In the above case, it is determined in the abnormality detection step whether or not the input electric signal is necessary for the game apparatus main body, and if it is not necessary, the electric signal input restriction by the restriction member is performed. Is considered insufficient,
An alarm indicating that the input device is abnormal is issued in the alarm step.

For example, when the game device main body that can be used as a plurality of types of game devices by replacing the stored game program is provided with a button input device, depending on the game program to be stored, the button input provided in advance is provided. The device may not be necessary. In that case, if it is detected by the present invention whether the restriction member is attached to the button input device and the input of the electric signal is correctly restricted, the player of the game device can use the wrong input device to play the game. It is possible to easily prevent the situation.

According to a fifth aspect of the present invention, movements of tilting the lever in a plurality of directions can be inputted to the game apparatus main body as electric signals corresponding to the tilting directions of the lever, and the movement of the lever is regulated to move the lever.

According to the fifth aspect of the present invention, by exchanging the limiting member, the tilting direction of the lever is limited to, for example, two directions, four directions, eight directions, etc., and as a result, the corresponding input is made. In the case where the game device is provided with an input device whose type of electric signal is limited, it is determined in the abnormality detection step whether or not the input electric signal is necessary for the main body of the game device, and it is unnecessary. If it is the case, it is considered that the input restriction of the electric signal by the restriction member is insufficient, and an alarm indicating that the input device is abnormal is issued in the alarm step.

In this way, the situation in which an inappropriate limiting member is erroneously attached to an input device equipped with a lever and an unnecessary electric signal is input is simplified without newly attaching a sensor or the like to the input device. It can be detected, and it is possible to effectively prevent a player of the game device from playing a game using an incorrect input device.

According to a sixth aspect of the present invention, there is provided an abnormality detecting method for an input device, wherein a limiting member capable of limiting the input of an electric signal to the game device body is detachably provided. When the electric signal to be released from the input restriction by the member is not included in the electric signal input by the input device a predetermined number of times in succession, the input restriction of the electric signal by the restriction member is normally performed. If there is an abnormality detection step for determining that the input device is abnormal, and if it is determined by the abnormality detection step that the input of the electric signal by the limiting member is not normally performed, it is determined that the input device has an abnormality. And an alarm step for issuing an alarm.

According to a sixth aspect of the present invention, the input device can be used as an input device of a different type by replacing the limiting member, or the use of the input device can be temporarily stopped.

There is a case where the limiting member is erroneously attached to the device and a necessary electric signal is not input. In that case, according to the present invention, it is possible to easily detect that the restriction member is attached to the button input device and the input of the electric signal is restricted by mistake, and the player of the game device makes an error. It is possible to easily prevent a situation where a game is played using the input device.

According to a seventh aspect of the present invention, movements of tilting the lever in a plurality of directions can be input to the game apparatus main body as electric signals corresponding to the tilting directions of the lever, and the movement of the lever is regulated to move the lever. A method for detecting abnormality of an input device, wherein a restriction member for restricting a tiltable direction is replaceably provided, and an electric signal corresponding to a tilting direction of a lever for which restriction by the restriction member should be released for the game apparatus main body.

BEST MODE FOR CARRYING OUT THE INVENTION The present inventor has recognized the following problems that occur when setting up a game device.

FIG. 1 shows an input device 1 of an arcade game machine.
FIG. 3 is a perspective view showing a lever input device which is one of the two, and FIG. 2 is an exploded perspective view showing the lever input device. The lever input device shown in these drawings includes a lever 10, a supporting member 12, a relay switch 14, a bottom member 16, and a limiting member 18. The lever 10 is formed by attaching a spherical handle member 22 to one end of a shaft member 20, and the shaft member 20 is inserted through the support member 12, the bottom member 16, and the limiting member 18. The support member 12 is attached to the main body of the game device (not shown), and the lever input device is fixed to the game device. Further, the support member 12 supports a fulcrum 24 of the lever 10, and the lever 10 can be tilted in all directions around the fulcrum 24. Further, four relay switches 14 are provided on the back surface side of the support member 12, and are attached by being pressed into contact with each other by a bottom member 16. Also, the bottom member 1
A restricting member 18 that restricts the tilting movement of the lever 10 by being in contact with the side surface on the other end side of the shaft member 20 is attached to the shaft 6.

FIG. 3 is a view showing the arrangement of the relay switch 14 of the lever input device. As shown in the figure,
Four relay switches 14 are provided on the back side of the support member 12.
However, the respective switch pieces 26 are provided so as to surround four sides of the shaft member 20 of the lever 10.

