Description

  The present invention relates to a gaming machine in which a game ball paid out from a ball payout device is guided to a ball tray mounted on the front surface.

  Conventionally, a pachinko gaming machine, which is a kind of gaming machine, is mounted with a main body frame having a game board disposed on the front surface of the machine frame, and a transparent plate as a front cover frame body covering the front surface of the game board on the front surface of the main body frame. A holding frame is pivotally mounted so as to be openable and closable, and a front plate as a front cover frame that covers the lower portion of the game board is pivotally mounted below the transparent plate holding frame so as to be openable and closable. A ball tray for storing game balls to be supplied to the hitting ball launch position is mounted on the front surface of the front plate. In addition, a mechanism plate is mounted on the back side of the main body frame, and a predetermined amount of game balls supplied from the ball tank together with the ball tank are provided on the back side of the mechanism plate, for example, when a winning ball is generated or a rental ball payout request When there is, a ball payout device is provided. Below the ball payout device, there is provided a ball discharge rod for guiding the game balls paid out from the ball payout device to the ball tray on the front surface of the front plate. The discharge port at the lower end of the ball discharge basket faces forward. And when a front board is obstruct | occluded by the front surface of a main body frame, this discharge port is connected to a ball receiving tray via a front board.

  Furthermore, for example, when the front plate is opened for a fault check while the game ball stays continuously from the ball tray to the ball discharge basket, the game ball remaining in the ball discharge basket is discharged at the lower end. A shutter mechanism is provided on the front surface of the main body frame in order to prevent spilling downward from the outlet. More specifically, the shutter mechanism has a shutter plate that opens the discharge port when the front plate is closed and closes the discharge port when the front plate is opened (see, for example, Patent Document 1).

Japanese Patent No. 3938692 (page 6-9, FIGS. 1 to 8)

  However, in the pachinko gaming machine according to Patent Document 1, when the front plate is opened without knowing that the game ball remains in the ball discharge basket, the discharge port of the ball discharge basket is closed with the shutter plate. Although the game ball is prevented from spilling unnecessarily from the exit, it is difficult to instantly close the outlet when the front plate is opened due to the large outlet. For this reason, when the front plate is actually opened, several game balls spill out from the outlet.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine that prevents the ball of the game ball from spilling and prevents the ball from biting when the front cover frame is opened. It is what.

  In order to achieve this object, the gaming machine of the present invention has a front cover frame that is pivotally mounted on the front surface of a main body frame that is mounted on the machine frame so that the front cover frame can be opened and closed. A gaming machine having a ball tray in which game balls guided and discharged by a discharge basket are stored, wherein the main body frame is opened when an upper surface is released from the ball tray and the front cover frame is closed. A tray portion that protrudes to the rear side, and a discharge port that faces the top surface of the tray portion when the front cover frame is closed on the bottom surface of the downstream end portion of the ball discharge rod; It slides horizontally between the discharge port and the upper surface of the saucer part, and is always urged to one side by an elastic member and retracted by being pushed by the saucer part when the front cover frame is closed. When the discharge port is opened and the front cover frame is opened, the front is moved forward by the urging of the elastic member. A shutter plate that closes the discharge port is disposed, the width of the discharge port of the ball discharge rod in the direction in which the shutter plate slides is the diameter of the game ball, and the downstream end of the ball discharge rod When the shutter plate moves forward, the game ball located between the tray and the downstream end of the ball discharge rod is pushed out to the outside by the forward moving shutter plate in a position facing the tip of the shutter plate. A notch recess is provided, and a retreat space having a predetermined width is provided on the outside of the notch recess in the tray portion so that the game ball pushed out from the notch recess stays.

