Description

  The present invention relates to a gaming machine such as a slot machine.

  As a gaming machine of this type, for example, in a slot machine, a reel device, a medal payout device, various control devices including a main board, a power supply device, etc. are mounted inside a box-shaped housing, and can be opened and closed on the front side of the housing. The front door to be attached is provided with a medal insertion device, a start lever, a stop button, and the like. The reel device is provided with a plurality of reels having a plurality of symbols on the outer peripheral surface, and a part of the symbols can be visually recognized through the display window of the front door. Then, when the player inserts a medal and operates the start lever, each reel starts to rotate, and accordingly, the symbols attached to the outer peripheral surface of each reel are variably displayed through the display window. Thereafter, the reels are stopped by operating the stop switch after the reels start rotating. In addition, when all reels are stopped, a predetermined number of medals are paid out according to a combination of symbols formed on a preset active line, or a special game such as a bonus game advantageous to the player. Benefits such as shifting to a state are granted.

  In a gaming machine in which various devices are mounted inside a box-shaped casing as described above, for example, when power is supplied to a reel device or various control devices, heat is generated from the power supply device, and the temperature inside the power supply device is reduced. May rise. Therefore, a vent hole is formed on the upper surface of the power supply device, and heat generated from the power supply device can be released to the outside of the slot machine or external air can be taken into the power supply device on the rear side of the housing. In general, an opening is formed (see, for example, Patent Document 1).

However, the present inventors have come to be concerned that the above configuration cannot sufficiently suppress the temperature rise in the power supply device. That is, since the heated air rises, the heat generated in the power supply device is more likely to be released from the vent hole on the upper surface of the power supply device than from the opening. Therefore, when considering a flow in which air outside the housing is taken into the power supply device from the opening and the heated air in the power supply device is released from the vent hole, for example, convection in the lower part of the power supply device is caused. This is because there is a possibility that heat will be trapped in the place where it does not occur.

Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Based on the number of pulses from when the detection signal of the reel index sensor 55 is output, it is recognized which symbols are visible from the display windows 31L, 31M, and 31R, and arbitrary symbols are displayed on the display window. Control to make it visible from 31L, 31M, 31R can be performed.

  Of the symbols attached to the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly determined by the vertical lengths of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 8 shows a symbol array drawn on the belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each of the reels 42L, 42M, and 42R is provided with 21 symbols in a row. In addition, numbers 0 to 20 are assigned to the reels 42L, 42M, and 42R, and these numbers are used for the main controller 131 to recognize the symbols that are visible from the display window. It is a number and is not actually attached to the reels 42L, 42M, 42R. However, in the following description, the number is used for explanation.

  The symbols include “Replay” symbol (for example, left belt 20th), “Bell” symbol (for example, left belt 19th), “Youth” symbol (for example, left belt 18th), “7” symbol (for example, (Left belt 17th), “Cherry” design (eg, left belt 13th), “Chance” design (eg, left belt 12th), “Watermelon” design (eg, left belt 9th), “Reach” design ( For example, there are nine types: the 6th left belt) and the “Lucky” symbol (for example, 1st left belt). As shown in FIG. 8, the number of various symbols and the arrangement order of the belts wound around the reels 42L, 42M, and 42R are completely different.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of variable display means for variably displaying identification information, and constitutes a main display unit. However, the variable display means may have a configuration other than this as long as the symbol is variably displayed in the circumferential direction. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used. In addition to the mechanical reel configuration, an electric display such as a liquid crystal display or a dot matrix display may be used. A device for variably displaying the identification information may be provided, and in this case, it is possible to give abundant variations in the display form.

  A total of five combination lines are attached to the game panel 30 such that three display windows 31L, 31M, and 31R are connected to each other and three in parallel in the horizontal direction and two in diagonal directions. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to these combination lines, effective line display sections 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (middle line) of the combination lines is activated. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. And, when the combination line that has been activated, that is, when the symbol is stopped in a predetermined combination on the activated line, a prize is awarded, and a payout process for a predetermined medal number or a bonus game such as a BB game that is in a special gaming state is awarded. Migration processing etc. are executed.

  FIG. 9 shows a combination of symbols for winning and the number of medals to be paid out when winning.

  Small prizes for which medals are paid out include a watermelon prize, a bell prize, and a cherry prize. When stopped alongside the “Watermelon” symbol, “Watermelon” symbol, and “Watermelon” symbol from the left on the active line, 15 medals are paid out as a watermelon prize, “Bell” symbol from the left, “Bell” on the active line In the case of stopping alongside the symbol and the “bell” symbol, eleven medals are paid out as a bell prize. When the “cherry” symbol on the left reel 42L stops on the active line, two medals are paid out as a cherry prize. That is, in the case of a cherry winning, any symbol that stops on the active line of the middle reel 42M and the right reel 42R may be any symbol. Therefore, when the “cherry” symbol stops at the position where the plurality of effective lines of the left reel 42L overlap (specifically, the upper stage or the lower stage), a cherry winning is established on each active line, and the overlapping effective The medal is paid out by multiplying the number of lines. As a result, in this embodiment, four medals are paid out.

  Further, there is a BB winning as a state transition winning in which the gaming state shifts. When the “7” symbol, “7” symbol, and “7” symbol are stopped from the left on the active line, the game state shifts to the BB game where the gaming state is the special gaming state as a BB winning. However, even if the “7” symbol stops along the left, middle and right on the active line, no medal is paid out. That is, when the combination of the “7” symbols is established on the active line, only the BB game is entered. In other words, it can be said that the “7” symbol is a state transition symbol for shifting the gaming state to the BB game.

  Furthermore, when the “replay” symbol, “replay” symbol, and “replay” symbol are stopped from the left on the active line, a re-game win is awarded. When the re-game winning is established, the medal payout and the state transition are not performed, but the player can play the next game without reducing the medals owned and without inserting medals.

  In addition, only when the gaming state is an RB game, when the game is stopped along with the “Replay”, “Replay”, and “Chance” symbols from the left on the active line, and “Replay” from the left on the active line. In the case of stopping alongside the symbol “replay” symbol and “lucky” symbol, 15 medals are paid out as a JAC prize.

