<< Basic operation of gaming machine >>
Next, the basic operation of the gaming machine 100 will be described. The gaming machine 100 acquires special figure determination information when the first or second start condition is satisfied, and performs special figure determination based on the special figure determination information. Acquisition of special figure determination information corresponds to acquisition of special figure determination right. The special figure determination includes determination of whether or not the jackpot has been won (whether or not the jackpot has been won or lost). In addition, the winning of the jackpot may be expressed as the occurrence of the jackpot (the same applies to the jackpot described later). In addition, the fact that a certain special figure determination information is won in a jackpot may be expressed as the special figure determination information is a big hit (the same applies to a small hit described later). When the special figure determination is performed based on the special figure determination information acquired by the establishment of the first and second start conditions, the gaming machine 100 displays the first and second special symbols variably for a predetermined time, respectively. The first and second special symbols are stopped and displayed in a manner showing the result of the special figure determination.

  When the gaming machine 100 displays the special symbol (first or second special symbol) in a variable manner, the gaming machine 100 displays the decorative symbol in a variable manner on the image display unit 104, and stops the decorative symbol in accordance with the stop display of the special symbol. Display. The decorative symbols displayed on the image display unit 104 include first to third decorative symbols, and each decorative symbol is associated with a numerical value or a symbol. For example, if a special symbol is stopped and displayed in a manner showing a big hit when a big hit occurs, the first to third decorative symbols are displayed in a manner showing a big hit (for example, a so-called doublet such as “7, 7, 7”). To stop display. At this time, the combination of the first to third decorative symbols that are stopped and displayed may differ depending on the type of jackpot that has occurred. When the result of the special figure determination is a loss (that is, when the jackpot is not won), the first to third decorative symbols are stopped at, for example, a so-called scatter pattern indicating a loss. The loose eye refers to a state in which two or three of the first to third decorative symbols are non-common symbols.

  When the special symbol is stopped and displayed in a manner indicating a jackpot, the gaming machine 100 enters a jackpot gaming state. In the jackpot game state, a jackpot game is executed in which a round game that opens the jackpot 111 is executed for a round (for example, 16 rounds) according to the type of the jackpot that has been won. When a game ball wins the big prize opening 111 while the big prize opening 111 is opened, the gaming machine 100 pays out a predetermined number of prize balls. The jackpot game state ends when the jackpot game ends. Games that involve the opening of the big prize opening 111 (including a big hit game and may include a small prize game described later) are given a chance to obtain a prize ball by winning a game ball at the big prize opening 111. It can be said that it is more advantageous for the player than a game that does not involve opening the mouth 111 (for example, a game in a normal gaming state). The advantage here means that the player can easily obtain more prize balls (the expected value of the prize balls to be obtained is large) as the special winning opening 111 is opened.

  Special figure determination is not performed during the jackpot game. In the jackpot game state, the game is played by right-handed. “Right hit” means that a game ball is launched into a game area on the right side of the center line that divides the game area 103 left and right in the game area 103. On the other hand, left-handed strike means that a game ball is launched into the game area on the left side of the center line in the game area 103. In the left-handed game board 101 is formed so that a game ball can be won at the first start opening 105 but a game ball cannot be won at the second start opening 106 and the big winning opening 111. Has been. The game board 101 is formed so that a game ball can be won at the second starting port 106 and the big winning port 111, but a game ball cannot be won at the first starting port 105 by right-handed. Has been. The gate 108 is a right region in the game region 103 and is disposed above the special winning opening 111. Therefore, in the left strike, the game ball cannot pass through the gate 108, and only the right hit game ball can pass through the gate 108.

  After the jackpot game ends, the gaming machine 100 returns to a state in which special figure determination is performed. At this time, the gaming state of the gaming machine 100 can be changed.

<< Game state of gaming machine >>
The gaming machine 100 has a low probability non-power support game state (normal game state), a low probability power support game state, and a high probability non-power except for game states (including a jackpot game state) that are associated with the opening of the big prize opening 111. Any of the support game state and the high probability electric support game state may be taken. The gaming state in the initial state of the gaming machine 100 is a low probability non-electric support game state. By using the RAM clear switch provided on the back of the gaming board 101 to initialize the gaming information of the gaming machine 100, the gaming machine 100 enters an initial state.

  The low probability non-electric support game state and the low probability electric support game state belong to the low probability game state. The high probability non-electric support game state and the high probability electric support game state belong to the high probability game state. The probability that it is determined that the jackpot is won in the special figure determination is higher in the high probability gaming state than in the low probability gaming state. Therefore, the high probability gaming state is more advantageous to the player than the low probability gaming state with respect to the likelihood of winning the jackpot (ease of playing the jackpot game).

  The low probability electric support game state and the high probability electric support game state belong to the electric support game state. In the electric support game state, the gaming machine 100 provides a game support function (hereinafter referred to as “electric support”) that involves opening and closing the electric tulip 107 (that is, the electric support is activated). When the electric support is given, compared with the time when it is not so, the fluctuation time of the normal symbol is shortened, the winning probability per common figure in the common figure determination (and therefore, the opening frequency of the electric tulip 107 is increased), and The opening time of the electric tulip 107 is increased, and as a result, in the electric support game state, it becomes easier for the game ball to win the second start port 106 than in the non-electric support game state where no electric support is given. In the electric support game state, a game is performed by the above-mentioned right strike, and the trigger for the special figure determination is mainly a winning to the second start opening 106.

  The low probability non-electric support game state and the high probability non-electric support game state belong to a non-electric support game state to which no electric support is given. In the non-electric support game state, the game is performed by left-handed as described above, and the trigger for the special figure determination is mainly a winning to the first start opening 105. As understood from the above description, the electric support game state is a game state in which the start condition (second start condition) is more easily established than the non-electric support game state. Therefore, the electric support game state is more advantageous to the player than the non-electric support game state with respect to the ease of establishment of the start condition.

In addition, a priority order for receiving special figure determination is set for each special figure determination information stored in the storage area 413a. Basically, a higher priority is set for the special figure determination information acquired earlier in time. However, it is assumed that a higher priority is set for the special figure determination information acquired when the second start condition is satisfied as compared to the special figure determination information acquired when the first start condition is satisfied. The prior determination process executed in the start port switch process will be described later.

  In the gate switch process, the main CPU 411 obtains the count values of the counters C4 and C5 at the timing when the passing of the game ball to the gate 108 is detected, and uses the obtained count values of the counters C4 and C5 as a random number and a common number per figure. The common figure determination information included as a symbol random number is stored in the general figure determination information storage area 413b. The storage area 413b can store general-purpose determination information with a predetermined number as an upper limit. Here, it is assumed that the predetermined number is four. The number of general-purpose determination information in the storage area 413b corresponds to the hold information number U3. A priority order for receiving the common figure determination is set for each piece of common figure determination information stored in the storage area 413b. A higher priority is set for the information for determining ordinary drawings acquired earlier in time.

  In the big prize opening switch process, the main CPU 411 detects a game ball won in the big prize opening 111 by the big prize opening SW416. In the normal winning opening switch process, the main CPU 411 detects a game ball won in the normal winning opening 112 by the normal winning opening SW417.

[1-2-3. Special design processing]
In the special symbol process, the main CPU 411 acquires, as the determination target TT, the special figure determination information set with the highest priority among the special figure determination information stored in the special figure determination information storage area 413a. The special figure determination is executed for the determination target TT. At this time, the special figure determination information that is the determination target TT is deleted from the storage area 413a. The special figure determination includes a special figure determination, a special symbol determination, and a special fluctuation pattern determination. Then, in the special symbol processing, after the special symbol variation display is performed for the variation time indicated by the special symbol variation pattern selected by the special symbol variation pattern determination, the determination result per special symbol and the determination result of the special symbol determination are shown. To stop the special symbol. The result of the special figure determination can be stored in the main RAM 413. In the special symbol processing, when the special symbol determination information is not stored in the storage area 413a, the special symbol processing is finished without performing the special symbol determination. Also, the special symbol determination is not performed when the special symbol is displayed in a variable manner or when a game involving the opening of the special winning opening 111 is performed.

