Abstract:
An object of the present invention is to provide an image mutual transfer and succession method between a virtual image and a real image capable of performing the smooth transfer between the display of a virtual image of a real item and the display of a real image, realizing the successful combination of the reality of the real item and the fantasy of the real image, and enabling a rich representation.  
     The image mutual transfer and succession method between a virtual image and a real image according to the present invention performs take-over control of mutual images by structuring the real image of the display to be apparently identical to the virtual image, displaying the real image on the display in synchronization with the dimming of illumination to the real item when displaying the real image, and brightening the illumination to the real item in synchronization with the stoppage of the real image display on the display device when displaying the virtual image.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to an image mutual transfer and succession method of a virtual image and real image, and more particularly to a method of transferring a virtual image display reflecting a real item on a half mirror into a real image display, or transferring a real image display into a virtual image display reflecting a real item on a half mirror.  
           [0003]    2. Description of the Related Art  
           [0004]    Conventionally, as a game machine employing an image display device using a virtual image, there is a target-hammering game device disclosed in the specification of Japanese Patent Application Laid-Open No. 8-323037.  
           [0005]    This target-hammering game machine displays the target image projected on the CRT screen to the player by synthesizing the virtual image of the hammering table pursuant to the operation of a half mirror and the mirror image of the hammer held by the player.  
           [0006]    Upon playing the game, the player plays the game while viewing the screen of the image display device, and swings the hammer such that the hammer, which is a mirror image, collides with the target image.  
           [0007]    When the player hammers the target image successfully, the shock sensor detects this hammering motion and outputs a signal, and, based on such signal, the image control device switches the target image on the CRT screen to a direct hit effect image.  
           [0008]    In addition, there is a synthesized image display device, game device and bowling game device disclosed in the specification of Japanese Patent Application Laid-Open No. 11-114221.  
           [0009]    This synthesized image display device synthesizes an actual ball and an image ball and displays this to the observer, and comprises a CRT display for displaying images, and a mirror for forming a reflective virtual image of such image.  
           [0010]    Upon playing the game, the actual ball rolled by the player rolls on the traveling face, passes by the mirror, and moves further toward the back.  
           [0011]    Then, when the actual ball passes by the half mirror portion of the mirror, an image ball having the same outer appearance as the actual ball appears, and the actual ball switches to this image ball.  
           [0012]    In other words, after the actual ball hides behind the mirror, the image ball as the reflective virtual image continues the movement.  
           [0013]    In addition, the game device disclosed in the specification of Japanese Patent Application Laid-Open No. 11-104311 structures a variable display device with a rotational drum having a special design on the peripheral face thereof; a drum lamp capable of illuminating light to the special design of the rotational drum; a half mirror which visibly transmits the special design pursuant to the illumination from the drum lamp; and a projection display mechanism capable of projecting and displaying the projected image on the half mirror, and the projection display mechanism projects and displays the character design as the projected image on the half mirror.  
           [0014]    According to the foregoing structure, provided is a mechanically variable display device capable of displaying a character design in addition to the display of a special design, and the ornamental visual effect is thereby improved.  
           [0015]    Meanwhile, as described above, the target-hammering game machine disclosed in Japanese Patent Application Laid-Open No. 8-323037 executes the game with the virtual image of the hammer and the background image thereof by employing a half mirror, and merely represents the actual whack-a-mole game machine, which is a well-known and popular game, with an image. Thus, this merely displays a virtual image and does not have a switching structure.  
           [0016]    With the synthesized image display device, game device and bowling game device disclosed in the specification of Japanese Patent Application Laid-Open No. 11-114221, when the actual ball rolled by the player hides behind the backside of the mirror, an image ball as the reflective virtual image continues the movement. Although this yields an advantage in that the occupancy space of the game device can be reduced and the device itself can be simplified by spatially disposing the portion of the real item and the portion of the reflective virtual image separately, the real item in the game machine is merely replaced with an image representation, and thereby lacks variety and diversity.  
           [0017]    Moreover, since an actual ball is moved, a large space is required, and there is a problem in that the game device will become large.  
           [0018]    With the game device disclosed in the specification of Japanese Patent Application Laid-Open No. 11-104311, the player visually recognizes the special design of the rotational drum via the half mirror. Although the projected image is overlapped on the special design of the rotational drum and projecting and displaying the same, the display to the player is mainly structured of the special design of the rotational drum, and this merely adds an image representation employing a virtual image to the periphery of the special design of the rotational drum.  
         SUMMARY OF THE INVENTION  
         [0019]    The present invention was devised in view of the foregoing circumstances, and an object thereof is to provide an image mutual transfer and succession method of a virtual image and a real image capable of performing the smooth transfer from the display of a virtual image of a real item and the display of a real image, realizing the successful combination of the reality of the real item and the fantasy of the real image, and enabling a rich representation.  
           [0020]    In order to achieve the foregoing object, the first aspect of the present invention provides an image mutual transfer and succession method between a virtual image and a real image which switches, as required, between display of a virtual image of a real item as a reflected image by a half mirror and display of a real image as a half mirror transmitted image from a display provided behind said half mirror; wherein mutual take-over control of images is performed by structuring the real image by said display to be apparently identical to said virtual image, displaying the real image on said display in synchronization with the dimming of illumination to said real item when displaying the real image, and brightening the illumination to said real item in synchronization with the stoppage of the real image display on said display device when displaying the virtual image.  
