Wiring for transmitting a command signal is connected.

  The control signal transmitted from the main board 11 toward the effect control board 12 is an effect control command transmitted and received as an electric signal, for example. The effect control command includes, for example, a change pattern designation command indicating a change pattern indicating a change mode such as a change time of an effect symbol, a type of reach effect, and the presence / absence of a pseudo-ream.

  The game control microcomputer 100 mounted on the main board 11 is, for example, a one-chip microcomputer, and provides a ROM 101 (ReadOnlyMemory 101) for storing a game control program, fixed data, and the like, and a game control work area. RAM 102 (Random Access Memory 102), a CPU 103 (Central Processing Unit 103) that executes a control program by executing a game control program, a random number circuit 104 that updates numeric data indicating a random number value independently of the CPU 103, and an I / O 105 (Input / Outputport 105). As an example, in the game control microcomputer 100, a process for controlling the progress of the game in the pachinko gaming machine 1 is executed by the CPU 103 executing a program read from the ROM 101.

  As shown in FIG. 2, the effect control board 12 is a sub-side control board independent of the main board 11, receives the control signal transmitted from the main board 11 via the relay board 15, and produces an effect display.

And are installed. As an example, in the effect control board 12, when the effect control CPU 120 executes an effect control program read from the ROM 121, a process for controlling the effect operation by the effect electric component is executed. In addition to the effect control program, the ROM 121 stores various data tables used for controlling the effect operation.

  Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko gaming machine 1, based on the fact that the game ball has passed through the passing gate 41 provided in the gaming area 10, the normal game with the normal symbol display 20 is started. After the start of the normal symbol change, if the specified time, which is the normal symbol change time, has elapsed, and the normal symbols other than the normal symbol are displayed in a stopped state, the normal symbol change display result is “out of normal”. Become. If the specific normal symbol (the symbol per ordinary symbol) is stopped and displayed, the variation display result of the ordinary symbol becomes “per ordinary symbol”, and the release control in which the movable plate of the ordinary variable winning ball apparatus 6B is retracted from the game area 10 is performed. The normal opening control is performed to return to the closed position protruding into the game area 10 when a predetermined time has elapsed.

  Based on the fact that the first start condition is satisfied after the first special condition game or the big hit game state has ended, for example, after the first start condition is satisfied because the game ball has won the first start winning opening, etc. Then, a special game is started by the first special symbol display 4A. In addition, after the second start condition is established because the game ball has won the second start winning opening, etc., the second start condition is established, for example, due to the end of the previous special game or the big hit game state. Based on this, a special game is started by the second special symbol display 4B.

  In the special game, after starting the variable display of the special symbol, the fixed special symbol (special graphic display result) is derived and displayed when the variable display time elapses. At this time, if a specific special symbol (big hit symbol) is displayed in a stopped state, the result is “big hit” as the specific display result, and if a special symbol different from the big hit symbol is displayed in a stopped state, it becomes “out of place”. After the fluctuation display result in the special figure game becomes “big hit”, the game is controlled to the big hit gaming state as a specific gaming state in which a round advantageous to the player (also referred to as “round game”) is executed a predetermined number of times.

  In the big hit gaming state, a special winning prize ball device 7 has a special prize opening door for a period until a predetermined upper limit time (for example, 29 seconds or 0.1 second) elapses or a predetermined number (for example, 9) of winning balls. In the period until the occurrence of, the grand prize opening is opened. Thereby, the round which makes the special variable winning ball apparatus 7 the 1st state (open state) advantageous for a player is performed.

  A special prize-winning ball device that receives a game ball falling on the surface of the game board 2 and then closes the big prize-winning slot, with the grand prize-winning door that has opened the grand prize-winning port during the round. 7 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. The round that is the opening cycle of the big prize opening can be repeatedly executed until the number of executions reaches a predetermined upper limit number (for example, “16”, etc.).

  In the effect symbol display areas 5L, 5C, and 5R of the effect display device 5, in response to the start of the special symbol game, the effect symbol variable display is started. In the period from the start of the variation display of the effect symbol to the end of the variation display, the variation display state of the effect symbol may be a predetermined reach state. The reach state is a display in which variation continues for effect symbols that are not yet stopped when the effect symbols that are stopped and displayed in the display area of the effect display device 5 constitute a part of the jackpot combination. A state or a display state in which all or a part of the effect symbols change synchronously while constituting all or part of the jackpot combination.

  As a confirmed special symbol in the special figure game, among the multiple types of big hit combinations, the fixed effect symbol that is a predetermined normal big hit combination (also referred to as “non-probable variable big hit combination”) is stopped and displayed, and the variation display result is “non-probable big hit bonus”. ”Is controlled to the big hit state, and after the end, time reduction control (time reduction control) is performed. By performing the time reduction control, the special symbol change display time (special figure change time) in the special figure game is shortened compared to the normal state. In the short-time control, so-called electric Chu support is performed in which the winning frequency of the normal symbol is increased and the winning frequency to the normal variable winning ball apparatus 6B is increased. In the time-saving control, one of the conditions is established first, that is, a special game is executed a predetermined number of times (for example, 100 times) after the big hit gaming state ends, and the fluctuation display result is “big hit”. Sometimes it just needs to end.

  As a confirmed special symbol in the special figure game, among the multiple types of big hit combinations, the finalized design symbol that becomes a predetermined probability variable big hit combination (also referred to as “probable big hit combination”) is stopped and the fluctuation display result is “probable big hit” When it becomes, it is controlled to the big hit state, and after the end, probability variation control (probability variation control) is performed together with time reduction control. By performing the probability variation control, the probability that the variation display result is “big hit” in each special figure game is improved so as to be higher than that in the normal state. When the condition that the variable display result is “big hit” and the game is controlled again to the big hit gaming state after the end of the big hit gaming state is established, the probability variation control is performed a predetermined number of times after the big hit gaming state ends (for example, the same as the number of time reductions 100) When the special figure game is executed, the probability variation control lottery executed every time the special figure game is started after the jackpot game state is finished is determined to have “probable fall”. When it ends, etc.

  When the short-time control is performed, the normal symbol variation time (normal diagram variation time) in the regular game is shorter than that in the normal state, and the regular symbol variation display result is “normal diagram” in each regular game. The control for improving the probability of “winning” than in the normal state, and the movement control time for performing the movement control of the movable plate in the normally variable winning ball apparatus 6B based on the fact that the fluctuation display result is “normal hitting” is normal. The second start condition may be satisfied by making it easier for the game ball to pass (enter) the second start winning opening, such as a control to make the state longer than in the state and a control to increase the number of movements compared to the normal state. The control (electricity chew support control, high opening control) which is advantageous for the player by increasing the value is performed. As a result, the second start condition for executing the special figure game using the second special figure is likely to be established, and the special figure game can be executed frequently. Time to become is shortened.

If there is a winning, the special symbol display result determination, jackpot type determination, variation pattern A random number value for determination or the like is extracted, and a start winning process is executed for storing (storing) at the highest level of empty entries in the first special figure reservation storage unit or the second special figure reservation storage unit.

  Further, the CPU 103 determines whether or not to start the special game based on the presence / absence of the hold data stored in the first special figure hold storage unit or the second special figure hold storage unit, and the special figure display result. A special decision that determines (predetermines) whether or not the variation display result of a special symbol or production symbol is to be a “hit” based on numerical data indicating a random number for judgment before the variation display result is derived and displayed. The symbol normal process is executed. That is, when starting the variation display of the special figure game, the CPU 103 determines whether or not to derive and display the jackpot display result as the display result of the variation display based on the random number value stored when the start winning occurs. Processing to determine (lottery) is executed.

