The connecting arm 74 of the present embodiment is formed in a substantially linear shape and is slidable in the moving direction of the shielding plate 71 (vertical direction in FIG. 8). Further, a connecting arm 74 provided at the lowermost end in FIG. 8 is fixed to the belt 83.

  In the shutter device 70 of the first embodiment, an annular belt 83 is provided over the movement range of the shielding plate 71 on both outer sides of the shielding plate 71 as moving means for moving the shielding plate 71. The belt 83 is provided on the connecting arm 74 along the moving direction. A first pulley 84 on the idle side is provided at the upper end of the belt 83, and a second pulley 85 on the drive side is provided at the lower end of the belt 83, and the belt 83 is between the first pulley 84 and the second pulley 85. It is arranged to tie. The two second pulleys 85 are connected by a connecting shaft 86 and are configured to rotate synchronously. The second pulley 85 is connected to the motor 88 via a gear 87. As the motor 88, for example, a stepping motor can be used. In the present embodiment, two belts 83 are rotated by one motor 88. The motor 88 is controlled by a sub-control unit 260 described later.

  A first sensor 78 is provided near the upper end of the belt 83, and a second sensor 79 is provided near the lower end of the belt 83. The first sensor 78 is provided at an upper limit position in a range in which the upper connecting arm 74 moves by the belt 83, and detects that the upper connecting arm 74 has reached the upper limit of the movable range. The second sensor 79 is provided at a lower limit position in a range in which the lower end connecting arm 74 is moved by the belt 83, and detects that the lower end connecting arm 74 has reached the lower limit of the movable range. As these sensors 78 and 79, for example, optical sensors can be used. Further, the shutter device 70 is provided with a solenoid 80 for opening and closing the shielding plate 71.

  As shown in FIG. 9A, FIG. 11A, and FIG. 13A, ribs 71c are provided on the short sides located at the left and right ends of the shielding plate 71. When the shielding plate 71 shown in FIG. 9A is in a vertical state, the rib 71c protrudes from the plate surface of the shielding plate 71 to the front side, and the lower end of the shielding plate 71 shown in FIG. In the state of being moved and inclined, the rib 71 c protrudes upward and faces the lower surface of the upper shielding plate 71.

  Moreover, as shown in FIG.9 (b), the long side of the shielding board 71 is comprised so that it may incline with respect to a plate surface. Specifically, in the case where the shielding plate 71 shown in FIG. 9B is in a vertical state, the long sides positioned at the upper and lower ends of the shielding plate 71 are on the front side (player side) and the back side (design) The display device 25 (display screen side) constitutes an inclined surface on the upper side. The upper and lower inclined surfaces of the shielding plates 71 adjacent in the vertical direction face each other, and when viewed from the front side, the upper and lower inclined surfaces overlap each other. For this reason, when the shielding plate 71 is in the vertical state, the inclined surfaces of the adjacent shielding plates 71 interfere with each other, and the shielding plate 71 moves in the direction in which the upper end moves forward and the lower end moves rearward (FIG. 9 ( b) cannot rotate in the counterclockwise direction), but can rotate only in the direction in which the upper end moves backward and the lower end moves forward (clockwise in FIG. 9B).

  FIG. 14 is a front view showing a frame portion of the shutter device 70, and shows a state in which the shielding plate 71, the solenoid 80, the belt 83, and the like are removed. As shown in FIG. 14, a guide groove 70 a for guiding the connecting arm 74 is formed in the frame portion of the shutter device 70. The guide groove 70a is provided corresponding to each connecting arm 74, and has a width that allows the connecting arm 74 to be fitted. Each guide groove 70 a guides the corresponding connecting arm 74 and restricts the movement range of the connecting arm 74.

  The guide groove 70a is moved from a state where the plurality of shielding plates 71 are moved above the display area of the symbol display device 25 (fully open state) to a state where the front side of the symbol display device 25 is shielded (fully closed state). It is formed so that it can be. The upper end position of each guide groove 70a corresponds to the fully open state (see FIG. 10) in which the shielding plate 71 is moved above the display area of the symbol display device 25, and the lower end position of each guide groove 70a is the symbol of the shielding plate 71. This corresponds to a fully closed state (see FIG. 8) in which the front side of the display device 25 is shielded.

  15 and 16 are enlarged perspective views of the connecting arm 74, solenoid 80, etc. in FIG. FIG. 15 shows a state where the shielding plate 71 shields the front side of the symbol display device 25 (fully closed state), and FIG. 16 shows a state where the shielding plate 71 is moving upward.

  As shown in FIG. 15, the connecting arm 74 has a straight portion 74a and a cylindrical portion 74b. Engagement portions 74c and 74d are formed in the linear portion 74a. The adjacent connecting arms 74 can be engaged with each other by the engaging portions 74c and 74d, and thereby the movement of the connecting arms 74 in the downward direction in FIG. 8 is restricted. A through-hole through which the rotation shaft 71a of the shielding plate 71 passes is formed in the cylindrical portion 74b. A receiving portion 74e is formed on the upper portion of the cylindrical portion 74b. The receiving portion 74e contacts the cylindrical portion 74b of the connecting arm 74 directly above when the connecting arm 74 moves.

