Secondly the moment corrective action with regard to this electric wave correcting clock is illustrated.
The 12nd figure represents to carve for the moment the corrective action example.In this, the 1st No. 5 gear 22,23, No. 3 gears 33 of second hand wheel, minute wheel 34, hour wheel 36 are by rotating driving by the driving of the stepping of the 1st step motor 21 of control part control and the 2nd step motor 31 respectively.At this moment, the 1st No. 5 gear 22 are by the stepper drive of the 1st step motor 21, with 1 mode drive controlling of 15 steps rotation, and the result, second hand wheel 23 is with the rotation of 60 steps once.On the other hand, No. 3 gears 33 are by the stepper drive of the 2nd step motor 31, with 1 mode drive controlling of 60 steps rotation, and the result, second hand wheel 34 is with 360 step rotations 1 time, and 36 of hour wheels are with the rotation of 4320 steps once.
Shown in the 12nd figure, at first resetting (reset) or during power connection, the conducting starting switch, light-emitting component 42, i.e. light-emittingdiode starts and sends and detect light (S1) with the regulation output frequency.Now, the 1st step motor 21 judge that having denys to come self-emission device 44, i.e. the output of photoelectric crystal with pulsed drive (S2).
In this, under the output situation of not having from photoelectric crystal, add when being used for carrying out the umber of pulse of stepper drive, judge the output have not from photoelectric crystal, even umber of pulse reach 9 also do not have from photoelectric crystal output the time, the 2nd step motor 31 drove for 1 step (pulse) (S5), stepper drive (S2) the 1st step motor 21 once again after this, and rotation drives second hand wheel 23.
On the other hand, when the output that photoelectric crystal is arranged, second hand wheel 23 is advanced (S6) fast, carry out comparing (S7), when the output pattern of gained output pattern and memory does not match, second hand wheel 23 is advanced fast with the output pattern of remembering in advance in control part.On the other hand, when the output pattern coupling of gained output pattern and memory, in this moment (not obtaining from the output of photoelectric crystal and Yu Ciyi step when obtaining the output of photoelectric crystal) in the 5th step, stop second hand wheel 23 (stopping the 1st step motor 21), drive second hand wheel 23 to return-to-zero position and stop (S8).At this moment, second hand is modified to regulation constantly, for example the position of timing points (0 second).
Then, to stipulate only pulsed drive the 2nd step motor 31 of output frequency, make minute wheel 34 quicker advancing (SP).And carry out from the output pattern of photoelectric crystal and the comparison (S10) that is stored in the output pattern of control part in advance, when gained output pattern does not match with the pattern of storing, minute wheel 34 is advanced fast.On the other hand, when gained output pattern mates with store output pattern, stop the 2nd step motor 31, stop the driving (S11) of minute wheel 34 and hour wheel 36 this moment.
In this, utilize above-mentioned output pattern and moment of being done of pattern comparison of storage in advance to revise and undertaken by mating with any one of three kinds of patterns.That is shown in the 13rd figure (a), the output pattern that utilizes minute wheel 34 photoelectric crystal of doing disconnects fabric width as the light shielding part effect, forms two patterns of B portion and the mutual appearance of a wide cut A portion in a narrow margin.Again, shown in the 13rd figure (b), utilize the output pattern of hour wheel 36 photoelectric crystal of doing to form the light shielding part effect and disconnect fabric width, form three kinds of D portions, E portion, C portion every predetermined distance and the mutual pattern that occurs.Shown in the 13rd figure (c), synthetic the two output pattern forms the pattern of pattern, E portion, B portion and the combination of A portion of D portion, B portion and the combination of A portion and three kinds of patterns that occur every predetermined distance such as pattern of C portion, B portion and the combination of A portion.And, shown in the 13rd figure in the pattern pattern of conducting part owing to actually have light shielding part to form the part that disconnects, so become not have the dentation pattern by No. 3 gears 33.
