  The front wall surface (wall surface) 42 of the ball tank 18 has an opening that communicates the housing space 34 and the outside at a position corresponding to the second opening 28 b of the case member 28 disposed in the tank 18. The portion 42a is opened, and the mounting base member 32 holding the detection switch 30 through the opening 42a is configured to be inserted into and removed from the accommodating space 34. Further, as shown in FIG. 3, a locked portion 42b is formed on the front wall 42 in the vicinity of the opening 42a, and a lock described later provided on the mounting base member 32 is formed on the locked portion 42b. The stop portion 60a is locked so as to be detachable.

  As shown in FIGS. 4 and 5, each of the ball sensing operation members 26 is supported by the support shaft 36 in a vertical and vertical orientation, and has a boss portion 26a formed with a support hole through which the support shaft 36 passes. An operation portion 26b that extends leftward from the boss portion 26a and is positioned in the accommodation space portion 34, and a ball receiving portion that extends downward from the boss portion 26a and receives the pressure of the storage ball (game ball) 16 26c is integrally formed, and the operation portion 26b is configured to press an actuator lever 30b (described later) of the detection switch 30. The boss portion 26a is integrally formed with a latching portion 26d extending leftward, and is attached between the latching portion 26d and a latching claw 53a formed on the bottom wall 53 of the case member 28. A coil spring 54 as a biasing member is elastically applied, and the latching claw 53a and the latching portion 26d are always biased by the coil spring 54 so as to attract each other. Thereby, the lower end of the ball receiving portion 26c extending downward from the boss portion 26a in a substantially right-angle relationship with the operation portion 26b and the operation portion 26b extending to the left side from the boss portion 26a is The ball sensing operation member 26 is biased to the first position (the state shown in FIG. 4) where the game ball is displaced upstream in the flow direction.

  The bottom wall 53 of the case member 28 is formed with a rising portion 56 that rises at a position close to the first opening 28a, and at the upper end of the rising portion 56 on the left side (one end side of the ball tank 18). A guide portion 56a extending in parallel with the bottom wall 53 is formed along the insertion / removal direction of the attachment base member 32, and the guide portion 56a is attached to the accommodation space portion 34. It functions to guide the base member 32 when inserting and removing 32. The bottom wall 53 and the guide portion 56a position the mounting base member 32, that is, the detection switch 30, in the vertical direction. Further, a positioning piece 53b for restricting rearward movement of the attachment base member 32 (movement toward the mechanism set panel C) is projected on the bottom wall 53 of the case member 28, and the attachment base member 32 is provided on the positioning piece 53b. The attachment base member 32 is configured to be positioned at a fixed position with respect to the accommodation space portion 34 by contacting the rear end (front end in the insertion direction).

  As shown schematically in FIG. 8, the detection switch 30 for detecting the presence or absence of a storage ball (game ball) 16 in the ball tank 18 has an actuator lever 30b as a detection unit and a contact 30c on a main body 30a. A micro (limit) switch of the type is used, and the contact 30c together with the actuator lever 30b is moved in and out with an elastic biasing force by the direct pressing operation by the operation portions 26b and 26b on the ball sensing operation member 26, and is turned on / off. It is set to be. That is, as shown in FIGS. 5 and 7, the detection switch 30 opens the contact point 30c before the operation of the actuator lever 30b by the operation portion 26b of the ball sensing operation member 26 (with the ball), and the current is turned off. As shown in FIG. 6, in a state where the operation portion 26 b of one sphere sensing operation member 26 is operating the actuator lever 30 b (no sphere state), the contact 30 c is closed and the current is turned on, and no sphere signal is output. Called. And this detection switch 30 is electrically connected to the control apparatus (not shown) provided in the pachinko machine P via the wiring which is not shown in figure. When the no-ball signal is input from the detection switch 30, the control device operates a notification means such as a lamp or an alarm provided on the front side of the pachinko machine P, and sends a ball to the player or pachinko hall clerk. It is configured to notify that an absence state has occurred.

