[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, an example will be described in which the prize game device according to the present invention is applied to a prize game device 1 capable of executing a prize game. The "prize acquisition game" is a game in which the player (user) can acquire a prize P by operating the operation unit 16 to operate the prize holding unit 410 and cause a prize P placed in the prize placement area AE to drop into the opening area OE. The "prize P" may be either an item that is given to the player upon acquisition, or an item that is not given to the player upon acquisition and can be exchanged for another item (an item given to the player) after acquisition.

[0011] (Configuration of Prize Acquisition Game Device 1) First, the configuration of the prize game device 1 will be described. FIG. 1 is a perspective view showing the appearance of the prize game device 1. As shown in FIG. Here, in the example shown in FIG. 1, two prize winning game devices 1 are configured in one housing 10. That is, a common housing 10 is used for the two prize winning game devices 1. Note that one prize winning game device 1 may be configured in one housing 10. Also, three or more prize winning game devices 1 may be configured in one housing 10. In the following, the configuration of each prize game device 1 will be described.

[0012] As shown in Figure 1, the prize winning game device 1 includes a housing 10, a base frame unit 20 arranged within 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) arranged within the housing 10.

[0013] (Chassis 10) First, the configuration of the housing 10 will be described. The housing 10 is formed in a box shape. A game area (play area) GE in which a prize acquisition game is played is formed inside the housing 10. The housing 10 includes an upper housing 11 and a lower housing 12. The front, back, left side, and right side of the upper housing 11 are each made of a transparent plate material such as glass, acrylic plate, etc. This allows the player to view the game area GE configured inside the housing 10 from outside the housing 10. The front of the upper housing 11 is configured as a sliding door and can be opened and closed. This allows an operator (manager) to place and move prizes P and configure and change the prize placement mechanism 30 in the game area GE by opening the front of the upper housing 11.

[0014] A control panel 13 is provided on the front surface of the lower housing 12. The control panel 13 is provided with a coin insertion slot 14, a credit display unit 15, and an operation unit 16. A player can insert coins into the coin slot 14. By inserting coins into the coin slot 14, the player can acquire credits for playing a prize acquisition game. Note that an electronic money settlement device using a storage medium such as a prepaid card or credit card may be provided, allowing the player to acquire credits by settlement of electronic money. The remaining number of credits acquired by the player is displayed on the credit display section 15. That is, every time a credit is acquired by inserting a coin into the coin slot 14, the remaining number of credits displayed on the credit display section 15 increases. Also, every time a prize acquisition game is played, the remaining number of credits displayed on the credit display section 15 decreases.

[0015] The operation unit 16 accepts operations by the player. The operation unit 16 is configured to include a first operation button 16a and a second operation button 16b. Each of the operation buttons 16a, 16b can be pressed by the player. The first operation button 16a accepts an operation to move the prize holding portion 410 along the X direction (left-right direction) during the prize acquisition game. The second operation button 16b accepts an operation to move the prize holding portion 410 along the Y direction (depth direction) during the prize acquisition game. The operation unit 16 may be configured to include a third operation button that accepts an operation to move the prize gripping part 410 along the Z direction (up and down direction) during the prize acquisition game. Alternatively, the operation unit 16 may be configured to include a joystick that accepts an operation to move the prize gripping part 410 along the horizontal direction (left and right direction and depth direction) during the prize acquisition game, and a down button that accepts an operation to move the prize gripping part 410 along the Z direction (up and down direction).

[0016] In addition, a prize outlet 17 that communicates with the opening area OE is provided on the front side of the lower housing 12. Here, a prize slope (not shown) is arranged below the prize placement mechanism 30. The prize P that falls into the opening area OE is guided to the prize outlet 17 by the prize slope. This allows the player to obtain the prize P taken out from the prize outlet 17. An opening / closing door 19 is provided on the front side of the lower housing 12. Inside the opening / closing door 19, various control boards (such as the control board 50) are disposed.

Each of the right-side whole lifting guide rails 217a, 217b is spanned between the middle cross member 213b and the lower cross member 213c. As a result, each of the right-side whole lifting guide rails 217a, 217b is arranged with the guide grooves 217c extending in the up-down direction. The pair of right-side whole lifting guide rails 217a, 217b is arranged at a predetermined interval with the guide grooves 217c facing each other.

[0025] (Full lifting frame 220) FIG. 5 is an enlarged view showing the left frame unit 221. As shown in FIG. Here, FIG. 5 shows the base frame unit 20 with the left overall lifting / lowering guide rail 216a on the near side and the first individual lifting / lowering guide rail 227a omitted. The overall lifting frame 220 is configured to include 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 lattice shape. Specifically, the left frame unit 221 includes an upper frame 224a and a lower frame 225a arranged in parallel to each other. The left frame unit 221 also includes a pair of overall lift sliders 226a, 226b, a first individual lift guide rail 227a, a second individual lift guide rail 228a, and a third individual lift guide rail 229a, which are bridged between the upper frame 224a and the lower frame 225a.

[0026] Each of the whole lifting sliders 226a, 226b, 226c, 226d is made of a channel steel with a U-shaped cross section. The whole lifting sliders 226a, 226c on the front side are arranged to extend along the vertical direction with the open surface facing the rear side (with the back surface facing the front side). The upper ends of the whole lifting sliders 226a, 226c on the front side are fixed to the front ends of the upper frames 224a, 224b, and the lower ends of the whole lifting sliders 226a, 226c on the front side are fixed to the front ends of the lower frames 225a, 225b. On the other hand, the whole lifting sliders 226b, 226d on the rear side are arranged to extend along the vertical direction with the open surface facing the front side (with the back surface facing the rear side). The upper ends of the rear-side overall lifting / lowering sliders 226b, 226d are fixed to the rear ends of the upper frames 224a, 224b, and the lower ends of the rear-side overall lifting / lowering sliders 226b, 226d are fixed to the rear ends of the lower frames 225a, 225b. As shown in Fig. 5, a pair of guide rollers gr is provided on the back of each of the entire lifting sliders 226a, 226b, 226c, and 226d. The guide rollers gr provided on the rear side of the entire lifting sliders 226b and 226d are not shown. The pair of guide rollers gr are provided at the lower ends of the entire lifting sliders 226a, 226b, 226c, and 226d so as to be aligned at a predetermined interval in the vertical direction. Each guide roller gr is configured to be freely rotatable around a rotation shaft (not shown) extending in the depth direction. Additionally, a plurality of lock holes rh (see FIG. 5) are provided on the rear surface of the front whole lift sliders 226a, 226c. The plurality of lock holes rh are provided above the pair of guide rollers gr. The plurality of lock holes rh are provided so as to be aligned at predetermined intervals in the vertical direction. Each lock hole rh is a circular through hole.

[0027] Each of the individual lifting / lowering guide rails 227a, 227b, 228a, 228b, 229a, and 229b is made of a channel steel (channel material) having a U-shaped cross section. Each of the first individual lifting / lowering guide rails 227a and 227b is arranged to extend along the vertical direction with the open surface facing the front side (with the back surface facing the back side). Each of the second individual lifting / lowering guide rails 228a and 228b is arranged to extend along the vertical direction with the open surface facing the front side (with the back surface facing the back side). Each of the third individual lifting / lowering guide rails 229a and 229b is arranged to extend along the vertical direction with the open surface facing the back side (with the back surface facing the front side). The upper end of each of the individual lifting guide rails 227a, 228a, and 229a is fixed to the upper frame 224a, and the lower end of each of the individual lifting guide rails 227a, 228a, and 229a is 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. In addition, the first individual lifting guide rail 227a, the second individual lifting guide rail 228a, and the third individual lifting guide rail 229a are arranged so as to be aligned at a predetermined interval along the depth direction. The upper end of each of the individual lifting guide rails 227b, 228b, and 229b is fixed to the upper frame 224b, and the lower end of each of the individual lifting guide rails 227b, 228b, and 229b is 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. In addition, the first individual lifting guide rail 227b, the second individual lifting guide rail 228b, and the third individual lifting guide rail 229b are arranged so as to be aligned at a predetermined interval along the depth direction. A plurality of lock holes RH (see FIG. 5) are provided on the back surface of each of the individual lift guide rails 227a, 227b, 228a, 228b, 229a, and 229b. The lock holes RH are arranged at predetermined intervals along the vertical direction. Each lock hole RH is a circular through hole.

[0028] The connecting frame 223 is configured with a U-shaped cross section and is made of channel steel (channel material). The connecting frame 223 is arranged so as to extend in the left-right direction with the open surface facing the front side (with the back surface facing the back side). 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 top frame 224a. Also, the right end of the connecting frame 223 is fixed to the rear end of the top 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 the connecting frame 223.

[0029] The entire lifting frame 220 is attached to the base frame 210 so as to be movable up and down. Specifically, the left frame unit 221 is supported (held) by a pair of left whole lifting guide rails 216a, 216b so that it can be raised and lowered. That is, the two guide rollers gr of the front whole lifting slider 226a are disposed in the guide groove 216c of the left whole lifting guide rail 216a. This allows the front whole lifting slider 226a to slide up and down along the left whole lifting guide rail 216a (guide groove 216c). The two guide rollers gr of the rear whole lift slider 226b are disposed in the guide groove 216c of the left whole lift guide rail 216b. This allows the rear whole lift slider 226b to slide up and down along the left whole lift guide rail 216b (guide groove 216c). Similarly, the right frame unit 222 is supported (held) by a pair of right whole lifting guide rails 217a, 217b so as to be movable up and down. That is, the two guide rollers gr of the front whole lifting slider 226c are disposed in the guide groove 217c of the right whole lifting guide rail 217a. This allows the front whole lifting slider 226c to slide up and down along the right whole lifting guide rail 217a (guide groove 217c). The two guide rollers gr of the rear whole lift slider 226d are disposed in the guide groove 217c of the right whole lift guide rail 217b. This allows the rear whole lift slider 226d to slide up and down along the right whole lift guide rail 217b (guide groove 217c). As described above, the entire lifting frame 220 is attached to the base frame 210 so as to be movable up and down.

[0030] Here, the base frame 210 is configured to include a pair of overall lifting / lowering lock mechanisms 218 (a left overall lifting / lowering lock mechanism 218 and a right overall lifting / lowering lock mechanism 218). The pair of overall lifting / lowering lock mechanisms 218 make it possible to lock (fix) the lifting / lowering of the overall lifting frame 220 relative to the base frame 210. The left overall lift lock mechanism 218 is disposed at the upper end of the left overall lift guide rail 216a. The right overall lift lock mechanism 218 is disposed at the upper end of the right overall lift guide rail 217a. The right overall lift lock mechanism 218 is not shown. Each whole lift lock mechanism 218 includes an operating lever 218a and a lock shaft 218b. Each operating lever 218a can be operated (displaced) to a locked position or an unlocked position. Each lock shaft 218b is formed in a cylindrical shape and is disposed so as to extend along the depth direction. When each operating lever 218a is operated to the locked position, the lock shaft 218b protrudes toward the back side via a link mechanism (not shown). On the other hand, when each operating lever 218a is operated to the unlocked position, the lock shaft 218b retracts toward the front side via the link mechanism.

[0031] In the left-side whole lift lock mechanism 218, when the operating lever 218a is operated to the lock position, the lock shaft 218b is inserted into one of the lock holes rh provided in the front-side whole lift slider 226a, thereby locking the front-side whole lift slider 226a from sliding relative to the left-side whole lift guide rail 216a. Similarly, in the right-side whole lift lock mechanism 218, when the operating lever 218a is operated to the lock position, the lock shaft 218b is inserted into one of the lock holes rh provided in the front-side whole lift slider 226c, thereby locking the front-side whole lift slider 226c from sliding relative to the right-side whole lift guide rail 217a. This locks the overall lifting frame 220 from rising or falling relative to the base frame 210, making it impossible for the overall lifting frame 220 to rise or fall 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 of the overall lifting sliders 226a, 226c is provided with a plurality of lock holes rh along the vertical direction. This makes it possible to lock the overall lifting frame 220 at any height by selecting or changing the lock holes rh into which each lock shaft 218b is inserted, as shown in Figures 2 and 4. On the other hand, in the left-side whole lift lock mechanism 218, when the operating lever 218a is operated to the release position, the lock shaft 218b is removed from the lock hole rh provided in the front-side whole lift slider 226a, thereby releasing the lock of the front-side whole lift slider 226a from the left-side whole lift guide rail 216a. Similarly, in the right-side whole lift lock mechanism 218, when the operating lever 218a is operated to the release position, the lock shaft 218b is removed from the lock hole rh provided in the front-side whole lift slider 226c, thereby releasing the lock of the front-side whole lift slider 226c from the right-side whole lift guide rail 217a. This releases the lock of the entire lifting frame 220 from the base frame 210, allowing the entire lifting frame 220 to be raised and lowered relative to the base frame 210.

[0032] In addition, a pair of damper devices da that assist the elevation and lowering of the entire lifting frame 220 relative to the base frame 210 are arranged on the base 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 cross members 212c, 213c, and the tip of the shell case is supported by the lower frames 225a, 225b via a link mechanism. This allows the operator to easily raise and lower the overall lifting frame 220. That is, the pair of damper devices da pressurizes the overall lifting frame 220 upward relative to the base frame 210. This makes it possible to raise and lower the overall lifting frame 220 by adjusting the force (weight) that holds down the overall lifting frame 220, without the need to manually lift the overall lifting frame 220 when adjusting the height of the overall lifting frame 220. This makes it easy to raise and lower the overall lifting frame 220, maintain its height, lock it, and so on. In particular, it is possible to prevent the overall lifting frame 220 from suddenly falling when the lock of the overall lifting frame 220 by the pair of overall lifting lock mechanisms 218 is released.

[0033] (Individual lifting frames 231-236) FIG. 6 is a cross-sectional view of the base frame 237. Here, FIG. 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 of the individual lifting frames 231 to 236 includes a base frame 237, a pair of guide rods 238, and an individual lifting slider 238a. The base frame 237 is formed in a quadrangular prism shape. The base frame 237 is disposed so as to extend along the depth direction. In the following description, of the four sides of the base frame 237, the upper side is referred to as the "upper side", the lower side is referred to as the "lower side", and the side on the inside (the side facing the game area GE) is referred to as the "inner side". As shown in Fig. 6, a T-slot tg is provided on at least the inner side of the four side surfaces of the base frame 237. In this embodiment, the T-slot tg is provided on the inner side and the upper side of the four side surfaces of the base frame 237. In the example shown in Fig. 6, the T-slot tg is provided on each of the four side surfaces of the base frame 237. Each T-slot tg extends linearly along the longitudinal direction (the direction in which the base frame 237 extends) of the base frame 237. Each T-slot tg is provided from one end of the base frame 237 in the longitudinal direction to the other end. Each guide rod 238 is formed in a cylindrical 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 is provided so as to be aligned at a predetermined interval along the longitudinal direction of the base frame 237. The individual lift slider 238a is made of a channel steel (channel material) having a U-shaped cross section. The individual lift slider 238a is fixed to the lower end of one of the guide rods 238. The individual lift slider 238a is arranged to extend in the up-down direction. The width of the individual lift slider 238a is narrower than the width of each of the individual lift guide rails 227a, 227b, 228a, 228b, 229a, and 229b.

