PURPOSE:To reduce power consumption and to perform transmission even from plural transmitters to a reception side without generating collision simultaneously by deciding a time to the transmission corresponding to an address inherent in the transmitter set by an address input circuit. CONSTITUTION:A clock always oscillated by a second oscillation circuit 15 is frequency-divided to a clock of 100-500ms at a fixed frequency division circuit 14, and a control circuit is operated intermittently by starting up a first oscillation circuit 16. An output interval in the transmission is decided by counting the number (n) of times of the operation of the control circuit by output from the fixed frequency division circuit 14, if the number of times is set constant, the collision is always generated for a long time when plural remote control transmitters start the transmission simultaneously. Therefore, it is possible to generate each different time by changing the number (n) of times of the operation of the control circuit 11 corresponding to an address value set from the outside. In such a way, it is possible to reduce the power consumption and to evade the collision of the transmission. |
