Description

  The present invention relates to a variable winning device for a gaming machine that is fixed to a gaming board of a gaming machine and has a winning opening for receiving a gaming ball on the gaming board, and a gaming machine using the same.

  In a gaming machine, an accessory having a grand prize opening called an “attacker” (variable prize winning device) is closed so that the horizontal rectangular large prize opening can be opened and closed by a corresponding closing member (opening / closing door). It has a structure. Usually, the opening / closing door is hinged to the front plate or the like of the accessory at both ends of the lower edge. Then, it is displaced by a driving means such as a solenoid between a closed position for closing the big prize opening and an open position for falling from the closed position to the near side (player side) and opening the big prize opening.

Here, since the variable winning device in the gaming machine is directly involved in the payout of the prize ball, it is likely to be a target of fraud (common name, goto action). For example, there is a possibility that a large number of prize balls may be illegally obtained by an illegal act of inserting a foreign object such as a wire into the gaming machine and forcibly moving the rotary wing piece to the open position. In order to prevent such an illegal act, for example, a technique disclosed in Patent Document 1 exists.
Japanese Patent Application Laid-Open No. 2001-224771

  In view of the above-described circumstances, the present invention prevents an illegal force from being applied to a moving body that covers a prize opening of a prize winning device to open a prize opening and illegally acquiring a prize ball. And to make it more fun for players.

Means for Solving the Problems and Effects of the Invention

A first aspect that is a premise for solving the above-mentioned problem is a variable prize device for a gaming machine that is fixed to a gaming board of a gaming machine and has a winning opening for receiving a gaming ball on the gaming board, The winning rate is obtained by straddling the outer gaming area and the inner winning area across the first position where the winning percentage of the game ball is relatively low by covering the winning opening and intersecting the winning opening. A moving body that moves between a relatively higher second position and changes the opening mode of the winning opening, and a first guide section for guiding the movement of the first moving section formed on the moving body And a guide body including a second guide part for guiding the movement of the second moving part formed on the moving body separately from the first moving part; and Less of the first moving part and the second moving part to move between positions A movable body actuator that drives and displaces one of the two, the first moving section draws a locus along the first guide section by the driving displacement of the moving body actuator, and the second moving section to draw a locus along the second guide portion, the moving body may travel displacement between said first and second positions.

In the variable prize winning device for gaming machines according to the first aspect , the moving body has a combined motion (composite motion) in which the trajectory drawn by the first moving portion and the trajectory drawn by the second moving portion are combined. Move and displace between the first position and the second position. In order to move the moving body in the first position to the second position, it is necessary to move the compound trajectory (path) described above, so that it is difficult to perform cheating, and the prize ball is abandoned by cheating. Can prevent unauthorized acquisition of. Moreover, since it is not necessary to incorporate a complicated mechanism for preventing fraud in the transmission system from the moving body actuator to the moving body as in the prior art, fraud can be prevented with a small, compact and simple configuration. The moving object is moved while drawing a composite trajectory, so that the player has a visual interest, and the interest in the game is enhanced.

A second aspect which is a premise for solving the above-mentioned problem is a variable prize device for a gaming machine which is fixed to a gaming board of a gaming machine and has a winning opening for receiving a gaming ball on the gaming board, The winning rate is obtained by straddling the outer gaming area and the inner winning area across the first position where the winning percentage of the game ball is relatively low by covering the winning opening and intersecting the winning opening. A moving body that moves between a relatively higher second position to change the opening mode of the winning opening, and a continuous curved shape for guiding the movement of the first moving portion formed on the moving body A first guide part having a form or a linear form, and a continuous linear form or a curved form for guiding the movement of the second moving part formed on the movable body separately from the first moving part A guide body including a second guide portion; and A movable body actuator that drives and displaces at least one of the first moving portion and the second moving portion to move between the movable body actuator and the second position. While the first moving part draws a locus along the first guiding part and the second moving part draws a locus along the second guiding part, the moving body has the first position and the second position. it may travel displaced between.

The second aspect embodies the first aspect described above, and provides the same operational effects as the first aspect . In particular, since each of the first and second guide portions has a continuous linear form or curved form, the moving body can be moved smoothly.