  In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the combination of the symbols described above does not stop on the active line, the medal payout, the transition of the gaming state, etc. Not done at all. That is, the “chance” symbol and “lucky” symbol of the left reel 42L, the “cherry” symbol of the middle reel 42M and the right reel 42R, the “young” symbol and the “reach” symbol of each reel 42L, 42M, 42R Not involved at all. In other words, it can be said that each of the symbols is a no-benefits symbol unrelated to the privilege given to the player. As described above, each of the reels 42L, 42M, and 42R is provided with a bonus symbol related to winning such as a “bell” symbol and a non-privileged symbol irrelevant to winning such as a “young” symbol, for example. In the following, a combination of symbols corresponding to each prize is also referred to as a combination of winning symbols. For example, the BB symbol combination is a symbol BB winning combination, that is, a combination of “7” symbol, “7” symbol, and “7” symbol.

  On the lower left side of the game panel 30, a start lever 71 is provided that is operated to start rotation of the reels 42L, 42M, and 42R all at once (not necessarily simultaneously).

The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the original position after the hand is released. When the start lever 71 is operated when a predetermined number of medals are inserted, the reels 42L, 42M, and 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. Each of the stop switches 72, 73, 74 is arranged directly below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. That is, when the left stop switch 72 is operated, the rotation of the left reel 42L is stopped. When the middle stop switch 73 is operated, the rotation of the middle reel 42M is stopped and the right stop switch 74 is operated. In this case, the rotation of the right reel 42R is stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop the variable display of symbols based on the rotation of the reels 42L, 42M, 42R. Each of the stop switches 72, 73, 74 can be stopped when a predetermined time elapses after the left reel 42L starts rotating, and is stopped by lighting a lamp (not shown) during such a state. It is notified that the operation is possible, and is turned off when the rotation stops.

  On the lower right side of the display windows 31L, 31M, 31R, there is provided a medal slot 75 for inserting a medal as an investment value. The medal slot 75 constitutes an input means for inputting the investment value. Further, if attention is paid to the point that the medal insertion slot 75 is accompanied by the operation of directly inserting the medal by the player, it can be said that the medal insertion slot 75 constitutes a direct input means for directly inputting the investment value.

  The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 as passage switching means provided on the back surface of the front door 12. That is, the selector 84 is provided with a medal path switching solenoid 83, which is set to the discharge path 82 side when the medal path switching solenoid 83 is not excited, and switched to the storage path 81 side when excited. The medal guided to the storage passage 81 is guided to the hopper device 91 housed in the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  A hopper device 91 as a payout means for giving a medal to a player is composed of a storage tank 92 for storing the medal and a payout device 93 for paying out the medal to the player. The payout device 93 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 94 provided in the central right part of the discharge passage 82 and to the medal tray 18 through the discharge passage 82. To come out. Further, a reserve tank 95 is provided on the right side of the hopper device 91 in order to avoid storing a predetermined amount or more of medals in the storage tank 92. A guide plate 96 for discharging medals from the storage tank 92 to the reserve tank 95 is provided inside the storage tank 92 of the hopper device 91. Therefore, when medals are stored more than the height at which the guide plate 96 is provided, the medals are stored in the reserve tank 95.

When this switch is pressed, the selector 84 is mechanically operated to operate the selector 84. The medals packed in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, 31R, there is provided a button-like first credit insertion switch 77 for inserting three virtual medals credited as investment values at a time. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal. Each of the credit insertion switches 77 to 79, together with the medal insertion slot 75, constitutes an input means for inputting an investment value. Further, if the medal insertion slot 75 is accompanied by an operation of directly inserting a medal by the player, each credit insertion switch 77 to 79 is only accompanied by an operation of inserting a virtual medal based on the storage memory. It can also be said that it constitutes an indirect input means for indirectly inputting the investment value.

  The first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) to urge that the maximum number of medals that can be inserted per game (three) has not been reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77. However, when there is no credited virtual medal or three medals have already been inserted. It is turned off under the circumstances. Here, instead of the above-described lighting, the player may make it easier to understand the prompt for medal insertion by blinking.

  A button-like settlement switch 80 is provided on the left side of the start lever 71. That is, the slot machine 10 has a credit function for storing and storing surplus inserted medals up to a predetermined maximum value (for 50 medals) and winning medals as virtual medals. The virtual medal is paid out as an actual medal when the settlement switch 80 is pressed while stored and stored. In this case, if paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the checkout switch 80 constitutes a checkout operation means for actually paying out the stored game value.

May be added. In this case, the settlement switch (changeover switch) 80 is turned on when pressed once, turned off when pressed again, and switched on / off every time a pressing operation is performed. When the settlement switch 80 is on, the credit mode is selected. When the settlement switch 80 is off, the direct mode is selected. If there are virtual medals when the credit mode is switched to the direct mode, the virtual medals corresponding to the virtual medals are paid out as real medals. Thereby, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The settlement switch 80 constitutes a switching operation means for switching the input value and game value handling formats.

  Below the display windows 31L, 31M, and 31R of the game panel 30, a credit display unit 35 that displays the number of virtual medals stored and stored, and the remaining number of acquired medals that displays the number of remaining medals that can be acquired before the BB game is over. A display unit 36 and an acquired number display unit 37 for displaying the number of medals acquired at the time of winning are provided. Although these display parts 35-37 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, a procedure for betting medals will be described. If a medal is inserted from the medal slot 75 at the start of the game, a bet is placed.

  That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display section 32 is turned on, and the corresponding middle line becomes the effective line, and the second medal is the medal insertion slot. When the number 75 is inserted, the second effective line display section 33 is turned on, and a total of three combination lines including the upper line and the lower line corresponding to the second effective line display section 33 become effective lines, respectively, and the third medal is a medal. When it is inserted into the insertion port 75, the third effective line display unit 34 is further turned on, and a total of five combination lines including a pair of diagonal lines corresponding thereto become effective lines.

  When four or more medals are inserted into the medal slot 75, the surplus medals exceeding three are stored inside the slot machine if the number of virtual medals stored and stored at that time is less than 50. At the same time, the number of virtual medals on the credit display unit 35 is added and displayed. On the other hand, when the number of virtual medals is 50 or reaches 50, the selector 84 switches from the storage passage 81 to the discharge passage 82, and the surplus medals are returned from the medal discharge port 17 to the medal tray 18. Is done.

  Further, when the stored number is displayed on the credit display unit 35, a virtual medal is inserted even when any of the first to third credit insertion switches 77 to 79 is pressed, and a bet is made. .

