[0004] [Patent Document 1] JP 2017-006393 A Summary of the Invention [Problem to be solved by the invention]

[0005] In such conventional gaming machines, effects are often produced by the operating means, but there is a demand for further increasing the interest in the game when the effects are produced by the operating means.

[0006] The present invention has been made in consideration of the above circumstances, and has an object to provide a gaming machine that can prevent a decline in interest in gaming. [Means for solving the problem]

[0007] Means 1: a first operating means and a second operating means operable by a player; A determination means for making a determination; a bonus awarding means for awarding a bonus to a player based on a predetermined result being obtained in the judgment by the judging means; a first operation related display means capable of displaying a first operation related display that prompts an operation of the first operating means; a first post-acceptance change execution means for executing a post-acceptance change in response to an operation acceptance performed on the first operating means; a second operation related display means capable of displaying a second operation related display that prompts the user to operate the second operating means; a second post-acceptance change execution means capable of executing a post-acceptance change in response to an operation acceptance on the second operating means; Equipped with at least a first predetermined mode and a first specific mode are prepared as modes for displaying the first operation-related display, and when the first operation means is operated and the operated state is maintained while the first operation-related display is being displayed in either the first predetermined mode or the first specific mode, the post-acceptance change in response to the operation acceptance for the first operation means can be executed a plurality of times; at least a second predetermined mode and a second specific mode are prepared as modes for displaying the second operation-related display, and when the second operation means is operated and the operation state is maintained while the second operation-related display is being displayed in either the second predetermined mode or the second specific mode, the post-acceptance change in response to the operation acceptance for the second operation means can be executed a plurality of times; When the first operation-related display is displayed in the first predetermined manner, even if the first predetermined manner is hidden, the first operation-related display may be newly displayed in the first specific manner before a predetermined time has elapsed since the first predetermined manner was hidden. when the second operation-related display is displayed in the second predetermined manner, there is no case in which the second operation-related display is newly displayed in the second specific manner before the predetermined time has elapsed since the second predetermined manner was made non-display, a first operation-related sound associated with an operation performed on the first operating means can be output when the first operation-related display is displayed at least in the first specific manner; a second operation-related sound associated with an operation performed on the second operating means can be output when the second operation-related display is displayed at least in the second specific manner; the first operation-related display can be displayed so as to show a periodic change; The second operation-related display can be displayed so as to show a periodic change. A gaming machine characterized by:

[0008] According to the above configuration, first, when the first operation means is operated and the operation state is maintained while the first operation-related display is displayed in either the first predetermined mode or the first specific mode, an "auto-repeated-hit function" that accepts multiple operations by simply maintaining the operation state can be enabled. Also, when the second operation means is operated and the operation state is maintained while the second operation-related display is displayed in either the second predetermined mode or the second specific mode, an "auto-repeated-hit function" that accepts multiple operations by simply maintaining the operation state can be enabled.

[0009] In this regard, in the above configuration, when the second operation-related display is displayed in the second predetermined manner, the second operation-related display is not newly displayed in the second specific manner before the predetermined time has elapsed since the second predetermined manner was hidden, and when the second operation means is maintained in an operating state while the second operation-related display is displayed in the second predetermined manner and an operation is accepted for the second operation means multiple times, the interval until a new change after the acceptance in response to the operation acceptance appears can be set to a time of a specific time or less. In other words, in this case, when the "auto-repeated-tap function" functions for the second operation means at an interval of a specific time or less, it is possible to suggest that the second predetermined manner will not be newly displayed in the second specific manner within a predetermined time since the second predetermined manner was hidden (see, for example, paragraphs 1681, 4310, etc.). Effect of the Invention

[0010] According to this invention, a decline in interest in games can be suppressed. [Brief description of the drawings]

[0028] [2-2. Bottom frame parts] The lower frame member 20 of the outer frame 2 is formed of a solid material (e.g., wood, plywood, etc.) of a predetermined thickness. The left-right length and top-bottom thickness of this lower frame member 20 are formed to be the same dimensions as those of the upper frame member 10, and the front-to-back width is formed to be longer than the front-to-back width of the upper frame member 10. The lower frame member 20 has engagement cutouts 21 that penetrate vertically and are recessed toward the left-to-right center at positions closer to the rear than the center in the front-to-back direction at both left and right ends. Lower lateral fixing parts 88 of a left lower connecting member 85C and a right lower connecting member 85D (described later) of the connecting member 85 are attached within the engagement cutouts 21.

[0029] The lower frame member 20 also has front end cutouts 22 recessed rearward from the front surface on both left and right ends. The width of the lower frame member 20 in the front-to-rear direction from the rear end of the front end cutouts 22 to the rear surface of the lower frame member 20 is formed to be the same dimension as the front-to-rear width of the upper frame member 10. When the lower frame member 20 is assembled to the outer frame 2, the area between the left and right front end cutouts 22 is inserted into the skirt board member 50.

[0030] [2-3. Left and right frame members] The left frame member 30 and the right frame member 40 of the outer frame 2 extend vertically with a constant cross-sectional shape, and are formed of extruded metal such as aluminum alloy. The left frame member 30 and the right frame member 40 are formed in shapes symmetrical to each other in a plan view. When assembled into the outer frame 2, the left frame member 30 and the right frame member 40 have, on the side surfaces that are on the outside in the left-right direction, recesses 31, 41 recessed inwardly between a position rearward of the center in the front-rear direction and near the rear end, and protrusions 32, 42 that bulge out from the side surfaces opposite the recesses 31, 41 and are formed with a hollow inside. The strength and rigidity of the left frame member 30 and the right frame member 40 are increased by the protrusions 32, 42. In addition, the rear lower horizontal fixing parts 88 of the upper left connecting member 85A and the upper right connecting member 85B of the connecting member 85, which will be described later, are inserted into the protrusions 32, 42 and attached.

[0031] Furthermore, a plurality of grooves extending vertically are formed on the surface of the left frame member 30 and the right frame member 40. These grooves provide fingerholds for an operator to easily hold the pachinko machine 1 when installing or transporting the pachinko machine 1 in an island facility of an amusement hall or the like, and also enhance the design quality of the exterior of the pachinko machine 1.

[0032] [2-4. Skirting board parts] The fascia board member 50 of the outer frame 2 is formed in a box shape with an open rear side. The fascia board member 50 includes a rear extension portion 51 extending rearward in a flat plate shape near the left end of the upper surface when viewed from the front, a left discharge hole 52 cut out in a U-shape from the left end of the rear extension portion 51 to a size that allows game balls to pass through and penetrating vertically, a right discharge hole 53 penetrating vertically to the right of the left discharge hole 52 in the rear extension portion 51 to a size that allows game balls to pass through, a standing wall portion 54 extending upward in a flat plate shape from the rear end of the upper surface of the fascia board member 50 including the rear end of the rear extension portion 51, and a return portion 55 bulging forward from the upper end of the standing wall portion 54 and inclining backward as the front surface moves upward.

[0033] A horizontal portion 71 of the outer frame lower hinge member 70 (described later) is attached to the front upper surface of the rear extension portion 51 and the upper surface of the rear extension portion 51 so that the outer frame lower hinge member 70 is placed on the front upper surface of the rear extension portion 51. The left discharge hole 52 of the outer frame member 50 is formed in a position that coincides with a discharge hole 74 (described later) of the outer frame lower hinge member 70 when assembled to the outer frame 2. The right discharge hole 53 is formed in a position that is to the right of the outer frame lower hinge member 70 when assembled to the outer frame 2. The right discharge hole 53 is formed larger than the left discharge hole 52.

[0034] Additionally, the top surface of the skirting board member 50 to the right of the rear extension 51 is inclined so that the front end side is lower. Additionally, the skirting board member 50 is provided with a left attachment portion 56 for attaching a left sliding member 81 to a portion of the top surface to the right of the rear extension 51, and a right attachment portion 57 for attaching a right sliding member 82 near the right end of the top surface. The bottom surface of the main frame 4 is placed on the top surface of the skirting board member 50 via the left sliding member 81 and the right sliding member 82.

[0035] As shown in the figure, the front surface of the skirting board member 50 is decorated with a shallow relief. Although not shown in the figure, the box-shaped interior of the skirting board member 50 is divided into a lattice shape by a plurality of ribs, which enhances the strength and rigidity of the skirting board member 50. The skirting board member 50 is formed so that the front half of the skirting board reinforcing member 80 can be housed therein.

[0036] [2-5. Upper hinge part on outer frame side] As shown in the figure, the outer frame side upper hinge member 60 of the outer frame 2 comprises a horizontally extending, flat upper fixing portion 61 with a rectangular outline, a flat forward extending portion 62 extending forward from the front end of the upper fixing portion 61, a bearing groove 63 extending forward from the right end of the forward extending portion 62 to the center of the left and right sides of the forward extending portion 62 and penetrating vertically, a flat lateral fixing portion 64 extending downward from the left edge of the upper fixing portion 61 in a planar view, and a flat hanging portion 65 extending downward from the edge from the left end of the forward extending portion 62, around the front end to the position where the bearing groove 63 opens, and which is continuous with the lateral fixing portion 64 (see Figure 16(b) etc.).

[0037] With the outer frame 2 assembled, the outer frame side upper hinge member 60 has its upper fixing portion 61 placed on the upper surface of the mounting step portion 12 of the upper frame member 10 and fixed with screws (not shown). The forward extension portion 62 extends forward beyond the front end of the upper frame member 10. The lateral fixing portion 64 is inserted from above into the recess 31 on the outer side surface of the left frame member 30 and fixed to the left frame member 30 with screws.

[0038] By inserting a main body frame upper hinge pin 622 of a main body frame upper hinge member 620 into a bearing groove 63, this outer frame side upper hinge member 60 can cooperate with the outer frame side lower hinge member 70 to support the main body frame 4 so that it can be opened and closed. This outer frame side upper hinge member 60 is formed by bending a metal plate by press molding.

[0039] [2-6. Locking parts] As shown in Fig. 16, the locking member 66 of the outer frame 2 includes a band-shaped locking body 66a extending forward and backward with a predetermined width on the left and right sides, an operating portion 66b protruding to the right from the rear end of the locking body 66a, an elastically deformable rod-shaped elastic portion 66c extending leftward from the rear end of the locking body 66a and then extending diagonally forward to the left, and a mounting hole 66d penetrating vertically near the rear end of the locking body 66a. The locking member 66 is made of synthetic resin. The locking member 66 is rotatably attached to the lower surface of the forward extension portion 62 of the outer frame side upper hinge member 60 by mounting screws 67.

[0040] The rear end of the locking body 66a of the locking member 66 is attached through the attachment hole 66d to a position rearward of the bearing groove 63 in the forward extending portion 62 of the outer frame side upper hinge member 60. Furthermore, when the locking member 66 is attached to the outer frame side upper hinge member 60, the locking body 66a can block the bearing groove 63 in a plan view, and the right side surface near the front end extends forward so as to be able to abut against a portion of the hanging portion 65 of the outer frame side upper hinge member 60 that extends to the opening of the bearing groove 63 (see FIG. 18).

[0041] In addition, the tip of elastic portion 66c extending leftward from the rear end of lock body 66a abuts against the inner circumferential surface of hanging portion 65 of outer-frame-side upper hinge member 60. Lock member 66 is biased in a direction in which its front end rotates leftward about mounting hole 66d by the biasing force of elastic portion 66c. Therefore, in a normal state, the right side surface near the front end of lock body 66a of lock member 66 abuts against hanging portion 65 (see FIG. 18). In this state, a space capable of accommodating main-body-frame-upper-hinge-pin 622 (described later) of main-body-frame-side upper hinge member 620 is formed in a portion of bearing groove 63 forward of lock body 66a.

[0042] By operating the operating portion 66b, the lock member 66 can rotate the lock body 66a against the biasing force of the elastic portion 66c. By operating the operating portion 66b, the lock body 66a can be rotated in a direction in which its front end moves leftward, so that the lock body 66a can be retracted from the bearing groove 63 in a plan view, and the bearing groove 63 can be fully opened. This allows the main body frame upper hinge pin 622 to be inserted into the bearing groove 63 or removed from the bearing groove 63.

[0043] [2-7. Lower hinge part on outer frame side] As shown in the figure, the outer frame side lower hinge member 70 of the outer frame 2 comprises a flat horizontal portion 71 extending horizontally, a flat rising portion 72 rising upward from a portion on the left side of the horizontal portion 71 rearward of the center in the front-to-rear direction, an outer frame lower hinge pin 73 protruding upward from near the front end of the horizontal portion 71, and a discharge hole 74 that penetrates the horizontal portion 71 from top to bottom and is large enough to allow only one game ball to pass through. This outer frame side lower hinge member 70 is formed by bending a metal plate by press molding.

[0044] The horizontal portion 71 of the outer frame side lower hinge member 70 is formed in a trapezoidal shape with the left side as the base in a plan view. The outer frame lower hinge pin 73 is cylindrical and is formed in a truncated cone shape with a narrowed upper end above the vertical center. This outer frame lower hinge pin 73 is attached to a position on the left side near the front end of the horizontal portion 71. The discharge hole 74 is formed in the horizontal portion 71 so as to contact the central part of the rising portion 72 in the front-rear direction and extend rightward from the left side of the horizontal portion 71 in an inverted U-shape. This discharge hole 74 is formed to be approximately the same size as the left discharge hole 52 of the fascia board member 50.

[0045] When the outer frame 2 is assembled, the outer frame-side lower hinge member 70 has a horizontal portion 71 placed on the upper surface near the left end of the front panel member 50 and on the rearward extending portion 51, and the horizontal portion 71 is fixed to the front panel reinforcing member 80 by a screw (not shown) that penetrates the upper surface of the front panel member 50. When the outer frame 2 is assembled, the rising portion 72 is attached by a screw (not shown) to a portion forward of the protruding portion 32 on the inner side surface of the left frame member 30. This outer frame-side lower hinge member 70 can cooperate with the outer frame-side upper hinge member 60 to attach the main frame 4 so as to be able to open and close by inserting the outer frame lower hinge pin 73 into a main frame lower hinge hole (not shown) in the main frame-side lower hinge member 640 of the main frame 4.

[0046] Furthermore, when the outer frame 2 is in an assembled state, the discharge hole 74 coincides with the left discharge hole 52 of the front panel member 50. This allows the game balls on the horizontal portion 71 to drop (discharge) to the rear side of the front panel member 50 through the discharge hole 74 and the left discharge hole 52. In more detail, when the main frame 4 is closed to the outer frame 2, the game balls that have fallen between the outer frame 2 and the main frame 4 roll to the rear side where the gap is wider, and can be discharged from the discharge hole 74, because the gap between the outer frame 2 and the main frame 4 gradually narrows as the main frame 4 is closed. In this case, the discharge hole 74 is formed at a position that is approximately the same as the rear end of the main body frame 4 when the main body frame 4 is closed against the outer frame 2 while assembled into the pachinko machine 1. Therefore, game balls that fall between the outer frame 2 and the main body frame 4 can be easily prevented from rolling rearward beyond the main body frame 4 by being discharged through the discharge hole 74, and game balls are less likely to become trapped in the area of ​​the lower hinge member 70 on the outer frame side.

[0047] [2-8. Connecting parts] The connecting members 85 of the outer frame 2 include an upper left connecting member 85A that connects the upper frame member 10 and the left frame member 30, an upper right connecting member 85B that connects the upper frame member 10 and the right frame member 40, a lower left connecting member 85C that connects the lower frame member 20 and the left frame member 30, and a lower right connecting member 85D that connects the lower frame member 20 and the right frame member 40.

[0048] The connecting member 85 includes a flat horizontal fixing portion 86 extending horizontally, a flat upper lateral fixing portion 87 extending upward from either the left or right side of the horizontal fixing portion 86, and a flat lower lateral fixing portion 88 extending downward from the same side of the horizontal fixing portion 86 as the portion from which the upper lateral fixing portion 87 extends. This connecting member 85 is formed by bending a flat metal plate.

[0049] In the upper left connecting member 85A and the upper right connecting member 85B, an upper horizontal fixing portion 87 extends upward from the center in the front-to-rear direction of the horizontal fixing portion 86, and a lower horizontal fixing portion 88 extends downward from both the front and rear sides of the upper horizontal fixing portion 87. In other words, the upper left connecting member 85A and the upper right connecting member 85B are provided with two lower horizontal fixing portions 88 spaced apart in the front-to-rear direction. The horizontal fixing portion 86 of the upper left connecting member 85A and the upper right connecting member 85B is fixed to the upper frame member 10 while abutting against the lower surface of the upper frame member 10. In addition, the upper horizontal fixing portion 87 of the upper left connecting member 85A and the upper right connecting member 85B is inserted into the engagement notch 21 of the upper frame member 10 and fixed to the left-to-right end of the upper frame member 10. Additionally, the front lower horizontal fixing portions 88 of the upper-left connecting member 85A and the upper-right connecting member 85B are fixed to the inner side surfaces forward of the protruding portions 32, 42 of the left frame member 30 and the right frame member 40, respectively. Furthermore, the rear lower horizontal fixing portions 88 of the upper-left connecting member 85A and the upper-right connecting member 85B are fixed to the left frame member 30 and the right frame member 40, respectively, by screws that are inserted into the protruding portions 32, 42 of the left frame member 30 and the right frame member 40 and screwed in from the outer side surfaces.

[0050] In the left lower connecting member 85C and the right lower connecting member 85D, the rear end of the upper horizontal fixing part 87 protrudes further rearward than the rear end of the horizontal fixing part 86, and the lower horizontal fixing part 88 extends downward from the lower end of the part of the upper horizontal fixing part 87 that protrudes further rearward than the horizontal fixing part 86. In addition, the left lower connecting member 85C and the right lower connecting member 85D further include a bent part 89 that protrudes from the rear end of the upper horizontal fixing part 87 to the same side as the horizontal fixing part 86. The horizontal fixing part 86 of the left lower connecting member 85C and the right lower connecting member 85D is fixed in a state of abutting against the upper surface of the lower frame member 20. In addition, the upper horizontal fixing part 87 of the left lower connecting member 85C and the right lower connecting member 85D is fixed to the inner side surface forward of the protruding parts 32, 42 of the left frame member 30 and the right frame member 40, respectively. Furthermore, the lower horizontal fixing portions 88 of the lower left connecting member 85C and the lower right connecting member 85D are inserted into the engagement notches 21 of the lower frame member 20 and fixed to the left and right end faces of the lower frame member 20, respectively.

[0051] [2-9. Locking mechanism for the upper hinge part on the outer frame] Next, the locking mechanism for the main body frame 4 upper hinge member 620 by the lock member 66 in the outer frame upper hinge member 60 of the outer frame 2 of the pachinko machine 1 of this embodiment will be described with reference to Figures 17 and 18. Figure 17(a) is an enlarged perspective view showing a state in which the main body frame upper hinge member of the main body frame is removed from the outer frame upper hinge member of the outer frame, and (b) is an enlarged perspective view showing a state in which the main body upper hinge member is attached to the outer upper hinge member. Figure 18 is an explanatory diagram showing the action of the lock member in the outer frame.

[0052] When the locking member 66 of the outer frame 2 is attached to the forward extension portion 62 of the outer frame side upper hinge member 60 (normal state), the tip of the elastic portion 66c abuts the inner surface of the hanging portion 65, and the locking body 66a blocks part of the bearing groove 63 which is bent in a L-shape. At the same time, the tip portion of the locking body 66a does not block the deepest part of the bearing groove 63, and a space is formed in the deepest part of the bearing groove 63 into which the main body frame upper hinge pin 622 of the main body frame side upper hinge member 620 of the main body frame 4 can be inserted.

