Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in gaming machines, there is a demand for providing a gaming machine that has both a noise countermeasure effect and a component breakage suppression effect.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a gaming machine that has both a noise countermeasure effect and a component breakage suppression effect.

Means for Solving the Problems

[0007] In order to achieve the above object, the gaming machine according to the present invention is A housing (e.g., housing 1) is provided, and a back plate (e.g., back plate 3) that constitutes the outer shape of the housing includes a metal sheet (e.g., sheet 40) attached so as to cover the inner surface side. The back plate includes a first back plate opening (e.g., wiring opening 72) for passing a wiring (e.g., outer end plate harness). The sheet includes a first sheet opening (e.g., sheet opening 42) for passing the wiring. The first back plate opening has a first back plate inner surface side opening (e.g., first back plate inner surface side opening G) on the inner surface side of the back plate that is larger than a first back plate outer surface side opening (e.g., first back plate outer surface side opening F) on the outer surface side of the back plate. The first sheet opening is configured to match the first back plate inner surface side opening (e.g.,

[0037] , FIG. 4,

[0063] ). Side plates (e.g., left side plate 5, right side plate 6) that constitute the outer shape of the housing include the sheet attached so as to cover the inner surface side. A top plate (e.g., top plate 2) that constitutes the outer shape of the housing does not include the sheet attached so as to cover the inner surface side. The top plate includes a top plate opening (e.g., top plate opening 2a) for passing a fixture. Inside the housing, a substrate unit (e.g., relay substrate unit) having a predetermined substrate (e.g., relay substrate) is provided. The predetermined substrate is arranged such that the substrate surface faces the top plate (e.g.,

[0058] ,

[0060] ,

[0065] ).

[0008] When a wiring (conductive member) comes into contact with a metal sheet, the sheet may curl or peel off, and there is a risk that components inside the housing may malfunction due to the peeling of the sheet. Also, the wiring (conductive member) may be damaged and broken (such as a wire break). In the gaming machine according to the present invention, since the first sheet opening is configured to match the first back plate inner surface side opening, contact between the wiring (conductive member) and the metal sheet can be suppressed, and occurrence of those problems can be suppressed. Also, by providing a metal sheet on the inner surface sides of the back plate and the side plates, the noise resistance performance can be improved. Thereby, a gaming machine having both a noise countermeasure effect and a component breakage suppression effect can be provided. Also, since no sheet is provided on the top plate, no metal powder is generated when fixing the housing to island equipment. For this reason, it is possible to suppress the metal powder from adhering to a predetermined substrate inside the housing and causing component failure (e.g.,

[0064] ,

[0066] ).

Effect of the Invention

[0009] According to the present invention, it is possible to provide a gaming machine having both a noise countermeasure effect and a component breakage suppression effect.

[0028] The power supply unit 10 is in the shape of a substantially rectangular parallelepiped box, is arranged at the lower left inside the housing 1 (placed on the bottom plate 4), and is fixed to the inner surface of the left side plate 5. The power supply unit 10 is provided with a power switch (not shown). When the power switch is turned on, power is supplied from the power supply unit 10 to each component. Note that power may be supplied to some components even when the power supply unit 10 is in the OFF state. A power cable (power harness) connected to an outlet that supplies commercial power (AC100V) is connected to the power connector provided on the back surface of the power supply unit 10. Specifically, a connector provided at one end of the power harness is connected to the power connector, and a plug provided at the other end of the power harness is connected to the outlet. The power supply board of the power supply unit 10 generates a DC power supply (for example, 5V, 12V, 24V, etc.) from the power sent from outside the gaming machine via the power harness, and supplies power to each component of the gaming machine.

[0029] As shown in FIG. 1, the front door 20 is provided with a door key cylinder 66, and a door key can be inserted into the door key cylinder 66 to unlock the front door 20. Specifically, the front door 20 can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from the initial position. Also, an error cancellation operation can be performed by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from the initial position.

[0030] When medals are inserted into the medal insertion slot 34 of the slot machine 100, the inserted medals are set to the inserted state up to a specified number (specified insertion number). Also, the slot machine 100 can store (retain and store) up to 50 medals in credit. When the MAX bet button 35 is operated in a state where medals are stored in credit, the medals stored in credit are set to the inserted state up to the specified number.

[0031] In the slot machine 100, when medals are inserted through the medal insertion slot 34 or when the MAX bet button 35 is operated to bet a specified number of medals, the operation of the start lever 32 is enabled, and the game can be started. When the enabled start lever 32 is operated, the game starts. When the game starts, each reel starts rotating, and when the rotation speed of each reel reaches a constant speed and becomes a steady rotation, the operation of the stop button 33 is enabled. When the enabled stop button 33 is operated, the rotation of the reel corresponding to the operated stop button 33 stops. When all the reels stop, processes such as paying out medals according to the result of the game and making the game startable again without newly consuming medals are performed, and one game ends.

[0032] Inside the slot machine 100 (cabinet 1), boards such as a main control board (main control means) and a sub-control board (sub-control means) are provided. Note that the sub-control board may be provided on the back side of the front door 20.

[0033] The main control board receives input signals from input means such as the MAX bet button 35, the start lever 32, and the stop button 33, performs various calculations for executing the game, and controls output means such as the reel unit 14 and the hopper unit 11 based on the calculation results. Also, the sub-control board receives signals (information) sent from the main control board, performs various calculations for executing the presentation, and controls various presentation devices such as the liquid crystal display and the speaker based on the calculation results.

[0034] The main control board and the sub-control board are electrically connected, and various information (signals) such as information indicating the game state can be transmitted from the main control board to the sub-control board, but information cannot be transmitted from the sub-control board to the main control board. Also, the functions of each board such as the main control board and the sub-control board are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, and software consisting of a predetermined program stored in advance in the ROM or the like.

