A shaft support 110 for supporting the mechanism plate 70 so that it can be opened and closed is fixed to one end of the upper component part and the intermediate component part of the mechanism plate 70 so as to have a predetermined space. In addition, the above-described collective wiring 109 is inserted into a space formed between the shaft bracket 110 and the mechanism plate main body, and is guided to the lower component. In addition,
A bearing piece 111 having a bearing hole (not shown) that engages with a shaft pin 62a of the bearing fitting 62 fixed to the game board storage frame 58 is protruded from the upper and lower ends of the shaft fitting 110, and The holding plate 112 is attached in a laminated manner so that the collective wiring 109 housed inside does not jump out.

In the present embodiment, among the members constituting the upper component, an antistatic persistent resin is used as a synthetic resin constituting the ball tank 72 and the ball alignment rail 79. The antistatic and persistent resin includes a polyetheresteramide elastomer (7 to 20% by weight) composed of polyethylene glycol and polyamide (for example, nylon 6, nylon 6,6, etc.), and a styrene-based resin such as ABS resin (93%). To 80% by weight), and is provided as a thermoplastic resin composition having improved antistatic performance, excellent rigidity, molded article surface appearance, and excellent impact strength. is there. And
It is considered that the reason why such a thermoplastic resin composition has antistatic performance for a long period of time is that components that increase the hygroscopicity are collected on the surface of the molded article.

Conventionally, such an antistatic persistent resin has been
It is obvious that the antistatic property is improved as compared with a normal ABS resin or the like used for the ball tank 72 and the ball alignment rail 79, even when compared with a carbon-containing resin used in part. There is an advantage that a ground wire is not required, and the duration of antistatic is greatly extended as compared with a resin in which an antistatic agent is kneaded. In the present embodiment, the ball tank 72 and the ball alignment rail 79 are illustrated as members to which the antistatic persistent resin is applied. However, either one member may be used, or a synthetic resin used for the mechanism plate 70 may be used. All or a part (preferably, a part of the part where the prize ball flows down) may be used.

Next, the configuration of the intermediate component will be described with reference to FIGS. A ball ejection passage 90 is formed on the side of the intermediate component. The ball-dropping passage 90 allows the prize balls drained by the ball-dropping valve 89 to flow down. A passage body 113 is fixed to an upper portion of the intermediate component, and a prize ball payout device 150 is fixed below the passage body 113. Describing in more detail, the passage body 113 is a ball passage 113a, 1 that allows two rows of prize balls to flow down, the flow direction of which is changed left and right by the curve gutter 88.
13b, and a ball detection sensor 114 faces upstream of the ball passages 113a and 113b. The ball detection sensor 114 detects the presence or absence of a prize ball in the ball passages 113a and 113b. When one of the ball detection sensors 114 no longer detects a prize ball, the stepping motor of the prize ball payout device 150 The operation of 163 is stopped to inactivate the award ball payout. The ball detection sensor 114 is connected to the prize ball payout device 150
At the positions where the 27th to 28th prize balls are detected in the ball passages 113a and 113b in the row, they are detachably attached by locking claws 114a. This is to secure one ball lending or prize ball, and to allow one ball to be paid out even if the ball is broken during the ball lending or the prize ball.

Further, a middle portion of the passage body 113 has a front bent portion 115 bent forward, and the ball pressure of the prize ball flowing down at the front bent portion 115 is weakened so that the prize ball payout device 150 is provided. It is designed to supply prize balls. The reason why the bending portion for weakening the ball pressure is bent forward as described above is as follows. That is, the conventional passage body 113 shown in FIG.
In the one having the left and right bent portions 115a bent left and right as described above, the lateral width is increased, so that the lateral width L4 (see FIG. 15) of the intermediate component is inevitably increased. This has a drawback that the width of the U-shaped opening window 71 is small, and it is not possible to cope with the recent backside structure of the game board which is large and complicated. By bending 115 in the front-rear direction, the above-described disadvantage can be solved. Further, as described above, the position of the ball detection sensor 114 can be arranged at a position where one ball can be lent or won for a prize ball, and furthermore, it can be arranged at a position where it is reasonable to rectify the ball. .

