Each of the section detection sections 1801 to 1882 of the detection section 18 outputs a section detection signal to the conversion rule determination section 19 or the conversion section 20 when the corresponding section members 1101 to 1182 are pushed. The conversion rule determination unit 19 determines a conversion rule for converting the segment detection signal of the input conversion unit 20 based on the segment detection signal input from the detection unit 18. The conversion unit 20 converts the segment detection signal input from the detection unit 18 in accordance with the conversion rule determined by the conversion rule determination unit 19.

The transmission unit 22 transmits the segment detection signal converted by the conversion unit 20 to the dart game advancing device 50.

The operation input unit 21 detects a user's operation (pressing a button), and outputs a detection signal to the conversion rule determination unit 19 and the transmission unit 22. The operation input unit 21 outputs a reset signal to the conversion rule determination unit 19 and the transmission unit 22 in response to a user's reset operation (pressing the PREV button 14 at a predetermined timing).

The receiving section 51 of the dart game advancing device 50 receives the segment detection signal and the reset signal transmitted from the transmitting section 22 of the dart board device 10. As described above, since the transmitting unit 22 transmits a signal in accordance with the Bluetooth (registered trademark) standard, the receiving unit 51 also receives the signal in a manner conforming to the standard.

The inverse transformation rule determination unit 52 determines, based on the password generated by the password generation unit 54, to use the segment detection signal received by the reception unit 51 to advance the segment detection signal. Inverse transformation rules for inverse transformation. This inverse conversion rule corresponds to a conversion rule determined by the conversion rule determination unit 19 and is a rule for performing an inverse conversion of the conversion rule determined by the conversion rule determination unit 19. That is, the original signal is restored by converting the signal converted by the conversion rule according to the inverse conversion rule.

The inverse transform unit 53 inversely transforms the segment detection signal received by the receiving unit 51 according to the inverse transform rule determined by the inverse transform rule determining unit 52. The password generation unit 54 randomly generates a password. In this embodiment, the password is composed of four digits, and each digit is any of 1 to 20. The password generation unit 54 generates a password when the dart game advancing device 50 is first used with the dart board device 10. The password generation unit 54 of this embodiment updates the password. When the password generation unit 54 generates a new password, the conversion rule determination unit 19 updates the conversion rule using the new password, and the inverse conversion rule determination unit 52 updates the inverse conversion rule using the new password. The time when the password is updated by the password generation unit 54, the conversion rule is updated by the conversion rule determination unit 19, and the inverse conversion rule is updated by the inverse conversion rule determination unit 52 will be described later.

The dart game advancing apparatus 50 may not include the password generating unit 54. In this case, a unique password is stored for each dart game advancing device 50, and the user operates the operation input unit 57 so that the fixed password is displayed on the display unit 56. In addition, the term “fixed password” means that the inverse transformation rule determined based on the determination is also fixed. In this case, the inverse transformation rule determination unit 52 is not required. In this case, the inverse transform unit 53 uses the generated inverse transform based on a predetermined fixed password. The rule performs the inverse transformation of the segment detection signal.

The game advancement processing unit 55 performs processing necessary to select and start advancement of a game such as a game. When the game starts, the game advancement processing unit 55 performs a segment detection signal that has been inversely transformed (decrypted) based on the inverse transforming unit 53 using the inverse transforming rule determined by the inverse transforming rule determining unit 52, and plays the game according to a predetermined dart game rule.

As the game progresses, the display unit 56 displays a screen that guides the progress of the game, a performance screen, a screen for selecting and starting the game, and the like. In addition, as shown in FIG. 1, the dart board device 10 is also provided with a display 12. However, the display 12 is small and not capable of displaying an arbitrary image, and is a simple display. Therefore, it is preferable to use the display portion 56 of the dart game advancement device 50 composed of a smartphone, a desktop PC, a notebook PC, or the like, which is a general-purpose device, to guide the progress of the game including a more attractive performance. The same is true of the implementation. In other words, the dart game advancing device 50 and the dart board device 10 are separately provided, and one of the purposes of using the general purpose computer for the dart game advancing device 50 is to use such a high-definition display portion 56. The display section 56 may be a liquid crystal display panel.

