Description

  The present invention relates to a movable winning device that is opened and closed when a specific condition such as a big hit state is established, and a gaming machine using the same.

  A pachinko machine installed in a game hall such as a pachinko parlor can give a certain value to a pachinko ball, which is a game medium, and can exchange pachinko balls acquired by playing games for various prizes. In the case of such a pachinko machine, when the operation handle is operated, a launching device provided inside the pachinko machine is driven and a pachinko ball is launched toward the upper side of the game area. The hit pachinko balls flow down the game area while being played by, for example, obstacle nails or windmills. In the process of the pachinko ball flowing down the game area, the normal chucker and starter chucker provided in the game area are won, or they are collected by the out port without winning.

  When the pachinko ball wins the starting chucker, a lottery is performed as to whether or not to shift to a jackpot state where winning is easy to win. When a winning is made in this lottery, an attacker provided in the game area is released. By opening the attacker, the pachinko balls flowing down the game area can easily enter the big prize opening provided in the attacker.

This movable award winning device called an attacker is movable between a device main body provided with a receiving port so as to face the game area, a closed state that closes the receiving port of the device main body, and an open state that leads the pachinko ball to the receiving port. The movable plate in the closed state is switched to the open state in the above-described big hit state. When either a predetermined time elapses after the movable plate is switched to the open state or a predetermined number of pachinko balls are awarded, the movable plate is switched from the open state to the closed state. If a predetermined number of pachinko balls win before the predetermined time elapses, the movable plate is switched to the open state again. In the big hit state, the operation in which the movable plate in the closed state is switched to the open state is completed by performing a preset upper limit number. As described above, when the movable plate is switched to the open state, it is easy to win a large winning opening provided in the apparatus main body, and a lot of pachinko balls as prize balls are paid out.

  However, the movable plate used in such an attacker is switched between a closed state and an open state by rotating about the lower end side of the movable plate, so that the movable plate is switched from the open state to the closed state. At this time, there is a drawback that the pachinko ball is sandwiched between the upper end side of the rotating movable plate and the apparatus body, that is, the pachinko ball is bitten. Since such pachinko balls that have bitten into the ball enter the inside of the device main body from the receiving port, the control device that controls the progress of the game is provided inside the device main body even though the movable plate is in the closed state. There is a drawback that it is considered that it is a prize for winning a big prize, that is, an unfair prize.

  The present invention has been made to solve the above-described problems, and prevents the biting of a pachinko ball that occurs when the movable plate is switched, and can prevent an unfair prize due to the pachinko ball that has been bitten by the ball.

  In addition to the front door unit 4 and the lower unit 5 described above, a game board 30, a launching device (not shown), a payout device (not shown) and the like are assembled to the main body member 3. Although the game board 30 is not shown in detail, a rail decoration frame 31 is assembled on the front surface thereof. By assembling the rail decoration frame 31 from the front of the game board 30, the space inside the rail decoration frame 31 is defined as the game area 32.

  The game board 30 is provided with a structure called a center accessory 35 in the approximate center thereof. Structures such as obstacle nails and windmills are arranged on the peripheral edge of the center accessory 35. In addition, the game board 30 is provided with structures such as winning devices such as a starter chucker 37 and a winning chucker 38. Since these winning devices are well known, the details thereof will be omitted. In addition to these winning devices, the game board 30 is provided with a winning device called an attacker 39. Reference numeral 40 denotes an out port for collecting pachinko balls that have flowed down the game area 32.

  The attacker (movable winning device) 39 is a movable winning device that allows a pachinko ball to be awarded during a big hit state that shifts to a win in a lottery performed when the pachinko ball wins the starting chucker 37. As shown in FIGS. 3 and 4, the attacker 39 includes an attacker main body (apparatus main body) 45, a movable plate 46, and a switching mechanism 47.

  The attacker main body 45 is formed such that a rectangular plate-shaped design plate 50 whose longitudinal direction is the width direction and a box-shaped case 51 provided on the back side of the design plate 50 and extending in the horizontal direction are integrated. ing.

Further, a guide groove (regulator) 54 is provided on the side wall 52b facing the side wall 52a so as to face the guide groove 53. The rotation pin 71 of the movable plate 46 is inserted into the guide groove 54. By inserting the rotation pins 70 and 71 of the movable plate 46 into the guide grooves 53 and 54, the movement direction of the rotation pins 70 and 71 is restricted to the vertical direction of the attacker main body 45.

  In addition, an inclined surface 56 that is inclined downward toward the front surface 50a of the design plate 50 is provided between the front surface 50a of the design plate 50 and the bottom surface 51a of the internal space of the case 51. When the lower end of the movable plate 46 abuts on the guide surface 56), the movable plate 46 is rotated in a direction protruding from the design plate 50 (direction E). Further, the lower end portion of the movable plate 46 rotated in the E direction by the guide surface 56 is brought into contact with the ridge line 57 between the front surface 50 a of the design plate 50 and the guide surface 56.

