         [0045]    The paper sheet W whose other surface is subjected to the coating processing on the impression cylinder  127  is then passed to the conveyance cylinder  131  and the leading edge side thereof is gripped by the gripper of the conveyance cylinder  131 . The paper sheet W is passed from the conveyance cylinder  131  to the conveyance cylinder  133  of the second drying unit  132  and the leading edge side thereof is gripped by the gripper of the conveyance cylinder  133 . The paper sheet W is thereby held and conveyed by the conveyance cylinder  133  with the other surface facing outward. 
         [0046]    In this conveyance, the other surface of the paper sheet W whose other surface is subjected to the coating processing and whose one surface is not subjected to the coating processing is heated and dried by the drying lamps  134 . 
         [0047]    Next, the paper sheet W is passed to the impression cylinder  136  of the one-surface coating unit  135  and the leading edge side thereof is gripped by the gripper of the impression cylinder  136 . The paper sheet W is thereby held and conveyed by the impression cylinder  136  with the one surface (front surface) now facing outward. 
         [0048]    The coating liquid such as varnish applied in advance from the anilox roller  138  and the chamber coater  139  onto a surface of the coating cylinder  137  is applied onto the one surface of the paper sheet W held and conveyed on a peripheral surface of the impression cylinder  136  by causing the paper sheet W to pass between the impression cylinder  136  and the coating cylinder  137 , and the coating processing is thus performed. 
         [0049]    The paper sheet W whose one surface is subjected to the coating processing on the impression cylinder  136  is then passed to the conveyance chain  142  in the paper delivery device  140  via the delivery cylinder  141   a  to be gripped by the not-illustrated gripper bars of the conveyance chain  142 . The paper sheet W is thereby conveyed along the upper travelling chain portion of the conveyance chain  142  with the other surface now facing outward. 
         [0050]    Before the paper sheet W is stacked on the stacking trays  143   a  to  143   c,  the one surface of the paper sheet W conveyed by the conveyance chain  142  is heated and dried by the drying lamps  145  with the paper sheet W being guided and spread while being sucked by the suction guide  144 . 
         [0051]    Then, the paper sheet W is conveyed with the travelling of the conveyance chain  142  and selectively delivered to one of the three stacking trays  143   a  to  143   c.  Specifically, when the printing state is determined to be normal as a result of the checking by the checking device  124 , the paper sheet W is delivered to and stacked on the stacking tray  143   a  or the stacking tray  143   b  as a good item. Meanwhile, when the printing state is determined to be abnormal, the paper sheet W is delivered to and stacked on the stacking tray  143   c  as a defective item. At this time, the paper sheets W delivered onto the stacking trays  143   a  to  143   c  are stacked on the stacking trays  143   a  to  143   c  with the one surfaces (front surfaces) subjected to the aforementioned relief printing and first and second number printing facing upward. 
         [0052]    As described above, in the combination printing press  100  of the embodiment, the relief printing by the relief printing unit  106 , the two types of number printing by the first number printing unit  111  and the second number printing unit  116 , and the double-sided coating by the other-surface coating unit  126  and the one-surface coating unit  135  can be performed in one pass. 
         [0053]    Accordingly, in the combination printing press  100  of the embodiment, there is no need to perform registration again for the double-sided coating after the relief printing and the first and second number printing are performed, and various types of printing and coating can be completed by performing paper conveyance once. Hence, it is possible to improve the quality and productivity of the printing and coating and also reduce a burden on an operator. 
         [0054]    Moreover, since there is no need to perform paper feeding work for the double-sided coating and paper delivery work after the relief printing and the first and second number printing, it is possible to greatly reduce the printing preparation time and also reduce the burden on the operator. 
         [0055]    Furthermore, since intermediate stocks between the step of double-sided coating and the step of relief printing and first and second printing are eliminated, the intermediate stocks can be reduced. In addition, since intermediate defects between the aforementioned steps are eliminated by integrated production, the level of defectiveness can be reduced. 
