A pager which includes, in addition to a message receiving function, a data generation program responsive to an operation for generating and storing data in the memory; and optical communication circuit for generating and transmitting a first optical signal indicative of the message or the generated data in accordance with a data selection command to another pager and for directly receiving a second optical signal including second data from the other pager and outputting the received data; and a receiving control program for storing the received data in the memory in response to a receiving command. It may further comprise: an ID code generation program for generating a first ID code according to the data selection command; a data attaching program for attaching the ID code to the data to be transmitted to another pager. The received data is stored according to the received ID code. A light intensity changing circuit may change an intensity of the first optical signal. Moreover, it is judged whether it is possible to communicate with another pager from the received data; and the user is informed of the judging result.

Wireless terminal device

The present invention has an object to provide a method for generating vibration and a vibration generating apparatus for allowing a single unit to provide a call signal by way of sound and body-sensible vibration. According to the method for generating vibration of the invention, first and second vibration systems having different resonance frequencies from each other are magnetically coupled to each other and a state of energy externally supplied to the systems is selected thereby causing the first vibration system to vibrate relative to the second vibration system for generating a body-sensible vibration, for example. By changing the state of the energy, the second vibration system is caused to vibrate relative to the first vibration system for generating sound.

Vibration generating apparatus

In a cordless telephone system having a mobile telephone set and a charging stand, the mobile telephone set includes at least one charging terminal and a charging control terminal, and control circuitry for monitoring the at least one charging terminal and the charging control terminal, and controlling whether or not the mobile telephone set is permitted to operate in a quick communication mode. The quick communication mode is a communication mode of the mobile telephone set in which the mobile telephone set automatically begins to transmit an outgoing call of the telephone system or to receive an incoming call, when the mobile telephone set is picked up from the charging stand.
