Description

  The present invention relates to a gaming machine that plays a game by firing a game ball into a game area.

  For example, in a pachinko gaming machine, a gaming board is attached to the gaming machine body, and a gaming area is formed on the board surface of the gaming board. A game ball is launched into the game area based on a launch handle operation by the player. Specifically, when the launch handle is operated, drive power is supplied from the launch control device (launch control circuit) provided on the back of the gaming machine to the game ball launch device, and the game ball is launched.

  In this configuration, in recent years, one using an electromagnetic solenoid as a driving source of a game ball launching device is known (see, for example, Patent Document 1). In this game ball launching device, it is necessary to make the plunger protrude at a high speed and at a high speed. Therefore, it is necessary to momentarily apply a large current to the solenoid coil. Therefore, the launch control device is provided with a large-capacity capacitor element.

  Various devices including the launch control device are supplied with power from a power supply device (power supply circuit) provided on the back of the gaming machine. In this case, while AC power is supplied from the commercial power source to the power supply device, it is necessary to supply DC power to the launch control device and the like. Therefore, a smoothing capacitor element is provided in the power supply device, and a capacitor having a large capacity is used to increase the smoothing effect.

In the gaming machine having the above-described configuration, the game board affects the game performance, so the design needs to be changed for each model of the gaming machine. On the other hand, by installing a launch control device and a power supply device that do not affect game playability to the main body of the gaming machine, and making these designs not change for each model of the gaming machine, the members constituting the gaming machine Reusability is improved, and the efficiency of member management is improved.
JP 2004-230009 A

  Here, if the game area can be expanded, it is considered that a significant difference can be given to other similar game machines and uniqueness as a game machine can be added. However, in order to expand the game area, the game board must be expanded, and accordingly, the area for attaching the game board in the gaming machine body (game board attachment area) must also be expanded. In such a case, as described above, a launch control device and a power supply device are attached to the gaming machine main body, and it is difficult to expand the game board attachment region with the conventional configuration. Further, the game board mounting area can be expanded by enlarging the gaming machine main body, but in this case, the gaming machine cannot be installed in existing gaming machine installation facilities such as a gaming hall.

  The present invention has been made in view of the above circumstances, and in a gaming machine in which a launch control circuit and a power supply circuit are provided in the gaming machine body, it is possible to suitably realize expansion of the game board mounting area in the gaming machine body. It is an object to provide a game machine that can be used.

  Hereinafter, effective means for solving the above-described problems will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

Means 1. A game board (game board 30) provided at a position visible from the front of the game machine, and a game machine main body (main body frame 12) to which the game board is attached, and a rail for guiding a game ball to the front of the game board ( In a gaming machine that is partitioned by a rail unit 50) and in which a game area in which game balls guided by the rail flow down is formed,
A game ball launching device (solenoid 162) that converts the drive power supplied to linear displacement of the collision part (collision member 162d) and launches a game ball into the game area via the rail by the displacement of the collision part; ,
A firing control circuit (a firing control circuit E1) that is provided with a first capacitor element (capacitor Q1) and supplies a power source charged in the first capacitor element when the predetermined condition is satisfied as the driving power source;
A smoothing second capacitor element (capacitor Q2); a power supply circuit (power supply circuit E2) for generating a DC power supply from an AC power supply supplied from an external power supply and supplying the DC power supply to the launch control circuit; Prepared,
These launch control circuit and power supply circuit are surrounded by a single circuit enclosing box (substrate box 316) to form a launch control and power supply device (launch control and power supply device 313).
A gaming machine comprising the launch control and power supply device mounted on the back of the gaming machine main body.

  In the means 1, the game board is provided at a position where it can be visually recognized from the front of the game machine, and the game area is formed inside the section of the front face of the game board by the rail. Then, the game ball launched from the game ball launcher is guided to the game area by the rail and flows down the game area.

  The game ball launching device converts the supplied driving power into a linear displacement of the collision portion, and launches a game ball by the displacement of the collision portion. In this case, in order to launch the game ball into the game area, it is necessary to displace the collision part with high force and high speed, and therefore it is necessary to instantaneously supply a large power to the game ball launching device. Therefore, a large-capacity first capacitor element is provided in a launch control circuit that supplies driving power to the game ball launcher. This is because by charging the first capacitor element with a power source and discharging it in a short time, a large power source can be instantaneously applied to the game ball launching device.

  The first capacitor element is charged by a DC power supply supplied from a power supply circuit. In such a case, the power supply circuit needs to generate a DC power supply from an AC power supply supplied by an external power supply, and the generated DC power supply is smoothed by a second capacitor element provided in the power supply circuit. In order to increase the smoothing effect, the second capacitor element has a large capacity.

  In the above configuration, the launch control circuit and the power supply circuit are surrounded by a single circuit enclosing box to form a launch control / power supply device, and the launch control / power supply device is mounted on the back of the gaming machine body. As a result, the area for mounting the launch control circuit and the power supply circuit on the back of the gaming machine body can be reduced, and the gaming board mounting area in the gaming machine body can be expanded accordingly.

  Here, for example, a configuration in which the launch control circuit and the power supply circuit are surrounded by separate circuit enclosing boxes to form the launch control device and the power supply device, and these are mounted on the back of the gaming machine main body is conceivable. In this configuration, by arranging the launch control device and the power supply device so as to overlap with each other in the gaming machine thickness direction, it is possible to narrow an area for mounting the launch control circuit and the power supply circuit in the gaming machine body. However, as described above, the launch control circuit and the power supply circuit are each provided with a large-capacity capacitor element, and the large-capacity capacitor element is large and relatively tall. Therefore, when the launch control device and the power supply device are arranged to overlap, the dimension in the thickness direction of the gaming machine becomes larger than that of the conventional gaming machine. In this case, for example, it is difficult to install a gaming machine in an existing gaming machine installation facility such as a gaming hall, which is not preferable. On the other hand, according to the configuration of the present means, the above effect can be obtained without causing such inconvenience.

  Mean 2. The gaming machine according to claim 1, wherein the launch control circuit and the power supply circuit are provided on one board (launch control and power supply board 313a).

  According to the means 2, since the launch control circuit and the power supply circuit are provided on the same substrate, the launch control / power supply apparatus can be miniaturized. This makes it possible to further narrow the area for mounting the launch control circuit and the power supply circuit on the back surface of the gaming machine body, and accordingly, it is possible to further expand the game board mounting area in the gaming machine body. Further, with such a configuration, connection parts for connecting the launch control circuit and the power supply circuit become unnecessary, and the number of parts can be reduced.

  Means 3. In the means 1 or 2, the game ball launching device includes a plunger (plunger 162c) provided with the collision portion at a tip, an electromagnetic solenoid body (solenoid body 162b) for driving the plunger, Urging means (returning spring 162e) for urging the plunger to the non-operating position, and the plunger is displaced in a linear direction by the excitation of the solenoid, and the displaced plunger is not operated by the urging force of the urging means. A gaming machine characterized by returning to a position.

  According to the means 3, when the electromagnetic solenoid is energized and excited by the drive power supplied from the launch control circuit, the plunger is displaced in the linear direction. Then, the collision ball provided at the tip of the plunger collides with the game ball, so that the game ball is launched into the game area. Further, the displaced plunger returns to the non-operating position by the urging force of the urging means. In this configuration, since it is necessary to displace the plunger strongly and at high speed against the urging force of the urging means, it is necessary to momentarily apply a large power source to the electromagnetic solenoid. Therefore, the first capacitor element needs to have a large capacity.

Means 4. In any one of the means 1 to 3, a DC power is supplied from the power supply circuit, and a main control circuit (main control board 271a) for controlling the progress of the game, and a DC power supplied by the power supply circuit is below a predetermined power supply. A power supply monitoring circuit (power supply monitoring board 271b) for determining whether or not
A gaming machine, wherein the main control circuit stops the progress of a game based on a determination result of the power supply monitoring circuit.

  According to the means 4, when the power supply monitoring circuit determines that the DC power supplied from the power supply circuit has become equal to or lower than the predetermined power supply, the main control circuit stops the progress of the game. In such a configuration, if smoothing of the DC power supply in the power supply circuit is not sufficient, the DC power supply may instantaneously fall below the predetermined power supply, and the power supply monitoring circuit may be in spite of no power failure occurring in the external power supply. May cause a power outage. Therefore, since it is necessary to perform smoothing sufficiently, the second capacitor element needs to have a large capacity.

  Means 5. A gaming machine according to any one of means 1 to means 4, wherein a plurality of heat radiation holes (heat radiation holes 316a) are formed in the circuit enclosing box.

  Since both the capacitor elements provided in the launch control circuit and the power supply circuit have a large capacity as described above, the heat generation amount increases accordingly. On the other hand, according to the means 5, since a large number of heat radiation holes are formed in the circuit enclosing box, the heat generated from both capacitor elements can be surely released to the outside.

  Here, for example, instead of enclosing the launch control circuit and the power supply circuit with one circuit enclosing box, one circuit enclosing one of both circuits and a circuit for performing control related to the provision of a gaming privilege A configuration in which the box is surrounded by a box is conceivable. However, if a large number of heat radiating holes are formed in the circuit enclosing box in this configuration, it is possible to perform fraud relatively easily with respect to the latter circuit by inserting lead wires or the like from the holes. Further, in order to suppress the fraud, it is necessary to provide a shielding wall or the like for preventing lead wires from entering the inner wall of the circuit enclosure box. On the other hand, by surrounding the launch control circuit and the power supply circuit, which are not directly related to the provision of benefits, with a single circuit enclosing box, there is a risk that fraud will be performed even if a large number of heat radiation holes are formed in the box. There is no need to complicate the structure of the circuit enclosing box.

Means 6. In any one of the means 1 to 5, a payout device (payout device 358) for paying out game balls by the operation of the payout motor (payout motor 358a);
A payout control device in which a DC power supply is supplied from the power supply circuit to control the payout device, and a payout control circuit (payout control board 311a) is surrounded by a circuit enclosing box (board box 315) different from the circuit enclosing box. (Dispensing control device 311),
The dispensing control device is connected to the firing control and power supply device so that the surface direction of the substrate on which the firing control circuit and the power supply circuit are provided and the surface direction of the substrate on which the dispensing control circuit is provided are substantially parallel. United by overlapping,
A game in which the unit (second control board unit 202) is mounted on the back of the gaming machine main body so that the surface direction of the two boards is substantially parallel to the surface direction of the back of the gaming machine main body. Machine.

  In the means 6, the payout motor operates by being controlled by the payout control circuit, and the game ball is paid out from the payout device. In this case, since the payout control device (payout control circuit) does not affect the game playability, it is preferably mounted on the gaming machine main body.

  In this configuration, since both devices are unitized by placing the payout control device over the launch control and power supply device, in order to mount the payout control device in the gaming machine main body in the conventional gaming machine The allocated mounting area can be omitted. Thereby, the game board attachment area | region in a game machine main body can be expanded more.

  In this case, the unit is formed so that the surface direction of the substrate on which the launch control circuit and the power supply circuit are provided and the surface direction of the substrate on which the payout control circuit is provided are substantially parallel. Are mounted on the back surface of the gaming machine body so that the surface directions of both boards are substantially parallel to the surface direction of the back surface of the gaming machine body. For example, in the configuration in which the payout control device is placed so as to overlap the launch control and power supply device so that the board surfaces of both boards are on the same surface, the thickness direction dimension of the gaming machine may become extremely large. By unitizing like this, the thickness direction dimension of the gaming machine does not become extremely large.

  Furthermore, since it is not necessary to momentarily supply a large power to the payout motor, it is not necessary to provide a large capacity capacitor element for driving the payout motor in the payout control circuit. Further, since DC power is supplied from the power supply circuit, it is not necessary to provide a large capacity capacitor element for smoothing in the payout control circuit. In other words, the payout control circuit does not include an element that is taller than both capacitor elements provided in the launch control circuit and the power supply circuit. Therefore, the height dimension of the payout control device is smaller than that of the launch control and power supply device, and even if the payout control device and the launch control and power supply device are arranged in an overlapping manner, the thickness direction dimension of the gaming machine is extremely large. Absent.

  Mean 7 A gaming machine according to claim 6, wherein the launch control and power supply device is disposed on the gaming machine body side, and the payout control device is disposed on the launch control and power supply device.

  As described above, the payout control device does not include a tall element, and is lighter in weight than a launch control and power supply device including a relatively large capacitor element. In this case, according to the means 7, the launch control / power supply device is disposed on the gaming machine main body side, and the payout control device is disposed on the launch control / power supply device. In the configuration in which the devices are stacked, these can be fixed to the gaming machine body in a stable state.

