APPARATUS FOR AND METHOD OF RECORDING IMAGE

摘要

In an image recording apparatus, edge sensors are disposed in front of and behind a recording position on a transport path of printing paper. The edge sensors detect a widthwise position of the printing paper in respective positions upstream and downstream of the recording position. A controller in the image recording apparatus calculates the widthwise position of the printing paper in the recording position, based on detection results from the edge sensors. Thus, the widthwise position of the printing paper in the recording position is identified without the placement of an edge sensor in the recording position on the transport path.

主权项

1. An image recording apparatus comprising:
a transport mechanism for transporting an elongated strip-shaped recording medium in a longitudinal direction thereof along a predetermined transport path; at least one recording head for recording an image on a surface of the recording medium in a recording position on said transport path; an upstream detector for detecting a widthwise position of the recording medium in a position upstream of said recording position on said transport path; a downstream detector for detecting the widthwise position of the recording medium in a position downstream of said recording position on said transport path; and a calculation part for calculating the widthwise position of the recording medium in said recording position, based on detection results from said upstream detector and said downstream detector.
