The various operation devices may include a firing handle, an effect operation button, and a counting switch.

[0015] The game board YB has a game area where game balls flow down. A plurality of winning openings are open in the game area. For example, the winning openings include a start winning opening and a big winning opening. The display device DS displays a variable game accompanied by a variable display of symbols. The control device CU has a substrate and a case. A processor and a memory are mounted on the substrate. The control device CU protrudes rearward from the rear end of the fixed frame KW at the rear side of the game board YB. The height dimension and the width dimension of the control device CU are smaller than the height dimension Ph and the width dimension Pw of the fixed frame KW, respectively.

[0016] The processor of the control device CU manages the number a2 of game media, which are the player's balls in hand. When a game ball is fired in response to an operation of the firing handle, the processor subtracts the number a2 of game media. When a game ball enters the start winning opening, the processor conducts a jackpot lottery. When winning the jackpot in the jackpot lottery, the processor derives a jackpot symbol in the variable game and gives a jackpot game. In the jackpot game, the processor opens the big winning opening. When a game ball enters each winning opening, the processor adds the number determined for the winning opening to the number a2 of game media.

[0017] When the counting switch is operated, the processor subtracts the number of transferred gaming media from the number of gaming media a2. The processor transmits counting information that can identify the number of transferred media to the management unit 30. The processor receives payout information that can identify the number of paid-out gaming balls. The processor adds the number of paid-out balls that can be identified from the payout information to the number of gaming media a2.

[0018] (Rotary Reel Gaming Machine) As shown in FIGS. 1, 2, and 4, the gaming machine 20S is a medal-less gaming machine that does not use gaming medals as gaming media.

Note that the gaming machine 20S may be a non-medal-less gaming machine that uses gaming medals as gaming media. The height dimension Sh of the gaming machine 20S is the same as or substantially the same as the height dimension Ph of the gaming machine 20P. The width dimension Sw of the gaming machine 20S is smaller than the width dimension Pw of the gaming machine 20P. That is, the gaming machine 20P is wider than the gaming machine 20S.

[0019] The gaming machine 20S includes a housing B, a front door, a plurality of reels, various operation devices, and a control device. The housing B is in the shape of a rectangular box having an opening on the player side in the depth direction Dd. That is, the housing B has a rear wall on the side opposite to the player side in the depth direction Dd. The rear side of the housing B is sealed by the rear wall. The housing B is an example of a main box fixed to the island facility 10. The front door is pivotally supported at the left edge of the opening in the housing B. The front door can open and close the opening of the housing B by unlocking a locking device (not shown). The front door is an example of a door portion that can open and close with respect to the housing B. A plurality of symbols are arranged on the plurality of reels. As an example, the various operation devices may include a stop button, a start lever, a bet button, and a counting switch. The control device includes a substrate and a case. A processor and a memory are mounted on the substrate. The plurality of reels and the control device are housed in the housing B.

[0020] The processor of the control device manages the number of gaming media a2, which is the player's credit. The processor of the control device increases the bet amount in response to the operation of the bet button. The processor subtracts the number of gaming media a2 in response to the increase in the bet amount. The processor rotates the reels in response to the operation of the start lever. That is, the variable game is started. The processor stops the reels in response to the operation of the stop button. When all the reels stop and a specific symbol combination is displayed, the processor adds the number corresponding to the symbol combination to the number of gaming media a2.

[0021] When the counting switch is operated, the processor subtracts the number of transferred gaming media from the number of gaming media a2. The processor transmits the counting information that can identify the number of transferred gaming media to the management unit 30. The processor receives the payout information that can identify the payout number of the gaming media. The processor adds the payout number that can be identified from the payout information to the number of gaming media a2.

[0022] (Recommended height when installing the gaming machine) In the island facility 10, the recommended installation height (hereinafter referred to as the recommended height) of the gaming machine 20 varies depending on the type of the gaming machine 20. The recommended height of the gaming machine 20 is set to a height at which various operation devices arranged on the gaming machine 20 can be easily operated when the player is sitting on a chair. As an example, the recommended height HS of the gaming machine 20S is lower than the recommended height HP of the gaming machine 20P. The recommended height HS of the gaming machine 20S is such that the height from the installation surface G of the island facility 10 to the bottom surface of the gaming machine 20S is preferably 450 mm to 550 mm, more preferably 490 mm to 510 mm, and even more preferably 500 mm.

[0023] (Management unit) As shown in FIGS. 1, 5, and 6, the management unit 30 includes a housing 30B. The housing 30B is formed by bending a steel plate or the like and has a rectangular box shape. The management unit 30 has an insertion port into which a management medium can be inserted. As an example, the management medium is an IC card or an IC coin. The management medium stores the remaining amount of the inserted money and the number a1 of gaming media held by the player. The management unit 30 has a payout operation unit as an example of an operation device. When a payout operation of the gaming media is performed using the payout operation unit, the management unit 30 transmits payout information to the gaming machine 20. When the management unit 30 receives the counting information, it adds the transfer number that can be specified from the counting information to the number a1 of gaming media stored in the management medium.

