  By the way, in the pachinko gaming machine 10 of the present embodiment, when a game ball enters the above-mentioned center start winning opening 14, start gate 18, and side start winning opening 40A, the following three types of lotteries are performed, and the player can enjoy it. I can do it.

  Specifically, as the first type of lottery, every time a game ball enters the central start winning opening 14, a determination is made as to whether or not to execute the “first jackpot game”. The result is displayed on the liquid crystal display screen 34. On the liquid crystal display screen 34, usually three left, middle and right special symbols 13A, 13B and 13C are displayed side by side. Each of these special symbols 13A, 13B, and 13C is composed of, for example, a plurality of types that express numbers from “0” to “11”. Usually, each special symbol 13A, 13B, and 13C has a predetermined value. Kinds of things are stopped. Then, when a game ball enters the central start winning opening 14 and the winning / failing determination is made, these three special symbols 13A, 13B, and 13C are scrolled up and down, and after a predetermined time, for example, left The special symbols 13A, 13B, 13C are stopped and displayed in the order of right, middle. At this time, if the result of the game success / failure determination is “big hit”, for example, all of the special symbols 13A, 13B, and 13C are the same symbol, that is, a rough eye.

  When the left and right special symbols 13A and 13C are stopped and displayed with the same symbol and only the middle special symbol 13B is variably displayed, a predetermined reach effect image (for example, a character image) is displayed on the liquid crystal display screen 34. The When the game button 27C provided at the lower left corner of the front frame 10Z is pressed, images (for example, character images) other than the special symbols 13A, 13B, and 13C that are variably displayed on the liquid crystal display screen 34 are arbitrarily selected by the player. It can be stopped at the timing.

  When the special symbols 13A, 13B, and 13C enter the central start winning opening 14 during the variable display or “hit state” on the liquid crystal display screen 34, up to four winning balls are stored as holding balls, The number of stored memories (the number of held balls) is displayed using the upper half LEDs of the above-described number-of-holds display section 36. When the special symbols 13A, 13B, and 13C are stopped or displayed, or the “hit state” is ended, the number of reserved memories is reduced by one, and the special symbols 13A, 13B, and 13C are again displayed after being variably displayed. The game success / failure determination result is displayed. Here, the probability of winning the jackpot is set to 1/399, for example. If the result of the game success / failure determination is “big hit”, the central movable door 15T of the central big prize opening 15 is opened for a predetermined period.

  As described above, when a game ball enters the central start winning opening 14, whether or not to open the central large winning opening 15 is determined instead of simply opening the central large winning opening 15. In addition, since the central movable door 15T is opened and the central special prize opening 15 is opened for a predetermined period, the player can be entertained by determining whether or not it is successful. Then, an interest can be given to whether or not a game ball enters the central start winning opening 14, and after a game ball enters the central start winning opening 14, You can be interested in whether or not to enter the ball.

  As the second type of lottery, every time a game ball passes through the inside of the start gate 18, a preliminary determination as to whether or not the advance / retreat guide member 230 is to be operated is performed. It is displayed on the part 36F. Specifically, when the game ball passes through the inside of the start gate 18, after the numerical symbols composed of the numbers “0” to “9” are variably displayed over the predetermined period on the normal symbol display portion 36 </ b> F, A predetermined numerical symbol is stopped and displayed. At this time, when the stop-displayed number is an odd number, it is “win”, and when it is an even number, it is “out”. Here, the probability of winning is set to 99/100, for example.

  Then, when the result of the preliminary success / failure determination is successful, the revolving door 220 opens and the advance / retreat guide member 230 moves forward for a predetermined period (for example, 0.088 seconds), and the game ball is placed in the side start winning opening 40A. You can enter the ball.

  When the game symbol passes through the inside of the start gate 18 while the numeric symbol is variably displayed or “winning state” in the normal symbol display unit 36F, up to four winning balls are stored as reserved balls, The number of reserved memories (the number of reserved balls) is displayed using the lower half LEDs of the above-described number-of-holds display section 36. When the numerical symbol is stopped or the “hit state” is finished, the number of reserved memories is reduced by one, and after the numerical symbol is variably displayed, it is stopped and displayed, and the preliminary determination result is displayed.

  As described above, the side start winning opening 40A is normally closed, and the game ball can enter due to the game ball passing through the inside of the start gate 18. It is possible to be interested in whether or not the game ball passes, and after the game ball passes through the inside of the start gate 18, it is interested in whether or not the game ball enters the side start winning opening 40A. Can be made. Moreover, when the game ball passes through the inside of the start gate 18, whether or not to open the side start winning opening 40A is determined instead of simply opening the side start winning opening 40A. Since the moving door 220 is opened and the advancing / retreating guide member 230 is projected to open the side start winning opening 40A for a predetermined period, the player can be entertained by determining whether or not he / she is successful.

  As a third type of lottery, every time a game ball enters the side start winning opening 40A, it is determined whether or not to execute the “second jackpot game”, and the result of the determination is displayed on the liquid crystal display screen. 34. The display method of determination on the liquid crystal display screen 34 is the same as the display method of the determination result of “first jackpot game” as described above, such as decoration colors and patterns for the special symbols 13A, 13B, and 13C, and the liquid crystal The background images and the like of the special symbols 13A, 13B, and 13C on the display screen 34 are different from the case of the determination result of “first jackpot game”. Here, the probability of winning a jackpot is set to 1/399, and the probability of hitting a jackpot is set to 398/399. That is, when a game ball enters the side start winning opening 40A, a big hit or a small hit is won. If the determination result of the game is “big hit”, the central movable door 15T of the central big prize opening 15 is opened for a predetermined period. When the special symbols 13A, 13B, and 13C enter the side start winning opening 40A while the special symbols 13A, 13B, and 13C are variably displayed on the liquid crystal display screen 34, the winning balls are not held.