Next, a method of determining a conversion rule and an inverse conversion rule in the dart game system 100 configured as described above will be described. In the dart game system 100 of the present embodiment, the conversion rule determination unit 19 and the inverse conversion rule determination unit 52 use the same password to determine the conversion rule and the inverse conversion rule, respectively. The transformation rule and the inverse transformation rule correspond to each other, that is, when the section detection signal transformed by the transformation rule is inverted according to the inverse transformation rule When changing, the original segment detection signal is restored.

8 is a flowchart of a process of determining a conversion rule and an inverse conversion rule according to the embodiment of the present invention. First, in the dart game advancing apparatus 50, the password generation unit 54 randomly generates a password composed of four digits using random numbers (step S81). In the example of FIG. 8, the four numbers are represented by “a”, “b”, “c”, and “d”. When the password is generated, the display unit 56 designates the password by displaying the password as recognizable by the user (step S82).

The inverse transformation rule determination unit 52 stores an inverse transformation rule x = y / A. Here, x represents a segment detection signal before conversion, and y represents a segment detection signal after conversion. A is a coefficient parameter defined by a + b + c + d. When the inverse transformation rule determination unit 52 generates the passwords "a", "b", "c", and "d" by the password generation unit 54, it inputs them, calculates a + b + c + d, substitutes them into A, and decides Inverse transformation rules (step S83).

The user recognizes a password composed of four digits designated through the display portion 56 of the dart game advancing device 50 (step S84), and inputs the password to the dart board device 10 (step S85). At this time, the user pushes down the section members 1101 to 1182 corresponding to the password of the disk 11, and the detection section 18 determines the content of the pushed section, and inputs the password into the dart board device 10. The detection unit 18 detects that the segment members 1101 to 1182 are sequentially pushed down, and sequentially outputs the corresponding segment detection signals to the conversion rule determination unit 19 (step S86).

At this time, in order to confirm the segment detection signal detected by the detection section 18, the section detection signal may be transmitted from the transmission section 22 to the dart game advancing device 50 without conversion. In this case, the dart game advances The device 50 receives the segment detection signal from the receiving unit 51 and displays it on the display unit 56. Specifically, when the four digits that have been displayed on the display section 56 coincide with the content of the segment detection signal, the color of its serial number is changed. When the next digit to be input does not match the content of the segment detection signal, the display unit 56 may display an error.

The conversion rule determination unit 19 determines the conversion rule when the segment detection signal is input from the detection unit 18 to obtain the password information (step S87). Specifically, the conversion rule determination unit 19 stores a conversion rule y = Ax. Here, x represents the segment detection signal before the conversion, and y represents the segment detection signal after the conversion. A is a coefficient parameter defined by a + b + c + d, as in the case of determining the inverse transformation rule. When the conversion rule determination unit 19 inputs passwords "a", "b", "c", and "d" based on the segment detection signal, it calculates a + b + c + d and substitutes A to determine the conversion rule.

In addition, as described above, the content of the segment includes the magnification and the score, but the conversion rule determination unit 19 determines the conversion rule based only on the information of the score in the segment detection signal. That is, the user can push down any one of the single, double, and triple of the specified score when entering the password.

As described above, the conversion rule determination unit 19 determines a conversion rule of y = (a + b + c + d) x, and the inverse conversion rule determination unit 52 determines a section to be transformed according to the conversion rule. Detects the inverse transform rule of x = y / (a + b + c + d) for signal recovery.

