DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, an example will be described in which the prize game device according to the present invention is applied to a prize game device 1 capable of executing a prize game. The "prize acquisition game" is a game in which the player (user) operates the operation unit 16 to operate the prize moving unit 210, causing the prize P placed in the game area GE to drop into the opening OE, thereby allowing the player to acquire the prize P. The "prize P" may be either an item that is given to the player upon acquisition, or an item that is not given to the player upon acquisition and can be exchanged for another item (an item given to the player) after acquisition.

[0012] (Configuration of 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 prize game device 1 as seen from above, and Fig. 2 is a perspective view showing the prize game device 1 as seen from the side. 1 shows an example in which one prize game device 1 is configured in one housing 10. However, a plurality of prize game devices 1 may be configured in one housing 10. As shown in Figures 1 and 2, the prize acquisition game device 1 is composed of a housing 10, a crane unit 20, a floor unit 30, a partition unit 40, a prize replenishment unit 50, an opening / closing door unit 60, a display unit 70, and a control board 80 (see Figure 35).

[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, there are a game area (play area) GE where a prize acquisition game is played, and a display area DE where prizes P are displayed. The game area GE is an area (region) that can be reached by an arm 241 of the prize moving unit 210, which will be described later. On the other hand, the display area DE is an area (region) that cannot be reached by the arm 241 of the prize moving unit 210. In this embodiment, the display area DE is configured on the back side of the game area GE. The housing 10 is configured to include an upper housing 11 and a lower housing 12.

[0014] The front, back, left side, and right side of the upper housing 11 are each made of a transparent plate material such as glass or acrylic plate, which allows the player to see the game area GE configured inside the housing 10 from outside the housing 10. The front of the upper housing 11 is configured with a sliding door (not shown) that can be opened and closed, allowing an operator (manager) to place and move prizes P in the game area GE by opening the sliding door of the upper housing 11.

[0015] 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 touch panel display 15, and an operation unit 16. A player can insert coins into the coin slot 14. By inserting coins into the coin slot 14, the player can acquire credits for playing prize games. Note that an electronic money payment device using a storage medium such as a prepaid card or credit card may be provided, allowing the player to acquire credits by paying with electronic money. The touch panel display 15 has a function of displaying various images and a function of accepting operational inputs from a user (or an operator). Specifically, the touch panel display 15 includes a touch panel 15a (see FIG. 35) and a display unit 15b (see FIG. 35). The touch panel 15a is an input device such as a capacitance type or a pressure-sensitive type, and accepts operational inputs from a user's finger, a touch pen, or the like. The display unit 15b is realized by a liquid crystal display, an organic EL (Electro-Luminescence) display, or the like. Various information such as the remaining number of credits acquired by a player is displayed on the display unit 15b. That is, each time credits are acquired by inserting a coin into the coin slot 14, the remaining number of credits displayed on the display unit 15b increases. Furthermore, each time a prize acquisition game is played, the remaining number of credits displayed on the display unit 15b decreases.

[0016] The operation unit 16 accepts operations by the player. The operation unit 16 is configured to include a joystick 16a and operation buttons 16b. The joystick 16a can be operated by tilting it by the player. The joystick 16a accepts operations to move the prize moving unit 210 in horizontal directions (left and right directions and front and back directions) during the prize acquisition game. The operation buttons 16b can be operated by the player by pressing them. The operation buttons 16b accept operations to start a prize acquisition action, which will be described later, during the prize acquisition game. Furthermore, a prize outlet 17 that communicates with the opening OE is provided on the front of the lower housing 12. Prizes P that drop into the opening OE are stored (guided) into the prize storage section CS. A player can then remove the prize P stored in the prize storage section CS through the prize outlet 17 and win the removed prize P. A prize acquisition sensor 17a (see FIG. 35) is disposed inside the prize storage section CS. The prize acquisition sensor 17a outputs a predetermined detection signal to the control board 80 in response to detection of a prize P that has dropped from the opening OE (detection of the acquisition of a prize P). An opening / closing door 19 is provided on the front surface of the lower housing 12. Inside the opening / closing door 19, various control boards (such as the control board 80) are arranged.

[0017] 2, a pair of lifting frame units 100 are disposed inside the lower housing 12. Each lifting frame unit 100 is attached to the lower housing 12. Each lifting frame unit 100 includes a base frame 110 and a lifting mechanism (not shown) that lifts and lowers the base frame 110. The base frame 110 is formed in a substantially rectangular prism shape. The base frame 110 is disposed so as to extend in the front-to-rear direction. In the following description, of the four sides of the base frame 110, the upper side will be referred to as the "upper side," the lower side will be referred to as the "lower side," and the side on the inside (the side facing the game area GE) will be referred to as the "inner side." A T-groove tg is provided on at least the inner surface of the four side surfaces of the base frame 110. In this embodiment, of the four side surfaces of the base frame 110, the T-groove tg is provided on the inner surface and the upper surface. Each T-slot tg extends linearly along the longitudinal direction (direction in which the base frame 110 extends) of the base frame 110. Each T-slot tg is provided from one end of the base frame 110 to the other end in the longitudinal direction. The base frame 110 is attached to the lower housing 12 via a lifting mechanism. The base frame 110 can be raised and lowered in the vertical direction by the lifting mechanism. Each lifting frame unit 100 is provided with a locking mechanism (not shown) that can lock the base frame 110 from rising and falling relative to the lower housing 12. Each lifting frame unit 100 is capable of locking or unlocking the base frame 110 from rising and falling relative to the lower housing 12 using the locking mechanism. In this embodiment, the locking mechanism includes an unlocking lever. By pulling the unlocking lever up to the unlocking position, the base frame 110 is unlocked from the lower housing 12, allowing the base frame 110 to rise and fall relative to the lower housing 12. On the other hand, by pushing the unlocking lever down to the locking position, the base frame 110 is locked to the lower housing 12, preventing the base frame 110 from rising and falling relative to the lower housing 12. In this embodiment, one of the pair of lifting frame units 100 is disposed at the left end of the lower housing 12 (the left end of the game area GE), and the other lifting frame unit 100 is disposed at the right end of the lower housing 12 (the right end of the game area GE). The pair of lifting frame units 100 can individually raise and lower the base frame 110. In this case, the height of the base frame 110 of each lifting frame unit 100 can be adjusted to any height. By attaching various members (rods, panels, etc.) to the T-grooves tg of each base frame 110, it is possible to configure a mechanism for placing prizes P within the game area GE.

[0018] (Crane Unit 20) Next, the configuration of the crane unit 20 will be described. FIG. 3 is a perspective view showing the prize acquisition game device 1 as seen from below. FIG. 4 is a perspective view showing the prize moving section 210 in a state where each arm 241 is arranged in the open position. FIG. 5 is a perspective view showing the prize moving section 210 in a state where each arm 241 is arranged in the closed position. FIG. 6 is a front view showing the arm unit 240 according to a modified example in a state where each arm 241 is arranged in the open position. FIG. 7 is a front view showing the arm unit 240 shown in FIG. 6 in a state where the metal plate 263 has been removed. FIG. 8 is a front view showing the arm unit 240 according to a modified example in a state where each arm 241 is arranged in the closed position. FIG. 9 is a front view showing the arm unit 240 shown in FIG. 8 in a state where the metal plate 263 has been removed. 4 and 5 show the prize moving section 210 with the catcher case 211 removed. As shown in Figure 3, the crane unit 20 is composed of a prize moving section 210, a horizontal moving device 220 that moves the prize moving section 210 horizontally, and a lifting device 230 that raises and lowers the prize moving section 210.

[0019] The horizontal movement device 220 includes a pair of X-direction rails Lx, a Y-direction rail Ly, an X-direction motor m1 (see FIG. 35), and a Y-direction motor m2 (see FIG. 35). The pair of X-direction rails Lx are attached to the top surface (inside) of the upper housing 11. The X-direction rails Lx extend linearly along the left-right direction. The Y-direction rail Ly is attached to a pair of X-direction rails Lx. Specifically, one end of the Y-direction rail Ly is supported by one of the X-direction rails Lx, and the other end of the Y-direction rail Ly is supported by the other X-direction rail Lx. The Y-direction rail Ly is slidable along the pair of X-direction rails Lx. The Y-direction rail Ly extends linearly in the front-to-rear direction. The Y-direction rail Ly is moved along the X-direction rails Lx by driving an X-direction motor m1. The driving of the X-direction motor m1 is controlled by a control board 80. The lifting device 230 is attached to a Y-direction rail Ly. The lifting device 230 is slidable along the Y-direction rail Ly. The lifting device 230 is moved along the Y-direction rail Ly by driving a Y-direction motor m2. The driving of the Y-direction motor m2 is controlled by the control board 80. The lifting device 230 is configured to include a reel (not shown) that can feed out or wind up the wire, and a lifting motor m3 (see Figure 35) that drives the reel. The tip of the wire is attached to the prize moving section 210. This makes it possible to drive the reel with the lifting motor m3 to feed out the wire, thereby lowering the prize moving section 210. In addition, it is possible to lift the prize moving section 210 by driving the reel with the lifting motor m3 and winding up the wire. At this time, the prize moving section 210 can be raised and lowered between an elevated position and a preset lowered position. The driving of the lifting motor m3 is controlled by the control board 80. As described above, in the crane unit 20, by driving the motors m1, m2, and m3, it is possible to move the prize moving section 210 in the left-right direction, the front-rear direction, and the up-down direction.

[0020] The prize moving section 210 is attached to the bottom surface of the lifting device 230 via an extendable support section (not shown). As shown in Figures 4 and 5, the prize moving section 210 is configured to include a catcher case 211 (see Figure 3), a base member 212, and three arm units 240. In this embodiment, the prize moving section 210 is configured as a three-claw type having three arm units 240. However, the prize moving section 210 may be configured as a two-claw type having two arm units 240. Alternatively, the prize moving section 210 may be configured as a single-claw type having one arm unit 240. The catcher case 211 is a substantially cylindrical casing. The base member 212 and the three arm units 240 are housed inside the catcher case 211. At this time, the tip side of the arm 241 of each arm unit 240 protrudes to the outside of the catcher case 211 through a through-hole provided in the side surface of the catcher case 211. The base member 212 is formed from a metal plate such as stainless steel. The lower end of a wire extending from a reel of the lifting device 230 is connected to the upper surface of the base member 212. This makes it possible to raise and lower the base member 212 (prize moving section 210) in accordance with the wire being let out or taken up by the lifting device 230.

[0021] Each arm unit 240 is attached to the base member 212. In this case, the three arm units 240 are attached to the base member 212 so that the arms 241 are spaced at equal angular intervals (120° intervals in this embodiment). The three arm units 240 have the same configuration. Each arm unit 240 includes a base member 242, an opening / closing motor m4, a power transmission unit 243, an arm holding portion 244, an arm 241, a potentiometer 245, and an arm locking mechanism 246. The base member 242 is formed from a metal plate such as stainless steel. The opening / closing motor m4 is attached to the power transmission unit 243. In this embodiment, a stepping motor is used as the opening / closing motor m4. The driving of the opening / closing motor m4 is controlled by the control board 80. The power transmission unit 243 is attached to the base member 242. The power transmission unit 243 includes a power transmission mechanism that transmits the power of the opening / closing motor m4 to the arm holding portion 244 (a rotation shaft 244a described later).

[0022] The base end of a rotating shaft 244a is attached to the arm holding portion 244. The arm holding portion 244 is attached to the power transmission unit 243 via the rotating shaft 244a. The arm holding portion 244 is provided with an attachment portion (not shown) to which the base end of the arm 241 is attached. The attachment portion is formed in a rectangular tube shape, and the base end of the arm 241 can be inserted (fitted) into the attachment portion. The arm holding portion 244 can be displaced (rotated) around the rotating shaft 244a between a closed position (see FIG. 5) and an open position (see FIG. 4). As a result, the arm 241 attached to the arm holding portion 244 can be displaced between the closed position (see FIG. 5) and the open position (see FIG. 4) in accordance with the displacement (rotation) of the arm holding portion 244. The arm 241 is formed in a substantially L-shaped rod shape. The shape of the arm 241 can be changed as needed, such as an arc shape, a wave shape, a flat plate shape, a hook shape, etc. A metal claw member 241a is attached to the tip end (lower end) of the arm 241. The potentiometer 245 is attached to the front side of the power transmission unit 243. The potentiometer 245 is configured with a variable resistor. The potentiometer 245 detects the opening degree (rotational position / rotation angle) of the arm holding portion 244 (arm 241). That is, the potentiometer 245 outputs a detection signal corresponding to the opening degree (rotational position / rotation angle) of the rotary shaft 244a to the control board 80. Then, based on the detection signal input from each potentiometer 245, the processing unit 81 of the control board 80 detects the opening degree (rotational position / rotation angle) of the arm holding portion 244 (arm 241) corresponding to that potentiometer 245.

