Technical field
The present invention relates to and can show the time with simulating with pointer, and the analog watch that digitally shows time, month and date and what day etc. when needing with LED (light emitting diode).
Background technology
Traditionally, simulate demonstration and numeral and show that both wrist-watches comprise the liquid crystal panel of less the carrying out numeral demonstration of power consumption.For such wrist-watch, for example, liquid crystal panel is arranged in the place that dial plate forms digital display window, perhaps is placed in the next door or windscreen of simulation display part as discrete topology.
Announce in Japanese laid-open patent that 2004-53342 number and 8-122468 number and Japanese laid-open utility model are announced and described these examples among the 54-172766.
Summary of the invention
The problem to be solved in the present invention
But liquid crystal panel exists that color is restricted and because its Show Color is a black, the not attractive and defective of grace inadequately of its outward appearance.In addition, liquid crystal panel also exists and is difficult to for example see the peculiar defective of demonstration at night in the dark place of light.For this reason, liquid crystal panel needs light source to throw light on, and therefore, has taked to comprise EL is used for the measure that side direction illuminates liquid crystal panel as the liquid crystal panel bias light and with LED.Simultaneously, numeral shows and simulation shows in order to carry out, and as mentioned above, must take such as the measure that forms display window in dial plate, and this has caused and comprises that design is restricted and because its display size has dwindled, is difficult to see the problem of demonstration.For example, as described in Japanese patent publication 8-122468 number, there is a kind of wrist-watch that carries out the numeral demonstration with LED.But because its simulation parts are placed on the LED next door and are in the same plane with LED, such wrist-watch can carry out less demonstration.
Therefore, numeral shows and the wrist-watch of simulation demonstration interrelates with carrying out, first purpose of the present invention is, realize that a kind of numeral shows, can not cause on the one hand to comprise its outward appearance distinctive defective of liquid crystal panel not attractive and graceful inadequately and that be difficult to see demonstration, reduce design limit on the other hand and numeral is shown bigger and easier in the dark place of light.
Second purpose of the present invention is, defines the profile of character display clearly, thereby sharp keen and clearly carry out numeral and show.
The 3rd purpose of the present invention is, all evenly clearly carries out whole numeral and shows, and can not cause the local inhomogeneous of contrast.
The 4th purpose of the present invention is to assemble each parts compactly, thereby make whole wrist-watch miniaturization.
The 5th purpose of the present invention is to realize that the bigger and easier simulation of seeing shows and numeral shows.
In addition, for example, announce as described in the 54-172766 that utilize the layout of point-like LED to need a large amount of LED show numeral and show word, this has not only caused makes more complicated problems of driving circuit, and has caused the problem that makes the cost increase as the Japanese laid-open utility model.
Therefore, the 6th purpose of the present invention is to reduce cost by quantity and the simplified driving circuit that reduces LED.
Simultaneously, the quantity by reducing LED and the configuration of simplified driving circuit reduce cost and have caused that the demonstration by LED can not expand to dial plate effectively, therefore, can not realize the problem that clear numeral shows.
Therefore, the 7th purpose of the present invention is to realize that clear numeral shows.
Simultaneously, in the past, as the light source of illumination wrist-watch, exist have the light source that is in the LED that is used for the side lighting dial plate in the sandwich portion, use light guide plate with light from LED be directed to the dial plate back side and radius as a setting light light source and with EL as the light source of bias light etc.But they any one all produced and made the size increase and make the unengaging problem of its outward appearance.
Therefore, interrelate with the wrist-watch that can carry out digital demonstration and simulation demonstration, the 8th purpose of the present invention is to obtain to be used to throw light on wrist-watch illuminating device on every side, and can not make the size increase and make outward appearance not attractive.
With can carry out numeral and show that the wrist-watch that shows with simulation interrelates, the 9th purpose of the present invention is, extended functionality, thereby further improve its added value.
