On condition that the normal symbol starting means 25 composed of a gate or the like detects the game ball, the two light emitters blink alternately for a predetermined time, and the hit determination random number value acquired when the normal symbol starting means 25 detects the game ball In the state where the “◯” side illuminant corresponding to the hit mode emits light when it matches the predetermined hit determination value, and the “×” side illuminant corresponding to the off mode otherwise The flashing stops when is emitted. When the normal symbol is changed and stopped in a winning manner, a normal profit state occurs in which the openable start winning means 27 is opened a predetermined number of times for a predetermined time.

  Further, when the normal symbol starting means 25 detects a game ball during the fluctuation display of the normal symbol display means 22 or during the normal profit state, the hit determination random number value acquired at the time of detection detects a predetermined upper limit hold. The number, for example, four, is stored as a limit, and the normal number-of-holds display means 23 made of, for example, the same number of light-emitting bodies as the maximum number of reserved numbers indicates the number of stored random numbers (hereinafter, the number of normal reservations) for the hit determination by the number of light emission. It is displayed to inform the player of the number of normally reserved items at that time.

  Each of the first and second special symbol display means 24a and 24b is composed of one or a plurality of display means such as a seven-segment type display means capable of variably displaying each one of the first and second special symbols. The first special symbol display means 24 a is based on the winning of the game ball in the first start winning port 41 on the distribution start winning means 26, and the second special symbol display means 24 b is the first special symbol display means 24 b on the distribution start winning means 26. Based on the fact that the game ball wins either the 2 start winning opening 42 or the openable start winning means 27, the first and second special symbols are respectively displayed in a variable manner for a predetermined time, and the first starting winning opening 41 is displayed. , When the jackpot determination random number value acquired at the time of winning the second start winning opening 42 and the openable start winning means 27 coincides with a predetermined jackpot determination value, in a predetermined jackpot mode, otherwise Is in a detachment manner People have become to stop. If any of the first and second special symbols stops after a change in a big win mode, a big win state occurs in which the big winning means 28 is released according to any of a plurality of types of open patterns, for example.

  The first and second special symbols are not composed of, for example, numeric symbols, but are composed of a plurality of types of symbols consisting of combinations of lines and points that have no special meaning as such. A plurality of jackpot modes are set, and the other modes are set to be off.

  Further, when a game ball is won in the first and second start winning openings 41 and 42 and the openable start winning means 27 during the variation display of the first and second special symbols or the big hit state, The acquired jackpot determination random number value or the like is stored up to a predetermined upper limit reserved number, for example, 4 each, and the first and second special reserved number display means 32a and 32b store the number of jackpot determination random number values respectively. (Hereinafter, the number of first and second special reservations) is displayed, and the player is notified of the number of first and second special reservations at that time.

  In the present embodiment, the symbol variation of the first and second special symbol display means 24a and 24b is not started and the symbol variation of one of the first and second special symbol display means 24a and 24b is not performed during the big hit state. Control is performed so that the other symbol variation is not started and both are not varying at the same time. Further, when both the first and second special reserved numbers are 1 or more, the symbol variation of the second special symbol display means 24b is given priority over the symbol variation of the first special symbol display means 24a. Has been.

The convex portions similar to the front guide portions 78a and 79a are on the front cover 80 side (the back side of the front wall of the first and second guide passages 52 and 53), and the concave portions 85 and 86 are on the upper lens body 64 side ( You may provide in the front side in back walls, such as the 1st, 2nd guide passages 52 and 53.

  The vertical ridge portions (passing obstacle portions) 87b and 87c are for obstructing the guidance of the game ball using a magnet by narrowing the front side of the gaps 83b and 83c within a range in which the game ball can pass. The gaps 83b and 83c are arranged in the vertical direction corresponding to at least a part of the gaps 83b (here, approximately 2/3 of the upper side), and are integrally formed on the back side of the front cover 80.