[0024] As an example, the management unit 30 includes a management unit 30N and a management unit 30W. The management unit 30N and the management unit 30W are examples of a first external device. The management unit 30N is an example of a first external device of a first type. The management unit 30W is an example of a first external device of a second type. As an example, the management unit 30N has a bill insertion port Na on the player side (front side) of the housing 30B. As an example, the management unit 30N incorporates a bill discriminator 30Nb. The bill discriminator 30Nb discriminates the type and authenticity of the bill inserted through the bill insertion port Na. When the bill discriminator 30Nb determines that the bill is a counterfeit bill or cannot be identified, it returns the inserted bill from the bill insertion port Na. As an example, the management unit 30N has a bill discharge port Nc on the side opposite to the player side (rear side) of the housing 30B. When the bill discriminator 30Nb determines that the bill is not a counterfeit bill, it discharges the inserted bill from the bill discharge port Nc. When a bill is inserted, the management unit 30 adds it to the remaining amount stored in the management medium.

[0025] As an example, the management unit 30W does not have a banknote insertion slot. As an example, the management unit 30W does not incorporate a banknote discriminator. As an example, the management unit 30W is connected to the banknote discrimination unit 31. When the management unit 30W receives the inserted amount information from the banknote discrimination unit 31, it adds it to the balance stored in the management medium. After adding it to the balance stored in the management medium, when a payout operation of the gaming medium is performed using the payout operation unit, the management unit 30W transmits the payout information to the gaming machine 20.

[0026] The height dimension Nh of the management unit 30N and the height dimension Wh of the management unit 30W are the same or substantially the same. The width dimension Ww of the management unit 30W is larger than the width dimension Nw of the management unit 30N. That is, the management unit 30W is longer in the length along the width direction Dw than the management unit 30N. As an example, the width dimension Nw of the management unit 30N may be 40 mm, and the width dimension Ww of the management unit 30W may be 100 mm. The height dimension Nh of the management unit 30N is the same or substantially the same as the height dimension Ph of the gaming machine 20P and the height dimension Sh of the gaming machine 20S. The height dimension Wh of the management unit 30W is the same or substantially the same as the height dimension Ph of the gaming machine 20P and the height dimension Sh of the gaming machine 20S.

The width dimension Hwb of the space S1b is slightly larger than the width dimension Pw of the gaming machine 20P. The separation distance along the width direction Dw between the inner surface 46b of the first protrusion 46 and the inner surface 47b of the second protrusion 47 is the width dimension Hwa of the space S1a. The width dimension Hwa of the space S1a is smaller than the width dimension Pw of the gaming machine 20P and smaller than the width dimension Hwb of the space S1b. However, the width dimension Hwa is larger than the width dimension of the portion (control device CU) that protrudes rearward of the gaming machine 20P. The separation distance along the height direction Dh between the inner surface 43b of the first base 43 and the surface 45b of the third base 45 is the height dimension Hh of the space S1. The height dimension Hh of the space S1 is slightly larger than the height dimension Ph of the gaming machine 20P. Therefore, the space S1b has a shape corresponding to the outer shape of the gaming machine 20P and is large enough to accommodate the gaming machine 20P. The space S1a is large enough to accommodate the control device CU, but is not large enough to accommodate the entire gaming machine 20P.

[0042] The width dimension Hwb of the space S1b is larger than the width dimension Sw of the gaming machine 20S. The width dimension Hwa of the space S1a is slightly larger than the width dimension Sw of the gaming machine 20S and smaller than the width dimension Pw of the gaming machine 20P. The height dimension Hh of the space S1 is slightly larger than the height dimension Sh of the gaming machine 20S. Therefore, the spaces S1a and S1b have a shape corresponding to the outer shape of the gaming machine 20S and are large enough to accommodate the gaming machine 20S. The inner surface 46b of the first protrusion 46 and the inner surface 47b of the second protrusion 47 are closer to the side wall surface of the housing B than the inner surface 41b of the first side wall 41 and the inner surface 42b of the second side wall 42. Thus, the gaming machine frame 40 has an installation portion where the gaming machine 20 can be installed by the side walls 41, 42, the protrusions 46, 47, and the bases 43, 45, and the installation portion is open at both ends in the depth direction Dd. The gaming machine 20P is installed by fixing the fixed frame KW to the installation portion. The gaming machine 20S is installed by fixing the housing B to the installation portion.

[0043] When the gaming machine frame 40 is installed in the posture P2, the height Hka from the installation surface G to the surface 45a of the third base 45 is lower than the height Hja from the installation surface G to the lower end portion 32bb of the bill transport unit 32b. When the gaming machine frame 40 is installed in the posture P2, the height Hkb from the installation surface G to the inner surface 44b of the second base 44 is higher than the height Hjb from the installation surface G of the island facility 10 to the upper end portion 32ba of the bill transport unit 32b. Therefore, when the inspection door Dr is opened when the gaming machine frame 40 is installed in the posture P2, the space S2 communicates the inside and outside of the island facility 10, and at least a part of the bill transport unit 32b (bill transport path) can be visually recognized in a front view. Thus, it can be said that the height of the space S2 corresponds to the height of the bill transport unit 32b. In this way, the gaming machine frame 40 has an opening through which at least a part of the bill transport unit 32b arranged inside the island facility 10 can be visually recognized.

