Sikukhombisa ifayili le- izinhlobo zeskena, okukhona njengamanje futhi sikwazisa nosizo olukhulu olunikezwa yilezi zinsiza, ngemisebenzi yazo eyahlukahlukene, abayinikezayo lapho kudinga ukuskena noma yiluphi uhlobo lwedokhumende kusuka kumatheksthi kuya kumafilimu.
Izinhlobo zeskena
Emvelweni yamakhompiyutha kunezinombolo zezinhlobo zama-scanner, zingamadivayisi awusizo anomsebenzi wokuskena noma yimuphi umbhalo onolwazi olufanele kusuka ezithombeni kuya kumatheksthi.
Yikhompiyutha enomsebenzi ofana ne-photocopier, kuyo idokhumende elizoskenwa itholakala ekusekelweni okukhethekile, isoftware efakiwe iyaqhubeka nokufunda okuqukethwe, idlule kukhompyutha futhi ikucubungule ikhombisa umphumela wokugcina ongu Idokhumenti eskeniwe.
Kunezinhlobo eziningi zeskena ezingasetshenziselwa imisebenzi yasehhovisi, ekhaya, lawa makhompyutha anoxhumano lwe-USB, futhi anikeza umsebenzisi imisebenzi eminingi ewusizo eyenza impilo yalabo abayisebenzisayo ibe lula futhi isebenze ngokwengeziwe.
Ngokulandelayo sizokhombisa izinhlobo ezahlukene zeskena ezikhona emakethe, siqala ngo:
Isithwebuli sethebhulethi noma isithwebuli se-flatbed
Lolu hlobo lwesithwebuli lunomthombo wokukhanya, kanye nenzwa yokukhanya ye-CCD, eyingxenye yengxenye ye-bravo ehambayo, umsebenzi wayo ukudlula kumbhalo obekwe ekusekelweni kwengilazi.
Amaskena wethebulethi ngamadivayisi anconyelwe kakhulu ukuthi asetshenziswe ekhaya, awaziwa kakhulu, ngaphandle kokuthi ukuphatha kwawo kulula futhi kunikeza umkhiqizo osheshayo ngaphandle kwezinkinga eziningi.
Iskena sencwadi
Luhlobo lwethuluzi olunobukhulu obukhethekile bokuskena izinhlobo ezahlukene zezincwadi, futhi lunokusekelwa kwe-sheet feeder, amashidi ezincwadi adinga ukuskenwa abekwa phezulu engilazini.
Ilensi yokufunda ifakwa ngaphansi kwepuleti lengilazi, kanye nengalo edlula kuyo yonke indawo, iskene idokhumenti ngokunembile nangokucacile.
Isithwebuli seDrum
Lolu hlobo lwesithwebuli lusetshenziselwa kabanzi ukwenza imisebenzi emikhulu futhi lunikeza nemiphumela ngekhwalithi ephezulu kanye nokuxazululwa, yize izinga lalo lokucubungula lihamba kancane, ukuliphatha kwalo kubalulekile ukuthi kwenziwe ngungoti.
Inesistimu yokudlulisa eyenziwe ngemifanekiso ehamba kancane iphoyinti ngalinye, ngaleyo ndlela ifinyelele kwisinqumo esihle.
Isithwebuli seMicrofilm
Isithwebuli se-microfilm sisetshenziswa ikakhulukazi ukwenza i-microfiche yedijithali, ama-roll films kanye namakhadi wokuvula, anokucaca ukuthi awanikeli ngezinga elihle lokufakwa kwedijithali, kodwa-ke, konke kuzoya ngekhwalithi nesimo sokuthi i-original ikanjani.
Iskena sesilayidi
Leli thuluzi lisetshenziselwa ukufaka amakhompyutha kumaslayidi aseprintiwe, kanye nemibhalo enezinhlangothi ezintathu kanye nolunye uhlobo olufanayo lwedokhumenti, kuphakanyiswa kubasebenzisi ukuthi ngasizathu simbe kumele bagcine izithombe ezifanele zezithombe ukuze bazenze nalolu hlobo ithuluzi.