The present invention for solving the above-mentioned problems is a variable winning device for a gaming machine that is fixed to a gaming board of a gaming machine and has a winning opening for receiving a game ball on the gaming board, and covers the winning opening As a result, the winning percentage is relatively high by straddling the first gaming position where the winning percentage of the game ball is relatively low and the outer gaming area and the inner winning area crossing the winning opening. A moving body that moves between the second position and changes the opening mode of the winning opening, and a curved shape that continues in an arc shape to guide the movement of the first moving portion formed in the moving body. A guide body including a first guide portion having a second guide portion having a continuous linear form for guiding the movement of the second moving portion formed on the moving body separately from the first moving portion; The moving body is moved between the first position and the second position. A moving body actuator that drives and displaces at least the first moving part, and the first moving part draws an arcuate locus along the first guide part by the driving displacement of the moving body actuator, and The moving body is reversibly moved and displaced between the first position and the second position while the second moving portion follows the second guide portion and draws a linear trajectory. It is said.

The present invention further embodies the second aspect described above, and provides the same operational effects as the second aspect . Particularly, since the first guide portion has a curved shape that is continuous in an arc shape, and the second guide portion that is continuous with the first guide portion has a linear shape, the moving body can be moved smoothly. Without impeding this, it is possible to bring a visual interest to the player.

  As a specific configuration, due to the drive displacement of the moving body actuator, the first moving unit moves along the first guide unit and the second moving unit moves along the second guide unit simultaneously, As the first moving unit and the second moving unit move while maintaining a predetermined interval, the moving body can be moved and displaced between the first position and the second position.

  Since the first moving part only needs to be moved along the first guiding part and the second moving part simultaneously along the second guiding part, it is possible to prevent an illegal act with a small and compact configuration.

  The winning opening is arranged to open along the flow direction of the game ball, while the guide body has the second guide portion arranged linearly along the flow direction of the game ball. At the end on the lower side in the direction, it can be connected to the arcuate one end of the first guide portion that forms a convex shape on the lower side in the flow direction.

  Since the first and second moving parts are moved along the corresponding guide parts while maintaining a predetermined interval, the trajectory of the moving body is always constant and the displacement is also smooth. Become. Thereby, the burden on the moving body actuator is reduced, and the size and cost can be reduced.

  Furthermore, the second guide portion may extend tangentially from one end portion of the first guide portion, and may be arranged in parallel to the winning prize opening. In addition, the second guide portion may extend tangentially from one end portion of the first guide portion, and may be arranged in a crossing manner with respect to the winning a prize opening.

  Since the second guide part extends tangentially to the first guide part, the moving body is smoothly moved.

  When the first moving unit moves while drawing an arc-shaped trajectory along the first guide portion so that the moving body is displaced from the first position to the second position, the arc-shaped trajectory is included. In the plane, as the moving velocity component in the flow direction gradually decreases, the moving velocity component in the direction orthogonal to the flow direction gradually increases, and the moving body moves from the state along the flow direction in the first position to the second position. The posture can be changed to a state intersecting with the flow direction at the position.

  Since the posture change of the moving body arranged at the first position and the moving body arranged at the second position is large, a visual interest is brought to the player. Moreover, since the speed of the moving moving body is also displaced, the interest is further enhanced.

  In order for the moving body to reversibly move and displace between the first position and the second position, a central angle in an arc-shaped locus drawn by the first moving part along the first guiding part is two. It can be set to be smaller than a right angle. Further, the connection position between the lower end of the second guide portion in the flow direction and the one end portion of the first guide portion is such that the first moving portion is located when the movable body is displaced to the first position. And when the moving body is displaced to the second position, the second moving part is set at a common stop position, and at the second position, the first moving part is located at the common stop position. It can be stopped in a state of being located on the lower side in the flow direction from the two moving parts.

  By making the central angle of the locus of the first moving part smaller than two right angles, the moving body is smoothly moved between the first position and the second position. In particular, the fact that the central angle is smaller than two right angles is provided on the second position (common stop position) side, so that the first moving portion is avoided from being placed at the thought point, and the movement is smoother. Thus, the burden on the moving body actuator can be reduced.

  The average moving speed when the moving body is displaced from the second position to the first position is adjusted to be larger than the average moving speed when the moving body is displaced from the first position to the second position, The time required for the moving body to move from the second position to the first position can be adjusted to be shorter than the time required to move from the second position to the first position. Thereby, for example, the moving speed when the moving body is displaced from the second position to the first position is made faster or slower than the moving speed when the moving body is displaced from the first position to the second position. You can also

  The moving body arranged at the second position can be quickly moved to the first position.

  The moving body actuator is an electric motor for rotationally driving a protruding portion formed in the first moving portion of the moving body along an arcuate recess formed in the first guiding portion of the guiding body. Rotation for detecting the rotation stop position of the projecting portion that is rotationally displaced by the electric motor, either directly or indirectly in association with the operation of another member, corresponding to the first position and the second position Stop position detecting means may be provided.

