Abstract
Abstract A vibration detection device includes a detecting device for detecting a vibration, and an output from the amplifying device obtained when outputting a detection signal on the basis of the detection result, an amplifying device for amplifying the detection signal, an initializing device for initializing the output from the amplifying device, and an adjusting device for adjusting the output from the amplifying device so that an output from the amplifying device obtained when the amplifying device is initialized, and an output from the amplifying device obtained when the amplifying device is not initialized and the detecting device generates no signal have substantially the same values.