  Further, the lateral protrusions (passing obstacles) 88a and 88b use magnets by narrowing the front side of the gap between the first and second start winning prize ports 41 and 42 within a range in which the game ball can pass. This is for obstructing the guidance of the game ball, and is arranged vertically with a predetermined interval, and at least a part between the first and second start winning holes 41 and 42 (here, approximately 1 / 2 in the left and right directions, and is formed integrally on the back side of the front cover 80.

  In the pachinko machine of the present embodiment, when performing an illegal act (magnet goto) that guides the game ball from the lower side of the game area 15 to the first and second start winning ports 41 and 42 using the magnet through the glass plate 10a. A central path from between the first and second start winning ports 41 and 42 through the gaps 83c and 83b to the upper region of the first and second starting winning ports 41 and 42 and from the right side of the first start winning port 41 There is a right path that reaches the upper region of the first start winning opening 41 through the gap 83d and a left path that passes from the left side of the second start winning opening 42 to the second start winning opening 42 through the gap 83a. Here, in the present embodiment, for the magnetic goto using the left path, the magnetic sensor 50 (see FIG. 1 and the like) arranged on the central start winning unit 17 is used, and the magnet goto using the right path is used. On the other hand, since the magnetic sensor 43 (see FIG. 1) on the adjacent grand prize unit 19 can be detected almost certainly, the horizontal ridge corresponding to the central path far from any of the magnetic sensors 43 and 50. The parts 88a and 88b and the vertical protrusions 87b and 87c are provided.

  The light emitting substrate 66 includes an upper LED 66a disposed on the rear side of the upper lens body 64 and a lower LED 66b disposed on the rear side of the lower lens body 65 on the front side, and the rear sides of the upper and lower lens bodies 64, 65. For example, it is detachably fixed to the base plate 61 by screwing or the like.

  The rear mounting body 63 has a driving case 91 for holding the distribution driving means 55 and the driving lever 90 and a game ball guided rearward by the first and second inclined passage portions 74 and 75 on the rear side of the game board 5. For example, first and second discharge passage portions 92 and 93 that discharge downward, sensor holding portions 94 a and 95 a that hold the first and second game ball detecting means 94 and 95, and magnetic sensor holding that holds the magnetic sensor 50. The unit 50a is integrally provided, for example, and is detachably attached to the rear side of the base plate 61 by screwing or the like.

  The first and second game ball detecting means 94 and 95 detect the game balls won in the first and second start winning ports 41 and 42, and the first and second sensor balls 94a and 95a, for example, It is arranged on the downstream end side of the discharge passage portions 92 and 93.

  The drive lever 90 is for transmitting the driving force of the distribution driving means 55 to the distribution movable body 54. For example, the swing shaft 90a in the front-rear direction is on the lower end side and the drive shaft 70 on the distribution movable body 54 side is on the upper end side. Engaging portions 90b are respectively provided, and an iron plate 90c is fixed along the longitudinal direction thereof, and a first driving posture corresponding to the first sorting posture of the sorting movable body 54 around the swing shaft 90a. And swingable between the second drive posture corresponding to the second sorting posture. It is assumed that the drive lever 90 is elastically biased toward the first drive posture side by biasing means (not shown) such as a coil spring.

  The distribution drive means 55 is constituted by, for example, a magnet coil, and when ON, the iron plate 90c on the drive lever 90 is attracted against the urging force of the urging means, and the drive lever 90 is moved from the first drive posture to the second position. It is made to swing to the driving posture. Thereby, the distribution movable body 54 is held in the first distribution posture when the distribution drive unit 55 is OFF, and is switched from the first distribution posture to the second distribution posture when the distribution drive unit 55 is turned ON. .

  The magnetic sensor 50 is arranged, for example, at the lower left of the second game ball detecting means 95 in consideration of the arrangement position of the magnetic sensor 43 on the special winning unit 19, and is detachably held by the magnetic sensor holding unit 50a. Since the magnetic sensor 50 is affected by a magnet coil or the like, it is desirable to dispose the magnetic sensor 50 at a position as far as possible from the distribution driving means 55 in order to eliminate erroneous detection.

