  • Electronic apparatus having switch operated by rotatable display-unit
    Patent number: 6191938
    Abstract: An electronic apparatus is provided with a base unit and a display unit. The base unit has an opening formed on the upper surface. The display unit incorporates a display device and supported by the base unit. The display unit is rotatable between a first position where it is tilted down in such a manner as to cover the upper surface of the base unit and a second position where it is raised in such a manner as to expose the upper surface. The display unit includes a projection portion which is inserted into the opening when the display unit is rotated to the first position. A switch for turning the display device on or off is arranged inside the base unit. The switch includes an operation element opposed to the opening of the base unit. When the display unit is rotated to the first position, the operation element is pushed by the projection portion, thereby turning off the display device.

  • Electronic system having portable electronic apparatus and external expansion unit for expanding function of electronic apparatus
    Patent number: 5592362
    Abstract: An electronic system includes an electronic apparatus body and an external expansion unit. The electronic apparatus body has a bottom surface and a rear surface. A first connector is arranged on the rear surface. The external expansion unit has a first surface opposing the bottom surface, and a second surface opposing the rear surface. The external expansion unit has a second connector which is detachably connected to the first connector. The external expansion unit has an engaging device. The engaging device is movable between the first position where the engaging device is separated from the bottom surface and the second position where the engaging device is engaged with the bottom surface to pull the electronic apparatus body toward the second surface. The external expansion unit has an operation mechanism for selectively moving the engaging device to the first and second positions.
