Description

  The present invention relates to a ball game machine such as a pachinko machine, and more particularly to a ball game machine including a vibration detector that detects vibration applied to a game board or the like.

  A pachinko machine, which is a representative example of the above-mentioned ball ball game machine, is provided with a front frame that detachably accommodates and holds the game board in a standing posture, and is provided on the rear side of the front frame so that it can be opened and closed laterally. The back set board is arranged so as to cover the back of the board, and the display unit on the front face is arranged facing the front of the gaming machine to display an image corresponding to the game development. In order to make the game development more complex by displaying various images, generally, a color image display such as a liquid crystal display panel is used to enable more dynamic image effects. The size of the display is increasing.

  On the other hand, if a pachinko machine is used for a certain period of time, the player's interest will be lost and the operating rate will decrease. In such a case, if the game board is replaced by a new table replacement operation called so-called board replacement, a relatively expensive image display will be discarded in a much shorter usage period than the original life. In terms of cost and environmental protection, it is not preferable to replace the new unit. Therefore, in recent years, a ball game machine having a configuration in which the image display can be used as it is even if the game board is replaced by providing the image display on the back set board has been proposed (see Patent Document 1). ).

  In addition, when considering the cost of replacing a new machine and the environmental protection aspect, it detects not only image display devices but also fraudulent acts (so-called goto acts) that try to win prizes and wins illegally by hitting gaming machines. It is also important that the vibration detection sensor for doing so is not wasted when the game board is replaced by a new base replacement operation.

  For example, as a pachinko machine using a so-called type 2 special electric accessory (hereinafter also referred to as a type 2 pachinko gaming machine), it has a movable wing piece (opening / closing member) that opens and closes when triggered by a winning at a start winning opening. Special equipment which has an accessory device (incoming accessory) and is advantageous to the player from the normal gaming state when the game ball taken in when the movable wing piece is released passes through a specific area in the accessory device. A so-called second type pachinko gaming machine configured to shift to a gaming state is known (see Patent Document 2). This type 2 pachinko gaming machine is provided with an accessory device in the game area, and a pair of movable wing pieces arranged on the upper left and right sides of the accessory device are opened and closed, and the game balls taken in by the movable wing pieces opened and closed Are arranged into a first passage route and a second passage route. The first passage route guides a passing game ball so that it can win a prize in either a general winning opening or a specific winning opening (so-called V zone) of a rotating body (so-called Kroon) rotating in one direction. The two passing route guides the passing game ball so that it can be dropped to a position different from the case of the first passing route (the central portion of the rotating body). The second passage route is configured to make it easier to win a specific winning opening than the first passage route.

  Such a pachinko machine described in Patent Document 2 includes a passage portion that is guided downstream of the first passage path so as to be able to win a prize in either a general winning opening or a specific winning opening of a rotating body that rotates in one direction, and the passage portion. A discharge port that is introduced to discharge the game ball that has passed through, and a human-shaped movable member that is arranged in a standing state near the passage part and the discharge port, By changing the standing state of the movable member, the state where the discharge port is blocked at the tip of the bamboo basket (restorable state) and the state where the discharge port is not blocked at the bamboo basket part (possible to stop) (Impossible state).

  By the way, in the pachinko machine described in Patent Document 2, when the movable wing piece is opened and closed by winning the start winning opening and the game ball is taken into the accessory device, for example, when it is guided to the first passage route, If the movable member is in a stoppable state where the movable member closes the discharge port when the game ball approaches the passage part, the game ball can enter the passage part and aim at the specific winning opening of the rotating body. However, on the contrary, when the game ball approaches the passage part, if the movable member is not allowed to stop without blocking the discharge port, the game ball cannot enter the passage part, It will be discharged | emitted from a discharge port through this passage part.

  Therefore, a malicious player (a fraudulent person) hits a ball tray or the like strongly in accordance with the rolling of the game ball in such a state where the player cannot stop (so-called doggy), and transmits the vibration to the accessory device itself. Then, an abnormal movement is given to the game ball that rolls and moves along the first passage route, so that the game ball is brought closer to the side of the traffic site that should normally pass. Such fraudulent acts (so-called goto acts) are performed at the timing when the specific winning opening (so-called V zone) of the rotating body approaches the passage part. You can succeed by doing it over and over again.