           [0021]    According to the foregoing structure, the transfer and succession between the virtual image display and real image display can be conducted smoothly with the observer hardly noticing.  
           [0022]    Further, similar to a structure of visually recognizing a real item, the successful combination of the reality of the real item and the fantasy of the real image is realized.  
           [0023]    Moreover, by transferring the virtual image display of a real item to the display of a real image, realized is a display employing a real image for changes in the mode of the real item, which is not possible in a structure displaying the real item.  
           [0024]    The image mutual transfer and succession method of a virtual image and a real image according to the second aspect of the present invention is the image mutual transfer and succession method of a virtual image and a real image of the first aspect described above, wherein the real item is a design drawn on the peripheral face of a mechanical reel.  
           [0025]    According to this structure, the transfer and succession between the virtual image of the design on the mechanical reel peripheral face and real image can be conducted smoothly with the observer hardly noticing.  
           [0026]    Therefore, by transferring the virtual image display of the design on the mechanical reel peripheral face to the display of a real image, realized is a display employing a real image for changes in the mode of the mechanical reel, which is not possible in a structure displaying the real item.  
           [0027]    Further, similar to a structure of visually recognizing an actual mechanical reel, the successful combination of the realistic game display of the real item and the virtualistic game display of the real image is realized.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0037]    The present invention is now described in detail with reference to the drawings representing the embodiments.  
         [0038]    [0038]FIG. 1 is a perspective view of the appearance of the slot game machine  1  employing the present invention. FIG. 2 is a longitudinal cross section from the side of such slot game machine  1 .  
         [0039]    In the slot game machine  1 , as shown in FIG. 1, FIG. 2 and FIG. 3, a liquid crystal display panel (display)  5  is provided at a position facing the player p in a protective glass  1   g  through which the player p sees, a half mirror  1   m  is provided in front of the crystal display panel  5  in a lowered and inclined manner, and one set of mechanical reels  6   a ,  6   b ,  6   c  is disposed within the top box  1   p  above the half mirror  1   m.    
         [0040]    An illumination-adjustable reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) for illuminating the designs (real item)  6   an ,  6   bn ,  6   cn  drawn respectively on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  are disposed within the mechanical reels  6   a ,  6   b ,  6   c.    
         [0041]    The slot game machine  1  comprises a virtual image display mode and a real image display mode as its game display mode.  
         [0042]    For example, as shown in FIG. 4, which is a conceptual diagram during the game, the slot game machine  1  foremost displays through the half mirror  1   m  the image  5   e  displayed on the upper area of the liquid crystal display panel  5  on the upper half area  1 Gu of the game display through the protective glass  1   g  as the virtual image display mode, and displays the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the peripheral faces of the mechanical reels  6   a ,  6   b ,  6   c  reflected on the half mirror  1   m  on the lower half area  1 Gs of the game display.  
         [0043]    Next, the reel lamps  6   a   1 ,  6   b   1 ,  6   c   1  are turned off in order to stop the illumination to the designs  6   an ,  6   bn ,  6   cn  of the respective peripheral faces of the mechanical reels  6   a ,  6   b ,  6   c  so as not to display the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn , and, in synchronization therewith, as shown in FIG. 7, a reel peripheral face image  5   e   1  having image designs (real images)  6   an ″,  6   bn ″,  6   cn ″ identical with and positioned the same as the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  is displayed on the lower half area  1 Gs of the liquid crystal display panel  5 , and transfers the virtual image display mode to the real image display mode by displaying the image  5   e  and the reel peripheral face image  5   e   1  on the entire area of the game display  1 G within the protective glass  1   g.    
         [0044]    Contrarily, when transferring the real image display mode to the virtual image display mode, foremost, as the real image display mode, as shown in FIG. 7, the image  5   e  and the reel peripheral image  5   e   1  having image designs  6   an ″,  6   bn ″,  6   cn ″ are displayed on the entire area of the liquid crystal display panel  5 , and the image  5   e  and the reel peripheral face image  5   e   1  are displayed across the entire area  1 G of the game display within the protective glass  1   g.    
         [0045]    Next, as shown in FIG. 6, the reel peripheral face image  5   e   1  of the liquid crystal display panel  5  is non-displayed and a dark color is displayed in place thereof, and, in synchronization therewith, the reel lamps  6   a   1 ,  6   b   1 ,  6   c   1  are turned on to illuminate the designs  6   an ,  6   bn ,  6   cn  of the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  so as to be reflected with the half mirror  1   m , and the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  identical with and positioned the same as the non-displayed image designs  6   an ″,  6   bn ″,  6   cn ″ are displayed, thereby transferring the real image display mode to the virtual image display mode.  
         [0046]    As described above, the slot game machine  1  comprises a virtual image display mode and a real image display mode as its game display mode, and is capable of transferring, when appropriate, the virtual image display mode to the real image display mode, or from the real image display mode to the virtual image display mode.  
         [0047]    As shown in FIG. 1 and FIG. 2, provided to the front face of the aforementioned slot game machine  1  is an operational table It which is protrusively provided in an anteriorly inclined manner at a position where the player p can manually operate the same with ease. Moreover, a transparent protective glass  1   g  is provided above the operational table it so as to enable the player p to see the game space  1   s  within the slot game machine  1  as well as to protect the same.  
         [0048]    Further, as shown in FIG. 2, a top box  1   p  housing the mechanical reels  6   a ,  6   b ,  6   c  is formed above the slot game machine  1 .  
