PROBLEM TO BE SOLVED: To surely improve the degree of skill of a worker by providing an alarm means for giving an alarm when it is judged that a work is not ended within a target working time by a judgment result display means. SOLUTION: The residual time of a work is continuously alarmed to a worker by light and sound through a residual time alarm part 4 and a speaker 7 during a working time. When a target working time is passed, it is judged by a judgment result display part 4 whether a signal of work end is inputted from the worker or not. When the signal is inputted (the work is ended within the target working time), a 'GOOD' display part 5a is lighted. When no signal is inputted (the work is not ended within the target working time), an 'NG' display part 5b is lighted, and an alarm buzzer 6 is also rung. The worker can know whether the work is ended within the target working time or not by these display and alarm sound. |