[0053] In this embodiment, the support mechanism for main frame hinge pin 622 using outer frame upper hinge member 60 and lock member 66 is in a normal support state in which main frame hinge pin 622 is inserted into the deepest part of bearing groove 63 and the right side surface of the front end of lock body 66a is close to right-side hanging portion 65 (in this state, there is a small gap between the right side surface of the front end of lock body 66a and right-side hanging portion 65 and they are not in contact), with the respective centers of main frame hinge pin 622 located in the deepest part of bent bearing groove 63 and the front end face of lock body 66a shifted diagonally and facing each other.

[0054] In this normal support state, the hinge pin 622 on the main frame, which supports the heavy main frame 4, is in contact with the front end of the bearing groove 63, so that the hinge pin 622 on the main frame exerts almost no load on the front end surface of the lock body 66a. In other words, the elastic portion 66c of the lock member 66 is not subjected to any load. Since the front end surface of the lock body 66a is formed in an arc shape, the lock member 66 rotates smoothly when the operating portion 66b is rotated to rotate the lock member 66. In the drawing, the center of the arc on the front end surface of the lock body 66a is the center of the mounting hole 66d (the rotation center of the lock member 66).

[0055] Therefore, when an acting force F is applied to main frame hinge pin 622 in a direction that causes it to slip out along the inclination of bearing groove 63 formed in a L-shape and comes into contact with the arc-shaped front end surface of lock body 66a, when the acting force F is divided into a component force F1 (in the direction normal to the arc of the front end surface of lock body 66a) acting on the abutment portion between main frame hinge pin 622 and the arc-shaped front end surface, and a component force F2 acting on the abutment portion between main frame hinge pin 622 and one inner surface of bearing groove 63, the direction of component force F1 is directed toward the center of mounting hole 66d (mounting screw 67) (rotation center of lock member 66), so that no moment acts to rotate the front end of lock body 66a of lock member 66 in a direction away from right-side hanging portion 65, and the state in which main frame hinge pin 622 is sandwiched between the front end of lock body 66a of lock member 66 and one inner surface of bearing groove 63 is maintained.

[0056] Therefore, even in a normal journal state or when the acting force of the main frame hinge pin 622 is applied to the locking member 66, no load is constantly applied to the elastic portion 66c of the locking member 66, preventing plastic deformation due to creep of the elastic portion 66c which is integrally formed from a synthetic resin, and preventing the main frame hinge pin 622 from falling off from the bearing groove 63 over a long period of time. Even if an excessive force is applied and the front end portion of the locking body 66a of the locking member 66 is rotated in a direction moving rightward, the front right side surface of the locking body 66a abuts against the hanging portion 65 and does not rotate any further, so that the locking member 66 does not protrude outside the forward extension portion 62.

[0057] Furthermore, even if the shape of the front end face of locking body 66a is not arc-shaped, by positioning the center of rotation of locking member 66 (the axis fixed by mounting screws 67) at a position where no rotational moment is generated by the action of the above-mentioned component force F1 or at a position where a rotational moment is generated that rotates the front end of locking member 66 toward the outside of forward extension portion 62, no load is applied to elastic portion 66c of locking member 66 at all times, and even if locking member 66 rotates, the right side surface of the front end of locking body 66a only comes into contact with hanging portion 65, so that locking member 66 does not protrude outside forward extension portion 62.

[0058] When the main frame upper hinge pin 622 of the main frame upper hinge member 620 is supported in the bearing groove 63 of the outer frame upper hinge member 60, the main frame upper hinge pin 622 is inserted into the bearing groove 63 from the open side of the bearing groove 63. When the main frame upper hinge pin 622 is inserted into the bearing groove 63, the main frame upper hinge pin 622 abuts against the right side surface of the lock body 66a of the lock member 66, and the lock member 66 rotates about the mounting screw 67 so that the front end of the lock body 66a moves leftward against the biasing force of the elastic portion 66c. As a result, the lock body 66a that had been closing the bearing groove 63 retreats, opening the bearing groove 63, and the main frame upper hinge pin 622 can be moved to the deepest part (front end) of the bearing groove 63.

[0059] When the main body frame upper hinge pin 622 is moved to the deepest part of the bearing groove 63, the abutment between the main body frame upper hinge pin 622 and the lock body 66a of the lock member 66 is released, and the lock member 66 rotates so that the front end of the lock body 66a moves rightward due to the biasing force of the elastic part 66c, and the lock member 66 returns to its normal state. As a result, the main body frame upper hinge pin 622 is accommodated in the space in front of the front end of the lock body 66a in the bearing groove 63, and the main body frame upper hinge pin 622 is held (locked) in a rotatable state in the deepest part of the bearing groove 63.

[0060] When removing the main body frame upper hinge pin 622 from the bearing groove 63, the operating portion 66b of the locking member 66 is operated to rotate the locking member 66 so that the front end of the locking body 66a moves leftward, and the locking body 66a is moved back from the bearing groove 63 against the biasing force of the elastic portion 66c. This brings the deepest part of the bearing groove 63 into communication with the opening, and the main body frame upper hinge pin 622 can be removed from the bearing groove 63.

[0061] [2-10. Anti-theft mechanism and ball jamming prevention mechanism at the outer frame lower hinge part] We will explain the anti-theft mechanism at the lower hinge member 70 on the outer frame side of the outer frame 2 in the pachinko machine 1 of this embodiment, and the ball trap prevention mechanism for preventing game balls from getting caught between the outer frame 2 and the main frame 4.

[0062] In the assembled state, the outer frame 2 has an outer frame side lower hinge member 70 attached to the left end of the upper surface of the top panel member 50 as viewed from the front. The horizontal portion 71 of the outer frame side lower hinge member 70 is attached in a state of being placed near the left end of the upper surface of the top panel member 50 and on the upper surface of the rearward extending portion 51. The top panel member 50 has a vertical wall portion 54 rising upward from the rear end of the upper surface. As a result, even if an illegal tool such as a piano wire is inserted into the rear side of the main frame 4 (pachinko machine 1) through the gap between the outer frame side lower hinge member 70 and the main frame side lower hinge member 640, the tip of the illegal tool abuts against the vertical wall portion 54 extending upward from the rear end of the upper surface of the top panel member 50, so that the illegal tool cannot be inserted any further to the rear side, and illegal acts can be prevented from being performed through the portion of the outer frame side lower hinge member 70.

[0063] In addition, since the upper end of the vertical wall portion 54 is provided with a return portion 55 extending forward, if an unauthorized tool abutting against the vertical wall portion 54 is bent upward, the return portion 55 can bend the tip of the unauthorized tool further forward, thereby preventing the unauthorized tool from being inserted into the rear side of the main frame 4 and reliably preventing unauthorized acts from being performed through the outer frame side lower hinge member 70.

[0064] Incidentally, when the rear end of the upper surface of the fascia board member 50 is provided with the vertical wall portion 54 extending upward, if a game ball falls onto the outer frame side lower hinge member 70 (horizontal portion 71) while the main frame 4 is open relative to the outer frame 2, the game ball on the horizontal portion 71 is not discharged rearward from the rear end of the horizontal portion 71 due to the presence of the vertical wall portion 54, so there is a risk of the game ball being pinched between the outer frame 2 and the main frame 4. In contrast, in this embodiment, the horizontal portion 71 of the outer frame side lower hinge member 70 and the rear extension portion 51 of the fascia board member 50 are provided with the discharge hole 74, left discharge hole 52, and right discharge hole 53 through which the game ball can pass, so that the game ball on the horizontal portion 71 of the outer frame side lower hinge member 70 can be discharged downward from the discharge hole 74, etc., and the pinching of the game ball between the outer frame 2 and the main frame 4 can be reduced.

[0065] Therefore, it is possible to prevent a game ball from being caught between the outer frame 2 and the main frame 4, which could lead to damage around the outer frame lower hinge member 70, or the main frame 4 not closing normally and creating a gap between the outer frame 2 and the main frame 4, which could then be used to commit fraud.

[0080] [3-1a. Door frame base] The door frame base 110 of the door frame base unit 100 in the door frame 3 will be described in detail mainly with reference to Figs. 31 to 33. The door frame base 110 has an outer shape in a front view that is formed in a quadrangle (rectangle) extending vertically. The door frame base 110 has a through hole 111 that penetrates from front to back and has an inner periphery shape in a front view that is formed in a substantially quadrangle extending vertically. The through hole 111 has an upper side and both left and right sides that form the inner periphery that are close to the outer periphery of the door frame base 110, respectively, and a lower side that forms the inner periphery is located at about 1 / 3 height in the vertical direction from the lower end of the door frame base 110. Therefore, the door frame base 110 is formed in a frame shape as a whole by the through hole 111 that penetrates from front to back. This door frame base 110 is integrally molded from synthetic resin.

[0081] The door frame base 110 is equipped with a handle mounting surface 112 formed in the lower right corner of the front surface when viewed from the front and inclined so that the left end side protrudes slightly forward more than the right end side, a cylinder mounting section 113 which is recessed from the rear surface toward the front near the right end when viewed from the front between the handle mounting surface 112 and the through hole 111 and to which the cylinder mounting sheet metal 213 of the opening / closing cylinder unit 210 is attached, a cylinder insertion hole 114 which penetrates from the front to the front in the cylinder mounting section 113 and through which the cylinder lock 211 of the opening / closing cylinder unit 210 is inserted, and a ball feeding opening 115 which penetrates from the front to the front on the left side of the cylinder insertion hole 114 and the handle mounting surface 112 when viewed from the front, allowing the entrance 251a and ball removal opening 251b of the ball feeding unit 250 to be exposed forward.

[0083] [3-1b. Reinforcement unit] The reinforcing unit 130 of the door frame base unit 100 will be described in detail with reference to Figures 31 and 33. The reinforcing unit 130 is attached to the rear side of the door frame base 110 to reinforce the door frame base 110 and increase the strength and rigidity of the door frame base 110 (door frame 3). The reinforcement unit 130 comprises an upper reinforcement plate 131 extending left and right and attached along the upper edge of the rear surface of the door frame base 110, a middle reinforcement plate 132 extending left and right and attached below the through opening 111 on the rear surface of the door frame base 110, a left reinforcement plate 133 extending up and down and attached along the left edge of the rear surface of the door frame base 110 when viewed from the front, a right reinforcement plate 134 extending up and down and attached along the right edge of the rear surface of the door frame base 110 when viewed from the front, and a locking engagement portion 135 attached to the rear surface of the right reinforcement plate 134 and with which the door frame hook 702 of the locking unit 700 engages.

[0084] In the reinforcement unit 130, both left and right ends of the upper reinforcing metal sheet 131 are connected and fixed to the upper ends of the left reinforcing metal sheet 133 and the right reinforcing metal sheet 134 with screws, and the left end of the middle reinforcing metal sheet 132 is connected and fixed to the left reinforcing metal sheet 133 with a screw. The right end of the middle reinforcing metal sheet 132 is connected and fixed to the right reinforcing metal sheet 134 via a cylinder mounting metal sheet 213 of the opening / closing cylinder unit 210, which will be described later. Therefore, the reinforcement unit 130 is formed into a frame shape by the upper reinforcing metal sheet 131, the middle reinforcing metal sheet 132, the left reinforcing metal sheet 133, the right reinforcing metal sheet 134, etc.

[0085] The upper reinforcing metal plate 131, the middle reinforcing metal plate 132, the left reinforcing metal plate 133, the right reinforcing metal plate 134, and the locking engagement portion 135 of the reinforcing unit 130 are each formed by appropriately bending a metal plate. The middle reinforcing metal plate 132 has a notch 132a penetrating from front to rear at a position corresponding to the upper tray passage opening 117 of the door frame base 110.

[0086] Although detailed illustrations of the reinforcement unit 130 are omitted, each of the upper reinforcement sheet metal 131, middle reinforcement sheet metal 132, left reinforcement sheet metal 133, and right reinforcement sheet metal 134 has a portion that is bent in the front-to-rear direction, and these portions increase the strength and rigidity of the unit while also preventing the intrusion of unauthorized tools such as piano wire or flathead screwdrivers from outside.

[0087] [3-1c. Door frame upper hinge part] The door-frame-side upper hinge member 140 of the door-frame base unit 100 will be described in detail mainly with reference to Figures 31 to 33 etc. The door-frame-side upper hinge member 140 comprises: a door-frame-upper hinge axis bracket 141 attached to the door-frame base 110 and having a pair of protruding pieces 141a spaced apart vertically; a cylindrical door-frame-upper hinge pin 142 which penetrates the pair of protruding pieces 141a of the door-frame-upper hinge axis bracket 141 and has an upper end which is inserted into a door-frame upper hinge hole 623 of the main-frame-side upper hinge member 620; a disk-shaped flange member 143 attached to a position between the pair of protruding pieces 141a on the door-frame-upper hinge pin 142; and a lock spring 144 which is interposed between the flange member 143 and the lower protruding piece 141a of the pair of protruding pieces 141a, through which the door-frame-upper hinge pin 142 is inserted, and which urges the door-frame-upper hinge pin 142 upward.

[0088] Although not shown, the door-frame upper hinge shaft bracket 141 has a flat mounting piece that connects the rear ends of a pair of protruding pieces 141a, and is formed in a U-shape that is open forward when viewed from the side. The door-frame upper hinge shaft bracket 141 has a mounting piece that connects the pair of protruding pieces 141a attached to the rear surface of the door-frame base 110 with a screw.

[0089] The portion (upper end) of the door-frame upper hinge pin 142 that protrudes upward from the upper protruding piece 141a is rotatably inserted into the door-frame upper hinge hole 623 of the main body-frame upper hinge member 620. Although not shown, the door-frame upper hinge pin 142 has a portion that protrudes downward from the lower protruding piece 141a that is bent in the horizontal direction. This bent portion abuts against the lower surface of the lower protruding piece 141a, thereby restricting the upward movement of the door-frame upper hinge pin 142.

[0090] The flange member 143 is an E-ring, and is inserted and held in a groove formed on the outer periphery of the upper door-frame hinge pin 142. The lock spring 144 is a coil spring that can be inserted through the upper door-frame hinge pin 142, with an upper end abutting the flange member 143 and a lower end abutting the lower protruding piece 141a. The lock spring 144 is interposed in a compressed state between the flange member 143 and the lower protruding piece 141a, and urges the upper door-frame hinge pin 142 upward via the flange member 143.

[0091] In the door-frame-side upper hinge member 140, the door-frame upper hinge pin 142 is biased upward by the lock spring 144, and the horizontally bent portion of the lower end of the door-frame upper hinge pin 142 abuts against the lower surface of the lower protruding piece 141a, restricting further upward movement. In this state, the upper end of the door-frame upper hinge pin 142 protrudes a predetermined amount above the upper surface of the upper protruding piece 141a.

[0092] When an operator holds the horizontally bent portion of the lower end of upper door-frame hinge pin 142 of door-frame-side upper hinge member 140 and pulls that portion downward against the biasing force of lock spring 144, upper door-frame hinge pin 142 can be moved downward as a whole, and the upper end of upper door-frame hinge pin 142 can be retracted below the upper surface of upper protruding piece 141a. Therefore, the upper end of upper door-frame hinge pin 142 of upper door-frame-side hinge member 140 can be inserted into upper door-frame hinge hole 623 of main body-frame-side upper hinge member 620 from below, and pulled out downward. As a result, by inserting the upper end of the door frame upper hinge pin 142 of the door frame side upper hinge member 140 into the door frame upper hinge hole 623 of the main frame side upper hinge member 620, the upper left end of the door frame 3 when viewed from the front can be supported so as to be hinged rotatable relative to the main frame 4.

[0093] In addition, the door-frame-side upper hinge member 140 has a portion of the door-frame-side upper hinge pin 142 supported by a pair of protruding pieces 141a of the door-frame-side upper hinge axis bracket 141 supported coaxially with a door-frame-side lower hinge pin 152 of the door-frame-side lower hinge member 150 described below. This allows the door frame 3 to be hingedly rotated relative to the main body frame 4 in a good condition by the door-frame-side upper hinge member 140 and the door-frame-side lower hinge member 150.

[0094] [3-1d. Door frame bottom hinge parts] The door-frame-side lower hinge member 150 of the door-frame base unit 100 will be described in detail mainly with reference to Figures 31 and 32. The door-frame-side lower hinge member 150 includes a door-frame-side lower hinge shaft bracket 151 having a flat extension piece 151a attached to the door-frame base 110 and extending forward, and a cylindrical door-frame-side lower hinge pin 152 (see Figures 21 and 22) protruding downward from near the front end of the extension piece 151a in the door-frame-side hinge shaft bracket.

[0095] The door-frame lower hinge shaft bracket 151 has a flat mounting piece (not shown) extending upward from the rear end of the flat extension piece 151a extending horizontally, and has a generally L-shaped overall shape in side view. The door-frame lower hinge shaft bracket 151 has a mounting piece (not shown) attached to the rear surface of the door-frame base 110 with a screw.

[0096] The lower end of the door-frame lower hinge pin 152 is formed in a truncated cone shape that narrows toward the bottom. The door-frame lower hinge pin 152 is rotatably inserted from above into a door-frame hinge hole 644 of a body-frame-side lower hinge member 640 in the body frame 4 described below. The door-frame lower hinge pin 152 is disposed coaxially with the door-frame upper hinge pin 142 of the door-frame-side upper hinge member 140.

[0097] This door-frame-side lower hinge member 150 can support the door frame 3 relative to the main body frame 4 so that the door frame 3 can rotate about the hinge when the door-frame-side lower hinge pin 152 is inserted into the door-frame hinge hole 644 of the main body-frame-side lower hinge member 640.

[0098] [3-1e. Door frame left side decorative board] The door frame left side decorative board 160 of the door frame base unit 100 will be described in detail mainly with reference to Figures 31 and 32. The door frame left side decorative board 160 is attached to the front side of the door frame base 110, on the left side of the through hole 111 when viewed from the front. The door frame left side decorative board 160 includes a door frame left side upper decorative board 161 that extends vertically from a height position lower than the speaker insertion hole 119 on the left side of the door frame base 110 when viewed from the front to a height near the center of the through hole 111 in the vertical direction, and a door frame left side lower decorative board 162 that extends vertically from a height position lower than the door frame left side upper decorative board 161 to a height approximately the same as the lower end of the upper tray passage hole 117.

[0099] The upper left side decorative board 161 and the lower left side decorative board 162 of the door frame left side decorative board 160 are provided with a plurality of LEDs 161a, 162a on the front surface thereof, each of which is capable of emitting light forward. These LEDs 161a, 162a are full-color LEDs.

[0100] The door frame left side decorative board 160 is located behind the door frame left side unit 530 described below when the door frame 3 is assembled, and by appropriately illuminating multiple LEDs 161a, 162a provided (mounted) on the front side, the left unit decorative lens member of the door frame left side unit 530 can be illuminated and decorated.