  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter referred to as “pachinko machine”), which is a type of gaming machine, will be described in detail with reference to the drawings. 1 is a front view of the pachinko machine 10, FIG. 2 is a perspective view showing an exploded or exploded main configuration of the pachinko machine 10, and FIG. 3 is a front view showing a front structure of a main body frame 12 constituting the pachinko machine 10. is there. 2 and 3, the configuration in the game area of the pachinko machine 10 is left blank for convenience.

  As shown in FIGS. 1 to 3, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10. The outer frame 11 is attached to a so-called island facility when installed in the game hall. The outer frame 11 is in a state in which wooden plate members are combined in a rectangular frame shape as a whole, and is configured by fixing each plate member with a detachable fastening member such as a small screw. Therefore, compared to the conventional structure in which the plate members are assembled using nails and rivets, the components can be easily reused. In addition, you may comprise the outer frame 11 with metals, such as a synthetic resin and aluminum.

  A body frame 12 is supported at one side of the outer frame 11 so as to be openable and closable. The opening / closing axis is set to extend vertically to the left as viewed from the front of the pachinko machine 10, and the main body frame 12 can be opened forward with the opening / closing axis serving as the axis. Furthermore, since the pachinko machine 10 is provided with a game ball launching handle 18 on the right side, the main body frame 12 can be opened and closed around the side opposite to the game ball launching handle 18. It can be said. The main body frame 12 is made of synthetic resin, specifically ABS resin. By using the ABS resin, the main body frame 12 having a relatively low cost and high impact resistance can be obtained. The body frame 12 may be made of a metal such as aluminum. In the present embodiment, the outer frame 11 and the main body frame 12 constitute a gaming machine main body. As an alternative to the outer frame 11, an installation frame may be provided in advance on the game hall side, and the main body frame 12 may be assembled to the installation frame when the pachinko machine 10 is installed in the game hall. In such a configuration, the main body frame 12 constitutes a gaming machine main body.

  A front plate 14 is provided at a lower position on the front side of the main body frame 12. The front plate 14 is formed in a horizontally long shape, and the width thereof is configured to substantially coincide with the width of the main body frame 12. The front plate 14 includes a base portion 15 having a bulging portion 15a that bulges to the near side in a substantially central portion in the width direction, and a ball tray that is provided inside the bulging portion 15a of the base portion 15 and has a dish shape that is recessed downward. And a back wall panel 17 that forms a wall surface on the back side of the bottom plate 16 and in which a ball discharge port 17a to the bottom plate 16 is formed. Since the base portion 15 is fixed to the main body frame 12 by a fastening member such as a screw, the base portion 15 constitutes an attachment portion for the main body frame 12. A game ball launching handle 18 is provided on the base portion 15 so as to protrude to the right side of the bulging portion 15a.

  The game ball launch handle 18 includes an operation handle 18a and a support base 18b. The operation handle 18a is formed of ABS resin, and the surface thereof is plated. Since the support pedestal 18b is a well-known configuration, a description thereof is omitted, but a touch sensor for detecting that the player is touching the operation handle 18a and detecting that the operation handle 18a is operated are detected. A dial variable resistor for detecting the amount of operation of the firing switch and the operation handle 18a is provided. Furthermore, a stop switch is provided that is operated to stop the launch of the game ball in a state where the operation handle 18a is operated. The signal lines of the touch sensor, firing switch, dial variable resistor, and stop switch are connected to launch control and power supply device 313 described later.

  A slide-type ball removal lever 19 is provided on the front side of the bulging portion 15 a of the base portion 15. The ball removal lever 19 may be a push type. When the ball removal lever 19 is operated, a closing plate (not shown) provided on the bottom surface of the lower plate 16 moves integrally or via a link to open the ball removal hole, and the stored balls in the lower plate 16 are moved. It is configured to be discharged downward. The ball removal lever 19 is provided with a biasing member such as a coil spring that biases the ball removal lever 19 toward the side where the ball removal hole is closed, and the biasing force of the biasing member when the operation of the ball removal lever 19 is released. Thus, the closing plate returns to the open position of the ball hole. A speaker cover portion 17b in which a large number of small holes are gathered is formed at a position different from the ball outlet 17a of the back wall panel 17, and the output sound of the speaker 20 installed behind the panel 17 is the speaker cover. It is emitted forward through the part 17b. The base portion 15 is provided with an ashtray 21 on the left side of the bulging portion 15a.

  Most of the front plate 14 is formed of ABS resin in the same manner as the main body frame 12. The front plate 14 is exposed on the front side of the pachinko machine 10, but by molding with ABS resin, it is possible to apply plating to appropriate portions of the surface for the purpose of decoration or the like.

  A front door frame 13 as a front door is provided in a range excluding the front plate 14 on the front side of the main body frame 12 so as to cover the main body frame 12. Accordingly, the entire front side of the main body frame 12 is covered by the front plate 14 and the front door frame 13. The front door frame 13 is attached to the main body frame 12 so as to be openable and closable. Like the main body frame 12, the front door frame 13 can be opened forward with an opening / closing axis extending vertically to the left when viewed from the front of the pachinko machine 10. It is like that. The front door frame 13 is formed of ABS resin, like the front plate 14. The front door frame 13 is exposed on the front side of the pachinko machine 10, but by molding it with ABS resin, it is possible to plate appropriate portions of the surface for the purpose of decoration or the like.

  A lower portion of the front door frame 13 is provided with a bulging portion 22 that bulges to the near side above the lower plate 16, and an upper plate 23 that opens upward is provided inside the bulging portion 22. . The upper plate 23 is a ball receiving tray for temporarily storing game balls paid out from a payout device described later and guiding them to a game ball launching mechanism 160 described later while aligning them in a line. A ball removal lever 24 for the upper plate 23 is provided on the front surface side of the bulging portion 22, and when this ball removal lever 24 is operated, a ball removal passage (not shown) provided near the most downstream portion of the upper plate 23. Is opened, and the stored balls in the upper plate 23 are discharged to the lower plate 16. In addition, the upper plate 23 can also be comprised with a flame-retardant ABS resin similarly to the lower plate 16 grade | etc.,.

  In the pachinko machine 10, a glass door frame and a front decoration frame are individually provided, and these can be opened and closed with respect to the front frame (corresponding to the main body frame of the present embodiment), and an upper plate is provided on the front decoration frame. Unlike the conventional configuration, the glass door frame and the front decoration frame are integrated into a front door frame 13, and the upper plate 23 is provided integrally with the front door frame 13. In this case, since the glass door frame and the front decoration frame are integrated into the front door frame 13, the strength of the glass support structure can be improved in the front door frame 13. That is, in this pachinko machine 10, for the purpose of expanding the game area, a large glass 137 is mounted on the front door frame 13 along with the expansion of the game area. Therefore, although the frame portion around the glass becomes narrow and there is a concern about the problem of strength reduction, sufficient strength of the glass support structure can be ensured by providing a frame portion integrated with the upper plate below the glass. The front door frame 13 is extended downward so as not to interfere with the game ball launching handle 18 at least when opening and closing the front door frame 13.

  As shown in FIG. 3, the main body frame 12 is mainly composed of a resin base 25 whose outer shape is substantially the same as that of the outer frame 11. A substantially circular window hole 26 is formed at the center of the resin base 25. Is formed. A game board 30 is detachably mounted on the rear side of the resin base 25. As shown in FIG. 4, the game board 30 is made of a substantially square plywood, and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 25. That is, the game board 30 is attached from the rear of the pachinko machine 10, and only the substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the main body frame 12 through the window hole 26 of the resin base 25.

  Next, the structure of the game board 30 is demonstrated based on FIG. The game board 30 is formed with a plurality of large and small openings penetrating in the front-rear direction by being subjected to router processing. Each opening is provided with a general winning port 31, a variable winning device 32, an operating port 33, a through gate 34, a variable display unit 35, and the like. Actually, the general winning port 31, the variable winning device 32, the operating port 33, the through gate 34, and the variable display unit 35 are attached to the surface of the game board by wood screws or the like. In the present embodiment, the variable display unit 35 is disposed substantially at the center of the game board 30, the operation port 33 is disposed below the variable display unit 35, and the variable winning device 32 is disposed further below. In addition, through gates 34 are arranged on both the left and right sides of the variable display unit 35, and a plurality of general winning holes 31 are arranged on both lower sides of the game board 30. The operating port 33 is additionally provided with an electric accessory that is activated (opened) under a predetermined condition. When a game ball enters the general winning port 31, the variable winning device 32, and the operating port 33, it is detected by a detection switch described later, and based on the detection result, the upper plate 23 (in some cases, the lower plate 16) is detected. A predetermined number of prize balls are paid out. In addition, an out port 36 is provided at the bottom of the game board 30, so that game balls that have not entered various winning ports etc. are guided through the out port 36 toward a ball discharge path (not shown). It has become. The out port 36 is formed by cutting out the substantially lower center of the game board 30 in an inverted U shape. Therefore, compared to the conventional configuration in which the out port is formed in a hole shape, the out port can be easily formed (however, in FIG. 4, the rail unit 50 is provided on the front side so that the out port 36 is closed. Is shown). In addition, the game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game ball, and various members such as a windmill 37 are provided.

  On the left and right sides of the game board 30, a plurality of notches 38 are formed as recesses so as to avoid interference with the overhanging regions from the left and right sides of the body frame 12 that is the assembly partner.

  The variable display unit 35 is provided with a symbol display device 41 for variably displaying the first symbol (special symbol) with a winning at the operation port 33 as a trigger. A center frame 43 is disposed in the variable display unit 35 so as to surround the symbol display device 41. The center frame 43 has an upper portion extending forward of the pachinko machine 10. As a result, the game ball is prevented from dropping in front of the display screen of the symbol display device 41, and the inconvenience that the visibility of the display screen is lowered due to the fall of the game ball does not occur. . In the upper center of the center frame 43, a first specific lamp portion 47 and a second specific lamp portion 48 are provided side by side. In addition, a holding lamp 44 corresponding to the first specific lamp section 47 and the symbol display device 41 is provided so as to sandwich the area where both the specific lamp sections 47 and 48 are disposed. The number of times that the game ball has passed through the operating port 33 is held up to a maximum of 4 times, and the holding number is displayed by turning on the holding lamp 44. Note that the hold lamp 44 may be configured to be variably displayed on a part of the symbol display device 41. As described above, since the upper part of the center frame 43 extends forward of the pachinko machine 10, the visibility of the holding lamp 44, the first specific lamp unit 47, and the second specific lamp unit 48 is hindered by the fall of the game ball. It is the composition which is not done. A holding lamp 46 corresponding to the second specific lamp portion 48 is provided below the center frame 43. The number of times that the game ball has passed through the through gate 34 is held up to a maximum of 4 times, and the holding number is displayed by turning on the holding lamp 46. Note that the hold lamp 46 may be configured to be variably displayed on a part of the symbol display device 41, similarly to the hold lamp 44.

  The symbol display device 41 is configured as a liquid crystal display device including an 8-inch size liquid crystal display, and display contents are controlled by a display control device described later. On the symbol display device 41, for example, the first symbols are displayed side by side on the left, middle, and right, and these symbols are variably displayed as they are scrolled up and down. When a predetermined combination of symbols is stopped and displayed on a preset active line, a special gaming state (hereinafter referred to as a jackpot) occurs. This symbol variation display will be described in detail later. In addition, the symbol display device 41 has a display screen according to other types such as a CRT, a dot matrix, a 7-segment display, or the like provided with a liquid crystal display such as a 10-inch or 7-inch other than the 8-inch. It may be configured.

  The first specific lamp portion 47 is provided with a red, green, and blue three-color light emission type LED lamp. Then, the emission color is switched in a predetermined order using a winning at the operation port 33 as a trigger. Specifically, red light is turned on with a winning at the operation port 33 as a trigger, and the emission color is switched to green light when a predetermined time elapses in that state. Then, when the predetermined time elapses with the green light turned on, the emission color is switched to blue light. Thereafter, the emission color is repeatedly switched in the order of red, green, and blue until the emission color switching stop time comes. Accordingly, red, green, and blue are repeatedly displayed in this order on the first specific lamp unit 47. And finally, when red or green is stopped and displayed, a jackpot is generated, and when blue is stopped and displayed, no jackpot is generated. In addition, the type of jackpot is different between the case where the stop is finally displayed in red and the case where the stop is displayed in green finally. Jackpot).

  On the other hand, the second specific lamp portion 48 is provided with a red and green two-color light emitting type LED lamp inside thereof. In the second specific lamp unit 48, the emission color is switched in a predetermined order with the passage of the through gate 34 as a trigger. Specifically, when the game ball passes through the through gate 34, lighting of red light and lighting of green light are alternately performed. Thus, red and green are alternately displayed on the second specific lamp unit 48. And when red is stopped and displayed, it is comprised so that the electrically-driven accessory which accompanies the operating port 33 will be in an open state only for the predetermined time.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is switched to a predetermined open state in which a game ball is easy to win in the case of a big win. More specifically, when the jackpot is generated, the variable winning device 32 is in a predetermined open state, and the game ball is easily won. As an opening mode of the variable prize winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that a winning is made to a continuous prize opening in the variable prize winning device 32. In general, it is assumed that the condition for shifting to a round is satisfied, and the variable prize-winning device 32 is repeatedly opened with a maximum of a plurality of rounds (for example, 15 rounds).

