Abstract
A sheet feeding mechanism having a pickup roller, a switch device, and a gear set is disclosed. The pickup roller drives a recording material to a first path, and the recording material proceeds from the first path to a second path or from a third path to a fourth path when the switch device is switched to a first position, and proceeds from the first path to the third path when the switch device is switched to a second position. The gear set drives the recording material from the first path to the third path when the switch device is switched to the second position and drives the recording material from the first path to the second path, from the third path to the fourth path, and from the fourth path to the first path when the switch device is switched to the first position.
