  4 is a plan view of the card placement panel 7 as viewed from above, and FIG. 5 is a longitudinal sectional view of the housing 31 to which the card placement panel 7 is attached. As shown in FIGS. 4 and 5, the card placement panel 7 includes a transparent glass plate 33 attached so as to close the upper surface opening 32 of the housing 31, and a thin play field laminated on the upper surface of the glass plate 33. And a sheet 34 for use.

  The card 6 is placed on the upper surface of the play field sheet 34. And inside the housing | casing 31, the light source 35 which irradiates infrared rays (invisible light) to the back surface of the card | curd 6 mounted in the card | curd arrangement | positioning panel 7, and the visible light is removed from the light emitted from the light source 35. 1 filter 36, the 1st reflecting plate 37 which reflects the reflected light reflected on the back surface of the card | curd 6 upwards, and the 2nd reflecting plate 38 which reflects the reflected light (invisible light) reflected by the 1st reflecting plate 37 below.

Further, from the inside of the sealed casing 31, infrared light (invisible light) obtained by cutting visible light from the light source 35 is applied to the card arrangement panel 7. The inside of 31 cannot be peeped.

  FIG. 6 is a diagram showing an example of a code pattern provided on the card 6.

  In FIG. 6, a code pattern 170 composed of a plurality of patterns having different radii is printed on the back surface of the card 6. The code pattern 170 includes a card position detection circle 172, a position angle detection pattern area 174 formed on the outer periphery of the card position detection circle 172, an ID data area 176 formed outside the position angle detection pattern area 174, It has an annular white area 178 formed inside the card position detection circle 172, a data area 180 formed inside the annular white area 178, and a center point 182 formed inside the data area 180. The code pattern 170 is recognized by the density difference between the black portion 170a and the white portion 170b.

  Further, the code pattern 170 is printed using ink that transmits infrared rays, so that the player cannot directly see the code pattern 170. Therefore, it is possible to prevent the player or another person from crafting the code pattern 170 to modify the code pattern 170 or forging a card imitating the code pattern 170.

  In the code pattern 170, a card position detection circle 172, a position angle detection pattern area 174, an ID data area 176, an annular white area 178, and a data area 180 are concentric with a center point 182 as a center. The ID data area 176 having a radius larger than the short side of the card 6 is formed in a curved shape. That is, in the ID data area 176, a part of the outermost circular pattern located at a radius larger than the short side portion is recorded in an arc shape with respect to the rectangular card surface. The area can be used effectively.

  FIG. 7 is a diagram illustrating an example of an image obtained by capturing the back surface of the card 6 with the image sensor 40 (FIG. 5). As shown in FIG. 7, when the code pattern 170 is imaged by the image sensor 40, the black and white part is recognized as “1” and the black and white part is recognized as “0”. White portions of the ID data area 176 and the data area 180 are hatched portions, but predetermined information is displayed in combination with black portions, not blanks. That is, the black portion and the white portion are extracted as a 1-bit signal, and the arrangement pattern of the black portion and the white portion differs according to the content of predetermined information. The arrangement pattern with the white portion functions as a code pattern. In this example, the size is determined so that each half bit (one black portion or white portion) is 6 dots on the screen where the image data captured by the image sensor 40 is captured.

  In this example, the code position (center position) detection from the code pattern 170 of the card 6 is detected by the luminance difference between the inside and the outside of the card position detection circle 172. For this reason, a white region is formed in an annular shape inside and outside the card position detection circle 172, whereby the difference in luminance between the inner periphery and the outer periphery is clarified in the card position detection circle 172. Since the card position detection circle 172 is a circle, the position can be detected regardless of the orientation (position angle) of the card 6.

  Further, for detecting the position angle (the direction of the card 6) of the code pattern 170, the circumferential interval between the protrusions 174a to 174d of the position angle detection pattern region 174 protruding radially outward from the outer periphery of the card position detection circle 172 Is detected and determined. Therefore, the circumferential intervals of the protrusions 174a to 174d are not equal intervals, and the intervals are different so that the position angle of the card 6 is determined by detecting the intervals.

  The value of each bit is determined by the luminance difference between two adjacent half-bit areas. When determining the brightness of each area, the brightness at the center of each area is extracted without using the marginal area in order to reduce the influence of blurring and errors at the time of position / angle detection.

  As shown in FIG. 8, the bit start positions S <b> 1 to S <b> 4 of the ID data area 176 and the data area 180 are different for each card 6.

