Thus, a balance in the game balls extremely effectively can be lost in the ridge line part even if the plurality of game balls are caught between the opening/closing member and the periphery when the opening/closing member is opened, and hence preventing occurrence of inconvenience, such as ball-jamming, as much as possible.

Description

  The present invention relates to a ball game machine such as a pachinko machine, and more particularly to a ball game machine having a game area with a winning device having a structure for winning a game ball with an opening / closing member.

  Conventionally, in a pachinko machine referred to as a so-called first type pachinko machine as a ball game machine, a game ball staying in a ball tray has been launched into the game area of the game board in accordance with the operation of the launch handle. After that, it is configured to flow down the board surface while being guided by obstacle nails, windmills and the like in the game area, and enter various winning holes, or flow into the out holes below the game board without entering.

  In such a pachinko machine, when a player enters a general winning opening, a corresponding number of game balls are paid out, and when a player enters a starting chucker, a jackpot lottery is performed based on this and a predetermined number The game balls are paid out, and a predetermined effect display is performed on the screen of an image display device such as a liquid crystal provided in the central portion of the game board according to the result of the lottery. When a big hit occurs, a large winning device (lower attacker) called a lower attacker in the game area is opened, and a large amount of game balls are paid out corresponding to the incoming game.

  By the way, in a bullet ball game machine having the above-mentioned large winning device (lower attacker), a game ball may be sandwiched between the open / close door of the large winning device and the inner surface of the glass plate covering the front surface. An abnormality may occur in the mechanism that connects the solenoid on the winning device side and the opening / closing door, which may cause inconveniences such as the opening / closing door not opening despite the excitation of the solenoid. In a pachinko machine, the predetermined opening time of the grand prize winning device is set by the excitation time of the solenoid, so that the prize ball to be obtained cannot be received when the predetermined time passes without the big winning device actually being opened. This causes a problem such as a player suffering a disadvantage.

  Thus, a ball game machine configured to eliminate such problems has been proposed (see Patent Document 1). In the ball game machine, even when the solenoid is controlled so as to open the open / close door of the variable winning device having the large winning device (lower attacker), the detection signal from the opening detection sensor is not obtained (that is, the opening / closing is not performed). When the door is not open), the door is temporarily closed (turned in the closing direction). As a result, when a game ball is sandwiched between the open / close door of the grand prize winning device and the inner surface of the glass plate, the game ball can be dropped to eliminate the ball clogging.

JP 2001-327686 A

  However, the configuration of the ball game machine described in Patent Document 1 is effective for the big winning device (lower attacker) located at the lower part of the game area, but the ball game machine having the following configuration is used. The effect could not be expected for the upper attacker. That is, in recent years, the first big winning device (lower attacker) is arranged in the lower part of the game area, and the second big winning device (upper attacker) is provided on the upper part of the center object arranged in the central part of the game area. A gaming machine has appeared. In such a ball game machine, the first big hit to obtain a large number of prize balls by opening and closing the first big winning device with the winning at the starting winning opening (starting chucker) and the second big When a winning lottery with respect to the second jackpot for obtaining a large amount of prize balls by opening and closing the winning device is performed and the first jackpot is won, the first grand prize winning device is filled with a predetermined number of rounds. Open and close to allow a large number of game balls to be won, and when winning the second jackpot, open and close the second large winning device for a predetermined number of rounds to win a large number of game balls. Allow.

  Such a recent second prize-winning device (upper attacker) in a ball game machine has an opening / closing member (so-called blade) that opens and closes with an axis perpendicular to the game board surface as a fulcrum. Due to the structure in which the opening and closing member is opened and closed by switching, a plurality of game balls may be caught and fitted between the opening and closing member, the front wall inner surface of the front and the rear rear wall of the rear, and the ball may be clogged. There is.

  Thus, the ball clogging release configuration described in Patent Document 1 cannot be applied to a ball game machine having a structure that may cause a ball clogging in the second big winning device (upper attacker). In other words, even if the opening / closing member is operated so as to be closed once when the ball clogging occurs, it becomes difficult for the opening / closing member itself to move in the closing direction.

  Therefore, the present invention includes a winning device having an opening and closing member that opens and closes around a support shaft in a direction perpendicular to the game board, but may occur when the opening and closing member opens and closes to receive a game ball. An object of the present invention is to provide a ball game machine capable of preventing ball clogging as much as possible with a simple configuration.

