Description

  The present invention relates to a pachinko gaming machine, and more particularly, to a pachinko gaming machine that takes measures against the act of forcibly opening an opening / closing member of a winning device.

  The pachinko gaming machine includes an opening / closing member that is driven by a driving source such as a solenoid, and is provided with a winning device that controls the winning of a game ball to the winning opening by opening / closing the winning opening. The opening / closing member is in a closed state in which the winning opening is closed in the initial state, and is opened when the predetermined condition is satisfied during the game. A game ball won in the opened winning opening is detected by a game ball detector disposed inside the winning device. Based on this, the pachinko gaming machine acquires a random number used for the big hit lottery and a predetermined number of prize balls.

  However, for such a winning device, an illegal act of inserting a wire or the like from the gap of the pachinko gaming machine and hooking it on the opening / closing member to forcibly open the opening / closing member to win a game ball in the winning opening is made. ing. Conventionally, a winning device described in Patent Document 1 is known as a winning device that copes with such an illegal act.

  The winning device described in Patent Literature 1 includes an opening / closing member, a solenoid that drives the opening / closing member, and a connecting member (oscillating crank) that connects the solenoid and the opening / closing member. The front end of the plunger (plunger head) abuts on the swinging crank and restricts the swinging crank movement, thereby preventing the opening / closing member from being forcibly released.

JP 2008-48900 A

  However, in the winning device configured as described above, when the solenoid is not activated and the opening / closing member is in the closed state, the opening / closing member cannot be forcibly opened even if the opening / closing member is pulled with a wire or the like. If the opening and closing member is hooked with a wire etc. aiming at the time when the opening and closing member is opened, the opening and closing member can not return to the closed state, so it can be forcibly opened Met.

  Therefore, in view of the above circumstances, the present invention prevents a game ball that has won a prize opening from being detected unless the driving source is in operation even when the opening and closing member is forcibly opened, thereby forcibly opening the opening and closing member. The purpose is to suppress the act of illegally winning a game ball.

The pachinko gaming machine according to the present invention is a winning device having a winning opening, an opening / closing member that opens and closes the winning opening, and a drive source that drives the opening / closing member. It is operated for a time and includes a winning device that opens and closes the opening and closing member to change the ease of winning the game ball into the winning port. The winning device is a game ball (hereinafter referred to as “winning ball”) that has won the winning port. ) And a ball passage portion for bringing the winning ball to the gaming ball detector, and based on the fact that the winning ball is detected by the gaming ball detector In a pachinko gaming machine in which a big hit lottery and / or a predetermined number of prize balls are made, the prize-winning device is driven by the drive source and can restrict the prize balls to the game ball detector. With The regulating member is in a state in which the game ball is restricted from passing through the ball passage portion regardless of whether the opening / closing member is open or not when the driving source is inactive, and the driving source is activated. that the, Ri Do a state where a game ball is allowed to pass through the ball passage, the driving source is provided with a forward retractable linear member, the linear motion member, along said linear motion member A sliding member is slidable, and the opening / closing member closes the winning opening when the sliding member is in the front position, and opens the winning opening when the sliding member is in the rear position. The regulating member is coupled to the sliding member, and the regulating member regulates the passing of the game ball through the ball passage portion when the linear motion member is in the forward movement position, and the linear motion member is in the backward movement position. When connected to the linear motion member to allow the game ball to pass through the ball passage portion The linear motion member is in the forward position regardless of the position of the sliding member when the drive source is not operated, and the linear motion member is retracted and the sliding member is retracted when the drive source is operated. It moves to the rear position .

  According to the pachinko gaming machine of the present invention, when the drive source is operated while satisfying a predetermined condition and the opening / closing member is opened based on this, the restricting member is in a state where the passage restriction of the ball passage portion is released. Therefore, the game ball won in the winning opening passes through the ball passage portion and is detected by the game ball detector. On the other hand, when the opening / closing member is forcibly opened using a wire or the like even though the predetermined condition is not satisfied, the drive member is not activated, so the restricting member restricts the passage of the ball passage portion. Is in a state of being. Therefore, even if a game ball is won at the winning opening, the winning ball is blocked on the ball passage portion before reaching the game ball detector and is not detected by the game ball detector, so the game ball is counted as a winning ball. There will be no jackpot lottery or prize ball. Accordingly, even if the game ball is illegally won by forcibly opening the opening / closing member, there is no profit for the fraudulent person. Therefore, the act of forcibly opening the opening / closing member and illegally winning the game ball can be suppressed.

