Description

  The present invention relates to a variable prize device for a gaming machine and a gaming machine.

  Conventionally, a ball receiving member (rotating body) for guiding a pachinko ball (game ball) to the ball entrance to the mounting board (base plate) having a ball entrance (winning entrance) opened horizontally by the rotation of the motor. By rotating, the pachinko ball can be received when the ball receiving member passes the front side of the mounting substrate, while the ball receiving member passes the back side of the mounting substrate (when not on the front side). ) Is a prize-winning device configured so as not to accept pachinko balls (see Patent Document 1).

Japanese Patent No. 2813739

  By the way, the ball receiving member has a fan shape in a plan view, and appears and disappears from the front surface of the mounting board through an outer passage formed in the mounting board by horizontal rotation. Thus, when the ball receiving member emerges from one outer passage part and rotates horizontally so as to enter the other outer passage part, particularly when its end part tries to enter the outer passage part (back side). In addition, there is a risk of causing a ball bite.

  Further, when the ball receiving member passes through the front surface side of the mounting substrate, it is in a state of projecting forward from the mounting substrate, so the distance between the ball receiving member and the front glass is substantially the same as the diameter of the pachinko ball. There is a risk that if a pachinko ball falls in this region, the ball bites (ball clogging).

  However, it is conceivable to increase the gap distance between the mounting board (game board) and the front glass as a measure not to cause the biting of the ball, but the flow of the pachinko ball deteriorates and the game is hindered. . Alternatively, it is conceivable to make the ball receiving member small, but there is a dilemma that the function of the ball receiving member is greatly impaired.

  The present invention has been made in view of the above circumstances, and in the case where a rotating body that rotates horizontally is provided, a variable winning device for a gaming machine that can suppress the biting of the ball on the front glass without impairing the function of the rotating body. And providing a gaming machine using the same.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the variable prize winning device for gaming machines of the present invention is:
A variable prize device for a gaming machine fixed to a gaming board of a gaming machine,
A base plate having a winning opening on the front side for receiving game balls on the game board;
It has a ball introduction port that allows game balls to be introduced into the winning opening and enables winning, and can be rotated around the rotation axis arranged in the vertical direction so as to straddle from the back side of the base plate to the front side above the winning opening. So that a ball introduction port is located on the front side in a predetermined rotation angle range and a game ball can be won, and a regulation state in which the winning is restricted in the remaining rotation angle range is formed. A rotating body that rotates and changes the position of the ball inlet;
A rotating body actuator that is fixedly supported by the base plate and rotationally displaces the rotating body so as to form an open state and a restricted state;
A front surface which is fixedly supported on the front surface side of the base plate, avoids interference with the rotation region of the rotating body and protrudes forward on the front surface side of the base plate, and is located on the front surface side of the rotation region and the game board A closing member for closing between the glass,
Equipped with a,
When the closing member draws a straight line in the vertical direction passing through the winning opening as viewed from the front, it is formed in a form inclined so that the game ball rolls toward the side away from each other with the straight line as a boundary,
The rotating body, in a portion projecting from the base plate to the front side in a predetermined rotation angle range, forms a collar portion that is inclined to the side in the form of a mountain when viewed from the front,
The ball introduction port is composed of an opening formed by cutting out the collar portion, and the collar portion of the portion having the ball introduction port is inclined to the side with the ball introduction port as a top portion. To do.

  According to the present invention, the variable winning device for a gaming machine spans from the back side of the base plate to the front side and changes the position of the ball inlet to rotate the game ball winning conditions (for example, open state and restricted state). And a closing member for closing the space between the rotating region of the rotating body and the front glass. And this closing member has the form which protrudes ahead while avoiding interference with the rotation area | region of a rotary body seeing from the top. As a result, the closing member closes the gap between the rotating body and the front glass, so that the game ball does not enter the gap and suppresses or prevents the occurrence of ball biting (ball clogging) between the rotating body and the front glass. can do. That is, even if the game ball tries to enter the gap, it cannot hit the closing member and even flow down the gap.

  The closing member may be formed in such a manner that when a straight line passing through the winning opening as viewed from the front is drawn, the game ball is inclined so as to roll toward the side away from the game ball on both sides with the straight line as a boundary. it can. According to this, since the closing member is inclined to both sides with the winning opening as a boundary, the game ball rolls along the inclination when it rides on the upper surface of the closing member, and the game ball Can be prevented from staying in.

