That is, the rotating plate 30 is rotated by the driving force of the motor 32 via the spur gear 34 b, the worm wheel 34 and the worm gear 33. The rotating plate 30 is a main configuration of a driving mechanism that moves the LCD 10 and the half mirror 20. By using the worm gear mechanism described above to transmit the rotational force of the motor 32 to the rotating plate 30, the rotating plate 30 has a compact configuration. A large ratio can be obtained, and even a low output motor can obtain a larger torque. In addition, since the motor 32 is arranged in the tangential direction of the worm wheel 32 and the width between the motor 32 and the worm gear mechanism can be reduced, the side plate 1b is provided on the side plate 1b as in this embodiment as compared with the case where a spur gear mechanism is employed. It can arrange | position without extending too much along.

  A cam groove 30 b is formed on the outer side surface of the rotating plate 30. The cam groove 30b is a cam groove for detecting the rotational position of the rotating plate 30. Specifically, a pair of sensors 41 a and 41 b are disposed on the fixing plate 31 a of the drive source unit 31. In the case of the present embodiment, the sensors 41 a and 41 b are optical sensors and detect the presence or absence of the detected piece 40 b provided at one end of the sensor arm 40. The sensor arm 40 is a plate-like member that is rotatably supported by a shaft 34a, and a pin-like sliding portion 40a is provided at the other end. When the rotating plate 30 rotates, the sliding portion 40a slides in the cam groove 30b, and is guided by the cam groove 30b to rotate the sensor arm 40 around the shaft 34a. The sensors 41a and 41b are respectively arranged so as to correspond to two positions (first and second positions described later) of the LCD 10, and the position of the detected piece 40b is moved by the rotation of the sensor arm 40. When detected by the sensor 41a, it is detected that the LCD 10 is present at the second position, and when detected by the sensor 41b, it is detected that the LCD 10 is present at the first position. That is, the sensors 41a and 41b function as sensors that detect the position of the LCD 10.

  Next, a spur gear 35 that meshes with the rotating plate 30 is provided on the side plate 1b. The spur gear 35 is fixed to a shaft 35a penetrating between the side plates 1b-1c. The shaft 35a is rotatably supported by the side plates 1b and 1c and is disposed substantially horizontally. The spur gear 35 and the shaft 35a are for transmitting the driving force of the motor 32 to the driving mechanism on the side plate 1c side. FIG. 4B is a left side view of the image display unit 1. Except for the drive source unit 31, the side plate 1c side is provided with the same mechanism as the side plate 1b side, and the rotational force of the shaft 35a is transmitted to the side plate 1c side rotating plate 30 via the side plate 1c side spur gear 35. Will be. In FIG. 4B, the same reference numerals are given to the configurations corresponding to the configuration of FIG. In this embodiment, the design is reduced and the types of parts are reduced by adopting the same configuration on both side plates except for the drive source unit 31 in this way. In addition, since it is the same structure on the both-sides board side, below, a drive mechanism is demonstrated by the structure by the side board 1b side.

An arm member 14 is rotatably attached to the side plate 1b. The arm member 14 constitutes a part of a mechanism for moving the LCD 10. Details of these will be described later. The arm member 14 has a locking portion 14b to which one end of a spring 15 is locked, and the other end of the spring 15 is locked to a locking portion 1a "formed on the top plate 1a. When the member 14 rotates in one direction, it assists the rotation, and when it rotates in the other direction, it functions as an elastic member that resists the rotation. The LCD 10 moves (rotates) between the first position and the second position. At this time, the load of the motor 32 increases due to the weight of the LCD 10, and the movement from the first position to the second position occurs. In this case, the spring 15 assists the rotation of the arm member 14, and the spring 15 resists the rotation of the arm member 14 when the LCD 10 moves from the second position to the first position. This adjusts the load on the motor 32. It is possible to become.

The axis of the shaft 12 is set to the horizontal direction, and the LCD 10 is supported so as to be rotatable about a horizontal axis defined by the shaft 12.

  The side plate portion 13a is provided with a long hole-shaped guide portion 13c extending vertically. The guide portion 13c is for guiding the movement of the LCD 10, and the sliding portion 14c of the arm member 14 engages and slides on the guide portion 13c in addition to the guide portion 16 of the side plate 1b. That is, the sliding portion 14c passes through the guide portions 16 and 13c, penetrates the side plate 1b and the side plate portion 13a, and functions as an engaging member that engages the driving mechanism and the LCD 10 (bracket 13). In other words, the sliding portion 14c is a connecting member that connects the driving mechanism and the LCD 10 (the bracket 13).

  Next, a half mirror 20 is disposed behind the LCD 10. Support frames 21 that support the half mirror 20 are attached to both sides of the half mirror 20. FIG. 7A is an exploded view of the half mirror 20 and the support frame 21. The support frame 21 is provided with four holes 21a to 21b. The front ends of the shaft bodies 23a and 23b of the auxiliary plate 23 are inserted into and engaged with any two of the four holes 21a to 21b, and the support frame 21 and the auxiliary plate 23 are integrated with the side plate 1b. Will be installed. In FIG. 6A, the tips 23 a ′ and 23 b ′ of the shaft bodies 23 a and 23 b of the auxiliary plate 23 are inserted into the holes 21 b and 21 c of the support frame 21 and engaged. In addition, as shown in FIG.7 (b), the four holes 21a thru | or 21b are arrange | positioned symmetrically with respect to the linear point which passes along the center of the support frame 21, and have the shape used as right-and-left sharing. . Accordingly, as shown in FIG. 7 (a), the support frames 21 having the same configuration are attached to both sides of the half mirror 20 in different directions. In this way, it is sufficient to prepare one type of support frame 21.

<Movement operation>
Next, a movement mode of the LCD 10 and the half mirror 20 by the above drive mechanism will be described. FIG. 8A and FIG. 9A are explanatory diagrams of a movement mode of the LCD 10 and the half mirror 20, and are views of main structures of the LCD 10, the half mirror 20, and the above drive mechanism as viewed from the right side. FIG. 8B and FIG. 9B are explanatory views of the movement mode of the shielding member 17, and are views of the shielding member 17 and the like viewed from the right side.

  First, in FIG. 8A (a), the LCD 10 is in a state where its display screen 11 is substantially vertical and is exposed to the front of the image display unit 1. This is called the first position. This first position is a position where the half mirror 20 is hidden behind the LCD 10 when the image display unit 1 is viewed from the front, and the display surface of the image display unit 1 is the display screen 11 of the LCD 10. In other words, the LCD 10 becomes a direct display subject. The LCD 10 rotates about 90 degrees around the axis 12 in the rear direction as will be described. For this reason, in the state of FIG. 8A (a), the half mirror 20 is located at a position (retracted position) on the farther side of the image display unit 1 in order to avoid interference with the LCD 10. 8A (a), the shielding member 17 is in the position shown in FIG. 8B (a), the guide hole 16 is not shielded, and at least half of the guide holes 24a and 24b are shielded. . In the state shown in FIG. 8A (a), the LCD 10 is exposed from the front of the image display unit 1, so that the inside of the storage box is hardly visible to the player due to its presence, and the guide holes 16, Even if light enters from the outside into the storage box through 24a and 24b and the brightness in the storage box changes, the display image on the LCD 10 is not significantly affected.

