  Recently, this type of pachinko machine and other ball game machines have been fraudulently called “Otama Goto” using iron balls (hereinafter referred to as “illegal balls”) that are slightly larger than regular game balls. It has been confirmed in the game hall and has become a problem. The trick of this large ball is as follows. That is, first, an illegal ball is thrown into a dish and fired in the same manner as a regular game ball, and the illegal ball is forcibly awarded to a predetermined winning opening using a magnet or the like, and the proximity provided at the winning opening. The proximity switch is kept in the detection state by stopping in the detection hole of the switch. Then, the proximity switch that stops the illegal ball is irradiated with a strong radio wave of a specific frequency from outside the gaming machine, and the proximity switch is erroneously operated so as to be in a non-detection state intermittently. This is to create a detection state similar to that in the case of continuously winning.

As a countermeasure against such a fraudulent act, for example, a radio wave sensor capable of detecting a radio wave of a specific frequency used in the fraudulent act may be arranged and monitored on a game board or the like. However, it is often necessary to increase the number of radio sensors or use radio sensors with a wide radio detection area so that all winning holes in the game area fall within the radio wave detection area of the radio sensor. In general, there are problems such as high cost and high possibility of erroneous detection due to noise .

In the open state (indicated by a two-dot chain line) in FIG. It is designed to guide you. Then, a predetermined number of winning balls are paid out per winning (provided that a predetermined profit is obtained) on the condition that it is determined that a game ball has won the big winning opening 53 based on the detection signal from the proximity switch 58. Reduction).

  The radio wave sensor 52 detects a radio wave of a specific frequency that causes a malfunction of a proximity switch disposed at each winning opening. For example, both front and back sides are radio wave detection surfaces 52a and 52b. The substantially spherical areas having a predetermined radius that are in contact with 52b are radio wave detection areas 59a and 59b.

  As shown in FIGS. 2 and 5, the radio wave sensor 52 of the present embodiment is attached to the left rear part of the big prize opening unit 16 with the radio wave detection surfaces 52 a and 52 b facing left and right, and the right normal prize opening. 32, the upper starting winning port 43, the lower starting winning port 46, and the large winning port 53 are all in the radio wave detection area 59b on the right side, and correspond to the winning ports 32, 43, 46, 53. Assume that all the proximity switches 34, 45, 50, and 58 that are present exist in the radio wave detection region 59b. Therefore, any one of these right ordinary winning opening 32, upper starting winning opening 43, lower starting winning opening 46, and large winning opening 53 is set as a target of the so-called Otama Goto and corresponds to each of the winning openings 32, 43, 46, 53. When a strong radio wave is applied to the proximity switches 34, 45, 50, 58, the radio wave sensor 52 can detect the radio wave.

  The normal winning opening unit 17 is arranged along the inner side of the inner rail 12b on the left side of the large winning opening unit 16, for example, and a plurality of, for example, four first to fourth normal winning means 61a to 61a are arranged along the longitudinal direction. 61d are arranged in a line from the upper side to the lower side. The normal prize opening unit 17 is detachably attached from the front side to a normal prize opening unit attachment hole provided in the game board 5 and is fixed to the game board 5 by screwing or the like.

The first to fourth branch lines that flow into the main passage 66 with the passage 66 and the game balls that are arranged, for example, downward from the downstream end side of the rear guide passages 63a to 63d and that have won the first to fourth normal winning ports 62a to 62d. Passages 67a to 67d.

  The main passage 66 is provided with an outlet 68 at the downstream end thereof, and a first inlet 69a connected with the uppermost first branch passage 67a at the upstream end thereof. Between the inlet 69a and the outlet 68, there are formed second to fourth inlets 69b to 69d to which the second to fourth branch passages 67b to 67d are connected from the upstream side. The game balls that have won the first to fourth ordinary winning holes 62a to 62d are guided to the rear side of the game board 5 by the rear guide passages 63a to 63d, respectively, and then passed through the first to fourth ordinary winning holes 62a to 62d. It flows into the main line passage 66 and is discharged from the outlet 68.

  Further, two proximity switches, that is, an upstream primary detection switch and a downstream secondary proximity switch are provided for the first to fourth normal winning ports 62a to 62d, respectively. The proximity switches 64a to 64d are primary proximity switches individually corresponding to the first to fourth ordinary winning ports 62a to 62d, for example, inflow portions from the rear guide passages 63a to 63d to the first to fourth branch passages 67a to 67d. Is arranged. The proximity switch 64e is a secondary proximity switch common to the first to fourth normal winning ports 62a to 62d, and is disposed, for example, in the vicinity of the outlet 68 on the downstream end side of the main line passage 66.