  In the pachinko machine of the present embodiment, there is a route to enter the ball entrance 51 from the warp entrance 36 through the stage 38, and so on, so that the left down route is more than the game ball that has flowed down the right down route 35b. It is assumed that the game ball that has flowed down 35a can enter the entrance entrance 51 with a higher probability.

  FIG. 9 is a block diagram of the control system of this pachinko machine. In FIG. 9, 101 is a main control board, 102 is an effect control board, and each of these control boards 101, 102 collects the central display unit 16 mounted on the game board 5 and a plurality of other game parts from the back side. The board case is detachably mounted at appropriate places on the back side of the gaming machine main body 1 including the inner frame 4 and the game board 5 such as the back side of the back cover.

  The main control board 101 is mainly for performing control related to the game operation on the game board 5 side, and includes a normal random number generation processing means 111 composed of a CPU, a ROM, a RAM, etc., a normal start port check processing means 112, Normal random number storage means 113, normal symbol processing means 114, normal symbol display control means 115, normal profit state generation means 116, first and second special random number generation processing means 121a and 121b, and first and second special start port check processing Means 122a, 122b, first and second special random number storage means 123a, 123b, first and second special symbol processing means 124a, 124b, first and second special symbol display control means 125a, 125b, jackpot state generating means 126 Probability game state generating means 127, time-short game state generating means 128, control command transmitting means 129, and the like are provided.

  The normal random number generation processing unit 111 is configured to repeatedly generate a hit determination random number or the like used for determining whether or not the changed normal symbol is set as a hit state at predetermined time intervals. The normal starting port check processing means 112 performs processing based on the detection of the game ball by the normal symbol starting means 25. The normal random number generation processing means 111 is based on the fact that the normal symbol starting means 25 detects the game ball. One hit determination random number value is created, and the hit determination random number value is stored in the normal random number storage means 113 with a predetermined upper limit reserved number (for example, four) as a limit.

  The normal symbol processing means 114 performs processing related to the normal symbol fluctuation display. The normal symbol display means 22 is in a variable displayable state, and one or more hit determination random number values are stored in the normal random number storage means 113. The winning judgment random number stored in the ordinary random number storage means 113 is retrieved first, and the winning judgment random number matches the predetermined hit judgment value. A hit determination function that makes a hit / miss determination according to whether or not to perform, a normal stop symbol selection function that selects the type of stop symbol after a normal symbol change based on a hit / fail determination result, and a normal symbol change A variable time selection function for selecting time is provided.

  In the present embodiment, as shown in FIG. 10, the hit probability (for example, 1 / 1.3) in the short-time gaming state (hereinafter referred to as “high base time”), which will be described later, Is set higher than the probability of hitting (for example, 1/10), and the variation time at the high base (for example, 2.7 seconds) is shorter than the variation time at the low base (for example, 27 seconds). Is set.

  The normal symbol display control means 115 controls the display of the normal symbol display means 22 based on the normal symbol processing by the normal symbol processing means 114. The normal symbol display means 22 is in a state in which the normal symbol display means 22 can be variably displayed and the normal random number storage means. 113, the normal symbol display means 22 starts to change the normal symbol on the condition that one or more hit determination random number values are stored (the normal holding number is 1 or more), and the normal symbol processing means 114 Based on the elapse of the selected variation time, the variation of the normal symbol is stopped at the stop symbol selected by the normal symbol processing means 114.

  The normal profit state generating means 116 is the open / close means of the open / close-type start winning means 27 when the determination result by the normal symbol processing means 114 is a hit determination and the stop symbol after the fluctuation of the normal symbol display means 22 is in a hit state. 47 is changed to an open state in accordance with any of a plurality of types of opening / closing patterns. In the present embodiment, as shown in FIG. 10, the normal opening / closing pattern (for example, 0.2 seconds × opening once) and the opening time and / or the number of opening times are set to be longer than the normal opening / closing pattern. Two types of open / close patterns (for example, 2 seconds × 3 times open) are set, and a normal open / close pattern is selected when the base is low, and an extended open / close pattern is selected when the base is high.