  When the main CPU 411 starts the variation display of the special symbol, the main CPU 411 instructs the production control unit 403 to start the execution of the variation effect by setting the variation start command including the result of the special symbol determination in the main RAM 413. When the change is stopped, a change stop command is set in the main RAM 413 to instruct the effect control unit 403 to end the execution of the change effect. These commands set in the RAM 413 are output to the effect control unit 403 in an output process (see FIG. 5) described later.

  With reference to FIG. 6, determination per special figure is performed using a special figure determination table TAt including a low probability special figure determination table TAt1 and a high probability special figure determination table TAt2. Each of the tables TAt1 and TAt2 has a predetermined determination value associated with the jackpot. When the high probability game flag is set to OFF at the time of determination per special figure, the main CPU 411 makes a determination per special figure using the table TAt1, and when the high probability game flag is set to ON. Determination per special figure is performed using the table TAt2. Then, the main CPU 411 determines that the jackpot has been won if the random number per special figure of the determination target TT matches the determination value associated with the jackpot, otherwise it is a loss (that is, the jackpot is won) Not). The gaming state of the gaming machine 100 is a high probability gaming state when the high probability gaming flag is ON, and a low probability gaming state when the high probability gaming flag is OFF. Here, it is determined per special figure so that the winning probability of winning the jackpot (that is, the probability determined to play the jackpot game) is 1/300 and 1/30 in the low probability gaming state and the high probability gaming state, respectively. Assume that a table TAt is formed.

  In addition, the gaming machine 100 may be formed so that a small hit can occur, and in this case, the main CPU 411 also determines a small hit in the special figure determination. The small hit is not a big hit, but is a specific lose represented by a special symbol in a mode different from a normal lose (a loss other than the small hit). The main CPU 411 determines that the winning unit is won when the random number per special figure of the determination target TT matches the determination value associated with the small unit. For example, it is possible to reduce the winning probability per unit to 1/300 without depending on ON / OFF of the high probability game flag.

  In the special symbol determination, the main CPU 411 compares the special symbol determination table TZt with the special symbol random number of the determination target TT, and determines in which symbol the special symbol is stopped based on the comparison result. . There are a plurality of types of jackpots, and when the jackpot is won, the jackpot type is determined based on the comparison result.

  In the special figure fluctuation pattern determination, the special figure fluctuation pattern for the determination target TT is determined based on the special figure fluctuation pattern table THt and the random number per special figure, the special symbol random number, and the special figure fluctuation pattern random number of the determination target TT. The determination of the special figure fluctuation pattern is synonymous with the selection or setting of the special figure fluctuation pattern. The special figure fluctuation pattern table THt includes a plurality of special figure fluctuation patterns, and one special figure fluctuation pattern for the determination target TT is selected in the special figure fluctuation pattern determination. Each special symbol variation pattern defines a variation pattern of a special symbol, and defines, for example, a variation time of the special symbol (the length of time during which the variation display of the special symbol is performed).

[Pre-judgment process in start-up switch process]
Further, the main CPU 411 executes a pre-determination process during the start port switch process (see FIG. 5). In the pre-determination process, the main CPU 411 sets, as a pre-determination target, the special-determination determination information that is stored in the special-determination determination information storage area 413a and is put on hold, and the pre-determination target is determined per special figure. The special symbol design determination and the special symbol variation pattern determination are sequentially executed. The methods of the per-special determination, the special symbol design determination, and the special-figure variation pattern determination for the prior determination target (these determinations are collectively referred to as prior determination) are the same as those for the determination target TT. The result of the prior determination is stored in the main RAM 413. The result of the prior determination is included in a hold increase command (also referred to as a prior determination command), the hold increase command is set in the main RAM 413, and is transmitted to the effect control unit 403 in an output process described later. The holding increase command includes information indicating which of the holding information numbers U1 and U2 has increased in addition to the result of the prior determination. The pre-determination process for certain special figure determination information is executed in the start-up switch process before the special figure determination information is acquired and stored in the storage area 413a. Therefore, the prior determination for any special figure determination information is executed before the special figure determination is executed for the special figure determination information.

[1-2-4. Normal symbol processing]
The normal symbol processing (see FIG. 5) will be described. In the normal symbol processing, the main CPU 411 obtains the information for determining the common figure set with the highest priority in the general-purpose information storage area 413b as the general-purpose determination target FF, and determines the general-purpose determination in the main ROM 412. Based on the table and the FF for which the normal pattern is determined, a general pattern determination consisting of a general pattern determination, a general symbol determination, and a general pattern variation pattern determination is executed. Display stop display. The information for determining the normal map that has become the target FF for normal map determination is deleted from the storage area 413b. In the normal symbol process, when the general pattern determination information is not stored in the storage area 413b, the normal symbol process is terminated without performing the general symbol determination. Further, the normal symbol determination is not performed when the normal symbol variation display is performed and when the game (auxiliary game) for opening the electric tulip 107 is performed. In the determination per common figure, it is determined whether or not the winning per common figure is won. When winning per common figure, the type per common figure is determined by the universal symbol determination. There are two types of per map: per long open and short open. The time for the electric tulip 107 to be in the open state is longer per long opening than per short opening. The main CPU 411 displays the variation of the normal symbol for the variation time based on the result of the normal pattern variation pattern determination, and then stops and displays the normal symbol in a manner showing the result of the normal symbol hit determination and the general symbol determination.

[1-2-5. Electric accessory control processing]
In the electric accessory control process (see FIG. 5), the big prize opening process and the electric chew process are sequentially executed. In the special winning a prize opening process, when the result of the special figure determination indicates that a big win is won, the special winning opening 111 is opened and closed using a big winning opening opening pattern corresponding to the type of the big win. In the big prize opening pattern table DKt, a big prize opening pattern defining the opening mode of the big prize opening 111 is stored for each type of jackpot. When the gaming machine 100 is configured so that a small winning can occur, the big winning opening opening pattern for the small winning is also stored in the big winning opening pattern table DKt, and the result of the special figure determination shows the winning of the small winning When the player wins, the special winning opening 111 is opened and closed using the small winning special winning opening opening pattern. The main CPU 411 realizes the big prize opening process with reference to the table DKt.

  The jackpot game with the opening of the big winning opening 111 is started after the special symbol is stopped and displayed in a manner showing the jackpot. In the jackpot game, until the opening time of the big winning opening 111 reaches a predetermined maximum opening time (predetermined time; for example, 30 seconds) or until the number of winning game balls to the big winning opening 111 reaches a predetermined value (for example, ten). A round game that opens the grand prize winning hole 111 is executed Rmax times with a predetermined interval period (in other words, an interval time). Therefore, it can be considered that the jackpot game includes round games for Rmax. Rmax represents the number of rounds according to the type of jackpot. When a predetermined ending period (in other words, ending time; for example, 5 seconds) elapses after the last round game ends, the game state returns to a state in which special figure determination can be performed.

  In addition, the game state setting process (see FIG. 5) is executed in the big prize opening process during the jackpot game or after the jackpot game. In the game state setting process, the main CPU 411 sets the state of various game flags stored in the main RAM 413 including the high probability game flag and the electric support game flag. As described above, the gaming state of the gaming machine 100 is a high probability gaming state when the high probability gaming flag is ON, and a low probability gaming state when the high probability gaming flag is OFF. The gaming state of the gaming machine 100 is an electric support game state when the electric support game flag is ON, and a non-electric support game state when the electric support game flag is OFF. In the game state setting process during the big prize opening process that is executed in response to the occurrence of the jackpot, the high-probability game flag and the electric support game flag are turned on according to the game state at the time of the jackpot occurrence or the type of jackpot that has occurred / OFF is set, and a high probability game remaining number X indicating the remaining number of fluctuations of the special symbol in which the high probability gaming state is maintained and an electric number indicating the remaining number of fluctuations in the special symbol in which the electric support game state is maintained. The number of remaining support games J is set in the main RAM 413.

