  As shown in FIG. 23, the screwing member 743 is formed of a cylindrical member having a thread or a screw groove formed on the inner peripheral surface, and a ball screw 741 is inserted and screwed therein. A flange portion 744 is formed integrally with the screwing member 743 at the lower end portion of the screwing member 743. As shown in FIG. 22, through holes 744 a are formed in the flange portion 744 at substantially equal intervals along the circumferential direction. In addition, slits 744 b are formed at substantially equal intervals along the circumferential direction of the outer peripheral edge of the flange portion 744. A projection (not shown) formed on the inner peripheral surface of the lower cover member 51b is fitted into the slit 744b, so that the lower cover member 51b is attached to the operating unit 7 (main body 51).

  The cylindrical member 745 is provided concentrically with the screwing member 743, and a screw hole (not shown) is formed on the lower surface thereof corresponding to the through hole 744a. The cylindrical member 745 is fixed to the flange portion 744 by inserting the screw 745b through the through hole 744a and screwing it into the screw hole. The cylindrical member 745 is inserted inside the upper pressing member 72 and the lower pressing member 73. In other words, the upper pressing member 72 and the lower pressing member 73 are located on the outer periphery of the cylindrical member 745. The upper pressing member 72 and the lower pressing member 73 are not fixed to the cylindrical member 745 (provided in a non-fixed manner). Further, screw holes 745a are formed on the upper surface of the cylindrical member 745 at substantially equal intervals along the circumferential direction thereof.

  A ring-shaped member 746 is provided at the upper end of the cylindrical member 745. The ring-shaped member 746 has a through hole 746a corresponding to the screw hole 745a. The ring-shaped member 746 is fixed to the cylindrical member 745 by inserting the screw 745c through the through-hole 746a and screwing it into the screw hole 745a. A coil spring 747 is provided concentrically with the cylindrical member 745 between the ring-shaped member 746 and the flange portion 744. The upper end portion of the coil spring 747 is in contact with the lower surface of the flange portion 732 of the lower pressing member 73, and the lower end portion is in contact with the upper surface of the flange portion 744.

  In such a configuration, the flange portion 744 is formed integrally with the screwing member 743, and is screwed to the cylindrical member 745, and the ring-shaped member 746 is also screwed to the cylindrical member 745. Therefore, when the ball screw 741 rotates, the screwing member 743 moves along the vertical direction (vertical direction). At this time, the flange portion 744, the cylindrical member 745, and the ring-shaped member 746 are also screwed members. It moves along the vertical direction together with 743. That is, in the present embodiment, the screwing member 743, the flange portion 744, the cylindrical member 745, and the ring-shaped member 746 constitute a moving structure 740 that moves along the vertical direction by the rotation of the ball screw 741.

  The upper pressing member 72, the lower pressing member 73, and the coil spring 747 are located between the flange portion 744 and the ring-shaped member 746, and are separated from the moving structure 740 (the operating mechanism 74) due to their presence. Is prevented. That is, in the present embodiment, the flange portion 744 and the ring-shaped member 746 constitute a separation preventing portion that prevents the upper pressing member 72 and the lower pressing member 73 from being detached from the operation mechanism 74.

  The upper pressing member 72 and the lower pressing member 73 are provided in a non-fixed manner with respect to the cylindrical member 745 (moving structure 740), but are urged vertically upward by a coil spring 747. As a result, the upper pressing member 72 and the lower pressing member 73 are held between the ring-shaped member 746 and the coil spring 747. For this reason, when the moving structure 740 moves (displaces) along the vertical direction, the upper pressing member 72 and the lower pressing member 73 can also move (displace) along the vertical direction.

  When the moving structure 740 moves vertically downward (in a direction away from the fixed portion 71), the upper pressing member 72 presses the base end portion (roller 532) of the arm 52 and moves (displaces) vertically downward. On the other hand, when the moving structure 740 moves vertically upward (direction approaching the fixed portion 71), the lower pressing member 73 presses the base end portion of the arm 52 and moves (displaces) vertically upward.