Next, the process of transforming and inversely transforming the segment detection signal using the transform rules and inverse transform rules determined as described above will be described. Figure 9 is a flowchart of a process of converting a segment detection signal under a transform rule and an inverse transform rule according to the embodiment of the present invention. When the dart game is started and the dart is thrown on the disk 11 and acts on a certain zone (step S91), the corresponding zone detection units 1101 to 1182 of the detection unit 18 output the hit zone to the conversion unit 20 The segment detection signal x of the segment (step S92).

The transform unit 20 transforms the segment detection signal x using a transform rule y = (a + b + c + d) x (using a transform function f (x) = (a + b + c + d) x) to generate a transformed region Segment detection signal y (step S93). The transmitting unit 22 transmits the converted segment detection signal y toward the dart game advancing device 50 (step S94). The receiving unit 51 of the dart game advancing device 50 receives the converted segment detection signal y transmitted from the dart board device 10 and outputs it to the inverse conversion unit 53 (step S95).

The inverse transform unit 53 substitutes the input transformed segment detection signal y into an inverse transform rule x = y / (a + b + c + d) (substitutes into the inverse transform function f '(y) = y / (a + b + c + d)) to restore the original segment detection signal x before conversion and output it to the game advancement processing unit 55 (step S96). The game advancement processing unit 55 advances the game using the segment detection signal x (step S97). The display unit 56 displays a predetermined screen in accordance with the processing of the game advancement processing unit 55 (step S98), and guides the user to use the dart board device 10 to perform a dart game.

As described above, the conversion rule determination unit 19 of the dart board device 10 determines a conversion rule for changing the section detection signal based on the password specified by the dart game advancing device 50. The dart game advancing device 50 also uses the decided by the password Inverse transformation rules, so there is no such change Even if another device of the change rule determination unit 19 is input with the password designated by the dart game advancing device 50, it cannot determine a conversion rule corresponding to the inverse conversion rule used by the dart game advancing device 50.

As a result, the other devices cannot accurately convert the segment detection signals by the dart game propulsion device 50, so that the dart game propulsion device 50 is prevented from being inactivated by signals from other than the dart board device 10 which is a regular dart board device. Justifiable game advancement. In addition, the password specified by the dart game advancing device 50 is input to the dart board device 10 using a plurality of segment members 1101 to 1182. The dart board device 10 determines a conversion rule based on the password input using the plurality of segment members 1101 to 1182. The device 10 does not need to configure a receiving function for receiving a transmission signal in order to determine a conversion rule.

In addition, as described above, the segment detection signal is the second-order information of the magnification and the fraction, but the magnification and the fraction may be transformed by the transformation rule and the inverse transformation rule, respectively, or only one transformation may be used. For the magnification of the conversion magnification, the magnification can also be represented by "1", "2", and "3".

Next, the timing of determining the conversion rule and the inverse conversion rule will be described. In one embodiment, when the dart board device 10 is first used with a certain dart game advancing device 50 to constitute the dart game system 100, for example, when the dart board device 10 is purchased and first used with the dart game advancing device 50, Or, when a computer program product is downloaded and installed on a smart phone or the like and first used with a certain dart board device 10, a conversion rule and an inverse conversion rule are determined. In addition, in other embodiments, the inverse transformation rule is provided in advance as a given object to a computer program product. Product.

The dart game system 100 according to the present embodiment updates the conversion rule and the inverse conversion rule under predetermined conditions. The conditions (time) for updating the transformation rule and the inverse transformation rule can take various conditions into consideration. The conditions of the following examples can be used individually or in combination.

When a predetermined reset operation is performed on the operation input section 21 of the dart board device 10, the conversion rule and the inverse conversion rule may be updated. When a reset operation is performed on the operation input unit 21 of the dart board device 10, the transmitting unit 22 transmits a reset signal to the dart game advancing device 50, and the conversion rule determining unit 19 cancels the determined conversion rule corresponding to the reset operation.

