Description

The present invention relates to a pointer, a pointer display device, and a timepiece.

Conventionally, in a display device applied to a clock or the like, a pointer is attached to a pointer shaft, and the pointer is rotated by rotating the pointer shaft to display a time and various functions. The device is known.
Further, a so-called combination model in which the pointer display device also includes a digital display unit including a liquid crystal panel or the like is widely used.

However, when the pointer display device is a combination model, the pointer and the liquid crystal panel or the like may overlap depending on the position of the pointer that moves in response to a change in time or the like, and the pointer may hinder the visibility of the liquid crystal panel or the like. ..
In addition, in the case of a solar power generation model in which the pointer display device is a solar power generation model in which the solar panel that generates power by irradiating light is located behind the pointer in the direction of incidence of light from the outside, the pointer overlaps with the solar panel. The light receiving area of the solar panel becomes narrow, and the amount of power generation may decrease. Further, when trying to secure the amount of power generation, there is a problem that the area of the decorative portion such as printing applied to the surface of the dial is restricted by that amount, which impairs the design.

In this regard, for example, Patent Document 1 includes a pointer and a light source formed of a synthetic resin material such as acrylic having translucency, and a light guide plate that guides illumination light from the light source to the pointer or the like is provided on the back surface of the dial. The configuration to be arranged along the above is disclosed.
If the pointer is made of a translucent material in this way, the visibility of the liquid crystal panel or the like is not impaired even if the pointer and the liquid crystal panel or the like overlap each other.
In addition, even if the pointer overlaps with the solar panel, it does not affect the light reception of the solar panel, and the amount of power generated by the solar panel and the design can not be sacrificed.

Japanese Unexamined Patent Publication No. 2005-037256

However, if the pointer is formed of a translucent material, the visibility of the pointer itself becomes low, so that it is difficult to check the time and various function displays, and there is a problem that the analog display unit does not function sufficiently. ..
On the other hand, if a mechanism for illuminating the pointer or the like is provided as proposed in Patent Document 1 to illuminate the pointer, it becomes necessary to arrange a light source, a light guide plate, or the like, and the configuration of the pointer display device is complicated. As a result, it becomes difficult to reduce the size and weight, and the cost is high.

The present invention has been made in view of the above circumstances, and is a pointer and pointer display device that does not interfere with the display of the display unit that displays by other than the pointer, power generation by the solar panel, etc., and has excellent visibility. And the purpose is to provide a watch.

In order to solve the above problems, the guideline according to the present invention is
A light transmitting part with light transmission and
A visible part made of a material with excellent visibility,
With
The visual recognition portion is characterized in that it is provided at the tip portion and the peripheral portion of the hakama portion.

According to the present invention, there is an effect that the display of the display unit, which is displayed by a guide other than the pointer, and the power generation by the solar panel are not hindered, and excellent visibility can be ensured as the guide itself.

Further, the watch 100 is provided with an operation unit 12 on a side portion or the like of the watch case 1.
In the present embodiment, the operation unit 12 is a push button that performs various operations by electrically connecting the end on the insertion side to the contact on the module 6 (see FIG. 3) side. The operation unit 12 is not limited to the push button. For example, the end portion on the insertion side is connected to the module 6 housed inside the watch case 1, and various operations can be performed by pushing or rotating the operation unit 12. It may be a crown or the like configured to enable.

The opening on the visible side (front side) of the watch case 1 is closed by a windshield member 13 made of transparent glass or the like.
Further, the opening on the side opposite to the visible side (back side) of the watch case 1 is closed by a back cover member (not shown).

