As will be described later, the island equipment 10 is configured to allow for the replacement of gaming machines 20P and gaming machines 20S.

[0009] In the island facility 10, multiple gaming machines 20 are installed so as to be aligned along the width direction Dw, which is an example of a predetermined direction. The direction perpendicular to the height direction Dh and the width direction Dw is referred to as the depth direction Dd. For example, the width direction Dw and the depth direction Dd may coincide with the horizontal direction. For example, the height direction Dh may coincide with the vertical direction. In the following description, the dimensions (lengths) along the width direction Dw, the height direction Dh, and the depth direction Dd are simply referred to as the width dimension, height dimension, and depth dimension, respectively.

[0010] In the island facility 10, each gaming machine 20 is equipped with a management unit 30, which is an example of an external device. Each gaming machine 20 is connected to the management unit 30 so that they can communicate with each other. The management unit 30 may be connected to a hall computer installed in the office of the gaming parlor or elsewhere. The management unit 30 may be connected to a server device installed in a designated data center via an internet or other telecommunication line.

[0011] In the island equipment 10, the management unit 30 may be equipped with an external device, such as a banknote identification unit 31. The banknote identification unit 31 may also be equipped with the gaming machine 20. The banknote identification unit 31 is a device into which players insert banknotes. The management unit 30 is connected to the banknote identification unit 31 for communication purposes.

[0012] The island equipment 10 includes a banknote transport unit 32 capable of transporting banknotes. The banknote transport unit 32 is located inside the island equipment 10. The banknote transport unit 32 is capable of receiving banknotes inserted into the management unit 30. The banknote transport unit 32 is capable of receiving banknotes inserted into the banknote identification unit 31. The banknote transport unit 32 is capable of transporting banknotes received from the management unit 30 or the banknote identification unit 31.

[0013] (Pachinko gaming machine) As shown in Figures 1 to 3, the gaming machine 20P is a sealed-type gaming machine. In gaming machine 20P, game balls, which are an example of a game medium, are circulated inside the machine. Gaming machine 20P does not require a supply of game balls from the island equipment 10. Gaming machine 20P does not require the return (discharge) of game balls to the island equipment 10.

[0014] The gaming machine 20P has a frame W, a game board YB, various operation devices, a display device DS, and a control device CU. The frame W includes a fixed frame KW fixed to the island facility 10 and a mounting frame on which the game board YB, various operation devices, the display device DS, and the control device CU are mounted. The fixed frame KW is in the shape of a rectangular frame having openings on both sides in the depth direction Dd. The mounting frame is pivotally supported on the left edge of the fixed frame KW. The mounting frame is openable and closable so as to rotate around an axis. The mounting frame is an example of a door portion that can be opened and closed with respect to the fixed frame KW. 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 opened 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 width dimension of the control device CU are smaller than the height dimension Ph and 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 held balls. 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. The gaming machine 20S can conduct games using electronically processed gaming media. The gaming machine 20S does not require replenishment of gaming medals from the island equipment 10 or the like. 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 cabinet B, a front door, a plurality of reels, various operation devices, and a control device. The cabinet B is in the shape of a rectangular box having an opening on the player side in the depth direction Dd. That is, the cabinet B has a rear wall on the side opposite to the player side in the depth direction Dd. The rear side of the cabinet B is sealed by the rear wall. The cabinet B is an example of a main box fixed to the island equipment 10. The front door is pivotally supported at the left edge of the opening in the cabinet B. The front door can open and close the opening of the cabinet 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 cabinet 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 cabinet B.

[0020] The control unit's processor manages the number of game tokens a2, which represent the player's holdings. The control unit's processor increases the number of bets in response to the operation of the bet button. The processor subtracts the number of game tokens a2 in accordance with the increase in the number of bets. The processor rotates the reels in response to the operation of the start lever, thus starting the variable game. The processor stops the reels in response to the operation of the stop button. When all reels have stopped and a specific combination of symbols is displayed, the processor adds a number corresponding to that combination of symbols to the number of game tokens a2.

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

[0022] (Recommended height when installing gaming machines) In the island equipment 10, the recommended installation height (hereinafter referred to as the recommended height) for the gaming machine 20 varies depending on the type of gaming machine 20. The recommended height for the gaming machine 20 is set to a height that makes it easy for players to operate the various operating devices installed on the gaming machine 20 while seated in a chair. For example, the recommended height HS for gaming machine 20S is lower than the recommended height HP for gaming machine 20P. The recommended height HS for gaming machine 20S is preferably 450mm to 550mm, more preferably 490mm to 510mm, and even more preferably 500mm, from the installation surface G of the island equipment 10 to the bottom surface of the gaming machine 20S. The recommended height HP for gaming machine 20P is preferably 600mm to 700mm, more preferably 640mm to 660mm, and even more preferably 651mm, from the installation surface G of the island equipment 10 to the bottom surface of the gaming machine 20P.

[0023] (Management Unit) As shown in Figures 1, 5, and 6, the management unit 30 includes a housing 30B. The housing 30B is a rectangular box formed by bending a steel plate or the like. The management unit 30 has an insertion slot 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 money inserted and the number of game mediums a1 held by the player. The management unit 30 has a payout operation unit as an example of an operating device. When a game medium payout operation is performed using the payout operation unit, the management unit 30 transmits payout information to the game machine 20. When the management unit 30 receives the counting information, it adds the number of transfers that can be identified from the counting information to the number of game mediums a1 stored in the management medium.

[0024] For example, the management unit 30 includes management unit 30N and management unit 30W. Management unit 30N and management unit 30W are examples of first external devices. Management unit 30N is an example of first type first external device. Management unit 30W is an example of second type first external device. For example, management unit 30N has a banknote slot Na on the player side (front side) of the housing 30B. For example, management unit 30N incorporates a banknote identifier 30Nb. The banknote identifier 30Nb identifies the type and authenticity of banknotes inserted through the banknote slot Na. If the banknote identifier 30Nb determines that a banknote is counterfeit, or if it cannot identify it, it returns the inserted banknote through the banknote slot Na. For example, management unit 30N has a banknote outlet Nc on the opposite side (rear side) of the housing 30B from the player side. If the banknote identification machine 30Nb determines that the inserted banknote is not counterfeit, it ejects the inserted banknote from the banknote output slot Nc. When a banknote is inserted, the management unit 30N adds it to the balance stored in the management medium.

[0025] For example, the management unit 30W does not have a banknote slot. For example, the management unit 30W does not have a built-in banknote identifier. For example, the management unit 30W is connected to the banknote identifier unit 31. When the management unit 30W receives information on the amount inserted from the banknote identifier 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 the game medium is dispensed using the dispensing operation unit, the management unit 30W transmits the dispensing information to the game machine 20.

[0026] The height dimension Nh of the control unit 30N and the height dimension Wh of the control unit 30W are the same or approximately the same. The width dimension Ww of the control unit 30W is larger than the width dimension Nw of the control unit 30N. In other words, the length of the control unit 30W along the width direction Dw is longer than that of the control unit 30N. For example, the width dimension Nw of the control unit 30N may be 40 mm, and the width dimension Ww of the control unit 30W may be 100 mm. The height dimension Nh of the control unit 30N is the same or approximately 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 control unit 30W is the same or approximately the same as the height dimension Ph of the gaming machine 20P and the height dimension Sh of the gaming machine 20S.

