Biological information measurement device, illumination method in a biological information measurement device, and biological information measurement method

An illumination method in a biological information measurement device that measures biological information of a user and that has a device main body and a fitting-removal section to/from which a sensor that measures biological information of a user is fitted/removed from outside, the illumination method being a method for illuminating the vicinity of the fitting-removal section and comprising:

• a first step of causing light emission by a light source section that is provided within the device main body at a position spaced apart from the fitting-removal section and that functions as a light source for components of the biological information measurement device other than the fitting-removal section;
• and
• a second step of guiding light emitted by the light source section in the first step, to a predetermined position in the vicinity of the fitting-removal section to/from which the sensor is fitted/removed, by way of a light guide member that is provided between the light source section and the predetermined position.

A method for measuring biological information of a user in a biological information measurement device that has a device main body and a fitting-removal section to/from which a sensor that measures biological information of a user is fitted/removed from outside, the method comprising:

• a light emission step of causing light emission by a light source section that is provided within the device main body at a position spaced apart from the fitting-removal section and that functions as a light source for components of the biological information measurement device other than the fitting-removal section;
• and
• a fitting step of fitting the sensor to the fitting-removal section in a state where the light source section in the light emission step is emitting light to a light guide member that is provided between the light source section and a predetermined position in the vicinity of the fitting-removal section.

A method for measuring biological information of a user in a biological information measurement device that has a device main body and a fitting-removal section to/from which a sensor that measures biological information of a user is fitted/removed from outside, the method comprising:

• a fitting step of fitting the sensor to the fitting-removal section;
• and
• a light emission step of, upon fitting of the sensor in the fitting step, causing a light source section that is provided within the device main body at a position spaced apart from the fitting-removal section and that functions as a light source for components of the biological information measurement device other than the fitting-removal section, to emit light to a light guide member that is provided between the light source section and a predetermined position in the vicinity of the fitting-removal section.
