As shown in Figure 8, the link sheet 422 of the hole section 624 of insertion axial region 622 is the state by the facial 624a supporting of supporting with planar portions 422a, and abutting part 422b is connect by flexure strip 625 bullets.That is,, in axial region 622, link sheet 422 in the state by the facial 624a of supporting and flexure strip 625 clampings.So, by flexure strip 625 bullets, be connected to the facial 624a side of supporting, link thus sheet 422 and be linked to sliding part bearing piece 62 with nonseptate state.Therefore, the tilting action of the first linkage part 4 attended operation parts 3 and, in the situation of rotating, can reliably this rotation action be passed to the first variable resistance 6.

So, in present embodiment in related multi-directional inputting device 1, by the flexure strip 625 in the hole section 624 that is arranged at sliding part bearing piece 62, allow the movement along its axis direction for the first linkage part 4, and sliding part bearing piece 62 elasticity are held in the link sheet 422 arranged in an end of the first linkage part 4, can make not engage with each other between the sliding part bearing piece 62 of the first linkage part 4 and the first variable resistance 6 with not having play, therefore in the situation that make to drive push switch 8 with the first linkage part 4 rotations of functional unit 3 interlocks, also can improve the output accuracy of first variable resistance 6 that can operate by the first linkage part 4.

Especially, in present embodiment in related multi-directional inputting device 1, on the link sheet 422 of an end that is arranged at the first linkage part 4, be provided with along the planar portions 422a of the projected direction of the protuberance 32 of functional unit 3, on the other hand, in the hole section 624 of the axial region 622 that is formed at sliding part bearing piece 62, be provided with and the facial 624a of the opposed supporting of this planar portions 422a.So, carry out moving direction in the situation of pressing operation, consistent with each other with the bearing of trend of the part of the first linkage part 4 engaged with respect to sliding part bearing piece 62 for functional unit 3, therefore in the time of can suppressing the driving of push switch 8,62 rotations of sliding part bearing piece, can make to be difficult for change from the output signal of the first variable resistance 6.

Insert the second logical linkage part 5 as shown in Figure 7 by functional unit 3, be formed with an end of protrusion tab 523 rotationally by supporting slice 215 supportings, be formed with the other end that links sheet 522 and supported by supporting slice 216 rotationally.Link the hole section 724 that sheet 522 inserts the axial region 722 that is formed at the sliding part bearing piece 72 that the second adjustable resistance device 7 has.In the second adjustable resistance device 7, sliding part bearing piece 72 and insulated substrate 73 arranged opposite.Sliding part 71 is fixed in sliding part bearing piece 72, in its part being slidably connected to the resistive element figure 731 of insulated substrate 73, the state of collector body figure 732.In addition, sliding part bearing piece 72 is in being connected to the state of the right side face 222 of upper side body 22 by teat 723.

In addition, the connecting state of the connecting state of the second linkage part 5 and the second adjustable resistance device 7 and the first linkage part 4 and the first variable resistance 6 is identical.That is, the link sheet 522 of the hole section 724 of insertion axial region 722, with the state by the facial 724a supporting plane 522a of section of supporting, meets abutting part 522b by flexure strip 725 bullets.That is,, in axial region 722, link sheet 522 in the state by the facial 724a of supporting and flexure strip 725 clampings.So, by be connected to the facial 724a side of supporting by flexure strip 725 bullets, link sheet 522 and be linked to sliding part bearing piece 72 with nonseptate state.Therefore, the tilting action of the second linkage part 5 attended operation parts 3 and, in the situation of rotating, can reliably this rotation action be passed to the second adjustable resistance device 7.

Below, contrast Fig. 9～Figure 11 illustrates the action of the related multi-directional inputting device of present embodiment 1.Fig. 9～Figure 11 is respectively the key diagram of the action of the related multi-directional inputting device of present embodiment 1.In Fig. 9, show in the situation that carry out the operate condition of the multi-directional inputting device 1 of pressing operation for functional unit 3.In Figure 10 and Figure 11, show in the situation that for the fascinated operate condition of multi-directional inputting device 1 of operation of functional unit 3.In Figure 10, show to the right-hand side of multi-directional inputting device 1 fascinated the operation situation under operate condition, in Figure 11, show to the rear side of multi-directional inputting device 1 fascinated the operation situation under operate condition.In addition, for convenience of explanation, in Fig. 9～Figure 11, omitted upper side body 22.For convenience of explanation, in Figure 10, also omitted the second adjustable resistance device 7.

As shown in Figure 9, as for functional unit 3, carried out pressing operation, the first linkage part 4 linked by axial region 33 moves to the lower side in case 2.That is, the first linkage part 214 moves according to take the mode that the abutting part that is formed with the end that links sheet 422 and supporting slice 214 is the fulcrum rotation.Thereupon, pressing tablet 421 also moves to the lower side, presses to the lower side the switch portion 82 of the push switch 8 of mounting pressing tablet 421.Accordingly, for example, from being contained in the interior switching circuit of push switch 8 via portion of terminal 83, to the Continuity signal of outside output push switch 9.

