<p>PROBLEM TO BE SOLVED: To obtain a movement apparatus by which a diagonal brace can be detected in the slight interval between pieces of furnature by a configuration wherein the movement of a pulley holder is combined properly with the rotation of a pulley attached to the holder and a sensor holder can be scanned freely. SOLUTION: A pulley holder 1 provided with a pulley 19 which is slid to the up-and-down direction and which is freely rotatable is attached to a guide rod 5. A sensor holder 8 which is slid to the right and left directions is installed at a sensor guide pipe 6, and a diagonal-brace detection sensor is mounted on the sensor holder 8. In a state that the pulley holder 7 is fixed to the rod 5, the pulley 19 is turned. Then, a string which is wound on a guide roller 14 is wound, and the sensor holder 8 is moved to the left or the right with reference to the pipe 6. The rotation of the pulley 19 is stopped, and the pulley holder 7 is moved upward or downward. Then, the sensor holder 8 is moved downward or upward due to the movement of the pipe 6 due to the movement of the string. Consequently, when the movement of the pulley holder 7 is combined with the rotation of the pulley 19, the sensor holder 8 can be scanned freely.</p> |
