Description of the Prior Art [0002] As an analog electronic timepiece, there are known electronic timepieces having a module for a clock mechanism comprising a plate forming a substrate for this module, provided with an engine incorporated in the platen, and which is rotated on the basis of the actuation of the stepping motor, and a gear train for supporting rotating manner at least a portion of the gear train (see, for example, Patent Document 1 (JP-A-2000-81 491)). In the module for clock mechanism described in the first patent document, a second needle is attached to a second mobile (that is to say a pinion combined with a wheel), a minute hand is attached to the center mobile, and an hour hand is fixed to a moving hour.
In recent years, we have also seen a demand for analog electronic timepieces able to display information other than time with characters or signs and needles, displayed clearly on a dial with needles. However, in the module for a watch mechanism disclosed in the first patent document described above, the second mobile, the center mobile, and the hour mobile, to which the hands are fixed, are arranged coaxially and configured to turn into mutual synchronization with a motor. Therefore, in the timepiece including such a module, it is difficult to display several types of information simultaneously.
SUMMARY OF THE INVENTION
Therefore, the present invention provides a module for a watch mechanism, a movement, and a timepiece capable of simultaneously displaying several kinds of information.
The watch mechanism module according to the present invention comprises: a first output shaft to which a first needle is fixed; a second output shaft to which a second needle is attached, the second output shaft rotating about an axis different from the central axis of the first output shaft; a first motor that drives the first output shaft; and a second motor that drives the second output shaft.
According to the present invention, the second output shaft is driven by a second motor different from the first motor which drives the first output shaft. The second output shaft rotates about an axis different from that of the first output shaft. Therefore, it is possible to cause the second hand to indicate different information from that indicated by the first needle attached to the first output shaft. Therefore, it is possible to provide a watch mechanism module capable of simultaneously displaying several kinds of information.
In the clock mechanism module described above, it is desirable for a plurality of first output shafts to be arranged coaxially.
According to the present invention, it is possible to set respectively several first needles to the first output shafts. Therefore, the present invention is suitable when specific information is indicated by a plurality of needles which rotate about a same axis, for example, when the hour and minute are respectively indicated by an hour hand and a needle. minutes.
In the clock mechanism module described above, it is desirable for the clock mechanism module to comprise: a gear train which transmits a driving force from the second motor to the second output shaft; and a platen which carries the gear train, the gear train comprising a wheel attached to the second output shaft, a projecting section oriented outward in a radial direction of the first output shaft being formed at a edge of the plate, and the projecting section being arranged to cover at least a portion of the wheel when the latter is viewed in the axial direction of the first output shaft.
The watch mechanism module viewed in the axial direction of the first output shaft tends to expand as the distance between the first output shaft and the second output shaft increases. According to the present invention, the projecting section formed at the edge of the plate covers at least a portion of the wheel fixed to the second output shaft. Therefore, the outer shape of the platen is designed so that it extends along the shape of the wheel. Therefore, compared to a configuration in which the plate carrying the wheel does not have a projecting section, it is possible to reduce the platen surface seen from the axial direction of the first output shaft. Thus, it is possible to prevent any increase in the size of the watch mechanism module.
In the module for clock mechanism described above, it is desirable that the module for clock mechanism comprises: a first wheel fixed to the first output shaft, and a second wheel fixed to the second output shaft; the second wheel is arranged so that it covers the first wheel when it is viewed in the axial direction of the first output shaft.
According to the present invention, the first wheel attached to the first output shaft and the second wheel attached to the second output shaft are arranged so that they overlap each other. Therefore, the present invention is suitable in a situation where the first output shaft and the second output shaft are disposed close to each other.
In the module for clock mechanism described above, it is desirable that the module for a clock mechanism comprises: a third output shaft to which a third needle is fixed, the third output shaft rotating about an axis different from the central axis of the first output shaft and a central axis of the second output shaft; and a third motor that drives the third output shaft.
