Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a ball game machine that can change the flow of a game ball by tilting a nail planted on the game board. is there.

  Conventionally used ball game machines such as pachinko machines have been devised to prevent the player from getting bored by changing the winning rate during the game. In particular, a ball game machine having a variable winning device that changes the winning rate of a game ball at the time of a game to enhance the interest of the game is known.

  A variable winning device provided in a ball game machine is arranged on a game board together with a plurality of nails. For example, as proposed in Patent Document 1, above the winning opening of the variable winning device. Is provided with a pair of left and right variable blades.

The variable winning device described in Patent Document 1 has a configuration as shown in FIGS. 19 (A) and 19 (B).
Specifically, a variable winning device is disposed at the left and right positions of the start winning port 112 for starting the variable display of the symbols in the image display device (not shown) on condition that a game ball is won, and a pair of left and right blades The variable winning device is composed of a blade body 111A constituted by members. The blade tip 111B indicates the tip of the blade 111A.

FIGS. 19A and 19B show the state of the variable winning device 111 and the flow of the game ball at the time of opening (A) and the time of closing (B), respectively.
As shown in FIG. 19A, when the variable winning device 111 is opened (A), the flow of game balls is indicated by arrows A, B, C, and D, and the start winning port 112 and the normal symbol starting port A part of the game ball that has flowed down during 110 flows into the start winning opening 112. A part of the game ball that has not flowed into the start winning port 112 collides with the blade tip 111B on the normal symbol start port 110 side and is ejected obliquely upward in the direction of arrow D.

  The bullets that have been bulleted flow into the upper position of the normal symbol starting port 110 from between the two obstacle nails 131a and the obstacle nails 131b that are arranged above and below, and are bulleted by the obstacle nail 131c. It flows into the start port 110.

JP 2004-81243 A

  However, in the bullet ball game machine having the variable winning device 111 described in Patent Document 1, the variable winning device 111 is configured by a pair of left and right blade bodies 111A. For this reason, in order to open and close the blade body 111A on the game board on which the variable winning device 111 is arranged, a sufficient movable space is required.

  In general, the blade body 111A has a function of stably guiding a game ball having a predetermined size to the start winning opening 112, so that the size in the length direction of the blade and the size in the thickness direction of the blade are constant. A size larger than the size is required.

  In addition, the wing body 111A has visibility at the time of opening and closing the wing body 111A so as not to impair the interest of the player who is indispensable at the time of playing with a pachinko game machine or the like. It is also necessary to have visual characteristics on the side to enhance the elements. For this reason, the blade body 111 </ b> A needs to be larger than a certain size.

  For this reason, there is a problem that the variable winning device 111 having the blade body 111A that is required to have a configuration of a certain size or more cannot be further reduced in size in the current device.

  Furthermore, in the bullet ball game machine having the variable prize device 111 described in Patent Document 1, the movable space of the blade body on the game board required when the blade body 111A is opened prevents the movement of the blade body 111A. In order to prevent this, there is a design limitation of the nail arrangement in which a nail that obstructs the flow of the game ball cannot be planted at all.

  In particular, the arrangement of the nail that obstructs the flow of the game ball planted at the top of the start winning port 112 has a great influence on the winning rate that changes according to the inflow of the game ball to the start winning port 112. In spite of giving, there is a problem that it is extremely difficult for the game shop side to adjust the winning rate to a desired value because no nail can be planted in the movable space of the blade body.

  Therefore, the present invention has been made to solve the conventional problems described above, and the purpose of the present invention is to provide a variable prize device that is sufficiently equipped with the functions of a conventional ordinary electric accessory, while It is possible to successfully reduce the size to a certain size or less, and to reduce the movable space on the game board when the variable winning device moves, and to reduce the movable space, the nail It is an object of the present invention to provide a ball game machine capable of improving the degree of freedom of arrangement, particularly the design of nail arrangement around a winning opening.

That is, on the condition that a game ball has been won, the prize winning opening is a general winning opening 28 for discharging a predetermined number of winning balls, a start winning opening 32 for starting a variable symbol display on the effect display unit 23, and an effect display unit. When the symbol stop display mode at 23 constitutes a predetermined winning mode, it is configured with a large winning opening 33 that can be switched to a state in which a game ball can be easily received for a predetermined time and a predetermined number of times.

  A shutter 34 that can be switched between a state where it is easy to receive a game ball and a state where it is difficult to receive a game ball is disposed at the entrance of the special winning opening 33. Above the shutter 34, a start winning opening 32 provided with a start winning ball sensor 56 shown in FIG. 7 is provided.

  A ball passage detector 30 is provided at the upper left of the start winning opening 32, and the ball passage detector 30 can detect that a game ball has passed over the ball passage detector 30. Further, immediately above the start winning opening 32, a tilting nail 21 and a tilting nail 22 which will be described later are configured, and a variable winning device 31 that can be switched between a state in which a game ball is easily received and a state in which a game ball is difficult to receive. Is arranged.

  By detecting the passage of the game ball by the ball passage detector 30, it is possible to start the normal symbol variation display on the normal symbol display unit 24. When it is “winning” in the normal symbol display unit 24, the variable winning device 31 that is in a state where it is difficult to receive a game ball in a normal state receives the game ball for a predetermined time (for example, 0.3 seconds). Switch to an easy state.

  The number of passing spheres that have passed through the sphere passing detector 30 can be stored, for example, up to four. For example, based on the stored number of passing spheres, the variation display of the symbols on the normal symbol display unit 24 is performed.

  On the upper right side of the effect display unit 23, for example, four normal symbol memory LEDs 35 for displaying the number of passage memories of the ball passage detector 30 are provided. The number of lighting of the normal symbol storage LED 35 can indicate the number of stored passing spheres detected by the sphere passing detector 30. The number of the normal symbol storage LEDs 35 can be determined according to how many passing balls are stored.

  When a game ball wins the start winning opening 32, a special symbol game is started, and the effect display unit 23 shifts to a variable display state in which the special symbol is variably displayed. In the present embodiment, the special symbol variable display start condition in the effect display unit 23 is based on the condition that a game ball has won the start winning opening 32. In the present embodiment, the variable display start condition for the symbols in the normal symbol display unit 24 is that the game ball has passed through the starting area detected by the ball passage detector 30.

  If the game ball newly wins the start winning slot 32 during the variable display of the special symbol in the special symbol game, the start winning slot until the special symbol in the variable display is derived and displayed on the effect display unit 23. The execution (start) of variable symbol special display based on the winning of a game ball to 32 is put on hold.

  That is, when the predetermined variable display execution condition is satisfied but the predetermined variable display start condition is not satisfied (when the predetermined variable display hold condition is satisfied), the predetermined variable display start condition is satisfied. The execution (start) of variable symbol special display is suspended. If the special symbol is derived and displayed in a state where the execution of the variable display of the special symbol is suspended, the execution of the variable display of the special symbol that is suspended is started.

  It should be noted that the special symbol variable display executed when the special symbol is derived and displayed is once. For example, in the state where execution of variable display of special symbols is held three times, when a special symbol is derived and displayed, one of the variable displays of special symbols held is executed once, and the remaining two symbols are displayed. The batch is held.

  Further, an upper limit is set for the number of times the execution of the special symbol variable display is suspended. For example, the variable symbol variable display is suspended up to four times. Thus, when the variable display of the identification information in the special symbol game is suspended, the number of the suspension is displayed on the four special symbol storage LEDs 36 shown in FIG.

