  • Patent number: 6526242
    Abstract: An image forming apparatus with a plurality of units operatively connected together is disclosed. A main power switch is mounted on one side wall of a copier body unit while a paper discharge unit next to the copier body unit is formed with a recess facing the main power switch. The recess defines an opening only great enough for a person to touch the main power switch with a fingertip. Even when the different units are combined without any clearance therebetween, the main power switch can be operated via the above opening. In addition, the main power switch is not easily visible and can therefore be prevented from being inadvertently turned off.

  • Patent number: 6259866
    Abstract: An image forming apparatus includes an operation and display device having an LCD (Liquid Crystal Display) panel or similar touch panel and a key portion including various keys mounted on its body. The body is curved with a suitable curvature in the up-and-down direction and right-and-left direction. The display surface of the touch panel and the key portion are positioned on the concave side of the curved body; the key portion is arranged below the display surface. The distance between the concave surface and the operator is the same at all positions on the concave surface. The operator can therefore smoothly operate both of the touch panel and key portion with by moving the operator's arm, hand and eyes little.
