Description

  The present invention relates to a ball game machine that uses a game ball to play a game.

In the conventional ball game machine, the game area is provided with a rotating body, and when the ball receiving section provided on the rotating body is at the start position, the game ball is received in the ball receiving section. When the rotating body rotates and the ball receiving unit moves to the end point position, the game ball is discharged from the ball receiving unit (see, for example, Patent Document 1).
JP 2001-46608 A

  However, since the rotating body in the conventional ball game machine described above has been rotated at a constant speed ([angular acceleration of the rotating body] = 0) by driving the motor, the movement of the ball receiving portion is not interesting, and the game The preference regarding the flow-down mode of the sphere was poor.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ball game machine capable of improving the taste with respect to the flow-down mode of game balls.

  A ball game machine according to the invention of claim 1 made to achieve the above object includes a ball guiding member having a ball receiving portion capable of temporarily receiving a game ball flowing down the game area, and a ball receiving portion. Is provided with a shaft portion that rotatably supports the ball guide member so that it can move between the start point position and the end point position, and when the ball receiving portion receives the game ball at the start point position, the ball guide member Is rotated and moved to the end point position so that the game ball is discharged from the ball receiving portion, and the flow-down mode in which the game ball rides on the ball guide member and moves from the start point position to the end point position is configured to be visible. When the game ball is received in the ball receiving portion, the center of gravity of the total weight of the ball guide member and the game ball when the game ball is received is below the horizontal line perpendicular to the axis of the shaft portion. The ball receiving part moves with respect to a vertical line perpendicular to the axis of the shaft part. By placing the ball guide member on the opposite side, the ball guide member rotates by obtaining an angular acceleration due to the rotational moment based on the entire weight, and the angular acceleration of the ball guide member decreases as the ball receiving part moves from the start point position to the end point position. In the ball game machine to be operated, the ball guiding member includes a weight part for generating a rotational moment, and the member for preventing the game ball flowing down from coming into contact with the weight part side of the ball guiding member is weighted. It is characterized by being provided above the part.

  According to the first aspect of the present invention, when the game ball is received in the ball receiving portion at the start position, the position of the center of gravity of the total weight of the game ball and the ball guiding member is orthogonal to the axis of the shaft portion. Since the ball receiving portion is arranged on the lower side of the horizontal line and toward the vertical line, as the ball receiving portion moves from the start point position to the end point position, the center of gravity of the entire weight becomes a vertical line. Moving toward the end (which may eventually pass through the vertical line), the rotational moment for rotating the ball guiding member is reduced. Then, the angular acceleration of the ball guiding member based on the rotational moment decreases, and the falling acceleration of the game ball received by the ball receiving portion decreases. In this way, the mode in which the game ball flows down while the fall acceleration gradually decreases is different from the mode in which the game ball freely falls at a constant acceleration and the mode in which the angular force is 0 when the game ball is forcibly driven and rotated. The player can be given a fresh sensation to improve the taste. Further, it is possible to prevent the game ball flowing down the game area from coming into contact with the weight portion side of the ball guiding member.

  Hereinafter, one embodiment of a pachinko gaming machine to which the present invention is applied will be described with reference to FIGS. As shown in FIG. 1, the gaming board 11 of the pachinko gaming machine according to the present embodiment includes various kinds of objects such as a start winning port 14, a lamp windmill 17, a liquid crystal display device in a gaming area surrounded by guide rails 12. 13, a large winning opening 15, a general winning opening 20, 21 and an obstacle nail 46 are provided. As used herein, the game area refers to an area where the game ball rolls variously due to various types of objects and obstacle nails.

  The start winning opening 14 and the big winning opening 15 are arranged vertically at the lower center position in the game area, and the general winning openings 20 and 21 are on both sides of the start winning opening 14 and the large winning opening 15. One pair is arranged in each. A liquid crystal display device 13 is provided above the start winning opening 14, and a lamp windmill 17 and a start gate 18 are provided on both sides of the liquid crystal display device 13, below the liquid crystal display device 13 and at the start winning prize. Wind turbines 19 and 19 are provided on both sides of the mouth 14. In addition, arc-shaped side lamps 22 and 22 are provided on both side portions along the guide rail 12, and an out port 16 for collecting a loose ball is provided in the lowermost center of the game area. Further, a plurality of obstacle nails 49 (see FIG. 3) are erected over the entire game area.

