As shown in Figure 2, periphery is integrally formed in the periphery that keeps 2 four jiaos of baskets with among the maintaining part 2e of movable electrode 4 several with common electrode 5 by inlaying to be shaped, and only makes and be formed on periphery and expose from the maintenance face 2f of several maintaining parts 2e with the protuberance 5c on the common electrode 5.In addition, each periphery has with common electrode 5 and is used for the leading-out terminal 5a that draws to the outside of basket 2.As previously mentioned, for the leading section 5b of this leading-out terminal 5a and periphery are differentiated respectively with fixed contact 6 and central each leading-out terminal 3a, 6a, leading section 3b, the 6b of 8a, 8b with common electrode 8 with fixed electrode 3, central authorities, and make these each leading-out terminal 3a, 5a, 6a, 8a form different shapes.
As shown in Figure 2, central authorities are integrally formed in by inlaying to be shaped with fixed contact 6: the bottom surface of the inside of the blank part 2a of basket 2 and the inboard of guide wall 2b (hereinafter referred to as " bottom surface of guide wall inboard ") 2d.In addition, these central authorities are configured to only make that to be formed at these central authorities outstanding and expose from described bottom surface 2d with the protuberance 6c of fixed contact 6 with fixed contact 6.In addition, these central authorities have with fixed contact 6 and are used for the leading-out terminal 6a that draws to the outside of basket 2, and as previously mentioned, and its leading section 6b forms and above-mentioned each leading-out terminal 3a, 5a, leading section 3b, the 5b of 8a, shape that 8b is different.
As shown in Figure 2, central authorities, form at the bottom surface of guide wall inboard 2d and to surround but do not contact the plane U font of the periphery of central authorities' usefulness fixed contact 6 by inlaying shaping with common electrode 8.In addition, these central authorities are configured to only make the central authorities that are formed at the U font outstanding and expose from described bottom surface 2d with the protuberance 8c of common electrode 8 with common electrode 8.In addition, these central authorities have with common electrode 8 and are used for the leading-out terminal 8a that draws to the outside of basket 2, and as previously mentioned, and the leading section 8b of this leading-out terminal 8a forms and above-mentioned each leading-out terminal 3a, 5a, leading section 3b, the 5b of 6a, shape that 6b is different.
As Fig. 1, Fig. 9 and shown in Figure 10, central authorities with movable electrode 7 have upward outstanding form dome-type bend 7a and with the contacted pedestal part 7b of protuberance 8c of central authorities' usefulness common electrode 8.It is relative with fixed contact 6 with central authorities that these central authorities are configured to leave specified gap ground with movable electrode 7.In addition, the diameter of this pedestal part 7b equates with the distance between relative each protuberance 8c of common electrode 8 with central authorities.And as Fig. 9 and shown in Figure 10, these central authorities are covered central authorities with movable electrode 7 and are fixed with resin sheet 7c with the fixing of movable electrode 8 from the top.
As Fig. 1, Fig. 8, Fig. 9 and shown in Figure 10, functional unit 9 has operating body 10, central authorities pressing component 11 and periphery pressing component 12.
As Fig. 1, Fig. 9 and shown in Figure 10, operating body 10 is formed has columned protuberance 10b, described protuberance 10b form discoid operating portion 10a below fasten with pressing component 11 with central authorities.
Periphery has and the internal diameter roughly the same diameter of periphery with movable electrode 4 with pressing component 12, and forms the round flange shape.This periphery has below its periphery with pressing component 12 pushes the periphery press section 12a of periphery with movable electrode 4, and the heart partly has medium pore 12b therein.In addition, partly be formed with the protruding wall 12c of circular convex in the outer upper surface of this medium pore 12b.
Central authorities with pressing component 11 according to from top to bottom order (towards the order of pressing direction PD of functional unit 9), have and form columned insertion installation portion 11a and form circular suppressing portion 11b, wherein, described insertion installation portion 11a has the diameter of movable embedding periphery with the medium pore 12b of pressing component 12, and described suppressing portion 11b has than inserting installation portion 11a and the periphery big diameter of diameter with the medium pore 12b of pressing component 12.In addition, insert installation portion 11a and have recess 11c with the cylindric protuberance 10b tabling of operating body 10, suppressing portion 11b has at its lower surface and pushes the central authorities press section 11d of central authorities with the convex of movable electrode 7.And central authorities are configured in the basket 2 as follows with pressing component 11: will insert installation portion 11a and insert the medium pore 12b of logical periphery with pressing component 12, and make the protuberance 10b and the recess 11c tabling of central authorities with pressing component of operating body 10.