  Next, a variation pattern setting process for determining a variation pattern as one of a plurality of types, a special symbol variation process for performing a setting for varying a special symbol and a process for measuring an elapsed time after the special symbol starts variation, A special symbol stop process is performed to perform settings for stopping the change of the special symbol and stopping and displaying (deriving) the fixed special symbol. In addition, when the variation display result is “big hit”, the big hit release pre-processing, the big hit open process, the big hit release post-processing, and the big hit end process are performed to open and close the big winning opening in the big hit gaming state.

The holding pieces 592A and 592B of the first condenser lens 514 are locked to the left and right lens hooks 564 formed on the back surface of the intermediate holding member 504 (see FIG. 10), and the holding pieces 592A of the second condenser lens 524 are retained. , 592B are locked to left and right lens hooks 531 (see FIG. 6) formed on the front surface of the front holding member 503, and the pressing pieces 592A, 592B of the first condenser lens 519 are attached to any of the lens hooks. Are not locked (see FIG. 7).

  A plurality of condenser lens positioning bosses 593F are formed on the front surfaces of the first condenser lens 514, the second condenser lens 524, and the first condenser lens 519 so as to protrude forward, respectively. A plurality of condenser lens positioning bosses 593B are formed on the back surfaces of the optical lens 514 and the second condenser lens 524 so as to protrude rearward. Note that a condensing lens positioning boss 593B is not formed on the back surface of the first condensing lens 519.

  The first condenser lens 514 has a front condenser lens positioning boss 593F inserted into a positioning hole 594 formed in the first light guide plate LED substrate 513 (see FIG. 10), and a rear condenser lens positioning boss. 593B is inserted into a positioning hole 580 (see FIG. 11) formed in the rear holding member 505. Further, in the first condenser lens 519, the front condenser lens positioning boss 593F is inserted into a positioning hole 595A formed in the first light guide plate LED substrate 518L (see FIG. 7).

  In the second condenser lens 524, the front condenser lens positioning boss 593F is inserted into a positioning hole 530 formed in the front holding member 503 (see FIG. 6), and the rear condenser lens positioning boss 593B is rear. It is inserted into a positioning hole 595 (see FIG. 9) formed in the holding member 505.

  Each of these condensing lens positioning bosses 593F and 593B corresponds to one convex portion 590 and 591 of the plurality of the first condensing lens 514, the second condensing lens 524, and the first condensing lens 519. Since each lens is projected at a position where the width dimension (vertical width dimension or horizontal width dimension) is the longest, that is, a position where the strength is higher than a position where the width dimension is short, positioning accuracy is high. improves. Further, the front and rear surfaces of each of the first condenser lens 514, the second condenser lens 524, and the first condenser lens 519, that is, positions other than the light exit surface 590A and the entrance surface 591A, more specifically, the light exit surface 590A. In addition, since it is provided so as to protrude from the surface of the surface orthogonal to the incident surface 591A, it does not affect the incidence or emission of light. The front and rear condenser lens positioning bosses 593F and 593B are provided with the other at a position corresponding to one of the front and rear.

  As shown in FIG. 15A, the second light guide plate 521 is formed of a transparent acrylic resin plate having a predetermined plate thickness dimension L15 {plate thickness (for example, 2.5 mm)}. The upper end surface 521A is a flat surface extending in the left-right direction. The left and right oblique sides and side portions are formed along the front holding member 503 and the middle holding member 504, and the lower side portion follows the lower side portion of the movable body 301 when the movable body 301 is in the standby position. It is formed in a non-linear shape.

  A reflection part 596 for reflecting the light from the second light guide plate LED 522 and emitting it from the front surface is formed on the back surface of the second light guide plate 521 (see FIG. 24B). The reflective portion 596 is arranged in such a manner that the characters “extremely hot!” Can be displayed by light emission.

  As shown in FIG. 15B, the first light guide plate 511 is formed of a transparent acrylic resin plate having a predetermined plate thickness dimension L15 {plate thickness (for example, 2.5 mm)}. The upper end surface 511A is a flat surface extending in the left-right direction, the left end surface 511B is a flat surface extending in the vertical direction, and the right side portion and the lower side portion are along the front holding member 503 and the rear holding member 505. The display screen of the effect display device 5 and the front of the movable body 301 of the effect unit 300 can be covered.

  On the back surface of the first light guide plate 511, a reflection part 597A for reflecting the light from the first light guide plate LED 512 and emitting it from the front surface, and for reflecting the light from the first light guide plate LED 517 and emitting it from the front surface. The reflection portions 597B are respectively formed (see FIG. 24B). The reflective portion 597A is arranged in such a manner that the characters “Intense heat!” Can be emitted and displayed, and the reflective portion 597B emits an effect that decorates the periphery of the movable body 301 when the movable body 301 moves to the effect position. They are arranged in a displayable manner. The reflective portion 597A is configured to be able to emit and display the same characters as the reflective portion 596 of the second light guide plate LED 522, and the front holding member so as to overlap the first light guide plate 511 and the second light guide plate 521 in the front-rear direction. The first light guide plate 511 is disposed so as to overlap the back side of the reflecting portion 596 in a state of being held by the intermediate holding member 504 and the rear holding member 505 and held at a predetermined mounting position.

  As shown in FIG. 24B, these reflecting portions 596, 597A, and 597B are substantially the same in a cross-sectional view in the traveling direction of the light guided through the first light guide plate 511 and the second light guide plate 521. It is formed in an uneven state (rough surface) having a triangular wave shape. Specifically, it is configured by a molding method in which an uneven portion is formed on the back surface of the first light guide plate 511 or the second light guide plate 521 by a stamper or injection. For example, silk in which reflective dots are printed with white ink on an acrylic plate The reflection portion may be configured by a printing method, an adhesion dot method in which an acrylic plate and a reflection plate are attached with a dot-like adhesive material, a groove processing method, or the like.

  In this embodiment, the reflecting portions 596, 597A, and 597B are uneven portions having a substantially triangular wave shape in sectional view in the light traveling direction. However, the present invention is not limited to this, and the reflecting portions 596, 596 are not limited thereto. The cross-sectional shapes of 597A and 597B can be variously modified as long as they constitute a reflective surface capable of reflecting light forward, such as a substantially semicircular shape. In FIG. 15, the reflection portion 597A is represented as a character surrounded by a dotted line, but actually there is no dotted line, and the character is formed by a collection of the dots and the like.

  In addition, only the light from the first light guide plate LED 512 is reflected forward by the reflecting portion 597A, and the characters “Intense heat!” Are emitted and displayed, and only the light from the first light guide plate LED 517 is forwarded by the reflecting portion 597B. Description of the details of the light guide structure that is reflected and reflected by the effect is omitted. In this embodiment, only the light from the first light guide plate LED 512 is reflected by the reflecting portion 597A, and only the light from the first light guide plate LED 517 is reflected by the reflecting portion 597B. The light from the LED 512 or the light from the first light guide plate LED 517 may be reflected by both the reflection portions 597A and 597B to display light.

  In the present embodiment, characters and pictures are exemplified as display information that can be displayed by the first light guide plate 511 and the second light guide plate 521. However, in addition to these, decorations such as symbols, designs, patterns, etc. Other display information including the display may be displayed. Moreover, the 1st light-guide plate 511 and the 2nd light-guide plate 521 may not necessarily be transparent as long as it has translucency, for example, may be colored and may be made translucent.

  The first light guide plate 511 and the second light guide plate 521 are made of a transparent plate having a thickness L15 of about 2.5 mm made of an acrylic resin material, and are board plates made of a transparent synthetic resin material constituting the game board 2. Since it is thinner than the thickness dimension (for example, about 10 mm), as will be described later, expansion and contraction may occur due to a temperature change inside the pachinko gaming machine 1 when assembled in the pachinko gaming machine 1. is there.

