Document reading apparatus and image forming apparatus

A document reading apparatus, comprising:

• a document reading section reading print information on documents;
• and
• a document feeding section feeding the documents from a state where the documents are stacked in a document stacking tray, in a one-by-one manner, to the document reading section,
• wherein if a document reading instruction is accepted in the state where the documents are stacked in the document stacking tray, a document reading operation is executed successively in which the document feeding section feeds a sheet of document to the document reading section to undergo reading operation by the document reading section,
• and wherein the document reading apparatus further comprises
• a temperature sensor detecting a temperature of a document feeding path along which a document moves that is fed by the document feeding section as a monitoring temperature;
• a document reading control section causing an interruption of the document reading operation, if the monitoring temperature becomes equal to or more than an interruption temperature threshold value that is set less than a color erasing temperature of erasable ink, until the monitoring temperature becomes less than a restart temperature threshold value that is set to be equal to or less than the interruption temperature threshold value;
• and
• an interruption guide screen generation section noticing of the interruption of the document reading operation if the monitoring temperature becomes equal to or more than the interruption temperature threshold value and generating a screen on which an execution key appears which causes the document reading control section to conduct the successive operation at a regular interval of time and a display section on which the interruption guide screen is displayed, wherein if an operation of the execution key is accepted, the document reading control section continuously executes the document reading operation at the regular interval of time without considering the monitoring temperature until there is no document stacked in the document stacking tray.
