IPC: G03G21/00
Filed: 2008-06-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that has raised information security for printed matter in an installation environment where many and unspecified users exist.  <P>SOLUTION: A shielding cover 14 performs opening/closing operation according to an instruction from a control section. A sheet member stacking hold member 23 normally receives a sheet member P, and moves downward to connect the paths of an ejection sheet member stacking section 9 and sheet member disposal section 10 in receiving an instruction to discard the sheet member. In this condition, control is exerted so that the shielding cover 14 is securely closed to block access from the outside of the apparatus. If a detecting section 22 detects the presence of the sheet member P after the completion of printing on the sheet member P, the allowance of the opening operation of the shielding cover 14, and the actual opening operation, the control section of the image forming apparatus determines that the sheet member P has been forgotten to be taken, and then discards the sheet member P. Since the ejected-sheet member stacking section 9 is substantially sealed by the shielding cover 14, the apparatus excels in information security.  <P>COPYRIGHT: (C)2010,JPO&INPIT
