In a unit for a cutting apparatus, a first shaft, a second shaft, first blades and second blades individually have conductivity. A detection means includes a power source, a first wiring, a second wiring, a plurality of light emitting devices, a third wiring, and a fourth wiring. The first wiring electrically connects the first shaft and the power source. The second wiring electrically connects the second shaft and the power source. The plurality of light emitting devices are respectively attached to a plurality of holders. The third wiring electrically connects each of the plurality of light emitting devices and the first shaft. The fourth wiring electrically connects the plurality of light emitting devices and a plurality of the first blades respectively.

The present specification relates to an embodiment of an electrode material winding apparatus, in which an electrode material is processed so that an electrode tab is not disposed in an impregnation region into which an electrolyte can be injected, and the electrode material is wound so that the electrode tab is arranged only in a specific region excluding the impregnation region, thereby winding the electrode material such that the electrolyte is injected through the impregnation region.

A rotary storage device includes a body and a transfer material. The transfer material includes a first end coupled to the body, a second end opposite the first end, and a transfer material length between the first end and the second end. The transfer material length is wound around the body for an entirety of the transfer material length. The rotary storage device also includes a plurality of manufactured items disposed in a singulated manner along the transfer material length. Each of the plurality of manufactured items is removable from the transfer material.

According to an example, a method comprises unwinding a print media from an input roller toward a printing station. The printed print media is wound onto an output roller. The printed print media is unwound from the output roller toward the printing station.

A web conveying device includes a roller portion, a first air passage, a second air passage, and an air current generation portion. The roller portion rotates in contact with a web. The first air passage extends in an axial direction of a rotation shaft of the roller portion inside an outer peripheral portion of the roller portion and communicates with an outside at an end on a side of a first direction parallel to the axial direction. The second air passage extends from the first air passage in a direction that forms an obtuse angle with respect to the first direction and communicates with the outside of the outer peripheral portion. The air current generation portion generates an air current that flows in the first air passage in the first direction.
