Description

  As an input device using a conventional acceleration sensor or angular velocity sensor, a device that detects movement in the X and Y directions perpendicular to the Z direction as the vertical direction and is used as a character input means or a pointing device has been proposed. ing. For example, it has a pen shape, and when a user writes a character with a pen, it is used for character input, or it has a long and narrow cylindrical shape, and one of them is pointed in the direction you want to point and shakes it up, down, left, or right The movement is detected and used as a pointing device.

  Examples of such pen-type input devices used in conventional computers and the like are disclosed in Patent Document 1 and Patent Document 2. Patent Document 1 describes a pen-type computer input device used for handwritten character input and two-dimensional coordinate input of a computer. This pen-type computer input device includes two acceleration sensors that detect accelerations in two orthogonal directions in a plane, an acceleration detection circuit and an integration circuit that convert a signal from the acceleration sensor into a movement amount in the plane, , A piezoelectric vibration gyro which is a rotation detecting means, an angular acceleration detection circuit which detects a signal from the piezoelectric vibration gyro and converts it into a rotation correction signal, an integration circuit, and a correction circuit.

  However, when a conventional accelerometer or angular velocity sensor is fixed inside an elongated cylindrical housing, for example, in the case of a pen type, correction is required when the pen axis is inclined from the vertical direction. Since the inclination of the pen axis varies depending on the person who performs it, individual correction for this is also necessary. In addition, when there is rotation of the case around the pen axis, the acceleration sensor and angular velocity sensor also rotate with the case, so the actual writing trajectory and the extracted trajectory are displaced due to the rotation. Correction was also necessary.

  Further, since the pen-type computer input device disclosed in Patent Document 1 is based on the premise that the pen is used in a vertical state, the influence of the rotation of the pen shaft can be corrected. There is a disadvantage that it cannot be corrected for input with the pen shaft tilted.

  Further, the pen-type input device disclosed in Patent Document 2 can correct both the tilt and rotation of the pen axis. However, since an acceleration sensor and an angular velocity sensor are also required in the Z-axis direction, the cost increases. Furthermore, there is a disadvantage that the configuration of the correction process becomes complicated.

  In view of this point, the present invention provides an input device having a simple configuration capable of obtaining a good detection result without correction processing even if the input device is rotated around the axis and tilted. The purpose is to provide.

  An input device of the present invention includes a first detector that detects movement in a first direction, and a second detector that detects movement in a second direction, and an output of the first detector; A locus is extracted from the output of the second detector, and a detector holding body is provided so that the postures of the first detector and the second detector are always substantially the same. .

  According to the input device of the present invention configured as described above, the first detector and the second detector provided integrally are always substantially the same even when there is rotation and inclination around the axis of the input device. The first detector and the second detector can be supported in a posture.

According to the present invention, in the input device described above, the detector holder is rotated by an annular component that is rotatably provided around an axis in the input device, and a support that is provided on the annular component. It consists of a first detector and a second detector which are suspended in a movable manner and are integrally arranged orthogonally.

  According to the input device of the present invention configured as above, the center of gravity of the detector holder is at the lowest position, the support is substantially horizontal, and the center of gravity of the detector holder is arranged on the vertical surface of the support. When the input device is tilted or rotated around its axis from this stable state, the annular part is input so that the center of gravity of the detector holder matches the vertical surface of the support. Since the detector holding body provided with the first detector of acceleration and the second detector of acceleration is rotated around the support body while rotating with respect to the outer casing of the apparatus, the pen When an input device is moved and moved on a substantially horizontal plane with the input device held in a substantially constant orientation, the acceleration will be applied even if the rotation or tilt changes around the axis of the outer casing due to hand handling. The first detector and the second detector of acceleration have a substantially constant posture in the vertical direction. Can Unisuru.

  According to the present invention, in the input device described above, the detector holder is provided with an annular component that is rotatable about an axis in the input device, and a first support provided on the annular component. A first body that is rotatably supported by a body in a vertical plane, is rotatably suspended in a horizontal plane by a second support body that is provided so as to be orthogonal to the first support body, and is disposed orthogonally. These detectors, the second detector, and the azimuth magnet are integrally provided.

