Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, an example in which the prize acquisition game device according to the present invention is applied to a prize acquisition game device 1 capable of executing a prize acquisition game will be described. In the "prize acquisition game", when a player (user) operates an operation unit 16, a prize gripping unit 410 is operated, and a prize P arranged in a prize arrangement area AE is dropped into an opening area OE, so that the prize P can be acquired. It is a game that can be obtained. The "prize P" may be an article given to the player by acquisition, an article that is not given to the player even if acquired, or an article that can be exchanged with other articles (articles given to the player) after acquisition. Either way is acceptable.

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

[0012] As shown in FIG. 1, the prize-winning game device 1 includes a housing 10, a base frame unit 20 disposed within the housing 10, a prize arrangement 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 FIG. 27) disposed within the housing 10.

[0013] (Housing 10) First, the configuration of the housing 10 will be described. The housing 10 is formed in a box shape. Inside the housing 10, a game area (play area) GE where a prize-winning game is developed is configured. 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 composed of a transparent plate material such as glass or an acrylic plate. As a result, the player can visually recognize the game area GE configured inside the housing 10 from the outside of the housing 10. The front of the upper housing 11 is composed of a sliding door and can be opened and closed. As a result, the operator (administrator) can perform operations such as arranging and moving prizes P and configuring and changing the configuration of the prize arrangement 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 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. The coin insertion slot 14 enables the player to insert coins. The player can obtain credit for playing the prize-winning game by inserting coins into the coin insertion slot 14. Note that a settlement device for electronic money using a storage medium such as a prepaid card or a credit card may be provided, and it may be configured to obtain credit by settling with electronic money. The credit display unit 15 displays the remaining number of credits acquired by the player. That is, each time the player acquires credits by inserting coins into the coin insertion slot 14, the remaining number of credits displayed on the credit display unit 15 increases. Also, each time the prize acquisition game is played, the remaining number of credits displayed on the credit display unit 15 decreases.

[0015] The operation unit 16 receives the operations of the player. The operation unit 16 includes a first operation button 16a and a second operation button 16b. Each operation button 16a, 16b can be pressed by the player. The first operation button 16a receives an operation to move the prize gripping unit 410 along the X direction (left - right direction) during the prize acquisition game. The second operation button 16b receives an operation to move the prize gripping unit 410 along the Y direction (depth direction) during the prize acquisition game. Note that the operation unit 16 may include a third operation button that receives an operation to move the prize gripping unit 410 along the Z direction (up - down direction) during the prize acquisition game. Or, as the operation unit 16, a joystick that receives an operation to move the prize gripping unit 410 along the horizontal direction (left - right direction and depth direction) and a down button that receives an operation to move the prize gripping unit 410 along the Z direction (up - down direction) may be provided during the prize acquisition game.

[0016] Also, a prize outlet 17 communicating with the opening area OE is provided on the front surface of the lower housing 12. Here, a prize slope (not shown) is arranged below the prize arrangement mechanism 30. And the prize P that has fallen into the opening area OE is guided to the prize outlet 17 by the prize slope. As a result, the player can acquire the prize P taken out from the prize outlet 17. Also, an opening / closing door 19 is provided on the front surface of the lower housing 12. And various control boards (such as the control board 50) are arranged inside the opening / closing door 19.

[0023] Also, between the two rear vertical members 211c and 211d, an upper horizontal member 214a and a lower horizontal member 214b are spanned. The upper horizontal member 214a is spanned across the upper ends of the two vertical members 211c and 211d. The lower horizontal member 214b is spanned across the lower ends of the two vertical members 211c and 211d. Furthermore, between the upper horizontal member 212a and the upper horizontal member 213a, an upper horizontal member 215 is spanned. The upper horizontal member 215 is spanned across the front - side ends of the upper horizontal member 212a and the upper horizontal member 213a.

[0024] Also, the base frame 210 is configured to include a pair of left - side overall lifting guide rails 216a and 216b, and a pair of right - side overall lifting guide rails 217a and 217b. Each of the left - side overall lifting guide rails 216a and 216b is composed of a flat - plate - shaped member having a predetermined length. Each of the left - side overall lifting guide rails 216a and 216b is provided with a guide groove (guide rail) 216c. The guide groove 216c extends linearly along the longitudinal direction (the direction in which the left - side overall lifting guide rails 216a and 216b extend). Each left-side overall lifting guide rail 216a, 216b is spanned between the intermediate horizontal member 212b and the lower horizontal member 212c. As a result, each left-side overall lifting guide rail 216a, 216b is arranged in a state where the guide groove 216c extends along the vertical direction. Also, the pair of left-side overall lifting guide rails 216a, 216b are arranged at a predetermined interval in a state where the guide grooves 216c face each other. Each right-side overall lifting guide rail 217a, 217b is composed of a flat plate-shaped member having a predetermined length.

Each right-side overall lifting guide rail 217a, 217b is spanned between the intermediate horizontal member 213b and the lower horizontal member 213c. As a result, each right-side overall lifting guide rail 217a, 217b is arranged in a state where the guide groove 217c extends along the vertical direction. Also, the pair of right-side overall lifting guide rails 217a, 217b are arranged at a predetermined interval in a state where the guide grooves 217c face each other.

[0025] (Overall lifting frame 220) FIG. 5 is an enlarged view showing the left frame unit 221. Here, FIG. 5 shows a state in which, in the base frame unit 20, the front-side left-side overall lifting guide rail 216a and the first individual lifting guide rail 227a are omitted from display. The overall lifting frame 220 includes 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 bilaterally symmetric 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 is configured to include an upper side frame 224a and a lower side frame 225a that are arranged in parallel. Further, the left frame unit 221 is configured to include a pair of overall lifting sliders 226a, 226b, a first individual lifting guide rail 227a, a second individual lifting guide rail 228a, and a third individual lifting guide rail 229a that are spanned between the upper side frame 224a and the lower side frame 225a. The right frame unit 222 is configured to include an upper side frame 224b and a lower side frame 225b that are arranged in parallel.

[0026] Each overall lifting slider 226a, 226b, 226c, 226d is composed of a channel steel (channel material) with a U-shaped cross-section. The overall lifting sliders 226a, 226c on the front side are arranged to extend along the vertical direction with the open surface facing the back side (the back facing the front side). The upper ends of the overall lifting sliders 226a, 226c on the front side are fixed to the front ends of the upper side frames 224a, 224b, and the lower ends of the overall lifting sliders 226a, 226c on the front side are fixed to the front ends of the lower side frames 225a, 225b. On the other hand, the overall lifting sliders 226b, 226d on the back side are arranged to extend along the vertical direction with the open surface facing the front side (the back facing the back side). The upper ends of the overall lifting sliders 226b, 226d on the back side are fixed to the back ends of the upper side frames 224a, 224b, and the lower ends of the overall lifting sliders 226b, 226d on the back side are fixed to the back ends of the lower side frames 225a, 225b. As shown in FIG. 5, a pair of guide rollers gr are provided on the back surface of each overall lifting slider 226a, 226b, 226c, 226d. Note that the guide rollers gr provided on the overall lifting sliders 226b, 226d on the back side are not shown. The pair of guide rollers gr are provided at the lower ends of the overall lifting sliders 226a, 226b, 226c, 226d so as to be arranged at a predetermined interval along the vertical direction. Each guide roller gr is configured to be rotatable about a rotation axis (not shown) extending along the depth direction. In addition, a plurality of lock holes rh (see FIG. 5) are provided on the back surfaces of the overall lifting sliders 226a, 226c on the front side. The plurality of lock holes rh are provided at positions above the pair of guide rollers gr. The plurality of lock holes rh are provided so as to be arranged at a predetermined interval along the vertical direction. Each lock hole rh is a circular through hole.

[0027] Each individual lifting guide rail 227a, 227b, 228a, 228b, 229a, 229b is composed of a channel steel (channel material) with a U-shaped cross-section. Each first individual lifting guide rail 227a, 227b is arranged to extend along the vertical direction with the open surface facing forward (the back facing the back side). Each second individual lifting guide rail 228a, 228b is arranged to extend along the vertical direction with the open surface facing forward (the back facing the back side). Each third individual lifting guide rail 229a, 229b is arranged to extend along the vertical direction with the open surface facing backward (the back facing the front side). The upper ends of the individual lifting guide rails 227a, 228a, 229a are fixed to the upper side frame 224a, and the lower ends of the individual lifting guide rails 227a, 228a, 229a are fixed to the lower side 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. Also, the first individual lifting guide rail 227a, the second individual lifting guide rail 228a, and the third individual lifting guide rail 229a are arranged to be arranged at a predetermined interval along the depth direction. The upper ends of the individual lifting guide rails 227b, 228b, 229b are fixed to the upper side frame 224b, and the lower ends of the individual lifting guide rails 227b, 228b, 229b are fixed to the lower side 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. Also, the first individual lifting guide rail 227b, the second individual lifting guide rail 228b, and the third individual lifting guide rail 229b are arranged to be arranged at a predetermined interval along the depth direction. A plurality of lock holes RH (see FIG. 5) are provided on the back surfaces of the individual lifting guide rails 227a, 227b, 228a, 228b, 229a, 229b. The plurality of lock holes RH are provided to be arranged at a predetermined interval along the vertical direction. Each lock hole RH is a circular through hole.

[0028] The connecting frame 223 is composed of a channel steel (channel material) with a U-shaped cross-section. The connecting frame 223 is arranged to extend along the left-right direction with the open surface facing forward (the back facing backward). The connecting frame 223 connects the left frame unit 221 and the right frame unit 222. Specifically, the left end of the connecting frame 223 is fixed to the back end of the upper side frame 224a. Also, the right end of the connecting frame 223 is fixed to the back end of the upper side frame 224b. As a result, the overall lifting frame 220 is configured by integrating the left frame unit 221 and the right frame unit 222 via the connecting frame 223.

[0029] The overall lifting frame 220 is attached to the base frame 210 so as to be able to move up and down. Specifically, the left frame unit 221 is supported (held) so as to be able to move up and down by a pair of left overall lifting guide rails 216a, 216b. That is, the two guide rollers gr provided on the front overall lifting slider 226a are arranged in the guide groove 216c provided on the left overall lifting guide rail 216a. As a result, the front overall lifting slider 226a can slide in the vertical direction along the left overall lifting guide rail 216a (guide groove 216c). Also, the two guide rollers gr provided on the rear overall lifting slider 226b are arranged in the guide groove 216c provided on the left overall lifting guide rail 216b. As a result, the rear overall lifting slider 226b can slide in the vertical direction along the left overall lifting guide rail 216b (guide groove 216c). Similarly, the right frame unit 222 is supported (held) so as to be movable up and down by a pair of right overall lifting guide rails 217a and 217b. That is, the two guide rollers gr provided in the front overall lifting slider 226c are arranged in the guide groove 217c provided in the right overall lifting guide rail 217a. Thereby, the front overall lifting slider 226c is slidable in the vertical direction along the right overall lifting guide rail 217a (guide groove 217c). Also, the two guide rollers gr provided in the rear overall lifting slider 226d are arranged in the guide groove 217c provided in the right overall lifting guide rail 217b. Thereby, the rear overall lifting slider 226d is slidable in the vertical direction along the right overall lifting guide rail 217b (guide groove 217c). As described above, the overall 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 lock mechanisms 218 (a left overall lifting lock mechanism 218 and a right overall lifting lock mechanism 218). And, by the pair of overall lifting lock mechanisms 218, it is possible to lock (fix) the up and down movement of the overall lifting frame 220 with respect to the base frame 210. The left overall lifting lock mechanism 218 is arranged at the upper end of the left overall lifting guide rail 216a. The right overall lifting lock mechanism 218 is arranged at the upper end of the right overall lifting guide rail 217a. Note that the right overall lifting lock mechanism 218 is not shown in the figure. Each overall lifting lock mechanism 218 is composed of an operation lever 218a and a lock shaft 218b. Each operation lever 218a can be operated (displaced) to a lock position or a release position. Each lock shaft 218b is formed in a cylindrical shape and is arranged to extend along the depth direction. When each operation lever 218a is operated to the lock position, the lock shaft 218b protrudes toward the back side via a link mechanism (not shown). On the other hand, when each operation lever 218a is operated to the release position, the lock shaft 218b retracts toward the front side via the link mechanism.

[0031] In the left overall lifting lock mechanism 218, when the operation lever 218a is operated to the lock position, the lock shaft 218b is inserted into one of a plurality of lock holes rh provided in the front overall lifting slider 226a. Thereby, the sliding of the front overall lifting slider 226a with respect to the left overall lifting guide rail 216a is locked. Similarly, in the right overall lifting lock mechanism 218, when the operation lever 218a is operated to the lock position, the lock shaft 218b is inserted into one of a plurality of lock holes rh provided in the front overall lifting slider 226c. Thereby, the sliding of the front overall lifting slider 226c with respect to the right overall lifting guide rail 217a is locked. Thereby, the lifting of the overall lifting frame 220 with respect to the base frame 210 is locked, and the lifting of the overall lifting frame 220 with respect to the base frame 210 becomes impossible. That is, the height of the overall lifting frame 220 is locked (fixed / maintained). In particular, a plurality of lock holes rh are provided in each of the overall lifting sliders 226a and 226c along the vertical direction. Thereby, as shown in FIGS. 2 and 4, it is possible to lock the overall lifting frame 220 at an arbitrary height by selecting / changing the lock hole rh into which each lock shaft 218b is inserted. On one side, in the overall lifting and lowering lock mechanism 218 on the left side, when the operating lever 218a is operated to the release position, the lock shaft 218b is withdrawn from the lock hole rh provided in the overall lifting and lowering slider 226a on the front side. As a result, the lock of the overall lifting and lowering slider 226a on the front side with respect to the left overall lifting and lowering guide rail 216a is released. Similarly, in the overall lifting and lowering lock mechanism 218 on the right side, when the operating lever 218a is operated to the release position, the lock shaft 218b is withdrawn from the lock hole rh provided in the overall lifting and lowering slider 226c on the front side. As a result, the lock of the overall lifting and lowering slider 226c on the front side with respect to the right overall lifting and lowering guide rail 217a is released. As a result, the lock of the overall lifting and lowering frame 220 with respect to the base frame 210 is released, and the overall lifting and lowering frame 220 can be lifted and lowered with respect to the base frame 210.

[0032] In addition, a pair of damper devices da for assisting the lifting and lowering of the overall lifting and lowering frame 220 with respect to the base frame 210 are arranged on the base frame 210. Each damper device da is composed of a double-cylinder damper. In each damper device da, the tip of the piston rod is fixed to the lower horizontal members 212c and 213c, and the tip of the shell case is supported by the lower side frames 225a and 225b via a link mechanism. As a result, it becomes possible to facilitate the lifting and lowering of the overall lifting and lowering frame 220 by the operator. That is, the overall lifting and lowering frame 220 is pressurized upward with respect to the base frame 210 by a pair of damper devices da. As a result, when adjusting the height of the overall lifting and lowering frame 220, it is not necessary to lift the overall lifting and lowering frame 220 manually, and by adjusting the force (the amount of applying body weight) to press down the overall lifting and lowering frame 220, it becomes possible to lift and lower the overall lifting and lowering frame 220. Therefore, the lifting and lowering, height maintenance, locking, etc. of the overall lifting and lowering frame 220 become easy. In particular, when the lock of the overall lifting and lowering frame 220 by the pair of overall lifting and lowering lock mechanisms 218 is released, it is possible to prevent the overall lifting and lowering frame 220 from falling suddenly.

