PORTABLE RADIO COMMUNICATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To improve the operability of an operation key and to miniaturize and lighten a portable radio communication equipment. SOLUTION: A floating block 11 is stored in a storage space in a state where first and second casings 1 and 5 are closed. When the first and second casings 1 and 5 are opened with hinge parts 9a and 9b as fulcrums, pins 15 and 16 slide along groove parts 13 and 14 and the movement of the floating block 11 is guided. Thus, the floating block 11 becomes a floating state against the opening/closing of the first and second casings 1 and 5.