  In addition, the variable winning device for gaming machines includes a front decoration portion that is fixedly supported by the base plate and covers the winning opening from the front side, and the closing member is integrally formed as a part of the front decoration portion. By forming the closing member by partially using the front decoration portion located on the front side, the player can be placed in a natural manner without feeling uncomfortable. Furthermore, it can arrange | position so that interference with the rotation area | region of a rotary body can be easily avoided by setting it as a part of front side decoration part.

  The rotating body can form a flange portion that inclines to the side in a shape that forms a mountain shape when viewed from the front in a portion that protrudes from the base plate to the front surface side within a predetermined rotation angle range. Further, the ball introduction port is configured by an opening formed by cutting out the collar portion, and the collar portion of the portion having the ball introduction port is inclined to the side with the ball introduction port as a top portion. be able to. According to this, since the heel part protruding to the front side of the base plate is inclined in the shape of a mountain, the game ball rolls along the inclination when riding on the upper surface of the heel part. It is possible to prevent the sphere from staying.

  In addition, the rotating body has a flange portion that protrudes from the base plate to the front surface side within a predetermined rotation angle range, and is arranged so that the closing member has the same height as the flange portion.

  Specifically, when the collar portion is in a rotation stopped state on the front surface side of the base plate, the inclined surface of the closing member coincides with the inclined surface of the collar portion or an extension thereof when viewed from the front. That is, in a predetermined rotation angle range in which the rotating body rotates, the inclined surfaces formed in the hook-shaped chevron shape can respectively coincide with two intersecting planes including the closing member. According to this, since the adjacent heel part and the closing member form the same plane and become a rotation stop state (because they coincide on the same plane), when the game ball rides on the heel part or the closing member It is guided smoothly downward (side) without staying in the water. In addition, the game ball can be bounced with natural movement.

Therefore, in order to solve the above problems, the gaming machine of the present invention is:
The variable winning device for gaming machine as described above is fixedly arranged on the gaming board.

  Thereby, while being able to prevent the ball biting between the front glass and the rotating body, it is possible to realize a gaming machine having an interesting board surface configuration.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view illustrating a gaming machine equipped with a variable winning device for gaming machines according to the present invention, FIG. 2 is a perspective view and a plan view showing an example of a variable winning device for gaming machines in a big hit state, and FIG. 4 is a cross-sectional view taken along line AA and BB, FIG. 4 is a perspective view and plan view showing an example of a variable prize winning device for a gaming machine in a normal state, and FIG. 5 is a cross-sectional view taken along line CC in FIG. It is D sectional drawing.

  As shown in FIG. 1, on the board surface 2a (front surface) of the game board 2 of the pachinko machine 1 (game machine), a substantially left half circumference is partitioned by two inner and outer firing rails 2b, and a game area 2c having a substantially circular shape as a whole. Is formed. A liquid crystal display unit 3 is mounted at the center of the game area 2c, and a winning device 4 (a variable winning device for gaming machines) is arranged at the lower right of the liquid crystal display unit 3 (lower right of the gaming area 2c).

  As shown in FIGS. 2 and 3, the winning device 4 includes a base plate 10 fixed to the game board 2, a rotating body 20 attached so as to straddle the back side of the base plate 10 from the front side, and a rotating body. 20 includes an electric motor 30 (rotating body actuator) that rotates and displaces 20, and a front decoration portion 40 that is fixedly supported on the front side of the base plate 10.

  As shown in FIG. 3 (b), the base plate 10 has a circular shape when viewed from the front, and has a winning opening 11 for receiving a game ball on the game board 2 from the front side to the back side, and the winning opening A horizontally long opening 12 having a rectangular shape in which the rotating body 20 is disposed is formed above 11. In addition, on the back side of the base plate 10, an onion 13 that is integrally and continuously connected to the winning opening 11 and extends rearward is formed (see FIG. 3A).

  A housing 50 to which the electric motor 30, the proximity switch 31, the photo sensor 32, and the like are attached is fixed to the tip of the onion 13 (back side of the base plate 10). The proximity switch 31 is a non-contact type detection sensor for detecting that the game ball of the game board 2 has won the winning opening 11, and detects the game ball guided by the onion 13. The photosensor 32 is for recognizing the rotational position of the rotating body 20 as will be described later. Specifically, in the photosensor 32, the light emitting portion and the light receiving portion are arranged facing each other at the inner and outer positions sandwiching the extending portion 23b extending downward in a skirt shape formed in the rotating body gear 23. . Then, the extending portion 23b having the notch 23c rotates around the axis O1 so as to block the light beam from the light emitting portion to the light receiving portion, thereby recognizing the rotational position of the rotating body 20.