  According to the input device of the present invention thus configured, the center of gravity of the detector holder is at the lowest position, the first support is substantially horizontal, and the center axis of the second support is substantially vertical. Since the state that passes through the center of gravity of the orientation detector holder is stable, when the input device is tilted or rotated around its axis from this stable state, the center of gravity of the detector holder deviates from the lowest position. The annular component rotates with respect to the outer casing of the input device, and a detector holding body provided with a first detector for acceleration and a second detector for acceleration is disposed around the first support. The center of gravity can be rotated to the lowest position, and at the same time, the detector holder can be rotated around the second support by the azimuth magnet and the geomagnetism so as to face a predetermined direction. The first detector of acceleration and the second detector of acceleration are always substantially constant in the vertical and horizontal directions. It can be made to be.

  Further, according to the present invention, in the input device described above, the output of the first detector and the output of the second detector are wirelessly transmitted to an electronic device having a display screen.

  According to the input device of the present invention configured as described above, the input device is configured to be a pen-type, small and light, and used as a pointing device or a character input means while looking at the display screen of the electronic device from a distance. The operation can be performed.

  The input device according to the present invention allows the first detector of acceleration and the second detector of acceleration to be always kept in a constant posture even if there is a change in gripping state due to operation or hand handling. It is not necessary to correct this signal, and the deviation between the actual locus and the detection result can be hardly caused with a simple configuration.

An example of the best mode for carrying out the input device of the present invention will be described below with reference to FIGS.
The input device of this example is of a pen type as shown in FIG. 5. The pen type input device is gripped and operated to move in a substantially horizontal plane, and as shown in FIG. A signal that accompanies the movement of the input device is wirelessly sent to a receiver built in a display device 50 having a large screen, such as a plasma display or a projection display shown in the figure, and the display screen 51 is viewed on the screen. The cursor can be moved between the menus 52 and characters can be input to the character input field with this single input device.

FIG. 1 is an enlarged view of a part of the input device shown in FIG.
In FIG. 1, reference numeral 1 denotes a pen-shaped grip body made of a synthetic resin material such as plastic, and a detector holding supported by a bearing and two support bodies inside the grip body 1 near a substantially conical portion at the tip. A body 10 is provided.
The bearing is composed of an outer ring 2, a rolling ball, and an inner ring 4. As shown in FIG. 1, the outer ring 2 is fixed in the gripping body 1, and a plurality of balls serving as rolling elements inside the outer ring 2. The inner ring 4 is rotatably engaged via the.

The inner ring 4 is rotatably provided with a first support made of a shaft 3a having a circular cross section so as not to pass through the center of the inner ring 4. The shaft body 3a is provided with one end of a shaft 3b which is a second support body so as to be substantially orthogonal to the shaft body 3a at the approximate center thereof. The other end of the shaft 3b is rotatably provided with the detector holder 10.
The shaft body 3a and the shaft 3b are fixed so that the center of each shaft is substantially orthogonal at a point S shown in FIG.

The detector holder 10 includes a casing 7 provided with movement detectors (acceleration sensors) 5 and 6, a weight 8, magnets 9a and 9b, and the like.
As shown in FIG. 1, the housing 7 is a substantially quadrangular columnar shape made of nonmagnetic metal or hard plastic, and has two rectangular side surfaces on the two opposite side surfaces on the upper end side in the longitudinal direction. The magnets 9a and 9b for the direction are attached. That is, the south pole of the magnet 9a is exposed on one side and the north pole of the magnet 9b is exposed on the other end side.

  A detector for detecting movement in the X direction and the Y direction is provided on the side surface on the lower end side of the housing 7. That is, as shown in FIG. 1, for example, the acceleration sensor 5 in the X direction is provided on the same surface as the magnet 9a, and the acceleration sensor 6 in the Y direction is provided on a surface orthogonal to the acceleration sensor 5 in the X direction. A weight 8 is fixed to the lower surface of the casing 7 in the longitudinal direction.

Further, a hole 7a in which a small diameter bearing (not shown) is embedded is provided on the upper surface of the housing 7, and the center axis of the hole 7a passes through the center of the small diameter bearing, and the acceleration sensors 5, 6, magnets 9a, 9b, weight 8 Is formed so as to pass through the center of gravity (hereinafter referred to as the center of gravity G) of the housing 7 provided with.
And the housing | casing 7 is rotatably supported around the axis | shaft of the axis | shaft 3b, when the axis | shaft 3b engages with this small diameter bearing rotatably.