  FIG. 8A (b) is a diagram showing a state in which the rotating plate 30 is rotated approximately 90 degrees counterclockwise. As the rotating plate 30 rotates, the sliding portion 14d slides along the cam groove 30c, and the arm member 14 rotates clockwise around the shaft 14a by the guide of the cam groove 30c. The position of the sliding portion 14c is moved by the rotation of the arm member 14, and the sliding portion 14c slides on the guide portion 16 of the side plate 1b and the guide portion 13c of the bracket 13. Since the sliding portion 14c moves in an arc around the shaft 14a, the bracket 13 rotates counterclockwise around the shaft 12 by the sliding of the bracket 13 to the guide portion 13c. The LCD 10 supported by the bracket 13 also rotates counterclockwise. Although not shown, when the LCD 10 is in the first position, the spring 15 is extended beyond the natural length, and the contraction force urges the LCD 10 to rotate counterclockwise. .

  In the state of FIG. 8A (b), the half mirror 20 hardly moves. As can be seen from the shape of the cam groove 30d, the shape of the cam groove 30d is set so that the distance between the sliding locus of the sliding portion 22c and the rotation center (the shaft 30a) of the rotating plate 30 is substantially constant. Because. Further, as shown in FIG. 8B (b), the shielding member 17 is hardly moved.

  FIG. 9A (a) is a view showing a state in which the rotating plate 30 is further rotated approximately 90 degrees counterclockwise. The clockwise rotation of the arm member 14 further proceeds, and the LCD 10 is rotated to a position where the orientation of the LCD 10 is substantially horizontal. In this state, although not shown, the spring 15 is close to the natural length, and the biasing force of the counterclockwise rotation of the LCD 10 due to the contraction force is also small. In the state of FIG. 9A (a), the movement of the half mirror 20 is also progressing. As the rotating plate 30 rotates, the sliding portion 22c slides along the cam groove 30d, and the arm member 22 rotates clockwise around the shaft 22a by the guide of the cam groove 30d. The position of the locking portion 22b is moved by the rotation of the arm member 22, and presses the shaft body 23a.

  The auxiliary plate 23 moves together with the support frame 21 by being biased by the pressing of the shaft body 23a, and as a result, the half mirror 20 moves. The shaft bodies 23a and 23b are guided by the guide portions 24a and 24b of the side plate 1b to move the half mirror 20 to the front side of the image display unit A. At this time, in this embodiment, since the two guide portions 24a and 24b are provided and the shaft bodies 23a and 23b are slid, respectively, the posture of the half mirror 20 can be changed instead of simply moving. . That is, the posture when the half mirror 20 is moved is defined by the guide portions 24a and 24b. In the state of FIG. 9A (a), it turns out that the attitude | position of the half mirror 20 is sleeping than the state of FIG. 8A (a). On the other hand, as shown in FIG. 9B (a), the shielding member 17 hardly moves. However, the shaft body 23a substantially reaches the bent portion of the cam hole 17b. From this, the shielding member 17 moves (rotates) greatly.

  FIG. 9A (b) is a diagram illustrating a state in which the rotating plate 30 is further rotated counterclockwise by approximately 90 degrees, and illustrates a state in which the movement of the LCD 10 and the half mirror 20 is completed. The arm member 14 is directed substantially in the vertical direction, and the posture of the LCD 10 is substantially horizontal. This position of the LCD 10 is referred to as a second position. The display screen of the LCD 10 is substantially horizontal and faces directly below. In this state, a line connecting the rotation center of the arm member 14 (the shaft 14a) and the axis of the sliding portion 14c is oriented in a substantially vertical direction. Therefore, the rotational moment received by the arm member 14 due to the weight of the LCD 10 is substantially zero, and the arm member 14 makes it easier to maintain the stationary state of the LCD 10. Although not shown, the spring 15 has a substantially natural length, and the rotational moment received by the arm member 14 by the spring 15 is also substantially zero.

  The movement amount of the LCD 10 is small between FIG. 9A (a) and FIG. 9A (b). As can be seen from the shape of the cam groove 30c, the shape of the cam groove 30c is set so that the distance between the sliding locus of the sliding portion 14d and the rotation center (the shaft 30a) of the rotating plate 30 is substantially constant. Because. That is, when the LCD 10 is moved from the first position to the second position, the movement amount of the LCD 10 is increased in the first half, and the movement amount of the half mirror 20 is increased in the second half, thereby preventing interference between the two. It is.

  In the state of FIG. 9A (b), the half mirror 20 is moved to the front side of the image display unit 1 larger than the retracted position, and is positioned almost directly below the LCD 10. Also, the posture is more slanted than in the retracted position, and has an inclination of approximately 45 degrees with respect to the horizontal plane. The position of the half mirror 20 is referred to as a display position. When in this display position, the half mirror 20 is exposed to the front of the image display unit 1. The LCD 10 in the second position projects an image on the half mirror 20, and the half mirror 20 becomes a display surface of the image display unit 1. In other words, the LCD 10 is an indirect display subject, and the half mirror 20 is a direct display subject.

  On the other hand, in the state of FIG. 9A (b), the shielding member 17 is also moved as shown in FIG. 9B (b). The shielding member 17 rotates in a clockwise direction in conjunction with the movement of the shaft body 23a as the shaft body 23a slides on the cam hole 17b. The shielding member 17 shields at least the lower half of the guide hole 16, most of the guide hole 24a, and about half of the guide hole 24b. Since the LCD 10 has moved, the inside of the storage box can be easily seen by the player. In particular, since the lower half of the guide hole 16 is located on the front side, it may be visible to the player.

  However, in this embodiment, since the guide hole 16 is shielded by the shielding member 17 except for a part of the side of the LCD 10 (and the bracket 13), the LCD 10 (and the bracket 13) and the shielding member 17 protect the player from the player. The guide hole 16 is shielded, and the appearance inside the storage box can be improved. Further, when external light is inserted into the storage box through the guide hole 16, the surroundings of the half mirror 20 are unintentionally brightened, and the image displayed by the half mirror 20 becomes difficult to see from the player, The mirror 20 may be reflected by light, but the guide holes 16, 24 a and 24 b are almost shielded by the shielding member 17, etc., so that light insertion is minimized and the brightness in the storage box is reduced. Unintentional changes can be prevented.

  In this manner, when the LCD 10 is in the first position, the half mirror 20 is moved to the retracted position, and when the LCD 10 is in the second position, the half mirror 20 is moved to the display position. Become. Moreover, the shielding member 17 also rotates in conjunction with it, and the place to shield changes. By interlocking the shielding member 17, the guide holes 16, 24a and 24b can be shielded according to the positions of the LCD 10 and the half mirror 20 without obstructing the movement of the shaft bodies 23a and 23b and the sliding portion 14c.

  When returning from FIG. 9A (b) and FIG. 9B (b) to the state of FIG. 8A (a) and FIG. 8B (a), the motor 32 is reversed to rotate the rotating plate 30 in the reverse direction (clockwise). Thus, the LCD 10 moves in conjunction with the second position from the first position, and the half mirror 20 moves from the display position to the retracted position. At this time, since the spring 15 is gradually extended, it resists the counterclockwise rotation of the arm member 15. As a result, the load of the motor 32 can be made closer to a constant value when the LCD 10 is raised from the first position to the second position and when the LCD 10 is lowered from the second position to the first position.

  That is, since the LCD 10 is relatively heavy, the load on the motor 32 increases when the LCD 10 is moved from the first position to the second position, and conversely, when the LCD 10 is moved from the second position to the first position. Get smaller. On the other hand, the spring 15 acts in a direction to bias the LCD 10 when it moves from the first position to the second position, and acts in a direction to resist it when it moves from the second position to the first position. become. Therefore, the load of the motor 32 can be adjusted by the spring 15, and the load of the motor 32 is further increased when moving from the first position to the second position and when moving from the second position to the first position. Can be close to constant. This has the merit that the movement speed can be easily controlled.

