Description

clock

The present invention relates to a timepiece, and more particularly, to a pointer-type timepiece that can display time accurately to the minute unit without using a minute hand. The present invention is applicable not only to so-called analog timepieces with mechanical movement, such as wristwatches, table clocks, wall clocks, but also to all pointer-type timepieces including timepieces driven by an electronic circuit having a graphical display unit. Is possible.

Conventionally, pointer-type watches are known. In general, a pointer-type timepiece has a dial, an hour hand, and a minute hand (see, for example, Patent Document 1). Each pointer rotates on the dial to display the hour and minute. On the outer periphery of the dial, numbers 1 to 12 are displayed at regular intervals “every hour”, and four scales are engraved “every minute” between each number. Depending on which number the hour hand points to and what number or scale the minute hand points to, what time the current time is (hereinafter referred to as “hour time”) how many minutes (hereinafter “minute time”) So that you can know if

In addition, a timepiece having a cylindrical side face as a dial has also been proposed (see, for example, Patent Document 2). According to this configuration, numerals are displayed on the cylindrical side face, and the cylinder has its center axis as the center of rotation. By rotating, the current time can be read. In Patent Document 2, the hour hand and the minute hand are not disclosed, but the short hand cylinder 3, the long hand cylinder 2 and the index 7 substantially function as the hour hand and the minute hand.

Japanese Patent Application Laid-Open No. 5-172954 Utility Model Registration No. 3078334

However, the device described in Patent Document 1 uses a minute hand to display the minute time. Also in Patent Document 2, the long hand cylinder 2 and the index 7 corresponding to the minute hand are used to display the minute time. Therefore, it is necessary to separately construct a mechanism and a structure for driving and transmitting in order to display the minute and time, resulting in an increase in cost, an increase in the number of parts, and a complicated assembly work.

Also, the time and time must be read from the position of the hour hand, and the minute and time must be read from the position of the minute hand. In order to read the exact time up to the minute unit, both times indicated at different positions must be read. Need to read. In particular, in the one disclosed in Patent Document 2, a long hand cylinder 2 indicating time and time and a short hand cylinder 3 indicating minute time are configured in two upper and lower stages, and it is necessary to read the positions indicated by different indexes 7. .

Therefore, there is a need for a proposal relating to a clock that can accurately display the minute and time without separately configuring a structure for displaying the minute and time. In addition, it is even more preferable if such a watch gives the user a new interest that has never been seen before.

The present invention has been made in view of the above circumstances, and provides a novel and useful pointer-type timepiece that can accurately display the time up to the minute unit using only the hour hand without using the minute hand or the like. Is an exemplary problem.

In order to solve the above-described problem, a timepiece as an exemplary aspect of the present invention includes an hour hand and a dial that extend from the first root portion to the first tip portion, and includes an hour hand and a dial. A dial type timepiece that displays time by relative movement, and a plurality of dials are arranged at equal intervals so as to extend long from the side close to the first base portion to the side close to the first tip portion and intersect the hour hand The crossing position of the hour hand and the auxiliary display portion is changed from the first root portion side to the first tip portion side or from the first tip portion side to the first root portion side as time passes. And configured to move.

“Hour hand” means “short hand” in a watch. “Relative movement between the clock and the dial” means that one or both of them moves, and does not specify which one moves. The dial may further include “time display units” arranged at equal intervals corresponding to the plurality of auxiliary display units. The “time display part” is typically a number from 1 to 12 or a number from 1 to 24, and represents a time and time corresponding to 12 hours or 24 hours. Of course, it is not limited to numbers, and may be marks, symbols, and characters, or some may be numbers and some may be marks. The “auxiliary display” is typically a scale line displayed on the dial. The auxiliary display section may be a zigzag line or a curved line.

Since the hour hand and the auxiliary display portion intersect and the crossing position moves along the extending direction of the hour hand with the passage of time, the minute time can be read easily and accurately by the crossing position. Since the moving distance of the intersection position is long, the resolution of the minute time display can be increased, and an accurate minute time display can be realized. Minute time display can be realized more accurately by using a scale on the auxiliary display unit or an auxiliary scale provided on the hour hand.