  Next, the movement of the shielding plate 71 of the shutter device 70 will be described. By driving the motor 88, the belt 83 rotates, and the lowermost connecting arm 74 fixed to the belt 83 moves upward along the guide groove 70a. At this time, since the long side of the shielding plate 71 is inclined so that the back side becomes higher (see FIG. 9B), when the shielding plate 71 moves upward, the upper end of the shielding plate 71 is on the upper side. While entering the back side (back side) of the shielding plate 71, the lower end of the shielding plate 71 on the upper side moves forward, and the shielding plates 71 are likely to overlap. As the shielding plate 71 rises, the receiving portion 74e of the connecting arm 74 moved upward comes into contact with the lower portion of the cylindrical portion 74b of the connecting arm 74 directly above (see FIG. 16).

  In addition, each connecting arm 74 pushes up the connecting arm 74 directly above, and the lower shielding plate 71 pushes up the upper shielding plate 71, and all the shielding plates 71 connected to the connecting arm 74 are overlapped with each other. It moves to the upper end position of 70a. When the lower shielding plate 71 pushes up the upper shielding plate 71, the ribs 71c of the lower shielding plate 71 are in contact with the back side of the upper shielding plate 71. The contact area is reduced, and the shielding plates 71 can be smoothly overlapped. As a result, the shielding plate 71 is smoothly raised. In this way, when all the shielding plates 71 move above the display area of the symbol display device 25, the shield plate 71 does not exist on the front surface side of the display area of the symbol display device 25 (see FIG. 3). b), FIG. 10, FIG. 11). When all the shielding plates 71 are moved upward from the display area of the symbol display device 25 and are fully opened, the detection piece 74s provided on the connecting arm 74 of the uppermost shielding plate 71 is the first sensor. 78, and the first sensor 78 detects that all the shielding plates 71 are in the upper limit position (that is, in a fully open state) (see FIG. 10).

  Next, by reversely rotating the motor 88, the belt 83 rotates reversely, and the lowermost connecting arm 74 fixed to the belt 83 moves downward along the guide groove 70a. The other connecting arms 74 move downward due to their own weights of the shielding plates 71 and stop at the lower end position of the guide groove 70a. Even when each shielding plate 71 is deployed (lowered), the ribs 71c of the lower shielding plate 71 are in contact with the back side of the upper shielding plate 71, so that they are in contact as compared with the case where they are in contact with the entire plate surface. The area is reduced, and each shielding plate 71 can be smoothly deployed. As a result, the shielding plate 71 is lowered smoothly. Since the rotating shaft 71a of each shielding plate 71 is shifted upward from the center position on the side of the shielding plate 71, each shielding plate 71 is in a vertical state due to its own weight, while being on the front side of the symbol display device 25. Unfold one by one. Since the inclined surfaces of the shielding plates 71 adjacent to each other interfere with each other and the shielding plates 71 stop in a vertical state, the shielding plates 71 can easily form the same surface. Thus, when all the shielding plates 71 are moved to the front side of the symbol display device 25, the display area of the symbol display device 25 is fully closed with the shielding plate 71 (FIG. 3A). (Refer FIG. 8, FIG. 9).

  As described above, since all the shielding plates 71 that have moved upward from the screen of the symbol display device 25 are overlapped with each other, the overlapping shielding plates 71 surround, for example, the periphery of the screen of the symbol display device 25. If it is stored in the upper back side (inside the center accessory) of the center accessory (not shown), it is possible to prevent the player from noticing the presence of all the shielding plates 71 moved upward. Then, as the game progresses, the shielding plate 71 is lowered in accordance with the effect image displayed on the screen of the symbol display device 25, so that the entire screen of the symbol display device 25 is suddenly obscured. It becomes possible.

  Next, an opening / closing mechanism that individually opens and closes the plurality of shielding plates 71 of the shutter device 70 will be described. In the solenoid 80 of this embodiment, a movable iron core (not shown) is provided on the back side of the paper surface, and this movable iron core (not shown) is perpendicular to the paper surface, that is, in a direction orthogonal to the plate surface of the shielding plate 71. Move in a certain direction.

  As shown in FIG. 8, a rotation shaft 71 a serving as a rotation center of the shielding plate 71 is provided on one side (one short side) of each of the six shielding plates 71. The rotating shaft 71a is provided slightly shifted upward from the center position on the side (short side) of the shielding plate 71. When no external force is applied to the shielding plate 71, the shielding plate 71 is in a vertical state. Further, as shown in FIG. 15, the rotary shaft 71a is provided with an action shaft 71b for operating the shielding plate 71 by receiving an external force. The action shaft 71b is provided on one end side (right end when viewed from the front side) of the rotation shaft 71a. Since the action shaft 71b is provided so as to be offset from the center of the rotation shaft 71a, the rotation shaft 71a rotates when an external force acts on the action shaft 71b.