         [0056]    Moreover, a set of the plate cylinder  108  and the inking device  109  in the relief printing unit  106 , a set of the number cylinder  113  and the inking device  114  in the first number printing unit  111 , and a set of the number cylinder  118  and the inking device  119  in the second number printing unit  116  are disposed respectively below the impression cylinders  107 ,  112 ,  117 , i.e. below a conveyance path of the paper sheet W. Accordingly, the operator can easily perform maintenance and management of parts of the printer while standing on a floor. Specifically, in the relief printing unit  106 , the operator can easily perform replacement work and cleaning work of the plate as well as maintenance, management, adjustment, and the like of the inking device  109 . Moreover, in the first and second number printing units  111 ,  116 , the operator can easily perform attachment and detachment work and position adjustment of multiple numbering machines provided in the number cylinders  113 ,  118  as well as maintenance, management, adjustment, and the like of the inking devices  114 ,  119 . Hence, the burden on the operator can be further reduced. 
         [0057]    Furthermore, since the number printing units  111 ,  116  and the coating units  126 ,  135  are connected to each other only by the transfer cylinders  120 ,  122 , it is possible to perform the passing and receiving of the paper sheet W with high accuracy and further improve the quality of printing and coating with high registration accuracy. 
         [0058]    Moreover, the relief printing unit  106  and the first number printing unit  111  are connected to each other only by the conveyance cylinder  110 , the first number printing unit  111  and the second number printing unit  116  are connected to each other only by the conveyance cylinder  115 , and the other-surface coating unit  126  and the one-surface coating unit  135  are connected to each other only by the conveyance cylinders  131 ,  133 , i.e. all of the units  106 ,  111 ,  116 ,  126 ,  135  are connected to one another only by the conveyance cylinders  110 ,  115 ,  120 ,  122 ,  131 ,  133 . Accordingly, it is possible to perform passing and receiving of the paper sheet W among all of the units  106 ,  111 ,  116 ,  126 ,  135  with high accuracy and more surely improve the quality of all printing and coating with high registration accuracy. 
         [0059]    Moreover, since the relief printing, the two types of number printing, and the double-sided coating are performed not in a satellite-type configuration but in a unit pattern design, it is possible to easily increase and decrease the number of units and replace an old unit with a new unit, thereby improving versatility. 
       Second Embodiment 
       [0060]    A second embodiment of the combination printing press of the present invention is described based on  FIG. 2 . The same parts as those in the aforementioned embodiment are denoted by the same reference numeral as those used in the description of the aforementioned embodiment and description overlapping that of the aforementioned embodiment is omitted. 
         [0061]    In the combination printing press of the embodiment, the impression cylinder  127  of the other-surface (back-surface) coating unit  126  and the impression cylinder  136  of the one-surface (front-surface) coating unit  135  in the combination printing press of the aforementioned first embodiment are in direct contact with each other, and the conveyance cylinder  131  and the second drying unit  132  formed of the conveyance cylinder  133  and the drying lamps  134  are omitted. Meanwhile, one drying lamp (second drying part)  134 A configured to heat and dry the other surface (back surface) of the paper sheet W subjected to the coating processing by the other-surface (back-surface) coating unit  126  is disposed to face an upper peripheral surface (a portion downstream of the contact position between the impression cylinder  127  and the coating cylinder  128  and upstream of the contact position between the impression cylinder  127  and the impression cylinder  136  of the one-surface (front surface) coating unit  135  in the paper conveyance direction) of the impression cylinder  127  in the other-surface (back-surface) coating unit  126 . 