  Here, when the game determination result is a small hit, the side domain movable door 37T at the side big prize opening 37A is opened, and the regulating piece 38K is retracted to the inside about one second after the side domain door 37T is opened. The continuous winning opening 37Z is opened for 0.388 seconds. Here, when the period between the opening and closing of the Sai domain movable door 37T is referred to as a “round”, one round ends when the opening time of the Sai Domain movable door 37T reaches 1.6 seconds. . When a game ball enters the continuous winning opening 37Z, the next round is continuously executed after the round ends. Further, the “small hit state” (the opening operation of the rhino domain movable door 37T) is continued up to, for example, 16 rounds. After the “small hit state” is completed, the “short time state” is set with a probability of 25/50 (41/50 in the short time). If the game ball that entered the side big prize opening 37A does not enter the continuous prize opening 37Z, it will end in the first round, and if it enters the continuous prize opening 37Z, the side will start from the next round. Without opening / closing the main movable door 37T, it becomes a “hit state”, and the central movable door 15T of the central big prize opening 15 is opened / closed for a predetermined period, and the remaining rounds (for example, 15 rounds) are executed.

  Thus, the side domain movable door 37T of the side big prize opening 37A is normally closed, so that the game ball can enter due to the game ball entering the side start prize opening 40A. It is possible to make the player interested in whether or not a game ball enters the side start winning opening 40A. Moreover, when a game ball enters the side start winning opening 40A, it is determined whether to open the side domain movable door 37T of the side large winning opening 37A or the central movable door 15T of the central large winning opening 15, The side movable door 37T is opened for a predetermined period in the case of a small hit, and the central movable door 15T is opened for a predetermined period in the case of a big hit, so that the player can be entertained by the determination. In other words, after a game ball has entered the side start winning opening 40A, it can be interested whether or not the game ball enters the central grand prize opening 15 or the side large winning opening 37A.

  Furthermore, since the central movable door 15T of the central grand prize opening 15 is opened for a predetermined period due to the game ball having entered the side special prize opening 37A, the game ball enters the side special prize opening 37A. It is possible to be interested in whether or not to play, and after a game ball has entered the side big prize opening 37A, it is interested in whether or not the game ball that has entered enters the continuous prize opening 37Z. be able to.

  As described above, the central grand prize opening 15 is configured to be opened and closed by the central movable door 15T, and a game ball enters the central start prize opening 14 provided on the upper side of the central big prize opening 15 to determine whether or not When the determination is a win and when the game ball enters the side start winning opening 40A and the determination is a big win (second win), the central movable door 15T of the central big win 15 is predetermined. Open over time. Here, when the period from when the central movable door 15T is opened until it is closed is referred to as “round”, for example, in one round, the opening time of the central movable door 15T has reached a predetermined time (30 seconds), or The process ends when any one of the predetermined number (10) of the game balls has entered the central prize winning opening 15 is satisfied first. Further, the “big hit state” (the opening operation of the central movable door 15T) is continued up to, for example, 15 rounds. Then, after the “big hit state” is completed, the “short time state” is set with a probability of 25/50 (41/50 during the short time).

  In the “short-time state”, the number of seconds for opening the revolving door 220 and the number of seconds for advancement of the advance / retreat guide member 230 are increased from, for example, 0.088 seconds in the normal state to 1.7 seconds. There will be 3 more games. By maintaining the advantageous state of “short time state”, it becomes easier to enter the side start winning opening 40A during the “short time state”, so that it becomes easier to obtain a winning ball than in the normal gaming state, It will be in a state to suppress the decrease of And it can play a game until the next jackpot, suppressing reducing a ball.

  Next, the configuration of the right side winning unit 100 will be described with reference to FIGS. The right side winning unit 100 includes a mounting base board 110 laid on the front surface of the game board 11, a right side guiding member 24R and a general winning port 20 provided on the front side of the mounting base board 110, and the rear side of the mounting base board 110.

U-shaped or square U-shaped recesses opened forward are formed in the bottom wall of the upper housing part 215A and the bottom wall of the lower housing part 215B, and these recessed parts penetrate the rear part of the detection switch 280. The game ball passage hole 281 (see FIGS. 8 and 9) communicates.

  A gate-shaped protrusion 216 penetrating in the front-rear direction from the middle position in the front-rear direction on the upper surface of the second housing component 215 is erected, and the fixing pieces 217, 217 are laterally extended from both legs of the gate-shaped protrusion 216. Is overhanging. The first housing component 211 and the second housing component 215 are combined and fixed by superimposing these fixing pieces 217 and 217 on the rear end surfaces of the pair of screw fixing columns 212 and 212 and fixing the screws.

  A solenoid 270 is placed on the upper surface of the second housing component 215 on the rear side of the gate-shaped protrusion 216. The solenoid 270 includes an exciting coil 270C inside the metal frame 270F, and is fixed to the rear surface of the gate-shaped protrusion 216 via a bracket 272 screwed to the outside of the metal frame 270F (see FIG. 9). .

  That is, a pair of fixing pieces 273 and 273 projecting laterally are provided at the front end of the bracket 272. These fixing pieces 273 and 273 are overlapped on the rear surfaces of the fixing pieces 217 and 217 formed on the gate-shaped protrusion 216, and screws that unite and fix the first housing component 211 and the second housing component 215 are used. It passes through the fixing pieces 273 and 273. In other words, the first housing component 211, the second housing component 215, and the solenoid 270 include the gate-shaped protrusion 216 of the second housing component 215, the rear end of the first housing component 211, and the front end of the bracket 272. It is fixed with a common screw in a state of being sandwiched between the front and rear. A plunger 274 (see FIG. 7, which corresponds to the “linear motion member” of the present invention) that linearly moves in the front-rear direction with a predetermined stroke is inserted in the center of the exciting coil 270 </ b> C of the solenoid 270. Among them, a flange portion 274F (see FIG. 8) projecting sideways is formed at the tip portion protruding from the exciting coil 270C.

  The plunger 274 is attached with a connection assisting member 275 for connecting the plunger 274 and one end of a seesaw member 250 described below. The connection assisting member 275 has a structure in which a pair of arc walls 275B and 275B protrude from the ring portion 275A loosely fitted to the outside of the plunger 274 toward the flange portion 274F (see FIG. 15). A metal compression coil spring 276 wound around the outside of the plunger 274 is provided in a stretched state between the ring portion 275A of the connection auxiliary member 275 and the front end surface of the solenoid 270, and the arc of the connection auxiliary member 275 is provided. The walls 275B and 275B are pressed against the flange portion 274F of the plunger 274 by the compression coil spring 276. A portion surrounded by the ring portion 275A, the pair of arcuate walls 275B and 275B, and the flange portion 274F of the plunger 274 has rectangular depressions 277 and 277 (FIG. 15 shows only one depression 277. Here, the upper end portion of the seesaw member 250 is connected thereto.

