Description

[Technical Field]

[0001] The present invention relates to a gaming machine. [Background technology]

[0002] A slot machine is known as a gaming machine, and is equipped with a plurality of reels with a plurality of symbols arranged on the outer periphery, a start lever, a stop button, etc. In a slot machine, the reels begin to spin in response to a game start operation, and an internal lottery is held using a lottery table. When each reel stops, a symbol combination corresponding to a winning combination in the internal lottery is displayed, and if the winning combination results in a prize, a process corresponding to the winning combination is carried out, such as a medal payout process that pays out medals (game value) or a replay process that allows the player to play again without consuming any more medals.

[0003] Some of such gaming machines have heat dissipation holes in the back panel (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-43312 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, there is a demand for gaming machines that combine noise suppression effects with component damage prevention effects.

[0006] The present invention has been made in consideration of the above circumstances, and aims to provide a gaming machine that combines noise suppression effects and component damage prevention effects. [Means for solving the problem]

[0007] In order to achieve the above object, the gaming machine according to the present invention comprises: A gaming machine equipped with a cabinet (e.g., cabinet 1), A back plate (e.g., back plate 3) that forms the outer shape of the housing has a metal sheet (e.g., sheet 40) on the inner side, the back plate includes a first back plate opening (e.g., wiring opening 72) for routing wiring (e.g., an outer end plate harness); The sheet has a first sheet opening (e.g., sheet opening 42) for passing the wiring through; The first back panel opening has a first back panel inner surface opening (e.g., first back panel inner surface opening G) on the inner surface side of the back panel that is larger than a first back panel outer surface opening (e.g., first back panel outer surface opening F) on the outer surface side of the back panel, The first seat opening is adapted to align with the first back panel inner surface opening.

[0008] If the wiring comes into contact with the metal sheet, the sheet may curl or peel, which may cause components inside the cabinet to malfunction. The wiring may also be scratched and damaged (such as broken wires). In the gaming machine according to the present invention, the first sheet opening is aligned with the first back panel inner opening. This prevents contact between the wiring and the metal sheet, thereby preventing these problems from occurring. Furthermore, providing a metal sheet on the inner side of the back panel improves noise resistance. This provides a gaming machine that combines noise suppression and component damage prevention. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a gaming machine that combines noise suppression effects with component damage prevention effects. [Brief explanation of the drawings]

[0025] In addition, a payout opening 50 for discharging (sending out) medals from inside the slot machine 100 and a receiving tray 38 capable of collecting medals discharged (paid out) from the payout opening 50 are provided at the bottom of the front door 20. A lower panel 39 for decorating the exterior of the gaming machine is provided between the operation unit 30 and the receiving tray 38. A light source (LED) for illumination is provided on the back side of this lower panel 39, and the light from this light source illuminates the lower panel 39 from behind. The lower panel 39 may be formed to be pushable and serve as an effect operation unit having the same function as an effect button.

[0026] As shown in Fig. 2, a reel unit 14 is provided inside the cabinet 1. The reel unit 14 includes three reels 15a, 15b, and 15c each having a plurality of symbols displayed around its periphery, a drive motor (stepping motor) for rotating the reels 15a to 15c, and the like. Each reel is fixed to the output shaft of the corresponding stepping motor.

[0027] Inside the housing 1, on the top surface of the bottom plate 4, there are provided a power supply unit 10 (power supply means) that supplies power to each component, a hopper unit 11 (payout device) that stores medals and pays them out, and a cash box 12 into which surplus medals are sent when the number of medals stored in the hopper unit 11 reaches a certain amount.

[0028] The power supply unit 10 is in the shape of a roughly rectangular parallelepiped box, and is located 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 equipped with a power switch (not shown), and 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 turned off. A power cable (power harness) that is connected to an outlet that supplies commercial power (AC 100V) is connected to a power connector provided on the back of the power supply unit 10. Specifically, a connector provided on one end of the power harness is connected to the power connector, and a plug provided on the other end of the power harness is connected to the outlet. The power supply board of the power supply unit 10 creates DC power (e.g., 5V, 12V, 24V, etc.) from 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 the front door 20 can be unlocked by inserting a door key into the door key cylinder 66. Specifically, the front door 20 can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from its initial position. In addition, an error can be cleared by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from its initial position.

[0030] When medals are inserted into the medal insertion slot 34, the slot machine 100 sets the inserted medals to an inserted state up to a specified number (specified insertion number). Also, the slot machine 100 is capable of storing (accumulating) up to 50 medals as credits, and when the MAX BET button 35 is operated with medals stored as credits, the stored medals are set to an inserted state up to a specified number.

[0031] In the slot machine 100, when medals are inserted through the medal insertion slot 34 or the MAX BET button 35 is operated to bet a specified number of medals, operation of the start lever 32 is enabled, and the machine is ready to start playing. When the enabled start lever 32 is operated, the game begins. When the game starts, each reel begins to spin, and when the rotation speed of each reel reaches a certain speed and the reels start rotating at a steady state, 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 have stopped, a process is performed in which medals are paid out depending on the result of the game, or a process is performed in which the machine is ready to start playing again without consuming any more medals, and one round of play is completed.

