Description

  The present invention relates to a ball game machine such as a pachinko machine, and more particularly to a ball ball game machine that can prevent an illegal act of illegally trying to win a prize by holding an open prize opening / closing member.

  Generally, as a ball game machine, for example, a pachinko machine, after a game ball staying in a ball tray is launched into the game area of the game board according to the operation of the launching handle, it is applied to obstacle nails, windmills, etc. in the game area It is known that it is configured to flow down the board surface while being guided to enter various winning holes, or to flow into the outlets at the lower part of the game area without entering (see Patent Document 1).

  With this type of pachinko machine, when a player enters a general winning opening, a corresponding number of game balls are paid out. And a predetermined number of game balls are paid out. Depending on the production pattern selected based on this lottery result, for example, using a liquid crystal display screen provided in the center part of the game board, visual expression through various illumination devices, auditory expression through a speaker, etc. Various productions are performed. When a win (hereinafter also referred to as a “big hit”) occurs (that is, when a lottery in a special game state is won), a big winning opening called an attacker is opened, and a large number of games corresponding to the pitch It becomes a special game state advantageous to the player to which the ball is paid out.

  On the other hand, the following pachinko machines are also known (see Patent Document 2). The pachinko machine has a center role with left and right blades that open and close at the center of the game area, a start port on the lower left of the center role, and a big hit start port on the right side. Furthermore, it has a big prize opening in the lower center. In the pachinko machine, the blades open and close a certain number of times each time the start opening is won during the game. At this time, when the launched game ball is picked up by the blades in a timely manner and enters the center role, the game ball once rolls on the upper plate to the rear of the game board and falls. The game ball falls while avoiding the obstacle device or collides with the obstacle device, changes the course, falls, and enters either the outlet or the V zone.

  A rotary body that rotates slowly in one direction is disposed at the entrance to the V zone, and the rotary body normally includes a V zone groove and a special V zone groove in a point-symmetric state. When a ball enters the normal V-zone groove, the blade is opened and closed, for example, 18 times by turning on the continuation switch. When a predetermined number of game balls are won during that time, the blade opening and closing operation ends. At this time, when the game ball wins the normal V zone groove, the opening / closing operation of the blades and the number of winning balls are reset by the action of the continuation switch, and the big hitting operation is started again. Then, when the count number of the blade opening / closing operation started by winning the normal V zone groove reaches a predetermined number, it becomes the final round, and at that time the special V zone groove faces upward due to the rotation of the rotating body. When winning in the special V zone groove, the jackpot start port becomes effective. In this state, when a winning is made at the jackpot starting opening, the opening operation is repeated until the large winning opening below the center accessory completes a predetermined time or a predetermined number of winnings.

The played game ball is introduced into the through hole 53a of the drum 53 along the arrow L1 and wins the V zone winning opening 47 with a high probability. Further, as shown in FIG. 3B, when the guide path 51 is rotated at an angle deviated from directly above the drum 53, the game ball is not introduced into the through hole 53a of the drum 53, In many cases, the player falls to the outside and wins a game ball winning opening 46.

  Here, a forced closing mechanism that forcibly closes the open blade member 37 will be described with reference to FIGS. 1, 2, and 4. 4 is an enlarged perspective view showing the forced closing mechanism in detail, (a) shows the state of the forced closing mechanism when the blade member 37 is opened, and (b) shows the blade member 37 by the forced closing mechanism. The closed state is shown. The forced closing mechanism is composed of a cam member 71 and a rod member 73 which will be described later.

  As shown in FIG. 4 (a), in the game area 7a of the transparent glass 6, the game area 7a is rotated by a well-known support mechanism (not shown) in the front-rear direction of the game area 7a (that is, the front-back direction in FIG. 1). A shaft 38 is movably supported, and the shaft 38 is fixed to the tip with the base of the blade member 37 penetrating the hole 37a, and the rear end of the interlocking arm 74 is attached to the rear end. It is fixed. A solenoid 75 is disposed at a position corresponding to the distal end portion of the interlocking arm 74, and a plunger 75 a of the solenoid 75 is rotatably connected to the distal end portion of the interlocking arm 74 via a pin 76. The blade member 37 and the interlocking arm 74 are rotated to a position where the blade member 37 opens the special prize opening 30 in the protruding state (advance position) of the plunger 75a shown in FIG. When the plunger 75a is in the retracted state (retracted position) shown in FIG. 5B, the angle with respect to the shaft 38 is fixed so that the blade member 37 is rotated to the position where the special winning opening 30 is closed. The solenoid 75 in the present embodiment is configured to cause the plunger 75a to protrude by an urging force of an internal compression spring (not shown), while attracting the plunger 75a and retreating to the inner side by excitation. ing.

