And a plunger 102 that can move linearly between these positions. A piston portion 102 a that engages between the engaging finger portions 71 c provided on the first arm 61 described above is provided at the distal end portion of the plunger 102. As shown in FIG. 7, the plunger 102 has an A position (first position) where the plunger 102 protrudes from a neutral position, a B position (second position) which is a neutral position, and a plunger 102 from the neutral position. A linear movement is possible along the longitudinal axis direction (X direction in FIG. 7) at three positions, ie, the C position (third position) that has been sucked.

  When the plunger 102 is held at the neutral position B and is energized by applying a pulse voltage to one of the plurality of coils in the solenoid 101, the plunger 102 is generated by the generated magnetic field. Receives magnetic force and moves toward the A position. Even if energization to the coil is stopped in a state where the plunger 102 protrudes to the A position, the plunger 102 is held at that position by the permanent magnet. When a pulse voltage is applied to the one coil in the reverse direction with the plunger 102 protruding to the A position, the plunger 102 returns to the B position, which is a neutral position. And the plunger 102 which returned to B position is hold | maintained at the position with a permanent magnet, even if the electricity supply to a coil is stopped.

  On the other hand, when a pulse voltage is applied to the other coil in the solenoid 101 while the plunger 102 is in the B position, the plunger 102 receives the magnetic force by the generated magnetic field and moves toward the C position. Even if the power supply to the coil is stopped while the plunger 102 is attracted to the C position, the plunger 102 is held at that position by the permanent magnet. When a pulse voltage is applied to the other coil in the reverse direction while the plunger 102 is attracted to the C position, the plunger 102 returns to the B position, which is a neutral position. And the plunger 102 which returned to B position is hold | maintained at the position with a permanent magnet, even if the electricity supply to a coil is stopped. In this way, the movement position of the plunger 102 (movement position of the piston portion 102a at the tip of the plunger 102) can be controlled by selecting the coil to which the voltage is applied and the direction in which the voltage is applied to the coil. The plunger 102 can be held at a specific position without continuously supplying power.

  Here, the control of the opening / closing operation of the door 51 and the control of the displacement displacement operation of the seesaw 80 using the driving force transmission mechanism 60 configured as described above will be described.

  As shown in FIG. 8, when the piston portion 102a of the plunger 102 is at the A position, the open / close door 51 is upright. At this time, the open / close door 51 is in a closed position for closing the winning opening 43. Then, when the piston portion 102a of the plunger 102 is moved leftward so as to be located at the B position from the state where it is located at the A position, as shown in FIG. 9, the first arm 61 and the second arm 62 move the rotation shaft 62c. It rotates integrally counterclockwise as the center. At this time, the arm portion 62b of the second arm 62 rotates counterclockwise about the rotation shaft 62c, and the door opening / closing arm 52 is pressed by the engagement piece 62d. Therefore, the pivot shaft 51b having the door opening / closing arm 52 at the tip pivots clockwise so that the opening / closing door 51 tilts forward with respect to the mounting plate 42 about the pivot shaft 51b (in the direction of arrow R). (See Fig. 9).

  When the door 51 is tilted forward until the door 51 is in a substantially horizontal state in a side view, the edge 51a of the door 51 abuts against the mounting plate 42 as shown in FIG. Rotation in the direction of arrow R further than the substantially horizontal position is restricted. For this reason, the counterclockwise rotation about the rotation shaft 62c of the engaging piece 62d is restricted, and the first arm 61 and the second arm 62 are prevented from rotating integrally in the counterclockwise direction. .

  Further, when the plunger 102 moves to the left so that the piston portion 102a of the plunger 102 is positioned from the B position to the C position, as shown in FIG. 10, the second arm 62 remains held at the rotational position shown in FIG. Only the first arm 61 rotates counterclockwise about the rotation shaft 62c against the urging to rotate the first arm 61 by the torsion spring 63 in the clockwise direction.

  Next, the state of the distributed displacement operation of the seesaw 80 while the piston portion 102a of the plunger 102 linearly moves from the A position through the B position to the C position as described above will be described with reference to FIGS. . First, when the piston portion 102a of the plunger 102 moves between the A position and the B position, as shown in FIG. 11, the cam having a small diameter from the axial center of the cam shaft member 65 of the disc cam portion 66. The surface 66 a contacts the contact portion 81 of the seesaw 80. Therefore, the seesaw 80 is biased upward by the torsion spring 68 on the second ball passage opening 112 side, and tilts downward from the second ball passage opening 112 side toward the first ball passage opening 111 side. To do.

