Abstract

When an electronic timepiece is in the power-saving mode for stopping indication of the present time, it is decided whether the charging voltage fed from a large capacitor (48) is higher or lower than a predetermined reference voltage. If it is higher, the large capacitor has stored the electric power necessary for returning from the power-saving mode to the indication mode; therefore, when power generation is detected, the present time-return processing is effected. On the other hand, if the charging voltage is lower than the predetermined reference voltage, supply of the power source voltage to a control circuit is stopped, thereby suppressing wasteful consumption of the electric energy stored in the large capacitor. This ensures that when the power generator starts generation of power, the electronic timepiece is quickly restarted.

Power supply produces state-detection part 91, according to produce the power supply that equipment 40 produces by power supply, produce the power supply generation state of equipment 40 and the running status of amplitude limiter circuit LM according to power supply, distinguish whether the charging for high power capacity accessory power supply 48 has produced enough power supplys.And output has the power supply that produces the frequency in cycle according to power supply and produces and detect data DDET to central control circuit 93.

Then, will other distinctive circuit structures that power supply produces state-detection part 91 be described with reference to figure 3.This power supply produces state detection circuit part 91 and comprises transistor 91A, 91B, and pull down resistor 91C detects phase inverter 91E and charging current testing circuit DET.Transistor 91A and transistor 91B are at the signal wire of the voltage Vdd with hot side and have between the signal wire of low potential side voltage Vss and connect.Pull down resistor 91C is connected to the two ends of capacitor 91B.Detection phase inverter 91E is connected to the tie point 91D between transistor 91A and the capacitor 91B.Charging current testing circuit DET is connected between the positive side and Vdd of high capacity capacitor 48.

When power supply produces electric current when rectification circuit 47 flows to high capacity capacitor 48, electric current also flows to charging current testing circuit DET.For example, when charging current testing circuit DET is constituted by a diode, produce forward voltage VF.As this forward voltage VF during greater than the threshold voltage vt h of transistor 91A, transistor 91A is switched on, and capacitor 91B is recharged.And, when the voltage VA of tie point 91D from low potential side voltage Vss during near hot side voltage Vdd, this state is remained to a certain degree by pull down resistor 91C, and the current potential of voltage VA surpasses the threshold value that detects phase inverter 91E thus, and output switches to " H " from " L ".

Produce state-detection part 91 by forming power supply in this way, to be explained is provided with magnitude of voltage V0 and time value T0 is set by suitably selecting the threshold voltage vt h of transistor 91A, the threshold value of pull-down-resistor 91C and detection phase inverter 91 is provided with, so that detect the power supply generation state that power supply produces equipment 40.

Then, be satisfied if the condition of first testing circuit 97 and second testing circuit 98 produces in the state-detection part at power supply, power supply produces part A and is determined the power supply generation state that is in.Therefore, when Vdd (=GND) got when for referencial use, it is negative voltage that magnitude of voltage V0 is set, and indicates the voltage difference with Vdd.

Thereby, the used magnitude of voltage V0 that is provided with is by the value of setting switching part 95 switching controls in first testing circuit 97, when display mode was switched to the power supply save mode, the value of setting switching part 95 changed the used magnitude of voltage V0 that is provided with in first testing circuit 97.Just, in this example, it is Va that magnitude of voltage is set in display mode, and it is Vb that magnitude of voltage is set in the power supply save mode, and their relation is set to Va＜Vb.Therefore, need produce sizable power supply in order to switch to display mode from the power supply save mode.The value of setting switching part 95 is also finished and is switched in the used time value T0 that is provided with in second testing circuit 98.

At this, the example of a voltage detecting circuit 92 will be described with reference to Figure 11.

Voltage detecting circuit 92 comprises resistor R 1, R2, and reference voltage produces part 92A, comparer 92B, a P channel MOS transistor 92C and the 2nd P channel MOS transistor 92D.Resistors in series R1 and R2 distribute the voltage between hot side power vd D and the low potential side power supply VSS with the voltage distribution ratio of predesignating, detect voltage VDET to produce.Reference voltage produces part 92A and produces the reference voltage VREF that predesignates from hot side power vd D.Comparer 92B makes comparisons detection voltage VDET on the tie point between resistor R 1 and the resistor R 2 and reference voltage VREF, and output voltage detects data DV to central control circuit 93.The one P channel MOS transistor 92C is connected by the sampled signal SP (being in level " L " when detecting) from central control circuit 93 outputs in the voltage detecting timing, the Enable Pin EN of comparer 92B is placed level " H ", is mode of operation so that put comparer 92B.