  The first and second special random number generation processing means 121a and 121b receive a jackpot determination random number used for determining whether or not the first and second special symbols after change are to be a big hit mode, and the special symbols after change are jackpots. It is configured to perform a special random number generation process that repeatedly generates a predetermined random number, such as a jackpot symbol random number used to select a stop symbol when it becomes an aspect, a variation pattern selection random number used to select a variation pattern of a special symbol .

  The first and second special start opening check processing means 122a and 122b perform processing based on the winning of game balls to the first and second start winning opening 41 and 42 and the openable start winning means 27. The special start port check processing means 122a has one jackpot determination random number value and one jackpot symbol random value created by the first special random number creation processing means 121a based on the winning of the game ball in the first start winning opening 41. The jackpot determination random number value and the jackpot symbol random number value are stored in the first special random number storage means 123a with a predetermined upper limit holding number (for example, four each) as a limit, and the second special start opening check process The means 122b is created by the second special random number creation processing means 121b based on the winning of the game ball in either the second start winning opening 42 or the openable start winning means 27. One winning determination random number value and one jackpot symbol random number value are acquired one by one, and the second special random number storage means 123b limits the jackpot determination random number value and the jackpot symbol random number value to a predetermined upper limit holding number (for example, four each). It is comprised so that it may memorize.

  The first and second special symbol processing means 124a and 124b perform processing related to the variable display of the first and second special symbols, and the first and second special symbol display means 24a and 24b are in a state capable of variable display. The first and second special random number storage means 123a and 123b are stored on the condition that one or more jackpot determination random numbers are stored (the first and second special reserved numbers are one or more). , The jackpot determination random number value stored earliest in the second special random number storage means 123a, 123b is taken out, and whether the jackpot determination random number value matches a predetermined jackpot determination value or not is determined. The jackpot determination function, the determination result of the jackpot / losing, and the jackpot symbol random number value stored together with the jackpot determination random number value in the first and second special random number storage means 123a, 123b, Based on the special stop symbol selection function for selecting the stop symbol after the fluctuation of the first and second special symbols based on the determination result of jackpot / losing, a plurality of special types as the variation patterns of the first and second special symbols A first and second variation pattern selection function for selecting one of the symbol variation patterns is provided.

  Further, for example, during the big hit state, the first and second special symbol display means 24a and 24b do not start changing the symbol, and during either one of the first and second special symbol display means 24a and 24b, the symbol changes. When the other symbol variation is not started, both are controlled so as not to be varied at the same time, and the first and second special reserved numbers are both 1 or more, the first special symbol display means 24a. It is controlled so that the symbol variation of the second special symbol display means 24b is given priority over the symbol variation.

  The first and second special symbol display control means 125a and 125b perform display control of the first and second special symbol display means 24a and 24b. The first special symbol processing means 124a or the second special symbol processing means 124b. Based on the special symbol processing by, the first special symbol display means 24a or the second special symbol display means 24b starts the fluctuation of the first and second special symbols and the fluctuation corresponding to the predetermined first and second fluctuation patterns Based on the passage of time, the fluctuation of the first and second special symbols is stopped at a predetermined stop symbol.

  The big hit state generating means 126 is for generating a big hit state in which the big win means 28 is opened in accordance with a predetermined opening pattern, and the determination result of the big hit / out by the first and second special symbol processing means 124a and 124b is a big hit. Based on the fact that the stop symbol after the change of the first and second special symbols becomes a jackpot mode, a jackpot state in which the big winning means 28 is opened according to a predetermined opening pattern is generated. For example, a plurality of types of opening patterns of the big winning means 28 in the big hit state are prepared, and one of them is selected according to the type of the big win mode.