  As described above, each arm 52 is configured to rotate about the pin 533 as a rotation center. Therefore, when the base ends of the two arms 52 move vertically upward, the two arms 52 can move in the direction in which the claw portions 56 provided at the distal end approach each other (closed direction) and grip the prize. it can. On the other hand, when the base ends of the two arms 52 move vertically downward, the two arms 52 move in a direction (opening direction) in which the claw portions 56 are separated from each other, and can release the prize.

  The guide member 748 has a function of guiding the movement of the moving structure 740 along the vertical direction. The guide member 748 has a cylindrical shape as shown in FIG. 21, and a screw hole 748 a is formed on the upper surface corresponding to the through hole 711 b of the fixing portion 71. The guide member 748 is fixed to the fixing portion 71 by inserting the screw 748b into the through hole 711b and screwing it into the screw hole 748a. The lower end side of the guide member 748 is inserted between the screwing member 743 and the cylindrical member 745.

  Further, a groove (concave portion) 748c is formed on the outer peripheral surface of the guide member 748 along the vertical direction, and a convex strip (inserted into the groove 748c along the vertical direction is formed on the inner peripheral surface of the cylindrical member 745. Ribs) 745d are formed. By inserting the protrusion 745d into the groove 748c, the cylindrical member 745 (moving structure 740) does not rotate around the ball screw 741 even if the ball screw 741 rotates. For this reason, the moving structure 740 can be smoothly moved along the vertical direction. That is, in the present embodiment, the protrusion 745d and the groove 748c constitute a rotation blocking portion that blocks the rotation of the moving structure 740.

  The connecting portion 510, the drive unit 6, and the operation unit 7 as described above are coupled by the coupling structure 8. As shown in FIG. 19, the connecting structure 8 includes a fixing plate 81 for fixing the connecting portion 510, a connecting plate 82 for connecting the driving unit 6 and the operating unit 7, and a fixing plate 81, the driving unit 6 and the connecting plate. The fixing structure 83 is configured to fix the connecting plate 82, and the screw 84 is used to fix the connection plate 82 to the operation unit 7.

  The fixed plate 81 has a square shape in plan view, and a connecting portion 510 is fixed at the center thereof. In addition, through holes 81 a are formed in the four corners of the fixing plate 81, respectively. The connection plate 82 includes an octagonal bottom portion 821 in a plan view and arm portions 822 that are erected from the upper surface of the bottom portion 821 on four sides of the bottom portion 821. A through hole 821a into which the gear 749 of the operating unit 7 is inserted is formed at the center of the bottom 821, and a through hole 821b corresponding to the screw hole 711c is formed on the outer periphery of the through hole 821a. The screw 84 is inserted into the through hole 821b and screwed into the screw hole 711c. Thereby, the connection board 82 is fixed to the fixing | fixed part 71 (operation unit 7). The arm portion 822 is bent at a substantially right angle toward the outside in the middle of the vertical direction, and a through hole 822a is formed at a tip portion thereof (an end portion opposite to the bottom portion 821).

  The fixing structure 83 includes long bolts 831, nuts 832, and screws 833. A screw thread or a screw groove is formed on the outer peripheral surface of the lower portion 831a of the long bolt 831, and a screw hole 831b is formed on the upper end surface of the long bolt 831. The lower portion 831a of the long bolt 831 is inserted into the through hole 602a of the casing 60 and the through hole 822a of the connection plate 82, and the nut 832 is screwed together. On the other hand, the screw 833 is inserted into the through hole 81 a of the fixing plate 81 and screwed into the screw hole 831 b of the long bolt 831. As a result, the connecting portion 510, the drive unit 6, and the operating unit 7 are coupled (fixed) by the coupling structure 8.

  Each member which comprises such a main body 51 can be formed with a hard resin material, a metal material, a ceramic material etc., for example. Moreover, although the screwing member 743 and the flange part 744 are integrally formed, these are comprised separately and may mutually be joined (connected). Furthermore, although the flange part 744 and the cylindrical member 745 are comprised by the different body, these may be formed integrally.

