<P>PROBLEM TO BE SOLVED: To provide an optometer comprising a remote control apparatus capable of reliably performing remote control operation without causing radio interference. <P>SOLUTION: A transmission section 16 of the remote control apparatus 10n outputs a remote control signal that is modulated in a carrier frequency:400-500 kHz, in an output pattern different for each remote control apparatus (e.g., P001, P002) multiple times, thereby reliably performing remote control operation without causing radio interference. Furthermore, a standstill term T2 during which transmission of remote control signal is stopped, is set longer than a transmission term T1 during which remote control signals are transmitted, so that radio interference further hardly occurs. <P>COPYRIGHT: (C)2010,JPO&INPIT |