As shown in FIG. 1, a dial 15 made of a material that transmits light is arranged inside the watch case 1 on the lower side of the windshield member 13 (the back side of the watch, the lower side in FIG. 2). It is set up.
On the peripheral edge of the dial 15, hour character members 16 that serve as a guide for the time indicated by the pointer 5 (hour hand and minute hand) described later are arranged at substantially equal intervals along the circumferential direction of the dial 15. ..
In the present embodiment, an analog type display unit 3 including a dial 15 and an hour character member 16 and the like and displaying using the pointer 5 is configured.
Further, a part of the dial 15 of the present embodiment is a digital display unit 4 (in FIGS. 1 and 3, digital display units 4a and 4b) which is a display unit composed of a liquid crystal panel or the like and performing a digital display. ) Is fitted and arranged.

The module 6 and the like are housed inside the watch case 1 and below the dial 15 (the back side of the watch, the lower side in FIG. 2).
The module 6 includes a hand movement mechanism that operates the pointer shaft 61 (described later) of the clock 100 and the like to move the pointer 5 in the present embodiment, a power source (battery) that operates the hand movement mechanism, and the like (neither is shown). I'm out.
Further, a solar panel 7 that generates electricity by irradiating light is arranged above the module 6 and below the dial 15, that is, behind the pointer 5 in the incident direction of light from the outside.

Further, a pointer shaft 61 is provided at substantially the center of the module 6 so as to penetrate the solar panel 7 and the dial 15 and project upward.
A pointer 5 is rotatably attached to the upper end of the pointer shaft 61 via a hakama portion 55.
The hakama portion 55 for attaching the pointer 5 to the pointer shaft 33 is made of a metal material such as stainless steel, and the guideline 5 has the hakama portion 55 and the base material 51 integrally formed by insert molding. Is preferable.

In this embodiment, as shown in FIG. 1, a clock 100 including a minute hand 5a and an hour hand 5b is shown as a pointer 5. In addition, when it is simply referred to as "guideline 5" in this embodiment, it is assumed that both the long hand 5a and the short hand 5b are included. Further, in FIGS. 2 to 4, only the long hand 5a is shown as an example as the pointer 5, but the short hand 5b also has the same configuration as the long hand 5a in that the common reference numerals are shown in FIG.
The pointer 5 included in the clock 100 as the pointer display device is not limited to this. For example, the timepiece may be provided with three hands, a second hand, a minute hand, and an hour hand, as the pointer 5, and may be provided with a functional hand or the like indicating various indications in addition to the hand indicating the time.

In the present embodiment, the guideline 5 includes a light transmitting portion 52 having light transmission and a viewing portion 54 made of a material having excellent visibility.
Specifically, as shown in FIGS. 2 to 4, the entire pointer 5 (in FIGS. 2 to 4 exemplifies the long hand 5a which is a pointer) is a transparent resin such as an acrylic resin or a synthetic resin that semi-transmits light. It is composed of a base material 51 made of a light-transmitting material such as transparent or semi-transparent glass, and the portion of the guideline 5 that has not been processed as the base material 51 is the light-transmitting portion. It is 52.
The material forming the base material 51 may be any material having light transmittance, and is not limited to the material exemplified here.

Further, a paint containing a fluorescent substance or a phosphorescent substance is formed on the tip portion of the pointer 5 (that is, the portion that points to the hour-shaped member 16 and the like) and the central portion of the pointer 5 (that is, the periphery of the hakama portion 55 and the like). A visual processing layer 53 coated with is provided. In the present embodiment, the portion provided with the visual recognition processing layer 53 is the visual recognition portion 54.
By providing the visible portion 54 at the tip of the pointer 5 or the like in this way, even when the entire pointer 5 is formed of a light-transmitting base material 51 such as a transparent acrylic resin, the hour-shaped member 16 is indicated. High visibility is ensured in parts such as parts where visibility is particularly required.

