Next, a third embodiment of the present invention will be described with reference to FIG. 10, only the differences from the first and second embodiments.

That is, in this case, based on the situation set by the user in step B9 instead of the previous step A9,
It is determined whether the remaining time of the execution content in the first tank 2 is shorter than that of the execution content in the second tank 3. If it is determined that the remaining time is shorter than that of the execution content in the second tank 3, then the display section 16 ~24.42
is switched to display the content of execution in the second tank 3 with the shortest remaining time (step B10). After that, step Bll and step A similar to the previous step All.
Step B12 similar to step B12 is performed.

In addition, if it is determined in step B9 that the remaining time of the execution content in the first tank 2 is not shorter than that of the execution content in the second hinoki 3, the remaining time is shorter in the second tank. 3, the display units 16 to 24.42 are then switched to display the content of execution in the second tank 3, which has the shortest remaining time (
Step B13) However, in this case as well, after that,
Step B14, which is similar to step A14, and step B15, which is similar to step A15, are executed.

Further, the above display switching is also performed in the same way when either tank 2 or 3 is in operation, if the "tank switching" switch 41 is operated.

In addition, steps B1 to B8 are the previous step A.