  In the pachinko gaming machine 1, the front side of the game board 2 is closed by a glass door frame 50, and the back side is closed by a cover body (not shown), and the interior is closed by the glass door frame 50 and the cover body. The space is provided with a number of heat sources such as an effect display device 5 including a liquid crystal display, a control board, LEDs, and a drive source (motor or solenoid). Therefore, since the internal temperature when the pachinko gaming machine 1 is operating is higher than when the pachinko gaming machine 1 is not operating, the first light guide plate 511 and the second light guide plate 521 provided between the effect display device 5 and the glass window 50a are, for example, The expansion and contraction is about 1.6 mm at the maximum by the temperature change of about 40 degrees.

  Specifically, for example, in the case of the first light guide plate 511, since the warpage tolerance (intersection of flatness) is about 3 to 6 mm, for example, in a state where the light guide plate device 500 is attached to the back surface of the game board 2 The distance between the second light guide plate 521 on the front side and the distance between the rear display device 5 and other members are preferably larger than 6 mm.

  On the other hand, in the light guide plate device 500, the first light guide plate 511 and the second light guide plate 521 are partially sandwiched from the front and rear by the front holding member 503, the middle holding member 504, and the rear holding member 505. Due to the structure attached to the back side of the game board 2, the front holding member 503, the middle holding member 504, and the rear holding member 505 are touched or damaged due to assembly distortion due to manufacturing dimensional tolerances or assembly errors. In addition, there is a possibility that the front holding member 503, the middle holding member 504, and the rear holding member 505 may come into contact with each other and be damaged or broken due to expansion and contraction due to the temperature change as described above.

  Therefore, the light guide plate device 500 of the present embodiment, as will be described below, allows the first light guide plate 511 to cope with temperature changes in the pachinko gaming machine 1, manufacturing dimensional tolerances, and assembly errors. The second light guide plate 521 is attached to each front holding member 503, middle holding member 504, and rear holding member 505 with a predetermined gap (clearance).

  As shown in FIGS. 15A, 16, and 17, the first positioning boss 551 is provided on the lower left side of the upper end surface 521 </ b> A of the second light guide plate 521 so as to project from the left side of the rear surface of the front holding member 503. A first hole 601 having a circular shape when viewed from the front is formed as a first insertion portion into which can be inserted. In addition, in the lower left position of the upper end surface 521A of the second light guide plate 521, a horizontally long shape in front view as a second insertion portion into which a second positioning boss 552 protruding from the rear right side of the front holding member 503 can be inserted. The second hole 602 is formed.

  The first hole 601 and the second hole 602 are such that a straight line LN2 passing through the centers of the first hole 601 and the second hole 602 is a straight line LN1 along the upper end surface 521A (the upper side of the second light guide plate 521). Is formed in the vicinity of the upper end surface 521A so as to be parallel to the upper end surface 521A. Specifically, the distance L20 between the straight line LN1 and the straight line LN2 is longer than the length L2.5 of the second light guide plate 521 (2.5 mm × 2 = 5 mm) (L20>). L15 × 2). That is, the first hole portion 601 and the second hole portion 602 are formed at positions separated from the upper end surface 521A (the upper side of the second light guide plate 521) by at least twice the plate thickness dimension L15 of the second light guide plate 521. Yes.

  Further, the first hole portion 601 and the second hole portion 602 are not only to the upper end surface 521A (the upper side of the second light guide plate 521) but also from the periphery of the second light guide plate 521 to the plate of the second light guide plate 521. By being formed at a position more than twice the thickness L15, the strength in the vicinity of the periphery of the second light guide plate 521 is appropriately maintained so as not to be significantly reduced by the hole.

  As shown in FIG. 17, the diameter L1 of the first hole 601 is slightly longer than the diameter L2 of the first positioning boss 551 (L1> L2), but the first hole 601 has a first diameter L1. In the state in which the positioning boss 551 is inserted, there is almost no gap S1 (L1-L2) in the left-right and up-down directions between the first hole 601 and the first positioning boss 551. That is, the first positioning boss 551 is fitted into the first hole 601.

  The left and right dimension L3A of the second hole 602 is longer than the diameter L4 of the second positioning boss 552 (L3A> L4), and the vertical dimension L3B of the second hole 602 is the second positioning boss 552. The length is slightly longer than the diameter L4 (L3B> L4). Therefore, in the state where the second positioning boss 552 is inserted into the second hole 602, a left-right clearance S2 (L3A-L4) is generated between the second hole 602 and the second positioning boss 552. The vertical gap S3 (L3B-L4) hardly occurs.

  The gap S2 in the left-right direction is larger than the gap S1 (S2 (L3A-L4)> S1 (L1-L2)). Further, the gap S1 and the gap S3 are substantially the same size (S1 (L1-L2) = S3 (L3B-L4)). That is, the second hole 602 allows the second light guide plate 521 to move in the left-right direction relative to the second positioning boss 552, and does not allow movement in the up-down direction.

  As shown in FIGS. 15B, 16, and 18, the first positioning is provided at the lower position of the left oblique side of the upper end surface 511 </ b> A of the first light guide plate 511 so as to protrude from the rear left side of the middle holding member 504. A first hole 611 having a circular shape when viewed from the front is formed as a first insertion part into which the boss 571 can be inserted. In addition, a second positioning portion as a second insertion portion into which a second positioning boss 572 projecting from the rear right side of the intermediate holding member 504 can be inserted at a position below the right oblique side of the upper end surface 511A of the first light guide plate 511. Two holes 612 are formed. The 2nd hole part 612 is comprised by the elongate hole extended toward the left-right direction.

  The first hole 611 and the second hole 612 are such that a straight line LN4 passing through the centers of the first hole 611 and the second hole 612 is a straight line LN3 along the upper end surface 511A (the upper side of the first light guide plate 511). Is formed near the upper end surface 511A. Specifically, the distance L21 between the straight line LN3 and the straight line LN4 is longer than the length (2.5 mm × 2 = 5 mm) twice the thickness L15 of the second light guide plate 521 (L21>). L15 × 2). That is, the first hole portion 611 and the second hole portion 612 are formed at positions separated from the upper end surface 511A (the upper side of the first light guide plate 511) by at least twice the plate thickness dimension L15 of the first light guide plate 511. Yes.

  The first hole 611 and the second hole 612 are not only from the upper end surface 511A (the upper side of the first light guide plate 511) but also from the periphery of the first light guide plate 511 to the plate of the first light guide plate 511. By being formed at a position more than twice the thickness L15, the strength in the vicinity of the periphery of the first light guide plate 511 is appropriately maintained so as not to be significantly reduced by the hole.

  Also, a second hole 622 is formed in the lower left corner of the first light guide plate 511 as a second insertion part into which a second positioning boss 542 protruding from the right side of the rear surface of the front holding member 503 can be inserted. ing. The 2nd hole part 622 is comprised by the elongate hole extended toward the up-down direction, and is arrange | positioned in the downward position of the left end surface 511B (left side).

  As shown in FIG. 18A, the diameter L5 of the first hole 611 is slightly longer than the diameter L6 of the first positioning boss 571 (L5> L6). In the state in which the first positioning boss 571 is inserted into the first and second positioning bosses 611 and the first positioning boss 571, there is almost no left-right vertical clearance S11 (L5-L6). That is, the first positioning boss 571 is fitted into the first hole 611.

  The left and right dimension L7A of the second hole 612 is longer than the diameter L8 of the second positioning boss 572 (L7A> L8), and the vertical dimension L7B of the second hole 612 is the length of the second positioning boss 572. The length is slightly longer than the diameter L8 (L7B> L8). Therefore, in the state where the second positioning boss 572 is inserted into the second hole 612, a left-right clearance S12 (L7A-L8) is generated between the second hole 612 and the second positioning boss 572. The vertical gap S13 (L7B-L8) hardly occurs.

  The left-right clearance S12 is larger than the clearance S11 (S12 (L7A-L8)> S11 (L5-L6)). Further, the gap S11 and the gap S13 are substantially the same size (S11 (L5-L6) = S13 (L7B-L8)). In other words, the second hole 612 allows the first light guide plate 511 to move in the left-right direction with respect to the second positioning boss 572 and does not allow the vertical movement.