[0027] (Banknote identification unit) As shown in Figures 1 and 5, the banknote identification unit 31 includes a housing 31B. The housing 31B is a rectangular box formed by bending a steel plate or the like. The banknote identification unit 31 has a banknote slot 31N that opens on the player side (front side) of the housing 31B. The banknote identification unit 31 is an example of a second external device. The banknote identification unit 31 is an example of a banknote identification machine. If the banknote identification unit 31 determines that a banknote is counterfeit, or if it cannot identify it, it returns the inserted banknote from the banknote slot 31N. The banknote identification unit 31 has a banknote outlet 31M that opens on the opposite side (rear side) of the housing 31B from the player side. If the banknote identification unit 31 determines that a banknote is not counterfeit, it discharges the inserted banknote from the banknote outlet 31M. If the banknote identification unit 31 determines that the banknote is not counterfeit, it transmits information about the amount of the inserted banknote to the management unit 30, which allows it to identify the value of the inserted banknote.

[0028] (Banknote transport unit) As shown in Figures 1, 2, 5, and 6, the banknote transport unit 32 has a banknote transport section 32b that transports banknotes received from each banknote receiving section 32a in a predetermined direction. The banknote transport section 32b is a rectangular rail member that extends along the width direction Dw. The banknote transport section 32b is installed to connect one end of the island equipment 10 to the other end in the width direction Dw. A banknote transport path is formed in the banknote transport section 32b for transporting banknotes. The banknote transport section 32b transports banknotes received from the banknote receiving section 32a in the width direction Dw (for example, to the right). For example, the banknote transport section 32b transports banknotes by controlling the airflow in the banknote transport path. However, the banknote transport section 32b may also be equipped with a transport belt, and banknotes may be transported by controlling the transport belt. As an example, banknotes transported by the banknote transport unit 32b are stored in a safe located at the end of the island equipment 10 in the width direction Dw.

[0029] The banknote transport unit 32 has multiple banknote receiving sections 32a. The multiple banknote receiving sections 32a are installed on the opposite side (rear side) from the player side of the management units 30N, 30W and the banknote identification unit 31, respectively, so as to correspond to either the banknote discharge port Nc of the management unit 30N or the banknote discharge port 31M of the banknote identification unit 31. Since each banknote receiving section 32a has the same configuration, one of them will be described in detail.

[0030] The banknote receiving section 32a has a banknote receiving opening 32c on the player side (front side) in the depth direction Dd. The width dimension of the banknote receiving opening 32c is the same as or approximately the same as the width dimension of the banknote dispensing opening Nc. The height dimension of the banknote receiving opening 32c is the same as or approximately the same as the height dimension of the banknote dispensing opening Nc. The banknote receiving opening 32c faces the banknote dispensing opening Nc in the depth direction Dd so that it can receive banknotes dispensed from the banknote dispensing opening Nc. Assuming a perspective view from the front, the banknote receiving opening 32c is positioned so that it partially or completely overlaps with the banknote dispensing opening Nc. The width dimension of the banknote receiving opening 32c is the same as or approximately the same as the width dimension of the banknote dispensing opening 31M. The height dimension of the banknote receiving opening 32c is the same as or approximately the same as the height dimension of the banknote dispensing opening 31M. The banknote receiving slot 32c faces the banknote dispensing slot 31M in the depth direction Dd so that it can receive banknotes dispensed from the banknote dispensing slot 31M. Assuming a perspective view from the front, the banknote receiving slot 32c is positioned so that it partially or completely overlaps with the banknote dispensing slot 31M.

[0031] (Recommended height when installing the control unit) In the island equipment 10, the recommended height of the management unit 30 varies depending on the type of gaming machine 20 to which it is connected. The recommended height of the management unit 30 is set to a height that makes it easy for a player to operate the various operating devices installed on the management unit 30 while seated in a chair. The recommended height of the management unit 30 is set to a height that makes it easy to insert banknotes into the banknote slot Na. For example, the recommended height HN of management unit 30N is the same as the recommended height HP of gaming machine 20P. For example, the recommended height HW of management unit 30W is the same as the recommended height HS of gaming machine 20S. Note that the recommended height HN of management unit 30N may be the same as or different from the recommended height HW of management unit 30W.

[0032] (Recommended height when installing the banknote identification unit) In the island equipment 10, the recommended height Hv of the banknote identification unit 31 is set to a height corresponding to the position of the banknote receiving port 32c of the banknote transport unit 32. Assuming a view from the front, the recommended height Hv of the banknote identification unit 31 is set to a height where all or almost all of the banknote receiving port 32c and the banknote dispensing port 31M overlap each other. However, assuming a view from the front, the recommended height Hv of the banknote identification unit 31 may be set to a height where part of the banknote receiving port 32c and the banknote dispensing port 31M overlap each other. In other words, the recommended height Hv of the banknote identification unit 31 is set to a height that allows the banknote receiving port 32c to receive banknotes discharged from the banknote dispensing port 31M. For example, the recommended height Hv of the banknote identification unit 31 may be set to a height where banknotes discharged from the banknote dispensing port 31M are received horizontally or almost horizontally into the banknote receiving port 32c in the depth direction Dd. Furthermore, the recommended height HN of the management unit 30N can be said to be set to a height that allows the banknote receiving port 32c to accept banknotes discharged from the banknote discharge port Nc.

[0033] (Gaming machine frame) The island equipment 10 comprises multiple gaming machine frames 40, each capable of holding a gaming machine 20. Each gaming machine frame 40 is an example of a gaming machine holder capable of holding a predetermined number of gaming machines 20. For example, the predetermined number is 1. In other words, each gaming machine frame 40 can hold one gaming machine 20. Each gaming machine frame 40 is configured to hold either a gaming machine 20P or a gaming machine 20S. That is, in the island equipment 10, each gaming machine frame 40 is installed holding either one gaming machine 20P or one gaming machine 20S. Since each gaming machine frame 40 has the same configuration, we will explain one of them in detail.

[0034] As shown in Figures 1, 2, 3(a) to 3(c), and 4(a) to 4(c), the gaming machine frame 40 is a rectangular frame-shaped member extending along the height direction Dh. The gaming machine frame 40 is open at both ends in the depth direction Dd. The gaming machine frame 40 is installed in posture P1 or posture P2. Posture P1 is the posture in which the end E1 of the gaming machine frame 40 in the height direction Dh is positioned upwards and the opposite end E2 is positioned downwards.

[0037] The gaming machine frame 40 comprises a first base portion 43 and a second base portion 44 as parts that constitute the ceiling or bottom of the gaming machine frame 40. The base portions 43 and 44 are flat, plate-shaped portions that extend along the width direction Dw. The base portions 43 and 44 extend parallel or substantially parallel to each other. The first base portion 43 is connected at the end E1 of the gaming machine frame 40 so as to connect the ends of the side walls 41 and 42. The first base portion 43 can also be said to constitute the end E1 of the gaming machine frame 40. The second base portion 44 is connected at the end E2 of the gaming machine frame 40 so as to connect the ends of the side walls 41 and 42. The second base portion 44 can also be said to constitute the end E2 of the gaming machine frame 40. The base portions 43 and 44 face each other across a space S from the height direction Dh. A predetermined number (two, for example) of bolt holes are formed in each of the base portions 43 and 44.