[0032] The slot machine 100 (cabinet 1) is provided with boards such as a main control board (main control means) and a sub-control board (sub-control means). 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, start lever 32, and stop button 33, performs various calculations to execute the game, and controls output means such as the reel unit 14 and hopper unit 11 based on the calculation results. The sub-control board also receives signals (information) sent from the main control board, performs various calculations to execute effects, and controls various effect devices such as the LCD display and 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 status can be sent from the main control board to the sub-control board, but information cannot be sent from the sub-control board to the main control board. 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, or by software consisting of a predetermined program pre-stored in ROM, etc.

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

[0036] FIG. 3 is a perspective view showing the inside of the cabinet 1 of the slot machine 100. An external terminal board 67 is provided inside the cabinet 1. In this 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 to connect the gaming machine to external electronic devices (such as a data display device or hall computer), and various external information signals indicating the status of the gaming machine are output from the external terminal board 67 to the external electronic devices. One end of an external terminal board harness (external terminal board cable) is connected to the connector of the external terminal board 67, and the other end of the external terminal board harness is connected to the external electronic device.

[0037] FIG. 4 is a view of the housing 1 as seen from the front side. A metal sheet 40 (shielding sheet) is attached to the inner surface (substantially the entire inner surface) of the back panel 3. The metal sheet 40 is provided to prevent external noise from affecting the various components (such as circuit boards) placed inside the housing 1 (causing the components to malfunction, etc.). In other words, the sheet 40 is provided to improve noise resistance. The thickness of the sheet 40 is less than 1 mm, and in this embodiment is approximately 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 (passing through) wiring (harness), a heat dissipation opening 80 (second back plate opening) for dissipating heat inside the cabinet 1 to the outside, and a supply opening 90 (third back plate opening) for supplying game medals from the back side (exterior side) of the cabinet 1 to the inside of the cabinet 1 (hopper unit 11). Although not shown in the figure, a lid member that can be opened and closed is attached to the supply opening 90, and when the lid member is open, the inside of the cabinet 1 can be accessed from the back side of the cabinet 1.

[0039] At least one wiring opening 70 is provided. In this embodiment, the wiring openings 70 include 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 board 67. 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 this embodiment, three heat dissipation openings 80 are provided. It can be said that the heat dissipation openings 80 are not openings for passing a harness through (for putting things in and out).

[0041] In this embodiment, first, the sheet 40 is attached to the back panel 3 without any openings, and then holes are drilled in both the back panel 3 and the sheet 40 with a drill or the like to form each opening and the corresponding sheet opening.

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

[0043] (Specific processing) The wiring opening 70 has undergone the following special processing. On the other hand, the heat dissipation opening 80 has not undergone the special processing. In other words, the wiring opening 70 is an opening (hole) that has undergone the special processing, but the heat dissipation opening 80 is not an opening (hole) that has undergone the special processing.

[0044] The specific processing includes countersinking. FIG. 5 is a perspective view of the wiring opening 72 for passing the outer end plate harness, seen from below on the front side. FIG. 6 is a cross-sectional view taken along line AA in FIG. 4. Here, countersinking refers to processing for forming a step portion on the opening (edge). As shown in FIG. 6, the countersunk wiring opening 72 includes a small opening 72a and a large opening 72b. The small opening 72a is formed on the outer surface (outside) of the back plate 3 (housing 1). The depth (width in the front-to-back direction) of the small opening 72a is approximately 13 mm. The large opening 72b is formed on the inner surface (inside) of the back plate 3 (housing 1). The depth (width in the front-to-back direction) of the large opening 72b is approximately 2 mm.

[0045] The diameter (inner diameter) of the small opening 72a is about 30 mm. Here, for 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 opening F," the diameter of the first back plate outer surface opening F is about 30 mm.

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

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

[0048] The step portion X in the wiring opening 72 has a depth of approximately 2 mm and a width of approximately 5 mm. The step portion X is formed around the entire circumference of the hole. Of the small opening 72a and the large opening 72b, the small opening 72a is the one that is formed to penetrate in the front-to-rear direction, so in this embodiment, the small opening 72a may be referred to as a "through hole."

[0049] Although the explanation will be omitted to avoid redundancy, the wiring opening 71 for passing the power harness is also countersunk like the wiring opening 72, and is provided with a small opening, a large opening, a step portion, an opening on the outer surface of the first back panel, and an opening on the inner surface of the first back panel.

[0050] 7(a) and 7(b) show cases where a process other than countersinking is performed on the wiring opening 72. In this embodiment, the specific process is countersinking, but the specific process may be C-chamfering as shown in FIG. 7(a) or R-chamfering as shown in FIG. 7(b). Even when C-chamfering or R-chamfering is performed in this way, the first rear panel inner opening G will be larger (in diameter) than the first rear panel outer opening F. The specific process can be said to be a process that makes the first rear panel inner opening larger than the first rear panel outer opening.

[0051] In this embodiment, the wiring opening 70 (wiring opening 71 and wiring opening 72) for passing the harness is specially processed, and the opening on the inner side of the back panel 3 (housing 1) of the wiring opening 70 is larger than the opening on the outer side of the back panel 3.

