Patent ID: 8638569

Claim:
An electrical apparatus comprising: a first circuit board including an image sensor, a first connector, and a plural pair of first differential signal patterns transmitting differential signals from the image sensor to the first connector; and a second circuit board including an image processor, a second connector, and a plural pair of second differential signal patterns transmitting differential signals from the second connector to the image processor; wherein the first connector is connected to the second connector such that the differential signals output from the image sensor are input to the image processing circuit via the plural pair of first differential signal patterns and the plural pair of second differential signal patterns, wherein the second connector includes a plurality of terminals arranged in line on a first and a second sides of the second connector along a longitudinal direction of the second connector, wherein the second connector is located such that a shorter side of the second connector faces to the image processor, wherein at least two pairs of second differential signal patterns extend through a region between the plurality of terminals arranged on the first side of the second connector and the plurality of terminals arranged on the second side of the second connector in the same direction, wherein a first pair of second differential signal pattern extending through the region is connected to the plurality of terminals arranged on the first side of the second connector, and wherein a second pair of second differential signal pattern extending through the region is connected to the plurality of terminals arranged on the second side of the second connector.
