Abstract
The present invention provides an apparatus for discriminating the kind of a sheet material, comprising: a substrate having a recessed portion; a press member situated so that a sheet material can be deflected using the recessed portion; a support member that is deformed as the sheet material situated to cover the recessed portion is pressed by the press member and thereby deflected; and a sensor for detecting the deformation amount of the support member, wherein the kind of the sheet material is discriminated on the basis of detecting the deformation amount of the support member by the sensor.
Claims8
An apparatus for discriminating a kind of a sheet material, comprising:
- a first roller having a recessed portion;
- a press portion situated so that a sheet material can be deflected using the recessed portion and containing a second roller being held by a press portion holding means;
- and
- a deformation amount sensor for detecting a deformation amount of the elastic member,
- wherein the press portion is coupled with the elastic member that is deformed as the sheet material situated to cover the recessed portion is pressed by the press portion and thereby deflected, and a kind of the sheet material is discriminated on basis of detecting the deformation amount of the elastic member by the deformation amount sensor.