  In this embodiment, as shown in FIG. 11, two types of 3R opening pattern and 15R opening pattern are provided as the opening patterns of the big winning means 28, and the big hit state generating means 126 is the first and second special winning means 126. When the symbol stop pattern is the jackpot mode 1 or 3, the 3R opening pattern is selected, and when the jackpot mode 2 or 4, the 15R opening pattern is selected. Here, the 3R opening pattern is closed on the condition that a predetermined time (in this case, 30 seconds) has elapsed since the opening of the big winning means 28 or a predetermined number (for example, 9) of game balls have won. The opening / closing operation is set to repeat three rounds. The 15R opening pattern is set so that the same opening / closing operation as the 3R opening pattern is repeated 15 rounds.

  In the present embodiment, the selection rates of the two types of open patterns in the big hit state are exactly the same for the first special symbol and the second special symbol. That is, in the present embodiment, there is no difference between the case where the first special symbol display means 24a changes and the case where the second special symbol display means 24b changes regarding the expected value of the number of prize balls paid out by one big hit.

  The probability variation gaming state generating means 127 generates a probability variation gaming state in a predetermined period after the occurrence of the jackpot state. For example, the probability variation gaming state is generated or not generated for a predetermined period according to the type of the jackpot mode. ing.

  During the probable gaming state, the number of jackpot determination values increases compared to other low-probability states, so that the probability that the first and second special symbols will be jackpots is low to high (for example, 1/350). The probability (for example, 1/35) can be switched. In the present embodiment, as shown in FIG. 11, regardless of whether the first special symbol or the second special symbol is low base time or high base time, the jackpot mode 1 or 2 is applied during the gaming state. When a jackpot state occurs, a probable gaming state occurs after the end of the jackpot state, and continues until, for example, the next jackpot state occurs.

  The short-time gaming state generating means 128 generates a short-time gaming state in a predetermined period after the occurrence of the jackpot state. For example, the short-time gaming state is generated or not generated for a predetermined period according to the type of the big hit mode. ing.

  During the short-time gaming state (that is, at the time of high base), the variation time of the first and second special symbols is switched to a shortened variation time shorter than the normal variation time, respectively. Open / close start winning means from low probability (for example 1/10) to high probability (for example 1 / 1.3), change time from normal change time (for example 27 seconds) to shortened change time (for example 2.7 seconds) The open / close pattern of the 27 open / close means 47 can be switched from a normal open / close pattern (for example, 0.2 seconds × 1 open) to an extended open / close pattern (for example, 2 seconds × 3 open). In the present embodiment, a plurality of types of durations in the short time state are provided, and are set until the first and second special symbols fluctuate a predetermined number of times or until the next jackpot state occurs. .

  In the example of FIG. 11, regarding the first special symbol, after the jackpot state that occurs at the time of low base, the short-time gaming state does not occur regardless of the type of jackpot mode, and at the time of high base, the jackpot according to the jackpot mode 1 or 2 When a state occurs, the short-time gaming state until the next jackpot after the end of the state, and when the big hit state according to the jackpot mode 3 or 4 occurs, the short-time gaming state until the symbol fluctuates 55 times after the end In addition, regarding the second special symbol, regardless of the low base time and the high base time, when the big hit state by the big hit mode 1 or 2 occurs, the short-time gaming state until the next big jackpot after the end, When a big hit state according to jackpot mode 3 or 4 occurs, a short game state occurs until the symbol changes 55 times after the end It is sea urchin set.