[0033] (Individual lifting frames 231 to 236) Figure 6 is a cross-sectional view of the base frame 237. Here, Figure 6 shows a cross-section orthogonal 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 arranged to extend along the depth direction. Here, in the following description, among the four side surfaces of the base frame 237, the upper side surface is referred to as the "upper surface", the lower side surface is referred to as the "lower surface", and the inner side surface (the game area GE side) is referred to as the "inner surface". As shown in Figure 6, among the four side surfaces of the base frame 237, at least the inner surface is provided with a T-groove tg. In the present embodiment, the T-groove tg is provided on the inner surface and the upper surface among the four side surfaces of the base frame 237. In the example shown in Figure 6, the T-groove tg is provided on each of the four side surfaces of the base frame 237. Each T-groove tg extends linearly along the longitudinal direction of the base frame 237 (the direction in which the base frame 237 extends). Each T-groove tg is provided from one end of the longitudinal direction of the base frame 237 to the other end. Each guide rod 238 is configured in a cylindrical shape. Each guide rod 238 is provided to extend downward from the lower surface of the base frame 237. The pair of guide rods 238 are provided to be arranged at a predetermined interval along the longitudinal direction of the base frame 237. The individual lifting slider 238a is composed of a channel steel (channel material) with a U-shaped cross-section. The individual lifting slider 238a is fixed to the lower end of one of the guide rods 238. The individual lifting slider 238a is arranged to extend along the vertical direction. The width of the individual lifting slider 238a is configured to be narrower than the widths of the individual lifting guide rails 227a, 227b, 228a, 228b, 229a, and 229b.

[0034] In this embodiment, in the left frame unit 221, three sets of individual lifting frames 231 to 233 are attached. The three sets of individual lifting frames 231 to 233 are provided so as to be arranged at a predetermined interval along the depth direction. Each of the individual lifting frames 231 to 233 is attached to the left frame unit 221 so as to be liftable. In particular, the three sets of individual lifting frames 231 to 233 can be lifted individually. Specifically, among the three sets of individual lifting frames 231 to 233, the front individual lifting frame 231 is supported (held) by the left frame unit 221 so as to be liftable. 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 side frame 224a and arranging the individual lifting slider 238a in the first individual lifting guide rail 227a. 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 first individual lifting guide rail 227a in the vertical direction. As a result, the individual lifting frame 231 can be lifted with respect to the left frame unit 221. In particular, the base frame 237 provided in the individual lifting frame 231 can be lifted with respect to the left frame unit 221. Among the three sets of individual lifting frames 231 to 233, the middle individual lifting frame 232 is supported (held) in a vertically movable manner by the left frame unit 221. That is, for the individual lifting frame 232, a pair of guide rods 238 are inserted into guide holes gh provided in the upper side frame 224a, and individual lifting sliders 238a are arranged within the second individual lifting guide rail 228a, whereby it is attached to the left frame unit 221. 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 in the vertical direction along the second individual lifting guide rail 228a. As a result, the individual lifting frame 232 is vertically movable with respect to the left frame unit 221. In particular, the base frame 237 provided in the individual lifting frame 232 is vertically movable with respect to the left frame unit 221. Among the three sets of individual lifting frames 231 to 233, the rear individual lifting frame 233 is supported (held) in a vertically movable manner by the left frame unit 221. That is, for the individual lifting frame 233, a pair of guide rods 238 are inserted into guide holes gh provided in the upper side frame 224a, and individual lifting sliders 238a are arranged within the third individual lifting guide rail 229a, whereby it is attached to the left frame unit 221. 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 in the vertical direction along the third individual lifting guide rail 229a. As a result, the individual lifting frame 233 is vertically movable with respect to the left frame unit 221. In particular, the base frame 237 provided in the individual lifting frame 233 is vertically movable with respect to the left frame unit 221.

[0035] In addition, in the right frame unit 222, three sets of individual elevating frames 234 to 236 are attached. The three sets of individual elevating frames 234 to 236 are provided so as to be arranged at predetermined intervals along the depth direction. Each of the individual elevating frames 234 to 236 is attached to the right frame unit 222 so as to be elevable. In particular, the three sets of individual elevating frames 234 to 236 can be individually elevated and lowered. Specifically, among the three sets of individual elevating frames 234 to 236, the front individual elevating frame 234 is supported (held) by the right frame unit 222 so as to be elevable. That is, for the individual elevating frame 234, a pair of guide rods 238 are inserted into guide holes gh provided in the upper side frame 224b, and an individual elevating slider 238a is disposed in the first individual elevating guide rail 227b, whereby the individual elevating frame 234 is attached to the right frame unit 222. And 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 elevating slider 238a is slidable in the vertical direction along the first individual elevating guide rail 227b. Thereby, the individual elevating frame 234 can be elevated with respect to the right frame unit 222. In particular, the base frame 237 included in the individual elevating frame 234 can be elevated with respect to the right frame unit 222. Among the three sets of individual lifting frames 234 to 236, the middle individual lifting frame 235 is supported (held) in a vertically movable manner by the right frame unit 222. That is, for the individual lifting frame 235, a pair of guide rods 238 are inserted into guide holes gh provided in the upper side frame 224b, and individual lifting sliders 238a are arranged within the second individual lifting guide rail 228b, whereby it is attached to the right frame unit 222. 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 in the vertical direction along the second individual lifting guide rail 228b. Thereby, the individual lifting frame 235 is vertically movable with respect to the right frame unit 222. In particular, the base frame 237 provided in the individual lifting frame 235 is vertically movable with respect to the right frame unit 222. Among the three sets of individual lifting frames 234 to 236, the rear individual lifting frame 236 is supported (held) in a vertically movable manner by the right frame unit 222. That is, for the individual lifting frame 236, a pair of guide rods 238 are inserted into guide holes gh provided in the upper side frame 224b, and individual lifting sliders 238a are arranged within the third individual lifting guide rail 229b, whereby it is attached to the right frame unit 222. 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 in the vertical direction along the third individual lifting guide rail 229b. Thereby, the individual lifting frame 236 is vertically movable with respect to the right frame unit 222. In particular, the base frame 237 provided in the individual lifting frame 236 is vertically movable with respect to the right frame unit 222. As described above, each of the individual lifting frames 231 to 236 is individually attached to the overall lifting frame 220 in a vertically movable manner.

[0036] Here, each individual lifting frame 231 to 236 is configured to include an individual lifting lock mechanism 239. And the individual lifting lock mechanism 239 provided in each individual lifting frame 231 to 236 enables the lifting of the corresponding individual lifting frame 231 to 236 relative to the overall lifting frame 220 to be locked (fixed and maintained). Each individual lifting lock mechanism 239 is configured to include an operation button 239a and a lock shaft 239b. The operation button 239a is attached to the lower surface of the base frame 237. The operation button 239a can be operated (displaced) to a lock position or a release position. Specifically, the operation button 239a is pressed by a compression spring or the like so as to be disposed at the lock position. And the operation button 239a can be operated from the lock position to the release position by being pushed in by an operator. The lock shaft 239b is attached to the individual lifting slider 238a. The lock shaft 239b is formed in a cylindrical shape and is disposed so as to extend along the depth direction. And when the operation button 239a is at the lock position, the lock shaft 239b projects outward from the back surface of the individual lifting slider 238a through a through hole provided in the individual lifting slider 238a. On the other hand, when the operation button 239a is operated to the release state, the lock shaft 239b is immersed inside the back surface of the individual lifting slider 238a.

[0037] In the individual lifting lock mechanism 239 provided in the individual lifting frame 231, when the operation button 239a is disposed at the lock position, the lock shaft 239b is inserted into one of a plurality of lock holes RH provided in the first individual lifting guide rail 227a. Thereby, the sliding of the individual lifting slider 238a with respect to the first individual lifting guide rail 227a is locked. As a result, the raising and lowering of the individual lifting frame 231 with respect to the overall lifting frame 220 is locked, and the raising and lowering of the individual lifting frame 231 with respect to the overall lifting frame 220 becomes impossible. That is, the height of the individual lifting frame 231 is locked (fixed / maintained). In particular, the first individual lifting guide rail 227a is provided with a plurality of locking holes RH along the vertical direction. As a result, as shown in FIGS. 2 and 3, by selecting / modifying the locking hole RH into which the locking shaft 239b is inserted, the individual lifting frame 231 can be locked at an arbitrary height. On the other hand, in the individual lifting lock mechanism 239 provided in the individual lifting frame 231, when the operation button 239a is operated to the release position, the locking shaft 239b is withdrawn from the locking hole RH provided in the first individual lifting guide rail 227a. As a result, the locking of the individual lifting slider 238a with respect to the first individual lifting guide rail 227a is released. As a result, the locking of the individual lifting frame 231 with respect to the overall lifting frame 220 is released, and the raising and lowering of the individual lifting frame 231 with respect to the overall lifting frame 220 becomes possible.

[0038] Here, for the other individual lifting frames 232 to 233, based on the same principle as the individual lifting frame 231, the raising and lowering of the other individual lifting frames 232 to 236, and the locking of the other individual lifting frames 232 to 236 at an arbitrary height are possible. At this time, the individual lifting lock mechanism 239 provided in the individual lifting frame 232 can lock the raising and lowering of the individual lifting frame 232 with respect to the overall lifting frame 220 by locking the sliding of the individual lifting slider 238a with respect to the second individual lifting guide rail 228a. On the other hand, the individual lifting lock mechanism 239 provided in the individual lifting frame 233 can lock the raising and lowering of the individual lifting frame 233 with respect to the overall lifting frame 220 by locking the sliding of the individual lifting slider 238a with respect to the third individual lifting guide rail 229a. On the one hand, the individual lifting lock mechanism 239 provided in the individual lifting frame 234 can lock the lifting of the individual lifting frame 234 with respect to the overall lifting frame 220 by locking the sliding of the individual lifting slider 238a with respect to the first individual lifting guide rail 227b. On the one hand, the individual lifting lock mechanism 239 provided in the individual lifting frame 235 can lock the lifting of the individual lifting frame 235 with respect to the overall lifting frame 220 by locking the sliding of the individual lifting slider 238a with respect to the second individual lifting guide rail 228b. On the one hand, the individual lifting lock mechanism 239 provided in the individual lifting frame 236 can lock the lifting of the individual lifting frame 236 with respect to the overall lifting frame 220 by locking the sliding of the individual lifting slider 238a with respect to the third individual lifting guide rail 229b.

[0039] (Prize Arrangement Mechanism 30) Next, the configuration of the prize arrangement mechanism 30 will be described. FIG. 7 is a perspective view showing an example of the prize arrangement mechanism 30 attached to the base frame unit 20. Inside the housing 10 (particularly, within the area surrounded by the base frame unit 20), a game area GE in which a prize acquisition game is developed is configured. The prize arrangement mechanism 30 is a mechanism for arranging prizes P within the game area GE. That is, the prize arrangement mechanism 30 arranges the prizes P within the game area GE. At this time, as the arrangement mode, various modes such as placing, hanging, and clamping can be selected according to the configuration of the prize arrangement mechanism 30. In particular, in the present embodiment, the prize arrangement mechanism 30 constitutes a prize arrangement area AE and an opening area OE within the game area GE. The "prize arrangement area AE" is an area where the prizes P are arranged. The "opening area OE" is an area where the acquisition of the prize P becomes possible due to the fall of the prize P.

[0040] As shown in FIG. 7, the prize arrangement mechanism 30 is attached to one or a plurality of individual elevating frames 231 to 236 among the six sets of individual elevating frames 231 to 236. At this time, the prize arrangement mechanism 30 is attached to the base frame 237. Note that the prize arrangement mechanism 30 shown in FIG. 7 includes a medium floor frame 310B attached to the individual elevating frame 233, a floor panel 320 attached to the upper surface of the medium floor frame 310B, and a flexible rod 340 spanned between the individual elevating frame 231 and the individual elevating frame 234. Here, the configuration of the prize arrangement mechanism 30 shown in FIG. 7 is an example, and as will be described later, the prize arrangement mechanism 30 can have various configurations. The prize arrangement mechanism 30 is constituted by one constituent member or by combining a plurality of constituent members. In the present embodiment, as constituent members constituting the prize arrangement mechanism 30, one or a plurality of small floor frames 310A, one or a plurality of medium floor frames 310B, one or a plurality of large floor frames 310C, one or a plurality of floor panels 320, various floor parts, one or a plurality of flexible rods 340, etc. are prepared. Then, the prize arrangement mechanism 30 is constituted by combining one or a plurality of these constituent members. Hereinafter, each constituent member will be described.

[0041] (Floor frames 310A, 310B, 310C) FIG. 8 is a perspective view showing the medium floor frame 310B. FIG. 9 is a cross-sectional view taken along the line A-A shown in FIG. 8. FIG. 10 is a perspective view showing a state in which the small floor frame 310A and the medium floor frame 310B are connected. 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 have different sizes. Specifically, in the small floor frame 310A, the medium floor frame 310B, and the large floor frame 310C, the longitudinal dimension (length) of the horizontal frame 311b described later is different. 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 square column shape. Here, in the following description, in a state where the floor frames 310A, 310B, and 310C are placed on a plane, among the four side surfaces of each of the frames 311a and 312b, the upper side surface is referred to as the "upper side surface", the lower side surface is referred to as the "lower side surface", the inner side surface (the center side of the floor frames 310A, 310B, and 310C) is referred to as the "inner side surface", and the outer side surface (the side opposite to the center of the floor frames 310A, 310B, and 310C) is referred to as the "outer side surface". Note that FIGS. 8 and 9 show a state in which a T-groove nut (T-slot nut) described later is inserted into the T-groove TG provided on the upper side surface of each horizontal frame 311b. Therefore, when the T-groove nut (T-slot nut) is removed from each T-groove TG, the T-groove TG becomes the same state as the other T-groove TGs (such as the T-groove TG provided on the upper side surface of each vertical frame 311a). Here, the T-groove nut is a member used for attaching the floor panel 320, various floor parts, etc. to each floor frame 310A, 310B, and 310C. FIGS. 8 and 9 show an example in which a T-groove nut having a dimension substantially the same as the longitudinal dimension of the T-groove TG is used. However, it is possible to use various T-groove nuts having a dimension shorter than the longitudinal dimension of the T-groove TG as the T-groove nut. As shown in FIG. 9, among the four side surfaces of each of the frames 311a and 311b, at least the outer side surface is provided with a T-groove TG. In the present embodiment, the T-groove TG is provided on the outer side surface, the upper side surface, and the lower side surface among the four side surfaces of each of the frames 311a and 311b. In the example shown in FIG. 9, the T-groove TG is provided on each of the four side surfaces of each of the frames 311a and 311b. Each T-groove TG extends linearly along the longitudinal direction of each of the frames 311a and 311b (the direction in which each of the frames 311a and 311b extends). Each T-groove TG is provided from one end on one side in the longitudinal direction of each of the frames 311a and 311b to the other end. Here, the configuration of each T-groove TG is the same as the configuration of each T-groove tg. That is, the shape of the cross-section orthogonal to the longitudinal direction of each T-groove TG is the same as the shape of the cross-section orthogonal 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 is configured to include a connecting member (not shown) and a resin cover (not shown) that covers the connecting member. The connecting member 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 shaft portion 313a formed in a columnar shape, an operation portion 313b fixed to one end of the shaft portion 313a, and a T-groove 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 operation portion 313b, and the central axis of the T-groove nut portion 313c are arranged coaxially. Thereby, by rotating the operation portion 313b, it is possible to rotate the T-groove nut portion 313c via the shaft portion 313a. Here, the T-groove nut portion 313c is formed in a substantially rectangular plate shape in a plan view. In particular, the dimension (length) in the longitudinal direction of the T-groove nut portion 313c is larger than the width of each T-groove TG, tg. On the other hand, the dimension (width) in the direction orthogonal to the longitudinal direction of the T-groove nut portion 313c is smaller than the width of each T-groove TG, tg.