  The high probability remaining game count X set in the game state setting process is subtracted by “1” every time the special figure determination is executed when “X ≧ 1”, and becomes “X = 0”. The high probability game flag is set to OFF, and the gaming state of the gaming machine 100 becomes a low probability gaming state. The electric support game remaining number J set in the game state setting process is decremented by “1” every time the special figure determination is executed when “J ≧ 1”, and becomes “J = 0”. The electric support game flag is set to OFF, and the gaming state of the gaming machine 100 becomes a non-electric support game state. However, after J = 1 is changed to J = 0 by execution of the special figure determination, the electric support game state is maintained until the special symbol is stopped and displayed in a manner indicating the result of the special figure determination, and the stop display is performed. A non-electric support game state can be set later. In the initial state of the gaming machine 100, the high probability game flag and the electric support game flag are OFF, and “0” is set to the number of times X and J.

  In addition, even when winning a small win, a game with the opening of the big winning opening 111 (this is called a small hit game) is executed, but the main control unit 401 is triggered by the winning of the small winning Do not change the gaming state (probability of winning the jackpot and whether or not to give power support). In other words, the gaming state of the gaming machine 100 (the jackpot winning probability and the presence / absence of electric support) does not change between before and after the small win. In the small hit game, for example, the opening of the special winning opening 111 with a short opening time (for example, 0.2 seconds) is repeated a plurality of times.

  In the electric Chu process, the main CPU 411 opens and closes the electric tulip 107 based on the result of the common map determination. In the case of winning per usual figure, the electric tulip 107 is opened for a predetermined time.

[1-2-6. Prize ball processing]
In the winning ball process, the main CPU 411 pays out a predetermined number of winning balls for winning at the first starting port 105, the second starting port 106, the big winning port 111, and the normal winning port 112. Is set in the main RAM 413 as a prize ball command.

[1-2-7. Output processing]
In the output process, the main CPU 411 stores information (including the above-described commands) stored in the main RAM 413, etc., in each control unit (prize ball control unit 402 and effect control unit 403) connected to the main control unit 401. Output). A command related to the prize ball is output to the prize ball control unit 402, and a command related to the effect is output to the effect control unit 403. In the output process, the main CPU 411 may transmit arbitrary information recognized or held by itself (for example, information indicating the state of the electric support game flag and the high probability game flag) to the effect control unit 403. When the output process ends, the timer interrupt process also ends. When the timer interrupt process ends, the process executed by the main CPU 411 returns to the main process (see FIG. 5).

  As shown in FIG. 4, a board external information terminal board 491 is connected to the main control section 401, and the main control section 401 sends information indicating the contents stored in the main RAM 413 to the outside (through the board 491). For example, it can be output to a hall computer of a game facility.

[2. Prize ball control unit]
The prize ball control unit 402 (see FIG. 4) includes a CPU, a ROM, and a RAM. Based on a payout instruction (prize ball command) from the main control unit 401, the prize ball is paid out using the payout unit 429. Do. Various SWs for detecting a game ball are connected to the prize ball control unit 402. Specifically, as shown in FIG. 4, the prize ball control unit 402 includes a fixed position detection SW 424 that detects a game ball at a predetermined position, a payout ball detection SW425 that detects a game ball that has been paid out, A ball presence detection SW 426 for detecting whether or not there is a game ball and a full tank detection SW 427 for detecting that the upper plate 123 and the lower plate 125 are filled with game balls are connected. A detection signal indicating the result is sent to the prize ball control unit 402. The winning ball control unit 402 pays out a winning ball or stops paying out a winning ball based on a payout instruction output from the main control unit 401 or a detection signal input from the SWs 424 to 427. Further, the prize ball control unit 402 may output detection signals from the SWs 424 to 427 to the main control unit 401.

  Further, a launching unit 428 is connected to the prize ball control unit 402. The award ball control unit 402 detects the operation of launching a game ball with respect to the launch unit 428 (operation by the player) and controls the launch of the game ball. The launcher 428 launches a game ball for a game, and includes a sensor that detects a game operation by the player, a solenoid that launches the game ball, and the like. When the prize ball control unit 402 detects a game operation by the sensor of the launch unit 428, the game ball 103 is intermittently fired by driving a solenoid or the like in response to the detected game operation, and the game area 103 of the game board 101 is played. Launch a game ball. The prize ball controller 402 is connected to a frame external information terminal board 492, and various information handled by the prize ball controller 402 can be output to the outside through the board 492.

[3. Production control unit]
The effect control unit 403 includes a sub CPU 431, a sub ROM 432, and a sub RAM 433 (see FIG. 4). The effect control unit 403 is an image / audio control unit (not shown) that performs display control of the image display unit 104 and audio output control of the speaker unit 115, and lighting control of the effect light unit 116 and the board lamp 135 on the game board 101. In addition, a lamp control unit (not shown) that performs drive control of the movable frame accessory 117 and the movable board accessory 130 is provided. As described above, the speaker unit 115 includes the speakers 115L, 115C, and 115R, the effect light unit 116 includes the left frame light 116L, the center frame light 116C, and the right frame light 116R, and the panel movable accessory 130 is the shutter accessory 130a. And an arm-shaped accessory 130b. In addition, the effect control unit 403 is connected to an effect button unit 121 and an operation key 122 for receiving an operation from a player. The effect control unit 403 can perform an effect corresponding to the input operation content from the player for the effect button part 121 and the operation key 122. As described above, the effect button unit 121 includes the left long button 121L, the center button 121C, and the right long button 121R.

  The effect control unit 403 realizes an arbitrary effect including a change effect using an effect realizing element (effect means). That is, the production control unit 403 controls the production realization element to cause the production realization element to perform a desired production (the main body of the production in this expression is the production realization element, but in the description of this embodiment, The effect control unit 403 is regarded as the main subject of the effect). The effect realization elements include all or part of the image display unit 104, the speaker unit 115, the effect light unit 116, the movable frame accessory 117, the effect button unit 121, the panel lamp 135, and the movable panel accessory 130. The variation effect indicates an effect executed by the effect control unit 403 during the variation display of the special symbol, and includes an effect suggesting a determination result of the special symbol determination. It can also be understood that the effect executed by the effect control unit 403 at the start of the special symbol change or at the end of the special symbol change is also included in the change effect. It should be noted that suggestions, notifications, notifications, notifications, etc. due to effects may be considered to be for players unless otherwise specified. Unless otherwise specified, the display of an arbitrary image and design (decorative design, etc.) under the control of the effect control unit 403 refers to the display on the image display unit 104, and the output of sound and sound is from the speaker unit 115. Refers to the output of sound.

  FIG. 7 lists the main processes performed by the effect control unit 403. When power is supplied to the effect control unit 403, the effect main process is executed by the sub CPU 431. In the effect main process, initial setting of various devices in the effect control unit 403 is performed and the setting result is stored in the sub RAM 433. The sub CPU 431 interrupts and executes the effect timer interrupt process for the effect main process at the cycle set in the effect main process. In the effect timer interrupt process, the sub CPU 431 sequentially executes an effect random number update process, a command reception process, and an operation reception process.

  The effect control unit 403 is provided with an effect random number counter that counts effect random numbers. In the effect random number update process, an effect random number is added by adding “1” to the count value of the effect random number counter. Update the count value of the counter. In the effect random number counter, when the count value exceeds a predetermined upper limit value, the count value is returned to “0”, and thereafter the same count up is performed. The count value of the effect random number counter can be referred to as the value of the effect random number used in various effects.

  In the command reception process, the sub CPU 431 executes a special drawing effect process, a general drawing effect process, and a hit effect process.

