The inclined surface 120a for penetrating portion 120 is reflected towards the direction different from reflection sensor 100.Therefore, it is able to suppress reflex sensing
Device 100 detect by installing pipe 110 across spun yarn 10 channel with and reflection sensor 100 opposed position reflection
This case that light.Thus, reflection sensor 100 can suitably detect the light reflected by spun yarn 10, can reliably detect
There is the spun yarn 10 for the attraction of suction pipe 44 of having no way of.
It is inhibited with the light of external reflectance by the detection this case of reflection sensor 100 by spun yarn 10, it can be using instead
It penetrates formula sensor 100 and detects the light only reflected by spun yarn 10.Therefore, even if enhancing light projected etc. and improving reflection sensor
100 transducer sensitivity also can suitably detect spun yarn 10.
The position opposed with reflection sensor 100 in installing pipe 110 is provided with hole 110b.From reflection sensor
The light that 100 sensor cover 100a is projected is projected via hole 110b towards installing pipe 110 outside.By like this will be from sensor cover
The light that 100a is projected can not be restricted by the thickness of installing pipe 110 towards guidance outside installing pipe 110 and improve setting reflecting part
The freedom degree of 120 position.Also, it is difficult to be again incident on via the hole 110b of installing pipe 110 by the light that reflecting part 120 reflects
The sensor cover 100a of reflection sensor 100.Reflection sensor 100 can be detected suitably and be reflected by spun yarn 10 as a result,
Light.
It, can easily will be from the sensor of reflection sensor 100 since reflecting part 120 has inclined surface 120a
The light that face 100a is projected is reflected towards the direction different from reflection sensor 100.As a result, in the (reflection of the back side of reflecting part 120
Portion 120 with 100 side opposite side of reflection sensor), without the reflection of light for considering to project from reflection sensor 100, energy
Enough configure other component.
Even if also, for example, reflecting part so that being incident to the mode of reflection sensor 100 by the light that reflecting part reflects
