摘要： An image signal is read out by use of a stimulable phosphor sheet having a layer of stimulable phosphor which emits stimulated emission in proportion to the stored energy of radiation upon exposure to stimulating light and a solid image sensor having a photoconductive material layer which exhibits electric conductivity upon exposure to the stimulated emission from the stimulable phosphor sheet. Stimulating light is caused to scan a stimulable phosphor sheet which has been exposed to radiation and has stored an image, the photoconductive material layer is caused to be exposed to stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light. Then electric charges generated in the photoconductive material layer upon exposure to the stimulated emission is detected by applying an electric field to the photoconductive material layer. The stimulable phosphor sheet has a layer of stimulable phosphor which is stimulated by stimulating light in a wavelength range of not shorter than 600 nm and emits stimulated emission in a wavelength range of not longer than 500 nm. The solid image sensor has a photoconductive material layer whose major component is a-Se, and the electric field is such as to generate an avalanche amplification effect in the photoconductive material layer.

摘要： An image recording medium for recording image information by storing electric charges generated in response to exposure to an electromagnetic wave carrying the image information. The image recording medium includes: an electrode transparent to the electromagnetic wave; a recording-side photoconductive layer which contains a-Se as a main component, and generates electric charges when exposed to the electromagnetic wave; and a suppression layer which is arranged between the electrode and the recording-side photoconductive layer, and suppresses interfacial crystallization in the recording-side photoconductive layer. The suppression layer is made of an organic material which behaves as an insulator against electric charges having the opposite polarity to electric charges which move from the recording-side photoconductive layer to the electrode at the time of recording, and as a conductor of charges having the same polarity as the electric charges which move to the electrode.

摘要： An image recording medium includes a support body which allows reading electromagnetic waves to pass through it, a first electrode layer which allows the reading electromagnetic waves to pass through it, a photoconductive reading layer which exhibits conductivity when irradiated with the reading electromagnetic waves, a charge storage portion for storing a latent-image polarity charge, a photoconductive recording layer for generating the latent-image polarity charge when irradiated with recording electromagnetic waves, and a second electrode layer which allows the recording electromagnetic waves to pass through it. The difference in thermal expansion coefficient between the support body and the photoconductive reading layer is small so that no structural destruction occurs between the support body and the photoconductive reading layer because of thermal stress generated by a temperature change in environment.

摘要： A read-out apparatus for an image detector scans the image detector, on which image information has been recorded as an electrostatic latent image, with a reading electromagnetic wave and detects electric currents caused by the scanning to flow out of the image detector in accordance with the electrostatic latent image. The read-out apparatus comprises a surface-shaped wave source constituted of a plurality of small wave sources, which are arrayed in a surface form and each of which produces the reading electromagnetic wave, and a wave source controller for performing the scanning by driving the small wave sources one after another. The read-out apparatus reads out the electrostatic latent image without mechanical scanning being required.
