Description

  The present invention relates to a display device and a timepiece that include a pointer or the like driven by a driving unit such as a step motor, and displays information by indicating a symbol or the like written on a display unit.

  In particular, the present invention relates to a display device that displays a continuous amount with carry.

  Conventionally, such as analog clocks and meter instruments, information such as time is displayed by operating pointers or display boards with symbol figures, etc., and scales or symbols on the display unit. It is known that there is a display device.

  These include a so-called “retrograde” type display that indicates a semi-circular or fan-shaped display area as seen on a meter instrument, in addition to a circular display area as seen on a general analog watch. .

  In recent years, analog clocks that display time, date, day of the week, chronograph timing information, and the like in a so-called “retrograde” display have become popular.

  When displaying the amount of time such as time and date in the so-called “retrograde” display, the pointer gradually moves from one end (start point) to the other end (end point) of the display area, and the pointer reaches the end point and is displayed. When a carry of a value (60 seconds, 60 minutes, 24 hours, 31 days, etc.) occurs, a display in which the pointer quickly returns to the starting point is common.

  A timepiece in which such a “retrograde” type display is applied to 1/10 second, 1/20, 1/100 second display of a chronograph is also known as shown in Patent Documents 1 to 3.

  For example, Patent Document 1 has a fan-shaped chronograph 1/10 second display area, and the chronograph 1/10 second hand is changed from 0/10 seconds to 9 in accordance with the value of the chronograph 1/10 second counter during chronograph timing. / 10 seconds up to 1 scale forward rotation every 1/10 seconds, and 9/10 seconds to 10/10 seconds, that is, 9 scale reverse rotation between 0/10 seconds, A technique for displaying a graph 1/10 second in real time in a fan-shaped display area is disclosed.

Japanese Patent No. 2542939 (Fig. 3) Japanese Patent Laying-Open No. 2007-256066 (FIG. 5) JP-T-2007-522478 (FIG. 1)

  However, when displaying a continuous amount with a carry such as time, since the movement amount per unit time is usually small, it is possible to immediately move a pointer or a symbol to a new designated position. When a carry occurs, the amount of movement becomes very large, and there is a problem that it takes time to move.

  The above problem will be described with reference to the drawings. FIG. 4 is a modification of the chronograph 1/10 second display of the chronograph timepiece described in Patent Document 1.

  From the state of 0/10 seconds in FIG. 4 (A) to the state of 9/10 seconds shown on the left in FIG. 4 (B), it is only necessary to advance one scale (1 step) every 1/10 seconds. There is no particular problem. However, when the chronograph 1/10 seconds shown in FIG. 4B is carried from 9/10 seconds to 10/10 seconds, that is, when the display is 0/10 seconds, the chronograph 1/10 seconds is indicated. The pointer must be reversed at a speed of 9 divisions, that is, 90 Hz in 1/10 second, and it is difficult to realize it by a general normal timepiece electromagnetic conversion means whose reversal speed is about 32 Hz.

  For this reason, in Patent Document 2, the chronograph 1/20 second pointer driving during chronograph timing is a so-called “demo hand movement”, and the chronograph timing value and the indicated value of the pointer are not synchronized, and the chronograph timing is stopped when the timing is stopped. A technique for synchronizing the value and the indicated value of the pointer is disclosed.

  However, the technique of Patent Document 2 has a problem that it is difficult to read the elapsed time during the time measurement because the time value of the chronograph and the indicated value of the pointer are not synchronized during the time measurement of the chronograph.

The chronograph timepiece described in Patent Document 3 is “retrograde” type display of chronograph 1/10 second and 1/100 second, and is stopped except during the stop operation, and the chronograph 1/10 second during the stop operation, By displaying 1/100 second, the above problem is avoided.
However, in the technique of Patent Document 3, since the hands of chronographs 1/10 seconds and 1/100 seconds are usually stopped, there is a drawback in that the performance as a watch and the interest are interesting.

