Abstract: Helical protrusion portions are formed on a peripheral side surface face of a bobbin, and a helical element is screwed into the helical grooves formed between the helical protrusion portions. The lower end of the bobbing is screwed onto an attachment fitting provided with a first collar portion at an intermediate portion and a second collar portion at the end. The depth of the helical groove portions becomes gradually shallower toward the leading end of the helical protrusion portions, and the helical protrusion portions formed on the lower end of the bobbin are formed higher, so that the position of the helical element is stabilized. Thus, deviation of the resonance point of the helical element can be prevented.

Abstract: A disc carriage for use in a disc player is provided with a pair of surfaces coming into contact with a disc when the disc is inserted or ejected from the disc player. The pair of surfaces are other than parallel and are symmetrically disposed about a center plane oriented in the direction of loading and ejecting the disc so that only peripheral edge portions of the disc contact the pair of surfaces. A second pair of surfaces disposed opposite to the first pair of surfaces can also be arranged in a non-parallel position, symmetrically disposed about the center plane, to cooperate with the first pair of surfaces so that only peripheral edge portions of the disc contact either pair of surfaces.
