  However, the pointing device has a narrow range in which the position information input unit (operation unit) can be slid. Thus, if the movable range of the operation unit is narrow, the pointer on the display moves quickly only by moving the operation unit a little, so that it is difficult to perform an accurate position designation operation. Therefore, an input device including an operation unit that moves within a wide range to some extent is preferable.

  ADVANTAGE OF THE INVENTION According to this invention, the input apparatus provided with the structure which hold | maintains an operation part stably when not performing input operation can be provided.

  Embodiments of an input device according to the present invention will be described below with reference to the drawings.

  The input device M according to the first embodiment includes a position detection unit D that can accurately detect the position of the operation unit with a simple configuration. First, the position detection unit D will be described. FIG. 1 is an enlarged view of the configuration of the position detection unit D provided in the input device M. The position detection unit D is formed to include at least a magnet 1 and an electromagnetic conversion element 3 serving as magnetic field generating means. The electromagnetic conversion element 3 is disposed so as to be located in a predetermined plane. For example, as shown in FIG. 1, when three axes A, B, and C that are orthogonal to each other are assumed, the electromagnetic transducer 3 is disposed so as to exist in an AB plane that is at a fixed position in the C-axis direction. The magnet 1 is disposed so as to face one side of the electromagnetic transducer 3 in a direction orthogonal to the AB plane. A surface 2 of the magnet 1 facing the electromagnetic conversion element 3 (hereinafter referred to as an opposing surface 2) is a flat surface that is inclined linearly. More specifically, the magnet 1 has a rectangular shape when projected onto the AB plane, and the longitudinal direction is arranged parallel to the A-axis direction. The facing surface 2 is an inclined surface that is linearly inclined in the A-axis direction. In this structure, the distance between the magnet 1 and the electromagnetic transducer 3 changes approximately linearly. The magnet 1 shown in FIG. 1 has a thickness that changes sequentially in the A-axis direction (thickness in the C-axis direction). A magnetic field MA perpendicular to the AB plane is generated from the facing surface 2 toward the electromagnetic transducer 3.

  In FIG. 1, a quadrangular prism-shaped yoke 5 is disposed on the upper side (opposite side of the magnet 1) of the electromagnetic transducer 3 as a more preferable configuration. The yoke 5 is disposed so as to face the magnet 1 with the electromagnetic conversion element 3 in between. The yoke 5 is arranged in parallel with the electromagnetic transducer 3, that is, the lower surface 6 of the yoke 5 is arranged in parallel with the AB plane. The yoke 5 functions to induce the magnetic field MA so that the magnetic field MA is oriented perpendicular to the electromagnetic transducer 3. Hereinafter, the yoke 5 is referred to as the induction yoke 5.

  As a preferred structure, a quadrangular prism-shaped yoke 4 is connected to the bottom surface of the magnet 1. The yoke 4 functions to suppress the leakage magnetic field of the magnet 1. As shown in FIG. 1, it is more effective to arrange the yoke 4 in contact with the bottom surface of the magnet 1, but the yoke 4 may be disposed away from the bottom surface. The magnet 1 may be a permanent magnet or an electromagnet. As the electromagnetic conversion element 3, a Hall element, a magnetoresistive effect element (MR element) or the like can be adopted.

  When the magnet 1 and the electromagnetic conversion element 3 shown in FIG. 1 are relatively moved in the A-axis direction, the electromagnetic conversion element 3 outputs a signal (voltage corresponding to the strength of the magnetic field). The electromagnetic conversion element 3 may be fixed and the magnet 1 may be moved in the A-axis direction, or the magnet 1 may be fixed and the electromagnetic conversion element 3 may be moved in the A-axis direction. FIG. 2 is a diagram schematically showing a state when the electromagnetic conversion element 3 is moved. (A) -1 shows the time when the electromagnetic conversion element 3 is on the left side narrow between the induction yoke 5 and the facing surface 2, and (B) -1 shows that the electromagnetic conversion element 3 is between the induction yoke 5 and the facing surface 2. It shows when the gap is on the wide right side. (A) -2 is a side view corresponding to (A) -1, and (B) -2 is a side view corresponding to (B) -1.