  In addition, although common to the technology of the above-mentioned patent document, when the information normally indicated by a circular display area is indicated by a semicircular or fan-shaped display area, the angle per unit scale is smaller than that of the circular display area, so the scale is Since it is difficult to read and the movement of the pointer becomes small, it becomes a display for presentation and fun.

  An object of the present invention is to solve the above-mentioned problems and to display information such as time by using an operating pointer or a symbol graphic written on a display board and a scale or symbol written on a display unit. In a display device, especially a display device that displays a continuous amount accompanied by a carry such as time, it is possible to display in real time by preventing the amount of movement of the pointers per unit scale from changing greatly, and per unit scale An object of the present invention is to provide a display device that realizes a display with a large amount of movement and high performance.

  In order to solve the above problems, the display device of the present invention has the following configuration.

  In the display device of the present invention, a predetermined section formed by a plurality of unit sections is defined as one period, and the one period is further divided into at least two or more small periods, and each small period unit is linear or arcuate. A display device that includes an index for indicating the unit section and an instruction unit that indicates the index, and the index corresponding to each of the short periods in the traveling direction of the instruction unit, It is characterized by being arranged with an offset that is a non-natural number times the unit interval.

  In the display device of the present invention, the index corresponds to a first small period of the plurality of small periods, and the first index group arranged in a linear shape or an arc shape, and the plurality of small numbers A second index group corresponding to a second small period of the periods and arranged in a straight line or an arc shape, and the indicating means includes the first index group and the second index group. Instructing the first index group in the first short period, and indicating the second index group in the second short period. It is characterized by directing.

  Further, the offset (deviation amount) is half of the unit interval.

  As described above, the display device of the present invention can display an index for indicating a unit section larger than a conventional display that does not divide, by dividing one cycle display into two or more and displaying the index. Since the interval between them can be increased and the amount of movement of the instruction means when moving from the index to the index can be increased, a display with high performance can be realized.

  In the display device of the present invention, the first indicator group and the second indicator group are arranged in an alternately shifted form, and whether the instruction means indicates the first indicator group. It is possible to clearly determine whether the second indicator group is pointed out.

  The display device of the present invention is characterized in that the first index group and the second index group have a difference in appearance.

  As a result, the display device of the present invention can more clearly determine the first index group and the second index group.

  In addition, the display device of the present invention is characterized in that the instruction means includes a first instruction unit that instructs the first index group and a second instruction unit that instructs the second index group.

  As a result, the display device of the present invention can more clearly determine which of the first index group and the second index group is indicated by the instruction means.

  In the display device according to the present invention, the indicator corresponding to a section serving as a partition between the first short period and the second short period may be the indication unit of the first index group and the second index group. It arrange | positions at the both ends in the advancing direction of this.

  The display device of the present invention is characterized in that the separation index has a difference in appearance with respect to the first index group and the second index group.

  As a result, the display device of the present invention assigns the start point or end point of one cycle and half of one cycle to the delimiter index, and displays the end of the indication area when indicating them. It is now possible to judge the progress of the project more clearly. In addition, since the division index is different from other indices in font, color, index size, and the like, it is possible to display more easily.

  The display device of the present invention is disposed in association with the first index group or the second index group, and indicates a traveling direction of the instruction means in the first small period or the second small period. It is characterized by having a figure.

  As a result, when the display device of the present invention reads the index pointed to by the instruction means, it is only necessary to read the index associated with the graphic corresponding to the direction of travel of the instruction means, and the index pointed to by the instruction means can be read more easily. It is like that.

  The display device of the present invention is characterized in that the one cycle is displayed by displaying the small cycle in a folded manner.

As a result, the display device of the present invention can divide one cycle into two sub-cycles without expanding the display area when one cycle is shown, and can display more easily, and the unit section of the instruction means Since the driving amount per hit can be reduced, it is possible to display without using a special means for driving the instruction means.