  The magnets 9a and 9b for the orientation of the detector holder 10 shown in FIG. 1 may be provided in the housing 7 as a single bar shape instead of being separated. Therefore, it is desirable to magnetically connect the N pole of the magnet 9a and the S pole of the magnet 9b with a magnetic material. The weight 8 of the housing 7 is made of a nonmagnetic metal or the like having a large specific gravity. The center of gravity of the housing 7 provided with the acceleration sensors 5 and 6 is further away from the shaft body 3a. The vibration period (of operation) is further increased, and the rotational moment is increased so that smooth rotation around the shaft body 3a and the inner ring 4 is realized.

  Since the detector holder 10 is configured and supported as described above, the center of gravity G of the detector holder 10 is the lowest position in the tilted grip body 1, and the center of gravity G is a fixed point shown in FIG. The state arranged on the vertical line of S is the most stable posture. At this time, the shaft body 3a is substantially horizontal and the shaft 3b is oriented substantially vertically.

  When the gripping body 1 rotates about its axis and deviates from this stable posture, the inner ring 4 rotates with respect to the outer ring 2 so that the center of gravity G is at the lowest position, and the shaft body 3a is substantially horizontal. In addition, when the gripping body 1 changes its inclination with respect to its axis and deviates from this stable posture, the center of gravity G of the detector holder 10 is positioned at the lowest position with respect to the inner ring 4. The shaft body 3a rotates, and the center of gravity G of the detector holder 10 is arranged on the vertical line of the fixed point S.

  At this time, the orientation with respect to the orientation of the detector holder 10 itself is such that the magnet holder 9a exposes the south pole on one side of the detector holder 10 and the north pole on the opposite side. Since the magnet 9b is provided and is rotatable with respect to the shaft 3b, the side surface on which the magnet 9b of the detector holder 10 is provided always faces the magnetic north pole by geomagnetism and maintains a constant posture.

Further, as shown in FIG. 5, the gripping body 1 is provided with a signal processing circuit 11 on the opposite side of the tip end portion of the gripping body 1 where the detector holding body 10 is provided, and detected by the acceleration sensors 5 and 6. The acceleration signal is converted into a movement signal and transmitted to the electronic device wirelessly via the antenna 12. FIG. 2 is a block diagram showing an example of the configuration of the signal processing circuit 11 and the output system to the electronic device.
Note that the detector holder 10 of the present example is always maintained in a constant posture with respect to the geomagnetism as described above, so that it is not necessary to mount an electric circuit for performing posture control, and the circuit configuration is simplified. ing.

In FIG. 2, 15 is an acceleration detection circuit that detects acceleration signals output from the acceleration sensor 5 in the X direction and the acceleration sensor 6 in the Y direction, and 16 is an integration circuit that converts the acceleration signal into a speed signal. The acceleration detection circuit 15 and the integration circuit 16 constitute movement amount calculation means for detecting the movement amount of the input device. The voltage value obtained by the integration circuit 16 is converted into a frequency corresponding to the amount of movement by a voltage / frequency (V / F) conversion circuit 17 in the next stage. Here, since the frequency corresponds to the amount of movement, the frequency changes every moment with the operation of the input device.
Reference numeral 18 denotes a direction discriminating circuit for discriminating the moving directions of the X and Y acceleration sensors 5 and 6 from the acceleration signal input from the acceleration detection circuit 15. Reference numeral 19 denotes a modulation circuit for modulating the carrier wave by the movement direction and movement amount signals input from the direction discrimination circuit 18 and the voltage / frequency conversion circuit 17, and 20 denotes the output of the modulation circuit 19 to the electronic device via the antenna 12. A transmission circuit for transmitting wirelessly.

The operation of the input device in the example shown in FIGS. 1 and 2 will be described with reference to FIGS.
FIG. 3 shows the state of the detector holder 10 when the gripping body 1 shown in FIG. 1 is tilted and the tip is placed on a flat surface. FIG. 3A shows a part of FIG. FIG. 3B is a schematic view with a part cut away when FIG. 3A is viewed from above.
FIG. 4 shows a state in which the tip of the gripping body 1 is kept in contact with a point O on the surface and is moved around a vertical line with its axis tilted like a precession of the top, FIG. FIG. 4B is a schematic view as seen from above, and FIG.
3 and 4, the magnetic north pole is on the right side of the figure.

  For this reason, the gripper 1 is shown in FIG. 4A when its axis L changes its inclination in the vertical plane as shown in FIG. 3A, or as shown in FIG. 4B at positions (A) to (E). When the axis L is moved around the point O in a tilted state, the surface of the gripper 1 where the magnet 9b of the detector holder 10 is arranged and the N pole is exposed is always the right side shown in the figure. Toward the magnetic north pole, the center of gravity G of the detector holder 10 is in the lowest position so as to be in the most stable posture.

