Description

  The present invention relates to a gaming machine represented by a slot machine (pachislot) and a pachinko machine, and more particularly to a fixing pin used in the gaming machine.

  In recent game machines (for example, slot machines), a reel is rotated by inserting a medal and operating a start lever, an internal lottery is determined by internal lottery, and a reel is stopped by operating a stop button. When a combination of symbols predetermined according to internal determination is displayed on the symbol display window, a winning combination is established. Then, when a winning combination with medal payout is established, a prescribed number of medals are paid out.

  By the way, when parts used for such a game stand are fixed, each part may be fixed using a pin member. For example, in Patent Document 1, a split pin is used to attach a component to a shaft that supports a rotating member of a firing operation handle mechanism for firing a game ball.

Japanese Patent No. 3479501

  However, the above-described split pin configuration has a problem that it is vulnerable to vibration and impact during the game. In game machines such as slot machines and pachinko machines, vibrations inevitably occur. For example, in the case of a pachinko machine, the vibration is always generated by the player's operation such as the operation of the launch handle, and in the case of the slot machine, the operation of the stop button or start lever. Further, vibration is also generated by a hopper paying-out operation or the like. Furthermore, vibrations and impacts are also generated when a game table is hit by a disgusting player. In addition, although the game table is not being played, vibrations and shocks are also generated in the game table when the game table is transported.

  For this reason, in the pin member used for a game stand, the pin member of the structure strong against a vibration and an impact was desired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a game pin fixing pin that can securely fix components to each other without falling off even if vibration or impact occurs. .

  In order to achieve the above object, the present invention is configured as follows.

  As one aspect of the present invention, a first component (for example, a heat sink 42; the same applies hereinafter) used for a game machine (for example, a slot machine, a pachinko; the same applies hereinafter) is replaced with a second component (for example, a substrate body 43; the same applies hereinafter). ) To be fixed to the gaming table (for example, the fixed pin member 80; the same shall apply hereinafter), and to the rod-like portion (for example, the shaft portion 51; the same shall apply hereinafter) to the fitting hole (for example, the hollow hole 50a; And a first pin (e.g., a push pin 50; the same applies below) having a locking claw (e.g., a locking claw 53; the same applies hereinafter) extending outward from the side surface of the rod-shaped portion, and the first pin A second pin that can be inserted into the fitting hole (e.g., the lock pin 60; the same applies hereinafter), and the first pin elastically deforms the locking claw inwardly, Installed in each of the second parts When the inserted through-holes (for example, through-holes 71 and 72; the same applies hereinafter) are inserted, the locking claws restored by elastic restoring force are locked to the second component after insertion, and the first The first part is fixed to the second part by pressing the part in the direction of the second part, and the second pin is inserted into the fitting hole of the first pin. It is characterized by restricting elastic deformation to the inside of the pawl.

  In one aspect of the present invention, in the game pin fixing pin for fixing the first component and the second component, the second pin strengthens the locking of the first pin to the second component. Can be prevented from falling off the second part, and the first part and the second part can be securely fixed. Further, since the second pin can be inserted and removed, the first pin can be easily removed to separate the first component and the second component.

  In this case, the first pin includes an engaging portion (for example, an engaging convex portion 54; the same applies hereinafter) that engages with the second pin, and the second pin is an object to be engaged with the first pin. An engagement portion (for example, an engagement recess 63; the same applies hereinafter) is provided, and the engagement portion of the first pin and the engaged portion of the second pin are engaged to be inserted into the fitting hole. Preferably, the second pin is fixed to the first pin and restricts elastic deformation to the inside of the locking claw. Thereby, since the first pin and the second pin are fixed, the first component and the second component can be fixed more firmly.

  The first pin is preferably longer than the second pin. Thereby, since the second pin does not protrude to the outside, it is possible to prevent interference with the second pin and to prevent the second pin from falling off due to the interference.

  Further, the direction in which the first pin is inserted into the through hole (for example, the direction from the space on the electronic component mounting surface side of the board main body 43 toward the board main body 43), and the second pin are the first pin. The direction of insertion into the fitting hole (for example, the direction from the space on the electronic component mounting surface side of the substrate main body 43 toward the substrate main body 43) is preferably the same. Thereby, the work efficiency of the operation | work which attaches a 1st component to a 2nd component can be improved.