  The special figure effect process includes an effect start process and an effect end process. The sub CPU 431 starts the variation effect by executing the effect start process in response to the reception of the variation start command from the main control unit 401, and then performs the effect in response to the reception of the variation stop command from the main control unit 401. The variation effect is ended by executing the end process. The effect start process includes a variable effect content determination process. In the variation effect content determination process, the sub CPU 431 determines the content of the variation effect based on the effect random number, the command received from the main control unit 401, or the like. Specifically, for example, a variation effect pattern table (special drawing variation effect pattern table) including a plurality of variation effect patterns (special drawing variation effect pattern) each defining the contents of the variation effect is stored in the sub ROM 432 in advance. In the variation effect content determination process, the content of the variation effect is determined by selecting and determining one variation effect pattern from the variation effect pattern table based on the variation start command or the like.

  Further, when receiving a hold increase command from the main control unit 401, the sub CPU 431 stores information based on the hold increase command in the sub RAM 433 and performs a hold increase process in the command reception process. In the hold increase process, a hold image corresponding to the prior determination target is additionally displayed on the image display unit 104. The reserved image corresponding to the advance determination target is later deleted from the image display unit 104 or shifted to a specific display position when the change start command is received when the advance determination target becomes the determination target TT. . The sub CPU 431 can also perform a pre-reading notice effect for the prior determination target based on the hold increase command.

  The ordinary drawing effect process (see FIG. 7) is executed by the sub CPU 431 when a command related to a normal symbol is received from the main control unit 401. A command related to the normal symbol is transmitted from the main control unit 401 to the effect control unit 403 at the start and end of the variation of the normal symbol. In the ordinary drawing effect process, the ordinary drawing effect is executed when the normal symbol changes.

  The winning effect process (see FIG. 7) is executed by the sub CPU 431 when a command related to the winning effect is received from the main control unit 401. That is, for example, when a special symbol and a decorative symbol are stopped and displayed in a manner in which the determination target TT has won a jackpot or a jackpot and indicates a jackpot or a jackpot, a command related to a win effect is sent from the main control unit 401 to the effect control unit. The sub CPU 431 executes a win effect to be performed during the big hit game or the small hit game based on the reception result of the command.

  In the operation accepting process (see FIG. 7), the sub CPU 431 operates based on a signal from the effect button unit 121 or the operation key 122 to the player on the operation button unit 121 or the operation key 122 (operation presence / absence and operation input). ). The effect control unit 403 can perform an effect according to the recognized operation state.

<< type of jackpot >>
FIG. 8 is a diagram showing jackpot types assumed in the present embodiment. In this embodiment, there are special A, special B, special A, special C, special D, and special B as jackpot types. The number of rounds for special A, special A, special C, and special B is 8, and the number of rounds for special B and special D is 16. The larger the number of rounds, the more the number of award balls that can be obtained by winning in the big winning opening 111 in the jackpot game, which is more advantageous to the player. Therefore, each jackpot game of Special B and Special D is more advantageous to the player than each jackpot game of Special A, Special C, A and B. In the judgment per special figure for the first special symbol (in the judgment per special figure based on the establishment of the first starting condition), when the jackpot is won, the ratio that the jackpot becomes Special A, Special B, and A They are 60%, 5%, and 35%, respectively. In the special symbol hit determination for the first special symbol, no special C, special D, or big B jackpot will occur. In the judgment per special figure for the second special symbol (in the judgment per special figure based on the establishment of the second starting condition), when the jackpot is won, the ratio that the jackpot becomes special C, special D, and B is These are 30%, 35%, and 35%, respectively. In the special symbol hit determination for the second special symbol, no special A, special B, or big A big hit will occur. The special symbol design determination table TZt is formed so that the type of jackpot for the first and second special symbols is determined at the above-described ratio.

  After the jackpot game of any of Special A to Special D is completed, the main CPU 411 sets the gaming state of the gaming machine 100 to the high probability electric support game state, and then the next jackpot (that is, from the jackpot that occurred immediately before). If the number of times the special symbol fluctuates (that is, the number of times the special symbol has been fluctuated and stopped through the variable display) is equal to or greater than the number of times of high probability and the number of times of electric support is granted, the gaming machine 100 Is set to the low probability non-electric support game state.

The high-probability number of times refers to the number of changes in the special symbol that maintains the high-probability gaming state. In other words, for a certain jackpot, after the jackpot game is over, while the special symbol fluctuates by i _k times, the gaming state becomes a high probability gaming state, and after the special symbol fluctuates by i _k times, the low probability gaming state when it is a high probability granted number corresponding to the jackpot is i _k times (i _k is an integer). Since a big hit is more likely to occur in the high probability gaming state than in the low probability gaming state, the higher the number of high probability grants, the more advantageous for the player.
The number of times when the electric support is given refers to the number of times the special symbol is maintained to maintain the electric support game state. That relates to certain jackpot, after completion of the jackpot gaming, non conductive support game after while, the and special symbol is gaming state and conductive support gaming state fluctuates by i _d times the special symbol is varied by i _d times when it is a state, support grant number electrostatic corresponding to the jackpot is i _d times (i _d is an integer). Since the starting condition is more easily established in the electric support game state than in the non-electric support game state, the more the number of electric support grants, the more advantageous for the player.

  The number of high-probability grants and power support grants for the jackpots of Special A to Special D are both 10,000 (see FIG. 8). Therefore, after the special jackpot game of any one of special A to special D is finished, when the number of times the special symbol fluctuates reaches 10,000 without any other big hits (in other words, when the special figure judgment is performed 10,000 times). ), The gaming state of the gaming machine 100 is shifted from the high probability electric support game state to the low probability non-electric support game state. However, since the jackpot winning probability in the high-probability gaming state is “1/30”, after the jackpot game of any one of Special A to Special D is completed, the probability of winning the next jackpot is substantially high. It can be said that the sapo game state is maintained.

  After the end of the big hit game of A or B, the main CPU 411 sets the gaming state of the gaming machine 100 to the low probability electric support game state until the special symbol fluctuates by a predetermined number of times of the electric support grant, and the special symbol After that, the gaming state of the gaming machine 100 is set to the low-probability non-electrical support state (that is, the normal gaming state). However, if the next jackpot is won after the end of the A or B jackpot game, the gaming state after the end of the next jackpot game is set according to the type of the jackpot won next time. For example, if the special A jackpot is won at the first variation of the special symbol after the end of the bonus game of A or B, the gaming state of the gaming machine 100 is highly probable after the end of the bonus game of the special A. It is set to the electric support game state. The number of times electric support is given to the jackpots of A and B is 20 times. In addition, after the big hit game of tsu A or tsu B, since it is not a high probability gaming state but a low probability electric support game state, the high probability grant count for the jackpot of tsu A and tsu B is 0 times. .

In the game state setting process associated with special A, special B, special C or special D jackpot, both the high probability game flag and the electric support game flag are turned ON, and the high probability game remaining number X and the electric support game remaining number J are set. In both cases, “10000” is set.
In the game state setting process associated with the big hit of A or B, the high probability game flag is turned OFF while the electric support game flag is turned ON and the high probability game remaining number X is set to “0”. As a result, “20” is set in the remaining electric support game number J.
That is, the high probability remaining game count X and the electric support game remaining count J set in the game state setting process executed with a certain jackpot are respectively the high probability grant count and the electric support grant corresponding to the jackpot. This is consistent with the number of times (see FIG. 8).

  As can be seen from FIG. 8, the special symbol determination based on the establishment of the second start condition is relatively more advantageous to the player than the special symbol determination based on the establishment of the first start condition (ie, more Easy to get many prize balls). Here, “relatively advantageous” means that the expected value of the number of winning balls obtained by winning the big winning opening 111 in the jackpot game executed based on the establishment of the second starting condition is executed based on the establishment of the first starting condition. This means that the number of prize balls obtained by winning the winning prize 111 in the jackpot game is larger than the expected value. “Expected value of the number of winning balls obtained by winning the jackpot game 111 in the jackpot game” is the expected value of the number of rounds in the jackpot game or the maximum value of the total opening time of the jackpot 111 in the jackpot game It may be read as a value.

(First embodiment)
A first embodiment of the gaming machine 100 according to the present invention will be described.

