Abstract

A scanning device with a floating light source includes a casing, a transparent plate, an image capture module, a light source module and an elastic component. The transparent plate for carrying the original is installed at the opening of the casing to seal the opening. The image capturing module is installed in the casing so as to be movable in the first direction, and is used for capturing the image of the document. The light source module is movable and installed on the image capture module toward a second direction substantially perpendicular to the first direction, and is used for emitting light to illuminate the original. The elastic component connects the light source module and the image capture module, and is used to push the light source module to the transparent plate, and keep the transparent plate and the light source module at a predetermined distance when the transparent plate is not subjected to a specific force, and the transparent plate is subjected to a specific force. Although the transparent plate is in contact with the light source module when the force is applied, its freedom of movement can still be maintained.

Description

technical field [0001] The invention relates to a scanning device with a floating light source, in particular to a scanning device with a floating light source capable of reducing noise, cost and weight. Background technique [0002] An image capture device, such as a scanner, mainly uses light to irradiate a document, and the reflected or transmitted light enters an optical reading device for optical analysis. For example, the scanner usually has a scanning module, and the scanning module has a light emitting device, such as a linear light emitting device composed of a cold cathode lamp or a light emitting diode and a light guide column. The light-emitting device emits light to irradiate the reflective manuscript, and the reflective manuscript reflects the light back to the scanning module for the image sensor to sense light signals. Improving the luminance of the light emitting device can effectively shorten the scanning time, but it will shorten the life of the light emi...