According to the present invention, the third output shaft is driven by a third motor different from the first motor which drives the first output shaft and the second motor which drives the second output shaft. The third output shaft rotates about an axis different from that of the first output shaft and the second output shaft. Therefore, it is possible to cause the third needle to indicate information different from that indicated by the first needle attached to the first output shaft and those indicated by the second needle attached to the second output shaft. Thus, it is possible to provide a watch mechanism module capable of simultaneously displaying several kinds of information.
A movement according to the present invention comprises the module for clock mechanism described above.
According to the present invention, the movement comprises a module for a watch mechanism as explained above. Therefore, it is possible to perform a movement capable of simultaneously displaying different kinds of information.
A timepiece according to the present invention comprises the movement described above, as well as the first needle and the second needle.
According to the present invention, the timepiece comprises a movement as described above. Therefore, it is possible to simultaneously display a plurality of kinds of information using the first needle and the second hand.
In the timepiece, it is desirable for the distance between the central axis of the second output shaft and the distal end of the second needle to be greater than that between the central axis of the second output shaft. and the first output shaft, and that the rotation amplitude of the second needle extends along a fan-shaped sector.
According to the present invention, it is possible to rotate the second needle at an amplitude that allows it to not come into contact with the first output shaft. Thus, compared to the case where a rotation amplitude set at 360 ° for the second hand is used, it is possible to provide a timepiece capable of indicating, with a second longer needle, information different from that indicated by the first needle.
In the timepiece described above, it is also desirable that the distance between the central axis of the second output shaft and the distal end of the second needle is adjusted to be smaller than the distance between the central axis of the second output shaft and the first output shaft, so that the rotation amplitude of the second needle can be totally circular.
According to the present invention, it is possible to make a complete rotation of 360 ° to the second hand. Therefore, it is possible to rotate and move the second hand in any position only through a steady rotation drive by the second motor. In other words, when the second motor is a stepper motor, it is possible to rotate and move the second needle in any position based only on regular rotational pulse inputs applied to the second motor. Thus, compared to a configuration where the rotation amplitude of the second hand is limited to an angle smaller than 360 °, it is possible to control the second motor more easily.
[0023] A timepiece according to the present invention comprises: a movement comprising the module for clock mechanism described above; the first needle; the second needle; and a third needle.
According to the present invention, the timepiece comprises the movement described above. Therefore, it is possible to display several types of information simultaneously with the first hand, the second hand, and the third hand.
In the timepiece described above, it is desirable that the distance between the central axis of the second output shaft and the distal end of the second needle is adjusted to be greater than that between the central axis of the second output shaft and the first output shaft, that the distance between the central axis of the third output shaft and the distal end of the third needle is adjusted to be greater than that between the central axis of the third output shaft and the first output shaft, that the amplitude of rotation of the second hand and that of the third hand extend over fan-shaped sectors, and that the sum of the central angles respectively corresponding to the the amplitude of rotation of the second hand and that of the third hand is greater than 360 °.
According to the present invention, compared to the case when using a needle whose rotation amplitude is set to 360 °, it is possible to indicate, with the second longer needle and the third longer needle, information different from that indicated by the first needle so that they can be visually easily recognizable. In addition, the sum of the central angles corresponding to the rotation amplitude of the second hand and to that of the rotation amplitude of the third hand is greater than 360 °. Therefore, compared to the case where information different from that indicated by the first needle is indicated using only one needle, the maximum rotation amplitude of which is at most 360 °, it is possible to indicate more kinds of information. Therefore, it is possible to provide a timepiece that can display a greater number of information that can be visually easily recognizable.
According to the present invention, it is thus possible to provide a module for a watch mechanism capable of simultaneously displaying several kinds of information.

(Module frame) [0074] FIG. 9 is a bottom view of the movement according to the first embodiment seen from the rear.
As shown in FIG. 9, the module frame 25 is formed of, for example, a resin material and has a disk shape having substantially the same diameter as the circuit block 23 (see Fig. 2). A module layout hole 25a is formed in the module frame 25. The layout module hole 25a passes through the center of the module frame 25 from side to side in the axial direction. The module layout hole 25a has a shape corresponding to the watch mechanism module 21 when seen from the axial direction. The watch mechanism module 21 is disposed in the module layout hole 25a. As shown in FIG. 2, the watch mechanism module 21 is fixed to the module frame 25 in a state in which it is fixed to the circuit block 23 by a plurality of screws 60.