The present invention according to claim 1 (see, for example, FIG. 1 to FIG. 15) includes a game board (10) covered with a light transmission plate (12), and the light transmission plate (12) and game board (10). A game area (PA) surrounded by and a winning device (14) capable of winning a game ball (Ba) launched into the gaming area (PA), wherein the winning device (14) It is rotatable about a support shaft (39) perpendicular to the board surface of the game board (10) between an open position (a position indicated by a two-dot chain line in FIG. 4) and a closed position (a position indicated by a one-dot chain line in FIG. 4). In a ball game machine (PM) having an opening and closing member (35),
The opening / closing member (35) has a flat first rolling surface (35a) and an angle with the first rolling surface (35a) as a rolling part for rolling the game ball (Ba) at the open position. And a flat second rolling surface (35b) of different shape and a ridge line portion (35c) formed in a mountain shape by the first and second rolling surfaces (35a, 35b),

It exists in the bullet ball game machine (PM) of Claim 1 or 2.

  Note that the reference numerals in the parentheses are for comparison with the drawings, but this is for convenience to facilitate understanding of the invention and has no influence on the description of the claims. It is not a thing.

  According to the first aspect of the present invention, the opening and closing member serves as a rolling part for rolling the game ball in the open position, and the first and second rolling surfaces that are flat, and the first and second rolling surfaces. The ridge line portion corresponds to a position where a plurality of game balls can be easily fitted and stabilized when the rolling portion of the opening and closing member is formed in one plane. When the opening / closing member is opened, the plurality of game balls are caught between the opening / closing member, the inner surface of the front wall portion, and the rear wall portion facing the front wall portion at the position where the opening / closing member is easily stabilized. Even if it is going to be in a state, the balance of these plurality of game balls can be destroyed very effectively at the ridgeline portion. Thereby, it is possible to prevent as much as possible the occurrence of inconvenience such as ball clogging. Moreover, such a ball clogging prevention structure can be realized by an extremely simple process of forming the ridge line portion and the second rolling surface on the opening / closing member having the first rolling surface, thereby reducing the product cost. be able to.

  According to the second aspect of the present invention, since the angle formed by the edge of the winning opening in the front wall portion and the first rolling surface of the opening / closing member in the open position is an obtuse angle, the opening / closing member and the inner surface of the light transmission plate Even if ball clogging is likely to occur between the two, the game balls move along the edge of the front wall with the force when the opening / closing member returns to the closed position, compared to the case where the angle is acute. Somewhat moved and lost balance. Thereby, the effect by the ball clogging prevention structure which provided the ridgeline part and the 2nd rolling surface in the opening / closing member can be heightened more.

  According to the third aspect of the present invention, the open / close member is stopped at a predetermined angular position before full opening to form an open state, and when closing, the open / close member is further opened from the predetermined angular position and then moved toward the closed position. In addition, since the stepping motor is controlled, the opening / closing member can be smoothly returned to the closed position while reliably breaking the ball clogging even if the ball clogging is likely to occur. For this reason, when the opening / closing operation of the opening / closing member between the opening position and the closing position is performed a plurality of times, the effect of eliminating the ball clogging by the ridge line portion of the opening / closing member and the change of the opening angle of the opening / closing member by the stepping motor The effect of eliminating ball clogging can also be obtained, and therefore a double ball clogging eliminating effect can be expected.

  When a game ball launched into the game area PA wins a start winning device (not shown) at the position of the opening 17, a special symbol lottery (the first jackpot is won) by a lottery function of the main control board included in the control unit 30. As a result, a special symbol and a decorative symbol are variably displayed for a predetermined time on an image display device (not shown) at the position of the opening 15. In this special symbol lottery, based on the random number value acquired when winning the start winning device, the first big win and the second big winning device 14 for opening and closing the lid 19a of the first big winning device 19 by a predetermined number of rounds. A second jackpot that opens and closes the opening / closing member 35 by a predetermined number of rounds, and a disengagement that does not become one of the first and second jackpots are determined. On the display unit of the image display device, a decoration pattern corresponding to the special symbol corresponding to the determination result of the special symbol lottery is displayed, and a display mode (for example, “777”, “555” that finally matches the three symbols is displayed. ”“ 333 ”), and finally, a display mode in which the three symbols do not match (for example,“ 527 ”“ 346 ”), etc. are displayed.

