Abstract
Provided are a sheet processing device and a sheet manufacturing apparatus capable of removing color material from printed parts without excess or deficiency. A sheet processing device has a detector configured to detect a printed part printed on a sheet; and an eraser configured to selectively remove at least a surface part of a printed area including the printed part detected by the detector. The eraser includes a grinding tool to grind the sheet, and a pressure mechanism configured to selectively increase contact pressure between the sheet and the grinding tool in the printed area.

A sheet processing device comprising:
- a detector configured to detect a printed part printed on a sheet;
- and
- an eraser configured to selectively remove at least a surface part of a printed area including the printed part detected by the detector, wherein:
- the eraser includes a grinding tool to grind the sheet, and a pressure mechanism configured to selectively increase in the printed area contact pressure between the sheet and the grinding tool,
- the pressure mechanism has a pressure member disposed movably to and away from the grinding tool, and directly or indirectly applies pressure to the sheet from the opposite side of the sheet as the grinding tool, and
- the pressure member has multiple pressure elements, and selectively drives the pressure elements to increase contact pressure of the grinding tool to the sheet in parts.