∙ Since a minute hand or the like is not required for displaying the minute time, it is possible to reduce costs, reduce the number of parts, and reduce assembly man-hours. Since there is no drive structure such as a minute hand, the structure of the entire timepiece can be simplified, and the reliability can be improved (the failure rate can be reduced and the life of the apparatus can be improved).

In addition, since both the hour and minute time can be accurately read only by the position of the hour hand, it is possible to accurately and quickly grasp the time. There is no need to read both times indicated at different positions by the hour and minute hands. Of course, a world clock can be realized by arranging a plurality of hour hands instead of the hour and minute hands. In this case, the plurality of hour hands are arranged to correspond to different times in different regions (countries).

The auxiliary display portion is formed to extend from the second root portion located on the first root portion side between the first root portion and the first tip portion toward the second tip portion located near the time display portion. And the second tip portion of the auxiliary display unit adjacent to the specific auxiliary display unit and the hour hand start crossing immediately after the second root portion of the specific auxiliary display unit and the hour hand have finished crossing, or The second root portion of the auxiliary display unit adjacent to the specific auxiliary display unit and the hour hand may start crossing immediately after the second tip portion of the specific auxiliary display unit and the hour hand finish the crossing.

Since the auxiliary display part is extended and formed, the moving distance of the crossing position where the two cross each other can be further increased. Therefore, the minute time can be displayed more accurately. In addition, it is not restricted to when both an hour hand and an auxiliary | assistant display part are a straight line, either one may be a curve and the other may be a straight line, and both may be a curve. A new and interesting design can give the user a new interest.

The relative movement may be realized by the dial being a plane and the hour hand rotating on the dial about the central axis in the vicinity of the first root portion. According to this configuration, a wristwatch, a table clock, a wall clock, or the like can be suitably realized.

A dial is formed on a surface extending in a direction along a closed curve defined in a predetermined plane and a direction along a normal of the predetermined plane, and an hour hand is disposed in the vicinity of the dial and is substantially normal. The relative movement may be realized by extending in the direction and rotating the dial circularly along the closed curve, or by moving the hour hand in the direction along the closed curve.

According to this configuration, the dial is formed on a surface extending in the normal direction of the closed curve (hereinafter referred to as a closed curved surface). The closed curved surface referred to here may typically be a cylindrical outer peripheral surface, or may be a belt surface of an endless belt-like member stretched around the outer periphery of a plurality of rotating cylinders. When the closed curved surface is a cylindrical outer peripheral surface, the closed curve is of course circular. When the closed curved surface is the belt surface of the endless belt-like member, the closed curve is the periphery of the endless belt-like member.

As described above, when a dial is formed on a closed curved surface and a plurality of hour hands are arranged, for example, a world clock can be suitably realized. That is, by arranging a plurality of hour hands corresponding to a plurality of regions (countries) at a plurality of positions on a closed curved surface, a world clock with a simple structure and easy to read time can be realized.

In particular, the one disclosed in Patent Document 2 must read the time and minute times indicated by different indexes at different positions, whereas according to the present invention, the time is indicated only by a fixed hour hand. Both time and minute time can be read accurately and quickly. Therefore, the present invention is particularly suitable as a world clock that displays a plurality of times at a plurality of positions.

It should be noted that the timepiece according to the present invention may be realized by circulating and rotating the dial along a closed curve. The circulation rotation along the closed curve is, for example, a rotational movement around the center axis of the cylinder when the dial is a cylindrical outer peripheral surface. In addition, when the dial is a belt surface of an endless belt-like member spanned by a plurality of rotating cylinders, the endless belt-like member is circulated and moved by rotating each cylinder around its central axis. In other words, this circular movement can be called a belt conveyor-like movement or a caterpillar-like movement.

Further, the timepiece according to the present invention may be realized by moving the hour hand along the closed curve in the vicinity of the dial instead of moving the dial. In this case, one hour hand may make one round along the closed curve in 12 hours or 24 hours.