  In the chronograph timepiece having the display device of the present invention, the unit is 1 / (10 ^ n) seconds (n: natural number), the one period is 10 times the unit, and the small period is The first short cycle and the second short cycle are two.

  As a result, the chronograph timepiece having the display device of the present invention can display an index for performing display such as 1/10 second larger than the conventional one, and can take a larger interval between the indices. Because the amount of movement of the indication means with the chronograph measurement time can be increased, it is possible to realize a highly chronograph display with high performance, and the user can more easily understand the chronograph time. It can be judged visually.

  Further, the date display timepiece equipped with the display device of the present invention is characterized in that the unit is one day and the one period is 31 days.

  Thus, the date-attached timepiece equipped with the display device of the present invention can display an index for representing the date larger than that of the conventional one, and can take a larger interval between the indices. In addition to realizing the display, the user can more easily understand and visually determine the current date.

  Moreover, the timepiece with age display provided with the display device of the present invention is characterized in that the one cycle is a moon age cycle, and the index is a shape of a moon in the moon age cycle.

  As a result, the age-displayed timepiece equipped with the display device of the present invention can display an indicator for expressing the age larger than that of the conventional one and can take a larger interval between the indicators, so that the age of the stage is high. In addition to being able to realize the display, the user can more easily understand and visually determine the age of the moon.

  As described above, according to the present invention, a display device that displays information such as a time by using an operating pointer, a symbol graphic written on a display board, and the like, and a scale or a symbol intended for a display unit, In particular, in a display device that displays a continuous amount accompanied by a carry such as time, it is possible to provide a display device that can provide a large amount of movement per unit index and realize high-performance display. Therefore, it is possible to provide a display device that enables real-time display without changing the amount of movement.

[First Embodiment]
Hereinafter, an electronic timepiece 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
In the first embodiment, the present invention is applied to a timepiece with a chronograph function.

The first embodiment shows the basic embodiment of the present invention.
FIG. 1 is a schematic diagram showing a form of an electronic timepiece 1 according to the first embodiment of the present invention.
FIG. 2 is a diagram showing the form and operation of the 1/10 second display unit 5 of the electronic timepiece 1 according to the first embodiment of the present invention.
FIG. 3 is a chart showing the relationship between the 1/10 second display scale 51 and the number of steps moved by the hands 52 of the electronic timepiece 1 according to the first embodiment of the present invention.

  In the electronic timepiece 1 shown in FIG. 1, reference numerals 21 and 22 are operation members for operating the timepiece, and are used for operation of the chronograph function. Reference numeral 3 denotes a pointer display unit that displays a chronograph time value. The pointer display unit 3 includes a second display pointer 41 that displays the measured chronograph seconds, a chronograph minute display pointer 42 that displays the measured minutes, and a chronograph 1/10 that displays the measured chronograph 1/10 seconds. The second display unit 5 is used.

  Furthermore, the chronograph 1/10 second display unit 5 includes a fan-shaped 1/10 second display scale 51, a 1/10 second display pointer 52 that displays 1/10 seconds measured by moving the fan-shaped display area, and Consists of.

  In addition, since components other than the chronograph 1/10 second display part 5 do not constitute the present invention, the description will be greatly simplified below.

  Further, since a general timepiece step motor is used for driving each hand and a general timepiece IC is used for the control thereof, detailed description of the system configuration is also omitted.

In the chronograph 1/10 second display section 5,
The display unit section is 1/10 second, 1 period is 1 second, and this 1 period is divided into two small periods.
0/10 to 4/10 seconds is the first short period, 5/10 to 9/10 seconds is the second short period,
Fan-shaped display is performed with the first short period as the forward path and the second short period as the return path.

Note that the separation of the first short period and the second short period is an example. For example,
1/10 to 5/10 seconds may be the first short period, and 6/10 to 0/10 seconds may be the second short period (see FIG. 6).

