Compact radiation image information reading apparatus having erasing capability

摘要

A radiation image information reading apparatus includes a reading unit for reading radiation image information recorded in a stimulable phosphor sheet, and an erasing unit for erasing residual radiation image information remaining in the stimulable phosphor sheet after the radiation image information has been read therefrom by the reading unit. A cassette in which the stimulable phosphor sheet is stored is held in a cassette holder which has a feed roller for taking the stimulable phosphor sheet into and out of the cassette. A first sheet feeder feeds the stimulable phosphor sheet from the cassette holder through the reading unit to the erasing unit, and a second sheet feeder feeds for feeding the stimulable phosphor sheet from the erasing unit to the cassette holder. The first and second sheet feeders are disposed parallel to each other. While recorded radiation image information on one stimulable phosphor sheet in the first sheet feeder is being read in the reading unit, another stimulable phosphor sheet may be fed back to the cassette holder by the second sheet feeder.
