IPC: G06F15/02
Filed: 1991-12-24
Abstract: PURPOSE:To clearly perform daily health control over a VDT engaged person by detecting whether or not there is a body in front of a display part by a sensor and measuring the presence time of the body, stopping the measurement when there is no body, and generating a warning when a measurement time is up. CONSTITUTION:When the VDT engaged person operates a time setting dial 5 to set an optional time, a control part 9 makes a timer 6 to start measuring the time while confirming that the engaged person is in front of the display device with the detection signal from a sensor 10. The control part 9 confirms the detection signal of the sensor 10 at specific intervals of time, e.g. 10 seconds and when the detection signal is not inputted, it is considered that the engaged person leaves the display device, thereby making the timer 6 stop measuring the time. When the sensor detects the engaged person again, the control part 9 makes the timer restart measuring the time. When the measurement time reaches the time set with the dial 5, a warning speaker 8 and a warning display part 11 informs the engaged person of that the time is up.