In the guideline 5 of the present embodiment, the light transmitting portion 52 is a portion that overlaps with the digital display unit 4 at least during the hand movement operation.
As shown in FIGS. 1 and 3, in the present embodiment, the pointer shaft 61 in the plane direction of the dial 15 is sandwiched between the upper and lower (upper and lower in FIG. 1) two places (that is, the 12 o'clock side and the 6 o'clock side in the analog clock). Digital display units 4 (digital display units 4a, 4b) are arranged on the side), respectively.
Of the pointer 5, the minute hand (minute hand) 5a rotates about the pointer shaft 61 as the center of rotation as shown in FIG. 1, and is a portion between the tip of the minute hand (minute hand) 5a and the peripheral portion of the hull portion 55. Is overlapped with one digital display 4 (lower digital display 4b arranged on the 6 o'clock side in the analog clock in FIG. 1), and the rear end of the minute hand 5a is the other digital display. 4 (in FIG. 1, the upper digital display unit 4a arranged on the 12 o'clock side of the analog clock) overlaps.
Therefore, the long hand (minute hand) 5a has a light transmitting portion 52 at a portion between the tip end portion and the peripheral portion of the hakama portion 55 and at the rear end portion.
Further, among the pointers 5, the short hand (hour hand) 5b has a digital portion between the tip of the short hand (hour hand) 5b and the peripheral portion of the hakama portion 55 when the short hand (hour hand) 5b is rotated around the pointer shaft 61. It overlaps with the display unit 4 (in FIG. 1, the upper digital display unit 4a arranged on the 12 o'clock side of the analog clock). In this state, the rear end portion of the short hand (hour hand) 5b does not overlap with the other digital display unit 4 (lower digital display unit 4b arranged on the 6 o'clock side in the analog clock in FIG. 1).
Therefore, in the short hand (hour hand) 5b, only the portion between the tip portion thereof and the peripheral portion of the hakama portion 55 is the light transmitting portion 52.

Further, in the clock 100 of the present embodiment, the solar panel 7 is arranged within the hand movement range of the pointer 5 and below the pointer 5 (that is, behind the pointer 5 in the incident direction of light from the outside). ..
When the pointer 5 overlaps the solar panel 7, the light is blocked by the pointer 5, the light receiving efficiency is lowered, and the amount of power generation is lowered. In particular, when a wide and large pointer 5 is used in the design of the clock 100, the light receiving efficiency of the solar panel 7 is significantly reduced.
In this regard, by forming a part of the pointer 5 as a light transmitting portion 52 through which light is transmitted as in the present embodiment, the amount of light blocked by the pointer 5 can be suppressed, and the decrease in the amount of power generation can be reduced. it can.

In the present embodiment, the visual recognition processing layer 53 is provided at the tip portion of the pointer 5 (that is, the portion that points to the hour-shaped member 16 and the like) and the central portion of the pointer 5 (that is, the periphery of the hakama portion 55 and the like). Although the example in which the visual recognition portion 54 is formed is shown, the position and range in which the visual recognition portion 54 is provided are not limited to this.
In order to make it easy to confirm which part the pointer 5 points to, it is preferable that the visual recognition unit 54 is provided at least at the tip of the pointer 5, but which other part is used as the visual recognition unit 54 in what range. Whether it is the position of the part where visibility is hindered by overlapping with the pointer 5 such as the digital display unit 4, the position of the solar panel 7, and the solar that should be secured to obtain the required power generation amount. It is appropriately determined in consideration of the area of the power generation area of the panel 7, the design as a pointer display device (clock 100), and the like.

Next, the guideline in the present embodiment and the operation of the clock, which is a guideline display device to which the guideline is applied, will be described.

