  By the way, conventional manufacturing has focused on how to make high-performance and highly reliable products at a low price. However, in recent years, product manufacturing capabilities have also improved in developing countries other than Japan. Therefore, other countries other than Japan are beginning to have strengths in terms of evaluation such as price vs. function and performance.

  Therefore, in order for the Japanese manufacturing industry to survive, it is important to appeal to customers with new evaluation axes in addition to improving costs and functions as before. One of them is to increase the sensitivity value (KANSEI Value).

  Sensitivity value is the value that is recognized by obtaining impression and empathy from consumers, apart from performance, function, and cost. Sensitivity value has attracted attention in recent years as a new evaluation axis for product value.

  The “Monozukuri White Paper 2006” issued by the Ministry of Economy, Trade and Industry in 2007 suggested that increasing sensitivity value in addition to technological strengths could be a differentiating product from other countries. Attracted interest. The Ministry of Economy, Trade and Industry defines sensitivity values as “values that are manifested by acting on the sensibilities of consumers and gaining emotion and empathy”.

  Increasing sensibility value can stimulate new demand for products. In particular, in mature industries where it is difficult to differentiate the products offered by each company (for example, the watch manufacturing industry), product development from the perspective of sensitivity value has the power to stimulate new demand.

  Each of the conventional watches described above achieves the above-mentioned effects by using a transparent or translucent material. These effects can be used to make a high-performance and reliable product at a low price. It is difficult to say that each of the above effects enhances the sensitivity value of the watch.

  Therefore, an object of the present invention is to provide a timepiece that has a high sensitivity value and can increase the consumer's willingness to purchase by obtaining impression and empathy from the consumer.

  The invention described in claim 1 is a timepiece having a character substrate and an indicator provided on the character substrate, which is made of a transparent body or a semi-transparent body.

  The invention according to claim 2 is the timepiece according to claim 1, wherein the indicator is formed with a surface through which light can be transmitted and facing the front side.

  The invention according to claim 3 is the timepiece according to claim 1 or 2, wherein a light-shielding film is provided on a surface on the front side of the indicator.

  According to a fourth aspect of the present invention, in the timepiece according to any one of the first to third aspects, the character board has a plate-like bottom portion and a cylindrical shape that stands up from the outer periphery of the bottom portion. The indicator is formed in a columnar shape, and one end portion is located on the side portion side and the other end portion is located on the bottom side. And the character substrate.

  The invention according to claim 5 is the timepiece according to any one of claims 1 to 4, wherein the light that has entered the indicator comes out of the indicator from the side surface of the indicator, The timepiece is configured to be projected onto the character board.

  According to the present invention, there is an effect that it is possible to provide a watch that has a high sensitivity value and can increase the consumer's willingness to purchase by obtaining impression and empathy from the consumer.

[First Embodiment]
As shown in FIGS. 1 and 2, the wall clock 1 according to the first embodiment of the present invention includes a character board 3 and an index 5 provided on the character board 3.

  The index 5 is composed of a transparent resin or a translucent material such as a synthetic resin such as acrylic or glass. The index 5 may be colorless and transparent, or may be colored and transparent. In this embodiment, it is light blue or light green transparent.

  The index 5 is formed in a three-dimensional shape (a shape of a three-dimensional spatial object such as a quadrangular prism), and is provided on the front side of the character board 3. Thus, the index 5 protrudes from the surface of the character board 3 on the front side (front side of the wall clock 1; front side).

  The index 5 is formed with a surface (cut surface) 7 through which light can be transmitted and facing the front side. A light shielding film 11 is provided on a surface 9 (surface other than the cut surface 7) 9 of the index 5.

  The character substrate 3 includes a flat plate-like (for example, circular flat plate-like) bottom portion 13 and a cylindrical (for example, cylindrical) side portion 15 erected from the outer periphery of the bottom portion 13 so as to have a dish shape (Petri dish shape). A shape of a short cylindrical bowl). More precisely, the side part 15 has a truncated cone side surface shape. In this case, the small-diameter side of the truncated cone is located on the bottom 13 side (rear side), and the large-diameter side is located on the side opposite to the bottom 13 (front side; the opening side of the character board 3). Further, the boundary between the bottom portion 13 and the side portion 15 has an arc shape.

