Description

  The present invention relates to a gaming machine, and in particular, a back body that substantially closes the back surface of a housing frame that surrounds the gaming machine, and a machine frame that is swingably supported so as to be openable and closable with respect to the housing frame. The present invention relates to a gaming machine having

  In a gaming machine such as a pachinko machine, the ejected game medium (hereinafter referred to as a ball) flows down on the game board surface, and in the course of the flow, the ball moves on the game board surface with gauges (also called nails) and blades. It turns around while colliding with the car, and the flow direction changes. As a result, if a ball wins at various winning holes arranged on the surface of the game board, a predetermined prize ball is paid out. On the other hand, if a ball flows into the out port without winning any prize hole, no prize ball is paid out. . The player can enjoy the game by demonstrating his / her skill in the ball or using the contingency in the flow of the ball and expecting the winning of the ball and the payout of the prize ball.

  Conventionally, such a pachinko machine is surrounded by a casing frame, and a game board is arranged so as to be accommodated inside the casing frame. The game board is held by a machine frame that is swingably supported so as to be openable and closable with respect to the housing frame. Various ball paths, various mechanical parts, circuit boards, etc. are provided on the back side of the machine frame and game board. Is attached.

  In other words, the ball path, which is an important part that composes and produces the game, various mechanism parts such as a prize ball payout device and a winning ball processing device, a payout control board for controlling the operation of these various mechanical parts, a symbol display device, etc. A game control board, a symbol control board, and the like for controlling the effect operation are configured such that the front is covered with a game board and a machine frame, and the upper and lower sides and the left and right sides are covered with a housing frame.

  However, the back of the pachinko machine, that is, the back side is not covered, and the above-mentioned important parts are substantially exposed. Therefore, the back side of the pachinko machine is defenseless against unauthorized access, and there is a risk that unauthorized parts will be performed from here.

  In recent years, a pachinko machine that can prevent unauthorized access to important parts from the back side by covering the back side with a back body (hereinafter referred to as a back plate) has been proposed. According to this, since the back surface of the pachinko machine is substantially closed, for example, it is possible to prevent an illegal game or the like that is performed by inserting a piano wire on the back side from the gap between adjacent pachinko machines (for example, (See Patent Document 1).

  Further, a configuration is also disclosed in which a substrate and a substrate case are detachably attached to the inside (inner wall) of the housing frame after the back side is covered with a back plate (see, for example, Patent Document 2). It is said that the maintenance can be facilitated and the load on the front door can be reduced.

JP 2004-105572 A Japanese Patent Laid-Open No. 2002-200292

  By the way, inside a general gaming machine island where gaming machines are provided, a ball supply facility, a banknote transport facility, and the like are arranged, and the rear side of the gaming machine via a housing frame in order to perform these maintenances Need access to.

  However, when the back side of the gaming machine is covered with a back plate, there is a problem that it is difficult to access the back side of the gaming machine due to the presence of the back plate, and maintenance work inside the island becomes complicated.

  In addition, according to the configuration disclosed in Patent Document 2, the substrate case can be reached as soon as the front door of the pachinko machine is opened, and the substrate case can be easily detached from the housing frame. . For this reason, it is relatively easy for a fraudster to remove a board together with a board case from the housing frame, and to illegally modify the board or replace the board itself with a fraudulent board. There's a problem.

  Various types of boards such as an image control board and a power supply control board are accommodated in the pachinko machine. Among them, there is a game control board (also called the main board) that controls the entire game in pachinko machines, but if this main board is tampered with or altered, there will be a shortage of fraudsters. Profits are supplied, and there is a risk that the amusement store (pachinko hall) will suffer unexpected disadvantages.

  The present invention has been made in view of the above circumstances, and even when a back body is installed on the back side of the gaming machine, the back body can be greatly opened forward, It is an exemplary object to provide a gaming machine that can improve accessibility to the back side and can effectively prevent an illegal act on a board disposed inside the gaming machine.

  In order to solve the above problems, a gaming machine as an exemplary aspect of the present invention includes a first frame surrounding the gaming machine and a front surface at a side edge swing support position at one side edge of the first frame. A second frame body swingably supported so as to be opened and closed, and disposed behind the first frame body to substantially close the back surface of the gaming machine, and rearward from the side edge rocking support position; The position inside the gaming machine with respect to the side edge swing support position is set as the inner swing support position, and the back body swingably supported by the first frame body so as to be openable and closable on the front side, and detachable on the front side of the back body A board case to which the board case is attached, and a mounting portion for mounting the board case is formed on the back body, and a mounting portion for mounting the board case is formed on the mounting portion. Based on the operation from the front side of the back body, Removing the substrate case from the back body with the scan attachment of is possible, characterized in that it is impossible.

