Abstract: A device for holding a photoreceptor sheet onto a drum of an electro-photography printing device comprises first and second holding surfaces that are configured to hold an edge of the photoreceptor sheet from opposite directions by pressing against the sheet in a substantially perpendicular direction with respect to the surface of the sheet, wherein at least the second holding surface is pre-loaded.

Abstract: A carrying device comprising a rigid elongate yoke, extending between two distal ends, a clamping member adapted for engagement with the yoke member to clampingly fix the device on a supportive member of a backpack. At least both ends of the yoke member laterally project from the supportive member and each of the ends is formed with at least one strap-engaging element for connecting thereto a strap to support equipment. When the backpack is carried over the shoulders of a wearer, the equipment/gear hangs down in front of the body of the wearer.
