PURPOSE:To carry out a correct convergence adjustment even if a standard or an using condition is changed by previously writing the correcting data according to a specification, the using condition on the respective pages of a memory and changing over the pages. CONSTITUTION:When the specification of a display screen displayed by a remote controller 4 is designated, a page address corresponding to this specification is generated from a control circuit 3. This page address is supplied to a memory 1 and the page is designated. This page address is supplied to a deflecting circuit 5. To a terminal 6, a synchronizing signal defining the timing of a scanning of the display screen is supplied. This signal is supplied to an address encoder 2, the addresses of respective adjusting points, interpolating points are generated, and supplied to the memory 1. The correcting data of a registration read from the memory 1 is supplied to a drive amplifier 9 through a D/A converter 8 and its output is supplied to a registration correcting coil 10.