In the present embodiment, in order to form the pointer 5, the hakama portion 55 is first formed of a metal material such as stainless steel, and the hakama portion 55 is inserted into a mold for forming the base material 51. Then, resin is injected around the hakama portion 55 to integrally form the hakama portion 55, which is a metal part, and the base material 51 molded from the resin.
In the present embodiment, the long hand (minute hand) 5a and the short hand (hour hand) 5b are formed by using a mold according to the shape of each.
Next, the surface of the base material 51 (in the present embodiment, the surface on the visual side) is visually treated by applying various surface treatments such as coating a paint containing a fluorescent substance or a phosphorescent substance, a decoration treatment, and the like. The processed layer 53 is formed.
In the present embodiment, the long hand (minute hand) 5a has a visible processing layer 53 formed on the tip portion and the peripheral portion of the hakama portion 55, and the short hand (hour hand) 5b has the front end portion and the rear end from the periphery of the hakama portion 55. The visual processing layer 53 is formed on the entire portion extending to the portion.
The portion where the visual recognition processing layer 53 is provided becomes the visual recognition portion 54, and the portion where the visual recognition processing layer 53 is not formed (that is, the portion between the tip portion and the peripheral portion of the hakama portion 55 in the short hand (hour hand) 5b). In the minute hand (minute hand) 5a, the portion between the front end portion and the peripheral portion of the hakama portion 55 and the rear end portion) serve as a light transmitting portion 52 that transmits light.
As a result, the pointer 5 (in the present embodiment, the long hand (minute hand) 5a and the short hand (hour hand) 5b) is completed.
Since the guideline 5 of the present embodiment is composed of the base material 51 made of resin or the like, the entire guideline 5 can be made lighter than the case where the guideline is made of metal. For example, when compared in terms of specific gravity, it is 2.7 for aluminum, 1.2 for acrylic, and 2.5 for glass. Therefore, for example, even if the width, length, thickness, etc. of the pointer 5 are increased to make the pointer 5 look heavy, distortion due to its own weight is unlikely to occur, and the needle can be moved with a relatively small force. it can.
Further, since the pointer 5 is formed of a resin or the like, it is easier to mold and process than a metal pointer, and the degree of freedom in design such as the shape of the pointer 5 is improved. For example, the pointer 5 can be made into a unique decorative needle by a cutting (polishing) method. As a decoration method, various methods such as printing, painting, and vapor deposition can be applied.

In order to assemble the watch 100, which is a pointer display device, by incorporating the pointer 5 completed in this manner into the watch case 1, first, a solar panel 7 is arranged on the module 6, and then a digital display unit 4 is further placed on the solar panel 7. The dial 15 in which the above is incorporated is arranged.
As described above, the pointer shaft 61 protrudes from the module 6 toward the visual recognition side, and the solar panel 7 and the dial 15 are formed with through holes in the portions corresponding to the guide shaft 61. .. When incorporating the solar panel 7 and the dial 15, the solar panel 7 and the dial 15 are placed on the module 6 by aligning the pointer shaft 61 so as to be inserted into the through holes of the solar panel 7 and the dial 15. Deploy. Further, the pointer 5 is attached to the pointer shaft 61 of the watch 100.
Then, the module 6, the solar panel 7, the dial 15, and the pointer 5 are arranged in the watch case 1 in which the opening on the back surface side is closed by the back cover member or the like. Further, by fitting the windshield member 13 into the opening on the visual side of the watch case 1, the opening is closed, and the watch 100, which is a pointer display device, is completed.
In the clock 100 having such a pointer 5, the pointer 5 (in the present embodiment, the minute hand (minute hand) 5a and the minute hand (hour hand) 5b) moves to move a part of the pointer 5 (digital display unit 4a). , 4b), but the portion of the pointer 5 (in this embodiment, the long hand (minute hand) 5a and the short hand (hour hand) 5b) that overlaps with the digital display unit 4 (digital display units 4a, 4b) provides light transmission. It is a light transmitting portion 52 having. Therefore, even if the pointer 5 overlaps with the digital display unit 4, the display content can be visually recognized via the light transmitting unit 52, and it is possible to avoid deterioration of the visibility of the digital display unit 4.
Further, although the solar panel 7 is arranged behind the pointer 5 in the incident direction of light, the pointer 5 is attached to the solar panel 7 because the light transmitting portion 52 is provided in a part of the pointer 5. It is possible to prevent the amount of light incident on the solar panel 7 from being overlapped and reduced.
On the other hand, since the visual recognition processing layer 53 is provided on the portion of the pointer 5 that points to the hour-shaped member 16 and the like to form the visual recognition portion 54 with improved visibility, it is confirmed where the pointer 5 points. It is easy to do, and the visibility as the pointer 5 can be sufficiently ensured.

