As an example, in the effect control board 12, the effect control CPU 120 executes the effect control program read from the ROM 121, thereby executing the process for controlling the effect operation by the effect electric components. Further, in the ROM 121, in addition to the effect control program, various data tables and the like used for controlling the effect operation are stored.

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 gaming ball has passed through the passing gate 41 provided in the gaming area 10, the normal symbol game by the normal symbol display 20 is started. After starting the fluctuation of the normal symbol, if the predetermined time that is the normal symbol fluctuation time elapses and the normal symbol other than the normal symbol per symbol is stopped and displayed, the fluctuation display result of the normal symbol is "out of normal symbol". Become. If a specific normal symbol (design per normal symbol) is stopped and displayed, the variable display result of the normal symbol becomes "per normal symbol", and the open control for retracting the movable plate of the normal variable winning ball device 6B from the game area 10 is performed. Then, when a predetermined time elapses, the normal opening control for returning to the closed position protruding into the game area 10 is performed.

Based on the fact that the first start condition is satisfied, for example, due to the end of the previous special figure game or the jackpot game state, after the first start condition is satisfied due to the game ball winning the first start winning opening. , The special symbol game by the first special symbol display 4A is started. In addition, after the second start condition is satisfied due to the game ball winning the second start winning opening, for example, the second start condition is satisfied due to the end of the previous special figure game or the jackpot game state. Based on this, the special symbol game by the second special symbol display 4B is started.

In the special symbol game, after the variable display of the special symbol is started, the confirmed special symbol (special symbol display result) is derived and displayed when the variable display time elapses. At this time, if a specific special symbol (big hit symbol) is stopped and displayed, it becomes a "big hit" as a specific display result, and if a special symbol different from the big hit symbol is stopped and displayed, it becomes "missing". After the variable display result in the special figure game becomes a "big hit", the game is controlled to a big hit game state as a specific game state in which a round (also referred to as a "round game") advantageous to the player is executed a predetermined number of times.

In the big hit game state, the big winning door of the special variable winning ball device 7 is a period until a predetermined upper limit time (for example, 29 seconds or 0.1 seconds) elapses or a predetermined number (for example, 9) of winning balls. The big prize opening will be open until the occurrence of. As a result, a round is executed in which the special variable winning ball device 7 is set to the first state (open state) which is advantageous for the player.

The large winning opening door that opens the large winning opening during the execution of the round catches the game ball falling on the surface of the game board 2, and then closes the large winning opening, thereby causing a special variable winning ball device. 7 is changed to a second state (closed state) which is disadvantageous to the player, and one round is completed. The round, which is the opening cycle of the big winning opening, can be repeatedly executed until the number of executions reaches a predetermined upper limit (for example, "16").

In the effect symbol display areas 5L, 5C, and 5R of the effect display device 5, the variable display of the effect symbol is started in response to the start of the special figure game. Then, in the period from the start of the variable display of the effect symbol to the end of the variable display, the variable display state of the effect symbol may be in a predetermined reach state. The reach state is a display in which the effect symbols that have been stopped and displayed in the display area of the effect display device 5 constitute a part of the jackpot combination, and the effect symbols that have not yet been stopped and displayed continue to fluctuate. It is a state, or a display state in which all or part of the effect symbols are synchronously fluctuating while forming all or part of the jackpot combination.

As a definite special symbol in the special symbol game, among a plurality of types of jackpot combinations, a definite effect symbol that is a predetermined normal jackpot combination (also referred to as "non-probability variable jackpot combination") is stopped and displayed, and the variable display result is "non-probable variable jackpot". If it becomes, the jackpot state is controlled, and after the end, the time reduction control (time reduction control) is performed. By performing the time reduction control, the fluctuation display time (special figure fluctuation time) of the special symbol in the special figure game is shortened as compared with the normal state. In the time saving control, so-called electric chew support is implemented in which the winning frequency of the normal symbol is increased and the winning frequency of the normal variable winning ball device 6B is increased. In the time saving control, one of the conditions that the special figure game is executed a predetermined number of times (for example, 100 times) after the end of the big hit game state and that the variable display result becomes "big hit" is satisfied first. Sometimes you just have to quit.