[0034] In this embodiment, three sets of individual lifting frames 231-233 are attached to the left frame unit 221. The three sets of individual lifting frames 231-233 are arranged to be lined up at predetermined intervals along the depth direction. Each of the individual lifting frames 231-233 is attached to the left frame unit 221 so as to be able to rise and fall. In particular, the three sets of individual lifting frames 231-233 can be raised and lowered individually. Specifically, among the three sets of individual lifting frames 231-233, the individual lifting frame 231 on the near side is supported (held) by the left frame unit 221 so as to be able to rise and fall. That is, the individual lifting frame 231 is attached to the left frame unit 221 by inserting a pair of guide rods 238 into guide holes gh provided in the upper frame 224a and disposing the individual lifting slider 238a in the first individual lifting guide rail 227a. Each guide rod 238 is slidable in the up-down direction relative to the guide hole gh through which the guide rod 238 is inserted. The individual lifting slider 238a is slidable in the up-down direction along the first individual lifting guide rail 227a. This allows the individual lifting frame 231 to rise and fall relative to the left frame unit 221. In particular, the base frame 237 included in the individual lifting frame 231 is capable of rising and lowering relative to the left frame unit 221. Among the three sets of individual lifting frames 231 to 233, the intermediate individual lifting frame 232 is supported (held) by the left frame unit 221 so as to be able to rise and fall. That is, the individual lifting frame 232 is attached to the left frame unit 221 by inserting a pair of guide rods 238 into guide holes gh provided in the upper frame 224a and disposing the individual lifting slider 238a in the second individual lifting guide rail 228a. Each guide rod 238 is slidable in the up-down direction relative to the guide hole gh through which the guide rod 238 is inserted. The individual lifting slider 238a is slidable in the up-down direction along the second individual lifting guide rail 228a. This allows the individual lifting frame 232 to rise and fall relative to the left frame unit 221. In particular, the base frame 237 included in the individual lifting frame 232 is slidable in the up-down direction relative to the left frame unit 221. Among the three sets of individual lifting frames 231 to 233, the individual lifting frame 233 at the rear side is supported (held) by the left frame unit 221 so as to be able to rise and fall. That is, the individual lifting frame 233 is attached to the left frame unit 221 by inserting a pair of guide rods 238 into guide holes gh provided in the upper frame 224a and disposing the individual lifting slider 238a in the third individual lifting guide rail 229a. Each guide rod 238 is slidable along the vertical direction with respect to the guide hole gh through which the guide rod 238 is inserted. Also, the individual lifting slider 238a is slidable along the third individual lifting guide rail 229a in the vertical direction. This allows the individual lifting frame 233 to rise and fall relative to the left frame unit 221. In particular, the base frame 237 included in the individual lifting frame 233 is slidable relative to the left frame unit 221.

[0035] 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 to be lined up at predetermined intervals along the depth direction. Each of the individual lifting frames 234-236 is attached to the right frame unit 222 so as to be able to rise and fall. In particular, the three sets of individual lifting frames 234-236 can be raised and lowered individually. Specifically, among the three sets of individual lifting frames 234-236, the individual lifting frame 234 on the near side is supported (held) by the right frame unit 222 so as to be able to rise and fall. That is, the individual lifting frame 234 is attached to the right frame unit 222 by inserting a pair of guide rods 238 into guide holes gh provided in the upper frame 224b and disposing the individual lifting slider 238a in the first individual lifting guide rail 227b. Each guide rod 238 is slidable in the vertical direction relative to the guide hole gh through which the guide rod 238 is inserted. The individual lifting slider 238a is slidable in the vertical direction along the first individual lifting guide rail 227b. This allows the individual lifting frame 234 to rise and fall relative to the right frame unit 222. In particular, the base frame 237 included in the individual lifting frame 234 is capable of being raised and lowered relative to the right frame unit 222. Among the three sets of individual lifting frames 234 to 236, the intermediate individual lifting frame 235 is supported (held) by the right frame unit 222 so as to be able to rise and fall. That is, the individual lifting frame 235 is attached to the right frame unit 222 by inserting a pair of guide rods 238 into guide holes gh provided in the upper frame 224b and disposing the individual lifting slider 238a in the second individual lifting guide rail 228b. Each guide rod 238 is slidable in the vertical direction relative to the guide hole gh through which the guide rod 238 is inserted. The individual lifting slider 238a is slidable in the vertical direction along the second individual lifting guide rail 228b. This allows the individual lifting frame 235 to rise and fall relative to the right frame unit 222. In particular, the base frame 237 included in the individual lifting frame 235 is slidable in the vertical direction relative to the right frame unit 222. Among the three sets of individual lifting frames 234 to 236, the individual lifting frame 236 at the rear side is supported (held) by the right frame unit 222 so as to be able to rise and fall. That is, the individual lifting frame 236 is attached to the right frame unit 222 by inserting a pair of guide rods 238 into guide holes gh provided in the upper frame 224b and disposing the individual lifting slider 238a in the third individual lifting guide rail 229b. Each guide rod 238 is slidable in the vertical direction relative to the guide hole gh through which the guide rod 238 is inserted. The individual lifting slider 238a is slidable in the vertical direction along the third individual lifting guide rail 229b. This allows the individual lifting frame 236 to rise and fall relative to the right frame unit 222. In particular, the base frame 237 included in the individual lifting frame 236 is slidable in the vertical direction relative to the right frame unit 222. As described above, each of the individual lifting frames 231 to 236 is attached to the overall lifting frame 220 so as to be able to rise and fall individually.

[0036] Here, each of the individual lifting frames 231-236 is configured to include an individual lifting / lowering lock mechanism 239. The individual lifting / lowering lock mechanism 239 provided in each of the individual lifting / lowering frames 231-236 makes it possible to lock (fix / maintain) the lifting / lowering of the individual lifting / lowering frames 231-236 relative to the general lifting frame 220. Each individual lift lock mechanism 239 includes an operation button 239a and a lock shaft 239b. The operation button 239a is attached to 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 so as to be disposed at the locked position. The operation button 239a can be operated from the locked position to the unlocked position by being pressed by an operator. The lock shaft 239b is attached to the individual lift-up slider 238a. The lock shaft 239b is formed in a cylindrical shape and is arranged to extend along the depth direction. When the operation button 239a is in the lock position, the lock shaft 239b protrudes outward from the back surface of the individual lift-up slider 238a through a through hole provided in the individual lift-up slider 238a. On the other hand, when the operation button 239a is operated to the release state, the lock shaft 239b retracts into the inside of the back surface of the individual lift-up slider 238a.

[0037] In the individual lifting / lowering lock mechanism 239 provided in the individual lifting / lowering frame 231, when the operation button 239a is placed in the lock position, the lock shaft 239b is inserted into one of the lock holes RH provided in the first individual lifting / lowering guide rail 227a. This locks the sliding of the individual lifting / lowering slider 238a relative to the first individual lifting / lowering guide rail 227a. As a result, the individual lifting frame 231 is locked from rising or falling relative to the overall lifting frame 220, and the individual lifting frame 231 cannot rise or fall relative to the overall lifting frame 220. That is, 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 a plurality of lock holes RH along the up-down direction. As a result, as shown in Figures 2 and 3, by selecting or changing the lock hole RH into which the lock shaft 239b is inserted, it is possible to lock the individual lifting frame 231 at any height. On the other hand, in the individual lift-up / lowering lock mechanism 239 provided in the individual lift-up / lowering frame 231, when the operation button 239a is operated to the release position, the lock shaft 239b is removed from the lock hole RH provided in the first individual lift-up / lowering guide rail 227a, thereby releasing the lock of the individual lift-up / lowering slider 238a from the first individual lift-up / lowering guide rail 227a. This releases the lock of the individual lifting frames 231 from the overall lifting frame 220, allowing the individual lifting frames 231 to be raised and lowered relative to the overall lifting frame 220.

[0038] Here, with respect to the other individual lifting frames 232-233, based on the same principle as the individual lifting frame 231, it is possible for the other individual lifting frames 232-236 to be lifted and lowered, and for the other individual lifting frames 232-236 to be locked at any height. At this time, the individual lifting / lowering lock mechanism 239 provided on the individual lifting / lowering frame 232 can lock the lifting / lowering of the individual lifting / lowering frame 232 relative to the overall lifting / lowering frame 220 by locking the sliding of the individual lifting / lowering slider 238a relative to the second individual lifting / lowering guide rail 228a. On the other hand, the individual lifting / lowering lock mechanism 239 provided on the individual lifting / lowering frame 233 is capable of locking the lifting / lowering of the individual lifting / lowering frame 233 relative to the overall lifting / lowering frame 220 by locking the sliding of the individual lifting / lowering slider 238a relative to the third individual lifting / lowering guide rail 229a. On the other hand, the individual lifting / lowering lock mechanism 239 provided on the individual lifting / lowering frame 234 is capable of locking the lifting / lowering of the individual lifting / lowering frame 234 relative to the overall lifting / lowering frame 220 by locking the sliding of the individual lifting / lowering slider 238a relative to the first individual lifting / lowering guide rail 227b. On the other hand, the individual lifting / lowering lock mechanism 239 provided on the individual lifting / lowering frame 235 is capable of locking the lifting / lowering of the individual lifting / lowering frame 235 relative to the overall lifting / lowering frame 220 by locking the sliding of the individual lifting / lowering slider 238a relative to the second individual lifting / lowering guide rail 228b. On the other hand, the individual lifting / lowering lock mechanism 239 provided on the individual lifting / lowering frame 236 is capable of locking the lifting / lowering of the individual lifting / lowering frame 236 relative to the overall lifting / lowering frame 220 by locking the sliding of the individual lifting / lowering slider 238a relative to the third individual lifting / lowering guide rail 229b.

[0039] (Prize placement mechanism 30) Next, the configuration of the prize placement mechanism 30 will be described. FIG. 7 is a perspective view showing an example of a prize placement mechanism 30 attached to the base frame unit 20. As shown in FIG. Within the cabinet 10 (particularly within the area surrounded by the base frame unit 20), a game area GE in which a prize acquisition game is played is configured. The prize placement mechanism 30 is a mechanism for placing prizes P within the game area GE. That is, the prizes P are placed within the game area GE by the prize placement mechanism 30. At this time, as the manner of placement, various manners such as placing, hanging, clamping, etc. can be selected according to the configuration of the prize placement mechanism 30. In particular, in this embodiment, the prize placement mechanism 30 forms a prize placement area AE and an opening area OE within the game area GE. The "prize placement area AE" is the area where prizes P are placed. The "opening area OE" is an area into which a prize P can be won by dropping the prize P.

[0040] 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 suspended between the individual lifting frame 231 and the individual lifting frame 234. Here, the configuration of the prize placing mechanism 30 shown in FIG. 7 is just one example, and as will be described later, the prize placing mechanism 30 can have various configurations. The prize placement mechanism 30 is formed by one component or by combining multiple components. In this embodiment, one or more small floor frames 310A, one or more medium 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. are prepared as components constituting the prize arrangement mechanism 30. The prize arrangement mechanism 30 is constructed by combining one or more of these components. Each component will be described below.

[0041] (Floor frames 310A, 310B, 310C) Fig. 8 is a perspective view showing the medium-sized floor frame 310B. Fig. 9 is a cross-sectional view taken along the line AA shown in Fig. 8. Fig. 10 is a perspective view showing the small-sized floor frame 310A and the medium-sized floor frame 310B in a connected state. The small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C have the same basic configuration. The small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C are different in size. Specifically, the small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C have different longitudinal dimensions (lengths) of the horizontal frames 311b described below. As shown in FIG. 8, the floor frames 310A, 310B, and 310C include 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 of the frames 311a and 311b is formed in a rectangular prism shape. In the following description, when the floor frames 310A, 310B, and 310C are placed on a flat surface, the upper side of each of the frames 311a and 311b is referred to as the "upper side", the lower side is referred to as the "lower side", the inner side (the side toward the center of the floor frames 310A, 310B, and 310C) is referred to as the "inner side", and the outer side (the side opposite the center of the floor frames 310A, 310B, and 310C) is referred to as the "outer side". 8 and 9 show a state in which a T-slot nut (T-slot nut) described later is inserted into the T-slot TG provided on the upper side of each horizontal frame 311b. Therefore, when the T-slot nut (T-slot nut) is removed from each T-slot TG, the T-slot TG is in the same state as other T-slots TG (such as the T-slot TG provided on the upper side of each vertical frame 311a). Here, the T-slot nut is a member used to attach the floor panel 320, various floor parts, etc. to each floor frame 310A, 310B, 310C. FIG. 8 and FIG. 9 show an example in which a T-slot nut having a dimension approximately the same as the longitudinal dimension of the T-slot TG is used. However, it is possible to use various T-slot nuts having a dimension shorter than the longitudinal dimension of the T-slot TG as the T-slot nut. As shown in Fig. 9, at least the outer side of each of the four side surfaces of each of the frames 311a and 311b is provided with a T-slot TG. In this embodiment, the outer side, upper side, and lower side of each of the four side surfaces of each of the frames 311a and 311b are provided with the T-slot TG. In the example shown in Fig. 9, the T-slot TG is provided in each of the four side surfaces of each of the frames 311a and 311b. Each T-slot TG extends linearly along the longitudinal direction of each frame 311a, 311b (the direction in which each frame 311a, 311b extends). Each T-slot TG is provided from one end of each frame 311a, 311b in the longitudinal direction to the other end of each frame 311a, 311b. Here, the configuration of each T-groove TG is the same as the configuration of each T-groove tg. That is, the shape of a cross section perpendicular to the longitudinal direction of each T-groove TG is the same as the shape of a 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 the same as the dimensions (opening width, bottom width, depth) of each T-groove tg.

[0042] Each corner bracket 312 includes 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 state where they are arranged at a substantially right angle. Each fixing member 313 includes a cylindrical shaft portion 313a, an operating portion 313b fixed to one end of the shaft portion 313a, and a T-slot nut portion (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 coaxially arranged. 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-groove nut portion 313c is formed in a substantially rectangular plate shape in a plan view. In particular, the longitudinal dimension (length) of the T-groove nut portion 313c is greater than the width of each of the T-grooves TG, tg. On the other hand, the longitudinal dimension (width) of the T-groove nut portion 313c in a direction perpendicular to the longitudinal direction is smaller than the width of each of the T-grooves TG, tg.

[0043] The floor frames 310A, 310B, and 310C are configured by connecting four frames 311a and 311b in an endless (annular) shape with four corner brackets 312. This makes the floor frames 310A, 310B, and 310C into a substantially rectangular frame body (frame portion) in a plan view. Further, one or more fixing members 313 are attached to each of the frames 311a, 311b. Specifically, each of the frames 311a, 311b is provided with a through hole h penetrating between the bottom surface of the T-groove TG provided on the outer surface and the bottom surface of the T-groove TG provided on the inner surface. In this embodiment, each of the frames 311a, 311b is provided with one or more through holes h. Then, 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. As a result, the shaft portion 313a of each fixing member 313 penetrates the frames 311a, 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 operation portion 313b of each fixing member 313 is arranged so as to protrude inward from the inner surface of the frames 311a, 311b. That is, the operation portion 313b of each fixing member 313 is arranged inside the inner surface of the frames 311a, 311b. On the other hand, the T-groove nut portion 313c of each fixing member 313 is arranged so as to protrude outward from the outer surface of the frames 311a, 311b. That is, the T-groove nut portion 313c of each fixing member 313 is arranged outside the outer surface of the frames 311a, 311b.