  In the present embodiment, an example in which the variable display of the special symbol is held up to four times as an upper limit, and an example in which the number of stored passages of the ball passage detector 30 is held up as four as an upper limit. Although demonstrated, it is not restricted to this, It can also comprise in another aspect.

  For example, it can be configured to hold the variable display of special symbols or the stored number of passages of the ball passage detector 30 with the upper limit being one (one) or plural (plural). Moreover, it can also comprise so that it may hold without setting an upper limit, or it may be comprised so that the variable display of a special symbol and the passage memory | storage number of the ball passage detector 30 may not be suspended.

  Further, in the description of the embodiment, an example in which the ball passing detector 30 detects the passing ball and the game ball is won at the start winning opening 32 is set as a predetermined variable display start condition is described. However, the present invention is not limited to this, and a predetermined variable display start condition can be set in another manner.

  The effect display unit 23 is provided in a liquid crystal display device provided substantially at the center of the game area 12 and is configured as a display device capable of 7-segment display, and performs variable display of special symbols in a special symbol game. Further, in the effect display unit 23, in addition to the variable display of the special symbol, an effect during the game can be performed by displaying an animation corresponding to the game state.

  The special symbol displayed on the effect display unit 23 is composed of a plurality of symbol columns (for example, three columns), and is configured to be displayed from a plurality of symbols independently for each column. Instead of a plurality of symbol rows, for example, a symbol row can be constituted.

  As the special symbol, a symbol consisting of a numeral, a symbol, or the like can be used. For example, a numeral “0” to “9” and a symbol “−” can be used.

  Further, the case where the special symbol derived and displayed in the effect display unit 23 is in a specific display mode is set to “big hit”, for example. When it is a “hit”, it is possible to play a specific game that is advantageous to the player as compared to the general game.

  As a specific display mode, a display mode based on a normal jackpot symbol, a display mode based on a probable jackpot symbol, and the like can be set. The normal jackpot symbol display mode is, for example, a “normal jackpot” mode in which even numbers such as “8”-“8”-“8” are derived and displayed.

  When the derivation display on the effect display unit 23 becomes the display mode of the normal jackpot symbol, the gaming state is shifted to the jackpot gaming state, and the transferred jackpot gaming state is subjected to, for example, a maximum of 15 round controls. Can do. (The period from when the shutter 34 opens until it closes is called one round)

  As a display mode with a probabilistic jackpot symbol, for example, an odd number such as “7”-“7”-“7”, “9”-“9”-“9” is derived and displayed on the effect display unit 23 “probability "Variation (probability variation) jackpot" mode.

  When the derivation display on the effect display unit 23 becomes a display mode with the probability variation jackpot symbol, the gaming state is shifted to the jackpot gaming state, and after the jackpot gaming state is finished, the transition to the probability variation state as the specific gaming state is performed. To do. The probability variation state is a state in which it is easier to shift to the big hit gaming state than the normal gaming state, and the probability variation state is a state in which the probability of shifting to the big hit gaming state is relatively higher than the normal gaming state.

  As the big hit game state, for example, the shutter 34 that blocks the entrance of the big prize opening 33 is opened to a state where it can easily accept the game ball for a predetermined time and a predetermined number of times, and more game balls than the general game are won. be able to. Thereby, when it becomes a big hit game state, it becomes easy to acquire more prize balls than a normal win state.

  The big winning opening 33 has a detection area (not shown) having the count sensor 53 shown in FIG. 7, and a predetermined number (for example, 10) of game balls passes through the detection area, or a predetermined time (for example, 30 seconds). The shutter 34 is driven to the open state until () elapses.

  In other words, when the shutter 34 is in the open state, if either a predetermined number of game balls won in the big prize opening 33 or a predetermined time elapses, the shutter 34 is closed and the big prize opening is closed. 33 makes it difficult to accept the game ball.

  For example, in the case of the “normal jackpot” mode, when it is possible to shift to a jackpot gaming state of up to 15 rounds, the number of rounds that can shift to the jackpot gaming state every time one round ends Subtracted.

  For this reason, the shutter 34 that has been closed from the open state after the end of one round is driven again to the open state, provided that there are still a number of rounds that allow the transition to the big hit gaming state. The These processes are repeated until the number of rounds becomes zero.

  It should be noted that the special winning opening 33 and the shutter 34 in the present embodiment are provided in a game area in which the game ball can roll, and can be changed between a state where the game ball is easily received and a state where the game ball is difficult to receive. An example of a winning device will be described.

  The normal symbol display unit 24 is displayed as an image in the effect display unit 23. For example, two normal symbols blink alternately. When the flashing of the two normal symbols ends and “winning” is displayed, the variable winning device 31 disposed above the start winning opening 32 is placed in a predetermined manner for a predetermined time. Switch to an easy-to-accept state. As a result, it is possible to make it easier for the game ball to win the start winning opening 32.

  Moreover, the normal symbol display part 24 can also be comprised by two normal symbol display LED, a 7 segment indicator, etc. other than said structure, for example. In the case of a 7-segment display, as a normal symbol to be displayed on the 7-segment display, for example, numbers such as “0”, “1”, “2” ... “7” “8” “9” are displayed in a variable manner. When the stop-displayed number is “3” or “7”, it can be determined as “winning”.

The plug 47 and the plug 48 can also protrude on the surface of the game board 11 so as not to hinder the tilting operation of the tilting nail described later.

  The plug 47 and the plug 48 are formed of a deformable elastic material such as rubber, and have a hollow portion for inserting a tilting nail therein. A plug projection 47a and a plug projection 48a are formed. In the present embodiment, the plug protrusion is formed integrally with the plug, but a ring-shaped member formed as a separate member can be fitted.

  Grooves are formed in the opening 11a and the opening 11b so as to be fitted to the plug projection 47a and the plug projection 48a, and the plug 47 and the plug 48 are fitted so as to be fitted in these grooves. Has been.

  In the present embodiment, the stopper is fixed at the opening of the stopper by fitting the stopper protrusion provided on the stopper and a groove formed in the opening. For example, a plurality of grooves may be formed, or grooves having a geometric shape such as a circle or a square may be formed. Further, as a method of fixing the plug to the game board 11, any method can be used as long as the plug can be fixed to the game board 11 such as various adhesives, other adhesive members, and adhesion by heat.

  The tilting nail 21 and the tilting nail 22 are inserted into hollow portions formed in the plugs 47 and 48, respectively, and are held near the tilting nail central portion 21b and the tilting nail central portion 22b, respectively.

  Since the plug 47 and the plug 48 are formed of an elastic body that can be freely deformed, the movement accompanying the tilting of the tilting nail 21 and the tilting nail 22 can be absorbed by the deformation of the plug 47 and the plug 48. Therefore, the tilting nail 21 and the tilting nail 22 can be freely tilted with the tilting nail central portion 21b and the tilting nail central portion 22b held by the plugs 47 and 48, respectively, as fulcrums.

  In this embodiment, a rubber material is used as the material of the plug 47 and the plug 48. However, the material is not limited to this material, and an elastic material other than rubber has the deformation characteristics required in this embodiment. Any material can be used.

  In addition, in the stopper 47 and the stopper 48, a recess for rotatably storing a spherical body formed in the middle of the tilting nail 21 and the tilting nail 22 can be formed. Furthermore, an annular groove may be formed in the middle of the tilting nail 21 and the tilting nail 22, and an engagement piece that is loosely inserted into the annular groove may be formed in the plug 47 and the plug 48.

  Tilt by the engagement of the spherical body formed in the middle of the tilting nail and the recess formed in the stopper, and by the engagement of the annular groove formed in the middle of the tilting nail and the engagement piece formed in the stopper The nail can be prevented from coming off.

