Description

[Detailed description of the invention] The present invention relates to a chassis mounting device that can be used when a magnetic recording and reproducing device (hereinafter referred to as VTR) is integrated into a television receiver, and has a simplified structure. The purpose of the present invention is to provide a device that can be installed in a precise location.

In conventional television receivers incorporating a VTR, a structure as shown in Figure 1 was used to attach the VTR chassis to the television receiver's cabinet. That is,
VTR with pre-installed VTR motor and mechanical parts
A chassis 1 for use in the TV cabinet is attached to a mounting frame 2 made by combining metal plates and metal frames with screws 3, while a through hole 5 is fixed in advance to an escutcheon panel 4 of the television cabinet. Attach a mounting frame 7 to this by welding screws 6 toward the back side, fit the through holes 8 of the mounting frame 2 to which the chassis 1 is attached to the screws 6, and tighten the nuts 9 with washers onto the screws 6. Particularly, the chassis 1 can be attached to the escutcheon panel 4.
It was designed to be attached to.

However, in such conventional devices,
Since the chassis 1 was attached to the escutcheon panel 4 via the mounting frame 2 and the mounting frame 7, the structure was complicated, and the mounting position of the chassis 1 with respect to the escutcheon panel 4 was likely to vary. Therefore, there were disadvantages such as a tape holder (not shown) attached to the chassis 1 coming into contact with the peripheral wall of the through hole 5. Furthermore, there were many places to insert screws, nuts, etc. for installation, and the workability of installation was also poor.

Therefore, the present invention solves these conventional drawbacks.
The purpose of this invention is to provide a mounting device for a VTR chassis.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 2 shows a structural part for a VTR used in this device.A mounting piece 11 and a mounting piece 12 for attaching a tape holder are attached to a VTR chassis 10 to which mechanical parts such as a VTR motor and reel are attached in advance. are fixed in advance by spot welding or the like, and a tape holder 13 for mounting the video tape is attached with screws 14, and each mounting piece 1
1 and 12 are provided with a first through hole 15 for attachment and a second through hole 16 for positioning. On the other hand, the third
The figure shows the back side of the escutcheon panel 17 of the cabinet of the television receiver.A through hole 18 for inserting the tape holder 13 is provided on the back side of the escutcheon panel 17. 1 boss 19 and this first boss 19
A second boss 20 for positioning, which is slightly longer than the first boss 20, is provided.

Then, with the tape holder 13 attached to the front of the chassis 10 in advance as described above, the chassis 10 is positioned on the back side of the escutcheon panel 17 by fitting the tape holder 13 into the through hole 18. and the second positioning
The chassis 10 is assembled by fitting the boss 20 and the through hole 16 to position it at a predetermined mounting position, inserting the screw 21 into the first through hole 15 for installation, screwing it into the first boss 19, and tightening it. is attached to a predetermined position on the back side of the escutcheon panel 17.

In this way, the chassis 10 can be directly attached to the escutcheon panel 17 without intervening a conventional attachment frame or attachment frame. Therefore, the structure can be made extremely simple, and the number of parts such as mounting frames and screws can be reduced, so that the workability of mounting can be greatly improved. Further, since the chassis 10 is directly attached and positioned accurately, it can be easily and correctly attached to a predetermined position, and problems such as the tape holder 13 hitting the escutcheon panel 17 are avoided. It is something that can be done.

Note that the first
If the difference between the lengths of the second bosses 19 and 20 is equal to or less than the thickness of the mounting pieces 11 and 12 of the chassis 10 as shown in FIG. It is possible to attach with even greater strength by screwing in the screw 22.

As described above, according to the present invention, the chassis of the mechanical part of the VTR is directly positioned and attached to the escutcheon panel of the television receiver, resulting in a simple configuration and improved workability. Moreover, it is possible to realize a device that can be installed accurately and has great practical effects.
