In addition, a support piece portion (not shown) in which a screw hole is formed in alignment with the mounting hole 138 of the detection switch 130, a cover support pin 116a that protrudes forward from the base portion 116, and the like are formed.
[0045]
The stopper surface 111 and the engaged surface 112 are stipulated in position dimensions so as to be able to engage with the engaging rib 35b and the engaging wall surface 35c in the assembly mounting portion 35, respectively, and the switch base 110 (detection assembly 100A). Is attached to the assembly mounting portion 35, the side end surface of the stopper surface 111 (the left end surface in the mounting posture) is engaged with the engaging rib 35b, and the engaged surface 112 is engaged with the engaging surface 35c. The switch base 110 is configured to be sandwiched between the engagement rib 35b and the engagement wall surface 35c.
[0046]
The lever member 120 penetrates in the front-rear direction and has a bearing hole 124 that can be fitted to the support shaft 114 of the switch base 110, and a ball formed flat on the upper surface side of the lever member 120 according to the inclination of the right bottom surface 411a of the tank member. The detecting switch 130 is formed by projecting downward on the receiving surface 125, a regulating projection 121 that is projected downward on the swinging end side of the lower surface of the lever member and can come into contact with the stopper surface 111, and is projected downward on substantially the middle position of the lower surface of the lever member. The detection projection 122 and the like engaged with the lever 132 are formed by the same molding means as the tank member 41 and the switch base 110.
[0047]
The detection switch 130 is a so-called micro limit switch. A detection lever 132 is swingably attached to the main body 131 and is always urged and supported upward by a spring disposed inside the switch main body. Yes. Mounting holes 137 and 138 for mounting the switch are formed in the main body 131 so as to penetrate the main body. In addition, a signal line for inputting / outputting a contact signal of the detection switch is connected to the main body 131 by a connector. The signal line is supported on the upper surface of the support bar 38 and traverses on the bar and is similar to the ground wire 46. To the terminal board 96.
[0048]
A switch cover 140 for fixing the detection switch 130 is attached to the front side (game board side) of the detection switch 130. The switch cover 140 is opposed to the base portion 116 and similarly has an L-shaped rib 146 and a cover body 141 that covers the side surface of the detection switch main body, and projects forward from the cover body 141. A holding piece 142 whose end is bent downward is formed, and a knob 143 formed so as to connect the cover surface and the upper side of the holding piece.
[0049]
The cover body 141 is formed with a cover support pin 146a that protrudes forward from the base portion 116, a support hole 146a that can be engaged and disengaged, and a fixed hole 148 that is formed in alignment with the mounting hole 138 of the detection switch. Yes. The switch cover 140 is molded by the same molding means using the same resin material as the switch base 110, the lever member 120, and the like.
[0050]
These constituent members 110, 120, 130, and 140 are assembled to form the detection assembly 100A.
[0051]
The lever member 120 is attached by fitting the bearing hole 124 to the support shaft 114, pivoting the lever member 120 to the support shaft 114, and screwing a seat screw 154 or the like from the tip of the support shaft 114. The member 120 is pivotably connected to the switch mounting portion 113. When the lever member 120 is attached, when the lever member 120 is about to tilt downward beyond a predetermined swing angle, the regulation protrusion 121 abuts against the stopper surface 111 to regulate the tilt, and the detection switch 130 is excessively moved. It functions so that a pressing load does not act.
[0052]
On the other hand, the detection switch 130 is attached by first fitting and connecting the mounting hole 137 of the detection switch 130 to the pin on the distal end side of the support pin 117. By this fitting connection, the vertical and horizontal positions of the detection switch 130 are positioned. Next, the knob 143 is pinched to fit the switch cover support hole 146 a into the cover support pin 116 a, and the switch cover 140 is attached so that the cover body 141 covers the front of the detection switch 130. Then, a fixing screw 158 is inserted from the front side of the cover body 141 through the fixing hole 148 and the detection switch mounting hole 138, and screwed into the screw hole of the support piece. Thus, the detection switch 130 is fixed and attached to the switch base 110 so as to be sandwiched between the seating surface of the support pin 117 and the front end surface of the support piece portion and the cover body 141 of the switch cover 140.
[0053]
The pin diameter of the support pin 117 is made slightly smaller than the hole diameter of the mounting hole 137, and an engagement pin having substantially the same diameter as the mounting hole 137 is formed on the switch holding surface side of the switch cover 140 so as to project. The engagement pin and the mounting hole 137 of the detection switch 130 may be fitted and connected first. That is, first, the mounting hole 137 of the detection switch 130 is fitted and connected to the engagement pin of the switch cover 140 (press-fit connection) to hold the detection switch 130 on the switch cover 140, and then the knob 143 is pinched to detect the detection switch. 130 and the switch cover 140 may be integrally attached to the switch base 110. According to such a configuration, after the assembly of the pachinko machine is completed and installed in the game facility, for example, when performing maintenance replacement of the detection switch 130, the position is relatively deep on the front side of the base frame body. It is possible to easily attach / detach the detection switch 130 to / from the switch mounting portion 115 (see the two-dot chain line in FIG. 11).
[0054]
In these configurations, since the detection switch 130 is screwed via the switch cover 140, the tightening force from the seating surface of the fixing screw 158 is distributed by the switch cover 140, and an unreasonable tightening force acts on the switch body 131. Without the risk of damaging the detection switch 130. In this configuration, the detection switch 130 is positioned using the support pin 117 provided on the detection switch mounting portion or the support pin provided on the switch cover, and is fixed together with the switch cover 140 using the fixing screw 158. The detection switch 130 can be positioned and attached at an accurate position by a simple operation of screwing only one screw.
