     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0025]    Referring to the drawing and in particular to FIG. 1, the invention comprises a payout device for sheets. An elevator  11  is provided in the form of a big rectangular plate (see the lower portion of FIG. 1). Elevator  11  acts to pile the sheet bodies such as bills and to upwardly carry the layered sheet bodies.  
         [0026]    The elevator  11  is equipped to rise when the weight is lightened. This is accomplished by means of a spring (not shown) and the like which is sensitive to the weight. Two standing guide frames  12 ,  13  surround each end part of the elevator  11 . The standing guide frames  12 ,  13  are, for instance, plate bodies which are formed to be bent in the U-shaped form.  
         [0027]    In the upper portion of guide frame  12  on the left or outlet side of the apparatus as shown in FIG. 1, an outlet  14  is formed to pay out a sheet body (not shown). At the lower edge of this outlet  14 , a guide fragment  15  is provided.  
         [0028]    Near the upper outside portion of the outlet  14  a gripper in the form of, two pairs of rubber rollers  16 ,  17  are disposed. These rubber rollers  16 ,  17  act to sandwich and draw out the sheet body. These rollers  16 ,  17  are preferably mounted on a case  34  of a box form which covers the whole apparatus and forms a drawer means.  
         [0029]    A sheet body suction apparatus  21  is provided as a slightly big box form, shown at the center of FIG. 1. This suction apparatus  21 , as shown in FIG. 2 and FIG. 4, is provided with a lower part or receiving side with an opening  22  and the upper part with a small opening  23 .  
         [0030]    The suction apparatus  21  is fixed on by welding or the like inside the guide frame  13 . The guide frame  13  is intervened by one pair of protruded arms  24 ,  25 . The suction apparatus  21  is, as shown in FIG. 2, formed at the slightly raised and diagonal posture against the elevator  11 .  
         [0031]    At the center on the suction apparatus  21 , a small fan apparatus  26  is disposed. In the drawing, the fan apparatus  26  is illustrated schematically. When the fan apparatus  26  is driven, as shown at the arrow in FIG. 2, air flows to the small opening  23  from the big opening  22 . As an alternative an insert tube (not shown ) may be provided, inserted into the small opening  23  instead of the fan apparatus  26 . Such an insert tube may be mounted in an airtight manner for providing suction.  
         [0032]    In the big opening  22  of suction apparatus  21  at nearly the outlet  14 , a small rubber wheel in the form of a small rubber tire  27  is rotatably disposed on an shaft. A pulley  28  is fixed at the out end of the rotating axis of tire  27 . This tire  27  operates to send out a sheet body (not shown ) which was absorbed or sucked up at the opening  22  of suction apparatus  21  to the direction of outlet  14  by the frictional power which occurs based on contact between the sheet body and the rubber wheel  27 . A motor  29  is provided on the suction apparatus  21 . The motor  29  is fixed to a pulley  30  which is provided on the shaft axis of the motor  29 . A rubber belt  31 , which acts as a transmission device, is expanded over the pulleys  28 ,  30  to provide a pulley pair.  
         [0033]    The operation of the embodiment which comprises the above-mentioned constitution, is described below firstly as with reference to the showing of FIG. 5A. A plurality of sheet bodies S are piled on the elevator  11  in a layered manner. When the sheet body S is a bill, a gap G between the first sheet body S 1  on the sheet bodies S and the edge most below in the opening  22  is desirably about 5 mm. However, the size of gap G may be changed on the basis of the size, the thickness, the weight and the like such as sheet bodies S which are in the form of a card. Therefore, one is not limited to above-mentioned numerical value, of course.  
         [0034]    Next, when the suction apparatus  26  is driven, as shown in FIG. 5B, the air is blown upwardly and the negative pressure occurs in the opening  22 . The sheet body S 1 , the uppermost top sheet body S, is as a result absorbed or sucked up at the opening  22 , as shown in FIG. 5B. In this case, the underside of the suction apparatus  21 , i.e. the edge surface on the opening  22  has an angle K (referring to FIG. 5A) to the horizontal plane. Therefore, the sheet body S 1  is, as shown in FIG. 5B, bent at a bend line located at ⅓ from the right or opposite side of the apparatus or the body S 1 .  