As a definite special symbol in the special figure game, among a plurality of types of jackpot combinations, a definite effect symbol that is a predetermined probability variation jackpot combination (also referred to as "probability variation jackpot combination") is stopped and displayed, and the variable display result is "probability variation jackpot". If it becomes a big hit, it is controlled to a big hit state, and after the end, probability fluctuation control (probability variation control) is performed together with time reduction control. By performing this probability variation control, the probability that the variation display result becomes a "big hit" in each special figure game is improved so as to be higher than in the normal state. In the probability variation control, when the condition that the fluctuation display result becomes "big hit" and the game is controlled to the big hit game state again after the end of the big hit game state is satisfied, a predetermined number of times (for example, 100, which is the same as the time reduction number) after the end of the big hit game state is satisfied. When the special figure game of (times) is executed, it is decided that "there is a probability change fall" to end the probability change control by the probability change fall lottery that is executed every time the special figure game is started after the end of the jackpot game state. When, etc., it should end.

When the time reduction control is performed, the fluctuation time of the normal symbol (normal symbol fluctuation time) in the normal diagram game is made shorter than that in the normal state, and the variation display result of the normal symbol in each normal diagram game is "normal diagram". The control to improve the probability of "hit" compared to the normal state, and the movement control time to control the movement of the movable plate in the normal variable winning ball device 6B based on the fact that the variation display result is "hit" is usually set. There is a possibility that the second starting condition will be satisfied by making it easier for the game ball to pass (enter) the second starting winning opening, such as control to make it longer than in the state and control to increase the number of movements compared to the normal state. Controls (electric chew support control, high open control) that are advantageous to the player are performed by increasing the value. This makes it easier to establish the second start condition for executing the special figure game using the second special figure, and the special figure game can be executed frequently, so that the variable display result is "big hit" next. The time until becomes is shortened.

Further, in the first condenser lens 519, the front condenser lens positioning boss 593F is inserted into the 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 the positioning hole 530 formed in the front holding member 503 (see FIG. 6), and the rear condenser lens positioning boss 593B is rearward. It is inserted into a positioning hole 595 (see FIG. 9) formed in the holding member 505.

The condensing lens positioning bosses 593F and 593B correspond to the convex portions 590 and 591 of one of the plurality formed on the first condensing lens 514, the second condensing lens 524 and the first condensing lens 519, respectively. Positioning accuracy is high because the lens is projected at the position where the width dimension (vertical width dimension or horizontal width dimension) is the longest, that is, the position where the strength is higher than the position where the width dimension is short. improves. Further, the front and rear surfaces of the first condensing lens 514, the second condensing lens 524, and the first condensing lens 519, that is, positions other than the light emitting surface 590A and the incident surface 591A, specifically, the light emitting surface 590A. And because it is provided so as to project on the surface of the surface orthogonal to the incident surface 591A, it does not affect the incident or emitted light. Further, the front and rear condensing 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 composed of a flat surface extending in the left-right direction. The left and right hypotenuses and side sides are formed along the front holding member 503 and the middle holding member 504, and the lower side portion is along 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 reflecting portion 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. 24 (B)). The reflection unit 596 is arranged in such a manner that the characters "extreme heat!" Can be emitted and displayed.

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 composed of a flat surface extending in the left-right direction, the left end surface 511B is composed of 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 shape is such that 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, there is a reflecting portion 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 reflecting portion 597B and the reflecting portion 597B of the above are formed respectively (see FIG. 24 (B)). The reflection unit 597A is arranged in a manner capable of displaying the characters "super heat!" By emitting light, and the reflection unit 597B emits an effect of decorating the surroundings of the movable body 301 when the movable body 301 moves to the effect position. It is arranged in a displayable manner. The reflection unit 597A is configured to be capable of displaying characters similar to the reflection unit 596 of the second light guide plate LED 522, and is a front holding member so as to superimpose the first light guide plate 511 and the second light guide plate 521 on the front and back. It is arranged on the first light guide plate 511 so as to be superimposed on the back surface side of the reflecting portion 596 in a state of being held by the middle holding member 504 and the rear holding member 505 and held at a predetermined mounting position.

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

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

Further, only the light from the first light guide plate LED 512 is reflected forward by the reflection unit 597A and the characters "extreme heat!" Are emitted and displayed, and only the light from the first light guide plate LED 517 is forward by the reflection unit 597B. The details of the light guide structure in which the effect is emitted and displayed by reflecting on the light guide structure will be omitted. In this embodiment, only the light from the first light guide plate LED 512 is reflected by the reflection unit 597A, and only the light from the first light guide plate LED 517 is reflected by the reflection unit 597B. The light from the LED 512 or the light from the first light guide plate LED 517 may be reflected by both the reflecting portions 597A and 597B to display light emission.

Further, in this embodiment, characters and patterns are exemplified as display information that can be displayed by the first light guide plate 511 and the second light guide plate 521, but in addition to these, decorations such as symbols, patterns, or patterns are used. Other display information including the above may be displayable. Further, the first light guide plate 511 and the second light guide plate 521 do not necessarily have to be transparent as long as they have translucency, and may be, for example, colored or translucent.