As described above, according to the present embodiment, the pointer 5 includes a light transmitting portion 52 having light transmission and a viewing portion 54 made of a material having excellent visibility.
Therefore, even if a part of the pointer 5 overlaps with the digital display unit 4 due to the hand movement operation, the display of the digital display unit 4 can be confirmed via the light transmitting unit 52 and displayed on the digital display unit 4. It is possible to ensure the visibility of various displays to be displayed.
In particular, in the present embodiment, the portion of the pointer 5 that overlaps with the digital display portion 4 at least during the hand movement operation is the light transmitting portion 52. Therefore, the visibility of the digital display unit 4 can be reliably ensured.
Further, since the pointer 5 is arranged above the solar panel 7, the light is blocked by the pointer 5, the light receiving efficiency of the solar panel 7 is lowered, and a decrease in the amount of power generation becomes a problem. In particular, when a wide and large pointer 5 is used in the design of the clock 100, the light receiving efficiency of the solar panel 7 is significantly reduced.
In this respect, in the present embodiment, a part of the pointer 5 is a light transmitting portion 52 that transmits light. Therefore, the amount of light blocked by the pointer 5 can be suppressed, and a sufficient amount of power generation by the solar panel 7 can be secured.
In addition, since the influence of the solar panel 7 on the amount of power generation can be suppressed in this way, the degree of freedom in the shape of the pointer 5 is improved, and the guideline 5 with a wide variety of designs such as the guideline 5 with a wide design is displayed as a guideline. It is also possible to arrange it on the clock 100, which is a device.
By improving the degree of freedom in the design of the guideline 5 in this way, it is possible to realize a watch 100 having an excellent design that enables a wide variety of designs.
On the other hand, the pointer 5 is provided with a visual recognition unit 54 having excellent visibility. Therefore, the visibility as the guideline 5 can be sufficiently ensured.
In particular, in the present embodiment, the visual recognition unit 54 is provided at least at the tip of the pointer 5. Therefore, it is easy to confirm where the pointer 5 is pointing, and it is possible to realize an analog display unit 3 having excellent visibility.
Further, in the present embodiment, the visual recognition unit 54 contains a fluorescent substance or a phosphorescent substance. As a result, the visibility as the pointer 5 can be sufficiently ensured even at night or in a dark place.
Further, the clock 100, which is the pointer display device of the present embodiment, includes a solar panel 7 that generates electricity by irradiating light. Therefore, various functional units such as the display unit 3 can be operated without the need for battery replacement or the like.
Even in this case, since a part of the pointer 5 is a light transmitting portion 52 having light transmission, the power generation efficiency of the solar panel 7 can be made good, and various functional units can be operated. The required amount of power generation can be secured.
Further, the clock 100, which is the pointer display device of the present embodiment, includes a digital display unit 4. As a result, various time displays and function displays can be performed digitally.
Even in this case, a part of the pointer 5 is a light transmitting portion 52, and particularly in the present embodiment, a portion overlapping with the digital display unit 4 is a light transmitting portion 52 having light transmission. Therefore, even if the digital display unit 4 is provided within the rotation range of the pointer 5, its visibility is not impaired.
Therefore, it is possible to realize a clock 100 having high visibility in both the analog display unit 3 and the digital display unit 4.

[Second Embodiment]
Next, a second embodiment of the guideline, the pointer display device, and the timepiece according to the present invention will be described with reference to FIGS. 5 and 6. In the embodiment described below, a case where the pointer is provided on the timepiece which is the pointer display device will be described as an example as in the first embodiment. Since this embodiment differs from the first embodiment only in the configuration of the guideline, the points different from the first embodiment will be described below.