  As shown in FIG. 9, 16-bit information consisting of pattern data 0 to 15 is obtained in the ID data area 176 and the data area 180. Each of the pattern data 0 to 15 is composed of the black portion and the white portion, and one of the black portion and the white portion is provided for easy identification from the image data captured by the image sensor 40 (FIG. 5). The area is set to be large, and erroneous recognition of data is prevented.

  The card position coordinate detection process is performed as follows. First, when the card 6 is placed on the card placement panel 7 (FIG. 5), the position coordinates of the card 6 are detected. Here, by detecting the card position detection circle 172 formed of a circular code pattern for detecting the position coordinates, the position coordinates can be detected at high speed without being affected by the position angle of the card 6.

  Therefore, in the card position coordinate detection process, the luminance difference between the black portion of the card position detection circle 172 and the white areas formed inside and outside the code pattern 170 shown in FIGS. 7 to 9 is measured by pattern matching. Thus, the position of the card 6 is detected.

  In the card position coordinate detection method, as shown in FIGS. 10A to 10D, since the position of the card position detection circle 172 is the position of the card 6, the image captured by the image sensor 40 (FIG. 5). The position of the card 6 is recognized by detecting the position of the card position detection circle 172 from the data.

  As shown in FIG. 10A, the inner side of the card position detection circle 172 is divided into 12 regions R1 to R12 for evaluation. Two pairs of points indicated by white points 182 and black points 184 are set in each of the divided regions R1 to R12. At these two pairs of points, the white point 182 is positive and the black point 184 is negative, and the respective luminances are added to obtain evaluation values for the regions R1 to R12.

  FIG. 10B shows an arrangement pattern of white spots 182 and black spots 184 with the inner periphery of the card position detection circle 172 as a boundary. Based on the arrangement pattern of the white point 182 and the black point 184, the inner peripheral contour data is evaluated using the inner peripheral edge of the card position detection circle 172 and the card position detection circle 172 and the inner region 186 thereof. As a result, a rough coordinate position of the position where the card 6 is placed is recognized. The hatched portion representing the card position detection circle 172 has an evaluation value of 0. Further, the coordinates where all the evaluation values of the 12 areas divided as described above exceed the set threshold A, and 10 of them (which can be changed by setting) exceed the threshold B are stored as candidate card coordinates. . At this time, the sum of the evaluation values of all the areas is stored as the evaluation value N of the coordinates.

  Next, the card coordinates stored as card coordinate candidates are evaluated using a 12-division pattern 188 shown in FIG. The 12-divided pattern 188 is evaluated using the outer periphery of the card position detection circle 172 and its outer region. FIG. 53D shows an arrangement pattern of white spots 190 and black spots 192 with the outer periphery of the card position detection circle 172 as a boundary. Based on the arrangement pattern of the white point 190 and the black point 192, the outer periphery of the card position detection circle 172 is used as the outer periphery using the white region of the card position detection circle 172 and the position angle detection pattern region 174 formed outside the card position detection circle 172. Evaluate contour data. Thereby, the exact coordinate position of the position where the card | curd 6 was mounted is recognized.

  Four pairs of points indicated by a white point 190 and a black point 192 are set in each of the regions R1 to R12 divided into 12 as described above. At this point, the white point 190 is positive and the black point 192 is negative, and the respective luminances are added, and the added value is used as the evaluation value for each of the regions R1 to R12. The hatched part is 0. Then, the coordinates at which all the evaluation values of each of the regions R1 to R12 exceed the set threshold C and nine of them (which can be changed by setting) exceed the threshold D are stored as candidate card coordinates. At this time, the sum of the evaluation values of all the regions R1 to R12 is stored as the evaluation value M of the coordinates. The sum of the evaluation value N and the evaluation value M is defined as the evaluation value Σ of the coordinates.

  When all the coordinates have been evaluated or the number of candidate coordinates exceeds the set number, thinning is performed by deleting coordinates with small evaluation values for a plurality of candidate coordinates at a distance equal to or less than the value set as the thinning distance. The coordinates with the large evaluation value remaining after the thinning are used as the coordinate position of the card 6.

  Next, card angle detection processing performed after card position detection will be described with reference to FIGS. 11 and 12A to 12C. As shown in FIG. 11, in the card angle detection process, angle detection is performed on the coordinates where the card position is detected. As this angle detection method, discrimination is made by detecting the circumferential interval of the protrusions 174a to 174d of the position angle detection pattern region 174 (indicated by hatching in FIG. 11) that protrudes radially from the outer periphery of the card position detection circle 172. To do. As described above, since the coordinates for performing the angle detection process are narrowed down by the position detection, the processing time is shortened compared with the process for all the coordinates.

