The present invention provides a mounting device for a recording and reproducing device configured to screw a printed circuit board and a mounting frame to one surface such as the bottom of the recording and reproducing device, and to screw the mounting frame to another device. A flanged pushbutton having a pair of flanges is fitted onto the outer periphery of a screwing bushing provided on one side of the recording/reproducing device, and a part of the mounting frame is fitted between the pair of flanges on the outer periphery of the bushing. By pressing the bushings with the printed circuit board and screwing the printed circuit board to the post, it is possible to install a mounting frame that requires cushioning against the recording/reproducing device, and a mounting frame that does not have such cushioning characteristics. It is designed so that it can be fastened together with a good printed circuit board using a common screw.

[Conventional technology]

Conventionally, when a recording/reproducing device such as a hard disk drive is attached to computer equipment, etc., a printed circuit board and a mounting frame are screwed to the bottom of the recording/reproducing device, and the mounting frame is screwed to the computer equipment, etc. There is a mounting device for a recording/playback device.

In this case, since the recording/playback device attached to the computer equipment etc. via the mounting frame needs to be vibration resistant, the mounting frame must be screwed through a buffer member so that it has cushioning properties for the recording/playback device. There is. On the other hand, if the printed circuit board has a buffering property against the recording/reproducing device, the mutual vibration between them may cause the wiring material wired between the printed circuit board and the recording/reproducing device to be cut or the electronic components mounted on the printed circuit board to be damaged. In order to avoid problems such as interference with the recording/reproducing device and damage, it is better for the printed circuit board to have no cushioning properties for the recording/reproducing device, and the printed circuit board needs to be screwed directly to the recording/reproducing device.

Therefore, in the conventional mounting system #, as shown in FIGS. 4 and 5, the printed circuit board 4 is directly screwed to the screw fixing post 3 provided on the bottom 2 of the recording/reproducing device 1 with screws 5, while The mounting frame 6 was attached to the bottom part 2 via a buffer member 7 so as to have a cushioning property. As the buffer member 7, for example, a metal plate 10 having screws 9 on the upper and lower sides of the buffer rubber 8 and a metal plate 12 having a female threaded hole 11 in the shape of one body is used, and the metal plate 10 is connected to the screws 9. The screws 14 inserted through the mounting frame 6 are screwed into the female threaded holes 11 of the metal plate 12 for installation. Also, in order to prevent the printed circuit board 4 from interfering with the mounting frame 6 and the buffer member 7, a notch 15 and a gap 16 are provided in the printed circuit board 4.
etc. are established. Note that the recording/reproducing device 11/'i is attached to computer equipment etc. via the mounting frame 6,
The shock absorbing member 7 provides vibration resistance.

[Problem to be solved by the invention]

However, the conventional mounting device is attached to the bottom 2 of the recording/reproducing device 1.
Since the printed circuit board 4 and the mounting frame 6 are individually attached using the screws 5 and 14, the number of parts and assembly steps are large, resulting in high costs. In particular, when the buffer member 7 is attached to the bottom portion 2 with screws 9, it takes time and effort to attach the buffer member 7. In addition, the printed circuit board 47jf
Since it is necessary to provide a notch 15 and a gap 16 in the printed circuit board 4 so as not to interfere with the mounting frame 6 and the buffer member 7, the effective area of the printed circuit board 4 is reduced.
There was a problem.

The present invention provides a 5K system that allows a mounting frame that requires cushioning properties for a recording/playback device and a printed circuit board, which is better without such cushioning properties, to be fastened to one side of the recording/playback device using a common screw.
The object of the present invention is to provide a mounting device for a recording/reproducing device.

By screwing the printed circuit board directly to the post, the flanged pusher that is fitted around the outer circumference of the post and sandwiching the mounting frame between a pair of 7 rungs is held down and fixed by the printed circuit board. Since the printed circuit board and the mounting frame can be fastened together using a common screw on one side of the recording/reproducing i&R, the printed circuit board and the mounting frame can be mounted at the same time using a common screw. Therefore, the number of parts and assembly man-hours can be reduced, and costs can be reduced.

The flanged push is easy to install because it only needs to be fitted to the outer periphery of the post and there is no need for screws.

Since the printed circuit board and the mounting frame can be attached in an overlapping manner in the axial direction of the flanged pusher, the effective area of the printed circuit board can be increased.

At the same time, the mounting frame can be mounted in a state where it has a buffering property against the recording and reproducing device due to the elasticity of the flanged push, so the recording and reproducing device that is attached to computer equipment etc. via the mounting frame has optical vibration resistance. can be granted. In addition, since the printed circuit board can be attached to the recording/playback device without any buffering properties, the mutual vibration between the printed circuit boards and the recording/playback device may cause the wiring material between the printed circuit board and the recording/playback device to be cut, or the printed circuit board may be damaged. It is possible to prevent electronic components mounted on the device from interfering with the recording/reproducing device and being damaged.
