< 3. adopts the effect example > of present embodiment
The scrambler 100 of present embodiment as described above, this scrambler has encoder main body 110 and covers the cover 120 of this encoder main body 110, when making this scrambler miniaturization, need to reduce encoder main body 110 and the gap of covering between 120.On the other hand, because cover 120 is formed by conductive material, thereby need to guarantee the insulation distance between encoder main body 110 and cover 120.By guaranteeing fully insulation distance, can reduce the influential noise of the function of scrambler 100.
At this, when the inside at cover 120 arranges certain distribution component (being distribution component 118 in the present embodiment), in order to avoid disk 111 or substrate 112 etc., possible distribution component makes the outer circumferential side of encoder main body 110 approach (or contact) cover 120 and configures.Therefore, when switching on to distribution component, thereby at it and have between the cover 120 of electric conductivity generation stray capacitance is caused to voltage (so-called electrostatic coupling), these will become the former of noise etc. thereby likely hinder the raising of scrambler 100 functions.Therefore, as in this embodiment, by at least insulating material 131 being set between distribution component 118 and cover 120, even if reduce the gap between distribution component 118 and cover 120, also above-mentioned electrostatic coupling can be prevented, thereby scrambler 100 miniaturizations can be under the state of function that does not affect scrambler 100, made.Its result, can keep the reliability of scrambler 100 and can make its miniaturization fully.
In addition, adopt present embodiment can access following effect.That is,, for scrambler 100, for example, owing to connecting the wire 115 of scrambler 100 with control device CT and be configured to approach the power line (omitting diagram) etc. of motor M, thereby may there is noise to enter in scrambler 100 by wire 115.This noise is passed to distribution component 118 by substrate 112C, by electrostatic coupling etc., by distribution component 118, to cover 120, is exerted an influence, and likely hinders the raising of scrambler 100 functions.To this, as in this embodiment, by insulating material 131 is set, can prevents the interaction between above-mentioned distribution component 118 and cover 120, thereby can improve scrambler 100 for the tolerance of noise.
In addition, especially in the present embodiment, distribution component 118 is for powering to light-emitting component 116.For the distribution component 118 of this purposes and cover 120, approach while configuring (or contact), likely hinder the raising of scrambler 100 functions.As its reason, in the time of can expecting to light-emitting component 116 power supply, mobile electric current is exerted an influence to cover 120 by distribution component 118 by electrostatic coupling etc., and to substrate 112 etc., exerts an influence by covering 120 again.In addition, also can expect distribution component 118 and cover 120 between because electrostatic coupling produces electric discharge, thereby make to the power supply instability of light-emitting component 116.To this, as in this embodiment by insulating material 131 is set, can prevent the interaction between above-mentioned distribution component 118 and cover 120, thus can be stably to light-emitting component 116 power supplies.
In addition, especially in the present embodiment, due to distribution component 118 have flexible, can be easily in the inside solderless wrapped connection of cover 120.In addition, because the distance between the substrate 112 connecting by distribution component 118 and light-emitting component 116 is unfixing, so can improve the design freedom of scrambler 100.In addition, when employing has flexible distribution component 118, can distribution component 118 be improved with cover 120 possibilities that more approach (or contact) by deflection etc., thereby make the insulating material that is arranged on distribution component 118 and covers between 120 have good effect.
In addition, especially in the present embodiment, insulating material 131 is mainly arranged between distribution component 118 and cover 120.So, the position emphasis of the maximum reason that can improve in the function of the obstruction scrambler 100 of expecting arranges insulating material 131, thereby can effectively prevent the interaction between distribution component 118 and cover 120.In addition, can reduce the use amount of insulating material 131, can also reduce simultaneously insulating material 131 man-hour used is set.
In addition, especially in the present embodiment, the structure that makes scrambler 100 is so-called infiltration type scrambler.Now, because photo detector 117 is arranged on substrate 112A above, light-emitting component 116 is configured in the position of leaving substrate 112, thereby makes the solderless wrapped connection distance of the distribution component 118 of connection substrate 112C and light-emitting component 116 become longer.Like this, can distribution component 118 be improved with cover 120 possibilities that more approach (or contact) by deflection etc., thereby make set insulating material 131 have good effect.
