JP 2005-46218 A

  However, any of the above rotating bodies has a constant degree of expectation after receiving the balls and is poor in change.

  The present invention has been made on the basis of the above-described background, and provides a pachinko gaming machine distribution device including a rotating body that can change the ratio of guiding a ball in a specific direction depending on the game state and can give the player interest. This is the issue. In addition, a pachinko gaming machine including the distribution device is provided.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problems, the present invention has a plurality of rotating bodies that rotate around a common rotation axis, and a ball received in a ball receiving portion formed in the circumferential direction of the rotating bodies in a plurality of directions. A distribution device for pachinko machines that distributes to
It has a position displacement means for changing the relative positional relationship between a plurality of rotating bodies arranged so as to be in a stacked state and changing the proportion of balls received in each direction.

  The sorting device according to the present invention has a plurality of rotating bodies, and distributes balls received in the receiving unit in a plurality of directions. About the some rotary body in a lamination | stacking state, the ratio which distributes the received ball | bowl to each direction can be changed by changing the relative positional relationship. For example, it is possible to give interest to the player by changing the ratio of guiding the ball to a specific winning opening (for example, a starting winning opening) advantageous to the player.

  In that case, a distribution apparatus can be comprised as what has two rotary bodies provided in a lamination | stacking state. The position displacing means can displace the relative positions of the two rotating bodies in the rotational direction according to the state of the game. In this way, according to the state of the game, for example, when the probability change state is advantageous for the player, the relative position in the rotational direction of the two rotating bodies can be displaced. In the probability variation state, for example, the interest of the game can be enhanced by increasing the ratio of guiding the ball to a specific winning opening.

  Further, at that time, the distribution device is provided adjacent to the first rotating body having a disk shape and a plurality of first notches formed at predetermined intervals in the circumferential direction, A plurality of second cutout portions are formed in the circumferential direction, and a circumferential interval between the second cutout portions is a circumferential interval between the first cutout portions except a part of the plurality of second cutout portions. And a second rotating body formed substantially equally. The accepting portion is a hit accepting portion capable of guiding the ball received by matching the first notch portion and the second notch portion in the direction of a specific winning opening provided on the game board of the pachinko gaming machine, Since the first cutout portion and the second cutout portion do not coincide with each other, a ball receiving portion that can guide a ball received only by the first cutout portion in a direction other than the specific winning opening can be included. Further, the position displacing means includes a first position where a part of the plurality of first cutout portions and the second cutout portion coincide with each other, and a ratio at which the plurality of first cutout portions and the second cutout portion coincide with each other than the first position. The relative position in the rotation direction between the first rotating body and the second rotating body can be displaced between the second position where there are many.

  In this way, a relative receiving position in the rotational direction between the first rotating body and the second rotating body is displaced between the first position and the second position, and a hit receiving portion capable of guiding the ball in the direction of a specific winning opening is provided. By increasing the proportion of the first cutout portion and the second cutout portion to be formed, it is possible to increase the proportion of guiding the ball in a direction advantageous to the player. Thereby, it becomes a distribution apparatus provided with the rotating body which has not been made so far, and it can give interest to the player.

  Further, at that time, the first rotating body and the second rotating body are integrally rotated at either the first position or the second position, and the driving means integrally rotates. When the first rotating body and the second rotating body are in a predetermined angle posture, the ball received in the hit receiving portion is given a specific winning opening with a higher probability than the ball not passing through the sorting device. It can be provided with a leading outlet. Further, the specific winning opening may be a starting winning opening provided on the game board surface. A conventional pachinko gaming machine has a movable member (so-called electric tulip) that has a closed state and an open state at the upper part of the start winning opening. By making the length longer, it is possible to play a game that is more advantageous than the normal state, but if the sorting device equipped with the rotating body of the present invention is adopted, the winning prize at the start winning opening is provided without providing an electric tulip. The rate can be improved.

