A sheet processing apparatus and a sheet take-out apparatus that prevents a sheet conveyed by a take-out portion from hanging-down and falling, when the take-out portion is stopped due to an emergency. If a take-out emergency process state occurs during the take-out of sheets, the sheet take-out apparatus stops upward movement of a backup plate, moves down feed stoppers, and presses a sheet bundle from above to prevent the sheet on the uppermost surface from being taken out. The sheet take-out apparatus also keeps a rotor air valve on and takes out the sheet caught in a sheet take-in port. When residual sheets on the backup plate are later detected, the sheet take-out apparatus moves down the position of the backup plate, turns off air valves for the rotor, fixed absorbing unit, and handling, and loads a hanging-down sheet on the backup plate, to prevent the sheet from scattering.

The switchback device has two switchback portions for inverting the conveying path of paper-like materials and a detour conveying path. The switchback portions receive paper-like materials in the nip between the switchback rollers and the pinch rollers, clamp the paper-like materials, decelerate, stop, and accelerate them in the opposite direction in a clamping state, thereby switch back the paper-like materials. The stopping time of paper-like materials in the switchback portions is changed according to the length of the paper-like materials in the conveying direction.
