In the following embodiments, the effect control means according to the present invention is mainly realized by the sub control board 21 and the image control board 22. The first state, the second state, the third state, and the fourth state according to the present invention correspond to a fully open state, a fully closed state, a medium size display state, and an X-shaped display state, respectively. The first shielding portion according to the present invention corresponds to the first shielding plate 50a, the retracted state of the first shielding portion is in the state where the first shielding plate is in the retracted position, and the advanced state of the first shielding portion is the first. This corresponds to a state in which one shielding plate is in the advanced position. Moreover, the 2nd shielding part which concerns on this invention is corresponded to the 2nd shielding board 50b and the 3rd shielding board 50c. The trapezoidal shielding plate and the triangular shielding plate according to the present invention correspond to the second shielding plate 50b and the third shielding plate 50c, respectively.

In this embodiment, the present invention is applied to a slot machine.
As shown in FIG. 1, the housing 2 of the slot machine 1 is covered with a front door 3 from the front. A reel viewing window 4 for visually recognizing three reels 9 disposed inside the housing 2 is provided at the center of the front door 3. On the front side of the front door 3, below the reel viewing window 4, operation switches such as bet switches 5 a and 5 b, a start switch 6, a stop switch 7, and a settlement switch 8 used for game operations, and an effect used for production A button unit 13 is provided. Further, a display screen viewing window 15 for viewing the rectangular display screen 14 of the image display 10 is disposed above the reel viewing window 4. The display screen viewing window 15 is a rectangular opening having the same shape and size as the display screen 14 of the image display 10, and is covered with a transparent resin panel 16.

  The image display 10 is a liquid crystal display. As will be described later, various effect images are displayed on the horizontally-long rectangular display screen 14 of the image display 10. As shown in FIGS. 1 and 2, the screen shielding device 17 according to the present invention is disposed on the back side of the display screen viewing window 15 of the front door 3, and the image display 10 is further back of the screen shielding device 17. Arranged on the side. The screen shielding device 17 has an opening 39 having the same shape and the same size as the rectangular display screen 14, and a fully open state in which a later-described shielding member is retracted around the opening 39 to open the opening 39. It can be converted into a fully closed state in which the opening 39 is closed by the shielding member. The image display 10 is arranged so that the display screen 14 is overlapped with the opening 39 in the front-rear direction, and the entire display screen 14 can be viewed from the display screen viewing window 15 when the screen shielding device 17 is fully opened. Thus, when the screen shielding device 17 is fully closed, the entire display screen 14 is configured to be difficult to visually recognize.

Hereinafter, the screen shielding device 17 will be described in detail.
As described above, the screen shielding device 17 has a rectangular frame shape with the opening 39 having the same shape and the same size as the display screen 14 of the image display 10. As shown in FIGS. By opening and closing the part 39 with the shielding members 41a to 41d, the entire display screen 14 becomes a non-shielding region 71 that is not shielded by the shielding members 41a to 41d, and a fully closed state in which the entire display screen 14 is shielded. It can be converted into a state.

  As shown in FIG. 5, the screen shielding device 17 is arranged on each of the upper, lower, left, and right sides of the display screen 14, and the four sets of shielding members 41 a to 41 a that move forward and backward from the periphery of the display screen 14 toward the front side of the display screen 14. 41d. These shielding members 41a to 41d are configured to individually shield four triangular regions 70a to 70d formed by dividing the display screen 14 vertically and horizontally by two diagonal lines D1 and D2. Specifically, the shielding member 41 a that advances from the left side of the display screen 14 is configured to shield the triangular area 70 a on the left side of the display screen 14. Similarly, the shielding member 41b that advances from the right side shields the right triangular region 70b, the shielding member 41c that advances from the upper side shields the upper triangular region 70c, and the shielding member 41d that advances from the lower side shields the lower triangular region 70d. Configured to be possible. As will be described later, each of the shielding members 41a to 41d is a telescopic type composed of three shielding plates 50a to 50c.

  As shown in FIG. 6, the screen shielding device 17 includes four sets of shielding units 40 a to 40 d disposed on the top, bottom, left, and right of the display screen 14 of the image display 10, and each shielding unit 40 a to 40 d from the back side. And a base plate 43 to be supported. The shielding members 41a to 41d are disposed one by one in each shielding unit 40a to 40d, and are driven by a driving means 49 disposed in each shielding unit 40a to 40d. Further, as shown in FIG. 4, a shielding control board 45 that controls the driving means 49 of each shielding unit 40 a to 40 d is disposed at the lower back of the base plate 43.

  The four sets of shielding units 40a to 40d are different in the direction in which the shielding members 41a to 41d are advanced and retracted, but the basic configurations of the shielding members 41a to 41d and the driving means 49 are the same. Therefore, in the following, the structure of the left shielding unit 40a disposed on the left side of the display screen 14 will be described, and the basic configuration of the shielding members 41a to 41d and the driving means 49 of each shielding unit 40a to 40d will be described. explain.

  7 to 9, the left shielding unit 40a includes a shielding member 41a, a support member 47 disposed on the left side of the display screen 14 and supporting the shielding member 41a, and a driving unit that drives the shielding member 41a. 49 and a cover member 48 that covers the driving means 49.

  The shielding member 41a is configured to shield the triangular area 70a on the left side of the display screen 14. The shielding member 41a is a telescopic type composed of three shielding plates 50a to 50c. The three shielding plates 50a to 50c are a first shielding plate 50a having an isosceles trapezoidal shape, a second shielding plate 50b having an isosceles trapezoidal shape smaller than the first shielding plate 50a, and an isosceles triangular shape. And three shielding plates 50c. Here, each of the shielding plates 50a to 50c has a shape corresponding to a triangular portion obtained by dividing the triangular region 70a into three equal parts in the forward and backward directions of the shielding member 41a and two large and small isosceles trapezoidal portions. The two shielding plates 50a to 50c are continuous in the advancing direction of the shielding member 41a to form an isosceles triangle shape that can shield the triangular region 70a on the left side of the display screen 14.

  The shielding plates 50a to 50c will be described in detail. The isosceles trapezoidal first shielding plate 50a is slidably disposed along the left and right guide rails 51 formed on the support member 47, and has a display screen. 14 is movable between a left retracted position retracted from the front side of 14 and a right advanced position advanced to the front side of the display screen 14. When the first shielding plate 50a is in the advanced position, the isosceles trapezoidal portion of the triangular area 70a near the edge of the display screen 14 is shielded by the first shielding plate 50a.

  The isosceles trapezoidal second shielding plate 50b is arranged to be slidable to the left and right with respect to the first shielding plate 50a, and has a left retracted position hidden behind the first shielding plate 50a and a front view. In FIG. 1, the first shielding plate 50a and a rightward advance position forming one isosceles trapezoidal shape are movable.

  The isosceles triangle-shaped third shielding plate 50c is slidably disposed to the left and right with respect to the second shielding plate 50b, and is retracted to the left and hidden behind the second shielding plate 50b. In FIG. 5, the second shielding plate 50b can be moved between an advancing position forming one isosceles triangle.

  In this configuration, the shielding member 41a is as shown in FIGS. 6 (a), 7 (a), and 8 (a) in the fully retracted state in which all the three shielding plates 50a to 50c are in the retracted position. The three shielding plates 50a to 50c are overlapped and retracted from the front side of the display screen 14. Further, as shown in FIGS. 6 (b), 7 (b), and 8 (b), the shielding member 41a is in the fully advanced state where all the three shielding plates 50a to 50c are advanced positions. The two trapezoidal portions and the one triangular portion that are shielded by ˜50c are connected to the left and right to form a triangle that is substantially the same shape as the left triangular region 70a, thereby shielding the entire triangular region 70a.

