Abstract
A scanner optical module has a single transmission axle used to support a scanning module (containing a traditional optical device or CIS). The scanning module has a plurality of protrusions (or rollers) slidably (or rotatably) contacting the transparent document platform (view). The scanner optical module has fewer assembled components, a simpler structure, a decreased material cost and production cost, and is modular.
Claims13
A scanner optical module comprising:
- a top cover;
- a transparent document platform installed under the top cover for receiving documents;
- a scanning module installed under the transparent document platform for reading document image data, wherein the scanning module has a sliding groove arranged on a bottom side and middle portion thereof, and the sliding groove has a plurality of contact points formed on an inner wall thereof for point contact between the sliding groove and the transmission axle;
- a transmission axle installed under the scanning module, and having two sides fixed into an inner side of the top cover;
- a plurality of protrusions installed flexibly on the scanning module, and contacted slidably to the transparent document platform;
- and
- a drive device connected to the scanning module for driving the scanning module to move along a scanning direction,
- wherein the sliding groove is a completely covered hollow groove or a half-covered hollow groove, and has concave oil storage tanks formed between the sliding groove and the transmission axle, the sliding groove slidably matching the transmission axle, and the concave oil storage tanks storing lubricant for self-lubrication of the scanner optical module.
