JPS5963886A - Single/plural image receiving device of cathode-ray tube forming oblong image receiving surface - Google Patents

Abstract

PURPOSE:To obtain a wide picture like Chinema Scope stereoscopically by accommodating a cathode-ray tube composing an oblong screen surface forming two electron guns and an electron gun required for the formation of plural pictures in one casing. CONSTITUTION:Electron beams 3 are projected from two electron guns 2 to a fluorescent film on the screen surface 1 of the cathode-ray tube (a). The electron beams 3 pass between deflection coils 7 (71, 72) obtaining synchronizing separation (b) at an anode part 6 through the cathodes 4 and glids 5 of the electron guns 2. When the two electron guns 2 discharge electron beams 3 simultaneously, two electron beams form two pictures on the deflection coils 7. In order to obtain one picture on the screen surface 1, one electron gun 2 is actuated and current supply to a center coil 73 is stopped to erase a picture dividing line 8, so that one picture is formed on the whole area of the oblong screen surface 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cathode ray tube image receiving device having a horizontally elongated image receiving surface. Conventionally, the image receiving surface of a cathode ray tube has a rectangular shape close to a regular quadrilateral, and the image receiving surface has an inch-shaped side diagonally.

However, the image receiving surface of this size has a narrow image range, so the image orientation is limited to the limit imaging of the subject, and the image surface is missing three-dimensionally, and the conventional image surface is
There was a problem where only channel images could be displayed. According to the present invention, single or plural image reception can be achieved using a cathode ray tube having the above-mentioned drawbacks by using a horizontally elongated image receiving surface.Regarding this device, an embodiment will be described in detail with reference to the drawings in conjunction with the text below. do.

First, electron beams 8, which are cathode rays, are emitted from two electron guns 2 onto a fluorescent film on a screen surface 1 of a cathode ray tube a, as shown in FIGS. 1 to 8, which illustrate the concept of the apparatus of the present invention. The electron beam 8 is transmitted from the cathode 4 of the electron gun 2 through the grid 5 to the deflection coil 7 where it is synchronously separated in the anoid section 6.
’ to pass through. This deflection coil 7 is configured to control the directions in which the electron beams 8 are emitted to the respective divided screen surfaces 1, because when the two electron guns 2 emit the electron beams 8 at the same time, the two electron beams 8 create two images d. The course of the electron beam 8 is determined by applying current to the deflection coil 7 □ and applying a magnetic field C to the center coil 73. At that point, a magnetic field C2 is applied to the center coil 73 at the same time to create an image dividing line 8 in the center of the screen surface l.
make. 1 to obtain one image on screen surface 1
At the same time, the conduction of the center coil 73 is stopped to erase the image dividing line 8, and the deflection coil 71 is activated to emit the electron beam 8 to the entire horizontal screen surface 1.
The conduction of the deflection coil 7! A scanning electron beam 8□ is applied to the entire area of the horizontally long screen surface 1, and one image e is created over the entire area of the horizontally long screen surface 1.

According to the present invention, a cathode ray tube a forming a horizontally long screen surface forming two electron guns 2 and an electron gun 2 necessary for creating two or more plural images are housed in one casing 10. A screen surface 1 having a horizontally long surface or area necessary for these images is formed. The deflection coil 7 forms an oblique angle on the screen surface l to deflect the image into sections between each image. As mentioned above, it is well established that in the present invention, images are not limited to cinemascope-like horizontally elongated images, and images with an extremely spacious feeling can be obtained in three dimensions. . The present invention should be used not only for television, but also for radar reception, onlograph, etc. Can multiple images be received? l Being left behind can expand the scope of your influence and give you an advantage.
