[Modes for carrying out the invention]

[0012] Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, an example is described in which the prize-winning game device according to the present invention is applied to a prize-winning game device 1 capable of executing a prize-winning game. The "Prize Acquisition Game" is a game in which the player (user) can acquire prize P by operating the control unit 16 to activate the prize gripping unit 410, causing the prize P placed in the prize placement area AE to fall into the opening area OE. "Prize Points" can be items that are awarded to the player upon acquisition, or items that are not awarded to the player upon acquisition but can be exchanged for other items (items awarded to the player) after acquisition. Either is acceptable.

[0013] (Configuration of prize-winning game device 1) First, let's explain the configuration of the prize-winning game device 1. Figure 1 is a perspective view showing the external appearance of the prize-winning game machine 1. In the example shown in Figure 1, two prize-winning game machines 1 are configured within a single enclosure 10. That is, a common enclosure 10 is used for the two prize-winning game machines 1. However, it is also possible for one prize-winning game machine 1 to be configured within a single enclosure 10. Furthermore, it is also possible for three or more prize-winning game machines 1 to be configured within a single enclosure 10. The following description explains the configuration of each prize-winning game device 1.

[0014] As shown in Figure 1, the prize-winning game device 1 is composed of a housing 10, a base frame unit 20 located inside the housing 10, a prize placement mechanism 30 attached to the base frame unit 20, a crane unit 40 attached to the base frame unit 20, and a control board 50 (see Figure 27) located inside the housing 10.

[0015] (Cabinet 10) First, let me explain the configuration of the enclosure 10. The cabinet 10 is formed in a box shape. Inside the cabinet 10 is a game area (play area) GE where the prize-winning game takes place. The cabinet 10 consists of an upper cabinet 11 and a lower cabinet 12. The rear, left side, and right side of the upper casing 11 are each made of transparent sheet material such as glass or acrylic. This allows the player to see the game area GE, which is located inside the casing 10, from the outside of the casing 10. The upper casing 11 has an open front. A pair of sliding doors 510 and 520 are provided on the front of the upper casing 11. Each sliding door 510 and 520 consists of an aluminum frame 511 and 521 (see Figures 28, 30, 32, and 34) and glass plates 512 and 522 (see Figures 28, 30, 32, and 34) fitted inside the frame 511 and 521. Each sliding door 510 and 520 is a sliding door that opens and closes along the left-right direction, making it possible to open and close the front of the upper casing 11. When viewed from the front, sliding door 510 can open and close the front of the game area GE corresponding to the prize-winning game device 1 on the left side. On the other hand, sliding door 520 can open and close the front of the game area GE corresponding to the prize-winning game device 1 on the right side when viewed from the front.

[0016] The upper housing 11 is provided with an upper guide rail (not shown) and a lower guide rail 530 (see Figures 28, 30, 32, and 34). The upper and lower guide rails 530 guide the opening and closing of each sliding door 510, 520. The upper guide rail is formed in a straight line and is positioned along the upper edge of the inner periphery on the front side of the upper housing 11. The lower guide rail 530 is formed in a straight line and is positioned along the lower edge of the inner periphery on the front side of the upper housing 11. The lower surface of the upper guide rail is provided with a guide groove (not shown) extending along its longitudinal direction. The upper surface of the lower guide rail 530 is also provided with a rail section (not shown) extending along its longitudinal direction. The rail section is positioned to protrude upward from the upper surface of the lower guide rail 530. Each sliding door 510, 520 is provided with a roller device 513, 523 (see Figures 28, 30, 32, and 34) on its bottom surface. The roller devices 513, 523 are located inside the frames 511, 521. Each roller device 513, 523 includes a rail receiving portion (not shown) that receives the rail portion, and a roller (not shown) that rolls on the upper surface of the rail portion. The rail receiving portion includes a pair of side plates. Each side plate is positioned between the outer surface of the rail portion and the inner surface of the frames 511, 521, preventing contact between the outer surface of the rail portion and the inner surface of the frames 511, 521. In this embodiment, the rail receiving portion is made of resin. This prevents the aluminum rail portion and the frames 511, 521 from rubbing against each other, and prevents the operator (manager) from being injured by the polished corners of the rail portion. Each sliding door 510, 520 is supported so as to be openable and closable by an upper guide rail and a lower guide rail 530. Specifically, the upper edge of each sliding door 510, 520 is supported by the upper guide rail by being inserted into a guide groove. The lower edge of each sliding door 510, 520 is supported by the lower guide rail 530 by having the rail portion inserted into the rail receiving portion. In this case, the load of each sliding door 510, 520 is supported by the rail portion via the rollers of each roller device 513, 523. This makes it possible to open and close each sliding door 510, 520 smoothly. By opening each sliding door 510, 520, the operator can arrange and move prizes P, configure and change the prize arrangement mechanism 30, etc., in the game area GE corresponding to each prize acquisition game device 1.

[0017] A control panel 13 is provided on the front of the lower casing 12. The control panel 13 is equipped with a coin slot 14, a credit display unit 15, and an operation unit 16. The coin slot 14 allows players to insert coins. By inserting coins into the coin slot 14, players can acquire credits to play the prize-winning game. Alternatively, a payment device for electronic money using storage media such as prepaid cards or credit cards may be provided, allowing players to acquire credits through electronic money payments. The credit display unit 15 shows the remaining number of credits the player has earned. That is, each time a player earns credits by inserting a coin into the coin slot 14, the remaining number of credits displayed on the credit display unit 15 increases. Also, each time a prize-winning game is played, the remaining number of credits displayed on the credit display unit 15 decreases. The control unit 16 receives input from the player. The control unit 16 includes a first operation button 16a and a second operation button 16b. Each operation button 16a and 16b can be pressed by the player. The first operation button 16a receives input to move the prize gripping unit 410 along the X direction (left-right direction) during the prize winning game. The second operation button 16b receives input to move the prize gripping unit 410 along the Y direction (depth direction) during the prize winning game. The operation unit 16 may also be configured to include a third operation button that accepts the operation to move the prize gripping unit 410 along the Z direction (up and down direction) during the prize winning game. Alternatively, the operation unit 16 may be configured to include a joystick that accepts the operation to move the prize gripping unit 410 along the horizontal direction (left and right direction and depth direction) and a down button that accepts the operation to move the prize gripping unit 410 along the Z direction (up and down direction) during the prize winning game. Furthermore, a prize dispensing opening 17 is provided on the front of the lower casing 12, which communicates with the opening area OE. Below the prize placement mechanism 30, a prize slope (not shown) is positioned. Prizes P that fall into the opening area OE are guided to the prize dispensing opening 17 by the prize slope. This allows the player to obtain the prize P from the prize dispensing opening 17. Furthermore, a door 19 is provided on the front of the lower housing 12. Various control boards (control board 50, etc.) are arranged inside the door 19.

[0018] (Locking mechanism 600, 700) Next, the configuration of the locking mechanisms 600 and 700 will be explained. Figure 28 is a rear view showing the locking mechanism 600 with the latch portion 620 displaced to the locked position. Figure 29 is a rear view showing the latch lock body 610 of the locking mechanism 600 shown in Figure 28. Figure 30 is a rear view showing the locking mechanism 600 with the latch portion 620 displaced to the unlocked position. Figure 31 is a rear view showing the latch lock body 610 of the locking mechanism 600 shown in Figure 30. Figure 32 is a rear view showing the locking mechanism 700 with the latch portion 720 displaced to the locked position. Figure 33 is a rear view showing the latch lock body 710 of the locking mechanism 700 shown in Figure 32. Figure 34 is a rear view showing the locking mechanism 700 with the latch portion 720 displaced to the unlocked position. Figure 35 is a rear view showing the latch lock body 710 of the locking mechanism 700 shown in Figure 34. The housing 10 is individually equipped with a locking mechanism 600 capable of locking and unlocking the sliding door 510, and a locking mechanism 700 capable of locking and unlocking the sliding door 520. This makes it possible to lock and unlock the sliding door 510 and the sliding door 520 individually. In the following explanation, the direction in which each sliding door 510, 520 is opened will be referred to as the "opening direction." Conversely, the direction in which each sliding door 510, 520 is closed will be referred to as the "closing direction." Specifically, the sliding door 510 opens and closes the front of the game area GE, which corresponds to the prize-winning game machine 1 on the left side when viewed from the front. In this case, the sliding door 510 opens by sliding to the right when viewed from the front, and closes by sliding to the left. In other words, for the sliding door 510, the opening direction is to the right, and the closing direction is to the left. On the other hand, the sliding door 520 opens and closes the front side of the game area GE, which corresponds to the prize-winning game machine 1 on the right side when viewed from the front. In this case, the sliding door 520 opens by sliding to the left when viewed from the front, and closes by sliding to the right. In other words, for the sliding door 520, the opening direction is to the left, and the closing direction is to the right. As described above, the sliding doors 510 and 520 have different opening directions. That is, the opening directions are opposite for sliding doors 510 and 520. Also, the sliding doors 510 and 520 have different closing directions. That is, the closing directions are opposite for sliding doors 510 and 520.

[0019] (Locking mechanism 600) As shown in Figures 28 and 30, the locking mechanism 600 comprises a latch lock body 610 located on the housing 10 and a latch receiving member 650 located on the sliding door 510. The latch lock body 610 is mounted on the inner surface of the housing 10. As shown in Figures 29 and 31, the latch lock body 610 comprises a base plate 611, a latch portion 620, a cylinder lock 630, and a link mechanism 640 that displaces the latch portion 620 in response to the operation of the cylinder lock 630. The base plate 611 is formed in a flat shape and is attached to the inner surface of the housing 10. The cylinder lock 630 comprises a cylinder 631 having a keyhole ke1 and a cam plate 632 driven by the cylinder 631. In the cylinder lock 630, with a dedicated key inserted into the keyhole ke1, the cam plate 632 can be rotated by rotating the key. The keyhole ke1 is located below the lower guide rail 530 on the front side of the housing 10. This allows the operator to insert a key into the keyhole ke1 from the outside of the housing 10. The cylinder 631 is positioned to extend along the depth direction. In the cylinder lock 630, the key inserted into the keyhole ke1 can be moved between the locked position and the unlocked position by rotating it around an axis that extends along the depth direction. When viewed from the front, the key inserted into the keyhole ke1 can be moved from the locked position to the unlocked position by rotating it to the right (clockwise). Conversely, when viewed from the front, the key inserted into the keyhole ke1 can be moved from the unlocked position to the locked position by rotating it to the left (counterclockwise). Furthermore, in the cylinder lock 630, the cam plate 632 can be rotated by rotating the key inserted into the keyhole ke1. In this case, when the key inserted into the keyhole ke1 is positioned in the locked position, the cam plate 632 is positioned in the locked position (see Figures 28 and 29). On the other hand, when the key inserted into the keyhole ke1 is positioned in the unlocked position, the cam plate 632 is positioned in the unlocked position (see Figures 30 and 31).

[0020] In this embodiment, the link mechanism 640 is composed of two link members (specifically, a first link member 641 and a second link member 642). The first link member 641 is formed in a roughly V-shape when viewed from the rear. A latch portion 620 is fixed to one end of the first link member 641. The latch portion 620 is formed in a rod shape and is provided to protrude upward from the upper surface of the link member 641. A bearing hole 641a is provided approximately in the center of the first link member 641. A rotating shaft 641b is provided on the back of the base plate 611. The rotating shaft 641b extends along the depth direction. The first link member 641 is attached to the base plate 611 by inserting the rotating shaft 641b through the bearing hole 641a. As a result, the first link member 641 can be displaced between a locked position (see Figures 28 and 29) and an unlocked position (see Figures 30 and 31) by rotating around the rotating shaft 641b. In this case, the first link member 641 can be displaced from the locked position to the unlocked position by rotating to the right (clockwise) when viewed from the back side. On the other hand, the first link member 641 can be displaced from the unlocked position to the locked position by rotating to the left (counterclockwise) when viewed from the back side. When the first link member 641 is positioned in the locked position, the latch portion 620 is positioned in the locked position (see Figures 28 and 29). Conversely, when the first link member 641 is positioned in the unlocked position, the latch portion 620 is positioned in the unlocked position (see Figures 30 and 31). The lower guide rail 530 is provided with a through hole 531. The latch portion 620 can be displaced between a locked position and an unlocked position via the through hole 531. Specifically, when the latch portion 620 is in the locked position, its tip protrudes upward from the lower guide rail 530 via the through hole 531. On the other hand, when the latch portion 620 is in the unlocked position, its tip retracts downward from the lower guide rail 530 via the through hole 531. In particular, the latch portion 620 in the locked position is displaced from the locked position to the unlocked position by tilting (falling) toward the closing direction of the sliding door 510 due to the action of the link mechanism 640. However, the latch portion 620 in the locked position is prevented from tilting (falling) toward the opening direction of the sliding door 510 due to the action of the link mechanism 640.

[0021] A guide hole 641c is provided at one end of the first link member 641 through which a rotating shaft 642b, described later, is inserted. Here, the link mechanism 640 is provided with a biasing means (a coil spring in this embodiment) SP1. The biasing means SP1 biases the first link member 641 toward the locked position. Specifically, one end of the biasing means SP1 is connected to the other end of the first link member 641. The other end of the biasing means SP1 is connected to the lower end of the base plate 611. The biasing means SP1 pulls the other end of the first link member 641 diagonally downward. As a result, the first link member 641 is biased toward the locked position by the biasing means SP1. In other words, the latch portion 620 is biased toward the locked position by the biasing means SP1. The second link member 642 is formed in a roughly U-shape when viewed from the rear. One end of the second link member 642 is connected to the end of the cam plate 632 via a rotating shaft 642a. The other end of the second link member 642 is provided with a rotating shaft 642b. The other end of the second link member 642 is connected to one end of the first link member 641 by inserting the rotating shaft 642b through a guide hole 641c. In this configuration, the rear side of the latch lock body 610 is open, exposing the latch portion 620, the cylinder lock 630, and the link mechanism 640. Specifically, the cylinder lock 630 is attached to the base plate 611 by a nut NT. The link mechanism 640 is configured to avoid the nut NT when viewed from the rear. This makes it easy to replace the cylinder lock 630.

[0022] As described above, in the locking mechanism 600, when the key inserted into the keyhole ke1 is positioned in the locked position, the cam plate 632 is positioned in the locked position. When the cam plate 632 is in the locked position, the first link member 641 can be displaced to either the locked or unlocked position. In other words, when the cam plate 632 is in the locked position, the latch portion 620 can be displaced to either the locked or unlocked position. In this case, when no force is applied to the latch portion 620, the biasing of the biasing means SP1 causes the first link member 641 to be positioned in the locked position, and consequently, the latch portion 620 is positioned in the locked position. On the other hand, when the key inserted into the keyhole ke1 is displaced from the locked position to the unlocked position, the cam plate 632 is displaced from the locked position to the unlocked position. When the cam plate 632 is displaced from the locked position to the unlocked position, the first link member 641 is displaced from the locked position to the unlocked position via the second link member 642. Then, when the first link member 641 is displaced from the locked position to the unlocked position, the latch portion 620 is displaced from the locked position to the unlocked position. In particular, when the key inserted into the keyhole ke1 is in the unlocked position, and consequently the latch portion 620 is also in the unlocked position, the link mechanism 640 allows the key to remain in the unlocked position, that is, the latch portion 620 remains in the unlocked position, even if the operator releases their hand from the key.

[0023] The latch receiving member 650 is located on the bottom surface of the sliding door 510. The latch receiving member 650 is located inside the frame 511 of the sliding door 510. The latch receiving member 650 is formed from resin in a flat plate shape. The latch receiving member 650 is composed of a buffer portion 651 and a latch hole 652. The buffer portion 651 is the part that contacts (collides with) the latch portion 620 when the sliding door 510 is slid in the closing direction. At this time, the impact when the latch portion 620 makes contact is mitigated because the buffer portion 651 is made of resin. The buffer portion 651 is provided so as to protrude from the side of the sliding door 510 toward the closing direction. In the buffer portion 651, a tapered surface is formed in the part that contacts the latch portion 620. The latch hole 652 is a hole into which the tip of the latch portion 620 is inserted. The latch hole 652 is provided on the bottom surface of the latch receiving member 650. That is, the latch hole 652 is provided on the bottom surface of the sliding door 510 (the surface facing the lower guide rail 530).

[0024] The locking mechanism 600 allows the sliding door 510 to be locked when the cam plate 632 is in the locked position and the tip of the latch portion 620, which is also in the locked position, is inserted into the latch hole 652. When the sliding door 510 is locked, the latch portion 620 in the locked position contacts the inner surface of the latch hole 652, preventing the sliding door 510 from sliding in the opening direction. In other words, as described above, the latch portion 620 in the locked position is prevented from tilting (falling) toward the opening direction of the sliding door 510 by the action of the link mechanism 640. As a result, even if the sliding door 510 (the inner surface of the latch hole 652) pushes the latch portion 620 toward the opening direction in an attempt to slide the sliding door 510 toward the opening direction, the latch portion 620 remains in the locked position, and the sliding door 510 remains locked. In the game area GE corresponding to the prize-winning game device 1 on the left, when arranging or moving prizes P, or configuring or changing the prize placement mechanism 30, first, a key is inserted into the keyhole ke1 of the locking mechanism 600 and the key is rotated from the locked position to the unlocked position. In this embodiment, when viewed from the front, the key can be moved from the locked position to the unlocked position by rotating it to the right (clockwise). When the key inserted in the keyhole ke1 is displaced from the locked position to the unlocked position, the latch part 620 is displaced from the locked position to the unlocked position. As a result, the latch part 620 is removed from the latch hole 652, and the sliding door 510 can be slid in the opening direction. Next, the sliding door 510 is slid in the opening direction. As a result, the front side of the game area GE corresponding to the prize-winning game device 1 on the left is opened, making it possible to arrange or move prizes P, configure or change the prize placement mechanism 30, etc. When locking the sliding door 510, first, the key is removed from the keyhole ke1. At this time, the key can be removed from the keyhole ke1 when it is in the locked position, but it cannot be removed when it is in the unlocked position. As a result, after the key is removed from the keyhole ke1, the latch portion 620 is positioned in the locked position by the biasing force of the biasing means SP1. Next, the sliding door 510 is slid in the closing direction. When the sliding door 510 is slid in the closing direction, the buffer portion 651 contacts (collides with) the latch portion 620 which is in the locked position, pushing the latch portion 620 in the locked position toward the closing direction. At this time, as described above, when the cam plate 632 is in the locked position, the latch portion 620 can be displaced from the locked position to the unlocked position by tilting (falling) toward the closing direction of the sliding door 510. As a result, when the sliding door 510 is slid in the closing direction, the latch portion 620, which has been pushed in by the sliding door 510 (cushion portion 651), tilts toward the closing direction of the sliding door 510 against the biasing force of the biasing means SP1, displacing it from the locked position toward the unlocked position, and the tip of the latch portion 620 slides under the sliding door 510. At this time, because the guide hole 641c is formed to a predetermined length, it is possible to displace the first link member 641 toward the unlocked position without displacing the second link member 642. Then, when the sliding door 510 is slid further in the closing direction, the biasing force of the biasing means SP1 causes the latch portion 620 to return to the locked position at the position of the latch hole 652 provided on the bottom surface of the sliding door 510, and the tip of the latch portion 620 is inserted into the latch hole 652. As a result, the sliding door 510 is locked. As described above, the locking mechanism 600 makes it possible to lock the sliding door 510 by sliding it in the closing direction. Therefore, locking the sliding door 510 does not require opening or closing a key, and the effort required to lock the sliding door 510 is reduced. In particular, if an operator opens the sliding door 510 and is performing tasks such as arranging and moving prizes P or configuring and changing the prize arrangement mechanism 30 in the game area GE corresponding to the prize winning game machine 1 on the left side, and receives a call from a customer, the sliding door 510 can be locked simply by closing it. Therefore, it is possible to prevent situations where the operator leaves the prize winning game machine 1 with the sliding door 510 unlocked.

[0025] (Locking mechanism 700) As shown in Figures 32 and 34, the locking mechanism 700 comprises a latch lock body 710 located on the housing 10 and a latch receiving member 750 located on the sliding door 520. The latch lock body 710 is mounted on the inner surface of the housing 10. As shown in Figures 33 and 35, the latch lock body 710 comprises a base plate 711, a latch portion 720, a cylinder lock 730, and a link mechanism 740 that displaces the latch portion 720 in response to the operation of the cylinder lock 730. The base plate 711 is formed in a flat shape and is attached to the inner surface of the housing 10. The cylinder lock 730 comprises a cylinder 731 having a keyhole ke2 and a cam plate 732 driven by the cylinder 731. In the cylinder lock 730, with a dedicated key inserted into the keyhole ke2, the cam plate 732 can be rotated by rotating the key. The keyhole ke2 is located below the lower guide rail 530 on the front side of the housing 10. This allows the operator to insert a key into the keyhole ke2 from the outside of the housing 10. The cylinder 731 is positioned to extend along the depth direction. In the cylinder lock 730, the key inserted into the keyhole ke2 can be moved between the locked position and the unlocked position by rotating it around an axis that extends along the depth direction. When viewed from the front, the key inserted into the keyhole ke2 can be moved from the locked position to the unlocked position by rotating it to the right (clockwise). Conversely, when viewed from the front, the key inserted into the keyhole ke2 can be moved from the unlocked position to the locked position by rotating it to the left (counterclockwise). Furthermore, in the cylinder lock 730, the cam plate 732 can be rotated by rotating the key inserted into the keyhole ke2. In this case, when the key inserted into the keyhole ke2 is positioned in the locked position, the cam plate 732 is positioned in the locked position (see Figures 32 and 33). On the other hand, when the key inserted into the keyhole ke2 is positioned in the unlocked position, the cam plate 732 is positioned in the unlocked position (see Figures 34 and 35).

[0026] In this embodiment, the link mechanism 740 is composed of two link members (specifically, a first link member 741 and a second link member 742), similar to the link mechanism 640. The first link member 741 is formed in a roughly U-shape when viewed from the rear. A latch portion 720 is fixed to one end of the first link member 741. The latch portion 720 is formed in a rod shape and is provided to protrude upward from the upper surface of the link member 741. A bearing hole 741a is provided approximately in the center of the first link member 741. A rotating shaft 741b is provided on the back of the base plate 711. The rotating shaft 741b extends along the depth direction. The first link member 741 is attached to the base plate 711 by inserting the rotating shaft 741b through the bearing hole 741a. As a result, the first link member 741 can be displaced between a locked position (see Figures 32 and 33) and an unlocked position (see Figures 34 and 35) by rotating around the rotating shaft 741b. In this case, the first link member 741 can be displaced from the locked position to the unlocked position by rotating it to the left (counterclockwise) when viewed from the back side. On the other hand, the first link member 741 can be displaced from the unlocked position to the locked position by rotating it to the right (clockwise) when viewed from the back side. When the first link member 741 is positioned in the locked position, the latch portion 720 is positioned in the locked position (see Figures 32 and 33). Conversely, when the first link member 741 is positioned in the unlocked position, the latch portion 720 is positioned in the unlocked position (see Figures 34 and 35). The lower guide rail 530 is provided with a through hole 532. The latch portion 720 can be displaced between a locked position and an unlocked position via the through hole 532. Specifically, when the latch portion 720 is in the locked position, the tip of the latch portion 720 protrudes upward toward the lower guide rail 530 via the through hole 532. On the other hand, when the latch portion 720 is in the unlocked position, the tip of the latch portion 720 is retracted downward toward the lower guide rail 530 via the through hole 532. In particular, the latch portion 720 in the locked position is displaced from the locked position to the unlocked position by tilting (falling) toward the closing direction of the sliding door 520 due to the action of the link mechanism 740. Note that the latch portion 720 in the locked position is prevented from tilting (falling) toward the opening direction of the sliding door 520 due to the action of the link mechanism 740.