Now, because its primary element size is less, has the wrist-watch of primary element as the illumination functions of its power supply is restricted aspect the power supply capacity.For this reason, when lighting source was used repeatedly, battery capacity descended rapidly, and is therefore, necessary with new battery altering used batteries.But many wrist-watches have water-proof function, and the user is difficult to do it yourself to change battery.Therefore, such wrist-watch need be changed their battery in brand shop or shop, and this brings the deuce to pay to the user.In addition, the fluorescent lifetime when not allowing to improve the brightness of LED or prolonging illumination is because such action can be quickened running down of battery.
Therefore, the tenth purpose of the present invention is to make the user illumination functions can be used for his/her core content, and need not to pay close attention to the life-span of battery and inconvenience and the relevant cost that worry is changed battery.
Simultaneously, because dial plate is furnished with for example solar cell, the wrist-watch that comprises solar cell is restricted at the shape and the design aspect of its dial plate.For such wrist-watch,, can not reach enough charge volumes according to comprising their service condition of using in outdoor use and winter.On the contrary, need be configured to and terminal can be attached on the watchcase by the wrist-watch that directly is connected the sort of type of charging with terminal.This causes the form of watchcase unique, has caused the problems such as complicacy increase that comprise its water-proof function.
So the 11 purpose of the present invention is such wrist-watch to be charged easily and reliably, and can not make design not be restricted and make water-tight structure more complicated.
Simultaneously, for example, as described in Japanese patent publication 8-122468 number, traditionally, the wrist-watch that carries out numeral demonstration and simulation demonstration is on the one hand by the oscillatory circuit in the IC of analog timer, division circuit and change-over circuit, the oscillation frequency of the output terminal of its internal oscillator circuit is converted to the motor driven pulse signal and drives step motor, thereby moving hand shows the time with simulating, on the other hand, utilize the interior division circuit and the change-over circuit of IC of LED timer, derive counting output internally in the oscillation frequency of the output terminal of oscillatory circuit, and by demoder with in the described output input light-emitting diode display, thereby on light-emitting diode display, digitally show the time.But its simulation shows that demonstration utilizes different pulse timings to drive respectively with numeral, and this can cause the time difference and make appearance poorer between them.
Therefore, interrelate with the wrist-watch that carries out numeral demonstration and simulation demonstration, the 12 purpose of the present invention is to eliminate the time difference between simulation demonstration and the numeral demonstration, thereby improve commercial value.
Traditionally, for example, as shown in figure 24, digital watch has paired appointment and four numerals of the numeral demonstration DIG1, DIG2, DIG3 and the DIG4 that form in the left and right sides proper alignment of colon 2 and the time of digital demonstration integrally, by the light source such as LED on display surface 1.In addition, as shown in figure 25, each that makes that numeral shows DIG1, DIG2, DIG3 and DIG4 keeps turn-on time " b " with constant interval " a " intermittently.In addition, numeral shows shift time " c " when DIG1, DIG2, DIG3 and DIG4 are each other, switch and connection in turn, and wholely in the time " d ", show.
But, traditionally, light source luminescent " a ", light source luminescent time " b " and light source break time " c " is at interval all fixed, and simultaneously, also fixes as the fluorescent lifetime " b " and the dutycycle of the ratio of total demonstration time " d " of numeral demonstration of each light source.In addition, dutycycle is set to bigger, so that illuminate display as much as possible.If light source is used for the bias light of liquid crystal, so, for example, the ambient illumination around illuminating or to illuminate the dial illuminance at dial plate top bright more good more.But, showing that by numeral DIG1, DIG2, DIG3 and DIG4 are used for light source under the situation of numeral demonstration, exist too bright light source and make people be difficult to read the problem that numeral shows.
Therefore, with energized and show that the timer of time interrelates, the 13 purpose of the present invention is, realizes appropriate brightness, shows thereby be convenient to read numeral.
