The present invention relates to a television with a built-in video cassette recorder, and more particularly, to a television with a built-in video cassette recorder having an improved structure of a door for opening and closing a cassette. An example of a video cassette recorder built-in television in which an image display device including a cathode ray tube and a video cassette recorder are incorporated in one case is shown as a schematic cross-sectional view in FIG. Referring to the drawings, the video cassette recorder built-in television 1 includes a cathode ray tube 3 and a video cassette recorder 4 provided inside the case 2. The casing 2 is provided with a cassette inlet 2a for inserting the cassette 6 into the video cassette recorder 4 or for ejecting the cassette 6 from the video cassette recorder 4. The door 5 for opening or closing 2a is engaged. On the other hand, as shown in the enlarged second door showing a part of the door 5 as a separate perspective view, the case 2 is formed with a pair of one finger shaft 2b facing each other and on both sides of the door 5. The formed coupling hole 5b is inserted into the hinge shaft 2b of the case 2 so that the door 5 is rotatably supported by the case 2. The door 5 installed in this way is attached to either one of the door 5 and the case 2 to maintain a closed state by an attachment force between a magnet (not shown) and a magnetic material (not shown) attached to the other side. Done. A plurality of switch knobs 5a are provided on one side of the door 5 for inputting various signals such as adjustment of a screen or sound output state, and correspond to the respective switch knobs 5a inside the door 5. A circuit board (not shown) equipped with a switch (not shown) is installed at a position where the switch knob 5a is operated so that the signal is transmitted to a main circuit board (not shown) provided in the case 2. In the conventional video cassette recorder built-in television 1 having such a configuration, in order to input a signal, the door 5 is opened and the switch knobs 5a are exposed to perform an operation, and when the operation of the switch knob 5a is completed, the door (5) is attached to close the cassette entrance 2a to protect it from foreign matter such as dust. In the case where the cassette 6 is to be inserted into the video cassette recorder 4, the door 5 is opened in the same manner as above to open the cassette entrance 2a, the cassette entrance 2a is opened, and the cassette entrance 2a is opened. The video is adapted to insert the cassette 6 into the cassette recorder 4. On the other hand, when the cassette in the video cassette recorder 4 is to be taken out, when the cassette is taken out through the cassette inlet 2a, the door 5 is opened in advance so that the ejection movement is not interfered by the door. The cassette was to be taken out with (2a) open. However, such a conventional video cassette recorder built-in television has a problem that it is cumbersome because a person needs to open a cassette door by directly opening a door when the cassette is taken out. In addition, if the cassette ejection operation is performed without opening the door, the cassette or the door may be damaged, and the cassette may be inserted into the video cassette recorder after colliding with the door. . The present invention has been made to solve the above problems, and an object of the present invention is to provide an improved video cassette recorder built-in television so that it is not necessary to manually open a door when a cassette is ejected from the video cassette recorder through the cassette entrance of the case. .

