摘要： PROBLEM TO BE SOLVED: To provide an operation control device and an electronic key system which maintains a high security level without losing the convenience. SOLUTION: When a driver performs a registration work to relate a cellular phone 3 to the operation control device 4 (an automobile) prior to the user's (the driver's) use of the cellular phone 3 as the electronic key, an IC card for registration is used. Prior to the registration work using the IC card for registration, the IC card is not prepared by the driver, but a dealer. Therefore, the driver does not need to do any complicated preparation work himself/herself, but only needs to perform a simple registration work using the preferable IC card for registration having the high security level. Consequently, the high security level is maintained without losing the convenience. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an electric key system and a communication unit which can determine permission/non-permission for various vehicle's operations such as door lock and unlock or starting of an engine by other communication terminal irrespective of possession or non-possession of the dedicated key, and wherein a state separately preparing the communication terminal for the purpose hardly occurs even if such structure is adopted, and can ensure security for theft of a vehicle even though various vehicle's operations are admitted by the communication terminal. SOLUTION: A non-contact IC card communication system 16 using a non-contact IC card communication technique called Felica (R) is mounted on the vehicle 1. If a compound ID key having a portable key ID code and its expiration date is transmitted from a cellular phone 18 incorporating a communication circuit 19 corresponding to the Felica (R), an ID checking between a reader/writer 17 and the cellular phone 18 is effected, and the portable key ID code of the communication circuit 19 is within the expiration date, an immobilization lock state by the immobilizer function is released, and an engine can be started.

SOLUTION: An immobilizer function is mounted on the vehicle 1 as a purpose for antitheft of the vehicle. A non-contact IC card communication system 16 using a non-contact IC card communication technique called Felica (R) is mounted on the vehicle. When an ID checking between a reader/writer 17 and a cellular phone 18 is effected by holding the cellular phone 18 incorporating a communication circuit 19 corresponding to the Felica (R) up over in-vehicle antenna 22, an immobilization lock state by the immobilizer function is released, and the starting of an engine is permitted. Therefore, the engine can be started by even a mechanical key 37 having no transponder 2a to be incorporated. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a capacitance sensor circuit less affected by the frequency of a transmitter. SOLUTION: A detection voltage Vo is obtained by amplifying a difference between a voltage Va between a resistor Ro and a capacitor Co and a voltage Vb between the capacitor Co and a detection electrode 2 in a differential amplifier circuit 3. At the time, the difference (the voltage Va - the voltage Vb) between the voltage Va and the voltage Vb is obtained by the voltage Va × the capacitance of a detection capacitor C / (capacitance of the capacitor Co + capacitance of the detection capacitor C), and the influence of the frequency of the transmitter Vc is suppressed. As a result, the result of detecting whether or not a human body touches the detection electrode 2 is output to the detection voltage Vo and the capacitance sensor circuit 1 less affected by the frequency of the transmitter Vc is provided.
