PROBLEM TO BE SOLVED: To provide a split scan type cathode-ray tube device which reduces the circuit scale and the production cost and is easily adjusted. SOLUTION: Electron guns which divide a phosphor screen into two scan area to scan them with electron beams are arranged in two necks of a vacuum housing. Individual deflecting devices 26 which deflect the electron beams are provided around necks. A deflecting output circuit 32 is provided with two individual field deflecting output circuits 34a and 34b which individually drive individual field deflecting parts 26a of two individual deflecting devices 26 and a common line deflecting circuit 35 which drives two individual line deflecting parts 26b of individual deflecting devices. |