  Further, at least one of the first rotating body and the second rotating body is formed with a guide groove having a predetermined angular width, and at least the other is formed with a protrusion that slidably engages with the guide groove so as to drive the first rotating body. When the means rotates the first rotating body, the second rotating body is driven in conjunction with the first rotating body in a state where the protrusion slides within the angular width and engages with one end of the guide groove. Rotating to displace the relative position in the rotational direction of the first rotating body and the second rotating body to the first position or the second position, and the driving means of the second rotating body rotationally driven the second rotating body In this case, the first rotating body is driven to rotate in conjunction with the second rotating body in a state where the protrusion slides within the range of the angular width and engages with the other end of the guide groove. Displace the relative position of the rotating body in the rotation direction to the second position or the first position, Groove de, driving means of the protrusions and the first rotating member or the guide groove, the drive means of the projecting portion and the second rotary member can be made to function as a position displacement means.

  In this way, the protrusion slides and engages with the guide groove, and the relative position in the rotational direction between the first rotating body and the second rotating body is displaced within a range of a predetermined angular width, thereby the first position and the second position. It can be displaced between positions. When one of the first rotating body or the second rotating body is driven, the other rotating body is driven to rotate, so that the rotating bodies are integrated with each other while maintaining the first position or the second position. It can be rotated in synchronization. Further, the drive means can also be constituted by one drive motor.

  Further, the pachinko gaming machine of the present invention includes the above-described sorting device, a jackpot generating means for generating a jackpot when a predetermined jackpot condition is satisfied, and after the jackpot generated by the jackpot generating means is completed than in a normal state. Special state generating means for generating a special state advantageous to the player is provided. The special state generating means can displace the relative position between the first rotating body and the second rotating body from the first position to the second position by the position displacing means during the special state. Thus, in the special state (for example, the probability variation state), the relative position of the first rotating body and the second rotating body to the second position where the ratio of guiding the ball in the direction of a specific winning port (for example, the starting winning port) is increased. Can be displaced, and the winning rate to the start winning opening can be increased.

In addition, the payout control board 29 controls the payout device 43 for winning balls or rental balls according to the control signal. Similarly, the launch control board 30 controls the ball launching device 44.

  FIG. 3 is a perspective view of a main part of the accessory device 6. The accessory device 6 is configured by a single housing (housing) having a cylindrical shape with an open front surface and extending in the front-rear direction, and is attached to the game board 3. The accessory device 6 has a top wall 6a formed in a mountain shape with a high center, and side walls 6b and 6b extending vertically downward from the lower end of the top wall 6a. In the left and right side walls 6b, 6b, ball receiving ports 61, 61 capable of receiving balls in the accessory device 6 are provided, respectively. And guide rods 62 and 62 that communicate with the ball receiving ports 61 and 61 and guide the balls to the rear in the accessory device 6 are attached to the inner sides of the side walls 6b and 6b, respectively.

  A corrugated stage surface 63 is provided below the accessory device 6. The trough 63a (three places in this example) which is the lowest part of the waveform of the stage surface 63 is the front side (the glass door 2 side of the pachinko gaming machine 1 is the front side, and the side corresponding to the back side of the base is the rear side. It is slightly inclined so as to be lower on the front side). The sorting device 70 is disposed on the front side of the central valley portion 63 a of the stage surface 63.

  FIG. 4 is a main part plan view of the accessory device 6 mainly showing the sorting device 70. 5 is a YY sectional view of FIG. 4, and FIG. 6 is a ZZ sectional view of FIG. The sorting apparatus 70 includes a bottomed cylindrical enclosure wall 71 whose upper surface is open, and a disk-like upper stage rotating body 72 (first rotating body) accommodated and disposed in a stacked state above and below the surrounding wall 71. Similarly, it has a disk-like lower stage rotating body 73 (second rotating body). The upper stage rotating body 72 and the lower stage rotating body 73 are formed to have the same diameter and thickness dimension, and rotate around a common rotation axis O in a stacked state. The upper stage rotating body 72 and the lower stage rotating body 73 are arranged slightly inclined so as to be lowered toward the front side.