  In the game machine according to the present invention, the back body is swingably supported with respect to the first frame body (for example, the housing frame) so that the front body can be opened and closed, so that the gaming machine can be opened by opening the back body in the front direction. It is possible to easily access the rear side of the rear body. For this reason, the back body arranged on the backmost surface of the gaming machine realizes both suppression of unauthorized access from the back side of the gaming machine and improvement in maintainability of a ball supply facility, a bill transport facility, etc. Can do.

  Since the swing support position (inner swing support position) of the back body is disposed behind the swing support position (side edge swing support position) of the second frame (for example, the machine frame), The size of the body in the left-right direction (that is, the width direction of the gaming machine) can be increased. As a result, the area of the back body can be increased, and the degree of freedom in design and space efficiency are increased.

  When the side edge swing support position of the second frame is located in front of the second frame or in the first frame body in the front-rear direction, the inner swing support position of the back body is the side edge of the second frame. If it coincides with or is in front of the swinging support position, when the rear body is opened forward, the rotation trajectory swells outward and may interfere with the inner wall of the first frame.

  However, in the present invention, the inner rocking support position of the back body is disposed behind the side edge rocking support position of the second frame, in other words, the inner rocking support position of the back body is substantially the same. In particular, since it is arranged behind the first frame body, the rotation trajectory of the back body does not swell greatly outward. Therefore, even if the lateral dimension of the back body is increased to the full inner wall dimension of the first frame, there is almost no possibility of interfering with the inner wall of the first frame when opening and closing. As a result, the opening / closing operation can be performed smoothly even if the lateral dimension of the back body is increased to enlarge the area.

  Further, by disposing the inner swing support position of the back body on the inner side of the gaming machine than the side edge swing support position of the second frame, when the second frame and the back body are opened, It can be opened greatly, and the accessibility to the rear thereof can be further improved.

  When opening the back body, it is necessary to open the second frame in advance. When the second frame body is opened, if the inner rocking support position of the back body is arranged outside the side edge rocking support position of the second frame body, the opening angle of the back body is increased. I can't. However, according to the present invention, the inner rocking support position of the back body is arranged on the inner side of the side edge rocking support position of the second frame, so compared to the case where it is arranged on the outside, When the opening angle of the second frame is the same, the opening angle of the back body can be increased.

  As a result, the possibility of interference between the back side of the second frame and the front side of the back body at the time of opening can be reduced. Thereby, the opening angle of the back body can be increased to improve the accessibility to the rear, the rear side of the second frame (also referred to as the back side or the back side), the front side of the back body. It is possible to increase the degree of freedom of component placement and size.

  In particular, on the back side of the second frame and the front side of the back body, various mechanical components such as a prize ball payout device and a winning ball processing device, and a main board (game control board) for controlling the operation of these various mechanical components. ), A design control board, a power supply board, etc. are often provided. For this reason, it is possible to reduce the possibility of breakage of these mechanical components, the control board, and the like due to interference between the second frame body and the back body when opened.

  Furthermore, the movable range of the back body is more compact than the movable range of the second frame by disposing the rocking support position of the back body at a position inside the gaming machine from the rocking support position of the second frame. Can be. For this reason, it is possible to facilitate the rotating operation of the back body in a state where the second frame body is opened, and it is possible to reduce the burden of handling the back body during maintenance inside the island.

  Also, a mounting part for mounting the board case is formed on the back body, and a mounting part for mounting on the mounting part is formed on the board case, so that the board case can be mounted based on the operation from the front side of the back body It is said that. Accordingly, the board case can be attached to the front side of the back body in a simple procedure, and for example, it is possible to improve the assembling property when assembling the gaming machine in the factory or to improve the maintenance property of the gaming machine. .

  In addition, since it is impossible to remove the board case from the back body based on the operation from the front side of the back body, for example, the board case is removed from the front side of the gaming machine, that is, from the side where the player is in the normal use state. It cannot be removed from the back body. Therefore, removal of the substrate case by a fraudulent person in a pachinko hall or the like can be prevented, and fraud to the substrate in the substrate case can be prevented.

  In the substrate case, electronic substrates such as a main substrate, an image control substrate, and a power supply control substrate are arranged, and these substrates are generally sealed in the substrate case. Therefore, it is impossible or very difficult to remove only the substrate from the substrate case while leaving the substrate case on the back plate.

