The functional unit 20 that is rotated operation forms the structure that operating axis 2 and lug installation portion 1 are integrated.Operating axis 2 is for example metal system and forms the cylindrical shape shown in Fig. 5.The bottom of aforesaid operations axle 2 forms the corner post shape of taper and becomes the driving body fastener 2A of the axle fitting portion 6A that embeds driving body 6.The upper end of operating axis 2 forms semi-cylindrical and becomes the fastener 2B that lug installation portion 1 embeds.And, at the summary upper section of driving body fastener 2A, be formed for embedding and prevent the slip-off preventing concavity 2C of portion that comes off with circle 10, and insert logical operating axis 2 on parts of bearings 3 after, by insert 10 on the slip-off preventing concavity 2C of portion, make operating axis 2 be prevented from coming off by the lower edge of path cylindrical portion 3A.
And, in order to assemble insulation booth 4 and the parts of bearings 3 that forms shell, dividing plate 7 and mounting panel 8 are set.Dividing plate 7 is configured in the downside of insulation booth 4, and mounting panel 8 is configured in the top of parts of bearings 3.By stamped sheet metal, form mounting panel 8, and as shown in figure 16, be formed for inserting the peristome 8A of the large footpath cylindrical portion 3B that leads to parts of bearings 3, in the left and right sides of mutual opposed side plate, form respectively the 8B of pair of curved portion, and form by buckle portion 8C.When assembling, dividing plate 7 is configured in to the below of insulation booth 4, and large footpath cylindrical portion 3B is inserted open up oral area 8A, mounting panel 8 to be configured in to the top of parts of bearings 3.By each bend 8B is crooked to the inside at the back side of dividing plate 7, insulation booth 4 and parts of bearings 3 are clamped and are fixed by dividing plate 7 and mounting panel 8.In assembled as described above rotary coder, insulation booth 4 overcomes the elastic force of O type circle 17 to be pressed rotary body 5 to the upper side in Fig. 3, thereby makes O type circle 17 strains.; as shown in Fig. 3 and Figure 18; O type circle in rotary coder 17 by form a plurality of slot part 5C rotary body 5 upper surface and with the back side (3C of concavity portion) of the flange part 3D of the opposed parts of bearings 3 of this upper surface, with given load by the elastic connecting clamping of contacting to earth.In addition, when the rotary coder of present embodiment is installed on circuit board, by buckle portion 8C, be pressed in the installing hole of the circuit board that there is no demonstration in accompanying drawing, thereby rotary coder is prevented to the effect coming off to assigned address location and performance.
Secondly, by the effect of explanation present embodiment.When by being embedded into while not having the operation lug that shows to assigned direction rotary actuator 20 in the accompanying drawing of lug installation portion 1, revolving force is communicated to rotary body 5 by driving body 6 grades.Therefore, rotary body 5 is along the direction of rotation rotation of functional unit 20.When rotary body 5 rotation, contact site 14B, the 14C of self-cleaning contact parts 14 slides on the ring-type contact 18C of portion of encoding board 18, and contact site 13B, the 15B of self- cleaning contact parts 13,15 alternately slide on the peristome 18A of encoding board 18 and on the 18B of contact portion respectively simultaneously.Thus, alternately becoming respectively conducting, nonconducting state between portion of terminal 14A and portion of terminal 13A and between portion of terminal 14A and portion of terminal 15A, is the rectangular pulse signal of 90 degree thereby make portion of terminal 13A and portion of terminal 15A phase difference output.
