Claims7
An apparatus capable of duplex printing, the apparatus comprising:
- a sheet feeding unit configured to hold and feed a continuous sheet as a sheet;
- a print unit configured to print on the sheet;
- and
- a reverse unit configured to reverse the sheet, wherein the reverse unit includes:
- a winding rotary member having a cylindrical shape and,
- a skew correcting unit configured to correct skewing of a sheet to be led into the winding rotary member, wherein the skew correcting unit includes a contact unit configured to press at least a side portion of the sheet in a width direction of the sheet, wherein the skew correcting unit causes a loop on a portion of the sheet to be led into the winding rotary member, and presses the side portion in a vicinity of the loop by the contact unit to perform skew correction,
- wherein, in the duplex printing, the sheet, fed from the sheet feeding unit and of which a first surface is printed at the print unit, is wound around the winding rotary member, and subsequently, with the sheet fed out from the reverse unit, printing is performed on a second surface that is a back of the first surface at the print unit.
