Thus, the part as a CD player and the part as a television or radio receiver are the same. When they are installed in the housing and driven by the same power source, measures must be taken to eliminate the adverse effects of noise that affects each other.

That is, noise radiation due to a high-frequency clock for digital processing in the CD player section may jump into an RF system circuit in a television or a radio tuner and adversely affect reception sensitivity and a beat on the screen. . Further, the leakage magnetic flux of the deflection yoke provided in the CRT monitor 2 is magnetically coupled to the coil system (such as the biaxial mechanism) of the optical head of the CD player unit, which causes electromotive force and causes a data reading error from the disk.

For example, assuming that the clock frequency is 16.9 MHz, the frequency of its 10th harmonic (around 160 MHz) is
That is, it becomes the RF frequency, and such harmonic radiation is the most R
Since the F system is adversely affected, it is possible to effectively eliminate the adverse effect on the RF substrate 23 by blunting the clock to some extent (making the edge gentle) and reducing the harmonic components.

Further, as shown in FIG. 5, the circuit portion of the clock oscillator 27 is covered with an iron plate shield 27s to shield the radiation. By adopting these configurations, it is possible to eliminate the decrease in reception sensitivity and the occurrence of beats due to the clock oscillator 27 and the RF substrate 23 being in the same housing.

Further, it is preferable to minimize the radiation source by setting the wiring pattern of the clock signal on the CD substrate 22 as short as possible. Also, C

(C) Video / audio source selection switching operation associated with operation Video / audio source selection switching operation based on operation of user operation keys 5a to 5d, that is, audio output selection circuit 42 and An example of the switching control operation of the video output selection circuit 43 is shown in FIG.
The flowchart will be described. Although the operation keys 5a to 5d also function as power-on operation keys as described above, the power supply operation is omitted in FIG. In addition, CD playback operation, TV reception output operation, etc. are also operated with the operation key 5
Although the execution is started based on the operations of a to 5d, these processes are also omitted.

When the controller 30 is turned off (during standby) and operated in any mode, the CD selection key 5b and the TV selection key 5 are selected in steps F101 to F105.
The operation of d, the radio selection key 5c, the external input selection key 5e, and the multi selection key 5a is monitored.

If the CD selection key 5b is pressed, the process proceeds to step F106, and it is first determined whether or not the disc D is loaded. If the disc D is not loaded, or if another type of disc that cannot be supported is loaded and it is determined that there is no disc, the process is not performed (F106 → NO).

When the existence of the disk D is confirmed,
If the CD, CD-G, or video CD is loaded, and if it is a video CD, step F1
Proceeding from 07 to F109, the audio output selection circuit 42 and the video output selection circuit 43 are connected to the T _MPEG terminal. Therefore,
At the same time, the playback operation is performed by the operations of the optical head 31, the video CD decoder 35, the spindle motor 36, and the like, so that the playback audio (A _MPEG ) and video (V _MPEG ) of the video CD are output to the speaker unit 3 and the CRT monitor.

The reproduced sound (A _CDG ) and the video (V _CDG ) are output from the speaker unit 3 and the CRT monitor 2. Of course, at this time, the switch 32 is connected to the CD / CD-G decoder 33 side.

If the loaded disc D is a normal CD, the process proceeds to step F111, where CD-G
The audio output selection circuit 42 is connected to the T _CD terminal in the same manner as in the above case. Therefore, when the reproducing operation is executed at the same time, the reproduced sound (A _CD ) of the _CD is output from the speaker unit 3. However, in this case, since there is no video signal, the CRT monitor 2 is turned off if the operation of the CRT monitor 2 is being executed in the TV mode or the like until then, and if the CRT monitor 2 is off, it is left as it is. At this time, the switch 32 is also the CD / CD-G decoder 3 similarly.
It is connected to the 3 side.

In order to indicate the mode in which the sound or sound and image of any one of the CD, the CD-G, and the video CD is output in this way, "CD" is displayed on the display unit 4 as shown in FIG. Display the character part (F
112).

By pressing the CD selection key 5b in this manner, the CD mode is set, and the audio output selection circuit 42 and the video output selection circuit 43 are automatically selected. Furthermore, at this time, since the automatic selection according to the type of the loaded disc D is also performed, the user need not pay attention to the type of the loaded disc D.

When the TV selection key 5d is pressed, the controller 30 connects the audio output selection circuit 42 and the video output selection circuit 43 to the T _TV terminal (F113). Then, the display section 4 displays "TV" (F114). Therefore, at the same time, the reception operation of the TV tuner 40 is controlled to be executed in the TV mode, that is, the speaker unit 3 and the CRT monitor 2 output the audio (A _TV ) and the video (V _TV ) of the television broadcast. .

