Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine.

  In a ball game machine such as a pachinko machine, for example, a through-type proximity switch that detects a game ball that has won (entered) a winning entrance (entrance entrance) is provided in each winning means (entrance means). The proximity switch is configured to return a predetermined profit to the player, such as paying out a predetermined number of prize balls, based on the detection of the game ball (for example, Patent Document 1). This through-type proximity switch has a detection hole through which one regular game ball can pass, and a ring-shaped detection coil that constitutes a high-frequency oscillation circuit is embedded so as to surround the detection hole. Due to the change in impedance of the detection coil when passing through the detection hole, it is possible to detect the passage of the game ball without contact.

JP 2004-187895 A

  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. On the other hand, when placing a minimum number of radio sensors with a narrow radio detection area in order to reduce costs and reduce the possibility of false detection, all winning holes must be placed within the limited radio detection area. Therefore, there is a problem in that the degree of freedom of board layout is greatly limited.

  The present invention has been made in view of the above circumstances, and provides a ball game machine capable of maintaining a high degree of freedom in board layout in spite of being able to reduce costs and reduce the possibility of erroneous detection. With the goal.

  The present invention includes a plurality of entrances 32, 43, 46, 53, 62a to 62d provided in the game area 5a on the front side of the game board 5, and the entrances 32, 43, 46, 53, Proximity switches 34, 45, 50, 58, 64a to 64e are provided corresponding to 62a to 62d and detect game balls that have entered the entrances 32, 43, 46, 53, 62a to 62d. The proximity switch 34, 45, 50, 58, 64a to 64e is configured to return a predetermined profit to the player based on the detection of the game ball. 45, 50, 58, 64a to 64e are arranged at a predetermined position with a radio wave sensor 52 capable of detecting a radio wave of a specific frequency causing a malfunction, and the plurality of entrances 32, 43, 46, 53, 62a to 62d are Radio wave When the sensor 52 includes a detection area outside entrance 62a disposed outside the radio detection areas 59a and 59b of the sensor 52, the game balls that have entered the outside detection area entrance 62a are referred to as the radio detection areas 59a and 59b. A proximity switch 64a corresponding to the detection area outside entrance 62a at a position on the detection area guidance path 65 and in the radio wave detection areas 59a and 59b. 64e is arranged.

  Further, the radio wave sensor 52 may be disposed on the game board 5, and the detection area guide passage 65 may be disposed along the board surface of the game board 5.

  In addition, a plurality of proximity switches 64a and 64e are provided corresponding to the detection area outside entrance 62a, and all of the plurality of proximity switches 64a and 64e change from the non-detection state to the detection state within a certain period. And at least one of a plurality of proximity switches 64a and 64e corresponding to the outside-entry ball entrance 62a. May be arranged on the detection area guide passage 65 and at a position in the radio wave detection areas 59a and 59b.

  According to the present invention, since the proximity switch can be arranged at any position regardless of the position of the entrance, the cost can be reduced by arranging a minimum number of radio sensors having a narrow radio detection area. In addition, the possibility of erroneous detection can be kept low, and the degree of freedom in board layout can be maintained high.

  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.