It should be noted that the direction in which the hour hand extends is substantially the normal direction includes, for example, a case where the hour hand extends in parallel along the normal line and a case where the hour hand extends in the normal direction with a slight inclination with respect to the normal line. For example, the hour hand extends parallel to the normal and the auxiliary display on the dial extends slightly inclined with respect to the normal, or the hour hand extends slightly inclined with respect to the normal and the auxiliary display The present invention can be realized by a configuration in which the hour hand and the auxiliary display portion extend slightly inclined at different inclination angles with respect to the normal line.

Further problems or other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

According to the present invention, the minute time can be accurately displayed without separately configuring a structure for displaying the minute time. In addition, a new interest can be given to the user. Since the timepiece structure can be simplified, it is possible to reduce the cost, the number of parts, and the number of assembly steps. The reliability of the watch can also be improved.

[Embodiment 1]
Hereinafter, a timepiece according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing an outline of the overall configuration of a timepiece W according to Embodiment 1 of the present invention. This timepiece W is configured as a wall clock. However, the present invention can be applied to all types of pointer-type clocks such as wristwatches, table clocks, alarm clocks, and wall clocks.

The watch W has a transparent plate 4 on the front side of the housing 2, and a dial 6 is disposed inside the transparent plate 4. The transparent plate 4 is for making the dial 6 visible from the outside, and glass, a transparent resin such as acrylic or polycarbonate, a transparent film, or the like can be applied.

The watch W has an hour hand 8 on the dial 6 but does not have a minute hand. The timepiece W has driving means (not shown) for rotating the hour hand 8 therein. The driving means rotates the hour hand 8 so as to make one round in 12 hours with the central axis 10 in the vicinity of the root portion (first root portion) 8a as the rotation center. Since a well-known one can be applied to the configuration of the driving means, description thereof is omitted.

FIG. 2 is a front view of the dial 6 as viewed from the front, and FIG. 3 is a partially enlarged view schematically showing the hour hand 8 with a line segment. The dial 6 is formed on the surface of a substantially circular flat plate member, and numbers (time display portions) A of “1” to “12” are printed every 30 ° along the outer periphery thereof. . A scale corresponding to the 1 minute interval is not engraved between adjacent numbers. On the other hand, twelve auxiliary lines (auxiliary display portions) B are printed on the dial 6 corresponding to the numbers A, respectively. The auxiliary line B is formed to extend from the root portion (second root portion) Ba located near the root portion 8a of the hour hand 8 toward the tip portion (second tip portion) Bb located near the numeral A. Are arranged at equal intervals. In addition to the number A, a simple line segment display or some mark display can be applied as the time display unit. In some cases, a small glass or jewelry is arranged to form the time display unit. Is also possible. Of course, the time display unit is not necessarily an essential configuration. The tip Bb of the auxiliary line B may function as a time display unit.

The hour hand 8 is a pointer that makes one turn over the dial 6 over 12 hours, and is rotated clockwise around the central axis 10 by a driving means (not shown). The hour hand 8 is configured to extend from the root portion 8a to the distal end portion (first distal end portion) 8b, and the distal end portion 8b circulates and rotates in the vicinity of the numeral A. In the first embodiment, the hour hand 8 extends linearly and radially from the central axis 10 from the root portion 8a toward the tip portion 8b.

In the first embodiment, the auxiliary line B extends radially and linearly from the root portion Ba toward the tip end portion Bb. Here, for example, taking numeral A ″ 1 ″ and numeral A ″ 2 ″ as an example, the vicinity of the tip 8b of the hour hand 8 and the tip Bb of the auxiliary line B corresponding to the number A ″ 1 ″ intersect. Immediately after finishing (intersection position P1) (next unit time, for example, 1 minute later), the vicinity of the root portion 8a of the hour hand 8 and the root portion Ba of the auxiliary line B corresponding to the numeral A "2" intersect. An auxiliary line B is formed so as to start (intersection position P2). That is, the auxiliary line B extends in a radial direction toward the numeral A from a position slightly shifted from the central axis 10, but not in a radial direction from the central axis 10 toward the numeral A, although it is radial.

