Patent ID: 8029129

Claim:
A cover support mechanism which regulates an opening angle of an openable cover with respect to a chassis of an electronic device, the cover constituting a portion of the chassis, the mechanism comprising: a cord shaped or tape shaped stopper having a first end portion and a second end portion, the first end portion being fixed to the cover; and a support unit for supporting the second end portion of the stopper, the support unit being provided to the electronic device, wherein the support unit comprises: a receiving portion which has a space for pulling in the second end portion of the stopper; a biasing member adapted to apply force to the stopper for pulling in the stopper into the receiving portion; and a braking unit adapted to apply frictional force to the stopper, the braking unit having a frame defining a hole portion and a notch portion extending from the hole portion, the notch portion having a length longer than a diameter of the stopper, and a width of the notch portion gradually reduces as the notch portion extends away from the hole portion, wherein the stopper extends through the hole portion when the cover is in a closed position, and moves through the notch portion in the direction away from the hole portion as the cover is moved in an open direction, such that the frictional force applied to the stopper gradually increases as the cover is moved in the open direction.