  On the other hand, when the piston portion 102a of the plunger 102 moves between the B position and the C position, the cam surface 66a having a small diameter from the axis of the cam shaft member 65 of the disc cam portion 66 is in contact with the seesaw 80. The state of contact with the contact portion 81 (see FIG. 12) and the rotation of the disc cam portion 66 causes the contact portion 81 to exceed the inflection point H from the axis of the cam shaft member 65 of the disc cam portion 66. The cam surface 66b having a large diameter changes to a state in which the cam surface 66b comes into contact with the contact portion 81 of the seesaw 80 (see FIG. 13). As shown in FIG. 13, in a state where the cam surface 66 b is in contact with the contact portion 81 of the seesaw 80, the disc cam portion 66 resists the seesaw 80 from being biased by the torsion spring 68 via the contact portion 81. Therefore, the seesaw 80 is inclined downward from the first ball passage opening 111 side toward the second ball passage opening 112 side.

  For this reason, in the process in which the piston portion 102a of the plunger 102 moves between the B position and the C position, the seesaw 80 tilts downward from the second ball passage opening 112 side toward the first ball passage opening 111 side. By changing with the rotation of the camshaft member 65, the state of the seesaw 80 is inclined downward from the first spherical passage opening 111 side toward the second spherical passage opening 112 side. The game ball dropped into the winning space 44 from the winning opening 43 is more easily guided by the first ball passage 121 than the second ball passage 122, and the second ball compared to the first ball passage 111 side. It changes to the state where it is easier to be guided by the ball passage 122.

  Here, an outline of a control system for controlling the pachinko machine PM will be described. As shown in FIG. 14, the present control system includes ball detection sensors 131 and 132, start winning sensors 133, solenoid relay board 800, solenoid 101, and symbol display device, which are game board side electrical components disposed on the game board 20. 28 and the above-mentioned main board 700 which is a frame-side electric component disposed on the back set board 30, and these are electrically connected by a cable or the like.

  That is, the main board 700 is connected to the start winning sensor 133, and a detection signal (start signal) from the start winning sensor 133 is input to the main board 700. The solenoid 101 is connected to the main board 700 via the solenoid relay board 800, and a solenoid drive signal from the main board 700 is input to the solenoid 101 via the solenoid relay board 800 to drive the solenoid 101. It has become. Further, when a symbol display signal from the main board 700 is input to the symbol display device 28, the symbol display device 28 is activated to display a variable display of symbols in a plurality of symbol display units.

  The main board 700 includes a system program that manages the entire operation of the pachinko machine PM, a storage unit that is pre-stored with a game execution program, and a microprocessor that executes these programs (hereinafter, “ And a random number generator 720 that generates random numbers for symbol lottery (for example, 65536 random numbers from 0 to 65535) irrespective of the control of the main board 700. ing.

  The CPU 711 has a symbol lottery means B73. When the main board 700 detects a low signal (start signal) from the start winning sensor 133, the symbol lottery means B73 acquires one count value of 65536 random numbers generated sequentially from the random number generator 720. Thus, the stop symbol in the symbol display device 28 is determined.

  In addition to the CPU 711 described above, the control unit 710 is provided with a ROM 712, and a control program to be executed by the CPU 711 and data necessary for the control process are described in the ROM 712. Of these necessary data, for example, symbol data for determining a stop symbol in the symbol display device 28 is recorded in the symbol data table B74. Each symbol data is given an address number, and one symbol data is specified from one address number. As described above, when the low signal (start signal) from the start winning sensor 133 is detected, the count value for the symbol lottery selected from the random numbers generated by the random number generator 720 and the symbol data in the symbol data table B74 are displayed. The stop symbol is selected by collation. Then, a predetermined symbol selected based on the symbol display signal from the main board 700 is displayed on the symbol display device 28.

  As described above, a “special symbol” (for example, “147”, “258”) composed of a three-digit pattern or a combination of numbers selected based on the lottery result by the symbol lottery means B 73 is displayed on the symbol display device 28. Although this special symbol is displayed on the liquid crystal screen, a symbol consisting of a combination of the same type of all three digits (for example, “111”, “777”) is referred to as a “big hit symbol”.

  Next, an outline of the game in the pachinko machine PM will be described with reference to the flowcharts of FIGS. 15 and 16. In the flowcharts shown in FIGS. 15 and 16, the portions of the circle A are connected to form one flowchart, and the portions of the circle B are connected to each other.

