The person is informed. The special symbol display devices 40 and 41 are each composed of, for example, a plurality of LEDs. When a big win is won, a plurality of specific LEDs are lit, and when it is lost, a specific LED corresponding thereto is displayed. One lights up. The pattern represented by lighting up in this way becomes a special symbol, but this special symbol is displayed in a stopped state after being displayed in a variable manner for a predetermined time. In other words, whenever a special symbol change display is performed, a special symbol stop display is performed, and the lottery result of the jackpot lottery is notified. 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).

  When the launch control board 106 receives the launch control data from the payout control board 103, the launch control board 106 permits the launch. Then, the touch signal from the touch sensor 3b and the input signal from the launch volume 3a are read out, the energization of the launch solenoid 4a is controlled, and the game ball is launched. At this time, the DC voltage is converted by the DC / AC converter 106a provided on the firing control board 106, and the voltage that alternately changes the positive voltage and the negative voltage shown in FIG. 5B is output to the firing solenoid 4a.

As a result, the number of games played in one minute is about 99.9 (pieces / minute) because one shot is fired each time the pulse voltage is applied to the firing solenoid 4a.

  In the present embodiment, the touch sensor signal from the touch sensor 3 b is transmitted from the launch control board 106 to the effect control board 102 via the payout control board 103 and the main control board 101.

  Next, the pachinko launcher 200 for a gaming machine according to the first embodiment of the present invention will be described in detail. FIG. 6 is a schematic diagram of the pachinko launcher 200 at the standby position of the hammer. FIG. 7 is a schematic diagram showing a state after a voltage is applied to the coil, the hammer is rotated, and a game ball is fired.

  As shown in FIG. 6, the pachinko launcher 200 includes a shaft 201 (schematically illustrated) that forms a rotor axis, and a permanent magnet having three arms 202, 203, and 204 within an angle range of approximately 180 °. The rotor 205, the W-shaped three-pole stator 206 that generates a magnetic field that attracts the three arms 202, 203, and 204, the coil 208 wound around the central core 207 of the stator 206, A hammer 209 fixed or coupled to a shaft 201 that is a rotating shaft is provided. The shaft 201, the rotor 205, the stator 206, and the coil 208 constitute a rotary solenoid to form a firing solenoid 4a. The angle formed by each of the three arms is preferably approximately 90 °.

  Of the three arm-shaped portions 202, 203, 204 of the rotor, the ends of the two arm-shaped portions 202, 204 sandwiching the central arm-shaped portion 203 have the same polarity (for example, S pole), and the central arm-shaped portion The end of the portion 203 has a polarity (for example, N pole) different from the polarity of the ends of the two arm-like portions 202 and 204. Such a permanent magnet rotor 205 is heated to, for example, a Curie point or more of a ferromagnetic material such as iron constituting the rotor, and the ends of the two arm portions 202 and 204 have the same polarity (for example, S pole). It is obtained by cooling to room temperature while applying a magnetic force so that the end of the central arm 203 has a polarity (for example, N pole) different from the polarity of the ends of the two arms 202 and 204. It is done. The magnetic force is obtained, for example, by winding a coil around each of the three arm portions 202, 203, and 204 of the rotor and applying a voltage to each coil.

  The shaft 201 is D-cut and is fitted with a D-cut 211 applied to 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 stator 206 includes a core 207, a yoke 214 on the left side of the core 207, and a yoke 215 on the right side of the core 207, and each of the magnetic pole portions having arc-shaped magnetic pole surfaces 207 c, 214 c, 215 c facing the rotor 205. 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 (not shown) is formed on one flange of the bobbin 217, and a terminal pin (not shown) for supplying power to the coil 208 is attached to the terminal portion. The stator 206 is installed such that the length direction of the core 207 and the yokes 214 and 215 is substantially vertical.

  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 a ball bearing (see FIG. (Not shown) so as to be pivotable. In the figure, reference numeral 261 indicates a stopper.

  6 applies a voltage of the first polarity (for example, a negative voltage) shown in FIG. 5 to the coil 208 of the pachinko launcher 200, and the pole face of the yoke closest to each of the ends of the two arm portions is The pole face of the yoke closest to the end of the central arm has a polarity different from that of the ends of the two arms, and the polarity of the end of the central arm is different. Thus, it is a figure which shows the state which is exciting the coil. The arm portions 202, 203, and 204 of the rotor are attracted by the magnetic field generated from the magnetic pole surfaces 215 c, 207 c, and 214 c, and 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.