[0044] In the small-sized floor frame 310A, the medium-sized floor frame 310B, and the large-sized floor frame 310C, the horizontal frames 311b have different longitudinal dimensions (lengths), but the vertical frames 311a have the same longitudinal dimensions (lengths). In the medium-sized floor frame 310B, the four frames 311a, 311b have the same longitudinal dimensions. This makes the medium-sized floor frame 310B a substantially square frame in a plan view. In the medium-sized floor frame 310B, two fixing members 313 are attached to each of the frames 311a, 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. This makes the small floor frame 310A a vertically long, approximately rectangular frame in a plan view. 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. This makes the large floor frame 310C a horizontally elongated, approximately rectangular frame in a plan view. In particular, the width of the large floor frame 310C is three times that of the medium floor frame 310B. In the large floor frame 310C, two fixing members 313 are attached to each of the frames 311a and 311b.

[0045] Each of the floor frames 310A, 310B, and 310C can be attached to the upper side or inner side of the base frame 237. Each of the floor frames 310A, 310B, and 310C can be attached to the upper side or inner side of the base frame 237 via a fixing member 313. That is, when attaching the floor frames 310A, 310B, 310C to the upper or inner surface of the base frame 237, first, the outer surface of one of the four frames 311a, 311b (hereinafter referred to as the "fixed frame") that make up the floor frames 310A, 310B, 310C is positioned facing the upper or inner surface of the base frame 237 (hereinafter referred to as the "fixed surface"). Next, the T-slot nut portion 313c of each fixing member 313 provided on the fixing frame is inserted into the T-slot tg provided on the fixing surface. At this time, the operating portion 313b of each fixing member 313 is rotated to align the longitudinal direction of the T-slot nut portion 313c with the longitudinal direction of the T-slot tg, thereby making it possible to insert the T-slot nut portion 313c into the T-slot tg. Next, the operating portion 313b of each fixing member 313 is rotated to rotate the T-slot nut portion 313c by 90° in a predetermined direction. Then, in the T-slot tg, the T-slot nut portion 313c is displaced from a state parallel to the T-slot tg (released state) to a state perpendicular to the T-slot tg (fixed state). As a result, the T-slot nut portion 313c of each fixing member 313 is fixed in the T-slot tg. This causes the fixing frame to be fixed to the base frame 237 with the outer surface of the fixing frame and the fixing surface in close contact with each other. In particular, when the T-slot nut portion 313c is displaced to a state (fixed state) perpendicular to the T-slot tg, the position of the T-slot nut portion 313c is fixed within the T-slot tg. This makes it impossible to change the fixed position of the fixing member 313 in the T-slot tg. On the other hand, when the T-slot nut portion 313c is displaced to a state (released state) parallel to the T-slot tg, the fixed position of the T-slot nut portion 313c within the T-slot tg is released. This makes it possible to change the fixed position of the fixing member 313 in the T-slot tg. In this manner, the floor frames 310A, 310B, and 310C are attached to the fixing surface of the base frame 237.

[0046] In particular, a T-groove tg is provided on the upper side of the base frame 237 from one end to the other end in the longitudinal direction. This allows the fixing member 313 to be fixed at any position in the longitudinal direction on the upper side of the base frame 237. Therefore, the fixing positions of the floor frames 310A, 310B, and 310C relative to the upper side of the base frame 237 can be set arbitrarily. Here, when the floor frames 310A, 310B, and 310C are attached to the upper side of the base frame 237, the floor frames 310A, 310B, and 310C are disposed so as to extend upward from the upper side of the base frame 237. At this time, the upper surfaces (or lower surfaces) of the floor frames 310A, 310B, and 310C face the game area GE side. Similarly, a T-groove tg is provided on the inner surface of the base frame 237 from one end to the other end in the longitudinal direction. This allows the fixing member 313 to be fixed 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 set arbitrarily. Here, when the floor frames 310A, 310B, and 310C are attached to the inner surface of the base frame 237, the floor frames 310A, 310B, and 310C are arranged so as to extend from the inner surface of the base frame 237 toward the game area GE. At this time, the upper surface (or lower surface) of the floor frames 310A, 310B, and 310C faces upward.

[0047] As a result, for example, one of the floor frames 310A, 310B, 310C can be attached to the upper surface or inner surface of one of the base frames 237. At this time, the fixing position of the one of the floor frames 310A, 310B, 310C can be adjusted along the longitudinal direction of the base frame 237. In addition, two floor frames 310A, 310B, and 310C can be attached to the upper surface or inner surface of one base frame 237. Furthermore, one of the floor frames 310A, 310B, 310C can be attached so as to bridge between the two base frames 237. In this case, one of the two fixing members 313 provided on the fixing frame is fixed to the T-groove tg of one of the base frames 237, and the other fixing member 313 is fixed to the T-groove tg of the other base frame 237. This allows one of the floor frames 310A, 310B, 310C to be attached so as to bridge between the base frames 237 of two sets of individual lifting frames among the three sets of individual lifting frames 231-233 arranged on the left frame unit 221. Also, one of the floor frames 310A, 310B, 310C can be attached so as to bridge between the base frames 237 of two sets of individual lifting frames among the three sets of individual lifting frames 234-236 arranged on the right frame unit 222. In particular, one floor frame 310A, 310B, 310C is attached so as to span between the base frames 237 of two sets of individual lifting frames among the three sets of individual lifting frames 231-233 arranged on the left frame unit 221, and then the relative positional relationship (height relationship) of the base frames 237 of the two sets of individual lifting frames is changed (adjusted), thereby making it possible to arbitrarily change (adjust) the angle of the one floor frame 310A, 310B, 310C. At this time, in this embodiment, the angle of the one floor frame 310A, 310B, 310C can be arbitrarily changed by changing the relative positional relationship of the base frames 237 of the two sets of individual lifting frames while keeping each T-slot nut portion 313c in a state (fixed state) perpendicular to the T-slot tg. Similarly, among the three sets of individual lifting frames 234-236 arranged on the right frame unit 222, one floor frame 310A, 310B, 310C is attached so as to span between the base frames 237 of two sets of individual lifting frames, and then the relative positional relationship (height relationship) of the base frames 237 of the two sets of individual lifting frames is changed (adjusted), thereby making it possible to arbitrarily change (adjust) the angle of the one floor frame 310A, 310B, 310C. At this time, in this embodiment, the T-slot nut parts 313c are kept in a state (fixed state) perpendicular to the T-slot tg, and the relative positional relationship of the base frames 237 of the two sets of individual lifting frames is changed, thereby making it possible to arbitrarily change the angle of the one floor frame 310A, 310B, 310C.

[0048] In addition, each floor frame 310A, 310B, 310C can be attached to other floor frames 310A, 310B, 310C via fixing members 313. This makes it possible to connect multiple floor frames 310A, 310B, 310C. In this case, multiple floor frames 310A, 310B, 310C of any size can be connected. That is, when attaching the first floor frames 310A, 310B, 310C to the second floor frames 310A, 310B, 310C, first, the outer surface of any one of the four frames 311a, 311b (hereinafter referred to as the "first fixed frame") that constitute the first floor frames 310A, 310B, 310C is positioned facing the upper surface or outer surface (hereinafter referred to as the "fixed surface") of any one of the four frames 311a, 311b (hereinafter referred to as the "second fixed frame") that constitute the second floor frames 310A, 310B, 310C. Next, the T-slot nut portion 313c of each fixing member 313 provided on the first fixing frame is inserted into the T-slot 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-slot nut portion 313c with the longitudinal direction of the T-slot TG, it becomes possible to insert the T-slot nut portion 313c into the T-slot TG. Next, the operating portion 313b of each fixing member 313 is rotated to rotate the T-slot nut portion 313c by 90° in a predetermined direction. Then, in the T-slot TG, the T-slot nut portion 313c is displaced from a state parallel to the T-slot TG (released state) to a state perpendicular to the T-slot TG (fixed state). As a result, the T-slot nut portion 313c of each fixing member 313 is fixed in the T-slot TG. This causes the first fixing frame to be 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 with each other. In particular, when the T-groove nut portion 313c is displaced to a state (fixed state) perpendicular to the T-groove TG, the position of the T-groove nut portion 313c is fixed within the T-groove TG. This makes it 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 fixed 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-slot nut portion 313c is displaced to a state parallel to the T-slot TG (released state), the first fixing frame can be slid relative to the second fixing frame with the T-slot nut portion 313c remaining inserted in the T-slot 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-slot nut portion 313c from within the T-slot TG. In addition, by setting one of the pair of T-slot nut portions 313c in a state perpendicular to the T-slot TG (fixed state) and the other T-slot nut portion 313c in a state parallel to the T-slot TG (released state), it becomes possible to rotate the first fixed frame relative to the second fixed frame around one of the T-slot nut portions 313c (fixed member 313) as an axis. In this manner, the first floor frames 310A, 310B, 310C are attached to the fixing surfaces of the second floor frames 310A, 310B, 310C.

[0049] In particular, a T-groove TG is provided on the upper side of each frame 311a, 311b from one end to the other end 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 side of each frame 311a, 311b (second fixing frame). Therefore, it is possible to arbitrarily set the fixing position of the first floor frame 310A, 310B, 310C to the upper side of the second fixing frame. Here, when the first floor frame 310A, 310B, 310C is attached to the upper side of the second fixing frame, the first floor frame 310A, 310B, 310C is disposed so as to extend upward from the upper side of the second fixing frame. At this time, the upper surfaces of the first floor frames 310A, 310B, 310C and the upper surfaces of the second floor frames 310A, 310B, 310C are arranged so as to intersect. Similarly, a T-groove TG is provided on the outer surface of each of the frames 311a, 311b from one end to the other end in the longitudinal direction. This allows the fixing member 313 (fixing member 313 of the first fixing frame) to be fixed at any position in the longitudinal direction on the outer surface of each of the frames 311a, 311b (second fixing frame). Therefore, the fixing position of the first floor frame 310A, 310B, 310C relative to the outer surface of the second fixing frame can be set arbitrarily. Here, when the first floor frame 310A, 310B, 310C is attached to the outer surface of the second fixing frame, the first floor frame 310A, 310B, 310C is disposed so as to extend outward from the outer surface of the second fixing frame. At this time, the upper surfaces of the first floor frames 310A, 310B, 310C and the upper surfaces of the second floor frames 310A, 310B, 310C are arranged on the same plane.

[0050] As a result, for example, one floor frame 310A, 310B, 310C (first fixed frame) can be attached to the upper surface or outer surface of one frame 311a, 311b (second fixed frame). At this time, the fixing position of one floor frame 310A, 310B, 310C (first fixed frame) can be adjusted along the longitudinal direction of one frame 311a, 311b (second fixed frame). Two floor frames 310A, 310B, 310C (first fixed frames) can be attached to the upper surface 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 a T-slot TG (the same T-slot TG) provided on the second fixed frame. For example, as shown in FIG. 10, two small-sized floor frames 310A can be attached to the outer surface of a horizontal frame 311b of one medium-sized floor frame 310B. Also, one floor frame 310A, 310B, 310C (first fixed frame) can be attached so as to bridge between the upper or outer sides of two frames 311a, 311b (second fixed frames). 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. It is also possible to attach a type of frame member (hereinafter referred to as "old type frame member") that is fixed by screws as described in Patent Document 1 to the floor frames 310A, 310B, 310C. For this purpose, a T-slot nut (T-slot nut) is inserted into a T-slot TG provided on the upper or outer side (fixing surface) of one of the four frames 311a, 311b that constitute the floor frames 310A, 310B, 310C. Then, a screw inserted into a screw hole provided on the side of 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 provided on the fixing surface. This makes it possible to connect the floor frames 310A, 310B, 310C and the old type frame members.

[0051] (Floor Panel 320) FIG. 11 is a perspective view showing floor panel 320. FIG. 11 shows the floor panel 320 attached to the upper surface of the medium-sized floor frame 310B. 11, the floor panel 320 is formed in a substantially square flat plate shape in a plan view. The length and width of the floor panel 320 are the same as the length and width of the medium-sized floor frame 310B. A plurality of mounting portions (fixing portions) 321 are formed on the upper surface of floor panel 320. Various floor parts can be attached to each mounting portion 321. The multiple mounting portions 321 are regularly arranged in a predetermined pattern on the upper surface of the floor panel 320. Specifically, the multiple mounting portions 321 are arranged in a matrix on the upper surface of the floor panel 320. In this embodiment, 6 rows x 6 columns = 36 mounting portions 321 are arranged on the upper surface of the floor panel 320. The six mounting portions 321 constituting each row are arranged at equal intervals. Moreover, the six mounting portions 321 constituting each column are arranged at equal intervals. Furthermore, the interval between two adjacent mounting portions 321 in each row (hereinafter referred to as "column interval") and the interval between two adjacent mounting portions 321 in each column (hereinafter referred to as "row interval") are the same. In particular, the row spacing and column spacing can be set according to the intended game characteristics. For example, to realize a game in which floor parts are attached to two adjacent attachment parts 321 in each row or column, and the claw members 411a described below pass between the floor parts attached to the two attachment parts 321 to approach the prize P, 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 members 411a. In this case, the narrower the row spacing and column spacing, the more difficult it is to access the prize P, and the higher the difficulty of the prize acquisition game. On the other hand, the wider the row spacing and column spacing, the easier it is to access the prize P, and the lower the difficulty of the prize acquisition game. Alternatively, in order to realize a game characteristic in which floor parts are attached to two adjacent mounting parts 321 in each row or column, and the claw members 411a described below are prevented from passing between the floor parts attached to the two mounting parts 321, and only a direct approach to the prize P is permitted, 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 members 411a. As a result, when floor parts are attached to two adjacent mounting parts 321 in each row or column, the claw members 411a are prevented (impossible) from passing between the floor parts attached to the two mounting parts 321, making it possible to increase the difficulty of the prize acquisition game. In this embodiment, a plurality of claw members 411a with different widths are prepared as the claw members 411a. The row spacing and column spacing are set to be narrower than the width of the widest claw member 411a among the plurality of claw members 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 each column, the widest claw member 411a is prevented (impossible) from passing between the floor parts attached to the two mounting parts 321, and the narrowest claw member 411a is permitted (possible) to pass between the floor parts attached to the two mounting parts 321. On the other hand, in each row or column, when floor parts are attached to two mounting parts 321 with one mounting part 321 left open, the widest claw member 411a is allowed (made possible) to pass between the floor parts attached to the two mounting parts 321. In this embodiment, multiple mounting portions 321 are arranged in a matrix on the upper surface of floor panel 320, and multiple mounting portions 321 constituting each row and each column are arranged at equal intervals. However, multiple mounting portions 321 may be arranged on the upper surface of floor panel 320 according to other rules. Also, multiple mounting portions 321 constituting each row and each column do not have to be arranged at equal intervals. For example, on the upper surface of floor panel 320, a plurality of attachment portions 321 may be arranged radially. Alternatively, the multiple mounting parts 321 may be arranged concentrically on the upper surface of the floor panel 320. In this case, the interval between the multiple mounting parts 321 constituting the outer circle is set to be different from the interval between the multiple mounting parts 321 constituting the inner circle. For example, the interval between the multiple mounting parts 321 constituting the outer circle is set wider than the interval between the multiple mounting parts 321 constituting the inner circle. In particular, the interval between the multiple mounting parts 321 constituting the circle is set wider as the circle approaches the outer circle. As a result, when a floor part is attached to each of the multiple mounting parts 321 constituting each circle and the claw member 411a is configured to be able to hold the prize P more firmly as it passes between the multiple floor parts constituting the inner circle, it becomes more difficult for the claw member 411a to pass between the multiple floor parts constituting the circle as the circle approaches the inner circle. Alternatively, the interval between the multiple mounting parts 321 constituting the outer circle is set narrower than the interval between the multiple mounting parts 321 constituting the inner circle. In particular, the closer to the outer circle, the narrower the intervals between the multiple mounting parts 321 that make up the circle are set. This makes it more difficult for the prize P to pass between the multiple floor parts that make up the circle, when floor parts are attached to each of the multiple mounting parts 321 that make up each circle and the claw members 411a are used to scoop out the prize P from the center of the floor panel 320, the closer to the outer circle, the more difficult it becomes for the prize P to pass between the multiple floor parts that make up the circle.