  Here, the game medium means, for example, a ball used for the game in a game machine such as a pachinko machine, and the game apparatus body corresponds to a game board or the like for the ball to flow down. In addition, the “front” is a surface facing the player when the gaming device is installed in a gaming machine such as a pachinko machine, and the front is the direction from the game board surface to the player, that is, from the back of the game board. It means the direction toward the surface. On the contrary, the “rear surface” is a surface on the back side of the gaming machine, and the rear side means a direction from the surface of the game board toward the back surface. The left and right direction means the left and right in the width direction when viewing the gaming machine from the player. Furthermore, “inside” indicates a direction toward the center of the first frame.

  In a state in which the substrate case is attached to the back body, the attachment portion and the attached portion may be in a position shielded by the substrate case when viewed from the front side of the back body.

  The positions of the attachment part and the attachment part are shielded by the board case when viewed from the front side in a state where the board case is attached to the back body, and are not visible to the player or the fraudster. Therefore, the unauthorized person cannot grasp the position of the mounting portion of the substrate case, and the present invention further effectively prevents the unauthorized removal of the substrate case.

  In addition to being visually shielded by the substrate case, if the contact from the front side to the attachment portion or the attachment portion is also shielded, the tampering prevention effect can be further improved. For example, if the board case is mounted so that the board case and the front surface of the back body are in close contact with each other, there is almost no gap between the board case and the front surface of the back body, and not only is it visually shielded but also attached. Foreign objects such as piano wires that try to gain unauthorized access to the parts are also shielded.

  Based on the operation from the rear surface side of the back body, the substrate case may be removed from the back body.

  Since the substrate case can be removed from the back surface based on the operation from the rear surface side of the back surface, the substrate case can be easily removed from the back surface during maintenance of the substrate and the back surface. Removal from the front side is impossible, preventing unauthorized actions from the front side, and removal from the rear side is possible to improve maintainability, preventing fraud and convenience Improvement is compatible. When removing the board case, the back body and the housing frame are unlocked by the hall staff (pachinko hall clerk), etc., and the back body is opened forward, and the removal operation is performed from the rear facing surface side. Is called.

  The attachment portion may be a locking hole, and the attached portion may be a hook portion that can be engaged with the locking hole.

  Since the board case is attached to the back body by the engagement between the hook portion and the locking hole, the attachment can be easily performed without requiring a separate driver or other tools. In addition, when removing the substrate case by releasing the hook portion from the locking hole, a separate tool is not required, so that the troublesome maintenance work can be eliminated.

  The inner swing support position may be disposed on the front side of the back body and in the vicinity of the side edge.

  Since the swing support position of the back body is arranged on the front side, even if the back body is opened forward at approximately 90 °, a part of the back body does not protrude from the swing support position to the outside of the gaming machine. Therefore, even when a pillar member for a gaming machine island or the like is installed just outside the first frame, the back body can be greatly opened without interfering with it.

  In addition, since the rocking support position of the back body is arranged in the vicinity of the side edge thereof, when the back body is opened forward, the entire back body is substantially rotated forward and a part thereof is rotationally moved backward. There is nothing to do. Therefore, even if there is a pillar member for installing the gaming machine island behind the back body, there is no interference due to the opening / closing operation of the back body.

  The gaming machine may have an angle restricting structure that makes it impossible or difficult for the angle formed by the first frame body and the back body in the open state to be larger than a predetermined angle.

  The angle regulating structure makes it impossible or difficult for the angle between the first frame body and the back body to be larger than a predetermined angle, thereby preventing the back body from being unintentionally opened unnecessarily forward. be able to. As a result, inadvertent interference between the back body and the second frame body positioned in front of the back body can be prevented. Interference (collision) between the front surface side of the back body and the rear surface side of the second frame body can be avoided, so that the back body, the second frame body, or a structural component attached to them (for example, a video display device, It is possible to prevent damage and contamination of the substrate case.

  Further, if the angle restricting structure further has a function of making it difficult for the angle formed between the first frame body and the back body in the opened state to be less than a predetermined angle, for example, the angle formed is set to the predetermined angle. It can be stopped and held, and it is possible to prevent the back body from moving in the closing direction carelessly. It is possible to effectively prevent the operator's hands during maintenance work from being inadvertently pinched.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, it is possible to prevent an illegal game or the like with respect to the gaming machine by providing the back body on the first frame. Furthermore, since the back body can be opened largely forward with respect to the first frame body, access from the front side of the gaming machine to the back of the back body can be facilitated, and the island where the gaming machine is installed It becomes possible to improve internal maintainability.

  Moreover, since the board case attached to the front side of the back body cannot be removed from the front side, it is possible to effectively prevent an illegal act of removing the board case illegally. Furthermore, if the substrate case can be removed from the rear side of the back body, it is possible to achieve both an effective anti-fraud effect and an improvement in maintainability.