  As shown in FIG. 15, a bracket 89 is connected to the movable iron core (not shown) of the solenoid 80. The bracket 89 has a U-shaped cross section, groove-shaped recesses are formed along the moving direction (vertical direction) of the shielding plate 71, and both ends of the shielding plate 71 in the moving direction and the rotation shaft 71 a of the shielding plate 71. Opposite sides are open.

  In a state where the shielding plate 71 covers the display area of the symbol display device 25, the action shaft 71 b of the shielding plate 71 is located in the recess of the bracket 89. Since the concave portion of the bracket 89 is open at both ends in the moving direction of the shielding plate 71, the operating shaft 71 b of the shielding plate 71 passes through the concave portion of the bracket 89 when the belt 83 rotates and the shielding plate 71 moves. can do.

  By turning the solenoid 80 on and off, the bracket 89 moves in the front-rear direction (perpendicular to the paper surface) of the gaming machine 1. When the solenoid 80 is not energized, the shielding plate 71 is in a vertical state and is in a closed state that shields the display area of the symbol display device 25 (see FIGS. 3A, 8 and 9). ). Then, the solenoid 80 is turned on by energization, and the movable iron core (not shown) is moved to the front side of the shielding plate 71 (player side, that is, the front side of the paper in FIG. 8) (becomes an adsorption state). ), The bracket 89 presses the action shaft 71 b of the shielding plate 71 toward the front side of the shielding plate 71. As a result, the shielding plate 71 rotates about the rotation shaft 71a to change from the vertical state to the horizontal state, and the individual shielding plates 71 are opened (see FIGS. 3C, 12 and 13).

  Further, as shown in FIG. 8, in this embodiment, solenoids 80 are provided corresponding to a plurality of (six in this example) shielding plates 71, and each solenoid 80 shields each shielding plate 71 with another shielding. The plate 71 is configured to open and close independently. Thereby, a part of the shielding plates 71 among the plurality of shielding plates 71 can be opened and closed independently of the other shielding plates 71, and an effect display performed on the screen by the symbol display device 25 is displayed to the player. In this way, it is possible to produce novel effects such as partially visible.

  According to the configuration of the opening / closing mechanism described above, the movable iron core (not shown) of the solenoid 80 moves in the front and back direction of the shutter device 70. Therefore, the arrangement space of the solenoid 80 in the moving direction of the shielding plate 71 (vertical direction in FIG. 8). Can be reduced. Further, since the solenoid 80 directly presses the shielding plate 71, the opening / closing mechanism of the shielding plate 71 can be simplified, the movement when the shielding plate 71 opens and closes can be made smooth, and the shielding plate 71 opens and closes. The operation sound at the time can be reduced.

  Next, the decorative design displayed on the shielding plate 71 of the shutter device 70 will be described. FIG. 17 is a front view of the symbol display device 25 and the shutter device 70 when the display surface of the symbol display device 25 is in an invisible state.

  As the shielding plate 71, a colored transparent plate (translucent plate) having translucency is used. The colored transparent plate can be formed by coloring a transparent plate such as a polycarbonate plate or an acrylic plate with an achromatic color having a low lightness such as dark gray or black, or a chromatic color having a low lightness / saturation. In the present embodiment, a transparent plate colored in black and having a low transparency (for example, a so-called smoke film or privacy glass, which is used for automobile window glass to prevent ultraviolet rays and prevent temperature rise in the vehicle) ) Is a shielding plate 71.

  On the back surface of the shielding plate 71 (the surface on the back side of the game board 20), a decorative symbol 90 is displayed. The decorative symbol 90 is configured as an arbitrary symbol having a predetermined color. The decorative pattern 90 of this embodiment has a lightning pattern made of translucent blue. The decorative design 90 has translucency, and can be configured, for example, by sticking a seal printed with a translucent blue lightning pattern on the back surface of the shielding plate 71. Since the decorative symbol 90 is provided on the back surface of the black transparent shielding plate 71, it is usually difficult to recognize the decorative symbol 90 from the front side of the shielding plate 71. In this embodiment, the light transmittance of the decorative design 90 is higher than the light transmittance of the shielding plate 71. The decorative design 90 corresponds to the translucent design of the present invention.

  Next, display of the decorative symbol 90 will be described. In the present embodiment, a first state where the player cannot visually recognize the decorative symbol 90 and a second state where the player can visually recognize the decorative symbol 90 can be switched. Note that the effect display using the decorative symbol 90 is performed when the symbol display device 25 does not perform a variable display such as a symbol for the effect (pseudo special symbol) or during the variable display of the symbol for the effect (pseudo special symbol). Done. Specifically, for example, during the display of a demonstration screen when the player is not playing a game, the player is notified of the possibility of occurrence of a reach or a big hit while the effect design (pseudo special design) is being changed. During the display of the notice effect to be performed, the period between the start of the reach effect and the end of the reach effect can be exemplified as between rounds in a big hit.