[0038] The gaming machine frame 40 includes a third base portion 45 connected between the base portions 43 and 44, connecting the side walls 41 and 42. The third base portion 45 is a flat, plate-like portion extending along the width direction Dw. The third base portion 45 extends parallel or substantially parallel to the base portions 43 and 44. The directions in which the base portions 43 to 45 extend and the directions in which the side walls 41 and 42 extend intersect, and more preferably are perpendicular to each other. The third base portion 45 divides the space S enclosed by the side walls 41 and 42 and the base portions 43 and 44 in the height direction Dh, forming space S1 and space S2. As will be described later, space S1 is a space for housing the gaming machines 20P and 20S. Space S2 connects the inside and outside of the island equipment 10 and is a space for maintenance and inspection of the inside of the island equipment 10. The inner surface 43b of the first base 43 and the surface 45b of the third base 45 face each other across space S1.

[0039] The gaming machine frame 40 includes a first projection 46 that protrudes into space S from the inner surface 41b of the first side wall 41.

The projections 46 and 47 are provided on the edges of the side walls 41 and 42 on the second surface M2 side, respectively. The projections 46 and 47 are prismatic portions that extend along the height direction Dh. The projections 46 and 47 are provided from the inner surface 43b of the first base 43 to the surface 45b of the third base 45. In other words, the projections 46 and 47 extend from the upper end to the lower end of space S1. The projections 46 and 47 face each other across space S1 from the width direction Dw. The inner surface 46b of the first protrusion 46 and the inner surface 47b of the second protrusion 47 face each other across space S1. The portion of space S1 sandwiched between the inner surface 46b of the first protrusion 46 and the inner surface 47b of the second protrusion 47 is space S1a. The portion of space S1 excluding space S1a is space S1b.

[0040] The gaming machine frame 40 is equipped with an inspection door Dr configured to seal off all or substantially all of the space S2 when viewed from the front. The inspection door Dr is a plate-shaped member. The inspection door Dr is configured to open and close so as to rotate around an axis provided on one of the walls surrounding the space S2. The inspection door Dr may be equipped with a locking mechanism so as to prevent it from being opened or closed without a key. The inspection door Dr may be formed by combining multiple door members. In this way, the inspection door Dr can open and close the opening of the gaming machine frame 40.

[0041] The height dimension H1 of the gaming machine frame 40 is greater than the width dimension H2 of the gaming machine frame 40. The distance between the inner surface 41b of the first side wall 41 and the inner surface 42b of the second side wall 42 along the width direction Dw is the width dimension Hwb of space S1b. The width dimension Hwb of space S1b is slightly greater than the width dimension Pw of the gaming machine 20P. The distance between the inner surface 46b of the first protrusion 46 and the inner surface 47b of the second protrusion 47 along the width direction Dw is the width dimension Hwa of space S1a. The width dimension Hwa of space S1a is smaller than the width dimension Pw of the gaming machine 20P and smaller than the width dimension Hwb of space S1b. However, the width dimension Hwa is larger than the width dimension of the part of the gaming machine 20P that protrudes to the rear (control device CU). The distance between the inner surface 43b of the first base 43 and the surface 45b of the third base 45 along the height direction Dh is the height dimension Hh of space S1. The height dimension Hh of space S1 is slightly larger than the height dimension Ph of the gaming machine 20P. Therefore, 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. 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 space S1b is greater than the width dimension Sw of the gaming machine 20S. The width dimension Hwa of space S1a is slightly greater than the width dimension Sw of the gaming machine 20S, but smaller than the width dimension Pw of the gaming machine 20P. The height dimension Hh of space S1 is slightly greater than the height dimension Sh of the gaming machine 20S. Therefore, spaces S1a and S1b have a shape that corresponds to the external 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 section on which the gaming machine 20 can be installed, provided by the side walls 41, 42, protrusions 46, 47, and bases 43, 45, and the installation section 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 section. The gaming machine 20S is installed by fixing the housing B to the installation section.

[0043] When the gaming machine frame 40 is installed in orientation 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 32bb of the banknote transport section 32b. When the gaming machine frame 40 is installed in orientation 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 equipment 10 to the upper end 32ba of the banknote transport section 32b. Therefore, when the inspection door Dr is opened while the gaming machine frame 40 is installed in orientation P2, the space S2 connects the inside and outside of the island equipment 10, and at least a portion of the banknote transport section 32b (banknote transport path) can be seen from the front. Thus, the height of the space S2 is said to be the height corresponding to the banknote transport section 32b. In this way, the gaming machine frame 40 has an opening that allows at least a portion of the banknote transport section 32b located inside the island equipment 10 to be seen.

[0044] The first surface M1 is composed of one of the end faces of the side walls 41, 42 and the base 43-45 in the depth direction Dd. The first surface M1 is composed of one of the two faces of the inspection door Dr in the depth direction Dd. The second surface M2 is composed of the other end face of the side walls 41, 42 and the base 43-45 in the depth direction Dd. The second surface M2 is composed of the other face of the two faces 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 differently from each other. For example, the decoration may be characters, landscapes, patterns, and letters drawn on each surface M1 and M2 using paint or the like. The decoration may be characters, landscapes, patterns, and letters drawn on sheets attached to each surface M1 and M2.

[0045] (Unit slot) The island equipment 10 comprises a plurality of unit frames 50, each capable of holding a management unit 30 and a banknote identification unit 31. Each unit frame 50 is capable of holding a specified number of management units 30 and a specified number of banknote identification units 31. The unit frame 50 is an example of a holding section for the management unit 30 that can hold multiple types of external devices. For example, the specified number is 1. In other words, each unit frame 50 is capable of holding one management unit 30 and one banknote identification unit 31. Each unit frame 50 is configured to hold either a management unit 30N or a management unit 30W. In other words, in the island equipment 10, each unit frame 50 can be installed holding one management unit 30N or one management unit 30W and one banknote identification unit 31. Since each unit frame 50 has the same configuration, one of them will be described in detail.

[0046] As shown in Figures 1, 2, 5(a) to 5(c), and 6(a) to 6(c), the unit frame 50 is a rectangular frame-shaped 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 posture p1 or posture p2. Posture p1 is the posture in which the end e1 of the unit frame 50 in the height direction Dh is positioned upwards and the opposite end e2 is positioned downwards. Posture p1 is the posture in which the first surface m1 of the unit frame 50 in the depth direction Dd is positioned towards the player and the opposite second surface m2 is positioned inside the island equipment 10. Posture p2 is the posture in which the end e2 of the unit frame 50 is positioned upwards and the end e1 is positioned downwards. Posture p2 is the posture in which the second surface m2 is positioned towards the player and the first surface m1 is positioned inside the island equipment 10. The first surface m1, which is the end of the unit frame 50 in the depth direction Dd, is an example of the first end. The second surface m2, which is the end of the unit frame 50 in the depth direction Dd, is an example of the second end. Thus, there are two installation modes for the unit frame 50: a first mode (position p1) in which the first surface m1 of the unit frame 50 is positioned towards the player, and a second mode (position p2) in which the second surface m2, which is opposite to the first surface m1, is positioned towards the player.