[0044] The first surface M1 is constituted by one end surface among the end surfaces of the side walls 41, 42 and the bases 43 to 45 in the depth direction Dd. The first surface M1 is constituted to include one surface among the two surfaces of the inspection door Dr in the depth direction Dd. The second surface M2 is constituted by the other end surface among the end surfaces of the side walls 41, 42 and the bases 43 to 45 in the depth direction Dd. The second surface M2 is constituted to include the other surface among the two surfaces of the inspection door Dr in the depth direction Dd. The first surface M1 and the second surface M2 are each decorated. The first surface M1 and the second surface M2 are decorated with different decorations. As an example, the decoration may be characters, landscapes, patterns, and letters drawn using paint or the like on each of the surfaces M1, M2. The decoration may be characters, landscapes, patterns, and letters drawn on a sheet attached to each of the surfaces M1, M2.

[0045] (Unit frame) The island equipment 10 includes a plurality of unit frames 50 capable of holding a management unit 30 and a banknote discrimination unit 31 respectively. Each unit frame 50 can hold a prescribed number of management units 30 and a prescribed number of banknote discrimination units 31. The unit frame 50 is an example of a holding part for the management unit 30 capable of holding a plurality of types of external devices. As an example, the prescribed number is 1. That is, each unit frame 50 can hold one management unit 30 and one banknote discrimination unit 31. Each unit frame 50 is configured to be able to hold either the management unit 30N or the management unit 30W. That is, in the island equipment 10, each unit frame 50 can be installed in a state of holding one management unit 30N or one management unit 30W and one banknote discrimination unit 31. Since each unit frame 50 has the same configuration, one of them will be described in detail.

[0046] As shown in FIGS. 1, 2, 5(a) to 5(c), and FIGS. 6(a) to 6(c), the unit frame 50 is a rectangular frame member extending along the height direction Dh. The unit frame 50 is open at both ends in the depth direction Dd. The unit frame 50 is installed in the posture p1 or the posture p2. The posture p1 is a posture in which the end e1 of the unit frame 50 in the height direction Dh is arranged on the upper side and the opposite end e2 is arranged on the lower side. The posture p1 is a posture in which the first surface m1 of the unit frame 50 in the depth direction Dd is arranged on the player side and the opposite second surface m2 is arranged inside the island equipment 10. The posture p2 is a posture in which the end e2 of the unit frame 50 is arranged on the upper side and the end e1 is arranged on the lower side. The posture p2 is a posture in which the second surface m2 is arranged on the player side and the first surface m1 is arranged inside the island equipment 10. The first surface m1, which is an end of the unit frame 50 in the depth direction Dd, is an example of the first end. The second surface m2, which is an end of the unit frame 50 in the depth direction Dd, is an example of the second end. Thus, the installation modes of the unit frame 50 include a first mode (posture p1) in which the first surface m1 of the unit frame 50 is arranged on the player side and a second mode (posture p2) in which the second surface m2 opposite to the first surface m1 is arranged on the player side.

[0047] The unit frame 50 is an example of a member that can accommodate the replacement of the management unit 30N and the management unit 30W. The posture p1 is a posture suitable for installing the management unit 30N. In the island facility 10, when the management unit 30N is held with the unit frame 50 in the posture p1, the management unit 30N is installed so as to have the recommended height HN (see FIG. 1). The posture p2 is a posture suitable for installing the management unit 30W. In the island facility 10, when the management unit 30W is held with the unit frame 50 in the posture p2, the management unit 30W is installed so as to have the recommended height HW (see FIG. 1).

[0048] The unit frame 50 includes a first side wall 51 and a second side wall 52 as parts constituting the side walls of the unit frame 50. The side walls 51 and 52 are flat plate-like parts extending along the height direction Dh. The side walls 51 and 52 extend parallel or substantially parallel to each other as side walls arranged along the width direction Dw. The side walls 51 and 52 face each other with a space s interposed therebetween in the width direction Dw. The inner surface 51b of the first side wall 51 and the inner surface 52b of the second side wall 52 face each other with the space s interposed therebetween.

[0049] The unit frame 50 includes a first base 53 and a second base 54 as parts constituting the ceiling or bottom of the unit frame 50. The bases 53 and 54 are flat plate-like parts extending along the width direction Dw. The bases 53 and 54 extend parallel or substantially parallel to each other. The first base 53 is connected at the end e1 of the unit frame 50 so as to connect the ends of the side walls 51 and 52. It can also be said that the first base 53 constitutes the end e1 of the unit frame 50. The second base 54 is connected at the end e2 of the unit frame 50 so as to connect the ends of the side walls 51 and 52. It can also be said that the second base 54 constitutes the end e2 of the unit frame 50. The bases 53 and 54 face each other with a space s interposed therebetween in the height direction Dh.

