Moreover, in this embodiment, the display mode of the special symbols in the first special symbol display device 40 and the second special symbol display device 41 is not the same. That is, even if the same type of jackpot, the display mode of the special symbol in the first special symbol display device 40 and the display mode of the special symbol in the second special symbol display device 41 are different. In this case, even if the player learns the display mode of one of the special symbol display devices 40 and 41, the type of jackpot or the like cannot be grasped from the other display mode. The effect that the display mode of a symbol can be obscure is acquired. If a plurality of LEDs are turned on even in the case of a loss, it is also possible to make it difficult to determine whether it is a loss or a big hit.

  The normal symbol display device 42 is for notifying the lottery result of the lottery performed when the game ball passes through the normal symbol gate 33 as an opportunity. When the winning lottery is won, the normal symbol display device 42 composed of LEDs is turned on, and then the second start port 31 is controlled to the second mode for a predetermined time. Note that this normal symbol also does not immediately notify the lottery result when the game ball passes through the normal symbol gate 33, and the normal symbol display device 42 blinks until a predetermined time elapses. Is displayed in a variable manner. That is, the normal symbol display device 42 blinks until a predetermined time elapses. The blinking of the normal symbol display device 42 constitutes a normal symbol variation display, and the lighting of the normal symbol display device 42 constitutes a normal symbol stop display corresponding to the lottery result of the winning lottery.

By the way, even if a game ball enters the start opening 30 or 31 during the special symbol variation display or during the special game in which the special prize opening / closing device is operated, the special symbol variation display is immediately performed and the special prize lottery is performed. When the lottery result is not notified, the special symbol change display (notification of the lottery result of the special prize lottery) is suspended under certain conditions. In more detail, the right to display the change of the special symbol in which the game ball enters and is reserved at the first start opening 30 is reserved as the first hold (U1), and the game ball enters the second start opening 31. The right of variable display of the special symbol reserved is reserved as the second reservation (U2).
For both of these holds, the upper limit reserved number is set to four, and the reserved number is displayed on the first hold indicator 43 and the second hold indicator 44, respectively. When there is one first hold (U1), the LED on the left side of the first hold indicator 43 is lit, and when there are two first holds (U1), 2 of the first hold indicator 43 is displayed. One LED lights up. In addition, when there are three first holds (U1), the left LED of the first hold indicator 43 blinks and the right LED is lit. When there are four first holds (U1), Two LEDs of the 1 hold indicator 22 blink. Further, on the second hold indicator 44, the reserved number of the second hold (U2) is displayed in the same manner as described above.

On the other hand, the upper limit reserved number is similarly set to 4 for the variable symbol display, and the reserved number is the same as that of the first special symbol hold display device 43 and the second special symbol hold display device 44. It is displayed on the normal symbol hold display device 45 depending on the mode.
The high-probability state display device 46 is composed of LEDs, and lights up under the condition that a high-probability state, which will be described later, is in the morning (when power is restored) before turning off the power. On the other hand, the short-time state display device 47 is also composed of LEDs, but this is lit not only at the time of wake-up but also when the power is turned on under the condition that it is in the short-time state.

The payout control board 103 includes a payout CPU 103a, a payout ROM 103b, and a payout RAM 103c, and is connected to the main control board 101 so as to be capable of two-way communication. The payout CPU 103a reads out the program stored in the payout ROM 103b based on the input signal from the payout ball counting switch 32 and the timer for detecting whether or not the game ball has been paid out, and performs arithmetic processing. Based on this, the corresponding data is transmitted to the main control board 101. The payout control board 103 is connected to a payout motor 31 of a prize ball payout device for paying out a predetermined number of prize balls from the game ball storage unit to the player. The payout CPU 103a reads out a predetermined program from the payout ROM 103b based on the payout number designation command transmitted from the main control board 101, performs arithmetic processing, and controls the prize ball payout device 26 to play a predetermined prize ball. Pay to the person. At this time, the payout RAM 103c functions as a data work area during the calculation process of the payout CPU 103a.

  As shown in FIGS. 5 to 9, the pachinko launching device 200 includes a rotor 201 made of a magnetic body having a shaft 201 that forms a rotor axis and three arm portions 202, 203, and 204 within an angle range of approximately 180 °. And an E-shaped three-pole stator 206 that generates a magnetic field attracting each of the three arm portions 202, 203, 204, a coil 208 wound around a central core 207 of the stator 206, and rotation of the rotor 205 And a hammer 209 fixed to a shaft 201 which is a shaft. The shaft 201, the rotor 205, the stator 206, and the coil 208 constitute a rotary solenoid to form a firing solenoid 10a. The angle formed by each of the three arm portions is preferably approximately 90 °.

