Operation control means for operating each of the first movable member and the second movable member in a predetermined manner,
The operation control means includes
By operating either or both of the first movable member and the second movable member,
A first state in which the first detected part and the second detected part overlap each other between the light emitting element and the light receiving element;
A second state in which one of the first detected part and the second detected part exists between the light emitting element and the light receiving element;
Between the light emitting element and the light receiving element, it is possible to switch between the first state to be detected and the third state in which neither the second detected part is present,
The detection means includes
Different signals are output in each of the first state, the second state, and the third state.

  According to the present invention, based on the difference between the light transmittance of two detected portions and the light transmittance of one detected portion, between the light emitting element and the light receiving element of the detecting means, A first state where two detected parts exist, a second state where one detected part exists, and a third state where no detected part exists are determined. be able to. Thus, the state of the two movable members (whether they are alone at a predetermined position or superimposed on the predetermined position) can be detected by one detection means.

In addition, the gaming machine of the present invention,
The detection means is characterized in that an output voltage changes in each of the first state, the second state, and the third state.

  Thereby, based on the change of the output voltage of a detection means, the state of two movable members can be detected easily.

  According to the configuration of the present invention described above, it is possible to detect the states of a plurality of movable members with one detection means.

  The first start port 28a is configured as a fixed start port in which the size of the game ball receiving port does not change and the possibility of entering the game ball is constant, and the game ball can always be entered. ing. On the other hand, the second start port 28b is a so-called tulip type and has a pair of wing pieces on the left and right, and the upper end gap between the pair of wing pieces serves as a game ball receiving port. The pair of wing pieces are each opened and closed by tilting in the left-right direction. With this opening and closing action, the second start port 28b is the size of the game ball receiving port of the pair of wing pieces. It is configured as a variable starter that changes. The second start port 28b is in an open state with a high probability of entering by opening a pair of blade pieces, and in a normal state with a low possibility of entering by closing a pair of blade pieces (incoming balls) Including an impossible closed state). When the normal symbol is stopped and displayed as a combination of symbols, the pair of wing pieces are opened to expand the game ball receiving port of the second start port 28b, and the second start port 28b is a normal electric accessory. Function as.

  Inside the start port 28, there are a start port entrance detection switch 28s (see FIG. 9) for detecting the entrance of a game ball into the first start port 28a, and the entrance of the game ball into the second start port 28b. A start opening ball detection switch 28t (see FIG. 9) for detection and a start opening solenoid 28c (see FIG. 9) for operating the pair of blade pieces are provided. When the pair of wing pieces are opened to the left and right, the size of the game ball receiving port of the second start port 28b is enlarged from the normal time, and the second start port 28b has a possibility of entering a game ball. It becomes an open state that becomes larger. On the other hand, when the pair of wing pieces are erected, the size of the game ball receiving port of the second start port 28b is slightly larger than the diameter of the game ball (one game ball can pass). The second start port 28b is in a normal state (closed state) in which the possibility of entering a game ball is reduced (or entry is impossible). When a game ball enters one of the start ports 28a and 28b, a special symbol (to be described later) starts to be displayed in a variable manner.

  The big prize device 33 is disposed below the start port 28. Here, the special winning device 33 includes a special winning opening 33a opened in a belt shape, an opening / closing plate 33b for opening / closing the special winning opening 33a, and a large winning opening solenoid 33c (for operating the opening / closing plate 33b). 9), and an incoming ball detection switch 33s (see FIG. 9) for detecting an incoming game ball.

  The first decorative member 50 is provided with a plurality of LEDs. By combining these LEDs, a normal symbol display unit 51, a general symbol hold display unit 52, a first special symbol hold display unit 53, and a second special symbol are provided. A hold display unit 54 is configured. Similarly, the second decorative member 60 is provided with a plurality of LEDs, and a first special symbol display portion 61 and a second special symbol display portion 62 are configured by a combination of these LEDs.