Iskena esiphathwayo
Lolu hlobo lwesithwebuli esiphathwa ngesandla lunezethulo ezimbili: imibhalo kanye nezikena ze-3D, ezibhekisa kumadivayisi wezandla aqhutshwa yibo bonke ubuso bedokhumenti eskenwayo, ukwenza ukuskena kwale mibhalo futhi ngaleyo ndlela kudingeke ukunemba. Ngaphandle kwalokho imiphumela ngeke kufinyelelwe.
Ama-scanner aphathwayo anekhadi lawo, futhi lawa madivayisi anenketho yokuthi angaxhunywa ngqo kubaphrinta bekhompyutha, ingenye yezinhlobo ezishibhile futhi okulula ukuwaphatha, noma kunjalo anikeza isisombululo esiphansi.
Iskena se-3D
Lolu hlobo lwesithwebuli lusebenza ngokwenza izilinganiso emabangeni amade futhi ngokusho kwama-engeli ukuthi lwenzani ngogongolo lwe-laser, le divayisi inomsebenzi wokucubungula idatha eyanele, kanye nokuhlaziya izinto ezisezindaweni ezahlukahlukene, inokubaluleka kwe ukujoyina imininingwane ezoskenwa ngokuya ngobunjalo bayo namathoni.
Sikunikeza i-athikili ehlobene nendaba njengoba injalo Yini imodeli engu-3d.
Ngokuvamile, leli thuluzi lisetshenziswa kakhulu ezimbonini ezinikezelwe kwimetroloji, nasezimotweni, linikeza ithuba lokuqopha indawo ebonakalayo enemininingwane, isivinini nokunemba, kanye nokuthwebula ukuxhumanisa kwezindawo okukhona kuso isifunda esilinganiselwe .
Inekhono lokusebenza ngemizuzu ngaphandle kokuxhumana nezakhi, phakathi kokuhle kwayo kungabekwa amakhamera.
Iskena Sevidiyo Yedijithali
Lolu hlobo lwesithwebuli lusetshenziselwa ukwenza amadokhumende anezinye izinhlelo zokusebenza zekhompyutha, amakhadi angahlanganiswa ukufakwa kwedijithali izithombe ngasikhathi sinye lapho eziguqula zibe yimifanekiso ye-analog electronic.
Dlulisa isithwebuli
Phakathi kwemisebenzi yayo inedizayini ekhethekile yokuthwebula amafilimu asobala, ishiye ithoni enayo, uma ingekho kahle, ilungele lolu hlobo lomsebenzi.
Iskena sebhakhodi
Yimishini esetshenziswa ezitolo ezahlukahlukene ezinikezelwe ukuthengiswa kwanoma iyiphi into engafakazelwa ukuthi kubekwa ikhodi efakwe ekhompyutheni efundwa kukhompyutha, evumela ukulawula izintengo nokufakwa kwempahla.
Iskena se-ID
Lolu hlobo lwesithwebuli lusetshenziswa ikakhulukazi ezindaweni ezithile, lapho kuhlolwe ukungena kwabantu ezindaweni ezithile, kunomsebenzi wokuskena abantu ngezigxivizo zeminwe, ebusweni babo nakwezinye izingxenye zomzimba, okwenza kube lula ukufaka ukufaka.
Isithwebuli somzimba
Yimishini evame ukusetshenziswa ezikhumulweni zezindiza, inomsebenzi wokuskena wonke umzimba womuntu, ukuthola noma yini engafanele.
Iskena esiphathekayo
Zingamadivayisi alula futhi asebenzisekayo ukuthutha, anezilinganiso ezingalungiswa ngaphandle kobunzima obukhulu, umsebenzisi angakwazi nokuziphatha ephaketheni, amelwe ezibayeni futhi ahlole imininingwane ngemigqa.
Siyini isithwebuli?
Isithwebuli iyithuluzi lokufaka ulwazi elinomsebenzi wokuthwebula izithombe zanoma yiluphi uhlobo bese uzifaka e-plasma ephepheni esithombeni sedijithali.