  First, in order to shield the display area of the symbol display device 25 with the shutter device 70, when the plurality of shielding plates 71 are moved downward from above, the display area of the symbol display device 25 is moved from above in conjunction with the movement. The first display color is sequentially set downward. In the state where the entire display area of the symbol display device 25 is shielded by the plurality of shielding plates 71 (fully closed state), the entire display area of the symbol display device 25 is set as the first display color. This first display color is a display color that cannot pass through the decorative pattern 90 of the shielding plate 71, and is a low-brightness achromatic color such as dark gray or black, or a black color with low brightness and saturation such as dark blue. A chromatic color close to can be exemplified. In this embodiment, the first display color is plain black.

  When the entire display area of the symbol display device 25 is displayed in black, which is the first display color, no light is emitted from the light source of the symbol display device 25 (non-light emitting state). The light is not irradiated from the display area of the device 25 to the back surface of the shielding plate 71. That is, the first display color, black, has zero brightness, and the light amount of the light source of the symbol display device 25 is also zero. For this reason, between the symbol display device 25 and the shielding plate 71 is in a low brightness state (dark state). In this state, no light is irradiated toward the back surface of the shielding plate 71, so that light passes through the decorative symbol 90. Never do. Therefore, the color (blue) of the decorative pattern 90 does not change, and when the player views the shielding plate 71 from the front side in such a situation, the player can recognize that the shielding plate 71 is black. However, it cannot be recognized that the decorative pattern 90 is drawn on the back side of the shielding plate 71, that is, on the back side of the shielding plate 71. As a result, the decorative pattern 90 is invisible to the player, and only the color (black) of the shielding plate 71 is visible. As described above, when the plurality of shielding plates 71 are moved from the upper side to the lower side, in conjunction with the movement, the display area of the symbol display device 25 is sequentially changed from the upper side to the lower side to be the first display color. The player can recognize that the display area of the symbol display device 25 is sequentially shielded by the shielding plate 71 from above to below.

  Next, in a state where the entire display area of the symbol display device 25 is shielded by the plurality of shielding plates 71 (fully closed state), the entire display area of the symbol display device 25 is changed to a second display color different from the first display color. To do. The second display color is a display color that can be transmitted through the decorative design 90 of the shielding plate 71 when displayed in the display area of the design display device 25. Specifically, the second display color can be an achromatic color having a higher brightness than the first display color, or a chromatic color having a brightness and saturation higher than those of the first display color. The display color of 2 is a solid white color (achromatic color having a higher brightness than the first display color).

  When the entire display area of the symbol display device 25 is set to the second display color, the light emitted from the light source of the symbol display device 25 in order to display the second display color causes the display area of the symbol display device 25 to be displayed. Thus, the shielding plate 71 is irradiated and the decorative design 90 can be transmitted. For this reason, the decorative design 90 of the lightning pattern appears as a pale color on the shielding plate 71, and the decorative design 90 is in a second state where the decorative design 90 is visible (see FIG. 17). That is, the white color that is the second display color has higher brightness than the black color that is the first display color, and the light amount of the light source of the symbol display device 25 that emits light for generating the white display color is black. More than the case where the display color is generated. For this reason, between the symbol display device 25 and the shielding plate 71 is in a high brightness state (bright state). In this state, white light irradiated toward the back surface of the shielding plate 71 is reflected on the back surface of the shielding plate 71. It reaches and passes through the decorative symbol 90. At this time, white light is transmitted through the blue decorative design 90 so that white and blue are mixed, and the decorative design 90 changes to a pale color on the back surface of the shielding plate 71. Further, the black portion of the shielding plate 71 on which the decorative pattern 90 is not provided has little light absorption because of its low light transmittance, and hardly changes in color. In such a situation, when the player views the shielding plate 71 from the front side, the player draws a decorative pattern 90 of pale color on the back of the shielding plate 71 in addition to the shielding plate 71 being black. You will be able to recognize that. As a result, to the player, the decorative symbol 90 that was not visible on the front side of the shielding plate 71 becomes visible in a pale color, and the decorative symbol 90 appears to appear on the front side of the shielding plate 71.

  Further, the mode control switch 268 and the effect switch 5d are connected to the sub-control unit 260. The mode changeover switch 268 is configured as a DIP switch and is operated by a game hall employee when the power is turned on. The mode changeover switch 268 can change the background and the appearing character in the symbol display device 25. The effect switch 5d allows the player to change the background and the appearing character in the symbol display device 25 by operating during the game.

  Next, the effect display control unit 280 will be described with reference to FIG. FIG. 22 is a block diagram showing various gaming devices connected to the effect display control unit 280. The effect display control board 280a provided in the effect display control unit 280 is provided with arithmetic circuit components (not shown) having a CPU, a RAM, a ROM, an input / output port, a VDP (video display processor), and the like. The port is connected to the sub-control unit 260.

  As shown in FIG. 22, the effect display control unit 280 is connected to a symbol display device driving board 280 a that operates the symbol display device 25. The effect display control unit 280 performs display control of the symbol display device 25 using the RAM as a work area according to a control program stored in the ROM. Display control of the symbol display device 25 by the effect display control unit 280 is performed based on a command from the sub-control unit 260. In addition, the ROM of the effect display control board 280a stores symbol image data for effects displayed on the symbol display device 25.