[0052] Each mounting portion 321 is configured by fitting a hexagonal nut into a recess (hole) provided on the upper surface of floor panel 320. Here, instead of the hexagonal nut, a cylindrical member formed of an elastic body such as resin or rubber may be used. In particular, the upper surface of each mounting portion 321 (hexagonal nut) is lower than the upper surface of floor panel 320. In other words, the upper surface of each mounting portion 321 is recessed (sunk, sunken, or recessed) with respect to the upper surface of floor panel 320. This makes it possible to prevent claw member 411a from getting caught on each mounting portion 321. The upper surface of each mounting portion 321 (hexagonal nut) may be configured to be flush with the upper surface of the floor panel 320. Even in such a configuration, it is possible to prevent the claw members 411a from getting caught on the mounting portions 321.

[0053] The floor panel 320 can be attached to the upper surface (lower surface) of the floor frames 310A, 310B, 310C. In this case, when attaching a floor panel 320 to the upper surface of the small floor frame 310A, it is possible to connect two small floor frames 310A and attach one floor panel 320 to the upper surface of the two small floor frames 310A that form a single series. On the other hand, one floor panel 320 can be attached to the upper surface of the medium-sized floor frame 310B. On the other hand, three floor panels 320 can be attached in a line to the upper surface of the large floor frame 310C. In particular, by connecting multiple floor frames 310A, 310B, 310C, it is possible to attach multiple floor panels 320 side by side on the upper surfaces of the multiple continuous floor frames 310A, 310B, 310C. In this case, the column spacing and row spacing are configured to be the same between two adjacent floor panels 320. In this embodiment, only the floor panel 320 corresponding to the medium floor frame 310B is prepared. However, the floor panel 320 corresponding to the small floor frame 310A, the floor panel 320 corresponding to the medium floor frame 310B, and the floor panel 320 corresponding to the large floor frame 310C may be prepared. That is, the length and width of the floor panel 320 corresponding to the small floor frame 310A are the same as the length and width of the small floor frame 310A. Also, the length and width of the floor panel 320 corresponding to the medium floor frame 310B are the same as the length and width of the medium floor frame 310B. Also, the length and width of the floor panel 320 corresponding to the large floor frame 310C are the same as the length and width of the large floor frame 310C. Then, it is possible to attach one floor panel 320 (the floor panel 320 corresponding to the small floor frame 310A) to the upper surface of the small floor frame 310A. Also, it is possible to attach one floor panel 320 (floor panel 320 corresponding to the medium-sized floor frame 310B) to the upper surface of the medium-sized floor frame 310B. Also, it is possible to attach one floor panel 320 (floor panel 320 corresponding to the large-sized floor frame 310C) to the upper surface of the large-sized floor frame 310C. In this case, two floor panels 320 (two floor panels 320 corresponding to the small floor frame 310A) may be attached to the upper surface of the medium-sized floor frame 310B. Also, six floor panels 320 (six floor panels 320 corresponding to the small floor frame 310A) may be attached to the upper surface of the large floor frame 310C.

[0054] The floor panel 320 is fixed to the upper surfaces of the floor frames 310A, 310B, and 310C by screws. That is, a plurality of screw holes s are provided on the upper surface of the floor panel 320. When attaching the floor panel 320 to the upper surface of the floor frames 310A, 310B, 310C, first, a T-groove nut (T-slot nut) is inserted into the T-groove TG provided on the upper side of the frames 311a, 311b of the floor frames 310A, 310B, 310C. Next, the floor panel 320 is placed on the upper surface of the floor frames 310A, 310B, 310C. Then, the screws inserted into each screw hole s are fitted into the screw holes provided in the T-groove nut. This fixes the floor panel 320 to the upper surface of the floor frames 310A, 310B, 310C. At this time, the upper surface (top surface / top part) of the screw is lower than the upper surface of the floor panel 320. That is, the upper surface of the screw is concave (dropped / buried / depressed) with respect to the upper surface of the floor panel 320. This makes it possible to prevent the claw members 411a from getting caught on the screws.

[0055] (Various floor parts) FIG. 12 is a perspective view showing various floor parts. Here, FIG. 12 shows various floor parts attached to attachment portions 321 of a floor panel 320. In this embodiment, a columnar part 330, a hemispherical part 331, a conical part 332, a sphere part 333, and the like are prepared as various floor parts. As shown in FIG. 12, the column part 330 is formed in a cylindrical shape. The column part 330 is formed 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 part 321 (recess) provided on the upper surface of the floor panel 320. In particular, the claw member 411a is configured not to enter between the bottom surface of the column part 330 and the upper surface of the mounting part 321. As a result, when the column part 330 is attached to the mounting part 321, the bottom surface of the column part 330 covers the mounting part 321, making it possible to prevent the claw member 411a from getting caught on the mounting part 321. A screw portion is provided on the bottom surface of the column part 330. A screw hole is provided on the top surface of the column part 330. The column part 330 can be attached to the top surface of the floor panel 320 by fitting the screw portion into the attachment portion 321. 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-slot nut. In this case, the T-slot nut is inserted into the T-slot 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 screw hole provided in the T-slot nut. In this embodiment, a plurality of types of column parts 330 with different lengths are prepared. In particular, by fitting the screw part of one column part 330 into the screw hole of another column part 330, it is possible to connect one column part 330 to another column part 330 in a series. For example, a column part 330 having a length of 25.0 [mm] and a column part 330 having a length of 62.5 [mm] are prepared. As a result, by connecting one or more column parts 330, it is possible to configure floor parts of various lengths, such as 25.0 [mm] (1 [piece] of 25.0 [mm] column part 330), 50.0 [mm] (2 [pieces] of 25.0 [mm] column part 330), 62.5 [mm] (1 [piece] of 62.5 [mm] column part 330), 75.0 [mm] (3 [pieces] of 25.0 [mm] column part 330), 87.5 [mm] (1 [piece] of 25.0 [mm] column part 330 + 1 [piece] of 62.5 [mm] column part 330), and 100.0 [mm] (4 [pieces] of 25.0 [mm] column parts 330).

[0056] The hemispherical part 331 is formed in a hemispherical shape and 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 are formed from materials with different friction coefficients. This makes it possible to make the friction coefficient 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, making it possible to change the difficulty of winning the prize P. In addition, the outer surface (front surface and outer circumferential surface) of the hemispherical part 331 may be formed by combining a plurality of materials with different friction coefficients. For example, a predetermined portion of the outer surface of the hemispherical part 331 may be formed from a first material, and the other portion may be formed from a second material having a higher friction coefficient than the first material. This makes it possible to vary the friction coefficient depending on the portion on the outer surface of the hemispherical part 331. 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 placed, and it becomes possible to change the difficulty of winning the prize P. The diameter of the bottom surface of hemispherical part 331 is larger than the diameter of mounting portion 321 (recess) provided on the upper surface of floor panel 320. In particular, the claw members 411a are configured not to enter between the bottom surface of hemispherical part 331 and the upper surface of mounting portion 321. As a result, when hemispherical part 331 is attached to mounting portion 321, the bottom surface of hemispherical part 331 covers mounting portion 321, making it possible to prevent claw members 411a from getting caught on mounting portion 321. A screw portion is provided on the bottom surface of the hemispherical part 331. The hemispherical part 331 can be attached to the upper surface of the floor panel 320 by fitting the screw portion into the mounting portion 321. The hemispherical part 331 can also be attached to the top surface of the column part 330 by fitting the screw portion into a screw hole in the column part 330.

[0057] The cone part 332 is formed in a cone shape and is made of resin, rubber, metal, or the like. In particular, multiple cone parts 332 made of different materials may be prepared. In this case, the multiple cone parts 332 are formed from materials with different friction coefficients. This makes it possible to make the friction coefficient different for each cone part 332. As a result, the slipperiness of the prize P that comes into contact with the cone part 332 changes depending on the type of cone part 332 used, making it possible to change the difficulty of winning the prize P. In addition, the outer surface (front surface and outer circumferential surface) of the cone part 332 may be formed by combining a plurality of materials with different friction coefficients. For example, a predetermined portion of the outer surface of the cone part 332 may be formed of a first material, and the other portion may be formed of a second material having a higher friction coefficient than the first material. This makes it possible to vary the friction coefficient depending on the portion on the outer surface of the cone part 332. As a result, the slipperiness of the prize P in contact with the cone part 332 changes depending on the orientation in which the cone part 332 is installed, and the difficulty of winning the prize P can be changed. The diameter of the bottom surface of the cone 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 claw member 411a is configured not to enter between the bottom surface of the cone part 332 and the upper surface of the mounting portion 321. As a result, when the cone part 332 is attached to the mounting portion 321, the bottom surface of the cone part 332 covers the mounting portion 321, making it possible to prevent the claw member 411a from getting caught on the mounting portion 321. A threaded portion is provided on the bottom surface of the cone part 332. The cone part 332 can be attached to the upper surface of the floor panel 320 by fitting the threaded portion into the mounting portion 321. The cone part 332 can also be attached to the top surface of the column part 330 by fitting the threaded portion into a screw hole in the column part 330.

[0058] The spherical part 333 includes 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 formed from resin, rubber, metal, or the like. In particular, multiple spherical parts 333 having spherical portions 333a made of different materials may be prepared. In this case, the multiple spherical parts 333 have the spherical portions 333a formed of materials with different friction coefficients. This makes it possible to make the friction coefficient of the spherical portions 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 portions 333a changes depending on the type of spherical part 333 used, making it possible to change the difficulty of winning the prize P. In addition, the outer surface (front surface and outer circumferential surface) of the spherical portion 333a of each spherical part 333 may be formed by combining a plurality of materials having different friction coefficients. For example, a predetermined portion of the outer surface of the spherical portion 333a may be formed of a first material, and the other portion may be formed of a second material having a higher friction coefficient than the first material. This makes it possible to vary the friction coefficient depending on the portion on the outer surface of the spherical portion 333a. As a result, the slipperiness of the prize P, D-ring, etc. in contact with the spherical portion 333a changes depending on the orientation in which the spherical part 333 is installed, and it becomes possible to change the difficulty of winning the prize P. The cylindrical portion 333b is formed in a cylindrical shape. The cylindrical portion 333b is formed 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 claw member 411a is configured not to enter 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 bottom surface of the cylindrical portion 333b covers the mounting portion 321, making it possible to prevent the claw member 411a from getting caught on the mounting portion 321. A screw portion is provided on the bottom surface of the cylindrical portion 333b. The spherical part 333 can be attached to the upper surface of the floor panel 320 by fitting the screw portion into the mounting portion 321. The spherical part 333 can be attached to the top surface of the column part 330 by fitting the screw portion into a screw hole of the column part 330. The spherical part 333 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-slot nut. In this case, the T-slot nut is inserted into the T-slot TG provided on the upper or outer surface of the frames 311a and 311b, and the screw part of the spherical part 330 is fitted into the screw hole provided in the T-slot nut. In this embodiment, the spherical part 333 includes 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 configured without including the cylindrical portion 333b. In such a configuration, a screw portion is provided on the bottom surface of the spherical portion 333a.

[0059] (Flexible Rod 340) Fig. 13 is a perspective view showing flexible rod 340. Fig. 14 is a cross-sectional view perpendicular to the central axis of flexible rod 340. Fig. 15 is a cross-sectional view along the central axis of flexible rod 340. As shown in FIG. 13, flexible rod 340 includes a rod portion 341 and ball joint portions 342 attached to each end of rod portion 341 in the longitudinal direction (direction in which rod portion 341 extends). The rod portion 341 is composed of two cylindrical bodies 341a and 341b. That is, the rod portion 341 is composed by inserting (fitting) all or a part of the cylindrical body 341a into the inside of the 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. At this time, the cylindrical body 341a can be slid in a direction in which it is accommodated inside the cylindrical body 341b (hereinafter referred to as the "accommodating direction"), or in a direction in which it is ejected from inside the cylindrical body 341b (hereinafter referred to as the "ejecting direction"). When the cylindrical body 341a is slid in the storing direction, the rod portion 341 (flexible rod 340) contracts. On the other hand, when the cylindrical body 341a is slid in the discharging 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 storing direction or the discharging direction. As shown in FIG. 14, in this embodiment, the cross section perpendicular to the longitudinal direction of each of the cylindrical bodies 341a and 341b is teardrop-shaped. That is, on the outer circumferential surface of each of the cylindrical bodies 341a and 341b, an arc surface portion (curved surface portion), a flat surface portion, and a corner portion are formed along the circumferential direction. This makes it possible to change the frictional force acting on the prize P when the prize P is supported by the outer circumferential surface of the cylindrical bodies 341a and 341b, depending on whether the prize P is supported by the arc surface portion, the flat surface portion, or the corner portion. 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 arc surface portion, the flat surface portion, or the corner portion, and the difficulty of winning the prize P can be changed. Furthermore, when supporting the prize P with the outer peripheral surfaces of the cylindrical bodies 341a, 341b, it is possible to change the state in which the prize P is supported depending on the part that supports the prize P. In this case, the area of ​​contact with the prize P decreases in the order (larger → smaller) of the flat portion, the arc surface portion, and the corner portion. Therefore, it is possible to stably support the prize P in the order (stable → unstable) of the flat portion, the arc surface portion, and the corner portion. 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 arc surface portion, the flat portion, or the corner portion. The cross section of each of the cylindrical bodies 341a, 341b perpendicular to the longitudinal direction can be changed as appropriate to a circle, a polygon (triangle, square, pentagon, hexagon), or the like.

[0060] As shown in FIG. 15, each ball joint portion 342 includes 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 includes a cylindrical shaft portion 343a and a spherical portion 343b fixed to the tip end of the shaft portion 343a. The socket portion 344 includes a main body portion 344a and a lock 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 (contains) the spherical portion 343b therein. This makes it possible for each ball joint portion 342 to rotate (rotate circumferentially around the central axis of the ball stud portion 343 as the axis of rotation) and also to swing (change the direction and angle in which the central axis of the ball stud portion 343 extends) relative to the socket portion 344.

