[0008] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Figures 1 to 11 show a first embodiment in which the present invention is applied to a pachinko machine. In Figures 1 and 2, a gaming machine main body 1 has a rectangular outer frame 2 and an inner frame 4 pivotally attached to the front of the outer frame 2 by a hinge 3 on one of the left and right sides, for example the left side, so as to be freely opened and closed.

[0009] On the front side of the inner frame 4, a game board mounting frame 6 for mounting a game board 5 is arranged on its upper side, and a launching means 7, a lower speaker 10, etc. are arranged on the lower side, and a front door 8 covering the front sides of these is pivotally attached so as to be freely opened and closed by a hinge 9 on the same side as the hinge 3.

[0010] 2, the launching means 7 includes a support plate 11 made of sheet metal, a launching rail 12 attached to the front of the support plate 11, a ball holding section 13 attached to the front of the support plate 11 and holding the game balls to be launched on the launching rail 12, a striking hammer 15 supported on the front of the support plate 11 so as to be swingable around a drive shaft 14 in the front-rear direction, and a launching drive means 16 such as a rotary solenoid attached to the back side of the support plate 11 and driving the striking hammer 15 in the striking direction via the drive shaft 14. When the launch handle 17 on the front door 8 side is operated, the launching drive means 16 continuously drives the striking hammer 15 in the striking direction (clockwise) according to the amount of operation. As a result, the game balls supplied one by one on the launching rail 12 are launched along the launching rail 12 toward the play area 5a of the game board 5.

[0011] The game board 5 is attached to the game board mounting frame 6, for example from the front side, and is fixed so as to be freely attached and detached by one or more fixing devices 18. A guide rail 21 for guiding the game ball launched by the launching means 7 is attached in a ring shape to the front side, and various game components such as a central display unit 22, a normal pattern starting means 23, a special pattern starting means 24, a big prize means 25, a normal prize means 26, etc. are arranged in the game area 5a inside the guide rail 21.

[0012] The central display unit 22 is provided with an image display means 27 such as a liquid crystal type, as well as a normal symbol display means 28, a special symbol display means 29, a normal reserved number display means 30, etc. The image display means 27 constitutes a performance symbol display means 31, a special reserved number display means 32, etc.

[0013] The normal pattern display means 28 is composed of two light-emitting elements (e.g., LEDs) corresponding to two types of normal patterns, for example, "○" and "X". When the normal pattern starting means 23, consisting of a passing gate or the like, detects a gaming ball, the two light-emitting elements flash alternately for a predetermined period of time. When the winning judgment random number value contained in the normal random number information acquired when the normal pattern starting means 23 detects the gaming ball matches a predetermined winning judgment value, the light-emitting element on the "○" side corresponding to the winning state lights up, and otherwise the light-emitting element on the "X" side corresponding to the losing state lights up, and the flashing ends.

[0014] The normal random number information acquired when the normal symbol starting means 23 detects a game ball is reserved and stored up to a predetermined upper limit of reserved number, for example, 4 pieces, and each time a normal symbol can be changed, one piece is consumed and the normal symbol is changed. The number of stored normal random number information (hereinafter, normal reserved number) is notified to the player by, for example, the number of light-emitting elements by the normal reserved number display means 30, which has the same number of light-emitting elements as the upper limit of reserved number.

[0015] The special symbol start means 24 is for starting the symbol variation by the special symbol display means 29, and is provided with, for example, two upper and lower start winning means 24a, 24b, and is disposed below the central display unit 22. The upper start winning means 24a is a non-opening / closing type winning means that does not have an opening / closing means or the like. The lower start winning means 24b is an opening / closing type winning means that can be switched by the opening / closing means 33 between a closed state in which the game ball cannot enter (or is difficult to enter) and an open state in which the game ball can enter (or is easier to enter than in the closed state), and is opened from the closed state to the open state for a predetermined time when the stopped symbol after the variation of the normal symbol display means 28 becomes a winning state and a normal profit state occurs.

[0016] The special pattern display means 29 is composed of a display means such as a 7-segment type capable of variably displaying one or more special patterns, for example one special pattern, and variably displays the special pattern for a predetermined period of time on the condition that the special pattern starting means 24 detects a game ball, i.e., the game ball enters either of the two upper and lower starting winning means 24a, 24b, and if the jackpot determination random number value contained in the special random number information obtained when the ball enters the starting winning means 24a, 24b matches a predetermined jackpot determination value, it stops in a predetermined jackpot mode (specific mode), and in other cases it stops in, for example, a miss mode.

[0017] The special random number information acquired when the special symbol starting means 24 detects a game ball is stored up to a predetermined upper limit of reserved numbers, for example, four, and each time the special symbol display means 29 becomes capable of changing the pattern, one is consumed to change the special symbol. The number of stored special random number information (hereinafter, special reserved number) is notified to the player by the special reserved number display means 32, for example, by the number of reserved display images X displayed.

[0018] The performance pattern display means 31 displays the performance patterns in a changing manner in parallel with the changing display of the special patterns by the special pattern display means 29, and is configured to be able to change and display one or more performance patterns, for example three performance patterns in the left and right direction, on the display screen 27a of the image display means 27 together with various performance images, and when the special pattern start means 24 detects a game ball, that is, when the game ball wins in either of the two upper and lower start winning means 24a, 24b, it starts changing the performance patterns according to one of a plurality of types of change patterns approximately simultaneously with the start of the special pattern change, and stops the performance patterns in a predetermined order such as left, right, center, etc., so that they finally stop approximately simultaneously with the stop of the special pattern change.

[0019] The big winning means 25 is an opening / closing type winning means equipped with an opening / closing plate 25a that can be switched between an open state where the game ball can enter and a closed state where the game ball cannot enter, and when the special pattern after the change in the special pattern display means 29 becomes a big win state and a special profit state occurs, the opening / closing plate 25a opens forward according to a predetermined opening pattern, allowing the game ball that falls onto it to enter the winning state.

[0020] The front door 8 is provided with a door base 35 made of, for example, resin, in which a window hole 34 corresponding to the front side of the game area 5a is formed.

[0042] Next, a configuration regarding heat dissipation measures for the LED driver 75 will be described. As shown in Fig. 8, the LED driver (heat-generating component) 75 has a rectangular conductor pad (conductor portion) 151 made of copper foil or other conductor on its back surface, and this conductor pad 151 is fixed to the board body 111 by bonding (soldering) to the solid ground pattern (copper foil portion) 136 on the second wiring layer (first surface) 141b side. In this embodiment, as shown in Figs. 8 and 9(a), the board thickness T of the board body 111 is 1 mm, the vertical dimension X of the conductor pad 151 is 5.3 mm, the horizontal dimension Y is 5.3 mm, and the area S is 28.09 mm. 2In addition, in the first wiring layer 141a on the opposite side, a solid ground pattern 137 is arranged at least in a region corresponding to a conductor pad (conductor portion) 151 of the LED driver 75 (here, a region including a region corresponding to the LED driver 75, which is a heat-generating component) (FIG. 5(a)).

[0043] Furthermore, in the substrate body 111, a predetermined number of through holes 140a are arranged in a matrix in an area corresponding to the conductor pad 151. The through holes 140a have copper foil applied to their inner surfaces, and the through holes 140a electrically connect the solid ground pattern 136 on the second wiring layer 141b side to the solid ground pattern 137 on the first wiring layer 141a side. In this embodiment, as shown in Fig. 8 and Fig. 9(a), nine through holes 140a having a diameter φ=0.6 mm are arranged in a 3 × 3 matrix at equal intervals vertically and horizontally within the square area of ​​the conductor pad 151, and the hole interval Ls of the through holes 140a is larger than the diameter φ of the through holes 140a (here, 1.2 mm).

