1. A workpiece supply-and-discharge device configured to supply an unmachined workpiece to a machining apparatus and to discharge a machined workpiece from the machining apparatus, the workpiece supply-and-discharge device comprising:
a bed;
a fixed portion supported on the bed;
a swivel portion configured to swivel on the bed when energized by a swivel actuator;
a plurality of fixed rails each having an arc shape and positioned to partially surround the fixed portion, the fixed rails being separated from each other;
a reciprocating actuator configured to move a movable rail having an arc shape into and out of a gap left between the fixed rails;
a guiding member included in the swivel portion; and
a workpiece gripping portion including two gripping members configured to grip the workpiece, wherein:
the workpiece gripping portion includes a slider configured to slide along the fixed rails or the movable rail, and an engagement portion engaging with the guiding member to be displaceable;
when the slider is stopped on the movable rail, the movable rail is displaced toward or away from the gap integrally with the workpiece gripping portion, and the workpiece gripping portion grips the workpiece using the gripping members or releases the workpiece;
when the movable rail is disposed in the gap, the swivel portion and the workpiece gripping portion swivel in an integrated manner to carry the workpiece;
when the workpiece gripping portion is displaced integrally with the movable rail as the movable rail enters or exits from the gap between the fixed rails, the guiding member guides the engagement portion; and
when the workpiece gripping portion swivels integrally with the swivel portion, the slider transfers from the movable rail to the fixed rails or from the fixed rails to the movable rail.
