So, in the multi-directional inputting device 1 involved by present embodiment, by being arranged at the flexure strip 625 in the hole portion 624 of sliding part bearing piece 62, the movement along its axis direction is allowed for the first linkage part 4, and sliding part bearing piece 62 elasticity is held in the connecting piece 422 arranged in an end of the first linkage part 4, can make not engage with each other with there is not play between the first linkage part 4 and the sliding part bearing piece 62 of the first variable resistance 6, therefore when making to rotate to drive push switch 8 with the first linkage part 4 of functional unit 3 interlock, also the output accuracy of the first variable resistance 6 operated by the first linkage part 4 can be improved.

Especially, in the multi-directional inputting device 1 involved by present embodiment, in the connecting piece 422 of an end being arranged at the first linkage part 4, be provided with the planar portions 422a of the projected direction of the protuberance 32 along functional unit 3, on the other hand, in the hole portion 624 in axle portion 622 being formed at sliding part bearing piece 62, be provided with the supporting face 624a opposed with this planar portions 422a.So, moving direction when carrying out pressing operation for functional unit 3, the bearing of trend of the part of the first linkage part 4 engaged with relative to sliding part bearing piece 62 are consistent with each other, therefore, it is possible to sliding part bearing piece 62 rotates when suppressing the driving of push switch 8, the output signal from the first variable resistance 6 can be made not easily to change.

The second linkage part 5 inserted by functional unit 3 as shown in Figure 7, supported by supporting slice 215 rotationally by the one end being formed with protrusion tab 523, and the other end being formed with connecting piece 522 is supported by supporting slice 216 rotationally.Connecting piece 522 inserts the hole portion 724 being formed at the axle portion 722 of 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 is arranged opposite with insulated substrate 73.Sliding part 71 is fixed on sliding part bearing piece 72, is in and its part is 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 the state of the right side face 222 being connected to upper side body 22 by teat 723.

In addition, the second linkage part 5 is identical with the connecting state of the first linkage part 4 and the first variable resistance 6 with the connecting state of the second adjustable resistance device 7.That is, the connecting piece 522 inserting the hole portion 724 in axle portion 722, with the state by the facial 724a supporting plane portion 522a of supporting, meets abutting part 522b by flexure strip 725 bullet.That is, in axle portion 722, connecting piece 522 is in the state clamped by the facial 724a of supporting and flexure strip 725.So, by being connected to the facial 724a side of supporting by flexure strip 725 bullet, connecting piece 522 is linked to sliding part bearing piece 72 with nonseptate state.Therefore, the second linkage part 5 attended operation parts 3 tilting action and when rotating, reliably this rotational action can be passed to the second adjustable resistance device 7.

Below, the action that Fig. 9 ~ Figure 11 illustrates the multi-directional inputting device 1 involved by present embodiment is contrasted.Fig. 9 ~ Figure 11 is respectively the key diagram of the action of the multi-directional inputting device 1 involved by present embodiment.In fig .9, the operate condition of the multi-directional inputting device 1 when carrying out pressing operation for functional unit 3 is shown.In Figure 10 and Figure 11, show at the operate condition carrying out the multi-directional inputting device 1 when fascinating operation for functional unit 3.In Fig. 10, operate condition when fascinating operation is carried out in the side, right shown to multi-directional inputting device 1, and in fig. 11, the rear side shown to multi-directional inputting device 1 carries out operate condition when fascinating operation.In addition, for convenience of explanation, in Fig. 9 ~ Figure 11, side body 22 is eliminated.For convenience of explanation, in Fig. 10, the second adjustable resistance device 7 is omitted.

As shown in Figure 9, as carried out pressing operation for functional unit 3, then the first linkage part 4 linked by axle portion 33 moves to the lower side in case 2.That is, the first linkage part 214 moves according to the mode being fulcrum with the abutting part of the end and supporting slice 214 that are formed with connecting piece 422.Thereupon, pressing tablet 421 also moves to the lower side, then the switch portion 82 of the push switch 8 of the pressing tablet 421 of pressing mounting to the lower side.Accordingly, such as, from the switching circuit be contained in push switch 8 via portion of terminal 83, the Continuity signal of push switch 9 is externally exported.

