Abstract
A sheet feeding device includes a tray, a feeding member, a conveying member, a separation member, a transmission unit, and a biasing member. The separation member abuts the conveying member and separates a single sheet from sheets fed by the feeding member. The transmission unit includes first and second portions respectively having first and second transmission surfaces. Where the first and second transmission surfaces abut each other, the first portion drives the second portion that drives the feeding member. The biasing member biases either of the first and second portions so that the first and second transmission surfaces move away from each other. The conveying member is driven in a state where the separation member abuts the conveying member and the feeding member abuts the sheet stacked on the tray and is stopped. Thereafter, the first and second transmission surfaces abut each other, and the feeding member is driven.