Therefore, if preestablish the moment of the pattern that combination constitutes of confirming D portion, B portion and A portion, for example 4: 00, the moment of confirming the pattern that combination constitutes of E portion, B portion and A portion for example is 8: 00, and the pattern that combination constitutes of affirmation C portion, B portion and A portion for example is 12: 00, can be in detecting these patterns any the time, stop the 2nd step motor 31, by this, can be with minute wheel 34 and hour wheel 36, that is the moment of minute hand and hour hands is modified to regulation constantly.
After stopping above-mentioned the 2nd step motor 31, cut off the output of light-emittingdiode, stop luminous (S12), the finish time corrective action.
According to the electric wave correcting clock that carries out above-mentioned action, owing to use circular-arc through hole, that is slotted hole, in minute wheel 34 and hour wheel 36, as the through hole that passes through for detection light, so photodetector 40 conducting expanded range can shorten the position probing time, as a result, can shorten and carry out the time that second hand is revised constantly.Multiple owing to be provided with 3 kinds of light shielding part C, D, E in hour wheel 36, event can detect any one of 3 positions, carrying out the moment revises, again, than person before, it is about 1/3 that the slowest hour wheel of rotational speed 36 is only rotated, and carries out position probing, can shorten the time that moment of carrying out minute hand and hour hands revises by this.
Secondly other moment corrective actions with regard to this electric wave correcting clock are illustrated.
The 14th figure shows another example of corrective action constantly.In this, the 1st No. 5 gear 22,23, No. 3 gears 33 of second hand wheel, minute wheel 34, hour wheel 36 are the same with aforementioned driving method, and the 1st step motor of controlling by each control part 21 and the stepper drive rotation of the 2nd step motor 31 drive.At this moment, the 1st No. 5 gear 22 are by the stepper drive of the 1st step motor 21, with 1 mode drive controlling of 15 steps rotation, and the result, second hand wheel 26 is with 60 step rotations 1 time.On the other hand, No. 3 gears 33 are by the stepper drive of the 2nd step motor 31, with 1 mode drive controlling of 60 steps rotation, and the result, minute wheel 34 is with 360 step rotations 1 time, and hour wheel 36 is with 4320 step rotations 1 time.Under this situation, the 1st No. 5 gears 22 detect light by 21 every 5 steps of driving of the 1st step motor by 1 time, and again, No. 3 gear 33 detects light by 31 every 6 steps of driving of the 2nd step motor by 1 time.
Shown in the 14th figure, at first, reset (reset) or during energized, the conducting starting switch, light-emitting component 42, that is light-emittingdiode starts and sends and detect light (S1).Now, the 1st step motor 21 and the 2nd step motor 31 are simultaneously with identical output frequency pulsed drive, and rotation driving second hand wheel 23 and minute wheel 34 (and hour wheel 36) are (S2).Secondly, judging has not from photo detector 44, that is the output of photoelectric crystal (S3).
In this, under the output situation of not having from photoelectric crystal, pulsed drive the 1st step motor 21 and the 2nd step motor 31 rotate driving second hand defeated 23 and minute wheel 34 (and hour wheel 36) once again.On the other hand, under the output situation that has from photoelectric crystal, in case stop second hand wheel 23 and minute wheel 34 (hour wheel 36) (S4), promptly after this, fast moving second hand wheel 23 (S5), carry out comparing (S6) with the output pattern that is stored in control part in advance, when gained output pattern did not match with store output pattern, the fast moving second hand wheel 23 once again.On the other hand, when gained output pattern mates with store output pattern, stop second hand wheel 23 (stopping the 1st step motor 21), drive second hand wheel 23 to the position of making zero and stop (S7) this moment.At this moment, second hand is modified to regulation constantly, for example timing points position (0 second).
Then, only pulsed drive the 2nd step motor 31, more fast moving minute wheel 34 (S8).And, carry out from the output pattern of photoelectric crystal with remember in the comparison (S9) of the output pattern of control part in advance, store when exporting pattern and not matching in gained output pattern and institute, the fast moving minute wheel 34 once again.On the other hand, when gained output pattern mates with the output pattern of being stored, stop the 2nd step motor 31, stop the driving of minute wheel 34 and hour wheel 36 this moment.
