Abstract
According to one embodiment, an imaging device array includes a plurality of imaging devices integrally including an incidence surface that converges light in the primary scanning direction, plural reflective surfaces that reflect light from the incidence surface multiple times, and an exit surface through which light that has reflected at the plural reflective surfaces exits the array. At least one of the plural reflective surfaces is formed at the apex of a protrusion that protrudes outwardly from the surface of the array, and the light that is output from the exit surface is imaged at an image point.
Claims20
An imaging device array for an imaging apparatus having a primary and a secondary scanning direction comprising:
- a plurality of imaging devices integrally including an incidence surface that converges light in the primary scanning direction;
- a plurality of reflective surfaces that reflect light from the incidence surface multiple times;
- and an exit surface that outputs light that has gone through the plurality of reflective surfaces;
- wherein
- in the imaging device, at least one of the plurality of reflective surfaces is formed on the apex of a protrusion, and the light that exits the imaging device at the exit surface is imaged at an image point.
An imaging device array comprising:
- a plurality of imaging devices integrally including a lens surface or a mirror surface that converges light in the primary scanning direction;
- a plurality of reflective surfaces that reflect light from the lens surface or the mirror surface that converges the light in the primary scanning direction multiple rounds;
- and
- an exit surface that through which light that has been reflected at the plurality of reflective surfaces exits, wherein
- at least one of the plurality of reflective surfaces is formed at the apex of a protrusion and the light that exits from the exit surface is imaged at an image point.
A method of directing light from an original image to an image plane, comprising:
- providing a plurality of reflective surfaces, wherein at least one reflective surface disposed between the original image and image plane is formed having a side wall extending therefrom in the direction of light incident thereon;
- and
- reflecting stray light at the sidewall and directing the light to a location other than the image plane.
