<P>PROBLEM TO BE SOLVED: To provide a booster capable of continuing output of signals even when there is no power supply. <P>SOLUTION: A booster 3 comprises: a booster input terminal 30, an amplifier element 31; a branch 32 for distributing signals amplified by the amplifier element 31 to a power supply time output system and a regular output system; a power supply time output terminal 34 for outputting the signals distributed to the power supply time output system; a regular output terminal 35 for outputting the signals; and a first switch 36a and a second switch 36b for connecting the booster input terminal 30 to the amplifier element 31 to output the signals inputted to the booster input terminal 30 from the power supply time output terminal 34 through the amplifier element 31 and the branch 32 and connecting the regular output terminal 35 to the branch 32 to output the signals distributed to the regular output system by the branch 32 from the regular output terminal 35 when power is supplied, and connecting the booster input terminal 30 to the regular output terminal 35 to output the signals inputted to the booster input terminal 30 from the regular output terminal 35 when there is no power supply. <P>COPYRIGHT: (C)2013,JPO&INPIT |
