  As described above, the first start port switch 14a, the second start port switch 15a, and the count switch 23 are configured using proximity switches, and the first to third winning check switches 14b, 15b, and 23a are using photo sensors. However, the detection methods of the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the count switch 23 and the third winning confirmation switch 23a are shown in this embodiment. For example, if the detection method is different between the first and second start port switches 14a and 15a and the count switch 23 and the first to third winning confirmation switches 14b, 15b and 23a, for example, Photo sensors are used as the start port switches 14a and 15a and the count switch 23, and the first to third prize winning confirmation switches 14b and 15 , It may be used proximity switch as 23a. In this case, based on the detection results of the first and second start port switches 14a and 15a and the count switch 23, which are photosensors, special symbol variation display and prize ball payout processing are executed, and the first to third winning prizes which are proximity switches. The detection results of the confirmation switches 14b, 15b, and 23a are used only for the determination of the abnormal winning of the first starting winning port 13a, the second starting winning port 13b, and the big winning port. For example, instead of a proximity switch or an optical photosensor that is an electromagnetic switch, the first and second start port switches 14a and 15a and the count switch 23 or the first to third prize confirmation switches 14b, 15b, and 23a are used. Alternatively, a mechanical switch (such as a micro switch) may be used.

  Further, in this embodiment, the first and second start port switches 14a and 15a count switch 23 that trigger the execution of the special symbol change display and the prize ball payout process are the first to third prizes used for the determination of the abnormal winning. Although provided on the upstream side of the confirmation switches 14b, 15b, 23a, it may be provided on the downstream side of the switch used for the determination of the abnormal winning.

  Then, the game control microcomputer 1560 uses the first start port switch based on the detection signal input from the first start port switch 14a (proximity switch) and the detection signal input from the first winning confirmation switch 14b (photo sensor). When it is determined that the difference between the number of game balls detected at 14a and the number of game balls detected at the first winning confirmation switch 14b exceeds a predetermined threshold (in this example, 15 or more) As an error, it is determined that an abnormal winning to the first start winning opening 13a has occurred. The game detected by the second start port switch 15a based on the detection signal input from the second start port switch 15a (proximity switch) and the detection signal input from the second winning confirmation switch 15b (photo sensor). When it is determined that the difference between the number of balls and the number of game balls detected by the second winning confirmation switch 15b exceeds a predetermined threshold (in this example, 15 or more), a second error is generated as a predetermined error. It is determined that an abnormal winning to the winning opening 13b has occurred. In addition, based on the detection signal input from the count switch 23 (proximity switch) and the detection signal input from the third winning confirmation switch 23a (photo sensor), the number of game balls detected by the count switch 23 and the third winning prize are determined. If it is determined that the difference from the number of game balls detected by the confirmation switch 23a exceeds a predetermined threshold (in this example, 5 or more), an abnormal winning at the big winning opening occurs as a predetermined error. It is determined that

  In this way, the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the count switch 23 and the third winning confirmation switch 23a are of different detection methods. By configuring the sensor (in this example, a proximity switch and a photo sensor), the actual number of winnings to the first starting winning port 13a, the second starting winning port 13b, and the big winning port using, for example, electromagnetic waves is actually When an illegal act that causes recognition to be greater than the number of winnings is made, there is a difference between the number of game balls detected by the proximity switch and the number of game balls detected by the photo switch, thereby controlling the game. Since the microcomputer 1560 determines that an abnormal winning has occurred when the number of difference balls exceeds a predetermined threshold, it is possible to take a certain measure against illegal acts.

  The game area 7 is provided with decorative members 25L and 25R having a plurality of decorative LEDs 25a that emit light in accordance with the gaming state, and an outlet 26 for collecting the game balls that have not won a prize is provided at the bottom.

  Decorative members 25L and 25R having decorative LEDs 25a blinking and displayed during the game are provided around the left and right sides of the game area 7, and there is an out port 26 for collecting the game balls that have not won a prize.

  Four speakers 27 that emit sound effects are provided on the left, right, top, and bottom of the outside of the game area 7. On the outer periphery of the game area 7, a top frame LED 28a, a left frame LED 28b, and a right frame LED 28c are provided. The top frame LED 28a, the left frame LED 28b, the right frame LED 28c, and the decoration LED 25a are examples of a decoration light emitter provided in the gaming machine.

  Although not shown in FIGS. 1 and 2, a prize ball lamp that is turned on during the prize ball payout is provided in the vicinity of the left frame LED 28 b, and when the supply ball is cut in the vicinity of the top frame LED 28 a. A ball-out lamp that is lit is provided. Note that the award ball lamp and the out-of-ball lamp are controlled to be turned on by the effect control microcomputer mounted on the effect control board when the award ball is being paid out or when the out-of-ball is detected. Further, although not shown in particular, a prepaid card unit (hereinafter referred to as “card unit”) 50 that enables lending a ball by inserting a prepaid card is installed adjacent to the pachinko gaming machine 1. .

  A game ball launched from the ball striking device by the player's operation enters the game area 7 through the hit ball rail, and then descends the game area 7. When the game ball enters the first start winning port 13a and is detected by the first start port switch 14a, if the variable display of the first special symbol can be started (for example, the variable display of the special symbol ends, 1), the first special symbol display 8a starts variable display (variation) of the first special symbol, and the effect display device 9 starts variable display of the effect symbol (decoration symbol). Is done. In other words, the variable display of the first special symbol and the effect symbol corresponds to winning in the first start winning opening 13a. If the variable display of the first special symbol cannot be started, the first reserved memory number is increased by 1 on the condition that the first reserved memory number has not reached the upper limit value.

  When the game ball enters the second start winning port 13b and is detected by the second start port switch 15a, if the variable display of the second special symbol can be started (for example, the special symbol variable display ends, 2), the second special symbol display 8b starts variable display (variation) of the second special symbol, and the effect display device 9 starts variable display of the effect symbol (decoration symbol). Is done. That is, the variable display of the second special symbol and the effect symbol corresponds to winning in the second start winning opening 13b. If the variable display of the second special symbol cannot be started, the second reserved memory number is increased by 1 on condition that the second reserved memory number has not reached the upper limit value.