  As shown in FIG. 18B, the vertical dimension L7C of the second hole 622 is longer than the diameter L8 of the second positioning boss 542 (L7C> L8). The left-right dimension L7D is slightly longer than the diameter L8 of the second positioning boss 542 (L7D> L8). Therefore, when the second positioning boss 542 is inserted into the second hole 622, a vertical gap S14 (L7C-L8) is generated between the second hole 622 and the second positioning boss 542. The left-right clearance S15 (L7D-L8) is hardly generated.

  The vertical gap S14 is larger than the gap S11 (S14 (L7C-L8)> S11 (L5-L6)). Further, the gap S11 and the gap S15 are substantially the same size (S11 (L5-L6) = S15 (L7D-L8)). In other words, the second hole 612 allows the first light guide plate 511 to move in the left-right direction with respect to the second positioning boss 572 and does not allow the vertical movement.

  The diameter L2 of the first positioning boss 551 and the diameter L4 of the second positioning boss 552 are substantially the same dimension (L2 = L4). The diameter L6 of the first positioning boss 571 and the second positioning boss 572 are the same. , 542 is substantially the same size as the diameter L8 (L6 = L8). The diameters of the first positioning bosses 551 and 571 and the diameters of the second positioning bosses 572 and 542 are all the same. In this embodiment, the diameters of all the first positioning bosses 551 and 571 and the diameters of the second positioning bosses 572 and 542 are all the same, but they may be different from each other.

  A third hole 633A is formed in the upper left corner of the first light guide plate 511 as a third insertion part into which a third positioning boss 573A projecting on the left side of the back surface of the middle holding member 504 can be inserted. A third hole 633B is formed in the upper right corner of one light guide plate 511 as a third insertion part into which a third positioning boss 573B projecting from the right rear surface of the middle holding member 504 can be inserted.

  Also, a third hole serving as a third insertion portion into which the third positioning boss 543A projecting from the lower back of the side portion 503L of the front holding member 503 can be inserted in the lower left corner of the first light guide plate 511. 643A is formed, and a third positioning boss 543B projecting from the lower back of the side portion 503R of the front holding member 503 is inserted into the lower right corner of the first light guide plate 511 as a third insertion portion. The third hole 643B is formed.

  These third holes 633A, 633B, 643A, 643B are formed at positions separated from the periphery of the first light guide plate 511 by at least twice the plate thickness dimension L15 of the first light guide plate 511 (for example, the left end surface 511B). The distance L22> L15 × 2) from the center of the third hole 633A to the center of the third hole 633A is appropriately maintained so that the strength in the vicinity of the periphery of the first light guide plate 511 is not significantly reduced by the hole.

  As shown in FIGS. 19 and 20, the diameter L9 of the third holes 633A, 633B, 643A, 643B is longer than the diameter L10 of the third positioning bosses 573A, 573B, 543A, 543B ( L9> L10). Therefore, when the third positioning bosses 573A, 573B, 543A, 543B corresponding to the third holes 633A, 633B, 643A, 643B are inserted, the third holes 633A, 633B, 643A, 643B and the third positioning bosses are inserted. A gap S16 (L9-L10, about 2.2 mm) is formed in the vertical and horizontal directions between the bosses 573A, 573B, 543A, and 543B.

  The gap S16 is longer than the gaps S1 and S11 (S16 (L9-L10)> S1 (L1-L2), S11 (L5-L6), S11). In addition, the diameter L10 of the third positioning bosses 573A, 573B, 543A, 543B is longer than the diameters L2, L6 of the first positioning bosses 551, 571 (L10> L2, L6), and the second positioning bosses. The bosses 552, 572, and 542 are longer than the diameters L4 and L8 (L10> L4 and L8).

  In addition, as shown in FIG. 15, the first light guide plate 511, which is a molded product, is formed at the vicinity of the peripheral edge on the back surface of the first light guide plate 511 at the time of manufacturing the first light guide plate 511. A plurality of ejector pin traces 650 formed when being extruded and taken out from the mold. The ejector pin mark 650 is a convex portion (for example, a projecting dimension of about 0.1 mm) formed by being pressed by the ejector pin when the first light guide plate 511 is taken out of the mold, and is difficult to visually recognize unless it is watched. It is a thing of a certain degree. In particular, two portions are formed in the vicinity of each hole at the periphery of the first light guide plate 511 in order to prevent breakage during extraction.

  As shown in FIGS. 4 and 5, the light guide plate device 500 configured as described above sandwiches the second light guide plate 521 from the front side and the back side by the front holding member 503 and the middle holding member 504. While being held at the front mounting position, the first light guide plate 511 can be held at the rear mounting position by the front holding member 503, the middle holding member 504, and the rear holding member 505 so as to be sandwiched from the front side and the back side. .

  Specifically, the first hole 601 of the second light guide plate 521 is inserted into the first positioning boss 551 of the front holding member 503, and the second hole 602 of the second light guide plate 521 is inserted into the second positioning of the front holding member 503. With the second light guide plate 521 disposed on the back side of the front holding member 503, the middle holding member 504 to which the second light guide plate LED substrate 523 and the second condenser lens 524 are attached is screwed into the screw boss 552. By attaching to the front holding member 503, the front holding member 503 and the middle holding member 504 hold the second light guide plate 521 at the front attachment position so as to be sandwiched from the front side and the back side.

  The second positioning boss 552 and the second hole 602 have a gap S2 generated between the second positioning boss 552 and the second hole 602 in a state where the second light guide plate 521 is mounted at the front mounting position. The second light guide plate 521 is larger than the gap S1 generated between the first positioning boss 551 and the first hole 601 (S2> S1) and is parallel or substantially parallel to the upper end surface 521A in a specific direction (left-right direction). The movement of the second light guide plate 521 in a direction other than the left-right direction (such as the up-down direction) is restricted. As shown in FIG. 16, the second positioning boss 552 is disposed at a substantially central position in the longitudinal direction of the second hole 602.

  Next, the first hole 611 of the first light guide plate 511 is inserted into the first positioning boss 571 of the middle holding member 504, and the second hole 612 of the first light guide plate 511 is used for the second positioning of the middle holding member 504. The third hole 633A is inserted into the third positioning boss 573A of the middle holding member 504, and the third hole 633B is inserted into the third positioning boss 573B of the middle holding member 504. On the other hand, the second hole 622 of the first light guide plate 511 is inserted into the second positioning boss 542 of the front holding member 503, and the third hole 643A of the first light guide plate 511 is used for the third positioning of the front holding member 503. Inserted into the boss 543A, the third hole 643B of the first light guide plate 511 is inserted into the third positioning boss 543B of the front holding member 503.

  Then, with the first light guide plate 511 disposed on the back side of the middle holding member 504, the upper side portion 505H of the rear holding member 505 is attached to the middle holding member 504 with the screw N1, and the left and right side portions of the rear holding member 505 are attached. By attaching 505L and 505R to the front holding member 503 with the screw N2, the middle holding member 504 and the rear holding member 505 hold the first light guide plate 511 in the rear mounting position so as to be sandwiched from the front side and the back side. .

  The second positioning boss 572 and the second hole 612 have a gap S12 generated between the second positioning boss 572 and the second hole 612 in a state where the first light guide plate 511 is mounted at the rear mounting position. The first light guide plate 511 is allowed to move in a specific direction (horizontal direction) that is larger than the gap S11 generated between the first positioning boss 571 and the first hole 611 and parallel to or substantially parallel to the upper end surface 511A. On the other hand, it is provided so as to restrict the movement of the first light guide plate 511 in a direction other than the left-right direction (such as the up-down direction).

