As the embodiment of cartridge, it comprises housing, and the cavity by housing surrounds holds carbon dust in cavity, and a chip that has following with the chip embodiment characteristics that provide is installed on the outer wall of housing, and other structures are consistent with existing cartridge.
As the embodiment of print cartridge, then comprise housing, this housing surrounds the cavity that holds by ink, and a chip that has following with the chip embodiment characteristics that provide is installed on an outer wall of housing, and other structures are consistent with existing print cartridge structure.
Embodiment as chip, chip comprises a substrate, substrate is provided with a pair of electric contact 33,34, and be provided with the electronic module that is connected with this a pair of electric contact 33,34, the electrical schematic diagram of electronic module as shown in Figure 5, electronic module is connected with electric contact 33,34, and forms power circuit by resistance R 1, capacitor C 1, form modulation circuit by resistance R 6, R7, triode Q2, power circuit is consistent with the operation principle and the existing chip of modulation circuit.
The clock circuit of present embodiment comprises resistance R 2, R3 and voltage comparator G1, and an end of resistance R 3 is connected with electric contact 33, and the other end is connected to the Node B place, and an end of resistance R 2 is connected with electric contact 34, and the other end is connected to the Node B place.
Voltage comparator G1 is the voltage comparator that is integrated in the microcontroller 35, an one input is connected with Node B by the pin IO2 of microcontroller 35, another input is connected with reference voltage V ref, the reference voltage V ref of present embodiment is the reference voltage of microcontroller 35 inside, and the output of voltage comparator G1 provides clock signal to microcontroller 35.
Owing to have voltage drop between the electric contact 33 and 34, and the signal of the voltage waveform of this voltage drop for alternately changing, choosing the suitable resistance R2 of resistance, R3, can to make the voltage at Node B place be the signal that high-low level ground alternately changes waveform, form clock signal, for example Node B place voltage be 0.8 volt with 1.3 volts of clock signals that replace variation.
Simultaneously, select the reference voltage V ref of voltage suitable in the microcontroller 35 as voltage comparator G1, for example selection reference voltage Vref is 1 volt.Since the Node B place to the clock signal level of voltage comparator G1 input in the conversion of reference voltage V ref alternatively up and down, the output of voltage comparator G1 will export high level and low level replaces the clock signal that changes, and this clock signal is offered microcontroller 35 uses.
When modulation circuit is modulated the signal of electric contact 33 outputs, the voltage of electric contact 33 will reduce by 0.3 volt, and the voltage of electric contact 34 is constant, because the dividing potential drop effect of electronics R2, R3, Node B place voltage will reduce by 0.1 volt accordingly, become checker between 0.7 volt and 1.2 volts.Because the clock signal of Node B place input is still in the conversion of reference voltage V ref alternatively up and down, the signal of voltage comparator G1 output still is the clock signal that high level and low level alternately change, and the amplitude of level is with original consistent, like this, when even modulation circuit is modulated the signal of electric contact 33 outputs, the voltage waveform of voltage comparator G1 output can not change, and can guarantee that microcontroller 35 carries out work under identical clock signal.
This shows, even the clock signal of Node B place input is received interference, the clock signal of voltage comparator G1 output still can not change, and effectively avoids modulation circuit that the clock signal of microcontroller 35 is caused interference, and microcontroller 35 is worked under the stable clock signal.
Certainly, voltage comparator G1 not necessarily is integrated in the voltage comparator in the microcontroller, also can use the external voltage comparator, simultaneously, the reference voltage of voltage comparator also can the time use the level signal of external setting-up, these change does not influence realization of the present utility model.
Equally, the voltage comparator G1 that the foregoing description uses is a desirable voltage comparison unit, and during actual the use, the voltage comparison unit that can also use discrete component to form is realized voltage ratio, and this can realize the purpose of this utility model equally.
It is emphasized that at last the utility model is not limited to above-mentioned embodiment, also should be included in the protection domain of the utility model claim as the change of circuit construction of electric power, the small variations such as change of number of electrical contacts.
