PROBLEM TO BE SOLVED: To provide a supply time-alarming device, with which time for supplying lubricant to a sliding part of a sewing machine is calculated according to the practical using condition of the sewing machine with sufficient accuracy and the lubricant can be suitably manually supplied at suitable time. SOLUTION: Standard replenishment information that relates standard use condition of an electronic sewing machine and standard replenishment time AST for supplying a sliding section when the electric sawing machine is used under the standard use condition is memorized beforehand, when actual use condition of the electronic sewing machine is detected and read (S17) every predetermined timing of every other hour (S15:Yes), correction replenishment time HCO to standard replenishment time AST is calculated by operations according to degree of actual use condition to standard use condition(S20, S21). Then, an alarm is given to prompt the replenishment (S23) every time when sewing total time of performed sewing with the electronic sewing machine reaches correction replenishment time HCO (S22:Yes).