[0047] The unit frame 50 is an example of a component that can accommodate the management unit 30N and the management unit 30W interchangeably. Orientation p1 is the orientation suitable for installing the management unit 30N. When the unit frame 50 is in orientation p1 and the management unit 30N is held in the island equipment 10, the management unit 30N is installed at the recommended height HN (see Figure 1). Orientation p2 is the orientation suitable for installing the management unit 30W. When the unit frame 50 is in orientation p2 and the management unit 30W is held in the island equipment 10, the management unit 30W is installed at the recommended height HW (see Figure 1).

[0048] The unit frame 50 includes a first side wall 51 and a second side wall 52 as parts that constitute the side walls of the unit frame 50. The side walls 51 and 52 are flat, plate-like parts that extend along the height direction Dh. The side walls 51 and 52 extend parallel or substantially parallel to each other as side walls aligned along the width direction Dw. The side walls 51 and 52 face each other across a space s from 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 across a space s.

[0049] The unit frame 50 comprises a first base portion 53 and a second base portion 54 as parts that constitute the ceiling or bottom of the unit frame 50. The base portions 53 and 54 are flat, plate-like portions that extend along the width direction Dw. The base portions 53 and 54 extend parallel or substantially parallel to each other. The first base portion 53 is connected at 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 portion 53 constitutes end e1 of the unit frame 50. The second base portion 54 is connected at 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 portion 54 constitutes end e2 of the unit frame 50. The base portions 53 and 54 face each other across space s from the height direction Dh.

[0050] The unit frame 50 includes a third base 55 connected between the bases 53 and 54, connecting 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 directions in which the bases 53 to 55 extend and the directions in which the side walls 51 and 52 extend intersect, and more preferably are perpendicular to each other. The third base 55 divides the space s enclosed by the side walls 51 and 52 and the bases 53 and 54 in the height direction Dh, forming space s1 and space s2. As will be described later, space s1 is a space for housing the management units 30N and 30W. Space s2 is a space for housing the banknote identification unit 31. The inner surface 53b of the first base 53 and the surface 55b of the third base 55 face each other across space s1. The inner surface 54b of the second base 54 and the surface 55a of the third base 55 face each other across space s2. Space s2 is an example of a third space.

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

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

[0053] The width dimension Uwb of space s1b is greater than the width dimension Nw of the management unit 30N. The width dimension Uwa of space s1a is slightly greater than the width dimension Nw of the management unit 30N, but smaller than the width dimension Ww of the management unit 30W. The height dimension Uh of space s1 is slightly greater than the height dimension Nh of the management unit 30N. Therefore, spaces s1a and s1b have a shape that corresponds to the external 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. In this way, a space s1a for accommodating the management unit 30N is formed between the first side wall 51 and the second side wall 52 in the unit frame 50. Therefore, in the island facility 10, the management unit 30N can be accommodated in space s1a while the unit frame 50 is installed in orientation p1.

[0054] When the unit frame 50 is installed in orientation p1 and the management unit 30N is installed, the height of the management unit 30N is the recommended height HN. Assuming a view from the front, the recommended height HN of the management unit 30N is the height at which the entire or almost entire banknote receiving slot 32c and the banknote dispensing slot Nc overlap each other. However, it is not limited to this, and assuming a view from the front, the recommended height HN of the management unit 30N may be the height at which the banknote receiving slot 32c and the banknote dispensing slot Nc partially overlap each other. In other words, the recommended height HN of the management unit 30N is the height at which the banknote receiving slot 32c can receive banknotes discharged from the banknote dispensing slot Nc. For example, the recommended height HN of the management unit 30N should be the height at which banknotes discharged from the banknote dispensing slot Nc are received horizontally or almost horizontally into the banknote receiving slot 32c in the depth direction Dd.

[0055] The distance between the inner surface 51b of the first side wall 51 and the inner surface 52b of the second side wall 52 along the width direction Dw is the width dimension Uwb of space s2. Note that the width dimension of space s1b and the width dimension of space s2 may be different or the same. The width dimension Uwb of space s2 is slightly larger than the width dimension Vw of the banknote identification unit 31. The distance between the inner surface 54b of the second base 54 and the surface 55a of the third base 55 along the height direction Dh is the height dimension Ah of space s2. The height dimension Ah of space s2 is slightly larger than the height dimension Vh of the banknote identification unit 31. Therefore, space s2 has a shape corresponding to the outer shape of the banknote identification unit 31 and is large enough to accommodate the banknote identification unit 31. In this way, space s2 for accommodating the banknote identification unit 31 is formed between the first side wall 51 and the second side wall 52 in the unit frame 50. Furthermore, space s2 connects the inside and outside of the island equipment 10. The width dimension Uwb of space s2 is the same or approximately the same dimension from the first surface m1 to the second surface m2. The height dimension Ah of space s2 is the same or approximately the same dimension from the first surface m1 to the second surface m2. Therefore, the banknote identification unit 31 can be accommodated in space s2 regardless of whether the unit frame 50 is installed in orientation p1 or orientation p2.

[0056] When the unit frame 50 is installed in orientation p2 and the banknote identification unit 31 is installed, the height of the banknote identification unit 31 is the recommended height Hv. Assuming a view from the front, the recommended height Hv of the banknote identification unit 31 is the height at which the banknote receiving port 32c and the banknote discharging port Nc all or almost all overlap each other. The recommended height Hv of the banknote identification unit 31 is the height at which the banknote receiving port 32c can receive banknotes discharged from the banknote discharging port 31M. Therefore, the height of space s2 can be said to be the height corresponding to the height of the banknote transport unit 32. Consequently, the height of space s2 can also be said to be the height corresponding to the banknote transport section 32b (banknote transport path).

[0057] The first surface m1 is formed by the side walls 51, 52 and one end face of the base 53-55 in the depth direction Dd. The second surface m2 is formed by the other end face of the side walls 51, 52 and the base 53-55 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. For example, the decoration may be characters, landscapes, patterns, and letters drawn on each surface m1 and m2 using paint or the like. The decoration may be characters, landscapes, patterns, and letters drawn on sheets attached to each surface m1 and m2.

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

[0059] The 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 housed in space S3 with the gaming machine 20P or gaming machine 20S inside. The gaming machine frame 40 is placed on the upper surface 62a of the lower support part 62. In other words, the upper surface 62a becomes the support surface that supports the gaming machine frame 40. The gaming machine frame 40 is fixed to the lower support part 62 using the lower fixing mechanism 62b. The gaming machine frame 40 is fixed to the upper support part 61 using the upper fixing mechanism 61b. For example, each fixing mechanism 61b, 62b may be composed of bolts and nuts. Each fixing mechanism 61b, 62b may include a nut disposed on one of the support parts 61, 62 and a bolt disposed on the gaming machine frame 40. The upper fixing mechanism 61b may include a nut disposed on the upper support part 61 and a bolt disposed on the gaming machine frame 40. The lower fixing mechanism 62b may include a nut disposed on the lower support part 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 part and the housing part. The lower fixing mechanism 62b is an example of a second fixing mechanism capable of fixing the second support part and the housing part. Each fixing mechanism 61b, 62b may be a clamp, a screw, or a nail.

