Also have, protuberance 3j also is embedded in the insulating body 1, and the cut-out portion of protuberance 3j is in from the 2nd and the 3rd lateral margin 1h, the state that 1j exposes.
Have again, in conducting wiring pattern 2,3, joint portion 19 shown in the double dot dash line in manufacturing step among Fig. 1 is provided with according to the mode of the inside that is positioned at recess 1c, by this joint portion 19, and the conducting wiring pattern 2 of adjacency, 3 the 2c of inner peripheral portion, the two ends of 3e connect, and cut off this joint portion 19 by the position at recess 1c, form the cut-out 2d of portion, 3f, by cutting off joint portion 19, will cut between the conducting wiring pattern 2,3 that adjoin each other.
In addition, the 2a of contact portion in conducting wiring pattern 2,3, on the insulating body 1 that 3b exposes on the surface of insulating body 1 in the form of a ring, as shown in Figure 3, by the support 4a among the embedded hole 1a, not with the 2d of cut-out portion, under the contacted situation of 3f, rotatably keep rotary body 4, can successfully rotate this rotary body 4, thereupon, the contact chip (not shown) that is installed on the rotary body 4 is slided on conducting wiring pattern 2,3, produce required pulse.
Below according to Fig. 4～6, the manufacture method of the insulating body 1 of such rotary coder is described, as shown in Figure 4, by transfer port 11a, transmit hoop spare 11 successively, this hoop spare 11 is carried out punch process, formation is along a base portion 12 of the linearity of the direction of transfer A of hoop spare 11; Two lattice bar portions 13, this two lattice bar portions 13 along with the perpendicular direction of this base portion 12, extend abreast; Wiring pattern group 14, this wiring pattern group 14 is formed by a plurality of conducting wiring patterns 2,3, and this conducting wiring pattern 2,3 is formed at by above-mentioned base portion 12 and two intervals that lattice bar portion 13 is surrounded in die-cut mode; A pair of connecting portion 16, this, is connected the both sides of the direction of transfer A of wiring pattern group 14 in the width H of the diameter of the annulus 15 of this wiring pattern group 14 scope connecting portion 16 with lattice bar portion 13.
In addition, in wiring pattern group 14, form the notch 17 that is arranged between the wiring pattern 2,3 that adjoins each other; Breach hole 18 in the middle of being arranged at; Joint portion 19, this joint portion 19 be at the 2c of inner peripheral portion, the end of 3e, and the 2c of inner peripheral portion that will form by this breach hole 18,3e, and the 2c of this inner peripheral portion relatively, 3e is outstanding towards central side, and the conducting wiring pattern 2,3 of adjacency connects; The 3b of contact portion, it is formed with a plurality of through hole 3a; Portion of terminal 2b, 3h, this portion of terminal 2b, 3h according on base portion 12 side by side and the die-cut formation of ways of connecting.
Then, will be sent in the electroplating bath, afterwards, as shown in Figure 5,, on hoop spare 11, form insulating body 1 by the processing that is shaped according to the hoop spare 11 that mode shown in Figure 4 is processed.
Then, by the processing of this insulating body 1, at pars intermedia, form hole 1a and recess 1c, this recess 1c extends towards foreign side from hole 1a, and joint portion 19 is in the state that is positioned at this recess 1c.
Afterwards, after forming insulating body 1, as shown in Figure 6, at first, joint portion 19 is cut off, then, with portion of terminal 2b, 3h and base portion 12 cut, then to portion of terminal 2c, 3h carries out bending machining, at last, connecting portion 16 is cut off, when insulating body 1 is cut with hoop spare 11, finish manufacturing, obtain the encoding board of rotary coder shown in Fig. 1～3.
Also have, in the present embodiment, by joint portion 19, the conducting wiring pattern of the adjacency in the both ends of maintenance inner peripheral portion, its periphery remains on the hoop spare by connecting portion and portion of terminal, therefore under the situation of load application, the danger that deforms is arranged seldom.
Have again, in the present embodiment, after plating, form, still, also can after shaping, electroplate.
In addition, Fig. 7 represents another embodiment of rotary coder of the present invention, present embodiment is the rotary coder that has push switch, push switch 20 is formed by support 21 and button 22 etc., admitting in this support 21 has fixed contact, the movable contact (not shown), and this button 22 is installed on this support 21 in mode moving up and down, this push switch 20 is installed on the insulating body 1 by the installation portion 1f of insulating body 1.
In addition, the rotary body 24 that contact chip 23 is installed is by installing component 25, rotatably be installed on the insulating body 1, and the central part in this rotary body 24, axially displaceable operating axis 26 is installed, and this operating axis 26 is provided with the 26a of rotation stopping portion, and it passes the hole 1a in the insulating body 1, and 1c is chimeric with recess, stops the rotation of operating axis 26.
Also have, if rotation is installed on and handles knob 27 on the rotary body 24, then contact chip 23 is at conducting wiring pattern 2, slide on 3, produce pulse, in addition, if push the functional unit 28 that is installed on the operating axis 26, then by operating axis 26, pressing button 22, carry out the switching of the contact of push switch 20, in addition, when removing the pushing of functional unit 28, by the elastic force of push switch 20 sides, button 22, operating axis 26 and functional unit 28 return to reset condition.
When this pressing operation, because the 26a of rotation stopping portion and the recess 1c of operating axis 26 are chimeric, operating axis 26 is not rotated action, and operability is good.
Have again, at this moment since operating axis 26 not with the 2d of cut-out portion, 3f contacts, so can carry out level and smooth pressing operation.
In rotary coder of the present invention, owing to be positioned at conductive wiring diagram case 2, the 2c of inner peripheral portion of hole 1a one side in 3, the end of 3e is provided with the conducting wiring pattern 2 with adjacency, the 2d of cut-out portion that cuts between 3,3f, the 2c of this inner peripheral portion, 3e is from the inner face of the hole 1a of insulating body 1, along outward direction, be arranged at disengaged position, and the 2d of cut-out portion, the inner face of the hole 1a of 3f from insulating body 1 exposes, so state in week in being supported on by joint portion 19, conducting wiring pattern 2,3 can be embedded in the insulating body 1, conducting wiring pattern 2,3 do not bend, distortion can be arranged at on the one side, and availability can be good, cost is lower, rotary coder easy to manufacture.
In addition, since the 2d of cut-out portion, the relative inner peripheral 2c of portion of 3f, 3e, side-prominent towards central part, so with the 2c of inner peripheral portion, 3e is embedded in the state in the insulating body 1, can form the 2d of cut-out portion, 3f, it is easy to manufacture, and can form rotary body 4 and the 2d of cut-out portion, the discontiguous structure of 3f, the rotary coder that can provide rotary body 4 to rotate smoothly.
In addition, because conducting wiring pattern 3 comprises a plurality of through hole 3a that are formed on the same radius; A plurality of contact 3b of portion between this through hole 3a; Outside connecting portion 3c, this outside connecting portion 3c connect a plurality of contact 3b of portion in the position in the outside of radial direction; Inboard connecting portion 3d, this inboard connecting portion 3d will connect between a plurality of contact 3b of portion at the inner side along radial direction, thus can provide the supporting of the 3b of contact portion certain, unbending conducting wiring pattern 3.
Also have, because outside connecting portion 3c, inboard connecting portion 3d is embedded in the insulating body 1, so really conducting wiring pattern 3 is installed in the insulating body 1 by outside support 1e and inboard support 1d.
