Description

  The present invention relates to a control board storage unit for a gaming machine and a gaming machine having such a control board storage unit for a gaming machine, and relates to a revolving type gaming machine called a slot machine (or pachislot), a seven machine, a blade The present invention can be applied to a ball game machine such as an object or a right object.

  Revolving type game machines and ball game machines are provided with a game machine control board (hereinafter referred to as “control board”) for controlling the game. Among these types of control boards, there are some which are used by being stored in predetermined control board storage units for gaming machines (hereinafter referred to as “control board storage units”) for various purposes. For example, the control board may be housed and used in a control board housing unit including a case member and a cover member attached to the case member.

  In the case of a revolving game machine or a ball game machine, for example, an electronic component (such as a ROM) mounted on a control board is replaced with an unauthorized electronic component (such as a ROM), or the control board itself is replaced with an unauthorized control board. It is required to prevent illegal acts such as exchange. Further, even if this kind of fraud is performed, it is required that the “execution of fraud” can be detected early.

  For this reason, the case side fixing portion provided on the case member and the cover side fixing portion provided on the cover member are connected and fixed by a sealing means such as a male screw (screw) to seal the control board storage unit. A “security cap for preventing unauthorized removal of a male screw” is attached to a cover member (see Patent Document 1, hereinafter referred to as “conventional example”). That is, the cover side fixing portion is formed by a vertically long hole portion, and the bottom portion positioned on the back end side of the cover side fixing portion and the case side fixing portion are fixed using a male screw (sealing means). . The fixing operation using the male screw is performed by inserting a tool (driver or the like) from the opening of the hole.

Further, in this conventional example, after the “fixing operation with the male screw”, a security cap is attached to the opening of the hole. The security cap according to this conventional example is configured so that it cannot be removed from the cover member (control board housing unit) unless it is destroyed. In the control board storage unit according to this conventional example, it is difficult to execute the illegal act as much as the security cap is added. In addition, when an unauthorized opening operation is performed on the control board storage unit, the trace remains, so that “execution of fraud” can be detected early.
JP 2004-113526 A

  However, this conventional example has the following problems. In other words, the “fixing operation with a male screw” is a troublesome operation of operating a tool (driver or the like) from the outside of the hole while inserting the male screw into the back end of the hole. In addition, it is necessary to perform the work of attaching the security cap to the cover member as a separate work after the “fixing work with male screws”. For this reason, according to this conventional example, there is a problem that the labor for assembling the control board storage unit is increased during the manufacture of the gaming machine, the maintenance / inspection of the gaming machine, and the like.

  The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a control board storage unit that is effective in preventing fraud while reducing the labor of assembly work. Another object is to provide a gaming machine including such a control board storage unit.

The control board storage unit according to claim 1 comprises:
A case member comprising a case body;
A cover member that is mounted on the case member and constitutes a storage body that stores the control board for the gaming machine inside the case body;
Comprising
The cover side fixing portion provided in the cover member and the case side fixing portion provided in the case member are sealed by being fixed with a sealing pin, and for preventing the removal of the sealing pin A control board storage unit for a gaming machine to which a security cap is attached,
The cover side fixing portion and the case side fixing portion are each formed with pin insertion portions communicating with each other,
The cover-side fixing portion includes a cylindrical wall that surrounds the pin insertion portion of the cover-side fixing portion in a circular shape while projecting opposite to the direction of the case-side fixing portion.
The sealing pin is inserted from the protruding end side of the cylindrical wall in the order of the cylindrical wall, the pin insertion portion of the cover side fixing portion, and the pin insertion portion of the case side fixing portion. And the case side fixing part,
The security cap includes a cap body and an inner pressing portion provided in a state of being spaced from the peripheral wall portion of the cap body inside the cap body while being integrated with the cap body. The cylindrical wall is attached to the cylindrical wall in a state in which the cylindrical wall is press-fitted between the peripheral wall portion and the inner pressing portion while pressing the sealing pin in the direction of the case-side fixing portion. To do.

  In the invention of claim 1, the crime prevention cap sandwiches the cylindrical wall between the peripheral wall portion of the cap body and the inner pressing portion (that is, sandwiches the outer peripheral surface and the inner peripheral surface of the cylindrical wall). Therefore, it is difficult to remove the security cap from the cover member without leaving a trace. Therefore, in the control board storage unit according to the first aspect of the present invention, it is difficult to perform “an illegal act of illegally removing the security cap and illegally releasing the sealing”. Moreover, even if a fraudulent act is performed, a trace of the fraudulent action remains due to the destroyed security cap, so that “execution of the fraudulent act” can be detected early.