  The position angle (orientation) of the card 6 placed on the card arrangement panel 7 (FIG. 5) is determined by the intervals L1 to L4 in the circumferential direction of the protrusions 174a to 174d protruding on the outer periphery of the position angle detection pattern region 174. The intervals are set in advance, and the intervals L1 to L4 are arranged at different intervals so that L1 <L2 <L3 <L4. Therefore, the position of the card 6 can be determined from the detection pulse time interval by scanning the detection positions of the protrusions 174a to 174d.

  In this example, the angle detection is performed by pattern matching by comparing the pattern of the detection pulse of each of the protrusions 174a to 174d with a previously stored pattern. For example, if the width (circumferential dimension) of the protrusions 174a to 174d for angle detection is 1, the ratio of the intervals L1: L2: L3: L4 of the protrusions 174a to 174d is 3: 4: 5: 8. It is arranged to become. Thus, misrecognition of angle detection is prevented by changing the ratio of the intervals L1 to L4.

  Instead of changing the ratio of the intervals L1 to L4 of the protrusions 174a to 174d, the widths (circumferential dimensions) of the protrusions 174a to 174d may be changed to be different dimensions. In addition, the position angle detection pattern region 174 is made as small as possible to the width of the card 6 as much as possible to reduce the detection error.

  As shown in FIGS. 12A to 12C, in the method of detecting the protrusions 174a to 174d, the density difference (brightness difference) between the protrusions 174a to 174d and the white of the position angle detection pattern region 174 with respect to the white color. ) To detect the edges (side edges), and the intervals on the time axis of the detection signals are the intervals L1 to L4. Further, when the edge of each of the protrusions 174a to 174d is detected, an edge detection signal for switching from white to black rises to the + side, and an edge detection signal for switching from black to white falls to the-side. Therefore, the interval L between the negative detection signal and the next positive detection signal coincides with any one of the intervals L1 to L4 of the protrusions 174a to 174d.

  In this example, the brightness data Y [n] (at the time of angle n) is extracted from the position angle detection pattern region 174 in increments of 1 ° from the angle 0 ° to 359 °, and Edge [n] = V [n−1] −V Extract edge values at [n + 1]. Note that, in the card arrangement panel 7 (FIG. 5), the upper front direction as viewed from the player is set to a reference angle of 0 °.

  Then, a total value obtained by multiplying the filter signal (registered in advance) shown in FIG. 12A by the circumferential edge detection signals of the protrusions 174a to 174d shown in FIG. Seek by shifting one by one. When the filter signal matches the edge detection signal at an arbitrary angle, the total value becomes maximum. For this reason, the position where the total value shown in FIG. Accordingly, it is determined that the card 6 placed on the card placement panel 7 (FIG. 5) is oriented in the clockwise direction by an angle θ with respect to the reference angle (0 °).

  If the illumination with respect to the card 6 is not uniform, the interval between the white portions may have a lower detection level than the interval between the black portions, and may not be distinguished from noise. On the other hand, in this example, as described above, the evaluation is performed based on the detection value of the circumferential edge of each of the protrusions 174a to 174d. Since the protrusions 174a to 174d can be accurately detected by performing the relative processing as uniform, the position angle can be detected more accurately.

  Next, an ID decoding process for reading the ID data area 176 and the data area 180 will be described. If the position coordinates and the position angle of the card 6 are known as described above, the bit positions formed in the ID data area 176 and the data area 180 are uniquely determined, so that the discrimination process can be performed accurately without erroneous recognition. . Further, in this example, it is only necessary to decode the detected position coordinates of the card 6, so that the card information can be read in a short time.

  As shown in FIGS. 6 to 9 described above, the code patterns formed in the ID data area 176 and the data area 180 are each composed of about 6 dots × 6 dots (black portion 170a and white portion 170b). The half-bit area (black portion 170a or white portion 170b) is all white or black. In adjacent code pattern areas, a combination of the black portion 170a and the white portion 170b always constitutes one bit. As a result, even if the absolute value of luminance cannot be determined due to light unevenness of illumination or the like, each bit of the code pattern can be determined by the luminance difference of the relative value.

