Some members tilt the member to open the ball entrance to make it easier to enter the ball. However, when the solenoid is not activated, this variable 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 door member, It is a structure that can open the member forcibly. For this reason, there have been a number of fraudulent acts that unfairly win prize balls, and therefore a variable prize winning device that can prevent fraudulent acts without opening the door member even if the door member of the variable prize winning device is opened from the outside has been proposed. (For example, refer to Patent Document 1).

JP 2000-176098 A

  However, the variable prize winning device described in the above-mentioned patent document is locked to hold the door member in a vertical state against a force that attempts to tilt the door member illegally when the door member is in a vertical state. Since the lever is provided separately, there are problems that the number of parts is increased, the cost is increased, the structure is complicated, and the assembly work is complicated.

  The present invention has been made in order to solve the above-mentioned problems, and the door member does not tilt even if it attempts to open the ball entrance from the outside illegally with a simple configuration, and it is possible to prevent illegal acts reliably. It is an object of the present invention to provide a variable prize winning device and a gaming machine using the same.

  In order to achieve the above object, according to the first aspect of the present invention, there is provided a ball entrance in which a plurality of game balls can be won on a base plate, and a door member for opening and closing the ball entrance is provided substantially horizontally. The door member is in an open state in which a game ball can enter and a closed state in which a game ball cannot enter through a transmission means that is pivotally supported by a shaft and transmits a driving force of an electric drive source. The variable prize winning device is a variable prize-winning device, wherein the door member is provided with an operation portion linked to the transmission means at a position eccentric to the rotation axis of the door member, and the transmission means is movable with a predetermined stroke alone with respect to the operation portion. An engaging portion that engages with a gap to be obtained, and a locking means that is positioned on a rotation path of the operation portion when the electric drive source is not driven and prevents the operation portion from rotating, When the electric drive source is driven, the transmission means moves forward in a single stroke. It rotates the operating portion after the locking means is disengaged from the rotation trajectory of the operating unit, characterized in that so as to open the door member. The “electric drive source” here is a general term for actuators that operate the movable body in response to an electrical signal. For example, a motor and a solenoid correspond to the electrical drive source.

  With the configuration described above, when the door member is in the closed state with the electric drive source not driven, the rotation of the operation portion is locked by the locking means to prevent the door member from rotating in the opening direction. Then, when the electric drive source is driven and the transmission means is movable by a predetermined stroke alone, the lock means moves to a predetermined position and is disengaged from the rotation path of the operation part, thereby avoiding interference between the operation part and the lock means. Then, the rotation prevention of the operation part is released, and then the engagement part contacts and engages the operation part to rotate the door member. In other words, the door member can be rotated only by the driving force of the electric drive source. By configuring in this way, even if an unnecessary acting force in the opening direction is applied to the door member in the non-driven state of the electrical drive source, the operation unit is not locked by the locking means and the door member is not opened. .

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the engaging portion is formed with a predetermined gap and the locking means is provided in the engaging portion. The engaging portion may be formed, for example, in a substantially U shape in side view with a predetermined gap.

And a variable winning device for changing the door member between an open state in which a game ball can enter and a closed state in which the game ball cannot enter via a transmission means for transmitting a driving force of an electric drive source. The transmission means includes a connecting member connected to the electrical drive source, and an operating member linked to the connecting member and moving the door member in conjunction with the door member. A linkage portion having a predetermined gap is provided, and an operating portion linked to the linkage portion is provided on the operating member, and the linkage portion is provided with a gap that is movable by a predetermined stroke alone and engages with the operating portion. And when the electric drive source is not driven, Locking means is provided on the track where the moving part is movable to prevent rotation of the actuating part, and the locking means is operated by a single stroke of the connecting member when the electric drive source is driven. The operating member is moved after being separated from the track, and the door member is opened. For example, the connecting member is movable in the same direction as the driving direction of the electric drive source, and the operating member is moved so as to change the driving direction of the connecting member to a different movement direction, and the driving force of the electric drive source is changed to the door. What is necessary is just to make it transmit to a member.

