Abstract
The present invention relates to a light gathering apparatus of a scanner. A light source module of the light gathering apparatus is independently separated from a scanning module to make the light source module fixed in a main body of the scanner, and then a light gathering component and a light guide component are used for guiding a light source onto a scanning line of an original manuscript. Because the light source module is independently separated from the scanning module, the miniaturization design of the scanner is preferable, and heat dissipation is easy. Accordingly, noise or deformation generated by the heat exposure of a charged coupled device, a reflecting lens or a main body of the scanning module can be reduced.
Description
Technical field
The present invention relates to a kind of scanner light collecting device (Light Gathering Apparatus), particularly relate to a kind of with light source module from the independent scanner light collecting device of scan module.
Background technology
At present, the scanning light source of scanner generally is installed on the interior scan module of scanner main body, and adopts cold-cathode tube as scanning light source mostly.See also Fig. 1, it is the generalized section of existing scanner device.General scanner 100 mainly is made of main body 102, includes scan module 104 in the main body 102, and the light harvesting reflector plate 108 that is equiped with the light source 106 of scanning on the scan module 104 and is positioned at light source 106 belows.110 of the original copys that need scan are placed on the original copy face 114 of main body 102.
When carrying out the scanning of original copy 110, light source 106 emits beam 112, the light 112 direct directive original copys 110 of part, and the light 112 of another part reflexes on the original copy 110 after the light harvesting reflector plate 108 of light source 106 belows is assembled.At this moment, scan module 104 is advanced towards direction 118 in main body 102, so that the light 112 inswept whole part of original copys 110 that light source 106 is sent.After treating light 112 inswept whole part of original copys 110, scan module 104 is advanced towards direction 116, gets back to the preceding ready position of scanning.Penetrate on original copy 110 light 112 after reflection, the reflection of the image that produced enters scan module 104, again after scan module 104 is handled, forms digital image signal and finishes scanning.
Yet, under the situation of pursuing more compact scanner assemblies, the space that can be used to the config set optical assembly on the scan module is more and more little, because the light source module of light collecting device is arranged on the scan module, thereby cause the light harvesting area to reduce, and then cause the service efficiency of light source to descend.