         [0049]    As shown in FIG. 2 and FIG. 3, a liquid crystal display panel  5 , which is a flat panel display, is provided in the game space is protected with the protective glass  1   g  at a position facing the player, and a half mirror  1   m  is disposed at a declining and inclining angle of 45° toward the player side.  
         [0050]    Moreover, although the inclination angle of the half mirror  1   m  is set to 45°, it goes without saying that the inclination angle may be set to an angle other than 45° so as long as the designs  6   an ,  6   bn ,  6   cn  of the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  are reflected on the half mirror  1   m , and the player p is able to visually recognize each virtual image  6   an ′, virtual image  6   bn ′ and virtual image  6   cn′.    
         [0051]    Further, although a liquid crystal display panel  5  is used as the image display device for displaying the game image in the present embodiment, needless to say, other image display devices, such as a plasma display panel, for example, may be used in place of the liquid crystal display panel  5 .  
         [0052]    Moreover, as shown in FIG. 2, the mechanical reels  6   a ,  6   b ,  6   c  are housed in the top box  1   p  and disposed above the half mirror  1   m , and, as shown in FIG. 4, the player p visually recognizes the virtual images  6   an ′, . . . ,  6   bn ′, . . . ,  6   cn ′, . . . , in which the design  6   an , design  6   bn  and design  6   cn  on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  are reflected on the half mirror  1   m , at the lower half area  1 Gs of the game display within the protective glass  1   g.    
         [0053]    The aforementioned mechanical reels  6   a ,  6   b ,  6   c  are formed having a contour of a drum shape, and, at the respective peripheral faces of the mechanical reels  6   a ,  6   b ,  6   c , attached thereto are a design sheet having as its material polycarbonate or the like to which the design  6   an , . . . is to be drawn, a design sheet having as its material polycarbonate or the like to which the design  6   bn , . . . is to be drawn, and a design sheet having as its material polycarbonate or the like to which the design  6   cn , . . . is to be drawn.  
         [0054]    The aforementioned design  6   an , . . . , design  6   bn , . . . and design  6   cn , . . . are classified, for example, as a design with a specific hand such as the number 7, or other general designs.  
         [0055]    The mechanical reels  6   a ,  6   b ,  6   c  structured as described above are each axially supported rotatably around the concentric axis extending horizontally in the left and right directions of the slot game machine  1 , and they respectively have favorable consistency with digital control systems, and are rotatably driven independently in a direct drive with a stepping motor (not shown) which rotates in a prescribed angle.  
         [0056]    And, in order to make each of the mechanical reels  6   a ,  6   b ,  6   c  stop at a prescribed position determined with internal drawing, a position sensor I ( 22   a ), position sensor II ( 22   b ) and position III ( 22   c ) (c.f FIG. 5) are respectively applied for each mechanical reel  6   a ,  6   b ,  6   c  for performing position control.  
         [0057]    Moreover, light sensors such as photodiodes and phototransistors are suitably selected and used as the position sensors  22   a ,  22   b ,  22   c.    
         [0058]    Further, needless to say, the rotational drive of the mechanical reels  6   a ,  6   b ,  6   c  may suitably adopt a transmission mechanism employing a transmission belt or a gear mechanism.  
         [0059]    And, as shown in FIG. 2 and FIG. 3, a reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) for illuminating and conspicuously displaying the design  6   an , . . . ,  6   bn , . . . ,  6   cn , . . . on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  are disposed respectively within the mechanical reels  6   a ,  6   b ,  6   c.    
         [0060]    Here, illumination of the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) can be adjusted pursuant to the increase or decrease of the current, and, by suitably adjusting the illuminance thereof, the design  6   an , . . . ,  6   bn , . . . ,  6   cn , . . . on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  can be displayed in various clearness as the virtual images  6   an ′, . . . ,  6   bn ′, . . . ,  6   cn ′, . . . by being reflected on the half mirror  1   m.    
         [0061]    For example, sharp and clear virtual images  6   an ′, . . . ,  6   bn ′, . . . ,  6   cn ′, . . . can be displayed by increasing the illuminance of the reel lamp  6   a   1 ,  6   b   1 ,  6   c   1 , and obscure and unclear virtual images  6   an ′, . . . ,  6   bn ′, . . . ,  6   cn ′, . . . can be displayed by decreasing the illuminance. Further, by reducing the illuminance to the lowest point, the designs  6   an , . . . ,  6   bn , . . . ,  6   cn , . . . on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  will no longer be displayed as the virtual images  6   an ′, . . . ,  6   bn ′, . . . ,  6   cn ′, . . . by being reflected on the half mirror  1   m , thereby realizing a non-display.  
         [0062]    Moreover, although the reel lamps  6   a   1 ,  6   b   1 ,  6   c   1  are respectively and internally disposed in the mechanical reels  6   a ,  6   b ,  6   c  in the present embodiment, they may be provided outside the mechanical reels  6   a ,  6   b ,  6   c.

         [0071]    The foregoing control program processing are, for example, the drive and stop position control of the respective stepping motors for rotatably driving each mechanical reel  6   a ,  6   b ,  6   c ; game image output control, various processing such as the bet processing pursuant to the input operations of the player and calculation of the balance of the wager; control for printing and ejecting the exchange ticket; flashing operation control of various lamps; game sound output control, and so on.  
