1. An input device configured to communicate with an information processing device, the input device comprising:
a light source unit configured to emit light;
a case including:
a first surface including a first opening and configured to emit the light toward a target object through the first opening; and
a second surface including a second opening and configured to emit the light toward a living body through the second opening;
a first light reception unit configured to receive first light from the target object through the first opening of the first surface;
a second light reception unit configured to receive second light from the living body through the second opening of the second surface; and
a deflection unit configured to deflect one part of the light and transmit another part of the light, wherein
the deflection unit deflects the one part of the light emitted from the light source unit toward the first opening of the first surface, and transmits the another part of the light emitted from the light source unit toward the second opening of the second surface,
the light emitted from the light source unit includes light having a first wavelength and light having a second wavelength different from the first wavelength,
the deflection unit deflects the light having the second wavelength toward the target object and deflects the light having the first wavelength toward the living body,
the light emitted from the light source unit includes light having a third wavelength longer than the first wavelength,
the deflection unit deflects the light having the third wavelength toward the living body, and
the second light reception unit includes a first light reception member configured to receive the light having the first wavelength and a second light reception member configured to receive the light having the third wavelength.