  In order to move the moving body, it is necessary to move the moving body against the starting torque of the electric motor. In addition, by controlling the rotation stop position detecting means to operate only when a command from the electric motor is issued, it is possible to detect the movement of the moving body due to fraud, and also to prevent fraud Can do. Note that the above-mentioned “recessed portion” may be in a penetrating state or in a non-penetrating state.

  A center axis attached to the guide body and a radial direction extending from the center of the recess, with the axis of the arcuate recess aligned with the center of the arcuate recess. By holding, while allowing the protrusions to move within the recesses, the rotation arm that can rotate with the separation distance between the center of the recesses and the protrusions as the rotation radius, and the drive rotation of the electric motor A rotation transmission mechanism for transmitting the rotation of the rotation arm, and the drive rotation of the electric motor is transmitted to the rotation arm via the rotation transmission mechanism, and the rotation arm rotates around the axis of the central axis. The projecting portion can be moved along the arc-shaped recess.

  The drive rotation of the electric motor can be efficiently transmitted to the projecting portion of the moving body via the rotation transmission mechanism and the rotating arm, and the above-described complex motion can be easily imparted to the moving body.

  The rotating body transmission mechanism may be a gear transmission mechanism, and the rotating arm may be integrally formed with a gear that rotates about the axis of the central axis.

  The transmission system from the electric motor to the rotating arm can be simplified and miniaturized without hindering the operation of the game ball winning a winning area provided in the moving body.

  As a specific aspect of the moving body, the moving body has a plate-like closing portion that is fitted inside a frame body that forms the winning opening, and can close the winning opening. When the first position is displaced, the winning portion can be closed by closing the inner periphery of the frame.

  The moving body displaced to the first position closes the peripheral edge of the frame that forms the winning opening, so that it becomes difficult to insert foreign objects into the gap between the frame and the moving body. Is prevented.

  When the movable body is displaced to the first position, the outer surface of the closing portion and the outer surface of the frame can be arranged flush with each other.

  A foreign object is not caught on the moving body arranged at the first position, and an illegal act is prevented.

  The movable body has a wall portion that rises from an outer peripheral edge of the closing portion, and the wall portion is configured to cover the frame so that at least the second guide portion is covered when the movable body is displaced to the first position. It can be made to be located between the body winning opening and the inner surface of the frame.

  In order to move the moving body displaced to the first position, a foreign object must be caught beyond the wall of the moving body, making it difficult to perform an illegal act. Further, since the moving body has a box shape, its rigidity is increased and it is difficult to be deformed, and the game balls to be won are prevented from being bitten and spilled.

  And the step part is formed in the thickness direction in the inner periphery of the frame and the outer periphery of the closure part, respectively, and when the movable body is displaced to the first position, the respective step parts are combined. The movable body closes the winning opening in such a manner that the inner peripheral edge of the closing portion and the outer peripheral edge of the frame body overlap each other in the thickness direction. Can do.

  Since the movable body displaced to the first position and the outer peripheral edge portion of the frame body overlap each other and it becomes extremely difficult to insert a foreign object through the gap between them, fraud is prevented more reliably.

  When the moving body is displaced to the first position, the stepped portions of the closing portion are positioned on the winning area side, and the stepped portions of the frame are combined on the gaming area side. Can be made.

  Since the step part of the frame is located on the game area side, which is the outside, and the step part of the plate part is located on the winning area side, which is the inside side, particularly foreign objects such as wire are removed from the outer periphery of the plate part of the mobile body. When a fraudulent act is attempted to release the moving object by inserting it into the wire, the wire etc. reaches the inner side (winning area side) through the frame and plate-like part from the outside side (game area side) It becomes difficult.

Gaming machine of the present invention to solve the above problems, the variable winning device for one of the gaming machine described above, characterized in that fixedly arranged on the game board.

  In the gaming machine according to the present invention, winning balls are prevented from being obtained by fraud, and the moving object is a combined motion (composite motion) in which the trajectory drawn by the first moving unit and the trajectory drawn by the second moving unit are combined. Movement between the first position and the second position. Thereby, a visual interest is brought to the player and an interest in the game is enhanced.

  Examples of the present invention will be described. FIG. 1 is a front view of a pachinko machine 100 according to the present embodiment, FIG. 2 is a perspective view of an attacker 8 when the door 11 is closed, FIG. 3 is a perspective view of the attacker 8 when the door is open, and FIG. FIG. 5 is a rear view of the same.