  As shown in FIG. 1, an upper plate 27A and a lower plate 27B are provided in two upper and lower stages below the game board 11 in the pachinko gaming machine. Then, by operating the operation knob 28 provided at the right end portion of the lower plate 27B, the game balls accommodated in the upper plate 27A are ejected toward the game board 11. Further, if the button 29 provided on the upper plate 27A is pressed, the game ball moves from the upper plate 27A to the lower plate 27B and is accommodated.

  FIG. 2 shows an electrical configuration of the pachinko gaming machine according to the present embodiment. In the figure, reference numeral 50 denotes a main control circuit, which includes a one-chip microcomputer 51 that is packaged with a CPU 51A, ROM 51B, and RAM 51C as a main part. Then, the one-chip microcomputer 51 uses the periodic interrupt pulse received from the periodic reset circuit 53 as a trigger to run various programs stored in the ROM 51B, for example, to perform display control of the liquid crystal display device 13, etc. The game is controlled.

Next, each required part will be described in further detail.
The start gate 18 (see FIG. 1) is provided with a passage through which a game ball can pass through a member protruding from the game board 11. Further, the start gate 18 is provided with a normal symbol start switch 30 (see FIG. 2), and the game ball passing through the start gate 18 is detected by the switch 30. Based on the detection signal, the display object 24 (see FIG. 1) viewed from a 7-segment LED described later is driven.

  The start winning opening 14 corresponds to the “entrance ball opening” of the present invention, and includes first and second starting winning openings 14A and 14B arranged vertically as shown in FIG. Each of the start winning ports 14A, 14B has a so-called pocket structure in which an opening is provided on the upper surface of a member protruding from the game board 11. The game balls that have entered the respective start winning openings 14A and 14B are taken into the back side of the game board 11 through the aforementioned through holes formed in the game board 11.

  More specifically, the upper first start winning opening 14A is set to a width that allows about one game ball to enter. On the other hand, the lower second start winning opening 14B includes movable wing pieces 14C and 14C on both sides. Both the movable wing pieces 14C and 14C are always in an upright state, and the opening width of the second start winning opening 14B sandwiched between the two movable wing pieces 14C and 14C is large enough to contain about one game ball. Is set to be right below the first start winning opening 14A. Thereby, the game ball is not always in the second start winning opening 14B. Then, when the fixed display of the display object 24 viewed from a 7-segment LED described later becomes an odd number, the solenoid provided on the back of the game board 11 is driven to move the movable wing pieces 14C and 14C for a predetermined period (for example, 0. 4 seconds), the game balls that have passed both sides of the first start winning opening 14A are guided to the movable wing piece 14C and can enter the second starting winning opening 14B.

  When a game ball wins one of the first and second start winning openings 14A, 14B (hereinafter simply referred to as "start winning opening 14"), a special symbol start provided in each start winning opening 14A, 14B The switches 31 and 31 (see FIG. 2) detect a game ball, and after the liquid crystal display device 13 displays a plurality of symbols in a variable manner, the display is confirmed. If there is a winning ball in the start winning opening 14 while the liquid crystal display device 13 is variably displayed, up to four winning balls are cumulatively counted.

  As shown in FIG. 1, the special winning opening 15 is formed in a horizontally long shape and is always closed by a movable door 15T. When the pachinko gaming machine is in a “hit state” due to the establishment of a predetermined condition described later, the solenoid 15S (see FIG. 2) provided on the back of the game board 11 is driven, and the movable door 15T is moved to the front side over a predetermined period. Fall down. Thereby, the grand prize opening 15 is opened, and a large number of game balls can be awarded to the big prize opening 15 by using the movable door 15T as a guide. Here, when a period from when the movable door 15T is opened until it is closed is referred to as a “round”, in one round, the opening time of the movable door 15T has reached 29 seconds, or The process ends when any of the 10 game balls has been won or the condition is satisfied first.

  A continuous winning opening and a counting winning opening are provided inside the big winning opening 15, and either one of the continuous winning opening and the counting winning opening is selectively opened. More specifically, when the movable door 15T is opened, the continuous winning opening is initially opened. After winning the continuous winning opening, the continuous winning opening is closed and the counting winning opening is opened. Then, when the jackpot state continuation switch 32 (see FIG. 2) provided in the continuation winning opening detects the winning of the game ball, the next round is continuously executed after the above-mentioned ending condition is satisfied and the round is ended. The Further, when the winning ball count switch 33 (see FIG. 2) provided in the counting winning port detects the winning of the game ball, the winning ball to the big winning port 15 is counted together with the winning ball to the continuous winning port. Then, it is checked whether or not a total of 10 of these has been reached as described above.

