Provided is an electronic apparatus including a cooling fan and a cover configuring an outer wall of an air flow path and having a heat sink arranged therein, and effectively utilizing a frame as a member for heat radiation. A cooling fanis arranged on the opposite side of a circuit board across an upper frameand attached to the upper frame. The electronic apparatus includes a cover having a shape for covering the air flow path and defining a wall of the air flow path together with the upper frame. Heat sinksandare arranged on the inner side of the cover

Electronic apparatus

The inner edge of a holesurrounding the outer circumference of a first heat sinkincludes two edgesandthat are positioned on opposite sides to each other with the first heat sinktherebetween. An upper frame (shield)includes spring portionson one edge, which is in contact with the first heat sinkto push the first heat sinktoward the other edge. Further, the upper frameincludes, the other edge, a position determining portionto which the first heat sinkis pressed. According to the above electronic apparatus, it is possible to define the position of a metallic component by a shield covering a circuit board and to cause the metallic component and the shield to be in contact stably.

Provided is an electronic apparatus capable of also supplying sufficient air flow to a heat generating device other than the heat sink. An electronic apparatus includes: a cooling unit () including a heat sink (), and a cooling fan () for generating air flow for receiving heat of the heat sink (); an upper wall member () connected to the cooling unit () so as to form an outer wall defining an air passage continuous with the cooling unit (); and a power circuit () arranged in the air passage and serving as an object to be cooled.

An optically sampling device optically samples an optical analog signal using a sampled signal having a predetermined sampling frequency, and outputs control light having a pulse train of an optically sampled optical analog signal. A signal generating device generates a pulse train of signal light which is synchronized with the sampled signal. An optical encoding device optically encodes the pulse train of the signal light according to the control light, by using optical encoders each including nonlinear optical loop mirrors, and outputs pulse trains of optically encoded signal light from said optical encoders, respectively. An optically quantizing device performs optical threshold processing on the pulse trains of optically-encoded signal light to optically quantize them, by using at least one of optical threshold processors each of which is connected to each of said optical encoders and includes a nonlinear optical device, and outputs optically quantized pulse trains as optical digital signals.