When the sampled signal SP of " L " level when central control circuit 93 is input to voltage detecting circuit 92, a P channel MOS transistor 92C and the 2nd P channel MOS transistor 92D are switched on.

As a result, power supply is supplied to resistor R 1, R2, and resistor R 1, R2 distributes the voltage between hot side power vd D and the low potential side power supply VSS by the allocation proportion of predesignating, detect voltage VDET to produce, and is applied to the inverting input of comparer.

On the other hand, the Enable Pin EN of comparer 92B also arrives " H " level, and comparer 92B will detect voltage VDET and reference voltage VREF makes comparisons, and output voltage detects data DV to central control circuit 93 then.

In addition, central control circuit 93 comprises not generation time metering circuit 99 of power supply, be used to measure not generation time Tn of power supply, during this period at testing circuit 97, not detecting power supply on 98 produces, if power supply not generation time Tn continues, will finish switching (first condition) so from display mode to the power supply save mode in the set time cycle that at least one is predesignated.

On the other hand, when detecting power supply generation part A, power supply generation state-detection part 91 is in the power supply generation state, enforcement returns to display mode from the power supply save mode, and enough electric energy are retained among the charging voltage Vc of high capacity capacitor 48 so that get back to display mode (first condition) from the power supply save mode.

Yet, if amplitude limiter circuit is in operation (connection) in the power supply save mode, then form and be different from the short circuit that charges normal branch road, thereby power supply produced the part A short circuit, make when power supply generation part A is in power supply generation state, power supply produces state-detection part 91 and can not detect, thereby can not transfer display mode to from the power supply save mode.

Therefore, in the present embodiment, when being in the power supply save mode,, power supply how produces state no matter producing the power supply of part A, amplitude limiter circuit is disconnected (opening), and power supply produces state-detection part 91 can detect the power supply generation state that power supply produces part A reliably.

In addition,,, utilize voltage liftings/decline circuit 49,, can drive the CS of pen travel mechanism, CHM by the lifting supply voltage even a little is a little low for charging voltage Vc because the power pack B of the present embodiment comprises voltage lifting/decline circuit 49.

On the other hand, if a little height of charging voltage Vc is a bit, be higher than the CS of pen travel mechanism, the driving voltage of CHM utilizes voltage lifting/decline circuit 49, and supply voltage is descended, the CS of pen travel mechanism, and CHM can be driven by the supply voltage that reduces.For this purpose, central control circuit 93 is determined voltage lifting/decline factor according to charging voltage Vc, with control voltage lifting/decline circuit 49.

Yet,,, also can not obtain the operation pen travel CS of mechanism, the supply voltage that CHM is enough even voltage is raised if charging voltage Vc is too low.If under such a case, carry out transfer from the power supply save mode to display mode, can not realize that correct time shows that power supply has unnecessarily been consumed.

Therefore, in the present embodiment, by charging voltage Vc and the predetermined magnitude of voltage Vb that is provided with are made comparisons, determine whether that charging voltage Vc is enough, this just constitutes the first condition that shifts from the power supply save mode to display mode.

And, central control circuit 93 comprises power supply save mode counter 101, if external input device 100 is operated by the user, if perhaps power supply does not produce state and produced test section 91 by power supply and detect, counter is used to monitor and whether is used for forced branch and operates to the prepositioned instruction of power supply save mode and implement in the time of predesignating.

The pattern of She Zhiing is stored in the mode memory part 94 in this way, and this information is provided for Drive and Control Circuit 24, temporal information memory portion 96 and the value of setting switching part 95.

At this, when switching to the power supply save mode from display mode, Drive and Control Circuit 24 end with control signal supply with second hand drive part 30S and the time-minute hand drive part 30HM.As a result, motor 10,60 stops the rotation, thereby the intermission shows.