  The solenoid 270 attracts the plunger 274 against the compression coil spring 276 by excitation of the excitation coil 270C (state shown in FIG. 15B). When the excitation is stopped, the plunger 274 protrudes from the solenoid 270 by the urging force of the compression coil spring 276 (state shown in FIG. 15A).

  The seesaw member 250 is rotatable about a rotation axis that is parallel and horizontal to the game board 11. As shown in FIGS. 7 and 8, the seesaw member 250 has a gate-like structure in which the upper ends of a pair of connecting arms 251 and 251 opposed in the horizontal direction are connected by a connecting wall 252. A pair of rotating shafts 253 and 253 project in opposite directions from the outer surface near the upper end of the pair of connecting arms 251 and 251. The rotation shaft portions 253 and 253 have a cylindrical shape and are rotatably supported by the resin housing 210.

  Specifically, as shown in FIG. 9, U-shaped grooves 218 and 218 that open to the front are formed on both legs of the gate-shaped protrusion 216 in the second housing component 215, and the U-shaped grooves 218 and 218 are formed in the U-shaped grooves 218 and 218. The rotating shaft portions 253 and 253 are received. In this state, the rear end surface of the first housing component 211 is disposed in front of the rotation shaft portions 253 and 253 to prohibit the removal of the rotation shaft portions 253 and 253 from the U-shaped grooves 218 and 218. .

  In the seesaw member 250, a pair of upper end connection convex portions 254 and 254 are provided at positions on the upper end side of the rotation shaft portions 253 and 253. The pair of upper end connection convex portions 254 and 254 protrude from the inner surfaces facing each other of the pair of connection arms 251 and 251 so as to approach each other and have a cylindrical shape. The tip ends of the upper end connecting convex portions 254 and 254 are engaged with concave and convex recesses 277 and 277 provided in the plunger 274. As a result, the seesaw member 250 can rotate about the rotation shaft portions 253 and 253 in conjunction with the linear movement of the plunger 274 in the front-rear direction (see FIG. 15).

  As shown in FIG. 12, the connecting wall 252 of the seesaw member 250 is provided on the front side of the upper end connecting convex portions 254 and 254 and the rotating shaft portions 253 and 253. A rear surface 254M on the upper end connecting projections 254, 254 side of the connecting wall 252 faces the tip end surface of the plunger 274, and at the center of the lower side of the connecting wall 252 is the tip of the plunger 274 when the seesaw member 250 is rotated. In order to avoid interference with the portion (flange portion 274F), a rectangular cutout portion 256 (see FIGS. 9 to 11) is formed. Further, a triangular protrusion 257 that slightly protrudes toward the plunger 274 side (rear side) is provided on the lower side of the rear surface 254M of the communication wall 252.

  In the seesaw member 250, the connecting wall 252 arranged in front of the rotating shafts 253 and 253 serves as a weight, and the upper end of the seesaw member 250 rotates toward the front of the gaming machine (counterclockwise in FIG. 12). It is biased to rotate in the rotation direction).

  Of the pair of connection arms 251 and 251 in the seesaw member 250, a pair of lower end connection projections 255 is arranged at the lower end opposite to the upper end connection projections 254 and 254 with the rotation shaft portions 253 and 253 interposed therebetween. , 255 (see FIG. 8). The pair of lower end connecting convex portions 255 and 255 protrudes laterally from the outer surfaces of the pair of connecting arms 251 and 251 and is parallel to the rotating shaft portions 253 and 253.

  Stopper recesses 258 and 258 are formed in the lower end connecting projections 255 and 255. The stopper recesses 258 and 258 are, for example, formed in a recessed shape on the outer peripheral surface of the cylindrical body constituting the lower end connecting convex portion 255, and have a groove-shaped structure with an L-shaped cross section extending along the axial direction of the cylindrical body. . The stopper recesses 258 and 258 will be described in detail later.

  The seesaw member 250 and an advancing / retreating guide member 230, which will be described later, are connected by the lower end connecting projections 255 and 255.

  Similar to the seesaw member 250, the pivot door 220 is pivotable about a pivot axis that is parallel and horizontal to the game board 11. The revolving door 220 is connected between a pair of side walls 221 and 221 opposed in the horizontal direction by a shutter wall 222 that opens and closes the side start winning opening 40A. A pair of rotating shaft portions 223 and 223 protrude from the outer surfaces of the pair of side walls 221 and 221 in opposite directions. The rotation shaft portions 223 and 223 are unevenly distributed at positions away from the shutter wall 222 and are rotatably supported on both side walls of the resin housing 210. Specifically, as shown in FIG. 7, U-shaped grooves 214 and 214 that are opened rearward are formed on both side walls of the first housing component 211, and the rotation shaft portions 223 and 214 are formed in the U-shaped grooves 214 and 214. 223 is accepted. In this state, the openings of the U-shaped grooves 214 and 214 are closed at the front end surface of the second housing component 215 to prohibit the rotation shaft portions 223 and 223 from being detached from the U-shaped grooves 214 and 214. .

  The shutter wall 222 has a cross section orthogonal to the rotation shaft portions 223 and 223 curved in a substantially “<” shape. The front end portion of the shutter wall 222 that protrudes forward has a V-shaped cross section to prevent the game ball from being caught. Cam protrusions 224 and 224 are respectively provided on the opposite side of the pair of side walls 221 and 221 with respect to the shutter wall 222 with the rotation shafts 223 and 223 interposed therebetween. The cam protrusions 224 and 224 can come into contact with the advance / retreat guide member 230 described below. In conjunction with the forward / backward movement of the advance / retreat guide member 230 in the front-rear direction, the rotary door 220 opens the side start winning opening 40A. It opens and closes.