  The plug 47 and the plug 48 prevent the tilting nail 21 and the tilting nail 22 from coming out of the game board 11 due to contact friction between the tilting nail central portion 21b and the tilting nail central portion 22b, and the game ball By functioning as a cushioning material when colliding with the tilting nail 21 and the tilting nail 22, it is possible to prevent transmission of an impact to the drive device 39 described later, and to prevent the tilting nail 21 and the tilting nail 22 from being glazed. Can be prevented.

  As shown in FIGS. 4A and 4B, the driving device 39 includes a tilting nail 21, a variable winning device solenoid 51 for tilting the tilting nail 22, and a variable winning device solenoid 52.

  The variable winning device solenoid 51 and the variable winning device solenoid 52 are attached near the opening 11a and the opening 11b on the back side of the game board 11, respectively.

The variable winning device solenoid 51 includes an arm portion 51a extending from the side surface of the variable winning device solenoid 51, an annular ring portion 51b formed at the tip of the arm portion 51a, and a circuit that will be described later in the variable winning device solenoid 51. And a wiring part 51c for providing a signal.
The variable winning device solenoid 52 includes an arm portion 52a extending from the side of the variable winning device solenoid 51, an annular ring portion 52b formed at the tip of the arm portion 52a, and a circuit described later in the variable winning device solenoid 51. And a wiring part 52c for providing a signal from.

  The arm portion 51a and the arm portion 52a are driven in a manner described later by the variable prize device solenoid 51 and the variable prize device solenoid 52, respectively. By transmitting this driving force to the tilting nail, the tilting nail 21 and the tilting nail 22 are tilted using the tilting nail center portion 21b and the tilting nail center portion 22b as fulcrums and the ring portion 51b and the ring portion 52b as power points. .

  The ring portion 51b and the ring portion 52b are fitted with the tilting nail tip portion 21c and the tilting nail tip portion 22c, respectively. The inner diameter dimensions of the ring portion 51b and the ring portion 52b are respectively the tilting nail tip portion 21c and the tilting nail. It is formed sufficiently larger than the outer diameter of the tip 22c.

  As a result, when the tilting nail 21 and the tilting nail 22 are tilted, the tip of the tilting nail appropriately slides in the ring portion according to the change in the loose fitting state due to the tilting, so that the driving force from the variable prize winning device solenoid is smooth. Can be transmitted to the tilting nail.

  In the present embodiment, the tilting nail 21 and the tilting nail 22 are loosely fitted to the ring portion 51b and the ring portion 52b to constitute a transmission unit for driving force from the variable prize winning device solenoid to the tilting nail. A structure such as a gear or a screw, a mechanical coupling structure, a structure in which the arm portion and the nail tip are directly connected by an elastic material such as rubber, and a spring between the pair of tilting nail 21 and the tilting nail 22 It is also possible to connect the tilting nail 21 and the tilting nail 22 with a wire or the like.

  As shown in FIG. 4A, a cap 21d and a cap 22d are fitted to the tilting nail tip 21c and the tilting nail tip 22c, respectively, in a fixed state. Since the outer diameter dimensions of the cap 21d and the cap 22d are sufficiently larger than the inner diameter dimension of the ring portion, the ring portion does not come off the tilting nail. That is, it has a function of preventing the tilting nail 21 and the tilting nail 22 from coming out of the game board 11.

  Further, when the tilting nail 21 and the tilting nail 22 are tilted, the contact positions of the tilting nail 21 and the tilting nail 22 with the ring part 51b and the ring part 52b are moved, but the ring part is not disturbed at this time. A sufficient distance is provided between 51b and the ring portion 52b and the cap 21d and the cap 22d.

  The tilting nail described in the present embodiment does not need to be a specially processed nail, so that a general nail used in a normal game store can be used as it is.

  Next, the configuration of the variable winning device 31 and the start winning port 32 will be specifically described with reference to FIG. FIG. 5 is a partially enlarged view of the variable winning device 31 and the start winning port 32 arranged on the game board 11. As shown in FIG. 5, the tilting nail 21 and the tilting nail 22 constituting the variable winning device 31 are arranged in parallel in a region immediately above the start winning opening 32.

  The variable winning device 31 described in the present embodiment can be switched between a state in which a game ball is easily received and a state in which it is difficult to receive in a manner described later by tilting the tilting nail 21 and the tilting nail 22.

  The flow direction of the game ball that has flowed down on the game board 11 is changed by colliding with the tilting nail 21 and / or the tilting nail 22 of the variable winning device 31 that is in a state where it is easy or difficult to receive the game ball. In FIG. 5, neither the tilting nail 21 nor the tilting nail 22 is tilted, and the state where none of the tilting nails is tilted will be referred to as a non-tilting state below.

  Further, the example in which the tilting nail 21 and the tilting nail 22 tilt in the horizontal direction has been described. However, the tilting direction of the tilting nail 21 and the tilting nail 22 is not limited to the horizontal direction, and the vertical direction and the diagonal direction. Can also be tilted.

  Furthermore, a tilting nail can be disposed above the start winning opening 32, and the tilting nail can be tilted up and down or obliquely. In addition, the structure which moves a tilting nail up and down is later mentioned using FIG.

[Operation of variable prize device on game board]
Next, the tilting operation of the tilting nail 21 and the tilting nail 22 when the variable winning device 31 is switched to a state where it is easy or difficult to accept the game ball will be specifically described with reference to FIG. FIG. 6A is a partial cross-sectional view showing a state in which the variable winning device 31 is difficult to receive, and FIG. 6B is a partial cross-sectional view showing a state in which the variable winning device 31 is easily received.

  First, the state where it is difficult to accept the variable winning device 31 will be described with reference to FIG. As shown in FIG. 6A, the tilting nail 21 and the tilting nail 22 are moved in the direction of the arrow B1 by the variable winning device solenoid 51 according to a predetermined drive signal supplied from a main CPU 41 described later. The arm portion 52a is driven in the direction of the arrow B2 by the variable winning device solenoid 52, respectively.

  The ring portion 51b formed at the distal end portion of the arm portion 51a is moved in the direction of arrow B1 while gripping the tilted nail distal end portion 21c that is loosely fitted. Then, the tilting nail 21 is driven to tilt in the direction of the arrow A1 with the tilting nail central portion 21b as a fulcrum. When the tilting nail 21 tilts, the stopper 47 is appropriately elastically deformed so as not to hinder the tilting operation of the tilting nail 21.

  Similarly, the ring portion 52b formed at the distal end portion of the arm portion 52a is moved in the direction of the arrow B2 while gripping the tilted nail distal end portion 22c that is gently coupled. Then, the tilting nail 22 is driven to tilt in the direction of the arrow A2 with the tilting nail central portion 22b as a fulcrum.

  Therefore, the tilting nail 21 and the tilting nail 22 receive the game ball from the non-tilting state shown in FIG. 5 because the interval between the tilting nail tip 21c and the tilting nail tip 22c is narrowed by the tilting operation described above. It changes to a difficult state. That is, the variable winning device 31 switches to a state where it is difficult to accept.

  Next, a state where the variable winning device 31 is easily received will be described with reference to FIG. As shown in FIG. 6B, the tilting nail 21 and the tilting nail 22 are moved in the direction of the arrow D1 by the variable winning device solenoid 51 in accordance with a predetermined drive signal supplied from the main CPU 41 described later. The arm portion 52a is driven in the direction of the arrow D2 by the variable winning device solenoid 52, respectively.

