Data processor and scanner device

A data processor comprising:

• a control unit configured to execute instructions instructing the control unit to provide functional units including:
• an image acquiring unit that is configured to acquire a plurality of sets of image data indicating a plurality of images;
• a reference file acquiring unit that is configured to acquire a reference file including a single reference object including first information indicating a layout of at least two images among the plurality of images;
• and
• a file generating unit that is configured to generate a file including at least one subfile in which at least one image of the plurality of images is laid out based on the first information included in the single reference object,
• wherein, when the file generating unit generates the file, the file generating unit is configured to determine a positional relation between any adjacent two of the plurality of images using the first information included in the single reference object,
• wherein a format of the file is the same as a format of the reference file,
• wherein the first information includes first maximum number information indicating a first maximum number, the first maximum number being a maximum number of images that can be arranged in the subfile,
• wherein the reference file includes a first plurality of cells arranged in a grid with vertical columns and horizontal rows, wherein a part of the first plurality of cells is classified into a first cell group, the first cell group defining a first region in which the reference object is arranged,
• wherein the file generating unit generates the subfile of the file including a second plurality of cells arranged in a grid with vertical columns and horizontal rows, a part of the second plurality of cells in the subfile being classified into a plurality of second cell groups, each of the plurality of second cell groups defining a second region whose size is equivalent to a size of the first region, each of the plurality of images being laid out in one of the plurality of second cell groups,
• wherein the reference file includes a reference space between an outline of the first region and an outline of the reference object in a prescribed direction,
• wherein, when the file generating unit generates the subfile of the file, the file generating unit repeatedly arranges one image of the plurality of images adjacent to a previously arranged image such that a second cell group for the one image abuts a second cell group for the previously arranged image and such that a space between an outline of the one image and an outline of a second region of the second cell groups for the one image in the prescribed direction matches the reference space, the file generating unit arranging the one image and the previously arranged image in the prescribed direction,
• wherein, when a number of the plurality of images acquired by the image acquiring unit is less than or equal to the first maximum number, the file generating unit generates the file including only one subfile in which all of the plurality of images are laid out, and
• wherein, when a number of the plurality of images which is acquired by the image acquiring unit is greater than the first maximum number, the file generating unit generates the file including a first subfile in which the first maximum number of images among the plurality of images are laid out and a second subfile in which at least one image among the plurality of images that is excluded from the first maximum number of images laid out in the first subfile is laid out.
