Abstract
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.

Claim 1
Independent Claim
359 words
A copying machine comprising a passageway for transferring an original, an original exposing section located alongside the transferring passageway for exposing the original, a mechanism for transferring the original at a predetermined speed through said original exposing section, a first original detecting member provided near the upstream end of said original transferring passageway, a second original detecting member provided upstream of said original exposing section and a Transferring roller for synchronization provided between said first and second original detecting members; and a passageway for transferring a roll of sensitive paper, a sensitive paper exposing section located alongside the transferring passageway for exposing the sensitive paper, a mechanism for transferring the sensitive paper through the transferring passageway at the same speed as that of transferring the original, a sensitive paper detecting member provided upstream of said sensitive paper exposing section, a feed mechanism provided at an upstream end of said sensitive paper transferring passageway for delivering a roll of the sensitive paper, and a cutting mechanism for cutting the roll of the sensitive paper delievered by said feed mechanism, the distance between the center of said original exposing section and said first original detecting member being equal to that between the center of said sensitive paper exposing section and the position at which to cut the sensitive paper roll, the distance between the center of said original exposing section and second original detecting member being equal to that between the center of said sensitive paper exposing section and said sensitive paper detecting member, said sensitive paer feed mechanism beginning to feed the sensitive paper when the forward end of the original has reached said second original detecting member and ceasing to supply it when the rear end of the original has passed said first original detecting member, said paper cutting mechanism cutting the sensitive paper when the rear end of the original has passed the first original detecting member and said synchronization transferring roller ceasing to rotate when the forward end of the original has reached said second original detecting member and resuming its rotation when the forward end of the sensitive paper has reached said sensitive paper detecting member.
Claim 2
Dependent Claim
359 words
A copying machine comprising a passageway for transferring an original, an original exposing section located alongside the transferring passageway for exposing the original, a mechanism for transferring the original at a predetermined speed through said original exposing section, a first original detecting member provided near the upstream end of said original transferring passageway, a second original detecting member provided upstream of said original exposing section and a Transferring roller for synchronization provided between said first and second original detecting members; and a passageway for transferring a roll of sensitive paper, a sensitive paper exposing section located alongside the transferring passageway for exposing the sensitive paper, a mechanism for transferring the sensitive paper through the transferring passageway at the same speed as that of transferring the original, a sensitive paper detecting member provided upstream of said sensitive paper exposing section, a feed mechanism provided at an upstream end of said sensitive paper transferring passageway for delivering a roll of the sensitive paper, and a cutting mechanism for cutting the roll of the sensitive paper delievered by said feed mechanism, the distance between the center of said original exposing section and said first original detecting member being equal to that between the center of said sensitive paper exposing section and the position at which to cut the sensitive paper roll, the distance between the center of said original exposing section and second original detecting member being equal to that between the center of said sensitive paper exposing section and said sensitive paper detecting member, said sensitive paer feed mechanism beginning to feed the sensitive paper when the forward end of the original has reached said second original detecting member and ceasing to supply it when the rear end of the original has passed said first original detecting member, said paper cutting mechanism cutting the sensitive paper when the rear end of the original has passed the first original detecting member and said synchronization transferring roller ceasing to rotate when the forward end of the original has reached said second original detecting member and resuming its rotation when the forward end of the sensitive paper has reached said sensitive paper detecting member.
Claim 3
Dependent Claim
109 words
The electrophotographic copying machine of claim 1 which includes a plurality of driven rollers disposed alongside the original transferring passageway for transferring the original, a transfer assisting member covering said original transferring passageway and capable of being removed when a thick original is transferred, a charging mechanism along said sensitive paper transferring passageway located between the sensitive paper feeding end and the sensitive paper exposing section, a developing device provided downstream of said sensitive paper exposing section, driven rollers along the sensitive paper transferring passageway for transferring the sensitive paper, and an optical system for projecting an image on the original exposing section on the sensitive paper exposing section.
Claim 4
Dependent Claim
67 words
The copying machine of claim 1 which further includes a mechanism for selecting the use of a roll of sensitive paper and a sheet-like sensitive paper, said selecting mechanism comprising a passageway for feeding the sheet-like sensitive paper, a change-over member for opening and closing said feed passageway and means interlocking with the change-over member for rendering the sensitive paper feed mechanism and the cutting mechanism inoperative.
Claim 5
Dependent Claim
46 words
The copying machine of claim 3 wherein the distance between the original feeding end and the center of the original exposing section is equal to, or shorter than, the distance between the sheet-like sensitive paper feeding end and the center of the sensitive paper exposing section.
Claim 6
Dependent Claim
21 words