  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, it is preferable that a planar blocking portion is formed on the locking means and a planar portion capable of being in surface contact with the blocking portion is formed on the operation portion or the operating portion. As a result, the acting force acts in a direction different from the moving direction of the transmission means in a state where the planar portion of the operation portion or the operating portion is in surface contact with the planar blocking portion when the electric drive source is not driven. There is no malfunction, and the locking effect is ensured. Here, the planar portion includes a flat surface or a gentle arc surface.

  In addition, it is preferable that a portion of the lock means facing the backward movement direction is an inclined surface facing the operation section or the operation section, and the operation section may be guided in the backward movement direction when the transmission means is moved backward. .

  The engaging portion and the linking portion may be formed in a hole shape having a predetermined gap, and a lock unit may be provided in the gap.

  According to the variable winning device according to the present invention, the door member is not opened even if an attempt is made to open the door member by using an unauthorized tool such as a piano wire or a cell board when the electric drive source is not driven. It is possible to reliably prevent fraud that is acquired in the future.

  In addition, it is possible to cope with a slight change in design of an existing operating member, and it is possible to prevent fraudulent acts while ensuring normal operation of the variable winning device with a simple configuration. Therefore, the cost can be reduced.

  Hereinafter, an embodiment of a pachinko gaming machine as a gaming machine of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko gaming machine provided with a variable winning device according to the present invention, and FIG. 2 is a cross-sectional plan view showing the variable winning device partially cut away. The pachinko gaming machine 100 includes an outer frame 1 for mounting on an installation frame of a game hall, and an inner frame 2 is rotatably provided on one front side of the outer frame 1 via a hinge mechanism, and the other side is a cylinder. It is locked so that it cannot be opened and closed by a lock mechanism such as a lock. A game board 4 is mounted on the inner frame 2, and a front board 6 including a transparent board that covers the front of the game board 4 is rotatably provided. Further, the inner frame 2 positioned below the front plate 6 is provided with a supply tray 7 for storing game balls and supplying hitting balls to the launching unit, and a storage tray 8 for storing surplus balls. An operation handle 9 for adjusting the resilience of the hit ball is provided on the right side of the storage tray 8.

  The game board 4 is formed in a substantially square shape, a substantially circular game area 4a is formed between the transparent plate of the front plate 6 by a guide member having a predetermined width, and the variable display device 11 is provided in a substantially central area thereof. Provided. A start winning opening 12 for changing the image of the variable display device 11 is provided below the variable winning device 11, and a variable winning device 13 according to the present invention is provided below the start winning opening 12. In addition, an out port 10 through which game balls that have not become winning balls flow out as out balls is provided at the lowermost end of the game area 4a. The variable winning device 13 wins a game ball in the start winning port 12 and detects the passing of the game ball by a detection switch (not shown), and a lottery is performed, and the result is a variable display device 11 under a predetermined condition such as “winning”. A specific symbol is displayed on the display portion of the player, and the player is set to drive after notifying the player of “winning”.

  In the variable winning device 13, a solenoid 19 is assembled as an electric drive source behind a base plate 15 in which a ball inlet 16 into which a plurality of game balls can be won is opened in a horizontally long shape, and the ball inlet 16 is closed on the front surface. A frame body 18 on which a rectangular door member 17 is pivotally supported so as to be opened and closed is provided. The driving force of the solenoid 19 is transmitted to the door member 17 via the transmission means, and is displaced between the first state in which the door member 17 is opened and the second state in which the door member 17 is closed by driving the solenoid 19.

  The door member 17 is provided with flanges 20 that are bent at right angles on both side edges, and located at the lower edge of the ball inlet 16, parallel to the base plate 15 below the front part of the flange 20, and horizontally. Is provided with a rotating shaft 21. On the outer side of one of the flanges 20 (on the left side in the front view in the embodiment), there is a shaft-like engagement protrusion 22 as an operating portion that is eccentric with the rotation shaft 21 and is linked to the transmission means at a position below the rotation shaft 21. Projected. The door member 17 is set so that the center of gravity is positioned on the side of the engagement protrusion 22 in the standing state and is biased in the closing direction, and the position of the center of gravity is biased in the opening direction in the tilted state. The door member 17 is urged in the opening direction or the closing direction by 22 straddling a horizontal line passing through the rotation shaft 21.