  First, the entire gaming machine (pachinko machine 100) will be described. As shown in FIG. 1, on the front surface of the game board 1 of the pachinko machine 100, a substantially left half circumference is partitioned by two internal and external launch rails 2, and a substantially circular game area 3 is formed as a whole. Near the center of the game area 3, a liquid crystal display unit 4 is provided for effect display and final display of the result of the first winning / failing lottery (special symbol lottery) performed during the game. Below the liquid crystal display 4 is a narrow opening that makes it difficult to win the game ball B (see FIG. 3), and a wide opening that makes it easy for the game ball B to win. The start chucker 5 whose opening mode changes to an open state (not shown) is arranged. The start chucker 5 also has a function of starting the first winning / losing lottery by winning the game ball B. Below the start chucker 5 is an attacker 6 (large winning opening) that opens the door 6a and makes it easy to win a prescribed number of game balls B when the result of the first winning / losing lottery is a big hit. Has been. The pachinko machine 100 according to this embodiment is called a “double attacker”, and a game base plate 7 separate from the game board 1 is attached to the lower right part of the game area 3. Another attacker 8 is arranged on the base plate 7. In FIG. 1, reference numeral 9 denotes a through gate 9 for starting the second success / failure lottery (normal symbol lottery).

  The attacker 8 of the present embodiment, like the attacker 6 which is a big prize opening, is a first position (closed state shown in FIG. 2) where the open / close door 11 is narrowly opened and the winning rate of the game ball B is relatively low. ) And a second position (open state shown in FIG. 3) that is also wide open and the game ball B has a relatively high winning rate. The attacker 8 includes a drive mechanism 110 for opening and closing the door 11. The drive mechanism 110 will be described. As shown in FIGS. 2 to 5, the game board 7 is provided with a rectangular opening 12. A frame portion 13 having an opening on the lower side is fixed to the peripheral portion of the opening 12 on the back surface portion (back surface portion) of the game board 7. An electric motor 15 (for example, a stepping motor) is attached to the motor bracket 14 projecting from the frame portion 13 toward the back side in such a manner that the axis of the motor shaft 15a extends along the left-right direction of the pachinko machine 100. It has been. A first gear 16 is fitted on the motor shaft 15 a of the electric motor 15. Further, a connecting shaft 17 attached in parallel to the axis of the motor shaft 15a of the electric motor 15 is supported on the motor bracket 14 so as to be rotatable. The first gear 16 is meshed with a second gear 18 (see FIG. 4) fitted in the substantially central portion of the connecting shaft 17. Each third gear 19 is fitted to both ends of the connecting shaft 17, and each third gear 19 is engaged with the fourth gear 21. Each fourth gear 21 is rotatably fitted to each support shaft 23 that protrudes from both side wall portions 22 of the frame portion 13 with their axes extending in the left-right direction. When the electric motor 15 is operated and the motor shaft 15a is rotated in a predetermined direction, the fourth gears 21 are rotated via the first to third gears 16, 18, and 19, respectively. In the present specification, the game board 7 and the frame portion 13 are collectively referred to as “frame body”.

  The groove portions 24 are provided in the pair of side wall portions 22 in the frame portion 13. Since the configuration of the pair of side wall portions 22 is the same except that they are symmetrical, in this specification, the side wall portion 22 on one side (the right side in the rear view of the attacker 8, that is, the right side in the drawing in FIG. 5). Only will be described. As shown in FIGS. 2 to 4, the side wall portion 22 is provided with a substantially J-shaped groove portion 24. The groove portion 24 of the present embodiment includes a first groove portion 24a provided in an arc shape so as to form a convex shape on the lower side of the game ball B in the downward direction of the game ball B, and a front side of the first groove portion 24a. A linear second groove portion 24b is provided that extends in the height direction (that is, parallel to the game board 7) in a continuous state from the end on the (player side). The first and second groove portions 24a and 24b are connected tangentially at their connecting portions. Both the end portion on the back side of the first groove portion 24a and the both end portions of the second groove portion 24b have an arc shape. And the groove width of the 1st groove part 24a is narrower than the groove width of the 2nd groove part 24b. For this reason, the front end portion of the first groove portion 24a is connected to a part of the arc at the lower end portion of the second groove portion 24b. The first and second groove portions 24a and 24b of the present embodiment are both in a through state, but either or both of them may be in a non-through state (concave portion).

