Description

  The present invention relates to a timepiece that displays time, and more specifically, a timepiece that irradiates light to a divided partition area to improve the visibility and design of a display object provided in the partition area. It is about.

  In general, a watch is configured to indicate the time with a long hand and a short hand, but in addition to indicating the time with a long hand and a short hand, the watch is generally illuminated by illuminating the partitioned area where the long hand and the short hand are present. A clock that informs the time is also proposed.

  For example, in Patent Document 1 below, a timepiece displayed on a display or the like is configured such that a display screen constituting a dial is divided into 12 parts for each time area, and a divided area indicated by a long hand or a short hand is illuminated. Watch has been proposed. According to such a configuration, it is possible to notify the approximate time only by looking at the shining partition area, and it is possible to notify the time even in a dark place.

  By the way, when a clock is used as a large clock such as a monument, there are cases where it is desired to display a large number of display objects to viewers of the clock by displaying the display objects in the partition area. For example, there are cases where you want to appeal to visitors who have visited the area by displaying traditional crafts.

  However, there are many cases where a display object to be displayed is composed of a model that does not transmit light. When such a display object is arranged and displayed in a partition area, light must be irradiated from the surface or side surface of the display object.

  However, when light is irradiated from the surface or side surface in this way, light leaks to the outside of the divided partitioned area, so that the partitioned area becomes vague and the brightness of the partitioned area does not stand out. Since each display object cannot be displayed clearly, there is not much difference from the case of displaying by a normal display method, and it is difficult to leave an impression. In addition, when such a watch is installed in a bright place in an indoor space, external light such as an illuminating lamp passes through the front glass surface and illuminates the display objects in all the partitioned areas. It becomes clear, and even if display items are displayed, it cannot attract attention.

  In addition, there are three-dimensional objects such as ceramics and metal crafts in such display objects, but if such three-dimensional objects are irradiated with light from the surface side, the three-dimensional effect disappears. As a result, there is a problem that the design is impaired.

  Therefore, in order to solve the above-described problems, the present invention, when a display object having light impermeability is attached to a partitioned area, irradiates light so as not to leak light to the other partitioned areas, and three-dimensionally covers the partitioned areas. An object of the present invention is to provide a timepiece that does not impair the three-dimensional appearance of the three-dimensional modeled object when the modeled model is provided.

  That is, in order to solve the above-described problem, the present invention provides a divided time zone, a light source that emits light from the side of the time zone, and a light that is emitted to the time zone. Shielding means for preventing leakage to areas other than the partition area is provided.

  With this configuration, even when light is irradiated from the side of the divided partition area, the light is not leaked to other partition areas by the shielding means, and is provided in the partition area. It will be possible to illuminate only display items such as traditional crafts.

  Moreover, in such an invention, it comprises so that a half mirror may be attached to the surface of a division area.

  If comprised in this way, since the light from the outside is reflected outside by the half mirror, the light from the outside is not allowed to enter the partition area, and other display objects can be hidden. Moreover, since the light irradiated from the inside can be transmitted to the outside through the half mirror, only the display object in the partitioned area can be visually recognized.

  Further, the long hand and the short hand are provided in a circular area close to the center of rotation, and the partition area is provided in an outer area through a boundary wall.

  With this configuration, in the case where the long hand and the short hand are displayed with a thin light beam, the needle rotating part and the partition region are separated via the boundary wall, so the light beam of the needle and the light of the partition region overlap. The needle will not disappear.

  In addition, the display object is arranged in such a partitioned area so that the side away from the light source is inclined upward.

  By configuring in this way, the display object is inclined, so that the entire surface of the display object can be irradiated with light, and when the display object is a three-dimensional object, a shadow is created. , It becomes possible to give a more stereoscopic effect.

  According to the present invention, in a timepiece that displays time, a divided partitioned area, a light source that emits light from the side of the partitioned area, and light irradiated to the partitioned area leak to an area other than the partitioned area. Since the shielding means is provided so that the light is irradiated from the side of the divided partition area, the light can be leaked to other partition areas by the shielding means. Disappear. As a result, it is possible to show the display object more impressively by illuminating only the display object such as the traditional crafts provided in the partitioned area.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The timepiece 1 in this embodiment is used as a monument having a diameter of about 1 to 2 meters installed in a building or an outdoor facility. As shown in FIG. 5, a long hand 34a and a short hand 34b are provided. A display rotating unit 3 for displaying the time by rotating, an exhibition area unit 5 for displaying display objects 8 such as traditional crafts outside the rotating unit 3 as shown in FIG. A light source 6 for irradiating light is provided for each of the partitioned areas 53 of the display area section 5. Characteristically, the display object 8 provided in the partition area 53 is irradiated with light from the side, and the display area 5 is provided with a shielding means such as a side wall 51 to surround the partition area 53, thereby The light from the light source 6 is prevented from leaking to the other partitioned areas 53. Hereinafter, embodiments of the present invention will be described in detail.