  The housing frame 3 is a frame for enclosing the periphery of the pachinko machine 2 and is configured in a substantially rectangular shape in plan view. Wood is often used as the material, but other materials such as resin and aluminum are also used. The housing frame 3 surrounds the upper and lower surfaces and the left and right side surfaces of the pachinko machine 2, and a hinge for swinging and supporting the machine frame 4 and the decorative frame 8 on the left side as viewed from the front surface (that is, the player side). Part 11 is provided. Further, it is a rear side of the housing frame (that is, the back side of the pachinko machine 2 and the gaming machine island side), and the back plate 5 is swingably supported on the left side when viewed from the front (front side). A hinge portion 12 (see FIGS. 2 and 4) is formed.

  The machine frame 4 is a frame for holding the game board unit 6, and an attachment opening for attaching the game board unit 6 is formed in the vicinity of the center thereof. An attachment portion for detachably attaching the game board unit 6 is provided around the attachment opening, and the machine frame 4 is configured to surround the game board unit 6. The machine frame 4 is disposed on the front side of the casing frame 3 and is pivotally supported by the casing frame 3 at the hinge portion 11, and swings so as to be openable and closable with respect to the casing frame 3 as shown in FIG. It is supported. The machine frame 4 is formed of resin or metal, and a back mechanism board (not shown) is disposed on the back side thereof. On the back mechanism board, a winning ball processing device (not shown) for counting and discharging the winning balls, a prize ball paying device (not shown) for counting and paying out the prize balls, and the like are arranged. Yes.

  The back plate 5 is a plate-like member that substantially seals the back of the housing frame 3 and substantially closes the back of the pachinko machine 2. By installing the back plate 5, unauthorized access that can be performed from the back side of the pachinko machine 2 can be effectively prevented.

  The back plate 5 has a box shape with the front side open, and inside the front side is an image control board 15, a main board (game control board) 16 for controlling the entire pachinko machine 2, and a power board. 17 etc. are stored. The back plate 5 is swingably supported by the housing frame 3 by a hinge portion 12 at the left front end portion when viewed from the front. By rotating the back plate 5 around the hinge portion 12 as a swing axis, the back plate 5 can be rotated to the front side by guiding the opening 3a of the housing frame 3 as shown in FIG. It is possible.

  FIG. 4 is an enlarged plan view of the pachinko machine 2 in which the machine frame 4 and the housing frame 3 are swingably supported with respect to the housing frame 3. The machine frame 4 has a structure that can be opened and closed as shown in FIG. 2 with the axis G1 of the hinge portion 11 provided on the front side of the housing frame 3 as a swing support position (side edge swing support position). ing. As shown in FIG. 4, the axis G <b> 1 of the hinge portion 11 is the left end portion of the housing frame 3, is disposed slightly forward of the housing frame 3, and is located near one side edge of the machine frame 4. ing.

  On the other hand, the back plate 5 has a structure that can be opened and closed as shown in FIG. 3 with the axis G2 of the hinge portion 12 provided on the back side of the housing frame 3 as the swing support position (inner swing support position). It has become. As shown in FIG. 4, the axis G <b> 2 of the hinge portion 12 is formed at the end portion of the hinge support portion 12 a formed in a cross-sectional shape Γ, and the rear surface of the housing frame 3 is more than the position where the hinge portion 11 is disposed. Further, it is disposed at a position closer to the inside of the housing frame 3 (toward the right side in front view, closer to the center of the housing frame) by a distance L1. The arrangement position of the shaft G2 corresponds to the vicinity of the side edge of the back plate 5.

  In a general pachinko machine, the axis of the hinge part of the machine frame is located in the housing frame in front of the housing frame or in the front-rear direction. Therefore, when the axis G2 of the back plate 5 coincides with or is in front of the position of the axis G1 of the machine frame 4, the rotation trajectory of the back plate 5 is outward (that is, the case frame 3). In the direction of the right side when viewed from the front in the width direction), and may interfere with the inner wall of the housing frame 3.

  However, in the pachinko machine 2 shown in the first embodiment, since the position of the axis G2 of the back plate 5 is arranged behind the position of the axis G1 of the machine frame 4, in other words, the back plate 5 Since the moving support position is disposed substantially behind the housing frame 3, the rotation trajectory of the opposite side edge 5 a of the back plate 5 does not bulge outward greatly with the opening operation of the back plate 5. As a result, interference between the opposite side edge 5a and the other side edge inner wall 3b of the housing frame 3 can be easily prevented even if the left and right dimensions of the back plate 5 are increased (see FIG. 5). Therefore, the back plate 5 can be smoothly opened and closed while increasing the left-right dimension of the back plate 5 to increase the degree of freedom of the arrangement space.