  The solenoid 19 is horizontally disposed on the frame 18 so as to be substantially orthogonal to the base plate 15, and when the variable winning device 13 is mounted on the game board 4, the plunger 24 mounted with the spring 23 moves forward and backward. It is provided to move.

  The transmission means for transmitting the driving force of the solenoid 19 to the door member 17 links the connecting member 25 provided on the flange at the front end of the plunger 24 and the operating member 26 linked to the door member 17 as shown in FIG. Configured. The connecting member 25 moves linearly in the horizontal direction in the same direction as the driving direction of the solenoid 19 in conjunction with the plunger 24 that moves forward and backward by driving the solenoid 19, and the actuating member 26 moves the connecting member 25 in the vertical direction. The door member 17 is opened and closed by converting into rotational motion. Specifically, the connecting member 25 is formed with an interlocking piece 25b in a substantially L shape in plan view perpendicular to the mounting portion 25a fitted to the flange of the plunger 24, and a door member serving as a linking portion on the upper side of the interlocking piece 25b. A connecting pin 27 parallel to the seventeen rotating shafts 21 is projected, and a longitudinal hole 35 in the front-rear direction is formed at the upper and lower intermediate portions. The actuating member 26 is rotatably provided in the vertical direction with a support shaft portion 28 parallel to the rotation shaft 21 of the door member 17 supported by the frame body 18. The support shaft portion 28 is loosely inserted into the elongated hole 35 of the connecting member 25 and serves as a guide when the connecting member 25 advances and retreats. In addition, an operating groove 29 that is open above the support shaft portion 28 and is connected to the connection pin 27 of the connection member 25 and that is openly fitted to the connection pin 27 is provided. An engagement portion 30 having a U-shape in a side view having a predetermined gap C <b> 1 is formed by the upper and lower engagement pieces that engage with the mating protrusions 22. The interval between the upper engagement piece and the lower engagement piece of the engagement portion 30 is provided with a gap C2 that can move with respect to the engagement protrusion 22 by a predetermined stroke alone, and is engaged when the solenoid 19 is not driven. A stopper 31 serving as a locking means that is positioned on the rotation track of the protrusion 22 and prevents the engagement protrusion 22 from rotating is provided to bulge into the gap C <b> 1 of the engagement portion 30. That is, when the operating member 26 moves independently only by the stroke of the gap C <b> 2, the stopper 31 is disengaged from the rotation track of the engaging protrusion 22, and the engaging portion 30 engages with the engaging protrusion 22. A space portion is formed so that the engaging protrusion 22 can face below the stopper 31 when the operating member 26 is operated so that the member 17 can be opened and closed, and the shape of the gap C1 of the engaging portion 30 has a bowl shape. Further, the stopper 31 is formed with a planar blocking portion 31a with which the engagement protrusion 22 abuts. The engaging protrusion 22 is always located in the gap C1 of the engaging portion 30 so that the engaging protrusion 22 can be operated reliably. Further, by restricting the distance in which the connecting member 25 advances and retreats, the rotation range of the operation member 26 is limited, and the operation member 26 is excessively rotated excessively and the engagement portion 30 and the door member 17 are engaged. The linkage with the mating protrusion 22 is prevented from being removed.

  The frame body 18 is divided into upper and lower parts, and the rotary shaft 21 of the door member 17 and the support shaft portion 28 of the operating member 26 are sandwiched between the bearing portions of the upper and lower frame bodies, so that the door member 17 and the operating member 26 rotate. It is supported movably (see FIG. 2). In addition, a winning area 18a provided with a winning opening for a game ball received by the door member 17 and a storage section 18b in which an operating member 26 for converting the advance / retreat movement of the solenoid 19 into a rotational movement is stored are formed. Yes. Note that the frame 18 may be divided into front and rear, and the front half may be formed integrally with the base plate 15.