  The variable display of the first special symbol on the first special symbol display 8a and the variable display of the second special symbol on the second special symbol display 8b are stopped when a certain time has elapsed. If the special symbol (stop symbol) at the time of stoppage is a big hit symbol (specific display result), it will be “big hit”, and the special symbol (stop symbol) at the time of stop will be different from the big hit symbol (predetermined display result) Is “small hit”, and if the special symbol at the time of stoppage (stop symbol) is stopped and displayed, a special symbol different from the big hit symbol and the small hit symbol is “lost”.

  After the variable 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. Further, after the variable display result in the special figure game becomes “small hit”, the game is controlled to the small hit game state different from the big hit game state.

  In this embodiment, when the big win symbol corresponding to “non-probability change” or “probability change A” in the special figure game is stopped and displayed, the first big win state (15 rounds) as the multi-round specific game state is displayed. (Big hit state). In the big hit gaming state (usually 15 round big hit state), the special winning prize ball device 20 has a predetermined winning period (for example, 29.5 seconds) or a predetermined number (for example, eight) winning balls. During the period until the occurrence of the round, the round is performed to change the special variable winning ball apparatus 20 to the first state (open state) advantageous to the player by opening the special winning opening. In this way, the special prize opening door that has opened the special prize opening during the round is received by receiving the game ball falling on the surface of the game board 6, and then the special prize opening is closed, so that the special variable prize ball is closed. The device 20 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the 15 round big hit state, the number of executions of the round, which is the open cycle of the big prize opening, becomes the first round number (for example, “15”). A game in the 15 round big hit state in which the number of round executions is “15” is also referred to as a 15-time open game. In such a 15 round big hit state, every time a game ball wins a big winning opening, 15 balls (prize balls) are obtained. The 15 round round big hit state is also referred to as a first specific gaming state.

  When the big hit symbol corresponding to “probability change B” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the second big hit state (high-speed 15 round big hit state) as the multi-round specific gaming state. In the second big hit state, the special prize winning ball device 20 has a big winning opening door in a second period (for example, 0.5 seconds) shorter than the first period in the first big hit state or a predetermined number (for example, three) of winnings. The round that changes the special variable winning ball apparatus 20 to the first state (open state) advantageous to the player is performed by opening the grand prize opening in the period until the ball is generated. In this way, the special prize opening door that has opened the special prize opening during the round is received by receiving the game ball falling on the surface of the game board 6, and then the special prize opening is closed, so that the special variable prize ball is closed. The device 20 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the second big hit state, the number of executions of the round, which is the opening cycle of the big prize opening, becomes the second round number (for example, “15”).

  In such a second big hit state, 15 game balls (prize balls) can be obtained if a game ball wins the big winning opening, but the opening period of the big winning opening is the second period (0.5 seconds). It is very short. For this reason, the second big hit state is a big hit gaming state in which a ball (prize ball) cannot be obtained substantially. The second big hit state is also referred to as a second specific gaming state. Further, the second big hit state may be one in which the number of round executions is smaller than that in the first big hit state. That is, in the second big hit state, the period in which the big prize opening is changed to the open state in each round is a second period shorter than the first period in the first big hit state, and the number of round executions is the first big hit state. It may be at least one of the second number of rounds less than the first number of rounds.

  In addition, after the first jackpot state is ended based on the fact that the jackpot symbol corresponding to “non-probable change” is stopped and displayed as a confirmed special symbol in the special figure game, it is compared with the normal state as one of the special gaming states. The time is controlled to be in a time-short state in which time-shortening control (short-time control) is performed in which the variable symbol display time (special-figure variation time) is shortened in the special figure game. Here, the normal state is a normal game state as a game state different from a specific game state such as a big hit game state, a probability change state, and a short time state, and an initial setting state of the pachinko gaming machine 1 (for example, a system reset is performed). As in the case where the initialization process is performed after the power is turned on, the same control is performed. If the time-short state is terminated when any of the conditions of the special game is executed a predetermined number of times (for example, 100 times) and the variable display result is “big hit” is satisfied first, Good. Thus, like the big hit symbol special symbol corresponding to “non-probable change”, the big hit symbol controlled to the short-time state after the first big hit state based on being stopped and displayed as the confirmed special symbol in the special symbol game is This is called a non-probable big hit symbol (also referred to as “normal big hit symbol”). Further, the fact that the non-probable variable big hit symbol among the big hit symbols is stopped and displayed and the variable display result becomes “big hit” is called “non-probable big hit” (also referred to as “normal big hit”).

  The jackpot symbol corresponding to “probability variation B” is displayed after the first big hit state is ended based on the fact that the jackpot symbol corresponding to “probability variation A” is stopped and displayed as a confirmed special symbol in the special symbol game. After the second big hit state is ended based on the fact that it is stopped and displayed as a confirmed special symbol in the game, the special figure variation time is shortened as one of the special game states different from the short-time state, for example, compared with the normal state. Along with the time-shortening control, the state is controlled to a probability variation state (high probability state) in which probability variation control (probability variation control) is continuously performed. In this probabilistic state, the variable display result of each special figure game and decorative design is improved so that the probability that the variable display result will be “big hit” and further controlled to the big hit gaming state will be higher than in the normal state and the short-time state. To do. Such a probability change state continues until the next variable display result is a “big hit”, regardless of the number of executions of the special game.

  Like the jackpot symbol corresponding to such “probability change A”, the jackpot symbol controlled to the probability change state after the first jackpot state based on being stopped and displayed as the confirmed special symbol in the special figure game is the probability change jackpot symbol. It is called. In addition, like the jackpot symbol corresponding to “probability change B”, the jackpot symbol controlled to the probability change state after the jackpot game state based on being stopped and displayed as the confirmed special symbol in the special figure game is the sudden hit bonus symbol. It is called. In addition, the probability variation big hit symbol out of the big hit symbol is stopped and displayed and the variable display result becomes “big hit” is called “probable big hit”. The fact that the sudden hit symbol is stopped and displayed and the variable display result is “big hit” is called “surprise big hit” (also referred to as “surprise big hit”). These jackpot symbols are arbitrary. For example, in order to prevent the player from recognizing the jackpot type, the jackpot symbol may not be a number but may be a predetermined symbol or the like. .