  Further, by arranging the axis G2 of the back plate 5 at a position inside the pachinko machine 2 with respect to the axis G1 of the machine frame 4, the back plate 5 is greatly opened when the machine frame 4 and the back plate 5 are opened. It is possible to improve the accessibility to the rear.

  When opening the back plate 5, it is necessary to open the machine casing 4 in advance. When the machine casing 4 is opened, if the position of the axis G2 of the back plate 5 is arranged outside the position of the axis G1 of the machine frame 4, the opening angle of the back plate 5 cannot be made large. However, according to the pachinko machine 2 shown in the first embodiment, the position of the axis G2 of the back plate 5 is arranged on the inner side of the position of the axis G1 of the machine frame 4, so that the case is arranged on the outer side. In contrast, when the opening angle of the machine casing 4 is the same, the opening angle of the back plate 5 can be increased.

  FIG. 5 shows a state in which the machine frame 4 is fully opened to the front side with respect to the housing frame 3 and the back plate 5 is further rotated forward by approximately 90 degrees. Compared with the axis G1 of the machine frame 4, the axis G2 of the back plate 5 is arranged inside the housing frame 3 by a distance L1, and the opening angle of the back plate 5 is made larger than before by the difference in the arrangement position. Can be taken.

  As a result, it is possible to reduce the possibility of interference between the back side of the machine casing 4 and the front side of the back plate 5 when opened. In particular, a back mechanism board (not shown) or the like is disposed on the back side of the machine casing 4 and a main board 16 and a power board 17 are provided on the front side of the back plate 5. It is possible to prevent breakage, failure, etc. from coming into contact with each other, and it is possible to increase the degree of freedom of component arrangement and size.

  Further, the back plate 5 is swingably supported by the housing frame 3 by the hinge portion 12 at the left front end (front side of the back body and in the vicinity of the side edge) when the back plate 5 is viewed from the front. As shown in FIG. 4, a space of a distance L <b> 2 from the left end portion of the housing frame 3 is secured on the left side of the face plate 5.

  When the pachinko machine 2 is installed in the pachinko hall, there may be a column member for installing the gaming machine island where the pachinko machine 2 is installed at a position 18 between the adjacent pachinko machine 2 (FIG. 4). (See dashed line inside.) However, in the pachinko machine 2 shown in the first embodiment, since a space of a distance L2 is secured on the left side of the housing frame 3, the pachinko machine 2 can be installed without any problem even if there is a pillar member at the position 18. can do.

  In addition, there is a case where the pillar member exists at the position 18a (see the two-dot chain line in FIG. 4), but in the first embodiment, the hinge support portion 12a has a Γ-shaped cross section to avoid the position 18a. In addition, since the axis G2 of the hinge portion 12 of the back plate 5 is disposed on the front side of the back plate 5, a part of the back plate 5 remains even if the back plate is greatly opened to approximately 90 °. There is no interference with the hinge support 12a. That is, even if the column member is installed at the position 18 or the position 18a, the back plate 5 can be opened forward sufficiently large.

  Further, since the position of the axis G2 of the back plate 5 is arranged in the vicinity of the side edge thereof, when the back plate 5 is opened forward, the entire back plate 5 is substantially rotated forward and a part thereof is moved backward. And never rotate. Therefore, even if the pillar member for the gaming machine island is located at the positions 18 and 18a behind the back plate 5, interference due to the opening / closing operation of the back plate 5 does not occur.

  The game board unit 6 includes a game board 20, a rail decoration 21, and a symbol display device 22, and is configured as a unit. On the front surface of the game board 20, a game board surface 20 a that realizes a game by flowing down a ball 24 as a game medium is formed. A rail ornament 21 is attached to the game board surface 20a so as to surround the substantially circular shape, and an inner surface 21a of the rail ornament 21 is erected with respect to the game board surface 20a to define a game area 6b. ing.

  In the game area 6b of the game board 20, a large number of gauges (nails) 25, an impeller 26, a winning port 28, a starting winning port 29, a big winning port 30, an out port 31, a symbol display device 22, and the like are arranged. . Here, the gauge 25 refers to a nail that is implanted in the game area 6b in order to change the flow direction of the ball 24 or to guide the ball 24. In addition, a series of nails arranged continuously or collectively may be referred to as a gauge.

  The gauge 25 and the impeller 26 are for colliding with the sphere 24 that has flowed down and changing the flow direction of the sphere 24. The winning opening 28 is a winning opening for paying out a predetermined number of prize balls based on the winning of the ball 24. In the game area 6b, there may be a case where a specific winning opening different from the case where the payout prize ball number is the winning opening 28 is arranged. In addition, there is a case where an electric winning opening provided with electric opening / closing blades for narrowing or widening the winning opening is provided in order to make the winning of the ball 24 variable. The start winning port 29 is a kind of the winning port 28, but has a function of starting symbol rotation of the symbol display device 22 based on the winning of the ball 24.