  Next, a shutter effect process using the shutter device 70 of the gaming machine 1 of the present embodiment will be described. In the following description, as the shutter effect process, a notice effect from the start of the variable display of the effect symbol (pseudo special symbol) in the symbol display device 25 to the occurrence of reach will be described as an example. 23 and 24 show an example of the shutter control process executed by the CPU of the sub-control unit 260 based on the program stored in the ROM of the sub-control unit 260. FIG. FIG. 25 shows the operation of the symbol display device 25 and the shutter device 70 when the shutter effect process is being performed. The sub-control unit 260 corresponds to first to fifth effect means of the present invention.

  As shown in FIG. 23, first, it is determined whether or not an effect pattern designation command has been received from the main control unit 200 (S100). The effect pattern designation command is a command for designating a special symbol variation pattern set by the main control unit 200, and includes information on the variation time of the special symbol and the presence or absence of reach production. The effect pattern designation command is output from the main control unit 200 to the sub-control unit 260 at the start of variable display of this symbol. The sub-control unit 260 can determine whether to perform an effect using the shutter device 70 from the effect pattern designation command.

  As a result of the determination process in S100, when it is determined that the effect pattern designation command has not been received (S100: NO), the shutter control process is terminated as it is. On the other hand, if it is determined that an effect pattern designation command has been received (S100: YES), it is determined whether or not a shutter origin error has occurred (S101). The shutter origin error is an error that occurs when the shielding plate 71 is not moved to the upper limit position and is not fully opened (see FIG. 3B and FIG. 10). Whether or not a shutter origin error has occurred can be determined by a shutter origin error flag set in S106 described later.

  As a result, if it is determined that the shutter origin error has not occurred (S101: NO), whether or not the rotation axis of the motor 88 is at the origin position, in other words, all the shielding plates 71 are at the upper limit position. It is determined whether or not the first sensor 78 has detected that it is fully open (S102).

  If it is determined that a shutter origin error has occurred (S101: YES), it is determined whether or not to perform a shutter effect using the shutter device 70 (S103). As a result, when it is determined that the shutter effect is not performed (S103: NO), the shutter control process is ended as it is. On the other hand, when it is determined that the shutter effect is to be performed (S103: YES), whether or not the motor 88 is at the origin position, in other words, all the shielding plates 71 are at the upper limit position (the state is fully open). ) Is determined by the first sensor 78 (S102).

  As a result of the determination process of S102, it is determined that the first sensor 78 has not detected that the motor 88 is not in the origin position, that is, that all the shielding plates 71 are in the upper limit position (that is, in the fully open state). In this case (S102: NO), the motor 88 is returned to the origin position, and the origin return process is performed in which all the shielding plates 71 are moved upward to make them fully open (S104). Here, although it is determined in the processing of S101 that the shutter origin error has not occurred (S101: NO), the reason for determining that the motor 88 is not at the origin position (S102: NO) is as follows. It is mentioned. In other words, when the special symbol changes last time, an effect is performed using the shutter device 70 that fully closes the display area of the symbol display device 25, and when the current effect pattern designation command is received (S100), all of the effects are displayed. When the shielding plate 71 has not returned to the upper limit position (during the return processing of the shielding plate 71), no shutter origin error has occurred (S101: NO), and the motor 88 is not at the origin position (S102: NO) )

  Next, it is determined whether or not the motor 88 has returned to the origin by an origin sensor (not shown) (S105). As a result, when it is determined that the motor 88 has not returned to the origin even though the origin return process (S104) is executed (S105: NO), the shutter origin error flag is set and the shutter origin error is set. Is generated (S106), the operation of the motor 88 is stopped (S107), and the shutter control process is terminated as it is.

  If it is determined in S102 that the motor 88 is at the origin (S102: YES), and if it is determined in S105 that the motor 88 has returned to the origin (S105: YES). Then, it is determined whether or not to perform a shutter effect (S108). As a result, when it is determined that the shutter effect is not performed (S107: NO), the shutter control process is ended as it is.

  On the other hand, when it is determined that the shutter effect is to be performed (S107: YES), the shutter effect process is started (S200). Here, the shutter effect process S200 will be described with reference to FIGS.

  At the start of the shutter effect process S200, the display area of the symbol display device 25 is in a fully open state that is not covered with the shielding plate 71 (FIG. 25A). At this time, in the display area (left / middle / right symbol display area) of the symbol display device 25, it is assumed that the variable display of the effect symbols (pseudo special symbols) has already started. By starting the operation of the motor 88 in this state (S201), the shielding plate 71 is lowered, and the display area of the symbol display device 25 is covered with the shielding plate 71 (FIGS. 25B and 25C). )).

