DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a television receiver,
It relates to a complex AV device in which a compact disc player (hereinafter, referred to as a CD playback device), an audio tape recorder, and a video tape recorder (hereinafter, referred to as a VTR) are incorporated in the same housing, in order to reduce the influence between devices. Is provided.

[0002]

2. Description of the Related Art Conventionally, a plurality of AV apparatuses such as a VTR and a television receiver, a CD reproducing apparatus and a tape recorder have been used.
Composite AV devices in which the devices are incorporated and housed in the same housing have been commercialized. In the case of such a composite AV device, electromagnetic noise generated from one device may be picked up by the other device, and normal operation may not be expected. For this reason, conventionally, in these composite AV devices, an electromagnetic wave shield is provided between each device.

[0003]

However, in order to eliminate interference between devices, it is necessary to provide more reliable shields, which increases the size of the shield and increases the cost or size of the entire device. This was a factor that prevented weight reduction.

The present invention provides a composite AV apparatus in which a television receiver, a CD reproducing apparatus, an audio tape recorder, and a VTR are incorporated in the same housing, by taking into consideration the arrangement of each device in the housing. This is to reduce interference.

[0005]

In order to achieve the above object, a composite AV device according to the present invention comprises a CD reproducing device and an audio tape recorder positioned in parallel on the left and right above a picture tube of a television receiver. The VTRs are housed in the same housing so that the VTRs are located below the picture tube, and the fly pack transformer of the television receiver is arranged below the CD reproducing device.

[0006]

In a television receiver, a CD player, an audio tape recorder and a VTR, the television receiver has the most adverse effect on other devices.
It is a fly-pack transformer even in a television receiver. On the other hand, the devices most susceptible to other devices are:
It is an audio tape recorder. According to the above-described configuration, the fly-pack transformer, which has the most adverse effect, and the audio tape recorder, which is most susceptible, are located far from each other without interfering with the operation of each device, so that interference between them is reduced. Is what is done.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a perspective view showing an embodiment of an AV composite device according to the present invention, and FIG. 2 is a rear view schematically showing an internal structure thereof. 1 and 2,
6 is a picture tube of a television receiver, 6a is a neck portion of the picture tube, 9 is a CD reproducing device, 10 is an audio tape recorder, 2 is a VTR, and these are housed in the same casing 1. Have been. Note that reference numeral 2a denotes an insertion port of the video cassette.

The CD reproducing device 9 and the audio tape recorder 10 are arranged in parallel on the right and left of the picture tube 6 above the picture tube 6 with the neck portion 6a of the picture tube 6 as the center.
R2 is disposed below the picture tube 6. Reference numeral 3 denotes a printed circuit board of the television receiver, and reference numeral 5 denotes a fly-pack transformer of the television receiver fixed to an arm 4 set on the printed circuit board 3 so as to be located below the CD reproducing device 9. Are located in 12 is C
A shield plate for electromagnetically shielding the portion where the D playback device 9 and the audio tape recorder 10 are arranged and the television receiver unit, and 11 electromagnetically shields the television receiver unit and the VTR 2. It is a seal plate.

[0009]

As described above, according to the present invention, the fly-pack transformer, which adversely affects other devices, and the audio tape recorder, which are most susceptible, are located apart from each other. Is reduced, the shield structure can be simplified accordingly,
Since the CD playback device and the audio / tape recorder are arranged at the top of the housing, the mechanism for exchanging CD disks and cassettes can be simplified.