  In the state shown in FIG. 2A, the magnetic field received by the electromagnetic conversion element 3 is large (the magnetic flux density is high). Conversely, in the state shown in FIG. Small (low magnetic flux density). The magnetic field between the induction yoke 5 and the opposing surface 2 changes continuously as shown in FIG. Therefore, a linear output signal can be obtained from the electromagnetic conversion element 3 when the electromagnetic conversion element 3 moves in the position range shown in FIGS. 2 (A) and 2 (B). Therefore, the position of the electromagnetic conversion element 3 in the A-axis direction can be detected based on this output signal. In the input device M, the position detection unit D having the above-described configuration is disposed on each of two orthogonal axes.

  FIG. 4 is a perspective view showing the appearance of the input device M. FIG. 5 is an exploded perspective view of the apparatus M, and FIG. 6 is a view showing a front view and a right side view together with a plan view of the apparatus M. The input device M shown in these drawings includes two position detection units D shown in FIG. In order to omit redundant description, the same parts as those shown in FIG. In addition, since two position detectors D are included, branch numbers (-1, -2) are attached for distinction. In FIG. 4, two orthogonal axes X and Y are virtually used for the description.

  In the input device M, a mechanical structure is assembled on the printed circuit board 10. The input device includes a first slider 20 that is movable in the X-axis direction and a second slider 30 that is movable in the Y-axis direction. The first slider 20 is guided by rails 12 provided on the side wall 11 parallel to the X axis provided on the side of the housing 8 disposed on the substrate 10, and the second slider 30 is provided on the side of the housing 8. It is guided by a rail 14 provided on a side wall 13 parallel to the Y axis.

  The first slider 20 has a rectangular shape, and includes a long hole 21 formed at the center and a support frame 22 provided so as to protrude to one end side. In the elongated hole 21, an operation unit 40 is fitted as a moving body. An operation projection 41 is provided on the operation unit 40. The operator can move the operation unit 40 to a desired position using the protrusion 41. The support frame 22 supports the magnet 1-1, the yoke 4-1, and the induction yoke 5-1 that constitute the first position detection unit D-1. The electromagnetic transducer 3-1 located between the magnet 1-1 and the induction yoke 5-1 is fixed at a predetermined position on the substrate 10 as shown in FIG. The facing surface 2-1 of the magnet 1-1 is linearly inclined in the X-axis direction in which the first slider 20 moves. More specifically, the thickness of the magnet 1-1 decreases from the left side to the right side on the X axis.

  The second slider 30 is placed orthogonally on the first slider 20. The second slider 30 is formed in the same manner as the first slider 20. That is, it includes a long hole 31 formed in the central portion and a support frame 32 provided so as to protrude to one end side. The operation unit 40 is fitted in the long hole 31. The support frame 32 supports the magnet 1-2, the yoke 4-2, and the induction yoke 5-2 that constitute the second position detection unit D-2. The electromagnetic conversion element 3-2 positioned between the magnet 1-2 and the induction yoke 5-2 is fixed at a predetermined position on the substrate 10.

  The operation unit 40 is fitted in the long hole 21 of the first slider 20 and the long hole 31 of the second slider 30. Therefore, when the operator moves the operation unit 40, the first slider 20 and the second slider 30 move, and the magnet 1-1 moves in the X-axis direction and the magnet 1-2 moves in the Y-axis direction. Accordingly, an output signal corresponding to the moving position is output from the electromagnetic conversion element 3-1 and the electromagnetic conversion element 3-2 arranged on each axis. Therefore, the position of the operation unit 40 in the XY plane can be detected.

