PURPOSE:To obtain a position selecting device which prevents double position selection and does not make any double piercing by writing only input which are different from already stored storage data in a data storage section when position selecting information is stored in the data storage section. CONSTITUTION:NC data 1 are read by a data input section 2 equipped with a detecting mechanism of an optical head, magnetic head, etc. Unit data outputted from the data input section 2 are inputted to a data storage section 4 through a data controlling section 3 having an interface function, but, since the data selecting means 9 of the data controlling section 3 selects the unit data inputted to the data storage section 4 one by one, unit data commanding small hole piercing at an overlapped position are not inputted to the data storage section 4. Then the data storage section 4 which stores the checked unit data only outputs a signal commanding a position at which a small hole is to be pierced to a piercing section 7 provided with a drill driving means 6 and drill controlling means 5 which controls the means 6, and thus, piercing to a printed board 8 is performed. |
