Falt bed scanner
Technical field
The present invention is a kind of falt bed scanner, and finger is applied to the falt bed scanner between object to be scanned and the computer especially.
Background technology
Along with the progress of digital information transmission, the application of image processing output input is also more and more general.Just general institute is known, and scanner enters volume production already and makes manufacturing cost reduce, and has been widely used in commercial use and the domestic use, as capturing very convenient means of digital image file.
See also Fig. 1, it mainly describes the schematic perspective view of a known scanner 10.The main composition assembly of this known scanner 10 includes soft arranging wire 17 that a ray machine 11, a belt conveyor 12, a belt bearing 13, a slide rail 14, a motor 15, one scan platform (being generally a clear glass) 16, data delivery use and data output connectivity port 18 etc.Wherein an end of this ray machine 11 is fixedlyed connected with this belt conveyor 12, and activity is sleeved on this slide rail 14, and 17 of this soft arranging wires are finished and are electrically connected between this ray machine 11 and this data output connectivity port 18.
Please further with reference to figure 1, when using this known scanner 10 to scan, the object 21 that the user will desire scan image places on this scanning platform 16, and by 15 runnings of this motor and drive this belt conveyor 12, and then drive these ray machines 11 by this belt conveyor 12 and slide along this slide rail 14 in this scanning platform 16 times, and can upwards progressively scan this object 21.The DID of this ray machine 11 scanning gained transfers to this data output connectivity port 18 by this soft arranging wire 17, and transferring to this computer 19 by a data line 20 that is connected in this data output connectivity port 18 and this computer 19 (as the USB transmission line etc.) at last becomes image file.
Yet, use as during the known scanner 10 of above-mentioned this, problem as described below can take place: please refer to Fig. 2, because when using 10 pairs of these objects 21 of this known scanner to carry out scanning operation, the scope that this ray machine 11 is moved must contain whole this scanning platform 16, and transfer of data must be exported this soft arranging wire 17 of connectivity port 18 with these data by being connected in this ray machine 11, have under the different situations along with moving of this ray machine 11 in the distance of this ray machine 11 with 18 of this data output connectivity ports, the length of this soft arranging wire 17 also must be arranged sufficient length to connect this ray machine 11 and be exported the maximum distance of connectivity port 18 with these data.But thus, when ray machine 11 moves to position near this data output connectivity port 18, this soft arranging wire 17 can have the situation of curling perk because of length is long, so the friction reciprocal with this scanning platform of top 16 takes place easily, cause the generation of the trace that rubs and influence the problem of scanning quality, its thin portion situation please refer to Fig. 3, schematic diagram for this soft arranging wire 17 and the 16 generation frictions of this scanning platform, by shown in the figure as can be known when this ray machine 11 moves, this soft arranging wire 17 of curling perk can touch this scanning platform 16, thereby causes friction.