[0050] The unit frame 50 includes a third base 55 that is connected between the bases 53 and 54 so as to connect the side walls 51 and 52. The third base 55 is a flat plate-like portion extending along the width direction Dw. The third base 55 extends parallel or substantially parallel to the bases 53 and 54. The direction in which the bases 53 to 55 extend and the direction in which the side walls 51 and 52 extend intersect each other, and more preferably are orthogonal to each other. The third base 55 divides the space s surrounded by the side walls 51 and 52 and the bases 53 and 54 in the height direction Dh to form a space s1 and a space s2. As will be described later, the space s1 becomes a space for accommodating the management units 30N and 30W. The space s2 becomes a space for accommodating the banknote discrimination unit 31. The inner surface 53b of the first base 53 and the surface 55b of the third base 55 face each other with the space s1 therebetween. The inner surface 54b of the second base 54 and the surface 55a of the third base 55 face each other with the space s2 therebetween. The space s2 is an example of a third space.

[0051] The unit frame 50 includes a first protrusion 56 that protrudes from the inner surface 51b of the first side wall 51 into the space s. The unit frame 50 includes a second protrusion 57 that protrudes from the inner surface 52b of the second side wall 52 into the space s. The protrusions 56 and 57 are respectively provided along the edge portions on the first surface m1 side of the side walls 51 and 52. The protrusions 56 and 57 are each a prismatic portion extending along the height direction Dh. The protrusions 56 and 57 are provided between the inner surface 53b of the first base 53 and the surface 55b of the third base 55. That is, the protrusions 56 and 57 extend from the upper end to the lower end of the space s1. The protrusions 56 and 57 face each other across the space s1 from the width direction Dw. The inner surface 56b of the first protrusion 56 and the inner surface 57b of the second protrusion 57 face each other with the space s1 therebetween. The portion of the space s1 sandwiched between the inner surface 56b of the first protrusion 56 and the inner surface 57b of the second protrusion 57 is the space s1a. The portion of the space s1 excluding the space s1a is the space s1b. The space s1a is an example of a first space. The space s1b is an example of a second space.

[0052] The height dimension UH of the unit frame 50 is larger than the width dimension UW of the unit frame 50. The separation distance along the width direction Dw between the inner surface 51b of the first side wall 51 and the inner surface 52b of the second side wall 52 is the width dimension Uwb of the space s1b. The width dimension Uwb of the space s1b is slightly larger than the width dimension Ww of the management unit 30W. The separation distance along the width direction Dw between the inner surface 56b of the first protrusion 56 and the inner surface 57b of the second protrusion 57 is the width dimension Uwa of the space s1a. The width dimension Uwa of the space s1a is smaller than the width dimension Ww of the management unit 30W and smaller than the width dimension Uwb of the space s1b. The separation distance along the height direction Dh between the inner surface 53b of the first base 53 and the surface 55b of the third base 55 is the height dimension Uh of the space s1. The height dimension Uh of the space s1 is slightly larger than the height dimension Wh of the management unit 30W. Therefore, the space s1b has a shape corresponding to the outer shape of the management unit 30W and is large enough to accommodate the management unit 30W. Thus, in the unit frame 50, a space s1b for accommodating the management unit 30W is formed between the first side wall 51 and the second side wall 52. Therefore, in the island facility 10, the management unit 30W can be accommodated in the space s1b when the unit frame 50 is installed in the posture p2.

[0053] The width dimension Uwb of the space s1b is larger than the width dimension Nw of the management unit 30N. The width dimension Uwa of the space s1a is slightly larger than the width dimension Nw of the management unit 30N while being smaller than the width dimension Ww of the management unit 30W. The height dimension Uh of the space s1 is slightly larger than the height dimension Nh of the management unit 30N. Therefore, the spaces s1a and s1b have shapes corresponding to the outer shape of the management unit 30N and are large enough to accommodate the management unit 30N. The inner surface 56b of the first protrusion 56 and the inner surface 57b of the second protrusion 57 are closer to the side wall surface of the management unit 30N than the inner surface 51b of the first side wall 51 and the inner surface 52b of the second side wall 52. Thus, in the unit frame 50, a space s1a for accommodating the management unit 30N is formed between the first side wall 51 and the second side wall 52. Therefore, in the island facility 10, the management unit 30N can be accommodated in the space s1a when the unit frame 50 is installed in the posture p1.

[0054] When the unit frame 50 is installed in the posture p1 and the management unit 30N is installed, the height of the management unit 30N becomes the recommended height HN. When assuming a perspective view from the front, the recommended height HN of the management unit 30N is the height at which all or substantially all of the banknote inlet 32c and the banknote outlet Nc overlap each other. Not limited to this, when assuming a perspective view from the front, the recommended height HN of the management unit 30N may be the height at which a part of the banknote inlet 32c and the banknote outlet Nc overlap each other. That is, the recommended height HN of the management unit 30N is the height at which the banknote inlet 32c can receive the banknotes discharged from the banknote outlet Nc. For example, the recommended height HN of the management unit 30N may be the height at which the banknotes discharged from the banknote outlet Nc are received into the banknote inlet 32c horizontally or substantially horizontally in the depth direction Dd.