The upper part 143 of the shutter piece 142 is notched in a circular arc shape downward so as to match the lower end shape of the tip end part 114 b of the plunger 114. 6A, when the solenoid 112 is not operated, the shutter piece 142 is moved from the upper portion 143 where the rotation shaft portion 144 is formed by the front end portion 109 of the horizontal protrusion 108 described later. It is supported in a posture that gradually protrudes forward toward the lower portion 145 on the opposite side (a posture in which the inclination angle of the rear surface 142a of the shutter piece 142 with respect to the virtual vertical surface is about 45 degrees). In this state, the front surface 145a of the lower portion 145 of the shutter piece 142 is in a state substantially along the vertical direction, and faces the winning ball passing hole 50 of the attachment board portion 48 from the rear side to restrict the passage of the game ball. Yes. As a result, the game ball won in the second starting port 51b by forcibly opening the opening / closing members 76 and 83 is prevented from rolling from the second ball passage portion 69 to the third ball passage portion 99. .

  Here, as shown in FIG. 6A, the holder member 102 has a middle plate portion 107 that is substantially L-shaped when viewed from the right side and that forms the solenoid holder 105. The middle plate portion 107 is composed of a horizontal protrusion portion 108 and a vertical portion 110, and a lower surface 108 a on the rear side of the horizontal protrusion portion 108 and a front surface 110 a of the vertical portion 110 have rolled the third ball passage portion 99. Is a guide surface that guides the detection hole 55 toward the detection hole 55 of the second start port SW54b. The horizontal protrusion 108 has a length dimension in the front-rear direction equal to that of the solenoid 112 in the front-rear direction. On the rear side of the upper surface 108b of the horizontal protrusion 108, the solenoid body 113 is placed and fixed. The front side of the upper surface 108b of the horizontal protrusion 108 is an engagement surface on which the shutter piece 142 supported by the plunger cover 135 rides when the solenoid 112 is operated and the plunger 114 moves rearward. Yes. Further, the front end surface 108c of the horizontal protrusion 108 is an inclined surface that is inclined forward from the top to the bottom so that the shutter piece 142 can easily ride when the solenoid 112 is operated. Thus, when the solenoid 112 is activated, the shutter piece 142 slides the rear surface 142a along the front end surface 108c of the horizontal protruding portion 108 and rides on the front side of the upper surface 108b of the horizontal protruding portion 108 in the left-right direction. The game ball that pivots upward about the pivot shaft 144 along the path, cancels the passage restriction of the winning ball passage hole 50, and wins the second starting port 51b is passed from the second ball passage portion 69 to the third ball. It can be rolled to the passage portion 99 (see FIG. 6B).

(3) Description of game state etc. Next, the game state etc. of the pachinko gaming machine 1 of the embodiment will be described. The pachinko gaming machine 1 according to the embodiment has four game states, a normal game state, a short-time game state, a probability variation game state, and a latent probability game state, and a jackpot game and a jackpot game.

  The short-time gaming state refers to a state in which a game ball is more likely to win the second starting port 51b than in the normal gaming state. In the normal gaming state, the winning probability of the normal symbol lottery is about 1/10, and the normal symbol variation time is 4 Second, the opening time of the opening and closing members 76 and 83 is 0.15 seconds, and the opening and closing members 76 and 83 are opened once, whereas in the short-time gaming state, the winning probability of the normal symbol lottery is about 9/10. The symbol variation time is 1.5 seconds, the opening time of the opening and closing members 76 and 83 is 1.80 seconds, and the opening times of the opening and closing members 76 and 83 are three.

  The probable gaming state is a state where it is easier to win a big hit than the normal gaming state, and a game ball is easy to win the second starting port 51b. In the normal gaming state, the probability of winning a big hit is about 1/300. On the other hand, in the probability variation gaming state, the jackpot winning probability is about 1/30. Also, in the probability variation gaming state, the winning probability of the normal symbol lottery is about 9/10, the normal symbol variation time is 1.5 seconds, the opening time of the opening and closing members 76 and 83 is 1.80 seconds, and the opening and closing members 76 and 83 are the same as in the short-time gaming state. Has been opened three times.

  The latent game state means a state where it is easier to win a jackpot than the normal game state. In the latent game state, the jackpot winning probability is about 1/30 as in the case of the probability variation game state. In the latent game state, as in the normal game state, the winning probability of the normal symbol lottery is about 1/10, the normal symbol fluctuation time is 4 seconds, the opening time of the opening and closing members 76 and 83 is 0.15 seconds, and the opening and closing members 76, 83 is opened once.

  In the initial state (that is, when the first game is started when the power is turned on), if a big win occurs, the big win game 71 is opened and closed a predetermined number of times, Transition to the gaming state according to the type of jackpot. There are 2R (round) latent big hits as short hits where almost no prize balls can be expected, and 15R (round) probable big hits, 15R (round). ) There is usually a jackpot. In addition to these jackpots, there is a jackpot. In addition, a round means the open period of the big winning opening 71. In the 2R latent winning jackpot, after performing a jackpot game that opens the winning prize opening 71 twice in a very short time, transitions to the latent winning gaming state, and in the 15R probability changing jackpot, the jackpot gaming that opens the winning prize opening 71 15 times. After having performed, it changes to a probability change game state, and in 15R normal jackpot, after performing the jackpot game which opens the big winning opening 71 15 times, it changes to a time-short game state. The small hit is an operation that apparently does not differ from the 2R latent big hit, and a small hit game that opens the big winning opening 71 twice in a very short time is performed, but the gaming state does not change. It should be noted that the transition to the normal gaming state is also made when the special symbol change is performed 100 times without causing a big hit in the middle of the short-time gaming state.

