Description

  The present invention relates to a gaming machine.

  For example, a pachinko machine that is a type of gaming machine may include a symbol display device that displays a plurality of symbols on a display screen. The symbol display device starts a variable display of symbols when a prize is awarded to a predetermined operating port provided in the game area. In addition, a big win lottery is performed at the time of winning a prize at the operating opening, and when winning a big win, a display to that effect is displayed on the symbol display device, and the big winning opening is opened so that a large amount of game balls can be obtained. .

  A ball tank for storing game balls is provided on the back side of the pachinko machine. The spherical tank is substantially box-shaped, and an inclined surface that is gently inclined toward the downstream side is provided on the bottom surface of the spherical tank. An opening for discharging the game ball is provided on the bottom surface of the most downstream portion of the ball tank. Therefore, the game balls stored in the ball tank are guided to the opening by the inclined surface and are guided to the payout device through the tank rail functioning as a guide passage provided below the opening. The guided game ball is temporarily stopped by the payout device. When a game ball wins a winning opening such as a big winning opening provided in the gaming area, the paying device pays out the gaming ball to a ball receiving tray provided on the front side of the gaming machine.

  In recent years, in order to prevent the game from becoming monotonous, the symbol display device or the like tends to increase in size. It is also conceivable to separately provide an accessory device such as a light emitting device above the symbol display device. Such an accessory device is provided so as to protrude rearward from the game board. And the protective cover part surrounding the accessory apparatus and the symbol display apparatus may be provided. As a matter of course, when the accessory device is provided on the upper part of the symbol display device, the protective cover portion protruding from the game board must be increased upward. However, since the tank rail is provided close to the upper side of the symbol display device (protective cover portion), the protective cover portion and the tank rail may interfere if the protective cover portion protrudes upward. . Therefore, it is difficult to provide an accessory device above the symbol display device. For the same reason, an increase in the size of the symbol display device is also limited.

Therefore, by projecting a part of the ball tank to the rear of the gaming machine, a projecting part projecting from the ball tank to the rear of the gaming machine is formed, an opening is provided on the bottom surface of the projecting part, and a tank rail is provided below the opening. A pachinko machine in which the tank rail protrudes backward with respect to the ball tank has been proposed (see, for example, Patent Document 1). By adopting such a configuration, the area between the tank rail and the game board expands. By storing a protective cover in that area, an accessory device can be provided on the top of the symbol display device, It is possible to provide a symbol display device.

It has become. Therefore, for example, when the power supply is turned off in the normal procedure, as in the case of the game hall being closed, the state before the turn-off is stored and retained. It is like that.

  Next, the ball tank 132 and the tank rail 133 will be described in detail with reference to FIGS. FIG. 12 is a plan view of the ball tank 132 and the tank rail 133, and includes a partially cutaway view of the protrusion 155. 13 is a cross-sectional view taken along line AA in FIG. 14 is a cross-sectional view taken along line BB in FIG. 9 for explaining the positional relationship among the ball tank 132, the tank rail 133, the game board 61, the sound lamp control device unit 102, and the accessory device 73. FIG. 15 is a partial plan view of the tank rail 133. FIG. 16 is a front view showing a part of the ball tank 132 and the tank rail 133 cut away.

  First, the ball tank 132 will be described in detail. The ball tank 132 is formed of a synthetic resin and is fixed to the base portion 126 with a fastener such as a screw. Specifically, attachment portions 151 are provided at both ends of the ball tank 132 in the gaming machine width direction, and the attachment portion 151 is provided with a screw hole 152 penetrating the attachment portion 151. The base portion 126 is provided with screw holes communicating with the screw holes 152, and the ball tank 132 is attached to the back pack unit 24 by inserting screws through these screw holes.

  The ball tank 132 includes a bottom portion 153 and a side wall portion 154 provided upright around the bottom portion 153. A game ball is stored in an area surrounded by the bottom 153 and the side wall 154. Specifically, the bottom 153 has a substantially rectangular shape that is long in the gaming machine width direction when viewed from above, and is inclined downward toward one side in the gaming machine width direction and to the rear of the gaming machine. The side wall 154 erected around the bottom 153 includes an upstream side wall 154a disposed on the upstream side of the bottom 153 with respect to the gaming machine width direction, a downstream side wall 154b disposed on the downstream side, and a game The front side wall portion 154c is disposed in front of the gaming machine with respect to the longitudinal direction of the machine, and the rear side wall portion 154d is disposed behind the gaming machine. A game ball is stored in an area surrounded by these four wall portions and the bottom portion 153. Further, the upper ends of these four wall portions are on the same horizontal plane.

  A protrusion 155 is provided in the vicinity of the corner between the downstream side wall 154b and the rear side wall 154d. The protruding portion 155 is formed by protruding a part of the ball tank 132 to the rear of the gaming machine. Specifically, the projecting portion 155 includes a first wall portion 155a formed by offsetting a part of the downstream side of the rear side wall portion 154d toward the rear of the game, and both end portions of the first wall portion 155a and the rear side wall, respectively. A second wall 155b that is disposed in the portion 154d and is orthogonal to the first wall 155a, and a third wall formed by extending the downstream side wall 154b to the first wall 155a to the rear of the gaming machine. Part 155c. The protrusion 155 is provided with an opening 156 for discharging the game ball stored in the ball tank 132 to the tank rail 133. The opening 156 is formed in a substantially rectangular shape along the inner wall surfaces of the first wall 155a, the second wall 155b, and the third wall 155c. The opening 156 occupies almost the entire region below the protrusion 155. The opening 156 is continuously formed with respect to the most downstream portion of the bottom 153 in the ball tank 132. Therefore, the game balls stored in the ball tank 132 are guided to the opening 156 by the downward inclination of the bottom 153 of the ball tank 132. The opening 156 has a size that allows a plurality of game balls to pass therethrough.