In this, it is identical with aforementioned circumstances to utilize moment of being done of pattern comparison of above-mentioned output pattern and storage in advance to revise, by with three kinds of patterns in any mates and carries out.That is, shown in the 13rd figure (a), utilize the output pattern of minute wheel 34 photoelectric crystal of doing to form the fabric width that the light shielding part effect disconnects, form two patterns of B portion and the mutual appearance of a wide cut A portion in a narrow margin.Again, shown in the 13rd figure (b), utilize the output pattern of hour wheel 36 photoelectric crystal of doing to form the light shielding part effect and disconnect fabric width, form 3 kinds of D portions, E portion, C portion every predetermined distance and the mutual pattern that occurs.Shown in the 13rd figure (c), synthetic both output pattern forms the pattern of pattern, E portion, B portion and the combination of A portion of D portion, B portion and the combination of A portion and 3 kinds of patterns that occur every predetermined distance such as pattern of C portion, B portion and the combination of A portion.
Therefore, if preestablishing the moment of the pattern of confirming that D portion, B portion and the combination of A portion are constituted for example is 4: 00, the moment of confirming E portion, B portion and A portion pattern that combination constitutes for example is 8: 00, the moment of confirming C portion, B portion and A portion pattern that combination constitutes for example is 12: 00, can be in detecting these patterns any one the time, stop the 2nd step motor 31, by this can be with minute wheel 34 and hour wheel 36, that is the moment of minute hand and hour hands is modified to regulation constantly.
After above-mentioned the 2nd step motor 31 stops, cutting off the output of light-emittingdiode, stop luminous (S11), the finish time corrective action.

Therefore, in external factor based on assembling back bump etc., relative rotation takes place between the 1st step motor 21 and the 2nd step motor 31, during both rotatable phase displacement, even rotation drives the 1st step motor 21 and the 2nd step motor 31 simultaneously, also certainly exist the consistent position of phase place (light detects the output conduction position with sensor).
For example, when No. 3 gear 33 skews, the 1st No. 5 gear 22 are every 5 umber of pulses of the 1st step motor 21, that is whenever 0,5,10,15,20,25,30 ... pulse is passed through detection light, on the other hand, No. 3 gears 33 when each skew 1 umber of pulse whenever 1,7,13,19,25,31 ... pulse is passed through detection light, and when skew 2 umber of pulses, whenever 2,8,14,20,26,32 ... pulse is passed through detection light, when skew 3 umber of pulses, whenever 3,9,15,21,27,33 ... pulse is passed through detection light, when skew 4 umber of pulses, whenever 4,10,16,26 ... pulse is passed through detection light.At this moment, in skew during 1 umber of pulse in 25 pulses place, when skew 2 umber of pulses and in 20 pulses place, when skew 3 umber of pulses in 15 pulses place, when skew 4 umber of pulses in both phase place unanimities of 5 pulses place.
On the other hand, when 22 skews of the 1st No. 5 gears, No. 3 gears 33 are every 6 umber of pulses of the 2nd step motor 31, that is whenever 0,6,12,18,24,30 ... pulse is passed through detection light, on the other hand, the 1st No. 5 gears 22 are when skew 1 arteries and veins is counted, whenever 1,6,11,16,21,26 ... pulse is passed through detection light, again, when skew 2 umber of pulses, whenever 2,7,12,17,22,27 ... pulse is passed through detection light, when skew 3 umber of pulses, whenever 3,8,13,18,23,28 ... pulse is passed through detection light, when skew 4 umber of pulses, whenever 4,9,14,19,24,29 ... pulse is passed through detection light, when skew 5 umber of pulses, whenever 5,10,15,20,25,30 ... pulse is passed through detection light.At this moment, in skew during 1 umber of pulse in 6 pulses place, when skew 2 umber of pulses in 12 pulses place, when skew 3 umber of pulses in 18 pulses place, when skew 4 umber of pulses then in 24 pulses place, when skew 5 umber of pulses in 30 pulses place, both phase place unanimities.
That is, carry out the position consistency of second hand and the position alignment of minute hand and hour hands owing to can drive two motor 21,31 simultaneously, revising the required time constantly so can shorten all.