In this way, the module for clock mechanism 21 according to this embodiment comprises the first output shaft 81 (the mobile hours 33 and the mobile center 36) to which the hour hand 12 and the needle of the 13 minutes are fixed and the second output shaft 82 (the wheel shaft 39a) to which the indicator needle 14 is fixed, the second output shaft 82 rotating about the second axis of rotation P1 different from the first axis of rotation O, which is the center axis of the first output shaft 81. In addition, the watch mechanism module 21 comprises the first step motor 40A and the second step motor 40B which drive the first output shaft 81, and the third stepper motor 40C which drives the second output shaft 82.
The movement 10 according to this embodiment comprises the module for clock mechanism 21.
In this configuration, the second output shaft 82 is driven by the third stepper motor 40C different from the first stepping motor 40A which drives the first output shaft 81. The second output shaft 82 rotates around a axis different from that of the first output shaft 81. Therefore, it is possible to cause the indicator hand 14 to indicate information different from the time information indicated by the hour hand 12 and the minute hand. 13, which is attached to the first output shaft 81. Therefore, it is possible to provide a watch mechanism module 21 and a movement 10 capable of simultaneously displaying a plurality of kinds of information.

Therefore, compared to a configuration in which a pair of output shafts is provided using two modules, it is possible to reduce the space occupied by the module of the watch mechanism. Therefore, it is possible to reduce the size of the timepiece equipped with the watch mechanism module 21.
The hour wheel 33a and the center wheel 36a fixed to the first output shaft 81 and the indicator wheel 39b fixed to the second output shaft 82 are arranged so that they overlap each other when they are seen from the axial direction. Therefore, it is possible to place the first output shaft 81 and the second output shaft 82 close to each other.
The timepiece 1 according to this embodiment comprises the movement 10, the hour hand 12 and the minute hand 13, and the indicator hand 14. Therefore, it is possible to make a piece watchmaker capable of simultaneously displaying a plurality of kinds of information.
The distance between the second axis of rotation P1 and the distal end of the indicator needle 14 is determined such that it is longer than the distance between the second axis of rotation P1 and the first output shaft. 81. The amplitude of rotation of the indicator needle 14 extends over a fan-shaped sector. Therefore, it is possible to rotate the indicator needle 14 along an angular sector in which the indicator needle 14 is not brought into contact with the first output shaft 81. Thus, compared to the case where an indicator needle whose rotation amplitude is defined as being equal to 360 ° is used, it is possible to provide a timepiece 1 capable of indicating, with a longer indicator hand 14, a different information from the time information indicated by the hour hand 12 and the minute hand 13.
The concave section 58 is formed in the gear train deck 52 in a position opposite to that of the center wheel 36 in the axial direction. Therefore, it is possible to remove the second plug 59 and the indicator mobile 39 and to have a second mobile, which meshes with the fifth mobile 38, between the lower surface of the concave section 58 and the center wheel bridge 54 ( see a fifth embodiment explained below). Part of the shaft of the second mobile is inserted inside the center mobile 36. Thus, it is possible to arrange a third needle which rotates coaxially with respect to the hour hand 12 and the minute hand 13. Therefore, it is possible to make a watch mechanism module 21 which can easily switch from a configuration in which an output shaft is provided in one place to a configuration in which output shafts are arranged in two places. different.

A module layout hole 125a is formed in the module frame 125. The module layout hole 125a passes right through the module frame 125 at its center in the axial direction. The module layout hole 125a has a shape corresponding to the clock mechanism module 121 when the latter is viewed in the axial direction. The watch mechanism module 121 is disposed in the module disposition hole 125a.

[0154] (Module Frame) [0155] FIG. 28 is a bottom view of the movement according to the fourth embodiment seen from the rear.
