Reflection type optical sensor and image generation apparatus

摘要

A reflection type optical sensor that detect a surface condition of a moving body and that is used for an image generation apparatus which forms images on a recording media includes a light-emitting device which has a plurality of light emitter systems including at least two light-emitting members and a light-emitting optical system having a plurality of light-emitting lenses corresponding to a plurality of the light emitter systems and guiding light emitted from the light emitter systems to the moving body and a light-receiving device which has a light receiver system including at least two light-receiving members and a light-receiving optical system having light-receiving lenses corresponding to the at least two light-receiving members and guiding light reflected by the moving body to the light receiver system. The image generation apparatus has further a surface condition judging device in addition to the reflection type optical sensor.

主权项

1. A reflection type optical sensor for detecting a surface condition of a moving body, comprising:
a light-emitting device having
a plurality of light emitter systems including at least two light-emitting members, anda light-emitting optical system including a plurality of light-emitting lenses corresponding to the plurality of light emitter systems and configured to guide light emitted from the plurality of light emitter systems to the moving body; and a light-receiving device having
a light receiver system including at least two light-receiving members, anda light-receiving optical system having a plurality of light-receiving lenses corresponding to the at least two light-receiving members and configured to guide light reflected by the moving body to the light receiver system, wherein the plurality of light emitter systems are arranged in a direction such that optical axes of light-emitting lenses corresponding to each of the plurality of light emitter systems are between two arbitrary light-receiving members of the at least two light-receiving members.