  In the gaming machine according to the present invention, when the upper surface is released to the ball tray and the front cover frame is closed, a tray portion that protrudes to the rear side of the main body frame is extended to the front surface of the downstream end portion of the ball discharge basket. When the cover frame is closed, a discharge port that faces the upper surface of the tray part is formed, and it slides horizontally between the discharge port of the ball discharge basket and the upper surface of the tray part and is always biased to one side by an elastic member. When the front cover frame is closed, a shutter plate is arranged to retreat by being pushed by the tray and open the discharge port, and when the front cover frame is opened, move forward by the elastic member to close the discharge port. The width of the discharge port of the ball discharge rod in the direction in which the shutter plate slides is made the diameter of the game ball, and the downstream end of the ball discharge rod faces the tip when the shutter plate advances. The shutter plate which advances the game ball in communication with the discharge port at a position thereof Opened cutout recess to push to the side, is provided with a retraction space of a predetermined size of the game ball pushed out of notch recesses on the outside of the cutout recess stays at saucer section. Therefore, when the front cover frame is opened, the shutter plate closes the discharge port as the tray portion moves away from the discharge port at the downstream end of the ball discharge rod, and the game ball stays in the ball discharge rod. Even if the front cover frame is opened in this state, the game ball pushed by the shutter plate is pushed out to the outside through the notch recess, and is received in the retreat space located outside thereof.

  Therefore, since the sliding stroke of the shutter plate can be set to the minimum necessary size, not only the ball spills from the discharge port, but also the ball biting does not occur at all, and the ball discharge basket and ball tray are damaged. The front cover frame can be opened and closed safely. Furthermore, since the game ball pushed out from the notch recess remains in the tray part as it is and does not fall below the gaming machine, there is a beneficial effect that the player is not disadvantaged.

  Hereinafter, embodiments of a gaming machine according to the present invention will be described in detail with reference to the drawings. The present invention is applied to a pachinko gaming machine, an arrangement ball machine, a sparrow ball machine, a pachislot machine, etc. that use a game ball as a game medium. Among these, the present invention is applied to a pachinko gaming machine. A description will be given of the case.

  FIG. 1 is a front view of a pachinko gaming machine according to the present invention, FIG. 2 is a perspective view of the state where the transparent plate holding frame and the front plate are opened, and FIG. 3 is a rear view thereof. The pachinko gaming machine P includes a vertically long rectangular machine casing 1, a main body frame 2 is mounted on the front side of the machine casing 1, and a game board 3 is disposed on the main body frame 2. Further, the front frame of the main body frame 2 has a transparent window 5 that covers the upper front surface of the game board 3 and is covered with a transparent plate 4 so that the front surface of the game board 3 can be seen from the front side. A plate holding frame 6 is mounted so as to be freely opened and closed. A front plate 7 as a front cover frame that covers the lower front surface of the game board 3 is mounted below the transparent plate holding frame 6 so as to be freely opened and closed. On the front surface of the front plate 7, a ball tray 8 for storing a game ball supplied to a hitting ball launching position 20, which will be described later, is mounted. At one side of the ball receiving tray 8, a hitting force adjusting handle 9 for adjusting the hitting force of the game ball supplied to the hitting ball launch position 20 is attached.

  Here, although the transparent plate holding frame 6 and the front plate 7 are shown as the front cover frame body, the transparent plate holding frame and the front plate are integrated with each other, and a sphere is formed on the front surface thereof. What was equipped with the ball receiving tray which stores the game ball discharged | emitted from the payout apparatus may be used. In addition, it is also possible to see that the ball tray itself is mounted instead of the front plate. In such a case, the ball tray serves as the front cover frame.

  Inner and outer guide rails 10a and 10b are laid in a substantially spiral shape on the surface of the game board 3, and a gaming portion 3a is formed so as to be surrounded by the inner and outer guide rails 10a and 10b. In the game unit 3a, a large variable display device 11 is arranged near one side of the upper half. In addition, a start winning opening 13 having a pair of opening and closing blade pieces 12 and 12 is disposed below, and further, a large winning device 14 having an opening and closing door 14a that is freely opened and closed to the front side is disposed below. An out ball opening 15 is provided on the inner side of the inner guide rail 10a at the lower end of the game unit 3a to discharge a game ball that has been driven into the game unit 3a and flowed down but could not be won to the outside of the pachinko gaming machine P as an out ball. It has been.

  A ball storage portion 8a for storing game balls is provided in the ball tray 8 on the front surface of the front plate 7, and a tray portion 16 that protrudes substantially horizontally rearward is integrally provided at the rear end edge of one side thereof. The tray 16 is open at the top and protrudes to the rear side of the main body frame 2 when the front plate 7 is closed. Further, on the rear surface of the front plate 7, there is provided a hitting ball supply device 17 for supplying game balls one by one to the hitting position 20 of the launch rail 19 described later in the center, and without being driven into the game section 3a on one side thereof. A ball receiving member 18 for receiving and processing the returned foul ball is disposed.

