摘要:
Apparatus for supporting a scanner head, the apparatus comprising: a carrier assembly (12); a bogey assembly (11); and a scanner head assembly (10), comprising a mounting for holding a scanner head; wherein the scanner head assembly and the bogey assembly are both mounted on spring bearings on the carrier assembly such that they can both move in a vertical direction, and the scanner head assembly comprises at least two collinear vertical bearings (14) which restrict movement of the scanner head assembly to vertical movement substantially perpendicular to a document path, and the bogey assembly comprises two laterally spaced bearings (13) which allow rotational movement of the bogey assembly about the scanner head mounting.

摘要:
When a plurality of multi-contrast images for medical care are printed on one film (F), the name of a patient, etc., for specifying the film (F) is extracted from a plurality of images printed, and it is magnified properly and printed in a predetermined position of the film (F) such as its lower portion. This operation is instructed in advance to an optical processing system.

One or more lenses (10) are revolved around an axis (12) normal to a flat scan plane (21) to provide a scanning mechanism for exposure onto (or reading off of) a flat plane of a substrate (20). The data for the image is remapped electronically or in software to compensate for the curved path (13) of the focal point of the scanning lens. combined with a conventional scanning mechanism (35, 40) in a second axis, an area scan is accomplished inexpensively on a flat plane.

The invention relates to the line-by-line optical scanning of documents and images by means of a sensor. According to the invention, to this end a reference point of the optical axis is displaced along a v-shaped trajectory, whereby the distance from the sensor to the document remains the same. This allows for a very simple mechanical structure for the optical support, which can be part of an articulated quadrangle.

The present invention relates to an optical scanner (20) comprising a radiation source (24) for generating a radiation beam, and means (22, 26) for giving the radiation beam a scanning movement in a first direction through an angular range Δυ1 and in a second direction through an angular range Δυ2. The radiation source (24) is, for example, a diode laser and is tunable in wavelength, and the means comprise a rotating reflecting element and a grating.