[0101] [3-1f. Glass unit mounting parts] The glass unit mounting member 170 of the door frame base unit 100 will be described in detail mainly with reference to Fig. 31(b) etc. The glass unit mounting member 170 is rotatably attached to the rear side of the door frame base 110 for detachably mounting the glass unit 190. The glass unit mounting member 170 has a disk-shaped base 171 that is rotatably attached around an axis extending forward and backward on the rear side of the door frame base 110, and a protruding portion 172 that protrudes in a rod-like shape from the base 171 in a direction perpendicular to the axis of rotation.

[0102] The glass unit mounting members 170 are rotatably mounted below the pair of speaker insertion openings 119 on the rear surface of the door frame base 110 and at positions outside the glass unit mounting portions 118 .

[0103] When the glass unit mounting member 170 is rotated so that the protrusion 172 protrudes upward from the base 171, the protrusion 172 is positioned outward from the glass unit mounting portion 118 of the door frame base 110 when viewed from behind, making it possible to insert the glass unit 190 into the glass unit mounting portion 118 of the door frame base 110 or remove the glass unit 190 from the glass unit mounting portion 118.

[0104] When the glass unit mounting member 170 is rotated so that the protrusion 172 protrudes downward from the base 171 with the glass unit 190 inserted into the glass unit mounting portion 118 of the door frame base 110, the protrusion 172 abuts against the rear side of the mounting piece 191a of the glass unit 190, restricting the upper part of the glass unit 190 from moving backward, and the glass unit 190 can be mounted to the door frame base 110.

[0105] In the glass unit mounting member 170, the protruding portion 172 protrudes from the disk-shaped base 171 rotatably attached to the door frame base 110, so that the center of gravity of the glass unit mounting member 170 is located within the protruding portion 172. For this reason, when the glass unit mounting member 170 is in a state in which it can rotate freely, the protruding portion 172 is stable in a state in which it protrudes downward from the base 171. In the glass unit mounting member 170, when the protruding portion 172 is in a rotation position in which it protrudes downward from the base 171, the protruding portion 172 restricts the rearward movement of the glass unit 190. Therefore, even if vibration or the like acts on the glass unit mounting member 170, the entire member does not rotate so that the protruding portion 172 protrudes upward from the base 171, and the restriction on the rearward movement of the glass unit 190 is not naturally released.

[0106] Furthermore, when removing the glass unit 190 from the door frame base 110, the glass unit mounting member 170 is rotated so that the protrusion 172 protrudes upward from the base 171, and the protrusion 172 is moved outward beyond the mounting piece 191a of the glass unit 190, which makes it possible to move the upper side of the glass unit 190 rearward and remove the glass unit 190 from the door frame base 110.

[0107] [3-1g.Handle mounting parts] The handle mounting member 180 of the door frame base unit 100 will be described in detail mainly with reference to Figures 31 to 33. The handle mounting member 180 is for mounting the handle unit 300 to the front surface of the door frame base 110. As shown in Figures 32 and 33, the handle mounting member 180 includes a cylindrical tube portion 181 extending in the front-rear direction, an annular flange portion 182 extending from the rear end of the tube portion 181 outward in a direction perpendicular to the axis of the tube portion 181, a plurality of (three in this example) protrusions 183 protruding into the tube portion 181 and extending over the entire axial length of the tube portion 181 and arranged at unequal intervals in the circumferential direction of the tube portion 181, and a plurality of reinforcing ribs 184 connecting the outer circumferential surface of the tube portion 181 and the front surface of the flange portion 182 and arranged in the circumferential direction of the tube portion 181.

[0108] The handle mounting member 180 is attached to the handle mounting seat 112 by screws with the rear surface of the flange portion 182 abutting against the front surface of the handle mounting seat 112 of the door frame base 110.

[0109] The cylindrical portion 181 is formed so that its inner diameter is slightly larger than the outer diameter of the base 301a of the handle base 301 in the handle unit 300. Of the three ridges 183, one is provided on the upper side of the cylindrical portion 181, and the remaining two are provided on the lower side of the cylindrical portion 181. These three ridges 183 are formed at positions corresponding to the three grooves 301c in the handle base 301. Therefore, the handle attachment member 180 can insert the base 301a of the handle base 301 into the cylindrical portion 181 only when the three ridges 183 and the three grooves 301c of the handle base 301 are aligned, and the rotational position of the handle base 301 (handle unit 300) relative to the door frame base 110 can be restricted.

[0110] Furthermore, since the axis of the tubular portion 181 of the handle mounting member 180 extends perpendicular to the rear surface of the flange portion 182, when the handle mounting member 180 is mounted to the inclined handle mounting seat surface 112 of the door frame base 110, the axis of the tubular portion 181 is tilted so that it extends forward to the right, and the handle unit 300 can be mounted to the door frame base 110 in a similarly inclined state.

[0111] [3-1h. Glass unit] The glass unit 190 of the door frame base unit 100 will be described in detail mainly with reference to Figs. 31 to 33 etc. The glass unit 190 closes the through-hole 111 of the door frame base 110 so that the rear can be seen from the front. The glass unit 190 includes a frame-shaped glass frame 191 that is larger than the inner peripheral shape of the through-hole 111 of the door frame base 110 and can be attached to the glass unit attachment portion 118, and two transparent glass plates 192 that close the inside of the frame of the glass frame 191 and have their outer peripheries attached to the glass frame 191. The two glass plates 192 are attached to the front end side and the rear end side of the glass frame 191, respectively, and are spaced apart from each other in the front and rear directions so that a space is formed between them (see Fig. 26 etc.).

[0112] The glass frame 191 has a pair of mounting pieces 191a extending outward in a flat plate shape from positions lower than the upper left and right corners when viewed from the front, and a band-shaped locking piece 191b protruding downward from the lower end and extending along the lower side. The mounting pieces 191a of the glass frame 191 are adapted to come into contact with the protruding portion 172 of the glass unit mounting member 170. The locking piece 191b is adapted to be insertable into the space between the door frame base 110 and the middle reinforcing metal plate 132 of the reinforcing unit 130 (see FIG. 26).

[0113] This glass unit 190 is attached to the door frame base 110 by inserting the locking piece 191b of the glass frame 191 from above into the gap between the door frame base 110 and the middle reinforcing sheet metal 132 of the reinforcing unit 130 from the rear side of the door frame base 110, abutting the front end of the glass frame 191 against the rear surface of the glass unit mounting portion 118 of the door frame base 110, and rotating the glass unit mounting member 170 so that the protrusion 172 of the glass unit mounting member 170 abuts against the rear surface of the mounting piece 191a of the glass frame 191.

[0114] When removing the glass unit 190 from the door frame base 110, the above-mentioned procedure can be reversed. In this way, the glass unit 190 is detachable from the door frame base 110.

[0115] [3-1i. Security cover] The security cover 200 of the door frame base unit 100 will be described in detail mainly with reference to Figures 31 to 33. The security cover 200 is attached to the rear side of the door frame base 110 so as to cover the lower part of the rear surface of the glass unit 190, and is made of a transparent synthetic resin. The security cover 200 includes a flat main body 201 having an outer periphery formed into a predetermined shape, a flat rear projection 202 projecting rearward along the outer periphery of the main body 201, and a pair of locking pieces 203 arranged spaced apart on the left and right, projecting forward beyond the main body 201, and capable of being locked to the rear side of the door frame base 110.

[0116] The main body 201 of the security cover 200 is formed so that its lower end protrudes downward from the lower end of the glass unit 190 when attached to the door frame base 110. The main body 201 is also formed so that its upper end is shaped to fit the lower end of the play area 5a of the play board 5 when assembled to the pachinko machine 1. In more detail, the upper end of the main body 201 is shaped to fit a part of the inner rail 1002, the out guide part 1003, a part of the lower right rail 1004, and the right rail 1005 of the component 1000 described later, and is formed so as not to protrude into the play area 5a when assembled to the pachinko machine 1.

[0117] The rear protrusion 202 is formed around the entire outer periphery of the main body 201. Therefore, the security cover 200 is formed by the main body 201 and the rear protrusion 202 into a shallow box shape that is open to the rear, and has high strength and rigidity. In addition, as shown in Fig. 33, the rear protrusion 202 also protrudes rearward from a part of the rear surface of the main body 201 that is different from the outer periphery of the main body 201. The rear protrusion 202 protruding rearward from a part of the rear surface of the main body 201 is formed so as to fit along a part of the outer rail 1001 in the front component 1000 of the game board 5 when assembled to the pachinko machine 1.

[0118] In addition, the rear protrusion 202 is not formed in a portion of the game board 5 located between the outer rail 1001 and the inner rail 1002 when assembled to the pachinko machine 1. As a result, a game ball (a game ball launched by the ball launcher 680) passing between the outer rail 1001 and the inner rail 1002 does not come into contact with the rear protrusion 202 of the security cover 200, and does not hinder the game ball from being shot into the game area 5a.

[0119] The pair of locking pieces 203 are elastically locked to the rear side of the door frame base 110. This allows the security cover 200 to be easily attached to and detached from the door frame base 110.

[0120] When the security cover 200 is assembled to the pachinko machine 1, the front surface of the main body 201 abuts against the rear surface of the glass unit 190 (the rear end of the glass frame 191), and the rear projection 202, excluding the portion projecting rearward from the bottom edge of the main body 201, is inserted into the security recess 1008 of the front component 1000, which will be described later. Also, the security cover 200 is in a state in which the rear projection 202 projecting rearward from the bottom edge of the main body 201 projects rearward beyond the front surface of the front component 1000 so as to contact the bottom surface of the front component 1000. As a result, the area between the security cover 200 and the game board 5 (front component 1000) is complexly bent by the rear protrusion 202 of the security cover 200 and the security recess 1008 of the front component 1000, so that even if an attempt is made to insert an illegal tool such as a piano wire into the game area 5a between the security cover 200 and the front component 1000 from below the front of the game board 5, the attempt will be blocked by the rear protrusion 202 and the security recess 1008, preventing the illegal tool from entering the game area 5a.

[0121] [3-1j. Opening and closing cylinder unit] The opening / closing cylinder unit 210 of the door frame base unit 100 will be described mainly with reference to Figures 31 to 33. The opening / closing cylinder unit 210 is attached from the rear side to a cylinder attachment part 113 located near the right end of the door frame base 110 in a front view and between the through hole 111 and the handle attachment seat surface 112, and is used to open and close the door frame 3 and the main frame 4, and to open and close the outer frame 2 and the main frame 4 in cooperation with a locking unit 700 described later.

[0122] The opening / closing cylinder unit 210 comprises a cylindrical cylinder lock 211 which has a keyhole 211a on the front and extends forward and backward, a rotation transmission member 212 which is attached to the rear end of the cylinder lock 211 and transmits the rotation operation of the key inserted into the keyhole 211a to the key cylinder 710 of the locking unit 700, and a cylinder mounting sheet metal 213 which mounts the cylinder lock 211 to the door frame base 110 (reinforcement unit 130).

[0123] The cylinder lock 211 can be rotated by inserting a corresponding key (not shown) into the keyhole 211a, and if the key is a corresponding one, it can be rotated a specified angle in either a clockwise or counterclockwise direction when viewed from the front.

[0124] The rotation transmission member 212 is formed in a cylindrical shape (more specifically, a conical cylinder shape whose diameter increases toward the rear) with an open rear end, and has a pair of notches 212a cut from the rear end toward the front at positions facing each other across the central axis. This rotation transmission member 212 is formed so that the key cylinder 710 of the locking unit 700 in the main body frame 4 can be inserted from the rear, and by inserting the protrusions of the key cylinder 710 of the locking unit 700 into the pair of notches 212a, the rotation of the rotation transmission member 212 (the key inserted in the keyhole 211a of the cylinder lock 211) can be transmitted to the key cylinder 710 of the locking unit 700 to rotate the key cylinder 710.

[0125] The cylinder mounting sheet metal 213 is formed by bending a single metal plate, and is formed into a convex shape that protrudes forward when viewed from above. In detail, the cylinder mounting sheet metal 213 includes a rectangular flat front plate portion 213a extending vertically when viewed from the front, a pair of side plate portions 213b extending rearward in a flat plate shape from both left and right sides of the front plate portion 213a, and a pair of mounting plate portions 213c extending flat from the respective rear sides of the pair of side plate portions 213b in a direction away from each other. The cylinder lock 211 penetrates the front plate portion 213a of the cylinder mounting sheet metal 213 from the rear at a position approximately in the center in the vertical direction, and the rear end of the cylinder lock 211 is attached to the rear surface of the front plate portion 213a. Of the pair of mounting plate portions 213c of the cylinder mounting metal sheet 213, the mounting plate portion 213c on the left side as viewed from the front is attached to the right end portion of the middle reinforcing metal sheet 132 of the reinforcement unit 130, and the mounting plate portion 213c on the right side as viewed from the front is attached to the right reinforcing metal sheet 134 of the reinforcement unit 130. In this way, the cylinder mounting metal sheet 213 connects the middle reinforcing metal sheet 132 and the right reinforcing metal sheet 134 of the reinforcement unit 130.

[0126] When the opening / closing cylinder unit 210 is assembled to the door frame base unit 100, the front end of the cylinder lock 211, which protrudes forward from the front plate portion 213a of the cylinder mounting sheet metal 213, is inserted into the cylinder insertion hole 114 from the rear side of the door frame base 110 and protrudes forward of the door frame base 110, and the front plate portion 213a and a pair of side plate portions 213b of the cylinder mounting sheet metal 213 are housed within the box-shaped cylinder mounting portion 113, which is open to the rear.

[0127] [3-4. Overall configuration of the production operation unit] The overall configuration of the production operation unit 400 in the door frame 3 will be described in detail mainly with reference to Figs. 34 to 41. Fig. 34(a) is a front view of the production operation unit in the door frame, and (b) is a right side view of the production operation unit. Fig. 35(a) is a perspective view of the production operation unit seen from the front, and (b) is a perspective view of the production operation unit seen from the back. Fig. 36 is an explanatory diagram of the production operation unit seen from the direction in which the central axis of the operation button extends. Fig. 37 is a cross-sectional view cut along line DD in Fig. 34(a), and Fig. 38 is a cross-sectional view cut along line EE in Fig. 34(b). Fig. 39(a) is a cross-sectional view cut along line FF in Fig. 34(b), and (b) is an enlarged view of part A in (a). Fig. 40 is an exploded perspective view of the production operation unit disassembled into main components and seen from the front, and Fig. 41 is an exploded perspective view of the production operation unit disassembled into main components and seen from the back. The performance operation unit 400 is attached to the front part of the center in the left-right direction when viewed from the front of the tray unit 320, and can be operated by the player by pressing it, and can also present performance images to the player.

[0128] The performance operation unit 400 comprises an operation button 410 which has a circular outer shape and the central part except for the outer periphery is formed to be transparent so that the player can press it to operate it, a frame-shaped frame unit 415 which surrounds the outer periphery of the operation button 410 and is attached to the performance operation unit mounting portion 326a of the dish unit cover 326, a decorative board unit 420 which is positioned rearward of the operation button 410 and is capable of lighting up and decorating the outer periphery of the operation button 410 and the frame unit 415, a base unit 430 which is attached to the rear of the frame unit 415 and has the operation button 410 and decorative board unit 420 attached to the front side, and a door frame side performance display device 460 which is attached to the base unit 430 so as to be visible from the player side through the operation button 410 and is capable of displaying performance images.

[0129] [3-4a. Operation buttons] The operation button 410 of the performance operation unit 400 will be described in detail mainly with reference to Figs. 39 to 42. Fig. 42(a) is an exploded perspective view of the operation button disassembled and seen from the front, and Fig. 42(b) is an exploded perspective view of the operation button disassembled and seen from the back. The operation button 410 is formed in a circular shape with a diameter slightly smaller than the vertical height of the dish unit 320, and the center side except for the outer periphery is formed transparent. The operation button 410 is equipped with a transparent button lens 411 formed in a curved surface shape (a part of a spherical shape) with a circular periphery and a central side bulging forward, an annular button frame 412 attached to the front side of the outer periphery of the button lens 411, and a cylindrical button base 413 attached to the rear side of the button frame 412 so as to sandwich the outer periphery of the button lens 411. The button frame 412 and the button base 413 are formed of a material that is difficult for light to pass through.

[0130] The button lens 411 is formed to have a substantially uniform thickness. The front side of the button lens 411 is formed to have a smooth curved surface without any unevenness. The button lens 411 includes a first button decorative part 411a that extends a predetermined length toward the center (inner side) in a state of being recessed from the back side in a W-shape in cross section at a position on the inner periphery side of the button frame 412 and is arranged in a row in the circumferential direction, and a plurality (six) of second button decorative parts 411b that extend on an axis toward the center in a state of being recessed from the back side in a circular arc shape in cross section at a position on the outer periphery side of the first button decorative part 411a and is arranged in a row within a predetermined angle range in the circumferential direction.

[0131] As shown in the figure, when assembled to the operating button 410, the first button decorative portion 411a of the button lens 411 extends from the inner circumference of the button frame 412 toward the center, with the groups on the left and right sides extending further toward the center than the groups on the top and bottom sides.

[0132] The multiple second button decorative parts 411b of the button lens 411 each extend in an arc shape on the same circumference, and three are formed on each of the left and right sides. These second button decorative parts 411b are formed so as to face the frame opening 412a of the button frame 412, and protrude forward so that their front sides are approximately on the same plane as the front surface of the button frame 412.

[0133] The button lens 411 has a lens effect that refracts light due to the W-shaped or arc-shaped cross-sectional unevenness formed on the back surface of the first button decorative part 411a and the second button decorative part 411b, so that the rear side cannot be seen clearly.

[0134] The button frame 412 is formed in an annular shape and has a plurality (six) of frame openings 412a penetrating in the front-rear direction and extending in an arc shape for a predetermined length in the circumferential direction. The six frame openings 412a are provided three on each of the left and right sides, corresponding to the six second button decorative parts 411b of the button lens 411. The button frame 412 has a plating layer with metallic luster on its surface.

[0135] The button base 413 includes: a substantially cylindrical main body portion 413a extending a short distance in the front-rear direction; an annular flange portion 413b protruding outward from the front end of the main body portion 413a; guide boss portions 413c protruding cylindrically rearward from the rear side of the flange portion 413b along the outer periphery of the main body portion 413a and arranged in a plurality (four) of substantially equal intervals in the circumferential direction; detection pieces 413d protruding rearward in a band-like shape from the rear side of the flange portion 413b along the outer periphery of the main body portion 413a and arranged in a plurality (three) of the circumferential direction; base openings 413e penetrating the flange portion 413b in the front-rear direction outside the main body portion 413a, extending a predetermined length along the outer periphery, and formed in a plurality (six) of the circumferential direction; and an inner extension portion 413f extending forward in a cylindrical shape from the front end of the main body portion 413a and narrowing inward (toward the center) at the front end so as to fit along the inner surface of the button lens 411.

[0136] The outer peripheral edge of the button lens 411 and the button frame 412 are attached to the outer peripheral surface of the inner extension portion 413f of the button base 413 and the front surface of the flange portion 413b. The four guide boss portions 413c are respectively arranged at positions corresponding to the four corners of the main body portion 413a in the circumferential direction. These four guide boss portions 413c are respectively slidably inserted into the holding holes 431b of the unit base 431 in the base unit 430. The three detection pieces 413d are arranged at approximately equal intervals in the circumferential direction of the main body portion 413a, with two on the upper side and one on the lower side. When the operation button 410 is pressed, these three detection pieces 413d are detected by the pressing detection sensor 440 of the base unit 430.

