Description

  The present invention relates to a variable winning device and a gaming machine using the same, and in particular, includes a crime prevention mechanism for preventing an illegal act of unjustly acquiring a winning ball by opening a movable wing piece that is rotatably provided by an external operation. The present invention relates to a variable winning device and a gaming machine using the same.

  Conventionally, as a variable winning device provided in various game machines including a ball game machine such as a pachinko machine and an alepachi machine, an electric motor such as a solenoid is supported by freely supporting a movable wing piece on both sides of a ball receiving opening. There are some cases where the movable wing piece is opened and closed by driving of the driving source to make the game ball enter an open state where the game ball can enter, or the game ball cannot enter or close when it is difficult to enter. When the solenoid is not activated, this variable prize winning device allows an unauthorized tool such as a piano wire or a cell board to enter from the outside between the front of the game board and the glass board and hook it on the movable wing piece, It is a structure that can open the piece forcibly. For this reason, there have been numerous fraudulent acts that unfairly win prize balls, so even if you try to open the movable wing piece of the variable prize device from the outside, a variable winning device that can prevent fraud without opening the movable wing piece is proposed. (For example, refer to Patent Document 1).

  However, in the variable prize winning device disclosed in the patent document, the side end of the connecting rod and a locking piece provided on the crank member are brought into contact with each other to prevent rotation by an external force, but the connecting rod and the crank member are rotated simultaneously by excitation of a solenoid. Since it is a structure that moves and there is only one point that prevents rotation, the lock is easily released and it is easy to bend and wear. Furthermore, since the rotation directions of the connecting rod and the crank member are the same, there has been a problem that if it is forcibly opened, the lock is easily released and a reliable locking effect cannot be expected.

  The present invention has been made to solve the above-mentioned problems, and even if an attempt is made to open the movable blade piece from the outside illegally with a simple configuration, the movable blade piece is not opened, and illegal acts are reliably prevented. It is an object of the present invention to provide a variable winning device that can perform a game and a gaming machine using the same.

In order to achieve the above object, the invention according to claim 1 is characterized in that the movable wing piece pivotally supported by the rotating shaft is opened and closed via the transmission means for transmitting the driving force of the electric drive source, A variable winning device that changes between an open state in which a ball can be entered and a closed state in which a game ball cannot enter or is difficult to enter, wherein the movable wing piece is synchronized with a rotating shaft of the movable wing piece and A cam member having an operating portion linked to the transmission means is provided at a position eccentric to the rotation shaft, and the transmission means includes a connecting member connected to the electric drive source, and an operating member linked to the cam member.

The “transmission means” here refers to a mechanism element that transmits the driving force of the electric drive source to the movable wing piece to open and close the movable wing piece, and the number of mechanism elements is not limited. And transmitting the driving force of the electric drive source to the movable blade piece via a plurality of mechanism elements. “Electric drive source” is a general term for actuators that operate a movable body in response to an electrical signal. For example, a motor and a solenoid correspond to the electrical drive source.

  With the above configuration, when the movable blade piece is in the closed state when the electric drive source is not driven, the rotation operation of the operation unit is locked by the locking means to prevent the movable blade piece from rotating in the opening direction. . Then, when the electric drive source is driven, the locking means is released to release the rotation prevention of the operation portion, and the driving force of the electric drive source is transmitted to the movable blade piece to be rotated. In other words, the movable blade piece can be rotated only by the driving force of the electric drive source. With this configuration, even when an unnecessary acting force in the opening direction is applied to the movable blade piece in the non-driven state of the electric drive source, the movable blade piece is not opened by the locking means.

In addition, with this configuration, when the electric drive source is not driven, the stopper of the connecting member is opposed to the lock portion when the operating member is in the downward movement position, and the rotation of the operating member is locked to prevent the movable blade piece from rotating. Is done. In addition, when the electric drive source is driven, the connecting member moves independently for a predetermined stroke, so that the stopper is separated from the lock portion and unlocked, and further, the operating member rotates by moving the connecting member. The movable blade piece opens.

Is formed by bulging a stopper, which is located on the rotation path of the linkage pin when the electrical drive source is not driven, and stops when the electrical drive source is driven. The stopper is separated from the rotation track of the linkage pin by a single movement of the connecting member for a predetermined stroke.

The invention according to claim 4 is characterized in that the variable winning device according to any one of claims 1 to 3 is provided in a gaming machine, so that it is possible to realize an amusement machine rich in entertainment and having high game characteristics. become.