  The first pin is in contact with the first part with a spring member (for example, spring 70; the same applies hereinafter) interposed in the rod-like portion, and the first part is moved by the biasing force of the spring member. Preferably, the first part is fixed to the second part by pressing in the second part direction. Thereby, even if the thickness of the first component and the second component varies, the height can be made uniform and securely fixed.

  Further, a third component (for example, an IC chip 44, a silicon sheet 45; the same applies hereinafter) exists between the first component and the second component, and the locking claw extends from the leading end of the first pin in the insertion direction. The length up to is preferably longer than the height of the third component. Thereby, it becomes easy to position a 1st pin in the through-hole of 2nd components, and work efficiency can be improved.

  In addition, a fourth component (for example, fan 41; the same applies hereinafter) is attached to the first component, and a collar portion (for example, a collar) formed at one end opposite to the insertion end of the first pin in the insertion direction. The portion 52; the same shall apply hereinafter) has a flat portion (for example, a flat portion 52a; the same applies hereinafter) formed on a part of its side surface, and the first pin is inserted into the through hole of the first component. It is preferable that the flat portion comes into contact with the side surface of the fourth component to enter a non-rotation holding state that does not rotate in the insertion direction, and is inserted into the through hole of the second component in the non-rotation holding state. Thereby, since the 1st pin does not rotate when positioning the 1st pin in the penetration hole of the 2nd part, it can position easily.

  In addition, in a state where the second pin is inserted into the fitting hole of the first pin, it is preferable that the color of the portion exposed to the outside of the second pin is different from the color of the first pin. . As a result, the first pin and the second pin can be clearly distinguished visually, so that forgetting to insert the second pin can be prevented.

  The first pin is preferably formed of a synthetic resin. Accordingly, since the first pin is light and easily elastically deformed, the operation of inserting the first pin into the through holes of the first component and the second component can be facilitated.

  In addition, it is preferable that the first pin has a predetermined section at least bifurcated from the tip in the insertion direction, and has the locking claw on the bifurcated side surface. Such a configuration of the first pin facilitates elastic deformation to the inside of the locking claw and allows the first pin to be easily inserted through the through holes of the first component and the second component.

  According to the game stand fixing pin of the present invention, even if vibration or impact occurs during the game, the component can be reliably fixed without falling off.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

It is not necessary to insert a medal when winning the re-game in the previous game. In step S102, a process related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is determined. After the process of step S102 is completed, the process proceeds to step S103.

  In step S103, a valid winning line is determined. After the process of step S103 is completed, the process proceeds to step S104.

  In step S104, the random number generated by the random number generator 311 is acquired. After the process of step S104 ends, the process proceeds to step S105.

  In step S105, an internal lottery of a winning combination is performed using the random number acquired in step S104 and the lottery data in the winning combination lottery table stored in the ROM 312. As a result of the internal lottery, when any winning combination is won internally, the winning combination flag is internally turned ON. After the process of step S105 is completed, the process proceeds to step S106.

  In step S106, reel stop control data is selected based on the internal lottery result or the like. After the process of step S106 is completed, the process proceeds to step S107.

  In step S107, rotation of all reels 110 to 112 is started by reel rotation start processing. After the process of step S107 is completed, the process proceeds to step S108.

  In step S108, the stop buttons 137 to 139 can be received, and the rotation of the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 is stopped by the reel stop control process. At this time, the reels 110 to 112 are stopped based on the reel stop control data selected in step S106. After the process of step S108 is completed, the process proceeds to step S109.

  In step S109, the winning determination of the symbols stopped when the stop buttons 137 to 139 are pressed is performed. Here, it is determined that the winning combination has been won when the winning symbol combination corresponding to the winning combination won or the flag carryover winning combination is displayed (displayed) on the active line. For example, if “replay-replay-replay” is arranged on the active line, it is determined that the replay is won. After the process of step S109 ends, the process proceeds to step S110.

  In step S110, a medal payout process is performed. In this medal payout process, if a winning combination with a medal payout (dividend) is won, the number of medals corresponding to the winning combination is paid out. After the process of step S110 is completed, the process proceeds to step S111.

  In step S111, game state control processing is performed. In the game state control process, control for shifting the game state is performed. For example, in the case of BB winning, preparation is made so that the BB game can be started from the next time, and in those final games, the normal game can be started from the next time. prepare. After step S111 is completed, the process returns to step S102.

<Processing of sub-control unit>
Next, the sub-control unit main process will be described in detail with reference to FIG. FIG. 6 is a flowchart showing interrupt processing and main processing of the sub-control unit 400 of the slot machine 100.

