ABSTRACT:
A device for reading in a reduced scale a relatively wide document, e.g., a display board of a graphic input device by projecting an image of the document onto a photoelectric transducer through an image-forming lens. A pair of flat mirrors are provided which consist of a first and a second mirror that are located to face and substantially parallel to each other. A beam is reflected a plurality of times between the mirrors to be propagated toward the lens. Each of the flat mirrors is supported at both of its ends and with its reflective surface oriented substantially vertically. One of the first and second mirrors is inclined relative to the other so that their distance sequentially increases toward the lens. A transparent base plate is provided which has a document transport surface for illuminating the document in a slit configuration. A reflective film is provided on a part of the opposite surface of the base plate to the document transport surface, serving as one of the first and second mirrors.
