Therefore, except for the liquid crystal display unit incorporated in the lid, the control circuit unit, power supply circuit unit,
The layout was considered so that the stacking height of each of the unit parts, such as the keyboard, function keys, and the internal battery, was approximately the same as the stacking height of the external storage device arranging part that affected the height of the main unit. Therefore, the height of the main body can be reduced and the portability can be improved.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a usage state diagram of a portable information processing device such as a notebook type Japanese word processor or a personal computer according to an embodiment of the present invention.

Reference numeral 1 denotes a keyboard as an input device. A liquid crystal display device 2 for displaying an input from the keyboard 1 is incorporated in an openable and closable lid 3, and has a structure in which the front surface is covered by a liquid crystal panel 4. Reference numeral 5 denotes an external storage device comprising a magnetic disk drive for recording the input and edited information, which is interposed between the lower case 6 and the upper case 7. A function key 8 is provided behind the keyboard 1 of the upper case 7 so as to be laterally juxtaposed with the external storage device 5. When the function keys 8 are integrally formed with the keyboard 1 of the input device and have the same structure, if the keyboard 1 and the external storage device 5 are arranged side by side with respect to the depth direction to reduce the thickness, the dimension in the depth direction increases. In some cases, a separation structure is required.

On the other hand, a control board 9 for controlling the entire apparatus is arranged below the keyboard 1 for inputting characters and numerals and the function keys 8 as shown in FIGS. Below the keyboard 1, there is provided a control circuit section 10 composed of a component having a relatively low height h. The rear part of the keyboard 1 is a power supply circuit section 11 which requires a relatively high mounting component height H, and the control circuit section 10 and the power supply circuit section 11 are formed on a single substrate.

Further, on the control board 9 below the function keys 8 separated from the keyboard 1, the keyboard 1 and the function keys 8 are provided.

Is provided.

Reference numeral 15 denotes a cartridge such as an IC card provided at an end of the control board 9, and reference numeral 16 denotes an internal battery for enabling operation of the main body when the AC adapter is not used. Further, hinge mechanisms 17 are provided at both ends of the rear part of the lower case 6 so that the main body and the liquid crystal display 2 can be connected and opened freely.

Here, the function key 8 separated from the keyboard 1 to reduce the depth of the main body will be described.
As shown in FIGS. 4 and 5, since the connector 12 is arranged below the function key 8, the function key 8 also needs to have a thin structure different from the structure of the keyboard 1. That is, a key top 19 in which each key top is continuously formed integrally is provided inside a frame 18 to be attached to the main body, and a lower portion of each key top 19 is made of a spring material such as a phosphor bronze plate. A reversing spring 20 and a membrane switch 21 are further disposed below the reversing spring 20, and a support bracket 22 and a frame 18
The thickness is reduced by manufacturing the convex portion 23 by heat-sealing. In addition, the key top 19, the reversing spring 20, and the like are abolished in place of the configuration of the function key 8 described above.
It is also possible to configure so that the membrane switch 21 is directly operated.

Next, the stacking dimensions will be described. The height dimension of the main body is dominated by the stacked dimension of the external storage device 5, the lower case 6, and the upper case 7, and therefore, the control circuit section 10, power supply circuit section 11, keyboard 1, The layout location of each unit component such as the function key 8 and the internal battery 16 is taken into consideration so that the stacking height of the arranging portion is substantially equal to the stacking height of the arranging portion of the external storage device 5. is there.

The arrangement of each unit component for reducing the thickness of the main body has been described above. However, in order to reduce the thickness and weight of the entire main body, the thickness and weight of the liquid crystal display device 2 must be reduced. is there. Next, the structure will be described with reference to FIGS. 7, 8, 9, and 10. FIG.

Reference numeral 24 denotes a liquid crystal display section, in which liquid crystal is sealed in a gap formed between the upper LCD glass 25 and the lower LCD glass 26, and seals the space between the upper LCD glass 25 and the lower LCD glass 26. Formed and each LC
An upper polarizer and a lower polarizer are adhered to the surface of the D glass. Around the LCD glass, a common-side substrate 28 and a segment-side substrate 29 on which a COB (Chip On Bord) 27 is mounted for thinning are arranged, and the electrodes of the LCD glass and the heat seal are connected to each other. Further, a liquid crystal control substrate 30 for controlling both substrates is arranged in a plane on the side surface of the LCD glass, and the liquid crystal control substrate 30 is connected to the common side substrate 28 and the segment side substrate 29 by a flexible harness 31. .

On the other hand, the lower LCD below the liquid crystal display section 24
A light guide plate 32 made of a material such as an acrylic resin is provided on all surfaces of the glass 26 so as to face each other.
The light from No. 3 is evenly and efficiently guided to the entire surface of the liquid crystal display unit 24. Reference numeral 34 denotes an inverter board for lighting the cold cathode tubes, which is provided in parallel with the liquid crystal control board 30 in a plane, and is configured to be supplied with power by flexible cables 35 connected to the control board 9 on the main body side.

The above-described liquid crystal display unit 2 arranged in a plane.
4. When assembling the common-side substrate 28, the segment-side substrate 29, the liquid crystal control substrate 30, the inverter harness 34, and the like to the resin-molded LCD frame 36, a notch 37 is formed at the end of the light guide plate 32 and A receiving portion 38 is formed on the above-described LCD frame 36 to form a laminated assembly structure, and is fixed with a stopper 40 via a protective cushion 39 attached to the lower LCD glass 26.

With this structure, it is possible to make the LCD glass thickness and the stacking height of the light guide plate 32 which are the minimum necessary for the liquid crystal display device 2 into a thin unit.

The liquid crystal display device 2 includes a lid 3 and a liquid crystal panel 4.
By incorporating it in between, it is possible to reduce the thickness and weight not only of the main body but also of the liquid crystal display.

[0021]

According to the present invention, the stacking dimensions of the external storage device 5, the lower case 6, and the upper case 7 are dominant with respect to the height. Unit 10, power supply circuit unit 11, keyboard 1, function key 8,
Since the placement location is considered so that the stacking height of each unit component such as the internal battery 16 is substantially the same as the stacking height of the mounting portion of the external storage device 5, the height is minimized. It becomes possible to hold down to the limit.

Further, the liquid crystal display unit 2 also has a minimum required upper L
The LCD frame 36 is formed by the thickness of the CD glass 25 and the lower LCD glass 26 and the lamination height of the light guide plate 32, and is arranged in a plane, so that the entire body can be made thinner and lighter, and excellent in portability. It can be.