  The indicator 5 is formed in, for example, an elongated column shape. The indicator 5 has one end in the longitudinal direction located on the side 15 side of the character board 3 and is engaged with the side 15 at the opening side (front side) of the side 15 to be integrated with the character board 3. It has become. Further, the other end of the index 5 in the longitudinal direction is located on the bottom 13 side of the character board 3. More specifically, the indicator 5 is engaged with the bottom portion 13 at the other end portion in the longitudinal direction at the center side portion of the bottom portion 13 away from the outer periphery of the bottom portion 13 of the character substrate 3.

  As a result, the index 5 extends obliquely, and a triangular prism-shaped space 17 is formed between the index 5 and the character board 3 (the boundary between the bottom portion 13 and the side portion 15 and the periphery of the boundary). . That is, the space 17 is formed by the intermediate portion in the longitudinal direction of the index 5 being away from the character substrate 3.

  In FIG. 2B, the other end portion (pointed ridge portion) in the longitudinal direction of the index 5 is only in contact with the bottom portion 13 of the character substrate 3, but a small concave portion is formed on the bottom portion 13 of the character substrate 3. It is also possible to adopt a form in which the other end portion of the index 5 in the longitudinal direction is provided in the concave portion.

  The wall clock 1 will be described in more detail.

  For convenience of explanation, one horizontal direction is a left-right direction, another horizontal direction is a front-rear direction (front and back direction), and a vertical direction is a vertical direction.

  The wall clock 1 is used by being hung on a wall or the like, for example. The wall clock 1 hung on the wall has the rear side (back side) facing the wall, and the front side (front side) faces the room side. The time is displayed at the front part facing the room side.

  The wall clock 1 includes a character board 3, an index 5, a pointer (hour hand and minute hand or hour hand and minute hand and second hand) 21, and a solar cell (solar panel) 23.

  As described above, the character board 3 having the disc-like bottom portion 13 and the side portion 15 having the cylindrical side surface shape or the truncated cone side surface shape and having a dish shape has the thickness direction of the bottom portion 13 as the front-rear direction. In this case, the cylindrical side portion 15 protrudes from the outer periphery of the bottom portion 13 to the front side by a predetermined length (in FIG. 2B, protrudes to the left side).

  In the center of the bottom portion 13, for example, a circular through hole (a solar cell through hole penetrating the bottom portion 13 in the thickness direction) 25 is formed. The center of the bottom portion 13 and the center of the through hole 25 coincide with each other.

  At least the front surface of the character substrate 3 (the front surface of the bottom portion 13 and the inner peripheral surface of the side portion 15) is colored white or black (in this embodiment, covered with a white film). That is, the surface of the concave portion of the plate-like character substrate 3 is painted white). The character substrate 3 is configured to block light (visible light) by at least one of the film and the flesh portion of the character substrate 3.

  The index 5 is formed in a long rectangular column shape. However, as shown in FIG. 3, the bottom surface 7 and the top surface 27 of the square columnar index 5 are not orthogonal to the height direction (longitudinal direction of the index 5) but are inclined obliquely.

  Further, one of the four side surfaces 9, 29, 31, 33 is arranged such that one side surface (the side surface located on the front side in the wall clock 1; the front side surface) 9 is not a parallelogram but a rectangle (FIG. 3 ( The bottom surface 7 and the top surface 27 are formed so that the angles θ1, θ2, θ3, θ4 shown in a) are all at right angles.

  Further, the intersection angle θ6 between the upper surface 27 and the front side surface 9 is larger than the intersection angle θ5 between the bottom surface 7 and the rear side surface (one side surface parallel to the front side surface 9) 29 (FIG. 3B). reference).

  The quadrangular columnar index 5 has four side surfaces, and one of the four side surfaces is the front side surface 9, and one side surface facing the front side surface 9 is the rear side. It becomes the side surface 29. Furthermore, the other two side surfaces 31 and 33 are side surfaces.