In performing the above display, the 1/10 second display scale 51 is
A forward path indicator group 511 for displaying the first short period;
And a return path indicator group 512 for displaying the second short period.
Further, for “0” and “5” corresponding to switching between the forward path and the return path, a “0” display 513 and a “5” display 514 are separately displayed separately from the forward path index group 511 and the return path index group 512. .
The “0” display 513 may be displayed as a part of the forward path index group 511, and the “5” display 514 may be displayed as a part of the return path index group 512. (See FIG. 6).

  As shown in FIG. 2A, the forward path index group 511 and the backward path index group 512 are alternately arranged with a shift of half the unit interval in the traveling direction of the 1/10 second display pointer 52. For example, “9” of the return path index group 512 is arranged between “1” and “2” of the forward path index group 511. As a result, the 1/10 second display pointer 52 does not indicate the indicators of the forward route indicator group 511 and the backward route indicator group 512 at the same time, so that the user does not mistake the forward route and the backward route.

  It should be noted that the amount of deviation between the two indicators does not have to be half of the unit interval, and may be a non-natural number (a positive number having a decimal point) times the unit interval at a level that does not misidentify the forward path and the return path. However, the amount of misalignment that is half of the unit section is most visible and easy to arrange.

  Further, the outward path index group 511 and the backward path index group 512 may have a difference in appearance by font or color. As a result, the difference between the forward path and the return path becomes clearer.

  Further, a graphic indicating the traveling direction of the 1/10 second display pointer 52 may be provided to the forward path index group 511 and the backward path index group 512. In FIG. 2A, the forward path symbol 5111 and the backward path symbol 5121 in the shape of arrows correspond thereto. As a result, the traveling direction of the forward path and the return path becomes clearer.

  Further, the “0” display 513 arranged at the start point and the “5” display 514 arranged at the end point are larger than the other scales.

  This makes it clear that both indicators are turning points. In addition to the size, a difference in appearance such as color and font may be added.

FIG. 3 is a diagram showing the arrangement of the chronograph 1/10 second display scale 51 and the operation of the 1/10 second display pointer 52 by the number of steps of the 1/10 second display pointer 52.
The number of steps is set so that the starting point is 0 and increases clockwise.

  The total number of steps used for the display of 0/10 to 9/10 seconds is the same 9 steps as the prior art shown in FIG. 4, but between “0” and “1” and between “5” and “6” One step and the other sections are arranged to have two steps, and the deviation amount between the forward path index group 511 and the backward path index group 512 is half (1 step) of the minimum section (2 steps).

  In the forward path and the return path, the 1 / 10-second indicator pointer 52 has the same hand movement form except for the traveling direction.

  According to the above arrangement, it is only necessary to move two steps in 1/10 seconds, and the step motor only needs to be able to move at 20 Hz in both forward and reverse directions. Unlike the prior art shown in FIG. Even in this case, the 1/10 second display can be displayed in real time.

  Further, since the interval between the indexes can be made wider than that in the prior art shown in FIG. 4, the indexes themselves can be increased, and the visibility can be improved.

  FIG. 2A is a diagram when the 1/10 second display unit 5 of the present embodiment indicates 2/10 seconds. FIG. 2B is a diagram when the 1/10 second display unit 5 of the present embodiment indicates 7/10 seconds.

  As apparent from FIGS. 2A, 2B, and 3, even if the 1/10 second display pointer 52 displays any scale of the 1/10 second display scale 51, It is designed not to cause misunderstandings.

  Further, by reading an indicator associated with the forward path symbol 5111 or the backward path symbol 5121 according to the movement direction of the pointer, the scale can be read more easily.

[Operation of Electronic Timepiece 1 in First Embodiment]
Next, the operation of the electronic timepiece 1 in the present embodiment will be described with reference to FIGS.

  When the timekeeping operation of the electronic timepiece 1 is started by the operation of the operation member 22, the 1/10 second display pointer 52 indicating “0” of the 1/10 second display scale 51 is rotated clockwise (outward direction). Rotate.

