【Example】
Embodiments of the present invention will be described using the drawings. As a first embodiment, the case of measuring halitosis contained in exhalation, among odor components, will be described. FIG. 1 is a block diagram of a bad breath measuring device, FIG. 2 shows an appearance, and (a) shows a front side (b) shows a back side. A blowout port 3 is formed on the front side and a blowout port 4 is formed on the back side outside the case body 2 of the bad breath measuring instrument 1 and penetrates the inside of the case body 2. A switch 5 and a display unit 6 are also provided. This display unit 6 is used not only to indicate the measurement result but also to notify the waiting time during measurement standby and the consumption of the battery using a graphic. Inside the case body 2, a power source 7, a buzzer 8 and a CPU 9 that performs calculation and control, a battery storage unit, etc.
Semiconductor gas sensor 10 is arranged between the blow port 3 and Fukinuki hole 4. As this semiconductor gas sensor 10, it is generally used to cover the heater coil with a ceramic insulator and further cover the insulator with a semiconductor made of tin oxide (SnO ₂ ), so this is used Do. The structure and operation of this semiconductor gas sensor are described in Japanese Patent Application Laid-Open No. 1-35368, so they will not be described in detail here.

[0020]
The case of measuring the alcohol concentration will be described as a second embodiment. Also in the case of the alcohol concentration measuring instrument, the appearance is as shown in FIG. 4 and (a) represents the front side (b) the back side. The block diagram is omitted because it is configured in the same manner as the bad breath measuring device of the first embodiment. A blowout port 13 is formed on the front side and a blowout port 14 is formed on the back side outside the case body 12 of the alcohol concentration measuring instrument 11 and penetrates the inside of the case body 12. A switch 15 and a display unit 16 are also provided. The display unit 16 is used to indicate the measurement result and to notify of the waiting time in the measurement standby and the consumption of the battery . Case body 2 Power 7 therein, operation and buzzer 8, CPU for controlling, battery housing or the like is incorporated, the semiconductor gas sensor during the blow port 13 and the blow-hole 14 is disposed. As a semiconductor gas sensor, a semiconductor gas sensor in which a heater coil is covered with a ceramic insulator and the insulator is covered with a semiconductor made of tin oxide (SnO ₂ ) is also generally used as a semiconductor gas sensor in alcohol concentration detection. Use this.
