Description

[Detailed Description of the Invention] This invention relates to a component mounting device for a magnetic recording and reproducing device, and is configured to mount a plurality of components using the outer periphery and shaft end face of a single mounting shaft.

Conventionally, when the operating lever is slidably mounted on the board, a mounting shaft is required for sliding guidance, and when the flywheel is mounted on the board with a thrust receiving plate, a mounting shaft is required to fix the thrust plate. was needed.

For this reason, it is necessary to install each mounting shaft on the board, and in the case of a small magnetic recording/reproducing device where there is not enough space for components, it is difficult to find space for the mounting shafts.

The present invention has been proposed in view of these points, and embodiments shown in the drawings will be described below.

Reference numerals 1 and 2 are fast forward and rewind operation levers, which use openings 4 and 5 provided in the base plate 3 as one guide, and accommodate a mounting shaft 7 implanted downward from the base plate 3 in a long hole 6 formed at one end. By doing so, the mounting shaft 7 is slidably mounted using the outer periphery of the mounting shaft 7 as the other guide. Reference numeral 8 denotes a return spring wound around the outer periphery of the mounting shaft 7, the left and right ends of which are locked to the bent pieces 9, 10 of the fast-forward operation lever 1 and the rewind operation lever 2,
When the fast forward or rewind levers 1, 2 are operated, they function to return to their original positions.

Although not shown, the drive mechanism is configured to switch to the fast forward or rewind state when a fast forward or rewind operating lever is operated.

11 is the thrust receiving plate of the flywheel 12;
One end is fixed to the board 3 with a screw 13, and the other end is fixed with a screw 14 to a screw hole formed in the end face of the mounting shaft 7.

As mentioned above, the device of the present invention has a
The operating lever is slidably guided using the outer circumference of the book mounting shaft, and a return spring for returning the operating lever to its original position from the operating position is wound around the outer circumference of the mounting shaft; Furthermore, since the thrust receiving plate of the flywheel is fixed to the end face of the mounting shaft with screws, one mounting shaft can be effectively used for sliding guidance and fixing of multiple parts. This device is useful as a parts mounting device for small magnetic recording and reproducing devices where space is limited.