  A rail unit 50 is attached to the game board 30 as a rail member for guiding a game ball launched from a game ball launching mechanism 160 described later to the upper part of the game board 30. The game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product, and more specifically, a fluorine-containing polycarbonate resin is used to reduce frictional resistance. The rail unit 50 includes an inner rail portion 51 and an outer rail portion 52 that are provided in an inner and outer double. The inner rail portion 51 is formed in a substantially annular shape except for about 1/4 of the upper portion, and the outer rail portion 52 surrounds the upper open area of the inner rail portion 51 and is parallel to the left side portion of the inner rail 51. Are formed in a substantially semi-annular shape.

  The inner rail portion 51 is integrally formed with other resin portions, and is provided to stand substantially vertically on the surface of the game board 30. Further, the outer rail portion 52 has a support portion 52a that is integrally formed with other resin portions in the same manner as the inner rail portion 51, and is provided to stand substantially vertically on the surface of the game board 30. A sliding plate 52b is attached to the inner surface of 52a to make the flight of the game ball smoother. The sliding plate 52b is made of a long metal strip made of stainless steel, and is supported by the support portion 52a at a plurality of locations. In such a case, a guide rail is constituted by the inner rail portion 51 and the outer rail portion 52, and a ball guide passage is formed by a portion where these rail portions 51 and 52 face each other with a predetermined interval. In addition, in the site | part which the inner and outer rail parts 51 and 52 oppose, each rail part 51 and 52 is connected by the contact part 53 with the game board 30, and a ball | bowl guide channel | path is formed in the groove shape opened to the near side. Has been.

  In the rail unit 50, a return ball prevention member 54 is attached to a portion (left upper portion in FIG. 4) from which the game ball jumps out of the ball guide passage, and a portion corresponding to the maximum flight portion of the jumped game ball (FIG. 4). In the upper right part), a return rubber 55 is attached. The return ball preventing member 54 prevents a situation in which the game ball once jumped from the ball guide passage to the upper portion of the game board 30 returns to the ball guide passage. In addition, the game ball launched at a predetermined momentum or more hits the return rubber 55 and is rebounded toward the center of the game area.

  An arc-shaped flange 56 projecting outward is formed on the outer periphery of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into the plurality of through holes formed in the flange 56 and the game board is inserted. The rail unit 50 is fastened to 30. Here, the upper and lower and left and right ends of the rail unit 50 are formed in a substantially linear shape. That is, the flanges 56 are cut off at the upper and lower and left and right ends of the rail unit 50 so that the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. It has become. The rail unit 50 is disposed so that the position of the game area on the game board 30 that is the maximum width reaches the left and right end positions of the game board 30. Among the parts corresponding to the ball guide passages of the rail unit 50, particularly with respect to the game ball receiving part, the corresponding flange 56 is provided from others in order to firmly attach the rail unit 50 and stabilize the flight of the game ball. There are also many screws (three in this embodiment, two in the other).

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail portion 51 and the outer rail portion 52 so as to close a part of the ball guide passage. The convex portion 57 is formed so as to extend downward from the outer peripheral portion of the inner rail portion 51, and has a function of guiding a foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage 76 (see FIG. 3). Have The lower right corner and the lower left corner of the game board 30 are spaces (Sa, Sb in the figure) for attaching a seal such as a certificate paper or a plate. In order to secure this attachment space, the flange 56 Notches 58a and 58b are formed in the upper and lower portions. By adopting a configuration in which a sticker such as a stamp is directly pasted on the game board 30, it is difficult to improperly paste the stamp or the like.

  In the game board 30, a relay terminal hole 59 penetrating in the front-rear direction is provided in the upper left portion outside the rail unit 50, and through this relay terminal hole 59, a connector for connecting the relay terminal board installed on the back surface of the game board 60 is exposed to the front side of the pachinko machine 10.

  Next, the game area will be described. The board surface of the game board 30 is divided into inner and outer areas by a rail unit 50 (inner and outer rail portions 51 and 52), and an inner area divided into a substantially circular shape is a game area.

  In the present embodiment, the game area is an area of a ball guide passage that is an opposite part of the inner and outer rail parts 51 and 52 among the areas surrounded by the inner rail part 51 and the outer rail part 52 when viewed from the front of the pachinko machine 10. It demonstrates as an area | region which excluded. That is, since the game area does not include the ball guide passage portion, the left limit position toward the game area is specified by the inner rail portion 51 instead of the outer rail portion 52. Further, the right limit position toward the game area is specified by the inner rail portion 51, the lower limit position of the game area is specified by the lower end position of the game board 30 in which the out port 36 is formed, and the upper limit position of the game area. Is specified by the outer rail portion 52.

  In connection with the expansion of the game area, the through gates 34 located on both sides of the variable display unit 35 have a guide mechanism that allows the game balls that have passed through the gate 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 33 and the variable prize-winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning a game ball is suppressed. Further, since the game area is expanded in the left-right direction, even if a relatively large variable display unit 35 is provided at the center of the game area, the through-gate 34, the windmill 37, and a plurality of nails are provided on the left and right sides of the variable display unit 35. (Guide nails such as a triangular nail for guiding the game ball to the center) and other objects can be provided with a margin, and the flow of the game ball in the game areas on the left and right sides of the variable display unit 35 It is not monotonous and you can fully enjoy the behavior of the game ball.

  Returning to the description of FIG. 3, a game ball launching mechanism 160 is attached below the window hole 26 (game board 30) of the resin base 25. As shown in FIG. 5, the game ball launching mechanism 160 includes a metal plate 161 as a base member, and an electromagnetic solenoid 162 and a launch rail 163 are attached to the metal plate 161.

  The solenoid 162 houses a hollow solenoid body 162b as a drive source in a housing 162a. A plunger 162c is provided so as to penetrate the solenoid main body 162b and protrude from both ends of the housing 162a. In this case, the plunger 162c is supported so that linear reciprocation is possible on the axis. Further, a collision member 162d is provided at the tip of the plunger 162c. In addition, it is good also considering the front-end | tip of the plunger 162c as a collision part, without providing the collision member 162d. The plunger 162c is biased to a non-operating position where it does not protrude greatly from the housing 162a by a return spring 162e provided in the housing 162a, and further, a linear reciprocating motion is restricted by a stopper (not shown) so as not to exceed a predetermined range. ing. And when the coil provided in the solenoid body 162b is energized, the plunger 162c moves against the urging force of the return spring 162e.

  The solenoid 162 is arranged so that the plunger 162c protrudes obliquely upward to the left when energized. The firing rail 163 guides the game ball launched by the solenoid 162, and is arranged such that its longitudinal direction extends in the axial direction of the plunger 162c. Note that the game balls B are supplied one by one from the ball exit on the front door frame 13 side (the ball exit leading from the most downstream portion of the upper plate 23) on the launch rail 163. The game balls B are supplied to the launch rail 163. A stopper 164 for holding it on is mounted on the metal plate 161.

  In the above configuration, when the game ball launching handle 18 is operated by the player, when the solenoid 162 is energized, the plunger 162c protrudes and collides with the game ball held by the stopper 164 on the launch rail 163. The game ball is launched by the collision of the member 162d. Then, the game ball moves on the launch rail 163 and is launched into the game area. In this case, it is necessary to move the plunger 162c against at least the urging force of the return spring 162e in order to project the plunger 162c. And it is necessary to project at high speed. Accordingly, a large current must be instantaneously applied to the coil of the solenoid body 162b.

  There is a predetermined gap between the firing rail 163 and the ball guide passage, and a foul ball passage 76 is provided below the gap. Therefore, if the game ball launched from the game ball launching mechanism 160 does not reach the return ball prevention member 54 and returns as a foul ball in the ball guide passage, the foul ball passes through the foul ball passage 76 to the lower plate. 16 is discharged.

  When the foul balls flow backward in the ball guide passage, most of them flow along the outer rail portion 52 and fall downward when reaching the lower end portion of the outer rail portion 52. There is also a rampage in the ball guide path that jumps to the inner rail portion 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 76. Thereby, all of the foul balls are reliably guided to the foul ball passage 76, and interference between the foul balls and the game balls to be fired next is suppressed.

  A pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 163 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distribution unit 245 (see FIG. 10) provided on the back surface of the main body frame 12, and game balls are basically discharged from the first discharge port 66. When the passage leading to the upper plate 23 including the first outlet 66 is filled with game balls, the game balls are discharged from the second outlet 67 instead of the first outlet 66.

  The game ball guide unit 70 is configured to be visible with a transparent resin material such as polycarbonate resin, and between the main body frame 12 and the front door frame 13 with the front door frame 13 closed with respect to the main body frame 12. It is formed so that the thickness is comparatively thin so that it can be accommodated. The game ball guide unit 70 is integrally formed with the foul ball passage 76 described above. The game ball guide unit 70 is formed with a ball discharge passage 71 for communicating the discharge ports 66 and 67 with the lower plate 16. In the game ball guide unit 70, a communication port 72 communicating with the upper plate 23 is formed on the front side of the first discharge port 66 of the main body frame 12, and an opening / closing plate 73 is attached so as to close the communication port 72. ing. The opening / closing plate 73 is rotatably supported by a support shaft 74 and is always urged to a position where the communication port 72 is closed by a spring 75 as urging means.

  According to the above configuration of the game ball guide unit 70, the open / close plate 73 rises as shown in the figure by the urging force of the spring 75 when the front door frame 13 is opened, and the communication port 72 is closed. In this state, the game ball discharged from the first discharge port 66 is guided to the lower plate 16 through the ball discharge passage 71. Therefore, when the front door frame 13 is opened in a state where game balls are stored upstream of the communication port 72, the stored balls flow down to the lower plate 16 through the ball discharge passage 71 without spilling from the communication port 72. To do. That is, even in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 23 is directly provided on the front door frame 13, the game on the upstream side of the communication port 72 when the front door frame 13 is opened. The inconvenience of spilling a ball can be prevented. On the other hand, in the state where the front door frame 13 is closed, the opening / closing plate 73 is pushed open against the biasing force of the spring 75 by the ball passage rod 138 (see FIG. 2) provided on the back surface of the front door frame 13. . In this state, the game ball discharged from the first discharge port 66 is guided to the upper plate 23 through the communication port 72. Accordingly, the game ball upstream of the communication port 72 is paid out to the upper plate 23. A lower plate full tank switch for detecting that the game ball discharged to the lower plate 16 is full (full tank) is attached to the downstream side of the ball discharge passage 71 of the game ball guide unit 70.

  The resin base 25 is provided with a substantially rectangular small window 78 at the lower right portion of the window hole 26. Accordingly, the stamp or the like attached to the space at the lower right corner of the game board 30 (Sa in FIG. 4) can be viewed through the small window 78. It is also possible to directly stick a certificate or the like on the game board 30 from the small window 78.

  A small window 79 is also provided in the resin base 25 at the upper left portion of the window hole 26. The small window 79 is provided in a position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that, and the relay installed on the back of the game board through the relay terminal hole 59 and the small window 79. The connection connector 60 of the terminal board is exposed on the front side of the main body frame 12. In such a configuration, various lamps provided on the front door frame 13 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 12 (resin base 25). A front door frame opening switch 27 for detecting the open state of the front door frame 13 is provided on the top of the resin base 25. The front door frame opening switch 27 has a pin that can be projected and retracted on the front surface of the resin base 25. When the front door frame 13 is opened with respect to the main body frame 12, the pin returns to the protruding position and the opening of the front door frame 13 is detected. When the front door frame 13 is closed with respect to the main body frame 12, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 6) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached to connect the metal fittings to the main body frame 12 side for grounding. Accordingly, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

  A pair of upper and lower support brackets 81 and 82 are attached to the left end side (opening / closing axis line side) of the main body frame 12 as a support mechanism for supporting the front door frame 13 so that it can be opened and closed. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side, and the lower support fitting 82 is provided with a protruding shaft 84 protruding upward. The specific configuration of the front door frame 13 supported by the support fittings 81 and 82 will be described later. Further, a pair of upper and lower metal fittings 155 and 156 (see FIG. 2) provided on the open end side on the back side of the front door frame 13 is inserted into the right end side (opposite to the opening / closing axis) of the main body frame 12. Insertion holes 87 and 88 are provided, respectively. The pachinko machine 10 is configured such that a locking device for locking the main body frame 12 and the front door frame 13 is hidden behind the main body frame 12. Therefore, the front door frame 13 is locked to the main body frame 12 so that it cannot be opened by locking the metal fittings 155 and 156 to the locking device via the insertion holes 87 and 88.