  A light shielding film 11 is provided on the front side surface 9 of the index. On the five surfaces (the upper surface 27, the bottom surface 7, and the three side surfaces 29, 31, 33) other than the front side surface 9 of the square columnar index 5, the material constituting the index 5 is exposed. Further, the bottom surface 7 of the square columnar index 5 is a cut surface.

  Light is transmitted through five surfaces 7, 27, 29, 31 and 33 other than the front side surface 9 of the square columnar index 5. That is, light enters the index 5 from the outside of the index 5 through the five surfaces 7, 27, 29, 31, 33 other than the front side surface 9, and from the inside of the index 5 to the outside of the index 5. Light is emitted.

  More specifically, for example, light that has entered the flesh portion of the index 5 from one side surface 31 is reflected, refracted, or diffused and emitted from the cut surface 7, and the other one side surface. The light is emitted from the side surface 33.

  As shown in FIGS. 1 and 2, for example, a plurality of indicators 5 (12 in the wall clock 1) are provided. Each index 5 is arranged at a position indicating a time such as 12:00, 1 o'clock, 2 o'clock, etc.

  Each index 5 is radially arranged around a central axis C1 (for example, an axis extending in the front-rear direction through the center of the character board 3) of the pointer (hour hand, minute hand) 21. More specifically, each indicator 5 is disposed outside a circular area (outside of the solar cell through hole 25) around which the pointer (hour hand, minute hand) 21 rotates and the pointer (hour hand, minute hand) 21. Are arranged at positions to distribute the circumference of a circle with a predetermined radius centered on the central axis C1.

  The square columnar index 5 has an upper surface 27 in contact with the side portion 15 of the character substrate 3 and a ridge located at the boundary between the bottom surface 7 and the rear side surface 29 in contact with the bottom portion 13 of the character substrate 3. It is provided inside the dish-shaped character substrate 3.

  The height direction (longitudinal direction) of each square columnar index 5 is a radial direction. In other words, if each square pillar-shaped index 5 is extended in this height direction, each index 5 and the central axis C1 of the pointer 21 intersect at almost one place.

  In addition, the index 5 has an inner side (the bottom surface 7 side of the square columnar index 5; the rotation center axis C1 side of the pointer 21) located on the rear side of the wall clock 1, and the outer side (the upper surface 27 of the square columnar index 5). The side of the character board 3 is inclined with respect to the central axis C1 of the pointer 21 so that the portion on the side 15 side of the character substrate 3 is positioned on the front side of the wall clock 1. Thereby, the triangular prism-shaped space 17 as described above is formed.

  Further, when viewed from the front-rear direction (when viewed from infinity in the front-rear direction), each index 5 is a character board so that the two side surfaces 31 and 33 of each index 5 appear as straight lines having no area. 3 is installed.

  The cut surface 7 is formed at the end on the central axis C1 side of the pointer 21 in each index 5. The cut surface 7 is not orthogonal to the central axis C1 of the pointer 21 but is inclined. Further, since the cut surface 7 faces the front side, the cut surface 7 can be seen when the wall clock 1 is viewed from the front side.

  The intersection angle θ11 between the cut surface 7 and the center axis C1 of the pointer 21 is smaller than the intersection angle θ12 between the front side surface 9 and the center axis C1 of the pointer 21 (see FIG. 2B).

  Here, the light shielding film 11 will be described in detail.

  The color of the light-shielding film 11 is the same color as the color of the character substrate 3 or the same color (color with a small contrast difference in hue, saturation, and brightness). The wall clock 1 is white.

  In the wall clock 1, the light shielding film 11 is a single layer, but the light shielding film 11 may be composed of a plurality of layers. For example, a configuration in which a light shielding film (regardless of color) is provided on the front side surface 9 of the index 5 and a white film (which may transmit light) is provided on the light shielding film may be provided.

  Furthermore, the surface (back surface) on the side in contact with the index 5 in the light shielding film 11 provided on the front side surface 9 of the index 5 may reflect light (may be a mirror surface).