[0035] The main control board is provided with a setting change key cylinder (not shown), a setting change button (not shown), etc. Note that the setting change key cylinder and the setting change button may be provided, for example, in the power supply unit 10.

[0036] FIG. 3 is a perspective view showing the inside of the housing 1 of the slot machine 100. An external terminal board 67 is provided inside the housing 1. In the present embodiment, the external terminal board 67 is attached to the inner surface of the right side plate 6. The external terminal board 67 is provided for connecting the gaming machine to external electronic devices (data display devices, hall computers, etc.), and various external information signals representing the state of the gaming machine and the like are output from the external terminal board 67 toward the external electronic devices. One end of an outer end plate harness (outer end plate cable) is connected to the connector of the external terminal board 67, and the other end of the outer end plate harness is connected to an external electronic device.

[0037] FIG. 4 is a view of the housing 1 seen from the front side. A metal sheet 40 (shield sheet) is attached to the inner surface of the back plate 3 (substantially the entire inner surface side). The metal sheet 40 is provided to suppress external noise from affecting various components (such as boards) arranged inside the housing 1 (causing the components to malfunction, etc.). That is, the sheet 40 is provided to improve noise resistance performance. The thickness of the sheet 40 is less than 1 mm, and in the present embodiment, it is about 0.1 mm to 0.3 mm.

[0038] The back plate 3 has a plurality of openings (back plate openings). The plurality of openings include a wiring opening 70 (first back plate opening) for passing a wiring (harness), a heat radiation opening 80 (second back plate opening) for releasing the heat inside the housing 1 to the outside, and a supply opening 90 (third back plate opening) for supplying gaming medals from the back side (outer surface side) of the housing 1 to the inside of the housing 1 (hopper unit 11). Although not shown, an opening / closing lid member is attached to the supply opening 90, and by opening the lid member, access can be made from the back side of the housing 1 to the inside of the housing 1.

[0039] At least one wiring opening 70 is provided. In the present embodiment, as the wiring opening 70, at least a wiring opening 71 for passing a power harness connected to the power supply unit 10 and a wiring opening 72 for passing an outer end plate harness connected to the external terminal plate 67 are provided. The harness (power harness or outer end plate harness) is configured by covering a conductor (copper wire) with an insulator (insulating material: for example, vinyl chloride).

[0040] At least one heat dissipation opening 80 is provided, and in the present embodiment, three heat dissipation openings 80 are provided. It can be said that the heat dissipation opening 80 is not an opening for passing a harness (putting things in and out).

[0041] In the present embodiment, first, the sheet 40 is attached to the back plate 3 in a state where no opening is provided, and then holes are drilled in both the back plate 3 and the sheet 40 with a drill or the like, so that each opening and the corresponding sheet opening are formed.

[0042] The shape of the wiring opening 70 is substantially circular (round hole, slotted hole, etc.). Note that the shape of the wiring opening 70 is not limited to a substantially circular shape and may be substantially square (square, rectangle, etc.). Also, the shape of the heat dissipation opening 80 is a slotted hole (or rectangle) that is long in the left - right direction. Note that the shape of the heat dissipation opening 80 is not limited to a slotted hole and may be a round hole (may be substantially circular), or may be substantially square. Also, the shape of the replenishment opening 90 is substantially square.

[0043] (Specific processing) The following specific processing is performed on the wiring opening 70. On the other hand, no specific processing is performed on the heat dissipation opening 80. In other words, the wiring opening 70 is an opening (hole) subjected to specific processing, but the heat dissipation opening 80 is not an opening (hole) subjected to specific processing.

[0044] As a specific process, there is a counterbore process. FIG. 5 is a perspective view of a wiring opening 72 for passing an outer end plate harness as viewed from the lower front side. FIG. 6 is a cross-sectional view taken along line A-A shown in FIG. 4. Here, the counterbore process means a process of forming a stepped portion at the opening (edge). The wiring opening 72 subjected to the counterbore process includes, as shown in FIG. 6, a small opening 72a and a large opening 72b. The small opening 72a is formed on the outer surface side (outside) of the back plate 3 (housing 1). The depth (width in the front-rear direction) of the small opening 72a is about 13 mm. The large opening 72b is formed on the inner surface side (inside) of the back plate 3 (housing 1). The depth (width in the front-rear direction) of the large opening 72b is about 2 mm.

[0045] The diameter (inner diameter) of the small opening 72a is about 30 mm. Here, regarding the wiring opening 72, if the opening (edge, opening end) on the outer surface side of the back plate 3 is referred to as the "first back plate outer surface side opening F", the diameter of the first back plate outer surface side opening F is about 30 mm.

[0046] Also, the diameter (inner diameter) of the large opening 72b is about 40 mm. Here, regarding the wiring opening 72, if the opening (edge, opening end) on the inner surface side of the back plate 3 is referred to as the "first back plate inner surface side opening G", the diameter of the first back plate inner surface side opening G is about 40 mm.

[0047] In this embodiment, the first back plate inner surface side opening G is larger (in diameter) than the first back plate outer surface side opening F.

[0048] The stepped portion X in the wiring opening 72 has a depth of about 2 mm and a width of about 5 mm. The stepped portion X is formed over the entire circumference of the hole. Note that since the small opening 72a is formed so as to penetrate in the front-rear direction among the small opening 72a and the large opening 72b, in this embodiment, the small opening 72a may be referred to as a "through hole" in some cases.

[0049] Since it is repetitive, the description will be omitted, but the wiring opening 71 for passing the power harness is also countersunk in the same manner as the wiring opening 72, and includes a small opening, a large opening, a stepped portion, a first back plate outer surface side opening, and a first back plate inner surface side opening.