  Furthermore, in the control board storage unit according to the first aspect of the present invention, the work of mounting the security cap and the work of mounting the sealing pin can be performed simultaneously and without using a tool. For example, align the tip of the sealing pin (tip along the insertion direction) concentrically with the inlet (the inlet along the insertion) of the “case-side fixing part”. Or the tip of the sealing pin is brought into contact, or the tip of the sealing pin is inserted into the inlet side of the “insertion part of the case side fixing part”. This is because when the security cap is attached to the cylindrical wall in this state, the security cap pushes the sealing pin in the insertion direction (that is, the direction of the case side fixing portion).

  Thus, according to the invention of claim 1, while preventing fraud and early detection when fraud is performed, “sealing work using a sealing pin” and “security cap” Can be performed at the same time. Therefore, according to the first aspect of the present invention, it is possible to obtain a control board storage unit that is effective in preventing fraud while reducing the labor of assembling work.

  However, the invention of claim 1 does not exclude an aspect in which the “sealing operation using the sealing pin” and the “blocking cancellation operation using the security cap” are performed separately. That is, the sealing pin is inserted from the protruding end side of the cylindrical wall (from the opening side), into the cylindrical wall, the insertion portion of the cover side fixing portion, and the insertion portion of the case side fixing portion in this order. It is not excluded that the security cap is attached to the cylindrical wall after the cover side fixing portion and the case side fixing portion are connected and fixed to each other on the cover side fixing portion and the case side fixing portion. In this aspect, in the “sealing operation using the sealing pin”, the sealing pin may be pushed in with an operator's finger or the like, or may be pushed in using a tool (bar-shaped tool) or the like. However, in any case, it is sufficient to simply push the sealing pin (that is, no troublesome work such as rotating the sealing pin around its axis is required). It does not increase the trouble of “stopping work”.

  In the invention of each claim, for example, the case member can be directly attached to a predetermined gaming machine or indirectly attached via a stay (bracket). In the invention of each claim, the case member may be composed of only the case main body, or the case main body and other members attached to the case main body (for example, the attachment member of the invention of claim 3 can be exemplified. However, the number may be singular or plural.).

  In the invention of each claim, it is possible to select various configurations of the case main body (whether or not the case main body = the case member) and the cover member. For example, both the case main body and the cover member may have a substantially container shape. In this case, for example, a storage body that stores the control board can be configured by connecting the openings of the both. Further, one of the case body and the cover member may have a substantially container shape, and the other may have a lid shape that closes the opening. In the invention of each claim, it is desirable that the case body (whether or not the case body is a case member) and the cover member are made of a transparent material (for example, a transparent synthetic resin). If the main part of the control board storage unit is transparent, if an unauthorized improvement is made to the control board in the control board storage unit, an "incorrect improvement" is discovered from outside the control board storage unit. It is also possible to do.

  The case member (whether or not the case body = case member) and the cover member may not be separable when the control board storage unit is opened (sealing is released). , May be separable. Here, as a specific example in which separation is impossible (hereinafter referred to as “specific example 1”), for example, one end of the cover member is supported on one end of the case member via a hinge mechanism, and the case member A control board housing unit that opens and closes by rotating the cover member so that the other end portion of the cover member and the other end portion of the cover member are in contact with or separated from each other can be exemplified.

b. Structure of Electronic Control Device Next, an outline of the electronic control device constituting the gaming machine 1 (outline of the configuration of the entire control circuit of the gaming machine 1) will be described with reference to FIG. This electronic control device is configured with a main control unit (main control unit) 100 and a sub-control unit 200 as main parts.

  The main control unit 100 is a control unit (that is, a game control unit) that controls the basic progress of the game, and executes important processes in the gaming machine 1 such as an internal lottery (described later). Further, the main control unit 140 receives information output from various information transmission means (start lever 35, stop buttons 36a to 36c, 1BET button 32a, 3BET button 32a, position detection sensors 12a to 12c, etc.), and receives predetermined information. After performing the calculation, various commands are output to the sub-control unit 200 and the like.

  The main control unit 100 is configured using a main control board 100A. The main control board 100 constitutes a specific example of a control board (control board for gaming machine), a CPU 101 that executes various control programs, a RAM 102 that functions as a work memory, a control program and an internal The ROM 103 that stores data used for the lottery is included.

  The sub control unit 200 is connected to the main control unit 100 using a predetermined transmission path 120. However, data transmission through the transmission path 120 is possible only in one direction from the main control unit 100 to the sub control unit 200 (data transmission from the sub control unit 200 to the main control unit 100 is impossible. Has been).

