In this case, when the measurement start / end switch 10 of FIG. 2 is pressed, the measurement is started if the intake / drainage hole measurement lamp or the vent hole measurement lamp is lit, and if only the print lamp is lit, the buffer printing is performed. If both the intake hole measurement lamp and the ventilation hole measurement lamp are turned off, the initial value of the print data number is set. If the hole diameters of both the intake hole CT and the vent hole CR are not measured, the process proceeds to step S4 to select whether or not to perform printing. That is, when the measurement has already been completed and the measurement data is to be printed only, the printing is selected (step S4), and the buffer data is printed (step S6). Otherwise, if you do not select print, it will be in the special mode, the initial setting of the data number,

The reason why the spread state is set in this way is to bring the state close to a state where a normal baby sucks and drinks contents from a nipple.

After a lapse of a predetermined time, the solenoid valve 140, which is a measuring valve, is opened (step S12), and the solenoid valve 151, which is a drinking hole, is opened (step S12). S13). Thereby, the nipple C
Is supplied with air at a secondary pressure. In this case, the digital flow meter 7 receives a signal S1 relating to the amount of air flowing through the laminar flow tube LF. Thus, the digital flow meter 7 converts the nipple hole diameter corresponding to the measured flow rate of air. After reading the measurement data (step S14), the solenoid valve 140 as the measurement valve is closed, and the solenoid valve 151 as the drinking and drinking hole valve is closed (step S16).
