Description

  The present invention relates to a claim game machine that transports a catcher portion provided with a mechanism for holding a prize by a rail.

Generally, in a crane game machine, a player hangs a catcher portion provided with a mechanism for holding a prize on a catcher rail provided near the ceiling of the housing, and transports the rail according to an instruction from the player, thereby allowing the player to It can be moved to the required position. In a circular crane game machine in which the outer shape of the casing is circular, the catcher rail can be turned horizontally so as to draw an arcuate locus with one end of the catcher rail as a base point. Then, by moving the catcher portion in the radial direction on the catcher rail, it is possible to reach the position requested by the player. Generally, in a circular claim game machine, a pillar for supporting the casing structure at the center of the casing. Is provided. For this reason, the base point for turning the catcher rail in the horizontal direction is provided at a position slightly shifted outward so as to avoid the pillar. As a result, the distance from the center of the housing to the outer peripheral surface and the distance from the base point of the catcher rail to the end of the rail are different, and the catcher portion moves along an arc-shaped trajectory parallel to the outer peripheral surface of the housing. I can't let you. That is, the movement range of the catcher part is limited, and even if a prize stand is provided in the entire housing so that a prize can be placed, a range where the catcher part does not reach occurs.

  For such a limitation on the range of motion of the crane, a prize-grabbing game machine has been considered in which the dead angle range of the crane mechanism is eliminated and appropriate motion is performed in the game space (see Patent Document 1).

In the prize-grabbing game machine described in Patent Document 1, an inner curved guide rail and an outer curved guide rail are provided, and a radial guide rail for moving the crane mechanism in the radial direction is disposed between the two rails. The direction guide rail is configured to move in the circumferential direction. As a result, the dead angle range of the crane mechanism is eliminated by the combined motion by the turning motion of the radial guide rail in the horizontal plane and the radial motion by the radial guide rail.
Japanese Utility Model Publication No. 5-29584

  In the conventional prize-grabbing game machine described in Patent Document 1, an inner curved guide rail and an outer curved guide rail are provided, and the radial guide rail is moved in the circumferential direction by the two rails. . Therefore, at both ends of the radial guide rail, a mechanism for transporting the inner curved guide rail and the outer curved guide rail having different radii at different pitches so as not to deviate from the common axis is required. That is, a complicated mechanism with high accuracy is required, and the possibility of failure increases due to the influence of variations in manufacturing.

  In addition, in the conventional prize-grabbing game machine, when the reach of the catcher part is widened even by a slight design change, the interval between the inner curved guide rail and the outer curved guide rail is widened, and accordingly Since the radial guide rail had to be constructed in a new size, it could not be flexibly accommodated.

  The present invention has been made in consideration of the above-described circumstances, and the object thereof is to enable the catcher rail to be transported to a range along the outer periphery of the casing in a configuration in which the catcher rail is turned in the horizontal direction, and manufacturing variations. Another object of the present invention is to provide a crane game machine that can cope with changes in design and design.

  The present invention provides a catcher portion provided with a mechanism for gripping a prize, a catcher rail for hanging the catcher portion and transporting it horizontally, and a rotation shaft attached to the ceiling of the housing. A rotating shaft mechanism for turning horizontally around the vicinity of one end, a guide rail defining a turning range of the catcher rail attached to the ceiling of the housing, and the other of the catcher rail A drive mechanism that is provided near the end portion and that rotates along the guide rail to turn the catcher rail, and the rotating shaft mechanism portion rotates by the turning of the catcher rail by the drive mechanism. As the distance between the shaft and the position of the drive mechanism of the guide rail changes, the catcher rail Transport mechanism for moving in the longitudinal direction of the serial catcher rail, characterized in that is provided.

