When the upper part enters, the subject P2 is face-authenticated and the resident ID is specified.

When the subject P2 is face-authenticated by the face authentication part 12a and the resident ID is identified, the body temperature determination part 12b determines the body temperature based on the data signal from the infrared sensor 9 input via the general-purpose input/output port 19. , determines the temperature T of the subject P2. More specifically, based on data signals corresponding to the infrared energy detected in each of the plurality of light receiving ranges C1 to C64 (FIG. 6) of the infrared sensor 9, the temperatures T1 to T64 of each of the plurality of light receiving ranges C1 to C64 are determined. is calculated, and the highest temperature among them is determined as the body temperature T of the subject P2. For example, the temperatures T36 and T37 of the light receiving ranges C36 and C37 (FIG. 6) corresponding to the vicinity of the forehead of the subject P2 are determined as the body temperature T of the subject P2.

The information on the body temperature T of the subject P2 determined by the body temperature determining section 12b is associated with the resident ID of the subject P2 identified by the face authentication section 12a, and sent via the information output section (print antenna) 16. is sent to the management server 30.

That is, when the sight line of the user P1 is aimed at the subject P2 (FIG. 4A), and the subject P2 enters the photographing range AR2 of the camera 8 and the detection range AR3 of the infrared sensor 9 (FIG. 6), the subject P2 P2 is face-authenticated and body temperature T is automatically measured (step S1→S2). As a result, each time the sight line of the user P1 is aimed at the subject P2, identification of the resident ID, temperature measurement, and recording of the temperature measurement result are automatically performed. In addition, the temperature of the subject P2 can be measured with high accuracy.

FIG. 10 is a diagram for explaining an example of body temperature T information managed by the management server 30. As shown in FIG. As shown in FIG. 10, information on body temperature T is accumulated in the management server 30 as time-series information to which information on time t is added for each resident. Each resident's body temperature T is measured by the apparatus 1 each time the resident faces the care staff (user) P1 as the person P2 to be measured, and is transmitted to the management server 30 together with time information and accumulated.