  When the third credit insertion switch 79 is pressed, the numerical value displayed on the credit display unit 35 is decremented by one as a virtual medal is inserted, and the first effective line display unit 32 is turned on. The middle line becomes the active line. When the second credit insertion switch 78 is pressed, two numerical values displayed on the credit display unit 35 as two virtual medals are inserted are subtracted, and the first valid line display unit 32 and the second The effective line display unit 33 is turned on, and a total of three combination lines become effective lines. When the first credit insertion switch 77 is pressed, three numerical values displayed on the credit display unit 35 are subtracted as three virtual medals are inserted, and all the effective line display units 32 to 34 are displayed. Lights up and a total of five combination lines become effective lines.

Has been. Here, the cutout portion 44 of the bottom plate 11 b of the housing 11 is formed to be smaller than the lower surface plate 121 b of the power supply box 121. That is, the front-rear dimension of the notch 44 is smaller than the front-rear dimension of the lower surface plate 121b, and the left-right dimension is smaller than the left-right dimension of the lower surface plate 121b. Each through hole 46 of the back plate 11 c of the housing 11 is formed at a position corresponding to the power supply device 161 and smaller than the rear plate 121 d of the power supply box 121. That is, the horizontal dimension of each through-hole 46 is smaller than the horizontal dimension of the rear plate 121d, and the vertical dimension is smaller than the vertical dimension of the rear plate 121d. Further, in each through hole 46, the distance between the upper side of the upper through hole 46 and the lower side of the lower through hole 46 is smaller than the vertical dimension of the rear plate 121d. Therefore, in a state where the power supply device 161 is installed in the housing 11, as shown in FIG. 3, the opening 45 of the housing 11 is blocked by the power supply device 161, and the opening 45 is formed in the lower surface through hole 125 b of the power supply device 161. It is in a state of communicating with. In addition, each through hole 46 of the housing 11 is closed by the power supply device 161.

  A main controller 131 is attached to the back plate 11 c of the housing 11 above the reel unit 41. The main control device 131 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that temporarily stores necessary data according to the progress of the game, a port that communicates with various devices, time counting and synchronization. A main board including a clock circuit and the like used in the case of planning is provided, and the main board is accommodated in a board box as an encapsulating means made of a transparent resin material or the like. The board box includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other so as not to be opened by a sealing unit as a sealing means, whereby the substrate box is sealed. In addition, it is good also as a structure which connects a box base and a box cover so that opening is impossible using a key member.

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main control device 131 is equipped with a microcomputer centering on a CPU 151 as arithmetic processing means. In addition to the power supply board provided in the power supply device 161, the CPU 151 is connected to a clock circuit 154 that outputs a rectangular wave having a predetermined frequency, an input / output port 155, and the like via an internal bus. The main control device 131 functions as a main base incorporated in the slot machine 10.

  On the input side of the main controller 131, there are a start detection sensor 71a for detecting the operation of the start lever 71, stop detection sensors 72a, 73a, 74a for individually detecting the operations of the stop switches 72, 73, 74, and a medal slot. An inserted medal detection sensor 75a for detecting medals inserted from 75, credit insertion detection sensors 77a, 78a, 79a for individually detecting operations of the respective credit insertion switches 77, 78, 79, and an adjustment for detecting an operation of the adjustment switch 80. Detection sensor 80 a, reel index sensor 55 that individually detects the rotational position (origin position) of each reel 42, payout detection sensor 91 a that detects medals paid out from the hopper device 91, and reset detection sensor that detects the operation of the reset switch 123 123a, set to setting key insertion hole 124 Various sensors such as a setting key detection sensor 124a for detecting that a key is inserted and turned on are connected, and signals from these various sensors are output to the CPU 151 via the input / output port 155. ing.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 81 extending from the medal insertion slot 75 to the hopper device 91 is configured such that medals can pass in one row. The storage passage 81 is provided with a first sensor, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal. The inserted medal detection sensor 75a is constituted by each of the first to third sensors. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, the main control device 131 considers that there has been a medal clogging or fraud and makes an error. If an error occurs, an error notification is performed and an operation by the player until the error is canceled is invalidated. The main controller 131 also monitors the order in which the second sensor and the third sensor are turned on and off, both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. Only when the third sensor is turned on, both the second and third sensors are turned off, and when the time for switching to each on / off switching is within a predetermined time, it is determined that the medal has been normally taken in. Otherwise, an error is assumed. The reason for this is to prevent injustice that the medal is reciprocated in the vicinity of the inserted medal detection sensor 75a and misidentified as the medal inserted in addition to the clogging of the medal in the storage passage 81.

  A power supply device 161 (power supply board) is connected to the input side of the main control device 131 via an input / output port 155. On the power supply board, a power supply unit 161a that supplies driving power to each electronic device of the slot machine 10 including the main control device 131, a power failure monitoring circuit 161b, and the like are mounted.

  The power failure monitoring circuit 161b is for monitoring the power-off state and generating a power failure signal not only at the time of power failure but also at the time of power-off by the power switch 122. For this reason, the power failure monitoring circuit 161b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 161a, and determines that the power supply is shut off when the drive voltage drops below, for example, 10 volts. Power outage signal is output. The power failure signal is supplied to each of the CPU 151 and the input / output port 155, and the CPU 151 recognizes this power failure signal and executes a power failure process. Further, the power failure signal is also supplied to the display control device 111.

  The power supply unit 161a is configured to output a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main control device 131 even when the output voltage is reduced to less than 10 volts. As a time for outputting the stabilization voltage, a time sufficient for executing the power failure process by the main controller 131 is secured.

  On the output side of the main controller 131, each of the effective line display units 32, 33, 34, the credit display unit 35, the remaining acquired number display unit 36, the acquired number display unit 37, and the reels 42L, 42M, 42R is rotated. Stepping motors 61 (61L, 61M, 61R), a medal path switching solenoid 83 provided in the selector 84, a hopper device 91, a display control device 111, an external concentration terminal plate 171 capable of transmitting information to a hall management device (not shown), etc. Are connected via the input / output port 155.

  The display control device 111 is a control device for driving the upper lamp 13, the speaker 14, and the auxiliary display unit 15, and includes a substrate in which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving a signal from the main control device 131, the display control device 111 independently drives and controls the upper lamp 13, the speaker 14, and the auxiliary display unit 15. Therefore, the display control device 111 is a sub-base that executes auxiliary control in relation to the main control device 131 that is a main base that manages and manages games. In other words, the sub-base is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main base. In addition, it is good also as a structure which the display control apparatus 111 controls the various display parts 32-37.