Traditionally, digital watch is driven by battery supply.When battery supply continued to allow electric current flow through heavy duty, its magnitude of voltage descended in time by discharge curve as shown in figure 26.Then, drop to can not obtain to make the required magnitude of voltage of each element work the time at magnitude of voltage, battery just arrives the terminal point of battery life.
As shown in figure 26, the required working limit magnitude of voltage V1 of operation control CPU comprises the required working limit magnitude of voltage V2 of other element of some passive elements usually above operation.In other words, although power supply still has the magnitude of voltage that is enough to operate other element, it can not operate control CPU, thereby arrives the terminal point of battery life.For this reason, up to the present taked to comprise following measure: shorten the time that electric current flows through load; And life of product shortened that becomes short.
But these measures have caused various defectives.In addition, power source voltage fluctuates with the work of LED etc., and is reduced to below the operating voltage of timer circuit and additional function circuit, and therefore, in some cases, even power supply capacity is still higher, wrist-watch can not be worked.

Therefore, the light that passes light hole 23 inboards of shadow shield 22 can be by reflection of the inside surface of light hole 23 and scattering, thereby shine the rear surface of dial plate 24 equably, so just realized that all even in general clearly numeral shows, and can not make contrast inhomogeneous partly.
As shown in Figure 1, the dial plate 24 that has the time showing that comprises time figure and time correlation character in its surface is stacked on the shadow shield 22.By for example printing etc. coating is applied on the surface of the transparent material of being made by plastics, glass etc., forms dial plate 24.Alternately, can utilize the colored translucent material of making by plastics, glass etc. to form dial plate 24, have only when LED17 connects so that have, just allow visually to discern the light transmission that shows by the numeral that is used for the digital LED17 that shows by dial plate 24.Best, light transmission is 1-70%.The periphery of dial plate 24 is abutted against on the sandwich portion of watchcase 10, then, the gained composite entity of dial plate and shadow shield is placed in the watchcase 10.
In the example shown in Fig. 4 (A) and 4 (B), shadow shield 22 is to form like this, each light hole 23 is uniformly from its back side (that is, that side approaching with circuit board 16) to its front (or dial plate 24 sides) width, but has narrower width at its front openings place.But shown in Fig. 5 (A) and 5 (B), shadow shield 22 also can form like this, and width is narrowed down from the back side to the front gradually.When forming this layout, the light that passes each light hole 23 inboard can be reflected and scattering by the inside surface of light hole 23, and light hole 23 is narrowed down gradually towards dial plate 24, thereby can guide light collected light simultaneously.The same with the situation shown in Fig. 4 (A) and 4 (B), by astigmatic coating 50 is applied on the inside surface of each light hole 23 that forms, form the shadow shield 22 in (A) in having the tabular resin component element 22A of high light shielding ability.By shading coating 51 is applied on the front surface of the tabular resin component element 22B with high light reflectivity rate, form the shadow shield 22 in (B).
Shown in Fig. 6 (A) and 6 (B), shadow shield 22 can form like this, makes the size of each light hole 23 vertically become big gradually from the back side towards the front along it.When forming this layout, can be from the light that is installed in each LED17 on the circuit board 16 by reflection of the inside surface of light hole 23 and scattering, and can make the size of light hole 23 longitudinally elongated gradually, thereby can easily guide reflected light into outside towards dial plate 24.The same with above-mentioned example, by astigmatic coating 50 is applied on the inside surface of each light hole 23 that forms, form the shadow shield 22 in (A) in having the tabular resin component element 22A of high light shielding ability.By shading coating 51 is applied on the front surface of the tabular resin component element 22B with high light reflectivity rate, form the shadow shield 22 in (B).