  When the game ball is introduced to the stage S from the discharge port 24 through the warp introduction port 16 of the center ornament 13, the game ball rolls to the left and right so as to temporarily stop on the stage S, and finally Specifically, it falls below the stage S and wins a start winning opening, or flows down to the game area PA without being awarded to the starting winning opening and is taken into the lower out opening 23.

  When the first jackpot is won, the lid 19a of the first big winning device 19 as the lower attacker is opened a predetermined number of times. That is, when the lid body 19a is opened for a predetermined time, or when, for example, nine or more game balls are won, the lid body 19a is once closed and closed by a predetermined number of times (for example, 15 times) repeated continuously. During this time, the game ball Ba launched into the game area PA by the operation of the operation handle 8 by the player is received by the opened lid body 19a, thereby corresponding to each game ball won in the first grand prize winning device 19 respectively. Then, a large amount of game balls (prize balls) to be paid out are released onto the ball tray 6.

  On the other hand, when the second jackpot is won, the opening / closing member 35 of the second big winning device 14 as the upper attacker is different in stages (for example, three stages (16 times, 32 times, 48 times)). Opened. In other words, the game ball Ba launched into the game area PA is received and won at the upper part of the game area PA by the opening / closing member 35 that is opened in small increments every predetermined time. In this way, a large amount of game balls (prize balls) to be paid out in correspondence with each game ball won in the second grand prize winning device 14 is discharged onto the ball tray 6. The game ball Ba which has won the second grand prize winning device 14 when the opening / closing member 35 is opened is introduced from the game ball introduction path 26 into the opening 40 and detected by the detection sensor, and then passes through the discharge path 36 to play the game board. 10 is discharged to the back side.

  Here, the operation of the opening / closing member 35 of the second grand prize winning device 14, which is a feature of the present invention, will be described with reference to FIGS.

That is, in the second grand prize winning device 14, the opening / closing member 35 performs an opening operation from the closing position indicated by the one-dot chain line in FIG. 4 to the opening position indicated by the two-dot chain line in FIG. At the time, in the basic technique shown in FIG. 8C that does not have the ridge 35c and the second rolling surface 35b according to the present invention, the inner surface of the front wall 37 and the first rolling surface located on the near side of the figure. When the gaming ball Ba _1, Ba ₂ between 35a is pushed by the frictional force, the frictional forces of the game balls Ba _1, Ba ₂ is a frictional force and surrounding each other, is a fear that stable without unbalancing is there. If a ball jam occurs due to this, it is difficult to eliminate the ball jam unless the player calls an attendant at the game hall and releases the ball jam directly by the attendant.

On the other hand, in this embodiment provided with the ridge line portion 35c, as shown in FIG. 8A, the inner surface 31a of the upper wall portion 31, the inner surface of the front wall portion 37, the inner surface of the rear wall portion 33 on the front side in FIG. Even when the game balls Ba ₁ and Ba ₂ are pushed in between the first rolling surface 35a, these gaming balls Ba ₁ and Ba ₂ are peaks following the second rolling surface 35b having a large gradient. The balance is lost on the ridge line portion 35c and cannot be stabilized. That is, as shown in FIG. 9A, the lower game ball Ba ₁ rolls and moves in the direction of arrow a on the ridge 35c, and the upper game ball Ba ₂ flows down in the direction of arrow b. As shown in b), the game ball Ba ₁ flows down from the second rolling surface 35b in the direction of the arrow c, and the game ball Ba ₂ falls in the direction of the arrow d while the game ball Ba ₁ falls along the second rolling surface 35b. It will flow down as well. As described above, according to the present embodiment, the game balls Ba ₁ and Ba ₂ collapse before the ball clogging occurs, and therefore the occurrence of the ball clogging as described in FIG. 8C is reliably avoided. The

  In other words, in the present embodiment, the opening / closing member 35 serves as the first and second rolling surfaces 35a and 35b that are flat, and the first and second rolling surfaces as a rolling part that rolls the game ball Ba in the open position. A ridge line portion 35c formed in a mountain shape by the moving surfaces 35a and 35b, and when the rolling portion of the opening / closing member 35 is formed in a single plane, the ridge line portion 35c is fitted with a plurality of game balls. It is provided corresponding to the position A that is easy to stabilize. For this reason, when the opening / closing member 35 is opened, the plurality of game balls at the position A that is easy to stabilize are the opening / closing member 35, the inner surface 31a of the upper wall portion 31, the inner surface of the decorative panel 38, the inner surface of the front wall portion 37, and the rear wall portion. 33, even when trying to get caught between the inner surfaces and get wedged between each other, the balance of these game balls can be very effectively broken at the ridge line portion 35c and flowed to the second rolling surface 35b. The occurrence of clogging can be prevented as much as possible. In addition, such a ball clogging prevention structure can be realized by an extremely simple process of forming the ridge line portion 35c and the second rolling surface 35b on the opening / closing member 35 having the first rolling surface 35a. Can be reduced.

