Classification: CPC G  H | IPC G

Claim 4:
5. An information transmission system using a bell, comprising a first bell device and a second bell device mutually connected to a communication network,
the first bell device being located at a first location, the first bell device having a first bell, a first transmitter-receiver connected to the communication network, a first actuator that is manually operable by a first operator and which actuates the first bell, and a first sensor that detects sound or vibration of the first bell in response to actuation of the first bell, the first bell, wherein the first transmitter-receiver, the first actuator and the first sensor are located at the first location, and
the second bell device being located at a second location remote from the first location, the second bell device having a second bell, a second transmitter-receiver connected to the communication network, a second actuator wherein the second actuator is electronically operable to actuate the second bell, and a second sensor that detects sound or vibration of the second bell in response to actuation of the second bell, wherein the second bell, the second transmitter-receiver, the second actuator and the second sensor are located at the second location,
wherein the information transmission system further comprises:
a controller that analyzes characteristics of ways of ringing of the first bell by an operator based on an output from the first sensor and outputs analyzed information associated with the operator;
a memory that stores operation information including the analyzed information associated with the operator along with ID information of the operator corresponding to the analyzed information of the operator,
wherein in response to an operator manually operating the first bell, the controller determines whether the analyzed information associated with the operator corresponds to the analyzed information stored in the memory and sends an activation signal to the second transmitter-receiver to actuate the second bell when the analyzed information corresponds to that of the certain operator,
wherein in response to the activation signal, the second actuator electronically actuates the second bell at the second location.