  FIG. 7 is a perspective view of the upper stage rotating body 72 and the lower stage rotating body 73. The upper rotator 72 is formed with a plurality of (five equally spaced in this example) notches 72a, 72b, 72c, 72d, 72e (first notches) at predetermined intervals in the circumferential direction. The width in the circumferential direction of the not-cut portion between the cutout portion is set to be approximately the same as the width of one opening in the circumferential direction of the cutout portion. Accordingly, the cutout portions and the portions that are not cut out are alternately arranged at equal intervals (equal angular intervals). These notches 72a to 72e have a depth that can accommodate half of one ball. The lower rotator 73 is formed with a plurality (five in this example) of notches 73a, 73b, 73c, 73d, 73e (second notches) in the circumferential direction. Of the cutout portions of the lower rotating body 73, the cutout portions 73b, 73c, 73d, 73e are formed at the same intervals as the cutout portions 72b, 72c, 72d, 72e of the upper rotating body except for one cutout portion 73a. Yes. Then, one notch 73a of the lower rotating body 73 is formed apart from 73e and close to 73b (see FIG. 7b). The depths of the notches 73a to 74e of the lower stage rotating body 73 are the same as the depth dimensions of the notched parts 72a to 72e of the upper stage rotating body 72, and have a depth that can accommodate half of one ball.

  The upper rotating body 72 and the lower rotating body 73 are accommodated in the surrounding wall 71 so as to be stacked in two upper and lower stages. A ball receiving port 74 is formed in the surrounding wall 71 so as to face the central valley portion 63 a of the stage surface 63. A ball is received from the receiving port 74 into the sorting device 70. In the surrounding wall 71, ball discharge ports are formed in a plurality of directions (two directions in this example) at positions separated from the receiving port 74. In this example, a first notch 75 having a predetermined depth is formed in the surrounding wall 71 from the upper end thereof in the direction of 120 degrees with the receiving port 74 as a reference position, and also in the direction of 240 degrees, A second cutout 76 is formed that opens upward leaving the bottom. The depth of the first cutout 75 is substantially the same as the thickness dimension of the upper rotating body 72. In other words, the height of the surrounding wall 71 excluding the notch 75 at that location is the thickness dimension of the lower rotating body 73. I try to be the same. Further, the second cutout portion 76 is cut out by the same dimension as the thickness dimension in which the upper stage rotating body 72 and the lower stage rotating body 73 are stacked in two stages.

  In this example, the first cutout portion 75 forms a loss discharge port, and the second cutout portion 76 forms a contact discharge port. The start winning port 8 is disposed below the second cutout portion 76 (winning discharge port). That is, the hitting outlet 76 is more than the probability that a ball that is launched from the ball launching device 44 of the pachinko gaming machine 1 and does not pass through the sorting device 70 wins the start winning port 8. It is provided at a position where the probability that the ball that has passed 76 will win the start winning opening 8 is higher. Normally, not all balls that do not pass through the distribution device 70 flow down toward the start winning port 8 but also flow down around the corner of the game board 3 that is far from the direction toward the starting winning port 8. is there. However, as can be understood from FIG. 1 and the like, almost all balls that have passed through the hitting outlet 76 of the sorting apparatus 70 proceed toward the start winning opening 8 and win the starting winning opening 8 with a considerably high probability. It becomes.

  Further, in the present embodiment, the relative positional relationship in the rotational direction between the upper stage rotating body 72 and the lower stage rotating body 73 is displaced according to the gaming state. FIG. 8 is a diagram showing the positional relationship between the upper stage rotating body 72 and the lower stage rotating body 73 in the normal state, and FIG. 9 is a diagram showing the upper stage rotating body 72 and the lower stage rotation in the probability variation state and in the short time state (also referred to as a special state). It is a figure which shows the positional relationship with the body 73. FIG. In the cutout portions 72a to 72e of the upper rotating body 72 and the cutout portions 73e to 73e of the lower rotating body 73, only the cutout portion 72a and the cutout portion 73a (only one place) are aligned vertically (first position: FIG. 8). Reference) and a state (second position: see FIG. 9) in which the notches 72b to 72e and the notches 73b to 73e coincide at a plurality of places (four places in this example).