         [0072]    Moreover, the EPROM  20   b  has the control data and table for performing the rotational drive stoppage control of the mechanical reels  6   a ,  6   b ,  6   c.    
         [0073]    The tables stored in the EPROM  20   b  are a winning design combination table, stoppage control table of the mechanical reels, and so forth.  
         [0074]    The foregoing winning design combination table stores data prescribing the winning combination design for determining the realization of winning hands, and stores data on the prize to the provided to the player in accordance with the realization of various winning hands.  
         [0075]    Here, the realization of the winning hands determined by the combination of designs displayed on the respective mechanical reels  6   a ,  6   b ,  6   c  in which the rotation has stopped is set by employing a random number arising in a prescribed probability among the random number generated with a random number generator.  
         [0076]    The stoppage control table used in the stoppage control of the mechanical reel is recorded in association with the designs of the respective mechanical reels  6   a ,  6   b ,  6   c  and the arrangement thereof, and, when the relative positional relationship among one of the designs of the respective mechanical reels  6   a ,  6   b ,  6   c  is set forth, the mutual positional relationship of the other designs will be set forth naturally.  
         [0077]    For example, when the number of designs of each mechanical reel  6   a ,  6   b ,  6   c  is 16, designs codes 1 to 16 are respectively provided to the designs  6   an , . . . ,  6   bn , . . . ,  6   cn , . . . of each mechanical reel  6   a ,  6   b ,  6   c , and, with the design of the design code I as the reference, the relative positional relationships of the other designs are recognized, and stoppage control is performed for the respective reels  6   a ,  6   b ,  6   c.    
         [0078]    The foregoing RAM  20   c  generates a work area upon executing the control program, temporarily stores variable data, and so on.  
         [0079]    In other words, stored are data regarding whether the respective mechanical reels  6   a ,  6   b ,  6   c  are rotating or stopped; what designs are displayed on the respective mechanical reels  6   a ,  6   b ,  6   c ; whether the image reel is rotating or stopped, what the image designs are among the designs displayed on the image reel; how much the player p inserted; betting information; balance; won prize; and so on.  
         [0080]    By executing the control program stored in the EPROM  20   b , the CPU  20   a  is able to comprehensively perform the overall control of the slot game machine  1 ; for instance, control of the respective stepping motors for rotatably driving each of the foregoing mechanical reels  6   a ,  6   b ,  6   c ; output processing of the image signal to the image control circuit  20   d ; and various processing according to the input operations of the player.  
         [0081]    The control unit  20  is connected to an external storage device gm such as a CD-ROM, and the external storage device gm creates and stores in advance, as image data of the game, the same number and type of image designs  6   an ″,  6   bn ″,  6   cn ″ as the designs  6   an ,  6   bn ,  6   cn  on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  as well as the representation pattern used in the image  5   e.    
         [0082]    Moreover, the control unit  20  is connected to a stepping motor M 1 , stepping motor M 2  and stepping motor M 3  for respectively driving the mechanical reels  6   a ,  6   b ,  6   c ; a reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) within the respective mechanical reels  6   a ,  6   b ,  6   c ; a position sensor I ( 22   a ), position sensor II ( 22   b ) and position sensor III ( 22   c ) for detecting the rotational position of the respective mechanical reels  6   a ,  6   b ,  6   c , via the interface  21   a  including the motor drive circuit, sensor circuit, and so on.  
         [0083]    Further, the control unit  20  is also connected to a speaker sp for generating game effect sounds via the interface  21   b , this interface  21   b  is a sound circuit for decoding the sound signal and outputting this from the speaker sp as an audio signal.  
         [0084]    In addition, the control unit  20  is also connected, via an interface  21   c  such as a chattering prevention circuit or the like, to a bill validator  24  for reading the bill inserted from the bill slot  2   b ; a coin acceptor  25  for checking whether the coin inserted from the coin slot  2   a  is genuine; a ticket printer  26  for printing the exchange ticket; a hopper  27  for paying coins at the end of the game in the case of cash settlement; a counter  28  which counts the amount inserted into or paid out from the slot game machine  1  for the game machine administrator; ornamental lamps  29  for providing game effect light; among others.  
         [0085]    Further, the control unit  20  is also connected to structural elements  3 T of other buttons and the like via an interface  21   e.    
         [0086]    Moreover, the CPU  20   a  in the control unit  20  is connected to the liquid crystal display panel  5  via the image control circuit  20   d.    
         [0087]    The CPU  20   a  reads the image designs  6   an ″,  6   bn ″,  6   cn ″ and the image data of representation patterns and so on stored in the CD-ROM as the external storage device gm, creates an image signal thereby, and outputs such image signal to the image control circuit  20   d.    
         [0088]    In other words, by employing the image data of the image designs  6   an ″,  6   bn ″,  6   cn ″, created are an image signal of the reel peripheral face image  5   e   1  of the rotating or stopped image reel similar to the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  having the designs  6   an ,  6   bn ,  6   cn ; and an image signal of the image  5   e  employing the image data of the representation patter.  
         [0089]    Here, the reel peripheral face image  5   e   1  in rotation is created to be image-displayed at the same rotation angle speed as the rotation angle speed of the respective mechanical reels  6   a ,  6   b ,  6   c.    
         [0090]    The image control circuit  20   d  performs actual drawing processing, digital/analog conversion and the like by employing a RAM  20   e  as the graphic memory from the image signal input from the CPU  20   a , outputs this as an RGB signal to the liquid crystal display panel  5 , and this is displayed as an image on the liquid crystal display panel  5 .  