In the situation that so for functional unit 3, carry out pressing operation, functional unit 3 can not affect the state of the second linkage part 5.Therefore, the second linkage part 5 is in by lower side body 21(more specifically, supporting slice 215,216) supporting and maintain the state of initial position.In addition, can be because functional unit 3 is depressed in case 2 yet, the first linkage part 4 just rotates centered by its axis direction.Therefore, the sliding part 61 that is linked to the first variable resistance 6 of the first linkage part 4 maintains the state of initial position in also not rotating.

In addition, if for functional unit 3 towards (fascinating) operation of being tilted of the right-hand side of multi-directional inputting device 1, as shown in figure 10, the first linkage part 4 linked by axial region 33 is in the interior rotation of case 2.In this situation, the first linkage part 4 is so that pressing tablet 421 is loaded in the state of the switch 82 of push switch 8, and the part of the recess 214a of the supporting slice 214 of following side body 21 is that rotating fulcrum ground rotates.Follow the rotation action of this first linkage part 4, link sheet 422 rotations, sliding part 61 rotations that are linked to the sliding part bearing piece 62 that links sheet 422 and are fixed in sliding part bearing piece 62.With the spinning movement of this sliding part 61 correspondingly, elastic connection part 612 and slip sheet 613 and slide on swept resistance volume graphic 631 and collector body figure 632 respectively.Accordingly, elastic connection part 612 and the corresponding signal in position that slips that slips sheet 613 are exported to outside by terminal 634.

In the situation that, so for functional unit 3 operation of being fascinated, protuberance 32 slips movement in slotted hole 51, so functional unit 3 does not affect the state of the second linkage part 5.Therefore, the second linkage part 5 is in by lower side body 21(more specifically, supporting slice 215,216) supporting and maintain the state of initial position.In addition, because 3 initial positions in case 2 of functional unit tilt, therefore can not depress the first linkage part 4 yet.Therefore, push switch 8 is not in can depress switch section 82 and maintain the state of initial position yet.

And then, if for functional unit 3 towards the operation of being fascinated of the rear side of multi-directional inputting device 1, as shown in figure 11, in slotted hole 51, protuberance 32 butts, the second linkage part 5 is in the interior rotation of case 2.In this situation, the part of recess 215a, the 216a of the supporting slice 215,216 of the following side body 21 of the second linkage part 5 is that rotating fulcrum ground rotates.Follow the rotation action of this second linkage part 5, link sheet 522 rotations, sliding part 71 rotations that are linked to the sliding part bearing piece 72 that links sheet 522 and are fixed in sliding part bearing piece 72.With the spinning movement of this sliding part 71 correspondingly, elastic connection part 712 and slip sheet 713 and slide on swept resistance volume graphic 731 and collector body figure 732 respectively.Accordingly, elastic connection part 712 and the corresponding signal in position that slips that slips sheet 713 are exported to outside by terminal 734.

In the situation that, so for functional unit 3 operation of being fascinated, functional unit 3 can not affect the state of the first linkage part 4.More specifically, 33 of the axial regions of functional unit 3 rotate in the inserting hole 41a of the first linkage part 4, and the first linkage part 4 can not rotate.Therefore, the first linkage part 4, in by lower side body 21(more specifically, is supporting slice 214) supporting maintains the state of initial position.In addition, because 3 initial positions in case 2 of functional unit tilt, therefore can not depress the first linkage part 4 yet.Therefore, push switch 8 is in can not depress switch section 82 and maintain the state of initial position.

In the situation that the free position in the state shown in Fig. 9～Figure 11, if remove the operation (pressing operation, the operation of fascinating) for functional unit 3, functional unit 3 returns to initial position (state shown in Fig. 5) by the active force of helical spring 91.That is, from the state shown in Fig. 9, remove in the situation for the pressing operation of functional unit 3, the active force by helical spring 91 by functional unit 3 upward side pressure return, return to initial position.On the other hand, under the state shown in Figure 10 and Figure 11, a part that is in the 921b of spherical shape section that the disc-shape section 921 of driving body 92 arranges rides over the state on the inclination face 211b of lower side body 21.From the state shown in Figure 10 and Figure 11, in the situation of releasing for the operation of fascinating of functional unit 3, the active force of helical spring 91 acts on a part that rides over the 921b of spherical shape section on facial 211b, and the 921b of spherical shape section is slided along the direction slided from the facial 211b that tilts.Accordingly, functional unit 3 tilts to the opposition side of tilting action direction, returns to initial position.
