- the plurality of magnets 20 of this example are provided at positions separated from each other in the top view. Therefore, the input device 100 of this example can reduce the influence of the attractive force and the repulsive force between the magnets 20 and suppress the influence of the operation unit 15 on the operation feeling.

- the sensor 40b is provided on the negative side of the circle C2 in which the magnet 20 moves in the Y-axis direction.
- the positions of the sensor 40a and the sensor 40b are not limited to this example as long as the magnetic field of the magnet 20 can be detected.
- the input device 100 can arbitrarily determine the number and position of the magnet 20 and the sensor 40, the degree of freedom in layout is high and it is easy to realize miniaturization.
- the degree of freedom in layout is high and it is easy to realize miniaturization.
- simple wiring can be realized and workability at the time of mounting can be improved.
- the mounting error can be reduced.
- FIG. 6A is a cross-sectional view showing a modified example of the input device 100.
- the heights of the magnet 20 and the sensor 40 are adjusted so as to overlap each other.
- the sensor 40 is arranged at the same height as the magnet 20 in the Z-axis direction.
- the same height may mean that at least one part of the magnet 20 and the sensor 40 overlap in the Z-axis direction.
- the heights of the magnet 20 and the sensor 40 of this example are adjusted so that the centers in the Z-axis direction coincide with each other. By aligning the heights of the magnet 20 and the sensor 40 in the Z-axis direction, the magnetic field input in the Z-axis direction of the sensor 40 is less likely to change even if the magnet 20 moves. As a result, the input device 100 can improve the accuracy of disturbance detection by detecting the magnetic field in the Z-axis direction.
- FIG. 6B is a cross-sectional view showing a modified example of the input device 100.
- the magnetic field generation unit 60 is arranged above the sensor 40.
- the magnetic field generating unit 60 has a first pole 61 and a second pole 62, and generates a magnetic field having a predetermined size.
- the first pole 61 is the S pole and the second pole 62 is the N pole.
- the magnetic field generating unit 60 of this example is fixed above the housing 10, and applies a magnetic field of a predetermined strength to the sensor 40.
- the shape of the magnetic field generating portion 60 of this example is a rectangular parallelepiped, but the shape is not limited to this.
- the first pole 61 is arranged at a position close to the sensor 40, and the second pole 62 is arranged at a position away from the sensor 40, but the first pole 61 and the second pole 62 are conversely the same. It may be arranged. That is, the magnetic field generating unit 60 only needs to be able to apply a magnetic field to the sensor 40 in the Z-axis direction, and its magnetizing direction is not limited.
- FIG. 6C is a top view showing a modified example of the input device 100.
- the magnetic field generating unit 60 is arranged directly above the sensor 40, but it does not necessarily have to be arranged directly above the sensor 40.
- the position of the magnetic field generating unit 60 may be above the sensor 40 and may be a position partially overlapping the sensor 40 in the top view.
- the position of the magnetic field generator 60 depends, for example, on the placement position of other components of the input device 100, or on the strength of the magnetic field desired to be applied in the X and Y axis directions of the sensor 40, or the measurement range of the sensor 40. Depending on the situation, they may be arranged so as to be offset in the X, Y and Z axis directions. Since the magnetic field generating portion 60 is a fixed magnet, a magnet moving portion is unnecessary and there is no limitation on the thinness. Therefore, it can be added within a range that does not affect the thinning of the housing 10.
- the input device 100 of this example can correct the magnetic field data when the temperature changes by applying a magnetic field to the sensor 40 in the Z-axis direction using the magnetic field generating unit 60.
- B x and B z can be expressed by the following equation 1. ..
- B x (20) and B x (60) are the magnitudes of the magnetic fields in the X-axis direction given to the sensor 40 by the magnet 20 and the magnetic field generating unit 60, respectively
- B z (60) is the magnitude of the magnetic field in the X-axis direction. It is the magnitude of the magnetic field in the Z-axis direction applied to the sensor 40.
- the magnet 20 and the sensor 40 are at the same height in the Z-axis direction, the magnet 20 does not apply a magnetic field in the Z-axis direction to the sensor 40.
- the following equation 2 is obtained.
- Equation 2 When the temperature changes by ⁇ T, the magnitude of the magnetic field changes linearly with the temperature, so that Equation 2 is transformed as in Equation 3 below.
- ⁇ 20 and ⁇ 20 are coefficients determined by the magnet material of the magnet 20
- ⁇ 60 and ⁇ 60 coefficients determined by the magnet material of the magnetic field generating unit 60.
- Equation 4 does not include ⁇ T, it can be seen that the displacement of the position coordinates due to the temperature characteristics of the magnet 20 can be prevented by applying the magnetic field in the Z-axis direction using the magnetic field generating unit 60.