  The guidance of the game ball to the opening 156 by the bottom 153 of the ball tank 132 will be described. The bottom portion 153 is formed of a first inclined portion 157 and a second inclined portion 158 that guide the game ball to the opening 156. The first inclined portion 157 is formed from the upstream side wall portion 154a side to the middle of the downstream side wall portion 154b side at the bottom portion 153, and is inclined downward from the upstream side wall portion 154a toward the downstream side wall portion 154b. Therefore, the game ball (position B1 in FIGS. 12 to 14 and 16) on the first inclined portion 157 flows down toward the downstream side wall portion 154b. That is, the game ball is guided to one side in the gaming machine width direction by the first inclined portion 157.

  A second inclined portion 158 is provided on the downstream side of the first inclined portion 157. The second inclined portion 158 is formed continuously with respect to the first inclined portion 157. The second inclined portion 158 occupies a predetermined region near the downstream side wall portion 154b. Specifically, the second inclined portion 158 has a certain width in the gaming machine width direction from the downstream side wall portion 154b in the vicinity of the opening 156. The width is narrower than the width of the opening 156 in the gaming machine width direction. Further, the width of the second inclined portion 158 near the opening 156 in the gaming machine width direction is narrower than the width of the first inclined portion 157 near the opening 156 in the gaming machine width direction. And the 2nd inclination part 158 is formed so that the width | variety of a game machine width direction may spread as it goes to the game machine front from the middle position of the game machine front-back direction. In other words, the width of the second inclined portion 158 in the gaming machine width direction becomes narrower toward the opening 156. In other words, the width in the gaming machine width direction of the first inclined portion 157 provided continuously to the second inclined portion 158 increases toward the rear of the gaming machine. The second inclined portion 158 is inclined downward from the front side wall portion 154c toward the rear side wall portion 154d. Therefore, when the game ball flowing down from the first inclined portion 157 reaches the second inclined portion 158 (position B2 in FIGS. 12 and 14), the game ball on the second inclined portion 158 has the opening 156. It flows down toward the rear of the installed gaming machine. Thereby, the game ball stored in the ball tank 132 flows down to the opening 156 (position B3 in FIGS. 12 to 16). In particular, since the second inclined portion 158 becomes narrower toward the opening 156, the game ball on the second inclined portion 158 is the boundary portion or the downstream side wall portion 154b between the first inclined portion 157 and the second inclined portion 158. Along the opening 156. Further, in the gaming machine width direction, the width of the second inclined portion 158 near the opening 156 is narrower than the width of the opening 156 and is narrower than the width of the first inclined portion 157 near the opening 156. Therefore, in the vicinity of the opening 156, the game balls are more likely to concentrate on the downstream side wall portion 154b side where the second inclined portion 158 is provided than on the second wall portion 155b side where the first inclined portion 157 is provided. Therefore, in the vicinity of the opening 156, the load applied to the game ball on the downstream wall 154b side is larger than the load applied to the game ball on the second wall 155b side. Therefore, the load applied to the game ball on the downstream side wall portion 154b side is likely to be applied to the second wall portion 155b side. In other words, the load applied to the game ball on the downstream side wall 154b side in the vicinity of the opening 156 is easily dispersed. Thereby, clogging of the sphere in the vicinity of the opening 156 can be suppressed.