  Further, in the present embodiment, as the half mirror 20 moves from the display position to the retracted position, the half mirror 20 is moved so that the posture thereof stands (inclination angle increases) (reversely, the retracted position from the display position to the retracted position). As the user moves to the position, the posture is moved to sleep (so that the inclination angle becomes smaller). Although the half mirror 20 may be moved in parallel, the length of the image display unit 1 in the depth direction can be further shortened by preventing the interference between the LCD 10 and the half mirror 20 by tilting the half mirror 20 at the retracted position. There is an effect, and the amount of movement of the half mirror 20 in the depth direction can be reduced.

<Position detection of LCD 10>
Next, the position detection of the LCD 10 will be described with reference to FIG. Although the position detection of the LCD 10 can be performed by various methods, in the present embodiment, as described above, the position detection of the LCD 10 is performed by the sensors 41a and 41b, and the LCD 10 is in the first position or the second position. Detect if there is. The position of the LCD 10 corresponds to the rotation angle of the rotating plate 30. Accordingly, the position of the LCD 10 can be detected by detecting the rotational position of the rotating plate 30.

  First, FIG. 10A shows a state when the LCD 10 is in the first position. At this time, the detected piece 40b of the sensor arm 40 is located in the vicinity of the sensor 41b, and its presence is detected by the sensor 41b. That is, it is detected that the LCD 10 is in the first position. FIG. 10B is a view showing a state in which the rotating plate 30 is rotated approximately 90 degrees counterclockwise. The position is changed by the sliding portion 40a being guided by the cam groove 30b, and the sensor arm 40 is rotated around the shaft 34a. As a result, the detected piece 40b moves up and moves away from the sensor 41b, and is positioned between the sensors 41a and 41b. Since both the sensors 41a and 41b do not detect the detected piece 40b, it is detected that the LCD 10 is moving.

  FIG. 10C is a view showing a state in which the rotating plate 30 is further rotated approximately 90 degrees counterclockwise. The sensor arm 40 hardly rotates, and the detected piece 40b remains positioned between the sensors 41a and 41b. As can be seen from the shape of the cam groove 30b, the shape of the cam groove 30b is set so that the distance between the sliding locus of the sliding portion 40a and the rotation center (shaft 30a) of the rotating plate 30 is substantially constant. Because.

  FIG. 10D is a view showing a state in which the rotating plate 30 is further rotated approximately 90 degrees counterclockwise. The position is changed by the sliding portion 40a being guided by the cam groove 30b, and the sensor arm 40 is rotated around the shaft 34a. As a result, the detected piece 40b rises and is positioned in the vicinity of the sensor 41a, and its presence is detected by the sensor 41a. That is, it is detected that the LCD 10 is in the second position.

<Rotation center of LCD 10>
Next, the setting of the rotation center (axis 12) of the LCD 10 will be described with reference to FIG. In the present embodiment, the rotation center (axis 12) of the LCD 10 faces a direction substantially orthogonal to the width direction of the LCD 10 and is displaced from the center line of the width of the LCD 10 (displaced to the front side of the image display unit 1). Position). Thereby, the length of the image display unit 1 in the depth direction can be further shortened. Specifically, if the rotation center of the LCD 10 is set on the center line of the width of the LCD 10 (point C in the figure), the rotation locus of the lower end portion of the LCD 10 is a broken line N shown in FIG. On the other hand, in the case of the present embodiment, the turning locus of the lower end portion of the LCD 10 is a broken line M shown in FIG. 6B, and when the LCD 10 is in the second position (position indicated by the broken line), the LCD 10 is moved by the distance d. It will be located on the front side. Therefore, the length of the image display unit 1 in the depth direction can be further shortened.

<Cam groove shape>
As described above, it is desirable to design the load of the motor 32 to be constant as much as possible. On the other hand, in the configuration of the present embodiment, when the LCD 10 is rotated, the load on the motor 32 varies greatly depending on the rotation angle. Specifically, when the LCD 10 shown in FIG. 8A is tilted by about 45 degrees, the torque of the rotating plate 30 is maximized, and thus the load of the motor 32 is also maximized. FIG. 12B is a diagram showing the relationship between the torque (cam torque) received by the rotating plate 30 and the rotation angle (cam angle) of the rotating plate 30, and the rotation plate 30 when the LCD 10 is in the first position. The rotation angle is 0. FIG. 12C is a diagram illustrating the relationship between the tilt angle (liquid crystal angle) of the LCD 10 and the cam angle.

  “Normal” indicated by a broken line indicates a case where the cam groove 30 c is designed in consideration of only the movement locus of the LCD 10. It can be seen that the cam torque is maximum when the angle of the LCD 10 is around 45 degrees.

  Therefore, the cam groove 30c is perpendicular to the tangential line of the cam groove 30c at a portion where the load of the motor 32 is higher than at least a portion where the load of the motor is lower, and the sliding portion 14d By forming the distance between the line passing through the contact point with the cam groove 30c and the rotation center (shaft 30a) of the rotating plate 30 to be short, the load of the motor 32 can be made constant as much as possible. FIG. 12A is an explanatory diagram of the torque of the rotating plate 30.

  The torque of the rotating plate 30 is determined by the reaction force received from the sliding portion 14d and the distance between the reaction force and the shaft 30a. This reaction force is orthogonal to the tangent line (line K1) of the contact point between the sliding portion 14d and the cam groove 30c, and is directed in the direction passing through the contact point (line K2). Therefore, if the distance D between the line K2 and the line K3 parallel to the line K2 and passing through the shaft 30a can be reduced, the torque of the rotating plate 30 can be reduced. Therefore, in the cam groove 30c, the cam surface is designed so that the line K2 passes as close as possible to the shaft 30a in the portion where the torque is high, and the line K2 passes as far as possible from the shaft 30a in the portion where the torque is low. By designing the cam surface, the load of the motor 32 can be made constant and the life of the motor 32 can be extended. In general, the torque and the rotational speed are inversely proportional to each other due to the characteristics of the motor. However, in the present embodiment, the maximum torque of the motor 32 is reduced, so that the rotational speed can be increased accordingly, and the LCD 10 and the half mirror 20 are moved. Speed can be improved.

  “Improvement” indicated by a solid line in FIGS. 12B and 12C is an example, and the cam torque peaked in the case of “normal”, the cam torque in the vicinity of the cam angle of 95 degrees is reduced, and conversely It can be seen that the cam torque near the angle of 130 degrees is increased. In addition, the transition of the angle of the LCD 10 with respect to the cam angle is slightly different from “normal” (FIG. 12C), but there is no great difference, and there is no problem in the movement of the LCD 10.

<Image display mode>
Next, an image display mode of the image display unit 1 will be described with reference to FIG. FIG. 11 is an explanatory diagram of the principle of displaying a three-dimensional image by the image display unit 1, and the diagram on the right side of FIG. 11 is a diagram of the main part of the image display unit 1 as viewed from the side. Indicates a display image that is visible to the player when the LCD 10 is in the second position. In the example of the figure, a three-dimensional object X is disposed behind the half mirror 20. The three-dimensional object X is a model simulating a mountain.

