Abstract
An encoder includes a first substrate including a point light source that emits light onto reflective slits formed on a disc and a light-receiving element that receives light emitted from the point light source and reflected by the reflective slits, a second substrate onto which the first substrate is mounted, a lustrous connecting portion configured to electrically connect the first substrate and the second substrate, and a covering material configured to cover the connecting portion in the manner that the point light source and the light-receiving element are exposed.
Claims5
An encoder comprising:
- a first substrate comprising a point light source that emits light onto reflective slits formed on a disc, and a light-receiving element that receives light emitted from the point light source and reflected by the reflective slits;
- a second substrate onto which the first substrate is mounted;
- a lustrous connecting portion configured to electrically connect the first substrate and the second substrate;
- and
- a covering material configured to cover the connecting portion in the manner that that the point light source and the light-receiving element are exposed.
A servo motor comprising:
- a motor configured to rotate a shaft;
- and
- an encoder configured to detect a position of the shaft,
- the encoder including:
- a first substrate comprising a point light source that emits light onto a reflective slits formed on a disc connected to the shaft, and a light-receiving element that receives light emitted from the point light source and reflected by the reflective slits;
- a second substrate onto which the first substrate is mounted;
- a lustrous connecting portion configured to electrically connect the first substrate and the second substrate;
- and
- a covering material configured to cover the connecting portion in the manner that the point light source and the light-receiving element are exposed.
