1. A sheet processing apparatus comprising:
a support on which a sheet is supported;
a conveyor configured to convey the sheet toward the support in a first direction in which a first end of the sheet is a leading end of the sheet;
a rotary guide provided above the support and including a first guide surface configured to guide a lower surface of the sheet conveyed by the conveyor and a second guide surface that is configured to face the support in a state in which the rotary guide is in a predetermined position, wherein in a case where the rotary guide is rotated in a state in which a second end of the sheet opposite to the first end is located above the first guide surface, the rotary guide is configured to move the second end of the sheet from above the first guide surface to a space that is formed between the second guide surface and the support in a state in which the rotary guide is in the predetermined position;
a processor configured to process the sheet supported on the support;
a discharger configured to discharge the sheet processed by the processor; and
a moving assembly configured to move the sheet in a second direction in which the second end of the sheet becomes a leading end of the sheet, such that the sheet processed by the processor is moved from the support toward the discharger through the space between the second guide surface and the support;
wherein in a state where the rotary guide is in the predetermined position and before the moving assembly starts moving the sheet in the second direction, the second guide surface extends from a position upstream of the second end of the sheet in the second direction to a position downstream of the second end of the sheet in the second direction.
