Abstract: A mounting device for mounting a peripheral device on a casing of an electronic apparatus includes a pair of spaced-apart upright mounting plates, each having a lower edge adapted to be fixed to a base plate of the casing, and each being formed with a mounting recess on one side confronting the other mounting plate. The mounting recess is defined by a pair of upright clamping walls and a connecting wall which interconnects the clamping walls. Each of a pair of anchoring members has an upright engaging wall formed with an engaging projection adapted to engage a respective outer side wall of the casing, and a pair of wing portions extending transversely, from the engaging wall. The anchoring members are inserted respectively into the mounting recesses via open upper ends of the latter, and are clamped between the clamping walls of the respective mounting recess.