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operation gate 27, and after the predetermined time has passed, the normal symbol hits in the normal symbol display mode or the off-normal symbol display mode. Stopped display. When the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened according to a predetermined opening pattern. A plurality of opening patterns of the second start port 28b are set. When the opening time extension function for extending the opening time of the second start port 28b is not activated, the first opening pattern (short-time opening pattern) in which the first opening time (for example, 0.1 second) is set is set and opened. When the time extension function is activated (open extension state), a second opening pattern (long-time opening pattern) in which a second opening time (for example, 4.5 seconds) longer than the first opening time is set is set. The open time extension function will be described later.

  In the present embodiment, a random number for determining whether or not a normal symbol is provided is prepared. This random number for determining whether or not a normal symbol is used determines whether or not the second starting port 28b is activated when the game ball passes through the normal symbol operating gate 27. It is used to determine whether or not the symbol is normal (whether to be in an open state). The normal symbol success / failure random number is set in advance with a hit value, and the normal symbol success / failure determination random number acquired at the timing when the game ball passes the normal symbol operation gate 27 matches the win value. Determined. When it is determined that the normal symbol is determined to be a win, the normal symbol that is stopped and displayed on the normal symbol display unit 51 is determined as the display mode of the normal symbol. On the other hand, when it is determined to be out (when the acquired normal symbol success / failure random number does not match the winning value), the normal symbol stopped and displayed in the normal symbol display unit 51 is determined as the display mode of the out of normal symbol. Is done.

  Here, normal symbol holding will be described. The normal symbol hold display section 52 displays the normal symbol hold number, and the number of game balls that have passed through the normal symbol operation gate 27 can be held up to the maximum hold number (four in this embodiment). Each time the next normal symbol win / fail determination is made and the normal symbol variation display is started, the number of unstarted times (the number of reservations) is consumed, and the number of normal symbol reservations is decreased by one. The general-purpose hold display unit 52 includes two LEDs, and can display the number of holds with an upper limit of four by combining turning off, lighting, and blinking of the two LEDs. Along with the holding of the normal symbol, a random number for determining whether or not the normal symbol is stored in a predetermined area of the RAM of the main control unit 200.

  It should be noted that the determination of whether or not the normal symbol is determined, the determination of the stop symbol of the normal symbol, the setting of the variation pattern of the normal symbol, the storage and storage of the normal symbol are performed by the main control unit 200 described later.

  Next, the special symbol will be described. In this embodiment, two special symbols, a first special symbol and a second special symbol, are provided, and accordingly, a first special symbol display unit 61 for displaying the first special symbol and a second special symbol are displayed. A second special symbol display section 62 is provided. In the following description, when “special symbol” is described, the description corresponds to both “first special symbol” and “second special symbol” unless otherwise specified.

  Each of the special symbol display units 61 and 62 includes seven LEDs, and special LEDs (first special symbol and second special symbol) are displayed by these LEDs. Each LED constituting each of the special symbol display units 61 and 62 can be turned on and off, and a plurality of display modes can be displayed for each special symbol by a combination of turning on and off of each LED. And in the 1st special symbol display part 61 and the 2nd special symbol display part 62, the specific combination is set as a big hit symbol among the combinations of the special symbols displayed by the combination of lighting and extinction of 7 LEDs respectively. In addition, combinations other than the jackpot symbol are set as outliers. In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off.

  When the game ball enters the first start port 28a, the first special symbol display unit 61 starts displaying the first special symbol in a variable manner. After the predetermined time has elapsed, the first special symbol is either a big hit symbol or a missed symbol. The symbol variation game of the first special symbol that is stopped and displayed is performed. In addition, when a game ball enters the second start port 28b, the second special symbol starts to be displayed on the second special symbol display unit 62, and after the predetermined time has passed, the second special symbol is a big hit symbol or a missed symbol. The symbol variation game of the second special symbol that is stopped and displayed is performed.