  A cylinder lock 91 as a key member for locking and unlocking the main frame 12 with respect to the outer frame 11 and locking and unlocking the front door frame 13 with respect to the main frame 12 is installed at the lower right corner of the main frame 12.

In this case, the cylinder lock 91 is provided at a position different from the position that is the maximum width of the game area. The cylinder lock 91 has a function to cover both the locking and unlocking of the main body frame 12 and the locking and unlocking of the front door frame 13, and when the key inserted into the key hole is turned counterclockwise (counterclockwise direction) When the key is unlocked and the key is turned to the right (clockwise direction), the front door frame 13 is unlocked.

  As shown in FIG. 2, a vertically long cover member 92 is attached to the main body frame 12 so as to surround the cylinder lock 91. Although detailed illustration is omitted, the cover member 92 has locking portions (hooks) formed at the upper end portion and the lower end portion thereof. Therefore, the cover member 92 is attached to the main body frame 12 by locking the upper locking portion to the main body frame 12 side and sandwiching the lower locking portion between the main body frame 12 and the front plate 14. . The front door frame 13 is formed with a notch 145 corresponding to the shape of the cover member 92. When the front door frame 13 is closed, the cover member 92 together with the front door frame 13 constitutes the front portion of the pachinko machine. . When the front door frame 13 is closed, the flange formed on the cover member 92 is pressed by the front door frame 13 to prevent the cover member 92 from rattling.

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 6 is a rear view of the front door frame 13.

  The front door frame 13 is formed with a window portion 101 as a viewing window so that almost the entire game area can be viewed from the front. The window portion 101 has a substantially oval shape that is nearly circular, and more specifically, a substantially central portion on the left and right sides of the window portion 101 is gently curved as compared to the upper and lower sides. The substantially central portion may have a linear shape.

  Small windows 107 to which a transparent resin is attached are provided on both the left and right sides of the lower end portion of the front door frame 13 so that a part of the surface of the main body frame 12 and the surface of the game board 30 (including a certificate paper) can be visually recognized. The transparent resin attached to the small window 107 is formed in a flat shape so that the inside certificate paper or the like can be easily read by a machine or the like. However, a magnifying lens portion can be provided on the small window 107 so that the hall operator or the like can easily see the internal certificate paper or the like.

  The front door frame 13 is provided with light emitting means such as various lamps around the periphery (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, an annular illumination part 102 incorporating light emitting means such as LEDs is provided symmetrically along the periphery of the window part 101, and an LED or the like is provided at the center of the annular illumination part 102 and at the top of the pachinko machine 10. There is provided a central illumination unit 103 incorporating the light emitting means. In the pachinko machine 10, the central lighting unit 103 functions as a jackpot lamp and notifies that the jackpot is being hit by performing lighting or blinking in the jackpot state. Further, around the upper plate 23, there is also provided an upper plate illumination unit 104 that also incorporates light emitting means such as LEDs. In addition, on the left and right sides of the central illumination unit 103, there are respectively provided a prize ball lamp 105 that is lit during award ball payout and an error display lamp 106 that is lit when a predetermined error occurs. The annular illumination part 102 includes an inner and outer double resin cover layer and a light emitting body (LED) with a launch plate accommodated inside the resin cover layer, and intersects the inner side surface of each resin cover layer vertically and horizontally in each layer. A protrusion (or a wavy protrusion) is provided in the direction of the protrusion. The outer resin cover layer is transparent, and the inner resin cover layer is colored. Therefore, if the annular illumination part 102 is caused to emit light, it is possible to realize the illumination in a state of being dispersed in a large number or in a state accompanied with a stereoscopic effect. A resin material containing glass powder may be used for the resin cover layer. Such a configuration of the resin cover layer can also be applied to other electric decoration parts (for example, the central electric decoration part 103 and the prize ball lamp 105).

  The front door frame 13 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. With a bill or card inserted in a CR unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, the ball lending operation unit 120 confirms the ball lending operation, the card return operation, and the card frequency. be able to. That is, the ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is paid out as long as the remaining amount exists on the card or the like. The return button 122 is operated when requesting the return of a card or the like inserted into the CR unit. The frequency display unit 123 displays remaining amount information such as a card. In addition, in a pachinko machine (so-called cash machine) in which game balls are lent out directly from a ball lending device or the like without using a CR unit, the ball lending operation unit 120 is unnecessary. A decorative sticker or the like is attached to 120 installation portions. Thereby, in the configuration of the present pachinko machine 10 provided with the lending operation unit 120, the pachinko machine using the CR unit (so-called CR machine) and the cash machine can be shared.

  On the back side of the front door frame 13, various metal reinforcing members are provided so as to surround the window portion 101. Specifically, as shown in FIG. 6, reinforcing plates 131, 132, 133, and 134 are attached to the back side of the front door frame 13 and on the left and right and upper and lower outer sides of the window portion 101, respectively. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. Thereby, the closed loop of the electric path by the reinforcing plates 131 to 134 is cut, and the generation of a magnetic field causing noise is prevented.

  As shown in FIG. 6, assembling mechanisms for the main body frame 12 are attached to the reinforcing plate 131 on the opening / closing axis side on the right side of FIG. Then, the mounting brackets 151 and 152 on the front door frame 13 side are attached to the support brackets 81 and 82 (see FIG. 3) on the main body frame 12 side. That is, a shaft hole that opens to the lower surface is formed in the lower mounting bracket 152, and the protruding shaft 84 of the lower support bracket 82 is inserted into the shaft hole, while the upper mounting bracket 151 By inserting the shaft portion into the support hole 83 of the upper support fitting 81, the front door frame 13 is supported to be openable and closable with respect to the main body frame 12. Further, the reinforcing plate 131 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof, and the engaging claw 131a is formed in the hole 12a ( (See FIG. 3). Thereby, even in the pachinko machine 10 in which the front door frame 13 is configured in a form including the upper plate 23 and the upper and lower shaft support intervals thereof are increased, the front door frame 13 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front door frame 13 is suppressed.

  A pair of upper and lower metal fittings 155 and 156 having a hook shape are attached to the reinforcing plate 132 on the opposite side to the opening / closing axis line on the left side of FIG. These metal fittings 155 and 156 extend rearward and are provided so as to correspond to the insertion holes 87 and 88 (see FIG. 3) provided in the main body frame 12. When the front door frame 13 is closed with respect to the main body frame 12, the metal fittings 155 and 156 are inserted into the insertion holes 87 and 88 on the main body frame 12 side, and are locked by the locking device.

  A resin case 136 is attached to the lower reinforcing plate 134 at a position facing the firing rail 163. The resin case 136 accommodates a circuit board for the ball rental operation unit 120. The back surface of the resin case 136 (the surface visible in FIG. 6) is flat, and forms the side wall of the firing rail 163 when the front door frame 13 is closed. Therefore, the game ball is prevented from spilling forward from the launch rail 163.

  A ball passage rod 138 is installed at a part of the lower reinforcing plate 134 cut out toward the back of the pachinko machine 10, and at least above the ball passage rod 138, also at the back of the pachinko machine 10. An eaves portion 139 extending toward the surface is provided. In this case, in a state where the front door frame 13 is closed on the main body frame 12 side, a ridge extending along the upper side of the communication port 72 on the main body frame 12 side enters between the ball passage rod 138 and the collar portion 139. Arranged. Therefore, even if a wire, a film, or the like is invaded from the ball passage rod 138 and an illegal act is attempted, it is very difficult to infiltrate the wire, the film, or the like into the game area. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and the inside of these reinforcing plates 131 to 134 is folded back to form a glass holding groove. The glass holding grooves are formed in two rows on the front and rear sides, and a pair of front and rear glasses 137 having a rectangular shape are held in each glass holding groove. Thereby, the two glass 137 is attached to the front and back at a predetermined interval.

  As described above, in the pachinko machine 10 according to the present embodiment, when the front door frame 13 is closed, a part of the spherical guide passage formed between the inner and outer rail portions 51 and 52 is caused by the front door frame 13. It is configured to be obscured. Therefore, in the ball guide passage, a portion where the opening portion on the near side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching mechanism 160 returns without reaching the return ball prevention member 54, the game ball jumps out of the ball guide passage or the outer rail portion 52 and the glass 137 There is a risk of being caught in a gap formed between them. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers the section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 6 where the rail cover 140 is attached to the front door frame 13), the portion where the ball guide passage protrudes from the side edge portion of the glass 137. A covering portion 141 for covering the surface is provided. With the above-described configuration of the rail cover 140, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage, so that the game ball jumps out of the ball guide passage. In addition, it is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

  Further, on the lower back side of the rail cover 140, a ridge 142 extending in an arc shape along the inner edge and protruding rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 13 is closed. Therefore, for example, even if an attempt is made to cheat by inserting a wire or film from the gap between the front door frame 13 and the main body frame 12, the wire or film is allowed to enter the game area inside the ball guide passage. Becomes very difficult. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented. The protrusion 142 may be formed in a wider range, for example, along the entire area of the inner edge of the rail cover 140. According to such a configuration, it becomes difficult to infiltrate a wire, a film, or the like in a wider range, It is possible to more reliably prevent fraudulent acts that are performed using wires or films.

  Next, the configuration of the first control board unit 201 will be described with reference to FIGS. 14 is a front view of the first control board unit 201, FIG. 15 is a perspective view of the unit 201, FIG. 16 is an exploded perspective view of the unit 201, and FIG. 17 is an exploded perspective view of the unit 201 viewed from the back. .

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 271 and the sound lamp control device 272 are mounted on the mounting base 251. The main control device 271 includes a main control board that controls the main game and a power supply monitoring board that monitors power (for example, monitors changes in voltage). These boards are made of a transparent resin material or the like. It is configured to be accommodated in a substrate box 273 as an encapsulation means. The main control board and the power supply monitoring board are provided with a plurality of connectors, and these connectors are exposed to the outside through openings 273a to 273h formed in the board box 273. And by connecting a harness or a signal line to each connector, electrical connection with other boards (payout control board, board surface relay board 226 etc.) is made. In addition, the main control board is electrically connected to the power supply monitoring board via the connector, but since both the boards are accommodated in one board box 273, the connector for connecting both boards is It is not exposed to the outside. Note that openings are similarly formed in the board boxes of the control devices described below, and the connectors of the boards housed in the board boxes are exposed to the outside through these openings.

  The substrate box 273 includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected so as not to be unsealed by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed. As long as the sealing unit 274 is configured to connect the box base and the box cover so that they cannot be opened, any configuration can be applied. Here, as shown in FIG. 15 and the like, five sealing members are connected. The box base and the box cover are connected so as not to be opened by inserting a locking claw into the long hole of the sealing member. Sealing processing by the sealing unit 274 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation quickly and easily even if unauthorized opening is performed. It is possible to perform the sealing process again even after it has been performed. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 274. When the board box 273 is opened such as when a failure occurs in the housed main control board or power supply monitoring board or when the main control board or power supply monitoring board is inspected, the sealing member into which the locking claw is inserted and the like The connection with the sealing member is cut off. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the substrate box 273 is left in the substrate box 273, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 273.

On the other hand, the substrate box 273 of the main control device 271 is provided with rotationally operable fixtures 277 at two places on the left and right sides of the back surface thereof. When the main controller 271 is mounted on the board mounting surface 252, the main controller 271 is placed so that the fixing tool 277 is inserted into the through hole 256 of the board mounting surface 252, and the fixing tool 277 is placed in this state. The main control device 271 is locked by the turning operation. Accordingly, since the main control device 271 cannot be removed unless the lock 277 is unlocked from the back side of the first control board unit 201, a deterrent effect such as board removal can be obtained.

  In addition, in the mount 251, a shielding part 257 for shielding an opening leading to the back space of the substrate mounting surface 252 is provided below the substrate mounting surface 252 for the main control board. Accordingly, it is possible to prevent a hand or the like from being inserted into the back surface of the mounting base 251 from below the substrate mounting surface 252 so that the locked state of the fixture 277 cannot be illegally released. Further, when the first control board unit 201 is mounted on the back surface of the pachinko machine 10, the upper portion of the unit 201 is covered with the back pack unit 203, so that it is also prevented that a hand or the like is inserted into the back surface of the mounting base 251. The locked state of the fixture 277 cannot be illegally released.

  As described above, the first control board unit 201 cannot be removed unless the back pack unit 203 is opened at a predetermined angle or larger, or the unit 203 is not removed. The back pack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation. That is, if the main body frame 12 cannot be opened, the first control board unit 201 cannot be rotated or removed as a result, and the main controller 271 cannot be removed. Therefore, unauthorized replacement or theft of the main controller 271 can be effectively prevented.

