Abstract
In accordance with an embodiment, a lens mirror array includes a plurality of optical elements integrally connected in a first direction. Each optical element includes an incident side lens surface through which light enters the optical element, a ridge located at an edge of the incident side lens surface, a reflection surface on which light incident on the incident side lens surface is reflected, an exit side lens surface through which light reflected by the reflection surface exits the optical element, and a groove surrounding the reflection surface except for a portion adjacent to the ridge, the portion adjacent to the ridge connecting to an adjacent optical element in the plurality of optical elements.
Claims20
A lens mirror array, comprising:
- a plurality of optical elements arranged adjacent to each other in a longitudinal direction of the lens mirror array, wherein
- each optical element is formed by a plurality of outer surfaces including:
- an incident side lens surface through which light enters the optical element,
- a reflection surface connected to the incident side lens surface and from which light incident on the incident side lens surface is reflected, and
- an exit side lens surface and through which light reflected by the reflection surface exits the optical element, and
- the reflection surfaces of each pair of adjacent optical elements form a groove therebetween.
A scanner comprising:
- an illuminating device configured to illuminate a document on a document table glass;
- a lens mirror array having a plurality of optical elements arranged adjacent to each other in a longitudinal direction of the lens mirror array;
- and
- an image sensor configured to receive reflected light from the document via the lens mirror array and output an image signal, wherein
- each optical element is formed by a plurality of outer surfaces including:
- an incident side lens surface through which light enters the optical element,
- a reflection surface connected to the incident side lens surface and from which light incident on the incident side lens surface is reflected, and
- an exit side lens surface through which light reflected by the reflection surface exits the optical element, and
- the reflection surfaces of each pair of adjacent optical elements form a groove therebetween.
An image forming apparatus comprising:
- a light source configured to emit light based on an image signal;
- a lens mirror array having a plurality of optical elements arranged adjacent to each other in a longitudinal direction of the lens mirror array;
- and
- a photosensitive material configured to receive light from the light source via the lens mirror array, wherein
- each optical element is formed by a plurality of outer surfaces including:
- an incident side lens surface through which light enters the optical element,
- a reflection surface connected to the incident side lens surface and from which light incident on the incident side lens surface is reflected, and
- an exit side lens surface through which light reflected by the reflection surface exits the optical element, and
- the reflection surfaces of each pair of adjacent optical elements form a groove therebetween.