  Now, when the LCD 10 is in the position of the broken line (first position) in the figure, as described above, the display screen 11 of the LCD 10 is exposed to the front of the image display unit 1, and the display screen 11 is displayed from the player. However, the half mirror 20 is in the retracted position (indicated by a broken line) and is hidden behind the LCD 10 and cannot be seen. From the image display unit 1, a two-dimensional image by the LCD 10 is presented to the player.

  On the other hand, when the LCD 10 is at the solid line position (second position) in the figure, the LCD 10 is substantially horizontal, so the player cannot directly see the display screen 11. And the half mirror 20 exists in the display position shown as a continuous line, and the image (virtual image) projected on the half mirror 20 from LCD10 is shown to a player. As seen from the player, this virtual image appears to be floating behind the half mirror 20 and becomes a three-dimensional image with a three-dimensional feeling. The position of the virtual image is determined by the distance (L1, L2) between the LCD 10 and the half mirror 20 and the angle between the LCD 10 and the half mirror 20 (approximately 45 degrees in this example). A virtual image can be seen at a position away from 20 by L1 and L2 in the depth direction.

  In the example of FIG. 11, the three-dimensional object X is arranged behind the half mirror 20 and behind the virtual image position in the player's visual recognition direction. The three-dimensional object X passes through the half mirror 20 as a real image and is visible to the player. For this reason, in the display image shown on the left side of the figure, a virtual image (UFO) and a three-dimensional object X are combined and are viewed in the order of virtual image (UFO) → three-dimensional object X when viewed from the player. looks like. The presence of the three-dimensional object X enhances the sense of depth, resulting in a further three-dimensional image.

  FIG. 32A is a display image example that more realistically represents the composite image, where the image of the king's face and a gentleman with diamonds is a virtual image, and the other is a model arranged behind the half mirror 20. It is. In the example of the figure, a dark color is used as the color of the gentleman's image so that the model existing behind the virtual image is difficult to see through. FIGS. 32B and 32C are more realistic representations of examples of three-dimensional objects (models).

  As described above, according to the image display unit 1 of the present embodiment, a two-dimensional image and a three-dimensional image can be selectively provided, and an image display that surprises the viewer can be realized. In particular, since the half mirror 20 is disposed behind the LCD 10 at the first position, when the image display unit 1 is viewed from the front, the image display area of the LCD 10 at the first position and the image display area by the half mirror 20 are The two-dimensional image and the three-dimensional image are exchanged by the movement of the LCD 10. In addition, by moving the LCD 10 between the first and second positions, it is possible to display both a two-dimensional image and a three-dimensional image on one LCD 10, and it is not necessary to use a plurality of image display devices. Reduction can be achieved.

<Shutter unit>
Next, the configuration of the shutter unit 50 will be described. 13A is a front view of the shutter unit 50, and FIG. 13B is a right side view. The shutter unit 50 includes a left door 51a and a right door 51b (hereinafter, both are collectively referred to as the door 51). The left door 51a and the right door 51b are provided on the front surface of the image display unit 1 so as to be freely opened and closed, and constitute a pair of shielding members that shield the display image by the LCD 10 and the half mirror 20 from the player when the image display unit 1 is closed. . 2 and 3 and FIG. 13A, the left door 51a and the right door 51b are opened, and the display image by the LCD 10 and the half mirror 20 is located at a position (non-shielding position) visible to the player. When these are moved inward and are in the closed position (shielding position), the display image by the LCD 10 and the half mirror 20 is shielded from the player.

  The shutter unit 50 has a frame 53 having an opening 53a at the center. The hook-like engaging portion 52 described above is formed in which a part of the upper end portion of the frame 53 is bent in a U shape and engages with an engaging piece on the upper portion of the frame body 180a. A hollow projection 53b (shown in cross section in FIG. 13B) is formed on the rear surface of the frame 53, and a slit 53b 'is formed in the projection 53b. The slits 53b ′ are respectively formed corresponding to the engaging portions 1b ″ and 1c ″ of the image display unit 1, and the engaging portions 1b ″ and 1c ″ are inserted as shown by broken lines in FIG. Engage. To release the engagement, the engaging portions 1b "and 1c" may be moved slightly upward and extracted from the slit 53b '. Thereby, the image display unit 1 and the shutter unit 50 are detachably attached to each other. By making them both detachable, the image display unit 1 and the shutter unit 50 can be individually designed, manufactured and assembled later, so that productivity is excellent and maintenance is facilitated.

  The frame 53 is provided with two pairs of upper and lower guide rail members (58a, 58b). Each of the guide rail members 58a and 58b has a U-shaped cross section, and the lower end portion and the upper end portion of the door 51 are fitted into the guide rail members 58a and 58b, respectively, and guide the parallel movement of the door 51 in the horizontal direction. The guide rail member 58a guides the door 51a, and the guide rail member 58b guides the door 51b.

  Next, driving means for moving the door 51 will be described. In this embodiment, a belt transmission mechanism is employed. By adopting the belt transmission mechanism, the door 51 can be moved quietly and smoothly. Although the left door 51a and the right door 51b are independently driven, since the drive means and the like have the same configuration, only the configuration of the drive means and the like of the right door 51b will be described here. In FIG. 13, each component of the left door 51 a corresponding to each component of the drive means and the like of the right door 51 b is given a reference numeral “a” at the end.

  The shutter unit 50 includes an endless belt 56b wound between a pair of pulleys 55b and a motor 54b that travels the endless belt 56b. The pulley 55b is a rotating body that is rotatably supported by the frame 53. One pulley 55b is connected to the output shaft of the motor 54b as a driving pulley. The motor 54 b is a stepping motor, for example, and is fixed to the back side of the frame 53. The right door 51b is attached to the endless belt 56b, and moves as the endless belt 56b travels. A pair of sensor units 57b for detecting the position of the right door 51b are attached to the frame 53 apart from each other in the moving direction of the right door 51b. When the right door 51b is detected by each sensor unit 57b, the endless belt 56b is driven by a predetermined amount by the motor 54b and then stopped, so that the right door 51b can be stopped at a predetermined position.

  FIG. 14A is a front view showing details of the configuration in the vicinity of the right door 51b, and FIG. 14B is a right side view. At the four corners of the right door 51b, a roller 60a that rotates about a horizontal axis and a roller 60b that rotates about a vertical axis are provided. These rollers 60a and 60b abut against the peripheral wall of the guide rail 58b in the guide rail 58b, and realize a smooth movement of the right door 51b.

  Above the right door 51b, an engaging portion is provided for detachably engaging the right door 51b with the endless belt 56b. In the case of this embodiment, this engaging part consists of the board 61a with which the edge part was rounded, and the tooth | gear part 61b above the board 61a. The tooth portion 61b is engraved with a tooth shape corresponding to the tooth shape provided on the endless belt 56b, and the endless belt 56b is inserted into the gap between the tooth portion 61b and the plate 61a from the side. The right door 51b can be engaged with the endless belt 56b by being sandwiched between the tooth portion 61b and the plate 61a.

The kind of winning combination can be arbitrarily adopted, but the following winning combination is adopted in the present embodiment. 20 (a) to 20 (c) are diagrams showing the types of winning combinations in each gaming state, the corresponding picture combinations, the number of medals paid out at the time of winning, and the winning probability of internal lottery. FIG. 20A shows the normal mode, FIG. 20B shows the big bonus game, and FIG. 20C shows the regular bonus game and the shift regular bonus game. There are setting 1 to setting 6 for the internal winning probability, and the attendant of the game hall can arbitrarily select any one. In the example of FIG. 20, one of settings 1 to 6 (indicated by setting N) is illustrated.

