Abstract
In a paper feed system where a first paper feed mechanism takes out and transfers one by one a plurality of papers placed on a paper feed table in a stack and a second paper feed mechanism transfers the papers transferred by the first paper feed mechanism to an image forming section at a predetermined timing. A paper edge detector is provided between the first and second paper feed mechanisms to detect an edge of the paper, and the first paper feed mechanism is controlled to transfer the papers at a first speed and then at a second speed not higher than the first speed when the paper edge detector detects the leading edge of the paper, the second speed being determined on the basis of the timing at which the leading edge of the paper is detected.

A paper feed system comprising a first paper feed mechanism which takes out and transfers one by one a plurality of papers placed on a paper feed table in a stack and a second paper feed mechanism which transfers the papers transferred by the first paper feed mechanism to an image forming section at a predetermined timing,
- a paper edge detector being provided between the first and second paper feed mechanisms to detect an edge of the paper, and
- a paper feed control section which controls the first paper feed mechanism to transfer the papers at a first speed and then at a second speed not higher than the first speed when the paper edge detector detects the leading edge of the paper, the second speed being determined on the basis of the timing at which the leading edge of the paper is detected, and for varying the second speed according to the timing at which the leading edge of the paper is detected, such that a uniform amount of sag across substantially a length of the papers is imparted to the papers that abut the second paper feed mechanism.