  Further, the input device M has a structure for stably holding the operation unit (moving body) 40 when an input operation is not performed (when not used). Hereinafter, this point will be further described. As can be seen in FIGS. 4 and 5, the operation unit 40 is formed of a plurality of parts. The operation unit 40 includes a rectangular parallelepiped block 43 as a main body. A cutout 44 is provided in the block 43, and a chip component 45 is fitted into the cutout 44. The chip component 45 is a sliding member for smoothing the operation of the operation unit 40 that reciprocates in the long holes 21 and 31 in the sliders 20 and 30.

  The operation unit 40 is provided with spring members 47 and 48 that act to press the chip component 45 against the inner walls of the sliders 20 and 30. As can be seen in FIGS. 4 and 5, the spring member 47 abuts against the inner wall of the elongated hole 21 of the first slider 20 and urges the operating portion 40 in the Y-axis direction. Similarly, the spring member 48 abuts against the inner wall of the elongated hole 31 of the second slider 30 and biases the operation unit 40 in the Y-axis direction. In the assembled state shown in FIG. 4, the spring member 47 is hidden under the upper member.

  As described above, when the spring members 47 and 48 are arranged between the operation unit 40 and the sliders 20 and 30 that hold the operation unit 40 in a reciprocating manner, the operation unit 40 and the inner walls of the sliders 20 and 30 are arranged. A frictional force can be generated during this period. This frictional force is set so as to prevent an excessive load or operation during operation by the operator and prevent the moving body from moving when the input device is moved when not in use. Therefore, it is possible to realize a structure in which the operation unit 40 can be moved smoothly during an input operation and the operation unit 40 is held at a fixed position when no operation is performed. The spring members 47 and 48 may be appropriately selected to have a spring pressure capable of obtaining a desired frictional force. In the present embodiment, the spring members 47 and 48 serve as friction generating means as described above.

  FIG. 7 is a schematic diagram showing the spring member 48 disposed between the operation unit 40 and the long hole 31 of the second slider 30. The same applies to the relationship between the operating portion 40, the long hole 21 of the first slider 20, and the spring member 47. (A) has expanded and shown the form example of Example 1 mentioned above. The spring member 48 is a leaf spring that is bent in a mountain shape, and since both end portions 48a are supported at two points on the operation unit 40 side, a stable biasing force is generated, and the operation unit 40 and A frictional force can be generated between the two sliders 30. In addition, it is preferable to provide a space 40S on the periphery of the operation unit 40 that supports the spring member 48 so that the spring member 48 is easily deformed as illustrated in FIG. Thus, by providing the space 40S, the feeling of spring pressure can be adjusted.

  FIG. 7B shows an example of a case where the spring member 48 has a “<” shape and has a cantilever structure. FIG. 7C shows a modification of (A). The inner wall surface of the elongated hole 31 is formed to be uneven, and the top portion 48T of the spring member 48 formed in a mountain shape is engaged with the unevenness of the inner wall surface. With this structure, it is possible to generate a predetermined frictional force between the operation unit 40 and the inner wall of the slider 30 and to generate a click feeling. By generating a click feeling in this way, an operation feeling can be given to the operator who is performing the operation. Moreover, the operation part 40 can be reliably hold | maintained by a fixed position because the top part 48T makes a recessed part of an inner wall. FIG. 7D shows a structural example in the case where the friction generating means is configured by a coil spring 49 as a spring member and a pressing plate 50 as a pressing member biased by the coil spring 49. In this structure, since the pressing plate 50 is in wide contact with the inner wall of the slider 30, the operation unit 40 can be reliably held at a fixed position.

  In addition, although the example which has arrange | positioned the structure which generate | occur | produces a frictional force only in one side is shown in FIG. 7, you may arrange | position on both sides. Moreover, in the form which provides a spring member on both sides, it is good also as a structure which combined suitably the structure shown by (A)-(D).