[0055] The separation distance along the width direction Dw between the inner surface 51b of the first side wall 51 and the inner surface 52b of the second side wall 52 is the width dimension Uwb of the space s2. Note that the width dimension of the space s1b and the width dimension of the space s2 may be different or the same. The width dimension Uwb of the space s2 is slightly larger than the width dimension Vw of the banknote discrimination unit 31. The separation distance along the height direction Dh between the inner surface 54b of the second base 54 and the surface 55a of the third base 55 is the height dimension Ah of the space s2. The height dimension Ah of the space s2 is slightly larger than the height dimension Vh of the banknote discrimination unit 31. Therefore, the space s2 has a shape corresponding to the outer shape of the banknote discrimination unit 31 and a size capable of accommodating the banknote discrimination unit 31. Thus, in the unit frame 50, a space s2 for accommodating the banknote discrimination unit 31 is formed between the first side wall 51 and the second side wall 52. And the space s2 communicates the inside and outside of the island facility 10. The width dimension Uwb of the space s2 is the same or substantially the same dimension between the first surface m1 and the second surface m2. The height dimension Ah of the space s2 is the same or substantially the same dimension between the first surface m1 and the second surface m2. Therefore, the banknote discrimination unit 31 can be accommodated in the space s2 regardless of whether the unit frame 50 is installed in the posture p1 or the posture p2.

[0056] When the unit frame 50 is installed in the posture p2 and the banknote discrimination unit 31 is installed, the height of the banknote discrimination unit 31 becomes the recommended height Hv. When assuming a perspective view from the front, the recommended height Hv of the banknote discrimination unit 31 is a height at which all or substantially all of the banknote inlet 32c and the banknote outlet Nc overlap each other. The recommended height Hv of the banknote discrimination unit 31 is a height at which the banknote inlet 32c can receive the banknotes discharged from the banknote outlet 31M. Therefore, it can be said that the height of the space s2 is a height corresponding to the height of the banknote conveyance unit 32. Accordingly, it can also be said that the height of the space s2 is a height corresponding to the banknote conveyance section 32b (banknote conveyance path).

[0057] The first surface m1 is constituted by one end surface among the end surfaces of the side walls 51 and 52 and the base portions 53 to 55 in the depth direction Dd. The second surface m2 is constituted by the other end surface among the end surfaces of the side walls 51 and 52 and the base portions 53 to 55 in the depth direction Dd. The first surface m1 and the second surface m2 are each decorated. The first surface m1 and the second surface m2 are decorated with different decorations. As an example, the decoration may be characters, landscapes, patterns, and letters drawn using paint or the like on each of the surfaces m1 and m2. The decoration may be characters, landscapes, patterns, and letters drawn on a sheet attached to each of the surfaces m1 and m2.

[0058] (Installation part) As shown in FIGS. 1 and 2, the island facility 10 includes an installation portion 60 on which the gaming machine frame 40 is installed. The installation portion 60 has an upper support portion 61 disposed above the gaming machine frame 40 and a lower support portion 62 disposed below the gaming machine frame 40. The upper support portion 61 is a plate-like portion extending along the width direction Dw. The upper support portion 61 is a so-called "ridge board" or "ridge plate". The lower support portion 62 is a plate-like portion extending along the width direction Dw. The lower support portion 62 is a so-called "tray board". The lower surface 61a of the upper support portion 61 faces the upper surface 62a of the lower support portion 62 in the height direction Dh with the space S3 therebetween. The island facility 10 includes a plurality of island columns 11 arranged at predetermined intervals along the width direction Dw. The support portions 61 and 62 are supported so as to span the plurality of island columns 11. The upper support portion 61 is an example of a first support portion. The lower support portion 62 is an example of a second support portion. The gaming machine frame 40 is installed between the upper support portion 61 and the lower support portion 62. A unit frame 50 is also installed in the installation portion 60.

[0059] The separation distance between the lower surface 61a and the upper surface 62a along the height direction Dh is the height dimension Lh of the space S3. The height dimension Lh of the space S3 is slightly larger than the height dimension H1 of the gaming machine frame 40. The gaming machine frame 40 can be accommodated in the space S3 in a state where the gaming machine 20P or the gaming machine 20S is accommodated. The gaming machine frame 40 is placed on the upper surface 62a of the lower support portion 62. That is, the upper surface 62a serves as a support surface for supporting the gaming machine frame 40. The gaming machine frame 40 is fixed to the lower support portion 62 using the lower fixing mechanism 62b. The gaming machine frame 40 is fixed to the upper support portion 61 using the upper fixing mechanism 61b. As an example, each of the fixing mechanisms 61b, 62b may be constituted by a bolt and a nut. Each of the fixing mechanisms 61b, 62b may be configured to include a nut disposed on one of the support portions 61, 62 and a bolt disposed on the gaming machine frame 40. The upper fixing mechanism 61b may be configured to include a nut disposed on the upper support portion 61 and a bolt disposed on the gaming machine frame 40. The lower fixing mechanism 62b may be configured to include a nut disposed on the lower support portion 62 and a bolt disposed on the gaming machine frame 40. The upper fixing mechanism 61b is an example of a first fixing mechanism capable of fixing the first support portion and the housed component. The lower fixing mechanism 62b is an example of a second fixing mechanism capable of fixing the second support portion and the housed component. Each of the fixing mechanisms 61b, 62b may be a clamp, or may be a screw or a nail.