  The drive unit 49 converts the shielding member 41a into the fully retracted state and the fully advanced state by moving the three shielding plates 50a to 50c to the retracted position and the advanced position. Here, the driving means 49 does not move the three shielding plates 50a to 50c at the same time, but moves them one by one from the retracted position to the advanced position or from the advanced position to the retracted position. And it is comprised so that the shielding plates 50a-50c can be moved in two ways. Specifically, in this embodiment, the first shielding plate 50a is the first shielding portion, the second shielding plate 50b and the third shielding plate 50c are the second shielding portion, and the driving means 49 is the shielding member 41a. Is converted from the fully retracted state to the fully advanced state, the first shielding plate 50a is first moved to the advanced position as in (a) → (d) → (e) → (f) in FIG. When the second shielding plate 50b and the third shielding plate 50c (second shielding portion) are first moved to the advanced position as in (a) → (b) → (c) → (f) in FIG. It is possible to convert in two ways. On the other hand, when the shielding member 41a is converted from the fully advanced state to the fully retracted state, the first shielding plate 50a is first used as shown in (f) → (c) → (b) → (a) in FIG. When moving to the retracted position and when moving the second shielding plate 50b and the third shielding plate 50c first to the retracted position as in (f) → (e) → (d) → (a) in FIG. It is possible to convert in two ways. The drive means 49 is configured to move the second shielding plate 50b and the third shielding plate 50c to the advanced position in the order of the second shielding plate 50b → the third shielding plate 50c when converting the second shielding plate 50b and the third shielding plate 50c to the advanced position. . On the other hand, when the second shielding portion is converted to the retracted state, the second shielding portion is moved to the retracted position in the order of the third shielding plate 50c → the second shielding plate 50b.

  Thus, the drive means 49 is the order which makes the 1st shielding board 50a (1st shielding part) the advance position first, and the 2nd shielding board 50b and the 3rd shielding board 50c (2nd shielding part) first. The shielding plates 50a to 50c are configured to be convertible between the fully retracted state and the fully advanced state in two orders, the order of setting the advanced position. For this reason, the drive means 49 stops the movement of the shielding plates 50a to 50c during the conversion between the fully retracted state and the fully advanced state, so that only the first shielding plate 50a is in the advanced position (see FIG. 10 (d)), and the shielding member 41a can be converted into two transition states of a triangular advancing state (FIG. 10 (c)) in which only the second shielding plate 50b and the third shielding plate 50c are advanced positions. . Further, as described above, the driving unit 49 does not move the second shielding plate 50b and the third shielding plate 50c at the same time, the second shielding plate 50b is in the advanced position, and the third shielding plate 50c is in the retracted position. It can be converted to an intermediate state. For this reason, the drive means 49 is in the above-mentioned two orders, and only the second shielding plate 50b is obtained by converting the second shielding plate 50b and the third shielding plate 50c (second shielding portion) to the intermediate state. A small trapezoidal advance state (see FIG. 10 (b)) that becomes the advance position and a large trapezoid advance state (see FIG. 10 (e)) in which two of the first shielding plate 50a and the second shielding plate 50b become advance positions. The shielding member 41a can be converted into two transition states.

  The drive means 49 will be described in detail. As shown in FIGS. 11 and 12, the drive means 49 transmits the driving force of the stepping motor 54, the flat groove cam 55, and the stepping motor 54 as a drive source to the flat groove cam 55. A gear 56, two cam arms 57a and 57b tilting in accordance with the rotation of the flat groove cam 55, connecting arms 58a and 58b for transmitting the movements of the cam arms 57a and 57b to the shielding plates 50a and 50c, and a second And a tension arm 61 that urges the shielding plate 50b to the advanced position.

  The flat groove cam 55 is a gear-like member having cam grooves 59 a and 59 b formed on both sides, and is engaged with a gear 56 fixed to the rotation shaft of the stepping motor 54 and driven by the stepping motor 54. The stepping motor 54 rotates at an angle corresponding to a signal from the shielding control board 45. Around the flat groove cam 55, three angle sensors 60 for detecting the rotation angle of the flat groove cam 55 are arranged. Based on the detection signal of the angle sensor 60, the shielding control board 45 is fixed to the flat groove cam. The rotation angle of 55 can be controlled.

  Of the two cam arms 57a and 57b, the first cam arm 57a has one end engaged with the cam groove 59a on the surface of the flat groove cam 55, and the other end connected to the first cam arm 57a via the first connecting arm 58a. The first shielding plate 50a is connected to the shielding plate 50a and moved in the left-right direction as the flat groove cam 55 rotates.

  Of the two cam arms 57a and 57b, the second cam arm 57b has one end engaged with the cam groove 59b on the back surface of the flat groove cam 55 and the other end connected to the third via the second connecting arm 58b. The third shielding plate 50c is connected to the shielding plate 50c and moved in the left-right direction as the planar groove cam 55 rotates.

  As shown in FIG. 13A, the driving means 49 is configured such that when the flat groove cam 55 is at a predetermined reference angle, the two cam arms 57a and 57b retract all three shielding plates 50a to 50c. And the shielding member 41a is fully retracted. In addition, when the driving means 49 rotates the flat groove cam 55 by 90 ° from the reference angle, as shown in FIG. 13B, the two cam arms 57a and 57b have all three shielding plates 50a. ˜50c is moved to the advanced position so that the shielding member 41a is fully advanced.

  Here, when the planar groove cam 55 is rotated from the reference position by making the cam grooves 59a and 59b on the front and back surfaces of the planar groove cam 55 asymmetrical, the driving means 49 has a shielding plate 50a depending on the rotation direction. The moving order of ˜50c is different. That is, when the planar groove cam 55 is rotated 90 ° counterclockwise in the state shown in FIG. 13A, the shielding plates 50a to 50c are changed to (a) → (b) → (c) in FIG. → When moving to the advance position in the order of (f) and rotating the planar groove cam 55 by 90 ° in the clockwise direction, the shielding plates 50a to 50c become (a) → (d) → (e) in FIG. → Move to the advance position in the order of (f).

  More specifically, when the flat groove cam 55 is rotated 30 ° counterclockwise from the reference position (all retracted state), only the second cam arm 57b is tilted as shown in FIG. Then, the third shielding plate 50c is moved to the right by one third of the movable range. At this time, when the second shielding plate 50b urged in the advance direction moves to the right with the third shielding plate 50c, the shielding member 41a has only the second shielding plate 50b at the advance position. Enters a small trapezoidal state.

  When the planar grooved cam 55 is further rotated 30 ° counterclockwise from the small trapezoidal advance state shown in FIG. 10B, only the second cam arm 57b is tilted and linked as shown in FIG. 10C. The third shielding plate 50c is further moved to the right by one third of the movable range via the arm 58b. At this time, since the second shielding plate 50b has already reached the advanced position, only the third shielding plate 50c moves rightward to the advanced position, whereby the shielding member 41a is connected to the second shielding plate 50b and the third shielding plate 41b. A triangular advancing state where the shielding plate 50c is the advancing position is achieved.

  When the planar groove cam 55 is further rotated 30 ° counterclockwise from the triangular advancing state shown in FIG. 10C, the two cam arms 57a and 57b are tilted as shown in FIG. The first shielding plate 50a and the third shielding plate 50c are cooperatively moved to the right via the two connecting arms 58a and 58b. At this time, since the second shielding plate 50b biased in the advance direction moves to the right together with the other shielding plates 50a and 50c, at this stage, the three shielding plates 50a to 50c are integrated into the right. When the first shielding plate 50a that has been moved to the last position and moved to the advanced position moves to the advanced position, the shielding member 41a is fully advanced.

  On the other hand, when the flat groove cam 55 is rotated 30 ° clockwise from the reference position, the two cam arms 57a and 57b are tilted as shown in FIG. 10D, and the two connecting arms 58a and 58b are moved. The first shielding plate 50a and the third shielding plate 50c are cooperatively moved to the right. The second shielding plate 50b also moves to the right together with the other shielding plates 50a and 50c by the urging force. Thus, at this stage, since the three shielding plates 50a to 50c at the retracted position move together as a unit, only the first shielding plate 50a moves from the retracted position to the advanced position, thereby shielding the shielding. The member 41a is in a middle trapezoidal advance state where only the first shielding plate 50a is the advance position.