Lid 13 usefulness metallic plates and forming have and the rectangle of the equal size of periphery of basket 2.In addition, near the central authorities of this lid 13, be formed with: have the medium pore 13a of the circle of the diameter bigger, run through simultaneously being provided with inserting hole 13b respectively at this lid 13 four jiaos than the diameter of protruding wall 12c.This lid 13 is configured in the top of periphery with pressing component 12, if operating body 10 is slided to circumferencial direction arbitrarily, but then periphery with pressing component 12 in the manner as described below by art skating clamping movably: periphery slides on the upper surface 2j of the guide wall 2b of basket 2 with the lower surface of pressing component 12, and its upper surface slide is in the bottom 13c of the medium pore 13a of lid 13 simultaneously.In addition, if periphery slides significantly with pressing component 12, then the peripheral part of its protruding wall 12c contacts with the inner peripheral surface of the medium pore 13c of lid 13, thereby plays a role as limiting section.
Reset components 14 is made of elastomeric elements such as rubber or elastomeric materials, is configured in the top of lid 13 as shown in Figure 9.This reset components 14 is formed the identical profile of profile size that has with lid 13, and the 14a of elastic diaphragm portion with ring-type, the 14a of this elastic diaphragm portion has snakelike cross section, and described snakelike cross section produces the recuperability of the configuration initial position (center) that resets to this operating body 10 with respect to the slide direction of operating body 10.Central part at the 14a of this elastic diaphragm portion is formed with size for covering the medium pore 14b of central authorities with the periphery of the recess 11c of pressing component 11, and be formed with four protuberance 14c at the lower surface of the 14a of this elastic diaphragm portion, these four protuberance 14c insert the inserting hole 13b of logical lid 13, simultaneously the maintained portion 4a of periphery with movable electrode 4 are pushed and remain on the maintenance face 2f and periphery usefulness common electrode 5 of maintaining part 2e.In addition, this reset components 14 forms airtight and covers the lid shape that is formed on the peristome on the basket 2, and except medium pore 14b, does not have formation to make moisture and dust etc. invade the hole of the inside of basket 2 from the outside.
Limiting part 15 forms the annular plate-like of the outer upper surface of the 14a of elastic diaphragm portion that covers reset components 14, outstanding downwards with four wrist 15a that the claw 2i of each the limit lateral surface that is formed on basket 2 fastens, and form medium pore 15b for tubular with interior perimembranous is upright for the action that does not hinder the 14a of elastic diaphragm portion.This limiting part 15 is engaged to each claw 2i from the top of lid 13 and reset components 14 with each wrist 15a and assembles, thereby has limited lid 13 and reset components 14.
The following describes the effect of the multi-way input device 1 of first execution mode.
As Figure 11 or shown in Figure 12, if being moved to radial outside slip arbitrarily, the operating body 10 of the functional unit 9 of multi-way input device 1 carries out input operation, then periphery is with the bottom 13c slide relative of the medium pore 13a of the upper surface 2j of pressing component 12 and the guide wall 2b of basket 2 and lid 13, move to this direction by slide simultaneously, periphery contacts with movable electrode 4 with periphery with press section 12a with the periphery of pressing component 12.Move this operating body 10 if further slide, then periphery makes periphery with movable electrode 4 distortion with press section 12a, thereby periphery uses movable electrode 4 to contact and conducting with fixed contact 3 with in the bottom periphery.Thus, multi-way input device 1 can detect the input operation to any radial outside to operating body 10.
This input operation to radial outside is out of shape on thickness direction with movable electrode 4 by making periphery, can produce big repulsive force with movable electrode 4 at periphery thus.Here, because the periphery of the multi-way input device 1 of first execution mode has reaction force adjustment part 4c, 4d with movable electrode 4, therefore, periphery all is constant with the reaction force on the circumferencial direction of movable electrode 4 at any position, thereby can reduce operating physical force inhomogeneous of radial outside.This reaction force adjustment part 4c, 4d are owing to be formed: the width dimensions of the 4e of maintained portion 4a near is littler than the width dimensions of the part 4f in addition of maintained portion 4a near, therefore, near 4e maintained portion 4a, reaction force may reduce, and near the part 4f beyond maintained portion 4a, reaction force may strengthen.Thus, owing to can reduce inhomogeneous to the operating physical force of radial outside, therefore, the operation sense of touch of multi-way input device 1 improves.