  In the present embodiment, the first special symbol random number acquired when the game ball enters the first start port 28a and the second special random number acquired when the game ball enters the second start port 28b. Design random numbers are provided. The first special symbol random number includes a first special symbol success / failure random number used for determining whether or not to execute the jackpot game, and a first special symbol random number for determining whether to stop the first special symbol. A big hit type determining random number (first special symbol determining random number) and a reach random number for determining whether or not to perform a reach effect are included. Similarly, for the second special symbol random number, a second special symbol success / failure random number used for determining whether or not to execute the jackpot game is determined, and a stop symbol of the second special symbol is determined. The second jackpot type determining random number (second special symbol determining random number) for the purpose and the reach random number for determining whether or not to perform the reach effect are included.

  As the game ball enters the first start port 28a, a first special symbol success / failure determination random number and a first jackpot type determination random number are acquired. The big hit type determination random number is stored as a hold (first special symbol hold) in a predetermined area (first hold storage area) of the RAM of the main control unit 200. As the game ball enters the second start port 28b, a second special symbol success / failure determination random number and a second jackpot type determination random number are acquired, and a predetermined area (second) in the RAM of the main control unit 200 is acquired. Is stored as a hold (second special symbol hold) in the hold storage area).

  Here, the holding of special symbols will be described. The first special symbol hold display unit 53 and the second special symbol hold display unit 54 are each composed of two LEDs, and the number of holds can be set up to 4 each by combining the turn-off, lighting, and blinking of the two LEDs. Can be displayed.

  The number of game balls that have entered the first start opening 28a can be held until the maximum number of reserved balls (four in this embodiment) is reached as the number of first special symbol held. The first special symbol hold number is acquired every time a game ball enters the first start port 28a and is stored in a predetermined area (first hold storage area) of the RAM of the main control unit 200. This corresponds to the number (stored number) of special symbol random numbers (first special symbol success / failure determination random number, first jackpot type determination random number, reach random number). In the present embodiment, as the game ball enters the first starting port 28a, the first special symbol determination random number together with the first special symbol success / failure determination random number is also acquired. This also corresponds to the number of stored random numbers for determining the first jackpot type. The first special symbol hold count is digested and decreased by one each time the first special symbol determination is made and the first special symbol variation display is started.

  The number of game balls that have entered the second start port 28b can be held until reaching the maximum number of reservations (four in this embodiment) as the second special symbol reservation number. The second special symbol hold number is acquired every time a game ball enters the second start port 28b and is stored in a predetermined area (second hold storage area) of the RAM of the main control unit 200. This corresponds to the number (stored number) of special symbol random numbers (second special symbol success / failure determination random number, second jackpot type determination random number, reach random number). In the present embodiment, as the game ball enters the second starting port 28b, the second special symbol determination random number is also acquired together with the second special symbol success / failure random number, so the second special symbol hold number is This also corresponds to the number of stored random numbers for determining the second jackpot type. The second special symbol hold count is digested each time the second special symbol success / failure determination is performed and the variation display of the second special symbol is started, and decreases by one. On-hold storage and on-hold digestion of the first and second special symbols are performed by the main control unit 200 described later.

  The gaming machine 1 according to the present embodiment is configured to perform a second special symbol priority variation process in which the variation display of the second special symbol is executed with priority over the variation display of the first special symbol. That is, when both the number of the first special symbol hold and the number of the second special symbol hold are “1 or more”, the second special symbol is preferentially displayed in a variable manner over the first special symbol. The reservation of the symbol is preferentially consumed. When the first special symbol reservation count is “1 or more” and the second special symbol reservation count is “zero”, the variable display of the first special symbol is executed.

  A special symbol winning / determining random number is set with a winning / determining hit value (big hit value), and the special symbol acquired at the timing when the game ball enters the first starting port 28a or the second starting port 28b. When the random number for determination of success / failure coincides with the jackpot value, it is determined as a big hit in the first special symbol determination of success / failure. The first special symbol success / failure determination is performed when the first special symbol starts variable display, and the second special symbol correctness determination is performed when the second special symbol starts variable display.