  When the flat groove cam 55 is further rotated counterclockwise by 30 ° from the state of advancement of the middle trapezoid shown in FIG. 10D, only the second cam arm 57b is tilted and linked as shown in FIG. The third shielding plate 50c is further moved to the right by one third of the movable range via the arm 58b. At this time, the second shielding plate 50b urged in the advance direction moves to the right with the third shielding plate 50c, so that the shielding member 41a has the first shielding plate 50a and the second shielding plate 50b. Becomes a large trapezoidal advance state.

  When the planar groove cam 55 is further rotated by 30 ° counterclockwise from the large trapezoidal advance state shown in FIG. 10 (e), only the second cam arm 57b is tilted and linked as shown in FIG. 10 (f). The third shielding plate 50c is moved rightward to the limit of the movable range via the arm 58b. At this time, since the second shielding plate 50b has already reached the advanced position, at this stage, only the third shielding plate 50c moves to the right, and the third shielding plate 50c that has been in the retracted position until the end has advanced. By moving to the position, the shielding member 41a is fully closed.

  Thus, when the driving means 49 rotates the planar groove cam 55 counterclockwise from the fully retracted state, the driving means 49 enters the fully advanced state via the two transition states of the small trapezoid advanced state and the triangular advanced state, When the cam 55 is rotated clockwise from the fully retracted state, the cam 55 is configured to be in the fully advanced state via two transition states of a middle trapezoidal advanced state and a large trapezoidal advanced state. Note that the conversion from the fully retracted state to the fully advanced state is reversible, and when the planar groove cam 55 is rotated 90 ° clockwise from the fully advanced state, the entire state passes through the triangular advanced state and the small trapezoid advanced state. When in the retracted state and rotated 90 ° counterclockwise, the entire retracted state is reached via the large trapezoidal advance state and the middle trapezoidal advance state.

  Thus, the shielding member 41a is configured to be convertible by the driving means 49 into four transition states in which some of the shielding plates 50a to 50c are located at the advanced positions in addition to the fully opened state and the fully closed state. The driving means 49 rotates the stepping motor 54 at a step angle smaller than 30 °, so that the shielding plates 50a to 50c are positioned between the advanced position and the retracted position in addition to the four transition states. It is possible to convert the shielding member 41a.

  Although the left shielding unit 40a has been described in detail above, the other shielding units 40b to 40d have basically the same configuration as the left shielding unit 40a. That is, in all the shielding units 40a to 40d of the screen shielding device 17, the shielding members 41a to 41d are composed of three shielding plates 50a to 50c. The shielding members 41a to 41d can be converted to the transition state. The right shielding unit 40b disposed on the right side of the display screen 14 includes a shielding member 41b having the same shape as the left shielding unit 40a. On the other hand, the upper shielding unit 40c and the lower shielding unit 40d disposed above and below the display screen 14 have the shielding plates 50a to 50c wider than the left shielding unit 40a in accordance with the shapes of the triangular areas 70c and 70d to be shielded. Shielding members 41c and 41d are provided.

  The shielding control board 45 of the screen shielding device 17 is connected to the stepping motor 54 and the angle sensor 60 of each shielding unit 40a to 40d, and when receiving an input signal from the sub-control board 21, as will be described later, the stepping motor. 54 is driven to rotate the flat groove cam 55 to a required angle, thereby selectively converting the shielding members 41a to 41d of the shielding units 40a to 40d into the fully advanced state, the fully retracted state, and the four transition states. It is configured to be able to. The state conversion of the shielding members 41a to 41d by the stepping motor 54 is configured to be completed within 1 second.

Specifically, the shielding control board 45 can convert the screen shielding device 17 into the following states (1) to (6) by controlling the four shielding members 41a to 41d to the same state. ing.
(1) Fully open state As shown to Fig.14 (a), it is the state which all the shielding members 41a-41d will be in a fully retracted state. In such a fully open state, the display screen 14 is not shielded by the shielding members 41 a to 41 d, and the entire display screen 14 becomes the non-shielding region 71.
(2) Fully closed state As shown in FIG.14 (f), it is the state which all the shielding members 41a-41d will be in the fully advanced state. In the fully closed state, the four triangular areas 70a to 70d of the display screen 14 are shielded by the shielding members 41a to 41d, and the display screen 14 is completely shielded.
(3) Medium size display state As shown in FIG.14 (b), it is the state which all the shielding members 41a-41d will be in the middle trapezoid advance state. In the medium size display state, the first shielding plate 50a of the four sets of shielding members 41a to 41d shields the outer peripheral portion of the display screen 14 in a rectangular frame shape, so that the non-shielding region 71 is the center of the display screen 14. As a reference, the vertical and horizontal dimensions of the display screen 14 are reduced to 2/3 times a rectangular shape.
(4) Small size display state As shown in FIG.14 (c), it is the state which all the shielding members 41a-41d will be in the large trapezoid advance state. In such a small size display state, the first shielding plate 50a and the second shielding plate 50b of the four sets of shielding members 41a to 41d shield the outer peripheral portion of the display screen 14 in a rectangular frame shape, whereby the non-shielding region 71 is formed. The rectangular shape is obtained by reducing the vertical and horizontal dimensions of the display screen 14 to 1/3 with respect to the center of the display screen 14.
(5) Radial display state As shown in FIG.14 (d), it is the state which all the shielding members 41a-41d will be in the small trapezoid advance state. In such a radial display state, the non-shielding region 71 has a shape that spreads radially toward the four corners of the display screen 14.
(6) X-shaped display state As shown in FIG.14 (e), it is the state which all the shielding members 41a-41d became the triangle advance state. In such an X-shaped display state, the display screen 14 is shielded in a triangular shape protruding in the center direction of the display screen 14 from the center of the top, bottom, left, and right edges of the display screen 14, so that the non-shielding region 71 is The X-shape spreads toward the four corners of the display screen 14 with the center of the display screen 14 as an intersection.

Further, the shielding control board 45 can convert the screen shielding device 17 to the diagonal display state by converting two of the four shielding members 41a to 41d to the fully retracted state and the remaining two to the fully advanced state. ing. In the diagonal display state, one of the two diagonal division regions 72 a to 72 d obtained by dividing the display screen 14 by any one of the diagonal lines D <b> 1 and D <b> 2 is shielded, and the other is the non-shielding region 71. The diagonal display states include the following four types (7) to (10) depending on the diagonal lines D1 and D2 that divide the display screen 14 and the diagonal division areas 72a to 72d that become the non-shielding area 71.

The members 41b and 41d are in a fully retracted state. In such a second diagonal display state, the upper left diagonal division area 72a of the display screen 14 divided by the diagonal line D1 is shielded, and the lower right diagonal division area 72b of the display screen 14 becomes the non-shielding area 71.
(9) Third diagonal display state As shown in FIG. 15C, the shielding members 41a and 41d of the left shielding unit 40a and the lower shielding unit 40d are fully retracted, and the right shielding unit 40b and the upper shielding unit 40c are shielded. The members 41b and 41c are in a fully advanced state. In the third diagonal display state, the diagonal division area 72c in the lower left part of the display screen 14 divided by the diagonal line D2 becomes the non-shielding area 71, and the diagonal division area 72d in the upper right part of the display screen 14 is shielded.
(10) Fourth Diagonal Display State As shown in FIG. 15D, the shielding members 41a and 41d of the left shielding unit 40a and the lower shielding unit 40d are fully advanced, and the right shielding unit 40b and the upper shielding unit 40c are shielded. The members 41b and 41c are in a fully retracted state. In such a fourth diagonal display state, the diagonal division area 72c in the lower left portion of the display screen 14 divided by the diagonal line D2 is shielded, and the diagonal division area 72d in the upper right portion of the display screen 14 becomes the non-shielding area 71.

