  • Patent number: 10940705
    Abstract: A displacement amount calculation part in a base material processing apparatus calculates the degree of matching between an upstream data section and a downstream data section included in a first and a second detection results, which indicate time-varying changes in the positions of an edge of a base material in the width direction at an upstream and a downstream detection positions. This calculation uses calculation results obtained by sequentially calculating the degrees of matching between sub-data sections in the upstream data section and downstream sub-data sections in the downstream data section. This reduces the amount of computation and enables highly accurate detection of the amount of displacement of the base material in the transport direction on the basis of an identification result of the downstream data section that is highly matched with the upstream data section.

  • Patent number: 10919314
    Abstract: A print medium is conveyed in a first direction and a printing head prints an image on the print medium by using a printable region of the print head that extends in a second direction crossing the first direction. Storing units can feed multiple sorts of print media. Among the multiple sorts of the print media, the print medium to print a check pattern for checking a printing state of the printing head is selected as the print medium to be fed from the corresponding storing unit. The check pattern is printed on the print medium by using a portion of the printable region of the printing head corresponding to a size of the print medium fed from the storing unit.