[0050] FIGS. 7(a) and 7(b) show a case where a process different from the countersinking process is performed on the wiring opening 72. In the present embodiment, the specific process is the countersinking process, but the specific process may be the chamfering process shown in FIG. 7(a) or the rounding process shown in FIG. 7(b). Even when the chamfering process or the rounding process is performed in this way, the first back plate inner surface side opening G is larger (in diameter) than the first back plate outer surface side opening F. The specific process can be said to be a process of making the first back plate inner surface side opening larger than the first back plate outer surface side opening.

[0051] In the present embodiment, a specific process is performed on the wiring opening 70 (wiring opening 71 and wiring opening 72) for passing the harness, and the wiring opening 70 is such that the opening on the inner surface side of the back plate 3 (housing 1) is larger than the opening on the outer surface side of the back plate 3.

[0052] The sheet 40 includes a sheet opening (sheet opening portion) corresponding to the wiring opening 70. As shown in FIG. 6, the sheet opening corresponding to the wiring opening 72 is defined as the sheet opening 42 (first sheet opening). The sheet opening 42 is formed so as to be aligned (matched) with the first back plate inner surface side opening G (rather than the first back plate outer surface side opening F). Being aligned (matched) means that the sizes of the openings (diameters) are the same or substantially the same as each other. Since it is repetitive, the description will be omitted, but the sheet opening (first sheet opening) corresponding to the wiring opening 71 for passing the power harness is also formed so as to be aligned (matched) with the first back plate inner surface side opening of the wiring opening 71. In the present embodiment, the sheet opening corresponding to the wiring opening 70 is formed to be larger than the through hole (for example, the small opening 72a shown in FIG. 6) of the wiring opening 70.

[0053] By aligning the sheet opening (first sheet opening) corresponding to the wiring opening 70 with the inner surface opening of the first back plate (by moving the position of the edge of the sheet 40 outward), it is possible to suppress the harness from contacting the sheet 40. By suppressing the harness from contacting the sheet 40, the following effects can be achieved. (1) When the harness contacts the sheet 40, the edge of the sheet 40 may curl, a part of the sheet 40 may peel off (a part may tear), and the peeled-off sheet 40 may contact the substrate in the housing 1 and cause a circuit short (a component may malfunction). Such problems can be suppressed. (2) When the harness contacts (rub against) the edge of the sheet 40, there may be a problem that the harness may be damaged (the coating of the harness may be broken) and there is a risk of disconnection or the like. Such problems can be suppressed. Also, even if the coating of the harness is peeled off and the conductor is exposed, the possibility of the conductor contacting the sheet 40 (electrically conducting) can be reduced. According to the present embodiment, it is possible to provide a gaming machine having both the noise countermeasure effect by the sheet 40 and the effect of suppressing component breakage (malfunction) by specific processing.

[0054] FIG. 8 is a view of the supply opening 90 seen obliquely from above. In the present embodiment, as shown in FIG. 8, the supply opening 90 is also subjected to countersinking (a stepped portion Y is provided). The supply opening 90 includes a small opening 91 (the outer surface opening L of the first back plate), a large opening 92 (the inner surface opening M of the first back plate), and a stepped portion Y. The stepped portion Y has a depth of about 8 mm and a width (entire circumference) of about 20 mm. The sheet 40 includes a sheet opening 43 (third sheet opening) corresponding to the supply opening 90. The sheet opening 43 is formed so as to be aligned with the inner surface opening M of the first back plate (not the outer surface opening L of the first back plate). By aligning the sheet opening 43 with the inner surface opening M of the first back plate (by moving the position of the edge of the sheet 40 outward), it is possible to suppress the gaming medals or the like from contacting the sheet 40 and the sheet 40 from curling (peeling off) when supplying the gaming medals to the hopper unit 11.

[0055] FIG. 9 is a cross-sectional view taken along line B-B shown in FIG. 4. In the present embodiment, no specific processing is performed on the heat dissipation opening 80 through which no harness is passed. Therefore, the heat dissipation opening 80 is formed such that the inner surface side opening P of the first back plate coincides with the outer surface side opening Q of the first back plate over the entire circumference. In other words, the sizes (diameters) of the inner surface side opening P and the outer surface side opening Q of the first back plate are the same. It can also be said that the heat dissipation opening 80 has no stepped portion and is composed only of a through hole. Unlike the wiring opening 70, the opening on the inner surface side of the back plate 3 (housing 1) of the heat dissipation opening 80 does not extend outward beyond the opening on the outer surface side of the back plate 3.

[0056] The sheet 40 includes a sheet opening 44 (second sheet opening) corresponding to the heat dissipation opening 80. The sheet opening 44 is formed to coincide with the inner surface side opening P of the first back plate. In the heat dissipation opening 80 through which no harness is passed, since contact between the harness and the sheet 40 cannot occur, there is no need to perform specific processing on the heat dissipation opening 80. By omitting the specific processing related to the heat dissipation opening 80, the production efficiency of the component (back plate) can be improved. Also, by not performing specific processing on the heat dissipation opening 80, the area of the sheet 40 can be made larger, and the noise resistance performance can be improved.

[0057] In the present embodiment, the case where the sheet 40 is provided on the inner surface side of the back plate 3, and the back plate 3 is provided with the wiring opening 70 (wiring openings 71 and 72) and the heat dissipation opening 80 is shown (see FIG. 4). The housing 1 includes a top plate 2, a back plate 3, a bottom plate 4, a left side plate 5, and a right side plate 6. The sheet 40 may be provided on the inner surface side of the plates other than the back plate 3, and the plate may be provided with the wiring opening 70 (wiring openings 71, 72) and / or the heat dissipation opening 80. In other words, the sheet 40 may be provided on the inner surface side of at least one plate, and the plate may be provided with the wiring opening 70 (wiring openings 71, 72) and / or the heat dissipation opening 80. Also, the wiring opening 70 (with specific processing) and the heat dissipation opening 80 (without specific processing) may be provided on separate plates. Further, the wiring opening 71 for the power harness and the wiring opening 72 for the outer end plate harness may be provided on separate plates.