  The liquid crystal display device 13 includes a frame body 23 fitted in a substantially rectangular hole formed in the game board 11, and a TFT-LCD module is provided at the back of the frame body 23. As shown in FIG. 3, the liquid crystal display device 13 normally displays three special symbols 13A, 13B, and 13C on the left, the middle, and the right side by side. Each of these special symbols 13A, 13B, and 13C is composed of, for example, a plurality of types that express numbers from “0” to “11”. Usually, each special symbol 13A, 13B, and 13C has a predetermined value. The types are confirmed and displayed on the liquid crystal display device 13. Then, when the game ball is won at the start winning opening 14, the special symbols 13A, 13B, 13C are scrolled in the vertical direction and displayed in a variable manner. After a predetermined time, for example, in the order of left, middle, right Special symbols 13A, 13B, and 13C are stopped and displayed. At this time, for example, when all the special symbols 13A, 13B, and 13C are the same symbol, that is, when they are all in a rough state, the game becomes a “hit state” and the movable door 15T is opened.

  In the frame body 23 provided in the liquid crystal display device 13, the portion extending from the upper side to the upper corners protrudes from the surface of the game board 11, so that the game ball does not enter the frame body 23 from above. It regulates so that.

  As shown in FIG. 1, a display object 24 viewed from a 7-segment LED is provided at the lower left corner of the screen of the liquid crystal display device 13. When the normal symbol start switch 30 (see FIG. 2) provided in the start gate 18 detects the passage of the game ball, the display object 24 viewed from the 7-segment LED is “0” to “9”. After the numbers are variably displayed over a predetermined period, the predetermined numbers are fixedly displayed. Then, when the confirmed and displayed number is an odd number, for example, the movable blade pieces 14C and 14C provided at the start winning opening 14 are operated.

  Four LEDs 25 are arranged at the center of the upper side of the frame 23, and the cumulative number of winning balls to the start winning opening 14 is displayed by turning on the LEDs 25.

  In FIG. 3, the frame body 23 is shown in a state excluding the front decorative plate 100 (see FIG. 1). As shown in FIG. A pair of warp paths 40, 40 through which game balls pass are provided symmetrically. The warp inlet 41 of each warp path 40 opens side by side at the center of the upper side of the frame body 23, while the warp path 40 of the side edge of the frame body 23 has a lower side. The warp outlets 42 are opened inward so as to face each other. Specifically, each warp path 40 extends obliquely downward from the central portion of the upper side of the frame body 23 toward both end portions 101, 101, and toward the back side at both end portions 101, 101 of the upper side. It extends downward along the side of 23. Further, on the side portion of the frame 23 in the warp path 40, protrusions 43 are alternately provided on both inner side surfaces along the longitudinal direction, so that the flow-down speed of the game ball is lowered.

  A stage 79 corresponding to the “ball idler” of the present invention is provided on the lower side of the frame body 23. As shown in FIG. 4, a first ball-spinning path 70 extends in the back portion of the stage 79 so as to connect the above-described warp outlets 42, 42. The second ball idle path 71 extends adjacent to the first ball idle path 70.

  Specifically, the first ball rolling path 70 has a gently curved structure so that the portions near both ends are low and the central portion is high. Thereby, the game ball discharged from the warp outlet 42 flows down toward the both end portions of the first ball turning path 70 and then climbs the slope of the first ball turning path 70, thereby Reduce the speed at the center of the turn 70. In addition, on the lower part near the both ends of the first ball rolling path 70 and the higher part in the center, there are provided gentle slopes 72 and 73 which are substantially flat and slightly inclined forward. ing. Further, a ridge 74 is provided along the front edge of the first ball rolling path 70 between the gentle slopes 72, 72 at both ends and the central gentle slope 73, and the game ball rolls forward. It regulates that.