  In this example, when the upper and lower cutouts are aligned vertically, balls are received by these cutouts to form a contact receiving part (W), and the upper and lower cutouts are not aligned. Sometimes, the ball is received only by the cutout portion of the upper rotating body 72 to form a miss receiving portion. The hit receiving part forms a size (depth) that can accommodate one ball by overlapping and matching the notch parts. On the other hand, the lose receiving part has a form in which the upper half of the ball protrudes from the upper surface of the upper rotating body 72 by holding the ball only by the notch of the upper rotating body 72. As shown in FIG. 8, in the normal state, the hit receiving part is only one place (W1) formed by 72a and 73a, while in the special state, the hit receiving part is 72b. And 73b, 72c and 73c, 72d and 73d, 72e and 73e, a total of four locations (W1 to W4).

  FIG. 10 is a diagram illustrating a sorting operation of the sorting apparatus 70 in the normal state. The upper stage rotating body 72 and the lower stage rotating body 73 are united at a constant speed, and in this example, the upper stage rotating body 72 and the lower stage rotating body 73 rotate in the clockwise direction (f) as viewed from the upper surface around the rotation axis O. The balls received in the hit receiving part or the loss receiving part should not fall outside while being held in the respective receiving parts even when the upper rotating body 72 and the lower rotating body 73 are rotated by the enclosure wall 71. ing. The ball received in the loss receiving portion 72d is rotated by the upper and lower rotating bodies 72 and 73 integrally, and when the ball is rotated at an angle of 120 degrees by the rotation, the first cutout portion (the loss discharge port). It rolls from 75 and falls out of the sorting device 70. On the other hand, the ball received in the contact receiving portion W1 is not blocked from the first cutout portion 75 by being blocked by the surrounding wall 71 when the upper and lower rotating bodies 72, 73 are rotated at an angle of 120 degrees by the rotation. Furthermore, when it rotates and it becomes an angle attitude | position of 240 degree | times, it rolls from the 2nd notch part (hit discharge port) 76, and falls out of the sorting apparatus 70. FIG. The start winning port 8 is disposed below the hit discharge port 76, and it can be said that a ball falling from the hit discharge port 76 easily enters the start winning port 8.

  Therefore, in the normal state, the ball is guided above the start winning opening 8 because only one quantity of the hitting receiving portion is formed among the five cutout portions of the upper rotating body 72, and The induction probability is 1/5. In the same way of thinking, in the special state, the number of hitting receiving portions formed among the five notches of the upper rotating body 72 (and the lower rotating body 73) is four, so the probability of guiding to the start winning opening 8 Becomes 4/5.

  Next, position displacement means 80 (position displacement mechanism) for displacing the relative positional relationship between the upper stage rotating body 72 and the lower stage rotating body 73 in the rotation direction will be described. FIG. 11 is a diagram for explaining the position displacement means. First, drive control of the upper rotating body 72 and the lower rotating body 73 will be described. An upper stage driving shaft 81 (with the axis line O) is connected to the upper stage rotating body 72, and an upper stage driving gear 82 is fixed to the other end of the upper stage driving shaft 81. The lower stage rotating body 73 has a common axis O, and a lower stage driving shaft 83 is concentrically connected to the outer side of the upper stage driving shaft 81, and a lower stage driving gear 84 is fixed to the other end of the lower stage driving shaft 83. Has been.