When like this carry out pressing operation for functional unit 3, 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, also can not be depressed in case 2 because of functional unit 3, the first linkage part 4 just rotates centered by its axis direction.Therefore, the sliding part 61 being linked to the first variable resistance 6 of the first linkage part 4 is in and also can not rotates and maintain the state of initial position.

In addition, if to carry out tilting towards the side, right of multi-directional inputting device 1 (fascinating) operation for functional unit 3, then as shown in Figure 10, the first linkage part 4 linked by axle portion 33 rotates in case 2.In this situation, the first linkage part 4 pressing tablet 421 to be placed in the state of the switch 82 of push switch 8, and a part of the recess 214a of the supporting slice 214 of following side body 21 be rotating fulcrum rotate.With the rotational action of this first linkage part 4, connecting piece 422 rotates, then the sliding part bearing piece 62 being linked to connecting piece 422 and the sliding part 61 being fixed on sliding part bearing piece 62 rotate.With the spinning movement of this sliding part 61 correspondingly, elastic connection part 612 and sliding sheet 613 slide respectively on swept resistance volume graphic 631 and collector body figure 632.Accordingly, the signal corresponding to sliding position of elastic connection part 612 and sliding sheet 613 is externally exported by terminal 634.

When like this for functional unit 3 carry out fascinating operation, protuberance 32 is sliding movement elongated hole 51 in, and therefore 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 the initial position of functional unit 3 only in case 2 tilts, therefore the first linkage part 4 can not also be depressed.Therefore, be in also can not depress switch portion 82 and maintain the state of initial position for push switch 8.

And then if carry out towards the rear side of multi-directional inputting device 1 operation of fascinating for functional unit 3, then as shown in figure 11, in elongated hole 51, protuberance 32 abuts, and the second linkage part 5 rotates in case 2.In this situation, a part of recess 215a, 216a of the supporting slice 215,216 of the second linkage part less than 5 side body 21 be rotating fulcrum rotate.With the rotational action of this second linkage part 5, connecting piece 522 rotates, then the sliding part bearing piece 72 being linked to connecting piece 522 and the sliding part 71 being fixed on sliding part bearing piece 72 rotate.With the spinning movement of this sliding part 71 correspondingly, elastic connection part 712 and sliding sheet 713 slide respectively on swept resistance volume graphic 731 and collector body figure 732.Accordingly, the signal corresponding to sliding position of elastic connection part 712 and sliding sheet 713 is externally exported by terminal 734.

When like this for functional unit 3 carry out fascinating operation, functional unit 3 can not affect the state of the first linkage part 4.More specifically, the axle portion 33 of functional unit 3 only rotates 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 is in by lower side body 21(more specifically, is supporting slice 214) supporting and maintain the state of initial position.In addition, because the initial position of functional unit 3 only in case 2 tilts, therefore the first linkage part 4 can not also be depressed.Therefore, be in can not depress switch portion 82 and maintain the state of initial position for push switch 8.

When free position in the state shown in Fig. 9 ~ Figure 11, if remove the operation (pressing operation, operation of fascinating) for functional unit 3, then 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, when removing the pressing operation for functional unit 3, by the active force of helical spring 91, functional unit 3 is pushed back upward, return to initial position.On the other hand, under the state shown in Figure 10 and Figure 11, the part of the spherical shape portion 921b that the disc-shape portion 921 being in driving body 92 is arranged rides over the state on the inclination face 211b of lower side body 21.From the state shown in Figure 10 and Figure 11, remove for functional unit 3 fascinate operation when, the active force of helical spring 91 acts on the part of the spherical shape portion 921b riding on facial 211b, and spherical shape portion 921b is slided along the direction slided from the facial 211b that tilts.Accordingly, functional unit 3 tilts to the opposition side in tilting action direction, returns to initial position.