In the lever input device having the above construction, when the player tilts the lever 10, a part of the side surface of the shaft member 20 comes into contact with the switch piece 26 of the relay switch 14, so that any one of the relay switches 14 is turned on. It becomes conductive. Here, the above-mentioned restriction member 18 is attached to the present lever input device, and the direction in which the lever 10 can be tilted is restricted. Therefore, the direction in which the lever 10 can be tilted can be changed by changing the shape of the limiting member 18. FIG. 4A is a plan view showing the limiting member 18, and FIGS. 4B and 4C are plan views showing a modification thereof. According to the limiting member 18 shown in FIG. 4A, the lever 10 is tilted in all directions, and as a result,
By the signal state of the relay switch 14, all eight directions can be identified and input. That is, when the shaft member 20 tilts toward one side of the support member 12,
Each relay switch 14 becomes conductive independently,
When the shaft member 20 is tilted in an oblique direction, two adjacent relay switches 14 are both brought into conduction. Therefore, the inclinations of the lever 10 in eight directions are identified and input as eight types of electrical signals.

If the limiting member 28 shown in FIG. 4B is attached instead of the limiting member 18 of the lever input device, the lever 10 is limited in the tilting direction to only four directions.
That is, the restricting member 28 has a portion 32 that protrudes to a position corresponding to the oblique inclination of the lever 10 as compared with the restricting member 18 shown in FIG. 4A. Is unable to lean effectively.

If the limiting member 30 shown in FIG. 4C is attached instead of the limiting member 18 of the lever input device, the tilt direction of the lever 10 is limited to only two directions.
That is, the limiting member 30 is the shaft member 2 of the lever 10.
It is formed so as to allow movement of only one direction of 0, and only two of the four relay switches 14 facing each other are in a conductive state.

According to the lever input device described above, when the game program is replaced and the game device is used for a different game, the restricting member is replaced so that the direction in which the lever 10 can be tilted corresponds to the game program. Can be changed. For example, when the game device is used as a puzzle game, the limiting member 28 may be attached to the lever input device and used as a four-direction type lever input device. If necessary, the limiting member 18 may be attached to the lever input device to be used as an eight-direction type lever input device. Thus, one lever input device can be used as a plurality of types of lever input device.

However, in the past, when replacing the game program, it was not uncommon for the player to forget to replace the limiting member, and there were cases where the player did not use the game device using a lever input device of an appropriate type. . As a result, the player may not be able to fully enjoy the original entertainment property of the game program. Moreover,
It is difficult to distinguish the replacement error of the restriction members 18, 28, 30 from the appearance of the game device.
In many cases it was left alone.

In view of the above problems, the inventor of the present invention succeeds in solving this problem by providing an abnormality detection program in the game program for detecting that the lever input device is installed in a different type. It was

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 5 is a diagram showing an example of the configuration of a game device using the abnormality detecting method for an input device according to the present invention.
The game device shown in the figure has a predetermined time (for example, 1/6).
A game device by so-called real-time image processing that updates a display image every 0 seconds) to form a moving image, and includes an input device 32, a central processing unit 34, an output device 36,
A storage device 38 is provided. The input device 32 is a device for a player to input an electric signal corresponding to operation information of a game character to the central processing unit 34,
Here, in particular, the lever input device already shown in FIG. 1 is used. The output device 36 is a speaker for outputting audio, a display for outputting images, etc., and is a device for outputting various game information according to a game program. Further, the storage device 38 includes a memory for storing a game program, a control program, etc., and a backup memory for storing high score information and the like. The central processing unit 34 carries out various arithmetic processes according to input / output control of these devices and a game program stored in the storage unit 38.

FIG. 6 is a flow chart showing the abnormality detection processing of the input device according to this embodiment. The flow chart shown in the figure is
The abnormality detection process of the input device when the limiting member 18 is accidentally attached to the lever input device instead of the limiting member 28 is shown. That is, when the input means required for the game program is a four-direction type lever input device, the abnormality detection process is performed when the lever input device is accidentally attached as an eight-direction type. Incidentally, in the flow chart shown in the figure and the flow chart shown in order below, corresponding software programs are stored in the storage device 38 and executed by the central processing unit 34.

The processing according to the flow chart shown in the figure is performed at predetermined time intervals. First, the central processing unit 3 is used.
4 reads the signal state of the relay switch 14 (S
1). And when entering in the diagonal direction, that is,
When it is determined that the two adjacent relay switches 14 are simultaneously in the conductive state (S2), the alarm flag is stored as 1 in the backup memory of the storage device 38 (S3), and the process is ended. If the lever 10 is not tilted in the oblique direction (S2), the process is ended as it is.

Generally, in the real-time image display processing, the input electric signal is read by the central processing unit 34 every predetermined time and used as game operation information or the like.
The abnormality detecting method of the input device according to the present invention succeeds in detecting the installation abnormality of the lever input device by effectively utilizing this electric signal.

FIG. 7 is a flow chart showing a processing procedure for displaying a warning according to the warning flag stored as described above, which is executed when the power source of the present game device is turned on.

According to the flow chart shown in the figure, first, the central processing unit 34 reads the alarm flag stored in the backup memory of the storage unit 38, and when the alarm flag is 1 (S11). Erroneously determines that the lever input device is installed in the 8-direction type, and displays a warning message such as "Please change to the 4-direction type" by the output device 36 (S12). After that, if any input is made by the input device (S1
3) Then, the alarm flag is changed to 0 (S14), and the process ends. When the warning flag is not 1 (S11)
It is determined that the lever input device is properly installed, and the processing ends.