Further, as in the basic technique shown in FIGS. 11A and 11B, the angle θ formed by the edge 38a formed on the decorative panel 38 and the first rolling surface 35a at the open position is an acute angle. In this case, when the game ball Ba ₂ is engaged with the game ball Ba ₁ fitted between the inner surface of the transparent glass plate 12 and the first rolling surface 35 a, the opening / closing is attempted to return to the closed position by the force of the solenoid. The game balls Ba ₁ and Ba ₂ are further bitten between the first rolling surface 35a of the member 35 and the acute-angled edge portion 38a, so that it becomes more difficult to eliminate the ball clogging.

On the other hand, in the present embodiment shown in FIGS. 10A and 10B, the edge 37a formed on the front wall portion 37 extended from the decorative panel 38, and the first rolling surface 35a in the open position, Is an obtuse angle, so that even when the game ball Ba ₂ is about to bite into the game ball Ba ₁ clogged between the inner surface of the transparent glass plate 12 and the first rolling surface 35a, it is blocked by the solenoid force. first rolling surface 35a of the closing member 35 to be restored to the position, it acts to break the balance of the game ball _Ba 1, Ba ₂ to discharge game ball Ba ₁ along the edge 37a. For this reason, the possibility of ball clogging is extremely low.

  That is, in the present embodiment, the angle θ formed by the edge 37a of the winning opening 48 in the front wall portion 37 and the first rolling surface 35a of the opening / closing member 35 in the open position is an obtuse angle. Even if a ball clogging occurs between the inner surface of the transparent glass plate 12, these game balls have a greater force when the opening and closing member 35 returns to the closed position than the case where the angle θ is an acute angle. It is moved a little along the edge 37a and moved into the game ball introduction path 26 while being easily out of balance. Thereby, the effect by the ball clogging prevention structure which provided the ridgeline part 35c and the 2nd rolling surface 35b in the opening / closing member 35 can be heightened more.

  Note that the opening / closing member 35 shown in FIG. 8B is obtained by making the position of the ridge line portion 35c slightly different from the opening / closing member 35 shown in FIG. 8A. In the opening / closing member 35 in FIG. 8B, a ridge line portion 35c is formed on the inner side (left side in the drawing) of the game ball introduction path 26 than the ridge line portion 35c of the opening / closing member 35 in FIG. 8A. In the opening / closing member 35, since the entire first rolling surface 35a is inclined toward the front side in FIG. 8B, the ridge line portion 35c is formed to be inclined obliquely with respect to the longitudinal direction of the opening / closing member 35. ing. Also with such an opening / closing member 35, the same effect as the above-described opening / closing member 35 can be obtained. In addition, although the ridge line part 35c demonstrated using FIG. 5-7 in 1st Embodiment was formed in the direction orthogonal to the longitudinal direction of the opening / closing member 35, also in this opening / closing member 35, the ridge line part 35c is formed. It can be formed obliquely as in FIG.

<Second Embodiment>
Next, a second embodiment according to the present invention will be described with reference to FIGS. In the present embodiment, the configuration relating to the driving of the opening / closing member 35 is different from that of the first embodiment, but the other configurations are the same as those of the first embodiment, and therefore, the same reference numerals are given and explanations thereof are made. Is omitted. Note that FIG. 13A in this embodiment shows a state in which the opening / closing member 35 in FIG. 4 is stopped at a predetermined angular position in front of the fully open position (two-dot chain line position), and FIG. Indicates a state of further opening from the predetermined angular position toward the fully open position.

  In the present embodiment, a stepping motor 41 for opening and closing the opening / closing member 35 is provided, and the stepping motor 41 driven and controlled by the control unit 30 is provided in the second grand prize winning device 14. In the present embodiment, the solenoid 34 (see FIG. 6) that opens and closes the opening and closing member 35 in the first embodiment is not provided.

  In this embodiment, the control unit 30 stops the opening / closing member 35 at a predetermined angle position (FIG. 13A) before full opening to form an open state, and further opens the predetermined angle position when closing. Thereafter, the stepping motor 41 is controlled so as to be directed to the closing position.