  After the special symbol corresponding to “small hit” is stopped and displayed as the confirmed special symbol in the special symbol game, the small hit game state is controlled. In this small hit game state, similarly to the second big hit state, a variable winning operation is performed in the special variable winning ball apparatus 20 to change the big winning opening to the first state (open state) advantageous to the player. That is, in the small hit gaming state, for example, the operation of setting the special variable winning ball device 20 to the first state (open state) over the second period is the second number {the number of executions equal to the second number of rounds (in this example, 15 It is repeatedly executed until it reaches (time)}. In the small hit gaming state, as in the second big hit state, the period during which the special variable winning ball apparatus 20 is in the first state is the second period, and the number of executions of the operation in the first state is the second. Control may be performed so that at least one of the number of times is performed. After the small hit gaming state ends, the gaming state is not changed, and the game state before the variable display result becomes “small hit” is continuously controlled. However, if the number of executions of the special figure game in the special gaming state has reached a predetermined number when the special figure game with the variable display result of “small hit” is executed, after the end of the small hit gaming state, The special gaming state may end and return to the normal state. A game in the small hit gaming state in which the number of times that the special variable winning ball apparatus 20 is set to the first state by the variable winning operation is “15” is also referred to as a 15-time open game, similar to the game in the second big hit state. When the winning ball device provided separately from the special variable winning ball device 20 in each round in the second big hit state is changed to the first state, the same as in the second big hit state even in the small hit gaming state In the aspect, the winning ball apparatus may be changed to the first state.

  In the probabilistic state and the short time state, the normal symbol display unit 10 controls the normal symbol in the normal symbol game so that the variation time of the normal symbol (ordinary symbol variation time) is shorter than that in the normal state. Control to improve the probability that the display result is “per normal figure” than in the normal state, and tilt control of the movable blade piece in the variable winning ball apparatus 15 based on the fact that the variable display result is “per normal figure”. The game ball can easily pass (enter) the second start winning opening 13b, such as control for making the tilt control time to be performed longer than that in the normal state, and control for increasing the number of tilts than in the normal state. Control that is advantageous to the player is performed by increasing the possibility that the start condition is satisfied. It should be noted that any one of these controls may be performed in the probability variation state or the short time state, or a plurality of controls may be performed in combination. As described above, the control that facilitates the entry of the game ball into the second start winning opening 13b in the probability change state or the short time state is also referred to as high release control. When the high opening control is performed, the frequency at which the second start winning opening 13b is in the expanded opening state is higher than when the high opening control is not performed. As a result, the second start condition for executing the special figure game using the second special figure in the second special symbol display 8b is easily established, and the special figure game can be executed frequently. In addition, the time until the variable display result becomes “big hit” is shortened. Therefore, in the probability variation state and the short time state, it becomes easier to enter the big hit gaming state than in the normal state. The period during which the high opening control can be executed is also referred to as a high opening control period, and this period may be the same as the period during which the gaming state in the pachinko gaming machine 1 is controlled to either the certain change state or the short-time state. . Further, it is also said that the gaming state is in the high base during the high opening control period. On the other hand, when it is not the high opening control period, it is said that the gaming state is in the low base. The short-time state in this embodiment is a gaming state also referred to as a low-probability high-base state, and the normal state is a gaming state also referred to as a low-probability low-base state, which is a probabilistic state that is not a high release control period. The latent probability changing state is a gaming state also called a high probability low base state.

  In this embodiment, after the end of the second big hit state based on the “probability big hit” corresponding to “probability change B” in the normal state, only the probability change control is performed, and the time-shortening control and the high opening control are performed. The process proceeds to the second probability variation control (latent probability variation state) that is not performed. Further, after the end of the second big hit state based on the fact that the “probable big hit” is made in the probability change state, the state shifts to the first probability change state where the time-shortening control and the high opening control are performed together with the probability change control.

  As described above, the probability variation state includes not only the time variation control and the high release control are performed together with the probability variation control but also the probability variation control only and the time reduction control and the high release control are not performed (latency probability variation). It may be. In addition, for example, after the first big hit state based on the fact that the variable display result in the special figure game is “probable big hit”, the first positive change state (high-speed control and high-open control are performed together with the positive change control (high When the number of executions of the special figure game reaches a predetermined number of times (for example, 70 times) without the special figure display result being “big hit”, the probability variation control is continued. However, the control may be performed in a second certain change state (also referred to as a highly accurate low base state) that is not performed after the time-shortening control or the high opening control is finished.

  Further, in this embodiment, after the second big hit state is ended based on the fact that the variable display result in the special game is “surprise big hit” in the probability changing state, the second probability changing state (latent probability changing state) is reached. Although the transition was made, not only the probability change state but also the first probability change even after the end of the second big hit state based on the fact that the variable display result in the special game is “abrupt big hit” when in the short time state You may make it transfer to a state. Alternatively, after the first big hit state based on the “probable big hit” is finished, it is controlled to the first positive change state until the special figure display result becomes “big hit” again, while the second big hit state based on the “surprise big hit” is controlled. After the completion, the process shifts to the first certain change state, and when the number of executions of the special figure game reaches a predetermined number without causing the special figure display result to be “big hit”, the second certain change state is entered. Also good. While the short-time control and the high-open control are started and ended simultaneously (interlocked), the start and end of the probability variation control is not necessarily linked to the start and end of the short-time control and high-open control. May be.

