Abstract
PURPOSE:To eliminate the problem of back-lash generated when the screw driving mechanism is employed by applying pulse if quantity required for the object to reach directly the moving position to the pulse motor. CONSTITUTION:The position signal of the spectral crystal 7 to be moved is obtained from the signal indicating portion 1 and the holding signal for indicating the present position is obtained from the signal holding portion 2. The moving distance is operated in the moving distance operating portion 8, the signal for indicating the moving distance and the direction thereof is fed to the pulse vector determination portion 9 to generate the moving distance signal and the direction signal, and to feed these signals to the acceleration start point detection portion 10 and to the retardation start point detecting portion 11 and to the back-lash eliminating portion 12. In the pulse generating portion 15, in accordance with the moving distance signal, the direction signal and the output signal of the pulse generating interval control portion 13, the pulse for smooth oprtation is generated and the object is moved by the driving portion 6 through the pulse motor 5.