[0044] By providing such a through hole 140a in the area corresponding to the conductor pad 151 of the LED driver 75, which is a heat-generating component, heat can be dissipated from the inner surface of the through hole 140a, and heat from the LED driver 75 located on the rear side, which is close in distance (L1) to the opposing surface (door base 35), can be dissipated more efficiently by escaping to the front side, which has a larger distance (L2) to the opposing surface (upper decorative cover 49).

[0045] In addition, the third LED substrate 43 of this embodiment is provided with three types of through holes: a signal conduction via (through hole) for conducting a signal wiring path between different wiring layers, a power supply conduction via (through hole) for conducting a power supply wiring path between different wiring layers, and a heat dissipation through hole mainly for the purpose of heat dissipation. The above-mentioned through hole 140a is a heat dissipation through hole that also serves as a power supply conduction via. In the third LED substrate 43 of this embodiment, as shown in FIG. 7, the relationship between the diameter φ of the heat dissipation through hole such as the through hole 140a, the diameter φ1 of the signal conduction via such as the via 140b, and the diameter φ2 of the power supply conduction via such as the via 140c is φ1<φ≒φ2.

[0046] Here, when the through-hole 140a is provided within the region of the conductor pad 151, the adhesion area of ​​the LED driver 75 to the substrate body 111 is reduced by the hole area of ​​the through-hole 140a, and the adhesive strength is reduced accordingly. On the other hand, since the copper foil is formed on the inner surface of the through-hole 140a, the heat dissipation area is increased by the surface integral of the inner surface, and the amount of heat dissipation is increased. Therefore, the larger the diameter φ of the through-hole 140a, the higher the heat dissipation effect, but on the other hand, the adhesive strength of the LED driver 75 is reduced.

[0047] Therefore, in this embodiment, the thickness T (mm) of the substrate body 111 and the diameter φ and number n of the through holes 140a within the area of ​​the conductor pad 151 are set so that the copper foil increase rate Ri (%), which is the ratio of the surface area S1 of the through hole 140a to the area S of the conductor pad 151, is greater than the porosity Rs (%), which is the ratio of the hole area S2 of the through hole 140a to the area S of the conductor pad 151.

[0048] Specifically, as shown in FIG. 9(b), the surface area S1 (mm 2 )=φπTn=16.956, hole area S2 of through hole 140a (mm 2 )=(φ / 2) 2πn = 2.543, the porosity Rs(%) = (S2 / S)×100 = 9.05, the copper foil increase rate (%) = Ri(%) = (S1 / S)×100 = 60.36, and Rs < Ri.

[0049] This can be rephrased as saying that the rate of increase in the heat dissipation effect due to the formation of the through-hole 140a is greater than the rate of decrease in the adhesive strength due to the formation of the through-hole 140a. That is, by providing the through-hole 140a, the adhesive strength of the LED driver 75 is somewhat sacrificed, but the heat dissipation effect can be increased even more. In this embodiment, as described above, since the hole pitch Ls of the through-hole 140a is larger than the diameter φ of the through-hole 140a (Fig. 8(b)), it is possible to ensure a certain adhesive strength while providing the through-hole 140a.

[0050] Here, the fact that Rs < Ri means that S1 > S2. Therefore, as shown in Fig. 9(b), the net increase in the copper foil area Sni(mm 2 ) = S1 - S2 = 14.413, that is, Sni > 0.

[0051] Also, in this embodiment, as shown in Fig. 9(b), the total copper foil area Sa(mm 2 ) = S + Sni = 42.503, and the copper foil net increase rate Rni(%) = (Sa / S)×100 = 151.31.

[0052] Next, a burr countermeasure for the third LED substrate 43 will be described. As shown in FIG. 5, one or more recesses 161, here four recesses, are formed on the outer periphery of the third LED substrate 43. As shown in FIG. 10, a burr 162 remains in the recess 161, which is formed by separating the substrate body 111 from the throw-away substrate 163 (FIG. 11). The depth of the recess 161 (hereinafter referred to as recess depth D) is greater than the protruding length of the burr 162 (hereinafter referred to as burr length L). In this way, by making the burr 162 remain in the recess 161 and making D>L, the burr 162 does not protrude outward from the outer edge of the substrate body 111 even without removing the burr, and it is possible to omit the burr removing process and simplify the manufacturing process.

[0053] 11 shows a state before the substrate body 111 of the third LED substrate 43 is separated from the sacrificial substrate (adjacent portion) 163. A slit 164 of a substantially constant width (hereinafter referred to as slit width W) is formed between the substrate body 111 and the sacrificial substrate 163. The slit 164 is composed of a bent slit portion 164a that forms the recess 161, and a general slit portion 164b that forms the outer shape of the substrate body 111 excluding the recess 161.

[0054] The bent slit portion 164a is formed by a pair of bent portions 165, 165 that bend from the general slit portion 164b toward the substrate body 111, and an intermediate portion 166 formed between the pair of bent portions 165, 165. The intermediate portion 166 is formed in a substantially straight line and is missing at one or more locations (two locations in this case), and the missing portions serve as a connecting portion 167 that connects the substrate body 111 and the discarded substrate 163. Here, the length of the connecting portion 167 is equal to the slit width W. Also, since the burr 162 is the remaining portion after the connecting portion 167 is cut at approximately the center, the burr length L is approximately half the slit width W (L ≒ W / 2).

[0055] Also, the intermediate portion 166 is shifted toward the substrate body 111 by the recess depth D with respect to the general slit portion 164b, but in this embodiment, the relationship between the recess depth D and the slit width W is D=W. Therefore, in this embodiment, L≈W / 2=D / 2, and the recess depth D is approximately twice the burr length L.

[0056] The recess depth D and the burr length L become approximately the same (D ≒ L) when the recess depth D is 1 / 2 the slit width W (D = W / 2). Therefore, in order to make the recess depth D larger than the burr length L (D > L), it is sufficient to set the recess depth D to be larger than 1 / 2 the slit width W (D > W / 2).

[0057] Further, the bent portion 165 is bent at a predetermined angle from the general slit portion 164b toward the substrate body 111, and in this embodiment, the bent angle is smaller than 90 degrees (about 60 degrees here). That is, the recess 161 in this embodiment is formed so as to become wider from the inside (the substrate body 111 side) toward the outside.

[0058] In the third LED substrate 43 of this embodiment, both the first wiring layer 141a and the second wiring layer 141b have an area along the outer periphery where no copper foil is provided (hereinafter referred to as an outer periphery margin 171), but the width (the distance between the outer edge and the inner edge) of this outer periphery margin 171 differs between the recess 161 and other portions. That is, as shown in Fig. 10, the outer periphery margin 171a corresponding to the recess 161 is formed within a range of a substantially constant width WSa along the outer periphery (excluding the burrs 162), and the outer periphery margin 171b corresponding to the portion other than the recess 161 is formed within a range of a substantially constant width WSb along the outer periphery, with the relationship therebetween being WSa>WSb.