  Until the shielding plate 71 moves to the lower limit position (until the transition from the fully open state to the fully closed state), screen display when the shielding plate is lowered is performed in the display area of the symbol display device 25 (S202, S203). The screen display when the shield plate is lowered continues the display of the effect symbols in the portion of the display area of the symbol display device 25 that is not covered by the shield plate 71, and the display color of the portion that is covered by the shield plate 71 is displayed. Is made plain black (first display color). In the screen area of the symbol display device 25, the black display also decreases as the shielding plate 71 descends, and the ratio of the black display increases, and the ratio of the variable display of the effect symbols decreases. As a result, the player gradually covers the display area of the symbol display device 25 with the shielding plate 71, and continuously displays the variation of the effect symbol in the portion not covered with the shielding plate 71. Can be recognized. At this time, the portion covered with the shielding plate 71 in the display area of the symbol display device 25 is displayed in black, so that no light is irradiated toward the back surface of the shielding plate 71 and light is transmitted through the decorative design 90. Never do. For this reason, the player cannot visually recognize the decorative symbol 90 without the color (blue) of the decorative symbol 90 changing.

  Then, after the shielding plate 71 has moved to the lower limit position, the operation of the motor 88 is stopped (S204). The operation of the motor 88 of this embodiment is controlled by the number of rotations (number of steps), and is configured to stop the operation of the motor 88 when the number of rotations (number of steps) of the motor 88 reaches a predetermined number. As a result, the lowering of the shielding plate 71 is stopped, and the entire display area of the symbol display device 25 is covered with the shielding plate 71 (FIG. 25D).

  Next, it is determined whether or not a shutter opening / closing effect is performed (S205). As a result, when it is determined that the shutter opening / closing effect is not performed (S205: NO), the process proceeds to S210. On the other hand, when it is determined that the shutter opening / closing effect is to be performed (S205: YES), the solenoid 80 is turned on to open the shielding plate 71 (S206). Then, until the shutter opening / closing effect is completed, screen display at the time of opening / closing the shielding plate is performed at a portion corresponding to the opened shielding plate 71 in the display area of the symbol display device 25 (S207, S208). Thereby, the site | part which the shielding board 71 open | released in the display area of the symbol display apparatus 25 becomes visible from a player (FIG.25 (e)). In the present embodiment, the design symbol for alphabet letters “ABC” is displayed in the display area of the design display device 25, but this is not restrictive, and a design symbol dedicated for opening and closing the shielding plate may also be displayed. Good. In the present embodiment, the two shielding plates 71 located at the center of the six shielding plates 71 are opened and closed. However, any one or more shielding plates 71 can be opened and closed according to the production mode. That's fine. In this embodiment, the shielding plate 71 is kept open, but the shielding plate 71 may be opened and closed repeatedly in a short time.

  When the shutter opening / closing effect ends, the solenoid 80 is turned off to close the shielding plate 71 (S209). As a result, the entire display area of the symbol display device 25 is fully covered with the shielding plate 71 (FIG. 25D).

  Next, it is determined whether or not to perform a decorative symbol effect using the decorative symbol 90 (S210). As a result, when it is determined that the decorative symbol effect is not performed (S210: NO), the process proceeds to S214.

  On the other hand, when it is determined that the decorative symbol effect is to be performed (S210: YES), the display color of the screen area of the symbol display device 25 is set to a plain white color (second display color) (S211). Thereby, the light emitted from the light source of the symbol display device 25 is applied to the shielding plate 71 through the display area of the symbol display device 25 and is transmitted through the decorative symbol 90. For this reason, the decorative pattern 90 of the lightning pattern appears as a pale color on the shielding plate 71, and the decorative pattern 90 becomes visible (FIG. 25 (f)). Then, upon completion of the decorative symbol effect, the display color of the screen area of the symbol display device 25 is changed to a solid black (first display color) (S212, S213). Thereby, the display of the decorative design 90 disappears from the shielding plate 71 (FIG. 25D).

  Next, when ending the shutter effect process, the operation of the motor 88 is started (S214, S215). Thereby, the shielding board 71 raises and the display area of the symbol display apparatus 25 covered with the shielding board 71 becomes gradually visible (FIGS. 25 (g) and 25 (h)). Then, until the shielding plate 71 moves to the upper limit position (until the transition from the fully closed state to the fully opened state), screen display when the shielding plate is raised is performed in the display area of the symbol display device 25 (S216, S217). The screen display when the shield plate is raised continues the black display in the portion covered by the shield plate 71 in the display area of the symbol display device 25, and the effect symbols are variably displayed in the portion not covered by the shield plate 71. Is done. In the screen area of the symbol display device 25, the black display also rises as the shielding plate 71 rises, the ratio of black display decreases, and the ratio of display of effect symbols increases. At this time, the portion covered with the shielding plate 71 in the display area of the symbol display device 25 is displayed in black, so that no light is irradiated toward the back surface of the shielding plate 71 and light is transmitted through the decorative design 90. Never do. For this reason, the player cannot visually recognize the decorative symbol 90 without the color (blue) of the decorative symbol 90 changing. In FIG. 25 (g), in the process of ascending the shielding plate 71, more than half of the display area of the symbol display device 25 is still covered with the shielding plate 71, and the effect symbol is displayed in the lower part of the display area. It shows a state that is visible. Also, in FIG. 25 (h), the shielding symbol 71 is further raised than in the state of FIG. 25 (g), and the effect symbol “7” is stopped and displayed in the left symbol display area of the symbol display device 25 that can be visually recognized. The remaining effect symbols (effect symbols displayed in the middle symbol display area and the right symbol display area) are variably displayed.