  The big winning opening 30 is a winning opening that can be opened and closed by the door 30a. When the symbol display device 22 stops and displays in a predetermined mode, for example, “7, 7, 7” or the like, the open / close door 30a opens and a large number of balls 24 win. Along with this, a large amount of prize balls are paid out. The out port 31 is for winning the ball that has flowed down to the lowest end of the game area 6b without discharging into any of the winning holes 28, 29, 30 and discharging it to the outside of the pachinko machine 2. It is arrange | positioned at the substantially lowest end of 6b.

  The symbol display device 22 includes a center ornament 22a and a liquid crystal display device (video display device) 22b. The center ornament 22a is formed of a resin molded part on which a character or the like has been shaped, and is used for decoratively producing a game in the game area 6b. The liquid crystal display device 22b is provided in the center portion of the center ornament 22a, and has a structure in which the screen periphery of the liquid crystal display device 22b is decoratively surrounded by characters or the like provided on the center ornament 22a.

  The liquid crystal display device 22b is for displaying a display pattern 22c that displays a three-digit number in a variable manner and an effect image 22d that provides an effect display such as a story display by an animated character. The variation display of the display symbol 22 c is performed based on the operation of the sphere 24. That is, the display symbol 22c is variably displayed based on the winning of a ball at the starting winning opening 29 or the passage of a ball to a starting opening (not shown) or a starting gate formed in the game area 6b. When the three-digit number stops in a predetermined manner (for example, “7, 7, 7” corresponding to the winning), the opening / closing door 30a is opened, and a large number of balls 24 win the big winning opening 30. It is configured as follows.

  When the ball 24 is launched toward the upper part in the game area 6b by a ball launching device (not shown), the ball 24 collides with the gauge 25 and flows down in the game area 6b while changing its flow direction. . In the middle of the flow, a certain thing wins the prize opening 28 to trigger a prize ball payout, and a certain thing wins the starting prize opening 29 to trigger a symbol variable game by the symbol display device 22. Things are discharged from the out port 31 to the outside of the pachinko machine 2 without winning any of the winning ports 28 or the like. Thus, when the ball 24 flows down on the game board 20, various games are realized.

[Embodiment 2]
FIG. 6 is an external perspective view of the pachinko machine 52 according to the second embodiment of the present invention as seen from the front, and FIG. 7 is an external perspective view of the pachinko machine 52 as seen from the rear. In FIG. 6, for ease of explanation of the interior of the pachinko machine 52, illustration of components arranged in front of the housing frame 53, such as a decorative frame, a front glass, a machine frame, and a game board unit, is omitted. Only the body frame 53 and the back plate 55 are obliquely obliquely viewed from the front. In the second embodiment, as in the first embodiment, the machine frame is swingably supported at the side edge swing support position with respect to the casing frame 53, and the back plate 55 is supported by the casing frame. 53 is supported at the inner swing support position. Both the machine frame and the back plate 55 can be opened and closed with respect to the housing frame 53. However, since these configurations are substantially the same as those of the first embodiment, the description thereof is omitted.

  A liquid crystal display device 70 is attached to the front surface 56 of the back plate 55, and substrate cases 57 to 59 are attached below the liquid crystal display device 70. In addition, a substrate case 60 is attached to the front side of the substrate case 58 so as to be stacked on the front and back of the substrate case 58. In each of these board cases 57-60, there are a main board as a game control board, an image control board for displaying an image for game effect on the liquid crystal display device 70, and a payout control board for controlling prize ball payout. Each of the power control boards for controlling and managing the power is sealed. In the second embodiment, only the substrate case 57 will be described as an example. Of course, the technical idea of the invention described in the second embodiment can also be applied to the other substrate cases 58-60. .

  FIG. 8 is an exploded perspective view for explaining the attachment state of the substrate case 57 and the back plate 55, as seen from the front. FIG. 9 is an exploded perspective view similar to FIG. 8 and is viewed from the rear. 8 and 9, only the substrate case 57 and the back plate 55 are shown for ease of explanation.

  The back plate 55 is formed with a locking hole (attachment portion) 55a and four guide portions 55b. The locking hole 55a is a through-hole penetrating from the front surface 56 to the rear surface 56b of the back plate 55, and is a hole into which a hook portion (attached portion) 61 of the substrate case 57 described later is engaged. The locking hole 55a is disposed at a position covered by the mounting surface 57a of the board case 57 when the board case 57 is mounted on the front surface 56. In the mounted state, the locking hole 55a is shielded by the board case 57 and forward. The locking hole 55a is not visible. Further, in the mounting state of the substrate case 57, the mounting surface 57a and the front surface 56 of the back plate 55 are substantially in close contact with each other, so that foreign matter cannot reach the locking hole 55a from the gap between both surfaces.