  Next, the opening / closing operation | movement of the arm 52 is demonstrated based on FIGS. When the ball screw 741 is rotated in a predetermined direction from the state shown in FIG. 23 and the moving structure 740 is moved vertically upward, the lower pressing member 73 that is pressed vertically upward by the urging force of the coil spring 747 is: The base end portion (roller 532) of the arm 52 is pressed vertically upward to move vertically upward. As a result, the two arms 52 rotate around the pin 93 as a rotation center, and the claw portions 56 (tip portions) approach each other. That is, the arm 52 is closed.

  At this time, the base end portion of the arm 52 pressed vertically upward by the lower pressing member 73 presses the upper pressing member 72 vertically upward, but the upper pressing member 72 includes a ring-shaped member 746. Abut. For this reason, the upper pressing member 72 and the lower pressing member 73 do not fall off the moving structure 740.

  When the moving structure 740 is further moved vertically upward while maintaining this state, the upper pressing member 72 comes into contact with the lower surface of the peripheral wall plate 712 of the fixing portion 71 as shown in FIG. Thereby, the further upward movement of the upper pressing member 72 and the lower pressing member 73 is restricted (blocked). In the present embodiment, when the upper pressing member 72 and the lower pressing member 73 reach the position (first position) shown in FIG. 24, the claw portions 56 (tip portions) of the two arms 52 come into contact with each other. It is configured. That is, the arm 52 is in a closed state and can hold a prize.

  When the moving structure 740 is further moved vertically upward, the upper wall pressing member 72 and the lower pressing member 73 are restricted from moving vertically upward by the peripheral wall plate 712, so that the coil spring 747 is gradually compressed and is moved by the coil spring 747. The downward pressing force of the lower pressing member 73 gradually increases. As a result, the pressing force of the lower pressing member 73 on the base end of the arm 52 in the vertical upward direction gradually increases, and the gripping force of the prize by the arm 52 also increases. Therefore, by adjusting the vertically moving distance of the moving structure 740 from the state shown in FIG. 24, the gripping force of the prize by the arm 52 can be changed (adjusted).

  Conversely, when the ball screw 741 is rotated in the opposite direction from the state shown in FIG. 25, the moving structure 740 moves vertically downward to the state shown in FIG. When the moving structure 740 is further moved vertically downward from this state, the upper pressing member 72 is pressed vertically downward by the ring-shaped member 746, and the upper pressing member 72 is a base end portion (roller) of the arm 52. 532) is pushed downward in the vertical direction to move downward in the vertical direction. As a result, the two arms 52 rotate around the pin 93 as a rotation center, and the claw portions 56 (tip portions) are separated from each other. That is, the arm 52 is opened.

  Then, in a state where the upper pressing member 72 and the lower pressing member 73 have reached the position shown in FIG. 23 (second position vertically below the first position), the distal end portions (the other end portions) of the arms 52 are After sufficiently separating, the arm 52 is opened, and the holding of the prize (the object to be held) by the arm 52 is released.

  According to this configuration, the movement (displacement) along the vertical direction of the base end portion of the arm 52 is performed in a state where the roller 532 is sandwiched between the upper pressing member 72 and the lower pressing member 73. Is pivotable about the pin 533 as a pivot center. For this reason, this movement is made smoothly.

  Further, the suspension member 91 can be separated from the operating unit 7 (fixed portion 71) together with the arm 52 by removing the screw 92. On the other hand, when the arm 52 is fixed to the operation unit 7, the base end portion (roller 532) of the arm 52 is inserted between the upper pressing member 72 and the lower pressing member 73, and the suspension member 91 is Attached to the fixing portion 71 with a screw 92. According to such a prize gripping part 5, the arm 52 can be attached to and detached from the main body 51 by an extremely simple operation.