[0059] 10, the ground wiring path 138 is disposed inside the outer peripheral margin 171, and the signal and clock wiring paths 134, 135 are disposed further inside the ground wiring path 138. In this manner, in the third LED substrate 43 of this embodiment, the outer peripheral margin 171a where no copper foil is provided is formed within the range of WSa (first distance) from the outer peripheral edge in the portion of the recess 161, and the ground wiring path 138 is disposed inside the outer peripheral margin 171a, i.e., at a position at least WSa (first distance) away from the outer peripheral edge, and the signal wiring path 134 and the like are disposed further inside the outer peripheral margin 171a (i.e., at a position at least a second distance longer than WSa (first distance) from the outer peripheral edge). In addition, in the portion other than the recess 161, an outer margin 171b is formed in which no copper foil is provided within a range of WSb (less than a first distance) from the outer peripheral edge, and the ground wiring path 138 is arranged inside the margin 171b, i.e., at a position WSb shorter than WSa from the outer peripheral edge (a position less than the first distance), and the signal wiring path 134 etc. are arranged further inside that (i.e., a position less than a second distance from the outer peripheral edge).

[0060] With this configuration, even if a manufacturing error occurs and the recess 161 is formed displaced from its original position, the possibility of the ground wiring path 138, the signal wiring path 134, etc. being scraped off can be eliminated, and the wiring layer can be efficiently utilized. Also, resistance to vibration and impact when the connecting portion 167 is folded and broken in the manufacturing process can be improved. Note that, since the influence of vibration and impact when folding and breaking the connecting portion 167 is small at a position away from the recess 161, the peripheral margin 171 is made small to ensure the area of ​​the copper foil pattern.

[0061] As described above, the pachinko machine of this embodiment has a third LED board (board) 43 on which an LED driver (heat-generating component) 75 is mounted, and the LED driver 75 arranged on the first surface of the third LED board 43 has a conductor portion 151 provided on its back surface bonded to the copper foil portion on the first surface side, and nine (a predetermined number) through holes 140a with copper foil on the inner surface are provided in an area corresponding to the conductor portion 151 of the LED driver 75, and the plate thickness T of the third LED board 43, the diameter φ of the through hole 140a, and the predetermined number n are set so that the ratio Ri of the surface area S1 of the inner surface of the through hole 140a to the area S of the conductor portion 151 is larger than the ratio Rs of the hole area S2 of the through hole 140a to the area S of the conductor portion 151. This makes it possible to enhance heat dissipation while suppressing a decrease in the mounting strength of the LED driver (heat-generating component) 75.

[0062] In addition, nine (a predetermined number) through holes 140a are arranged in a matrix at equal intervals vertically and horizontally, and the interval Ls between the through holes 140a is set to be larger than the diameter φ of the through holes 140a. This makes it possible to ensure a certain level of adhesive strength even when the through holes 140a are provided.

[0063] Moreover, a solid ground pattern 137 is arranged on at least a region corresponding to the conductor portion 151 on the second surface opposite to the first surface of the third LED substrate 43. This makes it possible to efficiently dissipate heat conducted via the through holes 140a on the second surface side via the solid ground pattern 137.

[0064] Also, the LED driver (heat-generating member) 75 is arranged on the back surface (first surface) side facing the door base (first member) 35, and the LEDs 71 to 74 are arranged on the front surface (second surface) side facing the upper decorative cover (second member) 49, and the distance L2 between the upper decorative cover 49 and the third LED board 43 is set to be greater than the distance L1 between the door base 35 and the third LED board 43. This allows the heat from the LED driver 75 arranged on the back surface (first surface) side, which is close in distance (L1) to the opposing surface (door base 35), to escape to the front surface (second surface) side, which has a larger distance (L2) to the opposing surface (upper decorative cover 49), making it possible to dissipate heat more efficiently.

[0065] In addition, one or more recesses 161 are provided on the outer periphery of the third LED substrate 43, and burrs 162 created by cutting the connecting portions 167 remain in the recesses 161, and the depth D of the recesses 161 is made larger than the protruding length L of the burrs 162. Therefore, the burr removal process can be omitted, thereby making the manufacturing process more efficient.

[0066] Furthermore, no copper foil is provided within a first distance WSa from the outer periphery of the recess 161, the ground wiring path 138 is disposed at a position at least the first distance WSa away from the outer periphery of the recess 161, the signal wiring path 134 is disposed at a position at least a second distance away from the outer periphery of the recess 161 that is longer than the first distance WSa, and for the portion of the outer periphery of the third LED substrate 43 other than the recess 161, the ground wiring path 138 is disposed at a position less than the first distance WSa from the outer periphery, and the signal wiring path 134 is disposed at a position less than the second distance from the outer periphery. This makes it possible to eliminate the possibility that the ground wiring path 138, the signal wiring path 134, etc. will be scraped off even if a manufacturing error occurs and the recess 161 is formed deviated from its original position, and allows the wiring layer to be used efficiently.

[0067] Next, a second embodiment of the present invention will be described in detail with reference to the drawings. Figures 12 to 18 illustrate a second embodiment in which the present invention is applied to a pachinko machine. In Figure 12, a gaming machine main body 501 includes a rectangular outer frame 502 and a front frame 504 pivotally attached to the front of the outer frame 502 by a hinge 503 on one of the left and right sides, for example, the left side, so as to be freely opened and closed. In the front frame 504, a game board 505 and the like are arranged on the upper side, and a launching means 506 for launching game balls toward a game area 505a in front of the game board 505, a lower speaker SP1, and the like are arranged on the lower side, respectively, and a glass door 507 is arranged in front of the game board 505 and the like, and a front panel 508 is arranged in front of the launching means 506, the lower speaker SP1, and the like, and is pivotally supported by a hinge 509 on the same side as the hinge 503 so as to be freely opened and closed. The glass door 507 and the front panel 508 may be configured as a single door body so that they can be opened and closed as a unit.

[0068] The glass door 507 has a glass window 507a corresponding to the play area 505a at its approximate center, and various presentation means such as an upper speaker SP2 and an illumination device 510 are arranged around the glass window 507a. The illumination device 510 includes an LED board 511 on the front side of which an LED 511a is arranged, and a light-emitting lens section 512 arranged in front of the LED board 511. A synthetic resin glass frame cover 513 is provided on the front side of the glass door 507 to cover the upper speaker SP2 and the like from the front side, and at least a part of the glass frame cover 513 is the light-emitting lens section 512 having translucency. The light-emitting lens section 512 is subjected to a light diffusion treatment such as uneven processing in order to make the LED board 511 and the like inside difficult to see from the front side and to appropriately diffuse the light emitted from the LED 511a.

[0069] In front of the front panel 508, an upper tray 515 is arranged on the upper side for storing game balls dispensed from the dispensing means 514 (see FIG. 13) and supplying them to the launching means 506, and below the upper tray 515, a lower tray 516 for storing surplus balls when the upper tray 515 is full is arranged on the left end side, and a launch handle 517 for operating the launching means 506 is arranged on the right end side. Furthermore, various operating means such as a performance button 519 that can be pressed by a player are arranged on an upper tray cover 518 that covers the upper tray 515 from the front side. An illumination means may also be arranged on the upper tray cover 518.

[0070] A guide rail 520 that guides the game ball launched from the launching means 506 is attached in a ring shape to the front side of the game board 505, and various game components such as a center case 521, a normal pattern starting means 522, a special pattern starting means 523, a big prize means 524, and a normal prize means 525 are arranged in the game area 505a inside the guide rail 520.

