とができる。2. Description of the Related Art In a conventional personal computer, a display unit is mainly a CRT in a desktop type and a backlit liquid crystal in a notebook type. Since the CRT and the liquid crystal with a backlight emit light by themselves, it is easy to confirm the display even if the operator works in a dark place. Even if the display unit is liquid crystal without a backlight, the liquid crystal display unit and the keyboard can be illuminated by attaching a light source to the liquid crystal display unit.

り確認を行うのは非常に困難である。However, since the keyboard, which is the input device of the personal computer, is supposed to be used in a bright place, it has a function of confirming the type of the keyboard key in a dark place other than the feel of a finger. Therefore, it is very difficult for the operator to visually confirm the keyboard in a dark place.

て視野を妨げるという問題がある。Further, when a light source is attached to the liquid crystal display unit, it is possible to visually confirm the keyboard in a dark place, but a large-capacity light source is required because it is necessary to illuminate the liquid crystal display unit and the keyboard. At the same time, when the liquid crystal part is equipped with a backlight, there is a problem that light is injected into the liquid crystal and rather obstructs the field of view.

The keyboard includes a light source for illuminating the keyboard and a cover for protecting the light emitted from the light source from irradiating other than the keyboard.

Illumination is performed to the extent that the key can be fully confirmed. The cover 3 prevents the light emitted from the light source 2 from being reflected on the display unit 4 such as a CRT or a liquid crystal display with a backlight and making it difficult to confirm the display. Further, the cover 3 prevents the light emitted from the light source 2 from directly entering the eyes 5 of the operator.

できる効果を有する。As described above, according to the present invention, by providing the light source for illuminating the keyboard and the cover for preventing the light emitted from the light source from irradiating other than the keyboard, the tactile sensation of the finger is obtained. This has the effect of visually confirming the keys of a personal computer in a dark place without relying on.