[0027] A guide hole 741c is provided at one end of the first link member 741, through which a rotating shaft 742b, described later, is inserted. Here, the link mechanism 740 is provided with a biasing means (a coil spring in this embodiment) SP2. The biasing means SP2 biases the first link member 741 toward the locked position. Specifically, one end of the biasing means SP2 is connected to the other end of the first link member 741. The other end of the biasing means SP2 is connected to the lower end of the base plate 711. The biasing means SP2 pulls the other end of the first link member 741 diagonally downward. As a result, the first link member 741 is biased toward the locked position by the biasing means SP2. In other words, the latch portion 720 is biased toward the locked position by the biasing means SP2. The second link member 742 is formed in a roughly U-shape when viewed from the rear. One end of the second link member 742 is connected to the end of the cam plate 732 via a rotating shaft 742a. ​​The other end of the second link member 742 is provided with a rotating shaft 742b. The other end of the second link member 742 is connected to one end of the first link member 741 by inserting the rotating shaft 742b through a guide hole 741c. In this configuration, the rear side of the latch lock body 710 is open, exposing the latch portion 720, the cylinder lock 730, and the link mechanism 740. Specifically, the cylinder lock 730 is attached to the base plate 711 by a nut NT. The link mechanism 740 is configured to avoid the nut NT when viewed from the rear. This makes it easy to replace the cylinder lock 730.

[0028] As described above, in the locking mechanism 700, when the key inserted into the keyhole ke2 is positioned in the locked position, the cam plate 732 is positioned in the locked position. When the cam plate 732 is in the locked position, the first link member 741 can be displaced to either the locked or unlocked position. In other words, when the cam plate 732 is in the locked position, the latch portion 720 can be displaced to either the locked or unlocked position. In this case, when no force is applied to the latch portion 720, the biasing of the biasing means SP2 causes the first link member 741 to be positioned in the locked position, and consequently, the latch portion 720 is positioned in the locked position. On the other hand, when the key inserted into the keyhole ke2 is displaced from the locked position to the unlocked position, the cam plate 732 is displaced from the locked position to the unlocked position. When the cam plate 732 is displaced from the locked position to the unlocked position, the first link member 741 is displaced from the locked position to the unlocked position via the second link member 742. Then, when the first link member 741 is displaced from the locked position to the unlocked position, the latch portion 720 is displaced from the locked position to the unlocked position. In particular, when the key inserted into the keyhole ke2 is in the unlocked position, and consequently the latch portion 720 is also in the unlocked position, the link mechanism 740 allows the key to remain in the unlocked position, that is, the latch portion 720 remains in the unlocked position, even if the operator releases their hand from the key.

[0029] The latch receiving member 750 is located on the bottom surface of the sliding door 520. The latch receiving member 750 is located inside the frame 521 of the sliding door 520. The latch receiving member 750 is formed from resin in a flat plate shape. The latch receiving member 750 includes a buffer portion 751 and a latch hole 752. The buffer portion 751 is the part that contacts (collides with) the latch portion 720 when the sliding door 520 is slid in the closing direction. At this time, the impact when the latch portion 720 makes contact is mitigated because the buffer portion 751 is made of resin. The buffer portion 751 is provided so as to protrude from the side of the sliding door 520 toward the closing direction. In the buffer portion 751, a tapered surface is formed in the part that contacts the latch portion 720. The latch hole 752 is a hole into which the tip of the latch portion 720 is inserted. The latch hole 752 is provided on the bottom surface of the latch receiving member 750. That is, the latch hole 752 is provided on the bottom surface of the sliding door 520 (the surface facing the lower guide rail 530).

[0030] The locking mechanism 700 allows the sliding door 520 to be locked when the cam plate 732 is in the locked position and the tip of the latch portion 720, which is also in the locked position, is inserted into the latch hole 752. When the sliding door 520 is locked, the latch portion 720 in the locked position contacts the inner surface of the latch hole 752, preventing the sliding door 520 from sliding in the opening direction. In other words, as described above, the latch portion 720 in the locked position is prevented from tilting (falling) toward the opening direction of the sliding door 520 by the action of the link mechanism 740. As a result, even if the sliding door 520 (the inner surface of the latch hole 752) pushes the latch portion 720 toward the opening direction in an attempt to slide the sliding door 520 toward the opening direction, the latch portion 720 remains in the locked position, and the sliding door 520 remains locked. In the game area GE corresponding to the prize-winning game device 1 on the right, when arranging or moving prizes P, or configuring or changing the prize placement mechanism 30, first, a key is inserted into the keyhole ke2 of the locking mechanism 700 and the key is rotated from the locked position to the unlocked position. In this embodiment, similar to the locking mechanism 600, the key can be moved from the locked position to the unlocked position by rotating it to the right (clockwise) when viewed from the front. When the key inserted in the keyhole ke2 is displaced from the locked position to the unlocked position, the latch part 720 is displaced from the locked position to the unlocked position. As a result, the latch part 720 is removed from the latch hole 752, and the sliding door 520 can be slid in the opening direction. Next, the sliding door 520 is slid in the opening direction. As a result, the front side of the game area GE corresponding to the prize-winning game device 1 on the right is opened, making it possible to arrange or move prizes P, configure or change the prize placement mechanism 30, etc. When locking the sliding door 520, first, the key is removed from the keyhole ke2. At this time, the key can be removed from the keyhole ke2 when it is in the locked position, but it cannot be removed when it is in the unlocked position. As a result, after the key is removed from the keyhole ke2, the latch portion 720 is positioned in the locked position by the biasing force of the biasing means SP2. Next, the sliding door 520 is slid in the closing direction. When the sliding door 520 is slid in the closing direction, the buffer portion 751 contacts (collides with) the latch portion 720 which is in the locked position, pushing the latch portion 720 in the locked position toward the closing direction. At this time, as described above, when the cam plate 732 is in the locked position, the latch portion 720 can be displaced from the locked position to the unlocked position by tilting (falling) toward the closing direction of the sliding door 520. As a result, when the sliding door 520 is slid in the closing direction, the latch portion 720, which has been pushed in by the sliding door 520 (cushion portion 751), tilts toward the closing direction of the sliding door 520 against the biasing force of the biasing means SP2, displacing it from the locked position toward the unlocked position, and the tip of the latch portion 720 slides under the sliding door 520. At this time, because the guide hole 741c is formed to a predetermined length, it is possible to displace the first link member 741 toward the unlocked position without displacing the second link member 742. Then, when the sliding door 520 is slid further toward the closing direction, the biasing force of the biasing means SP2 causes the latch portion 720 to return to the locked position at the position of the latch hole 752 provided on the bottom surface of the sliding door 520, and the tip of the latch portion 720 is inserted into the latch hole 752. As a result, the sliding door 520 is locked. As described above, the locking mechanism 700 makes it possible to lock the sliding door 520 by sliding it in the closing direction. Therefore, locking the sliding door 520 does not require opening or closing a key, and the effort required to lock the sliding door 520 is reduced. In particular, if an operator opens the sliding door 520 and is performing tasks such as arranging and moving prizes P or configuring and changing the prize arrangement mechanism 30 in the game area GE corresponding to the prize winning game machine 1 on the right side, and receives a call from a customer, the sliding door 520 can be locked simply by closing it. Therefore, it is possible to prevent situations where the operator leaves the prize winning game machine 1 with the sliding door 520 unlocked.

[0031] In particular, the closing direction is reversed for sliding doors 510 and 520. Consequently, in locking mechanisms 600 and 700, when the latches 620 and 720 are displaced from the locked position to the unlocked position, the direction in which they tilt is reversed. However, in locking mechanisms 600 and 700, the direction in which the keys inserted into the keyholes ke1 and ke2 are turned to unlock the sliding doors 510 and 520 (hereinafter referred to as the "unlocking direction") is the same. That is, in locking mechanisms 600 and 700, the unlocking direction is to the right (clockwise) for both. This makes it possible for the operator to prevent misidentification of the unlocking direction for the locking mechanisms 600 and 700 corresponding to each sliding door 510 and 520.

[0032] (Base frame unit 20) Next, the configuration of the base frame unit 20 will be explained. Figure 2 is a perspective view showing the base frame unit 20 in its initial state. Figure 3 is a perspective view showing the base frame unit 20 in its first state. Figure 4 is a perspective view showing the base frame unit 20 in its second state. Here, in the initial state of the base frame unit 20 shown in Figure 2, the overall lifting frame 220 is positioned in its initial position (lowest position), and all individual lifting frames 231 to 236 are also positioned in their initial positions (lowest position). In the first state of the base frame unit 20 shown in Figure 3, the overall lifting frame 220 is positioned in its initial position, and each individual lifting frame 231 to 236 is positioned in a position raised from its initial position. In the second state of the base frame unit 20 shown in Figure 4, the overall lifting frame 220 is positioned in a position raised from its initial position, and each individual lifting frame 231 to 236 is also positioned in a position raised from its initial position. The base frame unit 20 is located inside the housing 10. As shown in Figures 2 to 4, the base frame unit 20 is composed of a foundation frame 210, an overall lifting frame 220 mounted to the foundation frame 210 so as to be movable up and down, and six sets of individual lifting frames 231 to 236 mounted to the overall lifting frame 220 so as to be movable up and down.

[0033] (Foundation frame 210) The foundation frame 210 is composed of four vertical members (columns) 211a to 211d and multiple horizontal members (beams and girders) spanning across the four vertical members 211a to 211d. The four vertical members 211a to 211d and the multiple horizontal members are each composed of rod-shaped members. Specifically, an upper horizontal member 212a, an intermediate horizontal member 212b, and a lower horizontal member 212c are spanned between the two vertical members 211a and 211c on the left side. The upper horizontal member 212a spans the upper ends of the two vertical members 211a and 211c. The intermediate horizontal member 212b spans the middle section between the two vertical members 211a and 211c. The lower horizontal member 212c spans the lower ends of the two vertical members 211a and 211c. Furthermore, an upper horizontal member 213a, an intermediate horizontal member 213b, and a lower horizontal member 213c are spanned between the two vertical members 211b and 211d on the right side. The upper horizontal member 213a spans the upper ends of the two vertical members 211b and 211d. The intermediate horizontal member 213b spans the middle section between the two vertical members 211b and 211d. The lower horizontal member 213c spans the lower ends of the two vertical members 211b and 211d. Furthermore, an upper horizontal member 214a and a lower horizontal member 214b are spanned between the two vertical members 211c and 211d at the rear. The upper horizontal member 214a spans the upper ends of the two vertical members 211c and 211d. The lower horizontal member 214b spans the lower ends of the two vertical members 211c and 211d. Furthermore, an upper horizontal member 215 is spanned between upper horizontal members 212a and 213a. The upper horizontal member 215 is spanned across the front ends of upper horizontal members 212a and 213a.

[0034] Furthermore, the base frame 210 is composed of a pair of left-side overall lifting guide rails 216a, 216b and a pair of right-side overall lifting guide rails 217a, 217b. Each left-side overall lifting guide rail 216a, 216b is composed of a flat plate-shaped member having a predetermined length. Each left-side overall lifting guide rail 216a, 216b is provided with a guide groove (guide rail) 216c. The guide groove 216c extends linearly along the longitudinal direction (the direction in which the left-side overall lifting guide rails 216a, 216b extend). Each of the left-side overall lifting guide rails 216a and 216b is spanned between the intermediate horizontal member 212b and the lower horizontal member 212c. As a result, each of the left-side overall lifting guide rails 216a and 216b is positioned so that the guide groove 216c extends along the vertical direction. Furthermore, the pair of left-side overall lifting guide rails 216a and 216b are positioned with a predetermined distance between them, with their guide grooves 216c facing each other. Each of the right-side overall lifting guide rails 217a and 217b is composed of a flat plate-shaped member having a predetermined length. Each of the right-side overall lifting guide rails 217a and 217b is provided with a guide groove (guide rail) 217c. The guide groove 217c extends linearly along the longitudinal direction (the direction in which the right-side overall lifting guide rails 217a and 217b extend). Each of the right-side overall lifting guide rails 217a and 217b is spanned between the intermediate horizontal member 213b and the lower horizontal member 213c. As a result, each of the right-side overall lifting guide rails 217a and 217b is positioned so that the guide groove 217c extends along the vertical direction. Furthermore, the pair of right-side overall lifting guide rails 217a and 217b are positioned with a predetermined distance between them, with their guide grooves 217c facing each other.

[0035] (Overall lifting frame 220) Figure 5 is an enlarged view showing the left frame unit 221. Here, Figure 5 shows the base frame unit 20 with the front left overall lifting guide rail 216a and the first individual lifting guide rail 227a omitted from the display. The overall lifting frame 220 is composed of a left frame unit 221, a right frame unit 222, and a connecting frame 223 that connects the left frame unit 221 and the right frame unit 222. The left frame unit 221 and the right frame unit 222 have a symmetrical configuration. The left frame unit 221 and the right frame unit 222 are each configured in a grid pattern. Specifically, the left frame unit 221 is composed of an upper frame 224a and a lower frame 225a, which are arranged in parallel. The left frame unit 221 is also composed of a pair of overall lifting sliders 226a and 226b, which are spanned between the upper frame 224a and the lower frame 225a, a first individual lifting guide rail 227a, a second individual lifting guide rail 228a, and a third individual lifting guide rail 229a. The right-side frame unit 222 comprises an upper frame 224b and a lower frame 225b, which are arranged in parallel. The right-side frame unit 222 also comprises a pair of overall lifting sliders 226c and 226d, which are spanned between the upper frame 224b and the lower frame 225b, as well as a first individual lifting guide rail 227b, a second individual lifting guide rail 228b, and a third individual lifting guide rail 229b. Each upper frame 224a, 224b is constructed from channel steel with a U-shaped cross-section. Each upper frame 224a, 224b is positioned with its open side facing downwards (with its back facing upwards) and extends along the depth direction. Three pairs (six in total) of guide holes gh are provided on the back of each upper frame 224a, 224b. The three pairs of guide holes gh are arranged at predetermined intervals along the depth direction. Each guide hole gh is a circular through-hole in plan view. Each of the lower frames 225a and 225b is constructed from angle steel with an L-shaped cross-section. The lower frames 225a and 225b are arranged parallel to the upper frames 224a and 224b and extend along the depth direction.

[0036] Each of the overall lifting sliders 226a, 226b, 226c, and 226d is constructed from channel steel with a U-shaped cross-section. The front overall lifting sliders 226a and 226c are positioned to extend vertically with their open surfaces facing the rear (with their backs facing the front). The upper ends of the front overall lifting sliders 226a and 226c are fixed to the front ends of the upper frames 224a and 224b, and the lower ends of the front overall lifting sliders 226a and 226c are fixed to the front ends of the lower frames 225a and 225b. On the other hand, the rear overall lifting sliders 226b and 226d are positioned to extend vertically with their open surfaces facing the front (with their backs facing the rear). The upper ends of the rear overall lifting sliders 226b and 226d are fixed to the rear ends of the upper frames 224a and 224b, and the lower ends of the rear overall lifting sliders 226b and 226d are fixed to the rear ends of the lower frames 225a and 225b. As shown in Figure 5, a pair of guide rollers gr are provided on the back of each of the overall lifting sliders 226a, 226b, 226c, and 226d. Note that the guide rollers gr provided on the rear overall lifting sliders 226b and 226d are not shown. The pair of guide rollers gr are provided at the lower ends of the overall lifting sliders 226a, 226b, 226c, and 226d, aligned at a predetermined interval along the vertical direction. Each guide roller gr is configured to rotate freely around a rotation axis (not shown) that extends along the depth direction. Furthermore, multiple locking holes rh (see Figure 5) are provided on the back of the front-side overall lifting sliders 226a and 226c. The multiple locking holes rh are located above the pair of guide rollers gr. The multiple locking holes rh are arranged at predetermined intervals along the vertical direction. Each locking hole rh is a circular through-hole.

[0037] Each individual lifting guide rail 227a, 227b, 228a, 228b, 229a, and 229b is constructed from channel steel with a U-shaped cross-section. Each first individual lifting guide rail 227a and 227b is positioned to extend vertically with its open side facing forward (with its back facing backward). Each second individual lifting guide rail 228a and 228b is positioned to extend vertically with its open side facing forward (with its back facing backward). Each third individual lifting guide rail 229a and 229b is positioned to extend vertically with its open side facing backward (with its back facing forward). The upper ends of each individual lifting guide rail 227a, 228a, and 229a are fixed to the upper frame 224a, and the lower ends of each individual lifting guide rail 227a, 228a, and 229a are fixed to the lower frame 225a. The first individual lifting guide rail 227a, the second individual lifting guide rail 228a, and the third individual lifting guide rail 229a are arranged in parallel. Furthermore, the first individual lifting guide rail 227a, the second individual lifting guide rail 228a, and the third individual lifting guide rail 229a are arranged at predetermined intervals along the depth direction. The upper ends of each individual lifting guide rail 227b, 228b, and 229b are fixed to the upper frame 224b, and the lower ends of each individual lifting guide rail 227b, 228b, and 229b are fixed to the lower frame 225b. The first individual lifting guide rail 227b, the second individual lifting guide rail 228b, and the third individual lifting guide rail 229b are arranged in parallel. Furthermore, the first individual lifting guide rail 227b, the second individual lifting guide rail 228b, and the third individual lifting guide rail 229b are arranged to be aligned at predetermined intervals along the depth direction. Each individual lifting guide rail 227a, 227b, 228a, 228b, 229a, and 229b has multiple locking holes RH (see Figure 5) on its back surface. The multiple locking holes RH are arranged at predetermined intervals along the vertical direction. Each locking hole RH is a circular through-hole.

[0038] The connecting frame 223 is made of channel steel (channel material) with a U-shaped cross-section. The connecting frame 223 is positioned to extend along the left-right direction with the open side facing forward (with the back side facing backward). The connecting frame 223 connects the left frame unit 221 and the right frame unit 222. Specifically, the left end of the connecting frame 223 is fixed to the rear end of the upper frame 224a. The right end of the connecting frame 223 is fixed to the rear end of the upper frame 224b. As a result, the overall lifting frame 220 is constructed by integrating the left frame unit 221 and the right frame unit 222 via a connecting frame 223.

[0039] The overall lifting frame 220 is attached to the foundation frame 210 so as to be able to move up and down. Specifically, the left frame unit 221 is supported (held) so as to be able to move up and down by a pair of left-side overall lifting guide rails 216a and 216b. That is, the two guide rollers gr of the front-side overall lifting slider 226a are positioned within the guide grooves 216c of the left-side overall lifting guide rail 216a. As a result, the front-side overall lifting slider 226a is able to slide vertically along the left-side overall lifting guide rail 216a (guide groove 216c). Furthermore, the two guide rollers gr of the rear overall lifting slider 226b are positioned within the guide grooves 216c of the left overall lifting guide rail 216b. This allows the rear overall lifting slider 226b to slide vertically along the left overall lifting guide rail 216b (guide groove 216c). Similarly, the right frame unit 222 is supported (held) so as to be able to move up and down by a pair of right-side overall lifting guide rails 217a and 217b. That is, the two guide rollers gr of the front-side overall lifting slider 226c are positioned within the guide grooves 217c of the right-side overall lifting guide rail 217a. This allows the front-side overall lifting slider 226c to slide vertically along the right-side overall lifting guide rail 217a (guide grooves 217c). Furthermore, the two guide rollers gr of the rear overall lifting slider 226d are positioned within the guide grooves 217c of the right overall lifting guide rail 217b. This allows the rear overall lifting slider 226d to slide vertically along the right overall lifting guide rail 217b (guide groove 217c). As described above, the overall lifting frame 220 is attached to the foundation frame 210 so that it can move up and down.

[0040] Here, the base frame 210 is configured to include a pair of overall lifting locking mechanisms 218 (a left overall lifting locking mechanism 218 and a right overall lifting locking mechanism 218). The pair of overall lifting locking mechanisms 218 make it possible to lock (fix) the lifting of the overall lifting frame 220 relative to the base frame 210. The left overall lifting lock mechanism 218 is located at the upper end of the left overall lifting guide rail 216a. The right overall lifting lock mechanism 218 is located at the upper end of the right overall lifting guide rail 217a. Note that the right overall lifting lock mechanism 218 is not shown. Each overall lifting locking mechanism 218 comprises an operating lever 218a and a locking shaft 218b. Each operating lever 218a can be operated (displaced) to a locked position or an unlocked position. Each locking shaft 218b is formed in a cylindrical shape and is arranged to extend along the depth direction. When each operating lever 218a is operated to the locked position, the locking shaft 218b protrudes toward the rear via a linkage mechanism (not shown). Conversely, when each operating lever 218a is operated to the unlocked position, the locking shaft 218b retracts toward the front via the linkage mechanism.

[0041] In the left-side overall lifting lock mechanism 218, when the operating lever 218a is operated to the locked position, the lock shaft 218b is inserted into one of the multiple lock holes rh provided in the front-side overall lifting slider 226a. This locks the sliding of the front-side overall lifting slider 226a relative to the left-side overall lifting guide rail 216a. Similarly, in the right-side overall lifting lock mechanism 218, when the operating lever 218a is operated to the locked position, the lock shaft 218b is inserted into one of the multiple lock holes rh provided in the front-side overall lifting slider 226c. This locks the sliding of the front-side overall lifting slider 226c relative to the right-side overall lifting guide rail 217a. This locks the overall lifting frame 220 relative to the base frame 210, making it impossible to move the overall lifting frame 220 relative to the base frame 210. In other words, the height of the overall lifting frame 220 is locked (fixed and maintained). In particular, each overall lifting slider 226a, 226c is provided with multiple locking holes rh along the vertical direction. As shown in Figures 2 and 4, this makes it possible to lock the overall lifting frame 220 at any height by selecting and changing the locking hole rh into which each locking shaft 218b is inserted. On the other hand, in the left-side overall lifting lock mechanism 218, when the operating lever 218a is moved to the release position, the lock shaft 218b is withdrawn from the lock hole rh provided in the front-side overall lifting slider 226a. This releases the lock of the front-side overall lifting slider 226a to the left-side overall lifting guide rail 216a. Similarly, in the right-side overall lifting lock mechanism 218, when the operating lever 218a is moved to the release position, the lock shaft 218b is withdrawn from the lock hole rh provided in the front-side overall lifting slider 226c. This releases the lock of the front-side overall lifting slider 226c to the right-side overall lifting guide rail 217a. This unlocks the overall lifting frame 220 relative to the foundation frame 210, allowing the overall lifting frame 220 to be raised and lowered relative to the foundation frame 210.

[0042] Furthermore, the foundation frame 210 is equipped with a pair of damper devices da that assist in the raising and lowering of the overall lifting frame 220 relative to the foundation frame 210. Each damper device da is composed of a twin-tube damper. In each damper device da, the tip of the piston rod is fixed to the lower horizontal members 212c and 213c, and the tip of the shell case is supported by the lower frame 225a and 225b via a link mechanism. This makes it possible for the operator to easily raise and lower the overall lifting frame 220. Specifically, the overall lifting frame 220 is pressed upward against the base frame 210 by a pair of damper devices da. As a result, when adjusting the height of the overall lifting frame 220, it is not necessary to lift the overall lifting frame 220 manually, and the overall lifting frame 220 can be raised or lowered by adjusting the force pressing down on the overall lifting frame 220 (the amount of body weight applied). Therefore, raising and lowering, maintaining the height, and locking the overall lifting frame 220 become easier. In particular, when the lock on the overall lifting frame 220 by the pair of overall lifting lock mechanisms 218 is released, it is possible to prevent the overall lifting frame 220 from falling suddenly.

