Abstract
A sheet material information detection device has an external force applicator that applies an external force to a sheet material, a drive unit that drives the external force applicator, and an external force detector that detects through the sheet material the external force applied by the external force applicator. The drive unit produces motion vectors in at least two directions including a direction perpendicular to a surface of the sheet material.
Claims7
A sheet material information detection device that detects and outputs sheet material information, the device comprising:
- an external force applicator that applies an external force to a sheet material;
- a drive unit that drives said external force applicator;
- and
- an external force detector that detects through the sheet material the external force applied by said external force applicator,
- wherein said drive unit produces motion vectors in at least two directions including a direction perpendicular to a surface of the sheet material.
