Image reading apparatus

An image reading apparatus comprising a first laser stimulating ray source for emitting a laser beam having a wavelength of 633 nm or 635 nm, a second laser stimulating ray source for emitting a laser beam having a wavelength of 470 to 480 nm, a laser beam scanning means for scanning a laser beam, at least one light detecting means for photoelectrically detecting light released from an image carrier carrying an image, and at least one filter means disposed in front of the light detecting means and having a plurality of filters for transmitting light of different wavelengths, wherein the image carrier to be scanned with the laser beam emitted from the first laser stimulating ray source is constituted by a carrier, wherein the image carrier carries an image formed from fluorescent substances, or a stimulable phosphor sheet containing a stimulable phosphor recording an image selected from the group consisting of a radiation image, an autoradiographic image, a radiographic diffraction image and an electron microscope image of an object, and the image carrier to be scanned with the laser beam emitted from the second laser stimulating ray source is constituted by a carrier, wherein the image carrier carries an image formed from fluorescent substances, which further comprises a third laser stimulating ray source for emitting a laser beam having a wavelength of 530 to 540 nm.