- the magnetic field data output by the sensor 40 can be corrected by the above calculation with reference to the magnetic field applied to the sensor 40 by the magnetic field generating unit 60 having the same temperature characteristics. As a result, it is possible to prevent the position coordinates of the detected operation unit 15 from being displaced due to the temperature characteristics of the magnet 20.
- the magnet 20 and the sensor 40 in the Z-axis direction are the same has been described, but the magnet 20 may have a height different from that of the sensor 40 in the Z-axis direction.
- the magnitude of the magnetic field applied to the sensor 40 by the magnetic field generating unit 60 may be larger than the magnitude of the magnetic field applied to the sensor 40 by the magnet 20. That is, when the magnitude of the magnetic field applied to the sensor 40 by the magnet 20 in the Z-axis direction is B z (20), B z (60) may be larger than B z (20).
- the distance between the magnetic field generating unit 60 and the sensor 40 may be smaller than the distance when the magnet 20 and the sensor 40 are in close contact with each other.
- the magnitude of the magnetic field applied to the sensor 40 by the magnetic field generating unit 60 can be made larger than the magnitude of the magnetic field applied to the sensor 40 by the magnet 20. More specifically, as will be described later, in one example, the minimum distance from the intersection P1 to the magnet 20 is 2.5 mm, so that the distance from the upper surface of the sensor 40 to the bottom surface of the magnetic field generating portion 60 is less than 2.5 mm. Therefore, B z (60) can be made larger than B z (20).
- Equation 2 the variable on the right side is only B x (20), whereas in Equation 5, a variable called B z (20) is added, which complicates the calculation. Therefore, for example, by adjusting the arrangement of the magnetic field generating unit 60 and the magnet 20 to make B z (60) larger than B z (20), the above equation 5 is approximated as the following equation 6. As a result, it becomes possible to handle as in the above equation 4.
- FIG. 6D shows an example of a disturbance detection method by the input device 100.
- the input device 100 of this example sets a predetermined threshold value B1 and a threshold value B2 of the magnetic flux density (mT), and when the detected magnetic field in the Z-axis direction exceeds the range from the threshold value B1 to the threshold value B2. Judge that a disturbance has been detected.
- the input device 100 can easily suppress the influence of the movement of the magnet 20 on the magnetic flux density in the Z-axis direction. This makes it possible to improve the accuracy of disturbance detection.
- the threshold value B1 may be a value obtained by subtracting a magnetic field equivalent to the geomagnetism from the minimum value of the magnetic field applied to the sensor 40 when the operation unit 15 is operated in a predetermined pattern.
- the threshold value B2 may be a value obtained by adding a magnetic field equivalent to the geomagnetism to the maximum value of the magnetic field applied to the sensor 40 when the operation unit 15 is operated in a predetermined pattern.
- the value subtracted from the maximum value and the minimum value may be a value having a margin larger than the magnetic flux density due to the geomagnetism. This makes it possible to suppress the influence of the magnetic field generated by the metal component (for example, a spring) magnetized by the magnet 20. In addition, the influence of the magnetic field generated by the movement of the magnet 20 due to the mounting error can be suppressed.
- the threshold B1 and the threshold B2 are ⁇ 500 ⁇ T and +500 ⁇ T, respectively.
- FIG. 6E shows an example of a flowchart of the threshold setting method.
- the flowchart of this example is an example of the process for setting the threshold value for detecting the disturbance in the normal process state.
- step S100 acquisition of magnetic field data is started.
- the acquisition of the magnetic field data may be executed by a processing unit provided inside the input device 100, or may be executed by a processing unit provided outside the input device 100.

- the threshold value is set based on the magnetic field data acquired in step S102.
- the maximum value and the minimum value may be extracted from the magnetic field data acquired in step S102.
- the threshold is set based on the maximum and minimum values of the magnetic field data acquired in step S102 and the geomagnetism. For example, the value obtained by subtracting the magnetic field corresponding to the geomagnetism from the minimum value of the magnetic field data acquired in step S102 is set to the threshold value B1, and the value obtained by adding the magnetic field equivalent to the geomagnetism to the maximum value is set to the threshold value B2. This makes it possible to avoid erroneous detection of disturbance due to the movement of the magnet 20 during normal operation.
- the threshold setting method of this example may be executed at the time of manufacturing the input device 100, may be executed after the input device 100 is mounted on the controller, or may be executed by a user who uses the input device 100. You may. For example, the user may reset the threshold value after setting the threshold value at the time of factory shipment of the input device 100.
- FIG. 6F shows an example of an operation flowchart for processing magnetic field data.
