Abstract
An image reading device includes a single light source that irradiates an image reading target with light, a traveling change member that changes a traveling direction of the light from the light source and irradiates the image reading target with the light at an incidence angle different from an incidence angle of the light directly applied from the light source to the image reading target, and a switching mechanism that switches traveling of the light from the light source to an optical path for directly irradiating the image reading target or an optical path for irradiating the image reading target via the traveling change member.
Claims20
An image reading device comprising:
- a single light source that irradiates an image reading target with light;
- a traveling change member that changes a traveling direction of the light from the light source and irradiates the image reading target with the light at an incidence angle different from an incidence angle of the light directly applied from the light source to the image reading target;
- and
- a switching mechanism that switches traveling of the light from the light source to an optical path for directly irradiating the image reading target or an optical path for irradiating the image reading target via the traveling change member.
A non-transitory computer readable medium storing an image reading program causing a computer to execute a process of:
- irradiating an image reading target with light from a single light source;
- changing a traveling direction of the light from the light source via a traveling change member and irradiating the image reading target with the light at an incidence angle different from an incidence angle of the light directly applied from the light source to the image reading target;
- and
- switching traveling of the light from the light source to an optical path for directly irradiating the image reading target or an optical path for irradiating the image reading target via the traveling change member.
An image reading method comprising:
- irradiating an image reading target with light from a single light source;
- changing a traveling direction of the light from the light source via a traveling change member and irradiating the image reading target with the light at an incidence angle different from an incidence angle of the light directly applied from the light source to the image reading target;
- and
- switching traveling of the light from the light source to an optical path for directly irradiating the image reading target or an optical path for irradiating the image reading target via the traveling change member.
