Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notebook personal computer, and more particularly to a notebook personal computer in which an LCD filter is installed and stored.

[0002]

2. Description of the Related Art Conventionally, in a desktop type personal computer,
CRT (display unit) to reduce operator eye strain
With respect to this filter, a method of mounting another product (CRT filter) is used. For example, JP-A-63-28
Japanese Patent Publication No. 7883 describes a method in which a hole is formed in the front of a CRT screen and a filter is attached to the hole. Japanese Patent Application Laid-Open No. 3-28880 discloses a method in which a groove is formed in an upper portion of a CRT and a filter is inserted therefrom.

[0003] However, in a notebook personal computer, when the personal computer is not used or when the personal computer is carried, L
CD (Liquid Crystal Display)
y: Liquid crystal display) Since the panel (display section) is closed, the above-described method of attaching a filter to the front of the LCD panel cannot be used. Alternatively, it must be removed each time the LCD panel is closed.

[0004]

In a conventional notebook-type personal computer, the LCD panel is usually closed when not in use. At that time, if a separate LCD filter is mounted on the front of the LCD panel, the LCD panel is completely closed. Therefore, there is a problem that a separate LCD filter cannot be mounted on the front surface of the LCD panel of the notebook computer.

Alternatively, the LCD filter may be damaged if it is not removed. Therefore, each time the LCD panel is closed, it is necessary to remove a separate LCD filter from the upper part of the LCD of the notebook computer.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an LCD filter for reducing the eye strain of an operator of a notebook personal computer, which can be mounted on the front of the LCD panel.
It is an object of the present invention to provide a notebook personal computer with a built-in LCD filter capable of closing a panel.

[0007]

In the notebook personal computer of the present invention, the LCD filter is housed in the take-up portion on the left side of the LCD panel of the notebook personal computer, and can be set when used by an operator. . L with the LCD filter still set
When the CD panel is closed, the LCD filter automatically returns to the winding section.

The LCD filter is set by the operator of the notebook computer moving the slide lever attached to the LCD filter to the right along the slide rail as necessary.

The LCD filter is automatically wound by the spring mechanism of the winding section when the slide lever is pressed or when the reset button is pressed by closing the LCD panel.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a notebook personal computer according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view of the notebook personal computer of FIG. It is. Referring to FIGS. 1 and 2, this embodiment can be divided into a winding unit 2 and a filter unit.

The take-up portion is constituted by a spool 8 using a plastic material and a mainspring 9 using a metal having spring properties.

The filter section comprises an LCD filter 1 and a slide lever 4 attached to the tip of the LCD filter. The slide lever 4 is preferably made of a plastic material because the operator may directly touch the slide lever.

The spool 8 and the mainspring 9 are mounted on a fixed shaft 19 of the LCD base 11 on which the LCD unit 10 is mounted.

The slide lever 4 is attached to the end of the LCD filter 1 and is locked to the LCD cover 12 when the LCD filter 1 is set.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIGS. FIG.
FIG. 4 is a detailed view of a D filter winding section, and FIG. 4 is a detailed view of a release lock section.

The LCD filter 1 is pulled out from the winding unit 2 by an operator moving a slide lever 4 attached to the tip thereof along a slide rail 5. When completely pulled out, the lock portion 13 of the slide lever 4 falls into the lock hole 14 of the LCD cover 12 and is held.

When the LCD panel 3 is closed, the reset button 6 on the top cover 7 pushes the slide lever 4 in the direction D, so that the lock portion 13 of the slide lever 4 comes off the lock hole 14 of the LCD cover 12 and is wound. Taken. When the operator presses the slide lever 4 because the LCD filter 1 is not necessary, the LCD filter 1 is similarly wound.

Further, since the LCD filter 1 moves in parallel, the projection on the upper part of the slide lever 4 fits into the groove (guide) of the LCD cover 12 and moves. Concerning joining of the LCD filter 1 and the slide lever 4, it is conceivable that a protrusion is made on the slide lever 4 using a plastic material, and the protrusion is put into the hole of the LCD filter 1 and welding or an adhesive is used.

Next, regarding the attachment of the LCD filter 1 and the winding unit 2, the spool 8 of the winding unit 2 uses a plastic material, and the welding or the adhesive may be used in the same manner as described above. Conceivable.

Therefore, the LCD filter 1 is wound around the spool 8 by rotating the spool 8.

As means for rotating the spool 8, the spring property of the mainspring is used. As shown in FIG.
The spool 8 and the mainspring 9 are incorporated in a fixed shaft 19 of the LCD base 11. The inner end of the mainspring 9 is fitted on the fixed shaft 19. The outer end is fitted in the inner groove of the spool 8.

By pulling out the LCD filter 1,
The spool 8 rotates in the B direction. The rotation of the spool 8 causes the mainspring 9 to similarly rotate in the B direction. By this rotation, a force for returning to the C direction is stored in the mainspring 9.

When the slide lever 4 is disengaged from the lock hole 14 of the LCD cover 12, a force (rotational force) returning to the spring 9 rotates the spool 8 in the direction C to wind up the LCD filter 1.

For the spool 8, it is preferable to use a plastic material. It is preferable to use the same material (ABS material, polycarbonate material) for the notebook personal computer.

The diameter is determined by the size of the LCD unit, but for a size of 12.1 inches, LC
In order for the D filter 1 to be wound, the spool 8 needs to rotate four times, and is considered to have a diameter of 22 to 25 mm.

The material of the spring 9 is 0.1 mm
It is preferable to use a degree of spring phosphorus or stainless steel for spring, and to perform tempering after quenching to maintain strength.

Next, a second embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 5, a method of forcibly rotating the spool 8 using a motor 15 as a means for winding the LCD filter 1 can be considered. When a close-off switch, which is pressed when the LCD panel is closed, works on a conventional notebook PC, the motor rotates,
The spool 8 connected via the gear 16 rotates.

Next, a third embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 6, the spool 8 has an LCD
When the filter 1 is pulled out, it rotates in the F direction. Due to the rotation, the rack 17 connected to the gear moves in the G direction. A spring 18 is attached to the rack 17 between the rack 17 and the LCD base 11.
7 moves in the G direction, the spring 18 expands, and a force for returning the rack 17 to the H direction is generated.

When the lock of the slide lever 4 is released, the rack 17 moves in the H direction,
And the LCD filter 1 is wound up.

[0033]

As described above, according to the present invention, the LC
The D filter is built into the notebook computer, and the LCD filter can be set on the LCD panel as needed. When the LCD panel is closed, the LCD filter automatically returns to the winding section.
There is no need to attach a separate LCD filter, and the LCD panel can be easily closed.