On the lower back surface of the passage body 113, a ball stopping device 116 is provided. This boring device 116
As shown in FIG. 8, when the prize ball dispensing device 150 is mounted, the stop lever 127 that engages with the up-and-down elevating rod 125 that rises against the urging force of the spring 126 via the engagement piece 128 is used. The stopper portion 129 swings rearward about the support shaft 131 to move the ball passage 113 of the passage body 113.
The prize ball which retreats from the intrusion hole 130 formed in the a and 113b and flows down the ball passages 113a and 113b is supplied to the prize ball payout device 150.
When the user removes the stop lever 50, the vertical lever 125 is lowered by the urging force of the spring 126, and the stop lever 1 is stopped.
The 27 stopper portions 129 are made to enter the entry holes 130 to automatically close the ball passages 113a and 113b of the passage body 113 so that the prize ball does not flow down.

The passage body 113 configured as described above is
The ball-drop passage 90 and the passage wall 1 protruding from the opposite side.
And a passage body storage section 120 formed one step lower by
The positioning projection 119 extending on both sides of the upper end of the passage body 113 is engaged with the lower end side wall of the curve gutter 88 and is bent forward. Attachment to the mechanism plate main body side by screwing a screw 118 with a mounting piece 117 protruding from the middle left and right front ends of the part 115 corresponding to a mounting boss 122 protruding from the passage body housing part 120 side. Can be. However, even before the screw 118 is screwed, the vertical position of the passage body 113 is set by the engagement piece 121 projecting so as to sandwich the passage body 113 at the vertical position on the passage body housing unit 120 side. By stopping, it can be held in a temporarily fixed state. In the passage body housing section 120, at a position corresponding to the ball detection sensor 114, a sensor contact recessed portion 123 with which the tip of the ball detection sensor 114 contacts is formed, and a corresponding position of the front bent portion 115 is formed. Is formed with a convex portion 124 corresponding to a bent passage.

The prize ball dispensing device 150 attached below the intermediate component is configured to be housed inside a rectangular parallelepiped case 151. Although a specific configuration will be described in detail later, as shown in FIG. 6, the entire case 151 is detachably fastened to a mounting recess 132 formed in the passage body housing 120. . That is, the case 151 is attached to the locking protrusion 133 protruding from an appropriate portion of the periphery of the mounting recess 132.
By engaging the mounting projections 157 projecting from the four front corners of the bracket, positioning and locking of the upper portion are ensured, and in this state, an elastically deformable member formed at the lower center of the mounting recess 132 is formed. By hooking the tongue piece 134 on the front side of the lower end of the case 151, the prize ball dispensing device 150 formed integrally with the case 151 can be easily attached.
The prize ball payout device 150 according to the present embodiment has an internal structure in which the width of the case 151 is reduced, as described later in detail.

The passage body 113 and the prize ball dispensing device 150 are covered with an opening / closing cover 135 which is rotatably supported on one side of the intermediate component. And, the opening and closing cover 135 in the present embodiment is
Some measures have been taken to reduce the width of the intermediate component. That is, the opening / closing cover 135 is formed so as to have a stepped space so that the inside matches the outer shape of the passage body 113 and the prize ball dispensing device 150, and is vertically supported on one side surface outside. Shaft support piece 136 having elongated hole 137
Are integrally formed. Long shaft support hole 1 of shaft support piece 136
37 is formed as a long hole extending in a direction perpendicular to the side surface of the opening / closing cover 135, that is, in the width direction of the opening / closing cover 135. Also, the opening / closing cover 13
In the middle of the other side surface 5, a concave portion 138 is provided in the front-back direction of the side surface.
a is formed, and the engaging portion 13 is formed at the opening end of the concave portion 138a.
8 is formed, and a cutout 135a is formed on a side surface of the opening / closing cover 135 on the pivot side to release contact with the case 151 during rotation.

