FORMATION OF PHOSPHOR SCREEN AND APPARATUS THEREOF

PURPOSE:To drastically save the amount of phosphor to be used and reduce loss thereof by applying powder phosphor only to the necessary area and improve productivity by making it unnecessary to use water and resultant drying process by employing development process with air. CONSTITUTION:The panel 4 sways in the resultant direction assigned by conposing both X and Y directions, and the phosphor in the panel 4 moves in the pattern indicated by the arrow mark and adheres to the adhesive area within the panel. Swaying angle in the X direction can be varied by changing the length of link 22 and rotating radius of the arm 23, while the swaying cycle is controlled by changing the rotating speed of motor 24. Swaying angle in the Y direction can be adjusted by the normal and reverse rotation timing of motor 20, while the swaying cycle is controlled by changing the rotating speed of motor 20. The panel 4 is positioned on the panel placing board of the air developing apparatus. The drive motor drives the flat pattern nozzle for reciprocating operation and the air development can be realized in such a manner that the phosphor at the area other than the specified color pattern area is removed by blowing of clean and dry air.
