Electronic apparatus

Abstract

The present invention relates to an electronic device such as a notebook-size personal computer and a portable terminal, and provides an electronic device having high visibility and of low cost. An electronic device includes a calculation unit and plural light sources. The calculation unit incorporates a keyboard disposed on a top surface of the electronic device and an electronic circuit (not illustrated) to perform calculation processing according to an operation of the keyboard. The plural light sources are arranged in a deep side and on both sides of the calculation unit, to illuminate thekeyboard in an obliquely inward direction. An LED having directivity may be used as the light sources.

Description

technical field [0001] The present invention relates to electronic devices such as notebook personal computers and portable terminals. Background technique [0002] Electronic devices such as notebook personal computers (hereinafter referred to as notebooks) and portable terminals are often used mainly under indoor light, and when these electronic devices are used in a dark place, the keyboard surface cannot be seen well, so There is a problem of inconvenient use. [0003] Therefore, a keyboard is disclosed that includes a light source for illuminating a keyboard portion of a personal computer in order to improve the visibility of the keyboard in a dark place (for example, refer to Patent Document 1). Moreover, the following lighting device is also disclosed, which has a light source that outputs invisible light, and at the same time, a substance that outputs visible light by irradiation of the invisible light output by the light source is provided on each key of the keyboa...

Problems solved by technology

[0006] However, in the keyboard disclosed in the above-mentioned Patent Document 1, a light source is provided on the back side of the keyboard. Since there is a fear that the light irradiated from the light source may enter the operator's eyes and cause glare, a protective cover is provided so that the light from the light source does not Directly enters the operator's eyes. Although the light cannot directly enter the operator's eyes by setting the protective cover, there is a problem that the reflected light from the keyboard enters the operator's eyes.

[0007] Moreover, in the keyboard lighting device disclosed in the above-mentioned Patent Document 2, since invisible light is used, there is a problem that when printing characters on the keyboard, it is necessary to use a substance that reacts to invisible light for printing, resulting in an increase in cost.
