Here, the distortion detecting elements 20a, 20b, 2
Since the resistance values of 0c and 20d are all the same in the initial state, the voltage of the terminal T1 and the voltage of the terminal T2 are
In each case, the voltage at the terminal T3 and the median value of the voltage V are exactly the same. Then, for example, when the resistance value of the strain detection element 20a decreases and the resistance value of the strain detection element 20b increases, the voltage at the terminal T1 increases. Thereby, the device to which the present apparatus is connected can move the cursor in the X-axis direction. Similarly, when the resistance values of the strain detection elements 20c and 20d change, the voltage at the terminal T2 increases,

Although the above embodiment has been described using four strain detecting elements 20a, 20b, 20c, and 20d, two strain detecting elements 20a and 20c may be used. As shown in FIG. 17, a film-shaped insulating plate 25 made of an insulating material is provided with a band-like portion 26 and a projecting portion 27 protruding from a side end of the band-like portion 26.
And a hole 28 formed over the overhang portion 27 and the band portion 26. And this insulating plate 25
As shown in FIGS. 2 and 3, the operation unit 3 of the operation member 2 is inserted through the hole 28, is placed on the flexible substrate 13, and is attached to the coating units 22 and 23 with an adhesive. In addition,
The insulating plate 25 is not simply attached by an adhesive, but simply
What is mounted on the flexible substrate 13 may be used. When the insulating plate 25 is mounted on the flexible substrate 13, the insulating plate 25 allows the strain detecting elements 20 a, 2
0b, 20c, 20d, the resistor 21, and a part of the conductive pattern 18 are covered together with the covering parts 22, 23, and as shown in FIG. 2, a part of the band-like part 26 is an end of the base 5c.

As shown in FIGS. 1 to 3, the shield plate 29 is inserted into the hole 30 through the operation portion 3 of the operation member 2 and placed on the insulation substrate 25 or attached to the insulation substrate 25 with an adhesive. Then, except for a part of the band-like portion 26 of the insulating substrate 25, almost the entire surface is covered, and the protruding piece 33 is located in the depression 7 of the operation member 2.

The input device operates as follows. When the operation unit 3 of the operation member 2 is tilted in the X1 direction,
Since the upper surface of the beam portion 4a flexes in the extending direction and the upper surface of the beam portion 4b flexes in the contracting direction, the resistance value of the strain detecting element 20a on the beam portion 4a increases, but the strain detection on the beam portion 4b is detected. The resistance of element 20b decreases. Conversely, when the operation portion 3 of the operation member 2 is tilted in the X2 direction, the upper surface of the beam portion 4a bends in the contracting direction and the upper surface of the beam portion 4b bends in the extending direction. While the resistance of the element 20a decreases, the resistance of the strain detection element 20b on the beam 4b increases. In any case, a change occurs in the voltage of the terminal T1,
The device to which the apparatus is connected can move the cursor in the X-axis direction.

When the operating portion 3 of the operating member 2 is tilted in the Y1 direction, the upper surface of the beam portion 4c flexes in the extending direction and the upper surface of the beam portion 4d flexes in the contracting direction. While the resistance value of the strain detection element 20c increases, the resistance value of the strain detection element 20d on the beam 4d decreases. Conversely, when the operation portion 3 of the operation member 2 is tilted in the Y2 direction, the upper surface of the beam portion 4c bends in the contracting direction and the upper surface of the beam portion 4d bends in the extending direction. While the resistance of the element 20c decreases, the resistance of the strain detection element 20d on the beam 4d increases. In any case, a change occurs in the voltage of the terminal T2, and the cursor can be moved in the Y-axis direction.

When the operating portion 3 of the operating member 2 is pressed in the axial direction, the operating portion 3 moves in a small gap between the projection 9 and the mounting plate 1, so that the resistance value of the resistor 21 is slightly reduced. Change, which changes the voltage at terminal T3,
The cursor is moved in the Z-axis direction. As described above, the cursor is moved in the X, Y, and Z-axis directions by the movement of the operation unit 3, and static electricity generated when the operation unit 3 is operated is dissipated by the shield plate 29 due to the presence of the shield plate 29. The conductive pattern 18 and the strain detecting elements 20a, 20b, 20c, and 20d disposed on the operation member 2 do not break down.

In the above embodiment, the beams 4a, 4b,