  In the variable winning device 13 having the above-described configuration, the engagement protrusion 22 is downward from the imaginary straight line connecting the rotation shaft 21 of the door member 17 and the support shaft portion 28 of the operation member 26 in order to ensure the locking effect. When the door member 17 is opened, the engagement protrusion 22 moves toward the virtual straight line. That is, as shown in FIG. 5, the distance L1 from the center of the rotating shaft 21 of the door member 17 to the contact point P between the engaging protrusion 22 and the stopper 31 and the center of the support shaft portion 28 of the operating member 26 are engaged with the engaging protrusion 22. And the sum of the distance L2 to the contact point P between the stopper 31 and the stopper 31 is set to be larger than the linear distance L connecting the center of the rotating shaft 21 and the center of the support shaft portion 28 of the actuating member 26. The blocking portion 31 a of the stopper 31 is provided so that the direction of the acting force from the door member 17 in P is directed downward from the support shaft portion 28. For this reason, when the door member 17 is forcibly opened, the operation of the engaging protrusion 22 is blocked by the stopper 31 of the operating member 26, and the operating member 26 cannot be moved by the acting force from the door member 17. 17 does not open unnecessarily.

  Next, the operation of the variable winning device 13 having the above configuration will be described. In the normal state in which the solenoid 19 is demagnetized, the plunger 24 is in the advanced position by the bias of the spring 23 as shown in FIG. 4 (a), so that the connecting member 25 moves forward and the operating member 26 rotates downward. The stopper 31 is located close to the engaging protrusion 22 and is located on the rotation track of the engaging protrusion 22. At this time, the rotation operation of the engagement protrusion 22 is blocked by the stopper 31, so that unnecessary rotation of the door member 17 is blocked, and the door member 17 maintains a standing state and does not accept a game ball. Yes.

  When the solenoid 19 is excited under a predetermined condition, the plunger 24 moves backward against the bias of the spring 23, and the operating member 26 is supported by the support shaft portion 28 by the engagement of the connecting pin 27 and the operating groove 29 of the connecting member 25. Rotate upwards around the center. Accordingly, when the stopper 31 moves away from the engagement protrusion 22 and moves to a predetermined position, as shown in FIG. To release. Then, when the engagement protrusion 22 is released from the rotation prevention of the stopper 31, the engagement portion 30 comes into contact with and engages with the engagement protrusion 22, and pushes up the engagement protrusion 22, as shown in FIG. As shown, the engaging protrusion 22 is rotated so as to face the lower side of the stopper 31, and the engaging protrusion 22 is rotated to a predetermined position (for example, the height position of the engaging protrusion 22 exceeds the height position of the rotating shaft 21). When the door member 17 is moved, the door member 17 rotates in the opening direction about the rotation shaft 21 by its own weight. Then, as shown in FIG. 4C, the door member 17 is in a fully open state where a game ball is easy to win. Note that the engagement protrusion 22 is below the stopper 31 during the period from when the door member 17 is rotated by the swinging motion of the operation member 26 until the door member 17 is changed from the closed state to the open state shown in FIGS. Therefore, it does not interfere with the blocking portion 31a of the stopper 31.

  When the solenoid 19 is demagnetized and released after a predetermined time has passed or a predetermined number of balls have been won at the ball inlet 16, the plunger 24 returns to the forward position due to the bias of the spring 23, and the connecting member 25 returns. When the engagement protrusion 22 is pressed downward by the lower surface of the stopper 31, the door member 17 starts to move backward, and when the engagement protrusion 22 is rotated to a predetermined position (for example, the same height position as the rotation shaft 21). The weight of the door member 17 returns to the closed state shown in FIG. 4A, and the engagement protrusion 22 moves to the side position of the stopper 31 and is prevented from rotating.