The first light guide plate 511 and the second light guide plate 521 are made of a transparent plate having a thickness dimension L15 of about 2.5 mm made of an acrylic resin material, and are plate surface plates made of a transparent synthetic resin material constituting the game board 2. Since it is thinner than the thick 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 in a state of being assembled to 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 inside closed by the glass door frame 50 and the cover body. The space is provided with a large 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 of the pachinko gaming machine 1 during operation is higher than that during non-operation, 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, A temperature change of about 40 degrees causes expansion and contraction of up to about 1.6 mm.

Specifically, for example, in the case of the first light guide plate 511, the warp tolerance (flatness intersection) is about 3 to 6 mm. Therefore, for example, when the light guide plate device 500 is attached to the back surface of the game board 2. The distance from the second light guide plate 521 on the front side and the distance from the effect display device 5 and other members on the rear side are preferably more 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 in a state where a part of the peripheral edge thereof is sandwiched from the front and back by the front holding member 503, the middle holding member 504, and the rear holding member 505. Since the structure is 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 may be damaged or damaged due to assembly distortion due to manufacturing dimensional tolerances or assembly errors. In addition to the above-mentioned expansion and contraction due to temperature changes, there is a risk of contact with the front holding member 503, the middle holding member 504, and the rear holding member 505, resulting in damage or damage.

Therefore, as described below, the light guide plate device 500 of this embodiment is the first light guide plate 511 so as to be able to cope with the temperature change inside the pachinko gaming machine 1, the dimensional tolerance in manufacturing, and the assembly error. The second light guide plate 521 is attached to each of the front holding member 503, the middle holding member 504, and the rear holding member 505 with a predetermined gap (clearance).

As shown in FIGS. 15A, 16 and 17, the first positioning boss 551 projecting from the left side of the back surface of the front holding member 503 is located at the lower right position of the upper end surface 521A of the second light guide plate 521. A front-view circular first hole portion 601 is formed as a first insertion portion into which the can be inserted. Further, at the lower left position of the upper end surface 521A of the second light guide plate 521, a front view horizontally long shape as a second insertion portion into which a second positioning boss 552 projecting from the right side of the back surface of the front holding member 503 can be inserted. The second hole portion 602 of the above is formed.

It is formed in the vicinity of the upper end surface 521A so as to be parallel to the upper end surface. Specifically, the separation dimension L20 between the straight line LN1 and the straight line LN2 is longer than twice the length (2.5 mm × 2 = 5 mm) of the plate thickness dimension L15 of the second light guide plate 521 (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 (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.

By being formed at a position more than twice the thickness dimension L15, the strength in the vicinity of the peripheral edge of the second light guide plate 521 is appropriately maintained so as not to be significantly reduced by the holes.

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

It is slightly longer than the diameter L4 (L3B> L4). Therefore, in a state where the second positioning boss 552 is inserted into the second hole portion 602, a gap S2 (L3A-L4) in the left-right direction is generated between the second hole portion 602 and the second positioning boss 552. , There is almost no vertical gap S3 (L3B-L4).

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 have substantially the same size (S1 (L1-L2) = S3 (L3B-L4)). That is, the second hole portion 602 allows the second light guide plate 521 to move in the left-right direction with respect to the second positioning boss 552, and does not allow the second light guide plate 521 to move in the up-down direction.

As shown in FIGS. 15B, 16 and 18, at a position below the left side of the hypotenuse of the upper end surface 511A of the first light guide plate 511, the first positioning is provided so as to project from the left side of the back surface of the middle holding member 504.

It is formed in the vicinity of the upper end surface 511A so as to be parallel to the upper end surface. Specifically, the separation dimension L21 between the straight line LN3 and the straight line LN4 is longer than twice the length (2.5 mm × 2 = 5 mm) of the plate thickness dimension 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 (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.

In the state where the first positioning boss 571 is inserted into the first hole portion 611, a gap S11 (L5-L6) in the left-right and vertical directions is substantially not formed between the first hole portion 611 and the first positioning boss 571. That is, the first positioning boss 571 is fitted into the first hole portion 611.

The left-right dimension L7A of the second hole portion 612 is longer than the diameter L8 of the second positioning boss 572 (L7A> L8), and the vertical dimension L7B of the second hole portion 612 is the second positioning boss 572. It is slightly longer than the diameter L8 (L7B> L8). Therefore, in a state where the second positioning boss 572 is inserted into the second hole portion 612, a gap S12 (L7A-L8) in the left-right direction is generated between the second hole portion 612 and the second positioning boss 572. , There is almost no vertical gap S13 (L7B-L8).