  When the first special symbol success / failure determination random number matches the jackpot value, it is determined that the jackpot value is determined, and the first special symbol that is stopped and displayed on the first special symbol display unit 61 is determined as the jackpot symbol. Then, if the first special symbol success / failure random number does not coincide with the jackpot value, the first special symbol that is stopped and displayed on the first special symbol display unit 61 is determined to be an out symbol. Similarly, when the second special symbol success / failure determination random number coincides with the jackpot value, the jackpot is determined, and the second special symbol stopped and displayed on the second special symbol display unit 62 is determined as the jackpot symbol. Then, if the second special symbol success / failure determination random number does not coincide with the jackpot value, it is a failure, and the second special symbol that is stopped and displayed on the second special symbol display unit 62 is determined to be a missed symbol.

  The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The special symbol variation pattern is selected by lottery using a variation pattern random number from a variation pattern table in which a plurality of variation patterns are stored when the special symbol success / failure determination is executed.

  A plurality of special symbol variation pattern tables are prepared, and each is selected and used according to the gaming state (special symbol variation mode). In addition, each variation pattern table selected according to the gaming state is selected when the result of the special symbol success / failure determination is a big hit and when the result of the special symbol success / failure determination is out of place. And a deviation variation pattern table.

  First special symbol success / failure determination, second special symbol success / failure determination, determination of variation mode (variation pattern) of first special symbol, determination of variation mode (variation pattern) of second special symbol, stop of first special symbol Determination of symbol, determination of stop symbol of second special symbol, change display and stop display of first special symbol, change display and stop display of second special symbol, priority change of second special symbol will be described later. 200.

  Next, the jackpot game will be described. When the special symbol stopped and displayed on the first special symbol display unit 61 or the second special symbol display unit 62 is the above-mentioned jackpot symbol (when the result of the special symbol success / failure determination is a big hit), the main control unit 200 Starts a big hit game (special game) that is relatively advantageous to the player. The big hit game is started by setting the big hit game flag to ON, and the big winning device 33 is operated, in other words, the big winning opening 33a is opened and closed a plurality of times, so that the game balls to the big winning opening 33a are opened. It gives a player a profit (prize ball) for entering the ball. The big hit game is realized by repeatedly executing a big hit game process by the main control unit 200 described later.

  During the big hit game, the big prize device 33 is operated, and a predetermined number of prize balls (15 in this embodiment) are paid out in accordance with the game balls entering the big prize opening 33a. In other words, the game ball that has entered the grand prize winning port 33a is detected by passing the game ball with the big winning port entrance ball detection switch 33s (not shown) disposed in the big prize winning port 33a. Will be paid out.

  Then, with the start of the big hit game, the big winning device 33 is continuously operated, and the big winning opening / closing operation for switching the big winning port 33a between the open state and the closed state is continuously performed a plurality of times. With the start of the operation of the special winning device 33, the special winning opening 33a is opened. This open state is ended when a predetermined end condition is established, and the open special winning opening 33a is closed. As a predetermined ending condition, when the opening time of the grand prize opening 33a reaches a specified time (30 seconds in this embodiment) or the number of game balls that have entered the open big opening 33a is a predetermined number (this implementation) In the example, it is possible to reach 10). In the case where one round game is performed from the start to the end of the open state of the big prize winning opening 33a, the maximum number of consecutive rounds (15 rounds in this embodiment) that can continue the big hit game is set.

  In the gaming machine of the present embodiment, after the big hit game is finished, the specific game state in which the fluctuation time shortening function, the opening time extension function, and the probability fluctuation function are activated (the “non-probable state with electric support” or “the positive change with electric support” described later). Status "etc.) is started. The variable time shortening function, the opening time extending function, and the probability varying function operate by setting the fluctuation shortening flag, the opening extension flag, and the probability changing flag to ON, respectively. The variable time shortening function and the open time extending function start simultaneously and end simultaneously. In the following description, when only one of the functions related to the operating state of the variable time shortening function and the open time extending function is described, the other function is also paired. For example, when it is described in the following description that “the variable time shortening function is operating”, this description can be interpreted as “the opening time extending function is also operating”. When it is described that “the function is operating”, this description can be understood as “the variable time reduction function is operating”.

