PROBLEM TO BE SOLVED: To permit necessary operation for work to maintenance workers, but make it possible to also prevent flowing out of information which requires confidentiality, by the maintenance workers. SOLUTION: When machine users are specified as customer engineers by authentication at the beginning of using (login time) (step S102; Yes), a system control unit 7 displays operation items not permitted to the customer engineers, making distinction from operation items permitted, for example, by making half luminance display in an indication operation display unit 6 (step S103). It is possible to set the permitted operation items by a user who is registered to have a manager's authority beforehand. COPYRIGHT: (C)2006,JPO&NCIPI