The shielding control board 45 converts the two shielding members 41a to 41d into a large trapezoidal advance state and the other two into a fully retracted state, whereby the screen shielding device 17 is displayed in the depth display state. It can be converted to. In the depth display state, the non-shielding region 71 has a shape that is reduced in width toward the center of the display screen 14 from two edges where the shielding members 41 a to 41 d do not advance. There are the following two types (11) and (12) of the depth display state depending on the shielding members 41a to 41d converted into the large trapezoidal advance state.
(11) First Depth Display State As shown in FIG. 16A, the left and right shielding members 41a and 41b are in a fully retracted state, and the upper and lower shielding members 41c and 41d are in a large trapezoidal advance state. In the first depth display state, the upper and lower shielding members 41c and 41d shield the display screen 14 in an isosceles trapezoidal shape with the upper and lower edges of the display screen 14 as the bottom sides, respectively. As a result, the non-shielding area 71 of the display screen 14 has a pair of left and right trapezoids that form an isosceles trapezoidal shape with the left and right edges of the display screen 14 being the bottom sides and reducing the width toward the center of the display screen 14, respectively. The non-shielding areas 74a and 74b and the rectangular non-shielding area 73 formed in the center of the display screen 14 and formed between the trapezoidal non-shielding areas 74a and 74b. Here, the rectangular non-shielding region 73 has a similar shape in which the vertical and horizontal dimensions are reduced to 1/3 times with respect to the center of the display screen 14, and the trapezoidal non-shielding regions 74a and 74b are respectively The legs have an isosceles trapezoidal shape along the diagonal line of the display screen 14.
(12) Second Depth Display State As shown in FIG. 16B, the left and right shielding members 41a and 41b are in a large trapezoidal advance state, and the upper and lower shielding members 41c and 41d are in a fully retracted state. In the second depth display state, the left and right shielding members 41a and 41b shield the display screen 14 in an isosceles trapezoidal shape with the left and right edges of the display screen 14 as the bottom sides, respectively. As a result, the non-shielding region 71 of the display screen 14 has a pair of upper and lower trapezoidal shapes that form an isosceles trapezoidal shape with the upper and lower edges of the display screen 14 being the bottom sides and reducing the width toward the center of the display screen 14, respectively. The non-shielding regions 74c and 74d and the rectangular non-shielding region 73 formed in the center of the display screen 14 and formed between the trapezoidal non-shielding regions 74c and 74d. The rectangular non-shielding area 73 in the second depth display state is the same as the first depth display state, and the trapezoidal non-shielding areas 74c and 74d are equiped legs that have respective legs along the diagonal line of the display screen 14. It has a shape.

  Note that the above states (1) to (12) are only part of the convertible state of the screen shielding device 17, and the screen shielding device 17 includes four sets of shielding members 41 a to 41 d as described above. By converting to the state, the state can be converted into 1296 (sixth power of 6) states, and the display screen 14 can be shielded with 1000 or more patterns.

  As described above, the screen shielding device 17 includes four sets of the shielding members 41a to 41d in the middle trapezoidal advance state where only the first shield plate 50a is the advance position, and the second shield plate 50b and the third shield plate 50c. Therefore, the non-shielding region 71 can be reduced to a similar shape on the display screen 14 by converting the shielding members 41a to 41d to these states. The display screen 14 can be shielded in various forms such as an X shape.

  Moreover, each shielding member 41a-41d of the screen shielding apparatus 17 is a small thing of the grade which can shield gradually the whole triangular area | region 70a-70d by making all the three shielding plates 50a-50c continue, Furthermore, in the fully retracted state where the display screen 14 is retracted from the front side, the shielding plates 50a to 50c can be compactly accommodated around the display screen 14 by overlapping. For this reason, even if the screen shielding device 17 of the present embodiment includes the shielding members 41a to 41d on the top, bottom, left and right of the display screen 14, it does not become bulky. Since the size of the slot machine is substantially standardized according to the installation space of the amusement hall, a large-scale production device cannot be arranged inside the housing. It can be appropriately accommodated in the casing of an existing slot machine. Therefore, if such a screen shielding device 17 is arranged in an existing slot machine, the display screen 14 can be shielded in various forms, and an interesting production without getting bored of the player is possible.

  Further, in the present embodiment, the second shielding portions (second shielding plate 50b and third shielding plate 50c) of the shielding members 41a to 41d are only moved to the advanced position by the driving means 49. It can be converted to an intermediate state. For this reason, the display screen 14 can be shielded in more various shapes by converting the second shielding portions of the shielding members 41a to 41d to the intermediate state and converting the screen shielding device 17 to the small size display state or the like. There are advantages.

  In the present embodiment, the driving means 49 is provided for each of the shielding members 41a to 41d, and the state of the four sets of shielding members 41a to 41d can be converted for each of the shielding members 41a to 41d. ing. For this reason, the advantage that the screen shielding device 17 can be converted into a state such as the diagonal display state or the depth display state by controlling some of the shielding members 41a to 41d to be different from the other shielding members 41a to 41d. There is. As will be described later, in this embodiment, an image that matches the shape of the non-shielding region 71 is displayed on the display screen 14 in a diagonal display state or depth display state of the screen shielding device 17, thereby providing an interesting production. Realized.

That is, data for generating an image displayed on the display screen 14 during the screen shielding effect is stored in the ROM of the image control board 22. When the image control board 22 receives a command from the sub-control board 21, the CPU performs arithmetic processing, writes effect image data in the RAM and outputs it to the image display 10, and the effect pattern selected by the sub-control board 21. A street effect image is displayed on the display screen 14 of the image display 10.

  In the slot machine 1 of the present embodiment, as described above, the screen shielding effect in which the screen shielding device 17 shields the display screen 14 is executed during the game. Further, in the screen shielding effect, a required image is displayed on the display screen 14 in accordance with the operation of the screen shielding device 17, and an effect combining the operation of the screen shielding device 17 and the display content of the image display 10 is executed. The As described above, in this embodiment, the non-shielding area 71 of the display screen 14 can be changed into various shapes by the screen shielding device 17, and as described below, in this embodiment, the non-shielding area 71 is used. Various screen shielding effects utilizing the shape of the are realized. Specifically, in the present embodiment, screen shielding effects are executed in the following battle introduction effects, stage selection effects, step-up effects, and the like. The details of each production will be described below.

Below, a battle introduction effect is demonstrated.
The battle introduction effect is an effect executed at the start of a so-called battle effect. The battle effect is an effect in which an effect image in which a teammate character and an enemy character battle each other is displayed, and the player is notified whether or not the winning state is in a gaming state advantageous to the player. In the present embodiment, a plurality of types of enemy characters are prepared to fight against a teammate character in a battle effect, and the degree of expectation of winning in the battle effect is suggested by the enemy character that is fighting. That is, which enemy character is to be played is a place where the player pays great attention in battle production. An effect that reveals the enemy character of the opponent at the start of the battle effect is the battle introduction effect.

  In the battle introduction effect, the battle screen is displayed by displaying the images H1 and H2 of the opposing characters and enemy characters in two diagonal division regions 72a to 72d obtained by dividing the display screen 14 by one diagonal line D1 and D2. Clarify enemy characters that will compete in the production. Here, in the battle introduction effect, by converting the screen shielding device 17 to the diagonal display state, the diagonal division regions 72a to 72d where the enemy character image H2 is displayed are shielded, and the screen shielding device 17 displays the diagonal line. A screen shielding effect (diagonal effect) that reveals the enemy character to be played is executed in accordance with the conversion from the state to the fully open state.