  The shaft 201 is provided with a D-cut 210 and is fitted with a D-cut 211 provided on a hammer 209 attached to the shaft 201. Further, the D cut 212 is fitted with a D cut 213 formed on the rotor 205. The hammer 209 is substantially L-shaped, and when one of the L-shaped (long piece) ends is energized by applying a voltage to the coil 208 of the pachinko launcher 200, the pachinko ball A ball hitting portion 209a for hitting the ball is provided, and a tip portion 209b is provided at the other end (short piece portion) of the L shape. Further, the hitting ball portion 209a and the tip portion 209b are covered with an elastic body (for example, elastic rubber).

  The stator 206 includes a core 207, a yoke 214 above the core 207, and a yoke 215 below the core 207, and magnetic pole portions having arc-shaped magnetic pole surfaces 207 c, 214 c, and 215 c facing the rotor 205, respectively. And arm portions 216 for connecting the yokes 214 and 215 and the core 207 to each other. The width of the core 207 is approximately twice the width of the yoke 214 and the yoke 215. The core 207 is formed in a substantially prismatic shape, and the coil 208 is wound by inserting the core 207 into a bobbin 217 around which the coil 208 is wound. A terminal portion 218 is formed on one flange of the bobbin 217, and terminal pins 219 and 220 for supplying power to the coil 208 are attached to the terminal portion 218. The stator 206 is installed such that the length direction of the core 207 and the yokes 214 and 215 is substantially horizontal.

  The stator 206 is configured by punching steel plates (for example, cold rolled steel plates (SPC), electrogalvanized steel plates (SEC), electromagnetic steel plates such as silicon steel plates), which are soft magnetic materials, into respective predetermined shapes and laminating a predetermined number of sheets. Has been.

  The rotor 205 has a predetermined gap (for example, 0.3 mm) between the magnetic pole surface 214c of the yoke 214 of the stator 206, the magnetic pole surface 215c of the yoke 215, and the magnetic pole surface 207c of the core 207, and the ball bearing 221 The shafts 222 and 223 are pivotally supported. The ball bearings 221 and 222 are press-fitted into the openings 226 and 227 of the bearing holders 224 and 225 made of a nonmagnetic material (for example, aluminum alloy), respectively. Further, the ball bearing 223 is press-fitted into the opening 229 of the plate 228. Further, in the holes 230 and 231 of the yoke 214 of the stator 206 and the holes 232 and 233 of the yoke 215, pins 234, 235, 236, 237, 238, and 239 made of a nonmagnetic material (for example, brass or austenitic stainless steel) are provided. These pins 234, 235, 236, 237, 238, and 239 are respectively attached to the holes and plates of the lid 240 at both ends when the lid 240 and the plate 228 are attached. By being positioned in the hole 228, it is used for positioning to align the axis of the lid 240 and the plate 228. In addition, coil springs 241 and 242 for applying a preload are provided between the ball bearing 221 and the rotor 205 and between the ball bearing 222 and the rotor 205.

A guide 247 is attached to the plate 228 by bolts 243 and 244, and a game ball holding member 245 is attached to the lower end protrusion 246 of the guide 247 by bolts 244. By attaching the game ball holding member 245 to the lower end projection 246, there is no gap between the lower end projection 246 and the rail guide surface 248, and a guide path (rail for launching the game ball toward the rails 25a and 25b (rail). Functioning as an entrance to 25a and 25b). Further, a rib 270 (hereinafter referred to as a protective protrusion 270) is provided below the lower end protrusion 246 (see FIG. 5). Although not shown, rails 25a and 25b are provided on the extended lines of the guide surfaces 248 and 249, respectively.
The lower end protrusion 246 corresponds to the attachment protrusion in the present invention.

  FIG. 7 is an explanatory diagram (sectional view) showing the positional relationship between the game ball holding member 245 and the protective projection 270 when the game ball holding member 245 is attached to the lower end projection 246. In addition, the screw 244 for attaching the game ball holding member 245 to the lower end protrusion 246 is omitted. As shown in the drawing, the height T1 of the protective projection 270 is formed higher than the height T2 of the lower end projection 246, and the height when the game ball holding member 245 is attached to the lower end projection 246. It is formed to be slightly lower than T4 (the height obtained by adding the thicknesses T3 and T2 of the mounting portion 245b of the game ball holding member 245). Further, the protective projection 270 is provided in the vicinity of the tip 245c of the mounting portion 245b of the game ball holding member 245 (closest to the extent that it is substantially in contact or not in contact).