[0023] The arm lock mechanism 246 includes a solenoid 251 and a cam 252 . The solenoid 251 is attached to the base member 242. When the solenoid 251 is not energized (excited), the plunger 251a falls by its own weight and is positioned at the protruding position (see FIG. 4), and when the solenoid 251 is energized, the plunger 251a is retracted upward and is positioned at the retracted position (see FIG. 5). The cam 252 is attached to the tip of the rotary shaft 244a. The cam 252 rotates together with the rotary shaft 244a as the rotary shaft 244a rotates. The cam 252 has a recess 252a formed on its outer circumferential surface. In the arm lock mechanism 246, the recess 252a (engaging portion) engages with the tip end (engaged portion) of the plunger 251a, thereby making it possible to lock (prevent / lock) the rotation of the arm 241 (arm holding portion 244) relative to the base member 242. Specifically, as shown in FIG. 4, in the arm lock mechanism 246, when the arm 241 is disposed in the open position, the recess 252a is located below the plunger 251a. As a result, when the opening / closing motor m4 is driven (excited) with the solenoid 251 de-energized and the arm 241 rotates to the open position, the plunger 251a falls into the recess 252a due to its own weight and is disposed in the protruding position. Then, the recess 252a engages with the tip of the plunger 251a, thereby locking (preventing or locking) the rotation of the arm 241 toward the closed position. As a result, even when the excitation of the opening / closing motor m4 is stopped, the arm 241 remains disposed in the open position. 5, when the solenoid 251 is energized, the plunger 251a is retracted to the retracted position, and the engagement of the plunger 251a with the recessed portion 252a is released. This unlocks the rotation of the arm 241, and by driving (exciting) the opening / closing motor m4, the arm 241 can be rotated toward the closed position.

[0024] In this embodiment, during an attract state, which will be described later, the prize moving section 210 is placed in a home position. In the home position, the prize moving section 210 is placed in a raised position, and in each arm unit 240, the arm 241 is placed in an open position with the excitation of the opening / closing motor m4 stopped. At this time, in this embodiment, in each arm unit 240, the arm lock mechanism 246 locks the rotation of the arm 241, so that the arm 241 can be maintained in the open position without exciting the opening / closing motor m4. As a result, in the prize moving section 210, the three arms 241 are placed in an open state, which can attract the attention of surrounding users. Furthermore, during the execution of the prize acquisition game, when the prize moving section 210 descends to the descending position due to the prize acquisition operation described below, the arm lock mechanism 246 in each arm unit 240 releases the lock on the rotation of the arm 241. This allows the arm 241 to be rotated from the open position to the closed position by driving the opening / closing motor m4. Furthermore, when the arm 241 in each arm unit 240 has rotated to the open position at the end of the prize acquisition operation, the arm lock mechanism 246 locks the rotation of the arm 241. This makes it possible to maintain the state in which the arm 241 is disposed in the open position even if the excitation of the opening / closing motor m4 is stopped following the end of the prize acquisition operation. In this embodiment, an arm lock mechanism 246 that maintains the arm 241 in the open position is provided in the prize moving section 210. This makes it easy to maintain the arm 241 in the open position during the attract state. In addition, in this embodiment, the arm lock mechanism 246 can be switched between a locked state in which the arm 241 is maintained in the open position (a state in which the plunger 251a is located in the protruding position and the recess 252a is engaged with the tip of the plunger 251a), and a released state in which this state is released (a state in which the plunger 251a is located in the retracted position). This makes it possible to more reliably maintain the state in which the arm 241 is located in the open position. Furthermore, in this embodiment, the arm lock mechanism 246 is configured to include a solenoid 251 and a cam 252 having a recess 252a that engages with the plunger 251a of the solenoid 251. This allows the arm lock mechanism 246 to be configured with a simple structure.

[0025] Here, each arm unit 240 may have a configuration in which an arm lock mechanism 260 is disposed instead of the arm lock mechanism 246 . As shown in FIGS. 6 to 9, the arm lock mechanism 260 includes a ball plunger 261 and a crank member 262. A ball (not shown) biased in a protruding direction by a spring (not shown) is provided at the tip of ball plunger 261. Ball plunger 261 is attached to base member 242 via metal plate 263. At this time, ball plunger 261 is capable of causing the ball to protrude and retract toward the rear side. The crank member 262 is formed in a rectangular column shape. The base end of the crank member 262 is attached to the tip end of the rotary shaft 244a. The tip end side of the crank member 262 can swing in conjunction with the rotation of the rotary shaft 244a. A recess 262a is provided at the tip end of the crank member 262. In the arm lock mechanism 260, the recess 262a (engaging portion) engages with the ball (engaged portion) of the ball plunger 261, thereby making it possible to lock (prevent / lock) the rotation of the arm 241 (arm holding portion 244) relative to the base member 242. 6 and 7, in the arm lock mechanism 260, when the arm 241 is disposed in the open position, the recess 262a engages with the ball of the ball plunger 261. As a result, even if the excitation of the opening / closing motor m4 is stopped, the recess 262a engages with the ball of the ball plunger 261, so that the rotation of the arm 241 toward the closed position is locked (prevented or locked), and the state in which the arm 241 is disposed in the open position is maintained. Also, as shown in Figures 8 and 9, by driving (exciting) the opening / closing motor m4 and rotating the arm 241 toward the closed position, the driving force of the opening / closing motor m4 disengages the recess 262a from the ball of the ball plunger 261, making it possible to rotate the arm 241 toward the closed position. As a result, in the attract state, when the prize moving section 210 is located at the home position, the arm 241 is located at the open position with the excitation of the opening / closing motor m4 stopped in each arm unit 240. At this time, in each arm unit 240, the arm lock mechanism 260 locks the rotation of the arm 241, so that the arm 241 can be maintained in the open position without exciting the opening / closing motor m4. In this embodiment, the arm lock mechanism 260 includes a ball plunger 261 and a crank member 262 having a recess 262a that engages with the ball of the ball plunger 261. This allows the arm lock mechanism 260 to be configured with a simple structure.

[0026] (Floor unit 30) Next, the configuration of the floor unit 30 will be described. Fig. 10 is a perspective view showing the floor unit 30 in a first state, Fig. 11 is a perspective view showing the floor unit 30 in a second state, and Fig. 12 is a perspective view showing the floor unit 30 in a third state. As shown in FIGS. 10 to 12, the floor unit 30 includes a sliding floor 310 and two detachable floors 320. The sliding floor 310 is formed in the shape of a substantially rectangular flat plate in a plan view. The sliding floor 310 is attached to the lower housing 12. The sliding floor 310 is capable of sliding in the left-right direction. Specifically, rollers 309 (see FIGS. 13 to 15) are provided at each longitudinal end of the sliding floor 310. A front frame 311 is provided on the inner wall surface on the front side of the lower housing 12. The front frame 311 extends in the left-right direction from the left end to the right end of the lower housing 12. A floor rail (not shown) is provided on the rear side of the front frame 311. The floor rail extends along the front frame 311. A rear frame 312 is provided on the inner wall surface on the rear side of the lower housing 12. The rear frame 312 extends in the left-right direction from the left end to the right end of the lower housing 12. A floor rail 313 is provided on the front side of the rear frame 312. The floor rail 313 extends along the rear frame 312. The sliding floor 310 is attached to the lower housing 12 by having the rollers 309 on one side (front side) slidably supported by the floor rails of the front frame 311, and the rollers 309 on the other side (rear side) slidably supported by the floor rails 313 of the rear frame 312. This allows the sliding floor 310 to slide left and right inside the lower housing 12. Each detachable floor 320 is formed in the shape of a substantially rectangular flat plate in a plan view. Each detachable floor 320 is configured to be detachable from the lower housing 12. Specifically, each detachable floor 320 can be attached to the lower housing 12 by bridging the upper surface of the front frame 311 and the upper surface of the rear frame 312.

[0027] In this embodiment, a surface (hereinafter referred to as a "prize placing section AE") on which prizes P can be placed is configured in the game area GE. In this case, the prize placing section AE is configured on the upper surface of the sliding floor 310 (detachable floor 320). In particular, in this embodiment, it is possible to change the size of the prize placement section AE by changing the combination of the position of the slide floor 310 and the presence or absence of the two detachable floors 320. In other words, it is possible to change the size of the opening OE by changing the combination of the position of the slide floor 310 and the presence or absence of the two detachable floors 320. In this embodiment, the configuration of the floor unit 30 can be changed among a first state, a second state, and a third state. As shown in FIG. 10, in the floor unit 30 in the first state, the sliding floor 310 is disposed in the left position, and two removable floor pieces 320 are attached to the right side of the sliding floor 310. As a result, the prize placement section AE is formed by the upper surface of the sliding floor 310 and the upper surfaces of the two removable floor pieces 320. In particular, the top surface of the prize storage section CS is defined by the lower surface of the sliding floor 310 and the lower surfaces of the two removable floor pieces 320 (part of the opening leading to the prize storage section CS is blocked). As a result, an opening OE is formed on the left side of the sliding floor 310. Here, in the floor unit 30 in the first state, the area of the prize placement section AE is larger than the area of the opening OE. In addition, in the first state of the floor unit 30, the left end of the prize placement section AE is located to the left of the right end of the prize removal opening 17 in the left-right direction (the left end of the prize placement section AE is located above the prize removal opening 17, and the prize placement section AE covers the top of the prize removal opening 17). As shown in FIG. 11 , in the floor unit 30 in the second state, the sliding floor 310 is disposed in the center position (position to the right of the left position), and one removable floor piece 320 is attached to the right side of the sliding floor 310. As a result, the prize placement section AE is formed by the upper surface of the sliding floor 310 and the upper surface of the single removable floor piece 320. As a result, in the floor unit 30 in the second state, the prize placement section AE is narrower (its dimension in the left-right direction is smaller) than in the floor unit 30 in the first state. In particular, the lower surface of the sliding floor 310 and the lower surface of the single removable floor piece 320 define the top surface of the prize storage section CS (part of the opening leading to the prize storage section CS is blocked). As a result, in the floor unit 30 in the second state, the opening OE formed on the left side of the sliding floor 310 is wider (its dimension in the left-right direction is larger) than in the floor unit 30 in the first state. Here, in the floor unit 30 in the second state, the area of the opening OE is larger than the area of the prize placement section AE. Also, in the floor unit 30 in the second state, the left end of the prize placement section AE is to the left of the right end of the prize outlet 17 in the left-right direction (the left end of the prize placement section AE is above the prize outlet 17, and the prize placement section AE covers the top of the prize outlet 17). As shown in FIG. 12, in the floor unit 30 in the third state, the sliding floor 310 is positioned at the right position (a position to the right of the center position), and the removable floor 320 is not attached. As a result, the upper surface of the sliding floor 310 forms the prize placement section AE. As a result, in the floor unit 30 in the third state, the prize placement section AE is narrower (its dimension in the left-right direction is smaller) compared to the floor unit 30 in the second state. In particular, the lower surface of the sliding floor 310 defines the top surface of the prize storage section CS (part of the opening leading to the prize storage section CS is blocked). As a result, in the floor unit 30 in the third state, the opening OE formed on the left side of the sliding floor 310 is wider (its dimension in the left-right direction is larger) compared to the floor unit 30 in the second state. Here, in the floor unit 30 in the third state, the area of the opening OE is larger than the area of the prize placement section AE. In addition, in the floor unit 30 in the third state, the left end of the prize placing section AE is located to the right of the right end of the prize removal opening 17 in the left-right direction (the left end of the prize placing section AE is not above the prize removal opening 17, and the prize placing section AE does not cover the top of the prize removal opening 17).

[0028] The lower housing 12 is provided with a floor sensor 330 (see FIG. 35) capable of detecting the position (left position, center position, right position) of the sliding floor 310. The floor sensor 330 outputs a detection signal according to the position of the sliding floor 310 to the control board 80. The control board 80 then sets the horizontal range of movement of the prize moving unit 210 according to the detection signal input from the floor sensor 330. Furthermore, the control board 80 determines whether or not to permit the execution of an automatic prize replenishment operation, which will be described later, according to the detection signal input from the floor sensor 330. In this case, in this embodiment, the execution of the automatic prize replenishment operation is permitted only when the sliding floor 310 is positioned in the left position (when the floor unit 30 is in the first state).