FIG. 5 is a plan view of the pointer in the present embodiment, and FIG. 6 is a cross-sectional view taken along the VI-VI line of the portion surrounded by the alternate long and short dash line in FIG.
As shown in FIGS. 5 and 6, the guideline 8 of the present embodiment has a light transmitting portion 82 having light transmission and a viewing portion 84 made of a material having excellent visibility, as in the first embodiment. And have.
Specifically, the entire pointer 8 is composed of a synthetic resin such as acrylic resin that is transparent or semi-transparent to light, and a base material 81 made of a light-transmissive material such as transparent or semi-transmissive glass. The light transmitting portion 82 is provided by providing a notch along the extending direction of the pointer 8 at the tip side of the pointer 8 and substantially the center portion in the width direction of the pointer 8. It is formed.
As in the first embodiment, the position and range of the notch portion constituting the light transmitting portion 82, the shape of the cutout portion, and the like are determined by the digital provided below the guideline 8. It is appropriately determined depending on the part where visibility is required such as the display unit, the position and range of the solar panel, and the like.
Further, the area other than the light transmitting portion 82 (that is, the notch portion) in the pointer 8 (that is, the edge portion of the pointer 5 in the present embodiment) is visually recognized as being coated with a paint containing a fluorescent substance or a phosphorescent substance. A processed layer 83 is provided. In the present embodiment, the portion provided with the visual recognition processing layer 83 is the visual recognition portion 84.

As described above, by providing the visual recognition portions 84 at the tip portion of the pointer 5 and the both end edges in the width direction of the pointer 5, the entire pointer 8 is formed of a light-transmitting base material 81 such as a transparent acrylic resin. Even when the case is used, high visibility is ensured in a part where visibility is particularly required, such as a part pointing to the hour-shaped member 16.
Further, since the light transmitting portion 82 is provided along the extending direction of the pointer 8, even when the digital display portion composed of the liquid crystal panel or the like is arranged below the pointer 8, the light transmitting portion 82 is provided. The display contents of the digital display unit can be confirmed via.

Since the other configurations are the same as those in the first embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted.

Next, the guideline in the present embodiment and the operation of the clock, which is a guideline display device to which the guideline is applied, will be described.

In the present embodiment, in order to form the guideline 8, the base material 81 is first formed by insert molding or the like.
In the present embodiment, a notch is formed along the extending direction of the pointer 8 at the tip side of the hakama portion 55 and substantially at the center of the pointer 8 in the width direction. The notch portion may be provided when the base material 81 is formed, or may be formed by notching after the base material 81 is formed.
Next, various surface treatments such as applying a paint containing a fluorescent substance or a phosphorescent substance to the entire surface (the surface on the visual side in this embodiment) of the base material 81 on which the notch portion is formed are applied. The visual processing layer 83 is formed by performing a decoration treatment or the like.
In the present embodiment, the portion provided with the visual processing layer 83 becomes the visual recognition portion 84, and the portion where the visual recognition processing layer 83 is not formed (that is, the notched portion) transmits light. It becomes.
As a result, the guideline 8 is completed.

Since the point of assembling the watch which is the pointer display device by incorporating the pointer 8 completed in this way into the watch case is the same as that of the first embodiment, the description thereof will be omitted.

