Abstract
A sheet conveyance apparatus for winding a sheet around a rotator, pulling the sheet wound around the rotator, and sending out the sheet includes a guiding unit that guides a sheet side end pulled from the rotator. The guiding unit forms a slack in the outer periphery of the sheet wound around the rotator, and guides the side end of the sheet sent from the rotator.
Claims16
A printing apparatus for winding a sheet printed on a surface of the sheet around a rotary member, sending out the sheet wound around the rotary member, and performing printing on a surface of the sheet in a printing unit, the printing apparatus comprising:
- a conveying unit configured to convey the sheet to the rotary member;
- and
- a regulating unit configured to regulate a position of a side end of the sheet pulled from the rotary member,
- wherein the conveying unit and the rotary member are driven so that the sheet conveyed by the conveying unit is wound around the rotary member and a slack is formed in an outer periphery of the sheet wound around the rotary member, and
- wherein the regulating unit regulates the position of the side end of the sheet pulled from the rotary member in a state where the slack is formed around the rotary member.
A sheet handling apparatus for winding a sheet around a rotary member, and sending out the sheet wound around the rotary member, the sheet handling apparatus comprising:
- a conveying unit configured to convey the sheet to the rotary member;
- and
- a regulating unit configured to regulate a position of a side end of the sheet sent out from the rotary member,
- wherein the conveying unit and the rotary member are driven so that the sheet conveyed by the conveying unit is wound around the rotary member and a slack is formed in an outer periphery of the sheet wound around the rotary member, and
- wherein the sheet is sent out in a state where the slack is formed in the outer periphery of the sheet wound around the rotary member, and the regulating unit guides the sheet side end sent out from the rotary member.
A printing apparatus for winding a sheet printed on a surface of the sheet around a rotary member, pulling the sheet from the rotary member, conveying the sheet to a printing position where printing is performed, and performing printing on a surface of the sheet at the printing position by a printing unit, the printing apparatus comprising
- a conveying unit configured to convey the sheet to wind the sheet around the rotary member and pull the sheet from the rotary member;
- a rotating unit configured to rotate the rotary member to wind the sheet around the rotary member and pull the sheet from the rotary member:
- and
- a regulating unit configured to regulate a position of a side end of the sheet pulled from the rotary member,
- wherein the conveying unit conveys the sheet in a state where the rotary member stops for winding the sheet around the rotary member and wherein the regulating unit regulates the position of the side end of the sheet pulled from the rotary member by causing the conveying unit to convey the sheet and the rotating unit to send out the sheet at substantially same speed.
