Image reading apparatus

An image reading apparatus 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, comprising:

• a projecting lens for projecting the image;
• a plurality of reflecting members for guiding the image from said projecting lens to said screen and said reading unit, at least one of said reflecting members being rockable so as to effect the switch between the observation state and the read state and to scan the image;
• and
• means for changing an inclination angle of a reading surface of said reading unit in association with the rocking movement of said reflecting member.

An image projecting apparatus capable of being switched between an observation mode in which an image is projected onto a screen, and a read mode in which the image is projected onto an image sensor, comprising:

• a projecting lens;
• a first mirror for receiving light from said projecting lens;
• a second mirror for guiding the light reflected at said first mirror to said screen;
• a third mirror for guiding the light reflected at said first mirror to said image sensor, wherein said projecting lens and said third mirror are disposed on the same side of a path of light reflected by said second mirror while said first mirror is disposed on the other side of the path of light reflected by said second mirror;
• and
• means for moving said first mirror between a first position and a second position so as to effect the switch between the observation mode and the read mode, wherein when said first mirror is positioned at the first position the image is projected on said screen, and when said first mirror is positioned at the second position the image is projected onto said image sensor.