  On the other hand, in the closed state of the door member 17 shown in FIG. 4 (a), a forcible operating force that tries to forcefully open the door member 17 by hooking an unauthorized tool such as a piano wire or a cell board on the upper end of the door member 17. Even if the engagement protrusion 22 starts to rotate around the rotation shaft 21, the engagement protrusion 22 contacts the blocking portion 31 a of the stopper 31. At this time, since the acting force works toward the support shaft portion 28, the engagement protrusion 22 is prevented from rotating in the opening direction of the door member 17 and cannot rotate, and the door member 17 does not open. The act of winning a game ball at the ball entrance 16 can be prevented. Further, the blocking portion 31a of the stopper 31 is preferably an arc surface centered on the support shaft portion 28. When the engaging projection 22 exerts an acting force on the blocking portion 31a, the acting force is surely applied to the support shaft portion 28. Therefore, the actuating member 26 is not rotated, and illegal acts are surely prevented.

  As described above, the variable winning device 13 according to the present embodiment engages the stopper 31 that prevents the rotation of the engagement protrusion 22 provided on the door member 17 with the transmission means that transmits the driving force of the electric drive source. Since it is provided in the joint portion 30, even if the electrical drive source is not driven and the door member 17 is to be opened, the engagement protrusion 22 stops against the stopper 31 and prevents the door member 17 from rotating in the opening direction. Is done. When the electric drive source is driven, the rotation of the stopper 31 is released and the door member 17 is opened. That is, the door member 17 is movable only when the electric drive source is driven, and is opened by the operating force of the operation member 26.

  As described above, the variable winning device 13 according to the present embodiment can cope with the existing operating member 26 by making only a slight design change, so that the normal operation of the variable winning device 13 can be ensured with a simple configuration. Actions can be prevented. By forming the engaging portion 30 that engages with the engaging protrusion 22 with the gap C2, the stopper 31 can be retracted from the displacement path of the engaging protrusion 22, and the rotation of the door member 17 can be started. Since a time difference can be generated, the configuration of the variable winning device 13 can be simplified, contributing to weight reduction and compactness of the device. In addition, it is not necessary to create a new mold for preventing fraud and the cost can be reduced.

  In the embodiment, the operation portion is the cylindrical shaft-shaped engagement protrusion 22, but a planar portion that can come into surface contact with the blocking portion 31 a of the stopper 31 may be formed on the engagement protrusion 22. When the electrical drive source is not driven, in the state where the planar portion of the engagement protrusion 22 is in surface contact with the blocking portion 31a of the stopper 31, the acting force due to the pressing of the engagement protrusion 22 is the moving direction of the operating member 26. Therefore, the actuating member 26 is not erroneously operated and the locking effect is ensured. The planar portion is not necessarily limited to a flat surface, and may be a gentle arc surface. For example, the blocking portion 31 a of the stopper 31 and the planar portion of the engaging protrusion 22 may be arcuate surfaces centering on the support shaft portion 28 of the operating member 26. Further, a locking portion can be similarly obtained by forming a planar portion on the engaging projection 22 and making the blocking portion 31a of the stopper 31 into an arc shape or the like that can be in line contact or point contact with the planar portion of the engaging projection 22. be able to.

  Further, in the above embodiment, the linkage between the connecting member 25 and the operating member 26 is movable by the linkage between the connecting pin 27 and the operating groove 29, but it is formed on the lower surface of the connecting member 25 as shown in FIG. You may make it link by the meshing | engagement of the gear 27a and the gear 29a formed in the surrounding surface of the action | operation member 26. FIG. The driving force of the solenoid 19 can be reliably transmitted to the door member 17 by making the linkage between the connecting member 25 and the actuating member 26 mesh with the gears 27a and 29a. In this embodiment as well, as in the previous embodiment, when the door member 17 is displaced from the solid line position in the figure to the chain line position or from the chain line position to the solid line position, the engagement protrusion 22 is moved to a predetermined position (for example, the rotation shaft 21). When the height position is reached, it is biased in the direction of the solid line (closed direction) or biased in the direction of the chain line position (opening direction) depending on the position of the center of gravity.