[0061] The locking mechanism 344b is capable of locking at least one of the rotation and swinging 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 to lock the swinging of the ball stud portion 343 relative to the socket portion 344. It is to be noted that the locking mechanism 344b may be configured to lock both the rotation and swinging of the ball stud portion 343 relative to the socket portion 344. That is, the lock mechanism 344b includes a cam lever 344c. The cam lever 344c can be operated (displaced) to a locked position or an unlocked position. Here, a slit (not shown) extending along the direction of the central axis is provided on the outer circumferential surface of the main body 344a. When the cam lever 344c is operated to the locked position, the spacing of the slits provided in the main body 344a narrows, and the inner circumference of the main body 344a contracts. This causes the inner circumference of the main body 344a to tighten the spherical portion 343b, locking the rotation of the ball stud portion 343 relative to the socket portion 344. At this time, the swinging movement of the ball stud portion 343 relative to the socket portion 344 is not locked. On the other hand, when the cam lever 344c is operated to the release position, the interval between the slits provided in the main body portion 344a becomes wider, and the inner circumference of the main body portion 344a expands. This releases the clamping of the spherical portion 343b by the inner circumference surface of the main body portion 344a, allowing the ball stud portion 343 to rotate and swing relative to the socket portion 344. The T-slot nut portion 345 is fixed to the bottom surface of the main body portion 344a. The T-slot nut portion 345 is formed in a rectangular plate shape in a plan view. In particular, the dimension (length) of the T-slot nut portion 345 in the longitudinal direction is larger than the width of each of the T-slots 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 of the T-slots TG, tg.

[0062] Each ball joint portion 342 is attached to the end of the rod portion 341 by fitting the shaft portion 343a into the inside of the cylindrical bodies 341a, 341b. At this time, the central axis of the shaft portion 343a and the central axis of the cylindrical bodies 341a, 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 is able to rotate and swing relative to the T-slot 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, the rod portion 341 can only swing relative to the T-slot nut portion 345 fixed to the ball joint portion 342, but cannot rotate. As a result, in the flexible rod 340, it is possible to change (adjust) the angle of the rod portion 341 relative to each socket portion 344. Also, in the flexible rod 340, it is possible to change (adjust) the distance between the pair of ball joint portions 342 (T-slot nut portions 345) by contracting or extending the rod portion 341.

[0063] The flexible rod 340 can be attached to the upper or inner surface of the base frame 237 . That is, when attaching the flexible rod 340 to the upper surface or inner surface (hereinafter referred to as the "fixed surface") of the base frame 237, first, the T-slot nut portion 345 provided at the end of the flexible rod 340 is inserted into the T-slot tg provided in the fixed surface of the base frame 237. At this time, by rotating the socket portion 344 to align the longitudinal direction of the T-slot nut portion 345 with the longitudinal direction of the T-slot tg, it becomes possible to insert the T-slot nut portion 345 into the T-slot tg. Next, the socket portion 344 is rotated to rotate the T-slot nut portion 345 by 90° in a predetermined direction. Then, in the T-slot tg, the T-slot nut portion 345 is displaced from a state in which it is parallel to the T-slot tg (released state) to a state in which it is perpendicular to the T-slot tg (fixed state). As a result, the T-slot nut portion 345 is fixed in the T-slot tg. This causes the end portion of the flexible rod 340 to be fixed to the base frame 237 with the bottom surface of the socket portion 344 (main body portion 344a) and the fixing surface in close contact with each other. In particular, when the T-slot nut portion 345 is displaced to a state (fixed state) perpendicular to the T-slot tg, the position of the T-slot nut portion 345 is fixed within the T-slot tg. This makes it 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 fixed 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. In this manner, the end of the flexible rod 340 is attached to the fixing surface of the base frame 237 . In particular, a T-slot tg is provided on the upper surface of the base frame 237 from one end to the other end in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 to any position in the longitudinal direction on the upper surface of the base frame 237. Therefore, it is possible to arbitrarily set the fixing position of the flexible rod 340 with respect to the upper surface of the base frame 237. Similarly, a T-slot tg is provided on the inner surface of the base frame 237, extending from one end to the other end in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 to any position in the longitudinal direction on the inner surface of the base frame 237. Therefore, it is possible to arbitrarily set the fixing position of the flexible rod 340 with respect to the inner surface of the base frame 237. At this time, when the T-slot nut portion 345 is displaced to a state (released state) parallel to the T-slot tg, the socket portion 344 can be slid relative to the base frame 237 with the T-slot nut portion 345 remaining inserted in the T-slot tg. This makes it possible to change (adjust) the fixed position of the socket portion 344 relative to the base frame 237 without removing the T-slot nut portion 345 from within the T-slot tg.

[0064] Furthermore, the flexible rod 340 can be attached to the floor frames 310A, 310B, and 310C. That is, when the flexible rod 340 is attached to the floor frames 310A, 310B, and 310C, first, the T-slot nut portion 345 provided at the end of the flexible rod 340 is inserted into the T-slot TG provided on the upper or outer side (hereinafter, "fixed surface") of one of the four frames 311a, 311b (hereinafter, "fixed frame") constituting the floor frames 310A, 310B, and 310C. At this time, the socket portion 344 is rotated to align the longitudinal direction of the T-slot nut portion 345 with the longitudinal direction of the T-slot TG, thereby making it possible to insert the T-slot nut portion 345 into the T-slot TG. Next, the socket portion 344 is rotated to rotate the T-slot nut portion 345 by 90° in a predetermined direction. Then, in 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). As a result, the T-slot nut portion 345 is fixed in the T-slot TG. This causes the end portion of the flexible rod 340 to be fixed to the fixed frame with the bottom surface of the socket portion 344 (main body portion 344a) and the fixed surface in close contact with each other. In particular, when the T-slot nut part 345 is displaced to a state (fixed state) perpendicular to the T-slot TG, the position of the T-slot nut part 345 is fixed within the T-slot TG. This makes it impossible to change the fixed position of the socket part 344 in the T-slot TG. On the other hand, when the T-slot nut part 345 is displaced to a state parallel to the T-slot TG (released state), the fixed position of the T-slot nut part 345 in the T-slot TG is released. This makes it possible to change the fixed position of the socket part 344 in the T-slot TG. In this manner, the ends of the flexible rod 340 are attached to the fixing surfaces of the floor frames 310A, 310B, and 310C.

[0065] In particular, a T-groove TG is provided on the upper surface of each of the frames 311a, 311b from one end to the other end in the longitudinal direction. This makes it possible to fix the end of the flexible rod 340 to any position in the longitudinal direction on the upper surface of each of the frames 311a, 311b. Therefore, it is possible to arbitrarily set the fixing position of the flexible rod 340 to the upper surface of each of the frames 311a, 311b. Similarly, a T-slot TG is provided on the outer surface of each of the frames 311a, 311b from one end to the other end 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 of the frames 311a, 311b. Therefore, it is possible to arbitrarily set the fixing position of the flexible rod 340 with respect to the outer surface of each of the frames 311a, 311b. At this time, when the T-slot nut part 345 is displaced to a state parallel to the T-slot TG (released state), the socket part 344 can be slid relative to the frames 311a, 311b with the T-slot nut part 345 remaining inserted in the T-slot TG. This makes it possible to change (adjust) the fixed position of the socket part 344 relative to the frames 311a, 311b without removing the T-slot nut part 345 from within the T-slot TG.

[0066] As a result of the above, 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 231-233 arranged on the left frame unit 221 and the base frame 237 of any of the three sets of individual lifting frames 234-236 arranged on the right frame unit 222. In addition, 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 231-233 arranged on the left frame unit 221 and the floor frames 310A, 310B, 310C attached to the base frame 237 of any of the three sets of individual lifting frames 234-236 arranged on the right frame unit 222. In addition, a flexible rod 340 can be attached so as to span between the floor frames 310A, 310B, 310C attached to the base frame 237 of any of the three sets of individual lifting frames 231-233 arranged on the left frame unit 221, and the base frame 237 of any of the three sets of individual lifting frames 234-236 arranged on the right frame unit 222. Furthermore, a flexible rod 340 can be attached so as to span between floor frames 310A, 310B, 310C attached to the base frame 237 of any of the three sets of individual lifting frames 231-233 arranged on the left frame unit 221, and floor frames 310A, 310B, 310C attached to the base frame 237 of any of the three sets of individual lifting frames 234-236 arranged on the right frame unit 222. In particular, in the flexible rod 340, it is possible to change (adjust) the slipperiness of the prize P placed on the rod portion 341 by changing (adjusting) the orientation of the outer circumferential surface of the rod portion 341. In this case, it is possible to make the prize P placed on the rod portion 341 less slippery when the rod portion 341 is placed with the corners facing upward than when the rod portion 341 is placed with the arc surface portion facing upward. Moreover, in the flexible rod 340, the rod portion 341 is configured to be freely 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 lock position. As a result, when the individual lifting frames 234 to 236 on which the flexible rod 340 is stretched are lifted or lowered relative to the entire lifting frame 220 with the cam lever 344c of the flexible rod 340 being operated to the lock position, the angle of the rod portion 341 relative to the socket portion 344 changes accordingly, and as a result, the inclination angle of the flexible rod 340 in the up-down direction changes. Therefore, when the cam lever 344c of the flexible rod 340 is operated to the lock position, it is possible to lift or lower the individual lifting frames 234 to 236 on which the flexible rod 340 is stretched relative to the entire lifting frame 220. At this time, when the cam lever 344c of the flexible rod 340 is operated to the locked position, the frictional force in the rotational direction 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 if the individual lifting frames 234-236 across which the flexible rod 340 is spanned are raised and lowered relative to the overall lifting frame 220 with the cam lever 344c of the flexible rod 340 operated to the locked position, the rod portion 341 does not rotate relative to the socket portion 344 in response.

[0067] (Example of the prize placement mechanism 30) Next, a configuration example of the prize placement mechanism 30 will be described. As described above, in this embodiment, by combining the small floor frame 310A, the medium floor frame 310B, the large floor frame 310C, the floor panel 320, various floor parts, the flexible rod 340, etc., it is possible to configure prize placement mechanisms 30 of various shapes. An example of the prize placement mechanism 30 is shown below.

[0068] (Example 1) First, the prize placement mechanism 30 according to the first example will be described. FIG. 16 is a diagram showing a configuration example of the prize placement mechanism 30 according to the first example. FIG. 17 is an enlarged view of the first floor panel 320 constituting the prize placement mechanism 30 according to the first example. FIG. 18 is an enlarged view of the second floor panel 320 constituting the prize placement mechanism 30 according to the first example. FIG. 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. FIG. 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. FIG. 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. 16, the prize placement mechanism 30 according to the first example is configured with two prize placement surfaces A and B in the game area GE as 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 are at different heights. That is, the prize placement mechanism 30 according to the first example is configured to include 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 arranged 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 included in the individual lifting frame 231. As a result, the first medium-sized floor frame 310B is disposed so as to extend from the inner surface of the base frame 237 included in the individual lifting frame 231 toward the game area GE. At this time, the first medium-sized floor frame 310B is attached to the inner surface of the base frame 237 provided on the individual lifting frame 231 by fixing two fixing members 313 provided on one side thereof to a T-groove 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 cantilever state. The second medium-sized floor frame 310B is attached to the middle individual lifting frame 235 of the three sets of individual lifting frames 234-236 arranged on the right frame unit 222. Specifically, the second medium-sized floor frame 310B is attached to the inner surface of the base frame 237 included in the individual lifting frame 235. As a result, the second medium-sized floor frame 310B is disposed so as to extend from the inner surface of the base frame 237 included in the individual lifting frame 235 toward the game area GE. At this time, the second medium-sized floor frame 310B is attached to the inner surface of the base frame 237 provided on the individual lifting frame 235 by fixing two fixing members 313 provided on one side thereof to a T-groove tg provided on the inner surface of the base frame 237. As a result, the second medium-sized floor frame 310B is attached to the individual lifting frame 235 in a cantilevered state.

[0069] A first floor panel 320 is attached to the upper surface of the first medium-sized floor frame 310B. As a result, a substantially horizontal first prize placement surface A is formed by the upper surface of the first floor panel 320. In addition, a plurality of column parts 330 are attached in a predetermined pattern to the first prize placement surface A. In this case, the plurality of column parts 330 are of the same type (length). Each column part 330 is attached to a mounting portion 321 of the floor panel 320. This allows the prize P to be placed on the first prize placement surface A with a part of the prize P floating, as shown in FIG. 17. That is, the top surface of the first floor panel 320 and the tip of the column part 330 can be used to support the bottom surface of the prize P on the first prize placement surface A. This allows a part of the bottom surface of the prize P to be floating relative to the top surface of the first floor panel 320. Therefore, for example, when placing a box-shaped prize P on the first prize placement surface A, a space can be created between the top surface of the first floor panel 320 and the bottom surface of the prize P to insert the claw member 411a.

[0070] A second floor panel 320 is attached to the upper surface of the second medium-sized floor frame 310B. As a result, a substantially horizontal second prize placement surface B is formed by the upper surface of the second floor panel 320. In addition, a plurality of column parts 330 are attached to the second prize placement surface B in a predetermined pattern. In particular, a plurality of prize placement sections are configured on the second prize placement surface B. Each prize placement section is configured by three column parts 330. In this case, of the three column parts 330, two column parts 330 having a short dimension (hereinafter, referred to as "short column parts 330") are used as the column parts 330, and one column part 330 having a long dimension (hereinafter, referred to as "long column part 330") is used as the column parts 330. Each prize placement section is configured by arranging the long column part 330 at a position between the two short column parts 330 and at a position on the rear side of the two short column parts 330. Each column part 330 is attached to the attachment part 321 of the floor panel 320. This makes it possible to place the prize P upright on the second prize placing surface B, as shown in Fig. 18. That is, the prize P can be supported upright by each prize placing section on the second prize placing surface B. At this time, in each prize placing section, the front of the prize P is supported by two short column parts 330, and the back of the prize P is supported by one long column part 330. Therefore, for example, when placing a flat bag-shaped prize P on the second prize placing surface B, the prize P can be arranged three-dimensionally.

[0071] Here, 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, 235. This makes it possible to adjust the heights of the first prize placement surface A and the second prize placement surface B individually. That is, when adjusting the height of each prize placing surface A, B, it is possible to adjust the height of the first prize placing surface A by raising and lowering the individual lifting frame 231 relative to the overall lifting frame 220. Also, it is possible to adjust the height of the second prize placing surface B by raising and lowering the individual lifting frame 235 relative to the overall lifting frame 220. This makes it possible to adjust the relative positional relationship (height relationship) between the first prize placing surface A and the second prize placing surface B. Thereafter, by raising and lowering the entire lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize holding portion 410 and each prize placing surface A, 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. That is, while the individual lifting / lowering locking mechanisms 239 are used to lock the lifting / lowering of the individual lifting / lowering frames 231 to 236 relative to the overall lifting / lowering frame 220 , the overall lifting / lowering frame 220 can be lifted / lowered relative to the base frame 210 .

[0072] The prize placement mechanism 30 according to the first example is configured as described above. The prize placement mechanism 30 according to the first example configures a prize placement area AE and an opening area OE in the game area GE. That is, the prize placement area AE is configured on each prize placement surface A, B in the game area GE, and the opening area OE is configured around each prize placement surface A, B. In particular, it is possible to configure a plurality of prize placement areas AE that are spaced apart from one another and have different heights in the game area GE. In the prize placement mechanism 30 of the first example, the prize holding portion 410 causes the prize P placed on each prize placement surface A, B to drop from the prize placement surface A, B, making it possible to obtain the prize P.

