Portable electronic apparatus having an electro-magnetic shield supporting a keyboard
First Claim
1. A portable electronic apparatus comprising:
- a housing having a bottom wall carrying a circuit board thereon;
a substantially rectangular keyboard unit mounted on the housing and facing the circuit board, a peripheral edge portion of the keyboard unit being supported on the housing;
a shielding plate arranged adjacent to the keyboard unit between the circuit board and the keyboard unit, for magnetically shielding the circuit board; and
means for preventing the keyboard unit from bending toward the circuit board, the preventing means including a supporting member extending from the shielding plate and having an extended end abutting against the circuit board.

Abstract
A portable computer includes a housing and a display unit. The display unit is attached to the housing to be movable between a closed position and an opened position. The portable unit may also include a keyboard which can be covered by the display when the display is in the closed position. A circuit board is proximate to the bottom wall of the housing. A shield plate for magnetically shielding the circuit board is disposed inside the housing proximate to the circuit board and can be between the circuit board and the keyboard if a keyboard is provided. At least one supporting member extends from the bottom face of the shielding plate and abuts the circuit board to prevent the keyboard unit, if one is provided, from bending toward the circuit board. The shield plate may include an edge which is supported on the housing. The portable computer may also include bosses positioned between the bottom wall of the housing and the circuit board.