  In the gaming machine 1 of the present embodiment, when the result of the special symbol success / failure determination is a normal big hit (the special symbol stop symbol is a normal big hit symbol), after the big hit game ends, the probability variation function is not activated. By operating the time shortening function and the open time extending function, the “non-probable change state with electric support” is started. The uncertain change state with electric support is realized by the control of the main control unit 200. By the activation of the opening time extension function, the opening time of the second start port 28b is extended from the first opening time (for example, 0.2 seconds), which is the normal setting time, to the second opening time (for example, 5 seconds). . As a result, the frequency of entering the game ball into the second start port 28b is higher than that at normal time (when the opening time extension function is not activated). The non-probable change state with electric support is configured to continue until the number of changes of the special symbol reaches a predetermined number (100 in this example) after the big hit game ends.

  Also, if the result of the special symbol success / failure determination is a probable big hit (the stop symbol of the special symbol is a probable big hit symbol), after the big hit game ends, the probability variation function, variation time shortening function and open time extension function are activated. , “Electric support and probable change state” is started. A jackpot game started by a probable jackpot game is also referred to as a “probable jackpot game”. The probability variation state with the electric support is realized by the control of the main control unit 200. In this state, the probability that the result of the special symbol success / failure determination result is a big hit, that is, a special bonus, together with the variable time shortening function and the open time extending function. A probability variation function is activated that changes (improves) the probability that the symbol is a big hit symbol. The probability variation state with the electric support is configured to continue until the next jackpot game is started after the jackpot game ends.

  While the probability variation function is in operation, the probability of winning the special symbol success / failure determination increases as the bonus winning value for special symbol success / failure determination increases. Specifically, a low probability lottery table and a high probability lottery table in which the number of jackpot winning values is set larger than that of the low probability lottery table are prepared as the lottery tables in which the big hit winning value is set. When the probability variation function is not activated, the special symbol success / failure determination is performed using the low probability lottery table, so that the probability that the random number for special symbol success / failure coincides with the jackpot winning value is low (in this embodiment, 1 / 200), and when the probability variation function is activated, a special symbol success / failure determination is performed using the high probability lottery table, whereby the probability that the special symbol success / failure determination random number matches the jackpot winning value is high (1 in this embodiment). / 20).

It has been. In a state in which the first shielding member 26 and the second shielding member 27 cover the front surface of the display area V of the effect display device 25, the first detected portion 26a and the first detected portion 26a and the shielding member 26, 27 are viewed from the direction perpendicular to the plate surface. The second detected parts 27a overlap.

  Further, a shielding member detection sensor 25s for detecting whether or not the first shielding member 26 and the second shielding member 27 cover the front surface of the effect display device 25 is provided. The shielding member detection sensor 25s is disposed below the effect display device 25, and more specifically, in a state where the first shielding member 26 and the second shielding member 27 cover the front surface of the effect display device 25, The first detected part 26a and the second detected part 27a are arranged at overlapping positions.

  The shielding member detection sensor 25s is configured as an optical sensor (photosensor) having a known configuration including a light emitting element (for example, a light emitting diode) and a light receiving element (for example, a phototransistor). The shielding member detection sensor 25s has a structure in which the light emitting element and the light receiving element face each other, and in a state where the first shielding member 26 and the second shielding member 27 cover the front surface of the effect display device 25, The detection part 26a and the second detected part 27a are located between the light emitting element and the light receiving element. The light emitting element always emits light toward the light receiving element, and when the detected portions 26a and 27a do not exist between the light emitting element and the light receiving element, the light receiving element receives light emitted from the light emitting element. It has become. When the detected portions 26a and 27a exist between the two elements, the light reaching the light receiving element among the light generated by the light emitting element is limited, and the output of the light receiving element is changed. The presence of the detected parts 26a and 27a can be determined by detecting the output. Note that the output signal of the shielding member detection sensor 25s is configured to be input to the sub-control unit 260.