[0073] Here, various floor parts can be attached to the upper surface of each floor panel 320 (each prize placement surface A, B) according to the type of prize P. For example, as shown in FIG. 19, when a sewn-in gift is used as the prize P, a columnar floor part formed by connecting a plurality of columnar parts 330 in a series is attached to the upper surface of the floor panel 320. Then, the sewn-in gift is placed on the upper surface of the floor panel 320 so as to hold the columnar floor part. This allows the sewn-in gift to be placed in a standing or sitting position on the upper surface of the floor panel 320. In particular, it is possible to prevent the prize P from rolling down to the left or right due to interference from the prize gripping part 410. In addition, by lifting the prize P higher than the tip of the columnar floor part, it is possible to provide a game property in which the prize P can be acquired by releasing the prize P from holding the columnar floor part. 20, when a cylindrical object 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 for the pair of floor parts to prevent the prize P from rolling, and makes it possible to place the cylindrical prize P in a tilted state on the upper surface of the floor panel 320. At this time, it is possible to change (adjust) the difficulty of winning the prize P by changing (adjusting) the height of the pair of floor parts. 21, when a spherical object is used as the prize P, a plurality of floor parts are attached in a predetermined pattern to the upper surface of the floor panel 320 to form a path for guiding 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, thereby causing the prize P to fall into the opening area OE. In particular, as shown in FIG. 21, by attaching a wall member to the outer surface of the medium-sized floor frame 310B, it is possible to improve the gameplay of guiding the prize P along the path.

[0074] (Example 2) Next, a prize placement mechanism 30 according to a second example will be described. FIG. 22 is a diagram showing a configuration example of the prize placement mechanism 30 according to the second example. As shown in Fig. 22, the prize placing mechanism 30 of the second example is configured in a game area GE with a pair of prize placing surfaces A and B, and allows a prize P to be placed across the pair of prize placing surfaces A and B. The pair of prize placing surfaces A and B are spaced apart from each other via an opening area OE. Furthermore, each of the prize placing surfaces A and B is inclined toward the opening area OE. That is, the prize placement mechanism 30 according to the second example is configured to include 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 of the three sets of individual lifting frames 231-233 arranged in the left frame unit 221. Specifically, the first small floor frame 310A is attached to the upper side of the base frame 237 provided on the individual lifting frame 233. As a result, the first small floor frame 310A is arranged so as to extend upward from the upper side of the base frame 237 provided on 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 of the first small floor frame 310A to a T-groove tg provided on the upper side of the base frame 237 provided on the individual lifting frame 233. The second small floor frame 310A is attached to the rear individual lifting frame 236 of the three sets of individual lifting frames 234-236 arranged in the right frame unit 222. Specifically, the second small floor frame 310A is attached to the upper side of the base frame 237 provided on the individual lifting frame 236. As a result, the second small floor frame 310A is arranged so as to extend upward from the upper side of the base frame 237 provided on the individual lifting frame 236. In this case, the second small floor frame 310A is attached to the upper surface of the base frame 237 by fixing two fixing members 313 provided on one side of the second small floor frame 310A to a T-groove tg provided on the upper surface of the base frame 237 provided on the individual lifting frame 236.

[0075] The large floor frame 310C is bridged between the first small floor frame 310A (individual lifting frame 233) and the second small floor frame 310A (individual lifting frame 236). Specifically, one of the pair of vertical frames 311a constituting the large floor frame 310C is attached to the upper surface of the horizontal frame 311b constituting the first small floor frame 310A and to the inner surface of the base frame 237 constituting the individual lifting frame 233. At this time, one of the two fixing members 313 provided on the vertical frame 311a is fixed to a T-slot TG provided on the upper surface of the horizontal frame 311b, and the other fixing member 313 is fixed to a T-slot tg provided on the inner surface of the base frame 237. Furthermore, of the pair of vertical frames 311a constituting the large floor frame 310C, the other vertical frame 311a is attached to the upper surface of the horizontal frame 311b constituting the second small floor frame 310A and to the inner surface of the base frame 237 constituting the individual lifting frame 236. At this time, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-slot TG provided on the upper surface of the horizontal frame 311b, and the other fixing member 313 is fixed to a T-slot tg provided on the inner surface of the base frame 237. As a result, the large floor frame 310C is disposed with its upper surface inclined toward the front side. A flat floor panel fp is attached to the upper surface of the large floor frame 310C. Here, the upper surface of the flat floor panel fp is flat. That is, 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 constitutes the second prize placement surface B. At this time, the second prize placement surface B is inclined toward the front side.

[0076] Moreover, the prize placement mechanism 30 according to the second example is configured to include three medium-sized floor frames 310B. The three medium-sized floor frames 310B are connected in a row so that their upper surfaces are arranged on the same plane. The three medium-sized floor frames 310B connected in a row are spanned between the left frame unit 221 and the right frame unit 222. In the following description, of the three medium-sized floor frames 310B connected in a row, the medium-sized floor frame 310B arranged on the left side is referred to as the "left medium-sized floor frame 310B" and the medium-sized floor frame 310B arranged on the right side is referred to as the "right medium-sized floor frame 310B." Specifically, the vertical frame 311a constituting the left 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 231-233 arranged in the left frame unit 221. At this time, one of the two fixing members 313 provided on the vertical frame 311a is fixed to a T-slot 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-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 232. Further, the vertical frame 311a constituting the right-side medium-sized floor frame 310B is attached to the inner surface of the base frame 237 constituting the front individual lifting frame 234 and the inner surface of the base frame 237 constituting the middle individual lifting frame 235 among the three sets of individual lifting frames 234-236 arranged in the right-side frame unit 222. At this time, one of the two fixing members 313 provided on the vertical frame 311a is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 234, and the other fixing member 313 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 235. Furthermore, the base frames 237 of the individual lifting frames 232 and 235 are disposed at a lower position than the base frames 237 of the individual lifting frames 231 and 234. As a result, the three medium-sized floor frames 310B connected in a row are arranged with their upper surfaces inclined toward the rear. A flat floor panel fp is attached to the upper surface of the three medium-sized floor frames 310B connected in a row. As a result, the upper surface of the flat floor panel fp forms a first prize placement surface A. At this time, the first prize placement surface A is inclined toward the back side.

[0077] Here, in the prize arrangement mechanism 30 according to the second example, a large floor frame 310C and three medium floor frames 310B connected in a row are attached to different individual lifting frames 231 to 236. This makes it possible to adjust the heights of the first prize placement surface A and the second prize placement surface B individually. That is, when adjusting the height of each prize placing surface A, B, it is possible to adjust the height of the second prize placing surface B by raising or lowering the individual lifting frames 233, 236 relative to the overall lifting frame 220. Also, it is possible to change (adjust) the inclination angle of the second prize placing surface B 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. Moreover, it is possible to adjust the height of the first prize placing surface A by raising or lowering the individual lifting frames 231, 232, 234, 235 relative to the overall lifting frame 220. Moreover, it is possible to change (adjust) the inclination angle of the first prize placing surface A by changing (adjusting) the positional relationship (height relationship) between the base frame 237 of the individual lifting frames 231, 234 and the base frame 237 of the individual lifting frames 232, 235. This makes it possible to adjust the relative positional relationship (height relationship) between the first prize placing surface A and the second prize placing surface B. Thereafter, by raising and lowering the entire lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize holding portion 410 and each prize placing surface 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. That is, while the individual lifting / lowering locking mechanisms 239 are used to lock the lifting / lowering of the individual lifting / lowering frames 231 to 236 relative to the overall lifting / lowering frame 220 , the overall lifting / lowering frame 220 can be lifted / lowered relative to the base frame 210 .

[0078] The prize placement mechanism 30 according to the second example is constructed as described above. The prize placement mechanism 30 according to the second example configures a prize placement area AE and an opening area OE in the game area GE. That is, the prize placement area AE is configured on a pair of prize placement surfaces A and B in the game area GE, and the opening area OE is configured 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 that it spans between a pair of prize placement surfaces A, B. In the prize placement mechanism 30 of the second example, the prize holding portion 410 drops the prize P supported by a pair of prize placement surfaces A, B into the opening area OE, making it possible to obtain the prize P.

[0079] (Example 3) Next, a prize placement mechanism 30 according to a third example will be described. FIG. 23 is a diagram showing a configuration example of the prize placement mechanism 30 according to the third example. As shown in Figure 23, the prize placement mechanism 30 of the third example is configured with two prize hanging parts C and D in the game area GE as areas where a prize P can be hung (hereinafter referred to as "prize hanging parts"). That is, the prize placement mechanism 30 according to the third example is configured to include a large floor frame 310C. The large floor frame 310C is disposed between the left frame unit 221 and the right frame unit 222. Specifically, one of the pair of vertical frames 311a constituting the large floor frame 310C is attached to the inner surface of the base frame 237 constituting the middle individual lifting frame 232 and the inner surface of the base frame 237 constituting the rear individual lifting frame 233 among the three sets of individual lifting frames 231-233 arranged in the left frame unit 221. At this time, one of the two fixing members 313 provided on the vertical frame 311a is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 232, and the other fixing member 313 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 233. Further, of the pair of vertical frames 311a constituting the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 constituting the middle individual lifting frame 235 and the inner surface of the base frame 237 constituting the rear individual lifting frame 236 among the three sets of individual lifting frames 234-236 arranged in the right frame unit 222. At this time, of the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 235, and the other fixing member 313 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 236. Furthermore, the base frames 237 of the individual lifting frames 233 and 236 are disposed at a lower position than the base frames 237 of the individual lifting frames 232 and 235. As a result, the large floor frame 310C is arranged with its upper surface inclined toward the rear side. In other words, of the pair of horizontal frames 311b constituting the large floor frame 310C, the horizontal frame 311b on the near side is arranged at a higher position than the horizontal frame 311b on the rear side.

[0080] Two spherical parts 333 are attached to the outer surface of the front horizontal frame 311b constituting the large floor frame 310C. Each spherical part 333 is fixed to a T-slot TG provided on the outer surface of the horizontal frame 311b via a T-slot nut. Here, the fixing position of each spherical part 333 can be appropriately changed (adjusted) along the T-slot TG. Here, in the prize placement mechanism 30 of the third example, it is possible to change (adjust) the positional relationship (height relationship) between the base frame 237 of the individual lifting frames 232, 235 and the base frame 237 of the individual lifting frames 233, 236, thereby changing (adjusting) the inclination angle of each spherical part 333. Thereafter, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize holding portion 410 and each of the spherical parts 333 can be adjusted all at once while maintaining the inclination angle of each of the spherical parts 333. That is, while the individual lifting / lowering locking mechanisms 239 are used to lock the lifting / lowering of the individual lifting / lowering frames 231 to 236 relative to the overall lifting / lowering frame 220 , the overall lifting / lowering frame 220 can be lifted / lowered relative to the base frame 210 .

[0081] The prize placement mechanism 30 according to the third example is constructed as described above. The prize placement mechanism 30 of the third example constitutes a prize placement area AE and an opening area OE in the game area GE. That is, prize hanging parts C, D are constituted in the spherical portion 333a of each spherical part 333. A prize P can be suspended from each prize hanging part C, D via a D ring dr. This constitutes a prize placement area AE below each prize hanging part C, D. Also, an opening area OE is constituted below the prize P suspended from each prize hanging part C, D. In particular, in the game area GE, it becomes possible to arrange the prize P in a suspended state above the opening area OE. In the prize placement mechanism 30 of the third example, the prize holding portion 410 can be used to detach the D ring dr hooked to each prize hanging portion C, D from the prize hanging portion C, D, making it possible to obtain the prize P connected to the D ring dr.

[0082] (Example 4) Next, a prize placement mechanism 30 according to a fourth example will be described. FIG. 24 is a diagram showing a configuration example of the prize placement mechanism 30 according to the fourth example. 24, the prize placement mechanism 30 of the fourth example is configured with two prize hanging parts C and D in the game area GE as parts capable of hanging a prize P (hereinafter referred to as "prize hanging parts"). Also, in the game area GE, one prize display part E is configured as a part capable of displaying a prize P (hereinafter referred to as "prize display part"). That is, the prize placement mechanism 30 according to the fourth example is configured to include a large floor frame 310C. The large floor frame 310C is bridged between the individual lifting frame 233 arranged in the left frame unit 221 and the individual lifting frame 236 arranged in the right frame unit 222. Specifically, of the pair of vertical frames 311a constituting the large floor frame 310C, one vertical frame 311a is attached to the inner surface of the base frame 237 constituting the individual lifting frame 233. At this time, two fixing members 313 provided on the vertical frame 311a are fixed to T-slots tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 233. Of the pair of vertical frames 311a constituting the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 constituting the individual lifting frame 236. At this time, 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 constituting the individual lifting frame 236. Furthermore, a flat floor panel fp is attached to the upper surface of the large floor frame 310C. This allows the upper surface of the flat floor panel fp to be positioned horizontally. As a result, the prize display section E is formed by the upper surface of the flat floor panel fp. It is then possible to place spare prizes P on the prize display section E. Note that the prizes P placed on the prize display section E cannot be acquired by the prize gripping section 410, based on a setting that limits the movement range of the prize gripping section 410.

Each expansion base frame 240 has the same configuration as the base frame 237. That is, each expansion base frame 240 is formed in a quadrangular prism shape. A T-slot tg is provided on each of the four side surfaces of each expansion base frame 240. Each T-slot tg extends linearly along the longitudinal direction of the expansion base frame 240. Each T-slot tg is provided from one end to the other end of the longitudinal direction of the expansion base frame 240. Each expansion base frame 240 can be bridged (connected) between the base frames 237 of a pair of opposing individual lifting frames among the six sets of individual lifting frames 231 to 236. As a result, each expansion base frame 240 is disposed so as to extend along the left-right direction. Specifically, each expansion base frame 240 can be bridged 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.

Each expansion base frame 240 can be attached to the base frame 237 via the connecting metal fitting. At this time, the connecting metal fitting is provided with a fixing member having the same configuration as the fixing member 313. Each expansion base frame 240 can be attached to the base frame 237 by fixing the fixing member to the T-slot tg of the base frame 237.

[0084] In the prize placement mechanism 30 according to the fourth example, the first extended base frame 240 is bridged 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 frame 231 and the individual lifting frame 234 are connected together via the first extended base frame 240. Further, the second expansion base frame 240 is bridged 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. As a result, the individual lifting frames 232 and 235 are connected together via the second expansion base frame 240.

[0085] The first small floor frame 310A is attached to the upper side of the first expansion base frame 240. As a result, the first small floor frame 310A is arranged to extend upward from the upper side of the first expansion base frame 240.

[0087] A spherical part 333 is attached to the outer surface of the horizontal frame 311b constituting 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. The first prize hanging part C is formed in the spherical part 333a of the spherical part 333. Here, the fixing position of the spherical part 333 can be appropriately changed (adjusted) along the T-groove TG. A spherical part 333 is attached to the outer surface of the horizontal frame 311b constituting 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. The second prize hanging part D is formed in the spherical part 333a of the spherical part 333.

[0088] Here, in the fourth example of the prize arrangement mechanism 30, 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, 235. This makes it possible to adjust the heights of the first prize hanging part C and the second prize hanging part D individually. That is, when adjusting the height of the first prize hanging part C, it is possible to adjust the height of the first prize hanging part C by raising or lowering the individual lifting frames 231, 234 relative to the overall lifting frame 220. Also, it is possible to change (adjust) the inclination angle of the spherical part 333 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-sized floor frame 310A. Moreover, when adjusting the height of the second prize hanging part D, it is possible to adjust the height of the second prize hanging part D by raising or lowering the individual lifting frames 232, 235 relative to the overall lifting frame 220. Also, it is possible to change (adjust) the inclination angle of the spherical part 333 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-sized floor frame 310A. This makes it possible to adjust the relative positional relationship (height relationship) between the first prize hanging portion C, the second prize hanging portion D, and the prize display portion E. Thereafter, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize holding 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. That is, while the individual lifting / lowering locking mechanisms 239 are used to lock the lifting / lowering of the individual lifting / lowering frames 231 to 236 relative to the overall lifting / lowering frame 220 , the overall lifting / lowering frame 220 can be lifted / lowered relative to the base frame 210 .

