Description

The present invention relates to a gaming machine that circulates and uses a predetermined number of game balls.
In a game machine having such a circulation path, a game ball that has finished a game by launching a predetermined number of game balls in the game machine into a game area by a launching device, as in a so-called enclosed ball game machine, Is collected and returned to the launcher.

  The gaming machine described in Patent Document 1 is an enclosed ball type gaming machine, in which a predetermined number of gaming balls enclosed in a gaming machine main body are launched into a gaming area of a gaming board by a launching device, and the gaming area is played. The game balls that have passed through are collected by a circulation route and led to the launching device again.

  Patent Document 2 describes a ball game machine that is launched from the upper part of the game machine. This gaming machine has a screw that lifts the game ball to the launching device, and describes a technique that efficiently lifts the game ball when intermittently lifting with the screw.

In the gaming machine having the above-described circulation path, the launching device is arranged at the upper part of the game area, the game balls that have been played are collected below the game area, and the launching device (upper part) is again collected by using the ball lifting device. A structure that circulates to a launching device is advantageous as a gaming machine that utilizes the natural fall of a gaming ball.
In a gaming machine equipped with such a circulation path, a game corresponding to the number of game balls (data on the number of balls held) based on the number of rented balls input from a storage medium such as a card via a payment system or the like. In many cases, it is possible to launch a ball, and when a game ball is fired, data on the number of possessed balls is subtracted in accordance with the number of game balls fired.

  In addition, even if the launched game ball wins a winning opening in the game area and becomes a prize ball, the actual game ball is not paid out, and the number of prize balls is added to the data on the number of balls held . In many cases, when the data on the number of possessed balls becomes “0”, a game ball cannot be launched. Therefore, in a gaming machine having a circulation path (for example, the above-described enclosed ball type gaming machine), the game by the enclosed ball type gaming machine is completely in the data on the rental of game balls, the number of hit balls, the winning balls, etc. Often done as a number. Therefore, it is necessary to accurately detect the game balls that have been fired and manage the number of game balls that have been fired.

[Deformed sphere / magnetic ball discharge unit]
FIG. 40 is a view for explaining the deformed sphere / magnetic sphere discharging unit. FIG. 41 is a diagram illustrating the magnetic ball discharger cover in FIG. FIG. 42 is a plan view of the deformed sphere / magnetic sphere discharge unit. FIG. 43 is a rear view of the deformed sphere / magnetic sphere discharge unit. FIG. 44 is a view for explaining the base plate of the deformed sphere / magnetic sphere discharge unit. FIG. 45 is a diagram for explaining the deformed sphere / magnetic sphere discharge unit separately into a deformed sphere discharge unit and a magnetic sphere discharge unit. FIG. 46 is a diagram for explaining a path through which the deformed sphere and the magnetic sphere are discharged in the deformed sphere / magnetic sphere discharging unit. FIG. 47 is a diagram for explaining a situation where magnetic balls are separated from the circulation path and discharged. FIG. 48 is a diagram for explaining a state where the magnetic sphere has reached the magnetic sphere discharge inclined surface.

  As shown in FIG. 40, the deformed sphere / magnetic sphere discharging unit 20 has a deformed sphere discharging function and a magnetic sphere discharging function. The deformed sphere is a spherical object such as a bearing having a smaller diameter than a regular game ball. The deformed sphere / magnetic sphere discharge unit 20 is a transparent resin molded product, and is disposed in the lower part of the gaming machine body (the deformed sphere / magnetic sphere discharge unit accommodating portion 19). The front side is a front plate (not shown), the rear The side is covered with a rear plate (ball receiving base 201). At the top, as a safe ball that has flowed down to various winning gates (special variable winning device, general winning port, ordinary variable winning device) and won out to various winning ports, and flowed down the safe ball discharge route A collection port 202 for collecting the game balls is provided. The out ball flows into the recovery port 202 through the out port 42 (see FIGS. 3 and 5). The safe ball flows into the collection port 202 through the winning port 41 (see FIG. 5).

  The circulation path in the deformed sphere / magnetic sphere discharge unit 20 communicating with the recovery port 202 is formed by meandering the left and right sides of the deformed sphere / magnetic sphere discharge unit 20 and folded up and down. A detection switch 203, a deformed sphere discharge unit 204, a magnetic sphere discharge unit 205, a spherical path full tank detection switch 206, and a proper sphere detection switch 207 are provided. The game balls that have flowed into the recovery port 202 are moved in a line along the circulation path in the deformed sphere / magnetic ball discharge unit 20 and reach the ball assembly 21 connected to the deformed sphere / magnetic ball discharge unit 20. However, the deformed sphere and the magnetic sphere are separated from the regular game sphere circulation path in the deformed sphere / magnetic sphere discharge unit 20 so as not to move to the sphere collecting portion 21 and are discharged out of the deformed sphere / magnetic sphere discharge unit 20. The

  Next, the movement of the game sphere collected in the collection port 202 in the deformed sphere / magnetic sphere discharge unit 20 will be described in order. The number of game balls collected in the collection port 202 is counted one by one by the collection ball detection switch 203. The game ball that has passed through the recovery ball detection switch 203 reaches the deformed ball discharge unit 204. When the difference in the number of game balls detected by the collected ball detection switch 203 and the shot ball detection means increases, it can be detected that an abnormality has occurred in the gaming machine.

  The deformed sphere discharging unit 204 is fixed to a deformed sphere discharging unit base mounting unit 212 provided on the ball receiving base 201, and the two deformed sphere discharging units 208 are fixed to the deformed sphere discharging unit base 208. It is composed of deformed sphere separation shafts 209 and 210.

  As shown in FIGS. 43 and 44, the deformed sphere discharge portion base mounting portion 212 is a rectangular opening provided in the ball receiving base 201. As shown in FIG. 40, the deformed sphere discharge part base mounting part 212 is provided with an inclination to the sphere receiving base 201 so that the side on the recovery port 202 side becomes higher. As a result, the odd-shaped ball separation shafts 209 and 210 are inclined and can be moved from the upstream side 213 (see FIG. 42) toward the downstream side 214.

  FIG. 45 is a diagram for explaining the deformed sphere / magnetic sphere discharge unit separately into a deformed sphere discharge unit and a magnetic sphere discharge unit. FIG. 45A shows the deformed sphere discharge unit 204. FIG. 45B shows a magnetic ball discharge unit 205.

  The deformed sphere discharging unit 204 uses the difference in diameter between the regular game ball and the illegal sphere to exclude the illegal sphere having a diameter smaller than the regular game ball from the circulation path in the deformed sphere / magnetic ball discharge unit 20. . As shown in FIG. 42, the deformed sphere discharge unit 204 includes two deformed sphere separation shafts 209 and 210 having a circular cross section arranged in parallel from the upstream side to the downstream side of the circulation path. In order to eliminate the deformed sphere, that is, the inferior sphere having a diameter smaller than that of the regular game ball, from the circulation path through which the regular game ball circulates, the gap distance between the two deformed sphere separation shafts 209 and 210 is The deformed sphere separation shaft is narrower than the diameter of the regular game sphere and wider than the diameter of the regular game sphere on the downstream side 214, that is, the distance between the two modified sphere separation shafts 209 and 210 is gradually increased. 209 and 210 are fixed to the deformed sphere discharge portion base 208.

  The game balls that flow down to the deformed ball discharge unit 204 one by one via the collection port 202 and the collected ball detection switch 203 flow down while rolling across the two deformed ball separation shafts 209 and 210. To do. Since the gap distance between the two deformed sphere separation shafts 209 and 210 is narrower than the diameter of the regular game ball on the upstream side, the regular game ball does not fall from between the deformed sphere separation shafts 209 and 210.

  On the other hand, an irregular sphere that is a deformed sphere having a diameter smaller than that of a regular game sphere falls from between the two deformed sphere separation shafts 209 and 210. The dropped deformed sphere is discharged from the deformed sphere discharge port 216 to the outside of the deformed sphere / magnetic sphere discharge unit 20 through the deformed sphere discharge path 215 as shown in FIG. The deformed sphere discharge path 215 is formed by a deformed sphere discharge path forming member 217 attached to the front side of the ball receiving base 201 and below the deformed sphere discharge part base 208. The deformed sphere discharge path forming member 217 is also integrally provided with a communication path 218 that guides a sphere having the same diameter as the regular game ball to the magnetic sphere discharge unit 205.

  A game ball of a normal size rolling down the two deformed sphere separation shafts 209, 210 falls from between the two deformed sphere separation shafts 209, 210 on the downstream side 214, and passes through the communication path 218. Then, it reaches the circulation path 219 formed in the magnetic ball discharge unit 205.

  The magnetic ball discharge unit 205 is fixed to the ball receiving base 201 as shown in FIG. FIG. 45 shows a state in which the magnetic ball discharge unit 205 is removed from the ball receiving base 201. The magnetic ball discharge portion 205 is formed with an inclined surface 220 connected to the communication path 218, and a falling surface 221 that is steeply lowered is connected to the downstream side of the inclined surface 220. A magnetic ball discharge inclined surface 222 is formed. A gap between the discontinuous portions 223 is provided so that the inclined surface 220 and the magnetic ball discharge inclined surface 222 are not continuous. In the magnetic ball discharge unit 205, a magnet is attached to at least one of the front surface, the back surface, or the inside of at least one of the side wall 224 and the ceiling wall 225.

  FIG. 47 shows an example in which a magnet 229 is mounted in the magnet housing space 230 on the back surface of the ceiling wall 225. The magnet housing space 230 is formed as a space having a rectangular cross section disposed along the back side of the ceiling wall 225. The magnet 229 is a plate-like magnet, and is a permanent magnet having one side having an N pole or S pole and the other side having an S pole or N pole. The magnetic force of the magnet is not so strong that the game ball (magnetic ball 232) made of a magnetic material is attracted and the rolling is inhibited, and the magnet flows down the region of the inclined surface 220 and falls from the discontinuous portion 223. It is sufficient that the magnetic ball discharge inclined surface 222 can be reached. The magnet to be attached may be a permanent magnet or an electromagnet.

  The regular game ball 233 flowing from the communication path 218 rolls down the inclined surface 220 and flows down from the inclined surface 220 while rolling on the falling surface 221. The normal non-magnetic game ball 233 falls on the discontinuous portion 223 and reaches the ball assembly portion 21 connected to the deformed ball / magnetic ball discharge unit 20 through the circulation path 219.

  On the other hand, the illegal sphere (magnetic sphere 232) made of a magnetic material is attached to the inner wall surface of the ceiling wall 225 by the attractive force of the magnet 229 accommodated in the magnet accommodation space 230, and passes through the circulation path 219 upstream of the inclined surface 220. It flows down while rolling by the action of gravity from the side to the downstream side. 47, the magnetic sphere 232 reaches the region of the magnetic ball discharge inclined surface 222 as shown in FIG. 48 without falling from the discontinuous portion 223. The illegal sphere made of a magnetic material reaching the region of the magnetic ball discharge inclined surface 222 is discharged to the outside of the magnetic ball discharge port 227 and the deformed sphere / magnetic ball discharge unit 20 through the magnetic ball discharge path 226 (see FIG. 46). ).

  A portion of the ceiling wall 225 on the upper side of the magnetic ball discharge inclined surface 222 is configured as a magnetic force adjusting unit 231. The magnetic force adjusting portion 231 is formed so that the distance between the magnet housing space 230 and the magnetic ball discharge path 226 increases as it goes downstream of the magnetic ball discharge path 226. In FIG. 47, the magnetic ball discharge path 226 has a curved portion, and this curved portion functions as the magnetic force adjusting unit 231. Thereby, the distance between the magnetic sphere 232 and the magnet 229 becomes longer toward the downstream side of the magnetic sphere discharge path 226. As a result, the magnetic force (attraction) of the magnet 229 acting on the magnetic sphere 232 gradually decreases. For this reason, the magnetic sphere 232 that has adhered to the wall surface of the ceiling wall 225 and moved in the downstream direction is separated from the wall surface of the ceiling wall 225 and falls onto the magnetic ball discharge inclined surface 222. Then, it is discharged from the magnetic ball discharge port 227 via the magnetic ball discharge path 226.

