Sheet feeder, e.g. for copier or scanner, has image reader and generator, turns rollers in forward direction after turning them in reverse direction by certain amount after sheet insertion

摘要

The arrangement has a pair of rollers (3,4) for feeding a sheet (P) that runs up to a clamp section of the roller pair, a drive arrangement (14,19) that turns the roller pair forwards or backwards, a sheet acquisition device and a controller that controls the roller pair to turn them in the forward direction, after turning them in the reverse direction by a certain amount when the sheet is inserted into the clamp section. Independent claims are also included for an image generator arrangement and an image reader arrangement.
