PURPOSE:To automate feed of papers coincident with an original in size, by interlocking an original feeder and a paper feeder in copying originals different in size, such as of Size B4 or A4. CONSTITUTION:When the main part 1 of a copying machine starts operation, and an orignal 5 of Size B4 is moved onto a platen glass, lights incident to sensors 7a, 7b are shaded by the original 5a, both actuated to provide detection signals to a first logical product circuit 11a, a first paper feeder 8a is actuated to feed a paper 9a of Size B4 to the main part 1 of the copying machine. When the original 5 fed is of Size B4, the sensor 7b alone is actuated, a second paper feeder 8b is actuated through a second logical product circuit 11b, the paper 9 of Size A4 is fed to the main part 1, thus permitting the paper coincident with the original in size to be automatically fed. |