  The advance / retreat guide member 230 is accommodated in the resin housing 210 at a position directly below the solenoid 270, the seesaw member 250, and the rotary door 220 described above.

  As shown in FIGS. 13 and 14, the advance / retreat guide member 230 has a flat structure in which the lateral width direction is short with respect to the front-rear direction and is thin in the vertical direction, and is substantially open to the front when viewed from above. A “U” -shaped slide base 231 and a guide plate 240 that communicates with the front ends of both sides 232 and 232 of the slide base 231 and extends forward. An opening 238 that is long in the front-rear direction is formed between both sides 232 and 232 of the slide base 231. The opening 238 communicates with the game ball passage hole 281 of the detection switch 280 in the vertical direction regardless of the position where the advance / retreat guide member 230 is located between the protruding position and the retracted position. The passage of the sphere is allowed (see FIG. 9).

  The lateral width of the guide plate 240 is slightly narrower than the lateral width of the lower side of the side start winning opening 40A, and the lateral width of the slide base 231 is wider than the lateral width of the lower side of the side starting winning opening 40A. Thereby, only the guide plate 240 of the advance / retreat guide member 230 can protrude forward of the game board 11. Then, both sides 232 and 232 of the slide base 231 projecting laterally from the guide plate 240 are inserted into slide receiving portions 219 (see FIGS. 9 and 10) extending in the front-rear direction on both side walls of the resin housing 210. It is possible to slide.

  The upper surface of the guide plate 240 is inclined so that both side portions in the lateral width direction are lowered toward the side, and is inclined extremely gently so that the space between both sides is lowered toward the center portion (FIG. 13 ( B)). In addition, the upper surface of the guide plate 240 is relatively gently lowered from the front end portion toward the rear, and is relatively steeply lowered in the middle (see FIG. 14B). Furthermore, a protrusion 241 (corresponding to the “projection” of the present invention) extends in the front-rear direction at the center in the width direction on the upper surface of the guide plate 240. By providing the protrusions 241, the game ball received by the guide plate 240 not only wins the side start winning opening 40 </ b> A by the inclination of the upper surface but also falls from the guide plate 240 without winning. In addition, the player can be interested in the whereabouts of the game ball received by the advance / retreat guide member 230.

  Furthermore, in a normal gaming state where it is not desired to win the side start winning opening 40A as much as possible, since the protrusion time is short, when the game ball collides with the ridge 241, the game ball changes the rolling direction in the lateral direction of the ridge 241. In other words, the guide plate 240 is retracted in the gap, and the winning of the game ball can be limited as much as possible. The rear end edge of the guide plate 240 (the front end edge of the opening 238) has an arcuate shape that protrudes forward.

  Side walls 233 and 233 are formed in the advance / retreat guide member 230 between both sides in the width direction of the guide plate 240 and both sides 232 and 232 of the slide base 231. The side wall parts 233 and 233 are gradually increased toward the rear. The upper end surface of the side wall portion 233 is in order of a gradual first inclined surface 233A, a first horizontal surface 233B, a steep second inclined surface 233C, and a second horizontal surface 233D in order from the front side. It is flush with the upper end surface of the slide base 231. Further, the cam projection 224 of the rotary door 220 can come into contact with the second inclined surface 233C.

  As shown in FIG. 14 (A), connecting recesses 234 and 234 are formed in the inner side surfaces of the slide base 231 opposite to each other on the inner side surfaces 232 and 232, respectively. Each of the connecting recesses 234 and 234 is a composite recess having a relatively deep second recess 236 inside the relatively shallow first recess 235.

  As shown in FIG. 14B, a pair of facing surfaces 235A and 235A facing in the front-rear direction in the first recess 235 are inclined so as to approach each other from the upper surface to the lower surface of the advance / retreat guide member 230. Yes. On the other hand, the second recessed portion 236 is formed by further depression of the central portion of the first recessed portion 235, and among the pair of sliding contact surfaces 236A and 236B opposed in the front-rear direction, the front sliding contact surface 236A located on the front side. However, it is a vertical plane orthogonal to the linear movement direction of the advance / retreat guide member 230. Further, the rear sliding contact surface 236B facing the front sliding contact surface 236A approaches the front sliding contact surface 236A side in the vertical direction in the vertical direction perpendicular to the linear movement direction of the advance / retreat guide member 230. The stopper contact surface 237S which has the protruding step portion 237 (corresponding to the “sheet stopper protrusion” of the present invention) and is inclined so that the upper surface of the step portion 237 is lowered toward the front sliding contact surface 236A. It has become. The stepped portion 237 will be described in detail later together with the stopper recesses 258 and 258 of the seesaw member 250 described above.

  In the second recesses 236 and 236, lower end connecting projections 255 and 255 provided at the lower end of the seesaw member 250 are inserted (see FIG. 15), and the first recesses 235 and 235 are connected to the seesaw member 250, respectively. The lower end portions of the arms 251 and 251 are received. Here, the inclination of the pair of opposing surfaces 235A and 235A in the first recess 235 is determined by the retreat position where the advance / retreat guide member 230 protrudes forward from the side start winning port 40A and the back of the side start winning port 40A. It is configured not to interfere with the connecting arms 251 and 251 within the swing range of the connecting arms 251 and 251 when moving linearly between the positions.

  The winning mechanism unit 200 having the above configuration operates as follows. That is, since the solenoid 270 is not normally excited, the plunger 274 protrudes forward (the state of FIG. 15A). When the solenoid 270 is excited from this state and the plunger 274 is attracted backward, the seesaw member 250 rotates about the rotation shafts 253 and 253. That is, the lower end portion of the seesaw member 250 is rotated from the rear position to the front of the gaming machine from the rotation shaft portions 253 and 253, and the lower end connecting convex portions 255 and 255 are the front sliding surfaces of the second concave portions 236 and 236. Slidably contact 236A and 236A and push forward. As a result, the advance / retreat guide member 230 is pushed forward of the gaming machine, and the guide plate 240 protrudes from the side start winning opening 40A to the front side of the game board 11 (state shown in FIG. 15B). In the process in which the advance / retreat guide member 230 moves forward, the cam projections 224 and 224 of the rotary door 220 are in sliding contact with the second inclined surfaces 233C and 233C of the side wall portions 233 and 233, and the rotary door 220 is the rotary shaft portion. Rotate to the rear side of the gaming machine around 223,223. Thereby, the side start winning opening 40A is changed from the closed state to the open state. Further, while the advance / retreat guide member 230 is located at the projecting position, the cam projections 224, 224 remain in contact with the side wall portions 233, 233 of the advance / retreat guide member 230, so the side start winning opening 40A is opened. Maintained in a state.