[0043] (Individual lifting frames 231-236) Figure 6 is a cross-sectional view of the base frame 237. Here, Figure 6 shows a cross-section perpendicular to the longitudinal direction of the base frame 237 (the direction in which the base frame 237 extends). The six sets of individual lifting frames 231 to 236 have substantially the same configuration. Each individual lifting frame 231 to 236 is composed of a base frame 237, a pair of guide rods 238, and an individual lifting slider 238a. The base frame 237 is formed in the shape of a rectangular prism. The base frame 237 is positioned to extend along the depth direction. In the following description, of the four sides of the base frame 237, the upper side will be referred to as the "upper side," the lower side as the "lower side," and the inner side (game area GE side) as the "inner side." As shown in Figure 6, a T-groove tg is provided on at least the inner surface of the four sides of the base frame 237. In this embodiment, the T-groove tg is provided on the inner surface and the upper surface of the four sides of the base frame 237. In the example shown in Figure 6, a T-groove tg is provided on each of the four sides of the base frame 237. Each T-groove tg extends linearly along the longitudinal direction of the base frame 237 (the direction in which the base frame 237 extends). Each T-groove tg is provided from one end to the other in the longitudinal direction of the base frame 237. Each guide rod 238 is cylindrical in shape. Each guide rod 238 is provided so as to extend downward from the lower surface of the base frame 237. A pair of guide rods 238 are provided so as to be arranged at predetermined intervals along the longitudinal direction of the base frame 237. Each individual lifting slider 238a is constructed from a channel steel (channel material) with a U-shaped cross-section. Each individual lifting slider 238a is fixed to the lower end of one of the guide rods 238. Each individual lifting slider 238a is positioned to extend along the vertical direction. The width of each individual lifting slider 238a is narrower than the width of each individual lifting guide rail 227a, 227b, 228a, 228b, 229a, 229b.

[0044] In this embodiment, three sets of individual lifting frames 231 to 233 are attached to the left frame unit 221. The three sets of individual lifting frames 231 to 233 are arranged at predetermined intervals along the depth direction. Each of the individual lifting frames 231 to 233 is mounted to the left frame unit 221 so as to be able to move up and down. In particular, the three sets of individual lifting frames 231 to 233 are individually able to move up and down. Specifically, of the three sets of individual lifting frames 231 to 233, the front individual lifting frame 231 is supported (held) by the left frame unit 221 so that it can move up and down. That is, the individual lifting frame 231 is attached to the left frame unit 221 by inserting a pair of guide rods 238 through guide holes gh provided in the upper frame 224a, and by positioning an individual lifting slider 238a within the first individual lifting guide rail 227a. Each guide rod 238 is slidable vertically along the guide hole gh through which it is inserted. The individual lifting slider 238a is also slidable vertically along the first individual lifting guide rail 227a. As a result, the individual lifting frame 231 is able to move up and down relative to the left frame unit 221. In particular, the base frame 237 of the individual lifting frame 231 is movable up and down relative to the left frame unit 221. Furthermore, of the three sets of individual lifting frames 231 to 233, the middle individual lifting frame 232 is supported (held) by the left frame unit 221 so that it can move up and down. That is, the individual lifting frame 232 is attached to the left frame unit 221 by inserting a pair of guide rods 238 through guide holes gh provided in the upper frame 224a, and by positioning an individual lifting slider 238a within the second individual lifting guide rail 228a. Each guide rod 238 is slidable vertically along the guide hole gh through which it is inserted. The individual lifting slider 238a is also slidable vertically along the second individual lifting guide rail 228a. As a result, the individual lifting frame 232 is able to move up and down relative to the left frame unit 221. In particular, the base frame 237 of the individual lifting frame 232 is able to move up and down relative to the left frame unit 221. Furthermore, of the three sets of individual lifting frames 231-233, the rear individual lifting frame 233 is supported (held) by the left frame unit 221 so that it can move up and down. Specifically, the individual lifting frame 233 is attached to the left frame unit 221 by inserting a pair of guide rods 238 through guide holes gh provided in the upper frame 224a, and by positioning an individual lifting slider 238a within the third individual lifting guide rail 229a. Each guide rod 238 is slidable vertically along the guide hole gh through which it is inserted. The individual lifting slider 238a is also slidable vertically along the third individual lifting guide rail 229a. As a result, the individual lifting frame 233 is able to move up and down relative to the left frame unit 221. In particular, the base frame 237 of the individual lifting frame 233 is able to move up and down relative to the left frame unit 221.

[0045] Furthermore, three sets of individual lifting frames 234-236 are attached to the right frame unit 222. The three sets of individual lifting frames 234-236 are arranged at predetermined intervals along the depth direction. Each of the individual lifting frames 234-236 is mounted to the right frame unit 222 so as to be able to move up and down. In particular, the three sets of individual lifting frames 234-236 are individually movable up and down. Specifically, of the three sets of individual lifting frames 234-236, the front individual lifting frame 234 is supported (held) by the right frame unit 222 so that it can move up and down. That is, the individual lifting frame 234 is attached to the right frame unit 222 by inserting a pair of guide rods 238 through guide holes gh provided in the upper frame 224b, and by positioning an individual lifting slider 238a within the first individual lifting guide rail 227b. Each guide rod 238 is slidable vertically along the guide hole gh through which it is inserted. The individual lifting slider 238a is also slidable vertically along the first individual lifting guide rail 227b. As a result, the individual lifting frame 234 can move up and down relative to the right frame unit 222. In particular, the base frame 237 of the individual lifting frame 234 is movable up and down relative to the right frame unit 222. Furthermore, of the three sets of individual lifting frames 234-236, the middle individual lifting frame 235 is supported (held) by the right frame unit 222 so as to be able to move up and down. That is, the individual lifting frame 235 is attached to the right frame unit 222 by inserting a pair of guide rods 238 through guide holes gh provided in the upper frame 224b, and by positioning an individual lifting slider 238a within the second individual lifting guide rail 228b. Each guide rod 238 is slidable vertically along the guide hole gh through which it is inserted. The individual lifting slider 238a is also slidable vertically along the second individual lifting guide rail 228b. As a result, the individual lifting frame 235 is able to move up and down relative to the right frame unit 222. In particular, the base frame 237 of the individual lifting frame 235 is able to move up and down relative to the right frame unit 222. Furthermore, of the three sets of individual lifting frames 234-236, the rear individual lifting frame 236 is supported (held) by the right frame unit 222 so that it can move up and down. Specifically, the individual lifting frame 236 is attached to the right frame unit 222 by inserting a pair of guide rods 238 through guide holes gh provided in the upper frame 224b, and by positioning an individual lifting slider 238a within the third individual lifting guide rail 229b. Each guide rod 238 is slidable vertically along the guide hole gh through which it is inserted. The individual lifting slider 238a is also slidable vertically along the third individual lifting guide rail 229b. As a result, the individual lifting frame 236 is able to move up and down relative to the right frame unit 222. In particular, the base frame 237 of the individual lifting frame 236 is able to move up and down relative to the right frame unit 222. As described above, each individual lifting frame 231 to 236 is individually attached to the overall lifting frame 220 so that it can be raised and lowered.

[0046] Here, each individual lifting frame 231 to 236 is configured to include an individual lifting lock mechanism 239. The individual lifting lock mechanism 239 provided in each individual lifting frame 231 to 236 makes it possible to lock (fix and maintain) the lifting of the individual lifting frames 231 to 236 relative to the overall lifting frame 220. Each individual lifting lock mechanism 239 comprises an operation button 239a and a locking shaft 239b. The operation button 239a is mounted on the lower side of the base frame 237. The operation button 239a can be operated (displaced) to a locked position or an unlocked position. Specifically, the operation button 239a is pressurized by a compression spring or the like to be positioned in the locked position. Then, the operation button 239a can be operated from the locked position to the unlocked position by being pressed by an operator. The locking shaft 239b is attached to the individual lifting slider 238a. The locking shaft 239b is cylindrical in shape and is positioned to extend along the depth direction. When the operation button 239a is in the locked position, the locking shaft 239b protrudes outward from the back of the individual lifting slider 238a through a through hole provided in the individual lifting slider 238a. On the other hand, when the operation button 239a is operated to the release position, the locking shaft 239b retracts inward from the back of the individual lifting slider 238a.

[0047] In the individual lifting lock mechanism 239 provided in the individual lifting frame 231, when the operation button 239a is in the locked position, the lock shaft 239b is inserted into one of the multiple lock holes RH provided in the first individual lifting guide rail 227a. This locks the sliding of the individual lifting slider 238a relative to the first individual lifting guide rail 227a. This locks the individual lifting frame 231 relative to the overall lifting frame 220, making it impossible to move the individual lifting frame 231 relative to the overall lifting frame 220. In other words, the height of the individual lifting frame 231 is locked (fixed and maintained). In particular, the first individual lifting guide rail 227a is provided with multiple locking holes RH along the vertical direction. As shown in Figures 2 and 3, this makes it possible to lock the individual lifting frame 231 at any height by selecting and changing the locking hole RH into which the locking shaft 239b is inserted. On the other hand, in the individual lifting lock mechanism 239 provided in the individual lifting frame 231, when the operation button 239a is operated to the release position, the lock shaft 239b is withdrawn from the lock hole RH provided in the first individual lifting guide rail 227a. This releases the lock of the individual lifting slider 238a on the first individual lifting guide rail 227a. This unlocks the individual lifting frames 231 relative to the overall lifting frame 220, allowing the individual lifting frames 231 to move relative to the overall lifting frame 220.

[0048] Here, the other individual lifting frames 232-236 can also be raised and lowered, and locked at any desired height, using the same principle as the individual lifting frame 231. In this case, the individual lifting lock mechanism 239 provided in the individual lifting frame 232 locks the sliding of the individual lifting slider 238a relative to the second individual lifting guide rail 228a, thereby locking the lifting of the individual lifting frame 232 relative to the overall lifting frame 220. On the other hand, the individual lifting lock mechanism 239 provided by the individual lifting frame 233 locks the sliding of the individual lifting slider 238a relative to the third individual lifting guide rail 229a, thereby locking the lifting of the individual lifting frame 233 relative to the overall lifting frame 220. On the other hand, the individual lifting lock mechanism 239 provided in the individual lifting frame 234 locks the sliding of the individual lifting slider 238a relative to the first individual lifting guide rail 227b, thereby locking the lifting of the individual lifting frame 234 relative to the overall lifting frame 220. On the other hand, the individual lifting lock mechanism 239 provided in the individual lifting frame 235 locks the lifting of the individual lifting frame 235 relative to the overall lifting frame 220 by locking the sliding of the individual lifting slider 238a relative to the second individual lifting guide rail 228b. On the other hand, the individual lifting lock mechanism 239 provided by the individual lifting frame 236 locks the sliding of the individual lifting slider 238a relative to the third individual lifting guide rail 229b, thereby locking the lifting of the individual lifting frame 236 relative to the overall lifting frame 220.

[0049] (Prize distribution mechanism 30) Next, the configuration of the prize distribution mechanism 30 will be explained. Figure 7 is a perspective view showing an example of a prize placement mechanism 30 attached to the base frame unit 20. Inside the cabinet 10 (particularly within the area enclosed by the base frame unit 20), a game area GE is formed where prize-winning games are played. The prize placement mechanism 30 is a mechanism for placing prizes P within the game area GE. In other words, the prize placement mechanism 30 places the prizes P within the game area GE. Depending on the configuration of the prize placement mechanism 30, various placement methods such as placing, suspending, and clamping can be selected. In particular, in this embodiment, the prize placement mechanism 30 constitutes a prize placement area AE and an opening area OE within the game area GE. "Prize placement area AE" is the area where prize P will be placed. The "Opening Area OE" is an area where prize P can be obtained by dropping the prize P into it.

[0050] As shown in Figure 7, the prize placement mechanism 30 is attached to one or more of the six sets of individual lifting frames 231 to 236. In this case, the prize placement mechanism 30 is attached to the base frame 237. The prize placement mechanism 30 shown in Figure 7 is composed of a medium-sized floor frame 310B attached to the individual lifting frame 233, a floor panel 320 attached to the upper surface of the medium-sized floor frame 310B, and a flexible rod 340 stretched between the individual lifting frame 231 and the individual lifting frame 234. Here, the configuration of the prize distribution mechanism 30 shown in Figure 7 is just one example, and as will be described later, the prize distribution mechanism 30 can be configured in various ways. The prize placement mechanism 30 is constructed from a single component or by combining multiple components. In this embodiment, the prize placement mechanism 30 is composed of one or more small floor frames 310A, one or more medium-sized floor frames 310B, one or more large floor frames 310C, one or more floor panels 320, various floor parts, one or more flexible rods 340, etc. The prize placement mechanism 30 is constructed by combining one or more of these components. The following describes each component.

[0051] (Floor frame 310A, 310B, 310C) Figure 8 is a perspective view showing the medium-sized floor frame 310B. Figure 9 is a cross-sectional view along line AA shown in Figure 8. Figure 10 is a perspective view showing the small floor frame 310A and the medium-sized floor frame 310B connected together. The small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C have the same basic configuration. However, the small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C differ in size. Specifically, the long-side dimension (length) of the horizontal frame 311b, which will be described later, differs in the small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C. As shown in Figure 8, the floor frames 310A, 310B, and 310C are composed of a pair of vertical frames 311a, a pair of horizontal frames 311b, four corner brackets 312, and a plurality of fixing members (connecting members) 313. Each frame 311a and 311b is formed in the shape of a rectangular prism. In the following explanation, with the floor frames 310A, 310B, and 310C placed on a flat surface, the upper side of each frame 311a and 312b will be referred to as the "upper side," the lower side as the "lower side," the inner side (towards the center of the floor frames 310A, 310B, and 310C) as the "inner side," and the outer side (opposite the center of the floor frames 310A, 310B, and 310C) as the "outer side." Figures 8 and 9 show the state in which a T-slot nut (T-groove nut), described later, is inserted into the T-groove TG provided on the upper surface of each horizontal frame 311b. Therefore, when the T-slot nut (T-groove nut) is removed from each T-groove TG, that T-groove TG becomes the same state as the other T-groove TGs (such as the T-groove TGs provided on the upper surface of each vertical frame 311a). Here, the T-slot nut is a component used to attach the floor panel 320, various floor parts, etc. to each floor frame 310A, 310B, 310C. Figures 8 and 9 show an example in which a T-slot nut with dimensions approximately the same as the longitudinal dimension of the T-groove TG is used. However, it is possible to use various T-slot nuts with dimensions shorter than the longitudinal dimension of the T-groove TG. As shown in Figure 9, T-grooves TG are provided on at least the outer surface of each of the four sides of each frame 311a, 311b. In this embodiment, T-grooves TG are provided on the outer surface, the upper surface, and the lower surface of each of the four sides of each frame 311a, 311b. In the example shown in Figure 9, T-grooves TG are provided on each of the four sides of each frame 311a, 311b. Each T-groove TG extends linearly along the longitudinal direction of each frame 311a, 311b (the direction in which each frame 311a, 311b extends). Each T-groove TG is provided from one end to the other in the longitudinal direction of each frame 311a, 311b. Here, the configuration of each T-groove TG is identical to the configuration of each T-groove tg. That is, the shape of the cross-section perpendicular to the longitudinal direction of each T-groove TG is identical to the shape of the cross-section perpendicular to the longitudinal direction of each T-groove tg. In particular, the dimensions (opening width, bottom width, depth) of each T-groove TG are identical to the dimensions (opening width, bottom width, depth) of each T-groove tg.

[0052] Each corner bracket 312 is composed of a connector (not shown) and a resin cover (not shown) that covers the connector. The connector of each corner bracket 312 connects and fixes the vertical frame 311a and the horizontal frame 311b in a position approximately at a right angle. Each fixing member 313 is composed of a cylindrical shaft portion 313a, an operating portion 313b fixed to one end of the shaft portion 313a, and a T-slot nut portion 313c fixed to the other end of the shaft portion 313a. In each fixing member 313, the central axis of the shaft portion 313a, the central axis of the operating portion 313b, and the central axis of the T-slot nut portion 313c are arranged coaxially. This makes it possible to rotate the T-slot nut portion 313c via the shaft portion 313a by rotating the operating portion 313b. Here, the T-slot nut portion 313c is formed in a roughly rectangular plate shape when viewed from above. In particular, the longitudinal dimension (length) of the T-slot nut portion 313c is larger than the width of each T-slot TG,tg. On the other hand, the dimension (width) of the T-slot nut portion 313c in the direction perpendicular to the longitudinal direction is smaller than the width of each T-slot TG,tg.

[0053] Floor frames 310A, 310B, and 310C are constructed by connecting four frames 311a and 311b in an endless (ring-shaped) manner using four corner brackets 312. As a result, floor frames 310A, 310B, and 310C form a roughly rectangular frame (frame section) when viewed from above. Furthermore, one or more fixing members 313 are attached to each frame 311a, 311b. Specifically, each frame 311a, 311b is provided with a through hole h that penetrates between the bottom surface of a T-groove TG provided on the outer surface and the bottom surface of a T-groove TG provided on the inner surface. In this embodiment, one or more through holes h are provided in each frame 311a, 311b. And one fixing member 313 is attached to each through hole h. The shaft portion 313a of each fixing member 313 is inserted through the through hole h. Thus, the shaft portion 313a of each fixing member 313 penetrates the frames 311a and 311b via the T-groove TG provided on the inner surface, the through hole h, and the T-groove TG provided on the outer surface. The operating portion 313b of each fixing member 313 is positioned to protrude inward from the inner surface of the frames 311a and 311b. That is, the operating portion 313b of each fixing member 313 is positioned on the inside of the inner surface of the frames 311a and 311b. On the other hand, the T-groove nut portion 313c of each fixing member 313 is positioned to protrude outward from the outer surface of the frames 311a and 311b. That is, the T-groove nut portion 313c of each fixing member 313 is positioned on the outside of the outer surface of the frames 311a and 311b.

[0054] In the small floor frame 310A, medium floor frame 310B, and large floor frame 310C, the longitudinal dimensions (lengths) of the horizontal frames 311b differ, while the longitudinal dimensions (lengths) of the vertical frames 311a are the same. In the medium-sized floor frame 310B, the four frames 311a and 311b have the same dimensions in the longitudinal direction. As a result, the medium-sized floor frame 310B forms a roughly square frame when viewed from above. In the medium-sized floor frame 310B, two fixing members 313 are attached to each frame 311a and 311b. On the other hand, in the small floor frame 310A, the longitudinal dimension of the horizontal frame 311b is smaller than the longitudinal dimension of the vertical frame 311a. As a result, the small floor frame 310A has a vertically elongated, roughly rectangular frame when viewed from above. In particular, the width of the small floor frame 310A is half the width of the medium floor frame 310B. In the small floor frame 310A, two fixing members 313 are attached to each vertical frame 311a, and one fixing member 313 is attached to each horizontal frame 311b. On the other hand, in the large floor frame 310C, the longitudinal dimension of the horizontal frame 311b is larger than the longitudinal dimension of the vertical frame 311a. As a result, the large floor frame 310C becomes a roughly rectangular frame with a horizontal orientation when viewed from above. In particular, the width of the large floor frame 310C is three times the width of the medium floor frame 310B. In the large floor frame 310C, two fixing members 313 are attached to each frame 311a and 311b.

[0055] Each floor frame 310A, 310B, and 310C can be attached to the upper or inner surface of the base frame 237. Each floor frame 310A, 310B, and 310C can be attached to the upper or inner surface of the base frame 237 via a fixing member 313. In other words, when attaching floor frames 310A, 310B, and 310C to the upper or inner surface of the base frame 237, first, one of the four frames 311a and 311b that make up the floor frames 310A, 310B, and 310C (hereinafter referred to as the "fixed frame") is positioned so that its outer surface faces the upper or inner surface (hereinafter referred to as the "fixed surface") of the base frame 237. Next, the T-groove nut portion 313c of each fixing member 313 provided on the fixing frame is inserted into the T-groove tg provided on the fixing surface. At this time, by rotating the operating portion 313b of each fixing member 313 to align the longitudinal direction of the T-groove nut portion 313c with the longitudinal direction of the T-groove tg, it becomes possible to insert the T-groove nut portion 313c into the T-groove tg. Next, the operating portion 313b of each fixing member 313 is rotated to rotate the T-groove nut portion 313c by 90° in a predetermined direction. As a result, within the T-groove tg, the T-groove nut portion 313c is displaced from a state parallel to the T-groove tg (released state) to a state perpendicular to the T-groove tg (fixed state). Consequently, the T-groove nut portion 313c of each fixing member 313 is fixed within the T-groove tg. In this way, the fixing frame is fixed to the base frame 237 with the outer surface of the fixing frame and the fixing surface in close contact. In particular, when the T-groove nut portion 313c is displaced to a state perpendicular to the T-groove tg (fixed state), the position of the T-groove nut portion 313c within the T-groove tg is fixed. As a result, it becomes impossible to change the fixed position of the fixing member 313 in the T-groove tg. On the other hand, when the T-groove nut portion 313c is displaced to a state parallel to the T-groove tg (released state), the position of the T-groove nut portion 313c is released within the T-groove tg. This makes it possible to change the fixed position of the fixing member 313 in the T-groove tg. As described above, the floor frames 310A, 310B, and 310C are attached to the fixed surface of the base frame 237.

[0056] In particular, a T-groove tg is provided on the upper surface of the base frame 237, extending from one end to the other in the longitudinal direction. This makes it possible to fix the fixing member 313 at any position in the longitudinal direction on the upper surface of the base frame 237. Therefore, the fixing positions of the floor frames 310A, 310B, and 310C to the upper surface of the base frame 237 can be set arbitrarily. When the floor frames 310A, 310B, and 310C are attached to the upper surface of the base frame 237, they are positioned to extend upward from the upper surface of the base frame 237. In this case, the upper (or lower) surface of the floor frames 310A, 310B, and 310C will face the game area GE. Similarly, a T-groove tg is provided on the inner surface of the base frame 237, extending from one end to the other in the longitudinal direction. This makes it possible to fix the fixing member 313 at any position in the longitudinal direction on the inner surface of the base frame 237. Therefore, the fixing positions of the floor frames 310A, 310B, and 310C relative to the inner surface of the base frame 237 can be arbitrarily set. When the floor frames 310A, 310B, and 310C are attached to the inner surface of the base frame 237, they are positioned to extend from the inner surface of the base frame 237 toward the game area GE. In this case, the upper (or lower) surface of the floor frames 310A, 310B, and 310C will face upward.

