Abstract
A cassette for erasing remnant radiation images on a stimulable phosphor sheet without the necessity of taking out the sheet includes a casing for accommodating the stimulable phosphor sheet and a cover pivotally mounted to the casing so as to be opened or closed. The cassette also includes a light reflecting member for reflecting or diffusing the light introduced from outside the cassette for irradiation on an image recording region of the sheet, or a light transmitting member for transmitting the light introduced from outside the cassette or the light from an inner light source, or a light emitting device mounted at least in register wiht the image recording area of the stimulable phosphor sheet contained in the cassette. An erasure device for a stimulable phosphor sheet employing the cassette is adapted to erase radiation energies stored in the sheet by irradiating the sheet with an erasure light, and includes a housing, a device provided in the housing for opening the cassette placed at a predetermined position within the housing and accommodating the stimulable phosphor sheet to be erased, and a light source device provided in the housing and adapted for irradiating the erasur…