  The main control device 271 is arranged on the near side when viewed from the back of the pachinko machine 10, and the sound lamp control device 272 is arranged on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with steps in the front-rear direction, the control devices 271 and 272 are mounted in a state where the main controller 271 and the sound lamp controller 272 are mounted on the substrate mounting surfaces 252 and 253. Are arranged with part of them stacked one after the other. That is, as can be seen in FIG. 15 and the like, main controller 271 is arranged in a state where a part thereof (about 1/3 in the present embodiment) is floated. Therefore, it is possible to extend the sound lamp control device 272 to a region overlapping with the main control device 271, and, from another viewpoint, it is possible to extend the main control device 271 to a region overlapping with the sound lamp control device 272. Even within the limited size of the pachinko machine 10, it is possible to satisfactorily cope with the increase in size of the control boards 271 and 272, and the control devices 271 and 272 can be installed efficiently. Further, when the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252 so that the variable winning device 32 and its electric wiring can be installed without difficulty. Note that lattice-like ribs 258 are provided on the back surface of the substrate mounting surface 252 to enhance the support strength of the main controller 271.

  A pair of upper and lower retaining pins 261 are provided on the left end surface of the mounting base 251, and the first control board unit 201 rotates with respect to the game board 30 by attaching the retaining pins 261 to the bearing fitting 231. Cantilevered so that it can move. A pair of upper and lower nai latches 262 are provided at the right end of the mounting base 251 as fasteners to be fitted into the fastening holes 232. A long hole 263 in which the locking claw piece 233 is locked is provided at the upper end portion of the mounting base 251. Therefore, the first control board unit 201 is fixed to the game board 30 by fitting the nail latch 262 into the fastening hole 232 and engaging the engaging claw piece 233 in the long hole 263. It should be noted that the bearing fitting 231 and the latch pin 261 are in the support shaft portion M1, the fastened hole 232 and the ny latch 262 are in the fastening portion M2, and the locking claw piece 233 and the long hole 263 are in the locking claw portion M3. Each corresponds.

  Next, the configuration of the second control board unit 202 will be described with reference to FIGS. 18 is a front view of the second control board unit 202, FIG. 19 is a perspective view of the unit 202, and FIG. 20 is an exploded perspective view of the unit 202. FIG. 21 is a sectional view taken along line AA in FIG.

  The second control board unit 202 has a horizontally long mounting base 301 on which the launch control and power supply device 313 is mounted. Specifically, the mounting base 301 is made of a colorless and transparent resin molded product, and a flat substrate mounting surface 302 is provided on the surface thereof. Then, the launch control / power supply board 313a provided on the launch control / power supply device 313 is fired onto the board mounting surface 302 such that the back surface (the surface opposite to the element mounting surface) of the launch control / power supply board 313 and the substrate mounting surface 302 face each other. A control and power supply 313 is mounted. A CR unit connection board 314 is mounted on the board mounting surface 302 of the mount 301 in a state of being side by side with the launch control and power supply device 313.

  The mounting base 301 is provided with a pair of upper and lower retaining pins 305 at the right end when viewed from the rear of the pachinko machine 10, and the second control board unit is inserted into the bearing portion 237 from above. 202 is cantilevered so as to be rotatable with respect to the main body frame 12. A pair of upper and lower nail latches 306 are provided as fasteners at the left end of the mounting base 301, and the second control board unit 202 is fixed to the main body frame 12 by fitting the nail latch 306 into the tightened hole 239. The bearing portion 237 and the latch pin 305 correspond to the support shaft portion M4, and the fastened hole 239 and the ny latch 306 correspond to the fastening portion M5, respectively.

  The CR unit connection board 314 is electrically connected to a ball rental operation unit 120 on the front surface of the pachinko machine and a CR unit (not shown) for inserting a card or the like (storage medium), and mainly receives a command for a ball rental operation by a player. Is output to the payout control device 311. Note that the CR unit connection board 314 is not necessary in a cash machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a CR unit.

  The launch control and power supply device 313 is configured by housing a launch control and power supply substrate 313a in a substrate box 316 made of a colorless and transparent resin molded product (see FIG. 21). The substrate box 316 may have a configuration made of a colored transparent resin molded product as long as the inside can be visually confirmed. The launch control and power supply board 313a controls the launch of the game ball, and further, a predetermined DC power source required by each control device or the like is generated and output. The substrate box 316 is provided with a large number of heat radiation holes 316a arranged in a lattice pattern (see FIG. 19 and the like). The launch control and power supply 313 is provided with a RAM erase switch 323. This pachinko machine 10 has a function to store and store various data. Even if a power failure occurs, the pachinko machine 10 retains the state at the time of the power failure, and returns to the state at the time of the power failure when returning from the power failure (power recovery). You can return. Therefore, for example, when the power supply is turned off in the normal procedure as in the case of the game hall being closed, the state before the turn-off is stored and held. However, if the power is turned on while pressing the RAM erase switch 323, the RAM data is initialized. It is like that.

  A pedestal plate 303 made of a colorless and transparent resin molded product is fixed on the board box 316 of the launch control and power supply device 313. The pedestal plate 303 may be formed of a colored transparent resin molded product. The base plate 303 has a substantially flat plate shape, and a flat substrate mounting surface 303a is provided on the surface thereof. A payout control device 311 is mounted on the substrate mounting surface 303a.

  The payout control device 311 accommodates a payout control board 311a for controlling the payout of prize balls and lending balls in a board box 315 made of a colorless and transparent resin molded product (see FIG. 21). The substrate box 315 may be formed of a colored and transparent resin molded product as long as the inside can be visually confirmed. The back surface (the surface opposite to the element mounting surface) of the payout control substrate 311a faces the substrate mounting surface 303a of the base plate 303. Further, the payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball clogging of a payout motor, which will be described later, the payout motor is rotated forward and reverse so that the ball clogging is eliminated (return to the normal state). It has become. Since a base plate 303 is interposed between the payout control device 311 and the launch control and power supply device 313, for example, a metal plate or the like may be attached to the base plate 303 in order to install a metal plate or the like for noise removal. Noise countermeasures can be easily realized.

  Here, as shown in FIG. 21, a plurality of capacitors Q1, Q2 are mounted on the element mounting surface of the launch control and power supply board 313a (note that some capacitors Q1, Q2 are shown in FIG. 21). . The capacitor Q1 is provided on the launch control circuit E1 for controlling the launch of the game ball, and the solenoid 162 that is the drive source of the game ball launch mechanism 160 is energized by the discharge from the capacitor Q1. As described above, since a large current (power supply) must be instantaneously applied to the solenoid 162, the capacitor Q1 needs to have a large capacity, and the capacitor Q1 is relatively large and tall (L1). (Capacity is 4700 μF at 50V, for example).

  On the other hand, the capacitor Q2 is provided on a power supply circuit E2 for generating a DC power source from an AC power source supplied from a commercial power source (external power source) and outputting the DC power source to each control device or the like. When generated, the DC power supply is smoothed by the capacitor Q2. In order to increase the smoothing effect, it is necessary to use a large-capacity capacitor, and the capacitor Q2 is a relatively large and tall (L1) capacitor (capacity is, for example, 3500 μF at 50V). . Both capacitors Q1 and Q2 have substantially the same height.

  On the other hand, on the element mounting surface of the dispensing control board 311a, no tall capacitors such as the capacitors Q1 and Q2 are mounted, and a capacitor Q3 that is smaller and shorter than the capacitors Q1 and Q2 is mounted. (L2 <L1). Control of the payout motor 358a by the payout control board 311a is performed over a predetermined period, and does not require a momentary large power supply as in the case of controlling the solenoid 162. Further, the direct current supplied from the power circuit E2 This is because a smoothing capacitor is not required to control the dispensing motor 358a based on the power source. And since the said capacitor | condenser Q3 is the tallest element on the payout control board 311a, the thickness dimension of the payout control apparatus 311 is smaller than launch control and the power supply device 313. Therefore, in the configuration in which the payout control device 311 is mounted on the launch control and power supply device 313, the dimension in the thickness direction of the pachinko machine 10 does not become extremely large. The launch control and power supply device 313 is heavier than the payout control device 311, but the launch control and power supply device 313 is mounted on the mounting base 301, and the payout control device 311 is mounted thereon. Thus, these can be attached to the main body frame 12 in a stable state.

  Further, since the substrate boxes 315 and 316 of the control devices 311 and 313 are transparent, the substrates 311a and 313a can be visually inspected and inspected without opening the substrate boxes 315 and 316. Further, as described above, since the payout control device 311 is disposed on the launch control and power supply device 313, the element mounting surface of the payout control board 311a is hidden by the launch control and power supply device 313 when viewed from the back side of the pachinko machine. Not. Therefore, it is possible to visually inspect and inspect the element mounting surface of the payout control board 311a in a state where the payout control device 311 is mounted on the launch control and power supply device 313.

  The board box 316 of the launch control and power supply device 313 has a thickness set in accordance with the height of the capacitors Q1 and Q2. In this case, as described above, since both the capacitors Q1 and Q2 have substantially the same height, the front surface (element mounting surface) of the board box 316 is configured in accordance with the height of both the capacitors Q1 and Q2. The surface facing the surface becomes substantially flat.

  Next, the configuration of the back pack unit 203 will be described with reference to FIGS. 22 is a front view of the back pack unit 203, and FIG. 23 is an exploded perspective view of the back pack unit 203. FIG. 24 is an exploded perspective view of the tank rail.

The protective cover portion 354 has a shape in which the left and right side surfaces and the upper surface are closed and only the lower surface is opened, and has a size sufficient to surround at least the variable display unit 35. However, in this embodiment, the above-described sound lamp control device 272 is also enclosed. A large number of ventilation holes 354 a are provided on the back surface of the protective cover portion 354. The vent holes 354a are each formed in a long hole shape, and are provided so that the respective vent holes 354a are adjacent to each other at relatively close positions. Therefore, the back surface of the back pack 351 can be easily opened by cutting the resin portion between the adjacent vent holes 354a. That is, a predetermined test or the like can be easily performed by cutting the resin portion between the vent holes 354a and exposing the display control device 214 and the like inside thereof.

  On the base portion 353 of the back pack 351, a payout mechanism portion 352 is disposed so as to bypass the protective cover portion 354. That is, a tank 355 opened upward is provided at the uppermost portion of the back pack 351, and game balls supplied from the island facilities of the game hall are sequentially replenished to the tank 355. Below the tank 355, for example, a tank rail 356 having two rows (two rows) of ball passages in the horizontal direction and gently inclined toward the downstream side is connected. The tank rail 356 extends in the vertical direction on the downstream side. A case rail 357 is connected. The payout device 358 is provided in the most downstream portion of the case rail 357, and the payout motor 358a is driven by the control of the payout control device 311 so that a required number of game balls are paid out appropriately. The game balls paid out from the payout device 358 are supplied to the upper plate 23 and the like through the payout passage 359 and the like. Although not shown in the figure, a tank ball absence sensor that detects the presence or absence of a game ball supplied from the tank 355 or the tank rail 356 is provided upstream of the case rail 357. In addition, the payout device 358 is provided with a payout rotation sensor that detects whether or not the payout motor 358a is rotating, and a payout count switch that counts the number of game balls to be paid out.

  A vibrator 360 for attaching vibration to the tank rail 356 is attached to the tank rail 356. Vibrator 360 is unitized by a vibrator motor and a synthetic resin case that accommodates the vibrator motor, and is attached to tank rail 356 by two legs 360a. Therefore, if a clogged ball occurs near the tank rail 356, the clogged ball is eliminated by driving the vibrator 360.

  The structure of the tank rail 356 will be described in detail. As shown in FIG. 24, the tank rail 356 has a rail body 361 having a long bowl shape opened upward. A spherical ball receiving portion 362 is formed in the upstream portion of the rail main body 361 so that the game ball dropped from the tank 355 by the ball receiving portion 362 is smoothly taken into the rail main body 361. The rail body 361 is provided with a partition wall 363 extending in the longitudinal direction, and the game balls are divided into two hands by the partition wall 363. The two ball passages partitioned by the partition wall 363 are slightly wider than the diameter of the game ball. On the bottom surface of each spherical passage partitioned by the partition wall 363, one or two ridges 364 are provided, and an opening 365 for dropping dust is provided on the side of the ridge 364. Yes. The rail body 361 is provided with a rectifying plate 367 so as to cover the ceiling portion of the downstream half. The rectifying plate 367 has a bow shape so as to limit the height of the ball passage in the tank rail 356 toward the downstream side, and a convex portion 368 extending in the longitudinal direction is formed on the lower surface thereof. Thereby, each game ball flowing in the tank rail 356 finally flows out downstream without being stacked up and down. Therefore, even if a large amount of game balls flow into the tank rail 356, the game balls are prevented from being bitten and the ball clogging in the tank rail 356 is difficult to occur. The rail main body 361 is formed of a black conductive polycarbonate resin to prevent electrification, while the rectifying plate 367 is formed of a transparent polycarbonate resin so that a clogging of a ball can be visually confirmed. The rectifying plate 367 is detachably provided. By removing the rectifying plate 367, maintenance in the tank rail 356 can be easily performed. A manual stopper 369 for preventing the game ball from flowing down is attached to the current plate 367.