  Moreover, according to this structure, the base end part (roller 532) of the arm 52 can be pressed at an arbitrary position in the circumferential direction of the upper pressing member 72 and the lower pressing member 73. Therefore, in theory, the arm 52 can be attached to any position in the circumferential direction of the operating unit 7 (fixed portion 71). However, in the illustrated configuration, a set of screw holes arranged in the vertical direction. It can be attached to 24 positions of the fixing portion 71 where 712a is formed. In the illustrated configuration, 24 arms 52 can be attached to the fixing portion 71. In the present embodiment, the width (size) of the arms 52 and the suspension member 91 is taken into consideration, as shown in FIG. In addition, a maximum of six arms 52 can be attached to the fixing portion 71. 28, the three arms 52 may be attached to the fixing portion 71, or the four arms 52 may be attached to the fixing portion 71 in the arrangement shown in FIG. It may be.

  Furthermore, one arm 25 may be attached to the fixing portion 71. In this case, a portion for hooking the arm 52 on the prize is provided, or the prize is slid on the placing plate 10 by the prize moving mechanism 500.

  Moreover, the prize gripping part 5 may have a detection mechanism 57 for detecting the position of the arm 52 as shown in FIGS. The detection mechanism 57 includes a sensor unit 571, a holding plate 572 that holds the sensor unit 571, a screw 577 that fixes the holding plate 572 to the suspension member 91, a shield 578, and a shield 578 that is attached to the shoulder 53. A screw 579 for fixing to the main body 531 is provided. The sensor unit 571 includes a light emitting element 571a, a light receiving element 571b disposed to face the light emitting element 571a, and engagement claws 571c and 571d.

  The holding plate 572 is attached to the suspension member 91, the contact portion 573 that contacts the suspension member 91, the attachment portion 575 that is separated from the suspension member 91 and attaches the sensor unit 571, and the contact portion 573. And a connecting portion 576 for connecting the mounting portion 575 to each other. The connecting portion 576 is disposed so as to be substantially perpendicular to the contact portion 573 and the attachment portion 575, and the contact portion 573 and the attachment portion 575 are disposed substantially in parallel. That is, the holding plate 572 has a stepped shape when viewed from the side.

  The contact portion 573 is formed with a large opening 573a penetrating therethrough. The screw 92 can be attached and removed through the large opening 573a. In addition, side plates 574 are provided at both ends of the contact portion 573 so as to stand up toward the suspension member 91. A through hole 574 a is formed in the side plate portion 574, and a screw hole 912 b is formed in the upper portion of the side plate 912 of the suspension member 91. The screw 577 is inserted into the through hole 574a and screwed into the screw hole 912b. Thereby, the holding plate 572 is fixed to the suspension member 91.

  The attachment portion 575 is formed with through holes 575a and 575b provided in the width direction. The engaging claw 571c engages with the edge portion defining the through hole 575a of the mounting portion 575, and the engaging claw 571d engages with the edge portion defining the through hole 575b of the mounting portion 575, whereby the sensor portion 571 is , Fixed to the holding plate 572.

  The shield 578 includes a fixed plate 578a and a shield plate 578b standing from the fixed plate 578a. A through hole 578 c is formed in the fixing plate 578 a, while a screw hole 531 e is formed in the upper surface of the main body 531 of the shoulder portion 53. The screw 579 is inserted into the through hole 578c and screwed into the screw hole 531e. Thereby, the shielding body 578 is fixed to the shoulder portion 53.

  As shown in FIG. 26, when the arm 52 is in the open state, the shielding plate 578b is inserted between the light emitting element 571a and the light receiving element 571b. For this reason, the light emitted from the light emitting element 571a is blocked (blocked) from reaching the light receiving element 571b. On the other hand, when the arm 52 is in the closed state, the shielding plate 578b is not positioned between the light emitting element 571a and the light receiving element 571b. For this reason, the light emitted from the light emitting element 571a is allowed to reach the light receiving element 571b. According to such a configuration, the state where the shielding plate 578b is positioned to block the light emitted from the light emitting element 571a can be set as the open state (initial position) of the arm 52. Thereby, the opening / closing operation | movement of the arm 52 can be performed more correctly.