  Further, the second positioning boss 542 and the second hole 622 are gaps generated between the second positioning boss 542 and the second hole 622 in a state where the first light guide plate 511 is mounted at the rear mounting position. S14 is larger than a gap S11 generated between the first positioning boss 571 and the first hole 611 (S14> S11), and is guided in a specific direction (vertical direction) parallel to or substantially parallel to the left end surface 511B. While the movement of the light plate 511 is allowed, the movement of the first light guide plate 511 in a direction other than the vertical direction (such as the left-right direction) is regulated.

  Further, the clearance S16 between the third positioning bosses 573A, 573B, 543A, 543B and the third holes 633A, 633B, 643A, 643B is orthogonal to the axis of the third positioning boss in the first light guide plate 511. Allow movement in all directions (left / right / up / down).

  In a state where the second light guide plate 521 is held by the front holding member 503 and the middle holding member 504, the peripheral portion except the lower side portion of the second light guide plate 521 is formed by the front holding member 503 and the peripheral portion of the middle holding member 504. It is pinched from the front and back. In particular, the ridge 562F of the middle holding member 504 is disposed adjacent to the peripheral edge portion of the back surface of the second light guide plate 521 excluding the lower edge portion.

  Further, as shown in FIG. 24, the second light guide plate 521 is arranged such that the upper end surface 521A is close to the emission surface 590A of each convex portion 590 of the second condenser lens 524. That is, the upper end surface 521A is arranged so as to be parallel or substantially parallel to a straight line passing through each second light guide plate LED 522.

  On the other hand, in the state where the first light guide plate 511 is held by the front holding member 503, the middle holding member 504, and the rear holding member 505, the upper side portion of the first light guide plate 511 is the peripheral portion of the middle holding member 504 and the rear holding member 505. And sandwiched from the front and back. In particular, the ridge 562B of the middle holding member 504 is disposed close to the upper side of the front surface of the first light guide plate 511. In addition, a ridge 581 formed on the front surface of the rear holding member 505 is in contact with the back surface of the first condenser lens 514 in the left-right direction.

  As shown in FIG. 24, the first light guide plate 511 is arranged such that the upper end surface 511 </ b> A is close to the emission surface 590 </ b> A of each convex portion 590 of the first condenser lens 514. That is, the upper end surface 511 </ b> A is arranged to be parallel or substantially parallel to a straight line passing through each first light guide plate LED 512. Further, the left end surface 511 </ b> B is disposed close to the emission surface 590 </ b> A of each convex portion 590 of the first condenser lens 519. That is, the left end surface 511 </ b> B is disposed so as to be parallel or substantially parallel to a straight line passing through each first light guide plate LED 517.

  In a state where the second light guide plate 521 is held by the front holding member 503 and the middle holding member 504, a gap is provided between the second light guide plate 521 and the middle holding member 504. Further, in a state where the first light guide plate 511 is held by the middle holding member 504 and the rear holding member 505, a gap is provided between the first light guide plate 511 and the middle holding member 504.

  Specifically, for example, as shown in the enlarged view of FIG. 17, a gap S <b> 20 is provided between the protrusion 562 </ b> F of the middle holding member 504 and the back surface of the second light guide plate 521, and the protrusion 562 </ b> B of the middle holding member 504.

Further, the rear holding member 505 holds the first light guide plate 511 and the second light guide plate 521 so that a part of the periphery (upper side portion and left and right side portions) is sandwiched from the front and rear sides. The second light guide plate 521 is attached to the position, and the first light guide plate 511 is attached to the rear attachment position behind the front attachment position.

  Then, in the state where the two first light guide plates 511 and the second light guide plate 521 are held by the front holding member 503, the middle holding member 504, and the rear holding member 505 in this way, the front surface of the front second light guide plate 521. The front holding member 503 is disposed opposite to the peripheral edge (see FIG. 27A), and the middle holding member 504 is disposed opposite to the rear peripheral edge (see FIG. 27B). The middle holding member 504 is arranged to face the front peripheral edge of the first light guide plate 511 on the side (see FIG. 27C), and the rear holding member 505 is arranged to face the rear peripheral edge. (See FIG. 27D).

  In particular, the protrusions 562F of the middle holding member 504 are disposed close to the upper side and the left and right oblique sides on the back surface of the second light guide plate 521. Further, the protrusions 562B of the middle holding member 504 are disposed close to the upper side and the left and right oblique sides of the front surface of the first light guide plate 511, and the rear holding member 505 is provided to the upper side and the left and right sides of the rear surface. The protrusions 549A of the uneven portions 549L and 549R are arranged close to each other. These ridges 562F and 562B and the convex portions 549A of the concave and convex portions 549L and 549R function as a holding portion of the holding body.

  In this embodiment, the front and rear surfaces of the first light guide plate 511 and the second light guide plate 521 are held by the front holding member 503, the middle holding member 504, and the rear holding member 505, while the first positioning boss 571, 551, second positioning bosses 572, 552, 542 and third positioning bosses 573A, 573B, 543A, 543B are first hole portions 601, 611, second hole portions 602, 612, 622, third hole portion 633A, The insertion positions of the first light guide plate 511 and the second light guide plate 521 with respect to the holding body are determined by inserting them into 633B, 643A, and 643B, respectively, and a downward deviation from the holding body is prevented.

  Next, thermal expansion of the first light guide plate 511 and the second light guide plate 521 will be described with reference to FIGS. 22 and 23.

  Since the first light guide plate 511 and the second light guide plate 521 are made of a transparent plate with an acrylic resin material having a thickness L15 of about 2.5 mm, as described above, according to the temperature change inside the pachinko gaming machine 1 Stretching occurs.

  In the present embodiment, for example, as shown in FIG. 23, the separation dimension L40 between the first hole 611 and the third hole 643B in the first light guide plate 511 is about 442 mm. Becomes about ± 0.6 mm, and an elongation of about 1.6 mm at maximum occurs with respect to a temperature change of 40 degrees. Therefore, if the positions of the first hole 611 and the third hole 643B are fixed, an irreversible warpage of about 16.3 mm may occur due to a temperature change.

  First, the second light guide plate 521 will be described. As shown in FIG. 22A, in the state where the second light guide plate 521 is held by the front holding member 503 and the middle holding member 504, The first positioning boss 551 is fitted, and the second positioning boss 552 is inserted at a substantially central position in the left-right direction of the second hole 602.

  As shown in FIG. 22B, when the second light guide plate 521 thermally expands, the second light guide plate 521 moves relative to the front holding member 503 and the middle holding member 504. By fitting the part 601 to the first positioning boss 551 formed on the front holding member 503, the part 601 extends radially (in the direction of the arrow in the figure) with the first hole 601 as a reference.

  Here, the first hole 601 and the second hole 602 are provided in the vicinity of the upper end surface 521A where the light emitted from the emission surface 590A of the second condenser lens 524 is incident, Since the vertical gap S1 with the positioning boss 551 and the vertical gap S3 with the second positioning boss 552 are small, the width of the upward extension from the first hole 601 and the second hole 602 is kept small. be able to. Therefore, the upper end surface 521A of the second light guide plate 521 extends toward the upper second condenser lens 524, so that the distance from the second condenser lens 524 is one position in the left-right direction (for example, the right position). And the other position (for example, the left position), that is, the positional relationship between the emission surface 590A of the second condenser lens 524 and the upper end surface 521A is shifted, or the upper end surface 521A is the second condenser. It is possible to prevent the second condenser lens 524 from being damaged or damaged by coming into contact with the lens 524 or the like.

  On the other hand, since the gap S2 between the second positioning boss 552 and the second hole 602 is larger than the gap S1, the leftward extension with respect to the first hole 601 is allowed, so FIG. B), the second positioning boss 552 for positioning the second light guide plate 521 at the front mounting position is provided even when the second hole 602 is greatly displaced to the left with respect to the second positioning boss 552. Since the pressing and folding can be avoided, it is possible to prevent the positional deviation with respect to the front holding member 503 and the middle holding member 504 from adversely affecting the incidence of light from the second condenser lens 524 to the upper end surface 521A.

