BACKGROUND OF THE INVENTION
The present invention relates to a structure of an electronic timepiece with a solar cell.
[0002]
[Prior art]
Conventionally, timepieces have two display modes: an analog system that displays time using two or three hands and a digital system that displays time using an electro-optical display device typified by liquid crystal or LED, or both. It is well known that it can be broadly classified into a combined combination system. In addition, among analog timepieces, for example, the user has the presence or absence of a second hand or calendar, and the presence or absence of a subordinate timekeeping function represented by a timer function, a chronograph function, an alarm function, a moon age display function, etc. It is also well known that it can be selected according to the user's preference.
[0003]
Among these, in the case of an analog type clock with a calendar mechanism for displaying the date other than the normal time, the date display position is often at 3 o'clock, but the date display position is arranged at 4 o'clock or 6 o'clock. It is also well known that there are clocks that can be selected by users according to their preferences.
[0004]
In addition, watches have been mainly used as a driving power source in the past by hand-winding or non-rechargeable primary batteries, but recently rechargeable rechargeable batteries using rechargeable secondary batteries. Watches are becoming popular.
[0005]
Examples of rechargeable timepieces that use a secondary battery as a driving power source include timepieces with solar cells that use solar cells that generate power by receiving light, and self-winding timepieces that generate electricity by rotating weights with the movement of their arms. Etc.
[0006]
Among these, the basic structure of a calendar-equipped analog electronic timepiece using a solar cell as a power source will be described below with reference to the drawings. FIG. 8 is a plan view of a main part of a conventional analog timepiece with a solar cell with a calendar mechanism, and FIG. 9 is a cross-sectional view of the main part.
[0007]
In FIG. 8, 1 is a base material of the watch body, a ground plate that is a component that holds the components of the watch, such as a reverse gear train that is not shown, and a time adjustment mechanism by a winding stem, 2 is a solar cell, 3 is a dial, 4 is a circuit that is a component that drives a watch, 5 is a disk-shaped component that prints the date, a date plate that is a rotating member that displays the date to the user at a predetermined position, and 6 and 7 are sun A solar cell connection spring that is a spring component that electrically connects the battery 2 and the circuit 4, 6 is a solar cell connection spring that connects the solar cell anode and the circuit, and 7 is a solar cell cathode and circuit. It is a solar cell connecting spring.
[0008]
In FIG. 8 and FIG. 9, the dial 3 is formed of a material that transmits light, and power is generated by applying light to the solar cell 2 disposed between the dial 3 and the ground plate 1. In this way, by adopting a structure in which the solar cell 2 is disposed on the dial 3 side, the watch is exposed when it is carried on the arm, and the solar cell 2 is always exposed to light through the dial 3. The solar cell 2 can generate power. As a result, the battery can be efficiently charged even when carried.
[0009]
Further, a + electrode 2 a and a − electrode 2 b are formed on the surface of the solar cell 2 on the ground plate 1 side, and are electrically connected to the circuit 4 by solar cell connection springs 6 and 7, respectively. As a result, when the solar cell generates power, the generated current is conducted to the pattern formed in the circuit 4 by the solar cell connection springs 6 and 7 and stored in a secondary battery (not shown). In actual hand movement, a current is supplied to the secondary battery from a secondary battery to drive a hand movement motor (not shown), thereby realizing stable hand movement even when the solar cell 2 does not receive light and does not generate power, such as at night.
[0010]
The date plate 5 is disposed between the main plate 1 and the solar cell 2. Here, since the solar cell 2 is formed of a material that does not transmit light, a date display window 2c is formed on the solar cell 2 and a date display window 3a is formed on the dial 3 at a place where the date is displayed on the completed clock. Thus, the user can confirm the current date.
[0011]
In addition, island shapes 1 a to 1 d are arranged on the outer peripheral side of the main plate 1. Further, notches 2d to 2g are formed on the outer peripheral portion of the solar cell 2 at positions corresponding to the island shapes 1a to 1d. Here, with respect to the island shapes 1a and 1b and the cutouts 2d and 2e of the solar cell 2, the plane gap is set to a minimum. Accordingly, the position of the solar cell 2 is regulated with respect to the ground plane 1.
[0012]
Further, the upper surfaces of the island shapes 1 a to 1 d are set so as to protrude from the upper surface of the solar cell 2 toward the dial plate 3, and the upper end surfaces thereof are in contact with the dial plate 3. Thereby, a fixed cross-sectional space is ensured between the solar cell 2 and the dial 3 in the completed timepiece state, and interference fringes are prevented from being generated due to the contact between the solar cell 2 and the dial 3. In addition, the solar cell 2 and the dial 3 are prevented from contacting when an impact is applied to the completed timepiece.
