Mvetsetsani kapangidwe ka chala

Monga luso lapamwamba, kusaka kwala kwa zala kumalowa pang'onopang'ono m'miyoyo ya tsiku ndi tsiku, koma anthu ambiri amamvetsetsa pang'ono za malonda apamwamba. Pali magawo angapo a scanner yala, ndipo ntchito zazikulu za gawo lililonse ndi ziti? Ndikhulupirira kuti aliyense akufuna kudziwa.

M'malo mwake, mawonekedwe a chala ali ngati thupi la munthu, lomwe limaphatikizapo ubongo, maso, mtima, mitima ndi ziwalo zina, zitseko zina ndi zigawo za chala. Pofuna kupatsa ogula kuti amvetsetse bwino, mkonzi wotsatirayo udzasunga kapangidwe ka foni ya chala.
Zigawo zikuluzikulu za scanner: board, ma clutch, otongoletsera zala, maikolo achinsinsi, microprocessolor (CPU), fungulo ladzidzidzi. Monga chithunzi cha chala, chinthu chofunikira kwambiri kuyenera kukhala chip. Ngati chiwerengero chozindikirika ndi chambiri, chala cha wina aliyense chitha kutsegula icho, ndiye kuti ntchito ndi chiyani? Kachiwiri, ziribe kanthu kuti ndi lokonji, ndiye kuti ndiye kuti ali ndi mankhwala.
Mutu wa zala nthawi zambiri umagawidwa m'mutu wamanja wam'manja ndi mutu wa Semiconductor. Mutu wa zala zam'manja uli ndi maubwino okhazikika, kukhazikika komanso kuwononga, koma njira yodziwika ndiyo pang'onopang'ono ndipo kuchuluka kwa chizindikiritso kulinso kwapamwamba. Semiconduct yam'manja ili ndi liwiro lodziwika bwino kwambiri, kuzindikiridwa kwambiri ndi mtengo wotsika, koma pambuyo poti atavala, kachilombo kazakuma kalankhulidwe.
Matupi otumphuka nthawi zambiri amagawika matupi owoneka bwino, kusintha-kukweza matupi ndi matupi owoneka bwino. Thupi loyera limangotulutsa lirime lokhoma pomwe chitseko chikatsekedwa, ndipo kutseka kwamakina ndikosavuta. Thupi lokhazikika limafunikira kuti musinthe chogwirizira kuti mutulutse pazithunzi zokhoma mukatseka chitseko, zomwe zikutanthauza kuti chitseko chiyenera kukhala pamanja mutatseka chitseko. Thupi lamagetsi oyendetsedwa ndi masinthidwe oyendetsedwa, mutatseka chitseko, gawo lamagetsi limagwira ntchito, ndipo lilime lako lotsekedwa limangotsekedwa pomwe lilime lokhoma litapezeka. Lilime lokhoma la mtundu uwu ndi laling'ono, ndipo ndodo zapamwamba ndi pansi zimayenera kuchotsedwa nthawi yokhazikitsa.
Chotseka pachimake chagawidwa m'khola loona ndi loko labodza. Chophimba choona chowoneka bwino ndicho chopopera chomwe chimadutsa m'thupi la lotchi, pogwiritsa ntchito kalasi ya B Khope, ndi magesi otsutsa, ndipo sikophweka kutsegula ndi kiyi. Zovuta ndikuti mtengo wake ndi wokwera, ndipo mtengo wa mtundu uwu wa scanner yala silotsika mtengo. Loko lonama ndi chojambula chobowola chomwe chimayikidwa kuchokera pansi pa gululo osadutsa chitseko, ndipo makamaka amagwiritsa ntchito kalasi yokhota. Mtundu wokhota uwu umabisala bwino ndipo ndi wotsika mtengo. Koma chifukwa cha izi, zimakhala zosavuta kuti akuba awonongeke m'nyumba mwanu, ndipo chitetezo chimasokonekera kwambiri.