  The internal winning probability is explanatory data described for easy understanding of the explanation, and is specifically as follows. That is, the range of random values (0 to 65536) acquired at the time of the internal winning lottery is divided into several areas (areas proportional to each internal winning probability) in advance, Winning and loss are associated. These pieces of information are stored in the ROM 312 as a winning combination lottery table. In the internal lottery of the winning combination, whether or not the internal winning of the winning combination is determined according to which range the acquired random number value belongs. Hereinafter, each winning combination in the normal game will be described individually.

(1) Normal game ・ Big Bonus (BB):
A winning combination in which the gaming state is changed by winning, and in the case of this embodiment, a winning combination in which a big bonus game (BB game) is started. In this embodiment, a predetermined number (15 in this case) of medals is paid out when winning. There are two types of corresponding pattern combinations as shown in FIG. In this embodiment, flag carryover is performed for BB. Here, in this embodiment, when an internal winning is made for some winning combination, the corresponding internal winning flag is turned ON. The internal winning flag is set in a predetermined area on the RAM 313, and is turned OFF when the game ends, except when the flag is to be carried over. If the BB is won internally, even if the BB is not won in the game, the flag is kept until the BB is won, and the BB will be in the internal win even after the next game.

・ Regular Bonus (RB):
A winning combination in which the gaming state is changed by winning, and in the case of the present embodiment, a winning combination in which a regular bonus game (RB game) is started. In this embodiment, a predetermined number (15 in this case) of medals is paid out when winning. There is one type of corresponding pattern combination as shown in FIG. In the present embodiment, the above-described flag carryover is also performed for the RB.

・ Small character The predetermined number of medals will be paid out by winning a prize. In the case of this embodiment, small roles are a watermelon, a bell, and a cherry. Corresponding pattern combinations and the number of payouts are as shown in FIG. In the case of “cherry”, the design of the middle reel 112 and the right reel 113 may be any design.
・ Replay
The winning combination is a winning combination in which a game can be performed without inserting medals in the next game, and medals are not paid out. In the case of the present embodiment, the corresponding pattern combination is “replay-replay-replay”. In the case of the present embodiment, there are two types of internal winning probabilities of replay, a normal probability and a high probability, and one of them will be selected depending on whether or not a predetermined condition is met. To do.

(2) BB game (BB general game)
FIG. 20B is a diagram showing the types of winning combinations in the BB general game, the corresponding picture combinations, the number of medals to be paid out by winning, and the internal winning probability of each winning combination.
・ Shift Regular Bonus (SRB):
This is a winning combination that wins only during the BB game (more specifically, during the BB general game), and is a winning combination in which a shift regular bonus game (SRB game) is started by winning. In this embodiment, a predetermined number (here, one) of medals is paid out when winning. There is one type of corresponding pattern combination as shown in FIG.
・ Small role It is the same as in normal games, with watermelon, bell and cherry.

(3) RB game / SRB game FIG. 20C shows the types of winning combinations in the RB game and the SRB game, the corresponding picture combinations, the number of medals to be paid out by winning, and the internal winning probability of each winning combination. FIG. The winning combination in the RB game and the SRB game is only an accessory, and each game in the RB game and the SRB game is called an accessory game. The winning combination is a winning combination that is won only during the RB game and the SRB game, and a predetermined number (15 in this case) of medals is paid out by winning and the internal winning is performed with high probability. The game state is not changed. In addition, as shown in FIG.20 (c), the combination of a corresponding pattern is one type.

<Game state>
In this embodiment, the game state is roughly divided into a normal game, a BB game, and an RB game, and the BB game is further classified into a BB general game and an SRB game.
・ BB game:
Although the content of the BB game can be a plurality of types, in this embodiment, as described above, it is possible to win an SRB during the BB game, and when this is won, the SRB game is started. In order to distinguish the case where the BB game is in the SRB game from the case where it is not, the latter is referred to as a BB general game. There are a plurality of BB game end conditions. In the present embodiment, the BB game ends when the profit obtained by the player during the BB game exceeds a certain value. In addition to this, as an end condition of the BB game, for example, the game ends when the SRB game is consumed a predetermined number of times (for example, 3 times) or the BB general game is consumed for a predetermined number of times (for example, 30 times). You may do it.
・ RB game and SRB game:
In the case of this embodiment, the RB game and the SRB game have the same content. Although there are a plurality of types of contents of the RB game and the SRB game, in the case of the present embodiment, a predetermined number of times (in this embodiment, 12 times) of an accessory game is consumed, or the number of times an accessory is determined in advance. (In this embodiment, 8 times) A game whose end condition is that any one of the conditions for winning a prize is satisfied. The number of times of winning of the bonus game and the number of winnings of the bonus game are managed by a software counter set in a predetermined area on the RAM 313.

<Reel stop control>
Next, stop control of the reels 110 to 112 will be described. The reel stop control is selected and selected from a plurality of predetermined reel stop control data based on selection conditions such as an internal lottery result, a gaming state, and whether a BB or RB flag is carried over. Perform based on reel stop control data. If multiple types of reel stop control data are set for the same condition, one of them is selected by lottery.

  In this embodiment, so-called pull-in control (frame slip control) is performed. The pull-in control refers to a control for shifting the stop positions of the reels 110 to 112 within a certain number of frames (for example, a maximum of 5 frames) after the player operates the stop buttons 131a to 131c. The reel stop control data is stored in the ROM 312 of the main control unit 300. Each reel stop control data is a control that allows a pattern combination of a predetermined winning combination to be displayed on the winning line 114 and a control that does not display any winning combination pattern combination on the winning line 114. It is roughly divided into

  Examples of the case where the former control is performed are, for example, a case where a winning combination is won internally, or a case where BB or RB is won internally (flag carryover), and each stop button 131a to 131c is operated by the player. Control is performed so that the winning combination of the winning combinations is displayed within the range of the number of frames, even if the timing of performing is poor. However, since it is only “permitted”, there are cases where the pattern combinations are not aligned depending on the timing of operating each of the stop buttons 13a to 131c. However, there is a case in which 100% is arranged depending on the arrangement of the patterns on the reels 110 to 112 and the number of drawn frames.

  An example where the latter control is performed is, for example, a case where the internal lottery result is lost and the BB or RB is not currently being won (flag carryover), and the timing at which the player operates the stop buttons 131a to 131c. Even if the quality is good, the control is performed so that the combination of the winning symbols is not displayed within the range of the number of frames.

<Setting of production contents>
Next, with reference to FIG. 21, a description will be given of setting the contents of effects executed in the slot machine 100. FIG. FIG. 21 is an explanatory view showing the basic setting of effect contents. The effect content is set by the sub-control unit 400 in accordance with a command transmitted from the main control unit 300. Hereinafter, a basic setting method will be described. In addition to those described below, corresponding production contents are set according to a control command (for example, a command indicating an error) from the main control unit 300.

  The contents of the production are divided into a plurality of groups, and one of them is selected in each game. In the present embodiment, an effect group is selected by a specific command (effect group selection in the figure) transmitted from the main control unit 300. The specific command is a command indicating the type of the above-described reel stop control data selected in the game. The production group can be selected by an independent lottery, but this lottery is also used depending on the type of reel stop control data. Since the reel stop control data is selected based on selection conditions such as the internal lottery result, the game state, and whether or not the BB or RB flag is carried over, it is possible to produce an effect in line with the game.