  Further, a transmission means is constituted by a connecting member that linearly moves by driving of an electric drive source and an operating member that swings in association with the connecting member, and a connecting pin protruding from the operating member is provided in a connecting hole formed in the connecting member. By loose insertion, the linear movement of the connecting member is transmitted to the operating member so as to swing, and the movable blade piece acts in the opening direction in the connecting hole when the electric drive source is not driven. When the electric drive source is driven, only the connecting member is moved by a predetermined distance to release the lock means and then engage the linkage pin. It is preferable to set the inner diameter of the linkage hole so as to swing the operating member.

  The locking means may be configured to be locked by surface contact. For example, a planar blocking portion is formed on the stopper and a planar portion capable of being in surface contact with the blocking portion is formed on the linkage pin, and an electric drive source. Since the planar portion of the linking pin is pressed in a direction different from the movable direction of the connecting member in a state where the surface portion of the linking pin is in surface contact with the stopper when not driven, the locking effect is ensured.

  Further, it is preferable to provide a restricting means for preventing the connecting member from moving in the pressing direction when the lock portion presses the stopper. Even if an unnecessary external force acts on the stopper, the connecting member does not move and the operating member does not malfunction.

It is set to open once.

  As shown in FIG. 2, the variable winning device 12 has an opening at the center of the base plate 16, and a box frame 18 having a depth space that communicates with the opening and allows game balls to play behind the base plate 16. Is provided. A pair of substantially symmetric movable wing pieces 19 that are positioned on the left and right sides of the opening and open and close the prize opening are axially attached to face each other, and a plurality of inside the box frame 18 positioned between the two movable wing pieces 19 is provided. Divided into passages, a special winning opening 50 and a general winning opening 51 are formed. The special state advantageous to the player is continued on condition that the game ball wins the special winning opening 50.

  3 and 4, the movable wing piece 19 includes a circular rod-shaped rotation shaft 25 that is substantially orthogonal to the surface of the game board 4 and projects to the back side of the base plate 16. A cam member 26 is provided in a notch shape. The cam member 26 includes a metal operation pin 31 as an operation portion at a position eccentric from the rotation shaft 25, and the operation pin 31 is rotated integrally with the movable blade piece 19. Therefore, the track of the operation pin 31 has an arc shape that rotates around the rotation shaft 25.

  In addition, a pair of direct acting solenoids 22 provided with springs 44 and plungers 45 as electrical drive sources on the rear surface of the box frame 18 are provided corresponding to the movable blade pieces 19, and the solenoids 22 have a driving force. It is provided vertically so as to be generated in the vertical direction with respect to the game board 4. The plunger 45 is provided with a transmission means for transmitting the driving force of the solenoid 22 to the movable wing piece 19, and the plunger 45 moves up and down by the excitation of the solenoid 22, and the driving force is cammed via the transmission means. The movable blade 19 is transmitted to the member 26 to rotate. The return spring 44 is not necessarily provided, and may be moved back by the weight of the plunger 45 or the weight of the connecting member 27 of the transmission means described later.

  Next, the transmission means will be described. Since a pair of transmission means are provided symmetrically corresponding to the movable blade piece 19 and the solenoid 22, one (left side in front view) is illustrated and described in FIGS. To do. The transmission means includes a connecting member 27 that is connected to the plunger 45 of the solenoid 22 and moves straight up and down in synchronization with the driving of the solenoid 22, and an operating member 23 that is linked to the cam member 26. Specifically, the actuating member 23 is provided at one end so as to be tiltable on a support shaft 28 provided on the rear wall of the box frame 18 so as to be substantially orthogonal to the surface of the game board 4, and in a normal state, the actuating member 23 is moved down by its own weight. I'm in. The other end is provided with an elongated engagement hole 29 as an engagement portion that engages the operation pin 31 of the cam member 26 to cause the cam member 26 to rotate. In addition, a linkage pin 30 that is linked to the coupling member 27 protrudes in parallel with the operation pin 31 at a substantially intermediate position between the shaft support portion and the engagement hole 29. Then, as a locking means for preventing the movable blade piece 19 from rotating unnecessarily at a position eccentric from the support shaft 28 (in the embodiment, an upper position of the support shaft 28), a rib wall-shaped lock portion 32 is integrally projected. Forming.

