  • Publication number: 20200406639
    Abstract: A base material processing apparatus includes a transport mechanism, a mark detector, and a calculating unit. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a predetermined transport path. The mark detector acquires a detection result by detecting a mark continuously at a detecting position on the transport path. The mark is applied previously to an end of the base material in a width direction thereof. The calculating unit calculates a transport speed of the base material, the amount of positional deviation of the base material in a transport direction, and tension on the base material applied in the transport direction on the basis of the detection result and information about the mark applied previously to the base material.

  • Patent number: 10479116
    Abstract: 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.

  • Publication number: 20160288543
    Abstract: 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.

  • Patent number: 5038383
    Abstract: Cutout mask data is easily obtained while setting small unit areas in an original image and displaying them in order on a display unit. Unit areas including vertexes of an outline of a cutout mask are first designated. Unit area images within the unit areas are simultaneously displayed on a display unit. An operator sequentially designates positions of the vertexes while watching the unit area images arrayed in order of the designation. Cutout mask data are formed on the basis of the positions of the vertexes.
