The configuration in which the overflowing game balls flow down to the overflow ball guide path 33 is not limited to the above configuration.

The overflow ball guide path 33 has an outlet at the lower end communicating with the lower tray 7 to allow the overflow ball to overflow to the lower tray 7.
In the present embodiment, the upper flow path 33a formed in the rear mechanism panel 15 and the spherical flow path forming member 34 attached to the lower rear surface of the front frame 2 located below the frame board 12. And an overflow detector (not shown) is provided in the middle of the upper flow path 33a.

The spherical channel forming member 34 is a plastic box-shaped member. As shown in FIGS. 4 and 5, a spherical inlet 41 is provided on the upper surface behind the flange portion 40 attached to the back surface of the front frame 2. The ball drop chamber 43 which is opened and the floor section 42 is inclined downward in one of the left and right directions and the game ball from the ball discharge path 23 side is dropped from the ball entrance 41 onto the floor section 42 to receive the ball, The lower end of the floor 42 communicates with the lower end of the floor 42 so that the floor 44

Can be easily and reliably adjusted to the predetermined position. Then, in this state, if a screw is fixed to the fixing hole 50 or a staple is driven in,
The front frame 2 can be easily fixed at a predetermined position on the back surface.

The ball falling chamber 43 has a ball inlet 4 opened on the upper surface.
Reference numeral 1 denotes a chamber that communicates with the upper flow path 33a of the back mechanism panel 15, and a surface of the floor portion 42 located at the lower end of the slope is open, and this open portion communicates with the charge removal chamber 46. Therefore, the overflowing sphere that has flowed down in the upper flow path 33a is:
The ball flows into the ball falling chamber 43 from the ball inlet 41 and falls on the floor 42 to convert the flowing direction toward the lower end of the inclined surface.
Due to the downward inclination of 2, it flows down toward the charge removal chamber 46. Then, the overflowing ball that has flowed down vigorously from the upper flow path 33a is weakened when the flowing down direction is changed in the ball falling chamber 43.

In the charge removing chamber 46, the floor portion 44 is inclined downward toward the front and communicates with the lower tray 7 at the ball outlet 53 at the lower end of the inclination. In the present embodiment, the lower end of the rear end standing wall which is the upper end of the inclination is provided. In this portion, a concave portion 54 recessed behind the rear end rising wall of the ball falling chamber 43 is formed, and a step portion 55 is formed in the middle of the inclination of the floor portion 44, and the step rising of the step portion 55 is formed. A locking hole 56 is formed in the surface, and a floor projection 60 that protrudes from the flange portion 40 is formed at the inclined lower end of the floor portion 44, and the floor portion 44 has a shape corresponding to the upper surface shape of the floor portion 44. The conductive plate 45 is laid. The concave portion 54 is
The vertical dimension is set smaller than the diameter of the game ball so that the game ball does not enter inside. On the ceiling surface located above the floor portion 44 on the downstream side of the step portion 55, a communication port 62 is formed to communicate with the outlet of the ball removal channel 61 formed in the frame board 12. Therefore, when the ball removing operation section 63 of the upper tray 6 is operated, the upper tray 6
The game balls inside flow down the ball removal channel 61 of the frame board 12, flow down from the communication port 62 into the charge removal chamber 46, and are finally discharged into the lower tray 7.

The conductive plate 45 is a plate material such as a stainless steel plate having conductivity. In this embodiment, as shown in FIG.
In addition to forming the step bent portion 64 in accordance with the step of the floor portion 44, the conductive upright portion 65 having a height at which the inclined upper end enters the concave portion 54 is bent and formed into a substantially inverted L-shape. A fastening hole 66 is formed substantially at the center of the upright portion 65, and a locking claw 70 is formed by cutting a part of a side edge of the step bent portion 64 so as to project rearward. ,
The tip hooking portion 71 hooked on the floor protrusion 60 is bent so as to be folded downward.

In order to attach the conductive plate 45 having such a configuration to the floor portion 44 of the charge removing chamber 46, the conductive plate 45 is inserted from the ball outlet 53 side, and the conductive standing portion 65 is stored in the concave portion 54. The front hook portion 71 is hooked on the floor protrusion 60, and the locking claw 70 is locked in the locking hole 56. In this state, a metal screw as a conductive fastening member is inserted into the fastening hole 66 of the conductive standing portion 65. When the nut 73 is screwed into the metal screw 72 protruding to the outside through the rear end erecting wall through the rear end 72 and tightened, the leading end of the conductive plate 45 is hooked on the floor projection 60, so that it is fixed. Can be. Moreover, the conductive plate 45
Is inserted from the ball outlet 53 side, the locking claw 70 is
Is locked in the locking hole 56 of the stepped portion 55, so that there is no floating in the middle of the inclination. When the conductive plate 45 is attached, the nut 73 is attached to the metal screw 72 protruding outside.
When screwing together, one end of the ground wire 74 is connected, and the other end of the ground wire 74 is connected to the game board storage frame 10 to make the conductive plate 45 and the game board storage frame 10 conductive.

When the overflowing ball flows down in the charge removing chamber 46 having such a configuration, the head of the metal screw 72 is located in the concave portion 54 which is vertically recessed and smaller than the diameter of the game ball. Therefore, the overflowing ball that has flowed down from the ball falling chamber 43 is unlikely to hit the head of the metal screw 72, and the falling force of the ball is also weakened by the action of the ball falling chamber 43 when hitting. The head can be prevented from being worn or damaged. Therefore, even when the conductive plate 45 is replaced, the metal screw 72 can be easily removed.

The overflowing ball that has flowed down from the ball falling chamber 43 flows down while rolling down the floor portion 44 toward the ball outlet 53 by inclining, and at this time, the static electricity charged on the ball is discharged to the conductive plate 45. Is released to the game board storage frame 10 through the ground wire 74, and is discharged in the air in the game board storage frame 10. Therefore, the conductive plate 4 of the charge removal chamber 46
The overflowing sphere that has flowed down onto the lower tray 7 and has been discharged to the lower receiving tray 7 is weakened in electric charge, so that electric shock of the player can be prevented. Further, when the ball flows down on the conductive plate 45, if the flowing force is strong, the ball may be charged again by friction between the balls, friction with the floor portion, or friction with the side wall surface. Since the downward force is weakened by the downward force reduction effect of the ball falling chamber 43, the charge of the balls discharged to the lower tray 7 can be reliably removed.

Then, a metal plate is laid on the bottom of the lower receiving tray 7, or the lower receiving tray 7 itself is made of conductive plastic, so that at least the bottom has conductivity.
The conductive upper end portion is connected to the conductive plate 4 of the charge removing chamber 46.
5, the static electricity of the game balls in the lower saucer 7 can be released from the conductive plate 45 to the game board storage frame 10 via the ground wire 74.
The electric shock of the player can be more reliably prevented.

In the above-described embodiment, the ball falling chamber 43 is formed beside the charge removing chamber 46, and the downward force of the overflowing ball flowing down almost vertically is attenuated by the ball falling chamber 43. Even if the device is directly dropped into the charge removing chamber 46 without providing the same, the conductive upright portion 65 of the conductive plate 45 is housed in the recess 54 and fastened with the metal screw 72, so that the metal screw 72 It is possible to prevent the overflowing sphere that has flowed down from directly abutting, and to protect the head of the metal screw 72. In the above-described embodiment, the metal screw 72 is used as the conductive fastening material. However, the present invention is not limited to this.

Further, the present invention is not limited to a pachinko machine, but may be an arrangement ball type game machine or a sparrow ball game machine.
