Second embodiment
The circuit theory diagrams of the time writer that Fig. 3 provides for the utility model second embodiment, present embodiment can first embodiment be the basis, power supply (Power) can adopt battery, for example common dry cell or rechargeable battery.The benchmark inductance L 1 and the reference capacitance C1 that are connected in parallel are connected among the feed circuit of battery, and further are connected with power control loop in the feed circuit of time writer, shown in frame of broken lines among Fig. 3.For obtaining the normal working voltage of time writer, for example 5 volts (V) usually needs the cell voltage processing of boosting.The basic structure of this power control loop comprises boosting unit, the first transistor Q3, transistor seconds Q2 and charge and discharge capacitance, and charge and discharge capacitance is three capacitor C 21, C22 and C23 that are connected in parallel in the present embodiment.
Boosting unit is communicated with benchmark inductance L 1 and reference capacitance C1 and feed circuit, can realize the conducting of battery and feed circuit when not having boost function.Be connected with an Enable Pin (ENB) on this boosting unit, the boost function of boosting unit is started working when Enable Pin (ENB) input enable signal.

Following mask body is introduced the principle of work of power control loop:
When time writer was in the state of not working, the positive pole of benchmark inductance L 1 and reference capacitance C1 can be described as the operating voltage utmost point (VCC), is communicated with the positive pole of battery by boosting unit.Specifically can be by a diode current flow in the boosting unit.This moment, base stage b and the emitter e of transistor seconds Q2 were electronegative potential, so transistor seconds Q2 disconnection, and then the collector c of transistor seconds Q2 is in noble potential.Simultaneously, the collector c of the first transistor Q3 is a noble potential, and emitter e is by a capacitor C 24 ground connection, therefore the first transistor Q3 disconnects, Enable Pin is a low level, and boosting unit does not have boost function, so can not drive benchmark inductance L 1 and reference capacitance C1 emission electromagnetic signal.
Be pressed as any control knob, in the time of corresponding gauge tap closure, the voltage of battery can be coupled to transistor seconds Q2 by resistance R 5 and resistance R 6, make transistor seconds Q2 conducting, thereby the base stage b current potential of the first transistor Q3 is dragged down, make the first transistor Q3 conducting, thereby the emitter e at the first transistor Q3 produces high level, the signal that makes Enable Pin is a high level, promptly imports enable signal, thereby opens the boost function of boosting unit.Meanwhile, three charge and discharge capacitance C21, C22 and C23 are recharged.
After opening the time writer operation, when not according to control knob, gauge tap disconnects, discharge by charge and discharge capacitance C21, C22 and C23 and to keep the conducting of transistor seconds Q2, this retention time can be determined by the capacitance of selecting charge and discharge capacitance C21, C22 and C23, for example the retention time can continue 20 minutes, perhaps the time span of other settings.At this section after the period, do not connect gauge tap if press control knob all the time, when charge and discharge capacitance C21, C22 and C23 discharge off, transistor seconds Q2 disconnects, and promptly is considered as time writer and quits work, and the first transistor Q3 disconnects immediately, Enable Pin is a low level, the boost function of boosting unit is closed, and benchmark inductance L 1 and reference voltage C1 no longer launch electromagnetic signal, thereby reach purpose of power saving.
In above-mentioned power control loop, can also comprise a low-voltage detecting unit, be connected in the feed circuit, specifically can integrate, be used to detect feed circuit with boosting unit, especially the voltage of battery is when the voltage of feed circuit sends cue during less than setting voltage value.For example ought detect cell voltage and drop to below the 0.9V, the low-voltage detecting unit can detect this low-voltage, can light a light emitting diode (Light Emitting Diode subsequently; Hereinafter to be referred as: LED), the prompting user changes battery.
Present embodiment has added power control loop in time writer, adopt the mode of active input pen, in the time of can solving passive input pen mode, and the intensive cost height of aerial array coil, and the antenna array strake needs continuous launching electromagnetic wave and the problem that consumes too much electric energy.By power control loop is set, can make time writer automatically cutting off power source when not working, avoid waste of energy, the work power consumption of making is lower than 1 milliampere (mA), for a joint alkaline battery, can use continuously more than 400 hours, avoid the user frequently to use the problem of battery instead.The foregoing circuit structural design is simple, and cost is low, and can corresponding reduce the required power consumption of antenna array strake one side, can reduce current consuming apparatus for portable product, makes product lightening.
Perhaps, power control loop also can adopt other modes to control power supply in the utility model, a vibroswitch for example is set, be connected in the feed circuit, when time writer was used, vibroswitch can detect the vibration of time writer and be kept closed, thereby made feed circuit conducting power supply, when time writer is placed when not using, then vibroswitch turn-offs feed circuit and economizes on electricity in the time can't recognizing vibration.
The concrete mode that changes the electromagnetic signal frequency has multiple, and for example, time writer can also be by reducing capacitance, increase or reduce inductance value, setting up the frequency that mode such as controlling resistance changes electromagnetic signal.
