A workpiece feeder includes a forward stage that separates base plates from one another and adjusts the base plates into correct top-bottom orientation and a pickup unit that individually holds the separated and adjusted base plates and horizontally aligns the held base plate into correct planar posture while feeding the held base plate to a destination. The forward stage includes a stage body that has a stage surface on which the base plates are placed and is movably supported so as to shift the stage surface and a drive unit that applies separate impacts to the stage body so that the stage body moves to apply a bouncing force and a shifting force orthogonal to the bouncing force due to the separate impacts to the base plates.

A bearing vibration measuring apparatus is an apparatus of measuring vibration of a bearing. The bearing vibration measuring apparatus detects a vibration component generated from the bearing in a state of pressing one of an inner ring and an outer ring of the bearing in an axial direction while relatively rotating other of the inner ring and the outer ring to detect a defect of the bearing based on the vibration component. The bearing vibration measuring apparatus includes a driving mechanism elongated and contracted for inclining the inner ring or the outer ring.
