ABSTRACT:
An improved image pick-up apparatus for use in a facsimile equipment, phototelegraphic apparatus or the like is disclosed which enables these equipment and apparatus to have a reduced height with the aid of light beam passage changing devices such as mirrors. In this apparatus light beam is first emitted to the surface of an original manuscript from a light source and then the light beam after being reflected on the surface of the manuscript advances to photoelectric converting elements of an elongated photo sensor by way of the light beam passage changing device which serves to direct the light beam reflected on the surface of the manuscript to the photoelectric converting elements in such a manner that the optical axis of an optical system such as a light beam condensing optical fiber for building an image on the latter is directed substantially in parallel with the surface of the original manuscript.
