Abstract:
1. A sheet laminating apparatus with a jamming detection function, said sheet laminating apparatus being used to laminate a document between an upper thermoplastic film and a lower thermoplastic film and comprising: a laminating channel used as a path of transmitting said document; a laminating roller assembly including an inlet side and an outlet side, wherein said document is fed into said laminating roller assembly through said inlet side and exited from said laminating roller assembly through said outlet side, so that said document is laminated by said laminating roller; a motor connected with said laminating roller assembly for providing motive power to said laminating roller assembly; a distance sensor disposed in the vicinity of said inlet side of said laminating roller assembly for measuring a moving distance S a document sensor disposed in the vicinity of said outlet side of said laminating roller assembly for detecting a transmitting status of said document, wherein said document sensor is separated from said distance sensor by a spacing interval S a controller connected with said distance sensor and said document sensor for discriminating whether a jamming condition of said sheet laminating apparatus occurs, wherein if said moving distance S
