It is arranged corresponding to each light-emitting lamp 55 of the winning opening device 15, and when a game ball enters any one of the winning openings 37, the corresponding light-emitting lamp 55 is turned on to display a number from 1 to 16. It is supposed to.

Next, the operation of the arrangement ball machine configured as described above will be described. At the start of the game, a game ball is put in the upper plate 17 and the firing handle 20 for firing is turned, the firing device 19 is activated, and the upper plate 17 is placed on the firing rail.
The game balls supplied one by one are hit with a hitting hammer, and the game balls are fired along the guide rails 6 on the upper part of the game board 5. Note that 16 game balls are used in one game. Game board
5 The game ball fired above enters the upper ball entry port 7 or the like, or enters one of the 16 winning ports 37 arranged in a row in the winning port apparatus 15. When a game ball enters the winning opening 37, after moving to the back side of the game board 5 through the guide passage 38 of the winning opening 37, the detection frame of the detection switch 26 corresponding to the guide passage 38 from the inclined plate 35. It falls on the part 58. And
When the game ball passes through the detection hole 59 of the detection switch 26, the detection switch 26 detects the game ball and the light emitting lamp 55 is lit,
The display unit 70 corresponding to the winning opening 37 in which the game ball is entered displays a numeric symbol.

If some of the 16 detection switches 26 fail, they are replaced as follows. First, the glass door 3 is opened, a pair of left and right mounting screws 69 of the lower cover 16 are removed, the positioning pins 68 are detached from the game board 5, and the lower cover 16 is removed from the game board 5. next,
The flat cable 56 attached to the connector 54 is removed, and the pair of left and right elastic locking pieces 32 of the winning case 22 are bent outward, so that the locking portion 33 of the elastic locking piece 32 and the front end face of the support member 23 are bent. The support member 23 is pulled out in the state in which the engagement with is released. Then, the substrate 24 and the detection switch 26 are separated from the winning case 22 together with the support member 23, and thereafter, of the 16 detection switches 26 inserted in the guide holes 50 of the support member 23, only the failed detection switch 26 is provided. Can be removed and another detection switch 26 inserted.

In this way, the support member 23, the substrate 24, and the detection switches 26 can be easily removed from the winning case 22 while being integrated. After the detection switches 26 are integrated with the support member 23 and removed from the winning case 22 on the game board 5 side, the detection switches 26 can be replaced, so that other components of the arrangement ball machine can be used. The replacement work of the desired detection switch 26 can be easily performed outside without being bothered. In particular, since the support member 23 is removed from the front side of the game board 5, it is not necessary to remove the winning case 22, the ball collecting case, and the like, and the support member 23 can be easily removed.

When the failed detection switch 26 is pulled backward from the guide hole 50 of the support member 23, the retaining portion 67 of the female connector 25b is disengaged, and the male connector 25a and the female connector 25b are separated from each other. Only 26 can be easily removed. For this reason, it is not necessary to replace even the failure-free detection switch 26 at the same time as compared with the conventional case using the four-unit switch, and the conventional waste can be prevented. Even when the detection switch 26 is removed from the winning case 22, the detection switch 26 is inserted into the guide hole 50 of the support member 23 and is connected to the substrate 24 via the connector 25 in a supported state, so that the failed detection switch 26 is removed. Occasionally, an unexpected external force does not greatly act on the other detection switches 26. Even if a force acts on another detection switch 26, no force other than the insertion / removal direction acts on the connection portion of the connector 25. Can be effectively prevented.

