Abstract

PURPOSE: To reduce the lessening of a raster pitch and to reduce the damage of a cathode-ray tube by keeping brightness constant while changing a picture, reproduced on a screen, in size.
CONSTITUTION: Horizontal deflecting circuit 5 of a projection cathode-ray tube which reproduces and projects a picture on the screen is provided with relay switches 7a and 7b that connect horizontal width correcting coils 6a and 6b to deflecting yokes 5b∼5d, and relay switches 7c and 7d that connect impedance correcting coils 6c and 6d width coil 5e. Further, vertical oscillating circuit 8 is proviced with vertical width adjusting volume units 8b∼8d, and circuit 20 supplying beam current to the cathode-ray tube is also provided with contrast adjusting resistances 24 and 25. Then, switches 7a∼7d, volume units 8b∼8d, and resistances 24 and 25 are changed over via interlocking switches 10∼15 to change in size and project the reproduced picture on the screen and the brightness is held constant to reduce rasters and also to reduce the damage of the cathode-ray tube.
