Abstract: An electrostatic copying machine including apparatus for transporting single sheet original documents or books past an exposure station. All originals are transported and supported by a set of drive rollers along a horizontal path at the top of the machine. To transport single sheet originals a set of opposing idler rollers, each extending adjacent to the central portion of a drive roller and biased downward toward that roller, cooperates with the drive rollers. Slightly thicker materials, such as pamphlets, are placed on a rigid transparent platform having a protective light-blocking cover sheet and are driven between the drive rollers and a set of narrow idler rollers which are located adjacent to both ends of the first idler rollers and which contact the edges of the platform. For books and other still thicker originals the top panel of the machine, to which the first idler rollers are attached, is removed so that those rollers do not interfere with the transporting of the book; the book is placed on the rigid carrier as before, with the narrow edge rollers cooperating as before to transport the carrier.

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.