  As a countermeasure against such a fraudulent act, a vibration detection sensor is attached to the back side of the center ornament in the game board, and the vibration detection sensor detects the vibration given to the game board side by the cheating person hitting a ball tray etc. There is known a ball game machine configured to take a predetermined measure when it is detected in (see Patent Document 3). As this measure, for example, a subsequent game is invalidated or a warning is emitted by sound, light, display, or the like.

  In addition, the above-mentioned fraudulent acts are performed not only in the second type pachinko gaming machine but also in a pachinko machine using a so-called first type special electric machine (hereinafter also referred to as a first type pachinko gaming machine). . That is, in the first type pachinko gaming machine, many models have a center ornament in the center of the game area, and a game ball introduced from a warp introduction port provided in the center ornament has a center ornament. The so-called 100% route leads to the starting chucker below by deliberately changing the rolling trajectory of the game ball by hitting a ball tray etc. In other words, the starter chucker is forced to win a prize by striking a game ball entangled with a nail (obstacle nail) in the vicinity of the starter chuck with a ball tray or the like.

  In the same way as described above, it is possible to take measures against such an illegal act in the first type pachinko gaming machine by detecting a vibration with a vibration detection sensor and issuing a warning or the like.

  The main control board 42 includes a winning determination unit 59 and an illegal winning determination unit 60. The winning determination means 59 is configured such that the game ball launched by the game ball launching device 24 (see FIG. 4) operated by operating the launch handle 9 is used for the start chucker (specific winning portion) 14 and other winning openings (not shown). When winning a prize, it is determined that the prize has been won. The unauthorized winning determination means 60 illegally receives a winning for the starting chucker 14 based on vibration detection by the vibration detection sensor 48, winning determination for the starting chucker 14 or the like by the winning determination means 59, and human body contact detection by the contact detection sensor 36. It is determined that the prize is illegal.

  When the ball game machine according to the present invention is a so-called second type pachinko game machine, the specific winning portion is a center decoration as a ball-winning accessory disposed substantially at the center of the game area PA. It corresponds to a V winning opening (so-called V zone) of a rotating body (not shown) provided in (not shown), and the winning determination means 59 determines whether or not there is a winning in the V winning opening. The unauthorized prize determination means 60 determines the prize to the V prize opening based on the vibration detection by the vibration detection sensor 48, the prize determination to the V prize opening by the prize determination means 59, and the human body contact detection by the contact detection sensor 36. It is determined that the prize is illegal due to fraud.

  In the pachinko machine PM having the above-described configuration, the vibration detection sensor 48 held by the holding unit 40 on the game board 10 side in the state of being installed in the game hall when the board surface is changed by replacing a new table or the like, When the vibration detection sensor 48 is pulled away from the holding portion 40 while placing a finger or the like on the 40d to slightly lift the claw portion 40b outward, the claw portion 40b is disengaged from the engagement recess 48c, and the vibration detection sensor 48 is detached from the holding portion 40.

The vibration detection sensor 48 is temporarily fixed to the temporary fixing portion 47 side with the front end surface 48d leaving a slight gap from the transparent cover 46.

  In this state, after the old version of the game board 10 with the effect control board 44 and the main control board 42 mounted on the decorative board 11 is removed from the back set board 30 side, a new game board 10 to be replaced is placed on the back set board. Attach to 30 side. Thereafter, the vibration detection sensor 48 temporarily fixed to the temporary fixing portion 47 is removed by pulling from the temporary fixing portion 47, and the vibration detection sensor 48 is brought close to the holding portion 40 by manually passing the surrounding gap. The vibration detection sensor 48 is pushed into the holding part 40, and the front end face 48 d is fixed to the holding part 40 in a state of being in close contact with the back side of the decorative plate 11.

