Then, the movement in 2 months in non-leap year is illustrated.

In the case where 2 months of non-leap year, since last day is 28, pass through date finger driving wheel 40 and solar month of 30 days date finger driving wheel 25 Both sides feed to carry out the date at the end of month.Specifically, at 28 days of 2 months of non-leap year, make date in solar month of 30 days feeding claw 35 and the end of month The claw 55 of pawl 53 engages and date wheel 50 is made to rotate 3 steps, and then make to be set to date finger driving wheel 40 changes day pawl 42 and the date gear teeth Portion 51 engages and date wheel 50 is made to rotate 1 step.

Figure 12 is the figure being illustrated to the movement of the calendar mechanism of embodiment, and is show 2 months of non-leap year 28 The top view of when day, a part of date feed mechanism structure.

As shown in figure 12, month cam 27 formation are as follows: in 2 months, the top of the 2nd protrusion 27a and be in correspond to from 29 days Claw 55 to the end of month pawl 53 of the position during 30 days is opposite.In addition, year cam 28 is formed as, in 2 months of non-leap year, The top of 3rd protrusion 28a and the claw 55 for being in the end of month pawl 53 corresponding to position on the 28th are opposite.Date in solar month of 30 days as a result, Feeding claw 35 was configured by year cam 28 in outermost position on 28th.In addition, when date wheel 50 be in correspond to from 28 days to When position during 30 days, the claw 55 of the end of month pawl 53 is configured in the rotation of date in the solar month of 30 days feed bar 30 in outermost position The inside of transition mark.Here, the top of the 1st protrusion 27b~27e is compared at the top of the 2nd protrusion 27a in the circumferential direction around the 1st axis C1 Size it is big.In addition, the top of the 3rd protrusion 28a is connected with the top of the 2nd protrusion 27a from the end on observation of the 1st axis C1.Cause This, long time the case where date in solar month of 30 days feeding claw 35 was with 2 months than the leap year configures in outermost position.Therefore, the date in solar month of 30 days into To pawl 35 after abutting and engaging with the end of month pawl 53 on 28th by the rotation of solar month of 30 days date finger driving wheel 25, with the process at moment Press the claw 55 of the end of month pawl 53, the 3rd big angle of the 2nd angle for keeping 50 speed ratio of date wheel above-mentioned.

Also, it is pressed in the end of month pawl 53 by date in solar month of 30 days feeding claw 35 and makes the date synchronously rotated with the end of month pawl 53 Wheel 50 is when rotating 3 angle along the direction CW, the terminal part 57 of date locating rod 56 and the releasing of the engaging of date wheel teeth portion 51 Engage again and is repeated 3 times.Date wheel 50 and day cam 61 are as a result, with defined angle spacing 3 steps of rotation.Day needle 7 from 28 as a result, The amount for day being switched to 31 and taking the needle 3 days.

By above-mentioned movement, in the case where 2 months of non-leap year, date wheel 50 and day cam 61 are with defined angle spacing In one day 4 step of rotation.In other words, by the action, day needle 7 makes 29,30 and 31 days fastly from 28 days and then is switched to 1 Day.

Also, day cam 61 rotates 1 step in last day, i.e. 31 day in the solar month, in the moon in addition to 2 months in the small middle of the month 2 steps of rotation on the 30th, in 2 months 3 steps of rotation on the 29th in leap year, in 2 months 4 steps of rotation on the 28th in non-leap year, pointer release link as a result, 70 follower 71 passes through the most external 63 of day cam 61.In addition, after follower 71 is by most external 63, pointer release link 70 It is moved to initial position from final position moment by the active force of reseting wheel 78 (referring to the double dot dash line in Fig. 7).Refer to as a result, The follower 71 of needle release link 70 is relatively moved to the penetralia 64 of day cam 61.

At this point, in the case where the last day in the solar month, day, pinwheel 67 was with the slave final position of pointer release link 70 to first The movement of beginning position is correspondingly rotated along the direction CCW moment.Be installed on as a result, day pinwheel 67 day needle 7 from indicating last The position moment of its " 31 " is moved to the position of instruction first day " 1 ".

In addition, in the case where 30 days of the moon in addition to 2 months in the small middle of the month, day pinwheel 67 with date wheel 50 and day cam The 61 1 step rotation based on the end of month pawl 53 correspondingly makes pointer release link 70 reach final position.At this point, day pinwheel 67 is along CW Direction rotates 1 step.In addition, the day needle 7 for being installed on day pinwheel 67 is moved to from the position of the last day i.e. " 30 " in instruction solar month of 30 days Indicate the position of " 31 ".