  First, when a player operates the operation handle 8, a hit ball is shot on the game board 20. The hit ball falls on the game board 20 while contacting a nail or the like (not shown) provided on the game board 20. Then, when the start winning tool 26 is won (step S1) or the general winning tool 25 is won (step S20) in the process of falling, a predetermined number (for example, five balls) of winning balls are obtained from the winning ball payout exit 6b. It is paid out to the player (step S2 or step S21).

  If the number of reserved balls stored in the control unit 710 is zero when the start winning tool 26 has been won, the following symbol variation process is not executed, while the number of reserved balls When is 1 or more and 4 or less, 1 is subtracted from the number of reserved balls (step S3). Based on the detection signal output from the start winning sensor 133, a predetermined number (for example, five balls) of winning balls are paid out from the winning ball payout exit 6b, and a control signal is sent from the main board 700 to the symbol display device 28. The symbol display device 28 is actuated and symbol variation display is started (step S4). Note that when the hit ball is won in the start winning tool 26 during the symbol variation display on the symbol display device 28, the maximum number of reserved balls is stored in the control unit 710, and the stored number of reserved balls is stored. Thereafter, the subsequent operation of the symbol display device 28 is guaranteed. The stored number of reserved balls can be recognized by the player when the special symbol holding lamps 29, 29, 29, 29 on the game board 20 are turned on.

  In subsequent step S5, the symbol lottery means B73 acquires one count value from the random numbers generated by the random number generator 720, and selects a stop symbol corresponding to the count value. Then, a predetermined symbol selected based on the symbol display signal from the main board 700 is displayed on the symbol display device 28 (step S6).

  At this time, it is determined whether or not the count value acquired by the symbol lottery means B73 is a predetermined winning value (step S7), and unless it is the predetermined winning value, that is, the symbol display device 28 is stopped and displayed. Unless the symbol is a predetermined jackpot symbol, the solenoid 101 is not energized because the solenoid drive signal is not output from the main board 700 to the solenoid 101, the open / close door 51 remains upright, and the open / close door 51 is closed. (Step S8). In such a closed state of the open / close door 51, the game ball cannot enter the winning space 44, so that the game ball falling on the game board 20 does not win the big prize device 50 and enters the lower outlet 27. It reaches.

  On the other hand, when the count value acquired by the symbol lottery means B73 is a predetermined winning value, that is, when the special symbol that is stopped and displayed as a result of symbol variation in the symbol display device 28 is a predetermined jackpot symbol. , "Big hit game" occurs. Then, a solenoid drive signal is output from the main board 700 to the solenoid 101, the solenoid 101 is energized, the piston portion 102a of the plunger 102 moves so as to be located at the B position, and the opening / closing door 51 that is normally in the closed position is opened. Rotating to a predetermined forward tilted position, the big prize device 50 is in an open state (step S9). In such an open state, the open / close door 51 receives the game ball falling on the game board 20, and the game ball can enter the winning space 44. At this time, as shown in FIG. 12, the seesaw 80 is inclined downward from the second ball passage opening 112 side toward the first ball passage opening 111 side.

  When the seesaw 80 is in such a posture, among the game balls that are received in the winning space 44 and fall on the seesaw 80, the game balls are guided by the wall surface 113 of the sensor unit 110, and the seesaw 80 is moved to the right. The rolling game ball passes through the ball receiving portion 47 and then enters the second ball passage 122. At this time, the game ball passes through the detection hole 132a of the ball detection sensor 132 provided in the second ball passage 122 and is detected (step S10), and a predetermined number (from the prize ball payout exit 6b) ( For example, 15 prize balls are paid out (step S11).

  On the other hand, among the game balls that are received in the winning space 44 and fall on the seesaw 80, the game balls that are guided by the wall surface 113 of the sensor unit 110 and roll leftward on the seesaw 80 are on the ball receiving unit 46. After passing through, it enters the first ball passage 111 (see FIG. 17). At this time, the game ball passes through the detection hole 131a of the ball detection sensor 131 provided in the first ball passage 111 and is detected (step S10), and a predetermined number (from the prize ball payout exit 6b) ( For example, 15 prize balls are paid out (step S11). Further, when the game ball passes through the detection hole 131a of the ball detection sensor 131, a solenoid drive signal is output from the main board 700 to the solenoid 101, the solenoid 101 is energized, and the piston portion 102a of the plunger 102 is moved to the C position. Move to be located at. At this time, as shown in FIG. 13, the seesaw 80 is inclined downward from the first ball passage opening 111 side toward the second ball passage opening 112 side.

