[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an extension unit. In recent years, small electronic devices such as notebook personal computers have been widely used. In such small electronic devices, the number of slots for expansion or external devices such as a hard disk device has been reduced due to the small size of the device housing. Problems have been pointed out that there is a limitation on storage of the storage device and the like.

Under such circumstances, there has been proposed an extension unit that accommodates only the extension function of the above-mentioned small electronic equipment.

[0003]

2. Description of the Related Art FIG. 6 shows a main part of a conventional extension unit. In this conventional example, the extension unit is
And a palm rest 3 which is provided on the front of the cradle 2 so as to be able to be pulled out.
It is held on the upper surface. In FIG. 6, reference numeral 5 denotes a keytop of the device 1.

In order to prevent the device 1 held on the cradle portion 2 from easily falling off, or to prevent only the device 1 from rising from the cradle portion 2 when the tip of the device 1 is lifted. At the top of the palm rest 3, the device 1
The pressing piece 4 that presses the tip of is formed integrally.

[0005]

However, in the above-mentioned conventional example, the pressing piece 4 is formed integrally with the palm rest 3, and the thickness of the device 1 held on the cradle portion 2 varies depending on the model. In addition, there is a disadvantage that it is necessary to prepare a plurality of types of palm rests 3 in which the holding pieces 4 are adjusted to the thickness of the model.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and has as its object to provide a structure of an extension unit which can support a plurality of models.

[0007]

According to the present invention, the above-mentioned object is achieved, as shown in FIG. 1 corresponding to the embodiment, by a receiving portion 2 for holding a small electronic device 1 on an upper surface, and a receiving portion 2. A palm rest 3 that can be pulled out from the front of the palm rest, and an inverted L-shaped pressing piece 4 projecting from the upper end of the palm rest 3 so as to be adjustable in height.
This is achieved by providing a structure of an extension unit that presses the distal end portion of the extension unit with the retaining piece 4 to prevent the extension unit from falling off.

[0008]

In the present invention, the palm rest 3 has a pressing piece 4 for pressing the front end of the device 1 placed on the upper surface from above. This presser piece 4 is adjustable in height,
Absorbs differences in thickness between models, improving versatility.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows an extension unit according to the present invention.
Are formed.

The main unit 6 includes a hard disk drive,
A floppy disk drive 7 or a printed circuit board for various I / Os is accommodated therein. A rear end of the receiving section 2 for holding a small electronic device 1 such as a notebook computer is connected to the device 1. Are arranged.

On the other hand, the palm rest 3 can be pulled out from the front end of the cradle portion 2, and the device 1 is supported by the palm rest 3 and the cradle portion 2 pulled out from the cradle portion 2. The palm rest 3 has a pressing piece 4 having an L-shaped cross section that protrudes upward, so that the front end of the device 1 can be pressed from above to prevent the device 1 from being detached or floating. Has been.

2 and 3 show the structure of the palm rest 3. FIG. The palm rest 3 includes an upper case 10 having a step 9 for locking the front end rear surface of the device 1,
The holding piece 4 is formed in a hollow shape having a lower case 11 joined to the holding piece 4 and held by a holding piece adjusting mechanism 12 housed therein so that the height of the holding piece 4 can be adjusted.

The presser piece adjusting mechanism 12 has an L-shaped fixture 14 fixed to a boss 13 bulging in the lower case 11.
A screw hole 15 is provided in the rear wall 16a, and a holding piece 16 having a U-shaped cross section sandwiching the fixing metal 14 and the side edge of the holding piece 4 between the opposing side walls 16b, 16b. A fixing screw 18 is inserted through the hole 14 a and the long hole 17 of the holding piece 4 and screwed into the screw hole 15 of the holding piece 16.

The head 18a of the fixing screw 18 is exposed to the outside of the lower case 11. By operating the head 18a, the holding piece 16 is called into the fixing bracket 14 and the holding piece 4 is fixed. You. In order to prevent the fixing screw 18 from dropping off from the holding piece 16 when the fixing screw 18 is loosened, it is desirable to project a stopper at an end of the fixing screw 18. The dimension a in the figure is smaller than the dimension b so that the holding piece 16 can be reliably called into the fixture 14 by operating the fixing screw 18.

Therefore, in this embodiment, first, after the palm rest 3 is pulled out from the main body 6 and the device 1 is placed thereon, the holding piece 4 is pressed so that the horizontal piece of the holding piece 4 can press the upper surface of the front end of the device 1. Is adjusted, and then the fixing screw 18 is tightened, whereby the device 1 is fixed.

FIG. 4 shows a second embodiment of the present invention. In this embodiment, an appropriate number of V-shaped notches 19, 19,... Are provided on the side edges of the holding piece 4, and the holding piece adjusting mechanism 12
It is formed by a lock piece 20 having a V-shaped tip so as to match the V-shaped notch 19. The lock piece 20 is movable in the direction of arrow A in FIG. 4 by a guide member (not shown), and is urged toward the holding piece 4 by a spring 21. The lock piece 20 has a button 22 on a side wall portion.
Is exposed from the lower case 11 to the outside so that operation from the outside is possible.

Therefore, in this embodiment, the button 2
2 to release the lock between the lock piece 20 and the presser piece 4 while pulling the presser piece 4 upward.
The device 1 is fixed simply by pressing down on the device 1 until it comes into contact with the upper surface of the device 1.

FIG. 5 shows a third embodiment of the present invention. In this embodiment, the holding piece 4 is, for example, an injection-molded product of a synthetic resin material, and a screw 23 is provided upright at the center of the front wall. On the other hand, the holding piece adjusting mechanism 12 has a disc-shaped member 25 whose upper and lower surfaces are pressed by holding pieces 24, 24 projecting from the lower case 11 or the upper case 10 and screwed into the screw rod 23. By rotating a portion of the disc-shaped member 25 exposed from the case, the pressing piece 4 can be held at an arbitrary height.

[0019]

[Effects of the Invention] As is clear from the above description, according to the structure of the extension unit of the present invention, the height of the protrusion of the holding piece can be freely adjusted, so that it can be used for a plurality of models, and the versatility can be achieved. Can be increased.