  The CPU 151 described above stores various control programs executed by the CPU 151 and a ROM 152 storing fixed value data, and temporarily stores various data when the control program stored in the ROM 152 is executed. In addition to the RAM 153 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit, as well known, and a credit counter for counting the number of credits are known. Various counters such as are built-in.

  The RAM 153 is configured to hold (back up) data by supplying a backup voltage from a power supply board provided in the power supply device 161 even after the power of the slot machine 10 is cut off. The RAM 153 stores a memory for temporarily storing various data, a setting information storage area 153a used when setting a winning probability, a game state such as a BB game, and various data used during a BB game. In addition to a BB information storage area 153b for playing, a game information storage area 153c for storing various data used in each game, a backup area is provided.

  The backup area is an area for storing the value of the stack pointer when the power is shut down due to the occurrence of a power failure or the like (including power shut down by operating the power switch 122; the same applies hereinafter). Yes, when the power failure is resolved (including power-on by operating the power switch 122; the same applies hereinafter), the state of the slot machine 10 can be restored to the state before power-off based on the backup area information. . Writing to the backup area is executed when the power is cut off by the power failure process, and restoration of each value written to the backup area is executed in the main process when the power is turned on. Note that a power failure signal from the power failure monitoring circuit 161b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 151 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

  Next, the flow of air inside the housing 11 will be briefly described.

  In the power supply device 161, heat is generated from the power supply substrate when power is supplied to various electronic devices including the main control device 131. More specifically, the power supply board is equipped with a power conversion circuit that converts AC power into DC power, a transformer that raises and lowers the voltage, and the switching element of the power conversion circuit as power is supplied to the power supply board. Heat is generated from the coil and transformer coil. When heat is generated from the power supply board, the air in the power supply device 161 is heated. The heated air rises to the upper part of the power supply device 161 and is discharged to the outside of the power supply device 161 from the upper surface through hole 125a or the side through hole 125e of the power supply device 161 that is located relatively higher. Or, the rear surface through hole 125d located at a relatively upper portion is discharged to the outside of the slot machine 10 through the through hole 46 of the housing 11. At this time, the air outside the slot machine 10 is taken into the power supply device 161 from the lower surface through hole 125b of the power supply device 161 through the opening 45 of the housing 11, or is positioned relatively lower in the rear surface through hole 125d. From what is to be taken into the power supply device 161 through the through hole 46 of the housing 11. Therefore, in the power supply device 161, convection of air is generated in which air taken from below the power supply device 161 is released above the power supply device 161.

  Further, the heated air exhausted from the upper surface through-hole 125 a of the power supply device 161 rises to the upper part of the housing 11, and the outside of the slot machine 10 from the through-hole 48 positioned at the upper part of the housing 11. To be discharged. At this time, air outside the slot machine 10 is taken into the housing 11 through the through holes 46 and 47 of the back plate 11 c in addition to the opening 45 of the housing 11. Further, when air outside the slot machine 10 is taken into the housing 11 from the opening 45 or the through hole 46, the air is taken into the power supply device 161. Accordingly, the heated air is discharged from the through-hole 48 or the like to the outside of the housing 11, so that convection of air from the lower portion to the upper portion occurs in the housing 11.

  Here, it is assumed that the slot machine 10 is installed in an island facility of a game arcade. Since the opening 45 of the housing 11 is opened to the rear, left, and lower side of the housing 11, for example, even when the side opened to the lower side of the opening 45 is blocked by the pedestal of the island facility, The rear and left sides are opened. Since the side plate 11d and the back plate 11c are erected on the upper surface of the bottom plate 11b, the vertical dimension of the opening 45 is the same as the thickness dimension of the bottom plate 11b. Since the bottom plate 11b needs to have a strength that can withstand the load of the slot machine 10, etc., the bottom plate 11b has a predetermined thickness that can ensure the strength. Since the bottom plate 11 is a wooden plate shape, the predetermined thickness is relatively thick, and the open area to the rear and left of the opening 45 is relatively large. Therefore, even if the lower portion of the opening 45 is blocked, the air outside the slot machine 10 is taken into the power supply device 161 from the lower surface through hole 125b through the region opened to the rear and left of the opening 45.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  Since the upper surface through-hole 125a is formed in the power supply box 121 of the power supply device 161, when heat is generated from the power supply substrate, the heated air can be discharged from the upper surface through-hole 125a. Moreover, since the lower surface through-hole 125b is formed in the power supply box 121 of the power supply device 161, the air outside the power supply device 161 can be taken in from the lower surface through-hole 125b. The air taken in from the lower surface through hole 125b rises by being heated in the power supply device 161 and is discharged from the upper surface through hole 125a. Therefore, even when heat is generated from the power supply substrate, the heated air can be discharged from the upper surface through hole 125a while air is taken into the power supply device 161 from the lower surface through hole 125b. Thereby, in the power supply device 161, convection of air from the lower side to the upper side of the power supply device 161 can be generated, and heat can be prevented from being accumulated in the power supply device 161. Therefore, it can suppress that the temperature in the power supply device 161 rises.

  For example, when the upper surface through-hole 125a is not formed in the upper surface plate 121a, heat is taken from the rear surface through-hole 125d or the side surface through-hole 125e formed at a relatively upper portion of the power supply device 161 while taking air from the lower surface through-hole 125b. However, there is a concern that the air in the vicinity of the upper surface plate 121a in the power supply device 161 may be trapped and the temperature in the power supply device 161 may increase. Further, when the lower surface through-hole 125b is not formed in the lower surface plate 121b, the heated air is taken in while taking air from the rear surface through-hole 125d or the side surface through-hole 125e formed in the lower part of the power supply device 161. Although it can discharge | emit from the upper surface through-hole 125a, there exists a concern that the air heated up may be near the lower surface board 121b in the power supply device 161, and the temperature in the power supply device 161 may rise. On the other hand, when the upper surface through-hole 125a and the lower surface through-hole 125b are formed in the power supply device 161, air convection from the lower side to the upper side of the power supply device 161 can be generated. It is possible to suppress heat from being accumulated in the vicinity or in the vicinity of the lower surface plate 121b. Therefore, it can suppress that the temperature in the power supply device 161 rises.