  FIG. 9 is a schematic front view of the board disposed in the center frame light 116C. In the gaming machine 100 according to the present invention, the center frame light 116C, the left frame light 116L, and the right frame light 116R have the same configuration. doing. Therefore, in the following description, the center frame light 116C will be described as an example on behalf of the light unit 116. It should be noted that the upper, lower, left, and right of the substrate 6 below refer to the upper, lower, left, and right of the state shown in FIG. 9 unless otherwise specified. That is, the longitudinal direction of the substrate 6 is the left-right direction, and the short side direction is the up-down direction. Unless otherwise specified, the front surface refers to the surface of the substrate in the state shown in FIG. 9 that is visible to the player, and the back surface refers to the surface opposite to the front surface.

<< Substrate structure >>
As shown in FIG. 9, the center frame light 116 </ b> C has a substrate 6 and an LED chip 7 mounted on the substrate 6.

  As shown in FIG. 10, the substrate 6 includes a base 61, a conductive layer 62 provided on the surface of the base 61, and a cover layer 63 that covers the conductive layer 62. The substrate 61 is a thin plate of an insulating resin such as polyimide. The substrate 61 is a material having flexibility and has flexibility. The conductive layer 62 is a metal layer such as copper or aluminum. The conductive layer 62 is formed on the surface of the substrate 61 using a film forming method such as physical or chemical vapor deposition or sputtering. Further, since the conductive layer 62 is a metal layer, it is less likely to bend than the base material 61.

  The substrate 6 is a double-sided substrate in which conductive layers 62 are formed on both the front and back surfaces. The conductive layer 62 is patterned to supply a drive signal to an electronic component such as the LED chip 7. That is, the conductive layer 62 is a so-called wiring pattern. The conductive layer 62 includes a signal wiring 621 for supplying a driving signal to the electronic component and a ground wiring 622 that is grounded. The signal wiring 621 includes a power supply wiring for supplying power.

  The substrate 6 is provided with a through hole 64 that penetrates the base material 61 and the conductive layer 62. A layer having the same conductivity as that of the conductive layer 62 is formed on the inner peripheral surface of the through hole 64. By providing a conductive layer on the inner peripheral surface of the through hole 64, the conductive layer 62 formed on the front and back of the insulating base 61 is electrically connected. The through holes 64 electrically connect the signal wirings 621 to which corresponding signals are supplied or the ground wirings 622.

  The cover layer 63 is an insulating film that covers the substrate 61 and the conductive layer 62. The cover layer 63 is also formed of a flexible material like the base material 61. By providing the cover layer 63, the conductive layer 62 is protected. For example, the conductive layer 62 can be prevented from being damaged even if it comes into contact with a metal member such as a sheet metal or a screw used in the gaming machine 100. It is also possible to suppress electricity such as static electricity from flowing to the conductive layer 62. There is a portion where the cover layer 63 is not formed so that part of the signal wiring 621 and the ground wiring 622 is exposed to the outside. The portions of the signal wiring 621 and the ground wiring 622 exposed from the cover layer 63 are terminal portions 651 (652) that connect the connection portions of the electronic components.

  On the substrate 6, electronic components are surface-mounted. That is, the electronic component is connected to the signal wiring 621 and the ground wiring 622 by bringing the connection portion of the electronic component into contact with the terminal portion and soldering from the contacted side.

<< About LED chip >>
The LED chip 7 is a light emitting diode in which a semiconductor capable of emitting light of each wavelength of R (red), G (green), and B (blue) is made into one chip. The LED chip 7 includes a rectangular parallelepiped package 70 which is an exterior body. Inside the package 70, an element that emits R light (referred to as an R element), an element that emits G light (referred to as a G element), and an element that emits B light (not shown) (not shown) B element). The LED chip 7 includes an anode connection portion 71 (71r, 71g, 71b) and a cathode connection portion 72 (72r, 72g, 72b) connected to each of the R element, the G element, and the B element. Have. The anode connection portion 71 and the cathode connection portion 72 protrude from the opposite surfaces of the side surfaces of the package 70.

  Each element of the LED chip 7 emits light when a current is passed from the anode to the cathode. That is, each element of the LED chip 7 emits light when a voltage that causes a current necessary for light emission to flow between the anode and the cathode is applied. Therefore, the anode connecting portions 71 (71r, 71g, 71b) are connected to different signal wirings 621 (621r, 621g, 621b), respectively. Further, in order to pass a current from the anode to the cathode, the cathode connection portion 72 (72r, 72g, 72b) is connected to the ground wiring 622 (622r, 622g, 622b).

  The center frame lamp 116C emits light toward the player. Therefore, in the center frame lamp 116C, the LED chip 7 is mounted on the front surface 6fa of the substrate 6, that is, the lower surface in FIG. The light emission of the LED chip 7 is controlled by current. The center frame lamp 116C includes a control chip Cnt for controlling the LED chip 7 and a resistor R for adjusting a current supplied to the LED chip 7. The control chip Cnt is a driver circuit that is controlled by the effect control unit 403 and causes the LED chip 7 determined by the timing, emission color, and luminance based on the control of the effect control unit 403 to emit light.

  In many cases, packages of electronic components such as the control chip Cnt and the resistor R are black or a color close to black. If such a black or substantially black component is mounted on the same surface as the LED chip 7, when light is emitted from the LED chip 7, luminance unevenness is caused. Therefore, electronic components other than the LED chip 7 are mounted on the back surface 6ta of the substrate 6. The cover layer 63 covering the front surface 6fa of the substrate 6 is white with high light reflectance. That is, the cover layer 63 also serves as a reflecting member that reflects the light emitted to the substrate 6 out of the light emitted from the LED chip 7 forward.

  On the other hand, since the back surface 6ta does not need to reflect light, the cover layer 63 may be a color other than white. That is, the color may absorb light to some extent. In the present embodiment, the back surface 6ta is also provided with a white cover layer, like the front surface 6fa. By using the same cover layer for the front surface 6fa and the back surface 6ta, the material can be shared and the manufacturing process can be simplified, so that the cost can be reduced.

  As shown in FIG. 9, the substrate 6 is provided with a first region 601 and a second region 602. The first area 601 is an area where electronic components such as the LED chip 7, the control chip Cnt, and the resistor R are mounted. The substrate 6 includes three first regions 601. The first region 601 is provided at both ends in the center and in the longitudinal direction, as shown in FIG. In the following description, the first region may be described as the first region 601C at the center, the first region 601R on the right side, and the first region 601L on the left side in FIG. In the present embodiment, the substrate 6 includes three first regions 601, but is not limited thereto. For example, the number of first regions may be two, or four or more first regions 601 may be provided.

  As shown in FIG. 9, the board | substrate 6 has the 2nd area | region 602 between the 1st area | regions 601 in front view. That is, the second area 602 connects between the first areas 601. In the substrate 6 shown in FIG. 9, the second region 602 is a region where electronic components such as the LED chip 7, the control chip Cnt, and the resistor R are not mounted. However, the present invention is not limited to this, and an electronic component may be mounted in the second region 602.

  In the substrate 6 of this embodiment, the second region 602 is located between the central first region 601C and the left first region 601L, and between the central first region 601C and the right first region 601R. Is provided. The substrate 6 includes two second regions 602. In the following description, the second region 602 may be described as the left second region 602L and the right second region 602R in FIG.

  The first area 601 and the second area 602 will be described. The front surface 6fa side of the first region 601 is a region where the LED chip 7 is mounted. On the front surface 6fa side of the first region 601, a signal wiring 621 for supplying a drive signal to the anode connection portions 71r, 71g, 71b of the LED chip 7 is provided. The cathode connection parts 72r, 72g, 72b are connected to a grounded wiring pattern. The resistance of the conductive layer 62 decreases as the area increases. Therefore, in the first region 601, ground wiring 622 that is insulated from these wirings is provided in portions other than the signal wiring 621 (including the power supply wiring) that transmits the drive signal to the LED chip 7. Note that on the back surface 6ta side of the substrate 6, electronic components other than the LED chip 7, here, the control chip Cnt and the resistor R are mounted on the surface. In the first region 601, the signal wiring 621 and the ground wiring 622 that is the conductive layer 62 that covers most of the portion other than the gap that insulates the wiring also serve as a shield for shielding electromagnetic waves.