  The first inclined portion 157 is provided with a convex portion 159 that rectifies the game ball. The convex portion 159 protrudes upward from the first inclined portion 157 to the gaming machine. The convex portion 159 has a certain width in front of the gaming machine from the rear side wall portion 154d, and a plurality of game balls pass between the end portion of the convex portion 159 on the front side of the gaming machine and the front side wall portion 154c. A space that can be made is formed. And the convex part 159 is formed from the rear side wall part 154d to the boundary part vicinity of the 1st inclination part 157 and the 2nd inclination part 158. As shown in FIG. Thereby, the game ball on the first inclined portion 157 flows down to the convex portion 159 or the second inclined portion 158. The game balls stored in the ball tank 132 are prevented from flowing down into the opening 156 as they are along the guiding direction of the first inclined portion 157 by the convex portion 159, and along the guiding direction of the second inclined portion 158. It is designed to flow down. Specifically, the convex portion 159 has a third inclined portion 160 that is inclined opposite to the first inclined portion 157. The third inclined portion 160 is provided at a portion of the convex portion 159 opposite to the opening 156. The width of the convex portion 159 in the gaming machine width direction is formed so as to narrow toward the front of the gaming machine. Correspondingly, the width of the third inclined portion 160 in the gaming machine width direction also advances toward the gaming machine front. It is narrowing according to. When the game ball flowing down from the first inclined portion 157 reaches the third inclined portion 160 (position B4 in FIGS. 12 to 14), the momentum of the game ball is reduced. The game ball with reduced momentum flows down along the third inclined portion 160. The gaming ball then flows down along the boundary between the first inclined portion 157 and the third inclined portion 160 toward the front side and the downstream side of the gaming machine. That is, the game ball stored in the ball tank 132 is prevented from flowing from the first inclined portion 157 to the opening 156 as it is by the convex portion 159, and the flow direction is changed to the front side of the gaming machine. Therefore, an excessive load is not applied to the game ball near the opening 156. Then, the game ball whose direction of flow is changed by the convex portion 159 flows down to the front side of the gaming machine of the convex portion 159. That is, the game ball on the first inclined portion 157 flows down so as to bypass the convex portion 159. And since the game ball which flowed down the game machine front side of the convex part 159 flows into the opening part 156 after colliding with the downstream side wall part 154b, the momentum of the game ball flowing down to the opening part 156 is reduced. Thereby, the game ball flows down to the opening 156 from a certain direction and in a stable state. That is, the game ball stored in the ball tank 132 is rectified by the convex portion 159. In addition, the site | part by the side of the opening part 156 of the convex part 159 is formed by extending a part of 2nd wall part 155b in the protrusion part 155 ahead of a game machine. Since the game ball between the convex portion 159 and the downstream side wall portion 154b flows down along the wall portions on both sides, the game ball is smoothly guided to the opening portion 156.

  From the above, the game balls stored in the ball tank 132 are guided to the second inclined portion 158 by the first inclined portion 157 while the direct flow to the opening portion 156 is suppressed by the convex portion 159. Then, the game ball on the second inclined portion 158 is guided to the rear of the gaming machine provided with the opening 156 by the inclination of the second inclined portion 158. The game balls discharged from the ball tank 132 through the opening 156 are received by the tank rail 133 disposed below the opening 156 and guided toward the payout device 135. Since the ball tank 132 is formed of a synthetic resin, the weight of the ball tank 132 can be reduced, and the protrusion 155 and the bottom 153 provided on the ball tank 132 can be easily molded. However, the present invention is not limited to this, and may be made of metal such as aluminum.

  Next, the tank rail 133 will be described. The tank rail 133 is disposed below the protruding portion 155 where the opening 156 is disposed. As shown in FIGS. 11 and 14, the protruding portion 155 is provided so as to protrude rearward of the gaming machine with respect to the ball tank 132, so that the tank rail 133 disposed corresponding thereto is also rearward of the ball tank 132. Protruding to Therefore, the distance between the tank rail 133 and the game board 61 is expanded by the amount of protrusion of the tank rail 133. Therefore, the accessory device 73 can be disposed between the tank rail 133 and the game board 61.

  The tank rail 133 is formed of a synthetic resin and has a long bowl shape opened upward. The tank rail 133 is arranged with the gaming machine width direction as a longitudinal direction, and is inclined downward toward the payout device 135. The guiding direction of the tank rail 133 is formed to be opposite to the guiding direction of the first inclined portion 157 in the sphere tank 132. On the upstream side of the tank rail 133, a ball receiving portion 171 for receiving a game ball discharged from the ball tank 132 through the opening 156 is provided. As shown in FIG. 16, the ball receiving portion 171 has a spherical bottom surface and is disposed below the opening 156. The game ball discharged from the ball tank 132 through the opening 156 is received by the ball receiver 171 and flows down into the tank rail 133 (position B5 in FIGS. 15 and 16). The game balls are divided into two hands by a partition wall 172 provided in the tank rail 133. That is, the game balls are aligned in two rows within the tank rail 133. The game ball is guided toward the payout device 135 along the inclination of the tank rail 133. That is, the game balls stored in the ball tank 132 flow down to one side in the game machine width direction, the flow direction is changed near the opening 156, and to the other in the game machine width direction, which is the guiding direction of the tank rail 133. Flow down. More specifically, the game ball flowing down toward one side in the gaming machine width direction by the first inclined portion 157 is directed toward the rear of the gaming machine along the downstream side wall portion 154b and the third wall portion 155c by the second inclined portion 158. Flow down. Thereafter, the flow direction in the vicinity of the opening 156 is changed from the direction along the third wall portion 155c to the other in the gaming machine width direction, which is the direction opposite to the flow direction of the first inclined portion 157 in the ball tank 132. The game ball then flows down in the tank rail 133 toward the payout device 135. Further, a hole 173 for dropping dust is provided at the bottom of the tank rail 133. The hole 173 prevents dust in the air from collecting on the bottom of the tank rail 133.

  Next, a ball clogging suppression structure near the opening 156 will be described with reference to FIGS. 17 and 18. FIG. 17 is a cross-sectional view taken along the line CC in FIG. 12 for explaining the ball clogging suppression structure, and FIG. 18 is a cutaway view of the ball tank 132 and the tank rail 133 for explaining the ball clogging suppression structure. FIG.