[0057] As described above, for example, a floor frame 310A, 310B, or 310C can be attached to the upper or inner surface of a base frame 237. In this case, the fixing position of the floor frame 310A, 310B, or 310C can be adjusted along the longitudinal direction of the base frame 237. Furthermore, two floor frames 310A, 310B, and 310C can be attached to the upper or inner surface of one base frame 237. Furthermore, a single floor frame 310A, 310B, or 310C can be installed so as to span between two base frames 237. In this case, one of the two fixing members 313 provided on the fixed frame is fixed to the T-groove tg of one base frame 237, and the other fixing member 313 is fixed to the T-groove tg of the other base frame 237. This allows a single floor frame 310A, 310B, or 310C to be installed so as to span between the base frames 237 of two of the three sets of individual lifting frames 231 to 233 located on the left frame unit 221. Also, a single floor frame 310A, 310B, or 310C can be installed so as to span between the base frames 237 of two of the three sets of individual lifting frames 234 to 236 located on the right frame unit 222. In particular, by attaching a floor frame 310A, 310B, 310C so as to span between the base frames 237 of two of the three sets of individual lifting frames 231-233 arranged on the left frame unit 221, and then changing (adjusting) the relative positional relationship (height relationship) of the base frames 237 of the two sets of individual lifting frames, it becomes possible to arbitrarily change (adjust) the angle of the floor frame 310A, 310B, 310C. In this embodiment, while keeping each T-groove nut portion 313c in a state perpendicular to the T-groove tg (fixed state), it is possible to arbitrarily change the angle of the floor frame 310A, 310B, 310C by changing the relative positional relationship of the base frames 237 of the two sets of individual lifting frames. Similarly, by attaching a floor frame 310A, 310B, 310C so as to span between the base frames 237 of two of the three sets of individual lifting frames 234-236 arranged on the right frame unit 222, and then changing (adjusting) the relative positional relationship (height relationship) of the base frames 237 of the two sets of individual lifting frames, it becomes possible to arbitrarily change (adjust) the angle of the floor frame 310A, 310B, 310C. In this embodiment, while keeping each T-groove nut portion 313c in a state perpendicular to the T-groove tg (fixed state), it is possible to arbitrarily change the angle of the floor frame 310A, 310B, 310C by changing the relative positional relationship of the base frames 237 of the two sets of individual lifting frames.

[0058] Furthermore, each floor frame 310A, 310B, and 310C can be attached to other floor frames 310A, 310B, and 310C via a fixing member 313. This makes it possible to connect multiple floor frames 310A, 310B, and 310C. In this case, it is possible to connect multiple floor frames 310A, 310B, and 310C of any size. In other words, when attaching the first floor frames 310A, 310B, 310C to the second floor frames 310A, 310B, 310C, first, the outer surface of one of the four frames 311a, 311b constituting the first floor frames 310A, 310B, 310C (hereinafter referred to as the "first fixed frame") is positioned facing the upper or outer surface (hereinafter referred to as the "fixed surface") of one of the four frames 311a, 311b constituting the second floor frames 310A, 310B, 310C (hereinafter referred to as the "second fixed frame"). Next, the T-groove nut portion 313c of each fixing member 313 provided on the first fixing frame is inserted into the T-groove TG provided on the fixing surface. At this time, by rotating the operating portion 313b of each fixing member 313 to align the longitudinal direction of the T-groove nut portion 313c with the longitudinal direction of the T-groove TG, it becomes possible to insert the T-groove nut portion 313c into the T-groove TG. Next, the operating portion 313b of each fixing member 313 is rotated to rotate the T-groove nut portion 313c by 90° in a predetermined direction. As a result, within the T-groove TG, the T-groove nut portion 313c is displaced from a state parallel to the T-groove TG (released state) to a state perpendicular to the T-groove TG (fixed state). Consequently, the T-groove nut portion 313c of each fixing member 313 is fixed within the T-groove TG. In this way, the first fixing frame is fixed to the second fixing frame with the outer surface of the first fixing frame and the fixing surface of the second fixing frame in close contact. In particular, when the T-groove nut portion 313c is displaced to a state perpendicular to the T-groove TG (fixed state), the position of the T-groove nut portion 313c within the T-groove TG is fixed. As a result, it becomes impossible to change the fixed position of the fixing member 313 in the T-groove TG. On the other hand, when the T-groove nut portion 313c is displaced to a state parallel to the T-groove TG (released state), the position of the T-groove nut portion 313c is released within the T-groove TG. This makes it possible to change the fixed position of the fixing member 313 in the T-groove TG. Here, when the T-groove nut portion 313c is displaced to be parallel to the T-groove TG (released state), it is possible to slide the first fixing frame relative to the second fixing frame while the T-groove nut portion 313c remains inserted into the T-groove TG. This makes it possible to change (adjust) the fixing position of the first fixing frame relative to the second fixing frame without removing the T-groove nut portion 313c from the T-groove TG. Furthermore, by setting one of the pair of T-groove nut portions 313c to be perpendicular to the T-groove TG (fixed state) and the other T-groove nut portion 313c to be parallel to the T-groove TG (released state), it becomes possible to rotate the first fixed frame relative to the second fixed frame using one of the T-groove nut portions 313c (fixed member 313) as an axis. As described above, the first floor frames 310A, 310B, and 310C are attached to the fixed surfaces of the second floor frames 310A, 310B, and 310C.

[0059] In particular, a T-groove TG is provided on the upper surface of each frame 311a, 311b, extending from one end to the other in the longitudinal direction. This makes it possible to fix the fixing member 313 (fixing member 313 of the first fixing frame) at any position in the longitudinal direction on the upper surface of each frame 311a, 311b (second fixing frame). Therefore, the fixing positions of the first floor frames 310A, 310B, 310C to the upper surface of the second fixing frame can be set arbitrarily. When the first floor frames 310A, 310B, 310C are attached to the upper surface of the second fixing frame, the first floor frames 310A, 310B, 310C are arranged to extend upward from the upper surface of the second fixing frame. In this configuration, the upper surfaces of the first floor frames 310A, 310B, and 310C, and the upper surfaces of the second floor frames 310A, 310B, and 310C are arranged to intersect. Similarly, each frame 311a, 311b has an outer surface provided with a T-groove TG extending from one end to the other in the longitudinal direction. This makes it possible to fix the fixing member 313 (fixing member 313 of the first fixing frame) at any position in the longitudinal direction on the outer surface of each frame 311a, 311b (second fixing frame). Therefore, the fixing positions of the first floor frames 310A, 310B, 310C to the outer surface of the second fixing frame can be set arbitrarily. When the first floor frames 310A, 310B, 310C are attached to the outer surface of the second fixing frame, the first floor frames 310A, 310B, 310C are arranged to extend outward from the outer surface of the second fixing frame. In this case, the upper surfaces of the first floor frames 310A, 310B, and 310C, and the upper surfaces of the second floor frames 310A, 310B, and 310C are arranged on the same plane.

[0060] As described above, for example, a floor frame 310A, 310B, 310C (first fixed frame) can be attached to the upper or outer surface of a frame 311a, 311b (second fixed frame). In this case, the fixing position of the floor frame 310A, 310B, 310C (first fixed frame) can be adjusted along the longitudinal direction of the frame 311a, 311b (second fixed frame). Furthermore, two floor frames 310A, 310B, and 310C (first fixed frames) can be attached to the upper or outer surface of one frame 311a, 311b (second fixed frame). In this case, the fixing member 313 provided on one first fixed frame and the fixing member 313 provided on the other first fixed frame are fixed to the T-groove TG (the same T-groove TG) provided on the second fixed frame. For example, as shown in Figure 10, two small floor frames 310A can be attached to the outer surface of the horizontal frame 311b of one medium-sized floor frame 310B. Furthermore, a floor frame 310A, 310B, 310C (first fixed frame) can be attached so as to span between the upper or outer surfaces of two frames 311a, 311b (second fixed frame). In this case, one of the two fixing members 313 provided on the first fixed frame is fixed to the T-groove TG of the second fixed frame of one floor frame 310A, 310B, 310C, and the other fixing member 313 is fixed to the T-groove TG of the second fixed frame of the other floor frame 310A, 310B, 310C. Furthermore, it is also possible to attach a frame member of the type that is fixed by screw fastening as described in Patent Document 1 (hereinafter referred to as the "old type frame member") to the floor frames 310A, 310B, and 310C. To do this, a T-slot nut (T-slot nut) is inserted into a T-slot TG provided on the upper or outer surface (fixing surface) of any of the four frames 311a, 311b that make up the floor frames 310A, 310B, and 310C. Then, a screw inserted through a screw hole provided on one side of the old type frame member is fitted into a screw hole provided in the T-slot nut inserted into the T-slot TG on the fixing surface. This makes it possible to connect the floor frames 310A, 310B, 310C and the old type frame member.

[0061] (Floor frame 810) Next, a floor frame 810 relating to a modified version of floor frames 310A, 310B, and 310C will be described. Figure 36 is a perspective view showing the floor frame 810. Figure 37 is a perspective view showing the fixing member 820. Figure 38 is a perspective view showing how two floor frames 810 are connected to each other. In this embodiment, floor frames 310A, 310B, and 310C are used as components of the prize placement mechanism 30. However, a floor frame 810 may be used instead of floor frames 310A, 310B, and 310C as components of the prize placement mechanism 30. As shown in Figure 36, the floor frame 810 has a shape in which four frames 811 are connected in an endless (ring-shaped) manner. As a result, the floor frame 810 becomes a roughly rectangular frame (frame part) when viewed from above. The floor frame 810 is formed by overlapping an upper part that is formed in an endless, roughly rectangular shape with a lower part that is also formed in an endless, roughly rectangular shape. Each frame 811 is formed in the shape of a rectangular prism. In the following explanation, with the floor frame 810 placed on a flat surface, of the four sides of each frame 811, the upper side will be referred to as the "upper side," the lower side as the "lower side," the inner side (towards the center of the floor frame 810) as the "inner side," and the outer side (opposite the center of the floor frame 810) as the "outer side." Each frame 811 has a T-groove TGR on its outer surface. Each T-groove TGR extends linearly along the longitudinal direction of each frame 811 (the direction in which each frame 811 extends). Each T-groove TGR extends from one end to the other in the longitudinal direction of each frame 811. Here, the configuration of each T-groove TGR is identical to the configuration of each T-groove tg. That is, the shape of the cross-section perpendicular to the longitudinal direction of each T-groove TGR is identical to the shape of the cross-section perpendicular to the longitudinal direction of each T-groove tg. In particular, the dimensions (opening width, bottom width, depth) of each T-groove TGR are identical to the dimensions (opening width, bottom width, depth) of each T-groove tg. Each frame 811 is provided with a through hole ha that penetrates between the bottom surface of the T-groove TGR on the outer surface and the inner surface. In this embodiment, each frame 811 is provided with two through holes ha. The shaft portion 821 of the fixing member 820, which will be described later, can be inserted through each through hole ha. The floor panel 320, which will be described later, can be attached to the top surface of the floor frame 810.

[0062] As shown in Figure 37, the fixing member 820 is composed of a cylindrical shaft portion 821, an operating portion 822 fixed to one end of the shaft portion 821, a T-slot nut portion (T-slot nut portion) 823 fixed to the other end of the shaft portion 821, and a fixing nut 824 screwed onto the shaft portion 821. In the fixing member 820, the central axis of the shaft portion 821, the central axis of the operating portion 822, the central axis of the fixing nut 824, and the central axis of the T-groove nut portion 823 are arranged coaxially. This makes it possible to rotate the T-groove nut portion 823 via the shaft portion 821 by rotating the operating portion 822. The T-slot nut portion 823 is formed in a roughly rectangular plate shape when viewed from above. In particular, the longitudinal dimension (length) of the T-slot nut portion 823 is greater than the width of each T-slot TGR,tg. On the other hand, the dimension (width) of the T-slot nut portion 823 in the direction perpendicular to the longitudinal direction is smaller than the width of each T-slot TGR,tg. The fixing nut 824 has a through hole (not shown) through which the shaft portion 821 is inserted. A screw groove is provided on the inner circumferential surface of the through hole. The outer circumferential surface of the shaft portion 821 is provided with screw threads that engage with the screw grooves provided on the inner circumferential surface of the through hole of the fixing nut 824. The screw threads are provided in a predetermined range at one end of the shaft portion 821. The fixing nut 824 is then screwed into the screw threads provided on the outer circumferential surface of the shaft portion 821. As a result, the fixing nut 824 can be moved along the shaft portion 821 by rotating it around the shaft portion 821. In this case, the fixing nut 824 can be moved between the T-groove nut portion 823 and the operating portion 822. Specifically, the fixing nut 824 can be moved toward the T-groove nut portion 823 by rotating it clockwise around the shaft portion 821. On the other hand, the fixing nut 824 can be moved toward the operating part 822 by rotating it counterclockwise around the shaft part 821. As described above, the fixing member 820 makes it possible to change the distance between the fixing nut 824 and the T-groove nut part 823 by moving (rotating) the fixing nut 824.

[0063] The floor frame 810 can be attached to other floor frames 810 via a fixing member 820. This makes it possible to connect multiple floor frames 810. As shown in Figure 38, when attaching the first floor frame 810 to the second floor frame 810, first, the outer surface of one of the four frames 811 constituting the first floor frame 810 (hereinafter referred to as the "first fixed frame") is positioned facing the outer surface (hereinafter referred to as the "fixed surface") of one of the four frames 811 constituting the second floor frame 810 (hereinafter referred to as the "second fixed frame"). Next, the shaft portion 821 of the fixing member 820 is inserted through the through hole ha provided in the first fixing frame. At this time, the tip of the shaft portion 821 on the T-groove nut portion 823 side is inserted from the inner side to the outer side of the through hole ha. As a result, the T-groove nut portion 823 of the fixing member 820 protrudes outward from the first fixing frame through the T-groove TGR of the first fixing frame. Next, the T-groove nut portion 823 of the fixing member 820, which protrudes outward from the first fixing frame, is inserted into the T-groove TGR provided on the fixing surface. At this time, by rotating the operating portion 822 of the fixing member 820 to align the longitudinal direction of the T-groove nut portion 823 with the longitudinal direction of the T-groove TGR, it becomes possible to insert the T-groove nut portion 823 into the T-groove TGR. Next, the operating part 822 of the fixing member 820 is rotated to rotate the T-groove nut portion 823 by 90° in a predetermined direction. As a result, within the T-groove TGR, the T-groove nut portion 823 is displaced from a state parallel to the T-groove TGR (released state) to a state perpendicular to the T-groove TGR (fixed state). Next, the fixing nut 824 of the fixing member 820 is rotated clockwise and moved toward the T-groove nut portion 823, thereby sandwiching the outer surface and fixing surface of the first fixing frame between the T-groove nut portion 823 and the fixing nut 824. As a result, the first fixing frame is fixed to the second fixing frame with the outer surface and fixing surface of the first fixing frame in close contact. As described above, the first floor frame 810 is attached to the fixed surface of the second floor frame 810. In this embodiment, a hole 811a communicating with the T-groove TGR is provided on the upper surface of each frame 811. In each frame 811, a T-groove nut (T-slot nut) can be inserted into the T-groove TGR through the hole 811a. This makes it possible to fix the first fixing frame to the second fixing frame by using a bolt (screw) instead of a fixing member 820. To do this, first, a T-groove nut (T-slot nut) is inserted into the T-groove TGR of the second fixing frame. Next, a bolt (screw) is inserted through the through hole ha of the first fixing frame. At this time, the tip of the bolt is inserted from the inner side to the outer side of the through hole ha. This causes the tip of the bolt to protrude outwards from the first fixing frame through the T-groove TGR of the first fixing frame. Next, the tip of the bolt protruding outwards from the first fixing frame is fitted into the screw hole provided in the T-groove nut inserted into the T-groove TGR of the second fixing frame. This fixes the first fixed frame to the second fixed frame. Furthermore, it is also possible to attach a frame member of the type that is fixed by screw fastening as described in Patent Document 1 (hereinafter referred to as the "old type frame member") to the floor frame 810. To do this, a T-slot nut is inserted into the T-slot TGR of one of the four frames 811 that make up the floor frame 810. Then, a screw inserted through a screw hole provided on the side of one side of the old type frame member is fitted into the screw hole provided in the T-slot nut inserted into the T-slot TGR of the frame 811. This makes it possible to connect the floor frame 810 and the old type frame member.

[0064] Similarly, the floor frame 810 can be attached to the upper or inner surface of the base frame 237 via the fixing member 820. When attaching the floor frame 810 to the upper or inner surface of the base frame 237, first, one of the four frames 811 constituting the floor frame 810 (hereinafter referred to as the "fixed frame") is positioned so that its outer surface faces the upper or inner surface (hereinafter referred to as the "fixed surface") of the base frame 237. Next, the shaft portion 821 of the fixing member 820 is inserted through the through hole ha provided in the fixing frame. At this time, the tip of the shaft portion 821 on the T-groove nut portion 823 side is inserted from the inner side to the outer side of the through hole ha. As a result, the T-groove nut portion 823 of the fixing member 820 protrudes outward from the fixing frame via the T-groove TGR of the fixing frame. Next, the T-groove nut portion 823 of the fixing member 820, which protrudes outward from the fixing frame, is inserted into the T-groove tg provided on the fixing surface. At this time, by rotating the operating portion 822 of the fixing member 820 to align the longitudinal direction of the T-groove nut portion 823 with the longitudinal direction of the T-groove tg, it becomes possible to insert the T-groove nut portion 823 into the T-groove tg. Next, the operating part 822 of the fixing member 820 is rotated to rotate the T-groove nut portion 823 by 90° in a predetermined direction. As a result, within the T-groove tg, the T-groove nut portion 823 is displaced from a state parallel to the T-groove tg (released state) to a state perpendicular to the T-groove tg (fixed state). Next, the fixing nut 824 of the fixing member 820 is rotated clockwise and moved toward the T-groove nut portion 823, thereby sandwiching the outer surface and fixing surface of the fixing frame between the T-groove nut portion 823 and the fixing nut 824. As a result, the fixing frame is fixed to the base frame 237 with the outer surface and fixing surface of the fixing frame in close contact. As described above, the floor frame 810 is attached to the fixed surface of the base frame 237.

[0065] (Floor panel 320) Figure 11 is a perspective view showing the floor panel 320. Figure 11 shows the floor panel 320 attached to the upper surface of the medium-sized floor frame 310B. As shown in Figure 11, the floor panel 320 is formed in a roughly square, flat shape when viewed from above. The length and width of the floor panel 320 are the same as the length and width of the medium-sized floor frame 310B. Multiple mounting sections (fixing sections) 321 are provided on the upper surface of the floor panel 320. Various floor parts can be attached to each mounting section 321. Multiple mounting parts 321 are arranged regularly in a predetermined pattern on the upper surface of the floor panel 320. Specifically, the multiple mounting parts 321 are arranged in a matrix (row and column) on the upper surface of the floor panel 320. In this embodiment, 36 mounting parts 321 are arranged in 6 rows and 6 columns on the upper surface of the floor panel 320. The six mounting parts 321 constituting each row are arranged at equal intervals. Similarly, the six mounting parts 321 constituting each column are arranged at equal intervals. Furthermore, the spacing between two adjacent mounting parts 321 in each row (hereinafter referred to as "column spacing") and the spacing between two adjacent mounting parts 321 in each column (hereinafter referred to as "row spacing") are the same. In particular, row spacing and column spacing can be set according to the intended gameplay. For example, if floor parts are attached to two adjacent mounting parts 321 in each row or column, and the game involves using a claw member 411a (described later) to pass between the floor parts attached to the two mounting parts 321 to approach the prize P, then the row spacing and column spacing are set to be less than the dimensions of the prize P and greater than or equal to the width of the claw member 411a. In this case, the narrower the row spacing and column spacing, the more difficult it becomes to access the prize P, increasing the difficulty of the prize-winning game. On the other hand, the wider the row spacing and column spacing, the easier it becomes to access the prize P, decreasing the difficulty of the prize-winning game. Alternatively, if floor parts are attached to two adjacent mounting parts 321 in each row or column, and the claw member 411a described later is prevented from passing between the floor parts attached to the two mounting parts 321, thereby creating a game that only allows a direct approach to the prize P, the row spacing and column spacing are set to be less than the dimensions of the prize P and less than the width of the claw member 411a. This makes it possible to improve the difficulty of the prize acquisition game by preventing (making impossible) the claw member 411a from passing between the floor parts attached to the two mounting parts 321 when floor parts are attached to two adjacent mounting parts 321 in each row or column. In this embodiment, multiple claw members 411a with different widths are provided. The row spacing and column spacing are set to be narrower than the width of the widest claw member 411a, and wider than the width of the narrowest claw member 411a. Furthermore, twice the row spacing and twice the column spacing are set to be wider than the width of the widest claw member 411a. As a result, when floor parts are attached to two adjacent mounting parts 321 in each row or column, the passage of the widest claw member 411a between the two floor parts attached to the mounting parts 321 is prevented (made impossible), while the passage of the narrowest claw member 411a between the two floor parts attached to the mounting parts 321 is permitted (made possible). On the other hand, if floor parts are attached to two mounting parts 321 with one mounting part 321 open in each row or column, the widest claw member 411a is allowed (makes possible) to pass between the floor parts attached to the two mounting parts 321. In this embodiment, the multiple mounting parts 321 are arranged in a matrix on the upper surface of the floor panel 320, with the multiple mounting parts 321 constituting each row and column being arranged at equal intervals. However, the multiple mounting parts 321 on the upper surface of the floor panel 320 may be arranged according to other rules. Furthermore, the multiple mounting parts 321 constituting each row and column do not necessarily have to be arranged at equal intervals. For example, multiple mounting parts 321 may be arranged radially on the upper surface of the floor panel 320. Alternatively, the multiple mounting parts 321 may be arranged concentrically on the upper surface of the floor panel 320. In this case, the spacing between the multiple mounting parts 321 constituting the outer circle and the spacing between the multiple mounting parts 321 constituting the inner circle may be different. For example, the spacing between the multiple mounting parts 321 constituting the outer circle may be set wider than the spacing between the multiple mounting parts 321 constituting the inner circle. In particular, the spacing between the multiple mounting parts 321 constituting the outer circle may be set wider. This makes it possible to make it more difficult for the claw member 411a to pass between the multiple floor parts constituting the inner circle, when floor parts are attached to each of the multiple mounting parts 321 constituting each circle, and the claw member 411a can hold the prize P more firmly as it passes between the multiple floor parts constituting the inner circle. Alternatively, the spacing between the multiple mounting parts 321 constituting the outer circle may be set narrower than the spacing between the multiple mounting parts 321 constituting the inner circle. In particular, the spacing between the multiple mounting parts 321 that make up the outer circle is set to be narrower. This makes it possible to make it more difficult for the prize P to pass between the multiple floor parts that make up the outer circle, when floor parts are attached to each of the multiple mounting parts 321 that make up each circle, and the prize P is scraped out from the center of the floor panel 320 by the claw member 411a.

[0066] Each mounting portion 321 is constructed by fitting a hexagonal nut into a recess (hole) provided on the upper surface of the floor panel 320. Alternatively, a cylindrical member made of an elastic material such as resin or rubber may be used instead of the hexagonal nut. In particular, the upper surface of each mounting portion 321 (hexagonal nut) is lower than the upper surface of the floor panel 320. That is, the upper surface of each mounting portion 321 is recessed (recessed, embedded, or indented) relative to the upper surface of the floor panel 320. This makes it possible to prevent the claw member 411a from catching on each mounting portion 321. Furthermore, the upper surfaces of each mounting portion 321 (hexagonal nut) may be arranged to be on the same plane as the upper surface of the floor panel 320. Even in such a configuration, it is possible to prevent the claw members 411a from catching on each mounting portion 321.