Shown in Fig. 7 (A) and 7 (B), shadow shield 22 can form like this, and the semi-transparent resin 53 that will be used for scattered beam is assemblied in the front openings of each light hole 23 that for example is arranged to have narrower width.The assembling that is used for the semi-transparent resin 53 of scattered beam can be before shadow shield 22 be stacked on the circuit board 16, or is stacked at shadow shield 22 and carries out after subsequently LED17 being inserted in the light hole 23 on the circuit board 16.Replace assembling, for example can when forming shadow shield, use dual-color forming, thereby from the resin of the color of scattered light often, form and light hole 23 corresponding parts.When forming this layout, can be from the light of LED17 by resin scattering that can scattered light, therefore, the rear surface of illuminated dial 24 equably.Therefore, can present all even clearly numeral shows.The same with above-mentioned example, by astigmatic coating 50 is applied on the inside surface of each light hole 23 that forms, form the shadow shield 22 in (A) in having the tabular resin component element 22A of high light shielding ability.By shading coating 51 is applied on the front surface of the tabular resin component element 22B with high light reflectivity rate, form the shadow shield 22 in (B).
Though in above-mentioned example, shadow shield 22 is formed by single member,, shown in Fig. 8 (A) and 8 (B), also can form shadow shield by two tabular components are put together.For resin component element 22A or the resin component element 22B as single tabular component, the hole 23a that is used to form each light hole 23 prevents the light transverse leakage from LED17.About the thin hardware 22C as another tabular component, the hole 23b that is used to form each light hole 23 will be configured as arc from the light of LED17.On the inside surface of each light hole 23a by astigmatic coating 50 being applied to tabular resin component element 22A, form the shadow shield 22 in (A) with high light shielding ability.Form shadow shield 22 in (B) by tabular resin component element 22B with high light reflectivity rate.
Now, substituted metal member 22C shown in Fig. 9 (A) and 9 (B), can form the layout that comprises the steps: shading coating 54 is printed on the dial plate 24; And the hole 23b that in shading coating 54, is provided for forming light hole 23.On the inside surface of hole 23a by astigmatic coating 50 being applied to the formation light hole 23 that tabular resin component element 22A with high light shielding ability had, form the shadow shield 22 among Fig. 9 (A).Form shadow shield 22 in (B) by the tabular resin component element 22B that has the high light reflectivity rate and have a hole 23a that forms light hole 23.A hole 23a who forms light hole 23 prevents the light transverse leakage from LED17, and that another hole 23b will be configured as from the light of LED17 will be arc.
Now, shown in Figure 10 (A) and 10 (B), be furnished with at it vertically during the LED17 of the customized lenses of expansion light when use, light expand light hole 23 in, so that the rear surface of uniform irradiation dial plate 24, thereby can present all even clearly digital demonstration.On the inside surface of the light hole 23 by astigmatic coating 50 being applied to tabular resin component element 22A, form the shadow shield 22 in (A) with high light shielding ability.By shading coating 51 is applied on the surface of the tabular resin component element 22B with high light reflectivity rate, form the shadow shield 22 in (B).
Simultaneously, dial plate 24 stands the astigmatism processing with light hole 23 corresponding positions at least.For example, shown in Figure 11 (A), dial plate 24 forms as follows: time showing part 41 is provided on the front surface of transparent resin plate 40; On the rear surface, carry out coloured printing 42, thus pigmentary resin plate 40; Then, carry out astigmatism white printing 43 in its outside.Certainly, the printing that is used for astigmatism is not limited to white ink, if can scattering from the light of LED17.
In addition, shown in Figure 11 (B), the layout that can comprise the steps: utilize aforementioned colored materials to make resin plate 40; Time showing part 41 is provided on the front surface of resin plate 40; What then, be formed for scattered light on the rear surface has concavo-convex 44 of a few to tens of micron thickness t.And, shown in Figure 11 (C), the layout that can comprise the steps: on the front surface of the resin plate 40 that utilizes aforementioned colored materials to form, provide time showing part 41; And the astigmatism printing 45 that on the rear surface, is used for scattered light.Astigmatism printing 43,45 and concavo-convex 44 may not be provided on the whole surface of resin plate 40, they can be provided at least and light hole 23 corresponding positions.