[0058] In this embodiment, in addition to the inner surface side of the back plate 3, when a sheet 40 is also provided on the inner surface side of the side plates (left side plate 5 and / or right side plate 6), the noise resistance performance can be further improved. Further, when the sheet 40 is provided on the inner surface side of the top plate 2 and / or the bottom plate 4, the noise resistance performance can be further improved.

[0059] By the way, the top plate 2 is provided with an opening (top plate opening 2a shown in FIG. 3: screw hole) through which a fixture (for example, a screw) for fixing the housing 1 to the island equipment in the game hall is passed (inserted). The fixture is screwed into the top plate opening 2a from the inner surface side of the top plate 2 and tightened (screwed from the bottom upward). Also, inside the housing 1, a board unit (for example, a relay board unit) having a predetermined board (for example, a relay board) is provided. The board unit includes a board and a case for housing the board, and components (electronic components, connectors, etc.) are arranged on the board surface of the board. Further, the case is provided with a connector opening for exposing the connector. The board is arranged such that the board surface faces the top plate 2.

[0060] When the sheet 40 is attached to the inner surface side of the top plate 2, there is a risk that the sheet 40 will be cut as the fixture is inserted into the top plate opening 2a, and metal powder (dust) will fall downward. If the metal powder falls and enters the board unit (through the connector opening), there is a risk that the circuit of the board will short-circuit (the components will malfunction). Therefore, among the inner surface sides of the housing 1, the inner surface side of the top plate 2 may be configured not to be provided with the sheet 40. That is, prevention of component failure may be prioritized over noise countermeasures. In this case, it is possible to prevent component failure due to the sheet 40 being cut and metal powder falling when the housing 1 is fixed to the island equipment.

[0061] In addition, in the present embodiment, although a harness (wiring) is passed through the wiring opening 70 (wiring openings 71 and 72) subjected to specific processing, the member passed through the wiring opening 70 is not limited to wiring, and may be other members (conductive members: gaming medals, screws, nails, etc.). Further, the wiring opening 70 may be a medal supply hole, a screw hole, or a nail hole. Since the wiring opening 70 is subjected to specific processing, contact between the other member and the sheet 40 can be suppressed.

[0062] The gaming machine of the present embodiment is a gaming machine including a housing (e.g., housing 1), a predetermined plate (e.g., back plate 3, bottom plate 4) constituting the outer shape of the housing includes a metal sheet (e.g., sheet 40) on the inner surface side, the predetermined plate includes through holes (e.g., small opening 72a, medal supply hole, screw hole, nail hole) for passing conductive members (e.g., wiring, gaming medals, screws, nails), the sheet includes a sheet opening (e.g., sheet opening 42) for passing the conductive member, the sheet opening is larger than the through hole.

[0063] Further, the gaming machine of the present embodiment is a gaming machine including a housing (e.g., housing 1), a back plate (e.g., back plate 3) constituting the outer shape of the housing includes a metal sheet (e.g., sheet 40) on the inner surface side, the back plate includes a first back plate opening (e.g., wiring opening 72) for passing wiring (e.g., outer end plate harness), the sheet includes a first sheet opening (e.g., sheet opening 42) for passing the wiring, the first back plate opening is such that a first back plate inner surface side opening (e.g., first back plate inner surface side opening G) on the inner surface side of the back plate is larger than a first back plate outer surface side opening (e.g., first back plate outer surface side opening F) on the outer surface side of the back plate, the first sheet opening is configured to match the first back plate inner surface side opening.

[0064] When a wiring (conductive member) comes into contact with a metal sheet, the sheet may curl or peel off, and there is a risk that components inside the housing may malfunction due to the peeling of the sheet. Also, the wiring (conductive member) may be damaged and break (such as open circuit). In the gaming machine of this embodiment, contact between the wiring (conductive member) and the metal sheet can be suppressed, and occurrence of those problems can be suppressed. Further, by providing a metal sheet on the inner surface side of a predetermined plate (rear plate), noise resistance performance can be improved. Thereby, a gaming machine having both a noise countermeasure effect and a component breakage suppression effect can be provided.

[0065] Also, in the gaming machine of this embodiment, Side plates (e.g., left side plate 5, right side plate 6) that constitute the outer shape of the housing are provided with the sheet on the inner surface side, A top plate (e.g., top plate 2) that constitutes the outer shape of the housing is not provided with the sheet on the inner surface side, The top plate is provided with a top plate opening (e.g., top plate opening 2a) for passing a fixture, Inside the housing, a board unit (e.g., relay board unit) having a predetermined board (e.g., relay board) is provided, The predetermined board is arranged such that the board surface faces the top plate.

[0066] By also providing a sheet on the side plates, the noise resistance performance can be further improved. Also, by not providing a sheet on the top plate, generation of metal powder when fixing the housing to island equipment can be suppressed, and adhesion of the metal powder to the board inside the housing and malfunction of components can be suppressed.

[0067] Also, in the gaming machine of this embodiment, The rear plate is provided with a second rear plate opening (e.g., heat dissipation opening 80) for heat dissipation, The sheet is provided with a second sheet opening (e.g., sheet opening 44) corresponding to the second rear plate opening, The second rear plate opening is configured such that a second rear plate inner surface side opening (second rear plate inner surface side opening P) on the inner surface side of the rear plate coincides with a second rear plate outer surface side opening (second rear plate outer surface side opening Q) on the outer surface side of the rear plate, The second sheet opening is configured to match the inner surface side opening of the second back plate.

[0068] Regarding the heat dissipation holes, by aligning the opening on the inner surface side of the back plate with the opening on the outer surface side of the back plate, and also aligning the second sheet opening with the opening on the inner surface side of the back plate, the area of the sheet can be made larger and the noise resistance performance can be improved.