  Furthermore, another structural example for holding the operation unit 40 of the input device M in a fixed position will be described. 4 to 6 again, the first slider 20 is guided by the rail 12 on the other hand as described above. The first slider 20 is slidably fitted to a guide shaft 25 (not shown in FIG. 5) disposed in the housing 8 on the other support frame 22 side. Similarly, the second slider 30 is slidably fitted to a guide shaft 35 disposed in the housing 8 on the support frame 32 side.

  In the first embodiment described above, the operation unit 40 is described as a moving body. However, the first slider 20 and the second slider 30 are held by the guide shafts 25 and 35 so as to be able to reciprocate. Therefore, the first slider 20 and the second slider 30 are moving bodies in relation to the guide shafts 25 and 35. In addition, if a structure that holds the positions of the first slider 20 and the second slider 30 constant is realized, the operation unit 40 can be held at a fixed position as in the case of the first embodiment.

  FIG. 8 shows the structure of the second embodiment in which spring members 37 and 38 that generate a frictional force between the first slider 20 and the second slider 30 are generated at the ends of the first slider 20 and the second slider 30. The spring members 37 and 38 shown in FIG. 8 have the same structure as that illustrated in FIG. In the case of adopting the structure shown in FIG. 8 in which the first slider 20 and the second slider 30 are movable bodies and a predetermined friction force is generated between the first slider 20 and the second slider 30 and the housing 8 side, the operation unit 40 is the same as the first embodiment. Can be kept stable.

  Further, FIG. 9 shows a modified structure of the second embodiment. The friction generating means provided between the first slider 20 and the housing 8 may have the structure shown in FIG. This structure is similar to that shown in FIG. In addition to this, the other structure shown in FIG. 7 can be similarly adopted as the friction generating means for generating a frictional force between the first slider 20 and the housing 8. The same applies to the friction generating means provided between the second slider 30 and the housing 8.

  In the description of the first embodiment described above, only the spring members 47 and 48 that apply the friction force to the operation unit 40 have been described. However, in FIGS. 4 to 6, structural examples including spring members 37 and 38 that generate frictional force on the first slider 20 and the second slider 30 are illustrated. That is, FIGS. 4 to 6 illustrate an input device having the structure described in the second embodiment. In this manner, the structure may include both spring members 47 and 48 that apply frictional force to the operation unit 40 and spring members 37 and 38 that apply frictional force to the first slider 20 and the second slider 30. If the frictional force is generated in the double structure, the operation unit 40 can be reliably held at a fixed position. Of course, it is good also as a structure which has arrange | positioned the spring member in either one.

  Further, another structure for stably holding the operation unit 40 in the input device M will be described. FIG. 10 is a diagram illustrating the first slider 20 and the guide shaft 25 having the structure according to the third embodiment. (A) is a top view, (B) is the figure which showed the surrounding part of the guide shaft 25 seen to the arrow P direction in (A). Three locking claws 26, 27, and 28 protrude from the end of the first slider 20. The three locking claws are arranged along the guide shaft 25 and are locked so as to sandwich the guide shaft 25 from both sides. The locking claw portions 26 and 28 at both ends are located on the same side, and the middle locking claw portion 27 is located on the opposite side. That is, the locking claws 26, 27, and 28 are alternately arranged with the guide shaft 25 therebetween. The first slider 20 is held on the guide shaft 25 via three locking claws 26, 27, 28.

  In the structure shown in FIG. 10, the locking claws 26, 27, 28 serve as friction generating means and generate a predetermined frictional force with the guide shaft 25. Therefore, the structure which can hold | maintain the operation part 40 stably in a fixed position similarly to the case of Example 2 is implement | achieved. In particular, the structure of the first slider 20 shown in FIG. 10 is easy to manufacture with a mold, and is easily assembled by pushing the locking claws 26, 27, 28 of the first slider 20 into the guide shaft 25. Yes. Therefore, the structure shown in FIG. 10 can reduce the cost because it can reduce the component cost and increase the production efficiency. The second slider 30 and the guide shaft 35 can be formed similarly.

