PURPOSE:To simplify the attraction and release of magnetic bodies without a prime mover by arranging two magnetic bodies in the direction so that they attract to each other, holding said magnets by a pair of magnetic bodies, and pushing and pulling the upper magnet between the magnetic bodies. CONSTITUTION:Platforms 4a-4d are evenly spaced on the top surface of a bed 4. Magnetic bodies, e.g., washers 3 are placed on the platforms 4a and 4c. An attracting body comprising magnetic bodies ia and ib between which one permanent magnet 2a is held is stopped on the platform 4a, and attracts the washer 3. On the other hand, the other permanent magnets 2b are fixed on the platforms 4b and 4d. Then, the attracting body moves in the direction of an arrow A, and the upper permanent 2b on the platform 4b passes the magnetic bodies ia and ib. At this time, the permanent magnets 2a and 2b are so arranged that they attract each other. Thus the washer 3 can be released on the platform 4b from the attracting body. |
