Claims

[Scope of utility model registration request]

A receiving section such as an antenna that receives a signal including a code number transmitted from the base unit, a high frequency amplification and detection section that separates the signal from other noise signals, and a timer circuit that operates using the signal as a trigger; a code identification unit that identifies and compares the code numbers included in the signals separated by the high frequency amplification and detection unit; and a sounding body that produces a sound when the code numbers match; A call card with a code number, characterized by having a built-in call function that turns off a timer circuit with a signal from a code identification section.