  First, interrupt processing will be described with reference to FIG. The CPU 410 of the sub-control unit 400 performs the process of FIG.

  In step S201, it is determined whether a control command from the main control unit 300 has been received. If a control command has been received from the main control unit 300, the process proceeds to step S202. If a control command has not been received from the main control unit 300, the process ends.

  In step S202, the control commands received from the main control unit 300 are sequentially stored without overwriting a predetermined area (referred to as a command storage area) in the RAM 413, and the process is terminated.

  Next, the main process will be described with reference to FIG. The CPU 410 of the sub-control unit 400 repeatedly executes the process (steps S301 to S305) in FIG.

  In step S301, it is determined whether or not at least one control command is stored in the command storage area. If the control command is stored, the process proceeds to step S302. If the control command is not stored, the process returns to step S301.

  In step S302, a control command is acquired from the command storage area, and its content is determined. The acquired control command is deleted from the command storage area. After the process of step S302 ends, the process proceeds to step S303.

  In step S303, an effect control process is performed according to the determination result in step S302. After the process of step S303 ends, the process proceeds to step S304.

  In step S304, it is determined whether there is output of control data. Specifically, it is determined whether or not the effect control process according to the determination result of step S302 outputs control data to the device driver of the sub-control unit 400 or the door / liquid crystal screen control unit 490. When the control data is output, the process proceeds to step S304, and when the control data is not output, the process returns to step S301.

  In step S 305, control data is output to the device driver of the sub-control unit 400 or the door / liquid crystal screen control unit 490. As a result, an effect process is executed via the device (for example, speaker, lamp, etc.), the door device 163, or the liquid crystal display device 157 of the sub-control unit 400. In addition, after the process of step S305 is complete | finished, it returns to step S301.

<Sub-board storage case>
Next, the configuration of the sub board storage case 220 will be described with reference to FIGS. 7 is an external perspective view of the sub-board storage case 220, and FIG. 8 is an exploded perspective view of the sub-board storage case 220.

  The sub board storage case 220 includes a front cover 10, a back cover 20, and a sub control board 30. Since the front cover 10 and the back cover 20 of the sub-board storage case 220 are molded using a translucent resin in the present embodiment, the sub-control board 30 stored inside from the outside of the sub-board storage case 220. Is visible.

  The front cover 10 and the back cover 20 are combined to form a box that forms a space for storing the sub control board 30. Specifically, the hook portions 11 formed on the left and right ends of the upper side surface of the front cover 10 are engaged with the hinge portions 21 formed on the left and right ends of the upper outer edge on the front side of the back cover 20, The upper ends of the front cover 10 and the back cover 20 are fastened, and screw hole portions 12 formed at the left and right ends of the lower surface of the front cover 10 are formed at the left and right ends of the lower outer edge of the back cover 20, respectively. The front cover 10 and the back cover are integrated by superimposing the screw holes 22 into the screw holes 22 and screwing the screws 37 into the screw holes.

  The sub-control board 30 is provided with a plurality of connector parts 33 for connecting electronic components (not shown) and external connectors (not shown) on a circuit board constituting the sub-control part 400. By connecting the external connector and the connector part 33 of the sub-control board 30, communication between the sub-control board 30 and the external device is possible. In the present embodiment, the sub control board 30 is physically composed of two control boards, that is, a sub control board 31 and a sub control board 32. The sub control board 31 and the sub control board 32 are connected by a connector 38 and can communicate with each other.

  The sub-control board 30 is fixed to the front side of the back cover 20 with the surface on which electronic components and the like are mounted facing the front cover 10 side. That is, the rectangular sub-control boards 31 and 32 have positioning holes 35 and fixing holes 36 at the corners, and are positioned by the positioning projections 25 provided on the front side of the back cover 20 by the positioning holes 35. The screw 37 inserted through the fixing hole 36 is fixed to the front side of the back cover 20. In the present embodiment, as shown in FIG. 8, the positioning projections 25 of the back cover 20 are inserted into and engaged with the positioning holes 35 of the pair of corners on the diagonal line, and another pair of corners on the diagonal line. The fixing hole 36 of the part and the fixing hole 26 of the back cover 20 are superposed and screwed together with a screw 37.

<Sub-control board 31, board fixing mechanism>
Next, the configuration of the sub-control board 31, in particular, a board fixing mechanism that fixes the heat sink 42 integrated with the fan 41 to the board body 43 will be described with reference to FIGS. 9 to 12. 9 is an external perspective view of the sub control board 31, FIG. 10 is an exploded perspective view of the sub control board 31, and FIG. 11 is an external perspective view of the push pin 50 and the lock pin 60 used in the board fixing mechanism. 12 is a cross-sectional view taken along line AA in FIG.