When the detection switch 26 is mounted, if the detection switch 26 is inserted and pushed into the guide hole 50 of the support member 23, the male connector 25a of the board 24 and the female connector 25b of the detection switch 26 are fitted. , The detection switch 26 can be connected easily and reliably. When the support member 23 is attached to the storage portion 27 of the winning case 22, the support member 23 is brought into contact with the inclined surfaces 33 a of the elastic locking pieces 32 on the winning case 22 side and is pushed in rearward. Since each elastic locking piece 32 is elastically deformed and expanded outward at the rear end edge of the support member 23, the support member 23 is further pushed in from that state, so that the support member
23 can be easily stored and mounted in the storage section 27. When the support member 23 is stored in the storage portion 27, the elastic locking pieces 32 are elastically restored, and the locking portions 33 are engaged with the front end surface of the support member 23. The member 23 can be securely fixed in the storage portion 27. Thereafter, the lower cover 16 may be attached.

When the support member 23 is stored in the storage portion 27 of the winning case 22, the end of each detection switch 26 comes into contact with the elastic body 49 on the case cover 40 side. It can be fixed securely in the guide hole 50 without rattling. For this reason, it is possible to prevent vibration noise caused by rattling of the detection switch 26, poor contact between the male connector 25a and the female connector 25b of the connector 25, and the like. In addition, since the board 24 side is the male connector 25a and the detection switch 26 side is the female connector 25b, the terminal board 62 of the female connector 25b may temporarily expand due to a manufacturing error, a change in diameter over a long period of use, or the like. However, there is no need to replace the substrate 24 side. In other words, the terminal board is
Since there is the female connector 25b having 62, even if the terminal plate 62 spreads and a contact failure occurs, it can be easily dealt with only by replacing the detection switch 26.

In particular, since the detection switches 26 are individually attached and detached independently of each other, only the detection switch 26 in which the terminal plate 62 has spread, that is, the failed detection switch 26 has to be replaced. It is very economical as compared with the case where the side is replaced, and the work at the time of replacement is also very easy. The present invention is not limited to the above embodiment, and the number of winning ports 37 and detection switches 26 may be more or less than 16 instead of 16. When replacing the detection switch 26, the winning case 22 may be detached from the back side of the game board 5, and then the support member 23 may be detached from the winning case 22 to replace the detection switch 26. Further, the winning case 22 may be mounted on the game board 5 from the front.

[0023]

According to the present invention, each of the detection switches 26 is individually and removably inserted into the plurality of guide holes 50 below the guide passage 38, and the front side of the guide holes 50 and the front side of the winning case 22. The detection switch 26 is detachably connected to each connector 25a on the back surface of the substrate 24 in each guide hole 50.
A plurality of display lamps 55 for displaying when the detection switch 26 detects a game ball are provided on the front surface of the substrate 24 in correspondence with each winning opening 37, so that when each detection switch 26 is replaced, a desired detection is performed. Switch 26 can be easily replaced individually,
Compared with the conventional switch using the continuous switch, it is not necessary to replace even the detection switch 26 without any trouble at the same time, so that the conventional waste can be prevented. In addition, since each detection switch 26 is detachably connected to each connector 25a on the back surface of the substrate 24 in each guide hole 50, simply inserting each detection switch 26 into each guide hole 50, the detection switch 26 is connected to the connector 25a.
It can be connected to the substrate 24 via 25a. Further, since each detection switch 26 is connected to the substrate 24 via the connector 25a in a state of being inserted and supported in the guide hole 50, a large external force does not accidentally act on each detection switch 26. Even if an external force is applied to the detection switch 26, no force other than the insertion / removal direction directly acts on the connection portion of the connector 25a, so that poor contact of the connector 25a and damage to the connection portion are effectively prevented. be able to. Also, since the detection switches 26 are arranged in two rows in the upper and lower rows, and the detection switches 26 in the other row are arranged substantially at the center of the adjacent detection switches 26 in one row, the width of the detection switches 26 is adjacent. Mouth 37
Detector switch in one row, even if larger than the gap between
26 and the detection switches 26 in the other row can be arranged so as to overlap. Therefore, the width of the winning opening device 15 can be reduced, and it is not necessary to shift the position of the detection switch 26 with respect to each winning opening 37, and each detection switch 26 can be arranged in accordance with the winning opening 37.
