Abstract
An improved cut sheet feeder for feeding cut sheets separately one by one, comprising a sheet feeding and conveying device for contacting the obverse side of a first sheet to move the first sheet forwardly by frictional force, an arresting device for contacting the reverse side of a next sheet to arrest forward movement of the next sheet, the frictional force applied by the sheet feeding and conveying device being larger than the frictional force applied by the arresting device. The improved cut sheet feeder comprises a suction device operatively associated with the sheet feeding and conveying device for sucking the first sheet to increase the frictional force between the first sheet and the sheet feeding and conveying device. In a modified embodiment, a suction device may be operatively associated with the arresting device rather than being operatively associated with the sheet feeding and conveying device. In a further modified embodiment, a suction device may be operatively associated with the arresting device in addition to the suction device operatively associated with the sheet feeding and conveying device.
