As shown in FIG. 7, first, in step (hereinafter referred to as “S”) 1, the CPU 461 executes a determination process for determining whether or not the shelf board member 88 has been moved to the upper end position. Specifically, the CPU 461 calculates the vertical position of the shelf member 88 based on output signals from a potentiometer, an absolute rotary encoder, etc. provided in the drive motor 85, and the shelf member 88 reaches the upper end position. It is determined whether or not it has been moved.
If the shelf board member 88 has not been moved to the upper end position (S1: NO), in S2, the CPU 461 determines that the CPU 461 is based on an output signal from a potentiometer, an absolute type rotary encoder or the like provided in the drive motor 85. The drive motor 85 is rotationally driven to move the shelf board member 88 to the upper end position and stop.
On the other hand, when the shelf board member 88 has moved to the upper end position and stopped (S1: YES), the CPU 461 does not drive the drive motor 85 and stops the shelf board member 88 at the upper end position. maintain.

Subsequently, in S3, the CPU 461 reads a shelf flag from the RAM 463, and executes a determination process for determining whether or not this shelf flag is ON, that is, whether or not this shelf flag is “1”. The shelf flag is initialized at the time of activation, that is, “0” is substituted and stored in the RAM 463.
If the shelf flag read from the RAM 463 is not ON (S3: NO), in S4, the CPU 461 performs a sub-process of “opening / closing member opening / closing drive process” for reciprocating the opening / closing member 77 in the front-rear direction in a predetermined pattern. After executing the process (see FIG. 8), the process ends.
On the other hand, when the shelf flag read from the RAM 463 is ON (S3: YES), in S5, the CPU 461 reciprocates the shelf member 88 in a predetermined pattern in the “reciprocating process of shelf member”. After executing the sub-process (see FIG. 9), the process is terminated.

Next, sub-processing of “opening / closing member opening / closing drive processing” will be described with reference to FIG.
As shown in FIG. 8, first, in S <b> 11, the CPU 461 turns off the inlet solenoid 78, moves the opening / closing member 77 forward by the biasing force of the coil spring 79, and closes the warp inlet 75 with the opening / closing member 77. At the time of start-up, the inlet solenoid 78 is OFF.
In S12, the CPU 41 reads predetermined first pattern data, which is an opening / closing pattern of the warp inlet 75, from the ROM 462, stores the closing time T1 of the warp inlet 75 in the RAM 463, and the closing time T1 elapses. (S12: NO).
As the predetermined first pattern data, the closing time T1 of the warp inlet 75 (for example, about 10 seconds to about 50 seconds, preferably about 25 seconds) and the opening time T2 of the warp inlet 75 (for example, , About 2 seconds to about 10 seconds, and preferably about 5 seconds).

When the closing time T1 of the warp inlet 75 has elapsed (S12: YES), in S13, the CPU 461 turns on the inlet solenoid 78 to move the opening / closing member 77 in the reverse direction, thereby opening the warp inlet 75. . Thereby, the game ball can flow into the warp inlet 75.
In S <b> 14, the CPU 41 reads predetermined first pattern data that is an opening / closing pattern of the warp inlet 75 from the ROM 462, stores the opening time T <b> 2 of the warp inlet 75 in the RAM 463, and opens the warp inlet 75. A determination process for determining whether or not the opening time T2 has elapsed is executed. If the opening time T2 has not elapsed since the warp inlet 75 was opened (S14: NO), in S15, the CPU 461 determines whether or not a game ball has flowed into the warp inlet 75, that is, a detection sensor. A determination process for determining whether or not a game ball detection signal is input from 81 is executed.

If no detection signal of a game ball is input from the detection sensor 81 in S15 (S15: NO), the CPU 461 executes the processes after S14 again.
On the other hand, when a detection signal of a game ball is input from the detection sensor 81 in S15 (S15: YES), in S16, the CPU 461 reads the shelf flag from the RAM 463, turns the shelf flag on, that is, the “1” is substituted into the shelf flag and stored in the RAM 463 again.
Subsequently, in S17, the CPU 461 turns off the inlet solenoid 78 and moves the opening / closing member 77 forward by the biasing force of the coil spring 79. After closing the warp inlet 75 with the opening / closing member 77, the sub-process is terminated. To return to the main flowchart.
On the other hand, when the opening time T2 has elapsed since the warp inlet 75 was opened in S14 (S14: YES), in S18, the CPU 461 reads the shelf flag from the RAM 463 and turns the shelf flag OFF, ie, “0” is substituted into the shelf flag and stored in the RAM 463 again. In S17, the CPU 461 turns off the inlet solenoid 78 and moves the opening / closing member 77 forward by the biasing force of the coil spring 79. After closing the warp inlet 75 with the opening / closing member 77, the sub-process is terminated. Return to the main flowchart.