  According to the present invention, the catcher rail itself for suspending the catcher unit and transporting it in the horizontal direction is provided with a transport mechanism for moving the catcher rail in the longitudinal direction of the catcher rail. Even if the distance between the rotating shaft for turning the rail and the driving mechanism for moving the guide rail changes, the catcher rail can be slid to follow the guide rail. For this reason, by arranging the guide rail along the outer periphery of the housing, the catcher portion can reach a range along the outer periphery of the housing. In addition, because the catcher rail can be moved to follow the guide rail, there may be fluctuations in the location of the guide rail due to manufacturing variations, or design changes within the range in which the catcher rail can be moved. However, it is possible to respond flexibly without changing the design of the entire mechanism.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration of a crane game machine 10 according to the present embodiment. The crane game machine 10 shown in FIG. 1 shows an example in which four terminals provided with a game field having a bottom portion of, for example, a quadrant (a sector having a central angle of 90 °) are connected. In the crane game machine 10 according to the present embodiment, as shown in FIG. 1, the game fields of four terminals may be in a continuous state, or can be divided into compartments by a panel to be described later for each terminal.

  The two terminals may be connected to form a semicircular game field, or a game field having another shape such as a rectangle is formed on the crane game machine 10 on which the semicircular game field is formed. It is also possible to adopt a configuration in which connected terminals (crane game machines) are connected.

  In the crane game machine 10 shown in FIG. 1, the lower housing 12 is provided with a prize outlet 20 for each terminal. The prize takeout port 20 communicates with a prize dropout opening 32 provided in the game field, and a prize dropped at the prize dropout opening 32 can be acquired. On the upper surface of the lower housing 12, a control panel 21 that is operated by a player is provided. The control panel 21 is provided with a joystick 22, a button 23, a coin slot 24, a speaker, and the like. The control panel 21 is provided in each of the four terminals.

  In the upper housing 14, the game field and the outside are separated by a transparent plate 15 such as an acrylic plate. The game field in the transparent plate 15 is provided with a prize floor 30, a catcher unit 31, a prize drop opening 32, and the like.

  In the crane game machine 10 according to the present embodiment, for example, a three-stage prize floor 30 is provided in the game field. Each stage of the prize floor 30 has an upper surface that is similar to the shape of the bottom surface of the game field (quarter-circle (fan shape)).

FIG. 2 is a diagram for explaining the movement range of the catcher unit 31 in one terminal in the present embodiment.
FIG. 2 shows the shape of the horizontal cross section of the housing. As shown in FIG. 2, the shape of the horizontal cross section of the housing in one terminal, that is, the shape of the prize floor 30 and the ceiling provided at the bottom of the game field is a quadrant (fan shape).

  When a round type claim game machine can be configured by combining four terminals, a pillar for supporting the casing structure is usually provided at the center of the casing. For this reason, in each terminal, the catcher rotation axis position 33, which is the base point for turning the catcher rail in the horizontal direction, is slightly set so as to avoid the pillar (the position of the apex that forms the central angle of the fan shape) as shown in FIG. It is provided in the position shifted to.

  When the catcher rotation axis position 33 is deviated from the apex forming the central angle of the sector shape, when one end portion of the catcher rail having a fixed length is turned around the catcher rotation axis position 33 as a base point, a broken line A in FIG. The range shown in FIG. In this case, when the length of the catcher rail is adjusted from the catcher rotation shaft position 33 to the center of the fan-shaped arc, there is a range where the catcher portion 31 does not reach in the vicinity of both ends of the arc.

  In the crane game machine 10 according to the present embodiment, the catcher portion 31 includes not only the center of the arc but also the vicinity of both ends of the arc as shown by the solid line B in FIG. 2 without changing the position of the catcher rotation shaft position 33. Be reachable.

  FIG. 3 shows an outline of a mechanism for transporting the catcher unit 31 provided in the crane game machine 10 in the present embodiment. FIG. 3 is a view of the ceiling from the inside of the housing.

  As shown in FIG. 3, the ceiling of the casing is formed in a quadrant (fan shape), and a circular crane is formed by combining the four terminals so that the apexes forming the central angle of the sector match. A game machine can be configured.

  A catcher rotation axis position 33 is provided in the vicinity of the quadrant (fan-shaped) apex. A rotation shaft mechanism 35 is mounted at the catcher rotation shaft position 33.