Then, with solar month the case where, is identical, and day, pinwheel 67 was with the slave final position of pointer release link 70 to initial position It is mobile correspondingly to be rotated along the direction CCW moment.Be installed on as a result, day pinwheel 67 day needle 7 from instruction last day " 31 " Position moment is moved to the position of instruction first day " 1 ".

In addition, in the case where 29 days of 2 months of the leap year, day, pinwheel 67 was with date wheel 50 and day cam 61 based on the end of month The 2 steps rotation of pawl 53 correspondingly makes pointer release link 70 reach final position.At this point, day pinwheel 67 rotates 2 steps along the direction CW. In addition, the day needle 7 for being installed on day pinwheel 67 from the position of 2 months last days i.e. " 29 " in instruction leap year is moved to instruction " 31 " Position.

In addition, in the case where 28 days of 2 months of non-leap year, day, pinwheel 67 was with date wheel 50 and day cam 61 based on the end of month The 3 steps rotation of pawl 53 correspondingly makes pointer release link 70 reach final position.At this point, day pinwheel 67 rotates 3 steps along the direction CW. In addition, the day needle 7 for being installed on day pinwheel 67 from the position of 2 months last days i.e. " 28 " in instruction non-leap year is moved to instruction " 31 " Position.

In this way, calendar mechanism 10 according to the present embodiment, in the last day in the solar month, date wheel 50 changed day pawl 42 by Pressure and rotate 1 step, day needle 7 takes the needle 1 day amount as a result,.In addition, according to calendar mechanism 10, in the moon in addition to 2 months in the small middle of the month Last day, the end of month pawl 53 by date in solar month of 30 days feeding claw 35 press and make date wheel 50 rotate 1 step after, 50 quilt of date wheel It changes the pressing of day pawl 42 and further rotates 1 step, day needle 7 takes the needle 2 days amounts as a result,.In addition, according to calendar mechanism 10, in the leap year 2 months last days, the end of month pawl 53 by date in solar month of 30 days feeding claw 35 press and make date wheel 50 rotate 2 steps after, the date Wheel 50 is changed the pressing of day pawl 42 and further rotates 1 step, and day needle 7 takes the needle 3 days amounts as a result,.In addition, according to calendar mechanism 10, In 2 months last days in non-leap year, is pressed in the end of month pawl 53 by date in solar month of 30 days feeding claw 35 and date wheel 50 is made to rotate 3 steps Afterwards, date wheel 50 is changed the pressing of day pawl 42 and further rotates 1 step, and day needle 7 takes the needle 4 days amounts as a result,.

Moreover, in the transfer in first day of from the last day from the moon to next month, pointer release link 70 is from final position to first Beginning position is mobile, as a result, the month wheel teeth portion 81 of the feeding claw moon, wheel 75 pressing month 80.Also, when month gear teeth portion 81 is by the moon Feeding claw 75 press and when being rotated with predetermined angular along the direction CCW, the moon locating rod 86 terminal part 87 and month wheel teeth portion 81 It is fastened on after temporarily being released and engages once more.Month wheel 80 and month cam 27 are as a result, with 30 ° of spacing 1 step of rotation.As a result, The month display panel 5 for taking turns 80 linkages with month can be made to rotate, so as to feed month.In addition, at this point, month cam 27 it is convex The position of portion 27a~27e and year cam 28 also changes.Therefore, date in solar month of 30 days feeding claw 35 can be with the solar month, the small middle of the month 2 months of the moon, leap year in addition to 2 months and 2 months of non-leap year correspondingly shift.

By executing above-mentioned movement repeatedly, calendar mechanism 10 takes turns the 1 of 50 in execution date last day in the solar month as a result, 1 feed ration of the date feeding and day needle 7 of feed ration takes the needle, in execution date last day of the moon in addition to 2 months in the small middle of the month 2 feed rations of the date feeding and day needle 7 of 2 feed rations of wheel 50 took the needle, at 3 days of 2 months 29 execution dates wheel 50 in leap year The date feeding of amount and 3 feed rations of day needle 7 take the needle, 2 months 28 execution dates wheel 50 in non-leap year 4 feed rations date into To taking the needle for 4 feed rations with day needle 7, to carry out the display on date.In addition, the calendar mechanism 10 of present embodiment the moon most The latter rotation of angel's month display panel 5 carries out the display in month to feed month.