When the radio selection key 5c is pressed, the controller 30 connects the audio output selection circuit 42 to the T _RA terminal. In this case, however, since there is no video signal, the CRT monitor in TV mode etc. Two
If the operation of is executed, the CRT monitor 2 is turned off,
If the CRT monitor 2 is off, leave it as it is.
(F115). Then, the display unit 4 is caused to display "RADIO" (F116). Therefore, the reception operation of the radio tuner 39 is executed at the same time, whereby the operation in the radio mode, that is, the speaker unit 3 outputs the audio (A _RA ) of the radio broadcast.

When the external input selection key 5e is pressed,
The controller 30 connects the audio output selection circuit 42 and the video output selection circuit 43 to the T _IN terminal (F117). Then, the display section 4 is caused to display "VIDEO IN" (F118). Therefore, the audio (A _IN ) and the video (V _IN ) supplied from the external video device are the speaker unit 3 and the CRT.
It will be output from the monitor 2.

As described above, the CD selection key 5b, the radio selection key 5c, the TV selection key 5d, and the external input selection key 5e.
With respect to, the state of each mode is automatically set according to the operation, and the operation is started. Therefore, the user only needs to select the source, and the complicated output switching operation is not necessary at all. Of course, it is not necessary to discriminate the type of CD and operate as described above.

In this embodiment, a multi-selection key 5a is further provided. As an example of this operation, the multi-selection key 5a is used for the CD reproduction signal and the TV or external input signal to the speaker section 3 and the CRT monitor. 2 is the operation key for composite output.

When the multi-select key 5a is pressed, it is first determined whether the disc reproducing operation has been executed in the CD mode or the TV mode or the external input mode operation has been executed so far (F119, F120). ).

If the multi-select key 5a is pressed in the CD mode, the process proceeds to step F121, where the audio output selection circuit 42 does not switch, that is, the T _CD terminal or the T _CD terminal.
_{Although the MPEG} terminal is still connected, the video output selection circuit 43 is switched to the T _TV terminal. At this time, if a normal CD is being played in the CD mode, C
The RT monitor 2 is off, but in such a case, the CRT monitor 2 is simultaneously turned on. Then, the operation of the TV tuner 40 is started. Therefore CR
The TV image (V _TV ) is output on the T monitor 2, and the disc playback sound (A _CD or A _CDG or A) output before the multi-selection key 5a is pressed on the speaker unit 3 is output.
_MPEG ) is continuously output. Regarding the display unit 4, "T
The display of "V" and "CD" is executed to indicate that the mode is multi-mode (F122).

When the multi selection key 5a is pressed in the TV mode or the external input mode, steps F120 to F1
23. First, it is determined whether or not the disc D is loaded. And if a video CD is loaded,
The audio output selection circuit 42 is connected to the T _MPEG terminal to start disk reproduction. At this time, the video output selection circuit 43 is not switched (F124 → F126). Therefore, CR
The T monitor 2 outputs the TV image (V _TV ) or the external input image (V _IN ) that was output before the multi-selection key 5a was pressed, and the speaker unit 3 outputs the video CD.
The reproduced sound (A _MPEG ) is output.

If the CD-G is loaded,
The audio output selection circuit 42 is connected to the T _CD terminal to start disk reproduction, and at this time, the video output selection circuit 43 is not switched (F125 → F127). Therefore, the CRT monitor 2 outputs the TV image (V _TV ) or the external input image (V _IN ) that has been output before the multi-selection key 5a is pressed, and the speaker unit 3 reproduces the CD-G reproduced sound (A _CDG ) is output.

Further, when a CD is loaded, the audio output selection circuit 42 is connected to the T _CD terminal to start disc reproduction, and at this time, the video output selection circuit 4
3 does not switch (F128). Therefore, on the CRT monitor 2, the T output that was output before the multi-selection key 5a was pressed.
The V video (V _TV ) or the external input video (V _IN ) is output, and the speaker unit 3 outputs the reproduced sound (A _CD ) of the _CD .

After the processing of these steps F125, F127 or F128, the display section 4 displays "TV" and "CD" or "VIDEO I".
"N" and "CD" are executed to indicate that the mode is multi-mode (F129). If it is determined in step F123 that there is no disc, the CD operation is not possible and the operation of the multi-selection key 5 is invalid.

If the time when the multi-select key 5a is pressed is neither the CD mode, the TV mode, nor the external input mode, that is, the power is off or the radio mode, is the disc D first loaded? It is determined whether or not (F130). If it is determined in step F130 that there is no disc, the composite operation of disc playback audio output and TV broadcast video output cannot be performed even though the multi-selection key 5a is pressed. Therefore, in step F131, the audio output selection circuit 42 and the video output selection circuit 43 are connected to T _TV , and the TV sound (A _TV ) is output from the speaker unit 3.
, And the TV image (V _TV ) from the CRT monitor 2, that is, the operation in the TV mode. In this case, "TV" is displayed on the display unit 4 (F132).

When the multi-selection key 5a is pressed and the disc D is loaded when the power is off or in the radio mode, if the disc D is a video CD, the audio output selection circuit 42 is connected to the T _MPEG terminal. Further, the video output selection circuit 43 is connected to the T _TV terminal to start the disc reproducing and TV receiving operations (F131 → F135). Therefore CR
The TV image (V _TV ) is output from the T monitor 2, and the reproduced sound (A _MPEG ) of the video CD is output from the speaker unit 3.