[0043] The floor frames 310A, 310B, 310C are configured by connecting four frames 311a, 311b in an endless (annular) shape by four corner brackets 312. As a result, the floor frames 310A, 310B, 310C become a substantially rectangular frame body (frame portion) in a plan view. In addition, one or a plurality of 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 that penetrates 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 the present embodiment, one or a plurality of through holes h are provided in each of the frames 311a, 311b. And, in each through hole h, one fixing member 313 is attached. 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 through the T-groove TG provided on the inner surface, the through hole h, and the T-groove TG provided on the outer surface. And, the operation portion 313b of each fixing member 313 is arranged 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 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 floor frame 310A, the medium floor frame 310B, and the large floor frame 310C, for the horizontal frame 311b, the dimensions (lengths) in the longitudinal direction are different, and for the vertical frame 311a, the dimensions (lengths) in the longitudinal direction are the same. In the medium floor frame 310B, for the four frames 311a and 311b, the dimensions in the longitudinal direction are the same. As a result, the medium floor frame 310B forms a substantially square frame body in plan view. In the medium floor frame 310B, two fixing members 313 are attached to each of the frames 311a and 311b. On the other hand, in the small floor frame 310A, the dimension of the horizontal frame 311b in the longitudinal direction is smaller than the dimension of the vertical frame 311a in the longitudinal direction. As a result, the small floor frame 310A forms a vertically long substantially rectangular frame body in plan view. In particular, the width of the small floor frame 310A is half of 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 dimension of the horizontal frame 311b in the longitudinal direction is larger than the dimension of the vertical frame 311a in the longitudinal direction. As a result, the large floor frame 310C forms a horizontally long substantially rectangular frame body in plan view. In particular, the width of the large floor frame 310C is three times the width of the medium floor frame 310B. In the large floor frame 310C, two fixing members 313 are attached to each of the frames 311a and 311b.

[0045] Each of the floor frames 310A, 310B, and 310C can be attached to the upper surface or the inner surface of the base frame 237. Each of the floor frames 310A, 310B, and 310C can be attached to the upper surface or the inner surface of the base frame 237 via the fixing member 313. That is, when attaching the floor frames 310A, 310B, and 310C to the upper surface or the inner surface of the base frame 237, first, among the four frames 311a and 311b that constitute the floor frames 310A, 310B, and 310C, the outer surface of any one of the frames 311a and 311b (hereinafter referred to as the "fixed frame") is arranged in a state of facing the upper surface or the inner surface of the base frame 237 (hereinafter referred to as the "fixed surface"). Next, insert the T-groove nut portion 313c of each fixing member 313 provided on the fixed frame into the T-groove tg provided on the fixed surface. At this time, by rotating the operation portion 313b of each fixing member 313 so that the longitudinal direction of the T-groove nut portion 313c and the longitudinal direction of the T-groove tg are aligned, the T-groove nut portion 313c can be inserted into the T-groove tg. Next, rotate the operation portion 313b of each fixing member 313 to rotate the T-groove nut portion 313c by 90° in a predetermined direction. Then, in the T-groove tg, the T-groove nut portion 313c is displaced from a state parallel to the T-groove tg (released state) to a state orthogonal to the T-groove tg (fixed state). As a result, the T-groove nut portion 313c of each fixing member 313 is fixed in the T-groove tg. Thereby, the fixed frame is fixed to the base frame 237 in a state where the outer surface of the fixed frame is in close contact with the fixed surface. In particular, when the T-groove nut portion 313c is displaced to a state orthogonal to the T-groove tg (fixed state), the position of the T-groove nut portion 313c is fixed in the T-groove tg. As a result, it becomes impossible to change the fixing 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 fixing of the position of the T-groove nut portion 313c in the T-groove tg is released. As a result, it becomes possible to change the fixing position of the fixing member 313 in the T-groove tg. As described above, the floor frames 310A, 310B, and 310C are attached to the fixed surface of the base frame 237.

[0046] In particular, on the upper surface of the base frame 237, a T-groove tg is provided extending from one end in the longitudinal direction to the other end. As a result, on the upper surface of the base frame 237, it is possible to fix the fixing member 313 at any position in the longitudinal direction. Therefore, the fixing positions of the floor frames 310A, 310B, 310C with respect to the upper surface of the base frame 237 can be set arbitrarily. Here, when the floor frames 310A, 310B, 310C are attached to the upper surface of the base frame 237, the floor frames 310A, 310B, 310C are arranged to extend upward from the upper surface of the base frame 237. At this time, the upper surface (or the lower surface) of the floor frames 310A, 310B, 310C faces the game area GE side. Similarly, on the inner surface of the base frame 237, a T-groove tg is provided extending from one end in the longitudinal direction to the other end. As a result, on the inner surface of the base frame 237, it is possible to fix the fixing member 313 at any position in the longitudinal direction. Therefore, the fixing positions of the floor frames 310A, 310B, 310C with respect to the inner surface of the base frame 237 can be set arbitrarily. Here, when the floor frames 310A, 310B, 310C are attached to the inner surface of the base frame 237, the floor frames 310A, 310B, 310C are arranged to extend from the inner surface of the base frame 237 toward the game area GE side. At this time, the upper surface (or the lower surface) of the floor frames 310A, 310B, 310C faces upward.

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

[0048] Also, each floor frame 310A, 310B, 310C can be attached to other floor frames 310A, 310B, 310C via a fixing member 313. As a result, it becomes possible to connect a plurality of floor frames 310A, 310B, 310C. At this time, it becomes possible to connect a plurality of floor frames 310A, 310B, 310C of any size. That is, when attaching the first floor frame 310A, 310B, 310C to the second floor frame 310A, 310B, 310C, first, among the four frames 311a, 311b constituting the first floor frame 310A, 310B, 310C, any one of the frames 311a, 311b (hereinafter referred to as "first fixed frame") is arranged in a state where its outer surface faces the upper surface or the outer surface (hereinafter referred to as "fixed surface") of any one of the four frames 311a, 311b (hereinafter referred to as "second fixed frame") constituting the second floor frame 310A, 310B, 310C. Next, insert the T-groove nut portion 313c of each fixing member 313 provided on the first fixing frame into the T-groove TG provided on the fixing surface. At this time, by rotating the operation portion 313b of each fixing member 313 so that the longitudinal direction of the T-groove nut portion 313c coincides with the longitudinal direction of the T-groove TG, the T-groove nut portion 313c can be inserted into the T-groove TG. Next, rotate the operation portion 313b of each fixing member 313 to rotate the T-groove nut portion 313c by 90° in a predetermined direction. Then, in the T-groove TG, the T-groove nut portion 313c is displaced from a state parallel to the T-groove TG (released state) to a state orthogonal to the T-groove TG (fixed state). As a result, the T-groove nut portion 313c of each fixing member 313 is fixed in the T-groove TG. Thereby, the first fixing frame is fixed to the second fixing frame in a state where the outer surface of the first fixing frame is in close contact with the fixing surface of the second fixing frame. In particular, when the T-groove nut portion 313c is displaced to a state orthogonal to the T-groove TG (fixed state), the position of the T-groove nut portion 313c is fixed in the T-groove TG. As a result, it becomes impossible to change the fixing 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 fixing of the position of the T-groove nut portion 313c in the T-groove TG is released. As a result, it becomes possible to change the fixing position of the fixing member 313 in the T-groove TG. Here, when the T-groove nut portion 313c is displaced to a state parallel to the T-groove TG (released state), the first fixing frame can be slid relative to the second fixing frame while the T-groove nut portion 313c remains inserted in the T-groove TG. As a result, it becomes possible to change (adjust) the fixing position of the first fixing frame with respect to the second fixing frame without removing the T-groove nut portion 313c from the T-groove TG. Further, by setting one of the pair of T-groove nuts 313c in a state orthogonal (fixed state) to the T-groove TG and the other T-groove nut 313c in a state parallel (released state) to the T-groove TG, the first fixed frame can be rotated with respect to the second fixed frame about one T-groove nut 313c (fixed member 313) as an axis. As described above, the first floor frames 310A, 310B, 310C are attached to the fixing surfaces of the second floor frames 310A, 310B, 310C.

[0049] In particular, T-grooves TG are provided on the upper surfaces of the respective frames 311a, 311b over the entire length from one end in the longitudinal direction to the other end. As a result, on the upper surfaces of the respective frames 311a, 311b (second fixed frames), the fixing member 313 (the fixing member 313 of the first fixed frame) can be fixed at an arbitrary position in the longitudinal direction. Therefore, the fixing positions of the first floor frames 310A, 310B, 310C with respect to the upper surface of the second fixed frame can be arbitrarily set. Here, when the first floor frames 310A, 310B, 310C are attached to the upper surface of the second fixed frame, the first floor frames 310A, 310B, 310C are arranged to extend upward from the upper surface of the second fixed 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 to intersect. Similarly, on the outer surfaces of each of the frames 311a and 311b, a T-groove TG is provided extending from one end in the longitudinal direction to the other end. As a result, on the outer surfaces of each of the frames 311a and 311b (the second fixed frames), it is possible to fix the fixing member 313 (the fixing member 313 of the first fixed frame) at an arbitrary position in the longitudinal direction. Therefore, it is possible to arbitrarily set the fixing positions of the first floor frames 310A, 310B, and 310C with respect to the outer surface of the second fixed frame. Here, when the first floor frames 310A, 310B, and 310C are attached to the outer surface of the second fixed frame, the first floor frames 310A, 310B, and 310C are arranged to extend outward from the outer surface of the second fixed frame. At this time, the upper surfaces of the first floor frames 310A, 310B, and 310C, and the upper surfaces of the second floor frames 310A, 310B, and 310C are arranged on the same plane.

[0050] As described above, for example, one floor frame 310A, 310B, 310C (the first fixed frame) can be attached to the upper surface or the outer surface of one frame 311a, 311b (the second fixed frame). At this time, the fixing position of one floor frame 310A, 310B, 310C (the first fixed frame) can be adjusted along the longitudinal direction of one frame 311a, 311b (the second fixed frame). Also, two floor frames 310A, 310B, 310C (the first fixed frame) can be attached to the upper surface or the outer surface of one frame 311a, 311b (the second fixed frame). In this case, the fixing member 313 provided on one of the first fixed frames and the fixing member 313 provided on the other first fixed frame are fixed to the T-groove TG (the same T-groove TG) provided on the second fixed frame. For example, as shown in FIG. 10, two small floor frames 310A can be attached to the outer surface of the horizontal frame 311b of one medium-sized floor frame 310B. Further, one floor frame 310A, 310B, 310C (first fixed frame) can be attached so as to span between the upper surfaces or outer surfaces of two frames 311a, 311b (second fixed frames). In this case, of the two fixing members 313 provided on the first fixed frame, one fixing member 313 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. In addition, it is also possible to attach a frame member (hereinafter referred to as "old-type frame member") of the type fixed by screwing described in Patent Document 1 to the floor frames 310A, 310B, 310C. For this, a T-groove nut (T-slot nut) is inserted into the T-groove TG provided on the upper surface or outer surface (fixed surface) of any one of the four frames 311a, 311b constituting the floor frames 310A, 310B, 310C. Then, a screw inserted through a screw hole provided on one side surface of the old-type frame member is fitted into a screw hole provided in the T-groove nut inserted into the T-groove TG provided on the fixed surface. Thereby, it becomes possible to connect the floor frames 310A, 310B, 310C and the old-type frame member.

[0051] (Floor panel 320) FIG. 11 is a perspective view showing the floor panel 320. FIG. 11 shows a state in which the floor panel 320 is attached to the upper surface of the medium-sized floor frame 310B. As shown in FIG. 11, the floor panel 320 is formed in a substantially square flat plate shape in 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 attachment portions (fixing portions) 321 are formed on the upper surface of the floor panel 320. Various floor parts can be attached to each attachment portion 321. The plurality of attachment parts 321 are regularly arranged in a predetermined pattern on the upper surface of the floor panel 320. Specifically, the plurality of attachment parts 321 are arranged in a matrix (row and column pattern) on the upper surface of the floor panel 320. In the present embodiment, 6 rows × 6 columns = 36 attachment parts 321 are arranged on the upper surface of the floor panel 320. The six attachment parts 321 constituting each row are arranged at equal intervals. Also, the six attachment parts 321 constituting each column are arranged at equal intervals. Further, the interval between two adjacent attachment parts 321 in each row (hereinafter referred to as "column interval"), and the interval between two adjacent attachment parts 321 in each column (hereinafter referred to as "row interval") are the same. In particular, the row interval and the column interval can be set according to the intended gameplay. For example, when attaching floor parts to two adjacent attachment parts 321 in each row or each column, and for the claw member 411a described later, realizing a gameplay of approaching the prize P by passing between the floor parts attached to the two attachment parts 321, the row interval and the column interval are set to be less than the size of the prize P and greater than or equal to the width of the claw member 411a. At this time, the narrower the row interval and the column interval, the more difficult it is to access the prize P, and the higher the difficulty level of the prize acquisition game. On the other hand, the wider the row interval and the column interval, the easier it is to access the prize P, and the lower the difficulty level of the prize acquisition game. Or, when attaching floor parts to two adjacent attachment parts 321 in each row or each column, and for the claw member 411a described later, realizing a gameplay that blocks the passage between the floor parts attached to the two attachment parts 321 and allows only a direct approach to the prize P, the row interval and the column interval are set to be less than the size of the prize P and less than the width of the claw member 411a. Thereby, when floor parts are attached to two adjacent attachment parts 321 in each row or each column, the passage between the floor parts attached to the two attachment parts 321 by the claw member 411a is blocked (made impossible), and it becomes possible to improve the difficulty level of the prize acquisition game. In the present embodiment, a plurality of claw members 411a with different widths are prepared as the claw members 411a. And the row pitch and the column pitch 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. Also, twice the row pitch and twice the column pitch 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 attachment parts 321 in each row or each column, the passage between the floor parts attached to the two attachment parts 321 by the widest claw member 411a is blocked (becomes impossible), and the passage between the floor parts attached to the two attachment parts 321 by the narrowest claw member 411a is allowed (becomes possible). On the other hand, when floor parts are attached to two attachment parts 321 with one attachment part 321 opened in each row or each column, the passage between the floor parts attached to the two attachment parts 321 by the widest claw member 411a is allowed (becomes possible). Note that in the present embodiment, on the upper surface of the floor panel 320, a plurality of attachment parts 321 are arranged in a matrix, and the plurality of attachment parts 321 constituting each row and each column are arranged at equal intervals. However, on the upper surface of the floor panel 320, the plurality of attachment parts 321 may be arranged according to other rules. Also, the plurality of attachment parts 321 constituting each row and each column do not have to be arranged at equal intervals. For example, on the upper surface of the floor panel 320, the plurality of attachment parts 321 may be arranged so as to be arranged radially. Alternatively, on the upper surface of the floor panel 320, a plurality of mounting portions 321 may be arranged in a concentric manner. At this time, the intervals between the plurality of mounting portions 321 that form the outer circle and the intervals between the plurality of mounting portions 321 that form the inner circle are made different. For example, the intervals between the plurality of mounting portions 321 that form the outer circle are set wider than the intervals between the plurality of mounting portions 321 that form the inner circle. In particular, the wider the outer circle, the wider the intervals between the plurality of mounting portions 321 that form the circle are set. Thereby, when floor parts are attached to each of the plurality of mounting portions 321 that form each circle, and in a configuration where the prize P can be firmly held as the claw member 411a passes between the plurality of floor parts that form the more inner circle, it becomes possible to make it more difficult for the claw member 411a to pass between the plurality of floor parts that form the circle as the inner circle. Or, the intervals between the plurality of mounting portions 321 that form the outer circle are set narrower than the intervals between the plurality of mounting portions 321 that form the inner circle. In particular, the wider the outer circle, the narrower the intervals between the plurality of mounting portions 321 that form the circle are set. Thereby, when floor parts are attached to each of the plurality of mounting portions 321 that form each circle, and in a configuration where the prize P is pushed out from the center of the floor panel 320 by the claw member 411a, it becomes possible to make it more difficult for the prize P to pass between the plurality of floor parts that form the circle as the outer circle.