  The battle introduction effect will be specifically described based on one effect example. First, before the start of the battle introduction effect, as shown in FIG. 18A, the screen shielding device 17 is in a fully opened state, and the image R for normal effect is displayed on the display screen 14. Then, at the start of the battle introduction effect, as shown in FIG. 18 (b), the display screen 14 is divided into diagonal upper left and lower right diagonal division areas 72a and 72b along the diagonal line D1, and the upper left diagonal division area 72a has a teammate character. The image H1 is displayed. At this time, only the background is displayed in the lower right diagonal segment area 72b. Then, after the image shown in FIG. 18B is displayed for several seconds, the diagonal effect is started. That is, as shown in FIG. 18C, the screen shielding device 17 converts to the first diagonal display state and the lower right diagonal segment 72b is shielded. At the stage of the first diagonal line display state, the enemy character image H2 is displayed in the lower right diagonal line segment 72b as shown in FIG. 18D, but the diagonal line segment area 72b is shielded. Therefore, at this stage, the player cannot determine which enemy character image H2 is displayed. Then, when a few seconds have elapsed since the conversion to the first diagonal line display state, as shown in FIG. 18D, the screen shielding device 17 is converted to the fully open state and displayed in the lower right diagonal division region 72b. The image H2 of the enemy character can be viewed, and the enemy character of the opponent is revealed. Then, when the state shown in FIG. 18D is displayed for a while, the battle introduction effect ends, and the battle effect in which the teammate character displayed in the diagonally divided areas 72a and 72b battles the enemy character is started.

  In the diagonal line effect, a partial disclosure effect that allows a portion of the shielded diagonal line segment 72b to be visually recognized is executed a plurality of times before the screen shielding device 17 converts the first diagonal line display state to the fully open state. The The disclosure effect includes a first partial disclosure effect that enables the central portion of the display screen 14 to be visually recognized, and a second partial disclosure effect that enables the diagonal portion of the display screen 14 to be visually recognized.

  In the first partial disclosure effect, as shown in FIG. 19, a shielding member that shields the diagonal division region 72 b before converting from the diagonal display state (FIG. 19A) to the fully open state (FIG. 19C). The third shielding plates 50c of 41b and 41d move to the retracted position for a very short time (for example, 0.2 seconds) (FIG. 19B) and return to the advanced position. Therefore, in such a first partial disclosure effect, the central portion of the shielded diagonal division area 72b is not shielded for a very short time, and the enemy character shielded by the shield members 41b and 41d is not covered. The image H2 can be partially visually recognized.

  In the second partial disclosure effect, as shown in FIG. 20, the diagonal division area 72b is shielded before conversion from the diagonal display state (FIG. 20A) to the fully open state (FIG. 20C). The first shielding plate 50a of the shielding members 41b and 41d moves in the direction of the retracted position for a very short time (for example, 0.2 seconds) (FIG. 20B) and returns to the advanced position. Therefore, in the second partial disclosure effect, the periphery of the diagonal lines D1 and D2 on the display screen 14 of the shielded diagonal line segment 72b is not shielded for a very short time and is shielded by the shielding members 41b and 41d. The enemy character image H2 can be partially viewed.

  In this way, in the partial disclosure effect, a part of the image H2 can be visually recognized before the entire image H2 of the shielded enemy character becomes clear. By giving a clue to guess the enemy character and stir the player's imagination, the battle introduction effect can be raised.

  FIG. 18 is merely an example of a battle introduction effect. In the battle introduction effect, the image H1 of the teammate character is displayed in the lower right diagonal division area 72b, and the enemy character image H2 is displayed in the upper left diagonal division area 72a. An effect to display is also performed. In such an effect, the screen shielding device 17 is converted to the second diagonal display state, whereby a diagonal effect that shields the upper left diagonal segment 72a is performed. In addition, as shown in FIGS. 21A and 21B, a battle introduction effect is performed in which the display screen 14 is divided into upper right and lower left diagonal division regions 72c and 72d along the other diagonal D2. In this case, the screen shielding device 17 is converted into the third diagonal display state or the fourth diagonal display state, so that the diagonal effect that shields the image H2 of the enemy character displayed in one of the diagonal division regions 72c and 72d. Will be executed.

  Here, in this embodiment, one of the ally character and the enemy character is arranged diagonally upward, and the other is arranged diagonally downward, so that the character arranged diagonally gives a superior impression. be able to. In this embodiment, in the battle introduction effect, when the teammate character has a relatively high expectation to win, the teammate character image H1 is displayed on the diagonally divided regions 72a and 72c on the upper side. When the character's expectation of winning is relatively low, the player's expectation that the teammate character will win in the battle effect is displayed by displaying the image H1 of the teammate character in the diagonally divided diagonal regions 72b and 72d. It can be understood intuitively.

  In this way, in the battle introduction effect, the opposing characters and enemy characters H1 and H2 and the diagonal lines D1 and D2, which are the longest line segments in the display screen 14, are opposed diagonally. Compared to displaying side by side and enemy characters simply side by side, images H1 and H2 of each character can be displayed with a sense of openness while emphasizing the conflicting relationship between the two characters. It is also possible to give a lively feeling to the character images H1 and H2. In the present embodiment, the diagonal division regions 72a to 72d on which the enemy character image H2 is displayed are temporarily shielded by the screen shielding device 17 by the diagonal effect, and then visible to the player. By doing so, it is possible to effectively excite the battle introduction effect that reveals the enemy character.

  Further, the screen shielding device 17 according to the present embodiment selectively turns any two of the four shielding members 41a to 41d into the fully advanced state and sets the remaining two into the fully retracted state, so that an arbitrary diagonal division region 72a is obtained. -72d can be shielded, so that the enemy character image H2 can be clarified by the diagonal effect regardless of the diagonally divided regions 72a-72d where the enemy character image H2 is displayed. There is.

  In particular, in the present embodiment, the screen shielding device 17 divides the display screen 14 into four triangular areas 70a to 70d by two diagonal lines D1 and D2, and is divided into four triangles by four sets of shielding members 41a to 41d. Since the regions 70a to 70d are individually shielded, the individual shielding members 41a to 41d are small enough to shield the triangular regions 70a to 70d obtained by dividing the display screen 14 into four parts. Even if four sets of members 41a to 41d are provided, the screen shielding device 17 is not bulky, and the screen shielding device 17 is reasonably accommodated in a case of a slot machine of an existing size, and the display screen 14 is displayed in four types of diagonal display states. There is an advantage that can be shielded.

The stage selection effect will be described below.
The production of the slot machine 1 according to the present embodiment includes a plurality of stages whose production contents are characterized by characters, scenes, and the like, and the stage selection production is executed as production when switching between these stages. In this stage selection effect, three screen shielding effects of an image reduction effect, a depth effect, and an image enlargement effect are executed in order. The image reduction effect is an effect in which the stage image S1 indicating the current stage is reduced and displayed in accordance with the reduction of the non-shielding area 71. Further, the depth effect is an effect of displaying a plurality of stage images S1 to S5 in a manner having a feeling of depth. Further, the image enlargement effect is an effect in which the stage image S2 indicating the next stage is enlarged and displayed in accordance with the enlargement of the non-shielding area 71.

The stage selection effect will be described based on the example effects shown in FIGS.
As described above, in the stage selection effect, first, an image reduction effect is executed. In the image reduction effect, the screen shielding device 17 is controlled to be fully opened, and the entire display effect is displayed in which the stage image S1 indicating the current stage is displayed in the non-shielding region 71 (the entire display screen 14) (FIG. 22A). And a reduced display effect (see FIG. 22B) in which the screen shielding device 17 is converted into a small size display state and the same stage image S1 is reduced and displayed in accordance with the reduced size of the non-shielded area 71. Are executed in order.

  The stage image includes characters indicating the content of each stage and a display object such as a background. In the example shown in FIGS. 22A and 22B, the stage image S1 includes “ The display size of the characters “Stage 1” is reduced in accordance with the reduction of the non-shielding area 71. Specifically, the non-shielding area 71 in the small size display state has a similar shape in which the vertical and horizontal dimensions of the display screen 14 are reduced to 1/3 times. In the reduced display effect, “Stage1” included in the stage image S1 is displayed. Characters are displayed with the vertical and horizontal dimensions reduced to 1/3 times that of the entire display effect.

  Thus, in the image reduction effect, the stage image S1 displayed in the non-shielding area 71 is reduced and displayed in accordance with the reduction of the non-shielding area 71. Here, in such an image reduction effect, since the non-shielding area 71 is converted to have a similar shape before and after reduction, the stage image S1 is reduced in shape while maintaining the aspect ratio. The stage image S1 can be reduced and displayed without a sense of incongruity.