  Then, when the game ball falls on the upper surface of the guide plate 240 and moves backward, it enters the side start winning opening 40A, falls from the guide plate 240 inside the side start winning opening 40A, and the advance / retreat guide member 230 It is detected by a detection switch 280 provided below.

  Here, the rotating door 220 does not rotate until the cam protrusions 224 and 224 come into contact with the second inclined surfaces 233C and 233C, and holds the side start winning opening 40A in a closed state. Specifically, when the guide plate 240 of the advance / retreat guide member 230 protrudes about a half from the side start winning opening 40A, the rotating door 220 starts to rotate with a delay, and the guide plate 240 protrudes about a half. During a relatively short period of time until it completely protrudes, the side start winning opening 40A changes from the fully closed state to the fully open state.

  When excitation of the solenoid 270 is stopped in a state where the advance / retreat guide member 230 protrudes forward from the side start winning opening 40A (state of FIG. 15B), the plunger 274 protrudes forward by the compression coil spring 276. Then, the lower end portion of the seesaw member 250 is rotated backward about the gaming machine around the rotation shaft portions 253 and 253, and the lower end portion of the seesaw member 250 is moved from the front position to the rear position from the rotation shaft portions 253 and 253. Moving. At this time, the lower end connecting convex portions 255 and 255 are slidably brought into contact with the rear sliding surfaces 236B and 236B of the second concave portions 236 and 236 and pushed backward. Thereby, the advancing / retreating guide member 230 is pulled back to the gaming machine, and the guide plate 240 is retracted to the back side of the side start winning prize opening 40A. Also, immediately after the advance / retreat guide member 230 starts moving toward the retracted position, the rotating door 220 rotates due to its own weight, and the cam protrusion 224 comes into sliding contact with the second inclined surface 233C to reach the retracted position. Before reaching the second inclined surface 233C.

  Thereby, the revolving door 220 starts the closing operation immediately after the advance / retreat guide member 230 starts the retreating operation, and when the guide plate 240 retreats about half, the revolving door 220 completely opens the side start winning opening 40A. Close to. That is, the side start winning opening 40A is quickly closed before the guide plate 240 is completely retracted to the back of the side start winning opening 40A to prohibit the entry of the game ball. With such a configuration, the pivot door 220 is not opened until the protruding amount of the guide plate 240 becomes large to some extent. In particular, in the normal gaming state in which it is desired to limit the winning as much as possible, the protruding of the guide plate 240. Since the time is short, and in addition to this, the opening time of the rotating door 220 is short, so that the winning of the game ball can be more restricted.

  The description regarding the configuration of the pachinko gaming machine 10 according to the present embodiment has been described above. Next, the effect of the pachinko gaming machine 10 of this embodiment will be described. When a plurality of game balls are sequentially driven into the game area R1 by operating the operation knob 28, some of the game balls flow down from the upper area of the display frame 23 to the left side area in the game area R1. . Then, these game balls are guided by the wind guide 19 and the sub guide surface 24W of the left side guide member 24L and flow down to the lower region, and a part of another game ball is a left side region of the display frame 23. Then, it passes through the warp rod 39, rolls on the stage 23S, and flows down to the lower region of the display frame 23. During this time, some of the game balls are awarded to the central start winning opening 14 and the general winning openings 20 and 21, and the winning balls are paid out to the upper plate 27A. In addition, when winning at the central start winning opening 14, a lottery (whether or not is determined) whether or not to open the central movable door 15T is performed. If the lottery result is a win, the central movable door 15T is opened and the display frame body 23 is opened. Many of the game balls flowing down the lower area of the can enter the central grand prize opening 15.

  In addition, a part of the game balls that are driven into the game area R1 pass through a narrow area between the upper right portion of the display frame 23 and the guide rail 12 one by one, and a side area of the display frame 23 To the upper end of Then, the game balls flow down one by one through the side area of the display frame 23 through the gateway R2. Then, at the upper end portion of the right side region of the display frame body 23, the game ball is first divided into whether or not it passes through the inside of the start gate 18. Here, when the game ball passes through the inside of the start gate 18, a lottery is performed as to whether or not the side start prize opening 40A can be won. If the lottery result is a win, a predetermined period (for example, a normal game) In the state, it is possible to win the side start winning opening 40A once for 0.088 seconds and three times for 1.7 seconds in the short-time gaming state. When winning the side start winning opening 40A, a lottery is performed to determine whether to open the rhinodomain movable door 37T or the central movable door 15T. Then, when the central movable door 37T is opened and the central movable door 15T is opened after the continuous winning opening 37Z is opened or the central movable door 15T is directly opened by lottery, a large amount of game balls are entered into the central large winning opening 15. The ball can be entered and many prize balls can be obtained. In addition, it is determined whether to enter the normal gaming state or the short-time gaming state after the jackpot state ends based on the winning at the side start winning opening 40A, and the gaming state determined after the jackpot state ends due to the continuous winning hole 37Z In the case of a configuration that shifts to (normal gaming state or short-time gaming state), even if the winning timing is measured so that the continuous winning opening 37Z is not won when the normal gaming state is determined, By providing the rhino domain movable door 37T at a position where the distance from launching to winning is long, the winning timing for the continuous winning opening 37Z is difficult to measure.

  When the side special winning opening 37A is open, the side guide nail group 11S serves as a guide for entering the game ball into the side special winning opening 37A. Further, most of the game balls that have not entered the side large winning opening 37A and the side start winning opening 40A are received by the sub guide surface 24V of the right side guide member 24R, and the main guide nail group 11U is received from the sub guide surface 24V. Is guided to the main guiding surface 11V, and is further guided to the central special prize opening 15 by the main guiding surface 11V. At this time, if the central movable door 15T is open, the game ball guided to the sub guide surface 24V of the right side guide member 24R and the main guide surface 11V of the main guide nail group 11U has a high probability of receiving the central prize opening 15. To win a prize.