[0071] The center case 521 is disposed, for example, approximately in the center of the game area 505a, and is provided with an approximately rectangular display window 527 corresponding to an image display means 526 such as a liquid crystal type, and on a decorative frame 528 surrounding the display window 527, various display means such as a normal pattern display means 531, a special pattern display means 532, a normal reserved number display means 533, a first special reserved number display means 534, as well as a stage 535, a movable performance means 536, etc. are provided.

[0072] The stage 535 is arranged in the left-right direction on the lower front side of the image display means 526, and allows the game balls that flow into the side of the center case 521, for example the warp entrance 535a on the left side, to roll freely and then drop to the front, for example from a central drop section in the center in the left-right direction or a side drop section on either side of that.

[0073] The movable performance means 536 includes a movable illumination device 540, a movable body guide means 541 for movably supporting the movable illumination device 540, and a drive means 542 for driving the movable illumination device 540. The movable illumination device (illumination device) 540 is formed in a horizontally long shape, and an arbitrary decoration (here, the characters "Kappa Densetsu", which is the title of the gaming machine) is formed three-dimensionally on the front side of the movable illumination device, and a predetermined part (here, the characters of "Kappa Densetsu") is illuminated in an arbitrary color by lighting an LED 573 arranged inside. The details of the movable illumination device 540 will be described later.

[0074] The movable body guide means 541 supports the movable illumination device 540 in a state in which it can move in a predetermined direction (here, the vertical direction) along the front side of the display screen 526a of the image display means 526, and includes a pair of guide rails 543 arranged in the vertical direction along both the left and right sides of the display screen 526a of the image display means 526, and both left and right ends of the movable illumination device 540 are supported so as to be vertically movable by each of the guide rails 543. The movable body guide means 541 allows the movable illumination device 540 to move in the vertical direction between an upper position on the upper side of the image display means 526 and a lower position on the front side of the image display means 526, and is normally held in the upper position which is the origin position.

[0075] The driving means 542 is constituted, for example, by a stepping motor and is arranged on the rear side of the decorative frame 528, and is capable of moving the movable illumination device 540 in the vertical direction according to a predetermined operating pattern via a belt or the like (not shown).

[0076] The normal pattern starting means 522 is used to start the pattern change by the normal pattern display means 531, and is composed of a passing gate through which the game ball can pass. It is arranged to the left of the center case 521, and is equipped with a game ball detection means (not shown) that can detect the passage of the game ball.

[0077] The normal pattern display means 531 is used to variably display normal patterns and is equipped with a plurality of light-emitting elements (e.g., LEDs) corresponding to a plurality of normal patterns (e.g., two types, "○" and "X"). Based on the detection of a gaming ball by the normal pattern starting means 522, the plurality of light-emitting elements blink to emit light in a predetermined sequence. If the winning determination random number value included in the normal random number information acquired when the normal pattern starting means 522 detects a gaming ball matches a predetermined winning determination value, the light-emitting element corresponding to the winning state, for example, on the "○" side, lights up, and otherwise the light-emitting element corresponding to the losing state, for example, on the "X" side, lights up and stops.

[0078] The normal random number information acquired when the normal symbol starting means 522 detects a game ball is reserved and stored up to a predetermined upper limit, for example, four pieces, and is consumed in sequence each time the normal symbol display means 531 starts changing the pattern. The number of stored normal random number information (normal reserved number) is notified to the player by the normal reserved number display means 533, etc.

[0079] The special symbol starting means 523 is for starting the variation of symbols by the special symbol display means 532, and is provided with, for example, two upper and lower start winning means 523a, 523b, an opening / closing means 546 for opening and closing the lower start winning means 523b, and a game ball detection means (not shown) for detecting the game balls that have won the start winning means 523a, 523b, respectively, and is disposed, for example, below the center case 521. The upper start winning means 523a is a non-opening / closing type winning means that does not have an opening / closing means, etc., and is disposed directly below the center drop part of the stage 535 with an upward opening. The lower start winning means 523b is an opening / closing type winning means which can be switched by the opening / closing means 546 between an open state in which the game ball can win a prize, and a closed state in which a prize is not possible (or a prize is more difficult to win than in the open state), and is arranged below the upper start winning means 523a, and is configured so that the opening / closing means 546 changes from a closed state to an open state for a predetermined time in the normal profit state which occurs when the stopped pattern after the change of the normal pattern display means 531 becomes a winning pattern.

[0080] The special pattern display means 532 is for variably displaying special patterns, and is composed of a display means such as a 7-segment type capable of variably displaying one or more special patterns, for example one special pattern, and when the special pattern start means 523 detects a game ball (when the pattern start condition is met), that is, when the game ball enters either of the two upper and lower start winning means 523a, 523b, the special pattern is variably displayed for a predetermined period of time, and if the jackpot determination random number value contained in the special random number information obtained at the time of the game ball entering the start winning means 523a, 523b matches a predetermined jackpot determination value, it stops in a predetermined jackpot mode, and if they do not match, it stops in, for example, a miss mode.

[0081] The special random number information acquired when the game ball enters the special symbol starting means 523 is reserved and stored up to a predetermined upper limit, for example, up to four pieces, and is consumed in sequence each time the special symbol display means 532 starts changing the patterns. The number of stored special random number information (special reserved number) is notified to the player by the first special reserved number display means 534, the second special reserved number display means 549 described later, etc.

[0082] The big prize means 524 is an opening / closing type prize means equipped with an opening / closing plate 547 that can be switched between an open state in which the game ball can win a prize and a closed state in which the game ball cannot win a prize, and is arranged, for example, below the special pattern starting means 523, and in a special profit state that occurs when the stopped pattern after the change of the special pattern display means 532 becomes a big win state, the opening / closing plate 547 opens to the front according to a predetermined opening pattern, allowing the game ball that falls on it to win a prize inside.

[0083] The image display means 526 also includes a performance pattern display means 548, a second special reserved number display means 549, etc. The performance pattern display means 548 displays the performance pattern P in a variable manner in parallel with the display of the special pattern by the special pattern display means 532. The performance pattern P has a plurality of pattern rows (three in the left and right direction in the example of FIG. 12) consisting of a plurality of patterns including numerical patterns and other patterns, and starts to vary by vertical scrolling or the like for each pattern row according to a predetermined variation pattern almost simultaneously with the start of variation of the special pattern, and finally stops almost simultaneously with the stop of the special pattern so that the stopped pattern on a predetermined effective line becomes a predetermined mode. In the performance pattern P, for example, when all the stopped patterns on the effective line are the same, it is a big win performance mode, and otherwise it is a miss performance mode, and when the special pattern becomes a big win mode or a miss mode, the performance pattern P becomes a big win performance mode or a miss performance mode.

[0084] The second special reserved number display means 549 is for notifying the number of special reserved items, and can display reserved display images Q4-Q1 for the number of special reserved items (maximum 4 items) and a changing reserved image Q0 corresponding to the changing performance pattern P at a predetermined position on the display screen 526a, for example, at the bottom. When the number of special reserved items increases due to the entry of a game ball into the special pattern start means 523, the second special reserved number display means 549 displays one additional reserved display image Q1- at the end of the queue (for example, the left end side), and when a new change of the special pattern starts and the number of special reserved items decreases, for example, the changing reserved image Q0 is erased and the reserved display image Q1- is shifted by one toward the front of the queue (for example, the right side), and the pushed-out top reserved display image Q1 is changed to the new changing reserved image Q0.

