Abstract

PURPOSE:To obtain stable regenerated pictures, by synchronizing driving signals of the arm feeding motor to vertical synchronizing signals and by terminating motor driving within the period of vertical blanking. CONSTITUTION:Vertical synchronizing signals are separated by giving regenerated signals obtained from a pickup 2 to a vertical synchronizing separator circuit 20. This signal is divided at a dividig circuit 13. Then, an optional divided output of the dividing circuit 13 is used as a driving signal to be used when a feeding motor 8 of an arm 5 is started. Therefore, this driving signal is synchronized to the vertical synchronizing signal, and the motor 8 is always stated from the vertical synchronizing signal. On the other hand, the divided output of the dividing circuit 13 is input into a time constant circuit 21 where the pulse width of the driving pulse is set to a range so that the width may be set within the period of the vertical blanking. In this way, any flickers generated by the ripple of the power source will not appear on the regenerated picture and stable pictures is obtained.
