ports 5b and 5c hits the inside of the switch 90, so that the position is naturally adjusted.

Since this type of starting winning switch 90 has a certain direction with respect to the passage of winning balls, the harness 93 is pulled out from one side of the upper surface of the switch 90 so as not to make a mistake in assembling it on the back plate 55. A stopper 94 that restricts the setting direction of the switch 90 by using the harness 93 is provided on the back plate 55 in a protruding manner. The stopper 9
4 also functions as a hold-down of the upper end of the switch 90. 95 is a decoration lamp (opening / closing door 22) arranged at both ends of the back plate 55.
Also serves as a variable display lamp that flashes brightly when the
Then, it is attached to the cylindrical portion 96 that opens inside the left and right lenses 49.

The makeup lens 25 (the outer surface of which has a pattern of a large number of irregularities similar to the inner lens) is formed on the upper edge of the front surface on the back surface of the frame 38 of the substrate 20, and on the left and right flange portions 97 on the rear surface side. The recessed chamber 24 that is screwed to the boss 98 on the back surface of the back plate 55 and opens to the special winning opening 21, the bottom of the recessed chamber 24 is the continuous winning switch 80 in the center, and the right and left general winning switches 81.
Forming a lead-out path that opens downwards. A decorative lamp 100 (which also serves as a variable display lamp that blinks brightly while the opening / closing door 22 is open) is attached to each of the flange portions 97 through a hole 99 facing the window portion 85 of the back plate 55.

Incidentally, the continuous winning switch 80 is such that the front end side is inserted into the gutter wall 78 of the back plate 55 from the rear side of the makeup lens 25 and is supported by the locking groove 79, and the rear end is the locking hook 101.
The general prize switch 81
Are mounted on the support surface 82 of the back plate 55 from the side of the lens 25, and are held by the locking groove 84 while being held by the lower part of the inner wall of the concave chamber 24.

Then, the winning balls from the special winning opening 21 are guided to either the continuous winning path 50 or the general winning path 51, and to the outlet paths corresponding to these winning paths 50 and 51 at the inner part of the recess 24. It falls, and each falling ball is detected by the switches 80 and 81.

The shaft 53 of the opening / closing vane 27 is supported on the inner wall of the recessed chamber 24, and the fan-shaped guide holes 1 are provided above and below each supporting portion 102.
03 is opened. A link 105 that is slidable in the horizontal direction is provided on the back surface of the makeup lens 25 through the left and right locking grooves 104.
Are provided, and pin grooves (longitudinal grooves) 106 are formed on the upper and lower sides thereof. The opening / closing blade 27 is provided with insertion pins 107a and 107b into the upper and lower guide holes 103, respectively.
It is engaged with the pin groove 106 of the link 105 via 07a (formed in a vertically symmetrical positional relationship with respect to each support portion 102). Opposing walls 110 are provided at both ends of the link 105 so as to project rearward.
A solenoid 113 is arranged so as to abut the flanges 112 at both ends of the plunger 111.

As shown in FIGS. 11 and 12, the opening / closing blade 27 functions as a specific winning award guide member capable of converting the winning ball from the special winning opening 21 into the open state which is easy to receive in the continuous winning zone A and the closed state which is hard to receive. In this example, when the solenoid 113 is turned on, the link 105 is moved forward so that the continuous winning area A is widened to the full width of the special winning opening 21, and when the solenoid 113 is turned off, the link 105 is opened.
By the returning movement, the continuous winning area A is returned to the closed state in which the continuous winning area A is narrowed to almost the same width as the starting opening 5a.

In this case, the link 105 is the solenoid 11
When reciprocating in the horizontal direction integrally with 3, the insertion pin 107b rotates the pair of opening / closing blades 27 in opposite (left and right) directions while sliding along the pin groove 106 accordingly. Since the self-weight of the parts hardly acts in the operating direction of the solenoid 113, the loss of the force (exciting force of the solenoid 113 and the biasing force of the return spring 115) consumed for driving these is extremely small, and the wings 27 are opened and closed with good response. can do. Also,
Since the opposing wall 110 of the link 105 receives only a pressing force from the solenoid 113 in one direction, it is advantageous in terms of durability as compared with the case where pressing and pulling act alternately.