  Returning to FIG. 2, the rotator 20 has a ball introduction port 20 a that allows a game ball to be introduced into the winning port 11 and allows winning, and is attached to be rotatable about a rotation axis O <b> 1 arranged in the vertical direction. . The rotator 20 has an open state (see FIGS. 2 and 3) in which a ball introduction port 20a is positioned on the front side of the base plate 10 and allows a game ball to be won in a predetermined rotation angle range, and the rest (position on the front side). The position of the ball inlet 20a is rotationally changed so as to form a regulation state (see FIGS. 4 and 5) that regulates the winning in the rotation angle range of “No”.

  In addition, the rotating body 20 is inclined to the side (for example, an inclination angle θ / 2) in a shape that forms a mountain shape when viewed from the front in a portion that protrudes from the base plate 10 to the front side within a predetermined rotation angle range. 21 is formed (see FIG. 5B). The ball introduction port 20a is configured by an opening formed by cutting off the flange 21. That is, the notched flange portion 21 is configured on both sides of the sphere introduction port 20a as the sphere introduction port forming portions 21a and 21a that form the sphere introduction port 20a. In addition, in the ball introduction port forming portions 21a and 21a (the flange portion 21), the ball introduction port 20a is inclined to the outer side (see FIG. 3B).

  Specifically, as shown in FIG. 3A, the rotating body 20 includes a support shaft insertion hole 20 b formed in the rotating body 20 and a supporting body formed in a rotating body gear 23 that rotates integrally with the rotating body 20. The support shaft 22 is inserted into and supported by the shaft insertion hole 23a. That is, the rotating body 20 and the rotating body gear 23 are supported so as to be rotatable around the rotation axis O <b> 1 of the support shaft 22. At this time, the lower end of the support shaft 22 is held by the housing 50 and the upper end is held by the support shaft holding portion 51. Therefore, when the output shaft of the electric motor 30 rotates, the output gear 30a rotates and power is transmitted to the rotating body gear 23, so that the rotating body 20 is rotationally displaced (see FIG. 2B). The positioning of rotation and rotation stop of the rotating body 20 is performed by the photosensor 32 via the extending portion 23b of the rotating body gear 23.

  Further, as shown in FIG. 2, in the rotating body 20 according to the present embodiment, the upper wall 20c has a circular shape in plan view (including the flange portion 21), and a predetermined angle range (for example, 270) of the upper wall 20c. A peripheral wall 20d extending downward from the outer peripheral edge in a range of degrees) is formed. A side wall 20e is formed along a straight line connecting both end portions of the peripheral wall 20d. Further, the peripheral wall 20d and the side wall 20e are extended corresponding to the height of the opening 12 formed in the base plate 10. Therefore, the outer peripheral edge (circumferential wall 20d) of the upper wall 20c is disposed so as to be close to the opening 12, and the rotating body 20 is formed so as to always straddle from the back side to the front side of the base plate 10.

  By the way, as for the rotary body 20, the collar part 21 is formed in four places in the circumferential direction, and one of them constitutes the ball introduction port forming portions 21a and 21a to form the ball introduction port 20a. And the side wall 20e is formed corresponding to the ball inlet 20a. Thereby, when the ball introduction port 20a is located on the front side of the base plate 10 (such as a big hit), the side wall 20e becomes a form that closes the opening 12, and the game ball does not enter the inside of the rotating body 20, The game ball can be guided to the winning opening 11 without any problem (see FIG. 3B).

  In the present embodiment, four flange portions 21 are provided in the circumferential direction, and the portion surrounded by the flange portion 21 of the upper wall 20c is formed in a square shape. However, the present invention is not limited to this. Various setting changes can be made according to the size of the diameter of the rotating body, the distance of the rotation axis O1 from the base plate, and the like.

