Radio control transmitter |
摘要 |
A radio control transmitter capable of preventing a pupil-side radio control transmitter from outputting a radio wave even when a pupil-side operator erroneously closes a power switch of the pupil-side radio control transmitter. The transmitter includes a radio-frequency circuit for modulating a stick operation signal encoded by an encoder and outputting it in the form of a radio wave and a power control section for discriminating which of an internal power supply and an external power supply feeds a power thereto and holding a result of the discrimination therein. The power control section also functions to control switches for feeding the encoder and radio-frequency circuit with a power depending on the discrimination result. A trainer switch is arranged so as to permit a signal to be selectively applied to the radio-frequency circuit 5 from the encoder or a trainer cable. The power control section is fed with a power through the trainer cable from the external power supply or through a diode from the internal power supply,