  Then, when the shielding plate 71 moves to the upper limit position, that is, when the rotation number (step number) of the motor 88 reaches a predetermined number, the operation of the motor 88 is stopped (S218). Thereby, the raise of the shielding board 71 stops and it will be in the fully open state where the whole display area of the symbol display apparatus 25 is not covered with the shielding board 71 (FIG.25 (i)). At this time, the display mode of the symbol display device 25 is that the same symbol “7” for the effect is stopped and displayed in the left symbol display area and the right symbol display area respectively, and the effect symbol is variably displayed in the middle symbol display area. Reach reach state, and then reach effect display is performed.

  In this way, by performing the notice effect using the shutter device 70 from the start of the change of the effect design (pseudo special symbol) to the start of the reach effect display, the notice effect without using the shutter device 70 is achieved. Compared with this, the player's sense of expectation for the big hit can be further enhanced, and the gaming interest can be further enhanced. Also, as the operation mode of the shutter device 70, various operation modes corresponding to the effect pattern designation command transmitted from the main control unit 200 are set in advance, so that various shutter effects using the shutter device 70 are made. be able to.

  In the present embodiment, as a shutter effect process using the shutter device 70, a description has been given of an example of a notice effect that is performed with the start of variable display of the effect symbol (pseudo special symbol) in the symbol display device 25. The shutter effect process can be applied to various effects other than the notice effect. For example, a demonstration effect when no game is played by a player, a reach effect that is performed after the design symbol (pseudo special symbol) is in a reach state, and a jackpot fanfare effect that is performed at the start of a special game state (big hit) , A jackpot round effect during a round game in a special game state, a jackpot round effect between the end of one round and the start of the next round, a jackpot ending effect performed at the end of a special game state (bonus) Applicable to etc.

  As described above, in a gaming machine capable of switching between a fully open state where the shielding plate 71 does not exist on the front side of the symbol display device 25 and a fully closed state where the front side of the symbol display device 25 is shielded by the shielding plate 71. In the state, the symbol display device 25 displays the effect symbol, and when shifting from the fully open state to the fully closed state, the symbol display device 25 displays the screen in conjunction with the lowering of the shielding plate 71, and the fully closed state. By performing screen display using decorative symbols, it is possible to perform effect control that links the movement of the shielding plate 71 and the display of the symbol display device 25 from the fully open state to the fully closed state. Thereby, the production | generation which united the image and movable object which are not in the past can be performed, and various production | presentation aspects can be implement | achieved. Furthermore, when shifting from the fully closed state to the fully open state, the symbol display device 25 performs screen display in conjunction with the ascent of the shielding plate 71, thereby interlocking the movement of the shutter device 70 and the display of the symbol display device 25. It is possible to smoothly shift from the rendered effect to an effect using only the effect display of the symbol display device 25.

  Further, in the fully closed state, the shielding plate 71 is opened and closed, and the effect display is performed at a portion corresponding to the opened shielding plate 71 in the symbol display device 25, so that the complicated movement of the shielding plate 71 and the display on the symbol display device 25 are displayed. Can be performed in conjunction with each other, and more various effects can be realized. Furthermore, by making a part of the shielding plates 71 open and the other shielding plates 71 closed, the effect display performed on the screen by the symbol display device 25 can be partially visually recognized by the player. This makes it possible to produce a novel production.

(Second embodiment)
Next, a second embodiment of the present invention will be described. The second embodiment differs from the first embodiment in the configuration of the shutter device 70. Only the parts different from the first embodiment will be described below.

  FIG. 26 is a perspective view showing the internal configuration of the shutter device 70 of the second embodiment. FIG. 26 shows a state where the shutter device 70 shields the front side of the symbol display device 25 and the screen of the symbol display device 25 is invisible. Although not shown in FIG. 26, a colorless and transparent cover member is provided on the front side of the shutter device 70 so as to cover the entire periphery of the shielding plate 71.

  In the shutter device of the second embodiment, guide shafts 72 extending in the arrangement direction of the plurality of shielding plates 71 (vertical direction in FIG. 26) are provided on both outer sides of the shielding plate 71. A shield plate guide 73 is slidably provided on the guide shaft 72 corresponding to each shield plate 71. An end portion of the shielding plate 71 is connected to the shielding plate guide 73 via a connecting arm 74. The connecting arm 74 connected to each shielding plate 71 is connected to the connecting arm 74 connected to the adjacent shielding plate 71. A slide member 75 is provided at the lower end of the guide shaft 72. A guide shaft 72 passes through the slide member 75, and the slide member 75 is slidable along the guide shaft 72. The slide member 75 slides along the guide shaft 72 to move the shielding plate 71 upward via the connecting arm 74.

