Patent attributes
A printer-processor is provided with a paper feed path that is constituted of a plural number of pairs of conveyer rollers, and a feedback path that branches off the paper feed path to feed a sheet of recording paper back to an upstream position of the paper feed path that is placed before an image recording section. For both-side printing, the paper sheet is first conveyed in a forward direction through the image recording section, to record an image on one side. After being conveyed further in the forward direction along the paper feed path to go past a branching section to the feedback path, the paper sheet is conveyed backward into the feedback path. Thus, the conveying direction through the image recording section is unchanged regardless of which side of the paper sheet is served for the image recording. While the paper sheet is being switched back at the branching section, another paper sheet may be fed into the paper feed path for recording another image thereon through the single image recording section.
