Abstract
A lock controller for automatically unlocking and locking a lockable part such as a vehicle door uses a detector for detecting a hand approaching inside a plurality of detection areas. Such a detector is not only arranged to transmit electromagnetic waves and to receive the reflected waves from a target object of detection such as a person's hand but also provided with a plurality of wave detection circuit parts for mixing wave detection signals corresponding to said transmission waves with signals received by said reception antenna at different sampling timings and outputting the mixed signals. A plurality of judging circuit parts each correspond to different one of the wave detection circuit parts and serve to switch on a detection output based on the outputted signals from said wave detection circuit parts to indicate that said target object is approaching and at a speed within a specified range. The detection areas have different sizes for each of the judging circuit parts corresponding to the different sampling timings of the wave detection circuit parts.
