A mobile radio terminal comprises a key which has a fingerprint detecting function and operates to input an instruction in correspondence with a pushing position, a memory for registering a fingerprint detected by the key, a fingerprint collating portion for collating the fingerprint registered in the memory with a fingerprint which is newly detected by the key, and a CPU and branch portion for switching to allow the input of the instruction from the key only when it is judged through the fingerprint collation that the fingerprint newly detected is coincident with any one of the fingerprints registered in the memory. |
