Publication number: 20020064393Abstract: To form a printer device having the framework which is connected to a plurality of frames, there are included a main frame, as a lower frame adjacent to a surface of a table, etc. on which the printer device is arranged, and a sub-frame which is separated from the main frame. The sub-frame is connected to the main frame at three points. A plurality of image formation units and a conveyer belt are supported by the sub-frame. Even if the main frame is tilted over one side or the other as a result of an external factor, such as a warped surface of the table, such unstable arrangement of the printer device has no effect on the sub-frame. Hence, the engine parts of the image formation units supported by the sub-frame can desirably function. In this structure of the printer device, positional deviation does not occur in image components to be printed, and high quality printing can be performed.Type: ApplicationFiled: January 24, 2001Publication date: May 30, 2002Inventor: Hiroyuki Akimoto
