Abstract
A distance measuring device is to be connected to a wave transmission module to transmit a measuring wave and a wave reception module including a first wave receiver and a second wave receiver, both of which receive the measuring wave reflected from a target. In this distance measuring device, a first wave reception period in which the first wave receiver receives the measuring wave and a second wave reception period in which the second wave receiver receives the measuring wave overlap with each other on a time axis. In addition, in this distance measuring device, a time lag is provided between respective beginning times of the first and second wave reception periods. The time lag is shorter than either the first wave reception period or the second wave reception period.