Since the guideline 8 of the present embodiment constitutes the light transmitting portion 82 by cutting out a part of the base material 81, the guideline 8 can be made lighter.
Further, in a clock having such a pointer 8, a part of the pointer 8 overlaps with the digital display unit by moving the hand, but the portion of the pointer 8 that overlaps with the digital display unit has light transmission. Since the unit 82 is formed, even if the pointer 8 overlaps with the digital display unit, the display content can be visually recognized via the light transmitting unit 82, and it is possible to avoid deterioration of the visibility of the digital display unit. it can.
Further, although the solar panel is arranged behind the pointer 8 in the incident direction of light, the pointer 8 overlaps with the solar panel because the light transmitting portion 82 is provided in a part of the pointer 8. It is possible to suppress a decrease in the amount of light incident on the solar panel.
On the other hand, since the visual recognition processing layer 83 is provided on the side edge of the pointer 8 on the tip end side, which is the portion of the pointer 8 that points to the hour-shaped member 16 and the like, the visual recognition portion 84 has improved visibility. , It is easy to confirm where the pointer 8 points, and the visibility as the pointer 8 can be sufficiently ensured.

As described above, according to the present embodiment, the same effect as that of the first embodiment can be obtained, and the following effects can be obtained.
That is, in the present embodiment, since the light transmitting portion 82 is formed by cutting out a part of the base material 81, the pointer 8 becomes lighter. Therefore, it is possible to easily rotate even with a small force. Further, even if the width and length of the pointer 8 are increased, distortion and bending are less likely to occur, and the degree of freedom in designing the pointer 8 is improved. As a result, the design of the pointer 8 itself is improved, and the degree of freedom in designing the watch as a pointer display device incorporating the pointer 8 is further improved, so that a watch having excellent design can be realized.
Further, since the light transmitting portion 82 is composed of the cutout portion, the digital display portion or the like arranged below the pointer 8 can be directly visually recognized without passing through the base material 81, so that, for example, a transparent base material can be visually recognized. It is possible to realize even better visibility than when visually recognizing through.
Further, in the present embodiment, since all the portions other than the light transmitting portion 82, such as the tip end portion and both side edge edges of the pointer 8 are the visual recognition portion 84, it is easy to confirm where the pointer 8 is pointing, and the pointer is easy to check. The visibility as 8 can be sufficiently ensured.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to such embodiments and can be variously modified without departing from the gist thereof.

For example, in each of the above embodiments, the visible processing layers 53 and 83 may be formed of a material having excellent visibility and can improve the visibility of the pointers 5 and 8, and the phosphorescent paint is applied. It is not limited to those composed of. For example, the visible processing layers 53,83 are subjected to various surface treatments such as sticking of fluorescent or phosphorescent sheets, vapor deposition of materials capable of improving visibility, painting, printing, etc., and decoration treatments. May be formed.

The guideline of the present invention can be applied even when only one body is provided or when neither body is provided.
For example, when a watch has only a solar panel and does not have a digital display, the base material is made of a translucent resin that transmits light, so that the light transmittance is high and the visibility is good. It can be used as a guideline.

Further, in each of the above embodiments, the pointer is composed of one member. For example, the light transmitting portion is made of a material having high light transmittance, and the visible portion is made of a material having high visibility (for example, a fluorescent substance or a phosphorescent substance). It may be formed of a synthetic resin or the like containing a substance or the like) and joined to form a pointer having a light transmitting portion and a visible portion.

Further, in each of the above-described embodiments, an example is shown in which two pointers (hour hand and minute hand) are provided and these are used as guidelines having the configuration shown in each of the above-described embodiments, but the number and types of pointers are limited to this. Not done. For example, three guidelines including the second hand may be provided, and the guidelines of the present invention may be applied to all of them. Further, the guideline of the present invention may be applied to various functional needles.
Further, it is not necessary to apply the pointer of the present invention to all the pointers provided by the timepiece. For example, when the hour hand, the minute hand, and the second hand are provided as pointers, the pointer of the present invention is applied to the hour hand and the minute hand, and the second hand is made of metal. It may be used as a needle.

Further, in the present embodiment, the case where the pointer is provided on the timepiece is illustrated, but the guideline display device to which the guideline of the present invention can be applied is not limited to the timepiece.
As long as the display device has a guideline, the guideline of the present invention can be widely applied.