  In the “left”, “middle”, and “right” decorative symbol display areas provided in the effect display device 9, the special symbol game using the first special symbol and the second special symbol in the first special symbol display 8a. Corresponding to the start of one of the special figure games using the second special figure on the display unit 8b, the variable display (variation display) of the decorative symbols is started. In the period from the start of variable display of decorative symbols to the end of variable display due to the stop display of the fixed decorative symbols in the “left”, “middle”, and “right” decorative symbol display areas, The variable display state may be a predetermined reach state. Here, the reach state refers to a decorative pattern (“reach” which has not been temporarily stopped yet when the decorative pattern temporarily stopped displayed in the display area of the effect display device 9 forms a part of the jackpot combination. "Varying symbols") is a display state in which the variation continues, or a display state in which all or part of the decorative symbols change synchronously while constituting all or part of the jackpot combination. is there. Specifically, a part of the “left”, “middle”, and “right” decorative symbol display areas (for example, “left” and “right” decorative symbol display areas) constitutes a predetermined jackpot combination. In a remaining decorative symbol display area (for example, a “medium” decorative symbol display area, etc.) that has not yet been temporarily stopped when a decorative symbol (for example, a decorative symbol indicating the alphanumeric character “7”) is temporarily stopped. The display state in which the decorative symbols are changing, or all or part of the “left”, “middle”, and “right” decorative symbol display areas are synchronized while the decorative symbols constitute all or part of the jackpot combination. The display state is fluctuating.

Above the ball payout device 97, a ball break switch 187 is provided as a game medium break detection means. When the ball break switch 187 detects a ball break, the payout operation of the ball payout device 97 stops. When the ball break switch 187 detects a shortage of game balls, the game balls are replenished to the pachinko gaming machine 1 from the replenishment mechanism provided on the gaming machine installation island.

  When a large number of game balls as prizes based on winning a prize or a game ball based on a ball lending request are paid out and the hitting ball supply tray 3 is full, the game balls are guided to the surplus ball receiving tray 4 through the surplus ball guiding path. Further, when the game ball is paid out, a sensing lever (not shown) presses a full tank switch (not shown) as the storage state detection means, and the full tank switch as the storage state detection means is turned on. In this state, the rotation of the payout motor in the ball payout device is stopped, the operation of the ball payout device is stopped, and the driving of the ball hitting device is also stopped.

  FIG. 3 is a block diagram showing an example of the circuit configuration of the main board (game control board) 31. FIG. 3 also shows a payout control board 37, an effect control board 80, and the like. The main board 31 is equipped with a game control microcomputer 1560 (corresponding to game control means) for controlling the pachinko gaming machine 1 in accordance with a program. The game control microcomputer 1560 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as storage means used as a work memory, a CPU 56 for performing control operations in accordance with the program, and an I / O port unit 57. including.

The one-chip microcomputer only needs to include at least the RAM 55, and the ROM 54 may be external or internal. The I / O port unit 57 may be externally attached. The game control microcomputer 1560 further includes a random number circuit 53 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 1560, the CPU 56 executes control in accordance with the program stored in the ROM 54. Therefore, the game control microcomputer 1560 (or CPU 56) executes (or performs processing) hereinafter. Specifically, the CPU 56 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 31.

  The game control microcomputer 1560 has a built-in random number circuit 53. The random number circuit 53 is a hardware circuit that is used to generate a random number for determination for determining whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 53 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 53 is a hardware circuit that is used to generate a random number for determination for determining whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 53 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 53 has a numeric data update range selection / setting function (initial value selection / setting function and upper limit selection / setting function), numeric data update rule selection / setting function, and numeric data update rule selection. It has various functions such as a switching function. With such a function, the randomness of the generated random numbers can be improved.

  Further, the game control microcomputer 1560 has a function of setting an initial value of numerical data updated by the random number circuit 53. For example, a predetermined calculation is performed using the ID number of the game control microcomputer 1560 (an ID number assigned to each product of the game control microcomputer 1560) stored in a predetermined storage area such as the ROM 54. The numerical data obtained by the execution is set as the initial value of the numerical data updated by the random number circuit 53. By performing such processing, the randomness of the random number generated by the random number circuit 53 can be further improved.

  The game control microcomputer 1560 reads the numerical data as random R from the random number circuit 53 when a start winning to the first start port switch 14a or the second start port switch 15a occurs, and starts to change the special symbol and the effect symbol Sometimes it is determined whether or not to make a big hit display result as a specific display result based on the random R, that is, whether or not to make a big hit. Then, when it is determined to be a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player.

  In addition, the game control microcomputer 1560 is used to input / output (transmit / receive) signals to / from the payout control board 37 (the payout control microcomputer) and the effect control board 80 (the effect control microcomputer) by serial communication. A serial communication circuit 52 is incorporated. The payout control microcomputer and the effect control microcomputer also have a serial communication circuit (not shown) for inputting / outputting signals with the game control microcomputer 1560 through serial communication.

  The RAM 55 is a backup RAM as a non-volatile storage means, part or all of which is backed up by a backup power supply created on the power supply board. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is stored for a predetermined period (until the capacitor as the backup power supply is discharged and the backup power supply cannot be supplied). In particular, at least data corresponding to the game state, that is, the control state of the game control means (such as the value of the special symbol process flag and the pending storage number counter) and data indicating the number of unpaid prize balls (specifically, prize balls described later) The value of the command output counter) is stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, data corresponding to the control state and data indicating the number of unpaid prize balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire RAM 55 is backed up.

  A reset signal from the power supply board is input to the reset terminal of the game control microcomputer 1560. A reset circuit for generating a reset signal supplied to the game control microcomputer 1560 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 1560 and the like become operable, and when the reset signal becomes low level, the game control microcomputer 1560 and the like become inoperative. Therefore, an allowable signal that allows the operation of the game control microcomputer 1560 or the like is output during a period when the reset signal is at a high level, and a game control microcomputer when the reset signal is at a low level. An operation stop signal for stopping the operation of 1560 or the like is output. Note that the reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Furthermore, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 1560. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). Instead of mounting the power monitoring circuit on the power supply board, it may be mounted on a board that is backed up by a backup power supply (for example, the main board 31). In addition, a clear signal indicating that a clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 1560.

  The effect control board 80 includes an effect control CPU 120 (not shown) and an effect control microcomputer (not shown) including a RAM. The RAM may be externally attached. In the effect control board 80, the effect control CPU 120 operates in accordance with a program stored in a built-in or external ROM (not shown), and receives a capture signal (effect) from the main board 31 input via the relay board 77. In response to the control INT signal), an effect control command is received via the input driver and the input port. Also, the effect control CPU 120 (not shown) causes the VDP (video display processor) to perform display control of the effect display device 9 based on the effect control command.

