The system for support and movement of a stack of interfolded sheets during production of stacks of interfolded sheets in an interfolding machine comprises: at least a support table supporting a stack of interfolded sheets under formation; a conveyor belt transporting the formed stack towards a work station. The support table is movable from a first raised position to a second raised position to allow formation of a complete stack of interfolded sheets and, after the stack of interfolded sheets has been completed at the desired height, is movable towards the conveyor belt to deposit the stack thereon. Translating means for vertically translating the conveyor belt and adjusting the position of the conveyor belt, and therefore the distance of the conveyor belt, with respect to the second raised position into which the support table is brought for the completion of the formation of the stack of interfolded sheets.

A recording medium conveying device includes an endless belt to convey a recording medium, a plurality of support rollers around which the belt is wound, to rotate the belt, and a cleaner in contact with the belt to clean the belt. One of the plurality of support rollers is a separation support roller, mounted on a tiltable rotary shaft, to separate the recording medium from the belt using a curvature of the separation support roller. The separation support roller includes a contact member to contact an edge of the belt when the belt laterally moves toward one side of the belt.

A drying device (120) includes a liftable and lowerable conveying unit (40) which conveys a sheet on which ink is ejected, along a conveyance path (34); a liftable and lowerable drying unit (50) which faces the conveyance path (34) and dries the ink by heat; a lifting and lowering mechanism (60) capable of lowering a lower unit, which is a unit provided below among the conveying unit (40) and the drying unit (50), by gravity acting on the lower unit and lifting an upper unit, which is a unit provided above among the conveying unit (40) and the drying unit (50), to open the conveyance path (34); and a restriction mechanism (70) which restricts a lowering of the lower unit.

Provided is the sheet bundle transport apparatus including: an abutment unit that performs switching between an abutment state at a predetermined position and a non-abutment state; first and second press units that press the sheet bundle against first and second transport units; a press switching unit that performs switching between a first press state where the first and second press units press the sheet bundle in a predetermined region located upstream from the predetermined position in the transport direction and a second press state where the first press unit does not press the sheet bundle in the predetermined region; and a control unit that controls the abutment unit and the press switching unit to switch the non-abutment state to the abutment state and switch the first press state to the second press state so as to change an angle relative to the width direction of a predetermined sheet bundle.

A sheet conveyance apparatus configured to convey a sheet includes a casing, a belt unit, an accommodating unit, a moving unit, and a rotary member. The accommodating unit and the belt unit move to a first state, a second state, and a third state. In the first state, the accommodating unit is positioned at a closed position and the belt unit is positioned at a first position to convey the sheet by a conveyance belt. In the second state, the accommodating unit is positioned at an opening position and the belt unit is positioned at the first position to open a sheet conveyance path. In the third state, the accommodating unit is positioned at the opening position and the belt unit is positioned at a second position to allow the conveyance belt to attach to and detach from the belt unit.