  Note that the lottery for the jackpot and the jackpot is performed using a jackpot random number, and when the jackpot is won, the lottery for which type of jackpot will be the jackpot is performed using the jackpot symbol random number. As shown in FIGS. 9 (a) and 9 (b), the jackpot random number takes a value in the range of 0 to 299. In the normal gaming state or the short-time gaming state, the ratio of winning the jackpot is 1 / A random number value to be won for the jackpot is determined to be 300, and a random value to be won for the jackpot is determined so that the ratio of winning the jackpot is 3/300. In the jackpot random number, a random number value for winning the jackpot is determined so that the winning ratio for winning the jackpot is 10/300 in the probability variation gaming state or the latent probability gaming state, and the ratio for winning the jackpot is 3 A random number value to be won on a small hit is determined so as to be / 300. As shown in FIGS. 9 (c) and 9 (d), the jackpot symbol random number takes a value in the range of 0 to 249. For winning to the first start opening 51 a, 15 R is usually won by big hit The random number value to be won for each jackpot is determined so that the winning ratio for the 15R probability variation jackpot is 75/250, and the winning ratio for the 2R latent chance jackpot is 75/250, and the second start For winning to the mouth 51b, the winning ratio for 15R normal jackpot is 100/250, the winning ratio for 15R probability variation jackpot is 125/250, and the winning ratio for 2R latent jackpot is 25/250. A random number value to be won for each jackpot is determined as described above, and the percentage to win per long is higher than when winning the first starting port 51a.

(4) Operation of Pachinko Game Machine Next, the operation of the main control board 20 will be described based on FIGS. Each counter, which will be described later, is provided in the RAM and cleared to zero when the pachinko gaming machine 1 is powered on.

  [Main-side timer interrupt process] The main control board 20 repeats the main-side timer interrupt process shown in FIG. 10 every short time, for example, 4 msec. First, the main control board 20 updates the random number update process for updating the jackpot random number used for the jackpot lottery, the symbol random number for determining the type of jackpot symbol, the variation pattern random number for determining the variation pattern, the winning random number used for the normal symbol lottery, etc. Is performed (step S101).

  Next, the main control board 20 performs a large winning opening SW process (S104) and a normal winning opening SW process (S105) in addition to a start opening SW process (S102) and a gate SW process (S103) which will be described later. In the big winning opening SW processing, if the big winning opening SW 74 is ON, it is determined whether or not the big hit game or the small hit game is in progress (a hit game flag described later is ON). If it is medium, 1 is added to the value C of the winning prize counter and 1 is added to the value of the big winning counter. The normal winning opening SW process is a process of adding 1 to the value of the normal winning opening counter if the normal winning opening SW 91 is ON.

  Subsequently, the main control board 20 performs a special symbol process (S106), a normal symbol process (S107), a big prize opening process (S108), and an electric chew process (S109), which will be described later. Then, the main control board 20 sets a command for paying out the number of prize balls according to the value of the big prize mouth counter and the number of prize balls according to the value of the normal prize mouth counter, A prize ball process (S110) for clearing the counter to zero is performed, and an output process (S111) for outputting the command set in each of the above processes to the payout control board 21 and the effect control board 22 is performed.

  [Starting Port SW Process] As shown in FIG. 11, in the starting port SW process, the main control board 20 determines whether or not the first starting port SW54a is turned on (S201). If the process proceeds and is ON, it is determined whether or not the value U1 of the first start port hold counter that counts the number of jackpot random numbers stored in the first hold storage unit 27a is less than the upper limit of 4 (S202). . If it is not less than 4, the process proceeds to step S206. If it is less than 4, 1 is added to U1 (S203), a jackpot random number is acquired and stored in the first reserved storage unit 27a, and a jackpot symbol random number, etc. Is acquired and stored in a predetermined storage area (S204), and a first pending number increase command is set (S205).

  In step S206, the main control board 20 determines whether or not the second start port SW54b is turned on. If not, the main control board 20 finishes the start port SW process. If it is turned on, the main control board 20 stores it in the second hold storage unit 27b. It is determined whether or not the value U2 of the second start port hold counter that counts the number of jackpot random numbers that are being used is less than the upper limit of 4 (S207). If it is not less than 4, the start-up SW processing is terminated. If it is less than 4, 1 is added to U2 (S208), a big hit random number is obtained and stored in the second reserved storage unit 27b, and the big hit symbol is obtained. A random number or the like is acquired and stored in a predetermined storage area (S209), a second hold number increase command is set (S210), and the start port SW process is terminated.