[0085] In addition to the movable performance means 536, an illumination device 550 is arranged on various game components such as the center case 521 on the game board 505. The illumination device 550 includes an LED board 551 having an LED 551a arranged on the front side, and a light-emitting lens section 552 arranged in front of the LED board 551. The light-emitting lens section 552 is composed of a light-transmitting section provided on at least a part of the decorative frame 528. The light-emitting lens section 552 is subjected to a light diffusion treatment such as uneven processing in order to make the LED board 551 and the like inside difficult to see from the front side and to appropriately diffuse the light emitted from the LED 551a.

[0086] FIG. 13 is a schematic block diagram of the control system of this pachinko machine. In FIG. 13, the main control board 561 controls the overall game operation, and is connected to the normal symbol starting means 522, special symbol starting means 523, big prize means 524, normal prize means 525, normal symbol display means 531, special symbol display means 532, normal reserved number display means 533, first special reserved number display means 534, etc. on the game board 505 via, for example, a relay board not shown, etc., and below it are connected a sub-control board 562 which controls the performance such as image display by the image display means 526, audio output by speakers SP1, SP2, light emission by the illumination devices 510, 540, 550, and movable body drive by the drive means 542 based on control commands from the main control board 561, a payout control board 563 which controls the payout means 514 based on control commands from the main control board 561, and a launch control board 564 which controls the launch means 506 based on launch control signals from this payout control board 563, etc.

[0087] Next, the configuration of the movable illumination device 540 will be described with reference to Figs. 14 to 18 and the like. As shown in Figs. 14 to 17 and the like, the movable illumination device 540 is composed of a front cover body 571, a base body 572, and an LED board 574 on which a plurality of LEDs (light sources) 573 are arranged. The front cover body 571 is made of a synthetic resin having translucency, and integrally includes a front plate 575 and an outer peripheral plate 576 that is extended backward along the outer periphery of the front plate 575. The front plate 575 of the front cover body 571 is subjected to a non-translucent treatment on the front side (non-translucent portion 577) except for a character area corresponding to the character string "Kappa Legend" written in horizontal Gothic font, for example, and thus a translucent character portion (translucent portion) 578 constituting the horizontal character string "Kappa Legend" is formed on the front plate 575. 14, this light-transmitting character portion 578 is composed of a plurality of (here, 14) light-transmitting regions 578a-578n separated from one another by non-light-transmitting portions 577. For example, the character "ka" is composed of one light-transmitting region 578a, and the character "tsu" is composed of three light-transmitting regions 578b-578d.

[0088] The non-light-transmitting treatment for forming the non-light-transmitting portion 577 may be any treatment such as plating, pasting of a non-light-transmitting sheet, etc. The non-light-transmitting portion 577 is not required to be completely non-light-transmitting, but only needs to have a sufficiently low light transmittance compared to the light-transmitting character portion 578. It is also desirable to apply the non-light-transmitting treatment to the outer surface side of the outer peripheral plate 576 of the front cover body 571.

[0089] The front plate 575 of the front cover body 571 is formed in a horizontally elongated shape that is slightly larger than the outline of the horizontally written character string "Kappa Legend" that constitutes the light-transmitting character portion 578, and a non-light-transmitting border portion 577a of a substantially constant width is formed in a forward-protruding shape along the outer periphery of each character that constitutes the light-transmitting character portion 578. In this embodiment, the outside of the non-light-transmitting border portion 577a is the non-light-transmitting portion 577, and the inside of the non-light-transmitting border portion 577a is the light-transmitting character portion 578. Note that the non-light-transmitting border portion 577a does not necessarily have to be formed in a forward-protruding shape, and may be formed to the same thickness as the other non-light-transmitting portions 577.

[0090] As shown in FIG. 17, on the inner surface of the front cover body 571, lens cutting and other light diffusion treatments are applied at least to the area corresponding to the translucent letter portion 578 in order to make the LED board 574 and the like less visible from the front and to appropriately diffuse the light emitted from the LED 573 (light diffusion portion 579).

[0091] In FIG. 17, an example in which the light diffusion treatment is applied not only to the region behind the light-transmitting character part 578 but also to the region behind the non-light-transmitting part 577 is shown, but the light diffusion treatment may be applied only to the region behind the light-transmitting character part 578, and not to the region behind the non-light-transmitting part 577. When the light diffusion treatment is applied to the rear side of the non-light-transmitting part 577, the light diffusion treatment may be applied only to a certain region corresponding to the front side of the LED 573, not to the entire non-light-transmitting part 577. When the light diffusion treatment is applied to both the light-transmitting character part 578 and the non-light-transmitting part 577, the type of light diffusion treatment (for example, the type of lens cutting) may be different between the rear side of the light-transmitting character part 578 and the rear side of the non-light-transmitting part 577. In this case, the type of lens cutting may be any type, such as ball cutting, knurling, diamond cutting, ice cutting, etc. Further, regarding the transparent character portion 578, the side of the transparent character portion 578 (i.e., the front side) may be subjected to the same or different type of lens cut processing as that on the inner side.

[0092] The front cover body 571 is detachably fixed to the front side of the base body 572 by means of screws or the like. The base body 572 is made of a synthetic resin having no translucency, and integrally includes a front plate 581 formed in substantially the same shape as the outer shape of the front cover body 571, and an outer peripheral plate 582 extending rearward along the outer periphery of the front plate 581, and the front cover body 571 is fixed to the front side of the front plate 581. The rear side of the front cover body 571 is substantially closed by the front plate 581 of the base body 572, so that a light emitting chamber 583 is formed in the front cover body 571. Rail connection parts 584 are provided on both the left and right ends of the base body 572 so as to be slidably mounted on the guide rails 543.

[0093] The LED board 574 is shaped to fit the inner surface of the outer peripheral plate 576 of the front cover body 571, and is equipped with a board main body 585 which is larger than the translucent character portion 578 and whose edges are formed to fit the outer shape of the translucent character portion 578, a number of LEDs 573 arranged on the front side of the board main body 585, and a connector 586 arranged on the back side of the board main body 585, and is fixed to the front plate 581 of the base body 572 by screwing or the like while being positioned at a predetermined rear position within the light-emitting chamber 583 and removably attached.

[0094] A boss 587 for supporting the board is formed on the front plate 581 of the base body 572 so as to protrude forward, and this boss 587 supports the LED board 574 while maintaining a certain gap between it and the base body 572. A harness 588 connected to the connector 586 is led out to the rear side of the movable illumination device 540 through an opening 589 formed in the base body 572, and is connected to the sub-control board 562 via a relay board or the like.

[0095] On the LED board 574, 3×10=30 LEDs 573 are arranged corresponding to the light-transmitting character section 578 on the front cover body 571 side, that is, the character string "Kappa Legend". That is, on the LED board 574, as shown in FIG. 18, a plurality of LED rows (light source rows) each consisting of a plurality of (three in this case) LEDs 573 arranged in the short side direction (here, the vertical direction which is the width direction of the character string) of the movable illumination device 540 are arranged in a plurality of (ten pairs of A to J in this case) in the long side direction (here, the horizontal direction which is the arrangement direction of the character string). The LEDs 573 on the LED board 574 are controlled to emit light by different channels for each LED row. This makes it possible to easily perform light emission control such as sequentially changing the light emission state (light emission color and light emission mode such as on / off) of the LEDs 573 in the arrangement direction of the character string.

[0096] 16, the 30 LEDs 573 are distinguished by adding the reference characters A to J (FIG. 18) indicating the LED column to which they belong, and the reference characters 1 to 3 indicating the number within each LED column. For example, the first LED 573 belonging to LED column A is LED 573A1, and the third LED 573 belonging to LED column B is LED 573B3.