A main control board 271a is connected to the input side of the display control board 214a via a relay terminal board 276, and based on various commands output from the main control board 271a, an audio lamp control device 272 and a symbol display device are connected. 41 is controlled.

  Here, as described above, the power monitoring board 271b monitors the power source of stable DC 24 volts, which is the maximum power output from the launch control and power board 313a. In such a case, if the power supply becomes less than 22 volts, it is determined that a power failure (power cutoff) has occurred, and a power failure signal is output to the NMI terminal (non-maskable interrupt terminal) provided in the CPU 501 of the main control board 271a. As a result, the main control board 271a recognizes the occurrence of the power failure and immediately executes the NMI interrupt processing, and further executes the power failure processing based on this. Here, as described above, the DC stable 24 volt output from the launch control and power supply board 313a is sufficiently smoothed by the capacitor Q2, so that the DC stable 24 volt is obtained even though no power failure has occurred. It is prevented from instantaneously becoming less than 22 volts.

  Moreover, the main control board 271a outputs a power failure command to the payout control board 311a via the harness HL in the process at the time of a power failure. The payout control board 311a executes a power failure process described later based on the power failure command. In other words, in the present embodiment, the payout control board 311a does not execute the power outage process by inputting the power outage signal from the power monitoring board 271b, but inputs the power outage command from the main control board 271a. Execute.

  It should be noted that the launch control and power supply board 313a has an output of 5 volts, which is a drive power supply for the control system, for a time sufficient to execute the power failure process even after the DC stable 24 volt power supply is less than 22 volts. Is maintained at a normal value. Specifically, the firing control and power supply board 313a is provided with a power failure processing capacitor different from the above-described data storage holding capacitor, and a 5-volt power supply is maintained by the discharge from the capacitor. ing. Therefore, the main control board 271a and the payout control board 311a can normally execute and complete the power failure process.

  Next, the display content of the symbol display device 41 will be described with reference to FIG.

  In the symbol display device 41, three symbol columns of left, middle, and right are set. Each symbol row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-symbol made of, for example, a diamond-shaped picture. Each main symbol and sub symbol constitute the first symbol. In each symbol row, main symbols are arranged in ascending or descending order of numbers, and sub symbols are arranged between the main symbols. That is, each symbol row is provided with a total of 20 first symbols of 10 main symbols and 10 sub symbols. In this case, the main symbols with odd numbers (1, 3, 5, 7, 9) correspond to “high probability symbols”, and when the high probability symbols are aligned, the big game state that is a special gaming state is entered. After that, the state shifts to a state with a high probability. The main symbols with even numbers (2, 4, 6, 8) correspond to “low-probability symbols”. When the low-probability symbols are aligned, the game shifts to a jackpot state. Does not transition to the time state. The high probability means a state where the combination of the first symbol is a big hit by a predetermined combination of probability fluctuation symbols and the subsequent big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state. Moreover, in the 1st specific lamp part 47, red is displayed at the time of the big hit which becomes a probability change state, and green is displayed at the big hit which becomes a normal state.

  On the symbol display device 41, 20 first symbols are variably displayed so as to scroll from top to bottom with periodicity for each symbol row. In particular, the numbers of the main symbols appear in descending order in the left symbol row, and the numbers of the main symbols appear in ascending order in the middle symbol row and the right symbol row. The symbol display device 41 is configured to display the upper, middle, and lower three first symbols for each symbol row. Accordingly, the symbol display device 41 displays a total of nine first symbols of 3 rows × 3 columns. The symbol display device 41 has five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5. Then, the variable display stops in the order of the left symbol row → the right symbol row → the middle symbol row, and at the time of the stop, it is a combination of jackpot symbols on any active line (in this embodiment, the same main symbol combination) If you arrange it, a big hit video will be displayed as a big hit.

  Next, the operation of the pachinko machine 10 configured as described above will be described.

  In the present embodiment, the CPU 501 in the main control device 271 uses various counter information in the game to make a big hit lottery, set the emission color of the first specific lamp unit 47, set the symbol display of the symbol display device 41, etc. Specifically, as shown in FIG. 27, the jackpot random number counter C1 used for the jackpot lottery, the jackpot type counter C2 used for determining the jackpot type, and the symbol display device 41 Reach random number counter C3 used for reach lottery when out-of-range changes, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, and first variation type counter used for variation pattern selection of symbol display device 41 CS1 and a second variation type counter CS2 that determines a period for switching the color displayed on the first specific lamp unit 47 , It is set to be used left column, the middle column and the right column the off each off symbol counters in the left-and right to use the setting symbol CL of, CM, and CR.

  Among these counters, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game ball to the operation port 33 is provided. The values of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 are stored in time series in accordance with the winning history.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in the present embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operating port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the values are “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”.

  The jackpot type counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (ie 49), it returns to 0. In the present embodiment, the jackpot type counter C2 determines whether the probability change state or the normal state is set after the jackpot is completed. In this case, C2 = 25 to 49 corresponds to a jackpot that is in a normal state. The jackpot type counter C2 also determines the symbol combination when the symbol display device 41 stops changing and the position where the symbol combination is stopped. That is, in the present embodiment, there are 5 effective lines in the symbol display device 41, and ten specific symbols (main symbols) are set. Therefore, all patterns are set by 50 counter values. Will be. Then, when C2 = 0 to 24, that is, when the jackpot that is in a probable variation state, the combination of odd-numbered symbols and the position at which the symbol combination is stopped are determined. On the other hand, when C2 = 25 to 49, that is, when the jackpot is in the normal state, the combination of the even-numbered symbols and the position at which the symbol combination is stopped are determined. The jackpot type counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the last stop symbol to stop after the reach has occurred by shifting the last stop symbol by one before and after the reach symbol, and the last stop symbol after the reach has also occurred. “Reach other than front / rear out” and stop “completely out” where no reach occurs, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to the reach other than the front and rear deviation, and C3 = 22 to 238 corresponds to the complete deviation. Reach lottery may be set individually according to the state of the lottery probability of the symbol display device 41, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  The first variation type counter CS1 is configured to increment one by one within a range of 0 to 198, for example, and returns to 0 after reaching the maximum value (that is, 198). Within the range of 0 to 240, 1 is added in order, and after reaching the maximum value (that is, 240), it returns to 0. The first variation type counter CS1 determines the display mode of the symbol display device 41, such as so-called normal reach, super reach, premium reach, etc., the first symbol reach type and other rough symbol variation modes, and the second variation type counter CS2 The switching display time is determined as a period for switching the color displayed on the first specific lamp unit 47. The switching display time corresponds to the symbol variation time of the symbol display device 41. Therefore, by the second variation type counter CS2, the elapsed time (in other words, the number of variation symbols) until the final stop symbol (in the present embodiment) stops after reaching occurs in the symbol display device 41, etc. A detailed design variation mode is also determined. That is, regarding the symbol display device 41, a variety of variation patterns can be easily realized by combining both the variation type counters CS1 and CS2. Both variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of both variation type counters CS1 and CS2 are acquired when switching the color displayed on the first specific lamp unit 47 and when determining the variation pattern at the time of starting the variation of the first symbol by the symbol display device 41.

  The left, middle and right off symbol counters CL, CM, and CR determine the stop symbol of the left row 1st symbol, the middle row 1st symbol, and the right row 1st symbol when the big hit lottery is missed. In each column, any one of the 20 first symbols in total including the main symbol and the sub symbol is displayed, so 20 counter values (0 to 19) are prepared for each. The left, upper, middle, and lower symbols are determined by the out symbol counter CL, the upper, middle, and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The upper, middle and lower symbols are determined.

  In the present embodiment, the value of each counter CL, CM, CR is updated at random by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, 20 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated within the normal process so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach of the RAM 503 front / rear reach symbol buffer, reach other than front / rear out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the time of starting the variation of the first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier, and the complete out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case. Although not shown, the second specific lamp random number counter C4 is used for the lottery of the second specific lamp unit 48. The second symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). The second specific lamp counter C4 is periodically updated (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 of the main control board 271a will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is broadly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and power failure to the NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by signal input. For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 28 shows an NMI interrupt process, which is executed when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power monitoring board 271b to the NMI terminal of the CPU 501, and the CPU 501 interrupts the control being executed and starts the NMI interrupt processing. To do. In the NMI interrupt processing, the power failure flag is set in the power failure flag storage area provided in the RAM 503 in step S101, and this processing is terminated. Thereafter, when it is confirmed that the power failure flag is set in the normal processing described later, the power failure processing is executed. This process will be described later in detail.

  Next, timer interrupt processing executed by the CPU 501 of the main control board 271a, for example, every 2 msec will be described with reference to the flowchart of FIG.

  First, in step S201, signal reading processing from various winning switches and payout control board 311a is executed. That is, the state of various switches connected to the main control board 271a, the signal from the payout control board 311a and the like are read, and the detection information is stored by determining the state of the switch and the signal (however, the RAM erase switch 323). Status and power failure signal). The detection information is saved by setting a flag in a flag storage area corresponding to each detection information set in the RAM 503.

  Thereafter, in step S202, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In subsequent step S203, the big hit random number counter C1, the big hit type counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 49 and 238, respectively). Clear to 0 each. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, the start winning process is executed in step S204, and then the present process is terminated. Here, the start winning process will be described with reference to the flowchart of FIG. First, in step S301, it is determined based on the detection information of the operation port switch 224 whether or not the game ball has won a prize (start prize). If it is determined that the game ball has won the operating port 33, in the subsequent step S302, the number N of the operation holding balls of the first specific lamp unit 47 and the symbol display device 41 is less than the upper limit value (4 in the present embodiment). It is determined whether or not there is. The process proceeds to step S303 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one. In the subsequent step S304, the values of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 updated in step S203 are stored in the first area among the free storage areas of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

  When the game ball wins the operating opening 33 (starting winning), the display of the first symbol on the symbol display device 41 starts accordingly. There is a restriction that a predetermined time (for example, 5 seconds) must elapse before stopping. Therefore, in the start winning process, when the start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S304). Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and the variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time has elapsed). .

  Next, the main process started by reset at the time of power-on is demonstrated using the flowchart of FIG.

  First, in step S401, an initial setting process associated with power-on is executed. Specifically, a wait process is executed, for example, for about 1 second in order to wait for the sub-side control board (such as the payout control board 311a) to become operable. In the subsequent step S402, access to the RAM 503 is permitted.

  Thereafter, in step S403, it is determined whether or not the RAM control switch 323 provided in the launch control and power supply device 313 is turned on. In the subsequent step S404, it is determined whether or not a power failure flag is set in the power failure flag storage area of the RAM 503. Is determined. In step S405, a RAM determination value is calculated. In subsequent step S406, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is a checksum value at a work area address of the RAM 503, for example. It is possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in a hall, the power is turned on while pressing the RAM erase switch 323. Therefore, if the RAM erase switch 323 is pressed, the process proceeds to steps S409 to S411. Similarly, when the information on occurrence of power shut-off is not set, or when an abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to steps S409 to S411.

  In step S409, in order to initialize the payout control board 311a (and the display control board 214a and the like) as the sub-side control board, a payout initialization command (and a display initialization command and the like) is output. In subsequent step S410, the used area of the RAM 503 is cleared to 0, and in step S411, initialization processing of the RAM 503 is executed. Thereafter, interrupt permission is set in step S412, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 is not pressed, the power failure flag is stored in step S407 on the condition that the power failure flag is set and that the RAM judgment value (checksum value, etc.) is normal. Clear the power failure flag stored in the area. Thereafter, in step S408, a power recovery command for returning the sub-side control board (such as the payout control board 311a and the display control board 214a) to the gaming state before the power-off is output. Thereafter, interrupt permission is set in step S412, and the process proceeds to normal processing described later. Thereby, it returns to the state before power-off.

  Next, normal processing will be described using the flowchart of FIG. In this normal process, the main process of the game is executed. As its outline, the processing of steps S501 to S509 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S510 and S511 is executed with the remaining time.