  Further, the connecting member 27 is positioned on the rotation path of the lock portion 32 of the operating member 23 when the solenoid 22 is not driven, and the lock portion 32 of the operating member 23 stops and the operating member 23 rotates. A stopper 35 is provided integrally. The stopper 35 is formed in the shape of a bowl bent downward by about 70 °, and its lower surface serves as a blocking portion 35a against which the lock portion 32 stops. And as a connection part with the operation member 23, the connection hole 36 in which the connection pin 30 is loosely inserted is opened. As shown in FIG. 5A, the linking hole 36 has a hole area larger than the cross-sectional area of the operation pin 31 so as to be engaged with the linking pin 30 with a gap C that can be moved by a predetermined stroke alone. The connecting member 27 is provided in a substantially rectangular shape so as to expand in the movable direction (vertical direction in the embodiment). In addition, a restricting means for restricting the moving direction and range of the connecting member 27 is provided below the linkage hole 36. As a restricting means, a guide pin 37 protrudes from the box frame 18 in parallel with the support shaft 28, and a guide long hole 38 into which the guide pin 37 is loosely inserted is provided in the vertical direction. Then, the actuating member 23 and the connecting member 27 are connected via the connecting pin 30 and the connecting hole 36, and the connecting member 27 is linearly moved in the vertical direction in the same direction as the forward / backward movement of the plunger 45 driven by the solenoid 22. The member 23 converts the advancing / retreating motion of the connecting member 27 into a rotating motion in the vertical direction with the support shaft 28 as a fulcrum. Note that the stopper 35 may be formed separately and assembled to the connecting member 27 integrally.

  The variable winning device 12 having the above configuration supports the rotating shaft 25 to which the movable blade piece 19 is fixed substantially horizontally by a bearing or the like, and loosely inserts the operation pin 31 of the cam member 26 into the engagement hole 29 of the operating member 23. In cooperation, the driving force of the solenoid 22 is transmitted to the movable wing piece 19 so as to be opened and closed. At this time, as shown in FIG. 5 (a), the lock portion 32 is positioned relative to the side of the blocking portion 35a of the stopper 35, and the linkage pin 30 has a gap C below and a top in the linkage hole 36. In this state, there is a slight gap. In other words, even if an acting force is applied from the movable blade piece 19 side, the lock portion 32 is in a positional relationship where it first contacts and engages with the stopper 35 before the linking pin 30 contacts the upper end of the linking hole 36. The member 23 is prevented from rotating unnecessarily. In the embodiment, two solenoids 22 are provided so that each movable blade piece 19 can be opened and closed independently. However, the operation member 23 is operated by one solenoid 22 to open and close the movable blade piece 19. It may be.

  Next, the operation of the variable winning device 12 having the above configuration will be described. First, as shown in FIG. 5 (a), in a state where the solenoid 22 is not demagnetized and operated, the plunger 45 is in the downward movement position by the bias of the spring 44, and accordingly, the connecting member 27 is also the guide pin 37. The actuating member 23 tilts downward due to its own weight and is held at a position tilted downward by about 17 ° by a not-illustrated regulating portion. Further, the two movable wing pieces 19 are held in an upright state as shown by a solid line in FIG. At this time, the stopper 35 is positioned on the side of the lock portion 32 on the rotation path of the lock portion 32, and the rotation of the actuating member 23 is prevented by the stopper 35, whereby the movable blade piece 19 is unnecessarily opened. Rotating movement is blocked. Note that the restricting means for restricting the downwardly inclined position of the operating member 23 can also be achieved by restricting the rotation of the movable blade piece 19 or the cam member 26.

  On the other hand, when the solenoid 22 is excited, the plunger 45 moves upward against the bias of the spring 44 as shown in FIG. 5B, and the connecting member 27 slides upward while being regulated by the guide pin 37. Then, the stopper 35 is detached from the rotation path of the lock part 32 and moves to a predetermined position, and the rotation prevention of the lock part 32 is released. At this time, the movable blade piece 19 is still in the closed state. When the lock portion 32 is released from the rotation prevention of the stopper 35, the lower end portion of the linkage hole 36 comes into contact with and engages with the linkage pin 30 as shown in FIG. As shown in the figure, the linkage pin 30 is pushed up, and the cam member 26 is also rotated upward as the operating member 23 is rotated upward, and the rotating shaft 25 is rotated so that the movable blade piece 19 is centered on the rotating shaft 25. A predetermined angle is turned in the opening direction and the fully opened state shown by the chain line in FIG. 2 is obtained, so that the game ball can be easily won. Note that the lock portion 32 is positioned below the stopper 35 at a predetermined interval until the movable blade 19 is changed from the closed state to the open state as described above, and does not interfere with the stopper 35.

  Thereafter, when the solenoid 22 is demagnetized, the plunger 45 returns to the lowered position by the bias of the spring 44, the operating member 23 descends by its own weight as the connecting member 27 moves downward, and the cam member 26 is also engaged with the operation pin 31. While rotating in contact with the joint hole 29, the movable blade piece 19 is synchronously returned to the closed state shown in FIG. Even when the actuating member 23 does not return due to its own weight, the linkage pin 30 is pressed downward by the upper end of the linkage hole 36 as shown in FIG. The part 35a can push the lock part 32 to forcibly return the operating member 23 to the position shown in FIG.

