Abstract: A parts arranger comprising a rotating disk (4) which has a plurality of part accommodating holes (6) for accommodating screws (5) arranged in a circumferential row or a plurality of concentric rows and is supported in a condition inclined at a predetermined angle .theta. relative to a horizontal plane, a circumference guide (7) which is disposed along an outer circumference of the rotating disk (4) so as to be substantially perpendicular to a surface of the rotating disk, and a stepping motor (1) which rotates the rotating disk (4) at a predetermined angle in a normal direction and then at a predetermined angle in a reverse direction.

Abstract: A component holder body is provided with a component arrangement section where an installation space for a component is defined, and holding parts for holding the component arranged in the installation space. The component arrangement section is constructed so as to be shiftable between a holding position in which the component arrangement section projects and a position projecting upward from the holding position. Meanwhile, the holding parts are designed so as to shift, in association with the shift of the component arrangement section between the holding and projecting positions, between a holding posture for holding the component and a retreat posture for opening the installation space.

Abstract: Various component supplying cassettes contain components of different kinds and feed predetermined numbers of the components to take-out openings of the cassettes. A tool supplying cassette contains several kinds of tools for use with the components or for use in assembling the components and selectively feeds the tools to a take-out opening of the cassette. The component and tool supplying cassettes are set in or removed from a component/tool supplying unit of an apparatus using the components and tools in accordance with operating procedures of the apparatus and the quantity of consumption of components, thereby allowing supply of necessary components and tools to the apparatus for every necessary occasion.
