Description

[Detailed description of the invention] Industrial application field This invention is based on a magnetic recording and reproducing device that uses a microfloppy disk to support the main body of a magnetic recording and reproducing device when the main body is housed and fixed in a synthetic resin casing. The present invention relates to a support structure for a recording/reproducing device.

Prior Art A support structure for housing and fixing a magnetic recording/reproducing device in a housing is conventionally shown in FIG. 9 or 10.

In the figure, reference numeral 1 denotes the main body of the magnetic recording/reproducing apparatus, which houses a motor for rotating a spindle, a magnetic head, and a microcomputer for controlling these motors, magnetic heads, etc., although not shown. This main body 1 is formed by bending a metal plate, and is housed and fixed in a synthetic resin casing 2.

In the support structure shown in FIG. 9, flange portions 3, 3 projecting laterally are formed at the lower end of the main body 1, while the casing 2 is divided into an upper casing 2a and a lower casing 2b. Seats 4, 4 are provided protrudingly on the bottom surface of the housing 2b, the flanges 3, 3 are placed on the seats 4, 4, and the flange parts 3, 3 are connected to the seats 4, 3 by screws 5, 5. 4
The main body 1 is fixed to the lower casing 2b by being fastened to the lower casing 2b. Note that the upper case 2a is placed over the lower case 2b to which the main body 1 is fixed, and these are fixed using screws or the like (not shown). Furthermore, as shown in FIG. 10, since the flanges 3, 3 protrude laterally, the screws 6, 6 passing through the side plates 2c, 2c of the housing 2 are tightened to the side surfaces of the main body 1. Therefore, in some cases, the main body 1 is fixed to the housing 2.

Problems to be Solved by the Invention The support structure of the conventional magnetic recording/reproducing device described above has the following problems.

As shown in FIG. 9, the main body 1 has flanges 3, 3
In the case where the casing 2 is fixed by the flanges 3, 3, the width of the casing 2 becomes large because the flange portion 3 protrudes to the side, and the device becomes unstable. It had become larger. Furthermore, in the support structure shown in FIG.
Although the width of the main body 1 is not increased, an uneven load is applied to the main body 1 due to the elastic force of the side plates 2c, 2c of the synthetic resin casing 2, and the main body 1 is distorted due to this load. This distortion may cause the position of the magnetic head to shift. Since magnetic recording and reproducing devices record and reproduce information at high density on the surface of a floppy disk, even a slight deviation in the position of the magnetic head will prevent proper recording and reproduction. , body 1
Even if the distortion that occurs is minute, it cannot be ignored.

Purpose: In view of the above-mentioned problems, this invention was developed without increasing the length or width of the casing that houses the main unit, and therefore without increasing the size of the entire device, and also to prevent loads from being applied to the main unit as much as possible. The object of the present invention is to provide a support structure for a magnetic recording/reproducing device.

Means for Solving the Problems In order to achieve this object, the magnetic recording/reproducing device according to the present invention has a main body in which a motor, a magnetic head, a microcomputer, etc. are housed, and is fixed to a synthetic resin casing.

A collar 14b and a washer 14c are attached to the male thread 14a.
The male screws 14a, 14a... are inserted into the main body 1.
It is preferable that the length protruding from the side surface of the collar 14 is adjusted, or the external thread 14a may be a stepped thread instead of the collar 14b. Also,
If the locking protrusions 14, 14, . . . project laterally from the side surface of the main body 11 without using the male screws 14a, 14a, . It doesn't matter if it is etc. Furthermore, although not shown, in the case of a structure in which the bottom cover is placed over the main body 11, the male screws for fixing the bottom cover to the main body 11 are connected to the locking protrusions 14, 14...
It is also possible to use it for both.

A housing 15 that houses the main body 11 is molded from synthetic resin and is divided into an upper housing 16 and a lower housing 17. The main body 11 is placed at an appropriate position on the lower casing 17, and the main body 11 is placed at an appropriate position on the lower casing 17.
An appropriate number of supports 18, 1 determines the placement position of 1.
8... are integrally molded with the lower casing 17. The supporting parts 18, 18... in this embodiment are as follows:

Effects As explained above, the support structure of the magnetic recording and reproducing device according to this invention is a magnetic recording and reproducing device for fixing the main body in which the motor, magnetic head, microcomputer, etc. are housed to the synthetic resin casing. In the support structure, the main body is provided with a locking protrusion that protrudes laterally, the casing is divided into an upper case and a lower case, and the upper case has a clamp that engages with the locking protrusion. A claw is provided, and the lower casing is provided with a support part on which the main body is placed, and the upper casing and the lower casing are fastened with screws or the like, and the locking protrusion is held between the support part and the clamping part. Since it is configured to do so, it has the following effects.

Since the main body is not fixed with screws etc. that pass through the casing, the metal main body is not affected by the elastic force of the synthetic resin casing, and uneven loads are applied to the main body. Therefore, no distortion occurs in the main body. Therefore, positional deviation of the magnetic head etc. is prevented as much as possible, and good recording and reproduction can be performed. Furthermore, since the portion projecting to the side of the main body is the locking protrusion, and this is only a short length, the width of the device does not increase significantly. Moreover, since the structure is simple and can be manufactured easily, it has the advantage of being able to be provided at low cost and being highly practical. Furthermore, when the locking protrusion is a component fixing screw protruding from the side of the main body, the number of parts does not need to be increased, and the product can be manufactured at a lower cost.
