Description

  The present invention relates to a game medium payout apparatus and the like provided with a game surface on which a game medium is placed and drive means for reciprocatingly sliding a game medium extrusion unit along the game surface.

  There is an amusement device called a pusher-type prize payout game machine. A pusher-type prize payout game machine is a part called a “pusher” that reciprocates and slides along a play surface. A push medium placed on the play surface is pushed down and dropped from a payout outlet, and several play media are dropped. A device that pays out to a player.

  Typical forms include, for example, an excavator that scoops up a prize placed on a rotating turntable, a fixed table corresponding to a play surface, and a pusher that moves on the fixed table so as to approach or move away from the prize payout exit. The thing provided with the slide table corresponded to is known.

  When the player inputs a start instruction, the excavator automatically picks up the prize from the turntable, and when the player inputs a drop instruction, the excavator drops the scooped up prize on the fixed table. The prizes dropped on the upper surface of the fixed table are sequentially pushed by the slide table and eventually fall from the fixed table. The player can acquire a prize if the dropped prize successfully enters the prize payout exit. Such pusher-type prize payout game machines are particularly popular among women and children as games that are easy to understand and enjoy for everyone. Of course, in addition to prizes such as confectionery and toys, coins and medals can be used as play media.

[First Embodiment]
FIG. 1 is a diagram showing an example of the appearance of a game apparatus 1000 to which the present invention is applied. The game apparatus 1000 is a so-called “pusher game machine” or “pusher-type prize payout game machine”.

  As shown in the figure, the game apparatus 1000 includes (1) a turntable 1002 on which a plurality of prizes P are placed and stored, and (2) an excavator apparatus 1004 that scoops up the prize P placed on the turntable 1002. (3) A fixed table 110 on which the scooped up prize P is unloaded from the excavator device 1004 and placed thereon, and (4) a slide table 120 that reciprocally slides along the fixed table 110 so as to approach or move away from the prize outlet 1008. And (5) a control unit 1020 having an operation panel 1014 of the shovel device 1004, and (6) an arithmetic processing device such as a CPU or LSI, an IC memory 1024, an electric circuit, and the like, and comprehensively controlling the operation of the game device 1000. And (7) a power supply unit (not shown). In order to prevent the prize P from being interfered from the outside, these are covered and protected by a transparent cover 1017. The game apparatus 1000 is installed such that the turntable 1002 is substantially horizontal.

  The play device 1000 in this embodiment includes a shovel device 1004, a fixed table 110, a slide table 120, an operation panel 1014, and a prize payout outlet 1008 as a set, and has a total of four play positions in a substantially cross shape when viewed from above.

  The control unit 1020 includes an arithmetic processing device such as a CPU and LSI, an IC memory 1024, and the like, and controls the operation of the game device in an integrated manner in accordance with a program stored in the IC memory 1024.

  The turntable 1002 is formed with an annular groove that opens upward, and a large number of prizes P can be placed on the bottom upper surface of the groove portion. And it rotates slowly on the predetermined plane by the drive of the motor for turntables (not shown) centering on the rotating shaft A provided in the center of the game apparatus 1000. Since the game apparatus 1000 is installed so that the turntable 1002 is substantially horizontal, the rotation axis A is a substantially vertical axis.

  The cover 1017 is a transparent cover that is formed of a transparent resin or the like and can be seen inside. A detachable supply lid 1017a is provided on the upper portion of the cover 1017, and the prize P can be replenished to the turntable 1002 by opening the supply lid 1017a.

  The fixed table 110 is a substantially horizontal flat plate extending from the center of the apparatus toward the outer edge of the apparatus above the turn table 1002. The outer edge side end of the fixed table 110 is configured to reach above the prize payout exit 1008.

  The slide table 120 is a flat plate that reciprocates along the upper surface of the fixed table 110 so as to approach or move away from the prize outlet 1008, and corresponds to a so-called “pusher”.

  The shovel device 1004 rotates the arm 1004a by the motor 1004c in response to an operation input from the operation panel 1014, scoops up the prize P arranged on the turntable 1002 by the shovel 1004b, and drops it on the fixed table 110.

