Abstract

PURPOSE:To easily adjust the optical axis, focus point, and brightness of the projection lens, by using one projection lens which can project areas to be read, optically split into plural parts upon plural blocks of light receiving elements which are parallel to each other. CONSTITUTION:Reading luminous fluxes from a half part of linear area to be read 1 are reflected by the 1st mirror 2 and the 2nd mirror 4 installed above a projection lens 3, and form a reading image 5 after passing through the projection lens 3 vertically. The linear area to be read extended vertically in the paper reflects a reading luminous flux when it is illuminated with illuminating light sources 6 and 6'. This reading luminous flux is reflected by the 1st mirror 2 installed to a location out of a reading plane including the area to be read and the optical axis of the projection lens 3, and the 2nd mirror 4 installed to the other side of the above mentioned reading plane which is opposite side of the 1st mirror 2, and the luminous flux is obliquely supplied to the projection lens 2. The reading images 5 and 5' are formed at locations which are symmetrical to the reading plane and which are far from the reading plane.
