  In the case of the effect device for a gaming machine according to the present invention, the principle that the three-dimensional image is optically formed, so that there is little variation in the appearance and position of the three-dimensional image with respect to the variation in the player's line of sight. There is. On the other hand, a liquid crystal display panel for displaying a parallax barrier image is arranged in front of a liquid crystal display panel for displaying an image for the right eye and an image for the left eye, and a stereoscopic image is virtually perceived. In this case, the three-dimensional image fluctuates depending on the direction of the line of sight looking into the liquid crystal display panel. When such a fluctuation of the three-dimensional image occurs, the player may turn his / her eyes, and the player may fall into a situation similar to seasickness. In this regard, in the case of the effect device for a gaming machine according to the present invention in which the appearance and position of the three-dimensional image are small, the player is less likely to feel discomfort.

Embodiments of the present invention will be specifically described using the following examples.
(Example 1)
This example is a gaming machine that generates a big hit state when a big hit symbol stops, and incorporates a display device 5 that is an example of a rendering device for a gaming machine that displays a three-dimensional image so that a player can view it. It is an example of the pachinko gaming machine 1. This content will be described with reference to FIGS.

  The pachinko gaming machine 1 illustrated in FIG. 1 executes a lottery (special figure determination, big hit lottery) in a jackpot state (special game state) in accordance with a prize in the starting port 12, and executes a symbol change representing the lottery result. It is a so-called Seven machine. In the pachinko gaming machine 1, as a gaming state other than the jackpot state, in addition to the normal state in which the player has a low degree of advantage, a probability variation state (probable variation state) in which the winning probability of special figure determination is increased, and a variation time of the jackpot symbol Is set, for example, when the time is shortened.

  The pachinko gaming machine 1 is a gaming machine having an opening / closing door 13 attached to an underframe (not shown), and having a substantially circular gaming area 130 formed along the surface side of the gaming board 130A inside the pachinko gaming machine. A speaker 131 is arranged at a lower left portion of the game area 130, and an upper plate 135 and a lower plate 137 are provided below the game region 130 so as to project toward the player. The upper plate 135 is a receiving tray for receiving prize balls paid out in accordance with a prize or a lending ball and storing the balls. The lower plate 137 is a plate that receives a ball or the like exceeding the storage limit of the upper plate 135. At the lower right of the upper plate 135, an operation handle 15 for firing the ball of the upper plate 135 toward the game area 130 is provided upright.

  The opening / closing door 13 is fixed to the underframe in a rotatable state via a hinge 133 located on the left side facing the pachinko gaming machine 1. The opening / closing door 13 is provided with a substantially circular transparent window 139 corresponding to the game area 130 and decorative lamp portions 136 arranged on both upper sides of the transparent window 139.

  The game area 130 is an area where a ball as a game medium flows down. In the gaming area 130, a starting port 12, a passing gate 14, a special winning opening 160, and the like are arranged around a display device 5 that displays symbols in a variable manner. The special winning opening 160 is provided below the starting opening 12 so that a ball can be more easily won in a big hit state (special game state) than in a normal state. At the lowermost part of the game area 130, a ball discharge port 138 for opening a ball flowing down without winning is opened. On the left side edge of the game area 130, a general-purpose display unit 182 and a general-purpose reserve display unit 183 made of LEDs are arranged.

  The passing gate 14 is a gate that detects a passing ball. No payout of prize balls is set in the pass gate 14 that only passes balls. When the ball passes through the passage gate 14, a random number for lottery for determining whether or not the symbol is normal (hereinafter, referred to as a general figure determination) is extracted, and the general figure determination is executed. The normal figure winning probability is 1/30 in the normal state, and 1/1 in the probability change state and the time saving state.

The general-purpose display unit 182 is a display unit for displaying the general-purpose determination result. The general-purpose display unit 182 displays the general-purpose winning by lighting the LED, and displays a loss in response to the extinguishing.

The general-purpose reservation display unit 183 displays the number of general-purpose reservations to be retained (upper limit of four) based on the number of lighted LEDs.