  It is determined whether or not a predetermined time (for example, 30 seconds) has elapsed since the big winning device 50 is opened, or whether or not a predetermined number (for example, 10 balls) of winning is detected by the ball detection sensors 131 and 132 (step). S12), when any of the conditions is satisfied, it is closed once (step S13). At this time, the piston portion 102a of the plunger 102 moves from the C position to the A position, and the seesaw 80 moves from the second ball passage opening 112 side to the first ball passage opening 111 side as shown in FIG. Return to the state of tilting downward.

  When it is determined that there is a winning in the second ball passage 122 (specific area) while the big winning tool 50 is open (step S14), the big winning tool 50 is temporarily set as described above. After closing it will be opened again. Thereby, the opening of the big prize device 50 can be continued a predetermined number of times (for example, 16 times). In addition, when the big winning tool 50 has been opened a predetermined number of times (for example, 16 times) or when there is no winning in the second ball passage 122 during the opening of the big winning tool 50 (step S15), this jackpot The game ends.

  As described above, in the first embodiment, the operation of the door and the sorting member can be controlled using one solenoid as a drive source, so that the cost of the winning device can be kept low. it can. In addition, by using one drive source as described above, it is possible to downsize the winning device vertically or horizontally, and by using the space on the game board that can be secured by downsizing, It becomes easy to install the symbol display device. Furthermore, since not only the symbol display device but also other winning devices can be installed by effectively utilizing the space, the degree of freedom in designing the game board can be increased.

  Here, a second embodiment of the winning device for a ball game machine according to the present invention will be described with reference to FIGS. In the present example, the same parts as those in the first embodiment are denoted by the same reference numerals, and the differences will be briefly described mainly. 18 is a perspective view of the inside of the winning device in the second embodiment, and FIG. 19 shows the state of the seesaw when the plunger provided in the winning device in the second embodiment is located at the A position. FIG. 20 is a view showing the state of the seesaw when the plunger provided in the winning device in the second embodiment is located at the B position, and FIG. 21 is provided in the winning device in the second embodiment. It is a figure which shows the mode of the seesaw when the made plunger is located in C position.

  As shown in FIG. 18, the driving force transmission mechanism 160 in the present embodiment has a first cam portion 66 and a second cam portion 167 that abut on the seesaw 80, and is a camshaft member that is rotatably disposed. 65, a first arm 61 that is attached to the camshaft member 65 and engages with the plunger 102 to rotate the camshaft member 65 in accordance with the linear movement of the plunger 102, and a rotation shaft 51b on the left side of the open / close door 51. In addition to a U-shaped door opening / closing arm 52 provided at the front end and a second arm 62 provided on the camshaft member 65 so as to be relatively rotatable and engaged with the door opening / closing arm 52, a first arm 61 and a second arm 62 are also provided. And a torsion spring 63 for connecting the two.

  In addition, the driving force transmission mechanism 160 is configured, the first cam portion 66 having an inflection point H and the outer periphery formed in a deformed eccentric disc shape, and the inflection point I and the outer periphery having a deformed eccentric shape. The second cam portion 167 formed in a disk shape is fixedly provided at a predetermined interval in the longitudinal axis direction of the camshaft member 65. The cam surface of the first cam portion 66 is formed with cam surfaces 66a and 66b having different diameters from the axis of the camshaft member 65 at the inflection point H, and the cam surface of the second cam portion 167 is formed. Are formed with cam surfaces 167a and 167b having different diameters from the axial center of the camshaft member 65 with the inflection point I as a boundary. The first cam portion 66 and the second cam portion 167 are rotatable in the rotation direction around the cam shaft member 65 as the cam shaft member 65 rotates.

  The flat seesaw 80 that guides the game balls introduced into the winning space 44 through the winning openings 43 in either the left or right direction includes the first ball passage opening 111 side and the second ball passage opening. It extends to the left and right between the 112 side. A mounting hole 83 for inserting the swing shaft 82 of the seesaw 80 is provided in the lower part of the seesaw 80. One end of the swing shaft 82 is attached to a mounting hole (not shown) provided on the housing 41 side, and the seesaw 80 has the swing shaft 82 substantially perpendicular to the camshaft member 65 in the longitudinal direction as a swing center. It is configured to be swingable up and down (in the direction of arrow Y).