  In the present embodiment described above, the vibration detection sensor 48 capable of detecting vibrations that act on the game board 10 and exceeding a predetermined reference value, and the vibration detection sensor 48 is held at a contact position where the vibration detection sensor 48 contacts the back side of the game board 10. A state changing means comprising a holding portion 40 and a temporary fixing portion 47 that can be changed to a first state in which the vibration detecting sensor 48 is held and a second state in which the vibration detecting sensor 48 is held in either the front frame 2 or the back set panel 30. With. As a result, the vibration detection sensor 48 is not mounted on the game board 10 that is the replacement target, but is connected to the payout control board 43 on the back side of the game board 10 that is not the replacement target. When the replaced game board 10 is held in the temporary fixing portion 47 and set to the front frame 2, the vibration applied to the game board 10 can be properly detected. For this reason, as before, when the board is changed by replacing a new table, the problem that the vibration detection sensor 48 is disposable every game board to be replaced can be solved. The “contact position” means a position at which the vibration detection sensor 48 is brought into contact with the back side of the game board 10 and vibration detection by the vibration detection sensor 48 is possible.

  Further, in the present embodiment, the state changing means includes the holding unit 40 that holds the vibration detection sensor 48 in a state of being inserted and fixed and brought into contact with the back side of the game board 10, the front frame 2, and the back set board 30. It consists of a temporary fixing portion 47 that is disposed on either side and can temporarily hold the vibration detection sensor 48 removed from the holding portion 40. For this reason, when changing the surface of the board, the vibration detection sensor 48 removed from the holding part 40 is temporarily fixed and held in the temporary fixing part 47, and the gaming board 10 is replaced with a new one in that state, and then temporarily fixed. The vibration detection sensor 48 removed from the portion 47 is inserted and held in the holding portion 40 provided in the new game board 10 so that the vibration detection sensor 48 can be attached very easily.

  Further, according to the present embodiment, the main control board 42 that comprehensively controls the operation of the pachinko machine PM, the liquid crystal display panel 50 having the display unit 55, and the image control signal to the liquid crystal display panel 50 based on the effect command signal. And an effect control board 44 that displays an image according to game development on the display unit 55, and a payout control board 43 that controls the operation of the ball payout device 34 based on a payout command signal from the main control board 42. The vibration detection sensor 48 is electrically connected to the payout control board 43. For this reason, the vibration detection signal from the vibration detection sensor 48 can be output to the main control board 42, and the vibration detection signal is sent to the effect control board 44 via the main control board 42 so that an illegal act is performed. A screen that can be suppressed can be displayed.

  Further, according to the present embodiment, the main control board 42 and the effect control board 44 are located in the lower rear region of the game board 10 below the surrounding decorative frame (window) 15b and above the lower end face of the game board 10. Since it is disposed so as to overlap the lower area of the rear surface of the game board 10 in the front-rear direction, when the game board 10 is attached and detached by replacing a new table, the main control board 42 unique to the game board 10 and The effect control board 44 can be replaced integrally, and workability is further improved. Since the production control board 44 is located in the lower rear area of the game board 10, the liquid crystal display panel 50 is arranged at the rearmost part of the back set board 30, and a deep game area is formed in front of the liquid crystal display panel 50. Can be secured.

  According to the present embodiment, the contact detection sensor 36 is arranged on the upper ball tray 8a of the gaming machine main body to detect the presence or absence of human contact, and the winning determination means 59 is a specific prize arranged in the game area PA. Judgment of winning a prize to a part (the starter chucker 14 in the present embodiment in which the present invention is applied to a so-called first type pachinko gaming machine, and the V prize opening in the case where the present invention is applied to a so-called second type pachinko gaming machine) Then, the illegal prize determination means 60 is based on the vibration detection by the vibration detection sensor 48, the winning determination to the specific winning part by the winning determination means 59, and the human body contact detection by the contact detection means 36, and the prize winning to the specific winning part is determined. Is determined to be an illegal prize for fraud. As a result, when a prize is awarded to the specific prize winning section, it is easily specified that the prize has been acquired by a so-called fraudulent act regardless of whether or not the game staff is actually looking at the site. can do.

