Abstract:
PROBLEM TO BE SOLVED: To objectively and precisely judge completion of work by furnishing a work completion information means to inform of work completion in the case when a work completion detecting means detects the work completion. SOLUTION: When a worker starts crimping work and an electric power source switch 1 is switched on, whether a value of an electric current flowing in a motor 2 input from an electric current detection circuit 6 becomes more than 14A or not is judged. When the electric current value becomes more than 14A, timing of a timer in a microcomputer 4 is started, and whether timing of this timer passes more than two seconds or not is judged. When timing of the timer is judged to pass two seconds and the electric current value rises less than 12A, a light emitting diode 8 is lighted, and it is informed to the worker that the crimping work is finished.