Further, the solenoid 113 and the link 105
In this connection state, since the flanges 112 of the plungers 111 are merely abutted against the opposing walls 110, even if the operating axes of the link 105 and the solenoid 113 are slightly deviated (inclination or the like), the operating force is applied to both wings 27. Since they can be transmitted evenly, the operability is hardly affected, and therefore the assembling of the solenoid 113 and the link 105 can be easily performed with a somewhat rough accuracy. Also,
The impact of the game ball falling from the opening / closing wing 27 is also solenoid 113
It is hard to reach the side.

At the base end of the opening / closing blade 27, there are two pachinko balls.
There is a possibility that ball clogging will occur when they are sandwiched side by side, and as a preventive measure, the depth width of the wings 27 is set to two balls, and a slight downward inclination in the depth direction is made at the lower end of the inner surface of both wings 27. It is good to attach it so that the balls can easily slip back and forth.

For the occurrence of a failure state in which the opening / closing blade 27 does not open, the special game is temporarily stopped as an example of the processing operation as described later, and at the time of completion of repair, the operator continuously wins a pachinko ball, Since the special game is restarted, a reset switch (indicated by 120 in FIG. 13) as a return condition is necessary, but the continuous winning switch 80 may also serve as this.

As shown in FIG. 6, a holding plate 121 of the link 105 is attached to the back side of the makeup lens 25 via a positioning pin 122, and a mounting plate 126 of a relay board 125 is screwed to a boss portion 134 on the back side of the holding plate 121. Be combined. The solenoid 113 is installed in the frame-shaped recess 127 of the holding plate 121, and is sandwiched between the solenoid 113 and the mounting plate 126 by screwing a heat sink (heat dissipation member) 128 to a boss portion 129 on the rear surface of the decorative lens 25. Decorative lamps 1 that illuminate the makeup lens 25 from the rear on the upper left and right sides of the holding plate 121.
30 (also serving as a variable display lamp that blinks brightly while the opening / closing door 22 is open) is provided, and the housing of the solenoid 30 is screwed to the upper portion of the heat sink 128 via a support piece 132.

Here, the heat sink 128 is mainly operated by the solenoid 30 (having a longer operation time than the solenoid 113,
This is for securing a heat radiation surface (having a large amount of heat generation), and since it contacts the opening end surface of the casing of the solenoid 113,
This can be effectively used as a heat radiation surface on the solenoid 30 side. Further, as the opening / closing door 22 moves back and forth, the connection step portion 22c (fluid resistance portion) between the door plate 22a and the connecting plate 22b.
By promoting the convection of air by the
It is possible to enhance the cooling effect on the solenoid 30 including the above.

If the heat sink 128 is made of a material having excellent heat conductivity and magnetism, the housing is attracted at least by the magnetic force of the solenoid 113, so that the solenoid 113 is sandwiched between the link holding plate 121 and a simple assembly structure. Nevertheless, a good contact state with the housing can be maintained. Reference numeral 135 is an opening for screwing the heat sink 128 from the rear of the mounting plate 126.

The relay board 125 includes solenoids 30, 113, lamps 66, 95, 100, 130, and a switch 8.
The wires 0, 81, 90 are concentrated, and are screwed to the boss portion 136 in a state of being positioned by the pin 137 on the rear surface of the mounting plate 126 as shown in FIG. A large number of harnesses are generally bundled into left and right parts, and
Wiring is performed along the lower wall 140 on the back surface so as not to disturb the user. The cover 141 also serves to suppress the wiring process.
Then, it is attached to the lower rear surface of the back plate 55 with screws via the boss portion 142 and the like.

The cover 141 has a concave shelf portion 144 for receiving a falling ball from each lead-out path of the concave chamber 24, the left and right starting ports 5b,
5 g, each of which has a gutter part 145 which is vertically connected to the outlet path, and the inner walls of both gutter parts 145 are the lower side wall 14 of the makeup lens 25.
A protective wall 146 that surrounds the left and right sides, and a restraining portion 147 for wiring processing that hangs from each protective wall 146 on the lower side of the lens 25 and covers the rear portion of the decorative lamp 100 are formed (see FIG. 6). Reference numeral 148 denotes a cover portion that covers the rear portion of the decorative lamp 95.

