Abstract: A transmission member configured to transmit driving of a driving member to a driven member includes a first engaging portion for engaging with the driving member and a spring portion having a shape wound around an axis. The spring portion is to be compressed in a direction of the axis. The spring portion includes a first wound portion wound around the axis and a second wound portion wound around the axis. The second wound portion is connected to the first wound portion and includes a small-radius portion. The small-radius portion is disposed such that, when the spring portion is projected in the direction of the axis, an outer portion of the small-radius portion is projected to inside of a mid-portion between an outer portion of the first wound portion and an inner portion of the first wound portion in a direction perpendicular to the axis.

Abstract: A stacking device includes a stacking unit, a regulation member, an interlocking member, a pivoting member provided on the interlocking member, a sensor having an output, and a determination unit. The stacking unit stacks a sheet on the stacking unit. The regulation member moves in a first direction and a second direction opposite to the first direction and regulates a position of the sheet by abutting on an edge of the sheet stacked in the stacking unit. The interlocking member interlocks with the regulation member. The pivoting member rotates. The sensor output changes based on positions of the interlocking member and the pivoting member. The determination unit determines a size of the sheet based on the output of the sensor.