The character ROM is for storing character image data displayed on the effect display device 9, specifically, a person, characters, figures, symbols, etc. (including effect symbols) in advance. The effect control CPU 120 (not shown) outputs the data read from the character ROM to the VDP. The VDP performs display control based on data input from the effect control CPU 120.

  The effect control command and the effect control INT signal are first input to the input driver on the effect control board 80. The input driver allows the signal input from the relay board 77 to pass only in the direction toward the inside of the effect control board 80 (does not pass the signal in the direction from the inside of the effect control board 80 to the relay board 77). It is also a unidirectional circuit as a means.

  As a signal direction regulating means, the signal inputted from the main board 31 is allowed to pass through the relay board 77 only in the direction toward the effect control board 80 (the signal is not passed in the direction from the effect control board 80 to the relay board 77). A unidirectional circuit (not shown) is mounted. For example, a diode or a transistor is used as the unidirectional circuit. Furthermore, since the production control command and the production control INT signal are output from the main board 31 via the I / O port unit which is a unidirectional circuit, the signal going from the relay board 77 to the inside of the main board 31 is restricted. . That is, the signal from the relay board 77 does not enter the inside of the main board 31 (the game control microcomputer 156 side).

  Further, the effect control CPU 120 (not shown) outputs a signal for driving the LED to the lamp driver board 35 via an output port (not shown). Further, the effect control CPU 120 outputs sound number data to the sound control board 70 via the output port.

  In the lamp driver board 35, a signal for driving the LED is input to the LED driver via an input driver (not shown). The LED driver supplies a drive signal to each LED provided on the frame side such as the top frame LED 28a, the left frame LED 28b, and the right frame LED 28c, and each LED provided on the decorative body 301, the wing light emitting modules 400 to 403, and the like.

  In the voice control board 70, the sound number data is input to a voice synthesis IC (not shown) via an input driver (not shown). The voice synthesizing IC generates voice and sound effects corresponding to the sound number data and outputs them to an amplifier circuit (not shown). The amplifier circuit outputs to the speaker 27 an audio signal obtained by amplifying the output level of the voice synthesis IC to a level corresponding to the volume set by the volume. Control data corresponding to sound number data is stored in a sound data ROM (not shown). The control data corresponding to the sound number data is a collection of data showing the output form of the sound effect or sound in a time series in a predetermined period (for example, the changing period of the effect design).

The details of the blade light emitting modules 400 to 403 will be described later.

  Although the decorative body 301 of the present embodiment is configured by a single plate-shaped body having a predetermined plate thickness, the shape can be variously modified and a plurality of individually formed decorative members can be used. It may be configured.

  The cover body 302 is made of a transparent synthetic resin material, and is formed so that the decorative body 301 can be accommodated from the front side in a body portion 311 formed in a box shape having an open front surface. A flange piece 310 for attaching to the game board 6 is formed outward from the peripheral edge of the front opening of the main body 311, and the cover body 302 with respect to the game board 6 is provided on the front side of the flange piece 310.

A gaming component unit 300 is composed of a plurality of gaming components related to the game including 301, the variable display control unit 49, and the like. The gaming component unit 300 configured as described above is detachably attached to the game board 6 and is attached to a cover 302, which is a model-common component used in common for a plurality of models, on a model-specific decorative body. Since various game parts such as 301 and the variable display control unit 49 can be detachably assembled, a plurality of game parts arranged on the back side of the game board 6 can be attached at a time by simply attaching the cover body 302. Not only can it be arranged, but when changing models or performing maintenance, the decorative body and game parts specific to the model can be removed from the cover body 302, so that workability is improved.

  Here, the wing light emitting modules 400 to 403 that are the light guide members of the present invention used in the present embodiment will be described based on FIGS. 6 to 11 by taking the wing light emitting module 400 as an example. The structure of the blade light emitting modules 401 to 403 is the same as that of the blade light emitting module 400.

  As shown in FIG. 6, the wing light emitting module 400 of the present embodiment is mainly a cover that serves as a light guide member of the present invention formed of a transparent acrylic resin formed into a wing shape including a plurality of blades. The lens 430 and the outer surface of the cover lens 430 are provided along the cover lens 430 and each LED for emitting light from the wing light emitting module 400 is surface-mounted. It is mainly composed of an LED substrate 420 and a bottomed box-like substrate case 410 having a predetermined thickness capable of accommodating the LED substrate 420.

  As shown in FIG. 6, the substrate case 410 has an outer shape substantially the same as the outer shape of the cover lens 430, as with the LED substrate 420, and the entire LED substrate 420 can be stored in the case. .

  A plurality of air holes 412 are formed in the bottom portion of the substrate case 410, and the LED substrate 420 accommodated in the substrate case 410 can be radiated by air circulation through the air holes 412. ing.

  In addition to the air holes 412, a screw insertion portion 414 through which a board fixing screw 426 for fixing the LED board 420 is inserted, a guide protrusion 416 for guiding the storage position of the LED board 420 to a predetermined position, and a cover lens 430 are provided. A screw hole 418 for inserting a lens fixing screw 419 to be fixed is provided.

  Note that reference numeral 413 in FIG. 6 denotes a connector opening, and the connection connector 425 provided at the end position of the LED substrate 420 is exposed to the connector opening 413, so that a connection cable is connected to the connection connector 425. The blade light emitting module 400 can be easily connected in the assembled state.

  In addition, a screw for inserting a lens fixing screw 419 inserted into the columnar protrusion 439 while abutting the columnar protrusion 439 formed on the cover lens 430 at the tip end position opposite to the connector opening 413. A stop 415 is provided.

  The thickness of the board case 410 is relatively thin because the wing light emitting module 400 is disposed on the back surface of the game board 6 having a limited arrangement space as described above. In this embodiment, the thickness is about 7 mm.

