1. A portable biological information monitor apparatus which is adapted to be attached to a body of a test subject when it is used, comprising:
biological information detection means for repeatedly detecting biological information reflecting at least two of (i) pulse, (ii) body motion, and (iii) autonomic nervous function of the test subject;
barometer generation means that has a plurality of generation modes corresponding to the test subject's actions and operates in any of the generation modes, wherein the generation modes include at least a first generation mode to generate a sleep evaluation barometer as a barometer for evaluation of a test subject's status in sleep based on the biological information detected by the biological information detection means and a second generation mode to generate a wake evaluation barometer as a barometer for evaluation of a test subject's status in wake based on the biological information detected by the biological information detection means; and
storage means for storing the barometer generated by the barometer generation means,
wherein the barometer generation means changes timing for generation of the barometer in accordance with the generation mode,
wherein the barometer generation means changes a time interval for generation of the barometer in accordance with the generation mode,
wherein the biological information detection means includes an optical pulse wave sensor to detect a pulse wave by utilizing a light absorbing characteristic of a blood component.