[0069] FIG. 10 shows the lower right part on the inner surface side of the back plate 3, which is the position on the back side of the cash box 12 (FIG. 3). On the back plate 3, a first conduction bar 111 (first sensor) and a second conduction bar 112 (second sensor) are provided as a pair of conduction bars. The first conduction bar 111 and the second conduction bar 112 protrude forward by a predetermined length. Also, the first conduction bar 111 and the second conduction bar 112 are arranged in a vertical (up and down) row at a predetermined interval. Metal fittings (crimp terminals, connection terminals) are connected to the base parts of the first conduction bar 111 and the second conduction bar 112, and the metal fittings are connected to a harness (wiring).

[0070] The first conduction bar 111 and the second conduction bar 112 can be accommodated (enter) inside the cash box 12. As described above, surplus medals from the hopper unit 11 are supplied to the cash box 12. When the game medals are supplied to the cash box 12, the game medals gradually accumulate inside the cash box 12 and come into contact with the lower second conduction bar 112. At this point, the first conduction bar 111 and the second conduction bar 112 are not electrically conductive.

[0071] Furthermore, when the game medals are supplied to the cash box 12, the accumulated game medals come into contact with the upper first conduction bar 111. At this time, the first conduction bar 111 and the second conduction bar 112 are electrically connected. When the first conduction bar 111 and the second conduction bar 112 are electrically connected, a signal is input to the main control board, and the main control board detects an error (cash box full error) based on the input of the signal. The main control board transmits a command indicating the detection of the error to the sub-control board, and when the sub-control board receives the command, it notifies the occurrence of the error via the effect device. As a result, the store clerk at the game parlor can notice the occurrence of the error and perform operations to eliminate the error.

[0072] In this embodiment, the periphery of the first conduction bar 111 and the second conduction bar 112 on the back plate 3 is a recess 120. The recess 120 is in a substantially vertically long rectangular shape and is recessed by a predetermined length (for example, about 5 mm) toward the rear side. No specific processing (drilling) is performed on the recess 120. Here, regarding the recess 120, the opening on the inner surface side of the back plate 3 is the inner surface side opening T.

[0073] The sheet 40 is provided with a sheet opening 45 (fourth sheet opening) corresponding to the recess 120. The sheet opening 45 is formed so as to be aligned with the inner surface side opening T. As a result, the sheet 40 is not provided inside the recess 120 (bottom surface and side surfaces), and the members (for example, wood) constituting the back plate 3 are exposed inside the recess 120.

[0074] (Modification example) In this embodiment, a case where a metal sheet 40 is attached to the inner surface side of a wooden board (for example, the back board 3) and a specific process is performed on the wiring openings 70 (wiring opening 71 and wiring opening 72) is shown. In this modification, at least one board (the back board 3) constituting the housing 1 is made of metal, and the sheet 40 is not attached to the inner surface side of the board. By making at least one board (the back board 3) of the housing 1 made of metal, the noise resistance performance can be improved (even without providing the sheet 40). The metal back board 3 is provided with a wiring opening for a power harness (or an outer end plate harness). Since the wiring opening is an opening (hole) provided in the metal board, if the harness contacts the opening, the harness is likely to be damaged. No specific process is performed on the wiring opening according to this modification. In this modification, instead of the specific process, a rubber (non-conductive material) ring is attached to the wiring opening. The annular rubber ring is fitted so as to cover the entire circumference of the opening of the wiring opening, and the harness passes through the inside of the ring. Therefore, the harness can come into contact with the rubber ring but does not contact the metal back board 3 (the opening thereof). Thereby, it is possible to prevent the harness from being damaged (broken). In this modification, although the metal board (for example, the back board 3) is provided with a heat dissipation opening, a rubber ring is not attached to the heat dissipation opening through which no wiring passes.

[0075] (Second Embodiment) Next, a second embodiment of the present invention will be described. Since the gaming machine according to this embodiment basically has the same configuration as the gaming machine of the first embodiment, the description of the same configuration as that of the gaming machine of the first embodiment will be omitted or simplified.

[0076] The gaming machine of this embodiment is a gaming machine 101 that uses gaming value as electronic information without using gaming medals as gaming media, and the game is played by consuming or granting gaming value. The gaming machine 101 (Fig. 11) is a so-called smart pachislo (registered trademark). Different from a conventional slot machine that inserts physical medals when playing a game and pays out physical medals when winning a combination, the gaming machine 101 uses gaming value as electronic information without using physical medals, and is a gaming machine (medal-less gaming machine) in which gaming value is consumed or granted by the game. Note that the gaming value in a medal-less gaming machine corresponds to the medal which is the gaming value in a conventional slot machine, and since the gaming value in a medal-less gaming machine can be regarded as a virtual medal (electronified medal), the gaming value in this embodiment may be referred to as a medal (gaming medal). Also, hereinafter, the number of gaming values may be regarded as the number of virtual medals, and the number of gaming values may be indicated as "~ pieces" or "~ units".

[0077] Fig. 11 is a perspective view of the gaming machine 101 seen from the front side. As shown in Fig. 11, the gaming machine 101 of this embodiment includes a box-shaped housing 1 with an opening on the front side facing the player, and a front door (front panel) 12 that opens and closes the front opening of the housing 1. The front door 12 is divided into an upper door 12a and a lower door 12b, and these upper door 12a and lower door 12b are each freely openable and closable with respect to the housing 11. Note that the front door 12 may have an integrated structure that is not divided into the upper door 12a and the lower door 12b. The housing 1 is formed in a box shape with an opening on the front side (having a front opening). The housing 1 includes a top plate 2, a back plate 3, a bottom plate 4, and left and right side plates 5, 6. Let the left side plate 5 be the left side plate 5 and the right side plate 6 be the right side plate 6. In this embodiment, the top plate 2, the back plate 3, the bottom plate 4, the left side plate 5, and the right side plate 6 are made of wood. Note that some of the plates may be made of resin.