  As described above, the game balls stored in the ball tank 132 by the bottom 153 of the ball tank 132 flow into the opening 156. In addition, since the game ball is temporarily stopped by the payout device 135, the game ball may continue into the ball tank 132 in some cases. In such a case, there is a possibility that the ball clogging may occur due to the game balls continuously stacked in the vicinity of the opening 156. Further, in the vicinity of the opening 156, the flow direction of the game ball is changed from the direction along the third wall portion 155c to the game machine width direction guided by the tank rail 133. When such a change in the flow direction is not smoothly performed, there is a possibility that a ball clogging may occur. For these, a ball clogging suppression structure is provided. As this ball clogging suppression structure, a first ball clogging suppression structure and a second ball clogging suppression structure are provided.

  First, the first ball clogging suppression structure will be described. At a position spaced upward from the opening 156, a restricting portion 181 for restricting continuous stacking of game balls to a predetermined level is provided. The restricting portion 181 is located on the front side of the gaming machine from the predetermined height position above the opening 156 (a position above the opening 156 by a distance X1 with respect to the up-down direction of the gaming machine) to the upper end of the first wall 155a. It is formed by offsetting. Corresponding to the offset, the position of the end portion from the predetermined height position above the opening 156 to the upper end portion of the second wall portion 155b and the third wall portion 155c on the rear side of the gaming machine is a game. Moving to the front side of the aircraft. Then, both end portions of the restricting portion 181 in the gaming machine width direction are respectively disposed at these end portions. In addition, the upper end of the second wall 155b on the rear side of the gaming machine relative to the restricting portion 181 and the upper end of the third wall 155c on the rear side of the gaming machine from the restricting portion 181 are respectively set at predetermined height positions above the opening 156. It is in the same horizontal plane. Between the lower end of the restricting portion 181 and the opening 156, there is a gap of a distance X1 with respect to the vertical direction of the gaming machine. The upper end of the restricting portion 181 and the upper end of the side wall portion 154 of the ball tank 132 are on the same horizontal plane. The restricting portion 181 has an abutment surface 182 that abuts against a game ball on the upstream side of itself. The contact surface 182 is a flat surface and extends in the up-down direction of the gaming machine. In other words, the contact surface 182 is orthogonal to the longitudinal direction of the gaming machine, which is the direction in which the gaming ball flows in the vicinity of the opening 156. Since the game ball flowing into the opening 156 is restricted from moving downstream from the restricting portion 181 by being in contact with the contact surface 182, at least a part of the space above the opening 156 from the opening 156. Also, the continuous stacking of game balls upward is restricted to a predetermined level. Specifically, among the game balls that flow into the opening 156, the game ball that is above the lower end of the restricting portion 181 contacts the contact surface 182 of the restricting portion 181. This restricts the movement of the game ball to the rear side of the gaming machine, which is downstream of the restricting portion 181 (position B6 in FIG. 17). On the other hand, the game ball between the lower end of the restricting portion 181 and the bottom 153 and the opening 156 of the ball tank 132 flows down toward the opening 156 without being restricted by the restricting portion 181. . Therefore, on the rear side of the gaming machine with respect to the restricting portion 181, the continuous stack of game balls is restricted to the lower end portion of the restricting portion 181. Therefore, the load of the game ball applied to the game ball (position B7 in FIG. 17) existing near the opening 156 is reduced as a whole because the load received from above the game ball is reduced. Thereby, clogging of the sphere in the vicinity of the opening 156 can be suppressed. When the load applied to the game ball near the opening 156 is reduced, the load applied to the game ball discharged from the ball tank 132 through the opening 156 and flowing down in the tank rail 133 is also reduced. Therefore, clogging of the balls in the tank rail 133 can be suppressed. The game ball whose movement is restricted falls along the contact surface 182, passes between the lower end of the restriction part 181 and the opening part 156, and flows into the opening part 156. Further, the distance X1 from the opening 156 to the lower end of the restricting portion 181 may be equal to or larger than the diameter R of the game ball so that at least one game ball can pass. In addition, the contact surface 182 is a flat surface, but is not limited thereto, and may be a curved surface or an uneven surface.

  The restricting portion 181 is arranged such that the distance X2 in the front-rear direction of the gaming machine from the end portion of the restricting portion 181 on the front side of the gaming machine to the end portion of the opening 156 on the front side of the gaming machine is less than the diameter R of the game ball. ing. As a result, at least a part of the load of the game ball (position B6 in FIG. 17) whose movement is regulated by the regulation unit 181 is applied to the bottom 153 of the ball tank 132, so that all of the load is near the opening 156. It is suppressed that it is applied to the game ball (position B7 in FIG. 17). Therefore, it is possible to suppress the decrease in the capacity of the ball tank 132 due to the provision of the restricting portion 181 as much as possible while suppressing the clogging of the ball near the opening 156.

