PURPOSE:To facilitate easy handling with a simple constitution and also to improve the control efficiency for the titled controller, by using a work attachment tool which contains an outer case and an inner case that is attached with a shaft to the inside of the outer case with free independent up/down movements of the outer case and has a side carriage attached to the inside of the inner case. CONSTITUTION:An inner case 15 is attached rotatably by means of the inside edge part of an outer case 14 and a shaft 16. At the same time, a support frame 20 is fixed at the inside of the case 15 to support the terminal part of a side carriage (work) 2 of a side 1. The control pressure is applied to the outside of the case 14 in directions of arrows P, Q and R respectively. Then the azimuth, burst and cat's-eye are controlled accurately for a head 7 at the side 1. In this case, the head 7 can keep the prescribed contact pressure to a standard disk 9 even if the up/down components are produced at the case 14 since the case 15 is attached with free up/down movements. |