  A lead screw 76 for moving the slide member 75 along the guide shaft 72 is provided on both outer sides of the shielding plate 71. The lead screw 76 is provided so as to penetrate the slide member 75, and the slide member 75 is movable in the vertical direction along the lead screw 76. The lead screw 76 is a male screw having a spiral unevenness formed on the outer peripheral surface, and the slide member 75 is a female screw having a groove that meshes with the concave and convex portions on the outer peripheral surface of the lead screw 76 on the inner peripheral surface of the penetrating portion. It has become.

  A motor 77 as a driving means is provided below each lead screw 76, and the lead screw 76 is rotationally driven by the motor 77. Each motor 77 provided on the two lead screws 76 is configured to rotate synchronously.

  The first sensor 78 is provided near the upper end of the guide shaft 72, and the second sensor 79 is provided near the lower end of the guide shaft 72. The first sensor 78 is provided at an upper limit position in a range in which the slide member 75 moves along the guide shaft 72 and detects that the slide member 75 has reached the upper limit of the movable range. The second sensor 79 is provided at a lower limit position in a range in which the slide member 75 moves along the guide shaft 72 and detects that the slide member 75 has reached the lower limit of the movable range.

  Next, the movement of the shielding plate 71 of the shutter device 70 of the second embodiment will be described. FIG. 27 is a perspective view of the shutter device 20. FIG. 27 shows a case where all the shielding plates 71 are moved upward, the shutter device 70 is fully opened, and the symbol display device 25 is visible.

  When the lead screw 76 is rotationally driven by the motor 77, the slide member 75 moves in the vertical direction along the lead screw 76. As a result, the slide member 75 moves upward along the guide shaft 72 and pushes up the connecting arm 74. The connecting arm 74 is folded in the process of being pushed up by the slide member 75, and moves upward in a state where all the shielding plates 71 connected to the connecting arm 74 are overlapped. As a result, all the shielding plates 71 move upward from the screen of the symbol display device 25, and as shown in FIG. 27, the shielding plate 71 does not exist on the front side of the screen of the symbol display device 25 (fully open state). Become.

  Further, by rotating the motor 77 in the reverse direction, the slide member 75 moves downward, and the shielding plate 71 moves downward due to its own weight. At this time, the folded connection arm 74 extends, and the overlapping shielding plates 71 are unfolded one by one on the front side of the symbol display device 25. Thereby, all the shielding plates 71 are moved to the front side of the symbol display device 25, and the front side of the screen of the symbol display device 25 is covered with the shielding plate 71 (fully closed state).

  Next, the opening / closing mechanism of the shielding plate 71 of the shutter device 70 in the second embodiment will be described. FIG. 28 is a perspective view showing a state in which all the shielding plates 71 in the shutter device 70 are opened and the screen of the symbol display device 25 is in a visible state, and FIG. It is explanatory drawing for doing.

  As shown in FIG. 29, on one side (one short side) of each of the six shielding plates 71, the shielding plate 71 is actuated by receiving a rotation shaft 71 a serving as a rotation center of the shielding plate 71 and an external force. A working shaft 71b is provided. The rotating shaft 71a is provided slightly deviated from the center position on the side of the shielding plate 71. When no external force is applied to the shielding plate 71, the shielding plate 71 is in a vertical state. The rotating shaft 71a and the operating shaft 71b are provided corresponding to the number of solenoid arms 81, but in order to avoid complicated description in FIG. 29, the uppermost shielding plate among the six shielding plates 71. The rotation shaft 71a and the action shaft 71b provided in 71 are illustrated, and illustration of the rotation shaft 71a and the action shaft 71b provided for the remaining five shielding plates 71 is omitted.

  The action shaft 71 b is provided at an end portion on one side of the shielding plate 71. The tip of the solenoid arm 81 is located above the action shaft 71b. The other end side of the solenoid arm 81 is connected to the solenoid slider 82. The other end sides of the two solenoid arms 81 arranged in the vertical direction are connected to the same solenoid slider 82. The solenoid slider 82 is connected to the movable iron core of the solenoid 80. By switching the solenoid 80 on and off, the solenoid slider 82 moves in the vertical direction, and the tips of the two solenoid arms 81 move in the vertical direction.

  When the solenoid 80 is not energized, the tip of the solenoid arm 81 is located above the action shaft 71b of the shielding plate 71, and the shielding plate 71 is closed (see FIG. 26). At this time, it becomes an invisible state where the screen of the symbol display device 25 cannot be seen from the front side of the gaming machine 1.

  When the solenoid 80 is energized and turned on, the tip of the solenoid arm 81 pushes down the action shaft 71b of the shielding plate 71 (see the solenoid arm 81 represented by a broken line in FIG. 29). As a result, the shielding plate 71 rotates around the rotation shaft 71a to change from the vertical state to the horizontal state, and the shielding plate 71 is opened (see FIG. 28). At this time, it becomes a visible state in which the screen of the symbol display device 25 can be seen from the front side of the gaming machine 1.

  Also with the above-described configuration of the shutter device 70, the same effects as those of the first embodiment can be obtained.
