摘要:
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.

Optical scanning apparatus is disclosed wherein a plurality of reading heads (L, L') are mounted on a rotating support (D), and a light source (LA) directs light through an optical beam switching means (H) which rotates about an axis (A) colinear with that of the support but at half the rotational speed, whereby the reading heads are caused to be successively operational in turn over a given segment of each revolution of the support, which has a linear translational movement relative to image-bearing subject(s) to be read.

A method and apparatus is shown for leading an imaging surface relative to an imaging beam under two controls where first and second leading spaces are produced. The second leading space being a different width than the first leading space, is distributed amongst the first leading space separating a plurality of line pairs. The second leading space is interspersed within first leading spaces and is visually less perceptible to the human eye. A pattern describing a matrix of row and column positions control the spacial movement of an imaging beam and after each leading step the imaging beam reproduces the original graphic within each of the elemental image positions or image areas of the matrix.

An optical scanning technique employs an optical sensor array (54) for collecting image pixel data from a flat medium (10) during a scanning cycle. A motion apparatus (72, 92) provides relative motion between the sensor array and the medium such that a spiral locus is defined by the sensor array relative to the media during a scanning cycle. The spiral maximum diameter may be made equal to the diagonal dimension of a rectangular media, thus allowing pixel data to be collected very close to the edge of the media, and so reducing or eliminating the area of unscannable margins on both sides and the top and bottom of the media. The motion apparatus can include a turntable (80) for rotating the flat medium about a center of coordinates, and a translatable carriage (60) holding the sensor array. An ink jet printhead (40) can be mounted on the motion apparatus, to provide a multi-function scanner/printer machine.

There is provided a compact image transmission and modification device comprising a base element defining on a first surface thereof at least one first array of locations having a first interlocation spacing and defining on a second surface thereof at least one second array of locations corresponding to the first array of locations and having a second interlocation spacing, and a plurality of signal transmission means, each of the means associating a location of the first array with corresponding location of the second array. There is also provided means for imparting to the base element a continuous rotary movement about a rotation axis defined therein, to provide a scanning movement thereof, wherein the image modification produced by the device is substantially a function of the ratio between the first interlocation spacing and the second interlocation spacing.
