Abstract: In a filament winding apparatus, a supplying device supplies fiber bundles to a surface of a core material. A moving part is movable relative to the core material, and rotatable around a rotational axis extending in a vertical direction. A small diameter aligning guide part is placed at the moving part and has an opening portion through which the core material can pass. The small diameter aligning guide part guides fiber bundles to an outer peripheral surface of the core material such that the fiber bundles are arranged side by side in a circumferential direction of the core material. The tightening fiber bobbin supporting part is placed at the moving part and rotates around a center of the opening portion. A winding guide rotates with the tightening fiber bobbin supporting part and guides a tightening fiber bundle drawn from a tightening fiber bobbin toward the surface of the core material.

Abstract: An image recording device includes a pressing force adjusting mechanism that adjusts a pressing force of a developing roller that is provided by an elastic member, against a photoconductive drum. This provides for modification and adjustment of the pressing force of the developing roller that is pressed against the photoconductive drum by the biasing force from the elastic member. Consequently, even where the developing rollers have various radius dimensions or where elastic force of the elastic member changes, adequate pressing force depending on each case can be applied to the developing roller, thereby improving the recorded quality of the image recording device.
Abstract translation: 一种图像记录装置包括：压力调节机构，其将由弹性构件提供的显影辊的按压力抵靠感光鼓。 这提供了通过来自弹性构件的偏置力压靠在感光鼓上的显影辊的按压力的修改和调整。 因此，即使在显影辊具有各种半径尺寸或弹性构件的弹力变化的情况下，也可以对显影辊施加足够的按照每种情况的按压力，从而提高图像记录装置的记录质量。

Abstract: A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.