  The deformed sphere and the irregular sphere of the magnetic substance are discharged from the deformed sphere discharge port 216 and the magnetic sphere discharge port 227 to the outside of the deformed sphere / magnetic sphere discharge unit 20, respectively (FIG. 46). The deformed sphere or magnetic sphere discharged from the deformed sphere / magnetic sphere discharge unit 20 is collected in the discharge sphere receiving box 234 (see FIGS. 2, 3, and 5). In this way, the irregular sphere / magnetic sphere discharging unit 20 can be used to exclude the illegal sphere composed of the irregular sphere and the magnetic material from the regular game sphere circulation path 219. In the present embodiment, the configuration can be simplified by using gravity to discharge the deformed sphere and the deformed sphere / magnetic sphere discharge unit 20 to the outside. The deformed sphere discharge path 215 is disposed along the side surface of the magnetic sphere discharge portion 205, and the deformed sphere / magnetic sphere discharge unit 20 can be configured in a compact manner.

  In addition, during the game using a gaming machine or when the gaming machine is turned off, a staying state in which a regular gaming ball reaches the discontinuous portion 223 in the circulation path 219 does not occur. A gaming machine is configured. If the discontinuous portion 223 is reached, the number of circulating game balls is excessive, so the discontinuous portion 223 is filled with game balls, and then the game balls flowing down flow down the magnetic ball discharge path 226. There is no problem.

  The deformed sphere / magnetic ball discharging unit 20 can eliminate the irregular balls made of deformed spheres or magnetic bodies from the regular game sphere circulation path 219 without stopping the game, thereby reducing the interest of the player. On the other hand, the employees of the game hall can be called to each gaming machine for processing illegal balls, and the opportunity to deal with the malfunction of the gaming machine can be reduced. Note that the deformed sphere discharge unit 204 and the magnetic sphere discharge unit 205 may be configured separately. That is, when discharging the deformed sphere with other components in the gaming machine, the magnetic ball discharging unit 205 may be configured alone.

And one embodiment of the enclosed game machine of the present invention is arranged on the upper part of the main body frame, a game board in which a game area is defined, a main body frame in which the game board is fitted and accommodated, A ball hitting device for launching a game ball toward the game area, and a game ball launched by the ball hitting device is collected as an encapsulated ball on the back side of the game board, and the illegal ball is eliminated and the ball hitting device is again used. One enclosing sphere arranged and stored in an array passage formed in a part of the circulation path based on the drive of an electrical drive source and a circulation path including deformed sphere / magnetic sphere discharge means for supplying In each of the game control processes, a ball feeder that feeds to the launch position of the hitting ball launcher, a main control board that performs a game control process related to a pachinko game, and bidirectional communication with the main control board are possible. Main control Increase / decrease control of the number of balls based on the prize ball command transmitted from the board and the ball number information of the shot ball launched by the hitting ball launching device, the launch control of the game ball by the hitting ball launching device, and the ball A ball information control board that controls the feeding of the game ball to the launch position by the feeding device, and performs a game by circulating a predetermined number of game balls in a closed manner without paying out the game balls The hitting ball launching apparatus performs a hitting operation based on a driving rail for stopping the game ball at the launch position and an electric driving source, and the game stopped at the launch position. A launching member for launching a ball; and a launching ball confirming unit for detecting a game ball parked at the launching position, wherein the ball information control board performs the launching over a predetermined time. For ball confirmation When a game ball stopped at the launch position is detected, a launch ball detection determination unit that determines that there is a launch ball, and a condition that the launch ball detection determination unit determines that there is a launch ball, A number-of-balls subtracting unit that determines that the game ball stopped at the launch position has been launched when the game ball is not detected by the firing-ball confirmation unit, and decrements the number of possessed balls by 1; Is done.
According to the above-described embodiment, when a game ball stopped at the launch position is detected by the launch ball confirming unit over a predetermined time, a launch ball detection determining unit that determines that there is a launch ball. If the game ball is not detected by the launch ball confirmation unit, the game ball that has been stopped at the launch position is determined to have been fired, provided that the launch ball detection determination unit determines that there is a launch ball. When noise enters the launch ball confirmation means, it is possible to eliminate the wrong ball count of the launch ball due to noise, and to increase the certainty in detection of the launch ball. And magnetic balls can be excluded from the circulation path through which regular game balls circulate.

The same applies to the large pitch ridge member 25c, the same reference numerals are given, and a specific description thereof is omitted, but the pitch of the spiral ridge 25d is large. A portion where the spiral protrusion 25d of the small pitch protrusion member 25b and the spiral protrusion 25d of the large pitch protrusion member 25c are continuous is smoothly continuous although the pitch changes.
The large pitch ridge member 25c is composed of a half body 25cR and a half body 25cL.

The pitch is the interval between the spiral ridges 25d along a straight line. The pitch of the spiral protrusion 25d of the small pitch protrusion member 25b is smaller than the spiral protrusion 25d of the large pitch protrusion member 25c. For example, the pitch of the small pitch ridge member 25b is 25 mm at the lower edge, and the pitch of the large pitch ridge member 25c is 43.2 mm.
The screw shaft 25a is a rotating shaft of the screw 25, and an upper lifting gear 360 (spur gear) (FIG. 54) is fixed to the upper end portion, and a lower lifting gear 362 (spur gear) is fixed to the lower end portion. ing.
Further, the small pitch protrusion member 25b at the lower part of the screw 25 is engaged with the fitting concave part 366a of the fitting member 366 fixed to the lower lifting gear 362 by the lower edge convex part 25m using the concave / convex fitting. Thus, it is driven and rotated integrally with the screw shaft 25a.

  The ball lifting motor 150 is a motor for driving the screw 25, and is attached to the lower surface of the upper gear box 356 in the ball lifting device 22 (FIG. 50).

  The upper gear box 356 is disposed at the upper end of the ball lifting device 22 and houses and pivotally supports the ball lifting motor gear 358, the idle gear 359, and the upper lifting gear 360 (FIGS. 52 and 56). . The ball lifting motor gear 358 is fixed to the drive shaft of the ball lifting motor 150 and meshes with the idle gear 359. The idle gear 359 is a two-stage gear in which an upper gear having a large number of teeth and a lower gear having a small number of teeth on the lower surface thereof are integrated, and is engaged with the ball lifting motor gear 358 by the upper gear, and the lower gear. It meshes with the upper lifting gear 360. These gears are spur gears, and the upper gearbox has a lower vertical dimension. The upper lifting gear 360 is fixed to the upper end of the screw shaft 25a. With these gear configurations, the screw 25 is driven and rotated by the ball lifting motor 150.

  The lower gear box 357 is disposed from the lower end of the ball lifting device 22 to the lower end of the ball assembly portion 21, and houses and pivotally supports the lower lifting gear 362 and the ball feeding rotating body gear 363 (see FIG. 54). The lower lifting gear 362 is fixed to the lower end of the screw shaft 25a and meshes with the ball feeding rotating body gear 363. The gear ratio between the ball feed rotor gear 363 and the lower lift gear 362 is 2: 1. The ball feed rotator 350 is fixed to the shaft 363 a of the ball feed rotator gear 363, and the ball feed rotator 350 is driven to rotate by the ball feed rotator gear 363.

  The ball feed rotating body 350 is arranged corresponding to the ball feed port 275b of the ball feed passage 275 in the ball gathering portion 21, and is a low columnar member, and at the peripheral portion, in this embodiment, at 180 degree intervals. A ball engaging recess 350a for receiving the ball is provided. The ball engaging recess 350a has a depth that accommodates about half of the game ball.

The ball feed inclined portion 351 (FIG. 58) is a member that is formed around the ball feed rotating body 350 and has a slope for lifting the game ball. The range in which the ball feed inclined portion 351 exists is that the ball feed rotary body 350 screws the game ball from the position of the ball feed port 275b which is the ball feed rotary body side exit of the ball feed passage 275 with respect to the rotation direction of the ball feed rotary body 350. This is the range up to the delivery position to 25. The ball feed inclined portion 351 has an arc shape along the outer periphery of the ball feed rotating body 350 from the ball feed port 275b to the delivery position as described above, and is 7 mm (about 5 to 8 mm) upward from the position of the ball feed port 275b. ) It has an inclined surface 351a that rises to a high delivery position, and a top inclined portion 351b that protrudes from the top in the direction of the screw 25 and inclines downward. The width of the inclined surface 351a is 4 mm (about 3 to 5 mm), and the top inclined surface 351b is formed in a range larger than the diameter of the game ball before and after the transfer position with respect to the rotation direction of the ball feed rotating body 350.
The positional relationship in a plan view of the ball feed rotating body 350 and the screw 25 is a positional relationship in which a game ball dropped from the top inclined surface 351b can be received between the pitches of the spiral protrusions 25d.
A cover member (not shown) is disposed along the outer periphery of the ball feed inclined portion 351 up to the vicinity of the delivery position to prevent the game ball from falling from the inclined surface 351a.

  A guide block 365 (FIGS. 54 and 55) is disposed on the upper surface of the lower gear box 357 in the vicinity of the lower front side of the screw 25. The guide block 365 has an arcuate sphere guide surface close to the spiral protrusion 25d of the screw 25, 365a, and a stopper surface 365b following this. The spherical guide surface is formed from the vicinity of the top inclined surface 351b to the opening 281 provided in the spiral base cover 352, and the tip is a stopper surface 365b (FIG. 55).

  Two lifting guide rails 282 are arranged adjacent to and parallel to the screw 25, and have a role of a guide for guiding a game ball lifted by the screw 25 linearly upward. The lifting guide rail 282 is located on the substantially opposite side to the ball feeding rotating body 350 with respect to the rotation direction of the screw 25, and from the position corresponding to the upper end of the opening 281 (FIG. 51) provided obliquely in the spiral base cover 352. It is arranged vertically upward, and its upper end is fixed to the lower surface of the upper gear box 356. The interval between two adjacent lifting guide rails 282 is a width through which a game ball (11 mm) cannot pass.

The lifting slope member 354 is a block member that faces the upper end of the screw 25 and is attached to the lower surface of the upper gear box 356. The lifting slope member 354 is disposed on the path through which the game balls are fed, and guides the game balls to the array passage 24. It has a slope to do.
The array passage 24 is provided at the upper end of the spiral base cover 352 and is a passage having an inclination for feeding the game ball guided from the lifting slope member 354 to the upper launching device 12.
Further, a ball removing member 355 for discharging game balls inside the gaming machine to the outside of the gaming machine is provided on a side surface of the arrangement passage 24. The ball removal member 355 is a detachable lid member, and can be removed from the side wall of the arrangement passage 24 by operating a lower knob to open an opening provided on the side wall. The array passage 24 includes a skew portion 24a, and a ball removing member 355 is disposed on the wall on the distal end side of the skew portion (FIG. 60).
Further, a launch ball standby ball detection switch 26 for detecting the presence or absence of a game ball is disposed on the outer surface of the array passage 24 (FIG. 57). When the firing standby ball detection switch 26 does not detect a game ball, the screw 25 is driven and new game balls are supplied from the ball lifting device 22 to the upper firing device 12 one by one.

[Operation of ball assembly 21 and ball lifting device 22]
The game balls sent from the deformed sphere / magnetic ball discharge unit 20 constituting a part of the circulation path pass through the ball feeding passage 275 of the ball collecting unit 21 and are sent to the ball feeding rotating body 350 in the ball lifting device 22. It is done. On the other hand, the screw 25 is rotated through the gear trains 358, 359 and 360 by driving the ball lifting motor 150, and the ball feed rotor 350 is rotated through the lower gear trains 362 and 363 through the screw shaft 25a. Is done. Since the gear ratio between the lower lifting gear 362 and the ball feed rotator gear 363 is 2: 1, the ball feed rotator 350 rotates once by the two rotations of the screw 25. The ball feed rotating body 350 receives and rotates game balls one by one from the ball feed passage 275 to the ball engaging recess 350a.
Thereafter, the rotation of the ball feed rotating body 350 causes the game ball to move while being engaged with the ball engaging recess, and the remaining outer half moves along the inclined surface 351a of the ball feed inclined portion 351, and the top inclined surface 351b. To reach. Since the top inclined surface 351b is inclined downward, the game ball naturally falls from the position onto the spiral protrusion 25d of the small pitch protrusion member 25b. At this time, the game balls falling from the top inclined surface 351b, which is slightly higher, have a larger distance from the subsequent game balls, and are reliably separated one by one.
Next, the game ball moves along the ball guide surface 365a of the guide block 365 with the rotation of the small pitch projecting member 25b and collides with the stopper surface 365b. During this time, the game ball rises with the rotation of the screw 25 and reaches the lower end of the opening 281 provided in the spiral base cover 352. In this case, as described above, the ball feed rotating body 350 includes the ball engaging recess 250a every 180 degrees and rotates at a speed of 1/2 with respect to the screw 25. A game ball is supplied to the screw 25. Since one half rotation of the ball feed rotator corresponds to one pitch of the small pitch ridge member 25b, a game ball sent from the ball feed rotator 350 is always one pitch between the pitches of the small pitch ridge members 25b. One by one and continuously. (FIG. 53).
That is, it is possible to prevent the game balls from being linked together in the ball lifting device 22.

