A color erasing apparatus

摘要

According to one embodiment, a color erasing apparatus includes a color erasing section, a first conveying section, a reading section, and a second conveying section. The color erasing section erases a color of an image formed with an erasable color material on a sheet conveyed at first speed. The first conveying section includes a first conveying roller arranged downstream in a sheet conveying direction of the color erasing section and configured to convey the sheet and a first driving section configured to drive the first conveying roller. The first conveying section conveys the sheet, which passes through the color erasing section, at the first speed. The reading section reads an image on the surface of the sheet conveyed at second speed higher than the first speed. The second conveying section includes a second conveying roller arranged upstream in the sheet conveying direction of the reading section and in a position where the second conveying roller nips the conveyed sheet in cooperation and simultaneously with the first conveying roller and a second driving section configured to drive the second conveying roller. The second conveying section conveys the sheet to the reading section as the second speed.
