Abstract
A sheet feed mechanism feeds stimulable phosphor sheets, one by one, from a magazine to an image reading unit in an image reading apparatus. The sheet feed mechanism includes a suction mechanism having a plurality of suction cups for attracting a stimulable phosphor sheet in the magazine. The suction mechanism is movable toward and away from the magazine which stores a stack of stimulable phosphor sheets. A grip roller pair grips and guides a stimulable phosphor sheet, which has been taken out of the magazine by the suction cups, in a predetermined direction. One of the suction cups is supported on an angle which is angularly movable in response to engagement of the stimulable phosphor sheet attracted by the suction cups with the grip roller pair. Another angle, when engaged by the grip roller pair, guides a stimulable phosphor sheet, which has undesirably taken out of the magazine, back into the magazine. The sheet feed mechanism has a sheet identifying mechanism operatively coupled to the suction mechanism, for identifying the sheets from the magazine. The identifying means is movable with the suction mechanism toward the magazine, into a position facing an indicia of identifying…