  [Gate SW Processing] As shown in FIG. 12, in the gate SW processing, the main control board 20 determines whether or not the gate SW 81 is turned on (S301). If so, it is determined whether the value G of the gate hold counter is less than the upper limit of 4 (S302). If it is not less than 4, the gate SW processing is terminated. If it is less than 4, 1 is added to G (S303), a random number used for normal symbol lottery is acquired and stored in a predetermined storage area (S304), The gate SW process ends.

  [Special Symbol Processing] As shown in FIG. 13, in the special symbol processing, the main control board 20 makes a winning game flag indicating whether or not a winning game is being played (that is, a small winning game flag, a long winning game flag, or a short game flag). It is determined whether or not the winning game flag) is ON (S401). If it is ON, the special symbol processing is finished, and if it is not ON, it is determined whether or not the special symbol is changing (S402). If it is changing, the process proceeds to step S411. If it is not changing, it is determined whether or not the value U2 of the second start port hold counter or the value U1 of the first start port hold counter is 1 or more (S403, S405). ). If U2 or U1 is not 1 or more, the special symbol processing is finished. If U2 or U1 is 1 or more, 1 is subtracted from U2 or U1 (S404, S406) and stored in step S204 or S209. The jackpot determination processing is performed using the hit jackpot random number (S407).

  In the jackpot determination process (S407), as shown in FIG. 14, the main control board 20 determines whether the jackpot random number stored in step S204 or S209 is a jackpot using the jackpot determination table (S501), If it is a jackpot, determine which jackpot symbol the jackpot symbol represents, and set the jackpot symbol (YES in S502, S503, S504), if it is a jackpot, set the jackpot symbol (S502) If NO, S505, YES, S506), and if it is neither big hit nor small hit, set a lost symbol (NO, S507 in S505). Note that the type of jackpot is determined by the jackpot symbol (see FIGS. 9C and 9D).

  Subsequently, the main control board 20 performs a variation pattern selection process as shown in FIG. 13 (S408). In the variation pattern selection process, if it is determined that the jackpot is determined in the immediately preceding jackpot determination process, the jackpot table is referred to as a variation pattern table indicating the correspondence between the random value and the variation pattern, and if it is determined that the jackpot is small, Refer to the winning table, and if it is determined that it is neither big hit nor small hit, refer to the lost table and determine which variation pattern the variation pattern random number stored in step S204 or S209 indicates. To set the variation pattern. Note that the variation pattern includes information indicating the variation time.

  Thereafter, the main control board 20 starts the variation of the special symbol in the first special symbol display 14a or the second special symbol display 14b (S409), sets a variation start command (S410), and proceeds to step S411. . In step S411, it is determined whether or not the variation time of the special symbol has elapsed. If it has not elapsed, the special symbol processing is terminated, but if it has elapsed, the variation of the special symbol is stopped and set in the jackpot determination processing. The special symbol is fixedly displayed with the symbol that has been displayed (S412), and a variable stop command is set (S413). Then, as processing during stoppage (S414), processing related to ON / OFF of various game flags (time-short game flag, probability change game flag, latent probability game flag, small hit game flag, long hit game flag, short hit game flag) is performed. If it is a big win or a small win, the opening is started and the opening command is set to finish the special symbol processing.

  [Normal Symbol Processing] As shown in FIG. 15, in the normal symbol processing, the main control board 20 determines whether or not an auxiliary game flag indicating whether or not an auxiliary game is in progress (S601). If the normal symbol processing is finished, and if it is not ON, it is determined whether or not the normal symbol is changing (S602). If it is changing, the process proceeds to step S609. If it is not changing, it is determined whether or not the value G of the gate hold counter is 1 or more (S603). If G is not 1 or more, normal symbol processing is performed. When G is 1 or more, 1 is subtracted from G (S604), it is determined whether or not the winning random number stored in step S304 is hit (S605), and a stop symbol is selected (S606). ). Then, a variation time corresponding to the gaming state (in this embodiment, 4 seconds for the normal gaming state or the latent probability gaming state, 1.5 seconds for the short-time gaming state or the probability variation gaming state) is selected (S607). The change of the symbol is started (S608), and the process proceeds to step S609.

  In step S609, the main control board 20 determines whether or not the variation time has elapsed, and if not, the normal symbol processing ends, but if it has elapsed, the variation of the ordinary symbol is stopped and stopped. Is displayed (S610). If the stop symbol is a symbol indicating winning (YES in S611), the auxiliary game flag is turned ON (S612). If the symbol indicating a loss is determined (NO in S611), the normal symbol processing is terminated.