On the other hand, a pair of bearing pieces 139 project from the cover plate that closes the ball-drop passage 90 at a predetermined interval, and a pair of shaft pins are provided inside the pair of bearing pieces 139 so as to face each other. 140 is protruded. The shaft support hole 137 is engaged with the shaft pin 140 from inside. A locking claw 141 is formed on the passage wall 142 corresponding to the engaging portion 138 so as to protrude therefrom.

The opening / closing operation of the opening / closing cover 135 formed as described above will be described with reference to FIG. 9. Is L3, and the distance from the shaft pin 140 to the open inner surface of the opening / closing cover 135 is L2 (the width of the opening / closing cover 135 from the shaft pin 140). 1
In the present embodiment, where the opening / closing operation of the opening / closing 35 cannot be performed smoothly, the distance from the shaft pin 140 to the open inner surface of the opening / closing cover 135 can be increased from L2 to L1. For example, L2 <L3 Even if L3 <L1
If this is the case, as shown in FIG.
Is closed while maintaining the interval of the maximum radius L1 from the opened state, as shown in FIG.
The turning radius L1 is greater than the distance L3 from the front end corner of the case 151 of the prize ball dispensing device 150 furthest from the distance L3.
, The opening / closing cover 135 can be closed smoothly (however, the side surface of the opening / closing cover 135 on the pivot side comes into contact with the case 151, so that the notch 135
a to escape).

After completely closed, FIG. 9 (C)
, The shaft pin 140 is brought into contact with the left end of the shaft support hole 137 such that the space between the shaft pin 140 and the open inner surface of the opening / closing cover 135 is minimized. As a result, the engaging portion 138 of the opening / closing cover 135 and the locking claw 141 can be completely engaged, and the opening / closing operation of the opening / closing cover 135 having the width L2, which cannot be normally performed, can be performed. Can be.

That is, in this embodiment, the passage 1
13 and the case 151 of the prize ball dispensing apparatus 150 are formed to be narrow and the width L2 of the intermediate component is reduced, even when the opening / closing operation of the opening / closing cover 135 is regulated by the height of the case 151, Since the pivot radius of the opening / closing cover 135 can be increased by the shaft supporting hole 137, the opening / closing operation can be performed smoothly without contacting a part of the case 151.
By moving the opening / closing cover 135 in a direction in which the turning radius becomes shorter, it is possible to match the width of the narrow intermediate component. Further, in the present embodiment, the opening / closing cover 135 is held in a state where it is pivotally supported, and is not a detachable type as in the related art.
Without further loss, and furthermore, since the shaft supporting structure is a method in which the shaft supporting hole 137 of the shaft supporting piece 136 is inserted from the inside into the shaft pin 140 protruding so as to face the bearing piece 139, Since the cover 135 does not move upward or downward, there is an advantage that the cover 135 does not easily fall off.

When the opening / closing cover 135 is not devised, as shown in FIG. 14, the lateral width between the shaft pin 140 and the passage wall 142 (the lateral width of the intermediate component) is the bent angle and the passage body 113. Even if the prize ball dispensing device 150 is formed to be thin, the case 151 of the prize ball dispensing device 150 and the shaft pin 14
It cannot be shorter than the distance L3 to 0. However, in the case shown in FIG. 14, since the passage body 113 and the prize ball payout device 150 are formed thin, the width of the intermediate component provided with the conventional passage body 113 and the prize ball payout device 150 shown in FIG. It can be formed smaller than the dimension L4. This is because the left and right bent portions 115 of the conventional passage body 113
This is because the width dimension of “a” is longer than the distance L3 between the case 151 of the winning ball payout device 150 and the shaft pin 140.

