Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of an expansion unit. In recent years, small electronic devices such as notebook type personal computers have been widely used. However, in such small electronic devices, the number of slots for expansion or external devices such as a hard disk device is small because the device housing is small. It has been pointed out that there is a limit to the storage of storage devices.

Under such circumstances, an expansion unit that accommodates only the expansion function of the small electronic device has been proposed.

[0003]

[Prior art]

 FIG. 6 shows a main part of a conventional expansion unit. In this conventional example, the expansion unit includes a pedestal portion 2 and a palm rest 3 which is provided on the front surface of the pedestal portion 2 so as to be pulled out, and the small electronic device 1 is held on the upper surface of the pedestal portion 2. It In FIG. 6, reference numeral 5 denotes a key top of the device 1.

It is possible to prevent the device 1 held on the cradle part 2 from easily falling off, or preventing only the device 1 from rising from the cradle part 2 when the front end of the device 1 is lifted. For this purpose, a pressing piece 4 for pressing the tip of the device 1 is integrally formed on the upper end of the palm rest 3.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, since the presser piece 4 is integrally formed on the palm rest 3 and the device 1 held on the pedestal part 2 has different thicknesses depending on the model, the presser piece 4 is different from the model. It has a drawback that it is necessary to prepare a plurality of types of palm rests 3 according to the thickness in advance.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a structure of an expansion unit capable of supporting a plurality of models.

[0007]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned object is to correspond to the embodiment and as shown in FIG. 1, a cradle part 2 for holding the small electronic device 1 on the upper surface, and a palm rest 3 that can be pulled out from the front surface of the cradle part 2. , And an inverted L-shaped presser piece 4 projecting from the upper end of the palm rest 3 so that the height of the palm rest 3 can be adjusted. The tip end of the small electronic device 1 on the cradle 2 is pressed by the presser piece 4. It is achieved by providing a structure of the expansion unit that prevents the falling of the expansion unit.

[0008]

[Action]

 In the present invention, the palm rest 3 includes a holding piece 4 for holding the front end of the device 1 placed on the upper surface from above. This presser piece 4 is height adjustable, absorbs the difference in thickness depending on the model, and improves versatility.

[0009]

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an expansion unit according to the present invention, which is formed by providing a palm rest 3 on a front surface of a main body portion 6.

A hard disk drive, a floppy disk drive 7, or various I / O printed circuit boards are housed in the main body section 6, and a cradle section for holding a small electronic device 1 such as a laptop computer. A connector 8 for connecting the device 1 is arranged at the rear edge of the device 2.

On the other hand, the palm rest 3 can be pulled out from the front end of the cradle part 2, and the device 1 is supported by the palm rest 3 and the cradle part 2 pulled out from the cradle part 2. Further, the palm rest 3 has a pressing piece 4 having an L-shaped cross section that projects upward, and presses the front end of the device 1 from above to prevent the device 1 from being detached or lifted. Has been made possible.

2 and 3 show the structure of the palm rest 3. The palm rest 3 is formed in a hollow shape and has an upper case 10 having a step portion 9 for locking the front surface and the rear surface of the device 1, and a lower case 11 connected to the upper case 10, and is formed in a hollow shape. The height of the presser piece 4 is held by the presser piece adjusting mechanism 12 that is stored.

The holding piece adjusting mechanism 12 includes an L-shaped fixing metal fitting 14 fixed to a boss 13 that is bulged in the lower case 11, a screw hole 15 in a rear wall 16 a, and opposite side walls 16 b and 16 b. Insert the holding piece 16 having a U-shaped cross section between the fixing piece 14 and the side edge of the holding piece 4, the hole 14a punched in the fixing piece 14 and the long hole 17 of the holding piece 4 to insert the holding piece 16 The fixing screw 18 is screwed into the screw hole 15.

The head portion 18a of the fixing screw 18 is exposed to the outside of the lower case 11, and by operating the head portion 18a, the holding piece 4 is fixed by bringing the holding piece 16 into the fixing metal piece 14 side. It In addition, it is desirable that a stopper be projected at an end of the fixing screw 18 so that the fixing screw 18 does not drop from the holding piece 16 when the fixing screw 18 is loosened. Further, the dimension a in the drawing is made smaller than the dimension b so that the holding piece 16 can be surely pulled into the fixing metal fitting 14 side by operating the fixing screw 18.

Therefore, in this embodiment, first, after pulling out the palm rest 3 from the main body portion 6 and mounting the device 1, the horizontal piece of the pressing piece 4 is pressed so that the upper surface of the front end of the apparatus 1 can be pressed. The device 1 is fixed by adjusting the protruding height of the piece 4 and then tightening the fixing screw 18.

FIG. 4 shows a second embodiment of the present invention. In this embodiment, a proper number of V-shaped notches 19, 19 ... Are provided on the side edge of the pressing piece 4, and the pressing piece adjusting mechanism 12 has its tip end aligned with the V-shaped notch 19. It is formed by a V-shaped lock piece 20. 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 side by a spring 21. Further, the lock piece 20 is provided with a button 22 on the side wall, and the button 22 is exposed from the lower case 11 to the outside so that it can be operated from the outside.

Therefore, in this embodiment, the button 22 is operated to release the locking between the lock piece 20 and the holding piece 4, and the holding piece 4 is pulled out upward, and then the holding piece 4 is placed on the upper surface of the machine 1. The device 1 is fixed only by pushing it down until it comes into contact with.

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