  By the way, in this gaming machine, the advance / retreat guide member 230 retracted in the back of the side start winning opening 40A is pulled out to the front surface of the game board 11 with, for example, a wire inserted from the gap of the gaming machine, There is a possibility that an illegal act of playing a game in a state and entering a game ball into the side start winning opening 40A to acquire a prize ball may be performed.

  In order to prevent such an illegal act, stopper recesses 258 and 258 are formed in the lower end connecting projections 255 and 255 of the seesaw member 250, and the rear sliding contact surfaces of the second recesses 236 and 236 in the advance / retreat guide member 230 are formed. Step portions 237 and 237 are formed on 236B.

  Specifically, as shown in FIG. 15, the step portions 237 and 237 are formed at the lower end portions of the seesaw member 250 when the excitation of the solenoid 270 is stopped in the rear sliding surface 236 </ b> B in the second recesses 236 and 236. Is formed in a portion that comes into contact with the lower end connecting projections 255 and 255 of the seesaw member 250 when the game machine is turned rearward. As described above, the step portion 237 is provided with the stopper contact surface 237S that is inclined so as to descend toward the front sliding contact surface 236A.

  On the other hand, as shown in FIG. 15, in the stopper recesses 258 and 258, the excitation of the solenoid 270 stops in the lower end connection projections 255 and 255, and the lower end of the seesaw member 250 rotates toward the rear of the gaming machine. In this case, the second recesses 236 and 236 are formed in portions that are in contact with the rear sliding contact surface 236B.

  As shown in FIG. 12, the stopper recess 258 includes two planes M1 and M2 that intersect each other. That is, they are the first plane M1 facing in the opposite direction to the rotation shaft portions 253 and 253, and the second plane M2 facing the back of the gaming machine. When the excitation of the solenoid 270 is stopped and the lower end portion of the seesaw member 250 rotates toward the rear of the gaming machine, first, as shown in the change from FIG. 16 (A) to FIG. The first edge portion E1 where the plane M1 intersects the outer peripheral surface of the lower end connecting convex portion 255 contacts the stopper contact surface 237S of the step portion 237 (see FIG. 16A). As the seesaw member 250 rotates, the lower end connecting projection 255 comes into sliding contact with the rear sliding contact surface 236 </ b> B, and the lower end connecting projection 255 is positioned behind the rotating shafts 253 and 253 of the seesaw member 250. Further, when the second edge portion E2 where the second plane M2 and the outer peripheral surface of the lower end connecting convex portion 255 intersect is in contact with the lower portion of the rear sliding contact surface 236B from the step portion 237, the stopper concave portion The first plane M1 of 258 is in surface contact with the stopper contact surface 237S of the step portion 237 (see FIG. 16C).

  When the advance / retreat guide member 230 is illegally pulled forward, as shown in the change from FIG. 16 (D) to FIG. 16 (C), the lower end connecting convex portion 255 of the seesaw member 250 has the rear sliding contact surface 236B. The advance / retreat guide member 230 moves to a position where the first flat surface M1 of the stopper recess 258 contacts the stopper contact surface 237S. However, even if the advance / retreat guide member 230 is further pulled forward from this position, the sliding contact between the lower end connecting projection 255 and the rear sliding contact surface 236B is prohibited, and the first edge E1 of the stopper recess 258 is a stepped portion. Can't get over 237. At this time, the seesaw member 250 is stretched between the rotation shaft portions 253 and 253 and the advance / retreat guide member 230 (stepped portion 237). As a result, it becomes impossible to pull the advance / retreat guide member 230 forward so that the guide plate 240 protrudes in front of the side start winning opening 40A, thereby preventing an illegal prize ball from being obtained.

  Here, when the advance / retreat guide member 230 is pulled forward, the pulling force becomes an upward force F1 perpendicular to the stopper contact surface 237S of the step portion 237, and the seesaw member 250 is slightly inclined upward. The triangular protrusion 257 formed on the connecting wall 252 of the seesaw member 250 is engaged with the flange portion 274F of the plunger 274. Thereby, since the rotation of the seesaw member 250 is more strongly prohibited, the illegal act of pulling the advance / retreat guide member 230 toward the front and projecting the guide plate 240 to the front of the side start winning opening 40A is more reliably prevented. be able to.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, when the advance / retreat guide member 230 is pulled in front of the side start winning opening 40A, the advance / retreat guide member 230 may protrude in front of the side start winning opening 40A. Therefore, the advancing / retreating guide member 230 is pulled out from the side start winning prize port 40A, and the illegality of entering the game ball by the advancing / retreating guide member 230 in this state can be prevented.

  Further, since the side start winning opening 40A is not opened unless the advance / retreat guide member 230 is projected forward of the side start winning opening 40A, it is possible to reliably prevent illegal entry of game balls into the side start winning opening 40A. Further, since the drive source for moving the advance / retreat guide member 230 and the drive source for rotating the rotary door 220 can be used together by the common solenoid 270, the cost can be reduced.

  Although not belonging to the scope of the present invention, in this embodiment, when the advance / retreat guide member 230 is pulled forward, the lower end portion (lower end connection convex portion 255) of the seesaw member 250 and the advance / retreat guide member 230 are disposed behind. Instead of prohibiting the sliding contact with the side sliding contact surface 236B, by prohibiting the sliding contact between the upper end connecting convex portion 254 of the seesaw member 250 and the depression recess 277, the front surface of the game board 11 of the advance / retreat guide member 230 is prevented. Even if it is configured to prohibit protrusion from the same, the same effects as in the present embodiment can be obtained.

A pair of door drive protrusion walls 433 and 433 are formed to protrude. The entire rear portion of the base portion 431 from the door drive protrusion wall 433 is a power receiving portion 430P that is thick in the vertical direction so as to have an upper surface that is flush with the upper surface of the rear end portion of the door drive protrusion wall 433. ing.