  As shown in FIG. 31, coil springs (biasing members) that bias the central portion of the arm 52 so as to approach the suspension member 91 are, for example, the arm portion 54 of the arm 52 and the side plate 912 of the suspension member 91. May be provided so as to be connected to each other. In this case, the arm 52 is opened when the coil spring is in the natural state shown in FIG. When the base end portion (roller 532) of the arm 52 is pressed vertically upward by the lower pressing member 73 and moved vertically upward, the two arms 52 rotate around the pin 93 as a center of rotation. The nail | claw part 56 (tip part) approaches and it will be in a closed state. On the other hand, the arm 52 is urged by a coil spring so that the central portion thereof approaches the suspension member 91, and thus the pressure toward the vertically upper portion of the base end portion of the arm 52 by the lower pressing member 73 is released. Only the two arms 52 are opened. Therefore, in this case, the upper pressing member 72 may be omitted.

  Also, as shown in FIG. 32, a coil spring (biasing member) that urges the base end of the arm 52 to be pulled vertically upward is suspended from, for example, a portion between the pin 533 and the pin 93 of the arm 52. You may make it provide so that the side plate 912 of the lower member 91 may be connected. In this case, when the coil spring is in the natural state shown in FIG. 32, the arm 52 is closed. When the upper end pressing member 72 presses the base end portion (roller 532) of the arm 52 downward in the vertical direction and moves it vertically downward, the two arms 52 rotate around the pin 93, and their claws. The portions 56 (tip portions) are separated from each other and are in an open state. On the other hand, since the arm 52 is urged by a coil spring so that the base end portion is pulled up vertically, it is only necessary to release the downward pressure of the base end portion of the arm 52 by the upper pressing member 72. The two arms 52 are closed. Therefore, in this case, the lower pressing member 73 may be omitted.

Second Embodiment
Next, the second embodiment of the game apparatus of the present invention will be described, focusing on differences from the first embodiment, and description of similar matters will be omitted. FIG. 33 is a perspective view showing a second embodiment of the game apparatus of the present invention, and FIG. 34 is a cross-sectional view taken along line AA in FIG. In FIG. 33, the left-right direction is referred to as “X-axis direction”, the front-rear direction is referred to as “Y-axis direction”, and the up-down direction is referred to as “Z-axis direction”.

  In the game device 100 of the second embodiment, the configuration of the positioning mechanism 1 is different, and the rest is the same as the game device 100 of the first embodiment. That is, the positioning mechanism 1 of the second embodiment extends from the bottom surface of the top plate portion 101 of the mounting plate 10 and the pair of guide rails 41 that extend along the X-axis direction (or Y-axis direction) and face each other. A ridge 42 that is erected and is inserted into the guide rail 41, a male screw portion 43 that protrudes from the upper surface of the lower apparatus body 920, and a female screw portion 44 that is screwed into the male screw portion 43. ing.

  In addition, a long through hole 106 is formed in the top plate portion 101 along the extending direction (X-axis direction or Y-axis direction) of the guide rail 41. Both ends of the through hole 106 are not open to the edge of the top plate portion 101. The male screw portion 43 is inserted into the through hole 106, and the female screw portion 44 is screwed to the tip portion and tightened. Thereby, the mounting plate 10 can be fixed to the lower apparatus main body 920.

  In such a positioning mechanism 1, the mounting plate 10 can be slid in the horizontal direction and fixed at a desired position by operating the female screw portion 44. That is, the positioning mechanism 1 can take different states (forms) by operating the female screw portion 44. For example, the left positioning mechanism 1 in FIG. 14 can take various different states (forms) from the state in which the ridge 42 is positioned rearward to the state in which it slides and is positioned forward. Therefore, by changing the state of the positioning mechanism 1 and positioning the mounting plate 10 with respect to the opening 901, in addition to the size of the opening 901 exposed from the mounting plate 10 in plan view, the shape and position are changed. can do. Thereby, it is possible to provide the game device 100 that does not get tired by easily changing the layout of the game space 910b with a simple configuration (one mounting board 10).