  Thus, by setting [T2 <T1 <T4 (= T2 + T3)], after the game ball holding member 245 is attached to the lower end protrusion 246, the periphery of the game ball holding member 245 can be seen from the S direction in the figure. When gripped, the operator or the like touches the protective projection 270, so that it is almost impossible to touch the tip 245c of the mounting portion 245b. Therefore, by directly gripping the game ball holding member 245 (particularly, the tip 245c of the attachment portion 245b), the attachment portion 245b is deformed from the tip 245c, or dirt is attached to the tip 245c by directly touching the tip 245c. Thus, it is possible to prevent the gaming ball holding member 245 from being deteriorated as much as possible.

  The protective projection 270 may be formed so that the height T1 and the height T4 are equal. That is, by setting [T1 = T4 (= T2 + T3)], the operator or the like may touch the tip 245c of the attachment portion 245b when gripping from the S direction as described above [T1 <T4]. It is even lower than when. Therefore, by directly gripping the game ball holding member 245 (particularly, the tip 245c of the attachment portion 245b), the attachment portion 245b is deformed from the tip 245c, or dirt is attached to the tip 245c by directly touching the tip 245c. Thus, it is possible to prevent the gaming ball holding member 245 from being deteriorated as much as possible.

  A magnet 251 is attached to the end 250 of the guide 247. As the force that acts when the hammer 209 returns from the hitting position (see FIG. 15C or FIG. 16A) to the standby position (see FIG. 15A or FIG. 16C) by the magnet 251, Since the magnetic force by the magnet 251 is added to the force due to the weight of the hammer 209, the speed at which the hammer 209 returns to the standby position can be increased. Further, the end of the shaft 201 passed through the hammer 209 is fixed with a nut 252, whereby the hammer 209 is fixed to the shaft 201. Further, the cover 253 is fixed to the plate 228 by bolts 254, 255, 256, 257. The bolt 255 is provided with a stopper 261 formed by a ring 260 made of elastomer with a screw 258 and an elastic ring 259. That is, the stopper 261 in this embodiment is formed by covering an elastic body with an elastomer. Since the elastomer itself also has elastic force, the stopper 261 can be formed from a material having elastic force, and deterioration of the elastic body itself can be prevented while maintaining the elastic force of the elastic body itself. The lid 240 is attached to the plate 228 with bolts 262 and 263.

  5, 8, and 9 are diagrams illustrating a state in which no voltage is applied to the coil 208 of the pachinko launcher 200. The hammer 209 is supported by the stopper 261. This state is a state in which the hammer 209 and the rotor 205 are in the standby position.

  10-12 is a figure which shows the state which is applying the voltage to the coil 208 of the pachinko launcher 200 and exciting it. At this time, the hammer 209 is restricted by the stopper 261 from the rotational force exceeding the hitting position. This state is a state in which the hammer 209 and the rotor are in the hitting position. When a current is supplied to the coil 208 and the coil 208 is excited, a magnetic field is generated in the stator 206, and N or S poles are generated on the magnetic pole faces 207c, 214c, and 215c. Due to the magnetic field generated from the magnetic pole surfaces 207c, 214c, and 215c, the arm portions 202, 203, and 204 of the rotor 205 are magnetized, and an attractive force acts between the magnetic pole surfaces 215c, 207c, and 214c. Thereby, the arm portions 202, 203, and 204 of the rotor are pulled by the magnetic pole surfaces 215c, 207c, and 214c, respectively, and the end surfaces of the arm portions 202, 203, and 204 of the rotor face the magnetic pole surfaces 215c, 207c, and 214c, respectively. Thus, the finite angle rotor 205 rotates in the clockwise direction in the drawing.

  At that time, the rotor 205 is provided with projecting portions 202c, 203c, and 204c projecting in the rotation direction at the tip ends of the three arm-shaped portions 202, 203, and 204, respectively. As a result, when a voltage is applied to the coil 208 and a magnetic field is generated from the magnetic pole surfaces 215c, 207c, and 214c, magnetization occurs in the protruding portions 202c, 203c, and 204c, respectively, and the magnetization and the magnetic pole surface 215c. , 207c, and 214c generate a force in the rotational direction to rotate the rotor 205. In addition, it is preferable that the protrusions 202c, 203c, and 204c have a length in the protrusion direction of the protrusion that is longer than the width of the protrusion. As a result, magnetization is generated in the direction of the protruding portion. Further, it is preferable that the tips of the protrusions 202c, 203c, and 204c at the standby position of the hammer are closer to the magnetic pole surfaces 215c, 207c, and 214c.

