PURPOSE:To improve a landing characteristic by applying a waveform shaping to an input signal, applying it to an arithmetic/amplification part that has a amplifying function and taking out correcting current running to one direction. CONSTITUTION:An upper/lower part and left/right side bobbin winding deflection correcting means 9 is provided on the surface of the reaward side of a reaward emlargement part 3a in a bobbin 3 which consists of a deflecting yoke 1. The upper/ lower part and left/right side bobbin winding deflection correcting means 9 consists of a circle mounting plate 10, upper/lower bobbin deflection correcting coil 12 and 13 which are installed on the left and the right sides putting a center hole 11 that is formed at the center of the mounting plate between, and left/right side bobbin deflection correcting coil 14 and 15 which are installed on, with crossing perpendicularly, the upper and lower parts putting the center hole 11 between as is the same on the above. And the upper/lower and left/right bobbin deflection correcting means 9 is equipped firmly with the deflecting yoke 1 by installing the mounting plate 10 to the surface of the reaward side of the reaward enlargement part 3a in the bobbin 3. Thereby, the degree of the free layout of a deflecting magnetic field is increased and along with a distortion correction, the improvement of a landing characteristic and convergence characteristic etc. are realized in high qualities.