As a result, the hour hand 8 and the auxiliary line B always intersect each other, and the intersection position P2 moves from the root portion 8a side to the distal end portion 8b side as time passes. . And the intersection position P2 will move the long distance from the root part Ba of the auxiliary line B to the front-end | tip part Bb in 1 hour from 1 o'clock to 2 o'clock. If the minute time scale is displayed from the root portion Ba to the tip portion Bb, the accurate minute time can be displayed only by the hour hand 8 without requiring the minute hand. Of course, the minute time may be displayed by displaying the minute time scale (auxiliary scale) on the hour hand 8 side.

For example, FIG. 4 is an example in which a minute time scale 8c is displayed on the hour hand 8 side. The hour hand 8 has a substantially rectangular shape when viewed from the front, and has a central portion as a punched portion 8d so that the dial 6 and the auxiliary line B can be visually recognized through the punched portion 8d. In the punched portion 8d, a plurality of minute time scales 8c are formed in a ladder shape along the longitudinal direction of the hour hand 8 (11 in the first embodiment). In FIG. 4, eleven minute time scales 8c corresponding to the lapse of minute time every 5 minutes (the tip 8b of the hour hand 8 corresponds to the twelfth minute time scale 8c) are simply displayed. Actually, however, 59 minute time scales 8c corresponding to the passage of minute time every minute may be displayed on the hour hand 8.

In the first embodiment, since both the hour hand 8 and the auxiliary line B are both straight lines, the intervals between the minute time scales 8c are not equal, but from the side close to the root portion 8a to the tip portion 8b. The distance gradually increases toward the near side. As will be described later, at least one of the hour hand 8 and the auxiliary line B needs to be curved in order to make the interval between the minute time scales 8c equal.

[Modification 1]
FIG. 5 is a front view of the dial 61 of the watch W1 according to the first modification of the present invention as seen from the front. Also in FIG. 5, the hour hand 8 is schematically shown by a line segment. In this timepiece W1, the auxiliary line B is curved so that the intersection of the auxiliary line B with the hour hand changes equidistantly on the hour hand 8 with the passage of time. Is formed in a spiral shape.

When the time is exactly 1 o'clock, the tip Bb of the auxiliary line B corresponding to the numeral A "1" and the vicinity of the tip 8b of the hour hand 8 intersect at the intersection position P1. Thereafter, when the time elapses, the hour hand 8 rotates clockwise toward the numeral A "2", and the crossing position P1 moves from the distal end portion 8b side to the root portion 8a side.

At 1:59, the base portion Ba of the auxiliary line B corresponding to the numeral A “1” and the vicinity of the base portion 8 a of the hour hand 8 intersect each other. At about 2 o'clock, the tip Bb of the auxiliary line B corresponding to the numeral A "2" and the vicinity of the tip 8b of the hour hand 8 intersect at the intersection position P2.

Also in the timepiece W1 according to the modification 1, the minute time can be accurately grasped by the intersection position of the auxiliary line B and the hour hand 8. In addition, the auxiliary line B is formed in a curved line, which can give the user an unprecedented new interest.

In addition, by giving the curve shape of the auxiliary line B based on the following formula, the intersection with the hour hand 8 can be configured to change equidistantly on the hour hand 8 with the passage of time. Thereby, the interval between the minute time scales 8c formed on the hour hand 8 can be made equal.

<Equation 1>
x = (R + Ct) * cos (at)
y = (R + Ct) * sin (at)
Where R: innermost radius of intersection point C: radial movement distance of intersection point per unit time a: rotation angle of intersection point per unit time t: time x: lateral direction when center axis 10 is the origin (3 o'clock) Direction) coordinates y: longitudinal direction (12 o'clock direction) coordinates when the central axis 10 is the origin For example, in the first embodiment, the innermost radius R of the intersection is the radius from the central axis 10 of the root portion Ba Directional distance. The radial movement distance C of the intersection per unit time is roughly equivalent to the distance from the root 8a to the tip 8b of the hour hand 8, and is the radial distance from the root Ba to the tip Bb of the auxiliary line B. It corresponds roughly. In the first embodiment, since the hour hand 8 makes one round in 12 hours, if the unit time is 1 minute, the rotation angle a of the intersection per unit time is 360 ° / (12 * 60) = 0.5 °.