  Then, the prize P ′ dropped on the fixed table 110 by the shovel device 1004 is sequentially pushed in the direction of the prize payout exit 1008 by the reciprocating sliding motion of the slide table 120. Eventually, when the prize P ′ is pushed to the end of the fixed table 110 and falls to the prize payout outlet 1008, the player can take out the prize P ′ from the prize takeout outlet 1018 communicating with the prize payout outlet 1008.

  That is, the upper surface of the fixed table 110 corresponds to a game surface, and the fixed table 110, the slide table 120, and the drive unit of the slide table 120 correspond to a game medium dispensing device that pays out game media. In the figure, the drive unit of the slide table 120 is provided in the center cowl 1011 and is invisible to the player.

  In the following, based on the extending direction of the fixed table 110, the direction of the prize payout outlet 1008 is “front”, the direction away from the prize payout outlet 1008 (center direction of the apparatus) is “back”, and from the front-back direction. The direction that forms a right angle substantially horizontally is referred to as “right” and “left” with reference to the center line of the fixed table 110. Further, the operation of pushing the slide table 120 in the direction of the prize payout outlet 1008 is “return” “out”, and the operation of pushing the slide table 120 back is “return”.

[Description of game media payout device]
FIG. 2A is a perspective view showing an example of the configuration of the game medium dispensing apparatus 100 in the present embodiment, and FIG. 2B is a vertical sectional view along a fixed table. As shown in the figure, the game medium payout device 100 includes a fixed table 110, a slide table 120, and a slide table drive unit 140. The slide table drive unit 140 is housed in the center cowl 1011. From the outside, only the fixed table 110 and the slide table 120 appear to extend from the center cowl 1011 toward the prize payout outlet 1008.

  The fixed table 110 is a plate-like member having a sandwich structure in which a structural plate 114 is sandwiched between an upper plate 112 and a lower plate 116. The upper surface of the upper plate 112 corresponds to the play surface, and the slide table 120 slides on the upper surface. The end of the lower plate 116 reaches the center of the game apparatus 1000 and is fixed to the game apparatus 1000. The structural plate 114 is a main structure that forms the thickness of the fixed table 110. Since the length is shorter than that of the upper plate 112 and the lower plate 116, a space for accommodating a part of the slide table driving unit 140 is formed between the upper plate 112 and the lower plate 116 on the center side of the apparatus.

  The slide table 120 includes a table plate 122 and a pair of guide plates 124. The table plate 122 is a member that pushes the prize P 'on the fixed table 110, and forms a box having an open lower surface and a rear surface. The space inside the table plate 122 acts as a space for preventing interference with a slide table drive unit 140 described later.

  The guide plate 124 is a plate member that is fixed to the left and right end surfaces of the table plate 122 so as to extend downward. The lower end of the guide plate 124 contacts the left and right end surfaces of the fixed table 110, and the slide table 120 is fixed to the fixed table. Acts as a guide for sliding along 110.

  The slide table drive unit 140 is slidable in a main motor 142 having a vertically upward rotation axis A as an output shaft, a crank arm 144 extending perpendicularly from the output shaft of the main motor 142, and a direction in which the crank arm 144 extends. The connecting rod connecting portion 146 has a connecting rod 148 that has one end rotatably connected to the upper portion of the connecting rod connecting portion 146 and a vertical axis B. The other end of the connecting rod 148 is rotatably connected to the slide table 120 with a vertical axis C. A roller 150 that is rotatable about the vertical axis B is provided at the lower end of the connecting rod connecting portion 146, and is urged by the compression coil spring 152 together with the connecting rod connecting portion 146 in the outer peripheral direction of the crank.

  The slide table drive unit 140 has an inscribed surface (contact surface) F surrounding the crankshaft, and the roller 150 is urged together with the connecting rod connecting portion 146 by the compression coil spring 152 in the outer peripheral direction of the crank. Abuts F.