Next, the sub-process of “the reciprocating process of the shelf board member” will be described with reference to FIGS. 9 to 14.
As shown in FIG. 9, first, in S <b> 21, the CPU 461 reads predetermined second pattern data that is a reciprocating movement pattern of the shelf board member 88 from the ROM 462, and is a waiting time at the upper end of the shelf board member 88. The upper stop time T3 is stored in the RAM 463 and waits for the upper stop time T3 to elapse (S21: NO).
For example, as shown in FIGS. 10 and 11, the shelf board member 88 is stopped for the upper stop time T3 at the upper end position, so that the game ball P that has flowed out from the warp passage 76 to the upper surface portion of the shelf board member 88. Rolls on the shelf member 88 in the left-right direction.
As the predetermined second pattern data, an upper stop time T3 (for example, about 2 seconds to 5 seconds, preferably about 3 seconds) indicating a waiting time at the upper end position of the shelf board member 88, and The rotational speed V1 of the drive motor 85 that moves the shelf board member 88 to the lower end position (for example, the rotational speed that moves the shelf board member 88 from the upper end position to the lower end position for about 4 to 8 seconds, preferably about 5 seconds. ), A lower stop time T4 indicating the waiting time at the lower end position of the shelf board member 88 (for example, about 1 to 5 seconds, preferably about 2 seconds), and the shelf board member 88 at the upper end position. The rotational speed V2 of the drive motor 85 that is moved up to (for example, the rotational speed at which the shelf board member 88 is moved from the lower end position to the upper end position for about 4 to 8 seconds, preferably about 5 seconds) is stored in the ROM 462 in advance. It is remembered.

When the upper stop time T3 of the shelf board member 88 has elapsed (S21: YES), in S22, the CPU 461 reads the predetermined second pattern data from the ROM 462 again, and moves the shelf board member 88 to the lower end position. The rotational speed V1 of the drive motor 85 to be moved is stored in the RAM 463, and the drive motor 85 is rotationally driven in a predetermined direction at the rotational speed V1 to start the downward movement of the shelf board member 88.
In S23, the CPU 461 waits for the shelf board member 88 to move to the lower end position based on output signals from a potentiometer and an absolute rotary encoder provided in the drive motor 85 (S23: NO).
On the other hand, when the shelf board member 88 has moved to the lower end position (S23: YES), in S24, the CPU 461 turns off the drive motor 85 and stops the shelf board member 88 at the lower end position.

Subsequently, in S25, the CPU 461 reads predetermined second pattern data from the ROM 462 again, stores the lower stop time T4 that is a waiting time at the lower end of the shelf board member 88 in the RAM 463, and the lower stop time T4 is Wait for the time to elapse (S25: NO). That is, the CPU 461 waits for the game ball P rolling on the shelf member 88 in the left-right direction to randomly flow into any one of the through holes 88A to 88C and drop downward. .
For example, as shown in FIGS. 12 to 14, the shelf board member 88 stops at the lower end position for the lower stop time T <b> 4, and the through holes 88 </ b> A to 88 </ b> C in the upper surface portion of the shelf board member 88 are arranged. Since the upper surface portion of the front side end edge portion is the lowest and substantially horizontal, the game ball P on the shelf board member 88 rolls in the left-right direction and the front side on which the through holes 88A to 88C are arranged. It rolls in the direction of the upper surface of the side edge, flows into the through-hole 88A located at the center in the left-right direction, and falls in the direction of the start port 31.

In addition, when the lower stop time T4 of the shelf board member 88 has elapsed (S25: YES), in S26, the CPU 461 reads predetermined second pattern data from the ROM 462 again, and moves the shelf board member 88 to the upper end position. The rotational speed V2 of the drive motor 85 to be moved is stored in the RAM 463, and the drive motor 85 is rotationally driven in the direction opposite to the predetermined direction at the rotational speed V2 to start the upward movement of the shelf board member 88. .
In S27, the CPU 461 waits for the shelf board member 88 to move to the upper end position based on output signals from a potentiometer, an absolute rotary encoder, and the like provided in the drive motor 85 (S27: NO).
On the other hand, when the shelf board member 88 has moved to the upper end position (S27: YES), in S28, the CPU 461 turns off the drive motor 85 and stops the shelf board member 88 at the upper end position.
Subsequently, in S29, the CPU 461 reads the shelf flag from the RAM 463, turns off the shelf flag, that is, substitutes “0” for the shelf flag, stores it again in the RAM 463, and ends the sub-process. To return to the main flowchart.

