PURPOSE:To surely perform a disk loading operation, by fixing a pair of disk guide members to a wire in such a way that they move in different directions which are opposite to each other in accordance with the rotation of a pulley. CONSTITUTION:Each of disk guide members 4 and 4' is movably tied to each of guide bars 5 and 5' through three rolling wheels 6, respectively, and installed on supporting tables 8 and 8' which are driven by a motor 7. The motor 7 is controlled its driving by a controlling circuit and drives a pulley 10 through a transmitting means 9 composed of a combination of gears, etc. The pulley 10 is installed to a point adjuacent to the end of one of the guide bars 5 and 5', and a wire, to which a tension is given by a spring 12, is stretched between the pulley 10 and the 2nd pulley installed to a point adjacent to the end of the other guide bar. The supporting tables 8 and 8' are connected with the upper side and the lower side of the wire 13 through connecting members, respectively. |