[0029] In this embodiment, by changing the configuration of the floor unit 30, it is possible to change the width (size) of the prize placement section AE. This makes it possible to adjust the width of the prize placement section AE according to the size of the prize P, making it possible to easily place the prize P on the prize placement section AE. Also, in this embodiment, by changing the configuration of the floor unit 30, it is possible to change the width (size) of the opening OE. This makes it possible to adjust the width of the opening OE according to the size of the prize P, making it possible to prevent the prize P from clogging the opening OE. In particular, in this embodiment, it is possible to diversify operations when using large prizes P. That is, when a large prize P is placed on the prize placement section AE, the floor unit 30 can be set to the first state to make the prize placement section AE wider, and even for a large prize P, it is possible to ensure space for the prize P to move in the prize placement section AE, thereby improving the enjoyment of the game. On the other hand, when a large prize P is placed above the opening OE (for example, when the prize P is supported by two rods stretched across a pair of base frames 110), the floor unit 30 can be set to the third state to make the opening OE wider, and even a large prize P can be placed above the opening OE. Furthermore, in this embodiment, when the floor unit 30 is in the first state, the prize placement section AE covers the top of the prize outlet 17, and when the floor unit 30 is in the third state, the prize placement section AE does not cover the top of the prize outlet 17. This makes it possible to optimize the width of the prize outlet 17 and prevent the prize outlet 17 from becoming too large. In this embodiment, the floor unit 30 is configured to include a sliding floor 310 that can slide in the left-right direction, and a detachable floor 320 that can be attached and detached to the side of the sliding floor 310. This makes it possible to easily expand and contract the floor unit 30.

[0030] In this embodiment, the floor unit 30 is configured so that the size of the prize placement section AE (opening OE) can be changed by attaching and detaching the detachable floor 320. However, it may also be configured so that by sliding the slide floor 310 to the right, each detachable floor 320 is stored below the slide floor 310, thereby contracting the prize placement section AE (enlarging the opening OE), and by sliding the slide floor 310 to the left, each detachable floor 320 appears and disappears from below the slide floor 310, thereby expanding the prize placement section AE (reducing the opening OE).

[0031] (Partition unit 40) Next, the configuration of the partition unit 40 will be described. Fig. 13 is a perspective view showing the partition unit 40 when the base frame 422 is positioned at the uppermost position, as viewed from the left side. Fig. 14 is a perspective view showing the partition unit 40 when the base frame 422 is positioned at the intermediate position, as viewed from the left side. Fig. 15 is a perspective view showing the partition unit 40 when the base frame 422 is positioned at the lowermost position, as viewed from the left side. Fig. 16 is a perspective view showing the partition unit 40 shown in Fig. 15 when viewed from the upper right side. Fig. 17 is a perspective view showing the partition unit 40 shown in Fig. 15 when viewed from the lower right side. Fig. 18 is a perspective view showing the partition unit 40 to which the panel member 450 has been attached. 13 to 17 show the partition unit 40 to which the rod member 440 is attached. Also, Figures 16 and 17 show the partition unit 40 with the cover member 410 removed.

[0032] As shown in Figures 13 to 17, the partition unit 40 is composed of a cover member 410, a lifting section 420 that can be raised and lowered relative to the cover member 410, and a lifting mechanism 430 that raises and lowers the lifting section 420. The cover member 410 is formed in a generally rectangular box shape with an open right side. A pair of lift rails 411 is provided on the inner surface of the cover member 410. Each lift rail 411 is provided to extend in the vertical direction. The lifting / lowering unit 420 can be raised and lowered relative to the cover member 410. The lifting / lowering unit 420 includes a lifting base 421 and a base frame 422. The lifting base 421 is a U-shaped channel member. The lifting base 421 is disposed so as to extend in the front-to-rear direction. A pair of rollers (not shown) is provided on the left side surface of the lifting base 421. The lifting base 421 is attached to the cover member 410 with each roller slidably supported by each lifting rail 411. This allows the lifting base 421 to slide (move up and down) in the vertical direction inside the cover member 410. The base frame 422 is formed in a substantially quadrangular prism shape. The base frame 422 is disposed so as to extend in the front-rear direction. A T-groove tg is provided on the upper surface of the base frame 422. The T-groove tg extends linearly along the longitudinal direction of the base frame 422 (the direction in which the base frame 422 extends). The T-groove tg is provided from one end to the other end of the base frame 422 in the longitudinal direction. The base frame 422 is attached to the lifting base 421. The base frame 422 is disposed parallel to the lifting base 421. The base frame 422 is also disposed outside the cover member 410. As a result, the base frame 422 rises and falls together with the lifting base 421 as the lifting base 421 rises and falls. The lifting mechanism 430 includes a pair of lifting rollers 431, a link mechanism 432, and a partition motor m5. Each lifting roller 431 supports the lower surface of the lifting base 421. The link mechanism 432 raises and lowers the pair of lifting rollers 431 in response to the drive of the partition motor m5. The drive of the partition motor m5 is controlled by the control board 80. Here, the lifting base 421 is placed on the outer peripheral surface of each lifting roller 421 and is not connected to each lifting roller 421 (lifting mechanism 430). As a result, when the pair of lifting rollers 421 descends, the lifting base 421 is not pulled down. Therefore, even if, for example, a prize P or an operator's hand becomes caught between the base frame 422 and the prize placement unit AE, preventing the base frame 422 (lifting unit 420) from descending, the pair of lifting rollers 421 descend away from the lifting base 421 (because they descend independently of the lifting unit 420), so the base frame 422 is not pulled down, and it is possible to prevent damage to the prize P or the operator's hand.

[0033] In this embodiment, the partition unit 40 is included in the floor unit 30. As shown in Figures 10 to 12, the partition unit 40 is attached to the sliding floor 310. As a result, the partition unit 40 slides together with the sliding floor 310 as the sliding floor 310 slides in the left-right direction. Specifically, the cover member 410 is attached to the underside of the sliding floor 310. The base frame 422 is disposed on the left side of the sliding floor 310. In other words, the base frame 422 is disposed at the boundary between the prize placement section AE and the opening OE. In particular, various members (such as the rod member 440, panel member 450, and frame member 460 described below) can be attached and detached to the T-slot tg of the base frame 422. The members (such as the rod member 440, panel member 450, and frame member 460) attached to the T-slot tg of the base frame 422 can be used as partition members that separate the opening OE and the prize placement section AE. For example, as shown in FIGS. 13 to 15, one or more rod members 440 can be attached as partition members to the T-slot tg of the base frame 422. Each rod member 440 is a bar-shaped member. Each rod member 440 includes a rod portion 441 and a joint portion 442 attached to the lower end of the rod portion 441. The rod portion 441 is formed in a cylindrical shape. The joint portion 442 includes a fixing nut portion 422a and a T-slot nut portion (T-slot nut portion, not shown). Each rod member 440 can be attached to the base frame 422 by inserting the T-slot nut portion into the T-slot tg and rotating the fixing nut 442a clockwise to sandwich the top surface of the base frame 422 between the upper surface of the T-slot nut portion and the lower surface of the fixing nut 442a. In this case, one or more rod members 440 can be attached to the base frame 422. In particular, the mounting position of each rod member 440 on the base frame 422 can be adjusted (moved) steplessly along the front-to-rear direction (along the T-slot tg). As a result, when a plurality of rod members 440 are mounted on the base frame 422, by setting the interval between adjacent rod members 440 wider than the width of the claw members 241a, it becomes possible for the arm 241 that has entered the opening OE side of the rod member 440 to pass from the opening OE side to the prize placement part AE side, and it becomes possible to prevent a situation in which the gripping of the prize P by the arm 241 is obstructed.

[0034] The lifting base 421 is provided with a lifting sensor 421a (see FIG. 35) for detecting the position (height) of the base frame 422 (lifting base 421). The lifting sensor 421a outputs a detection signal to the control board 80 as the base frame 422 (lifting base 421) moves up and down. The control board 80 is then able to detect the position (height) of the base frame 422 (lifting base 421) based on the detection signal input from the lifting sensor 421a. In this embodiment, the position (height) of the base frame 422 (the partition member attached to the base frame 422) is changed depending on the number of times the prize acquisition game is played. Specifically, the position (height) of the base frame 422 (the partition member attached to the base frame 422) is changed depending on the number of consecutive plays. The "number of consecutive plays" refers to the number of consecutive plays. "Continuous play" refers to the play of the next prize game when the next prize game is executed without transitioning to the attract state after the end of the previous prize game. In other words, a continuation period of a predetermined time (e.g., 30 seconds) is set at the end of each prize game. If the conditions for starting the prize game are met during the continuation period (in this embodiment, when the insertion of a coin into the coin slot 14 is detected), the continuous play continues. On the other hand, if the continuation period ends without the conditions for starting the prize game being met, the continuous play is interrupted. Note that the continuous play may be interrupted when the winning of a prize P is detected. In this embodiment, the position (height) of the base frame 422 (partition member) is lowered as the number of consecutive plays increases. The control board 80 detects the position (height) of the base frame 422 (partition member) based on the detection signal input from the elevation sensor 421a, and controls the drive of the partition motor m5 so that the base frame 422 (partition member) is positioned at a predetermined position (predetermined height). For example, during the attract state, the base frame 422 (partition member) is disposed at the upper limit position (initial position, see FIG. 13). Then, during continuous play, when the number of continuous plays reaches a first predetermined number (e.g., 10 times), the base frame 422 (partition member) is lowered to the intermediate position (see FIG. 14). Furthermore, during continuous play, when the number of continuous plays reaches a second predetermined number (e.g., 20 times), the base frame 422 (partition member) is lowered to the lower limit position (see FIG. 15). Furthermore, when continuous play is interrupted, the base frame 422 (partition member) is returned to the upper limit position (initial position, see FIG. 13). As a result, the height of the rod member 440 (partition member) can be lowered as the number of continuous plays increases, thereby improving the enjoyment of the game. In this embodiment, the previous number of consecutive plays is displayed on the touch panel display 15. As a result, when the consecutive plays are interrupted due to a malfunction and the base frame 422 is returned to the upper limit position (initial position), the operator can return the position of the base frame 422 (partition member) to the position before the consecutive plays were interrupted, based on the displayed number of consecutive plays.

[0035] 18, a panel member 450 can be attached as a partition member to the T-groove tg of the base frame 422. The panel member 450 is a flat plate-shaped member made of a transparent material such as glass or acrylic. This makes it possible to lower the height of the panel member 450 (partition member) as the number of consecutive plays increases, thereby improving the playability of the game. Furthermore, a frame member 460 (see FIG. 20) can be attached as a partition member to the T-groove tg of the base frame 422. This makes it possible to lower the height of the frame member 460 (partition member) as the number of consecutive plays increases, thereby improving the playability of the game.

[0036] In this embodiment, the partition members can be attached and detached to the base frame 422, which can be raised and lowered. This makes it possible to change and improve the playability of the game by deciding whether or not to attach a partition member to the base frame 422, or by changing the type of partition member attached to the base frame 422. Furthermore, in this embodiment, the attachment position of the partition member can be adjusted along the base frame 422. This makes it possible to change the gameplay according to the attachment position of the partition member on the base frame 422, thereby further improving the gameplay. Furthermore, in this embodiment, it is possible to attach multiple partition members to the base frame 422. This makes it possible to change the gameplay according to the number of partition members attached to the base frame 422, thereby further improving the gameplay. In addition, in this embodiment, it is possible to use a rod member 440, which is a bar-shaped member, as the partition member. This prevents the arm 241 (claw portion 241a) from interfering with the partition member, thereby preventing a situation in which the playability of the game is reduced. In this embodiment, the base frame 422 descends in accordance with the number of consecutive plays, which makes it possible to change the gameplay in accordance with the number of consecutive plays, thereby further improving the gameplay. Furthermore, in this embodiment, the base frame 422 returns to the upper limit position (initial position) when continuous play ends. This makes it possible to change the gameplay when continuous play ends, further improving the gameplay.

[0037] Here, the above explanation has described an example in which the members (rod member 440, panel member 450, frame member 460, etc.) attached to the T-groove tg of the base frame 422 are configured as partition members that separate the opening OE and the prize placement section AE. However, in this embodiment, the members (rod member 440, panel member 450, frame member 460, frame member 480, etc.) attached to the T-groove tg of the base frame 422 may be configured as part of the mechanism for placing prizes P in the game area GE (particularly, placement members for placing prizes P). In other words, the base frame 422 may be configured as a support member (support mechanism) that supports the placement mechanism. Fig. 19 is a diagram showing an example of operation in which rod member 440 attached to base frame 422 is used as a positioning member. Fig. 20 is a diagram showing a first example of operation in which frame member 460 attached to base frame 422 is used as a positioning member. Fig. 21 is a diagram showing a second example of operation in which frame member 460 attached to base frame 422 is used as a positioning member.