  As shown in FIG. 8, the mounting base member 32 on which the detection switch 30 is detachably mounted includes an inverted L-shaped main body 58 having a side plate 58b erected on one side edge of the bottom plate 58a, and a side plate 58b. It is basically composed of an elastically deformable operation knob 60 formed on the front end edge and extending forward by a predetermined length. The side plate 58b is provided with two holding pins 62 and 62 as a holding portion extending above the bottom plate 58a. The holding pins are inserted into the through holes 30d and 30d formed in the main body 30a of the detection switch 30. By inserting 62, 62, the detection switch 30 is engaged and held on the mounting base member 32 with the actuator lever 30b facing upward (see FIG. 3). The mounting base member 32 to which the detection switch 30 is engaged and held is configured to be detachable from the housing space 34 from the outside through an opening 42a formed in the ball tank 18. As shown in FIG. 7, the actuator lever 30b of the detection switch 30 is positioned so as to face below the operation portions 26b, 26b of the both ball sensing operation members 26, 26 in the state of being accommodated and set in the accommodation space 34. The A locking portion 60a that is removably locked to a locked portion 42b formed on the ball tank 18 is provided on the outer side of the operation knob 60 (on the side away from the bottom plate 58a). When the base member 32 abuts on the positioning piece 53b and is restricted from moving, the locking portion 60a is locked to the locked portion 42b, whereby the accommodation space portion 34 of the mounting base member 32 is retained. It is configured to prevent falling off.

(Effects of Example)
Next, the operation of the detection switch mounting structure in the gaming machine according to the embodiment configured as described above will be described. The case member 28 in a state in which the ball sensing operation members 26 and 26 are pivotally supported on the support shaft 36 and the coil springs 54 are respectively hung between the respective latching portions 26d and the latching claws 53a. From above. At this time, the front and rear projecting pieces 50 and 50 of the case member 28 are fitted into corresponding grooves formed on the front and rear inner sides of the ball tank 18, and the front and rear and the left and right thereof are the left wall surface 24 of the ball tank 18, and the regulation projection. The position of the case member 28 is regulated by abutting against the portion 40 and the front and rear wall surfaces 42, 44, and the case member 28 is suitably positioned with no rattling against the ball tank 18. Further, the engagement protrusion 52a formed on the operation piece 52 of the case member 28 is engaged with the engaged recess 51 of the ball tank 18, so that the case member 28 is reliably prevented from falling off the ball tank 18. Is done. In this state, the ball receiving portion 26c of one of the ball sensing operation members 26 faces one of the ball passages in the rectifying rod 20, and the ball receiving portion 26c of the other ball sensing operation member 26 faces the other ball passage. It becomes.

  Next, the mounting base member 32 in which the detection switch 30 is engaged and held via the holding pins 62 and 62 is inserted into the ball tank 18 through the opening 42 a with the operation knob 60. . The mounting base member 32 is accommodated in the accommodating space 34 while its upper and lower ends are guided by the bottom wall 53 and the guide portion 56a of the case member 28, and the rear end of the base member 32 is the positioning piece 53b. Insertion (movement) is restricted by contact with the locking portion 60, and the locking portion 60 a of the operation knob 60 is locked to the locked portion 42 b of the ball tank 18, so that it is set in the receiving space portion 34. . At this time, as shown in FIG. 6, the actuator lever 30b of the detection switch 30 is disposed below the operation portions 26b, 26b of the both-sphere sensing operation members 26, 26 disposed in the housing space 34 and disposed in the case member 28. Is positioned and can be turned on / off by the operation portions 26b and 26b. Note that the wiring connected to the front end (the end facing the opening 42a) of the detection switch 30 is led out from the opening 42a to be electrically connected to the control device.

  In the pachinko machine P in which the detection switch 30 is disposed in the ball tank 18 as described above, before the game ball 16 is supplied from a ball replenishment facility (not shown), that is, the storage ball (game ball) 16 in the ball tank 18. In a state where no ball is present, the ball receiving portion 26c does not receive the pressure of the storage ball (game ball) 16, and therefore both the ball sensing operation members 26, 26 are in the first position under the biasing force of the corresponding coil spring 54. Thus, the operation portion 26b is displaced toward the detection switch 30 and is in an operation state with respect to the actuator lever 30b, which is set as “no ball (on) condition” (see FIG. 4). Accordingly, when the no-ball signal from the detection switch 30 is input to the control device and the notification means is activated, the pachinko hall clerk can recognize that the ball tank 18 is currently in the no-ball state. it can.

