Abstract
A sensing device includes a housing, a supporting component, a grating module, a first roller, a second roller, and a control unit. When a media contacts with the second roller, the second roller drives the first roller to move the supporting component relative to the housing according to a thickness of the media, so as to adjust positions of the first roller and a grating wheel of the grating module relative to the housing. When the media drives the second roller to rotate, the second roller drives the first roller to rotate the grating wheel. The control unit determines whether the media proceeds at a predetermined speed according to a corresponding sensing signal generated by the grating module during rotation of the grating wheel, which allows a user to recognize a progress state of the media.
