Abstract
PURPOSE:To perform calling by installing an oscillator in a table in a restaurant, etc., by an electric circuit part including an antenna, a battery, and an oscillating circuit, and housing a channel setter in a container and by providing the electric circuit part with a switch circuit which connects the battery. CONSTITUTION:An electric circuit part 16 consists of an antenna 21, a battery 8, an oscillating circuit 17, a frequency dividing circuit, and a rectangular-wave generating circuit. When a push-button switch 23 pressed, the battery 8 is connected to the circuit part 16, and the frequency division output of the output of the oscillating circuit 17 and the output of the rectangular-wave generating circuit are led to an IC through a switch 11 constituting a channel setting circuit 10. An output appearing at an IC terminal delta is radiated into the air from an antenna 21 through a carrier oscillating circuit 18 and an amplifying circuit 19.