[0137] The six base openings 413e are provided on the left and right sides, three on each side, and correspond to the second button decorative part 411b of the button lens 411 and the frame opening 412a of the button frame 412. At the base opening 413e of the button base 413, the main body 413a and a part of the inner extension 413f are recessed inward from the outer periphery. The inner diameter of the front end of the inner extension 413f, which narrows inward, is approximately the same as the inner diameter of the button frame 412.

[0138] The operation button 410 has a front surface that bulges forward in a curved surface shape (a part of a roughly spherical surface), and is formed transparent, so that the display screen of the door frame side performance display device 460 arranged on the rear side can be seen from the front. The operation button 410 has four guide boss parts 413c slidably inserted into the holding holes 431b of the unit base 431 in the base unit 430, and is biased forward by the operation button spring 438 inserted into the holding hole 431b of the unit base 431. The operation button 410 is restricted from moving further forward by the front side of the outer periphery abutting against the frame unit 415 due to the biasing force of the operation button spring 438 of the base unit 430, and moves backward until the rear end abuts against the front surface of the base unit 430 by pressing against the biasing force of the operation button spring 438. When the operation button 410 is pressed and moved backward, at least one of the three detection pieces 413d is detected by the pressure detection sensor 440 of the base unit 430. When the pressure detection sensor 440 detects the detection piece 413d, it means that the operation button 410 has been operated.

[0139] In addition, when the performance operation unit 400 is assembled, the first button decorative portion 411a, which is formed around the entire circumference of the operation button 410 and extends from the inner end of the button frame 412 of the transparent button lens 411 toward the center, makes it difficult for the player to see the gap between the inner surface of the button base 413 and the operation button internal decorative member 432 of the base unit 430.

[0140] Furthermore, the front end opening of the cylindrical button base 413 of the operation button 410 is closed by the button lens 411 and the button frame 412, and the button frame 412 attached to the outer periphery of the button lens 411 forms a transparent portion through which the rear can be seen narrowing inward from the outer periphery relative to the outer diameter of the operation button 410. The presence of this button frame 412 also makes it difficult for the player to see the gap between the inner periphery of the button base 413 and the decorative member 432 inside the operation button of the base unit 430.

[0141] In addition, when the operation button 410 is assembled to the performance operation unit 400, the rear end of the cylindrical button base 413 (main body 413a) protrudes rearward from the front surface of the decorative board unit 420 through the inner periphery of the decorative board unit 420. This prevents light irradiated forward from the first LEDs 422a, 423a and the second LEDs 422b, 423b mounted on the operation button left outer decorative board 422 and the operation button right outer decorative board 423 of the decorative board unit 420 from leaking from the outside to the inside of the button base 413, and prevents light irradiated forward from the LEDs mounted on the operation button left inner decorative board 433, the operation button right inner decorative board 434, the operation button upper inner decorative board 435, and the operation button lower inner decorative board 436 of the base unit 430 from leaking from the inside to the outside of the button base 413. Therefore, the LEDs mounted on the first LED 422a, 423a and second LED 422b, 423b of the decorative board unit 420 and the internal decorative board 433 to the left of the operation button, the internal decorative board 434 to the right of the operation button, the internal decorative board 435 above the operation button, and the internal decorative board 436 below the operation button of the base unit 430 can prevent areas other than those intended for illumination decoration from being illuminated, thereby enabling the illumination decoration to look good.

[0142] [3-4b. Frame unit] The frame unit 415 of the performance operation unit 400 will be described in detail mainly with reference to Figures 39 to 41. The frame unit 415 is attached from the front side to the performance operation unit attachment part 326a of the dish unit cover 326 in the dish unit 320 so as to surround the outer periphery from the front side of the operation button 410, and decorates the outside of the operation button 410. The outer shape of the frame unit 415 is formed in a shape that matches the front end side of the performance operation unit attachment part 326a.

[0143] The frame unit 415 comprises a frame-shaped frame body 416 having a circular central opening 416a and attached to the performance operation unit mounting portion 326a of the dish unit cover 326 in the dish unit 320, a pair of translucent frame side lenses 417 attached to the frame body 416 from the rear side on both the left and right sides of the central opening 416a, and a translucent frame top lens 418 attached to the frame body 416 from the front side above the central opening 416a.

[0144] The frame body 416 includes a circular central opening 416a that is smaller in diameter than the outer diameter of the operation button 410 and penetrates from front to back, a plurality of (six) outer peripheral openings 416b that penetrate from front to back on both the left and right outer sides of the central opening 416a and extend in an arc shape along the periphery of the central opening 416a and are arranged in a row in the circumferential direction, and a cutout portion 416c that is cut out with a predetermined width on the upper front surface of the central opening 416a. The central opening 416a is formed to have approximately the same size as the diameter of the outer peripheral side of the frame opening 412a of the button frame 412 in the operation button 410. This allows the front end side of the flange portion 413b of the button base 413 in the operation button 410 to abut against the outer peripheral rear side of the frame opening 412a.

[0145] The six outer peripheral openings 416b are provided on both the left and right outer sides of the central opening 416a, three on each side, and are closed from the rear by frame side lenses 417. The cutout portion 416c also penetrates in the front-rear direction, and a frame top lens 418 is fitted into it from the front.

[0146] The frame body 416 also has a generally cylindrical inner tube portion 416d extending rearward from a position slightly outside the periphery of the central opening 416a. The inner tube portion 416d extends rearward from a position between the central opening 416a and the outer peripheral opening 416b, and is cut out at a portion corresponding to the cutout portion 416c. When the performance operation unit 400 is assembled, the inner tube portion 416d is located between the first LEDs 422a, 423a and the second LEDs 422b, 423b on the operation button left outer decorative board 422 and the operation button right outer decorative board 423 of the decorative board unit 420, and separates the first LEDs 422a, 423a from the second LEDs 422b, 423b (see FIG. 38).

[0147] Furthermore, the frame main body 416 has a pair of mounting portions 416e which extend outward at the upper left and right sides of the outer periphery and are attached to the performance operation unit mounting portion 326a of the dish unit cover 326 of the dish unit 320. The frame main body 416 (performance operation unit 400) has the pair of mounting portions 416e and the left and right sides of the cutout portion 416c which are attached to the performance operation unit mounting portion 326a of the dish unit cover 326 of the dish unit 320.

[0148] Frame body 416 has a plated layer with metallic luster formed on almost the entire surface, except for a region the same width as notch 416c on the opposite side to notch 416c (the side where frame top lens 418 is attached) across central opening 416a.

[0149] The frame side lenses 417 close the peripheral openings 416b, three of which are formed on each of the left and right sides of the frame main body 416, from the rear side. The front side of the frame side lenses 417 is formed as a smooth surface without any irregularities, and the rear side has multiple irregularities formed along the periphery of the central opening 416a (see Figures 39 and 46). The multiple irregularities refract light, making it impossible to see the rear side of the frame side lenses 417.

[0150] The frame top lens 418 has a substantially rectangular outer shape so that it can be fitted from the front into the notch 416c of the frame body 416. The front side of the frame top lens 418 is formed smoothly. In addition, the rear side of the frame top lens 418 has a plurality of rows of irregularities extending in a zigzag pattern along the periphery of the central opening 416a in the radial direction of the central opening 416a (see Figures 37 and 46). The multiple irregularities refract light, making it impossible to see the rear side of the frame top lens 418.

[0151] When the frame unit 415 is assembled into the performance operation unit 400, a pair of frame side lenses 417 are positioned in front of the second LEDs 422b, 423b on the operation button left outer decorative board 422 and the operation button right outer decorative board 423 of the decorative board unit 420, and the frame top lens 418 is positioned in front of the frame top lens decorative board 437 of the base unit 430, and each can be illuminated and decorated by the second LEDs 422b, 423b etc. mounted thereon.

[0152] [3-4c. Decorative circuit board unit] The decorative board unit 420 of the performance operation unit 400 will be described in detail mainly with reference to Figs. 39 to 43. Fig. 43 is an exploded perspective view of the decorative board unit of the performance operation unit as seen from the front. The decorative board unit 420 is attached to the front of the base unit 430 below the frame unit 415, and can illuminate and decorate the second button decorative part 411b of the operation button 410 and the frame side lens 417 of the frame unit 415, as well as impart vibration to the performance operation unit 400.

[0153] The decorative board unit 420 comprises a C-shaped board base 421 with an open upper side, a left outer decorative board for operation buttons 422 and a right outer decorative board for operation buttons 423 which are respectively attached to the front sides of the left and right sides of the board base 421, a vibration motor 424 attached to the lower front side of the board base 421, and a motor cover 425 attached to the front side of the board base 421 so as to cover the front side of the vibration motor 424.

[0154] The substrate base 421 is formed so that its inner circumference is slightly larger than the outer diameter of the cylindrical main body portion 413a of the button base 413 of the operation button 410, and its outer circumference is larger than the outer diameter of the flange portion 413b of the button base 413 and smaller than the outer diameter of the frame unit 415.

[0155] The operation button left outer decorative board 422 extends in an arc shape along the front surface of the board base 421. The operation button left outer decorative board 422 includes a plurality of first LEDs 422a mounted on the front surface along the inner circumference of the board base 421, and a plurality of second LEDs 422b mounted on the front surface of the board base 421 radially outward from the plurality of first LEDs 422a. The operation button right outer decorative board 423 extends in an arc shape along the front surface of the board base 421. The operation button right outer decorative board 423 includes a plurality of first LEDs 423a mounted on the front surface along the inner circumference of the board base 421, and a plurality of second LEDs 423b mounted on the front surface of the board base 421 radially outward from the plurality of first LEDs 423a. The operation button left outer decorative board 422 and the operation button right outer decorative board 423 are both white on the front and back surfaces.

[0156] Vibration motor 424 has an eccentric weight 424a attached to a rotation shaft, and can generate vibrations by rotating this weight 424a.

[0157] When the decorative board unit 420 is assembled to the performance operation unit 400, the rear end side of the cylindrical main body 413a of the button base 413 in the operation button 410 is inserted inside the board base 421. In addition, in the decorative board unit 420, the first LEDs 422a, 423a in the operation button left outer decorative board 422 and the operation button right outer decorative board 423 are located behind the second button decorative part 411b of the operation button 410, and the second LEDs 422b, 423b are located behind the frame side lens 417 of the frame unit 415. In addition, when assembled to the performance operation unit 400, the inner cylindrical part 416d of the frame unit 415 is located between the first LEDs 422a, 423a and the second LEDs 422b, 423b of the operation button left outer decorative board 422 and the operation button right outer decorative board 423 (see FIG. 38).

[0158] Therefore, the decorative board unit 420 can illuminate and decorate only the second button decorative portion 411b of the operation button 410 with light from the respective first LEDs 422a, 423a on the operation button left outer decorative board 422 and the operation button right outer decorative board 423, and can illuminate and decorate only the frame side lens 417 of the frame unit 415 with light from the respective second LEDs 422b, 423b.

[0159] In addition, the decorative board unit 420 can generate vibrations by rotating the weight 424a of the vibration motor 424, thereby causing the entire performance operation unit 400 to vibrate.

[0160] [3-4f. Effects of the production operation unit] The action and effect of the production operation unit 400 will be described in detail mainly with reference to Figs. 44 to 46. Fig. 44 is an explanatory diagram showing the state in which the operation button is pressed in the cross-sectional view of the production operation unit in Fig. 37. Fig. 45(a) is an explanatory diagram showing the part of the operation button that is cut out and hidden by the first button decoration part and button frame of the operation button in the view of the production operation unit seen from the direction in which the central axis of the operation button extends, and Fig. 45(b) is an explanatory diagram showing the part of the operation button that is hidden by the first button decoration part and button frame of the operation button in the cross-sectional view of the production operation unit. Fig. 46(a) is an explanatory diagram showing the appearance of the production operation unit in a perspective view seen from the front, and Fig. 46(b) is an explanatory diagram showing the appearance of the production operation unit seen from the direction in which the central axis of the operation button extends.

[0161] The presentation operation unit 400 of this embodiment can show the player presentation images according to the game state that changes as the game ball is hit into the game area 5a of the game board 5, and can also have the player operate the operation button 410 to participate in the presented presentation, thereby entertaining the player.

[0162] The overall height of the performance operation unit 400 is formed to be approximately the same as the height of the lower portion of the through-hole 111 of the door frame base 110 in the door frame base unit 100 of the door frame 3. The overall width of the performance operation unit 400 is also formed to be slightly larger than 1 / 3 of the overall width of the door frame 3. When viewed from the front, the performance operation unit 400 is disposed in the center in the left-right direction below the play area 5a (the through-hole 111 of the door frame base 110).

[0163] The performance operation unit 400 is attached to the performance operation unit attachment portion 326a of the dish unit cover 326 of the dish unit 320 at the upper portion of the frame body 416 of the frame unit 415. When the performance operation unit 400 is attached to the dish unit 320, a gap is formed between the lower surface of the leg portion 442a of the relay board cover 442, which forms the bottom surface, and the upper surface of the bottom plate portion 326i of the dish unit cover 326 of the dish unit 320. In other words, only the upper portion of the performance operation unit 400 is attached to the dish unit 320, and it is attached in a suspended state.

[0164] In addition, the performance operation unit 400 is attached so that the front surface of the frame unit 415 (the surface formed by the inner periphery of the front end of the central opening 416a of the frame body 416) is parallel to the inclined surface of the front end opening of the performance operation unit attachment part 326a. As a result, the performance operation unit 400 is inclined so that the central axis CL of the transparent operation button 410, which bulges forward in a curved surface shape (the shape of a part of a roughly spherical surface), moves upward as it moves forward at an angle of 63 degrees with respect to the vertical line. As a result, when a player sits in front of this pachinko machine 1 to play a game using this pachinko machine 1, the player's head is located in front of the center of the play area 5a of the game board 5 located above the plate unit 320 (performance operation unit 400), so that the central axis CL of the operation button 410 passes near the player's head. Therefore, when a player drops his / her gaze from the game area 5a to the performance operation unit 400 (operation button 410), the operation button 410 will be seen as close as possible to its front view (projected view from a direction parallel to the central axis CL), and the operation button 410 and the door frame side performance display device 460 within the operation button 410, etc., can be viewed in good condition.

[0165] In the performance operation unit 400, the four guide boss portions 413c of the operation button 410 are slidably inserted into the four holding holes 431b of the base unit 430, respectively, and are biased forward by the operation button spring 438. In the performance operation unit 400, in the normal state (state in which the operation button 410 is not pressed), the biasing force of the operation button spring 438 causes the front end of the flange portion 413b of the button base 413 of the operation button 410 to abut against a portion near the central opening 416a on the rear surface of the frame main body 416 of the frame unit 415.

[0166] In the normal state of the performance operation unit 400, the central side (the central axis CL side) from the vicinity of the inner circumference of the button frame 412 of the operation button 410 protrudes forward from the central opening 416a of the frame main body 416 of the frame unit 415. In other words, in the transparent button lens 411 that bulges forward in a curved surface shape (the shape of a part of a substantially spherical surface) of the operation button 410, the part that protrudes forward from the inner circumference (inside) of the button frame 412 protrudes forward from the central opening 416a of the frame main body 416 of the frame unit 415 (see FIG. 37, etc.).

[0167] Incidentally, in this embodiment, the diameter of the central opening 416a of the frame body 416 in the frame unit 415 is approximately 15 cm, and the button lens 411 (front end) protrudes approximately 4 cm forward from the front surface of the frame unit 415 in the direction of the central axis CL of the operation button 410.

[0168] In a normal state, when a player presses the operation button 410 of the performance operation unit 400, the operation button 410 moves backward along the central axis CL against the biasing force of the operation button spring 438. Then, when the rear end of the operation button 410 abuts against the front surface of the unit base 431 of the base unit 430, the backward movement of the operation button 410 is restricted and the backward movement of the operation button 410 stops. When the player presses the operation button 410, he presses the button lens 411 that bulges forward in a curved surface shape (the shape of a part of a roughly spherical surface).

[0169] This operation button 410 has a very large outer diameter compared to the operation button for effect provided in a conventional pachinko machine, so there is a high possibility that the peripheral area away from the center of the button lens 411 will be pressed. In more detail, the operation button for effect in a conventional pachinko machine is attached so that its central axis extends approximately parallel to a vertical line, whereas the operation button 410 of the effect operation unit 400 of this embodiment is attached so that its central axis CL is inclined with respect to the vertical line. Therefore, when a player presses the operation button 410 from above as in a conventional pachinko machine, the player presses a part of the operation button 410 away from the central axis CL as shown by the outlined arrow in FIG.

[0170] Incidentally, in conventional pachinko machines, the operation buttons for effects in the game are formed on a flat surface that is pressed by the player. Therefore, if the operation button is made larger while keeping the part that is pressed on a flat surface, when a part that is not in the center of the operation button is pressed, the surface that is pressed will tilt so that the part that is pressed will recede first, and the operation button will no longer be able to recede in a straight line, which may make it impossible to press the operation button.

[0171] In contrast, the operation button 410 of the production operation unit 400 of this embodiment has a curved surface (a part of a substantially spherical surface) that bulges forward at the part (button lens 411) that the player presses, so when a position away from the center of the operation button 410 is pressed, the force is distributed over the entire operation button 410, making it difficult for the operation button 410 to tilt, and the operation button 410 can move straight backward. Therefore, no matter where the front side of the operation button 410 is pressed, the operation button 410 can move backward smoothly without tilting, so that the pressing operation can be reliably detected, and the performance of pressing the operation button 410 can be fully enjoyed.

[0172] In addition, the vibration motor 424 is attached to the lower front part of the board base 421 in the decorative board unit 420, and as described above, only the upper part of the performance operation unit 400 is attached to the performance operation unit attachment part 326a of the dish unit cover 326 so that the performance operation unit 400 can be suspended. Therefore, when the weight 424a is rotated by the vibration motor 424 to generate vibration, the vibration occurs at the part farthest from the part where it is attached, so that the entire performance operation unit 400 can be vibrated greatly (strongly) and the vibration can be transmitted to the player who is touching the performance operation unit 400. In addition, since the vibration motor 424 is located directly under a position (the position of the white arrow in FIG. 44) where it is relatively easy for the player to press the operation button, a strong vibration can be transmitted to the player who is pressing the operation button 410, and the player can be surprised and enjoy the performance.

[0173] Furthermore, the performance operation unit 400 is attached to the dish unit cover 326 in a state of being suspended, and a gap is formed between the lower surface of the leg 442a of the relay board cover 442 forming the lower surface and the upper surface of the bottom plate portion 326i of the dish unit cover 326, so that when the operation button 410 is strongly pressed downward or struck, the mounting portion 416e of the frame unit 415 and the performance operation unit mounting portion 326a of the dish unit cover 326, etc., bend downward to absorb the impact until the lower surface of the leg 442a abuts against the upper surface of the bottom plate portion 326i. In addition, after the lower surface of the leg 442a abuts against the upper surface of the bottom plate portion 326i, the downward movement of the performance operation unit 400 is restricted, and excessive force is prevented from acting on the mounting portion 416e of the frame unit 415 and the performance operation unit mounting portion 326a of the dish unit cover 326, etc., and damage to the performance operation unit 400, etc. can be prevented. Therefore, even if the operation button 410 is pressed or hit with great force when a performance in which the operation button 410 of the performance operation unit 400 is presented to the player, the operation button 410 and the performance operation unit 400 will not be damaged, so that interruption of the game due to damage can be avoided, and a decrease in the player's interest can be suppressed. Furthermore, by making the device less susceptible to damage, an increase in the burden on the gaming hall can be suppressed.