[0052] The sheet 40 has a sheet opening (sheet opening) corresponding to the wiring opening 70. As shown in FIG. 6, the sheet opening corresponding to the wiring opening 72 is referred to as sheet opening 42 (first sheet opening). The sheet opening 42 is formed to align (match) with the first back panel inner surface opening G (not the first back panel outer surface opening F). "Match" means that the openings (diameters) are the same or approximately the same size. Note that, although redundant explanation will be omitted, the sheet opening (first sheet opening) corresponding to the wiring opening 71 for passing the power harness through is also formed to align (match) with the first back panel inner surface opening of the wiring opening 71. In this embodiment, the sheet opening corresponding to the wire opening 70 is formed to be larger than the through-hole of the wire opening 70 (for example, the small opening 72a shown in FIG. 6).

[0053] By aligning the sheet opening (first sheet opening) corresponding to the wiring opening 70 with the opening on the inner surface of the first back panel (by positioning the edge of the sheet 40 outward), the harness can be prevented from coming into contact with the sheet 40. By preventing the harness from coming into contact with the sheet 40, the following effects are achieved: (1) If the harness comes into contact with the sheet 40, the edge of the sheet 40 may be turned up, a portion of the sheet 40 may peel off (or tear), and the peeled sheet 40 may come into contact with a circuit board inside the housing 1, causing a short circuit (component failure). However, this prevents such problems from occurring. (2) If the harness comes into contact (rubs) with the edge (edge) of the sheet 40, the harness may be damaged (the harness coating may be torn), potentially resulting in a disconnection. However, this prevents such problems from occurring. Furthermore, if the harness coating is peeled off and the conductor is exposed, the likelihood of the conductor coming into contact with the sheet 40 (becoming electrically conductive) is reduced. According to this embodiment, it is possible to provide a gaming machine that combines the noise suppression effect of the sheet 40 and the component damage (failure) suppression effect of the specific processing.

[0054] FIG. 8 is a view of the supply opening 90 as viewed from diagonally above. In this embodiment, as shown in FIG. 8, the supply opening 90 is also countersunk (a step portion Y is provided). The supply opening 90 has a small opening 91 (first back panel outer surface opening L), a large opening 92 (first back panel inner surface opening M), and the step portion Y. The step portion Y has a depth (depth) of approximately 8 mm and a width (circumference) of approximately 20 mm. The sheet 40 has a sheet opening 43 (third sheet opening) corresponding to the supply opening 90. The sheet opening 43 is formed to align with the first back panel inner surface opening M (rather than the first back panel outer surface opening L). By aligning the sheet opening 43 with the first back panel inner surface opening M (by displacing the edge of the sheet 40 outward), it is possible to prevent the game medals and the like from coming into contact with the sheet 40 when supplying the game medals to the hopper unit 11, thereby preventing the sheet 40 from turning over (peeling off).

[0055] 9 is a cross-sectional view taken along line BB in FIG. 4. In this embodiment, no special processing is performed on the heat dissipation opening 80, through which no harness passes. Therefore, the heat dissipation opening 80 is formed so that the first rear panel inner surface opening P is aligned (matches) with the first rear panel outer surface opening Q along the entire periphery. In other words, the first rear panel inner surface opening P and the first rear panel outer surface opening Q have the same size (diameter). The heat dissipation opening 80 does not have a step and can be said to be composed only of a through hole. Unlike the wiring opening 70, the opening on the inner surface of the rear panel 3 (housing 1) of the heat dissipation opening 80 does not extend further outward than the opening on the outer surface of the rear panel 3.

[0056] The sheet 40 has a sheet opening 44 (second sheet opening) corresponding to the heat dissipation opening 80. The sheet opening 44 is formed to align (match) with the first back panel inner surface opening P. Since the heat dissipation opening 80 does not pass a harness, there is no contact between the harness and the sheet 40, so there is no need to apply special processing to the heat dissipation opening 80. By omitting special processing related to the heat dissipation opening 80, the production efficiency of the part (back panel) can be improved. Furthermore, by not applying special processing to the heat dissipation opening 80, the area of ​​the sheet 40 can be increased, thereby improving noise resistance performance.

[0057] In this embodiment, the sheet 40 is provided on the inner surface of the back panel 3, and the back panel 3 is provided with wiring openings 70 (wiring openings 71 and 72) and heat dissipation openings 80 (see FIG. 4). The housing 1 includes a top panel 2, a back panel 3, a bottom panel 4, a left panel 5, and a right panel 6. However, the sheet 40 may be provided on the inner surface of a panel other than the back panel 3, and the wiring openings 70 (wiring openings 71 and 72) and / or heat dissipation openings 80 may be provided on that panel. In other words, the sheet 40 may be provided on the inner surface of at least one panel, and the wiring openings 70 (wiring openings 71 and 72) and / or heat dissipation openings 80 may be provided on that panel. Furthermore, the wiring openings 70 (with specific processing) and the heat dissipation openings 80 (without specific processing) may be provided on different panels. Furthermore, the wiring openings 71 for the power harness and the wiring openings 72 for the outer end panel harness may be provided on different panels.

