Abstract
A sheet separator. The sheet separator includes a main body, a frictional member, and an elastic member. The main body is rotatable with a slot being longitudinally parallel to the moving direction of the medium. The frictional member is disposed in the slot and contacts the medium. When feeding, the medium exerts a first force on the main body through the frictional member. Moreover, the elastic member connects to the main body and exerts a second force thereon. According to the first force and the second force, the angle between the main body and the medium is adjusted.
Claims18
A sheet separator for a media-feed mechanism of an apparatus feeding at least one medium, comprising:
- an arm connected to the apparatus, comprising a slot;
- a frictional member disposed in the slot and contacting the medium, wherein the medium exerts a first force on the arm via the frictional member when feeding;
- and
- an elastic member connected to the arm, exerting a second force on the arm,
- wherein an angle between the arm and the medium is adjusted according to the first force and the second force.
A sheet separator for a media-feed mechanism feeding at least one medium of an apparatus, comprising:
- a main body, having a slot being longitudinally parallel to a moving direction of the medium;
- a frictional member disposed in the slot and contacting the medium, wherein the medium exerts a first force on the main body via the frictional member when feeding;
- and
- an elastic member connected to the main body, exerting a second force on the main body,
- wherein an angle between the main body and the medium is adjusted according to the first force and the second force.
A media-feed mechanism of an apparatus feeding at least one medium, comprising:
- a bottom surface;
- a sheet separator disposed on the bottom surface, comprising:
- an arm connected to the apparatus, comprising a slot;
- a frictional member disposed in the slot, comprising a frictional surface contacting the medium, wherein the medium exerts a first force on the arm via the frictional surface when feeding;
- an elastic member connected to the arm, exerting a second force on the arm;
- and
- at least one rib disposed on the bottom surface to sustain a leading edge of the medium,
- wherein an angle between the arm and the medium is adjusted according to the first force and the second force.