  On the front surface 6fa side and the back surface 6ta side of the first region 601, a signal wiring 621 and a ground wiring 622 are formed at portions other than the gap for insulating the wirings. The front surface 6fa side and the back surface 6ta side of the first region 601 are covered with the conductive layer 62, that is, substantially the entire portion excluding the gap that insulates the wires. Note that, in each of the central first region 601C, the right first region 601R, and the left first region 601L, the conductive layer 62 covers almost the entire front side 6fa side and the back side 6ta side.

  A large number of LED chips 7 are mounted on the center frame lamp 116C. A connector (not shown) to which wiring for transmitting an effect control signal from the effect control unit 403 is connected is connected to the first region 601R on the right side. The wiring that transmits the effect control signal also serves as grounding of the substrate 6. A control chip Cnt for controlling the LED chip 7 mounted on the substrate 6 is mounted in the first region 601R on the right side. Based on the effect control signal from the effect control unit 403, the control chip Cnt transmits a drive signal for lighting the LED chip 7 mounted in the first region 601R on the right side with the determined lighting timing, emission color, and luminance. To do.

  The LED chip 7 is mounted on the first region 601R on the right side, and is also mounted on the first region 601C in the center and the first region 601L on the left side. That is, it is necessary to transmit the drive signal from the control chip Cnt mounted in the first region 601R to the LED chip 7 mounted in the central first region 601C and the left first region 601L. Therefore, the signal wiring 621 and the ground wiring 622 are provided in the second region 602. The signal wiring 621 and the ground wiring 622 are provided on both the front surface 6fa side and the back surface 6ta side of the second region 602R on the right side.

  As shown in FIG. 9, the signal wiring 621 in the second region 602R on the right side only needs to be able to transmit a drive signal necessary for driving the LED chip 7 from the first region 601R on the right side to the first region 601C in the center. If the thickness of the signal wiring 621 is constant, the resistance varies depending on the area. When the area decreases, the resistance increases and the drive signal may not be transmitted. Therefore, the signal wiring 621 provided in the second region 602R on the right side has a minimum area that can reliably transmit the drive signal. Note that although the area of the signal wiring 621 is the minimum necessary area, it is not limited to this. However, a small area is preferred.

  In the second region 602 on the right side, the signal wiring 621 extends along the arrangement direction of the first region 601 and the second region 602. In the second region 602R on the right side, the ground wiring 622 reduces the wiring resistance when driving the LED chip 7 mounted on the first region 601C in the center and the LED chip 7 mounted on the first region 601L on the left side. It is the minimum area which can suppress and carry out the grounding of cathode connection part 72r, 72g, 72b reliably. The area of the ground wiring 622 is the minimum necessary area, but is not limited to this. However, a small area is preferred.

  Similarly, the left second region 602L includes a signal wiring 621 having a minimum area necessary for transmitting a drive signal transmitted from the central first region 601C to the left first region 601L. Note that although the area of the signal wiring 622 is the minimum necessary area, it is not limited to this. However, a small area is preferred.

  Similarly, in the left second region 602L, the ground wiring 622 suppresses the wiring resistance when driving the LED chip 7 mounted in the left first region 601L, and the LED mounted in the left first region 601L. The chip 7 has a minimum area capable of reliably grounding the cathode connection portions 72r, 72g, and 72b of the chip 7. The area of the ground wiring 622 is the minimum necessary area, but is not limited to this. However, a small area is preferred. The signal wiring 621 and the ground wiring 622 are provided on both the front surface 6fa side and the back surface 6ta side of the left second region 602L.

  In the second region 602 including the second region 602R on the right side and the second region 602L on the left side, the area ratio of the metal layer 62 to the entire surface of the second region 602 by the signal wiring 621 and the ground wiring 622 is small.

  That is, the second region 602 is provided with a portion where the conductive layer 62 is formed on the base material 61 and a portion where the conductive layer 62 is not formed. The cover layer 63 covers the upper surfaces of the portion where the conductive layer 62 is formed and the portion where the conductive layer 62 is not formed.

  As described above, since the base material 61 and the cover layer 63 are materials having flexibility, they are easily bent (easily deformed). On the other hand, since the conductive layer 62 is a metal layer, it is difficult to bend (not easily deformed). In the substrate 6, the area ratio of the conductive layer 62 on the entire surface of the first region 601 is larger than the area ratio of the conductive layer 62 on the entire surface of the second region 602. For this reason, the second region 602 is more easily bent than the first region 601.

  The width (vertical width) of the signal wiring 621 in the second region 602 may be thicker, thinner, or the same as the width of the signal wiring 621 provided in the first region 601. May be.

  FIG. 11 is a schematic plan view showing the inside of the box-shaped body 140. FIG. 11 shows the substrate 6 included in the center frame light 116C. In FIG. 11, the lower side in the figure is the player side, that is, the front side. As shown in FIG. 11, a fixing portion 141 for fixing the substrate 6 is provided inside the box-shaped body 140. The substrate 6 is fixed in a state where the substrate 6 is bent backward in front of the fixing portion 141, that is, in a state where the left and right ends of the substrate 6 are bent backward. In addition, a translucent cover 142 is attached in front of the fixing portion 141 so as to cover the substrate 6. In FIG. 11, although not shown, a speaker 115C and a speaker box that accommodates the speaker 115C are arranged inside the box-shaped body 140.

  In the substrate 6, first, the central first region 601 </ b> C is fixed to the fixing portion 141. The central first region 601C is fixed to the boss 143 protruding from the fixing portion 141 by screwing. Note that the fixing method is not limited to screwing, and a method that can firmly fix the substrate 6 so as not to be displaced can be widely adopted.

  After fixing the central first region 601C, the right end and the left end are moved to the rear, and the right first region 601R and the left first region 601L are respectively corresponding parts of the fixing unit 141. To fix. The first region 601R on the right side and the first region 601L on the left side are also fixed to the boss 143 protruding from the fixing portion 141 by screws. The left and right ends of the substrate 6 run rearward, and a bending stress acts on the substrate 6.

  The substrate 6 includes a second region 602 in which the area ratio of the conductive layer 62 is lower than that of the first region 601 on which components such as the LED chip 7, the control chip Cnt, and the resistor R are mounted. When the substrate 6 is bent so that the first region 601R on the right side and the first region 601L on the left side face each other, the stress due to the bending is concentrated in the second region 602, and the second region 602 It is greatly deformed as compared with one region 601.

  When the portion of the substrate 6 where the conductive layer 62 is formed is bent, the conductive layer 62 is easily peeled off from the base material 61 due to the bending. When the conductive layer 62 is peeled, adjacent wirings come into contact with each other, and it becomes difficult to accurately transmit the drive signal, and the LED chip 7 does not emit light accurately. The peeling of the conductive layer 62 is more likely to occur as the width in the direction intersecting the bending line when the substrate 6 is bent is narrower. That is, when the substrate 6 is bent in the direction shown in FIG. 11, the wiring with a narrow width in the left-right direction is easily peeled off by bending.

  In the second region 602, both the signal wiring 621 and the ground wiring 622 extend left and right in the diagram shown in FIG. That is, the wiring extends in a direction intersecting the bending line, and the conductive layer 62 hardly peels off in the second region 602.

  As described above, it is possible to suppress peeling of the conductive layer by using the substrate provided with the first region where the component is mounted and the second region where the area ratio of the conductive layer is smaller than that of the first region. . By using the substrate 6 for the central frame lamp 116C that is mounted in a curved manner, it is possible to turn on the plurality of LED chips 7 accurately according to the control of the effect control hand portion 403, and to improve the interest of the game by the effect. It is possible.