  A cam member (closing member, actuated member) 71 is fixed to the central portion of the shaft 38. Further, below the shaft 38, two support members 72 are provided for moving and guiding a long rod member (moving member) 73 so as to be slidable in the front-rear direction of the game area 7a. Each of the support members 72 has a guide hole 72a. The guide hole 72a is positioned and fixed so that the rod member 73 can be slidably guided in the front-rear direction of the game area 7a. The rod member 73 is configured to be close to the inner surface of the transparent glass 6 when the blade member 37 is opened while being supported by the support member 72 so as to be movable in the depth direction of the game area 7a. The transparent glass 6 moves in the same direction in conjunction with a slight movement when pressed to the game board 7a side. The rod member 73 is closer to the inner surface side of the transparent glass 6 than any other part of the center accessory 29 and any game parts in the game area 7a, and the transparent glass 6 is illegally pushed. In this case, the one end 73a is pressed first.

  The cam member 71 is configured to close the open blade member 37 in conjunction with the movement of the rod member 73. That is, the cam member 71 receives force from the other end portion 73b of the rod member 73 that is pushed by the one end portion 73a when the transparent glass 6 slightly moves toward the game board 7 side, and closes the blade member 37 (FIG. 4). (b) is operated so as to rotate in the direction of arrow C), and the pressing force in one direction (the direction of arrow A in FIG. 4B) of the other end 73b of the rod member 73 is applied to the blade member 37. It is converted into a rotational force in the closing direction (the direction of arrow C in FIG. 4B).

  Specifically, the cam member 71 is formed in an oval shape as a whole, one end side thereof is fixed to the shaft 38, and the other end side is a position where the cam surface 71 a can contact the other end portion 73 b of the rod member 73. As shown in FIG. The cam surface 71a has a shape that is gradually cut away upward from the other end 73b at the open position of the blade member 37 in FIG. 4A. In the state shown in FIG. When the rod member 73 is pushed and moved in the same direction (the direction of arrow A in FIG. 4B), the rod member 73 whose relative position with respect to the shaft 38 is determined by the support member 72 is the cam surface 71a of the cam member 71. Since the cam member 71 slides the cam surface 71a toward the other end 73b, the cam member 71 moves in the backward direction while being in contact with the shaft, and rotates clockwise about the shaft 38 (the direction of arrow B in FIG. 4B). ).

  At this time, the solenoid 75 holds the blade member 37 in the open position with the plunger 75a protruding from the solenoid body, but rotates together with the cam member 71 in the same direction (direction of arrow D in FIG. 4B). The moving interlocking arm 74 is pushed against the urging force of a spring (not shown) inside the solenoid body, and retracts to the state shown in FIG. 4B to allow the cam member 71 to rotate. . As a result, the blade member 37 is rotated clockwise (in the direction of arrow C in FIG. 4B) to reach the closed position.

  Next, the control system of the pachinko machine 1 in the present embodiment will be described with reference to FIG.

The discharge control device 61 controls to discharge a game ball by driving a discharge unit (not shown) based on prize ball control information input from the game control device 60. That is, when the game control device 60 detects a winning by the first winning port sensor 65, the second winning port sensor 66, and the winning port sensors A1 to A3 provided in each winning port of the game area 7a, The information on the number of winning balls set in advance corresponding to the winning value is transmitted to the discharge control device 61. Then, the discharge control device 61 receives the prize ball number information and performs prize ball discharge control according to the received information.

  On the other hand, the above-described lottery means stores in ROM 62b the number of rounds for continuing to open and close the specific winning port 30 associated with the jackpot determination upon reception of the V winning detection signal from the continuation sensor 67 corresponding to the V zone winning port 47. Determined by lottery based on production random number. There are three rounds of 3, 7, and 15 rounds. When the V winning detection signal is received at the end of each round of 3 and 7, the next round number is drawn again. The jackpot game will continue for up to 15 rounds. Then, when the jackpot lottery is determined by the lottery means, various light emission / display effects such as the effect lighting device 9 and the symbol display device 43 by the game control device 60 are performed in a timely manner. In the present embodiment, during the jackpot game, one game ball is won at the specific winning opening 30 or the specific winning opening 30 is opened and closed 15 times to complete one round.