[0060] As shown in FIGS. 3 and 4, the separation distance along the height direction Dh between the installation surface G and the upper surface 62a of the lower support portion 62 is the support surface height 60h. The separation distance along the height direction Dh between the outer surface 44a of the second base portion 44 and the surface 45b of the third base portion 45 is the first adjustment height Hp. The recommended height HP of the gaming machine 20P, the support surface height 60h, and the first adjustment height Hp are such that the dimensions of each part of the island facility 10 are determined so as to satisfy the relational expression of "HP = 60h + Hp". The separation distance along the height direction Dh between the outer surface 43a and the inner surface 43b of the first base portion 43 is the thickness of the first base portion 43, which is the second adjustment height Hs. The recommended height HS of the gaming machine 20S, the support surface height 60h, and the second adjustment height Hs are such that the dimensions of each part of the island facility 10 are determined so as to satisfy the relational expression of "HS = 60h + Hs".

[0061] As shown in FIGS. 5 and 6, the separation distance along the height direction Dh between the outer surface 54a of the second base 54 and the surface 55b of the third base 55 is the first adjustment height Un. The recommended height HN in the management unit 30N, the support surface height 60h, and the first adjustment height Un are such that the dimensions of each part of the island facility 10 are determined to satisfy the relational expression of "HN = 60h + Un". The separation distance along the height direction Dh between the outer surface 53a and the inner surface 53b of the first base 53 is the thickness of the first base 53, which is the second adjustment height Uw. The recommended height HW in the management unit 30W, the support surface height 60h, and the second adjustment height Uw are such that the dimensions of each part of the island facility 10 are determined to satisfy the relational expression of "HW = 60h + Uw". The separation distance along the height direction Dh between the surface 55a and the surface 55b of the third base 55 is the thickness of the third base 55, which is the third adjustment height Uv. The recommended height Hv of the banknote discrimination unit 31, the support surface height 60h, the second adjustment height Uw, the height dimension UH of the unit frame 50, and the third adjustment height Uv are such that the dimensions of each part of the island facility 10 are determined to satisfy the relational expression of "Hv = 60h + Uw + UH + Uv".

[0062] (Conventional island facility) FIGS. 7 and 8 show a conventional island facility 10 with the gaming machine 20P installed. The conventional island facility 10 does not include the gaming machine frame 40 and the unit frame 50. The conventional island facility 10 includes a plurality of island columns 11 arranged at predetermined intervals along the width direction Dw. The conventional island facility 10 includes a top plate 66 and a waist plate 67. The top plate 66 and the waist plate 67 are plate-like members extending along the width direction Dw. The top plate 66 and the waist plate 67 are respectively supported so as to span a plurality of island columns 11. The upper surface 67a of the waist plate 67 is a surface on which the gaming machine 20P is placed and which supports the gaming machine 20P. The conventional island facility 10 may include a supply trough 68 for supplying a gaming medium (for example, gaming balls) to the gaming machine 20P. The conventional island facility 10 may include a recovery trough 69 for recovering the gaming medium (for example, gaming balls) discharged from the gaming machine 20P. The refurbished gaming balls may be lifted by a lifting device (not shown) and supplied again to each gaming machine 20P from the supply trough 68.

[0063] The separation distance along the height direction Dh between the installation surface G and the upper surface 67a becomes the support surface height 60h. In the conventional island facility 10, the dimensions of each part are determined so that the support surface height 60h coincides with the recommended height HP of the gaming machine 20P. In the conventional island facility 10, the gaming machine 20P is installed by fixing the installation frame of the frame W to the cap plate 66 and the side plate 67 using fixing members. As an example, the fixing members are nails and screws, etc. In the conventional island facility 10, the management unit 30N is installed by fixing it to the cap plate 66 and the side plate 67 using fixing members.

[0064] In the conventional island facility 10, when attempting to install the gaming machine 20S, the dimensions of each part are determined so that the support surface height 60h coincides with the recommended height HS of the gaming machine 20S. In the conventional island facility 10, the gaming machine 20S is installed by fixing the housing B to the cap plate 66 and the side plate 67 using fixing members. In the conventional island facility 10, the management unit 30W is installed by fixing it to the cap plate 66 and the side plate 67 using fixing members. The banknote discrimination unit 31 is disposed above the management unit 30W by fixing it to the cap plate 66 using fixing members. The conventional island facility 10 includes a banknote transport unit 32. The banknote transport section 32b of the banknote transport unit 32 is installed so as to connect from one end to the other end of the island facility 10 in the width direction Dw. The banknote transport section 32b is installed by fixing it to a support member spanning a plurality of island columns 11 using fixing members.

