Abstract:
An ultrasonic processing device for applying an ultrasonic processing operation to a processing object, said device comprising:a plurality of vibrating elements for generating ultrasonic; and means for moving said processing object in a predetermined direction relatively with respect to said vibrating elements, wherein: regions to which said vibrating elements project ultrasonic are ultrasonic-projected regions each having a predetermined width in a width direction that is substantially orthogonal to said predetermined direction, and a whole arrangement of said plurality of vibrating elements planarly extends in said predetermined direction and in said width direction; and by moving said processing object relatively in said predetermined direction, ultrasonic-projected regions of said vibrating elements are caused to cover an ultrasonic processing target region of said processing object, so that ultrasonic should be projected to a complete entirety of said ultrasonic processing target region, wherein: said plurality of vibrating elements composes a plurality of element arrays so that each element array should include one or more vibrating elements arrayed in said width direction; and said element arrays are provided in parallel in said predetermined direction, and in those in which not less than two of said vibrating elements are arrayed, said vibrating elements are arranged so that: an element space is formed, to a predetermined width each, between adjacent vibrating elements, at a position corresponding to a non-provision region including the element space in one of said element arrays, said vibrating element composing another one of said element arrays is placed, and the width of said element space exceeds an insulation distance for insulation between said vibrating elements.
