Triggering singlechip interruption, single-chip microcomputer execution interrupt routine sends control instruction and leaves the motor off rotation, now on reagent paper band
Plastic housing is separated with reagent paper to be finished and sends from corresponding delivery outlet.
If have reagent paper in test paper disk, mark detecting apparatus are only able to detect white main part and the black mark of nylon tape
Note section.And as specified above, turn-on flag detection means after single-chip microcomputer time delay for a period of time, it should detect nylon tape
White main part.If but when there is no reagent paper in test paper disk, when single-chip microcomputer time delay for a period of time after turn-on flag detection means,
It is only able to detect the density bullet band of nylon tape, different from there being state during reagent paper in test paper disk, then examination in explanation test paper disk
Paper has been used up.Then Single-chip Controlling display lamp flicker, reminds user to change test paper disk.After changing test paper disk, click button, weight
Take paper process again for one time, display lamp stops flicker.After taking paper to finish, long button, it is special that key press detecting circuit detects this
The then device shutdown of button form.
Above-mentioned specific embodiment is used for illustrating the present invention, rather than limits the invention, the present invention's
In spirit and scope of the claims, any modifications and changes that the present invention is made, both fall within the protection model of the present invention
Enclose.