  In particular, in such an image reduction effect, since the reduced display effect is executed following the overall display effect in which the stage image S1 is displayed on the entire display screen 14, the player is given an impression that the display screen 14 has been reduced. In addition, there is an advantage that it is possible to execute a sharp effect that makes the most of the size of the display screen 14.

  Further, in such an image reduction effect, the non-shielding area 71 is reduced and displayed with reference to the center of the display screen 14, so that the stage image S1 that is reduced together with the non-shielding area 71 can be viewed away from the player. it can.

  In the stage selection effect, the depth effect is executed after the image reduction effect. In such an effect example, as shown in FIG. 23, the screen shielding device 17 is converted into the first depth display state, and an image with a sense of depth is displayed in the non-shielding region 71 in the first depth display state. As described above, when the screen shielding device 17 is converted to the first depth display state, as shown in FIG. 16A, the central rectangular non-shielding region 73 and the trapezoidal non-shielding regions 74a and 74b on both sides are obtained. A non-shielding region 71 is formed which is reduced in width from the left and right edges of the display screen 14 toward the center.

  First, in this depth effect, as shown in FIG. 23, a stage image S1 indicating the current stage is displayed in the rectangular non-shielding area 73, and the left and right trapezoidal non-shielding areas 74a, 74b Stage images S2 and S3 indicating the stage are displayed. Here, the stage images S1 to S3 are such that the left and right trapezoidal non-shielding regions 74a and 74b are planes inclined in the depth direction, and the central rectangular non-shielding region 73 is in the recessed position. The size of a display object such as a character or background is deformed so as to be a plane facing the front. The rectangular non-shielding area 73 is the same as the non-shielding area 71 in the small size display state, and the stage image S1 reduced by the image reduction effect is continuously displayed in the rectangular non-shielding area 73.

  Specifically, in the depth effect, the size of the display object of each of the stage images S1 to S3 displayed in the non-shielding area 71 is deformed so as to converge to the center of the display screen 14 according to the one-point perspective method. The For example, in FIG. 23, in the stage image S1 displayed in the central rectangular non-shielding area 73, the display object is reduced and displayed in accordance with the size of the rectangular non-shielding area 73. That is, the rectangular non-shielding area 73 is an area having a shape in which the vertical and horizontal dimensions are reduced to 1/3 times with respect to the center of the display screen 14, and thus the stage image S1 displayed in the rectangular non-shielding area 73. Is displayed in a reduced size of 1/3 in the vertical and horizontal dimensions as compared with the case where the display is displayed on the entire display screen 14 (see FIG. 22A).

  Further, in FIG. 23, the stage images S2 and S3 displayed in the trapezoidal non-shielding regions 74a and 74b are displayed on characters and backgrounds so that the trapezoidal non-shielding regions 74a and 74b are inclined in the depth direction. The horizontal width of the display object such as is displayed narrower than the vertical width. In addition, the vertical and horizontal dimensions of each display object are enlarged or reduced so as to be proportional to the vertical width of the trapezoidal non-shielding regions 74a and 74b at the display position. Specifically, the vertical width of the trapezoidal non-shielding regions 74 a and 74 b is the vertical width of the display screen 14 on the edge side of the display screen 14, and the vertical width of the display screen 14 on the center side of the display screen 14. The width is reduced to 1/3. Therefore, the display objects displayed in the vicinity of the edge of the display screen 14 in the trapezoidal non-shielding regions 74a and 74b are displayed with a vertical width close to that when the stage images S2 and S3 are displayed on the entire display screen 14. From there, the vertical and horizontal dimensions are reduced as the display is closer to the center of the display screen 14, and the display object displayed near the center of the display screen 14 is the display object displayed near the edge. In comparison, the vertical and horizontal dimensions are reduced to about 1/3.

  In this way, in the depth effect, the non-shielding area 71 is reduced in width toward the center, and the display objects of the stage images S1 to S3 are enlarged and displayed in proportion to the width of the non-shielding area 71 at the display position. The For this reason, the stage images S1 to S3 are visually recognized as images having a sense of depth such that the display object displayed closer to the center is farther away and the display object displayed closer to the edge is closer. Here, in the depth effect, the display screen 14 is shielded by the shielding members 41c and 41d to form the non-shielding region 71 that is reduced in width toward the center, so that the stage images S1 to S1 displayed in the non-shielding region 71 are displayed. The sense of depth in S3 can be emphasized. In other words, the shape of the non-shielding region 71 is reduced toward the center by forming the contour line of the non-shielding region 71 by the shielding members 41c and 41d having a thickness that is actually different from that of the display screen. This makes it easy to create an illusion that there is a depth in the central portion of the non-shielding region 71. Further, the depth of the image of the non-shielding region 71 can be emphasized by moving the shielding members 41c and 41d to the front side of the display screen 14 and positioning the display screen 14 shielding members 41c and 41d on the back side. As described above, according to the depth effect, the screen shielding device 17 is converted into the depth display state in accordance with the display of the stage images S1 to S3 having a sense of depth on the display screen 14, thereby displaying on the display screen 14. The depth feeling of the stage images S1 to S3 to be performed can be improved. Therefore, according to the slot machine 1 of the present embodiment, it is possible to realize an image rich in depth without using an expensive device such as a 3D display.

  In particular, in such a depth effect, the trapezoidal non-shielding regions 74a and 74b have an isosceles trapezoidal shape along the diagonal lines D1 and D2 toward the center of the display screen 14, respectively. Since the display objects of the stage images S1 to S3 displayed on the screen 71 are enlarged and reduced in accordance with the one-point perspective method so as to converge at the center of the display screen 14, the shape of the non-shielding region 71 and the non-shielding region 71 are displayed. Due to the synergistic effect of the stage images S <b> 1 to S <b> 3 displayed on the screen, there is an advantage that the sense of depth that converges at the center of the display screen 14 can be emphasized.

  In the depth effect, as shown in FIG. 23, the current stage image S1 and the other stage images S2 and S3 are statically displayed in a display manner with a feeling of depth, and then the stage images S1 to S3 are displayed in the horizontal direction. Scroll effect is performed to switch the stage images S1 to S3 displayed in the rectangular non-shielding area 73 and the trapezoidal non-shielding areas 74a and 74b. In the scroll effect, for example, as shown in FIGS. 24A to 24D, the stage image S2 displayed in the left trapezoidal non-shielding area 74a is displayed in the rectangular non-shielding area 73 in the rectangular non-shielding area 73a. The stage image S1 displayed at 73 is scrolled to the trapezoidal non-shielding region 74b on the right side. In accordance with this, the stage image S3 displayed in the right trapezoidal non-shielding region 74b is scrolled so as to be outside the right outer side of the display screen 14, and the left trapezoidal non-shielding from the left outer side of the display screen 14 is performed. A new stage image S4 scrolls in the region 74a.

  In such a scroll effect, as shown in FIGS. 24A to 24D, display objects such as characters and backgrounds included in the stage images S1 to S4 are displayed in the non-shielding area 71 during scrolling. Scaled dynamically as the position changes. That is, the display object that scrolls the trapezoidal non-shielding regions 74 a and 74 b is reduced as it scrolls in the center direction of the display screen 14 so as to be proportional to the vertical width of the display position, and in a direction away from the center of the display screen 14. Enlarged as you scroll. On the other hand, the display object that scrolls the rectangular non-shielding area 73 is displayed in the same size as when the scroll is not performed.

  Thus, in such a scrolling effect, the display sizes of the display objects of the stage images S1 to S4 are displayed as the stage images S1 to S4 scroll to the right and the display position in the non-shielding area 71 changes. Since the position dynamically changes according to the vertical width of the non-shielding area 71 of the position, the depth feeling of the image is further emphasized as compared with the case where the stage images S1 to S3 are statically displayed in the non-shielding area 71. can do.

