Description

The present invention relates to a fixed or foldable device,

  to support a flexible moving band that winds and unwinds around two rotating cylindrical axes mounted in parallel to allow the

  reading of any printed or manuscript sign on both exposed faces of the moving mobile band.

  The reading of these tapes has already been envisaged by devices comprising a parallelepiped-shaped casing, comprising a rigid window or a reading table, with only one face of the mobile band discovered. These devices are bulky, not very ergonomic, unattractive and design, industrialization and relatively complex use.

  The device according to the invention - thanks to its variation in size, the discovery of the two faces of the moving band, its simplicity and lightness, its ergonomics, its maneuverability and compactness, as well as the possibility of manufacturing with materials such as wood, hemp, plastic, aluminum, cardboard or any other material overcomes these disadvantages.

  The present device comprises two cylindrical housings, mounted in parallel and connected to each other by means of fasteners and / or joints with fixed or collapsible segments, lockable in the open position. The foldable segments are either composed of one or more detent hinges placed between each of said segments, or telescopic, or hinged according to any other system. Said segments are connected to the housings by fasteners and / or joints located below and / or above the longitudinal slot of entry and exit of the mobile band. The user can thus move away from each other, said cylindrical housings, and discover on both sides a variable portion of the moving band when the device is in read position.

  Each housing receives one of two hollow cylindrical axes mounted in parallel around which is wound the moving strip and thus ensures the protection and the scrolling of the moving band by rotation of the hollow cylindrical axes.

  Scrolling of said strip is ensured by the coupling of each of the hollow cylindrical shafts to a manual and / or motorized drive member. At least one drive member is inserted into each of the hollow rotary cylindrical axes through at least one rotational bearing consisting of an orifice in the bottom and / or top of the two cylindrical housings.

  Each part of the mobile strip is visible on its two faces as it passes, stretched between the two longitudinal slots in each of said cylindrical housings to ensure the entry and / or exit of the moving band which winds and takes place alternately around its two cylindrical emitter and / or receiver axes.
