An image reading apparatus includes three laser stimulating ray sources, a stage on which two or more kinds of image carriers can selectively be placed, a scanning mechanism for scanning the image carrier with a laser beam emitted from the laser stimulating ray sources, thereby stimulating the image carrier, a light detector for photoelectrically detecting light emitted from the image carrier in response to stimulation by the laser beam and a confocal optical system for leading light emitted from the image carrier to the light detector, the image reading apparatus further including a confocal switching member having pinholes of different diameters and disposed between the confocal optical system and the light detector. The thus constituted image reading apparatus can be used for not only a micro-array image detecting system but also an autoradiographic image detecting system, a chemiluminescent image detecting system, an image detecting system using an electron microscope and a radiographic diffraction image detecting system using a stimulable phosphor sheet and a fluorescent image detecting system.