And, central control circuit 93 has the function of operation abortion means, when having become to be lower than, supply voltage predesignates, for when the power supply save mode returns the necessary electric weight of display mode by step described below, be used for ending voltage from power pack B supply control circuit 23 and drive part 30S, 30HM.

Then, by means of this step,, can be reduced from the discharge of high capacity capacitor 48, thereby eliminate unnecessary charge consumption widely even be retained in the high capacity capacitor 48 so that when the power supply save mode returns display mode when enough electric energy.

Then, temporal information memory portion 96 is made up of a up-down counter (not shown) than more particularly, make after switching to the power supply save mode from display mode, the reference signal that reception is produced by pulse combiner circuit 22, the beginning Measuring Time, increment count value (going up counting), and the duration of measuring the power supply save mode as count value.

In addition, when when the power supply save mode switches to display mode, up-down counter is count value decrement (counting down), during counting down, the acceleration pulse that output is supplied with from Drive and Control Circuit to second hand drive part 30S and the time-minute hand drive part 30HM.

Then, when the count value of up-down counter arrives zero, just the duration of power supply save mode and with the pin that is accelerated move the required time corresponding to be accelerated the pin traveling time over and done with, generation is used to end to transmit the control signal of acceleration pulse, this control signal be supplied to second hand movable part 30S and the time-minute hand drive part 30HM.As a result, time showing is returned to the current time.In this way, temporal information memory portion 96 also has the function of current time recovery device part, and the time showing that is used for being shown again returns to the current time.

Then, according to all kinds of the pulse of exporting from pulse combiner circuit 22, Drive and Control Circuit 24 is according to the mode producing driving pulse.At first, in the power supply save mode, the supply of driving pulse is ended.Then, and then after switching to display mode from the power supply save mode, acceleration pulse with short recurrent interval be used as driving pulse supply with second hand drive part 30S and the time-minute hand drive part 30HM so that the time showing that will show again returns to the current time (current time recovery device).

Then, after the supply of acceleration pulse is finished, normal burst driving pulse at interval be supplied to second hand drive part 30S and the time-minute hand drive part 30HM.

Reference number 120 marks are by an angular-rate sensor, the delivery status testing circuit that a thermal sensor etc. are formed, wherein delivery status testing circuit 120 detects whether electronic watch 1 is by on user's wrist, and whether power supply generation equipment 40 is to be in the power supply generation state so that detect indirectly.In addition, delivery status testing circuit 120 is provided by the non-delivery time test circuit 121 that provides in central control circuit 93.This non-delivery time metering circuit 121 is measured the non-time that is transmitted, and is similar to the not result of generation time metering circuit 99 of power supply described above roughly.

At this, delivery status testing circuit 120 and non-delivery time metering circuit 121 are used to substitute electric power and produce not generation time metering circuit 99 of state-detection part 91 and power supply.

[3] operation of embodiment

Operation steps according to electronic watch 1 of the present invention will make an explanation with reference to figure 4.

At first, control circuit 23 judges whether that electronic watch 1 is to be in (step S1) in the power supply save mode.If in the judgement of step S1, electronic watch 1 is found and is in (step S1 in the power supply save mode; Be), step jumps to the following step S5 that will describe so.

Otherwise,, just be in display mode (step S1 if the judgement of step S1 finds that wrist-watch is not in the power supply save mode; Not), central control circuit 93 has determined whether supply voltage so, and just whether according to producing condition detecting device 91 detected signals from power supply, power supply produces equipment 40 and producing power supply (step S2).If determine in step S2, it is to be in the power supply generation state that power supply produces equipment 40, so according to the following step S10 execution time step display that will describe.

If power supply generation equipment 40 is found and is in (step S2 in the non-generation state in step S2; Not), so, by 99 pairs of non-generation time Tn countings of non-generation time metering circuit (step S3) of central processing circuit 93.Then, central processing circuit 93 determines whether non-generation time Tn time that is provided with (step S4) by predesignating continuously.

In the judgement of step S4, if non-generation time Tn is the not continuous time that is provided with (step S4 by predesignating; Not), step is returned to step S2 so, and the step from step S2 to step S4 is repeated.