[Problems to be solved by the invention]
The problem here is how to produce these products at low cost when displaying dates at various positions according to the user's preference.
[0013]
That is, as described above, in the case of an analog timepiece equipped with a calendar mechanism, it is necessary to set the date display position to an arbitrary position not only based on the 3 o'clock position but also according to the user's preference and the design of the completed clock. Arise. As the date display position, there are many 4 o'clock positions and 6 o'clock positions other than the normal 3 o'clock position, but examples of special positions include the 8 o'clock position, 9 o'clock position, and 12 o'clock position.
[0014]
In order to produce products having specifications with different date positions, it is necessary to newly set a solar cell in which the date display window 2c is disposed at a position corresponding to each date display position. As a result, it is necessary to newly set the solar cells 2 by the number of types having different date display positions, which causes an increase in production cost of parts.
[0015]
In order to prevent this, a method in which the date display window 2c is provided in advance for the type of date display position in the solar cell 2 can be considered. If it is set as such a shape, all the solar cells 2 can be used in common regardless of the date display position. However, since the dial plate 3 is formed of a material that transmits light, the date display window disposed in the solar cell 2 is transparent through the dial plate 2, for example, a calendar disposed under the unused date display window. There is a problem that the members and the like can be seen and the appearance quality is deteriorated.
[0016]
Moreover, if the number of date display windows corresponding to each date display position is increased, the power generation possible area of the solar cell 2 is reduced, resulting in a problem that the charging efficiency of the solar cell is lowered.
[0017]
In order to solve these problems, the present invention realizes a structure in which a solar cell can be used in common without being a new part in a plurality of types of analog electronic timepieces with a solar cell having different specifications for the date display position of the calendar function. Is.
[0018]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an essential part of an analog timepiece with a solar battery having a date display position of 3 o'clock specification according to an embodiment of the present invention. The same structure as that in FIGS. 8 and 9 is given the same name and its description is omitted.
[0029]
In FIG. 1, a total of four island shapes 1 a to 1 d are formed on the ground plane 1. Here, unlike the conventional example, these four island shapes are characterized by being formed at equal angular intervals of 90 °. Further, in the outer peripheral portion of the solar cell 2, notches 2d to 2g were formed at positions corresponding to the island shapes 1a to 1d, and notches 2h to 2k were formed at positions rotated about 30 ° about the central axis of the pointer. That is, the present embodiment is characterized in that a total of eight notches are formed.
[0030]
Further, the + electrode 2a and the -electrode 2b are formed on the surface of the solar cell 2 on the side of the base plate 1, but as shown in FIG. 1, each electrode is extended in the circumferential direction of the timepiece module, It is characterized in that it has a large area compared to the electrode. In addition to the + electrode 2a and the -electrode 2b, a + electrode 2m and a -electrode 2n were further formed. That is, this solar cell 2 is characterized in that it normally forms only one set of + electrode and − electrode, whereas it forms a plurality of sets of + electrode and − electrode.
[0031]
As for the four island shapes 1a to 1d formed integrally with the base plate 1, the dial plate 3 is held on the upper end surface as in the conventional example, but the island shapes 1c and 1d are the island shapes 1a and 1b. Compared to the cutout shapes 2f and 2g of the corresponding solar cell 3, it is characterized by a certain flat gap. In addition, the island shapes 1a and 1b minimize the plane gap between the corresponding notched shapes 2d and 2e of the solar cell 3. As a result, the solar cell 2 regulates the position of the solar cell 2 by making the notch shapes 2d and 2e close to the island shapes 1a and 1b of the ground plane 1.
[0032]
Here, the four cutout shapes 2d to 2g formed in the solar cell 2 are formed at positions that form an angle of 90 ° with respect to the center of the watch, but are all the same with respect to the center of the watch. It is characterized by being formed in the shape of That is, these cutout shapes can all be used as position restricting portions for the island shapes 1a and 1b.
[0033]
The outline will be described below. FIG. 2 is a plan view of the main part of the analog timepiece module with solar battery whose date display position is at 6 o'clock. The clock module shown in FIG. 2 prints the date plate 5 so that the date is displayed normally at the 6 o'clock position because the date display position is changed with respect to the clock module shown in FIG. Although the format has been changed, all the other components including the solar cell 2 are characterized in that the components of the timepiece module shown in FIG.