<Third Embodiment>
Next, a third embodiment of the game apparatus of the present invention will be described. The description will focus on differences from the first embodiment, and description of similar matters will be omitted. 35 is a perspective view showing a state in which the side wall plate is attached to the mounting plate, FIG. 36 is a plan view of the mounting plate shown in FIG. 35, and FIG. 37 is a sectional view taken along line BB in FIG. .

  In the game device 100 of the third embodiment, a side wall plate is added to the placement plate, and the other portions are the same as those of the game device 100 of the first embodiment. That is, in the present embodiment, the side wall plate 11 is attached to the four sides (side portions) of the mounting plate 10 via the rotation mechanism 12. The rotating mechanism 12 includes a cylindrical member 121 to which the side wall plate 11 is joined, a columnar member 122 inserted through the cylindrical member 121, and a fixing portion 123 that fixes the columnar member 122 to the mounting plate 10. It has.

  The fixing portion 123 includes a plate-like fixing member 123a bent substantially at a right angle in the middle of the longitudinal direction, and a screw 123b. The fixing member 123a is screwed to the notches 10a formed at the four corners of the mounting plate 10. Further, through holes (not shown) are formed at both ends of the fixing member 123a, and screw holes (not shown) to be screwed with the screws 123b are formed at both ends of the cylindrical member 122. . The cylindrical member 122 is fixed to the mounting plate 10 by inserting the screw 123b through the through hole of the fixing member 123a and screwing it into the screw hole of the cylindrical member 122. Note that the columnar member 122 is not rotated about the screw 123b.

  According to the rotation mechanism 12, the side wall plate 11 rotates with respect to the mounting plate 10 by the cylindrical member 121 rotating about the columnar member 122 as the rotation center. The length of the cylindrical member 121 is set slightly shorter than the length of the columnar member 122. For this reason, the cylindrical member 121 can rotate with respect to the columnar member 122 without interfering with the fixing member 123a. Further, the two lower corners of the side wall plate 11 are notched so that they are prevented from interfering with each other when the side wall plate 11 is rotated with respect to the mounting plate 10. .

  As shown in FIG. 37, a screw hole 11a is formed at a predetermined position of the side wall plate 11, and the cylindrical member 121 penetrates the trunk portion at a position corresponding to the screw hole 11a. A screw hole 121a is formed. A screw 124 that is screwed into the screw hole 11a and the screw hole 121a is provided. The cylindrical member 122 is formed with a first recess 122a, a second recess 122b, and a third recess 122c into which the tip of the screw 124 is inserted along the circumferential direction thereof. In the present embodiment, the first recess 122a is formed substantially parallel to the mounting plate 10, and the second recess 122b is formed to be inclined downward by 30 ° with respect to the first recess 122a. The recess 122c is inclined 45 ° downward with respect to the first recess 122a.

  According to such a configuration, when the distal end portion of the screw 124 is inserted into the first recess 122a, the distal end portion of the screw 124 engages with the step between the first recess 122a and the second recess 122b. For this reason, the rotation of the cylindrical member 121 relative to the columnar member 122 is restricted. At this time, the side wall plate 11 joined to the cylindrical member 121 is fixed at approximately 90 ° with respect to the mounting plate 10 (see FIG. 37A). Similarly, when the tip of the screw 124 is inserted into the second recess 122b, the tip of the screw 124 engages with the step between the second recess 122b and the third recess 122c. It fixes with respect to the mounting board 10 (refer FIG.37 (b)).