[0058] In this embodiment, noise resistance can be further improved by providing the sheet 40 on the inner surface of the side panels (left panel 5 and / or right panel 6) in addition to the inner surface of the back panel 3. Furthermore, noise resistance can be further improved by providing the sheet 40 on the inner surface of the top panel 2 and / or bottom panel 4.

[0059] The top plate 2 has an opening (top plate opening 2a: screw hole shown in FIG. 3) through which a fastener (e.g., a screw) for fixing the cabinet 1 to an island facility in an amusement park is passed (inserted). The fastener is screwed into the top plate opening 2a from the inside of the top plate 2 and fastened (screwed from bottom to top). Inside the cabinet 1, a board unit (e.g., a relay board unit) having a predetermined board (e.g., a relay board) is provided. The board unit includes a board and a case that houses the board, and components (electronic components, connectors, etc.) are arranged on the board surface of the board. The case also has a connector opening for exposing the connector. The board is arranged so that the board surface faces the top plate 2.

[0060] If the sheet 40 is attached to the inner surface of the top plate 2, the sheet 40 may be scraped off when a fastener is inserted into the top plate opening 2a, causing metal powder (dust) to fall downward. If the metal powder falls and enters the board unit (through the connector opening), it may cause a short circuit in the board circuit (causing component failure). Therefore, the inner surface of the housing 1 may be configured so that the sheet 40 is not provided on the inner surface of the top plate 2. In other words, preventing component failure may be prioritized over noise countermeasures. In this case, component failure due to the sheet 40 being scraped off and metal powder falling when the housing 1 is fixed to the island equipment can be prevented.

[0061] In this embodiment, a harness (wiring) is passed through the wiring openings 70 (wiring openings 71 and 72) that have been specially processed. However, the material that is passed through the wiring openings 70 is not limited to wiring, and other materials (conductive materials: game medals, screws, nails, etc.) may also be passed through the wiring openings 70. Furthermore, the wiring openings 70 may be medal supply holes, screw holes, or nail holes. Since the wiring openings 70 have been specially processed, it is possible to prevent the other materials from coming into contact with the sheet 40.

[0062] The gaming machine of this embodiment is A gaming machine equipped with a cabinet (e.g., cabinet 1), The predetermined plates (e.g., back plate 3, bottom plate 4) constituting the outer shape of the housing are provided with a metal sheet (e.g., sheet 40) on the inner side, The predetermined plate has through holes (e.g., small openings 72a, medal supply holes, screw holes, nail holes) for passing conductive members (e.g., wiring, game medals, screws, nails), The sheet has a sheet opening (e.g., sheet opening 42) for passing the conductive member therethrough; The seat opening is larger than the through hole.

[0063] In addition, the gaming machine of this embodiment has A gaming machine equipped with a cabinet (e.g., cabinet 1), A back plate (e.g., back plate 3) that forms the outer shape of the housing has a metal sheet (e.g., sheet 40) on the inner side, the back plate includes a first back plate opening (e.g., wiring opening 72) for routing wiring (e.g., an outer end plate harness); The sheet has a first sheet opening (e.g., sheet opening 42) for passing the wiring through; The first back panel opening has a first back panel inner surface opening (e.g., first back panel inner surface opening G) on the inner surface side of the back panel that is larger than a first back panel outer surface opening (e.g., first back panel outer surface opening F) on the outer surface side of the back panel, The first seat opening is adapted to align with the first back panel inner surface opening.

[0064] If the wiring (conductive member) comes into contact with the metal sheet, the sheet may curl or peel off, which may cause components inside the housing to malfunction. Furthermore, the wiring (conductive member) may be scratched and damaged (such as broken wires). The gaming machine of this embodiment can prevent contact between the wiring (conductive member) and the metal sheet, thereby preventing these problems from occurring. Furthermore, by providing a metal sheet on the inner surface of a specified plate (back plate), noise resistance can be improved. This provides a gaming machine that combines noise suppression and component damage prevention.

[0065] In addition, in the gaming machine of this embodiment, The side plates (e.g., left side plate 5, right side plate 6) that form the outer shape of the housing are provided with the sheet on their inner surfaces, The top plate (e.g., top plate 2) that constitutes the outer shape of the housing does not have the sheet on the inner side, The top plate has a top plate opening (e.g., top plate opening 2a) for passing a fixing tool through, a substrate unit (e.g., a relay substrate unit) having a predetermined substrate (e.g., a relay substrate) is provided inside the housing; The predetermined substrate is disposed so that the substrate surface faces the top plate.

[0066] By providing sheets on the side panels as well, noise resistance can be further improved.Furthermore, by not providing a sheet on the top panel, it is possible to prevent metal powder generated when the chassis is fixed to the island equipment from adhering to the circuit boards inside the chassis and causing component failure.

[0067] In addition, in the gaming machine of this embodiment, the back plate has a second back plate opening (e.g., heat dissipation opening 80) for dissipating heat; the sheet has a second sheet opening (e.g., sheet opening 44) corresponding to the second back panel opening; The second back plate opening is configured such that a second back plate inner surface opening (second back plate inner surface opening P) on the inner surface side of the back plate matches a second back plate outer surface opening (second back plate outer surface opening Q) on the outer surface side of the back plate, The second sheet opening is adapted to align with the second back panel inner surface opening.