  7 applies the second polarity (eg, positive voltage) shown in FIG. 5 to the coil 208 of the pachinko launcher 200, and the pole face of the yoke closest to each of the ends of the two arm-shaped portions is the two arms. So that the pole surface of the yoke closest to the end of the central arm has the same polarity as that of the end of the central arm. It is a figure which shows the state which has excited the coil. When a second polarity (for example, a positive voltage) is applied to the coil 208 and current is supplied to excite the coil 208, a reverse magnetic field is generated in the stator 206 when a voltage of the first polarity is applied. Thus, an N pole is generated on the magnetic pole surface 207c, and an S pole is generated on 214c and 215c. A repulsive force acts between the arm portions 202, 203, and 204 of the rotor 205 and the magnetic pole surfaces 215c, 207c, and 214c by the magnetic field generated from the magnetic pole surfaces 207c, 214c, and 215c. As a result, the arm portions 202, 203, and 204 are repelled by the magnetic pole surfaces 215c, 207c, and 214c, respectively, and the end surfaces of the arm portions 202, 203, and 204 are repelled by the magnetic pole surfaces 215c, 207c, and 214c, respectively. In a clockwise direction, the finite angle rotor 205 rotates until the movement of the hammer stops at the stopper 249.

  When the voltage applied to the coil 208 is switched to the voltage of the first polarity, each arm portion of the rotor is pulled by each magnetic pole surface, and the weight of the hammer 209 and the three arms of the rotor 205 are pulled. Since the weight balance is lost due to the shape, the rotor 205 stops at a stationary position (standby position) where the hammer 209 is supported by the stopper 261 by rotating a finite angle counterclockwise. Therefore, if the polarity of the voltage of the coil 208 is repeatedly switched, 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. Further, the return of the hammer is further accelerated by the attractive force due to the magnetic field from the arm-like portions 202, 203, 204 and the magnetic pole surfaces 215c, 207c, 214c by the permanent magnet of the rotor 205. Because of the attractive force, the bounce of the hammer stops less, and it quickly stops at the standby position.

  Next, a pachinko launcher 300 for gaming machines according to a second embodiment of the present invention will be described. In the second embodiment, two arm-shaped portions of the rotor are used. Accordingly, the magnetic pole surface of the yoke of the stator becomes two and can be made more compact. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  FIG. 8 is a schematic diagram of a pachinko launcher 300 for a gaming machine according to the second embodiment. As shown in FIG. 8, the rotor 301 has two arm portions 302 and 303.

  The stator 304 includes a yoke 305 and a yoke 306 on the left side of the yoke 305, each having a magnetic pole part having arc-shaped magnetic pole faces 305c and 306c facing the rotor 301, and a stator arm connecting the magnetic pole parts. Part 307. The yoke 305 and the yoke 306 are formed in a substantially prismatic shape, and the coil is wound by inserting the yoke 305 and the yoke 306 into a bobbin around which the coil 308 is wound. A terminal portion (not shown) is formed on one flange of the bobbin, and a terminal pin (not shown) for supplying power to the coil is attached to the terminal portion. The stator 304 is installed so that the length directions of the yokes 305 and 306 are substantially vertical.

  FIG. 8 shows that the first magnetic pole (for example, negative voltage) shown in FIG. 5 is applied to the coil 308 of the pachinko launcher 300, and the magnetic pole surface of the yoke closest to each of the two magnetic poles has two magnetic poles. It is a figure which shows the state which has excited the coil so that it may have a polarity different from polarity. The magnetic poles 302 and 303 of the rotor are pulled by the magnetic field generated from the magnetic pole surfaces 305 c and 306 c, and 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.

  9 applies the second polarity (for example, positive voltage) shown in FIG. 5 to the coil 308 of the pachinko launcher 300, and the magnetic pole surface of the yoke closest to each of the two magnetic poles has the polarity of the two magnetic poles. It is a figure which shows the state which has excited the coil so that it may have the same polarity. When a second polarity (for example, a positive voltage) is applied to the coil 308 and current is supplied and the coil 308 is excited, a magnetic field opposite to that in the stator 304 when the hammer is in the standby position is generated, and the magnetic pole surface. An N pole is generated at 305c and an S pole is generated at 306c. A repulsive force acts between the magnetic poles 302 and 303 of the rotor 301 and the magnetic pole faces 305c and 306c by the magnetic field generated from the magnetic pole faces 305c and 306c. As a result, the hammer 209 is rotated in the clockwise direction in the figure so that the arm portions 302 and 303 are repelled from the magnetic pole surfaces 305c and 306c, respectively, and the arm portions 302 and 303 are repelled from the magnetic pole surfaces 305c and 306c, respectively. The finite angle rotor 205 rotates until it stops by the stopper 249.