  Subsequently, the front decoration part 40 is fixedly supported on the base plate 10 so as to cover the winning opening 11 from the front side. As shown in FIG. 2 (b), the front decoration part 40 is integrally formed as a part of the front decoration part 40 and at least a part of the rotation area of the rotating body 20 and the front glass located on the front side of the game board 2. A closing portion 41 (closing member) for closing the gap with G is provided. Further, the closing portion 41 has a form that protrudes forward while avoiding interference with the rotating region of the rotating body 20 when viewed from above. That is, the closing portion 41 is formed by cutting out from the base plate 10 side in an arc shape so as to surround a part of the rotation region of the rotating body 20 protruding from the base plate 10 from the outside.

  Thereby, there is almost no space between the rotating body 20 (the flange portion 21) protruding from the base plate 10 and the glass surface G, and even if the game ball P flows down, it hits the closing portion 41 and is caught by a ball (ball clogging). Is suppressed or prevented. Further, since the closing portion 41 surrounds the rotation region of the rotating body 20 on the front side of the base plate 10, the distance between the base plate 10 and the closing portion 41 is narrow, and the ball introduction port 20a (ball introduction port formation) When the portion 21 a) enters the back side of the base plate 10, the occurrence of ball biting (ball clogging) is suppressed or prevented.

  In addition, the closing portion 41 is inclined so as to roll toward the side where the game ball moves away on both sides with the vertical line L passing through the winning opening 11 as seen from the front (for example, an inclination angle θ / 2). It is formed along a line forming a mountain shape.

  The front decoration part 40 is integrally formed with a front decoration part 42 parallel to the base plate 10 and a ball receiving part 43 for guiding a game ball introduced from the ball introduction opening 20a to the winning opening 11. In addition, a window portion 42 a is formed in the front decoration portion 42.

  As described above, in the winning device 4, since the rotating body 20 rotates (horizontal rotation) around the axis O <b> 1, the flange portions 21 formed side by side in the circumferential direction and the closing portion 41 formed on the front decoration portion 40. Are the same height. The inclined surface of each collar part 21 and the inclined surface of the closing part 41 are both set to have the same inclination angle and inclination direction. That is, as shown in FIG. 3B and FIG. 5B, when the collar portion 21 is in a rotation stopped state on the front surface side of the base plate 10, a form that forms a mountain shape of the collar portion 21 when viewed from the front is formed. The inclined surface which forms the mountain-shaped form of the closing part 41 corresponds on the inclined surface or its extension. That is, the inclined surfaces of the flange portions 21 formed at four locations in the circumferential direction of the rotating body 20 coincide with the inclined surfaces of the closing portion 41 when the rotation is stopped on the front surface side.

  Next, the operation of the winning device 4 having such a configuration will be described. In the winning device 4, when a predetermined condition (for example, when a lottery is won), the electric motor 30 is energized, the rotating body 20 is rotationally displaced, and the ball introduction port 20 a is arranged on the front side so that the winning port 11. Open. When the predetermined condition (when the specific gaming state is finished), the electric motor 30 is energized, the rotating body 20 is rotationally displaced, the ball introduction port 20a is arranged on the back side, and the winning port 11 is set. Let it be regulated.

  First, the winning device 4 is formed with a ball introduction port 20a so as to form a restricted state that restricts the winning of the game ball P, as shown in FIGS. The notched collar 21 is located on the front side, and the rotating body 20 is stopped rotating. In other words, the sphere introduction port 20a is positioned on the back side of the base plate 10, and the rotating body 20 stops rotating. Therefore, since the heel portion 21 is disposed adjacent to the closing portion 41 above the winning opening 11 (because it is covered by the front decoration portion 40 and the heel portion 21), the game ball P is on the side as indicated by the arrow. It is in a state where winning is impossible.

  When the electric motor 30 is energized from this normal state, the rotating body 20 is rotated via the output gear 30 a and the rotating body gear 23. As a result, as shown in FIGS. 2 and 3, the ball introduction port 20a is rotationally displaced until it is located on the front side. Thereby, the winning device 4 can be used as a big hit state in which the game ball P can be introduced from the ball introduction port 20a.

  As described above, since the outer peripheral edge of the rotating body (excluding the ball introduction port portion) is always rotated in close proximity to the closing portion, the closing portion is not affected at any rotation stop position during normal game or specific game. The space between the rotating body and the front glass can be easily closed.

  The present invention is not limited to the above-described embodiments, and various modifications based on the knowledge of those skilled in the art can be made according to the purpose and application without departing from the spirit of the claims.
