Abstract: A radiation image information recording and reading system includes a circulatory feed system for feeding a stimulable phosphor sheet, an image recording device for recording radiation image information in the stimulable phosphor sheet, an image reading device for reading the recorded radiation image information from the stimulable phosphor sheet, and a remaining image erasing device for discharging radiation energy remaining on the stimulable phosphor sheet before the stimulable phosphor sheet is readied for another recording cycle. If a power supply supply turn-off command signal is produced in error to turn off the power supply of the system, a control device energizes a breaker circuit to break the power supply circuit a predetermined period of time after the power supply turn-off command signal is produced.

Abstract: A radiation image information recording and reading system includes a circulatory feed system for feeding a stimulable phosphor sheet, an image recording device for recording radiation image information in the stimulable phosphor sheet, an image reading device for reading the recorded radiation image information from the stimulable phosphor sheet, and a remaining image erasing device for discharging radiation energy remaining on the stimulable phosphor sheet before the stimulable phosphor sheet is readied for another recording cycle. Stimulable phosphor sheets loaded in the system are detected by sheet sensors, so that the number and positions of stimulable phosphor sheets in the system can be confirmed. Whether there is a predetermined number of stimulable phosphor sheets in the system can also be confirmed based on the information with regard to the number and positions of the stimulable phosphor sheets.