  The rotation is 1 / 10th of a scale, and the value of the 1/10 second display scale 51 indicated by the 1/10 second display pointer 52 is 1/10 second measured by the electronic timepiece 1. Always synchronized with.

  As shown in FIGS. 2C and 3, the 1/10 second display pointer 52 indicating “5” of the 1/10 second display scale 51 starts to rotate counterclockwise (return direction) this time.

  The rotation is also 1 scale in 1/10 seconds as in the forward direction, and the value of the 1/10 second display scale 51 indicated by the 1/10 second display pointer 52 is measured by the electronic timepiece 1. Always synchronized with 1/10 second.

  As shown in FIGS. 2D and 3, the 1/10 second display pointer 52 indicating “0” on the 1/10 second display scale 51 starts to rotate clockwise (forward direction) again.

  At this time, a carry occurs, and the second indicator pointer 41 rotates about 6 °, thereby displaying the counted second. When the second display hand 41 rotates once, a carry to the minute occurs, and the minute display hand 42 rotates about 6 °, thereby displaying the counted time.

[Effect of the first embodiment]
With the configuration as described above, the interval between the scales in the display area can be increased compared to the conventional 1/10 second display as shown in FIG. 4A, and the visibility can be improved. Since a large amount of movement per unit scale can be obtained, a display with high performance can be realized.

  In addition, by arranging the scales alternately, it is possible to read the scale accurately without misidentifying the index (scale) indicated on the forward path and the return path. And since the numerical font etc. which comprise a scale can be arrange | positioned largely, the electronic timepiece 1 with higher design property can be provided.

  Further, as shown in FIG. 4B, when the scale moves from the scale “9” to the scale “0”, the operation at the time of carry of the conventional 1/10 second display that requires a large amount of pointer movement for a short time is required. On the other hand, as shown in FIG. 3, it is possible to provide the electronic timepiece 1 that enables real-time display of 1/10 second without performing a high-speed pointer operation in a short time.

[First Modification of First Embodiment]
In the 1/10 second display portion 5 of the electronic timepiece 1 in the present embodiment, the 1/10 second display pointer 52
1 has a general bar-shaped pointer shape, but as shown in FIG. 5, a 1/10 second display scale 51 that clearly shows the shape of the 1/10 second display pointer 52 in the forward direction and the backward direction is clear. By doing so, the electronic timepiece 1 with improved visibility can be provided.

  In FIG. 5, the 1/10 second indicator pointer 52 indicates the forward direction indicating unit 521 for indicating the scale “1” to “4” in the going direction, and the return path for indicating the scale “6” to “9” in the return direction. The display unit 522 is configured.

  In this modification, the scales “0” and “5” are arranged larger than the other scales, so that the entire 1/10 second display pointer 52 is designated.

  Note that the operation of the electronic timepiece 1 in the present modification is the same as the operation of the electronic timepiece 1 in the first embodiment, and thus the description thereof is omitted here.

  FIG. 5A is a diagram when the 1/10 second display pointer 52 of the present modification indicates 2/10 seconds. FIG. 5B is a diagram when the 1/10 second display pointer 52 of the present modification indicates 7/10 seconds.

  With such a configuration, the 1/10 second display scale 51 indicated by the 1/10 second display pointer 52 becomes clear, and the electronic timepiece 1 with improved visibility can be provided.

  Of course, this first modification is not limited to the embodiment shown in FIG. For example, the forward path instruction unit 521 may have a shape surrounding the index (scale) similarly to the return path display unit 522, and the forward path instruction unit 521 may have a square shape or a triangular shape. In this way, it is easier to understand what is instructing the outbound or inbound journey. However, when the moment load of the 1/10 second indicating hand 52 is taken into consideration, the shape of FIG. 5 is preferable.

[Second Modification of First Embodiment]
Further, in the 1/10 second display portion 5 of the electronic timepiece 1 in the present embodiment, the 1/10 second display pointer 52 has a general bar-shaped pointer shape. However, as shown in FIG. The bottom may be indicated by the rotation of a display disk with instruction symbols.

