     Firstly, it is to explain about an operation that drives the document cover unit  50  rotate with respect to the flat bed unit  40  by referring to  FIG. 9  and  FIG. 10 . Here,  FIG. 9A  is a front diagram showing conditions of closing a document cover unit;  FIG. 9B  is a part enlargement sectional diagram of  FIG. 9A ;  FIG. 10A  is a front diagram showing conditions of opening a document cover unit; and  FIG. 10B  is a part enlargement sectional diagram of  FIG. 10A . 
     In a compound apparatus  1 B of the second embodiment, as shown by  FIG. 9A  and  FIG. 9B , the document cover unit  50  is axially supported capable of rotating with respect to the right end side of the flat bed unit  40  through a rotation fulcrum axis  81  that extends to the front and back directions by replacing the rotation fulcrum axis  61  of the first embodiment. In the present embodiment, the rotation fulcrum axis  81  is fixed with respect to the document cover unit  50 , and is supported capable of rotating by being inserted into a rotation fulcrum axis use ditch  84  furnished in the flat bed unit  40 . Then, as shown by  FIGS. 9A and 9B , in conditions of closing the document cover unit  50 , the compound apparatus  1 B can read a manuscript through conveying the manuscript to the manuscript loading surface  41  by using the automatic manuscript conveying apparatus  53 . 
     Then, in conditions of opening the document cover unit  50  as shown by  FIG. 10A , a stopper wall  82  furnished in the document cover unit  50  and a stopper wall  83  furnished in the flat bed unit  40  are contacted as shown by  FIG. 10B , consequently the rotation region of the document cover unit  50  is regulated within 90 degrees (from parallel to verticality with respect to the flat bed unit  40 ). Like this, in conditions of opening the document cover unit  50 , it becomes possible to load a manuscript on the manuscript loading surface  41  in the compound apparatus  1 B. 
     &lt;Rotation Operation of the Scanner Section  3 &gt; 
     Continuously, it is to explain about an operation that drives the scanner section  3  rotate with respect to the printer section  2  by referring to  FIGS. 9A ,  9 B,  10 A &amp; 10 B. Here,  FIG. 9A  is a front diagram showing conditions of closing a scanner section;  FIG. 9C  is a part enlargement sectional diagram of  FIG. 9A ;  FIG. 11A  is a front diagram showing conditions of opening a scanner section; and  FIG. 11B  is a part enlargement sectional diagram of  FIG. 11A . 
     In the compound apparatus  1 B of the second embodiment, as shown by  FIG. 9A  and  FIG. 9B , the scanner section  3  is axially supported capable of rotating with respect to the left end part of the printer section  2  (stay  2   g ) through the rotation fulcrum axis  71  that extends to the front and back directions. 
     Then, in conditions of opening the scanner section  3  as shown by  FIG. 11A , the stopper wall  72  furnished in the flat bed unit  40  and the stopper wall  73  furnished in the stay  2   g  are contacted as shown by  FIG. 11B , the rotation region of the scanner section  3  is regulated within 90 degrees (from parallel to verticality with respect to the printer section  2 ). 
     In the compound apparatus  1 B of the present embodiment, because the rotation fulcrum axis  71  of the scanner section  3  and the rotation fulcrum axis  81  of the document cover unit  50  are respectively furnished opposite to the left and right sides, it becomes possible to open the scanner section with preventing that the document cover unit  50  is unnecessarily opened. Therefore, it is possible to abolish any rotation regulation member for regulating unnecessary rotations of the document cover unit  50 . 
     The above is to explain about the embodiment of the present invention, but the present invention is not limited to the foregoing embodiments but many modifications and variations are possible within the spirit and scope of the appended claims of the invention. For example, in the case to apply the present invention to a monochrome copy machine, it is possible to serve the print process cartridge  23   a  and the transfer roller  23   c  as one. Further, it is also possible to change the shape of the top cover  2   f  and the shape of the rotation fulcrum axes  61 ,  71  and  81  suitably. Furthermore, the compound apparatus of the present invention is not limited to the copy machine, but it is also possible to apply to a facsimile, an office use compound machine (MFP: Multi Function Products) and the like. 
     It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
