    Abstract: A portable electronic device in which microswitches (12) controlled by operation buttons (11) are mounted on one side of a printed circuit board (13), and circuit elements accommodated in BGA packages (14), (15) and (16) are soldered on the other side of the printed circuit board. In the portable electronic device, a shield wall (22) for surrounding the BGA packages (14), (15) and (16) is mounted on the printed circuit board (13), a first protrusion portion (18b) for holding down the shield wall (22) on the printed circuit board (13) is protruded from a case (18) of the portable electronic device (10), and second protrusion portion (18c) for holding down surfaces of the BGA packages (14); (15) and (16) on the printed circuit board (13) is protruded from the case (18) of the portable electronic device (10). With such a construction, the BGA packages are prevented from being peeled off from the printed circuit board (13). Further, even when the push buttons are frequently depressed in playing a game, the soldering parts of the BGA packages mounted on the back side of the operation button can be maintained in good conditions.

    Abstract: A determination is first made on the presence or absence of input of an advance application number as advance application information (S2). Here, when it is determined that the input is present (Y in S2), the advance application number and a reception number as identification information for identifying a wireless tag handed to an attendee, are registered as entrance information in an attendee management table being a database in association with each other (S7 and S14). Meanwhile, when it is determined that the input is absent (N in S2), the reception number is registered as entrance information in the attendee management table (S12 and S14). Hence, it is made possible to hand IC tags to all attendees promptly to complete an entrance reception in a short period of time, and therefore it is possible to smoothly perform the entrance reception.

    Abstract: This invention relates to a transmissive liquid crystal display including a light source (BL), a reflective linearly-polarizing layer (Pr1), a birefringent layer (A) having specific optical properties and specific retardation properties, a light source-side absorptive linearly-polarizing layer (P1), a liquid crystal cell (LC), and a viewer-side linearly-polarizing layer (P2) which are arranged in this order. In the transmissive liquid crystal display of the invention, light leakage is suppressed in oblique directions so that black brightness can be reduced. A reduction in contrast in the normal direction can also be suppressed, which is caused by the distribution of light to the normal direction.

    Abstract: An apparatus includes a two-sided prism sheet, and an optical path conversion unit with linear prisms. Each apex angle of the prisms increases the closer the linear prism is formed to the center in the light guide direction, and when a pair of inclined surfaces of each of the prisms has a first inclined surface and a second inclined surface, an inclination angle of the second inclined surface is larger than the one of the first inclined surface. Among the prisms, inclination angles e1 and e2 of a pair of inclined surfaces of a linear prism formed closest to the center and an inclination angle c of the first inclined surface and an inclination angle d of the second inclined surface of a linear prism formed closest to the side end surfaces at which the light sources are disposed satisfy a relationship 2×c
