  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. An operation input device according to an embodiment of the present invention is an operation interface that receives a force from an operator's finger or the like and outputs an output signal that changes in accordance with the received force. An operation input by the operator is detected based on the output signal. By detecting the operation input, it is possible to make the computer grasp the operation content corresponding to the detected operation input.

  For example, in an electronic device such as a home or portable game machine, a portable terminal such as a mobile phone or a music player, a personal computer, or an electric appliance, a display object (for example, a display provided on such an electronic device (for example, An instruction display such as a cursor or pointer, a character, or the like) can be moved according to the operation content intended by the operator. In addition, when an operator gives a predetermined operation input, a desired function of the electronic device corresponding to the operation input can be exhibited.

  FIG. 1 is an exploded perspective view of an operation input device 1 according to the first embodiment of the present invention. FIG. 2 is a cross-sectional view of the operation input device 1 in an initial position state where no operation input is applied. FIG. 3 is an external perspective view of the operation input device 1. The operation input device 1 receives an operator's force input from the Z-axis direction side (upward in the figure) of an orthogonal coordinate system determined by the X, Y, and Z axes. Note that the Z-axis direction is a direction parallel to the Z-axis. Further, “upper” includes diagonally upward, and “lower” includes diagonally downward.

  The operation input device 1 detects contact between the conductive pads 51 to 54 provided in each direction on the lower surface 43 of the direction key 40 and the conductive patterns 61 to 64 provided in each direction on the upper surface 31 of the substrate 30. It is possible to detect that the direction key 40 is pressed in any direction by an operation input.

  The operation input device 1 includes a substrate 30, conductive patterns 61 to 64, a permanent magnet 10, a core 20, a coil 70, a direction key 40, and conductive pads 51 to 54 as main components.

  The substrate 30 is a base portion having an upper surface 31 on which a plurality of conductive patterns (four conductive patterns 61 to 64 in the case of FIG. 1) are arranged. The upper surface 31 is preferably a plane parallel to the XY plane in terms of reducing the height of the operation input device 1. The substrate 30 may be a non-magnetic material, and a specific example thereof is a printed board made of glass epoxy resin. The substrate 30 is fixed inside the case 80.

  The conductive patterns 61 to 64 are fixed electrodes arranged side by side in a circumferential direction of a virtual circle formed by connecting points having the same distance from the origin O. The origin O is a reference point of a three-dimensional orthogonal coordinate system. The conductive patterns 61 to 64 are preferably arranged at equal intervals in the circumferential direction in terms of facilitating calculation of the operator's force vector. The conductive patterns 61 to 64 are arranged every 90 ° in the circumferential direction in four directions of X (+), X (−), Y (+), and Y (−). The X (−) direction is a direction opposite to the X (+) direction by 180 ° on the XY plane, and the Y (−) direction is 180 ° opposite to the Y (+) direction on the XY plane. The direction of the direction. The conductive pattern 61 is disposed on the X axis on the positive side with respect to the origin O, the conductive pattern 62 is disposed on the Y axis on the positive side with respect to the origin O, and the conductive pattern 63 is disposed with respect to the origin O. The conductive pattern 64 is disposed on the negative Y axis with respect to the origin O. The conductive pattern 64 is disposed on the negative X axis.

  The conductive patterns 61 to 64 may be arranged every 90 ° in the circumferential direction in four directions of 45 ° obliquely in the XY plane sandwiched between the X axis and the Y axis. For example, the conductive pattern 61 is arranged in the first quadrant, the conductive pattern 62 is arranged in the second quadrant, the conductive pattern 63 is arranged in the third quadrant, and the conductive pattern 64 is arranged in the fourth quadrant.

  The permanent magnet 10 is a magnet formed in a cylindrical shape by magnetizing a magnetic material such as iron, and is disposed on the upper surface 31 of the substrate 30. The permanent magnet 10 is fixed to the central portion of the lower surface 43 of the direction key 40 so that the axis S in the Z-axis direction passing through the center of gravity of the permanent magnet 10 passes through the origin O. The upper surface 11 and the lower surface 12 of the permanent magnet 10 are magnetized surfaces. The lower surface 12 is a portion facing the upper surface 31 of the substrate 30. By making the lower surface 12 on which the permanent magnet 10 contacts the substrate 30 flat, the operation input device 1 can be reduced in height, and the position of the direction key 40 in the initial position can be stabilized.