  In the stepping motor 41, the pinion 41 a fixed to the rotating shaft is engaged with the tooth portion 42 a of the spur gear 42 in a state where the motor body is fixed to the back surface of the rear wall portion 33. The center of the spur gear 42 is fixed to a support shaft 39 of an opening / closing member 35 protruding from the rear surface of the rear wall 33. At the position facing the tooth portion 42a of the spur gear 42 on the back side of the rear wall portion 33, the movement of the tooth portion 42a is detected and the rotation direction and rotation angle of the spur gear 42 (that is, the rotation direction and rotation of the opening / closing member 35). A detection sensor 46 for detecting (angle) is arranged. Reference numeral 42b is a mark attached to the back surface of the spur gear 42, and the rotational position of the spur gear 42 can be determined by looking at the difference in position of the mark 42b.

  In the present embodiment, the control unit 30 causes the stepping motor 41 to move in the positive direction (direction opening from the closed position in FIG. 12A) and the negative direction (blocked in FIG. 12A) by a certain number of pulse signals. Rotation direction). By this control, the control unit 30 stops the opening / closing member 35 at a predetermined angular position (FIG. 13A) before full opening to form an open state, and when closing, further increases the forward direction from the predetermined angular position. After opening, it can be directed to the closed position.

  As described above, according to the present embodiment, even when, for example, a plurality of game balls Ba are clogged in the open state at the predetermined angular position, the open position is changed to the closed position in FIG. When returning, as shown in FIG. 14 (a), the opening / closing member 35 further rotates in the opening direction (positive direction) and then rotates in the negative direction so as to close the second big prize winning device 14. Even if a ball clogging is likely to occur in the second grand prize winning device 14, the clogging of the ball can be reliably broken and introduced into the game ball introduction path 26, and the opening / closing member 35 can be smoothly returned to the closed position. it can. For this reason, in this embodiment, when the opening / closing operation of the opening / closing member 35 performed between the open position and the closed position is performed a plurality of times, the ball clogging is eliminated by the ridge line portion 35c of the opening / closing member 35 in the first embodiment. In addition to the effect, the effect of eliminating ball clogging due to the change in the opening angle of the opening / closing member 35 by the stepping motor 41 can also be obtained, and therefore a double ball clogging eliminating effect can be expected.

  Next, a modification according to the first embodiment will be described with reference to FIGS. 15 (a), (b), and (c). In this modification, the configuration using the solenoid 34 (see FIG. 6) for driving the opening / closing member 35 is the same as that of the first embodiment, but in FIG. 15, the solenoid 34 is not shown for convenience. . Moreover, in this modification, although it differs from 1st Embodiment by the point which has arrange | positioned the vibration motor 43 and the proximity | contact proximity flat sensor 45 in the back surface side of the rear wall part 33, since the structure of other than that is the same, it is the same code | symbol. A description thereof will be omitted.

  As shown in FIGS. 15A to 15C, the proximity flat sensor 45 is disposed on the back surface side of the rear wall portion 33 at a position facing the opening / closing portion of the opening / closing member 35 in the second big prize winning device 14. Yes. A vibration motor 43 in a state where the main body is fixed to the rear wall 33 is arranged on the rear surface side of the rear wall 33 so that vibration can be transmitted to the rear wall 33.

  In the vibration motor 43, an eccentric weight member 44 is fixed in an eccentric state at the tip of the rotating shaft 43a, and is configured to generate vibration by rotating the eccentric weight member 44 during driving. Further, the proximity flat sensor 45 detects a clogged ball that has occurred in the second prize-winning device 14 as shown in FIG. 15A, and the control unit 30 controls the proximity flat sensor 45 in the special gaming state. Based on the detection result (signal) of the ball clogging, the vibration motor 43 is driven for a predetermined time (or until the ball clogging is detected by the proximity flat sensor 45) to break the ball clogging and release it.

  According to this modified example, in the second big prize device 14 including the opening / closing member 35 having the ridge line portion 35c and the second rolling surface 35b, a ball formed by the ridge line portion 35c of the opening / closing member 35 in the first embodiment. In addition to the effect of eliminating clogging, the effect of eliminating ball clogging due to vibration based on the eccentric weight member 44 rotated by driving of the vibration motor 43 can be obtained, and therefore a double ball clogging eliminating effect can be expected.