  The rotating shaft mechanism 35 is turned in the horizontal direction with the rotating shaft attached to the ceiling of the housing as a base point near one end of the catcher rail. The rotating shaft mechanism unit 35 is provided with a catcher rail 36 for moving the catcher unit 31 in the radial direction so that it can turn in the horizontal direction. A catcher lifting mechanism 37 is mounted on the catcher rail 36 so as to be slidable in the longitudinal direction (radial direction). The catcher raising / lowering mechanism 37 suspends the catcher part 31 and raises / lowers a gripping mechanism including a gripping arm provided at a tip part of the catcher part 31.

  The catcher rail 36 is turned horizontally by the rotating shaft mechanism 35 from the position shown in FIG. 3A to the position shown in FIG. 3C. A drive mechanism 38 is provided near the end of the catcher rail 36. The drive mechanism 38 turns the catcher rail 36 in the horizontal direction by moving in the circumferential direction along the drive mechanism guide rail 39 provided on the ceiling of the housing. The drive mechanism guide rail 39 defines the turning range of the catcher rail, and is provided in close proximity to the outer peripheral portion (transparent plate 15) of the housing. In other words, the drive mechanism guide rail 39 is arranged so that the catcher portion 31 transported by the catcher rail 36 reaches the vicinity of the transparent plate 15 including both ends of the arc. Therefore, as indicated by B in FIG. 2, the distance from the catcher rotation shaft position 33 to the drive mechanism guide rail 39 differs depending on the turning position of the catcher rail 36, and the center of the arc is the shortest, and both ends of the arc are It is the longest.

  In the crane game machine 10 according to the present embodiment, the catcher rail 36 (drive mechanism 38) follows the drive mechanism guide rail 39 according to the position where the drive mechanism 38 turns the catcher rail 36 along the drive mechanism guide rail 39. As described above, the catcher rail 36 is moved in the longitudinal direction by the rotating shaft mechanism 35. That is, since the distance between the catcher rotation shaft position 33 and the drive mechanism guide rail 39 is the longest at both ends of the arc, the catcher rail 36 is moved in the direction of the drive mechanism guide rail 39 at the turning positions shown in FIGS. The distance moved is the longest. Details of the rotating shaft mechanism 35 will be described with reference to FIGS. 5 and 6.

  FIG. 4 is a diagram showing a detailed configuration of the drive mechanism 38. 4A is a top view of the periphery of the drive mechanism 38 viewed from the housing ceiling side, FIG. 4B is a side view, and FIG. 4C is a front view of the drive mechanism guide rail 39 viewed from the inside. FIG. 4D is a front view seen from the outside of the drive mechanism guide rail 39.

  As shown in FIG. 4B, the drive mechanism guide rail 39 has a U-shaped cross section, and the upper side is attached to the ceiling 40 of the housing so that the concave portion faces the catcher rotation shaft position 33 side. It has been.

  The drive mechanism 38 is mounted with various components described below on the drive mechanism base 42. The outer rail clamping roller 50 is pressed against the outer peripheral side of the drive mechanism guide rail 39, and the inner level clamping rollers 51 and 52 are pressed from the inner peripheral side of the drive mechanism guide rail 39. The drive mechanism guide rail 39 is sandwiched between the outer rail clamping roller 50 and the inner level clamping rollers 51, 52, so that the drive mechanism 38 can be stably moved along the drive mechanism guide rail 39. The moving wheel 53 is provided to rotate in the circumferential direction at the upper part of the lower side of the drive mechanism guide rail 39, and supports the drive mechanism 38 on the drive mechanism guide rail 39.

  The drive roller 56 rotates at the upper part of the lower side of the drive mechanism guide rail 39 to move the drive mechanism 38 in the circumferential direction along the drive mechanism guide rail 39. The drive roller 56 is connected to a motor 58 via a motor shaft 57, and the power of the motor 58 is transmitted. The motor shaft 57 is supported by a shaft support member 60 provided on the drive mechanism base 42.

  The roller 61 is provided below the drive mechanism base 42 and supports the drive mechanism 38 on the catcher rail 36.