  The starting port 12 is a winning port (payout of three balls) that triggers the special figure determination. When a ball is won in the starting port 12 (start winning), a random number for lottery for special figure determination is extracted and a lottery (special figure determination) as to whether or not to generate a big hit state is executed. The starting port 12 is a variable winning port formed by an electric tuy (electric tulip) having a pair of movable blades 121 provided in the opening 120.

  In a normal state, the pair of movable blades 121 are in a state of standing up so as to face each other with a gap therebetween (a state indicated by a dotted line in FIG. 1). In this state, there is a possibility that the ball wins only through the gap for one ball that opens upward. On the other hand, the pair of movable blades 121 (indicated by solid lines in the drawing) rotated so as to be separated from each other acts as a tray for guiding the flow of balls into the opening 120. In such an open state, winning in the starting port 12 easily occurs. The starting port 12 is opened in accordance with the above-mentioned ordinary drawing winning, and the opening time is 0.2 seconds in a normal state and 1.5 seconds × 3 times in a probable change state.

  The special winning opening 160 is a variable winning device also called an attacker. The special winning opening 160 is arranged below the starting opening 12. The horizontally long winning opening 160 is provided with a cover member 161 that can be opened and closed. The special winning opening 160 is closed when the lid member 161 is positioned so as to be substantially flush with the board surface forming the game area 130. When the lid member 161 rotates toward the front side, the special winning opening 160 is opened, and the lid member 161 functions as a tray for guiding the balls to the special winning opening 160. It should be noted that the payout at the time of winning the big winning opening 160 is 15 balls.

  The display device 5 is a display device in which a virtual display area 560, which is a display area for a stereoscopic image, is arranged inside the frame 59. The display device 5 has a function of notifying the result of the special figure determination (big hit lottery), and notifies the result of the special figure determination by a numeric symbol (special image) 560G of the stereoscopic image displayed in the virtual display area 560. Further, on the front surface of the frame 59 corresponding to the lower side of the virtual display area 560, a special figure reservation display unit 597 in which four LEDs are arranged in a horizontal direction is arranged, and the number of special figure reservations is displayed based on the number of lights.

  The display device 5 as the symbol changing means, in the virtual display area 560, displays the numeric symbol 560G of the effect stereo image for a predetermined period of time, and then stops and displays the numeric symbol 560G of the stopped stereo image. The lottery result of the special figure determination is notified. As the lottery result of the special figure determination, there is a loss in addition to the special figure winning (a lottery result to generate a big hit state, a big hit) which triggers the big hit state.

  In the case of the special figure winning, a three-digit numerical symbol (any one of 1 to 9) 560G is displayed after the symbol is varied for a predetermined symbol variation time (the symbol variation execution time). In particular, the odd-numbered symbol pattern 560G has a probability variable jackpot pattern that triggers the probability variable jackpot state, and the even-numbered symbol pattern 560G has a regular jackpot symbol that triggers the regular jackpot state.

The launch control circuit 34 controls the launching strength of the ball by controlling the launch device 341 which is an example of launch means for launching the ball of the upper plate 135 in accordance with the operation amount of the operation handle 15.

  The main circuit 20 shown in FIG. 2 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22 and a RAM (Random Access Memory) 24, which are storage elements, a random number generator 27 that generates random numbers in a predetermined range, and a lottery. A random number extraction unit 26 for extracting random numbers for use, an input / output (I / O) 25 serving as an input / output interface, and the like are provided.

The ROM 22 stores various processing programs to be executed by the CPU 21 and also stores a lottery table for special figure determination and a lottery table for general figure determination (not shown).
In the special drawing determination lottery table, a winning random number of the special figure winning in the normal state and the time saving state and a winning random number of the special figure winning in the probable change state are defined. The number of winning random numbers for the special figure winning in the probable change state is set to be larger than the random number for the special figure winning in the normal state, etc., whereby the probability of the special figure winning in the probable changing state becomes 1/60, and the normal state And the probability of winning in the time reduction state is higher than 1/300. In addition, the distribution ratio of the winning random number of the special figure winning is 50% for the probability variable jackpot and 50% for the normal jackpot.

  In the drawing table for general drawing determination, the random number of the general drawing winning in the normal state and the random number of the general drawing winning in the time saving state and the probable change state are defined. The number of winning random numbers in the time reduction state etc. is set to be larger than the number of random numbers in the normal time winning state in the normal time drawing. The winning probability of the universal map winning in the probable change state is 1/1.