  On the other hand, the second ball rolling path 71 as a whole is curved so as to gently fall from both end portions toward the central portion, and the central portion is a gentle slope that is substantially flat and slightly inclined forward. 75 is provided. Further, at the portions near both ends of the second ball rolling path 71, there are provided raised portions 76 that slightly protrude from the entire second ball rolling path 71 and whose ridgeline extends in the front-rear direction. The ridge line of the raised portion 76 is located substantially in front of the gentle slope 72 of the first spherical rolling path 70.

  Now, as shown in FIG. 4, an opening 78 is provided at the center in the horizontal direction of the step surface 77 between the first ball rolling path 70 and the second ball rolling path 71 in the lower part of the frame body 23. In the opening 78, a ball guiding member 80 according to the present invention is provided.

  The sphere guide member 80 has a side cross-sectional structure shown in FIG. 6, and is made of a metal main body 80J having a ball receiving portion 81 on the upper end side, and a metal body assembled on the lower end side of the resin main body portion 80J. A weight portion 83 is provided, and is rotatably supported by a shaft portion 82 that penetrates through a substantially intermediate portion between the ball receiving portion 81 and the weight portion 83 in the resin main body portion 80J. Then, the ball guiding member 80 is always held in the basic posture shown in FIG. 6 by a rotational moment in one direction based on the entire weight arrangement of the ball guiding member 80 including the weight portion 83 around the axis J1. ing.

  Here, the weight (weight) of the ball guiding member 80 naturally includes the weight of the ball receiving portion 81 that is a part of the ball guiding member 80. Further, the position of the ball receiving portion 81 when the game ball member 80 is in the basic posture corresponds to the “starting position” of the present invention.

  The axis J1 (see FIGS. 3 and 6) of the shaft portion 82 is parallel to the direction across the opening 78, that is, the game board surface R1 (see FIGS. 3 and 6), and is directed horizontally. The ball guiding member 80 rotates in a vertical plane R2 (see FIG. 6) with respect to the game board surface R1, and the ball receiving portion 81 moves up and down.

  The ball receiving unit 81 is located immediately above the start winning port 14, and thus the ball receiving unit 81 moves toward the start winning port 14 when moving downward. More specifically, the resin main body portion 80J of the ball guiding member 80 has a structure in which the ball receiving portion 81 bulges forward from the upper end portion of the vertical wall 85 that closes the opening 78.

  In this embodiment, in addition to the rotational moment in one direction, as shown in FIG. 6, the lower end portion 103 of the vertical wall 85 is connected to the rear end edge 104 of the wall body constituting the second spherical rolling path 71. The ball guiding member 80 is positioned in the basic posture by contacting the part 105 of the side wall of the ball receiving portion 81 with the front end edge 106 of the wall constituting the first ball rolling path 70. However, this configuration is not always necessary. The wall constituting the first ball rolling path 70 corresponds to “a member for preventing the game ball flowing down from coming into contact with the weight part side of the ball guiding member” of the present invention.

  The ball receiving portion 81 has a concave shape in which the front surface 107 and both side surfaces 108 are surrounded by a wall, and the upper surface 109 and the rear surface 110 are open. Further, at the starting point position, the opening of the rear surface 110 of the ball receiving portion 81 faces the gentle slope 73 of the first ball rolling path 70, and the bottom wall 111 of the ball receiving portion 81 is slightly lower than the gentle slope 73. It has become. Thereby, the game ball rolls into the ball receiving portion 81 from the gentle slope 73.

  As shown in FIG. 8, the weight portion 83 is configured by a shaft body parallel to the axis J1 of the shaft portion 82, and a pair of sandwiching walls 83 </ b> A formed to face the lower end portion of the resin main body portion 80 </ b> J. , 83A. The central portion of the weight portion 83 in the longitudinal direction is constricted in a groove shape, and the protrusion 111 formed on the inner surfaces of the holding walls 83A and 83A is engaged with the constricted portion 113. The constricted portion 113 prohibits a left-right positional shift to the weight portion 83. The pair of sandwiching walls 83A and 83A can be assembled by pushing the weight 83 from the side perpendicular to the axial direction. Therefore, it is easier to assemble the weight portion 83 than when the weight portion 83 is inserted and assembled in the axial direction. Further, both end portions of the weight portion 83 protrude to the side of the ball guiding member 80, and the dead spaces 112 on both sides of the ball guiding member 80 are effectively used.

