Claims

[Scope of utility model registration request]

A facsimile machine is equipped with a reflective optical coupling element consisting of a light emitting element and a light receiving element, and a medium having a plurality of reflective surfaces with different reflectances corresponding to the width of each document, and a document is placed on a document table and a document guide is used. The reflective optical coupling element and the medium are arranged so that when aligned with the edge of the original, the light from the light emitting element is reflected only by the reflecting surface corresponding to the width of the original and enters the light receiving element. A document width detection mechanism disposed on the document table and the document guide.