For example, assuming a wall clock having a diameter of about 300 mm, if R = 30 mm, C = {(300/2) -30} / 60 = 2 mm, and the shape of the auxiliary line B corresponding to the numeral A "2" Is as shown in FIG. When the shape of the auxiliary line B shown in FIG. 6 is rotated by 30 ° about the origin, auxiliary lines B corresponding to other numbers A can be formed. At this time, since the radial movement distance C of the intersection per unit time is 2 mm, the interval between the minute time scales 8c formed on the hour hand 8 is 2 mm. Note that the present invention can be applied to the curved line shape of the auxiliary line B even if the direction of the convex direction of the curved line shape calculated based on <Equation 1> is reversed. In this case, in the above <Equation 1>, <Equation 2>
x = (R + Ct) * cos (at)
y =-(R + Ct) * sin (at)
Like this, the sign of y may be reversed.

[Modification 2]
FIG. 7 is a front view of the dial 62 of the timepiece W2 according to the second modification of the present invention as seen from the front. Also in FIG. 7, the hour hand 8 is schematically shown by a line segment. In this timepiece W2, the hour hand 8 is curved so that the intersection with the auxiliary line changes equidistantly on the auxiliary line as time passes from the base part 8a to the tip part 8b. A straight line is formed from Ba to the tip Bb. Other configurations are the same as those of the first modification, and thus the description thereof is omitted. Also in the timepiece W2 according to the second modification, the minute time can be accurately grasped by the intersection of the hour hand 8 and the auxiliary line B. Further, the rotational position of the hour hand 8 with the passage of time moves the crossing position with the auxiliary line B from the distal end portion 8b side to the root portion 8a side.

In the second modification, the curved shape of the hour hand 8 is a shape calculated based on the above <Equation 1> or <Equation 2>.

[Modification 3]
FIG. 8 is a partially enlarged view of the dial 63 of the timepiece W3 according to Modification 3 of the present invention as seen from the front. Also in FIG. 8, the hour hand 8 is schematically shown by a line segment. The timepiece W3 is similar to the timepiece W1 according to the first modification in that twelve curved auxiliary lines B are spirally formed from the vicinity of the central axis 10, but the auxiliary line B is continuous. Instead of a regular line segment, it is formed by an array of a plurality of dots d arranged at equal intervals in time. In addition, a part of dot is abbreviate | omitted and shown with the dashed-dotted line.

In other words, in the first modification, the minute time scale 8c corresponding to the minute time is arranged on the hour hand 8 at equal intervals, but in this second modification, the dots d corresponding to the minute time scale are as a whole. An auxiliary line B is configured. The shape of the dot d is calculated based on the above <Equation 1> or <Equation 2>, and the interval between the dots d is “the distance dp in the radial direction from the central axis 10 between the adjacent dots d is equal”. It is said that. Further, it is equivalent to “the crossing angle da at the central axis 10 between the straight lines connecting the adjacent dots d and the central axis 10 is an equal angle”. This is also a concept that can be applied to the case where the minute time scale 8c is formed on the hour hand 8 in the second modification.

Since the minute time is displayed by the intersection of the dot d and the hour hand 8, visibility is further improved compared to the case of the intersection of the continuous curve auxiliary line and the straight hour hand 8, and the minute time is easily grasped. Further, if the number of dots d on one auxiliary line B is set to 60 so as to correspond to an interval of 1 minute, it is easier to grasp the minute time. Other configurations are the same as those of the first modification, and thus the description thereof is omitted.

[Modification 4]
FIG. 9 is a front view of a dial 64 of a timepiece W4 according to Modification 4 of the present invention as seen from the front. Also in FIG. 9, the hour hand 8 is schematically shown by a line segment. In the timepiece W4, the auxiliary line B does not extend to the vicinity of the root portion 8a, and is folded at a turning point Bd located slightly on the root portion 8a side from the middle between the root portion 8a and the tip portion 8b of the hour hand 8. Yes. Then, the auxiliary line B corresponding to the number A "1" is folded from the front end Bb at the turning point Bd and connected to the front end Bb of the auxiliary line B corresponding to the number A "2".

