RECIPROCATING-CYCLE MEASURING APPARATUS

PROBLEM TO BE SOLVED: To provide a reciprocating-cycle measuring apparatus by which the reciprocating cycle of a back-and-forth moved measuring object can be measured precisely and easily and by which a measurement can be automated. SOLUTION: The reciprocating-cycle measuring apparatus is provided with a signal processing means wherein, when pulse signals generated by a pulse generation means are continuously input, two continuous pluse signals are combined to form one cycle, a high-level signal in a pulse width from the rise of a first input pulse signal up to the rise of a second pulse signal is output, a low-level signal is output in remaining widths and this operation repeated in each cycle after that and a cycle measuring means which measures a reciprocating cycle.
