Description

Scanner shell with buffer action

Technical field

The utility model relates to a kind of scanner shell (housing), and particularly relevant for a kind of scanner shell with buffer action.

Background technology

With significantly improving of work computer performance, and the high development of world-wide web and multimedia technology, except utilizing digital camera (Digital Camera, DC) outside the direct pick-up image pattern, the image input operation of other relevant documents or picture, all need capture the analog image of literal or pattern by optical scanner (Optical Scanner), and convert thereof into digital signal output, help the user on computer or other electronic products, carry out the actions such as demonstration, identification (OCR), editor, storage and output of image archives.

In general, scanner mainly is made of shell (housing) and main body (body).Wherein, shell can be divided into upper shell (up housing) and lower house (down housing).And upper shell is the loam cake of so-called scanner, and lower house is the shell of so-called scanner, have scanning form and in dispose main body.As for main body, then include optical scanning module (chassis), drive unit, linear guide mechanism and control circuit board etc..And the running of scanner, promptly drive the optical scanning module by drive unit, and it is auxiliary by linear guide mechanism, make the optical scanning module to do flyback retrace to the file or the chart that are positioned on the scanning form along linear path, the image that the optical scanning module is scanned by control circuit board is done to export after the image processing at last.And this output is file or chart after scanner scans, the image data of user's gained.

In scanner, for the design that optical scanning module buffering is provided, being provided with usually to pin on drive unit (as step motor) changes apart from (holding torque) structure at present.What Figure 1A showed is that the optical scanning module uses pinning to change apart from structure, the structural representation of the buffering during as mobile stopping.Please refer to Figure 1A, step motor (not illustrating) drives on the gear set of optical scanning module 100, have one and pin the gear set commentaries on classics apart from structure 110, pinning gear set thus changes apart from structure 110 and can move when stopping at the optical scanning module, firm with clamp optical scanning module 100, with usefulness as buffering.

Known except using pinning to change apart from the locked mechanism of structure as optical scanning module 100, also can be in the scanner shell, assembling buffer element (damper).What Figure 1B showed is that the optical scanning module uses the buffer element of being assembled in the scanner shell, the structural representation of the buffering during as mobile stopping.Please refer to Figure 1B, be assembled with buffer element 130 in the scanner shell 120, and optical scanning module 140 thus buffer element 130 divide its acting force when stopping that loosing equally, with usefulness as buffering.

Yet the known practice but has following shortcoming:

1, gear set is pinned in known use changes higher apart from the cost of structure, and pins gear set and change apart from comparatively complicated in assembling.

2, be known in assembling buffer element in the shell, certainly will increase the cost of this buffer element itself, with and the cost (comprising considering on man-hour and the yield) assembled.
