DRIVE TRANSMISSION DEVICE AND FEEDING DEVICE

PROBLEM TO BE SOLVED: To provide a drive transmission device, capable of performing release of drive and transmission of reverse rotational drive for a fixed time using not an expensive component but a drive source and a planetary gear mechanism, and a feeding device provided with the same. SOLUTION: The device includes: a sun gear driven by a drive source; a planetary gear; a support member which supports the planetary gear so as to be rotatable and to be revolvable around the sun gear while being meshed with the sun gear; a driven gear which revolves by first directional rotation of the sun gear, and meshes with the planetary gear when the planetary gear is moved to a predetermined position; and a rotating force imparting means which imparts a rotating force to the driven gear in a direction of rotating the sun gear in a second direction opposite to the first direction through the planetary gear. When the sun gear is rotated in the second direction, the rotating force imparting means rotates the planetary gear, whereby the revolution of the planetary gear is arrested.