  In addition, the distance between the opening 156 and the lower end of the restricting portion 181 is such that the game balls can pass through the number of alignment of the tank rail 133 and more than the number of alignment can not pass. The positional relationship between the opening 156 and the restricting portion 181 is set. Specifically, when the restricting portion 181 is provided above the opening 156, the distance between the gaming machine front side end of the opening 156 and the lower end of the restricting portion 181 is the number of game balls aligned by the number of tank rails 133 aligned. Can be passed, and the gaming machine up and down distance X1 from the opening 156 to the lower end of the restricting portion 181 and the gaming machine of the restricting portion 181 so that the number of game balls larger than the number of alignment can not pass through A distance X2 in the longitudinal direction of the gaming machine from the end on the front side to the end on the front side of the gaming machine of the opening 156 is set. However, since X2 is preferably less than one game ball as described above, X2 is set within the range. As a result, the number of stacked game balls that can flow into the opening 156 at a time is equal to the number of game balls aligned in the tank rail 133. That is, the game ball easily flows into the tank rail 133 in a state where the number of stacks is equal to the number of alignment of the tank rails 133 by passing between the opening 156 and the restricting portion 181. Therefore, since it is easy to flow down smoothly in the tank rail 133, the ball clogging in the tank rail 133 can be suppressed.

  A support wall portion 183 that supports the restriction portion 181 is provided between the restriction portion 181 and the first wall portion 155a. The support wall portion 183 is orthogonal to the first wall portion 155a and the restriction portion 181. The restricting portion 181 and the protruding portion 155 are integrally formed via the support wall portion 183. Specifically, one end portion of the support wall portion 183 in the longitudinal direction of the gaming machine is disposed at the lower end portion of the restriction portion 181 and the other end portion is disposed at the upper end portion of the first wall portion 155a. The restricting portion 181 is supported by the support wall portion 183 with respect to the protruding portion 155. Therefore, since the strength of the restricting portion 181 is increased, the restricting portion 181 is not easily bent even if the game ball comes into contact with the restricting portion 181. Thereby, the clogging of the ball | bowl by the bending of the control part 181 can be suppressed.

  Further, the support wall portion 183 extends along the gaming machine width direction, and both end portions of the support wall portion 183 are respectively connected to the upper end portion on the rear side of the gaming machine from the restriction portion 181 of the second wall portion 155b and the third wall. It is arrange | positioned from the control part 181 of the part 155c at the upper end part of the game machine back side. Therefore, the support wall 183 covers the entire space in the space above the opening 156 with respect to the gaming machine width direction, and covers the restriction wall 181 to the first wall 155a in the longitudinal direction of the gaming machine. Is formed. Therefore, the game balls are stacked in the lower region of the support wall portion 183, and the game balls are not stacked above the support wall portion 183. In other words, below the support wall portion 183, the level (height) of continuous stacking of the game balls is restricted to the support wall portion 183 (the height at which the support wall portion 183 is provided). Therefore, the clogging of the sphere near the opening 156 can be more suitably suppressed. Further, the support wall 183 makes it difficult for dust in the air to enter the opening 156. Therefore, it is possible to suppress clogging of the balls due to dust.

  Next, the second ball clogging suppression structure will be described with reference to FIGS.

  The protrusion 155 has a first curved surface 184 that is curved at a curvature smaller than the curvature of the game ball at the boundary between the inner wall surface of the first wall portion 155a and the inner wall surface of the third wall portion 155c. Yes. By the first curved surface 184, the inner wall surface of the first wall portion 155a and the inner wall surface of the third wall portion 155c are continuously connected. In other words, rounded corners are formed at the corners where the inner wall surface of the first wall portion 155a and the inner wall surface of the third wall portion 155c are connected. Corresponding to the first curved surface 184, the opening 156 formed along the inner wall surfaces of the first wall portion 155a and the third wall portion 155c is also curved. A second curved surface 185 that is curved with a curvature smaller than the curvature of the game ball is also provided at a portion of the tank rail 133 that is located below the first curved surface 184. Specifically, the second curved surface 185 is provided on the rear side of the gaming machine at the upstream end of the ball receiving portion 171. The second curved surface 185 has the same curvature as the first curved surface 184. In other words, a curved surface having a curvature smaller than the curvature of the game ball is formed substantially continuously from the bottom of the tank rail 133 including the opening 156 to the upper end of the protrusion 155. By the first curved surface 184 and the second curved surface 185, the flow direction of the game ball is smoothly changed from the direction along the third wall portion 155c to the game machine width direction guided by the tank rail 133. Specifically, the game ball (position B3 in FIGS. 15 and 16) flowing down along the downstream side wall 154b and the third wall 155c by the second inclined portion 158 is the first curved surface 184 or the second It reaches the curved surface 185 and smoothly flows down from the third wall portion 155c side to the first wall portion 155a side along these curved surfaces. Since the first wall portion 155a extends along the gaming machine width direction, the direction along the first wall portion 155a and the guiding direction of the tank rail 133 substantially coincide. Therefore, the flow direction of the game ball is smoothly changed to the guiding direction of the tank rail 133. In other words, it is difficult for game balls to accumulate at a corner portion between the inner wall surface of the first wall portion 155a and the inner wall surface of the third wall portion 155c or a portion corresponding to the corner portion of the tank rail 133. Therefore, it is possible to suppress the clogging of the balls due to the change in the flow direction.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 19, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  A main control board 311 provided in the main controller 107 incorporates a main control circuit 312 and a power failure monitoring circuit 313. The main control circuit 312 is equipped with a CPU 321. The CPU 321 includes a ROM 322 storing various control programs executed by the CPU 321 and fixed value data, and a memory for temporarily storing various data when the control program stored in the ROM 322 is executed. A certain RAM 323 and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit are incorporated.