  As shown in FIG. 6, the LED substrate 420 accommodated in the substrate case 410 includes a horizontal emission type LED 421 that emits monochromatic white light that is visible light in the horizontal direction of the substrate, and a plurality of colors in the vertical direction of the substrate. A vertical emission type LED 422 that emits visible light is surface-mounted, and white light emitted in the horizontal direction from the horizontal emission type LED 421 is incident from each incident portion 432 provided on the cover lens 430 as described later. Thus, the entire cover lens 430 emits white light, and the vertical emission type LED 422 is appropriately lit in each color according to the production, so that the tip portion of the blade constituting the wing emits light in various colors. It has become.

  The LED board 420 has a screw hole 424 through which a board fixing screw 426 for fixing the LED board 420 to the screw insertion part 414 of the board case 410 is inserted, a guide hole 423 through which the tip of the guide protrusion 416 is inserted, Insertion holes 427 and 428 through which the columnar protrusions 439 and 440 provided on the back surface of the cover lens 430 are inserted are provided.

  Although not shown in FIG. 6, other devices such as protective resistors for protecting the horizontal emission LEDs 421 and the vertical emission LEDs 422 from overcurrent are mounted on the LED substrate 420.

  Further, a white resist layer is formed on the surface of the LED substrate 420, and does not affect the white color that is the emission color of the cover lens 430. The amount of light incident on the incident portion 432 can be improved by reflecting and entering the 432.

  The cover lens 430 is formed of an acrylic resin, which is a transparent resin, in the shape of a wing in which a plurality of blades overlap as shown in FIG. 6 by injection molding. 440 is formed.

  Then, after the cover lens 430 is disposed so as to close the opening of the substrate case 410 in which the LED substrate 420 is accommodated and fixed by the substrate fixing screw 426, the screw hole 418 and screw fixing are performed from the back surface of the substrate case 410. The LED board is fixed so that a horizontal emission type LED 421 (described later) mounted on the LED board 420 is at a predetermined position corresponding to the incident part 432 by inserting the lens fixing screw 419 into the part 415 and fixing the cover lens 430. 420, the cover lens 430, and the substrate case 410 are integrated.

  FIG. 7 is a view showing the back surface of the cover lens 430 of the present embodiment. The outer periphery of the cover lens 430 is a flat surface and is in contact with and integrated with the upper end surface of the substrate case 410.

  On the back surface of the cover lens 430, as shown in FIG. 7, a thick wall for guiding light to each part of the blade is formed in a part that becomes a core part of each blade constituting the wing, like a feather bone. A plurality of strip-shaped light guides 431 (see FIG. 8) are provided, and white light, which is visible light emitted from the horizontal radiation type LEDs 421, is placed on the light guides 431 at positions corresponding to the horizontal radiation type LEDs 421. An incident portion 432 for entering the light guide path 431 is provided.

  FIG. 8 is a diagram showing a cross section taken along line AA in FIG. As described above, the cover lens 430 has the shape of a wing formed by a plurality of blades, and each blade forming the wings has a pressure having a predetermined width at the center as shown in FIG. It has a flesh light guide 431, and the cross-sectional view that curves toward the back side of the cover lens 430 from the center toward both sides is an inverted shape. Therefore, the surface of the cover lens 430 having the shape of a wing formed by each of these blades is formed into a wave-like surface by continuously arranging the curved surfaces of the plurality of blades.

  In addition, a large number of narrow grooves 437 are formed in parallel at predetermined intervals on the surface side of the light guide path 431, that is, on the surface of the cover lens 430 so as to be orthogonal to the extending direction of the light guide path 431. The light emitted from the surface of the cover lens 430 is diffused by 437, and the inside of the light guide 431 is guided by reflection on the back side of the light guide 431 as shown in FIGS. A continuous concave portion serving as a light emitting portion of the present invention comprising a plurality of concave portions for radiating a part of light (guided light) to the surface side of the light guide path 431 on the predetermined direction side for emitting light from the surface of the cover lens 430 436 is formed.

  In addition, as described above, the light guided and radiated from the surface side of the light guide 431 by the continuous concave portion 436 is reflected on the curved surface because the surface of the cover lens 430 is curved in an inverted saddle shape. As a result, the entire blade including both ends of the bending portion emits light.

  Next, the structure of the incident part 432 provided in each light guide 431 is demonstrated based on FIG. FIG. 9 is a side sectional view of the light guide 431 cut along a plane parallel to the extending direction of the light guide 431.

  As shown in FIG. 9, the incident portion 432 hangs down substantially in contact with the LED substrate 420 toward the white light emission direction side of the horizontal emission type LED 421 mounted on the surface of the LED substrate 420, and the horizontal emission type LED 421. In addition, a projecting portion having a substantially triangular shape having a slanted side serving as the inclined surface 433 is formed between the nearest concave portion 435 </ b> F which is the concave portion closest to the horizontal emission type LED 421.

  As shown in the enlarged detail view of FIG. 10A, the incident surface 432 ′ facing the horizontal emission LED 421 at the apex portion of the triangle forming the incident portion 432 is adapted to the radiation directivity characteristic of the horizontal emission LED 421. , A concave curved surface surrounding the horizontal emission type LED 421.

  Specifically, the horizontal emission type LED 421 used in this example has a light intensity of 100% when the emission angle is 0 degrees in the horizontal direction as shown in FIG. Since it has a radiation directivity characteristic that the radiation angle is 45 degrees, the light intensity is 50%, the radiation angle is 60 degrees, and the light intensity is 20%, the radiation angle that the light intensity is 20% or more is up to 60 degrees. The incident angle of each light up to 60 degrees of incident light 432 'is approximately 0 degrees so that the light can be incident on the light guide 431 well without being weakened by reflection. Thus, the incident surface 432 ′ is formed in a concave curved surface shape so that the white light emitted from the horizontal emission type LED 421 can be efficiently incident into the light guide path 431.