The gap S12 in the left-right direction is larger than the gap S11 (S12 (L7A-L8)> S11 (L5-L6)). Further, the gap S11 and the gap S13 have substantially the same size (S11 (L5-L6) = S13 (L7B-L8)). That is, the second hole portion 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 movement in the up-down direction.

Further, as shown in FIG. 18B, the vertical dimension L7C of the second hole portion 622 is longer than the diameter L8 of the second positioning boss 542 (L7C> L8), and the second hole portion 622 has a length L7C. The left-right dimension L7D is slightly longer than the diameter L8 of the second positioning boss 542 (L7D> L8). Therefore, in a state where the second positioning boss 542 is inserted into the second hole portion 622, a vertical gap S14 (L7C-L8) is generated between the second hole portion 622 and the second positioning boss 542. , There is almost no gap S15 (L7D-L8) in the left-right direction.

The vertical gap S14 is larger than the gap S11 (S14 (L7C-L8)> S11 (L5-L6)). Further, the gap S11 and the gap S15 have substantially the same size (S11 (L5-L6) = S15 (L7D-L8)). That is, the second hole portion 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 movement in the up-down direction.

The diameter L2 of the first positioning boss 551 and the diameter L4 of the second positioning boss 552 are substantially the same (L2 = L4), and the diameter L6 of the first positioning boss 571 and the diameter L6 of the second positioning boss 57 2 , 542, which is almost the same size as the diameter L8 (L6 = L8).

Further, the ridges 562B of the middle holding member 504 are arranged in close proximity to the upper side portion and the left and right oblique side portions on the front surface of the first light guide plate 511, and the rear holding member 505 is arranged on the upper side portion and the left and right side portions on the back surface. The convex portions 549A of the uneven portions 549L and 549R of the above are arranged in close proximity to each other. The ridges 562F and 562B and the ridges 549A of the rugged portions 549L and 549R function as holding portions of the holding body.

Further, 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, the second positioning boss 527,552,542, the third positioning boss 573A, 573B, 543A, 543B are the first hole portion 601,611, the second hole portion 602,612,622, the third hole portion 633A, By being inserted into the 633B, 643A, and 643B, respectively, the mounting positions of the first light guide plate 511 and the second light guide plate 521 with respect to the holding body are determined, and downward deviation from the holding body is prevented.

Next, the 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 an acrylic resin material and are made of a transparent plate having a plate thickness dimension L15 of about 2.5 mm, as described above, the first light guide plate 511 and the second light guide plate 521 respond to changes in the temperature inside the pachinko gaming machine 1. Expansion and contraction occur.

In this embodiment, for example, as shown in FIG. 23, the separation dimension L40 between the first hole portion 611 and the third hole portion 643B in the first light guide plate 511 is about 442 mm, and in this case, the dimensional tolerance in manufacturing. Is about ± 0.6 mm, and a maximum elongation of about 1.6 mm occurs with respect to a temperature change of 40 degrees. Therefore, if the positions of the first hole portion 611 and the third hole portion 643B are fixed, an irreversible warp 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. 22 (A), 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 first hole portion 601 is filled with the second light guide plate 521. 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 portion 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, but the first hole Since the portion 601 is fitted to the first positioning boss 551 formed on the front holding member 503, it extends radially (in the direction of the arrow in the figure) with respect to the first hole portion 601.

Here, the first hole portion 601 and the second hole portion 602 are provided in the vicinity of the upper end surface 521A into which the light emitted from the emission surface 590A of the second condenser lens 524 is incident, and the first hole portion 602 is provided. Since the vertical gap S1 with the positioning boss 551 and the vertical gap S3 with the second positioning boss 552 are small, the upward extension width from the first hole portion 601 and the second hole portion 602 is suppressed to be small. be able to. Therefore, the upper end surface 521A of the second light guide plate 521 extends toward the upper second condensing lens 524, so that the distance dimension from the second condensing lens 524 is one position in the left-right direction (for example, the right position). Is different from another position (for example, the left side position), that is, the positional relationship between the exit surface 590A and the upper end surface 521A of the second condensing lens 524 is deviated, or the upper end surface 521A is the second condensing surface. It is possible to prevent the second condenser lens 524 from being damaged or damaged due to 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 portion 602 is larger than the gap S1, the extension to the left with respect to the first hole portion 601 is allowed. As shown in B), even when the second hole portion 602 is largely displaced to the left side with respect to the second positioning boss 552, the second positioning boss 552 for positioning the second light guide plate 521 at the front mounting position is provided. Since it is possible to avoid breaking by pressing, it is possible to prevent the incident of light from the second condensing lens 524 into the upper end surface 521A from being adversely affected by the positional deviation with respect to the front holding member 503 and the middle holding member 504.

