Therefore, the number of parts is increased and the cost is increased. In addition, it is necessary to mount the TV mount board and the recording / reproducing apparatus mount board respectively, and further, it is necessary to connect the TV mount board and the recording / reproducing apparatus mount board via a connector or the like. It was troublesome because it was there. In order to solve the above-mentioned problem, the present invention provides a recording / reproducing apparatus in which a television circuit and a recording / reproducing circuit are mounted on the same printed wiring board so that the apparatus can be easily assembled and disassembled and the number of parts can be reduced. The purpose is to provide a built-in TV.

[0004]

[Means for Solving the Problems]

 To achieve the above object, in a television having a built-in recording / reproducing device in which a television and a recording / reproducing device are housed in the same housing, a television circuit of the television and a recording / reproducing circuit of the recording / reproducing device are provided. However, they are mounted on the same printed wiring board.

Further, guide rails for holding both ends of the printed wiring board are provided so that the printed wiring board can be attached and detached from the rear of the housing.

[0006]

[Action]

 Insert the printed wiring board into the guide rail from the rear side of the housing and place the printed wiring board inside the housing.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing an embodiment of the present invention. In the drawing, reference numeral 1 denotes a housing of the present apparatus, in which a rectangular shaped brown tube window 2 is provided substantially in the center of the front surface of the housing 1, and a speaker window 3 is provided below the housing 1. A plurality of the speaker windows 3 may be provided on the side surface or the top surface of the housing 1.

A mechanical deck guide 4 formed integrally with the front panel 1b of the housing 1 is arranged parallel to the bottom plate 1a, and the mechanical deck 5 of the recording apparatus is fitted into the mechanical deck guide 4. Here, the mechanical deck guide 4 may be fixed to the front panel 1b of the housing 1. A guide rail 7 is provided below the mechanical deck guide 4 to hold a printed wiring board 6 on which a television circuit A and a recording / reproducing circuit B are mounted with a predetermined gap from the bottom plate 1a of the housing 1. . Both ends of the printed wiring board 6 are fitted into the grooves of the guide rail 7 from the rear side of the housing 1, and the printed wiring board 6 is fixed by sliding the printed wiring board 6 to the tip of the guide rail 7.

Next, the circuit configuration of the printed wiring board 6 of the present invention will be described with reference to FIG. In the figure, the television circuit A is mainly composed of a tuner section 10, a video amplification section 12, an audio amplification section 24 and a power supply 19. In the present invention, the tuner unit 10 is provided with a tuner for audio multiplexing, and is configured to be capable of reproducing sub-audio or stereo broadcasting. The output of the tuner section 10 is led to the video amplification section 12 via the changeover switch 11 so that an image can be displayed on the cathode ray tube 13. The output signal of the tuner section 10 is guided to the audio amplification section 14 to drive the speaker 15.

The recording / reproducing circuit B 1 of the video tape recorder 17 is mounted on the printed wiring board 6. Here, as the recording / reproducing circuit, the recording / reproducing circuit of the magneto-optical disk device may be used. The input side of the video tape recorder 17 is connected to the output terminal of the tuner section 10 via the changeover switch 16, and the reproduction output signal of the video tape recorder 17 is inputted to the video amplification section 12 via the changeover switch 11. Is configured. Reference numeral 19 is a power supply, and the power supply 19 supplies a required voltage to the tuner unit 10, the video amplification unit 12, the audio amplification unit 14, and the video tape recorder 17.

In the apparatus of the present invention thus constructed, when the terminals 16b and 16c of the changeover switch 16 are connected, the video tape recorder 17 can record the broadcast being received. Further, when the terminals 11b and 11c of the changeover switch 11 are connected, the reproduction output signal of the video tape recorder 17 is guided to the image amplification section 12, and the signal reproduced by the video tape recorder 17 can be seen through the cathode ray tube 13. . Reference numeral 18 is an external signal input terminal for the video tape recorder 17, and 17a is an external output terminal of the video tape recorder 17. By using the external signal input terminal 18 and the external output terminal 17a, a single video tape can be used. It can also be used as a recorder.

Further, 10 a is a terminal for connecting the antenna 19, 10 b is a terminal for connecting the whip antenna 20, and 10 c is a terminal for extracting a signal from the tuner section 10. The tuner unit 10 may be configured as a tuner unit having a front end for giga band for receiving satellite broadcasting.

As described above, in the present embodiment, the television circuit A of the television and the recording / reproducing circuit B of the recording / reproducing apparatus are mounted on the same printed wiring board 6, and the printed wiring board is arranged from the rear of the housing 1. Since the guide rails 7 for holding both ends of the printed wiring board 6 are provided so that the 6 can be attached and detached, the cost can be suppressed and a simpler structure can be realized.

[0014]

[Effect of device]

 As described in detail above, according to the present invention, it is not necessary to connect the recording / reproducing apparatus and the television, and the recording / reproducing apparatus and the television can be used without performing the connecting work. Further, since the television circuit and the recording / reproducing circuit are mounted on the same printed wiring board, it is possible to reduce the same parts and the work steps. Furthermore, there is no need to connect printed wiring boards, which facilitates assembly and disassembly. Further, since the guide for gripping the printed wiring board can be one, the structure is simplified.
