PURPOSE: To prolong the service life of a battery by generating a pulse of an electric signal and applying it to a CPU with a switch operated when the remote control transmitter is gripped.

CONSTITUTION: When a shuttle ball 2 is turned and an operating lever 3 is tilted, a slide member provided to a rear end of the operating lever 3 pushes up a guide 5 slightly. In this case, when a switch 7 is placed under the guide 5 to use the motion and the operator turns the shuttle ball 2 in any direction to operate the remote control transmitter, the guide 5 is pressed down and the switch 7 is activated. When the switch 7 is operated and switched on, since an output of a comparator 8 acting like a start signal generating circuit, a CPU 9 is started by using its trailing. Thus, when the operator grips the remote control transmitter 1 for its operation and is in contact with the shuttle ball 2, the CPU 9 is started.