[0097] Moreover, all of the 30 LEDs 573 are arranged on the rear side of the non-transparent border 577a along the boundary between the light-transmitting character portion 578 and the non-transparent border 577a so that at least a part of each LED 573 overlaps the rear side of the non-transparent portion 577 in a front view. Specifically, the LEDs 573 (here, LEDs 573G3, 573I1, 573I2, and 573J2) arranged corresponding to the non-transparent portion 577 (middle non-transparent portion) sandwiched between a plurality of light-transmitting character portions 578 adjacent to each other are arranged on the rear side of the non-transparent portion 577 in correspondence with the approximate center (positions approximately equidistant from each light-transmitting character portion 578). Moreover, the LEDs 573 (here, 573F1) arranged corresponding to the non-transparent portion 577 substantially surrounded by the light-transmitting character portions 578 are arranged on the rear side of the non-transparent portion 577 in correspondence with the approximate center (positions approximately equidistant from the surrounding light-transmitting character portions 578). In these cases, depending on the size relationship between the width of the non-transmitting portion 577 and the LED 573, if the LED 573 is larger (for example, LED 573I1), a portion of the LED 573 will extend beyond the transmissive character portion 578, but if the LED 573 is smaller (for example, LED 573J2, 573J3), the entire LED 573 will overlap the rear side of the non-transmitting portion 577.

[0098] On the other hand, when the other LEDs 573, that is, the non-transmitting portion 577 having a sufficient width is in contact with the translucent character portion 578, the LEDs 573 (here, LEDs 573A1-573A3, 573B1-573B3, etc.) arranged corresponding to the non-transmitting portion 577 are arranged so that the edges of the LEDs 573 approximately coincide with the front-rear boundary between the non-transmitting portion 577 and the translucent character portion 578. In this case, it is preferable that the edges of the LEDs 573 do not extend beyond the translucent character portion 578, but they may be arranged so that they extend partially.

[0099] In this way, by positioning the LED 573 behind the non-translucent portion 577, the light emitted from the LED 573 directly ahead is not (or is barely) irradiated directly onto the translucent letter portion 578, thereby eliminating spot light and reducing the brightness difference of the translucent letter portion 578.

[0100] Among the plurality of light-transmitting regions 578a-578n, in a specific light-transmitting region (here, light-transmitting regions 578a, 578d-578f, 578h, 578i, 578n) in which the plurality of LEDs 573 are arranged, the LEDs (specific light sources) 573 corresponding to each specific light-transmitting region are arranged as follows: That is, each LED 573 corresponding to a specific light-transmitting region is arranged such that an entire straight line path to at least one of the other LEDs 573 corresponding to the specific light-transmitting region passes through the specific light-transmitting region in a front view.

[0101] Specifically, among the LEDs 573A1 to 573A3 and 573B1 to 573B3 corresponding to the specific light-transmitting region 578a, for the LED 573A1, the straight path L1 for the LED 573A2 and the straight path L2 for the LED 573A3 all pass through the specific light-transmitting region 578a in a front view. Similarly, for the LED 573A2, the straight path L1 for the LED 573A1 and the straight path L3 for the LED 573B1 all pass through the specific light-transmitting region 578a in a front view. The same is true for the other LEDs 573A3 and 573B1 to B3. As a result, the light-emitting regions of the multiple LEDs 573 overlap each other in the specific light-transmitting region, making it possible to further reduce the brightness difference of the light-transmitting character portion 578 due to point light.

[0102] 16, the LED 573 is formed in a substantially rectangular shape, and three terminals 569a-569c, 569d-569f are arranged on predetermined opposite sides 573a, 573b of the four sides. Then, wiring patterns 570a-570c, 570d-570f are respectively drawn out straight and parallel from each of the terminals 569a-569c, 569d-569f in a direction perpendicular to the predetermined opposite sides 573a, 573b for at least a predetermined distance X, and then bent in any direction or directly connected to a via or the like. 16, LEDs 573 that are disposed near the edge of the LED substrate 574 and are particularly located less than the predetermined distance X from the substrate edge are disposed such that a side 573c on which no terminals are provided, different from the predetermined opposite sides 573a, 573b on which the terminals 569a-569c, 569d-569f are provided, faces the edge of the LED substrate 574. This has the advantage that the wiring pattern can be easily routed even though the LEDs 573 must be disposed near the edge of the LED substrate 574.

[0103] As described above, the pachinko machine of this embodiment is equipped with a movable illumination device (illumination device) 540 having a translucent character portion (translucent portion) 578 and a plurality of LEDs (light sources) 573 that illuminate the translucent character portion 578, and a non-translucent portion 577 is provided on the outer edge of the translucent character portion 578, and the LEDs 573 are positioned behind the non-translucent portion 577. Therefore, it is possible to improve the appearance when illuminated by reducing the brightness difference of the translucent character portion 578 caused by the point light of the movable illumination device 540.

[0104] Furthermore, the LED 573 is positioned at the boundary between the translucent letter portion 578 and the non-translucent portion 577 so that at least a portion of it overlaps the rear of the non-translucent portion 577 when viewed from the front of the movable illumination device 540, and further, for the intermediate non-translucent portion of the non-translucent portion 577 that is sandwiched on both sides by the translucent letter portions 578, the LED 573 is positioned behind it, corresponding to approximately the center in the width direction. This makes it possible to eliminate spot lights and make the entire translucent letter portion 578 emit light more brightly and as evenly as possible.

[0105] In addition, the light-transmitting character portion 578 has a plurality of light-transmitting regions 578a-578n separated from one another by non-light-transmitting portions 577, and a plurality of LEDs 573 (hereinafter, specific light sources) are arranged behind the outer periphery of the non-light-transmitting portion 577 in correspondence with specific light-transmitting regions among the plurality of light-transmitting regions 578a-578n. These specific light sources are arranged so that the entire straight line path for at least one of the other specific light sources passes through the specific light-transmitting region when viewed from the front of the movable illumination device 540. Therefore, the light-emitting regions of the multiple specific light sources overlap each other within the specific light-transmitting region, thereby making it possible to reduce the brightness difference in the light-transmitting character portion 578 caused by point light.

[0106] Furthermore, LED rows (rows of light sources) consisting of a plurality of LEDs 573 arranged in the short direction of the movable illumination device 540 are arranged in multiple rows in the long direction of the movable illumination device 540, and the LEDs 573 are controlled by different channels for each LED row. This makes it possible to easily perform illumination control such as sequentially changing the light emission state of the LEDs 573 (light emission color, light emission mode such as on / off, etc.) in the arrangement direction of the character string.

[0107] In addition, the LED board 574 is formed so that at least a portion of its edge conforms to the outline of the light-transmitting character portion 578, and the LEDs 573 near the edge of the LED board 574 are positioned so that the side other than the specified opposite side on which the terminals are provided faces the edge of the LED board 574. This has the advantage that even though the LEDs 573 must be positioned near the edge of the LED board 574, it is easy to route the wiring pattern.

[0108] 19 to 22 show a third embodiment of the present invention, which is a partial modification of the second embodiment, in which a non-translucent character section made of a non-translucent section is provided in the translucent section, and LEDs are arranged behind the non-translucent character section. This embodiment differs from the second embodiment only in the arrangement of the translucent section / non-translucent section in the movable illumination device, and the associated arrangement of the LEDs and the shape of the movable illumination device. The configuration of the movable illumination device will be described below, focusing on the differences from the second embodiment.