Since the second light guide plate 521 is not provided with a hole for positioning other than the first hole 601 and the second hole 602 on the upper side, it extends downward with reference to the first hole 601. Will be tolerated.

Next, the first light guide plate 511 will be described. As shown in FIG. 23 (A), 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 first positioning boss 571 is fitted into the hole 611, the 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 substantially vertically oriented. A second positioning boss 542 is inserted at the center position. Further, at substantially the center position of the third hole portions 633A and 633B, third positioning bosses 573A and 573B are provided so that the axial center is located at the center of the third hole portions 633A and 633B, and the third hole portion is provided. Third positioning bosses 543A and 543B are provided at substantially the center positions of 643A and 643B so that the axial centers are located at the centers 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, since the first hole portion 611 is fitted to the first positioning boss 571 formed in the middle holding member 504, it extends radially (in the direction of the arrow in the figure) with respect to the first hole portion 611. become.

Here, the first hole portion 611 and the second hole portion 612 are provided in the vicinity of the upper end surface 511A to which the light emitted from the emission surface 590A of the first condensing lens 514 is incident, and the first hole portion 611 is provided. 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 571 are small, the first hole 611 and the second hole The width of extension from the portion 612 in the upward direction can be suppressed to be small. Therefore, the upper end surface 511A of the first light guide plate 511 extends toward the upper first condensing lens 514, so that the distance dimension from the first condensing lens 514 is one position in the left-right direction (for example, the right position). Is different from another position (for example, the left side position), that is, the positional relationship between the exit surface 590A and the upper end surface 511A of the first condensing lens 514 is deviated, or the upper end surface 511A is the first condensing surface 511A. It is possible to prevent the first condensing lens 514 from being damaged or damaged due to contact with the lens 514 or the like.

On the other hand, since the gap S12 between the second positioning boss 572 and the second hole portion 612 is larger than the gap S11, the extension to the right with respect to the first hole portion 611 is allowed. As shown in B), even when the second hole portion 612 is largely displaced to the right side 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 breaking, the displacement of the front holding member 503, the middle holding member 504, and the rear holding member 505 adversely affects the incident light from the first condensing lens 514 to the upper end surface 511A. Can be prevented.

Further, the first hole portion 611 and the second hole portion 622 are provided in the vicinity of the left end surface 511B into which the light emitted from the emission surface 590A of the first condensing lens 519 is incident, and the first hole portion 611 and the second hole portion 622 are provided. Since the gap S11 in the left-right direction between the portion 611 and the first positioning boss 571 and the gap S15 in the left-right direction between the second hole portion 612 and the second positioning boss 542 are small, the first hole portion 611 and the second hole portion The width of extension from 622 to the left can be kept small. Therefore, the left end surface 511B of the first light guide plate 511 extends to the left side of the first condensing lens 519, so that the distance dimension from the first condensing lens 519 is one position in the vertical direction (for example, the upper position). ) And another position (for example, the lower position), that is, the positional relationship between the exit surface 590A and the left end surface 511B of the first condenser lens 519 is deviated, or the left end surface 511B is the first. It is possible to prevent the first condenser lens 519 from being damaged or damaged due to contact with the condenser lens 519.

On the other hand, since the gap S14 between the second positioning boss 542 and the second hole portion 622 is larger than the gap S11, downward elongation with respect to the first hole portion 611 is allowed. 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 portion 622 is largely displaced downward with respect to the second positioning boss 527. Since it is possible to avoid breaking by pressing the lens, the displacement of the front holding member 503, the middle holding member 504, and the rear holding member 505 adversely affects the incident of light from the first condensing lens 519 to the left end surface 511B. It can be prevented from reaching.

Further, the 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 boss 573A, 573B, 543A, 543B is the first hole portion 611. Since the gap S11 with the first positioning boss 571 is larger than the gap S11, the extension in the front-rear and left-right directions (all directions) with respect to the first hole 611 is allowed, and therefore, as shown in FIG. 23 (B), The first light guide plate 511 is positioned at the rear mounting position even when the third hole portions 633A, 633B, 643A, and 643B are largely displaced in any direction with respect to the third positioning bosses 573A, 573B, 543A, and 543B. Because it is possible to avoid pressing and breaking the third positioning bosses 573A, 573B, 543A, and 543B, the first condensing due to misalignment with respect to the front holding member 503, the middle holding member 504, and the rear holding member 505. It is possible to prevent the incident of light from the lenses 514 and 519 on the upper end surface 511A and the left end surface 511B from being adversely affected.