If a CD-G is loaded,
The audio output selection circuit 42 is connected to the T _CD terminal and the video output selection circuit 43 is connected to the T _TV terminal to start the disc reproducing and TV receiving operations (F132 → F134). Therefore,
The CRT monitor 2 outputs a TV image (V _TV ) and the speaker unit 3 outputs a reproduced sound (A _CDG ) of a video CD.

Further, when a CD is loaded, the audio output selection circuit 42 is connected to the T _CD terminal and the video output selection circuit 43 is connected to the T _TV terminal to start the disc reproducing and TV receiving operations (F132). → F133). Therefore, C
The RT monitor 2 outputs a TV image (V _TV ) and the speaker unit 3 outputs a reproduced sound (A _CD ) of a _CD .

After the processing of these steps F133 or F134 or F135 is performed, the display section 4 displays "TV" and "CD" to indicate that the mode is multi-mode (F122). ).

As described above, the AV composite device 1 of this embodiment

When the D-G playback sound (A _CDG ) is output,
When the multi selection key 5a is pressed, the audio output selection circuit 42 is set to the T _TV terminal and the video output selection circuit 43 is set to T _CD.
By switching to the terminal, the CRT monitor 2 outputs the reproduced video (V _CDG ) of the CD-G, and the speaker unit 3 outputs the TV sound (A _TV ). Also, after such a source replacement, if the multi-selection key 5a is operated again, the original state may be restored.

When performing such processing, the CD
Is being reproduced (that is, when there is no reproduced image), the operation of the multi-selection key 5a is invalidated, or the TV sound and the TV are displayed on the speaker unit 3 and the CRT monitor 2.
The video may be output.

In addition to this, a process of switching the speaker unit 3 or the source on the CRT monitor 2 side when the multi selection key 5a is pressed in the multi mode is also conceivable.

Switch to change the audio output source. T _CD (or T _CDG or T _MPEG ) → T _RA → T _TV → T _IN → T
_CD (or T _CDG or T _MPEG ) → ・ ・ ・ ・ ・ ・

Similarly, as a method of switching the source on the CRT monitor 2 side, each time the multi-selection key 5a is pressed, the audio output selection circuit 42 remains fixed and the video output selection circuit 43 is toggled as follows. Switch to and change the video output source. T _TV → T _IN → T _CDG (or T _MPEG ) → T _TV → ... In this case, if the disc D being reproduced is a CD, T _TV → T _IN → T _TV it is preferable that to switch alternately the video from the TV broadcast and the external input and so on ....

Besides this method, an operation mode executed prior to the multi-mode may be set. For example, if the disk D loaded when the multi-operation key 5a is pressed is a video CD or a CD-G, both the audio and the video are set to the disk playback audio and the video without setting the multi-mode. May be.

Further, as the combination of sources in the multi-mode, all combinations are conceivable depending on the circuit configuration of the equipment and the number of equipment parts to be sources.
For example, when the CD player unit, the TV tuner unit, the radio tuner unit, and the external input unit are mounted as audio and video sources as in the embodiment (although some circuit configuration changes may be required), other than the above Also, radio audio and external input video, radio audio and CD-G video, radio audio and video CD video Radio audio and TV video, external input audio and TV video, external input audio and CD-G video, external input audio Multi-mode operation such as video CD image, TV sound and external input image is possible.

In addition, the operation keys 5a are provided so that the user can freely enjoy all kinds of multi-mode operations.
In place of the operation keys 5a to 5e, or in addition to the operation keys 5a to 5e, operation keys may be configured as shown in FIG. That is, as the switching operation keys of the audio output selection circuit 42, the TV audio selection key 50a, the CD audio selection key 50b, the external input audio selection key 50c, and the radio audio selection key 50d.
And a TV image selection key 51a and a CD image selection key 51 as switching operation keys of the video output selection circuit 43.
b, an external input image selection key 51c is provided. The controller 30 operates the operation keys 50a to 50d, 51a.
The audio output selection circuit 42 and the video output selection circuit 43 are switched according to the operation of 51c. A power-on key 52 and a power-off key 53 are also provided as needed.

By thus providing the operation keys so that the audio output selection circuit 42 and the video output selection circuit 43 can be arbitrarily switched by the user operation, it is possible to realize the multi-mode enjoyment according to the individual user. become.

Note that such an operation key is also suitable as, for example, a slide switch type or a rotary switch type, and the audio output selection circuit 42 and the video output selection circuit 43 are mechanically contacted according to the slide switch or the rotation switch. May be switched.

The present invention is not limited to the above examples, and various modifications can be considered. In addition to the above, the source device to be installed may be a mini disc player, D
AT player, compact cassette tape player, 8
There are various AV devices such as a milli VTR.
