Lowering restriction parts and a biasing member keep the movable lifting wall engaged without adding components or complicating assembly.
A discharge-tray restriction and integrated tray structure prevent lifting wall detachment while preserving capacity and easy assembly.
Movable first and second holding members align large folded-sheet stacks while retreating from the discharge route.
A control unit links paper discharge tray movement with operation unit rotation for convenient transitions beyond printing times.
Pivoted bars connect inputting and outputting trays, enabling synchronized opening and closing without separate manual actions.
A rigid arm with a flat elastic alignment portion and adjustable width members supports sheet sorting, stacking, and dimensional tolerance.
A control portion uses staged width-member positioning to align sheets precisely while reducing alignment time and conveyance load.
A pressing section counters transport force before feeding, flattening sheets to reduce bulging and improve end alignment.
