PURPOSE:To make easy the function selecting operation and the sound quality/ picture quality adjusting operation of an equipment main body, and to make the extension of functions easy by loading and unloading freely a signal process equipment having the adjusting and storing function of sound quality and picture quality for an audio signal and a video signal on the equipment main body. CONSTITUTION:A signal process equipment 22 consists of a signal selector 221 which selects a video signal input from each of such sources as a television tuner, a video tape deck, a video disk etc., a signal processor part 222 which obtains color drive signals R, G and B from the selected input signal, a control amplifier 223 which fetches in a sound signal from the selected input signal and adjusts an output, a microcomputer 224 for the adjustment and storing of the sound quality and the picture quality for the audio signal and the video signal, a visual mode selector 225 for the sound quality, the picture quality and the adjustment of the picture quality and a preset part 226 etc. At the signal process equipment 22 and the equipment main body 21, each of a video display system and a sound output system is respectively connected with a cable 23 (in unloading) or a connector (in loading) and the signal process equipment 22 and a source microphone are connected with a cable.

Description

[Detailed description of the invention]

[Industrial Application Field 1] The present invention relates to a display device, particularly for a multipurpose display device. The present invention relates to a multifunctional display device. [Prior art 4ig] Conventionally, as a multi-purpose, multi-functional display device, one shown in FIG. 3 is known. First, in the figure, the symbol @11 is the main body of the device, and the main body 11 of the device is equipped with a microphone mixing back 12. RGB back 13. A function selection device such as a stereo TV tuner bag 14 is configured to be selectable and detachable, and by selectively attaching each bag 12 to 14, images such as lyrics and scenes are played back on the screen of the device body 11, and connected to a Soma speaker or the like. Amplifier,
The applicant has already proposed speakers capable of outputting audio (for example, Japanese Patent Application No. 58-1609
(See No. 11). [1 Problem that Ming is trying to solve 1 With conventional display devices, function selection! l! 1v! k
is attached to the main body 11 of the device, and images and sounds can be obtained by selecting functions using the remote controller 15 or the like. However, there is the trouble of having to selectively attach a function selection device each time depending on the purpose of use of the display device, and since the function selection device is attached to the device body 11 for use, the input/output with the device body 11 is inconvenient. There was a problem in that the types of signals were restricted, and as a result, l[: of the device body 11 was also limited.

[Means to solve problems] In view of the above-mentioned problems, the present invention configures a signal processing device having a function of adjusting and storing sound quality and image quality of audio signals and video signals in a display device main body in a detachable manner, thereby increasing the degree of freedom in installing the signal processing device. This allows selective installation of function selection devices at hand. 【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 shows a configuration diagram of a display device according to the present invention, and in the figure, old symbols indicate the main body of the device, which includes a cathode ray tube, a deflection circuit, a power amplifier for audio signals, a speaker, etc.
The device main body 21 includes a device storage pocket 21A with an open front surface. Reference numeral 22 denotes a signal processing device having a sound quality/image quality adjustment storage function and a signal processing function for audio signals and video signals, and the device main body 21 is connected to the signal system and power supply by attaching it to the device storage pocket 21A or by using the signal cable 23. is made possible. Signal processing equipment 22 is coupled by cable connections to sources such as television tuners, video tape decks, video discs, and audio signal sources such as microphones. FIG. 2 shows the circuit configuration of the signal processing device 22 and the device main body 21. As shown in FIG. First, the device main body 21 includes a cathode ray tube 211
A video display system is composed of the deflection circuit 212 and the like, and the power amplifier 213 . Speaker 214. Headphone jack 21. The audio output system is composed of the following. The signal processing device 22 includes a signal selector 221 that selects a video signal input from each source such as a television tuner, a video tape deck, and a video disc, and a signal processor section 22 that obtains a color drive signal RGB from the selected input signal. □ and a control amplifier 22 that takes in the audio signal from the selected input signal and adjusts the output! , a microcomputer 224 for adjusting and storing sound quality and picture quality of audio signals and video signals, and a sound quality and picture quality Y411.
It is composed of a visual mode selector 225 for i, a preset section 22@, etc. Signal processing equipment 2
2 and the device main body 21, the video display system and the audio output system 2 are
Each is connected by a cable 23 (when installed) or a connector (when installed), and the signal processing device 22, the source, and the microphone are connected by cable. With this configuration, the signal processing device 22 can be connected to the device main body 21.
There is a lot of flexibility in installation, as it can be used by attaching it to the camera or by placing it close to the viewing position. When the signal processing device 22 is installed at hand, source selection and visual mode selection are performed at the viewing position. Facilitate audio signal adjustment. Also, the type of source connected to the signal input terminal is υ
To facilitate the expansion of functions of a device main body 21 without any reduction. J5, in the above embodiment, the signal processing device 22 and the device main body 2
Although the connection with 1 is shown using a cable or a connector, it is of course possible to use a wireless connection. [Effects of the Invention] As described above, according to the present invention, since the signal processing unit having the function of adjusting and storing the sound quality and image quality of audio signals and video signals is removably configured in the main body of the device, it is possible to select the functions of the main body of the device. Easy operation and sound/picture quality adjustment operations,
Moreover, it has the effect of facilitating functional expansion.