  Here, the liquid crystal display 19 functions as a display device body. Further, each swing lever 82, the rotation shaft 83, each gear 84, 86, and the drive motor 85 constitute a moving means. The opening / closing member 77, the inlet solenoid 78, and the coil spring 79 constitute an opening / closing member. The through hole 88A functions as a discharge portion. The detection sensor 81 functions as a detection unit. Further, the CPU 461, the ROM 462, and the RAM 463 constitute a first control unit and a second control unit.

Therefore, in the pachinko machine 1 according to the present embodiment, the game ball that has flowed into the warp inlet 75 of the special symbol display device 18 flows out to the upper surface of the shelf board member 88 that can be reciprocated in the vertical direction. It is possible to enjoy the rolling of the game ball on the shelf member 88 that moves in the side direction, and it is possible to strongly attract the player's interest in the game ball that has flowed into the warp inlet 75 and to increase the interest. Further, when the shelf board member 88 moves downward in the recess 72, game balls riding on the upper surface portion randomly flow into any of the through holes 88 </ b> A to 88 </ b> C of the shelf board member 88. If the liquid falls to the lower side and flows into the through-hole 88A, the probability of winning the start opening 31 provided on the lower side of the special symbol display device 18 is high. It is possible to increase the player's expectation for the start of fluctuations, and to further attract the player's interest and increase interest. Further, it is possible to surely enjoy the rolling of the game ball on the shelf board member 88 moving in the downward direction, attracting the player's interest in the game ball flowing into the warp inlet 75 more strongly, and increasing the interest. It becomes possible.
When the detection sensor 81 detects the passage of the game ball, the warp inlet 75 is closed by the opening / closing member 77, so that one game ball flows into the warp inlet 75 and flows out onto the shelf member 88. The rolling speed of the game ball on the shelf member 88 can be maintained, and the player can roll the game ball on the shelf member 88 that moves downward. You can enjoy more.
In addition, since the shelf member 88 is moved to the upper end position and stopped at normal times, the player can easily see the changing symbols displayed on the liquid crystal display 19 and the game ball on the shelf member 88. Is outflowing and rolling, the shelf board member 88 is moved in the downward direction so that the game ball can drop in the direction of the start port 31, so that a novel flow-down mode of the game ball can be achieved. Can be provided.
In addition, since the lower side wall 74 of the recess 72 of the special symbol display device 18 is provided so as to be inclined outward and downward, the game ball rolling and falling in the recess 72 is reliably transferred to the game area 11. The shelf plate member 88 can be reliably moved to the lower end position.
Further, since a transparent protective cover 90 is disposed on the front side of the liquid crystal display 19, the shelf plate member 88 and a game ball rolling on the shelf plate member 88 collide with the liquid crystal display 19. Can be prevented, and the liquid crystal display 19 and the like can be prevented from being damaged or broken, and the reliability of the special symbol display device 18 can be improved.

  In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention. For example, the following may be used.

  (A) In the above embodiment, the closing time T1 of the warp inlet 75 (for example, about 10 seconds to about 50 seconds, preferably about 25 seconds) is the opening time T2 of the warp inlet 75 (for example, about 2 2 to about 10 seconds, and preferably about 5 seconds). However, the closing time T1 and the opening time T2 may be substantially the same. For example, the closing time T1 and the opening time T2 may be approximately the same time between about 3 seconds and 5 seconds. Thereby, since the probability that a game ball will flow into the warp inlet 75 is increased, the interest of the player can be further increased.

  (B) In the above embodiment, the shelf member 88 is set to open the warp inlet 75 after the closing time T1 (for example, 25 seconds) has elapsed after reciprocating in the vertical direction. After the shelf member 88 is reciprocated in the up and down direction, only the closing time until the warp inlet 75 is first opened is shorter than the closing time T1 (for example, about 1 to 5 seconds, preferably 3 seconds). It may be set so as to be. Thereby, since the possibility that the game ball flows into the warp inlet 75 and the shelf board member 88 continuously reciprocates increases, it is possible to further increase the interest of the player.