  Since the second light guide plate 521 has no positioning hole other than the first hole 601 and the second hole 602 on the upper side, the second light guide plate 521 extends downward with the first hole 601 as a reference. Will be allowed.

  Next, the first light guide plate 511 will be described. In the state where the first light guide plate 511 is held by the front holding member 503, the middle holding member 504, and the rear holding member 505, as shown in FIG. A first positioning boss 571 is fitted into the hole 611, a second positioning boss 572 is inserted at a substantially central position in the left-right direction of the second hole 612, and the second hole 622 is approximately in the vertical direction. A second positioning boss 542 is inserted at the center position. In addition, third positioning bosses 573A and 573B are provided at substantially central positions of the third hole portions 633A and 633B so that the axial center is located at the center of the third hole portions 633A and 633B. Third positioning bosses 543A and 543B are provided at substantially the center positions of 643A and 643B so that the shaft center is located at the center of the third hole portions 643A and 643B.

  As shown in FIG. 23B, when the first light guide plate 511 thermally expands, the first light guide plate 511 moves relative to the front holding member 503, the middle holding member 504, and the rear holding member 505. However, when the first hole 611 is fitted to the first positioning boss 571 formed in the intermediate holding member 504, the first hole 611 extends radially (in the direction of the arrow in the figure) with the first hole 611 as a reference. become.

  Here, the first hole portion 611 and the second hole portion 612 are provided in the vicinity of the upper end surface 511A on which the light emitted from the emission surface 590A of the first condenser lens 514 is incident, Since the vertical gap S11 between the hole 601 and the first positioning boss 571 and the vertical gap S13 between the second hole 602 and the second positioning boss 572 are small, the first hole 611 and the second hole It is possible to keep the extension width upward from the portion 612 small. Therefore, when the upper end surface 511A of the first light guide plate 511 extends toward the upper first condenser lens 514, the distance from the first condenser lens 514 is one position in the left-right direction (for example, the right position). And the other position (for example, the left position), that is, the positional relationship between the emission surface 590A and the upper end surface 511A of the first condenser lens 514 is shifted, or the upper end surface 511A is the first condenser. The first condensing lens 514 is prevented from being damaged or damaged by contacting the lens 514 or the like.

  On the other hand, since the gap S12 between the second positioning boss 572 and the second hole 612 is larger than the gap S11, the rightward extension with respect to the first hole 611 is allowed, so FIG. As shown in B), even when the second hole 612 is greatly displaced to the right with respect to the second positioning boss 572, the second positioning boss 572 for positioning the first light guide plate 511 at the rear mounting position is provided. Since it is possible to avoid pressing and folding, the positional deviation with respect to the front holding member 503, the middle holding member 504, and the rear holding member 505 adversely affects the incidence of light from the first condenser lens 514 to the upper end surface 511A. Can be prevented.

  The first hole 611 and the second hole 622 are provided in the vicinity of the left end surface 511B where the light emitted from the emission surface 590A of the first condenser lens 519 is incident, and the first hole Since the horizontal gap S11 between the portion 611 and the first positioning boss 571 and the horizontal gap S15 between the second hole 612 and the second positioning boss 542 are small, the first hole 611 and the second hole The extension width from 622 to the left can be kept small. Therefore, the left end surface 511B of the first light guide plate 511 extends toward the left first condenser lens 519, so that the distance from the first condenser lens 519 is one position in the vertical direction (for example, the upper position). ) And other positions (for example, the lower position), that is, the positional relationship between the emission surface 590A of the first condenser lens 519 and the left end surface 511B is shifted, or the left end surface 511B is the first position. It is possible to prevent the first condenser lens 519 from being damaged or damaged by coming into contact with the condenser lens 519 or the like.

  On the other hand, since the gap S14 between the second positioning boss 542 and the second hole 622 is larger than the gap S11, the downward extension with respect to the first hole 611 is allowed, so FIG. As shown in B), the second positioning boss 542 for positioning the first light guide plate 511 at the rear mounting position even when the second hole 622 is greatly displaced downward with respect to the second positioning boss 572. Can be avoided from being pressed, so that the positional deviation with respect to the front holding member 503, the middle holding member 504, and the rear holding member 505 adversely affects the incidence of light from the first condenser lens 519 to the left end surface 511B. Can be prevented.

  Further, a gap S16 between the third hole portions 633A, 633B, 643A, 643B formed at the four corners of the first light guide plate 511 and the third positioning bosses 573A, 573B, 543A, 543B is formed with the first hole portion 611. Since it is larger than the gap S11 with the first positioning boss 571, it is allowed to extend in the front-rear and left-right directions (omnidirectional) with reference to the first hole 611, as shown in FIG. Even if each of the third hole portions 633A, 633B, 643A, 643B is greatly displaced in any direction with respect to each of the third positioning bosses 573A, 573B, 543A, 543B, the first light guide plate 511 is positioned at the rear mounting position. For this reason, it is possible to avoid pressing and folding the third positioning bosses 573A, 573B, 543A, and 543B. The positional deviation for beauty after holding member 505 can prevent the adverse effects from the first condenser lens 514,519 to incidence of light to the upper end face 511A and the left end surface 511B.

  In FIGS. 22 and 23, the case where the first light guide plate 511 and the second light guide plate 521 are thermally expanded has been described. For example, pachinko games during manufacturing in winter, storage, non-business at a game hall, etc. When the first light guide plate 511 and the second light guide plate 521 contract due to a decrease in the internal temperature of the machine 1, although not particularly illustrated, the first light guides 601 and 611 contract radially, that is, The peripheral portions of the first light guide plate 511 and the second light guide plate 521 contract so as to move toward the first hole portions 601 and 611.

  Even in such a case, the second positioning bosses 552, 572, and 542 are inserted at substantially the center positions in the longitudinal direction of the second holes 602, 612, and 622, and the third holes 633A and 633B are substantially omitted. Third positioning bosses 573A and 573B are provided at the center position so that the shaft centers are located at the centers of the third hole portions 633A and 633B, and the third hole portions 633A and 643B are substantially The third positioning bosses 543A and 543B are provided so that the axial center is located at the center of the third hole portions 643A and 643B, so that the second positioning bosses 552, 572 and 542 and the third positioning bosses 573A and 573B are provided. , 543A, 543B, the second holes 602, 612, 622 and the third holes 633A, 633B, 643A, 643B move toward the first holes 601, 611. Since the volumes of the second positioning boss 552,572,542 and the third positioning bosses 573A, 573B, 543A, breakage of 543B can be prevented.

  Next, the effect display mode by the light guide plate device 500 will be described with reference to FIGS. FIGS. 24A and 24B are explanatory diagrams showing a second effect display mode and FIG. 24B showing a first effect display mode. 25A is a diagram showing a light guide mode of the LED, the condensing lens, and the light guide plate, and FIG. 25B is an LL cross-sectional view of FIG. 24A.

  As shown in FIGS. 24A and 25, when the second light guide plate LED 522 is turned on, the light from the second light guide plate LED 522 is incident on the incident surface 591A of the second condenser lens 524, and the second condenser lens. The light is guided while being reflected inside 524, is emitted from the emission surface 590 </ b> A, and is incident on the upper end surface 521 </ b> A of the second light guide plate 521. Then, the light incident from the upper end surface 521A is guided while being reflected inside, and reflected forward by the reflecting portion 596, so that when the second light guide plate 521 is viewed from the front, the second light guide plate 521 is viewed from the front. When the region corresponding to the reflecting portion 596 in the light guide plate 521 emits light, the second effect display in which the characters “Intense heat!” Is displayed and emitted is performed.