  The RAM 24 is a readable and writable storage element used for a work area of the CPU 21 and temporary writing. To the storage area of the RAM 24, a special figure holding area 241, a general figure holding area 243, and a special figure reading area 245 and a general figure reading area 246 for each data are allocated.

The general-purpose reserved area 243 is a storage area for a reserved random number for general-purpose determination. In the special figure reservation area 241 and the general figure reservation area 243, a reservation area for four data is set.

The main circuit 20 of the present embodiment realizes the following functions by causing the CPU 21 to execute a program read from the ROM 22.
(1) Lottery means: means for executing a special drawing determination, which is a lottery process for determining whether or not to generate a big hit state, when a predetermined lottery condition is satisfied. The lottery means, when a lottery condition of winning a ball to the starting opening 12 is satisfied, extracts a random number for lottery for special figure determination, thereby determining whether or not to generate a jackpot state advantageous to the player. Make a decision.
(2) Storage means: means for storing the random number for lottery extracted for the special figure determination as a reserved random number. The storage means stores the special figure determination random number for special figure determination according to the start winning in the starting opening 12 in the special figure holding area 241. When the corresponding random number for lottery is newly extracted in a state where the reserved random numbers for four data, which is the upper limit, are held, the storage unit deletes the random number for lottery without holding it. Such holding processing of the random number for lottery is the same for the ordinary figure determination.
(3) Reading means: means for reading the reserved random numbers in the special figure holding area 241 and the general figure holding area 243 into the special figure reading area 245 or the general figure reading area 246. The reading means reads the special figure reservation or the general figure reservation, which are the reserved random numbers in the special figure reservation area 241 and the general figure reservation area 243, one by one, and reduces the number of reservations.
(4) Privilege granting means: means for granting a privilege of occurrence of a big hit state to a player when a lottery result of the special figure determination is a special figure win corresponding to grant of a special bonus of occurrence of a big hit state.

  Next, the display device 5 will be described with reference to FIGS. The display device 5 includes a liquid crystal display unit 52 that displays an original image that is an image corresponding to the success or failure of the special figure determination (the result of the jackpot lottery), and a stereoscopic image based on the original image in a predetermined virtual display area 560. Is an effect device that allows a player to visually recognize the numeral pattern 560G and the like. The liquid crystal display unit 52 is an example of an original image display unit that displays an original image that is a source of a three-dimensional image.

  The internal space 500 of the display device 5 is used to form an optical path for displaying a numerical pattern 560G of a stereoscopic image in the virtual display area 560. In this internal space 500, a liquid crystal display unit 52 for displaying an image such as a numeral pattern of an original image is attached to the ceiling, and has a thin plate shape so as to face the liquid crystal display unit 52 at an oblique angle (about 45 degrees). A half mirror 51 is provided. The half mirror 51 is an example of a translucent mirror member having a reflecting surface 510 that reflects a part of the incident light and having an optical property of passing a part of the light incident on the reflecting surface 510. .

  In the display device 5, the display surface 520 of the liquid crystal display unit (original image display unit) 52 faces obliquely with respect to the reflection surface 510 of the half mirror (translucent mirror member) 51. The half mirror 51 is attached so as to reflect the light of the liquid crystal display unit 52 toward the inner surface on the back side of the internal space 500.

  A retroreflective member 53 including a retroreflective surface 530 that returns incident light in the incident direction is disposed on the inner surface on the back side of the display device 5. The retroreflective member 53 has a thin plate shape and is provided along the inner surface on the inner side of the internal space 500. As shown by the optical path indicated by the arrow in FIG. 4, in the display device 5, the light reflected from the half mirror 51 is reflected by the retroreflective member 53 toward the half mirror 51 and returned. As described above, the half mirror 51 has an optical characteristic of passing a part of the incident light. Therefore, at least a part of the light reflected by the retroreflective member 53 passes through the half mirror 51 and goes to the virtual display area 560.