  First, as shown in FIG. 2, the watch body 2 is provided so as to be surrounded by a circular outer wall 21, and is provided with a hand rotation part 3 at the center part and an exhibition area in the outer area. The part 5 is provided.

  The hand rotation unit 3 is provided inside a region surrounded by the boundary wall 4, and the time can be displayed by rotating the long hand 34a and the short hand 34b inside. When displaying the long hand 34a and the short hand 34b, various methods can be used. Here, as shown in FIGS. 1 and 2, the time can be displayed by irradiating thin linear light rays radially. I am doing so. Specifically, when displaying the time with such a thin light beam, first, as shown in FIGS. 1 to 3, a plurality of radial bottomed grooves 32 are formed in a conical metal plate 31 having a depressed central portion. The upper and lower light sources 33 are provided inside a slit (not shown) on the base end side of the bottomed groove 32. Then, by irradiating light from the light source 33 toward the outside, the direction along the bottomed groove 32 is illuminated and displayed as a needle. When distinguishing the long hand 34a and the short hand 34b of this light beam, the long hand 34a and the short hand 34b can be distinguished by selecting the LEDs provided at the top and bottom. By irradiating light, it is made to appear as the long needle 34a, and by illuminating the lower LED, light is irradiated nearby to make it appear as the short hand 34b. By the way, when displaying a needle | hook with a radial ray in this way, the light may leak to the division area | region 53. FIG. For this reason, by providing the boundary wall 4 outside the needle rotating part 3, the light is prevented from leaking to the outer display area part 5. Here, the hands are displayed using light rays, but in addition to this, the long hands 34a and the short hands 34b may be displayed using a liquid crystal panel. Alternatively, the long needle 34a and the short hand 34b that physically rotate may be used.

  The display area 5 is provided in an area surrounded by the outer side of the boundary wall 4 and the inner side of the outer wall 21 of the watch body 2, and is configured to have a plurality of partition areas 53 that are radially divided from the central portion. ing. This divided partition area 53 is divided into 12 corresponding to each time, and by providing a side wall 51 that constitutes a shielding means between the adjacent partition areas 53, light is transmitted to the adjacent partition areas 53. I try not to let it leak. Here, the divided area 53 is divided into 12 corresponding to the time, but the number of divisions is not limited to this.

  In the case of irradiating light within the partitioned area 53, the partitioned area 53 is illuminated by irradiating light from a plurality of light sources 6 provided on the boundary wall 4. The light source 6 is composed of a plurality of LEDs attached along the outer peripheral direction of the boundary wall 4. In the state where light is diffused by a diffusion plate (not shown) provided in front of the light source 6, The light is irradiated.

  The partition area 53 is provided with a base portion 52 for displaying the display object 8. As shown in FIG. 3, the base portion 52 is attached in a state where the display object 8 is tilted, and lowers the light source 6 side and raises the side far from the light source 6. , So that it can be tilted. The display object 8 has a fan shape stored in the partition area 53, and here, traditional crafts are used. As such traditional crafts, flat or three-dimensional objects having light impermeability such as woven crafts, ceramics, bamboo crafts, lacquer crafts, metal crafts, etc. are used. It is provided so as to constitute a part of a unified design over the region 53.

  On the other hand, as shown in FIG. 3, a printing layer 71, a half mirror 72, and a glass layer 73 are provided in order from the bottom on the surface side of the needle rotation unit 3 and the display area unit 5.

  The printed layer 71 forms a design that is visible from the surface of the timepiece 1 and is formed so as to arrange a design having a predetermined light transmittance. And by the design, while concealing the side wall 51 of the partition area | region 53, the metal plate 31 etc. of the needle | hook rotation part 3 can also be concealed. The light transmittance of the print layer 71 is set so as to have such a transmittance that the light of the needle of the needle rotating unit 3 can be visually recognized from the outside, and thereby the metal plate 31 of the needle rotating unit 3. And the side wall 51 can be hidden.

  The half mirror 72 prevents outside light from the front side (for example, indoor lighting or sunlight) from entering the needle rotating unit 3 or the display area unit 5 and is provided inside the film. A reflective film deposited with metal is formed and provided. Due to the difference in refractive index from this reflective film, the inner light is transmitted to the outer side, and the light from the outer side is reflected so as not to enter the inner side.