  That is, the slide table drive unit 140 forms a reciprocating slider-crank mechanism in which the output shaft of the main motor 142 is a crankshaft, the distance from the axis A to the axis B is a crank radius, and the slide table 120 is a slider. . When the main motor 142 rotates, the roller 150 moves along the inscribed surface F. Therefore, the crank radius of the slide table drive unit 140 varies based on the shape of the inscribed surface F.

  FIG. 3 is a partial perspective view of the slide table driving unit 140 in the present embodiment, and shows an example of the configuration of the inscribed surface F. In the figure, a part of the fixed table 110 and the slide table 120 are omitted.

  As shown in the figure, the inscribed surface F of the slide table driving unit 140 is a pair of opposing concave semicircles Fa and Fb and ends of the concave semicircle when viewed from above (when viewed from above). A parallel ellipse formed from two parallel straight lines Fc and Fd connecting the portions is formed. The long axis faces the reciprocating slide movement direction of the slide table 120.

  The inscribed surface F includes a concave semicircle member 154 having a concave semicircle Fb on the reverse side (rear side with respect to the crankshaft) as an end surface, and a concave semicircle on the forward side (front side with respect to the crankshaft). A U-shaped member 156 that forms a U-shape in a top view is formed by facing Fa and the two straight lines Fc and Fd.

  The concave semicircular member 154 is fixed to the rear end portion of the lower plate 116 of the fixed table 110. The U-shaped member 156 is disposed in a space between the upper plate 112 and the lower plate 116 of the fixed table 110 so as to be slidable in the reciprocating sliding direction (front-rear direction) on the lower plate 116.

  The U-shaped member 156 is provided with a rack 158 in the reciprocating slide direction (front-rear direction), and meshes with the sub motor 160 fixed to the game apparatus 1000 via a pinion gear 162 provided on the rotation shaft of the sub motor 160. ing.

  The sub motor 160 is a shaft rotation type motor capable of detecting a rotation angle, and the rotation is controlled by the control unit 1020. When the sub motor 160 rotates, the U-shaped member 156 is slid in the front-rear direction by the rack-and-pinion mechanism. The concave semicircular member 154 is configured such that the left and right end surfaces thereof are in contact with the two straight lines Fc and Fd of the U-shaped member 156, so that the ellipse of the inscribed surface F has a variable long diameter as the U-shaped member 156 slides. In this way, the shape is changed.

  Therefore, by controlling the rotation of the sub motor 160, the horizontal cross-sectional shape of the inscribed surface F is changed, and by changing the shape of the inscribed surface F, the moving path of the roller 150 is changed to change the crank radius. be able to.

  FIG. 4 is a diagram illustrating an example of a deformed state of the inscribed surface F in the present embodiment. FIG. 6A shows a state in which the pinion gear 162 is driven clockwise and the U-shaped member 156 is moved backward to the full width of the rack 158. In this state, the concave semicircle Fb of the concave semicircular member 154 and the concave semicircle Fa of the U-shaped member 156 are in direct contact at both ends of the diameter, and the inscribed surface F has a circular horizontal cross section. The rotation axis of the main motor 142 coincides with the center of the circle formed by the inscribed surface F, and the crank radius of the slide table driving unit 140 is constant. Therefore, when the main motor 142 is rotated, the slide table 120 performs a periodic reciprocating motion in which the push-out operation and the pull-back operation take equal time. In this case, the extrusion amount of the slide table 120 is minimized.

  FIG. 5B shows a state in which the pinion gear 162 is driven counterclockwise from the state of FIG. 5A and the U-shaped member 156 is moved forward to the full width of the rack 158. In this state, the concave semicircle Fb of the concave semicircular member 154 and the concave semicircle Fa of the U-shaped member 156 are in the most separated state.