[0174] As described above, the button lens 411 of the operation button 410 that the player presses is formed into a curved surface (the shape of a part of an approximately spherical surface) that protrudes forward. This makes it stronger and more rigid than if it were flat. Even if it is hit hard, the impact can be dispersed throughout the entire button lens 411, making it less likely to break.

[0175] As shown in Fig. 46, the button lens 411, frame side lens 417, frame top lens 418, and operation button interior decorative member 432 are made of transparent materials in the performance operation unit 400, so that the decorations with unevenness such as the first button decoration part 411a, the second button decoration part 411b, the first button interior decorative part 432f, and the second button interior decorative part 432g formed on the back side of them can be seen from the front side (the player side). Also, in the areas where the uneven decorations are formed, the plate thickness changes and light refracts in a complex manner, so it is difficult to see the back side through the areas where the uneven decorations are formed.

[0176] The performance operation unit 400 includes a first button decoration part 411a extending from the inner circumference of the button frame 412 in the button lens 411 of the operation button 410 toward the center, and the uneven decoration of the first button decoration part 411a makes it difficult to see behind the outer periphery of the part inside the button lens 411. Behind the part where the first button decoration part 411a is formed (behind the direction of the central axis CL), there is a gap between the inner periphery of the main body part 413a of the button base 413 of the operation button 410 and the outer periphery of the peripheral wall part 432a of the operation button inner decoration member 432, but the first button decoration part 411a located in front of the gap makes it difficult to see the gap on the outer periphery of the operation button inner decoration member 432 from the front side (player side). As a result, even if an operation button 410 that can be operated by pressing is provided with an operation button interior decorative member 432 whose position is fixed, it is possible to prevent the appearance of the operation button 410 from deteriorating, and it is possible to prevent a player from feeling uncomfortable when looking at the operation button 410, and it is also possible to position the operation button interior decorative member 432 without any problems inside the transparent operation button 410, thereby improving the appearance of the operation button 410.

[0177] In detail, the production operation unit 400 is formed such that the unit base 431 and the decorative board unit 420, which are located outside the outer periphery of the decorative member 432 inside the operation button of the base unit 430 and on the rear side (back side) are not visible from the player side through the transparent button lens 411 by the first button decorative part 411a, the second button decorative part 411b, and the button frame 412 of the button lens 411 in the operation button 410. Specifically, in FIG. 45, the cross-hatched part surrounded by the dashed line is not visible from the player side. In this way, since the operation button 410 is provided with the first button decorative part 411a, the second button decorative part 411b, and the button frame 412, the outside and back side of the decorative member 432 inside the operation button can be hidden and made difficult to see, and the appearance of the operation button 410 and the production operation unit 400 as a whole can be improved.

[0178] In addition, in the performance operation unit 400, the first button decorative portion 411a of the button lens 411 in the operation button 410 extends toward the central axis CL of the operation button 410 and is arranged in a circumferential direction, while the second button inner decorative portion 432g formed on the front plate portion 432b of the operation button inner decorative member 432 arranged on the inside rear of the operation button 410 extends in a modified octagonal shape centered on the central axis CL and is arranged in a concentric row. Therefore, as shown in Figure 46, the concave and convex lines of the first button decorative portion 411a and the concave and convex lines of the second button inner decorative portion 432g intersect, allowing the player to see a geometric decoration.

[0179] In addition, since the first button decorative part 411a and the second button inner decorative part 432g of the performance operation unit 400 are separated in the front-to-back direction (the direction in which the central axis CL extends), the first button decorative part 411a and the second button inner decorative part 432g can present the player with a geometric pattern that gives a three-dimensional feel with depth, allowing the player to enjoy the decoration including the inside of the operation button 410.

[0180] Furthermore, in the performance operation unit 400, the first button decorative part 411a and the second button inner decorative part 432g are separated in the front-to-back direction, so that when the player's eye position moves, the degree of overlap between the concave-convex lines of the first button decorative part 411a and the concave-convex lines of the second button inner decorative part 432g changes, allowing the player to see a moving decoration and entertaining the player.

[0181] In this way, the performance operation unit 400 can present the player with a dynamic, three-dimensional decoration through the first button decorative portion 411a of the operation button 410 and the second button internal decorative portion 432g of the operation button internal decorative member 432, thereby strongly attracting the player's attention and making the pachinko machine 1 highly appealing.

[0182] In addition, in the operation button 410 (inside the button frame 412), the operation button left interior decorative board 433, the operation button right interior decorative board 434, the operation button upper interior decorative board 435, and the operation button lower interior decorative board 436 are arranged behind the operation button interior decorative member 432, and by illuminating the multiple LEDs mounted on the front of them, the operation button interior decorative member 432 in the operation button 410 can be illuminated and decorated. In other words, the operation button left interior decorative board 433, the operation button right interior decorative board 434, the operation button upper interior decorative board 435, and the operation button lower interior decorative board 436 can illuminate and decorate the inside of the operation button 410. The LEDs mounted on the front of the left operation button inner decorative board 433, the right operation button inner decorative board 434, the upper operation button inner decorative board 435, and the lower operation button inner decorative board 436 are positioned inside the cylindrical main body portion 413a of the button base 413 of the operation button 410 when viewed from the direction in which the central axis CL extends, as shown in Figure 38, so that light from them does not leak outside the main body portion 413a, and only the inside of the operation button 410 can be illuminated and decorated well.

[0183] In addition, in the performance operation unit 400, a first LED 422a of the operation button left outer decorative board 422 and a first LED 423a of the operation button right outer decorative board 423 in the decorative board unit 420 are arranged behind the second button decorative part 411b facing through the frame opening 412a of the button frame 412 located near the outer periphery of the operation button 410, and by illuminating these first LEDs 422a, 423a, the six second button decorative parts 411b of the operation button 410 can be illuminated and decorated. The first LED 422a of the left operation button outer decorative board 422 and the first LED 423a of the right operation button outer decorative board 423 are located between the cylindrical main body portion 413a of the button base 413 of the operation button 410 and the cylindrical inner tube portion 416d of the frame main body 416 of the frame unit 415, as shown in Figure 38, so that light from the first LEDs 422a, 423a does not leak inside the main body portion 413a or outside the inner tube portion 416d, and only the second button decorative portion 411b of the operation button 410 can be illuminated and decorated well.

[0184] Furthermore, in the performance operation unit 400, the second LED 422b of the left outer decorative board 422 of the operation button and the second LED 423b of the right outer decorative board 423 of the operation button are arranged behind the frame side lens 417 facing from the six outer peripheral openings 416b of the frame main body 416 in the frame unit 415, and the frame side lens 417 can be illuminated and decorated by illuminating the second LEDs 422b, 423b. The second LED 422b of the left outer decorative board 422 of the operation button and the second LED 423b of the right outer decorative board 423 of the operation button are located between the cylindrical inner tube portion 416d in the frame main body 416 of the frame unit 415 and the outer periphery of the frame main body 416, and the light from the second LEDs 422b, 423b does not leak to the inside of the inner tube portion 416d or the outside of the frame main body 416, and only the frame side lens 417 of the frame unit 415 can be illuminated and decorated well.

[0185] In addition, in the performance operation unit 400, the frame top lens decorative board 437 in the base unit 430 is disposed behind the frame top lens 418 of the frame unit 415, and the frame top lens 418 can be illuminated and decorated by illuminating a plurality of LEDs mounted on the front surface of the frame top lens decorative board 437. A flat light-shielding wall portion 431c protrudes forward from the lower side of the portion where the frame top lens decorative board 437 of the unit base 431 in the base unit 430 is attached to the frame top lens 418, and light from the LED of the frame top lens decorative board 437 does not leak to the operation button 410 or the frame side lens 417 side, and only the frame top lens 418 of the frame unit 415 can be illuminated and decorated well.

[0186] [3-5. Door frame left side unit] The door frame left side unit 530 of the door frame 3 will be described in detail mainly with reference to Figures 47 to 50. Figure 47(a) is a front view of the door frame left side unit in the door frame, (b) is a perspective view of the door frame left side unit seen from the front, and (c) is a perspective view of the door frame left side unit seen from the rear. Figure 48 is an exploded perspective view of the door frame left side unit seen from the front, and Figure 49 is an exploded perspective view of the door frame left side unit seen from the rear. Figure 50 is a cross-sectional view cut along the line LL in Figure 47(a). The door frame left side unit 530 is attached to the left of the through hole 111 in the front left part of the door frame base unit 100 so as to cover the front sides of the door frame left side upper decorative board 161 and the door frame left side lower decorative board 162 (door frame left side decorative board 160) above the plate unit 320. The door frame left side unit 530 is for decorating the left side of the through hole 111 of the door frame base 110 when viewed from the front.

[0187] The door frame left side unit 530 comprises a vertically extending strip-shaped left unit base 531 attached to the front of the door frame base 110 in the door frame base unit 100, on the left side of the through hole 111 as viewed from the front, a transparent strip-shaped left unit diffusion lens member 532 attached to the front of the left unit base 531, a translucent left unit decorative lens member (not shown) disposed in front of the left unit diffusion lens member 532 and having a polyhedral decoration at its front end, and a cylindrical frame-shaped member attached to the upper front surface of the left unit base 531 from the front side of the left unit decorative lens member. a left unit upper decorative base 534 extending vertically along the left unit upper decorative base 534, a left unit lower decorative base 535 attached to the lower front surface of the left unit base 531 from the front side of the left unit decorative lens member and protruding forward in a frame-like shape shorter than the left unit upper decorative base 534, a transparent left unit decorative cover 536 attached to the front side of the left unit base 531 from the front sides of the left unit upper decorative base 534 and the left unit lower decorative base 535 so as to cover the front end side of the left unit decorative lens member, and a plurality of decorative members 537 attached to the front side of the left unit decorative cover 536.

[0188] The left unit base 531 of the door frame left side unit 530 is formed in a shallow box shape with an open rear side, and has a plurality of openings 531a penetrating the front from front to back. As shown in the figure, the plurality of openings 531a include a circular hole and a rectangular hole extending vertically. The left unit base 531 is attached to the left side of the front of the door frame base 110 so that the LEDs 161a and 162a mounted on the front of the door frame left side decorative board 160 (the door frame left side upper decorative board 161 and the door frame left side lower decorative board 162) face forward from the plurality of openings 531a. Each opening 531a of the left unit base 531 is formed so that each LED 161a and 162a of the door frame left side decorative board 160 is located approximately in the center in the vertical direction when assembled to the door frame 3. This left unit base 531 is formed of an opaque material.

[0189] The left unit base 531 also has a left reflective standing wall 538 (see Figs. 5 and 23) that stands toward the front side from the glass plate 192 that is disposed so as to close the through hole 111. In the left reflective standing wall 538, the inner surface that is flat and faces the through hole 111 is provided as a reflective surface that can reflect light. The reflective surface can be provided by forming the inner surface of the left reflective standing wall 538 itself from a reflective material such as metal or resin, or by attaching a reflective sticker to the inner surface. As will be described later, the left reflective standing wall 538 is formed by the left unit base 531 and serves as a part (left side portion) of the above-mentioned reflective standing wall 33.

[0190] The left unit diffusion lens member 532 is formed of a transparent member and is divided into an upper diffusion lens member 532A and a lower diffusion lens member 532B. The left unit diffusion lens member 532 includes a circular lens portion 532a that is circular when viewed from the front and corresponds to the circular opening 531a in the left unit base 531, and a rectangular lens portion 532b that is rectangular when viewed from the front and corresponds to the rectangular opening 531a. The door frame left side unit 530 is formed so that the LEDs 161a and 162a of the door frame left side decorative board 160 are located immediately after the centers of the circular lens portion 532a and the rectangular lens portion 532b when assembled to the door frame 3.

[0191] The circular lens portion 532a of the left unit diffusion lens member 532 is formed in a convex lens shape with smooth front and rear surfaces. This circular lens portion 532a allows the light from the LEDs 161a and 162a arranged at the rear to be irradiated forward as a point. The light irradiated forward from this circular lens portion 532a allows the circular decorative portion of the left unit decorative lens member to be illuminated and decorated.

[0192] The rectangular lens portion 532b of the left unit diffusion lens member 532 comprises a central diffusion reflecting portion 532c that is conically recessed backward at the center of the front surface, a front diffusion lens portion 532d that is formed outside the central diffusion reflecting portion 532c on the front surface, an input lens portion 532e that bulges backward in a curved shape at the center of the rear surface (immediately after the central diffusion reflecting portion 532c), and a front reflection portion 532f that is outside the input lens portion 532e on the rear surface and is inclined generally so as to move forward as it moves away from the input lens portion 532e.

[0193] The front diffusion lens section 532d of the rectangular lens section 532b is formed by a plurality of concentric arc-shaped grooves divided in the circumferential direction by lines extending radially from the central diffusion reflection section 532c. More specifically, the front diffusion lens section 532d has a cross-sectional shape when cut along the radial direction, in which the grooves are recessed in an arc shape toward the rear, and the mountain parts between the grooves are bulged in an arc shape toward the front, forming a smooth wave-like front surface. The front diffusion lens section 532d is also formed such that the groove parts and mountain parts are alternately positioned in the circumferential direction on the boundary of the radially extending lines dividing the front diffusion lens section 532d in the circumferential direction.

[0194] The front reflecting portion 532f of the rectangular lens portion 532b is formed by a plurality of concentric arc-shaped grooves divided in the circumferential direction by lines extending radially from the input lens portion 532e. These grooves are V-shaped recessed from the rear to the front, and the deepest part is formed in an arc shape. The cross-sectional shape of the front reflecting portion 532f when cut along the radial direction is formed in a triangular shape with the mountain parts between the grooves pointed backward, and is formed in a saw-like shape. The front reflecting portion 532f is formed so that the grooves and mountain parts move forward as they move away from the center. In addition, the front reflecting portion 532f is formed so that the groove parts and mountain parts are alternately located in the circumferential direction with the line extending radially extending that divides the front reflecting portion 532f in the circumferential direction. The line extending radially that divides the front reflecting portion 532f in the circumferential direction coincides with the dividing line extending radially in the front diffusion lens portion 532d.

[0195] When this rectangular lens portion 532b is assembled to the door frame 3, the corresponding LEDs 161a, 162a of the door frame left side decorative board 160 are positioned immediately behind the input lens portion 532e.

[0196] In the rectangular lens portion 532b, the light irradiated forward from the LEDs 161a and 162a is input from the input lens portion 532e into the rectangular lens portion 532b. Since the input lens portion 532e bulges backward in a curved surface shape (convex lens shape), it can refract the light spreading forward from the LEDs 161a and 162a so that it travels parallel to the front, and guide almost all of the input light to the cone-shaped central diffuse reflection portion 532c. The light guided to the central diffuse reflection portion 532c is reflected by the inclined cone surface of the central diffuse reflection portion 532c so as to be diffused in a direction perpendicular to the axis extending forward and backward (a direction parallel to the front surface of the door frame left side decorative board 160), and travels from the center side to the outside along the front surface of the rectangular lens portion 532b. Furthermore, the light reflected by central diffuse reflecting portion 532c travels from the center to the outside (in a direction away from the center line of central diffuse reflecting portion 532c) over the entire thickness of rectangular lens portion 532b in the front-to-rear direction.

[0197] When the light reflected from the center to the outside in the rectangular lens portion 532b approximately parallel to the front surface of the door frame left side decorative board 160 reaches the sawtooth-shaped forward reflecting portion 532f, it is reflected forward by the surface of the forward reflecting portion 532f. At this time, the forward reflecting portion 532f is inclined so that the rear surface moves forward as it moves away from the central diffuse reflecting portion 532c, so that the thickness of the rectangular lens portion 532b in the front-rear direction becomes thinner as it moves away from the center (see FIG. 50). As a result, the light reflected outward over the entire thickness of the rectangular lens portion 532b in the front-rear direction at the central diffuse reflecting portion 532c can be sequentially reflected forward by the forward reflecting portion 532f as it moves from the center to the outside.

[0198] The light reflected forward by the front reflecting portion 532f passes through the front diffusion lens portion 532d and is irradiated forward from the rectangular lens portion 532b. At this time, since the cross section of the front diffusion lens portion 532d is formed in a wave shape, the light reflected forward by the front reflection portion 532f can be diffused in various directions, and the light can be irradiated forward (to the rear surface of the left unit decorative lens member) approximately uniformly from the front surface of the rectangular lens portion 532b.

[0199] In the front diffusion lens section 532d and the front reflection section 532f of the rectangular lens section 532b, the concentric grooves are divided by the radial lines, and the concentric grooves are shifted in the radial direction at the dividing lines so that the concentric grooves are arranged alternately in the circumferential direction. This makes it possible to prevent the light irradiated forward from the front surface of the rectangular lens section 532b from becoming a light with a concentric striped pattern of light and shade, and to irradiate light with a more uniform shade forward. This allows the multifaceted decorative section in front of the rectangular lens section 532b in the left unit decorative lens member to be illuminated and decorated approximately uniformly.

[0200] The left unit decorative lens member (not shown) is formed to fit the front surface of the left unit decorative cover 536. The left unit decorative lens member includes a circular decorative portion formed in a portion located in front of the circular lens portion 532a of the left unit diffusion lens member 532, and a polyhedral decorative portion formed in a portion located in front of the angular lens portion 532b of the left unit diffusion lens member 532. The circular decorative portion is formed in a shape having a plurality of triangular ribs in the circumferential direction on the outer periphery of a cylindrical portion that is recessed in the front surface and extends short in the front and rear directions. The polyhedral decorative portion is formed in a shape in which a plurality of quadrangular pyramid-shaped portions are arranged in the vertical direction on the front surface of a rectangular parallelepiped extending vertically, and a plurality of polyhedrons consisting of a plurality of triangles are arranged in the vertical direction on both the left and right sides of the rectangular parallelepiped portion. The circular decorative portion and the polyhedral decorative portion are formed in the same shape as the circular decorative portion 561a and the polyhedral decorative portion 561b of the right unit decorative lens member 561 in the door frame right side unit 550.

[0201] The left unit decorative lens member can be seen from the front side (player side) through the transparent left unit decorative cover 536. In addition, the circular decorative portion of the left unit decorative lens member is illuminated by light irradiated forward from the circular lens portion 532a of the left unit diffusing lens member 532, and the multifaceted decorative portion is illuminated by light irradiated forward from the rectangular lens portion 532b of the left unit diffusing lens member 532.

[0202] The left unit upper decorative base 534 is formed into a rectangular shape extending vertically when viewed from the front, and a square tube extending from front to back. The part of the left unit upper decorative base 534 that constitutes the lower surface on the outer periphery is inclined so that it protrudes downward as it goes from the front end to the rear end, and the lower part of that part is penetrated from front to back. This left unit upper decorative base 534 is formed from an opaque material.

[0203] The left unit lower decorative base 535 is formed in a U-shape when viewed from the front, which is open upward. The left unit lower decorative base 535 is inclined from the approximate center in the vertical direction at the front end to the rear end so that the upper side moves backward as it goes upward. This left unit lower decorative base 535 is formed of an opaque material.