  The sub control unit 200 is a control unit (sub control unit) mainly responsible for game effects under the control of the main control unit 100, and is configured using a sub control board 200A. The sub-control board 200A constitutes another specific example of the control board (control board for gaming machine), a CPU 201 that executes various control programs, a RAM 202 that functions as a work memory, a control program, etc. The ROM 203 is stored. The sub-control unit 200 is connected to the liquid crystal display device 6 via the display device drive circuit unit 6A and to the speakers 8 and 8R via the speaker drive circuit unit 8A. Further, lamps 21v, 21w, 21x, 21y, and the like are connected to the sub-control unit 200 via the illumination drive circuit unit 9A.

  A start lever unit 35A, stop buttons 36a to 36c, a settlement button 33, a 1BET button 32a, a 3BET button 32b, and a return button 38 are connected to the main control unit 100 via a relay board 300. Yes. The start lever unit 35A includes the above-described start lever 35 and an “operation detection circuit unit (not shown)” for detecting an operation performed on the start lever 35.

  When the “operation detection circuit unit (not shown)” detects that the start lever 35 has been operated, a signal indicating that the start lever 35 has been operated (hereinafter referred to as “operation signal”) is transmitted via the relay board 300. Since it is transmitted to the control unit 100, the main control unit 100 can recognize the operation state of the start lever 35. When the stop buttons 36a to 36c, the settlement button 33, the BET button 32, or the return button 38 are operated, an “operation signal” is transmitted to the main control unit 100 via the relay board 300. The control unit 100 can recognize the operation states of these buttons 36a to 36c, 33, 32, and 38 based on the “operation signal”.

  In addition, the main control unit 100 is connected to the storage number display 28a, the winning combination number display 28b, the payout number display 28c, and the various lamp devices 7, 21a to 21c, 22 through the relay board 300. 26 etc. are connected.

  The main control unit 100 is connected to the symbol display device 10 via the motor drive circuit unit 50. In addition, the symbol display device 10 includes display reels 11a to 11c, motors (stepping motors) 12a to 12c arranged for the individual display reels 11a to 11c, and sensors arranged for the individual display reels 11a to 11c. (Optical sensors) 13a to 13c. Further, the sensors (optical sensors) 13 a to 13 c are connected to the main control unit 100 via the reel position detection circuit unit 55.

  Each of the motors (stepping motors) 12a to 12c is a motor for executing rotation and stopping of the corresponding display reels 11a to 11c. The shafts of the motors (stepping motors) 12a to 12c are used as the rotation shafts of the corresponding display reels 11a to 11c. Further, the rotation operation and the stop operation of each motor (stepping motor) 12 a to 12 c are controlled using a control signal transmitted from the main control unit 100.

  The sensors (optical sensors) 13a to 13c are used for detecting passage of index portions (for specifying a reference position, not shown) provided on the corresponding display reels 11a to 11c. That is, the index portion provided at a specific position along the circumferential direction of each display reel 11a to 11c rotates integrally with each display reel 11a to 11c and during one rotation (while rotating 360 degrees), It passes through the detection range of the sensors (optical sensors) 13a to 13c only once. Each time the index portions provided on the rotating display reels 11a to 11c pass through the detection ranges of the sensors (optical sensors) 13a to 13c, the reel position detection circuit portion 55 is moved from the sensors (optical sensors) 13a to 13c. Is transmitted.

  As described above, when the reel position detection circuit unit 55 receives the passage signal, a detection signal is transmitted from the reel position detection circuit unit 55 to the main control unit 100. For this reason, the main control part 100 can grasp | ascertain the present phase (rotation angle) of each display reel 11a-11c using this detection signal. That is, the main control unit 100 manages the reception timing of the detection signal and the number of drive pulses supplied to the motors (stepping motors) 12a to 12c after the reception. Accordingly, the main control unit 100 can grasp the current phase (rotation angle) of each of the display reels 11a to 11c.

  In the gaming machine 1, so-called “retraction control” is executed by utilizing the fact that the main control unit 100 can accurately grasp the current phase (rotation angle) of each of the display reels 11a to 11c. This “pull-in control” refers to the corresponding display reels 11 a to 11 c (corresponding motors 12 a to 12 c) even if each stop button 36 a to 36 c is operated and an operation signal (stop signal) is input to the main control unit 100. In this case, the display reels 11a to 11c are rotated by an additional rotation angle and then the rotation is stopped if necessary. For example, after each stop button 36a to 36c is operated and an operation signal (stop signal) is input to the main control unit 100, a predetermined number of frames (for example, 4 frames) is limited to a plurality of symbols as necessary. This refers to control for completing the stop of the display reels 11a to 11c after the corresponding display reels 11a to 11c are additionally rotated. When such “pull-in control” is performed, the main control unit 100 can stop the display reels 11a to 11c so that a desired symbol can be stopped on an effective winning line (effective line).