  The ring portion 51b formed at the distal end portion of the arm portion 51a moves in the direction of the arrow D1 while gripping the tilting nail distal end portion 21c. Then, the tilting nail 21 is driven to tilt in the direction of the arrow C1 with the tilting nail central portion 21b as a fulcrum. When the tilting nail 21 tilts, the stopper 48 is elastically deformed moderately so as not to hinder the tilting operation of the tilting nail 22.

  Similarly, the ring portion 52b formed at the distal end portion of the arm portion 52a moves in the direction of the arrow D2 while gripping the tilting nail distal end portion 22c. Then, the tilting nail 22 is driven to tilt in the direction of the arrow C2 with the tilting nail central portion 22b as a fulcrum.

  Therefore, the tilting nail 21 and the tilting nail 22 accept the game ball from the non-tilting state shown in FIG. 5 because the interval between the tilting nail tip 21c and the tilting nail tip 22c is widened by the tilting operation described above. It changes to an easy state. That is, the variable winning device 31 is switched to a state where it can be easily received.

  As described above, the variable winning device 31 described in the present embodiment is in a state in which it is difficult to accept the game ball shown in FIG. 6A due to the act of tilting the tilting nail 21 and the tilting nail 22, and FIG. It can be switched to an arbitrary interval with the easy-to-accept state shown in (), and the function of the conventional ordinary electric accessory is sufficiently fulfilled.

  The tilting nail 21 and the tilting nail 22 described in the present embodiment are provided with a variable winning device solenoid 51 and a variable winning device solenoid 52 for driving the tilting nail 21 and the tilting nail 22, respectively. Can be tilted. At that time, in the variable winning device constituted by three or more tilting nails described later, by providing steps in an easy-to-accept state and an un-acceptable state, it is possible to form an easily-acceptable state and an unacceptable state in various ways. it can.

  Further, since only the tilting nail is provided as the variable winning device 31 on the game board 11, the movable space can be sufficiently reduced as compared with the conventional variable winning device configured with a tulip type or the like. It is suppressed. Furthermore, the degree of freedom of the nail arrangement design above the start winning opening 32 is greatly improved.

  In the variable winning device 31 described in the present embodiment, the tilting nail is driven by each solenoid. However, the present invention is not limited to this configuration, and at least one tilting nail is driven by one solenoid. In this case, a mechanical mechanism using a gear, a cam, or the like may be provided.

  Next, when the tilting nail 21 is tilted, a tilting restricting portion 37 is provided to restrict the tilting angle or tilting direction, and a desired tilting angle or tilting direction is set using FIGS. 17 and 18. I will explain. Although the description of the tilting nail 22 is omitted, the tilt angle or the tilting direction can be set by using the same means as in the case of the tilting nail 21 and the following description.

  FIG. 17 is a partial cross-sectional view of the variable winning device 31 when the slit plate 85 is used as the tilt restricting portion 37. As shown in FIG. 17, the variable winning device 31 described with reference to FIG. 4 has a configuration in which a slit plate 85 is interposed between the game board 11 and the arm portion 51a.

  The slit plate 85 is pasted on the back side of the game board 11 so as to cover a part or all of the opening 11 a, and a slit 85 a is formed inside the slit plate 85. The ring portion 51b is loosely fitted inside the slit 85a, that is, the groove width formed in the slit 85a is slightly larger than the outer diameter of the ring portion 51b. . The pillar of the tilting nail 21 can be loosely fitted in the slit 85a, and the ring portion 51b can be separated from the slit plate 85.

  When the tilting nail 21 tilts, the ring portion 51b moves so as to slide along the inner surface of the slit 85a along the groove shape of the slit 85a.

  If the ring part 51b moves more than a certain amount, the ring part 51b cannot move any more by contacting the end of the slit 85a. As a result, the movement range of the ring part 51b is limited by the groove shape of the slit 85a. Will be. In the present embodiment, the tilt angle or the tilt direction is regulated by bringing the ring portion 51b into contact with the slit 85a. However, the ring portion 51b can also be regulated by bringing the slit 85a into contact with the tilting nail 21 directly.

  As described above, by forming the slit 85a in a predetermined slit shape, the moving range or moving direction of the ring portion 51b can be limited, and as a result, the tilting in which the ring portion 51b is loosely fitted. The nail 21 can be tilted so as to form a desired tilt angle or tilt direction.

  The slit 85a may be formed in a curved slit shape, a meandering slit shape, or the like in addition to the linear slit as shown in this embodiment. It can also be formed of at least one or more. Moreover, the attachment position of the slit 85a can be freely changed according to the case where the attachment position of the variable winning device solenoid 51 shown in FIGS. 4 and 17 is changed. Furthermore, without using the slit plate 85, the opening 11a and the opening 11b itself have an inclined surface that expands from the front surface side to the back surface side of the game board 11, and the slit shape as viewed from the back surface side. It can also be formed.

  FIG. 18 is a view from the back side of the game board 11 of the variable winning device 31 using a nut as the tilt restricting portion 37. As shown in FIG. 18, the variable winning device 31 described with reference to FIG. 4 is configured by adding a tilt restricting portion 37, a tilt restricting adjusting portion 38, and a protruding portion 51 d attached to the arm portion 51 a. ing.

  The tilt restricting portion 37 includes a nut 37a and a nut 37b. The tilt regulation adjusting unit 38 has a bolt shape, and is arranged in the vicinity of the variable winning device solenoid 51 on the back side of the game board 11 by the mounting portions provided at both ends of the tilt regulation adjusting unit 38 and in parallel with the arm unit 51a. It is installed.

  Further, the tilt regulation adjusting portion 38 is screwed into the nut 37a and the nut 37b, and the screwing position can be freely changed. The protrusion 51d attached to the arm 51a is formed so as to contact the nut 37a and the nut 37b when the arm 51a is driven by the variable winning device solenoid 51.

  That is, when the arm portion 51a moves left and right in the direction of the arrow A, the projecting portion 51d comes into contact with the nut 37a and the nut 37b on the surface on the side of each projecting portion 51d, thereby restricting the movable range of the arm portion 51a. Will be.

  The material of the protrusion 51d is preferably a material such as a rubber material that absorbs an impact at the time of contact, but any material can be used as long as this embodiment can be realized. The protrusion 51d can be formed in any shape as long as the movement of the arm 51a can be restricted by the nut 37a and the nut 37b coming into contact with each other.

  Further, the tilt regulation adjusting unit 38 can change the screwing positions of the nut 37a and the nut 37b in the arrow B direction and the arrow C direction, respectively. Further, the projecting portion 51d attached to the arm portion 51a has a movable range limited between the screwing positions of the nut 37a and the nut 37b. That is, by adjusting the tilt restricting portion 37 by the tilt restricting adjusting portion 38, the movable range of the arm portion 51a can be freely restricted. As a result, the tilt angle or the tilt direction of the tilting nail 21 can be set as desired. Can be set to a value.

  As a result, the game store side adjusts the tilt regulating portion 37 by the tilt regulation adjusting portion 38, thereby reducing the man-hours required for adjusting the nail using a nail adjusting tool such as a hammer, and the nail of a game store employee or the like. Arbitrary winning percentages can be easily adjusted without the need for specialists for adjustment.

  In the present embodiment, the configuration by the bolt-shaped tilting regulation adjusting unit 38 has been described. However, the mechanical configuration, for example, the mechanical configuration by a combination of gears, racks, motors, etc. Any configuration is possible as long as the tilt restricting portion can be regulated by a configuration with a proper action.