  When the tip of the screw 124 is inserted into the third recess 122c, the tip of the screw 124 engages with the step between the third recess 122c and the outer peripheral surface of the cylindrical member 122, and the side wall plate 11 The fixing plate 10 is fixed at an angle of approximately 45 ° (see FIG. 37D). In the present embodiment, the cylindrical member 121 is provided with a protruding piece 121b protruding from the outer peripheral surface, and the protruding piece 121b has an angle formed by the side wall plate 11 and the mounting plate 10 of approximately 30. It is configured to contact the edge portion 102 of the mounting plate 10 in a state where the angle is set. The contact of the projecting piece 122d with the edge portion 102 restricts the rotation of the cylindrical member 121 with respect to the columnar member 122, and the side wall plate 11 is fixed to the mounting plate 10 at approximately 30 °. (See FIG. 37 (d)).

  That is, the rotation mechanism 12 of the present embodiment can be adjusted in four steps within the range of 30 to 90 ° (angle θ in FIG. 37) between the mounting plate 10 and the side wall plate 11. The rotation mechanism 12 may be configured to be adjustable in two or three stages, and may be configured to be adjustable in five or more stages, between the mounting plate 10 and the side wall plate 11. . In the above configuration, an adjustment structure for adjusting the rotation angle of the side wall plate 11 with respect to the mounting plate 10 is mainly configured by the screw 124, the protruding piece 121b, and the first to third recesses 122a to 122c. .

  In addition, each member which comprises the side wall board 11 and the rotation mechanism 12 can be formed with a hard resin material, a metal material, a ceramic material, wood, these composite materials, etc., for example. Moreover, although the side wall board 11 and the cylindrical member 121 are comprised by the different body, these may be formed integrally.

  By providing such a side wall plate 11, it is possible to prevent a prize placed on the placement plate 10 from dropping unintentionally from the placement plate 10. Even when the mounting plate 10 is disposed to be inclined with respect to the opening 901, the prize can be held on the mounting plate 10. In particular, since the side wall plate 11 is provided so as to be rotatable with respect to the mounting plate 10 and can be fixed at a predetermined angle, it is possible to adjust the degree of difficulty in obtaining a prize, and to be more tired. A game apparatus 100 can be provided.

  In addition, it cannot be overemphasized that you may make it prepare the angle which the four side wall plates 11 each make with the mounting plate 10 separately. Further, the side wall plate 11 may be provided on one side, two sides, or three sides of the four sides of the mounting plate 10. Further, the range in which the angle formed between the mounting plate 10 and the side wall plate 11 can be adjusted can be any angle (for example, about 10 to 120 °), but is preferably 30 to 90 °. More preferably, it is 45 to 90 °. Thereby, the said effect can be heightened more.

  Further, the side wall plate 11 may not be rotatable with respect to the mounting plate 10, that is, may be provided fixedly. In this case, an attachment structure for attaching the mounting plate 10 and the side wall plate 11 is provided. As such an attachment structure, for example, a combination of a convex portion provided on one of the mounting plate 10 and the side wall plate 11 and a concave portion that engages with the convex portion can be mentioned. In this case, a plurality of mounting structures are provided so that the angle formed between the mounting plate 10 and the side wall plate 11 can be changed in multiple stages, preferably in the range of 30 to 90 ° (more preferably 45 to 90 °). It is preferable to provide them.

  Instead of the configuration as described above, the side wall plate 11 and the rotation mechanism 12 may be configured as shown in FIGS. The rotation mechanism 12 of this configuration example includes a columnar member 125 that is provided so as to be rotatable with respect to the fixing member 123a.

  As shown in FIG. 39, a plurality (two or four) of screw holes 125a are formed in the body portion of the columnar member 125 along the longitudinal direction thereof. The side wall plate 11 is formed with a plurality of through holes 11b. The side wall plate 11 is fixed to the columnar member 125 by inserting the screw 124 into the through hole 11b and screwing it into the screw hole 125a. The plurality of through-holes 11b are formed at substantially equal intervals along the longitudinal direction of the side wall plate 11 with a set of three through-holes 11b arranged along the vertical direction. Thereby, in the up-down direction, the position of the side wall plate 11 with respect to the mounting plate 10 can be changed in three steps (multiple steps).