Also in the timepiece W4 according to the modification 4, the minute time can be accurately grasped by the intersection of the hour hand 8 and the auxiliary line B. Further, by the rotational movement of the hour hand 8 over time, the intersection position with the auxiliary line B moves from the tip 8b side to the root portion 8a side or from the root portion 8a side to the tip portion 8b side.

In the fourth modification, the curve shape of the auxiliary line B is a shape calculated based on the above <Equation 1> or <Equation 2>. That is, the auxiliary line B according to the modified example 4 is configured by connecting the curve shape calculated in <Equation 1> and the curve shape calculated in <Equation 2> at the turning point Bd.

[Modification 5A]
FIG. 10A is a front view of a dial 65 of a timepiece W5 according to Modification 5A of the present invention as seen from the front. This clock W5 is configured as a world clock that can simultaneously display the time in a plurality of regions (countries). In the timepiece W5, the dial 65 rotates around the central axis 10 in the X direction in the figure for 24 hours in one turn. The dial 65 is provided with 24 auxiliary lines B, and 8 numbers A corresponding to “3” and “6” are formed.
, “9”, “12”, “15”, “18”, “21”, “24” are formed every three hours.

The dial 65 rotates around the central axis 10 while the hour hand 8 is fixed without rotating. In this timepiece W5, a plurality of hour hands 8 are arranged so as to correspond to each region. For example, the hour hand 81 displays the time in Tokyo, the hour hand 82 displays the time in Stockholm, and the hour hand 83 displays the time in New York. .

[Modification 5B]
FIG. 10B is a front view of a timepiece W8 according to Modification 5B as a variation of Modification 5A of the present invention when viewed from the front. Like the watch W5, this watch W8 is configured as a world clock that can simultaneously display the time in a plurality of regions (countries). In this watch W8, the dial 68 is centered on the central axis 101 in the figure. It rotates once in 24 hours in the X direction. On the

dial

68, 24 auxiliary lines B are formed, and 24 numbers A are arranged correspondingly.

On the outer periphery of the dial 68, the regional ring 21 is arranged in an annular shape. On this regional ring 21, a plurality of regions or countries are displayed in a positional relationship corresponding to each time difference. While the dial 68 rotates around the central axis 101 with time, the

hour hands

86, 87, and 88 can point to any position corresponding to the region or country indicated on the regional ring 21 and can be stationary (non-rotated). It has become.

On the regional ring 21, a scale 9 for daylight saving time is arranged so that the time of the region or country in which daylight saving time is adopted can also be read. For example, the scale 9 for daylight saving time makes it easy to grasp that in New York, it is 3 o'clock in winter time (time in a time other than daylight saving time) and 4 o'clock in daylight saving time. As a result, the daylight saving time of the region or country in which daylight saving time is set can be easily read. For example, in FIG. 10B, the hour hand 86 points to 5:00 pm in “Tokyo”, and at the same time, the hour hand 87 points to 1:00 am in “Los Angels” in summer time (= “Denver” in winter time). At the time, the hour hand 88 points to 9 am in “London” in summer time (= “Paris” in winter time).

FIG. 10C is a side sectional view of the watch W8. The dial 68 is fixed to the shaft 101 of the timepiece movement 9 that rotates once in 24 hours. The

hour hands

86, 87, 88 have a portion close to one end rotatably engaged with the shaft 102 of the timepiece movement 9, and a magnet 111 is attached to the other end. An iron piece 121 is arranged on the back side of the position corresponding to a plurality of regions (countries) of the region ring 21. Since the magnets 111 of the

hour hands

86, 87, 88 are attracted to the iron piece 121 on the rear side of the regional ring 21 from the back side, the

hour hands

86, 87, 88 can be placed in any region (country). Can be fixed in the corresponding position. The regional ring 21 and the timepiece movement 9 are fixed to the frame 131 of the timepiece W8.

