A copying machine wherein sheets stacked in a
sheet cassette are conveyed one by one to a sheet
copying portion to take copies. Between a sheet
supply portion and the copying portion there is
disposed a sheet separating mechanism for separating
plural sheets when taken out at a time from the sheet
supply portion. Further, between the said sheet
separating mechanism and the sheet copying portion
there is disposed a sheet position detecting measure.
Plural sheets delivered from the sheet supply portion
are separated one by one by the sheet separating
mechanism, then after taking synchronism with the
copying portion through the sheet position detecting
measure, each sheet is conveyed, so copying can be
done accurately.
Cette invention concerne une machine à copier alimentée feuille à feuille à partir d'un magasin d'alimentation. Entre la partie alimentation et la partie copiage de la machine se trouve un séparateur servant à empêcher plusieurs feuilles d'arriver simultanément à la partie copiage. De plus, entre le séparateur et la partie copiage se trouve un détecteur de position des feuilles. Les feuilles sortant simultanément du magasin sont séparées par le séparateur qui, après s'être mis en synchronisme avec la partie copiage grâce au détecteur de position précité, alimente celle-ci feuille à feuille pour éviter les copies mal centrées.