  The board fixing mechanism of the sub control board 31 is generally constituted by a fan 41, a heat sink 42, a board body 43, an IC chip 44, a silicon sheet 45, a mounting stay 46, and a fixing pin member 80.

  The fan 41 and the heat sink 42 are members for cooling the IC chip 44 mounted on the board main body 43. In the present embodiment, the fan 41 and the heat sink 42 are coupled and integrated via an attachment stay 46. ing. That is, first, the screw hole 78 formed in the center of the upper and lower edges of the rectangular heat sink 42 and the screw hole 74 formed in the pedestal portion 46 b of the mounting stay 46 are superposed and screwed with the screw 77. Then, after attaching the two attachment stays 46 to the heat sink 42, a pair of corners on the diagonal line among the screw holes 73 formed in the column part 46 a of the attachment stay 46 and the four corners of the rectangular fan 41. The fan 41 and the heat sink 42 are integrated with each other by superimposing the screw holes 75 formed on the screw holes 75 and screwing them together with screws 76 to attach the fan 41 to the mounting stay 46.

  On the other hand, an IC chip 44 in which a CPU (for example, CPU 410), a memory (for example, ROM 412), a RAM (for example, RAM 413), and a VDP (a processor for overall video output) are integrated is disposed on the substrate body 43. The front surface of the IC chip 44 is covered with a silicon sheet 45. As a result, when the heat sink 42 integrated with the fan 41 (hereinafter abbreviated as the integrated heat sink 42) is attached to the substrate body 43, the IC chip 44 has the silicon sheet 45 as shown in FIG. Therefore, the heat sink 42 is brought into contact with the integrated heat sink 42. The heat sink 42 in contact with the silicon sheet 45 is fixed to the substrate body 43 by a fixing pin member 80.

  In the present embodiment, the fixed pin member 80 includes a push pin 50, a lock pin 60, and a spring 70, as shown in FIG.

  That is, in the board fixing mechanism of the present embodiment, as shown in FIGS. 10 and 12, the push pins 50 having the locking claws 53 are penetrated at four positions on the outer peripheral edge of the IC chip 44 of the board body 43. The holes 71 and the through holes 72 respectively formed at the four left and right ends of the upper and lower edges of the heat sink 42 are inserted into the hole 71 and locked to the substrate body 43, while the push pin 50 is outside the substantially cylindrical shaft portion. When the fitted spring 70 presses the heat sink 42, the heat sink 42 and the substrate body 43 are fixed with the IC chip 44 interposed therebetween.

  Specifically, the push pin 50 is molded of a synthetic resin, and as shown in FIG. 11B, a hollow hole 50a is formed along the axial direction, and a shaft portion inserted into the through holes 71 and 72 is formed. 51 (also referred to as a rod-shaped portion) and a flange portion 52 formed at one end of the shaft portion 51 on the opposite side to the distal end in the insertion direction. The push pin 50 is made of synthetic resin so that it can be inserted into the through holes 71 and 72 more easily than a rigid metal, for example, an aluminum push pin. It is. It is also suitable for push pins because of its merit that it can be easily formed into various shapes.

  As will be described later, the hollow hole 50a is a fitting hole formed in accordance with the shape of the lock pin 60 so that the inserted lock pin 60 is fitted.

  The shaft portion 51 is provided with a snap fit portion 51a that is bifurcated in the axial direction and elastically deformed inward (in the direction in which the bifurcation approaches) on the distal end side (one end side) in the insertion direction. The snap fit portion 51 is formed in a taper shape so that its diameter increases as the distance from the distal end in the insertion direction increases, and a locking claw 53 extends outward from the side surface at the end. That is, the push pin 50 is inserted into the through holes 71 and 72 in a state where the snap fit portion 51a is elastically deformed inward, and after the penetration, the original shape before elastic deformation is caused by the elastic restoring force of the snap fit portion 51a. Therefore, the locking claw 53 is locked to the through hole 71 of the substrate body 43. The snap fit portion 51a is preferably formed in a section from the distal end in the insertion direction to approximately the center, and may be formed in any section as long as it is within the section.