  In this embodiment, if the acrylic resin forming the incident portion 432 covers the upper position of the horizontal emission type LED 421, particularly the upper part of the light emission position where the light emitting element is provided, the horizontal emission type LED 421 is provided. The heat radiation performance of the horizontal emission type LED 421 is reduced, and there is a possibility that a failure due to overheating, a change in light emission color, or a decrease in lifetime may occur, so that the upper position of the horizontal emission type LED 421 is not covered. However, the present invention is not limited to this, and for example, the LED substrate 420 is disposed along the cover lens 430 as in the present embodiment. As shown in FIG. 10B, in the case where the LED generates little heat as in the case of providing a large number of low output LEDs that generate relatively little heat. The incident surface 432 ′ forming the incident portion 432 covers the upper position of the light emitting portion of the horizontal emission type LED 421 so that almost all of the emitted light emitted from the horizontal emission type LED 421 enters the light guide 431. Anyway.

  Further, a nickel plating layer 434 is formed on the surface of the inclined surface 433, and the inclined surface 433 is mirror-finished by the nickel plating layer 434, and the light incident on the inclined surface 433 is related to the incident angle. Instead, it is almost totally reflected.

  Incidentally, the incident angle a of the light directly radiated and incident on the inclined surface 433 from the horizontal emission LED 421 is the most horizontal of the inclined surface 433 than the incident angle a1 of the light emitted horizontally from the horizontal emission LED 421. The incident angle a2 is the light having the smallest incident angle so that the incident angle a2 of the light emitted at an angle θ1 with respect to the horizontal incident on the position close to the radiation type LED 421 becomes small.

  Therefore, the inclination angle θx formed horizontally with the inclined surface 433 is, as shown in FIG. 11, light having the smallest incident angle among the light emitted directly from the horizontal emission type LED 421 to the inclined surface 433, that is, The incident angle (minimum incident angle a2) of light incident on the inclined surface 433 at a position closest to the horizontal emission type LED 421 and emitted at an angle of θ1 with the horizontal direction is the transparent resin constituting the light guide path 431. A critical angle (R = 42 °) based on an inverse trigonometric function of the ratio of the refractive index of a certain acrylic resin (n1 = 1.49) and the refractive index of air as the surrounding material abutting against the inclined surface 433 (n2 = 1). ), The light emitted from the horizontal emission type LED 421 and directly incident on the inclined surface 433 is totally reflected on the inclined surface 433 and is guided to the light guide path 43. It will be induced inner.

  Specifically, as shown in FIG. 11, since the minimum incident angle a2 is 90− (θ1 + θx) as shown in the equation (1), this relationship is substituted into R <a2 and solved for θx. Since 90-θ1-R (42 °) of the equation (3) is obtained, the horizontal emission type LED 421 is obtained by setting the inclination angle θx formed with the horizontal of the inclined surface 433 to be less than 90-θ1-R (42 °). All of the light emitted from and directly incident on the inclined surface 433 is totally reflected on the inclined surface 433 and guided inside the light guide 431.

  When the horizontal emission type LED 421 is thin and θ1 is almost 0, θx <90−42 = 48, and the inclination angle θx formed horizontally with the inclined surface 433 may be 48 degrees or less. Become.

  Therefore, as in this embodiment, the use of the horizontal emission type LED 421 having a very thin thickness increases the inclination angle θx of the inclined surface 433 by reducing θ1, that is, the length of the inclined surface 433 is further increased. It is possible to shorten the length, and the degree of freedom in designing the light guide 431 can be increased.

  That is, in this embodiment, by providing an inclined surface 433 that connects the apex of the incident portion 432 that is the proximity portion of the horizontal emission LED 421 and the concave top portion of the nearest depression 435F closest to the horizontal emission LED 421, the nearest depression The light of all the optical paths that are directly incident on the 435F from the horizontal emission type LED 421 is incident on the inclined surface 433, and as described above, the inclination angle of the inclined surface 433 is the horizontal emission type on the inclined surface 433. The length of the inclined surface 433 is set so that the light directly incident from the LED 421 has an angle at which all the light is totally reflected.

  By doing so, as shown in FIG. 9B, the light D1 and the light D2, which are light directly incident on the inclined surface 433 from the horizontal emission type LED 421, are totally reflected by the inclined surface 433 and guided. At the surface side interface of the optical path 431, total reflection is performed toward a region Z from a point P1 closest to the horizontal emission type LED 421 to a point P2 farthest from the horizontal emission type LED 421 (D1 ′, D2 ′).

  On the other hand, as shown in FIG. 10C, when the inclined surface 433 of the present invention is not provided, the high-intensity radiated light emitted from the horizontal emission type LED 421 is directly incident on the nearest concave portion 435F. Since the light is emitted to the surface side of the light guide 431, the light emission intensity of the portion corresponding to the nearest concave portion 435F is remarkably increased, and good light emission of the cover lens 430 ′ cannot be obtained.

  Further, in addition to the light directly incident from the horizontal emission type LED 421, when the incident portion 432 is provided in the middle of the light guide path 431, the inclined surface 433 is guided through the light guide path 431. The light (guide light) that reaches the portion 432 is also incident, but the inclined surface 433 is at an angle that allows total reflection of light that is directly incident from the horizontal emission type LED 421, so that the guide light is transmitted from the inclined surface 433. Even if the angle is such that the light is radiated to the back side of the light guide 431, the nickel plating layer 434 is provided on the inclined surface 433, so that the guided light is transferred from the inclined surface 433 to the back side of the light guide 431. Since it can be prevented from being emitted, these guided lights can be used efficiently without wasting them.

  In this embodiment, the surface side interface of the light guide 431 in these regions Z is set to an angle that increases the incident angle of light incident on the surface side interface of the region Z as shown in FIG. Thus, more of the light incident on the surface side interface is totally reflected and guided to the continuous recess 436. That is, the surface-side interface angle of the region Z is an angle that guides the strong reflected light that is totally reflected by the inclined surface 433 incident on the region Z to the continuous recess 436.

  Note that these angles are not limited to the present embodiment, and the surface side interface angle of the region Z is the light totally reflected by the inclined surface 433 incident on the region Z into the continuous recess 436. Any angle that can be guided is acceptable.

  Of the light incident from the horizontal emission type LED 421 in the light guide 431, the light having a predetermined angle and entering the nearest recess 435F or the continuous recess 436, for example, the light D3, is reflected by the nearest recess 435F. By being guided toward the front surface side of the light guide path 431, the light emitted directly from the horizontal emission type LED 421 is emitted from the front-side interface of the light guide path 431 so that the nearest concave portion 435F and the continuous concave portion 436 are emitted. Instead, light is emitted by the guided light in the light guide 431.

