摘要： A base material processing apparatus includes first and second edge sensors and a displacement amount calculation part. The first edge sensor acquires a first detection result (R1) by detecting the position of an edge of a base material in a width direction at a first detection position. The second edge sensor acquires a second detection result (R2) by detecting the position of the edge of the base material at a second detection position. The displacement amount calculation part calculates the amount of displacement in the position of the base material in the transport direction or the amount of difference in the transporting speed of the base material on the basis of the first and second detection results (R1, R2). Thus, the amount of displacement in the position or the amount of difference in the transporting speed can be detected without depending on images such as register marks.

摘要： In printing apparatus, an edge sensor detects a serpentine amount caused by transportation of a web. A predicted waveform data generating unit generates predicted waveform data on the serpentine amount to be produced in the following web in accordance with actually measured waveform data on the detected serpentine amount. A correcting unit corrects a printing position of an image in accordance with a shift amount, and applies a corrected printing position to a printing head. Here, the shift amount is determined with the shift amount determining unit in accordance with the predicted waveform data. Accordingly, the shift amount is determinable in accordance with the actually measured waveform data on the serpentine amount detected with the edge sensor more accurately than that through a method in which a shift amount is directly determined. This allows suppressed misregister.

摘要： A base material processing apparatus includes a first detector, a second detector, and an arithmetic unit. The first detector intermittently detects the position of the edge of the base material in the width direction at a first detection position to acquire a first detection result (Ra). The second detector intermittently detects the position of the edge of the base material in the width direction at a second detection position located downstream of the first detection position to acquire a second detection result (Rb). The arithmetic unit calculates a transport error of the base material by comparison between the first detection result (Ra) and the second detection result (Rb). The controller changes detection timing of at least one of the first detector and the second detector.

摘要： A transport apparatus includes a correction mechanism, a detector, and a meandering attenuator. The detector detects a widthwise position of elongated strip-shaped printing paper. The correction mechanism corrects the widthwise position of the printing paper, based on a detection result from the detector. The meandering attenuator is disposed upstream or downstream of the correction mechanism as seen in a transport direction. The meandering attenuator includes a plurality of attenuation rollers rotating while being in contact with the printing paper. When the printing paper passes over the attenuation rollers, the meandering of the printing paper is attenuated by the friction between the attenuation rollers and the printing paper. Thus, meandering exceeding the correction capability of the correction mechanism and new meandering occurring in the correction mechanism are attenuated.

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.