  A tongue plate-like arm portion 21a is provided on an inner side surface portion (a portion disposed opposite to the side wall portion 22) of the fourth gear 21, and a cylindrical cylindrical protrusion 25 is provided at an end thereof. . Since the cylindrical protrusion 25 is provided via the arm portion 21a, the rigidity of the cylindrical protrusion 25 is enhanced. The outer diameter of the cylindrical protrusion 25 is slightly larger than the groove width of the first groove portion 24a. The distance R from the axis of the support shaft 23 to the axis of the cylindrical protrusion 25 is equal to the radius from the axis of the support shaft 23 to the center position of the width of the first groove 24a. For this reason, when the 4th gearwheel 21 is rotated, the locus | trajectory of the cylindrical protrusion 25 is formed in circular arc shape in the width center position of the 1st groove part 24a.

  As shown in FIGS. 2 to 5, the attacker 8 includes an opening / closing door 11 that closes the opening 12 of the game board 7 in a normal game state and opens the game ball B in a big hit state so as to be able to win a prize. Yes. The open / close door 11 of the present embodiment is box-shaped. In other words, the front wall 27, the left and right walls (the right wall 28 and the left wall 29 in the front view of the attacker 8), and the back wall are provided at the peripheral edge of the bottom wall 26 in the open state of the door 11. 30 and the winning area A of the game ball B is formed in a portion surrounded by the wall portions 26 to 30. The bottom wall portion 26 has a rectangular plate shape and is slightly smaller than the opening 12 of the game board 7. The bottom surface portion 26a of the bottom wall portion 26 is disposed flush with the game board 7 when the door 11 is closed (see FIG. 2), and protrudes more to the front side than the opening 12 when the door 11 is open. Is arranged (see FIG. 3). The front wall portion 27 is disposed above the opening 12 in a closed state of the opening / closing door 11, and is disposed so as to protrude to the front side from the opening 12 in an opened state of the opening / closing door 11. Similarly, the back wall portion 30 is disposed below the opening 12 when the door 11 is closed, and is retracted behind the opening 12 when the door 11 is open. The rear wall portion 30 is provided in an inclined state with respect to the left and right wall portions 28 and 29 so that the game balls B won in the winning area A can be easily discharged, and the center in the width direction thereof. The part is cut off and a gate 30a is provided. When the open / close door 11 is opened in the big hit state, the game ball B wins the winning area A through the opening 12. The game ball B rolling on the bottom wall portion 26 passes through the gate 30a of the back wall portion 30 and flows down to the ball flow lower portion 31 disposed immediately after the gate 30a. And it counts by passing the passage type sensor 32 attached to the spherical flow lower part 31. FIG. In addition, in FIG. 4, illustration of the bracket which supports the spherical flow lower part 31 is abbreviate | omitted.

  As shown in FIGS. 2 to 4, the left and right wall portions 28 and 29 of the open / close door 11 are each provided with two columnar protrusions (upper protrusions 33) at predetermined intervals in the height direction. And the lower projection 34) are provided with their axes along the left-right direction of the pachinko machine 100. The upper protrusion 33 has an outer diameter slightly smaller than the groove width of the second groove portion 24b, and is fitted into the second groove portion 24b. Further, the lower projection 34 is slightly smaller in outer diameter than the inner diameter of the cylindrical projection 25 provided in each fourth gear 21 and is fitted to the cylindrical projection 25. When the motor shaft 15 a of the electric motor 15 is rotated in a predetermined direction, the fourth gear 21 is rotated via the first to third gears 16, 18, 19 and the connecting shaft 17. Along with this, the cylindrical protrusion 25 provided on the arm portion 21a of the fourth gear 21 is also rotated. At this time, the lower projection 34 of the open / close door 11 is guided by the first groove 24a and moved in an arc shape. At the same time, the upper protrusion 33 of the open / close door 11 is guided by the second groove 24b and moved linearly. As a result, the opening / closing door 11 descends, and the gap between the opening 12 and the front wall portion 27 of the opening / closing door 11 gradually increases (see FIG. 7).

