The method includes: controlling a scanning element to scan light at an edge of a platen to obtain a signal value representing a light intensity; determining whether an absolute difference value between the signal value and a preset standard value is greater than a preset tolerance value; sending a prompt signal to prompt a user to close the platen cover plate in response to the absolute difference value being greater than the preset tolerance value; and continuing to perform scanning work on a manuscript on the platen in response to the absolute difference value being not greater than the preset tolerance value. The influence on quality of the scanned image due to incomplete closing of the platen cover plate is prevented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for detecting open and closed states of platen cover plate of image reading apparatus","description":"Provided is a method and a device for detecting open and closed states of a platen cover plate of an image reading apparatus.