For example, as shown in figure 12, at the rear portion of the dial plate 24 relative with light hole 23, with the immediate position of LED17 on carry out can scattered light printing 45.When forming this layouts because printing 45 scatterings are from the light of LED17, from the light of LED17 equably radiation at dial plate 24 rear portions relative with light hole 23, and no matter dial plate near or away from LED17.
According to this mode, as shown in Figure 1, be equipped with shadow shield 22 at the back side of dial plate 24; Circuit board 16 is placed on the back side of shadow shield 22; And provide parts 13 at the back side of circuit board 16.Then, the LED17 that is used for the numeral demonstration on the circuit board 16 is placed on the back side of dial plate 24.
The center pit (in Fig. 3 with symbol " j " expression) that pen travel axle 15 passes shadow shield 22 extends to the center pit (among Fig. 1 with symbol " k " expression) of dial plate 24 from the center pit " h " of circuit board 16, and its front end is exposed to the front of dial plate 24.Hour hands 25, minute hand 26 and second hand 27 are attached on the front end.
Be equipped with charging circuit in parts 13 and bonnet 12 more approaching sides, and button secondary cell 30 is placed to covered on parts 13.And, secondary coil 32 annularly on line tube 31, is mounted to the periphery that surrounds secondary cell 30 then.In other words, in example as shown in the figure, secondary cell 30 and secondary coil 32 are placed on the same plane.
In addition, the led drive circuit 33 of driving LED 17 has been installed at the back side of the circuit board 16 in watchcase 10 on the plane identical with the plane at parts 13 places.When as shown in figure 13, when led drive circuit 33 is directly installed on the back side of circuit board 16, can save the space.Led drive circuit 33 comprises the LED driver module that can connect all LED17 according to peripheral operation.In addition, led drive circuit 33 also comprises and can start additional clocking capability according to peripheral operation, for example, and the LED driver module of stopwatch, alarm and timer.
On the other hand, in wrist-watch as shown in the figure, the axle nuclear 36 that the outer end has button 35 is passed in the casing 10 insertion parts 10.Equally, the operating axis that unshowned in the drawings outer end has shift knob is passed in the casing 10 insertion parts 10.In Figure 13, use the label identical to identify with the label of the part that is used for Fig. 1 with those the corresponding parts among Fig. 1.
For analog watch as shown in the figure, generally disconnect and be used for the LED17 that numeral shows.Secondary cell 30 drives parts 13 rotating pointer 25-27, thereby allows pointer 25-27 be used for time showing on the dial plate 24.Therefore, indicate the demonstration time by pointer 25-27 with simulating.If needed, can suitably connect LED17, by 23 guiding of the light hole in the shadow shield 22, and make it pass dial plate 24, thereby digitally show time, month and date and what day etc. from the light of LED17 according to peripheral operation.For correction time, can handle button 35 so that make parts 13 motions by axle nuclear 36, thus rotating pointer 25-27.
As mentioned above,, can reduce design limit, so that guarantee the diversity of design by the following: LED17 is arranged to generally disconnects them for carrying out the wrist-watch that numeral shows and simulation shows; Utilize pointer 25-27 to show the time with simulating; Hiding LED by dial plate is not seen it; And need not in dial plate to form digital display window.In addition, if necessary, connect LED, then, digitally show time, month and date and what day etc., like this,, also can realize bright the demonstration with shades of colour even in the dark place of light by dial plate 24.Consequently, on the one hand, can eliminate such as the distinctive defective of liquid crystal panel that shows that outward appearance is not attractive and be difficult to see in the dark place of light demonstration; On the other hand, can present numeral by the visibility that improves commodiously on whole dial plate 24 shows.