[0068] Regarding the heat dissipation holes, by aligning the opening on the inner surface of the back panel with the opening on the outer surface of the back panel, and by aligning the second sheet opening with the opening on the inner surface of the back panel, the area of ​​the sheet can be increased and noise resistance performance can be improved.

[0069] FIG. 10 shows the lower right portion of the inner surface of the back panel 3, which is the rear side of the cashbox 12 (FIG. 3). A pair of conductive rods, a first conductive rod 111 (first sensor) and a second conductive rod 112 (second sensor), are provided on the back panel 3. The first conductive rod 111 and the second conductive rod 112 protrude forward by a predetermined length. The first conductive rod 111 and the second conductive rod 112 are arranged in a vertical line with a predetermined gap between them. Metal fittings (crimp terminals, connection terminals) are connected to the bases of the first conductive rod 111 and the second conductive rod 112, and the metal fittings are connected to a harness (wiring).

[0070] The first conductive rod 111 and the second conductive rod 112 can be housed (enter) inside the cash box 12. As described above, surplus medals are supplied to the cash box 12 from the hopper unit 11. When 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 second conductive rod 112 below. At this point, the first conductive rod 111 and the second conductive rod 112 are not electrically connected.

[0071] Furthermore, when game medals are supplied to the cash box 12, the accumulated game medals come into contact with the first conductive rod 111 above. At this time, the first conductive rod 111 and the second conductive rod 112 are electrically connected. When the first conductive rod 111 and the second conductive rod 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 signal. The main control board sends a command indicating the detection of the error to the sub-control board, and upon receiving the command, the sub-control board notifies the occurrence of the error via the presentation device. This allows an amusement parlor staff member to notice the occurrence of the error and take action to resolve the error.

[0072] In this embodiment, the area around the first conductive rod 111 and the second conductive rod 112 on the back plate 3 is a recess 120. The recess 120 is a vertically long, approximately rectangular shape, and is recessed rearward by a predetermined length (for example, about 5 mm). No special processing (counterboring) has been performed on the recess 120. Here, the opening of the recess 120 on the inner surface side of the back plate 3 is referred to as an inner surface opening T.

[0073] The sheet 40 has a sheet opening 45 (fourth sheet opening) corresponding to the recess 120. The sheet opening 45 is formed to align with the inner surface opening T. As a result, the sheet 40 is not provided inside the recess 120 (bottom and side surfaces), and the material (e.g., wood) that constitutes the back panel 3 is exposed inside the recess 120.

[0074] (Variation) In this embodiment, a metal sheet 40 is attached to the inner surface of a wooden plate (e.g., back plate 3), and special processing is applied to the wiring openings 70 (wiring openings 71 and 72). In this modified example, at least one plate (back plate 3) constituting the housing 1 is made of metal, and the sheet 40 is not attached to the inner surface of the plate. By making at least one plate (back plate 3) of the housing 1 out of metal, noise resistance can be improved (even without the sheet 40). The metal back plate 3 has a wiring opening for a power harness (or an outer end plate harness). Because the wiring opening is an opening (hole) in a metal plate, there is a high possibility that the harness will be damaged if it comes into contact with the opening. No special processing is applied to the wiring opening in this modified example. In this modified example, instead of special processing, a rubber (non-conductive material) ring is attached to the wiring opening. The annular rubber ring is fitted to cover the entire circumference of the wiring opening, and the harness passes through the inside of the ring. Therefore, the harness may come into contact with the rubber ring, but does not come into contact with (the opening in) the metal back plate 3. This prevents the harness from being damaged (broken). In this modification, heat dissipation openings are provided in the metal plate (for example, the back plate 3), but no rubber rings are attached to the heat dissipation openings through which no wiring passes.

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

[0076] The gaming machine of this embodiment is a gaming machine 101 in which games are played by using gaming value as electronic information without using gaming medals as gaming media, and by consuming or being awarded the gaming value. The gaming machine 101 (FIG. 11) is a so-called Smart Pachi Slot (registered trademark). Unlike conventional slot machines in which physical medals are inserted to play a game and physical medals are paid out when a winning combination is achieved, the gaming machine 101 is a gaming machine (medalless gaming machine) in which gaming value as electronic information is used without using physical medals, and by which gaming value is consumed or awarded as a result of playing. The gaming value in a medal-less gaming machine corresponds to medals, which are the gaming value in a conventional slot machine, and since the gaming value in a medal-less gaming machine can be understood as virtual medals (electronic medals), the gaming value in this embodiment may be referred to as medals (gaming medals). In the following, the number of gaming values ​​may be considered as the number of virtual medals, and the number of gaming values ​​may be expressed as "-- pieces" or "-- pieces."

[0077] FIG. 11 is a perspective view of a gaming machine 101 as seen from the front side. As shown in FIG. 11, the gaming machine 101 of this embodiment includes a box-shaped cabinet 1 that is open on the front side, which faces the player, and a front door (front door) 12 that opens and closes the front opening of the cabinet 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 can each be opened and closed freely relative to the cabinet 11. Note that the front door 12 may be 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 open front side (having a front opening). The housing 1 includes a top panel 2, a back panel 3, a bottom panel 4, and left and right side panels 5, 6. The left side panel 5 is referred to as the left side panel 5, and the right side panel 6 is referred to as the right side panel 6. In this embodiment, the top panel 2, back panel 3, bottom panel 4, left side panel 5, and right side panel 6 are made of wood. However, some of the panels may be made of resin.