  The RAM 323 is configured to retain data by supplying data storage holding power from the power supply and launch control board 331 provided in the power supply and launch control device 147 even after the pachinko machine 10 is powered off.

  An input / output port is connected to the CPU 321 via a bus line including an address bus and a data bus. Connected to the input side of the main control circuit 312 are a power failure monitoring circuit 313 provided on the main control board 311, a payout control board 332 provided on the payout control device 146, and other switches not shown. In this case, a power supply and launch control board 331 is connected to the power failure monitoring circuit 313, and power is supplied to the main control circuit 312 via the power failure monitoring circuit 313.

  On the other hand, a power failure monitoring circuit 313, a payout control board 332 and a relay terminal board 333 are connected to the output side of the main control circuit 312. Various commands such as a prize ball command are output to the payout control board 332. Various commands and the like are output from the main control circuit 312 to the sound lamp control board 334 provided in the sound lamp control device 103 via the relay terminal plate 333.

  The power failure monitoring circuit 313 relays the main control circuit 312 and the power source and launch control board 331, and monitors the DC stable 24 volt power source that is the maximum power source output from the power source and launch control board 331.

  The payout control board 332 performs payout control of prize balls and rental balls by the payout device 135. The CPU 341 that is an arithmetic unit includes a ROM 342 that stores a control program executed by the CPU 341, fixed value data, and the like, and a RAM 343 that is used as a work memory or the like. The game balls replenished to the ball tank 132 from the island facility flow down to the tank rail 133 through the opening 156 and are temporarily stopped by the payout device 135 provided in the middle of the vertical passage unit 134. Then, the game balls that have been stopped are paid out toward the upper plate 95a and the lower plate 96a provided on the downstream side of the vertical passage unit 134 based on various payout commands from the payout control board 332.

  Similar to the RAM 323 of the main control circuit 312, the RAM 343 of the payout control board 332 is configured to retain data by supplying data storage holding power from the power supply and launch control board 331 even after the power of the pachinko machine 10 is shut off. It has become.

  An input / output port is connected to the CPU 341 of the payout control board 332 through a bus line including an address bus and a data bus. A main control circuit 312, a power and launch control board 331, and a backpack board 136 are connected to the input side of the payout control board 332. Further, the main control circuit 312 and the back pack board 136 are connected to the output side of the payout control board 332.

  The power supply and launch control board 331 includes a power supply unit and a launch control unit. The power supply unit supplies necessary operating power to each of the main control circuit 312 and the payout control board 332 through a path indicated by a double line arrow. The launch control unit is responsible for launch control of the game ball launch mechanism 80 in accordance with the operation of the game ball launch handle 84 by the player, and the game ball launch mechanism 80 is driven when predetermined launch conditions are met. .

  The sound lamp control board 334 controls the accessory device 73, the annular illumination unit 92, the error display lamp unit 93, the speaker unit 94, and the display control device 101. The CPU 351, which is an arithmetic device, includes a ROM 352 that stores a control program executed by the CPU 351, fixed value data, and the like, and a RAM 353 that is used as a work memory or the like.

  An input / output port is connected to the CPU 351 of the sound lamp control board 334 via a bus line including an address bus and a data bus. A main control circuit 312 is connected to the input side of the sound lamp control board 334 by being relayed to the relay terminal plate 333. Based on various commands output from the main control circuit 312, the accessory device 73, the annular illumination Unit 92, error display lamp unit 93, speaker unit 94, and display control device 101. In particular, since the accessory device 73 can move in the front-rear direction with respect to the gaming machine, a dynamic effect can be performed. The display control device 101 controls the symbol display device 71 based on a display command input from the sound lamp control board 334.

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

  A protruding portion 155 is formed by protruding a part of the ball tank 132 toward the rear of the gaming machine, and an opening 156 is provided in the protruding portion 155. A restricting portion 181 is provided that restricts the continuous stacking of game balls above the opening 156 to a predetermined level in at least a part of the space above the opening 156. Thereby, since the load applied to the game ball in the vicinity of the opening 156 is reduced, clogging of the ball in the vicinity of the opening 156 can be suppressed.

  Specifically, the restricting portion 181 is arranged so as to be spaced upward from the opening 156, and a game ball from the restricting portion 181 to the downstream side is brought into contact with a game ball from the upstream side of the restricting portion 181, thereby playing the game downstream. A contact surface 182 that restricts the movement of the sphere is provided. Thereby, on the downstream side of the restricting portion 181, the continuous stacking of game balls is restricted to a predetermined level. Therefore, clogging of the spheres in the vicinity of the opening 156 can be suppressed.

  Further, since the game balls stored in the ball tank 132 pass between the lower end of the restricting portion 181 and the opening 156 and flow into the opening 156, the interval between the lower end of the restricting portion 181 and the opening 156 is adjusted. By doing so, the amount of game balls flowing into the tank rail 133 at a time can be adjusted. Therefore, by adjusting the interval, ball clogging caused by excessive game balls can be suppressed on the tank rail 133 and the downstream side thereof.

  The restricting portion 181 is formed by offsetting a part of the first wall portion 155a to the front side of the gaming machine. Therefore, a part of the first wall portion 155 a in the protruding portion 155 is also used as the restricting portion 181. Thereby, compared with the structure which provides the control part 181 independently, simplification of a structure is achieved.

