A power transmission mechanism including an operation unit, a drive source, and a gear train mechanism including a plurality of power transmission gears of which rotation centers are arranged in a staggered pattern as viewed from the axial direction. The gear train mechanism includes a first gear located most downstream in the power transmission direction, a second gear that engages with the first gear, and a dummy gear that does not have a function of transmitting power. The dummy gear engages with the first gear and has a rotation center arranged in a staggered pattern with respect to the first gear and the second gear as viewed from the axial direction.

A sheet conveyance device includes a center shaft; a driving portion and a rotatable member. The rotatable member includes an engaging hole to engage with the center shaft, a drive coupling portion disposed on an outer diameter side of the engaging hole and coupled to the driving portion, and a restricting portion disposed on the outer diameter side of the engaging hole and for restricting movement of a moving member. The rotatable member changes a position of the restricting member by being rotated between a first position and a second position rotated from the first position about the center shaft by driving of the driving portion. As viewed in an axial direction of the center shaft, a position of a center of gravity of the rotatable member is positioned in an inner diameter side of an inner diameter surface of the engaging hole.