         [0062]    In the combination printing press of the embodiment, the paper sheet W is directly passed from the impression cylinder  127  of the other-surface (back-surface) coating unit  126  to the impression cylinder  136  of the one-surface (front-surface) coating unit  135 , and the relief printing by the relief printing unit  106 , the two types of number printing by the first number printing unit  111  and the second number printing unit  116 , and the double-sided coating by the other-surface coating unit  126  and the one-surface coating unit  135  can be performed in one pass. Accordingly, the combination printing press of the embodiment has, in addition to the same operations and effects as those in the aforementioned embodiment, such an advantage that the length of the printer can be reduced by the reduction of the number of cylinders which is achieved by the elimination of the second drying unit  132 . 
       Third Embodiment 
       [0063]    A third embodiment of the combination printing press of the present invention is described based on  FIG. 3 . The same parts as those in the aforementioned embodiments are denoted by the same reference numeral as those used in the description of the aforementioned embodiments and description overlapping that of the aforementioned embodiments is omitted. 
         [0064]    In the combination printing press of the embodiment, a blanket impression cylinder  150  having a gripper is used instead of the impression cylinder  136  (see  FIG. 2 ) on the one-surface (front-surface) coating unit  135  side, between the other-surface (back-surface) coating unit  126  and the one-surface (front-surface) coating unit  135  in the combination printing press of the aforementioned second embodiment, a blanket cylinder  151  is provided instead of the impression cylinder  127  (see  FIG. 2 ) of the other-surface (back-surface) coating unit  126  to come into contact with an upper peripheral surface of the blanket impression cylinder  150 , and the transfer cylinder  122  of the first drying unit  121  is in direct contact with a peripheral surface of the blanket impression cylinder  150  at a position upstream of the contact position with the blanket cylinder  151  in the paper conveyance direction. Moreover, a rotating direction of the conveyance chain  142  on the delivery cylinder  141  is opposite to that in the combination printing press of the aforementioned second embodiment. Other configurations are the same as those in the aforementioned second embodiment. 
         [0065]    Accordingly, the coating liquid such as varnish applied from the anilox roller  129  and the chamber coater  130  onto the coating cylinder  128  is transferred to the blanket cylinder  151 , and the paper sheet W, which is passed from the transfer cylinder  122  to the blanket impression cylinder  150  and whose leading end is gripped and held by the gripping device of the blanket impression cylinder  150 , is coated with the coating liquid while passing between the blanket cylinder  151  and the blanket impression cylinder  150 . At the same time, the coating liquid such as varnish applied from the anilox roller  138  and the chamber coater  139  onto the coating cylinder  137  is transferred to the blanket impression cylinder  150 , and the one surface (front surface) of the aforementioned paper sheet W is then coated with the coating liquid by a printing pressure of the blanket cylinder  151 . 
         [0066]    In the combination printing press of the embodiment, coating is performed simultaneously on both surfaces of the paper sheet W between the blanket cylinder  151  on the other-surface (back-surface) coating unit  126  side and the blanket impression cylinder  150  on the one-surface (front-surface) coating unit  135  side, and it is possible to perform in one pass the relief printing by the relief printing unit  106 , the two types of number printing by the first number printing unit  111  and the second number printing unit  116 , and the double-sided coating by the other-surface coating unit  126  and the one-surface coating unit  135 . Accordingly, the combination printing press of the embodiment has, in addition to the same operations and effects as those in the combination printing press of the aforementioned second embodiment, such an advantage that the length of the printer can be reduced by the reduction of the number of cylinders which is achieved by the elimination of the impression cylinder  127  ( FIG. 2 ) on the other-surface (back-surface) coating unit  126  side. 
       Other Embodiments 
       [0067]    In the aforementioned embodiments, the relief printing unit  106  is disposed between the sheet feeding part and the first number printing unit  111 . However, as another embodiment, the relief printing unit  106  can be disposed between the second number printing unit  116  and the other-surface coating unit  126  for example. The same operations and effects as those in the aforementioned embodiments can be obtained as long as the relief printing unit  106  is disposed at a position where the relief printing can be performed on the paper sheet W before the coating processing in the coating units  126 ,  135 .