  As shown in FIG. 9, 4-bit code patterns 0 to 3 are arranged in the data area 180 arranged inside the card position detection circle 172, and these arranged positions are represented by the above-described positions. Thus, the evaluation value of each half-bit area is obtained by calculating from the detected card position coordinates and position angle. The evaluation value in this case is the sum of a plurality of dots in the data area 180 displayed at the card position in the image captured by the image sensor 40 (FIG. 5). Thus, by setting the evaluation value as the sum of a plurality of dots, even if there are missing dots or noise, the influence can be reduced. If one dot can be evaluated accurately, the value for one dot may be used as the evaluation value.

  At this time, the boundary portion of the data area 180 is not used because it may hinder the calculation of an accurate evaluation value due to an error at the time of position coordinate and angle detection, a defocus at the time of photographing, or the like.

  Similarly, 12-bit code patterns 4 to 15 are arranged in the ID data area 176 arranged outside the card position detection circle 172, and the evaluation values of the code patterns 4 to 15 are also obtained. Each bit of the stored card data is obtained. At this time, if the difference between the evaluation value of the white portion and the black portion of each bit exceeds the threshold value E, it is registered as an appropriate code if it exceeds the set number, and if it exceeds the set number, it is registered as an illegal code. delete.

  In addition, a parity (error detection code) bit is set, and a code in which a parity error has occurred is also deleted as an illegal code. Then, the bit array recognized as a correct value is decoded according to an ID decoding table (not shown) to obtain the ID data of the card 6. In this example, the most significant 2 bits of the 16 bits are parity bits, the parity is calculated, and if there is an error, it is deleted as an illegal code.

  Next, the configuration and operation of software in the terminal devices 4a to 4h illustrated in FIGS. 1 to 3 will be described.

  FIG. 13 is a diagram showing an example of a functional block configuration of hardware and software of a card game device to which the present invention is applied.

  When the unit corresponding to the card selected and determined by the card selection determining unit 65 of the unit control unit 61 is in a state where the unit can use the scheme (when morale is accumulated at a predetermined level), the scheme control unit 66 A target selection processing unit 67 that displays a target of the strategy according to the angle of the target and causes the player to select, an effect range determination processing unit 68 that determines the effect range of the strategy, and a situation of damage to the enemy side by executing the strategy The execution execution part 69 which reproduces these.

  The screen control unit 70 includes a title / advertisement screen control unit 71 that controls display of the game title and advertisement at the start of the game, a mode selection screen, a card registration screen, a military method selection screen, and a continental display screen that matches opponents. , Battle result screen, preparation screen control unit 72 for controlling display of preparation screen such as promotion / demotion screen according to battle result, subjugation screen, and display of battle preparation screen such as opponent introduction screen, card placement screen, etc. The battle preparation screen control unit 73 that performs control, the battle screen control unit 74 that performs display control of the battle screen, and the result announcement that performs display control of an experience value acquisition screen, a card discharge screen, a battle result browsing screen, and the like according to the battle result And a screen control unit 75.

  FIG. 14 is a flowchart showing screen transition of the card game apparatus to which the present invention is applied. These processes are mainly performed by the game application 58 shown in FIG.

  In FIG. 14, a title and advertisement screen is displayed at the start of the game (step S101), and then a mode selection screen (step S102), a card registration screen (step S103), and a military method selection screen (step S104) as preparation screens. The continent display (matching) screen (step S105) is sequentially displayed.

  Next, an opponent introduction screen (step S106) and a card arrangement screen (step S107) are displayed as battle preparation screens. Fig. 15 shows an example of the card placement screen. Corresponds to the position of the placed card in the image with the castle on your side in the foreground (bottom of the screen) and the castle on the enemy side in the front (upper screen). Then, the outline image 81 of the unit and the caption 82 including its icon, name, characteristic value, and the like are displayed.

  Returning to FIG. 14, following the display of the card arrangement screen, the battle screen is displayed (step S108). FIG. 16 is a diagram showing an example of the battle screen. The main screen 83 displays an image in which the battle situation is zoomed in, including a caption 82 indicating a unit corresponding to the card and an image of a soldier of the unit. The screen 84 displays the arrangement of each card (unit) in the entire battle area. When the battle screen is displayed, a voice (BGM) that conveys the atmosphere of the battle is played for each stage.

  Returning to FIG. 14, after the battle is over, a battle result screen (step S109) and a rank promotion or demotion screen (step S110) are displayed as a preparation screen. Furthermore, if it is 3 consecutive wins, a subjugation screen directing the success of subjugation is displayed (steps S111 and S112). If it is a win other than 3 consecutive wins, a subjugation screen directing destruction of the enemy castle is displayed (steps S113 and S114). Subsequently, a screen (step S115) for prompting a challenge to the consecutive win bonus is displayed. Here, when the player challenges the consecutive win bonus, the screen shifts to a continental display (matching) screen (steps S116 and S105).

