Abstract: A sheet detecting device includes a lever provided with a rotational shaft, a spring and a stopper. The lever is positioned in a stand-by position in a state of being in non-contacting with a sheet, and rotates about the rotational shaft from the stand-by position in a first rotational direction by being contacted with the sheet fed. The spring urges so as to rotate the lever in a second rotational direction opposite to the first rotational direction. The stopper restricts rotation of the lever beyond the stand-by position in the second rotational direction by being contacted with the lever after contacting of the sheet with the lever. A direction of a first force acting on the rotational shaft by the spring in a case in which the lever is positioned in the stand-by position is the substantially same direction as a direction of a second force which the lever receives from the stopper when the lever is in contact with the stopper by rotating in the second direction.

Abstract: Techniques are described for printing on front and back surfaces of security document substrates in a manner that conserves use of print ribbon, thereby extending the life of the print ribbon. In general, the printer controller knows the content, as well as locations and colors, of what has been printed on the front or first surface of the security document substrate.

For locations where there would be no overlap, the printer can reuse the section of print ribbon that was used to print on the front surface to print on the back surface.