[0052] Each mounting portion 321 is configured by fitting a hex nut into a recess (hole portion) provided on the upper surface of the floor panel 320. Here, instead of the hex 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 (hex nut) is lower than the upper surface of the floor panel 320. That is, the upper surface of each mounting portion 321 is concave (sunken / buried / sunken) with respect to the upper surface of the floor panel 320. Thereby, it becomes possible to prevent the claw member 411a from getting caught on each mounting portion 321. Note that the upper surfaces of the respective attachment portions 321 (hexagonal nuts) may be arranged on the same plane as the upper surface of the floor panel 320. Even in such a configuration, it is possible to prevent the claw members 411a from hooking onto the respective attachment portions 321.

[0053] The floor panel 320 can be attached to the upper surfaces (lower surfaces) of the floor frames 310A, 310B, and 310C. At this time, when attaching the 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 surfaces of the two connected small floor frames 310A. On the other hand, one floor panel 320 can be attached to the upper surface of the medium floor frame 310B. On the other hand, three floor panels 320 can be attached side by side to the upper surface of the large floor frame 310C. In particular, by connecting a plurality of floor frames 310A, 310B, and 310C, it is possible to attach a plurality of floor panels 320 side by side to the upper surfaces of the series of floor frames 310A, 310B, and 310C. At this time, the column spacing and the row spacing are configured to be the same through two adjacent floor panels 320. In this embodiment, only the floor panel 320 corresponding to the medium floor frame 310B is prepared. However, it may also be configured such that 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 are prepared. That is, the length and width of the floor panel 320 corresponding to the small floor frame 310A are made the same as the length and width of the small floor frame 310A. Also, the length and width of the floor panel 320 corresponding to the medium floor frame 310B are made 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 made the same as the length and width of the large floor frame 310C. And on the upper surface of the small floor frame 310A, it is possible to attach one floor panel 320 (the floor panel 320 corresponding to the small floor frame 310A). Also, on the upper surface of the medium floor frame 310B, it is possible to attach one floor panel 320 (the floor panel 320 corresponding to the medium floor frame 310B). Also, on the upper surface of the large floor frame 310C, it is possible to attach one floor panel 320 (the floor panel 320 corresponding to the large floor frame 310C). At this time, it may also be configured such that on the upper surface of the medium floor frame 310B, two floor panels 320 (two floor panels 320 corresponding to the small floor frame 310A) can be attached. Also, it may be configured such that on the upper surface of the large floor frame 310C, six floor panels 320 (six floor panels 320 corresponding to the small floor frame 310A) can be attached.

[0054] The floor panel 320 is fixed to the upper surfaces of the floor frames 310A, 310B, and 310C by screwing. 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 surfaces of the floor frames 310A, 310B, and 310C, first, a T-groove nut (T-slot nut) is inserted into the T-groove TG provided on the upper side surfaces of the frames 311a and 311b of the floor frames 310A, 310B, and 310C. Next, the floor panel 320 is placed on the upper surfaces of the floor frames 310A, 310B, and 310C. Then, the screws inserted through the respective screw holes s are fitted into the screw holes provided in the T-groove nut. Thereby, the floor panel 320 is fixed to the upper surfaces of the floor frames 310A, 310B, and 310C. At this time, the upper surface (top surface) of the screw is lower than the upper surface of the floor panel 320. That is, the upper surface of the screw is concave (recessed, buried, sunken) with respect to the upper surface of the floor panel 320. This makes it possible to prevent the claw member 411a from catching on the screw.

[0055] (Various floor parts) FIG. 12 is a perspective view showing various floor parts. Here, in FIG. 12, the state of being attached to the attachment portion 321 of the floor panel 320 is shown for various floor parts. In the present embodiment, as various floor parts, a column part 330, a hemispherical part 331, a conical part 332, a spherical part 333, etc. are prepared. As shown in FIG. 12, the column part 330 is formed in a columnar 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 attachment portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, a configuration is provided such that the claw member 411a cannot enter between the bottom surface of the column part 330 and the upper surface of the attachment portion 321. Thereby, when the column part 330 is attached to the attachment portion 321, the attachment portion 321 is covered by the bottom surface of the column part 330, and it becomes possible to prevent the claw member 411a from catching on the attachment portion 321. A screw portion is provided on the bottom surface of the columnar part 330. Further, a screw hole is provided on the top surface of the columnar part 330. The columnar part 330 can be attached to the upper surface of the floor panel 320 by fitting its screw portion into the attachment portion 321. Also, the columnar part 330 can be attached to the upper surface or the outer surface of the frames 311a and 311b provided in the floor frames 310A, 310B, and 310C via T-groove nuts. In this case, the T-groove nut is inserted into the T-groove TG provided on the upper surface or the outer surface of the frames 311a and 311b, and the screw portion of the columnar part 330 is fitted into the screw hole provided in the T-groove nut. In this embodiment, a plurality of types of columnar parts 330 having different lengths are prepared. In particular, by fitting the screw portion of one columnar part 330 into the screw hole of another columnar part 330, it is possible to connect one columnar part 330 and another columnar part 330 in series. For example, a columnar part 330 having a length of 25.0 [mm] and a columnar part 330 having a length of 62.5 [mm] are prepared. By connecting one or more columnar parts 330 in this way, it is possible to configure floor parts of various lengths such as 25.0 [mm] (25.0 [mm] columnar part 330 × 1 piece), 50.0 [mm] (25.0 [mm] columnar part 330 × 2 pieces), 62.5 [mm] (62.5 [mm] columnar part 330 × 1 piece), 75.0 [mm] (25.0 [mm] columnar part 330 × 3 pieces), 87.5 [mm] (25.0 [mm] columnar part 330 × 1 piece + 62.5 [mm] columnar part 330 × 1 piece), 100.0 [mm] (25.0 [mm] columnar part 330 × 4 pieces), etc.

[0056] The hemispherical part 331 is formed in a hemispherical shape. The hemispherical part 331 is formed of resin, rubber, metal, or the like. In particular, a plurality of hemispherical parts 331 made of different materials may be prepared. At this time, it is assumed that the plurality of hemispherical parts 331 are formed of materials having different friction coefficients. As a result, it is possible to vary the friction coefficient for each hemispherical part 331. As a result, depending on the type of hemispherical part 331 used, the slipperiness of the prize P in contact with the hemispherical part 331 changes, and it is possible to change the difficulty of obtaining the prize P. Also, the outer surface (front surface and outer peripheral surface) of the hemispherical part 331 may be formed by combining a plurality of materials having different friction coefficients. For example, among the outer surfaces of the hemispherical part 331, a predetermined portion may be formed of a first material, and another portion may be formed of a second material having a larger friction coefficient than the first material. As a result, it is possible to vary the friction coefficient according to the site on the outer surface of the hemispherical part 331. As a result, depending on the orientation in which the hemispherical part 331 is installed, the slipperiness of the prize P in contact with the hemispherical part 331 changes, and it is possible to change the difficulty of obtaining the prize P. The diameter of the bottom surface of the hemispherical part 331 is larger than the diameter of the mounting portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, a configuration is adopted in which the claw member 411a does not enter between the bottom surface of the hemispherical part 331 and the upper surface of the mounting portion 321. As a result, when the hemispherical part 331 is attached to the mounting portion 321, the mounting portion 321 is covered by the bottom surface of the hemispherical part 331, and it is possible to prevent the claw member 411a from catching on the 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. Further, the hemispherical part 331 can be attached to the top surface of the columnar part 330 by fitting the screw portion into the screw hole of the columnar part 330.

[0057] The conical part 332 is formed in a conical shape. The conical part 332 is formed of resin, rubber, metal, or the like. In particular, a plurality of conical parts 332 made of different materials may be prepared. In this case, it is assumed that the plurality of conical parts 332 are formed of materials having different friction coefficients. By this, it becomes possible to vary the friction coefficient for each conical part 332. As a result, depending on the type of conical part 332 used, the slipperiness of the prize P in contact with the conical part 332 changes, and it becomes possible to vary the difficulty of obtaining the prize P. Also, the outer surface (surface and outer peripheral surface) of the conical part 332 may be formed by combining a plurality of materials having different friction coefficients. For example, among the outer surface of the conical part 332, a predetermined portion may be formed of a first material, and other portions may be formed of a second material having a larger friction coefficient compared to the first material. By this, it becomes possible to vary the friction coefficient according to the site on the outer surface of the conical part 332. As a result, depending on the orientation in which the conical part 332 is installed, the slipperiness of the prize P in contact with the conical part 332 changes, and it becomes possible to vary the difficulty of obtaining the prize P. The diameter of the bottom surface of the conical part 332 is larger than the diameter of the mounting portion 321 (recess) provided on the upper surface of the floor panel 320. In particular, a configuration is adopted in which the claw member 411a does not enter between the bottom surface of the conical part 332 and the upper surface of the mounting portion 321. By this, when the conical part 332 is attached to the mounting portion 321, the mounting portion 321 is covered by the bottom surface of the conical part 332, and it becomes possible to prevent the claw member 411a from being caught on the mounting portion 321. A screw portion is provided on the bottom surface of the conical part 332. The conical part 332 can be attached to the upper surface of the floor panel 320 by fitting the screw portion into the mounting portion 321. Also, the conical part 332 can be attached to the top surface of the column part 330 by fitting the screw portion into the screw hole of the column part 330.

[0058] The spherical part 333 is composed of a spherical part 333a and a cylindrical part 333b fixed to the bottom of the spherical part 333a. The spherical part 333a is formed in a spherical shape. The spherical part 333a is formed of resin, rubber, metal, or the like. In particular, a plurality of spherical parts 333 with different materials for the spherical part 333a may be prepared. In this case, for the plurality of spherical parts 333, it is assumed that the spherical part 333a is formed of materials with different friction coefficients. Thereby, it becomes possible to vary the friction coefficient of the spherical part 333a for each spherical part 333. As a result, depending on the type of the spherical part 333 used, the slipperiness of the prize P, D-ring, etc. in contact with the spherical part 333a changes, and it becomes possible to change the difficulty of obtaining the prize P. Also, in each spherical part 333, the outer surface (surface and outer peripheral surface) of the spherical part 333a may be formed by combining a plurality of materials with different friction coefficients. For example, among the outer surfaces of the spherical part 333a, a predetermined portion may be formed of a first material, and other portions may be formed of a second material having a larger friction coefficient compared to the first material. Thereby, it becomes possible to vary the friction coefficient according to the site on the outer surface of the spherical part 333a. As a result, depending on the orientation in which the spherical part 333 is installed, the slipperiness of the prize P, D-ring, etc. in contact with the spherical part 333a changes, and it becomes possible to change the difficulty of obtaining the prize P. The cylindrical part 333b is formed in a cylindrical shape. The cylindrical part 333b is formed of an alloy such as stainless steel. The diameter of the bottom surface of the cylindrical part 333b is larger than the diameter of the mounting part 321 (recess) provided on the upper surface of the floor panel 320. In particular, a configuration is adopted in which the claw member 411a does not enter between the bottom surface of the cylindrical part 333b and the upper surface of the mounting part 321. Thereby, when the spherical part 333 is attached to the mounting part 321, the mounting part 321 is covered by the bottom surface of the cylindrical part 333b, and it becomes possible to prevent the claw member 411a from being caught on the mounting part 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 its screw portion to the attachment portion 321. Also, the spherical part 333 can be attached to the top surface of the column part 330 by fitting its screw portion to the screw hole of the column part 330. Also, the spherical part 333 can be attached to the upper side surface or the outer side surface of the frames 311a, 311b provided in the floor frames 310A, 310B, 310C via a T-groove nut. In this case, the T-groove nut is inserted into the T-groove TG provided on the upper side surface or the outer side surface of the frames 311a, 311b, and the screw portion of the spherical part 330 is fitted into the screw hole provided in the T-groove 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 the flexible rod 340. FIG. 14 is a cross-sectional view orthogonal to the central axis of the flexible rod 340. FIG. 15 is a cross-sectional view along the central axis of the flexible rod 340. As shown in FIG. 13, the flexible rod 340 includes a rod portion 341 and ball joint portions 342 attached to each end in the longitudinal direction of the rod portion 341 (the direction in which the rod portion 341 extends). The rod portion 341 is composed of two cylindrical bodies 341a, 341b. That is, the rod portion 341 is configured by inserting (fitting) all or 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 (movable in sliding) with respect to the cylindrical body 341b. At this time, the cylindrical body 341a can be slid (moved in sliding) in the direction of being accommodated inside the cylindrical body 341b (hereinafter referred to as the "accommodation direction") or the direction of being discharged from inside the cylindrical body 341b (hereinafter referred to as the "discharge direction"). When the cylindrical body 341a is slid in the accommodation direction, the rod portion 341 (flexible rod 340) contracts. On the other hand, when the cylindrical body 341a is slid in the discharge direction, the rod portion 341 (flexible rod 340) extends. Thus, by sliding the cylindrical body 341a in the accommodation direction or the discharge direction, it is possible to change (adjust) the longitudinal dimension of the rod portion 341 (flexible rod 340). As shown in FIG. 14, in the present embodiment, the cross section orthogonal to the longitudinal direction of each of the cylindrical bodies 341a and 341b has a teardrop shape. That is, on the outer peripheral 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. Thereby, when supporting the prize P by the outer peripheral surfaces of the cylindrical bodies 341a and 341b, it is possible to change the frictional force acting on the prize P 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 it is possible to change the difficulty of obtaining the prize P. Further, when supporting the prize P by the outer peripheral surfaces of the cylindrical bodies 341a and 341b, it is possible to change the state of supporting the prize P according to the portion supporting the prize P. At this time, the area of contact with the prize P decreases in the order of the flat surface portion, the arc surface portion, and the corner portion (large → small). Therefore, it is possible to stably support the prize P in the order of the flat surface portion, the arc surface portion, and the corner portion (stable → unstable). As a result, it is possible to change the difficulty of obtaining the prize P depending on whether the prize P is supported by the arc surface portion, the flat surface portion, or the corner portion. Note that the cross-section orthogonal to the longitudinal direction of each cylindrical body 341a, 341b can be appropriately changed to a circular shape, a polygonal shape (triangle, quadrilateral, 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-groove nut portion (T-slot nut portion) 345. The ball stud portion 343 includes a shaft portion 343a formed in a columnar shape and a spherical portion 343b fixed to the tip 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 surface and a bottom surface. The main body portion 344a slidably holds (accommodates) the spherical portion 343b therein. Accordingly, in each ball joint portion 342, the ball stud portion 343 can be rotated (rotated in the circumferential direction with the central axis of the ball stud portion 343 as the rotation axis) and rocked (changing the direction and angle in which the central axis of the ball stud portion 343 extends) with respect to the socket portion 344.

