BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game ball detecting device for a ball game machine such as a pachinko machine.

[0002]

2. Description of the Related Art In a pachinko machine, in addition to obstacle nails, various game parts such as a ball entrance and a prize winning device are arranged on the front of a game board, and a detector for detecting the entry of a game ball into the game parts. In the game, after guiding the game ball fired from the firing device to the upper part of the game board via the rail, the game ball is dropped from the upper part, and the game ball enters the game part during the fall Then, it is detected by a detector, and a predetermined game ball is paid out as a prize ball by a prize ball payout device.
Conventionally, in this type of pachinko machine, a detection element is incorporated at one end in a rectangular detector main body so as to be close to a fall passage in a game component, and a drop passage side of the detector main body is provided.
A detector having a gate-shaped guide frame integrally including a pair of left and right guide portions projecting from the detector body and a tip guide portion connecting left and right between the tips of the left and right guide portions is used. There is a game device in which a detector is incorporated in a game component such that an inner space of the frame coincides with a fall path, and a game ball falling in the fall path is guided by a guide frame and detected by a detection element.

[0003]

In the conventional detector, a gate-shaped guide frame comprising left and right guides and a distal end guide is integrally provided on the side of the fall passage of the detector main body. Since the length is large, when this detector is incorporated in a game component such as a winning device, the size of the game component is disadvantageously increased. That is, a gate-shaped guide frame including a left and right guide portion and a tip guide portion is provided integrally with the detector main body, and a game ball passing through the internal space is guided by the left and right guide portions and the tip guide portion of the guide frame. Therefore, the guide frame protrudes largely forward from the detector main body. Therefore, when incorporating the detector into the game component such that the inner space of the guide frame coincides with the fall path, it is necessary to provide a recess in the passage wall in front of the fall path of the game component so that the leading end guide portion of the guide frame can be accommodated. In this case, the passage wall on the front side of the game component projects greatly forward, and the size of the game component increases.

However, there is a glass door on the front side of the game board, and the distance between the game board and the glass door is substantially constant.
There is a problem that the glass door comes into contact with the game component, and it is difficult to increase the protruding amount without limit. The guide frame has a gate shape so as to surround the fall path, so the width in the left-right direction is also large.However, since the width of the main body of the detector is conventionally set to the same width as the guide frame, the guide frame is The width of the detector mounting portion also becomes large, and it is difficult to integrate a plurality of detectors into various small game components at high density for various functions.

In addition, since the detector frame of the detector has a guide frame, and the guide frame surrounds a fall path corresponding to the detector, the front side of the game component temporarily corresponds to the detector. Even if the opening is provided, a part of the guide frame blocks the opening at the front side of the falling path, so that the player cannot visually check the game ball at the time of detection by the detector from the front. In view of such conventional problems, the present invention can reduce the size of the detector and the size of the game component, and in particular, reduce the size of the game component in the longitudinal direction of the detector, and reliably detect the game ball by the detector. It is an object of the present invention to provide a game ball detection device for a ball game machine that can perform the game.

Damage due to wear or the like of the 48 itself can be reduced, and the durability of the detector 22 is significantly improved. In addition, since each guide projection 48 of the detector 22 is shorter than the radius of the game ball B, the length and width of the detector 22 are smaller than those having the conventional gate-shaped guide frame, and The device 12 can be downsized.

That is, the detector 22 has a pair of left and right guide projections 48 projecting from the left and right sides of the detection element 44 toward the drop passage 34.
And the guide projections 48 are made shorter than the diameter of the game ball B, and the front ends of the guide projections 48 are formed in an open state. , The length of the detector 22 can be shortened accordingly. The pair of left and right guide projections 48 is shorter than the diameter of the game ball B so that the tip of the two guide projections 48 is open, while the game ball B at the detection position is opposite to the detector main body 42. Side to detect the game ball B
Since the inclined guide portion 53 for guiding to the side is provided on the intermediate partition 25 side of the winning case 23 of the lower winning device 12, the game ball is not included in the detector 22 itself even though there is no portion passing through the front side of the game ball B. B can be reliably guided to the detection element 44 side.
, The game ball B can be reliably detected.

In addition, a pair of left and right guide projections 48

Is provided on the intermediate partition 25 side of the winning case 23, so that the amount of protrusion of the lower winning device 12 on the winning case 23 side is smaller than in the conventional case using a detector having a guide frame having a leading end guide portion. it can. Further, since the length of the guide projection 48 is shorter than the radius of the game ball B, the dimension between the outer sides of the pair of left and right guide projections 48 can be made smaller than that in which the game ball B is guided on both left and right sides in the diameter direction. Therefore, the width of the detector 22 is reduced. For this reason, the dimension between the pair of mounting portions 46 of the mounting plate 24 can be reduced, and for example, a design in which a plurality of detectors 22 are arranged close to each other and at a high density is sufficiently possible.

Further, a pair of left and right guide projections of the detector 22 are provided.
An inclined guide surface 49 is provided on 48, and while the inclined guide surface 49 prevents misalignment of the game ball B from the left and right with respect to the detection element 44,
Since the guide portion 50 of the intermediate partition 25 has a function of guiding the game ball B to the detector 22 side, as shown in FIG. 7, the shape and structure of the guide portion 50 on the intermediate partition 25 side can be simplified. It is possible to Therefore, even when the winning case 23 is formed by an injection molding method or the like using a synthetic resin material, there is an advantage that the mold structure on the winning case 23 side can be simplified.
In the embodiment, the case where the detector 22 is incorporated in the lower winning device 12 is illustrated, but the present invention is not limited to this embodiment. For example, game parts into which the detector 22 is to be incorporated include other entrances 7 to 10 and winning devices 13 and 14.
Etc., and the shape and structure of the drop passage 34,
Alternatively, the location where the detector 22 is provided can be variously changed according to the function of the game component. Further, the see-through unit 31
May be constituted by notches or openings as in the embodiment, or may be constituted by making the wall of the game component itself transparent. The detection element 44 is a non-contact game ball
It only needs to be able to detect B, and its detection principle does not matter. Of course, the present invention can be similarly applied to various ball game machines other than pachinko machines.