Next, the structure of the winning ball payout device 150 covered by the above-mentioned opening / closing cover 135 will be described with reference to FIGS. The prize ball payout device 150
As described above, the case 151 is formed collectively in the rectangular parallelepiped case 151. This case 151 is completed by being divided into right and left parts and assembling them. In each case 151a, 151b, a ball passage 153 communicating with the two rows of ball passages 113a, 113b of the passage body 113 in front of the case 151 (because the internal structure of each case 151a, 151b is almost symmetrical. (The symbols a and b are omitted.)
Is bent in the shape of a “<”, and the ball passage 153 is formed.
The award balls entered from the ball inlet 152 at the upper end of the ball passage 153 are separated one by one by a sprocket 175 provided in the middle of the ball passage 153, and are discharged from the outlet 154 at the lower end of the ball passage 153.

And is rotatably supported via the. More specifically, the sprockets 175 are provided at a plurality of (three) protruding portions 178 protruding from both ends of the columnar member while maintaining an interval for receiving a prize ball, and provided at the base of each protruding portion 178. A concave portion 177 for receiving and guiding a prize ball between the projecting portions 178; a gear 176 projecting along the outer periphery of the columnar member; and a plurality of gears projecting along one outer periphery of the gear 176. (Six) detection protruding pieces 179 are integrally formed of synthetic resin, and a center hole 180 formed in the center of the cylindrical member is inserted into one of the case 1.
It is rotatably supported by being inserted into a rotating shaft 190 that is inserted and supported slightly below and substantially forward of the center of 05a. Note that the other end of the rotating shaft 190 is supported by a support hole 192 formed in the case 151b when the other case 151b is assembled.

The sprocket 175 rotatably supported as described above is driven to rotate by the stepping motor 163 housed and supported in the motor housing space 160 formed behind the ball passage 153. That is, the stepping motor 163 is fixed to a motor fixing plate 162 provided so as to close the front surface of the one case 151a, and the gear 165 is fixed by projecting the output shaft 164 forward of the motor fixing plate 162. The gear 165 is a gear 1

A board 166 (printed wiring board) on which the stepping motor 68 is mounted is provided.
The copper wire extending from 63 is connected only in a soldered state, and the motor fixing plate 162 is only in a state where its center portion is in contact. Connector 16
7 is a wiring from outside (a winning ball payout control board 25 described later).
7 are connected, and the conductive line 168 is connected.
Connects the substrate 166 to the sensor substrate 169 on which the ball passing sensor 171 and the photo sensor 172 are provided. The sensor substrate 169 is fixed by inserting a support hole 170 formed in the substrate 169 into a substrate locking pin 196 of a partition member 193 described later.

The stepping motor 175 constructed as described above is fixed to the case 151a by:
The board 166 is engaged with engagement grooves 181 formed on the upper left and right sides of the motor housing space 160. In this state, the through holes 173, 174 (173 are formed in the motor fixing plate 162

Is firmly fixed in the case 151. In addition, the one case 151a and the other case 151b are screwed together with the fastening hole 182 and the screw hole 185, as well as the fastening hole 188 and the screw hole 1 which are located diagonally to the above.
This is also performed by screwing a set screw 208 to the screw 89. That is, the prize ball payout device 150 in the present embodiment.
The final assembling is such that it can be assembled with only two setscrews 208.

A circular heat radiation hole 161 is formed on one side of the case 151a facing the rear surface of the stepping motor 163. Is formed with a connection opening 159 for connection to the semiconductor device.

In the state where the motor fixing plate 162 and the substrate 166 are fixed as described above, the gear 165 fixed to the output shaft 164 of the stepping motor 163
(Hereinafter, referred to as a small-diameter gear) and a gear 176 of the sprocket 175 (hereinafter, referred to as a large-diameter gear) are engaged (the gear ratio is 1: 2). Also, sprocket 175
As shown in FIG. 12, the projection 17
8 and the recess 177 penetrate into the ball passage 153. The ball 153 rotates at a bent portion of the ball passage 153 and accommodates the prize ball received between the protruding portions 178, and releases the ball at an obliquely lower point to discharge the ball. An award ball is paid out from the exit 154. The large-diameter gear 17 of the sprocket 175
The protrusion 178 and the recess 177 formed on the left and right of
They are formed alternately with each other. For this reason, the prize ball paid out from one ball passage 153 and the other ball passage 153
The prize balls paid out from are not paid out at the same time, but are paid out alternately. Also, the protrusion 1
The prize ball received between 78 is not only received by the concave portion 177, but also protrudes from the inner wall of each case 151a, 151b, and is inserted into the arc-shaped guiding piece 156 between the rotating shaft 190 and the protruding portion 178. , And comes into contact with the ball contact piece 202 of the ball passage detection member 200 that is swingably provided facing the lever side opening 155 formed at a position facing the guide piece 156. I have.

