If it is determined that the state where 0 has been maintained in a substantially horizontal state has been continued for a certain period of time (YES in step 133), cumulative display of measured values is performed (step 134). This is because the accumulated measurement value up to that time is stored in the processing of step 136 described later, and the stored accumulated measurement value is stored in step 13.
This is a process of adding and displaying the current measurement values measured in the processes of steps 1 to 133. Note that the first time after the cumulative measurement value is reset is step 131 to step 133.
Is displayed as it is.

Next, it is checked whether or not a process for resetting the cumulative calculation of the measured values has been performed (step 135).
The reset process is performed when the accumulated measurement value displayed in the process of step 134 reaches near the target value.
For example, this is performed by pressing a reset button.

Therefore, when the reset processing is performed after the accumulated measured value displayed in the processing of step 134 has reached the vicinity of the target value (YES in step 135), this processing ends.

If the cumulative measured value displayed in the processing of step 134 does not reach the vicinity of the target value and the reset processing is not performed (NO in step 135), step 134
Is stored (step 136), and the process returns to step 131.

FIG. 10 shows a display example of the present embodiment. For example, when it is desired to put 10 g of foodstuff into a certain container, the first time, 5 g of scooping, and then 4 g of scooping, are displayed. This is an example. In this case, after the first insertion, as shown in FIG.
g "is displayed, and after the second insertion," 9g "is displayed on the display unit 21 as shown in FIG. Therefore, the spoon user knows that another 1 g should be added next time.