  A hopper 65 is connected to the main control unit 100 via a hopper drive circuit unit 60. When the hopper 65 is driven, a predetermined number of game medals are paid out from the game medal payout opening 41 toward the tray part 2E. In addition, since the door sensor 10S is connected to the main controller 100, signals (ON signal, OFF signal) output from the door sensor 10S are input to the main controller 100, and the hall computer HPC and the sub-controller 200. Sent to. The sub-control unit 200 controls driving of the operation selection device 78 based on the signals (ON signal, OFF signal).

(2) Outline of Symbol Fluctuation Game Next, a symbol variation game executed by the gaming machine 1 will be described with reference to FIG. First, when a prescribed number of game medals are bet, winning lines N1 to N5 are activated according to the number of bets.

A plurality of symbols are cyclically displayed at the portion of the arc length corresponding to the frame), and the variation display of the symbols is started. When the start lever 35 is operated, so-called “internal lottery” is started in the main control unit 100. This “internal lottery” is performed in order to determine whether or not to allow a winning combination.

  When the “internal lottery” is completed, the rotation speeds of all the display reels 11a to 11c become constant. When the player operates the stop buttons 36a, 36b, and 36c in a desired order (for example, forward pressing), the display reels 11a to 11c correspond to the operation order of the stop buttons 36a, 36b, and 36c. Stop in order. Normally, the display reels 11a to 11c are stopped at a predetermined phase (angular position) based on the result of the internal lottery and the operation mode applied to the stop buttons 36a, 36b, and 36c. That is, when the display reels 11a to 11c are stopped, the above-described “pull-in control” is executed.

  Thus, when the rotation of all the display reels 11a to 11c is stopped, one symbol variation game is ended.

Further, as shown in FIG. 29 (a), the other end along the axial direction of the head main body 96d (the end located rearward at the time of insertion, hereinafter simply referred to as the “other end”) side. Are formed with a pair of notches 96f and 96f opposed to each other in the radial direction of the head body 96d. These notches 96f and 96f are formed in a state in which the head main body 96d is opened at the inner peripheral surface, the outer peripheral surface, and the other end (the other end surface).

  The arm portion 95g protrudes (hangs down) in a substantially cantilevered manner from the back end portion (ceiling portion) 961f of the notch portions 95f. Further, engaging portions (hereinafter referred to as “second engaging portions”) 98j are provided at the protruding end portions of these arm portions 96g. The second engaging portion 95j is in a state of protruding outward from the outer peripheral surface of the head main body 96d (outside in the radial direction of the head main body 96d). That is, from the part located on one end side of the outer peripheral surface of the head main body 96d and at both ends along the radial direction of the head main body 96d, the "second engagement" The portion 96j "protrudes. The second engagement portion 96j is configured using an “engagement claw” having a substantially triangular longitudinal section.

  As shown in FIG. 28, a pair of engaging portions (hereinafter referred to as “first engaging portions”) is also formed in an intermediate portion of the outer peripheral surface of the head main body 96d (an intermediate portion along the axial direction of the head main body 96d). .) 96h is provided. These first engaging portions 96h are portions located at both ends along the radial direction of the head main body 96d, and the above-mentioned “second engaging portion 96j” is the circumferential direction of the head main body 96d. Are formed at different positions by “1/4” rounds. In other words, the “first engaging portion 96h” and the “second engaging portion 96j” are disposed at the disposition position along the axial direction of the head body 96d and the disposition position along the circumferential direction of the head body 96d. Both are different.

  As shown in FIG. 28, the leg support part 96e is a part constituting the fixed ends of the leg parts 96b and 96c, and includes a support main body part 96k and a pair of connecting pieces 96m and 96m. Among these, the support main body 96k is formed in a columnar shape (or a disc shape) having an outer diameter smaller than the inner diameter of the head main body 96d, and the head main body 96d has an axial center position at the opening on one end side of the head main body 96d. It is arranged so as to coincide with the axial center position of 96d. The connecting piece 96m is formed of a thin piece and is interposed between the outer peripheral portion of the support main body portion 96k and the inner wall portion of the head main body 96d, and integrates the support main body portion 96k with the head main body 96d. is there. That is, the pair of connecting pieces 96m and 96m have a function of fixing both ends along the radial direction of the support main body portion 96k to the inner wall portion of the head main body 96d while facing the radial direction of the head main body 96d. .