  As shown in FIG. 3, when the first shielding member 26 and the second shielding member 27 cover the front surface of the display area V of the effect display device 25, between the light emitting element and the light receiving element of the shielding member detection sensor 25 s. In other words, the first state is such that two detected parts 26a and 27a overlap each other. In the first state, the two detected portions 26a and 27a are positioned in series on the line connecting the light emitting element and the light receiving element of the shielding member detection sensor 25s.

The transmittance and the light transmittance of the two detected portions 26a and 27a can be made different. Specifically, one detected portion 26a, 27a can pass part of the light from the light emitting element, and two detected portions 26a, 27a pass the light from the light emitting element. Cut off. As a result, the intensity of light received by the light receiving element in the three states consisting of the first state (FIG. 3), the second state (FIGS. 4 and 5), and the third state (FIG. 6) is reduced. Each will be different. Specifically, in the first state (FIG. 3), light from the light emitting element hardly reaches the light receiving element, and in the second state (FIGS. 4 and 5), a part of the light from the light emitting element. Reaches the light receiving element, and in the third state (FIG. 6), the light from the light emitting element directly reaches the light receiving element. For this reason, the intensity of light received by the light receiving element increases in the order of first state <second state <third state. In the shielding member detection sensor 25s, the voltage level of the output signal changes according to the intensity of light received by the light receiving element.

  FIG. 7 shows the voltage level of the output signal of the shielding member detection sensor 25s corresponding to each state. As shown in FIG. 7, the voltage of the output signal of the shielding member detection sensor 25s is 4 to 5 volts in the third state where the detected portions 26a, 27a are not detected, and the two detected portions 26a, In the second state in which only one of 27a is detected, the voltage is 2 to 4 volts, and in the first state in which two detected parts 26a and 27a are detected, the voltage is less than 2 volts.

  FIG. 8 shows the configuration of the sub-control unit 260 that controls the shielding member motors 26m and 27m. As shown in FIG. 8, the sub-control unit 260 controls the output voltage detection means for detecting the voltage of the output signal of the shielding member detection sensor 25s, and the operation for controlling the first shielding member motor 26m and the second shielding member motor 27m. Control means are provided.

That is, the output voltage detection means detects the two detected portions 26a and 27a based on the voltage of the output signal of the shielding member detection sensor 25s in the first state (FIG. 3) and the two detected values. Three states are discriminated: a second state (FIGS. 4 and 5) in which only one of the parts 26a and 27a is detected, and a third state (FIG. 6) in which the detected parts 26a and 27a are not detected. be able to. The output voltage detection means is a signal indicating that the operation state is the first state when it is in the first state with respect to the operation control means for controlling the first shielding member motor 26m and the second shielding member motor 27m. (First signal) is transmitted, a signal indicating the second state (second signal) is transmitted in the second state, and a third state is transmitted in the third state. A signal (third signal) indicating this is transmitted.

  In the present embodiment, the first shielding member motor 26m and the second shielding member motor 27m (also simply referred to as a motor) are constituted by stepping motors. Therefore, the operation control means rotates the motor (26m, 27m) by a predetermined number of pulses as control for moving the first shielding member or the second shielding member from the first position to the second position. Execute. And when the 1st shielding member or the 2nd shielding member moves to the position as planned by the said control, the signal of any one of the 1st signal, the 2nd signal, or the 3rd signal will be received.

  Accordingly, based on the output voltage of the shielding member detection sensor 25s, the first shielding member 26 or the second shielding member 27 covers the entire display area V of the effect display device 25, or the first shielding member 26 or A state in which the right half or the left half of the display area V of the effect display device 25 is covered with one of the second shielding members 27, and the display area V of the effect display device 25 is covered by the first shielding member 26 and the second shielding member 27. An uncovered state can be determined. When the first shielding member or the second shielding member is caught by another member or dust and stopped in the middle of the movement, even if the predetermined movement control is executed, the first signal, the second signal, or Any one of the third signals cannot be received. In this case, the correction is performed by continuing the motor control until the first signal, the second signal or the third signal is received, or performing a retry operation for executing the motor control for a predetermined time (predetermined pulse). Plan.