The structure for mounting the above-mentioned ball passage detecting member 200 will be described. As shown in FIG.
A partition member 193 having a side surface inverted L-shape constituting the inner side wall of the ball passage 153 formed on the side is disposed. As shown in FIG.
a, 151b are positioned and fixed by being sandwiched by sandwiching notches 158 formed on the rear side surface of the case 151a, and as shown in FIG. It is arranged to fit neatly. The partition member 193 has a guiding piece 1 for guiding the prize ball entering the ball entrance 152 of the other case 151b into the ball passage 153 in the upper rear portion thereof smoothly.
95 is projected, a board locking pin 196 is projected forward of one side of the side face, and a locking pin 197 is projected behind the board locking pin 196.
A through hole 198 is formed between the locking pin 96 and the locking pin 197.

The support hole 170 of the sensor board 169 is inserted into the board locking pin 196 to support the sensor board 169. The through hole 198 is inserted and supported by one of the cases 151a. Oscillating shaft 19
The ball passage detecting member 200 which is pivotally supported at 9 through a washer 206 so as to freely swing therethrough penetrates. In addition,
The other end of the swing shaft 199 is supported by a support hole 207 formed in the other case 151b.

As shown in FIG. 10, the ball passage detecting member 200 supported by the swinging shaft 199 has the swinging shaft 199 swingably supported by shaft holes 201 formed at the rear portions of both ends thereof. And ball contact pieces 202 are attached to both ends thereof in a downward direction.
, And a detection piece 203 is protruded substantially in the center toward the front. The other end of a spring 205, one end of which is locked to the locking pin 197, is locked to a locking piece 204 cut out above the detection piece 203.

Thus, the ball contact piece 202 is attached to each ball passage 1
Spring 2 so as to face 53 lever opening 155
05 when there is a prize ball moved by the sprocket 175.
The ball passing detection member 200 is swung against the urging force of No. 5, and whether or not the detecting piece 203 has entered the ball passing sensor 171 by the swinging operation and the payout operation of the prize ball is surely performed. It can be detected. The sensor for detecting the number of paid-out prize balls is a photo sensor 172, and the photo sensor 172 is a large-diameter gear 1
The detection operation is performed when the detection protruding piece 179 protrudingly formed on the rear surface of 76 crosses.

As described above, the prize ball payout device 15 according to the present embodiment.
Although the configuration of No. 0 has been described in detail, the prize ball payout device 150 according to the present embodiment includes a ball passage 153 in a case 151 in which a ball passage 153 in which a prize ball flows down in a line is formed.
And a stepping motor 163 for driving the sprocket 175 for receiving and paying out the prize balls one by one.
Since the rotation shaft 190 of the sprocket 175 and the output shaft 164 of the stepping motor 163 are arranged in parallel, and the rotation shaft 190 of the sprocket 175 and the output shaft 164 of the stepping motor 163 are connected by gears 176 and 165, FIG. As shown, the ball passage 153, the sprocket 175, and the stepping motor 163 are
0, the width dimension W is shorter than the depth dimension D, and the width dimension W is significantly larger than that of the conventional case where the sprocket is directly fixed to the output shaft of the stepping motor. Since the size can be reduced, the width of the intermediate component of the mechanism plate 70 in which the prize ball payout device 150 is provided can be reduced, and conversely, the inner width of the U-shaped opening window 71 of the mechanism plate 70 can be increased. In addition, it is possible to easily cope with a game board having a back surface structure which is becoming more complicated and larger in recent years, thereby increasing the degree of freedom in designing the arrangement of the game devices of the game board.