As previously mentioned, reaction force adjustment part 4c, 4d can be formed: as shown in Figure 4 and Figure 5, the thickness of the 4e of maintained portion 4a near is than the thin thickness of the part 4f beyond the maintained portion 4a near, perhaps as shown in Figure 6 and Figure 7, by periphery with the maintained portion 4a of movable electrode 4 near beyond part 4f, form concavity or convex along its periphery, thereby with the situation that described width dimensions is changed in the same manner, can near maintained portion 4a, reduce this reaction force by 4e, and near the part 4f beyond maintained portion 4a strengthens this reaction force.
In addition, because this periphery has by the support 2g of basket 2 with movable electrode 4 and does not have any 4b of the portion that is supported that is restrictedly supporting, therefore, result from be supported the 4b of portion near the state that increases hardly of reaction force under can stably support periphery with movable electrode 4.In addition,, the formation operation of reaction force adjustment part 4d can be saved, thereby the manufacturing cost of periphery can be reduced with movable electrode 4 by making this be supported the 4b of portion and reaction force adjustment part 4d is integrally formed.
In addition as shown in Figure 2, support this periphery is formed on basket 2 with the maintaining part 2e of the basket 2 of the maintained portion 4a of movable electrode 4 four bights.Thus, can not strengthen the profile of basket 2, and can suitably utilize the bight of the basket 2 that becomes the dead angle (dead space) in the basket 2 easily, thereby can try hard to realize the miniaturization of multi-way input device 1.In addition, owing to be formed with and the periphery common electrode 5 of periphery with movable electrode 4 conductings at the maintenance face 2f of this maintaining part 2e, therefore, the space and the maintaining part 2e that can integrally formedly only be used to periphery is contacted with movable electrode 4 with periphery with common electrode 5 and be provided with, thus can further realize the miniaturization of multi-way input device 1.
In addition, the multi-way input device 1 of first execution mode has central authorities with movable electrode 7, these central authorities with movable electrode 7 with respect to functional unit 9 press direction PD, contact with common electrode 8 with central with fixed contact 6 with central authorities.Thus, operating body 10 by push parts 9, central authorities are pushed with movable electrode 7 and make it to be out of shape with the central authorities of pressing component 11 with press section 11d by central authorities, and can detect to the input operation of pressing direction PD with contacting of fixed contact 6 with central with movable electrode 7 by central authorities.At this moment, limit the periphery that is configured in functional unit 9 by the upper surface 2j of guide wall 2b with pressing component 12 moving to the place ahead direction of pressing direction PD, but because central authorities are embedded in the medium pore 12b of periphery with pressing component 12 with the logical 11a of the portion activity of inserting of pressing component 11, therefore, can move to the place ahead of pressing direction PD (below among the figure) on one side with respect to this medium pore 12b slip on one side.Thus, even the upper surface 2j of guide wall 2b and periphery contact with pressing component 12, functional unit 9 also can move to pressing direction.Thus, not only can carry out input operation, can also carry out to the input operation of pressing direction PD to radial outside.
This is to the input operation of pressing direction PD, because that central authorities form with movable electrode 7 is dome-shaped, therefore produces reaction force on the direction opposite with pressing direction PD, thereby can prevent mistake input.In addition, wanting when pressing direction PD and operate, can to obtain good click feel.
And, described in end to circumferencial direction with when pressing the input operation of direction PD, carry out ensuing input operation for convenience, need make the operating body 10 of functional unit 9 return the initial position that disposes it.At this moment, because multi-way input device 1 has the reset components 14 that produces the recuperability be used to make functional unit 9 reset into described initial position, therefore when carrying out input operation, can carry out input operation from initial position automatically.In addition, because this reset components 14 forms the lid shape of the inside of airtight basket 2, therefore, can prevent that dust or moisture etc. from causing the principal element of misoperation to invade the inside of basket 2.
Since be configured in basket 2 inside and need and periphery that the external component of basket 2 is electrically connected with fixed contact 3, periphery with common electrode 5, central with fixed contact 6 and centrally all form by inlaying with common electrode 8, therefore the number of components of multi-way input device 1 can be reduced, and its assembling procedure can be reduced.In addition, because their leading-out terminal 3a, 5a, leading section 3b, the 5b of 6a, 8a, 6b, 8b separately form different shapes respectively, therefore, when assembling, will seldom cause wrong assembling, thereby can improve the rate of finished products of multi-way input device 1.
That is, to the radial outside direction with when pressing direction PD and carrying out input operation, can when obtaining comfortable operation sense, reduce cost, improve reliability and rate of finished products at the multi-way input device 1 by first execution mode.
