BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view of a unit mounting structure after unit mounting. In both figures, the same parts are designated by the same reference numerals.

The unit mounting structure of the present embodiment basically comprises a base chassis 2 and a slide bracket 4, and 1 is an electronic equipment unit mounted on an electronic device body (not shown). It is a disk drive unit. The base chassis 2 is previously fixed to the main body of the apparatus with screws or the like, and has a mounting surface on which the unit 1 is mounted, and a vertical plate 21 is provided perpendicularly to this mounting surface. Since the vertical plate 21 contacts one side surface of the unit 1, it will be referred to as the contact surface 21 hereinafter.

The base chassis 2 is further provided with two parallel guide rails 3a and 3b below the unit mounting surface.
Is provided, and the slide bracket 4 is supposed to be slidable between the two guide rails 3a and 3b. When the slide bracket 4 slides along this guide rail and one side surface of the unit 1 abuts on the abutment surface 21, the protrusion 8 of the slide bracket 4 engages with the position of the chassis 2 which is engaged. A hole 7 is provided. Further, guide pins 5a to 5c are provided on the contact surface 21, and holes 11a to 11c provided on one side surface of the unit 1 to.
It can be inserted into 11c.

In front of the slide bracket 4, vertical members 41a and 41b perpendicular to a slide plate (a plate having a surface parallel to the unit mounting surface of the base chassis 2) are provided. Elastic spring portions 6a and 6b are attached to 41b. This elastic spring portion 6a,
Reference numeral 6b is for abutting the other side surface of the unit 1 to press and bias this surface. Further, a handle portion 10 is provided in front of the slide bracket 4, and the above-mentioned convex portion 8 is provided on the handle portion. Furthermore,
The vertical members (elastic spring attachment members) 41a, 41b are provided with guide pins 6a, 6b, and can be inserted into holes 12a, 12b provided on the other side surface of the unit 1.

When mounting the unit 1 inside the main body of the apparatus, the unit 1 is placed on the placement surface of the base chassis 2, and then the slide bracket 4 is attached to the base chassis 2.
Slide along the guide rails 3a and 3b provided at the bottom of the. Handle part 10 of slide bracket 4
When the convex part 8 provided on the base chassis 2 hits the base chassis 2,
Due to the elastic deformation of the handle portion 10 made of an elastic member,
The convex portion 8 enters the lower side of the base chassis 2, and the convex portion 8 is engaged and locked in the engaging hole portion 7.

At this time, one side surface of the unit 1 and the contact surface 21 of the base chassis 2 come into contact with each other, and the guide pins 5a to 5a.
5c is inserted into the holes 11a to 11c. Further, since the elastic spring portions 9a and 9b press the other side surface of the unit 1 and elastically deform, the unit 1 is clamped by the elastic springs 9a and 9b and the contact surface 21 to prevent rattling of the unit. Will be done. In addition, the guide pins 6a and 6b have holes 12
a, 12b.

In this way, when the unit 1 is mounted inside the main body of the apparatus, no tools are required and the work can be performed very easily. Further, even when the unit 1 is detached from the main body of the apparatus, the protrusion 8 is disengaged from the engaging hole portion 7 by pushing down the handle portion 10 and can be easily detached. Further, even if the width dimension of the unit 1 is slightly different for each unit, the elastic spring portions 9a and 9b provided on the slide bracket 4 are elastically deformed. It is possible to prevent sticking.

Base chassis 2 and slide bracket 4
If and are connected to each other by a spring spring (not shown), and the unit 1 is attached, and the two are always attracted by the urging force of this spring, the unit is more firmly fixed. It is also strong against vibration. Further, the structure can be realized by using plastic or sheet metal, and therefore, in combination with the elastic spring portions 9a and 9b, it is possible to sufficiently cope with a slight change in the width dimension of the unit 1.

In the above-mentioned embodiment, the convex portion 8 and the engaging hole portion 7 are provided as a pair, but a plurality of pairs may be provided.
The number of guide pins and holes is not limited to the illustrated example. Further, although a disk drive is assumed as a unit, it is needless to say that it can be widely applied to an electronic device unit in general.

[0020]

As described above, according to the present invention, the unit can be mounted inside the main body of the apparatus without using screws and tools, and the number of assembling steps, maintenance and replacement steps can be significantly reduced. The reason is that the unit is sandwiched from both sides, and in addition to the sandwiched structure, a guide pin that is inserted into the hole of the unit is provided, and a locking mechanism for both sandwiched parts (chassis and bracket) is provided. Is.

Further, according to the present invention, even if the width dimension of the unit is slightly different, there is an effect that it can be fixed without rattling. The reason is that it is possible to absorb the variation in the width dimension of the unit by using elastic deformation of plastic or sheet metal.