In addition, in FIG. 22 and FIG. 23, the case where the first light guide plate 511 and the second light guide plate 521 are thermally expanded has been described. When the internal temperature of the machine 1 drops and the first light guide plate 511 and the second light guide plate 521 contract, although not particularly shown, they contract radially with reference to the first hole portions 601, 611, that is, , The peripheral edge 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, 611.

Even in such a case, the second positioning boss 552,572,542 is inserted at a substantially central position in the longitudinal direction of the second hole portions 602, 612, 622, and the third hole portions 633A and 633B are abbreviated. Third positioning bosses 573A and 573B are provided at the center position so that the axial center is located at the center of the third hole portions 633A and 633B, and the third hole portions 643A and 643B are located at substantially the center position. 3 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 552,572,542 and the third positioning bosses 573A and 573B are provided. , 543A, 543B, 2nd hole 602, 612, 622 and 3rd hole 633A, 633B, 643A, 643B are allowed to move to the 1st hole 601, 611 side, so that the second positioning boss 552 , 527,542 and the third positioning bosses 573A, 573B, 543A, 543B are prevented from being damaged.

Next, the effect display mode by the light guide plate device 500 will be described with reference to FIGS. 24 and 25. 24A and 24B are explanatory views showing a second effect display mode and (B) a first effect display mode. 25 is a diagram showing a light guide mode of an LED, a condenser lens, and a light guide plate in FIG. 25, and FIG. 25B is a sectional view taken along line LL 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 light collecting lens 524, and the second light collecting lens The light is guided while reflecting inside the 524, is emitted from the exit surface 590A, and is incident on the upper end surface 521A of the second light guide plate 521. Then, the light incident from the upper end surface 521A is guided while being internally reflected, and is 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 second. When the region corresponding to the reflection portion 596 of the light guide plate 521 emits light, the second effect display in which the characters "extreme heat!" Is emitted and displayed is performed.

Further, 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 light collecting lens 514 and is guided while reflecting the inside of the first light collecting lens 514. It is emitted from the exit surface 590A and is incident on the upper end surface 511A of the first light guide plate 511. Then, the light incident from the upper end surface 511A is guided while being internally reflected, and is 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 of the light guide plate 511 corresponding to the reflection portion 598 emits light, the second effect display in which the characters "extreme heat!" Is emitted and displayed is performed. When the movable body 301 is located in the standby position, the characters "extreme heat!" Are emitted and displayed on the front side of the movable body 301.

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 "super heat!" Are superimposed on the front and back on both the second light guide plate 521 and the first light guide plate 511 to display light emission. Will be done.

On the other hand, when the first light guide plate LED 517 on the left side is turned on, the light from the first light guide plate LED 517 is incident on the incident surface 591A of the first condensing lens 519, and the light guide is reflected inside the first condensing lens 519. Then, the light is emitted from the exit surface 590A and is incident on the left end surface 511B of the first light guide plate 511. Then, the light incident from the left end surface 511B is guided while being internally reflected, and is 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 of the light guide plate 511 corresponding to the reflection portion 598 emits light, the first effect display in which the effect is emitted and displayed is performed. When the movable body 301 is located at the effect position, the effect is emitted and displayed around the movable body 301.

In this embodiment, the effect control CPU 120 can execute a second effect display that emits and displays the characters "super heat!" As a jackpot notice effect that suggests the possibility of a big hit. That is, this second effect display is a character that suggests that there is a high possibility of a big hit for the player, and the player does not perform a suitable light emission display due to thermal expansion of the first light guide plate 511 and the second light guide plate 521. If the characters cannot be recognized, it will be meaningless as a notice effect, so it is more important than the first effect display in which the effect that decorates the surroundings of the movable body 301 that has just moved to the effect position is displayed by light emission. It is said that. Specifically, as described above, the thermal expansion of the first light guide plate 511 and the second light guide plate 521 causes the positional relationship between the exit surface 590A and the upper end surfaces 511A and 521A to shift, or the second condenser lens 524. Or, if the first condensing lens 514 is damaged and it becomes impossible for the player to emit and display the characters "super heat!" In a manner that can be recognized by the player, it becomes impossible to suggest the possibility of a big hit. As a result, there is a risk that the player's expectation cannot be suitably improved.

On the other hand, regarding the effect, the player uses the effect because the first light guide plate 511 is thermally expanded and the positional relationship between the exit surface 590A and the left end surface 511B is displaced, or the first condensing lens 519 is damaged. When the light emission cannot be displayed in a recognizable manner, the decorativeness is reduced, but the possibility of a big hit cannot be suggested.