  FIG. 13 is a diagram for explaining the magnetization that occurs in the protruding portion 203c of the arm-shaped portion 203 of the rotor 205 when a voltage is applied to the coil 208 and the coil 208 is excited. When a voltage is applied to the coil 208, the magnetic pole surface 207c side of the core 207 is assumed to be N pole, for example. The rotor 203 is magnetized by the magnetic field (arrow G1) generated by the voltage application of the coil 208. At that time, magnetization (arrow M) is generated in the protruding portion 203c so that the tip portion 203ct side becomes the south pole. That is, magnetization occurs in the protruding portion direction of the protruding portion 203c. Thereby, a force (arrow F) acts on the protrusion 203c in the rotation direction of the rotor 205 due to the interaction with the magnetic field G1. Thereby, rotational torque is generated.

  FIG. 14 is a diagram showing a change in rotational torque acting on the rotor with respect to a rotation angle when a magnetic field is generated when a protrusion is provided at the tip of the arm-shaped portion of the rotor and when no protrusion is provided. FIG. 14A is a diagram for the present embodiment in which a protrusion is provided at the tip of the arm-like portion of the rotor, and FIG. 14B is a diagram in which no protrusion is provided at the tip of the arm-like portion of the rotor. It is a figure with respect to a case. It can be seen that when the protrusion is provided at the tip of the arm-shaped portion of the rotor, the rotational torque is generated from the rotation angle D1 smaller than the rotation angle D2 when the protrusion is not provided. The range indicated by reference signs A1 and A2 in FIG. 14 indicates the operation range of the hammer, the points indicated by reference signs B1 and B2 are the standby positions of the hammer, and the points indicated by reference signs C1 and C2 correspond to the hitting points of the pachinko balls. The torque at point B1 in FIG. 14 (a) is large, the gradient of the torque curve is gentle, and even if the point B1 moves to the left and right, there is little change in the torque value, and therefore there is little effect on flight performance. It can be activated reliably. In the case of FIG. 14 (b), the torque at point B2 is small and the torque rises suddenly. Therefore, if the point B2 fluctuates to the left and right, the flying performance is greatly affected, and in some cases, starting may be difficult. In order to prevent this, it is necessary to move the point B2 to the right, the effective use range is narrow, the variation in flight performance increases, and the efficiency of the aircraft can be reduced.

  10-12, when the voltage applied to the coil 208 is turned off and demagnetized, the balance of weight is lost due to the weight of the hammer 209 and the three arms of the rotor 205, so that the counterclockwise direction is reached. The rotor 205 stops at a stationary position (standby position) where the hammer 209 is supported by the stopper 261 by rotating by a finite angle. Therefore, if the voltage of the coil 208 is repeatedly turned on and off, the pachinko ball (game ball) 500 can be continuously fired with the hammer 209. By making the intensity of this current variable, the rotation speed of the hammer 209 can be made variable and the strength of the hit ball of the pachinko ball can be changed.

  Thus, in the pachinko launching apparatus 200 in the gaming machine according to the present embodiment, the stator 206 has three poles, the rotor 205 has the three arm-shaped portions 202, 203, and 204, and these three arm-shaped portions are Since it is in the angle range of about 180 °, the return speed can be increased due to the influence of the weight balance. In addition, since the rotor 205 has three arm-like portions, the force acting when a voltage is applied to the coil 208 acts on each of the three arm-like portions, so that the rotational torque can be increased. In addition, the rotor 205 is provided with protrusions 202c, 203c, and 204c that protrude in the rotation direction of the rotor 205 when a voltage is applied to the coil 208 to excite it at the tip of each of the three arm-shaped portions. Since the force acting when a voltage is applied to the coil 208 acts on the protrusions 202c, 203c, and 204c of the three arms, the rotational torque can be increased.

  FIG. 15 shows the operation until the hammer 209 at the standby position reaches the hitting position where the pachinko ball 500 is hit, that is, the voltage applied to the coil 208 is turned off, and the voltage is turned on to excite the voltage. It is explanatory drawing shown about operation | movement of the hammer 209 when it does. FIG. 15A shows a state where the hammer 209 is in the standby position, and the hammer 209 is restricted by the magnet 251 and the stopper 261 so that the hammer 209 does not rotate beyond the standby position. At this time, when the voltage applied to the coil 208 is turned on and excited, a force (arrow F, see FIG. 13) toward the hitting position is generated as shown.

  FIG. 15B shows the state of the hammer 209 that is separated from the magnet 251 and the stopper 261 by the force (arrow F) toward the hitting position and the hammer 209 is on the way to the hitting position. FIG. 15C shows a state where the hammer 209 hits the game ball 500 at the hitting position.

