Abstract: An electronic apparatus includes a main body having a first surface having a display surface, a second surface opposite to the first surface, and a first support disposed between the first surface and the second surface being capable of contacting with a put-on surface; a stand member attached to the main body having a second support being capable of contacting with the put-on surface; and a hinge unit having a hinge rotatably supporting the stand member against the main body between a first rotational position for standing up the main body on the put-on surface and a second rotational position for laying the main body over the put-on surface, and an elastic member disposed at the hinge for adding a rotational force from a second rotational position side to a first rotational position side.

Abstract: An information processing apparatus includes a main body portion, a support portion, and a communication portion. The main body portion includes a display portion. The support portion supports the main body portion and forms a space below the main body portion in which information equipment connectable to the main body portion can be accommodated. The communication portion is provided to the support portion and performs communication with a noncontact-type communication medium.

Abstract: Disclosed herein is a light receiving apparatus, including: a light receiving section including a light receiving element; a transparent part; and a light guiding part inserted in the groove; the groove having, on the front face side, a side face formed as an arcuately curved face convex toward the front face side and having the same shape in any cross section perpendicular to the front face and also to the depthwise direction of the groove; the light guiding part having a side face opposing to the side face of the groove on the front face side and formed as an arcuately curved face which is convex toward the front face side in a state wherein the light guiding part is inserted in the groove and which has the same shape in any cross section perpendicular to the front face and also to the depthwise direction of the groove.

Abstract: A housing having openings for exposing the operation surfaces of a peripheral component interconnect (PCI) expansion card and a communication and network riser (CNR) expansion card to the outside at its front surface and at its back surface, respectively. A motherboard, which is incorporated in the housing, has multiple connectors arranged at specific intervals. The PCI expansion card has a PCI card electrode and is inserted into and connected with one of the connectors of the motherboard. A CNR expansion card has a CNR card electrode and is inserted into and connected with another one of the connectors of the motherboard. The PCI expansion card and the CNR expansion card are attached to the corresponding connectors in the motherboard, with the electronic-parts-implementing surface of the PCI expansion card and the electronic-parts-implementing surface of the CNR expansion card facing each other.