[0078] In this embodiment, the surfaces of the top panel 2, back panel 3, bottom panel 4, left panel 5, and right panel 6 facing inward of the housing 1 are called "inner surfaces." The bottom surface of the top panel 2, the front surface of the back panel 3, the top surface of the bottom panel 4, the right surface of the left panel 5, and the left surface of the right panel 6 are also "inner surfaces."

[0079] In this embodiment, the surfaces of the top panel 2, back panel 3, bottom panel 4, left panel 5, and right panel 6 that face outward from the housing 1 are called "external surfaces." The top surface of the top panel 2, the back surface of the back panel 3, the bottom surface of the bottom panel 4, the left surface of the left panel 5, and the right surface of the right panel 6 are "external surfaces."

[0080] Inside the cabinet 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] A liquid crystal display 13 (display means) serving as a presentation device is provided in approximately the center of the upper door 12a. The liquid crystal display 13 displays various images (presentation images) to assist and enhance the game. The lower door 12b is provided with a speaker 14 (sound output means) serving as a presentation device. The speaker 14 outputs various presentation sounds (music, sound effects, voice, etc.) to assist and enhance the game. The front door 12 is also provided with lamps 38 (lighting device, lighting means, peripheral lamps) for providing notifications, presentations, etc. Note that a movable accessory that can be operated by an actuator, etc., may also be provided as a presentation device.

[0082] The upper door 12a is provided with a display window 16. A reel unit is arranged behind the display window 16 (first display area 13a, which will be described later) so that a portion of the reel unit can be seen through the display window 16. The outer periphery of each of the reels 15a to 15c is divided 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 line on the outer periphery of each of the reels 15a to 15c. When each of the reels 15a to 15c stops, three symbols (top, middle, and bottom symbols) are displayed per reel through the display window 16. The display window 16 is provided with an upper, middle, and bottom display positions for viewing the symbols on each of the reels 15a to 15c, and a winning line is set by combining the display positions of the reels 15a to 15c. In this embodiment, an active line is formed by the top row of the first reel 15a, the middle row of the second reel 15b, and the bottom row of the third reel 15c.

[0083] In this embodiment, the number of game values ​​required for one game (prescribed number, prescribed number of coins) is set to three, and when the prescribed number of game values ​​is inserted, an active line is activated. When a game starts, each of the reels 15a to 15c starts to spin, and an internal lottery is executed to determine whether any of the winning combinations will be a win or a miss (non-win). Next, when the reels 15a to 15c stop, if a symbol combination corresponding to the winning combination selected by the internal lottery is displayed on the active line, this winning combination will be a win, and a process (a prize-winning process) corresponding to the winning combination will be executed. That is, when the reels 15a to 15c stop, the symbol combination displayed through the display window 16 indicates whether or not the winning combination has been selected. The active line can be said to be a line for determining whether or not a winning combination has been selected.

[0084] The lower door 12b (the operation unit installation stand) is provided with a bet button 35 which is operated when betting (depositing) game value, a start lever 32 (game start operation means) which is operated when starting a game, a stop button 33 (stop operation means) (stop buttons 33a, 33b, 33c) which is operated when stopping the spinning reels, and an effect button 36 (effect operation means) which is operated when progressing the effect, etc. In addition, the bet buttons 35 may be provided as a MAX bet button (first bet button) that is operated when betting three coins (the specified number) of gaming value, and a 1 bet button (second bet button) that is operated when betting one coin of gaming value.

[0085] The effect button 36 is operated when progressing an effect (changing the mode of the effect), etc. The effect button 36 is configured to be pressable, and when pressed, the mode of the effect image displayed on the liquid crystal display 13, for example, changes. By providing the effect button 36 and enabling its operation at a predetermined timing, it is possible to heighten the player's sense of participation in the game and increase the player's interest in the game. For example, the effect button 36 becomes operable during the execution of an effect that gives the player hope of transitioning to an advantageous state, and an image instructing the player to perform 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 the game will transition to an advantageous state) is notified. Note that the effect button 36 is not limited to a button-shaped button, but may be a lever-shaped button or the like, as long as it is configured to be able to detect the player's operation.

[0086] In addition, a door key cylinder 66 is provided on the lower door 12b. The lower door 12b (front door 12) can be unlocked by inserting a door key into the door key cylinder 66. Specifically, the lower door 12b can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from its initial position. Note that an error may also be cleared by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from its initial position.

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

[0088] Although not shown in the figure, a dedicated unit (game value lending device, game medal lending device) as a device for lending game value is provided on the side (right side) of the gaming machine 101. In addition, on the front side of the dedicated unit, there are provided a bill insertion slot into which bills can be inserted, a card insertion / ejection slot into which cards (game value management media) can be inserted / ejected, a lending button (lending operation means), a replay button (lending operation means), a card return button, etc.

