A cable connector for balanced transmission is disclosed. High-voltage terminal 11 and low-voltage terminal 12 are provided in battery 6. 01 to 10 \u03bcm, and has a porosity of 30 to 85%, the composition constituting the porous layer has a glass transition temperature of 20\xb0 C. Further, the biasing member 18 is adapted to apply a biasing force to the pressing roller in a direction Y intersecting with an axis X connecting the respective center positions of the fixing roller 12 and the pressing roller 16. A recognizing unit is also included that is configured to recognize lengths in the main scanning direction and the sub scanning direction of the manuscript, based on a displacement of the manuscript sensor from the reference position. In a closed configuration, the gates define a channel that narrows in the conveying direction to trap the article.