[0065] In the conventional island facility 10, when it is desired to replace the gaming machine 20P and the gaming machine 20S, it is necessary to change the installation height of the waist plate 67 in accordance with the recommended height of each gaming machine 20. The space S3 is an example of a space for accommodating the gaming machine 20P or the gaming machine 20S. The hat plate 66 is an example of the first support portion in the conventional island facility 10, and the waist plate 67 is an example of the second support portion in the conventional island facility 10. The hat plate 66 and the waist plate 67 are portions arranged so as to sandwich the space S3. In this specific example, the bill acceptor 32a and the bill transport unit 32b are disposed at a height and position capable of receiving bills from the bill discharge port Nc of the management unit 30N provided in the gaming machine 20P.

[0066] (Installation method of gaming machine frame and unit frame) The installation method of the gaming machine frame 40 will be described together with its operation. As shown in FIG. 9, the gaming machine 20 is removed from the conventional island facility 10 (step S110). For example, the gaming machine 20P can be removed from the island facility 10 by removing the fixing members that fix the frame W and the hat plate 66, and the fixing members that fix the frame W and the waist plate 67. For example, the gaming machine 20S can be removed from the island facility 10 by removing the fixing members that fix the housing B and the hat plate 66, and the fixing members that fix the housing B and the waist plate 67. The bill transport unit 32 is left in the installed state without being removed from the conventional island facility 10.

[0067] Remove the lumbar plate 67 from the island facility 10 (step S120). Next, attach the lower support portion 62 to the island facility 10 (step S130). That is, the lumbar plate 67 and the lower support portion 62 are exchanged. At this time, the lower support portion 62 is fixed so that the height of its upper surface 62a becomes a predetermined support surface height 60h and is spanned over a plurality of island columns 11. The support surface height 60h is lower than the recommended height HP of the gaming machine 20P. Therefore, in step S130, the space S3 is expanded as compared with the conventional island facility 10. Steps S120 and S130 are an example of steps for expanding the space S3 by moving or exchanging at least one of the first support portion and the second support portion. As an example, nuts are embedded in advance in the upper surface 62a of the lower support portion 62.

[0068] Embed a nut in the lower surface 66a of the upper support portion 61 (step S140). In the present embodiment, the cap plate 66 provided in the conventional island facility 10 is directly reused as the upper support portion 61. However, the present invention is not limited to this, and the cap plate 66 may be removed and the upper support portion 61 may be fixed so as to be spanned over a plurality of island columns 11. In this case, nuts may be embedded in the lower surface 61a of the upper support portion 61.

[0076] (Method for replacing the management unit) First, the management unit 30 is removed from the unit frame 50. When installing a management unit 30 having the same width dimension as the removed management unit 30, the new management unit 30 is attached to the unit frame 50. Thereafter, the work is completed. On the other hand, when attaching a management unit 30 having a width dimension different from that of the removed management unit 30, the posture of the unit frame 50 may be selected according to the management unit 30 to be newly attached. When attempting to attach the management unit 30N, the unit frame 50 may be refixed in the posture p1. At this time, the first surface m1 with a predetermined decoration is arranged on the player side. When attempting to attach the management unit 30W, the unit frame 50 may be refixed in the posture p2. At this time, the second surface m2 with a predetermined decoration is arranged on the player side.

[0077] The management unit 30 is attached to the unit frame 50. When attaching the management unit 30N, the top plate of the housing 30B is fixed to the first base 53 of the unit frame 50. The bottom plate of the housing 30B is fixed to the third base 55 of the unit frame 50. When attaching the management unit 30W, the top plate of the housing 30B is fixed to the third base 55 of the unit frame 50.

When attaching the banknote discrimination unit 31, the top plate of the housing 31B is fixed to the second base 54 of the unit frame 50. The bottom plate of the housing 31B is fixed to the third base 55 of the unit frame 50. Thereafter, predetermined wiring is performed and the work is completed.

[0078] The effects of this embodiment will be described. (1) The management unit 30N with a relatively small width dimension can be accommodated in the space s1a, and the management unit 30W with a relatively large width dimension can be accommodated in the space s1b. Thus, in the island facility 10, regardless of which management unit 30 with different width dimensions is installed, it can be installed without modifying the holding part capable of holding external devices. Further, in the island facility 10, in addition to accommodating the management unit 30, the banknote discrimination unit 31 can be accommodated in the space s2. Therefore, an installation method corresponding to the width dimension of the management unit 30 to be installed can be adopted, and the management unit 30 and the banknote discrimination unit 31 can be easily installed.

[0079] (2) In a plurality of banknote discrimination units 31 in a predetermined game parlor, the positions where banknotes are inserted can be unified. Thus, the banknote discrimination unit 31 can be installed neatly and easily.

[0080] (3) By simply inverting the unit frame 50 along the depth direction Dd, an installation method corresponding to the width dimension of the management unit 30 can be adopted. And in the island facility 10, regardless of whether the management unit 30N or the management unit 30W is installed, the banknote discrimination unit 31 can be installed. Thus, the management unit 30N and the management unit 30W can be easily installed without modifying the holding part capable of holding external devices.

[0081] (4) The height of the space s2 capable of accommodating the banknote discrimination unit 31 is a height corresponding to the banknote conveyance path. For this reason, in the island facility 10, a plurality of banknotes inserted into the plurality of banknote discrimination units 31 can be conveyed by one banknote conveyance path.