  As a result, the game balls that have won the first to fourth normal winning holes 62a to 62d are detected by the primary proximity switches 64a to 64d corresponding to the winning holes 62a to 62d, and then the common secondary proximity switch 64e. Detected by. When it is determined that the game ball has won the first to fourth normal winning ports 62a to 62d based on the detection signals from the primary proximity switches 64a to 64d and the secondary proximity switch 64e, one winning is awarded. A predetermined number of prize balls are paid out for each (return of predetermined profit).

  As shown in FIG. 2 and FIG. 7, among the first to fourth ordinary winning openings 62a to 62d, the second to fourth ordinary winning openings 62b to 62d excluding the most upstream first ordinary winning opening 62a. Is in the radio wave detection area 59a on the left side of the radio wave sensor 52, and all of the primary proximity switches 64b to 64d corresponding to the second to fourth ordinary winning holes 62b to 62d are also present in the radio wave detection area 59a. However, the first normal winning opening (outside detection area entrance) 62a on the most upstream side is disposed outside the radio wave detection areas 59a and 59b of the radio wave sensor 52, and the corresponding primary proximity switch 64a is also used. It exists outside the radio wave detection areas 59a and 59b.

  On the other hand, the rear guide passage (detection area guide passage) 65 is arranged so as to guide the game ball won in the first normal winning opening 62a toward the inner side of the radio wave detection area 59a of the radio wave sensor 52. The secondary proximity switch 64e disposed on the guide path 65 exists in the radio wave detection area 59a. That is, among the first to fourth ordinary winning holes 62a to 62d, the corresponding primary proximity switches 64b are used for the second to fourth ordinary winning holes 62b to 62d arranged in the radio wave detection area 59a of the radio wave sensor 52. -64d and the secondary proximity switch 64e are both disposed in the radio wave detection area 59a, but the first normal winning opening 62a disposed outside the radio wave detection areas 59a and 59b of the radio wave sensor 52 is Of the corresponding primary proximity switch 64a and secondary proximity switch 64e, only the secondary proximity switch 64e is arranged in the radio wave detection region 59a.

  Next, a configuration for monitoring an illegal winning by a large ball goto etc. in the control system of the pachinko machine will be described. In the main control board 71 of this embodiment, as shown in FIG. 8, a winning processing means 72 for performing processing related to winning of game balls to each winning means 30, 41, 42, 51, 61a to 61d, and normal symbols. The symbol processing means 73 for performing processing related to symbol variation of the display means 25 and the special symbol display means 26, the accessory processing for performing processing related to the operation of the opening / closing blades 47 of the lower start winning winning means 42, the opening / closing plate 54 of the big winning means 51, etc. Means 74 are provided.

  The winning processing means 72 is based on the detection signals from the proximity switches 34, 45, 50, 58, 64a to 64e corresponding to the winning means 30, 41, 42, 51, 61a to 61d. , 42, 51, 61a to 61d, whether or not a game ball has been awarded to the winning openings 32, 43, 46, 53, 62a to 62d is determined. A winning process is executed.

For example, regarding the right normal winning means 30, the upper starting winning means 41, the lower starting winning means 42, and the big winning means 51, for example, their proximity switches 34, 45, 50, 58 are OFF.
Based on the change from (non-detection state) to ON (detection state), it is determined that a game ball has been won. For the first to fourth normal winning means 61a to 61d, for example, the primary proximity switch 64a. Based on the fact that the secondary proximity switch 64e is turned on within a predetermined time after .about.64d is turned on, it is determined that a game ball has been won.

  Further, for example, the winning processing means 72 is provided with an abnormality monitoring means 75 for monitoring an abnormality relating to the winning means 30, 41, 42, 51, 61a to 61d based on a detection signal from the radio wave sensor 52. When the radio wave sensor 52 detects a radio wave of a specific frequency that causes the proximity switch to malfunction, the abnormality monitoring unit 75 performs predetermined error processing, for example, error display on the liquid crystal display unit 21, output of an error warning sound, Processing such as error notification by an error signal output from an external output terminal, stop of payout processing, and the like is executed.

  With such a configuration, for example, when a so-called large ball goto is executed, if the target is any of the winning ports 32, 43, 46, 53, 62b to 62d other than the first normal winning port 62a, An illegal ball having a diameter larger than that of the detection hole 35 is stopped at any one of the proximity switches 34, 45, 50, 58, 64b to 64d corresponding to the proximity switches 34, 45, 50, 58, 64b. ˜64d is irradiated with strong radio waves, but the proximity switches 34, 45, 50, 58, and 64b to 64d are all in the radio wave detection areas 59a and 59b of the radio wave sensor 52, so Is detected by the radio wave sensor 52 and error processing is executed, so that damage due to large goto can be prevented in advance.