  As described above, the retroreflective member 53 has an optical characteristic of returning incident light in the incident direction. In the configuration of the display device 5, as shown by an arrow in FIG. 4, light generated from the liquid crystal display unit 52, reflected by the half mirror 51, and incident on the retroreflective member 53 is reflected by the retroreflective member 53 in the incident direction. returned. As shown by the arrow in FIG. 4, light generated from a certain pixel on the display surface 520 of the liquid crystal display unit 52 and incident on the retroreflective member 53 does not depend on the arrival path of the light, but is virtually displayed by the optical characteristics of the retroreflective member 53. It is collected at one point in the area 560. In this manner, the light of each pixel on the display surface 520 of the liquid crystal display unit 52 is collected at one corresponding point. Thus, the original image displayed on the display surface 520 of the liquid crystal display unit 52 is formed as a stereoscopic image in the virtual display area 560.

  That is, in the display device 5 of the present example, at least a part of the light from the original image displayed by the liquid crystal display unit 52 is bent by being reflected by the reflection surface 510 of the half mirror (semi-transparent mirror member) 51 to be a retroreflective member. The light reflected by the retroreflective member 53 passes through the half mirror 51 to form a three-dimensional image.

  In this example, the virtual display area 560 is formed inside the opening 590 surrounded by the frame 59 and at a position substantially flush with the transparent window 139 and the front surface of the frame 59. Optical design. This virtual display area 560 is located closer to the player in the depth direction than the game area 130 formed in the gap between the transparent window 139 and the game board 130A. Therefore, for the player, the figure 560G of the three-dimensional image of the virtual display area 560 appears to jump out of the character such as the special winning opening 160 arranged in the game area 130.

  Next, the contents of the game of the pachinko gaming machine 1 configured as described above will be described. When the operation handle 15 is operated in the clockwise direction, the pachinko gaming machine 1 fires a ball at an intensity corresponding to the operation amount. The shot ball flows down the game area 130 where the starting port 12 and the like are arranged. Balls that do not win the starting port 12 or the special winning port 160 are collected from the ball discharge port 138 provided at the bottom of the game area 130.

  When detecting a ball passing through the passage gate 14, the main circuit 20 executes a lottery for extracting a random number for lottery determination from among the random numbers generated by the random number generation unit 27. The main circuit 20 collates the random number for lottery with a lottery table (not shown) for determining the general figure, and determines whether or not to perform the general figure determination. When the general figure determination is won, the main circuit 20 turns on the LED after the blinking operation of the LED constituting the general figure display unit 182 (normal figure fluctuation). In the case of a loss, the LED is turned off after the blinking operation. When winning the ordinary figure determination, the main circuit 20 rotates the movable blade 121 outward, whereby the starting port 12 is opened and the winning probability is increased.

  When a ball flows into the starting port 12 and a start winning is generated, the main circuit 20 executes a special figure determination by extracting a random number for lottery for the special figure determination. The main circuit 20 stores the extracted random number for lottery for judging the special figure as a special figure reservation. The random number for lottery is reserved up to four, which is an example of the upper limit reserved number. When the number of holds is four, a new random number for lottery extracted according to the winning in the starting port 12 is deleted without being stored as a special figure hold. Note that the number of special figure reservations is indicated by the number of lighted LEDs of the special figure reservation display section 597.

  The main circuit 20 outputs the reserved random number stored in the special figure retaining area 241 when the symbol change of the stereoscopic image displayed on the virtual display area 560 as the aerial display is stopped and the big hit state is not occurring. It is read out one by one and collated with a special drawing determination lottery table (not shown) to determine whether the special figure determination is correct or not. When reading the reserved random numbers, the stored random numbers are sequentially read one by one starting from the oldest stored random number (winning time).

  When the main circuit 20 determines whether or not to perform the special figure determination, the liquid crystal display unit 52 is controlled such that the design change of the stereoscopic image is displayed in the virtual display area 560. The three numerical symbols 560G of the three-dimensional images displayed in the virtual display area 560 are stopped in the order of left → right → middle.

  At the time of the special figure winning (big hit) which triggers the jackpot state, first, the same state is stopped on the left and right, and a reach state in which the center symbol is changing occurs (FIG. 5 (a)). In the case of the special figure winning, the same symbol stops at the center after that, and the big hit symbol which is a combination of the double eyes is stopped and displayed in the virtual display area 560 to notify the big hit (FIG. 5B). . At this time, if the special figure win is a probable jackpot, an odd number of doubles is obtained, and if the special figure win is a normal jackpot, an even number of doubles is obtained. On the other hand, when the special figure determination is a loss, after the reach state of FIG. 5A, a symbol different from the left and right symbols is stopped at the center, whereby a loss is notified (FIG. 5C). .