         [0091]    Next, the game display within the protective glass  1   g  in the slot game machine  1  is explained.  
         [0092]    For example, in the virtual image display mode, as shown in FIG. 6, the image Se is displayed at the upper half area of the liquid crystal display panel  5 , and a dark color is display all across the lower half area.  
         [0093]    Simultaneously, the illuminance of the reel lamp I ( 6   a   1 ), reel lamp  11  ( 6   b   1 ) and reel lamp III ( 6   c   1 ) is increased in the respective mechanical reels  6   a ,  6   b ,  6   c  in order to illuminate and conspicuously display the designs  6   an , . . . ,  6   bn , . . . ,  6   cn , . . . on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c , and reflects this on the half mirror  1   m  in order to display the virtual images  6   an ′,  6   bn ′,  6   cn ′ on the lower half area  1 Gs of the game display corresponding to the dark colored lower half area of the liquid crystal display panel  5 .  
         [0094]    In other words, the image  5   e  as the real image and the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  are displayed on the same game display  1 G.  
         [0095]    In this case, the player p visually recognizes the image  5   e  on the upper half area of the liquid crystal display panel  5  at the upper half area  1 Gu of the game display and visually recognizes the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the respective mechanical reels  6   a ,  6   b ,  6   c  at the lower half area  1 Gs of the game display through the protective glass  1   g.    
         [0096]    Here, the designs  6   an ,  6   bn ,  6   cn  of the respective mechanical reels  6   a ,  6   b ,  6   c  are illuminated brighter by the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) the illuminance of which has been increased, reflected by the half mirror  1   m , and clearly projected as the virtual images  6   an ′,  6   bn ′,  6   cn ′, and at the same time the lower half area of the liquid crystal display panel  5  that constitutes the background of the virtual images  6   an ′,  6   bn ′,  6   cn ′ is made of a dark color. As a result, the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the respective mechanical reels  6   a ,  6   b ,  6   c  are displayed clearly, and the player p will feel that he/she is visually recognizing the designs  6   an ,  6   bn ,  6   cn  of the actual mechanical reels  6   a ,  6   b ,  6   c.    
         [0097]    Next, as shown in FIG. 7, while displaying the image  5   e  on the upper half area of the liquid crystal display  5 , reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) within the mechanical reels  6   a ,  6   b ,  6   c  are turned off, and, in synchronization therewith, a reel peripheral face image  5   e   1  having the same visual recognition position as the image designs  6   an ″,  6   bn ″,  6   cn ″ which are the same as the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  is displayed at the lower half area of the liquid crystal display  5 . The image  5   e  and the reel peripheral face image  5   e   1  are displayed across the entire area of the game display within the protective glass  1   g  upon transferring the mode to the real image display mode.  
         [0098]    Here, it is difficult for the player p to notice that the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  visually recognized through the protective glass  1   g  in the virtual image display mode has been switched to the image designs  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  of the real image display mode displayed by the liquid crystal display  5 , and will visually recognize that the virtual images  6   an ′,  6   bn ′,  6   cn ′ to be identical with the image designs  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  instantaneously synchronized and switched.  
         [0099]    Therefore, by image-displaying a similar display of a virtual image of the mechanical reels  6   a ,  6   b ,  6   c  by employing the reel peripheral face image  5   e   1  displayed by the liquid crystal display  5 , it is possible to advance the game while transferring the virtual image display mode to the real image display mode in continuation without the player p hardly noticing.  
         [0100]    Contrarily, when transferring the real image display mode to the virtual image display mode, the routine is as follows.  
         [0101]    In the real image display mode (c.f. FIG. 7) in which the image  5   e  and the reel peripheral face image  5   e   1  are displayed with the liquid crystal display  5 , foremost, each of the mechanical reels  6   a ,  6   b ,  6   c  is rotated to a rotational position capable of displaying the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  identical to the image designs  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  as the virtual images  6   an ′,  6   bn ′,  6   cn ′.  
         [0102]    Then, in the liquid crystal display  5 , the reel peripheral face image  5   e   1  is non-displayed, a dark color is displayed thereto in synchronization, the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) within the mechanical reels  6   a ,  6   b ,  6   c  are turned off, the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  identical to the image designs  6   an ″,  6   bn ″,  6   cn ″ are illuminated, this is reflected on the half mirror lm so as to be displayed as the virtual images  6   an ′,  6   bn ′,  6   cn ′ at the visual recognition position identical to the image designs  6   an ″,  6   bn ″,  6   cn ″, and thereby transfers the mode to the virtual image display mode (c.f. FIG. 6).  
         [0103]    Here, it is difficult for the player p to notice that the image designs  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  displayed with the liquid crystal display  5  visually recognized through the protective glass 1 g in the real image display mode has been switched to the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c , and will visually recognize the image designs  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  to be identical with the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  instantaneously synchronized and switched.  
         [0104]    Therefore, by displaying a virtual image similar to the reel peripheral face image  5   e   1  display with the liquid crystal display  5  by employing the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c , it is possible to advance the game while transferring the real image display mode to the virtual image display mode in continuation without the player p hardly noticing.  
