One example of the action of following explanation operational part 31 and judging part 32.
Operational part 31 asks for the absolute value of the difference of the output signal of organism temperature sensor 21 and the output signal of ambient temp sensor 22.Specifically, the output signal of organism temperature sensor 21 is the temperature measured by organism temperature sensor 21, and the output signal of ambient temp sensor 22 is the temperature measured by ambient temp sensor 22.
Judging part 32, when the absolute value of difference is more than 1st threshold value, is judged as that apparatus main body 2 is provided at human body, on the other hand, when the absolute value of difference is less than the 1st threshold value, is judged as that apparatus main body 2 is not provided at human body.1st threshold value be in order to can judgment means main body 2 equip and unequipped to human body predetermined value, can according to the condition of field of employment or sensor accuracy etc. different and suitable change setting.1st threshold value is such as 0.5 DEG C, also can be 1 DEG C or 2 DEG C etc. according to condition difference.
At this, as an example, illustrate the relation of the mensuration temperature of organism temperature sensor 21 and the mensuration temperature of ambient temp sensor 22 at Fig. 4 A and Fig. 4 B.The mensuration temperature of organism temperature sensor 21 indicated by the solid line, represents the mensuration temperature of ambient temp sensor 22 with dotted line.At horizontal axis representing time [s], represent temperature [DEG C] at the longitudinal axis.
In Figure 4 A, the absolute value of the difference of the mensuration temperature of organism temperature sensor 21 and the mensuration temperature of ambient temp sensor 22 is more than the 1st threshold value (being set to 0.5 DEG C in illustrated example, identical below).Therefore, under the state of Fig. 4 A, be judged as that apparatus main body 2 is provided at human body by judging part 32, can using the mensuration temperature of organism temperature sensor 21 at this moment as human body temperature.
In figure 4b, the absolute value of the difference of the mensuration temperature of organism temperature sensor 21 and the mensuration temperature of ambient temp sensor 22 is less than the 1st threshold value (0.5 DEG C).Therefore, under the state of Fig. 4 B, be judged as that apparatus main body 2 is not provided at human body by judging part 32, can not using the mensuration temperature of organism temperature sensor 21 at this moment as human body temperature.
Therefore, by the action of operational part 31 as described above and judging part 32, can the equipment of judgment means main body 2 or unequipped simply.
Judging part 32 also carries out following action.Judging part 32 is being judged as under the state that apparatus main body 2 is not provided at human body, when the absolute value of the variable quantity of the time per unit of the absolute value of difference becomes more than 2nd threshold value, is judged as that apparatus main body 2 starts to be arranged on human body.On the other hand, judging part 32 is being judged as under the state that apparatus main body 2 is equipped in human body, when the absolute value of the variable quantity of the time per unit of the absolute value of difference becomes more than 2nd threshold value, is judged as that apparatus main body 2 starts to unload from human body.2nd threshold value is in order to can the equipment of judgment means main body 2 and the unequipped change of apparatus main body 2 and predetermined value, can according to the condition of field of employment or sensor accuracy etc. different and suitable change setting.2nd threshold value is such as 0.2 DEG C/10s, also can be 0.5 DEG C/10s or 1 DEG C/10s etc. according to condition difference.
At this, as an example, illustrate the relation of the mensuration temperature of organism temperature sensor 21 and the mensuration temperature of ambient temp sensor 22 at Fig. 5 A.The mensuration temperature of organism temperature sensor 21 indicated by the solid line, represents the mensuration temperature of ambient temp sensor 22 with dotted line.At horizontal axis representing time [s], represent temperature [DEG C] at the longitudinal axis.The absolute value (temperature difference) of the difference of the mensuration temperature of organism temperature sensor 21 and the mensuration temperature of ambient temp sensor 22 is shown at Fig. 5 B.At horizontal axis representing time [s], represent temperature difference [DEG C] at the longitudinal axis.
As shown in Figure 5A, the mensuration temperature of organism temperature sensor 21 changes with the process of time.Namely, when the time is 0 ~ t1, temperature keep 34.1 DEG C constant, when the time is t1 ~ t2, temperature 34.1 DEG C ~ 34.6 DEG C ground is interim to be increased, when the time is t2 ~ t3, temperature keep 34.6 DEG C constant, when the time is t3 ~ t4, temperature 34.6 DEG C ~ 34.1 DEG C ground is interim to be reduced, after the time is t4, temperature keep 34.1 DEG C constant.On the other hand, even if the mensuration temperature elapsed time of ambient temp sensor 22 is also constant, keep 34.1 DEG C constant.
As illustrated in fig. 5b, when the time is 0 ~ t1, temperature difference keeps 0 DEG C of difference, and when the time is t1 ~ t2, temperature difference 0 DEG C ~ 0.5 DEG C ground is interim to be increased, when the time is t2 ~ t3, temperature difference keep 0.5 DEG C constant, when the time is t3 ~ t4, temperature difference 0.5 DEG C ~ 0 DEG C ground is interim to be reduced, when the time is after t4, temperature difference keep 0 DEG C constant.
