Abstract

PROBLEM TO BE SOLVED: To permit disassembly in a short time and to disassemble a casing into respective parts by providing a display means for displaying a cutting position on a front panel while being composed of division into the front panel and a rear cover. SOLUTION: A front panel 2 is constituted by providing an opening part 2a sized corresponding to the display screen of a CRT, boss 2b for holding the CRT, and step part 2c showing the cutting position to be used at the time of disassembly work. When disassembling the casing of a color television receiver provided with such a front panel 2, a cutting machine tool (such as a saw, for example), is fitted to the step part 2c of the front panel 2 and with this step part 2c as a guide, the casing is cut over all the circumference. Thus, by providing the front panel 2 with the step part 2c showing the cutting position, it is not necessary to confirm a safe position at the time of disassembly work and only by fitting the cutting machine tool to the step part 2c and cutting the casing, it can be easily disassembled into the respective parts of the CRT, chassis and rear cover.

[0002]

2. Description of the Related Art FIG. 4 is an exploded perspective view showing a housing structure of a conventional color television receiver. In the figure, reference numeral 1 denotes a cathode ray tube (hereinafter, referred to as CRT) for displaying an image, and 2
Reference numeral denotes a front panel for holding the CRT 1, comprising an opening 2 a having a size corresponding to the display surface of the CRT 1 and a boss 2 b for holding the CRT 1. Reference numeral 3 denotes a chassis attached to the front panel 2, and a signal input / output terminal plate 30a
And a board 30 provided with electric components such as a heat radiating plate 30b, and a frame 31 holding the board 30.
Reference numeral 4 denotes a rear cover that covers the CRT 1 and the chassis 3, and includes a handle 4a, a connection hole 4b of a power cord (not shown), a connection hole 4c of the input / output terminal plate 30a, and a mounting hole 4d to be attached to the front panel 2. And an engagement tongue piece 4e with the front panel 2. 5 is a boss 2 on the front panel 2 for the CRT 1
Reference numeral 6 denotes a fixing screw for fixing the rear cover 4 to the front panel 2.

[0003] Next, an assembling procedure in the housing structure of the color television receiver thus configured will be described. The CRT 1 is mounted on the boss 2 b of the front panel 2 and is attached to the front panel 2 with the fixing screw 5. Thereafter, the chassis 3 composed of the frame 31 holding the substrate 30 is inserted into and attached to a rib (not shown) of the front panel 2. Next, the engaging tongue piece 4e of the rear cover 4
Is inserted into the front panel 2 while being engaged with the front panel 2. After assembling, it is fastened and fixed to a boss (not shown) of the front panel 2 with a fixing screw 6 to form a casing of the color television receiver.

At the time of disassembly, the reverse operation of the above-mentioned assembling procedure is carried out, and the rear cover 4, the chassis 3, the CR
T1 and the front panel 2 so that the fixing screws 5,
6 was disassembled into individual parts.

Further, in order to improve the efficiency of dismantling work,
Cut either the front panel 2 or the rear cover 4,
The CRT 1, the chassis 3, the front panel 2, and the rear cover 4 were disassembled.

[0006]

Since the housing structure of such a conventional color television receiver is disassembled by the above-described procedure, a plurality of fixing screws 5, 6 are sequentially removed, and the rear cover is removed. 4, the work time efficiency is considerably poor because it is disassembled into individual parts of the chassis 3, the CRT 1 and the front panel 2. Further, in the case of dismantling by a cutting operation, there is a problem that the disassembling operator has to perform a cutting operation while confirming a safe cutting position, which makes the operation difficult.

[0007] The present invention has been made to solve the above-mentioned problems, and can be dismantled in a short time.
An object of the present invention is to provide a color television receiver housing structure which can be disassembled into individual parts, can easily recognize a safe cutting position, and can be easily recycled.

[0008]

A housing structure of a color television receiver according to the present invention comprises a front panel formed of a front panel and a rear cover, and a display means for indicating a cutting position. It is.

Further, the display means has a stepped shape.

Further, the display means is formed in a groove shape.

Still further, the display means is indicated by an arrow mark.
