Therefore, the small day indicator 464 always receives a rotational force in the counterclockwise direction. Therefore, the front end portion of the cam contact portion 491c of the first hammer 491 always receives a force of pressing the transmission cam portion 462c of the day indicator transmission wheel 462. In a state where "Sun" representing "Sunday" is indicated by the small day wheel 464, the front end portion of the cam contact portion 491c of the first hammer 491 is pressed against the transmission cam portion 462c of the day indicator transmission wheel 462.

Next, referring to fig. 20, when the day indicator transmission wheel portion 462b of the day indicator transmission wheel 462 is rotated by the day feeding claw 320f (i.e., 1/7) by rotating the hour wheel 262 from the state of indicating "Sun" representing "Sunday" shown in fig. 19, the first hammer 491 is rotated by one day from the state of indicating "Sun". The position in the rotational direction of the day indicator transmission wheel 462 is stopped by the day jumper 468 rotatably provided on the main plate 202. The first operating wheel portion 491f of the first hammer 491 turns the small day wheel 464 by one day so as to enter a state indicating "Mon" representing "Monday". By the spring force of the return spring portion 494c, the small day wheel 464 always receives a rotational force in the counterclockwise direction via the second hammer 492. The first hammer 491 always receives a rotational force in the clockwise direction. The front end portion of the cam contact portion 491c of the first hammer 491 always receives a force of pressing the transmission cam portion 462c of the day indicator transmission wheel 462. Similarly, every day, the small day wheel 464 rotates by one day, from a state indicating "Mon" representing "Monday" to a state indicating "Tue" representing "Tuesday", then to a state indicating "Wed" representing "Wenes day", then to a state indicating "Thu" representing "Thursey", then to a state indicating "Fri" representing "Friday", then to a state indicating "Sat" representing "Saturday", then to a state indicating "Sun" representing "Sunday".

Referring to fig. 21, in a state where "Sat" representing "Saturday" is indicated by the small day wheel 464, the front end of the cam contact portion 491c of the first hammer 491 is pressed against a portion of the transmission cam portion 462c of the day indicator transmission wheel 462 near the maximum radius portion. When the day indicator feeding claw 320f rotates the day indicator transmission wheel portion 462b of the day indicator transmission wheel 462 by one day by rotating the hour wheel 262 in a state in which "Sat" representing "Saturday" is indicated, that is, (1/7), the leading end portion of the cam contact portion 491c of the first hammer 491 moves from a portion near the maximum radius portion and is pressed against a portion of the transmission cam portion 462c of the day indicator transmission wheel 462 near the minimum radius portion. In addition, by adjusting the rotational speed, the cycle, the reduction ratio or the like of the driving means for operating the day indicator feeding mechanism, it is possible to realize a display device which is easy to view, which performs not only day of the week display but also time information ("hour", "minute" or the like) display, day of the week information display, month display, year display, month phase display or the like by moving the small hands in a fan shape by adopting a structure having the day indicator feeding mechanism.

(1.16) operation of the date correction mechanism:

the operation of the date correcting mechanism will be described below. Referring to fig. 1, 2, 4 to 6, in a state where the hand setting stem 210 is pulled out from the 0 stage to the 1 stage, the hand setting stem 210 rotates in one direction, and the fourth corrector setting transmission wheel 354 moves in a direction approaching the date corrector setting wheel 355 via the rotations of the first corrector setting transmission wheel 351, the second corrector setting transmission wheel 352, and the third corrector setting transmission wheel 353, and a wheel portion of the fourth corrector setting transmission wheel 354 can mesh with a wheel portion of the date corrector setting wheel 355. Therefore, the date star wheel 312 can be rotated by rotating the hand setting stem 210 in one direction in a state where the hand setting stem 210 is pulled out to 1 stage, thereby correcting the date.

In a state where the hand setting stem 210 is pulled out to 1 stage, the hand setting stem 210 rotates in the other direction, and the fourth corrector setting transmission wheel 354 moves in a direction away from the date corrector setting wheel 355 via the rotations of the first corrector setting transmission wheel 351, the second corrector setting transmission wheel 352, and the third corrector setting transmission wheel 353. In this state, the wheel portion of the fourth corrector setting transmission wheel 354 is not meshed with the wheel portion of the date corrector setting wheel 355. Therefore, even if the hand setting stem 210 is rotated in the other direction in a state where the hand setting stem 210 is pulled out to 1 stage, the date star wheel 312 cannot be rotated, and the date cannot be corrected.

