Problems solved by technology

[0004] However, in the workflow of erasing written parts by heating the paper with other devices after being read and digitized by a scanner, it is impossible to ensure reliable erasure after reading and digitizing
In addition, if the storage period from reading and digitizing to erasing is too long, this alone increases the possibility of information leakage

Abstract

An image reading apparatus comprising: an automatic document feeding apparatus which conveying a document that has a part written by pigment that becomes colorless when heated and is loaded in a document tray to a sheet discharge location via a conveying path that passes through a prescribed reading out position; a reading section for obtaining an image information by reading out optically from the document which is conveyed by the automatic document feeding apparatus at the reading out position; a storage section for storing the image information obtained by reading the document in the reading section; and a heating unit for heating the document in a temperature of the pigment becomes colorless on a downstream side of the reading out position while the document passing through the conveying path.

Description

technical field [0001] The present invention relates to an image reading device for optically reading a document, in particular to an image reading device suitable for reading a document including a portion drawn by a paint that becomes colorless when heated. Background technique [0002] Conventionally, there is a writing tool using ink that becomes colorless when heated to a high temperature such as 60° C. or higher from the viewpoint of effective utilization and recycling of paper resources. In addition, there is an inkjet printer that has a recording unit that uses ink that is heated and becomes colorless, and a heating unit that is arranged in front of the recording unit and that turns the ink into colorless (for example, refer to JP Patent Publication 2001-302954 Bulletin). [0003] When personal information written on questionnaire paper, etc. is read with a scanner, digitized, and stored in a database for management, it is required to properly handle the digitized p...
