         2 . The paper feed device according to  claim 1 ,
 wherein the stack of paper transfer unit includes a plurality of transfer links that is provided corresponding to the plurality of placing stages and transfers the placing stages, and a plurality of manual operation levers that is connected to the transfer links, respectively.   
     
     
         3 . A paper feed device for peeling and feeding the uppermost paper of stacks of paper, whose one end is attached to the next so as to be peeled, one by one, the device comprising:
 a stack of paper case in which the stacks of paper are received to be parallel to each other in a width direction, the stacks of paper having substantially the same length and the same width or different width;   a plurality of placing stages on which the stacks of paper are placed, respectively, the placing stages being received in the stack of paper case;   a stack of paper transfer unit that separately transfers the stacks of paper at a position between a peeling position and a stand-by position by using the plurality of placing stages; and   a paper feed unit that peels and feeds the uppermost paper of the stacks of paper transferred to the peeling position.   
     
     
         4 . The paper feed device according to  claim 3 ,
 wherein the stack of paper transfer unit transfers one or more selected from the stacks of paper by using the plurality of placing stages.   
     
     
         5 . The paper feed device according to  claim 3 ,
 wherein the stack of paper transfer unit includes a plurality of solenoids that are provided corresponding to the plurality of placing stages and transfer the placing stages.   
     
     
         6 . The paper feed device according to  claim 3 ,
 wherein the stack of paper transfer unit includes a plurality of plate cams that are provided corresponding to the plurality of placing stages and transfer the placing stages, a rotary body that is provided with the plurality of plate cams on the periphery thereof, and an actuator that rotates the rotary body.   
     
     
         7 . The paper feed device according to  claim 3 , further comprising:
 a selection data obtaining unit that obtains selection data used to transfer the desired selected placing stage,   wherein the stack of paper transfer unit transfers the placing stage on the basis of the selection data obtained by the selection data obtaining unit.   
     
     
         8 . The paper feed device according to  claim 1 , further comprising:
 a detecting unit that detects the stacks of paper transferred to the peeling position.   
     
     
         9 . The paper feed device according to  claim 8 , further comprising:
 a case in which the stack of paper case, the plurality of placing stages, the stack of paper transfer unit, and the paper feed unit are housed; and   an indicating unit that indicates in a certain manner on the stacks of paper transferred to the peeling position at positions corresponding to the placing stages of the case on the basis of the results detected by the detecting unit.   
     
     
         10 . The paper feed device according to  claim 1 ,
 wherein a stack of paper having a minimum width, and a stack of paper having a width corresponding to an integral multiple of the minimum width are used as the stacks of paper, and   each of the placing stages has a width corresponding to the stack of paper having a minimum width.   
     
     
         11 . A stack of paper printer, comprising:
 the paper feed device according to any one of  claims 1  to  10 ; and   a printing unit that performs printing on paper fed by the paper feed unit.   
     
     
         12 . A stack of paper printing system, comprising:
 the stack of paper printer according to  claim 11 ; and   a computer that is connected to the stack of paper printer and controls the stack of paper printer.