  As shown in FIG. 28 (b), the pair of leg portions 96b and 96c is the back surface of the support main body portion 96k (the surface located on the other end side of the head main body 96d), and the shaft of the support main body portion 96k. It protrudes in a substantially cantilever shape from a position eccentric from the center position. That is, the positions where both the leg portions 96b and 96c protrude are positions separated by 180 degrees around the axis of the support main body portion 96k. Further, an engaging portion (hereinafter referred to as “third engaging portion”) 96x is formed at the protruding end portion of each leg portion 96b, 96c. These “third engagement portions 96x” are configured using “engagement claws” having a substantially triangular longitudinal section. Each of the “third engagement portions 96x” is provided in a state of protruding outward in the radial direction of the support main body portion 96k. That is, both the third engaging portions 96x and 96x are provided so as to protrude in directions away from each other. ,

  As shown in FIG. 28 (a), on the surface of the support main body 96k (the surface exposed to the outside at the opening on one end side of the head main body 96d), an indicator (for identifying the sealing pin 96) 95w) is provided which can be composed of characters, graphics, and the like. In other words, the sealing pin 96 can be attached to each of the six cylindrical walls 95b arranged on the upper and lower sides of the main control board storage unit 80, but the sealing pin 96 attached to the uppermost cylindrical wall 95b. "B" to the sealing pin 96 attached to the second cylindrical wall 95b from the top, and "C" to the sealing pin 96 attached to the third cylindrical wall 95b from the top. "D" on the sealing pin 96 mounted on the fourth cylindrical wall 95b from the top, "E" on the sealing pin 96 mounted on the fifth cylindrical wall 95b from the top, A letter “F” is attached to each of the sealing pins 96 attached to the cylindrical wall 95b.

  As shown in FIG. 29 (b), when the legs 96b and 96c are not deformed, the diameter of the circumscribed circle CR drawn with respect to both “third engaging portions 96x” is the above-described pin difference. It becomes larger than the diameter of a penetration hole (P1-P6, S1-S6). For this reason, both the leg parts 96b and 96c cannot be inserted in the pin insertion holes (P1 to P6, S1 to S6). On the other hand, when both the leg portions 96b and 96c are bent so that their protruding end portions approach the axis of the support main body portion 96k (see the arrow V in the figure), both the “third engagement portions 96x” The diameter of the circumscribed circle drawn is smaller than the diameter of the pin insertion holes (P1 to P6, S1 to S6) described above. For this reason, both leg parts 96b and 96c can be inserted in the pin insertion hole (P1-P6, S1-S6).

  In the present embodiment, by breaking the connecting pieces 96m, 96m with a tool (nipper) or the like, the “part consisting of the support main body portion 96k and the leg portions 96b, 96c” can be separated from the head main body 96d. That is, when the connecting pieces 96m, 96m are broken with a tool (nipper) or the like, the sealing pin 96 is separated into a “pin main body portion 96p composed of the support main body portion 96k and the leg portions 96b, 96c” and the head main body 96d. (See FIG. 36).

  The sealing pin 96 includes three types of a total of six engaging portions (a first engaging portion 96h, a second engaging portion 96j, and a third engaging portion 96x). The vertical cross-sectional shape is configured by using “engaging claws” having a substantially triangular shape. More specifically, any of the engaging portions 96h, 96j, and 96x functions as a “return portion” for preventing the sealing pin 96 from coming off, and the tip portion (leg portion) of the sealing pin 96 is used. An inclined surface (hereinafter referred to as “guide surface”) M1 that approaches the axial center position of the sealing pin 96 as it goes in the direction of the projecting ends of 96b and 96c, and an engagement that is substantially orthogonal to the axial center of the sealing pin 96 {See FIG. 28 (b)}.

  As shown in FIGS. 30 and 31, the security cap 98 is an integrally formed product made of synthetic resin, and includes a cap body 98a, an inner pressing portion 98b, and an auxiliary pressing portion 98c. The cap body 98a includes a peripheral wall portion 98d configured in a substantially cylindrical shape, and a ceiling portion 98e disposed on one end side of the peripheral wall portion 98d. That is, the cap main body 98a is configured by a substantially cylindrical body having a ceiling portion 98e. However, a through hole 98h having a circular opening is formed at the axial center position of the ceiling portion 98e.

  The inner pressing portion 98b is configured using a cylindrical body having an inner diameter and a shaft center length smaller than those of the peripheral wall portion 98d, and protrudes (hangs down) from the back surface portion (a surface located inside the cap body 98a) of the ceiling portion 98e. Yes. Further, since the inner pressing portion 98b is disposed concentrically inside the peripheral wall portion 98d (in a state in which the axial center positions are matched), the outer peripheral surface of the inner pressing portion 98b and the inner peripheral surface of the peripheral wall portion 98d The width of the gap portion 98f between them (the width along the radial direction of the peripheral wall portion 98d) is constant in the entire peripheral region of the inner pressing portion 98b. In this embodiment, the gap 98f is made equal to or slightly smaller (for example, 0.1 mm smaller) than the thickness of the cylindrical wall 95b (thickness along the radial direction). .