         [0105]    As described above, in the real image display mode, since the lower half area  1 Gs of the game display displayed to the player p is of a reel peripheral face image  5   e   1  displayed on the liquid crystal display  5 , it becomes possible to display an image as though the actual mechanical reels  6   a ,  6   b ,  6   c  deform limply or as though the actual mechanical reels  6   a ,  6   b ,  6   c  are blown to pieces by employing the reel peripheral face image  5   e   1 , thereby enabled is a game display impossible with the game machine structure in which the observer visually recognizes actual the mechanical reels  6   a ,  6   b ,  6   c.    
         [0106]    Meanwhile, in the virtual image display mode, since the designs  6   an ,  6   bn ,  6   cn  on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  are reflected on the half mirror lm and displayed to the player p as the virtual images  6   an ′,  6   bn ′,  6   cn ′ at the lower half area  1 Gs of the game display displayed to the player p, the mechanical reels  6   a ,  6   b ,  6   c  are visually recognized as in a game machine structured to directly view the actual mechanical reels, a realistic slot game can be displayed.  
         [0107]    Further, the mutual transfer between the game display modes similar to the case where the mechanical reel and image reel are stopped is also possible between the virtual image display mode in which the mechanical reels  6   a ,  6   b ,  6   c  are rotating and the real image display mode of the reel peripheral face image  5   e   1  in which the image reel is rotating.  
         [0108]    In this case, the image designs  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  are displayed to the player p having the same type and size of design as the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c , the displayed to the player p in the same order as the virtual image  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn.    
         [0109]    Moreover, the rotating reel peripheral face image  5   e   1  is structured to be displayed to the player p by moving the image designs  6   an ″,  6   bn ″,  6   cn ″ at the same rotation angle speed as the rotation angle speed of the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c.    
         [0110]    For instance, when there are  16  designs for each of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c , there are  16  image designs for each of the image designs  6   an ″,  6   bn ″,  6   cn ″ identical to the respective designs  6   an ,  6   bn ,  6   cn , and are displayed to the player p in the same order as the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn .  
         [0111]    Further, the rotating reel peripheral face image  5   e   1  is displayed to the player p by moving the  16  image designs  6   an ″,  6   bn ″,  6   cn ″ at the same rotation angle speed as the rotation angle speed of the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c.    
         [0112]    For example, in the virtual image display mode which displays the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the rotating mechanical reels  6   a ,  6   b ,  6   c , it is possible to transfer the mode to the real image display mode by displaying on the liquid crystal display  5  the reel peripheral face image  5   e   1  in which the image reel is rotating synchronously with the mechanical reel, in synchronization with the extinguishment of the reel lamp I ( 6   a   1 ), reel lamp U ( 6   b   1 ) and reel lamp III ( 6   c   1 ).  
         [0113]    Contrarily, when transferring the real image display mode to the virtual image display mode, in the real image display mode which displays on the liquid crystal display  5  the reel peripheral face image  5   e   1  in which the image reel is rotating, the reel peripheral face image  5   e   1  is non-displayed, a dark color is displayed thereto in synchronization, the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) are turned off, the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  rotating in synchronization with the image reel in advance identical are displayed, and thereby transfers the mode to the virtual image display mode.  
         [0114]    In the case of the rotating reel, also, it is possible to transfer the virtual image display mode to the real image display mode, or transfer the real image display mode to the virtual image display mode without the player p hardly noticing.  
         [0115]    Next, the transfer control from the virtual image display mode (c.f. FIG. 6) to the real image display mode in the slot game machine  1  is described (c.f FIG. 7).  
         [0116]    In the virtual image display mode shown in FIG. 6, the case of the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  being displayed, and the mechanical reels  6   a ,  6   b ,  6   c  are stopped is explained with reference to FIG. 8( a ).  
         [0117]    By the foregoing control program being executed, as shown in FIG. 6, the CPU  20   a  reads and acquires from the storage area of the RAM  20   c  the virtual image display design work data of the respective reels of a certain numerical value of 1 to 16 representing the design of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c , which is the real image of the virtual images  6   an ′,  6   bn ′,  6   cn ′ visually recognized by the player p when the mechanical reels  6   a ,  6   b ,  6   c  are stopped (step  1 ).  
         [0118]    Thereafter, the CPU  20   a  creates an image signal of the reel peripheral face image  5   e   1  having the image designs  6   an ″,  6   bn ″,  6   cn ″ of the identical design corresponding to the virtual image display design work data at a visual recognition position identical to the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  from the image data stored in the external storage device gm by employing the virtual image display work data acquired in (step  1 ), and outputs this to the image control circuit  20   d . (step  2 ).  
         [0119]    The image control circuit  20   d  creates image information of the reel peripheral face image  5   e   1  having the image designs  6   an ″,  6   bn ″,  6   cn ″ from the input image signal (step  3 ).  
         [0120]    The CPU  20   a  transmits the signal to the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ), and turns them off (step  4 ).  
         [0121]    While the CPU  20   a  transmits the signal to the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ), and turns them off (step  4 ), in synchronization therewith, the image control circuit  20   d  outputs the image information of the created reel peripheral face image  5   e   1  to the liquid crystal display panel  5 , and the liquid crystal display panel  5  displays the reel peripheral face image  5   e   1  having the image designs  6   an ″,  6   bn ″,  6   cn ″ on the lower half area 1 Gs of the game display (step  5 ).  
         [0122]    Meanwhile, in the virtual image display mode, the case of the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  being displayed, and the mechanical reels  6   a ,  6   b ,  6   c  are rotating is explained with reference to FIG. 8( b ).  