Therefore, in this embodiment, the parts corresponding to the first light guide plate LED 512 and the second light guide plate LED 522 that emit light when the second effect display, which is more important than the first effect display, is executed, are 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 condensing lens 524 and the first condensing 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 so 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 portion 622 is not provided so that the straight line passing through the first hole portion 611 and the second hole portion 622 is parallel to the straight line along the left end surface 511B. However, the straight line passing through the first hole portion 611 and the second hole portion 622 may be provided so as to be parallel to the straight line along the left end surface 511B.

The first light guide plate 511 and the second light guide plate 521, which can perform the effect display (light emission display), and the light incident from the light emitting means are transmitted to the first light guide plate 511 and the second light guide plate 521. A mounted portion (for example,) to which the first condensing lens 514,519 and the second condensing lens 524 and the first condensing lens 514,519 and the second condensing lens 524 as the light guide member emitted toward the light source are attached. The back surface of the front holding member 503 and the back surface of the first light guide plate LED substrate 513, the front surface of the second light guide plate LED substrate 523 and the front surface of the rear holding member 505, and the back surface of the first light guide plate LED substrate 518L). The 1 condensing lens 514,519 and the 2nd condensing lens 524 have positioning holes 530, 594 and positioning holes 595,580 as insertion portions provided in the attached portion in a state of being attached to the attached portion. Condensing lens positioning bosses 593F and 593B that can be inserted into the positioning hole 595A are provided so as to project.

By doing so, by inserting the condensing lens positioning bosses 593F and 593B into the positioning holes 530, 594, the positioning holes 595 and 580, and the positioning holes 595A, the first condensing lens 514,519 and the second condensing lens are inserted. Since the mounting position of the lens 524 is determined, the first condenser lens 514 and the second condenser lens 524 can be suitably mounted.

Further, the condensing lens positioning bosses 593F and 593B of the first condensing lens 514,519 and the second condensing lens 524 are provided with the first light guide plate LED 512,517 and the second light guide plate LED522, respectively. Accurately positioned with respect to the first light guide plate LED 512,517 and the second light guide plate LED522 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. Therefore, the light from the first light guide plate LED 512, 517 and the second light guide plate LED 522 can be preferably incident.

Further, the condensing lens positioning bosses 593F and 593B are provided so as to project on the surface of the surface orthogonal to the light emitting surface 590A and the incident surface 591A, so that the light incident on the inside is reflected. It is less likely to have an effect (see FIG. 14).

By doing so, the first condensing lens 514 and the second condensing lens 524 can be suitably attached.

Further, a front holding member 503, a middle holding member 504, and a rear holding member 505 as holding bodies are provided, and the holding body includes a first light guide plate 511 and a second light guide plate 521 in front holding member 503, middle holding member 504, and middle holding member 504. It has lens hooks 531, 564 and ridges 581 as regulating parts for restricting the movement of the first condensing lens 514 and the second condensing lens 524 while being held by the rear holding member 505.

By doing so, the first condensing lens 514 and the second condensing lens 524 can be suitably attached. Further, since the holding pieces 592A and 592B locked by the lens hooks 531 and 564 and the protrusions 581 are formed on the left and right ends of the first condensing lens 514 and the second condensing lens 524, they are guided. It can be installed so that the light is not affected as much as possible.

Further, in the present embodiment, the light from the first light guide plate LED 512, 517 and the second light guide plate LED 522 passes through the first light guide plate 514, 589 and the second light condenser lens 524, and the first light guide plate 511 and the second light guide plate 511 and the second light guide plate 511. It is incident on the light guide plate 521, and the first condensing lens 514,519 or the second condensing lens 524 and the first light guide plate 511 or the second light guide plate 521 are made of the same material (for example, acrylic resin material). However, the present invention is not limited to this, and for example, the condenser lens may be made of a material different from that of the light guide plate. Specifically, by using a material that is less likely to be deformed by heat than the light guide plate, the light from the LED can be suitably guided to the light guide plate. Further, even if the materials are not different, the volume may be smaller than that of the light guide plate, or the plate thickness may be increased so that the plate is less likely to be deformed.

Further, the first condensing lens 514,519 and the second condensing lens 524 are interposed between the first light guide plate 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, the heat from the first light guide plate LED 512, 517 and the second light guide plate LED 522 is less likely to be transferred to the first light guide plate 511 and the second light guide plate 521, so that 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 less likely to be deformed by a temperature change than the light guide plate. It may be made of the same material as the 1 light guide plate 511 and the 2nd light guide plate 521. By doing so, the light guide plate and the holding body expand and contract in the same manner due to the temperature change, so that it is possible to cope with thermal expansion.