[0082] (5) Since there are protruding portions 56, 57 that protrude from the side walls 51, 52 toward the other side wall, the minimum separation distance in the width direction Dw in the space s1a is shorter than the minimum separation distance in the width direction Dw in the space s1b. Therefore, even when the management unit 30N is housed in the space s1a, due to the presence of the protruding portions 56, 57, each side wall and the management unit 30N are close to each other, so that the gap that may occur between the management unit 30N and the side wall can be filled. For this reason, no matter which management unit 30 is installed, it can be installed neatly without modifying the unit frame 50.

[0083] (6) At least a part of the bill conveyance path can be visually recognized through the opening of the gaming machine frame 40. Thereby, it is possible to facilitate inspection of the bill conveyance path and the like. (7) In the state where the gaming machine 20P is installed, when the mounting frame is opened, at least a part of the bill conveyance path is visible. On the other hand, in the state where the gaming machine 20S is installed, even when the front door is opened, the bill conveyance path is not visible or is difficult to see due to the rear wall of the housing B. However, in the island facility 10, even if the gaming machine 20S in which the bill conveyance path cannot be visually recognized even when the front door is opened is installed, at least a part of the bill conveyance path is configured to be visible through the opening of the gaming machine frame 40. Thereby, it is possible to facilitate inspection of the bill conveyance path and the like regardless of whether the gaming machine 20P or the gaming machine 20S is installed.

[0084] (8) The height of the opening of the gaming machine frame 40 is a height corresponding to the bill conveyance path. For this reason, it is possible to facilitate inspection of the bill conveyance path from the opening. (9) By moving or replacing at least one of the cap plate 66 and the waist plate 67, the space S3 for accommodating the gaming machine 20 can be expanded. And in the expanded space S3, a gaming machine frame 40 capable of accommodating the gaming machine 20 can be installed. Therefore, the gaming machine 20 can be made replaceable.

[0085] (10) In accordance with the gaming machine 20 to be set, the gaming machine frame 40 is set in the posture P1 or the posture P2. Therefore, among the gaming machines 20P and 20S, the target gaming machine 20 can be easily set.

[0086] (11) Since the fixing mechanisms 61b and 62b are provided, the gaming machine frame 40 can be fixed, making it easier to perform the replacement work of the gaming machine 20. (12) Since the fixing mechanisms 61b and 62b are constituted including nuts and bolts, the gaming machine frame 40 can be fixed with a simple configuration.

[0087] (13) Whether the gaming machine frame 40 is to be set in the posture P1 or the posture P2, the upper fixing mechanism 61b and the lower fixing mechanism 62b can be used. Therefore, every time the installation mode of the gaming machine frame 40 is changed, there is no need to modify the mechanism for fixing the gaming machine frame 40 to the island facility 10. Therefore, in accordance with the type of the gaming machine 20, the installation mode of the gaming machine frame 40 can be easily changed. Therefore, the gaming machine 20 can be made replaceable.

[0088] (14) The recommended height when installing the gaming machine 20 varies depending on the type of the gaming machine 20. For example, Patent Document (Japanese Unexamined Patent Application Publication No. 2015 - 228981) discloses an island facility whose height for installing the gaming machine 20 is adjustable. However, it is expected to more easily adjust the installation height of the gaming machine 20. The island facility 10 of the present embodiment can adjust the height of the mounting surfaces (surfaces 43b and 45b) of the gaming machine 20 on the gaming machine frame 40 to the recommended height only by turning the gaming machine frame 40 upside down. Therefore, the type of the gaming machine 20 can be easily changed.

[0089] (15) The gaming machine 20S has a smaller width dimension than the gaming machine 20P. The gaming machine frame 40 is provided with protruding portions 46 and 47 that protrude into the space S1. Therefore, even when the gaming machine 20S is installed with the gaming machine frame 40 in the posture P2, it is difficult for gaps to occur on the left and right sides of the gaming machine 20S. Therefore, the gaming machine can be installed in a good-looking manner.

[0090] When the gaming machine frame 40 is in the posture P2, the protruding portions 46 and 47 are arranged along the edge on the player side (the second surface M2 side) in the depth direction Dd. Therefore, the unevenness on the second surface M2 of the gaming machine frame 40 can be reduced, and the aesthetic appearance can be improved.

[0091] (17) Generally, the island equipment is decorated for the purpose of improving the aesthetic appearance of the game arcade. For example, a sheet with a pattern printed thereon is attached to the island equipment. For example, a pattern is drawn on the island equipment using paint. However, in the conventional island equipment, changing the decoration requires high technology. For this reason, it has been difficult to change the decoration of the conventional island equipment. In contrast, in the island equipment 10, different decorations are applied to the respective surfaces M1 and M2 of the gaming machine frame 40 in the depth direction Dd. Therefore, by changing the posture of the gaming machine frame 40, the decoration of the island equipment 10 can be easily changed.

[0092] (18) When the unit frame 50 is in the posture p1, the protruding portions 56 and 57 are arranged along the edge on the player side (the first surface m1 side) in the depth direction Dd. Therefore, the unevenness on the first surface m1 of the unit frame 50 can be reduced, and the aesthetic appearance can be improved.