  In addition, on the lower surface of the seesaw 80, a protruding projecting portion 81 projecting downward is provided extending left and right, and the cam surface of the first cam portion 66 is disposed on the projecting portion 81 (first contact portion). 81a), and similarly, the cam surface of the second cam portion 167 contacts the contact portion 81 (second contact portion 81b).

  Of the cam surfaces of the first cam portion 66, the cam surface 66 a having a small diameter from the axial center of the cam shaft member 65 contacts the contact portion 81 a of the seesaw 80, and among the cam surfaces of the second cam portion 167. When the cam surface 167b having a large diameter from the axial center of the camshaft member 65 comes into contact with the contact portion 81b of the seesaw 80, the seesaw 80 is opened from the second ball passage opening 112 side to the first ball passage opening 111. Tilt down to the side. On the other hand, among the cam surfaces of the first cam portion 66, the cam surface 66 b having a large diameter from the axial center of the cam shaft member 65 contacts the contact portion 81 a of the seesaw 80, and among the cam surfaces of the second cam portion 167. When the cam surface 167a having a small diameter from the axial center of the camshaft member 65 comes into contact with the contact portion 81b of the seesaw 80, the seesaw 80 is opened from the first ball passage opening 111 side to the second ball passage opening 112. Tilt down to the side. As described above, as the cam shaft member 65 rotates, one of the cam surfaces 66 a, 66 b, 167 a, 167 b of the first cam portion 66 and the second cam portion 167 comes into contact with the seesaw 80. The seesaw 80 is configured to incline to the left or right depending on whether it contacts the portion 81.

  Next, in the present embodiment, the state of the sorting displacement operation of the seesaw 80 while the piston portion 102a of the plunger 102 moves from the A position to the C position through the B position will be described with reference to FIGS. To do. First, when the piston portion 102a of the plunger 102 moves between the A position and the B position, the diameter of the first cam portion 66 from the axial center of the cam shaft member 65 is the second as shown in FIG. A cam surface 66 a smaller than that of the cam portion 167 contacts the contact portion 81 a of the seesaw 80. For this reason, the seesaw 80 is inclined downward from the second ball passage opening 112 side toward the first ball passage opening 111 side.

  On the other hand, when the piston portion 102a of the plunger 102 moves between the B position and the C position, the diameter of the first cam portion 66 from the axis of the cam shaft member 65 is larger than that of the second cam portion 167. When the small cam surface 66a is in contact with the contact portion 81a of the seesaw 80 (see FIG. 20), and when the first cam portion 66 is rotated, the contact portion 81a exceeds the inflection point H and the first cam portion 66 is reached. The cam shaft member 65 is in a state where the cam surface 66b having a larger diameter from the axial center of the cam shaft member 65 than that of the second cam portion 167 contacts the contact portion 81a of the seesaw 80 (see FIG. 21). Changes with rotation. At this time, with the rotation of the second cam portion 167, the contact portion 81b exceeds the inflection point I, and the diameter of the second cam portion 167 from the axis of the cam shaft member 65 is larger than that of the first cam portion 66. The smaller cam surface 167a comes into contact with the contact portion 81b of the seesaw 80.

  For this reason, in the process in which the piston portion 102a of the plunger 102 moves between the B position and the C position, the seesaw 80 tilts downward from the second ball passage opening 112 side toward the first ball passage opening 111 side. With such a posture, the first cam portion 66 pushes up the seesaw 80 through the contact portion 81a, so that the first cam portion 66 tilts downward from the first ball passage opening 111 side toward the second ball passage opening 112 side. Change to posture. Therefore, the game ball that has fallen into the winning space 44 from the winning opening 43 is more easily guided by the first ball passage 121 than the second ball passage 122, and the first ball passage 121 is more than the first ball passage 121. The two-ball path 122 changes to a state where it can be easily guided.

  As described above, in the second embodiment as well, in the same way as in the first embodiment, the operation of the opening and closing door and the sorting member can be controlled using one solenoid as a drive source. The cost of the winning device can be kept low. In addition, the winning device can be downsized vertically or horizontally, and it becomes easy to install a large symbol display device using the space on the game board that can be secured by downsizing. Furthermore, since not only the symbol display device but also other winning devices can be installed by effectively utilizing the space, the degree of freedom in designing the game board can be increased.