[0089] The prize placement mechanism 30 according to the fourth example is constructed as described above. The prize placement mechanism 30 of the fourth example constitutes a prize placement area AE and an opening area OE in the game area GE. That is, prize hanging parts C, D are constituted in the spherical portion 333a of each spherical part 333. A prize P can be suspended from each prize hanging part C, D via a D ring dr. This constitutes a prize placement area AE below each prize hanging part C, D. Also, an opening area OE is constituted below the prize P suspended from each prize hanging part C, D. In particular, in the game area GE, it becomes possible to arrange the prize P in a suspended state above the opening area OE. In the prize placement mechanism 30 of the fourth example, the prize holding portion 410 can detach the D ring dr hooked to each prize hanging portion C, D from the prize hanging portion C, D, making it possible to obtain the prize P connected to the D ring dr.

[0090] (Example 5) Next, a prize placement mechanism 30 according to a fifth example will be described. FIG. 25 is a diagram showing a configuration example of the prize placement mechanism 30 according to the fifth example. 25, the prize placement mechanism 30 according to the fifth example has a portion (hereinafter, referred to as a "prize support portion") capable of supporting a prize P in the game area GE. Also, a prize display portion E is formed in the game area GE. That is, the prize placement mechanism 30 according to the fifth example is configured to include a large floor frame 310C. The large floor frame 310C is bridged between the individual lifting frame 233 arranged in the left frame unit 221 and the individual lifting frame 236 arranged in the right frame unit 222. Specifically, of the pair of vertical frames 311a constituting the large floor frame 310C, one vertical frame 311a is attached to the inner surface of the base frame 237 constituting the individual lifting frame 233. At this time, two fixing members 313 provided on the vertical frame 311a are fixed to T-slots tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 233. Of the pair of vertical frames 311a constituting the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 constituting the individual lifting frame 236. At this time, 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 constituting the individual lifting frame 236. Furthermore, a flat floor panel is attached to the upper surface of the large floor frame 310C. This allows the upper surface of the flat floor panel to be positioned horizontally. As a result, the prize display section E is formed by the upper surface of the flat floor panel. It is then possible to place spare prizes P on the prize display section E. Note that the prizes P placed on the prize display section E cannot be acquired by the prize gripping section 410, based on a setting that limits the movement range of the prize gripping section 410.

[0091] The prize placement mechanism 30 according to the fifth example is configured to include a pair of flexible rods 340. The pair of flexible rods 340 are spanned between the individual lifting frame 232 arranged in the left frame unit 221 and the individual lifting frame 234 arranged in the right frame unit 222 . Specifically, a socket portion 344 provided at one end of each flexible rod 340 is attached to the inner surface of a base frame 237 constituting the individual lifting frame 232. At this time, a T-slot nut portion 345 fixed to the socket portion 344 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 232. Further, 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 constituting the individual lifting frame 234. At this time, the T-slot nut portion 345 fixed to the socket portion 344 is fixed to the T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 234. In particular, a pair of flexible rods 340 are spanned between the base frame 237 constituting the individual lifting frame 232 and the base frame 237 constituting the individual lifting frame 234 so as to be arranged approximately parallel to each other at a predetermined interval. Furthermore, the base frame 237 of the individual lifting frame 232 is disposed at a higher position than the base frame 237 of the individual lifting frame 234 . As a result, the pair of flexible rods 340 are arranged in a state inclined in the depth direction by having one end disposed at a position deeper than the other end. Also, the pair of flexible rods 340 are arranged in a state inclined in the up-down direction by having one end disposed at a position higher than the other end. At this time, the rod portion 341 of each flexible rod 340 is configured to be freely extendable and retractable. Also, the rod portion 341 can be rotated (rotated in the circumferential direction around the central axis of the rod portion 341 as the axis of rotation) and can be swung (changing the direction and angle in which the central axis of the rod portion 341 extends) with respect to each socket portion 344. This allows each flexible rod 340 to be disposed at any position and angle. Therefore, each flexible rod 340 can be disposed in a state inclined in the depth direction and up-down direction.

[0092] Here, in the prize placement mechanism 30 of the fifth example, the individual lifting frames 232, 234 are raised and lowered relative to the overall lifting frame 220, making it possible to change (adjust) the vertical inclination angle of each flexible rod 340. At this time, in each flexible rod 340, the rod portion 341 is configured to be freely extendable and retractable. Also, in each flexible rod 340, when the cam lever 344c is operated to the lock position, the rotation of the rod portion 341 relative to the socket portion 344 is locked, but the swing of the rod portion 341 relative to the socket portion 344 is not locked. As a result, for each flexible rod 340, in a state where the cam lever 344c is operated to the lock position (a state where the rotation of the rod portion 341 relative to the socket portion 344 is locked), by raising and lowering the individual lifting frames 232, 234 relative to the entire lifting frame 220, it is possible to change (adjust) the inclination angle in the up-down direction of each flexible rod 340. At this time, the rod portion 341 extends and retracts in accordance with (follows) the raising and lowering of the individual lifting frames 232, 234 relative to the entire lifting frame 220, and the angle of the rod portion 341 relative to each socket portion 344 changes. In addition, by changing (adjusting) the fixed position of the T-slot nut portion 345 of each flexible rod 340 in the T-slot tg of each base frame 237, it is possible to change (adjust) the inclination angle of each flexible rod 340 in the depth direction. Thereafter, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize holding portion 410 and each flexible rod 340 can be adjusted all at once while maintaining the inclination angle of each flexible rod 340. That is, while the individual lifting / lowering locking mechanisms 239 are used to lock the lifting / lowering of the individual lifting / lowering frames 231 to 236 relative to the overall lifting / lowering frame 220 , the overall lifting / lowering frame 220 can be lifted / lowered relative to the base frame 210 .

[0093] The prize placement mechanism 30 according to the fifth example is constructed as described above. The prize placement mechanism 30 according to the fifth example constitutes a prize placement area AE and an opening area OE in the game area GE. That is, a pair of flexible rods 340 constitute a prize support section. The pair of flexible rods 340 (prize support section) are capable of supporting a prize P. As a result, the prize placement area AE is constituted above the pair of flexible rods 340. Also, the opening area OE is constituted below the pair of flexible rods 340. In particular, when multiple prizes P are arranged on a pair of flexible rods 340, the positions of the multiple prizes P can be arranged at different positions in the depth direction and the up-down 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 portion 410 causes the prize P supported by the prize support portion to fall from the prize support portion, making it possible for the prize P to be acquired.

[0094] (Example 6) Next, a prize placement mechanism 30 according to a sixth example will be described. FIG. 26 is a diagram showing a configuration example of the prize placement mechanism 30 according to the sixth example. As shown in FIG. 26, the prize placement mechanism 30 according to the sixth example has a prize support portion configured in the game area GE. That is, the prize placement mechanism 30 according to the sixth example is configured to include 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 among 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 included in the individual lifting frame 232. As a result, the medium-sized floor frame 310B is disposed so as to extend from the inner surface of the individual lifting frame 232 toward the game area GE. At this time, the medium-sized floor frame 310B is attached to the inner surface of the base frame 237 by fixing two fixing members 313 provided on one side thereof to a T-groove 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 cantilever state. Furthermore, a floor panel 320 is attached to the upper surface of the medium-sized floor frame 310B.

[0095] The first flexible rod 340 is suspended between the vertical frame 311 a of the medium-sized floor frame 310 B and the individual lifting frame 234 arranged in the right 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. At this time, the T-slot nut portion 345 fixed to the socket portion 344 is fixed to the T-slot TG provided on the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. Further, a 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 constituting the individual lifting frame 234. At this time, a T-slot nut portion 345 fixed to the socket portion 344 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 234. The second flexible rod 340 is suspended between the vertical frame 311 a of the medium-sized floor frame 310 B and the individual lifting frame 235 arranged in the right 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. At this time, the T-slot nut portion 345 fixed to the socket portion 344 is fixed to the T-slot TG provided on the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. Further, a 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 constituting the individual lifting frame 235. At this time, a T-slot nut portion 345 fixed to the socket portion 344 is fixed to a T-slot tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 235.

[0096] In particular, the first flexible rod 340 and the second flexible rod 340 are bridged between the medium-sized floor frame 310B and the individual lifting frames 234, 235 so as to extend in different directions from each other. Here, the base frame 237 of the individual lifting frame 234 is disposed at a lower position than the base frame 237 of the individual lifting frame 232. On the other hand, the base frame 237 of the individual lifting frame 235 is disposed at a higher position than the base frame 237 of the individual lifting frame 232. As a result, the first flexible rod 340 is arranged in a state inclined in the depth direction by being arranged at a position closer to the front end than the other end. Also, the first flexible rod 340 is arranged in a state inclined in the up-down direction by being arranged at a position lower than the other end. Moreover, the second flexible rod 340 is arranged in a state inclined in the depth direction by being arranged at a position where one end is located further back than the other end. Moreover, the second flexible rod 340 is arranged in a state inclined in the up-down direction by being arranged at a position where one end is located higher than the other end. At this time, the rod portion 341 of each flexible rod 340 is configured to be freely extendable and retractable. Also, the rod portion 341 can be rotated (rotated in the circumferential direction around the central axis of the rod portion 341 as the axis of rotation) and can be swung (changing the direction and angle in which the central axis of the rod portion 341 extends) with respect to each socket portion 344. This allows each flexible rod 340 to be disposed at any position and angle. Therefore, each flexible rod 340 can be disposed in a state inclined in the depth direction and up-down direction.

[0097] Here, in the prize placement mechanism 30 of the sixth example, it is possible to change (adjust) the vertical inclination angle of the first flexible rod 340 by raising and lowering the individual lifting frame 234 relative to the overall lifting frame 220. Moreover, by raising and lowering the individual lifting frame 235 relative to the entire lifting frame 220, the inclination angle of the second flexible rod 340 in the up-down direction can be changed (adjusted). At this time, in each flexible rod 340, the rod portion 341 is configured to be freely extendable and retractable. Also, in each flexible rod 340, when the cam lever 344c is operated to the lock position, the rotation of the rod portion 341 relative to the socket portion 344 is locked, but the swing of the rod portion 341 relative to the socket portion 344 is not locked. As a result, for each flexible rod 340, in a state where the cam lever 344c is operated to the lock position (a state where the rotation of the rod portion 341 relative to the socket portion 344 is locked), by raising and lowering the individual lifting frames 234, 235 relative to the entire lifting frame 220, it is possible to change (adjust) the inclination angle in the up-down direction of each flexible rod 340. At this time, the rod portion 341 extends and retracts in accordance with (follows) the raising and lowering of the individual lifting frames 234, 235 relative to the entire lifting frame 220, and the angle of the rod portion 341 relative to each socket portion 344 changes. In addition, by changing (adjusting) the fixed 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 of the first flexible rod 340 in the depth direction. Furthermore, by changing (adjusting) the fixed 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 of the second flexible rod 340 in the depth direction. Thereafter, by raising and lowering the overall lifting frame 220 relative to the base frame 210, the relative positional relationship (height relationship) between the prize holding portion 410 and each flexible rod 340 can be adjusted all at once while maintaining the inclination angle of each flexible rod 340. That is, while the individual lifting / lowering locking mechanisms 239 are used to lock the lifting / lowering of the individual lifting / lowering frames 231 to 236 relative to the overall lifting / lowering frame 220 , the overall lifting / lowering frame 220 can be lifted / lowered relative to the base frame 210 .

[0098] The prize placement mechanism 30 according to the sixth example is constructed as described above. The prize placement mechanism 30 of the sixth example constitutes a prize placement area AE and an opening area OE in the game area GE. That is, a pair of flexible rods 340 constitute a prize support section. The pair of flexible rods 340 (prize support section) can support a prize P. 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. This makes it possible to place the prize P in an upright state. As a result, a prize placement area AE is formed above the pair of flexible rods 340. In addition, below the pair of flexible rods 340, an opening area OE is formed. In the prize placement mechanism 30 of the sixth example, the prize gripping portion 410 causes the prize P supported by the prize support portion to fall from the prize support portion, making it possible for the prize P to be acquired.

[0099] (Crane Unit 40) Next, the configuration of the crane unit 40 will be described. The crane unit 40 is configured to include a prize gripping section 410, a moving device 420 that moves the prize gripping section 410 in the horizontal direction, and a lifting device 430 that raises and lowers the prize gripping section 410. The prize gripping unit 410 is attached to the bottom surface of the lifting device 430 via a stretchable support unit 413. The prize gripping unit 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 generally L-shaped rod shape. A claw member 411a is attached to the lower end of each arm 411. The opening and closing device 412 includes an opening and closing motor m1 and an opening and closing mechanism (not shown). In the opening and closing device 412, the pair of arms 411 can be opened and closed via the opening and closing mechanism by driving the opening and closing motor m1. The prize gripping section 410 can grip the prize P by opening and closing the pair of arms 411.

[0100] The moving device 420 includes 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 an upper horizontal member 214a of the base 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.

[0101] The lifting device 430 is attached to a 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 a Y-direction motor m3. The lifting device 430 is configured to include a reel (not shown) capable of letting out or winding the wire, and a lifting motor m4 that drives the reel. The tip of the wire is attached to the prize holding part 410. This makes it possible to drive the reel with the lifting motor m4 to let out the wire, thereby lowering the prize holding part 410. In addition, it is possible to raise the prize holding part 410 by driving the reel with the lifting motor m4 and winding the wire. As described above, in the crane unit 40, the prize gripping part 410 can be moved in the left-right direction, the depth direction, and the up-down direction by driving each of the motors m2, m3, and m3. In addition, the pair of arms 411 can be opened and closed by driving the opening / closing motor m1.

[0102] (Control board 50) Next, the configuration of the control board 50 will be described. FIG. 27 is a block diagram showing the configuration of the control board 50. As shown in FIG. 27, the control board 50 includes a control unit 51, a storage unit 52, and the like. The control unit 51 is configured by a microcomputer including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The control unit 51 executes processes required for the progress of the prize acquisition game based on various detection signals input from the control panel 13, programs and data stored in the memory unit 52, etc. The storage unit 52 is composed of a non-volatile memory, etc. The storage unit 52 stores programs and data required for the progress of the prize acquisition game. Here, the prize acquisition game device 1 is equipped with an X position detection means 53 which detects the position of the prize holding portion 410 in the X direction (left and right direction), a Y position detection means 54 which detects the position of the prize holding portion 410 in the Y direction (depth direction), and a Z position detection means 55 which detects the position of the prize holding portion 410 in the Z direction (up and down direction). The control unit 51 receives detection signals output in response to pressing of the operation buttons 16a and 16b, detection signals output by the position detection means 53, 54, and 55, and the like.