  When the special figure winning is notified by the stop display of the big hit symbol (FIG. 5B), first, an opening effect is executed for 15 seconds, and then the big hit state is started. In the jackpot state, a round in which the special winning opening 160 is opened and a ball can be won is repeatedly executed. During the occurrence of the jackpot state, the main circuit 20 outputs a jackpot signal indicating the fact to the outside.

  The number of repetitions of the round in which the special winning opening 160 is opened during the execution of the jackpot state is 15 times regardless of whether the player is in the probable jackpot state or the normal jackpot state. One round ends when 10 balls are won in the special winning opening 160 or 30 seconds have elapsed. The average payout for 15 rounds is about 1500. When the round is digested 15 times in the jackpot state, the ending effect for 10 seconds is executed and the jackpot state ends.

  After the end of the probable change jackpot state, a probable change state occurs in which the probability of winning a special map win increases. This probable change state ends according to the normal jackpot win corresponding to the normal jackpot state (normal jackpot special figure win), and in the case of the probable variable jackpot win (probably variable jackpot special figure win), the corresponding probable change jackpot state After termination, the probable change state is resumed and continued. After the end of the normal jackpot state, a time-saving state over 50 rotations of the symbol fluctuation occurs, and the normal state is restored when the symbol fluctuation of 50 rotations is consumed.

  The pachinko gaming machine 1 of this example has one of the technical features of the display device 5 that displays a stereoscopic image. The display device 5 is a presentation device that displays a stereoscopic image using a retroreflective member 53 including a retroreflective surface 530 that returns incident light in the incident direction. In the display device 5, the display surface 520 of the liquid crystal display unit 52, which is an example of the original image display unit, faces the reflection surface 510 of the half mirror (translucent mirror member) 51 at an angle, and the light from the original image At least part of the light is reflected by the half mirror 51, bent, and enters the retroreflective member 53. The light reflected by the retroreflective member 53 passes through the half mirror 51 and forms a three-dimensional image on the virtual display area 560.

  The display device 5 is an effect device for a gaming machine capable of three-dimensional display with a very simple configuration using the retroreflective member 53 and the half mirror 51, and can be realized at low cost. The pachinko gaming machine 1 incorporating the display device 5 is a highly price-competitive gaming machine that enables stereoscopic display while suppressing an increase in cost.

  In the case of the display device 5 of the present example, since the numeral pattern 560G, which is a stereoscopic image, is optically formed, the stereoscopic image fluctuates little according to a change in the player's line of sight. In the display device 5, the visibility of the numeric symbol pattern 560G is high, and the player is less likely to feel discomfort due to fluctuations of the three-dimensional image.

Instead of or in addition to the configuration of this example, the following configuration may be adopted. Further, the following configurations may be appropriately combined and adopted.
In this example, the pachinko gaming machine 1 is illustrated, but the invention may be applied to other gaming machines. For example, a ball is enclosed, a pachinko machine that consumes points and shoots balls, a slot machine where the game progresses by consuming medals and performing lottery, and a lottery consuming points Thus, a credit-type slot machine or the like in which a game proceeds can be considered. Although the configuration in which the jackpot state or the occurrence of the bonus game is given as a bonus has been described, instead of or in addition to this configuration, a configuration in which one of a medal, a ball, and a score is provided corresponds to the grant of a bonus. It is also possible to make it.

  In this example, the configuration in which the liquid crystal display unit 52 is attached to the ceiling of the internal space 500 of the display device 5 is illustrated, but the liquid crystal display unit 52 may be provided on the bottom surface or the left and right inner side surfaces of the internal space 500. Similarly, the installation position of the retroreflective member 53 is not limited to the position in this example, and can be changed as appropriate. The installation angle of the half mirror 51 may be appropriately changed according to the positions of the liquid crystal display unit 52 and the retroreflective member 53. In this example, an optical path (optical path) of liquid crystal display section 52 → reflection on half mirror 51 → reflection on retroreflective member 53 → passing through half mirror 51 → imaging is exemplified. The optical path may be an optical path of liquid crystal display section 52 → pass through half mirror 51 → reflection on retroreflective member 53 → reflection on half mirror 51 → imaging.