As described above, when an abnormal input of an electric signal is made due to a mistake in setting up the input device or a failure, the alarm flag is not immediately issued but the fact that an error has occurred is stored in the alarm flag. In addition, if a warning is given when the game device is started up, it is possible to avoid the problem that a warning is displayed while the player is playing the game. In particular, in the arcade game machine, it is customary for the sales person to turn on the power supply before business, and it is preferable to display a warning at this time. The abnormal alarm of the input device is not limited to the display of the warning message, and an alarm by sound or lamp can be issued.

Next, when the limiting member 28 is mistakenly attached to the lever input device instead of the limiting member 18, that is, the input means necessary for the game program is 8
In case of directional type lever input device,
An abnormality detection process when the lever input device is attached as the direction type will be described. FIG. 8 is a flowchart showing the abnormality detection processing of this input device.

In the process shown in the figure, first, the central processing unit 34 reads the electric signal state of the lever input device (S21) and determines the tilt direction of the lever 10 (S22). If the lever 10 is inserted in the diagonal direction, it is determined that the lever input device is installed as an 8-direction type, the number of samples is initialized to 0 (S27), and the process is ended. Here, the number of samples refers to the lever 10 when reading an input signal at a predetermined time interval.
For counting the number of consecutive inputs in the direction other than the diagonal direction are stored in the storage device 38.

Next, when it is determined that the lever 10 is not inserted in the oblique direction (S22), the number of samples is incremented by 1 (S23), and it is determined whether or not the number of samples has reached a predetermined standard. It is determined (S24). Then, if the number of samples does not reach the standard, the processing ends. On the other hand, when the number of samples has reached the reference, it is determined that the lever input device is erroneously installed in the four-direction type, and the alarm flag is stored as 1 in the backup memory of the storage unit (S25). After that, the number of samples is initialized to 0 again (S26), and the process ends.

In short, the processing shown in the figure is processing in which the case where the lever 10 does not enter the diagonal direction for the reference number of times consecutively is regarded as the installation abnormality of the lever input device. When an abnormality is detected, a warning is displayed, for example, when the power of the game device is turned on by the same process as the above-described flow chart of FIG. 7.

According to the abnormality detecting method of the input device described above, it is possible to easily detect the abnormality of the existing input device without providing a sensor for detecting the abnormality.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the present invention can be applied to general input devices for inputting operation information and the like to a game device main body by an electric signal, and also performs abnormality detection of input devices such as buttons and guns in gun shooting games in addition to the lever input device. be able to.

Further, the present invention can also detect an abnormality in an analog input device such as a steering wheel or an accelerator in a drive game. The analog input device is capable of converting an analog amount such as a change in voltage into a numerical value and inputting the numerical value into the game device as an electric signal. 9 and 10 are flowcharts showing the abnormality detection processing of the analog input device using the present invention.

According to the flow charts shown in these figures, first, the input value is read based on the input signal from the analog input device (S31), and the value obtained by subtracting the previous input value from the current input value is moved. Detected as a quantity (S3
2). If the amount of movement is 0 (S33), the current input value is stored in the storage device 38 as the previous input value (S34), and the process is terminated.

When the movement amount is not 0 (S33), it is determined whether or not the input value is updating the maximum value and the minimum value (S35). If the input value is updated, the current input value is updated. The maximum value or the minimum value is stored in the storage device 38 (S36).

Next, it is judged whether or not the value obtained by subtracting the minimum value from the maximum value is within the range required for the game program (S37), and if it is not within the required range, the sample number is incremented by 1 ( S38). When the number of samples reaches the reference value (S39), the alarm flag is stored as 1 (S40), and the number of samples is initialized to 0 again (S41). Thereafter, the input value of this time is stored in the storage device 38 as the input value of the previous time (S34), and the process is ended.

If the value obtained by subtracting the minimum value from the maximum value is not within the range required for the game program (S37), the number of samples is initialized to 0 (S42), and the current input value is set as the previous input value. The data is stored in the storage device 38 (S34), and the process ends.

In the abnormality detecting process of the analog input device described above, in short, it is judged that the analog input device is abnormal when a value exceeding the input value range required for the game program is not continuously input for the reference number of times. ing.
Then, according to the above processing, it is possible to easily detect the abnormality of the existing analog input device without providing a sensor for detecting the abnormality.

In the home game machine, it may be necessary to connect a different input device to the main body of the home game machine depending on the game program. In this case,
An electric signal input from the input device is used to determine whether or not an appropriate input device is connected. If it is determined that the appropriate input device is not connected, a warning display may be given before the game starts.

Further, the processing relating to the abnormality detecting method of the input device of the present invention is not limited to the processing of software, but may be processing by hardware logic or processing by a combination thereof.