  On the other hand, in the closed state of the movable wing piece 19 shown in FIG. 5 (a), the movable wing piece 19 or the cam member 26 and the operating member 23 are operated by an unauthorized tool such as a piano wire or a cell plate, and the movable wing piece 19 is moved. Even if it is forced to open, the lock portion 32 comes into contact with the blocking portion 35a of the stopper 35, and the acting force acts in a direction different from the moving direction of the connecting member 27, so that the rotating operation of the operating member 23 is blocked. For this reason, the movable wing piece 19 cannot be rotated, and the game ball cannot be illegally put into the winning opening. At this time, even if an excessive force is applied and the stopper 35 is pressed to forcibly shift the connecting member 27 in the lateral direction to rotate the actuating member 23, the guide pin 37 as the restricting means is guided by the guide slot 38. Therefore, the connecting member 27 does not move unnecessarily, and the locked state of the lock portion 32 can be reliably held.

  As described above, the variable winning device 12 according to the present embodiment has the transmission means for transmitting the driving force of the electric drive source to the movable blade piece 19 and the movable blade piece 19 in the non-driven state. Since the stopper 35 for preventing the rotation is provided and the prevention of the rotation of the stopper 35 is released when the electric drive source is driven, the movable blade 19 is opened by the stopper 35 when the electric drive source is not driven. Rotation in the direction is prevented. That is, the movable blade piece 19 is opened only when the electric drive source is driven.

  Further, the variable prize apparatus 12 according to the present embodiment can cope with the transmission means for transmitting the driving force of the electric drive source to the movable blade piece 19 with only a slight design change. Twelve normal operations can be ensured while cheating can be prevented. The stopper 35 can be retracted from the displacement path of the actuating member 23 by providing a gap C in which the connecting member 27 can move independently at the link between the actuating member 27 and the connecting member 27 constituting the transmission means. Since a time difference in the start of rotation of the movable blade 19 can be generated, the apparatus configuration can be simplified, contributing to weight reduction and compactness of the apparatus. Further, it is not necessary to create a new member for preventing fraud, and the cost of the mold or the like can be reduced.

  6 and 7 show another embodiment of the locking means, and the locking means is provided at the link portion between the connecting member 27 and the actuating member 23. FIG. In addition, the same code | symbol is attached | subjected and demonstrated to the same component as the said Example. Specifically, as shown in FIG. 6, a stopper 40 that prevents rotation of the linkage pin 30 is bulged integrally in a gap in the linkage hole 36 provided in the connecting member 27, and the linkage hole 36 is formed. It is formed in a substantially bowl shape. The stopper 40 is formed with a vertical blocking portion 40a with which the linkage pin 30 abuts, and the lower surface is an inclined surface that presses the linkage pin 30 when the connecting member 27 moves backward to act the operating member 23 in the backward movement direction. It is said. The linkage hole 36 has a predetermined gap C below the linkage pin 30 as shown in FIG. 7A, and the lower end action portion of the linkage hole 36 is linked after the connecting member 27 has moved the distance of the gap C. The pin 30 is brought into contact with the pin 30. At this time, the actuating member 23 is regulated in a downward inclined position by a regulating portion (not shown), the linkage pin 30 is located on the side of the stopper 40 in the linkage hole 36, and there is a gap C below, and the upper side of the linkage hole 36. It is located through a slight gap from the upper end. That is, even if an acting force is applied from the movable blade piece 19 side, the relationship is such that the linkage pin 30 stops against the blocking portion 40a of the stopper 40 before the linkage pin 30 comes into contact with the upper end of the linkage hole 36.

  As shown in FIG. 7 (a), the variable winning device 12 having the above-described configuration operates in the state where the solenoid 22 is demagnetized and is not operated so that the plunger 45 is moved downward by the bias of the spring 44, and the connecting member 27 is operated. Is also regulated by the guide pin 37 and kept in the lowered position. Then, the actuating member 23 is moved down by its own weight, so that the movable wing piece 19 stands and is in a closed state in which it is difficult to receive the game ball. At this time, since the stopper 40 is positioned on the rotation track of the linkage pin 30, the movement of the linkage pin 30 is prevented, and the actuating member 23 is not rotated by the action force from the movable blade piece 19 side. The closed state of the blade piece 19 is reliably maintained.