  Through the opening 281, the ball polishing cloth 263 of the ball polishing cartridge 251 is brought into contact. That is, as the game ball is lifted by the screw 25 of the ball lifting device 22, the game ball is rubbed against the ball polishing cloth 263 through the opening 281 and the game ball is cleaned and polished (FIG. 51). And the area of the above-mentioned ball polishing cloth 263 can be used effectively by being guided diagonally upward.

  After passing through the opening 281, the game ball is lifted up to the upper end of the ball lifting device 22 as the screw 25 rotates. At this time, the game ball is placed on the lifting guide rail 282 arranged in parallel. It is guided and moves in a straight line. During this time, the game ball is lifted so that the movement of the game ball is relatively slow due to the small pitch at the small pitch protrusion member 25a in the lower part so that the ball receiving from the ball feed rotating body 350 is not hindered. Yes. In addition, since the pitch is small even at the upper small pitch protrusion member 25b, the movement of the game ball is made relatively slow so that the ball feeding to the upper launcher 12 is not hindered. On the other hand, in the middle part of the screw 25, there is no particular problem even if the speed of lifting the game ball is increased. The number of game balls to be circulated in the ball lifting device 22 can be reduced. Further, this can reduce the burden due to the weight of the game ball applied to the screw 25 (FIG. 57).

The game ball that has reached the upper end of the ball lifting device 22 abuts on the slope of the lifting slope member 354 and is guided in the direction of the arrangement path 24. The arrangement passage 24 has a gentle slope, and the game ball rolls on the slope and is sent to the upper launcher 12.
When it is necessary to take out the circulating game balls from the game machine, the ball removal member 355 provided on the outer surface of the arrangement passage 24 can be operated and easily discharged out of the game machine.

  In this embodiment, the spiral base cover 352 and the lifting unit cover 353 are made of a transparent resin (acrylic resin), and the state in the ball lifting device 22 is obtained by using such a transparent resin. However, the present invention is not limited to this, and the spiral base cover 352 and the lifting portion cover 353 may be made of an opaque resin, metal, or the like.

  Further, as shown in FIG. 14, in the arrangement passage 24, firing standby ball detection switches 26 and 27 may be arranged at positions lowered from the apexes of the arrangement passage 24 bent in a “he” shape (FIG. 14). . These switches 26 and 27 can detect the presence of three game balls. When the standby standby ball detection switches 26 and 27 do not detect a game ball, it is preferable that three new game balls are supplied from the screw 25.

  In addition, the small pitch ridge member 25b and the large pitch ridge member 25c are configured to be joined in half, but may be formed into a cylindrical shape integrally formed from the beginning. Furthermore, if the synthetic resin molding technique is used, the entire screw 25 except the screw shaft 25a can be integrally molded.

  Further, the screw 25 and the lifting guide rail 282 are preferably made of a slippery material, and may be a metal such as stainless steel or a synthetic resin. In addition, it is conceivable that the spiral protrusion 25d uses a hard silicon material or the like at least in a portion that receives the game ball from the ball feed rotating body 350. Thereby, the impact which arises when a game ball falls to the spiral protrusion 25d can be absorbed.

  Further, in the present embodiment, the game balls are sent and lifted one by one continuously in one pitch of the spiral protrusion 25d over the entire length of the screw 25. However, the game balls are lifted at the pitch of all the screws 25. Even if it is not sent, it is not limited to this as long as it is a configuration that continuously lifts the game balls.

  The ball lifting device 22 is not limited to a screw and may employ a belt mechanism. The game balls sent from the ball collecting unit 21 by the belt mechanism are sent to the upper launcher 12 through the arrangement passage 24. The ball lifting motor is arranged in a state where a gear is provided at the center lower part in the left-right direction of the belt mechanism, and the belt mechanism is operated by driving the ball lifting motor, and the game balls are put in the arrangement passage 24 one by one. It is supposed to be transported.

[Hitball launcher 29]
The hitting ball launching device 29 can hit the game ball supplied from the ball feeding device 28 into the game area 8 of the game board 5 with strength according to the rotation operation of the hitting ball handle 10. The ball striking device 29 includes a firing solenoid 13 that is attached to the upper rear surface of the base plate 39 so that the rotational drive shaft 60 protrudes forward, and a firing hammer 30 that is fixed to the rotational drive shaft 60 of the firing solenoid 13 so as to be integrally rotatable. A tip 61 fixed to the tip of the firing hammer 30, a rail member 33 attached to the front surface of the base plate 39 with a predetermined position on the movement trajectory of the tip 61 as a firing position, and the rail member 33 at the launch position. The firing stopper 34 that restricts the rotation of the tip 61 toward the rail member 33 from the hitting position where the stopped game ball can be hit and the firing hammer 30 are placed in a standby position (initial position) in the turning operation. ), A return ball stopper 35 for detecting the presence or absence of a game ball parked at the launch position, An upper launcher hinge 37, and a discharge orifice 38 which is opened to face the game area 8.

  Although the detailed illustration of the firing solenoid 13 in the hitting ball launching device 29 is omitted, the rotary drive shaft 60 is reciprocally rotated at a strength (speed) corresponding to the rotational operation angle of the hitting ball handle 10. The launching hammer 30 of the ball striking device 29 has a fixed portion 301 fixed to the rotational drive shaft 60 of the firing solenoid 13, and extends from the fixed portion 301 in a gentle arc shape, with the tip at the axis of the rotational drive shaft 60. A hook 302 facing the normal direction and having a hook 61 fixed to the tip thereof, and a stopper that extends to the opposite side of the hook 302 with the fixing part 301 sandwiched therebetween and can come into contact with the stopper 34 at the time of firing A contact portion 303. The stopper contact portion 303 of the firing hammer 30 contacts the stopper 34 at the time of firing, so that the tip 61 of the tip rotates more toward the firing rail than the hitting position (rotating end in the counterclockwise direction when viewed from the front). The movement is restricted (see FIG. 17).

  Further, a ball supply port 63 formed in a ball feed unit base (described later) of the ball feed device 28 is disposed immediately above the rail member 33 of the hit ball launching device 29. The rail member 33 stops one game ball sent out from the ball supply port 63 by the ball feeding operation of the ball feeding member 32 of the ball feeding device 28 described later at the launch position.

  The rail member 33 is formed by bending a metal plate. The rail plate 33 is attached and fixed to the base plate 39, and the rail portion 332 is bent forward from the mounting plate portion 331. (Refer to FIG. 17). The rail part 332 for setting the launch position is substantially L-shaped inclined 45 degrees to the left when viewed from the front, and includes a left rail plate 333 that forms the left side of the rail part 332 and a right side of the rail part 332. The right rail plate 334 is formed (see FIG. 17). The left rail plate 333 is formed with a through-hole 335 through which the tip 61 passes when the firing hammer 30 is struck (see FIGS. 8, 9, and 18).

  The launch port 38 is formed in the ball feed member 32 of the ball feed device 28, and is located obliquely right and upward in the front view with respect to the rail portion 332. As shown in FIGS. 16 and 17, the distance between the rail portion 332 (launch position) and the launch port 38 is short (about twice the diameter of the game ball). Without being generated, it is possible to reliably drive the launched game ball into the game area 8. In addition, a launch port decoration member 64 that decorates the right side of the launch port 38 is attached to the base plate 39 at the launch port 38.

The upper launcher 12 can be fired and a game is possible.

[During game]
When the player operates the hitting handle 10, the hitting ball launching device 29 is activated, and when the game ball at the ball launching position is launched into the game area 8 by the launching hammer 30, this is used for detecting the ball of the launching ball confirmation switch 36. Based on this, driving into each game area 8 for each game ball is detected. Then, the ball information control MPU 111 of the ball information control board 110 sequentially “1” from the game machine possession ball number data stored in the game machine possession ball number storage area in response to the detection of each game ball. And the number of balls held is displayed on the touch panel unit 14.

  On the other hand, the main control MPU 101 of the main control board 100 includes a gate switch 92 disposed on a gate (not shown) that allows game balls to pass through the game board 5 surface, and a normal winning opening (not shown). General winning opening detection switches 93 and 94 disposed on the counter, a count switch 98 disposed on the large winning opening (not shown), and a starting opening (not shown) serving as an upper starting opening. In addition, processing related to the game is performed based on the detection signals from the lower start port detection switches 90 and 91, and commands and signals as processing results are sent to the ball information control board 110, the peripheral control board 130, and the upper and lower special symbols. The data is output to the display units 142 and 143, the upper and lower special symbol storage displays 144 and 145, the normal symbol display unit 146, the normal symbol storage display unit 147, the starting port solenoid 96, the big winning port solenoid 97, and the like.

  When the game ball launched by the upper launcher 12 wins various winning holes in the game area 8 (starting winning hole, big winning hole, etc.), the game ball has various winning detection switches provided for each winning hole. (Upper start opening detection switch 90, lower start opening detection switch 91, general winning opening detection switch 93, general winning opening detection switch 94, count switch 98).

  The main control MPU 101 responds to detection signals from detection switches (general winning opening detection switches 93 and 94, count switch 98, upper and lower starting opening detection switches 90 and 91 are applicable) provided for each winning opening. A prize ball command for instructing the number of prize balls set according to the winning opening where the game ball has won is output to the ball information control board 110 as necessary.

  Further, the main control MPU 101 periodically outputs a gaming state signal (status) indicating the type of the current gaming state to the peripheral control board 130. The gaming state means, for example, a winning lottery due to a winning at the start opening and a start opening, a special symbol variable display based on the lottery result to stop the symbol, and the lottery result In the case of the first type pachinko gaming machine that shifts to the special gaming state (big hit gaming state) in the case of, the normal gaming state (the probability of winning by the lottery is normal probability, and the time of variable display of the normal symbol is normal), short time Game state (state that normal symbol variable display time is shortened than usual, time output information output signal), jackpot gaming state (15 round jackpot information output signal or 2 round jackpot information output signal), high probability game Status (probability of winning due to lottery, status change information output signal during probability change), special symbol change (special symbol display information output signal), hold based on start-up winnings There are certain conditions (starting opening winning information output signal) and the like.

  The peripheral control board 130 is based on a command output from the main control board 100, a liquid crystal display panel (not shown), an accessory decoration board (not shown), a board decoration board (not shown), and a frame decoration. By outputting a control signal to a substrate (not shown), the lighting display of various decorative LEDs is controlled, and sound (sound, sound, sound effect, etc.) output from a speaker (not shown) is controlled. The design of effect display on the liquid crystal display panel (not shown) is controlled.

  The sphere information control MPU 111 of the sphere information control board 110 displays the number of balls held in the launch solenoid 13, the ball feed solenoid 31, the ball lifting device 22, the touch panel unit 14 and the settlement machine 4 based on various input signals. Output a signal.

  A game state signal and a prize ball command output from the main control board 100 are input to the ball information control MPU 111 of the ball information control board 110.

  In response to receiving such a prize ball command, the ball information control MPU 111 sets the value of the number of prize balls set in advance for each winning slot in the gaming machine ball number data stored in the gaming machine ball number storage area. Are added and displayed on the touch panel unit 14.

[Game ends, settlement]
Thereafter, when the checkout button is operated by the player to end the game, the checkout machine 4 transmits a game end command to the ball information control MPU 111 of the ball information control board 110.

  When the settlement machine 4 transmits a game end command to the ball information control MPU 111 according to the operation of the settlement button, the ball information control MPU 111 receives the game end command sent from the settlement machine 4, and the ball information control The MPU 111 transmits “Finishable” to the settlement machine 4. Next, the ball information control MPU 111 stops the firing solenoid 13 and the ball feed solenoid 31 to stop the game. The current number of gaming machine balls stored in the gaming machine ball number storage area is transmitted to the settlement machine 4.

  Then, when the process of the settlement machine 4 corresponding to the number of gaming machine possessed balls transmitted from the ball information control MPU 111 is completed, the settlement machine 4 transmits a process end, so that the ball information control MPU 111 receives the process termination. Thus, the gaming machine possession ball number storage area in the RAM is cleared to 0, and the processing is completed.