  Here, in the closed state of the door 11, the straight line L <b> 1 that connects the axis of the support shaft 23 of the fourth gear 21 and the cylindrical protrusion 25 is disposed substantially horizontally. When the fourth gear 21 is rotated to the maximum (that is, when the door 11 is fully opened), the lower protrusion 34 of the door 11 is disposed slightly below the extended line of the straight line L1. In FIG. 4, the lower protrusion 34 at that time is indicated by a two-dot chain line. In other words, the angle formed by the straight line L1 and the straight line L2 connecting the axis 23 of the fourth gear 21 and the lower protrusion 34 of the open / close door 11 in the maximum rotation state (the rotation of the lower protrusion 34). The angle θ) is slightly smaller than 180 degrees (two right angles). As a result, the bottom wall portion 26 of the open / close door 11 is disposed in an inclined state in which the front side is slightly higher than the horizontal in the maximum rotation state of the fourth gear 21 (see FIG. 8). As a result, the game ball B won in the winning area A is easy to roll, and the upper protrusion 33 of the open / close door 11 is arranged at the thought point in the maximum rotation state of the fourth gear 21 (that is, a straight line). L1 and L2 are prevented from being in a straight line), and the opening / closing operation of the opening / closing door 11 (especially, the operation when the opening / closing door 11 in the fully opened state is about to close) is smoothly performed.

  In the attacker 8 of the present embodiment, the upper protrusion 33 of the open / close door 11 is the initial position of the cylindrical protrusion 25 of the fourth gear 21 when the fourth gear 21 is fully rotated (the open / close door 11 is fully opened). It is arranged at the position (position of the cylindrical protrusion 25 in the closed state of the open / close door 11). Here, the outer diameter of the upper protrusion 33 of the open / close door 11 is larger than the groove width of the first groove portion 24a. For this reason, the upper protrusion 33 of the open / close door 11 does not enter the first groove 24a in the maximum rotation state of the fourth gear 21. In other words, the first groove portion 24 a functions as a mechanical stopper for the upper protrusion 33 of the open / close door 11. Similarly, the end on the back side of the first groove 24a is also closed to prevent the lower protrusion 34 of the open / close door 11 from moving beyond a predetermined rotation angle θ.

  As shown in FIGS. 2, 3 and 5, the outer surface of the fourth gear 21 on the other side (the left side in the rear view of the attacker 8, that is, the left side in the drawing in FIG. 5) has a semicylindrical shape. The extension part 35 is fixed in an overhanging state. Further, a sensor bracket (not shown) adjacent to the side wall 22 on the other side of the frame 13 is attached to the back surface of the game board 7, and a photosensor 36 is fixed to the sensor bracket. . The extension part 35 of the fourth gear 21 is inserted and arranged between the light emitting part and the light receiving part of the photosensor 36 arranged to face each other. At both ends of the extending portion 35, slits 35a through which the light beam emitted from the light emitting portion of the photosensor 36 can pass are provided. As the fourth gear 21 is rotated, the extending portion 35 is also rotated in the same direction. When the portions other than the slits 35a of the extending portion 35 are disposed between the light emitting portion and the light receiving portion of the photosensor 36, the light beam of the photosensor 36 is blocked. In this state, the operation of the electric motor 15 is continued. When each slit 35a portion of the extending portion 35 is disposed between the light emitting portion and the light receiving portion of the photosensor 36, the light beam of the photosensor 36 passes through the slit 35a. In this state, the operation of the electric motor 15 is stopped. Thus, the photosensor 36 controls the operation (on / off) of the electric motor 15.

  The operation of the photo sensor 36 described above can be associated with the operation of the electric motor 15. For example, it is determined that the photosensor 36 is normal only when the open / close door 11 is opened by the operation of the electric motor 15, and in other cases (for example, foreign matter is caught and the open / close door 11 is opened). In the case of the case, it is assumed that it is a fraudulent act, and the notifying means (not shown) is operated. Thereby, even if the opening / closing door 11 is illegally opened by some means, the illegal act is notified, so that the illegal act can be prevented.

  The operation of the attacker 8 according to the present embodiment will be described with reference to FIGS. 2, 3 and 6 to 8 until the open / close door 11 is changed from the closed state to the open state. 6 to 8, the fourth gear 21 is partially omitted. As shown in FIG. 2 and FIG. 6A, in the normal gaming state (closed state of the opening / closing door 11), the opening / closing door 11 faces the bottom surface portion 26 a of the bottom wall portion 26 on the near side (player side). It is arranged toward the. Since the bottom wall portion 26 is slightly smaller than the opening 12 provided in the game board 7, the front wall portion 27 of the open / close door 11 and the left and right wall portions 28 and 29 are disposed close to the inner surface of the frame portion 13. The Thereby, almost the entire area of the opening 12 of the game board 7 is closed. Since the gaps between the front wall portion 27 and the left and right wall portions 28 and 29 of the opening / closing door 11 and the opening 12 are narrow, it becomes difficult to insert foreign objects into the gaps, and illegal acts are prevented. In addition, the bottom surface portion 26 a of the bottom wall portion 26 of the open / close door 11 is disposed flush with the surface of the game board 7, and there is no portion protruding from the game board 7. For this reason, it becomes difficult to catch a foreign object on the opening / closing door 11, and an illegal act is prevented more effectively. Further, the front side wall portion 27 in the closed state, the left and right wall portions 28 and 29, and the distal end portion of the back wall portion 30 are between the opening 12 of the game board 7 and the inner side surface 13 a on the back side of the frame portion 13. The second groove portion 24b is covered with the frame portion 13.

