POSITION SENSING DEVICE AND POSITION SENSING METHOD
First Claim
1. A position sensing device comprising:
- at least one light receiver that receives lights that are emitted from a plurality of light exit positions of a scanning light source component to scan a predetermined area and are reflected by a sensing object within the predetermined area; and
a processor that controls the scanning light source component, and senses position of the sensing object based on a light reception signal of the light receiver,the processor further determining from which of the lights the light reception signal is obtained, and sensing the position of the sensing object based on optical paths of the lights.

Abstract
A position sensing device includes at least one light receiver, and a processor. The light receiver receives lights that are emitted from a plurality of light exit positions of a scanning light source component to scan a predetermined area and are reflected by a sensing object within the predetermined area. The processor controls the scanning light source component, and senses position of the sensing object based on a light reception signal of the light receiver. The processor further determines from which of the scanning lights the light reception signal is obtained, and senses the position of the sensing object based on optical paths of the scanning lights.
