Abstract

The invention provides a recording medium removing apparatus, an erasing apparatus, an automatic document feeding apparatus and a recording medium removing method. The erasing apparatus with the recording medium comprises: a recording medium conveying mechanism configured to convey the recording medium; a first thickness sensor configured to change an output signal if the thickness of the recording medium is equal to or larger than a first threshold; a conveyance guide provided downstream in a recording medium conveying direction of the first thickness sensor and forming a recording medium conveying path; a conveyance guide displacing device configured to displace the conveyance guide to expand the recording medium conveying path; and a heating roller configured to heat the recording medium to temperature equal to or higher than erasing temperature.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on and claims the benefit of priority of US Patent Application No. 61 / 314111, filed March 15, 2010, and US Patent Application No. 61 / 314,113, filed March 15, 2010, the entire contents of which are incorporated herein Reference. technical field [0003] The present invention relates to a recording medium removing apparatus, a decolorizing apparatus, an automatic document feeding apparatus, and a recording medium removing method. Background technique [0004] In order to save resources, decolorizable developing materials are often used for image formation. As an erasable developing material, there are toners, inks, and the like which can be dissipated by heat. The recording medium on which the image is formed using the decolorable developing material is heated by the decolorizing device, and can be reused after decolorization. [0005] However, the recording media put into the erasing device a...