[0109] 19 to 21, the movable illumination device 590 of this embodiment is configured with a front cover body 591, a base body 592, and an LED board 594 on which a plurality of LEDs (light sources) 593 are arranged, similarly to the movable illumination device 540 of the second embodiment. The front cover body 591 is made of a translucent synthetic resin, and integrally includes a front plate 595 and an outer peripheral plate 596 that is provided so as to extend rearward along the outer periphery of the front plate 595. In front plate 595 of front cover body 591, a non-light-transmitting treatment is applied to the front side of a character area (non-light-transmitting character portion 597a) corresponding to the character string "Kappa Legend" written in horizontal Gothic font, and a frame area (non-light-transmitting frame portion 597b) surrounding each of these characters individually, so that the characters "KA", "TT", "PA", "DEN", ​​and "SETSU" constituting non-light-transmitting character portion 597a are formed in five rectangular light-transmitting portions 598 on front plate 595. Front plate 595 of front cover body 591 is formed in a horizontally elongated rectangular shape along the outer shape of non-light-transmitting frame portion 597b.

[0110] The non-light-transmitting treatment for forming the non-light-transmitting portions 597a and 597b may be any treatment such as plating, attachment of a non-light-transmitting sheet, etc. The non-light-transmitting portions 597a and 597b are not required to be completely non-light-transmitting, but only need to have a sufficiently low light transmittance compared to the light-transmitting portion 598. It is also desirable to apply the non-light-transmitting treatment to the outer surface side of the outer peripheral plate 596 of the front cover body 591.

[0111] In addition, as shown in FIG. 21, on the inner surface of the front cover body 591, lens cutting processing or other light diffusion processing is applied to at least the area corresponding to the translucent portion 598 in order to make the LED board 594, etc., less visible from the front and to appropriately diffuse the light emitted from the LED 593 (light diffusion portion 599).

[0112] 21 shows an example in which the light diffusion treatment is performed not only on the region behind the light-transmitting portion 598 but also on the region behind the non-light-transmitting portions 597a and 597b, but the light diffusion treatment may be performed only on the region behind the light-transmitting portion 598, and not on the region behind the non-light-transmitting portions 597a and 597b. When the light diffusion treatment is performed on the rear sides of the non-light-transmitting portions 597a and 597b, the light diffusion treatment may be performed only on a certain region corresponding to the front side of the LED 593, not on the entire non-light-transmitting portions 597a and 597b. When the light diffusion treatment is performed on both the light-transmitting portion 598 and the non-light-transmitting portions 597a and 597b, the type of light diffusion treatment (for example, the type of lens cut processing) may be different between the rear side of the light-transmitting portion 598 and the rear side of the non-light-transmitting portions 597a and 597b. In this case, the type of lens cut processing may be any type, such as ball cut processing, knurling processing, diamond cut processing, ice cut processing, etc. In addition, with respect to the light-transmitting portion 598, the light-transmitting portion 598 side (i.e., the front side) may be subjected to the same or different type of lens cut processing as that on the inner side.

[0113] The front cover body 591 is detachably fixed to the front side of the base body 592 by screwing or the like. The base body 592 is made of a synthetic resin having no translucency, and integrally includes a front plate 601 formed in substantially the same shape as the outer shape of the front cover body 591, and an outer peripheral plate 602 extending rearward along the outer periphery of the front plate 601, and the front cover body 591 is fixed to the front side of the front plate 601. The rear side of the front cover body 591 is substantially closed by the front plate 601 of the base body 592, so that a light emitting chamber 603 is formed in the front cover body 591. Rail connection parts 604 that are slidably attached to the guide rails 543 are provided on both the left and right ends of the base body 592.

[0114] The LED board 594 comprises a board main body 605 formed in a horizontally elongated rectangular shape that conforms to the inner surface of the outer peripheral plate 596 of the front cover body 591, a plurality of LEDs 593 arranged on the front side of the board main body 605, and a connector 606 arranged on the back side of the board main body 605, and is disposed at a predetermined rear position within the light-emitting chamber 603 and is fixed to the front plate 601 of the base body 592 by screwing or the like in a manner that allows it to be freely attached and detached.

[0115] A boss 607 for supporting the board is formed on the front plate 601 of the base body 592 so as to protrude forward, and this boss 607 supports the LED board 594 with a certain gap between it and the base body 592. A harness 608 connected to the connector 606 is led out to the rear side of the movable illumination device 590 through an opening 609 formed in the base body 592, and is connected to the sub-control board 562 via a relay board or the like.

[0116] On the LED board 594, 3×9=27 LEDs 593 are arranged corresponding to the non-translucent character part 597a on the front cover body 591 side, that is, the character string "Kappa Legend". That is, on the LED board 594, as shown in FIG. 22, a plurality of LED rows (light source rows) each consisting of a plurality of (three in this case) LEDs 593 arranged in the short side direction (here, the vertical direction which is the width direction of the character string) of the movable illumination device 590 are arranged in a plurality of (nine sets of A to I in this case) in the long side direction (here, the left-right direction which is the arrangement direction of the character string) of the movable illumination device 590. The LEDs 593 on the LED board 594 are controlled to emit light by different channels for each LED row. This makes it possible to easily perform light emission control such as sequentially changing the light emission state (light emission color and light emission mode such as on / off) of the LEDs 593 in the arrangement direction of the character string.

[0117] 20, the 27 LEDs 593 are distinguished by adding the symbols A to I (FIG. 22) indicating the LED column to which they belong, and the symbols 1 to 3 indicating the number within each LED column. For example, the first LED 593 belonging to LED column A is LED 593A1, and the third LED 593 belonging to LED column B is LED 593B3.

[0118] All of the 27 LEDs 593 are disposed behind the non-translucent character portion 597a, and are disposed at approximately the center in the width direction of the non-translucent character portion 597a when viewed from the front. This means that the light emitted from the LEDs 593 directly ahead is not (or is minimally) irradiated directly onto the translucent portion 598, eliminating point light and reducing the brightness difference of the translucent portion 598, and making the silhouette of the non-translucent character portion 597a stand out more clearly.

[0119] 23 and 24 show a fourth embodiment of the present invention, which is a partial modification of the third embodiment, in which LEDs 593 are arranged not only behind the non-light-transmitting character portion 597a but also behind the non-light-transmitting frame portion 597b. This embodiment differs from the third embodiment only in the arrangement of the LEDs 593. The following description will focus on the differences from the third embodiment.

[0120] In the LED board 594 of this embodiment, 3×16=48 LEDs 593 are arranged corresponding to the non-translucent character part 597a and the non-translucent frame part 597b on the front cover body 591 side. That is, as shown in FIG. 24, the LED board 594 has a plurality of LED rows (light source rows) (here, 16 pairs of A to P) arranged in the longitudinal direction (here, the left-right direction in which the character strings are arranged) of the movable illumination device 590, each of which is composed of a plurality of (three here) LEDs 593 arranged in the short side direction (here, the up-down direction in which the character strings are arranged) of the movable illumination device 590. The LEDs 593 on the LED board 594 are controlled to emit light by different channels for each LED row. This makes it possible to easily perform light emission control such as sequentially changing the light emission state (light emission color and light emission mode such as on / off) of the LEDs 593 in the arrangement direction of the character strings.

