The first pattern includes first and second unit regions. The first unit regions guide the light from light emission unit to the light receiving unit. The second unit regions are configured not to guide light from the light emission unit to the light receiving unit. The second pattern includes first and second unit regions. The first unit regions of the second pattern guide light from light emission unit to the light receiving unit. The second unit regions of the second pattern are configured not to guide light from the light emission unit to the light receiving unit. The first and second unit regions of the first pattern are reverse to the first and second unit regions of the second pattern in a direction perpendicular to a rotation direction of the rotatable plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoder using rotatable plate, light source and light receiver","description":"An encoder includes rotatable plate including first and second patterns, light emission unit, and light receiving unit.