And, the colon 19 of the LED17 formation that is clipped in the middle by the center pit " h " with circuit board 16 is provided, and with colon 19 be clipped in the middle ground in pairs distribute digital show DIG11, DIG12, DIG13 and DIG14, numeral show DIG11, DIG12, DIG13 and DIG14 each have the one group of LED17 that puts into expression numerical character " 8 ".Consequently, can use the almost the same circuit board 16 of size with dial plate 24.Therefore, when LED17 being placed on the entire circuit plate 16, can use the whole plate face of dial plate 24 effectively, thereby make numeral show bigger and easier seeing.
In example as shown in the figure, the light hole 23 that passes shadow shield 22 owing to the light from LED17 is radiated on the rear surface of dial plate 24, and pass dial plate 24, and can clearly limit the profile of character display by light hole 23, thus can be sharply and clearly carry out numeral and show.In addition, from the light of LED17 when passing the inside of light hole 23, by the inside surface of the light hole 23 of shadow shield 22 reflection and scattering, thus can be equably and clearly present whole numeral and show, and can not cause partly that in light hole 23 contrast is inhomogeneous.
Simultaneously, in example as shown in the figure,, generally can dwindle the size of wrist-watch owing to assembling the parts that comprise dial plate 24, shadow shield 22, circuit board 16, simulation parts 13 and led drive circuit 33 compactly and placing it in the watchcase 10.And,, can provide numeral to show in the center of dial plate 24 owing in analog watch as shown in the figure, the LED17 that constitutes colon can be equipped to the center pit that will pass therethrough the circuit board 16 of pen travel axle 15 and be clipped in the middle.Therefore, can present numeral commodiously on whole dial plate shows and the simulation demonstration.Therefore, can present the bigger and easier simulation of seeing shows and the numeral demonstration.
In this case, be equipped with LED17 correspondingly, therefore, the quantity of LED can have been minimized with light hole 23.Consequently, configuration that can simplified driving circuit, and can reduce cost.In addition owing to handle dial plate 24 being carried out astigmatism at least with light hole 23 corresponding positions, through the part scattering of astigmatism processing from the light of LED and make light pass light hole 23 equably.Therefore, even the quantity of LED17 has reduced, also can carrying out clearly, numeral shows.
In addition, because in example as shown in the figure, led drive circuit 33 comprises the LED driver module that can connect all LED17 according to peripheral operation, can make led drive circuit 33 work by peripheral operation, so that for example be difficult to see under the situation of keyhole, connect all LED in the place that needs illuminate in the dark place of light.In addition, secondary cell 30 can be used as power supply, so that outside by windscreen illumination, and the LED17 of demonstration time etc. itself can be used for illumination.Therefore, need not to cause the wrist-watch size to increase and around the fill light light source of its degraded appearance just can illuminate.
And, in example as shown in the figure, led drive circuit 33 comprises and can start additional clocking capability according to the peripheral operation of unshowned shift knob (for example, stopwatch, alarm and timer) the LED driver module, like this, can on function, expand and carry out the wrist-watch that numeral shows and simulation shows, thereby improve its added value.
When operating in not shown shift knob once more, cut off LED17 from the external world.Certainly, all the other lighting hours can be arranged to when after switching manipulation, having passed through certain time span, cut off LED17 automatically.In addition, can be equipped with a plurality of shift knobs and replace a shift knob.In this case, operation button switch can switch demonstration or connection/cut-out LED.
Simultaneously,, when the battery capacity of secondary cell 30 has reduced by using, wrist-watch is placed on the not shown charger by wrist-watch as shown in the figure, thus by electromagnetic induction to battery charge.Specifically, flow through primary coil, make the primary coil of timer generate alternating magnetic field by the AC electric current that allows AC (interchange) electric wire supply.Then, this alternating magnetic field is used to make the secondary coil 32 of wrist-watch as shown in the figure to generate alternating current.This alternating current charges to secondary cell 30 by the rectification circuit rectification and as direct current.