  In FIG. 6, a 1/10 second display scale 51 is arranged around a fan-shaped 1/10 second display window 31, and a 1/10 second indication symbol 531 is provided below the 1/10 second display window 31. A / 10 second display disk 53 is rotatably arranged by a driving means (not shown) such as a step motor.

  In FIG. 6, unlike FIG. 2 and FIG. 5, 1/10 to 5/10 seconds is the first short period, and 6/10 to 0/10 seconds is the second short period, and “5” indicating both ends. And “0” constitute the forward path index group 511 and the backward path index group 512, respectively.

  Although the forms are different from those in FIGS. 2 and 5, numbers 511 and 512 are used as they are for easy understanding of the correspondence.

  In addition, the operation of the electronic timepiece 1 in this modification is the same as the operation of the electronic timepiece 1 in the first embodiment except that the hands are display disks.

  The 1/10 second instruction symbol 531 indicates a downward outward direction instruction symbol 5311 for indicating the scales “1” to “5” as the outward path index group 511, and indicates “0” from the return path index group 512 for the scales “6”. And an upward return direction instruction symbol 5312.

  FIG. 6A is a diagram when the 1/10 second display pointer 52 of the present modification indicates 2/10 seconds. FIG. 6B is a diagram when the 1/10 second display pointer 52 of the present modification indicates 7/10 seconds.

  In addition, the downward outward direction instruction symbol 5311 and the upward backward direction instruction symbol 5312 in FIG. 6 have the same shape except for the direction, but like the 1/10 second display pointer 52 in FIG. 5, the color, size, shape, etc. You may give a difference in appearance.

  By providing such a configuration, it is possible to provide an electronic timepiece 1 with improved design, in which a 1/10 second timekeeping value is displayed with high visibility by a display disk provided with an instruction symbol that rotates under a display window. Can do.

[Second Embodiment]
Next, an electronic timepiece 1 according to a second embodiment of the present invention will be described with reference to FIGS.
In the second embodiment, the present invention is applied to date display. Therefore, the unit interval is one day, and one cycle is 31 days. Further, the display form is not a fan display but a straight-ahead display.

As shown in the schematic diagram of FIG. 7, the electronic timepiece 1 according to the second embodiment includes an operation member 2 for correcting time and a pointer display unit 3 for displaying time. Rotating within the circular display area of the pointer display section 3, the time display pointer 6 displays the current hour and minute, and the date display section 7 has a rectangular display area for displaying the date.
The date display unit 7 includes a date display scale 71 and a date display indicator 72.

  Further, the date display scale 71 provided in the electronic timepiece 1 in the present embodiment is a scale from “1” to “16” from the end (start point) to the other end (end point) of the display area, as shown in FIG. And a scale from “17” to “31” from the end point to the start point. That is, the 1st to 16th days correspond to the first short cycle, and the 17th to 31st days correspond to the second short cycle.

  Further, the scale in the forward direction is arranged integrally with the forward path index group 711 which is a symbol indicating the direction of the forward path, and the scale in the return direction is a return path index group 712 which is a symbol indicating the direction of the return direction. They are arranged together.

  Further, the date display scale 71 is arranged so that the scale in the going direction (upward) and the scale in the return direction (downward) are alternately arranged.

FIG. 8A is a diagram when the date display unit 7 of the present embodiment indicates 10 days.
As is clear from FIG. 8A, no matter which scale of the date display scale 71 is displayed by the date display indicator 72, misidentification with other scales is prevented.

  Further, the scale can be read more easily by reading the scale associated with the forward path index 711 or the backward path index 712 according to the movement direction of the pointer.

[Operation of Electronic Timepiece 1 in Second Embodiment]
Next, the operation of the electronic timepiece 1 in the present embodiment will be described with reference to FIG.

  When the date displayed on the electronic timepiece 1 is updated due to the elapsed time or the operation of the operation member 2, the date display pointer 72 operates by one scale.