[0038] For example, as shown in FIG. 19 , in this embodiment, one or more rod members 440 can be attached as placement members in the T-slot tg of the base frame 422. Here, the rod 470 is a bar-shaped member. The attachment position of each rod member 440 on the base frame 422 can be continuously adjusted (moved) along the front-rear direction (along the T-slot tg). In this example, a pair of rods 470 are attached at a predetermined interval to the base frame 110 of the right-side lifting frame unit 100. In this case, the right end of each rod 470 is attached to the T-slot tg of the base frame 110. In addition, a pair of rod members 440 are attached at a predetermined interval to the base frame 422. The left end of each rod 470 is supported by the tip surface of each rod member 440. As a result, the pair of rods 470 and the pair of rod members 440 constitute a placement member (placement mechanism) for placing the prize P, and the placement member is supported by the base frame 422. Then, by supporting the prize P with the pair of rods 470, it becomes possible to place the prize P above the prize placement section AE. As described above, the position (height) of the base frame 422 (the arrangement component attached to the base frame 422) is configured to change depending on the number of consecutive plays. Specifically, the position (height) of the base frame 422 (the arrangement component) is configured to decrease as the number of consecutive plays increases. For example, during the attract state, the base frame 422 (the arrangement component) is positioned at the upper limit position (initial position). Then, during the continuous play, when the number of consecutive plays reaches a first predetermined number (e.g., 10 times), the base frame 422 (the arrangement component) is lowered to the intermediate position. Furthermore, during the continuous play, when the number of consecutive plays reaches a second predetermined number (e.g., 20 times), the base frame 422 (the arrangement component) is lowered to the lower limit position. Furthermore, when the continuous play is interrupted, the base frame 422 (the arrangement component) is returned to the upper limit position (initial position). As a result, the height of the rod member 440 (positioning member) decreases as the number of consecutive plays increases, making it possible to tilt the pair of rods 470 toward the opening OE, thereby improving the playability of the game. Alternatively, a pair of rods 470 may be attached at a predetermined interval to the base frame 110 of the left-side lifting frame unit 100. That is, the left end of each rod 470 may be attached to the T-groove tg of the base frame 110 of the left-side lifting frame unit 100, and the right end of each rod 470 may be supported by the tip surface of each rod member 440. This allows the prize P to be supported by the pair of rods 470, making it possible to place the prize P above the opening OE. As the number of consecutive plays increases, the height of the rod member 440 (placement member) decreases, making it possible to tilt the pair of rods 470 toward the prize placement unit AE, thereby improving the playability of the game.

[0039] Alternatively, as shown in FIG. 20 , in this embodiment, one or more frame members 460 can be attached as placement members in the T-slot tg of the base frame 422. Here, the frame member 460 is an endless (annular) member having a substantially rectangular shape. The attachment position of each frame member 460 on the base frame 422 can be continuously adjusted (moved) in the front-to-rear direction (along the T-slot tg). In this example, a pair of rods 470 are attached at a predetermined interval to the base frame 110 of the right-side lifting frame unit 100. In this case, the right ends of each rod 470 are attached to the T-slot tg of the base frame 110. Furthermore, two frame members 460 are attached at a predetermined interval to the base frame 422. The left ends of each rod 470 are supported by the upper surfaces of the frame members 460. As a result, the pair of rods 470 and the two frame members 460 constitute a placement member (placement mechanism) for placing the prize P, and the placement member is supported by the base frame 422. Then, by supporting the prize P with the pair of rods 470, it becomes possible to place the prize P above the prize placement section AE. As described above, the position (height) of the base frame 422 (the arrangement member attached to the base frame 422) is configured to change depending on the number of consecutive plays. Specifically, the position (height) of the base frame 422 (the arrangement member) is configured to become lower as the number of consecutive plays increases. This allows the pair of rods 470 to be tilted toward the opening OE as the height of the frame member 460 (the arrangement member) decreases as the number of consecutive plays increases, thereby improving the playability of the game. Alternatively, a pair of rods 470 may be attached at a predetermined interval to the base frame 110 of the left-side lifting frame unit 100. That is, the left end of each rod 470 may be attached to the T-groove tg of the base frame 110 of the left-side lifting frame unit 100, and the right end of each rod 470 may be supported by the upper surface of each frame member 460. This allows the prize P to be supported by the pair of rods 470, making it possible to place the prize P above the opening OE. As the number of consecutive plays increases, the height of the frame member 460 (placement member) decreases, making it possible to tilt the pair of rods 470 toward the prize placement unit AE, thereby improving the playability of the game.

[0040] Alternatively, as shown in FIG. 21 , in this embodiment, one or more frame members 480 can be attached as the arrangement member. Here, the frame member 480 is formed in a substantially rectangular prism shape. T-slots (not shown) are provided on the side of the frame member 480. Each T-slot extends linearly along the longitudinal direction of the frame member 480 (the direction in which the frame member 480 extends). Each T-slot is provided from one end to the other end of the frame member 480 in the longitudinal direction. The attachment position of each frame member 480 on the base frame 422 can be continuously adjusted (moved) along the front-rear direction (along the T-slot tg). In this example, two frame members 480 are attached to the base frame 422 at a predetermined interval. Then, a frame member 460 is attached to the left side of the two frame members 480. In this case, the frame member 460 is attached to the T-slot of each frame member 480. As a result, the frame member 460 and the two frame members 480 constitute a placement member (placement mechanism) for placing the prize P, and the placement member is supported by the base frame 422. Then, by placing the prize P on the upper surface of the frame member 480, it becomes possible to place the prize P above the opening OE. As described above, the position (height) of the base frame 422 (the arrangement member attached to the base frame 422) is configured to change depending on the number of consecutive plays. Specifically, the position (height) of the base frame 422 (the arrangement member) is configured to be lower as the number of consecutive plays increases. This makes it possible to lower the height of the frame member 460 as the height of the frame member 480 (the arrangement member) decreases as the number of consecutive plays increases, thereby improving the playability of the game.

[0041] In the above embodiment, the position (height) of the base frame 422 is lowered as the number of consecutive plays increases. However, the position (height) of the base frame 422 may be higher as the number of consecutive plays increases. Furthermore, in the above embodiment, a configuration may be adopted in which a placement member for placing prizes in the game area can be attached, and a plurality of base frames whose elevation is controlled by the control board 80. That is, each lifting frame unit 100 (base frame 110) may also be configured such that the position (height) of the base frame 110 (the placement member attached to the base frame 110) can be controlled by the control board 80, similar to the partition unit 40 (base frame 422). For example, each lifting frame unit 100 (base frame 110) may also be configured such that the position (height) of the base frame 110 (the placement member attached to the base frame 110) changes depending on the number of times the prize acquisition game is played, similar to the partition unit 40 (base frame 422). Specifically, the position (height) of the base frame 110 may be lowered as the number of consecutive plays increases. Alternatively, the position (height) of the base frame 110 may be higher as the number of consecutive plays increases. In this embodiment, the base frame 422, to which placement members for placing prizes P in the game area GE can be attached, can be automatically raised and lowered. This makes it possible to change the way the prizes P are placed, thereby improving the enjoyment of the game. In this embodiment, the base frame 422 moves up and down depending on the number of consecutive plays, which makes it possible to change the way prizes P are arranged depending on the number of consecutive plays, further improving the enjoyment of the game. In addition, in this embodiment, a plurality of base frames 422, 110 that can be controlled to rise and fall are provided, which allows the arrangement of prizes P to be varied in a variety of ways. In addition, in this embodiment, the prize P can be placed above the prize placement section AE by the placement member, which allows for more diverse placement of the prize P. In addition, in this embodiment, the prize P can be placed above the opening OE by the placement member, which allows the prize P to be placed in a variety of ways. Furthermore, in this embodiment, the attachment position of the placement member can be adjusted along the base frame 422. This makes it possible to diversify the placement of the prizes P depending on the attachment position of the placement member on the base frame 422.

[0042] (50 prize refill units) Next, the configuration of the prize replenishing unit 50 will be described. Fig. 22 is a perspective view showing the prize refill unit 50. Fig. 23 is a view showing the prize refill unit 500 shown in Fig. 22 with the side cover removed. Fig. 24 is a perspective view showing the prize refill unit 50 in an initial state. Fig. 25 is a perspective view showing the prize refill unit 50 in a first state. Fig. 26 is a perspective view showing the prize refill unit 50 in a second state. As shown in FIGS. 1, 22 and 23, the prize replenishing unit 50 includes a guide unit 500, a prize placing section 510, and a prize supporting section 520. As shown in FIG. The guide unit 500 is configured to include a first rail 501, a first slide base 502, a first prize replenishment motor m6, a second rail 503, a second slide base 504, and a second prize replenishment motor m7. The first rail 501 extends linearly in the front-to-rear direction. The first slide base 502 is attached to the first rail 501 and is slidable along the first rail 501. The first slide base 502 slides along the first rail 501 in response to the driving of the first prize replenishing motor m6. The driving of the first prize replenishing motor m6 is controlled by the control board 80. The second rail 503 extends linearly in the front-to-rear direction. The second slide base 504 is attached to the second rail 503 and is slidable along the second rail 503. The second slide base 504 slides along the second rail 503 in response to the drive of the second prize replenishing motor m7. The drive of the second prize replenishing motor m7 is controlled by the control board 80.

[0043] The prize placing section 510 is configured to include a placing plate 511 on which a prize P can be placed, and a connecting arm 512 attached to the placing plate 511. The placing plate 511 is formed in the shape of a substantially rectangular flat plate in a plan view. The prize placing section 510 is attached to the guide unit 500. Specifically, the placing plate 511 is attached to the second slide base 504 via the connecting arm 512. This allows the prize placing section 510 to slide along the second rail 503 by being driven by the second prize replenishment motor m7. At this time, the placing plate 511 slides with respect to the prize placing section AE at a predetermined interval (for example, 1 cm). The prize support section 520 is configured to include a support plate 521 capable of supporting the back surface of the prize P placed on the placement plate 511, and a connecting arm 522 attached to the support plate 521. The support plate 521 is formed in the shape of a substantially rectangular flat plate when viewed from the front. The prize support section 520 is attached to the guide unit 500. Specifically, the support plate 521 is attached to the first slide base 502 via the connecting arm 522. This allows the prize support section 520 to slide along the first rail 501 by being driven by the first prize refill motor m6. Here, the prize placing section 510 and the prize supporting section 520 are slidable independently (individually) from each other. The prize placing section 510 can be slid (displaced / moved) between an initial position (see FIG. 24) and a prize placement position (see FIG. 25). The initial position is set in the display area DE. On the other hand, the prize placement position is set in the game area GE (prize placing section AE). Here, the guide unit 500 is provided with a first initial position detection sensor 513 (see FIG. 35) that detects that the prize placing section 510 has been placed in the initial position, and a first prize placement position detection sensor 514 (see FIG. 35) that detects that the prize placing section 510 has been placed in the prize placement position. When the prize placing section 510 is placed in the initial position, the first initial position detection sensor 513 outputs a detection signal to the control board 80. This enables the control board 80 to determine whether or not the prize placing section 510 is placed in the initial position, depending on whether or not a detection signal is input from the first initial position detection sensor 513. The first prize placement position detection sensor 514 outputs a detection signal to the control board 80 in response to the prize placement section 510 being placed at the prize placement position. This enables the control board 80 to determine whether or not the prize placement section 510 is placed at the prize placement position in response to whether or not a detection signal is input from the first prize placement position detection sensor 514.

[0044] The prize support section 520 can slide (displace / move) between an initial position (see FIG. 24) and a prize placement position (see FIG. 25). The initial position is set in the display area DE. On the other hand, the prize placement position is set in the game area GE (prize placement section AE). Here, the guide unit 500 is provided with a second initial position detection sensor 523 (see FIG. 35) that detects that the prize support section 520 has been placed in the initial position, and a second prize placement position detection sensor 524 (see FIG. 35) that detects that the prize support section 520 has been placed in the prize placement position. When the prize support section 520 is placed in the initial position, the second initial position detection sensor 523 outputs a detection signal to the control board 80. This enables the control board 80 to determine whether the prize support section 520 is placed in the initial position or not, depending on whether a detection signal is input from the second initial position detection sensor 523 or not. The second prize placement position detection sensor 524 outputs a detection signal to the control board 80 in response to the prize support section 520 being placed at the prize placement position. This enables the control board 80 to determine whether or not the prize support section 520 is placed at the prize placement position in response to whether or not a detection signal is input from the second prize placement position detection sensor 524.