  Next, the operation of the pachinko machine 1 will be described. That is, when a player seated facing the pachinko machine 1 holds the launch handle 17 and rotates it to an appropriate angle, the launch control device 70 controls the ball launch device 16 based on the rotation angle. Thereby, the ball is continuously fired toward the game area 7a at predetermined time intervals by the operation of the ball launching device 72. Then, a large number of game balls that are launched into the game area 7a and rolling and falling win the timely winning holes 25, 27, etc., or roll and fall without being involved in these, so that the lowermost of the game area 7a It is discharged from the out port 22 to the back side of the game board 7.

  During such a game, in the game ball guiding unit 26, in a normal state where the movable member 35 is not swung, the movable member 35 is accommodated in the guiding member 33, and the side surface of the movable member 35 is Is not extended from the game ball guide path 36. At this time, when the game ball launched into the game area 7 a falls on the upper portion of the guide member 33, the game ball rolls along the game ball guide path 36 and reaches the end of the game ball guide path 36. After reaching, it falls down.

  Further, in a normal state in which the movable member 35 is not swung, the game ball launched into the game area 7 a is closer to the center than the end of the game ball guiding path 36, that is, the end and the winning hole 31. , 32, it falls downward. In this case, the game ball appropriately comes into contact with the obstacle nail disposed in the game area 7a, and in many cases, the game ball falls as it is.

  On the other hand, when the movable member 35 is in a special state where it is swung, the side surface of the movable member 35 is extended from the game ball guiding path 36 of the guiding member 33. At this time, when the game ball falls on the upper portion of the guide member 33, the game ball rolls along the guide path 36, continues to move to the side surface of the movable member 35, and falls toward the second winning opening 32. .

  When the game ball wins the first winning opening 31, the blade member 37 of the center accessory 29 performs one opening / closing operation (about 0.5 seconds) by the large winning opening solenoid 39. When the game ball wins the second winning opening 32, the blade member 37 of the center accessory 29 performs two opening / closing operations (about 0.5 seconds) by the large winning opening solenoid 39. In this way, when the blade member 37 is in the open state, some of the game balls launched into the game area 7 a are introduced from the specific winning opening 30 into the center accessory 29.

  Then, the game ball introduced into the center accessory 29 falls while coming into contact with the V zone guiding device 45 and the like, and goes to the game ball winning port 46 or the V zone winning port 47. At this time, the upper portion 45a of the V zone guide device 45 is periodically rotated at a predetermined speed in the direction of the arrow E (about one reciprocation about one reciprocation) by the motor 52 being driven and controlled by a command from the game control device 60. 10 seconds). When the game control device 60 determines that the game ball introduced into the center accessory 29 has passed the route indicated by the arrow L1 and won the V zone winning opening 47, an effect corresponding to this, for example, The display of the character “V zone winning” on the symbol display device 43 is controlled.

  When the game ball wins the V zone winning slot 47, the type of jackpot, that is, the number of rounds for opening and closing the specific winning slot 30 in the jackpot game is determined by the lottery means in the game control device 60. When the number of rounds is determined, the big win game in which the blade member 37 is actuated by driving the special prize opening solenoid 39 and the specific prize opening 30 is opened and closed is started. Here, when the game ball launched into the game area 7a is introduced into the center accessory 29 from the specific game port 30 when the specific game port 30 is opened, it passes through the route such as the guide path 51 described above. The game ball winning slot 46 or the V zone winning slot 47 is won.

  In addition, for example, when the initial number of rounds is determined to be 3 in the jackpot game, if the V-zone winning slot 47 wins during the final round of the third time, the determination of the number of rounds is made again by lottery means. It is then determined whether the jackpot ends or further jackpots continue. When continuation is decided, the number of rounds is extended within a range where the number of rounds does not exceed 15 (for example, 7 is increased to 10 in total), and that is notified to the player. An effect is performed on the effect lighting device 9 and the symbol display device 43, etc. in a timely manner under the control of the game control device 60, so that these contents are executed as an effect display appealing to the player's vision. .

  When the player performs the game as described above, the game balls are appropriately awarded to the winning ports 25 and 27, the first winning port 31, the second winning port 32, the gaming ball winning port 46, and the V zone winning port 47. Then, a large amount of game balls corresponding to each winning value are paid out from the ball supply port 13 to the upper plate 12.