  As described above, in the example of FIG. 11, the difference between the first special symbol and the second special symbol is only the setting contents relating to the occurrence of the short-time gaming state after the end of the jackpot state occurring at the low base, After the jackpot state that occurs at base time is over, even if the first special symbol becomes a jackpot, no short-time gaming state occurs, whereas when the second special symbol becomes a jackpot, Depending on the type, a short game state will always occur for a certain period of time. If the short-time gaming state occurs, it becomes easy to win a game ball to the openable start winning means 27, and the expected value of the number of prize balls paid out in a certain period increases due to an increase in the number of symbol fluctuations per certain time. However, it becomes a more advantageous state for the player. That is, in the present embodiment, the probability of occurrence of the short-time gaming state after the end of the jackpot state that occurs at low base is set higher on the second special symbol side than on the first special symbol side. When the second special symbol display means 24b changes, the expected value of the number of prize balls to be paid out is larger than when the special symbol display means 24a changes, which is more advantageous for the player.

  The control command transmission means 129 is for transmitting a predetermined control command to the sub-control board side such as the effect control board 102 by one-way communication to give a control command. The first and second special symbol processing means 124a, Based on the first and second special symbol processing by 124b, a variation pattern designation command for designating a variation pattern of the first and second effect symbols, a stop symbol designation command for designating a stop symbol of the first and second effect symbols, A function for transmitting a variable stop designation command for designating a variable stop for the first and second effect symbols to the effect control board 102 side, a first and a second special reserve number designation command for designating the first and second special reserve numbers In addition to the function of transmitting the game state command to the effect control board 102 side, a function of transmitting a game state command to the effect control board 102 side when the game state changes is provided.

  The effect control board 102 controls various effect means such as the first and second effect symbol display means 31a and 31b, the first and second special reserved number display means 32a and 32b, the sound output means 131, and the lamp means 132. Provided with special reserved number display control means 133, effect symbol display control means 134 and the like.

  The special reserved number display control means 133 performs display control of the first and second special reserved number display means 32a and 32b, and is based on the first and second special reserved number designation commands transmitted from the main control board 101. Thus, the first and second reserved display images X and Y corresponding to the first and second special reserved numbers are displayed at predetermined positions on the display screen 21a of the image display means 21.

  The effect symbol display control means 134 controls the display of the first and second effect symbol display means 31a, 31b and the accompanying sound output means 131, the lamp means 132, etc., and the variation pattern from the main control board 101 side. When a designation command is received, on the display screen 21a of the image display means 21 based on the variation pattern corresponding to the variation pattern designation command, the variation of the first effect symbol or the second effect symbol is started and the change stop designation is specified. When the command is received, the variation of the first effect symbol or the second effect symbol is stopped in the stop symbol mode selected based on the stop symbol designation command, and the variation display of the first and second effect symbols is adjusted. Then, a predetermined sound effect is output from the sound output means 131, and the lamp means 132 is made to emit light in a predetermined pattern.

  In the pachinko machine of the present embodiment configured as described above, as shown in FIG. 11, the probability of occurrence of the short-time gaming state after the end of the jackpot state occurring at the time of low base is higher than that of the first special symbol side. Since the symbol side is set higher, the expected value of the number of prize balls to be paid out in a certain period when the second special symbol display means 24b fluctuates than when the first special symbol display means 24a fluctuates. Can be said to be more advantageous for the player. However, when the base is low (except during the short-time gaming state), the probability that the normal symbol display means 22 will be a hit state is low, and even if the normal profit state occurs due to the hit state, the opening / closing start winning means 27 is opened. Since the time is short (FIG. 10), the possibility of winning the openable start winning means 27 is extremely low. Therefore, in the pachinko machine according to the present embodiment, at the time of low base, the left-handed path is left-handed rather than the right-handed aiming means 25 and the open-type start winning means 27 on the right-falling path 35b side. It is advantageous for the player to aim for winning from the 35a side to the first and second start winning openings 41 and 42 through the sorting entrance 51.

  The player makes a left turn at a low base, and the game ball enters the entrance entrance 51 from the central drop part 37 through the warp entrance 36 and the stage 38 from the left flow path 35a or the stage 38 etc. If the game ball is guided by the game nail or the like without entering the ball and enters the distribution entrance 51, the game ball is guided by the convex portion 84 and the concave portion 67 and meanders backward, and the distribution movable body 54 is sufficiently decelerated. It falls down (Fig. 6).