If in the judgement of step S4, non-generation time Tn is found the time that is provided with (the step S4 by predesignating continuously; Be), pattern is switched to power supply save mode (step S5) so.

On the other hand, in the power supply save mode, in temporal information memory portion 96, be counted (step S6) corresponding to the temporal information of time of passing through of power supply save mode, so that the time rejuvenation (step S9) that will describe below carrying out.

Then, determine whether that supply voltage (in the present embodiment, the charging voltage Vc of high capacity capacitor 48) is greater than switch to the required criterion voltage V1 (step S7) (second condition) of display mode from the power supply save mode.If find that in step S7 charging voltage Vc is greater than criterion voltage V1 (step S7; Be), just may turn back to display mode from the power supply save mode, determine whether that then power supply produces equipment 40 and producing power supply (step S8) once more.If in step S8, determine, do not produce power supply (step S8; Not), step S6 and S7 are repeated so.

Otherwise, in step S8, find power supply generation beginning the (step S8; Be), pattern is switched to display mode from the power supply save mode so, and the time rejuvenation that is used for the time is returned to the count value of temporal information memory portion 96 is performed, pointer 55,76,77 are driven (step S10) by common mode.Time rejuvenation from the power supply save mode to display mode is the rejuvenation of a current time, carries out faster than normal driving operation.

On the other hand, if in step S7, find that the charging voltage Vc of accumulation in high capacity capacitor 48 is less than or equal to criterion voltage V1 (step S7; Not), just the charging voltage Vc of high capacity capacitor 48 has dropped into the voltage that can not recover display mode from the power supply save mode, so, from the charging voltage Vc of high capacity capacitor 48 supplies providing of voltage lifting/decline circuit 49 is cut off, from the supply voltage of voltage lifting/decline circuit 49 output Vss drive part 23A to control circuit 23, pulse combiner circuit 22 and drive part 30S, the supply of 30HM is cut off (step S11).

In step S11, by cutting off the Vss drive part 23A of supply voltage Vss to control circuit 23, pulse combiner circuit 22 and drive part 30S, the supply of 30HM, pulse combiner circuit 22 stops to produce pulse signal, and temporal information memory portion 96 is ended counting.As a result, the power consumption in control circuit 23 becomes zero.For example, the power consumption rate can deduct about 80% with respect to the electrical source consumption in the display mode in the power supply save mode, but in this state, can further cut down 99.5%, in addition, in Vss drive part 23A, have only power supply to produce the supply that state-detection part 91 is not cut off supply voltage Vss.By supply voltage Vss without interruption, but the operation of stabilizing circuit when activating again.

And in step S12, power supply produces state-detection part 91 and monitors whether power supply produces the generation (the 3rd condition) that equipment 40 has recovered power supply, step S12 be held up to power supply produce state-detection part 91 detect power supply produce begun till.

At this,, power supply generation state-detection part 91 recovers (step S12 when detecting the power supply generation; Be), charging voltage Vc from high capacity capacitor 48 is applied to voltage lifting/decline circuit 49, supply voltage Vss is supplied with Vss drive part 23A from voltage lifting/decline circuit 49, pulse combiner circuit 22 and drive part 30S, and 30HM is so that active electron clock and watch 1 again.

In this step S12, the charging voltage Vc of high capacity capacitor 48 is detected from voltage detecting circuit 92, exist for activating required minimum voltage again determining whether, the supply of charging voltage Vc is ended till this magnitude of voltage is reached, thereby high capacity capacitor 48 can be charged quickly.

In addition, in this case, time rejuvenation can not be implemented, because control circuit 23 also ended, thereby needs the user that the time manually is set.

And, utilize more concrete digital value to make an explanation, under common technical conditions, the charging voltage Vc of high capacity capacitor 48 is lowered to about 0.45V, be placed to full-charge state from high capacity capacitor 48 after power supply generation beginning, electronic watch 1 must rock about 300 times.Yet, in the present embodiment, criterion voltage V1 is set to 1V, thereby charging voltage is difficult to drop into below the 1V, so produce for high capacity capacitor 48 is placed into full-charge state from the beginning power supply, rock electronic watch 1 about 100 times just enough, electronic watch is activated easily again.

