For example, it is electrically connected to the main control board side.
[0040]
In the arrangement ball machine having the above-described configuration, when the player grasps the operation handle 21 of the launching means 14 and rotates it, the firing motor 19 is actuated, and the striking rod 17 is intermittently swung. With a striking force corresponding to the spring pressure, the game ball at the launch position A on the launch rail 16 is hit with the tip of the hitting rod 17 and fired to the guide rail 23 side of the game board 12.
[0041]
When the game ball on the launch rail 16 is hit and fired by the batting rod 17, the ball feeding means 15 operates in conjunction with the batting operation of the batting rod 17, and game balls from the upper plate 7 are one by one. Feed on firing rail 16.
[0042]
When the ball feeding means 15 supplies the game ball onto the firing rail 16, the game ball moves to the stopper 64 side along the firing rail 16, and the upper end side thereof abuts on the ball restricting portion 74 of the stopper 64, so that the firing position is reached. A is positioned. When the game ball comes into contact with the stopper 64 at the launch position A, the detection switch 65 detects the game ball through the detection opening 78a. Then, after the detection switch 65 detects the game ball, when the batting rod 17 strikes and fires the game ball, the detection state of the detection switch 65 changes to a non-detection state, and the release of the game ball is detected. The For example, the counting means on the main control board side adds 1 to the number of shots based on the detection signal from the detection switch 65 and counts the number of shots for each game.
[0043]
Normally, most of the game balls move along the guide rail 23 to the upper side of the game board 12, enter the game area 24 from the upper end side of the guide rail 23, and then enter the game board 12 while colliding with game nails and the like. Fall down along.
[0044]
However, when the launch force is weak and the game ball stalls in the middle of the guide rail 23, the game ball becomes a foul ball and returns to the upstream side along the guide rail 23, and passes through the foul ball guide passage 44. Go back to plate 9. When the foul ball passes through the foul ball guide passage 44 and the foul ball detection switch 44a detects the foul ball, the counting means subtracts 1 from the number of shots in the game. Thereby, the number of shots counted by the counting means is the actual number of shots actually driven into the game area 24.
[0045]
As described above, in the present embodiment, since the stopper 64 and the switch holding portion 66 that holds the detection switch 65 are integrally formed, for example, the stopper 64 and the detection switch 65 can be attached at a time. Assembling work can be performed very easily, and workability is remarkably improved. In addition, since the relative positional relationship between the stopper 64 and the detection switch 65 is always constant, the positional relationship between the game ball at the firing position A and the detection switch 65 is also constant, so that accurate firing detection can always be performed. There is also.
[0046]
In addition, the launch position member 48 and the launch rail 16 integrally provided with the stopper 64 and the switch holding portion 66 are both attached to a predetermined position on the gaming machine main body side, for example, the front side of the support plate 13 via the attachment plate 49. Therefore, the relative positions of the firing rail 16, the stopper 64, and the detection switch 65 are always kept constant via the mounting plate 49, and the relative position between the firing rail 16, the stopper 64, and the detection switch 65 is prevented. And more accurate launch detection can be performed.
[0047]
The switch holding portion 66 is provided downstream of the stopper 64 in the firing direction, and the detection switch 65 attached to the switch holding portion 66 is arranged substantially above the game ball positioned at the firing position A, and Since the detection opening 78a is provided between the game ball positioned at the launch position A and the detection switch 65 held by the switch holding unit 66, the game ball is detected via a synthetic resin closing plate, for example. Compared to conventional ball game machines, the possibility of malfunction is low, and there is an advantage that the reliability of counting the number of shots is improved.
[0048]
Since the inclined guide part 78c for guiding the game ball onto the launch rail 16 is provided on the downstream side in the firing direction of the switch holding part 66, the switch holding part 66 is not only used as a holding member for the detection switch 65 but also for the game ball. It can also be used effectively as a guide member.
[0049]
An attachment / detachment opening 76 for attaching / detaching the detection switch 65 to / from the switch holding unit 66 in the front / rear direction is provided on the rear side of the switch holding unit 66, and the detection switch 65 is provided in the front / rear direction from the back side of the switch holding unit 66. The detection switch 65 can be easily attached and detached, and the rear side of the detection switch 65 is closed by closing the attachment / detachment opening 76 from the back side by attaching the firing position member 48 to the front side of the support plate 13 or the like. The movement to can be easily controlled.
[0050]
Further, since the front side of the switch holding portion 66 is provided with engagement protrusions 79a to 79c that engage with the detection switch 65 side and restrict the movement of the detection switch 65 in the direction orthogonal to the firing rail 16, The distance between the detection switch 65 and the game ball at the launch position A can be easily and reliably set to a predetermined value simply by inserting the detection switch 65 into the switch holding portion 66 through the attachment / detachment opening 76.
[0051]
As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the switch holding portion 66 may be integrated with the stopper 64. For example, the switch holding portion 66 is disposed on the back side of the back plate portion 63, and the detection switch 65 is moved to the front firing position A via the back plate portion 63. You may comprise so that a certain game ball may be detected.
[0052]
When holding the detection switch 65 on the downstream side of the stopper 64, the switch holding unit 66 desirably holds the detection switch 65 in a direction orthogonal to the firing rail 16 as in the embodiment. For example, it may be held in a direction other than the direction orthogonal to the firing rail 16.
[0053]
The detection switch 65 may be attached / detached in the front / rear direction from the back side of the switch holding unit 66, for example, or may be attached / removed in the front / rear direction from the front side of the switch holding unit 66. You may comprise so that it may be attached or detached.
[0054]
When attaching / detaching the detection switch 65 in the front-rear direction from the back side of the switch holding portion 66 as in the embodiment, a restricting member for restricting the movement of the detection switch 65 to the rear side may be provided integrally with the firing position member 48, for example. Good.
[0055]
As a means for restricting the movement of the detection switch 65 in a predetermined direction, for example, an engagement protrusion is provided on the detection switch 65 side, and the engagement protrusion is engaged with an engagement groove or the like on the switch holding portion 66 side. May be. In addition, no engagement groove or engagement protrusion is provided on the detection switch 65 side, and for example, the engagement protrusion on the switch holding portion 66 side is engaged with, for example, the upper and lower surface sides on the detection switch 65 side, and the detection switch 65 has a predetermined direction. You may make it regulate the movement to.
[0056]
The firing position member 48 may be configured to be always fixed with a fixed relative positional relationship with respect to the mounting plate 49 side. For example, the number of positioning protrusions 70 may be one.
[0057]
The detection switch 65 may be any proximity switch that can detect a steel game ball without contact, and various proximity switches such as a magnetic sensitive type, an inductive type, and a capacitance type can be used.
[0058]
Furthermore, in the embodiment, the arrangement ball machine has been described as an example. However, in addition to other combination type ball game machines such as a sparrow ball game machine, the same configuration is also applied to various ball game machines such as a pachinko machine. Can be adopted. In the case of a pachinko machine, control is not performed to fire a predetermined number of game balls for each game, but detection signals from the detection switch 65 and the foul ball detection switch 44a are not used for controlling the launching means 14, for example. Is possible. For example, in the case of a ball-circulating pachinko machine, it is necessary to subtract the amount corresponding to the number of effective shots from the card. Therefore, the detection signal from the detection switch 65 or the foul ball detection switch 44a is used for counting the number of effective shots. it can.