Judging part 32 as described above, when temperature difference is more than 1st threshold value (0.5 DEG C), is judged as that apparatus main body 2 is equipped in human body, when temperature difference is less than the 1st threshold value (0.5 DEG C), is judged as that apparatus main body 2 is unequipped at human body.Thus, when the time is t2 ~ t3, be judged as that apparatus main body 2 is equipped in human body, when the time is after 0 ~ t2 and t3, be judged as that apparatus main body 2 is unequipped at human body.
Then, judging part 32 is being judged as under the state that apparatus main body 2 is provided at human body, become the 2nd threshold value at the absolute value of the variable quantity (slope of temperature difference) of temperature difference time per unit and (be set to 0.2 DEG C/10s in the example shown in the series of figures, identical below) more than time, be judged as that apparatus main body 2 starts to be arranged on human body.Therefore, the time be 0 ~ t2, be judged as the unequipped state at human body of apparatus main body 2 under, when the time is t1 ~ t2, because the absolute value of the slope of temperature difference becomes more than the 2nd threshold value (0.2 DEG C/10s), therefore, when the time is t1 ~ t2, be judged as that apparatus main body 2 starts to be arranged on human body.
Similarly, after the time is t3, be judged as the unequipped state at human body of apparatus main body 2 under, when the time is t3 ~ t4, because the absolute value of the slope of temperature difference becomes more than the 2nd threshold value (0.2 DEG C/10s), therefore, when the time is t3 ~ t4, be judged as that apparatus main body 2 starts to be arranged on human body.
In addition, when the time is t2 ~ t3, although be judged as that apparatus main body 2 is equipped in human body by judging part 32, the absolute value due to the slope of temperature difference is less than the 2nd threshold value (0.2 DEG C/10s), therefore unloads from human body by judging part 32 can not be judged as apparatus main body 2.
Therefore, by the action of judging part 32 as described above, can simply judgment means main body 2 from equipment to unequipped change and apparatus main body 2 from unequipped to the change of equipment.
According to described biological information measurement device 1, the difference of the output signal of operational part 31 computing organism temperature sensor 21 and the output signal of ambient temp sensor 22, judging part 32 carrys out judgment means main body 2 based on the operation result of operational part 31 and whether is equipped in human body.Thus, can distinguish the temperature measured by organism temperature sensor 21 is the temperature of apparatus main body 2 when being provided at human body, or temperature when apparatus main body 2 unloads from human body.Therefore, even if when apparatus main body 2 unloads from human body, organism temperature sensor 21 determines environment temperature, also can not think environment temperature by mistake human body temperature.Such as can prevent error monitoring human body temperature.Can check whether user is equipped with apparatus main body 2 in addition.
At this, in existing biological information measurement device, suppose to want wearing off of judgment means main body, consider to use the optical sensor worn off being used for checkout gear main body.Therefore, because the structure of optical sensor is different with the structure of temperature sensor, therefore optical sensor and temperature sensor have to control in a variety of ways.On the other hand, in the application's utility model, add 1 ambient temp sensor 22, asked for organism temperature sensor 21 and judge to equip wearing off of main body 2 with the difference of ambient temp sensor 22.Therefore, because the structure of ambient temp sensor is identical with the structure of organism temperature sensor, therefore ambient temp sensor and organism temperature sensor can control in the same way.
(the 2nd embodiment)

Battery saving mode control part 35 be judged as by judging part 32 apparatus main body 2 unequipped at human body time, apparatus main body 2 is controlled at battery saving mode.At this, so-called battery saving mode refers to the pattern suppressing power consumption, such as, refer to the lightness of the liquid crystal panel reducing biological information measurement device 1.
Therefore, because apparatus main body 2 controls at battery saving mode when unequipped apparatus main body 2 by battery saving mode control part 35, therefore power consumption can be cut down.In addition, user can be avoided having to oneself be set as the loaded down with trivial details of battery saving mode.So, owing to there is no need for the special operation being set as battery saving mode, be therefore effective to child or People especially.In addition, due to power consumption can be reduced, therefore the battery that electric power is little can be used.
Apparatus main body 2, when being judged as that apparatus main body 2 is equipped in human body by judging part 32, controls in power saving off mode by power saving off mode control part 36.At this, so-called power saving off mode refers to the pattern relieving battery saving mode, such as, refer to and the lightness of the liquid crystal panel of biological information measurement device 1 is reverted to common lightness.
Therefore, because apparatus main body 2 controls in power saving off mode when the equipment of apparatus main body 2 by power saving off mode control part 36, therefore common use can be returned to rapidly.