[0067] The floor panel 320 can be attached to the top (or bottom) surface of the floor frames 310A, 310B, and 310C. In this case, when attaching a floor panel 320 to the upper surface of a small floor frame 310A, two small floor frames 310A can be connected, and one floor panel 320 can be attached to the upper surface of the two connected small floor frames 310A. On the other hand, one floor panel 320 can be attached to the top surface of the medium-sized floor frame 310B. On the other hand, it is possible to mount three floor panels 320 side by side on the top surface of the large floor frame 310C. In particular, by connecting multiple floor frames 310A, 310B, and 310C, it is possible to install multiple floor panels 320 side by side on the upper surface of the connected multiple floor frames 310A, 310B, and 310C. In this configuration, the column spacing and row spacing are made the same for two adjacent floor panels 320. In this embodiment, only a floor panel 320 corresponding to the medium-sized floor frame 310B is provided. However, it is also possible to have a configuration in which floor panels 320 corresponding to the small floor frame 310A, floor panels 320 corresponding to the medium-sized floor frame 310B, and floor panels 320 corresponding to the large floor frame 310C are provided. Specifically, the length and width of the floor panel 320 corresponding to the small floor frame 310A are made the same as the length and width of the small floor frame 310A. Similarly, the length and width of the floor panel 320 corresponding to the medium-sized floor frame 310B are made the same as the length and width of the medium-sized floor frame 310B. Furthermore, the length and width of the floor panel 320 corresponding to the large floor frame 310C are made the same as the length and width of the large floor frame 310C. This makes it possible to attach one floor panel 320 (a floor panel 320 corresponding to the small floor frame 310A) to the top surface of the small floor frame 310A. Furthermore, it is possible to attach one floor panel 320 (a floor panel 320 corresponding to the medium-sized floor frame 310B) to the top surface of the medium-sized floor frame 310B. Also, it is possible to attach one floor panel 320 (a floor panel 320 corresponding to the large floor frame 310C) to the top surface of the large floor frame 310C. In this case, the configuration may allow for the attachment of two floor panels 320 (two floor panels 320 corresponding to the small floor frame 310A) to the upper surface of the medium-sized floor frame 310B. Alternatively, the configuration may allow for the attachment of six floor panels 320 (six floor panels 320 corresponding to the small floor frame 310A) to the upper surface of the large floor frame 310C.

[0068] The floor panel 320 is fixed to the upper surfaces of the floor frames 310A, 310B, and 310C by screw fastening. Specifically, the upper surface of the floor panel 320 is provided with multiple screw holes s. When attaching the floor panel 320 to the upper surfaces of the floor frames 310A, 310B, and 310C, first, T-slot nuts are inserted into T-slots TG provided on the upper sides of the frames 311a and 311b of the floor frames 310A, 310B, and 310C. Next, the floor panel 320 is placed on the upper surfaces of the floor frames 310A, 310B, and 310C. Then, the screws inserted through each screw hole s are fitted into the screw holes provided in the T-slot nuts. This fixes the floor panel 320 to the upper surfaces of the floor frames 310A, 310B, and 310C. At this time, the upper surface (top) of the screw is lower than the upper surface of the floor panel 320. That is, the upper surface of the screw is recessed (recessed, embedded, or indented) relative to the upper surface of the floor panel 320. This makes it possible to prevent the claw member 411a from getting caught on the screw.

[0069] (Various floor parts) Figure 12 is a perspective view showing various floor components. In Figure 12, various floor parts are shown attached to the mounting portion 321 of the floor panel 320. In this embodiment, various floor parts are provided, such as columnar parts 330, hemispherical parts 331, conical parts 332, and spherical parts 333. As shown in Figure 12, the column part 330 is formed in a cylindrical shape. The column part 330 is made of an alloy such as stainless steel. The diameter of the bottom surface of the column part 330 is larger than the diameter of the mounting portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, the configuration is such that the claw member 411a does not fit between the bottom surface of the column part 330 and the upper surface of the mounting portion 321. As a result, when the column part 330 is attached to the mounting portion 321, the mounting portion 321 is covered by the bottom surface of the column part 330, making it possible to prevent the claw member 411a from catching on the mounting portion 321. The bottom surface of the column part 330 is provided with a threaded portion. Additionally, the top surface of the column part 330 is provided with a screw hole. The column part 330 can be attached to the top surface of the floor panel 320 by fitting its threaded portion into the mounting portion 321. Furthermore, the column part 330 can be attached to the upper or outer surface of the frames 311a and 311b of the floor frames 310A, 310B, and 310C via a T-groove nut. In this case, the T-groove nut is inserted into the T-groove TG provided on the upper or outer surface of the frames 311a and 311b, and the threaded portion of the column part 330 is fitted into the threaded hole provided in the T-groove nut. In this embodiment, multiple types of columnar parts 330 with different lengths are provided. In particular, by fitting the threaded portion of one columnar part 330 into the threaded hole of another columnar part 330, it is possible to connect one columnar part 330 to other columnar parts 330 in a series. For example, prepare a columnar part 330 with a length of 25.0 mm and another columnar part 330 with a length of 62.5 mm. This makes it possible to construct floor parts of various lengths, such as 25.0 mm (1 x 25.0 mm column part 330), 50.0 mm (2 x 25.0 mm column parts 330), 62.5 mm (1 x 62.5 mm column part 330), 75.0 mm (3 x 25.0 mm column parts 330), 87.5 mm (1 x 25.0 mm column part 330 + 1 x 62.5 mm column part 330), and 100.0 mm (4 x 25.0 mm column parts 330), by connecting one or more column parts 330.

[0070] The hemispherical part 331 is formed in a hemispherical shape. The hemispherical part 331 is made of resin, rubber, metal, or the like. In particular, multiple hemispherical parts 331 made of different materials may be prepared. In this case, the multiple hemispherical parts 331 shall be made of materials with different coefficients of friction. This makes it possible to make the coefficient of friction different for each hemispherical part 331. As a result, the slipperiness of the prize P in contact with the hemispherical part 331 changes depending on the type of hemispherical part 331 used, and it becomes possible to change the difficulty of winning the prize P. Furthermore, the outer surface (surface / outer surface) of the hemispherical part 331 may be formed by combining multiple materials with different coefficients of friction. For example, a predetermined portion of the outer surface of the hemispherical part 331 may be formed from a first material, while other portions may be formed from a second material with a higher coefficient of friction compared to the first material. This makes it possible to vary the coefficient of friction on the outer surface of the hemispherical part 331 depending on the part. As a result, the slipperiness of the prize P in contact with the hemispherical part 331 changes depending on the orientation in which the hemispherical part 331 is installed, making it possible to change the difficulty of winning the prize P. The diameter of the bottom surface of the hemispherical part 331 is larger than the diameter of the mounting portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, the configuration is such that the claw member 411a does not fit between the bottom surface of the hemispherical part 331 and the upper surface of the mounting portion 321. As a result, when the hemispherical part 331 is attached to the mounting portion 321, the bottom surface of the hemispherical part 331 covers the mounting portion 321, making it possible to prevent the claw member 411a from catching on the mounting portion 321. The bottom surface of the hemispherical part 331 is provided with a threaded portion. The hemispherical part 331 can be attached to the top surface of the floor panel 320 by fitting its threaded portion into the mounting portion 321. The hemispherical part 331 can also be attached to the top surface of the columnar part 330 by fitting its threaded portion into the screw hole of the columnar part 330.

[0071] The conical part 332 is formed in a conical shape. The conical part 332 is made of resin, rubber, metal, or the like. In particular, multiple cone-shaped parts 332 made of different materials may be prepared. In this case, the multiple cone-shaped parts 332 shall be made of materials with different coefficients of friction. This makes it possible to make the coefficient of friction different for each cone-shaped part 332. As a result, the slipperiness of the prize P in contact with the cone-shaped part 332 changes depending on the type of cone-shaped part 332 used, and it becomes possible to change the difficulty of winning the prize P. Furthermore, the outer surface (surface / outer surface) of the cone-shaped part 332 may be formed by combining multiple materials with different coefficients of friction. For example, a predetermined portion of the outer surface of the cone-shaped part 332 may be formed from a first material, while other portions may be formed from a second material with a higher coefficient of friction compared to the first material. This makes it possible to vary the coefficient of friction on the outer surface of the cone-shaped part 332 depending on the part. As a result, the slipperiness of the prize P in contact with the cone-shaped part 332 changes depending on the orientation in which the cone-shaped part 332 is installed, making it possible to change the difficulty of winning the prize P. The diameter of the base of the conical part 332 is larger than the diameter of the mounting portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, the configuration is such that the claw member 411a does not fit between the base of the conical part 332 and the upper surface of the mounting portion 321. As a result, when the conical part 332 is attached to the mounting portion 321, the base of the conical part 332 covers the mounting portion 321, making it possible to prevent the claw member 411a from catching on the mounting portion 321. The bottom surface of the conical part 332 is provided with a threaded portion. The conical part 332 can be attached to the top surface of the floor panel 320 by fitting its threaded portion into the mounting portion 321. The conical part 332 can also be attached to the top surface of the columnar part 330 by fitting its threaded portion into the screw hole of the columnar part 330.

[0072] The spherical part 333 comprises a spherical portion 333a and a cylindrical portion 333b fixed to the bottom of the spherical portion 333a. The spherical portion 333a is formed in a spherical shape. The spherical portion 333a is made of resin, rubber, metal, or the like. In particular, multiple spherical parts 333 made of different materials for the spherical portion 333a may be prepared. In this case, the spherical portion 333a of the multiple spherical parts 333 shall be formed from materials with different coefficients of friction. This makes it possible to make the coefficient of friction of the spherical portion 333a different for each spherical part 333. As a result, the slipperiness of the prize P, D-ring, etc. that come into contact with the spherical portion 333a changes depending on the type of spherical part 333 used, making it possible to change the difficulty of obtaining the prize P. Furthermore, in each spherical part 333, the outer surface (surface / outer surface) of the spherical part 333a may be formed by combining multiple materials with different coefficients of friction. For example, a predetermined portion of the outer surface of the spherical part 333a may be formed from a first material, while other portions may be formed from a second material with a higher coefficient of friction compared to the first material. This makes it possible to vary the coefficient of friction on the outer surface of the spherical part 333a depending on the part. As a result, the slipperiness of prizes P, D-rings, etc. that come into contact with the spherical part 333a changes depending on the orientation in which the spherical part 333 is installed, making it possible to change the difficulty of obtaining the prizes P. The cylindrical portion 333b is formed in a cylindrical shape. The cylindrical portion 333b is made of an alloy such as stainless steel. The diameter of the bottom surface of the cylindrical portion 333b is larger than the diameter of the mounting portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, the configuration is such that the claw member 411a does not fit between the bottom surface of the cylindrical portion 333b and the upper surface of the mounting portion 321. As a result, when the spherical part 333 is attached to the mounting portion 321, the mounting portion 321 is covered by the bottom surface of the cylindrical portion 333b, making it possible to prevent the claw member 411a from catching on the mounting portion 321. A threaded portion is provided on the bottom surface of the cylindrical portion 333b. The spherical portion 333 can be attached to the top surface of the floor panel 320 by fitting its threaded portion into the mounting portion 321. The spherical portion 333 can also be attached to the top surface of the columnar portion 330 by fitting its threaded portion into the screw hole of the columnar portion 330. Furthermore, the spherical part 333 can be attached to the upper or outer surface of the frames 311a, 311b of the floor frames 310A, 310B, and 310C via a T-groove nut. In this case, the T-groove nut is inserted into the T-groove TG provided on the upper or outer surface of the frames 311a, 311b, and the threaded portion of the spherical part 330 is fitted into the threaded hole provided in the T-groove nut. In this embodiment, the spherical part 333 is composed of a spherical portion 333a and a cylindrical portion 333b fixed to the bottom of the spherical portion 333a. However, the spherical part 333 may be composed without the cylindrical portion 333b. In such a configuration, a threaded portion is provided on the bottom surface of the spherical portion 333a.

[0073] (Flexible rod 340) Figure 13 is a perspective view showing the flexible rod 340. Figure 14 is a cross-sectional view perpendicular to the central axis of the flexible rod 340. Figure 15 is a cross-sectional view along the central axis of the flexible rod 340. As shown in Figure 13, the flexible rod 340 is composed of a rod portion 341 and ball joint portions 342 attached to each end of the rod portion 341 in the longitudinal direction (the direction in which the rod portion 341 extends). The rod portion 341 is composed of two cylindrical bodies 341a and 341b. That is, the rod portion 341 is formed by the insertion (fitting) of all or part of cylindrical body 341a into the interior of cylindrical body 341b. The cylindrical body 341a is inserted into the cylindrical body 341b so as to be slidable relative to the cylindrical body 341b. In this case, the cylindrical body 341a can be slid in a direction to be housed inside the cylindrical body 341b (hereinafter referred to as the "housed direction") or in a direction to be discharged from inside the cylindrical body 341b (hereinafter referred to as the "discharge direction"). When the cylindrical body 341a is slid in the storage direction, the rod portion 341 (flexible rod 340) contracts. Conversely, when the cylindrical body 341a is slid in the discharge direction, the rod portion 341 (flexible rod 340) extends. This makes it possible to change (adjust) the longitudinal dimension of the rod portion 341 (flexible rod 340) by sliding the cylindrical body 341a in the storage or discharge direction. As shown in Figure 14, in this embodiment, the cross-section of each cylindrical body 341a, 341b perpendicular to the longitudinal direction is teardrop-shaped. That is, on the outer circumferential surface of each cylindrical body 341a, 341b, an arcuate surface (curved surface), a flat surface, and a corner are formed along the circumferential direction. This makes it possible to change the frictional force acting on the prize P when supporting it with the outer circumferential surface of the cylindrical bodies 341a, 341b, depending on whether the prize P is supported by the arcuate surface, the flat surface, or the corner. As a result, the slipperiness of the prize P in contact with the rod portion 341 changes depending on whether the prize P is supported by the arcuate surface, the flat surface, or the corner, making it possible to change the difficulty of obtaining the prize P. Furthermore, when supporting the prize P with the outer surfaces of the cylindrical bodies 341a and 341b, it is possible to change the state of support for the prize P depending on the part of the support area. In this case, the area in contact with the prize P decreases in the order of flat surface, arcuate surface, and corner (large to small). Therefore, it is possible to stably support the prize P in the order of flat surface, arcuate surface, and corner (stable to unstable). As a result, it is possible to change the difficulty of winning the prize P depending on whether the prize P is supported by the arcuate surface, the flat surface, or the corner. Furthermore, the cross-sections perpendicular to the longitudinal direction of each cylindrical body 341a, 341b can be changed as appropriate, such as circular, polygonal (triangle, quadrilateral, pentagon, hexagon), etc.

[0074] As shown in Figure 15, each ball joint portion 342 is composed of a ball stud portion 343, a socket portion 344, and a T-slot nut portion (T-slot nut portion) 345. The ball stud portion 343 is composed of a cylindrical shaft portion 343a and a spherical portion 343b fixed to the tip of the shaft portion 343a. The socket portion 344 comprises a main body portion 344a and a locking mechanism 344b attached to the main body portion 344a. The main body portion 344a is formed in a cylindrical shape with an open top and a bottom. The main body portion 344a slidably holds (houses) the spherical portion 343b inside. As a result, each ball joint portion 342 can rotate (rotate circumferentially around the central axis of the ball stud portion 343 as the axis of rotation) and oscillate (change the direction and angle in which the central axis of the ball stud portion 343 extends) relative to the socket portion 344.

[0075] The locking mechanism 344b is capable of locking at least one of the rotation and oscillation of the ball stud portion 343 relative to the socket portion 344. In this embodiment, the locking mechanism 344b is configured to lock the rotation of the ball stud portion 343 relative to the socket portion 344, but not the oscillation of the ball stud portion 343 relative to the socket portion 344. However, the locking mechanism 344b may be configured to lock both the rotation and oscillation of the ball stud portion 343 relative to the socket portion 344. In other words, the locking mechanism 344b is configured to include a cam lever 344c. The cam lever 344c can be operated (displaced) to a locked position or an unlocked position. Here, the outer circumferential surface of the main body 344a is provided with a slit (not shown) that extends in the direction in which the central axis extends. When the cam lever 344c is operated to the locked position, the spacing between the slits in the main body 344a narrows, and the inner circumference of the main body 344a contracts. As a result, the spherical part 343b is tightened by the inner surface of the main body 344a, and the rotation of the ball stud part 343 relative to the socket part 344 is locked. At this time, the swinging of the ball stud part 343 relative to the socket part 344 is not locked. On the other hand, when the cam lever 344c is operated to the release position, the spacing between the slits provided in the main body 344a widens, and the inner circumference of the main body 344a extends. As a result, the tightening of the spherical part 343b by the inner surface of the main body 344a is released, allowing the ball stud part 343 to rotate and swing relative to the socket part 344. The T-slot nut portion 345 is fixed to the bottom surface of the main body portion 344a. In plan view, the T-slot nut portion 345 is formed in the shape of a rectangular plate. In particular, the longitudinal dimension (length) of the T-slot nut portion 345 is larger than the width of each T-slot TG,tg. On the other hand, the dimension (width) of the T-slot nut portion 345 in the direction perpendicular to the longitudinal direction is smaller than the width of each T-slot TG,tg.

[0076] Each ball joint portion 342 is attached to the end of the rod portion 341 by fitting its shaft portion 343a inside the cylindrical bodies 341a and 341b. In this case, the central axis of the shaft portion 343a and the central axes of the cylindrical bodies 341a and 341b are arranged coaxially. As a result, when the cam lever 344c of each ball joint portion 342 is operated to the release position, the rod portion 341 can rotate and swing relative to the T-groove nut portion 345 fixed to the ball joint portion 342. On the other hand, when the cam lever 344c of each ball joint portion 342 is operated to the locked position, only the swinging of the rod portion 341 relative to the T-groove nut portion 345 fixed to the ball joint portion 342 becomes possible, and rotation becomes impossible. As described above, the flexible rod 340 allows for changing (adjusting) the angle of the rod portion 341 relative to each socket portion 344. Furthermore, the flexible rod 340 allows for changing (adjusting) the distance between the pair of ball joint portions 342 (T-groove nut portions 345) by contracting or extending the rod portion 341.

[0077] The flexible rod 340 can be attached to the upper or inner surface of the base frame 237. In other words, when attaching the flexible rod 340 to the upper or inner surface (hereinafter referred to as the "fixing surface") of the base frame 237, first, the T-groove nut portion 345 provided at the end of the flexible rod 340 is inserted into the T-groove tg provided on the fixing surface of the base frame 237. At this time, by rotating the socket portion 344 to align the longitudinal direction of the T-groove nut portion 345 with the longitudinal direction of the T-groove tg, it becomes possible to insert the T-groove nut portion 345 into the T-groove tg. Next, the socket portion 344 is rotated to rotate the T-slot nut portion 345 by 90° in a predetermined direction. As a result, within the T-slot tg, the T-slot nut portion 345 is displaced from a state parallel to the T-slot tg (released state) to a state perpendicular to the T-slot tg (fixed state). Consequently, the T-slot nut portion 345 is fixed within the T-slot tg. This fixes the end of the flexible rod 340 to the base frame 237 with the bottom surface of the socket portion 344 (main body portion 344a) in close contact with the fixing surface. In particular, when the T-slot nut portion 345 is displaced to a state perpendicular to the T-slot tg (fixed state), the position of the T-slot nut portion 345 within the T-slot tg is fixed. As a result, it becomes impossible to change the fixed position of the socket portion 344 in the T-slot tg. On the other hand, when the T-groove nut portion 345 is displaced to a state parallel to the T-groove tg (released state), the position of the T-groove nut portion 345 within the T-groove tg is released. This makes it possible to change the fixed position of the socket portion 344 in the T-groove tg. As described above, the end of the flexible rod 340 is attached to the fixed surface of the base frame 237. In particular, a T-groove tg is provided on the upper surface of the base frame 237, extending from one end to the other in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 at any position in the longitudinal direction on the upper surface of the base frame 237. Therefore, the fixing position of the flexible rod 340 to the upper surface of the base frame 237 can be set arbitrarily. Similarly, a T-groove tg is provided on the inner surface of the base frame 237, extending from one end to the other in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 at any position in the longitudinal direction on the inner surface of the base frame 237. Therefore, the fixing position of the flexible rod 340 relative to the inner surface of the base frame 237 can be arbitrarily set. In this case, when the T-groove nut portion 345 is displaced to be parallel to the T-groove tg (released state), the socket portion 344 can be slid relative to the base frame 237 while the T-groove nut portion 345 remains inserted into the T-groove tg. This makes it possible to change (adjust) the fixing position of the socket portion 344 relative to the base frame 237 without removing the T-groove nut portion 345 from the T-groove tg.

[0078] Furthermore, the flexible rod 340 can be attached to the floor frames 310A, 310B, and 310C. In other words, when attaching the flexible rod 340 to the floor frames 310A, 310B, and 310C, first, the T-groove nut portion 345 provided at the end of the flexible rod 340 is inserted into the T-groove TG provided on the upper or outer surface (hereinafter referred to as the "fixed surface") of one of the four frames 311a, 311b (hereinafter referred to as the "fixed frame") that make up the floor frames 310A, 310B, and 310C. At this time, by rotating the socket portion 344 to align the longitudinal direction of the T-groove nut portion 345 with the longitudinal direction of the T-groove TG, it becomes possible to insert the T-groove nut portion 345 into the T-groove TG. Next, the socket portion 344 is rotated to rotate the T-slot nut portion 345 by 90° in a predetermined direction. As a result, within the T-slot TG, the T-slot nut portion 345 is displaced from a state parallel to the T-slot TG (released state) to a state perpendicular to the T-slot TG (fixed state). Consequently, the T-slot nut portion 345 is fixed within the T-slot TG. This fixes the end of the flexible rod 340 to the fixing frame with the bottom surface of the socket portion 344 (main body portion 344a) in close contact with the fixing surface. In particular, when the T-slot nut portion 345 is displaced to a state perpendicular to the T-slot TG (fixed state), the position of the T-slot nut portion 345 within the T-slot TG is fixed. As a result, it becomes impossible to change the fixed position of the socket portion 344 in the T-slot TG. On the other hand, when the T-slot nut portion 345 is displaced to a state parallel to the T-slot TG (released state), the position of the T-slot nut portion 345 within the T-slot TG is released. This makes it possible to change the fixed position of the socket portion 344 in the T-slot TG. As described above, the end of the flexible rod 340 is attached to the fixed surface of the floor frames 310A, 310B, and 310C.

[0079] In particular, a T-groove TG is provided on the upper surface of each frame 311a, 311b, extending from one end to the other in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 at any position in the longitudinal direction on the upper surface of each frame 311a, 311b. Therefore, the fixing position of the flexible rod 340 to the upper surface of each frame 311a, 311b can be set arbitrarily. Similarly, a T-groove TG is provided on the outer surface of each frame 311a, 311b, extending from one end to the other in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 at any position in the longitudinal direction on the outer surface of each frame 311a, 311b. Therefore, the fixing position of the flexible rod 340 to the outer surface of each frame 311a, 311b can be arbitrarily set. In this case, when the T-groove nut portion 345 is displaced to be parallel to the T-groove TG (released state), the socket portion 344 can be slid relative to the frames 311a and 311b while the T-groove nut portion 345 remains inserted into the T-groove TG. This makes it possible to change (adjust) the fixing position of the socket portion 344 relative to the frames 311a and 311b without removing the T-groove nut portion 345 from the T-groove TG.