In this stable state, as shown in FIG. 3A, a vertical line passing through the center of gravity G is defined as the Z axis, the center of gravity G is the origin, the axial direction of the shaft body 3a is the Y axis, and the Y axis is orthogonal to the Z axis. The right magnetic north pole direction shown in the figure is defined as the X axis. At this time, the fixed point S (see FIG. 1) between the shaft 3b and the shaft body 3a is disposed substantially on the Z-axis.
That is, in FIG. 3, the axis L of the gripping body 1 shown in FIG. 3A is the axis L ′ in the projection onto the horizontal plane shown in FIG. 3B, and this axis L ′ is orthogonal to the axis 3a. The axis L ′ is substantially oriented to the magnetic north pole and parallel to the X axis, and is orthogonal to the Y axis.

Hereinafter, the movement of the detector holder 10 according to the operation of the grip body 1 will be described.
First, a case where the gripping body 1 is operated with its axis L as it is will be described.
When the inclination of the axis L shown in FIG. 3A is simply changed in the vertical direction, the shaft body 3a is maintained in a constant positional relationship with respect to the geomagnetism of the X-direction acceleration sensor 5 and the Y-direction acceleration sensor 6 with respect to the coordinate axis Z. Rotate. That is, the detector holder 10 remains in a certain direction.
3A and 3B, the positional relationship of the acceleration sensor 5 in the X direction with respect to the coordinate axis Z and the geomagnetic field of the acceleration sensor 6 in the Y direction is kept constant when the gripping body 1 rotates around the axis L. The shaft body 3 a rotates while rotating with respect to the shaft 3 b so that a stable state is achieved, and at the same time, the inner ring 4 rotates with respect to the outer ring 2.

Next, a case where the gripper 1 is operated so as to change its axis L in space will be described.
As shown in FIG. 4B, when the inclination of the axis L changes while the gripper 1 moves around a perpendicular line from the tip, the acceleration sensor 5 in the X direction with respect to the coordinate axis Z and the acceleration sensor 6 in the Y direction The detector holder 10 is rotated around the shaft 3b so that the positional relationship with respect to the geomagnetism is kept constant, and the inner ring 4 and the shaft 3a are rotated with respect to the outer ring 2.
Also, when the gripping body 1 rotates around the axis L while moving around the vertical line from the tip, or when the rotation and inclination around the axis L are changed while moving around the vertical line from the tip. The detector holder 10 rotates around the shaft 3b and the inner ring relative to the outer ring 2 so as to keep the positional relationship of the acceleration sensor 5 in the X direction with respect to the coordinate axis Z and the geomagnetic field of the acceleration sensor 6 in the Y direction constant. 4 and the shaft 3a are rotated.

That is, the rotation of the gripper 1 about the axis L, the change in the tilt of the axis L, the movement of the axis L about the vertical line, or a combination of these operations is performed on the input device, and the detector holder 10 When an operation is performed so that the center of gravity G deviates from a stable position, the rotation of the inner ring 4 with respect to the outer ring 2, the rotation of the shaft body 3a with respect to the inner ring 4, and the rotation of the detector holder 10 with respect to the shaft 3b are always performed. The center of gravity G of the detector holding body 10 can be brought into a stable state in the lowest position while the surface of the detector holding body 10 on which the magnet 9b is provided faces the magnetic north pole.
Regardless of the posture of the gripper 1, the detector holder 10 is translated without rotating with respect to the XYZ coordinate system so that it always faces the same direction, and the acceleration sensor 5 in the X direction is in the XZ plane. It is possible to always maintain a positional relationship in which the acceleration sensor 6 in the Y direction is parallel to the YZ plane.

When the input device is moved in an arbitrary direction by a writing operation, the signal processing device 11 has a response corresponding to the acceleration received by the acceleration sensor 5 in the X direction and the acceleration sensor 6 in the Y direction provided in the housing 1 shown in FIG. As shown in FIG. 2, an acceleration signal is output from the acceleration detection circuit 15.
This acceleration signal is input to the direction discriminating circuit 18 and the moving direction of the housing 1 is obtained. At the same time, the voltage / frequency converting circuit 17 converts the moving signal into a frequency according to the moving amount via the integrating circuit 16. In addition, when the moving amount | distance of the holding body 1 is large, a voltage becomes high and the converted frequency becomes high.

