ABSTRACT:
A cassette houses therein a sheet-shaped radiation image recording medium such that the sheet-shaped radiation image recording medium is capable of being taken out therefrom. A nonwoven fabric is adhered to an inner surface of a flat plate-like portion of the cassette, which portion stands facing an image recording layer of the sheet-shaped radiation image recording medium. The image recording layer is thus prevented from being scratched by dust occurring from a cushioning material or entering the cassette from the exterior. Operations for feeding the sheet-shaped image recording medium into and out of the cassette are not obstructed due to fluctuations in the coefficient of friction of a cushioning material or due to a high coefficient of friction of the cushioning material.