  The auxiliary pressing portion 98c has a smaller inner diameter than the inner pressing portion 98b, and is configured using a cylindrical body whose axial center length is substantially equal to the inner pressing portion 98b. Further, the auxiliary pressing portion 98c is a back surface portion of the ceiling portion 98e and protrudes from a portion located at the periphery of the through hole 98h, and the auxiliary pressing portion 98c is concentrically (axially positioned on the inner side of the peripheral wall portion 98d. (In a state where they are matched).

  In the ceiling portion 98e, six breaking holes 98k penetrating the ceiling portion 98e in the thickness direction are provided in a portion located between the inner peripheral surface of the peripheral wall portion 98d and the portion from which the inner pressing portion 98b protrudes. Is formed.

  The six breaking holes 98k are equally spaced along a substantially ring-shaped portion (a ring-shaped portion surrounded by a circle Y1 indicated by a one-dot chain line and a circle Y2 indicated by a one-dot chain line), and a substantially arc-shaped opening. It is formed in a state having a shape. In the ring-shaped part 98j, the arc length of a part 96m located between the breaking holes 9k (the part where the breaking hole 98k is not formed and hereinafter referred to as “breaking part”) is 96m. It is smaller than the arc length of the hole 98k (1/10 to 1/2). And the peripheral wall part 98d and the inner side press part 98b are easily isolate | separated by destroying (breaking) the fracture | rupture site | part 96m with a tool (nipper).

(4) Sealing Method of Main Control Board Storage Unit 80 Next, a specific example of the sealing method of the main control board storage unit 80 will be described. In other words, the main control board storage unit 80 is sealed in six pieces: (a) after the cover member 92 is attached to the case main body 82 in the “closed attachment state”, and then arranged on the top and bottom of the main control board storage unit 80. Of these, the sealing pin 96 and the crime prevention cap 98 are attached to the cylindrical wall 95b located at the uppermost part or the cylindrical wall 95b located at the lowermost part. Alternatively, (b) the cover member 92 is attached to the case main body 82 in the “closed attachment state”, and the attachment member 87 is attached to the attachment space portion 85f, and then lined up and down the main control board storage unit 80. This is done by attaching a sealing pin 96 and a security cap 98 to any one of the cylindrical walls 95b.

  In any of the six cylindrical walls 95b arranged above and below the main control board storage unit 80, the sealing pin 96 and the crime prevention cap 98 are attached as follows. First, as shown in FIG. 32, the sealing pin 96 is inserted into the target cylindrical wall 95b with the tip end portion (the protruding end portion of the leg portions 96b and 96c) of the sealing pin 96 as the head. And the front-end | tip part (the protrusion part of leg part 96b, 96c) of this sealing pin 96 makes the head part the pin insertion hole (any one of P1-P6) located inside the cylindrical wall 95b used as object. ) At the inlet (opening located on the opening side of the cylindrical wall 95b), that is, toward the “insertion guide 95v”. However, at this time, the mounting posture of the sealing pin 96 (the mounting posture around its axis) is set to the posture (marking that can be composed of characters, figures, etc.) 95w (the mounting of the sealing pin 96 around the shaft center). Relying on (posture) as follows: In other words, the pair of “first engaging portions 96h” is arranged up and down, and the pair of “second engaging portions 96j” is arranged right and left. Accordingly, the pair of connecting pieces 96m and 96m are determined so as to be disposed on the left and right.

  As described above, when the sealing pin 96 is inserted, the “guide surface M1 of the third engaging portion 96x” at the tip of the sealing pin 96 faces the insertion guide portion 95v while being aligned in the front-rear direction ( The axial center of the sealing pin 96 and the axial center of the pin insertion holes P1 to P6 are aligned on the same line. Further, about half of the head body 96d along the axial direction is inserted into the target cylindrical wall 95b. When the head main body 96d is inserted, the guide surface M1 of the second engaging portion 96j slides with the opening of the cylindrical wall 95b, and the second engaging portion 96j is moved from the opening of the sealing pin 96. It is pressed in the axial direction of the sealing pin 96. For this reason, the pair of left and right arm portions 96g are inserted into the target cylindrical wall 95b while bending so as to narrow the interval between the protruding end portions. Then, the insertion of the sealing pin 96 is stopped at 1 o'clock at a position (insertion position) where the pair of upper and lower first engaging portions 96h contact the opening of the cylindrical wall 95b. Hereinafter, such a mounting state of the sealing pin 96 is referred to as a “temporary insertion state”.

  Thus, after the sealing pin 96 is set to the “temporary insertion state”, as shown in FIGS. 33 to 35, the security cap 98 is seen from the front of the head body 96d (from the opening side of the cylindrical wall 95). At this time, the security cap 98 presses the head main body 96 d against the inner side of the cylindrical wall 95. That is, the inner side of the security cap 98 (the back surface portion of the ceiling portion 98e) is concentrically opposed to the head main body 96d while the head main body 96d (the portion protruding from the target cylindrical wall 95b) inside the security cap 98. ) And the security cap 98 is pressed toward the cover side sealing portion 95.

