Abstract: A box includes a receiving seat adapted for supporting a keyboard, a mounting seat pivotally connected with the receiving seat, a support rack pivotally mounted on the mounting seat and adapted for supporting a tablet PC, and a support leg mounted between the mounting seat and the support rack to lift the support rack. Thus, when the box is opened, the keyboard is received in the receiving seat, and the tablet PC is supported by the support rack in an inclined manner so that when the box is placed on a table, the tablet PC co-operates with the keyboard to function as a table PC, thereby facilitating a user operating the tablet PC on the table.
