ABSTRACT:
In bonding machines such as a wire bonding machine, a lock which makes the changing of bonding data impossible is placed on specific data setting mode items, which are stored in a memory, via a data setting mode locking circuit. The changing of data in such locked data setting modes is made possible only if a password inputted is the same as a previously set-in password.
