ABSTRACT:
An assembling apparatus includes a mounting table on which a printed circuit board is supported by back-up pins held on a base plate. The mounting table is movable in an X direction and a mounting head for mounting electronic parts on the printed circuit board is movable in a Y direction. A back-up pin stocker is provided in the vicinity of the base plate, which stores spare back-up pins being not used. A replacing unit is provided attached to the mounting head to be movable between the base plate and the back-up pin stocker together with the mounting head so that the back-up pins held on the base plate can be replaced with the back-up pins stored in the back-up pin stocker on the basis of data representative of the type of a printed circuit board, etc. by the replacing unit when the printed circuit board to be assembled is changed.