  When the first light guide plate LED 512 is turned on, the light from the first light guide plate LED 512 is incident on the incident surface 591A of the first condenser lens 514 and is guided while being reflected from the inside of the first condenser lens 514. The light is emitted from the emission surface 590 </ b> A and is incident on the upper end surface 511 </ b> A of the first light guide plate 511. Then, the light incident from the upper end surface 511A is guided while being reflected inside, and is reflected forward by the reflecting portion 598, so that the first light guide plate 511 is viewed from the front when the first light guide plate 511 is viewed from the front. When the region corresponding to the reflective portion 598 in the light guide plate 511 emits light, the second effect display in which the characters “Intense heat!” Is emitted and displayed is performed. Note that when the movable body 301 is located at the standby position, the letters “extremely hot!” Are displayed on the front side of the movable body 301 in a light-emitting manner.

  In addition, when the first light guide plate LED 512 and the second light guide plate LED 522 are turned on at the same time, the characters “Intense heat!” Are superimposed on the front and rear of both the second light guide plate 521 and the first light guide plate 511. Is done.

  On the other hand, when the left first light guide plate LED 517 is turned on, the light from the first light guide plate LED 517 is incident on the incident surface 591A of the first condenser lens 519, and is guided while reflecting the inside of the first condenser lens 519. Then, the light is emitted from the emission surface 590 </ b> A and is incident on the left end surface 511 </ b> B of the first light guide plate 511. Then, the light incident from the left end surface 511B is guided while being reflected inside, and reflected forward by the reflecting portion 598, so that when the first light guide plate 511 is viewed from the front, the first When the region corresponding to the reflection portion 598 in the light guide plate 511 emits light, the first effect display in which the effect is displayed by light emission is performed. When the movable body 301 is located at the effect position, the effect is displayed by light emission around the movable body 301.

  In the present embodiment, the effect control CPU 120 is capable of executing a second effect display that emits and displays the characters “Intense heat!” As a jackpot notice effect that suggests the possibility of a big hit. In other words, this second effect display is a character that suggests that the player has a high probability of winning a big hit, and a suitable light-emitting display is not performed due to the thermal expansion of the first light guide plate 511 or the second light guide plate 521, so that the player If the character cannot be recognized, it will not make sense as a notice effect. Therefore, the effect that is more important than the first effect display in which the effect of decorating the periphery of the movable body 301 that has just moved to the effect position is displayed. It is said that. Specifically, as described above, the first light guide plate 511 and the second light guide plate 521 are thermally expanded, so that the positional relationship between the emission surface 590A and the upper end surfaces 511A and 521A is shifted, or the second condenser lens 524 is used. If the first condensing lens 514 is damaged and the characters “Intense heat!” Cannot be displayed in a light-emitting manner in a manner that the player can recognize, the possibility of a big hit cannot be suggested. As a result, the player's expectation may not be improved appropriately.

  On the other hand, with respect to the effects, the first light guide plate 511 is thermally expanded, so that the positional relationship between the emission surface 590A and the left end surface 511B is shifted, or the first condenser lens 519 is damaged. However, if it becomes impossible to perform light emission display in a recognizable manner, the decorativeness is reduced, but the possibility of a big hit cannot be suggested.

  Therefore, in the present embodiment, for the portions corresponding to the first light guide plate LED 512 and the second light guide plate LED 522 that emit light when executing the second effect display having higher importance than the first effect display, the first light guide plate The first light guide plate 511 and the second light guide plate so that the positional relationship between the second condenser lens 524 and the first condenser lens 514 and the upper end surfaces 511A and 521A does not change due to thermal expansion of the 511 and the second light guide plate 521. In 521, the first hole portions 601 and 611 and the second hole portions 602 and 612 are provided such that the straight lines LN2 and LN4 are parallel to the straight lines LN1 and LN3 along the upper end surfaces 511A and 521A. .

  In this embodiment, the second hole 622 is not provided so that the straight line passing through the first hole 611 and the second hole 622 is parallel to the straight line along the left end surface 511B.

  By doing so, the first light guide plate 511 and the second light guide plate 521 are prevented from coming off from between the third positioning bosses 573A, 573B, 543A, 543B and the rear holding member 505, and the first guide It is possible to suitably cope with the thermal expansion of the light plate 511 and the second light guide plate 521.

  In addition, uneven portions 549L and 549R are provided in the front holding member 503 at positions facing the first light guide plate 511, and the first light guide plate 511 is held by the front holding member 503, the middle holding member 504, and the rear holding member 505. In FIG. 8, a gap S22 is provided between the convex portions 549A and the first light guide plate 511 in the concave and convex portions 549L and 549R (FIG. 8B).

  By doing in this way, it can respond suitably with respect to the thermal expansion of the 1st light guide plate 511 (a clearance gap larger than the clearance gap provided between a convex part between a light guide plate and a recessed part arises). Specifically, the front holding member 503, the middle holding member 504, and the rear holding member 505 are structures that hold the peripheral portions of the first light guide plate 511 and the second light guide plate 521 so as to be sandwiched from the front side and the back side. By providing the concavo-convex portions 549L and 549R, the contact area with the first light guide plate 511 can be minimized (partially brought into contact).

However, by providing the uneven portions 549L and 549R, the contact area with the first light guide plate 511 can be minimized (partially brought into contact). Further, the ejector pin marks 650 (convex portions) formed on the front surface and the rear surface of the first light guide plate 511 and the second light guide plate 521 do not face the uneven portions 549L and 549R, so that the first light guide plate 511 and the Since it can avoid that the 2nd light guide plate 521 expands and contracts, and the ejector pin trace 650 contacts uneven | corrugated | grooved part 549L, 549R, it can respond suitably with respect to the thermal expansion of the 1st light guide plate 511 or the 2nd light guide plate 521.

  Further, in a state where the first light guide plate 511 is held by the front holding member 503, the middle holding member 504, and the rear holding member 505, a gap (for example, a gap S22) is provided between the first light guide plate 511 and the convex portion 549A. (FIG. 8B).

  Thus, by providing the clearance S22 (clearance) between the first light guide plate 511 and the second light guide plate 521, it is preferable to avoid the occurrence of warpage due to the absence of escape from thermal expansion. Therefore, it is possible to suitably cope with the thermal expansion of the first light guide plate 511.

  Further, in the pachinko gaming machine 1 as an embodiment of the present invention, the first light guide plate LEDs 512 and 517 and the second light guide plate LED 522 as light emitting means, and light enters from the upper end surfaces 511A and 521A and the left end surface 511B. In this way, the first light guide plate 511 and the second light guide plate 521 capable of effect display (light emission display), and the light incident from the light emitting means are applied to the first light guide plate 511 and the second light guide plate 521. First condensing lenses 514 and 519 and second condensing lens 524 as light guide members that are emitted toward, and attached portions to which first condensing lenses 514 and 519 and second condensing lens 524 are attached (for example, The back surface of the front holding member 503, the back surface of the first light guide plate LED substrate 513, the front surface of the second light guide plate LED substrate 523, the front surface of the rear holding member 505, the back surface of the first light guide plate LED substrate 518L), The first condenser lenses 514 and 519 and the second condenser lens 524 are provided with positioning holes 530 and 594 as positioning portions provided in the attached portion in a state of being attached to the attached portion, and positioning holes 595. , 580 and condensing lens positioning bosses 593F and 593B that can be inserted into the positioning hole 595A.

  In this way, the condensing lens positioning bosses 593F and 593B are inserted into the positioning holes 530 and 594, the positioning holes 595 and 580, and the positioning hole 595A, so that the first condensing lenses 514 and 519 and the second condensing lenses are collected. Since the attachment position of the lens 524 is determined, the first condenser lens 514 and the second condenser lens 524 can be suitably attached.