  Then, the unauthorized winning determination means 60 performs the above-mentioned identification on condition that the human body contact detection by the contact detection sensor 36 disposed in the upper ball tray 8a is performed in addition to the vibration detection by the vibration detection sensor 48 and the winning determination by the winning determination means 59. The winning in the winning section is determined as an illegal winning. As a result, when a legitimate prize winning in the specific prize winning section was obtained with its own pachinko machine PM (this machine), the vibration caused by the doppling performed on the adjacent pachinko machine (other machine) was transmitted to this machine. However, if contact with a hittable part (that is, contact with a human body) is not detected with this machine, it will not be knocked. Therefore, the specific prize on the machine side is determined as an illegal prize. There is nothing. In this way, the player who is playing with this machine has obtained a prize for the above-mentioned specific winning part, but the specific prize becomes invalid due to the influence of the vibration caused by the adjacent pachinko machine, etc. The occurrence of unreasonable events can be reliably avoided. It goes without saying that these configurations can be similarly applied to Modifications 1 and 2 described later.

  In the present embodiment, the temporary fixing portion 47 is provided on the transparent cover 46 disposed on the front frame 2 side. However, the present invention is not limited to this, and appropriate portions and other portions in the front frame 2, the back set board 30. It can also be provided at an appropriate part or other part, or a part extended from the front frame 2 or the back set board 30 by a support member or the like, and in that case, the same effect can be obtained. This also applies to Modifications 1 and 2 described later.

  Next, with reference to FIG. 11, the modification 1 of this embodiment is demonstrated.

  That is, as shown in FIG. 11, the holding portion 56 and the temporary fixing portion 57 of the front frame 2 in a state where the game board 10 is mounted on the front frame 2 and the back set board 30 is attached to the front frame 2. It is provided so as to be aligned in the front-rear direction (left-right direction in FIG. 11). That is, when the back set board 30 is attached to the front frame 2 in a state where the temporary fixing part 57 is supported on the back set board 30 side via the support member 54, the back of the holding part 56 on the back side of the decorative board 11. It abuts in a state of being aligned with the side (meaning the side opposite to the side where the player who is playing facing the game area PA is located). Thus, the holding part 56 fixed to the back side of the decorative board 11 of the game board 10 via the L-shaped member 39 and the rear side of the holding part 56 having the same cross-sectional shape and size. A temporary fixing portion 57 supported on the back set panel 30 side via a support member 54 so as to be in close contact with the front frame 2 is provided so as to be aligned in the front-rear direction of the front frame 2. Reference numeral 54 a is an opening formed in accordance with the rear opening formed by the inner surface 57 a of the temporary fixing portion 57.

  Unlike the temporary fixing portion 47 shown in FIG. 9, the temporary fixing portion 57 in the first modification does not have a claw portion like the claw portion 47 b, and is a vibration inserted from the rear side (the right side in FIG. 11). In a state where the detection sensor 48 is temporarily fixed and held (see FIG. 11A), a claw portion (locking portion) 57b that protrudes toward the front end surface 48d of the vibration detection sensor 48 is provided. The claw portion 57b is configured to have an urging force inward when pressed outward by an elastic thin portion 57c that is formed thinner than the other portion and has elasticity. When the vibration detection sensor 48 is inserted in the direction of arrow A, the tip of the claw portion 57b is pushed up by the chamfer 48b and bent outward along the outer peripheral surface 48a (FIG. 11B). When the claw portion 57b passes through the claw portion 57b and is inserted into the inner surface 56a side of the holding portion 56, the claw portion 57b is detached from the outer peripheral surface 48a and rotated in the direction of arrow B to return to the original state. The vibration detection sensor 48 is held in contact with the rear end surface 48e of the vibration detection sensor 48 so as not to come out of the holding portion 56 (see FIG. 11C). Thereby, the vibration detection sensor 48 is in a state in which the applied vibration can be properly detected in a form in which the front end surface 48d is brought into contact (contact) with the back surface 11a side of the decorative plate 11.

  On the other hand, when removing the vibration detection sensor 48 from the holding portion 56 when replacing a new base, etc., a finger or the like is hung on the finger hook portion 57d on the upper portion of the claw portion 57b, and the harness 49 is gently pulled in that state. The holding portion 56 is moved to the temporary fixing portion 57 side and is held (temporarily fixed) to the temporary fixing portion 57. In this state, when the board surface is changed, and then a new game board 10 is set, the temporary fixing part 57 side aligned with the holding part 56 on the back side of the decorative board 11 of the game board 10 is used from the temporary fixing part 57 side.