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

[0061] As shown in Figures 5 and 6, the distance between the outer surface 54a of the second base 54 and the surface 55b of the third base 55 along the height direction Dh is the first adjustment height Un. The dimensions of each part of the island equipment 10 are determined so that the recommended height HN in the management unit 30N, the support surface height 60h, and the first adjustment height Un satisfy the relationship "HN = 60h + Un". The distance between the outer surface 53a of the first base 53 and the inner surface 53b of the first base 53 along the height direction Dh is the thickness of the first base 53, and is the second adjustment height Uw. The dimensions of each part of the island equipment 10 are determined so that the recommended height HW in the management unit 30W, the support surface height 60h, and the second adjustment height Uw satisfy the relationship "HW = 60h + Uw". The distance between the surface 55a and the surface 55b of the third base 55 along the height direction Dh is the thickness of the third base 55 and is the third adjustment height Uv. The dimensions of each part of the island equipment 10 are determined such that the recommended height Hv of the banknote identification 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 satisfy the relationship "Hv = 60h + Uw + UH + Uv".

[0062] (Conventional island facilities) Figures 7 and 8 show a conventional island setup 10 with a gaming machine 20P installed. The conventional island setup 10 does not include a gaming machine frame 40 and a unit frame 50. The conventional island setup 10 includes a plurality of island pillars 11 arranged at predetermined intervals along the width direction Dw. The conventional island setup 10 includes a cap plate 66 and a base plate 67. The cap plate 66 and the base plate 67 are plate-shaped members that extend along the width direction Dw. The cap plate 66 and the base plate 67 are each supported so as to span across a plurality of island pillars 11. The upper surface 67a of the base plate 67 is the surface on which the gaming machine 20P is placed and which supports the gaming machine 20P. The conventional island setup 10 may also include a supply trough 68 for supplying a game medium (for example, game balls) to the gaming machine 20P. Conventional island equipment 10 may include a collection trough 69 for collecting game media (game balls, for example) discharged from the game machines 20P. The modified game balls may be lifted by a lifting device (not shown) and supplied again to each game machine 20P from a supply trough 68.

[0063] The distance between the installation surface G and the top surface 67a along the height direction Dh is equal to the support surface height 60h. In conventional island equipment 10, the dimensions of each part are determined so that the support surface height 60h matches the recommended height HP of the gaming machine 20P. In conventional island equipment 10, the gaming machine 20P is installed by fixing the installation frame of the frame W to the cap plate 66 and the lower plate 67 using fixing members. For example, fixing members include nails and screws. In conventional island equipment 10, the management unit 30N is installed by fixing it to the cap plate 66 and the lower plate 67 using fixing members.

[0064] In conventional island equipment 10, when installing a gaming machine 20S, the dimensions of each part are determined so that the support surface height 60h matches the recommended height HS of the gaming machine 20S. In conventional island equipment 10, the gaming machine 20S is installed by fixing the housing B to the canopy plate 66 and the lower plate 67 using fixing members. In conventional island equipment 10, the management unit 30W is installed by fixing it to the canopy plate 66 and the lower plate 67 using fixing members. The banknote identification unit 31 is positioned above the management unit 30W by fixing it to the canopy plate 66 using fixing members. Conventional island equipment 10 includes a banknote transport unit 32. The banknote transport section 32b of the banknote transport unit 32 is installed so as to connect one end to the other end of the island equipment 10 in the width direction Dw. The banknote transport section 32b is installed by fixing it to a support member that spans multiple island columns 11 using fixing members.

[0065] In a conventional island setup 10, when replacing a gaming machine 20P with a gaming machine 20S, it is necessary to change the installation height of the lower panel 67 to match the recommended height of each gaming machine 20. Space S3 is an example of a space for housing a gaming machine 20P or a gaming machine 20S. The cap plate 66 is an example of a first support part in a conventional island setup 10, and the lower panel 67 is an example of a second support part in a conventional island setup 10. The cap plate 66 and the lower panel 67 are parts that are arranged to sandwich space S3. In this specific example, the banknote receiving section 32a and the banknote transport section 32b are arranged at a height and position that allows them to receive banknotes from the banknote discharge port Nc of the management unit 30N attached to the gaming machine 20P.

[0066] (Installation method for gaming machine frames and unit frames) The installation method of the gaming machine frame 40 will be explained along with its function. As shown in Figure 9, the gaming machine 20 is removed from the conventional island equipment 10 (step S110). For example, gaming machine 20P can be removed from the island equipment 10 by removing the fixing members that fix the frame W and the canopy 66, and the fixing members that fix the frame W and the lower panel 67. For example, gaming machine 20S can be removed from the island equipment 10 by removing the fixing members that fix the housing B and the canopy 66, and the fixing members that fix the housing B and the lower panel 67. The banknote transport unit 32 is left installed in the conventional island equipment 10 without being removed.

[0067] Step S120: Remove the lower panel 67 from the island equipment 10. Next, attach the lower support part 62 to the island equipment 10 (Step S130). In other words, the lower panel 67 and the lower support part 62 are swapped. At this time, the lower support part 62 is fixed so that the height of its upper surface 62a is a predetermined support surface height 60h and so that it spans across multiple 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 compared to the conventional island equipment 10. Steps S120 and S130 are examples of steps to expand the space S3 by moving or swapping at least one of the support parts, the first support part and the second support part. As an example, a nut is pre-embedded in the upper surface 62a of the lower support part 62.

[0068] A nut is embedded in the lower surface 66a of the upper support portion 61 (step S140). In this embodiment, the cap plate 66 provided on the conventional island equipment 10 is reused as the upper support portion 61. However, the cap plate 66 may be removed and the upper support portion 61 may be fixed so as to span across multiple island columns 11. In this case, a nut may be embedded in the lower surface 61a of the upper support portion 61.

[0069] Step S150: The gaming machine frame 40 is installed on the installation section 60. Next, the gaming machine frame 40 is fixed to the support sections 61 and 62 by bolting (Step S160). For example, a bolt is inserted through one of the bolt holes of the base sections 43 and 44 that make up the gaming machine frame 40, and then screwed into a nut on the upper support section 61 to fix it in place. This forms the upper fixing mechanism 61b. For example, a bolt is inserted through the other bolt hole of the base sections 43 and 44 that make up the gaming machine frame 40, and then screwed into a nut on the lower support section 62 to fix it in place. This forms the lower fixing mechanism 62b. In steps S150 and S160, the orientation of the gaming machine frame 40 should be selected according to whether to install the gaming machine 20P or the gaming machine 20S. When installing the gaming machine 20P, the gaming machine frame 40 should be fixed in orientation P1. When installing the gaming machine 20S, it is best to fix the gaming machine frame 40 in position P2.

[0070] Steps S150 and S160 are examples of steps for installing the gaming machine frame 40 in the expanded space S3. Step S150 includes installing the gaming machine frame 40 so that it is in position P1 or position P2. Step S160 is an example of a step for providing a fixing mechanism to fix the gaming machine frame 40 to at least one of the upper support portion 61 and the lower support portion 62. In this way, when the gaming machine frame 40 is in position P1, the upper support portion 61 and the end portion E1 can be fixed by the upper fixing mechanism 61b, and the lower support portion 62 and the end portion E2 can be fixed by the lower fixing mechanism 62b. Also, when the gaming machine frame 40 is in position P2, the upper support portion 61 and the end portion E2 can be fixed by the upper fixing mechanism 61b, and the lower support portion 62 and the end portion E1 can be fixed by the lower fixing mechanism 62b.

