Scanner, reading system, and computer program that sequentially supplies image data to an external device

A non-transitory computer readable recording medium storing a computer program for causing a scanner which has, a reading section configured to read an image recorded on a sheet so as to generate image data, and which is connected to an external device through a network, and which is configured to operate in a first operation mode and a second operation mode, to perform processing, the computer program causes the scanner to perform:

• if the first operation mode is selected,
• sequentially generating, in a case where a plurality of images recorded on a plurality of sheets are read by the reading section, an image data group every time n (n>=1) number of sheet among the plurality of sheets is read by the reading section, and sequentially supplying the generated image data group to the external device, each image data group including n number of image data corresponding to the n number of sheet, and n number of sheet being a part of the plurality of sheets;
• and
• generating joint information used to join two or more of the image data groups, the two or more of the image data groups representing the plurality of images;
• supplying the joint information to the external device, and
• if the second operation mode is selected,
• joining the plurality of image data corresponding to the plurality of sheets after reading the plurality of sheets, so as to generate a joined file, in a case where a plurality of images recorded on a plurality of sheets are read by the reading section;
• and
• supplying the joined file to the external device.

A method for controlling a scanner which has, a reading section configured to read an image recorded on a sheet so as to generate image data, which is configured to be connected to an external device through a network, and which is configured to operate in a first operation mode and a second operation mode, the method comprising;

• if the first operation mode is selected,
• sequentially generating, in a case where a plurality of images recorded on a plurality of sheets are read by the reading section, an image data group every time n (n>=1) number of sheet among the plurality of sheets is read by the reading section, and sequentially supplying the generated image data group to the external device, each image data group including n number of image data corresponding to the n number of sheet, and n number of sheet being a part of the plurality of sheets;
• generating joint information used to join two or more of the image data groups, the two or more of the image data groups representing the plurality of images;
• and
• supplying the joint information to the external device, and
• if the second operation mode is selected,
• joining the plurality of image data corresponding to the plurality of sheets after reading the plurality of sheets, so as to generate a joined file, in a case where a plurality of images recorded on a plurality of sheets are read by the reading section;
• and
• supplying the joined file to the external device.