[0080] As described above, the flexible rod 340 can be attached so as to span between the base frame 237 of any of the three sets of individual lifting frames 231 to 233 located in the left frame unit 221 and the base frame 237 of any of the three sets of individual lifting frames 234 to 236 located in the right frame unit 222. Furthermore, a flexible rod 340 can be attached so as to span between the base frame 237 of any of the three sets of individual lifting frames 231 to 233 located in the left frame unit 221 and the floor frames 310A, 310B, and 310C attached to the base frame 237 of any of the three sets of individual lifting frames 234 to 236 located in the right frame unit 222. Furthermore, the flexible rod 340 can be attached so as to span between the floor frames 310A, 310B, and 310C, which are attached to the base frame 237 of any of the three sets of individual lifting frames 231 to 233 located in the left frame unit 221, and the base frame 237 of any of the three sets of individual lifting frames 234 to 236 located in the right frame unit 222. Furthermore, a flexible rod 340 can be attached so as to span between the floor frames 310A, 310B, and 310C attached to the base frame 237 of any of the three sets of individual lifting frames 231 to 233 located in the left frame unit 221, and the floor frames 310A, 310B, and 310C attached to the base frame 237 of any of the three sets of individual lifting frames 234 to 236 located in the right frame unit 222. In particular, with the flexible rod 340, the slipperiness of the prize P placed on the rod portion 341 can be changed (adjusted) by changing (adjusting) the orientation of the outer surface of the rod portion 341. In this case, when the rod portion 341 is positioned with the corners facing upwards, it is possible to make the prize P placed on the rod portion 341 less likely to slip compared to when the arcuate surface of the rod portion 341 is positioned with the arcuate surface facing upwards. Furthermore, in the flexible rod 340, the rod portion 341 is configured to be extendable and retractable, and the swing of the rod portion 341 relative to the socket portion 344 is not locked when the cam lever 344c is operated to the locked position. As a result, when the individual lifting frames 234-236 on which the flexible rod 340 is supported are raised or lowered relative to the overall lifting frame 220 with the cam lever 344c of the flexible rod 340 operated to the locked position, the angle of the rod portion 341 relative to the socket portion 344 changes accordingly, and as a result, the vertical inclination angle of the flexible rod 340 changes. Therefore, even when the cam lever 344c of the flexible rod 340 is operated to the locked position, it is possible to raise or lower the individual lifting frames 234-236 on which the flexible rod 340 is supported relative to the overall lifting frame 220. In this case, when the cam lever 344c of the flexible rod 340 is operated to the locked position, the rotational frictional force of the ball stud portion 343 relative to the socket portion 344 increases, and the rotation of the rod portion 341 (ball stud portion 343) relative to the socket portion 344 is locked. As a result, even when the individual lifting frames 234-236 on which the flexible rod 340 is stretched are raised or lowered relative to the overall lifting frame 220 while the cam lever 344c of the flexible rod 340 is operated to the locked position, the rod portion 341 will not rotate relative to the socket portion 344 in response.

[0081] (Flexible rod 840) Next, a flexible rod 840, which is a modified example of the flexible rod 340, will be described. Figure 39 is a perspective view showing the flexible rod 840. Figure 40 is a perspective view showing how the flexible rod 840 is attached to the floor frame 810. In this embodiment, a flexible rod 340 is used as a component of the prize placement mechanism 30. However, a flexible rod 840 may be used instead of the flexible rod 340 as a component of the prize placement mechanism 30. As shown in Figure 39, the flexible rod 840 is composed of a rod portion 850 and joint portions 860 attached to each end of the rod portion 850 in the longitudinal direction (the direction in which the rod portion 850 extends). The rod portion 850 is composed of two cylindrical bodies 851 and 852. That is, the rod portion 850 is formed by the insertion (fitting) of all or part of cylindrical body 851 into the interior of cylindrical body 852. The cylindrical body 851 is inserted into the cylindrical body 852 so as to be slidable relative to the cylindrical body 852. In this case, the cylindrical body 851 can be slid in a direction to be housed inside the cylindrical body 851 (hereinafter referred to as the "housed direction") or in a direction to be discharged from inside the cylindrical body 852 (hereinafter referred to as the "discharge direction"). When the cylindrical body 851 is slid in the storage direction, the rod portion 850 (flexible rod 840) contracts. Conversely, when the cylindrical body 851 is slid in the discharge direction, the rod portion 850 (flexible rod 840) extends. This makes it possible to change (adjust) the longitudinal dimension of the rod portion 850 (flexible rod 840) by sliding the cylindrical body 851 in the storage or discharge direction. The cross-sections of each cylindrical body 851 and 852 perpendicular to their longitudinal direction are circular. However, the cross-sections of each cylindrical body 841a and 841b perpendicular to their longitudinal direction can be changed as appropriate to polygons (triangles, quadrilaterals, pentagons, hexagons, etc.).

[0082] Each joint portion 860 has the same configuration as the fixing member 820. That is, each joint portion 860 is composed of a cylindrical shaft portion 861, an operating portion 862 fixed to one end of the shaft portion 861, a T-slot nut portion (T-slot nut portion) 863 fixed to the other end of the shaft portion 861, and a fixing nut 864 screwed onto the shaft portion 861. In each joint section 860, the central axis of the shaft section 861, the central axis of the operating section 862, the central axis of the fixing nut 864, and the central axis of the T-groove nut section 863 are arranged coaxially. This makes it possible to rotate the T-groove nut section 863 via the shaft section 861 by rotating the operating section 862. The T-slot nut portion 863 is formed in a roughly rectangular plate shape when viewed from above. In particular, the longitudinal dimension (length) of the T-slot nut portion 863 is greater than the width of each T-slot TGR,tg. On the other hand, the dimension (width) of the T-slot nut portion 863 in the direction perpendicular to the longitudinal direction is smaller than the width of each T-slot TGR,tg. The fixing nut 864 has a through hole (not shown) through which the shaft portion 861 is inserted. A screw groove is provided on the inner circumferential surface of the through hole. The outer circumferential surface of the shaft portion 861 is provided with screw threads that engage with the screw grooves provided on the inner circumferential surface of the through hole of the fixing nut 864. The screw threads are provided in a predetermined range at one end of the shaft portion 861. The fixing nut 864 is then screwed onto the screw threads provided on the outer circumferential surface of the shaft portion 861. As a result, the fixing nut 864 can be moved along the shaft portion 861 by rotating it around the shaft portion 861. In this case, the fixing nut 864 can be moved between the T-groove nut portion 863 and the operating portion 862. Specifically, the fixing nut 864 can be moved toward the T-groove nut portion 863 by rotating it clockwise around the shaft portion 861. On the other hand, the fixing nut 864 can be moved toward the operating part 862 by rotating it counterclockwise around the shaft part 861. As a result, in each joint part 860, the distance between the fixing nut 864 and the T-groove nut part 863 can be changed by moving the fixing nut 864.

[0083] Each joint 860 is attached to the end of the rod 850 via an elastic body 870 such as rubber. This allows the flexible rod 840 to arbitrarily change the angle of the rod 850 relative to each joint 860. Furthermore, the flexible rod 840 allows the distance between a pair of joint 860s to be changed (adjusted) by contracting or extending the rod 850.

[0084] The flexible rod 840 can be attached to the floor frame 810. As shown in Figure 40, when attaching the flexible rod 840 to the floor frame 810, first, the T-groove nut portion 863 of the joint portion 860 provided at the end of the flexible rod 840 is inserted into the T-groove TGR provided on the upper or outer surface (hereinafter referred to as the "fixed surface") of one of the four frames 811 that make up the floor frame 810 (hereinafter referred to as the "fixed frame"). At this time, by rotating the operating portion 862 of the joint portion 860 to align the longitudinal direction of the T-groove nut portion 863 with the longitudinal direction of the T-groove TGR, it becomes possible to insert the T-groove nut portion 863 into the T-groove TGR. Next, the operating part 862 of the joint part 860 is rotated to rotate the T-groove nut part 863 by 90° in a predetermined direction. As a result, within the T-groove TGR, the T-groove nut part 863 is displaced from a state parallel to the T-groove TGR (released state) to a state perpendicular to the T-groove TGR (fixed state). Next, the fixing nut 864 of the joint portion 860 is rotated clockwise and moved toward the T-groove nut portion 863, thereby sandwiching the fixing surface between the T-groove nut portion 863 and the fixing nut 864. As a result, the end of the flexible rod 840 is fixed to the fixing frame with the end face of the fixing nut 864 and the fixing surface in close contact. As described above, the flexible rod 840 is attached to the fixed surface of the floor frame 810. Similarly, the flexible rod 840 can be attached to the upper or inner surface of the base frame 237. When attaching the flexible rod 840 to the upper or inner surface (hereinafter referred to as the "fixing surface") of the base frame 237, first, the T-groove nut portion 863 of the joint portion 860 provided at the end of the flexible rod 840 is inserted into the T-groove tg provided on the fixing surface of the base frame 237. At this time, by rotating the operating portion 862 of the joint portion 860 to align the longitudinal direction of the T-groove nut portion 863 with the longitudinal direction of the T-groove tg, it becomes possible to insert the T-groove nut portion 863 into the T-groove tg. Next, the operating part 862 of the joint part 860 is rotated to rotate the T-groove nut part 863 by 90° in a predetermined direction. As a result, within the T-groove tg, the T-groove nut part 863 is displaced from a state parallel to the T-groove tg (released state) to a state perpendicular to the T-groove tg (fixed state). Next, the fixing nut 864 of the joint portion 860 is rotated clockwise and moved toward the T-groove nut portion 863, thereby sandwiching the fixing surface between the T-groove nut portion 863 and the fixing nut 864. As a result, the end of the flexible rod 840 is fixed to the base frame 237 with the end face of the fixing nut 864 and the fixing surface in close contact. As described above, the flexible rod 840 is attached to the fixed surface of the base frame 237.

[0085] (Example of the configuration of the prize distribution mechanism 30) Next, we will describe an example configuration of the prize distribution mechanism 30. As described above, in this embodiment, by combining a small floor frame 310A, a medium floor frame 310B, a large floor frame 310C, a floor panel 320, various floor parts, a flexible rod 340, etc., it is possible to construct a prize placement mechanism 30 of various shapes. The following is an example of a prize distribution mechanism 30.

[0086] (Example 1) First, I will explain the prize distribution mechanism 30 related to the first example. Figure 16 is a diagram showing an example configuration of the prize distribution mechanism 30 according to the first example. Figure 17 is an enlarged view of the first floor panel 320 constituting the prize distribution mechanism 30 according to the first example. Figure 18 is an enlarged view of the second floor panel 320 constituting the prize distribution mechanism 30 according to the first example. Figure 19 is a perspective view showing an example of the arrangement of floor parts in the floor panel 320 according to the first modified example. Figure 20 is a perspective view showing an example of the arrangement of floor parts in the floor panel 320 according to the second modified example. Figure 21 is a perspective view showing an example of the arrangement of floor parts in the floor panel 320 according to the third modified example. As shown in Figure 16, the prize placement mechanism 30 according to the first example has two prize placement surfaces A and B configured in the game area GE, which are surfaces on which prizes P can be placed (hereinafter referred to as "prize placement surfaces"). The two prize placement surfaces A and B are spaced apart from each other and have different heights. In other words, the prize placement mechanism 30 according to the first example is composed of a first medium-sized floor frame 310B and a second medium-sized floor frame 310B. The first medium-sized floor frame 310B is attached to the front individual lifting frame 231 of the three sets of individual lifting frames 231-233 located on the left frame unit 221. Specifically, the first medium-sized floor frame 310B is attached to the inner surface of the base frame 237 of the individual lifting frame 231. As a result, the first medium-sized floor frame 310B is positioned to extend from the inner surface of the base frame 237 of the individual lifting frame 231 toward the game area GE. In this configuration, the first medium-sized floor frame 310B is attached to the inner surface of the base frame 237 of the individual lifting frame 231 by fixing two fixing members 313 provided on one side of the base frame 310B to T-grooves tg provided on the inner surface of the base frame 237. As a result, the first medium-sized floor frame 310B is attached to the individual lifting frame 231 in a cantilevered manner. The second medium-sized floor frame 310B is attached to the middle individual lifting frame 235, one of three sets of individual lifting frames 234-236 located in the right-side frame unit 222. Specifically, the second medium-sized floor frame 310B is attached to the inner surface of the base frame 237 of the individual lifting frame 235. As a result, the second medium-sized floor frame 310B is positioned to extend from the inner surface of the base frame 237 of the individual lifting frame 235 toward the game area GE. In this configuration, the second medium-sized floor frame 310B is attached to the inner surface of the base frame 237 of the individual lifting frame 235 by fixing two fixing members 313 located on one side of the base frame 210B to T-grooves tg located on the inner surface of the base frame 237 of the individual lifting frame 235. As a result, the second medium-sized floor frame 310B is attached to the individual lifting frame 235 in a cantilevered manner.

[0087] A first floor panel 320 is attached to the upper surface of the first medium-sized floor frame 310B. As a result, the upper surface of the first floor panel 320 forms a nearly horizontal first prize placement surface A. Furthermore, multiple columnar parts 330 are attached to the first prize placement surface A in a predetermined pattern. In this case, the multiple columnar parts 330 are of the same type (length). Each columnar part 330 is attached to the mounting portion 321 of the floor panel 320. As a result, as shown in Figure 17, it becomes possible to place a portion of the prize P on the first prize placement surface A in a floating state. That is, on the first prize placement surface A, it becomes possible to support the bottom surface of the prize P using the upper surface of the first floor panel 320 and the tip of the column part 330. Therefore, it becomes possible to float a portion of the bottom surface of the prize P relative to the upper surface of the first floor panel 320. Thus, for example, when placing a box-shaped prize P on the first prize placement surface A, it becomes possible to create a space for inserting the claw member 411a between the upper surface of the first floor panel 320 and the bottom surface of the prize P.

[0088] A second floor panel 320 is attached to the upper surface of the second medium-sized floor frame 310B. As a result, the upper surface of the second floor panel 320 forms a nearly horizontal second prize placement surface B. Furthermore, multiple columnar parts 330 are attached to the second prize placement surface B in a predetermined pattern. In particular, the second prize placement surface B is composed of multiple prize placement sections. Each prize placement section is composed of three columnar parts 330. In this case, of the three columnar parts 330, two are short columnar parts 330 (hereinafter referred to as "short columnar parts 330"), and one is a long columnar part 330 (hereinafter referred to as "long columnar part 330"). Each prize placement section is constructed by positioning the long columnar part 330 between the two short columnar parts 330 and at a position behind the two short columnar parts 330. Each columnar part 330 is attached to the mounting section 321 of the floor panel 320. As a result, as shown in Figure 18, it becomes possible to place the prize P upright on the second prize placement surface B. That is, on the second prize placement surface B, each prize placement section can support the prize P in an upright position. In this case, the front of the prize P is supported by two short columnar parts 330 and the back of the prize P is supported by one long columnar part 330. Therefore, for example, when placing a flat, bag-shaped prize P on the second prize placement surface B, it becomes possible to arrange the prize P three-dimensionally.

[0089] In the prize placement mechanism 30 according to the first example, the first medium-sized floor frame 310B and the second medium-sized floor frame 310B are attached to different individual lifting frames 231 and 235. This makes it possible to individually adjust the height of the first prize placement surface A and the second prize placement surface B. In other words, when adjusting the height of the prize placement surfaces A and B, the height of the first prize placement surface A can be adjusted by raising or lowering the individual lifting frame 231 relative to the overall lifting frame 220. Similarly, the height of the second prize placement surface B can be adjusted by raising or lowering the individual lifting frame 235 relative to the overall lifting frame 220. This allows for adjustment of the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B. Subsequently, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize gripping section 410 and each prize placing surface A and B can be adjusted all at once while maintaining the relative positional relationship (height relationship) between the first prize placing surface A and the second prize placing surface B. In other words, with the individual lifting lock mechanism 239 locking the lifting of each individual lifting frame 231 to 236 relative to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered relative to the foundation frame 210.

[0090] Based on the above, the prize distribution mechanism 30 for the first example is configured. The prize placement mechanism 30 in the first example comprises a prize placement area AE and an opening area OE within the game area GE. Specifically, within the game area GE, the prize placement area AE is formed on each prize placement surface A and B, and the opening area OE is formed around each prize placement surface A and B. In particular, within the game area GE, it becomes possible to construct multiple prize placement areas AE that are spaced apart from each other and at different heights. In the prize placement mechanism 30 according to the first example, the prize gripping unit 410 causes the prizes P placed on each prize placement surface A and B to fall from the prize placement surfaces A and B, thereby making it possible to acquire the prizes P.

[0091] Here, various floor parts can be attached to the top surface of each floor panel 320 (each prize placement surface A, B) according to the type of prize P. For example, as shown in Figure 19, when a stuffed animal is used as the prize P, a columnar floor part, which is constructed by connecting multiple columnar parts 330 in a series, is attached to the upper surface of the floor panel 320. The stuffed animal is then placed on the upper surface of the floor panel 320 so as to embrace the columnar floor part. This makes it possible to place the stuffed animal on the upper surface of the floor panel 320 in either an upright or seated position. In particular, it prevents the prize P from rolling off to the left or right due to interference from the prize gripping part 410. Furthermore, by suspending the prize P higher than the tip of the columnar floor part, it is possible to provide a game feature in which the prize P can be won by releasing the prize P from its embrace of the columnar floor part. Furthermore, as shown in Figure 20, when a cylindrical item is used as the prize P, a pair of hemispherical parts 331, a pair of conical parts 332, a pair of columnar parts 330, etc., are attached to the upper surface of the floor panel 320. This makes it possible to prevent the prize P from rolling away using a pair of floor parts, and to position the cylindrical prize P on its side on the upper surface of the floor panel 320. In this case, the difficulty of winning the prize P can be changed (adjusted) by changing (adjusting) the height of the pair of floor parts. Furthermore, as shown in Figure 21, when a spherical object is used as the prize P, multiple floor parts are attached to the upper surface of the floor panel 320 in a predetermined pattern to create a path that guides the prize P to the opening area OE. This makes it possible to guide the prize P along the path on the upper surface of the floor panel 320 and cause the prize P to fall into the opening area OE. In particular, as shown in Figure 21, by attaching wall members to the outer surface of the medium-sized floor frame 310B, it is possible to improve the game's ability to guide the prize P along the path.

[0092] (Example 2) Next, we will explain the prize distribution mechanism 30 related to the second example. Figure 22 shows an example of the configuration of the prize distribution mechanism 30 according to the second example. As shown in Figure 22, the prize placement mechanism 30 according to the second example has a pair of prize placement surfaces A and B configured in the game area GE, and it is possible to place prizes P so as to span across the pair of prize placement surfaces A and B. The pair of prize placement surfaces A and B are spaced apart from each other with an opening area OE in between. In addition, each prize placement surface A and B is inclined toward the opening area OE. In other words, the prize placement mechanism 30 according to the second example is composed of a first small floor frame 310A, a second small floor frame 310A, and a large floor frame 310C. The first small floor frame 310A is attached to the rear individual lifting frame 233, one of three sets of individual lifting frames 231-233 located on the left frame unit 221. Specifically, the first small floor frame 310A is attached to the upper side of the base frame 237 of the individual lifting frame 233. As a result, the first small floor frame 310A is positioned to extend upward from the upper side of the base frame 237 of the individual lifting frame 233. In this case, the first small floor frame 310A is attached to the upper side of the base frame 237 by fixing two fixing members 313 provided on one side thereof to T-grooves tg provided on the upper side of the base frame 237 of the individual lifting frame 233. The second small floor frame 310A is attached to the rearmost individual lifting frame 236 of the three sets of individual lifting frames 234-236 located on the right frame unit 222. Specifically, the second small floor frame 310A is attached to the upper side of the base frame 237 of the individual lifting frame 236. As a result, the second small floor frame 310A is positioned to extend upward from the upper side of the base frame 237 of the individual lifting frame 236. In this case, the second small floor frame 310A is attached to the upper side of the base frame 237 by fixing two fixing members 313 provided on one side thereof to T-grooves tg provided on the upper side of the base frame 237 of the individual lifting frame 236.

[0093] The large floor frame 310C is spanned between the first small floor frame 310A (individual lifting frame 233) and the second small floor frame 310A (individual lifting frame 236). Specifically, of the pair of vertical frames 311a that constitute the large floor frame 310C, one vertical frame 311a is attached to the upper surface of the horizontal frame 311b that constitutes the first small floor frame 310A and to the inner surface of the base frame 237 that constitutes the individual lifting frame 233. In this case, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-groove TG provided on the upper surface of the horizontal frame 311b, and the other fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237. Furthermore, of the pair of vertical frames 311a that constitute the large floor frame 310C, the other vertical frame 311a is attached to the upper surface of the horizontal frame 311b that constitutes the second small floor frame 310A and to the inner surface of the base frame 237 that constitutes the individual lifting frame 236. In this case, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-groove TG provided on the upper surface of the horizontal frame 311b, and the other fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237. As a result, the large floor frame 310C is positioned with its upper surface tilted towards the front. A flat floor panel fp is attached to the upper surface of the large floor frame 310C. The upper surface of the flat floor panel fp is flat. In other words, unlike the floor panel 320, the upper surface of the flat floor panel fp does not have a mounting portion 321. As a result, the upper surface of the flat floor panel fp forms a second prize placement surface B. In this case, the second prize placement surface B is inclined toward the front.

[0094] Furthermore, the prize placement mechanism 30 in the second example is composed of three medium-sized floor frames 310B. The three medium-sized floor frames 310B are connected in a row so that their upper surfaces are aligned on the same plane. These three connected medium-sized floor frames 310B are then spanned between the left frame unit 221 and the right frame unit 222. In the following description, of the three connected medium-sized floor frames 310B, the one located on the left will be referred to as the "left medium-sized floor frame 310B," and the one located on the right will be referred to as the "right medium-sized floor frame 310B." Specifically, the vertical frame 311a constituting the left-side medium-sized floor frame 310B is attached to the inner surface of the base frame 237 constituting the front individual lifting frame 231 and the inner surface of the base frame 237 constituting the middle individual lifting frame 232, among the three sets of individual lifting frames 231 to 233 arranged in the left-side frame unit 221. In this case, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 231, and the other fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 232. Furthermore, the vertical frame 311a that constitutes the right-side medium-sized floor frame 310B is attached to the inner surface of the base frame 237 that constitutes the front individual lifting frame 234, and the inner surface of the base frame 237 that constitutes the middle individual lifting frame 235, among the three sets of individual lifting frames 234 to 236 arranged in the right-side frame unit 222. In this case, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 234, and the other fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 235. Furthermore, the base frame 237 of individual lifting frames 232 and 235 is positioned lower than the base frame 237 of individual lifting frames 231 and 234. As a result, the three medium-sized floor frames 310B, connected in a row, are positioned with their upper surfaces tilted towards the rear. Three medium-sized floor frames 310B are connected in a row, and flat floor panels fp are attached to their upper surfaces. This creates a first prize placement surface A, formed by the upper surfaces of the flat floor panels fp. In this case, the first prize placement surface A is inclined toward the back.

[0095] In the prize placement mechanism 30 of the second example, a large floor frame 310C and three medium-sized floor frames 310B connected in a row are attached to different individual lifting frames 231 to 236. This makes it possible to individually adjust the height of the first prize placement surface A and the second prize placement surface B. In other words, when adjusting the height of each prize placement surface A and B, the height of the second prize placement surface B can be adjusted by raising and lowering the individual lifting frames 233 and 236 relative to the overall lifting frame 220. Furthermore, the inclination angle of the second prize placement surface B can be changed (adjusted) by changing (adjusting) the fixing position of the fixing member 313 of the large floor frame 310C in the T-groove TG of the small floor frame 310A. Furthermore, by raising and lowering the individual lifting frames 231, 232, 234, and 235 relative to the overall lifting frame 220, the height of the first prize placement surface A can be adjusted. In addition, by changing (adjusting) the positional relationship (height relationship) between the base frames 237 of the individual lifting frames 231 and 234 and the base frames 237 of the individual lifting frames 232 and 235, the inclination angle of the first prize placement surface A can be changed (adjusted). This allows for adjustment of the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B. Subsequently, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize gripping section 410 and each prize placement surface can be adjusted all at once while maintaining the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B. In other words, with the individual lifting lock mechanism 239 locking the lifting of each individual lifting frame 231 to 236 relative to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered relative to the foundation frame 210.

