Abstract
A copying paper feeding device comprises a first and a second paper loading sections to be loaded with a stack of copying paper sheets, a first and a second paper delivery mechanism disposed respectively in the first and second paper loading sections, a first and a second paper introducing passage extending respectively from the first and second paper loading sections and terminating in a common point of junction, a paper conveying passage extending from the point of junction, a first conveyer roller pair disposed in the first paper introducing passage, and a second conveyor roller pair disposed at the point of junction or at an upstream part of the paper conveying passage. In performing a copying process, either the first or second paper delivery mechanism is selectively actuated. The first and the second conveyor roller pairs are interlocked with each other, and adapted to be started after the first or second paper delivery mechanism has been actuated. When the first paper delivery mechanism is selectively actuated, the roller pairs are started earlier by the time required to convey a copying paper from the first conveyor roller pair to the second conveyor roller pair than when t…