  Since the power supply device 161 is installed in contact with the bottom plate 11b of the housing 11 so that the lower surface through hole 125b of the power supply device 161 is positioned above the opening 45 of the housing 11, the lower surface through hole 125b and the opening 45 are communicated. Can be made. Therefore, the air outside the housing 11 can be directly taken into the power supply device 161. For example, when the power supply device 161 is attached to the lower side of the partition plate 40 and the power supply device 161 is arranged away from the bottom plate 11b, if the air inside the housing 11 is heated, the heated air is There is a possibility that the temperature rise in the power supply device 161 cannot be sufficiently suppressed by being taken into the power supply device 161 from the lower surface through hole 125b. On the other hand, when the lower surface through-hole 125b of the power supply device 161 and the opening 45 of the housing 11 communicate with each other, even if the air inside the housing 11 is heated, the air outside the housing 11 is Since it can take in directly into the power supply device 161 from the through-hole 125b, it can suppress that the temperature in the power supply device 161 rises.

  In addition to vertically passing through the bottom plate 11 b of the housing 11, the housing 11 is provided with an opening 45 that opens to the rear and left of the housing 11. In addition, the air outside the housing 11 can be taken into the power supply device 161 from the rear and the left side of the housing 11 through the lower surface through hole 125b. Therefore, for example, when the slot machine 10 is installed in an island facility of a game arcade, even if the lower part of the opening 45 of the housing 11 is blocked by a pedestal or the like of the island facility, the rear and left sides of the housing 11 Thus, air outside the housing 11 can be taken in from the power supply 161 to generate air convection from the lower side to the upper side. For this reason, it is possible to suppress heat from being accumulated in the power supply device 161 and to suppress a temperature rise in the power supply device 161. Further, when the slot machine 10 is installed in the island facility of the game hall, the lower portion of the opening 45 of the housing 11 is blocked by a pedestal of the island facility, and the opening 45 of the housing 11 is closed by a medal lending device or the like. Even if the left side is blocked, air outside the housing 11 can be taken from behind the opening 45 to generate convection of air from the lower side to the upper side of the power supply device 161. For this reason, it is possible to suppress heat from being accumulated in the power supply device 161 and to suppress a temperature rise in the power supply device 161.

  Since the opening 45 of the housing 11 is closed by the lower surface plate 121b of the power supply device 161 and each through hole 46 formed in the lower left portion of the back plate 11c of the housing 11 is closed by the rear surface plate 121d of the power supply device 161, Even if the opening 45 and each through-hole 46 are formed in the body 11, it is possible to exert a deterrent effect against fraud performed inside the housing 11. When the opening 45 and each through hole 46 are not blocked by the power supply device 161, a hand or a tool is inserted into the housing 11 from the opening 45 or each through hole 46. There is a risk of installation. When a fraudulent board is installed, a fraud signal output from the fraudulent board is input to the main control device 131, so that the winning probability of the slot machine 10 is illegally set, and the fraudster gains a profit illegally. There is a possibility that. Therefore, the fraud can be suppressed by closing the opening 45 and each through hole 46 of the housing 11 with the power supply device 161. Therefore, it is possible to achieve a deterrent effect against fraud performed inside the housing 11 while suppressing heat accumulation in the power supply device 161.

  Since a plurality of lower surface through holes 125b are formed in the lower surface plate 121b of the power supply device 161 so as to be aligned in the front-rear and left-right directions, a large area for allowing air to pass through can be secured in the lower surface plate 121b. As a result, air outside the housing 11 can be easily taken into the power supply device 161, and air convection from below to above the power supply device 161 can be easily generated. For this reason, it is possible to more suitably suppress heat from being accumulated in the power supply device 161. Certainly, if a through hole is formed in the lower surface plate 121b so that the opening 45 of the housing 11 is not covered by the lower surface plate 121b of the power supply device 161, a large area for allowing air to pass through in the lower surface plate 121b should be secured. Therefore, the air outside the housing 11 can be easily taken into the power supply device 161. However, when a through hole is formed in the lower surface plate 121b so that the opening 45 of the housing 11 is not covered by the lower surface plate 121b of the power supply device 161, a hand or a tool is inserted into the power supply device 161 from the through hole to turn on the power. There is a concern that fraud such as illegal blocking will be performed. Therefore, in the present embodiment, a plurality of lower surface through holes 125b are formed in the lower surface plate 121b of the power supply device 161 so as to be aligned in the front-rear and left-right directions. Thereby, in the lower surface plate 121b, it is possible to subdivide a region for allowing air to pass through, and to reduce each of the lower surface through holes 125b. Therefore, it is possible to prevent a hand or a tool from being inserted from the lower surface through hole 125b while ensuring a large area for allowing air to pass through the lower surface plate 121b. Therefore, it is possible to suppress fraud in the power supply device 161 and the like while suppressing the temperature inside the power supply device 161 from rising.

  Since the through hole 48 is formed in the upper part of the back plate 11c of the housing 11, when the heated air is discharged from the upper surface through hole 125a of the power supply device 161, the heated air is removed from the through hole 48. Can be discharged. Moreover, since the through-hole 47 is formed in the lower part of the back plate 11c of the housing | casing 11, the air outside the housing | casing 11 can be taken in from the through-hole 47 formed in the lower part of the back plate 11c of the housing | casing 11. For this reason, even if heated air is discharged from the power supply device 161 into the housing 11, the heated air is drawn into the housing 11 through the through holes 47 at the bottom of the housing 11. It can be discharged from the through hole 48 at the top of the housing 11 to the outside of the housing 11. Thereby, it is possible to suppress not only the temperature in the power supply device 161 but also the temperature in the housing 11 from rising.

  Further, since the through-hole 48 is formed in the upper portion of the back plate 11c of the housing 11, the heated air is discharged to the outside of the housing 11 while suppressing dust and the like from entering the housing 11. Can do. For example, when a through-hole penetrating in the vertical direction is formed in the top plate 11a of the housing 11, dust or the like may enter the inside of the housing 11 from the through-hole. In this case, in order to suppress the entry of dust into the housing 11, it is necessary to provide a dust cover or the like in the through hole of the top plate 11a. On the other hand, when the through hole 48 is formed in the back plate 11c, the intrusion of dust into the housing 11 can be suppressed without providing a dust cover or the like in the through hole 48. Therefore, by forming the through hole 48 in the upper part of the back plate 11c of the housing 11, it is possible to suppress the intrusion of dust into the housing 11 with a relatively simple configuration in which a dustproof cover or the like is not provided in the through hole 48. However, the heated air can be discharged to the outside of the housing 11.

