Abstract
The utility model relates to a light source of a scanner. The utility model causes the light ray of the light source to be better utilized in scanning. A light source device of an optical scanner comprises a scanner casing and a scanning die set in the casing; the light source device comprises a sliver-shaped lamp tube, a sliver-shaped shade and a light condense lens. The utility model is characterized in that the sliver-shaped shade is provided with a bar-shaped opening and a sliver-shaped groove which is positioned at the inner side of the opening, and the cross section of the sliver-shaped groove is approximate to a circular arc shape; the sliver-shaped lamp tube is fixed in parallel in the sliver-shaped groove of which the inner surface is a smooth reflecting curved face; the light condense lens is arranged at the sliver-shaped opening point of the sliver-shaped shade. The utility model is used for the optical scanner.
Description
The utility model relates to the light supply apparatus that optical scanner is used.
The light supply apparatus of existing optical scanner is shown in Fig. 1-4: Fig. 1,2, and light supply apparatus 40 is a strip fluorescent tube 42 just, shot file 22, light 44 only sub-fraction shines file upper tracer zone 24, and major part has all dissipated, and does not effectively utilize; Fig. 3,4, optical devices 50 comprise a fluorescent tube 42 and and are located at fluorescent tube 42 reflector plate 52 on every side, shot file 22, and light 44 is understood some and is reflexed on the file scan line zone 24 through reflector plate 52, and still having partly, light dissipates utilization not yet in effect.
The purpose of this utility model provides a kind of light supply apparatus that effectively utilizes the optical scanner of light preferably.
The purpose of this utility model is achieved in that the light supply apparatus of optical scanner, comprises the scanning module in one scan device housing and the housing; Light supply apparatus comprises a strip fluorescent tube, a strip shade and a concentration piece; It is characterized in that: the strip groove that is positioned at the opening inboard of a strip gab and an xsect approximate circle arc is arranged on the strip shade, and the strip fluorescent tube is fixed in the strip groove that inside surface is level and smooth reflecting curved surface abreast; Concentration piece is put the strip opening part of strip shade.
Above-mentioned design, the light that mat shade, lens etc. send the light source fluorescent tube through reflection, focusing, has reached the effect of utilizing light preferably.
Be described further again below by accompanying drawing, embodiment.