By the way, since the substrate 20 is reinforced by metal plating in the area where the game balls are likely to collide with each other, it is possible to effectively prevent partial early wear and damage due to the collision of the balls. Further, since the metal-plated portion (frame body 38) constitutes a sturdy skeleton of the outer shape of the substrate, the outer edge portion (taper surface 38a)
The rigidity of the entire substrate 20 can be improved as well as the protection of.

Since the frame 38 is separable from the surface lens 39, not only the member can be easily plated, but also the parts can be replaced separately from the surface lens 39. Further, the guide edge portion 40 of the opening / closing door 22 and the hole portion 38b for the mounting screw are integrally plated with the frame body 38, so that it is easy to secure high strength and wear resistance required for these.

Decorative lens 25 and internal lenses 48, 4
9 receives the illumination of the decoration lamps 130, 100, 95 to express a sense of depth (three-dimensional effect, volume effect) on the front surface of the substrate 20, and thereby a high decorative effect sufficiently high to enhance the taste of the game can be obtained. .. Further, the internal lenses 48 and 49 are protected by the hard surface lens 39 so that the balls do not hit and break, and the surface lens 39
Is flat, it is easy to clean dirt attached to the lens 39.

The frame 38 of the substrate 20 is effective not only for the decorative effect of producing a luster due to the metal plating but also for the noise countermeasure to the relay board 125 which is the farthest from the plating portion which is easily charged. There is also an advantage that the seal can be adhered to the glossy surface of the frame body 38 neatly.

Assembleability of the entire variable winning a prize device 4 can be easily carried out by sequentially superposing each component on the back side of the substrate 20 and screwing them together as described above, and disassembling it when replacing the component. Work can be done easily.

The special winning opening 21 and the starting openings 5a-5
The winning ball from c is guided to the collecting gutter on the back side of the game board via the shelf part 144 and the gutter part 145 of the cover 141, and is discharged from the collecting gutter to the collecting gutter behind the pachinko machine like various winning balls. is there.

A sound generator for generating sound, and 214 is an amplifier of the speaker 213.

Next, the control contents will be described based on the flowcharts of FIGS. FIG. 14 is a main routine, and FIG. 15 is an interrupt routine. The main routine and the interrupt routine start when the power is turned on.

In the main routine of FIG. 14, the I / O port and the RAM are initialized, and the game process is waited (1.01, 1.02). Starting openings 5a to 5c for game balls
When the start memory is generated based on the winning of the prize, the symbol variation (conversion display) of the variable display device 3 is started, and the number of times of the start memory is subtracted (-1) (1.03 to 1.0).
5).

When a predetermined time (for example, 5 seconds) elapses as the stop condition of the symbol variation or the stop switch on the front of the pachinko machine is turned on by the player's operation, the variation of the symbol is stopped and the combination of the stopped symbols is stopped. Is a specific jackpot mode (1.06 ~
1.08).

While the special game routine is executed only when the mode of the stop symbol is a big hit, these processes are repeated based on the starting memory when it is out (1.09, 1.1).
0).

In the interrupt routine of FIG. 15, the timer is updated in the main routine (for example, the symbol variation time of the variable display device 3 and the variation winning device 4 opening time) (2.
Along with 01), signals from various switches are read, and input determination processing is performed to confirm whether or not these switches are actually turned on (2.02, 2.03). The input determination is to prevent malfunction due to noise or the like, and the normality of the switch signal is determined when the same signal is continuously input from the same switch in two interrupt processes.

Further, based on the turning on of the starting winning prize switches 74 and 90, the starting winning prize process (2.04 to 2.06) for adding (+1) the maximum number of starting memories, and various sounds corresponding to the game mode. Output processing (2.07) and various lamp / LED display processing (2.08).

FIG. 16 shows a special game routine,
When the jackpot mode of the variable display device 3 is determined, the opening / closing door 22 of the variable winning device 4 is opened, and the opening / closing wing 27 is opened / closed except when the number of times of opening the special winning opening 21 is the final time.
Open in sync with 2 (3.01 to 3.03).

