PROBLEM TO BE SOLVED: To eliminate or minimize exchanging of position correcting reference pin so as to reduce the production loss due to exchanging time of the reference pin, even when a printed board needs many kinds of reference hole diameters for correcting position. SOLUTION: Two kinds of reference pins for different diameters are raised by a cylinder 10 and they are inserted into a reference hole 3 for correcting position of a printed board 2. At this time, an inner pin 11 with axial diameter A is inserted thereinto to correct the position, while an outer pin 12 with axial diameter is not inserted and a force generating by the cylinder 10 is absorbed by a spring 13. When the printed board is fixed for position correction by using a built-in pin having such a structure, exchanging of reference pin for correcting position can be eliminated or minimized as necessary at every time when the hole diameter for correcting position is changed, even when the printed board needs a number of reference hole diameters for correcting position. |