[4] effect of embodiment

As explained above, the electronic watch 1 of the present embodiment is such, when electronic watch 1 is in the power supply save mode, just charging voltage Vc outputs to voltage lifting/decline circuit 49 from high capacity capacitor 48, by voltage lifting/decline circuit 49, only be supplied to control circuit 23 from the supply voltage Vss of charging voltage Vc lifting or decline, if being less than or equal to from the power supply save mode, the charging voltage Vc of high capacity capacitor 48 turns back to the required criterion voltage V1 of display mode, charging voltage Vc from high capacity capacitor 48 outputs is ended the supply of voltage lifting/decline circuit 47 so, from the supply voltage Vss of power pack B (voltage lifting/decline circuit 47) drive part 23A to control circuit 23, pulse combiner circuit 22 and drive part 30S, the supply of 30HM is ended.

Thereby the unnecessary consumption of electric energy can be eliminated in high capacity capacitor 48, and charging voltage Vc can be maintained in the high capacity capacitor 48.As a result of, when power supply generation equipment 40 begins to produce power supply, the charging voltage Vc of high capacity capacitor 48 can be output to voltage lifting/decline circuit 49, thereby supply voltage Vss is by the Vss drive part 23A from voltage lifting/decline circuit 49 supply control circuits 23, pulse combiner circuit 22 and drive part 30S, 30HM is so that active electron clock and watch 1 again apace.

In addition, by the unnecessary consumption of charging voltage Vc of compacting high capacity capacitor 48, when the user carries electronic watch 1, when power supply generation equipment 40 begins to produce power supply, pointer 55 can be activated apace, prevents that like this user from jumping, and electronic watch is damaged as a result.

[5] the modification example of embodiment

[5.1] first revise example

First revise in example at this, as shown in Figure 5, the voltage of supplying with pressure regulation driving circuit 200 (for example pierce circuit, frequency dividing circuit etc.) is to produce the regulation voltage Vreg that circuit 201 is provided with by pressure regulation.

At this, will describe pressure regulation and produce circuit 201.

Pressure regulation produces the structural diagrams of circuit 201 in Figure 12.

Pressure regulation produces circuit 201 mainly can be divided into constant current source 220, the first current mirror circuitry phases 221, and differential amplifier circuit 222, the second current mirror circuitry phases 223 and pressure regulation produce part 224.Constant current source 220 is buffer transistors etc., produces constant current IREF.The first current mirror circuitry phase 221 produces the electric current identical with constant current IREF.Differential amplifier circuit 222 is realized reference voltage V1 and is flow through the difference amplification of the voltage V2 of generation as constant current IREF.The second current mirror circuitry phase 223 makes the electric current that flows in differential amplifier circuit 222 each several parts become constant current.Pressure regulation produces output generation and the output regulation voltage of part 224 according to differential amplifier circuit 222.

The first current mirror circuitry phase 221 has P channel MOS transistor MP1, and MP2 and MP3, their source S link hot side power vd D and the door end G that is connected in together jointly, and the grid G of P channel MOS transistor MP1 is connected by saturated with leakage D.

Differential amplifier circuit 222 comprises P channel MOS transistor MP4, and P channel MOS transistor MP5 and door current potential keep capacitor CGK.P channel MOS transistor MP4 has the source S of the leakage D that links P channel MOS transistor MP2 and links the door G of the leakage D of P channel MOS transistor MP1.P channel MOS transistor MP5 has the source S of its leakage D that links P channel MOS transistor MP2 and links the door G of the leakage D of P channel MOS transistor MP3.The door current potential keeps capacitor CGK to have an end of the leakage of linking the P channel MOS transistor).

The second current mirror circuitry phase 223 comprises N-channel MOS transistor MN3 and N-channel MOS transistor MN4.N-channel MOS transistor MN3 has the leakage D of the leakage D that links P channel MOS transistor MP4 and links the source S of low potential side power supply VSS side.N-channel MOS transistor MN4 has its door G that links the door G of N-channel MOS transistor MN3, and it leaks D links the leakage of P channel MOS transistor MP5 and the door G of N-channel MOS transistor MN3, and its source G links low potential side power supply VSS side.