As shown in FIG. 12, the relationship between the number of teeth of the gear 176 formed on the outer periphery of the sprocket 175 and the number of teeth of the gear 165 fixed to the output shaft 164 of the stepping motor 163 causes Since the number of teeth is larger than the number of teeth of the small-diameter gear 165, the disadvantage of the small-sized stepping motor 163 that the vibration generated due to the roughness of the number of steps becomes large is different from that of the small-diameter gear 165. Since it can be weakened by the gear ratio with the large-diameter gear 176, a smooth prize ball payout operation is performed over a long period of time, and the load on the stepping motor 163 from the prize ball can be reduced.
Durability can be improved.

As shown in FIG. 11, a gear 176 formed on the outer periphery of the sprocket 175
3, and the side surface of the gear 176 is also used as an inner side wall of one ball passage 153 (a ball passage formed on the case 151b side), so that the other ball is used. The same member as the partition member 193 used as the inner side wall of the passage 153 (the ball passage formed on the case 151a side) is used for the one ball passage 153 (the case 151a).
Since there is no need to provide the same in the ball passage 153 (the ball passage formed in the case 151b), the same structure as the partition member 193 is provided in the ball passage 153 (the ball passage formed in the case 151b). Compared to the case, the prize ball payout device 15
The width W of 0 can be formed small.

Further, as shown in FIG.
Is provided with a ball passage detection member 200 that is swung by the prize ball during the rotational movement of the prize ball received by the sprocket 175, and a ball passage sensor 171 that detects the swinging operation of the ball passage detection member 200. Since it is provided, it is possible to know very accurately whether or not the payout operation of the ball has been performed. As in the conventional embodiment, such as a form in which the end of dispensing is indirectly detected by a projection formed on a sprocket, it is more accurate than one that controls whether or not a ball has been dispensed based on a prediction. It is clear that the ball passing sensor 171 other than the prize ball is different from the type in which the passing of the prize ball is detected by a sensor of the light emitting / receiving system (there may be a reaction with dust other than the ball). The accuracy has been greatly improved because of the inability to operate.

Further, the prize ball payout device 15 according to the present embodiment.
0 is a sprocket 175, a stepping motor 16
3, substrate 166, motor fixing plate 162, partition member 19
3. The parts such as the ball passage detection member 200 and the
1a and 151b are arranged so as to be engaged with a predetermined position with respect to one of the cases 151a. Therefore, the other case 151b is applied in a state where the components are assembled in one of the cases 151a in advance, and thereafter, Assembling can be performed by a simple operation of merely screwing the set screw 208 into the two screw holes 185 and 189 located on the diagonal lines.

The description of the intermediate components of the mechanism plate 70 has been completed above. Next, the lower components of the mechanism plate 70 will be described with reference to FIGS. 2, 16 to 18. As shown in FIG. 2, a winning ball payout passage 220 is formed on the rear side of the lower component portion at one upper portion thereof.
The upper plate communication port 221 is formed at the lower end of the upper plate. The upper plate communication port 221 guides a prize ball to the upper plate 12 provided on the front face of the ball game machine 1. A communication passage 222 is connected to one side of the upper plate communication port 221.
The surplus ball passage 223 is connected to the end of the second. When a large number of prize balls based on the winning are paid out and the upper plate 12 is filled with the prize balls, and finally reaches the upper plate communication port 221 and the prize balls are further paid out, the prize balls are connected to the communication path. 2
It is led to the surplus ball passage 223 via the connection pipe 22 and then discharged to the lower plate 21 via the connection gutter (not shown). When the prize ball is further paid out, the lower plate 21 is also full, but as shown in FIG. 18, when the lower plate 21 reaches the full tank detection plate 224 provided on one side wall of the surplus ball passage 223. , The full tank detection plate 224 is pressed by the prize ball and swings outward around the support shaft at the upper end,
As a result, the full tank switch 225 is turned on, and the driving of the stepping motor 163 of the prize ball dispensing device 150 is stopped to inactivate the prize ball dispensing operation. Is also stopped.