[0045] As shown in FIG. 23 , in this embodiment, the first prize placement position detection sensor 514 and the second prize placement position detection sensor 524 are integrated into a single unit to form a sensor unit 530. The position (placement) of the sensor unit 530 in the guide unit 500 can be changed (moved) along the guide unit 500 (first rail 501 and second rail 502). By changing the position of the sensor unit 530, the prize placement positions in the prize placement section 510 and the prize placement positions in the prize support section 520 can be changed in the front-to-rear direction. At this time, the sensor unit 530 is fixed to the guide unit 500 by a urea screw 540. This allows the position of the sensor unit 530 to be changed without the need for tools.

[0046] Next, a method for replenishing prizes P using the prize replenishing unit 50 will be described. In order to execute the automatic prize replenishment operation, it is necessary to place the prizes P to be replenished in advance in the prize replenishment unit 50 in its initial state. As shown in FIG. 24, in the prize replenishment unit 50 in its initial state, the prize placing section 510 is placed in its initial position, and the prize support section 520 is also placed in its initial position. Here, in the prize replenishment unit 50 in its initial state, the prize placing section 510 (placing plate 511) and the prize support section 520 (support plate 521) are both placed in the display area DE. As a result, the prizes P to be replenished placed in the prize replenishment unit 50 in its initial state are also placed in the display area DE. To place a prize P for refilling in the prize refill unit 50 in its initial state, the prize P is placed on the upper surface of the placing plate 511. At this time, in the prize refill unit 50 in its initial state, the support plate 521 is placed on the rear side of the placing plate 511. This makes it possible for the support plate 521 to support the rear side of the prize P placed on the upper surface of the placing plate 511, making it possible to prevent the prize P from tipping over, etc. Then, the control board 80 executes the automatic prize replenishment operation in response to detection of the player's play resulting in the acquisition of a prize P. At this time, as described above, in this embodiment, when the sliding floor 310 is positioned at the left position, the execution of the automatic prize replenishment operation is permitted, and when the sliding floor 310 is not positioned at the left position, the execution of the automatic prize replenishment operation is prohibited. When the automatic prize replenishment operation is initiated, first, the prize replenishing unit 50 transitions from the initial state to the first state. That is, as shown in FIG. 25 , the prize placing section 510 is moved from the initial position to the prize placement position, and the prize support section 520 is moved from the initial position to the prize placement position. At this time, the prize placing section 510 (placing plate 511) and the prize support section 520 (support plate 521) are moved from the initial position to the prize placement position while maintaining the positional relationship in the initial state. In the prize replenishing unit 50 in the first state, the prize placing section 510 is positioned at the prize placement position, and the prize support section 520 is positioned at the prize placement position. Here, in the prize replenishing unit 50 in the first state, the prize placing section 510 (placing plate 511) and the prize support section 520 (support plate 521) are both positioned in the game area GE (above the prize placing section AE). As a result, the refill prizes P placed in the prize refill unit 50 in the first state are also placed in the game area GE (above the prize placement section AE). Next, the prize refill unit 50 transitions from the first state to the second state. That is, as shown in FIG. 26, with the prize support section 520 positioned at the prize placement position, the prize placement section 510 is moved from the prize placement position to the initial position. As a result, with the back of the prize P supported by the support plate 521, the placement plate 511 is removed from below the prize P, and the prize P placed on the top surface of the placement plate 511 falls onto the prize placement section AE (prize placement position) and is placed on the prize placement section AE. At this time, the support plate 521 supports the back side of the prize P, making it possible to prevent the prize P from tipping over, etc. In the prize refill unit 50 in the second state, the prize placement section 510 is positioned at the initial position, and the prize support section 520 is positioned at the prize placement position. Next, the prize refill unit 50 returns from the second state to the initial state. That is, with the prize placement section 510 placed in the initial position, the prize support section 520 is moved from the prize placement position to the initial position. This causes the prize refill unit 50 to return to the initial state, and the automatic prize refill operation ends. In this embodiment, the prize placing section 510 on which the prize P can be placed and the prize support section 520 which can support the back side of the prize placed on the prize placing section 510 can be moved independently in the front-to-rear direction. This makes it possible to replenish the prize P at the intended position (i.e., the prize placing position). Furthermore, in this embodiment, after the prize placing section 510 and the prize support section 520 have been moved to the prize placing position, the prize placing section 510 can be moved rearward without moving the prize support section 520, thereby making it possible to place the prize P placed on the prize placing section 510 at the prize placing position. This makes it possible to place the prize P placed on the prize placing section 510 at the prize placing position without it tipping over. Furthermore, in this embodiment, the prize placing section 510 is moved with a predetermined gap between it and the prize placing section AE. This allows the prize placing section 51 to be moved without being affected by any steps in the prize placing section AE. Furthermore, even if the prize placing section AE is covered with plastic balls (resin balls), the prize placing section 51 can be moved without being affected by the plastic balls. Furthermore, in this embodiment, a first prize placement position detection sensor 514 is provided that can detect when the prize placement section 510 has reached the prize placement position. The prize placement position can be changed by changing the position of the first prize placement position detection sensor 514. This makes it possible to easily change the prize placement position.

[0047] (Open / close door unit 60) Next, the configuration of the opening and closing door unit 60 will be described. Fig. 27 is a perspective view showing the opening / closing door unit 60 in the door closed state, and Fig. 28 is a perspective view showing the opening / closing door unit 60 in the door open state. 27 and 28, the left side surface of the lower housing 12 is not shown. As shown in FIGS. 27 and 28, the opening / closing door unit 60 includes an opening / closing door 610, a shutter plate 620, and a link mechanism 630.

[0048] The opening / closing door 610 is made of a transparent material such as acrylic and is formed in the shape of a substantially rectangular flat plate. The opening / closing door 610 is configured to have substantially the same size as the prize outlet 17. The opening / closing door 610 is capable of opening and closing the prize outlet 17. Specifically, the opening / closing door 610 is provided with an opening / closing shaft (not shown). The opening / closing shaft is attached along the upper edge of the opening / closing door 610. Each end of the opening / closing shaft is rotatably supported by the lower housing 12. This allows the opening / closing door 610 to rotate around the opening / closing shaft. In this case, the lower end of the opening / closing door 610 can be rotated toward the back side (rear side) of the prize outlet 17. The opening / closing door 610 can be rotated (opened and closed) between a closed position (see FIG. 27) and a maximum open position (see FIG. 28). When the opening / closing door 610 is placed in the closed position, the opening / closing door 610 is positioned approximately vertically, and the prize outlet 17 is closed in its entirety when viewed from the front. On the other hand, when the opening / closing door 610 is placed in the maximum open position, the opening / closing door 610 is positioned approximately horizontally, and the prize outlet 17 is open in its entirety when viewed from the front.

[0049] The shutter plate 620 is made of a material such as acrylic and is formed in the shape of a substantially rectangular flat plate. The shutter plate 620 is configured to have substantially the same width as the opening and closing door 610. A pair of rails 621 is provided on the lower housing 12. Each rail 621 extends linearly in the front-to-rear direction. The shutter plate 620 is slidable along the pair of rails 621 while being disposed substantially horizontally. The shutter plate 620 is slidable (retractable) between a retracted position (see FIG. 27) and a maximum protrusion position (see FIG. 28). When the shutter plate 620 is positioned in the retracted position, substantially the entire shutter plate 620 is retracted below the display area DE in a plan view, leaving the opening (opening OE in this embodiment) leading from the prize container CS to the game area GE open. On the other hand, when the shutter plate 620 is positioned in the maximum protrusion position, substantially the entire shutter plate 620 protrudes (appears) toward the opening OE in a plan view, closing a portion of the opening (opening OE in this embodiment) leading from the prize container CS to the game area GE.

[0050] The link mechanism 630 slides (appears and retracts) the shutter plate 620 in accordance with the rotation (opening and closing) of the opening and closing door 610. Specifically, the shutter plate 620 is connected to the opening and closing door 610 via the link mechanism 630. As a result, in the opening / closing door unit 60, when the opening / closing door 610 is in the closed position, the shutter plate 620 is in the retracted position (hereinafter referred to as the "door closed state"). As shown in Fig. 27, when the opening / closing door unit 60 is in the door closed state, the entire opening (the opening OE in this embodiment) leading from the prize container CS to the game area GE is in an open state. In the opening / closing door unit 60, as the opening / closing door 610 is gradually opened (as the opening / closing door 610 is gradually rotated from the closed position toward the open limit position), the shutter plate 620 gradually protrudes (as the shutter plate 620 is gradually slid from the retracted position toward the protruding limit position). In the opening / closing door unit 60, when the opening / closing door 610 is positioned at the maximum open position, the shutter plate 620 is positioned at the maximum protrusion position (hereinafter referred to as the "door open state"). As shown in Fig. 28, when the opening / closing door unit 60 is in the door open state, the opening / closing door 610 and the shutter plate 620 are both positioned horizontally and lined up in the front-to-back direction. As a result, when the opening / closing door unit 60 is in the door open state, the opening (the opening OE in this embodiment) leading from the prize container CS to the game area GE is substantially entirely closed by the opening / closing door 610 and the shutter plate 620.

[0051] As a result, when the opening / closing door 610 is placed in the closed position (when the opening / closing door unit 60 is in the door closed state), almost the entire opening (in this embodiment, the opening OE) leading from the prize container CS to the game area GE is opened, and the prize P that has fallen into the opening OE is contained (guided) into the prize container CS. Thereafter, the player can open the opening / closing door 610 to remove the prize P contained in the prize container CS. Here, when using a large prize P, it is necessary to enlarge the opening OE and the prize outlet 17. However, if the opening OE and the prize outlet 17 are enlarged, there is a risk of fraudulent activity, such as reaching in through the prize outlet 17 to obtain a prize P placed in the game area GE. Therefore, in this embodiment, when the opening / closing door 610 is opened, the opening / closing door 610 closes at least a portion of the opening leading from the prize storage unit CS to the game area GE (in this embodiment, the opening OE), and the shutter plate 620 closes at least a portion of the opening leading from the prize storage unit CS to the game area GE (in this embodiment, the opening OE). This prevents the above-mentioned fraudulent activity. That is, in this embodiment, as the opening / closing door 610 is opened, the shutter plate 620 is pushed out from below the display area DE toward the opening OE. When the opening / closing door 610 is positioned in the maximum open position (when the opening / closing door unit 60 is in the door open state), the opening (in this embodiment, the opening OE) leading from the prize storage unit CS to the game area GE is almost entirely closed by the opening / closing door 610 and the shutter plate 620, making it difficult to enter the game area GE from the prize storage unit CS (making it difficult for hands or prizes P to pass through the opening OE). This makes it possible to prevent the above-mentioned fraudulent acts. In this embodiment, when the opening / closing door 610 is opened, the opening / closing door 610 closes at least a portion of the opening leading from the prize storage unit CS to the game area GE (in this embodiment, the opening OE), and the shutter plate 620 closes at least a portion of the opening leading from the prize storage unit CS to the game area GE (in this embodiment, the opening OE). However, when the opening / closing door 610 is opened, the shutter plate 620 may close substantially the entire opening leading from the prize storage unit CS to the game area GE (in this embodiment, the opening OE). In this embodiment, as the opening and closing door 610 opens and closes, at least a portion of the opening (in this embodiment, the opening OE) leading from the prize storage section CS to the game area GE is opened and closed by the shutter plate 620. This makes it possible to prevent fraudulent acts such as reaching in through the prize outlet 17 to take a prize P placed in the game area GE. In particular, in this embodiment, when the opening and closing door 610 is opened, the shutter plate 620 closes at least a part of the opening (the opening OE in this embodiment) that leads from the prize container CS to the game area GE. This makes it possible to prevent the above-mentioned fraudulent acts. Furthermore, in this embodiment, when the opening and closing door 610 is closed, the shutter plate 620 is positioned so as not to prevent the prize P from passing through the opening (opening OE in this embodiment) that leads from the prize storage section CS to the game area GE. This makes it possible to prevent the shutter plate 620 from interfering with the acquisition of the prize P. Furthermore, in this embodiment, when the opening / closing door 610 is opened, the opening leading from the prize container CS to the game area GE (the opening OE in this embodiment) is closed by the opening / closing door 610 and the shutter plate 620. This makes it possible to close the opening leading from the prize container CS to the game area GE (the opening OE in this embodiment) with a simple configuration.