  The game ball 16 supplied from the ball supply facility into the ball tank 18 moves to the ball outlet 18 a side while rolling on the bottom surface, flows into both ball passages of the rectifier rod 20, and from the lower end of the delivery passage 22. Stored sequentially. Then, the game balls 16 that are sequentially stored from the delivery path 22 to the rectifying basket 20 are stored in the ball tank 18 from the upstream portion of both ball passages through the ball outlet 18a of the ball tank 18. At this time, due to the weight of the game ball 16 stored in the vicinity of the ball outlet 18a, the game ball 16 stored at the upper ends of both ball paths is pushed toward the ball sensing operation members 26 and 26, and is received by each ball receiving portion 26c. Pressure is applied. As a result, as shown in FIGS. 5 and 7, the both ball sensing operation members 26, 26 have the lower ends of the ball receiving portions 26 c at the downstream of the game ball in the ball tank 18 against the urging force of the coil spring 54. The actuator lever 30b of the detection switch 30 is in a non-operating state and is set as a “ball present (off) condition”. Accordingly, the no ball signal is not input to the control device, and the notification means stops operating.

  Then, the storage ball (game ball) 16 delivered to one ball passage of the rectifying basket 20 is paid out from the payout device 14 as a prize ball, and the storage ball (game ball) 16 delivered to the other ball passage is provided. As shown in FIG. 6, for example, as shown in FIG. 6, the supply of the game balls to the ball tank 18 is stopped due to the failure of the ball replenishment facility, ball clogging, etc. When the stored ball (game ball) 16 on the one ball passage side decreases first, the ball receiving portion 26c of the corresponding ball sensing operation member 26 is released from the pressure of the stored ball (game ball) 16. Therefore, the ball sensing operation member 26 is displaced to the first position under the urging force of the coil spring 54, and the actuator lever 30b of the detection switch 30 is operated by the operation portion 26b of the member 26 to indicate “no ball ( ON) Condition ”. Accordingly, a no-ball signal from the detection switch 30 is input to the control device, and the notifying means is activated to notify the player or the pachinko hall clerk that a no-ball state has occurred. The game balls are supplied to the ball tank 18 by solving the above-described troubles of the ball replenishment equipment and the abnormal situation such as ball clogging, and the increase in the number of stored balls (game balls) 16 causes the ball sensing operation member 26 to be supplied. When the ball pressure is reapplied to the ball receiving portion 26c, the ball sensing operation member 26 swings and displaces to the second position, so that a “ball presence (off) condition” is established, and the notification means stops operating.

  Even when the storage ball (game ball) 16 on the other ball passage side decreases first, as described above, due to the displacement of the corresponding ball sensing operation member 26 from the second position to the first position, The notifying means is activated when the operation lever 26b pushes the actuator lever 30b of the detection switch 30 and a ballless signal is input to the control device. That is, in the embodiment, when the supply of the game ball is stopped in any one of the two (plural) ball paths, the operation unit 26b of the corresponding ball sensing operation member 26 presses the actuator lever 30b of the common detection switch 30. Therefore, the state of both the ball passages can be detected by one detection switch 30. Therefore, it is not necessary to provide each detection switch 30 for each ball sensing operation member 26 provided corresponding to each ball path, and the cost can be reduced.

  When the detection switch 30 has a failure such as poor contact and requires replacement work, the operation switch 60 of the mounting base member 32 extending forward from the front wall surface 42 of the ball tank 18 is held. The mounting base member 32 is pulled out from the opening 42a and extracted from the accommodation space 34 while the latching state of the locked portion 42b and the locking portion 60a is released by elastically deforming the knob piece 60. . Then, the detection switch 30 is removed from the mounting base member 32, and the new detection switch 30 is engaged with and held by the base member 32, and is set in the receiving space portion 34 from the opening 42a as described above. That is, the mounting base member 32 to which the detection switch 30 is engaged and held can be handled separately from the case member 28. Therefore, the case member in which the ball sensing operation members 26 and 26 are disposed. It is possible to easily replace the detection switch 30 without removing the 28 from the ball tank 18. Moreover, since only the detection switch 30 can be replaced, the cost required for replacement can be suppressed at a low cost.

  Moreover, since the mounting base member 32 is positioned with respect to the ball tank 18 without using fixing means such as screws, it is not necessary to tighten or loosen the fixing means, and the time required for replacement can be shortened. Can do. Furthermore, since the wiring connected to the detection switch 30 is led out from the opening 42a through which the mounting base member 32 is inserted and removed, the wiring does not interfere with the insertion and removal of the mounting base member 32. The workability is improved. When the attachment base member 32 is inserted into and removed from the accommodation space 34, the guide member 56a formed in the case member 28 guides the operation, so that the operation can be smoothly performed.