  In normal processing, in step S501, output data such as a command updated in the previous processing is output to each sub-side control board. Specifically, the command set in the command setting process described later is output to the display control board 214a and the payout control board 311a. In addition, a stop symbol command, a variation mode command, and the like are output to the display control board 214a when the symbol display device 41 displays the variation of the first symbol. In addition, after the start of the first symbol variation, one each time in the normal processing in the order of variation mode command → left symbol sequence stop symbol command → middle symbol sequence stop symbol command → right symbol sequence stop symbol command One command every 4 msec). In such a case, if an unnecessary command is stored in the RAM 503, the capacity will be exceeded, so that each command is erased from the RAM 503 at the output timing. Note that a command buffer configured by a ring buffer is set in the RAM 503 of the main control board 271a, and the storage pointer and the output pointer of the buffer with command are appropriately updated, so that the command is set and the command is output. Good.

  Next, in step S502, both the variation type counters CS1 and CS2 are updated. Specifically, both variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when their counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of both variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503. In the subsequent step S503, updating of each outlier symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  In the update process of the out symbol counters CL, CM, CR, it is determined whether or not it is the update timing of any of the left, middle, and right symbol sequences, and the out symbol counters CL, CM, CR of the symbol sequence that has reached the update timing are determined. Update. Each out symbol counter CL, CM, CR is updated one by one in one normal process without duplication, and every time the normal processing is executed three times, one set of out symbol counters CL, CM, CR is obtained. It has been updated. And, when the combination of the updated out symbol counters CL, CM, CR is a combination of outreach symbols that are front / rear out of reach, a combination of reach symbols other than front / rear out of reach, a combination of completely out symbols that do not become reach In some cases, the combination is stored in a corresponding buffer. If the combination of the updated off symbol counters CL, CM, and CR is a combination of jackpot symbols, the update process is terminated as it is.

  After the update process of the off symbol counters CL, CM, CR, command setting processing is executed in step S504. In this command setting process, as shown in FIG. 33, in step S601, it is determined whether or not a payout abnormality flag is set in a payout abnormality flag storage area provided in the RAM 503. The payout abnormality flag is a flag that is set by inputting an abnormality signal from the payout control board 311a. The abnormality signal is output when an abnormality occurs with respect to the payout mechanism unit 352. If the payout abnormality flag is not set, the process proceeds to step S603 as it is. On the other hand, if the payout abnormality flag is set, an error command is set in step S602. The error command is output to the display control board 214a in the above-described external output process, and the display control board 214a thereby controls the audio lamp control device 272 so that the error display lamp 106 blinks in a predetermined manner. When the error command is set, the payout abnormality flag is deleted.

  Thereafter, in step S603, it is determined whether or not a winning flag is set in a winning flag storage area provided in the RAM 503. The winning flag is a flag that is set when a game ball wins any of the general winning opening 31, the variable winning apparatus 32, or the operation opening 33. However, the winning flag is set corresponding to each of the general winning port 31, the variable winning device 32, and the operating port 33. This is because the number of prize balls varies depending on the place where the prize is won. If the winning flag is not set, the process is terminated as it is. On the other hand, when the winning flag is set, a winning ball command corresponding to the type of winning flag is set. The prize ball command is output toward the payout control board 311a by the above-described external output processing. The payout control board 311a controls the payout of game balls based on the prize ball command. Such control will be described later in detail. When the prize ball command is set, the winning flag is cleared.

  After the command setting process, a first specific lamp unit control process for switching the color displayed on the first specific lamp unit 47 is executed in step S505. In the first specific lamp unit control process, jackpot determination, on / off control of a light source switch of an LED lamp disposed in the first specific lamp unit 47, and the like are performed. In the first specific lamp unit control process, the symbol display device 41 also sets the first symbol variation display.

  Specifically, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1, and further determines the type of jackpot based on the value of the jackpot type counter C2 (determines whether or not it is a so-called probabilistic jackpot). . At this time, the type of jackpot symbol in the first symbol and the stop line for the combination of jackpot symbols are also determined and set as a stop symbol command. If it is determined that no jackpot will occur, the combination of outlier symbols in the first symbol is determined based on the value of the reach random number counter C3. In such a case, the combination of symbols updated in the outlier symbol counter updating process and stored in the buffer is set as a stop symbol command. Further, based on the value of the second variation type counter CS2, the color switching display time displayed on the first specific lamp unit 47 and the variation display time of the first symbol are determined. Further, the reach type in the first symbol and its rough symbol variation mode are determined based on the value of the first variation type counter CS1, and set as a variation mode command. Each time the on / off control of the first specific lamp section 47 is started in the first specific lamp section control process, the number N of operation reservation balls is decremented. When the number of operation reservation balls N is 0, the on / off control is performed. Does not start.

  After the first specific lamp unit control process, a special winning opening opening / closing process is executed in step S506. In the big prize opening / closing process, the big prize opening of the variable prize winning device 35 is opened or closed in the case of the big hit state. That is, it is determined whether the big winning opening is opened for each round in the big win state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  Thereafter, in step S507, a second specific lamp unit control process for performing a process of switching the color displayed on the second specific lamp unit 48 is executed. Briefly, on the condition that the game ball has passed through the through gate 34, the value of the second specific lamp counter C4 is acquired and the color switching process displayed on the second specific lamp unit 48 is performed each time. To be implemented. Then, when the lottery of the color displayed by the value of the second specific lamp random number counter C4 is performed and red is selected, the electric accessory attached to the operation port 33 is opened for a predetermined time. Although the description is omitted, the second specific lamp counter C4 is also updated by the timer interrupt process shown in FIG. 29, similarly to the big hit random number counter C1, the big hit type counter C2, and the reach random number counter C3.

  After step S507, a game ball launch control process is executed in step S508. In the game ball launch control process, as shown in FIG. 34, first, the launch counter HC is incremented by 1 in step S701, and in the subsequent step S702, it is determined whether or not the value of the launch counter HC is 150 or more. Determine. In such a case, in the normal process, the game ball launch control process is executed every 4 msec, and a time of 0.6 sec is required while the launch counter HC reaches 0 to 150.

  If the value of the launch counter HC is less than 150 in step S702, this process is terminated as it is. On the other hand, if the value of the firing counter HC is 150 or more, the firing counter HC is cleared to 0 in step S703, and the process proceeds to step S704. In step S704, it is determined whether or not a launch permission flag is set in the launch permission flag storage area of the RAM 503. The launch permission flag is a flag that is set when a launch permission signal is output from the launch control and power supply board 313a. If the launch permission flag is set, a launch control signal is output to the launch control and power supply board 313a in step S705, and if the launch permission flag is not set, a launch control signal is output. This process is finished without. In such a case, the firing control signal may be output on condition that the CR unit is connected without failure. The launch control and power supply board 313a inputs one launch control signal, thereby exciting the launch solenoid 162 once to launch one game ball.

  That is, in the pachinko machine 10, the game ball is fired on condition that the player is operating the game ball launch handle 18. Further, as described above, since the time of 0.6 sec is required while the firing counter HC reaches 0 to 150, basically, the firing control signal is output 100 times per minute, and 100 pieces per minute. Game balls are fired. As described above, the main control board 271a is configured to control the permission for launching the game ball because the main part of the game in the pachinko machine 10 that is the launch of the game ball is under the control of the main control board 271a. To put.

  Returning to the description of the normal process (FIG. 32), after the game ball launch control process, it is determined in step S509 whether or not a power failure flag is set in a power failure flag storage area provided in the RAM 503. If the power failure flag is not set, whether or not the next normal processing execution timing has been reached in step S510, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal processing. Is determined. Then, the random number initial value counter CINI and both variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the execution timing of the next normal processing (steps S511 and S512). That is, in step S511, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In step S512, both variation type counters CS1 and CS2 are updated. Specifically, both variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when their counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of both variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503.

  Here, since the execution time of each process of steps S501 to S509 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the jackpot random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. Both variation type counters CS1 and CS2 can be updated at random.

  On the other hand, if it is determined in step S509 that the power failure flag is set, the power supply is shut off due to the power failure, so the power failure processing from step S513 is executed. That is, in step S513, the generation of each interrupt process is prohibited, and then a power failure command indicating that the power supply is shut off in step S514 is sent to other control boards (such as the payout control board 311a and the display control board 214a). Output. In step S515, the RAM determination value is calculated and stored. After the access to the RAM 503 is prohibited in step S516, the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Even after the power supply is completely shut down, the power for holding data storage of the RAM is supplied from the launch control and power supply board 313a. Therefore, the information stored in the RAM 503 before the power is turned off is left in a predetermined state. It is held within a period (for example, 1 day or 2 days).

  Next, each control process executed by the CPU 511 of the payout control board 311a will be described with reference to the flowcharts of FIGS. The processing of the CPU 511 is roughly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and commands that are output from the main control board 271a. For convenience of explanation, the input interrupt process will be described first, and then the main process and timer interrupt process will be described.

  In the interrupt process at the time of input, as shown in FIG. 35, first, the command output from the main control board 271a is stored in the command buffer 513a of the RAM 513 in step S801, and then the command input provided in the RAM 513 is set in step S802. The command input flag is set in the flag storage area, and this process is terminated. As described above, when a command is stored in the command buffer 513a, the storage pointer is referred to and stored in a predetermined storage area, and the next input command is stored to be stored in the next storage area. The pointer is updated.

  Next, the main process of the payout control board 311a will be described using the flowchart of FIG. This main process is started upon reset at power-on.

  First, in step S901, an initial setting process associated with power-on is executed. Specifically, the interrupt mode is set. In step S902, RAM access is permitted, and an external interrupt vector is set in step S903.

  Thereafter, in step S904, it is determined whether or not a power failure flag is set in the power failure flag storage area of the RAM 513. In step S905, a RAM determination value is calculated. In subsequent step S906, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. It is also possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  When the power failure flag is not set, or when abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 513 (steps S911 to S913). That is, in step S911, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S912, initialization processing of the RAM 513 is executed. In step S913, CPU peripheral devices are initialized.

  On the other hand, when the power failure flag is set and the RAM determination value (checksum value or the like) is normal, processing at power recovery (processing at recovery after power interruption due to power failure) is executed. That is, in step S907, the power failure flag is cleared, and in step S908, a payout permission flag for permitting the payout of prize balls is cleared. In step S909, the CPU peripheral device is initialized. The RAM determination value is, for example, a checksum value at the work area address of the RAM 513.

  After the process of step S909 or step S913, an interrupt is permitted in step S910, and in step S914, it is determined whether or not a power failure flag is set in the power failure flag storage area of the RAM 513, and the power failure flag is set. If not, wait until the power failure flag is set.

  On the other hand, if the power failure flag is set, it means that a power failure has occurred. Therefore, the process of step S915 is executed as a power failure process. In the power failure process, first, in step S915, the generation of each interrupt process is prohibited. Thereafter, the RAM determination value is calculated and stored in step S916, and access to the RAM 513 is prohibited in step S917, and the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Even after the power is completely shut down, the data stored and held in the RAM 513 is supplied from the launch control and power board 313a, so that the information stored in the RAM 513 before the power is shut off is within a predetermined period (for example, 1 or 2 days).

  Next, timer interrupt processing executed by the CPU 511 of the payout control board 311a, for example, every 2 msec will be described with reference to the flowchart of FIG.

  First, in step S1001, command determination processing for determining a command input from the main control board 271a is executed. In this command determination process, as shown in FIG. 38, it is determined in step S1101 whether or not a command input flag is set in the command input flag storage area of the RAM 513. If the command input flag is not set, a new command has not been output from the main control board 271a, so this process is terminated. On the other hand, if the command input flag is set, command read processing is executed in step S1102. In the command read process, the input command is read from the command buffer 513a of the RAM 513, and the command input flag is cleared.

  Thereafter, the type of the read command is discriminated in each processing of step S1103, step S1105, step S1110, and step S1111, and processing corresponding to each command is executed. That is, in step S1103, it is determined whether or not the command is a power failure command. If the command is determined, the power failure flag is set in the power failure flag storage area of the RAM 513 in step S1104, and this processing is terminated. When this power failure flag is set, the power failure process described above is executed.

  In step S1105, it is determined whether the command is a payout initialization command. If the command is the command, initialization of the RAM 513 is instructed from the main control board 271a when the power is turned on. After executing the process of step S1109, the present process is terminated. In step S1106, it is determined whether or not a payout permission flag is set in the payout permission flag storage area provided in the RAM 513. If the flag is not set, the work area of the RAM 513 is set to 0 in step S1107. In step S1108, the initial value of the RAM 513 is set. After that, by setting a payout permission flag in step S1109, payout of prize balls is permitted.

  If the payout permission flag is set in step S1106, the process ends without performing the processes in steps S1107 and S1108. With this configuration, even if the input of the payout initialization command is recognized due to noise or the like even though the RAM erase switch 323 is not pressed, the remaining prize ball is paid out to the player. Can be prevented without being erased.

