Abstract:
A sheet feeding device capable of improving user's convenience even in a case where non-long sheets and long sheets are switchingly used. A sheet storage opened and closed for storing sheets to be used for image formation. A deck supply path feeds sheets from the sheet storage. A first and a second lift plate are provided in the sheet storage, side by side, in a sheet feeding direction. The first and second lift plates can be lifted up and down by a lift mechanism. A CPU determines whether or not an operation concerning storing long sheets in the sheet storage has been performed. When it is determined that the operation has been performed, the CPU controls the lift mechanism to cause the levels of the first and second lift plates to match each other.

Claim (Index 11):
An image forming system including:\n a sheet feeding device, and an image forming apparatus that forms images on sheets fed from the sheet feeding device, wherein the sheet feeding device comprises: a storage configured to be openable and closable, and to store sheets to be used for image formation; a feed unit configured to feed sheets from the storage; a first lift plate and a second lift plate, provided in the storage, side by side, in a sheet feeding direction, and each configured to be capable of being lifted up and down; a lifter configured to lift up and down the first lift plate and the second lift plate; and a controller configured to determine whether or not an operation has been performed concerning storing of long sheets longer than a predetermined length in the sheet feeding direction, in the storage, and to control the lifter, in a case where it is determined that the operation has been performed, to cause a level of the first lift plate in a height direction and a level of the second lift plate in the height direction to match each other.