(2) second execution modes
As shown in figure 13, in the multi-way input device 1a of second execution mode, use movable electrode 7 and central authorities with the common electrode 8 except guide wall 2b, the periphery of basket 2 with movable electrode 4, central authorities, each parts that are configured among the multi-way input device 1a are identical with the parts of the multi-way input device 1 that is used for first execution mode.Here as shown in figure 13, the periphery that is used for second execution mode is interconnected and forms as one via support 4g with movable electrode 7 with movable electrode 4 and central authorities.Thereby central authorities are not set in second execution mode with common electrode 8 and with its eliminating.In addition, be provided with slit 2k in the part of the guide wall 2b of ring-type, this slit 2k makes and links and the supporting periphery passes through with movable electrode 4 and central support 4g with movable electrode 7.
The following describes the effect of the multi-way input device 1a of second execution mode.
Identical with the multi-way input device 1 of first execution mode, the multi-way input device 1a of second execution mode can carry out to the radial outside and the input operation of pressing direction PD.But, the multi-way input device 1a of second execution mode, because periphery forms one with movable electrode 4 and central authorities with movable electrode 7, so, can detect central thus with fixed contact 6 and central contacting with movable electrode 7 by making central fixed contact 6 and the periphery used with common electrode 5 conductings with central authorities with movable electrode 7 with movable electrode 4 via periphery.Do not need to dispose central authorities' common electrode 8 thus, compare the number of components that to cut down component parts with the multi-way input device 1 of first execution mode, and therefore make the assembling of multi-way input device 1a become easily, and can prevent wrong this multi-way input device of assembling 1a.In addition, can also realize reducing the cost of multi-way input device 1a.
(3) the 3rd execution modes
As shown in figure 14, for additional each following parts in the multi-way input device 1 in the input operation of circumferencial direction, applying secondary input, thereby formed the multi-way input device 1b of the 3rd execution mode at first execution mode.Promptly, as shown in figure 14, the multi-way input device 1b of the 3rd execution mode is identical with first execution mode, have at basket 2: periphery is used for each parts to radial outside input with movable electrode 4 and periphery with common electrode 5 etc. with fixed contact 3 and periphery, central authorities are in central be used for to press each parts that direction import with movable electrode 7 and central authorities with common electrode 8 etc. with fixed contact 6 and central authorities, functional unit 9, lid 13, reset components 14, and limiting part 15, simultaneously periphery possess near with fixed contact 3 second periphery with movable electrode 16 and second periphery with common electrode 17 to be used to carry out secondary input operation to radial outside.Specifically, second periphery uses common electrode 17 by following formation with the movable electrode 16 and second periphery.In addition, for using and the identical parts of multi-way input device 1 of first execution mode, omit it and specify.
Second periphery common electrode 17, as shown in figure 15, integrally formed by inlaying shaping with basket 2, and the part of exposing from the bottom surface 2c in the guide wall of basket 2 outside and each periphery that is in four direction be with fixed contact 3 insulation, and form and cover this each periphery approximate " コ " font with fixed contact 3.This second periphery is with common electrode 17 and be panelized into other contact or the electrode 3 of shape in the inside of basket 2,5,6,8 is identical, each leading-out terminal 17a with the outside that is drawn out to basket 2, the leading section 17b of this leading-out terminal form have can with other leading-out terminal 3a, 5a, 6a, other special shape of 8a phase region.
Extremely shown in Figure 16 as Figure 14, second periphery has with movable electrode 16: to periphery with the outstanding oval dome-type bend 16a of the thickness direction of movable electrode 4 and be formed on bend 16a periphery and with second periphery with common electrode 17 contacted pedestal part 16b, and under initial condition (not carrying out state), be configured to be in movable electrode 4 insulation and covering with fixed contact 3 and periphery each periphery fixed contact 3 of four direction with periphery to the input operation of radial outside.In addition, second periphery is configured to contact with common electrode 17 with second periphery with the pedestal part 16b of movable electrode 16.
The following describes the effect of the multi-way input device 1b of the 3rd execution mode.
Except the input that the multi-way input device 1 by first execution mode carries out, the multi-way input device 1b of the 3rd execution mode also can carry out the secondary input to radial outside.For example, move if the operating body 10 that makes functional unit shown in Figure 14 9 slides to any radial outside, then periphery is pushed periphery with movable electrode 4 and make it to be out of shape with pressing component 12.Like this, periphery contacts with any of movable electrode 16 with second periphery on being configured in four direction with movable electrode 4, thus conducting and this second periphery with movable electrode 16 contacted second peripheries with common electrodes 17 and periphery with common electrodes 5.Thus, multi-way input device 1b can suitably detect the input operation to any radial outside.This is the first order input operation to circumferencial direction.
