A light emitting unit 109 of cutting insents testing unit 132 for testing cutting blade state of cutting insents and a photography unit 114 is arranged opposited, and fixed on cutting cover 104. As a result of the light emitting unit 109 and the photography unit 114 is arranged opposited, therefore, peripheral shape images which enable identify cutting blade 102a of cutting insents 102 definitely are obtained even if droplets of splashing cutting water existed. Otherwise, through fixing the light emitting unit 109 and the photography unit 114 on the cutting cover 104, thereby without need of using optical fiber and wiring. In this way, a cutting device with functions of photographing for cutting blade of cutting insents, testing imperfects and abrasion gets rid restriction of ligth for photography should use optical fiber wiring, enables hold the state of the cutting insents assuredly to photograph. |
