Remote controller with impact sensor

摘要

A portable operation section (10) of a controller (1) has an impact sensor (13). When the controller (1) receives an impact due to a drop or the like of the portable operation section (10), the impact sensor (13) outputs an impact detection signal to a control section (21). Upon receiving this impact detection signal, the control section (21) ignores any further signal from the portable operation section (10) and thus does not use this signal for the control of the drive of a mechanism section of, for example, a machine tool or a robot.