Pressure regulation produces part 224 and comprises N-channel MOS transistor MN1 and N-channel MOS transistor MN2.N-channel MOS transistor MN1 has the saturated door G that it leaks D that is connected to, and it leaks the leakage D that D links P channel MOS transistor MP3, and its source S links the other end that a current potential keeps capacitor C GK.N-channel MOS transistor MN2 has the leakage of the source S that links N-channel MOS transistor MN1, its source S links low potential side power supply VSS, its G links the end that a current potential keeps capacitor C GK, in addition, the tie point between the leakage of the source S of N-channel MOS transistor MN1 and N-channel MOS transistor MN2 is the output terminal of regulation voltage VREG.

Down, will the operation that pressure regulation produces circuit 201 be described.

The first current mirror circuitry phase 221 produces the electric current (in the drawings, by identical reference IREF represented) identical with constant current IREF, and this electric current is produced by constant current source 220, as source-leakage current of P channel MOS transistor MP3, supplies with pressure regulation and produces part 224.

At this moment, can be expressed as follows at the leakage current Ids of P channel MOS transistor MP1 and the relation between the gate voltage:

Ids＝β·W/(2·L)·(Vgs-Vth) ²

At this, β represents gain constant.

Corresponding therewith, differential amplifier circuit 222 is carried out the difference of reference voltage V1 and voltage V2 and is amplified, and outputs to pressure regulation generation part 224.

At this moment, source-leakage current of P channel MOS transistor MP4 and P channel MOS transistor MP5 have with because the second current mirror circuitry phase causes identical current value.

Pressure regulation produces the FEEDBACK CONTROL that part 224 realizes differential amplifier circuit 222 outputs, makes reference voltage V1 and reference voltage V2 be:

V1＝V2

As a result, by the definite regulation voltage Vreg of the threshold voltage VTP of the P channel MOS transistor MP1 that forms the first current mirror circuitry phase 221, threshold value VTN and constant current IREF that pressure regulation produces the N-channel MOS transistor MN1 of part 224 are produced.

When supplying with pressure regulation driving circuit 200 (pierce circuit for example, frequency dividing circuit etc.) voltage is when producing the regulation voltage Vreg that circuit 201 is provided with by pressure regulation, and the p channel transistor 203 that the operation abortion means that separates from central control circuit 93 is made up of latch cicuit 202 and is connected between the mid point of the outgoing side of latch cicuit 202 and hot side Vdd line is between high capacity capacitor 48 and central control circuit 93.When hot side voltage Vdd was got voltage for referencial use (GND), low-potential voltage Vss became supply voltage, and potential difference (PD) becomes and equals charging voltage Vc.

In addition, pierce circuit and divider circuit are driven by the regulation voltage Vreg that produces circuit output from pressure regulation.

Like this, during the power supply save mode, central control circuit 93 is by voltage detecting circuit 92 monitoring supply voltages (the charging voltage Vc of high capacity capacitor 47), when voltage drop to the value of predesignating when following output " L " to latch cicuit 202.Then, at latch cicuit 202, receive from power supply and produce the signal of state-detection part 91 outputs and the signal of exporting from central control circuit 93, export the signal that transistor 203 is placed into " H ", transistor 203 is placed in off-state.Then, the charging voltage Vc of high capacity capacitor 48 is to central control circuit 93, voltage detecting circuit 92, and the supply that pressure regulation produces circuit 201 grades is cut off.As a result, when receiving charging voltage Vc, the regulation voltage Vreg that produces circuit 201 outputs from pressure regulation is ended, and the operation of pressure regulation driving circuit 200 is ended.

And, in the power supply save mode, drive part 30S, 30HM is ended, most of electrical source consumption is by pressure regulation driving circuit 200 on circuit, as be used to produce the pierce circuit and the divider circuit of reference burst signal, and pressure regulation generation circuit 201 consumes, so give pressure regulation driving circuit 200 by ending supply regulation voltage Vreg, electrical source consumption on pressure regulation driving circuit 200 can reduce to zero, and, producing circuit 201 by ending supply supply voltage Vss to pressure regulation, the electrical source consumption of entire circuit can be near zero.