  Further, the condensing lens positioning bosses 593F and 593B of the first condensing lenses 514 and 519 and the second condensing lens 524 are provided with the first light guide plate LEDs 512 and 517 and the second light guide plate LED 522, respectively. By being inserted into the positioning holes 594, 595, 595A provided in the light plate LED substrate 513, 518L and the second light guide plate LED substrate 523, the positioning is accurately performed with respect to the first light guide plate LEDs 512, 517 and the second light guide plate LED 522. Therefore, the light from the first light guide plate LEDs 512 and 517 and the second light guide plate LED 522 can be preferably incident.

  The condensing lens positioning bosses 593F and 593B are provided so as to protrude from the surface of the light exit surface 590A and the surface orthogonal to the incident surface 591A, thereby reflecting the light incident on the inside. It is difficult to influence (see FIG. 14).

  By doing in this way, the 1st condensing lens 514 and the 2nd condensing lens 524 can be attached suitably.

  The holding body includes a front holding member 503, a middle holding member 504, and a rear holding member 505. The holding body includes a first light guide plate 511 and a second light guide plate 521, the front holding member 503, and the middle holding member 504. In a state of being held by the rear holding member 505, lens hooks 531 and 564 and convex ridges 581 are provided as restricting portions that restrict movement of the first condenser lens 514 and the second condenser lens 524.

  By doing in this way, the 1st condensing lens 514 and the 2nd condensing lens 524 can be attached suitably. In addition, the holding pieces 592A and 592B that are locked by the lens hooks 531 and 564 and the protrusion 581 are formed on the left and right ends of the first condenser lens 514 and the second condenser lens 524, and therefore are guided. It can be installed so that the light is not affected as much as possible.

  In this embodiment, the light from the first light guide plate LEDs 512 and 517 and the second light guide plate LED 522 passes through the first light collecting lenses 514 and 519 and the second light collecting lens 524, and then the first light guide plate 511 and the second light guide plate 522. The first condensing lenses 514 and 519 and the second condensing lens 524 and the first light guiding plate 511 and the second light guiding plate 521 are made of the same material (for example, an acrylic resin material). However, the present invention is not limited to this. For example, the condenser lens may be made of a material different from that of the light guide plate. Specifically, the light from the LED can be suitably guided to the light guide plate by being made of a material that is less likely to be deformed by heat than the light guide plate. Further, even if the material is not different, it may be difficult to be deformed by reducing the volume or increasing the thickness of the light guide plate.

  Also, the first condenser lenses 514 and 519 and the second condenser lens 524 are interposed between the first light guide plates LED 512 and 517 and the second light guide plate LED 522 and the first light guide plate 511 and the second light guide plate 521. Therefore, since heat from the first light guide plate LEDs 512 and 517 and the second light guide plate LED 522 is hardly transmitted to the first light guide plate 511 and the second light guide plate 521, thermal expansion can be suppressed.

  Further, the front holding member 503, the middle holding member 504, and the rear holding member 505 as the holding body on which the positioning boss is formed are preferably made of a material that is not easily deformed by a temperature change as compared with the light guide plate. The first light guide plate 511 and the second light guide plate 521 may be made of the same material. By doing in this way, since a light-guide plate and a holding body expand / shrink similarly by a temperature change, it can respond suitably to thermal expansion.

  In the present embodiment, the effects by the light guide plates such as the first light guide plate and the second light guide plate can be executed at a plurality of timings. Furthermore, the degree of expectation can be varied depending on the timing at which the effect by the light guide plate is executed. If the player's attention can be gathered at the execution timing of the effect by the light guide plate, the effect effect of the effect by the light guide plate can be improved, and the interest based on the effect by the light guide plate can be further improved.

  The execution timing of the effect by the light guide plate is not particularly limited. For example, when 1 variable display is started, before the reach state is generated in 1 variable display, when the reach state is generated in 1 variable display, After the reach state is generated in the variable display of 1, the game state is such as a big hit gaming state. In addition, the timing at which various effects other than the effects by the light guide plate are executed can also be mentioned. More specifically, the execution timing of the effect by the light guide plate includes the timing at which the movable body effect by the movable body 301 of the effect unit 300 is executed, the timing at which the player operates the stick controller 31A or the push button 31B, and the like. Can be mentioned. In one variation display, the effect by the light guide plate may be executed a plurality of times.

  The execution timing of the effect by the light guide plate in the big hit gaming state is not particularly limited, but for example, when the production showing that the type of big hit that shifts to the high probability state is executed, the round continues. For example, when the effect to be shown is executed, the effect to indicate that the hold memory that is a big hit is stored is stored. In addition, in the case of a gaming machine of the type that shifts to a certain change state based on the passing of a game ball in a specific area, there is a time when an effect indicating that the game ball has passed in the specific area is executed.

  In addition, the effect by the light guide plate is, for example, a period during which a specific gaming state (for example, high base state, low base state, high probability state, low probability state) is controlled or a specific effect mode (for example, high It may be possible to execute at a predetermined timing in a period controlled by a latent mode or a mission mode that makes it difficult for the player to recognize whether or not the player is in a probability state. Moreover, it is good also as execution as an effect with respect to the fluctuation | variation which has not started yet (so-called prefetching effect).

  Further, when the gaming machine includes two or more light guide plates, the execution timing of the effects by the light guide plates may be different depending on the light guide plates. Further, the execution timing of the effects by the light guide plate in the plurality of light guide plates may be simultaneous. For example, the effect by the first light guide plate may be executed, and then the effect by the second light guide plate may be executed, or the effect by the first light guide plate and the effect by the second light guide plate may be executed simultaneously. As a more specific example, an effect by the first light guide plate is executed before the reach state occurs in one variable display, and an effect by the second light guide plate is generated when the reach state occurs or after the reach state occurs. Such as being executed.

  The effect by the light guide plate may be executable in parallel with the effect other than the effect by the light guide plate. In addition, when an effect other than the effect by the light guide plate is being executed, the execution of the effect by the light guide plate may be limited.

  Further, in the effect by the light guide plate, the degree of expectation can be varied depending on the timing at which the effect is executed. For example, as the timing at which an effect by the light guide plate is executed in one variation display, when one variation display starts, when a reach state occurs in one variation display, after a reach state occurs in one variation display When the effect by the light guide plate is executed once in one variation display, the degree of expectation increases as the timing at which the effect by the light guide plate is executed in one variation display becomes later, Can be lowered.

  Further, when the gaming machine includes two or more light guide plates, the degree of expectation can be varied depending on the timing at which the effect by the light guide plate is executed and the light guide plate at which the effect by the light guide plate is executed. For example, as the timing at which an effect by the light guide plate is executed in one variation display, when one variation display starts, when a reach state occurs in one variation display, after a reach state occurs in one variation display The first light guide plate and the second light guide plate are provided as the light guide plates, and the effect by the second light guide plate is higher than the effect by the first light guide plate. When the effect by the first light guide plate or the effect by the second light guide plate is executed once, the expectation is increased as the timing at which the effect by the light guide plate is executed in the variation display of 1, and the expectation is increased. The degree of expectation can be made higher when the effect by the second light guide plate is executed than when the effect is executed. Therefore, in such a case, when the effect by the second light guide plate is executed after the reach state is generated in one variation display, the effect is the most expected. Thus, by gathering the player's attention on the execution timing of the effect by the light guide plate and which light guide plate the effect by the light guide plate is executed, the effect effect of the effect by the light guide plate can be further improved. The interest based on the production by can be further improved.

  Note that the “expectation degree” refers to an expectation degree that the gaming machine is controlled to be in an advantageous state for an advantageous person. For example, in the above gaming machine, when an effect by a light guide plate is executed in one variation display, an expectation level for a big hit gaming state, an expectation level for a transition to an effect with a high probability of a big hit (so-called super reach effect), etc. Can increase the degree of expectation. In addition, when the effect by the light guide plate is executed during the jackpot gaming state, the degree of expectation for the transition to the high probability state, the degree of expectation for the continuation of the round, the degree of expectation that the reserved memory that is the jackpot is stored, etc. Can increase the degree of expectation.