When the dart game advancing device 50 receives the reset signal through the receiving unit 51, the inverse conversion rule determination unit 52 cancels the determined inverse conversion rule, and the password generation unit 54 generates a new password. When a new password is generated, the inverse transformation rule determining section 52 uses the password generated by the password generating section 54 to generate an inverse transformation rule (step S83 in FIG. 8), and the transformation rule determining section 19 determines a transformation rule based on the new password input by the user. (Step S87 in FIG. 8).

When a predetermined reset operation is performed on the operation input unit 57 of the dart game advancing device 50, the conversion rule and the inverse conversion rule may be updated. When the operation input unit 57 of the dart game advancing device 50 is reset, the inverse conversion rule determination unit 52 cancels the determined inverse conversion rule, and the password generation unit 54 generates a new password. When a new password is generated, the inverse transformation rule determining section 52 uses the password generated by the password generating section 54 to generate an inverse transformation rule (step S83 in FIG. 8), and the transformation rule is determined. The unit 19 determines a conversion rule based on the new password input by the user (step S87 in FIG. 8).

In addition, it is also possible to forcibly (for example, periodically) cancel the conversion rule and the inverse conversion rule. That is, when a predetermined condition is satisfied, the conversion rule determination unit 19 automatically cancels the determined conversion rule, and the inverse conversion rule determination unit 52 may automatically cancel the determined inverse conversion rule. The password generation unit 54 generates a new password based on a user operation or automatically when the inverse conversion rule determination unit 52 cancels the determined inverse conversion rule.

Therefore, since the user needs to forcefully decide the conversion rule again, even if an improper actor is required to grasp the conversion rule of a regular dart board device through any improper method, he can use a machine other than the regular dart board device to forge. Arbitrary (the highest score in the game) segment detection signals. Whenever the transformation rules and inverse transformation rules are canceled, such improper methods have to be used, which can reduce the use of improper machines to forge segment detection signals.

In addition, in the above-mentioned embodiment, when the password designated by the dart game advancing device 50 is input into the dart board device 10, the segment is used, and the conversion rule determination unit 19 recognizes the number input by the user based on the segment detection signal, but it is not limited to this. For example, when the dart board device 10 includes another operation input mechanism such as a digital key, the operation input mechanism may receive a password input from the user.

In addition, in the above embodiment, y = Ax is adopted as the transformation rule, x = y / A is adopted as the inverse transformation rule, that is, a function f is adopted as the transformation rule, and an inverse transformation function f ^{-1 is} adopted as the inverse transformation rule of function f. However, the transformation rule and the inverse transformation rule are not limited to this. The transformation rule may be determined based on a password, and the inverse transformation rule may be a rule that inversely transforms the section detection signal transformed by the transformation rule. For example, transformation and inverse transformation can also be encryption and decryption. In addition, the conversion rule and the inverse conversion rule may not be determined based on all designated passwords, and a part of the password may be a dummy password that is not used in the determination of the conversion rule and the inverse conversion rule.

In the above embodiment, the inverse transformation rule is determined based on the password. However, the inverse transformation rule may be determined on the contrary. For example, as shown in the above embodiment, when the inverse transformation rule is x = y / A and the inverse transformation rule is x = y / 10 (A = 10), the password is determined as a = based on the inverse transformation rule. 1. b = 2, c = 3, and d = 4, and the conversion rule determination unit 19 determines the conversion rule as y = Ax = (a + b + c + d) x = 10x based on the password.

The above describes suitable embodiments of the present invention considered at the current time, but various modifications can be made to this embodiment, and all these modifications within the inventive concept and scope of the present invention are meant to be included in the protection scope of the claims. .

As described above, according to the present invention, there is such an effect that the dart game advancing device can be prevented from performing improper game advancing based on a signal from a device other than a regular dart board device, and it is not necessary to configure a receiving function for a regular dart board. The device determines the transformation rules, and the present invention is useful for, for example, a dart game system.