  When the voltage applied to the coil 308 is switched to the voltage of the first polarity, each arm portion of the rotor attracts each magnetic pole surface, and the weight of the hammer 209 and the weight balance of the rotor 205 are lost. Therefore, the rotor 205 stops at a stationary position (standby position) where the hammer 209 is supported by the stopper 261 by rotating a finite angle in the counterclockwise direction. Therefore, if the polarity of the voltage of the coil 308 is repeatedly switched, a pachinko ball (game ball) can be continuously fired by 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 launcher 300 in the gaming machine according to the present embodiment, the stator 304 has two poles, and the rotor 301 has the two arm portions 302 and 303. Therefore, the return speed is increased due to the influence of the weight balance. Can be fast. Further, the return of the hammer is further accelerated by the attractive force due to the magnetic field from the arm portions 202 and 203 and the magnetic pole surfaces 304c and 303c by the permanent magnet of the rotor 205, and when the magnetic force is returned, the attractive force from the magnetic pole surface is also received. Therefore, the bounce of the hammer stopper is reduced, and it quickly stops at the standby position.

  Next, a pachinko launcher 400 for gaming machines according to a third embodiment of the present invention will be described in detail. FIG. 10 is a schematic diagram of a pachinko launching device 400. FIG. 11 is a schematic diagram showing a state after applying a voltage to the coil and rotating the hammer.

  As shown in FIG. 10, the pachinko launcher 400 includes a shaft 201 that forms a rotor axis, a fan-shaped rotor 405 that includes permanent magnets having three magnetic poles 402, 403, and 404 within an angular range of approximately 180 °, and 3 A W-shaped three-pole stator 206 that generates a magnetic field attracting each of the two magnetic poles 402, 403, and 404, a coil 208 wound around a central core 207 of the stator 206, and a shaft 201 that is a rotating shaft of the rotor 405. And a hammer 209 fixed to the head. The shaft 201, the rotor 405, the stator 206, and the coil 208 constitute a rotary solenoid to form a firing solenoid 4a.

Of the three magnetic poles 402, 403, and 404 of the rotor, two magnetic poles 402 and 404 sandwiching the central magnetic pole 403 have the same polarity (for example, S pole), and the central magnetic pole 403 is the same as the two magnetic poles 402 and 404. It has a polarity (for example, N pole) different from the polarity it has. Such a permanent magnet rotor 405 can be obtained, for example, by applying a manufacturing method described in Japanese Patent Application Laid-Open No. 2003-199274 (a rotor, a manufacturing method thereof, and a rotating machine).
Since the third embodiment is the same as the first embodiment except for the rotor, the same constituent elements shown in FIG. 6 are denoted by the same reference numerals and description thereof is omitted.

  The stator 206 is installed such that the length direction of the core 207 and the yokes 214 and 215 is substantially vertical.

  FIG. 10 shows that the first pole (for example, negative voltage) voltage shown in FIG. 5 is applied to the coil 208 of the pachinko launcher 400, and the pole face of the yoke closest to each of the ends of the two arms is two. It is a figure which shows the state which has excited the coil so that the magnetic pole surface of the yoke which has a polarity different from the polarity which a magnetic pole has, and has the polarity different from the polarity which a magnetic pole of a center nearest may have. The magnetic poles 402, 403, and 404 of the rotor are pulled by the magnetic field generated from the magnetic pole faces 215c, 207c, and 214c, and 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.

  11 applies the second polarity (for example, positive voltage) shown in FIG. 5 to the coil 208 of the pachinko launcher 400, and the pole face of the yoke closest to each of the two magnetic poles is the same as the polarity of the two magnetic poles. It is a figure which shows the state which has excited the coil so that the magnetic pole surface of the yoke which has polarity and is closest to the central magnetic pole has the same polarity as that of the central magnetic pole. When a second polarity (for example, a positive voltage) is applied to the coil 208 and current is supplied to excite the coil 208, a reverse magnetic field is generated in the stator 206 when a voltage of the first polarity is applied. Thus, an N pole is generated on the magnetic pole surface 207c, and an S pole is generated on 214c and 215c. A repulsive force acts between the magnetic poles 402, 403, and 404 of the rotor 405 and the magnetic pole faces 215c, 207c, and 214c by the magnetic field generated from the magnetic pole faces 207c, 214c, and 215c. As a result, the rotor magnetic poles 402, 403, and 404 are pulled by the magnetic pole surfaces 215c, 207c, and 214c, respectively, and the rotor magnetic poles 402, 403, and 404 are repelled from the magnetic pole surfaces 215c, 207c, and 214c, respectively. A finite angle rotor 405 rotates in the surrounding direction.