  The distribution movable body 54 is switched between the first distribution posture and the second distribution posture by the driving of the distribution drive means 55, for example, in a constant pattern or a different pattern depending on the gaming state. The game balls are distributed to the first guide passage 52 and the second guide passage 53 in accordance with the timing at which the game balls enter the mouth 51. That is, for example, the game ball that has entered the distribution entrance 51 during the period from the second distribution posture (indicated by a one-dot chain line in FIG. 5) to the first distribution posture (indicated by a solid line in FIG. 5). 5 is guided to the first guide passage 52 when the sorting movable body 54 is in the first sorting posture, as shown by a solid line arrow in FIG. 5, and for example, the sorting movable body 54 is second from the first sorting posture. A game ball that has entered the distribution entrance 51 during the period until the distribution posture is reached, as indicated by the two-dot chain line arrow in FIG. Guided to the passage 53 side.

  As shown in FIGS. 6 and 7, the game ball guided to either the first or second guide passage 52 or 53 is guided in front of the downstream end of the first or second guide passage 52 or 53, respectively. It is guided by the parts 78a and 79a and the recesses 85 and 86 and falls on the first and second start winning ports 41 and 42 while meandering forward. At this time, since the game balls meander forward and the lateral movement is suppressed, the possibility of jumping out from the gaps 83a to 83d is low, and the first and second start winning holes 41, Win 42.

  The game ball won in the first start winning port 41 is guided to the back side of the game board 5 through the winning ball discharge port 72, the first inclined passage portion 74, and the first discharge passage portion 92, and at that time, the first game It is detected by the sphere detection means 94. In addition, the game ball won in the second start winning opening 42 is guided to the back side of the game board 5 through the second winning ball discharge port 73, the second inclined passage portion 75, and the second discharge passage portion 93. Is detected by the second game ball detecting means 95.

  When the first start winning opening 41 is won, the first special symbol display means 24a is changed based on that, and when the second start winning opening 42 is won, the second special symbol display means 24b is changed based on the first special symbol displaying means 24b. However, when both the first and second special reserved numbers are 1 or more, the symbol variation of the second special symbol display means 24b is given priority over the symbol variation of the first special symbol display means 24a. Is called.

  As described above, in the pachinko machine of the present embodiment, even when the base is low, not only the first start winning opening 41 related to the start of fluctuation of the first special symbol display means 24a but also the second more advantageous for the player. Since the winning to the second start winning opening 42 related to the start of variation of the special symbol display means 24b can also be expected, it is clearly different depending on the gaming state whether so-called right-handed or left-handed is advantageous for the player. Therefore, a variety of game development can be expected.

  When the stop symbol after the change of the first and second special symbol display means 24a, 24b becomes a big hit mode, a big hit state where the big winning means 28 is released occurs, so that the player is on the right flow path 35b. The right winning means 28 may be switched to the right hand.

  When the first special symbol display means 24a becomes a big hit mode and a big hit state occurs, the probability variation gaming state is generated with a probability of 80%, but the short-time gaming state does not occur (FIG. 11). Since the low-base game continues thereafter, the player switches to left-handed again after the end of the big hit state.

  On the other hand, when the second special symbol display means 24b is in a big hit mode and a big hit state occurs, a short-time gaming state always occurs (FIG. 11), so the game is played on a high base after the big hit state ends. . Therefore, the player makes a right-hand hit during the big hit state and aims at the normal symbol starting means 25 and the open / close-type starting winning means 27 on the right flow down path 35b, so that the player can play the game more advantageously than when the base is low. It can be carried out.

