The movable iron core 50 of the solenoid 27 is urged downward by a spring 51, and the movable iron core 50 is fixed at both upper and lower ends to a rectangular lifting frame 52 surrounding the solenoid 27. The elevating frame 52 is provided between the mounting base 40 and the mounting plate 48 so as to be able to move up and down, and the elevating frame 52 is integrally formed with an arm 52a projecting into the router hole 31. The arm 52a has a notch formed at the tip thereof, and an engaging pin 54 formed eccentrically at one end of the pivot 35 is engaged with the engaging portion 53. Next, the operation of the above configuration will be described.
Normally, the solenoid 27 is in the demagnetized state, and the lifting frame 52 is urged downward by the spring 51, so that the lifting frame 52 is at the lowered position. Therefore, as shown by the dotted line in FIG. 6, the opening / closing plate 26 is at a closed position rising upward from the pivot 35, and closes the opening 28 from the front side. Therefore, the game ball B falling from above passes through the front side of the opening / closing plate 26 and falls downward. When the game ball B enters the starting gate 14, the symbol display device 13
The symbol of each symbol display section fluctuates for a fixed time. Then, when the stop symbol of each symbol display section of the symbol display device 13 hits the symbol, the solenoid 27 of the specific winning device 15 is excited, and the movable iron core 50 rises against the spring 51. As a result, the lifting frame 52 rises, and the engaging pin 54 that engages with the engaging portion 53 at the tip of the arm 52a is lifted upward, so that the opening / closing plate 26 pivots as shown by a solid line in FIGS. It rotates in the direction of arrow a to the open position around 35. At this time, the opening and closing plate 26
Is restricted by a stopper (not shown) abutting against the mounting base 40. When the open / close plate 26 rotates to the open position, the game ball B falling from above hits the open / close plate 26 and is guided by the open / close plate 26 to the opening 28 side. Go into. At this time, if there are game balls B falling at the left and right central portions of the opening and closing plate 26 as shown in FIG. After hitting 26, as shown in FIG. 3 and FIG. 4, it is received and stopped by the U-shaped stopping portion 38. Therefore, even if the opening / closing plate 26 is opened, the game ball B immediately passes through the specific passage.
The player does not enter 34a, and the player can visually confirm that the game ball B is in the stop state in the stop portion 38. The game ball B which has fallen on both the left and right sides of the opening / closing plate 26
After hitting the opening / closing plate 26 and guided to the opening 28 side, it enters the ball fall passage 42 of the rear case 25 via the left and right passages 34, falls down from the fall hole 44 and is collected. Also, if one game ball B stops at the stop portion 38, then the opening / closing plate 26
The subsequent game ball B falling to the center of the game ball B hits the game ball B stopped at the stop portion 38 or the opening / closing plate 26 and the like, and is then distributed to both sides of the stop portion 38 and both sides of the opening 28. Move to the ball drop passage 42 via the passage 34 of FIG. When the game ball B is in the stop state at the stop portion 38, the subsequent game ball B
If dropped, the opening / closing plate 26 may vibrate up and down. However, since the opening / closing plate 26 has a positioning projection 38a, which regulates and positions the game ball B in the stopping portion 38, the stopped game ball B moves on the opening / closing plate 26 in an unstable manner. Thus, the game ball B once entering the stop portion 38 does not unexpectedly come off the stop portion 38, and the game ball B can be reliably stopped at the stop portion 38. When a predetermined time elapses after the opening and closing plate 26 is opened, the solenoid 27 is demagnetized, and the movable iron core 50 and the lifting frame 52 are lowered by the spring 51, so that the opening and closing plate 26 is turned around the pivot 35 to the closed position. And the opening 28 is closed. And
The stopping portion 38 tilts downward and the game ball B stopped at the stopping portion 38 moves to the first detection switch 18 side through the specific passage 34a while rolling backward, 1 Because it falls down from the hole of the detection switch 18, the first
The detection switch 18 detects the game ball B. When the first detection switch 18 detects the game ball B, if the game ball B is already in any of the winning ports 11, 12, the special winning device 16 is operated next. The game ball B in the ball drop passage 42 falls downward from the drop hole 44, and is detected by the second detection switch 45. Since the stopping portion 38 has a gutter shape and is formed integrally with the opening / closing plate 26 so as to protrude, the stopping portion 38 is attached to the opening / closing plate 26 after the opening / closing plate 26 and the stopping portion 38 are separately formed. As compared with the case, the structures of the opening / closing plate 26 and the stopping portion 38 can be simplified, and the strength of the stopping portion 38 itself also increases. When the stopping portion 38 is formed in a gutter shape, it may be formed in a U-shaped cross section as shown in the first embodiment, or may be formed in a V-shaped cross section, a U-shaped cross section, or the like. A shape having a receiving groove is sufficient. FIGS. 9 and 10 show a second embodiment of the present invention, in which a pair of left and right strip-shaped projections 60 are provided on the opening / closing plate 26 in an inverted C-shape. It is what constituted. The protrusion 60 is protruded to the game ball B is stationary, integrally with the closing plate 26 in the lateral direction with a predetermined gap therebetween. In the case of the second embodiment, the structure of the opening / closing plate 26 and the stopping portion 38 is simplified, and since the space between the pair of left and right projections 60 is open, dust and the like do not accumulate in the stopping portion 38. FIGS. 11 and 12 show a third embodiment of the present invention, in which a pair of left and right pin-shaped projections 61 are provided on the opening / closing plate 26, and the pair of left and right projections 61 constitute the stopping portion 38. FIG. The base of the projection 61 is thicker than the tip. Also in the case of the third embodiment, similarly to the second embodiment, the structures of the opening / closing plate 26 and the stopping portion 38 are simplified, and accumulation of dust and the like in the stopping portion 38 can be prevented.