  The case 51 is provided with a big prize opening 60 in the center of the rear part of the internal space. In addition, inclined surfaces 61 and 62 that are inclined downward toward the special winning opening 60 are provided in the rear portion of the internal space of the case 51. Insertion holes 63 and 64 are provided at both ends in the longitudinal direction of the case 51 from the back surface 51b to the bottom surface 51c of the case 51. Supporting pieces 85 and 86 of the transmission member 80 are inserted into the insertion holes 63 and 64 from the outside of the case 51. Of the end portions of the insertion holes 63 and 64, the width of the end portions 63a and 64a on the lower surface 51c side of the case 51 is larger than the width of the end portion on the back side. In these end portions 63a and 64a, when the movable plate 46 is switched from the closed state to the open state, the support pieces 85 and 86 of the transmission member 80 are inserted, and the connection pieces 73 and 74 of the movable plate 46 are respectively connected. Get in.

  The movable plate 46 is formed in a rectangular plate shape that is substantially the same as the receiving port 52 of the design plate 50. Rotating pins (rotating shafts) 70 and 71 are provided at both ends of the movable plate 46 in the longitudinal direction and at the upper end in the short direction perpendicular to the longitudinal direction. The rotation pins 70 and 71 are provided so as to be coaxial, and the rotation pins 70 and 71 serve as the rotation center of the movable plate 46. Further, at both ends of the movable plate 46 in the longitudinal direction, connecting pieces 73 and 74 projecting rearward of the movable plate 46 are provided at upper ends where the rotation pins 70 and 71 are provided, respectively. These connecting pieces 73 and 74 are provided with connecting pins 75 and 76, respectively. Further, on the front face 46a of the movable plate 46, guide pieces for guiding pachinko balls received when the movable plate 46 is opened to the receiving port 52 of the attacker main body 45 are provided at both ends in the longitudinal direction. 77, 78 are provided.

  The switching mechanism 47 is provided to switch the movable plate 46 between a closed state and an open state. The switching mechanism 47 includes a transmission member 80 and a solenoid (drive source) 81. The transmission member 80 includes support pieces 85 and 86 projecting forward at both ends in the longitudinal direction. Insertion grooves 85a and 86a into which connecting pins 75 and 76 are inserted are provided at the tips of the support pieces 85 and 86, respectively. The transmission member 80 is assembled to the driving iron core 90 of the solenoid 81 using a screw 87 or the like. Reference numeral 88 denotes an insertion hole through which the screw 87 is inserted.

  As is well known, the solenoid 81 includes a driving iron core 90 and a bobbin 91. A stopper 90a is provided at one end of the driving iron core 90, and a compression spring 93 is assembled between the stopper 90a and a bracket 92 that holds the bobbin. By assembling the compression spring 93 between the stopper 90a and the bracket 92, the driving iron core 90 is urged in the A direction. A transmission member 80 is assembled to the other end of the driving iron core 90. The solenoid 81 is driven and controlled by the control device 95. When power is supplied to the solenoid 81 by the control device 95, the driving iron core 90 moves in the B direction against the bias of the compression spring 93, and when the power supply to the solenoid 81 is stopped, the driving iron core 90 is compressed. Due to the restoring force of the spring 93, it moves in the A direction.

  Next, the operation of the attacker configured as described above will be described with reference to FIGS. Since the operations of the rotation pins 70 and 71 and the connection pins 75 and 76 are the same, the operations of the rotation pin 70 and the connection pin 75 will be mainly described below, and the operations of the rotation pin 71 and the connection pin 76 will be described. Is omitted. When a game is not being performed or when a game is being performed but the game has not shifted to the big hit state, power supply to the solenoid 81 by the control device 95 is stopped, so that the movable plate 46 of the attacker 39 is stopped. Is held in a closed state closing the receiving port 52 (see FIG. 5A). As shown in FIG. 6, when the movable plate 46 is in a closed state, the rotation pin 70 is located on the upper end side of the guide groove 53. Further, guide pieces 77 and 78 provided on the movable plate 46 protrude toward the game area 33, and the front surface 46 a of the movable plate 46 is substantially flush with the front surface 50 a of the design plate 50. In this state, the pachinko balls 100 flowing down the game area 33 are not received by the movable plate 46 and flow down as they are.

  For example, when the pachinko ball 100 that plays a game and flows down the game area 33 wins the starter chucker 37, a lottery of whether or not to win is performed, and the game state shifts to a big hit state when it is a win. When shifting to the big hit, the control device 95 starts to supply power to the solenoid 81. By this power supply, the driving iron core 90 moves in the B direction against the biasing force of the compression spring 93. Since the transmission member 80 is fixed to one end of the driving iron core 90, the transmission member 80 also moves in the B direction when the driving iron core 90 moves in the B direction (see FIG. 7). Since the connection pin 75 is inserted into the insertion groove 85a provided at the tip of the support piece 85 of the transmission member 80, when the transmission member 80 moves in the B direction, the connection pin 75 also moves in the B direction.

