DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<< Form 1 >>
FIG. 1 shows a rear view and a side view of a pachinko machine 1 as an example of a gaming machine. A mechanism ball 3 provided at the rear of a front gaming board 2 has a gaming ball tank 4 from above. A game ball payout device 5, a control device 6, a winning ball detection device 7, a game ball launching device 8, and the like are installed, and the control device 6 is positioned substantially directly below the game ball tank 4. A machine frame 9 is provided around the mechanism plate 3.
As shown in FIG. 2, the game ball tank 4 has a dish shape in which the bottom surface is inclined and the upper side is opened, and the game ball stored therein is connected to the game ball via a guide rod 4 a connected to the bottom surface. The game ball payout device 5 is supplied to the payout device 5. The game ball payout device 5 is provided in the control device 6, and includes a board 11 that controls the game contents starting with the operation control of an electric game member (not shown) installed on the game board 2. In accordance with the instructions, a predetermined number of game balls supplied from the game ball tank 4 are paid out to the tray 10 on the front surface of the pachinko machine 1. Further, the control device 6 has a base 12 to which the substrate 11 is screwed and a box-shaped cover 13 to be screwed to the base 12 so as to cover the substrate 11 leaving the upper side where the connection terminals and the like are provided. The mechanism plate 3 is installed with screws through mounting brackets 21 and 21 fixed to the base 12.
1 and 2, the first inclined surface 14 that decreases from the left end of FIGS. 1 and 2 toward the right and the second inclined surface 15 that decreases from the right end to the left as the start end. Then, the end points of both inclined surfaces 14 and 15 are joined together, and a guide path 17 is formed which includes a falling surface 16 that becomes lower from the substrate 11 side starting from the substrate 11 side. Further, as shown in the cross-sectional explanatory view A and the second inclined surface 15 of the cover 13 shown beside the side view in FIG. 1, a terminal connected to the dropping surface 16 is provided around the first inclined surface 14 and the second inclined surface 15. Except for the above, guide walls 18 and 18 are erected. The falling surface 16 is set so as not to be positioned directly above other components such as the game ball launching device 8 below the control device 6 in the vertical direction.
[0007]
Therefore, in the pachinko machine 1 configured as described above, when the game ball 19 accidentally spilled from the game ball tank 4 falls on the cover 13, the first inclined surface 14 or the second Guided by the two inclined surfaces 15 to the dropping surface 16 and further guided to the end by the dropping surface 16, the game balls 19 always fall from the end of the dropping surface 16 as indicated by the arrows in order. At this time, the guide walls 18, 18 provided around the first and second inclined surfaces 14, 15 are prevented from dropping from other than the dropping surface 16, and at the same time, by the guide walls 18 positioned on the substrate 11 side, It is possible to prevent the game ball 19 moving along the guide path 17 from coming into contact with the substrate 11. And since the machine frame 9 without an electric member is only arranged below the fall surface 16, even if the game ball 19 falls here, there is a risk of causing problems such as short circuit or damage. There is no.
As described above, according to the above embodiment, the game ball 19 dropped on the cover 13 by the guide path 17 is guided to a predetermined position (end of the fall surface 16) regardless of the place of the fall, and the machine frame is not affected by the fall. 9 can be dropped. Therefore, it is possible to prevent the game ball 19 from being stored on the control device 6 and to eliminate the possibility of short-circuiting the circuit due to contact with the substrate 11, and the game ball 19 dropped from the control device 6 has a lower component. It is also possible to reliably prevent the possibility of short circuiting and damage. In addition, the guide wall 18 provides both effects of reliably guiding the game ball 19 and preventing contact with the substrate 11 during guidance.
[0008]
<< Form 2 >>
On the other hand, the guiding path can be realized by other structures. FIGS. 3 and 4 show the modified example, and the same reference numerals as those of the first embodiment indicate the same members, and thus the description thereof is omitted.
Here, the guide path 17a is a continuous inclined surface 20 starting from the left end and descending as the entire surface of the cover 13 goes to the right end, and the guide wall 18 is around the continuous inclined surface 20 except for the end of the right end. It is erected. Therefore, the game balls 19 that have fallen on the cover 13 are guided to the end by the continuous inclined surface 20 at any location as indicated by the arrows, and fall on the machine frame 9 from the end.
Therefore, also in this form 2, the game ball 19 dropped on the cover 13 by the continuous inclined surface 20 is not stored on the control device 6 but guided and dropped to a place unaffected by the fall of the game ball 19. As a result, it is possible not only to prevent the game ball 19 on the control device 6 from being short-circuited but also to suitably prevent the game ball 19 dropped below the control device 6 from being short-circuited or damaged in other components. Further, both effects of reliably guiding the game ball 19 by the guide wall 18 and preventing contact with the substrate 11 during guidance can be maintained. In particular, in this embodiment, it is only necessary to form a simple continuous inclined surface 20, so that the structure is simpler and less expensive than Embodiment 1.
[0009]
Note that the predetermined position for guiding the game ball by the guide path is not limited to the positions of the first and second embodiments, but depends on the lower constituent part of the control device 6, so that it can be changed as appropriate according to the position of the lower constituent part. It ’s fine. Also, the specific shape of the guide path can be formed by an inclined flat surface, a concave groove that can be guided to a predetermined position, or an inclined curved surface, and the guide wall is not continuous as in the above embodiment. If it is possible to prevent the game ball from detaching from the guide path, it can be provided in an intermittent manner. Further, if the game ball can be reliably guided only by the shape of the guide path, the guide wall may be omitted.
In addition, a means for collecting a game ball by providing a tray of a dropped game ball or the like below the control device may be employed.
[0010]
【The invention's effect】
According to the first aspect of the present invention, the game ball dropped on the cover by the guide path composed of the first and second inclined surfaces and the falling surface is not affected by the falling regardless of the dropping location. It can be guided to the falling surface corresponding to and dropped from there. Therefore, it is possible to prevent the game balls from accumulating on the control device, to eliminate the possibility of short-circuiting the circuit due to contact with the substrate, and for the game balls dropped from the control device to contact other components to cause a short circuit. It is possible to reliably prevent the possibility of damage.
According to the second aspect of the invention, in addition to the effect of the first aspect , the guide wall enables both the reliable guidance of the game ball to the falling surface and the prevention of contact with the substrate during guidance. .