[0078] In this embodiment, the plate surface facing the inside of the housing 1 on the top plate 2, the back plate 3, the bottom plate 4, the left side plate 5, and the right side plate 6 is referred to as the "inner surface". The lower surface of the top plate 2, the front surface of the back plate 3, the upper surface of the bottom plate 4, the right surface of the left side plate 5, and the left surface of the right side plate 6 are the "inner surfaces".

[0079] In this embodiment, the plate surface facing the outside of the housing 1 on the top plate 2, the back plate 3, the bottom plate 4, the left side plate 5, and the right side plate 6 is referred to as the "outer surface". The upper surface of the top plate 2, the back surface of the back plate 3, the lower surface of the bottom plate 4, the left surface of the left side plate 5, and the right surface of the right side plate 6 are the "outer surfaces".

[0080] Inside the housing 11, there are provided a reel unit in which a rotatable first reel 15a, a second reel 15b, and a third reel 15c are unitized, a main control means, a sub-control board, a game value number control board, and the like.

[0081] At approximately the center of the upper door 12a, a liquid crystal display 13 (display means) as an effect device is provided. Various images (effect images) for assisting the game and enlivening the game are displayed on the liquid crystal display 13. Further, on the lower door 12b, a speaker 14 (sound output means) as an effect device is provided. Various effect sounds (music, sound effects, voices, etc.) for assisting the game and enlivening the game are output from the speaker 14. Further, on the front door 12, a lamp 38 (lighting device, lighting means, outer peripheral lamp) for performing notification, effects, etc. is provided. Note that, as an effect device, a movable accessory operable by an actuator or the like may be provided.

[0082] In addition, a display window 16 is provided in the upper door 12a. A reel unit is arranged behind the display window 16 (a first display area 13a described later) such that a part of it is visible through the display window 16. The outer peripheral surfaces of the respective reels 15a to 15c are partitioned into 20 frames (20 areas) at regular intervals, and one of a plurality of types of symbols is arranged in each frame. In other words, a plurality of types of symbols are arranged in a row on the outer peripheral surfaces of the respective reels 15a to 15c. Further, when each of the reels 15a to 15c stops, three symbols (an upper symbol, a middle symbol, and a lower symbol) per reel are displayed through the display window 16. In addition, the display window 16 is provided with upper, middle, and lower parts as display positions for viewing the symbols of the respective reels 15a to 15c, and a winning line is set according to the combination of the display positions of the respective reels 15a to 15c. In the present embodiment, the winning line is constituted by the upper part of the first reel 15a, the middle part of the second reel 15b, and the lower part of the third reel 15c.

[0083] In the present embodiment, the number (prescribed number, prescribed number of sheets) of game values required for one game is set to three. When the prescribed number of game values is inserted, the winning line is activated. When the respective reels 15a to 15c start rotating with the start of the game and an internal lottery is executed to determine either a win or a loss (non-win) of any of the winning combinations. Next, when the combination of symbols corresponding to the winning combination won in the internal lottery is displayed on the winning line when the reels 15a to 15c stop, this winning combination wins, and a process (winning process) corresponding to the winning combination that has won is executed. That is, it is displayed whether or not the winning combination has won based on the combination of symbols displayed through the display window 16 when the reels 15a to 15c stop. The winning line can be said to be a line for determining the winning of the winning combination.

[0084] On the lower door 12b (operation unit installation base), there are provided a bet button 35 operated when betting (inserting) game values, a start lever 32 (game start operation means) operated when starting a game, stop buttons 33 (stop operation means) (stop buttons 33a, 33b, 33c) operated when stopping a rotating reel, an effect button 36 (effect operation means) operated when advancing an effect, etc. Note that as the bet button 35, a MAX bet button (first bet button) operated when betting three (prescribed number) of game values and a 1 - bet button (second bet button) operated when betting one game value may be provided.

[0085] The effect button 36 is operated when advancing an effect (changing the mode of the effect). The effect button 36 is formed to be depressable, and when depressed, for example, the mode of the effect image displayed on the liquid crystal display 13 changes. By providing the effect button 36 and enabling its operation at a predetermined timing, the player's awareness of participating in the game can be enhanced, and the interest of the game can be improved. The effect button 36, for example, becomes in an operable state during the execution of an effect that is expected to shift to a state advantageous to the player, and an image instructing the operation is displayed on the liquid crystal display 13 (PUSH effect). Then, when the effect button 36 is operated, the result of the game (for example, whether or not to shift to an advantageous state) is notified. Note that the effect button 36 is not limited to a button shape and may be a lever shape or the like as long as it is configured to be able to detect the player's operation.

[0086] Also, a door key cylinder 66 is provided on the lower door 12b. By inserting a door key into the door key cylinder 66, the lower door 12b (front door 12) can be unlocked. Specifically, by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from the initial position, the lower door 12b can be unlocked. Note that by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from the initial position, an error cancellation operation may be able to be performed.

[0087] Further, a lower panel 39 is provided on the lower door 12b. A light source (LED) for illumination is provided on the back side of the lower panel 39, and the lower panel 39 is illuminated from behind by the light emitted from this light source.

[0088] Although not shown, a dedicated unit (game value lending device, game medal lending device) as a device for lending game values is provided on the side (right side) of the gaming machine 101. Further, on the front surface of the dedicated unit, there are provided a bill insertion slot into which bills can be inserted, a card insertion / ejection port into which a card (game value management medium) can be inserted / ejected, a lending button (lending operation means), a replay button (lending operation means), a card return button, and the like.