[0061] The lock mechanism 344b can lock at least one of the rotation and rocking of the ball stud portion 343 with respect to the socket portion 344. In the present embodiment, the lock mechanism 344b is configured to lock the rotation of the ball stud portion 343 with respect to the socket portion 344 and not lock the rocking of the ball stud portion 343 with respect to the socket portion 344. Note that the lock mechanism 344b may be configured to be able to lock both the rotation and rocking of the ball stud portion 343 with respect 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 lock position or a release position. Here, a slit (not shown) extending along the direction in which the central axis extends is provided on the outer peripheral surface of the main body portion 344a. When the cam lever 344c is operated to the locked position, the interval between the slits provided in the main body portion 344a becomes narrower, and the inner circumference of the main body portion 344a contracts. As a result, the spherical portion 343b is clamped by the inner circumferential surface of the main body portion 344a, and the rotation of the ball stud portion 343 with respect to the socket portion 344 is locked. At this time, the rocking of the ball stud portion 343 with respect to the socket portion 344 is not locked. On the other hand, when the cam lever 344c is operated to the released 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. As a result, the clamping of the spherical portion 343b by the inner circumferential surface of the main body portion 344a is released, and the rotation and rocking of the ball stud portion 343 with respect to the socket portion 344 become possible. The T-groove nut portion 345 is fixed to the bottom surface of the main body portion 344a. The T-groove nut portion 345 is formed in a rectangular plate shape in a plan view. In particular, the dimension (length) in the longitudinal direction of the T-groove nut portion 345 is larger than the width of each T-groove TG, tg. On the other hand, the dimension (width) in the direction orthogonal to the longitudinal direction of the T-groove nut portion 345 is smaller than the width of each T-groove TG, tg.

[0062] Each ball joint portion 342 is attached to the end portion of the rod portion 341 by fitting the shaft portion 343a inside the cylindrical bodies 341a, 341b. At this time, the central axis of the shaft portion 343a and the central axes 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 released position, the rotation and rocking of the rod portion 341 with respect to the T-groove nut portion 345 fixed to the ball joint portion 342 become possible. On the other hand, when the cam lever 344c of each ball joint portion 342 is operated to the locked position, only the rocking of the rod portion 341 with respect to the T-groove nut portion 345 fixed to the ball joint portion 342 becomes possible, and rotation becomes impossible. As described above, with the flexible rod 340, it is possible to change (adjust) the angle of the rod portion 341 with respect to each socket portion 344. Further, with the flexible rod 340, it is possible to change (adjust) the distance between the pair of ball joint portions 342 (T-groove nut portions 345) by contracting or extending the rod portion 341.

[0063] The flexible rod 340 can be attached to the upper surface or the inner surface of the base frame 237. That is, when attaching the flexible rod 340 to the upper surface or the inner surface (hereinafter referred to as the "fixed surface") of the base frame 237, first, the T-groove nut portion 345 provided at the end of the flexible rod 340 is inserted into the T-groove tg provided on the fixed surface of the base frame 237. At this time, by rotating the socket portion 344 so that the longitudinal direction of the T-groove nut portion 345 and the longitudinal direction of the T-groove tg are aligned, the T-groove nut portion 345 can be inserted into the T-groove tg. Next, rotate the socket portion 344 to rotate the T-groove nut portion 345 by 90[°] in a predetermined direction. Then, in the T-groove tg, the T-groove nut portion 345 is displaced from a state parallel to the T-groove tg (released state) to a state orthogonal to the T-groove tg (fixed state). As a result, the T-groove nut portion 345 is fixed in the T-groove tg. Thereby, with the bottom surface of the socket portion 344 (main body portion 344a) in close contact with the fixed surface, the end portion of the flexible rod 340 is fixed to the base frame 237. In particular, when the T-groove nut portion 345 is displaced to a state orthogonal to the T-groove tg (fixed state), the position of the T-groove nut portion 345 is fixed in the T-groove tg. As a result, it becomes impossible to change the fixed position of the socket portion 344 in the T-groove tg. On the other hand, when the T-groove nut portion 345 is displaced to a state parallel to the T-groove tg (released state), the fixing of the position of the T-groove nut portion 345 in the T-groove tg is released. As a result, it becomes possible to change the fixed position of the socket portion 344 in the T-groove tg. As described above, the end of the flexible rod 340 is attached to the fixing surface of the base frame 237. In particular, on the upper surface of the base frame 237, a T-groove tg is provided extending from one end in the longitudinal direction to the other end. As a result, on the upper surface of the base frame 237, it is possible to fix the end of the flexible rod 340 at any position in the longitudinal direction. Therefore, the fixing position of the flexible rod 340 with respect to the upper surface of the base frame 237 can be arbitrarily set. Similarly, on the inner surface of the base frame 237, a T-groove tg is provided extending from one end in the longitudinal direction to the other end. As a result, on the inner surface of the base frame 237, it is possible to fix the end of the flexible rod 340 at any position in the longitudinal direction. Therefore, the fixing position of the flexible rod 340 with respect to the inner surface of the base frame 237 can be arbitrarily set. At this time, when the T-groove nut portion 345 is displaced to a state parallel (released state) to the T-groove tg, it is possible to slide the socket portion 344 with respect to the base frame 237 while the T-groove nut portion 345 is inserted into the T-groove tg. As a result, it is possible to change (adjust) the fixing position of the socket portion 344 with respect to the base frame 237 without removing the T-groove nut portion 345 from the T-groove tg.

[0064] Also, the flexible rod 340 can be attached to the floor frames 310A, 310B, 310C. That is, when attaching the flexible rod 340 to the floor frames 310A, 310B, 310C, first, the T-groove nut portion 345 provided at the end of the flexible rod 340 is inserted into the T-groove TG provided on the upper surface or the outer surface (hereinafter referred to as the "fixed surface") of any one of the four frames 311a, 311b (hereinafter referred to as the "fixed frame") constituting the floor frames 310A, 310B, 310C. At this time, by rotating the socket portion 344 so that the longitudinal direction of the T-groove nut portion 345 and the longitudinal direction of the T-groove TG are aligned, the T-groove nut portion 345 can be inserted into the T-groove TG. Next, rotate the socket portion 344 to rotate the T-groove nut portion 345 by 90° in a predetermined direction. Then, in the T-groove TG, the T-groove nut portion 345 is displaced from a state parallel to the T-groove TG (released state) to a state perpendicular to the T-groove TG (fixed state). As a result, the T-groove nut portion 345 is fixed in the T-groove TG. Thereby, with the bottom surface of the socket portion 344 (main body portion 344a) in close contact with the fixed surface, the end of the flexible rod 340 is fixed to the fixed frame. In particular, when the T-groove nut portion 345 is displaced to a state perpendicular to the T-groove TG (fixed state), the position of the T-groove nut portion 345 is fixed in the T-groove TG. As a result, it becomes impossible to change the fixing position of the socket portion 344 in the T-groove TG. On the other hand, when the T-groove nut portion 345 is displaced to a state parallel to the T-groove TG (released state), the fixing of the position of the T-groove nut portion 345 is released in the T-groove TG. As a result, it becomes possible to change the fixing position of the socket portion 344 in the T-groove TG. As described above, the end of the flexible rod 340 is attached to the fixed surface of the floor frames 310A, 310B, 310C.

[0065] In particular, on the upper surfaces of the respective frames 311a and 311b, a T-groove TG is provided extending from one end in the longitudinal direction to the other end. As a result, at any position in the longitudinal direction on the upper surfaces of the respective frames 311a and 311b, it becomes possible to fix the end of the flexible rod 340. Therefore, it becomes possible to arbitrarily set the fixing position of the flexible rod 340 with respect to the upper surfaces of the respective frames 311a and 311b. Similarly, on the outer surfaces of the respective frames 311a and 311b, a T-groove TG is provided extending from one end in the longitudinal direction to the other end. As a result, at any position in the longitudinal direction on the outer surfaces of the respective frames 311a and 311b, it becomes possible to fix the end of the flexible rod 340. Therefore, it becomes possible to arbitrarily set the fixing position of the flexible rod 340 with respect to the outer surfaces of the respective frames 311a and 311b. At this time, when the T-groove nut portion 345 is displaced to a state parallel (released state) to the T-groove TG, it is possible to slide the socket portion 344 with respect to the frames 311a and 311b while the T-groove nut portion 345 is inserted into the T-groove TG. As a result, it becomes possible to change (adjust) the fixing position of the socket portion 344 with respect to the frames 311a and 311b without removing the T-groove nut portion 345 from the T-groove TG.

[0066] As described above, the flexible rod 340 can be attached so as to span between the base frame 237 of any one of the three sets of individual lifting frames 231 to 233 arranged in the left frame unit 221 and the base frame 237 of any one of the three sets of individual lifting frames 234 to 236 arranged in the right frame unit 222. Further, a flexible rod 340 can be attached so as to span between the base frame 237 of any one of the three sets of individual elevating frames 231 to 233 arranged in the left frame unit 221 and the floor frames 310A, 310B, 310C attached to the base frame 237 of any one of the three sets of individual elevating frames 234 to 236 arranged in the right frame unit 222. Further, 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 one of the three sets of individual elevating frames 231 to 233 arranged in the left frame unit 221 and the base frame 237 of any one of the three sets of individual elevating frames 234 to 236 arranged in the right frame unit 222. Furthermore, 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 one of the three sets of individual elevating frames 231 to 233 arranged in the left frame unit 221 and the floor frames 310A, 310B, 310C attached to the base frame 237 of any one of the three sets of individual elevating frames 234 to 236 arranged in the right frame unit 222. In particular, with the flexible rod 340, it is possible to change (adjust) the slipperiness of the prize P arranged on the rod portion 341 by changing (adjusting) the orientation of the outer peripheral surface of the rod portion 341. At this time, it is possible to make the prize P arranged on the rod portion 341 more difficult to slide when the rod portion 341 is arranged with the corner portion facing upward than when it is arranged with the arc surface portion facing upward. Further, in the flexible rod 340, the rod portion 341 is configured to be telescopically extendable, and in a state where the cam lever 344c is operated to the locked position, the rocking of the rod portion 341 with respect to the socket portion 344 is not locked. Thus, in a state where the cam lever 344c of the flexible rod 340 is operated to the locked position, when the individual lifting frames 234 to 236 over which the flexible rod 340 is spanned are lifted or lowered with respect to the overall lifting frame 220, following this, the angle of the rod portion 341 with respect to the socket portion 344 changes, and as a result, the vertical inclination angle of the flexible rod 340 changes. Therefore, in a state where the cam lever 344c of the flexible rod 340 is operated to the locked position, it is possible to lift or lower the individual lifting frames 234 to 236 over which the flexible rod 340 is spanned with respect to the overall lifting frame 220. At this time, in the flexible rod 340, when the cam lever 344c is operated to the locked position, the frictional force in the rotational direction of the ball stud portion 343 with respect to the socket portion 344 increases, and the rotation of the rod portion 341 (ball stud portion 343) with respect to the socket portion 344 is locked. Thus, even when the individual lifting frames 234 to 236 over which the flexible rod 340 is spanned are lifted or lowered with respect to the overall lifting frame 220 in a state where the cam lever 344c of the flexible rod 340 is operated to the locked position, following this, the rod portion 341 does not rotate with respect to the socket portion 344.

[0067] (Configuration example of the prize arrangement mechanism 30) Next, a configuration example of the prize arrangement mechanism 30 will be described. As described above, in the present 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 the prize arrangement mechanism 30 in various shapes. Hereinafter, an example of the prize arrangement mechanism 30 will be shown.

[0068] (First example) First, the prize arrangement mechanism 30 according to the first example will be described. FIG. 16 is a diagram showing a configuration example of the prize arrangement mechanism 30 according to the first example. FIG. 17 is an enlarged view of the first floor panel 320 constituting the prize arrangement mechanism 30 according to the first example. FIG. 18 is an enlarged view of the second floor panel 320 constituting the prize arrangement mechanism 30 according to the first example. FIG. 19 is a perspective view showing an arrangement example of floor parts in the floor panel 320 according to the first modification. FIG. 20 is a perspective view showing an arrangement example of floor parts in the floor panel 320 according to the second modification. FIG. 21 is a perspective view showing an arrangement example of floor parts in the floor panel 320 according to the third modification. As shown in FIG. 16, the prize arrangement mechanism 30 according to the first example includes, in the game area GE, two prize placement surfaces A and B that can place the prize P (hereinafter referred to as "prize placement surfaces"). The two prize placement surfaces A and B are spaced apart from each other and have different heights. That is, the prize arrangement mechanism 30 according to the first example includes 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 among the three sets of individual lifting frames 231 to 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 provided in the individual lifting frame 231. As a result, the first medium-sized floor frame 310B is arranged to extend from the inner surface of the base frame 237 provided in the individual lifting frame 231 toward the game area GE side. At this time, the first 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 the T-groove tg provided on the inner surface of the base frame 237 provided in the individual lifting frame 231. 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 floor frame 310B is attached to the middle individual lifting frame 235 among the three sets of individual lifting frames 234 to 236 arranged in the right frame unit 222. Specifically, the second medium floor frame 310B is attached to the inner surface of the base frame 237 provided in the individual lifting frame 235. As a result, the second medium floor frame 310B is arranged to extend from the inner surface of the base frame 237 provided in the individual lifting frame 235 toward the game area GE side. At this time, the second medium 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 the T-groove tg provided on the inner surface of the base frame 237 provided in the individual lifting frame 235. As a result, the second medium floor frame 310B is attached to the individual lifting frame 235 in a cantilever state.

[0069] A first floor panel 320 is attached to the upper surface of the first medium 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 to the first prize placement surface A in a predetermined pattern. At this time, the plurality of column parts 330 are of the same type (length). Each column part 330 is attached to the attachment part 321 of the floor panel 320. As a result, as shown in FIG. 17, it becomes possible to place a part of the prize P in a floating state on the first prize placement surface A. That is, on the first prize placement surface A, it becomes possible to support the bottom surface of the prize P using the upper surface of the first floor panel 320 and the tip of the column part 330. Therefore, a part of the bottom surface of the prize P can be made to float with respect to the upper surface of the first floor panel 320. Thus, for example, when placing a box-shaped prize P on the first prize placement surface A, it becomes possible to create a space for inserting the claw member 411a between the upper surface of the first floor panel 320 and the bottom surface of the prize P.

[0070] A second floor panel 320 is attached to the upper surface of the second medium 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. Also, 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 parts are formed on the second prize placement surface B. Each prize placement part is composed of three column parts 330. At this time, among the three column parts 330, two column parts 330 with a short dimension (hereinafter referred to as "short column parts 330") are used, and one column part 330 with a long dimension (hereinafter referred to as "long column parts 330") is used. And each prize placement part is configured by arranging the long column part 330 at a position between the two short column parts 330 and at a position deeper than the two short column parts 330. Each column part 330 is attached to the attachment part 321 of the floor panel 320. As a result, as shown in FIG. 18, it becomes possible to place the prize P in an upright state on the second prize placement surface B. That is, on the second prize placement surface B, each prize placement part can support the prize P in an upright state. At this time, in each prize placement part, the front of the prize P is supported by the two short column parts 330, and the back of the prize P is supported by the one long column part 330. Therefore, for example, when placing a flat bag-shaped prize P on the second prize placement surface B, it becomes possible to arrange the prize P three-dimensionally.