  Since a plurality of side surface through holes 125e are formed in the side surface plate 121e of the power supply device 161 so as to align not only in the front-rear direction but also in the vertical direction, the side surface through holes formed not only from the lower surface through hole 125b but also in the lower part of the side plate 121e. Air can also be taken into the power supply device 161 from 125e. As a result, more air can be taken into the power supply device 161. In addition, when excessive heat is generated from the power supply substrate, not only the upper surface through hole 125a but also the heated air from the side surface through hole 125e formed at the upper portion of the side plate 121e to the outside of the power supply device 161. Can be discharged. Furthermore, air can be taken not only from the lower side of the power supply device 161 but also from the right side of the power supply device 161, and the air can be discharged not only to the upper side of the power supply device 161 but also to the right side of the power supply device 161. A plurality of directions of air convection can be generated in the power supply device 161. Thereby, it is possible to suppress heat from being accumulated in the corners in the power supply device 161. As a result, the temperature in the power supply device 161 can be prevented from rising.

  A plurality of rear through-holes 125d are formed in the rear plate 121d of the power supply device 161 so as to be aligned not only in the left-right direction but also in the vertical direction, and rearwardly in front of the through-hole 46 formed in the lower left portion of the back plate 11c of the housing 11. Since the rear plate 121d of the power supply device 161 is placed in contact with the back plate 11c of the housing 11 so that the face plate 121d is positioned, the rear surface through hole 125d of the power supply device 161 and the through hole 46 of the housing 11 communicate with each other. Can be made. Therefore, the air outside the housing 11 can be directly taken into the power supply device 161 not only from the lower surface through hole 125b but also from the rear surface through hole 125d formed in the lower part of the rear surface plate 121d. Thereby, more air outside the housing 11 can be taken into the power supply device 161. Therefore, it can suppress that the temperature in the power supply device 161 rises. In addition, when excessive heat is generated from the power supply board, in addition to the upper surface through hole 125a and the side surface through hole 125e formed in the upper portion of the side plate 121e, the rear surface through hole 125d formed in the upper portion of the rear surface plate 121d. Heated air can be discharged to the outside of the power supply device 161. Furthermore, since the rear surface through hole 125d of the power supply device 161 and the through hole 46 of the housing 11 communicate with each other, air heated from the rear surface through hole 125d formed in the upper portion of the rear surface plate 121d Can be discharged directly. Thereby, the air discharged | emitted from the power supply device 161 into the inside of the housing | casing 11 can be reduced among the air which has the heat discharged from the power supply device 161. FIG. Therefore, it can suppress that the temperature in the power supply device 161 rises, and can also suppress that the temperature in the housing | casing 11 rises.

  Since a plurality of rear surface through holes 125d are formed in the rear surface plate 121d of the power supply device 161 so as to be aligned in the left and right and up and down directions, a large area for allowing air to pass through the rear surface plate 121d can be secured. Thereby, the air outside the housing 11 can be easily taken into the power supply device 161 from the rear through-hole 125d formed in the lower portion of the rear plate 121d, and the temperature inside the power supply device 161 can be prevented from rising. . Further, when excessive heat is generated from the power supply board, the heated air can be easily discharged to the outside of the housing 11 from the rear through hole 125d formed in the upper part of the rear plate 121d. And it can control that the temperature in case 11 rises. Certainly, if a through hole is formed in the rear plate 121d so that the through hole 46 formed in the lower left portion of the back plate 11c of the housing 11 is not covered by the rear plate 121d of the power supply device 161, air is passed through the rear plate 121d. Since a large area for passing can be secured, it becomes easier to take air outside the housing 11 into the power supply device 161 from the rear through-hole 125d formed in the lower portion of the rear plate 121d, or the upper portion of the rear plate 121d. The heated air can be easily discharged to the outside of the housing 11 from the rear through-hole 125d formed in the above. However, when a through hole is formed in the rear plate 121d so that the through hole 46 of the housing 11 is not covered by the rear plate 121d of the power supply device 161, a hand or a tool is inserted into the power supply device 161 from the through hole to supply power. There is a concern that fraud, such as illegally blocking, is performed. Therefore, in the present embodiment, a plurality of rear surface through holes 125d are formed in the rear surface plate 121d of the power supply device 161 so as to be aligned in the left-right and vertical directions. Thereby, in the rear surface plate 121d, it is possible to subdivide the region for allowing air to pass through and to reduce each of the rear surface through holes 125d. Therefore, it is possible to prevent a hand or a tool from being inserted from the rear surface through-hole 125d while ensuring a large area for allowing air to pass through the rear surface plate 121d. Therefore, it is possible to suppress fraud in the power supply device 161 and the like while suppressing the temperature inside the power supply device 161 from rising.

  A notch 44 is formed in one corner of the bottom plate 11b, and the back plate 11c and the left side plate 11d are fixed to the bottom plate 11b so as to stand on the peripheral edge of the top surface of the bottom plate 11b. In addition to penetrating, an opening 45 opened to the rear and left of the housing 11 can be formed at the left rear end of the housing 11. In such a configuration, the vertical dimension of the portion of the opening 45 opened to the rear and left of the casing 11 is the same as the thickness dimension of the bottom plate 11b. Therefore, the vertical dimension of the part can be increased by increasing the thickness dimension of the bottom plate 11b. Therefore, if the thickness of the bottom plate 11b is increased, it is possible to suppress the difficulty of taking in air outside the housing 11 from the rear and left sides of the opening 45 even if the lower portion of the opening 45 is blocked. it can. Further, with this configuration, the opening 45 can be formed in the housing 11 with a relatively simple configuration. For example, when the back plate 11c and the left side plate 11d are fixed so as to be in contact with the back and side surfaces of the bottom plate 11b, the openings are opened not only through the bottom plate 11b in the vertical direction but also at the rear and left sides of the housing 11. In order to form 45 at the left rear end portion of the housing 11, not only the bottom plate 11b but also the back plate 11c and the left plate 11d need to be formed, and the number of plates forming the notch increases. is there.

