Are provided in a substantially V shape in side view. Stop 38
Is a pair of partition plates 33 in the opening 28 when the opening / closing plate 26 opens and closes.
The gap is set so that the game ball B does not enter the specific passage 34a from between the partition plates 33 even when the open / close plate 26 is in the open state. The opening / closing plate 26 is formed with two projecting portions 38a for positioning corresponding to the stopping portion 38 so as to protrude slightly therefrom.
The game ball B stopped on the upper side is regulated so as not to move on the side of the opening / closing plate 26 in an unstable manner. The rear case 25 includes a mounting base 40 attached to the back side of the game board 4 by screws 39, and a concave wall portion 41 integrally formed with the mounting base 40. A ball drop passage 42 communicates with the opening 28 on the part case 24 side. At the center of the concave wall portion 41, the specific passage 34
A first detection switch 18 having a hole is detachably mounted via a support portion 43 so as to detect a game ball B that has passed through a and entered the ball fall passage 42. The lower side of the ball drop passage 42 is narrowed narrowly from the left and right sides. A drop hole 44 and a second detection switch 45 with a hole for detecting a game ball B falling from the drop hole 44 are provided at the center of the lower end. ing. The concave wall portion 41 is provided with triangular blocking ribs 46 on both the left and right sides of the supporting portion 43. The blocking ribs 46 reinforce the supporting portion 43 and play the game balls passing through the passages 34 on both sides. B is prevented from entering the first detection switch 18 side. Each partition plate 33 is also provided with a protruding portion 47 protruding above the blocking rib 46. As shown in FIGS. 3 to 5, the solenoid 27 is vertically arranged on the side of the concave wall portion 41, and
48, it is fixed to the mounting base 40 via the boss 49. 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 elevating frame 52 surrounding the solenoid 27. The lifting frame 52 includes a mounting base 40 and a mounting plate.
The lifting frame 52 is provided with an arm 52a projecting into the router hole 31 integrally therewith. The arm 52a has a notch formed at the tip thereof,
An engaging pin 54 eccentrically formed 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. For this reason, the opening / closing plate 26 is in a closed position rising upward from the pivot 35 as shown by a dotted line in FIG. 6, 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 of each symbol display section of the symbol display device 13 fluctuates for a predetermined time. When the stop symbol of each symbol display section of the symbol display device 13 becomes a hit 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 the solid line in FIGS.
It rotates in the direction of arrow a to the open position around 35. At this time, the opening / closing plate 26 is regulated by a stopper (not shown) in contact with 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 / closing plate 26, as shown in FIG. After hitting 26, as shown in FIGS. 3 and 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 that has fallen to 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 through the left and right passages 34, falls downward from the fall hole 44, and is collected. Also, if one game ball B stops at the stopping 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 in the stopped state at the stop portion 38, or the open / close plate 26, etc., and is then distributed to both sides of the stop portion 38, and both sides of the opening 28. Move to the ball fall passage 42 through the passage 34 of FIG. When the game ball B is in a stationary state at the stationary portion 38,
If the subsequent game ball B falls on the open / close plate 26, the open / close plate 26 may vibrate up and down. However, the opening / closing plate 26 has a projection 38a for positioning.
The game ball B stopped on the opening / closing plate 26 moves unstably, and once enters the stop portion 38, the stopped game ball B comes off the stop portion 38 unexpectedly. That is, 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 one of the winning openings 11 and 12, the special winning device 16 is operated next. The game ball B in the ball drop passage 42 falls down from the drop hole 44 and is detected by the second detection switch 45. The stop 38 is gutter-shaped,
Since it is formed integrally with the opening / closing plate 26, after forming the opening / closing plate 26 and the stopping portion 38 separately, compared with the case where the stopping portion 38 is attached to the opening / closing plate 26, the opening / closing plate 26 and the stopping portion 38 The structure can be simplified, and the strength of the retaining portion 38 itself can be increased. Embodiments of the present invention will be described below in detail with reference to the drawings.
I do. In the present invention, instead of the gutter-shaped stopping portion 38 of the comparative example, an opening is provided.