  In the scroll effect, as shown in FIGS. 24A to 24D, when the stage images S1 to S4 start to scroll to the right, the left side of the stage images S1 to S4 is moved in accordance with the movement of the stage images S1 to S4. The first shielding plate 50a of the shielding member 41a temporarily moves from the retracted position to the advanced position. According to such a configuration, the first shielding plate 50a that advances to the right allows the player to visually recognize as if the stage images S1 to S3 are pushed and scrolling is started.

  In addition, although the scroll effect was demonstrated taking FIG.24 (a)-24 (d) as an example, the scroll effect performed during a depth effect is not restricted to once, and may be repeated several times, As shown in FIGS. 25A to 25C, the stage images S1 to S3 and S5 may be scrolled to the left. When the stage images S1 to S3 are scrolled to the left, at the start of scrolling, the first shielding plate 50a of the right shielding member 41b is temporarily moved from the retracted position in accordance with the movement of the stage images S1 to S3. Move to. In addition, the moving direction of the stage images S1 to S3 may be reversed during the scroll effect.

  In the example of the depth effect shown in FIGS. 23 to 25, the screen shielding device 17 is converted into the first depth display state. However, in the stage selection effect, as shown in FIG. A depth effect that converts to a two-depth display state is also executed. In the depth effect in the second depth display state, the non-shielding area 71 includes a central rectangular non-shielding area 73 and upper and lower trapezoidal non-shielding areas 74c and 74d. It becomes the shape which shrinks | deviates toward. Then, as shown in FIG. 26, a stage image S1 indicating the current stage is displayed in the rectangular non-shielding area 73, and stage images S2 and S3 indicating other stages are displayed in the upper and lower trapezoidal non-shielding areas 74c and 74d. Is displayed. In the scroll effect during the depth effect, the stage images S1 to S3 are scrolled up and down. Since the depth effect is a form obtained by rotating the depth effect in the first depth display state by 90 °, detailed description thereof is omitted.

  In each stage selection effect, only one of the depth effect in the first depth display state and the depth effect in the second depth display state may be executed. However, during the execution of one depth effect, the other depth In some cases, it may be switched to production. In each stage selection effect, whether to execute the depth effect in the first depth display state or the second depth display state (or both) may be determined by lottery or based on the player's switch operation May be. In addition, when determining the depth display state by lottery, the degree of expectation of a gaming state advantageous to the player varies depending on which depth effect is executed, the first depth display state or the second depth display state. You may do it.

  In the stage selection effect, as described above, in the depth effect, the stage images S1 to S5 are scrolled left and right, and the stage images S1 to S5 displayed in the rectangular non-shielding area 73 are changed, and then the image enlargement effect is performed. Executed. In the image enlargement effect, the entire display effect and the reduced display effect are executed in the reverse order of the image reduction effect. That is, in the image enlargement effect, as shown in FIGS. 27A and 27B, the screen shielding device 17 is converted from the depth display state to the small size display state and displayed in the rectangular non-shielding region 73. A reduced display effect for reducing and displaying only the stage image S2 in the non-shielding area 71 is executed. That is, at this time, the stage indicated by the stage image S2 displayed in the non-shielding area 71 (rectangular non-shielding area 73) is the stage to be executed next. Subsequently, in the image enlargement effect, as shown in FIGS. 27 (b) and 27 (c), the screen shielding device 17 is converted from the small size display state to the fully open state, and the stage image S2 that has been reduced is displayed. An overall display effect displayed on the entire screen 14 is executed. Specifically, it is included in the stage image S2 displayed in the non-shielding area 71 as the vertical and horizontal dimensions of the non-shielding area 71 are enlarged three times by conversion from the small size display state to the fully open state. Display objects such as characters and backgrounds are enlarged and displayed three times the vertical and horizontal dimensions as compared with the reduced display effect.

  Thus, in the image enlargement effect, the stage image S2 displayed in the non-shielding region 71 is enlarged and displayed in accordance with the enlargement of the non-shielding region 71, contrary to the image reduction effect. In the image enlargement effect, the non-shielding area 71 is converted to have a similar shape before and after the enlargement, so that the stage image S2 is changed to the shape of the enlarged non-shielding area 71 while maintaining the aspect ratio. The stage images S2 can be enlarged without a sense of incongruity.

  In addition, in the image enlargement effect, the overall display effect in which the stage image S2 is displayed on the entire display screen 14 is executed following the reduction display effect, so that the player is given an impression that the display screen 14 is enlarged. In addition, there is an advantage that it is possible to execute a sharp effect that makes the most of the size of the display screen 14. Further, in the image enlargement effect, the non-shielding area 71 is enlarged and displayed with the center of the display screen 14 as a reference, so that the stage image S2 that is enlarged together with the non-shielding area 71 is visually recognized as if approaching the player. Can do.

  The stage selection effect may be executed in accordance with the gaming state, or may be executed when the player operates a predetermined switch in a predetermined manner. Further, the stage selection effect can be an effect that causes the player to select the next stage. For example, when the player operates various switches in the state of the depth effect shown in FIG. 23, the stage images S1 to S3 displayed in the non-shielding area 71 are scrolled one by one, and the player can arbitrarily It is proposed that the stage images S1 to S3 can be displayed in the rectangular non-shielding region 73. Further, during the stage selection effect, it is possible to perform an effect that causes the player to select one of a plurality of options, and the scroll effect is executed only when the player's selection is correct. . In addition, when the scroll effect is executed as a result of the player's selection in this way, the expectation level that will be a gaming state advantageous to the player may be increased.

The step-up effect will be described below.
In the step-up effect, three screen shielding effects of a one-stage effect, a two-stage effect, and a three-stage effect are selectively executed.

  The one-stage effect is an effect in which the screen shielding device 17 is converted from the fully closed state to the small size display state. Specifically, in the one-stage effect, the screen shielding device 17 is converted from the fully closed state to the small size display state, and specified in accordance with the non-shielding region 71 whose vertical and horizontal dimensions are 1/3 times that of the display screen 14. A first display effect is displayed in which a rectangular step-up image T including a character is displayed so as to coincide with the non-shielding area 71. The one-stage effect ends when the first display effect is executed for several seconds. After the end of the one-stage effect, the screen shielding device 17 is converted to a fully closed state and then fully opened, and a normal effect that does not operate the screen shielding device 17 is executed. That is, in the one-stage effect, the display screen 14 changes in the order of (a) → (b) in FIG. 28 and ends at the stage of FIG. 28 (b).

  The two-stage effect is an effect that develops the one-step effect, and the screen shielding device 17 is converted from the fully closed state to the medium size display state through the small size display state. Specifically, the one-stage effect ends after the execution of the first display effect, whereas in the two-stage effect, when the first display effect is executed for several seconds, the screen shielding device 17 is in the small size display state. Is converted to the medium size display state, and the second display effect displayed larger than the first display effect is executed so that the step-up image T matches the non-shielding region 71. Here, the non-shielding region 71 in the medium size display state and the small size display state has a similar shape, and in the medium size display state, the vertical and horizontal dimensions of the non-shielding region 71 are about twice that in the small size display state. In the display effect, the character included in the step-up image T is enlarged and displayed in the non-shielding area 71 with the vertical and horizontal dimensions approximately twice that in the first display effect. The two-stage effect ends when the second display effect is executed for several seconds. After the end of the second display effect, the screen shielding device 17 is fully opened after being converted to the fully closed state, and a normal effect that does not operate the screen shielding device 17 is executed. That is, in the two-stage effect, the display screen 14 changes in the order of (a) → (b) → (c) in FIG. 28 and ends at the stage of FIG. 28 (c).