[0089] In the dedicated unit, an operation (pressing operation) on the lending button is accepted as a lending operation (game value transfer operation) for transferring game value to the gaming machine 101. When the lending button is pressed, a predetermined number (for example, 50 coins) of game value is credited to the gaming machine 101 by consuming a stored value stored as a prepaid balance on a bill inserted into a bill insertion slot or a card. In addition, in the dedicated unit, an operation (pressing operation) on the replay button is accepted as a lending operation (game value transfer operation) for transferring game value to the gaming machine 101. When the replay button is pressed, game value owned by the player and managed by a card (game value linked to the card) is consumed by consuming a predetermined number (for example, 50 coins) of game value. In this embodiment, an operation on the lending button or replay button as a lending operation means is accepted as a lending operation (game value transfer operation), and based on the lending operation, a predetermined amount of game value is transferred (lent) from the dedicated unit to the gaming machine 101.

[0090] The lower door 12b is provided with a gaming medal count display device 211 (game value number display device, gaming value number indicator), a count button 212, and a settlement button 218. The gaming medal number display device 211 and the count button 212 are provided on the side (right side) of the lower door 12b. Based on the lending operation using the dedicated unit 200, in the gaming machine 101, a value equivalent to a predetermined number of gaming values ​​is set in credits (a gaming value number storage area). The stored value in the gaming value number storage area can also be referred to as the number of credits (reserved number, possessed number). The number of credits (the number of gaming medals available for play) is displayed on the gaming medal number display device 211. The gaming medal number display device 211 has a 5-digit (or 6-digit) 7-segment display, and the number of credits is displayed by this 7-segment display. Note that in the gaming machine 101, the upper limit of the number of credits may be set, for example, within the range of values ​​that can be displayed on the gaming medal number display device 211. In the gaming machine 101, when the bet button 35 is operated in a state where the gaming value is stored as credit, the gaming value stored as credit is set to an inserted state up to a 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 number of credits by a predetermined number when a predetermined role (minor role) is won and a predetermined number of game values ​​is awarded. Furthermore, when an operation to insert game values ​​(operation of the bet button 35) is performed at the start of a game, the game value number control board decreases the number of credits by the number of game values ​​inserted. The game medal number display device 211 displays a value obtained by subtracting the number of bets from the number of possessed medals (number of credits).

[0092] The game value number control board also controls the reception of game values ​​transferred from the dedicated unit to the game machine 101. When game values ​​are transferred from the dedicated unit to the game machine 101, the game value number control board increases the number of credits by the amount of game values ​​transferred. The game value number control board also controls the transfer of game values ​​from the game machine 101 to the dedicated unit. When game values ​​are transferred from the game machine 101 to the dedicated unit, the game value number control board decreases the number of credits by the amount of game values ​​transferred. The game value number control board also displays the number of game values ​​(number of credits) stored in credits on the game medal number display device 211, and changes the display content of the game medal number display device 211 according to the increase or decrease in the number of credits.

[0093] The counting button 212 is a button that is operated when transmitting (returning, transferring) information (credits) indicating a value equivalent to a predetermined number of credits (all or part of the number of credits) to the dedicated unit. The counting button 212 has a pressing portion (operation portion) that is formed to be pressable. When the player ends a game, for example, the credited game value can be transferred from the gaming machine 101 to the dedicated unit based on an operation (pressing operation) on the counting button 212 as a counting operation (returning operation). Then, when an operation (pressing operation) is performed on the card return button after the game value has been transferred to the dedicated unit, a card that allows the number of game value owned by the player to be known is ejected from the dedicated unit (card insertion / ejection slot).

[0094] A predetermined number of gaming values ​​(game medals) are provided to the gaming machine 101 based on the lending operation of the dedicated unit (the number of credits is added). Next, when the bet button 35 is operated, the gaming values ​​are set to a deposit state up to a predetermined number, and a value corresponding to the number of gaming values ​​(number of gaming medals) set to the deposit state is subtracted from the number of credits. In other words, the number of gaming values ​​displayed on the gaming medal number display device 211 decreases. When the predetermined number of gaming values ​​is set to the deposit state, operation of the start lever 32 becomes valid, i.e., a state in which a game can be started. Next, when a game start operation is performed on the activated start lever 32, rotation of each of the reels 15a to 15c begins. Next, when the rotation speed of the reels increases to a predetermined speed and reaches a steady rotation state, operation of the stop buttons 33a to 33c becomes valid. Next, when the activated stop buttons 33a to 33c are operated, the rotation of the corresponding reel stops. Next, when all the reels 33a to 33c have stopped spinning, a process of awarding a predetermined amount of game value (adding it to the credits) or a process of making it possible to restart the game without consuming new game value (replay process) is performed depending on the result of the game, and one game (one game) is ended. Also, when the counting button 212 is operated, a predetermined number of credits (game medals) are sent (returned) to the dedicated unit. Then, when a card return operation is performed in the dedicated unit, a card on which predetermined information is stored is discharged from the dedicated unit 200.

