The reading section reads images of respective pages of a spread document one at a time. The orientation detecting section sequentially detects orientations of respective images read by the reading section. The orientation determining section determines whether or not the orientation detecting section detects orientation alternation between a first orientation and a second orientation opposite to the first orientation for a read image read by the reading section. The notification section notifies an error upon the orientation determining section determining that the orientation detecting section does not detect orientation alternation between the first orientation and the second orientation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Document reading device that detects orientation of image read from spread document","description":"A document reading device includes a reading section, an orientation detecting section, an orientation determining section, and a notification section.