  A launch rail 19 is attached to the lower front surface of the main body frame 2 corresponding to the front plate 7 so as to correspond to the hitting ball supply device 17, and the tip side is inclined upward so as to be connected to the outer guide rail 10b. An electromagnetic solenoid 21 for hitting a game ball supplied to a hit ball launching position 20 at the base end of the launch rail 19 is mounted on the base end side. On the other side of the firing rail 19 and on the side of the main body frame 2, a through hole 22 is formed through which the tray 16 extending rearward from the rear edge of the ball tray 8 is inserted.

  A ball tank 25 for storing game balls is provided on the upper surface of the back surface of the main body frame 2, and a tank rail 26 for guiding game balls discharged from the ball tank 25 downstream is provided below the tank tank 25. A ball payout device 28 is disposed at the downstream end of the rail 26 via a curve rail 27. Below the ball payout device 28, a ball discharge rod 29 for guiding the game balls discharged from the ball payout device 28 to the ball receiving tray 8 is disposed. At the downstream end of the ball discharge rod 29, a vertical vertical rod portion 30 is continuously formed. And when the said front plate 7 is closed, the discharge port 31 of this vertical hook part 30 lower end faces the said saucer part 16 upper direction.

  Therefore, the game balls stored in the ball storage portion 8a of the ball tray 8 are supplied one by one to the hitting position of the hitting rail 19 from the hitting ball supply device 17 and are launched by the electromagnetic solenoids 21, respectively. The launched game ball is guided to a ball guide path 32 formed between the inner and outer guide rails 10a and 10b and discharged from the upper end thereof to the game unit 3a.

  When the game ball released to the game unit 3a wins the start winning opening 13, symbols such as numbers and symbols displayed on the display 11a of the variable display device 11 start to change, and stop after a certain time has passed. At this time, when the stopped symbols are aligned with a specific symbol such as “777”, for example, a special game state advantageous to the player, so-called “big hit” is obtained. In this state, the open / close door 14a of the large winning device 14 is rotated forward, and is opened, for example, until ten game balls are won or for 30 seconds. Further, this is repeated as many as 16 rounds as long as a certain condition is continued as one round. When a winning ball is generated, a predetermined amount of game balls are discharged from a ball payout device 28 provided on the rear side of the mechanism plate 23 to a ball discharge basket 29. The discharged game ball falls from the vertical saddle portion 30 at the lower end of the flow to the tray 16 and is stored in the ball tray 8 on the front surface of the front plate 7.

  In the present invention, as shown in FIGS. 4 to 6, the shutter mechanism 33 is disposed behind the main body frame 2 and above the tray 16. When the front plate 7 is inadvertently opened while the game ball stays in the ball discharge basket 29, the shutter mechanism 33 allows the game ball to be released from the discharge port 31 at the lower end of the vertical hook portion 30 of the ball discharge basket 29. This prevents the spilling downward. This is because if a game ball spills, the player loses the game ball that is earned by the player, resulting in a loss to the player.

  The shutter mechanism 33 has the following configuration. That is, a holding plate 35 is provided which is supported by a pair of guide bars 34, 34 disposed on the back surface of the main body frame 2 in a horizontal and parallel manner, and slides left and right along the pair of guide bars 34, 34. . The holding plate 35 has a substantially U-shaped cross section and has a horizontally elongated hole 36 in the center along the longitudinal direction. Two bosses 37, 37 that are loosely fitted in the laterally long holes 36 and protrude rearward are provided on the back surface of the main body frame 2, and screw holes 38 are formed at the rear ends of the bosses 37.

  Then, a support piece 39 wider than the groove width of the laterally long hole 36 is applied to the rear ends of the bosses 37, 37, and the screw insertion holes 40, 40 provided in the support piece 39 are inserted into the screw holes of the bosses 37. 38. Furthermore, the upper and lower bent pieces 35a, 35a of the holding plate 35 are supported by the guide bars 34, 34 by screwing the screws 41 into the screw holes 38 through the screw insertion holes 40, and the holding plate 35. Will slide along both guide bars 34, 34. Further, a compression coil spring 43 is interposed between one side of the holding plate 35 and a support rod 42 protruding from the back surface of the main body frame 2 on the same side, and the holding plate 35 is always urged toward the compression coil spring 43 side. It has become so. On the rear surface of the holding plate 35, a horizontal shutter plate 44 that opens and closes the discharge port 31 at the lower end of the vertical flange 30 is integrally provided. A stop piece 45 protruding upward is provided on one side in the sliding direction of the shutter plate 44, and a stop cylinder 46 is integrally provided on the lower surface of the shutter plate 44.

