An electronic apparatus is provided. The apparatus includes a first body and a second body configured to move with respect to each other, a rollable display, a roller rotatably supported in the first body, wherein a first end portion of the rollable display is fixed to the roller and the rollable display is wound around an outer circumference of the roller, and a tensile force application portion configured to apply an elastic force to the roller to rotate in a direction to wind the display, the tensile force application portion rotating with the roller, in which, as the first body and second body move with respect to each other, the rollable display is wound around the roller to be accommodated in the first body or is released from the roller to expanding between the first body and the second body in a length direction.

The invention relates to a device comprising a multilayered structure with a first portion and a second portion wherein the first portion is conceived to be rolled about a first roller, said device comprising a second roller for receiving the second portion for at least partially counteracting the effects of mechanical strain induced in the multilayered structure upon said rolling. The first roller is rotated in a first direction, whereby the second roller is rotated in a second direction. Preferably, the diameters of the first roller and the second roller are equal. Alternatively, the edge portions A, B of the multilayer structure are suitably interconnected by stoppers for preventing creeping.

A scrolling system for scrolling a printed roll of media includes a mechanical scrolling apparatus and a user interface device. The mechanical scrolling apparatus includes a first winder for placing the printed roll and from which first winder the printed roll is unwindable, and a second winder for winding up the printed roll unwound from the first winder. At least one winder of the first and second winder is drivable by a motor. An unwound area is a piece of the printed roll that is unwound from the first winder and not yet wound up on the second winder. The user interface device is configured to receive a selection of a part of a digital representation of images printed on the roll. Upon receiving a selection of the part of the digital representation of the images printed on the roll by means of the user interface device, the motor is activated in order to scroll the printed roll by means of the two winders until a piece of the printed roll arrives in the unwound area, which piece of the printed roll corresponds to the selected part of the digital representation. A method to be applied by the scrolling system is also disclosed.