[0095] When the settlement button 218 is operated (pressed) in a state in which game value is set to a deposited state (bet) in the gaming machine 101, the deposited game value is returned to credits. The settlement button 218 is a button that is operated when returning game value that has been deposited (set to a deposited state) by operating the bet button 35 to credits (game value number storage area). In other words, a process (deposit return process) is executed in which the game value that has been set to a deposited state is returned to credits based on the operation of the settlement button 218. The deposit return process is a process in which the setting of the deposited state of the game value is canceled and a value equivalent to the number of game value that was set to the deposited state is added to the number of credits (the value stored in the game value number storage area). When the settlement button 218 is operated in a state in which game value that has been set to a deposited state exists, the game value is returned (returned) to credits based on this operation, and the number of game medals displayed on the game medal number display device 211 increases.

[0096] The main control board is provided with a setting change key cylinder, a setting change button, etc. The setting change key cylinder and the setting change button may be provided in other parts, such as a power supply unit. The setting change key cylinder (setting key switch) has two states: OFF and ON. In other words, it is switchable between the OFF and ON states. The setting change key cylinder is formed so that a setting key can be inserted. The setting change key cylinder is initially in the OFF 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 from the position where the state of the setting change key cylinder is ON to the initial position, the state switches from the ON state to the OFF state. The setting change button can also be pressed.

[0097] The main control board receives input signals from input means such as the bet button 35, start lever 32, and stop buttons 33a to 33c, performs various calculations to execute 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 performance button 36, performs various calculations to execute the performance, and controls the performance devices such as the LCD display 13 and speaker 14 based on the results of the calculations.

[0099] The main control board and the sub-control board are electrically connected, and various information (signals), such as information indicating the game status, can be sent from the main control board to the sub-control board, but information cannot be sent from the sub-control board to the main control board. 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, or by software consisting of a predetermined program pre-stored in ROM, etc.

[0100] Conventional slot machines are equipped with a medal slot, a tray, a hopper unit, a cash box, etc., but the gaming machine 101 does not have any of these.

[0101] FIG. 12 is a perspective view showing the inside of the housing 1. Inside the housing 1, a power supply unit 210 is arranged, which has a built-in power supply board (power supply means) for supplying power to each component. The power supply unit 210 is in the shape of a roughly rectangular parallelepiped box, and is arranged at the lower left inside the housing 1 (placed on the bottom plate 4). The power supply unit 210 is equipped with a power switch (not shown), and when the power switch is turned on, power is supplied from the power supply unit 210 to each component. Note that some components may be configured to receive power even when the power supply unit 210 is turned off. Although not shown, a power cable (power harness) that is connected to an outlet that supplies commercial power (AC 100V) is connected to a power connector provided on the power supply unit 210. Specifically, a connector provided on one end of the power harness is connected to the power connector, and a plug provided on the other end of the power harness is connected to the outlet. The power supply board of the power supply unit 210 creates a DC power supply (for example, 5V, 12V, 24V, etc.) from power sent from outside the gaming machine via a power harness, and supplies power to each component of the gaming machine.

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

[0103] In the gaming machine of this embodiment, as in the gaming machine of the first embodiment, a metal sheet 40 is attached to the inner surface of the cabinet 1 (for example, the back panel 3). The board on which the sheet 40 is attached (hereinafter referred to as the back panel 3) is provided with a wiring opening 70 (first back panel opening) and a heat dissipation opening 80 (second back panel opening). The wiring opening 70 includes 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 gaming ball etc. dispensing device connection terminal board 220.

[0104] The wiring opening 70 through which the harness passes is subjected to a special processing (for example, countersunk processing), but the heat dissipation opening 80 through which the harness does not pass is not subjected to a special processing (for example, countersunk processing). The opening on the inner surface side of the first back plate of the wiring opening 70 is larger (in diameter) than the opening on the outer surface side of the first back plate. The opening on the inner surface side of the back plate 3 (housing 1) of the wiring opening 70 is larger than the opening on the outer surface side of the back plate 3.

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

[0106] By aligning the sheet opening (first sheet opening) corresponding to the wiring opening 70 (wiring opening 72 in FIG. 6 ) with the first back panel inner surface opening (first back panel inner surface opening G in FIG. 6 ) (by shifting the position of the edge of the sheet 40 outward), it is possible to prevent the harness from coming into contact with the sheet 40. Preventing the harness from coming into contact with the sheet 40 provides the following advantages: (1) If the harness comes into contact with the sheet 40, problems such as the edge of the sheet 40 curling up, a portion of the sheet 40 peeling off (torn), and the peeled-off sheet 40 coming into contact with a circuit board inside the housing 1, causing a short circuit (component failure), can be prevented. (2) If the harness comes into contact (rubbed) with the edge (edge) of the sheet 40, the harness can be damaged (the harness coating can be torn), potentially resulting in a disconnection, can be prevented. Furthermore, even if the covering of the harness is peeled off and the conductor is exposed, it is possible to reduce the possibility that the conductor will come into contact (become electrically conductive) with the sheet 40. According to this embodiment, it is possible to provide a gaming machine that combines the noise suppression effect of the sheet 40 and the component damage (failure) suppression effect of the specific processing.

[0107] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. Furthermore, within the scope of the present invention, the embodiments can be freely combined, or any of the components of each embodiment can be modified, or any of the components can be omitted from each embodiment. For example, the configuration of the slot machine is not limited to that of the above-described embodiments. Furthermore, the above-described configuration can be applied not only to slot machines, but also to other gaming machines. [Explanation of symbols]
