    • Ribbon tension detecting means (20, 21), which are formed of a plate-like lever body (35) each, are located individually on the upstream side and the downstream side of a platen (7) with respect to its travel. The plate-like lever body (35) has first and second rollers (47, 48) on the upstream and downstream sides with respect to travel of a ribbon, and swings around an axis of rotation of the second roller (48), depending on a tension of the ribbon traveling guided by the rollers (47, 48). If the amount of its swing is not less than or not more than a fixed value, a ribbon feed motor (18) or a ribbon take-up motor (19) is driven. Further, the ribbon tension detecting means (20, 21) are provided with a smoothing member which touches the ink ribbon (13) to remove wrinkles from the ink ribbon (13).

    • A pair of coma aberration correction coils and a pair of YH correction coils are placed in upper and lower portions on an electron gun side from a ferrite core, and a pair of vertical auxiliary coils generating a magnetic field in the same direction as that of a vertical deflection magnetic field are placed in right and left portions on the electron gun side from the ferrite core. A horizontal deflection coil has a first coil and a second coil on an inner circumferential side of the first coil. A useful portion of the second coil is placed in a range of ±45° from a vertical axis with respect to a tube axis, and a bend portion of the second coil is placed on the electron gun side from a position that is away from the end on a screen side of the ferrite core to the screen side by 10 mm. Because of this, the misconvergence of PQH can be suppressed without increasing cost and power consumption with a simple configuration.

    • A color picture tube device has a funnel glass, a pair of horizontal deflection coils, an insulating frame, and a pair of vertical deflection coils. The pair of horizontal deflection coils are opposed to each other in a vertical direction around the outer surface of the funnel glass, and each have a window at the center. The insulating frame covers the horizontal deflection coils, resembles in shape a part of the funnel glass where the horizontal deflection coils are provided, and has openings in areas corresponding to windows of the horizontal deflection coils. The pair of vertical deflection coils are opposed to each other in a horizontal direction around the outer surface of the insulating frame, without overlapping the openings. A pair of correction coils are provided so as to be each at least partially inserted in a different one of the openings.

    • In a color CRT apparatus in which three electron beams are not superimposed on one point on the screen at a time, a time difference is applied to modulating signals corresponding to the respective electron beams to adjust phase, thus achieving convergence of images, the screen is flat, both a horizontal magnetic deflection field and a vertical magnetic deflection field have uniform magnetic field distribution, paths of both side electron beams and a path of the center electron beam of the three electron beams emitted from electron sources are approximately parallel, and the time difference applied to the modulating signals is set to be approximately constant throughout the screen. Thus, images formed of imaging spots of the three electron beams can be superimposed on the screen with high precision to be matched without causing increased cost.
    • 在其中三个电子束一次没有叠加在屏幕上的一个点上的彩色CRT装置中,对与各个电子束对应的调制信号施加时差以调整相位,从而实现图像的收敛,屏幕是 平面,水平磁偏转场和垂直磁偏转场都具有均匀的磁场分布,两侧电子束的路径和从电子源发射的三个电子束的中心电子束的路径大致平行,时间 施加到调制信号的差异被设置为在整个屏幕上大致恒定。 因此,可以以高精度将三个电子束的成像点形成的图像重叠在屏幕上,而不会增加成本。