[0071] Here, in the prize arrangement mechanism 30 according to the first example, the first medium floor frame 310B and the second medium floor frame 310B are attached to different individual lifting frames 231, 235. As a result, it is possible to individually adjust the heights of the first prize placement surface A and the second prize placement surface B. That is, when adjusting the heights of the prize placement surfaces A and B, the height of the first prize placement surface A can be adjusted by raising and lowering the individual lifting frames 231 with respect to the overall lifting frame 220. Also, the height of the second prize placement surface B can be adjusted by raising and lowering the individual lifting frame 235 with respect to the overall lifting frame 220. Thereby, the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B can be adjusted. Thereafter, by raising and lowering the overall lifting frame 220 with respect to the base frame 210, the relative positional relationship (height relationship) between the prize gripping portion 410 and each of the prize placement surfaces A and B can be adjusted all at once while maintaining the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B. That is, the overall lifting frame 220 can be raised and lowered with respect to the base frame 210 in a state where the raising and lowering of each of the individual lifting frames 231 to 236 with respect to the overall lifting frame 220 is locked by the individual lifting lock mechanism 239.

[0072] Thus, the prize arrangement mechanism 30 according to the first example is configured. The prize arrangement mechanism 30 according to the first example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, in the game area GE, the prize arrangement area AE is constituted on each of the prize placement surfaces A and B, and the opening area OE is constituted around each of the prize placement surfaces A and B. In particular, in the game area GE, it is possible to constitute a plurality of prize arrangement areas AE that are spaced apart from each other and have different heights. And in the prize arrangement mechanism 30 according to the first example, the prize P placed on each of the prize placement surfaces A and B can be obtained by dropping the prize P from above the prize placement surfaces A and B by the prize gripping portion 410.

[0073] Here, various floor parts can be attached to the upper surfaces (each of the prize placement surfaces A and B) of the respective floor panels 320 according to the type of the prize P. For example, as shown in FIG. 19, when using a sewn package as the prize P, on the upper surface of the floor panel 320, a columnar floor part formed by connecting a plurality of column parts 330 in series is attached. Then, on the upper surface of the floor panel 320, the sewn package is arranged so as to hold the columnar floor part. As a result, on the upper surface of the floor panel 320, the sewn package can be arranged in a standing state or a sitting state. In particular, it is possible to prevent the prize P from rolling left and right due to the interference of the prize gripping part 410. Also, by lifting the prize P higher than the tip of the columnar floor part and removing the holding of the columnar floor part by the prize P, it is possible to provide a gameplay in which the prize P can be obtained. Also, as shown in FIG. 20, when using a cylindrical article as the prize P, on the upper surface of the floor panel 320, a pair of hemispherical parts 331, a pair of conical parts 332, a pair of column parts 330, etc. are attached. As a result, it is possible to prevent the prize P from rolling by the pair of floor parts, and on the upper surface of the floor panel 320, the cylindrical prize P can be arranged in a toppled state. At this time, by changing (adjusting) the height of the pair of floor parts, it is possible to change (adjust) the difficulty of obtaining the prize P. Also, as shown in FIG. 21, when using a spherical article as the prize P, on the upper surface of the floor panel 320, a plurality of floor parts are attached in a predetermined pattern to form a path for guiding the prize P to the opening area OE. As a result, on the upper surface of the floor panel 320, by guiding the prize P along the path, it is possible to drop the prize P 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] (Second Example) Next, the prize arrangement mechanism 30 according to the second example will be described. FIG. 22 is a diagram showing a configuration example of the prize arrangement mechanism 30 according to the second example. As shown in FIG. 22, in the second example, the prize arrangement mechanism 30 forms a pair of prize placement surfaces A and B in the game area GE, and it is possible to place the prize P so as to span the pair of prize placement surfaces A and B. The pair of prize placement surfaces A and B are arranged to be separated from each other via the opening area OE. Also, each of the prize placement surfaces A and B is inclined toward the opening area OE side. That is, the prize arrangement 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 innermost individual lifting frame 233 among the three sets of individual lifting frames 231 to 233 arranged in the left frame unit 221. Specifically, the first small floor frame 310A is attached to the upper surface of the base frame 237 provided in the individual lifting frame 233. As a result, the first small floor frame 310A is arranged to extend upward from the upper surface of the base frame 237 provided in the individual lifting frame 233. At this time, the first 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 thereof to the T-groove tg provided on the upper surface of the base frame 237 provided in the individual lifting frame 233. The second small floor frame 310A is attached to the innermost individual lifting frame 236 among the three sets of individual lifting frames 234 to 236 arranged in the right frame unit 222. Specifically, the second small floor frame 310A is attached to the upper surface of the base frame 237 provided in the individual lifting frame 236. As a result, the second small floor frame 310A is arranged to extend upward from the upper surface of the base frame 237 provided in the individual lifting frame 236. At this time, the second small floor frame 310A is attached to the upper surface of the base frame 237 of the individual lifting frame 236 by fixing two fixing members 313 provided on one side thereof to the T-groove tg provided on the upper surface of the base frame 237.

[0075] The large floor frame 310C is spanned between the first small floor frame 310A (individual lifting frame 233) and the second small floor frame 310A (individual lifting frame 236). Specifically, among the pair of vertical frames 311a constituting the large floor frame 310C, one vertical frame 311a is attached to the upper surface of the horizontal frame 311b constituting the first small floor frame 310A and 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 the T-groove TG provided on the upper surface of the horizontal frame 311b, and the other fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237. Also, among 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 the inner surface of the base frame 237 constituting the individual lifting frame 236. At this time, one of the two fixing members 313 provided on the vertical frame 311a is fixed to the T-groove TG provided on the upper surface of the horizontal frame 311b, and the other fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237. As a result, the large floor frame 310C is arranged in a state where its upper surface is 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, no mounting portion 321 is provided on the upper surface of the flat floor panel fp. 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] Also, the prize arrangement mechanism 30 according to the second example includes 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. And the three medium-sized floor frames 310B connected in a row are bridged between the left frame unit 221 and the right frame unit 222. In the following description, among 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 to 233 arranged in the left frame unit 221. At this time, among the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 231, and the other fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 232. Further, the vertical frame 311a that constitutes the right medium floor frame 310B is attached to the inner surface of the base frame 237 that constitutes the front individual lifting frame 234 and the inner surface of the base frame 237 that constitutes the middle individual lifting frame 235 among the three sets of individual lifting frames 234 to 236 arranged in the right frame unit 222. At this time, among the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 234, and the other fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 235. Furthermore, the base frames 237 of the individual lifting frames 232 and 235 are arranged at a lower position than the base frames 237 of the individual lifting frames 231 and 234. As a result, the three medium floor frames 310B connected in a row are arranged in a state where their upper surfaces are inclined toward the back side. A flat floor panel fp is attached to the upper surfaces of the three medium floor frames 310B connected in a row. Thereby, the first prize placement surface A is configured by the upper surface of the flat floor panel fp. 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, the large floor frame 310C and the three medium floor frames 310B connected in a row are attached to different individual lifting frames 231 to 236. Thereby, it is possible to individually adjust the heights of the first prize placement surface A and the second prize placement surface B. That is, when adjusting the heights of the respective prize placement surfaces A and B, it is possible to adjust the height of the second prize placement surface B by raising and lowering the individual lifting frames 233 and 236 with respect to the overall lifting frame 220. Further, 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, it is possible to change (adjust) the inclination angle of the second prize placement surface B. Also, it is possible to adjust the height of the first prize placement surface A by raising and lowering the individual lifting frames 231, 232, 234, and 235 with respect to the overall lifting frame 220. Further, by changing (adjusting) the positional relationship (height relationship) between the base frames 237 of the individual lifting frames 231 and 234 and the base frames 237 of the individual lifting frames 232 and 235, it is possible to change (adjust) the inclination angle of the first prize placement surface A. Thereby, the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B can be adjusted. Thereafter, by raising and lowering the overall lifting frame 220 with respect to the base frame 210, the relative positional relationship (height relationship) between the prize gripping portion 410 and each prize placement surface can be adjusted collectively while maintaining the relative positional relationship (height relationship) between the first prize placement surface A and the second prize placement surface B. That is, with the individual lifting lock mechanism 239 locking the raising and lowering of each individual lifting frame 231 to 236 with respect to the overall lifting frame 220, it is possible to raise and lower the overall lifting frame 220 with respect to the base frame 210.

[0078] Thus, the prize arrangement mechanism 30 according to the second example is configured. The prize arrangement mechanism 30 according to the second example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, in the game area GE, a prize arrangement area AE is constituted on the pair of prize placement surfaces A and B, and an opening area OE is constituted between the pair of prize placement surfaces A and B. In particular, in the game area GE, it is possible to arrange the prize P so as to span between a pair of prize placement surfaces A and B. And in the prize arrangement mechanism 30 according to the second example, by dropping the prize P supported by the pair of prize placement surfaces A and B into the opening area OE by the prize gripping part 410, it becomes possible to acquire the prize P.

[0079] (Third example) Next, the prize arrangement mechanism 30 according to the third example will be described. FIG. 23 is a diagram showing a configuration example of the prize arrangement mechanism 30 according to the third example. As shown in FIG. 23, the prize arrangement mechanism 30 according to the third example includes two prize suspension parts C and D as parts (hereinafter referred to as "prize suspension parts") capable of suspending the prize P in the game area GE. That is, the prize arrangement mechanism 30 according to the third example is configured to include a large floor frame 310C. The large floor frame 310C is spanned between the left frame unit 221 and the right frame unit 222. Specifically, among 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 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 to 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 the T-groove 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 the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 233. Among the pair of vertical frames 311a that make up the large floor frame 310C, the other vertical frame 311a is attached to the inner surface of the base frame 237 that constitutes the middle individual lifting frame 235 and the inner surface of the base frame 237 that constitutes the rear individual lifting frame 236 among the three sets of individual lifting frames 234 to 236 arranged in the right frame unit 222. At this time, among the two fixing members 313 provided on the vertical frame 311a, one fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 235, and the other fixing member 313 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 236. Furthermore, the base frames 237 of the individual lifting frames 233 and 236 are arranged 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 in a state where its upper surface is inclined toward the rear. That is, among the pair of horizontal frames 311b that make up the large floor frame 310C, the front horizontal frame 311b is arranged at a higher position than the rear horizontal frame 311b.

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

[0081] As described above, the prize arrangement mechanism 30 according to the third example is configured. The prize arrangement mechanism 30 according to the third example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, prize suspension parts C and D are formed in the spherical part 333a of each spherical part 333. And at each prize suspension part C and D, it is possible to suspend the prize P via the D ring dr. Thereby, a prize arrangement area AE is formed below each prize suspension part C and D. Also, an opening area OE is formed below the prize P suspended at each prize suspension part C and D. In particular, in the game area GE, it is possible to arrange the prize P in a state of being suspended above the opening area OE. And in the prize arrangement mechanism 30 according to the third example, the prize gripping portion 410 removes the D ring dr hooked on each prize suspension part C and D from the respective prize suspension parts C and D, thereby enabling the acquisition of the prize P connected to the D ring dr.

[0082] (Fourth example) Next, the prize arrangement mechanism 30 according to the fourth example will be described. FIG. 24 is a diagram showing a configuration example of the prize arrangement mechanism 30 according to the fourth example. As shown in FIG. 24, in the fourth example, the prize arrangement mechanism 30 includes two prize hanging parts C and D as parts (hereinafter referred to as "prize hanging parts") capable of hanging the prize P in the game area GE. Further, in the game area GE, one prize display part E is configured as a part (hereinafter referred to as "prize display part") capable of displaying the prize P. That is, the prize arrangement mechanism 30 according to the fourth example is configured to include a large floor frame 310C. The large floor frame 310C is spanned between the individual lifting frames 233 arranged in the left frame unit 221 and the individual lifting frames 236 arranged in the right frame unit 222. Specifically, among 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, the two fixing members 313 provided on the vertical frame 311a are fixed to the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 233. Also, among 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, the two fixing members 313 provided on the vertical frame 311a are fixed to the T-groove 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. As a result, the upper surface of the flat floor panel fp is arranged horizontally. As described above, the prize display part E is constituted by the upper surface of the flat floor panel fp. And in the prize display part E, it is possible to place the spare prize P. It should be noted that the prize P placed on the prize display part E cannot be acquired by the prize gripping part 410 based on the setting that limits the movement range of the prize gripping part 410.

Here, in the prize acquisition game device 1, one or a plurality of extended base frames 240 are prepared. And each extended base frame 240 can form the base frame unit 20. Each extended base frame 240 has the same configuration as the base frame 237. That is, each extended base frame 240 is formed in a quadrangular prism shape. And on each of the four side surfaces of each extended base frame 240, a T-groove tg is provided. Each T-groove tg extends linearly along the longitudinal direction of the extended base frame 240. Each T-groove tg is provided from one end on the longitudinal direction side of the extended base frame 240 to the other end. Each extended 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. Thereby, each extended base frame 240 is arranged to extend along the left-right direction. Specifically, each extended base frame 240 can be bridged between the front-side end of the base frame 237 of the individual lifting frame 231 and the front-side end of the base frame 237 of the individual lifting frame 234. Also, each extended base frame 240 can be bridged between the rear-side end of the base frame 237 of the individual lifting frame 231 and the rear-side end of the base frame 237 of the individual lifting frame 234.

Also, each extended base frame 240 can span between the rear end of the base frame 237 of the individual lifting frame 233 and the rear end of the base frame 237 of the individual lifting frame 236. Here, connecting fittings (not shown) are fixed to each longitudinal end of each extended base frame 240. And each extended base frame 240 can be attached to the base frame 237 via the connecting fittings. At this time, the connecting fittings are provided with fixing members having the same configuration as the fixing member 313. And each extended base frame 240 can be attached to the base frame 237 by fixing the fixing member to the T-groove tg of the base frame 237.

[0084] In the prize arrangement mechanism 30 according to the fourth example, the first extended base frame 240 spans 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 integrally connected via the first extended base frame 240. Further, a second extended base frame 240 is spanned between the rear end of the base frame 237 of the individual lifting frame 232 and the rear end of the base frame 237 of the individual lifting frame 235. Thereby, the individual lifting frame 232 and the individual lifting frame 235 are integrally connected via the second extended base frame 240.

As a result, the second medium floor frame 310B is arranged in a state where its upper surface is inclined inward in the left-right direction.

[0087] A spherical part 333 is attached to the outer surface of the horizontal frame 311b constituting the first medium 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 above T-groove nut. And at the spherical part 333a of the spherical part 333, the first prize hanging part C is constituted. Here, the fixing position of the spherical part 333 can be appropriately changed (adjusted) along the T-groove TG. On the outer surface of the horizontal frame 311b that constitutes the second medium-sized floor frame 310B, a spherical part 333 is attached. The spherical part 333 is fixed to a T-groove TG provided on the outer surface of the horizontal frame 311b via the above-mentioned T-groove nut. And in the spherical part 333a of the spherical part 333, a second prize suspension part D is constituted.