  When the player does not challenge the winning streak bonus, when the player makes a streak of 3 consecutive wins, or when the player loses a battle, an experience value acquisition screen (step S117), a card discharge screen (step S118), and a battle record are displayed as a result announcement screen. The browsing screen (step S119) is sequentially displayed, and when the game is continued (continue), the mode selection screen (step S102) is shifted to. When the game is not continued, the game is over (step S120).

  Next, the process of changing the state of a unit depending on the card angle during the battle will be described.

  FIG. 17 is a flowchart showing a unit state change process according to the card angle. These processes are mainly performed by the case 51, the game base 54, the basic program 55, the card information analysis processing unit 59, and the unit control unit 61 shown in FIG.

  In FIG. 17, card information including a card ID, card coordinates, and card angle is read (step S201) and the card information is serially transmitted to the application side (step S202).

  On the application side, card information is serially received (step S203), card ID analysis (step S204), card coordinate analysis (step S205), and card angle analysis (step S206) are sequentially performed.

  Next, the card orientation is determined from the card angle (step S207). If the card is in portrait orientation, state change processing corresponding to portrait orientation is performed (step S208). If the card is in landscape orientation, state change corresponding to landscape orientation is performed. Processing is performed (step S209). For example, depending on whether the orientation is vertical or horizontal, the type (type) of the card unit is changed, or other parameters of the card unit are changed. Here, when changing the type or parameter of a card unit, a plurality of parameters previously associated with the rotation angle of the card are stored in the memory as parameters of one unit that is a game target represented by each card. The parameters are changed by selecting a parameter according to the angle from these parameters. Then, the state after the state change process is displayed on the screen (step S210).

  FIG. 18 is a diagram showing an example of the change in the state of the unit depending on the card angle. When the card 6 is in the horizontal direction as shown in FIG. When the parameter is “3” and the card 6 is vertically oriented as shown in (B), the military type is the bow unit, the attack parameter is “10”, and the range parameter is “10”.

  Next, the effect determination process of the strategy by the card angle during the battle will be described.

  FIG. 19 is a flowchart showing the effect determination process of the strategy based on the card angle. These processes are the case 51, case 52, game base 54, basic program 55, basic program 56, card information analysis processing unit 59, button analysis processing unit 60, unit control unit 61, and schematic control unit shown in FIG. 66 mainly.

  In FIG. 19, as the case side processing, card information including a card ID, card coordinates, and card angle is read (step S301), and the card information is serially transmitted to the application side (step S302).

  On the application side, card information is serially received (step S303), card ID analysis (step S304), card coordinate analysis (step S305), and card angle analysis (step S306) are sequentially performed.

  Next, it is determined whether the card angle matches the target of the attack (enemy unit, etc.) (step S307). If the angle matches the target, it is determined whether there is a button input for the approximate activation (step S308). In the case where there is, the process of activating the effect of the strategy (the effect of damaging the enemy side, effects such as sound) is entered (step S309), and the screen is displayed (step S310). If the angle is not the target (NO in step S307) and there is no button input (no step S308), the effect activation process (step S309) is not performed, and the screen display (step S310) is performed.

  FIG. 20 is a diagram showing an example of a screen showing the effect range of the scheme. The main screen 83 clearly shows the unit arrangement 85 on the side that activates the scheme, and the sub screen 84 clearly shows the effect range 86. It can be easily understood that the attack targets 87 and 88 are included in the effect range. Here, since a fire meter is assumed as a strategy, the effect range 86 is a rectangle that has a linear effect. FIG. 21 shows an example in which the effect range 86 deviates from the objects 87, 88, 89 and the like because the card angle is directed right above.

  FIG. 22 is a diagram showing another example of the screen showing the effect range of the scheme. Since the lightning strike is assumed as the scheme, the effect range 86 is a circular shape having a radial effect around a predetermined point. This indicates that the objects 90, 91, and 92 are included in the effect range 86. FIG. 23 shows an example in which the effect range 86 deviates from the objects 90, 91, 92, etc. due to the inclination of the card angle.

  Next, the screen display control process at the time of card movement during battle will be described.

