     BACKGROUND OF THE INVENTION 
     1. Field of the invention 
     The present invention relates to an easy-to-use food slicer in which a long belt blade is installed. This belt blade is pulled back and forth by an electric motor and transmission system. Food under this slicer is cut to predetermined thickness when this slicer is pressed by users. 
     2. Description of Related Art 
     This invention can slice both meat and vegetables into fine pieces. Food processors are expensive and not convenient to use to prepare food slice for a family. Conventional food slicers are either too complex because of using electrical motors in them or difficult to use without electrical motor. To make a food slicer easy to use for a regular family is needed. 
     This invention refers to united state patent with U.S. Pat. No. 7,055,516. 
     BRIEF SUMMARY OF THE INVENTION 
     To make food slicers easy for family to use, it is an object of the present invention to provide a food slicer to cut food into pieces having a predetermined thickness, which is easier and more efficient than conventional food slicer. 
     To achieve the object of the present invention, there is provided a food slicer comprising a motor, a driving transmission system, belt blade and a structure where belt blade and driving transmission system and motor are installed. The driving transmission system pulls the belt blade from two terminals alternatively so that the blade moves back and forth repeatedly, which will cut food under the food slicer into predetermined thickness. 
     The belt blade is fabricated with a very thin and strong metal belt which has smooth verges. Food is sliced when slicer is pressed on it.

     DETAILED DESCRIPTION OF THE INVENTION 
     Now the reference will be made to the drawings. 
       FIG. 1  is a perspective view of an easy-to-use food slicer according to the present invention. 
     As shown in  FIG. 1  and  FIG. 2 , the easy-to-use food slicer according to the present invention includes a motor  30  and a structure  10  in which the belt blade  14 , four sets of pulleys  11 ,  11 ′,  23 ,  23 ′ and a driving transmission system  12 ,  12 ′,  13 ,  13 ′,  15 ,  16 ,  16 ′,  17 ,  17 ′,  18 ,  19 ,  19 ′,  20 ,  20 ′ are installed, four sets of pulleys  11 ,  11 ′,  23 ,  23 ′ and a driving transmission system  12 ,  12 ′,  13 ,  13 ′,  15 ,  16 ,  16 ′,  17 ,  17 ′,  18 ,  19 ,  19 ′,  20 ,  20 ′. 
     The belt blade is very thin and narrow and fabricated with strong and durable metal so that it can bent around pulleys  11 ,  11 ′,  23 ,  23 ′ and withstand vertical force applied by users of the easy-to-use food slicer. 
     The driving transmission system transforms rotation movement of motor  30  into back and forth movement of belt blade  14 . As shown in  FIG. 3 , the driving transmission system includes one helical gear  18  connected to motor  30 , two vertical gears  19  and  19 ′ connected to helical gears  18 , two driving pulleys  20  and  20 ′ which are installed on the same shafts with gears  19  and  19 ′, a driving belt  15  which drives pulleys  16  and  16 ′, two driven pulleys  16  and  16 ′ which are driven by driving belt  15 , two crank shafts  12  and  12 ′ which are driven by pulley  16  and  16 ′, two rollers  17  and  17 ′ which are installed on crank shafts  12  and  12 ′ and are used to connect belt blade with driving transmission system. The rotation of motor  30  makes vertical gears  19  and  19 ′ rotate. Rotation of vertical gears  19  and  19 ′ makes two driving pulleys  20  and  20 ′ rotate, which causes movement of driving belt  15 . Driving belt  15  makes two driven pulleys  16  and  16 ′ rotate, which causes crank shafts  12  and  12 ′ rotate in the direction. The rotation of crank shaft  12  and  12 ′ cause rollers  17  and  17 ′ rotate horizontally, which pull the belt blade  14  from both terminals alternatively. 
     As shown in  FIG. 4A  and  FIG. 4B , vertical gears  19  and  19 ′ and helical gear  18  are on the top of the structure  10 . Pulleys  16 ,  16 ′,  20  and  20 ′ are in the middle level. Rollers  17  and  17 ′ and belt blade  14  are in the bottom level. The shape of crank shaft  12  and  12 ′ are shown in  FIG. 5 . Side view of pulley sets  11  and  11 ′ and belt blade  14  are shown in  FIG. 6A  and  FIG. 6B . 
     As shown in  FIG. 7 , in the easy-to-use food slicer according to the present invention, food will be sliced by belt blade  14  when users of food slicer press the slicer through food.