Next, in the variable winning device 31 configuration, another configuration of the tilting nail different from the configuration shown in FIG. 5 will be described with reference to FIGS. 16 (a) and 16 (b).
16 (a) and 16 (b) are enlarged views of the arrangement portion of the variable winning device 31 and the start winning port 32 in which the number of tilting nails and the position where the tilting nails are planted are changed. .

  As shown in FIG. 16 (a), the tilting nail 21 and the tilting nail 22 are paired, and the tilting nail 81 and the tilting nail 82 are paired, and the tilting nails are arranged side by side. Also, as shown in FIG. 16B, when viewed from the front side of the game board 11, three tilting nails, that is, the tilting nail 21, the tilting nail 22, and the tilting nail 83 are positioned at the apex of a substantially triangle. It can also be planted to do. Each of the tilting nails shown in FIGS. 16A and 16B can tilt in the direction of the arrow attached to each tilting nail independently of the tilting of the other tilting nails.

  The variable winning device 31 can be switched between a state where it is easy to receive a game ball and a state where it is difficult to receive it by tilting three or four tilting nails independently. In particular, a step at the time of switching can be provided for ease of acceptance and difficulty of acceptance. In addition, it can also comprise using only the tilting nail 83, without using three nails.

  For example, in the variable winning device 31 shown in FIG. 16A, when the game ball flows down in the direction of the arrow A, four tilting nails, the tilting nail 21, the tilting nail 22, the tilting nail 81, and the tilting nail Since all the 82 are tilted outward, the game ball is most easily received.

  When the game ball flows down in the direction of arrow A, the four tilting nails, the tilting nail 21 and the tilting nail 22, the tilting nail 81 and the tilting nail 82 all tilt inward, so that Easy to accept.

  When only the tilting nail 81 and the tilting nail 82 are tilted outward and the tilting nail 21 and the tilting nail 22 are not tilted, it is harder to accept the game ball than when all the four tilting nails are tilted outward. The game ball can be easily received to some extent.

  Further, when only the tilting nail 81 and the tilting nail 82 are tilted inward and the tilting nail 21 and tilting nail 22 are not tilted, it is easier to accept the game ball than when all four tilting nails are tilted inward. It is possible to make it difficult to accept game balls to some extent.

  In the variable winning device 31 shown in FIG. 16B, when the game ball has flowed down in the direction of the arrow B or C, for example, the tilting nail 83 is tilted upward and the tilting nail 21 is tilted inward. When the tilting nail 22 is tilted outward, it is difficult to receive the game ball to some extent, but it is possible to make the game ball easy to receive to some extent as compared with the case where the tilting nail 83 is tilted downward.

  That is, variations in ease of acceptance or difficulty in acceptance can be provided, and the interest of the player can be further increased.

As shown in FIG. 3, by operating the launch handle 7, the game ball whose launch speed is adjusted according to the amount of rotation of the launch handle 7 is launched into the game area 12. When a game ball launched into the game area 12 collides with the nail 20 or the like and flows down while changing the flow direction and wins a general winning opening 28 or the like, a predetermined number (for example, 10) of prize balls are paid out.

  Also, on the condition that the passing of the game ball is detected by the ball passage detector 30, the normal symbol variation display on the normal symbol display unit 24 is started. And the stop display mode of the normal symbol in the normal symbol display unit 24 is determined by lottery using a random number, and based on this determination, the fluctuation display of the normal symbol is stopped.

  Here, when the stop display mode of the normal symbol in the normal symbol display unit 24 is “winning”, the variable winning device 31 provided above the start winning port 32 is held for a predetermined time (for example, 0.3 seconds). To a state where it is easy to accept.

  Also, on the condition that the game ball has won the start winning opening 32, the special symbol variation display on the effect display unit 23 is started.

  Even in this case, the special symbol stop display mode in the effect display unit 23 is determined by lottery using random numbers, and the special symbol variation display is stopped based on this determination.

  Here, when the special symbol stop display mode in the effect display unit 23 is the “normal jackpot mode” or the “probable variation jackpot mode”, the predetermined winning opening 33 is set for a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10). Open until accepting the winning ball.

  In addition, when the number of rounds is set according to the “usually big win mode”, one round is opened until the big winning opening 33 is received for a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) of winning balls. The process is repeated until the set number of rounds (for example, 15 times) is reached.

  Here, when a game ball enters the opened big prize opening 33, a very large number of game balls are paid out to the player, so that the player has the skill to put as many game balls as possible into the big prize opening 33. Demonstrate.

Thereby, the game board 11 in which the arrangement of the nails 20 is changed can be used for a long time without getting the player bored.

Hereinafter, the processing executed in the pachinko gaming machine 1 is shown in FIGS.
[Main processing]
As shown in FIG. 8, in step S11, RAM access permission, backup return processing, and initial setting processing such as initialization of the work area are executed. Although details will be described later with reference to FIG. 10, in step S <b> 15, special symbol control processing relating to the progress of the special symbol game, the special symbols displayed on the liquid crystal display device 18 and the effect display unit 23 is executed.

  In step S16, a normal winning lottery process is mainly executed. Then, according to the result of the lottery process, determination of a normal symbol stop symbol, a normal symbol variation display pattern, a regular symbol variation display time, and the like is performed.

  As the management process for the normal symbol variation display time, the setting is mainly performed to control the variable winning device 31 to the open state so that the game ball can easily enter the start winning port 32.

  In the main process, after the initial setting process in step S11 is completed, the processes in step S15 and step S16 are repeatedly executed.

[System timer interrupt processing]
Even when the main CPU 41 is executing the main process, the main CPU 41 may interrupt the main process and execute the system timer interrupt process.

  The following system timer interrupt process is executed in response to a clock pulse generated from the reset clock pulse generation circuit 45 every predetermined period (for example, 2 milliseconds).

  This system timer interrupt process will be described with reference to FIG. As shown in FIG. 9, in step S42, the main CPU 41 executes a random number update process so as to increase the count values of the jackpot determination random number counter, the jackpot symbol determination random number counter, and the like by “1”.

  In step S43, the main CPU 41 executes an input detection process for detecting the winning or passing of the game ball to the start winning opening 32 or the like. In the input detection process, the main CPU 41 stores in the predetermined area of the main RAM 43 data indicating that a game ball is to be paid out (prize ball) on condition that the game ball has won a variety of winning holes.

  In step S44, various timer processes, that is, a waiting time timer for synchronizing the main control board 40 and the sub-control board 60, a time for measuring the opening time of the big winning opening 33 that is opened when a big hit occurs. An opening time timer for the big prize opening is executed.

  In step S46, output processing necessary to supply a signal for driving control based on various variables to a driving device such as a solenoid or a motor is executed.

  In step S47, the main CPU 41 supplies various commands to the sub-control board 60 and executes command output processing.

  Specific examples of the various commands include a demo display command, a derived symbol designation command indicating the type of special symbol derived and displayed, a variation pattern designation command indicating a variation display pattern of the special symbol, and the like.

  In the process of step S49, the main CPU 41 transmits a prize ball control command to the payout control circuit 70a, and executes a payout process. Specifically, the main CPU 41 supplies to the payout control circuit 70a a prize ball control command for paying out a predetermined number of prize balls as a result of the game balls winning in various winning holes.

  When the payout process ends, this subroutine ends, returns to the address before the occurrence of the interrupt, and continues to execute the main process.

[Special symbol control processing]
The subroutine executed in step S15 of FIG. 8 will be described using FIG. In FIG. 10, the numerical values drawn on the sides of step S72 to step S80 indicate the control state flags corresponding to those steps, and one step corresponding to the numerical value according to the numerical value of the control state flag. Will be executed and the special symbol game will proceed.

