<p><P>PROBLEM TO BE SOLVED: To satisfactorily prevent scattering of toner from a discharge port 153a of a discharge pipe 153 or operation failure by a simple and inexpensive structure. <P>SOLUTION: The device includes a protection wall 151a which receives at least an open window 152a of a lid pipe 152 when the discharge port 153a of the discharge pipe 153 is laid into a closed state by rotating the open window 152a of the lid pipe 152. The open window 152a of the lid pipe 152 is covered with the protection wall 151a when the discharge port 153a of the discharge pipe 153 is laid into the closed state to prevent an operator from touching the open window 152a of the lid pipe 152. Accordingly, even if toner adheres to the open window 152a of the lid pipe 152 for opening and closing the discharge port 153a of the discharge pipe 153, scattering of the toner can be prevented. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