  When the holding plate 35 is slid to one side by the bias of the compression coil spring 43, the stop piece 45 comes into contact with the outer surface of the vertical flange 30 and stops, and the discharge port 31 is blocked by the shutter plate 44, The game balls staying in the vertical rod portion 30 and the ball discharge rod 29 are prevented from spilling. Further, when the holding plate 35 slides to the other side against the bias of the compression coil spring 43, the stop piece 45 moves away from the outer surface of the vertical hook portion 30, and the shutter plate 44 moves, and the discharge port 31 is moved. open. As a result, the game ball that initially stayed in the vertical bowl 30 in the ball discharge bowl 29 is discharged to the ball storage section 8 a of the ball tray 8 by pulling the tray 16.

  Further, in the vertical flange 30 which is the downstream end of the ball discharge rod 29, the tray plate 16 and the vertical flange 30 communicate with the discharge port 31 at a position facing the tip when the shutter plate 44 advances. A notch recess 47 through which a game ball located between the two can pass is opened. The distance from the upper surface of the tray 16 to the upper end of the notch recess 47 is formed to be equal to or greater than the diameter dimension (11 mm) of the game ball, and the distance from the upper surface of the shutter plate 44 to the upper end of the notch recess 47 is less than the diameter dimension of the game ball. Is set. This is because when the front plate 7 is opened, the game ball located between the upper surface of the saucer portion 16 and the discharge port 31 at the lower end of the vertical saddle portion 30 is escaped to the outside so that the ball does not bite, What is necessary is just to set suitably within the said dimension.

  Further, a retraction space 48 for receiving a game ball spilled from the notch recess 47 is formed in the tray 16 outside the notch recess 47 of the vertical saddle portion 30 in the ball discharge rod 29. This is to prevent the game ball that has spilled from the notch recess 47 from accidentally getting over the saucer 16 and falling outside the pachinko gaming machine P. This game ball is also a prize ball as described above, and is obtained by the player, so dropping and losing it will give a disadvantage to the player.

  The pachinko gaming machine P according to the present invention has the above configuration, and its operation will be described with reference to FIGS. In the state where the front plate 7 is closed on the front surface of the main body frame 2, the tray 16 of the ball tray 8 protrudes to the back side of the main frame 2 as shown in FIGS. A discharge port 31 at the lower end of the vertical flange 30 faces upward. In this case, the stop cylinder 46 on the lower surface of the shutter plate 44 in the shutter mechanism 33 is moved by being pushed by the outer surface of the tray part 16, and the discharge port 31 at the lower end of the vertical hook part 30 is opened. At this time, the game balls paid out from the ball payout device 28 are guided to the ball discharge rod 29 and discharged to the tray 16 through the vertical rod portion 30.

  Therefore, for example, when a trouble occurs in the launch rail 19 and the front plate 7 is opened for inspection, initially, the tray 16 and the front plate 7 are moved together with the front plate 7 as shown in FIGS. 7 (B) and 8 (B). As it rotates in a predetermined direction, the stop cylinder 46 that has been in contact with the outer surface of the tray 16 also moves in the same direction as shown in FIG. The outlet 31 is blocked. In this case, if there is a game ball B1 just between the vertical saddle portion 30 and the saucer portion 16, the game ball B1 originally has the front end edge 44a of the shutter plate 44 and the vertical saddle portion 30 facing the front end edge 44a. There is a risk that the ball receiving portion 16 or the vertical flange portion 30 may be damaged due to being caught between the side walls 30a of the steel plate and causing a ball bite. However, even if the game ball B1 is pushed to one side by the front end edge 44a of the shutter plate 44, the notch recess 47 is formed in the vertical saddle portion 30 in that direction. The outlet 31 is closed and pushed out to the outside of the vertical hook 30 through the notch recess 47 as shown by the arrow in FIG. The pushed game ball B1 is received in the retreat space 48.

