A first mounting frame is provided in the longitudinal direction and has a claw at its rear end that engages with the lower guide hole on the rear surface of the casing, and a fixing piece that comes into contact with the bottom surface of the casing at its front end; has a claw at the rear end that engages with the upper guide hole on the rear surface of the casing, a step for a stopper at the middle part, and a fixing piece at the front end that comes into contact with the hanging piece. A frame is provided, and a stopper piece having a recess into which the fixing piece can be fitted is provided on the front surface of the hanging piece, and a stopper piece having a locking part with the step for the stopper is provided so as to be movable up and down. This is achieved by providing a unit mounting structure characterized in that the fixing pieces of the first and second mounting frames are fixed to the housing by inserting the unit into the housing.

(5) Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail based on the attached drawings.

FIG. 2 is a front view showing the unit mounting structure according to the present invention. Reference numeral 11 is a unit such as a device in, for example, a floppy disk device, and reference numeral 12 is a casing serving as a mounting frame for the unit 11. One or more units 11 are detachably attached to the interior of the housing 12. In addition, in FIG. 2, the reference numeral 13 is a mounting member for fixing the housing 12 to the rack.

As shown in FIG. 3, a hanging piece 15 is provided on the upper edge of the entrance opening 14 of the housing 12. As shown in FIG. This hanging piece 15 is for fixing the unit 11 to the housing 12, and is provided in the width direction of the housing 12 with an appropriate vertical width. Furthermore, a guide rail 17 is provided on the inner bottom surface 16 of the housing 12. This guide rail 17 is for guiding the insertion of the unit 11, and is for guiding the insertion of the unit 11.
It has locking pieces 18, 18 extending from the front side toward the rear side and facing each other inwardly.

Unit 11 inserted into the housing 12
As shown in FIG. 4, a first mounting frame 19 is provided on the lower surface of the holder. This first mounting frame 19
is engaged with the guide rail 17 of the housing 12 on the lower surface of the unit 11, and the locking pieces 18,
It has engagement pieces 20, 20 that engage with the housing 18, and a claw 2 that protrudes at the rear end so as to engage with the lower guide hole 21 on the rear surface of the housing 12 shown in FIG.
2, and has a fixing piece 23 at its front end that is bent inward of the housing 12 and comes into contact with the bottom surface 16 of the housing 11, as shown in FIG. Also,
A second mounting frame 24 is provided on the upper surface of the unit 11, as also shown in FIG.
This second mounting frame 24 is for fixing the unit 11 to the housing 12 on the upper surface of the unit 11, and has rising pieces 25, 25 along its longitudinal direction.
The rising pieces 25, 25 have stopper step portions 26, 26 at the rear of the intermediate portion thereof, and the rear ends thereof are configured to engage with the upper guide hole 27 on the rear surface of the housing 12 shown in FIG. It has a protruding claw 28, and at its front end a fixed piece 29 that stands up so as to come into contact with the front surface of the hanging piece 15 shown in FIG. Note that the reference numeral 30 is a through hole made in the fixing piece 29.

A stopper piece 31 is provided on the front surface of the hanging piece 15 of the housing 12, as shown in FIG. This stopper piece 31 holds the unit 11 in the housing 1.
This prevents the unit 11 from falling out when pulled out from the second mounting frame 2, and has a recess 32 at a predetermined location into which the fixing piece 29 of the second mounting frame 24 can fit, and the side edges of this recess 32 are This serves as a locking portion 33 for the stopper step portion 26, and furthermore, elongated holes 34 are bored at appropriate locations for attaching to the hanging piece 15 so as to be movable up and down.

The unit 11 is installed in the housing 12 configured in this way.
To install them together, do the following: First, the unit 11 is installed inside the casing 12 shown in FIG.
is inserted by engaging the engaging pieces 20, 20 of the first mounting frame 19 provided on its lower surface with the guide rail 17 of the housing 12. At this time, as shown in FIGS. 5 and 6, the claws 22 at the rear end of the first mounting frame 19 and the claws 28 at the rear end of the second mounting frame 24 are drilled into the rear surface of the housing 12, respectively. It engages with the provided lower guide hole 21 and upper guide hole 27 to prevent the rear part of the unit 11 from steadying. In this state, as shown in FIG. 2 and FIG. Fix the fixing piece 29 at the front end of the housing 12 from the front side of the housing 12 by passing through the through hole 30 of the fixing piece 29 with a bolt 36 or the like and screwing it into the screw hole 37 (see FIG. 3) of the hanging piece 15. . Next, as shown in FIG.
The stopper piece 31 is fixed by passing a bolt 38 or the like from the front side of the stopper piece 31 through the long hole 34 of the stopper piece 31 and screwing into the screw hole 39 bored in the hanging piece 15. At this time, the stopper piece 31 is set at the lowest position so that the locking part 33 of the stopper piece 31 engages with the stopper step part 26 of the rising piece 25 shown in FIG. . In this way, the unit 11 is mounted inside the housing 12, as shown in FIG. To pull out the unit 11 during maintenance,
All you have to do is remove the bolts 35 and 36 from the front side of the housing 12, release the fixation of the first mounting frame 19 and the second mounting frame 24, and pull them toward you. At this time, when the unit 11 is pulled out almost completely, the stopper step 26 of the second mounting frame 24 engages with the locking part 33 of the stopper piece 31, as shown in FIG. are prevented from falling off. To fix the unit 11 again after completing maintenance, push the unit 11 into the housing 12 and remove the bolts 3 from the front side of the housing 12 as described above.
5, 36, etc. may be screwed together. Here, when removing the unit 11 from the housing 12 and replacing it,
Loosen the bolt 38 from the front side of the housing 12 shown in FIG. 7, move the stopper piece 31 to the uppermost position using its elongated hole 34, and in this state remove the bolts 35 and 36 as described above. When the unit 11 is pulled out, the unit 11 can be pulled out from the housing 12 without the locking portion 33 of the stopper piece 31 engaging with the stopper step portion 26 of the second mounting frame 24.

(6) Effects of the invention Since the invention is constructed as described above, the casing 1
The unit 11 can be attached and detached by simply tightening and removing the bolts 35, 36, 38, etc. from the front side of the unit 2. Therefore, the attachment/detachment and insertion/removal operations can be performed only from the front side without having to go around the side or rear side of the unit as in the conventional case. Further, since the number of bolts and the like for fixing the unit 11 can be reduced, operations for attaching and detaching the unit and inserting and extracting the unit can be simplified. Furthermore, since the stopper piece 31 can be easily moved up and down using the elongated hole 34, if the stopper piece 31 is moved upward and the unit 11 is pulled out, the unit 11 can be easily moved outside the housing 12. It can be taken out. Therefore, maintenance work such as inspection and maintenance of the unit 11 can be performed extremely easily.