And, under the state that periphery has contacted with movable electrode 16 with the movable electrode 4 and second periphery, if the operating body 10 that makes functional unit 9 further to this arbitrarily radial outside slide and move, then periphery is further pushed periphery with movable electrode 4 and second periphery usefulness movable electrode 16 that has contacted with movable electrode 4 with periphery with pressing component 12.Like this, second periphery that is pressed contacts with fixed contact 3 with the periphery that is configured in the below with movable electrode 16.Thus, since be connected in periphery with the periphery of movable electrode 4 with common electrode 5 and second periphery with common electrode 17 and periphery fixed contact 3 conductings, the input operation of carrying out to radial outside so multi-way input device 1b can detect further pushing after the input operation of circumferencial direction of the first order.This is partial input operation to radial outside.Different with the input operation to radial outside of the first order, this partial input operation to radial outside forms dome-type second periphery and has click feel with movable electrode 16 by pushing, and therefore can prevent the misoperation to the secondary input of radial outside.In addition, when carrying out, can be accompanied by good and brisk click feel and operate to the input operation of the second level of radial outside.
That is, the multi-way input device 1b of the 3rd execution mode is in the input operation of radial outside, can carry out the secondary input on the direction pushing, thereby can obtain the effect of the convenience that improves multi-way input device 1b.
(4) the 4th execution modes
As shown in figure 17, the multi-way input device 1c of the 4th execution mode is identical with first execution mode, has at basket 2: periphery with fixed contact 3 and periphery with movable electrode 4 and periphery with common electrode 5 etc. be used for each parts, central authorities to the circumferencial direction input with fixed contact 6 and central authorities with movable electrode 7 and centrally be in central being used for to pressing each parts, functional unit 9, lid 13, reset components 14 and the limiting part 15 that direction is imported with common electrode 8 etc.Here different with the multi-way input device 1 of first execution mode is, the guide wall 2b of basket 2 is formed has the height of not using pressing component 12 contacted degree with periphery, and central authorities are formed in movable electrode 7 and central authorities have pit 7c with the contacted part of press section 11d.
Different with the multi-way input device 1 of first execution mode, when circumferencial direction carries out input operation, have described guide wall 2b and central authorities and can move rather than slip is moved and carried out its input operation by pushing over the multi-way input device 1c of the 4th execution mode of movable electrode 7.Specifically, if push over operating operation parts 9 to radial outside, then functional unit 9 is pivot point with press section 11d and central authorities with the point of contact of the pit 7c of movable electrode 7 with central authorities, and the lid 13 and first execution mode in the same manner with periphery with pressing component 12 be restricted to be free to slide to circumferencial direction mobile, therefore, periphery can push in movable electrode 4 pushing periphery with pressing component 12.Thus, the multi-way input device 1c of the 4th execution mode not only can carry out moving and the input operation to circumferencial direction carried out as the slip by operating body 10 of the multi-way input device 1 of first execution mode, also can carry out the input operation of being undertaken by pushing over of operating body 10 to radial outside as the multi-way input device 1c of the 4th execution mode.
(5) the 5th execution modes
The multi-way input device of the 5th execution mode is identical with first execution mode, has at basket 2: periphery is in central be used for to press each parts that direction import with movable electrode 7 and central authorities with common electrode 8 etc. with fixed contact 6 and central authorities with each parts, central authorities that common electrode 5 etc. is used for to the circumferencial direction input with movable electrode 4 and periphery with fixed contact 3 and periphery.Here multi-way input device 1 difference with first execution mode is, as the lid 113 of lower member, reset components 114 and as the limiting part 15 of upper member in advance by integrated, thereby be used as a cover and by blocking.
Reset components 114 forms the identical profile of profile size that has with limiting part 115, and be formed with locator protrusions 114e and locator protrusions 114f in four bights, the location division of the gulde edge tabling of described locator protrusions 114e conduct and limiting part 115 and be formed on upper surface up, described locator protrusions 114f is formed on lower surface down as the location division of the inserting hole 113b that is embedded into lid 113.And, in the present embodiment, the effect of described locator protrusions 114f is, will be by blocking cover when being installed to basket 2, the described periphery that is housed among the described maintaining part 2e is pressed on maintenance face 2f and periphery with common electrode 5 (with reference to Figure 20) with the maintained portion 4a of movable electrode 4.