The frame 131 is further locked to the substrate 151 via a bearing 141 that can rotate about the shaft 103. The board 151 has a locking hole 161 for hanging on the wall. For example, by inserting a hook, a nail or the like (not shown) fixed to the wall into the locking hole 161, the watch W8 is engaged with the wall. It can be stopped. The watch W8 locked to the hook or the like by the locking hole 161 can be used with the position of an arbitrary region (country) on the regional ring 21 positioned right above.

[Modification 5C]
10D and 10E are front views of a timepiece W9 according to Modification 5C of the present invention as seen from the front. FIG. 10D and FIG. 10E show the same time, but FIG. 10E displays daylight saving time in regions and countries that adopt the daylight saving time system, and FIG. it's shown.

This clock W8 is configured as a world clock that can display the time in a plurality of regions (countries) at the same time as the clocks W5 and W8 described above. In this timepiece W9, the dial 69 rotates around the central axis 103 in the X direction in the figure for one full 24 hours.

The regional ring 21 has a fixed display portion 22 constituting its inner portion and a display 31 (for example, using an electrophoresis system) constituting its outer portion, and the region and country name are displayed on the display 31. Has been. The display 31 can automatically display an area name and country name at a position corresponding to daylight saving time according to information from a calendar timer (not shown) built in the clock W9. The calendar timer is a timer having a function of measuring not only the time but also what year, month, and day.

Further, the user can select a candidate list of area names and country names to be displayed by an input means (not shown) (in this case, the watch W9 has a database storing not only the input means but also a list of area names and country names. .)), Or any character can be entered. Thus, when a specific region or country is in daylight saving time, for example, the region or country name can be displayed by switching from the winter time display state shown in FIG. 10D to the daylight saving time display state shown in FIG. 10E. This makes it possible to more easily check the time in the region or country where the daylight saving time system is adopted. In addition, since it is possible to freely change the display of the region and country name to the preferred display, it is possible to provide a world clock that is even easier to use.

The display 31 is not limited to the electrophoretic method, and any device that can rewrite display contents by an external electric signal or the like such as a liquid crystal method or an EL method can be used.

The auxiliary line B according to the modified examples 5A to 5C is calculated based on the above <Equation 2>. In this case, since the dial 65 makes one turn in 24 hours, the rotation angle a of the intersection per unit time (1 minute) is a = 360 ° / (24 * 60) = 0.25 °.

[Modification 6]
In the first to fifth modifications, the intersection of the auxiliary line and the hour hand changes equidistantly with the passage of time (the radial distance from the central axis 10 of the intersection increases / decreases at a constant speed with the passage of time. ). However, the curve shape of the auxiliary line B or the hour hand 8 can be determined so that the crossing angle α between the auxiliary line B and the hour hand 8 is constant based on the following <Equation 3>.

<Equation 3>
r = k * e ^bθ
α = arccot (b)
However,
r: distance from the rotation center k: positive constant Here, in order to convert the polar coordinate value (r, θ) to the xy coordinate value,
x = r * cos θ
y = r * sinθ
It becomes. Here, the x-coordinate and y-coordinate are the same as described above.
x: horizontal (3 o'clock direction) coordinates when the central axis 10 is the origin y: vertical (12 o'clock direction) coordinates when the central axis 10 is the origin.

By calculating the curve shape of the auxiliary line B or the hour hand 8 based on this <Equation 3>, the timepiece can be configured such that the crossing angle between the auxiliary line B and the hour hand 8 is always constant. Contributes to the readability of Note that it is possible to appropriately select whether to use the curve shape calculated in the above <Equation 1> or <Equation 2> or the curve shape calculated in <Equation 3>. Depending on the curved shape, the readability in the vicinity of the tip Bb and the readability in the vicinity of the root portion Ba may differ, and the readability may vary depending on the set value of the constant. In particular, the curve shape calculated by <Equation 3> has high visibility in the vicinity of the distal end portion Bb, and is more suitable for a configuration in which the auxiliary line B is folded at the distal end portion Bb and the turning point Bd as in the above-described modification 4. ing.

