摘要： There is provided a surface light source device of side light type, which is not reduced in efficiency of illumination light utilization, even if the surface light source device is subjected to fringing such as to trim a luminant portion. For instance, a light shielding layer formed by coating black ink 21A, which absorbs illumination light, by means of printing is provided on a protection sheet 21 arranged as the outermost emission-side additional sheet. The light shielding layer absorbs and shields illumination light L1 tending to be transmitted through a peripheral edge portion of the protection sheet 12, and as a result, provides fringing. A reflective surface is formed by applying a silver tape 21B or the like to a surface facing the light guide plate 6. Since illumination light reflected by the silver tape 21B is used again inside the light guide plate 6, it is possible to avoid a reduction in efficiency of light utilization. The reflective layer may be narrower or wider than the light shielding layer, or may be equal in width to the light shielding layer at need. The reflective surface and the light shielding layer may be also formed on other components.

摘要： There is offered a battery charger for a portable electronic device that has a simple structure and is capable of detecting that the portable electronic device is connected to the battery charger. A first power supply line is connected to a positive terminal (+) of a rechargeable battery, while a ground line is connected to a negative terminal (−) of the rechargeable battery. An output transistor is connected between the first power supply line and a second power supply line. The output transistor is connected to a Vbus terminal of a USB connector through the second power supply line. A controller outputs a voltage of an H level to the Vbus terminal to detect a change in a voltage at the Vbus terminal, and judges whether the portable electronic device is connected to the USB connector based on a result of the detection. The controller turns the output transistor on when the portable electronic device is judged to be connected to the USB connector.