  Then, the front plate 7 is further opened, and the stop piece 45 is brought into contact with the outer surface of the vertical hook portion 30 before the saucer portion 16 is separated from the vertical hook portion 30 as shown in FIGS. 7 (c) and 8 (c). In contact therewith, the discharge port 31 at the lower end of the vertical flange 30 is completely closed by the shutter plate 44. Accordingly, the game ball spills from the vertical saddle portion 30 during the operation of the tray portion 16 and the shutter mechanism 33 shown in FIGS. 7 (B), 8 (B), 7 (C), and 8 (C). Never fall.

  In this way, the present invention extends the receiving tray 16 that protrudes to the rear side of the main body frame 2 when the upper surface is released to the ball receiving tray 8 and closes the front plate 7, and is formed at the downstream end of the ball discharge basket 29. When the front plate 7 is closed, a lower end discharge port 31 forms a single vertical hook 30 facing the upper part of the tray 16. Further, when the front plate 7 is closed by sliding horizontally between the discharge port 31 at the lower end of the vertical hook 30 and the upper surface of the tray 16 and being always urged to one side by the elastic member 43, the tray 16 is closed. The shutter plate 44 is moved backward to open the discharge port 31 and push the compression plate spring 43 to close the discharge port 31 when the front plate 7 is opened. Further, the width in the direction in which the shutter plate 44 slides at the discharge port 31 of the ball discharge rod 29 is set to the diameter size of the game ball, and at the lower end edge of the vertical saddle portion 30, the tip of the shutter plate 44 advances. A notch recess 47 for pushing the game ball B1 located between the saucer part 16 and the vertical saddle part 30 to the outside by the shutter plate 44 that moves forward is opened at a position opposite to the saucer part 16, and the notch recess 47 in the saucer part 16 is A retreat space 48 having a predetermined width in which the game ball B1 pushed out from the notch recess 47 is retained is provided outside.

  Therefore, when the front plate 7 is opened, the shutter plate 44 closes the discharge port 31 as the tray 16 moves away from the discharge port 31 at the lower end of the vertical flange 30. In addition, even if the front plate 7 is opened while the game ball remains in the ball discharge bowl 29, the game ball B1 pushed by the shutter plate 44 is pushed out to the outside through the notch recess 47 and is located outside the same. It will be received by the evacuation space 48. Accordingly, since the sliding stroke of the shutter plate 44 can be set to the minimum necessary size, not only the ball spills from the discharge port 31 but also the ball biting does not occur at all, and the ball discharge basket 29 and the ball tray 8 are damaged. The front plate 7 can be opened and closed without worry. Further, the game ball B1 pushed out from the notch recess 47 remains in the tray 16 as it is and does not fall below the pachinko gaming machine P. By the way, the minimum required sliding stroke of the shutter plate 44 is sufficient if the game ball does not fall from the discharge port 31. Therefore, when the discharge port 31 is closed, the shutter plate 44 moves to the discharge port 31 with the radius of the game ball. It may be in a state where it is closed with a slightly longer dimension, specifically 7 to 8 mm.

  In the present invention, the vertical flange 30 is formed in a rectangular tube shape, but may be a cylindrical shape or may be a polygonal shape. In addition, a single vertical hook 30 is provided at the downstream end of the ball discharge rod 29 and the discharge port 31 is opened at the lower end. For example, the shutter plate 44 at the discharge port 31 of the ball discharge rod 29 is slid. If the condition that the width in the moving direction is the diameter dimension of the game ball is satisfied, the vertical rod portion 30 has two strips and the discharge port 31 can discharge two pachinko balls simultaneously as shown in FIG. It is also good.

  Further, it is not always necessary to form the vertical hook portion 30 at the downstream end portion of the ball discharge rod 29, and the downstream end portion may face substantially in the horizontal direction as long as the discharge port 31 is provided on the bottom surface. Furthermore, although the shutter plate 44 is slid in parallel along the back surface of the front plate 7, it slides in a direction orthogonal to the front plate 7, that is, from the rear side of the saucer portion 16. The shutter plate may be slid along the upper surface to the front plate 7 side, and the shutter plate may be rotated in a horizontal plane around the appropriate position.
