Abstract

PURPOSE:To project a picture fed from a CRT on a screen provided on a single inner side of a door and therefore to prevent the soils of each part to ensure projection of pictures of high quality, by distributing on a vertical in-line plural subject CRTs within a housing and providing doors to the front left and right sides of the housing respectively. CONSTITUTION:Plural projecting CRT7 are distributed on a vertical in-line within a housing 1 of a projection type TV receiver. Then doors 8 and 9 which open laterally are fixed to the front left and right sides of the housing 1 by means of hinges 13. A screen 10 is set on the inner side of the door 8, and a mirror 11 is provided to the inner side of the door 9 respectively. Thus the TV pictures given from the CRT7 are projected on the screen 10 from the mirror 11. In such a constitution, the soils or breakdown can be avoided for each part while the TV receiver is not in use. Thus pictures of high quality are projected for a long period of time. The opening of doors can be controlled by means of a rotary opening control projection piece 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called reflective front type projection television receiver.

As shown in FIG. 1, a conventional projection television receiver of this type has three projection cathode ray tubes 2, R, G, and B, arranged in-line laterally in a housing 1. Housing 1
Attach the screen 3 to the rear upper part of the housing 1.
A vertically opening door 4 was provided to cover the front and top surfaces of the door, and a mirror 5 was provided on the inner surface of the door 4. but,
With conventional devices like this, the screen 3 is located high up, making it difficult to see when sitting in a Japanese-style room, and the screen 3 remains exposed to the outside even when not in use. This had the disadvantage that it became dirty and easily damaged.

Part 7. SUMMARY OF THE INVENTION An object of the present invention is to provide a front-type projection television receiver that eliminates the above-mentioned disadvantages of the prior art.

Hereinafter, the present invention will be described in detail with reference to FIGS. 2 to 4 showing one embodiment thereof. In this receiver, first, a housing 6 with an open front is provided, and three projection cathode ray tubes 7, R, G, and H, are arranged in-line in the vertical direction inside the housing 6. Doors 8°9, which can be opened and closed horizontally, are attached to the front left and right sides of the housing 6 by connecting them with hinges or the like.

A screen 10 is provided on the inner surface of one door 8, and a mirror 11 for projecting the television image from the projection cathode ray tube 7 onto the screen 10 is provided on the inner surface of the other door 9. It is preferable that the door 9 is constructed so that the portion where the mirror 11 is provided can be further bent.

Still, the doors 8 and 9 are equipped with hinges 13 or the like integrally provided with a protrusion 12 for regulating the rotation angle, as shown in FIG. You can install it with.

With this configuration, when not in use, the door 8.9 is closed to cover the front surface of the housing 6, as shown in FIG. Then, the projection cathode ray tube 7, the screen 1o, and the mirror 11 can all be housed within the housing 6, so that they are less likely to get dirty with dust or get damaged by hitting other objects. Therefore, a good image can be displayed for a long period of time, and the service life can be extended.

However, the appearance can still be made good.

On the other hand, when in use, as shown in FIGS. 3 and 4, the doors 8 and 9 are opened laterally to a predetermined angle, and the projection cathode ray tube 7 is opened.
By reflecting the television image from a mirror 11 and projecting it onto a screen 10, a color television image is projected on a screen 1o. In this way,
The 1° screen position can be lowered much lower than before, almost to the floor, so even when sitting in a Japanese-style room, the image can be projected at about eye level, making it extremely easy to see. In addition, it is possible to obtain the best color balance at that time.

As described above, according to the present invention, a projection cathode ray tube is arranged vertically in-line in a housing, and doors are provided on the front left and right sides of the housing so that they can be opened and closed horizontally. By providing a screen on one side and a hole on the other inner surface, each part will not get dirty or damaged when not in use, and a good image can be projected for a long period of time.
It is possible to obtain a projection type television receiver that can lower the screen position and project images when in use, and is suitable for viewing while sitting in a Japanese-style room.
