According to an embodiment of the present invention, there is provided a magnet screen device, comprising a casing having an opening, a roll rotatably placed in the casing, and a magnet screen, the magnet screen being configured to be wound on the roll during a storage of the magnet screen and configured to be pulled out from the opening of the casing and to be attached to an installation surface upon an use of the magnet screen, wherein the magnet screen device further comprises a bar part at a region where the opening is provided, and wherein the bar part is configured to be capable of contacting the magnet screen at the region where the opening is provided.

A magnetic eraser can be used for erasing markings drawn on a magnetic sheet. The magnetic eraser includes a housing with a magnet placed in the housing. The magnetic eraser also includes a first magnetic body placed between a first surface of the housing and the magnet. The first surface of the housing can provide a first erasing surface.

A magnetic erasing device including a magnet that includes an S pole and an N pole extending along an axial direction of the magnet, and a rotation mechanism for rotating the magnet in a housing around an axis of the magnet, wherein lines of magnetic force generated around the axis of the magnet during rotation of the magnet are designed to be applied to magnetic particles in the microcapsules to erase a visible image on a magnetic panel when the axis of the magnet is spaced from a surface of the magnetic panel by a predetermined distance.

The present disclosure generally relates to display systems, display devices, and methods of making and using them. Some exemplary display systems are capable of attaching a display device to a computer monitor. The exemplary display systems sought to create improved display systems and devices capable of displaying information to a user and attaching to a computer monitor and/or lagre format electronic display.

A reusable writing surface is provided having a board having a front side and a rear side. A plurality of magnets is positioned on the rear side, wherein the plurality of magnets is configured to magnetically attach to a plurality of removable magnetic legs. The plurality of magnets are positioned such that the plurality of removable magnetic legs are configured to stand the reusable writing surface in either a vertical orientation or a horizontal orientation depending on which magnets of the plurality of magnets each magnetic leg attaches.

Superior usability is provided and the degree of freedom in terms of use is enhanced.

A plurality of link members A1 and A2 include at least one of linear edges A12 and A22 at the peripheral edge of a facing surface A10 or A20 that faces in a folded state. At least one of the adjacent link members A1 and A2 is a magnet, and the other is a material attracted by the magnet. A link body A is formed of the link members A1 and A2 that are linked by the attracting force due to the magnetic force of the link members A1 and A2, of which the linear edges A12 and A22 are aligned.

A magnetic erasable writable material for large format applications is disclosed, and includes a cast polyvinylchloride film with a mount surface opposite an etched receiver surface. Also incorporated is a transparent polyester film that has a marking side with a first predetermined hardness and an opposite seal side, laminated to the receiver surface. The marking side includes a clear superstrate that has a second predetermined hardness and applied to the marking side of the polyester film to lower its surface energy. The receiver surface is treated to have a surface energy adjusted to enable improved adherence of printed and preformed graphic elements, which are encapsulated when laminated between the PET film and receiver surface. The superstrate includes a perfluoropolyether, a polyurethane, an acrylated polyurethane, and/or an acrylate resin to harden the material.
