    摘要： Disclosed is an illuminating unit capable of effectively introducing light emitted from a light source into a light guide sheet to improve the brightness of light and emitting uniform color light. Light emitted from a light emitting diode of a light source unit is incident on a side surface of a light guide sheet. A spacer aligns the emission center of the light emitting diode with the center of the light guide sheet in the thickness direction thereof. The incident light travels in the light guide sheet and is then diffused in light emitting regions provided on the main surface of the light guide sheet. Then, the diffused light is emitted to the outside. In addition, light components emitted from a gap between the light emitting diode and the side surface of the light guide sheet or light components emitted from the upper surface of the light source unit to the outside are reflected to the light guide sheet by a cover member.

    摘要： A keyboard is constructed so that a ratio of a dimension between a first latching portion of a first lever and a pivotally supporting portion thereof to a dimension between this pivotally supporting portion thereof and a second latching portion thereof is equal to a ratio of a dimension between a first latching portion of a second lever and another pivotally supporting portion thereof to a dimension between this pivotally supporting portion thereof and a second latching portion thereof. Thus, when the key top descends, the second latching portions of the first and second levers are placed outside the first latching portions of the first and second levers. Consequently, reduction in thickness of a keyboard is achieved.

    摘要翻译： 键盘被构造成使得第一杆的第一闩锁部分和其枢转支撑部分之间的尺寸与其枢转支撑部分之间的尺寸与其第二闩锁部分之间的尺寸的比率等于 第二杠杆的第一闩锁部分和其另一个枢转支撑部分到其枢转支撑部分和其第二闩锁部分之间的尺寸。 因此，当键顶下降时，第一和第二杠杆的第二闩锁部分被放置在第一和第二杠杆的第一闩锁部分的外部。 因此，实现了键盘的厚度的减小。
