To provide a distance measuring device and a method that can easily measure a distance between a measuring instrument and a measurement target at low cost without having to adjust the beam to the measurement target at the time of measurement, even when the measurement target is in close proximity to another object, or when a light or radio wave from the measuring instrument is weak.SOLUTION: A measuring instrument 200 transmits an output signal to a measurement target based on a measurement start signal of a control device, and also receives a response signal from the measurement target, the measurement target 300 transmits the response signal to a measuring device in response to the output signal from the measuring instrument, and the control device 100 is wirelessly connected to the measuring instrument and the measurement target. A distance between the measuring instrument and the measurement target is measured when the measurement start signal is transmitted and when the response signal from the measurement target is received, according to a circuit delay time in the measuring instrument until the measuring device transmits an output signal in response to the measurement start signal from the control device and a circuit delay time in the measurement target until the measured object transmits a response signal in response to the output signal from the measuring instrument.SELECTED DRAWING: Figure 6 【課題】低コストでありながら計測時に測定物にビームを合わせる必要が無く、測定物が他の物体と近接している場合や、計測器からの光又は電波が微弱な場合でも、容易に計測器と測定物との測距が可能な、距離計測装置及び方法の提供。【解決手段】計測器２００は、制御装置の計測開始信号に基づき測定物に出力信号を送信すると共に測定物からの応答信号を受信し、測定物３００は、計測器からの出力信号に応じて計測装置に応答信号を送信し、制御装置１００は、無線により計測器と測定物とに接続されて、計測開始信号の出力時と測定物からの応答信号の受信時、及び、制御装置からの計測開始信号に応じて計測装置が出力信号を送信する迄の計測器における回路遅延時間、並びに、測定物が計測器からの出力信号に応じて応答信号を送信する迄の測定物における回路遅延時間に基づいて、計測器と測定物との間の距離を計測する。【選択図】図６