[0052] (Display Unit 70) Next, the configuration of the display unit 70 will be described. Fig. 29 is a perspective view showing display unit 70. Fig. 30 is a perspective view showing the front side of back plate unit 700. Fig. 31 is a perspective view showing the rear side of back plate unit 700. Fig. 32 is a perspective view showing fixing unit 710. Fig. 33 is a cross-sectional view of support blade 711. Fig. 34 is a perspective view showing rod member 730. FIG. 29 shows a state in which rear panel unit 700 is pulled out toward the front side. As shown in FIG. 29, the display unit 70 includes a back panel unit 700 and one or more fixing units 710 that can be attached to or detached from the back panel unit 700. As shown in FIGS. 30 and 31, the back plate unit 700 includes a back plate 701, a pair of hanging metal fittings 702, and a locking mechanism 703. The rear plate 701 is formed in a substantially rectangular flat plate shape. A plurality of engagement portions 701a are provided at predetermined intervals along the vertical direction on each of the left and right ends of the rear plate 701. One of the hanging metal fittings 702 is attached to the upper left corner of rear plate 701. The other hanging metal fitting 702 is attached to the upper right corner of rear plate 701. Each hanging metal fitting 702 is provided so as to protrude from rear plate 701 toward the front side. Each hanging metal fitting 702 is provided with a roller 702a on its outer side. The locking mechanism 703 includes a pair of operating units 704, a pair of locking rods 705, and a link mechanism 706. Each operating unit 704 includes an operating shaft 704a extending in the front-rear direction and a lever 704b attached to the front end of the operating shaft 704a. Each operating unit 704 can be switched between a locked state and an unlocked state by rotating the lever 704b around the operating shaft 704b. Each locking rod 705 is a rod-shaped member extending in the up-down direction. Each locking rod 705 can be switched between a locked position where its upper end protrudes upward from the top end of the back panel 701 and an unlocked position where its upper end does not protrude upward from the top end of the back panel 701. The link mechanism 706 is attached to the back side of the back panel 701. The pair of operating units 704 and the pair of locking bars 705 are connected to each other by a link mechanism 706. As a result, the pair of operating units 704 and the pair of locking bars 705 are interlocked with each other by the link mechanism 706. Specifically, when one operating unit 704 is placed in the locked state, the other operating unit 704 is also placed in the locked state, and each locking bar 705 is placed in the locked position. On the other hand, when one operating unit 704 is placed in the released state, the other operating unit 704 is also placed in the released state, and each locking bar 705 is placed in the released position.

[0053] A pair of suspension rails 707 are provided on the inner wall surface of lower housing 12. Note that only one of suspension rails 707 is shown in FIG. 29 . One suspension rail 707 is provided on the right side surface of lower housing 12 so as to extend along the front-to-rear direction. The other suspension rail 707 is provided on the left side surface of lower housing 12 so as to extend along the front-to-rear direction. Back plate unit 700 is attached to lower housing 12 by having rollers 702a of suspension fittings 702 on one side (right side) slidably supported by suspension rail 707 on one side (right side) and rollers 702a of suspension fittings 702 on the other side (left side) slidably supported by suspension rail 707 on the other side (left side). This allows back plate unit 700 to slide along the front-to-rear direction inside lower housing 12, as shown in FIG. 29 . The back panel unit 700 is capable of sliding (moving) between an initial position (see FIG. 1) and a front limit position (not shown). Each hanging rail 707 is provided with a plurality of locking holes (not shown) at predetermined intervals along the front-to-rear direction. Locking mechanism 703 is capable of locking (preventing) movement of back panel unit 700 in the front-to-rear direction relative to lower housing 12 by fitting the upper end of locking rod 705, which is positioned at the locked position, into the locking hole. In this embodiment, each hanging rail 707 is provided with a plurality of locking holes at 5 cm intervals. This makes it possible to lock the position of back panel unit 700 in lower housing 12 (pair of hanging rails 707) every 5 cm along the front-to-rear direction. Back plate unit 700 arranged in the initial position can be maintained in the initial position by fitting the upper end of each locking rod 705 into the locking hole arranged furthest to the rear among multiple locking holes provided in each hanging rail 707. Then, with back plate unit 700 arranged in the initial position, by shifting lever portion 704b from the locked state to the unlocked state, back plate unit 700 is unlocked by locking mechanism 703 and can be slid toward the front. Then, after sliding back plate unit 700 to a desired position, by shifting lever portion 704b from the unlocked state to the locked state and fitting the upper end of each locking rod 705 into any of the multiple locking holes provided in each hanging rail 707, the position of back plate unit 700 can be locked.

[0054] The lower housing 12 is provided with a display sensor 708 (see FIG. 35) that can detect that the back panel unit 700 is placed in the initial position. The display sensor 708 outputs a detection signal to the control board 80 when the back panel unit 700 is placed in the initial position. The control board 80 then determines whether the back panel unit 700 is placed in the initial position depending on whether a detection signal is input from the display sensor 708. In this case, in this embodiment, execution of the prize acquisition game is permitted only when the back panel unit 700 is placed in the initial position.

[0055] As shown in FIG. 32, each fixing unit 710 includes a pair of support blades 720 and a rod member 730 supported by the pair of support blades 720 . As shown in FIG. 33, each support blade 720 includes an upper support member 740 , a lower support member 750 , and an engaging fitting 760 . The upper support member 740 is a rod-shaped member extending linearly along the front-rear direction. A slide groove 741 is provided on the lower surface of the upper support member 740. The slide groove 741 extends linearly along the longitudinal direction (front-rear direction) of the upper support member 740. The slide groove 741 is provided from one longitudinal end of the upper support member 740 to the other longitudinal end. A serration portion 742 is provided on the top surface of the slide groove 741. The serration portion 742 is formed in a downward sawtooth shape with locking ridges 743 and grooves (engaged portions) 744 alternately arranged along the longitudinal direction (front-rear direction). In other words, the serration portion 742 has a plurality of locking ridges 743 arranged at predetermined intervals along the longitudinal direction (front-rear direction), and a plurality of grooves 744 arranged at predetermined intervals. Each locking ridge 743 extends in a direction perpendicular to the longitudinal direction (left-right direction). Of the two surfaces that make up each locking ridge 743, the surface on the front side is an inclined surface that is higher on the front side and lower on the rear side, and the surface on the rear side is a vertical surface. The lower support member 750 is a rod-shaped member extending linearly along the front-rear direction. A slide groove 751 is provided on the upper surface of the lower support member 750. The slide groove 751 extends linearly along the longitudinal direction (front-rear direction) of the lower support member 750. The slide groove 751 is provided from one longitudinal end of the lower support member 750 to the other longitudinal end. A serration portion 752 is provided on the bottom surface of the slide groove 751. The serration portion 752 has locking ridges 753 and grooves (engaged portions) 754 alternately arranged along the longitudinal direction (front-rear direction), forming an upwardly facing sawtooth shape. In other words, the serration portion 752 has a plurality of locking ridges 753 arranged at predetermined intervals along the longitudinal direction (front-rear direction), and a plurality of grooves 754 also arranged at predetermined intervals along the longitudinal direction (front-rear direction). Each locking ridge 753 extends in a direction perpendicular to the longitudinal direction (left-right direction). Of the two surfaces that make up each locking ridge 753, the surface on the front side is an inclined surface that is lower on the front side and higher on the back side, and the surface on the back side is a vertical surface.

[0056] In each support blade 720, the upper support member 740 and the lower support member 750 are arranged parallel to each other with the serration portions 742, 752 facing each other. The upper support member 740 and the lower support member 750 are arranged at a predetermined distance and biased toward each other by a pair of springs 770. One spring 770 connects the rear end of the upper support member 740 to the rear end of the lower support member 750. The other spring 770 connects the front end of the upper support member 740 to the front end of the lower support member 750. In each support blade 720, the distance between the upper support member 740 and the lower support member 750 can be increased against the biasing force of the pair of springs 770. The engaging fittings 760 are attached to the rear ends of the upper support member 740 and the lower support member 750. Each support blade 720 can be attached to and detached from the rear plate 701 via the engaging fittings 760. Specifically, each support blade 720 can be attached to the rear plate 701 by engaging the engaging fittings 760 with the engaged portions 701a. Here, as described above, the rear plate 701 is provided with a plurality of engaged portions 701a along the vertical direction. This allows the operator to freely change the position (height) of the support blade 720 attached to the rear plate 701 by attaching each support blade 720 (engaging fitting 760) to an engaged portion 701a at any height among the multiple engaged portions 701a lined up along the vertical direction.

[0057] As shown in FIG. 34, the rod member 730 includes a rod portion 731 and joint portions 732 attached to each end of the rod portion 731 in the longitudinal direction. The rod portion 731 is made of a metal such as aluminum and has a rod-like shape that extends linearly. The cross section of the rod portion 731 that is perpendicular to the longitudinal direction has a flat shape in which the width dimension is greater than the thickness dimension. Each joint portion 732 is formed of resin or the like in a generally cylindrical shape. The central axis of each joint portion 732 is coaxial with the central axis of the rod portion 731. A pair of locking claws (engagement portions) 732a is provided on the outer circumferential surface of each joint portion 732. The pair of locking claws 732a are provided at positions that are point-symmetrical with respect to the central axis of the joint portion 732. That is, on the outer circumferential surface of each joint portion 732, one locking claw 732a is provided at a position 180° opposite to the position at which the other locking claw 732a is provided. Each locking claw 732a is provided so as to protrude outward from the outer circumferential surface of the joint portion 732. In particular, in the rod member 730, the protruding direction of each locking claw 732a coincides with the thickness direction of the rod portion 731, which has a flat cross section.

[0058] The rod member 730 is supported by a pair of support blades 720 so as to be slidable in the front-rear direction. Specifically, the left joint portion 732 of the rod member 730 is supported by the left support blade 720, and the right joint portion 732 of the rod member 730 is supported by the right support blade 720. In this case, each joint portion 732 is sandwiched between a serration portion 742 of the upper support member 740 and a serration portion 752 of the lower support member 750 in each support blade 720, and is supported so as to be slidable along the serration portions 742, 752 (in the front-rear direction). In each fixing unit 710, the rod member 730 can be rotated around its central axis to be displaced between a locked state (see FIG. 33) and an unlocked state (not shown).

[0059] When the rod member 730 is in a locked state, a pair of locking pieces 732a are arranged to protrude upward and downward in each joint portion 732. As a result, in each joint portion 732, the locking piece 732a on one side engages with one of the grooves 744 of the serration portion 742, and the locking piece 732a on the other side engages with one of the grooves 754 of the serration portion 752. As a result, when the rod member 730 is in the locked state, the pair of support blades 720 are locked (prevented) from sliding the rod member 730 toward the front side. That is, in each of the serration portions 742, 752, the rear surface of each locking ridge 753 is a vertical surface. As a result, movement of one locking piece 732a toward the front side is prevented by the rear surface (vertical surface) of the locking ridge 743 provided on the front side of the groove portion 744 with which the locking piece 732a is engaged, and movement of the other locking piece 732a toward the front side is prevented by the rear surface (vertical surface) of the locking ridge 753 provided on the front side of the groove portion 754 with which the locking piece 732a is engaged. Therefore, the rod member 730 is locked (prevented) from sliding toward the front side. On the other hand, even when the rod member 730 is in the locked state, the pair of support blades 720 can push the rod member 730 toward the rear side. That is, in each of the serration portions 742, 752, the front surface of each locking ridge 753 is inclined. As a result, when the rod member 730 is pushed toward the rear side, each locking piece 732a is pushed along the front surface (inclined surface) of each locking ridge 743, 753, thereby widening the gap between the upper support member 740 and the lower support member 750 against the biasing force of the pair of springs 740. Therefore, by pushing the rod member 730 toward the rear side, each locking piece 732a can climb over each locking ridge 743, 753. This allows the rod member 730 to be pushed toward the rear side.

[0060] On the other hand, when the rod member 730 is in the released state, a pair of locking pieces 732a are arranged to protrude forward and backward at each joint portion 732. This releases the engagement of each locking piece 732a with the groove portion 744 at each joint portion 732. This allows the rod member 730 to slide both toward the front and rear sides.