  The guide portion 55b is a portion that stands in front of the front surface 56 and is bent in an L shape. In the second embodiment, a part of the back plate 55 is cut and raised to form the guide portion 55b. The standing portion and the bent portion function as a guide rail, and assist the attachment of the substrate case 57 to the front surface 56. The four guide portions 55 b are formed at positions corresponding to the squares of the substantially rectangular parallelepiped board case 57, and these are also arranged at positions that are shielded by the mounting surface 57 a when the board case 57 is attached to the front surface 56. Yes.

  A hook portion 61 and four guide pieces 62 are disposed on the mounting surface 57 a of the substrate case 57. FIG. 10 is a side sectional view of the substrate case 57 cut along the section indicated by AA in FIG. The hook portion 61 is formed of, for example, plastic, metal, or the like, and the base portion 61a is configured to have elasticity in the front-rear direction. In the second embodiment, the hook portion 61 is formed of a separate part and is attached to the substrate case 57. A hook-like part 61b is formed at the tip of the base part 61a, and the board case 57 is attached to the front face 56 by engaging the hook-like part 61b with the locking hole 55a. The distal end portion of the hook-shaped portion 61b is disposed so as to protrude from the attachment surface 57a.

  The guide pieces 62 are flat plate portions arranged at four locations respectively corresponding to the guide portions 55b. A recess 62 a is formed around the guide piece 62. The guide portion 55b enters the recess 62a, and the guide piece 62 is fitted into the guide rail portion formed by the guide portion 55b, whereby the removal of the substrate case 57 and the back plate 55 in the front-rear direction is restricted.

  Specifically, the board case 57 is brought into contact with the front face 56 so that the mounting surface 57a of the board case 57 faces the front face 56 of the back plate 55 and the guide piece 62 is positioned on the right side of the guide portion 55b. At this time, the hook portion 61 is also located on the right side of the locking hole 55a. The hook-shaped portion 61 b of the hook portion 61 abuts on the front surface 56 and receives a biasing force from the front surface 56. The biasing force is absorbed by the elasticity of the base 61a.

  When the substrate case 57 is slid to the left as it is, the four guide pieces 62 are fitted into the guide rail portions while being guided by the four guide portions 55b. When the hook portion 61 reaches the position of the locking hole 55a, the urging force from the front surface is released, and the hook-shaped portion 61b is fitted into the locking hole 55a by the elasticity of the base portion 61a.

  As shown in FIG. 10, the flange portion 61 b has a right side surface 61 c that is a vertical surface with little inclination (that is, a surface extending in the front-rear direction). Therefore, once the hook-like portion 61b is fitted into the locking hole 55a, the right side surface 61c and the wall surface of the locking hole 55a come into contact with each other, and the board case cannot be slid rightward. Further, it is impossible to slide the substrate case 57 to the left at the position where the hook-like portion 61b is fitted in the locking hole 55a due to the interference between the right wall surface 62b of the recess 62a and the guide portion 55b. . Of course, it is impossible to remove the substrate case 57 forward (frontward) due to the engagement between the guide portion 55 b and the guide piece 62. Therefore, once the hook portion 61 is engaged with the locking hole 55a, the board case 57 cannot be removed from the back plate 55 based on at least an operation from the front plate 56 side of the back plate 55. Yes.

  On the other hand, when the board case 57 is attached, the front end portion of the hook-like portion 61b is visible and touched to the rear surface 56b side of the back plate 55 from the locking hole 55a (it can be pushed by hand). Yes. Therefore, when the front end portion of the hook-shaped portion 61b is pushed in from the rear surface 56b side of the back plate 55, the engagement between the hook-shaped portion 61b and the locking hole 55a is easily released based on the elasticity of the base portion 61a. When this engagement is released, the substrate case 57 can be slid to the right, and the substrate case 57 can be easily detached from the back plate 55.

  As described above, according to the substrate case 57 and the back plate 55, it is possible to easily attach the substrate case 57 to the front surface 56 without using a tool by an operation from the front surface 56 side of the back plate 55. Yes. Further, since the attachment portion of the substrate case 57 is shielded from the front surface 56 side, it is impossible to remove the once-attached substrate case 57 by an operation from the front surface 56 side. Since the mounting surface 57a of the substrate case 57 and the front surface 56 of the back plate 55 are in close contact with each other, it is possible to prevent foreign matter from being inserted into the gap.