[0055]
In this way, when the lever member 120 and the detection switch 130 are attached to the switch base 110, the detection assembly 100A is configured in which the lever member 120 and the detection switch 130 are held in alignment with each other in the arrangement relationship. The In the detection assembly 100A, the detection protrusion 122 of the lever member and the detection lever 132 of the detection switch 130 are vertically engaged with each other in a normal arrangement posture, and the lever member 120 is always upward due to the spring force built in the detection switch 130. Is held at the swing angle position urged by.
[0056]
As shown in FIG. 8, the detection assembly 100 </ b> A is attached to the assembly attachment portion 35 from the back side of the base frame body 30. The operator grasps the detection assembly 100A, inserts the lower end portion of the switch mounting portion 115 into the detection opening 35a, and makes the engaged surface 112 contact the engaging wall surface 35c to guide it to the engaging wall surface 35c. Then, the detection assembly 100A is moved downward.
[0057]
Then, the lower surface of the stopper surface 111 is moved downward until it contacts the upper surface around the detection opening 35a, the side end surface of the stopper surface 111 and the side end surface of the engagement rib 35b are engaged, and the switch base 110 is engaged with the engagement rib. It is held between 35b and the engaging wall surface 35c. At this time, the left and right lower end portions of the switch mounting portion 115 are sandwiched and held by the engagement protrusions 35d and 35d formed on the support bar portion 38 corresponding to the lower back portion of the detection opening 35a. As a result, the detection assembly 100A is attached to the assembly attachment portion 35, and the ball receiving surface 125 of the detection lever is held in an upward attachment posture.
[0058]
When the detection assembly 100A is attached, a cable holding space for passing a cable such as the ground wire 46 is formed between the lower surface of the switch cover 140 and the upper surface of the support frame portion 38 of the base frame body. A holding piece 142 is positioned in front of the holding space to hold the cable in the holding space. Thereby, the cables passing through the upper surface of the support bar 38 are effectively prevented from falling off.
[0059]
Next, the tank member 41 is attached to the tank member attachment portion 33 above the base frame body. The tank member 41 is attached in such a manner that the right and left receiving attachment portions 414 and 414 of the tank member are engaged with the dowels 33b and 33b on the base frame side in a state where the ground metal fitting 45 is temporarily fixed to the tank member 41. This is done by screwing from the side of the parts 414, 414. The ground metal fitting 45 is moved to the ground metal fitting attaching portion 36 along with the attachment of the tank member 41, screwed together with the round crimp terminal of the ground wire 46 into the screw hole 36n, mechanically fixed and electrically connected. Earth ground potential.
[0060]

FIG.
[0061]
For this reason, when a large number of game balls are stored in the storage space 410 of the tank member and the game ball is also positioned above the ball receiving surface 125, the lever member 120 receives the pressing force (mass) from the game ball and moves downward. In general, the detection lever 132 of the detection switch is swung downward to hold the switch contact in a closed state (or an open state in the case of reverse logic).
[0062]
On the other hand, when the number of game balls stored in the storage space 410 of the tank member decreases due to the payout operation of the prize ball device 53 and the like, and there is no game ball on the upper part of the ball receiving surface 125 (ball-out state), the lever member 120 Therefore, the lever member 120 is tilted upward by the biasing force of the spring built in the detection switch 130, and generally the switch contact of the detection switch 130 is opened. It is held in a state (closed state in the case of inverse logic).
[0063]
These detection signals from the detection switch 130 are transmitted to the game ball supply device on the game facility side via the terminal board 96, and the game ball supply device receives the storage space 410 based on the detection signal from the detection switch 130. When the game balls stored in the tank are out of ball (when they are reduced below a predetermined amount), a predetermined number of game balls are supplied to the tank member 41.
[0064]
Next, with reference to FIG. 12 to FIG. 15, the winning ball cut detection device 200 of the second embodiment will be described.

On the other hand, when the number of game balls stored in the storage space 410 of the tank member decreases due to the payout operation of the prize ball device 53 and the like, and there is no game ball on the upper part of the ball receiving surface 125 (ball-out state), the lever member 120 Therefore, the lever member 120 is tilted upward by the biasing force of the spring built in the detection switch 130, and generally the switch contact of the detection switch 130 is opened. It is held in a state (closed state in the case of inverse logic).
[0079]
These detection signals from the detection switch 130 are transmitted to the game ball supply device on the game facility side via the terminal board 96, and the game ball supply device receives the storage space 410 based on the detection signal from the detection switch 130. When the game balls stored in the tank are out of ball (when they are reduced below a predetermined amount), a predetermined number of game balls are supplied to the tank member 41.
[0080]
In the above-described embodiments, the engagement protrusions 35d and 35d have exemplified the form in which the left and right end faces of the switch mounting portions 115 and 215 are sandwiched, but these engagement protrusions are on the front side of the switch mounting portions 115 and 215. The switch mounting portion may be sandwiched in the front-rear direction between the engagement protrusion and the passage wall surface 34. Further, in the example, the case where the detection opening 35a is opened only on the upper surface is illustrated. However, for example, in the winning ball cut detection device 200 of the second embodiment, the detection opening is formed on the back side (the passage wall surface 34) of the base frame 30. Side) may be provided. According to such a configuration, the tank member 41 can be attached to and detached from the base frame body 30 in a horizontal manner, and it is possible to easily attach the prize ball break detection device and the grounding metal fitting.
