ABSTRACT:
An image readout apparatus applies stimulating light emitted from a laser beam source to a stimulable phosphor sheet which stored a radiation image of an object such as a human body to be diagnosed and reads out a radiation image based on light emitted from the stimulable phoshpor sheet upon exposure to the stimulating light. The image readout apparatus includes an image readout mechanism and a casing accommodating the image readout mechanism. Vibro-isolating light shield members are interposed between the image readout mechanism and the casing, which are individually supported on a floor. Vibro-isolating members are also disposed between a conveyor mechanism for delivering the stimulable phosphor sheet and an optical system for applying the stimulating light to the stimulable phosphor sheet. Shocks imposed inadvertently by the operator or the person being diagnosed on the casing, or vibration induced by the conveyor mechanism in operation, is attenuated to a considerable extent while being transmitted to the optical system. Therefore, the optical axis of the stimulating light is prevented from being disturbed with respect to the stimulable sheet, so that the radiation image can be produced highly accurately.