[0089] In the dedicated unit, an operation (pressing operation) on the lending button is received as a lending operation (game value transfer operation) for transferring game values to the gaming machine 101. When the lending button is pressed, it consumes the bills inserted into the bill insertion slot or the stored value stored as the prepaid balance on the card, and a predetermined number (for example, 50 pieces) of game values are credited to the gaming machine 101. Further, in the dedicated unit, an operation (pressing operation) on the replay button is received as a lending operation (game value transfer operation) for transferring game values to the gaming machine 101. When the replay button is pressed, it consumes the game values owned by the player managed by the card (the game values linked to the card), and a predetermined number (for example, 50 pieces) of game values are credited to the gaming machine 101. In the present embodiment, an operation on the lending button or the replay button as the lending operation means is received as a lending operation (game value transfer operation), and based on the lending operation, a predetermined number of game values are transferred (lent) from the dedicated unit to the gaming machine 101.

[0090] On the lower door 12b, there are provided a game medal number display device 211 (game value number display device, game value number display), a counting button 212, and a settlement button 218. The game medal number display device 211 and the counting button 212 are provided on the side (right side) of the lower door 12b. Based on the lending operation in the dedicated unit 200, in the gaming machine 101, a value corresponding to a predetermined number of game values is set in the credit (game value number storage area). The stored value in the game value number storage area can also be referred to as the credit number (storage number, possession number). The credit number (the number of game medals available for the game) is displayed on the game medal number display device 211. The game medal number display device 211 has a 5-digit (or 6-digit) 7-segment display, and the credit number is displayed by the 7-segment display. Note that in the gaming machine 101, the upper limit of the credit number may be set, for example, within the range of values that can be displayed on the game medal number display device 211. In the gaming machine 101, when the bet button 35 is operated with game values stored in credit, the game values stored in credit are set to the input state up to the specified number.

[0091] The game value number control board (game value number control means) controls the number of game values stored in the game value number storage area. The game value number control board increases the credit number by the predetermined number based on a predetermined combination (small combination) winning and a predetermined number of game values being awarded. Also, when an operation to input game values (operation of the bet button 35) is performed at the start of the game, the game value number control board decreases the credit number by the number of input game values. On the game medal number display device 211, a value obtained by subtracting the bet number from the possession number (credit number) is displayed.

[0092] In addition, the game value number control board performs control to receive game values transferred from the dedicated unit to the gaming machine 101. When game values are transferred from the dedicated unit to the gaming machine 101, the game value number control board increases the credit number by the number of game values transferred. Also, the game value number control board performs control to transfer game values from the gaming machine 101 to the dedicated unit. When game values are transferred from the gaming machine 101 to the dedicated unit, the game value number control board decreases the credit number by the number of game values transferred. Further, the game value number control board causes the game medal number display device 211 to display the number of game values stored as credits (credit number), and changes the display content of the game medal number display device 211 according to the increase or decrease of the credit number.

[0093] The counting button 212 is a button that is operated when transmitting (returning, transferring) information (credits) indicating a value corresponding to a predetermined number of credits (all or part of the credit number) to the dedicated unit. The counting button 212 is provided with a pressing part (operation part), and the pressing part is formed so as to be pressable. When the player ends the game or the like, it is possible to transfer the credited game values from the gaming machine 101 to the dedicated unit based on an operation (pressing operation) on the counting button 212 as a counting operation (return operation). Then, when an operation (pressing operation) on the card return button is performed after transferring the game values to the dedicated unit, a card that enables the player to grasp the number of game values owned by the player is discharged from the dedicated unit (card insertion / ejection port).

[0094] Based on the lending operation in the dedicated unit, a predetermined number of game values (game medals) are given to the gaming machine 101 (the credit count is incremented). Next, when the bet button 35 is operated, the game values are set to the input state up to the specified number, and the value corresponding to the number of game values (number of game medals) set to the input state is subtracted from the credit count. That is, the number of game values displayed on the game medal number display device 211 decreases. When the specified number of game values are set to the input state, the operation of the start lever 32 becomes effective, that is, the state where the game can be started. Next, when a game start operation is performed on the activated start lever 32, the rotation of each reel 15a to 15c starts. Next, when the rotation speed of the reel increases to a predetermined speed and enters the steady rotation state, the operation of the stop buttons 33a to 33c becomes effective. Next, when the activated stop buttons 33a to 33c are operated, the rotation of the corresponding reel stops. Next, when the rotation of all the reels 33a to 33c stops, depending on the result of the game, a process of giving a predetermined number of game values (adding to the credit) and a process of making it possible to start the game again without newly consuming the game values (replay process) are performed, and one game (one play) ends. Also, when the count button 212 is operated, a predetermined number of credits (game medals) are transmitted (returned) to the dedicated unit. Then, when a card return operation is performed in the dedicated unit, the card storing the predetermined information is discharged from the dedicated unit 200.

[0095] In the gaming machine 101, when the settlement button 218 is operated (pressed) while the gaming value is set to the input state (bet), the input gaming value is returned as credit. The settlement button 218 is a button that is operated when returning the gaming value input (set to the input state) by operating the bet button 35 to credit (the gaming value number storage area). In other words, based on the operation of the settlement button 218, a process (input return process) for returning the gaming value set to the input state to credit is executed. The input return process is a process in which the setting of the input state of the gaming value is canceled, and a value corresponding to the number of gaming values set to the input state is added to the credit number (the stored value in the gaming value number storage area). When the settlement button 218 is operated while there is a gaming value set to the input state, based on this, the gaming value is returned (returned) to credit, and the number of gaming medals displayed on the gaming medal number display device 211 increases.