  On the other hand, it is possible to easily remove the substrate case 57 from the back plate 55 without using a tool by an operation from the rear surface 56b side of the back plate 55. Therefore, it is possible to effectively prevent unauthorized removal of the substrate case 57 due to unauthorized access from the front surface 56 side, and also to enable removal of the substrate case 57 by simple operation from the rear surface 56b side, thereby preventing unauthorized operation and improving maintainability. Realization of both.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary.

  For example, in the second embodiment, the attachment structure to the back plate 55 of the substrate case 57 is configured by the locking hole 55a, the guide portion 55b, the hook portion 61, and the guide piece 62. An attachment structure that is fastened by fastening means such as screws from the 56b side, or an attachment structure that is fixed by other known fixing means may be employed. In this case, it is desirable that the fastening means or the like is shielded from being visible from the front surface 56 side even if part of the fastening means.

  For example, when a screw is used as the fastening means, the screw head is located on the rear surface 56b side, and therefore the board case 57 cannot be easily removed even if the screw shaft portion is visible from the front surface 56 side. However, by making the screw shaft portion invisible, it is possible to prevent an unauthorized person from grasping the mounting structure and even the position thereof, and a further fraud prevention effect can be obtained.

[Modification]
It is further desirable that the pachinko machine 52 according to the second embodiment has an angle regulation structure 76 (see FIG. 11) for regulating the front opening angle of the back plate 55. The angle regulating structure 76 is a structure that prevents or makes it difficult for the opening angle when the back plate 5 is opened forward with respect to the housing frame 53 to be larger than a predetermined angle. By adopting this angle restricting structure 76 in the vicinity of the axis G2, which is a connecting portion between the back plate 55 and the housing frame 53, it is possible to prevent the back plate 55 from being unintentionally opened forward.

  A schematic configuration of the angle regulating structure 76 will be described with reference to FIG. FIG. 11 is a structural diagram for explaining an angle regulating structure 76 provided in the pachinko machine 52 according to a modification of the present invention. The angle restricting structure 76 is disposed, for example, in the vicinity of the lower shaft G2 of the upper and lower swing support shafts G2 of the back plate 55. The swing plate 77 is fixed to the back plate 55, and swings and rotates together with the back plate 55. The swing plate 77 is formed with a fitting hole 77a so that the shaft G2 is fitted.

  A regulating portion 71 is disposed on the swing plate 77. Although details of the restricting portion 71 are not shown, it has a structure that has a ball as a restricting means and a spring as an urging means, and urges the ball downward by the spring. The ball protrudes downward from the swing plate 77 and is biased downward while abutting against the fixed plate 78 by a spring force.

  The fixing plate 78 is fixed to the housing frame 53 side. The back plate 55 is arranged to swing and rotate while the swing plate 77 slides on the upper surface of the fixed plate 78. The fixing plate 78 is fixed so that the shaft G2 protrudes upward, and two engagement holes 72 and 72b are formed at positions away from the fixing plate 78 in the radial direction. These engagement holes 72 and 72b are substantially circular, and have a shape in which a part of the ball is fitted.

  The engagement hole 72 is formed at a position where the ball is fitted when the back plate 55 is rotated forward by a predetermined angle. The engagement hole 72b is further opened by the back plate 55 and has an opening angle of about 90 °. It is formed at a position where the ball fits. Therefore, the radius from the center of the axis G2 to the center of the engagement holes 72 and 72b and the radius from the center of the fitting hole 77a to the center of the ball are substantially the same.

  When the back plate 55 is opened forward and the opening angle reaches a predetermined angle, the ball sliding on the fixed plate 78 is fitted into the engagement hole 72. Since the ball is urged downward by the spring, a suitable force is required for the ball to get over the engagement hole 72. Therefore, the back plate 55 is stopped and held at the opening position of a predetermined angle, and further opening and movement in the closing direction are difficult.

  When performing maintenance such as removing the substrate case 57 according to the present invention from the back plate 55, the back plate 55 and the housing frame 53 are unlocked and the back plate 55 is opened forward to some extent. Maintenance is required. However, the pachinko machine 52 has the angle restricting structure 76, and the back plate 55 is stopped and held at a predetermined opening angle, so that the back plate 55 is prevented from being unintentionally moved back and forth. The liquid crystal display device 70 and the substrate cases 57 to 60 attached to the front surface 56 of the back plate 55 are prevented from accidentally colliding with the machine frame and being damaged, and the back plate 55 is closed carelessly. Thus, the operator's hand is prevented from being pinched.

  If a stronger force is applied to the back plate 55 that is stopped and held at a predetermined angle in the opening direction, the ball can get over the engagement hole 72 and further open the back plate 55. When the back plate 55 is opened at approximately 90 °, the ball is fitted into the engagement hole 72b at that position, and is stopped and held again.
