PROBLEM TO BE SOLVED: To speedify motion before drilling work (teaching movement to put a mark for correction of a work in a view field of a camera forθcorrection) and to improve drilling efficiency. SOLUTION: This device is constituted by arranging two cameras 4 forθcorrection at an upper position except for upper positions of a drilling part 3 and a moving mechanism 2 free to adjust positions on the same straight line of an X axis. Thereafter, a data for correction in theθdirection of a drilling objective work 100 is automatically and highly speedily provided only by moving them with a teaching data input immediately below the two cameras 4, 4 forθcorrection previously positionally adjusted with an interval of the marks 100a, 100a for correction.
