Abstract
An image reading device includes plural light sources that irradiate an image reading target with light at different angles; and a switching mechanism that sequentially switches the light incident to the image reading target from the plural light sources during an image reading operation on the image reading target.
Claims16
An image reading device comprising:
- a plurality of light sources, comprising a first light source and a second light source, that irradiate an image reading target with light at different angles;
- and
- a switching mechanism that sequentially switches the light incident to the image reading target from the plurality of light sources during an image reading operation on the image reading target,
- wherein a turning-on time of the second light source is set to be shorter than a turning-on time of the first light source.

A non-transitory computer readable medium storing an image reading program causing a computer to execute:
- irradiating an image reading target with light at different angles;
- and
- sequentially switching the light incident to the image reading target from a plurality of light sources during an image reading operation on the image reading target,
- wherein the plurality of light sources comprise a first light source and a second light source, and
- wherein a turning-on time of the second light source is set to be shorter than a turning-on time of the first light source.