  [Big prize opening process] As shown in FIG. 16, in the big prize opening process, the main control board 20 first determines whether or not the winning game flag is ON (S701). If it is ON, it is determined whether or not opening is in progress (S702). The opening is a period from the start of the jackpot game to the start of the first round. If it is determined that the opening is in progress, the main control board 20 determines whether or not the opening time has elapsed (S703). A maximum R number (round number) and an operation pattern according to the type are set (S704). Then, the value C of the winning number counter is cleared to zero (S705), 1 is added to the value R of the round counter (S706), and the operation (opening) of the big winning opening 71 is started (S707).

  Next, the main control board 20 determines whether or not the operating time (opening time. For example, 29.5 seconds for long wins, 0.1 second for short wins or small wins) has passed. If it has elapsed (S708), the big winning opening 71 is closed (S710), and if it has not elapsed, it is determined whether or not the value C of the winning number counter is a predetermined number (S709). If the number is not the number, the big prize opening process is finished, and if the number is the prescribed number, the big prize opening 71 is closed (S710).

  Then, the main control board 20 determines whether or not the value R of the round counter is the maximum number of Rs (S711). If it is not the maximum number of Rs, the big winning opening process is finished. Is started (S712), an ending command is set (S713), and the value R of the round counter is cleared to zero (S714). Ending refers to the period from the end of the final round to the end of the jackpot game. Next, the main control board 20 determines whether or not the ending time has passed (S717). If it has not elapsed, the main winning a prize mouth process is completed, and if it has elapsed, the game state setting process is performed (S718). ), The winning game flag is turned OFF (S719). In the game state setting process, the main control board 20 finishes the game state setting process if the hit game just ended is a small hit, so the game state is not changed, and if it is 15R normal big hit, transitions to the short-time game state. If the 15R probability variation jackpot is turned ON, the probability variation game flag is turned ON to make a transition to the probability variation gaming state. If the 2R latent probability jackpot is made, the latent probability game flag is made to transition to the latent probability gaming state. Turn on.

  On the other hand, when the main control board 20 determines in step S702 that it is not opening, it determines whether or not the special winning opening 71 is ending (S715). If it is ending, the process proceeds to step S717. If it is not ending, it is determined whether or not the special winning opening 71 is in operation (S716). If not in operation, the process proceeds to step S705, and if in operation, the process proceeds to step S708.

  [Electric Chu Process] As shown in FIG. 17, in the electric chew process, the main control board 20 determines whether or not the auxiliary game flag is ON (S801). On the other hand, if it is determined to be ON, it is determined whether or not the opening / closing members 76 and 83, that is, the solenoid 112 is operating (S802). If not, the opening and closing members 76 and 83 are activated according to the current gaming state. Select a pattern (in this embodiment, if the game state is normal or latent game state, release 0.15 seconds once, and if the game is short-time game state or probability change game state, release 1.80 seconds is three times) (S803 ), The operation according to the operation pattern is started (S804). Next, the main control board 20 determines whether or not the operation time (in the operation pattern including a plurality of releases, includes an interval time between the releases) (S805). If the process is finished and the time has elapsed, the auxiliary game flag is turned off (S806), and the electric chew process is finished.

(5) Operation of the start winning device 5 Next, the operation of the start winning device 5 of the pachinko gaming machine 1 configured as described above will be described. First, the operation when the game is played normally will be described, and then the operation when the opening and closing members 76 and 83 are forcibly opened will be described.

(A) Operation in the case of a normal game The player operates the handle 11 to play a game ball so that the fired game ball rolls and falls on the left side portion 3a (see FIG. 1) of the game area 3. A game ball rolling and falling on the left side portion 3 a of the game area 3 can pass through the gate 8. When the game ball passes through the gate 8, the main control board 20 obtains a winning random number on the condition that the number of reserved gaming balls that have passed through the gate 8 is less than four (see S301 to S304), and determines the winning random number. Processing is performed (see S605). In the winning random number determination process, when it is determined that the winning random number corresponds to the predetermined winning random number value, the normal symbol is displayed in a variable manner on the normal symbol display 13, and then the normal symbol is stopped at the winning symbol and the auxiliary game is executed. (Refer to S608 to S612 and electric Chu processing).

  In the case of an auxiliary game in the normal game state or in the latent game state (see the electric Chu process), the main control board 20 energizes the solenoid 112 once for 0.15 seconds (see S804). When the solenoid 112 is energized, the opening and closing members 76 and 83 are opened as shown by the two-dot chain line in FIG. 2, but the opening time of the opening and closing members 76 and 83 is as short as 0.15 seconds. The winning to the second starting port 51b is hardly expected.

  On the other hand, if the auxiliary game is in the short-time gaming state or the probability-changing gaming state (refer to the electric Chu process), the main control board 20 energizes the solenoid 112 once for 1.80 seconds three times ( (See S804). In this case, since the opening time of the opening and closing members 76 and 83 is as long as 1.80 seconds and the number of times of opening is three times, it is possible to sufficiently expect the winning of the game ball to the second starting port 51b.