[0061] The display unit 70 is capable of displaying prizes P for refilling. To display the replenishment prizes P, the operator first opens the sliding door on the front of the upper housing 11, shifts the lever 704b from the locked state to the unlocked state, slides the back panel unit 700, which is located in its initial position, toward the front, and places it in any accessible position. Then, shifts the lever 704b from the unlocked state to the locked state. This allows the back panel unit 700 to be locked against forward and backward movement at any accessible position. In this embodiment, by shifting one operating unit 704 from the locked state to the unlocked state using the link mechanism 706, the other operating unit 704 is also shifted from the locked state to the unlocked state, and both of the pair of locking rods 705 can be shifted from the locked position to the unlocked position. This allows the sliding door on the front of the upper housing 11 to be unlocked by the locking mechanism 703 with only one of the right and left sides open. Next, the fixing unit 710 is attached at an arbitrary height to the back plate unit 700. At this time, one or more fixing units 710 are attached to the back plate unit 700 depending on the size and shape of the prize P to be replenished. Next, in each fixing unit 710, the rod member 730 is shifted from the locked state to the unlocked state, slid toward the front, positioned at a desired position, and then shifted from the unlocked state to the locked state. In this embodiment, the cross section of the rod portion 731 perpendicular to the longitudinal direction has a flat shape with a width dimension greater than a thickness dimension. This makes it easy to rotate the rod portion 731, and the rod member 730 can be easily shifted from the locked state to the unlocked state and vice versa. Furthermore, the state of the rod member 730 (locked state / unlocked state) can be confirmed by checking whether the width direction of the rod portion 731 coincides with the up-down direction or the front-to-back direction. Next, after inserting a replenishment prize P between the back plate 701 and the rod member 730 (rod portion 731) of each fixed unit 710, the rod member 730 of each fixed unit 710 is pushed toward the back side. As a result, the replenishment prize P is sandwiched between the back plate 701 and the rod member 730 of each fixed unit 710. Next, lever portion 704b is shifted from the locked state to the unlocked state, and rear panel unit 700 placed in an arbitrary position is slid toward the rear side to be placed in the initial position, and then lever portion 704b is shifted from the unlocked state to the locked state. Thereafter, the sliding door provided on the front of upper housing 11 is closed. This completes the display of the replenishment prizes P in the display unit 70. This makes it possible to display the replenishment prizes P in the display area DE. In this embodiment, each support blade 720 is provided with a plurality of grooves 744, 754 along the front-rear direction, which can engage with the locking claws 732a provided on the rod member 730. This makes it possible to move the position of the rod member 730 on the pair of support blades 720 along the front-rear direction depending on the size and shape of the prize P. This makes it possible to prevent the prize P from falling off the rod member 730. Furthermore, in this embodiment, by rotating the rod member 730, it is possible to engage the locking claw 732a with the grooves 744, 754 or to disengage the locking claw 732a from the grooves 744, 754. This makes it possible to easily engage and disengage the locking claw 732a with the grooves 744, 754. Furthermore, in this embodiment, when the locking claws 732a are engaged with the grooves 744, 754, the rod member 730 is prevented from moving forward, and the rod member 730 can be pushed backward. This makes it possible to easily adjust the position of the rod member 730. Furthermore, in this embodiment, it is possible to sandwich the prize P between the rod member 730 and the back plate 701. This makes it possible to easily display the prize P.

[0062] (Control board 80) Next, the configuration of the control board 80 will be described. FIG. 35 is a block diagram showing the configuration of the control board 80. As shown in FIG. 35, the control board 80 includes a processing unit 81, a storage unit 82, and the like. The processing unit 81 is configured by a microcomputer including a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc. The processing unit 81 executes processing required for the progress of the prize acquisition game based on various detection signals input from the control panel 13, programs and data stored in the memory unit 82, etc. The storage unit 82 is configured with a non-volatile memory, etc. The storage unit 82 stores programs and data required for the progress of the prize acquisition game. Here, the prize acquisition game device 1 is equipped with an X position detection means 83 that detects the position of the prize moving section 210 in the X direction (left and right direction), a Y position detection means 84 that detects the position of the prize moving section 210 in the Y direction (front and back direction), and a Z position detection means 85 that detects the position of the prize moving section 210 in the Z direction (up and down direction). The processing unit 81 receives, as input, a detection signal output in response to tilting of the joystick 16a, a detection signal output in response to pressing of the operation button 16b, and detection signals output by each position detection means 83, 84, 85, etc.

[0063] (Game processing) Next, the game processing executed by the processing unit 81 will be described. When the prize acquisition game device 1 is powered on, the processing unit 81 starts game processing. In the game processing, first, an initial setting process is executed, in which various initial settings are made. Once the initial setting process is complete, an initial operation process is then executed. In the initial operation process, an initial operation is executed for the crane unit 20. The "initial operation" is an operation for checking whether the crane unit 20 is operating normally and for placing the crane unit 20 in the home position. In this embodiment, in the crane unit 20 placed in the home position, the prize moving section 210 is placed above the opening OE, the prize moving section 210 is placed in the raised position, and in each arm unit 240, each arm 241 is placed in the open position. As a result, the three arms 241 in the prize moving section 210 are in an open state, making it possible to attract the attention of surrounding users. When the initial operation process is completed, an attract start process is executed. In the attract start process, the prize acquisition game device 1 starts an attract state (a state of waiting for a customer). In the "attract state," the prize acquisition game is not being executed, and the prize acquisition game can be started. During the attract state, the establishment of the conditions for starting the prize game is monitored. In this embodiment, the conditions for starting the prize game are established when the insertion of a coin into the coin slot 14 is detected. When the conditions for starting the prize acquisition game are met, the attract state is ended and the prize acquisition game (game state) is started. Here, at the start of the prize acquisition game, the crane unit 20 is placed in the home position. During the prize acquisition game, the prize moving section 210 is moved horizontally in response to the tilting operation of the joystick 16a. Then, in response to the pressing operation of the operation button 16b, the movement of the prize moving section 210 along the horizontal direction is stopped, and the crane unit 20 starts the prize acquisition operation. In each prize acquisition operation, first, the prize moving section 210 descends from the raised position to a preset lowered position (hereinafter referred to as the "lowering operation"). Furthermore, upon completion of the lowering operation, in each arm unit 240, the arm lock mechanism 246 releases the lock on the rotation of the arm 241, and the arm 241 rotates from the open position to the closed position (hereinafter referred to as the "arm closing operation"). Furthermore, upon completion of the arm closing operation, the prize moving section 210 ascends from the lowered position to the raised position (hereinafter referred to as the "raising operation"). Furthermore, upon completion of the ascending operation, the prize moving section 210 is moved to above the opening OE (hereinafter referred to as the "opening movement operation"). Furthermore, upon completion of the opening movement operation, in each arm unit 240, the arm 241 rotates from the closed position to the open position (hereinafter referred to as the "arm opening operation"). Furthermore, upon completion of the arm opening operation, this prize acquisition operation ends, and the crane unit 20 returns to the home position. Then, when the crane unit 20 returns to the home position, the current prize acquisition game ends. At this time, if a continuous play is executed, the next prize acquisition game (game state) starts, and if a continuous play is not executed, the attract state starts.

[0064] (Setting various settings) Next, the settings of various setting items will be described. Fig. 36 is a diagram showing an example of the setting screen im1, and Fig. 37 is a diagram showing an example of the area designation screen im2. In the prize winning game device 1, in response to a predetermined operation by the operator, a setting screen im1 shown in Fig. 36 is displayed on the display unit 15b. On the setting screen im1, it is possible to set the operation of the prize moving unit 210 by operating the touch panel 15a. In this embodiment, it is possible to set the arm power at the time of grabbing, the arm power after change, the timing of changing the arm power, the prize drop report, etc. as the operation of the prize moving unit 210. In the following description, of the three arms 241 included in the prize moving section 210, when viewed from the front, the left arm 241 will be referred to as the "left arm," the central arm 241 will be referred to as the "middle arm," and the right arm 241 will be referred to as the "right arm."

[0065] The "grab arm power" is a value that specifies the gripping force (closing force) of each arm 241 in the above-described arm closing operation. In this embodiment, it is possible to set the gripping arm power individually for each of the three arms 241. That is, in the arm closing operation, the gripping force of each arm 241 is controlled so that it becomes a gripping force corresponding to the gripping arm power set for that arm 241. Thereafter, the gripping force corresponding to the gripping arm power is maintained for each arm 241 until the timing for changing the arm power arrives. The "changed arm power" is a value that specifies the gripping force (closing force) of each arm 241 that is set (changed) in response to the arrival of the arm power change timing. In this embodiment, it is possible to set the changed arm power individually for each of the three arms 241. That is, in response to the arrival of the arm power change timing, the gripping force of each arm 241 is controlled so that the gripping force of each arm 241 changes from the gripping force corresponding to the arm power at the time of grasping to the gripping force corresponding to the set changed arm power. Thereafter, the gripping force corresponding to the changed arm power is maintained for each arm 241 until the start of the above-mentioned arm opening operation.

[0066] The "arm power change timing" is the timing at which the gripping force of each arm 241 is changed from the gripping arm power to the changed arm power. In this embodiment, at a predetermined timing during the execution of the above-mentioned lifting operation or at a predetermined timing during the execution of the above-mentioned opening portion moving operation, the gripping force of each arm 241 can be changed from the gripping arm power to the changed arm power. At this time, the gripping force of each arm 241 is changed from the gripping arm power to the changed arm power in response to the arrival of the preset arm power change timing. In this embodiment, the arm power change timings that can be selected and set include a rise start timing, a first rise midway timing, a second rise midway timing, a third rise midway timing, a rise end timing, and an opening movement timing. The "rise start timing" is the time when the rising action starts. That is, the rise start timing occurs when the prize moving section 210 starts rising from the lowered position. The "first mid-rise timing" is when the prize moving section 210 is raised to the first mid-position during the raising operation (when the prize moving section 210 reaches the first mid-position). The "first raised position" is a height (position) that is 1 / 4 of the height from the lowered position to the raised position. The "second mid-rising timing" is when the prize moving section 210 is raised to the second mid-way position during the raising operation (when the prize moving section 210 reaches the second mid-way position). The "second raised position" is half the height (position) of the height from the lowered position to the raised position. The "third mid-rise timing" is when the prize moving section 210 is raised to the third mid-way position during the execution of the raising operation (when the prize moving section 210 reaches the third mid-way position). The "third raised position" is a height (position) that is 3 / 4 of the height from the lowered position to the raised position. The "rise end timing" is the time when the rise operation ends. In other words, the rise end timing is when the prize moving section 210 is raised to the rise position (when the prize moving section 210 reaches the rise position). The "opening portion movement timing" is a predetermined timing during the opening portion movement operation. In this embodiment, the opening portion movement timing is the time when a predetermined time (for example, 0.5 [s]) has elapsed from the start of the opening portion movement operation.

[0067] In this embodiment, when the arm power change timing arrives, it is possible to change the gripping force of each arm 241 from a gripping force corresponding to the arm power at the time of gripping to a gripping force corresponding to the changed arm power. This allows the changed arm power to be set to a gripping force that is weaker than the arm power at the time of gripping, so that during the execution of the prize acquisition action, after the prize P is gripped by the three arms 241, the prize P being gripped can be dropped (hereinafter referred to as "prize dropping action"), thereby improving the fun of the game. In particular, in this embodiment, the changed arm power can be set individually for each of the three arms 241. This makes it possible to arbitrarily set (control) the direction in which the prize P falls during the prize dropping action, further improving the enjoyment of the game. For example, by setting the changed arm power of the left arm to a weaker gripping force than the changed arm power of the right arm, the direction in which the prize P falls during the prize dropping action can be set to the left. On the other hand, by setting the changed arm power of the right arm to a weaker gripping force than the changed arm power of the left arm, the direction in which the prize P falls during the prize dropping action can be set to the right. On the other hand, by setting the same gripping force for the changed arm power of the left arm and the changed arm power of the right arm, the direction in which the prize P falls during the prize dropping action can be set to directly below.

[0068] The "prize falling direction" is the direction in which the prize P falls during the prize falling action. In this embodiment, the prize drop direction that can be selected and set is provided as left drop, right drop, and straight down. When any of left drop, right drop, and straight down is selected and set as the prize drop direction, a preset value is automatically selected and set as the changed arm power of each arm 241. At this time, if "left drop" is selected and set, the changed arm power of each arm 241 is automatically selected and set so that the direction in which the prize P falls during the prize drop operation is to the left. On the other hand, when "right drop" is selected and set, the changed arm power of each arm 241 is automatically selected and set so that the direction in which the prize P falls during the prize drop operation is to the right. On the other hand, when "straight down" is selected and set, the changed arm power of each arm 241 is automatically selected and set so that the direction in which the prize P falls during the prize dropping operation is straight down.