  The upper end of the restricting portion 181 and the upper end of the side wall portion 154 of the ball tank 132 are on the same horizontal plane. Usually, since the ball tank 132 stores game balls in an area surrounded by the side wall portion 154 and the bottom portion 153, the game balls are unlikely to be stacked beyond the upper end of the side wall portion 154. Therefore, the height at which the game balls can be stacked in the ball tank 132 is substantially the same as the height at which the restricting portion 181 can restrict the movement of the game balls. Therefore, it is possible to prevent the stacked game balls from exceeding the restricting portion 181.

  The restriction portion 181 may be bent by contact with the game ball. When the restricting portion 181 is bent, the movement of the game ball may not be restricted. On the other hand, since the restricting portion 181 and the protruding portion 155 are integrally formed via the support wall portion 183, the restricting portion 181 is supported by the protruding portion 155 via the support wall portion 183. Therefore, the strength required for the restricting portion 181 can be easily secured, and the bending deformation of the restricting portion 181 can be suitably suppressed. Therefore, it is possible to suppress the clogging of the balls due to the bending of the restricting portion 181.

  Further, the support wall portion 183 is formed so as to cover the entire space with respect to the gaming machine width direction in the space above the opening 156 and the restriction wall 181 to the first wall portion 155a in the longitudinal direction of the gaming machine. Has been. Accordingly, the level of continuous stacking of the game balls is restricted to the support wall 183 below the support wall 183. Therefore, the clogging of the sphere near the opening 156 can be more suitably suppressed.

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

  (A) In the above-described embodiment, the restriction unit that restricts the movement of the game ball is provided, but the invention is not limited thereto. For example, a configuration as shown in FIG. FIG. 20 is a view showing a modification of the restricting portion based on FIG.

  (A-1) In the configuration shown in FIG. 20, a roof portion 191 that covers at least a part of the space above the opening 156 is provided at a predetermined height position above the opening 156. The roof portion 191 is provided so as to protrude from the first wall portion 155a to the front side of the gaming machine. The roof portion 191 is formed from the second wall portion 155b to the third wall portion 155c. That is, the roof portion 191 covers the entire space above the opening 156 in the gaming machine width direction. The roof portion 191 has an upper surface 192 that receives the game ball. The game ball above the roof portion 191 is received by the upper surface 192 of the roof portion 191. Therefore, the continuous stacking of the game balls above the roof portion 191 is restricted. Therefore, the clogging of the sphere near the opening 156 can be suppressed. Further, the decrease in the amount of storage of the ball tank 132 due to the provision of the roof portion 191 is reduced as compared with the case where the restriction portion 181 is provided. Note that the end portion of the roof portion 191 on the front side of the gaming machine may be damaged by an impact when contacting the game ball, and thus it is preferable to chamfer a curved surface. In addition, the end of the roof 191 on the front side of the gaming machine is disposed on the rear side of the gaming machine with respect to the end of the opening 156 on the front side of the gaming machine, and the end of the roof 191 on the front side of the gaming machine The distance X3 in the front-rear direction of the gaming machine with respect to the end of the opening 156 on the front side of the gaming machine is preferably less than one gaming ball.

  (A-2) Moreover, in FIG. 20, the upper surface 192 which receives a ball | bowl is formed so that it may become a downward slope toward the front of a game machine from the 1st wall part 155a. With this configuration, the game ball received on the upper surface 192 flows down toward the front of the gaming machine, falls down from the roof portion 191, and flows down toward the opening 156. That is, the game ball received by the upper surface 192 is guided to the opening 156.

  (B) The modification of the control part which controls the movement of the game ball detailed in the said embodiment below is shown. (A)-(d) of FIG. 21 is principal part sectional drawing which roughly shows the modification of the control part 181 shown by FIG.

  (B-1) In the above embodiment, the contact surface 182 is orthogonal to the longitudinal direction of the gaming machine, but is not limited thereto, and may be inclined to either direction relative to the longitudinal direction of the gaming machine. . Moreover, you may incline in either with respect to the game machine width direction. In short, any plane that intersects with the longitudinal direction of the gaming machine, which is the direction in which the game ball flows down, may be used. For example, in FIG. 21A, a restricting portion 193 that is inclined downward toward the opening 156 is provided. Thereby, the contact surface 194 of the restricting portion 193 is similarly inclined toward the opening 156. Since the game ball whose movement is restricted flows down along the contact surface 194, the game ball is guided to the opening 156.

  (B-2) In the above embodiment, the restricting portion 181 is provided above the opening 156, but may be provided on the front side of the gaming machine from the opening 156. For example, in FIG. 21B, a restricting portion 195 is provided above the bottom portion 153 of the ball tank 132. In such a case, the support wall portion 196 also extends forward of the gaming machine corresponding to the position of the restriction portion 195. Further, since a gap is formed between the restricting portion 195 and the rear side wall portion 154d of the ball tank 132, there is a possibility that the game ball falls from the ball tank 132 through the gap. Therefore, in order to prevent such inconvenience, it is necessary to provide the second wall portion 197 between the restricting portion 195 and the rear side wall portion 154d. However, the case where it is provided above the opening 156 is superior to the case where it is provided above the bottom 153 in terms of the storage amount of the ball tank 132.