  During the above-described game, for example, for the purpose of illegally obtaining a ball, the timing at which the blade member 37 opens and closes once and twice by winning the first winning port 31 and the second winning port 32. Then, the portion of the transparent glass 6 facing the center role 29 is strongly pressed, the center role 29 is bent, the blade member 37 is held in the open position, and an attempt is made to illegally enter the ball from the special winning opening 30. However, fraud is reliably prevented as follows. That is, when the transparent glass 6 is pushed into the game area 7a, the moving transparent glass 6 pushes the one end 73a of the rod member 73 first on its inner surface. As a result, the other end portion 73b advances toward the cam surface 71a of the cam member 71 located at the position shown in FIG. 4A, so that the cam member 71 gradually bites into the cam surface 71a as the other end portion 73b slips. 71 rotates in the direction of arrow B, while pushing the plunger 75a of the solenoid 75, the interlocking arm 74 rotates in the direction of arrow D, and the blade member 37 rotates in the direction of arrow C to ensure the special winning opening 30. Close (FIG. 4 (b)).

  When the fraudster releases his hand from the transparent glass 6, the rod member 73 is released from being pressed against the one end 73 a, so that the plunger 75 a that has been forcibly pushed in is a spring (not shown) inside the solenoid body. 4), the blade member 37 is rotated in the direction opposite to the arrow C via the shaft 38, so that it again shifts to the open state shown in FIG. The part 73a is moved to the transparent glass 6 side to return to the original position.

  According to the forced closing mechanism in the present embodiment, as described above, even if the fraudulent person pushes the transparent glass 6 and holds the blade member 37 in an open state to illegally enter many game balls, it is transparent. When the glass 6 is pushed in, the blade member 37 is securely closed, so that illegal acts can be reliably prevented. Further, the rod member 73 is disposed in the vicinity of the inner surface of the transparent glass 6, and the illegal operation is ensured by a simple configuration in which the blade member 37 is rotated in the closing direction by the cam member 71 according to the movement of the rod member 73. Therefore, it is possible to reduce the number of parts and reduce costs.

  Furthermore, according to the present embodiment, the cam member 71 can convert the pressing force in one direction of the other end 73b of the rod member 73 into the rotational force in the direction in which the blade member 37 is closed. The structure for forcibly closing the blade member 37 only by rotating the 71 becomes simpler. According to the present embodiment, in the so-called two-type pachinko machine 1, it is possible to reliably prevent an illegal act of holding the blade member 37 in an open state and illegally entering the center accessory 29. it can.

<Second Embodiment>
In the first embodiment described above, the cam member 71 interlocked with the movement of the transparent glass 6 forces the blade member 37 that rotates about the shaft 38 extending in the front-rear direction of the game area 7a to the closed position. Although configured to return, the second embodiment is configured to forcibly return the opening / closing plate 79 as a winning opening / closing member rotating about a shaft 88 extending in the left-right width direction of the game area 7a to the closed position. Will be described with reference to FIGS. 6 is a perspective view showing an outline of the forced closing mechanism in the present embodiment, FIG. 7 is a side view showing the forced closing mechanism in detail, (a) is a closed state of the opening / closing plate 79, (b). Is the open state of the open / close plate 79, and (c) is the state in which the open open / close plate 79 is forcibly closed.

  The second embodiment is applied to a portion of an attacker 84 of a pachinko machine using a so-called first type special electric accessory. The portion of the attacker 84 is the same as that of the center accessory 29 described above. The blade member 37 is hardly affected by the transparent glass 6 being pushed in, but the periphery of the attacker 84 bends through the protruding portion of the attacker unit attached to the game board 77 in a state where the attacker 84 is provided. It is assumed that there is a situation in which the turning operation of the attacker 84 is impaired.

  That is, in the present embodiment, as shown in FIGS. 6 and 7, the unit main body 93 of the attacker unit including the attacker 84 in the opening 92 that penetrates and is formed in a horizontally long rectangular shape on the lower side of the game board 77. Is fitted and fixed. The unit main body 93 is formed with a horizontally-long rectangular opening 78 penetrating and formed, and a rectangular opening / closing plate (winning opening / closing member) 79 is attached so as to open / close with respect to the opening 78 and is transparent. A rod member 81 is provided so that the one end 81 a is brought close to the inner surface of the glass 6. The rod member 81 is closer to the inner surface side of the transparent glass 6 than any gaming parts in the gaming area, and when the transparent glass 6 is improperly pressed, the one end 81a is pressed first. Configured as follows. Further, a hole 80 that penetrates the unit main body 93 is formed at the lower right of the attacker 84 in the unit main body 93, and the rod member 81 penetrates the hole 80 slidably. The attacker 84 is provided in the game area of the game board 77 via the unit main body 93, and is open for a winning ball when winning and constitutes a big winning opening for receiving the gaming ball launched into the gaming area. . The open / close plate 79 is provided in the game area and is configured to open and close by rotating around a horizontal axis 88 of the game area.