(Second embodiment)
As described above, the substrate 6 includes the first region 601 in which the conductive layer 62 is formed on the substantially entire surface and the second region 602 in which the minimum necessary conductive layer 62 is formed, so that the bending stress is applied to the second region 602. Thus, the second region 602 is greatly deformed. In other words, deformation of the first region 601 is suppressed. On the other hand, as described above, when the substrate 6 is bent and attached, the first region 601 is less likely to bend than the second region 602, but is not bent at all, and is slightly bent.

  When the electronic component is surface-mounted on the substrate, if the substrate is bent, stress may be applied to the connection portion between the connection portion of the electronic component and the terminal portion, and the connection portion may be detached from the terminal portion. In the center frame light 116 </ b> C, the direction of the LED chip 7 is adjusted to prevent the connection part of the LED chip 7 from dropping from the terminal part of the substrate 6 even if the first region 601 is bent. Below, the attachment direction to the board | substrate 6 of the LED chip 7 is demonstrated with reference to drawings.

  FIG. 12 is a front view showing a part of the substrate 6 on which the LED chip 7 is mounted. As described above, the LED chip 7 includes the anode connection portions 71r, 71g, 71b and the cathode connection portions 72r, 72g, 72b connected to the package 70, the R element, the G element, and the B element, respectively. Have. The anode connecting portions 71r, 71g, 71b and the cathode connecting portions 72r, 72g, 72b protrude from the package 70.

  As shown in FIG. 12, the package 70 has a square shape when viewed from the front. The anode connection portions 71r, 71g, 71b protrude from the side surface corresponding to one side in the front view of the package 70. The anode connecting portions 71r, 71g, 71b are arranged at equal intervals. Further, the cathode connection portions 72r, 72g, 72b protrude from the surface opposite to the surface where the anode connection portions 71r, 71g, 71b of the package 70 are arranged. The cathode connection parts 72r, 72g, 72b are arranged side by side at equal intervals.

  The anode connection parts 71r, 71g, 71b are connected to different signal wirings 621r, 621g, 621b via different terminal parts 651r, 651g, 651b, respectively. Further, in order to allow current to flow from the anode to the cathode, the cathode connecting portions 72r, 72g, and 72b are connected to different ground wirings 622r, 622g, and 622b through different terminal portions 652r, 652g, and 652b, respectively. The terminal portions 651r, 651g, and 651b and the terminal portions 652r, 652g, and 652b may be collectively referred to as a terminal portion group 65 in some cases.

  That is, in the first region 601 of the substrate 6, the terminal portion group 65 for connecting the connection portions 71r, 71g, 71b, 72r, 72g, 72b of the LED chip 7 to the wirings 621r, 621g, 621b, 622r, 622g, 622b, respectively. Is provided.

  As shown in FIG. 13, among the terminal group 65, the terminal portions 651r, 651g, 651b are arranged on a straight line in the longitudinal direction of the substrate 6, that is, the direction along the curve when the substrate 6 is bent. . Further, in the terminal portion group 65, the terminal portions 652r, 652g, and 652b are also arranged in a straight line in the longitudinal direction of the substrate 6, that is, the direction along the curve when the substrate 6 is bent. The terminal portions 651r, 651g, and 651b and the terminal portions 652r, 652g, and 652b are arranged in parallel. Note that the direction along the curve is a direction coinciding with the circumferential direction of the curved surface when viewed from the center of curvature of the curved substrate 6. For example, in the substrate shown in FIG.

  The portion where the connecting portion 71r and the terminal portion 651r are in contact, the portion where the connecting portion 71b and the terminal portion 651b are in contact, the portion where the connecting portion 72b and the terminal portion 652b are in contact, and the portion where the connecting portion 72r and the terminal portion 652r are in contact are lined in order. When connected with, the line becomes a rectangle. That is, the above-mentioned part becomes each vertex of a rectangle. A line connecting the terminal portions 651r and 651b is the short side L1, and a line connecting the terminal portion 651r and the terminal portion 652r is the long side L2.

  When the LED chip 7 is mounted on the curved substrate 6, the substrate 6 is the highest position protruding most at the center portion of the package 70, and is a rectangular shape surrounded by the portion where the connection portion and the terminal portion are in contact with each other. The vertex is at the lowest position. That is, the distortion between the central portion of the rectangle and the vertex of the rectangle is the largest. Assuming that the curvature of the first region 601 when the substrate 6 is attached is constant, the shorter the distance from the vertex to the center, the smaller the strain. The smaller the strain is, the smaller the stress for peeling the connection part from the terminal part is. In summary, when the first region 601 is curved, the LED chip 7 is mounted so that the long side L1 is in the bending direction so that the rectangular short side L2 is parallel to the bending direction. As compared with the case where the LED chip 7 is mounted so as to be parallel to each other, the connection portion is less likely to peel off from the terminal portion.

  That is, in the substrate 6, the plurality of terminal portions 651 r, 651 g, 651 b and the terminal portions 652 r, 652 g, 652 b included in the terminal portion group 65 are arranged along the direction in which the substrate 6 bends, thereby The stress acting on the connecting portions 71r, 71g, 71b, 72r, 72g, 72b is reduced, and the LED chip 7 is difficult to peel off from the substrate.

  By attaching the LED chip 7 to the substrate 6 having such a configuration, the LED chip 7 can be made to emit light with accurate timing, emission color, and luminance in accordance with the control of the effect control unit 403. Thereby, it is possible to improve the interest of the game by production.

  In this embodiment, the terminal portions 651r, 651g, 651b and the terminal portions 652r, 652g, 652b included in the terminal portion group 65 are arranged in a direction parallel to the direction along the curve. It is not limited. For example, if the terminal portions 651r, 651g, 651b and the terminal portions 652r, 652g, 652b are arranged in order along the curve, an angle is given to the direction along the curve, that is, parallel to the direction along the curve. Not necessarily. Thus, even when the angle is relative to the direction along the curve, if the terminal portions are arranged side by side in the direction along the curve, compared to the case where the terminals are arranged perpendicular to the direction along the curve, The connection part of the LED chip 7 has an effect that it is difficult to peel off from the terminal part.

(Third embodiment)

  FIG. 14 is a front view of a board used in the gaming machine according to the present invention. A substrate 6B shown in FIG. 14 has the same configuration as the substrate 6 of the first embodiment except that the second region is different. That is, the substrate 6B is used in place of the substrate 6 in the center frame lamp 116C. For this reason, in the substrate 6B, substantially the same parts as those of the substrate 6 are denoted by the same reference numerals, and detailed description of the same parts is omitted. The direction indicated by the vertical and horizontal directions is the same as in the first embodiment.

  A substrate 6B shown in FIG. 14 is provided with a first region 601 and a second region 603. The configuration of the second area 603 is the same as that of the second area 602. In other words, the second region 603 includes a portion where the minimum necessary conductive layer 62 (the signal wiring 621 and the ground wiring 622) is formed and a portion where the conductive layer 62 is not formed.

  As shown in FIG. 14, a notch 6031 is provided at the end of the second region 603 in the vertical direction. A through hole 6032 is provided in a portion of the second region 603 where the conductive layer 62 is not provided. Since the notch 6031 and the through hole 6032 are provided in the second region 603, the second region 603 is more easily bent than the second region 602. Thereby, when bending the board | substrate 6B, a bending stress becomes easy to concentrate on the 2nd area | region 603. FIG.

  From the above, the bending (deformation) of the first region 601 can be suppressed when the substrate 6B is bent. And while suppressing peeling of the conductive layer 62, it can suppress that the connection part and terminal part of an electronic component containing the LED chip 7 become non-conducting.

(Fourth embodiment)

  FIG. 15 is a cross-sectional view of a substrate used in the gaming machine according to the present invention. A substrate 6C shown in FIG. 15 is used in place of the substrate 6 in the center frame lamp 116C. Therefore, in the substrate 6C, the same reference numerals are given to substantially the same portions as those of the substrate 6, and detailed description of the same portions is omitted. The substrate 6C corresponds to the substrate 6, and the first region 604 corresponds to the first region 601 in the substrate 6C. The second region 605 corresponds to the second region 602 in the substrate 6C.

