Ngeminyaka yee-1920, indawo yokugcina i-Woodning Woodle yaqala ukuvela kwiivenkile zeShishini yaseMelika-zilungele iFluoroscope. Umgaqo wokusebenza ulula: Ukufaka umlenze kwigumbi elingaphantsi kwegumbi, umthengi onokubakho wabonakala kwityhubhu ekhethekileyo indlela ezihamba ngendlela enyaweni. Isixhobo esikhwaza ngonyawo, ukuze ubone ithambo ngalinye kunye nolwahlulo lwedwa.
Le yindlela echaza ngayo i-vladimir nabokov kwi "Dara":
"Umlenze wangeniswa ngokungummangaliso, kodwa ngokungenamfti, imfanyekiswe ngokupheleleyo: Ukuhamba kweminwe engaphakathi kwakungabonakali kwindawo egudileyo yolusu. I-Sleslewoman enesantya esimnandi sankqonkqoza iziphelo ze-lace-kwaye ichukumise i-sock Shoe ngeminwe emibini.
"Kuphela!" Uthe. "Intsha rhoqo ..." Waqhubeka nokuhamba ngokungxama, esongela amehlo amdaka. Kodwa banokuthi, bazibonele ngokwakho ! " Kwaye wamkhokelela kwi-X-ray, wabonisa ukuba angalibeka phi umlenze. Ukujonga efestileni ezantsi, wabona eyakhe, emnyama, eyahlukileyo - eyahlukileyo kwimvelaphi yokukhanya.
Esi sixhobo saqala ukubamba ngokoqobo iivenkile zeSwee Merika naseYurophu. ENgilani, wabizwa ngokuba yi-Pedoyiscope, eJamani - i-sucoskope. Ixabiso le "Shoe Shoe" nge-X-ray eyahlukileyo kwi-800 yeedola ukuya kwi-1000 yeedola.
Ngaphandle kweendleko eziphezulu, umnini-mpahla ngalunye ufune ukufumana i-novelty yesimo. Incopho yokuthandwa yeza kwiminyaka yoxinzelelo olukhulu: Abantu babefuna ukukhetha izihlangu ngengqondo ukuze zinxitywe kunelo xesha elinye. Ishishini labanini be-pedoscopes lalimangalisa, ngelixa ngasekupheleni kweminyaka yee-1940, izazinzulu azithethi ngendlela ezingambi kuzo ezi zixhobo.
Abazange bacinge izoyikiso zabathengi: ubuncinci kwakungekho nzamo. Uninzi lwabathengisi babandezeleka, izandla zabo bawa phantsi kwefuthe ngqo lemitha (umyinge we-114 MD / H), xa bawela iinyawo zabo zabathengi. Oku kukhokelele kwi-dematitis kunye nezinye izifo zolusu. Enye yezona zinto zisenzakeleyo kakhulu ezinxulunyaniswa nomsebenzi we-Pedroscope zarekhodwa kwimodeli yesihlangu, ethi ngenxa yemitha yokulinganisa ihlawulwe umlenze.
Abenzi behlabathi liphela ngokuthe ngcembe baqala ukunciphisa ukusetyenziswa kwee-pedoscopes (ke, abantwana abanokuzisebenzisa nje izihlandlo ezili-12 ngonyaka, abangakhange balingane nabathengisi), ngenxa yoko banyamalala ngokupheleleyo kwiivenkile ngo-1960, kwaye ngaphakathi I-UK kunye neCanada-ngo-1970 -m.