  Since the bottom plate 11b is made of a wooden material, the vertical dimension of the opening 45 can be made relatively large. When the bottom plate 11b is formed of a wooden material, the bottom plate 11b is required to have a strength that can withstand the weight of the slot machine 10 and the like. In order to ensure the strength, the bottom plate 11b has a predetermined thickness having the above strength. It is necessary to have it. For example, when the bottom plate 11b is formed of a metal material, even if the bottom plate 11b is thinner than when the bottom plate 11b is formed of a wooden material, a strength that can withstand the weight of the slot machine 10 can be obtained. For this reason, in order to form the bottom plate 11b from a metal material and to form the opening 45 having the same vertical dimension as that of the above-described embodiment in the casing 11, a notch is also formed in the back plate 11c and the left side plate 11d. Need to do. On the other hand, when the bottom plate 11b is formed of a wooden material, it is only necessary to form the notch 44 in the bottom plate 11b, and it is not necessary to form the notch in the back plate 11c and the left side plate 11d. Therefore, the opening 45 can be formed in the housing 11 with a relatively simple configuration by forming the bottom plate 11b from a wooden material.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the opening 45 is provided in the housing 11 by forming the notch portion 44 in the bottom plate 11b. However, the notch portion is formed in the bottom plate, the back plate, and the left side plate, respectively. An opening may be provided. For example, as shown in FIG. 12, an opening 203 is provided in the housing 201.

  In FIG. 12, a rectangular notch 202a is formed at one corner of the bottom plate 201a. In addition, a rectangular cutout 202b is formed at one corner of the back plate 201b, and a rectangular cutout 202c is formed at one of the corners of the left plate 201c. When the back plate 201b and the left side plate 201c are fixed to the bottom plate 201a so as to contact the peripheral edge of the upper surface of the bottom plate 201a, an opening 203 is formed at the left rear end of the housing 201 by the notches 202b to 202d. It is supposed to be formed.

  The power supply device 210 is configured by housing a power supply board in a metallic power supply box 211. The power supply box 211 is formed in a rectangular parallelepiped shape, and a plurality of horizontally long through holes 212a are formed in the lower surface plate 211a so as to be aligned in the front-rear and left-right directions. Further, a plurality of vertically long through holes 212b are formed in the rear surface plate 211b so as to be aligned in the vertical and horizontal directions, and a horizontally long through hole 212c is aligned in the longitudinal and vertical directions on the left surface plate 211c. A plurality are formed. Although illustration is omitted, a plurality of horizontally long through holes are formed in the upper surface plate of the power supply device 210 so as to be aligned in the front-rear and left-right directions.

  The power supply device 210 is installed in contact with the bottom plate 201a, the back plate 201b, and the left side plate 201c so that the left side plate 211c of the power supply box 211 faces the left side plate 201c side of the housing 11. Here, the notch 202 a of the bottom plate 201 a of the housing 201 is formed to be smaller than the lower surface plate 211 a of the power supply box 211. Further, the notch 202b of the back plate 201b of the housing 201 is formed smaller than the rear plate 211b of the power supply box 211, and the notch 202c of the left plate 201c of the housing 201 is formed smaller than the left plate 211c of the power supply box 211. Has been. Therefore, when the power supply device 210 is installed in the housing 201, the opening 203 is blocked by the power supply device 210.

  Next, the air flow inside the housing 201 will be briefly described.

  In the power supply device 210, the heated air is discharged from the through hole of the upper surface plate of the power supply device 210 to the outside of the power supply device 210, while the air outside the housing 201 passes through the opening 203. It is taken in from the through-hole 212a of 211a, the through-hole 212b of the rear surface plate 211b, and the through-hole 212c of the left surface plate 211c. Since not only the through hole 212a of the lower surface plate 211a but also the through hole 212b of the rear surface plate 211b and the through hole 212c of the left surface plate 211c can take in the air outside the housing 201, more air is supplied to the power supply device 210. Can be taken in. Therefore, it is possible to more suitably suppress the temperature in power supply device 210 from rising.

  Further, for example, when the case 201 is installed in an island facility of a game arcade, even if the lower part of the opening 203 of the case 201 is blocked by a pedestal of the island facility, the rear and left sides of the case 201 Air outside the casing 201 can be taken into the power supply device 210 through the through holes 212a to 212c of the power supply device 210 through the opening 203 opened to the outside. In addition, when the casing 201 is installed in an island facility of a game arcade, the lower portion of the opening 203 of the casing 201 is blocked by a pedestal of the island facility, and the opening 203 of the casing 201 is blocked by a medal lending device or the like. Even if the left side is blocked, air outside the casing 201 can be taken into the power supply apparatus 210 from the through holes 212a to 212c of the power supply apparatus 210 through the opening 203 opened to the rear of the casing 201. it can. As a result, even when the lower part or the left side of the opening 203 of the housing 201 is blocked, more air outside the housing 201 can be taken into the power supply device 210. Therefore, it is possible to more suitably suppress the temperature in power supply device 210 from rising.

  Note that when the vertical dimension of the notch 202b of the back plate 201b of the housing 201 and the notch 202c of the left side plate 201c increases, the vertical dimension of the opening 203 increases, so that the power supply device 210 is removed from the housing 201. The ratio of exposure increases. Therefore, when the vertical dimension of the opening 203 is increased, for example, when the case 201 is installed in an island facility of a game arcade, the case 201 is inclined so that the front side of the case 201 faces obliquely upward. If it is to be installed on the pedestal of the island facility, the left rear end of the power supply device 210 may hit the pedestal and be damaged. Therefore, the vertical dimension of the notch 202b of the back plate 201b of the housing 201 and the notch 202c of the left side plate 201c is the same even when the housing 201 is tilted so that the front surface of the housing 201 faces obliquely upward. It is preferable that the housing 201 hits the pedestal and the left rear end of the power supply device 210 does not hit the pedestal. Thereby, it can suppress that the power supply device 210 is damaged. Specifically, in the opening 203 of the housing 201, when the rear side edge of the bottom surface of the bottom plate 201a and the lower side edge of the back surface of the back plate 201b are connected with a straight line, the left side of the power supply device 210 is determined from the straight line. If the rear end portion does not protrude, the left rear end portion of the power supply device 161 does not hit the pedestal even when the housing 201 is tilted so that the front surface of the housing 201 faces obliquely upward. Therefore, by setting the vertical dimension of the notches 202b and 202c of the housing 201 so that the left rear end of the power supply device 210 does not protrude from the straight line, the power supply device 161 is prevented from being damaged. Can do. This also applies to the dimensions in the front-rear direction and the left-right direction of the opening 203 of the housing 201.