In this embodiment, the effect of 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. Further, the degree of expectation can be different depending on the timing at which the effect of the light guide plate is executed. If the player's attention can be drawn to the execution timing of the effect by the light guide plate, the 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, and for example, when the variation display of 1 starts, before the reach state occurs in the variation display of 1, and when the reach state occurs in the variation display of 1. After the reach state occurs in the fluctuation display of 1, the jackpot game state and the like can be mentioned. In addition, the timing at which various effects other than the effect by the light guide plate are executed can be mentioned. More specifically, the execution timing of the effect by the light guide plate includes the timing when the movable body effect by the movable body 301 of the effect unit 300 is executed, the timing when the player operates the stick controller 31A or the push button 31B, and the like. Can be mentioned. In addition, in the variation display of 1, 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 during the jackpot game state is not particularly limited, but for example, when the effect indicating that the jackpot has become a type that shifts to the high probability state is executed, the round continues. When the effect to be shown is executed, when the effect to indicate that the hold memory that is a big hit is stored is executed, and the like can be mentioned. Further, in the case of a gaming machine of a type that shifts to a probabilistic state based on the passage of the gaming ball into the specific region, there is a time when an effect indicating that the gaming ball has passed through the specific region is executed.

In addition, the effect by the light guide plate is, for example, a period controlled to a specific gaming state (for example, a high base state, a low base state, a high probability state, a low probability state) or a specific effect mode (for example, high). It may be possible to execute at a predetermined timing during a period controlled by a latent mode (mission mode) that makes it difficult for the player to recognize whether or not it is a stochastic state. Further, it may be made feasible as an effect for fluctuations that have not yet been started (so-called look-ahead effect).

Further, when the gaming machine includes two or more light guide plates, the execution timing of the effect by the light guide plates may differ depending on the light guide plates. Further, in a plurality of light guide plates, the execution timing of the effect by the light guide plates may be the same. For example, the effect of the first light guide plate may be executed, and then the effect of the second light guide plate may be executed, or the effect of the first light guide plate and the effect of the second light guide plate may be executed at the same time. As a more specific example, in the variation display of 1, the effect by the first light guide plate is executed before the reach state occurs, and the effect by the second light guide plate is performed when the reach state occurs or after the reach state occurs. It can be executed.

It should be noted that the effect of the light guide plate may be executed in parallel with the effect other than the effect of the light guide plate. Further, the effect of the light guide plate may be restricted when an effect other than the effect of the light guide plate is being executed.

Further, in the effect of the light guide plate, the degree of expectation can be different depending on the timing at which the effect is executed. For example, as the timing at which the effect of the light guide plate is executed in the variation display of 1, when the variation display of 1 starts, when the reach state occurs in the variation display of 1, and after the reach state occurs in the variation display of 1. When there are three timings, and the effect by the light guide plate is executed once in 1 variation display, the expectation level increases as the timing when the effect by the light guide plate is executed in 1 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 different depending on the timing at which the effect by the light guide plate is executed and the light guide plate on which the effect by the light guide plate is executed. For example, as the timing at which the effect of the light guide plate is executed in the variation display of 1, when the variation display of 1 starts, when the reach state occurs in the variation display of 1, and after the reach state occurs in the variation display of 1. There are three timings, the first light guide plate and the second light guide plate are provided as the light guide plate, and the effect by the second light guide plate is higher than the effect by the first light guide plate, and the first variation display of 1 is When the effect of the 1st light guide plate or the effect of the 2nd light guide plate is executed once, the first light guide plate increases the expectation as the timing of the effect of the light guide plate is executed later in the variation display of 1. The degree of expectation can be 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 the variation display of 1, the effect with the highest degree of expectation is obtained. In this way, by attracting the player's attention to the execution timing of the effect by the light guide plate and which light guide plate is used to execute the effect by the light guide plate, the effect of the effect by the light guide plate can be further improved. It is possible to further improve the interest based on the production by.

The "expectation degree" refers to the degree of expectation that the gaming machine is controlled in an advantageous state for the advantageous player. For example, in the above-mentioned gaming machine, when the effect by the light guide plate is executed in the variable display of 1, the degree of expectation for the big hit game state and the degree of expectation for the transition to the effect with a high possibility of big hit (so-called super reach effect). Expectations can be raised. In addition, when the effect by the light guide plate is executed during the big hit game 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 for the hold memory to be the big hit, etc. Expectations can be raised.