  Here, the symbol variation effect realized under the control of the sub-control unit 260 and the effect display control unit 280 described later will be described. As shown in FIGS. 3A to 6A, the display area V of the effect display device 25 is provided with an effect symbol display unit 25 a for displaying effect symbols. This effect symbol is displayed in conjunction with the change display and stop display of the first special symbol on the first special symbol display unit 61 or the second special symbol on the second special symbol display unit 62. Further, in the display area V of the effect display device 25, the part excluding the effect symbol display unit 25a is a background display region in which various background symbols including characters, figures, symbols, characters, and the like are displayed. As described above, since the effect display device 25 is arranged in the center of the game board 20 (game area 21), the player usually displays the content displayed in the display area V of the effect display device 25 (particularly the effect symbol). It will play a game paying attention to.

  In the present embodiment, a three-digit number symbol consisting of “1” to “9” is used as the effect symbol, and the effect symbol display unit 25a displays the right symbol display unit on which the left symbol is displayed and the middle symbol. The middle symbol display area and the left symbol display area on which the right symbol is displayed are composed of three symbol display areas. The effect symbol display unit 25a has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of each symbol display unit, in this case, in the vertical direction (vertical direction).

  The effect symbol starts when the first special symbol or the second special symbol starts the variable display, and when the first special symbol or the second special symbol is stopped and displayed at any of the symbols, the effect symbol Is stopped and displayed with a symbol corresponding to the stop symbol of the first special symbol or the second special symbol. In the effect symbol, a symbol combination having the same three digits corresponds to the special symbol jackpot symbol, and the other symbol combinations correspond to the special symbol missing symbol.

  The determination of the variation pattern (variation pattern) and stop symbol of the effect symbol is configured to be performed by the sub-control unit 260 based on the variation pattern designation command and the special symbol information designation command transmitted from the main control unit 200. . Here, the variation pattern designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates the variation pattern of the special symbol. Specifically, the variation time of the special symbol and the presence / absence of the reach effect The contents of the production are shown. The main control unit 200 determines a variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol. Based on the special symbol variation pattern determined by the main control unit 200, the sub-control unit 260 determines the effect pattern of the effect symbol displayed on the effect symbol display unit 25a. The special symbol information designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates a special symbol stop symbol, and the main control unit 200 determines the special symbol according to the determination result of the special symbol. The stop symbol of is decided at random (by random number lottery). Then, based on the special symbol information designation command indicating the special symbol stop symbol determined by the main control unit 200, the sub control unit 260 determines the stop symbol of the effect symbol to be stopped and displayed on the effect symbol display unit 25a.

  In the display area V of the effect display device 25, a hold display effect for displaying the number of special symbols held, a big hit game start effect (fanfare effect) executed at the start of the big hit game, and a round effect (big hit) executed during the big hit game (Game effect), jackpot game end effect (ending effect) executed at the end of the jackpot game, probability change notification effect for notifying the operating state of the probability variation function, and the like are performed. In this embodiment, the probability variation notification effect is executed in the next continuation state, and the probability variation notification effect is not executed in the number cut state. Thereby, in the count-off state, it is possible to enter a probability variation non-notification state (latent probability variation state in the case of probability variation) in which the operation state of the probability variation function becomes unknown after the open extension state ends. This makes it difficult for the player to end the game even if the open extended state ends (since it is disadvantageous to leave the probability variation state), it is possible to improve the operating rate of the gaming machine. These various effects are executed by the sub control unit 260 based on commands transmitted from the main control unit 200 as the game progresses.

If the stop symbol of the special symbol is a jackpot symbol, the open time extension function, the variation time shortening function, and the probability variation function during operation are terminated, and the jackpot game is started.