  The drive mechanism 38 is coupled to the catcher rail 36 via a coupling shaft 65 and a coupling shaft coupling member 67 as shown in FIGS. The connecting shaft 65 allows the catcher rail 36 to rotate in the horizontal direction with respect to the drive mechanism 38. In the drive mechanism 38, the drive mechanism guide rail 39 is clamped by the outer rail clamping roller 50 and the inner level clamping rollers 51 and 52. Therefore, the axis of the motor 58 (motor shaft 57) is substantially perpendicular to the contact surface of the drive mechanism guide rail 39 regardless of the turning position of the catcher rail 36. On the other hand, since the center position of the arc drawn by the drive mechanism guide rail 39 arranged in parallel with the transparent plate 15 and the catcher rotation shaft position 33 for turning the catcher rail 36 are shifted, the longitudinal direction of the catcher rail 36 is shifted. The shaft does not become perpendicular to the contact surface of the drive mechanism guide rail 39 at the turning position off the central portion of the drive mechanism guide rail 39 (position B in FIG. 3). By coupling the drive mechanism 38 and the catcher rail 36 via the connecting shaft 65, a change in the angle of the catcher rail 36 with respect to the drive mechanism guide rail 39 can be allowed.

  As shown in FIG. 4C, the drive roller 56 is in pressure contact with the upper part of the lower side of the drive mechanism guide rail 39, and the drive mechanism 38 is moved to the drive mechanism guide rail 39 as the motor 58 rotates. The catcher rail 36 coupled to the drive mechanism 38 via the connecting shaft 65 is turned in the horizontal direction.

  FIG. 5 is a diagram showing a detailed configuration around the rotating shaft mechanism 35. FIG. 5A is a plan view of a catcher rotating shaft 72 that rotatably attaches the rotating shaft mechanism unit 35 to the ceiling 40 of the housing, and FIG. 5B is a catcher disposed at the lower portion of the rotating shaft mechanism unit 35. FIG. 5C is a partial cross-sectional view of a side surface of the rotary shaft mechanism 35 and the transport mechanism, showing a transport mechanism for transporting the lifting mechanism 37 on the catcher rail 36.

  As shown in FIG. 5A, a rotating shaft holding member 70 is attached to the ceiling 40 of the housing, and a catcher rotating shaft 72 is attached via the rotating shaft holding member 70. As shown in FIG. 5C, a rotary shaft connecting member 74 is attached to the lower portion of the catcher rotary shaft 72 so as to be rotatable in the horizontal direction. A rail connection shaft 75 having a rotation axis orthogonal to the axial direction of the catcher rotation shaft 72 is attached to the rotation shaft connection member 74 via a connection member 76. In the rotary shaft mechanism 35, the catcher rail 36 can be turned in the horizontal direction by the catcher rotary shaft 72, and can be followed even if the catcher rail 36 changes in the vertical direction by the rail connecting shaft 75. .

  A plurality of rollers 81 rotating in the movable range adjusting rail 78 are connected to the rail connecting shaft 75 via a roller connecting member 80. That is, the roller 81 and the catcher rotating shaft 72 are connected by a connecting member including the rotating shaft connecting member 74, the rail connecting shaft 75, and the roller connecting member 80.

  The movable range adjustment rail 78 is fixed along the longitudinal direction of the catcher rail 36 and is suspended by a roller 81. Therefore, the roller 81 rotates in the movable range adjusting rail 78 in the direction of the arrow shown in FIG. 5C, so that the catcher rail 36 fixed to the movable range adjusting rail 78 can be moved in the longitudinal direction. . It is assumed that the movable range adjustment rail 78 is provided with a length that exceeds at least the difference between the longest distance and the shortest distance from the catcher rotation shaft position 33 to the drive mechanism guide rail 39.

  A catcher transport motor 85 is installed at the end of the catcher rail 36. A catcher conveyor belt 86 is wound around a rotating shaft of the catcher conveyor motor 85 between a pulley 90 provided at the other end of the catcher rail 36.

  Inside the catcher rail 36, as shown in FIG. 5B, there is a conveyance path through which the catcher conveyance mechanism connecting member 89 to which the catcher conveyance roller 88 is attached can be conveyed by rotating the catcher conveyance roller 88. Is formed. Two catcher transport rollers 88 are attached to two sides of the catcher transport mechanism connecting member 89 facing each other.

  The catcher transport mechanism connecting member 89 is engaged with the catcher transport belt 86 via a member (not shown). When the catcher transport belt 86 is transported as the catcher transport motor 85 rotates, It is moved in the longitudinal direction.