  When the game ball wins the second start port 51b, a predetermined number of award balls (for example, four award balls) are paid out by a payout device (not shown), and the main control board 20 wins the second start port 51b. Various random numbers including jackpot random numbers are acquired on condition that the number of reserved game balls is less than four (see S206 to S209), and jackpot determination processing is performed (see S407). Even when the game ball wins the first start opening 51a, the main control board 20 similarly acquires a jackpot random number (see S201 to S204) and performs a jackpot determination process (see S407). When it is determined that the acquired jackpot random number corresponds to a predetermined jackpot random number value in the jackpot determination process, the second special symbol display 14b (the first special symbol display 14a when winning based on the first start port 51a is based) ), The special symbol is displayed in a variable manner, and the display unit 4a performs a variation display of the decorative symbol and a reach effect. Then, the special symbol is changed and stopped at the set jackpot symbol, and the jackpot is generated in the display unit 4a. A message to that effect is displayed, and a jackpot game (see the big prize opening process) is executed.

  When the jackpot game is executed, the grand prize winning hole 71 is intermittently opened for a predetermined number of rounds, and when a game ball wins the opened big winning prize hole 71, a predetermined number (for example, 13) of prize balls are paid out. . For example, when a 15R normal jackpot is won, the big winning opening 71 is intermittently opened for 15 rounds (see S704 to S711). After that, it shifts to the short-time gaming state (see S718).

  Here, the opening operation of the opening and closing members 76 and 83 that are frequently opened during the short-time gaming state will be described in detail with reference to FIGS. 6 and 7 show only the left opening / closing member 76, the right opening / closing member 83 operates symmetrically with the left opening / closing member 76. The same applies to the description of other members (for example, the linking member 122) provided in the start winning device 5. As shown in FIG. 6A, when the solenoid 112 is in a non-excited state, the open / close members 76 and 83 are in a state in which the second start port 51b is closed. That is, the plunger 114 is in a state protruding forward, and the connecting member 122 is in a state where the front end portions 124 and 129 are inclined downward. Therefore, the opening / closing members 76 and 83 are connected to the connecting shaft 78 of the left opening / closing member 76 and the connecting shaft of the right opening / closing member 83 by the front end portion 124 of the left arm portion 123 and the front end portion 129 of the right arm portion 128 of the connecting member 122. 85 are pushed down, and the inner side surfaces 76c and 83c are in a closed state along the vertical surface.

  At this time, since the plunger 114 protrudes forward, the shutter piece 142 pivotally supported by the plunger cover 135 has the lower portion 145 attached to the front surface 145a thereof and the winning ball passing hole 50 of the mounting board portion 48. The game ball is in a state where it can be prevented from rolling from the second ball passage portion 69 to the third ball passage portion 99. The second compression coil spring 119 is compressed between the plunger cover 135 and the sliding member 116.

  When the solenoid 112 is excited, as shown in FIG. 6B, the opening / closing members 76 and 83 are displaced to a state where the second starting port 51b is opened. That is, when the solenoid 112 is excited, the plunger 114 is attracted to the solenoid body 113 and moves rearward, and accordingly, the second compression coil spring 119 and the sliding member 116 are moved to the plunger cover 135. The connecting member 122 swings so that the front end portions 124 and 129 are raised upward about the swinging shafts 126 and 131 along the left-right direction. Accordingly, the connecting shaft 78 of the left opening / closing member 76 and the connecting shaft 85 of the right opening / closing member 83 are lifted by the front end portion 124 of the left arm portion 123 of the connecting member 122 and the front end portion 129 of the right arm portion 128. The opening / closing members 76 and 83 swing in the direction in which the distal end portions 76b and 83b are separated from each other, thereby opening the second starting port 51b.

  At this time, as the plunger 114 moves rearward, the shutter piece 142 pivotally supported by the plunger cover 135 brings the rear surface 142a into sliding contact with the front end 109 of the horizontal protrusion 108, It pivots upward about a pivot shaft 144 along the horizontal direction. As a result, the shutter piece 142 is placed on the upper surface 108b of the horizontal protrusion 108, and the restriction of passage of the winning ball passage hole 50 in the attachment board 48 is released, and the game ball that has won the second starting opening 51b is It is possible to roll from the second ball passage portion 69 to the third ball passage portion 99. Note that the game ball rolling from the second ball passage portion 69 to the third ball passage portion 99 passes through the detection hole portion 55 and is detected by the second start port SW54b, as shown in FIG. It is discharged downward.

  When the solenoid 112 returns to the non-excited state, the front member 114b is pushed by the sliding member 116 and the sliding member 116 via the second compression coil spring 119 by the forward biasing force of the first compression coil spring 118. Both jars 114 return to the initial position, and accordingly, the shutter piece 142 returns to the state where the winning ball passing hole 50 is blocked from the rear (see FIG. 6A).

