Overhead projector printer

Abstract

Abstract PURPOSE:To obtain a small-sized and portable overhead projector capable of photographing and printing by sliding a line sensor to receive the light on a screen which is irradiated in a bright line from an illuminating device through a photographic device and photographing an image. CONSTITUTION:In the projection mode, an original picture is placed on a Fresnel condenser mirror 40 and is projected onto a screen like a white plate through a projection lens 21. In the photographic mode, a linear condenser lens 33 is placed on the optical axis, and the light discharged from the lens 33 is converged into a bright line. In this state, a line sensor 12 is slid to receive the light from the screen which is made incident through a photographic lens 11, and it is photographed. In the mixture mode, the original picture on the mirror 40 is projected on the screen by the projcetion mode, and another desired original picture is written over said projected picture, and the mode is switched to the photographic mode to photograph them. In the copy mode, an original picture written on an ordinary paper is placed on the mirror 40, and the optical axis of an image pickup system is set vertically, and the original picture is photographed directly.
