Abstract

PURPOSE:To make equal the vertical deflection quantity of each pick up tube, by adjusting the branch current with the constant current circuit connectrd to the junction of the deflection coil, in the series connection of the vertical deflection coil of a TV camera. CONSTITUTION:The deflection coils 1R, 1B and 1G are in series connection, and vertical deflection current is supplied from the operational amplidier 2. The current flowing to the coil 1R is ajdusted with the current IB of the constant current circuit constituted with the current detector 17 and the operational amplifier 14. The constant current constituted with the operational amplifier 15, current detection circuit 18, operational amplifier 16, and current detection circuit 19, has reverse current IB. Thus, the adjustment of registration is made by flowing the current of ID + or - IR to the coil 1R, ID + or - IB to the coil 1G and ID to the coil 1G. Since the current is fed from the constant current circuit, the branch current of each coil can not be varied even if the junction potential is varied.