  Further, a flat portion 52a cut out in the axial direction is formed on one side surface of the flange portion 52 (E1> E2 in the flange portion 52 as shown in FIG. 12). As will be described later, in the temporarily assembled state in which the push pin 50 is inserted into the through hole 72 of the integrated heat sink 42, the flat portion 52 a abuts on the side surface 41 a of the fan 41 and the axial direction of the push pin 50. Since the rotation (rotation with respect to the insertion direction of the push pin 50) is prevented and the push pin 51 is fixedly supported, in this embodiment, it is easy to position the push pin 50 in the through hole 71 of the substrate body 43. ing.

  As shown in FIG. 11A, the lock pin 60 has a cylindrical shaft portion 61 that is inserted into the hollow hole 50a of the push pin 50 from the distal end direction, and the opposite side of the distal end of the shaft portion 61 in the insertion direction. And a disc-shaped flange 62 formed at one end. An engagement recess 63 that engages with an engagement protrusion 54 (see FIG. 12) formed on the inner surface of the shaft portion 51 of the push pin 50 is formed near the center of the shaft portion 62 slightly. When the lock pin 60 is inserted into the hollow hole 50a of the push pin 50, the push pin 50 and the lock pin 60 are fixed by the engagement of the engagement convex portion 54 and the engagement concave portion 63. As a result, the lock pin 60 restricts the elastic deformation of the push pin 50 to the inside of the snap fit portion 51a, so that the locking claw 53 is securely locked to the substrate body 43, and the push pin The situation that 50 falls out does not occur. That is, even if vibration, impact, or the like occurs in the game table, the push pin 50 does not fall off the board body 43.

  In the present embodiment, as shown in FIG. 12, the length of the lock pin 60 is shorter than the length of the push pin 50, so that the lock pin 60 is inserted into the hollow hole 50 a of the push pin 50. Since the lock pin 50 does not protrude to the outside and there is no interference from others, the lock pin 50 itself has a structure that is difficult to drop off.

  Further, since the board fixing mechanism of the present embodiment is configured so that the lock pin 60 can be inserted and removed, the push pin 50 can be easily removed by removing the lock pin 60, and the combined heat sink 42 and Separation of the substrate body 43 is easy.

  Furthermore, in this embodiment, since the push pin 50 and the lock pin 60 are configured in different colors, it is visually easy to see that the lock pin 60 is inserted into the hollow hole 50a of the push 50. This makes it possible to prevent the user from forgetting to insert the lock pin 60. As for the color of the lock pin 60, at least the exposed part visible from the outside when the lock pin 60 is inserted may be a different color from the push pin 50. For example, the collar part visible from the outside Only 62 may be configured in a color different from the push pin 50.

  The spring 70 is a coil spring and is used as the fixed pin member 80 in a state of being fitted to the outside of the shaft portion 51 of the push pin 50, that is, between the snap fit portion 51 a and the flange portion 52. The state in which the spring 70 is fitted into the push pin 50, the snap fit portion 51a of the push pin 50 is inserted into the through hole 72 of the heat sink 42, and the locking portion 53 is locked to the through hole 72 is temporarily assembled. That's it. In the present embodiment, as will be described later, the heat sink 42 in a temporarily assembled state is attached to the substrate body 43, and the heat sink 42 is fixed to the substrate body 43.

  As described above, since the board fixing mechanism of the present embodiment is a fixing mechanism in a delicate part of the control board that requires careful handling, components are fastened using pin members (push pins 50 and lock pins 60). In addition, the spring 70 is used to absorb the tolerance variation of each component such as the heat sink 42, the substrate main body 43, and the IC chip 44, and to fix the components uniformly.

  Next, an attaching procedure for attaching the integrated heat sink 42 to the substrate body 43 will be described with reference to FIGS. Here, FIGS. 13 and 14 are cross-sectional views showing a mounting procedure for attaching the integrated heat sink 42 to the board body 43, and FIG. 15 is an external view of the sub-control board 31 showing the state of FIG. FIG. 16 is an external perspective view of the sub control board 31 showing the state of FIG. 14B, and FIG. 9 is an external perspective view of the sub control board 31 showing the state of FIG. 14C. In the following, description will be made according to the definition of directions shown in FIGS. 13 and 14. That is, the direction in which the integrated heat sink 42 approaches the substrate body 43 is downward (corresponding to the backward direction in FIGS. 9, 15, and 16), and the direction in which the integrated heat sink 42 is away from the substrate body 43 is upward ( (This corresponds to the forward direction of FIGS. 9, 15 and 16).