  A pair of connecting recesses 434 and 434 are formed in a recessed manner on the opposite inner side surfaces of the power receiving portion 430P facing each other with the ball passage long hole 438 interposed therebetween. Each connection recess 434 includes a substantially triangular interference avoidance recess 435 whose bottom end is narrowed, and an engagement recess 435 that is recessed and formed in the back surface of the interference avoidance recess 435 away from the ball passage long hole 438 and extends vertically. And a groove portion 436. The front sliding contact surface 436A disposed on the front side of the engagement groove 436 extends straight in the vertical direction. The rear sliding contact surface 436B disposed on the rear side of the engagement groove 436 projects downward from the intermediate position in the vertical direction to form the seesaw stopper 437 according to the present invention. A stopper contact surface 437S at the upper end of the seesaw stopper portion 437 is slightly inclined so as to descend toward the front sliding contact surface 436A (see FIG. 21).

  As shown in FIGS. 18 and 21, each door drive protrusion 433 includes an intermediate depression 433K at an intermediate position in the front-rear direction, and the front side of the intermediate depression 433K is the front pressing protrusion 441 according to the present invention. A rear side pressing protrusion 442 according to the present invention is a rear side from the intermediate depression 433K. The rear side pressing protrusion 442 has the same height as the power receiving part 430P, and the front side pressing protrusion 441 is lower than the power receiving part 430P. Further, the bottom surface of the intermediate depressed portion 433K is a horizontal and flat intermediate depressed flat surface 433N. And the rear surface of the front side press protrusion 441 is the obstruction | occlusion press part 441K which concerns on this invention, and has stood | started up perpendicularly | vertically from the middle depression flat surface 433N. Further, the upper surface of the front pressing projection 441 is a door stopper 441J according to the present invention, and is horizontally flat. On the other hand, the front surface of the rear pressing protrusion 242 is an open pressing portion 442Z according to the present invention, and this also rises vertically from the intermediate depressed flat surface 433N. In addition, the front surface of the front pressing protrusion 441 is parallel to the closing pressing portion 441K, which is the rear surface, and gently inclines forward from the middle, and extends to the rear ends of the outer downward inclined surfaces 440S and 440S described above. .

  The connecting recesses 434 and 434 in the movable tongue 430 are engaged with the lower end of the seesaw member 250, and the side walls 433 and 433 of the movable tongue 430 are engaged with the door rotation protrusions 424 and 424 of the rotation door 420. Are engaged. Thereby, the movable tongue 430 is driven by receiving power from the solenoid 270 via the seesaw member 250, and the rotating door 420 is driven by receiving power from the movable tongue 430 (see FIG. 22). In addition, about transmission of the motive power from the seesaw member 250 to the movable tongue 430, since it is the same as that of 1st Embodiment, description is abbreviate | omitted.

  Next, transmission of power from the movable tongue 430 to the rotating door 420 will be described. The door drive protrusions 433 and 433 of the movable tongue 430 are engaged with the door rotation protrusions 424 and 424 of the rotation door 420, respectively, so that the rotation door 420 receives power from the movable tongue 430. Receiving and turning. Specifically, the movable tongue side 430 is disposed at the rear end retracted position (which also corresponds to the “retracted position” of the present invention), and the entire protruding and projecting side part 440 is retracted to the back side of the side start winning opening 40A. In this state, the door rotation protrusion 424 is disposed above the door stopper 441J in the front pressing protrusion 441 (state shown in FIG. 22). At this time, the rotation shaft portion 423 of the rotation door 420 is located obliquely forward from the door rotation protrusion 424. At this time, a first space S1 according to the present invention is formed between the lower end portion of the door rotation protrusion 424 and the open pressing portion 442Z of the rear pressing protrusion 442.

  Then, when the movable tongue 430 moves forward from the rear end retracted position, the front pressing protrusion 441 moves forward, as shown in the change to FIGS. 22 to 24, and the lower end of the door rotation protrusion 424. The front stopper 441 of the front pressing projection 441 does not face the door stopper 441J in the vertical direction, and the lower end of the door rotation projection 424 faces the intermediate depression flat surface 433N in the vertical direction and the intermediate depression flat surface 433N. In the meantime, the rotation space of the door rotation protrusion 424 is secured.

  When the movable tongue 430 moves further forward, the lower end of the door rotation protrusion 424 moves in the first space S1, and during this time, the movable tongue 430 moves forward but the rotation door. 420 is maintained in a stopped state. Then, as shown in FIG. 23, when the protruding / projecting protrusion 440 of the movable tongue 430 protrudes from the side start winning opening 40A by a predetermined amount, the lower end of the door turning protrusion 424 is the rear pressing protrusion 442. It contacts the front surface 442Z. Further, when the movable tongue 430 further advances, the door main wall 422A of the rotary door 420 is lifted, the side start winning opening 40A is opened (see FIGS. 23 and 24), and the movable tongue 430 is moved. When the front end operating position (corresponding to the “protruding position” of the present invention) is reached, the turning door 420 is fully opened, and a game ball can be won in the side start winning opening 40A. More specifically, when the rotating door 420 is pushed by the rear pressing protrusion 442 and rotates by a certain angle, the rotating door 420 is rotated toward the open end position by its own weight. In other words, the pivot door 420 starts the pivoting operation when the protrusion / projection protrusion 440 protrudes about half from the side start winning opening 40A, and the protrusion / protrusion protrusion 440 protrudes approximately half after it protrudes completely. During a relatively short period of time, the side start winning opening 40A changes from the fully closed state to the fully open state. As described above, in this embodiment, the front door open prize is achieved by a two-step operation in which the movable door 430 starts moving forward and the turning door 420 stops halfway and the turning door 420 starts to open halfway. The mouth 40A is opened. Then, when a game ball falls on the upper surface of the protruding and protruding protrusion 440 protruding from the side start winning opening 40A, the game ball is guided by the protruding and protruding protrusion 440 to win the side start winning opening 40A and win a prize. The game ball is detected by a detection switch (not shown).

