Claims

[Scope of utility model registration request]

An optical fiber array plate in which a large number of optical fibers are closely fixed and formed into a plate shape is used as a light guiding member, and a document is closely and slidably placed on one of the front end surfaces of the fiber array plate. At the same time,
A contact type original reading device, characterized in that a contact type image sensor for reading is closely arranged on the other end face, and a light source for irradiating the original is installed on at least one side of the fiber plate.