  In step S71, processing for loading the control state flag is executed. In the loading process of the control state flag, the main CPU 41 reads the control state flag.

  In steps S72 to S80, which will be described later, the main CPU 41 determines whether or not to execute various processes in each step based on a value indicating the control state flag, as will be described later.

  The control state flag indicates the game state of the special symbol game, and allows one of the processes from step S72 to step S80 to be executed. Further, the main CPU 41 executes processing in each step at a predetermined timing determined according to a waiting time timer or the like set for each step.

  Before reaching the predetermined timing, the process ends without executing the process in each step, and another subroutine is executed. Of course, the system timer interrupt process can also be executed at a predetermined cycle.

  In step S72, a special symbol memory check process is executed. When the control state flag is a value (00) indicating the special symbol storage check, the main CPU 41 checks the number of reserved pieces. If there is a reserved number, the main CPU 41 determines the jackpot determination, the derived special symbol, and the special symbol variation pattern. Make a decision.

  Further, the main CPU 41 sets a value (01) indicating special symbol variation time management in the control state flag, and sets the variation time corresponding to the variation pattern determined in the current process in the waiting time timer. That is, it is set to execute the process of step S73 after the variation time corresponding to the variation pattern determined this time has elapsed. On the other hand, when there is no pending number, a demonstration display process for displaying a demonstration screen is performed.

  In step S73, a special symbol variation time management process is executed. In the special symbol variation time management process, the main CPU 41 sets the control state flag to a value (01) indicating special symbol variation time management, and when the variation time has elapsed, a value (02 indicating special symbol display time management). ) Is set in the control state flag, and the waiting time after determination (for example, 1 second) is set in the waiting time timer. That is, it is set so that the process of step S74 is executed after the waiting time after determination has elapsed. When the process in step S73 is completed, the process proceeds to step S74.

  In step S74, a special symbol display time management process is executed. When the control state flag is a value (02) indicating the special symbol display time management and the waiting time after the determination has elapsed, the main CPU 41 determines whether or not it is a big hit. When the main CPU 41 determines that it is a big hit, it sets a value (03) indicating the big hit start interval management in the control state flag, and sets a time (for example, 10 seconds) corresponding to the big hit start interval in the waiting time timer. To do.

  That is, after the time corresponding to the jackpot start interval elapses, the setting of step S75 is performed.

  On the other hand, if the main CPU 41 determines that it is not a big hit, it sets a value (08) indicating the end of the special symbol game to the control state flag. That is, it sets so that the process of step S80 may be performed. When the process in step S74 is completed, the process proceeds to step S75.

  In step S75, a jackpot start interval management process is executed. In this process, the main CPU 41 has a value (03) indicating that the control status flag indicates the jackpot start interval management, and when the time corresponding to the jackpot start interval has elapsed, in order to open the jackpot 33, Based on the data read from the main ROM 42, the variables positioned in the main RAM 43 are updated.

  The main CPU 41 sets a value (04) indicating that the special winning opening is being opened to the control state flag, and sets an open upper limit time (for example, 30 seconds) to the special winning opening time timer. That is, it sets so that the process of step S77 may be performed.

  In addition, the main CPU 41 sets data indicating a winning prize opening command in a predetermined area of the main RAM 43. The data indicating the opening command of the big prize opening stored in this way is released from the main CPU 41 of the main control board 40 to the sub CPU 61 of the sub control board 60 by the command output process of step S47 of FIG. Supplied as a command.

  This makes it possible to recognize that the special winning opening 33 is in the open state on the sub-control board 60. If this process ends, the process moves to a step S76.

  In step S76, a waiting time management process before reopening of the special winning opening is executed. In this process, the main CPU 41 determines that the control status flag is a value (06) indicating the reopening waiting time management of the big winning opening, and when the time corresponding to the interval between rounds has elapsed, the number of opening of the big winning opening. The counter is updated so that the counter is incremented by “1”.

  The main CPU 41 sets a value (04) indicating that the special winning opening is being opened in the control state flag. Further, the main CPU 41 sets the opening upper limit time (for example, 30 seconds) in the opening time timer of the big prize opening. That is, it sets so that the process of step S77 may be performed.

  Further, the main CPU 41 sets data indicating a winning prize opening command in a predetermined area of the main RAM 43.

  The data indicating the opening command for the big prize opening stored in this way is released from the main CPU 41 of the main control board 40 to the sub CPU 61 of the sub control board 60 by the process of step S47 in FIG. Supplied as a command. This makes it possible to recognize that the special winning opening 33 is in the open state on the sub-control board 60.

  In step S77, processing for opening the special winning opening is executed. In this process, when the control status flag is a value (04) indicating that the big prize opening is open, the main CPU 41 says that the big prize mouth prize counter is a predetermined number (for example, “10” or more). It is determined whether or not any of the conditions or the condition that the upper opening limit time has elapsed (the opening time timer of the big prize opening is “0”) is satisfied (a predetermined closing condition is satisfied). .

  When the main CPU 41 determines that such a condition is satisfied, the main CPU 41 updates a variable positioned in the main RAM 43 in order to close the special winning opening 33.

  Then, the main CPU 41 sets a value (05) indicating monitoring of the winning ball residual ball in the control state flag. The main CPU 41 sets data indicating an interval command between rounds in a predetermined area of the main RAM 43.

  The data indicating the interval command between rounds stored in this way is supplied as the interval command between rounds from the main CPU 41 of the main control board 40 to the sub CPU 61 of the sub control board 60 by the process of step S47 in FIG. . This makes it possible to recognize that the special winning opening 33 is closed on the sub-control board 60.

  The main CPU 41 sets the winning ball residual ball monitoring time (for example, 1 second) in the waiting time timer. That is, it is set so that the process of step S78 is executed after the winning ball residual ball monitoring time has elapsed. Note that the main CPU 41 does not execute the above-described processing when none of the conditions is satisfied.

  In step S78, a special winning opening residual ball monitoring process is executed. In this process, the main CPU 41 indicates that the control state flag is a value (05) indicating monitoring of the winning ball remaining ball, and if the winning ball remaining ball monitoring time has elapsed, It is determined whether or not the condition that the number of times of opening the big winning opening is equal to or greater than the maximum value (specifically, 15 rounds in the normal jackpot gaming state) is satisfied.

  When the main CPU 41 determines that the condition is satisfied, the main CPU 41 sets a value (07) indicating the jackpot end interval in the control state flag, and sets a time corresponding to the jackpot end interval in the waiting time timer. That is, after the time corresponding to the jackpot end interval has elapsed, the process of step S79 is executed.

  When the main CPU 41 determines that none of the above conditions is satisfied, the main CPU 41 sets a value (06) indicating management of the reopening waiting time for the special winning opening in the control state flag.

  Further, the main CPU 41 sets a time corresponding to the interval between rounds in the waiting time timer. That is, after the time corresponding to the interval between rounds has elapsed, the setting of step S76 is performed. If this process ends, the process moves to a step S79.

  As described above, the main CPU 41 that executes step S75 to step S78 performs round control for controlling the big winning opening 33 and the shutter 34 to the closed state after the opened in the normal jackpot gaming state to be transferred, Control is performed so as to be executable up to a predetermined upper limit number of rounds. Further, in the probability variation big hit gaming state to be transferred, the round control is performed for one round.

  The processing in the main CPU 41 that executes the processing as described above corresponds to an example of processing in the big hit gaming state control means.