In addition, the power supply generation begins on power supply generation part A when power supply generation state-detection part 91 detects, input signal " H " is to latch cicuit 202, transistor 203 becomes off-state, charging voltage Vc is supplied to central control circuit 93, voltage detecting circuit 92 and pressure regulation produce circuit 201.Because when starting of oscillation, enough voltage is maintained in the high capacity capacitor 48, and the startup of vibration can be accelerated.Therefore, electronic watch 1 can be activated easily again.

When transistor 203 is placed to off-state, when the supply of supply voltage Vss was ended, it is unstable that the output of latch cicuit 202 becomes.Therefore, it is distolateral that the pullup resistor with high value preferably should be linked the door of transistor 203, to guarantee that transistor 203 is in off-state.

[5.2] first revise example

Revise in the example first, transistor 203 is linked to be supplied with on the circuit that hot side voltage Vdd passed through, so that cut off the electric current of being supplied with.Therefore, revise in the example, must use to have quite jumbo transistor 203 first.Like this, revise in the example, can reach same effect by the operation abortion means of forming as shown in Figure 6 second.

Pierce circuit 301, divider circuit 302 and level shifter 303 are the detailed characteristics by the pressure regulation driving circuit 200 of regulation voltage Vreg driving.In addition, revise in the example at this, the circuit with hot side voltage Vdd is made reference line a, and the circuit with low potential side voltage Vss is made the b of supply line, and the circuit with regulation voltage Vreg of constant potential is made voltage regulating line c.

At this, P channel transistor 304 is connected between circuit a and the c, and P channel transistor 305 is connected between circuit b and the regulating circuit 92, and the door of transistor 305 is linked the outgoing side of central control circuit 92.In addition, the door of transistor 304 is linked the outgoing side of central control circuit 92.Transistor 304 and transistor 305 are formed the operation abortion means.

Utilize the circuit arrangement of the second modification example of forming by this way, when electronic watch 1 is in the power supply save mode, power supply produces the power supply generation state that state-detection part 91 monitoring power supplys produce part A, when power supply produced part and enters non-power supply and produce state, output " L " signal was to transistor 304 and transistor 305.As a result, transistor 304 enters on-state,, thereby cuts off to pierce circuit 301 the regulation voltage reg of divider circuit 302 and level shifter 303 power supplies with reference line a and voltage regulating line c short circuit.In the identical time, " L " signal is imported into transistor 305, and transistor 305 is placed into off-state substantially, cuts off the charging voltage Vc that exchanges living circuit 92 power supplies of cutting down output from high capacity capacitor 48, also cuts off the power supply to regulation voltage Vreg.

Otherwise, when power supply generation beginning,, thereby disconnecting transistor 304 from central control circuit 93 output " H " signals, connection transistor 305 and activation are regulated and are produced circuit 92, so that supply with regulation voltage Vreg.As a result, regulation voltage Vreg also is supplied to pierce circuit 301, and produces reference pulse from pierce circuit.

And, utilizing the sort circuit arrangement, the transistor with suitable low-voltage resistance can be used as transistor, and the electrical source consumption that produces on the circuit 92 in pressure regulation can become and is roughly zero by cutting off supply supply voltage Vc.

Though transistor 304 is switched on sever supply regulation voltage Vreg, also transistor may be linked voltage regulating line c and go up and disconnect this transistor with the sever supply charging voltage.In addition, revise the inside that the latch cicuit 202 shown in the example can be focused on central control circuit 92 first.

In addition, in above description, the on/off operation of operation of the on/off of transistor 304 and transistor 305 is carried out simultaneously, but the way of comparative optimization is to provide a delay circuit before the door of transistor 304, and at first operate transistor 305.

[5.3] the 3rd revise example

Down, will describe the 3rd with reference to figure 7 and 8 and revise example.This is revised the reference pulse that produces from pierce circuit in the example and is cut off.

At first, though revise identical in the example with second substantially around circuit arranged, the operation abortion means of being made up of transistor 304 and transistor 305 is not connected.Central control circuit 93 is connected by the signal wire d by output pierce circuit drive signal with pierce circuit 401.

The circuit structure of the pierce circuit 401 that is put into electronic watch 1 inside among Fig. 8 down, should be described.
