Abstract
A medium conveyance device includes a drive roller that conveys an original in first direction, a guide in which a first surface and a second surface are formed, a slider in which a first point and a second point are formed, a pinch roller that is rotatably supported by a pinch shaft that is fixed to the slider and that pushes the original against the drive roller, and a sensor that measures a thickness of the original based on an amount of move of the slider in a second direction that is different from the first direction, wherein the first point slides on the first surface and the second point slides on the second surface and accordingly the slider is supported on the guide movably in the second direction and a distance between the first point and the second point is longer than a diameter of the pinch shaft.
Claims5
A medium conveyance device comprising:
- a drive roller that rotates;
- a guide in which a first sliding surface and a second sliding surface are formed;
- a slider in which a first contact point and a second contact point are formed;
- a pinch roller that is supported on the slider rotatably via a pinch shaft and that pushes an original against the drive roller;
- and
- a sensor that measures a thickness of the original based on an amount of move of the slider in a second direction that is different from a first direction in which the original is conveyed,
- wherein the slider is supported on the guide such that the first contact point slides on the first sliding surface and the second contact point slides on the second sliding surface and accordingly the slider is movable in the second direction, and
- a distance between the first contact point and the second contact point in the second direction is longer than a diameter of the pinch shaft.