(B) Operation when the opening and closing members 76 and 83 are forcibly opened Next, the case where the opening and closing members 76 and 83 are forcibly opened due to fraud will be described. First, a case where the opening / closing member is forcibly opened when the solenoid 112 is not operated (when the opening / closing members 76 and 83 are closed) will be described. When the open / close members 76 and 83 in the closed state shown in FIG. 6A are forcibly opened using a wire or the like even though the solenoid 112 is not operated, as shown in FIG. The connecting member 122 engaged with the connecting shafts 78 and 85 of the opening and closing members 76 and 83 swings upward with the swinging shafts 126 and 131 extending in the left-right direction as the swing center, and thereby the connecting member. The sliding member 116 engaged with 122 slides rearward along the shaft portion 114 a of the plunger 114 against the urging force of the first compression coil spring 118.

  However, even if the opening and closing members 76 and 83 are forcibly opened in this way, the solenoid 112 is in an inoperative state, and the plunger 114 is not displaced while protruding forward. Accordingly, the shutter piece 142 is in a state of closing the winning ball passing hole 50 from the rear as shown in FIG. For this reason, even if the second starting port 51b is forcibly opened to win a game ball, the winning ball to the second starting port 51b is blocked by the shutter piece 142 and the winning ball through hole 50 is opened. It cannot pass through and is not detected by the second start port SW54b. Therefore, since the jackpot random number is not acquired and the winning ball is not performed, even if such a second opening 51b is forcibly opened, there is no profit for the fraudster. Therefore, according to the pachinko gaming machine 1 of the embodiment, it is possible to suppress such an illegal act.

  Next, the case where the open / close members 76 and 83 are forcibly held in the open state when the solenoid 112 is operated (when the open / close members 76 and 83 are opened) will be described. If the open / close members 76 and 83 in the open state shown in FIG. 6B are forcibly held in the open state using wires or the like, the solenoid 112 becomes inoperative and the adsorption force to the plunger 114 is reduced. Even if it disappears, the first compression coil spring 118 remains compressed and does not return. That is, when the opening and closing members 76 and 83 are forcibly held in the open state, the connecting member 122 connected to the opening and closing members 76 and 83 is held in a posture that swings upward and engages with the connecting member 122. Since the sliding member 116 is held in the rear position, the first compression coil spring 118 cannot be returned while being compressed.

  However, the plunger 114 and the sliding member 116 are slidable with each other, and the compressed second compression coil spring 119 is mounted between the plunger cover 135 and the sliding member 116. Only the plunger 114 returns to the front (initial position) by the restoring force of the second compression coil spring 119. Therefore, even when the open / close members 76 and 83 are forcibly held in the open state in the open state, the plunger 114 is moved to the initial position as shown in FIG. Since the winning ball passing hole 50 is closed by the shutter piece 142, the game ball is blocked by the shutter piece 142 even if the second starting port 51 b is forcibly held to win the game ball. And cannot pass through the winning ball passing hole 50 and is not detected by the second starting port SW54b. Therefore, since the jackpot random number is not acquired and the winning ball is not performed, even if such a second opening 51b is forcibly opened, there is no profit for the fraudster. Therefore, according to the pachinko gaming machine 1 of the embodiment, it is possible to suppress such an illegal act.

(6) Effects of the Embodiment As described above, in the pachinko gaming machine 1 according to the embodiment, the start winning device 5 allows the game ball that won the second start port 51b to reach the second start port SW54b. The shutter piece 142 includes a shutter piece 142 that can be stopped. The shutter piece 142 is driven by a solenoid 112, and when the solenoid 112 is not in operation, a game ball that has won a prize at the second start port 51b is passed from the second ball passage portion 69 to the third ball passage portion. When the solenoid 112 is actuated, the game ball that has won the second start port 51b is prevented from rolling from the second ball passage portion 69 to the third ball passage portion 99. Allow.

  Therefore, even if the opening and closing members 76 and 83 are forcibly opened and a game ball is won in the second start port 51b, if the solenoid 112 is not activated, the win ball is detected by the second start port SW54b. Since it is blocked on the second ball passage portion 69 before being detected and detected by the second starting port SW54b, the game ball is not counted as a winning ball, and no big hit random number is obtained or a winning ball is not performed. Therefore, even if the game ball is illegally won by forcibly opening the opening and closing members 76 and 83, there is no profit for the fraudster. Therefore, the act of forcibly opening the opening and closing members 76 and 83 and illegally winning the game ball is prevented. be able to.

  In the pachinko gaming machine 1 according to the embodiment, the sliding member 116 is fitted to the plunger 114 that moves forward and backward, and the opening and closing members 76 and 83 have the sliding member 116 in the forward position (see FIG. 6A). The second starting port 51b is closed when the sliding member 116 is located, and the sliding member 116 is opened via the connecting member 122 so that the second starting port 51b is opened when the sliding member 116 is at the rear position (see FIG. 6B). It is connected to. The shutter piece 142 restricts the game ball from passing through the second ball passage portion 69 when the plunger 114 is in the forward movement position (see FIG. 6A), and the plunger 114 is in the backward movement position (see FIG. 6). The ball is connected to the plunger 114 via the plunger cover 135 so as to allow the game ball to pass through the second ball passage portion 69 when in (b). When the solenoid 112 is not in operation, the plunger 114 is in the forward position regardless of the position of the sliding member 116 (see FIGS. 6A and 7B). Moves backward and the sliding member 116 moves to the rear position (see FIG. 6B).