  The three-stage effect is an effect that further develops the two-stage effect, and the screen shielding device 17 is converted from the fully closed state to the fully closed state through the small size display state and the medium size display state. Specifically, the two-stage effect ends after the execution of the second display effect, whereas in the three-stage effect, when the first display effect is executed for several seconds, the screen shielding device 17 is in the medium size display state. Is converted to a fully opened state, and a third display effect that is displayed larger than the second display effect is executed so that the step-up image T matches the entire display screen 14. Here, the non-shielding region 71 in the medium size display state and the fully open state has a similar shape, and the vertical and horizontal dimensions of the non-shielding region 71 in the fully open state (entire display screen) are about 1.5 times that in the medium size display state. Therefore, in the third display effect, the character included in the step-up image T is displayed on the entire display screen 14 with the vertical and horizontal dimensions of about 1.5 times that in the second display effect. The three-stage effect ends when the third display effect is executed for several seconds. After the completion of the three-stage effect, the screen shielding device 17 is fully opened after being converted to the fully closed state, and a normal effect that does not operate the screen shielding device 17 is executed. That is, in the three-stage effect, the display screen 14 changes in the order of (a) → (b) → (c) → (d) in FIG. 28 and ends at the stage of FIG. 28 (d). Become.

  As described above, in the two-stage effect and the three-stage effect of the step-up effect, the step-up image displayed in the non-shielding area 71 in accordance with the enlargement of the non-shielding area 71 as in the image enlargement effect of the stage selection effect. T is enlarged and displayed. Even in such a two-stage effect or a three-stage effect, the non-shielding region 71 is converted so as to have a similar shape before and after the enlargement, so that the step-up image T is enlarged without maintaining the aspect ratio. There is an advantage that the shape of the region 71 can be matched and the step-up image T can be enlarged without a sense of incongruity. In particular, in the two-stage effect and the three-stage effect, the non-shielding area 71 is enlarged and displayed with the center of the display screen 14 as a reference, so that the game as if the character included in the step-up image T approaches. Can be visually recognized.

  In particular, since the step-up image T expands stepwise from the fully closed state in the two-step effect and the three-step effect, the player's feelings can be raised step by step as the step-up image T expands. it can. In particular, in the step-up effect, even if the first display effect is executed from the fully closed state, the player develops whether the effect ends with the first display effect, or the second display effect or the third display effect. Since it is not possible to determine whether it is, it is necessary to carefully watch the progress of the production. For this reason, in the step-up effect, the player's attention can be attracted to the display screen 14 until the step-up image T is enlarged by the two-step effect or the three-step effect. Can make a strong impression.

  In addition, in the step-up effect described above, an effect that directly develops from the first display effect to the third display effect may be executed without passing through the second display effect as a modification of the two-stage effect or the three-stage effect. Is possible. That is, in this effect, the display screen 14 changes in the order of (a) → (b) → (d) in FIG. 28 and ends at the stage of FIG. 28 (d). In addition, as a modification of the two-stage effect, the first display effect can be executed after the first display effect is developed to the second display effect. That is, in this effect, the display screen 14 changes in the order of (a) → (b) → (c) → (b) in FIG. 28 and ends at the stage of FIG. 28 (b). .

  In the above step-up effects, it is also possible to execute an effect that directly develops from the fully closed state to the second display effect without going through the first display effect as a modification of the two-stage effect or the three-stage effect. It is. In this effect, after the second display effect is executed, the first display effect or the third display effect is executed, so that the effect that the step-up image T is enlarged and the effect that is reduced are selectively selected. It becomes possible to execute.

As described above, in this embodiment, the screen shielding device 17 is operated in accordance with the display image of the image display device 10 to thereby produce an image reduction effect, a depth effect, an image enlargement effect, and a one-stage effect. Screen shielding effects such as two-stage effects and three-stage effects are executed. As described above, since the screen shielding device 17 of the present embodiment can shield the display screen 14 with extremely various patterns, in this embodiment, many screen shielding effects are executed in addition to these screen shielding effects. The Hereinafter, other screen shielding effects executed in the slot machine 1 of this embodiment will be briefly described.
(A) Passage effect The left and right and upper shielding members 41a to 41c are converted to a large trapezoidal advance state, the lower shielding member 41d is converted to a fully retracted state, and directed to the center of the display screen 14 in the non-shielding region 71. By displaying an image of the floor surface that converges, the left and right and upper shielding members 41a to 41c are visually recognized as if they constitute a wall and a ceiling of a deep passage or room.
(B) Partial shielding effect While displaying images suggesting various gaming states on the display screen 14, the image is partially shielded by the shielding members 41a to 41d to determine which image is displayed. This is an effect that enables the user to visually recognize the image by retracting the shielding members 41a to 41d after the person cannot be identified. In this embodiment, since the display screen 14 can be shielded in various shapes by the screen shielding device 17, in such a partial shielding effect, the image on the display screen 14 can be shielded in various forms.
(C) Item Extrusion Effect Displaying an image of an item or the like so as to jump from the outside of the display screen 14 to the center, and moving the shielding members 41a to 41d in accordance with the direction in which the item jumps in, the item Is an effect that makes it appear as if pushed by the shielding members 41a to 41d. In the present embodiment, since the shielding members 41 a to 41 d are arranged on the top, bottom, left, and right, items can be jumped in from the top, bottom, left, and right of the display screen 14.
(D) Winning suggestion effect This is an effect that suggests a winning expectation degree such as a bonus due to the shape of the non-shielding area 71. For example, if the non-shielding area 71 is V-shaped, it indicates that the degree of expectation for the bonus winning is high, and if the non-shielding area 71 is X-shaped, the bonus winning is almost certain. It suggests that. In the present embodiment, since the non-shielding region 71 can be formed in various shapes by the screen shielding device 17, various suggestions are possible as compared with the conventional configuration.
(E) Roulette effect This is an effect of rotating the non-shielding area 71. For example, three of the four triangular regions 70 a to 70 d are completely shielded, and the remaining one is set as a non-shielded region 71. Then, the triangular areas 70a to 70d to be the non-shielding area 71 are switched clockwise in the order of upper → right → lower → left every second. In the present embodiment, the four shielding members 41a to 41d shield the display screen 14 by dividing the display screen 14 into four triangular areas 70a to 70d. Thus, an effect of rotating the non-shielding area 71 is possible.
(F) Achievement level display effect This is an effect that represents the achievement level of the task given during the game by the area of the non-shielding area 71 of the display screen 14. For example, the achievement level of the task is divided into four stages, and each time one stage is achieved, an effect of shielding one triangular region 70a to 70d is performed.
(G) Video shutter effect In the video shutter effect, an image of the shielding member (video shutter) is displayed on the front display screen 14 so that the video shutter shields other images displayed on the display screen 14. Make it visible. Then, by combining the effect by the video shutter with the shielding of the display screen 14 by the shielding members 41a to 41d, the display screen 14 is double-shielded by the shielding members 41a to 41d and the video shutter. Make it visible.
(H) Vibration effect The vibration effect is an effect of vibrating the shielding plates 50a to 50c of the shielding members 41a to 41d. In this embodiment, since the stepping motor 54 can be slightly controlled by finely controlling the step angle of the stepping motor 54, the stepping motor 54 is reciprocally rotated at a fine step angle to shield the stepping motor 54a. The plates 50a to 50c can be easily vibrated with a desired amplitude.

  Although the embodiment of the present invention has been described above, the gaming machine of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the second shielding portion according to the present invention is configured by two shielding plates 50b and 50c, but the second shielding portion according to the present invention is configured by a single shielding plate. Alternatively, it may be composed of three or more shielding plates. Similarly, the 1st shielding part concerning the present invention can be constituted by a plurality of shielding boards. Moreover, in the said Example, a 1st shielding part (1st shielding board 50a) and a 2nd shielding part (the 2nd shielding board 50b and the 3rd shielding board 50c) are converted with one drive source (stepping motor 54). However, the present invention is not limited to this configuration, and the first shielding unit and the second shielding unit may be converted into the advanced state and the retracted state by using separate drive sources (motors and solenoids).

  Moreover, in the said Example, the 2nd shielding part (the 2nd shielding board 50b and the 3rd shielding board 50c) which concerns on this invention makes the trapezoidal 2nd shielding board 50b into an advance position by the drive means 49, and is a triangle. The shape of the third shielding plate 50c is configured to be convertible to an intermediate state at the retracted position, but the configuration of the driving means is changed so that the trapezoidal second shielding plate 50b is at the retracted position and has a triangular shape. You may enable it to convert into the state which the 3rd shielding board 50c becomes an advance position.
