The circuit board 4 is placed on the middle stage 1b and fixed with a plurality of screws 5.
In this case, the circuit board 4 has a cross shape (see FIG. 4), and a convex portion 6 is formed on the middle stage 1b of the base 1 to position the cross-shaped circuit board 4 before fixing. ing.

  Necessary wiring patterns (not shown) are provided in advance on the surface of the circuit board 4 on the side opposite to the base 1 (upper surface in the drawing) or on the surface on the base 1 side (lower surface in the drawing). The magnetic sensor 7 is mounted and fixed at the center of the side surface, and the magnetic sensor 7 is fixed to the base 1 via the circuit board 4. In this case, the magnetic sensor 7 is a three-axis magnetic sensor effective in the three-axis directions of vertical (X), horizontal (Y), and height (Z).

  A first holder 8 is placed on the upper stage 1 c of the base 1 and is fixed by a plurality of screws 9. The first holder 8 has a disk shape and has a recess 10 on the surface of the central portion on the base 1 side (see FIG. 1). A magnetic body 11 is fitted into the recess 10 and fixed. Yes.

  In this case, the magnetic body 11 has a cross shape as shown in an enlarged view in FIG. 5, that is, the density of the central portion 11a (particularly, the density of the constituent material per unit area) is increased, and the central portion 11a. Further, it is extended in a cross shape in the vertical and horizontal directions (extension portions 11b to 11e), and its constituent material is metal, and is fitted into the recess 10 of the first holder 8 and fixed as described above. The magnetic body 11 is fixed to the base 1 via the first holder 8 by fixing the first holder 8 to the base 1 as described above.

Around the central portion of the first holder 8, a plurality of (in this case, four) circular holes 12 are formed. In addition, around the central portion of the surface of the first holder 8 on the base 1 side. Forms a plurality of (in this case, four) protrusions 13.
A second holder 14 is disposed on the base 1 side of the first holder 8. The second holder 14 has a disk shape smaller in diameter than the first holder 8, has a hole 15 in the center, and has a recess 16 on the surface on the side of the base 1 connected to the hole 15. The magnet 17 is fitted into the recess 16 and fixed.

  As shown in FIG. 1 (a), the magnet 17 has a disk shape that is sufficiently smaller in diameter than the extension dimension of the magnetic body 11, and as shown in FIG. 6, the base 1 side and the non-base 1 side. N pole and S pole are separately magnetized, and as shown in FIG. 3, it corresponds to the magnetic sensor 7 on the base 1 side and corresponds to the magnetic body 11 on the counter base 1 side. ing. As a result, the magnet 17 magnetically attracts the magnetic body 11, and the first holder 8 is brought into contact with the protrusion 13 of the first holder 8.

Further, a plurality of (in this case, four) pillars 18 project from the periphery of the surface of the second holder 14 on the side opposite to the base 1, and the magnetic attraction force of the magnet 17 with respect to the magnetic body 11. Thus, the column 18 is projected through the hole 12 of the first holder 8 to the side opposite to the base 1. It should be noted that the hole 12 of the first holder 8 is sufficiently large with respect to the support 18 and has a gap G ₁ between them (around the support 18).

The operation element 2 is disposed on the side opposite to the base 1 of the second holder 14 and the first holder 8. The operation element 2 has a closed short cylindrical shape symmetrical to the base 1 and has a diameter larger than that of the base 1, and the support column of the second holder 14 is covered with the base 1 by a plurality of screws 19. 18 is attached. As a result, the magnet 17 is held by the operator 2 via the second holder 14. Further, in the mounted state, the operation element 2 is separated from the outer periphery of the base 1 and the side opposite to the base 1, that is, between the operation element 2 and the base 1, A gap G ₂ is provided on the outer periphery, and a gap G ₃ is provided on the side opposite to the base 1. The operating element 2 has several holes 21 and 22 in addition to the mounting hole 20 through which the screw 19 is passed. The surface of the operating element 2 on the side opposite to the base 1 is covered with the cover so as to cover them. The board 3 is installed.

Next, the operation of the input device having the above configuration will be described.
In the above configuration, the operating element 2 is located between the gap G ₁ between the hole 12 of the first holder 8 and the column 18 of the second holder 14 and the operating element 2 outside the periphery of the base 1. min gap G ₂ is movable operation in a direction parallel to the base 1, the minute gap G ₃ between the operating element 2 of the anti-base 1 side of the base 1, intersects the base (especially Can be moved in the direction perpendicular to the direction. That is, the operation element 2 can be moved in the three axis directions.

When the operating element 2 move (slide) operating in a direction parallel to the base 1, by the second holder 14 is both moving and operating element 2 within the dimension of the gap G ₁ and gap G _2, As representatively shown in FIGS. 1A to 1D, the magnet 17 is displaced in parallel from the magnetic body 11.
In this case, FIGS. 1A to 1D representatively show a situation where the operation element 2 (magnet 17) is moved to the left in the figure, and the magnet 17 magnetically attracts the extension 11e of the magnetic body 11. Thus, the magnet 17 basically proceeds along the extension 11e of the magnetic body 11, and the movement of the operation element 2 is guided.