  Therefore, if the solenoid 112 is not activated, the plunger 114 is in the forward movement position regardless of the position of the sliding member 116, in other words, regardless of whether the opening and closing members 76 and 83 are open or closed. The piece 142 is in a state in which the winning ball can be stopped on the second ball passage portion 69 (see FIGS. 6A and 7B). Therefore, if the solenoid 112 is not in operation, the game ball won in the second start port 51b is not detected by the second start port SW54b. Therefore, the game ball is illegally won by forcibly opening the opening and closing members 76 and 83. There is no profit for the fraudsters. Therefore, the act of forcibly opening the opening / closing members 76 and 83 to illegally win the game ball can be prevented.

  Further, in the pachinko gaming machine 1 according to the embodiment, the plunger 114 biases the sliding member 116 to the front position between the sliding member 116 and the solenoid main body 113 and the plunger via the sliding member 116. A second compression coil spring 118 that biases the plunger 114 to the forward movement position, and a first compression coil spring 118 that biases the plunger 114 to the forward movement position, and between the sliding member 116 and the tip 114b of the plunger 114; 119. A spring having a restoring force smaller than that of the first compression coil spring 118 is used for the second compression coil spring 119.

  Therefore, when the solenoid 112 is inactive, the plunger 114 is biased by the first compression coil spring 118 and the second compression coil spring 119 and is in the advanced position, and the sliding member 116 is also in the second compression coil. Since the restoring force of the spring 119 is smaller than the restoring force of the first compression coil spring 118, the spring 119 is biased by the first compression coil spring 118 and is in the forward position (see FIG. 6A). From this state, when the opening and closing members 76 and 83 are forcibly opened, the sliding member 116 moves backward against the urging force of the first compression coil spring 118, but the plunger 114 is moved to the second compression coil. Since it is urged by the spring 119, it is not displaced in the forward position (see FIG. 7B). When the solenoid 112 is actuated, the plunger 114 and the sliding member 116 move rearward against the urging force of the first compression coil spring 118 and the second compression coil spring 119, and the opening and closing members 76 and 83 are The second start port 51b is opened (see FIG. 6B). Here, when the opening and closing members 76 and 83 are forcibly held with the second start opening 51b opened, the sliding member 116 is also held at the rear position, and the first compression coil spring 118 becomes unrecoverable. . However, since the second compression coil spring 118 can be restored, when the solenoid 112 is deactivated, the plunger 114 is urged by the second elastic member 119 to return to the advanced position (see FIG. 7B). ). As described above, according to the pachinko gaming machine 1 of the embodiment, if the solenoid 112 is not activated, the plunger 114 is always in the forward position, and the winning ball is blocked by the shutter piece 142 on the second ball passage portion 69. Therefore, even if the opening and closing members 76 and 83 are forcibly opened to win the game ball, the winning ball is not detected by the second starting port SW54b. Therefore, even if the game ball is illegally won by forcibly opening the opening and closing members 76 and 83, there is no profit for the fraudster. Therefore, the act of forcibly opening the opening and closing members 76 and 83 and illegally winning the game ball is prevented. be able to.

  The start winning device 5 in the pachinko gaming machine 1 according to the embodiment includes a plunger cover 135, a shutter piece 142, a second compression coil spring 119, and a sliding member 116 in addition to the conventionally used start winning device 5. As a result, the engaging shafts 125 and 131 of the connecting member 122 are engaged with the engaging grooves 116b of the sliding member 116. That is, since it can be manufactured using the conventional start winning device 5 without subjecting the conventional start winning device 5 to complicated processing, the opening and closing members 76 and 83 can be manufactured while keeping the manufacturing cost low. It is possible to configure the start winning device 5 in which measures are taken against forcible opening.

  Further, the pachinko gaming machine 1 according to the embodiment does not hold the opening and closing members 76 and 83 so as not to be opened by fixing the connecting member 122, but uses a member (shutter piece 142) different from the connecting member 122. The rolling of the game ball in the second starting port 51b is restricted, and the detection of the winning game ball in the forcibly opened second starting port 51b is restricted. Therefore, when designing the start winning device 5 that copes with the illegal act of forcibly opening the second start port 51b, the position and position of the solenoid 112 (the plunger 114 and the opening / closing member) are affected by the size and shape of the connecting member 122. It is possible to design using the existing start winning device 5 only by appropriately designing the shutter piece 142 without being influenced by the separation distance (76, 83).