         [0123]    By the foregoing control program being executed, the CPU  20   a  reads and acquires the reel rotational position data stored in the storage area of the RAM  20   c  detected by the position sensor I ( 22   a ), position sensor II ( 22   b ) and position sensor III ( 22   c ) for detecting the rotation of the mechanical reels  6   a ,  6   b ,  6   c , and comprehends the respective rotational positions of the mechanical reels  6   a ,  6   b ,  6   c  (step  1 ).  
         [0124]    Next, the CPU  20   a  creates an image signal for displaying the reel peripheral face image  5   e   1  having the image designs  6   an ″,  6   bn ″,  6   cn ″ which rotate in synchronization with the same rotational position and rotational angle speed of the respective mechanical reels  6   a ,  6   b ,  6   c  comprehended at (step  1 ) upon employing the image data stored in the external storage device gm, and outputs this to the image control circuit  20   d  (step  2 ).  
         [0125]    The image control circuit  20   d  creates image information for displaying the reel peripheral face image  5   e   1  having the image designs  6   an ″,  6   bn ″,  6   cn ″ which rotate in synchronization with the same visual recognition position and rotational angle speed of the mechanical reels  6   a ,  6   b ,  6   c  from the input image signal (step  3 ).  
         [0126]    The CPU  20   a  transmits the signal to the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ), turns them off, and non-displays the virtual images  6   an ′,  6   bn ′,  6   cn ′ (step  4 ).  
         [0127]    While the CPU  20   a  transmits the signal to the reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ), and turns them off, in synchronization therewith, the image control circuit  20   d  outputs the image information for displaying the rotating reel peripheral face image  5   e   1  in synchronization at the same image design position and the identical rotational angle speed with the designs on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  to the liquid crystal display panel  5 , and the liquid crystal display panel S displays the rotating reel peripheral face image  5   e   1  on the lower half area  1 Gs of the game display (step  5 ).  
         [0128]    Next, the transfer control from the real image display mode (c.f. FIG. 7) to the virtual image display mode (c.f. FIG. 6) in the slot game machine  1  is described.  
         [0129]    In the real image display mode shown in FIG. 7, the case of the design images  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  being displayed, and the image reels are stopped is explained with reference to FIG. 9( a ).  
         [0130]    By the foregoing control program being executed, as shown in FIG. 7, the CPU  20   a  reads and acquires from the storage area of the RAM  20   c  the image display design work data of the respective image reels of a certain numerical value of 1 to 16 representing the design of the image designs  6   an ″,  6   bn ″,  6   cn ″ of the stopped reel peripheral face image  5   e   1  visually recognized by the player p, and specifies the design (step  1 ).  
         [0131]    Thereafter, the CPU  20   a  sends a signal to the stepping motor M 1 , stepping motor M 2  and stepping motor M 3  and respectively rotates the mechanical reels  6   a ,  6   b ,  6   c , and stops the respective reels at a rotational position such that the image designs  6   an ″,  6   bn ″,  6   cn ″ corresponding to the image display design work data and the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn , which are identical to the foregoing image designs, are displayed at the same visible recognition position (step  2 ).  
         [0132]    Then, the CPU  20   a  sends a signal to the image control circuit  20   d  and displays a dark color instead of the non-display of the reel peripheral face image  5   e   1  in the lower half area of the liquid crystal display panel  5  (step  3 ).  
         [0133]    While the CPU  20   a  displays a dark color in place of the non-display of the reel peripheral face image  5   e   1  and transmits the signal to the unlit reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ), and turns them on, it further illuminates and conspicuously displays the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c , reflects this on the half mirror  1   m , and displays the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  at the lower half area  1 Gs of the game display corresponding to the dark colored lower half area of the liquid crystal display panel  5  (c.f. FIG. 6) (step  4 ).  
         [0134]    Meanwhile, in the real image display mode, the case of the design images  6   an ″,  6   bn ″,  6   cn ″ of the reel peripheral face image  5   e   1  being displayed, and the image reels are rotating is explained with reference to FIG. 9( b ).  
         [0135]    By the foregoing control program being executed, the CPU  20   a  comprehends from the creation processing of the image signal the type and position of the respective image designs  6   an ″,  6   bn ″,  6   cn ″ rotating and displayed in the reel peripheral face image  5   e   1 .  
         [0136]    For example, it comprehends the type of each of such image designs  6   an ″,  6   bn ″,  6   cn ″ in a correct position against the player p (step  1 ).  
         [0137]    Next, the CPU  20   a  sends a signal to the stepping motor M 1 , stepping motor M 2  and stepping motor M 3  and rotates the mechanical reels  6   a ,  6   b ,  6   c  such that the designs  6   an ,  6   bn ,  6   cn  on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c , which have the same designs as each of the rotating image designs  6   an ″,  6   bn ″,  6   cn ″, rotate in synchronization therewith.  
         [0138]    In other words, in the reel peripheral face image  5   e   1 , the mechanical reels  6   a ,  6   b ,  6   c  are rotated in synchronization such that the virtual images  6   an ′,  6   bn ′,  6   cn ′, which has the same design as the respective designs  6   an ,  6   bn ,  6   cn  on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  displayed to the player p, rotate in the same visible recognition position, with respect to each of the rotating design images  6   an ″,  6   bn ″,  6   cn ″ displayed to the player p.  