[0088] Here, in the prize arrangement mechanism 30 according to the fourth example, the first medium-sized floor frame 310B and the second medium-sized floor frame 310B are attached to different individual lifting frames 231, 232, 234, 235. Thereby, it is possible to individually adjust the heights of the first prize suspension part C and the second prize suspension part D. That is, when adjusting the height of the first prize suspension part C, it is possible to adjust the height of the first prize suspension part C by raising and lowering the individual lifting frames 231, 234 with respect to the overall lifting frame 220. Also, by changing (adjusting) the fixing position of the fixing member 313 of the first medium-sized floor frame 310B in the T-groove TG of the first small floor frame 310A, it is possible to change (adjust) the inclination angle of the spherical part 333. Also, when adjusting the height of the second prize suspension part D, it is possible to adjust the height of the second prize suspension part D by raising and lowering the individual lifting frames 232, 235 with respect to the overall lifting frame 220. Also, by changing (adjusting) the fixing position of the fixing member 313 of the second medium-sized floor frame 310B in the T-groove TG of the second small floor frame 310A, it is possible to change (adjust) the inclination angle of the spherical part 333. Thereby, the relative positional relationship (height relationship) among the first prize suspension part C, the second prize suspension part D, and the prize display part E can be adjusted. After that, by raising and lowering the overall lifting frame 220 with respect to the base frame 210, the relative positional relationship (height relationship) among the first prize suspension part C, the second prize suspension part D, and the prize display part E can be maintained, and the relative positional relationship (height relationship) between the prize gripping part 410 and each of the prize suspension parts C and D can be adjusted collectively. That is, with the individual lifting and lowering lock mechanism 239 locking the lifting and lowering of each individual lifting frame 231 to 236 with respect to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered with respect to the base frame 210.

[0089] As described above, the prize arrangement mechanism 30 according to the fourth example is configured. The prize arrangement mechanism 30 according to the fourth example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, in the spherical part 333a of each spherical part 333, the prize suspension parts C and D are constituted. And in each of the prize suspension parts C and D, it is possible to suspend the prize P via the D-ring dr. As a result, a prize arrangement area AE is constituted below each of the prize suspension parts C and D. Also, an opening area OE is constituted below the prize P suspended from each of the prize suspension parts C and D. In particular, in the game area GE, it is possible to arrange the prize P in a state of being suspended above the opening area OE. And in the prize arrangement mechanism 30 according to the fourth example, by removing the D-ring dr hooked on each of the prize suspension parts C and D by the prize gripping part 410 from the respective prize suspension parts C and D, it is possible to acquire the prize P connected to the D-ring dr.

[0090] (Fifth Example) Next, the prize arrangement mechanism 30 according to the fifth example will be described. FIG. 25 is a diagram showing a configuration example of the prize arrangement mechanism 30 according to the fifth example. As shown in FIG. 25, in the prize arrangement mechanism 30 according to the fifth example, in the game area GE, a part capable of supporting the prize P (hereinafter referred to as "prize support part") is configured. Also, in the game area GE, a prize display part E is configured. That is, the prize arrangement mechanism 30 according to the fifth example is configured to include a large floor frame 310C. The large floor frame 310C is spanned between the individual lifting frames 233 arranged in the left frame unit 221 and the individual lifting frames 236 arranged in the right frame unit 222. Specifically, among 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, the two fixing members 313 provided on the vertical frame 311a are fixed to the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 233. Also, among 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, the two fixing members 313 provided on the vertical frame 311a are fixed to the T-groove 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. As a result, the upper surface of the flat floor panel is arranged horizontally. As described above, the prize display part E is constituted by the upper surface of the flat floor panel. And in the prize display part E, it is possible to place the spare prize P. Note that the prize P placed on the prize display part E cannot be acquired by the prize gripping part 410 based on the setting that limits the movement range of the prize gripping part 410.

[0091] In addition, the prize arrangement mechanism 30 according to the fifth example includes a pair of flexible rods 340. The pair of flexible rods 340 is spanned between the individual lifting frames 232 arranged on the left frame unit 221 and the individual lifting frames 234 arranged on the right frame unit 222. Specifically, the socket portion 344 provided at one end of each flexible rod 340 is attached to the inner surface of the base frame 237 constituting the individual lifting frame 232. At this time, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 232. Also, 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-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 constituting the individual lifting frame 234. In particular, the pair of flexible rods 340 is 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 substantially parallel at a predetermined interval. Furthermore, the base frame 237 of the individual lifting frame 232 is arranged at a higher position than the base frame 237 of the individual lifting frame 234. As a result, one end of the pair of flexible rods 340 is arranged at a position deeper than the other end, so that they are arranged in an inclined state in the depth direction. Also, one end of the pair of flexible rods 340 is arranged at a higher position than the other end, so that they are arranged in an inclined state in the vertical direction. At this time, in each flexible rod 340, the rod portion 341 is configured to be telescopic. Further, the rod portion 341 can be rotated (rotated circumferentially about the central axis of the rod portion 341 as the rotation axis) and rocked (changing the direction and angle in which the central axis of the rod portion 341 extends) with respect to each socket portion 344. As a result, each flexible rod 340 can be arranged at an arbitrary position and angle. Therefore, each flexible rod 340 can be arranged in a state of being inclined in the depth direction and the vertical direction.

[0092] Here, in the prize arrangement mechanism 30 according to the fifth example, by raising and lowering the individual lifting frames 232 and 234 with respect to the overall lifting frame 220, it is possible to change (adjust) the inclination angle in the vertical direction of each flexible rod 340. At this time, in each flexible rod 340, the rod portion 341 is configured to be telescopic. Further, in each flexible rod 340, when the cam lever 344c is operated to the lock position, the rotation of the rod portion 341 with respect to the socket portion 344 is locked, but the rocking of the rod portion 341 with respect 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 (in a state where the rotation of the rod portion 341 with respect to the socket portion 344 is locked), by raising and lowering the individual lifting frames 232 and 234 with respect to the overall lifting frame 220, it is possible to change (adjust) the inclination angle in the vertical direction of each flexible rod 340. At this time, as the individual lifting frames 232 and 234 are raised and lowered (followed) with respect to the overall lifting frame 220, the rod portion 341 expands and contracts, and the angle of the rod portion 341 with respect to each socket portion 344 changes. Further, by changing (adjusting) the fixed position of the T-groove nut portion 345 of each flexible rod 340 in the T-groove tg of each base frame 237, it is possible to change (adjust) the inclination angle in the depth direction of each flexible rod 340. Thereafter, by raising and lowering the overall lifting frame 220 with respect to the base frame 210, the relative positional relationship (height relationship) between the prize gripping part 410 and each flexible rod 340 can be adjusted all at once while maintaining the inclination angle of each flexible rod 340. That is, with the individual lifting lock mechanisms 239 locking the lifting and lowering of the respective individual lifting frames 231 to 236 with respect to the overall lifting frame 220, the overall lifting frame 220 can be raised and lowered with respect to the base frame 210.

[0093] As described above, the prize arrangement mechanism 30 according to the fifth example is configured. The prize arrangement mechanism 30 according to the fifth example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, a pair of flexible rods 340 constitute a prize support part. And it is possible to support the prize P by a pair of flexible rods 340 (prize support part). Thereby, a prize arrangement area AE is formed on the pair of flexible rods 340. Also, an opening area OE is formed below the pair of flexible rods 340. In particular, when arranging a plurality of prizes P on the pair of flexible rods 340, it is possible to arrange the positions of the plurality of prizes P to be different in the depth direction and the vertical direction. Thereby, it is possible to arrange the plurality of prizes P three-dimensionally. And in the prize arrangement mechanism 30 according to the fifth example, the prize P supported by the prize support part can be dropped from the prize support part by the prize gripping part 410, so that the prize P can be acquired.

[0094] (Sixth Example) Next, the prize arrangement mechanism 30 according to the sixth example will be described. FIG. 26 is a diagram showing a configuration example of the prize arrangement mechanism 30 according to the sixth example. As shown in FIG. 26, the prize arrangement mechanism 30 according to the sixth example has a prize support part in the game area GE. That is, the prize arrangement 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 provided in the individual lifting frame 232. Thereby, the medium-sized floor frame 310B is arranged so as to extend from the inner surface of the individual lifting frame 232 toward the game area GE side. 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 the T-groove tg provided on the inner surface of the base frame 237. Thereby, the medium-sized floor frame 310B is attached to the individual lifting frame 232 in a cantilever state. In addition, a floor panel 320 is attached to the upper surface of the medium-sized floor frame 310B.

[0095] The first flexible rod 340 is spanned between the vertical frame 311a of the medium-sized floor frame 310B and the individual lifting frame 234 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-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove TG provided on the outer surface of the vertical frame 311a of the medium-sized floor frame 310B. Also, the socket portion 344 provided at the other end of the first flexible rod 340 is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 234. At this time, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 234. The second flexible rod 340 is spanned between the vertical frame 311a of the medium floor frame 310B 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 floor frame 310B. At this time, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove TG provided on the outer surface of the vertical frame 311a of the medium floor frame 310B. Also, the socket portion 344 provided at the other end of the second flexible rod 340 is attached to the inner surface of the base frame 237 that constitutes the individual lifting frame 235. At this time, the T-groove nut portion 345 fixed to the socket portion 344 is fixed to the T-groove tg provided on the inner surface of the base frame 237 that constitutes the individual lifting frame 235.

[0096] In particular, the first flexible rod 340 and the second flexible rod 340 are spanned between the medium floor frame 310B and the individual lifting frames 234 and 235 so as to extend in different directions from each other. Here, the base frame 237 of the individual lifting frame 234 is arranged 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 arranged at a higher position than the base frame 237 of the individual lifting frame 232. As a result, one end of the first flexible rod 340 is disposed at a position in front of the other end, so that it is disposed in an inclined state in the depth direction. Further, one end of the first flexible rod 340 is disposed at a lower position than the other end, so that it is disposed in an inclined state in the vertical direction. Also, one end of the second flexible rod 340 is disposed at a position behind the other end, so that it is disposed in an inclined state in the depth direction. Further, one end of the second flexible rod 340 is disposed at a higher position than the other end, so that it is disposed in an inclined state in the vertical direction. At this time, in each flexible rod 340, the rod portion 341 is configured to be stretchable and contractible. Further, the rod portion 341 can be rotated (rotated in the circumferential direction about the central axis of the rod portion 341) and swung (changing the direction and angle in which the central axis of the rod portion 341 extends) with respect to each socket portion 344. As a result, each flexible rod 340 can be disposed at an arbitrary position and angle. Therefore, each flexible rod 340 can be disposed in an inclined state in the depth direction and the vertical direction.

[0097] Here, in the prize arrangement mechanism 30 according to the sixth example, by raising and lowering the individual lifting frame 234 with respect to the overall lifting frame 220, it is possible to change (adjust) the inclination angle in the vertical direction of the first flexible rod 340. Also, by raising and lowering the individual lifting frame 235 with respect to the overall lifting frame 220, it is possible to change (adjust) the inclination angle in the vertical direction of the second flexible rod 340. At this time, in each flexible rod 340, the rod portion 341 is configured to be telescopically extendable. Further, in each flexible rod 340, when the cam lever 344c is operated to the locked position, the rotation of the rod portion 341 with respect to the socket portion 344 is locked, but the swinging of the rod portion 341 with respect to the socket portion 344 is not locked. Thus, for each flexible rod 340, with the cam lever 344c operated to the locked position (with the rotation of the rod portion 341 with respect to the socket portion 344 locked), by raising and lowering the individual lifting frames 234 and 235 with respect to the overall lifting frame 220, it is possible to change (adjust) the inclination angle in the vertical direction of each flexible rod 340. At this time, in accordance with (following) the raising and lowering of the individual lifting frames 234 and 235 with respect to the overall lifting frame 220, the rod portion 341 expands and contracts, and the angle of the rod portion 341 with respect to each socket portion 344 changes. Also, by changing (adjusting) the fixing position of the T-groove nut portion 345 of the first flexible rod 340 in the T-groove tg of the base frame 237 of the individual lifting frame 234, it is possible to change (adjust) the inclination angle in the depth direction of the first flexible rod 340. Furthermore, by changing (adjusting) the fixing position of the T-groove nut portion 345 of the second flexible rod 340 in the T-groove tg of the base frame 237 of the individual lifting frame 235, it is possible to change (adjust) the inclination angle in the depth direction of the second flexible rod 340. Thereafter, by raising and lowering the overall lifting frame 220 with respect to the base frame 210, it is possible to collectively adjust the relative positional relationship (height relationship) between the prize gripping portion 410 and each flexible rod 340 while maintaining the inclination angle of each flexible rod 340. That is, with the individual lifting lock mechanism 239 locking the raising and lowering of each of the individual lifting frames 231 to 236 with respect to the overall lifting frame 220, it is possible to raise and lower the overall lifting frame 220 with respect to the base frame 210.

[0098] Thus, the prize arrangement mechanism 30 according to the sixth example is configured. The prize arrangement mechanism 30 according to the sixth example constitutes a prize arrangement area AE and an opening area OE in the game area GE. That is, a pair of flexible rods 340 constitutes a prize support part. And it is possible to support the prize P by the pair of flexible rods 340 (prize support part). At this time, the bottom surface of the prize P is supported by the first flexible rod 340, and the back surface of the prize P is supported by the second flexible rod 340. Thereby, it becomes possible to arrange the prize P in an upright state. As described above, a prize arrangement area AE is constituted on the pair of flexible rods 340. Also, an opening area OE is constituted below the pair of flexible rods 340. And in the prize arrangement mechanism 30 according to the sixth example, by dropping the prize P supported by the prize support part by the prize gripping part 410 from the prize support part, it becomes possible to acquire the prize P.

[0099] (Crane unit 40) Next, the configuration of the crane unit 40 will be described. The crane unit 40 includes a prize gripping part 410, a moving device 420 that moves the prize gripping part 410 in the horizontal direction, and a lifting device 430 that raises and lowers the prize gripping part 410. The prize gripping part 410 is attached to the bottom surface of the lifting device 430 via a telescopic support part 413. The prize gripping part 410 includes a pair of arms 411 and an opening / closing device 412 that opens and closes the pair of arms 411. Each arm 411 is formed in a substantially L-shaped rod shape. A claw member 411a is attached to the lower end of each arm 411. The opening / closing device 412 includes an opening / closing motor m1 and an opening / closing mechanism (not shown). In the opening / closing device 412, by driving the opening / closing motor m1, it is possible to open and close the pair of arms 411 via the opening / closing mechanism. And the prize gripping part 410 can grip the prize P by opening and closing the pair of arms 411.

[0100] The mobile 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 the 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 the Y-direction rail Ly. The lifting device 430 is slidable along the Y-direction rail Ly. The lifting device 430 is moved along the Y-direction rail Ly by driving the Y-direction motor m3. The lifting device 430 includes a reel (not shown) capable of feeding out or winding up a wire, and a lifting motor m4 for driving the reel. The tip of the wire is attached to the prize gripping part 410. Thus, by driving the reel by the lifting motor m4 and feeding out the wire, the prize gripping part 410 can be lowered. Also, by driving the reel by the lifting motor m4 and winding up the wire, the prize gripping part 410 can be raised. As described above, in the crane unit 40, by driving each of the motors m2, m3, and m3, the prize gripping part 410 can be moved in the left-right direction, the depth direction, and the up-down direction. Also, by driving the opening / closing motor m1, the pair of arms 411 can be opened and closed.