  The upper drive gear 82 and the lower drive gear 84 are configured to be independently driven by a drive motor 86 via a reduction gear 85. In this example, the drive motor switching solenoid 36 is operated by using one drive motor 86, and the position of the drive motor 86 is displaced up and down between the h position and the i position as shown in FIG. I try to let them. When the drive motor switching solenoid 36 is not in operation, the drive motor 86 and the upper drive gear 82 are connected via the reduction gear 85 at the h position. At this time, the reduction gear 85 can be separated from the upper drive gear 82, that is, the gear separation solenoid 35 is operated to rotate the reduction gear 85 between the j position and the k position as shown in FIG. It is designed to be displaced dynamically. When the gear separation solenoid 35 is not in operation, the reduction gear 85 and the upper drive gear 82 are in mesh with each other at the j position. When the gear separation solenoid 35 is activated by a control signal from the CPU 22, the reduction gear 85 is displaced from the j position to the k position, and the reduction gear 85 is separated from the upper drive gear 82. Next, when the drive motor switching solenoid 36 is actuated by a control signal from the CPU 22, the drive motor 86 is displaced from the h position to the i position, and the drive motor 86 is moved to a position facing the lower drive gear 84. Thereafter, the gear separation solenoid 35 is deactivated, whereby the reduction gear 85 returns from the k position to the j position, and the drive motor 86 and the lower drive gear 84 are connected via the reduction gear 85. .

  In the present embodiment, a guide groove 87 having a predetermined angular width is formed on the upper surface of the lower rotating body 73, and a protrusion 88 that slidably engages with the guide groove 87 on the lower surface of the guide upper rotating body 72. Is formed. FIG. 12 is a view showing the guide groove portion 87 of the lower stage rotating body 73. As shown in FIG. 12, a guide groove portion 87 is formed with a predetermined angular width (in this example, an angular width of 36 degrees) spaced apart from the rotation axis O of the lower rotating body 73 by a predetermined distance radially outward. This angular width is determined by the degree of displacement of the relative positional relationship between the upper rotating body 72 and the lower rotating body 73 in the rotational direction.

  In this example, five cutout portions 72a to 72e of the upper stage rotating body 72 are formed in the circumferential direction, and the cutout portions and the portions that are not cutout are alternately arranged at equal intervals. The angular width (36 degrees) is equivalent to the angular width of the opening in the circumferential direction. Of the cutout portions of the lower rotating body 73, the cutout portions 73b, 73c, 73d, 73e are formed at the same intervals as the cutout portions 72b, 72c, 72d, 72e of the upper rotating body, and one cutout portion 73a is formed. , 73e and close to 73b. Accordingly, when the angle is shifted by 36 degrees, the position is shifted in the rotation direction by one notch, the notch 73a of the lower rotating body 73 is aligned with the notch 72a of the upper rotating body 72, and the upper rotating body 72 is aligned. The cutout portions 73b to 73e of the lower rotator 73 are located in a portion where the upper rotator 73 is not cut (see FIG. 8B), or the cutout portion 73a of the lower rotator 73 is not placed in the portion where the upper rotator 72 is not cut. And the notches 73b to 73e of the lower rotating body 73 coincide with the notches 72b to 72e of the upper rotating body 72 (see FIG. 9B).

  As described above, the upper stage rotating body 72 and the lower stage rotating body 73 can be displaced relative to each other in the rotational direction by the angular width (36 degrees), and the drive motor 86 is driven, and the upper stage drive gear. When 82 is driven clockwise through the reduction gear 85 as viewed from above (f direction), the protrusion 88 of the upper rotating body 72 slides and engages with one end 87a of the guide groove 87 of the lower rotating body 73. The upper rotator 72 is the main drive, the lower rotator 73 is the follower, and the lower rotator 73 is rotated together to rotate. By rotating the upper stage driving gear 82 at a constant speed, the upper stage rotating body 72 and the lower stage rotating body 73 are integrated and rotated at a constant speed. This is the rotation with the relative position at the first position (in the normal state), and the contact receiving part is in only one position (W1) (see FIG. 8).

  On the other hand, when the lower stage driving gear 84 is driven, the upper stage rotating body 72 does not rotate for a while after the lower stage rotating body 73 starts to rotate, and the projecting portion of the upper stage rotating body 72 when the lower stage rotating body 73 rotates 36 degrees. 88 slides and engages with the other end 87b of the guide groove 87 of the lower rotating body 73, and the lower rotating body 73 becomes the main drive and the upper rotating body 72 becomes the driven at a position shifted by 36 degrees from the normal state. Then, the upper rotating body 72 rotates together with the upper rotating body 72. This is rotation with the relative position at the second position (in the special state), and the hit receiving part is in four positions (W1 to W4) (see FIG. 9). In this way, the guide groove portion 87, the projection 88, and the driving means (specifically, the driving motor 86, the upper driving gear 82, and the lower driving gear 84) of the upper stage rotating body 72 or the lower stage rotating body 73 are position displacement means 80. Function as. As a result, the drive motor 86, which is the driving means for the upper and lower rotating bodies 72, 73, can also be used as a device for displacing the relative positions of the upper rotating body 72 and the lower rotating body 73 in the rotational direction, and the configuration can be simplified. Further, the drive means can also be constituted by one drive motor 86.