As set forth in more detail above, according to the present embodiment, without as prior art using complicated planetary gear machine Structure, can be by solar month of 30 days date finger driving wheel 25, date in solar month of 30 days feeding claw 35 and date wheel 50 with the end of month pawl 53 simply to tie Structure constitutes calendar mechanism 10.In addition, date in solar month of 30 days feeding claw 35 is removing 2 months for 30 days small middle of the month below in 1 month number of days The last day of the moon in addition presses the end of month pawl 53 and date wheel 50 is made to rotate the 1st angle, and in 2 months last days in leap year Therefore the 2nd angle for pressing the end of month pawl 53 and keeping the 1st angle of 50 speed ratio of date wheel big can make the 2 months the end of month in the leap year The number of days of the date feeding of execution is more than the number of days for the date feeding that the end of month of the moon in addition to 2 months in the small middle of the month executes.Separately Outside, date in solar month of 30 days feeding claw 35 presses the end of month pawl 53 in 2 months last days in non-leap year and makes the 2nd angle of 50 speed ratio of date wheel The 3rd big angle, therefore, the number of days that the date executed at the 2 months the end of month in non-leap year can be made to feed is than 2 months moons in the leap year The number of days for the date feeding that end executes is more.Accordingly, for the date feeding at the 2 month the end of month carried out manually in the prior art, nothing By can be carried out automatically in non-leap year or in the leap year.Moreover, because last day of date in the solar month of 30 days feeding claw 35 in the solar month of 30 days The end of month pawl 53 is pressed rotate date wheel 50, therefore, can be made during the load that following wheels fasten application is increased only In the last day in solar month of 30 days: the train drives the solar month of 30 days date finger driving wheel 25 for being provided with date in solar month of 30 days feeding claw 35.Therefore, It is capable of providing following calendar mechanism 10: can simply form, and be able to suppress the load for being applied to train, either flat Year or the date feeding that the 2 month the end of month can be automatically carried out in the leap year.

In addition, calendar mechanism 10 has date in the solar month of 30 days feed bar 30 rotated around month cam 27, date in the solar month of 30 days feeding Bar 30 has the sliding contact pawl 34 with the outer peripheral surface sliding contact of the outer peripheral surface and year cam 28 of month cam 27.Month cam 27 Outer peripheral surface includes multiple 1st protrusion 27b~27es corresponding with the moon in addition to 2 months in the small middle of the month；The corresponding 2nd with 2 months Protrusion 27a.Year, the outer peripheral surface of cam 28 had the 3rd protrusion 28a, and the 3rd protrusion 28a is by year cam 28 from transferring in non-leap year 2 months, when from the end on observation of the 1st axis C1 with the 2nd protrusion 27a side by side, and seen at 2 months of the leap year, from the axial direction of the 1st axis C1 Keep out of the way when examining from the position of the 2nd protrusion 27a side by side.

According to this structure, in the sliding contact pawl 34 and the 1st protrusion 27b~27e, the 2nd protrusion of date in solar month of 30 days feed bar 30 Which when any protrusion sliding contact in 27a and the 3rd protrusion 28a, can not be slided for sliding contact pawl 34 and protrusion It moves the state of contact and shifts date in solar month of 30 days feed bar 30.Since the 2nd protrusion 27a is being upwardly formed around the 1st axis C1 in week It is bigger than the 1st protrusion 27b~27e, therefore, make date in solar month of 30 days feed bar 30 after sliding contact pawl 34 and the 2nd protrusion 27a sliding contact The time of displacement becomes than making the date in solar month of 30 days after any protrusion sliding contact in sliding contact pawl 34 and the 1st protrusion 27b~27e The time that feed bar 30 shifts is long.As a result, date in solar month of 30 days feed bar 30 2 months last angel's date in solar month of 30 days feeding claw 35 with The time that the end of month pawl 53 engages becomes smaller in last angel of the moon in addition to 2 months in the small middle of the month than date in solar month of 30 days feed bar 30 The time that month date feeding claw 35 engages with the end of month pawl 53 is long.