[0034]
That is, in FIG. 1, the solar cell 2 performs position regulation by bringing the notches 2 d and 2 e close to the island shapes 1 a and 1 b of the ground plane 1. On the other hand, in the timepiece module of the specification with different date display positions in FIG. 2, the position is regulated by rotating the solar cell by 90 ° and bringing the cutout shapes 2g and 2f of the outer peripheral portion close to the island shapes 1a and 1b. It is a feature that is done. Thereby, using the solar cell 2, the date display window 2c disposed on the solar cell 2 is moved from the 3 o'clock position to the 6 o'clock position, and the date display position differs only by changing the printing specifications of the date plate 5. It becomes possible to make it the product of specification.
[0035]
Here, although the solar cell 2 and the circuit 4 are electrically connected via the solar cell connection springs 6 and 7, when the date display window 2c is moved by rotating the solar cell 2, the ground plane 1 and the circuit are connected. The relative positional relationship between 4 and the solar cell 2 changes. As a result, the electrodes 2a and 2b of the solar cell 2 and the solar cell connection springs 6 and 7 cannot be connected.
[0036]
On the other hand, in the present embodiment, in the case of a product having a date display position of 3 o'clock specification shown in FIG. 1, the solar cell 2 includes the + electrode 2 a and the − electrode 2 b via the solar cell connection springs 6 and 7. Thus, the pattern formed on the circuit 4 is electrically connected. On the other hand, in the case of the product shown in FIG. 2 in which the date is displayed at the 6 o'clock position, as described above, since the solar cell 2 is rotated 90 ° and incorporated, the + electrode 2m and the −electrode 2n are the solar cells. It has a structure that is electrically connected to the pattern formed on the circuit 4 via the connection springs 6 and 7.
[0037]
As described above, in order to regulate the position of the solar cell 2, the date display position is different by forming a plurality of cutout shapes formed on the outer periphery of the solar cell 2 in the same shape and further forming a plurality of sets of electrodes. The solar cell 2 can be commonly used in a plurality of types of products with specifications, and it has become possible to generalize parts.
[0038]
Next, the case where the solar cell 2 is incorporated in a timepiece module whose date display position is at 4 o'clock is described. FIG. 3 is a plan view of an essential part of an analog timepiece module with a solar battery whose date display position is at 4 o'clock.
[0039]
As described above, with respect to the pair of electrodes of the + electrode 2a and the −electrode 2b formed on the solar cell 2, the shape of each electrode is set to be large. Thus, by rotating and incorporating the solar cell 2 at the 4 o'clock position shown in FIG. 4, the date display window 2 c can be moved to the 4 o'clock position and the solar cells 2 can be used in common.
[0040]
That is, another notch 2h to 2k is formed on the outer peripheral portion of the solar cell 2 at a position obtained by rotating four notches 2d to 2g by 30 °. Accordingly, when the date display window 2c is moved to the 4 o'clock position, the position of the solar cell 2 is regulated by the notches 2d and 2e and the island shapes 1a and 1b of the ground plane 1 in FIG. It is characterized in that the positions are regulated by the notches 2k and 2j and the island shapes 1a and 1b of the ground plane 1. This makes it possible to move the date display window 2c to the 4 o'clock position in common with the ground plane 1 and the solar cell 2 in a plurality of types of watches having different date display positions shown in FIGS.
[0041]
Further, with respect to the + electrode 2a and the -electrode 2b of the solar cell 2, even if the solar cell 2 is rotated by 30 °, the electrodes are connected to the positions where the + electrode 2a and the -electrode 2b are directly above the solar cell connection springs 6 and 7. The range has been extended. When the date display position shown in FIG. 1 is the 3 o'clock position specification and when the date display position shown in FIG. 3 is the 4 o'clock position specification, the rotation angle of the solar cell 2 is 30 °. Even if it rotates, conduction | electrical_connection of the solar cell connection springs 6 and 7 and + electrode 2a and-electrode 2b is not cut | disconnected.
[0042]
When the date display position is at 4 o'clock, as shown in FIG. 3, the dividing line of the solar cell 2 is inclined by 30 °, but printing on the surface of the solar cell 2 has the same color as the power generation unit of the solar cell. Since the dividing line can be made inconspicuous at the time of the completed clock, there is no problem in appearance quality.
[0043]
In this way, by arranging notches for position regulation of the solar cell 2 at equiangular intervals and forming a plurality of sets of electrodes, the solar cell 2 can be used in a plurality of types of timepiece modules with different date display positions. It became possible to use it in common.
[0044]
Next, a second embodiment of the present invention will be described.
[0045]
4 and 5 show a second embodiment of the present invention. FIG. 4 is a plan view of an essential part of an analog timepiece module with a solar cell whose date display position is at 3 o'clock. FIG. 5 is a date display position at 6 o'clock. It is a principal part top view of the analog timepiece module with a solar cell of a position.
