  • Patent number: 6486419
    Abstract: An image forming apparatus having at least two of a plurality of functions including copying, facsimile and printer functions includes a main power switch that is provided on an outer surface of the apparatus and a cover to cover the main power switch. The cover is capable of opening and closing. Because the main power switch cannot be operated unless the cover is opened, when a user inadvertently tries to turn off the main power switch, for example, at the end of a day, the user must first touch the cover and is thereby reminded that the switch which the user is trying to turn off, is actually the main power switch for the apparatus. Thus, the main power switch is prevented from being inadvertently or unconsciously turned off.

  • Patent number: 5913095
    Abstract: An image forming apparatus including a paper cassette loaded with a stack of papers and a paper stacking device for stacking papers carrying images thereon is disclosed. The apparatus has an upper casing part rotatable away from a lower casing part. When the upper casing part is rotated away from the lower casing part, the apparatus successfully prevents the upper casing part from interfering with a tray or similar paper stacking means and prevents papers stacked on the tray from dropping without having its overall length increased. The tray is arranged in the rear portion of the apparatus opposite to the front portion where a control panel is located, thereby reducing the widthwise dimension of the apparatus. Even in such a position, the tray allows papers stacked thereon to be easily picked up.
