Abstract
An auxiliary scanning feed mechanism has a pair of curved feed guides for guiding a stimulable phosphor sheet along a curved feed path, and first and second roller pairs rotatable in synchronism with each other for gripping and feeding the stimulable phosphor sheet along the curved feed path. The first and second roller pairs have respective first and second drive rollers disposed inwardly of respective curved sections of the curved feed guides and respective first and second driven rollers.

A radiation image reading apparatus comprising:
- a cassette loading region for loading therein a radiation image recording sheet with a radiation image recorded thereon;
- a feed mechanism having a U-shaped feed path comprising a front feed path for holding and feeding the radiation image recording sheet which has been removed from said cassette loading region to a reading position, said front feed path having a length which is equal to at least the length of the radiation image recording sheet, and a rear feed path for feeding the radiation image recording sheet which has been fed to said reading position, said rear feed path having a length which is equal to at least the length of the radiation image recording sheet, said feed mechanism feeding said radiation image recording sheet through said U-shaped feed path nearly to a rear end of said rear feed path and then feeding said radiation image recording sheet to said cassette loading region;
- an auxiliary scanning feed mechanism disposed in said reading position for feeding said radiation image recording sheet in an auxiliary scanning direction along a feed path having a curved section;
- an optical system for applying stimulating light to said reading position in said U-shaped feed path;
- and
- a light collecting system for reading the radiation image from said radiation image recording sheet which has been irradiated with the stimulating light.