  The sealing pin 96 is pushed (rearward) by this pressing, and when the “pushing amount applied to the sealing pin 96” reaches a predetermined amount, the pair of third engaging portions 96x are brought into contact with the insertion guide portion 95v. Touch. When the pushing amount is further increased, as shown in FIGS. 33A and 33B, the pair of third engaging portions 96x of the sealing pin 96 are pressed against each other by the insertion guide portion 95v. Reduce the interval. In other words, the diameter of the circumscribed circle (the circumscribed circle SR described above) of the pair of third engaging portions 96x is gradually enlarged toward the “anti-insertion direction of the sealing pin 96”, whereas the insertion guide The inner diameter of the portion 95v is “squeezed gradually along the insertion direction of the sealing pin 96. Therefore, when the sealing pin 96 is pushed, both the leg portions 96b and 96c have their protruding end portions (third engaging portions 96x). Is bent so as to approach the position of the axial center of the sealing pin 96. For this reason, the pair of third engaging portions 96x has a diameter of the circumscribed circle SR corresponding to the target pin insertion hole ( Any one of P1 to P6 and any one of S1 to S6) is reduced to a size that can pass through.

  When the “pushing amount applied to the sealing pin 96” is further increased, the pair of third engaging portions 96x reach the rear of the case-side sealing portion 85. At that time, the pair of third engaging portions 96x is restricted by the pin insertion holes (any one of S1 to S6) (the pair of third engaging portions 96x reduces the diameter of the circumscribed circle). Therefore, the pair of third engaging portions 96x are elastically brought into a state before being deformed (the aforementioned “third engaging portion 96x is brought close to the position of the axial center of the sealing pin 96). It returns to the state before bending.

  And a pair of 3rd engaging part 96x makes the engaging surface M2 the part located in the peripheral surface of pin insertion hole S1-S6 in the rear surface part (namely, rear surface part of the case side sealing part 85). ). When the sealing pin 96 is inserted into the pin insertion hole S1, the third engaging portion 96x passes through the “through-hole 851e of the cylindrical portion 85e (see FIG. 18)” and the case-side sealing portion. 85 is engaged with the rear surface portion.

  As described above, when the third engaging portion 96x is engaged with the case-side sealing portion 85, the sealing pin 96 is rearwardly formed by the protruding end surface of the inner pressing portion 98b and the protruding end surface of the auxiliary pressing portion 98c (see FIG. At the same time as being pushed toward the case member 8) side), the target cylindrical wall 95b is press-fitted into the “gap portion 98f between the outer peripheral surface of the inner pressing portion 98b and the inner peripheral surface of the peripheral wall portion 98d”. Is done. Moreover, the other engaging portions 96h and 96j of the sealing pin 96 engage with the engaged surfaces K11, K11, K21, and K21 of the cylindrical wall 95.

  That is, as shown in FIGS. 34 and 35, when the sealing pin 96 is pushed in, the first engaging portion 96h located above enters the upper engaged groove K1 and the first engaging portion 96 located below. The engaging portion 96h enters the lower engaged groove K1. At the same time, the second engaging portion 96j located on the left side enters the left engaged groove K2, and the second engaging portion 96j located on the right side enters the right engaged groove K2. To do. The engagement surface M2 of each engagement portion 96h, 98j abuts on the engagement surfaces K11, K11, K21, K21 located at the front ends of the engagement grooves K1, K1, K2, K2.

  As described above, since the sealing pin 96 includes the engaging portions 96h, 96j, and 96x at three different positions in the axial direction, when the sealing pin 96 is mounted (at the time of pushing operation), It is necessary to give elastic deformation to these engaging portions 96h, 96j, and 96x. In addition, at each axial center position, engaging portions 96h, 96h, 96j, 96j, 96x, and 96x are provided at two locations facing each other along the radial direction of the head main body 96d. For this reason, the sealing pin 96 is accurately pressed in the axial direction, and at each axial position, there are two engaging portions (96h, 96h, 96j) facing each other along the radial direction of the head body 96d. And 96j, 96x, and 96x) are uniformly elastically deformed, and in the direction of the axial center of the sealing pin 96, “shake (the axial center of the sealing pin 96 that is collinear with the axial center of the cylindrical wall 95 It is necessary to push in the sealing pin 96 while preventing the occurrence of “swaying from the same straight line)”. In this embodiment, the sealing pin 96 is pushed in this way using the security cap 98. be able to.