  Further, for example, the entire surface of the index 5 on which the light shielding film 11 is not provided (cut surface 7, upper surface 27, rear side surface 29, side side surfaces 31, 33) is covered with a light transmitting material. It may be. Furthermore, at least one of the upper surface 27 and the rear side surface 29 may be covered with a light-shielding film in the same manner as the front side surface 9.

  Further, the wall clock 1 is provided with a windshield (windshield glass) 35, a movement (movement block) 37, a case 39, and the solar cell 23 described above.

  The solar cell 23 has a disk shape, for example, and is provided on the back side of the character substrate 3 so as to close the through hole 25 provided in the bottom portion 13 of the character substrate 3. The thickness direction of the solar cell 23 is the front-rear direction, similar to the bottom 13 of the character substrate 3. A small hole for the pointer 21 is formed at the center of the solar cell 23.

  A movement 37 is provided on the rear side of the solar cell 23. A case 39 is provided behind the character substrate 3, the solar cell 23, and the movement 37. And the case 39 covers the rear part of the character substrate 3, the solar cell 23, and the movement 37. The opening of the dish-shaped character substrate 3 is covered and closed with, for example, a disk-shaped windshield glass 35.

  Here, how the wall clock 1 gives consumers impression and empathy will be described with examples.

  When light such as sunlight is inserted into the wall clock 1 from an oblique side (front side) in a state where the wall clock 1 is hung on the wall and displaying the time, as shown on the left side of FIG. A pattern 41 with the index of 5 appears. In this pattern 41, light that enters the index 5 from one side surface 31 of the index 5 exits the index 5 from the other side surface 33 or the like of the index 5, and the light that has exited from the index 5 Appears on the character board 3 by being irradiated (projected) onto the character board 3. The pattern 41 appears for each index 5 and has a different form. Moreover, when light is sunlight, a form changes momentarily with the passage of time, and the impression and empathy by aesthetics etc. are given to what looked at the wall clock 1.

  That is, according to the wall clock 1, for example, when the clock 1 is exposed to light from the front side, a visually beautiful phenomenon (light pattern) 41 appears on the character board 3, and the visual effect is improved. That is, the wall clock 1 looks beautiful, and the visual quality (aesthetics) of the wall clock 1 is improved. Also, if the light is Asahi, the person who looks at the wall clock 1 feels a refreshing morning, and the person's feelings are enriched (for example, he feels happy today and works hard forward).

  Thereby, the sensibility value of the wall clock 1 is increased, and impression and empathy can be obtained from the consumer, and the consumer's willingness to purchase can be enhanced.

  Furthermore, according to the wall clock 1, the pattern 41 appears only when the wall clock 1 happens to be in a predetermined condition. Therefore, the person who watches the wall clock 1 is almost never bored with the pattern 41, and the person who watches the wall clock 1 over a long period of time gets a fresh impression and empathy.

  Further, according to the wall clock 1, the light that has entered the index 5 from the side surface 31 of the index 5 is emitted from the cut surface 7. Then, the cut surface 7 emits light and the index 5 is conspicuous. Thereby, even if the pattern 41 etc. shines by the morning sun etc., it becomes easy for the person who looks at the wall clock 1 to recognize time.

  Further, according to the wall clock 1, since the light shielding film 11 is provided on the front surface 9 of the index 5, the index 5 can be prevented from being conspicuous when the index 5 is irradiated with light. 5, the clear light pattern 41 appearing on the character board 3 stands out, and the sensitivity value of the wall clock 1 is further enhanced.

  Further, according to the wall clock 1, since the triangular prism-shaped space 17 is formed between the index 5 and the character board 3, when the wall clock 1 is exposed to light from the front side surface of the wall clock 1, it is shown in FIG. Thus, the arc-shaped beautiful light pattern 41 appears on the character board 3, and the sensitivity value of the wall clock 1 is further enhanced.

  Further, since the index 5 is formed in a quadrangular prism shape, the arc-shaped beautiful light pattern 41 appears on the character board 3 in a multiple manner (see reference numerals 41A, 41B, 41C in FIG. 4), and the sensitivity of the wall clock 1 Value is further increased.

  By the way, the wall clock 1 can be changed into various appropriate shapes. Here, some modified examples of the index 5 are illustrated.
