A transfer mechanism includes a main rotating member, a first driving unit, a support mechanism, a holding unit, a second driving unit and control unit and transfers a sheet member from a pickup position to a delivery position. The support mechanism is connected to the main rotating member and the holding unit. The control unit controls the second driving unit in such a manner that, when the sheet member is placed in at least one of the pickup position and the delivery position, a position of the holding unit is not substantially changed in a state where the main rotating member rotates around the rotational axis in the first rotation direction.

A recording system includes a recording portion that performs recording on a medium, a stacking portion that stacks the medium recorded by the recording portion, and a processing portion that processes a bundle of media stacked on the stacking portion, in which a controller that controls feeding of the medium to the stacking portion determines a maximum number of sheets of media to be stacked on the stacking portion, based on information on swelling of the medium recorded by the recording portion.

A conveyance device includes a tray on an upper surface of the conveyance device and an upper guide below the tray. The tray receives a sheet, and the upper guide defines a conveyance path in which the sheet is conveyed. The upper guide is movable together with the tray to open the conveyance path.