[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, etc. The control unit 51 is composed of 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 necessary for the progress of the prize acquisition game based on various detection signals input from the control panel 13, program data stored in the storage unit 52, etc. The storage unit 52 is composed of a non-volatile memory or the like. Program data necessary for the progress of the prize acquisition game is stored in the storage unit 52. Here, in the prize acquisition game device 1, an X position detection means 53 for detecting the position of the prize gripping part 410 in the X direction (left - right direction), a Y position detection means 54 for detecting the position of the prize gripping part 410 in the Y direction (depth direction), a Z position detection means 55 for detecting the position of the prize gripping part 410 in the Z direction (up - down direction), etc. are arranged. And detection signals output in response to the pressing operations of the respective operation buttons 16a, 16b, detection signals output by the respective position detection means 53, 54, 55, etc. are input to the control unit 51.

[0103] When the control unit 51 detects the insertion of a coin into the coin insertion slot 14, it starts the prize acquisition game. During the prize acquisition game, first, the input of the 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, and the prize gripping part 410 is moved along 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, and the prize gripping part 410 is moved along the depth direction. Then, when the movement along the depth direction of the prize gripping unit 410 is completed, the lifting motor m4 is driven. After the prize gripping unit 410 is lowered to a predetermined height, the opening / closing motor m1 is driven to close the pair of arms 411. Then, after the prize gripping unit 410 is raised to a predetermined height, the prize gripping unit 410 is moved to a predetermined position (opening area OE). Then, at the predetermined position, the opening / closing motor m1 is driven to open the pair of arms 411. Thereafter, the prize gripping unit 410 is moved to the home position, and the current prize acquisition game ends.

[0104] (Modification example) As described above, the embodiments of the present invention have been described. However, in the above embodiments, various modifications can be made. For example, in the above embodiment, the overall lifting frame 220 may be configured to be movable along the depth direction with respect to the base frame 210. For example, the base frame 210 is provided with a mechanism for moving the overall lifting frame 220 along the depth direction and a locking mechanism capable of locking the movement of the overall lifting frame 220 along the depth direction. Specifically, a member that integrates the pair of left overall lifting guide rails 216a and 216b and a member that integrates the pair of right overall lifting guide rails 217a and 217b are provided. Also, a mechanism is provided that allows the integrated pair of left overall lifting guide rails 216a and 216b to move along the depth direction with respect to the intermediate horizontal member 212b and the lower horizontal member 212c, and a mechanism is provided that allows the integrated pair of right overall lifting guide rails 217a and 217b to move along the depth direction with respect to the intermediate horizontal member 213b and the lower horizontal member 213c. Further, as the locking mechanism, a mechanism similar to the overall lifting lock mechanism 218 or a latch mechanism is provided. With such a configuration, by releasing the lock by the locking mechanism, the six sets of individual lifting frames 231 to 236 attached to the overall lifting frame 220 so as to be liftable can be collectively pulled out to the front side with respect to the base frame 210. As a result, the operator can configure the prize arrangement mechanism 30 with the six sets of individual lifting frames 231 to 236 pulled out to the front side, and it becomes possible to simplify the configuration of the prize arrangement mechanism 30. After the configuration of the prize arrangement mechanism 30 is completed, the six sets of individual lifting frames 231 to 236 are pushed into the back side with respect to the base frame 210 all at once and arranged in their original positions, and locked by the locking mechanism.

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

[0106] In the above embodiment, the base frame 237 is formed in a quadrangular prism shape. That is, the cross section orthogonal to the longitudinal direction of the base frame 237 is a quadrangle. And on each of the four side surfaces of the base frame 237, a T-groove tg is provided. However, the base frame 237 may be formed in other polygonal prism shapes such as a triangular prism, a pentagonal prism, or a hexagonal prism. That is, the cross section orthogonal to the longitudinal direction of the base frame 237 may be other polygons such as a triangle, a pentagon, or a hexagon. And a T-groove tg may be provided on each side surface of the base frame 237. By adopting such a configuration, when the floor frames 310A, 310B, and 310C are attached to the base frame 237, the floor frames 310A, 310B, and 310C can be angled with respect to the horizontal plane.

[0107] In addition, in the above embodiment, in the overall lifting frame 220, a T-groove may be provided. For example, T-grooves are provided on the inner side surfaces of the upper side frames 224a and 224b. At this time, the T-grooves are provided so as to extend along the upper side frames 224a and 224b. Also, the configuration of the T-grooves is the same as the configuration of each T-groove tg, TG. That is, the shape of the cross section orthogonal to the longitudinal direction of each T-groove is the same as the shape of the cross section orthogonal to the longitudinal direction of each T-groove tg, TG. In particular, the dimensions (opening width, bottom width, depth) of each T-groove are the same as the dimensions (opening width, bottom width, depth) of each T-groove 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, in the base frame 237, a pair of through holes penetrating in the vertical direction are provided, and a pair of guide rods 238 provided in the individual lifting frames 231 to 236 are inserted into the pair of through holes.

[0108] In addition, in the above embodiment, the floor frames 310A, 310B, and 310C are configured as substantially rectangular frame bodies in plan view. However, the floor frames 310A, 310B, and 310C may be configured as frame bodies of other polygons such as substantially triangular, substantially pentagonal, and substantially hexagonal in plan view.

[0109] In addition, in the above embodiment, the floor frames 310A, 310B, and 310C are configured as substantially rectangular frame bodies (frame portions) in plan view. However, the floor frames 310A, 310B, and 310C may be configured as substantially lattice-shaped (ladder-shaped) frame bodies (frame portions) in plan view. For example, the floor frames 310A, 310B, and 310C may be configured as a substantially lattice-shaped (ladder-shaped) frame body (frame portion) including a pair of horizontal frames 311b and three or more vertical frames 311a spanned between the pair of horizontal frames 311b. At this time, the three or more vertical frames 311a extend parallel to each other. In particular, in the large floor frame 310C, in addition to the vertical frames 311a spanned at each longitudinal end of the pair of horizontal frames 311b, the vertical frames 311a may be spanned at a substantially middle portion in the longitudinal direction of the pair of horizontal frames 311b. With such a configuration, it is possible to increase the locations where the floor panel 320, the flexible rod 340, etc. can be attached.

[0110] Also, in the above embodiment, each of the frames 311a and 311b is formed in a quadrangular prism shape. That is, the cross section orthogonal to the longitudinal direction of each of the frames 311a and 311b is a quadrilateral. And T-grooves TG are provided on each of the four side surfaces of each of the frames 311a and 311b. However, each of the frames 311a and 311b may be formed in other polygonal prism shapes such as a triangular prism shape, a pentagonal prism shape, or a hexagonal prism shape. That is, the cross section orthogonal to the longitudinal direction of each of the frames 311a and 311b may be other polygons such as a triangle, a pentagon, or a hexagon. And T-grooves TG may be provided on each side surface of each of the frames 311a and 311b. By adopting such a configuration, when the floor frames 310A, 310B, and 310C are attached to the base frame 237, it is possible to angle the floor frames 310A, 310B, and 310C with respect to the horizontal plane.

[0111] Also, 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 screwing. 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, claw pieces). That is, a plurality of hook pieces are provided on the lower surface of the floor panel 320. Each hook piece is provided so as to extend downward from the lower surface of the floor panel 320. The lower end portion of each hook piece is bent outward. When attaching the floor panel 320 to the upper surfaces of the floor frames 310A, 310B, and 310C, the lower end portions of the hook pieces are hooked on the T-grooves TG provided on the inner side surfaces of the frames 311a and 311b of the floor frames 310A, 310B, and 310C. This makes it possible to fix the floor panel 320 to the upper surfaces of the floor frames 310A, 310B, and 310C. Alternatively, the floor panel 320 may be configured to be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by one-touch joints (couplers). 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. Also, in the hole provided on the upper surface of the floor panel 320, the shaft portion of the fastener is inserted. 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, by inserting the plug portion into the socket portion provided in the frames 311a and 311b, the plug portion is locked (fixed) within the socket portion. This fixes the floor panel 320 to the floor frames 310A, 310B, and 310C. Also, by operating the release ring provided in the socket portion, the locking of the plug portion by the socket portion is released. Alternatively, the floor panel 320 may be configured to be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by T-slot nuts having screw heads. In this case, a fixture 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. Also, in the hole portion provided on the upper surface of the floor panel 320, the shaft portion of the fixture is inserted. At this time, the screw head is disposed on the upper surface side of the floor panel 320, and the T-slot nut is disposed on the lower surface side of the floor panel 320. Then, after inserting the T-slot nut into the T-slot TG, the T-slot nut is fixed within the T-slot TG by rotating the screw head with a driver or the like. Alternatively, the floor panel 320 may be configured to be attached to the upper surfaces of the floor frames 310A, 310B, and 310C by screw portions (bolt legs) provided on the lower surface of the floor panel 320. In this case, in the frames 311a and 311b of the floor frames 310A, 310B, and 310C, hole portions through which the screw portions provided on the lower surface of the floor panel 320 are inserted are provided. Then, through the hole portions, the lower end portions of the screw portions penetrating from the upper surface side to the lower surface side of the frames 311a and 311b are fixed with a fixing plate sandwiched therebetween and a wing nut or the like.

[0112] Also, 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] Also, in the above embodiment, on the upper surface of the floor panel 320, the row spacing and column spacing of the plurality of attachment portions 321 are each narrower than the width of the claw member 411a. As a result, when floor parts are attached to two adjacent attachment portions 321 in each row or each column, passage between the floor parts attached to the two attachment portions 321 by the claw member 411a is blocked. However, on the upper surface of the floor panel 320, the row spacing and column spacing of the plurality of mounting portions 321 may be configured to be wider than the width of the claw member 411a, respectively. By this, when floor parts are attached to two adjacent mounting portions 321 in each row or each column, the claw member 411a enables passage between the floor parts attached to the two mounting portions 321.

[0114] Also, in the above embodiment, the floor frames 310A, 310B, 310C and the floor panel 320 (or the flat floor panel fp) are configured as individual 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] Also, in the above embodiment, the floor panel 320 is formed in a substantially square flat plate shape in plan view. However, the floor panel 320 may be configured in a three-dimensional shape. For example, the floor panel 320 may be configured in a quadrangular pyramid shape, a frustum of a quadrangular pyramid shape, a shape with a triangular prism laid on its side, etc. In such a configuration, a plurality of mounting portions 321 are provided on the surface (inclined surface or upper surface) of the floor panel 320.

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

[0117] Also, in the above embodiment, in the flexible rod 340, the cross-section orthogonal to the longitudinal direction of each cylindrical body 341a, 341b is in a teardrop shape. However, in the flexible rod 340, the cross-section orthogonal to the longitudinal direction of each cylindrical body 341a, 341b can be appropriately changed to a circular shape, a polygonal shape (triangle, quadrilateral, pentagon, hexagon), etc.

[0118] Also, in the above embodiment, in the flexible rod 340, a T-groove nut portion 345 is provided on the bottom surface of the socket portion 344 (main body portion 344a). However, in the flexible rod 340, a configuration in which the T-groove nut portion 345 is not provided on the bottom surface of the socket portion 344 (main body portion 344a) may also be acceptable. 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 hole portions are provided on the inner side surface of the panel member. Then, the flexible rod 340 is attached to the panel member by inserting the socket portion 344 into the hole portion. Thereby, for example, it becomes possible to arrange the flexible rod 340 so as to span between the hole portions of the panel members attached to the base frame 237 of the individual lifting frame 231 and the hole portions of the panel members attached to the base frame 237 of the individual lifting frame 234.

[0119] In the above-described embodiment, each mounting portion 321 is configured such that a hex nut is fitted into a recess (hole portion) provided on the upper surface of the floor panel 320. Further, screw portions are provided on the bottom surfaces of various floor parts (such as the column part 330, the hemispherical part 331, the conical part 332, the spherical part 333, etc.). Then, by fitting the screw portion to the mounting portion 321, various floor parts are attached to the mounting portion 321. However, a configuration in which various floor parts are attached to the mounting portion 321 by a one-touch joint (coupler) may also be adopted. Specifically, for each mounting portion 321, it is configured by fitting a socket portion into a recess (hole portion) provided on the upper surface of the floor panel 320. Further, a plug portion that fits into the socket portion is provided on the bottom surface (lower end portion) of various floor parts. Then, by inserting (fitting) the plug portion into the socket portion, the plug portion is locked (fixed) within the socket portion, and various floor parts are attached to the mounting portion 321. Also, by operating a release ring provided on the plug portion, the locking of the plug portion by the socket portion is released, and it becomes possible to remove various floor parts from the mounting portion 321.

[0120] In the above-described embodiment, the floor panel 320 is configured to be attached to the floor frames 310A, 310B, 310C. Specifically, the floor panel 320 is configured to be attached to the T-grooves TG of the floor frames 310A, 310B, 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 the T-groove tg of the base frame 237.

[0121] (Operation of the Premium Acquisition Game Device 1) The flexible rod 340 constitutes a prize arrangement mechanism 30 for arranging prizes P within the game area GE. Further, the flexible rod 340 includes a rod portion 341 and socket portions 344 (T-groove nut portions 345) provided at respective end portions of the rod portion 341. In particular, the angle of the rod portion 341 with respect to the socket portion 344 (T-groove nut portion 345) can be changed. Accordingly, with the flexible rod 340, the angle of the rod portion 341 with respect to the socket portion 344 (T-groove nut portion 345) can be changed (adjusted) to various angles. Therefore, the rod portion 341 can be arranged at various angles, and the configuration of the prize arrangement mechanism 30 can be diversified. Also, with the flexible rod 340, the socket portion 344 (T-groove nut portion 345) can be attached to a T-groove tg provided in the base frame 237 of the prize acquisition game device 1. Accordingly, the attachment position of the socket portion 344 (T-groove nut portion 345) can be adjusted along the T-groove tg. Also, with the flexible rod 340, the rod portion 341 is configured to be telescopically extendable. Accordingly, the length of the rod portion 341 can be changed (adjusted), and the configuration of the prize arrangement mechanism 30 can be further diversified.

[0122] Also, with the flexible rod 340, the cross-section of the rod portion 341 (the cross-section orthogonal to the longitudinal direction) is teardrop-shaped. Accordingly, when supporting the prize P by the outer peripheral surface of the rod portion 341, the frictional force acting on the prize P can be changed depending on whether the prize P is supported by the arc surface portion, the flat surface portion, or the corner portion (tip portion). As a result, the ease of sliding 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 it becomes possible to change the difficulty of acquiring the prize P. Also, when supporting the prize P by the outer peripheral surface of the rod portion 341, it is possible to change the state of supporting the prize P according to the portion that supports the prize P. At this time, the contact area with the prize P increases in the order of the flat portion, the arc surface portion, and the corner portion (large → small). Therefore, it becomes possible to stably support the prize P in the order of the flat portion, the arc surface portion, and the corner portion (stable → unstable). As a result, it becomes possible to change the difficulty of obtaining the prize P depending on whether the prize P is supported by the arc surface portion, the flat portion, or the corner portion. Further, the flexible rod 340 includes a lock mechanism 344b that locks the rotation of the rod portion 341 with respect to the socket portion 344 (T-groove nut portion 345). This makes it possible to prevent a situation where it becomes easy to obtain the prize P due to the rotation of the rod portion 341. Further, in the flexible rod 340, it is possible to change (swing) the angle of the rod portion 341 with respect to the socket portion 344 (T-groove nut portion 345) in a state where the rotation of the rod portion 341 with respect to the socket portion 344 (T-groove nut portion 345) is locked by the lock mechanism 344b. This makes it possible to simplify the configuration of the prize arrangement mechanism 30. As described above, in the prize acquisition game device 1, it is possible to diversify the configuration of the prize arrangement mechanism 30.
