A VDT operation monitoring apparatus for putting a VDT in a rest state when a preset operating time passes, with which an operator can select "start operation", "continue operation" or "stop operation" while the operating time is being measured. This allows a flexible action to be taken when the operator is replaced or when the operating time is to be changed.