[0096] Based on the above, the prize distribution mechanism 30 for the second example is configured. The prize placement mechanism 30 in the second example comprises a prize placement area AE and an opening area OE within the game area GE. Specifically, within the game area GE, the prize placement area AE is formed on a pair of prize placement surfaces A and B, and the opening area OE is formed between the pair of prize placement surfaces A and B. In particular, in the game area GE, it becomes possible to arrange the prize P so as to span across a pair of prize placement surfaces A and B. In the second example of the prize placement mechanism 30, the prize gripping part 410 drops the prize P, which is supported by a pair of prize placement surfaces A and B, into the opening area OE, thereby enabling the acquisition of the prize P.

[0097] (Example 3) Next, we will explain the prize distribution mechanism 30 related to the third example. Figure 23 shows an example of the configuration of the prize distribution mechanism 30 according to the third example. As shown in Figure 23, the prize placement mechanism 30 according to the third example has two prize hanging parts C and D in the game area GE, which are parts from which prizes P can be suspended (hereinafter referred to as "prize hanging parts"). In other words, the prize distribution mechanism 30 in the third example is configured to include a large floor frame 310C. The large floor frame 310C is spanned between the left frame unit 221 and the right frame unit 222. Specifically, of the pair of vertical frames 311a that constitute the large floor frame 310C, one vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the middle individual lifting frame 232 and the inner surface of the base frame 237 that constitutes the rear individual lifting frame 233, among the three sets of individual lifting frames 231 to 233 arranged in the left frame unit 221. In this case, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 232, and the other fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 233. Furthermore, of the pair of vertical frames 311a that constitute the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the middle individual lifting frame 235 and the inner surface of the base frame 237 that constitutes the rear individual lifting frame 236, among the three sets of individual lifting frames 234 to 236 arranged in the right frame unit 222. In this case, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 235, and the other fixing member 313 is fixed to a T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 236. Furthermore, the base frame 237 of individual lifting frames 233 and 236 is positioned lower than the base frame 237 of individual lifting frames 232 and 235. As a result, the large floor frame 310C is positioned with its upper surface tilted toward the rear. In other words, of the pair of horizontal frames 311b that make up the large floor frame 310C, the front horizontal frame 311b is positioned higher than the rear horizontal frame 311b.

[0098] Two spherical parts 333 are attached to the outer surface of the front horizontal frame 311b that constitutes the large floor frame 310C. Each spherical part 333 is fixed to a T-groove TG provided on the outer surface of the horizontal frame 311b via a T-groove nut. Here, the fixing position of each spherical part 333 can be changed (adjusted) as appropriate along the T-groove TG. In the prize placement mechanism 30 of the third example, the tilt angle of each spherical part 333 can be changed (adjusted) by changing (adjusting) the positional relationship (height relationship) between the base frame 237 of the individual lifting frames 232 and 235 and the base frame 237 of the individual lifting frames 233 and 236. Subsequently, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize gripping section 410 and each spherical part 333 can be adjusted all at once while maintaining the inclination angle of each spherical part 333. In other words, with the individual lifting lock mechanism 239 locking the lifting of each individual lifting frame 231 to 236 relative to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered relative to the foundation frame 210.

[0099] Based on the above, the prize distribution mechanism 30 for the third example is configured. The prize placement mechanism 30 according to the third example comprises a prize placement area AE and an opening area OE within the game area GE. Specifically, prize hanging parts C and D are formed on the spherical portion 333a of each spherical part 333. Prizes P can be suspended from each prize hanging part C and D via D-rings dr. As a result, the prize placement area AE is formed below each prize hanging part C and D. Furthermore, the opening area OE is formed below the prizes P suspended from each prize hanging part C and D. In particular, in the game area GE, it becomes possible to place prizes P suspended above the opening area OE. Furthermore, in the prize placement mechanism 30 according to the third example, the prize gripping part 410 can detach the D-ring dr, which is hooked onto each prize hanging part C, D, from the prize hanging parts C, D, thereby making it possible to obtain the prize P connected to the D-ring dr.

[0100] (Example 4) Next, we will explain the prize distribution mechanism 30 related to the fourth example. Figure 24 shows an example of the configuration of the prize distribution mechanism 30 according to the fourth example. As shown in Figure 24, the prize placement mechanism 30 according to the fourth example consists of two prize hanging parts C and D in the game area GE, which are parts from which prizes P can be suspended (hereinafter referred to as "prize hanging parts"). In addition, one prize display part E is configured in the game area GE as a part from which prizes P can be displayed (hereinafter referred to as "prize display part"). In other words, the prize distribution mechanism 30 in the fourth example is configured to include a large floor frame 310C. The large floor frame 310C is spanned between the individual lifting frame 233 located on the left frame unit 221 and the individual lifting frame 236 located on the right frame unit 222. Specifically, of the pair of vertical frames 311a that constitute the large floor frame 310C, one vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 233. In this case, two fixing members 313 provided on the vertical frame 311a are fixed to T-grooves tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 233. Furthermore, of the pair of vertical frames 311a that constitute the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 236. In this case, two fixing members 313 provided on the vertical frame 311a are fixed to T-grooves tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 236. Furthermore, a flat floor panel fp is attached to the top surface of the large floor frame 310C. This ensures that the top surface of the flat floor panel fp is positioned horizontally. As described above, the upper surface of the flat floor panel fp constitutes the prize display section E. Spare prizes P can be placed in the prize display section E. However, prizes P placed in the prize display section E cannot be acquired by the prize gripping section 410, based on a setting that restricts the movement range of the prize gripping section 410.

[0101] Furthermore, the prize placement mechanism 30 according to the fourth example is composed of a first extension base frame 240, a second extension base frame 240, a first small floor frame 310A, a second small floor frame 310A, a first medium floor frame 310B, and a second medium floor frame 310B. In the prize-winning game machine 1, one or more expansion base frames 240 are provided. Each expansion base frame 240 can constitute a base frame unit 20. Each extension base frame 240 has the same configuration as the base frame 237. That is, each extension base frame 240 is formed in a rectangular prism shape. A T-groove tg is provided on each of the four sides of each extension base frame 240. Each T-groove tg extends linearly along the longitudinal direction of the extension base frame 240. Each T-groove tg is provided from one end to the other in the longitudinal direction of the extension base frame 240. Each extension base frame 240 can be spanned (connected) between the base frames 237 of opposing pairs of individual lifting frames 231-236 from the six sets of individual lifting frames 231-236. As a result, each extension base frame 240 is positioned to extend along the left-right direction. Specifically, each extension base frame 240 can be spanned between the front end of the base frame 237 of the individual lifting frame 231 and the front end of the base frame 237 of the individual lifting frame 234. In addition, each extension base frame 240 can be spanned between the rear end of the base frame 237 of the individual lifting frame 231 and the rear end of the base frame 237 of the individual lifting frame 234. Furthermore, each extension base frame 240 can be spanned between the front end of the base frame 237 of the individual lifting frame 232 and the front end of the base frame 237 of the individual lifting frame 235. Additionally, each extension base frame 240 can be spanned between the rear end of the base frame 237 of the individual lifting frame 232 and the rear end of the base frame 237 of the individual lifting frame 235. Furthermore, each extension base frame 240 can be spanned between the front end of the base frame 237 of the individual lifting frame 233 and the front end of the base frame 237 of the individual lifting frame 236. Additionally, each extension base frame 240 can be spanned between the rear end of the base frame 237 of the individual lifting frame 233 and the rear end of the base frame 237 of the individual lifting frame 236. Here, connecting fittings (not shown) are fixed to each longitudinal end of each extension base frame 240. Each extension base frame 240 can be attached to the base frame 237 via the connecting fittings. In this case, the connecting fittings are provided with fixing members having the same configuration as the fixing member 313. Each extension base frame 240 can be attached to the base frame 237 by fixing the fixing members to the T-grooves tg of the base frame 237.

[0102] In the prize placement mechanism 30 according to the fourth example, the first extension base frame 240 is spanned between the front end of the base frame 237 of the individual lifting frame 231 and the front end of the base frame 237 of the individual lifting frame 234. As a result, the individual lifting frames 231 and 234 are integrally connected via the first extension base frame 240. Furthermore, the second extension base frame 240 is spanned between the rear end of the base frame 237 of the individual lifting frame 232 and the rear end of the base frame 237 of the individual lifting frame 235. In this way, the individual lifting frames 232 and 235 are integrally connected via the second extension base frame 240.

[0103] The first small floor frame 310A is attached to the upper side of the first extension base frame 240. This positions the first small floor frame 310A to extend upward from the upper side of the first extension base frame 240. In this case, the first small floor frame 310A is attached to the upper side of the first extension base frame 240 by fixing a fixing member 313 provided on the horizontal frame 311b to a T-groove tg provided on the upper side of the first extension base frame 240. The second small floor frame 310A is attached to the upper side of the second extension base frame 240. This positions the second small floor frame 310A so as to extend upward from the upper side of the second extension base frame 240. In this case, the second small floor frame 310A is attached to the upper side of the second extension base frame 240 by fixing two fixing members 313 provided on the vertical frame 311a to T-grooves tg provided on the upper side of the second extension base frame 240.

[0104] The first medium-sized floor frame 310B is attached to the first small floor frame 310A and the first extension base frame 240. Specifically, of the two fixing members 313 provided on the vertical frame 311a that constitutes the first medium-sized floor frame 310B, one fixing member 313 is fixed to a T-groove TG provided on the upper side surface of the vertical frame 311a of the first small floor frame 310A, and the other fixing member 313 is fixed to a T-groove tg provided on the rear side surface of the first extension base frame 240. As a result, the first medium-sized floor frame 310B is positioned with its upper surface tilted outward in the left-right direction. The second medium-sized floor frame 310B is attached to the second small floor frame 310A and the second extension base frame 240. Specifically, of the two fixing members 313 provided on the vertical frame 311a that constitutes the second medium-sized floor frame 310B, one fixing member 313 is fixed to a T-groove TG provided on the upper side surface of the horizontal frame 311b of the second small floor frame 310A, and the other fixing member 313 is fixed to a T-groove tg provided on the front side surface of the second extension base frame 240. As a result, the second medium-sized floor frame 310B is positioned with its upper surface tilted inward in the left-right direction.

[0105] A spherical part 333 is attached to the outer surface of the horizontal frame 311b that constitutes the first medium-sized floor frame 310B. The spherical part 333 is fixed to the T-groove TG provided on the outer surface of the horizontal frame 311b via the T-groove nut described above. The first prize hanging part C is formed at the spherical portion 333a of the spherical part 333. Here, the fixing position of the spherical part 333 can be changed (adjusted) as appropriate along the T-groove TG. A spherical part 333 is attached to the outer surface of the horizontal frame 311b that constitutes the second medium-sized floor frame 310B. The spherical part 333 is fixed to the T-groove TG provided on the outer surface of the horizontal frame 311b via the T-groove nut described above. The spherical portion 333a of the spherical part 333 constitutes the second prize hanging part D. Here, the fixing position of the spherical part 333 can be changed (adjusted) as appropriate along the T-groove TG.

[0106] In the prize placement mechanism 30 of the fourth example, the first medium-sized floor frame 310B and the second medium-sized floor frame 310B are attached to different individual lifting frames 231, 232, 234, and 235. This makes it possible to individually adjust the height of the first prize hanging section C and the second prize hanging section D. In other words, when adjusting the height of the first prize hanging section C, the height of the first prize hanging section C can be adjusted by raising and lowering the individual lifting frames 231 and 234 relative to the overall lifting frame 220. Furthermore, by changing (adjusting) the fixing position of the fixing member 313 of the first medium-sized floor frame 310B in the T-groove TG of the first small floor frame 310A, it is possible to change (adjust) the inclination angle of the spherical part 333. Furthermore, when adjusting the height of the second prize hanging section D, the height of the second prize hanging section D can be adjusted by raising and lowering the individual lifting frames 232 and 235 relative to the overall lifting frame 220. In addition, the tilt angle of the spherical part 333 can be changed (adjusted) by changing (adjusting) the fixing position of the fixing member 313 of the second medium-sized floor frame 310B in the T-groove TG of the second small floor frame 310A. This allows for adjustment of the relative positional relationship (height relationship) between the first prize hanging section C, the second prize hanging section D, and the prize display section E. Subsequently, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize gripping section 410 and each prize hanging section C, D can be adjusted all at once while maintaining the relative positional relationship (height relationship) between the first prize hanging section C, the second prize hanging section D, and the prize display section E. In other words, with the individual lifting lock mechanism 239 locking the lifting of each individual lifting frame 231 to 236 relative to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered relative to the foundation frame 210.

[0107] Based on the above, the prize distribution mechanism 30 for the fourth example is constructed. The prize placement mechanism 30 according to the fourth example comprises a prize placement area AE and an opening area OE within the game area GE. Specifically, prize hanging parts C and D are formed on the spherical portion 333a of each spherical part 333. Prizes P can be suspended from each prize hanging part C and D via D-rings dr. As a result, the prize placement area AE is formed below each prize hanging part C and D. Furthermore, the opening area OE is formed below the prizes P suspended from each prize hanging part C and D. In particular, in the game area GE, it becomes possible to place prizes P suspended above the opening area OE. Furthermore, in the prize placement mechanism 30 of the fourth example, the prize gripping part 410 can detach the D-ring dr, which is hooked onto each prize hanging part C, D, from the prize hanging parts C, D, thereby making it possible to obtain the prize P connected to the D-ring dr.

[0108] (Example 5) Next, we will explain the prize distribution mechanism 30 related to the fifth example. Figure 25 shows an example of the configuration of the prize distribution mechanism 30 according to the fifth example. As shown in Figure 25, the prize placement mechanism 30 according to the fifth example has a part (hereinafter referred to as the "prize support part") in the game area GE that is capable of supporting the prize P. In addition, a prize display part E is configured in the game area GE. In other words, the prize distribution mechanism 30 in the fifth example is composed of a large floor frame 310C. The large floor frame 310C is spanned between the individual lifting frame 233 located on the left frame unit 221 and the individual lifting frame 236 located on the right frame unit 222. Specifically, of the pair of vertical frames 311a that constitute the large floor frame 310C, one vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 233. In this case, two fixing members 313 provided on the vertical frame 311a are fixed to T-grooves tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 233. Furthermore, of the pair of vertical frames 311a that constitute the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 236. In this case, two fixing members 313 provided on the vertical frame 311a are fixed to T-grooves tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 236. Furthermore, a flat floor panel is attached to the top surface of the large floor frame 310C. This ensures that the top surface of the flat floor panel is positioned horizontally. As described above, the upper surface of the flat floor panel constitutes the prize display section E. Spare prizes P can be placed in the prize display section E. However, prizes P placed in the prize display section E cannot be acquired by the prize gripping section 410, based on a setting that restricts the movement range of the prize gripping section 410.

[0109] Furthermore, the prize placement mechanism 30 in the fifth example is configured to include a pair of flexible rods 340. A pair of flexible rods 340 are stretched between an individual lifting frame 232 located on the left frame unit 221 and an individual lifting frame 234 located on the right frame unit 222. Specifically, the socket portion 344 provided at one end of each flexible rod 340 is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 232. In this case, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 232. Furthermore, the socket portion 344 provided at the other end of each flexible rod 340 is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 234. In this case, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 234. In particular, the pair of flexible rods 340 are arranged at a predetermined interval and substantially parallel to each other, spanning between the base frames 237 constituting the individual lifting frame 232 and the base frames 237 constituting the individual lifting frame 234. Furthermore, the base frame 237 of the individual lifting frame 232 is positioned higher than the base frame 237 of the individual lifting frame 234. As a result, the pair of flexible rods 340 are positioned with one end facing backward relative to the other end, causing them to be inclined in the depth direction. Additionally, the pair of flexible rods 340 are positioned with one end facing higher relative to the other end, causing them to be inclined in the vertical direction. In this configuration, each flexible rod 340 has a rod portion 341 that is extendable and retractable. Furthermore, the rod portion 341 can be rotated (rotated circumferentially around the central axis of the rod portion 341 as the axis of rotation) and oscillated (the direction and angle in which the central axis of the rod portion 341 extends can be changed) relative to each socket portion 344. This makes it possible to position each flexible rod 340 at any desired position and angle. Consequently, each flexible rod 340 can be positioned at an angle in the depth direction and vertical direction.

[0110] In the prize placement mechanism 30 of the fifth example, the vertical tilt angle of each flexible rod 340 can be changed (adjusted) by raising and lowering the individual lifting frames 232 and 234 relative to the overall lifting frame 220. In this configuration, each flexible rod 340 has a rod portion 341 that is extendable and retractable. Furthermore, when the cam lever 344c is operated to the locked position, the rotation of the rod portion 341 relative to the socket portion 344 is locked, but the swinging of the rod portion 341 relative to the socket portion 344 is not locked. As a result, with the cam lever 344c operated to the locked position (with the rotation of the rod portion 341 relative to the socket portion 344 locked), the vertical tilt angle of each flexible rod 340 can be changed (adjusted) by raising and lowering the individual lifting frames 232 and 234 relative to the overall lifting frame 220. In this case, the rod portion 341 extends and retracts in accordance with (following) the raising and lowering of the individual lifting frames 232 and 234 relative to the overall lifting frame 220, and the angle of the rod portion 341 relative to each socket portion 344 changes. Furthermore, by changing (adjusting) the fixing position of the T-groove nut portion 345 of each flexible rod 340 in the T-groove tg of each base frame 237, it is possible to change (adjust) the inclination angle in the depth direction of each flexible rod 340. Subsequently, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize gripping section 410 and each flexible rod 340 can be adjusted all at once while maintaining the inclination angle of each flexible rod 340. In other words, with the individual lifting lock mechanism 239 locking the lifting of each individual lifting frame 231 to 236 relative to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered relative to the foundation frame 210.

[0111] Based on the above, the prize distribution mechanism 30 for the fifth example is constructed. The prize placement mechanism 30 according to the fifth example comprises a prize placement area AE and an opening area OE within the game area GE. Specifically, a prize support section is formed by a pair of flexible rods 340. The prize P can be supported by the pair of flexible rods 340 (prize support section). As a result, the prize placement area AE is formed on the pair of flexible rods 340. Furthermore, the opening area OE is formed below the pair of flexible rods 340. In particular, when arranging multiple prizes P on a pair of flexible rods 340, it becomes possible to arrange the positions of the multiple prizes P differently in the depth direction and the vertical direction. This makes it possible to arrange the multiple prizes P three-dimensionally. In the prize placement mechanism 30 of the fifth example, the prize gripping part 410 causes the prize P, which is supported by the prize support part, to fall from the prize support part, thereby making it possible to acquire the prize P.

[0112] (Example 6) Next, we will explain the prize distribution mechanism 30 related to the sixth example. Figure 26 shows an example of the configuration of the prize distribution mechanism 30 according to the sixth example. As shown in Figure 26, the prize placement mechanism 30 according to the sixth example has a prize support section in the game area GE. In other words, the prize placement mechanism 30 according to the sixth example is composed of a medium-sized floor frame 310B, a first flexible rod 340, and a second flexible rod 340. The medium-sized floor frame 310B is attached to the middle individual lifting frame 232, one of the three sets of individual lifting frames 231 to 233 included in the left frame unit 221. Specifically, the medium-sized floor frame 310B is attached to the inner surface of the base frame 237 of the individual lifting frame 232. This positions the medium-sized floor frame 310B so that it extends from the inner surface of the individual lifting frame 232 toward the game area GE. In this configuration, the medium-sized floor frame 310B is attached to the inner surface of the base frame 237 by fixing two fixing members 313, which are provided on one side of the medium-sized floor frame 310B, to T-grooves tg provided on the inner surface of the base frame 237. As a result, the medium-sized floor frame 310B is attached to the individual lifting frame 232 in a cantilevered manner. Additionally, a floor panel 320 is attached to the top surface of the medium-sized floor frame 310B.

[0113] The first flexible rod 340 is spanned between the vertical frame 311a of the medium-sized floor frame 310B and the individual lifting frame 234 located in the right-side frame unit 222. Specifically, the socket portion 344 provided at one end of the first flexible rod 340 is attached to the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. In this case, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove TG provided on the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. Furthermore, the socket portion 344 provided at the other end of the first flexible rod 340 is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 234. In this case, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 234. The second flexible rod 340 is spanned between the vertical frame 311a of the medium-sized floor frame 310B and the individual lifting frame 235 located in the right-side frame unit 222. Specifically, the socket portion 344 provided at one end of the second flexible rod 340 is attached to the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. In this case, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove TG provided on the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. Furthermore, the socket portion 344 provided at the other end of the second flexible rod 340 is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 235. In this case, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 235.

[0114] In particular, the first flexible rod 340 and the second flexible rod 340 are stretched between the medium-sized floor frame 310B and the individual lifting frames 234 and 235, so as to extend in different directions from each other. Here, the base frame 237 of individual lifting frame 234 is positioned lower than the base frame 237 of individual lifting frame 232. On the other hand, the base frame 237 of individual lifting frame 235 is positioned higher than the base frame 237 of individual lifting frame 232. As a result, the first flexible rod 340 is positioned with one end facing forward relative to the other end, causing it to be inclined in the depth direction. Additionally, the first flexible rod 340 is positioned with one end facing lower relative to the other end, causing it to be inclined in the vertical direction. Furthermore, the second flexible rod 340 is positioned so that one end is located further back from the other end, resulting in an inclined position in the depth direction. Additionally, the second flexible rod 340 is positioned so that one end is located higher than the other end, resulting in an inclined position in the vertical direction. In this configuration, each flexible rod 340 has a rod portion 341 that is extendable and retractable. Furthermore, the rod portion 341 can be rotated (rotated circumferentially around the central axis of the rod portion 341 as the axis of rotation) and oscillated (the direction and angle in which the central axis of the rod portion 341 extends can be changed) relative to each socket portion 344. This makes it possible to position each flexible rod 340 at any desired position and angle. Consequently, each flexible rod 340 can be positioned at an angle in the depth direction and vertical direction.