  On the other hand, after the settlement machine 4 receives “end ready” as an answer to the end state in response to the game end command, the ball information control MPU 111 transmits the number of gaming machine balls to the settlement machine 4, so that the settlement machine 4 When the number of held balls is received, the received number of gaming machine balls is added to the number of adjusted machine balls stored in the RAM when the card is inserted, and the addition result is stored as the number of adjusted machine balls. Thereby, all of the number of possessed balls as the game result of the game played by the player is stored as the number of adjusted machine possessed balls. Then, the processing end is transmitted to the ball information control MPU 111, the number of adjusted machine balls is written in the number-of-balls storage unit 406 of the card 403, the card 403 is ejected from the card insertion slot, and the processing is ended. As a result, the card 403 rewritten by adding the number of gaming machine balls as a game result is returned to the player.

[Various control processing of main control board]
First, various control processes performed by the main control board 100 shown in FIG. 21 in accordance with the progress of the game of the pachinko machine 1 will be described with reference to FIGS. 24 is a flowchart showing a main control side power-on process executed by the main control MPU 101 of the main control board 100, and FIG. 25 is a flowchart showing a continuation of the main control side power-on process of FIG. FIG. 6 is a flowchart showing a main control timer interrupt process executed by the main control MPU 101. FIG.

[Main control side power-on processing]
When the pachinko machine 1 is powered on, the main control MPU 101 (hereinafter simply referred to as main control MPU) of the main control board 100 performs main control side power-on processing as shown in FIGS. When the main control side power-on process is started, the main control MPU sets the stack pointer (step S10). The stack pointer indicates, for example, the address accumulated on the stack to temporarily store the contents of the memory element (register) being used, or temporarily returns the return address of this routine when returning to this routine after completing the subroutine. It indicates the address that is stacked on the stack for storage, and the stack pointer advances each time the stack is stacked. In step S10, an initial address is set in the stack pointer, and the contents of the register, the return address, etc. are stacked on the stack from this initial address. Then, the stack pointer returns to the initial address by sequentially reading from the last stacked stack to the first stacked stack.

  Subsequent to step S10, wait timer processing 1 is performed (step S12), and it is determined whether or not a power failure warning signal is input (step S14). The voltage does not increase immediately from when the power is turned on until the voltage reaches the predetermined voltage. On the other hand, when a power outage or a momentary power interruption (a phenomenon in which the supply of power is suddenly stopped) occurs, the voltage decreases, and when it becomes smaller than the power outage notification voltage, the power outage monitoring circuit 117 of the ball information control board 110 notifies the power outage as a power outage notification. A signal is output and input to the main control MPU. Similarly, when the voltage becomes lower than the power failure notice voltage from when the power is turned on until it reaches the predetermined voltage, a power failure notice signal is input from the power failure monitoring circuit 117 of the ball information control board 110.

  Therefore, the wait timer process 1 in step S12 is a process for waiting after the power is turned on until the voltage becomes larger than the power failure warning voltage and stabilizes. In this embodiment, the wait timer process 200 waits for 200 milliseconds (wait timer) (wait timer). ms) is set. The determination in step S14 is performed based on a power failure warning signal from the power failure monitoring circuit 117 of the ball information control board 110. After the power is turned on, when the voltage becomes larger than the power failure warning voltage and becomes stable, the power failure warning signal from the power failure monitoring circuit 117 is not output, and the main control MPU proceeds to step S16.

  In step S16, the main control MPU determines whether or not the RAM clear switch 105 (FIG. 21) is operated (step S16). This determination is made based on whether or not the RAM clear switch 105 of the main control board 100 is operated and an operation signal (detection signal) is input to the main control MPU. When the detection signal is input, it is determined that the RAM clear switch 105 is operated. On the other hand, when the detection signal is not input, it is determined that the RAM clear switch 105 is not operated.

  When it is determined in step S16 that the RAM clear switch 105 is operated, the RAM clear notification flag RCL-FLG is set to a value 1 (step S18), and the process proceeds to step S30, while the RAM clear switch 105 is set in step S16. When it is determined that it is not operated, the RAM clear notification flag RCL-FLG is set to 0 (step S19), and the process proceeds to step S30.

  This RAM clear notification flag RCL-FLG is a game related to a game such as probability fluctuation, unpaid prize ball, etc. stored in a RAM (hereinafter referred to as “main control built-in RAM”) built in the main control MPU 101. It is a flag indicating whether or not to erase information, and is set to a value of 1 when erasing game information and a value of 0 when not erasing game information. Note that the value of the RAM clear notification flag RCL-FLG set in step S18 and step S19 is stored in a general-purpose storage element (general-purpose register) of the main control MPU.

  When the main control MPU proceeds to step S30, the main control MPU performs the wait timer process 2 (step S30). In this wait timer process 2, the system waits until a system that performs drawing control of a liquid crystal display device (not shown) by the liquid crystal control unit of the peripheral control board 130 starts (boots). In this embodiment, 2 seconds (s) is set as a time until booting (boot timer).

  Subsequent to step S30, it is determined whether or not the RAM clear notification flag RCL-FLG is 0 (step S32). As described above, the RAM clear notification flag RCL-FLG is set to a value of 1 when erasing game information and a value of 0 when not erasing game information. When it is determined in step S32 that the RAM clear notification flag RCL-FLG is 0, that is, when the game information is not erased, a checksum is calculated (step S34). This checksum is calculated by regarding the game information stored in the main control built-in RAM as a numerical value and calculating the sum.

  Following step S34, whether or not the calculated checksum value (sum value) matches the checksum value (sum value) stored in the main control side power-off processing (power-off) described later. Is determined (step S36). If they match, it is determined whether or not the backup flag BK-FLG is 1 (step S38). The backup flag BK-FLG is stored and held in the main control built-in RAM in the main control side power-off processing described later, such as game information, checksum value (sum value), and backup flag BK-FLG value. This flag is set to a value of 1 when the main control side power-off process is normally terminated, and to a value of 0 when the main control-side power-off process is not terminated normally.

  When the backup flag BK-FLG has a value of 1 in step S38, that is, when the main control side power-off process is normally terminated, the work area of the main control built-in RAM is set as power recovery (step S40). In this setting, in addition to setting the backup flag BK-FLG to a value of 0, the power recovery time information is read from the ROM built in the main control MPU (hereinafter referred to as “main control built-in ROM”). Time information is set in the work area of the main control built-in RAM. In addition, “recovery” means not only the state where the power is turned off but also the state where the power is turned on, the state where the power is restored after a power outage or a momentary power failure, and the detection that a high frequency has been applied. It also includes the state of returning after that.

  Subsequent to step S40, power-on command creation processing is performed (step S42). In the power-on command creation process, the game information is read from the backup information, and various commands corresponding to the game information are stored in a predetermined storage area of the main control built-in RAM.

  On the other hand, if it is determined in step S32 that the RAM clear notification flag RCL-FLG is not 0 (i.e., 1), that is, when the game information is deleted, or the checksum value (sum value) matches in step S36. If not, or if it is determined in step S38 that the backup flag BK-FLG is not a value 1 (value 0), that is, if the main control side power-off process has not been terminated normally, the main control built-in RAM All areas are cleared (step S44). Specifically, the value 0 is written in the main control built-in RAM (a predetermined value may be read from the main control built-in ROM as an initial value and set). Further, the big hit determination initial value determination random number used for determining the initial value of the big hit determination random number is when the RAM clear switch 105 is operated to erase the game information, the sum value does not match, or When the main control-side power-off process has not ended normally, a unique ID code stored in advance in the non-volatile RAM of the main control MPU is extracted, and the jackpot determination random number is updated based on the extracted ID code An initial value deriving process for always deriving the same fixed value from the fixed numerical value range of the counter is executed, and this fixed value is set as the initial value.

  Following step S44, the work area of the main control built-in RAM is set as an initial setting (step S46). In this setting, initial information is read from the main control built-in ROM, and this initial information is set in the work area of the main control built-in RAM.

  Subsequent to step S46, RAM clear notification and test command creation processing is performed (step S48). In the RAM clear notification and test command creation processing, a power-on command classified into power-on for notifying that the main control built-in RAM is cleared and the initial setting is performed is created, and various peripheral control board 130 Test commands that are classified as related to tests for inspection are created and stored as transmission information in the transmission information storage area of the main control built-in RAM.

  Subsequent to step S42 or step S48, interrupt initialization is performed (step S50). This setting is to set an interrupt cycle when a main control timer interrupt process described later is performed. In this embodiment, it is set to 4 ms.

  Subsequent to step S50, interrupt permission is set. (Step S52). With this setting, the main control side timer interrupt process is repeated every interrupt cycle set in step S50, that is, every 4 ms. The processing in steps S10 to S52 is referred to as “main control side power-on processing”.

  Subsequent to step S52, a value A is set in the watchdog timer clear register WCL (step S54). The watchdog timer is cleared by setting value A, value B and value C in this order in this watchdog timer clear register WCL.

  Subsequent to step S54, it is determined whether or not a power failure warning signal is input (step S56). As described above, when the power of the pachinko gaming machine 1 is cut off, or when a power failure or a momentary power failure occurs, if the voltage falls below the power failure warning voltage, the power failure warning signal is displayed as a power failure monitoring circuit of the ball information control board 110. 117 is input. The determination in step S56 is made based on this power failure notice signal.

  If no power failure warning signal is input in step S56, a non-winning random number update process is performed (step S58). In this non-winning random number update process, for example, a reach determination random number, a variable display pattern random number, a big hit symbol initial value determining random number, a small hit symbol initial value determining random number, and the like are updated. In this way, in the non-winning random number update process, random numbers that are not involved in the winning determination (big hit determination) are updated. It should be noted that the random number for normal symbol determination, the random number for initial value determination for normal symbol determination, the random number for normal symbol variation display pattern, and the like are also updated by this non-winning random number update process.

  Following step S58, the process returns to step S54 again to set the value A in the watchdog timer clear register WCL. In step S56, it is determined whether or not a power failure warning signal has been input. For example, a non-winning random number update process is performed in step S58, and steps S54 to S58 are repeated. The processing from step S54 to step S58 is referred to as “main control side main loop processing”.

  On the other hand, when a power failure warning signal is input in step S56, interrupt prohibition setting is performed (step S60). With this setting, the main control side timer interrupt processing described later is not performed, writing to the main control built-in RAM is prevented, and rewriting of game information is protected.

  Subsequent to step S60, the start opening solenoid 96, the big prize opening solenoid 97, the upper special symbol display 142, the lower special symbol display 143, the upper special symbol storage display 144, and the lower special symbol storage display shown in FIG. The drive signal output to the display unit 145, the normal symbol display unit 146, the normal symbol storage display unit 147, the game state display unit 148, the round display unit 149, etc. is stopped (step S62).

  Subsequent to step S62, a checksum is calculated and the calculated value is stored (step S64). This checksum is calculated by regarding the game information in the work area of the main control built-in RAM as a numerical value excluding the storage area for the checksum value (sum value) and backup flag BK-FLG described above.

  Subsequent to step S64, a value 1 is set in the backup flag BK-FLG (step S66). Thereby, the storage of the backup information is completed.

  Subsequent to step S66, the watchdog timer is cleared (step S68). As described above, the clear setting is performed by sequentially setting the value A, the value B, and the value C in the watchdog timer clear register WCL.

  Subsequent to step S68, a loop process of repeating a state in which nothing is executed is entered. Note that the processing and the loop processing in steps S60 to S68 are referred to as “main control side power-off processing”. In this loop processing, since the value A, the value B, and the value C are not sequentially set in the watchdog timer clear register WCL, the watchdog timer is not cleared. Therefore, the watchdog timer times out and outputs a time-out signal, and the main control MPU is reset by the time-out signal, and then the main control MPU performs this main control side power-on process from the beginning again.

  The pachinko machine 1 (main control MPU 101) is reset when a power failure occurs or when a momentary power failure occurs, and performs power-on processing on the main control side by subsequent power recovery.

  In step S36, it is checked whether or not the backup information stored in the main control built-in RAM is normal. In step S38, it is determined whether or not the main control side power-off process has been normally completed. I am inspecting. In this way, by checking the backup information stored in the main control built-in RAM twice, it is inspected whether the backup information is stored by an illegal act.

