どで、システムが大型化してしまう恐れがある。Generally, in order to prevent color shift and display movement caused by DC magnetic fields applied externally to CRTs, the front surface is made of a high permeability magnetic material and is open, due to the nature of CRTs whose front surface is the display surface. As described in Japanese Patent Application Laid-open No. 63208386,
The above-mentioned shield box is combined with a coil only in the front direction, and is only used as a countermeasure against magnetic fields from all directions. However, with the shield box made of high permeability magnetic + IE material and with an open front side, shield box
If the outside magnetic field is also collected, it may become a leakage magnetic field and affect the CRT inside the shield box.・There is a risk that the system will become larger due to coils, etc.

る。The purpose of the present invention is to prevent the seal made of a high permeability magnetic material from attracting much of the magnetic field outside the shield 130
The second purpose is to reduce the leakage magnetic field that enters the inside of the shield box by increasing the size of the shield box. This can be achieved by combining and attaching a shield box made by Kinarashi, which does not have high magnetic permeability, and installing a CRT inside it.

Without attracting much of the flowing magnetic field, the shield box made of high permeability magnetic material inside absorbs the leaking magnetic field and releases it to the opposite side, allowing the CRT inside the double shield box to
It is possible to reduce color shift and display movement by reducing the amount of magnetic field that reaches the area.

させることができる。In the upper figure, a CRT2 is covered with a double shield BOX consisting of a shield BOXI made of a high permeability magnetic material and a shield BOX3 made of a metal with relatively low magnetic permeability surrounding it with a small gap. This is a cross-sectional view showing the appearance of magnetic lines of force when a magnetic field is applied to an object. The dotted lines show the lines of magnetic force when the outer metal shield 30X, which has relatively low magnetic permeability, is removed. In a double shield box, the outer shield box is made of a metal with relatively low magnetic permeability.
Seal 1 < r > ○ C inside the double shield box
The leakage magnetic field reaching RT can be reduced. According to this embodiment, color shift and display movement of the CRT can be reduced.
