O type circle 17 is made of the silicone rubber elastomeric material, and forms section as shown in Figure 6 and be slightly circular ring-type.O type circle 17 is stored as described above in being formed at the 3C of concavity portion at the flange part 3D back side, but, under the state of having assembled each parts, by be formed on rotary body 5 upper surfaces a plurality of slot part 5C and with the back side (3C of concavity portion) of the opposed flange part 3D of this slot part 5C with given load by the Elastic Contact clamping, as shown in figure 18, become the state that is crushed.Therefore, the upper surface that forms rotary body 5 is to produce frictional force between the face of slot part 5C and the O type circle 17 and between the back side (3C of concavity portion) of flange part 3D and the O type circle 17.Frictional force is set to, and the face of the slot part 5C of formation rotary body 5 and the frictional force between the O type circle 17 are less than the back side of flange part 3D and the frictional force between the O type circle 17.And O type circle 17 can not be crushed till being adjacent to slot part 5C bottom surface, and forms small gap S between the slot part 5C of O type circle 17 and rotary body 5 upper surfaces, prevents that by this gap S O type circle 17 is drawn onto the upper surface of rotary body 5.
The functional unit 20 that is rotated operation forms operating axis 2 and lug installation portion 1 by incorporate structure.Operating axis 2 for example is metallic and forms cylindrical shape shown in Figure 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, summary upper section at driving body fastener 2A is formed for embedding the slip-off preventing concavity 2C of portion that prevents to come off with circle 10, and on parts of bearings 3, insert after the logical operating axis 2, by insert 10 on the slip-off preventing concavity 2C of portion, make operating axis 2 prevent to come 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 constitutes 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.Form mounting panel 8 by stamped sheet metal, and as shown in figure 16, be formed for inserting the peristome 8A that axis holds the big footpath cylindrical portion 3B of parts 3, form the 8B of pair of curved portion respectively in the left and right sides of mutual opposed side plate, and form the snap-fastener 8C of portion.When assembling, dividing plate 7 is configured in the below of insulation booth 4, and makes big footpath cylindrical portion 3B insert logical peristome 8A, mounting panel 8 is configured in 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 fixed by dividing plate 7 and mounting panel 8 clampings.In assembled as described above rotary coder, insulation booth 4 overcomes the elastic force of O type circle 17 pushes the upper side of rotary body 5 in Fig. 3, thereby makes O type circle 17 strains.Promptly, as Fig. 3 and shown in Figure 180, the upper surface of the rotary body 5 of the O type circle 17 in the rotary coder by forming a plurality of slot part 5C 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 Elastic Contact ground clamping.In addition, when the rotary coder of present embodiment was installed on circuit board, the 8C of snap-fastener portion was pressed in the installing hole that not have circuit board that shows in the accompanying drawing, thus with rotary coder to the assigned address location and bring into play the effect that comes off of preventing.
Secondly, will the effect of present embodiment be described.When not having in by the accompanying drawing that is embedded into lug installation portion 1 the operation lug that shows to assigned direction rotary actuator 20, 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 rotations, 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 are alternately sliding on the peristome 18A of encoding board 18 and on the 18B of contact portion respectively simultaneously.Thus, alternately becoming conducting, nonconducting state between portion of terminal 14A and the portion of terminal 13A and between portion of terminal 14A and the portion of terminal 15A respectively, 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, and O type circle 17 is crushed under the 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 the O type circle 17 and between the back side and O type circle 17 of flange part 3D.And, be set at the face of a plurality of slot part 5C that form rotary body 5 and the frictional force between the O type circle 17 less than the back side of flange part 3D and the frictional force between the O type circle 17.Therefore, certain torque is in the rotation of rotary body 5, thereby makes the operator of operating operation parts 20 feel certain weight (load).At this moment, because with the contact portion of the O type circle 17 of rotary body 5 on form a plurality of slot part 5C, and between the bottom surface of O type circle 17 and each slot part 5C, form small gap S, so under the situation that O type circle 17 is not drawn onto on the rotary body 5, rotate sleekly while rotary body 5 produces frictional force.That is, do not produce the sensation of bumping firmly because of frictional resistance changes rapidly, rotary body 5 is rotation stably 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 Elastic Contact ground clamping O type circle 17, 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 rotary body 5 and make frictional resistance become big, thereby can make functional unit 20 stably keep the appointment torque with a plurality of slot part 5C.And the frictional resistance that can suppress between O type circle 17 and rotary body 15 upper surfaces becomes big, so there is no need between coating lubricant, can also prevent to be subjected to the influence that O type circle 17 that lubricant causes expands and to operate sense of touch uneven.
And, in one embodiment of the invention, form a plurality of slot part 5C with concentric circles ground at the upper surface of rotary body 5.So, at the rotary manipulation along with functional unit 20, under the situation that the upper surface slide of O type circle 17 and the rotary body 5 with a plurality of slot part 5C contacts, O type circle 17 is difficult to distortion, so functional unit 20 and rotary body 5 are stably rotated, thereby can access good operation sense of touch.
And in one embodiment of the invention, the upper surface and the frictional force between the O type circle 17 that have formed the rotary body 5 of a plurality of slot part 5C are set to less than the back side of flange part 3D and the frictional force between the O type circle 17.Thus, when rotary manipulation during functional unit 20, just be difficult to produce sliding contact between flange part 3D that frictional force is big and the O type circle 17, produce 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.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 clamping of the flange part 3D of the parts of bearings 3 that O type circle 17 forms by the upper surface of the rotary body 5 that is formed by resin material with by metal materials such as aluminium die casting, and on the upper surface of rotary body 5, formed a plurality of slot part 5C.Here, the frictional force between the upper surface of O type circle 17 and rotary body 5 is set for less than the frictional force between the back side of O type circle 17 and flange part 3D, so between O type circle 17 and parts of bearings 3, slide hardly.Therefore, even on parts of bearings 3, use metal material, also can suppress to produce the abrasion of O type circle 17, and because with the upper surface of the rotary body 5 of O type circle 17 sliding contacts be resin material, so can realize the long lifetime of rotary type electric parts (rotary coder).
And, in one embodiment of the invention, form the ring-type concavity 3C of portion that deposits O type circle 17 at the back side of the flange part 3D of parts of bearings 3.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 Elastic Contact and clamping O type circle 17 reliably, thereby it is uneven to suppress torque more reliably.
And, in one embodiment of the invention, between the bottom surface of O type circle 17 and 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 big.Therefore, functional unit 20 and rotary body 5 are more stably rotated with the torque of appointment, can obtain good operation sense of touch.
In addition, the present invention is not limited to above-mentioned execution mode, for example can carry out following distortion and implement, and these execution modes also belong to technical scope of the present invention.