FIG. 6 is a view for explaining the state of the rotary shaft mechanism 35 according to the turning position of the catcher rail 36.
FIG. 6A shows the rotation shaft mechanism 35 in the case where the catcher rail 36 is located at the position where the distance between the catcher rotation shaft position 33 and the drive mechanism guide rail 39 is the shortest (position indicated by B in FIG. 3). FIG. 6B shows a state in which the catcher rail 36 is located at a position where the distance between the catcher rotation shaft position 33 and the drive mechanism guide rail 39 is the longest (position shown by A and C in FIG. 3). The state of the rotating shaft mechanism part 35 is shown.

  The rotating shaft mechanism 35 in the present embodiment can slide the catcher rail 36 in the longitudinal direction by the movable range adjusting rail 78 and the roller 81. Accordingly, when the catcher rail 36 is turned to a position where the distance between the catcher rotation shaft position 33 and the drive mechanism guide rail 39 is shortened by the drive mechanism 38, the catcher rail 36 is rotated by the catcher as shown in FIG. The roller 81 is rotated in the movable range adjustment rail 78 so as to move in the position direction in which the shaft 72 is provided.

  On the other hand, when the catcher rail 36 is turned to a position where the distance between the catcher rotation shaft position 33 and the drive mechanism guide rail 39 is increased by the drive mechanism 38, as shown in FIG. The roller 81 is rotated in the movable range adjustment rail 78 so as to move in the direction of 15.

  That is, the catcher rail 36 is slidable in the longitudinal direction by the movable range adjusting rail 78 and the roller 81, so that the position of the drive mechanism guide rail 39 where the drive mechanism 38 is located and the catcher as the catcher rail 36 turns. The catcher rail 36 is moved in accordance with the change in the distance from the rotation axis position 33.

  In this manner, in the crane game machine 10 according to the present embodiment, the catcher rail 36 is turned along the drive mechanism guide rail 39 by the drive mechanism 38 provided at the end of the catcher rail 36, whereby the catcher rotation axis position is Even if the distance between the drive mechanism guide rail 39 where the drive mechanism 33 and the drive mechanism 38 are located is changed, the catcher rail 36 is moved in the longitudinal direction so as to follow the drive mechanism guide rail 39 by the movable range adjustment rail 78 and the roller 81. Can be slid. Therefore, by providing the drive mechanism guide rail 39 in parallel to the end portion of the transparent plate 15, the catcher portion 31 can be conveyed by the drive mechanism guide rail 39 to the end portion of the transparent plate 15.

  Further, the mechanism provided in the rotary shaft mechanism portion 35 of the present embodiment can move the catcher rail 36 in the longitudinal direction within the range of the length of the movable range adjusting rail 78, and therefore the drive mechanism due to variations in manufacturing. Even if the mounting position of the guide rail 39 is different for each crane game machine, it can be handled without adjusting the length of the catcher rail 36, the rotary shaft mechanism 35, or the like.

  Similarly, there is a design change with respect to the crane game machine 10, for example, even if the distance from the catcher rotation shaft position 33 to the drive mechanism guide rail 39 is increased in order to widen the prize stand, the movable range adjustment rail If it is within the range of the length of 78, it can respond.

  In the above description, in order to construct a circular crane game machine by combining four terminals, the cross section of one terminal is a quadrant (a sector having a central angle of 90 °). It is also possible to use a sector shape with an angle other than 90 °. If it is the rotating shaft mechanism part 35 in this embodiment, the catcher rail 36 can be rotated according to arrangement | positioning of the drive mechanism guide rail 39. FIG.

  Further, the curved portion of the outer shape of the crane game machine 1 is not limited to an arc. In the rotating shaft mechanism 35 in the present embodiment, the catcher rail 36 can be made to follow the position of the drive mechanism guide rail 39. For example, even if the curved portion is an elliptic curve, it is arranged in parallel with the elliptic curve. The catcher rail 36 can be turned in accordance with the drive mechanism guide rail 39 thus made to reach the catcher portion 31. Thus, since the curved portion of the outer shape of the casing is not limited to the arc, the shape of the prize stand (game field) can be further changed.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