[0071] The game machine 20 is attached to the game machine frame 40 (step S170). When attaching game machine 20P, game machine 20P is placed on the surface 45b of the third base 45. The top plate of frame W is fixed to the first base 43 of the game machine frame 40. The bottom plate of frame W is fixed to the third base 45 of the game machine frame 40. When attaching game machine 20S, game machine 20S is placed on the inner surface 43b of the first base 43. The top plate of housing B is fixed to the third base 45 of the game machine frame 40. The bottom plate of housing B is fixed to the first base 43 of the game machine frame 40. When the game machine frame 40 is in position P1, the surface 45b of the third base 45 becomes the mounting surface on which game machine 20P is placed. When the gaming machine frame 40 is in position P2, the inner surface 43b of the first base 43 becomes the mounting surface on which the gaming machine 20S is placed.

[0072] The unit frame 50 is installed in the installation section 60 (step S180). The unit frame 50 is installed adjacent to the gaming machine frame 40. In step S180, the orientation of the unit frame 50 should be selected according to whether to install the management unit 30N or the management unit 30W. When installing the management unit 30N, the unit frame 50 should be fixed in orientation p1. When installing the management unit 30W, the unit frame 50 should be fixed in orientation p2.

[0073] The management unit 30 is attached to the unit frame 50 (step S190). When the management unit 30N is attached, the management unit 30N is placed on the surface 55b of the third base 55. 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 the management unit 30W is attached, the management unit 30W is placed on the inner surface 53b of the first base 53. The top plate of the housing 30B is fixed to the third base 55 of the unit frame 50. The bottom plate of the housing 30B is fixed to the first base 53 of the unit frame 50. When the management unit 30W is attached, the banknote identification unit 31 is placed on the surface 55a of the third base 55. 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. In addition, the management unit 30N or the banknote identification unit 31 is connected to the banknote transport unit 32. Communication lines are connected to the gaming machine 20, the management unit 30, the banknote identification unit 31, and other external devices. This completes the installation of the gaming machine frame 40, the unit frame 50, the gaming machine 20, the management unit 30, and the banknote identification unit 31. Furthermore, in the installation area 60 (space S3), the parts where the gaming machine frame 40 or the unit frame 50 are not installed may be sealed by placing decorative members.

[0074] (How to replace a gaming machine) First, remove the gaming machine 20 from the gaming machine frame 40. If installing a gaming machine 20 of the same type as the removed gaming machine 20, attach the new gaming machine 20 to the gaming machine frame 40. Then, complete the work. On the other hand, if installing a gaming machine 20 of a different type than the removed gaming machine 20, it is advisable to select the orientation of the gaming machine frame 40 according to the newly installed gaming machine 20. When installing gaming machine 20P, it is advisable to fix the gaming machine frame 40 in orientation P1. In this case, the first face M1, which has the predetermined decoration, is positioned towards the player. When installing gaming machine 20S, it is advisable to fix the gaming machine frame 40 in orientation P2. In this case, the second face M2, which has the predetermined decoration, is positioned towards the player.

[0075] Next, the gaming machine 20 is attached to the gaming machine frame 40. When attaching the gaming machine 20P, the top plate of frame W is fixed to the first base 43 of the gaming machine frame 40. The bottom plate of frame W is fixed to the third base 45 of the gaming machine frame 40. When attaching the gaming machine 20S, the top plate of housing B is fixed to the third base 45 of the gaming machine frame 40. The bottom plate of housing B is fixed to the first base 43 of the gaming machine frame 40. After that, the prescribed wiring is performed and the work is completed.

[0076] (How to replace the management unit) First, remove the control unit 30 from the unit frame 50. If installing a control unit 30 with the same width dimensions as the removed control unit 30, attach the new control unit 30 to the unit frame 50. Then, complete the work. On the other hand, if installing a control unit 30 with different width dimensions than the removed control unit 30, it is advisable to select the orientation of the unit frame 50 according to the newly installed control unit 30. When installing control unit 30N, it is advisable to re-fix the unit frame 50 in orientation p1. At this time, the first face m1 with the predetermined decoration is positioned on the player's side. When installing control unit 30W, it is advisable to re-fix the unit frame 50 in orientation p2. At this time, the second face m2 with the predetermined decoration is positioned on the player's side.

[0077] The management unit 30 is attached to the unit frame 50. When the management unit 30N is attached, 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 the management unit 30W is attached, the top plate of the housing 30B is fixed to the third base 55 of the unit frame 50. The bottom plate of the housing 30B is fixed to the first base 53 of the unit frame 50. When the banknote identification unit 31 is attached, 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. After that, the predetermined wiring is performed and the work is completed.

[0078] The effects of this embodiment will now be explained. (1) The management unit 30N, which has a relatively small width, can be housed in space s1a, and the management unit 30W, which has a relatively large width, can be housed in space s1b. This allows the island equipment 10 to install any of the management units 30 with different widths without requiring modifications to the holding section that can hold external equipment. Furthermore, in addition to housing the management units 30, the island equipment 10 can also house the banknote identification unit 31 in space s2. Thus, an installation method can be adopted according to the width of the management unit 30 to be installed, and the management unit 30 and banknote identification unit 31 can be installed easily.

[0079] (2) In a designated amusement parlor, the position for inserting banknotes can be standardized across multiple banknote identification units 31. Therefore, the banknote identification units 31 can be installed in an aesthetically pleasing and convenient manner.

[0080] (3) By simply reversing 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. Furthermore, in the island equipment 10, the banknote identification unit 31 can be installed regardless of whether the management unit 30N or the management unit 30W is installed. Thus, the management unit 30N and the management unit 30W can be easily installed without modifying the holding section capable of holding external equipment.

[0081] (4) The height of the space s2 that can accommodate the banknote identification unit 31 is the same as the height of the banknote transport path. Therefore, in the island equipment 10, multiple banknotes inserted into multiple banknote identification units 31 can be transported by a single banknote transport path.

[0082] (5) Because there are protrusions 56 and 57 that project from side walls 51 and 52 toward the other side wall, the minimum distance between spaces in the width direction Dw in space s1a is shorter than the minimum distance between spaces in the width direction Dw in space s1b. Therefore, even when the management unit 30N is housed in space s1a, the protrusions 56 and 57 bring each side wall and the management unit 30N into close proximity, thus filling any gaps that may occur between the management unit 30N and the side walls. For this reason, regardless of which management unit 30 is installed, it can be installed in an aesthetically pleasing manner without modifying the unit frame 50.

[0083] (6) The opening in the gaming machine frame 40 allows for visibility of at least a portion of the banknote transport path. This makes it easier to inspect the banknote transport path. (7) When the gaming machine 20P is installed, at least a portion of the banknote transport path can be seen when the mounting frame is opened. On the other hand, when the gaming machine 20S is installed, even when the front door is opened, the rear wall of the casing B makes it impossible or difficult to see the banknote transport path. However, in the island equipment 10, even when the gaming machine 20S is installed and the banknote transport path cannot be seen even when the front door is opened, at least a portion of the banknote transport path can be seen through the opening in the gaming machine frame 40. This makes it easier to inspect the banknote transport path, etc., regardless of whether the gaming machine 20P or the gaming machine 20S is installed.