  First, as shown in FIGS. 13A and 15, the heat sink 42 in the temporarily assembled state is brought close to the substrate body 43 on which the IC chip 44 covered with the silicon sheet 45 is disposed. In this state, the flat portion 52a of the push pin 50 is in contact with the side surface 41a of the fan 41, and the spring 70 is not compressed.

  Next, as shown in FIG. 13B, the tip of the snap fit portion 51 a is positioned according to the through hole 71 of the substrate body 43. In this embodiment, as shown in FIG. 12, the length D2 of the snap fit portion 51a is longer than the height D1 of the IC chip 44 (more precisely, the height of the IC chip 44 + the thickness of the silicon sheet 45). Therefore, in a state where there is a gap between the integrated heat sink 42 and the IC chip 44, the tip of the snap fit portion 51a can abut on the inner peripheral side surface of the through hole 71, and the snap fit portion 51a can be easily positioned. It can be carried out.

  Next, as shown in FIG. 13 (c), when the flange portion 52 of the push pin 50 is pressed downward, the snap fit portion 51a of the push pin 50 is elastically deformed inward and slid downward on the through hole 71. The integrated heat sink 42 moves closer to the substrate body 43 and comes into contact with the silicon sheet 45. In this state, most of the snap fit portions 51a protrude to the back side of the board body 43 (side where no electronic component is disposed), but the locking claws 53 do not protrude to the back side of the board body 43. Further, the spring 70 is compressed by pressing the push pin 50.

  Next, as shown in FIG. 14 (a), the hook 52 of the push pin 50 is further pressed downward so that the locking claw 53 of the snap fit portion 51a of the push pin 50 passes through the through hole 71, When protruding to the back side of the main body 43, the snap fit portion 51a returns to its original posture before elastic deformation by its own restoring force, and the locking portion 53 is locked in the through hole 71. In this state, the spring 70 is further compressed by pressing the push pin 50. That is, in the state of FIG. 14A, the locking portion 53 formed on the distal end side (one end side) of the push pin 50 latches the substrate body 43 and is opposite to the distal end in the insertion direction ( The compressed spring 70 presses the integrated heat sink 42 downward (in a direction in which the integrated heat sink 42 is brought close to the substrate body 43) by the biasing force of the spring from the other end side. 43 is fixed by a push pin 50 and a spring 70 with the IC chip 44 interposed therebetween.

  Next, as shown in FIGS. 14B and 16, the lock pin 60 is inserted into the hollow hole 50 a of the push pin 50 from above. 14 (e) and FIG. 9, when the entire lock pin 60 is inserted into the hollow hole 50a of the push pin 50, the engagement recess 63 is engaged with the engagement protrusion 54, and the lock pin 60 is locked. Since the pin 60 is fixed to the push pin 50, the snap fit portion 51a of the push pin 50 is restricted from being elastically deformed inward. As a result, the substrate fixing mechanism of the present embodiment does not cause the push pin 50 to fall off because the locking of the locking portion 53 to the through hole 71 is released even if vibration or impact occurs, and the heat sink 42 The substrate body 43 is securely fixed.

  In the present embodiment, the integrated heat sink 42 is pressed in the direction of the substrate body 43 with the spring 70 interposed therebetween. However, it is not always necessary to press the heat sink 42 in the direction of the substrate body 43. If the snap fit portion 51 a can be restricted from being elastically deformed inward, a slight gap may be formed between the integrated heat sink 42 and the substrate body 43. That is, if the push pin 50 does not come off, the integrated heat sink 42 and the substrate body 43 may be loosely fixed.

  As described above, according to the board fixing mechanism of the slot machine 100 of the present embodiment, even if vibration or impact occurs, the parts can be reliably fixed without falling off. That is, according to the board fixing mechanism of the present embodiment, the heat sink 42 of the sub control board 31 can be reliably fixed to the board body 43 by using the fixing pin member 80.

  Note that the IC chip 44 used in a gaming machine such as a slot machine or a pachinko is a part that can be replaced for the first time with administrative procedures. That is, when the fan 41 or the heat sink 42 for cooling the IC chip 44 is detached from the substrate body 43 and the IC chip 44 fails, the failed IC chip 44 cannot be easily replaced. Therefore, it is very important from the viewpoint of reducing labor, such as subsequent maintenance work and procedural work, to securely fix the fan 41 and the heat sink 42 to the substrate body 43 using the fixing pin member 80 and not to drop off. .

