When the smartphone 40 acquires a shutter command based on the blinking signal of the light included in the image (YES in S123), the smartphone 40 acquires the image being measured (S124). It is possible to improve the possibility that the person to be measured who blows exhaled air into the alcohol measuring device 20 is included in the image during measurement, and as a result, it is possible to suppress the occurrence of spoofing measurement.

In particular, in the alcohol measuring system 10, when the alcohol measuring device 20 detects that exhaled air is blown during the measurement of the alcohol concentration (YES in S143), the alcohol measuring device 20 outputs a shutter command (S148). It is possible to further improve the possibility that the image of the person to be measured injecting exhaled air into the alcohol measuring device 20 is included in the image during measurement.

It should be noted that the alcohol measuring device 20 determines that the timing of outputting the shutter command when it detects that exhaled air is blown during the measurement of the alcohol concentration is equal to or higher than the specific expiratory pressure in S143 immediately before the mouse. A timing other than the timing determined in S146 that the flow rate of the exhaled air blown into the piece 22 has reached a specific flow rate may be adopted. For example, the alcohol measuring device 20 is at any timing from the start of blowing breath into the alcohol measuring device 20 by the person to be measured to the end of blowing breath into the alcohol measuring device 20 by the person being measured. A shutter command may be output. For example, the alcohol measuring device 20 may output a shutter command when the expiratory pressure detected by the expiratory pressure sensor 26 exceeds 0.

Further, the alcohol measuring device 20 may output a shutter command at a specific timing during the measurement of the alcohol concentration regardless of whether or not it has detected that the exhaled breath has been blown. For example, the alcohol measuring instrument 20 may output a shutter command after the switch 23 is pressed and before detecting that exhaled breath has been blown. The start of measurement of the alcohol concentration by the alcohol measuring device 20 is, for example, the time when the switch 23 is pressed. Further, the end of the measurement of the alcohol concentration by the alcohol measuring device 20 is, for example, the time when the measurement result information is output to the outside of the alcohol measuring device 20. This output includes a display by the display unit 24 and a transmission by the communication unit 30.

In the alcohol measuring system 10, when the alcohol measuring device 20 includes an external light shielding unit as shown in FIGS. 4 and 5, the light from the external light source 91 is measured when the alcohol measuring device 20 performs the measurement of the alcohol concentration. Since the external light shielding portion suppresses the 91a from hitting the light emitting device 25, for example, even when the alcohol concentration is measured by the alcohol measuring device 20 in a place where the influence of sunlight is expected, the light emitting device 25 It is possible to prevent the smartphone 40 from failing to acquire the information output by the blinking signal of the light 25a emitted by the smartphone 40.

In the alcohol measuring system 10, when the alcohol measuring device 20 includes a plurality of light emitting devices 25 as shown in FIG. 6, a part of the plurality of light emitting devices 25 blinking at the same timing with each other is measured by the alcohol measuring device 20. Even when it is covered by some object such as the hand of the person to be measured when it is grasped by a person, the blinking of the light 25a emitted by the uncovered portion is photographed by the camera 43, so that it is emitted by the light emitting device 25. It is possible to prevent the smartphone 40 from failing to acquire the information output by the blinking signal of the light 25a.

In the alcohol measuring system 10, the measuring device ID of the alcohol measuring device 20 and the measurement result information are notified from the alcohol measuring device 20 to the smartphone 40 at the same timing. However, in the alcohol measuring system 10, the measuring device ID of the alcohol measuring device 20 and the measurement result information may be notified from the alcohol measuring device 20 to the smartphone 40 at different timings.