[0046]
In FIG. 4, holes 1e and 1f for regulating the positions of the solar cell connection springs 6 and 7 are formed in the vicinity of the outer peripheral portion of the base plate 1, but holes 1g and 1h having the same diameter as the holes 1e and 1f are further added. It is a feature. Further, the holes 1g and 1h are characterized in that the holes 1e and 1f are formed at positions rotated by 90 ° around the center of the clock. Further, the circuit 4 arranged just above the hole 1g is extended with a pattern that conducts to the hole 1e, and the circuit 4 arranged just above the hole 1h is drawn with a pattern that conducts to the hole 1f. There is a feature.
[0047]
In the first embodiment shown in FIG. 1, the + electrode 2 d and the − electrode 2 e are arranged separately from the + electrode 2 a and the − electrode 2 b. On the other hand, in the present embodiment, only one set of the positive electrode 2a and the negative electrode 2b is disposed as the electrode. However, when the solar cell 2 is rotated 90 ° as shown in FIG. 5 so that the date display window 2c is positioned at 6 o'clock, the holes 1g and 1h are directly above the + electrode 2a and the −electrode 2b. It is a feature to come.
[0048]
In this case, when assembling a product having a date display position of 6 o'clock using this solar cell 2, the positions of the solar cell connection springs 6 and 7 are regulated by the holes 1g and 1h, respectively. That is, when the date display position is 6 o'clock, the position of the solar cell connection spring 6 is regulated by the hole 1g. Further, the position of the solar cell connection spring 7 is regulated by the hole 1h. Since the circuit 4 immediately above the holes 1g and 1h is formed with a pattern that is electrically connected to the holes 1e and 1f, the solar cell connection springs 6 and 7 and the circuit 4 can be ensured to be electrically connected.
[0049]
Thus, even when the positive electrode 2a and the negative electrode 2b are moved by rotating the solar cell 2, the solar cell connection spring position regulating holes 1g and 1h are formed at the same angular interval as the rotation angle of the solar cell 2, and the circuit If the pattern 4 is also extended to just above the solar cell position regulating holes 1g and 1h, the built-in positions of the solar cell connection springs 6 and 7 can be changed. As a result, the ground plane 1, the solar cell 2, and the circuit 4 can be used in common even in a plurality of types of products having different specifications for date display positions.
[0050]
Next, a third embodiment of the present invention will be described.
[0051]
FIG. 6 is a plan view of the main part of a multi-needle analog timepiece with a solar battery in which small hands indicating date, day of the week, and 24-hour display are arranged at the 3 o'clock position, 6 o'clock position, and 9 o'clock position, respectively. FIG. 7 is a plan view of the main part of a multi-needle analog timepiece with a solar cell in which small hands are arranged at the 6 o'clock position, 9 o'clock position, and 12 o'clock position, respectively.
[0052]
In FIG. 6, 2p is a relief hole that penetrates the central axis of the date display small hand, 2r is a relief hole that penetrates the central axis of the day display small hand, and 2s is a relief hole that penetrates the central axis of the 24-hour display small hand.
[0053]
Also in FIG. 6, similarly to the example shown in FIG. 1, notches for regulating the position of the solar cell 2 are arranged in a total of four locations of 2d to 2g, and further, the notches are arranged at equal angular intervals of 90 °. Is the feature. Further, the positive electrode 2a is arranged at a position obtained by rotating the positive electrode 2a by 90 °, and the negative electrode 2n is arranged at a position obtained by rotating the negative electrode 2b by 90 °.
[0054]
FIG. 7 shows a case where the solar cell 2 is incorporated in a timepiece module having different specifications for calendar display. In the case of FIG. 6, the position of the solar cell 2 is regulated by the notches 2d and 2e, and the solar cell 2 is electrically connected to the circuit 4 by the + electrode 2a and the -electrode 2b. On the other hand, in the case of FIG. 7, since the solar cell 2 is rotated by 90 ° compared to the example of FIG. 6, the position of the solar cell 2 is regulated by the notch 2g and the notch 2h. The positive electrode 2m and the negative electrode 2n are electrically connected to the circuit 4.
[0055]
In this way, not only the analog clock with solar battery with multiple types of calendars with different date display positions, but also a multi-hand with a small hand for calendar display and a chronograph function, or an analog with multi-function solar battery The present invention can also be applied to a clock or an analog clock equipped with a rotating member that displays AM / PM, as long as the distance from the clock center is the same. That is, the application range of the present invention is very wide, and the effect is great.
[0056]
【The invention's effect】