[Main control timer interrupt processing]
Next, the main control timer interrupt process will be described. This main control side timer interrupt process is repeatedly performed every interrupt period (4 ms in the present embodiment) set in the main control side power-on process shown in FIGS.

  When the main control timer interrupt process is started, the main control MPU of the main control board 100 sets a value B in the watchdog timer clear register WCL as shown in FIG. 26 (step S70). At this time, the value B is set in the watchdog timer clear register WCL following the value A set in step S54 of the main loop on the main control side.

  Subsequent to step S70, the interrupt flag is cleared (step S72). When the interrupt flag is cleared, the interrupt cycle is initialized, and the next interrupt cycle is counted from the initial value.

  Subsequent to step S72, switch input processing is performed (step S74). In this switch input process, various signals input to the input terminal of the main control I / O port 102 are read and stored as input information in the input information storage area of the main control built-in RAM.

  Subsequent to step S74, timer subtraction processing is performed (step S76). In this timer subtraction process, for example, the time during which the upper special symbol display unit 142 and the lower special symbol display unit 143 are turned on in accordance with the variable display pattern determined in the special symbol and special electric accessory control process described later, In addition to the time that the normal symbol display 146 is turned on according to the normal symbol variation display pattern determined in the normal electric accessory control process, the ball information control substrate 110 receives various commands transmitted by the main control board 100 (main control MPU). Time management such as an ACK signal input determination time set as a determination condition is performed when determining whether or not a ball information main ACK signal that indicates normal reception is input. Specifically, when the fluctuation time of the fluctuation display pattern or the normal symbol fluctuation display pattern is 5 seconds, the timer interruption period is set to 4 ms. Therefore, every time this timer subtraction process is performed, the fluctuation time is subtracted by 4 ms. When the subtraction result is 0, the fluctuation time of the fluctuation display pattern or the normal symbol fluctuation display pattern is accurately measured.

  In this embodiment, the ACK signal input determination time is set to 100 ms. Each time this timer subtraction process is performed, the ACK signal input determination time is subtracted by 4 ms, and the result of the subtraction becomes 0, thereby accurately measuring the ACK signal input determination time. The various times and the ACK signal input determination time are stored as time management information in the time management information storage area of the main control built-in RAM.

  Subsequent to step S76, a winning random number update process is performed (step S78). In the winning random number update process, the big hit determination random number, the big hit symbol random number, and the small hit symbol random number described above are updated. Further, in addition to these random numbers, a big hit symbol initial value determination random number that is updated by the non-winning random number update process of step S58 in the main control side power-on process (main control side main process) shown in FIG. And the random number for determining the initial value for the small hit symbol is also updated. These random numbers for determining the initial value for the big hit symbol and the random numbers for determining the initial value for the small hit symbol are updated in the main control side main process and the main control side timer interrupt process, respectively, thereby increasing the randomness. . On the other hand, since the big hit determination random number, the big hit symbol random number, and the small hit symbol random number are random numbers related to the winning determination (big hit determination), each time the winning random number update process is performed, each counter Counts up. For example, the counter for updating the jackpot determination random number is an initial value updating type counter as described above, and is a predetermined fixed numerical value range from the minimum value to the maximum value (in this embodiment, the value as the minimum value). 0 to the maximum value is updated within the value 32767), and the range from the minimum value to the maximum value is incremented by incrementing by 1 each time the main control timer interrupt processing is performed. The big hit determination initial value determination random number is counted up toward the maximum value (value 32767), and then the big hit determination initial value determination random number is counted up. When the counter for updating the big hit determination random number finishes counting up within the range from the minimum value to the maximum value of the big hit determination random number, the big hit determination initial value determination random number is updated by the winning random number update processing. At this time, the updated value is always the same from the fixed numerical value range of the counter in which the main control MPU extracts the ID code from the built-in nonvolatile RAM and updates the big hit determination random number based on the extracted ID code. An initial value deriving process for deriving a fixed value of is performed, and the derived fixed value is set as an initial value. In other words, the initial value determination random number for jackpot determination is always overwritten and updated with the same fixed value derived based on the ID code as a result of execution of the initial value derivation process. Note that the above-described random numbers for normal symbol determination and random numbers for determining the initial value for normal symbol determination are also updated by this winning random number update process. The random number for determining normal symbols is the same as the method for updating the random number for determining big hits, and the description thereof is omitted.

  Subsequent to step S78, prize ball control processing is performed (step S80). In this prize ball control process, the input information is read from the above-described input information storage area and a prize ball command for transmitting to the ball information control board 110 based on this input information is created, or the main control board 100 and the ball information A self-check command for confirming a connection state between the control board 110 and the board is created. Then, the created prize ball command and self-check command are transmitted to the ball information control board 110 as main ball information serial data. For example, when one game ball enters the big prize opening, a prize ball command representing 15 balls as the number of prize balls is created and transmitted to the ball information control board 110, or this prize ball command is sent to the ball information control board. When a ball information main ACK signal notifying that 110 has been successfully received is not input within a predetermined time, a self-check command is generated to check the connection state between the main control board 100 and the ball information control board 110. Or transmitted to the sphere information control board 110.

  Subsequent to step S80, frame command reception processing is performed (step S82). The sphere information control board 110 transmits various commands of 1 byte (8 bits) divided into status displays. In the frame command reception process in step S82, when these various commands are normally received as the sphere information main serial data, information that informs the sphere information control board 110 to the effect is stored in the output information storage area of the main control built-in RAM as output information. Remember. Further, the command normally received as the sphere information main serial data is shaped into a 2-byte (16-bit) command and stored as transmission information in the transmission information storage area described above.

  Subsequent to step S82, fraud detection processing is performed (step S84). In this fraud detection process, the abnormal state related to the prize ball is confirmed. For example, when the input information is read from the above-described input information storage area and the detection signal from the count switch 98 is input when the game is not in the big hit game state (when the game ball enters the big winning opening), etc. A winning abnormality display command that is classified as a notification display as an abnormal state is created and stored as transmission information in the transmission information storage area described above.

  Subsequent to step S84, a special symbol and special electric accessory control process is performed (step S86). In this special symbol and special electric accessory control processing, the value of the counter for updating the jackpot determination random number described above is taken out, and it is determined whether or not it matches the jackpot determination value stored in advance in the main control built-in ROM. It is determined whether or not a gaming state is to be generated (referred to as “special lottery”)), or a counter value for updating the jackpot symbol random number is extracted, and the probability variation hit determination value stored in advance in the main control built-in ROM It is determined whether or not they match (determining whether or not probability fluctuations are generated). Here, “probability fluctuation” means that the probability of a big hit changes to a high probability (at the time of probability change) that is set higher than that at normal time (low probability). In the present embodiment, the value 32668 to the value 32767 are set in the low probability as the range of the big hit determination value (big hit determination range) described above, and read from the normal determination table, whereas the value 32438 in the high probability. ˜value 32767 is set and read from the probability variation determination table. As described above, in the special symbol and special electric accessory control process in step S86, the value of the counter for updating the big hit determination random number matches the big hit determination value stored in advance in the main control built-in ROM. Is determined depending on whether or not the value of the counter for updating the jackpot determination random number is included in the jackpot determination range.

  When these determination results are based on the upper start opening detection switch 90, various commands related to the special effect shown in FIG. 1 are produced. On the other hand, when the lottery results are based on the lower start opening detection switch 91, FIG. 2 Various commands related to the tuning effect are created and stored in the transmission information storage area as transmission information, and the upper special symbol display 142 or the lower special symbol display 143 is turned on according to the determined special symbol variation display pattern. The lighting signal output to the upper special symbol display 142 or the lower special symbol display 143 is set and stored as output information in the output information storage area described above.

  Also, depending on the gaming state to be generated, for example, when the big hit gaming state is entered, various commands classified as jackpot related are created and stored as transmission information in the transmission information storage area, or the opening / closing member is opened and closed. When the output of the drive signal to the winning opening solenoid 97 is set and stored in the output information storage area as output information, or when the number of times that the large winning opening is changed from the closed state to the opened state (round) is two times, the round display The lighting signal output to the two-round display lamp is set so that the two-round display lamp of the device 149 is lit, and stored in the output information storage area as output information, or when the round is 15 times, Set the output of the lighting signal to the 15 round display lamp to light the 15 round display lamp, and output information as output information. And stores in the storage area, presence or absence of occurrence probability variations sets the output of the lighting signal to the game state indicator 148 to be lit in a predetermined color, or stored in the output information storage area as the output information.

  Subsequent to step S86, normal symbol and normal electric accessory control processing is performed (step S88). In the normal symbol and normal electric accessory control process, the input information is read from the above-described input information storage area, and the gate winning process is performed based on the input information. In this gate winning process, it is determined from the input information whether the detection signal from the gate switch 92 has been input to the input terminal. Based on this determination result, when a detection signal is input to the input terminal, the gate information storage area of the main control built-in RAM is extracted as gate information by extracting the counter value etc. for updating the random number for determination per normal symbol described above To remember.

  Subsequent to step S88, port output processing is performed (step S90). In this port output process, output information is read from the output information storage area described above from the output terminal of the main control I / O port 102, and various signals are output based on this output information. For example, the main sphere information ACK signal is output to the sphere information control board 110 when various commands from the sphere information control board 110 are normally received from the output terminal of the main control I / O port 102 based on the output information. When in the big hit gaming state, a driving signal is output to the big winning opening solenoid 97 for opening / closing the opening / closing member of the big winning opening, or a driving signal is output to the starting opening solenoid 96 for opening / closing the movable piece. In addition, 15 rounds jackpot information output signal, 2 rounds jackpot information output signal, probability changing information output signal, special symbol display information output signal, normal symbol display information output signal, short and medium time information output information, start opening prize information output signal For example, various information (game information) signals relating to the game such as, are output to the ball information control board 110.

  Subsequent to step S90, peripheral control board command transmission processing is performed (step S92). In the peripheral control board command transmission process, the transmission information is read from the transmission information storage area described above, and the transmission information is transmitted to the peripheral control board 130 as main peripheral serial data. This transmission information includes various commands created in the main control side timer interrupt processing, which is this routine, classified as related to the special figure 1 tuning effect, various commands classified as related to the special figure 2 synchronous effect, and classified as related to the jackpot. Various commands that are classified as power-on, various commands that are classified as related to ordinary drawing effects, various commands that are classified as related to ordinary electronic effects, various commands that are classified into notification displays, and status displays Various commands classified, various commands classified as related to tests, and various commands classified into others are stored. The main serial data consists of 3 bytes per packet.

  Specifically, the main peripheral serial data includes a status indicating a type of command having a storage capacity of 1 byte (8 bits), a mode indicating a production variation having a storage capacity of 1 byte (8 bits), and a status. And a sum value obtained by calculating the sum with the mode regarded as a numerical value, and this sum value is created at the time of transmission. The processing from step S74 to step S92 is referred to as “game control processing”.

  Subsequent to step S92, a value C is set in the watchdog timer clear register WCL (step S94). By setting the value C in the watchdog timer clear register WCL in step S94, the value C is set in the watchdog timer clear register WCL following the value B set in step S70. As a result, the value A, the value B, and the value C are sequentially set in the watchdog timer clear register WCL, and the watchdog timer is cleared.

  Subsequent to step S94, the register is switched (returned) (step S96), and this routine is terminated. Here, when the main control side timer interrupt processing, which is this routine, is started, the main control MPU loads the contents of the general-purpose registers on the stack and saves them. This prevents the contents of the general-purpose register used in the main process on the main control side from being destroyed. In step S96, the contents saved on the stack are read and written to the original register. The main control MPU sets interrupt permission after the return in step S96.

[Various control processing of sphere information control board]
Next, various control processes performed by the sphere information control board 110 shown in FIG. 22 will be described with reference to FIGS. 27 is a flowchart showing a sphere information control side power-on process executed by the sphere information control MPU 111 of the sphere information control board 110, and FIG. 28 is a flowchart showing a continuation of the sphere information control side power-on process of FIG. FIG. 29 is a flowchart showing the continuation of the power-on processing on the sphere information control side following FIG. 28, and FIG. 30 shows the sphere information control power-off processing executed by the sphere information control MPU 111 of the sphere information control board 110 FIG. 31 is a flowchart showing an example of the ball information control side timer interruption process.