Because secondary cell 30 is used as power supply, even the frequent use of LED17 has exhausted battery, also only need be just passable to battery charge, do not need to change battery.Therefore, need not to pay close attention to the life-span of battery and inconvenience and the relevant cost that worry replacing battery brings, can fully use illumination functions.Consequently, can eliminate use with liquid crystal panel mutually the LED17 of specific consumption greater amount electric power carry out numeral and show the defective brought.
In example as shown in the figure, charge by the secondary cell 30 of electromagnetic induction to charging circuit.But secondary cell 30 can be a solar cell.Otherwise, can be by directly being connected to come directly to secondary cell charge with power end.When secondary cell 30 being charged, can realize simple and reliable charging, and can not make design not be restricted and make water-tight structure more complicated when being equipped with secondary coil 32 so that by the electromagnetic induction realization.
Figure 14 provides the calcspar of explanation at the time adjustment of analog watch shown in Figure 1.
Figure 15 provides the sequential chart during simulated time is proofreaied and correct.
As shown in the figure, when during simulated time is proofreaied and correct, extracting button 35, start parts so that the replacement analog pulse by axle nuclear 36.Then, rotation button 35 comes rotating pointer 25-27 by axle nuclear 36, thereby pointer is adjusted to required time.After this, in suitable timing, for example, depress button 35 when the time is set waiting, thereby generate time clock and therefore drive the simulation part by time signal.That is to say that moving and depressing button 35 of simulated pointer begins simultaneously.
In the time clock input digit counter that will when depressing button 35, generate in addition.Then, counter and simulated pointer begin to move synchronously upwards counting, and drive numerical portion so that make numeral show that pulse timing and simulated pointer move the pulse timing coupling.
Figure 16 provides the sequential chart during proofread and correct digit time.
Even when operating in not shown shift knob in proofreading and correct digit time, move and the switching manipulation of simulated pointer irrespectively continue.But, in case accept the rupturing operation of switch, make the upwards counting that moves synchronously of counter and simulated pointer, and drive numerical portion, thereby make numeral show that pulse timing and simulated pointer move the pulse timing coupling.
Therefore, with both show that control circuit control simulated pointer moves pulse timing and numeral shows pulse timing, makes their phase mutually synchronization in the example as shown in the figure that the wrist-watch of time interrelates with numeral and simulation.Therefore, eliminated the time difference between simulation demonstration and the numeral demonstration, thereby improved commercial value.Especially, with the example as shown in the figure that comes numeral and simulation ground to show that the wrist-watch of time interrelates according to the simulation mode of priority in, can form such layout, make when the digit time of proofreading and correct as additional function, not carry out correction as preferential simulated time.
Figure 17 is given in the calcspar under the situation that demonstration is carried out rounding off in 30 seconds to numeral in the simulated time correction.
As shown in the figure, when depressing button 35, start parts with the replacement analog pulse by axle nuclear 36, and startup turns back to zero circuit.Then, when the second of digital counter, counting was lower than 30, digital counter is counted downwards, and made the second position of counter turn back to zero.On the contrary, when the second counting of digital counter more than or equal to 30 the time, make upwards counting of digital counter, and make the second position of counter turn back to zero.In addition, when depressing button 35 in the same manner, digital counter and simulated pointer begin to move synchronously upwards counting, and the driving numerical portion makes numeral show that pulse timing and simulated pointer move the pulse timing coupling.When numeral being shown turn back to zero, can eliminate difficulty with second correction time.
Figure 18 provides the calcspar of above-mentioned wrist-watch.
Wrist-watch as shown in the figure comprises the light source dutycycle adjustment control circuit 60 that can adjust dutycycle.Dutycycle is the ratio that LED17 keeps the fluorescent lifetime of connecting and total demonstration time of carrying out the numeral demonstration.Control circuit 60 changes the dutycycle of each LED17 according to various conditions, has appropriate brightness thereby numeral is shown.