  As shown in FIG. 7 (a), the opening / closing plate 79 extends in the left-right width direction of the game board 77 and is rotatably supported by a shaft 88 (see FIG. 6) supported by the unit main body 93. An arm 87 is fixed to the shaft 88 so as to extend obliquely toward the inner lower side of the opening 78. At the inner lower part of the opening 78, a “H” -shaped link member (actuated member) 90 supported rotatably by a shaft 91 is disposed. The link member 90 is rotatably supported on the unit main body 93 side via the shaft 91, with one end portion 90 a having a short distance from the shaft 91 facing the other end portion 81 b of the rod member 81, and The other end 90 b is rotatably supported by a pin 89 together with the arm 87 at the tip of a plunger 86 a of a solenoid 86 positioned and fixed on the unit main body 93 side on the rear side of the opening 78. In the present embodiment, the link member 90 and the rod member 81 constitute a forced closing mechanism.

  Also, on the back side of the game board 77, there is disposed a support member 82 that has a shape that rises upward from the lower side of the hole 80 and has a base fixed to the unit main body 93, and a sliding member formed on the support member 82. The other end 81b of the rod member 81 is slidably passed through the moving hole. A circular plate member 85 is fixed between the back surface of the unit main body 93 of the rod member 81 and the support member 82, and a spring 83 is contracted between the plate member 85 and the support member 82. Yes. As a result, the rod member 81 moves to the game board 77 side (unit body 93 side) against the biasing force of the spring 83 when the one end portion 81a is pressed, and the pressing force to the one end portion 81a is released. Then, the original state is restored according to the urging force of the spring 83. With this structure, the link member 90 applies a pressing force in one direction of the other end portion 81b of the rod member 81 (in the direction of arrow b in FIG. 7C) to close the open / close plate 79 (FIG. 7C). In the direction of arrow c).

  During the game with the pachinko machine having the above-described configuration, the closed state attacker 84 shown in FIG. 7A generates a big hit, and in FIG. 7A, the solenoid 86 from which the plunger 86a is projected is shown in FIG. 7B. As shown in FIG. 4, the arm 87 lifted via the pin 89 causes the opening / closing plate 79 to rotate about the shaft 88 in the direction of arrow a to open the opening 78. The opening / closing plate 79 is temporarily closed when a predetermined number of balls have been won (or a predetermined time has elapsed) since the opening, and this opening / closing operation is executed a predetermined number of times (rounds). Even if the transparent glass 6 is pressed strongly at the time of opening to hold the opening / closing plate 79 in the open position to perform an illegal act, as shown in FIG. 7 (c), when the transparent glass 6 is pressed, Immediately, the one end 81 a is pushed in the direction of the arrow b against the spring 83, and the other end 81 b of the rod member 81 presses the one end 90 a of the link member 90. As a result, the link member 90 rotates counterclockwise about the shaft 91, and the arm 87 is pushed down while the plunger 86 a retracted from the solenoid 86 is pulled out. For this reason, the opening / closing plate 79 is forcibly rotated in the direction of the arrow c and returns to the closing position, so that the opening 78 is reliably closed. Note that the solenoid 86 in the present embodiment is configured so that the plunger 86a is retracted by an urging force of an internal compression spring (not shown), while the plunger 86a is protruded by excitation. The reverse operation of the embodiment is performed.

  Thereafter, when the fraudster releases the transparent glass 6, the rod member 81 is released, and the plunger 86a that has been forcibly pulled out is retracted by the biasing force of the compression spring inside the solenoid body, thereby opening and closing. While the plate 79 is again in the open state shown in FIG. 7B, the rod member 81 moves the one end 81a toward the transparent glass 6 and returns to the original position.

  In the above second embodiment, the link member 90 converts the pressing force in one direction of the other end 81b of the rod member 81 into the rotational force in the direction in which the opening and closing plate 79 is closed. The structure of the mechanism for forcibly closing the opening / closing plate 79 only by rotating 90 can be further simplified, and the apparatus configuration can be simplified and made compact. In addition, it is provided with an attacker 84 that is opened for a winning ball at the time of winning and receives a game ball launched into the game area, and the opening and closing plate 79 rotates around a horizontal axis 88 in the game area. Since the opening / closing operation is performed, it is possible to reliably prevent an illegal act of trying to make an illegal prize for the attacker 84 in the so-called one-type pachinko machine 1.