  Further, as shown in FIG. 7, without providing the connecting member 25 as a transmission means, the plunger 24 itself is formed with a linkage portion 36 by a flange as a linkage portion, and an operating pin 37 as an operating portion is protruded from the operating member 26. The actuating pin 37 is directly accommodated and held in the linking part 36 so that the plunger 24 and the actuating member 26 are linked to be able to move together, and the driving force of the solenoid 19 is transmitted to the door member 17 via the actuating member 26. May be. By doing so, the number of parts can be reduced and the cost can be reduced. Further, although the engaging portion 30 is formed in a U-shape when viewed from the side, the engaging portion 30 is formed as a locking hole having a predetermined gap, and a stopper 31 is provided in the gap of the locking hole. Good.

  In the embodiment, the solenoid 19 is provided in a horizontal shape orthogonal to the base plate 15. However, the solenoid 19 may be provided in a horizontal shape so as to be parallel to the base plate 15 so that the plunger 24 advances and retreats in the horizontal direction. Good. Further, when the solenoid 19 is parallel to the base plate 15 and the variable winning device 13 is mounted on the game board 4, the plunger 24 may be provided so as to advance and retreat in the vertical direction. For example, as shown in FIG. As described above, the actuating member 26 linked to the door member 17 is provided on the plunger 24 as a transmission means, and the engaging member 30 is provided on the actuating member 26 to engage with the engaging protrusion 22 of the door member 17. The door member 17 may be opened and closed between the solid line position and the chain line position by the movement. The engaging portion 30 is formed in a U-shape in a side view with the tip substantially the same surface as in the above embodiment, and a stopper 31 as a locking means is engaged in the engaging portion 30 when the solenoid 19 is not driven. A position where the rotation of 22 is prevented, that is, on the rotation orbit of the engagement protrusion 22 is formed in a step shape. The stopper 31 is notched below the substantially vertical blocking portion 31a so that the engaging protrusion 22 does not interfere with the blocking portion 31a during the backward movement. In this embodiment, a flat surface is formed on the engaging protrusion 22 so as to be in surface contact with the blocking portion 31a of the stopper 31. The frame 18 to which the solenoid 19 is attached is provided with a regulating rib 33a as a regulating means for preventing the actuating member 26 from moving backward (leftward in FIG. 8), and the rear wall of the storage portion 18b of the frame 18 is further provided. A restricting projection 33b that makes point contact with the operating member 26 is provided. Accordingly, even if the door member 17 is operated to be opened by an improper external force and the engagement protrusion 22 presses the stopper 31, the operation member 26 is pressed by the engagement protrusion 22 by the restriction rib 33 a and the restriction protrusion 33 b (on the drawing). Since the movement in the lateral direction is restricted, the engagement protrusion 22 cannot rotate and the door member 17 cannot be opened. The restriction ribs 33a and the restriction protrusions 33b also serve as guide portions that allow the operating member 26 to move smoothly up and down when the solenoid 19 is driven.

  In the embodiment, the engagement protrusion 22 is provided on the flange 20 of the door member 17 and the engagement portion 30 having the gap C2 is provided on the operation member 26. However, the engagement protrusion 22 is provided on the operation member 26, A hook-like engagement portion 30 having a gap C2 and a stopper 31 may be provided on the hook piece 20, and the same function and effect can be achieved.