In order to achieve the above object, a video cassette recorder built-in television according to the present invention includes a video display device including a cathode ray tube and a video cassette recorder, and has a cassette entrance to allow the cassette to enter and exit the video cassette recorder. A first door rotatably installed on the case and the case, and on one side thereof, a plurality of switch knobs for signal input and a second door rotatably installed on the first door in a position facing the cassette inlet; And the second door is biased in a direction of closing the cassette entrance and is pushed by a cassette taken out from the video cassette recorder through the cassette entrance and rotated in a direction of opening the cassette entrance. . In this invention, it is preferable to form a guide rib for guiding the ejection movement of the cassette in the portion pressed by the ejected cassette of the second door. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 3 is a schematic cross-sectional view of a television with a built-in video cassette recorder according to the present invention, and FIG. 4 is a schematic separated perspective view of the door portion of the television shown in FIG. 5 and 6 are enlarged views of part “A” of FIG. 3, and FIG. 5 shows a state in which the second door is closing the cassette entrance, and FIG. 6 shows a state in which the second door is opening the cassette entrance. . Referring to the drawings, the television 10 according to the present invention includes a case 20, a cathode ray tube 30, and a video cassette recorder 40 provided inside the case 20. The case 20 is provided with a cassette inlet 21 so that the cassette 60 can be inserted into the video cassette recorder 40 or the cassette 60 can be ejected from the video cassette recorder 40. And the door 50 for opening and closing the cassette entrance 21 is coupled to the case 20, the door 50 is composed of a first door 510 and a second door (520). Coupling holes 519 are formed at both ends of the first door 510, and the first holes 510 are fitted into the hinge shafts 22 provided in the case 20. The case 20 is supported by the state which can be rotated. Coupling holes 524 are formed at both ends of the second door 520, and the coupling hole 524 is fitted with a hinge shaft 514 provided in the first door 510 to fit the second door 520. ) Is supported by the first door 510 in a rotatable state. Ring portions 512 and 522 are formed in the first door 510 and the second door 520, respectively, and both ends of the tension coil spring 530 are hooked to each of the ring portions 512 and 522. 520 is elastically biased in a direction to close the cassette entrance 21. In addition, a locking jaw 523 is formed at a lower end of the second door 520, and a stopper 513 is formed at a portion corresponding to the locking jaw 523 of the first door 510. The second door 520 rotated by the biasing force of 530 is stopped in a state in which the second door 520 is located in parallel with the first door 510. Reference numeral 521 denotes a guide rib provided to smoothly take out the tape. The state in which the door 50 is opened and closed in the video cassette recorder built-in television 10 having such a configuration is as follows. First, as shown in FIG. 5, the cassette 60 mounted in the video cassette recorder 40 with both the first door 510 and the second door 520 closed to close the cassette entrance 21. ), The cassette 60 to be ejected contacts the guide rib 521 formed to be inclined in the second door 520 and presses the second door 520. Accordingly, the second door 520 is rotated counterclockwise in the fifth door to open the cassette entrance 21 as shown in FIG. 6 and the ejection of the cassette 60 is completed. In this process, the guide rib 521 smoothly guides the ejection movement of the cassette 60, and the tension coil spring 530 is tensioned to have a restoring force. When the cassette 60 is taken out in this way, the second door 520 is rotated clockwise in the direction of closing the cassette entrance 21 again, that is, in FIG. 6 by the restoring force of the spring 530. In the middle of rotation, the second door 520 stops when the locking jaw 523 formed at the lower end thereof is caught by the stopper 513 of the first door 510, and then again opens the cassette entrance 21 as shown in FIG. By closing, it is possible to prevent foreign matter from entering into the cassette entrance 21. As described above, in the video cassette recorder built-in television 10 according to the present invention, since the cassette entrance and exit 21 is automatically opened by the cassette 60 taken out when the cassette is taken out, the conventional video cassette recorder built-in television 1 By manually opening the door 5, the hassle of opening the cassette entrance 2a can be eliminated. Meanwhile, as shown in the fifth door, the cassette is inserted into the video cassette recorder 40 with the door 50 closing the cassette entrance 21, or the image and sound output state is adjusted or other data is input. In order to operate the switch knob 511 provided on the inner surface of the first door 510, the first door 510 is rotated in the counterclockwise direction manually as in the conventional video cassette recorder built-in television 1. Let's do it. Accordingly, the first door 510 and the second door 520 rotate about the hinge shaft 22 formed in the case 20 so that the switch knob 511 is exposed to the outside as shown in FIG. The cassette entrance 21 is left open. In such a state, the desired switch knob may be pressed to input a signal or the cassette may be inserted into the video cassette recorder 40 through the cassette entrance 21. In the television 10 of the present embodiment, although the guide rib 521 is formed in the second door 520, the cassette 60 may be taken out even if the guide rib 521 is not formed. . In addition, a tension coil spring 530 having both ends fixed to the first door 510 and the second door 520 is used as a means for biasing the second door 520 in the direction in which the cassette door 21 is closed. It became. However, the present invention is not limited thereto, and for example, a torsion spring is installed coaxially to the hinge shaft 514 of the first door 510, and both ends thereof are fixed to the first door 510 and the second door 520, respectively.
