Yet the existing scanner that is installed in the host computer housing how can only scanning reflection formula file, and such as the file that light tight materials such as paper, photograph, business card are formed, reason is the position of light source, and many places are at the homonymy of scanned scanning plane.But for the transparent mode file, for example file such as transparency or lantern slide is not to scan, and servicing unit that exactly must external scanning transparent mode file scans, and not only causes cost waste, and extra servicing unit also need occupy additional space.In addition, the employed resolution of reflective file is not enough for the transparent mode file, thus also can't shared same camera lens, so this scanister can not scan transparent mode and reflective file simultaneously.
The object of the present invention is to provide a kind of scanister that can scan the transparent mode file again can scanning reflection formula file, its structural change design is also little simultaneously.
The object of the present invention is achieved like this, a kind of multisolubility scanner with single lamp tube promptly is provided, it can be fixed in the host computer housing and can utilize a light source scanning by reflective material and transparent mode material make scanned, this scanister comprises at least: a feed arrangement, and this is scanned to be used for input; One image taking device, it comprises at least: one is used to produce light beam is projected to scanned light source; One is used to reflect the above-mentioned reflection unit that is projected to scanned light beam, and it has a plurality of catoptrons, and a spectroscope or a rotatable catoptron; One is used to import the imaging device of described reflection unit beam reflected, to produce an imaging signal; Reach one and be used to import this imaging signal to form the image-taking device of this image, this image taking device utilizes its light source to produce this scanned image, this image taking device is according to scanned unlike material, by the scanning light beam that different direction inputs has this scanned picture signal, make the light path of this scanning light beam process look scanned be reflective material or transparent mode material difference; An and gearing, be used to drive this feed arrangement, make its input the scanned operational movement of also controlling the scanned image taking device of passing through simultaneously, this operational movement of passing through the image taking device continue to carry out up to scanned all finished by image taking device scanning shoot till.
The advantage of multisolubility scanner with single lamp tube of the present invention is, move under the situation of its position at the neither need of all elements, only utilize single light source, make catoptron cooperate utilization with lens, therefore scanning transparent mode is to pass through different light paths to carry out with reflective file, thereby has reduced the manufacturing cost of scanner and reduced the overall volume of scanner.
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment, in the accompanying drawing:
Figure 1A is the side sectional view of first preferred embodiment of multisolubility scanner with single lamp tube of the present invention;
Figure 1B is the another kind of modification structures of scanister shown in Figure 1A;
Fig. 2 A is the vertical view cutaway drawing of second preferred embodiment of multisolubility scanner with single lamp tube of the present invention;
Fig. 2 B is the side sectional view of scanister shown in Fig. 2 A.
Figure 1A is the side sectional view of first preferred embodiment of multisolubility scanner with single lamp tube of the present invention, and Figure 1B is the another kind of modification structures of Figure 1A, wherein all elements shown in Figure 1A have been done the arrangement of turning upside down, the applicable cases of visual reality is done one and is selected between the two.
When scanned 108 were the transparent mode file, the light path of scanning will be via light source 102, scanned 108, catoptron 101, lens 104, spectroscope 105 to charge-coupled device (CCD) 106; When scanned 108 are reflective file, light path will be via light source 102, scanned 108, catoptron 103 and 109, lens 107 to charge-coupled image sensor 106, therefore for scanning reflection formula file and transparent mode file, the light path of process with different.110 of the loam cakes of pallet are used to flatten scanned 108 so that scanning.
After fully utilization spectroscope 105 can be imported the characteristic of light source by both direction, make all scanning light beams all enter same charge-coupled image sensor 106, so though scanned 108 material how, the neither need of all elements move its position.In addition, the resolution of lens 104 will because the transparent mode file is less mostly, need higher resolution could obtain gratifying result than spectroscope 105 height.
Moreover, because spectroscope 105 can in order to obtain more accurate scanning result, can set up mask before the light beam source of spectroscope 105, and screening resistance light beam enter spectroscope 105 in due course at the both direction receiving beam.For example, set up mask 111 between lens 107 and spectroscope 105, be used for when scanning transparent mode file, break beam enters spectroscope 105 via lens 107; And between lens 104 and spectroscope 105, set up mask 112, and being used for when scanning reflection formula file, break beam enters spectroscope 105 via lens 107.But when scanning reflection formula file, owing to light beam is interdicted by this reflective file, so mask 112 also can omit.
