Embodiment
The present invention is a kind of scanister with file stationary installation, file can be fixed, and the file stationary installation of scanning system can be separated with scanning system.Scanning system of the present invention can be installed in the computer, and more particularly, scanister of the present invention can be installed in the computer position of installing as floppy disk drive or CD player.
Consult Fig. 1, this scanister 2 comprises a base 100 and a loam cake 118, so that the fixed space of each file of scanister to be provided.Pair of tracks 102 is installed in respectively on the base 100 by supporting seat 105, is used for fixing file stationary installation 200, makes file stationary installation 200 to move linearly along track 102.One flat board 104 has an opening 106, is connected with base 100 and is contained in its front.This opening 106 is used to provide the approach of this scanister of 200 1 turnover of file stationary installation.
Consult Fig. 1 again, on dull and stereotyped 104, be provided with one and move back part button 108, move back and can start one after the part button is pressed and move back part mechanism (showing in detail in the drawings), with file stationary installation 200 by withdrawing from the scanning system 2.Because of this moves back part mechanism is prior art, is familiar with this art person and all understands it, is not described further at this.When moving back the part operation, the user at first presses and moves back part button 108, moves back part mechanism 110 file stationary installation 200 is withdrawed from from scanister 2.In this special instruction, the present invention is not certain need installing moving back part button 108 and move back part mechanism 110.For example, an available fixed hook replaces and moves back part mechanism 110, and the user can take out file stationary installation 200 with manual mode from scanister 2.When the user pushed file stationary installation 200 in the scanister 2, this fixed hook makes can be fixing with file stationary installation 200, and the action of this fixed hook simultaneously can be guaranteed can not move in file stationary installation 200 scanning processes.Loam cake 118 is fixed on the base 100, is used for the All Files of topped scanister 2.
Consult Fig. 1-Fig. 4, in scanister 2, be provided with an image read-out 114.Generally speaking, the manner of execution of image read-out 114 is to hold row level with both hands to move to the other end along one of file plane, reads each bar parallel lines during the course one by one, reads until finishing a complete image of full page.With a preferred embodiment, image read-out 114 is installed in the below of file stationary installation 200 and is driven by a drive unit, this drive unit uses stepper motor 116a, a gear set 116b and driving belt 116c, and the power of stepper motor 116a is passed to image read-out 114 by gear set 116b, driving belt 116c.Image read-out 114 can be done the linear movement of front and back by a slide mechanism as pair of parallel bar 118 under this power drives.This is installed between the supporting seat 105 parallel bar 118.Usually image read-out 114 is to use contact type image sensor (Contact image sensor; CIS).Similarly, also can use charge coupled cell (charge coupled device; CCD) come composing images reading device 114, and installing light source, reflecting optics group and lens group form a complete combination.Using the advantage of CIS is that its light path is shorter, and shared volume is also little than the CCD device, therefore can significantly reduce the volume of scanister.
Consult the synoptic diagram of file stationary installation 200 among Fig. 5, the present invention shown in Figure 6.File stationary installation 200 comprises a transparent plate 200a and the topped device of a file.In an embodiment, the topped device of file comprises a marmem 200b with topped file 300, and a turning axle 200d.The end of marmem 200b then is connected on the turning axle 200d.The film that is usually used in photographic negative also can be used for replacing marmem herein.
When using this scanister, at first file 300 is placed on the surface of transparent plate 200a, the file pattern contacts with the surface of transparent plate 200a.Consult Fig. 6, then file stationary installation 200 is sent in the scanning system 2 along the direction shown in the arrow.When file stationary installation 200 was sent into, marmem 200b was also thereon topped thereupon, so file 300 just can be flattened on the surface of transparent plate 200a.Whether enter in the scanning system 2 the sixth of the twelve Earthly Branches to be installed in scanister 2 interior sensor meeting sensing files, senses file as sensor and enter in the scanister 2 the sixth of the twelve Earthly Branches, and this scanister 2 will start to scanning mode.Stepper motor just can drive image read-out 114 and read image on the file 300, be picture signal with the image transitions on the file simultaneously, this picture signal produces image code through pretreatment unit, analog to digital converter and post-processing unit and exports screen or other output units to.In addition, also CIS can be fixed in the scanner, and when utilizing file 300 feed-in scanners, file 300 is finished scanning with respect to CIS do relative motion.
Consult Fig. 5, wherein file stationary installation 200 can be separated with scanister 2, and when file stationary installation 200 was taken out in the opening 106 of the direction shown in the arrow by scanister 2, marmem 200b can be wound on the turning axle 200d.This moment, marmem 200b reverted to the state that it does not stress.