  Next, a specific control procedure will be described with reference to a flowchart. The motor control processing program 52 stored in the ROM 23 will be described with reference to the flowchart shown in FIG. The control program 51 stored in the ROM 23 is responsible for overall control of the pachinko gaming machine 1, and after the power to the pachinko gaming machine 1 is turned on, initialization processing such as interrupt mode setting and RAM check, and initialization are performed. Since it is a well-known content for executing a winning detection process, a jackpot lottery process, a symbol variation process, a jackpot process, etc. at the start winning opening 8 after the process is finished, the description is omitted.

  In the present embodiment, a jackpot lottery is performed in accordance with winning at the start winning opening. The jackpot lottery will be described. When a winning of a ball is detected by the starting winning detector 32 attached to the starting winning opening 8, a winning detection signal is transmitted to the CPU 22. Whether or not the CPU 22 obtains a random value (counter value) from the jackpot determination counter according to the timing when the winning detection signal from the start winning detector 32 is input to the CPU 22, and whether or not the random number value matches the jackpot random number. The jackpot lottery is performed by judging. When the random number value is a jackpot random number in the lottery process, the jackpot condition is satisfied. The CPU 22 functions as a success / failure lottery means.

  The CPU 22 receives the result of the jackpot lottery process and determines a symbol to be derived and displayed on the special symbol display unit 7 of the accessory device 6. A display control signal based on the determination is output from the CPU 22 to the display control board 26. The jackpot lottery result is temporarily stored in the reserved ball storage area allocated to the RAM 24. The CPU 22 confirms whether or not a new symbol variation operation can be performed in the special symbol display unit 7 of the accessory device 6, and then reads the lottery result and starts the symbol variation operation. When the symbol variation operation related to the previous jackpot lottery process is performed, lottery data including the result of the jackpot lottery process is stored in the reserved ball storage area with an upper limit of four.

  There is a winning at the start winning opening 8, and a jackpot lottery is executed, and according to the lottery result, the special symbol display unit 7 displays the symbols in a variable manner and then stops the display. When the special symbol display unit 7 stops displaying a predetermined jackpot symbol, a jackpot occurs. As a jackpot game, one opening and closing of the big winning opening 9 is one round, and the opening operation of the big winning opening 9 is repeatedly executed until a predetermined round (for example, 15 rounds) is reached. While the jackpot game is being executed, the symbol variation in the special symbol display unit 7 is not performed. The CPU 22 functions as a jackpot generating means. And when the jackpot symbol which the special symbol display part 7 shows is a specific jackpot symbol, the probability variation state which raised the jackpot lottery probability after the jackpot end is generated. There may be a case in which a short time state is generated at the same time by shortening the one time variable display time of the special symbol display unit 7. The CPU 22 functions as a special state generating means for generating a probability change state and a short time state (special state) after the end of the jackpot.

  The CPU 22 outputs the gaming state transition signal 1 when the jackpot is finished and the player enters the probability changing state (or the short time state). In S1 of FIG. 13, it is determined whether or not the gaming state transition signal 1 is received, and when the gaming state transition signal 1 is received, the gear separation solenoid 35 is turned ON (S2). The reduction gear 85 is separated from the upper drive gear 82. After a predetermined time has elapsed (for example, 0.1 second), the drive motor switching solenoid 36 is turned on (S3). The drive motor 86 is moved to a position facing the lower drive gear 84. After a predetermined time has elapsed (for example, 0.3 seconds), the gear separating solenoid 35 is turned off (S4). The reduction gear 85 is connected to the lower drive gear 84. When the drive motor 86 is driven, the lower stage rotating body 73 rotates. The lower rotator 73 is the main drive, the upper rotator 72 is the follower, and the relative position between the upper rotator 72 and the lower rotator 73 is the second position, that is, there are four contact receiving portions (W1 to W4). Rotates at a constant speed in the state. In the probability variation state, the ratio of guiding the ball to the start winning opening 8 is four times that in the normal state (the induction probability is 1/5 to 4/5).