  In the present embodiment, the lock pin 60 having the flange portion 62 is used to fit into the hollow hole 50a of the push pin 50, but only the shaft portion 61 having no flange portion 62 is used. You may make it fit in the hollow hole 50a of the push pin 50 using the lock pin 60 which becomes. In this case, the hollow hole 50a also has a shape (cylindrical shape) matched to the lock pin 60 consisting only of the shaft portion 61, and the lock pin 60 is not only from the upper direction (the heat sink 43 side) but also from the lower direction. It can also be inserted from the substrate body 43 side.

  Further, the lock pin 60 of the present embodiment regulates the inner operation of the snap fit portion 51a of the push pin 50, but may be a lock pin that regulates the outer operation as well as the inner operation. . For example, the operation of the snap fit portion 51a of the push pin 50 may be restricted using a lock pin 90 as shown in FIG. The lock pin 90 shown in FIG. 17 covers a shaft portion 90a that can be inserted into the hollow hole 50a of the push pin 50 and the entire outer side of the snap fit portion 51a of the push pin 50, and can be fitted to the snap fit portion 51a. Part 90b. When the push pin 50 attached to the temporarily assembled heat sink 42 is locked to the substrate main body 43 (state shown in FIG. 14A), the lock pin 90 has the shaft portion 90a from below (the substrate main body 43 side). While being inserted into the hollow hole 50a of the push pin 50 and fitting the cover portion 90b to the snap fit portion 51a, elastic deformation inside and outside the snap fit portion 51a of the push pin 50 is regulated. ing.

  Note that various modifications can be made to the shapes of the push pin and the lock pin. 18 and 19 show modified examples of the push pin and the lock pin. Here, FIG. 18A is an external perspective view of the push pin 50A and the lock pin 60A of the first modified example, and FIG. 18B is a view of FIG. 18 in a state where the lock pin 60A is inserted into the push pin 50A. It is sectional drawing which follows the BB line of a). FIG. 19A is an external perspective view of the push pin 50B and the lock pin 60B according to the second modification. FIG. 19B shows a state in which the lock pin 60B is inserted into the push pin 50B. It is the arrow view seen from the C direction of a).

  First, the push pin 50A and the lock pin 60A of the first modification will be described.

  The push pin 50A and the lock pin 60A shown in FIG. 18 regulate the elastic deformation to the inside of the locking claw 53A provided on the push pin 50A by the lock pin 60A, as in the above embodiment. The shape of the locking claw 53A of the pin 50A and the configuration of the engagement between the push pin 50A and the lock pin 60A are different from the above embodiment.

  The push pin 50A has a hollow hole 50aA formed in the axial direction, and is opposite to the shaft portion (also referred to as a rod-shaped portion) 51A inserted into the through holes 71 and 72 and the distal end of the shaft portion 51A in the insertion direction. And a flange portion 52A formed at one end of the head.

  The hollow hole 50aA is a fitting hole formed in a columnar shape in accordance with the shape of the lock pin 60A so that the inserted lock pin 60A is fitted.

  A snap fit portion 51aA is formed in the vicinity of the distal end of the shaft portion 51A in the insertion direction. The snap-fit portion 51aA is formed at the intermediate position between the slit 55A that is formed in the axial direction at the opposing position on the side surface and the two slits 55A on the side surface, and expands outward from the side surface toward the upper side. A locking claw 53A. When the lock pin 60A is inserted into the hollow hole 50aA from the distal end of the shaft portion 51A in the insertion direction, the snap-fit portion 51aA is elastically deformed outward by the formation of the slit 55A and is divided into two forks. Can be inserted. Further, the locking claw 53A is formed together with the engaging hole 54A by cutting the side surface into a U shape and bending the side surface cut into the U shape outward. Therefore, when the push pin 50A is fixed to the substrate body 43, the locking claw 53A is inserted into the through holes 71 and 72 while being elastically deformed inward, and after the penetration, the elastic restoring force of the locking claw 53A. Thus, the original shape before elastic deformation is restored, and the locking claw 53A is locked in the through hole 71 of the substrate body 43.

  The lock pin 60A includes a cylindrical shaft portion 61A that can be inserted into the hollow hole 50aA of the push pin 50A, and an engaging convex portion 63A that engages with the engaging hole 54A of the push pin 50A on the side surface of the shaft portion 61A. Is protruding. Therefore, when the lock pin 60A is inserted into the hollow hole 50aA of the push pin 50A, the push pin 50A and the lock pin 60A are fixed by engaging with the engaging convex portion 63A and the engaging hole 54A. . As a result, the lock pin 60A restricts the elastic deformation of the push pin 50A toward the inside of the locking claw 53A, so that the locking claw 53A is securely locked to the substrate body 43, and the push pin A situation where 50A falls off does not occur. That is, even if vibration, impact, or the like occurs in the gaming table, the push pin 50A does not fall off the board body 43.