         [0035]    As a result, in case of sheet bodies S being new bills, or in case of sheet bodies S being so-called new tickets, by this bend, the top new bill is totally separated from the new bill below. Therefore, there is the certainty that two-sheets (sheet bodies S) do not pass out. In case of cards it may not be possible to provide for such a bend or the like. The angle K is not necessary.  
         [0036]    Moreover, at the underside of the box-shaped suction apparatus  21 , as seen in FIG. 2, the opening edges  32 ,  33  form a part of a receiving surface of the receiving side. As shown in FIG. 4B, the area of the opening  22  is larger than the area of the receiving surface. The receiving surfaces formed by edges  32 ,  33  on either side of the opening  22  are curved slightly and projectingly to the lower direction, as shown FIG. 4A. In the case of a bill in which a short portion is left with the sheet body S rounded or curled, the bill is curved to the direction of the width of the bill with the curve of opening edges  32 ,  33  when the bill is absorbed by the suction apparatus  21 . Therefore, the curl in the length direction is removed and the bill becomes flat. However, the opening edges  32 ,  33  on either side may also be curved and depressed to the upper direction, contrary to FIG. 4A.  
         [0037]    Also, in case of the sheet body S which doesn&#39;t have a curl and the like, the curves of the concave or convex opening edges  32 ,  33  are not necessary of course.  
         [0038]    Next, in the condition shown in FIG. 5B, when the motor  29  is operated, the tire  27  is rotated through the pulley  30 , the belt  31 , the pulley  28 . As the result, as shown in FIG. 5C, the sheet body S 1  which is absorbed on the opening  22  is sent out to the direction of outlet  14  by the friction power of the tire  27 .  
         [0039]    When the about ¼ portion on the left side (viewing FIG. 5C) of sheet body S 1  is sent out, the tip part of this sheet body S 1  is sandwiched between rollers  16  and  17  which are paired. As soon as this is sandwiched, it is quickly dragged by the rollers  16 , 17  which turn faster than the tire  27  and, as shown in FIG. 5D, it begins to be paid out to the outside direction.  
         [0040]    When moving from the condition of FIG. 5C to the condition of FIG. 5D, the tip part of the first sheet body S 1  is put between a pair of rollers  16  and  17 , and an approximately ⅔ portion on the left side of sheet body S 1  is sent out from the suction apparatus  21 . At this time, the illustration is omitted and, the about a right half portion of opening  22  (in FIG. 5D) is released, and the center of the following second sheet body S 2  is sucked and rises up.  
         [0041]    Moreover, when the whole opening  22  is released, the following sheet body S 2  is, as shown in FIG. 5D, absorbed at the opening  22  of the suction apparatus  21 . Further, in the operation description at the above mentioned FIGS.  5 A- 5 D, the suction apparatus  21  is continuously driven and the tire  27  is rotated as needed. However, continuous rotation of the tire  27  is also possible and the calculation of the number of sheet bodies S to pay out is made with another apparatus (not shown).  
         [0042]    The invention allows a payout of sheet bodies S surely and with certainty and moreover at higher speed than prior devices. Also, according to the invention and the disclosed preferred embodiment, the tire (or wheel) is disposed within the opening  22  of the suction apparatus. However, depending on the size, the hardness and the like of sheet body S, the opening  22  is made small and the tire  27  may be disposed outside of opening  22 . In this case, the tire  27  touches a part of the sheet body S which is outside the suction apparatus  21  or a part of the card body and, the sheet or card body is sent out by the frictional power.  
         [0043]    Also, in the description so far, a sending out apparatus of which the elevator  11  is arranged below is illustrated. However, being based on the size, the thickness of the sheet or the card body and the like, the apparatus of which the elevator  11  is arranged diagonally or perpendicularly or above is permitted of course. In other words, depending on the size, the thickness of the sheet or the card body and the like, even if the sending out apparatus illustrated is mounted on a setting up condition or on a upside down condition or on a tumble condition, a similar operation is gotten of course.  
         [0044]    According to this present invention above mentioned, by the combination with simple constitution, a desirable effect is achieved that a sheet body payout apparatus is provided with a small and simple structure. That is, by combining a suction means of the fan and the like and a sending out means of the tire and the like according to this present invention, a sheet body payout apparatus with the small and simple structure is attained.  
         [0045]    In addition, according to this present invention, a big advantage is also attained that sheet bodies one by one can be sent surely and at high speed.  
         [0046]    While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