  Each effect group has an individual command from the main control unit 300 (in the example shown in FIG. 3, the operations on the stop buttons 131a to 131c (first to third stop operations, reel stop (first to third reel stop)). ), And is determined for each winning determination result (winning determination), and when the individual command is received, the corresponding effect data is selected, and the effect data is selected and executed even when the start lever is operated. However, since the command indicating the type of reel stop control data is transmitted at the start operation, it is selected and executed simultaneously with the selection of the effect group.

  The production data is set for each production device and stored in the ROM 412. When the sub-control unit 400 receives an individual command from the main control unit 300, the sub-control unit 400 reads the corresponding effect data and sets the data in each device. Thereafter, the contents of the set data are executed by each device. The production data includes a “control command”, which is a command for the production unit A. The sub-control unit 400 transmits this control command to the rendering unit control unit 500, and the rendering unit control unit 500 controls the rendering unit A according to the received command.

<Setting of operation contents of production unit A>
Next, the setting of the control content of the effect unit A will be described with reference to FIG. FIG. 22A is a diagram showing control data of the rendering unit A stored in the ROM 512, and FIG. 22B is a diagram showing display control data of the LCD 10 stored in the ROM 531. When the production unit control unit 500 receives the control command described above from the sub-control unit 400, the production unit control unit 500 executes a process corresponding to the number indicated by the control command ("No." in FIG. 22A).

  In the control data shown in FIG. 22 (a), “processing order”, control details of the left door 51a (“left door”), and control details of the right door 51b (“right” according to the number indicated by the control command. Door ") and the control content of the LCD 10 (" liquid crystal display ") are set. For example, from the sub-control unit 400, No. When the control command 1 is received, the rendering unit control unit 500 first causes the LCD 10 to display the contents of the display control data 1 in the “processing order” 1. In detail, as shown in FIG. 1 display control data is acquired and a corresponding image is displayed on the LCD 10. Subsequently, in the “processing order” 2, the door 51 is fully opened.

  Further, for example, from the sub-control unit 400, No. When the control command 5 is received, the rendering unit control unit 500 first closes the door 51 in “processing order” 1. Subsequently, in the “processing order” 2, the LCD 10 is moved downward (first position). Further, for example, from the sub-control unit 400, No. When the control command 10 is received, the rendering unit control unit 500 first closes the door 51 in “processing order” 1. Subsequently, in the “processing order” 2, the LCD 10 is moved upward (second position). Further, for example, from the sub-control unit 400, No. When the control command 21 is received, the rendering unit control unit 500 first closes the door 51 in “processing order” 1. Subsequently, in the “processing order” 2, the LCD 10 is moved upward (second position). Then, the content of the display control data 2 is displayed on the LCD 10 in “processing order” 3. This becomes a three-dimensional image. In “processing order” 4, the door 51 is fully opened and a three-dimensional image is presented to the player. In this way, the operation of the rendering unit A is controlled.

<Basic control of games>
FIG. 23 is a flowchart showing the basic control of the game in the slot machine 100. Basic control of the game is performed mainly by the CPU 310 of the main control unit 300, and the processing shown in FIG. Hereinafter, this process will be described. When the power is turned on, first, initial processing is executed in S101. Here, various initialization processes are performed. In S102, medal insertion / start operation acceptance processing is executed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of inserted medals. It is not necessary to insert a medal when winning the re-game in the previous game. Also, it is checked whether or not the start lever 130 has been operated. If there is an operation of the start lever 130, the process proceeds to S104, and a control command indicating that the start lever 130 has been operated is output to the sub-control unit 400. To do. Details will be described later.

  In S103, the number of inserted medals is determined, and an effective pay line 114 is determined. In S104, the random number generated by the random number generator 311 is acquired. In S105, the winning combination lottery table stored in the ROM 312 is read according to the current gaming state, and the internal winning lottery of the winning combination is performed using this and the random value acquired in S104. As a result of the internal lottery, when any winning combination is won internally, the winning combination flag is turned ON as described above. In S106, reel stop control data is selected based on the internal lottery result and the like as described above. In addition, a control command indicating the type of the selected reel stop control data is transmitted to the sub-control unit 400.

  In S107, rotation of all reels 110 to 112 is started. In S108, the stop buttons 131a to 131c can be received. When any one of the stop buttons is pressed, any one of the reels 110 to 112 corresponding to the pressed stop button is selected as the reel stop control data selected in S106. Stop based on. When all the reels 110 to 112 are stopped, the process proceeds to S109. In S109, a winning determination is performed. Here, when a picture combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “watermelon-watermelon-watermelon” is arranged on the activated winning line 114, it is determined that the watermelon is won. In addition, the flag indicating the internal winning of each winning combination is reset. However, as described above, when BB and RB are not won, the internal winning flag is kept ON and is carried over to the next game transition. In S110, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out. In S111, game state control processing is performed. Details will be described later. As described above, one game is completed, and thereafter, the process proceeds by returning to S102 and repeating the above-described processing.

<Medal insertion / start operation acceptance processing>
Next, the medal insertion / start operation acceptance process in S102 will be described. FIG. 24 is a flowchart showing the medal insertion / start operation acceptance process in S102. In S121, the prescribed number is set. Here, the number of medals that can be inserted in the game is set, and in the case of the present embodiment, the number is one for the accessory game and three for the other games. In S122, it is determined whether or not a re-game is won in the previous game. If applicable, the process proceeds to S123, and if not, the process proceeds to S124. In S123, it is assumed that the same number of medals as the previous game are inserted in order to make it unnecessary to insert medals in the current game. In S124, an idle timer is set. The idle timer is a timer for counting the time during which the slot machine 100 is not playing a game. In S124, the idle timer is started to count.

  In S125, error processing is executed. Here, it is determined whether or not an error such as a medal insertion abnormality (medal clogging, fraud etc.) has occurred, and if an error has occurred, a control command indicating that fact is sent to the sub-control unit 400.

In S126, it is determined whether or not a medal has been inserted and has been received normally. If applicable, the process proceeds to S127, and if not, the process proceeds to S128. In S127, a command indicating that a medal has been inserted is transmitted to the sub-control unit 400. In S128, a medal insertion confirmation process is executed. Details will be described later. In S129, it is determined whether or not the start lever 130 has been operated. If applicable, a control command indicating that the start lever 130 has been operated is output to the sub-control unit 400, and the process ends. If not applicable, the process returns to S125.

<Medal insertion confirmation process>
Next, the medal insertion confirmation process in S128 will be described. FIG. 25 is a flowchart showing the medal insertion confirmation process in S128. In S131, it is determined whether or not the current medal insertion number is zero. The number of inserted medals is managed by a software counter set in a predetermined area on the RAM 313. If applicable, the process proceeds to S132, and if not, the process proceeds to S137. In S132, it is determined whether the time measured by the idle timer indicates that a predetermined time has elapsed. If applicable, the process proceeds to S133, and if not applicable, the process ends.

  In S133, it is determined whether or not the current idle flag is ON. The idle flag is set in a predetermined area on the RAM 313, and indicates whether or not the non-game is continued for a certain time. If applicable, the process is terminated. If not applicable (OFF), the process proceeds to S134. In S134, the idle flag is turned ON. In S135, a control command indicating that the non-game is continued for a certain time is set. In S136, the control command set in S135 is transmitted to the sub-control unit 400, and the process ends. The sub-control unit 400 that has received the control command displays a so-called demo screen on the LCD 10. In S137, the idle flag is turned off. The process ends as described above.