  In addition, when a so-called magnet got is performed on the pachinko machine aiming at the first and second start winning ports 41 and 42, the gaps 83c and 83b are passed between the first and second start winning ports 41 and 42. A central path that leads to the upper area of the first and second start winning openings 41, 42, a right path that passes from the right side of the first start winning opening 41 to the upper area of the first start winning opening 41 via the gap 83d, and a second path There is a left-side path from the left side of the start winning port 42 to the second start winning port 42 through the gap 83a.

  Here, for example, the right path is close to the magnetic sensor 43 on the big winning unit 19, and the left path is close to the magnetic sensor 50 on the central start winning unit 17, so if the magnet approaches those paths, Even when the magnetic force is weak, the magnetic sensors 43 and 50 can reliably detect the magnetic force. On the other hand, since the central path is far from both of the magnetic sensors 43 and 50, for example, when a relatively weak magnet is used that can somehow attract one game ball through the glass plate 10a, the magnetic sensors 43 and 50 are used. None of these may be detected.

  However, in this pachinko machine, the horizontal ridges 88a and 88b are arranged between the first and second start winning ports 41 and 42, and the vertical ridges 87c and 87b are arranged corresponding to the gaps 83c and 83b. As shown in FIG. 8, the distance between the magnet and the game ball is increased when the game ball guided by the magnet gets over the protrusions 88a, 88b, 87c, 87b. As a result, when a weak magnet that cannot be detected by the magnetic sensors 43 and 50 is used, it becomes difficult to get over the protrusions 88a, 88b, 87c, and 87b while adsorbing the game balls. Can be effectively blocked.

  Further, in this pachinko machine, when the distribution driving means 55 is OFF, the distribution movable body 54 has a first distribution posture that is disadvantageous for the player among the first distribution posture and the second distribution posture (the solid line in FIG. 5). For example, when the harness connected to the distribution driving means 55 is intentionally disconnected, all the game balls that have entered the distribution entrance 51 are first started. It is guided to the winning opening 41 side, and winning to the second starting winning opening 42 which is more advantageous for the player can be prevented.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the example in which the protrusions 88a, 88b, 87c, and 87b as examples of the passage obstructions are provided in the front cover 80 so as to protrude rearward, the passage obstructions need not necessarily be provided in the front cover. As long as a path that can be used for guiding a game ball using a magnet (hereinafter referred to as a guide path) is narrowed to the front side of the guide path within a range in which the game ball can pass. .

  FIG. 12 shows an arrangement example of the passage obstruction part when the front cover corresponding to the guide route is not provided. In this example, rod-like passing obstacles 88a and 88b are connected between the first start winning opening 41 and the second starting winning opening 42 so as to connect the front end sides of the first and second starting winning openings 41 and 42. And a rod-shaped passage obstruction portion so as to connect the front end sides of the first and second guide passages 52 and 53 and the first and second start winning ports 41 and 42 corresponding to the gaps 83c and 83b, respectively. 87c and 87b are installed.

  Further, the passage obstruction part may be arranged in a minimum range over which the game ball guided by the magnet through the glass plate 10a and passing through the guidance path always gets over. For example, as shown in FIG. Alternatively, one or a plurality of dot-like projections (passage obstructions) 135b, 135c, 136a, 136b may be arranged.

  In the embodiment, the right path on the right side of the start winning opening 41 and the left path on the left side of the second start winning opening 42 are not provided with a passage obstruction because the distance from the magnetic sensor is short. For example, a passage obstruction part may be provided in the gaps 83d and 83a.

  The distribution means for distributing the game balls entering the distribution entrance 51 to the plurality of guide passages may not be a movable body, and for example, one or a plurality of game nails may be used as the distribution means. Moreover, you may comprise so that a game ball may be distributed to three or more guide passages by a distribution means.

  In the embodiment, an example is shown in which a passing obstacle portion is provided for a winning opening on the sorting start winning means 26 provided with a sorting means on the upstream side. Of course, a passing obstacle portion is provided for other entrances. May be provided.

  The present invention is not limited to pachinko machines and can be similarly implemented in various ball game machines such as an arrangement ball machine and a sparrow ball game machine.