  In step S79, a big hit end interval process is executed. In this process, the main CPU 41 sets a value (08) indicating the end of the special symbol game when the control state flag is a value (07) indicating the jackpot end interval and the time corresponding to the jackpot end interval has elapsed. Set to flag. That is, it sets so that the process of step S80 may be performed. Then, the main CPU 41 performs control to shift to the probability variation state when the jackpot symbol is the probability jackpot symbol, and performs control to shift to the normal jackpot gaming state when the jackpot symbol is the normal jackpot symbol. It will be.

  In step S80, a special symbol game end process is executed. In this process, when the control state flag is a value (08) indicating the end of the special symbol game, the main CPU 41 stores and updates the data indicating the number of holdings (starting storage information) to be decreased by “1”.

  Then, the main CPU 41 updates the special symbol storage area and sets a value (00) indicating a special symbol storage check in order to perform the next fluctuation display. That is, it sets so that the process of step S72 may be performed. When this process is finished, this subroutine is finished.

  The main CPU 41 sets the control state flags in the order of (00), (01), (02), and (03) when the result of the big hit determination is a big hit in a gaming state that is not a big hit gaming state.

  Thereby, the process of step S72, step S73, step S74, and step S75 shown in FIG. 10 can be executed at a predetermined timing, and control to the big hit gaming state can be executed.

  Furthermore, when the control to the big hit gaming state is executed, the main CPU 41 sets the control state flags in the order of (04), (05), and (06), so that step S77 shown in FIG. The process of step S78 and step S76 can be executed at a predetermined timing to execute a specific game.

  In the case where the specific game is being executed and the end condition of the big hit game state (specific game end condition) is satisfied, the control state flags are set to (04), (05), (07), (08). By setting in this order, the processing from step S77 to step S80 shown in FIG. 10 can be executed at a predetermined timing to end the big hit gaming state.

  In addition, the specific game end condition ends the big hit game state on condition that the maximum number of continuation of the big hit round (upper limit round number, for example, 15 rounds in the normal big hit game state) has ended.

[Normal symbol control processing]
Next, the normal symbol control process in step S16 shown in FIG. 17 will be described with reference to FIG. FIG. 11 is a flowchart showing the processing procedure of the normal symbol control processing according to the embodiment. In addition, a state where a game ball is easily received is referred to as an open state, and a state where it is difficult to receive a game ball is referred to as a closed state.

  In step S30-1, the main CPU 41 executes processing for loading the normal symbol control state flag. The normal symbol control state flag is a flag indicating a game state in the normal symbol game, and the main CPU 41 executes each process in step S30-2 or step S30-6 based on the normal symbol control state flag. It is determined whether or not to do so.

  In step S30-2, the main CPU 41 performs a normal symbol storage check process (see FIG. 12), which will be described later in detail. Here, a normal winning lottery process is mainly performed. Then, according to the result of the lottery process, determination of a normal symbol stop symbol, a normal symbol variation display pattern, a regular symbol variation display time, and the like is performed.

  In step S30-3, the main CPU 41 sets the normal symbol control state flag to a value (01) indicating normal symbol variation time management, and the value of the normal symbol wait time timer in which the normal symbol variation display time is set is “0”. ”, The normal symbol variation display is terminated, a value (02) indicating normal symbol display time management is set in the normal symbol control state flag, and a waiting time after determination (for example, 0.5 Second) is set to the normal symbol waiting time timer.

  In step S30-4, the main CPU 41 performs a normal symbol display time management process (see FIG. 13), which will be described later in detail. Here, the setting for making the start winning opening 32 open is mainly performed.

  In step S30-5, the main CPU 41 executes a normal power combination release process (FIG. 14), which will be described later in detail. Here, mainly, a process of opening the start winning opening 32 is executed.

[Normal symbol memory check processing]
Next, the normal symbol memory check process in step S30-2 will be described with reference to FIG. FIG. 12 is a flowchart showing the processing procedure of the normal symbol storage check process according to the embodiment.

  In step S30-2-1, the main CPU 41 confirms whether or not the normal symbol control state flag is a value (00) indicating a normal symbol storage check. When the normal symbol control state flag is a value (00) indicating the normal symbol storage check, the main CPU 41 proceeds to the process of step S30-2-2, and the normal symbol control state flag performs the normal symbol storage check. If it is not the indicated value (00), the normal symbol storage check process is terminated.

  In step S30-2-2, the main CPU 41 confirms whether or not the value of the passing memory counter is “0” (that is, whether or not the number of reserved memories is “0”). If the value of the passage memory counter is “0”, the process proceeds to step S30-2-3. On the other hand, if the value of the passage memory counter is not “0”, the process proceeds to step S30-2-4. Move on to processing.

  In step S30-20-3, the main CPU 41 generates and sets a normal symbol demo effect command for instructing the normal symbol display unit 24 to execute the normal symbol demo effect display. The normal symbol demonstration effect command is generated when the normal symbol change display operation is not performed in the normal symbol display unit 24 and there is no reserved memory. In addition, this command is output to a sub-control board 60 (not shown) at a predetermined transmission timing.

  In step S30-2-4, the main CPU 41 as the first lottery means performs a normal winning lottery based on the random number for normal winning lottery included in the reserved storage.

  In the normal winning lottery, the normal lottery table to be referred to is different depending on whether the gaming state is the normal gaming state or the gaming state is the open state increasing gaming state (probability variation state or short-time state). Yes. In other words, the normal lottery table referenced in the normal gaming state has a larger number of lottery values for the normal per lottery table referred to in the open state increasing gaming state, which makes it easier to win a normal win. Yes.

  In the present embodiment, in the open state increased game state, the normal winning lottery table having a lot of normal winning lottery values is referred to as described above, so that it is easy to win a normal winning lot. However, the present invention is not limited to this. The winning probability in the open state increased game state and the normal game state may be set to the same rate, and the fluctuation display time of the normal symbol in the open state increased game state may be shortened compared to that in the normal game state.

  In step S30-2-5, the main CPU 41 determines the stop symbol of the normal symbol in the normal symbol display unit 24 based on the lottery result performed in step S30-2-4, and determines the normal symbol based on the determination. Generate and set a stop symbol command.

  For example, when the lottery result performed in step S30-2-4 is a normal winning, a stop symbol indicating a normal winning is determined, and a normal stop symbol command is generated and set based on the determination. . On the other hand, when the lottery result performed in step S30-2-4 is not normal, a stop symbol indicating a loss is determined, and a normal stop symbol command is generated and set based on the determination.

  In step S30-2-6, the main CPU 41 confirms whether or not the gaming state is an open state increasing gaming state (probability variation state or short time state). Then, when the gaming state is the open state increasing gaming state (probability variation state or short time state), the main CPU 41 proceeds to the processing of step S30-2-8, while the gaming state is the open state increasing gaming state ( If it is not the probability variation state or the short time state), the process proceeds to step S30-2-7.

  In step S30-2-7, the main CPU 41 determines a normal symbol variation display pattern by random lottery, and generates and sets a normal symbol variation display pattern command based on the determination. In step S30-2-7, the waiting time (30 seconds) is set in the normal symbol waiting time timer.

  Here, the normal symbol variation display is performed based on the determined normal symbol variation display pattern during the time set in the normal symbol waiting time timer. When the value of the normal symbol waiting time timer becomes “0”, the normal symbol that is variably displayed stops in a state where the symbol based on the normal stop symbol command is displayed.

  In step S30-2-8, the main CPU 41 determines a normal symbol variation display pattern by random lottery, and generates and sets a normal symbol variation display pattern command based on the determination. In step S30-2-8, the waiting time (6 seconds) is set in the normal symbol waiting time timer.