- the processing unit acquires the magnetic field data.
- the magnetic field data in the normal processing state may be acquired.
- the normal processing state refers to a state in which a game is being played using the input device 100, for example, when the input device 100 is a controller for a game.
- the threshold value set in step S104 may be used. If the magnetic field exceeds the threshold value, error processing is executed in step S204, and if the magnetic field does not exceed the threshold value, normal processing is continued in step S206.
- the error processing may be a processing that does not adopt the magnetic field data that exceeds the threshold value, or may be a processing that notifies the user that a disturbance has been detected. In this way, by detecting the disturbance using the 3-axis magnetic sensor for the sensor 40, it is possible to realize the error processing of the disturbance.
- FIG. 7A is an operation flowchart of the system for confirming the normal operation of the sensor 40.
- the processing unit starts communication with the sensor 40.

- the input device 100 can confirm that the magnet 20 and the sensor 40 are correctly arranged and that the sensor 40 is operating normally.
- the determination of whether or not the communication in step S310 is normal may be executed by an authentication operation between the processing unit and the input device 100.
- the processing unit designates the sensor 40 by the slave address and determines the read value of a specific register (device ID). After determining the read value of the device ID, the processing unit may execute a self-diagnosis function (that is, a self-test) and determine whether or not communication is normal based on the result.
- a self-diagnosis function that is, a self-test
- FIG. 7B shows an example of an operation flowchart for acquiring magnetic field data.
- the operation flowchart of this example shows a specific method for determining whether or not the magnetic field data is normal in step S320.
- step S322 the operation unit 15 is operated in a predetermined pattern.
- the processing unit may instruct the user to operate in a predetermined pattern.
- step S324 it is determined whether or not there is an abnormality in the direction of the magnet 20. If there is an abnormality in the orientation of the magnet 20, it is determined that there is an abnormality in the magnetic field data, and if there is no abnormality in the orientation of the magnet 20, it is determined in step S326 whether there is an abnormality in the strength of the magnet 20. If there is an abnormality in the strength of the magnet 20, it is determined that there is an abnormality in the magnetic field data, and if there is no abnormality in the strength of the magnet 20, it is determined in step S328 whether or not the mounting error of the input device 100 is within the allowable range.
- each step is determined using at least one of the magnitude of the magnetic field output, the polarity of the magnetic field output, or the distortion of the magnetic field output obtained by the operation of step S322.
- the order in which steps S324 to S328 are executed may be changed as appropriate. After step S322, at least one of steps S324 to S328 may be executed.
- FIG. 8 is an example of the input device 100 when the magnet 20 is arranged in a repulsive force.
- the input device 100 of this example has the same basic configuration as the embodiment of FIG. 3A.
- the polarities of the input device 100 are arranged so that when the magnet 20a and the magnet 20b approach the sensor 40, they repel each other. In this way, in the case of the repulsive force arrangement in which the magnets 20a and the magnets 20b repel each other, the repulsive force between the two magnets acts in the direction of returning the operating portion 15 to the reference position. Since the return force to the reference position by the spring is applied in the direction of returning the operation unit 15 to the reference position, it is difficult for the user to feel the repulsive force between the magnets 20.
- the attractive force arrangement in which the magnets 20 attract each other, the attractive force acts in the direction of canceling the return force to the reference position by the spring, so that the user can return the operation unit 15 only when the operation unit 15 is tilted in a specific direction. You may get the impression that it is bad. Therefore, by arranging the magnets 20 to repel each other, the operability of the input device 100 can be easily improved.
- the magnet 20 in the case of the attractive force arrangement, it is necessary to attach the magnet 20 to the magnet moving portion 30 in the opposite directions, whereas in the case of the repulsive force arrangement, the magnet 20 may be attached to the magnet moving portion 30 in the same direction. .. Therefore, in the repulsive force arrangement, the same member can be reused for the magnet moving portion 30a and the magnet moving portion 30b, so that mass productivity can be improved.

- the minimum length that can be perceived as a human moving a finger is about 0.1 mm.
- the input device 100 tries to detect 0.1 mm, it is necessary to divide the stroke S1 of about 6 mm of the operation unit 15 into about 60. That is, it is necessary to divide the stroke S1 of the magnet 20 interlocking with the operation unit 15 into about 60.
- the stroke S1 will be described later.
- the magnitude of the geomagnetism is 30 ⁇ T to 60 ⁇ T, and it is necessary to prevent this from affecting the normal operation as much as possible.
- the distance D satisfying such a condition is set to 2.5 mm or more and 4.5 mm or less. This makes it possible to suppress the influence of the geomagnetism during use.