[0204] The left unit decorative cover 536 extends vertically over the entire height of the door frame left side unit 530. The left unit decorative cover 536 is bent so that the vertical middle part is concave backward, and is composed of an L-shaped part whose lower part is bent backward so as to fit along the front end of the left unit upper decorative base 534, an L-shaped part whose upper part is bent backward so as to fit along the front end of the left unit lower decorative base 535, and a straight part connecting the lower end of the upper L-shaped part and the upper end of the lower L-shaped part.

[0205] The upper and lower ends of the left unit decorative cover 536 are attached to the front of the left unit upper decorative base 534 and the front of the left unit lower decorative base 535, respectively. This left unit decorative cover 536 is made of a transparent material, and the left unit decorative lens member arranged on the rear side can be seen from the front side.

[0206] The decorative members 537 extend vertically in short lengths and are attached at predetermined intervals in the vertical direction to the front surface of the left unit decorative cover 536. The decorative members 537 are made of an opaque material.

[0207] [3-6. Door frame right side unit] The door frame right side unit 550 of the door frame 3 will be described in detail mainly with reference to Figures 51 to 55.

[0209] The door frame right side unit 550 also comprises a transparent flat right unit right diffusion lens member 556 which is attached to the front side of the door frame right side decorative base plate 552 and to the right of the right unit left diffusion lens member 553 when viewed from the front, to the right of the center when viewed from the front on the front of the right unit base 551 and to the right of the right unit left diffusion lens member 553 when viewed from the front, and extends in the vertical and front-to-rear directions, a sheet-like right unit right decorative member 557 which is attached to the right side of the right unit right diffusion lens member 556 and is decorated, and a transparent flat right unit right cover 558 which is attached to the right unit right diffusion lens member 556 so as to cover the right side of the right unit right decorative member 557.

[0210] Furthermore, the door frame right side unit 550 is equipped with a shallow box-shaped, opaque right unit left shading member 559 that is positioned between the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556 and extends in the vertical and front-to-rear directions with the front and right sides open, and a flat, opaque right unit right shading member 560 that is attached to the left of the right unit right diffusion lens member 556 so as to close the open right side of the right unit left shading member 559.

[0211] The door frame right side unit 550 is provided with a right unit decorative lens member 561 having translucency, which is attached to the front ends of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556 and has a polyhedral decoration at the front end, a right unit decorative base 562 which is attached to the front of the right unit base 551 so as to cover both the left and right sides of the right unit decorative lens member 561 and the front end sides of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556, a transparent right unit cover 563 which is attached to the front side of the right unit decorative base 562 so as to close the front end opening of the right unit decorative base 562, and a plurality of decorative members 564 which are attached to the front side of the right unit cover 563. Although not shown in the drawings, the door frame right side unit 550 is provided with a connection cable which is attached to the right unit base 551 so as to penetrate vertically, and which connects the door main body relay board of the door frame base unit 100 and the door frame top unit relay board 589 of the door frame top unit 570.

[0212] The right unit base 551 of the door frame right side unit 550 has a rectangular shape when viewed from the front, a short rectangular tube shape when viewed from the front, and a box shape with a closed central portion in the front-to-rear direction. This right unit base 551 is made of an opaque material.

[0213] The right unit base 551 also has a right reflective standing wall portion 568 (see Figs. 6 and 24) that stands toward the front side from the glass plate 192 that is disposed so as to close the through hole 111. In the right reflective standing wall portion 568, the inner surface that is flat and faces the through hole 111 is provided as a reflective surface that can reflect light. As with the inner surface of the left reflective standing wall portion 538, the inner surface of the right reflective standing wall portion 568 itself can be made of a reflective material such as metal or resin, or the reflective surface can be provided by attaching a reflective sticker to the inner surface. As will be described later, the right reflective standing wall portion 568 is formed by the right unit base 551 and serves as a part (right side portion) of the above-mentioned reflective standing wall portion 33.

[0214] The door frame right side decorative board 552 is formed in a strip shape extending vertically. The door frame right side decorative board 552 is provided with a plurality of left LEDs 552a mounted on the left side of the center in the horizontal direction on the front surface, a right LED 552b mounted on the right side of the center in the horizontal direction on the front surface, and a plurality of middle LEDs 552c mounted in the center in the horizontal direction on the front surface.

[0215] The door frame right side decorative board 552 is formed in white on both the front and back sides. The door frame right side decorative board 552 is divided into an upper door frame right side upper decorative board 552A and a lower door frame right side lower decorative board 552B. Although not shown in the figure, the door frame right side lower decorative board 552B is connected to the door body relay board of the door frame base unit 100, and the door frame right side upper decorative board 552A is connected to the door frame right side lower decorative board 552B.

[0216] The right unit left diffusion lens member 553 comprises a flat main body portion 553a extending in the vertical and front-to-rear directions, a rear wall portion 553b protruding in a short flat shape from the rear edge of the main body portion 553a to the right when viewed from the front, multiple notches 553c cut out in a rectangular shape from the right end side of the rear wall portion 553b when viewed from the front to the left and formed at a predetermined interval in the vertical direction, a accommodating recess 553d that is shallowly recessed on the left surface side of the main body portion 553a when viewed from the front so that the right unit left decorative member 554 can be accommodated, input lens portions 553e protruding rearward from the rear end face of the main body portion 553a and provided in multiple vertical directions, and side reflecting portions 553f that are arranged in multiple vertical directions on the right surface side of the main body portion 553a when viewed from the front so that each input lens portion 553e is centered in the vertical direction.

[0217] The main body 553a of the right unit left diffusion lens member 553 is formed in a shape in side view in which the upper corner of the front end side of a vertically extending rectangle is notched obliquely in a C-chamfer shape, and the lower side is inclined so as to move upward as it moves forward. Also, as shown in Fig. 55, the main body 553a as a whole is slightly inclined with respect to the vertical line of the front surface of the door frame right side decorative board 552 so as to move to the right as viewed from the front as it moves forward from the rear end side. The front end of the main body 553a protrudes forward more than the front end of the door frame left side unit 530 when assembled to the door frame 3.

[0218] When assembled to the door frame right side unit 550, the right end of the rear wall portion 553b extends to approximately the center in the left-right direction of the right unit base 551. The left end of a rear wall portion 556b of the right unit right diffusion lens member 556 abuts against the right end of the rear wall portion 553b.

[0219] The multiple cutouts 553c are formed at predetermined intervals in the vertical direction, and some of them correspond to the middle LEDs 552c of the door frame right side decorative board 552. When assembled to the door frame right side unit 550, the middle LEDs 552c of the door frame right side decorative board 552 face forward from the multiple cutouts 553c, and the right unit decorative lens member 561 can be well illuminated and decorated by the multiple middle LEDs 552c.

[0220] The accommodating recess 553d has a flat bottom surface, and the shape of its outer periphery roughly matches the outer shape of the right unit left decorative member 554. This allows the right unit left decorative member 554 to be accommodated therein.

[0221] The input lens parts 553e protrude rearward at a predetermined interval in the vertical direction from the rear end surface of the main body part 553a. Specifically, they are formed at approximately the center in the vertical direction when the right unit left diffusion lens member 553 is divided into six equal parts in the vertical direction. Although detailed illustration is omitted, the input lens part 553e has a rectangular parallelepiped part with a rectangular shape extending vertically protruding rearward, and a part recessed forward from the rear surface of the rectangular parallelepiped part so as to curve spherically. These input lens parts 553e are each located immediately before the left LED 552a of the door frame right side decorative board 552 when assembled to the door frame right side unit 550. This allows the light from the left LED 552a to be input so as to be widely diffused within the main body part 553a.

[0222] A plurality (six) of side reflecting portions 553f are provided in the up-down direction. Each side reflecting portion 553f is formed by a plurality of concentric arc-shaped grooves divided in the circumferential direction by lines extending radially from the input lens portion 553e. In each of the concentric arc-shaped grooves, the surface closer to the input lens portion 553e is inclined with respect to the surface of the main body portion 553a, and the surface farther from the input lens portion 553e extends perpendicularly to the surface of the main body portion 553a, and the deepest part is formed in an arc shape. When cut in the radial direction centered on the input lens portion 553e, the side reflecting portion 553f is formed in a cross-sectional shape of a pointed triangle with the mountain portion between the grooves facing toward the center, and the whole is formed in a saw-like shape. In addition, the side reflecting portion 553f is formed such that the groove portion and the mountain portion are alternately arranged in the circumferential direction with the radial line dividing the plurality of concentric arc-shaped grooves in the circumferential direction as a boundary.

[0223] In this right unit left diffusion lens member 553, light irradiated forward from the left LED 552a of the door frame right side decorative board 552 is incident from the rear surface of the input lens portion 553e into the main body portion 553a of the right unit left diffusion lens member 553. Since the rear end of this input lens portion 553e is recessed in a curved shape toward the front, the light from the left LED 552a is refracted so as to spread due to the curved surface, and within the main body portion 553a, the light is diffused radially toward the front with each input lens portion 553e as the center.

[0224] Since the main body 553a is slightly inclined with respect to a line extending vertically from the front surface of the door frame right side decorative board 552 so that the main body 553a moves to the right as seen from the front as it moves forward, the light emitted from the left LED 552a mounted on the front surface of the door frame right side decorative board 552 and incident on the main body 553a from the input lens 553e hits the flat left surface inside the main body 553a. However, due to the angle of incidence with respect to the left surface of the main body 553a, the direct light from the left LED 552a is not emitted to the outside from the left surface of the main body 553a, but is reflected by the inner surface of the left surface toward the side reflector 553f.

[0225] Light incident forward from the input lens portion 553e into the main body portion 553a is reflected leftward as viewed from the front by hitting the sawtooth side reflecting portion 553f, and is irradiated outward from the left surface of the main body portion 553a. Note that light is also irradiated outward (rightward as viewed from the front) from the right surface (side reflecting portion 553f) of the main body portion 553a, but since the right unit left light shielding member 559 disposed on the right side of the main body portion 553a is a white member, the left surface of the right unit left light shielding member 559 is brightly illuminated, and the indirect light reflected by the right unit left light shielding member 559 passes through the main body portion 553a and is irradiated to the left side. Therefore, from the left surface of main body portion 553a, light reflected to the left by side reflecting portion 553f within main body portion 553a and light irradiated to the right from side reflecting portion 553f, reflected to the left by the left surface of right unit left shading member 559, and passed through main body portion 553a are irradiated to the left, so that right unit left decorative member 554 attached to the left side of main body portion 553a can be illuminated and decorated with good brightness.

[0226] In addition, in the side reflector 553f, the concentric grooves are divided by the radial lines, and the concentric grooves are shifted in the radial direction at the dividing lines so that the concentric grooves are arranged alternately in the circumferential direction, so that the light irradiated outward (leftward) from the left surface of the main body 553a is prevented from becoming a concentric striped light, and a more uniform light can be irradiated to the left. This allows the right unit left decorative member 554 housed in the housing recess 553d on the left surface of the main body 553a to be illuminated and decorated in a substantially uniform manner.

[0227] Since the right unit left diffusion lens member 553 is made of a transparent member, the pattern consisting of multiple concentric arc-shaped grooves and radially extending lines of the side reflecting portion 553f formed on the opposite side can be seen from the left side of the main body portion 553a when viewed from the front (the side where the storage recess 553d is formed). Therefore, if a transparent portion is formed in the right unit left decorative member 554, the pattern of the side reflecting portion 553f of the right unit left diffusion lens member 553 can be seen through the transparent portion, and the transparent portion of the right unit left decorative member 554 can be decorated by the side reflecting portion 553f.

[0228] The right unit left decorative member 554 is formed in a thin sheet shape, and is decorated with translucent decorations such as the manufacturer logo of the pachinko machine 1 and a logo that matches the concept of the presentation presented to the player on the game board 5. The right unit left cover 555 protects the outer surface of the right unit left decorative member 554 when assembled to the door frame right side unit 550.

[0229] The right unit right diffusion lens member 556 is formed substantially symmetrically with the right unit left diffusion lens member 553, and has a similar configuration. In detail, the right unit right diffusion lens member 556 includes a flat body portion 556a extending in the vertical and front-rear directions, a rear wall portion 556b protruding in a short flat shape from the rear side of the body portion 556a to the left as viewed from the front, a rectangular cutout portion 556c cut from the left end side of the rear wall portion 556b as viewed from the front to the right and formed in a plurality of predetermined intervals in the vertical direction, an accommodation recess 556d shallowly recessed on the right side of the body portion 556a as viewed from the front so as to be able to accommodate the right unit right decorative member 557, input lens portions 556e protruding rearward from the rear end surface of the body portion 556a and provided in the vertical direction in plurality, and side reflecting portions 556f arranged in the vertical direction in plurality on the left side of the body portion 556a as viewed from the front so that each input lens portion 556e is in the center in the vertical direction on the left side of the body portion 556a as viewed from the front.

[0230] The main body 556a of the right unit right diffusion lens member 556 is formed in a shape in side view in which the upper corner of the front end side of a rectangle extending vertically is cut obliquely in a C-chamfer shape, and the lower side is formed in a shape that is inclined so as to move upward as it moves forward, and is formed in approximately the same shape as the main body 553a of the right unit left diffusion lens member 553. Also, as shown in FIG. 55, the main body 556a is slightly inclined as a whole with respect to the vertical line of the front surface of the door frame right side decorative board 552 so that it moves leftward as viewed from the front as it moves forward from the rear end side. The front end of the main body 556a protrudes forward more than the front end of the door frame left side unit 530 when assembled to the door frame 3.

[0231] When assembled to the door frame right side unit 550, the left end of the rear wall portion 556b extends to approximately the center in the left-right direction of the right unit base 551. The right end of the rear wall portion 553b of the right unit left diffusion lens member 553 abuts against the left end of the rear wall portion 556b.

[0232] The multiple cutouts 556c are formed at a predetermined interval in the vertical direction, and some of them correspond to the middle LEDs 552c of the door frame right side decorative board 552. These multiple cutouts 556c are formed at positions corresponding to the multiple cutouts 553c of the right unit left diffusion lens member 553. Therefore, when assembled to the door frame right side unit 550, the cutouts 553c of the right unit left diffusion lens member 553 and the cutouts 556c of the right unit right diffusion lens member 556 form a square opening penetrating from the front to the back, and the middle LEDs 552c of the door frame right side decorative board 552 face forward from the opening, and the right unit decorative lens member 561 can be well illuminated and decorated by the multiple middle LEDs 552c.

[0233] The accommodating recess 556d has a flat bottom surface, and the shape of its outer periphery approximately matches the outer shape of the right unit right decorative member 557. This allows the right unit right decorative member 557 to be accommodated therein.

[0234] The input lens parts 556e protrude rearward at a predetermined interval in the vertical direction from the rear end surface of the main body part 556a. Specifically, they are formed at approximately the center of each of the right unit right diffusion lens member 556 when the right unit right diffusion lens member 556 is divided into six equal parts in the vertical direction. Although detailed illustration is omitted, the input lens part 556e has a rectangular parallelepiped part with a rectangular shape extending vertically protruding rearward, and a part recessed forward from the rear surface of the rectangular parallelepiped part so as to curve spherically. These input lens parts 556e are each located immediately before the right LED 552b of the door frame right side decorative board 552 when assembled to the door frame right side unit 550. This allows the light from the right LED 552b to be input so as to be widely diffused within the main body part 556a.

[0235] A plurality (six) of side reflecting portions 556f are provided in the up-down direction. Each side reflecting portion 556f is formed by a plurality of concentric arc-shaped grooves divided in the circumferential direction by lines extending radially from the input lens portion 556e. In each of the concentric arc-shaped grooves, the surface closer to the input lens portion 556e is inclined with respect to the surface of the main body portion 556a, and the surface farther from the input lens portion 556e extends perpendicularly to the surface of the main body portion 556a, and the deepest portion is formed in an arc shape. When cut in the radial direction centered on the input lens portion 556e, the side reflecting portion 556f has a cross-sectional shape formed in a pointed triangle shape with the mountain portion between the grooves facing toward the center, and the whole is formed in a saw-like shape. In addition, the side reflecting portion 556f is formed such that the groove portions and mountain portions are alternately arranged in the circumferential direction with the radial lines dividing the plurality of concentric arc-shaped grooves in the circumferential direction as the boundary.

[0236] In this right unit right diffusion lens member 556, light irradiated forward from the right LED 552b of the door frame right side decorative board 552 is incident from the rear surface of the input lens portion 556e into the main body portion 556a of the right unit right diffusion lens member 556. Since the rear end of this input lens portion 556e is recessed in a curved shape toward the front, the light from the right LED 552b is refracted so as to spread due to the curved surface, and within the main body portion 556a, the light is diffused radially toward the front with each input lens portion 556e as the center.

[0237] The main body 556a is slightly inclined with respect to a line extending vertically from the front surface of the door frame right side decorative board 552 so that the main body 556a moves to the left as seen from the front as it moves forward, so that the light emitted from the right LED 552b mounted on the front surface of the door frame right side decorative board 552 and incident on the main body 556a from the input lens 556e hits the flat right surface inside the main body 556a. However, due to the angle of incidence with respect to the right surface of the main body 556a, the direct light from the right LED 552b is not emitted to the outside from the left surface of the main body 556a, but is reflected by the inner surface of the right surface toward the side reflector 556f.

[0238] Then, the light incident forward from the input lens portion 556e into the main body portion 556a hits the sawtooth side reflecting portion 556f, is reflected to the right as viewed from the front, and is irradiated outward from the right surface of the main body portion 556a. Note that light is also irradiated outward (leftward as viewed from the front) from the right surface (side reflecting portion 556f) of the main body portion 556a, but since the right unit right light shielding member 560 arranged on the left side of the main body portion 556a is a white member, the right surface of the right unit right light shielding member 560 is brightly illuminated, and the indirect light reflected by the right unit right light shielding member 560 passes through the main body portion 556a and is irradiated to the right side. Therefore, from the right surface of main body portion 556a, light reflected to the right by side reflecting portion 556f within main body portion 556a and light irradiated to the left from side reflecting portion 556f, reflected to the right by the right surface of right unit right shading member 560, and passed through main body portion 556a are irradiated to the right, so that right unit right decorative member 557 attached to the right side of main body portion 556a can be illuminated and decorated with good brightness.

[0239] In addition, in the side reflector 556f, the concentric grooves are divided by the radial lines, and the concentric grooves are shifted in the radial direction at the dividing lines so that the concentric grooves are arranged alternately in the circumferential direction, so that the light irradiated outward (to the right) from the right surface of the main body 556a can be prevented from becoming a concentric striped light and shade, and a more uniform light can be irradiated to the right. This allows the right unit right decorative member 557 housed in the housing recess 556d on the right surface of the main body 556a to be illuminated and decorated in a substantially uniform manner.

[0240] Since the right unit right diffusion lens member 556 is made of a transparent member, the pattern consisting of multiple concentric arc-shaped grooves and radially extending lines of the side reflecting portion 556f formed on the opposite side can be seen from the right side of the main body portion 556a when viewed from the front (the side where the storage recess 556d is formed). Therefore, if a transparent portion is formed in the right unit right decorative member 557, the pattern of the side reflecting portion 556f of the right unit right diffusion lens member 556 can be seen through the transparent portion, and the transparent portion of the right unit right decorative member 557 can be decorated with the side reflecting portion 556f.

