<p>PURPOSE:To constitute the device so that a lap top computer can be used by only a person having a specific ID card by providing an ID card for generating an identification signal in response to a request signal, a signal analysis processing part for analyzing whether the identification signal is correct or not, and a locking release device for releasing a lock at the time when the signal is correct. CONSTITUTION:An ID card 4 which is inserted into a main body 1 and generates an identification signal in response to a request signal is allowed to approach a transmitting part 7 and a receiving part 6, and the signal of the transmitting part 7 is received by the ID card 4 and returned as an answer signal to the receiving part 6. The receiving part 6 transmits the contents of the signal to a signal analysis processing part 5, analyzes whether the identification signal of the ID card 4 is equal to that which is registered in advance or not, and commands a lock release to a locking release device 9 only in the case a result of analysis is the specific contents. In such a way, the security of a lap top computer becomes complete.</p> |