(1.17) operation of pointer setting:

the pointer setting operation will be described below. Referring to fig. 4, in a state where the hand setting stem 210 is pulled out to 2 stages, the a tooth 274a of the clutch wheel 274 meshes with the setting wheel 278. When the hand setting stem 210 is pulled out to the 2 stage, the spring portion of the hammer 250 rotates and comes into contact with the reset lever 252. Thereby, the spring portion of the hammer 250 is connected with the reset pattern of the circuit board 224 via the reset lever 252, the operation of the integrated circuit 230 is reset, and at the same time, the hammer 250 stops the fourth wheel & pinion 240. By rotating the hand setting stem 210 in a state where the hand setting stem 210 is pulled out to 2 stages, the setting wheel 278 is rotated via the rotation of the clutch wheel 274. By rotating the setting wheel 278, the center pinion of the center wheel & pinion 244 and the hour wheel 262 are rotated via the rotation of the minute wheel 260. When hand setting is performed in a state where the hand setting stem 210 is pulled out to 2 stages, the center pinion of the center wheel & pinion 244 can slide with respect to the center wheel of the center wheel & pinion 244. By rotating the hand setting stem to rotate the center pinion, the minute hand 244h is rotated, and by rotating the hour wheel 262, the hour hand 262h is rotated, so that the time display ("display of hour" and "minute") can be corrected.

(1.18) specification of pointer position and pointer size:

referring to fig. 10 and 11, in the first embodiment of the multifunction timepiece, time information on "hour" of the 12-hour system can be displayed by the hour hand 262h attached to the hour wheel 262 whose rotation center is the main plate center 202c, by means of a minute hand 244h attached to a center wheel & pinion 244, the center of rotation of which is the main plate center 202c, time information on "minutes" is displayed, by a small second hand 340h connected to the second indicator 340 whose rotation center is arranged in the "6 o' clock direction", time information on "second" is displayed, by the date hand 312h attached to the date star wheel 312, the rotation center of which is arranged in the "3 o' clock direction", calendar information on "date" is displayed, calendar information on "day" is displayed by being connected to a day hand 464h whose rotation center is arranged on a "9 o' clock direction" small day wheel 464 and which can move in a fan shape.

However, the distances between the respective centers may also be configured differently. It is preferable to configure that the distance from the main plate center 202c to the rotation center of the day hand 464h is larger than the distance from the main plate center 202c to the rotation center of the date hand 312 h. It is preferable to configure that the distance from the main plate center 202c to the rotation center of the day hand 464h is larger than the distance from the main plate center 202c to the rotation center of the 24 hour hand 330 h.

For example, in order to display time information on "seconds", numerals "10", "20", "30", "40", "50", "60" are provided along the periphery at positions corresponding to the small second hand 340h of the dial 454. For example, in order to display calendar information on "day of the week", english characters "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" are provided along the periphery at positions corresponding to the day hand 464h of the dial 454. Alternatively, in order to display calendar information on "day", numerals, japanese characters, foreign language characters, roman numerals, symbols, or the like may also be used.

Referring to fig. 10 and 12, in the second embodiment of the multifunction timepiece, time information on "hour" of the 12-hour system can be displayed by an hour hand 262h connected to an hour wheel 262 whose rotation center is a main plate center 202c, time information on "minute" can be displayed by a minute hand 244h connected to a center wheel & pinion 244 whose rotation center is the main plate center 202c, time information on "minute" can be displayed by a small second hand 340h connected to a second indicator 340 whose rotation center is arranged in "6 o ' clock direction", time information on "hour" can be displayed by a 24-hour hand 330h connected to a 24-hour indicator 330 whose rotation center is arranged in "12 o ' clock direction", time information on "hour" of the 24-hour system can be displayed by a date hand 312h connected to a date star wheel 312 whose rotation center is arranged in "3 o ' clock direction", calendar information on "date" is displayed, and calendar information on "day" is displayed in a so-called "reverse type" by being connected to a day hand 464h whose rotation center is arranged on a "9 o' clock direction" small day wheel 464 and which can move in a fan shape.

Referring to fig. 13 to 15, the pendulum weight 100 is rotatably coupled to the first clamping plate 32. The pendulum weight 100 is coupled to the first clamping plate 32 via a ball bearing (not shown). A first transfer wheel (not shown) is rotatably coupled to engage a pinion (not shown) of the pendulum weight 100. A claw lever (not shown) is rotatably coupled to an eccentric cam portion (not shown) of the first transfer wheel. A second transfer wheel (not shown) is rotatably coupled to the claw lever to be engaged with the claw portion (not shown). The ratchet teeth (not shown) of the second transfer wheel are configured to engage the pawl portions of the pawl lever. The first transfer wheel (not shown) is rotated according to the rotation of the pendulum weight 100 and according to the operation of the claw lever, and the second transfer wheel is rotated only in a predetermined direction. The mainspring is configured to be wound according to the rotation of a second winding transfer wheel (not shown).

Referring to fig. 13, 16 to 18, the pallet fork holder 140 is preferably made of an elastically deformable material, for example, stainless steel. The pallet fork 130 is preferably made of an elastically deformable material, for example, stainless steel. The spring portion 132 of the pallet fork 130 may be in a straight shape, a curved shape, a U-shape, or other shapes of similar shape. The protuberance 142 of the pallet fork holder 140 engages the detent pin 122 of the setting lever 120 to locate the setting lever 120 and set the translation weight of the barrel assembly 110. According to the mechanical timepiece of the invention, the rising portion 142 of the pallet fork holder 140 is configured to be able to pull out the barrel assembly 110 to the 1 st and 2 nd stages. The guide concave portion 138 of the pallet fork 130 is pressed against the side surface of the front end portion of the setting lever 120 by the spring force of the spring portion 132 of the pallet fork 130.