  In FIG. 15 (b), the tip 209b of the hammer 209 has a force (tip 209b from the magnet 251) generated by the magnetic force from the magnet 251 in a direction opposite to the force (arrow F) toward the hitting position. The force attracted in the direction of the magnet 251 by the magnetic force, the arrow G2) shown in FIG. However, in the present embodiment, the force (arrow G2) generated by the magnetic force of the magnet 251 is sufficiently smaller than the force (arrow F) toward the hitting ball position (so that “F−G2≈F”). It is said. In other words, it can be said that the force indicated by the arrow F is a sufficiently large force to the extent that the force indicated by the arrow G2 can be ignored.

Thus, the hammer 209 urged by the force (arrow F) toward the hitting position reaches the hitting position shown in FIG. 15C and hits the pachinko ball 500. That is, the pachinko ball 500 is fired, and the pachinko ball rises between the rails 25a and 25b to reach the upper position of the game board 17, and then falls within the game area 26.
When the hammer 209 reaches the hitting position, the stopper 261 restricts the rotational force (the force indicated by the arrow F) so that the hammer 209 does not rotate in the direction beyond the hitting position.

  FIG. 16 shows the operation of the hammer 209 from hitting the pachinko ball 500 to returning to the standby position, that is, the hammer when the voltage applied to the coil 208 is turned on and then deenergized after turning off the voltage. It is explanatory drawing shown about operation | movement of 209. FIG. FIG. 16 (a) shows the state of the hammer 209 immediately after hitting the pachinko ball 500, and the stopper 261 is regulated so as not to rotate further in the rotation direction beyond the hitting position at the hitting position. The hammer 209 generates a force (arrow J1) in the direction toward the standby position (the direction opposite to the hitting ball position, see FIG. 15A) due to the weight of the hammer 209.

  FIG. 16 (b) shows the state of the hammer 209 on the way to the standby position after the hammer 209 is separated from the firing stopper 249 by the force (arrow J1) due to its own weight. FIG. 16C shows a state where the hammer 209 is stationary at the standby position.

In FIG. 16 (b), the tip 209 b of the hammer 209 has a force generated by the magnetic force from the magnet 251 in addition to the force (arrow J 1) due to its own weight (the tip 209 b is directed toward the magnet 251 by the magnetic force from the magnet 251. The force attracted to the arrow G2) will work. That is, the force (arrow G2) generated by this magnetic force is added to the force (arrow J1) due to its own weight, so that the speed at which the tip 209b returns to the standby position can be further increased. Therefore, the speed at which the hammer 209 returns to the standby position is urged by the force (arrow G2) generated by the magnetic force when the hammer 209 is rotated close to the standby position. Accordingly, at this time, a force (arrow J2) obtained by adding a force (arrow G2) generated by the magnetic force of the magnet 251 to the force due to its own weight (arrow J1) is applied to the hammer 209.
Then, when the hammer 209 reaches the standby position, the stopper 261 (and further the magnet 251) applies a rotational force (the force indicated by the arrow J2) so that the hammer 209 does not further rotate in the direction beyond the standby position. Be regulated.

  In addition, according to this embodiment, there can exist the following effects. That is, one stopper 261 restricts the movement of the hammer 209 when the hammer 209 hits the game ball and when returning to the standby position. Thereby, it is possible to reduce the number of parts constituting the pachinko launching device by reducing the number of stoppers that conventionally have to be provided at the standby position and the position when hitting a ball.

  The stopper 261 is provided on the side of the hammer 209 surrounded by the substantially L-shaped short piece and the long piece. In addition, the stopper 261 is disposed at a position where it can contact the short piece portion and the long piece portion. That is, the stopper 261 is arranged inside a rectangle in which at least the short piece portion and the long piece portion of the hammer 209 are vertically and horizontally (or horizontally and vertically), respectively. Therefore, the size of the region formed by the hammer 209 and the stopper 261 is smaller than that in the case where the stopper is provided on the opposite side of the hammer 209 surrounded by the substantially L-shaped short piece and the long piece. can do. Thereby, further miniaturization of the pachinko launching device can be achieved.

  In this embodiment, the case where the rotor has three arms has been described. However, the present invention is not limited to this, and a rotor made of a magnetic material having a plurality of arms and a plurality of arms within an angle range of about 180 °. If so, a rotor having a number of arms other than three arms can be used.

  In the present embodiment, the hammer 209 is fixed to the shaft 201 which is the rotation axis of the rotor 205, but is not limited to this. For example, the hammer 209 and the shaft 201 may be connected by a gear or the like.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented, and the numerical values and the compositions (materials) of the respective components Is just an example. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.