  The core 20 and the coil 70 disposed around the core 20 are disposed on the opposite side of the permanent magnet 10 with the substrate 30 interposed therebetween. The core 20 forms an electromagnet as a whole by combining with the coil 70. The core 20 is a columnar magnetic body (for example, iron). The core 20 is fixed to the lower surface 32 of the substrate 30 so that the upper surface 21 of the core 20 faces the lower surface 12 of the permanent magnet 10 across the substrate 30. The core 20 is a magnetic body for generating a magnetic field H exerting a magnetic force F that brings the permanent magnet 10 into contact with the upper surface 31 of the substrate 30 between the lower surface 12 of the permanent magnet 10. That is, the direction of the magnetic force F (the direction of the magnetic field H) is downward in the figure.

  The direction key 40 receives an operation input in the same direction as the magnetic force F (magnetic field H) (that is, an operation input from the upper side to the lower side in the drawing), whereby the upper surface 31 of the substrate 30 and the permanent magnet 10 are operated. This is an operation unit that tilts together with the permanent magnet 10 located on the Z-axis with the contact part as a fulcrum. The direction key 40 tilts together with the permanent magnet 10 in the X (+/−) and Y (+/−) directions according to the position where the operation is input.

  The direction key 40 is an operation member provided on the side where the operator's force is input to the substrate 30. The direction key 40 is a plate-shaped disk key, and is disposed above the conductive patterns 61 to 64 provided on the substrate 30. The direction key 40 includes a lower surface 43 facing the upper surface 31 of the substrate 30 on which the conductive patterns 61 to 64 are disposed, and an operation surface 41 on which an operator's force can act (the upper surface of the direction key 40 in the drawing). ).

  The direction key 40 is provided with a flange 42. On the lower surface 43 (in particular, the lower surface of the flange 42) where the direction key 40 faces the substrate 30, the same number of conductive pads 51 to 54 as the plurality of conductive patterns 61 to 64 disposed on the upper surface 31 of the substrate 30 are provided. Is provided. The conductive pads and the conductive patterns are one-on-one, and are a pair of detection units arranged at positions facing each other. The conductive pad is an elastic body having conductivity. The direction key 40 brings the conductive pad into contact with the conductive pattern when the operator's force acts on the operation surface 41 and the lower surface 43 of the direction key 40 approaches the upper surface 31 of the substrate 30. The input direction of the operation input with respect to the origin O can be detected by detecting the contact between the conductive pad and the conductive pattern by any of the four pairs of detection units.

  The operation input device 1 is attached and supported inside the case 80 so that the direction key 40 is fitted into a circular opening 81 formed in the upper part of the case 80. The case 80 is a housing of an electronic device such as a mobile phone or a game machine to which the operation input device 1 is attached. The operation input device 1 itself may include a case 80. The case 80 is guided by the opening 81 so that the direction key 40 can tilt downward.

  Next, the movement of the operation input device 1 will be described.

  FIG. 4 is a cross-sectional view of the operation input device 1 in a state where the X (+) side of the direction key 40 is pushed in the Z (−) direction and stroked until the conductive pad 51 contacts the conductive pattern 61. FIG. 5 is a view of the conductive pattern 61 as viewed from above. The conductive pattern 61 is a conductor such as a copper foil and is divided into at least two or more surfaces (the same applies to the other conductive patterns 62 to 64). FIG. 5 shows two divided surfaces 61 a and 61 b of the conductive pattern 61 formed on the upper surface 31 of the substrate 30.

  When the directional key 40 is tilted by the operation input with the edge B on the X axis positive side of the permanent magnet 10 as a fulcrum, when the conductive pad 51 contacts the conductive pattern 61, the split surfaces 61 a and 61 b are short-circuited via the conductive pad 51. To do. Each of the dividing surfaces 61a and 61b is connected to a detection circuit (not shown). When the short circuit is detected by the detection circuit, the direction key 40 is pressed at the point of action A on the side where the pair of detection parts composed of the conductive pad 51 and the conductive pattern 61 are arranged with respect to the origin O. Can be detected. The direction key 40 tilts until the flange 42 contacts the inner upper surface 82 of the case 80 on the side opposite to the operation input point A. Alternatively, on the opposite side of the operation point A of the operation input and before the flange 42 contacts the inner upper surface 82 of the case 80, the conductive pads of the pair of detection units on the side of the operation point A and the conductive pattern come into contact with each other. The tilt angle of the key 40 may be limited.

