Abstract
A reflector that is used for adjusting a radiation direction of a radiation unit in a position detection apparatus that performs a process based on a detected position of reflected light of light radiated from the radiation unit includes a first reflection surface that reflects the light radiated from the radiation unit, and a second reflection surface that intersects with the first reflection surface and reflects the light radiated from the radiation unit.
Claims6
A reflector that is used for adjusting a radiation direction of a radiation unit in a position detection apparatus that performs a process based on a detected position of reflected light of light radiated from the radiation unit, the reflector comprising:
- a first reflection surface that reflects the light radiated from the radiation unit;
- and
- a second reflection surface that intersects with the first reflection surface and reflects the light radiated from the radiation unit.
An adjustment method that is used for adjusting a radiation direction of light from a radiation unit in a position detection apparatus that performs a process based on a detected position of reflected light formed by reflection of the light radiated from the radiation unit from a reflector, the method comprising:
- using a reflector including a first reflection surface that reflects the light radiated from the radiation unit, and a second reflection surface that intersects with the first reflection surface and reflects the light radiated from the radiation unit as the reflector;
- detecting a position of light reflected from the reflector;
- and
- adjusting the radiation direction based on the detected position of the reflected light.
A position detection apparatus comprising:
- a detection unit that detects a position of light reflected from a reflector including a first reflection surface that reflects light radiated from a radiation unit, and a second reflection surface that intersects with the first reflection surface and reflects the light radiated from the radiation unit;
- a determination unit that determines whether the position of the reflected light detected by the detection unit is on the first reflection surface or the second reflection surface;
- and
- an output unit that outputs information according to the determination result from the determination unit.