  In step S1110, it is determined whether or not the command is a power recovery command. If the command is the command, the payout control board 311a returns to the state before the power cut-off due to a power failure, so the payout permission flag is set in step S1109. After setting, this process is terminated. With such a configuration, when a prize ball remains before the power is turned off, the prize ball can be paid out immediately.

  In step S1111, it is determined whether or not the command is a prize ball command. If it is the command, in step S1112, the number of prize balls corresponding to the prize ball command is added to the total number of prize balls, and then in step S1109. The payout permission flag is set and the process is terminated.

  If the command read from the command buffer 513a is not a power failure command, a payout initialization command, a power recovery command, or a prize ball command, the command is recognized as a command caused by noise or the like, and the command buffer 513a This process is ended without performing other processes only by updating the read pointer.

  Returning to the description of the timer interrupt process (FIG. 37), after executing the command determination process, it is determined in step S1002 whether or not the payout permission flag is set. If the payout permission flag is not set, the process is terminated. On the other hand, if the payout permission flag is set, the state return switch 321 is checked in step S1003, and the state return operation is executed when it is determined that the state return operation starts.

  In step S1004, setting of a tank ball absence state or a tank ball absence release state is executed according to a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration. In such a case, an abnormal signal is output to the main control board 271a when setting the tank ball absence state.

  Thereafter, in step S1005, the presence / absence of a state to be notified is determined. If there is a state to be notified, the 7-segment LED provided in the payout control device 311 is notified.

  In steps S1006 to S1008, prize ball payout processing is executed. In this case, if the prize ball is not in a payout disabled state and the total number of prize balls stored in the command determination process in step S1001 is not 0 (both steps S1006 and S1007 are NO), the process proceeds to step S1008 and shown in FIG. The prize ball control process described later is started. If the prize ball is not paid out or the total number of prize balls is 0 (YES in any of steps S1006 and S1007), the process proceeds to the lending and payout process in steps S1009 to S1011.

  In the rental ball payout process, if the rental ball is not in a disabled state and a rental ball payout request is received from the CR unit (NO in step S1009, YES in S1010), the process proceeds to step S1011 and is shown in FIG. The ball rental control process described later is started. Further, if the rental ball cannot be dispensed or a rental ball dispensing request has not been received (YES in step S1009 or NO in step S1010), the subsequent ball removal process is executed.

  In step S1012, the state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In subsequent step S1013, control of vibrator 360 (vibration motor control) is executed on the condition that the ball is clogged. Thereafter, this process is terminated.

  Here, in the prize ball control process shown in FIG. 39, in step S1201, the payout motor 358a is driven to execute the prize ball payout. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1203, where the payout motor 358a is driven to execute a retry process and a stop process of the payout motor 358a, and then the process returns to the timer interrupt process in FIG. Here, an abnormal signal is output to the main control board 271a when the rotation of the payout motor 358a is not normal although the retry processing is executed a predetermined number of times (for example, 3 times).

  If the rotation of the payout motor 358a is normal, the process advances to step S1204 to determine whether or not the game ball is normally counted based on the detection result of the payout count switch. If the game ball count is not normal, the process advances to step S1205 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the timer interrupt process in FIG. Here, an abnormal signal is output to the main control board 271a when the count of the game balls is not normal although the retry process is executed a predetermined number of times (for example, 3 times).

  If the game ball count is normal, the process advances to step S1206 to determine whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, a stop process of the payout motor 358a is executed in step S1207, and then the process returns to the timer interrupt process in FIG.

  In the ball lending control process shown in FIG. 40, in step S1301, the payout motor 358a is driven to execute the lending of the ball. In the subsequent step S1302, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process advances to step S1303 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the timer interrupt process in FIG. Here, an abnormal signal is output to the main control board 271a when the rotation of the payout motor 358a is not normal although the retry processing is executed a predetermined number of times (for example, 3 times).

  On the other hand, if the rotation of the payout motor 358a is normal, the process proceeds to step S1304, and whether or not the game ball is normally counted is determined based on the detection result of the payout count switch. If the game ball count is not normal, the process advances to step S1305 to drive the payout motor 358a to execute the retry process and execute the stop process of the payout motor 358a, and then returns to the timer interrupt process of FIG. Here, an abnormal signal is output to the main control board 271a when the count of the game balls is not normal although the retry process is executed a predetermined number of times (for example, 3 times).

  Further, if the game ball count is normal, the process proceeds to step S1306, where it is determined whether or not the game ball count by the payout count switch has reached a predetermined number of rented balls (25) and the payout is completed. If the payout has been completed, a stop process for the payout motor 358a is executed in step S1307, and then the process returns to the timer interrupt process in FIG.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  The launch control circuit E1 and the power supply circuit E2 are surrounded by a single board box 316 to form a launch control and power supply device 313, which is mounted on the back of the main body frame 12, so that The area for mounting the firing control circuit E1 and the power supply circuit E2 can be reduced. In particular, in the present embodiment, since the launch control circuit E1 and the power supply circuit E2 are provided on one board (launch control and power supply board 313a), the launch control and power supply device 313 can be reduced in size ( The area of the launch control and power supply board 313a can be reduced), and the area for mounting the launch control circuit E1 and the power supply circuit E2 on the back surface of the main body frame 12 can be further reduced. As described above, by narrowing the area for mounting the firing control circuit E1 and the power supply circuit E2, the area for attaching the game board 30 in the main body frame 12 can be expanded. And by extending the game board 30, a game area | region is expanded, a remarkable difference is given with respect to another pachinko machine, and the originality as a pachinko machine can be added. By providing the launch control circuit E1 and the power supply circuit E2 on one substrate, a connector or a signal line for connecting the launch control circuit E1 and the power supply circuit E2 becomes unnecessary, and the number of parts can be reduced.

  Here, for example, the launch control circuit E1 and the power supply circuit E2 are surrounded by separate substrate boxes to form a launch control device and a power supply device, and these are stacked in the thickness direction of the pachinko machine, The area for mounting the launch control circuit E1 and the power supply circuit E2 on the back surface of the main body frame 12 can be reduced. However, the firing control circuit E1 is provided with a relatively tall capacitor Q1 for driving the solenoid, and the power supply circuit E2 is provided with a relatively tall capacitor Q2 for smoothing. Then, the thickness direction dimension of the pachinko machine 10 becomes extremely large as compared with the conventional pachinko machine. If it does so, it will become difficult to install the pachinko machine 10 with respect to existing island facilities, such as a game hall, for example, and is not preferable. That is, in a game hall or the like, island facilities are configured in two rows and one set, and the pachinko machines 10 are arranged in the island facilities in each row so that the back sides face each other. In such a case, if the dimension in the thickness direction of the pachinko machine 10 becomes extremely large, each island facility will be separated from the existing one, or the pachinko machine 10 will protrude greatly forward from the existing island facility. However, in the former, the existing island equipment in the game hall cannot be used, and in the latter, the distance between the player and the front of the pachinko machine is shortened, and if one tries to secure the distance between a pair of island equipment The traffic space for players, etc. provided in is reduced. On the other hand, according to the above-described embodiment, the above-described effect can be obtained without causing such inconvenience.

  Further, there is a configuration in which one of both the circuits E1 and E2 and the circuits provided on the main control board 271a and the payout control board 311a in the above embodiment are surrounded by one board box (provided on one board). Conceivable. However, in this configuration, the tall capacitors Q1 and Q2 are adjacent to the circuit of the main control board 271a and the circuit of the payout control board 311a, so the visibility of these circuits is reduced. Further, it is necessary to increase the thickness of the board box in accordance with the height of the capacitors Q1 and Q2. From this point, the visibility of the circuit of the main control board 271a and the circuit of the payout control board 311a is lowered. Since the main control board 271a and the payout control board 311a are boards that perform profit-related control, it is necessary to make it easy to visually recognize the element mounting surface of the board in a state surrounded by the board box from the viewpoint of preventing fraud. On the other hand, in this structure, since visibility falls as mentioned above, it is not preferable.

  By forming a large number of heat radiation holes 316a in the board box 316, the heat generated from the relatively large capacitors Q1 and Q2 can be surely released to the outside of the board box 316. Here, for example, the launch control circuit E1 and the power supply circuit E2 are not surrounded by one board box (provided on one board), but either one of the two circuits E1, E2 and the main circuit in the above embodiment. A configuration in which the circuit provided on the control board 271a and the payout control board 311a is surrounded by one board box (provided on one board) is conceivable. However, if a large number of heat dissipation holes are formed in the board box in this configuration, it is possible to perform a fraudulent act of illegally attempting to receive a game ball illegally by inserting lead wires or the like from the holes. It becomes possible. Further, in order to suppress the fraud, it is necessary to provide a shielding wall or the like that prevents the lead wire from entering the inner wall of the board box. On the other hand, even if a large number of heat radiation holes 316a are formed in the substrate box 316 by surrounding the launch control circuit E1 and the power supply circuit E2 that are not directly related to the payout of the game ball with one substrate box 316, There is no risk of fraud and there is no need to complicate the configuration of the board box 316.

  In addition, since the payout control device 311 is arranged so as to overlap the launch control and power supply device 313 in the thickness direction of the pachinko machine 10, the payout control device 311 is mounted on the main body frame in the conventional gaming machine. The mounting area allocated to can be omitted. Thereby, the area | region for attaching the game board 30 in the main body frame 12 can be expanded more. The payout control board 311a does not need to be provided with a large-capacitance capacitor, and is not provided with an element that is taller than the capacitors Q1 and Q2 provided in the firing control circuit E1 and the power supply circuit E2. Therefore, the height dimension of the payout control device 311 is smaller than that of the launch control and power supply device 313, and even if the payout control device 311 and the launch control and power supply device 313 are arranged in an overlapping manner, the dimension in the thickness direction of the pachinko machine 10 is extremely large. It will never grow.

  Further, by arranging the payout control device 311 on the back side of the pachinko machine 10 with respect to the launch control and power supply device 313, the relatively heavy launch control and power supply device 313 is placed on the back side of the main body frame 12. In a configuration in which the payout control device 311 and the launch control and power supply device 313 are stacked and mounted, these can be fixed to the pachinko machine 10 in a stable state.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) Instead of providing the launch control circuit E1 and the power supply circuit E2 on one substrate 313, the launch control circuit E1 may be provided on the launch control board, and the power supply circuit E2 may be provided on the power supply board. Even in such a configuration, by accommodating the launch control board and the power supply board in one board box, an area for mounting the launch control circuit and the power supply circuit on the back of the pachinko machine 10 (the back of the main body frame 12) is provided. Accordingly, the area for attaching the game board 30 can be expanded.

  (B) In the above embodiment, the launch control circuit E1 and the power supply circuit E2 are surrounded by one board box. However, other circuits may be surrounded by the board box. For example, a CR unit connection circuit may be provided on the launch control and power supply board 313a in the above embodiment. By setting it as this structure, the area | region for attaching the game board 30 in the main body frame 12 can be expanded rather than the said embodiment.

  (C) A configuration in which the payout control device 311 is not mounted on the launch control and power supply device 313 may be employed. Even in this configuration, since the launch control circuit E1 and the power supply circuit E2 are provided as the launch control and power supply device 313, an area for attaching the game board 30 in the main body frame 12 as compared to the conventional pachinko machine is provided. Can be extended.

  (D) In the above embodiment, the electromagnetic solenoid 162 is provided as the drive unit of the game ball launching mechanism 160. However, a piezoelectric element may be provided instead. However, a large number of piezoelectric elements are stacked in order to obtain a striking force that allows the game ball to reach the game area. In this configuration, when a voltage is applied to each piezoelectric element, each piezoelectric element expands in the stacking direction, and the collision portion is displaced in the linear direction. And when the said collision part collides with a game ball, the said game ball is launched toward a game area. Such a multilayer piezoelectric element requires a relatively large amount of power source in order to obtain the hitting force. Therefore, it is necessary to provide the firing control circuit E1 with a large-capacity and relatively large capacitor as in the above embodiment.

  (E) In the above embodiment, a large number of heat radiating holes 316a are arranged in a grid pattern in the board box 316 of the launch control and power supply device 313. An opening may be provided. With this configuration, the heat in the substrate box 316 can be released more efficiently than in the above embodiment. Further, since only the launch control circuit E1 and the power supply circuit E2 that are not directly related to the game ball payout are provided in the board box 316, even if a relatively large opening is provided, fraudulent acts are not performed. .

  (F) The symbol display device 41 is not provided, and the present invention may be applied to, for example, a pachinko machine equipped with a winning combination. In such a case, if the area for mounting the control device on the back of the pachinko machine can be narrowed, a relatively large prize-winning item can be provided. Further, the present invention may be applied to a pachinko machine provided with both the symbol display device 41 and a winning combination. Further, the present invention may be applied to a pachinko machine provided with a symbol display device having a display screen (for example, 15 inches) larger than that of the above embodiment.
