Abstract
A sheet feeding apparatus is disclosed that includes a plurality of size sensors configured to be arranged in line and to detect a sheet set into a predetermined position; a feeding part configured to feed the sheet set into the predetermined position to a scan position; and a controller configured to control the feeding part to feed the sheet based on two detect signals output from two size sensors among the plurality of the size sensors.
Claims18
A sheet feeding apparatus comprising:
- a plurality of size sensors arranged in a same direction and configured to detect a sheet set at a first position;
- a feeder configured to feed the sheet set at the first position to a scan position;
- and
- a controller configured to control the feeder to feed the sheet based on two detect signals output from two size sensors, respectively, among the plurality of the size sensors, the plurality of size sensors configured to detect a plurality of different sheet widths and the two size sensors configured to detect one width corresponding to the sheet of the plurality of different sheet widths.

- a feeder configured to feed the sheet at the first position to a scan position;
- and
- a controller configured to control the feeder to feed the sheet based on two detect signals output from two size sensors, respectively, among the plurality of the size sensors, wherein the controller determines a size of the sheet based on the detect signal output from at least one of the two size sensors before controlling the feeding part to feed the sheet, and wherein the plurality of the size sensors are arranged in pairs, each pair of the size sensors configured to detect respective edges corresponding to a different size of the sheet.