  When the voltage applied to the coil 208 is switched to the voltage of the first polarity, the magnetic poles of the rotor are pulled against the magnetic pole surfaces, and the weight of the hammer 209 and the rotor 205 are fan-shaped. Since the weight balance is lost, the rotor 205 is stationary at a stationary position (standby position) where the hammer 209 is supported by the stopper 261 by rotating a finite angle in the counterclockwise direction. Therefore, if the polarity of the voltage of the coil 208 is repeatedly switched, 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 device 400 in the gaming machine according to the present embodiment, the stator 206 has three poles, the rotor 405 has three magnetic poles 402, 403, and 404, and the rotor 405 has a fan shape. The return speed can be increased under the influence of In addition, since the rotor 405 has three magnetic poles, the force that acts when a voltage is applied to the coil 208 acts on each of the three magnetic poles, so that the rotational torque can also be increased. Further, the return of the hammer is further accelerated by the attractive force due to the magnetic field from the magnetic poles 402, 403, and 404 and the magnetic pole surfaces 215c, 207c, and 214c by the permanent magnet of the rotor 405. As a result, the bounce of the hammer stops less and it quickly stops at the standby position.

  Next, a pachinko launcher 500 for gaming machines according to a fourth embodiment of the present invention will be described. In the fourth embodiment, two rotor magnetic poles are used. Accordingly, the magnetic pole surface of the yoke of the stator becomes two and can be made more compact. In addition, since it is the same as that of 2nd Embodiment except the rotor, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 12 is a schematic diagram of a pachinko launcher 500 for a gaming machine according to the fourth embodiment. As shown in FIG. 12, the rotor 501 has two magnetic poles 502 and 503, and the rotor 501 has a fan shape.

  The stator 304 includes a yoke 305 and a yoke 306 on the left side of the yoke 305, each having a magnetic pole part having arcuate magnetic pole faces 305c and 306c facing the rotor 501, and a stator arm that connects the magnetic pole parts. Part 307. The yoke 305 and the yoke 306 are formed in a substantially prismatic shape, and the coil is wound by inserting the yoke 305 and the core 306 into a bobbin around which the coil 308 is wound. A terminal portion (not shown) is formed on one flange of the bobbin, and a terminal pin (not shown) for supplying power to the coil is attached to the terminal portion.

  12 applies a voltage of the first polarity (for example, negative voltage) shown in FIG. 5 to the coil 308 of the pachinko launcher 500, and the magnetic pole surfaces of the yokes closest to the two magnetic poles have the two magnetic poles. It is a figure which shows the state which has excited the coil so that it may have a polarity different from polarity. The magnetic poles 502 and 503 of the rotor are pulled by the magnetic field generated from the magnetic pole faces 305 c and 306 c, and the hammer 209 is supported by the stopper 261. This state is a state where the hammer 209 and the rotor 501 are in the standby position.

  13 applies the second polarity (for example, positive voltage) shown in FIG. 5 to the coil 308 of the pachinko launcher 400, and the magnetic pole surface of the yoke closest to each of the two magnetic poles has the polarity of the two magnetic poles. It is a figure which shows the state which has excited the coil so that it may have the same polarity. When a second polarity (for example, positive voltage) is applied to the coil 308 and a current is supplied to excite the coil 308, a magnetic field opposite to that when the hammer is in the standby position is generated in the stator 301, and the magnetic pole surface. An N pole is generated at 305c and an S pole is generated at 306c. A repulsive force acts between the magnetic poles 502 and 503 of the rotor 501 and the magnetic pole faces 305c and 306c by the magnetic field generated from the magnetic pole faces 305c and 306c. As a result, the rotor magnetic poles 502 and 503 are repelled by the magnetic pole surfaces 305c and 306c, respectively, and the rotor magnetic poles 502 and 503 are repelled by the magnetic pole surfaces 305c and 306c, respectively. 501 rotates.

  When the voltage applied to the coil 308 is switched to the voltage of the first polarity, the respective arms of the rotor are pulled by the respective magnetic pole surfaces, and the weight of the hammer 209 and the rotor 205 are fan-shaped so that the weight balance is achieved. Therefore, the rotor 205 is stationary at a stationary position (standby position) where the hammer 209 is supported by the stopper 261. Therefore, if the polarity of the voltage of the coil 308 is repeatedly switched, a pachinko ball (game ball) can be continuously fired by 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 device 500 in the gaming machine according to the present embodiment, the stator 304 has two poles, the rotor 501 has two magnetic poles 502 and 503, and the rotor 501 has a fan shape. Thus, the return speed can be increased. Further, the return of the hammer is further accelerated by the attractive force due to the magnetic field from the magnetic poles 502 and 503 and the magnetic pole surfaces 305c and 306c by the permanent magnet of the rotor 505, and when returning, the attractive force from the magnetic pole surface is also received by the magnetic force. For this reason, the bounce of the hammer stopper is reduced, and it quickly stops at the standby position.

  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.
