PROBLEM TO BE SOLVED: To provide a tea leaf cutter which does not deteriorate quality of cut tea leaves, and prevents scattering of shreds, chips and the like of tea leaves cut during cutting of the tea leaves into air.SOLUTION: A tea leaf cutter 1 includes: a fixed blade holder 12 which is fixed to a base 11 and where a plurality of fixed blades serving as inner blades are mounted at predetermined intervals on the outer peripheral side so as to draw a part of a semicircle a mesh-like curved outer blade 13 which is rotatably supported by the base 11 and provided with a punching metal plate having a number of small holes and serving as an outer blade at a predetermined distance from the tips of the plurality of fixed blades and an oscillation mechanism part 16 which converts rotation movement from rotation means such as a motor 21 into reciprocating movement to oscillate the mesh-like curved outer blade 13 with respect to the base 11. Tea leaves are cut between the punching metal plate of the oscillated mesh-like curved outer blade 13 and the plurality of fixed blades mounted to the fixed blade holder 12.COPYRIGHT: (C)2014,JPO&INPIT【課題】切断された茶葉の品質が低下せず、かつ、茶葉の切断時に切断された茶葉の切れ端や切粉等が空中で飛散しないようにした茶葉切断装置を提供すること。【解決手段】茶葉切断装置1は、基台11に固定され、内刃となる複数の固定刃が半円の一部を描くように外周側に所定間隔で装着された固定刃ホルダ12と、基台11に回動可能に支持されると共に、外刃となる多数の小孔を有するパンチングメタル板が複数の固定刃の先端に対し所定の間隔を空けて設けられた網目状湾曲外刃13と、モータ21等の回転手段からの回転運動を往復運動に変換して網目状湾曲外刃13を基台に対し揺動させる揺動機構部16とを有し、揺動する網目状湾曲外刃13のパンチングメタル板と固定刃ホルダ12に装着された複数の固定刃との間で茶葉を切断する。【選択図】図8
