摘要：The present invention provides an optical information reading device includes: alight source that irradiates, with reference beam, a hologram recorded in an optical

recording medium; a reading unit that reads information from a holographic imagereconstructed by the reference beam being diffracted by the hologram; a housing; acontact member of the housing contacting a paper; an open portion formed in thecontact member, through which the optical recording medium is exposed and towardswhich the reference beam is emitted; an alignment mark formed at a periphery of theopen portion, the reference beam irradiating the hologram satisfying a holographicimage reconstruction condition by the alignment mark being aligned with an opticalrecording medium alignment mark recorded on the optical recording medium; and aviewing portion that is positioned in the housing and through which the alignment markand the optical recording medium alignment mark are visible.