<Game state control processing>
Next, the game state update process of S111 will be described. FIG. 26 is a flowchart showing the gaming state control process of S111. In S141, it is determined whether or not the current game is a game in the BB game. If applicable, the process proceeds to S142, and if not, the process proceeds to S144. In S142, the profit counter is updated. The profit counter is a software counter set on the RAM 313, and is a counter that counts the profit obtained by the player during the BB game in order to determine the end condition of the BB game. The profit counter is reset at the start of the BB game, and for example, the net increase in the number of medals during the BB game (cumulative value of the difference between the payout number and the inserted number) may be counted. Also, the profit counter regards that a corresponding medal has been paid out in the BB game, regardless of whether or not a winning combination is won internally (hereinafter referred to as a deemed payout number). Also, it may be a cumulative value of the difference between the number of payouts and the number of inserts only during the BB game.

  In S143, it is determined whether or not the value of the profit counter exceeds a predetermined value. When it corresponds, it progresses to S152 and sets a normal game as a gaming state. As a result, the BB game ends and the next game is changed to the normal game. If not, the process proceeds to S144. In S144, it is determined whether or not the RB is won in this game. If applicable, the process proceeds to S149, and if not, the process proceeds to S145. In S145, it is determined whether or not SRB has been won in this game. If applicable, the process proceeds to S149, and if not, the process proceeds to S146. In S146, it is determined whether or not BB is won in this game. If applicable, the process proceeds to S150, and if not, the process proceeds to S147.

  In S147, it is determined whether or not the current gaming state is an RB game. If applicable, the process proceeds to S151. Otherwise, the process proceeds to S148. In S148, it is determined whether or not the current gaming state is an SRB game. If applicable, the process proceeds to S151, and if not applicable, the process ends. In S149, an RB / SRB winning process is performed. Here, an RB game or an SRB game is set as the gaming state. In addition, 12 times and 8 times are set as initial values of the software counter that manages the number of games played in the RB game or the SRB game and the software counter that manages the number of winnings of the bonus item, respectively. In S150, a process for winning a BB is performed. Here, a BB game (BB general game) is set as the gaming state. In S151, processing during the RB / SRB game is performed. Here, one software counter for managing the number of games of the RB game or the SRB game is subtracted. When a prize is won in the game this time, the count value of the software counter that manages the number of winnings of the prize is subtracted by one. Further, when the count value of any one of these software counters becomes 0, a normal game is set as the gaming state during the RB game, and a BB general game is set during the SRB game. As a result, the next game becomes a normal game or a BB general game. The process ends as described above.

<Processing of sub-control unit>
Next, processing of the sub control unit 400 will be described. FIG. 27A is a flowchart of interrupt processing executed by the CPU 410 of the sub-control unit 400, and FIG. 27B is a flowchart of main processing executed by the CPU 410 of the sub-control unit 400. First, interrupt processing will be described with reference to FIG. The CPU 410 performs the process of FIG. In S201, it is determined whether a command from the main control unit 300 has been received. If applicable, the process proceeds to S202, and if not applicable, the process ends. In S202, control commands received from the main control unit 300 are sequentially stored without overwriting a predetermined area (referred to as a command storage area) of the RAM 413.

  Next, the main process will be described with reference to FIG. In S211, it is determined whether or not at least one control command is stored in the command storage area. If applicable, the process proceeds to S212, and if not, the process returns to S211. In S212, one control command is acquired from the command storage area, and its content is determined. The acquired control command is deleted from the command storage area. In S213, the effect data described with reference to FIG. 21 is acquired according to the determination result in S212. In S214, it is determined whether or not the effect data acquired in S213 includes data to be output to the driver of each effect device of the sub-control unit 400. If applicable, the process proceeds to S215, and if not, the process proceeds to S216. In S215, data is set in the driver of the rendering device of the sub control unit 400. The production device executes the production according to the data by setting the data.

  In S216, it is determined whether or not the effect data acquired in S213 includes a control command to be transmitted to the effect unit control unit 500. If applicable, the process proceeds to S217, and if not, the process returns to S211. In S217, a control command is transmitted to the rendering unit control unit 500, and the process returns to S211.

<Processing of production unit control unit>
Next, processing of the rendering unit control unit 500 will be described. FIG. 28A is a flowchart of interrupt processing executed by the CPU 510 of the effect unit control unit 500, and FIG. 28B is a flowchart of main processing executed by the CPU 510 of the effect unit control unit 500. First, interrupt processing will be described with reference to FIG. The CPU 510 performs the process of FIG. In S301, it is determined whether a command from the sub-control unit 400 has been received. If applicable, the process proceeds to S302, and if not applicable, the process ends. In S302, control commands received from the sub-control unit 400 are sequentially stored without overwriting a predetermined area (referred to as a command storage area) of the RAM 513.

  Next, the main process will be described with reference to FIG. In S311, it is determined whether or not at least one control command is stored in the command storage area of the RAM 513. If applicable, the process proceeds to S312; otherwise, the process returns to S311. In S312, one control command is acquired from the command storage area of the RAM 513, and the content is determined. The acquired control command is deleted from the command storage area. In S313, effect data is acquired according to the determination result in S312. In S314, it is determined whether or not the effect data acquired in S313 includes data to be output to the driver of each effect device of the effect unit control unit 500 (the driver of each device of effect unit A). If applicable, the process proceeds to S315, and if not, the process returns to S311. In S315, data is set in the driver of each device of the rendering unit A, and the process returns to S311. The production unit A executes the production according to the data by setting the data.

<Example of switching between 2D image and 3D image>
As described above, according to the rendering unit A of the present embodiment, a two-dimensional image can be provided to the player when the LCD 10 is in the first position, and a three-dimensional image can be provided to the player when the LCD 10 is in the second position. The two-dimensional image has an advantage that the display content is easy to understand, and the three-dimensional image has an advantage that the effect of enhancing the fun of the game is high. Here, an example of switching between the two will be described.

-Switching according to the setting of the gaming state The LCD 10 can be moved from the first position to the second position according to the setting result (S111) of the gaming state. For example, during a normal game, the LCD 10 is moved to a first position to display a two-dimensional image, while during a BB game or an RB game, the LCD 10 is moved to a second position to display a three-dimensional image. By doing so, it is possible to produce an effect that further enhances the interest of the player. In the present embodiment, the game state is roughly divided into a normal game, a BB game, and an RB game. In addition to this, when so-called AT (assist time), CT (challenge time), lip series, etc. are adopted. The two-dimensional image and the three-dimensional image can be switched in accordance with the setting of the game state of the player, and in particular, when these are set, it is possible to produce an effect that excites the player's interest by displaying the three-dimensional image. . The AT is, for example, a request for pressing order of the stop buttons 131a to 131c for reel stop control, and notifies the pressing order within the AT period. In addition, CT means, for example, that at least one of the reels 110 to 112 is stopped in principle when a player operates the stop buttons 131a to 131c and no sliding piece control is performed within a CT period. It is. For example, a lip series is a prize that has a higher probability of being replayed in a lip series period than in other cases.

Switching according to the setting of the effect type The LCD 10 can be moved from the first position to the second position according to the setting of the effect type. As described above, in this embodiment, the type of effect is set by the effect group, and the LCD 10 moves from the first position to the second position according to the setting.

Switching according to the player's profit The LCD 10 can be moved from the first position to the second position according to the profit given to the player as a result of the game. For example, the LCD 10 is moved to the first position to display a two-dimensional image until the count value of the above-described profit counter (such as S142) exceeds a predetermined value (smaller than the predetermined value of the BB game end condition). If it exceeds, the LCD 10 is moved to the second position to display a three-dimensional image. For example, when the predetermined value of the end condition of the BB game is 400, a three-dimensional image is displayed when the count value of the profit counter exceeds 200. By doing so, it is possible to produce a gorgeous presentation in accordance with an increase in the player's profits, and it is possible to produce a stage that further enhances the player's interest.