For example, the message segment that will obtain from analog-and digital-clocking capability is kept in the microcomputer 61 as time data 62.Time data 62 input light source dutycycles are adjusted in the control circuit 60.Adjust the dutycycle of each LED17 according to time data 62, then, driving light source driving circuit 63 shows thereby force display part 64 to carry out numeral.
Figure 19 shows the driving sequential of numeral demonstration DIG11, DIG12, DIG13 and DIG14 in the display part 64.
As shown in the figure, the same with the past, numeral shows that DIG11, DIG12, DIG13 and DIG14 are respectively with constant interval " A " turn-on time " B " intermittently.In addition, numeral shows DIG11, DIG12, DIG13 and DIG14 traveling time " X " each other, switch and connection in turn.Therefore, display part 64 is whole showed in the time " D ".
In wrist-watch as shown in the figure, control circuit 60 can be adjusted dutycycle by for example changing its light source break time " X ".It is daytime or evening that time data 62 is used for judging.Shorten light source break time " X " bright around daytime, thereby it is brighter that numeral is shown, and prolong light source break time " X " dark around evening, thereby it is darker that numeral is shown.Therefore, make numeral show easier seeing.Nature, when light source break time " X " was zero (0), dutycycle was 100%, therefore, it is the brightest that numeral is shown.
In addition, as shown in figure 20, for example, wrist-watch can have the photosensitive device 65 on the circuit board 16 that is installed in dial plate 24 back sides.As shown in figure 18, will be from preserving in the output signal input microcomputer 61 of photosensitive device 65 and as photosensitive device data 66.Photosensitive device data 66 input light source dutycycles are adjusted in the control circuit 60.Adjust the dutycycle of each LED17 according to photosensitive device data 66, then, driving light source driving circuit 63 shows so that force display part 64 to carry out numeral.
Then, built in light sensing device 65 is used for the sensing room environment, and judges brightness in the room according to photosensitive device data 66.When the room is bright, shorten light source break time " X ", thereby it is brighter that numeral is shown, and when the room is dim, prolong light source break time " X ", thereby it is darker that numeral is shown, therefore, makes numeral show easier seeing.
And, as shown in figure 18, with in the light transmission of the dial plate 18 input microcomputer 61 and be stored in wherein as dial plate light transmission data 67.Dial plate light transmission data 67 input light source dutycycles are adjusted in the control circuit 60.Adjust the dutycycle of each LED17 according to dial plate light transmission data 67, then, driving light source driving circuit 63 shows so that force display part 64 to carry out numeral.
Then, judge the light transmission of the dial plate 24 of use according to dial plate light transmission data 67.When using the lower dial plate of light transmission, shorten light source break time " X ", thereby make LED17 brighter.When using the higher dial plate of light transmission, prolong light source break time " X ", thereby it is darker that numeral is shown, therefore, make numeral show easier seeing.
Further, can detect the voltage of secondary cell 30 by being built in voltage detector component in the circuit.With the store voltages that detects in microcomputer 61 as detection voltage data 68.To detect voltage data 68 input light source dutycycles adjusts in the control circuit 60.Adjust the dutycycle of each LED17 according to detecting voltage data 68, then, driving light source driving circuit 63 shows so that force display part 64 to carry out numeral.
Then, when the cell voltage that detects is low, that is, when battery exhausts, shorten light source break time " X ", thereby it is brighter that numeral is shown.When the cell voltage that detects is high, that is, when battery does not also exhaust, prolong light source break time " X ", thereby it is darker that numeral is shown, therefore, make numeral show easier seeing, reduced power consumption simultaneously.
Though described the situation that is shown the 4-bit digital demonstration that DIG11, DIG12, DIG13, DIG14 form by numeral at above-mentioned example, the present invention is not limited to 4 bit digital.Can determine dutycycle by the condition that combination comprises time data, photosensitive device data, dial plate light transmission data and detects voltage data, thereby make the numeral demonstration have suitable brightness.