  Next, the automatic return function of the direction key 40 to the initial position state will be described with reference to FIGS.

  FIG. 6 is a cross-sectional view of the automatic return mechanism in the initial position state where no operation input is given. In the initial position state, the direction key 40 has the lower surface 12 of the permanent magnet 10 on the upper surface 31 of the substrate 30 by the attractive force F generated by the magnetic force (magnetic field) generated between the permanent magnet 10 fixed to the lower surface 43 and the core 20. Because of the close contact, it is always kept parallel to the substrate 30.

  FIG. 7 is a cross-sectional view of the automatic return mechanism in an operation state in which the direction key 40 is pressed in the X (+) direction side. The directional key 40 and the permanent magnet 10 are used together with the edge B on the X axis positive side of the lower surface 12 of the permanent magnet 10 (that is, the portion where the lower surface 12 contacts the upper surface 31 on the X (+) direction side with respect to the axis S). Tilt. As shown in the drawing, the direction key 40 is tilted with the edge B on the X axis positive side of the lower surface 12 as a fulcrum, so that the lower surface 12 can be opposed to the upper surface 21 of the core 20 even when the direction key 40 is tilted. it can. Therefore, the attractive force F between the lower surface 12 and the upper surface 21 is used not only as a force for bringing the permanent magnet 10 into contact with the substrate 30 but also as a force that resists the tilting of the direction key 40 in the direction away from the core 20. Can also be used. That is, the automatic origin return mechanism that returns the direction key 40 tilted by the operation input on the X (+) direction side to the initial position state of FIG. 6 is realized with a simple configuration.

  Since the contour of the bottom surface (that is, the lower surface 12) of the cylindrical permanent magnet 10 is a circle, the edge B corresponds to one point on the circumference. Even if the permanent magnet 10 and the substrate 30 are in point contact at the edge B with the direction key 40 tilted, the tilting force of the direction key 40 can be stabilized because the attractive force F also acts on the edge B. Can do. Further, since the contour of the lower surface 12 is a circle, any point on the contour can be used as a fulcrum for tilting the direction key 40. Therefore, since the direction key 40 can be tilted in an arbitrary direction of 360 ° with respect to the origin O, an operation input in an arbitrary direction can be detected.

  FIG. 8 is a cross-sectional view of the automatic return mechanism in an operation state in which the direction key 40 is pressed in the X (−) direction side. The fulcrum in this case is the edge C on the X-axis negative side of the lower surface 12 of the permanent magnet 10. In this case as well, there is an effect that the direction key 40 tilted by the operation input on the X (−) direction side is returned to the initial position state of FIG.

  FIG. 9 is a cross-sectional view of the automatic return mechanism when the direction key 40 is displaced. By making the diameter of the lower surface 12 of the permanent magnet 10 and the diameter of the upper surface 21 of the core 20 substantially the same, even if the direction key 40 is displaced relative to the substrate 30 on the XY plane, the permanent magnet 10 Since the suction force F is generated so that the axial centers of the core 20 and the core 20 overlap with each other, there is an effect of returning to the initial position state of FIG.

  Next, the principle that the operation input device 1 applies a forced load (feedback force) to the fingertip of the operator via the direction key 40 will be described with reference to FIGS. In order to generate a feedback force, the permanent magnet 10 is end-face magnetized in a direction perpendicular to the axis of the coil 70. For example, the upper surface 11 of the permanent magnet 10 is magnetized to the S pole, and the lower surface 12 is magnetized to the N pole. The opposite polarity (the lower surface 12 is the S pole) may be used for the magnetic pole property.

  FIG. 10 is a diagram for explaining the generation principle of the attractive force F1 generated as the feedback force. In a state where the direction key 40 is tilted, a reaction force of a restoring force (attraction force) by the permanent magnet 10 and the core 20 is applied to the fingertip of the operator. At this time, a voltage is applied to the coil 70 disposed around the core 20, and a current flows through the coil 70. For example, when a current is passed in the direction shown in FIG. 10, the direction of the magnetic field H1 generated by the end face magnetized permanent magnet 10 and the direction of the magnetic field H2 generated by the coil 70 are substantially the same. The force for attracting the magnet 10 is stronger than in a state where no current is passed through the coil 70. Therefore, the magnitude of the upward reaction force applied to the fingertip of the operator increases, and the change in the increased force is transmitted to the operator. This changing force is used as a feedback force. The waveform of the current flowing through the coil 70 may be a direct current or a rectangular wave. Moreover, a sine wave, a triangular wave, and a sawtooth wave may be sufficient.