As shown in FIG. 2, the movement direction signal output from the direction discrimination circuit 18 and the frequency signal corresponding to the movement amount output from the voltage / frequency conversion circuit 17 are input to the modulation circuit 19.
The modulation circuit 19 switches the frequency signal generated with the movement of the gripper 1 in the writing operation to positive and negative based on the output of the direction discriminating circuit 18, while the carrier wave is generated by the movement direction and movement amount signals. Modulated. The output from the modulation circuit 19 is wirelessly transmitted to the electronic device via the oscillation circuit 20 and the antenna 12, demodulated in the built-in receiver, and the drawing coordinates at the substantially distal end portion of the grasping body 1 are sequentially obtained. And the trajectory is displayed on the screen.

  In the process of signal processing accompanying the above movement of the gripping body 1, the center of gravity G of the detector holder 10 is always at the lowest position by the rotation of the inner ring 4 of the bearing, the shaft body 3a, and the shaft 3b. Therefore, even if there is a rotation around the axis L of the gripper 1, a change in the inclination of the axis L, and a movement around the perpendicular of the axis L, these changes in the attitude Since no detection means is required, the electrical signal processing system can be made extremely simple.

Then, for example, with the input device shown in FIG. 5 turned on, a start switch (not shown) is turned on, the position information of the input device at this time is reset and the coordinate origin is designated, and then characters, figures, etc. are displayed. When drawing, even if the gripping body 1 is rotated with respect to the tip or rotated around the axis L, the detector holder 10 is always maintained in a fixed posture. Changes in the electrical resistance values of the acceleration sensor 5 in the X direction and the acceleration sensor 6 in the Y direction accompanying the movement of the signal can be sequentially converted into signals of the movement direction and the movement amount by the signal processing circuit 11 and output.
When the acceleration sensor 5 in the X direction and the acceleration sensor 6 in the Y direction are fixed to the grasping body 1, a large deviation occurs between the actual locus and the detection result. Thus, no error occurs between the locus projected on the surface (horizontal plane) perpendicular to the vertical line direction of the actually drawn locus and the locus obtained from the detection outputs of the acceleration sensors 5 and 6.

  According to the input device of this example, the surface of the detector holder 10 on which the magnet 9b on which the north pole is exposed is directed to the magnetic north pole, and the center of gravity G of the detector holder 10 is in the lowest position. Even if the detector body 10 is shifted from this stable state by rotating the gripping body 1 around the axis L, changing the inclination, or moving it around the vertical line, the original stable state can be obtained. The acceleration sensor 5 and the acceleration sensor 6 are always kept in a constant posture in the horizontal and vertical directions regardless of the change in the posture of the pen-shaped gripping body 1 due to operation or handling, and the X direction. Thus, the acceleration in the Y direction can be detected, and the actual trajectory and the detection result can be detected without any deviation.

  In the above-described example, the support for the detector holder 10 has been described as having a rod-like shaft body 3a that is rotatably provided on the inner ring 4 of the bearing and a shaft 3b that is fixed to the shaft body 3a. Although the conditions of use are limited, more simply, as shown in FIG. 7, the detector holder 10 is supported by the shaft body 3a rotatably provided on the inner ring without providing the shaft 3b and the magnet for orientation. You may do it. The input device with this simple configuration is an operation that faces the desk, for example, on a chair so that the gripper 1 itself does not move around the vertical line from the tip and the posture of the input device is almost constant during the input operation. It can be used when a person holds the input device and performs an input operation.

Further, in the above-described example, the shaft body 3a and the shaft 3b are described as being rigid. However, instead of this, a wire such as a nonmagnetic metal is used, and the rotatable engagement of the detector holding body 10 is simpler. Of course, it may be done. Further, in order to realize smooth rotation of the inner ring 4 and the detector holder 10, a bearing (outer ring 2, rolling ball, inner ring 4), detector in a liquid having a small viscosity, insulating and non-corrosive. A structure in which the holding body 10 (acceleration sensors 5 and 6, weight 8, magnets 9a and 9b) and the like are immersed and sealed may be employed.
Further, an electromagnet may be used as the magnet instead of the permanent magnet.

  Further, in this example, the output example of the case where the output of the input device is sent by the display device 50 wirelessly separated via the antenna 12 (see FIG. 6) has been described. Of course, it may be a means for sending a signal from the apparatus, and of course, it may be connected to an electronic device with a cable in order to exhibit the function of this input apparatus.

  In addition, the input device of the present invention is not limited to the above-described example, and can of course adopt various configurations without departing from the gist of the present invention.
