Abstract

PROBLEM TO BE SOLVED: To suppress the power consumption and prolong the life of a battery by providing an indicator which illuminates by using light, collected by an optical fiber through the sliding of a slide mechanism, as a light source. SOLUTION: When a device 1 is connected to an external interface 21, the slide mechanism 3 fitted to the external interface 21 slides to, align one end of the optical fiber 7 with the indicator 4, which illuminates with the light collected by the optical fiber 7. The light emitted by the fluorescent tube of a back light 6 is gathered to a light guide plate, one end of the optical fiber 7 is arranged nearby a reflection body to gather the light, which is used as the light source of the indicator 4. Thus, the light of the back light 6 of an LCD 5 is used as the light source to make the indicator 6 illuminate without requiring any dedicated light source, so the power consumption is reduced to prolong the life of the battery.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing device, and more particularly to a portable information processing device having a backlit LCD and an indicator for displaying the presence or absence of an external device.

[0002]

2. Description of the Related Art In a conventional portable information processing apparatus, as shown in FIG. 4, when a device 1 is connected to an external interface 21 of a data processing unit 2, a slide mechanism 3 slides and a switch 170 is turned on. However, since the indicator 4 is lit by being supplied with power from the power source 171 to the indicator 4, power consumption of the indicator 4 is increased, and battery power consumption increases in a portable information terminal driven by a battery due to increase in current consumption. Is reduced.

[0003]

As described above, the conventional portable information processing device requires the power source for the indicator 4 to increase the power consumption, and the portable information terminal driven by the battery consumes less current. There is a problem that the battery life is reduced due to the increase.

Therefore, it is an object of the present invention to provide a portable information processing device which suppresses power consumption and increases battery life.

[0005]

In order to solve the above-mentioned problems, a portable information processing apparatus of the present invention is provided with an external interface for processing data and a data processing unit for processing the data. LCD that displays the recorded data
A backlight for illuminating the LCD, an optical fiber for arranging one end of the backlight to collect light, and another end of the optical fiber for connecting the device to the external interface. It is characterized in that it is constituted by a slide mechanism for performing a slide with and an indicator which is turned on by using the light condensed by the optical fiber as a light source by the slide of the slide mechanism.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a portable information processing device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a portable information processing apparatus according to an embodiment of the present invention.

FIG. 2 is a configuration diagram (A) and a sectional view (B) of a backlight of a portable information processing device according to an embodiment of the present invention.

FIG. 3 is a schematic diagram (A) of turning off the indicator and a schematic diagram (B) of turning on the indicator of the portable information processing device according to one embodiment of the present invention.

As shown in FIG. 1, a portable information processing apparatus according to an embodiment of the present invention is provided with an external interface 21, a data processing unit 2 for processing data 22, and a data processing unit 2 for processing the data. LCD 5 that displays the displayed data
The backlight 6 for illuminating the LCD 5, the optical fiber 7 for arranging one end of the backlight 6 to collect light, and the other end of the optical fiber 7 for installing the device 1 in the external interface 21. It is composed of a slide mechanism 3 that slides by being connected, and an indicator 4 that lights up with the light condensed by the optical fiber 7 as a light source by the slide of the slide mechanism 3.

Further, as shown in FIGS. 2A and 2B, the backlight 6 of the portable information processing apparatus according to the embodiment of the present invention has a fluorescent tube 61 for emitting light and the fluorescent tube 61.
It is composed of a reflector 62 that reflects the light emitted from and a light guide plate 63 that collects the light reflected by the reflector 62.

Next, the operation of the portable information processing device according to one embodiment of the present invention will be described with reference to the drawings.

In the operation of the portable information processing apparatus according to the embodiment of the present invention, as shown in FIGS. 2A and 2B, the light emitted from the fluorescent tube 61 of the backlight 6 is reflected by the reflector 62. The light is collected by the light guide plate 63, one end of the optical fiber 7 is arranged in the vicinity of the reflector 62 to collect the light, and the collected light serves as the light source of the indicator 4, and the external interface 2
When the device 1 is connected to 1, the slide mechanism 3 attached to the external interface 21 slides so that one end of the optical fiber 7 coincides with the position of the indicator 4, as shown in FIG. The indicator 4 is turned on by the light collected by the optical fiber 7.

Further, the device 1 uses the external interface 2
When not connected to 1, the slide mechanism 3 attached to the external interface 21 does not slide, as shown in FIG. 3A, so that one end of the optical fiber 7 does not coincide with the position of the indicator 4. Indicator 4
Does not light.

[0015]

As described above, according to the portable information processing apparatus of the present invention, the light of the backlight of the LCD is used as the light source, so that the indicator is turned on without the need for a dedicated light source. This has the effect of suppressing power consumption and increasing battery life.