As shown in FIG. 28, the module frame 325 is formed of, for example, a resin material and has a disk shape having substantially the same diameter as the circuit block 23 (see Fig. 23). A module layout hole 325a is formed in the module frame 325. The module layout hole 325a passes through the module frame 325 from one end to the other in the axial direction. The module layout hole 325a has a shape corresponding to the clock mechanism module 321 when seen from the axial direction. The watch mechanism module 321 is disposed in the module layout hole 325a. As shown in FIG. 23, the watch mechanism module 321 is fixed to the module frame 325 in a state where it is fixed to the circuit block 23 by a plurality of screws 60.
In this way, the clock mechanism module 321 according to this embodiment comprises the first output shaft 81 (the hours mobile 33 and the center mobile 236) to which the hour hand 12 and the hour hand. 13 minutes are set, the second output shaft 382 (the wheel shaft 332a) to which the first indicator needle 314A is attached, the second output shaft 382 rotating about the second axis of rotation P3, and the third output shaft 383 (The wheel shaft 39a) to which the second indicator hand 314B is attached, the third output shaft 383 rotating about the third axis of rotation P4.

In this embodiment, the movement 310 includes the watch mechanism module 321. Therefore, according to this embodiment, it is possible to undo so that the second indicator needle 314B indicates information. different from those indicated by the hour hand 12 and the minute hand 13 attached to the first output shaft 81 and information indicated by the first indicator hand 314A attached to the second output shaft 382. Therefore, it is possible to to make the clock mechanism module 321 capable of simultaneously displaying several kinds of information.
The clock mechanism module 321 comprises the first output shaft 81, the second output shaft 382 which rotates about an axis different from the axis of the first output shaft 81, and the third output shaft 383 which rotates about an axis different from the axes of the first output shaft 81 and the second output shaft 382. Therefore, compared to a configuration in which three output shafts are arranged using three mechanism modules, it is possible to reduce space occupied by the mechanism module. Therefore, it is possible to reduce the size of a timepiece that would be equipped with the watch mechanism module 321.
According to this embodiment, the hours mobile 33 and the center mobile 236, which are arranged coaxially with respect to each other, are driven by a second stepping motor 40B. Therefore, compared to a configuration in which the hours mobile and the center mobile are driven by two stepper motors, it is possible to reduce the number of components constituting the watch mechanism module 321 and thus reduce in size the module for clock mechanism 321.
The hour wheel 33a and the center wheel 36a fixed to the first output shaft 81 and the indicator wheel 39b attached to the third output shaft 383 are arranged in such a way that they overlap each other when seen from the axial direction. Therefore, it is possible to arrange the first output shaft 81 and the third output shaft 383 close to each other. As a result, it is possible to reduce the external shape of the watch mechanism module 321 viewed along the axial direction.
The distance between the second axis of rotation P3 and the distal end of the first indicator needle 314A is defined as being longer than the distance between the second axis of rotation P3 and the first output shaft 81. The amplitude of rotation of the first indicator needle 314A extends over a fan-shaped sector. Therefore, it is possible to rotate the first indicator needle 314A at an angular magnitude where the first indicator hand 314A is not brought into contact with the first output shaft 81. The same applies to the second indicator needle 314A. indicator needle 314B. Thus, compared to the case where an indicator needle is used with a rotation amplitude set at 360 °, it is possible to indicate, with a longer first indicator needle 314A and a second longer indicator hand 314B, information different from the information indicated by the hour hand 12 and the minute hand 13.
In addition, the sum of the central angle of the rotation amplitude of the first indicator needle 314A and the central angle of the rotation amplitude of the second indicator needle 314B is greater than 360 °. Therefore, compared to the case where information different from the information indicated by the hour hand 12 and the minute hand 13 are indicated using a single needle, the rotation amplitude thereof being 360 ° or less it is possible to indicate a greater number of kinds of information. Therefore, it is possible to provide a timepiece 301 which can display a greater number of kinds of information, which can be visually easily recognizable.
It should be noted that, according to this embodiment, the first indicator needle 314A and the second indicator needle 314B are arranged in the same position in the axial direction. The first sub-display area 316A and the second sub-display area 316B are not arranged to overlap each other when viewed from the axial direction. However, the first indicator needle 314A and the second indicator needle 314B may be arranged in different positions in the axial direction. The first sub-display area and the second sub-display area may be arranged in such a way that they overlap each other when viewed from the axial direction.
