Abstract:
1. A sheet-supply device for supplying sheets from a stack of sheets one at a time in a guide direction, the sheet-supply device comprising: a sheet supporting member with a sheet-supporting surface that supports the stack of sheets; a sheet feed unit applying a force to a sheet in the stack to move the sheet in a sheet feed direction; a guide member disposed at a downstream side of the sheet supporting member with respect to the sheet feed direction, the guide member having a guide surface that guides the sheet in the guide direction as the sheet slides across the guide surface, the guide surface generating a resistance to sliding movement of sheets; a stopper member disposed in the guide member and having a stack-slippage prevention surface capable of imparting a larger resistance to sliding movement of sheets than the guide surface, the stopper member being movable between: a stopper moving mechanism that selectively moves the stopper member between the protruding position and the retracted position.