  When the solenoid 22 is excited, the plunger 45 moves up against the bias of the spring 44, and the connecting member 23 slides upward while being regulated by the guide pin 37 as shown by a chain line in FIG. At this time, the stopper 40 moves to a predetermined position where the stopper 40 is detached from the rotation track of the linkage pin 30 to release the rotation prevention of the linkage pin 30. When the linkage pin 30 is released from the rotation prevention of the stopper 40, the lower end action portion of the linkage hole 36 comes into contact with and engages with the linkage pin 30 as shown in FIG. ), The link pin 30 is pushed up, and the link pin 30 rotates to face the stopper 40 without interfering with the stopper 40. Then, the movable wing piece 19 is rotated by a predetermined angle in the opening direction about the rotation shaft 25 via the cam member 26 and is fully opened, so that the game ball is easily won. At this time, the trajectory of the linkage pin 30 has a depression angle relative to a horizontal plane passing through the center of the support shaft 28. In other words, the relationship of the stop position of the linkage pin 30 when the movable blade piece 19 is in the closed state and the open state is such that the left and right linkage pins 30 move gradually as the movable blade piece 19 is opened. It will be closest when the blade 19 is fully open.

  After that, when the solenoid 22 is demagnetized, the plunger 45 returns to the lowered position by the bias of the spring 44, and the operating member 23 moves down by its own weight as the connecting member 23 moves down, and the movable blade is moved via the cam member 26. The piece 19 is moved back to the closed state shown in FIG. Even if the operating member 23 stops returning due to its own weight, the operating pin 23 can be moved downward by pressing the linkage pin 30 with the lower surface of the stopper 40. At this time, since the lower surface of the stopper 40 is an inclined surface that causes the operating member 23 to act in the backward movement direction, the operating pin 23 can be reliably moved back to the downward movement position by pressing the linkage pin 30.

  7 (a), when the movable wing piece 19 is forcibly opened by a fraudulent tool such as a cell plate, the linking pin 30 contacts the blocking portion 40a of the stopper 40. Since the rotating operation of the actuating member 23 is prevented in contact, the actuating member 23 cannot be rotated, and the movable blade 19 is not opened. Further, even if an excessive force is applied to open the movable wing piece 19 and the stopper 40 is forcibly pressed to shift the connecting member 27 laterally to release the lock, the guide pin 37 as a restricting means is used. Is fitted in the guide slot 38, the actuating member 23 does not move, and the locking state of the linkage pin 30 can be reliably held. Therefore, since the movable wing piece 19 is not opened, it is possible to prevent the act of illegally putting the game ball into the winning opening.

  In this embodiment, the stopper 40 is provided in the linkage hole 36 to prevent the linkage pin 30 from rotating, and the movable blade 19 is prevented from unnecessary rotation. It becomes easy. That is, only the shape of the coupling hole 36 of the coupling member 27 needs to be changed, and unnecessary opening operation of the movable blade 19 can be prevented with a simple configuration.

  In the embodiment, the linkage pin 30 is formed in a columnar shape so as to be in line contact with the stopper 40. However, a planar portion that can come into surface contact with the planar blocking portion 40a of the stopper 40 is formed on the linkage pin 30. It may be. By doing in this way, when the solenoid 22 is not driven, the flat surface of the linkage pin 30 is pressed in a lateral direction different from the vertical direction, which is the movable direction of the connecting member 27, in a state where the flat surface of the linkage pin 30 is in surface contact with the blocking portion 40a of the stopper 40. The connecting member 27 is not moved, the actuating member 23 does not rotate, the locking effect is ensured, and the movable blade 19 is not erroneously operated. The planar portion is not necessarily a flat surface, and may be a concave or convex arc surface. At this time, the planar portion of the blocking portion 40a is preferably matched with the shape of the planar portion formed on the linkage pin 30. Further, the linking portion between the actuating member 23 and the connecting member 27 can achieve the same effect even if a linking pin is projected from the linking member 27 and a linking hole for engaging the linking pin is provided in the actuating member 23. it can. At this time, the gap C is preferably provided above the linkage pin 30.

  In the embodiment, the variable winning device 12 provided with a pair of movable wing pieces 19 has been described. However, a pair of movable wing pieces 19 are not necessarily provided, and one movable wing piece 19 is electrically connected via a transmission means. The present invention can be applied even to a variable winning device that opens and closes by a driving force of a driving source. Further, the electric drive source is not limited to the solenoid 22 and may be a forward / reverse motor or a rotary solenoid.

  Further, although the present invention has been described by taking the pachinko gaming machine as an example of the gaming machine in the embodiment, it can be applied to a ball ball gaming machine such as a sparrow ball gaming machine or an arrangement ball type gaming machine using a gaming ball as a gaming medium. is there.
