    摘要： An image sensor unit, and method, used in an image reading apparatus such as a facsimile machine, image scanner, copier machine, includes a feeding path through which a feeding document, having an imaged to be read, is passed. In the feeding path, the feeding document is passed over a contact glass through which a light from a light source illuminates an image on the feeding document. Reflected light is then detected with a detection and converted into image data. However, unless appropriate measures are taken, the integrity of the image data is subject to corruption as a result of electric noise generated from discharging of excess charge developed on the contact glass when the feeding sheet moves along side of the contact glass. The present image sensor includes a method and mechanism for passing the accumulated charge to ground, thereby avoiding the possibility of electrical discharge and associated electrical noise. Furthermore, the present image sensor includes a transparent thin film made of a material that prevents the accumulation of excess charge.

    摘要： A separation conveyance device comprises: a separation unit that includes a first roller feeding a conveyance object, and a load unit applying a load to the fed conveyance object, and separates one conveyance object from conveyance objects; a second roller that conveys the fed conveyance object; a driving unit that causes a motor to rotate the first roller at a first linear speed and the second roller at a second linear speed higher than the first linear speed; a connection unit that cuts off the motor's power from the first roller when first load torque toward a rotation direction of the first roller is equal to or larger than a certain value; a detection unit that detects second load torque in the direction opposite to a rotation direction of the motor; and a determination unit that determines a separation state of the conveyance object based on the second load torque.