  In the big hit game process (S600), the special winning opening 33a is opened, and when a predetermined time has elapsed or a specified number of game balls have entered the special winning opening 33a, the special winning opening 33a is closed. Then, the round game from when the special winning opening 33a is opened until it is closed is executed until the maximum number of consecutive rounds is reached. At the end of the big hit game, a process of starting the opening time extension function, the fluctuation time reduction function, and the probability fluctuation function is performed.

  In the present embodiment described above, the first detected portion 26a of the first shielding member 26 and the second detected portion 27a of the second shielding member 27 are made of a translucent member having a predetermined light transmittance. The light transmittance of one detected portion 26a, 27a is different from the light transmittance of two detected portions 26a, 27a. Thereby, the shielding member detection sensor 25s has a first state (FIG. 3) in which two detected portions 26a and 27a exist between the light emitting element and the light receiving element, and the light emitting element and the light receiving element. In the second state (FIGS. 4 and 5) in which one detected portion 26a, 27a exists between the second detection state and the detected portion 26a, 27a does not exist between the light emitting element and the light receiving element. The output signal can be made different in the state 3 (FIG. 6). As a result, the state of the two shielding members 26 and 27 can be detected by one shielding member detection sensor 25s.

  Here, the correspondence between the present embodiment and the components of the present invention will be described. The “first shielding member” corresponds to the “first movable member” of the present invention, and the “second shielding member” is the book. It corresponds to the “second movable member” of the invention, the “shielding member detection sensor” corresponds to the “detection means” of the present invention, and the sub-control unit 260 corresponds to the “operation control means” of the present invention.

(Other embodiments)
As mentioned above, although the Example of this invention was described, this invention is not limited to this, Unless it deviates from the range described in each claim, it is not limited to the description word of each claim, and those skilled in the art Improvements based on the knowledge that a person skilled in the art normally has can be added as appropriate to the extent that they can be easily replaced.

  For example, in the said Example, it comprised so that the to-be-detected parts 26a and 27a provided in the shielding members 26 and 27 which cover the display area V of the effect display apparatus 25 may be detected by the shielding member detection sensor 25s. However, the present invention is not limited to this, and it can be configured to detect the detected parts of different types of movable members.

  Moreover, in the said Example, although it comprised so that the two to-be-detected parts 26a and 27a could be detected with the shielding member detection sensor 25s, it may comprise not only this but three or more to-be-detected parts. Good. In this case, for example, in a configuration in which three detected parts are detected, there are three detected parts between the light emitting element and the light receiving element, and there are two detected parts between the light emitting element and the light receiving element. The voltage level of the output signal of the detection sensor is in four states including a state where one detected portion exists between the light emitting element and the light receiving element and a state where no detected portion exists between the light emitting element and the light receiving element. It will be different.

  Further, in each of the above embodiments, the game balls supplied from the island facilities of the game hall are used as “rental balls” or “prize balls”, and various winning ports (first start port, second game port) provided on the game board are used. A game machine (pachinko machine) that gives a player a game profit (game value) by paying out a predetermined number of prize balls according to the number of game balls that enter the starting gate, big prize opening, etc. Although an example in which the present invention is applied has been described, the present invention can also be applied to a type of gaming machine that provides gaming profits in a form different from “payout of prize balls”.

  For example, when a game ball is entered into various winning holes, data indicating the amount of profit (the magnitude of the game value) corresponding to the ball is stored in the RAM of the main control unit or the payout control unit. Thus, the present invention can also be applied to a type of gaming machine in which a gaming profit (game value) is given to a player. In this case as well, the same effect as in the above embodiment can be obtained. As a type of gaming machine in which gaming profit (game value) is converted into data and given to the player, a gaming machine that circulates and uses a plurality of gaming balls built in the gaming machine, specifically, Examples of the game machine (so-called enclosed game machine) configured to return the game ball discharged to the back surface of the game board through various winning holes or out holes to the launch position and launch it again.