  From the above, even when the push pin 50A and the lock pin 60A of the first modification are used for the substrate fixing mechanism, the same effect as that of the above embodiment can be obtained.

  Next, the push pin 50B and the lock pin 60B of the modified example 2 will be described.

  The push pin 50B and the lock pin 60B shown in FIG. 19 regulate the elastic deformation to the inside of the locking claw 53B provided on the push pin 50B by the lock pin 60B, as in the above embodiment. Unlike the embodiment, the push pin 50B and the lock pin 60B are not circular but rectangular.

  The push pin 50B has a U-shape that is bisected in the axial direction, and is opposite to the shaft portion (also referred to as a rod-shaped portion) 51B inserted into the through holes 71 and 72 and the distal end of the shaft portion 51B in the insertion direction. And an eaves part 52B formed at one end thereof.

  The shaft portion 51B forms a snap-fit portion 51aB that can be elastically deformed inwardly (in the direction in which the fork approaches), and a locking claw 53B is formed to protrude outward from the outer surface. Accordingly, when the push pin 50B is fixed to the substrate body 43, the snap fit portion 51aB is inserted into the through holes 71 and 72 in a state of being elastically deformed inward, and after the penetration, the elastic restoring force of the snap fit portion 51aB is inserted. Thus, the original shape before elastic deformation is restored, and the locking claw 53B is locked in the through hole 71 of the substrate body 43.

  The shaft portion 51B is formed with a fitting space 55B between the U-shaped bifurcated portions. The fitting space 55B is locked via an insertion hole (not shown) of the flange portion 52B. The pin 60B is inserted, and the lock pin 60B and the push pin 50B are fitted.

  The lock pin 60B includes a rectangular shaft portion 61B that is inserted into the fitting space 55B of the push pin 50B, and a rectangular flange portion 62B that is formed at one end opposite to the insertion direction tip of the shaft portion 61B. It has. Further, on the side surface of the shaft portion 61B, an engaging protrusion 63B is formed along the axial direction. On the other hand, on the inner side surface of the shaft portion 51B, an engagement groove 54B is formed along the axial direction corresponding to the engagement protrusion 63B, so that the lock pin 60B is fitted into the fitting space 55B of the push pin 50B. When engaging, the engaging protrusion 63B and the engaging groove 54B are engaged, and in this engaged state, the engaging protrusion 63B slides on the engaging groove 54B, so that the flange 62B The push pin 50B and the lock pin 60B are fixed by being fitted into the insertion hole of the flange portion 52B. As a result, the lock pin 60B restricts the elastic deformation of the push pin 50B toward the inside of the snap fit portion 51aB, so that the locking claw 53B is securely locked to the board body 43, and the push pin A situation where 50B falls off does not occur. That is, even if vibration, impact, or the like occurs in the gaming table, the push pin 50B does not fall off the board body 43.

  From the above, even when the push pin 50B and the lock pin 60B of Modification 2 are used for the substrate fixing mechanism, the same effect as that of the above embodiment can be obtained.

  In the above-described embodiment and the above modification, one end of the push pin has a bifurcated shape. However, one end of the push pin does not necessarily have to be divided into two, for example, FIG. A push pin 50C as shown in FIG. The push pin 50C shown in FIG. 20A has substantially the same configuration as that obtained by excluding the slit 55A from the push pin 50A of the first modification. In this case, unlike the lock pin 60A of the first modification, the lock pin 60C does not have the engaging convex portion 63A formed on the side surface of the shaft portion 61C, but instead, the shaft portion 51C of the push pin 50C. An engagement recess 63C that engages with an engagement protrusion 54C (see FIG. 20B showing a DD cross section of FIG. 20A) formed on the inner surface of the push pin 50C is formed. It is fixed to the hollow hole 50aC. Further, the inner surface of the locking claw 53C of the push pin 50C is brought into contact with the shaft portion 61C when the lock pin 60C is inserted into the hollow hole 50aC of the push pin 50C. The locking claw 53C is restricted from being elastically deformed inward, and the locking claw 53C is securely locked to the substrate body 43. Thus, one end of the push pin does not necessarily have to be divided into two forks.