[0115] In the prize placement mechanism 30 of the sixth example, the vertical tilt angle of the first flexible rod 340 can be changed (adjusted) by raising and lowering the individual lifting frames 234 relative to the overall lifting frame 220. Furthermore, by raising and lowering the individual lifting frames 235 relative to the overall lifting frame 220, it is possible to change (adjust) the vertical tilt angle of the second flexible rod 340. At this time, in each flexible rod 340, the rod portion 341 is configured to be stretchable and contractible. Also, in each flexible rod 340, when the cam lever 344c is operated to the lock position, the rotation of the rod portion 341 with respect to the socket portion 344 is locked, but the swing of the rod portion 341 with respect to the socket portion 344 is not locked. Thus, for each flexible rod 340, with the cam lever 344c operated to the lock position (with the rotation of the rod portion 341 with respect to the socket portion 344 locked), by raising and lowering the individual lifting frames 234 and 235 with respect to the overall lifting frame 220, it is possible to change (adjust) the inclination angle in the vertical direction of each flexible rod 340. At this time, in accordance with (following) the raising and lowering of the individual lifting frames 234 and 235 with respect to the overall lifting frame 220, the rod portion 341 stretches and contracts, and the angle of the rod portion 341 with respect to each socket portion 344 changes. Also, by changing (adjusting) the fixing position of the T-groove nut portion 345 of the first flexible rod 340 in the T-groove tg of the base frame 237 of the individual lifting frame 234, it is possible to change (adjust) the inclination angle in the depth direction of the first flexible rod 340. Furthermore, by changing (adjusting) the fixing position of the T-groove nut portion 345 of the second flexible rod 340 in the T-groove tg of the base frame 237 of the individual lifting frame 235, it is possible to change (adjust) the inclination angle in the depth direction of the second flexible rod 340. After that, by raising and lowering the overall lifting frame 220 with respect to the base frame 210, the relative positional relationship (height relationship) between the prize gripping portion 410 and each flexible rod 340 can be adjusted collectively while maintaining the inclination angle of each flexible rod 340. That is, with the individual lifting lock mechanism 239 locking the raising and lowering of each individual lifting frame 23 1~236 with respect to the overall lifting frame 220, it is possible to raise and lower the overall lifting frame 220 with respect to the base frame 210.

[0116] Thus, the prize arrangement mechanism 30 according to the sixth example is configured. The prize arrangement mechanism 30 according to the sixth example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, a pair of flexible rods 340 constitutes a prize support part. And it is possible to support the prize P by the pair of flexible rods 340 (prize support part). At this time, the bottom surface of the prize P is supported by the first flexible rod 340, and the back surface of the prize P is supported by the second flexible rod 340. As a result, it is possible to arrange the prize P in a standing state. As described above, a prize arrangement area AE is constituted on the pair of flexible rods 340. Also, an opening area OE is constituted below the pair of flexible rods 340. And in the prize arrangement mechanism 30 according to the sixth example, the prize P supported by the prize support part can be obtained by dropping the prize P from the prize support part by the prize gripping part 410.

[0117] (Crane unit 40) Next, the configuration of the crane unit 40 will be described. The crane unit 40 includes a prize gripping part 410, a moving device 420 that moves the prize gripping part 410 in the horizontal direction, and a lifting device 430 that raises and lowers the prize gripping part 410. The prize gripping part 410 is attached to the bottom surface of the lifting device 430 via a support part 413 that can be expanded and contracted. The prize gripping part 410 includes a pair of arms 411 and an opening / closing device 412 that opens and closes the pair of arms 411. Each arm 411 is formed in a substantially L-shaped rod shape. A claw member 411a is attached to the lower end of each arm 411. The opening / closing device 412 includes an opening / closing motor m1 and an opening / closing mechanism (not shown). In the opening / closing device 412, by driving the opening / closing motor m1, the pair of arms 411 can be opened and closed via the opening / closing mechanism. And the prize gripping part 410 can grip the prize P by opening and closing the pair of arms 411.

[0118] The moving device 420 is composed of an X-direction rail Lx, a Y-direction rail Ly, an X-direction motor m2, and a Y-direction motor m3. The X-direction rail Lx is attached to the upper horizontal member 214a of the foundation frame 210. The X-direction rail Lx extends linearly along the left-right direction. The Y-direction rail Ly is attached to the X-direction rail Lx. The Y-direction rail Ly is slidable along the X-direction rail Lx. The Y-direction rail Ly extends linearly along the depth direction. The Y-direction rail Ly is moved along the X-direction rail Lx by driving the X-direction motor m2.

[0119] The lifting device 430 is mounted on the Y-direction rail Ly. The lifting device 430 is slidable along the Y-direction rail Ly. The lifting device 430 is moved along the Y-direction rail Ly by driving the Y-direction motor m3. The lifting device 430 includes a reel (not shown) capable of feeding out or winding up a wire, and a lifting motor m4 that drives the reel. The tip of the wire is attached to the prize gripping section 410. This allows the prize gripping section 410 to be lowered by driving the reel with the lifting motor m4 to feed out the wire. Conversely, the prize gripping section 410 can be raised by driving the reel with the lifting motor m4 to wind up the wire. As described above, the crane unit 40 can move the prize gripping section 410 in the left-right, depth, and up-down directions by driving the respective motors m2, m3, and m3. In addition, the pair of arms 411 can be opened and closed by driving the opening / closing motor m1.

[0120] (Control board 50) Next, the configuration of the control board 50 will be described. Figure 27 is a block diagram showing the configuration of the control board 50. As shown in Figure 27, the control board 50 is configured to include a control unit 51, a storage unit 52, and the like. The control unit 51 is composed of a microcomputer that includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc. Based on various detection signals input from the control panel 13 and program data stored in the memory unit 52, the control unit 51 executes the processing necessary for the progress of the prize-winning game. The memory unit 52 is composed of non-volatile memory and the like. The memory unit 52 stores program data necessary for the progress of the prize-winning game. Here, the prize-winning game device 1 is equipped with an X-position detection means 53 for detecting the position of the prize-grabbing part 410 in the X direction (left-right direction), a Y-position detection means 54 for detecting the position of the prize-grabbing part 410 in the Y direction (depth direction), a Z-position detection means 55 for detecting the position of the prize-grabbing part 410 in the Z direction (up-down direction), and so on. The control unit 51 receives detection signals output in response to the pressing of each operation button 16a, 16b, and detection signals output by each position detection means 53, 54, 55, etc.

[0121] When the control unit 51 detects that a coin has been inserted into the coin slot 14, it starts the prize-winning game. During the prize-winning game, the input of a detection signal from the first operation button 16a is first monitored. Then, in response to the input of the detection signal from the first operation button 16a, the X-direction motor m2 is driven, and the prize-grabbing unit 410 moves along the left-right direction. Next, the input of a detection signal from the second operation button 16b is monitored. Then, in response to the input of the detection signal from the second operation button 16b, the Y-direction motor m3 is driven, and the prize gripping unit 410 is moved along the depth direction. Then, once the prize gripping section 410 has finished moving along the depth direction, the lifting motor m4 is driven, and after the prize gripping section 410 has been lowered to a predetermined height, the opening / closing motor m1 is driven, and the pair of arms 411 are closed. After that, the prize gripping section 410 has been raised to a predetermined height, and then the prize gripping section 410 is moved to a predetermined position (opening area OE). At the predetermined position, the opening / closing motor m1 is driven, and the pair of arms 411 are opened. Afterward, the prize gripping unit 410 is moved to its home position, and the prize-winning game ends.

[0122] (modified version) Although embodiments of the present invention have been described above, various modifications can be made to the above embodiments. For example, in the above embodiment, the overall lifting frame 220 may be configured to be able to move along the depth direction relative to the base frame 210. For example, the base frame 210 includes a mechanism for moving the overall lifting frame 220 along the depth direction, and a locking mechanism that can lock the movement of the overall lifting frame 220 along the depth direction. Specifically, a member is provided to integrate a pair of left-side overall lifting guide rails 216a and 216b, and a member is provided to integrate a pair of right-side overall lifting guide rails 217a and 217b. Furthermore, a mechanism is provided to allow the integrated pair of left-side overall lifting guide rails 216a and 216b to move along the depth direction relative to the intermediate horizontal member 212b and the lower horizontal member 212c, and a mechanism is provided to allow the integrated pair of right-side overall lifting guide rails 217a and 217b to move along the depth direction relative to the intermediate horizontal member 213b and the lower horizontal member 213c. In addition, a locking mechanism similar to the overall lifting locking mechanism 218, or a latch mechanism, is provided. With this configuration, by releasing the lock mechanism, the six sets of individual lifting frames 231-236, which are mounted to the overall lifting frame 220 so as to be able to move up and down, can be pulled out towards the front of the base frame 210 all at once. This allows the operator to configure the prize placement mechanism 30 with the six sets of individual lifting frames 231-236 pulled out towards the front, thus simplifying the configuration of the prize placement mechanism 30. Then, after the configuration of the prize placement mechanism 30 is complete, the six sets of individual lifting frames 231 to 236 are pushed together toward the back of the base frame 210 to return to their original positions and locked in place by the locking mechanism.

[0123] Furthermore, in the above embodiment, three sets of individual lifting frames 231 to 233 are attached to the left frame unit 221. However, the left frame unit 221 may be configured to have one set of individual lifting frames attached. Alternatively, the left frame unit 221 may be configured to have four or more sets of individual lifting frames attached. Similarly, in the above embodiment, three sets of individual lifting frames 234 to 236 are attached to the right frame unit 222. However, the right frame unit 222 may be configured to have one set of individual lifting frames attached. Alternatively, the right frame unit 222 may be configured to have four or more sets of individual lifting frames attached.

[0124] Furthermore, in the above embodiment, the base frame 237 is formed in a rectangular prism shape. That is, the cross-section perpendicular to the longitudinal direction of the base frame 237 is rectangular. And, a T-groove tg is provided on each of the four sides of the base frame 237. However, the base frame 237 may be formed in other polygonal shapes such as triangular prisms, pentagonal prisms, or hexagonal prisms. That is, the cross-section of the base frame 237 perpendicular to the longitudinal direction may be a triangle, a pentagon, a hexagon, or other polygon. Furthermore, T-grooves tg may be provided on each side of the base frame 237. By adopting such a configuration, when the floor frames 310A, 310B, and 310C are attached to the base frame 237, the floor frames 310A, 310B, and 310C can be angled with respect to the horizontal plane.

[0125] Also, in the above embodiment, in the overall lifting frame 220, a T-groove may be provided. For example, T-grooves are provided on the inner side surfaces of the upper side frames 224a and 224b. At this time, the T-grooves are provided so as to extend along the upper side frames 224a and 224b. Also, the configuration of the T-grooves is the same as the configuration of each of the T-grooves tg and TG. That is, the shape of the cross section orthogonal to the longitudinal direction of each T-groove is the same as the shape of the cross section orthogonal to the longitudinal direction of each of the T-grooves tg and TG. In particular, the dimensions (opening width, bottom width, depth) of each T-groove are the same as the dimensions (opening width, bottom width, depth) of each of the T-grooves tg and TG. Alternatively, the base frame 237 may be attached to the upper surfaces of the upper side frames 224a and 224b. In such a configuration, in the base frame 237, a pair of through holes penetrating in the vertical direction are provided, and a pair of guide rods 238 provided on the individual lifting frames 231 to 236 are inserted into the pair of through holes.

[0126] Also, in the above embodiment, the floor frames 310A, 310B, and 310C are configured as substantially quadrangular frame bodies in plan view. However, the floor frames 310A, 310B, and 310C may be configured as frame bodies of other polygons such as substantially triangular, substantially pentagonal, and substantially hexagonal in plan view.

[0127] Also, in the above embodiment, the floor frames 310A, 310B, and 310C are configured as substantially quadrangular frame bodies (frame portions) in plan view. However, the floor frames 310A, 310B, and 310C may be configured as substantially lattice-shaped (ladder-shaped) frame bodies (frame portions) in plan view. For example, the floor frames 310A, 310B, and 310C may be constructed as a roughly grid-like (ladder-like) frame (frame section) consisting of a pair of horizontal frames 311b and three or more vertical frames 311a spanning between the pair of horizontal frames 311b. In this case, the three or more vertical frames 311a extend parallel to each other. In particular, in the large floor frame 310C, in addition to the vertical frames 311a that are spanned across each end in the longitudinal direction of the pair of horizontal frames 311b, the configuration may also include vertical frames 311a spanned across approximately the middle of the pair of horizontal frames 311b in the longitudinal direction. This configuration makes it possible to increase the number of locations where floor panels 320, flexible rods 340, etc., can be attached.

[0128] Furthermore, in the above embodiment, each frame 311a, 311b is formed in a rectangular prism shape. That is, the cross-section perpendicular to the longitudinal direction of each frame 311a, 311b is rectangular. And, a T-groove TG is provided on each of the four sides of each frame 311a, 311b. However, each frame 311a, 311b may be formed in other polygonal prism shapes such as triangular prisms, pentagonal prisms, or hexagonal prisms. That is, the cross-section of each frame 311a, 311b perpendicular to the longitudinal direction may be a triangle, a pentagon, a hexagon, or other polygon. Furthermore, T-grooves TG may be provided on each side of each frame 311a, 311b. By adopting this configuration, when the floor frames 310A, 310B, and 310C are attached to the base frame 237, it becomes possible to angle the floor frames 310A, 310B, and 310C with respect to the horizontal plane.

[0129] Furthermore, in the above embodiment, the floor panel 320 is attached to the upper surface of the floor frames 310A, 310B, and 310C by screw fastening. However, the floor panel 320 may also be configured to be attached to the upper surface of the floor frames 310A, 310B, and 310C by hook pieces (hook pieces / claw pieces). Specifically, multiple hooks are provided on the underside of the floor panel 320. Each hook is provided so as to extend downward from the underside of the floor panel 320. The lower end of each hook is bent outwards. Then, when attaching the floor panel 320 to the upper surfaces of the floor frames 310A, 310B, and 310C, the lower end of each hook is hooked into the T-grooves TG provided on the inner surfaces of the frames 311a and 311b of the floor frames 310A, 310B, and 310C. This makes it possible to fix the floor panel 320 to the upper surfaces of the floor frames 310A, 310B, and 310C. Alternatively, the floor panel 320 may be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by a one-touch joint (coupler). In this case, a fastener is used that includes a shaft, a plug portion provided at the lower end of the shaft, and a head portion provided at the upper end of the shaft. The shaft portion of the fastener is inserted through a hole provided on the upper surface of the floor panel 320. At this time, the head portion is positioned on the upper side of the floor panel 320, and the plug portion is positioned on the lower side of the floor panel 320. The plug portion is then inserted into a socket portion provided on the frames 311a and 311b, thereby locking (fixing) the plug portion within the socket portion. This fixes the floor panel 320 to the floor frames 310A, 310B, and 310C. The lock of the plug portion by the socket portion is released by operating a release ring provided on the socket portion. Alternatively, the floor panel 320 may be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by T-slot nuts having screw heads. In this case, a fastener is used that includes a shaft, a T-slot nut provided at the lower end of the shaft, and a screw head provided at the upper end of the shaft. The shaft of the fastener is inserted through a hole provided at the upper surface of the floor panel 320. At this time, the screw head is positioned on the upper side of the floor panel 320, and the T-slot nut is positioned on the lower side of the floor panel 320. After inserting the T-slot nut into the T-slot TG, the T-slot nut is fixed in the T-slot TG by rotating the screw head with a screwdriver or the like. Alternatively, the floor panel 320 may be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by threaded portions (bolt feet) provided on the lower surface of the floor panel 320. In this case, holes are provided in the frames 311a and 311b of the floor frames 310A, 310B, and 310C for inserting the threaded portions provided on the lower surface of the floor panel 320. The lower ends of the threaded portions that penetrate from the upper surface to the lower surface of the frames 311a and 311b through the holes are then fixed with wing nuts or the like, with a fixing plate in between.

[0130] Furthermore, in the above embodiment, the floor panel 320 is mounted on the upper surfaces of the floor frames 310A, 310B, and 310C. However, the floor panel 320 may be configured to be attached to at least one of the upper and lower surfaces of the floor frame 310A, 310B, or 310C.

[0131] Furthermore, in the above embodiment, the row spacing and column spacing of the multiple mounting portions 321 on the upper surface of the floor panel 320 are narrower than the width of the claw member 411a. This configuration prevents the claw member 411a from passing between two adjacent mounting portions 321 when floor parts are attached to them in each row or column. However, the upper surface of the floor panel 320 may be configured such that the row spacing and column spacing of the multiple mounting portions 321 are wider than the width of the claw member 411a. This allows the claw member 411a to pass between two adjacent mounting portions 321 when floor parts are attached to them in each row or column.

[0132] Furthermore, in the above embodiment, the floor frames 310A, 310B, and 310C and the floor panel 320 (or flat floor panel fp) are configured as separate components. However, the floor frames 310A, 310B, and 310C and the floor panel 320 (or flat floor panel fp) may be constructed as a single integrated component.

[0133] Furthermore, in the above embodiment, the floor panel 320 is formed in a substantially square, flat plate shape when viewed from above. However, the floor panel 320 may be configured in a three-dimensional shape. For example, the floor panel 320 may be configured in the shape of a square pyramid, a truncated square pyramid, or a triangular prism lying on its side. In such a configuration, multiple mounting parts 321 are provided on the surface (slope or top surface) of the floor panel 320.

[0134] Furthermore, in the above embodiment, a plurality of mounting portions 321 are configured on the upper surface of the floor panel 320. However, the floor panel 320 may be configured with multiple T-grooves on its upper surface. For example, the floor panel 320 may be configured with multiple T-grooves extending parallel to each other at predetermined intervals on its upper surface. Each T-groove extends linearly along one side of the floor panel 320. Each T-groove TG extends from one end to the other on one side of the floor panel 320. The configuration of each T-slot shall be the same as that of each T-slot tg and TG. That is, the shape of the cross-section perpendicular to the longitudinal direction of each T-slot shall be the same as the shape of the cross-section perpendicular to the longitudinal direction of each T-slot tg and TG. In particular, the dimensions of each T-slot (opening width, bottom width, depth) shall be the same as the dimensions of each T-slot tg and TG (opening width, bottom width, depth).

[0135] Furthermore, in the above embodiment, the cross-sections of the flexible rod 340, perpendicular to the longitudinal direction of each cylindrical body 341a, 341b, are teardrop-shaped. However, in the flexible rod 340, the cross-sections perpendicular to the longitudinal direction of each cylindrical body 341a, 341b can be changed as appropriate, such as to be circular, polygonal (triangle, quadrilateral, pentagon, hexagon), etc.

[0136] Furthermore, in the above embodiment, a T-groove nut portion 345 is provided on the bottom surface of the socket portion 344 (main body portion 344a) of the flexible rod 340. However, in the flexible rod 340, the T-groove nut portion 345 may not be provided on the bottom surface of the socket portion 344 (main body portion 344a). In this case, the flexible rod 340 is attached to the base frame 237 via a panel member attached to the base frame 237. That is, one or more holes are provided on the inner side surface of the panel member. The flexible rod 340 is then attached to the panel member by inserting the socket portion 344 into the hole. This makes it possible, for example, to position the flexible rod 340 so as to span between the hole in the panel member attached to the base frame 237 of the individual lifting frame 231 and the hole in the panel member attached to the base frame 237 of the individual lifting frame 234.

[0137] Furthermore, in the above embodiment, each mounting portion 321 is constructed by fitting a hexagonal nut into a recess (hole) provided on the upper surface of the floor panel 320. In addition, threaded portions are provided on the bottom surface of various floor parts (columnar parts 330, hemispherical parts 331, conical parts 332, spherical parts 333, etc.). The various floor parts are then attached to the mounting portion 321 by fitting the threaded portions into the mounting portion 321. However, it is also acceptable to configure the system so that various floor parts can be attached to the mounting section 321 using a one-touch joint (coupler). Specifically, each mounting section 321 is constructed by fitting a socket section into a recess (hole) provided on the upper surface of the floor panel 320. In addition, a plug section is provided on the bottom surface (lower end) of each floor part to fit into the socket section. When the plug section is inserted (fitted) into the socket section, the plug section is locked (fixed) within the socket section, and the floor parts are attached to the mounting section 321. Furthermore, by operating the release ring provided on the plug section, the lock of the plug section by the socket section is released, making it possible to remove the floor parts from the mounting section 321.

[0138] Furthermore, in the above embodiment, the floor panel 320 is configured to be attached to the floor frames 310A, 310B, and 310C. Specifically, the floor panel 320 is configured to be attached to the T-groove TG of the floor frames 310A, 310B, and 310C. However, the floor panel 320 may also be configured to be attached to the base frame 237. Specifically, the floor panel 320 may be configured to be attached to the T-groove tg of the base frame 237.

[0139] Furthermore, the above embodiment shows an example in which the locking mechanism according to the present invention is applied to the housing 10 of the prize-winning game device 1. However, the locking mechanism according to the present invention may be applied to other housings, such as showcase housings, as long as they have sliding doors.

[0140] (Operation of locking mechanisms 600 and 700) The locking mechanism 600,700 is located in a housing 10 which includes sliding doors 510,520 and a lower guide rail 530 that guides the opening and closing of the sliding doors 510,520, and locks the sliding doors 510,520. The locking mechanism 600,700 includes latch portions 620,720 that can be displaced between a locked position and an unlocked position via through holes 531,532 provided in the lower guide rail 530, biasing means SP1,SP2 that bias the latch portions 620,720 toward the locked position, latch holes 652,752 provided on the surface of the sliding doors 510,520 facing the lower guide rail 530, and an unlocking mechanism (cylinder locks 630,730 and link mechanisms 640,740) that can displace the latch portions 620,720 from the locked position to the unlocked position. Then, when the sliding doors 510 and 520 are slid in the closing direction, the latch portions 620 and 720, which are displaced from the locked position toward the unlocked position due to contact with the sliding doors 510 and 520, return to the locked position and are inserted into the latch holes 652 and 752, thereby locking the sliding doors 510 and 520. As a result, the locking mechanisms 600 and 700 allow the sliding doors 510 and 520 to be locked by sliding them in the closing direction. Therefore, locking the sliding doors 510 and 520 does not require opening or closing a key, and the effort required to lock the sliding doors 510 and 520 is reduced.

[0141] Furthermore, in the locking mechanisms 600 and 700, the latch portions 620 and 720 are tilted toward the closing direction of the sliding doors 510 and 520, causing them to be displaced from the locked position toward the unlocked position. As a result, in the locking mechanism 600, 700, the impact when the sliding door 510, 520, which slides in the closing direction, collides with the latch portion 620, 720 is suppressed compared to when the latch portion 620, 720 is displaced along the vertical direction, moving from the locked position towards the unlocked position, thereby suppressing damage to the latch portion 620, 720. Furthermore, in the locking mechanisms 600 and 700, the latches 620 and 720 can be kept in the unlocked position by operating the unlocking mechanisms (cylinder locks 630 and 730 and linkage mechanisms 640 and 740). This makes it possible to easily open the sliding doors 510 and 520 using the locking mechanisms 600 and 700. Furthermore, in the locking mechanisms 600 and 700, the housing 10 is equipped with a pair of sliding doors 510 and 520. The unlocking mechanism (cylinder locks 630 and 730 and link mechanisms 640 and 740) includes link mechanisms 640 and 740 that displace the latch parts 620 and 720 from the locked position to the unlocked position by rotating a key inserted into the keyholes ke1 and ke2 in the unlocking direction. The closing direction of one sliding door 510 and the other sliding door 520 are different. The unlocking direction is the same for the unlocking mechanism (cylinder lock 630 and link mechanism 640) corresponding to one sliding door 510 and the unlocking mechanism (cylinder lock 730 and link mechanism 740) corresponding to the other sliding door 520. In other words, in the locking mechanisms 600 and 700, the unlocking mechanism corresponding to one sliding door 510 (cylinder lock 630 and link mechanism 640) and the unlocking mechanism corresponding to the other sliding door 520 (cylinder lock 730 and link mechanism 740) have the same unlocking direction. This makes it possible to prevent misinterpretation of the unlocking direction for the unlocking mechanisms (cylinder locks 630 and 730 and link mechanisms 640 and 740) corresponding to each sliding door 510 and 520. Furthermore, in the locking mechanisms 600 and 700, the housing 10 is the housing of the prize-winning game device 1. This makes it possible for the locking mechanisms 600 and 700 to reduce the effort required to lock the sliding doors 510 and 520 of the housing 10 of the prize-winning game machine 1.