Further, as shown in FIG. 4A, the magnet 17 corresponds to the central portion 11a having a high density of the magnetic body 11 and has attracted the magnetic body 11 with the strongest magnetic force 4 before movement. As shown in (b), in a situation where the operating element 2 is moved slightly to the left in the drawing (up to the middle part of the extension part 11e), the magnet 17 is separated from the center part 11a where the density of the magnetic body 11 is large. As a result, the magnetic attraction force of the magnet 17 with respect to the magnetic body 11 is weakened, and when the user feels the weakening, a feeling for the moving operation of the operating element 2 at this time is given.
At this time, the magnet 17 is also displaced from the magnetic sensor 7 in the same direction, and the magnetic flux passing from the magnet 17 through the magnetic sensor 7 is changed, whereby the moving operation of the operating element 2 at this time is detected.

  If the operating force applied to the operating element 2 is released from this state, the magnet 17 returns to the original position by the magnetic force exerted on the central portion 11a having a high density of the magnetic body 11, and the operating element 2 is also moved to the original position accordingly. Returned to

Next, as shown in FIG. 4C, in a situation where the operation element 2 is moved further to the left in the drawing (to the tip of the extension portion 11e), the magnet 17 is separated from the extension portion 11e of the magnetic body 11. By starting, the magnetic attraction force of the magnet 17 with respect to the magnetic body 11 is further weakened, and when the user feels the further weakening, a feel for the moving operation of the operation element 2 at this time is given.
At this time, the magnet 17 is further displaced in the same direction from the magnetic sensor 7 and the magnetic flux passing from the magnet 17 through the magnetic sensor 7 is further changed, so that the moving operation of the operating element 2 at this time is detected.

  If the operating force applied to the operating element 2 is released from this state, the magnet 17 returns to the previous position by the magnetic force exerted on the extension 11e of the magnetic body 11, and further exerts on the central portion 11a of the magnetic body 11. Since the magnetic head returns to the original position, the operation element 2 is also returned to the original position accordingly.

Next, as shown in FIG. 4D, in a situation where the operation element 2 is moved and operated slightly upward (until away from the tip of the extension portion 11e) in the drawing, the magnetic attraction force of the magnet 17 with respect to the magnetic body 11 is further increased. When the user feels weaker and further weakened, a feel for the moving operation of the operation element 2 at this time is given.
At this time, the magnet 17 is further displaced in the same direction from the magnetic sensor 7 and the magnetic flux passing from the magnet 17 through the magnetic sensor 7 is further changed, so that the moving operation of the operating element 2 at this time is detected.

  If the operating force applied to the operating element 2 is released from this state, the magnet 17 returns to the previous position by the magnetic force exerted on the extension 11e of the magnetic body 11, and further exerts on the central portion 11a of the magnetic body 11. Since the magnetic head returns to the original position, the operation element 2 is also returned to the original position accordingly.

On the other hand, when the operating element 2 is moved (pushed) operated in a direction intersecting the base 1, by the second holder 14 is both moving and operating element 2 within the dimension of the gap G _3, Fig. 7 As shown, the magnet 17 moves away from the magnetic body 11 and approaches the magnetic sensor 7. Thereby, the magnetic attraction force of the magnet 17 reaching the magnetic body 11 is weakened, and when the user feels the weakening, a feeling for the moving operation in the direction intersecting the base 1 of the operation element 2 is given.
At this time, since the magnet 17 has approached the magnetic sensor 72, the magnetic flux passing from the magnet 17 through the magnetic sensor 7 changes, whereby a moving operation in the direction intersecting the base 1 of the operating element 2 is detected.

  After that, when the operating force applied to the operation element 2 is released, the magnet 17 returns to the original position close to the magnetic body 11 by the magnetic attraction force of the magnet 17 with respect to the magnetic body 11, and from the second holder 14. Accompanying the operation element 2, the operation element 2 is returned to the original position before the operation (state in FIG. 1).

  As described above, according to the input device configured as described above, when the operating element 2 is moved in a direction parallel to the base 1, the magnet 17 moves along the extension portions 11 b to 11 e of the magnetic body 11 to move the operating element 2. Is guided, it becomes easy to operate the operation element 2 in a specific direction. In addition, the feel of the operating element 2 is given by a change in the magnetic attractive force with respect to the magnetic body 11 due to the movement of the magnet 17, and the operating element 2 is generated by the magnetic attractive force exerted on the central portion of the magnetic body 11 by the moved magnet 17. Since the position can be returned to the position, the magnet 17 and the magnetic body 11 are commonly used to guide the movement of the operation element 2, to give a feeling of movement of the operation element 2, and to return the moved operation element 2 to the original position. It can be used with a small number of parts, and the structure can be kept simple.