  As shown in FIG. 15, the substrate 6 </ b> C is a substrate in which two base materials 61 are stacked, and has a configuration in which a conductive layer 62 is sandwiched between the two base materials 61. That is, the substrate 6C is a so-called multilayer substrate. In addition, it is called lamination | stacking that a base material, a conductive layer, and a cover layer are arranged in the thickness direction of a board | substrate.

  The substrate 6C is provided with a first region 604 and a second region 605. The first region 604 and the second region 605 are arranged side by side in the longitudinal direction of the substrate 6C in front view.

  In the first region 604 of the substrate 6C, the conductive layer 62 is formed between the two base materials 61, and the conductive layer 62 is also formed on the outer surface of each of the two base materials 61. . Further, a cover layer 63 is formed on the outside thereof. By providing the conductive layer 62 between the two base materials 61, the substrate 6C can increase the number of wirings compared to the substrate 6 including the single base material 61. Thereby, the area of the substrate can be reduced. Further, by forming the signal wiring 621 for transmitting the drive signal to the electronic component in the conductive layer 62 sandwiched between the base materials 61, there is physical contact of other members on the outside of the substrate 6C, or due to static electricity or the like. Even if there is a discharge, the signal wiring 621 is hardly damaged or the drive signal is not easily disturbed.

  In the substrate 6 </ b> C, in the second region 605, there is one base 61, and the conductive layer 62 and the cover layer 63 are provided on both the front and back surfaces of the base 61. Note that the conductive layer 62 in the second region 605 has a necessary minimum or substantially minimum size in terms of area ratio, like the second region 602 of the substrate 6. In addition, in the second region 605, the number of metal layers 62 is reduced by reducing the number of base materials 61. That is, in the first region 604, the conductive layer 62 is a total of three layers between the two base materials 61 and the outside of each base material 61. On the other hand, in the second region 605, one conductive layer 62 in total is formed on the front and back of the base material 61.

  In the substrate 6 </ b> C, since the number of layers of the base material 61 and the conductive layer 62 is small, the second region 605 is more easily bent than the first region 604. Bending stress concentrates in the second region 605 when the left and right ends of the substrate 6C are bent so as to face each other. Thereby, the bending (deformation) of the first region 604 can be suppressed. In addition, by providing a notch, a through-hole, etc. like the board | substrate 6B, it is possible to concentrate bending stress on the 2nd area | region 605 further, and to further suppress the bending of the 1st area | region 604. FIG.

  By using the substrate 6C for the central frame lamp 116C that is mounted in a curved manner, the plurality of LED chips 7 can be accurately turned on according to the control of the effect control hand portion 403, and the interest of the game by the effect is improved. It is possible.

  In each of the above-described embodiments, the LED chip 7 is described as an example of the electronic component, but the present invention is not limited to this. For example, the present invention can be widely applied to a terminal group to which an electronic component having a configuration in which connection portions are arranged side by side on a surface facing a package, for example, a DIP (Dual Inline Package) electronic component. Further, the terminal portion group is not limited to the terminal portion group on which the DIP electronic component is mounted, and the terminal portion is arranged along the curve in the terminal portion group to which the electronic component having the configuration in which the connection portion is arranged in a straight line is connected. By doing so, it is possible to obtain the same effect. In addition, when attaching the electronic component of the package in which the outer wall is formed in a curved surface shape, the terminal portions may be arranged on a curve in accordance with the curve. Moreover, you may arrange in a linear form by adjusting the area of a terminal part.

<< Consideration of Invention >>
Consider the invention embodied in the embodiments described above.

  ◇ A gaming machine 100 according to one aspect of the present invention includes a substrate 6 including a base 61 and a conductive layer 62 disposed on the surface of the base 61, and the substrate 6 includes a plurality of components mounted thereon. A first region 601 and a second region 602 connecting between the first regions 601, wherein the area ratio of the conductive layer 62 to the base material 61 in the second region 602 is based on the conductive layer 62 in the first region 601. The area ratio relative to the material 61 is small.

  By doing so, in the substrate 6, the bending rigidity of the second region 602 is lower than the bending rigidity of the first region 601. As a result, bending stress concentrates in the second region 602 when a force is applied to the substrate 6 to bend the opposite ends. Therefore, the bending of the first region 601 is smaller than the bending of the second region 602. That is, the deformation of the first region 601 is suppressed by the deformation of the second region 602.

  The first region 601 is provided with more conductive layers 62 than the second region 602, that is, the signal wiring 621 and the ground wiring 622. In addition, components such as the LED chip 7 are also mounted in the first region 601. The deformation of the first region 601 is suppressed by the deformation of the second region 602, so that problems such as separation, disconnection, and short circuit of the signal wiring 621 and the ground wiring 622 are less likely to occur.

  The gaming machine 100 according to one aspect of the present invention includes a portion where the conductive layer 62 is not formed in the second region 602.

  By doing so, it is possible to reduce the bending rigidity of the second region 602, and bending stress when a force is applied to the substrate so as to oppose both ends concentrates on the second region 602. It becomes easy to do.

  A gaming machine 100 according to one aspect of the present invention includes a substrate 6 that can be attached in a curved state, and the substrate 6 includes a conductive layer 62 formed on a surface of a base material 61, the conductive layer 62 being A terminal part including a plurality of terminal parts 651r, 651g, 651b, 652r, 652g, 652b to which a plurality of connection parts 71r, 71g, 71b, 72r, 72g, 72b protruding from the package of the electronic component 7 are respectively fixed. A plurality of terminal portions 651r, 651g, 651b (652r, 652g, 652b) of the terminal portion group 65 are arranged in a direction along the curvature of the substrate 6;

  Thus, by arranging the terminal portions 651r, 651g, 651b along the curve, the terminal portions 651r, 651g, 651b and the terminal portions 651r, 651g, 651b and The length in the direction along the curve of the connecting portion with the connecting portions 71r, 71g, 71b can be shortened. Thereby, the displacement difference of the thickness direction of the board | substrate 6 with the terminal parts 651r, 651g, 651b and the connection parts 71r, 71g, 71b by the bending of the board | substrate 6 can be made small. Thereby, the stress which the connection parts 71r, 71g, 71b tends to remove from the terminal parts 651r, 651g, 651b can be reduced. Further, for the same reason, the terminal portions 652r, 652g, and 652b and the connection portions 72r, 72g, and 72b have a small displacement difference, so that the connection portions 72r, 72g, and 72b may be disconnected from the terminal portions 652r, 652g, and 652b. It is possible to reduce the stress. Thereby, even if the board | substrate 6 is bent and arrange | positioned, the electronic component 7 cannot separate | separate from the board | substrate 6 easily.

  In the gaming machine 100 according to one aspect of the present invention, the substrate 6 includes a plurality of first regions 601 and a second region 602 that connects the first regions 601 and has a lower bending rigidity than the first region 601. , And the terminal portion group 65 is provided in the first region 601.

  Since the bending rigidity of the second region 602 is lower than the bending rigidity of the first region 601, bending stress concentrates in the second region 602 when a bending force is applied to the substrate 6 so that the end faces the substrate 6. Thereby, the deformation of the second region 602 is larger than that of the first region 601. That is, the second region 602 is greatly deformed, so that the deformation of the first region 601 is suppressed. By providing the terminal group 65 in the first region 601, the electronic component 7 is mounted in the first region 601. Since the deformation of the first region 601 is suppressed by the deformation of the second region, the stress applied to the electronic component 7 (the connection portions 71r, 71g, 71b, 72r, 72g, 72b) mounted in the first region 601 is also reduced. Is done. For this reason, it is possible to suppress problems such as the connection portions 71r, 71g, 71b, 72r, 72g, 72b of the electronic component 7 coming off or being broken due to an excessive force.