[Ball information control side power-on processing]
When the pachinko gaming machine 1 is powered on, the ball information control MPU 111 (hereinafter simply referred to as the ball information control MPU) of the ball information control unit 118 on the ball information control board 110 is as shown in FIGS. Sphere information control side power-on processing is performed. When the ball information control side power-on process is started, the ball information control MPU sets an interrupt mode (step S500). This interrupt mode is for setting the priority order of interrupts of the sphere information control MPU. In this embodiment, a sphere information control unit timer interrupt process, which will be described later, is set as the highest priority, and when an interrupt of this sphere information control unit timer interrupt process occurs, the process is preferentially performed.

  Subsequent to step S500, input / output setting (I / O input / output setting) is performed (step S502). In this I / O input / output setting, the I / O port input / output setting of the sphere information control MPU is performed.

  Subsequent to step S502, output of a power failure clear signal is started to the power failure monitoring circuit 117 shown in FIG. 22 (step S504). The power failure monitoring circuit 117 is composed of a voltage comparison circuit and a D-type flip-flop IC. The voltage comparison circuit compares the voltage between + 24V and the reference voltage, or compares the voltage between + 12V and the reference voltage, and outputs the comparison result. This comparison result shows that when no power failure or instantaneous power failure occurs, the logic becomes HI and is input to the PR terminal which is the preset terminal of the D-type flip-flop. The logic becomes LOW and is inputted to the PR terminal which is a preset terminal of the D-type flip-flop. In step S504, output of the power failure clear signal is started to the CLR terminal which is the clear terminal of the D type flip-flop. This power failure clear signal is input to the clear terminal with the logic being LOW via the ball information control I / O port 112 of the ball information control unit 118. Thereby, the sphere information control MPU can release the latch state of the D-type flip-flop, and inverts the logic input to the PR terminal which is the preset terminal of the D-type flip-flop until the latch state is set. Thus, the output from the 1Q terminal, which is the output terminal, can be made, and the signal from the 1Q terminal can be monitored.

  Subsequent to step S504, wait timer processing 1 is performed (step S506), and it is determined whether or not a power failure warning signal is input (step S508). The voltage does not increase immediately from when the power is turned on until the voltage reaches the predetermined voltage. On the other hand, when there is a power failure or a momentary power failure (a phenomenon in which the supply of power is temporarily stopped), the voltage decreases, and when it becomes lower than the power failure warning voltage, a power failure warning signal is input from the power failure monitoring circuit 117 as a power failure warning. Similarly, when the voltage becomes lower than the power failure warning voltage from when the power is turned on until it reaches the predetermined voltage, a power failure warning signal is input from the power failure monitoring circuit 117. Therefore, the wait timer process 1 in step S506 is a process for waiting until the voltage becomes larger than the power failure warning voltage and stabilizes after the power is turned on. In this embodiment, the wait timer process 200 waits for 200 milliseconds (wait timer) (wait timer). ms) is set. In step S508, it is determined whether or not the power failure notice signal is input. This determination is performed based on the signal output from the 1Q terminal, which is the output terminal of the D-type flip-flop described above, as the power failure warning signal.

  Subsequent to step S508, the output of the power failure clear signal is stopped at the CLR terminal which is the clear terminal of the D-type flip-flop (step S510). By stopping the output of the power failure clear signal, the logic becomes HI via the ball information control I / O port 112 and is input to the CLR terminal which is a clear terminal. Thereby, the sphere information control MPU can set the D-type flip-flop in the latched state. When the D-type flip-flop latches the state that the logic is LOW and is input to the PR terminal that is the preset terminal, the D-type flip-flop outputs a power failure warning signal from the 1Q terminal that is the output terminal.

  Subsequent to step S510, it is determined whether or not the RAM clear switch 105 is operated (step S512). This determination is made based on whether or not the RAM clear switch 105 of the main control board 100 is operated and an operation signal (detection signal) is input to the sphere information control MPU. When the detection signal is input, it is determined that the RAM clear switch 105 is operated. On the other hand, when the detection signal is not input, it is determined that the RAM clear switch 105 is not operated.

  If it is determined in step S512 that the RAM clear switch 105 is operated, the value 1 is set in the sphere information RAM clear flag (step S514), and the process proceeds to step S518, while the RAM clear switch 105 is operated in step S512. If it is determined that it is not, the value 0 is set in the ball information RAM clear (step S516), and the process proceeds to step S518.

  The sphere information RAM clear flag is stored in, for example, various flags and various information storage areas stored in a RAM (hereinafter referred to as “sphere information control built-in RAM”) built in the sphere information control MPU. It is a flag indicating whether or not to delete various sphere information, and is set to a value of 1 when the sphere information is deleted and a value of 0 when the sphere information is not deleted. The sphere information RAM clear flag set in step S514 and step S516 is stored in a general-purpose storage element (general-purpose register) of the sphere information control MPU.

  Subsequent to step S514 or step S516, setting for permitting access to the spherical information control built-in RAM is performed (step S518). This setting allows access to the sphere information control built-in RAM, for example, writing (storage) or reading of the sphere information.

  Subsequent to step S518, the stack pointer is set (step S520). The stack pointer indicates, for example, the address accumulated on the stack to temporarily store the contents of the memory element (register) in use, or temporarily returns the return address of this routine when returning to this routine after completing the subroutine. It indicates the address that is stacked on the stack for storage, and the stack pointer advances each time the stack is stacked. In step S520, an initial address is set in the stack pointer, and the contents of the register, the return address, etc. are stacked on the stack from this initial address. Then, the stack pointer returns to the initial address by sequentially reading from the last stacked stack to the first stacked stack.

  Subsequent to step S520, the sphere information control MPU proceeds to step S527. In step S527, it is determined whether or not the sphere information RAM clear flag is 0 (step S527). As described above, the sphere information RAM clear flag is set to a value of 1 when the sphere information is erased, and a value of 0 when the sphere information is not erased.

  When the sphere information RAM clear flag is 0 in step S527, that is, when the sphere information is not deleted, a checksum is calculated (step S528). This checksum calculates the sum by regarding the sphere information stored in the sphere information control built-in RAM as a numerical value.

  Subsequent to step S528, it is determined whether or not the calculated checksum value matches a checksum value stored in a sphere information control unit power-off process (power-off) described later (step S530). ). If they match, it is determined whether or not the sphere information backup flag is 1 (step S532). This sphere information backup flag is a flag indicating whether or not sphere information backup information such as sphere information and checksum value is stored and held in the sphere information control built-in RAM in the sphere information control unit power-off process described later. A value of 1 is set when the sphere information control unit power-off process is normally terminated, and a value of 0 is set when the sphere information control unit power-off process is not terminated normally.

  When the sphere information backup flag has a value of 1 in step S532, that is, when the sphere information control unit power-off process is normally terminated, the work area of the sphere information control built-in RAM is set as power recovery (step S534). In this setting, in addition to setting the value 0 to the sphere information backup flag, the power recovery time information is read from a ROM built in the sphere information control MPU (hereinafter referred to as “sphere information control built-in ROM”). The power recovery information is set in the work area of the ball information control built-in RAM. Thereby, the information used for various processes is set based on the various information stored in the various information storage areas, such as various flags, which are the above-described spherical information backup information stored in the spherical information control built-in RAM. . Note that “recovery” includes not only a state in which the power is turned off from a state in which the power is turned off but also a state in which the power is restored after a power failure or a momentary power failure.

  On the other hand, if it is determined in step S527 that the sphere information RAM clear flag is not 0 (value 1), or if the checksum values do not match in step S530, or the sphere information backup flag is set in step S532. When it is determined that the value is not 1 (value 0), that is, when the process of turning off the power of the sphere information control unit is not normally terminated, the entire area of the sphere information control built-in RAM is cleared (step S536). Thereby, the sphere information backup information stored in the sphere information control built-in RAM is cleared.

  Subsequent to step S536, the work area of the sphere information control built-in RAM is set as an initial setting (step S538). In this setting, the initial information is read from the sphere information control built-in ROM, and the initial information is set in the work area of the sphere information control built-in RAM.

  Subsequent to step S534 or step S538, interrupt initialization is performed (step S540). This setting is to set an interrupt cycle when a sphere information control unit timer interrupt process described later is performed. In this embodiment, it is set to 2 ms.

  Subsequent to step S540, interrupt permission setting is performed (step S542). With this setting, the sphere information control unit timer interruption process is repeatedly performed every interruption period set in step S540, that is, every 2 ms.

  Subsequent to step S542, it is determined whether or not a power failure warning signal is input (step S544). As described above, when the power of the pachinko gaming machine 1 is cut off, or when a power failure or a momentary power failure occurs, a power failure warning signal is input from the power failure monitoring circuit 117 as a power failure warning voltage when the voltage becomes equal to or lower than the power failure warning voltage. The determination in step S540 is made based on this power failure notice signal.

  When no power failure warning signal is input in step S544, it is determined whether or not the 2 ms elapsed flag HT-FLG is 1 (step S546). This 2 ms elapsed flag HT-FLG is a flag that measures 2 ms in a sphere information control unit timer interrupt process that is processed every 2 ms, which will be described later. The value is 1 when 2 ms has elapsed and 1 when the time has not elapsed. Each is set.

  If it is determined in step S546 that the 2 ms elapsed flag HT-FLG has a value of 0, that is, if 2 ms has not elapsed, the process returns to step S544 to determine whether a power failure warning signal is input.

  On the other hand, if it is determined in step S546 that the 2 ms elapsed flag HT-FLG has a value of 1, that is, if 2 ms have elapsed, a value 0 is set in the 2 ms elapsed flag HT-FLG (step S547), and the process proceeds to step S550. Then, an external WDT clear signal is output to the external watchdog timer (external WDT) 116 (turned ON, step S550). The external WDT 116 monitors the operation (system) of the sphere information control MPU. When the external WDT clear signal is not stopped at the clear signal release time, a reset signal is sent to the sphere information control MPU and the sphere information control I / O port 112. Is output and reset (periodically diagnoses whether or not the system of the sphere information control MPU is out of control).

  Subsequent to step S550, port output processing is performed (step S552). In this port output process, various information is read from the output information storage area of the spherical information control built-in RAM, and various signals are output from the output terminal of the spherical information control I / O port 112 based on the various information.

  In the output information storage area, for example, ball information main ACK information indicating that various commands (prize ball command and self-check command) related to the prize ball from the main control board 100 have been normally received, Various information such as drive information for performing drive control is stored, and when a prize ball command from the main control board 100 is normally received from the output terminal of the ball information control I / O port 112 based on this output information. The ball information main ACK signal is output to the main control board 100, or the drive signal is output to the firing solenoid 13.

  Subsequent to step S552, port input processing is performed (step S554). In this port input process, various signals input to the input terminal of the sphere information control I / O port 112 are read and stored as input information in the input information storage area of the sphere information control built-in RAM. For example, from the door frame opening switch 131, the body frame opening switch 132, the firing standby ball detection switches 26, 27, 70, the firing ball confirmation switch 36, the collected ball detection switch 203, the firing stop switch 86, the touch switch 87, and the checkout machine 4 BRQ signal, BRDY signal, CR connection signal, and main sphere information ACK signal from the main control board 100 that indicates that the main control board 100 has normally received various commands transmitted in the command transmission process described later, respectively. And stored as input information in the input information storage area.

  Subsequent to step S554, timer update processing is performed (step S556). The various determination times are stored as time management information in the time management information storage area of the sphere information control built-in RAM. In the timer update process, it is determined whether or not the timer values of various timers are set. If the timer value is set, 1 is subtracted from the timer value. For example, when “1000” is set as a value corresponding to 2 seconds (2000 ms) in the timer, the timer interrupt period is set to 2 ms. Therefore, the timer value is incremented by 1 every time the timer subtraction process is performed in the 2 ms period. Subtraction is performed, and when the subtraction result becomes 0, the time is up, and the time is accurately measured.

  Subsequent to step S556, settlement machine communication processing is performed (step S558). In the settlement machine communication processing, whether or not various signals (BRQ signal, BRDY signal, and CR connection signal) from the settlement machine 4 are input based on the input information read from the input information storage area described above. Determine. Based on various signals from the settlement machine 4, the ball information control MPU exchanges various signals with the settlement machine 4. For example, when the ball information control MPU receives the number of balls lent transmitted from the checkout machine 4, the ball information control MPU adds the number of balls rented to the number of balls held by the gaming machine.

  Following step S558, command reception processing is performed (step S560). In this command reception process, various commands (prize ball commands and self-check commands) related to prize balls from the main control board 100 are received. When these various commands are normally received, the sphere information main ACK information to that effect is stored in the output information storage area described above. On the other hand, when various commands cannot be received normally, a connection that indicates that an abnormality has occurred in the connection between the main control board 100 and the ball information control board 110 (an abnormality has occurred in various command signals). Abnormality information is stored in the state information storage area described above.

