Abstract
PURPOSE: To prevent a paper from overchuting by a mechanism wherein a device to clamp a paper by a magnet may constantly press down the material pulling to a magnet on the pulling surface of the magnet.
CONSTITUTION: A movable plate 2 is constantly pressed down with a fixed force P in a magnet 1 direction by the recoil strength of a compression coil spring 11. This allows the resultant force caused by the pulling force F acted on a magnet 1 and a movable plate 2 and said compression force P, namely F+P force, to apply to a paper 5 to ensure to secure the paper 5 by printing with the device. While in feeding the paper the energized magnet 1 is shut-off, the compression force of the coil spring 11 is acting, which allows the force of μt to apply to the paper 5 as a load where the friction coefficient between the paper 5 and the adsorbing surface of the magnet 1 and the movable plate 2 is rated as μ, causing to prevent the paper 5 from overchuting.
