PROBLEM TO BE SOLVED: To provide an exhalation switch device which achieves an easier handling with a higher operability. SOLUTION: A message indicating a display of intent is shown circularly at an specified time interval on a message display part 12A and a user blows his exhalation to a carbon dioxide sensor 11A at the timing of receiving a desired message on display while viewing it to allow the generation of an external control signal corresponding to the contents of the message. The control of announcing and switching is accomplished corresponding to the contents of the message in response to the external control signal. Especially, the carbon dioxide sensor 11A and the message display part 12A are housed closer to each other inside a cup-shaped exhalation collection part 1A for collecting exhalation having a circular open part so as to look outward from the circular open part thereby improving the visual recognition of the message while achieving more effective collection of the exhalation. |
