Abstract
In a sheet feeding device having a forwardly rotating conveying rotary member and a reversely rotating separating rotary member, and for separating and conveying sheets one by one by a sheet separating portion comprised of these two rotary members, the setting of an appropriate center distance when a sheet is separated and conveyed with the center distance between the conveying rotary member and the separating rotary member fixed is effected smoothly within a short time, and a first sheet feeding mode for effecting sheet feeding while automatically adjusting the center distance for each sheet by a center distance changing device and a controller and a second sheet feeding mode for effecting sheet feeding with the center distance fixed can be arbitrarily selected, and when the setting of the center distance during the selection of the second sheet feeding mode is to be effected, the execution of the center distance setting standard operation (adjusting operation) of detecting the center distance automatically adjusted when one or any plurality of sheets are fed in the first sheet feeding mode, and displaying the set value of the center distance based on the result of the detection o…
