Sheet feeding apparatus having means for determining the leading edge of a sheet

摘要

A sheet feeding apparatus includes a guiding path for guiding a sheet, a detector for detecting the presence/absence of the sheet in the guiding path, a power-supply switch for turning on and off a power supply, and a determination device for determining whether the sheet comprises a rolled sheet or a cut sheet according to whether the detector detects or does not detect the sheet, respectively, when the power-supply switch has been turned on.
