A device for indicating a device status includes a plurality of light guides including a first end for receiving light and a second end for displaying light, respectively; a plurality of light emitting elements arranged to face to each of the first ends; and a light shield arranged between the light guides and extending between light emitting elements, the light shield shielding light from the light emitting elements.

Status indicator

There is provided a multi-layer printed wiring board that can perform impedance control, concurrently maintaining the flexibility of a flexible portion with one or more signal lines. Such a multi-layer printed wiring board includes a plurality of rigid board units; and a flexible board unit, connecting outer layers or inner layers of the plurality of rigid board units and extending over the outer layers or the inner layers of the plurality of rigid board units. The flexible board unit includes a signal layer sending signals between the plurality of rigid board units; ground layers sandwiching the signal layer; and intermediate layers each interposed between the signal layer and one of the ground layers.

Multi-layer printed wiring board, electronic device, and fabrication method of electronic device

A heat radiator capable of thermally connect to a heat element includes a pair of heat conducting plates conducting heat from one side surface to other side surface of the heat conducting plate, respectively, the pair of heat conducting plates having a space between each of the heat conducting plates; and a radiation fin arranged between the pair of heat conducting plates, having elastic characteristics between the pair of heat conducting plates, and radiating heat from the heat conducting plate to the space.

Heat radiator

A connector for electrically connecting with a first circuit board and a second circuit board, the connector includes a female connector and a male connector. The female connector includes a housing, a moveable side electrode capable of moving in the housing and an elastic member biasing the moveable side electrode, the moveable side electrode having a recess. The male connector includes a projection with a tip end being fitted into the recess of the moveable side electrode.

Connector

A heat radiating apparatus includes a radiator adhering to an electronic component mounted on a circuit board via an elastic member provided on the circuit board so that the electronic component is cooled. The radiator includes a plurality of projection parts, the elastic member includes an engaging part configured to engage the projection part and a radiator insert hole forming part where the radiator is inserted, and a pushing force is applied from the elastic member to the radiator by rotating the radiator so that the projection part is engaged by the engaging part, and thereby a bottom surface of the radiator is adhered to the electronic component.

Heat radiating apparatus of electronic component

An electronic apparatus includes an optical connector adapting unit to which optical connectors of external optical fibers are connected. The optical connector adapting unit includes a plurality of optical connector adapters which are diagonally arranged on the front side of the apparatus. The optical connectors of the external optical fibers are diagonally detachable from the optical connector adapters. In this electronic apparatus, a large number of optical connectors of optical fibers can be connected and arranged in a restricted space.

Electronic apparatus

A transmission apparatus with flexible structure for introducing external cables that controls signal transmission efficiently. A cable connector for introducing a cable from the outside is fixed on a sub-printed circuit board. A main printed circuit board has a guide rail along which the sub-printed circuit board can be inserted reversely to change the direction from which the cable is introduced at the time of the sub-printed circuit board being housed. An enclosure has ducts for bunching cables. Transmission units are mounted in the enclosure.