  (B) In the above-described embodiment, the opening 11 is formed in the casing 11 so as to penetrate the bottom plate 11b in the vertical direction and open to the rear and left of the casing 11. However, the casing 11 penetrates the bottom plate 11b in the vertical direction and the casing. An opening that opens to the rear of the body 11 may be formed in the housing 11, and an opening that penetrates the bottom plate 11 b in the vertical direction and opens to the left of the housing 11 may be formed in the housing 11. When an opening that penetrates the bottom plate 11b in the vertical direction and opens to the rear of the housing 11 is formed in the housing 11, the lower surface of the lower surface plate 121b is open because the rear of the opening is opened even if the lower portion of the opening is blocked. Air can be taken into the power supply device 161 from the through hole 125b. Therefore, it is possible to suppress the temperature inside the power supply device 161 from rising. When an opening that penetrates the bottom plate 11b in the vertical direction and opens to the left side of the housing 11 is formed in the housing 11, the lower surface plate 121b is open because the left side of the opening is opened even if the lower part of the opening is blocked. The air can be taken into the power supply device 161 from the lower surface through hole 125b. Therefore, it is possible to suppress the temperature inside the power supply device 161 from rising.

  (C) In the embodiment described above, the opening 45 is formed at the left rear end of the housing 11. However, if the region penetrating the bottom plate 11 b vertically is below the power supply device 161, the portion where the opening 45 is formed is the housing. It is not limited to the left rear end of the body 11. For example, when the power supply device 161 is installed so as to contact the bottom plate 11 b and the back plate 11 c of the housing 11, the power supply device 161 opens the opening 45 that penetrates the bottom plate 11 b vertically and opens to the rear of the housing 11. It is formed so as to be blocked. As a result, it is possible to achieve an effect of suppressing fraud performed inside the housing 11 while suppressing heat from being accumulated in the power supply device 161. Further, when the power supply device 161 is installed so as to contact the bottom plate 11b and the left side plate 11d of the housing 11, the power supply device 161 has an opening 45 that penetrates the bottom plate 11b vertically and opens to the left of the housing 11. It is formed so as to be closed by. As a result, it is possible to achieve an effect of suppressing fraud performed inside the housing 11 while suppressing heat from being accumulated in the power supply device 161. Therefore, an opening 45 corresponding to the installation position of the power supply device 161 is preferably formed in the housing 11.

  (D) In the above embodiment, the housing 11 is formed by standing and fixing the back plate 11c, the left side plate 11d, and the right side plate 11e on the peripheral edge of the upper surface of the bottom plate 11b, but the back plate 11c, the left side plate You may form the housing | casing 11 by making 11d and the right side board 11e contact | abut to the side part of the baseplate 11b, and fixing. However, in such a configuration, in order to form the same opening 45 as in the above embodiment, it is necessary to provide not only the notch portion 44 in the bottom plate 11b but also the notch portions in the back plate 11c and the left side plate 11d.

  (E) In the above embodiment, the through-hole 48 is formed in the housing 11 in addition to the opening 45, such as by forming the through-hole 48 in the upper part of the back plate 11c of the housing 11. 48 and the like need not be formed in the housing 11. However, if the through hole 48 other than the opening 45 is not formed in the casing 11, it is difficult to discharge the heated air to the outside of the casing 11, so that air is not generated inside the casing 11 or the power supply device 161. Convection is less likely to occur, and the temperature in the power supply device 161 may rise. For this reason, when the through hole 48 is formed in the casing 11 in addition to the opening 45, such as by forming a through hole 48 in the upper part of the back plate 11 c of the casing 11, the interior of the power supply device 161 or the interior of the casing 11 is better. Therefore, it is possible to easily generate air convection, and it is possible to suppress the temperature inside the power supply device 161 from rising.

  (F) In the above embodiment, the through hole 48 is formed in the upper part of the back plate 11 c of the housing 11. However, a through hole may be formed in the top plate 11 a of the housing 11. A through hole may be formed in the upper part of 11d or the right side plate 11e. However, when a through-hole is formed in the top plate 11a, it is considered that dust or the like easily enters the inside of the housing 11 from the through-hole. In this case, a dustproof cover or the like may be provided in the through hole. Thereby, it can suppress that dust etc. enter the case 11 inside. Further, when a through hole is formed in the upper part of the left side plate 11d or the right side plate 11e, if the medal lending device or the like is installed on the left or right side of the slot machine 10, the through hole may be blocked. The through hole may be formed at a position that is not blocked by the medal lending device.

  (G) In the above embodiment, the horizontally long through holes 125a, 125b, 125e and the vertically long through holes 125d are formed in the power supply box 121 of the power supply device 161. However, the heat generated from the power supply substrate is transferred to the outside of the power supply device 161. Any configuration can be used as long as it can be discharged, and its shape is arbitrary. For example, the through holes may be formed by forming the plates 121a, 121b, 121d, and 121e constituting the power supply box 121 in a lattice shape. It should be noted that a plurality of relatively small through-holes may be formed in order to exert a deterrent effect on the internal area of the power supply box 121.

  (H) In the above embodiment, the opening 45 of the housing 11 is closed by the lower surface plate 121b of the power supply device 161. However, the configuration is not limited to the lower surface plate 121b, and the opening 45 of the housing 11 is closed by the power supply device 161. It is also good. For example, the lower surface plate 121b of the power supply device 161 is provided with legs that extend downward from the peripheral edge portions corresponding to the front plate 121c and the side plate 121e. In such a configuration, the lower surface through hole 125b of the power supply device 161 and the opening 45 of the housing 11 are communicated with each other through a region surrounded by the housing (more specifically, the back plate 11c and the left side plate 11d) and the legs. Can do. Therefore, the air outside the housing 11 can be directly taken into the power supply device 161. Moreover, since the leg part of the power supply device 161 also serves as a shielding part for preventing the entry of a hand or a tool into the inside of the housing 11, there can be a deterrent effect against fraud performed inside the housing 11. it can.
