Circuit board manufacturing apparatus with protection function for supervising/adjusting mode and method of operating the apparatus

摘要

A circuit board manufacturing apparatus and a method of operating the same include a protection function for preventing a supervising/adjusting mode to which a limited user only is accessible, from being altered where the mode is left without being logged off. The apparatus and the method include a job mode in which the manipulation is allowed to be performed by general operators who have an authority to operate the apparatus and a supervising/adjusting mode in which the manipulation is not allowed by general operators, but is allowed only to a specified user. In the case that the apparatus is placed in the supervising/adjusting mode, a protection control is executed to automatically terminate the supervising/adjusting mode when a predetermined time period expires to prevent manipulation in that mode from being performed by the general operators.
