<p>PURPOSE:To reduce power consumption of a transmitter for remote control. CONSTITUTION:In this transmitter in which a plurality of operation buttons 2a, 2b,..., a solar battery 3 and a control part 12 sending specific waveform signals by pressing the operation buttons 2a, 2b,..., are provided in a portable case 1 consisting of nonconductor such as synthetic resin, a secondary battery 10 charged by the solar battery 3 is provided in the portable case 1. The input side of the operation buttons 2a, 2b,... are connected to the secondary battery 10 side, the output side of the operation buttons 2a, 2b,... are respectively connected to power lines 14a, 14b,... reaching the main circuit terminal 13 of the control part 12, and signal lines 16a, 16b,... reaching the input circuit 15 of the control part 12. Between the power lines 14a, 14b,... and the signal lines 16a, 16b, diodes 17a, 17b,... for preventing current flow-in are provided.</p> |