[0121] 23, the 48 LEDs 593 are distinguished by adding the symbols A to P indicating the LED column to which they belong and the symbols 1 to 3 indicating the number within each LED column. For example, the first LED 593 belonging to LED column A is LED 593A1, and the third LED 593 belonging to LED column B is LED 593B3.

[0122] All of the 48 LEDs 593 are disposed behind either the non-light-transmitting character portion 597a or the non-light-transmitting frame portion 597b. The LEDs 593 (e.g., LEDs 593B2, 593B3) corresponding to the non-light-transmitting character portion 597a disposed inside the light-transmitting portion 598 are disposed substantially in the center in the width direction of the non-light-transmitting character portion 597a when viewed from the front. Furthermore, of the LEDs 593 corresponding to the non-light-transmitting frame portion 597b arranged outside the light-transmitting portion 598, the LEDs 593 (e.g., LEDs 593D2, 593G2, etc.) arranged corresponding to the non-light-transmitting frame portion 597b sandwiched between two light-transmitting portions 598 are arranged behind the approximate center of the non-light-transmitting frame portion 597b (at a position approximately equidistant from each non-light-transmitting frame portion 597b).Other LEDs 593, i.e., when a non-light-transmitting frame portion 597b of sufficient width is in contact with the light-transmitting portion 598, the LEDs 593 (here, LEDs 593A1 to 593A3, 593B1, 593C3, etc.) arranged corresponding to the non-light-transmitting frame portion 597b are arranged so that the edges of the LEDs 593 approximately coincide with the front-to-back boundary between the non-light-transmitting frame portion 597b and the light-transmitting portion 598. In either case, it is preferable that the edge of LED 593 does not extend beyond light transmitting portion 598, but LED 593 may be disposed so that it extends partially beyond the light transmitting portion.

[0123] By arranging the LEDs 593 in this manner, the light emitted from the LEDs 593 directly ahead is not (or is barely) irradiated directly onto the translucent portion 598, so that it is possible to eliminate point light and reduce the brightness difference of the translucent portion 598, and also to make the silhouette of the non-translucent letter portion 597a stand out more clearly.

[0124] 23, the LED 593 is formed in a substantially rectangular shape, and three terminals 569a-569c, 569d-569f are arranged on predetermined opposite sides 593a, 593b of the four sides. Then, wiring patterns 570a-570c, 570d-570f are respectively drawn out straight and parallel from each of the terminals 569a-569c, 569d-569f in a direction perpendicular to the predetermined opposite sides 593a, 593b for at least a predetermined distance X, and then bent in any direction or directly connected to a via or the like. Therefore, the LEDs 593 (LEDs 593A1 to 593A3, 593B1, etc.) that are arranged near the edge of the LED substrate 594 formed in a horizontally elongated rectangular shape and that are particularly far from the edge of the substrate are arranged so that the side 593c on which no terminals are provided, which is different from the predetermined opposite sides 593a and 593b on which the terminals 569a to 569c and 569d to 569f are provided, faces the edge of the LED substrate 594, as shown in a partially enlarged view of FIG. 23. The LEDs 593 are arranged to avoid the vicinity of the corners of the LED substrate 594 (for example, LED 593A1). This has the advantage that the wiring pattern can be easily routed even when the LEDs 593 must be arranged near the edge of the LED substrate 594 as in this embodiment.

[0125] Although the embodiment of the present invention has been described above in detail, the present invention is not limited to this embodiment, and various modifications are possible within the scope of the present invention. For example, the first embodiment and the second to fourth embodiments are embodied as completely different gaming machines, but it goes without saying that the former and the latter can be embodied as the same gaming machine by appropriately combining them. For example, the gaming machines according to the second to fourth embodiments can adopt the same base configuration as the gaming machine according to the first embodiment, and it is also possible to adopt the same illumination device as the gaming machines according to the second to fourth embodiments on the gaming machine according to the first embodiment.

[0126] In the first embodiment, an example was shown in which the relationship between the diameter φ of the heat dissipation through-hole, the diameter φ1 of the signal conduction via, and the diameter φ2 of the power conduction via was φ1<φ≈φ2, but this is not limited thereto, and for example, φ1≈φ<φ2 or φ1≈φ≈φ2 may be used. In addition, when the diameter of the heat dissipation through-hole is made different for each heat-generating component, the diameter of the heat dissipation through-hole corresponding to heat-generating component A may be φa and the diameter of the heat dissipation through-hole corresponding to heat-generating component B may be φ1≈φa<φb≈φ2.

[0127] In the first embodiment, the heat-generating component 75 and its conductor portion 151 are square, and the heat dissipation through holes 140a are arranged in a matrix (3 x 3) with the same number of vertical and horizontal holes within the area corresponding to the square conductor portion 151. However, if the heat-generating component and / or its conductor portion is rectangular rather than square, the heat dissipation through holes may be arranged in a matrix (e.g. 3 x 5) with different numbers of vertical and horizontal holes.

[0128] 10, the minimum width of the ground wiring path 138 inside the peripheral margin 171 in the portion other than the recess 161 is made smaller than the minimum width of the ground wiring path 138 inside the peripheral margin 171 in the portion of the recess 161, but the two may be approximately the same. Also, in the example of Fig. 10, the ground wiring path 138 is disposed between the peripheral margin 171 and the signal wiring path 134, etc., but the signal wiring path, etc. may be disposed inside the peripheral margin 171 without the ground wiring path in between.

[0129] The configurations of the movable illumination devices of the second to fourth embodiments can be similarly applied to the illumination device 50 fixedly disposed on the game components on the game board 5, such as the center case 21, and the illumination device 10 fixedly disposed on the front frame 4 side. Of course, they can also be similarly applied to the case where a movable illumination device is provided on the front frame 4 side.

[0130] In the second embodiment, an example was shown in which the light-transmitting portion was in the shape of letters (light-transmitting letter portion 78), but the light-transmitting portion in this case is not limited to being in the shape of letters, and may be any shape, such as a graphic such as a logo mark, or a pattern such as a character. Also, in the third and fourth embodiments, an example was shown in which a non-light-transmitting portion in the shape of letters (non-light-transmitting letter portion 97a) was arranged in the light-transmitting portion, but the non-light-transmitting portion in this case is not limited to being in the shape of letters, and may be any shape, such as a graphic such as a logo mark, or a pattern such as a character.

[0131] In the second to fourth embodiments, the translucent and non-translucent portions are formed by applying a non-translucent treatment to a portion of the translucent front cover body 71. However, the translucent and non-translucent portions may also be formed, for example, by combining a non-translucent first member with a translucent second member (for example, by fitting the second member to the back side of a first member having letter-shaped openings).

[0132] In the second to fourth embodiments, the illumination device is disposed facing the front of the gaming machine main body 1, but the illumination device may be disposed at an angle to the front of the gaming machine main body 1, for example, so that the front faces the player, for example, by disposing the illumination device on the upper side of the front frame 4 diagonally downward. In this case, it is preferable that the LED (light source) of the illumination device is disposed behind the non-transmitting part when viewed from the front of the illumination device, not when viewed from the front of the gaming machine main body 1.

[0133] In the second to fourth embodiments, the number of LEDs belonging to the LED row of the same channel is three, but it may be two or four or more.

[0134] Two or more of the first to fourth embodiments may be appropriately combined. In addition, although the embodiment shows an example in which the present invention is applied to a pachinko machine, the present invention can be similarly applied to various gaming machines such as an arrange ball machine and a slot machine.