  The ball guide member 80 rotates using gravity. Hereinafter, a rotational moment for rotating the ball guiding member 80 is obtained. For this purpose, as shown in FIG. 7A, the region including the ball guide member 80 when viewed from the axial direction of the shaft portion 82 is defined as an X axis (hereinafter referred to as “ Horizontal line X ") and a Y axis as a vertical line perpendicular to the axis J1 of the shaft portion 82 (hereinafter referred to as" vertical axis Y "as appropriate). If the upper side is the positive direction of the Y axis and the right side (the back side of the game board 11 from the ball guide member 80) is the positive direction of the X axis, the resin main body 80J as a part of the ball guide member 80 and Table 1 shows the center-of-gravity position coordinates relating to the game balls received by the weight unit 83 and the ball receiving unit 81. Table 1 also shows the weights of the resin main body 80J, the weight 83, and the game ball.

  Here, except for the game balls, the resin main body portion 80J and the weight portion 83 are combined, that is, the ball receiving portion 81 is in the empty ball guiding member 80 (hereinafter referred to as “empty ball guiding member” as appropriate. 80 ”) and the position of the center of gravity are as shown in Table 1. Also, a combination of the game ball, the resin main body portion 80J, and the weight portion 83, that is, the entire ball guide member 80 including the weight portion 83 and the game ball (hereinafter referred to as "game ball receiving state" as appropriate). The weight and the position of the center of gravity of the ball guiding member 80 ”are obtained as shown in the bottom row of Table 1.

Accordingly, the rotational moment M1 applied to the empty ball guiding member 80 is as follows when the clockwise direction in FIG.
M1 = 10.8713 × 0.774 × 9806.65
= 82516.94 [g · mm ² / s ² ]
It is. Due to this rotational moment M1, the ball guiding member 80 rotates in the clockwise direction in FIG. 7A and is pressed against the wall bodies 104, 106 constituting the first and second ball-spinning paths 70, 71. And maintained in the basic posture (that is, the state in which the ball receiving portion 81 is at the start position).

On the other hand, the rotational moment M2 applied to the ball guiding member 80 in the game ball receiving state is:
M2 = 16.3490 × (−1.205) × 9806.65
= −193196.34 [g · mm ² / s ² ]
It is. Thus, the rotational moment M2 applied to the ball guiding member 80 in the game ball receiving state is larger than the rotational moment M1 applied to the empty ball guiding member 80 and is directed in the opposite direction. Thereby, when a game ball is received in the ball receiving portion 81, the ball guiding member 80 rotates counterclockwise in FIG. At this time, the ball receiving unit 81 moves from the start point position to the end point position, and the game ball is discharged from the ball receiving unit 81 at the end point position. The end point position of the present invention is the position of the ball receiving portion 81 when the game ball is received by the ball receiving portion 81 at the start point position and discharged from the start point position by the rotation of the ball guide member 80. Say.

  Next, the angular acceleration when the ball receiving portion 81 is at the start position, that is, when the ball guiding member 80 starts to rotate from the basic posture is obtained. For this purpose, an inertia moment I1 around the center of gravity of the resin main body 80J, the weight 83, and the game ball as a rigid body was obtained, and the center of gravity was concentrated on the center of gravity of the resin main body 80J, the weight 83, and the game ball. The moment of inertia I2 around the shaft portion 82 is obtained as a mass point. The results are shown in Table 2.

From the inertia moments I1, I2 and Steiner's theorem, the inertia moment IS about the shaft portion 82 regarding the ball guide member 80 in the game ball receiving state is obtained.
IS = I1 + I2
= 1760.846 [g · mm ² ]
become. Further, when the ball guiding member 80 in the game ball receiving state rotates from the basic posture (when the ball receiving portion 81 moves from the start point position to the end point position), the angular acceleration A uses the rotation moment M2 as the moment of inertia. Divide by IS
A = M2 / IS = −109.717 [rad / s ² ]
As required. As described above, in this embodiment, the magnitude of the angular acceleration when the ball guiding member 80 starts to rotate is 109.717 [rad / s ² ]. It seems. That is, by changing the weight of the weight part 83 in several stages as shown in Table 3, a plurality of prototypes having different angular accelerations when the ball guiding member 80 starts to rotate are manufactured, and each of the prototypes is manufactured. An experiment was conducted in which the game ball was actually allowed to flow down and the flow-down mode was visually observed.

