Abstract: A process for the diazo-type multicolor reproduction according to which it is possible to obtain multi-colored copies in which portions corresponding to predetermined portions of an original are colored selectively in different hues without substantial mingling of colors, by conducting the heat transfer at relatively low temperatures (for instance, at 60*-80*C.), and a color former to be used in such process, which comprises a thermosublimative coupler and a thermosublimative, organic, solid transfer promotor having no coupling property in itself.

Abstract: A novel photosensitive plate which has a sensitivity regardless of the polarity of the applied charge is disclosed. Said photosensitive plate comprises (a) an electroconductive substrate, (b) a first inorganic photoconductive layer formed on said substrate, (c) a substantially transparent, organic insulating layer formed on said first inorganic photoconductive layer and (d) a second inorganic photoconductive layer formed on said organic insulating layer. Said photosensitive plate is characterized in that the first inorganic photoconductive layer is identical with the second photoconductive layer with respect to the type of the photoconductive material used, namely the Ntype or P-type, and when the inorganic photoconductive layers are of the N-type, the organic insulating layer is composed of an organic insulating material having a long range for electrons and when the inorganic photoconductive layers are of the P-type, the organic insulating layer is composed an organic insulating material having a long range for positive holes.

Abstract: A copying machine comprising an original detecting member upstream of an original-exposing section and a sensitive paper detecting member upstream of a sensitive paper-exposiing section in order to cause both an original and sensitive paper to reach the exposing sections synchronously. The machine also includes a mechanism whereby either the original or the sensitive paper which reaches the detecting member earlier is stopped there temporarily, and when the other late-coming original or sensitive paper has reached the detecting member, the advance of the earlier-reaching original or sensitive paper is resumed.

Abstract: A copying machine specially adapted to cause both an original and a sensitive paper to reach their respective exposing sections synchronously. The machine then cuts the sensitive paper to the same length as the original. The machine includes first and second original detecting members respectively located immediately upstream of, and at an upstream end of, the original exposing section alongside a passageway for transferring the original, a synchronously transferring roller immediately upstream of said first original detecting member, and a sensitive paper detecting member provided immediately upstream of a sensitive paper exposing section alongside a passageway for transferring the sensitive paper. The supply of sensitive paper is started when the leading edge of the original has reached the second original detecting member and the sensitive paper is cut when the rear edge of the original passes the first original detecting member. The synchronously transferring roller stops rotating when the leading edge of the original has reached the first original detecting member and resumes rotating when the leading edge of the sensitive paper has reached the sensitive paper detecting member.
