摘要： An image reading device includes: a conveying unit for conveying an irradiated member that has a hologram area in a conveying direction; a first light source for applying light to an irradiated part in the hologram area; and a second light source separated from the first light source along the conveying direction and applying light to an irradiated part in the hologram area when the hologram area is conveyed by a prescribed distance. An irradiation angle at which the irradiated part is irradiated with the light of the first light source is made to be different from an irradiation angle at which the irradiated part is irradiated with the light of the second light source when the hologram part is conveyed by the prescribed distance. Lights reflected by the hologram area are respectively received to detect an electric signal of the hologram area of the irradiated member.

摘要： An image sensor includes: a light source that irradiates a light on an object; a lens body that converges a reflection of the light from the object; a plurality of IC chips that receive the reflection passed through the lens body; and a transparent member provided between the IC chips and the lens body. The transparent member includes a refractive index changing region provided at a portion opposite to a gap between adjacent IC chips. A refractive index in the refractive index changing region increases continuously or stepwise toward an inner portion of the transparent member from a surface of the transparent member on an IC chips side so that the refractive index changing region refracts a part of the reflection to be incident into the gap to the IC chips.