  On the other hand, even if the first normal winning opening 62a outside the radio wave detection areas 59a and 59b of the radio wave sensor 52 is the target of the large ball goto, the secondary proximity switch 64e of the first normal winning opening 62a is Since it is in the radio wave detection area 59a of the radio wave sensor 52 and is not detected by the secondary proximity switch 64e after detection by the primary proximity switch 64a, it is not determined that there has been a prize. It cannot be erroneously determined that the first normal winning opening 62a has been won, and damage due to large balls can be prevented.

  As described above, even when the winning opening 62 a is outside the radio wave detection areas 59 a and 59 b of the radio sensor 52, at least one of the proximity switches 64 a and 64 e corresponding to the winning opening 62 a is connected to the radio sensor 52. By arranging in the radio wave detection areas 59a and 59b, it is possible to avoid damage caused by large goto. Therefore, by arranging a minimum number of radio wave sensors 52 having a narrow radio wave detection area, cost can be reduced and false detection can be performed. Although the possibility can be kept low, there is an advantage that the degree of freedom of board layout can be kept high.

  FIG. 9 illustrates a second embodiment of the present invention, in which only one proximity switch corresponding to the first normal winning opening 62a, which is a detection entrance outside the detection area, is provided, and the proximity switch 64a is connected to the rear guide path (detection). An example is shown in which it is disposed on the (region guiding path) 65 and at a position in the radio wave detection area 59a of the radio wave sensor 52.

  As shown in FIG. 9, in the present embodiment, only one proximity switch 64a to 64d is provided for each of the first to fourth ordinary winning ports 62a to 62d. Further, the proximity switch 64a corresponding to the first ordinary winning opening 62a that is a detection area outside entrance is located on the back guide path (detection area guide path) 65 and in the radio wave detection area 59a of the radio wave sensor 52, that is, For example, it is arranged in the vicinity of the upstream side of the second inflow port 69b on the main line passage 66.

  As described above, when there is one proximity switch corresponding to the first normal winning opening 62a which is a ball entrance outside the detection area, the proximity switch 64a is arranged on the rear guide passage (detection area guide passage) 65. Thus, if it is provided in the radio wave detection area 59a of the radio wave sensor 52, even if the first normal winning opening 62a is a target of a large ball, the first normal winning opening while avoiding the radio wave detection by the radio wave sensor 52. It is not possible to mistakenly determine that a prize has been won for 62a, and it is possible to prevent damage caused by large balls.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the first embodiment, two proximity switches corresponding to the first normal winning opening 62 a that is a detection area outside entrance are provided, and only the proximity switch 64 e on the downstream side of them is used as the radio wave of the radio sensor 52. Although arranged in the detection area 59a, both of the two proximity switches 64a and 64e corresponding to the outside entrance of the detection area may be arranged in the radio wave detection area 59a of the radio wave sensor 52 as shown in FIG. That is, at least one of one or a plurality of proximity switches provided for the detection area outside entrance may be arranged in the radio wave detection area of the radio wave sensor.

  Further, in the first embodiment, the secondary proximity switch 64e corresponding to the first normal winning opening 62a that is a detection entrance outside the detection area is replaced with the secondary proximity of the other second to fourth normal winning openings 62b to 62d. Although the example used also as a switch was shown, as shown in FIG. 11, you may arrange | position the secondary proximity switch 64e so that it may respond | correspond only to the 1st normal winning opening 62a which is a detection area outside entrance.

  There may be a plurality of entrances outside the detection area. Further, two or more radio wave sensors 52 may be arranged, but it is desirable to keep the number to a minimum and to minimize the radio wave detection area. Further, the radio wave sensor 52 may have any specifications such as a radio wave sensor having a radio wave detection surface only on one side.

  In the embodiment, an example is shown in which the radio wave sensor 52 is arranged on the big prize opening unit 16 on the game board 5, but it may be arranged on another unit on the game board 5, and with respect to the game board 5 It may be installed directly without any other unit. Further, the radio wave sensor 52 may be disposed at a position other than the game board 5, for example, at the back side of the glass door 6, the back side of the inner frame 4, or the like.

  The winning processing means 72 may perform abnormality monitoring based on a detection signal from the proximity switch in parallel with abnormality monitoring by the radio wave sensor 52. For example, a continuous winning monitoring process for determining that there is an abnormality when a predetermined number or more of consecutive winnings are made with respect to a specific winning opening is executed, and a winning opening (for example, a first winning opening provided with a plurality of corresponding proximity switches) is executed. For the first to fourth ordinary winning ports 62a to 62d) in the embodiment, the elapsed time from the detection by the upstream primary proximity switch to the detection by the downstream secondary proximity switch exceeds a predetermined upper limit time. If it is, the detection time interval monitoring process for determining that it is abnormal may be executed.

  In addition, although pachinko gaming machine was illustrated in embodiment, it cannot be overemphasized that it can implement similarly in other ball game machines, such as an arrangement ball machine and a sparrow ball game machine.
