PURPOSE:To suppress the fatigue of operator's eyes and to easily execute health management by automatically counting a fixed time and informing the arrivals of a rest period. CONSTITUTION:A counting means 2 starts to count up clock signals outputted from a clock generating means 1 simultaneously with the start of operation of a document editing means 6, and after the lapse of 55 minutes, an interruption signal is outputted. A control device 3 receiving the interruption signal allows a display means 4 to display contents expressing a rest period, and when an operator retains an answer indicating no understanding, starts to count up one minute. After the lapse of one minute, a message indicating the arrival of the rest period is displayed again on the means 4. When the operator returns an answer indicating understanding, the device 3 stores a document in editing and its editing status in a storage means 5, switches the display of the means 4 to a resting picture, and when a count value reaches 5 minutes, allows the means 6 to read out the document and its editing status from the means 5, displays a message indicating the restart of edition on the means 4 and simultaneously allows the means 2 to start to count up 55 minutes. |
