Abstract: An attaching/detaching structure for a keyboard module in an information processing equipment for easily mounting, removing and exchanging a keyboard module in a main body of the information processing equipment. For mounting the keyboard module on the body, latch members are pushed into the module. Then, the module is brought close to a concave mounting portion of the main body, with positioning projections in alignment with projection-receiving holes, and the projections are inserted into the holes. After the necessary electrical connection is made, the keyboard module is mounted on the concave mounting portion. Then, the latch members are slid along guide members, using a tool having a portion insertable into a gap between key caps, so that distal ends of the individual latch members are inserted into a corresponding cutout. For detaching the keyboard module, the above procedure is reversed.