  FIG. 11 is a diagram illustrating a modification of the third embodiment. It is the figure shown about the 1st slider 20 and the rail 12 in the structure which concerns on this modification. (A) is a top view, (B) is the figure which showed the surrounding part of the rail 12 seen to the arrow Q direction by (A). In the structure shown in FIG. 11, the three locking claws 26, 27, and 28 of the first slider 20 are locked to the guide rail 12 (see FIGS. 4 and 5) provided on the housing 8 side. It has been changed to. In the case of this structure, the cross-sectional shape of the locking claw portion can be a rectangular shape. Even with such a structure, the same effect as in the third embodiment can be obtained. In the third embodiment and this modified example, it is preferable that the locking claw portions 26, 27, and 28 are provided alternately as described above, but the locking claw portions are arranged opposite to each other at the same position to guide from both sides. A structure in which the shaft 25 and the rail 12 are sandwiched may be employed. In this case, the number of the locking claws is an even multiple.

  Further, another structure for holding the operation unit 40 at a fixed position in the input device M will be described. FIG. 12 is a diagram illustrating the operation unit 40, the first slider 20, and the second slider 30 according to the fourth embodiment. Four arm portions 55 to 58 projecting in four directions from the operation portion 40 are provided. The first arm portions 55 and 56 protruding toward both sides in the X-axis direction are in contact with the upper surface of the second slider 30. Further, the second arm portions 57 and 58 projecting toward both sides in the Y-axis direction are in contact with the lower surface of the first slider 20. In this structure, the arm portions 55 to 58 of the operation unit 40 function as friction generating means, and generate a predetermined friction force between the first slider 20 and the second slider 30. Therefore, the operation unit 40 can be stably maintained when the operation is not performed as in the other embodiments described above. Further, this structure positions the operation unit 40 in the Z-axis direction perpendicular to the X-axis and the Y-axis. Therefore, this structure realizes a structure that can stably hold the position of the operation unit 40 in the Z-axis direction. Further, as shown in the figure, the arm portions 55 and 56 are also brought into contact with the inner wall of the elongated hole 31 of the second slider 30, so that the operation portion 40 can be restrained from playing in the XY plane. Can be positioned.

  FIG. 13 is a diagram illustrating the first slider 20 and the position detection unit D-1. The magnet 1-1 included in the operation unit is disposed outside the electromagnetic conversion element 3-1. When the guide shaft 25 is formed of a magnetic material such as metal, it is preferable to employ a structure in which the magnet 1-1 is disposed so as to be far from the guide shaft 25 in this way. In FIG. 13, a predetermined frictional force is generated between the first slider 20 and the guide shaft 25 by adopting a structure similar to that shown in FIG.

  The guide shaft 25 for guiding the first slider 20 may be a general rod-shaped member, but a shaft having a cross-sectional shape illustrated in FIGS. 14A to 14E may be employed. The same applies to the guide shaft 35 that guides the second slider 30.

  FIG. 15 is a block diagram showing an example of the electrical configuration of the input device M of the above-described embodiment. The electrical configuration shown in FIG. 15 can be disposed on the substrate 10 shown in FIG. 4, for example. The electromagnetic conversion element 3-1, which detects the position in the X-axis direction, converts the magnetic field strength into a voltage and outputs it. The amplifier 151 amplifies the voltage value. The A / D converter 152 converts the signal amplified by the amplifier 151 from an analog signal to a digital signal. Similarly, the electromagnetic transducer 3-2 that detects the position in the Y-axis direction converts the magnetic field strength into a voltage and outputs it. The amplifier 153 amplifies the voltage value and supplies the amplified voltage value to the A / D converter 154. The A / D converter 154 converts the analog signal into a digital signal.

  The microprocessor unit 155 is configured around a CPU. The microprocessor unit 155 calculates X and Y axis coordinate values based on digital signals from the A / D converter 152 on the X axis side and the A / D converter 154 on the Y axis side. Then, the microprocessor unit 155 outputs the calculation data to an external device (for example, a computer) via the output unit 156.