[0241] The right unit right decorative member 557 is formed in a thin sheet shape, and is decorated with a logo of the manufacturer of the pachinko machine 1, a logo according to the concept of the performance presented to the player on the game board 5, etc., so as to have translucency. The right unit right cover 558 protects the outer surface of the right unit right decorative member 557 when assembled to the door frame right side unit 550. The right unit right decorative member 557 and the right unit right cover 558 are formed approximately symmetrically with the right unit left decorative member 554 and the right unit left cover 555. The decorations applied to the right unit left decorative member 554 and the right unit right decorative member 557 may be the same decoration or different decorations.

[0242] The right unit left light shielding member 559 is formed in a shape in a side view that is substantially the same as the shape in a side view of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556. The right unit left light shielding member 559 is formed in a shallow box shape that is open in the front and right. The right unit left light shielding member 559 includes a flat body portion 559a extending in the up-down and front-rear directions, a rear wall portion 559b that protrudes in a short flat shape from the rear side of the body portion 559a to the right in a front view, a notch portion 559c that is notched in a rectangular shape from the right end side of the rear wall portion 559b in a front view to the left and is formed in a plurality of predetermined intervals in the up-down direction, and a plurality of flat reinforcing portions 559d that extend rightward from the right surface of the body portion 559a and extend from the rear wall portion 559b to the front end of the body portion 559a.

[0243] Main body portion 559a of right unit left shading member 559 has a shape when viewed from the side, with the upper corner of the front end side of a vertically extending rectangle being diagonally cut out in a C-chamfered shape, and the lower side is slanted so as to move upward as it moves forward, and is formed in approximately the same outer shape as main body portions 553a, 556a of right unit left diffusion lens member 553 and right unit right diffusion lens member 556.

[0244] When assembled to the door frame right side unit 550, the left end of the rear wall portion 559b extends to the right of approximately the center in the left-right direction of the right unit base 551. The left surface of the right unit right light blocking member 560 abuts against the right end of this rear wall portion 559b.

[0245] The multiple cutouts 559c are formed at predetermined intervals in the vertical direction, and some of them correspond to the middle LEDs 552c of the door frame right side decorative board 552. These multiple cutouts 559c are formed at positions corresponding to the multiple cutouts 553c, 556c of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556. Therefore, when assembled to the door frame right side unit 550, the middle LEDs 552c of the door frame right side decorative board 552 face forward from the multiple cutouts 559c, and the right unit decorative lens member 561 can be well illuminated and decorated by the multiple middle LEDs 552c.

[0246] The multiple reinforcing parts 559d are provided in three sets spaced a predetermined distance apart in the vertical direction, with each set being a pair of reinforcing parts 559d spaced apart in the vertical direction at approximately the same height as the left-right width. Each set of reinforcing parts 559d is formed in a position behind a decorative member 564 attached to the right unit cover 563. The multiple reinforcing parts 559d increase the overall strength and rigidity of the door frame right side unit 550.

[0247] The right unit right light shielding member 560 has a shape in side view in which the upper corner on the front end side of a vertically extending rectangle is notched obliquely in a C-chamfer shape and the lower side is formed in a shape that slopes upward as it moves forward, and is formed in approximately the same shape as the main body 559a of the right unit left light shielding member 559. When assembled to the door frame right side unit 550, the right unit right light shielding member 560 closes the right side opening that is open to the right of the right unit left light shielding member 559 that is formed in a shallow box shape.

[0248] The right unit left light shielding member 559 and the right unit right light shielding member 560 are each formed of a white material. As shown in Fig. 55, the right unit left light shielding member 559 and the right unit right light shielding member 560 are arranged such that their respective main bodies 559a and right unit right light shielding member 560 are adjacent to the main bodies 553a, 556a of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556 when assembled to the door frame right side unit 550. As a result, the main body 559a of the right unit left light shielding member 559 and the right unit right light shielding member 560 are spaced apart in the left-right direction, forming a space extending in the up-down and front-rear directions with a predetermined width in the left-right direction. Light emitted forward from the middle LED 552c of the door frame right side decorative board 552 is irradiated to the rear side of the right unit decorative lens member 561 through the space formed between the main body 559a of the right unit left shading member 559 and the right unit right shading member 560.

[0249] In addition, the right unit left shading member 559 and the right unit right shading member 560 are formed from an opaque material, preventing the light emitted forward from the left LED 552a, middle LED 552c, and right LED 552b on the door frame right side decorative board 552 from interfering with each other, and allowing the right unit left decorative member 554, right unit right decorative member 557, and right unit decorative lens member 561 to be illuminated and decorated only by the corresponding left LED 552a, right LED 552b, and middle LED 552c, respectively.

[0250] Furthermore, the right unit left light shielding member 559 and the right unit right light shielding member 560 have their internal spaces vertically divided into four by three sets of reinforcing parts 559d, so that the LEDs 552c in the door frame right side decorative board 552 arranged at the rear of each divided space can prevent light interference between the spaces, and the parts located in front of each space of the right unit decorative lens member 561 can be independently illuminated and decorated. In other words, the front end side of the door frame right side unit 550 can be vertically divided into multiple (four) regions, and each can be independently illuminated and decorated.

[0251] The right unit decorative lens member 561 is formed in a shape that follows the front end shape of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556. The right unit decorative lens member 561 includes a circular decorative part 561a that is circular in front view, and a polyhedral decorative part 561b that extends vertically and has multiple polyhedrons formed thereon. The circular decorative part 561a is formed in a shape that includes multiple triangular ribs in the circumferential direction on the outer periphery of a cylindrical part that is recessed on the front side and extends short in the front and rear directions. The polyhedral decorative part 561b is formed in a shape that includes multiple rows of quadrangular pyramid-shaped parts in the vertical direction on the front side of a rectangular parallelepiped that extends vertically, and multiple rows of polyhedrons made of multiple triangles on both the left and right sides of the rectangular parallelepiped part in the vertical direction.

[0252] In detail, the right unit decorative lens member 561 is formed so that, in the regions located in front of each of the spaces divided into four by three sets of reinforcing members 559d in the right unit left shading member 559, a plurality of circular decorative members 561a and a multifaceted decorative member 561b are arranged, one on each side of the top and bottom of the circular decorative member 561a located in the center in the vertical direction, in the top three regions, and in the bottommost region, only the multifaceted decorative member 561b is arranged.

[0253] The right unit decorative lens member 561 is attached to the front ends of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556. The right unit decorative lens member 561 can be seen from the front side (the player side) through the transparent right unit cover 563. This right unit decorative lens member 561 is illuminated and decorated by the LED 552c in the door frame right side decorative board 552 located at the rear.

[0254] The right unit decorative base 562 is formed in a cylindrical frame shape that penetrates in the front-rear direction. The right unit decorative base 562 is formed in a shape that follows the shape of the front end and the upper end of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556. The right unit decorative base 562 is formed so as to be able to cover both the left and right outer sides near the front end of the right unit left diffusion lens member 553 and the right unit right diffusion lens member 556, and both the left and right sides of the right unit decorative lens member 561. When assembled to the door frame right side unit 550, the front end of the right unit decorative lens member 561 protrudes slightly forward from the front end of the right unit decorative base 562. This right unit decorative base 562 is formed of an opaque member.

[0255] The right unit cover 563 is formed so as to be able to close the front end opening of the right unit decorative base 562. This right unit cover 563 is formed of a transparent member, and the right unit decorative lens member 561 arranged on the rear side can be visually confirmed from the front side.

[0256] The decorative members 564 extend vertically and are attached to the front surface of the right unit cover 563 at predetermined intervals in the vertical direction. The decorative members 564 are made of an opaque material. The three decorative members 564 divide the right unit cover 563 (right unit decorative lens member 561) into four parts in the vertical direction.

[0257] When assembled to the door frame 3, the door frame right side unit 550 protrudes forward in a plate shape farther forward than the door frame left side unit 530, and protrudes slightly forward than the front end of the upper plate 321 of the plate unit 320. The door frame right side unit 550 can independently illuminate and decorate the right unit left decorative member 554 and the right unit right decorative member 557 provided on both the protruding left and right sides, and the right unit decorative lens member 561 provided at the front end.

[0258] Since the door frame right side unit 550 is plate-shaped and protrudes forward, when the present pachinko machine 1 is installed in an island facility in a gaming hall, the door frame right side unit 550 can act as a partition between the pachinko machine adjacent to the right side. This gives the player playing the present pachinko machine 1 the illusion that he is playing in a private room, allowing him to play in a relaxed atmosphere without worrying about other players around him.

[0259] In addition, since the door frame right side unit 550 protrudes forward significantly, in a game hall where pachinko machines 1 are installed in a row, even if it is not located in front of the pachinko machine 1, it can be seen from the side along the island equipment, and the pachinko machine 1 can be made to stand out in a game hall where many pachinko machines are lined up. Therefore, if the right unit left decorative member 554 and the right unit right decorative member 557 on both the left and right sides of the door frame right side unit 550 are illuminated, the presence of the pachinko machine 1 can be made known from a distance even if it is not located near the front of the pachinko machine 1, and the pachinko machine 1 can be made to have a high appeal to players.

[0260] Furthermore, in the door frame right side unit 550, when a malfunction such as ball jamming or an error occurs in this pachinko machine 1, the right unit left decorative member 554, the right unit right decorative member 557, and the right unit decorative lens member 561 on both the left and right sides are illuminated and decorated in a unique manner, so that the occurrence of the malfunction can be immediately notified to the game hall staff and they can respond quickly to the malfunction, thereby quickly resolving the interruption of the player's play and preventing the player from becoming frustrated and losing interest in the game.

This allows the door frame top unit 570 to decorate the entire upper front surface of the door frame 3.

[0296] In this case, the door frame top unit 570 is provided with upper speakers 573 whose front faces are protected by speaker covers 575 made of punching metal, located behind each of the left and right ends where the top left decorative lens member 579 and the top right decorative lens member 580 are located, and the speaker covers 575 face forward from between the three decorative lens parts 579a, 580a that are spaced apart above and below the top left decorative lens member 579 and the top right decorative lens member 580, so that the player can hear the sounds output from the left and right upper speakers 573 in good condition and enjoy high-quality stereo sound.

[0297] Furthermore, the door frame top unit 570 can guide light from the door frame top left decorative board 583, the door frame top right decorative board 584, the door frame top middle left decorative board 586, and the door frame top middle right decorative board 587 to the top left decorative lens member 579 and the top right decorative lens member 580 by using a plurality of light guide members 578 provided on the rear side of the top left decorative lens member 579 and the top right decorative lens member 580, and can satisfactorily illuminate and decorate the entire front of the top left decorative lens member 579 and the top right decorative lens member 580. Therefore, the door frame top unit 570 can illuminate and decorate the entire front of the upper part of the door frame 3, including the front of the left and right upper speakers 573.

[0298] [3-8. Function and effect of door frames] The effect of the door frame 3 will be described. The door frame 3 in the pachinko machine 1 of this embodiment has a through hole 111 penetrating the front and rear of the door frame base 110 in the door frame base unit 100, which is larger in the vertical and horizontal directions than conventional pachinko machines, and in accordance with the enlargement of the through hole 111, the vertical height of the plate unit 320 and the door frame top unit 570 is reduced, and the horizontal width of the door frame left side unit 530 and the door frame right side unit 550 is reduced. This allows the front of the game board 5 (play area 5a) attached to the main body frame 4 to be seen as widely as possible from the player (front) through the through hole 111 (glass unit 190), corresponding to the game board 5 with a wide play area 5a.

[0299] The door frame 3 is provided with a performance operation unit 400 (second performance operation unit 400A) having a large hemispherical operation button 410 at the center of the left and right direction of the dish unit 320 bulging forward below the through hole 111, and the front surface (front surface of the dish front lower decorative part 326c) of the lower half (part lower than the upper dish 321) on both sides of the left and right of the performance operation unit 400 is formed in a concave shape (a concave curved shape so that the front surfaces on both sides of the performance operation unit 400 are located further back than the straight line connecting the front ends of both the left and right ends of the dish unit 320 and the front ends of both the left and right ends of the performance operation unit 400). As a result, the performance operation unit 400 attached to the front surface at the center of the left and right direction of the dish unit 320 looks like it is protruding forward, so that the performance operation unit 400 can be made to stand out and be emphasized to the player, and the performance operation unit 400 can be strongly drawn attention to it.

[0300] The door frame 3 is attached with the performance operation unit 400, which is located on the front side of the tray unit 320 below the through hole 111, tilted so that the large, semi-spherical, transparent operation button 410 faces diagonally upward and forward. Therefore, when a player sits in front of this pachinko machine 1, the operation button 410 faces the player's head (face), and when the player lowers his or her eyes to look at the performance operation unit 400, the operation button 410 appears to be almost directly ahead, allowing the large, round operation button 410 to be strongly visible and increasing anticipation for the performance using the operation button 410. At the same time, the performance image displayed on the door frame side performance display device 460, which is located within the transparent operation button 410, can be clearly seen, allowing the player to fully enjoy the performance image.

[0301] In addition, the door frame 3 is provided with a large operation button 410 that bulges forward in a round shape and has a diameter approximately equal to the overall height of the plate unit 320, so that when operating the operation button 410, any part of the operation button 410 can be touched by moving the hand a short distance, and the operation button 410 can be "quickly pressed" relatively easily. In addition, since the operation button 410 that bulges forward in a round shape and has a large diameter is attached in an inclined state, not only can it be pressed from above like the operation button of a conventional pachinko machine, but it can also be easily operated from the left, right, or front, and the easy-to-operate operation button 410 can make the performance using the operation button 410 more enjoyable.

[0302] In addition, the door frame 3 is attached with the performance operation unit 400 in a suspended state by the plate unit 320, and is equipped with a vibration motor 424 that generates vibrations at the bottom of the performance operation unit 400.Therefore, when the vibration motor 424 is rotated to generate vibrations depending on the game status, strong vibrations can be transmitted to the player's hand touching the top of the operation button 410, surprising the player and making the performance using the operation button 410 even more enjoyable.

[0303] Furthermore, the door frame 3 is equipped with a large operation button 410 (performance operation unit 400) that spans the entire height of the tray unit 320, in the center of the front surface of the tray unit 320, making the lower tray 322 located below the upper tray 321 less noticeable compared to conventional pachinko machines, making it easier for players who are accustomed to conventional pachinko machines to recognize that it is clearly different, resulting in a pachinko machine 1 that is highly appealing and strongly attracts the interest of players.

[0304] In addition, the door frame 3 is formed so that the lower plate 322 wraps around the rear side of the performance operation unit 400 with respect to the lower plate opening 326d that opens to the left side of the performance operation unit 400 on the front side of the plate unit 320, so that the volume of the lower plate 322 can be made large relative to the size of the lower plate opening 326d, and the number of game balls stored in the lower plate 322 can be sufficiently secured. In addition, since the rear part of the lower plate 322 wraps around the rear side of the performance operation unit 400, when a player puts his / her left hand inside the lower plate 322 or puts his / her fingers on the lower plate opening 326d, it is difficult for the fingertips to touch the rear wall of the lower plate 322, so that it is possible to prevent the player from feeling uncomfortable, suppress a decrease in interest in the game, and also to make the player recognize by touch that the volume of the lower plate 322 is large compared to the size of the lower plate opening 326d.

[0305] Furthermore, the door frame 3 has a lower tray ball supply port 323c, through which game balls from the upper tray 321 are released into the lower tray 322, and a lower tray ball removal hole 322a, through which game balls on the lower tray 322 are removed into a coin box or the like below the tray unit 320, arranged in a straight line from front to back, and are located on the right outer side of the lower tray opening 326d when viewed from the front (to the right of the left end of the frame unit 415 of the performance operation unit 400). In other words, since the lower tray ball supply port 323c and the lower tray ball removal hole 322a are positioned behind the performance operation unit 400, the performance operation unit mounting portion 326a (the outer right side of the lower tray opening 326d) on the tray unit cover 326, the front end side of the lower tray cover 340, etc., the lower tray ball supply port 323c and the lower tray ball removal hole 322a are not visible from the player's side, which makes the appearance of the tray unit 320 (pachinko machine 1) neat and tidy, and improves the appearance of the pachinko machine 1.

[0306] In addition, the door frame 3 has the lower tray ball ejection hole 322a located below (directly in front of) the lower tray ball supply port 323c in the lower tray 322, so that when the lower tray ball ejection hole 322a is opened, the game balls released from the upper tray 321, etc. to the lower tray 322 will be ejected from the lower tray ball ejection hole 322a to the dollar box, etc. below as soon as they enter the lower tray 322. At this time, the lower tray ball supply port 323c and the lower tray ball ejection hole 322a are not visible from the player's side, so the flow of game balls ejected from the upper tray 321, etc. through the lower tray 322 to the dollar box cannot be seen. This gives the player the illusion that the game balls in the upper tray 321 or the game balls paid out from the payout device 830 when the upper tray 321 is full are being discharged directly into the coin box, making it less likely that the player will feel annoyed by the game balls passing through the lower tray 322, allowing the player to concentrate on the game (the operation of shooting the game balls in and the presentation images, etc.) and preventing a decline in interest.

[0307] In addition, the door frame 3 has a lower tray ball removal hole 322a located on the lower tray 322, toward the front and left of the lower tray ball supply port 323c, and the raised wall portion of the lower tray 322 to the right of the lower tray ball removal hole 322a is curved diagonally toward the lower tray ball removal hole 322a, so that game balls supplied to the lower tray 322 from the lower tray ball supply port 323c can be directly guided to the lower tray ball removal hole 322a, or indirectly guided to the lower tray ball removal hole 322a by being reflected off the right wall portion. As a result, when the lower tray ball removal hole 322a remains open, the game balls supplied to the lower tray 322 from the lower tray ball supply port 323c can be discharged downward from the lower tray ball removal hole 322a without entering the area to the left of the lower tray ball removal hole 322a in the lower tray 322 (lower tray first area A1).This means that the game balls can be discharged below the lower tray 322 (to the dollar box) without the player being able to see the game balls circulating within the lower tray 322, thereby achieving the same effect as described above.

[0308] In addition, the door frame 3 has a lower dish opening 326d of the dish unit cover 326, through which the lower dish 322 faces forward, between the performance operation unit mounting portion 326a (performance operation unit 400) and the lower speaker port 326e, so that even if the player places his / her hand on the lower dish opening 326d or puts his / her hand into the lower dish 322, the front of the lower speaker port 326e is not blocked by the player's hand, so that the sound from the lower speaker 921 in the board unit 900 of the main body frame 4 can be output forward well, and the player can enjoy the sound from this pachinko machine 1. In addition, when the player puts his / her hand into or approaches the lower dish 322, the player can feel the vibrations caused by the deep bass sound from the lower speaker 921 output forward from the lower speaker port 326e tactilely, which entertains the player and suppresses a decline in interest.

[0309] In addition, the door frame 3 is equipped with a door frame right side unit 550 that is plate-shaped and protrudes significantly forward from the right side of the through opening 111. Therefore, when this pachinko machine 1 is installed in an island facility in an arcade, the door frame right side unit 550 can act as a partition between it and the adjacent pachinko machine on the right side, giving players playing with this pachinko machine 1 the illusion that they are playing in a private room, allowing them to play in a relaxed atmosphere without having to worry about other players around them.

[0310] Furthermore, the door frame 3 can be decorated with illuminating light on the front end and both left and right sides of the door frame right side unit 550, which is plate-shaped and protrudes significantly forward. Therefore, even if a person is not positioned in front of the pachinko machine 1 in a gaming hall where the pachinko machines 1 are installed side by side, the presence of the pachinko machine 1 can be made known from a distance, such as from the side along the island equipment, making the pachinko machine 1 highly appealing to players.