  At this time, if the date before the update is between the 1st and the 15th, the date display indicator 72 operates in the upward direction (the going direction) as shown in FIG.

  When the date before the update is between the 16th and 31st, the date display indicator 72 operates downward (return direction) as shown in FIG. 8B.

  The operation of the time display hand 6 is the same as that of a general analog timepiece that displays the time using the long and short hands, and therefore the description thereof is omitted here.

[Effect of the second embodiment]
With the configuration as described above, the scale interval in the display area can be widened with respect to the conventional date display, the visibility can be improved, and the amount of movement per unit scale can be increased. Therefore, a display with high performance can be realized.

  Further, by arranging the scales alternately, it is possible to arrange large numbers of fonts constituting the scales, so that the electronic timepiece 1 with higher design can be provided.

[Third Embodiment]
Next, an electronic timepiece 1 according to a third embodiment of the present invention will be described with reference to FIGS.
In the third embodiment, the present invention is applied to age display. Therefore, one cycle is 29.5 days.

As shown in the schematic diagram of FIG. 9, the electronic timepiece 1 according to the third embodiment includes an operation member 2 for correcting the time and a pointer display unit 3 for displaying the time. The pointer display unit 3 includes a time display pointer 6 that rotates within a circular display area of the pointer display unit 3 and displays the current hour and minute, and a fan-shaped month display unit 8.
The moon age display unit 8 includes a moon age symbol display 81 and a moon age display indicator 82.

  Further, as shown in FIG. 10, the age symbol display 81 included in the electronic timepiece 1 in the present embodiment has a new moon (month age 0) at the end (start point) of the display area and a full moon (month age 15) at the other end (end point). As shown, the age symbols corresponding to the ages 1 to 14 including the moon of the upper chord from the start point to the end point, and the ages symbols corresponding to the ages 16 to 29 including the moon of the lower chord from the end point to the start point are arranged.

In addition, the forward age direction age symbol is integrally arranged with the forward direction indicator group 811 which is a symbol indicating the direction of the forward direction, and the return age direction age symbol is a return direction indicator group which is a symbol indicating the direction of the return direction. 812 is integrated with 812.
Further, the age symbols other than the new moon and the full moon are arranged so that the symbols in the going direction (clockwise) and the symbols in the returning direction (counterclockwise) are alternately arranged.

  FIG. 10A is a diagram when the age display unit of the present embodiment indicates a full moon (month age 15). FIG. 10 (B) is a diagram showing the same first quarter moon (month age 7.5). FIG. 10 (C) is a diagram showing the same month of the lower chord (month age 22.5).

  As apparent from FIGS. 10A to 10C, no matter what symbol of the age symbol display 81 is displayed on the age indication pointer 82, it is not misidentified as another symbol. .

  Further, the scale can be read more easily by reading the scale associated with the forward path index 811 or the backward path index 812 according to the movement direction of the pointer.

[Operation of Electronic Timepiece 1 in Third Embodiment]
Next, the operation of the electronic timepiece 1 in the present embodiment will be described with reference to FIG.

  When the age displayed on the electronic timepiece 1 is updated by the elapsed time or the operation of the operation member 2, the age display indicator 82 operates by one symbol.

  At this time, when the age before update is between 0 and 14, the age display indicator 82 rotates clockwise (in the forward direction). When the age before update is between 16 and 29, the age indication pointer 82 rotates counterclockwise (return direction).

  The operation of the time display hand 6 is the same as that of a general analog timepiece that displays the time using the long and short hands, and therefore the description thereof is omitted here.

[Effect of the third embodiment]
By adopting the configuration as described above, the interval of the age display symbol 81 in the display area can be increased with respect to the conventional age display of the pointer type, so that the visibility can be improved and the movement amount per unit scale Therefore, display with high performance can be realized.

  In addition, in the case of a new moon (month age 0) and a full moon (month age 15), since the moon age display pointer 82 indicates the end of the display area, it becomes possible to display the moon age more easily.
