ABSTRACT:
An image reading apparatus is capable of being switched between an observation state in which an image on a recording medium is projected onto a screen and observed and a read state in which the image is projected onto a reading unit and read. The apparatus includes a projecting lens provided in a lower portion of the apparatus to project the image, a rockable first reflecting member provided in an upper portion of the apparatus to reflect the image light from the projecting lens and, a second reflecting member provided in opposition to the screen to guide the image light reflected by the first reflecting member to the screen. A third reflecting member is provided below the second reflecting member to guide the image light reflected by the first reflecting member to the reading unit. The observation state and the read state are switched by the rocking motion of the first reflecting member.
