An apparatus may comprise a curved surface; a fluid outlet disposed to cause a fluid to move adjacent the curved surface; a sensor configured to detect a material disposed adjacent the curved surface; and a clamp configured to actuate based on detection, via the sensor, of a material disposed adjacent the curved surface, wherein the clamp is further configured to secure the material to the curved surface upon activation.

A medium processing apparatus includes a printer, a supporting member having a sheet-like shape and configured to support a discharged medium, and a winding unit configured to wind the supporting member and move with respect to the printer. The winding unit has a first case and a second case that rotatably support a winding shaft, and a placement portion placed at a flat surface. The first case and the second case in a state where axis lines of respective bearing portions that support the winding shaft are aligned with each other and in a state of being held so as to be mutually non-rotatable in a plane orthogonal to an axis line of the winding shaft, and when the winding unit is installed on a flat surface, the placement portion contacts the flat surface.

An automated filament exchange method includes: locating the spool for winding the first filament for the 3D printer; winding the first filament on the subspace of the spool located at the spool location step; allowing the first filament wound at the subspace first filament winding step to pass through a gap formed on the main space flange located between the main space and the subspace; and winding the first filament located at the main space of the spool on the main space of the spool, wherein after the first filament is wound on the subspace of the spool, the first filament passes through the gap and is then wound multi-layeredly on the main space of the spool.

An endless conveyer belt is stretched between drive and idle rollers. A carriage is arranged so as to reciprocate along the endless conveyer belt. A suction box is arranged between upper and lower belt portions of the endless conveyer belt and fixed to the carriage. A stopper plate is fixed to the carriage and extends across a conveyer surface and upward from the conveyer surface. A conveyance roller pair is arranged at the upstream end of the conveyer surface. A region of the conveyer surface from a stopper plate to the upstream end u forms a sheet accumulation area. A cover sheet covers a region upstream of the suction box in the sheet accumulation area. The cover sheet is subjected to tension in the longitudinal direction by a winding-type constant force plate spring and continually tensed spaced apart from the endless conveyer belt.

A processing device includes a processing unit and a medium accommodation portion, and the medium accommodation portion includes a flexible sheet-like accommodation member, a pivot shaft to which one end of the accommodation member is coupled, an operation portion to which the other end of the accommodation member is coupled and that is provided separably from the pivot shaft, and a pair of support portions that supports both ends of the operation portion, and the accommodation member is wound around the pivot shaft and stored inside the housing when the operation portion approaches the pivot shaft, and is unwound from the pivot shaft and hung down to accommodate the medium when the operation portion is separated from the pivot shaft, and holds a weight closer to the other end than to an intermediate position between the one end and the other end in the advance and retreat direction.
