Preferred nylon tape 4 main body, in white, has density bullet section 5 with plastic housing 2 abutting edge, at the density bullet band 6 of the long section of end Duan Youyi.Mark detecting apparatus 11 detects the density bullet section 5 on nylon tape 4, guarantees that device only peels off a test paper at every turn; Mark detecting apparatus 11 detects the density bullet band 6 in the section of nylon tape 4 end, whether is in blank panel state with Test paper dish 8.
Button 16 comprises starting key, shutdown button and clicks gets paper button, contains start, shuts down, clicks and get paper function.
The specific embodiment of the invention course of work is as follows:
Casing is rectangle, has two chambers, a right-angled trapezium chamber and a triangular chamber.Be placed with control circuit, button and pilot lamp in triangular chamber, be placed with in trapezoidal chamber and throw various parts needed for paper and test paper disk.
Nylon tape 4 main body of embodiment is white, and have density bullet section 5 with plastic housing 2 abutting edge, the indicia band 6 of nylon tape 4 end is the density bullet band of long section, and length comparatively density bullet section 5 is long.
After the test paper band be wrapped in advance on test paper disk strides across guide wheel, the effect of powered machine travel power, separated guide is separated into three parts.Wherein, test paper is sent from separation guide proximal outlet, and plastic housing is sent from separation guide distal outlet port, and nylon tape is wrapped on nylon tape godet under the effect of motor.
When using of the present invention, long button, key press detecting circuit detects the then device start of this special key form, and after start, pilot lamp lighted by single-chip microcomputer.After start, if key press detecting circuit detects click button form, then enable and get paper function.After clicking button, single-chip microcomputer sending controling instruction is to motor drive module, motor drive module drive motor rotates and also drives test paper disk to rotate by nylon tape, and the plastic housing on test paper band and test paper are progressively separated being separated under guide effect, and are directed to different delivery outlets.Turn-on flag pick-up unit after single-chip microcomputer time delay certain hour, the infrared-emitting diode in mark detecting apparatus launches infrared light, and infrared photosensitive reception diode detects whether receive reflects infrared light in real time.When the white main part of nylon tape moves near mark detecting apparatus, the infrared light that the white main part reflective infrared emitting diode of nylon tape is launched, the infrared light of this reflection receive by infrared photosensitive reception diode and send into mark detecting signal processing module and process.Comparer output low level now in mark detecting signal processing module sends into single-chip microcomputer, and motor is rotated further, and the plastic housing on test paper band and test paper continue to be separated and send.When density bullet section 5 between adjacent plastic housing 2 moves near mark detecting apparatus, the infrared light that infrared-emitting diode sends absorb by density bullet section, infrared photosensitive reception diode is without reception.Comparer now in mark detecting signal processing module exports high level and sends into single-chip microcomputer, and trigger singlechip interruption, single-chip microcomputer performs interrupt routine and sending controling instruction makes motor stalls, and the plastic housing now on test paper band and test paper have been separated complete and have sent from corresponding delivery outlet.
If when having test paper in test paper disk, mark detecting apparatus can only detect white main part and the density bullet section of nylon tape.And according to above-mentioned explanation, turn-on flag pick-up unit after single-chip microcomputer time delay a period of time, it should detect the white main part of nylon tape.If but when not having test paper in test paper disk, when turn-on flag pick-up unit after single-chip microcomputer time delay a period of time, it can only detect the density bullet band of nylon tape, different from state when having test paper in test paper disk, then illustrate that in test paper disk, test paper is used up.Then Single-chip Controlling pilot lamp flicker, reminding user to replace test paper disk.After changing test paper disk, click button, come again and get paper process, pilot lamp stops flicker.After getting paper, long button, key press detecting circuit detects the then device shutdown of this special key form.
Above-mentioned embodiment is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