[0096] The main control board is provided with a setting change key cylinder, a setting change button, etc. Note that the setting change key cylinder and the setting change button may be provided in other parts such as a power unit, for example. The setting change key cylinder (setting key switch) has two states: an OFF state and an ON state. In other words, it is possible to switch between the OFF state and the ON state. The setting change key cylinder is formed so that a setting key can be inserted. The setting change key cylinder is in the OFF state in the initial state. When the inserted setting key is rotated 90 degrees clockwise from the initial position, the state of the setting change key cylinder switches from the OFF state to the ON state. When the setting key is rotated 90 degrees counterclockwise so that the state of the setting change key cylinder becomes the initial position from the position where the state is the ON state, it switches from the ON state to the OFF state. Also, the setting change button can be pressed.

[0097] The main control board receives input signals from input means such as the bet button 35, the start lever 32, and the stop buttons 33a to 33c, performs various calculations for executing the game, and controls output means such as the reel unit based on the calculation results.

[0098] The sub-control board receives signals sent from the main control board and input signals from input means such as the effect button 36, performs various calculations for executing effects, and controls effect devices such as the liquid crystal display 13 and the speaker 14 based on the calculation results.

[0099] The main control board and the sub-control board are electrically connected, and various information (signals) such as information indicating the game state can be transmitted from the main control board to the sub-control board, but information cannot be transmitted from the sub-control board to the main control board. Also, the functions of each board such as the main control board and the sub-control board are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, and software consisting of a predetermined program stored in advance in the ROM or the like.

[0100] Conventional slot machines were equipped with a medal insertion slot, a tray, a hopper unit, a cash box, etc., but the gaming machine 101 does not have them.

[0101] FIG. 12 is a perspective view showing the inside of the housing 1. Inside the housing 1, a power supply unit 210 incorporating a power supply board (power supply means) for supplying power to each component is arranged. The power supply unit 210 has a substantially rectangular parallelepiped box shape and is arranged at the lower left inside the housing 1 (placed on the bottom plate 4). The power supply unit 210 is provided with a power switch (not shown). When the power switch is turned ON, power is supplied from the power supply unit 210 to each component. Note that power may be supplied to some components even when the power supply unit 210 is in the OFF state. Although not shown, a power cable (power harness) connected to a power outlet for supplying commercial power (AC100V) is connected to the power connector provided on the power supply unit 210. Specifically, a connector provided at one end of the power harness is connected to the power connector, and a plug provided at the other end of the power harness is connected to the power outlet. The power supply board of the power supply unit 210 generates a DC power supply (for example, 5V, 12V, 24V, etc.) from the power sent from outside the gaming machine via the power harness and supplies power to each component of the gaming machine.

[0102] Inside the housing 1, on the inner surface side of the left side plate 5, a lending device connection terminal board 220 for game balls or the like is attached. The lending device connection terminal board 220 for game balls or the like is a connection terminal board for connecting the gaming machine 101 and a dedicated unit. In other words, the gaming machine 101 and the dedicated unit are connected via the lending device connection terminal board 220 for game balls or the like. One end of a terminal board harness 221 is connected to the connector of the lending device connection terminal board 220 for game balls or the like, and the other end of the terminal board harness 221 is connected to the dedicated unit. Note that the dedicated unit is connected to an external electronic device (such as a hall computer).

[0103] Similar to the gaming machine of the first embodiment, a metal sheet 40 is attached to the inner surface side of the housing 1 (for example, the back plate 3) in the gaming machine of this embodiment. Also, a wiring opening 70 (first back plate opening) and a heat radiation opening 80 (second back plate opening) are provided in the plate where the sheet 40 is provided (hereinafter referred to as the back plate 3). As the wiring opening 70, there are at least a wiring opening 71 for passing a power harness connected to the power supply unit 210 and a wiring opening 72 for passing a terminal board harness 221 connected to the lending device connection terminal board 220 for game balls and the like.

[0104] The wiring opening 70 through which the harness passes is subjected to a specific process (for example, drilling), but the heat radiation opening 80 through which the harness does not pass is not subjected to a specific process (for example, drilling). The wiring opening 70 has a larger (diameter) on the inner surface side opening of the first back plate than on the outer surface side opening of the first back plate. The wiring opening 70 is such that the opening on the inner surface side of the back plate 3 (housing 1) is larger than the opening on the outer surface side of the back plate 3.

[0105] The sheet 40 includes a sheet opening (for example, the sheet opening 42 in FIG. 6) corresponding to the wiring opening 70. Also, the sheet 40 includes a sheet opening (for example, the sheet opening 44 in FIG. 9) corresponding to the heat radiation opening 80.

[0106] By aligning the sheet opening (the first sheet opening) corresponding to the wiring opening 70 (wiring opening 72 in FIG. 6) with the first backplane inner surface side opening (first backplane inner surface side opening G in FIG. 6) (by moving the position of the end of the sheet 40 outward), it is possible to suppress the harness from contacting the sheet 40. By suppressing the harness from contacting the sheet 40, the following effects can be achieved. (1) When the harness contacts the sheet 40, the end of the sheet 40 may curl up, a part of the sheet 40 may peel off (a part may tear), and the peeled-off sheet 40 may contact the substrate in the housing 1 and cause a circuit short (a component failure). Such problems can be suppressed. (2) When the harness contacts (rub against) the end (edge) of the sheet 40, there may be a problem that the harness may be damaged (the covering of the harness may be broken) and there is a risk of disconnection or the like. Such problems can be suppressed. Also, if the covering of the harness is peeled off and the conductor is exposed, the possibility of the conductor contacting the sheet 40 (being electrically conductive) can be reduced. According to the present embodiment, it is possible to provide a gaming machine having both the noise countermeasure effect by the sheet 40 and the effect of suppressing component breakage (failure) by specific processing.

[0107] Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof. Also, within the scope of the present invention, a free combination of each embodiment, or a modification of any component of each embodiment, or an omission of any component in each embodiment is possible. For example, the configuration of the slot machine and the like is not limited to that of the above-described embodiments. Also, the above-described configuration and the like are not limited to slot machines, and can also be applied to other gaming machines.