  (B-3) In the above embodiment, the restricting portion 181 is formed by offsetting a part of the first wall portion 155a to the front of the gaming machine, but is not limited thereto. For example, a restriction unit may be provided separately. Further, as shown in FIG. 21 (c), a support wall 199 may be provided on the restriction 198 provided separately. In this case, the ball receiving region 200 surrounded by the restricting portion 198, the first wall portion 155a, the second wall portion 155b, and the third wall portion 155c is formed with the support wall portion 199 as a bottom portion. Since the ball receiving area 200 is large enough to store a game ball, even if the game ball may flow into the opening 156 beyond the restriction portion 198, the game ball is a ball. It is captured in the receiving area 200. Therefore, the game ball is prevented from falling from the ball tank 132.

  (B-4) In the above embodiment, the restricting portion 181 and the protruding portion 155 are integrally formed, but this may be changed. For example, in FIG. 21D, the restricting portion 201 is detachably attached to the protruding portion 155 via the support wall portion 202. Specifically, one end portion of the support wall portion 202 is disposed at the upper end portion of the restriction portion 201. And the other end part of the support wall part 202 and the attaching part 203 provided in the upper end part of the 1st wall part 155a are being fixed with the screw | thread 204. FIG. Since the restricting portion 201 can be easily removed by removing the screw 204, the restricting portion 201 is detachably attached. In this configuration, it is preferable to use a transparent resin for the restricting portion 201 and the support wall portion 202. Thereby, the state near the opening 156 can be easily confirmed.

  (C) In the said embodiment, although the support wall part 183 is arrange | positioned at the lower end part of the control part 181, it is not restricted to this. For example, the support wall portion 183 may be inclined upward from the upper end portion of the first wall portion 155a toward the front of the gaming machine, and may be disposed at the upper end portion of the restricting portion 181. Moreover, in the said embodiment, although the support wall part 183 is orthogonally crossed with respect to the control part 181 and the 1st wall part 155a, the support wall part 183 may be inclined and may be curved. The point is that, similarly to the positional relationship between the lower end portion of the restricting portion 181 and the opening portion 156, the distance between the opening portion 156 and the support wall portion 183 can pass game balls as many as the number of alignment of the tank rail 133, and the alignment. The positional relationship between the opening 156 and the support wall 183 may be set so that a game ball more than a few minutes of game balls cannot pass. Specifically, since the support wall portion 183 is provided above the opening portion 156, the distance between the gaming machine front side end portion of the opening portion 156 and the support wall portion 183 is equal to the number of alignment of the tank rails 133. It is only necessary that the support wall portion 183 be formed so that the game ball can pass and more game balls cannot pass. For example, when the alignment number of the tank rails 133 is two rows, the distance between the game machine front side end portion of the opening 156 and the support wall portion 183 may be two or more game balls and less than three. However, when the support wall 183 and the first wall 155a are orthogonal, the support wall 183 and the support wall 183 are more curved than when the support wall 183 is curved while securing the distance. Since the space is formed at the corner with the first wall portion 155a, it is excellent in that a clearance space can be secured when the game ball changes its direction toward the tank rail 133.

  (D) In the above embodiment, the first curved surface 184 and the second curved surface 185 are formed so as to have the same curvature. However, the present invention is not limited to this, and even if both are formed with different curvatures. Good. However, when the curvatures of the two are the same, no step is formed at the boundary between the two, so that the game ball flows easily.

  (E) In the above embodiment, the accessory device 73 is provided on the upper portion of the center frame 72, but the present invention is not limited to this. For example, the accessory device 73 is not provided, and a large symbol display device may be arranged instead of the symbol display device 71. In such a case, a part of the large symbol display device and its control device is disposed between the game board 61 and the tank rail 133.

  (F) In the above embodiment, the opening 156 is formed along the inner wall surfaces of the first wall 155a, the second wall 155b, and the third wall 155c, but is not limited thereto. For example, the protrusion 155 may be provided with a bottom continuous with the most downstream portion of the bottom 153 of the ball tank 132, and a part of the bottom may be opened. Further, the opening 156 is not limited to a rectangle but may be a circle. In short, it is only necessary to have a size that allows at least one game ball to pass.

  (G) In the above embodiment, the opening 156 is provided in the protrusion 155, but the present invention is not limited to this. For example, at least a part of the opening 156 may be provided in the bottom 153 of the ball tank 132. . In such a case, since the tank rail 133 is disposed below the opening 156, at least a part of the tank rail 133 is disposed below the ball tank 132.

  (H) In the above embodiment, the guiding direction of the tank rail 133 is the gaming machine width direction, but is not limited thereto. Further, the guiding directions of the ball tank 132 and the tank rail 133 are different from each other. However, the guiding direction is not limited to this, and may be the same direction.

  (I) The present invention can also be applied to other types of ball and ball game machines different from the above embodiments, for example, game machines such as pachinko machines, arrange ball machines, and sparrow balls provided with other objects.

  In addition, a pachinko machine and a slot machine that have a take-in device and start rotation of a reel by operating a start lever after a predetermined number of game balls stored in the storage unit are taken in by the take-in device The present invention can also be applied to a gaming machine in which is integrated.