[0084] (8) The height of the opening in the gaming machine frame 40 is such that it corresponds to the height of the banknote transport path. This makes it easier to inspect the banknote transport path from the opening. (9) The space S3 for housing the gaming machine 20 can be expanded by moving or replacing at least one of the cap plate 66 and the lower plate 67. Then, a gaming machine frame 40 capable of housing the gaming machine 20 can be installed in the expanded space S3. Thus, the gaming machine 20 can be replaced.

[0085] (10) The gaming machine frame 40 is installed in orientation P1 or orientation P2 according to the gaming machine 20 to be installed. Therefore, it is easy to install the target gaming machine 20 from among gaming machines 20P and gaming machines 20S.

[0086] (11) By providing fixing mechanisms 61b and 62b, the gaming machine frame 40 can be fixed, making it easier to replace the gaming machine 20. (12) Since the fixing mechanisms 61b and 62b are made up of nuts and bolts, the gaming machine frame 40 can be fixed with a simple configuration.

[0087] (13) The upper fixing mechanism 61b and the lower fixing mechanism 62b can be used regardless of whether the gaming machine frame 40 is to be installed in orientation P1 or orientation P2. Therefore, it is not necessary to modify the mechanism for fixing the gaming machine frame 40 to the island equipment 10 each time the installation configuration of the gaming machine frame 40 is changed. Therefore, the installation configuration of the gaming machine frame 40 can be easily changed to match the type of gaming machine 20. Therefore, the gaming machine 20 can be replaced.

[0088] (14) The recommended height for installing the gaming machine 20 varies depending on the type of gaming machine 20. For example, Patent Document (Japanese Patent Publication No. 2015-228981) discloses an island equipment that allows adjustment of the height when installing the gaming machine 20. However, it is desirable to be able to adjust the installation height of the gaming machine 20 more easily. The island equipment 10 of this embodiment allows the height of the mounting surface (surfaces 43b, 45b) of the gaming machine 20 on the gaming machine frame 40 to be adjusted to the recommended height simply by inverting the gaming machine frame 40 upside down. Therefore, the type of gaming machine 20 can be easily changed.

[0089] (15) The gaming machine 20S has a smaller width than the gaming machine 20P. The gaming machine frame 40 is equipped with protrusions 46 and 47 that project into the space S1. Therefore, even when the gaming machine 20S is installed with the gaming machine frame 40 in position P2, gaps are less likely to occur on the left and right sides of the gaming machine 20S. Thus, the gaming machine can be installed in an aesthetically pleasing manner.

[0090] (16) When the gaming machine frame 40 is in position P2, the protruding parts 46 and 47 are arranged along the edge on the player side (second surface M2 side) in the depth direction Dd. Therefore, the unevenness of the second surface M2 of the gaming machine frame 40 can be reduced, and the aesthetic appearance can be improved.

[0091] (17) Generally, island equipment is decorated to improve the aesthetics of the amusement arcade. For example, sheets with printed patterns are attached to the island equipment. For example, patterns are painted on the island equipment using paint. However, changing the decoration of conventional island equipment requires high technical skill. For this reason, it has been difficult to change the decoration of conventional island equipment. In contrast, in island equipment 10, each surface M1 and M2 in the depth direction Dd of the amusement machine frame 40 is decorated with different decorations. Therefore, the decoration of island equipment 10 can be easily changed by changing the orientation of the amusement machine frame 40.

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

[0093] (19) Generally, island equipment is decorated to improve the aesthetics of the amusement arcade. For example, sheets with printed patterns are attached to the island equipment. For example, patterns are painted on the island equipment using paint. However, changing the decoration of conventional island equipment requires high technical skill. For this reason, it has been difficult to change the decoration of conventional island equipment. In contrast, in island equipment 10, each surface m1 and m2 in the depth direction Dd of the unit frame 50 is decorated with different decorations. Therefore, the decoration of island equipment 10 can be easily changed by changing the orientation of the unit frame 50.

[0094] (20) By opening the inspection door Dr of the gaming machine frame 40, the inside of the island equipment 10 can be inspected and maintenance performed through the space S2. The above embodiments can be implemented with the following modifications. The above embodiments and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0095] The management unit 30N may be connected to the banknote identification unit 31 without having a built-in banknote identifier Nb. When the management unit 30N receives the amount of money inserted from the banknote identification unit 31, it may add it to the remaining balance stored in the management medium. The management unit 30N may also be connected to the banknote identification unit 31 even if it has a built-in banknote identifier Nb. For example, if the installation height and position of the management unit 30N are such that the banknote receiving port 32c of the banknote transport unit 32 can accept the banknotes discharged from the banknote discharge port Nc of the management unit 30N, then it is not necessary to install the banknote identification unit 31 connected to the management unit 30N. For example, if the installation height and position of the management unit 30N are such that the banknote receiving port 32c of the banknote transport unit 32 cannot accept the banknotes discharged from the banknote discharge port Nc of the management unit 30N, then the banknote identification unit 31 connected to the management unit 30N may be installed.

[0096] The management unit 30W may have a built-in banknote identifier and, when banknotes are inserted, add them to the balance stored in the management medium. In this case, the banknote identifier unit 31 may or may not be installed. For example, if the installation height and position of the management unit 30W are such that the banknote receiving port 32c of the banknote transport unit 32 can accept banknotes discharged from the banknote output port of the banknote identifier of the management unit 30W, then the banknote identifier unit 31 connected to the management unit 30W does not need to be installed. For example, if the installation height and position of the management unit 30W are such that the banknote receiving port 32c of the banknote transport unit 32 cannot accept banknotes discharged from the banknote output port of the banknote identifier of the management unit 30W, then the banknote identifier unit 31 connected to the management unit 30W may be installed.

[0097] When installing the management unit 30N, the unit frame 50 may be installed with one end e2 in the height direction Dh positioned upwards and the opposite end e1 positioned downwards. In this case, the installation configuration of the unit frame 50 is preferably the first configuration, where the first surface m1 of the unit frame 50 is positioned towards the player. When installing the management unit 30W, the unit frame 50 may be installed with one end e1 in the height direction Dh positioned upwards and the opposite end e2 positioned downwards. In this case, the installation configuration of the unit frame 50 is preferably the second configuration, where the second surface m2 of the unit frame 50 is positioned towards the player. When installing the banknote identification unit 31, the unit frame 50 should be installed in a position that is appropriate to the height and position at which the banknote receiving port 32c of the banknote transport unit 32 can receive the banknotes discharged from the banknote discharge port 31M of the banknote identification unit 31.

[0098] The banknote transport unit 32 may be configured such that when the unit frame 50 is installed with one end e1 facing upwards and the opposite end e2 facing downwards, the banknote receiving port 32c of the banknote transport unit 32 can receive banknotes discharged from the banknote discharge port 31M of the banknote identification unit 31. In this case, the recommended height of the banknote identification unit 31 is such that when the unit frame 50 is installed with one end e1 facing upwards and the opposite end e2 facing downwards, and the banknote identification unit 31 is installed, the banknote receiving port 32c can receive banknotes discharged from the banknote discharge port 31M. Therefore, the height of space s2 can be said to correspond to the height of the banknote transport unit 32. Consequently, the height of space s2 can also be said to correspond to the height of the banknote transport section 32b (banknote transport path).