  FIG. 9 shows another embodiment of the locking means, and the same components as those in the above embodiment will be described with the same reference numerals. In this embodiment, the movement of the door member 17 is not directly locked, but a locking means is provided in the connecting portion 38 linked to the connecting member 25 and the operating member 26 to indirectly lock the movement of the door member 17. ing. The locking means of this embodiment prevents rotation of the door member 17 by restricting the movement of the operating pin 37 as an operating portion provided in the operating member 26 in parallel with the rotation shaft 21 of the door member 17. I have to. Specifically, as shown in FIG. 9 (a), an inverted U-shape that can be loosely inserted into the distal end portion of the interlocking piece 25b with a gap C2 that advances and retreats by a predetermined stroke alone with respect to the operating pin 37. A stopper 31 having a blocking portion 31a having a predetermined width on the lower surface is provided as a locking means that prevents the rotation of the operating pin 37 of the operating member 26 when the solenoid 19 is not driven. It is located on the rotating track and swells in the gap C1. The width of the gap C1 of the connecting portion 38 is set so as to have a predetermined gap C2 between the operating pin 37 and the inner surface of the one side when the operating pin 37 is loosely inserted into the connecting portion 38. By advancing and retracting only the stroke of C2, the operating pin 37 is released from the stopper 31 so that the operating member 26 can rotate. Note that the downward rotation range of the operating member 26 is restricted by a restriction member (not shown). Further, the side surface (the right side in the figure) of the stopper 31 facing the backward movement direction is formed as an inclined surface that is inclined toward the lower left, and the operating member 26 is pressed by the inclined surface in the rotating direction. Easy to return. 33c is a guide part which regulates the advancing / retreating direction of the connecting member 25, and this guide part 33c is formed by extending a metal heat dissipating plate which is in contact with the solenoid 21 and fixed by screws or the like. By providing the guide portion 33c, the heat radiating surface is increased, so that the heat radiating efficiency can be improved.

  Next, the operation of the variable winning device 13 having the above configuration will be described. In the normal state in which the solenoid 19 is demagnetized, the connecting member 25 is in the advanced position by the bias of the spring 23 as shown in FIG. 9 (a), and the operating member 26 is rotated downward by its own weight and the engaging portion 30 is engaged. The door member 17 is held in an upright state by pushing down the mating protrusion 22, and the stopper 31 is positioned close to the upper position on the rotation track of the operating pin 37. At this time, the rotational movement of the operating pin 37 is blocked by the blocking portion 31a of the stopper 31, so that unnecessary rotational movement of the door member 17 is blocked, and the door member 17 holds the standing state and does not accept the game ball. Closed.

  When the solenoid 19 is energized, the plunger 24 is retracted against the bias of the spring 23, and as a result, when the connecting member 25 is retracted to a predetermined position as shown in FIG. The movement pin 37 moves away from the rotational track of the operation pin 37 and the rotation prevention of the operation pin 37 is released. When the operating pin 37 is released from the rotation prevention of the stopper 31, the pressing surface of the connecting portion 38 comes into contact with and engages with the operating pin 37 and pulls the operating pin 37, as shown in FIG. Thus, when the operating pin 37 is rotated, the operating member 26 is rotated upward about the support shaft portion 28, and the engaging portion 30 abuts on and engages with the engaging protrusion 22. As the door member 17 is pushed up, the door member 17 is rotated in the opening direction about the rotation shaft 21 by its own weight, so that the game ball is easily opened by winning. At this time, the operating pin 37 is located on the side of the stopper 31.

  Thereafter, when the solenoid 19 is demagnetized and the operation is released, the plunger 24 moves forward by the bias of the spring 23, and at the same time, the operating pin 37 is pushed on the side surface of the stopper 31 to rotate the operating member 26 downward. As shown in FIG. 9 (a), it stands up and enters a closed state.

  On the other hand, in the normal state in which the solenoid 19 is not excited as shown in FIG. 9 (a), the door member 17 is forcibly opened by hooking an unauthorized tool such as a piano wire or a cell plate on the upper end of the door member 17 for an unauthorized purpose. When the forcible operating force is applied, the engaging protrusion 22 tries to rotate the operating member 26 via the engaging portion 30, but the operating pin 37 contacts the blocking portion 31 a of the stopper 31 and rotates. Is prevented and the locking effect is maintained. For this reason, the door member 17 is not opened, and it is possible to reliably prevent an illegal act of unjustly winning a winning ball. Even when the operation pin 37 presses the stopper 31 when the door member 17 is operated to be opened by an improper external force, the connecting member 25 is moved in the pressing direction (upward in the figure) by the guide portion 33c. Is restricted, and the rotation of the operating pin 37 is reliably prevented.

  As described above, the connecting member 25 for transmitting the driving force of the electric driving source and the stopper 31 for preventing the movement of the door member 17 are provided on the connecting portion 38 of the actuating member 26, and the electric driving source is not driven. When an external force in the opening direction is applied to the door member 17 in such a state, the operating pin 37 can stop against the stopper 31 and can be provided with a locking means that prevents the door member 17 from rotating.