  Since the relative position of the connecting pin 75 and the rotating pin 70 is fixed, the connecting pin 75 moves in the C direction inside the insertion groove 80a when moving in the B direction. With the movement of the connecting pin 75, the rotation pin 70 moves from the upper end portion of the guide groove 53 toward the lower end portion and along the guide groove 53. As a result, the movable plate 46 moves downward (in the B direction). At this time, the connecting pin 75 moves in the D direction inside the insertion groove 85a.

  When the movable plate 46 moves downward, the lower end of the movable plate 46 contacts the guide surface 56. Since the guide surface 56 is inclined downward toward the front surface 50 a of the design plate 50, the lower end of the movable plate 46 rotates around the rotation pin 70 in the E direction. When the contact between the lower end of the movable plate 46 and the guide surface 56 is released, the back surface 46 b of the movable plate 46 makes point contact at the ridge line 57. Since the movable plate 46 moves in the B direction, the position of the movable plate 46 that makes line contact with the ridge line 57 is shifted toward the upper end side of the movable plate 46. As a result, the movable plate 46 further rotates in the E direction around the rotation pin 70 and protrudes into the game area 33.

  As shown in FIG. 8, when the rotating pin 70 comes into contact with the lower end of the guide groove 53 in the process of moving the movable plate 46 downward, the movement of the movable plate 46 is stopped. On the other hand, since the transmission member 80 moves in the B direction, the movable plate 46 rotates in the E direction around the rotation pin 70. As a result, the movable plate 46 is opened, and the receiving port 52 is exposed (see FIG. 5B and FIG. 9).

  When the movable plate 46 is switched to the open state, the falling pachinko ball 100 is received by the movable plate 46 and then rolls from the receiving port 52 of the attacker 39 to the inside of the attacker 39. Then, the pachinko ball 100 received inside the attacker 39 falls on one of the slopes 61 and 62 and rolls to the big prize opening 60 or directly falls to the big prize opening 60. The pachinko ball 100 that has fallen into the big prize opening 60 is collected after being detected by the detection sensor 96 or the like.

  In the control device 95, the elapsed time from the start of power supply to the solenoid 81 is measured, and the number of detection signals from the detection sensor 96 is counted. For example, the elapsed time is a preset time. Alternatively, when either one of the counts of the detection signals from the detection sensor 96 reaches a preset number, the power supply to the solenoid 81 is stopped. When power supply to the solenoid 81 is stopped, the driving iron core 90 moves upward (in the direction A) by the bias of the compression spring 93. Along with this movement, the movable plate 46 rotates in the F direction. After this rotation, the movable plate 46 moves upward. When the rotation pin 70 of the movable plate 46 comes into contact with the upper end of the guide groove 53, the upward movement of the movable plate 46 is stopped and the rotation in the F direction is stopped.

  At this time, the pachinko ball 100 flowing down the game area 33 flows down along the front surface 46 a of the movable plate 46 by moving the movable plate 46 upward while rotating the movable plate 46 around the upper end side of the movable plate 46. As a result, the pachinko ball 100 is sandwiched between the movable plate 46 and the attacker main body 45, that is, the ball biting can be prevented. In addition, after the movable plate 46 is in the closed state, when a predetermined number of pachinko balls 100 have won the big prize opening 60, the movable plate 46 is switched to the open state again. When the number of times that the movable plate 46 is switched from the closed state to the open state reaches a preset number, or after the movable plate 46 is switched to the open state, a predetermined number of pachinko balls 100 are displayed in the grand prize opening. When a predetermined time has passed without winning 60, the movable plate 46 switched to the closed state does not switch to the open state. Thereby, the jackpot state ends.

  In the present embodiment, the switching mechanism is configured by the transmission member 80 and the solenoid 81, but the configuration of the switching mechanism is not limited to this, and a combination of a plurality of links and solenoids, A combination of a gear and a motor may be used.

  In the present embodiment, an attacker is taken as an example of the movable winning device, but the present invention is not limited to this, and the present invention can be used as long as it is a movable winning device provided in the game area. For example, as shown in FIG. 10, a movable prize apparatus 120 in which a receiving port 125 is provided on a side surface 121 a of the apparatus main body 121 protruding from the game board surface 122 may be used. In this case, the apparatus main body 121 is in a closed state (see FIG. 10 (a)) covering the receiving port 125, and an open state (see FIG. 10 (b)) in which a pachinko ball is fed into the apparatus main body 121 from the receiving port 125. A movable plate 126 that switches between the two is incorporated. Note that the configuration of the switching mechanism that switches the movable plate between the closed state and the open state and the operation of the movable plate when the movable plate is switched by the switching mechanism are the same as in the present embodiment, and thus are omitted here. In FIG. 10, guide pieces 127 and 128 for guiding the pachinko balls received by the movable plate 126 toward the receiving port 125 are provided. In this case, the movable plate without the guide pieces 127 and 128 is provided. There may be.