  When the pinion gear 162 is driven counterclockwise from the state shown in FIG. 9A, the ellipse of the inscribed surface F has the position of the rear end on the long diameter side (that is, the concave semicircle Fb on the reverse side). While the pinion gear 162 is rotated, the front end of the long diameter (that is, the forward concave semicircle Fa) is separated with the rotation of the pinion gear 162, and both ends of the diameter of the concave semicircle Fb are concave half via the two straight lines Fc and Fd. It becomes a parallel ellipse connected to the end of the circle Fa. As the pinion gear 162 is driven counterclockwise, the lengths of the two straight lines Fc and Fd increase, and the state shown in FIG. In this case, the position of the rotation axis A of the main motor 142 is also fixed with respect to the fixed table 110.

  Therefore, when the main motor 142 is rotated in a state where the horizontal section of the inscribed surface F is an ellipse instead of a circle, the slide table drive unit 140 has a crank radius on the forward movement side (front side with respect to the crankshaft). It is larger than the crank radius (rear side with respect to the crankshaft). In the state shown in FIG. 5B, the amount of slide table 120 is maximized.

  With the above configuration, it is possible to freely vary the movement amount (extrusion amount) during forward movement without changing the movement amount during backward movement of the slide table 120 with a simple structure. Further, since the connecting rod connecting portion 146 is biased by the compression coil spring 152, for example, even if the prize P ′ on the fixed table 110 cannot be moved further in the direction of the prize payout outlet 1008 for some reason, the slide table 120 is The force of pushing the prize P ′ is absorbed by the compression coil spring 152 being contracted, and an effect of preventing the prize P ′ from being damaged due to excessive force is also obtained.

[Explanation of operation flow]
FIG. 5 is a flowchart for explaining the flow of operation control of the slide table driving unit 140 in the present embodiment. The series of processing described here is realized by executing a predetermined program stored in the IC memory 1024 of the control unit 1020, for example.

  In the game apparatus 1000, the turntable 1002 is always rotated when the power is turned on, and the main motor 142 is in a driving state so that the slide table 120 always performs reciprocating sliding movement. When the player inputs an operation of the shovel device 1004 from the operation panel 1014, the game starts.

  As shown in the figure, when the game is started, first, the control unit 1020 minimizes the pushing amount of the slide table 120 (step S2). Specifically, the sub motor 160 is rotated clockwise to a predetermined angle, and the U-shaped member 156 is moved backward to the full width of the rack 158.

  Next, the control unit 1020 generates a random number (step S4), and determines whether the random number satisfies a predetermined bonus condition (step S6).

  When it is determined that the random number satisfies the bonus condition (step S6; YES), the control unit 1020 rotates the sub motor 160 by a predetermined amount in the counterclockwise direction, and the amount of extrusion of the slide table 120 is medium (same as in FIG. 4A). (B) an intermediate state) (step S8). Then, the timer counts a predetermined time enough for the slide table 120 to reciprocate several times (step S10). Therefore, the extrusion amount of the slide table 120 increases at random timing, and this state continues for a predetermined time.

  Next, after a predetermined time has elapsed, the control unit 1020 generates a random number again (step S12), and determines whether the random number satisfies a predetermined bonus condition (step S14). If it is determined that the bonus condition is satisfied (step S14; YES), the control unit 1020 further rotates the sub motor 160 in the counterclockwise direction to maximize the pushing amount of the slide table 120 (step S16). Then, the timer is counted for a predetermined time such that the slide table 120 reciprocates once (step S18).

  Therefore, the slide table 120 slides with the maximum amount of extrusion only once at random timing, and if the prize P ′ can be placed on the fixed table 110 so far, a larger quantity of prize than usual. P ′ can be pushed down to the prize payout exit 1008. Lucky for the player.

  Next, the control unit 1020 determines a game end condition (step S20). For example, if the elapsed time from the start of the game or the number of operations of the excavator device 1004 reaches a specified value, it is determined that the end condition is satisfied.

  If the end condition is not satisfied (step S20; NO), the process returns to step S2, and the control unit 1020 once returns the pushing amount of the slide table 120 to the minimum state and continues the game. On the other hand, if the end condition is satisfied (step S20; YES), the game is over.

  With the above processing, it is possible to control the timing at which the crank radius is varied and to realize a prize payout game in which the amount of extrusion of the slide table 120 is varied at random timing.