As a result, when each angular acceleration is too small, the game ball rides on the ball guiding member 80 and moves from the start position to the end position, and the game ball falls from the gentle slope 73 without the ball guiding member 80. It was found that the difference between and cannot be seen. If each angular acceleration is too large, the speed at which the game ball rotates on the ball guide member 80 becomes too slow, so that the ball guide member 80 rotates and the game ball moves from the start position to the end position. In the meantime, it was confirmed that the next game ball flowed down from the gentle slope 73 and collided with the game ball on the ball guiding member 80. Then, the angular acceleration when the ball guide member starts ^{rotating, 70~150 [rad / s 2]} ( ^{specifically, 77.653~141.195 [rad / s 2]} ) If set, the Each angular acceleration was not too small and not too large, and a suitable flow-down mode could be visually recognized. Further, as described above, in this embodiment, the magnitude of the angular acceleration when the ball guiding member 80 starts to rotate is 109.717 [rad / s ² ], and is 70 to 150 [rad / s ² ]. It is in range.

  In the present embodiment, the weight portion 83 is constituted by a shaft body parallel to the direction of the axis J1 of the shaft portion 82. Therefore, by changing the length of the shaft body, the rotation of the ball guiding member 80 is performed. Only the weight of the weight portion 83 can be changed without changing the distance from the center to the weight portion 83, and the acceleration specification can be easily changed.

In addition, the experiment shown in Table 4 is to vary the angular acceleration when the ball guiding member 80 starts to rotate by changing the inclination of the ball receiving portion 81 and changing the position of the center of gravity of the game ball. Also in this case, it was possible to visually recognize a suitable flow-down mode when set to 70 to 150 [rad / s ² ] (specifically, 70.944 to 146.786 [rad / s ² ]).

  Next, the ball receiving unit 81 obtains the transition of the angular acceleration of the ball guiding member 80 while moving from the start point position to the end point position. Therefore, the spherical guiding member 80 is set to “0” in the basic posture of the spherical guiding member 80 and the angular acceleration A is obtained using the data in Tables 1 and 2 described above. The angular acceleration is obtained corresponding to each of the 80 rotation angles. Then, as in the graph shown in FIG. 9, the angular acceleration of the ball guiding member 80 is such that the ball receiving portion 81 moves from the start position (the right end on the horizontal axis in FIG. 9) to the end position (the left side on the horizontal axis in FIG. 9). It turns out that it reduces as it moves to an edge part. The reason for this will be described in conjunction with the operation description to be described later.

  In addition, when required time (cumulative time) until it reaches | attains each rotation angle of the ball guide member 80 is obtained, it is as shown in FIG.

Next, operations and effects of the pachinko gaming machine having the above-described configuration will be described.
When the operation knob 28 is operated and the game balls are continuously blown to the upper part of the game area of the game board 11, the game balls are turned by hitting the obstacle nail 49, the ramp windmill 17, the windmill 19, and the like. Go down the gaming area through a random path.

  As shown in FIG. 3, some game balls enter the warp inlet 41 on the upper side of the liquid crystal display device 13, pass through the warp path 40, and are released onto the first ball rolling path 70. The game ball released on the first ball turning path 70 initially rolls left and right on the first ball turning path 70 with the momentum flowing down the warp path 40. It gradually drops its momentum by climbing the slope. And some of the game balls released on the first ball turning path 70 are left and right on the first ball turning path 70 by a gentle slope 73 provided at the center of the first ball turning path 70. The momentum of rolling is lost, and it rolls on the gentle slope 73 and enters the ball receiving portion 81 of the ball guide member 80 (see FIGS. 5A and 7A). Also, some game balls bounce off the obstacle nails 49 around the liquid crystal display device 13 while flowing down the side of the liquid crystal display device 13 and enter the inside of the liquid crystal display device 13, and some of the game balls Is released onto the first ball rolling path 70 and enters the ball receiving portion 81 in the same manner as described above.

  Here, in a state before the game ball enters the ball receiving portion 81, the center of gravity of the ball guiding member 80 including the weight portion 83 is located at the coordinates (0.774, −6.269) of FIG. (See Table 1). The position of the center of gravity is below the horizontal line X orthogonal to the axis J1 of the shaft portion 82 and on the opposite side of the end point position with the vertical line Y interposed therebetween. In FIG. It acts on the guide member 80, and the ball guide member 80 is held in the basic posture shown in FIG.