(Example 2)
This example is an example in which a three-dimensional image can be displayed brightly using the polarization direction (polarization plane) of light based on the display device of the first embodiment. The display device 5 of the present embodiment is different from the first embodiment in optical specifications of the liquid crystal display unit 52 and the half mirror 515. Further, in the configuration of the present example, a λ / 4 wavelength plate 55 is newly disposed on the surface of the retroreflective member 53. Hereinafter, this content will be described in detail with reference to FIGS.

  In the display device 5 of the present example, as shown in FIG. 6, a so-called λ / 4 wave plate 55 that gives a phase difference of λ / 4 to the passed light is laminated on the surface of the retroreflective member 53, and thereby, A λ / 4 wavelength plate 55 is interposed between 53 and the half mirror 515. For example, when linearly polarized light passes through the λ / 4 wavelength plate 55, a phase difference of λ / 4 is given to two orthogonal components constituting the light, and the polarized light becomes rotationally polarized light. Further, when the rotationally polarized light passes through the λ / 4 wavelength plate 55 again, a phase difference of λ / 4 is given to two orthogonal components constituting the light, and the light returns to linearly polarized light. Here, the linearly polarized light that has passed through the λ / 4 wavelength plate 55 twice is light whose polarization direction has been rotated by 90 degrees with respect to the original linearly polarized light.

  The liquid crystal display unit 52 of this example, which is an example of the original image display unit, is a display unit of an optical specification that generates vertical linearly polarized light, as shown in FIG. The half mirror 515, which is an example of a translucent mirror member, is a polarizing reflector that selectively reflects or passes incident light according to the polarization direction of incident light. In particular, the half mirror 515 of this example reflects linearly polarized light having a vertical polarization direction generated from the liquid crystal display unit 52 on the reflection surface 510, and rotates the polarization direction by 90 degrees with respect to the linearly polarized light having the vertical polarization direction (that is, the polarization direction is rotated 90 degrees) It exhibits an optical characteristic of transmitting linearly polarized light whose polarization direction is horizontal.

  When the light incident on the retroreflective member 53 passes through the λ / 4 wavelength plate 55 and reaches the surface of the retroreflective member 53, first, a phase difference of λ / 4 is given. When the light is reflected and passes again through the λ / 4 wavelength plate 55 to the outside, a phase difference of λ / 4 is further provided. As a result, a phase difference of λ / 2 is given to the linearly polarized light (the polarization direction is vertical) incident on the retroreflective member 53, whereby the polarization direction of the reflected light is rotated by 90 degrees and horizontally. become. The reflected light having a horizontal polarization direction can pass through the half mirror 515 which is a polarization reflection plate, and can travel toward the virtual display area 560.

  In the display device 5 of this example, linearly polarized light having a vertical polarization direction and generated from the liquid crystal display unit 52 is selectively reflected by the half mirror 515 that is a polarization reflection plate. Therefore, most of the light generated from the liquid crystal display unit 52 can enter the retroreflective member 53. Further, the light that has passed through the λ / 4 wavelength plate 55 twice and reflected from the retroreflective member 53 is a linearly polarized light having a horizontal polarization direction, and most of the light is a half mirror 515 that is a polarization reflection plate. Can pass.

  Therefore, in the display device 5 of this example, the amount of light lost by the half mirror 515 is small, and most of the light of the liquid crystal display unit 52 can reach the virtual display area 560. Therefore, the brightness of the numeral pattern 560G in the virtual display area 560 can be relatively easily secured while suppressing the amount of light generated by the liquid crystal display unit 52.

In this example, a configuration in which a λ / 4 wavelength plate 55 is laminated on the surface of the retroreflective member 53 is illustrated. The configuration in which the λ / 4 wavelength plate 55 is stacked on the surface of the retroreflective member 53 is not essential. The λ / 4 wavelength plate 55 may be provided between the retroreflective member 53 and the half mirror 515.
Further, instead of the configuration of this example, a liquid crystal display unit that generates linearly polarized light having a horizontal polarization direction may be employed. In this case, it is preferable to use a polarizing reflector that reflects linearly polarized light having a horizontal polarization direction and passes linearly polarized light having a vertical polarization direction as the half mirror.
The other configuration and operation and effect are the same as in the first embodiment.