  Following step S560, command analysis processing is performed (step S562). In this command analysis processing, the command received in step S562 is analyzed, and the analyzed command is stored as received command information in the received command information storage area of the sphere information control built-in RAM.

  Subsequent to step S562, main operation setting processing is performed (step S564). In this main operation setting process, the ball information control MPU performs operation settings of the firing solenoid 13, the ball feeding solenoid 31, the ball lifting device 22, and the like. In addition, the ball information control MPU sequentially “1” from the game machine ball number data stored in the game machine ball number storage area in response to the detection of each game ball shot based on the ball detection of the launch ball confirmation switch 36. "Is subtracted. Further, when a winning ball command is stored in the received command information storage area, the number of winning balls corresponding to the winning ball command is added to the gaming machine ball number data stored in the gaming machine holding ball number storage area.

  Following step S564, LED display data creation processing is performed (step S566). In this LED display data creation process, for example, the gaming machine possession ball number data stored in the above-mentioned gaming machine possession ball number storage area is read out, and display data for displaying the number of possession balls on the touch panel unit 14 is created. The display information is stored in the output information storage area described above.

  Subsequent to step S566, command transmission processing is performed (step S568). In this command transmission process, various information is read from the state information storage area described above, and various commands classified into status displays are created based on the various information and transmitted to the main control board 100.

  Subsequent to step S568, output of the external WDT clear signal to the external watchdog timer (external WDT) 116 is stopped (turns OFF, step S570). Thereby, the external WDT 116 is cleared so that the sphere information control MPU and the sphere information control I / O port 112 are not reset. The external WDT 116 starts counting the clear signal release time when the output of the external WDT clear signal is stopped.

  Following step S570, the process returns to step S544 again to determine whether or not a power failure warning signal is input. If this power failure warning signal is not input, the 2 ms elapsed flag HT-FLG is 1 in step S546. When the 2 ms elapsed flag HT-FLG has a value of 1, that is, when 2 ms have elapsed, the value 0 is set in the 2 ms elapsed flag HT-FLG in step S547, and the external WDT 4120c is externally connected in step S550. A WDT clear signal is output (ON), port output processing is performed in step S552, port input processing is performed in step S554, timer update processing is performed in step S556, settlement machine communication processing is performed in step S558, and step S560 is performed. Command reception processing is performed, and command analysis processing is performed in step S562. In step S564, main operation setting processing is performed. In step S566, LED display data creation processing is performed. In step S568, command transmission processing is performed. In step S570, the output of the external WDT clear signal is stopped (OFF). Steps S544 to S570 are repeated. The processing from step S544 to step S570 is referred to as “sphere information control main processing”.

  On the other hand, when a power failure warning signal is input in step S544, interrupt prohibition setting is performed (step S572). With this setting, a sphere information control unit timer interrupt process, which will be described later, is not performed, writing to the sphere information control built-in RAM is prevented, and the rewriting of the sphere information described above is protected.

  Subsequent to step S572, the power failure clear signal is output to the CLR terminal, which is the clear terminal of the D-type flip-flop of the power failure monitoring circuit 117, via the ball information control I / O port 112 (step S574). Thereby, the D type flip-flop can be released from the latched state by outputting the power failure clear signal.

  Subsequent to step S574, output of the drive signal to the firing solenoid 13 is stopped (step S576). Thereby, the launch of the game ball is stopped. Subsequent to step S576, output of the drive signal to the ball feed solenoid 31 is stopped (step S578). Thereby, the feeding of the game ball to the hit ball launching device 29 side is stopped.

  Subsequent to step S578, an external WDT clear signal is output to the external WDT 116 and the output is stopped (ON / OFF, step S580). As a result, the external WDT 116 is cleared. Subsequent to step S580, a checksum is calculated and the calculated value is stored (step S582). The checksum is calculated by considering the sphere information in the work area of the sphere information control built-in RAM as a numerical value, excluding the storage area of the checksum value calculated in step S528 and the value of the sphere information backup flag HBK-FLG. To do. Subsequent to step S582, a value 1 is set in the sphere information backup flag (step S584). Thereby, the storage of the sphere information backup information is completed. Subsequent to step S584, access prohibition to the sphere information control built-in RAM is set (step S586). With this setting, access to the sphere information control built-in RAM is prohibited, and writing and reading cannot be performed, and the sphere information backup information stored in the sphere information control built-in RAM is protected.

  Subsequent to step S586, a loop process of repeating a state of doing nothing is entered. In this loop processing, the clear signal is not turned ON / OFF to the external WDT 116. Therefore, the external WDT 116 resets the sphere information control MPU and the sphere information control I / O port 112 by outputting a reset signal. Thereafter, the sphere information control MPU performs this sphere information control side power-on process from the beginning again. Note that the processing and loop processing in steps S572 to S586 are referred to as “sphere information control power-off processing”.

  The pachinko machine 1 (ball information control MPU) is reset when a power failure occurs or is momentarily stopped, and performs a power-on process on the ball information control side by the subsequent power recovery.

  In step S530, it is checked whether or not the sphere information backup information stored in the sphere information control built-in RAM is normal, and in step S532, the sphere information control unit power-off process is normally terminated. It is inspected whether or not. As described above, the sphere information backup information stored in the sphere information control built-in RAM is checked twice to check whether or not the sphere information backup information is stored by an illegal act.

[Ball information control timer interrupt processing]
Next, the sphere information control side timer interruption process will be described. This sphere information control side timer interruption process is repeatedly performed every interruption period (2 ms in the present embodiment) set in the sphere information control side power-on process shown in FIGS.

  When the sphere information control side timer interrupt process is started, the sphere information control MPU of the sphere information control unit 118 in the sphere information control board 110 sets the timer interrupt to be prohibited and switches registers (see FIG. 22). (Evacuation) is performed (step S590). Here, the general-purpose storage element (general-purpose register) used in the above-described sphere information control unit main process is switched to the auxiliary register. By using this auxiliary register in the sphere information control side timer interrupt process, the value of the general-purpose register is not overwritten. This prevents the contents of the general-purpose register used in the main process on the sphere information control side from being destroyed.

  Subsequent to step S590, the value 1 is set to the 2 ms elapsed flag HT-FLG (step S592). The 2 ms elapsed flag HT-FLG is a flag that counts 2 ms every time the ball information control unit timer interrupt process is performed, that is, every 2 ms. The value is 0 when 2 ms has elapsed and 1 has not elapsed. Respectively. Subsequent to step S592, the register is switched (returned) (step S594). This return is switched from the auxiliary register used in the sphere information control side timer interrupt process to the general-purpose memory element (general-purpose register). By using this general-purpose register in the main process on the sphere information control side, the value of the auxiliary register is not overwritten. This prevents the contents of the auxiliary register used in the ball information control unit timer interrupt processing from being destroyed. Subsequent to step S594, interrupt permission is set (step S596), and this routine ends.

[Each process executed in the sphere information control main process]
Next, each process executed by the sphere information control MPU of the sphere information control board 110 every 2 ms in the sphere information control main process of FIG. 21 will be described. First, the ball lending process will be described, and then the hitting ball availability determination process, the number-of-balls counting process, the ball feeding / launching drive process, the shot-ball detecting process, and the ball-number subtracting process will be described. The hitting / impossible hitting determination process, the number-of-balls counting process, the ball-feeding / firing driving process, the shot-ball detecting process, and the number-of-balls subtracting process are executed as one of the main action setting processes in step S564. The determination process is performed in the order of the determination process for the ball number, the ball count process, the ball feed / fire drive process, the shot ball detection process, and the ball count subtraction process.

  When the player inserts the card 403 into the card insertion slot, the checkout machine 4 detects the insertion of the card 403 and reads the data stored in the card 403 through the card processor 402. That is, the RAM which reads the ID stored in the ID storage unit 404 of the card 403 in FIG. 15, the remaining number stored in the remaining number storage unit 405, and the number of balls held in the ball number storage unit 406 is read into the RAM. Are stored in predetermined storage areas (ID storage area, remaining frequency storage area, and ball count storage area).

  Next, the checkout machine 4 determines whether the inserted card 403 is usable or unusable. In this embodiment, when the read remaining number is 0 and the read number of held balls is 0, it is determined that the card 403 cannot be used, and the card 403 is ejected from the card insertion slot. For this reason, when it is determined that the card 403 is unusable, each of the ball count counting process, the ball feed / firing drive process, and the ball count subtracting process described below is not executed.

  On the other hand, when the read remaining frequency is not 0, or when the read remaining frequency is 0 and the read number of held balls is not 0, the checkout machine 4 determines that the card is usable, and the ball information The card usable information is transmitted to the control board 110.

  When the player presses the ball lending button to perform a game, an operation signal for the ball lending button is input to the settlement machine 4. In response to the operation signal of the ball lending button, the checkout machine 4 performs ball lending processing, for example, transmits a specified number of balls to the ball information control MPU of the ball information control board 110, and thereafter from the ball information control MPU. It waits until it receives the end of the ball rental sent.

[Rental processing]
Here, the lending process executed by the ball information control MPU will be described. FIG. 32 is a flowchart showing a subroutine of a ball lending process performed by the ball information control MPU. The ball lending process is executed as one of the settlement machine communication processes in step S558 executed every 2 ms in the ball information control main process.

  When the ball information control MPU starts the ball lending process, the ball information control MPU determines whether or not the card usable information transmitted from the checkout machine 4 is received (step S600). If the card usable information transmitted from the checkout machine 4 is received in step S600, the process proceeds to step S601, and a ball count counter (a gaming machine possession machine) that is a part of the storage area set in the built-in RAM. (Ball number storage area) is cleared to 0 (step S601), and the process proceeds to step S602. On the other hand, if the card usable information transmitted from the checkout machine 4 is not received in step S600, the process proceeds directly to step S602. Note that the initial value of the holding ball number counter is set to “0” by the power recovery setting in the RAM work area in step S534.

  When proceeding to step S602, the ball information control MPU determines whether or not the number of rented balls transmitted from the settlement machine 4 is received (step S602). If the number of rented balls transmitted from the checkout machine 4 is received in step S602, the process proceeds to step S603, and the received number of lent balls is added to the value of the number of held balls counter (step S603). The end of lending is transmitted to the checkout machine 4 (step S604), and the lending process subroutine is exited.

  On the other hand, if the number of rents transmitted from the checkout machine 4 is not received in step S602, the process does not proceed to step S603 and step S604, and the direct renting process subroutine is exited.

  In this way, card usable information is transmitted to the ball information control board 110 only when a newly usable card 303 is inserted into the checkout machine 4. In addition, the number of balls lent is transmitted to the ball information control MPU only when the operation signal of the ball lending button is input to the checkout machine 4 after the card usable information is received. Then, when the number of rented balls is received, the number of rented balls is first added and stored in the value of the number-of-balls counter.

[Battery ball impossibility determination processing]
Next, the hitting / impossible determination process executed by the ball information control MPU will be described. FIG. 33 is a flowchart showing a subroutine of hitting / impossible hitting determination processing performed by the ball information control MPU. The hit / impossibility determination process is executed as one of the main action setting processes in step S564 executed every 2 ms in the ball information control main process.

  When the ball information control MPU starts the hit / impossibility determination process, the ball information control MPU determines whether or not the number of held balls is 0, that is, whether or not the value of the held ball number counter is 0 (step S710). If it is determined in step S710 that the value of the number-of-balls counter is not 0, that is, if step S710 is determined to be NO, the process proceeds to step S711, and the standby standby ball detection switch 70 (see FIG. 19). ) Is on, that is, whether there is a waiting ball in the ball feeder 28 (step S711).

  If it is determined in step S711 that the firing standby ball detection switch 70 (see FIG. 19) is on, 1 (can be fired) is set in the fireable flag (step S712), and a ball is not permitted determination process. Exit the subroutine. On the other hand, when it is determined in step S710 that the value of the number-of-balls counter is 0, and in step S711, it is determined that the firing standby ball detection switch 70 (see FIG. 19) is not on (off). In this case, the launchable flag is set to 0 (cannot be fired) (step S713), and the subroutine for determining whether or not the ball can be hit is exited.

