PURPOSE:To prevent secrecy from being leaked by starting a display stop flag when an operator leaves a terminal equipment for a fixed time to stop the display of a display part. CONSTITUTION:When the operator leaves the desk, an identification (ID) signal from an ID card carried in a breast pocket or the like can not be received and a timer 9 starts count-up operation. Receiving the count-up of the timer 9, a control part 5 sets up a display stop flag 10, and at the time of setting up the flag 10, an AND gate is closed and a picture on a CRT display part 10 disappears. When the operator returns to the desk, the ID information from the ID card 2 can be received again, so that a picture is displayed on the display part 17 and the operator can restart operation immediately after taking the seat without executing any additional operation. Consequently, the secrecy of screen information can be prevented from being leaked. |
