IMAGE SCANNER
Document Type and Number:
WIPO Patent Application WO/2006/118000
Kind Code:
A1
Abstract:
An image scanner which has an improved constant speed characteristic and provides an excellent diagnostic image having no image nonuniformity. The image scanner is provided with an optical unit (1), which irradiates a photostimulable phosphor plate (P) with exciting light (L1) from a light source while performing scanning, collects photostimulated luminescence light emitted from the photolstimulable phosphor plate (P), performs photoelectric conversion and reads image information; a linear motor (7) for moving the optical unit (1); a wire (6) which moves with the optical unit (1); a pulley (52) which rotates by transmission of movement of the optical unit (1) through the wire (6); a rotary encoder (51) for detecting the rotating speed of the pulley (52); and a control means (100) for controlling the linear motor (7) based on the detection results of the rotary encoder (51). The wire (6) is wound around the shaft of the pulley (52) one turn or more by being inclined to be at a prescribed angle from a line (A) orthogonally intersecting with a rotating axis of the pulley (52).
