  The turntable type input unit provided in the conventional game machine controller described in Patent Document 1 has a structure in which one slide disk is simply fitted to the controller body, and whether or not the turntable has rotated. And it is comprised so that the rotational speed of a turntable may be detected. For this reason, the game machine controller of Patent Document 1 can simulate so-called scratch play in which various scratch sounds are generated by rotating the record board irregularly by hand while contacting the record hands. However, it is not possible to enjoy the pitch bend operation for changing the rotation speed of the turntable that is rotating automatically.

  The input device of Non-Patent Document 1 has a double structure of a top plate that enables a scratch operation and a side rotation detection unit that enables a pitch bend operation in order to enable a pitch bend operation. A touch sensor is used for the top plate. For this reason, there is a problem that the manufacturing cost of the controller increases, and it becomes expensive to use as a controller for a home game.

  An object of the present invention is to provide an inexpensive turntable type input device capable of performing both a scratch operation and a pitch bend operation.

  Another object of the present invention is to provide a turntable type input device, a turntable type input device input operation determination method, and a turntable type input device program capable of determining a player's operation intention with a simple configuration. There is to do.

  Another object of the present invention is to provide a turntable type input device, a method for determining an input operation of the turntable type input device, and a turntable type capable of detecting whether or not the player touches the rotating body with a simple configuration. To provide a program for an input device.

  Another object of the present invention is to provide a turntable type input device and a turntable type capable of detecting whether a player is touching a rotating body using a grip type game controller used in a commercially available home game. An object of the present invention is to provide an input device input operation determination method and a turntable type input device program.

  Another object of the present invention is to provide a turntable type input device capable of detecting whether a player touches the rotating body based on whether the rotating body is tilted, and an input operation determination method for the turntable type input device. And a program for a turntable type input device.

  The present invention aims to improve a turntable type input device including a rotating body, a rotation detection unit, and a pressing operation detection unit. The rotating body has a shape imitating the shape of the turntable of the record, and rotates around the rotation center. The rotation detection unit detects the rotation of the rotating body. The rotation detection unit may be configured to detect the rotation speed and rotation amount of the rotating body. The pressing operation detection unit detects whether or not the player touches the rotating body. When an external force is applied to the plate surface, the rotating body is supported by the support structure so as to be inclined about the rotation center. The turntable type input device includes a multi-axis sensitive acceleration sensor capable of detecting accelerations in a plurality of axial directions, and is configured to output a detection result of the acceleration sensor. In the present invention, when the pressing operation detection unit determines that an external force is applied to the rotating plate from the output of the acceleration sensor and the rotating plate is inclined at a predetermined angle or more, the player touches the rotating plate. judge. According to the present invention, when the pressing operation determination unit determines that an external force is applied to the rotating plate and the rotating plate is inclined by a predetermined angle or more, it is determined that the player touches the rotating plate. The player can naturally play without waiting for the feeling that a predetermined switch is being pressed.

  In particular, in the present invention, an acceleration sensor provided in a grip-type input device used by being gripped by a player can be used as the sensor unit of the pressing operation detection unit and the sensor unit of the rotation detection unit. In this case, the grip-type input device includes at least a multi-axis sensitivity acceleration sensor capable of detecting accelerations in a plurality of axial directions and a communication function, and is configured to output the detection result of the acceleration sensor and rotate. It is operably stored in a storage section provided on the body. Needless to say, the grip-type input device may include an operation switch such as a push switch type. The communication function enables the acceleration sensor to be used as the sensor unit of the rotation detection unit. The acceleration sensor is a multi-axis sensitive acceleration sensor that can detect accelerations in a plurality of axes (usually three axes). In this case, it can be determined from the change in the acceleration signals in the plurality of axial directions of the acceleration sensor of the grip-type input device that an external force is applied to the rotating plate and the rotating plate is inclined. Specifically, when a triaxial acceleration sensor is used as the acceleration sensor, the first axis is arranged in the radial direction of the rotating body, and the second axis is arranged in a tangential direction perpendicular to the radial direction. . And it is preferable to arrange | position the 3rd axis | shaft so that it may become parallel to the direction where a rotation center extends. With this arrangement, the acceleration signal in the direction in which the second axis extends can be used to detect the rotational speed of the rotating body. Further, the inclination of the rotating plate can be determined from the acceleration signal in the direction in which the first axis extends and / or the change direction of the acceleration signal in the direction in which the third axis extends. Therefore, a pressing operation determination unit is provided for determining that the player is touching the rotating plate when it is determined that the rotating plate is inclined by applying an external force to the rotating plate from the detection result output from the acceleration sensor. A pressing operation detection unit is configured. When the external force is applied to the plate surface, the rotating body is supported by a support structure that supports the rotating body so as to be inclined about the rotation center. With this configuration, the rotation of the rotating body is divided into a state where an external force is applied to the rotating body and the rotating plate is inclined, and a state where no external force is applied to the rotating body and the rotating plate is not inclined. It can be distinguished from the operation. For example, the rotation of the rotating body when the rotating plate is tilted can be a scratch operation, and the rotation of the rotating body when the rotating plate is not tilted can be a pitch bend operation. In particular, when the grip type input device has an operation switch such as this operation switch push switch type, the operation switch of the grip type input device is not used as a pressing operation detection unit. Can be used. In addition, since a grip type game controller that already exists in the market, for example, can be used as the grip type input device, the turntable type input device can have a simple configuration.

  Since a commercially available grip type input device has a function of communicating with the game machine body, data can be exchanged using the communication function as it is. However, it goes without saying that the turntable type input device may be provided with a communication function for communicating with the grip type input device. If comprised in this way, the operation result of an operation switch and the detection result of an acceleration sensor can be reliably output via a turntable type input device. In particular, when a communication function is provided in the storage portion, communication between the turntable type input device and the grip type input device can be ensured.