  In the state in which the pivot door 420 is completely opened, as shown in FIG. 24, the positioning contact portion 425 of the side wall 421 contacts the upper surface of the rear pressing projection 442, and the pivot door 420 is opened. Positioned at the end position. Thereby, shakiness of the rotation door 420 is controlled. In this state, a second space S <b> 2 according to the present invention is formed between the lower end portion of the door rotation protrusion 424 and the opening pressing portion 442 </ b> Z of the rear pressing protrusion 442.

  Further, when the movable tongue 430 is retracted from the front end operating position, the front pressing protrusion 241 moves rearward as shown in the changes to FIGS. At this time, the lower end portion of the door rotation protrusion 424 moves relatively in the second space S2 toward the front pressing protrusion 441. As a result, a part of the protruding and protruding protrusion 440 in the movable tongue 430 moves into the front opening winning opening 40A (from the state in which the door rotation protrusion 424 is in contact with the opening pressing portion 442Z, the closing pressing portion 441K is contacted). The revolving door 420 is maintained in an open state during the movement in the second space S2 until it comes into contact. The movable tongue 430 receives a front open prize by a predetermined amount (a distance that moves in the second space S2 from the state in which the door rotation protrusion 424 is in contact with the opening pressing portion 442Z until it is in contact with the closing pressing portion 441K). When moved into the opening 40 </ b> A, the closing pressing portion 441 </ b> K of the front pressing protrusion 441 comes into contact with the lower end portion of the door rotation protrusion 424. At this time, the protruding and protruding protrusion 440 of the movable tongue 430 is accommodated in the side start winning prize opening 40A by about half. When the movable tongue 430 is further retracted, the movable door 430 is moved so as to be closed as the movable tongue 430 is retracted. The side start winning opening 40A is completely closed and stopped, and the movable tongue 430 is further retracted behind the side start winning opening 40A so that the lower end of the door turning protrusion 424 is connected to the door stopper 441J. Return to the initial state of facing up and down. As described above, in the present embodiment, the front opening prize is obtained by a two-step operation in which the movable door 430 starts moving backward and stops until the middle, and the pivot door 420 starts to close halfway. The mouth 40A is closed.

  By the way, in the state where the side start winning opening 40A is closed (the state shown in FIG. 22), for example, when the turning door 420 is to be pry open with a wire or the like, the door turning protrusion 424 is turned to the opening side. Then, it comes into contact with the door stopper 441J of the front pressing protrusion 441 in the vertical direction. As a result, unauthorized opening of the pivot door 420 is prohibited. Here, the direction in which the door turning protrusion 424 pushes the door stopper 441J of the front pressing protrusion 441 is in the vertical direction, and is orthogonal to the movable direction (front-rear direction) of the movable tongue 430. Therefore, when an improper external force is applied to the pivot door 420, the door stopper 441J of the movable tongue 430 is surely prevented from being illegally opened without being moved in the movable direction. Can do.

  Next, the effect of this embodiment is demonstrated. Similarly to the first embodiment, when the lottery result indicating whether or not winning is possible at the side start winning opening 40A is a win, the movable tongue 430 moves forward in front of the side start winning opening 40A and the game ball To the side start winning opening 40A, and the turning door 420 for opening the side start winning opening 40A is opened. Here, in the present embodiment, the opening of the side start winning opening 40A is performed in a two-step operation in which the movable tongue 430 moves forward and the turning door 420 starts to open in the middle of the advancement. You can be interested in the movement. Moreover, according to the configuration of the present embodiment, it is possible to prevent winning of the game ball until the movable tongue 430 can receive the game ball. Further, when a game ball is received on the side of the protrusion / projection protrusion 440, the game ball is repelled outward and does not enter the side start winning opening 40A, but a game is played in the middle of the protrusion / protrusion protrusion 440. When the ball is received, the game balls are gathered at the center in the width direction of the intruding protrusion side 440 and guided to the back side of the side start winning opening 40A. The player can be interested in whether the ball is accepted.

  When a predetermined period of time elapses after the movable tongue 430 protrudes, the movable tongue 430 is retracted and accommodated to some extent in the side start winning opening 40A, and then the turning door 420 is closed to the side start winning opening 40A. Entry is restricted. Thus, in this embodiment, since the closing of the side start winning opening 40A is performed by a new operation that has not been conventionally performed, it is possible to give the player a fresh taste and enhance the taste. Here, if the door main wall 422A of the pivot door 420 moves vertically downward from the open end position and closes, the game ball received by the protruding and projecting side 440 during the retraction of the movable tongue 430 is the door main. There is a possibility that the wall 422A will repel the outside. However, in the present embodiment, the door main wall 422A rotates around the rotation shaft portion 423 so as to scrape the game ball into the back side of the side start winning opening 40A, so that it is easy to win the game ball. Can please the player.

  By the way, in the present embodiment, similarly to the first embodiment, the seesaw stopper 437 restricts the rotation of the seesaw member 250 even if the movable tongue 430 is illegally pulled out. It is possible to prevent an illegal act of playing a game in the state of being pulled out and entering a game ball into the side start winning opening 40A to acquire a prize ball.

  Further, in a state where the side start winning opening 40A is closed (see FIG. 22), the turning door 420 is illegally opened, and a game is played in that state to enter a game ball into the side start winning opening 40A. In this embodiment, as described above, when the side start winning opening 40A is closed, the door rotation protrusion 424 rotates the door stopper portion 441J. This kind of fraud is prevented. Moreover, since the door rotation protrusions 424 are arranged on both sides of the rotation door 420 and the door stoppers 441J are arranged on both sides of the movable tongue 430, the door rotation protrusions 424, the door Compared with the case where only one set of stopper portions 441J is provided, the load is distributed and deformation is prevented.

  As described above, in this embodiment, even if the movable tongue 430 is illegally pulled out, the seesaw stopper portion 437 restricts the rotation of the seesaw member 250, so that the movable tongue 430 is connected to the side start winning opening 40A. It is possible to prevent fraud that pulls forward. Moreover, even if the side door winning opening 40A is closed and attempts to open the revolving door 420 illegally, the door stopper 441J restricts the opening operation of the revolving door 420, so that the revolving door 420 is illegally opened. Can be prevented.
