1. An image sensing apparatus comprising:

  • a first light-emitting element for emitting a first signal light;

    an opening for leading the first signal light, which is emitted by said first light-emitting element, to the exterior of a case, and for introducing sensed light from a subject into the interior of the case and a second signal light emitted by a second light-emitting element from the exterior into the interior of the case;

    an image sensing lens for receiving, within the interior of the case, the sensed image light from the subject that as entered the interior of the case via said opening; and

    optical bending device for bending the optical path of the sensed light from the subject and the optical path of the signal lights;

    wherein said optical path bending device comprises at least two mirrors coupled to one another and disposed on the same plane; and

    wherein after the bending of the optical path by said optical path bending device is performed, the sensed light from the subject is received by said image sensing lens and the first signal light from said first light-emitting element is led to the exterior of the case via said opening, and has an optical path substantially parallel to said second signal light.