Next, the operation of the embodiment of the mechanical timepiece will be described. Referring to fig. 13-15, barrel assembly 30 is rotated by the force of a mainspring (not shown). The center wheel & pinion 24 is rotated by rotation of the barrel assembly 30. The third wheel & pinion 34 is rotated by the rotation of the center wheel & pinion 24. The fourth wheel & pinion 40 is rotated by the rotation of the third wheel & pinion 34. In addition, the cannon pinion 28 is simultaneously rotated by the rotation of the second wheel & pinion 24. Minute wheel 90 is rotated by the rotation of quill pinion 24. The hour wheel 80 is rotated by the rotation of the minute wheel 90. The rotational speeds of the respective train wheels are controlled by the operations of the balance spring mechanism 70, the pallet fork 60, and the escape wheel & pinion 50. Therefore, the fourth wheel & pinion 40 rotates one revolution per minute. The cannon pinion 28 and the central wheel & pinion 24 rotate one revolution per hour. The hour wheel 80 rotates one revolution every 12 hours.

The "seconds" is shown by minute hand 40h connected to fourth wheel & pinion 40. "minutes" is indicated by minute hand 28h attached to cannon pinion 28. The "hour" is indicated by an hour hand 80h attached to the hour wheel 80. That is, the fourth wheel & pinion 40, the cannon pinion 28, and the center wheel & pinion 24, the hour wheel 80 are configured as display wheels for displaying time information. The time can be read by the hour hand 80h, minute hand 28h, second hand 40h, and scale on the dial 82, and the like. Next, the winding operation of the mainspring by the automatic winding mechanism will be described. The mechanical timepiece is carried by the wrist. The wrist swings back and forth. According to the rotation of the pendulum weight 100, the pawl lever is operated when the eccentric cam is operated, and the mainspring is wound by rotating an automatic winding transfer wheel (not shown) having ratchet teeth or the like.

The operation of the switching mechanism will be described next. Referring to fig. 13, 16 to 18, in general, when the mechanical timepiece is carried by the wrist, the hand setting stem 110 is arranged at 0 stage. Then, during the correction date, the hand setting stem 110 is pulled out to 1 stage. In this case, the setting lever 120 is rotated. The pallet fork 130 is rotated by the spring force of the pallet fork so that the B-tooth 162B of the clutch wheel 162 is engaged with the first corrector setting transmission wheel 170. When the hand setting stem 110 is rotated in this state, the clutch wheel 162 is rotated, and when the fourth corrector setting transmission wheel 354 is moved in a direction approaching the date corrector setting wheel 355 by the rotation of the first corrector setting transmission wheel 170 via the rotation of the second corrector setting transmission wheel 352, the third corrector setting transmission wheel 353, the wheel portion of the fourth corrector setting transmission wheel 354 can be meshed with the wheel portion of the date corrector setting wheel 355. Therefore, in a state where the hand setting stem 210 is pulled out to 1 stage, the date star wheel 312 can be rotated by rotating the hand setting stem 110 in one direction, thereby correcting the date.

Next, at the time of correction, the hand setting stem 110 is further pulled out to 2 stages. In this case, the setting lever 120 is further rotated. The pallet fork 130 rotates in the opposite direction to the rotation caused by the spring of the pallet fork, so that the a-tooth 162a of the clutch wheel 162 meshes with the minute wheel 90. When the hand setting stem 110 is rotated in this state, the clutch wheel 162 is rotated, and the cannon pinion 28 and the hour wheel 80 are rotated by the rotation of the minute wheel 90 to correct the time display.

Referring to fig. 13 to 15, 17, the hour wheel 80 rotates according to the rotation of the minute wheel 90. The hour wheel 80 rotates one revolution every 12 hours. By the rotation of the hour wheel 80, the date indicator driving wheel 310 rotates. The date star wheel 312 rotates once a day by the date indicator feeding pawl 310f provided at the date indicator driving wheel 310 (1/31). The date star wheel 312 is configured to rotate one turn every 31 days. By the rotation of the hour wheel 262, the day indicator driving wheel 322 rotates. The small day wheel 322 is rotated once a day by the day feeding pawl 320f provided at the day indicator driving wheel 320 (1/7). The small day wheel 322 rotates one turn every 7 days. In addition, the hour indicator 330 is rotated by the rotation of the day indicator driving wheel 320. The hour indicator 330 rotates one turn every 24 hours. Since the second is displayed by the minute hand 40h connected to the fourth wheel & pinion 40, the second indicator 340, the small second hand 340h can be omitted. Alternatively, second hand 40h may be omitted since "seconds" is displayed by small second hand 340 h.