  That is, when the security cap 98 is attached, the target cylindrical wall 95b is press-fitted into the “gap portion 98f between the outer peripheral surface of the inner pressing portion 98b and the inner peripheral surface of the peripheral wall portion 98d”. Since the mounting posture is uniquely determined, the axis of the security cap 98 and the axis of the cylindrical wall 95 can be reliably aligned on the same straight line. This is because with the security cap 98 in this state, the sealing pin 96 can be pushed in without causing “blurring” in the axial direction of the sealing pin 96.

  When the pressing operation of the sealing pin 96 is completed, even if the sealing pin 96 is pulled out in the “reverse pressing direction”, as shown in FIGS. 34 and 35, the engagement of the third engaging portions 96 x is performed. The mating surface M2 and the rear surface portion of the case-side sealing portion 85, and the engaging surfaces M2 of the engaging portions 96h and 98j and the engaged surfaces K11 and K21 of the engaged grooves K1 and K2 are sealed. Since the abutment (engagement) is made so as to stop the extraction of the pins 96, the main control board housing unit 80 can be sealed.

  In addition, the security cap 98 is attached to the cylindrical wall 95b while press-fitting the entire cylindrical wall 95b into the ring-shaped gap 98f. That is, the crime prevention cap 98 is attached to the cylindrical wall 95b while firmly sandwiching the cylindrical wall 95b by the peripheral wall portion 98d and the inner pressing portion 98b. It is difficult to remove from the wall 95b.

  In this embodiment, the aspect in which the sealing pin 96 is pushed in when the security cap 98 is attached has been described. However, in the invention of each claim, the sealing pin 96 is pushed in and the security cap 98 is attached separately. This does not exclude the embodiment performed in (1). For example, the crime prevention cap 98 may be attached to the target cylindrical wall 95b after the sealing pin 96 is pushed in using an operator's finger, tool, or the like.

  The main control board storage unit 80 is opened, for example, according to the following procedure. First, the destruction portion 96m of the security cap 98 attached to the cylindrical wall 95b is broken (broken) with a tool (nipper) or the like to separate the peripheral wall portion 98d and the inner pressing portion 98b. As a result, only the peripheral wall portion 98d of the security cap 98 remains in a state of being attached to the cylindrical wall 95b, but the peripheral wall portion 98d is already separated from the inner pressing portion 98b (already, the cylindrical wall 95b). It is easy to remove the peripheral wall portion 98d from the target cylindrical wall 95b.

  After removing the peripheral wall portion 98d from the target cylindrical wall 95b, the connecting pieces 96m and 96m are broken (broken) with a tool (nipper) or the like, as shown in FIG. The pin body portion 96p "consisting of 96k and legs 96b, 96c" can be separated from the head body 96d {indicated by a broken line in Fig. 36 (a)}. In this case, some or all of the connecting pieces 96m and 96m may remain in the support main body 96k, but the connecting pieces 96m and 96m are sized so as to pass through the escape holes 95x and 95x that are arranged opposite to the left and right. It is said that. For this reason, when the support body 96k is pressed rearward, the connecting pieces 96m, 96m can pass through the escape holes 95x, 95x and reach the rear of the cover member 92 (in the direction of the arrow Y5).

  When the cover member 92 is removed from the case member 81, the “pin main body portion 96p including the support main body portion 96k and the leg portions 96b and 96c” remains on the case member 81 side, and the head main body 96d remains in the peripheral wall portion 98d. It is. At this time, the component part of the sealing pin 96 remaining on the cover member 92 and the case member 81 and the component part of the security cap 98 remaining on the cover member 92 are both destroyed products (the sealing pin 96 and the crime prevention cap 98 are destroyed. Is). Therefore, a person who visually recognizes these (such as a pachinko hall clerk) can immediately recognize that the main control board storage unit 80 has already been opened.

(5) Usage Example of Main Control Board Storage Unit 80 Next, a usage example of the main control board storage unit 80 will be described. However, the usage mode of the main control board storage unit 80 is not limited to the usage examples illustrated below.

  When the gaming machine 1 of this embodiment is shipped from a manufacturer, a sealing pin 96 and a security cap 98 are attached to the uppermost cylindrical wall 95b, and a pin insertion hole corresponding to this cylindrical wall 95b. The sealing pin 96 is inserted into (P1 and S1), and the cover member 92 and the case main body 82 are sealed (sealing of the main control board housing unit 80) and the sealing is prevented from being released. In this state, the main control board storage unit 80 is fixed in the outer main body 3 </ b> A using the stay 70. As the stay 70, for example, as shown in FIG. 37, a gripping portion 73 that grips at a plurality of locations along the width direction of the main control board storage unit 80 by a plurality of gripping portions 73, 73 provided on the left and right. What is provided with 73 can be illustrated.