  In the big hit state, the electric motor 15 is operated by a control means (not shown). As shown in FIG. 6A, the motor shaft 15a is rotated in the direction of the arrow 37, and accordingly, the first gear 16 is rotated in the same direction. Then, the pair of fourth gears 21 is rotated in the direction of the arrow 38 via the second gear 18 (see FIG. 5), the connecting shaft 17 and the third gear 19. At this time, each lower projection 34 provided on the pair of side walls 22 of the open / close door 11 and disposed at the lower end of the second groove 24 b moves downward together with the cylindrical projection 25 of the fourth gear 21. And enters the first groove 24a. Since the lower end portion of the second groove portion 24b has an arc shape, and a part of the arc and the end portion on the near side of the second groove portion 24a are connected in a tangential manner, each lower projection 34 is It smoothly enters the second groove 24b. Here, since each lower projection 34 of the door 11 enters the first groove 24a from the second groove 24b that is wide and linear, the door 11 is quasi-linear in the initial stage. Moved to. As a result, as shown in FIG. 6B, at the initial turning stage of the fourth gear 21, the open / close door 11 is lowered linearly.

  As shown in FIG. 7C, when the fourth gear 21 is further rotated, each lower projection 34 of the door 11 is guided by the first groove 24a to draw an arc-shaped locus. While moving. The distance between the upper and lower protrusions 33 and 34 of the open / close door 11 is always constant, and the upper protrusion 33 of the open / close door 11 is linearly moved while being guided by the second groove 24b. Enters the back side of the game board 7 while gradually tilting. As shown in FIG. 7D, when the open / close door 11 is tilted to a certain level or more, the gap between the opening 12 of the game board 7 and the front wall portion 27 of the open / close door 11 increases, and the game ball B Can win.

  A speed change when each lower protrusion 34 of the open / close door 11 is moved in an arc through the first groove 24a will be described. Until each lower projection 34 is inserted into the first groove 24a until it is arranged at the lowermost end thereof (state (c) of FIG. 7), the lower projection 34 faces downward in the height direction. The velocity component V1 gradually decreases, and the horizontal velocity component V2 also gradually increases. And until each lower projection 34 is arranged in the terminal part from the lowest end part of the first groove part 24a (state of (d) of Drawing 7), the height direction of each lower projection 34 The upward speed component V1 gradually increases, and similarly the horizontal speed component V2 gradually decreases. As a result, a change occurs in the displacement speed of the opening / closing door 11, and the opening / closing door 11 is suddenly displaced or gently displaced, which brings a visual interest to the player. Further, when the open / close door 11 is displaced in the closing direction (the fourth gear 21 is rotated in the direction opposite to the arrow 38), the open / close door 11 can be quickly closed, so that the specified number or more is exceeded. It becomes difficult for the game ball B to win a prize, making it easy and reliable to manage the ball in the game store, and making it difficult for the game ball B to bite.

  As shown in FIG. 8, the bottom wall portion 26 of the open / close door 11 is disposed in an inclined state in which the front side is slightly higher than the horizontal in the maximum rotation state of the fourth gear 21. A slit 35a of the extending portion 35 is disposed between the light emitting portion and the light receiving portion of the photosensor 36, and the light beam emitted from the light emitting portion is received by the light receiving portion. Thereby, rotation of the motor shaft 15a of the electric motor 15 is stopped. In this state, the opening 12 of the game board 7 is opened to the maximum, and the game ball B can easily win the winning area A of the door 11. Since the open / close door 11 has a box shape, the spillage of the winning game ball B is prevented. The game ball B that has won the winning area A rolls on the bottom wall portion 26 of the open / close door 11, passes through the gate 30 a of the back wall portion 30, and flows down to the ball flow lower portion 31. And it counts by passing the passage-type sensor 32.

  When the prescribed number of game balls B are counted, the motor shaft 15a of the electric motor 15 is rotated in the direction opposite to the above by a command from the passing sensor 32. Then, the open / close door 11 is closed by the reverse action.

