<P>PROBLEM TO BE SOLVED: To improve safety and operability without giving a complicated impression of appearance or giving a sense of discomfort to a sound person during operation, while preventing the damage of fingers in operation by a vision-impaired person or wrong setting or malfunction. <P>SOLUTION: The height H from the key setting surface 58 to the key top of a mode setting key 52 is set equal to those of other keys set on a panel surface 57 or the like, and a predetermined length H1 that is the difference between the panel surface 57 and the key setting surface 58 is set longer than the height H2. The key top of the mode setting key 52 is not exposed onto the panel surface 57. Even if part of a document protruded from a document table 12 is located above the operation panel 5, the part of the document never makes direct contact with the mode setting key 52. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