[0069] Here, a method for controlling the gripping force of each arm 241 based on the set arm power (arm power at the time of gripping and arm power after change) will be described. In this embodiment, a command value table in which the correspondence between arm power and command value is registered is stored in the ROM of the processing unit 81. Then, the processing unit 81 acquires a command value corresponding to the set arm power (arm power at the time of gripping and arm power after change) for each arm 241 based on the command value table, calculates a current value of the open / close motor m4 using a predetermined calculation formula based on the acquired command value, and controls the drive of the open / close motor m4 in accordance with the calculated current value. At this time, the value obtained by A / D converting the current of the open / close motor m4 is monitored, and the drive of the open / close motor m4 is controlled by changing the output duty of the open / close motor m4 so that the calculated current value is achieved.

[0070] As shown in Figure 36, the setting screen im1 is configured with an arm power selection section A1 when grabbing the left arm, an arm power selection section A2 when grabbing the middle arm, an arm power selection section A3 when grabbing the right arm, an arm power selection section B1 after changing the left arm, an arm power selection section B2 after changing the middle arm, an arm power selection section B3 after changing the right arm, an arm power change timing selection section C, and a drop direction selection section D. The left arm gripping arm power selection section A1 displays a value indicating the gripping arm power set for the left arm. The operator can select (set / change) the left arm gripping arm power by operating the touch panel 15a. In this case, by tapping the left arm gripping arm power selection section A1, it is possible to select (set / change) any value (step) in increments of "1" within the range of "1" (weak) to "150" (strong) for the left arm gripping arm power. The middle arm gripping arm power selection section A2 displays a value indicating the gripping arm power set for the middle arm. The operator can select (set / change) the gripping arm power of the middle arm by operating the touch panel 15a. At this time, by tapping the middle arm gripping arm power selection section A2, it is possible to select (set / change) any value (step) in increments of "1" within the range of "1" (weak) to "150" (strong) for the gripping arm power of the middle arm. The right arm gripping arm power selection section A3 displays a value indicating the gripping arm power set for the right arm. The operator can select (set / change) the gripping arm power of the right arm by operating the touch panel 15a. In this case, by tapping the right arm gripping arm power selection section A3, it is possible to select (set / change) any value (step) in increments of 1 within the range of "1" (weak) to "150" (strong) for the gripping arm power of the right arm.

[0071] The left arm post-change arm power selection section B1 displays a value indicating the post-change arm power set for the left arm. The operator can select (set / change) the post-change arm power of the left arm by operating the touch panel 15a. At this time, by tapping the left arm post-change arm power selection section B1, it is possible to select (set / change) any value (step) in increments of "1" within the range of "1" (weak) to "150" (strong) for the post-change arm power of the left arm. The middle arm post-change arm power selection section B2 displays a value indicating the post-change arm power set for the middle arm. The operator can select (set / change) the post-change arm power of the middle arm by operating the touch panel 15a. At this time, by tapping the middle arm post-change arm power selection section B2, it is possible to select (set / change) any value (step) in increments of "1" within the range of "1" (weak) to "150" (strong) for the post-change arm power of the middle arm. The right arm post-change arm power selection section B3 displays a value indicating the post-change arm power set for the right arm. The operator can select (set / change) the post-change arm power of the right arm by operating the touch panel 15a. At this time, by tapping the right arm post-change arm power selection section B3, it is possible to select (set / change) any value (step) in increments of "1" within the range of "1" (weak) to "150" (strong) for the post-change arm power of the right arm.

[0072] The arm power change timing selection section C displays information indicating the set arm power change timing. The operator can select (set / change) the arm power change timing by operating the touch panel 15a. At this time, the arm power change timing selection section C displays an icon corresponding to the ascent start timing, an icon corresponding to the first ascent midway timing, an icon corresponding to the second ascent midway timing, an icon corresponding to the third ascent midway timing, an icon corresponding to the ascent end timing, and an icon corresponding to the opening movement timing. By tapping each icon, it is possible to select (set) the arm power change timing corresponding to that icon, or to cancel the selection (setting) of the arm power change timing corresponding to that icon. In this embodiment, it is possible to select (set) one or more of six timings (start of ascent timing, first mid-ascent timing, second mid-ascent timing, third mid-ascent timing, end of ascent timing, and opening movement timing) as the arm power change timing. When one arm power change timing is selected (set), in each prize acquisition operation, the gripping force of each arm 241 is changed from the arm power at the time of grabbing to the changed arm power according to the arrival of the selected (set) arm power change timing. On the other hand, when multiple arm power change timings are selected (set), one of the multiple selected (set) arm power change timings is randomly selected for each prize acquisition operation, and when the selected arm power change timing arrives, the gripping force of each arm 241 is changed from the arm power at the time of grabbing to the changed arm power. Note that when multiple arm power change timings are selected (set), a configuration may be adopted in which the gripping force of each arm 241 is gradually changed from the arm power at the time of grasping to the post-change arm power each time an arm power change timing arrives. In such a configuration, a decrease in the gripping force of each arm 241 begins by a predetermined decrease width (the magnitude of the gripping force of each arm 241 decreased per unit time) each time an arm power change timing arrives. In this case, a configuration may be adopted in which the decrease width of the gripping force (the magnitude of the gripping force of each arm 241 decreased per unit time) can be arbitrarily set for each arm power change timing.

[0073] The prize drop direction selection section D displays the set prize drop direction. The operator can select (set / change) the prize drop direction by operating the touch panel 15a. At this time, the drop direction selection section D displays an icon corresponding to a left drop, an icon corresponding to a right drop, and an icon corresponding to a straight down drop. By tapping each icon, the prize drop direction corresponding to the icon can be selected (set). In this embodiment, it is possible to select (set) any one of three prize drop directions (left drop, right drop, and straight down). When any one of the prize drop directions is selected (set), in each prize acquisition operation, the gripping force of each arm 241 is changed to a gripping force corresponding to the selected (set) prize drop direction according to the timing for changing the arm power.

[0074] On the setting screen im1, the operator can arbitrarily change the set values (information) for the arm power when grabbing the left arm, the arm power when grabbing the middle arm, the arm power when grabbing the right arm, the arm power after change to the left arm, the arm power after change to the middle arm, the arm power after change to the right arm, the timing of the arm power change, and the direction in which the prize falls. In particular, in this embodiment, the setting screen im1 divides the game area GE into a plurality of designated areas, and for each designated area, it is possible to set the operation of the prize moving unit 210. In this case, in this embodiment, it is possible to set the arm power at the time of grabbing the left arm, the arm power at the time of grabbing the middle arm, the arm power at the time of grabbing the right arm, the arm power after change to the left arm, the arm power after change to the middle arm, the arm power after change to the right arm, the timing of the arm power change, and the prize falling direction as the operation of the prize moving unit 210. As a result, when a prize acquisition operation is started in each designated area, the prize acquisition operation is executed in accordance with the information selected (set) for that designated area (arm power at the time of grabbing the left arm, arm power at the time of grabbing the middle arm, arm power at the time of grabbing the right arm, arm power after change to the left arm, arm power after change to the middle arm, arm power after change to the right arm, timing of the arm power change, and prize drop direction).

[0075] Specifically, an area designation icon ic1 is displayed on the setting screen im1. When the area designation icon ic1 is selected by operating the touch panel 15a, an area designation screen im2 is displayed on the display unit 15b. As shown in Fig. 37, the area designation screen im2 allows one or more designated areas to be designated in the game area GE. Specifically, the area designation screen im2 allows the game area GE to be divided into multiple designated areas. After dividing the game area GE into multiple designated areas on the area designation screen im2, the operation of the prize moving unit 210 can be set for each divided designated area on the setting screen im1. That is, the area designation screen im2 displays a set area ge corresponding to the game area GE, and three area division lines L1 to L3 that divide the set area ge (game area GE) into multiple designated areas. By operating the touch panel to move each of the area division lines L1 to L3, it is possible to designate (set) up to six designated areas in the set area ge (game area GE). In this case, when one designated area is designated (set), the entire set area ge (game area GE) becomes that one designated area. On the other hand, when two or more designated areas are designated (set), the set area ge (game area GE) is divided into two or more designated areas. The setting screen im1 displays an image (hereinafter referred to as a "designated area setting status image d") showing the setting status of the designated area in the setting region ge (game area GE) that has been designated (set) on the area designation screen im2. In this embodiment, the area designation icon ic1 includes the designated area setting status image d. The setting screen im1 also displays designated area icons ic3 corresponding to each designated area that has been designated (set) on the area designation screen im2. Here, in the designated area setting status image d, the multiple designated areas are assigned different colors, and each designated area icon ic3 is assigned the same color as the designated area corresponding to that designated area icon ic3. Then, on the setting screen im1, when each designated area icon ic3 is selected by operating the touch panel 15a, the arm power selection sections A1, A2, A3, B1, B2, B3 and the arm power change timing selection section C display the information set for the designated area corresponding to that designated area icon ic3 (arm power when grabbing with the left arm, arm power when grabbing with the middle arm, arm power when grabbing with the right arm, arm power after change to the left arm, arm power after change to the middle arm, arm power after change to the right arm, arm power change timing, and prize drop direction), and it is possible to change the set information (values) as desired.

[0076] In this embodiment, it is possible to set the changed arm power individually for each of the multiple arms 241. This makes it possible to drop the prizes P held by the multiple arms 241 in response to the arrival of the arm power change timing, and in particular, it becomes possible to arbitrarily set the direction in which the prizes P will fall. Therefore, it becomes possible to gradually move the prizes P in a predetermined direction with each play, which makes it possible to improve the enjoyment of the game. In addition, in this embodiment, it is possible to set any one of a plurality of predetermined timings (rise start timing, first rise midway timing, second rise midway timing, third rise midway timing, rise end timing, and opening movement timing) as the arm power change timing. This makes it possible to arbitrarily set the timing at which the prize P held by the plurality of arms 241 is dropped. In this embodiment, the set area ge (game area GE) is divided into a plurality of designated areas, and it is possible to set the changed arm power for each of the designated areas individually. This makes it possible to set the direction in which the prize P falls for each designated area according to the timing for changing the arm power, further improving the enjoyment of the game. Furthermore, in this embodiment, even if the setting region ge (game area GE) is divided into two or more designated areas, it is possible to set the operation of the prize moving unit 210 (arm power at the time of grabbing the left arm, arm power at the time of grabbing the middle arm, arm power at the time of grabbing the right arm, arm power after change to the left arm, arm power after change to the middle arm, arm power after change to the right arm, arm power change timing, and prize drop direction) for each designated area on one screen (specifically, setting screen im1). This eliminates the need to transition to a different screen for each designated area when setting the operation of the prize moving unit 210 for each designated area, thereby improving convenience. In particular, it becomes easy to compare the operation of the prize moving unit 210 set for each designated area for multiple designated areas, thereby improving convenience.

[0077] (Variation) Although the embodiment of the present invention has been described above, various modifications can be made to the above embodiment. For example, in the above embodiment, it is possible to designate one or more designated areas in the game area GE on the area designation screen im2. That is, it is possible to divide the game area GE into multiple designated areas on the area designation screen im2. However, the setting screen im1 may be configured to allow one or more designated areas to be designated in the game area GE. In other words, the setting screen im1 may be configured to allow the game area GE to be divided into multiple designated areas.

[0078] (Function of Prize Acquisition Game Device 1) The prize game device 1 is a prize game device that allows a player to win a prize P that has dropped into the prize storage section CS, and is equipped with a prize outlet 17 that allows the player to take out the prize P that has dropped into the prize storage section CS, an opening / closing door 610 that can open and close the prize outlet 17, and a shutter plate 620 member that can open and close at least a portion of the opening that leads from the prize storage section CS to the game area GE. As the opening / closing door 610 opens and closes, at least a portion of the opening is opened and closed by the shutter plate 620. That is, in the prize acquisition game device 1, as the opening and closing door 610 opens and closes, at least a part of the opening leading from the prize storage section CS to the game area GE is opened and closed by the shutter plate 620. This makes it possible to prevent fraudulent acts such as reaching in through the prize outlet 17 to take a prize P placed in the game area GE. In particular, in the prize acquisition game device 1, when the opening / closing door 610 is opened, at least a part of the opening is closed by the shutter plate 620. This makes it possible to prevent fraudulent acts of acquiring prizes P placed in the game area GE. Furthermore, in the prize acquisition game device 1, when the opening / closing door 610 is closed, the shutter plate 620 is positioned so as not to obstruct the passage of the prize P through the opening. This makes it possible to prevent the shutter plate 620 from obstructing the acquisition of the prize P. Furthermore, in the prize acquisition game device 1, when the opening / closing door 610 is opened, the opening is closed by the opening / closing door 610 and the shutter plate 620. This makes it possible to close the opening with a simple configuration. [Explanation of symbols]
