Scanner and non-transitory computer-readable recording medium for image processing device

A non-transitory computer-readable recoding medium containing instructions to be executed by a controller of an image processing device, the image processing device is connected to a scanner which is provided with a conveying part, an image sensor, a detection sensor, the conveying part being configured to sequentially convey multiple original sheets along a conveying passage, the image sensor being arranged on the conveying passage and configured to optically read the original sheet being conveyed along the conveying passage, the detection sensor being configured to detect physical information regarding the original sheet being conveyed, the scanner being configured to output read image data based on an output signal of the image sensor,

• the instructions cause, when executed by the controller, the image processing device to perform:
• obtaining particular image information regarding a particular image, the particular image being an image indicated on a particular fixed object which is fixed to the original sheet in an overlapped state;
• receiving sensor information based on an output signal of the detection sensor, the sensor information indicating whether or not a detection position of the detection sensor of the original sheet being conveyed is an overlapped position which overlaps with another object;
• receiving target image data containing at least a partial image of the original sheet at a detection area including the detection position, the target image data being received from the scanner;
• determining whether the particular fixed object including the particular image exists at the detection area of the original sheet by analyzing the target image data with use of the particular image information;
• transmitting interruption command to the scanner when the sensor information indicates that the detection position is the overlapped position and when it is determined that a particular fixed object does not exists at the detection area;
• and
• generating original sheet image data representing an image of the original sheet with use of the target image data received from the scanner.

A scanner, comprising:

• a conveyer configured to sequentially convey a plurality of original sheets along a conveying passage;
• an image sensor arranged on the conveying passage and configured to optically read the original sheet being conveyed along the conveying passage;
• a detection sensor configured to detect physical information regarding the original sheet being conveyed;
• a communication interface;
• and
• a controller,
• wherein the controller is configured to perform:
• transmitting read image data based on an output signal of the image sensor to an image processing device through the communication interface;
• transmitting sensor information indicating whether or not a detection position, on the original sheet being conveyed, of the detection sensor is an overlapped position overlapping with another object to the image processing device through the communication interface;
• receiving interruption command, which is transmitted by the image processing device when the sensor information indicates that the detection position is the overlapped position and when it is determined that a particular fixed object does not exist at the detection position;
• and
• interrupting conveyance of the original sheet by the conveyer when the interruption command is received.