  The glass layer 73 provided on the surface of the half mirror 72 covers the needle rotation unit 3 and the display region unit 5 and covers the circular region surrounded by the outer wall 21 so that the inside can be protected. .

  Next, a method for displaying the time using the timepiece 1 configured as described above will be described.

  First, when the time is displayed using the long hand 34a and the short hand 34b, as shown in FIG. 5, light is emitted from the upper and lower light sources 33 at the center portion so that the long hand 34a and the short hand 34b are displayed at positions corresponding to the time. The light of the long needle 34a and the short hand 34b is displayed in the bottomed groove 32 through the slit. Then, the light of the displayed long needle 34a and short hand 34b is transmitted through the printing layer 71, the half mirror 72, the glass layer 73, and the like so as to be visually recognized from the outside.

  On the other hand, in the display area part 5 provided outside the hand rotating part 3, the partition area 53 corresponding to the time is illuminated, so that the time can be easily grasped. At this time, the light emitted from the light source 6 is uniformly diffused by the diffusion plate and emitted toward the outside to illuminate the inclined display object 8. At this time, the light emitted from the light source 6 toward the half mirror 72 is reflected by the half mirror 72, and the light emitted toward the side wall 51 is reflected by the side wall 51 and is partitioned again. The display object 8 in the area 53 is illuminated. At this time, when a three-dimensional display object 8 having unevenness is attached as the display object 8, an appropriate shadow can be created by the unevenness as shown in FIG. 4B, and light is irradiated from the surface. Compared with the case (FIG. 4A), the display object 8 can have a stereoscopic effect. Then, the light irradiated on the display object 8 in this way is transmitted to the outside through the half mirror 72 so that the display object 8 is visually recognized from the outside.

  On the other hand, light emitted from the outside such as indoor lighting is reflected to the outside by the half mirror 72, and the light that is partially transmitted is blocked by the printing layer 71. Further, with respect to the partitioned area 53 where the print layer 71 does not exist, the light irradiated from the outside by the half mirror 72 is reflected, thereby making it impossible to visually recognize the partitioned area 53 from the outside. On the other hand, the light emitted from the long hand 34a and the short hand 34b or the partition area 53 irradiated on the inside of the watch body 2 is transmitted to the outside through the half mirror 72, and the long hand 34a, the short hand 34b and the partition area from the outside. 53 display objects 8 can be visually recognized. At this time, since the light emitted from the light source 6 in the partitioned area 53 does not leak to the adjacent partitioned area 53 by the side wall 51, only the fan-shaped partitioned area 53 is clearly displayed, and the display object 8 And the time area can be clearly displayed.

  As described above, according to the above-described embodiment, in the timepiece 1 that displays the time by the hands composed of the long hands 34a and the short hands 34b, the partition area 53 that is radially divided from the rotation center of the hands (34a, 34b), The light source 6 that irradiates light from the side of the partition region 53 and the side wall 51 (shielding) that prevents the light irradiated to the partition region 53 where the long needle 34 a and the short hand 34 b exist from leaking to regions other than the partition region 53. Means), even if light is irradiated from the side of the divided partition region 53, the light is not leaked to the other partition region 53. As a result, it is possible to display only the display object 8 such as the traditional crafts provided in the partition area 53 by illuminating it, and to display the time clearly.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, according to the above-described embodiment, the display object 8 has been described by taking traditional crafts as an example. However, the display object 8 is not limited thereto, and art objects, animations, characters, photographs, and the like are displayed. May be.

  Further, in the above embodiment, the display object 8 is attached to be inclined, but the display object 8 is provided in parallel with the glass layer 73 and light from the light source 6 such as an LED is irradiated from an oblique direction. May be.

  Further, in the above embodiment, when the display object 8 is tilted, the center portion is arranged so as to be lowered. On the contrary, the display object 8 is disposed so that the center portion is inclined. Also good. In this case, the light source 6 is provided on the outer wall 21.

  Moreover, in the said embodiment, although light was uniformly irradiated from the light source 6 of the division area | region 53, the light source of the position corresponding to the direction of a needle | hook among several light sources 6 provided along the outer peripheral direction. 6 may be irradiated with strong light so as to make it appear that the needle exists in the partitioned region 53.

  Moreover, in the said embodiment, although light was irradiated only to the division area | region 53 which the long needle 34a and the short needle 34b point, about the division area 53 other than this, while irradiating light thinly from an inner side and pointing to a needle | hook The partition area 53 may be irradiated with strong light. Alternatively, all the display objects 8 may be made visible at the same time by causing all the partitioned areas 53 to shine simultaneously at predetermined time intervals.