  24 and 25 are flowcharts showing the screen display control process when the card is moved. These processes are mainly performed by the case 51, the game base 54, the basic program 55, the card information analysis processing unit 59, the unit control unit 61, and the screen control unit 70 shown in FIG.

  In FIG. 24, as the initial position display processing, the card position (coordinate / angle) is first detected (step S401), and the position of the unit in the virtual three-dimensional space on the game is calculated from the detected card position (step S402). ), And display the card-shaped display body and the unit image at the calculated position (step S403). FIG. 26A shows an example of a screen on which the initial position is displayed, and the display body 94 and the display body 94 on the display screen 93 correspond to the position where the card 6 is placed on the card placement panel 7. Unit 95 is displayed.

  Subsequently, returning to FIG. 24, the card position is detected, and it is determined whether or not there is any movement / rotation (step S404). If it is determined that there has been movement / rotation, the position of the unit in the virtual three-dimensional space on the game is calculated from the detected card position (step S405), and the card-shaped display body 94 at the original position is deleted. The display body 94 is displayed at the calculated new position (step S406). At this time, the display body 94 may be rotated in accordance with the orientation of the display card 94 according to the arrangement angle of the destination card. FIG. 26B shows an example of the screen in this state. When the card 6 is moved to the position shown in the figure on the card placement panel 7, the display of the unit 95 is shown on the display screen 93. As it is, only the display body 94 is displayed at a new position. As a result, the position and angle at which the card has been changed can be immediately recognized on the screen by moving and displaying only the display body 94 first, and the position and angle of the card can be finely adjusted. .

  Next, returning to FIG. 24, the movement parameter of the unit (parameter indicating the movement speed according to the type of the unit) is read from the memory (step S407), and the current position (original position) and the calculated new position are used. The moving direction is calculated (step S408).

  Subsequently, in FIG. 25, the unit is rotated and displayed by a predetermined angle in the moving direction (step S409), and the unit is moved and displayed at the moving speed based on the moving parameter toward the calculated position (step S410). Next, it is determined whether or not the rotation is completed with respect to the moving direction (step S411). If it is not completed, it is determined whether or not the current position and the position of the moving destination have become a predetermined distance ( In step S412), if the predetermined distance is not reached, the unit returns to the rotation display (step S409). Further, when the rotation is completed, it is determined whether the current position and the position of the moving destination have become a predetermined distance (step S413). Through these processes, the unit moves while gradually changing the angle toward the destination. Further, when the enemy unit is contacted during the movement, the battle is performed according to the parameter of the unit 95 corresponding to the state where the angle is changed, and the battle result is determined. FIG. 26 (b) shows a state in which the unit 95 has started to move, and FIG. 27 (c) shows a state in which the unit 95 has approached the destination to some extent. It should be noted that the predetermined distance in steps S412 and S413 is such that the unit 95 is rotated while moving in the direction in which the card has moved, and this time the unit 95 matches the arrangement angle with respect to the arrangement surface of the arranged card. In order to rotate while moving 95, it is the distance which specified the point which switches a rotation direction when a rotation direction does not correspond. This distance may be a predetermined distance or may be calculated from the direction (direction) in which the card moves even if it is calculated from the angle formed by the direction of the card before the movement and the direction in which the card is arranged and the movement distance. It is also possible to calculate a moving distance required until the rotation is completed in the direction in which the card is arranged to obtain a predetermined distance.

  Returning to FIG. 25, when the current position and the position of the movement destination are a predetermined distance (YES in steps S412 and S413), the direction of the unit is rotated and displayed by a predetermined angle based on the rotation angle of the arranged card ( In step S414, the unit is moved and displayed at the moving speed based on the moving parameter toward the calculated position (step S415). Next, it is determined whether or not the current position and the destination position are the same (step S416). If they are not the same, it is determined whether or not the rotation is completed (step S417), and the rotation is completed. If not, the process returns to the unit rotation display (step S414), and if the rotation has been completed, the process returns to the unit movement display (step S415).

  If the current position and the destination position are the same (YES in step S416), it is determined whether or not the rotation has been completed (step S418). Based on the rotation angle of the card, the direction of the unit is rotated and displayed by a predetermined angle (step S419), this is repeated until the rotation is completed, and the process is terminated when the rotation is completed. FIG. 27D shows a state in which the unit 95 has reached the area of the display body 94 that is the movement destination, and the unit 95 has changed its direction from the previous traveling direction to the head direction of the display body 94. ing. If the card 6 is further moved thereafter, the same processing is performed from step S404 in FIG.
