Abstract: A tuner mounting mounts a tuner to a musical instrument to indicate a tuning state of the musical instrument. The tuner mounting device has a hook-and-loop fastener that connects to a main body of the tuner and is configured to wrap directly around at least a part of the instrument so that end portions of the hook-and-loop fastener are removably connected to one another to directly mount the tuner main body to the part of the instrument.

Abstract: Provide a tuner mounting device which does not scratch an instrument and which provides a satisfactory sensitivity to a vibration generated from the instrument. A mounting base portion for fixing a tuner main body to a part of the instrument is fixed to the instrument on a constant basis by a hook-and-loop fastener, with a structure to be fitted into the mounting base portion being provided on a lower surface of a tuner main body containing a vibration sensor for detecting vibration generated through operation of the instrument. The mounting base portion has a power source portion and a power supply contact, with the structure having an electrical contact corresponding to the power supply contact provided on the mounting base portion.

Abstract: A living body information detecting terminal (2) is controlled from the side of a living body information monitoring device (3) connected to the living body information detecting terminal (2). In particular, a first living body information detecting sensor that is driven at all times or a second living body information detecting sensor that is in a power-save state or performs measurement in an intermittent manner during normal conditions, is selected, determined, and controlled from among living body information detecting sensors (5) provided to the living body information detecting terminal (2) depending on its wearer, and the second living body information detecting sensor is operated with transmission of an abnormality signal from the first living body information detecting sensor as a trigger.