[Second Embodiment]
Next, as a second embodiment of the present invention, an example of a different configuration for deforming the cross-sectional shape of the inscribed surface F will be described. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and description shall be abbreviate | omitted suitably.

  FIG. 6 is a perspective view showing an example of the configuration of the game medium payout device 100-2 in the present embodiment. As shown in the figure, the slide table driving unit 140-2 in the present embodiment has an elastic ring 170 disposed on the upper surface of the fixed table 110 so as to be centered on the rotation axis A of the main motor 142, and a clamp 176. It is pinched. In the present embodiment, the inner surface of the elastic ring 170 corresponds to the inscribed surface F and contacts the roller 150.

  The elastic ring 170 is a ring member having a substantially equal width made of, for example, an elastic resin or a leaf spring material, and has a property of elastically deforming by an external force but returning to an annular shape in a natural state. The elastic ring 170 is disposed so that the center of the ring coincides with the rotation axis A of the main motor 142, and the rear end thereof is fixed to a stopper 172 fixed to the upper surface of the rear portion of the fixed table 110. Further, the left and right sides are clamped by a pair of clamps 176 driven by an extrusion cylinder 174.

  The extrusion cylinder 174 is a cylinder that is pushed and pulled by electric power, compressed air, hydraulic pressure, etc., and is controlled by the control unit 1020 so as to perform the same operation on both the left and right sides. The clamp 176 is slidably engaged with a guide groove 178 linearly provided in the left-right direction on the upper surface of the fixed table 110, and holds the elastic ring 170 while maintaining a substantially parallel state in the front-rear direction.

  FIG. 7 is a diagram illustrating an example of a deformed state of the inscribed surface F in the present embodiment. FIG. 6A shows a state where the extrusion cylinder 174 is not pushed, and no external force is applied to the elastic ring 170. Therefore, the elastic ring 170 has an annular shape. Since the rotation shaft of the main motor 142 coincides with the center of the circle formed by the inscribed surface F, the crank radius of the slide table driving unit 140 is constant. Therefore, when the main motor 142 is rotated, the slide table 120 performs a periodic reciprocating motion in which the push-out operation and the pull-back operation take equal time. In this case, the extrusion amount of the slide table 120 is minimized.

  FIG. 6B shows a state where the extrusion cylinder 174 is pushed out most. When the extrusion cylinder 174 is pushed out, the elastic ring 170 receives a force compressing from the left and right by the clamp 176. Since the rear end of the elastic ring 170 is fixed to the stopper 172, the elastic ring 170 is deformed from an annular shape to an ellipse so as to be crushed forward. That is, the cross-sectional shape of the inscribed surface F is deformed. In the state shown in FIG. 5B, the amount of slide table 120 is maximized.

  With the above configuration, it is possible to freely vary the movement amount (extrusion amount) during forward movement without changing the movement amount during backward movement of the slide table 120 with a simple structure.

[Description of Modification]
As described above, the first to second embodiments to which the present invention is applied have been described. However, the present invention is not limited to these embodiments, and as long as the same operations and effects are obtained, the addition, omission, and combined use of the components are appropriately performed.・ Changes may be made.

  For example, although the U-shaped member 156 is moved by the rack and the pinion gear, it may be realized by switching a plurality of linear motion motors provided so as to be movable back and forth or cams having different lift amounts.

  In the above-described embodiment, the contact surface with which the roller 150 contacts is the inscribed surface F, but may be configured to contact with the outer surface. Further, instead of the inscribed surface F and the roller 150, a guide rail and a slider that moves along the guide rail may be used.

  Further, the slide table 120 and the slide table driving unit 140 are not limited to a single one, and a plurality of these may be provided as a set.

  Further, although the bonus condition is determined by generating a random number as time passes, the present invention is not limited to this. For example, a so-called roulette method may be employed in which a sensor is provided at a limited position at the end of the fixed product 110 on the side of the prize payout outlet 1008, the fall of the prize P ′ is detected by the sensor, and a random number is generated when the fall is detected. Of course.
