<P>PROBLEM TO BE SOLVED: To provide a droplet detecting device or the like which can count the correct number of droplets without the effect of ambient light and the like. <P>SOLUTION: The droplet detecting device 1 detects droplets. A light emitting section 10 emits intersecting light to a path through which droplets pass. A light receiving section 20 receives light emitted from the light emitting section 10 as input light and outputs a first signal 210 in response to the change in the input light. A droplet detecting section 30 detects droplets which pass between the light emitting section 10 and the light receiving section 20. The droplet detecting section 30 determines that a droplet has passed when it detects two extreme values of the first signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
