媒体厚検出装置及び画像形成装置
Document Type and Number:
Japanese Patent JP4579312
Kind Code:
B2
Abstract:
A medium thickness detecting apparatus detects the thickness of a recording medium. A displacement section is disposed in a transport path through which a recording medium passes. When the recording medium passes the displacement section, the displacement section displaces in a direction substantially normal to the surface of a recording medium. An amplifying section amplifies a displacement of the displacement section by a predetermined factor. A thickness determining section outputs a signal representative of an amplified value of the displacement. The displacement section may be one of two rollers between which the recording medium passes, and displaces upward when the recording medium passes between the two rollers. Alternatively, the displacement section my be positioned to sit on a stage provided in the transport path such that the displacement section is pushed away from the stage when the recording medium passes between the displacement section and the surface.
