Abstract

An image reading device having 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.