  Further, at both ends of the cylindrical member 125, a reduced diameter portion 126 having a diameter smaller than the diameter of the body portion is formed. A screw hole 126 a is formed at the center of the end surface of the reduced diameter portion 126. On the other hand, a bearing 123c into which the reduced diameter portion 126 is inserted is recessed in the inner surface of the fixing member 123a. A through hole 123d is formed at the center of the bottom of the bearing 123c. The reduced diameter portion 126 is inserted into the bearing 123c, and in this state, the screw 123b is inserted into the through hole 123d, and the tip portion is screwed into the screw hole 126a and tightened. Thereby, the columnar member 125 can be fixed to the fixing member 123a. Further, by weakening the degree of screwing of the screw 123b into the screw hole 126a, the columnar member 125 can be rotated around the screw 123b as shown in FIG. 40 (b).

  A plurality of hemispherical convex portions 126b are formed on the end surface of the reduced diameter portion 126 along the outer peripheral portion thereof. On the other hand, a plurality of concave portions 123e having a shape corresponding to the convex portions 126b are formed along the outer peripheral portion of the bottom portion of the bearing 123c. These recesses 123e are provided close to each other (continuous). In a state where the columnar member 125 is fixed to the fixing member 123a, the convex portion 126b is inserted into the concave portion 123e. Thus, the rotation angle of the columnar member 125 with respect to the fixing member 123a can be adjusted in multiple stages.

  Further, a pair of flange portions 127 are formed integrally with the cylindrical member 125 at both ends of the cylindrical member 125, respectively. The flange portion 127 has a top surface 127a and an inclined surface 127b that is inclined with respect to the top surface 127a. On the other hand, as shown in FIG. 40, a protrusion 107 protruding toward the side is provided on the placement plate 10 (edge 102). The lower surface of the protruding portion 107 constitutes an inclined surface 107 a that is inclined at approximately 45 ° with respect to the side surface of the mounting plate 10.

  According to the rotation mechanism 12, the columnar member 125 rotates about the screw 123 b as the rotation center, whereby the side wall plate 11 rotates with respect to the mounting plate 10. Note that the side wall plate 11 is placed so that the angle θ becomes larger (greater than 90 °) from the state in which the side wall plate 11 forms approximately 90 ° with respect to the placement plate 10 (see FIG. 40A). 10, the inclined surface 127 b of the upper flange portion 127 of the cylindrical member 125 comes into contact with the inclined surface 107 a of the protruding portion 107 of the mounting plate 10. For this reason, the rotation of the columnar member 125 with respect to the fixing member 123a is restricted. On the other hand, the side wall plate 11 is placed so that the angle θ becomes smaller (below 45 °) from the state in which the side wall plate 11 forms approximately 45 ° with respect to the placement plate 10 (see FIG. 40B). 10, the inclined surface 127 b of the lower flange portion 127 of the columnar member 125 comes into contact with the side surface of the mounting plate 10 (the edge portion 102). For this reason, the rotation of the columnar member 125 with respect to the fixing member 123a is restricted.

  In other words, the rotation mechanism 12 of the present configuration example can be adjusted in multiple stages within the range of 45 to 90 ° (angle θ in FIG. 40) between the mounting plate 10 and the side wall plate 11. In the above configuration, an adjustment structure that adjusts the rotation angle of the side wall plate 11 with respect to the mounting plate 10 is mainly configured by the protruding portion 107 and the flange portion 127.

  The structure and game device of the present invention have been described above with reference to the illustrated embodiment, but the present invention is not limited to this. For example, each part of the structure and the game device can be replaced with any structure that can exhibit the same function. Moreover, arbitrary components may be added. Moreover, in this invention, you may make it combine the arbitrary structures of the said 1st-3rd embodiment. Furthermore, the structure of the present invention can be used for a prize grip portion of a game apparatus as described above, and for example, can be used for an industrial robot.