  In step S30-2-9, the main CPU 41 sets a value (01) indicating normal symbol variation time management in the normal symbol control state flag.

  In step S30-2-10, the main CPU 41 erases the random number value and the like used in the current normal symbol storage check process from a predetermined storage area.

[Normal symbol display time management process]
Next, the normal symbol display time management process of step S30-4 shown in FIG. 11 will be described with reference to FIG. FIG. 13 is a flowchart showing the processing procedure of the normal symbol display time management processing according to the embodiment.

  In step S30-4-1, the main CPU 41 confirms whether or not the normal symbol control state flag is a value (02) indicating normal symbol display time management. Further, the main CPU 41 proceeds to the processing of step S30-4-2 if the value is the normal symbol display time management value (02), and if it is not the normal symbol display time management value (02), The normal symbol display time management process is terminated.

  In step S30-4-2, the main CPU 41 checks whether or not the value of the normal symbol waiting time timer is “0”. Further, when the value of the normal symbol waiting time timer is “0”, the main CPU 41 ends the normal symbol display time management process.

  In step S30-4-3, the main CPU 41 confirms whether or not the normal winning is won as a result of the normal winning lottery performed in step S30-2-4. The main CPU 41 proceeds to the process of step S30-4-5 when winning in the normal win, and moves to the process of step S30-4-4 in the case of not winning in the normal win.

  In step S30-4-4, the main CPU 41 sets a value (04) indicating the end of the normal symbol game in the normal symbol control state flag, and ends the normal symbol display time management process.

  In step S30-4-5, the main CPU 41 confirms whether or not the gaming state is an open state increasing gaming state (probability variation state or short time state). When the gaming state is the open state increasing gaming state (probability variation state or short time state), the main CPU 41 proceeds to the processing of step S30-4-6, while the gaming state is the opening state increasing gaming state ( If it is not the probability variation state or the short time state), the process proceeds to step S30-4-7.

  In step S30-4-6, the main CPU 41 sets “2” in the value of the variable winning remaining opening number counter and sets the opening time (2.2 seconds) in the variable winning device opening time flag. As a result, the tilting nail 21 and the tilting nail 22 provided in the variable prize winning device 31 are tilted in the variable prize winning device releasing process described later, so that the variable prize winning device 31 is opened twice for 2.2 seconds. Switch.

  In step S30-4-7, the main CPU 41 sets “1” to the value of the variable winning remaining opening number counter, and sets the opening time (0.2 seconds) to the variable winning device opening time flag. Thereby, the tilting nail 21 and the tilting nail 22 provided in the variable winning device 31 are tilted by the variable winning device opening process described later, and the variable winning device 31 is switched once to the open state for 0.2 seconds. .

  In step S30-4-8, the main CPU 41 sets an opening waiting time (6.7 seconds) in the variable winning device opening waiting time timer.

  In step S30-4-9, the main CPU 41 sets a value (03) indicating the variable winning device open state in the normal symbol control state flag, and ends the normal symbol display time management process.

[Variable winning device opening process]
Next, the variable winning device opening process of S30-5 shown in FIG. 11 will be described with reference to FIG. FIG. 14 is a flowchart of the processing procedure of the variable winning device release processing according to the present embodiment.

  In step S30-5-1, the main CPU 41 confirms whether the normal symbol control state flag is a value (03) indicating that the variable winning device is released. On the other hand, when the normal symbol control state flag is a value (03) indicating that the variable winning device is released, the main CPU 41 proceeds to the process of step S30-5-2, while the normal symbol control state flag is the variable winning device. If it is not the value (03) indicating opening, the variable winning device opening process is terminated.

  In step S30-5-2, the main CPU 41 confirms whether or not the open state waiting time is set in the variable winning device opening waiting time timer. If the release waiting time is set as a result of the confirmation, the process proceeds to step S30-5-3 (FIG. 15). If the opening waiting time is not set, step S30-5-5 is executed. The process proceeds to 6.

  As shown in FIG. 15, in step S30-5-3, when the value of the variable winning device release waiting time timer is “0”, the main CPU 41 proceeds to the process of step S30-5-4 to change the value. If the value of the winning device release waiting time timer is not “0”, the variable winning device release processing is terminated.

  In step S30-5-4, the main CPU 41 sets the opening time set in the variable winning device opening time flag in the variable winning device opening time timer.

  In step S30-5-5, the main CPU 41 tilts the tilting nail 21 and the tilting nail 22 to switch the variable winning device 31 to the open state, so that the game ball easily flows into the start winning opening 32.

  As shown in FIG. 14, in step S30-5-6, the main CPU 41 confirms the value of the variable winning device winning counter. Then, when the value of the variable winning device winning counter is 4 or more, the main CPU 41 proceeds to Step S30-5-8 to close the variable winning device 31 and the value of the variable winning device winning counter is set. When it is 4 or less, the process proceeds to step S30-5-7.

  In step S30-5-7, the main CPU 41 confirms whether or not the value of the variable winning device open state time timer is “0”. When the value of the variable winning device opening time timer is “0”, the main CPU 41 proceeds to the process of step S30-5-8 for closing the variable winning device 31.

  On the other hand, if the value of the variable winning device opening time timer is not “0”, the variable winning device opening process is terminated. In the normal gaming state, when the value of the variable winning device opening time timer becomes “0”, 0.2 seconds have elapsed since the tilting nail 21 and the tilting nail 22 are tilted so as to be in the open state. Means that

  On the other hand, when the value of the variable winning device opening time timer becomes “0” in the open state increasing gaming state (probability variation state or short time state), the tilting nail 21 and the tilting nail 22 are closed. It means that 2.2 seconds have passed since tilting.

  In step S30-5-8, the main CPU 41 tilts the tilting nail 21 and the tilting nail 22 so as to be in the closed state, and switches the variable winning device 31 to the closed state. Further, the main CPU 41 sets “0” to the value of the variable winning device winning counter, and subtracts “1” from the value of the variable winning device remaining opening number counter.

  In step S30-5-9, it is confirmed whether or not the value of the variable winning device remaining opening number counter is “0”. As a result of the confirmation, when the value of the variable winning device remaining opening number counter is “0”, the main CPU 41 proceeds to the process of step S30-5-11. On the other hand, if the value of the variable winning device remaining opening number counter is not “0”, the process proceeds to step S30-5-10 to make the variable winning device 31 open again.

  In step S30-5-10, the main CPU 41 sets an opening waiting time (6.7 seconds) in the variable winning device opening waiting time timer.

  In step S30-5-11, the main CPU 41 sets a value (04) indicating the end of the normal symbol game in the normal symbol control state flag.

  In step S30-6 shown in FIG. 11, when the normal symbol control state flag is a value (04) indicating the end of the normal symbol game, the main CPU 41 subtracts “1” from the value of the passing memory counter. The main CPU 41 shifts the data stored in the normal symbol storage areas (“1” to “4”) to the normal symbol storage areas (“0” to “3”), respectively, and also stores the normal symbol storage. A value (00) indicating the check process is set in the normal symbol control state flag.

  The normal symbol storage area is a reserved storage area that is allocated to the main RAM 43 and is extracted on condition that the game ball has passed the ball passage detector 30. The random numbers for normal lottery and the like stored in the normal symbol storage area (“1” to “4”) correspond to the reserved storage displayed on the normal symbol storage LED 35, and the normal symbol storage area “0”. The random number value for the normal winning lottery stored in is used for the normal winning lottery in step S30-2-4.