It should be noted that what operation is performed on the combination of the rotation of the rotating body and the presence / absence of the inclination of the rotating plate can be appropriately determined according to the contents of the target for which the turntable type input device is used. Of course.

  The pressing operation determination unit outputs the greatest change when the rotation plate is tilted due to an external force applied to the rotation plate among the accelerations in the biaxial direction or more output from the multi-axis sensitivity acceleration sensor. When the acceleration in one axial direction or the combined acceleration of the acceleration in the one axial direction and the acceleration in the other axial direction exceeds a predetermined threshold, it is determined that the rotating plate is inclined at a predetermined angle or more. Can do. With this configuration, if a detection result exceeding the threshold is not obtained, it is not determined that the pressing operation has been performed. Therefore, the player may erroneously apply the force applied to the rotating body only to rotate the rotating body. It is possible to prevent the pressing operation from being determined.

  When providing a multi-axis sensitive acceleration sensor that can detect acceleration in multiple axes without using a grip-type input device, the key top does not protrude on the surface of the turntable. The appearance and feel of the turntable are not impaired.

  The present invention can also be understood as an input operation determination method for a turntable type input device. A turntable type input device is provided with a multi-axis sensitivity acceleration sensor capable of detecting accelerations in a plurality of axes and a communication function, and is configured to output a detection result of the acceleration sensor and is used by being gripped by a player It has a grip type input device and a function to communicate with the grip type input device, and has a storage portion for storing the grip type input device, and has a shape simulating the shape of a turntable of a record, and a rotation center. When the rotary body is a turntable type input device that is supported by a support structure so as to incline around the rotation center when an external force is applied to the plate surface. Is detected by the rotation detection step for detecting the rotation of the rotating body from the acceleration detected by the multi-axis sensitivity acceleration sensor and the multi-axis sensitivity acceleration sensor. When it is determined from the speed that an external force is applied to the rotating plate and the rotating plate is inclined at a predetermined angle or more, a pressing operation determining step for determining that the player touches the rotating plate and a detection of the rotation detecting step A player operation determination step of determining a player's operation based on the result and the determination result of the pressing operation determination step is executed.

  The turntable type input device is composed of a rotating body having a shape imitating the shape of a turntable of a record and rotated around the center of rotation. When an external force is applied to the plate surface, the rotating body has a center of rotation. A turn that is supported by a support structure so as to incline about the center and that is equipped with a multi-axis sensitive acceleration sensor capable of detecting acceleration in a plurality of axial directions, and configured to output the detection result of the acceleration sensor. In the case of a table type input device, an external force is applied to the rotating plate from the rotation detection step for detecting the rotation of the rotating body from the acceleration detected by the multi-axis sensitivity acceleration sensor and the acceleration detected by the multi-axis sensitivity acceleration sensor. Is added and it is determined that the rotating plate is inclined at a predetermined angle or more, a pressing operation determining step for determining that the player is touching the rotating plate, A detection result of the detecting step, executing a player operation determination whether an operation of the player based on the determination result of the pressing operation determining step.

  The present invention can also be understood as a program that implements a function necessary for determining the operation of the turntable input device using a computer provided in the turntable input device. A turntable type input device is provided with a multi-axis sensitivity acceleration sensor capable of detecting accelerations in a plurality of axes and a communication function, and is configured to output a detection result of the acceleration sensor and is used by being gripped by a player It has a grip type input device and a function to communicate with the grip type input device, and has a storage portion for storing the grip type input device, and has a shape simulating the shape of a turntable of a record, and a rotation center.

A rotation detecting function for detecting the rotation of the rotating body based on the detected result of the acceleration sensor, and an external force is applied to the rotating plate based on the detection result of the acceleration sensor transmitted from the grip type input device to If it is determined that the player is tilted more than an angle, the player is determined based on the pressing operation determination function that determines that the player is touching the rotating plate, the detection result of the rotation detection function, and the determination result of the pressing operation determination function. It can be grasped as a program for a turntable type input device that realizes a player operation determination function for determining the operation.

Since the acceleration sensor and the communication function realizing means are mounted inside the grip-type game controller 363, illustration is omitted. The grip-type game controller 363 is stored in the storage unit 361 only in a posture in which the player can operate the operation switch 315. The multi-axis sensitivity acceleration sensor mounted in the grip-type game controller 363 functions as a sensor unit of the pressing operation detection unit and a sensor unit of the rotation detection unit. The grip-type game controller 363 outputs the detection result of the acceleration sensor via a communication function (not shown). The storage unit 361 of the slide disk 313 is provided with a communication function (not shown) that communicates with the grip-type game controller, and the detection result of the acceleration sensor is input.

In the turntable type input device of the present embodiment, for example, when the output from the acceleration sensor is detected by the rotation operation of the slide disk 313, when the slide disk 313 is inclined at a predetermined angle or more, Based on the output from the acceleration sensor, the pressing operation determination unit determines that the player is touching the slide disk 313 for the scratch operation, and superimposes it on the music for reproducing the sound effect of the scratch play. Further, when the output from the acceleration sensor is detected, if the slide disk 313 is not inclined more than a predetermined angle, the pressing operation determination unit causes the player to perform a scratch operation on the slide disk 313 based on the output from the acceleration sensor. Therefore, the pitch bend play sound effect is superimposed on the music to be played. With this configuration, since the operation switch 315 of the grip-type game controller 363 is not used as the pressing operation detection unit, the operation switch 315 can be used for other functions.