Normally, the opening / closing blade 27 opens to the full width inside the special winning opening 21, so the continuous winning switch 80 should be turned on before the general winning switch 81. If the first winning ball continues to win, the next time The right to continue the special game is generated, and the opening / closing blade 27 is closed to continue the lamp 66.
Is turned on (3.04 to 3.07).

When the general winning switch 81 is turned on first, it is determined that the opening / closing wing 27 is not opened for some reason, the opening / closing door 22 is once closed, and the pachinko machine failure display lamp 12 and voice output are performed. The player is informed of the occurrence of the failure by communicating with the management device 205 (3.04 → 3.08, 3.0).
9).

After the repair of the trouble is completed, when the worker continuously wins the pachinko ball as a return condition, the opening / closing door 22
Will be opened and the game will be restarted, and the operator's continuous winning will close the opening / closing blade 27 and light the continuous lamp (3.1.
0, 3.11 → 3.06, 3.07).

After the opening / closing door 22 of the variable winning device 4 is opened, the number of winning balls in the special winning opening 21 (the total number of times the continuous winning switch 80 and the general winning switch 81 are turned on) is counted 10 or a predetermined time (for example, After 25 seconds), the opening / closing door 22 closes to end one special game (3.12 to 3.14).

While the right to continue the special game is generated, the continuation lamp 66 is turned off (3.15, 3.16), and these processes are continued a predetermined number of times (for example, 16 times) on condition that the winning is continued.
This is repeated, and in the final round, the opening / closing blade 27 is kept closed and the right to continue the special game is not generated (3.02 → 3.12).

Further, FIG. 17 shows another special game routine, in which the general winning switch 81 is turned on before the continuous winning switch 80 when the number of times of opening the special winning opening 21 is other than the final number, When the failure state in which the opening / closing blade 27 does not open is determined, the opening / closing blade 27 is closed to notify of the occurrence of the failure, while the ON of the general winning switch 81 is considered to be the ON of the continuous winning switch 80 and the continuous lamp 66 is turned on. Yes (4.01 to 4.04 → 4.10 to 4.12 → 4.0
9).

As a result, the subsequent processing operation (4.13 to 4.17) is continued without waiting for the repair, and the continuous winning switch 80 is turned on before the general winning switch 81 during the next special game ( The failure state of the open / close blade may be restored naturally) and the normal routine (4.01 to 4.09 →
While returning to 4.13 to 4.17), the failure notification is automatically canceled (4.06, 4.07).

Next, the operation based on such a configuration will be described. In the gaming state, when the game ball wins the starting openings 5a to 5c, the symbol variation of the variable display device 3 is started, and the symbol variation is stopped after the elapse of a predetermined time. In addition, since the opening / closing door 22 of the variable winning device 4 guides the rolling of the ball on the curved surface, the gaming ball can win the left and right starting openings 5b and 5c relatively well.

This symbol variation is the start winning a prize switch 74,9
Based on the ON memory of 0 (starting memory), it is repeatedly executed at a predetermined cycle, and when the symbol display at the time of stop is a specific jackpot mode, the opening / closing door 22 of the variable winning device 4 is opened, and a special game with a high winning rate is performed. enter.

In this case, the opening / closing blade 27 is converted into an open state in synchronization with the opening / closing door 22 and the continuous winning area A is widened to the full width of the special winning opening 21, so that the winning ball to the big winning opening 21 is sure. Will be guided to the continuous winning zone A. Continuous winning switch 8
When 0 is turned on, the right to continue the next special game is generated, and the opening / closing wing 27 is returned to the closed state. The movement of this winning ball can be seen well from the front of the pachinko machine through the special winning opening 21, There is no fear or misunderstanding to the player. Further, while looking at the special winning opening 21, it is possible to easily confirm the generation of the right by turning on the continuation lamp 66 located immediately below.

Since the opening / closing wing 27 narrows the continuous winning area A to a width substantially the same as that of the starting opening 5a in the closed state, there is almost no winning in the continuous winning area A, but the right and left general winning areas B open relatively. Therefore, the winning balls from the special winning opening 21 successively flow into the general winning area, and the open / close door is closed when the continuous winning switch 80 and the general winning switch 81 have been turned on 10 times or a predetermined time has passed. The second special game is over.