[0311] In addition, the door frame 3 is provided with a top middle decorative member 576 that protrudes forward in the center in the left-right direction in the door frame top unit 570 above the through-hole 111, and the front sides of the top middle decorative member 576 on both sides are formed in a shape that is recessed so as to be carved out backward (a concave curved shape so that the front sides of the top middle decorative member 576 on both sides of the door frame top unit 570 are positioned further backward than the straight line connecting the front ends of both the left and right ends of the door frame top unit 570 and the front ends of both the left and right ends of the top middle decorative member 576). As a result, only the top middle decorative member 576 of the door frame top unit 570 appears to protrude greatly forward, so that the top middle decorative member 576 can be made to stand out and be emphasized to the player, and the top middle decorative member 576 can be strongly drawn attention to it.

[0312] In the conventional pachinko machine, a pair of upper speakers spaced apart from each other are provided on the upper part of the door frame, and the two upper speakers stand out. In contrast, the door frame 3 of this embodiment is provided with a pair of upper speakers 573 whose front faces are protected by speaker covers 575 made of punching metal on both left and right ends in the door frame top unit 570 attached to the upper side of the through hole 111, and is provided with a top left decorative lens member 579 and a top right decorative lens member 580 that extend from both left and right sides of the central top middle decorative member 576 through the front of the speaker cover 575 to both left and right ends, so that the entire front of the top left decorative lens member 579 and the top right decorative lens member 580 can be illuminated and decorated. As a result, the entire upper front surface of the door frame 3 can be decorated, making the pair of upper speakers 573 less noticeable at the top of the door frame 3 and allowing the player to recognize at a glance that the decoration is clearly different from that of conventional pachinko machines, making the pachinko machine 1 more appealing to players and enabling the player to enjoy high quality stereo sound from the pair of upper speakers 573.

[0313] In this way, in the door frame 3 of this embodiment, the performance operation unit 400 attached to the tray unit 320 and the top middle decorative member 576 of the door frame top unit 570 each protrude significantly forward in the center in the left-right direction below and above the through opening 111, allowing the player to see a unified decoration from top to bottom with a prominent imaginary line passing through the center in the left-right direction, and the sophisticated decoration makes the machine stand out more than other pachinko machines, making it a pachinko machine 1 with high appeal.

[0314] In addition, the door frame 3 has the top middle decorative member 576 of the door frame top unit 570 and the performance operation unit 400, which are arranged vertically in the center in the left-right direction, protruding forward. Therefore, when the top middle decorative member 576 and the performance operation unit 400 are illuminated, the player can see an illuminated line extending vertically in the center in the left-right direction on the front of the door frame 3, and the player's gaze can be guided to the operation buttons 410, etc. of the performance operation unit 400, which are arranged in the center in the left-right direction.

[0315] [5. Overall composition of the game board] Next, the overall structure of the game board 5 of the pachinko machine 1 will be described in detail with reference to Figs. 60 to 66. Fig. 60 is a front view of the game board. Fig. 61 is an exploded perspective view of the game board disassembled into its main components as seen from the front, and Fig. 62 is an exploded perspective view of the game board disassembled into its main components as seen from the back.

Fig. 66 is an explanatory diagram showing the function display unit portion enlarged from the front when the game board is attached to the pachinko machine.

[0316] The game board 5 has a game area 5a into which game balls are shot by a player operating the handle 302 of the handle unit 300. The game board 5 also includes a front component 1000 that defines the outer periphery of the game area 5a and has a generally rectangular shape in front view, a plate-shaped game panel 1100 that is attached to the rear side of the front component 1000 and defines the rear end of the game area 5a, a board holder 1200 that is attached to the rear lower part of the game panel 1100, and a main control unit 1300 that is attached to the rear surface of the board holder 1200 and has a main control board 1310 that controls the game content performed by shooting game balls into the game area 5a. A plurality of obstacle nails that come into contact with the game balls are planted in a predetermined gauge arrangement in a portion of the front surface of the game panel 1100 that is within the game area 5a (not shown).

[0317] The game board 5 further includes a function display unit 1400 that displays the game status based on a control signal from the main control board 1310 and is attached to the lower left corner of the front component 1000 so as to be visible to the player, a peripheral control unit 1500 attached to the rear side of the game panel 1100, a game board side performance display device 1600 that is located in the center of the game area 5a when viewed from the front and can display a predetermined performance image, a front unit 2000 attached to the front of the game panel 1100, and a rear unit 3000 attached to the rear side of the game panel 1100. The game board side performance display device 1600 is attached to the rear side of the rear unit 3000, and the peripheral control unit 1500 is attached to the rear side of the game board side performance display device 1600.

[0318] The game panel 1100 comprises a transparent, flat panel plate 1110 whose outer periphery is formed slightly larger than the inner periphery of the frame-shaped front component 1000, and a frame-shaped panel holder 1120 which holds the outer periphery of the panel plate 1110, is attached to the rear side of the front component 1000, and has a rear unit 3000 attached to its rear surface.

[0319] The front unit 2000 is equipped with a plurality of general winning openings 2001 that are always open so as to be able to accept game balls dropped into the game area 5a, a first starting opening 2002 that is always open so as to be able to accept game balls at a different position in the game area 5a from the plurality of general winning openings 2001, a gate unit 2003 that is attached to a predetermined position in the game area 5a and detects the passage of the game ball, a second starting opening 2004 that is able to accept the game ball depending on the result of a normal lottery that is drawn when the game ball passes through the gate unit 2003, and a special winning opening 2005 that is able to accept the game ball either depending on the result of a first special lottery or the result of a second special lottery that is drawn when a game ball is accepted into the first starting opening 2002 or the second starting opening 2004.

[0320] The front unit 2000 also includes a start port unit 2100 which is attached directly above the out port 1126 in the left-right center of the game area 5a and has a first start port 2002 and a large prize port 2005, a lower side unit 2200 which is attached along the inner rail 1002 to the left of the start port unit 2100 when viewed from the front and has a plurality of general prize ports 2001, an upper side unit 2300 which is attached to the upper left end of the lower side unit 2200 when viewed from the front, and a frame-shaped center device 2500 which is attached approximately in the center of the game area 5a and has a gate portion 2003 and a second start port 2004.

[0321] The rear unit 3000 comprises a rear box 3010 which is attached to the rear surface of the panel holder 1120, is box-shaped with an open front and has a square opening 3010a in the rear wall, and a locking mechanism 3020 which is attached to the rear surface of the rear box 3010 and allows the game board side performance display device 1600 to be detachably attached.

[0322] Furthermore, the rear unit 3000 is equipped with a rear left middle decorative unit 3050 which is attached at the front end of the rear box 3010, from the center in the vertical direction toward the top on the left side when viewed from the front, a rear bottom rear movable performance unit 3100 which is attached below the opening 3010a inside the rear box 3010 and near the rear wall of the rear box 3010, a rear top left movable performance unit 3200 which is attached above the opening 3010a inside the rear box 3010 and on the left side when viewed from the front, a rear left movable performance unit 3300 which is attached to the left side of the opening 3010a inside the rear box 3010 when viewed from the front, a rear top middle movable performance unit 3400 which is attached above the opening 3010a inside the rear box 3010 from the center in the horizontal direction to the right edge when viewed from the front, and a rear bottom front movable performance unit 3500 which is attached below the opening 3010a inside the rear box 3010 in front of the rear bottom rear movable performance unit 3100.

[0323] [5-1. Front components] Next, the front component 1000 will be described mainly with reference to Figures 64 and 65. The front component 1000 has an outer shape of a substantially square in front view, an inner shape of a substantially circular shape penetrating in the front-rear direction, and the inner circumference of the inner shape defines the outer circumference of the play area 5a. The front component 1000 includes an outer rail 1001 that extends in an arc shape from the lower end on the left side of the center in the front view to the upper right diagonal direction in the clockwise circumferential direction, passing the upper end of the center in the front-rear direction to the upper right diagonal direction, an inner rail 1002 that is disposed inside the front component 1000 along the outer rail 1001 and extends in an arc shape from the lower center in the front-rear direction to the upper left diagonal direction in the front view, and an out guide portion 1003 that is formed at the lowest position of the play area 5a on the right side of the lower end of the inner rail 1002 in the front view and is inclined so as to become lower toward the rear.

[0324] In addition, the front component 1000 is equipped with a lower right rail 1004 that slopes linearly from the right end of the out guiding section 1003 when viewed from the front to near the right edge of the front component 1000, with the right end being slightly higher, a right rail 1005 that extends from the right end of the lower right rail 1004 along the right edge of the front component 1000 to the underside of the upper end of the outer rail 1001, with the upper part curved inward of the front component 1000, and a collision stop section 1006 that connects the upper end of the right rail 1005 to the upper end of the outer rail 1001 and is brought into contact with a game ball rolling along the outer rail 1001.

[0325] In addition, the front component 1000 is rotatably supported on the upper end of the inner rail 1002, and is equipped with a backflow prevention member 1007 which is rotatable only between a closed position in which it extends upward from the upper end of the inner rail 1002 to close the gap with the outer rail 1001, and an open position in which it rotates clockwise when viewed from the front to open the gap with the outer rail 1001, and which is biased by a spring (not shown) to return to the closed position.

[0326] Furthermore, the front component 1000 is provided with security recesses 1008 recessed rearward from the front end at the outside of the vicinity of the portions extending substantially vertically from the lower ends of the outer rail 1001 and the inner rail 1002, the underside of the out guide portion 1003 and the lower right rail 1004, and the outside of the right rail 1005. When the game board 5 is attached to the main body frame 4 and the door frame 3 is closed against the main body frame 4, the security recesses 1008 are inserted into the rear projections 202 of the security cover 200 on the door frame 3, which project rearward. As a result, the area between the security cover 200 and the game board 5 (front component 1000) is complexly bent by the rear protrusion 202 of the security cover 200 and the security recess 1008 of the front component 1000, so that even if an attempt is made to insert an illegal tool such as a piano wire into the game area 5a between the security cover 200 and the front component 1000 from below the front of the game board 5, the attempt will be blocked by the rear protrusion 202 and the security recess 1008, preventing the illegal tool from entering the game area 5a.

[0327] In addition, the front component 1000 is provided with a plurality of positioning protrusions 1009 protruding rearward from the rear end of the inner rail 1002. These positioning protrusions 1009 can be inserted into inner rail fixing holes 1116 formed in a panel plate 1110 of the game panel 1100 to position and fix the inner rail 1002 to the front surface of the panel plate 1110.

[0328] Furthermore, the front component 1000 has a plurality of mounting bosses 1010 protruding rearward from the rear surface. The mounting bosses 1010 are inserted into mounting holes 1128 of a panel holder 1120 in the gaming panel 1100, thereby enabling positioning between the panel holder 1120 (gaming panel 1100) and the mounting bosses 1010.

[0329] The component 1000 also has a cutout 1011 cut upward from the bottom end at the bottom left corner when viewed from the front. This cutout 1011 coincides with a cutout 1127 of the panel holder 1120 in the game panel 1100, and when the game board 5 is attached to the main body frame 4, the front end openings of the normal guide path 861 and the full ball guide path 862 of the lower full ball path unit 860 penetrate these cutouts 1011 and 1127 and face forward.

[0330] [5-2. Game Panel] Next, the gaming panel 1100 will be described mainly with reference to Figures 61, 62, 64, 65, etc. The gaming panel 1100 includes a flat panel plate 1110 whose outer periphery is formed slightly larger than the inner periphery of the frame-shaped front component member 1000 and which is made of transparent synthetic resin, and a frame-shaped panel holder 1120 which holds the outer periphery of the panel plate 1110 and is attached to the rear side of the front component member 1000 and has a rear unit 3000 attached to its rear surface.

[0331] The panel board 1110 of the game panel 1100 is formed of a synthetic resin board such as acrylic resin, polycarbonate resin, polyarylate resin, or methacrylic resin, or an inorganic board such as glass or metal. The thickness of this panel board 1110 is thinner than the panel holder 1120 (game panel 1150), and is set to the minimum necessary thickness (8 to 10 mm) that can sufficiently hold obstacle nails planted on the front surface or the front unit 2000 attached. In this example, the panel board 1110 is formed of a transparent synthetic resin board.

[0332] The panel board 1110 has an out recess 1111 recessed upward from the lower end at the lowest position in the play area 5a. The panel board 1110 also has a plurality of openings 1112 penetrating from front to back and for mounting the front unit 2000.

[0333] The panel plate 1110 also has a plurality of fitting holes 1113, which are round holes arranged near the outer periphery and penetrate in the front-rear direction, and a long hole 1114 arranged near the outer periphery at the lower left, which penetrates in the front-rear direction and extends in the up-down direction. These fitting holes 1113 and long holes 1114 are arranged outside the play area 5a and are used to position the panel plate 1110 with respect to the panel holder 1120. The panel plate 1110 also has step-shaped engagement steps 1115, which are recessed at the front side, at both ends of the upper side and both ends of the lower side. These engagement steps 1115 are cut out to approximately half the thickness of the panel plate 1110, and are arranged outside the play area 5a, similar to the fitting holes 1113 and long holes 1114, to engage and fix the panel plate 1110 to the panel holder 1120.

[0334] The panel plate 1110 is also provided with a plurality of inner rail fixing holes 1116 at predetermined positions. By fitting and fixing positioning protrusions 1009 protruding from the rear side of the inner rail 1002 into these inner rail fixing holes 1116, the inner rail 1002 can be fixed in a predetermined position.

[0335] The panel holder 1120 of the game panel 1100 has an outer shape that is approximately rectangular and large enough to include the panel board 1110, and is thicker than the panel board 1110 (approximately 20 mm in this example). The panel holder 1120 is made of synthetic resin (for example, thermoplastic synthetic resin). The panel holder 1120 has a holding step 1121 that detachably holds the panel board 1110 and is recessed from the front side to the rear side, and a through hole 1122 that penetrates in the front-rear direction inside the holding step 1121 and has a size approximately equal to the play area 5a.

[0336] The holding step 1121 of the panel holder 1120 has a depth from the front surface that is approximately the same as the thickness of the panel plate 1110, so that the front surface of the panel plate 1110 held in the holding step 1121 is approximately flush with the front surface of the panel holder 1120. The holding step 1121 is also sized so that its front inner peripheral surface forms a predetermined amount of clearance with respect to the outer peripheral surface of the panel plate 1110. This clearance makes it possible to absorb any expansion and contraction of the panel plate 1110 relative to the panel plate 1110 caused by temperature changes or changes over time.

[0337] The panel holder 1120 is disposed at a position corresponding to the fitting holes 1113 and long holes 1114 formed in the panel plate 1110 held by the holding step 1121, extends forward from the front surface of the holding step 1121, and has a plurality of protruding pins 1123 that can fit into and pass through the fitting holes 1113 and long holes 1114 of the panel plate 1110. By fitting and inserting these protruding pins 1123 into and through the fitting holes 1113 and long holes 1114 of the panel plate 1110, the panel holder 1120 and the panel plate 1110 can be positioned relative to each other.

[0338] Furthermore, the panel holder 1120 is provided with an engagement claw 1124 and an engagement piece 1125 that engage with the engagement step 1115 at a position corresponding to the engagement step 1115 of the panel plate 1110. In detail, the engagement claw 1124 is disposed on the upper part of the holding step 1121 of the panel holder 1120, corresponds to the upper engagement step 1115 of the panel plate 1110, protrudes forward from the front surface of the holding step 1121, and elastically engages with the engagement step 1115. The engagement claw 1124 is sized so that its tip does not protrude from the front surface of the panel holder 1120.

[0339] The engagement piece 1125 of the panel holder 1120 is disposed under the holding step 1121 of the panel holder 1120, and corresponds to the lower engagement step 1115 of the panel plate 1110. This engagement piece 1125 extends a predetermined distance toward the upper side (toward the center) along the front surface of the panel holder 1120, with a gap of a size large enough to allow the engagement step 1115 of the panel plate 1110 to be inserted between the engagement piece 1125 and the front surface of the holding step 1121. The panel plate 1110 is detachably held by the panel holder 1120 by engaging the engagement step 1115 of the panel plate 1110 with the engagement claw 1124 and engagement piece 1125.

[0340] The panel holder 1120 also has an outlet 1126 that penetrates from front to back at the lowest position in the play area 5a. The lower rear side of the panel holder 1120 is recessed forward to the bottom end with the same width as the outlet 1126.

[0341] Furthermore, the panel holder 1120 has a cutout 1127 cut upward from the lower end at the lower left corner when viewed from the front. This cutout 1127 coincides with the cutout 1011 of the previous component 1000, and when the game board 5 is attached to the main body frame 4, the front end openings of the normal guide path 861 and the full ball guide path 862 of the lower full ball path unit 860 penetrate these cutouts 1011 and 1127 and face forward.

[0342] The panel holder 1120 also has a plurality of mounting holes 1128 penetrating from front to back at positions corresponding to the plurality of mounting bosses 1010 in the front component 1000. By inserting the mounting bosses 1010 of the front component 1000 into these mounting holes 1128, the panel holder 1120 can be attached to the rear side of the front component 1000, and the panel holder 1120 (game panel 1100) can be positioned between the front component 1000 and the panel holder 1120.

[0343] The panel holder 1120 also has a square insertion hole 1129 penetrating in the front-rear direction above the cutout portion 1127. The rear end of the function display unit 1400 is inserted into this insertion hole 1129.

[0344] When the game panel 1100 is attached to the rear side of the front component 1000, the outlet 1126 of the panel holder 1120 opens to the rear side of the out guide part 1003 of the front component 1000. As a result, game balls that have flowed down to the bottom end of the game area 5a are guided to the rear outlet 1126 by the out guide part 1003, and are discharged to the rear side of the game panel 1100 through the outlet 1126.

[0347] In addition, the game panel 1150 is provided with a cutout 1152 which penetrates horizontally in the front-to-back direction on the left side of the lower end when viewed from the front and which is open downward and has the same shape as the cutout 1011 of the previous component 1000, and a square insertion hole 1153 which penetrates in the vertical direction above the cutout 1152 and through which the rear end of the function display unit 1400 is inserted.

[0348] The game panel 1150 also has a plurality of inner rail fixing holes 1154 penetrating from the front to the rear, into which the positioning protrusions 1009 can be fitted, at positions corresponding to the positioning protrusions 1009 protruding rearward from the inner rail 1002 of the front component 1000. The game panel 1150 also has a plurality of mounting holes 1155 penetrating from the front to the rear, at positions corresponding to the mounting bosses 1010 of the front component 1000. By inserting the mounting bosses 1010 of the front component 1000 into these mounting holes 1155, the game panel 1150 can be attached to the rear side of the front component 1000, and the game panel 1150 can be positioned between the front component 1000 and the front component 1000.

[0349] Furthermore, although not shown, the game panel 1150 is provided with a number of openings extending from front to back for mounting the front unit 2000, similar to the openings 1112 of the panel board 1110 in the game panel 1100 described above.

[0350] When the game panel 1150 is attached to the rear side of the front component 1000, the outlet 1151 opens to the rear side of the out guide part 1003 of the front component 1000. As a result, game balls that flow down to the bottom end of the game area 5a are guided to the rear outlet 1151 by the out guide part 1003, and are discharged to the rear side of the game panel 1150 through the outlet 1151.