  Next, an attacker 8 according to another embodiment will be described. In this embodiment, as shown in FIG. 9A, an extending portion 39 that extends below the inner surface of the frame portion 13 is provided on the front side of the lower end portion of the game board 7. It has been. And the upper end part of the opening-and-closing door 11 is excised corresponding to the extension part 39 of the game stand board 7, and the notch part 41 is provided in this excision part. In the closed state of the door 11, the extended portion 39 of the game board 7 enters the cutout portion 41 of the open / close door 11, and the extended portion 39 and the cutout portion 41 overlap in a front view. For this reason, even if it tries to insert a foreign material in the clearance gap between the opening-and-closing door 11 and the opening 12, it is blocked | prevented by the notch part 41. FIG. For this reason, fraud can be prevented more reliably. Note that, as shown in FIGS. 9B and 9C, the opening / closing door 11 is provided at the lower end of the game board 7 because it is once lowered linearly and then placed in an inclined state. There is no possibility that the extended portion 39 interferes with the operation of the door 11.

  A conventional attacker (variable winning device) has a configuration in which a thin door that closes an opening rotates to the near side. For this reason, there is a possibility that an illegal act of forcibly opening the door body by hooking the foreign object inserted from the gap between the door body and the opening to the door body may occur. However, in the attacker 8 of this embodiment, fraud is prevented for the following reason. (1) The open / close door 11 has a box shape, and is provided with a front wall portion 27 having a predetermined height and left and right wall portions 28 and 29. For this reason, the distance from the opening to the tip of each of the wall portions 27 to 29 is increased, and a foreign object is inserted into the gap between the peripheral edge portion of the opening / closing door 11 and the opening 12, and the front wall portion 27 or each of the left and right wall portions is The operation of hooking foreign matter on 28 and 29 is more difficult. (2) Even if a foreign object is caught, the open / close door 11 of the present embodiment is opened by going through a two-stage movement in which the door 11 is linearly lowered along the height direction and then tilted. It is. In order to open the open / close door 11, it is difficult to simply pull the foreign matter caught on the front side, and it is necessary to pull the door on the lower side. And it is very difficult to pull the foreign material downward. (3) Furthermore, the door 11 must be pulled against the starting torque of the motor shaft 15a of the electric motor 15. (4) Even if the opening / closing door 11 is illegally opened by some means, the rotation of the extending portion 35 at that time is detected by the photo sensor 36. Since the rotation at this time is a rotation that does not depend on a command from the electric motor 15, it is regarded as an unauthorized rotation, and an unauthorized action is notified.

  Further, the attacker 8 of the present embodiment has not only the above-described fraud prevention effect but also the following operational effects. (1) The open / close door 11 is opened and closed through two stages of movement, linear movement and arc movement. Moreover, these two movements are continuous. This brings visual interest to the player. (2) The mechanism for realizing the above complicated movement is a combination of one electric motor and a total of six gears 16, 18, 19, and 21. For this reason, the drive mechanism 110 of the attacker 8 is compact and simple, and can be manufactured at low cost. (3) Since the first and second groove portions 24a and 24b are connected continuously and tangentially, the lower projection 34 of the open / close door 11 smoothly moves in and out of the groove portions 24a and 24b. Can be. Thereby, operation | movement of the opening-and-closing door 11 becomes smooth. (4) The open / close door 11 in the fully open state is disposed in an inclined state where the near side is slightly higher than the horizontal, and the rotation angle θ of the lower protrusion 34 of the open / close door 11 is smaller than two right angles. For this reason, it is easy to discharge the game ball B that has won the winning area A, and the arm portion 21a is prevented from being placed at the thought point, and the operation when the door 11 is closed becomes smooth. (5) Since the open / close door 11 is formed in a box shape, its rigidity is high, and smooth displacement that does not twist even if a plurality of game balls B are accommodated is performed. And the load of the electric motor 15 also becomes small. Further, the biting and spilling of the winning game ball B is also prevented.

  In the attacker 8 of this embodiment, the actuator for opening and closing the door 11 is an electric motor 15. However, actuators other than the electric motor 15 (for example, solenoids, air cylinders, etc.) may be used.

  In the attacker 8 of the present embodiment, the drive mechanism 110 is a gear transmission mechanism using the first to fourth gears 16, 18, 19, and 21. As a result, the driving force of the electric motor 15 is reliably transmitted, the driving mechanism 110 is simplified, and the overall size of the attacker 8 is also compact. However, means other than the gear transmission mechanism (for example, a winding transmission mechanism using a belt, a chain, a wire, a rope, or the like, or a contact transmission mechanism using a friction wheel) may be used.