-Switching according to whether or not internal winning is in progress As described above, in this embodiment, the flag carryover of the internal winning results of BB and RB is performed. Therefore, the LCD 10 can be positioned at the second position while BB and RB are internally won. The display of the three-dimensional image on the LCD 10 becomes a notification of the internal winning of BB and RB, and can raise the player's expectation. Note that the LCD 10 may be positioned at the second position while the BB and RB are internally won only when the lottery is selected. In addition, as an effect of the gaze, the LCD 10 may be positioned at the second position even though BB and RB are not internally won.

Switching at Demo Display When the slot machine 100 is not playing a game, the LCD 10 can be moved to the second position, and the LCD 10 can display a non-game playing image (a so-called demo screen). For example, when the sub-control unit 400 receives the control command in S136 of FIG. 25, a demonstration screen using a three-dimensional image is displayed. When there are no players in the slot machine 100, it is possible to attract the surrounding players in the hall, and the operating rate of the slot machine 100 in the hall can be raised.

Switching at the time of error When it is determined that an error has occurred in the slot machine 100, the LCD 10 can be moved to the second position, and information on the error can be displayed on the LCD 10. For example, it is determined whether or not an error has occurred in S125 of FIG. 24. If it is determined that an error has occurred, a control command indicating that fact is transmitted to the sub-control unit 400, but this is received. The sub-control unit 400 moves the LCD 10 to the second position and causes the LCD 10 to display information regarding the error. The error notification of the slot machine 100 is discouraging for the player, but it is possible to attract the player's interest by notifying the error with a three-dimensional image.

-Switching by lottery In accordance with a control command from the main control unit 300, the sub-control unit 400 performs lottery and the LCD 10 is moved to the first position (two-dimensional mode), and the LCD 10 is switched to the second mode. Switching between the mode (three-dimensional code) of the three-dimensional image moved to the position can be performed. FIG. 29A is a flowchart showing a switching process between the two-dimensional mode and the three-dimensional mode by lottery, and is executed by the CPU 410 of the sub-control unit 400.

  In S401, it is determined whether or not the control command from the main control unit 300 is a mode switching command. The mode switching command can be, for example, a control command indicating that a specific type of reel stop control data has been selected. If applicable, the process proceeds to S402, and if not applicable, the process ends. In S402, a lottery is performed as to whether to set the two-dimensional mode or the three-dimensional mode. In S403, it is determined whether or not a mode different from the current mode is won. If applicable, the process proceeds to S404, and if not, the process ends. For example, if it is the current two-dimensional mode and the lottery result in S402 is the three-dimensional mode, the process proceeds to S404, and if it is the two-dimensional mode, the process is terminated. In S404, the mode of the lottery result in S402 (the other mode of the current mode out of the two-dimensional mode and the three-dimensional mode) is set, and the process ends.

Switching according to the number of games According to a control command from the main control unit 300, the sub-control unit 400 counts the number of games and moves the LCD 10 to the first position (two-dimensional mode), and the LCD 10 Switching between the mode (three-dimensional code) of the three-dimensional image moved to the second position can be performed. FIG. 29B is a flowchart showing switching processing between the two-dimensional mode and the three-dimensional mode depending on the number of games, and is executed by the CPU 410 of the sub-control unit 400.

  In S411, it is determined whether or not the control command from the main control unit 300 is a mode switching command. The mode switching command can be, for example, a control command indicating that a specific type of reel stop control data has been selected. If applicable, the process proceeds to S412. If not applicable (in the case of a control command indicating that other reel stop control data has been selected), the process proceeds to S416. In S412, a lottery for setting the three-dimensional mode is performed. In S413, it is determined whether or not the three-dimensional mode is won in the lottery of S412. If applicable, the process proceeds to S414, and if not, the process proceeds to S416. In S415, the number of games for continuing the three-dimensional mode is set. The number of games is managed by a software counter (referred to as a three-dimensional mode counter) set in a predetermined area on the RAM 413, and an initial value of the count value is set in S415.

  In S416, it is determined whether or not the current mode is a three-dimensional mode. If applicable, the process proceeds to S417, and if not applicable, the process ends. In S417, one count value of the three-dimensional mode counter is subtracted. In S418, it is determined whether or not the count value of the three-dimensional mode counter is zero. If applicable, the process proceeds to S419, and if not, the process ends. In S419, a two-dimensional code is set and the process ends.

-Switching by player selection The LCD 10 can be moved to a position selected by the player. In this case, the selection button 137 is caused to function as a selection unit for the player to select the first position and the second position of the LCD 10. A two-dimensional image mode (two-dimensional mode) in which the LCD 10 is moved to the first position and a three-dimensional image mode (three-dimensional mode) in which the LCD 10 is moved to the second position according to the player's preference. Can be provided. FIG. 30 is a flowchart showing a switching process between the two-dimensional mode and the three-dimensional mode according to the player's selection, and is executed by the CPU 410 of the sub-control unit 400 by an interruption process.

  In S501, it is determined whether or not a selection operation in the two-dimensional mode has been accepted by the selection button 137. For example, an operation on the left selection button 137 can be a two-dimensional mode selection operation. If applicable, the process proceeds to S502, and if not, the process proceeds to S503. In S502, the two-dimensional mode is set, and then the process ends. In step S <b> 503, it is determined whether a selection operation in the three-dimensional mode has been accepted by the selection button 137. For example, the operation on the selection button 137 on the right side can be a selection operation in the three-dimensional mode. If applicable, the process proceeds to S504, and if not, the process ends. In S504, the three-dimensional mode is set, and then the process ends.

<Example of opening and closing the door 51>
The door 51 is basically fully closed when the LCD 10 is moved between the first position and the second position, and is fully opened after the movement is completed. By doing so, the impact of switching between the two-dimensional image and the three-dimensional image can be given to the player. However, the present invention is not limited to this, and the door 51 can be opened and closed by various methods.

  For example, during a plurality of games, the door 51 is positioned at the shielding position to be fully closed, and then the door 51 is positioned at the non-shielding position to be fully opened. In this example, for example, after a game in which BB or RB is internally won, during a plurality of games (in this time, it is desirable to perform reel control so as not to win BB and RB), the door 51 is fully closed. When the state is set to the full open state, the LCD 10 notifies that the internal winning has been made. The notification may be a notification using a two-dimensional image or a notification using a three-dimensional image, but by using the notification using a three-dimensional image, the excitement of the player can be enhanced. While the door 51 is fully closed, the player can expect an internal winning of BB or RB. In this case, the door 51 can be fully closed during a plurality of games even though the BB or RB is not internally won as an effect of the gaze. Then, when the two-dimensional image is displayed when the door 51 is fully opened, it is indicated that the display is lost, and when the BB or RB is internally won, the three-dimensional image can be displayed.

  Further, for example, the selection button 137 is used as a selection means for the player to select the shielding position and shielding position of the door 51, and the player is fully opened by moving the door 51 to the position selected by the player. And fully closed may be selected. For example, when the player presses the selection button 137 when the door 51 is fully closed, the door 51 is fully opened, and the internal winning result of BB or RB is displayed in two dimensions or three dimensions, or a loss is displayed. Doing so can increase the excitement of the player.

<Application to pachinko machines>