As mentioned above, insulation booth 4 and parts of bearings 3 are gripped by dividing plate 7 and mounting panel 8, make thus O type circle 17 be crushed under given load effect.Therefore,, when rotary body 5 rotation, frictional force acts between face that the upper surface that forms rotary body 5 is a plurality of slot part 5C and O type circle 17 and between the back side and O type circle 17 of flange part 3D.And, be set as forming face and the back side that the frictional force between O type circle 17 is less than flange part 3D and the frictional force between O type circle 17 of a plurality of slot part 5C of rotary body 5.Therefore, certain torque is in the rotation of rotary body 5, thereby makes the operator of operating operation parts 20 feel certain weight (load).Now, because form a plurality of slot part 5C in the contact portion of the O type circle 17 with rotary body 5, and form small gap S between O type circle 17 and the bottom surface of each slot part 5C, so in the situation that O type circle 17 is not drawn onto on rotary body 5, rotate sleekly while rotary body 5 produces frictional force.That is, because frictional resistance changes rapidly, do not produce the sensation of firmly touching, rotary body 5 is stably rotation under certain torque.
As described above, in one embodiment of the invention, the upper surface of rotary body 5 and and the back side of the opposed parts of bearings 3 flange part 3D of this upper surface between the elastic connecting clamping O type circle 17 that contacts to earth, and form a plurality of slot part 5C at the upper surface of rotary body 5.Thus, can control O type circle 17 and inhale on the upper surface that is attached to the rotary body 5 with a plurality of slot part 5C and make frictional resistance become large, thereby can make functional unit 20 stably keep appointment torque.And, can suppress frictional resistance between O type circle 17 and rotary body 15 upper surfaces and become large, so there is no need between coating lubricant, can also prevent from being subject to the impact that O type circle 17 that lubricant causes expands and that operation feeling occurs is uneven.
And, in one embodiment of the invention, the upper surface of rotary body 5 with concentric circles form a plurality of slot part 5C.So, at the rotary manipulation along with functional unit 20, in the situation that O type circle 17 contacts with the upper surface slide with the rotary body 5 of a plurality of slot part 5C, O type circle 17 is difficult to distortion, so can make functional unit 20 and rotary body 5 stably rotate, thereby can access good operation feeling.
And, in one embodiment of the invention, formed the upper surface of rotary body 5 of a plurality of slot part 5C and the frictional force between O type circle 17 and be set to and be less than the back side of flange part 3D and the frictional force between O type circle 17.Thus, when rotary manipulation during functional unit 20, between the flange part 3D that frictional force is large and O type circle 17, be just difficult to produce sliding contact, between the upper surface of the rotary body 5 of the main and a plurality of slot part 5C of formation that frictional force is little of the sliding contact of O type circle 17, produce.For this reason, the object of O type circle 17 main sliding contacts is specified in a side (upper surface of rotary body 5), thus can reduce the principal element that produces torque deviation, thus can obtain deviation stable torque still less.
And, in one embodiment of the invention, the back side of the flange part 3D of the upper surface of the rotary body 5 that O type circle 17 is formed by resin material and the parts of bearings 3 being formed by metal materials such as aluminium die casting clamps, and on the upper surface of rotary body 5, has formed a plurality of slot part 5C.Frictional force between O type circle 17 and the upper surface of rotary body 5 is set for to the frictional force being less than between O type circle 17 and the back side of flange part 3D, so slide hardly here, between O type circle 17 and parts of bearings 3.Therefore, even use metal material on parts of bearings 3, also can suppress to produce the abrasion of O type circle 17, and be resin material because of the upper surface of the rotary body 5 with 17 sliding contacts of O type circle, so can realize the long lifetime of rotating type electric component (rotary coder).
And, in one embodiment of the invention, at the back side of the flange part 3D of parts of bearings 3, form the ring-type concavity 3C of portion that deposits O type circle 17.Therefore, can very accurately determine the position of O type circle 17, thus can and formed between the upper surface of rotary body 5 of a plurality of slot part 5C reliably Elastic Contact and clamped O type circle 17, thereby it is uneven to suppress more reliably torque.
And, in one embodiment of the invention, between O type circle 17 and the bottom surface of each slot part 5C, form small gap S.Thus, by small gap S, can prevent reliably that 17 suctions of O type circle are attached to the upper surface of the rotary body 5 with a plurality of slot part 5C and make frictional resistance become large.Therefore, can make functional unit 20 and rotary body 5 more stably rotate with the torque of appointment, can obtain good operation feeling.