  On the other hand, when the game ball enters the ball receiving portion 81, the total center of gravity of the ball guide member 80 including the weight portion 83 and the game ball is set to the coordinates (−1.205, −0. 184) (see Table 1). The position of the center of gravity is below the horizontal line X orthogonal to the axis J1 of the shaft portion 82 and on the end point position side with respect to the vertical line Y. That is, before and after the game ball enters the ball receiving portion 81, the position of the center of gravity moves beyond the vertical line Y perpendicular to the axis J 1 of the shaft portion 82, and thereby the rotational moment applied to the ball guiding member 80. Is changed from the clockwise (rightward) direction in FIG. 7A to the counterclockwise (counterclockwise) direction, and the ball guide member 80 rotates counterclockwise around the shaft portion 82.

When the ball receiving portion 81 moves from the start point position to the end point position due to the rotation of the ball guide member 80, the overall center of gravity of the ball guide member 80 and the game ball moves toward the vertical line Y accordingly. Thereby, the rotational moment for rotating the ball guide member 80 is reduced. Then, as shown in FIG. 9, the angular acceleration of the ball guiding member 80 based on the rotational moment decreases, and accordingly, the falling acceleration of the ball receiving portion 81 decreases. In this way, the mode in which the game ball flows down while the fall acceleration gradually decreases is different from the mode in which the game ball freely falls at a constant acceleration and the flow down mode by a role that is forcibly driven and rotates with an angular acceleration of 0, The player can be given a fresh sensation to improve the taste. Further, in the present embodiment, the magnitude of the angular acceleration of the ball guiding member 80 when the ball receiving unit 81 starts moving from the start position where the game ball is received to the end position is 109.717 [rad / s ² ]. By setting, it is possible to give a profound feeling to the operation of the ball guiding member 80.

  Then, when the ball receiving unit 81 reaches the end point position by the rotation of the ball guiding member 80, the game ball is discharged from the ball receiving unit 81. Then, the direction of the rotational moment applied to the ball guiding member 80 is changed, and the ball guiding member 80 is returned to the original posture. This operation is like a lion dance and improves the taste.

  Here, the game ball is stopped by entering the ball receiving portion 81 from a state of randomly rotating on the first ball rotation path 70, and the game ball is rotated by the rotation of the ball guide member 80. Is guided toward the start winning opening 14 just below the ball receiving portion 81. Then, since the game ball is discharged from the ball receiving unit 81 toward the start winning opening 14 on the extension line in the guide direction, when the game ball enters the ball receiving unit 81, it enters the ball receiving unit 81. Instead, the probability of winning at the start winning opening 14 is higher than the case of flowing down from the stage 79 in a random direction. Therefore, when a game ball enters the ball receiving portion 81, the expectation of entering the ball to the start winning opening 14 is increased. In addition, when the game ball passes through the warp path 40 and is released onto the first ball rotation path 70, the possibility that the game ball enters the ball receiving unit 81 is increased. Thus, the player can have a sense of expectation, and the game performance can be improved.

  Note that the game ball that has swung down on the second ball rolling path 71 enters, for example, the start winning opening 14 or contacts the ball receiving portion 81 that has moved to the end position, thereby starting the starting winning opening. The game ball plays various roles such as preventing the game ball from entering 14 and the movement of the game ball becomes complicated, thereby improving the game's preference.

  Thus, according to the pachinko gaming machine of this embodiment, the game ball is guided by being held by the ball receiving portion 81 of the ball guide member 80 and discharged in a certain direction, so that the flow direction of the game ball is reduced. Is limited to some extent, a flow mode different from the case where the game ball flows down in a random direction without entering the ball receiving portion 81 is added, and variations in the flow mode of the game ball can be increased. In addition, at this time, the game ball is guided to drop while reducing the acceleration, so that the game ball is free-falling at a constant acceleration or different from the flowing-down mode by an accessory that is forcibly driven and rotated at an angular acceleration of 0, The player can be given a fresh sensation to improve the taste. In addition, the ball guiding member 80 rotates in a vertical plane with respect to the game board 11, and since there is no accessory performing such an operation in the conventional ball game machine, it provides a novel game effect. be able to. Furthermore, in the present embodiment, the game balls are made to idle in various ways on the first ball turning path 70 and then flow down again to enter the ball receiving portion 81. The movement of the game sphere until it flows down through the part 81 becomes complicated, and the preference of the game effect can be enhanced.