  In the above embodiment, the door member 17 and the transmission means are linked by the engagement of the engagement portion 30 and the engagement protrusion 22, but as shown in FIG. The gear 22a formed on the surface and the gear 30a formed on the peripheral surface of the operating member 26 may be linked to each other.

  In this embodiment, the points different from the above embodiment are the linking means of the actuating member 26 and the door member 17 and the driving direction of the solenoid 19, and the other same components will be described with the same reference numerals. In this embodiment, the solenoid 19 is provided so as to be substantially orthogonal to the door member 17, and the plunger 24 is advanced by excitation of the solenoid 19. Therefore, the connecting portion 38 is formed in a U shape having a predetermined gap C1, and the stopper 31 that can prevent the operating pin 37 of the operating member 26 from rotating is on the rotation track of the operating pin 37 and It is provided on the door member 17 side. The center of gravity of the actuating member 26 is preferably set so that the actuating member 26 is normally urged in the right rotation direction in the figure. For example, when the solenoid 19 is demagnetized by providing a weight for returning the actuating member 26, the plunger of the solenoid 19 is provided. 24 is returned by the urging force of the spring 23, and the operating member 26 is also reliably returned to its original position by the force pulled by the connecting member 25 and the assisting force of the weight itself. For this reason, the spring 23 can have a weak biasing force, which can contribute to cost reduction.

  In the variable winning device 13 of this embodiment, the operation pin 37 is positioned above the upper blocking portion 31a of the stopper 31 in a normal state where the solenoid 19 is demagnetized as shown in FIG. When the solenoid 19 is energized, the plunger 24 moves forward against the bias of the spring 23, and as a result, the connecting member 25 moves forward to a predetermined position as shown in FIG. When it moves away from the pin 37 by the distance of the gap C2 and departs from the rotation track of the operating pin 37, the rotation prevention of the operating pin 37 is released. When the operating pin 37 is released from the rotation prevention of the stopper 31, the rear pressing surface of the connecting portion 38 comes into contact with and engages with the operating pin 37 to push the operating pin 37 forward, as shown in FIG. As shown in FIG. 4, the operating pin 37 rotates to rotate backward about the support shaft portion 28, and the door member 17 is engaged with the gear 30 a of the operating member 26 and the gear 22 a of the door member 17. Is rotated in the opening direction around the rotation shaft 21, and the game ball is in a fully open state where it is easy to win. At this time, the operating pin 37 is located on the side of the stopper 31.

  Thereafter, when the solenoid 19 is demagnetized and the operation is released, the plunger 24 is retracted by the bias of the spring 23 and at the same time, the operating pin 37 is pushed on the side surface of the stopper 31 to rotate the operating member 26 forward. As shown in FIG.

  On the other hand, in the normal state in which the solenoid 19 is not excited as shown in FIG. 10 (a), the door member 17 is forcibly opened by hooking an unauthorized tool such as a piano wire or a cell plate on the upper end of the door member 17 for an unauthorized purpose. When the forcible operating force is applied, the actuating member 26 tries to rotate by meshing the gears 22a and 30a, but the actuating pin 37 abuts against the blocking portion 31a of the stopper 31 to prevent the rotation and the locking effect. Is preserved. At this time, since the connecting member 25 is not bent or moved in the pressing direction of the operating pin 37 by the guide portion 33c, an illegal act can be surely prevented.

  Further, although the electrical drive source is the solenoid 19, a forward / reverse motor or a rotary solenoid may be used. When the electrical drive source is a forward / reverse motor or a rotary solenoid, for example, the drive shaft of the electrical drive source is fixed to the shaft support portion of the operating member 26 shown in the above embodiment, and the drive source is rotated forward and backward. Thus, the operating member 26 can be swung to open and close the door member 17. It is also possible to provide an eccentric cam for the forward / reverse motor and the rotary solenoid, and to link the eccentric cam to the eccentric position of the operating member 26 to swing the operating member 26.