[0099] The unit frame 50 may have either the first protrusion 56 or the second protrusion 57. For example, the unit frame 50 may have the first protrusion 56 but not the second protrusion 57. The unit frame 50 may have at least one of the protrusions 56 or the second protrusion 57.

[0100] The unit frame 50 may have a first projection 56 as part of the first side wall 51. The unit frame 50 may have a second projection 57 as part of the second side wall 52. In other words, the first side wall 51 may have a first projection 56 that projects toward the second side wall 52. The second side wall 52 may have a second projection 57 that projects toward the first side wall 51. Thus, at least one of the first side wall 51 and the second side wall 52 may have a projection that projects toward the other side wall. In this case, the minimum distance between the first side wall 51 and the second side wall 52 in space s1a is shorter than the minimum distance between the first side wall 51 and the second side wall 52 in space s1b.

[0101] The method of installing the gaming machine frame 40 is not limited to not moving the cap plate 66 and reusing the cap plate 66 as the upper support part 61. For example, the cap plate 66 may be removed and a new upper support part 61 may be installed. In this case, it is preferable that nuts be embedded in the upper support part 61 beforehand. The method of installing the gaming machine frame 40 is also limited to moving the cap plate 66 upward or downward. Furthermore, when a new upper support part 61 is installed, its lower surface 61a may be located above or below the lower surface 66a of the conventional cap plate 66. Furthermore, the method of installing the gaming machine frame 40 is also limited to reusing the waist plate 67 as the lower support part 62. In this case, the waist plate 67 may be moved downward, moved upward, or not moved at all. In other words, the method of installing the gaming machine frame 40 is limited to expanding the space S3 so that the gaming machine frame 40 can be installed, and the support part to be moved or replaced among the first support part and the second support part may be arbitrarily changed.

[0102] In the method for replacing the gaming machine 20, if the type of gaming machine 20 is not changed, the gaming machine frame 40 may be reversed front to back, and the faces M1 and M2, which have different decorations, may be swapped. According to this example of modification, the decoration can be easily changed even if the type of gaming machine 20 is not changed. Furthermore, it is not necessary to replace the gaming machine 20. In this case, it can be understood as a method of changing the decoration using the gaming machine frame 40.

[0103] In the method for replacing the management unit, if the type of management unit 30 is not changed, the unit frame 50 may be reversed front to back, and the faces m1 and m2 with different decorations may be swapped. According to this example of modification, the decoration can be easily changed even if the type of management unit 30 is not changed. Furthermore, it is not necessary to replace the management unit 30. In this case, it can be understood as a method of changing the decoration using the unit frame 50.

[0104] The surfaces M1 and M2 of the gaming machine frame 40 may be covered with a lenticular sheet. The lenticular sheet has a lenticular lens having multiple convex lenses extending parallel to each other along the height direction Dh, and a composite pattern layer in which multiple types (for example, two types) of patterns are combined for the lenticular lens. With this configuration, even when looking at the same position in the height direction Dh, the pattern that can be seen will differ depending on the angle of the line of sight from the width direction Dw to that same position. Furthermore, if the lenticular sheet is arranged so that the lenticular lens extends along the width direction Dw, different patterns can be seen depending on the angle of the line of sight in the height direction Dh. The surfaces m1 and m2 of the unit frame 50 can be changed in the same way.

[0105] The first face M1 of the gaming machine frame 40 and the first face m1 of the unit frame 50 may be decorated with common elements. The second face M2 of the gaming machine frame 40 and the second face m2 of the unit frame 50 may also be decorated with common elements. One or more of the following can be set as common elements: colors, patterns, and characters. For example, the first faces M1 and m1 may have the same decoration, and the second faces M2 and m2 may have the same decoration. According to this example of modification, by combining the orientation of the gaming machine frame 40 and the orientation of the unit frame 50, it is possible to create a unified decoration or intentionally create different decorations.

[0106] The decoration on the gaming machine frame 40 may be applied to only one of the first surface M1 and the second surface M2. The decoration on the unit frame 50 may be applied to only one of the first surface m1 and the second surface m2. The decoration on the first surface M1 and the second surface M2 is not limited to being applied to their entire surfaces, but may be applied to a part of one or both of the surfaces which can be arbitrarily selected. The decoration on the first surface m1 and the second surface m2 is not limited to being applied to their entire surfaces, but may be applied to a part of one or both of the surfaces which can be arbitrarily selected.

[0107] The protrusions 46 and 47 of the gaming machine frame 40 are not limited to being provided along one edge in the depth direction Dd. For example, the protrusions 46 and 47 may be provided in the central portion in the depth direction Dd. The protrusions 56 and 57 of the unit frame 50 are not limited to being provided along one edge in the depth direction Dd. For example, the protrusions 56 and 57 may be provided in the central portion in the depth direction Dd.

[0108] The protruding portions 56 and 57 of the unit frame 50 may be provided with storage compartments capable of accommodating a predetermined item. For example, the storage compartment may be a recess opening to the first surface m1 side. The predetermined item may be the player's personal belongings such as a keychain and a mobile phone, or it may be the instruction manual for the gaming machine 20.

[0109] The protruding portions 46 and 47 of the gaming machine frame 40 may be configured to include a movable portion supported so as to be displaceable along the width direction Dw, and a biasing portion that biases the movable portion toward the gaming machine 20. This allows the gaming machine 20 and the movable portion to be in close contact and the gap to be further reduced, even if the width dimension or installation position of the gaming machine 20 changes. Similarly, the protruding portions 56 and 57 of the unit frame 50 may be configured to include a movable portion supported so as to be displaceable along the width direction Dw, and a biasing portion that biases the movable portion toward the management unit.

[0110] The order of each step constituting the installation method for the gaming machine frame 40 may be changed as appropriate. For example, the gaming machine 20 may be attached to the gaming machine frame 40 first, and then the gaming machine frame 40 may be installed in the installation section 60. For example, the management unit 30 may be attached to the unit frame 50 first, and then the unit frame 50 may be installed in the installation section 60. The unit frame 50 may be installed first, and then the gaming machine frame 40 may be installed, or the gaming machine frame 40 and the unit frame 50 may be joined together and installed simultaneously.

[0111] The gaming machine frame 40 and the unit frame 50 may be integrated. The gaming machine frame 40 may be capable of holding multiple gaming machines 20. The unit frame 50 may be capable of holding multiple management units 30.

[0112] Next, we will describe the technical concepts that can be understood from the above embodiments and modified examples. (1) Island equipment comprising a holding section capable of holding multiple types of external equipment attached to a gaming machine, wherein the external equipment comprises a first external equipment and a second external equipment, wherein the first external equipment comprises a first type first external equipment and a second type first external equipment having a length along a predetermined direction longer than that of the first type first external equipment, and the holding section has a first side wall and a second side wall as side walls aligned along the predetermined direction, and between the first side wall and the second side wall, a first space for accommodating the first type first external equipment, a second space for accommodating the second type first external equipment and a third space for accommodating the second external equipment are formed.