Moreover, the 3rd protrusion 28a at 2 months of non-leap year, when from the end on observation of the 1st axis C1 with the 2nd protrusion 27a side by side, and Keep out of the way at 2 months of the leap year, when from the end on observation of the 1st axis C1 from the position of the 2nd protrusion 27a side by side, therefore, with the leap year It compares within 2 months, at 2 months of non-leap year, date in solar month of 30 days feed bar 30 was for sliding contact pawl 34 and the not sliding contacts of which protrusion State and time for shifting it is elongated.Date in solar month of 30 days feed bar 30 is fed on 2 months last angel's dates in solar month of 30 days in non-leap year as a result, The time that pawl 35 engages with the end of month pawl 53 becomes 2 months last angel's date in solar month of 30 days than date in solar month of 30 days feed bar 30 in the leap year The time that feeding claw 35 engages with the end of month pawl 53 is long.

According to the above, date in solar month of 30 days feeding claw 35 can the last day of 2 months of leap year press the end of month pawl 53 and The 2nd angle for keeping the 1st angle of 50 speed ratio of date wheel big, so as to the date feeding for executing the 2 months the end of month in the leap year Number of days be more than the small middle of the month the moon in addition to 2 months the end of month execute date feeding number of days.In addition, the date in solar month of 30 days feeds Pawl 35 can make big the 3rd jiao of the 2nd angle of 50 speed ratio of date wheel in the last day of 2 months of non-leap year pressing the end of month pawl 53 Degree, therefore, the number of days that the date executed at the 2 months the end of month in non-leap year can be made to feed is than the 2 months the end of month execution in the leap year The date number of days of feeding is more.Therefore, it is capable of providing such calendar mechanism 10: either still can be certainly in the leap year in non-leap year The date feeding at the 2 month the end of month is carried out dynamicly.

In addition, calendar mechanism 10 makes the intermittently rotation of year cam 28 by Geneva mechanism 90.Thereby, it is possible to be arranged to keep year convex Wheel 28 relative to month cam 27 it is static during.Therefore, with year cam continuously rotation the case where compared with, be easy at 2 months The end of month makes year cam 28 be located at defined rotation position.Therefore, date in solar month of 30 days feed bar 30 can reliably be made desirably Track displacement, so as to reliably carry out the date feeding at the end of month in solar month of 30 days.

Defined angle is carried out to the slewing area of date in solar month of 30 days feed bar 30 in addition, being provided on solar month of 30 days date finger driving wheel 25 Determine pin 37.Thus, for example being located at the state etc. of the opposite side of date wheel 50 across the 1st axis C1 in date in solar month of 30 days feed bar 30 Under, the slewing area of date in solar month of 30 days feed bar 30 is prescribed, so as to prevent date in solar month of 30 days feed bar 30 and other components Unexpected contact.Thereby, it is possible to inhibit to generate unfavorable condition in comprising the various mechanisms including calendar mechanism 10.

In addition, being formed with side 55a on the end of month pawl 53, the side 55a is contacted with date in solar month of 30 days feeding claw 35, will be with Date in the solar month of 30 days feeding claw 35 of 25 synchronous rotary of solar month of 30 days date finger driving wheel is pressed to the direction for leaving the end of month pawl 53.Thereby, it is possible to will be small Month date feeding claw 35 is pressed to the direction for leaving the end of month pawl 53, it is therefore not necessary to using to date in solar month of 30 days feeding claw 35 to leaving The force application part of the direction force of the end of month pawl 53, it will be able to make date in solar month of 30 days feeding claw 35 leave the end of month pawl 53 in the solar month.As a result, Can prevent following situations: in the solar month, date in solar month of 30 days feeding claw 35 presses the end of month pawl 53 and rotates date wheel 50.Therefore, energy Enough prevent the malfunction of calendar mechanism 10.

In addition, date wheel 50 is rotated centered on the 2nd axis C2 since month wheel 80 is rotated centered on the 1st axis C1, because This can distinguish the moon for being freely laid out and taking turns 80 linkages month compared with month takes turns and date wheel is by the structure of arranged coaxial Part display panel 5 and the day dates display member such as needle 7 to link with date wheel 50.Therefore, it is capable of forming following calendar mechanism 10: can simply form, and the freedom degree of the display layout of the day moon is excellent.

Also, machine core 100 and clock and watch 1 according to the present embodiment, due to having following calendar mechanism 10: can be simple Ground is constituted, and is able to suppress the load for being applied to train, either still can automatically carry out 2 month in and month out in the leap year in non-leap year The date feeding at end, therefore, is capable of providing reliability and convenience all excellent machine core 100 and clock and watch 1.