  The probability variation state ends when the probability variation state termination condition is satisfied, such as the occurrence of the next jackpot. The CPU 22 outputs the gaming state transition signal 2 when the probability changing state (or the short time state) ends. If the gaming state transition signal 1 is not received in S1, it is determined whether or not the gaming state transition signal 2 has been received (S5). If the gaming state transition signal 2 is not received, the process returns to S1, while if the gaming state transition signal 2 is received, the gear separation solenoid 35 is turned ON (S6). The reduction gear 85 is separated from the lower drive gear 84. After a lapse of a predetermined time (for example, 0.1 second), the drive motor switching solenoid 36 is turned off (S7). The drive motor 86 is returned to a position facing the upper drive gear 82. After a predetermined time has elapsed (for example, 0.3 seconds), the gear separating solenoid 35 is turned off (S8). The reduction gear 85 is connected to the upper drive gear 82. When the drive motor 86 is driven, the upper rotating body 72 rotates. The upper stage rotating body 72 is the main drive, the lower stage rotating body 73 is the follower, and the relative position between the upper stage rotating body 72 and the lower stage rotating body 73 is in the first position, that is, the contact receiving portion is in one place (W1). Rotates at a constant speed. In the normal state, the induction probability of guiding the ball to the start winning opening 8 becomes 1/5.

  Thus, the upper stage rotating body 72 in which the first notches 72a to 72e are formed at predetermined intervals in the circumferential direction and the lower stage rotating body 73 in which the second notches 73a to 73e are formed in the circumferential direction are vertically moved. Arranged in a stacked state, the upper part rotates between a first position where there is only one contact receiving part where the first notch part and the second notch part coincide with each other and a second position where there are four contact receiving parts The relative position in the rotational direction between the body 72 and the lower rotating body 73 is displaced, and the ratio of guiding the ball toward the start winning opening 8 can be changed by the change in the relative position in the rotational direction. It becomes a sorting device equipped with an unprecedented rotating body, and can provide interest to the player.

  Further, according to the state of the game, for example, in the case of a probability change state (or a short time state), for example, the relative position in the rotational direction of the upper stage rotating body 72 and the lower stage rotating body 73 is displaced from the first position to the second position. By configuring, the winning rate (winning probability) to the start winning port 8 can be made higher than in the normal state. Conventional pachinko machines are usually equipped with an electric tulip that shows a closed state and an open state at the top of the start winning opening, and when the probable state or the short state is advantageous to the player, the opening time of the electric tulip is usually extended. Although the game more advantageous than the state can be performed, if the sorting device 70 provided with the upper and lower rotating bodies 72 and 73 of the present invention is employed, it is possible to enter the starting prize opening without providing an electric tulip. The winning rate can be improved.

Further, the following modifications may be added to the present embodiment.
(1) The driving of the upper drive gear 82 and the lower drive gear 84 is configured using one drive motor 86, but may be configured to be switched and driven using two drive motors.
(2) Although the distribution device 70 is a winning / losing distribution device, the distribution device itself may be a winning device. A winning detector may be provided in the vicinity of the winning discharge port 76 to detect a winning. Alternatively, the start winning port 8 may be arranged directly below the winning discharge port 76 so that a ball falling from the winning discharge port 76 always wins the starting winning port.

(3) The distribution device 70 may be a guidance device to a specific winning opening. For example, the first cutout portion 75 (losing discharge port) can be guided to the first specific winning port, and the second cutout portion 76 (winning discharge port) can be guided to the second specific winning port. .