         [0139]    For example, the type of each of such image designs  6   an ″,  6   bn ″,  6   cn ″ positioned to be displayed correctly to the player p at a certain timing is comprehended (step  1 ), and the mechanical reels  6   a ,  6   b ,  6   c  are rotates in synchronization such that the respective designs  6   an ,  6   bn ,  6   cn  on the peripheral face of the mechanical reels  6   a ,  6   b ,  6   c  having the same design are displayed as the virtual images  6   an ′,  6   bn ′,  6   cn ′ in a correct position to the player p at the same timing (step  2 ). Then, the CPU  20   a  transmits a signal to the image control unit  20   d  and non-displays the rotating reel peripheral face image  5   e   1  displayed on the lower half area of the liquid crystal display panel  5 , and instead displays a dark color (step  3 ).  
         [0140]    While the CPU  20   a  displays a dark color in place of the non-display of the reel peripheral face image  5   e   1  and transmits the signal to the unlit reel lamp I ( 6   a   1 ), reel lamp II ( 6   b   1 ) and reel lamp III ( 6   c   1 ) and turns them on, it further illuminates and conspicuously displays the designs  6   an ,  6   bn ,  6   cn  of the rotating mechanical reels  6   a ,  6   b ,  6   c , reflects this on the half mirror lm, and displays the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the rotating designs  6   an ,  6   bn ,  6   cn  at the lower half area  1 Gs of the game display corresponding to the dark colored lower half area of the liquid crystal display panel  5  (step  4 ).  
         [0141]    Moreover, in the embodiments described above, as illustrated in FIG. 4, description was made on an example where the image  5   e  of the liquid crystal display panel  5  is displayed on the upper half area  1 Gu of the game display to be visually recognized by the player p and the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  are displayed on the lower half area  1 Gs as the virtual images  6   an ′,  6   bn ′,  6   cn ′ reflected on the half mirror  1   m . However, in addition to this game display arrangement, for instance, the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  may be displayed on the upper half area  1 Gu as the virtual images  6   an ′,  6   bn ′,  6   cn ′ reflected on the half mirror lm and the image  5   e  of the liquid crystal display panel  5  is displayed on the lower half area  1 Gs, or the game display area may be divided into an upper area, center area and lower area, such that the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  are displayed at the center area of the game display as the virtual images  6   an ′,  6   bn ′,  6   cn ′ upon being reflected on the half mirror  1   m , and the image  5   e  of the liquid crystal display panel  5  may be displayed on the upper area and lower area. The arrangement of the virtual images  6   an ′,  6   bn ′,  6   cn ′ of the designs  6   an ,  6   bn ,  6   cn  of the mechanical reels  6   a ,  6   b ,  6   c  and the image  5   e  of the liquid crystal display panel  5  may be suitably and arbitrarily selected.  
         [0142]    According to the foregoing structure, in the game display area visually recognized through the protective glass, it is possible to play a slot game having the same realism as a game machine display actual mechanical reels since the mechanical reels are disposed inside the top box positioned above the game display unit, reflecting the designs of the mechanical reel peripheral face on the half mirror and displaying this as a virtual image.  
         [0143]    Moreover, since the game display is started from the display of design the mechanical reel peripheral face as a virtual image by reflecting the same on a half mirror, and then images of the image design of the image reel peripheral face identical to the virtual image of the design of the mechanical reel peripheral face is displayed to the same visual recognition position by means of a liquid crystal display panel, in synchronization with extinguishing the reel lamps to stop the illumination to the designs on the mechanical reel peripheral face and thereby ending the display of the virtual image, it is possible to proceed the game while smoothly transferring the virtual image display mode which displays a virtual image of the design of the mechanical reel peripheral face to the real image display mode which displays the image design of the image reel peripheral face without the player p noticing such transfer.  
         [0144]    Therefore, by transferring the virtual image display having a fantasy employing the virtual image of the design of the actual mechanical reel peripheral face to the real image display mode which displays the image design of the image reel peripheral face, in the real image display mode, it becomes possible to display an image as though the actual mechanical reels deform limply or as though the actual mechanical reels are blown to pieces.  
         [0145]    Thus, enabled is a game display employing changes in the mode of the mechanical reels, which was impossible with the game machine structure in which the observer visually recognizes actual the mechanical reels.  
         [0146]    Moreover, since a transfer is made from a real image display mode which displays the image designs on the liquid crystal display panel to a virtual image display mode in which the mechanical reels is rotated, the design on the peripheral face of the mechanical reels that are identical to the image designs displayed on the liquid crystal display panel are illuminated and displayed distinctly, in synchronization with ending the display of the image designs, and such displayed images are reflected by the half mirror to display the virtual images of the design, at the same visibly recognized position, it is possible to perform the transfer from the real image display mode which displays the image design on the peripheral face of the image reel to the virtual image display mode which displays virtual image of the design on the peripheral face of the mechanical reel so smoothly that such transfer is hardly recognized by the player p.  
         [0147]    Therefore, the transfer between the game display by a virtual image of a real item and the game display by an image becomes possible, and thereby realized is an image mutual transfer and succession method of a virtual image and a real image capable of realizing the successful combination of the reality of the real item and the fantasy of the real image, and enabling a rich representation.  
         [0148]    Further, although a slot game machine was exemplified in the foregoing embodiments, it goes without saying that the image mutual transfer and succession method according to the present invention may be effectively employed in displays of other game machines or displays of other equipment.