  Thus, when the value of the possession ball counter is not 0 and there is a waiting ball in the ball feeding device 28, the firing solenoid 13 and the ball feeding solenoid 31 can be driven, and the game area 8 of the game ball is substantially obtained. The game is ready to be played. In addition, when the value of the number-of-balls counter is 0, or when there is no waiting ball in the ball feeder 28, the firing solenoid 13 cannot be driven and the game ball is substantially driven into the game area 8. You are in a state where you cannot play. At the same time, the ball feed solenoid 31 cannot be driven.

[Ball count processing]
Next, a description will be given of the number-of-balls counting process corresponding to the ball information processing during the game assuming that the game is substantially possible. FIG. 34 is a flowchart showing a subroutine for the number-of-balls counting process performed by the ball information control MPU. Note that the number-of-balls counting process is executed as one of the main operation setting processes in step S564 executed every 2 ms in the ball information control main process.

  When the ball information control MPU starts the ball count process, the ball information control MPU determines whether or not there is a prize ball command analyzed in the command analysis process of step S562 (step S720). That is, it is determined whether or not a prize ball command is stored in the received command information storage area. If a prize ball command is stored, step S720 is determined to be present, and the number of prize balls corresponding to the prize ball command stored in the received command information storage area is added to the value of the number-of-balls counter and stored (step S722). ), Exit the subroutine of the number-of-balls counting process. On the other hand, if no prize ball command is stored, step S720 is determined to be none and the subroutine for counting the number of possessed balls is exited.

  For example, when a winning occurs at the winning opening set with the number of winning balls “4”, the number of winning balls “4” is added to the value of the holding ball counter and stored, for example, the number of winning balls “15”. When a winning occurs at the winning opening (large winning opening) set to “15”, the number of winning balls “15” is added and stored in the value of the holding ball counter.

[Ball feed and launch drive processing]
Next, the ball feeding / firing driving process will be described. FIG. 35 to FIG. 36 are flowcharts showing an example of a subroutine of the ball feeding / firing driving process performed by the ball information control MPU. The ball feeding / firing driving process is executed as one of the main operation setting processes in step S564 executed every 2 ms in the ball information control main process.

  FIG. 39 is a time chart showing the drive timing of the ball feed solenoid 31 and the firing solenoid 13. When the ball feed solenoid 31 is turned on, the firing solenoid 13 is turned on when the period A has elapsed, and from the time when the firing solenoid 13 is turned on, the ball feed solenoid 31 is turned off when the time B has elapsed. The firing solenoid 13 is turned off when the period C has elapsed since the solenoid 31 was turned off.

  In this embodiment, the period A is 300 ms, the period B is 30 ms, and the period C is 50 ms. When the ball feed solenoid 31 is turned on, the ball is fed into the launch position (rail portion 332) by the ball feed member 32. That is, the shot ball is detected by the shot ball confirmation switch 36. In the present embodiment, when a game ball stopped at the launch position is detected by the launch ball confirmation switch 36 for a predetermined time (30 ms as the period D), it is determined that there is a launch ball. To do.

  As described above, when the game ball stopped at the launch position by the launch ball confirmation switch 36 is detected for a predetermined time, it is determined that there is a launch ball. The erroneous ball count of the sphere can be eliminated, and the certainty in detecting the shot sphere can be increased.

  When the launch solenoid 13 is turned on, the game ball stopped at the launch position by the launch hammer 30 is launched into the game area 8 and the launch ball confirmation switch 36 is turned off. As a result, the number of balls held is decremented by one.

  When the ball information control MPU starts the ball feeding / firing driving process, it first determines whether or not the fireable flag is 1 (fireable) (step S730). When it is determined that the shot is possible in the hitting ball impossibility determination process described above, the launchable flag is set to 1 (fireable). If it is determined in step S730 that the launchable flag is not 1 (can be fired), that is, if the fireable flag is 0 (cannot be fired), the subroutine of the ball feed / fire drive processing is exited. In this case, the substantial ball feeding / firing driving process is not executed.

  On the other hand, if it is determined in step S730 that the fireable flag is 1 (fireable), the process proceeds to step S731, and it is determined whether or not the processing flag is 0 (step S731).

  Here, the process flag is a flag for identifying whether the sphere information control MPU branches to any of the processes in a later-described ball feed / fire drive process, in other words, control in the ball feed / fire drive. It is a flag for identifying the state, “0” means initial setting, and “1” defines a period from turning on the ball feed solenoid 31 to turning on the firing solenoid 13. Yes, the period from turning on the firing solenoid 13 at “2” to turning off the ball feeding solenoid 31 is defined. After turning off the ball feeding solenoid 31 at “3”, the firing solenoid 13 is turned off. It defines the period until.

  The value of the processing flag is set to 0 when the ball feeding / firing driving process is started. Accordingly, step S731 is determined as YES, the process proceeds to step S732, a timer value corresponding to the period A (see FIG. 39, 300 ms) is set in the timer (step S732), and the ball feed solenoid 31 is turned on (step S733). Then, the processing flag is set to 1 (step S734), and the subroutine of the ball feeding / firing driving process is exited. Note that the timer value set in the timer is decremented by 1 every 2 ms in the timer update process in step S556 of FIG.

  The next processing cycle of the ball feeding / firing drive processing is 2 ms later. As a result of setting the processing flag to 1, in the ball feeding / firing driving process of the next cycle, it is determined as YES in step S730, NO is determined in step S731, and the process proceeds to step S735. In step S735, it is determined whether or not the value of the processing flag is 1 (step S735). In this case, since 1 is set in the process flag, step S735 is determined to be YES, and the process proceeds to step S736 to determine whether or not the timer has expired (step S736). If the timer has not expired, step S736 is determined as NO, and the ball feed / firing drive processing subroutine is exited.

  Hereinafter, based on the value 1 of the processing flag until the timer in which the period A is set expires, step S730 is determined as YES, step S731 is determined as NO, step S735 is determined as YES, step The processing routine for determining NO in S736 is repeated.

  Then, when the timer expires, step S736 is determined as YES, and it is determined that the period A has elapsed, the process proceeds to step S737, and the timer value corresponding to the period B (see FIG. 39, 30 ms) is set in the timer. (Step S737), the firing solenoid 13 is turned on (Step S738), the processing flag is set to 2 (Step S739), and the subroutine of the ball feeding / firing driving process is exited.

  As a result of setting 2 in the processing flag, in the ball feeding / firing driving process of the next cycle, step S730 is determined as YES, step S731 is determined as NO, step S735 is determined as NO, and the process proceeds to step S740. . In step S740, it is determined whether or not the value of the processing flag is 2 (step S740). In this case, since 2 is set in the process flag, step S740 is determined to be YES, and the process proceeds to step S741 to determine whether or not the timer has expired (step S741). If the timer has not expired, step S741 is determined to be NO, and the ball feed / fire drive processing subroutine is exited.

  Hereinafter, based on the value 2 of the processing flag until the timer that sets the period B expires, step S730 is determined as YES, step S731 is determined as NO, step S735 is determined as NO, step The processing routine in which S740 is determined as YES and step S741 is determined as NO is repeated.

  Then, when the timer expires, step S741 is determined as YES, and it is determined that the period B has elapsed, the process proceeds to step S742, and the timer value corresponding to the period C (see FIG. 39, 50 ms) is set in the timer. (Step S742), the ball feed solenoid 31 is turned off (Step S743), the process flag is set to 3 (Step S744), and the subroutine of the ball feed / firing drive process is exited.

  As a result of setting 3 in the processing flag, in the next period of the ball feeding / firing driving process, step S730 is determined as YES, step S731 is determined as NO, step S735 is determined as NO, and step S740 is set as NO. The determination is made, and the process proceeds to step S745. In step S745, it is determined whether the timer has expired (step S745). If the timer has not expired, step S745 is determined to be NO, and the subroutine of ball feed / firing drive processing is exited.

  Hereinafter, based on the value 3 of the processing flag until the timer that sets the period C expires, step S730 is determined as YES, step S731 is determined as NO, step S735 is determined as NO, step The processing routine in which S740 is determined as NO and step S745 is determined as NO is repeated.

  When the timer expires, step S745 is determined to be YES, and it is determined that the period C has elapsed, the process proceeds to step S746, the firing solenoid 13 is turned off (step S746), and the processing flag is set to 0. Returning to the initial value (step S747), the subroutine of the ball feeding / firing driving process is exited.

[Fireball detection processing]
Next, the firing ball detection process will be described. FIG. 37 is a flowchart showing a subroutine of a fired ball detection process performed by the ball information control MPU. The shot ball detection process is executed as one of the main operation setting processes in step S564 executed every 2 ms in the ball information control main process.

  When starting the shot ball detection process, the ball information control MPU first determines whether or not the shot ball check switch 36 is on (step S750). As described above, when the ball feed solenoid 31 is turned on, the ball is fed into the launch position (rail portion 332) by the ball feed member 32. That is, the shot ball is detected by the shot ball confirmation switch 36.

  If it is determined that the firing ball confirmation switch 36 is on, the value of the time counter, which is a counter for measuring the time in the on state, is incremented by 1 (step S751), and the process proceeds to step S753.

  On the other hand, when it is determined that the firing ball confirmation switch 36 is not on, that is, when the firing ball confirmation switch 36 is off, the time counter is set to 0 (step S752), and the process proceeds to step S753.

  In step S753, it is determined whether or not the value of the time counter has reached a predetermined time D (30 ms in this example) (step S753). If the value of the time counter does not reach the predetermined time D set in advance, step S753 is determined as NO and the subroutine for the shot ball detection process is exited.

  Since the shot ball detection process is executed every 2 ms, if the game ball stopped at the launch position by the shot ball confirmation switch 36 is continuously detected for a predetermined time D, the time counter is counted every 2 ms. The value is incremented by 1, and the value of the time counter reaches a predetermined time D (in this example, 30 ms, count value 15). In this case, it is determined as YES in step S753, and it is assumed that a projecting ball has been detected, 1 (with detection) is set in the projecting ball detection flag (step S754), and the subroutine of the projecting ball detection process is exited.

  On the other hand, when noise enters the firing ball confirmation switch 36, the firing ball confirmation switch 36 is turned on instantaneously, but then the firing ball confirmation switch 36 is turned off. Accordingly, since the value of the time counter is set to 0 in response to the turning off of the launch ball confirmation switch 36, the value of the time counter is set to a predetermined time D (30 ms, count value 15 in this example). Never reach.

  As described above, when the game ball stopped at the launch position by the launch ball confirmation switch 36 is detected for a predetermined time, it is determined that there is a launch ball. The erroneous ball count of the sphere can be eliminated, and the certainty in detecting the shot sphere can be increased.

[Number of balls subtracted]
Next, the holding ball number subtraction process will be described. FIG. 38 is a flowchart showing a subroutine of the number-of-balls subtraction process performed by the ball information control MPU. The number-of-balls subtraction process is executed as one of the main operation setting processes in step S564 executed every 2 ms in the ball information control main process.

  When starting the ball number subtraction process, the ball information control MPU first determines whether or not the shot ball detection flag is 1 (detected) (step S760). If it is determined that the shot ball detection flag is not 1 (detected), that is, if step S760 is determined to be NO, the subroutine for the number-of-balls subtraction process is exited. In this case, the number of balls is not subtracted.

  If it is determined in step S760 that the shot ball detection flag is 1 (detected), that is, if step S760 is determined to be YES, the process proceeds to step S761, and is the shot ball check switch 36 turned off? It is determined whether or not (step S761). If it is determined in step S761 that the firing ball confirmation switch 36 is not OFF, that is, if it is determined NO in step S761, the subroutine for subtracting the number of balls is exited.

  As described above, when the launch solenoid 13 is turned on, the game ball stopped at the launch position by the launch hammer 30 is launched into the game area 8 and the launch ball confirmation switch 36 is turned off. As a result, the number of balls held is decremented by one. If it is determined in step S761 that the firing ball confirmation switch 36 is off, that is, if step S761 is determined to be YES, the value of the number-of-balls counter is decremented by 1 (step S762), and the firing ball detection flag is set. 0 (no detection) is set (step S763), and the subroutine for the number-of-balls subtraction process is exited.

  As described above, when a game ball stopped at the launch position is detected by the launch ball confirmation switch 36 for a predetermined time, it is determined that there is a launch ball, and it is determined that there is a launch ball. When the game ball is not detected by the launch ball confirmation switch 36, it is determined that the game ball stopped at the launch position has been launched and the number of possessed balls is reduced by one. When noise enters 36, it is possible to eliminate the erroneous ball count of the fired ball due to noise, and to increase the certainty in detecting the fired ball.
