1. A light detector unit for use in an information reading device for reading flexible information carriers which are bent into at least partly cylindrical geometry by positioning on an information carrier support that is at least partially cylindrical, comprising a light detector arranged on an axis of the information carrier support, the light detector having an entrance window and a radius that essentially corresponds to a radius of the at least partially cylindrical surface of the information carrier support.