(Example 3)
This example is an example in which the size of a three-dimensional image is made variable based on the display device of the first embodiment. This content will be described with reference to FIG.

  The internal space 500 of the housing 50 of the display device 5 of the present example extends upward as shown in FIG. A slide rail 529 is attached to the inner wall of the extension in the vertical direction. Note that, in the same figure, the slide rail 529 is easily visible by breaking the extension part in the middle and omitting the illustration of the ceiling of the housing 50.

  The liquid crystal display unit 52 is held so as to be able to advance and retreat in the vertical direction via a slide rail 529 that is disposed to face the inner wall of the internal space 500. The liquid crystal display unit 52 is configured to be driven in a vertical direction by a drive mechanism including a drive motor and gears (not shown). When the liquid crystal display unit 52 moves back and forth in the vertical direction, the distance from the liquid crystal display unit 52 to the retroreflective member 53 varies in the optical path from the liquid crystal display unit 52 to the virtual display area 560 as shown in FIG. FIG. 11A shows an example in which the liquid crystal display unit 52 is located at the lower limit and the virtual display area 560 is located at the opening 590. FIG. 13B shows an example in which the liquid crystal display unit 52 moves upward, and the virtual display area 560 protrudes from the opening 590 and is located on the player side.

  In the above optical path, the first half distance from the liquid crystal display unit 52 to the retroreflective member 53 is linked to the second half distance from the retroreflective member 53 to the virtual display area 560. If the distance in the first half becomes longer, the distance in the latter half becomes longer in conjunction with it. In addition, if the distance in the first half becomes shorter, the distance in the latter half becomes shorter in conjunction. For example, as shown in FIG. 8B, when the liquid crystal display unit 52 is moved upward, the virtual display area 560 can be moved to the player side.

A special reach effect including a special effect of moving the virtual display area 560 to the player side using the display device 5 including the driving mechanism illustrated in FIG. 8 may be executed. In this special reach effect, the degree of expectation of special figure winning (big hit) may be suggested according to the position of the virtual display area 560. For example, when the reach state occurs, the position of the virtual display area 560 may be changed. At this time, it can be suggested that the expectation of the special figure winning is high according to the position of the virtual display area 560. Further, for example, the position of the virtual display area 560 may be gradually approached to the player while the reach state is continued (while the symbol at the center is changing). Depending on how close the virtual display area 560 approaches the player, the degree of expectation of special figure winning can be suggested.
The other configuration and operation and effect are the same as in the first embodiment.

(Example 4)
This example is an example in which the retroreflective member 531 is added and the double-sided half mirror 511 is employed based on the display device of the first embodiment. This content will be described with reference to FIG.
In the configuration of the present example, a retroreflective member 531 is also provided on the bottom surface of the internal space 500 in addition to the retroreflective member 53 on the inner side surface on the inner side of the internal space 500 of the display device 5. Further, instead of the half mirror (reference numeral 51 in FIG. 4) of the first embodiment, a double-sided half mirror 511 having a sufficiently small thickness is employed. The double-sided half mirror 511 is a semi-transparent mirror member having reflection surfaces 510 provided on both sides thereof.

  The retroreflective member 531 on the bottom surface of the internal space 500 reflects light generated from the liquid crystal display unit 52 and passing through the double-sided half mirror 511 as shown by the arrow in FIG. . Here, the double-sided half mirror 511 has an optical characteristic of passing a part of the incident light. Therefore, at least a part of the light reflected by the retroreflective member 531 is reflected by the double-sided half mirror 511 and travels to the virtual display area 560.

In the display device 5 of the present example, the light from the retroreflective member 53 on the back side of the internal space 500 and the light from the retroreflective member 531 on the bottom surface are combined to form an image on the virtual display area 560. Therefore, the light amount of the three-dimensional image increases, and the three-dimensional image becomes bright.
The other configuration and operation and effect are the same as in the first embodiment.