Then, when the right to continue the special game is generated, the game shifts to the second special game, and since the opening / closing blade 27 opens in synchronization with the opening / closing door 22 as in the previous time, there is a considerably high probability (the big winning opening 21 The continuous winning rate occurs according to the winning rate). In this way, the special game can be repeated a prescribed number of times, and the player can obtain a large number of prize balls during this period.

Since the opening / closing wings 27 do not open in the final round of the special game regardless of the previous continuous winning, the player can know that the specified number of special games are all finished.

In this way, the special winning opening 2 of the variable winning device 4
Opening / closing blade 2 that divides the general winning area B and the continuous winning area A into 1
7 is provided, and as described above, this is converted to the open state so that continuous winning can be surely made, so even if a big hit occurs due to the stop pattern of the variable display device 3, the special game is repeated many times. It is extremely unlikely that the player will return to the normal game state before the game is played.

That is, the special game can be repeated with a very high probability (the right to the special game is generated whenever there is a winning ball in the special winning opening 21), so that the expectation of the player can be sufficiently satisfied. Can be made Also, the opening / closing blade 2
Since the probability of continuous winning can be adjusted by 7, the big winning opening 2
There is no need for subtle nail adjustments that invite continuous winning of game balls around 1.

The open / close wing 27 expands the continuous winning area A to the full width within the special winning opening 21 in the open state, but when the continuous winning switch 80 is turned on, it is returned to the closed state, and the continuous winning area A is almost the start opening 5a. By narrowing the width to the same width, the game balls flow into the general winning area B from both sides of the starting opening 5a, while the winning balls in the continuous winning area A are blocked by the starting opening 5a and hardly occur. It is possible to easily and accurately suppress the ratio of continuous winning to general winning during a special game within a substantially constant standard (currently 1/3 or less).

Since the opening / closing wings 27 are opened in synchronism with the opening / closing door 22, in response to the occurrence of a failure state in which both wings 27 are not opened, based on the signals from the general winning switch 81 and the continuous winning switch 80, The failure state can be easily and accurately determined by the sequence of these ON operations, and at the time of the determination, the general winning switch 81 is controlled to be ON to the continuous winning switch 80, so that the failure can be repaired without waiting. It is possible to continue the special game without any trouble (while ensuring continuous winning).

Regarding the positional relationship between the general continuation area B and the continuous prize area A in the special winning opening 21, the inside of the opening / closing blade 27 is set to the general prize area B and the outside is set to the continuous prize area A. The control pattern of the opening / closing blade 27 may be reversed from that of this embodiment, that is, the continuous winning may be ensured in the closed state. In that case, the failure state of the opening / closing blade 27 is a continuous winning ball to the continuous winning area A. It will be determined from the number of balls.

As a condition for returning the opening / closing blade 27 to the initial state, the number of continuous winning balls (the number of times the continuous winning switch 80 is turned on) is increased within a range in which the ratio of continuous winning to general winning can be kept within the standard. Is also good.

[0083]

In summary, according to the present invention, it is difficult or unacceptable to receive a game ball in the winning area.
In a variable winning device of a pachinko machine that includes a movable member that can be converted into a second state that is easy to accept, a surface area that is likely to violently collide with a game ball is a metal as a mounting board to a game board surface that constitutes a surface portion of the entire device. Since it is formed of a plated member, it is possible to effectively prevent partial premature wear and damage due to the collision of balls, and thus obtain good durability of the entire substrate.

When the metal plated member is formed in a frame shape that covers the entire surface area of the game ball, which includes the outer edge portion of the substrate and the entrance portion of the winning area, which is likely to collide with vigorously,
Since this forms a sturdy skeleton of the outer shape of the substrate, it is expected that the rigidity of the entire substrate will be increased.

Further, if the metal plated member is constructed so as to be separable from the constituent members forming the other surface area, not only the plating process of the member becomes easy, but also the parts can be exchanged separately from the other constituent members, which is economical. Benefits are obtained.

Further, by forming the hole for the mounting screw with the game board surface in the frame-shaped metal plating member, it is possible to secure sufficient strength to withstand the tightening of the screw, and it may be chipped due to collision with the game ball. There is no need to do it. If the guide member that supports the movable member of the substrate is also integrally formed of a metal plated member, it is possible to easily secure the abrasion resistance and the like required for the member.
