<p><P>PROBLEM TO BE SOLVED: To provide a device using a small number of sensors for detecting displacement without the need for an exclusive sensor for detecting the displacement, and to provide a cutter device equipped therewith. <P>SOLUTION: The movable body displacement detecting device for a reciprocating device includes a control device for executing normal control to control a motor to reciprocate a movable body between a first position and a second position as predetermined, a limit sensor for detecting that the movable body being moved from the first position to the second position arrives at a predetermined third position beyond the second position, and an information device for giving information when the limit sensor detects it. The control device has a displacement detecting part which controls the motor to stop the operation of the information device and move the movable body being moved from the first position to the second position, close to at least the third position, and then detects the displacement of the movable body in accordance with the detection of the limit sensor. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