[Embodiment 2]
FIG. 11 is an external view showing an outline of the overall configuration of a timepiece W6 according to Embodiment 2 of the present invention. The watch W6 has a dial 66 extending in a direction along a circular peripheral edge (closed curve) 13 defined in a predetermined plane H and in a direction along a central axis (normal line of the predetermined plane H) 14. ing. In other words, the dial 66 is formed on the side surface (cylindrical side surface, closed curved surface) 12 of the cylindrical member 11. FIG. 12 is a developed view of the dial 66. FIG.

In the vicinity of the peripheral edge 13 on the

dial

66, 24 numbers A from “1” to “24” are arranged circumferentially at equal intervals. An auxiliary line B is formed corresponding to each number A. The auxiliary line B is inclined along the height direction of the side surface 12, and extends linearly toward the peripheral edge on the opposite side in the development view of FIG. That is, the tip Bb of the auxiliary line B corresponding to the number A ″ 5 ″ is immediately below the number A ″ 5 ″, but the root portion Ba is vertically below the number A ″ 6 ″. The tip Bb of the auxiliary line B corresponding to the number A ″ 6 ″ is immediately below the number A ″ 6 ″, but the root portion Ba is vertically below the number A ″ 7 ″.

The cylindrical member 11 is configured to rotate once around the center axis 14 in 24 hours. On the other hand, the hour hand 8 has a minute time scale 8c in the longitudinal direction, is arranged extending in parallel with the central axis 14 of the side surface 12 (that is, in the vertical direction), and is fixed so as not to rotate. By rotating the dial 66 with respect to the fixed hour hand 8, the relative movement between them and the circulation of the numeral A are realized.

The crossing position P where the hour hand 8 arranged in the vertical direction intersects with the auxiliary line B arranged obliquely moves greatly up and down between the root portion 8a and the tip portion 8b with the passage of time. Yes. The minute time can be accurately grasped by the position of the intersection position P.

In the timepiece W6, if a plurality of hour hands 8 are arranged at different positions, it is possible to realize a world timepiece that displays different times. For example, as shown in FIG. 12, the hour hand 84 can be configured to display the London time and the hour hand 85 can display the Chicago time simultaneously.

Since the hour time and minute time are displayed by one pointer 8, it is possible to immediately grasp the exact time in minutes without moving the viewpoint greatly to different positions. In particular, in the world clock, a plurality of times in a plurality of regions of the world are displayed, and it tends to take time to grasp the time. By applying the present invention, it is possible to quickly grasp the time. Instead of providing a minute time scale on the hour hand 8, a minute time scale may be provided on the auxiliary line B.

In the second embodiment, the case where the dial 66 is rotated has been described. However, the dial 66 is fixed, and the

hour hands

84 and 85 maintain the mutual distance around the periphery of the dial 66. You may be comprised so that circumference rotation may be carried out. In the second embodiment, an example in which the central axis 14 is in the vertical direction has been described. However, the present invention is not limited thereto, and the central axis 14 may be slanted or horizontal depending on the structure or design of the watch W6. Good.

In the timepiece W7, an endless belt-like member 16 is bridged between two roller members 15, and the peripheral edge 17 forms a closed curve composed of two semicircles and two straight lines. A dial 67 is formed on the outer surface extending from the peripheral edge 17 in the direction of the central axis 14.

The dial 67 rotates once in 24 hours as in the second embodiment, and 24 numbers A are displayed near the periphery 17. From each numeral A, 24 auxiliary lines B extend in parallel to the central axis 14 toward the opposite peripheral edge. In the third embodiment, the auxiliary line B is parallel to the central axis 14 and the hour hand 8 disposed in the vicinity of the dial 67 is disposed to be inclined.

The hour hand 8 and the auxiliary line B cross at an angle, and the intersection moves in the direction of the central axis 14 over time. At the next unit time (for example, after one minute) when the root portion Ba of the auxiliary line B and the root portion 8a of the hour hand 8 intersect, the distal end portion Bb of the adjacent auxiliary line B and the distal end portion 8b of the hour hand 8 intersect. It has become.