  As described above, according to the above-described embodiment, the inclined surface 433 serving as the linear advancement preventing portion is provided on the linear path between the incident portion 432 and the nearest concave portion 435F. Since direct incidence can be prevented, even if the cover lens 430, which is a light guide member, is thin, the light emission intensity by the nearest recess 435F near the entrance 432 is farther than the nearest recess 435F. It can be avoided that the light emission intensity is significantly higher than that of the other concave portion forming the portion.

  In addition, according to the above embodiment, the structure of the straight line travel preventing part can be simplified by setting the straight line travel preventing part as the inclined surface 433, and all the light in any optical path that travels straight to the nearest concave part 435F is slanted. Since the light is totally reflected by the surface and guided in the light guide path 431, the light that travels straight to the nearest concave portion 435F can be effectively used for light emission of the continuous concave portion 436 serving as the light emitting portion.

  In the present embodiment, the inclined surface 433 is illustrated as the straight line travel prevention portion, but the present invention is not limited to this, and for example, an inclined surface is provided as shown in FIG. In the configuration shown in FIG. 10C, a light scattering plate 444 is arranged as a linear travel prevention member at a predetermined angle between the incident portion 432 and the nearest recess 435F, and the light traveling directly to the nearest recess 435F is transmitted. The cover lens 445 may be configured to prevent high-intensity light emitted from the horizontal emission type LED 421 from directly entering the nearest concave portion 435F by being diffused.

  In addition, according to the embodiment, by providing the nickel plating layer 434 on the inclined surface 433, light other than light that is incident from the incident portion 432 and linearly travels to the nearest concave portion 435F, for example, the light guide 431 is guided. Since the guided light can be prevented from being radiated to the outside of the light guide 431 from the inclined surface 433, visible light guided in the light guide 431 is emitted to the surface of the cover lens 430 serving as a light emitting unit. Furthermore, it can be used effectively.

  In the above embodiment, the plating layer is nickel plating that can be easily formed as electroless plating on an acrylic resin. However, the present invention is not limited to this, and the type of plating reflects light well. Any metal can be used.

  Moreover, in the said Example, although these metal layers are formed by plating, this invention is not limited to this, These metal layers are methods other than plating, for example, vacuum evaporation, foil transfer, etc. You may form by.

  Further, according to the embodiment, by providing the LED substrate 420 along the cover lens 430 serving as a light guide member, as described above, by using a plurality of LEDs, each LED generates less heat. In addition, since the horizontal emission type LED 421 serving as a light emitter can be disposed at an appropriate position of the cover lens 430 to shorten the length of the light guide 431, visible light that guides the inside of the light guide 431 can be obtained. However, the present invention is not limited to this, and the cover can be provided without providing these LED substrates 420. You may make it provide the board | substrate which has arrange | positioned LED, such as horizontal emission type LED421, only in the outer peripheral part of the lens 430. FIG.

  Further, according to the embodiment, since the incident surface 432 ′ is formed in a concave curved surface surrounding the horizontal emission type LED 421, the incident angle of the visible light emitted from the horizontal emission type LED 421 to the incident surface 432 ′ is substantially 0. Therefore, the amount of visible light reflected by the incident surface 432 ′ can be reduced, and the visible light emitted from the horizontal emission type LED 421 can be efficiently incident from the incident unit 432. .

  Further, according to the embodiment, the angle of the region Z is such that the incident angle of the reflected lights D1 ′ and D2 ′ totally reflected by the inclined surface 433 incident on the surface side interface of the region Z becomes large. Therefore, since the reflected lights D1 ′ and D2 ′ are surely guided to the continuous recess 436, the visible light that has entered the light guide 431 is emitted to the surface of the cover lens 430 that serves as the light emitting part. Furthermore, it can be used effectively.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, the angle of the inclined surface 433 is an angle that totally reflects all the light that directly enters the inclined surface 433 from the horizontal emission type LED 421, but the present invention is not limited to this. When the nickel plating layer 434 is provided on the inclined surface 433, light incident on the inclined surface 433 is reflected by the nickel plating layer 434. Therefore, the length of the inclined surface 433 is shortened so that the angle of the inclined surface 433 is increased. It is good also as an angle which does not totally reflect.

  Moreover, in the said Example, although acrylic resin is illustrated as a transparent member used as the material of the cover lens 430, this invention is not limited to this, Transparent resin other than these acrylic resins, for example, polycarbonate resin Alternatively, a simple substance such as a polyester resin or a silicone resin, or a composite alloy may be used.

  Moreover, in the said Example, although horizontal emission type LED421 is illustrated as a light-emitting body, this invention is not limited to this, For example, as shown in FIG.12 (b), vertical light emission type LED450 is shown. May be used.

  That is, as shown in FIG. 12B, a sub-board 420 ′ on which a vertical light emitting type LED 450 is mounted is provided upright on the LED board 420 with a connector or the like, and visible light emitted from the LED 450 is converted into a cover lens. In this case, since the angle θ1 is increased, the inclination angle θx of the inclined surface 433 ′ is decreased and the inclined surface 433 ′ is increased. In order to prevent the length of the substrate from becoming longer, a plating layer 434 ′ is provided on the inclined surface 433 ′, or the angle of the portion of the inclined surface 433 ′ close to the LED substrate 420 is reduced so as to be closer to the horizontal. It is preferable to do.

  Moreover, in the said Example, although the form which used the surrounding substance of the inclined surface 433 as air was illustrated, this invention is not limited to this, As a surrounding substance of these inclined surfaces 433, for example, wing light emission In order to prevent interference between the cover lens 430 and the LED substrate 420 due to the operation of the module 400, a silicone gel or the like capable of absorbing vibration is provided between the cover lens 430 and the LED substrate 420. In this case, the surrounding material that contacts the inclined surface 433 is the silicone gel, and the angle θx of the inclined surface 433 may be determined based on the critical angle based on the ratio to the refractive index of the silicone gel.
