摘要： A winding core member of a winding core is divided along an axial direction into a first main body, a second main body and a third main body. Projections which are formed at the respective main bodies can fit into cam grooves of cams provided in the winding core member. For this reason, when the cams are rotated, inner peripheral walls of the cam grooves are engaged with the projections, and the main bodies are pulled in inwardly in a radial direction so as to approach each other, so that an outer diameter of the winding core is decreased. Therefore, after a sheet material is or sheet materials are wound in layers around an outer periphery of the winding core, the winding core can be pulled out from the sheet material(s) easily.

摘要： An ink jet printer feeds a sheet of recording medium onto a platen, and record an image by ejecting droplets of ink from a print head attached to the platen. The ink jet printer has a media deforming section for deforming a part of the recording medium into a downward projection. The media deforming section includes a wedge above a recording media feeding path, and a wedge receiver below the feeding path to fit with the wedge. The wedge and the wedge receiver are joined together to press the recording medium from above and below, and form the downward projection. While the recording medium passes the platen, the downward projection wipes off ink stain on ribs of the platen.