  FIG. 11 is a diagram for explaining the generation principle of the repulsive force F2 generated as the feedback force. A voltage is applied to the coil 70 disposed around the core 20 in the direction opposite to that shown in FIG. Then, since the current flows in the direction shown in FIG. 11, the direction of the magnetic field H1 generated by the end face magnetized permanent magnet 10 and the direction of the magnetic field H2 generated by the coil 70 are substantially opposite. A repulsive force is generated between the magnet 10 and the coil 70 (core 20). Accordingly, the magnitude of the upward reaction force applied to the fingertip of the operator is reduced, and the change in the reduced force is transmitted to the operator. This changing force is used as a feedback force. As above, the waveform of the current flowing through the coil 70 may be a direct current or a rectangular wave. Moreover, a sine wave, a triangular wave, and a sawtooth wave may be sufficient.

  Further, since the repulsive force F2 generated between the tilted permanent magnet 10 and the coil 70 (core 20) is not completely perpendicular to the XY plane, a direction parallel to the XY plane is generated. Deviation in direction. The lateral repulsive force F3 that shifts the permanent magnet 10 has an effect of giving the operator a feeling of stimulating the fingertip of the operator by friction between the fingertip of the operator and the direction key 40.

  Further, by alternately supplying currents in the directions shown in FIGS. 10 and 11 to the coil 70, it is possible to repeatedly increase the attractive force F1 and generate the repulsive force F2 to give a stimulus to the fingertip of the operator. Moreover, the magnitude | size of the attractive force F1, the repulsive force F2, and the lateral repulsive force F3 can be changed by changing the magnitude | size of the electric current sent through the coil 70. FIG. That is, if the current value of the current flowing through the coil 70 is increased, these forces can be increased, and if the current value is decreased, these forces can be decreased.

  FIG. 12 is a view showing a recess 33 for preventing the displacement of the permanent magnet 10. By providing the upper surface 31 of the substrate 30 with the recess 33 that is slightly larger than the diameter of the permanent magnet 10 (the direction key 40 and the permanent magnet 10 can be tilted), the positional displacement of the permanent magnet 10 can be prevented. .

  FIG. 13 is a view showing a sheet 34 for preventing the displacement of the permanent magnet 10. A mat-like sheet 34 (for example, a rubber sheet) having a high coefficient of friction that does not cause displacement of the permanent magnet 10 is fixed to the upper surface 31 of the substrate 30. Thereby, the shift | offset | difference of the fulcrum position of the permanent magnet 10 can be prevented.

  FIG. 14 is an exploded perspective view of the operation input device 2 according to the second embodiment of the present invention. FIG. 15 is a cross-sectional view of the operation input device 2 in an initial position state where no operation input is applied. The description of the same parts as those in the above embodiment is omitted.

In general, an inductance L of an inductor such as a coil (winding) has a coefficient K, a permeability μ, a coil winding number n, a cross-sectional area S, and a magnetic path length d.
L = Kμn ² S / d
The following relational expression holds. As is clear from this relational expression, when parameters depending on the shape such as the number of turns of the coil and the cross-sectional area are fixed, the inductance changes depending on whether at least one of the surrounding magnetic permeability and the magnetic path length is changed.

  The operation input device 2 detects the inductance of the coil installed on the substrate 30 so as to face the yoke installed on the direction key 40, thereby determining the stroke amount when the direction key 40 is displaced downward by the operation input. It is something that can be detected.

  That is, in the operation input device 2, the conductive pattern of the operation input device 1 is replaced with a coil, and the conductive pad of the operation input device 1 is replaced with a yoke. The conductive pattern of the operation input device 1 may be replaced with a yoke, and the conductive pad of the operation input device 1 may be replaced with a coil. FIG. 14 shows coils 91a to 94a and yokes 91b to 94b. The yoke may be made of a material having a relative permeability higher than 1. For example, the relative magnetic permeability is preferably 1.001 or more, specifically, a steel plate (relative magnetic permeability 5000) or the like is preferable. The yoke can be integrated with ferrite or the like instead of being separated from the direction key 40. The substrate 30 is a non-magnetic substrate made of resin. When the direction key 40 tilts and the yoke approaches the coil, the magnetic permeability around the coil increases and the inductance of the coil increases. By electrically detecting this, the tilting operation of the direction key 40 can be detected.