[0103] When the control unit 51 detects the insertion of a coin into the coin insertion slot 14, it starts a prize acquisition game. During the prize acquisition game, first, the input of a detection signal from the first operation button 16a is monitored. Then, in response to the input of the detection signal from the first operation button 16a, the X-direction motor m2 is driven to move the prize gripping part 410 in the left-right direction. Next, the input of the 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 to move the prize gripping part 410 along the depth direction. Then, when the movement of the prize gripping part 410 along the depth direction is completed, the lifting motor m4 is driven, and the prize gripping part 410 is lowered to a predetermined height, and then the opening / closing motor m1 is driven, and the pair of arms 411 is closed. After that, the prize gripping part 410 is raised to a predetermined height, and then the prize gripping part 410 is moved to a predetermined position (opening area OE). Then, at the predetermined position, the opening / closing motor m1 is driven, and the pair of arms 411 is opened. Thereafter, the prize gripping portion 410 is moved to the home position, and the current prize acquisition game is ended.

[0104] (Modification) Although the embodiment of the present invention has been described above, various modifications can be made to the above embodiment. For example, in the above embodiment, the entire lifting frame 220 may be configured to be movable relative to the base frame 210 in the depth direction. For example, the base frame 210 is provided with a mechanism for moving the entire lifting frame 220 along the depth direction, and a locking mechanism capable of locking the movement of the entire lifting frame 220 along the depth direction. Specifically, a member for integrating the pair of left whole lift guide rails 216a, 216b and a member for integrating the pair of right whole lift guide rails 217a, 217b are provided. In addition, a mechanism for allowing the integrated pair of left whole lift guide rails 216a, 216b to move along the depth direction relative to the middle cross member 212b and the lower cross member 212c, and a mechanism for allowing the integrated pair of right whole lift guide rails 217a, 217b to move along the depth direction relative to the middle cross member 213b and the lower cross member 213c are provided. Furthermore, as a lock mechanism, a mechanism similar to the whole lift lock mechanism 218 or a latch mechanism is provided. With this configuration, by releasing the locking mechanism, the six sets of individual lifting frames 231 to 236 that are attached to the overall lifting frame 220 so as to be able to rise and fall can be pulled out collectively toward the front side relative to the base frame 210. This enables the operator to configure the prize arrangement mechanism 30 with the six sets of individual lifting frames 231-236 pulled out towards the front, making it possible to easily configure the prize arrangement mechanism 30. After the construction of the prize arrangement mechanism 30 is completed, the six individual lifting frames 231 to 236 are pushed all together toward the back of the base frame 210 to be placed in their original positions, and are locked by the locking mechanism.

[0105] In the above embodiment, the left frame unit 221 has three sets of individual lifting frames 231 to 233 attached thereto. However, the left frame unit 221 may be configured to have one set of individual lifting frames attached thereto, or the left frame unit 221 may be configured to have four or more sets of individual lifting frames attached thereto. Similarly, in the above embodiment, the right frame unit 222 has three sets of individual lifting frames 234 to 236 attached thereto. However, the right frame unit 222 may have one set of individual lifting frames attached thereto, or the right frame unit 222 may have four or more sets of individual lifting frames attached thereto.

[0106] In the above embodiment, the base frame 237 is formed in a quadrangular prism shape. That is, a cross section perpendicular to the longitudinal direction of the base frame 237 is quadrangular. A T-groove tg is provided on each of the four side surfaces of the base frame 237. However, the base frame 237 may be formed into another polygonal prism shape such as a triangular prism, a pentagonal prism, a hexagonal prism, etc. In other words, the cross section perpendicular to the longitudinal direction of the base frame 237 may be another polygon shape such as a triangle, a pentagon, a hexagon, etc. Furthermore, a T-groove tg may be provided on each side surface of the base frame 237. With this 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.

[0107] In the above embodiment, the entire lifting frame 220 may be provided with a T-shaped groove. For example, a T-slot is provided on the inner side surface of the upper frame 224a, 224b. In this case, the T-slot is provided so as to extend along the upper frame 224a, 224b. The configuration of the T-slot is the same as the configuration of each T-slot tg, TG. That is, the shape of a cross section perpendicular to the longitudinal direction of each T-slot tg, TG is the same as the shape of a cross section perpendicular to the longitudinal direction of each T-slot tg, TG. In particular, the dimensions (opening width, bottom width, depth) of each T-slot are the same as the dimensions (opening width, bottom width, depth) of each T-slot tg, 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, the base frame 237 is provided with a pair of through holes penetrating in the up-down direction, and a pair of guide rods 238 provided on the individual lifting frames 231-236 are inserted into the pair of through holes.

[0108] In the above embodiment, the floor frames 310A, 310B, and 310C are configured as a substantially rectangular frame body in a plan view. However, the floor frames 310A, 310B, 310C may be configured as frames having other polygonal shapes, such as a substantially triangular, substantially pentagonal, or substantially hexagonal shape, in a plan view.

[0109] In the above embodiment, the floor frames 310A, 310B, and 310C are configured as a substantially rectangular frame body (frame portion) in a plan view. However, the floor frames 310A, 310B, 310C may be configured as a frame body (frame portion) having a substantially lattice shape (ladder shape) in a plan view. For example, the floor frames 310A, 310B, and 310C may be configured as a substantially lattice-shaped (ladder-shaped) frame body (frame portion) made up 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 frame 311a spanning each end of the pair of horizontal frames 311b in the longitudinal direction, the vertical frame 311a may be spanned approximately in 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 the floor panel 320, flexible rod 340, etc. can be attached.

[0110] In the above embodiment, each of the frames 311a, 311b is formed in a quadrangular prism shape. That is, a cross section perpendicular to the longitudinal direction of each of the frames 311a, 311b is quadrangular. A T-groove TG is provided on each of the four side surfaces of each of the frames 311a, 311b. However, each of the frames 311a, 311b may be formed into another polygonal prism shape such as a triangular prism, a pentagonal prism, a hexagonal prism, etc. In other words, the cross section of each of the frames 311a, 311b perpendicular to the longitudinal direction may be another polygon shape such as a triangle, a pentagon, a hexagon, etc. Furthermore, a T-groove TG may be provided on each side surface of each of the frames 311a, 311b. With this 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.

[0111] In the above embodiment, the floor panel 320 is configured to be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by screws. However, the floor panel 320 may be configured to be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by hook pieces (hook pieces or claw pieces). That is, a plurality of hooks are provided on the lower surface of the floor panel 320. Each hook is provided so as to extend downward from the lower surface of the floor panel 320. The lower end of each hook is bent outward. When attaching floor panel 320 to the upper surfaces of floor frames 310A, 310B, and 310C, the lower ends of the hooks are hooked into T-grooves TG provided on the inner surfaces of frames 311a and 311b of floor frames 310A, 310B, and 310C. This makes it possible to fix floor panel 320 to the upper surfaces of 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 including a shaft portion, a plug portion provided at the lower end of the shaft portion, and a head portion provided at the upper end of the shaft portion is used. The shaft portion of the fastener is inserted into a hole portion provided on the upper surface of the floor panel 320. At this time, the head portion is disposed on the upper surface side of the floor panel 320, and the plug portion is disposed on the lower surface side of the floor panel 320. Then, the plug portion is inserted into a socket portion provided in the frames 311a and 311b, whereby the plug portion is locked (fixed) in 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 in the socket portion. Alternatively, the floor panel 320 may be attached to the upper surface of the floor frames 310A, 310B, and 310C by a T-slot nut having a screw head. In this case, a fastener including a shaft portion, a T-slot nut provided at the lower end of the shaft portion, and a screw head provided at the upper end of the shaft portion is used. The shaft portion of the fastener is inserted into a hole provided on the upper surface of the floor panel 320. At this time, the screw head is placed on the upper surface side of the floor panel 320, and the T-slot nut is placed on the lower surface side of the floor panel 320. Then, after inserting the T-slot nut into the T-slot TG, the screw head is rotated by a screwdriver or the like to fix the T-slot nut in the T-slot TG. Alternatively, the floor panel 320 may be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by a screw portion (bolt foot) provided on the lower surface of the floor panel 320. In this case, a hole portion through which the screw portion provided on the lower surface of the floor panel 320 is inserted is provided in the frames 311a and 311b of the floor frames 310A, 310B, and 310C. Then, the lower end portion of the screw portion penetrating from the upper surface side to the lower surface side of the frames 311a and 311b through the hole portion is fixed with a wing nut or the like after sandwiching a fixing plate.

[0112] In the above embodiment, the floor panel 320 is configured to be attached to the upper surfaces of the floor frames 310A, 310B, and 310C. However, the floor panel 320 may be configured to be attachable to at least one of the upper and lower surfaces of the floor frames 310A, 310B, and 310C.

[0113] 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 members 411a. This prevents the claw members 411a from passing between the floor parts attached to the two mounting portions 321 that are adjacent to each other in each row or column. However, the row spacing and column spacing of the multiple mounting portions 321 on the upper surface of the floor panel 320 may be wider than the width of the claw members 411a. This allows the claw members 411a to pass between the floor parts attached to two adjacent mounting portions 321 in each row or column.

[0114] In the above embodiment, the floor frames 310A, 310B, 310C and the floor panel 320 (or the flat floor panel fp) are configured as separate members. However, the floor frames 310A, 310B, 310C and the floor panel 320 (or the flat floor panel fp) may be configured as an integral member.

[0115] In the above embodiment, floor panel 320 is formed in a substantially square flat plate shape in plan view. However, floor panel 320 may be configured in a three-dimensional shape. For example, floor panel 320 may be configured in a quadrangular pyramid shape, a quadrangular pyramid frustum shape, a triangular prism laid on its side, etc. In such a configuration, a plurality of mounting portions 321 are provided on the surface (slope or top surface) of floor panel 320.

[0116] In the above embodiment, the upper surface of the floor panel 320 is provided with a plurality of attachment portions 321. However, a configuration in which multiple T-slots are provided on the upper surface of the floor panel 320 may be used. For example, a configuration in which multiple T-slots extending parallel to each other are provided at a predetermined interval on the upper surface of the floor panel 320 may be used. Each T-slot extends linearly along one side of the floor panel 320. Each T-slot TG is provided from one end of one side of the floor panel 320 to the other end. The configuration of each T-slot is the same as the configuration of each T-slot tg, TG. That is, the shape of a cross section perpendicular to the longitudinal direction of each T-slot is the same as the shape of a cross section perpendicular to the longitudinal direction of each T-slot tg, TG. In particular, the dimensions (opening width, bottom width, depth) of each T-slot are the same as the dimensions (opening width, bottom width, depth) of each T-slot tg, TG.

[0117] In the above embodiment, in the flexible rod 340, the cross section perpendicular to the longitudinal direction of each of the cylindrical bodies 341a and 341b is teardrop-shaped. However, in flexible rod 340, the cross section perpendicular to the longitudinal direction of each of cylindrical bodies 341a, 341b can be changed as appropriate to a circle, a polygon (triangle, square, pentagon, hexagon), or the like.

[0118] In the above embodiment, the flexible rod 340 is provided with a T-slot nut portion 345 on the bottom surface of the socket portion 344 (main body portion 344a). However, the flexible rod 340 may be configured such that the T-slot nut portion 345 is not 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 attached to the panel member by inserting the socket portion 344 into the hole. This makes it possible, for example, to arrange the flexible rod 340 so as to span between a hole portion of a panel member attached to the base frame 237 of the individual lifting frame 231 and a hole portion of a panel member attached to the base frame 237 of the individual lifting frame 234.

[0119] In the above embodiment, each mounting portion 321 is configured by fitting a hexagonal nut into a recess (hole) provided on the upper surface of floor panel 320. Also, a threaded portion is provided on the bottom surface of each of the various floor parts (columnar part 330, semi-spherical part 331, conical part 332, spherical part 333, etc.). The various floor parts are attached to mounting portion 321 by fitting the threaded portion into mounting portion 321. However, various floor parts may be attached to the attachment portion 321 by a one-touch joint (coupler). Specifically, each mounting portion 321 is configured by fitting a socket portion into a recess (hole) provided on the upper surface of floor panel 320. Also, a plug portion that fits into the socket portion is provided on the bottom surface (lower end) of each floor part. Then, by inserting (fitting) the plug portion into the socket portion, the plug portion is locked (fixed) in the socket portion, and each floor part is attached to mounting portion 321. Also, by operating a release ring provided on the plug portion, the lock of the plug portion by the socket portion is released, making it possible to remove each floor part from mounting portion 321.

[0120] 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-grooves TG of the floor frames 310A, 310B, and 310C. However, the floor panel 320 may be configured to be attached to the base frame 237. Specifically, the floor panel 320 may be configured to be attached to a T-groove tg of the base frame 237.

[0121] (Function of Prize Acquisition Game Device 1) The flexible rod 340 constitutes the prize placement mechanism 30 for placing prizes P within the game area GE. The flexible rod 340 also includes a rod portion 341 and socket portions 344 (T-slot nut portions 345) provided at each end of the rod portion 341. In particular, the angle of the rod portion 341 relative to the socket portions 344 (T-slot nut portions 345) can be changed. This allows the angle of the rod portion 341 relative to the socket portion 344 (T-groove nut portion 345) to be changed (adjusted) to various angles in the flexible rod 340. Therefore, it becomes possible to arrange the rod portion 341 at various angles, and it becomes possible to diversify the configuration of the prize arrangement mechanism 30. Further, in the flexible rod 340, the socket portion 344 (T-slot nut portion 345) can be attached to a T-slot tg provided in the base frame 237 of the prize acquisition game device 1. This makes it possible to adjust the attachment position of the socket portion 344 (T-slot nut portion 345) along the T-slot tg. Moreover, in the flexible rod 340, the rod portion 341 is configured to be extendable and retractable. This makes it possible to change (adjust) the length of the rod portion 341, and further diversify the configuration of the prize placement mechanism 30.

[0122] In the flexible rod 340, the cross section of the rod portion 341 (cross section perpendicular to the longitudinal direction) is teardrop-shaped. This makes it possible to change the frictional force acting on the prize P when the prize P is supported by the outer circumferential surface of the rod portion 341 depending on whether the prize P is supported by the arcuate surface portion, the flat surface portion, or the corner portion (tip portion). 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 portion, the flat surface portion, or the corner portion, making it possible to change the difficulty of winning the prize P. Furthermore, when the prize P is supported by the outer peripheral surface of the rod portion 341, it is possible to change the state in which the prize P is supported depending on the part that supports the prize P. In this case, the area of ​​contact with the prize P increases in the order (large → small) of the flat portion, the arc surface portion, and the corner portion. Therefore, it is possible to stably support the prize P in the order (stable → unstable) of the flat portion, the arc surface portion, and the corner portion. 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 arc surface portion, the flat portion, or the corner portion. Moreover, the flexible rod 340 is provided with a locking mechanism 344b that locks the rotation of the rod portion 341 relative to the socket portion 344 (the T-slot nut portion 345). This makes it possible to prevent a situation in which the prize P can be easily acquired by the rotation of the rod portion 341. In addition, in the flexible rod 340, when the rotation of the rod portion 341 relative to the socket portion 344 (T-slot nut portion 345) is locked by the locking mechanism 344b, it is possible to change (swing) the angle of the rod portion 341 relative to the socket portion 344 (T-slot nut portion 345). This makes it possible to simplify the configuration of the prize placement mechanism 30. As a result, in the prize acquisition game device 1, the configuration of the prize placement mechanism 30 can be diversified. [Explanation of symbols]
