Abstract

Abstract A stimulable phosphor is exposed to a radiation passing through an object to have a radiation image stored therein, and then exposed to stimulating rays to read out the radiation image and obtain an electric image signal. The image signal is processed under conditions suitable for the type of image recording and used to reproduce a visible image. The conditions of exposure to the radiation and the image processing conditions are adjusted by a single action of selecting the setting conditions predetermined according to the type of image recording. Also, read-out of an identification code provided on the stimulable phosphor and the exposure of the radiation are started by a single action. Or, the read-out of the identification code is conducted in response to memorizing of information on the object.