  That is, when the operation key 41 on the X (+) direction side of the direction key 40 is pressed (FIG. 18), the yoke 91b changes in the direction in which the inductance of the coil 91a increases as the yoke 91b approaches the coil 91a. Changes in the direction in which the inductance of the coil 93a decreases as the distance from the coil 93a increases. Therefore, by measuring the correspondence between the tilt amount of the direction key 40 and the inductance of each coil in advance, the predetermined operation input detection device corresponds to the measured inductance according to the correspondence measured in advance. The amount of tilt of the direction key 40 can be detected. Thereby, it is also possible to generate a feedback force corresponding to the tilt amount (analog amount) of the direction key 40 by adjusting the current flowing through the coil 70 based on the tilt amount (analog amount) of the direction key 40. .

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-described embodiments, and various modifications, improvements, and modifications can be made to the above-described embodiments without departing from the scope of the present invention. Substitutions can be added. In addition, another embodiment configured by combining a part of each of the plurality of embodiments described above may be considered.

  For example, the permanent magnet 10 is illustrated as the first magnetic body disposed on the base of the nonmagnetic material, and the core 20 is illustrated as the second magnetic body on the opposite side of the first magnetic body with the base interposed therebetween. In this regard, in order to generate a magnetic force that brings the first magnetic body into contact with the base between the first magnetic body and the second magnetic body, at least of the first magnetic body and the second magnetic body. As long as one side is magnetized, the second magnetic body may be magnetized without the first magnetic body being magnetized, or both magnetic bodies may be magnetized. . Further, a coil may be wound around the first magnetic body so that a change in the magnetic field can be caused to function as an electromagnet as a whole.

  19 and 20 show other embodiments of the first magnetic body. The surface of the permanent magnet 110 facing the substrate 30 (that is, the lower surface 112) is a spherical surface. Since the lower surface 112 of the permanent magnet 110 is in close contact with the upper surface 31 of the substrate 30 by the attractive force F generated by the magnetic force generated between the permanent magnet 110 fixed to the lower surface 43 and the core 20, the direction key 40 is always in the substrate 30. Is maintained parallel to Since the lower surface 112 is a spherical surface, the permanent magnet 110 and the substrate 30 are in contact with each other at a contact point D. Then, as shown in FIG. 20, a point E on the X-axis positive side arc of the lower surface 112 of the permanent magnet 110 (that is, the lower surface 112 is on the upper surface 31 of the substrate 30 on the X (+) direction side with respect to the axis S). The direction key 40 tilts together with the permanent magnet 110 with the contact portion) as a fulcrum.

  Thus, since the direction key 40 tilts together with the permanent magnet 110 with the contact E on the operation point side of the operation input as a fulcrum with respect to the center of the lower surface 112, not only as a force for bringing the permanent magnet 110 into contact with the substrate 30, The suction force F can be used as a force that resists the tilting of the direction key 40 in the direction away from the core 20. That is, the automatic origin return mechanism that returns the direction key 40 tilted by the operation input on the X (+) direction side to the initial position state of FIG. 19 is realized with a simple configuration.

  In addition, the shape of the portion where the first magnetic body is opposed to the base portion of the non-magnetic body is a circle in the above-described embodiment, but may be a polygon such as a quadrangle or an octagon. In this case, the direction key tilts together with the first magnetic body with the side of the polygon as a fulcrum. The shape of the portion where the first magnetic body faces the base of the non-magnetic body may be concave. In this case, the concave contour contacts the base, and the direction key tilts together with the first magnetic body with the point on the contour as a fulcrum.

  Moreover, although the disk-shaped direction key 40 was illustrated as an operation part which receives operation input, an input direction is not restricted to 4 directions. The operation unit may be operable in any direction of 360 °.

  In addition, the configuration in which the tilt of the direction key 40 is detected by detecting contact between the conductive pad and the conductive pattern and the configuration in which the tilt of the direction key 40 is detected by detecting a change in inductance are exemplified. The configuration of the detection unit that detects the tilt of 40 is not limited to these configurations. For example, the amount of tilt of the direction key 40 is detected by detecting a change in electrostatic capacitance between the movable electrode fixed to the lower surface 43 of the direction key 40 and the fixed electrode fixed to the upper surface 31 of the substrate 30. It may be configured.

  Further, the operation input device is not limited to fingers and may be operated with a palm. Moreover, you may operate with a toe or a sole. The surface touched by the operator may be a flat surface, a concave surface, or a convex surface.
